Paleoclimatology

Paleoclimatology is the study of climate prior to the widespread availability of records of temperature, precipitation and other instrumental data. NOAA is particularly interested in the last few thousand years because this is the best dated, best sampled part of the past climatic record and can help us establish the range of natural climatic variability in a period prior to global-scale human influence.

Environmental recorders are used to estimate past climatic conditions and thus extend our understanding far beyond the 100+ year instrumental record. "Proxy" records of climate have been preserved in tree rings, locked in the skeletons of tropical coral reefs, extracted as ice cores from glaciers and ice caps, and buried in laminated sediments from lakes and the ocean.

Green supercomputing paves the way for sharing scientific research and collaboration

Energy efficiency ranks second when compared to renewable power generation as a solution to climate change, but for Phillip Dickens, a professor at the University of Maine, it is first in the world of supercomputing.

With the evolution of supercomputers over the last few years, speed, memory and capability have increased tremendously. The early models of computers were enormous in size, often filling a large room. One of the challenges of having a computer this size was the large amount of heat that it generated and how to keep it cool. Two dominant factors that have influenced supercomputer design are Moore's Law and economies of scale.

Today, a modern desktop computer running at 2.66 GHz is more powerful than a 10-year-old supercomputer, and costs considerably less.

In addition, parallelization allows for several smaller parts to work simultaneously and limits the amount of information that can be transferred between processing units. Clusters of computers can also be programmed to function as a single large computer. There are many possibilities that can maximize the energy efficiency of the hardware and software of supercomputers.

Dickens received a two year, $200,000 National Science Foundation (NSF) research grant that funded the development of a scientific grid portal in Maine and the purchase of an energy efficient supercomputer. The purpose of the grid-portal is to make research from the University of Maine Institute of Climate Modeling available to top research scientists down to school age children.

Results of widely used ice sheet models, tools for climate change research, prototype versions of object based caching system, real-time animations and video are just a few of the applications that will be available. In addition, the grid portal will provide the larger community with the computing power, storage capacity, and rendering engine to execute very high-resolution models and receive animations and other visual information in real time.

In a demonstration of energy efficiency, the University of Maine, Department of Computer Science, unveiled the first cyclist-powered "green" supercomputer. Powered by 10 cyclists, the eco-friendly SiCortex SC648 supercomputer successfully ran a program demonstrating glacial melting for 20 minutes.

"The fact that a computer can be powered by a team of cyclists underscores how efficient computers have become," said University of Maine professor George Markowsky.

Computer scientists are continually searching for new ways to reduce the amount of energy it takes to operate computer systems. The SiCortex SC648 is the first of two low power HPC systems to be developed in the state of Maine. It combines desktop accessibility with low cooling requirements of a standard PC, but has the speed and power for high-productivity computing. The SC648 can develop, distribute, run multiple applications and uses 1000 watts of power. In addition to the SC648, the University of Maine has also invested in the SiCortex SC072. It provides answers to complex scientific computing challenges as quickly as conventional cluster computers, but at the fraction of the energy requirement using 300 watts of power. Both computer systems will power the University of Maine Scientific Grid Portal and provide access to computing resources, scientific applications and research animations.

"The computer industry is still in the early phase of realizing the importance of power consumption. Most computer users today don't think about energy and infrastructure costs when making a buying decision. With climate change looming, energy costs skyrocketing and the economy stumbling, power requirements are being thrust into the foreground," said James Bailey, marketing director of SiCortex.

Although Dickens is at the forefront of "green" supercomputing, his desire exceeds the current eco-friendly capabilities. "We are still in the beginning phase. It would have been nice to show multiple displays, all executing different phases, showing different processes. We have one application now and we are looking to get more because there is a lot of demand," he said.

The South Pole: A Premier Observatory

Astronomers work at the South Pole to take advantage of excellent viewing conditions. Cold, dry Antarctica will allow SPT to more easily detect the cosmic microwave background (CMB) radiation, the afterglow of the big bang, with minimal interference from water vapor. On the electromagnetic spectrum, the CMB falls somewhere between heat radiation and radio waves.

The CMB is largely uniform, but it contains tiny ripples of varying density and temperature. These ripples reflect the seeds that, through gravitational attraction, grew into the galaxies and galaxy clusters visible to astronomers today. The SPT's first key science project will be to study small variations in the CMB to determine if dark energy began to affect the formation of galaxy clusters by fighting against gravity over the past few billion years.

Galaxy clusters are groups of galaxies, the largest celestial bodies that gravity can hold together. "Our galaxy, the Milky Way, is in one of these clusters," Meyer said. "And these clusters of galaxies actually change with time."

The CMB allows astronomers to take snapshots of the infant universe, when it was only 400,000 years old. No stars or galaxies had yet formed. If dark energy changed the way the universe expanded, it would have left its "fingerprints" in the way it forced galaxies apart over the deep history of time. Different causes would produce a different pattern in the formation of galaxy clusters.

According to one idea, dark energy could be Albert Einstein's cosmological constant: a steady force of nature operating at all times and in all places. Einstein introduced the cosmological constant into his theory of general relativity to accommodate a stationary universe, the dominant idea of the day. If Einstein's idea is correct, scientists will find that dark energy was much less influential in the universe 5 billion years ago than it is today.

"Clusters weren't around in the early universe. They took a long time to evolve," Carlstrom said.

Another version of the dark energy theory, called quintessence, suggests a force that varies in time and space. Some scientists even suggest there is no dark energy at all, and that gravity merely breaks down on vast intergalactic scales.

To pinpoint when dark energy became important, SPT will use a phenomenon called the Sunyaev-Zeldovich effect, which distorts the CMB as it passes through the hot gas of intervening galaxy clusters. As the microwaves interact with gas in the clusters, some of the microwaves get kicked into a higher frequency. SPT will measure the slight temperature difference associated with the frequency change and produce an image of the gas in the cluster.

SPT can scan large regions of the sky quickly. Scientists expect it to detect thousands, or even tens of thousands, of galaxy clusters within a few years. "To get a meaningful constraint on dark energy through measuring galaxy clusters, you need something like this South Pole Telescope," Carlstrom said. "The cluster SZ [Sunyaev-Zeldovich] signals cover small patches in the sky relative to the intrinsic variations in the cosmic microwave background. To get the necessary resolution, you need a big telescope. Now we have one."

Senior members of the SPT team include William Holzapfel, Adrian Lee and Helmuth Spieler from the University of California at Berkeley and the Lawrence Berkeley National Laborator; Joe Mohr, from the University of Illinois at Urbana-Champaign; John Ruhl from Case Western Reserve University; Antony Stark, from the Harvard-Smithsonian Astrophysical Observatory; Matt Dobbs from McGill University; and Erik Leitch of NASA's Jet Propulsion Laboratory.

SLIPPERY ELM - Ulmus rubra, Muhl

EXCEPT FOR SCATTERED counties in the Ozarks, slippery elm is found in almost every county in the state. Like American elm, slippery elm is a water-loving tree and grows best on moist, rich soils on lowers slopes, stream banks, river terraces and bottomlands.

The leaf is alternate, simple, with a coarsely double saw-toothed edge. It ranges from five to seven inches long and two to three inches wide. It is egg-shaped with the broadest part above the middle and the base slightly uneven. The tip is drawn out to a long, narrow point. The upper surface of the leaf is dark green and very rough while the under-surface is lighter and hairy. This rough leaf distinguishes it from the American elm which has a smooth leaf.

The fruit occurs in clusters and each seed and stem is 3/4 inch long. A single seed is surrounded by a thin, papery wing, smooth around the edge. It is common to see small drifts of elm seeds along sidewalks in metropolitan areas after a heavy rain.

Twigs are slender to moderately stout. They are gray and very rough to the touch. The buds are egg-shaped, pointed and covered with dark chestnut-brown hairs. The bark on older trees is reddish-brown. It is furrowed with platy or scaly ridges and the inner bark contains a sticky sap once used as a medicine by Indians and pioneers.

Like American elm, the seeds, buds, and leaves of slippery elm furnish food for the gray and fox squirrel and deer.The wood of slippery elm is heavy, tough, and strong. Of all the elms, it has the best and most durable lumber. It is used in the manufacture of furniture and for many other uses. Because of intertwined fibers, it is hard to split with an axe. Unprotected piles of lumber will twist and warp.

Growing along with slippery elm may be American elm, black cherry, white ash, blue ash, black walnut, bitternut hickory, bur oak, basswood, silver maple, and white oak. This elm is also susceptible to Dutch elm disease and many leaf-chewing insects.

Fresh or Frozen, Defender Is a Good Potato

Long, white-skinned potatoes in the produce section of your supermarket might be "Defender"—the only commercially grown potato in the United States today with tubers and leaves that fend off late blight disease. Worldwide, late blight is generally regarded as one of the worst diseases of potatoes.

Besides starring as a fresh-market potato, Defender also can be processed into frozen products. ARS scientists in the Small Grains and Potato Research Unit , Aberdeen, Idaho, and the Vegetable and Forage Crop Research Unit, Prosser, Wash., worked with university colleagues to in Idaho, Oregon and Washington develop this superior spud. They put it through more than a decade of rigorous outdoor tests before making it available to growers, processors, potato-seed companies and others last year.

The plant's natural resistance to late blight allows growers to use either no fungicides—or much smaller amounts—to control the disease. This feature makes the potato ideal for conventional and organic farms alike.

Kimberlites

Active exploration for diamondiferous kimberlite pipes is ongoing in northeastern Namibia, where kimberlite indicator minerals (e.g. ilmenite, garnet, chrom-diopside) as well as micro-diamonds have been recovered.

Companies exploring for diamondiferous kimberlites include Motapa Diamonds Incorporation, Mount Burgess Mining N.L and DeBeers. Past exploration of kimberlite pipes within the Gibeon Kimberlite Province was unable to delineate diamondiferous kimberlites due to their off-craton setting. To date, no economic diamondiferous kimberlite pipes have been discovered, but great potential exists on both the Congo and Kalahari cratons.

Money Market Funds

Money market funds have relatively low risks, compared to other mutual funds (and most other investments). By law, they can invest in only certain high-quality, short-term investments issued by the U.S. government, U.S. corporations, and state and local governments. Money market funds try to keep their net asset value (NAV) — which represents the value of one share in a fund — at a stable $1.00 per share. But the NAV may fall below $1.00 if the fund's investments perform poorly.

Investor losses have been rare, but they are possible.Money market funds pay dividends that generally reflect short-term interest rates, and historically the returns for money market funds have been lower than for either bond or stock funds. That's why "inflation risk" — the risk that inflation will outpace and erode investment returns over time — can be a potential concern for investors in money market funds.

UK losing out to the new members of the EU in attracting FDI

With the expansion of the EU with ten new members in 2004, and more set to join in 2007, foreign investors have a much broader selection of lower-wage markets and skill sets from which to choose. The UK has positioned itself as a mature market, producing higher-value goods and services and with a highlyskilled workforce, and continues to be the leading investment location in Europe, according to the UNCTAD World Investment Report 2006.

In line with its positioning as a high-value market, the UK attracts more European headquarters and R&D projects than any other European country1. The UK's focus is to attract hi-tech companies, and exploit the wider aspects of innovation in a variety of knowledgedriven industries.

French and Italian painting of the 17th century

In Italy, the Counter-reformation helped drive a style of painting that was emotional and direct. Artists again emphasized careful observation of the natural world and looked to the examples of past masters. Their classical approach would leave its mark all over Europe for more than 100 years and, in France, would be institutionalized in the French Academy, founded in 1648. Fueled by the wealth of the Vatican and the spate of construction of new buildings, seventeenth-century Rome offered great opportunities for artists. Domenico Fetti saw the Veil of Veronica when it was exhibited at Saint Peter's in Rome and made it the subject of a moving portrayal of Christ in his suffering.

The French state from the sixteenth to the eighteenth centuries witnessed a form of government based on the absolute monarchy, which reached its apogee under the reign of the Sun King, Louis XIV, from 1643 until 1715. Louis' desire to glorify his dignity and the magnificence of France found expression in a distinctly French style that rivaled the more exuberant Italian form of the baroque. The history and landscape paintings of Nicolas Poussin and Claude Lorrain are characterized by symmetry and clarity of form; the artist's organization of his compositions was to demonstrate the power of reason that pervaded seventeenth-century French culture.

US in $800-bn Move To Spur Consumer Loans

In its continued fight against the economic meltdown, the US Government on Tuesday announced yet another package of a whopping $800 billion (about Rs 40 lakh crore) with a view to augmenting consumer loans by the near-bankrupt banking and mortgage institutions.This mega package is in addition to the $700-billion rescue plan, which was cleared after several rounds of intense debate in the US Congress.

The US Federal Reserve said it would buy mortgage-backed securities (MBS) worth $600 billion, which would in turn encourage lending. Further, the apex bank would launch a new facility aimed at thawing the credit market for consumers, especially in supporting issuance of auto and student loans.

In a statement on Tuesday, the US Fed announced that it would launch a programme to purchase direct obligations of housing-related Government-Sponsored Enterprises (GSEs) and mortgage-backed securities of Fannie Mae, Freddie Mac and Ginnie Mae.

The apex bank pointed out that the action was being taken to reduce cost and increase availability of credit for purchase of houses. This would, in turn, help in supporting housing markets and foster better financial market conditions.
"Purchases of up to $100 billion in GSE's direct obligations under the programme will be conducted with the Federal Reserve's primary dealers through a series of competitive auctions and will begin next week.

"Purchases of up to $500 billion in MBS will be conducted by asset managers selected via a competitive process with a goal of beginning these purchases before year-end," the US Fed noted.

Further, in a separate statement, the apex bank said it would create Term Asset-Backed Securities Loan Facility (TALF) to lend up to $200 billion, to unfreeze the credit needs of consumers and small businesses.

Lung Cancer

Also called: Bronchogenic carcinoma
Lung cancer is one of the most common cancers in the world. It is a leading cause of cancer death in men and women in the United States. Cigarette smoking causes most lung cancers. The more cigarettes you smoke per day and the earlier you started smoking, the greater your risk of lung cancer. High levels of pollution, radiation and asbestos exposure may also increase risk.

Common symptoms of lung cancer include
* A cough that doesn't go away and gets worse over time
* Constant chest pain
* Coughing up blood
* Shortness of breath, wheezing, or hoarseness
* Repeated problems with pneumonia or bronchitis
* Swelling of the neck and face
* Loss of appetite or weight loss
* Fatigue

There are many types of lung cancer. Each type of lung cancer grows and spreads in different ways and is treated differently. Treatment also depends on the stage, or how advanced it is. Treatment may include chemotherapy, radiation and surgery.

Multiple fruit

A multiple fruit is one formed from a cluster of flowers (called an inflorescence). Each flower produces a fruit, but these mature into a single mass. Examples are the pineapple, edible fig, mulberry, osage-orange, and breadfruit.In some plants, such as this noni, flowers are produced regularly along the stem and it is possible to see together examples of flowering, fruit development, and fruit ripening.

In the stages of flowering and fruit development in the noni or Indian mulberry (Morinda citrifolia) can be observed on a single branch. First an inflorescence of white flowers called a head is produced. After fertilization, each flower develops into a drupe, and as the drupes expand, they become connate (merge) into a multiple fleshy fruit called a syncarpet.

There are also many dry multiple fruits, e.g.
* Tuliptree, multiple of samaras.
* Sweet gum, multiple of capsules.
* Sycamore and teasel, multiple of achenes.
* Magnolia, multiple of follicles.

World leaders have hailed the election of Senator Barack Obama as the first black president of the United States.

UK Prime Minister Gordon Brown called Tuesday's poll historic and said he and Mr Obama "share many values".

Chinese President Hu Jintao said he looked forward to strengthening dialogue. France's Nicolas Sarkozy said the poll had raised "enormous hope".

Outgoing US President George W Bush said Mr Obama could count on "complete co-operation" during the transition.

The president-elect will take over the presidency in January.

Democratic officials quoted by the Associated Press news agency say Illinois Congressman Rahm Emanuel has been offered the job of Mr Obama's White House chief-of-staff.

Blessing

UN Secretary General Ban Ki-moon said he was looking forwards "to an era of renewed partnership and a new multilateralism".

In Kenya - the birthplace of Mr Obama's father - President Mwai Kibaki declared a national holiday on Thursday.

Pope Benedict XVI asked for "God's blessings on the American people".

The BBC's Justin Webb in Washington says Americans have made two fundamental statements about themselves - that they are profoundly unhappy with the status quo, and that they are slamming the door on the country's racial past.

At the White House, Mr Bush told reporters: "History was made yesterday."

He congratulated the president-elect on an "impressive victory" and said it represented strides "toward a more perfect union".

20th Century Drought

The Dust Bowl Drought

The Dust Bowl drought was a natural disaster that severely affected much of the United States during the 1930s. The drought came in three waves, 1934, 1936, and 1939-40, but some regions of the High Plains experienced drought conditions for as many as eight years. The "dust bowl" effect was caused by sustained drought conditions compounded by years of landPhotos from Library of Congress and U.S. National Archives management practices that left topsoil susceptible to the forces of the wind. The soil, depleted of moisture, was lifted by the wind into great clouds of dust and sand which were so thick they concealed the sun for several days at a time. They were referred to as" black blizzards".

The agricultural and economic damage devastated residents of the Great Plains. The Dust Bowl drought worsened the already severe economic crises that many Great Plains farmers faced. In the early 1930s, many farmers were trying to recover from economic losses suffered during the Great Depression. To compensate for these losses, they began to increase their crop yields. High production drove prices down, forcing farmers to keep increasing their production to pay for both their equipment and their land. When the drought hit, farmers could no longer produce enough crops to pay off loans or even pay for essential needs. Even with Federal emergency aid, many Great Plains farmers could not withstand the economic crisis of the drought. Many farmers were forced off of their land, with one in ten farms changing possession at the peak of the farm transfers.PDSI Animation, 1930s and 1950s (6 year time frame)

In the aftermath of the Dust Bowl, it was clear that many factors contributed to the severe impact of this drought. A better understanding of the interactions between the natural elements (climate, plants, and soil) and human-related elements (agricultural practices, economics, and social conditions)of the Great Plains was needed. Lessons were learned, and because of this drought, farmers adopted new cultivation methods to help control soil erosion in dry land ecosystems. Subsequent droughts in this region have had less impact due to these cultivation practices.

Indian Health & Family Welfare

India is rapidly gaining ground in the international scenario as a popular destination for foreign travelers, international students, and even for some others who opt to migrate to this mystical land for health and medical tourism. The country, which had been reeling under the onslaught of British colonial rule, managed to fight all odds and has successfully created a niche for itself. It has metamorphosed into one of the most sought after destinations for travel, much due to the presence of several renowned world heritage sites, and an inherent spiritualistic force, which pulls enthusiastic travelers towards it.

McCain Uses Biden's 'Crisis' Prediction To Question Obama

Republican running mates John McCain and Sarah Palin raised new questions about Barack Obama's readiness to lead Tuesday, taking advantage of Joe Biden's claims that Obama would face a "generated crisis."Biden's comments seemed to hand the McCain campaign yet another last-minute line of attack as the Arizona senator tries to close the gap between him and his Democratic rival in the final two weeks of the presidential campaign."We don't want a president who invites testing from the world at a time when our economy is in crisis and Americans are already fighting in two wars," McCain said Tuesday in Harrisburg, Pa. "Thanks for the warning, Joe," Palin said to cheers from about 2,500 supporters at the Reno-Sparks Convention Center in Nevada. Biden made the comments over the weekend to two fundraising audiences in Seattle, saying he expected world figures to test Obama early if he wins the election in two weeks.

"Mark my words. It will not be six months before the world tests Barack Obama like they did John Kennedy. The world is looking," Biden said. "Watch, we're gonna have an international crisis, a generated crisis, to test the mettle of this guy."The McCain campaign jumped on the remarks, with McCain and Palin bringing them up on the stump Monday evening and Tuesday. McCain on Tuesday, in response to Biden's reference to President Kennedy, recalled being ready to launch a bombing run during the October 1962 Cuban Missile Crisis."I was on board the USS Enterprise," McCain, a former naval aviator, said. "I sat in the cockpit, on the flight deck of the USS Enterprise, off of Cuba. I had a target. My friends, you know how close we came to a nuclear war." As the crowd of several thousand began to swell with cheers and applause, he added: "America will not have a president who needs to be tested. I've been tested, my friends."

Democratic aides said that Biden was merely reciting history and assuring supporters that Obama is the man for the job. But Palin on Tuesday linked Biden's comments to Obama's foreign policy positions. She said the "crisis" scenarios Biden referenced could be triggered by Obama's willingness to sit down with "the world's worst dictators," his willingness to send U.S. military into Pakistan without the approval of their government, or other positions. "But I guess the looming crisis that most worries the Obama campaign right now is Joe Biden's next speaking engagement. Let's call that crisis scenario number five," she said. The McCain campaign is trying to build steam off Biden's remark as it incorporates several other lines of attack into its day-to-day message. McCain already has gotten significant political mileage out of the man known as Joe the Plumber, who was filmed asking Obama about his tax policies two weekends ago and became the rhetorical centerpiece of the final presidential debate last week. Republicans seized on Obama's response that he would "spread the wealth around" if elected.

The McCain campaign has gone so far as to liken Obama's philosophy to "socialism." Pennsylvania Democratic Rep. John Murtha also seemed to do Republicans a favor after he called his own constituents "racist" in a newspaper interview. He later apologized and then clarified, saying some of his constituents are just "rednecks." As McCain struggles against the odds to lock down support in Obama-leaning Pennsylvania, he cited Murtha's remarks Tuesday."You may have noticed that Senator Obama's supporters have been saying some pretty nasty things about western Pennsylvania lately," he said. McCain fumbled his next line: "And you know I couldn't agree with them more." But he continued: "I could not disagree with those critics more. This is a great part of America. This is where people love their country and they serve it."

Wayne Rooney Scores Twice As England Win

Wayne Rooney scored twice as England took a giant stride towards World Cup qualification by beating Belarus to make it maximum points from four games.

Steven Gerrard gave England the lead from 30 yards after 11 minutes, but Pavel Sitko headed a deserved leveller for Belarus before the break.Rooney turned in a cross from Emile Heskey five minutes after the break.And he lifted home a superb third from Gerrard's pass 16 minutes from time to give coach Fabio Capello another win.It gives England a perfect record of 12 points so far, with Capello's huge reputation bolstered further by two convincing away wins against dangerous opposition in Croatia and Belarus.

And for Gerrard, a spectacular strike will increase his fragile self-confidence in an England shirt and silence any lingering doubts about his worth at international level.Rooney's double also demonstrated his growing maturity as he provided a deadly spearhead to the attack, ably assisted by the powerful Heskey, who was winning his 50th England cap.The Manchester United striker has now scored five goals in England's last three qualifiers as he plays a leading role in the new Capello era.Gerrard had pleaded with coach Capello to keep faith with him after a low-key display in the win against Kazakhstan - and he repaid his confidence with a stunning opener. He picked up the ball from Rooney before placing a perfect slide-rule finish into the bottom corner beyond Belarus keeper Yury Zhevnov from fully 30 yards.Instead of settling England, the goal was the signal for a period of Belarus dominance, with keeper David James having to save from Dmitry Molosh and Vitaly Kutuzov.

Heskey was working tirelessly up front to keep the Belarus defence occupied, and his fine cross set up Rooney for a far post header, but he could not find the target.Belarus were in the ascendancy, however, and it was no surprise when they drew level after 28 minutes at the end of a glorious 23-pass move.Igor Stasevich was the creator, popping up an inviting cross to the far post for Sitko to arrived unmarked and head beyond the exposed James.England needed to apply more pressure to the gifted Belarus attacking players after the break, and Rooney almost provided the perfect start with a great run that was only marred by a tame finish.He made no mistake as England regained the lead after 50 minutes, but credit must go to Heskey again with a powerful run and perfect cross for Rooney to slide home from close range.

As Belarus attempted to force their way back into contention, Capello made two changes to his attacking personnel, sending on Shaun Wright-Phillips for Theo Walcott and Peter Crouch for the excellent Heskey, who was struggling with an injury.It did not stop Rooney taking the game by the scruff of the neck and he scored his second, and England's third, with a goal of the highest class 16 minutes from time.Gerrard slid a superb instant pass into his path, and Rooney dummied a defender before lifting a composed finish over Zhevnov.The Liverpool captain should have added a fourth five minutes from time when he rounded Zhevnov, but carelessly shot again the outside of the post with the goal at his mercy.It was not a costly miss as England entered new territory by winning their opening four World Cup qualifiers for the first time.

Software engineering in China

Software is ubiquitous. It runs our businesses and controls our phones, entertainment devices, appliances, automobiles, and countless other things that humans manufacture. Even sneakers! Adidas recently announced that its latest running shoe has an embedded computer chip to adjust the shoe's performance for each individual step during a run. Although the United States now has the greatest number of companies that depend on automation, the rest of the industrial world isn't far behind. Just observe how many people in cities around the globe are walking down the street -- or worse, driving a car -- with cell phones glued to their ears.

Years ago, the term software crisis entered our everyday vocabulary because it was clear that we needed more software than we could produce. How can we keep up with the demand without sacrificing software quality?

Many companies have turned to international outsourcing, where India and Eastern Europe lead the market for software services. Both offer an educated workforce available at low cost for high-quality work. But today, another important contender is entering that marketplace: The People's Republic of China. For years, the Chinese educational system has been gearing up to meet the demand for software engineers who can compete in the global marketplace. Below, we will look at China's emergence first from the perspective of Professor Haiqing Liu of Wuhan University, a visiting scholar at Worcester Polytechnic Institute during the 2004-2005 academic year. Then, I will report what I learned from my own informal, Web-based research on the state of the Chinese software industry.

Japanese Snapping Up Wall Street Banks

Amid the U.S. financial turmoil, Japanese financial firms have been aggressive in buying assets or taking over business networks of U.S. financial institutions. Mitsubishi UFJ (MUFJ) Financial Group, Japan's second largest financial institution in terms of assets, abruptly announced it would acquire up to 20 percent in Morgan Stanley, the world's second largest investment bank.

The announcement came only a few hours after Goldman Sachs and Morgan Stanley, the last two remaining out of the five largest American investment banks, said they would turn into bank holding companies.

The takeover price will be between 400 billion yen (about W4,280 billion) and 900 billion yen (about W9,640 billion), Japanese media outlets said. MUFJ is a supersize financial group with assets of 194 trillion yen, the result of a merger of the Mitsubishi Tokyo Financial Group, Japan's second largest financial group, and UFJ Holdings, Japan's fourth largest financial firm, in 2005.

Nomura Holdings, Japan's largest securities firm, beat Barclays Group of Britain in the takeover bid for Lehman Brothers, the U.S.’ fourth largest investment bank, which has filed for bankruptcy.

This was not the first time Japanese firms have been aggressive in their bid to buy American firms. During the "bubble economy" in the late 1980s, Japanese conglomerates or large investors were busy property shopping in the U.S. and Europe. Mitsubishi Estate's purchase of the Rockefeller Center building in New York in 1989 was a symbolic incident. In a poll in the U.S. at the time, Americans said Japanese economic power was more fearsome than Soviet military power. But Japanese property shopping spree in the U.S. ended up in failure when the economic bubble burst.

Japan experienced a "lost decade" while the American economy boomed in the 1990s. But in 2007, Japanese economic growth (2.1 percent) overtook that of the U.S. (2 percent) for the first time in 15 years. Based on their restored economic power, the Japanese are back.

Cell biology

Cell biology (also called cellular biology or formerly cytology, from the Greek kytos, "container") is an academic discipline that studies cells – their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death. This is done both on a microscopic and molecular level. Cell biology research extends to both the great diversity of single-celled organisms like bacteria and the many specialized cells in multicellular organisms like humans.

Knowing the composition of cells and how cells work is fundamental to all of the biological sciences. Appreciating the similarities and also differences between cell types is particularly important to the fields of cell and molecular biology. These fundamental similarities and differences provide a unifying theme, allowing the principles learned from studying one cell type to be extrapolated and generalized to other cell types. Research in cell biology is closely related to genetics, biochemistry, molecular biology and developmental biology.

Biotechnology

Biotechnology is technology based on biology, especially when used in agriculture, food science, and medicine. The United Nations Convention on Biological Diversity defines biotechnology as:

Any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.
Biotechnology is often used to refer to genetic engineering technology of the 21st century, however the term encompasses a wider range and history of procedures for modifying biological organisms according to the needs of humanity, going back to the initial modifications of native plants into improved food crops through artificial selection and hybridization. Bioengineering is the science upon which all biotechnological applications are based. With the development of new approaches and modern techniques, traditional biotechnology industries are also acquiring new horizons enabling them to improve the quality of their products and increase the productivity of their systems.

Microbiology

Microbiology is the study of microorganisms, which are unicellular or cell-cluster microscopic organisms. This includes eukaryotes such as fungi and protists, and prokaryotes, which are bacteria and archaea. Viruses, though not strictly classed as living organisms, are also studied. In short; microbiology refers to the study of life and organisms that are too small to be seen with the naked eye.

Microbiology is a broad term which includes virology, mycology, parasitology and other branches. A microbiologist is a specialist in microbiology.

Microbiology is researched actively, and the field is advancing continually. We have probably only studied about one percent of all of the microbe species on Earth. Although microbes were first observed over three hundred years ago, the field of microbiology can be said to be in its infancy relative to older biological disciplines such as zoology and botany.

.NET Framework

The .NET Framework provides a run-time that is used to interpret intermediate code, code that is compiled from a development environment such as Microsoft’s Visual Studio when the language is C# or Visual Basic.NET. The code requires the run-time in order to execute. The code is referred to as "intermediate" because the result of the compilation is not a result that could be run at the machine level, or in other words to run without the aid of the run-time. The run-time is a service process that provides the framework for the execution of the intermediate code. The run-time acts as an interpreter of the intermediate code and then provides the structure for it to run on the operating system. Lower level capabilities it provides includes memory management, process management, and I/O management. In many cases the run-time is simply providing an abstraction level to the Windows API opening up nearly all of its capabilities to the programmer

The purpose of a run-time is to support the use rapid application development languages, such as C# and Visual Basic.NET. Highly capable run-times, such as the .NET Framework offer significant capabilities and access to the operating system and I/O. This allows a developer to create a powerful application very quickly.

Run-times are not necessarily striving for cross platform compatibility, while run-times such as Sun’s Java might.

Scripting (meta) language interpreters act similar to a run-time, although the code for many scripting languages is not pre-compiled as they are in .NET languages. Pre-compiling speeds up the act of loading the application into memory and also ensures a more compact executable file.

Google Earth Plus

Google Earth can be upgraded to a Plus edition for a $20 annual subscription fee. Google Earth Plus is an individual-oriented paid subscription upgrade to Google Earth and adds the following features:

* GPS integration: read tracks and waypoints from a GPS device. A variety of third party applications have been created which provide this functionality using the basic version of Google Earth by generating KML or KMZ files based on user-specified or user-recorded waypoints. However, Google Earth Plus provides direct support for the Magellan and Garmin product lines, which together hold a large share of the GPS market. The Linux version of the Google Earth Plus application does not include any GPS functionality.
* Higher resolution printing.
* Customer support via email.
* Data importer: read address points from CSV files; limited to 100 points/addresses. A feature allowing path and polygon annotations, which can be exported to KML, was formerly only available to Plus users, but was made free in version 4.0.2416.

Network telescope

A network telescope (also known as a darknet, internet motion sensor or black hole) is an internet system that allows one to observe different large-scale events taking place on the Internet. The basic idea is to observe traffic targeting the dark (unused) address-space of the network. Since all traffic to these addresses is suspicious, one can gain information about possible network attacks (random scanning worms, and DDoS backscatter) as well as other misconfigurations by observing it.

The resolution of the Internet telescope is dependent on the number of dark addresses it monitors. For example, a large Internet telescope that monitors traffic to 16,777,216 addresses (a /8 Internet telescope in IPv4), has a higher probability of observing a relatively small event than a smaller telescope that monitors 65,536 addresses (a /16 Internet telescope).

A variant of a network telescope is a sparse darknet, or greynet, consisting of a region of IP address space that is sparsely populated with 'darknet' addresses interspersed with active (or 'lit') IP addresses.

Wide Area Augmentation System

The Wide Area Augmentation System (WAAS) is an air navigation aid developed by the Federal Aviation Administration to augment the Global Positioning System (GPS), with the goal of improving its accuracy, integrity, and availability. Essentially, WAAS is intended to enable aircraft to rely on GPS for all phases of flight, including precision approaches to any airport within its coverage area.

WAAS uses a network of ground-based reference stations (Benchmark DGPSRs transmitting differential corrections (DCs, located within spaces protected from the public inside airportsin North America and Hawaii, to measure small variations in the GPS satellites' signals in the western hemisphere. Measurements from the reference stations are routed to master stations, which queue the received DCs and send the correction messages to geostationary WAAS satellites in a timely manner (at least every 5 seconds or better). Those satellites broadcast the correction messages back to Earth, where WAAS-enabled GPS receiver uses the corrections while computing its position to improve accuracy. The longer any given DC has been delayed, the less benefit it will produce.

The International Civil Aviation Organization (ICAO) calls this type of system a Satellite Based Augmentation System (SBAS). Europe and Asia are developing their own SBASs, the Indian Gagan, the European Geostationary Navigation Overlay Service (EGNOS) and the Japanese Multi-functional Satellite Augmentation System (MSAS), respectively. Commercial systems include StarFire and OmniSTAR.

Database transaction

A database transaction is a unit of work performed against a database management system or similar system that is treated in a coherent and reliable way independent of other transactions. A database transaction, by definition, must be atomic, consistent, isolated and durable. These properties of database transactions are often referred to by the acronym ACID.

Transactions provide an "all-or-nothing" proposition stating that work units performed in a database must be completed in their entirety or take no effect whatsoever. Further, transactions must be isolated from other transactions, results must conform to existing constraints in the database and transactions that complete successfully must be committed to durable storage.

Wednesday, July 16, 2008

Transaction processing system

A 'Transaction Processing SystemTo be considered a transaction processing system the computer must pass the ACID test.

From a technical perspective, a Transaction Processing System (or Transaction Processing Monitor) monitors transaction programs, a special kind of programs. The essence of a transaction program is that it manages data that must be left in a consistent state. E.g. if an electronic payment is made, the amount must be either both withdrawn from one account and added to the other, or none at all. In case of a failure preventing transaction completion, the partially executed transaction must be 'rolled back' by the TPS. While this type of integrity must be provided also for batch transaction processing, it is particularly important for online processing: if e.g. an airline seat reservation system is accessed by multiple operators, after an empty seat inquiry, the seat reservation data must be locked until the reservation is made, otherwise another user may get the impression a seat is still free while it is actually being booked at the time. Without proper transaction monitoring, double bookings may occur. Other transaction monitor functions include deadlock detection and resolution (deadlocks may be inevitable in certain cases of cross-dependence on data), and transaction logging (in 'journals') for 'forward recovery' in case of massive failures.

Transaction Processing is not limited to application programs. The 'journaled file system' provided with IBMs AIX Unix operating system employs similar techniques to maintain file system integrity, including a journal.

Hierarchical model

In a hierarchical data model, data is organized into a tree-like structure. The structure allows repeating information using parent/child relationships: each parent can have many children but each child only has one parent. All attributes of a specific record are listed under an entity type. In a database, an entity type is the equivalent of a table; each individual record is represented as a row and an attribute as a column. Entity types are related to each other using 1: N mapping, also known as one-to-many relationships. The most recognized example of hierarchical model database is an IMS designed by IBM.

Encryption of mail sessions

All relevant email protocols have an option to encrypt the whole session. Remarkably, those options prevent a user's name and password from being sniffed, therefore they are recommended for nomadic users and whenever the internet access provider is not trusted. On sending mail, users can only control encryption at the hop from a client to its configured outgoing mail server. At any further hop, messages may be transmitted with or without encryption, depending solely on the general configuration of the transmitting server and the capabilities of the receiving one.

Encrypted mail sessions deliver messages in their original format, i.e. plain text or encrypted body, on a user's local mailbox and on the destination server's. The latter server is operated by an email hosting service provider, possibly a different entity than the internet access provider currently at hand.

AntiVirus Gold

AntiVirus Gold is a piece of rogue software that poses as a legitimate antivirus program. It is typified by a small icon in the system tray, with a link directing to download the offending software. It could also possibly do a homepage hijack. There have also been many variants of this malware, such as Antivirus Golden, Antispyware Gold and the like. They seem to be related to both WinAntiVirus and Winfixer. Typically, said infections are installed by the Vundo, SysProtect or SmitFraud trojans.

Gathering of addresses

In order to send spam, spammers need to obtain the e-mail addresses of the intended recipients. To this end, both spammers themselves and list merchants gather huge lists of potential e-mail addresses. Since spam is, by definition, unsolicited, this address harvesting is done without the consent (and sometimes against the expressed will) of the address owners. As a consequence, spammers' address lists are inaccurate. A single spam run may target tens of millions of possible addresses — many of which are invalid, malformed, or undeliverable.

Sometimes, if the sent spam is "bounced" or sent back to the sender by various programs that eliminate spam, or if the recipient clicks on an unsubscribe link, that may cause that email address to be marked as "valid", which is interpreted by the spammer as "send me more".

Adaptive system

An adaptive system is a system that is able to adapt its behavior according to changes in its environment or in parts of the system itself. A human being, for instance, is certainly an adaptive system; so are organizations and families. Some man-made systems can be made adaptive as well; for instance, control systems utilize feedback loops in order to sense conditions in their environment and adapt accordingly. Robots incorporate many of these control systems. Neural Networks are a common type of algorithmic implementation of adaptive systems.

Diffusion of innovations theory can help to explain the uptake of new ideas, practices and products by individuals and social groups -- human adaptive systems.

Systems engineering

Systems engineering is an interdisciplinary field of engineering, that focuses on the development and organization of complex artificial systems. Systems engineering is defined by INCOSE as "a branch of engineering whose responsibility is creating and executing an interdisciplinary process to ensure that customer and stakeholder's needs are satisfied in a high quality, trustworthy, cost efficient and schedule compliant manner throughout a system's entire life cycle, from development to operation to disposal. This process is usually comprised of the following seven tasks: State the problem, Investigate alternatives, Model the system, Integrate, Launch the system, Assess performance, and Re-evaluate. The systems engineering process is not sequential: the tasks are performed in a parallel and iterative manner."

Systems intelligence

Systems intelligence is human action that connects sensitivity about a systemic environment with systems thinking, thus spurring a persons problem solving capabilities and invoking performance and productivity in everyday situations. Systems intelligence, abbreviated SI, is intelligent behavior in complex systems, that are often human in nature. Key concepts a person uses when acting systems intelligently are perception of systemic occurrencies, feedback from the system's structure and interaction with the system's agents and subsystems.

Types of systems psychology

In the scientific literature different kind of systems psychology have been mentioned in the scientific literature:

Applied systems psychology
De Greene in 1970 described applied systems psychology as being connected with engineering psychology and human factor.

Cognitive systems theory
Cognitive systems psychology is a part of cognitive psychology and like existential psychology, attempts to dissolve the barrier between conscious and the unconscious mind.

Contract-systems psychology
Contract-systems psychology is about the human systems actualization through praticipative organizations.

Family systems psychology
Family systems psychology is a more general name for the subfield of family thearpists and like Murray Bowen, Michael E. Kerr, and Baard. and researchers have begun to theoretize a psychology of the family as a system.

Organismic-systems psychology
Through the application of organismic-systems biology to human behavior Ludwig von Bertalanffy conceived and developed the organismic-systems psychology, as the theoretical prospect needed for the gradual comprehension of the various ways human personalities may evolve and how could they evolve properly, being supported by a holistic interpretation of human behavior.

Developmental robotics

Developmental Robotics (DevRob), sometimes called epigenetic robotics, is a methodology that uses metaphors from developmental psychology to develop controllers for autonomous robots. The focus is on a single robot going through stages of autonomous mental development. Researchers in this field study artificial emotions, self-motivation, and other methods of self-organization.

DevRob is related to, but differs from, evolutionary robotics (ER). ER uses populations of robots that evolve over time, whereas DevRob is interested in how the organization of a single robot's control system develops through experience, over time.

DevRob is also related to work done in the domains of Robotics, Artificial Life.

Similar to developmental robotics, Epigenetic robotics is an interdisciplinary research area with the goal of understanding biological systems by the integration between neuroscience, developmental psychology and engineering sciences. Epigenetic systems are characterized by a prolonged developmental process through which varied and complex cognitive and perceptual structures emerge as a result of the interaction of an embodied system with a physical and social environment. An additional goal is to enable robots to autonomously develop skills for any particular environment instead of programming them for a specific environment.

Islamic Golden Age

The Islamic Golden Age, also sometimes known as the Islamic Renaissance, is traditionally dated from the 8th century to the 13th century, though some have extended it to the 15th or 16th centuries. During this period, engineers, scholars and traders in the Islamic world contributed to the arts, agriculture, economics, industry, law, literature, navigation, philosophy, sciences, and technology, both by preserving and building upon earlier traditions and by adding inventions and innovations of their own. Howard R. Turner writes: "Muslim artists and scientists, princes and laborers together created a unique culture that has directly and indirectly influenced societies on every continent."

Cargo

Cargo is a term used to denote goods or produce being transported generally for commercial gain, usually on a ship, plane, train, van or truck. Nowadays containers are used in most intermodal long-haul cargo transport.

Cargo represents a concern to U.S. national security. It was reported out of Washington, DC that in 2003 over 6 million cargo containers are entering the United States each year. After the terrorist attacks of September 11th, the security of this magnitude of cargo has become highlighted. The latest US Government response to this threat is the CSI: Container Security Initiative. CSI is a program intended to help increase security for containerized cargo shipped to the United States from around the world.

Pre-Columbian Islamic contact theories

Pre-Columbian Islamic contact theories are theories which contend that medieval Muslim explorers from the Islamic world (specifically Al-Andalus, Africa or China) may have reached the Americas (and possibly made contact with the indigenous peoples of the Americas) at some point before Christopher Columbus' first voyage to the Americas in 1492. Proponents of these theories cite as evidence reports of expeditions and voyages conducted by Muslim navigators and adventurers who they allege reached the Americas from the late 9th century onwards

Prototyping

Prototyping is the process of quickly putting together a working model (a prototype) in order to test various aspects of a design, illustrate ideas or features and gather early user feedback. Prototyping is often treated as an integral part of the system design process, where it is believed to reduce project risk and cost. Often one or more prototypes are made in a process of iterative and incremental development where each prototype is influenced by the performance of previous designs, in this way problems or deficiencies in design can be corrected. When the prototype is sufficiently refined and meets the functionality, robustness, manufacturability and other design goals, the product is ready for production.

Object database

In an object oriented database, information is represented in the form of objects as used in object-oriented programming. When database capabilities are combined with object programming language capabilities, the result is an object database management system (ODBMS). An ODBMS makes database objects appear as programming language objects in one or more object programming languages. An ODBMS extends the programming language with transparently persistent data, concurrency control, data recovery, associative queries, and other capabilities.

Database security

Database security is the system, processes, and procedures that protect a database from unintended activity. Unintended activity can be categorized as authenticated misuse, malicious attacks or inadvertent mistakes made by authorized individuals or processes. Database security is also a specialty within the broader discipline of computer security.

Traditionally databases have been protected from external connections by firewalls or routers on the network perimeter with the database environment existing on the internal network opposed to being located within a demilitarized zone. Additional network security devices that detect and alert on malicious database protocol traffic include network intrusion detection systems along with host-based intrusion detection systems.

Proxy server

In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it would 'cache' the first request to the remote server, so it could save the information for later, and make everything as fast as possible.

SQL (Structured Query Language)

SQL (Structured Query Language) (pronounced /ɛskjuːˈɛl/ officially, although the unofficial pronunciation /ˈsiːkwəl/ is often used (see below)) is a database computer language designed for the retrieval and management of data in relational database management systems (RDBMS), database schema creation and modification, and database object access control management.

SQL is a standard interactive and programming language for querying and modifying data and managing databases. Although SQL is both an ANSI and an ISO standard, many database products support SQL with proprietary extensions to the standard language.

Toxicity of Metabolites

Many substances regarded as poisons are toxic only indirectly. An example is "wood alcohol," or methanol, which is chemically converted to formaldehyde and formic acid in the liver. It is the formaldehyde and formic acid that cause the toxic effects of methanol exposure. Many drug molecules are made toxic in the liver, a good example being acetaminophen (paracetamol), especially in the presence of alcohol. The genetic variability of certain liver enzymes makes the toxicity of many compounds differ between one individual and the next. Because demands placed on one liver enzyme can induce activity in another, many molecules become toxic only in combination with others.

Human-powered transport

Human-powered transport is the transport of person(s) and/or goods using human muscle power. Like animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming. Modern technology has allowed machines to enhance human-power.

Although motorization has increased speed and load capacity, many forms of human-powered transport remain popular for reasons of lower cost, leisure, physical exercise and environmentalism. Human-powered transport is sometimes the only type available (especially in underdeveloped or inaccessible regions), and is considered an ideal form of sustainable transportation.

Computer Printer

A computer printer, or more usually a printer, produces a tough copy (permanent human-readable text and/or graphics) of documents stored in electronic form, generally on physical print media such as paper or transparencies. Many printers are mostly used as local computer peripherals, and are attached by a printer cable to a computer which serves as a text source. Some printers, commonly known as network printers, have built-in network interfaces (typically wireless or Ethernet), and can offer as a hardcopy device for any customer on the network. Individual printers are often planned to support both local and network linked users at the same time.

In addition, many modern printers can straight interface to electronic media such as memory sticks or memory cards, or to image capture devices such as digital cameras, scanners; some printers are combined with a scanners and/or fax machines in a single unit. Printers that contain non-printing features are sometimes called Multi-Function Printers (MFP) or Multi-Function Devices (MFD).

British coinage

Obverse and overturn of universal coins in existing circulation, £2, £1, 50p, 20p, 10p, 5p, 2p and 1pThe British money was decimalised on February 15, 1971. The fundamental unit of currency – the Pound was unchanged. Before decimalization there were 240 (old) pennies in a pound, at present there are 100 new pence. The new coins were visible with the wording "New Penny" (singular) or "New Pence" (plural) to differentiate them from the old. The word New was dropped following ten years. The symbol p was also adopted to distinguish the new pennies from the old, which used the symbol d.

The first pound coin was introduced in 1983 to replace the Bank of England £1 banknote which was discontinued in 1984 (although the Scottish banks continued producing them for some time afterwards. The last of them, the Royal Bank of Scotland £1 note, remained in production until 2003). A circulating bimetallic £2 coin was also introduced in 1998 (first minted in, and dated, 1997) – there had before been commemorative £2 coins which did not normally circulate. The whole quantity of coinage in circulation is approximately three and a quarter billion pounds, of which the £1 and £2 coins account for almost two billion pounds.

Sustainable Transportation

Sustainable transportation concerns systems, policies, and technologies. It aims for the efficient transit of goods and serivces, and sustainable freight and delivery systems. The design of vehicle-free city planning, along with pedestrian and bicycle frendly design of neighbourhoods is a critical aspect for grassroots activities, as are telework and teleconferencing.

Football (soccer)

Association football, commonly known as football or soccer, is a team sport played between two teams of eleven players, and it is the most fashionable sport in the world. It is a ball game played on a rectangular grass or artificial turf field, with a goal at each of the short ends. The purpose of the game is to score by manoeuvring the ball into the opposing goal. In general play, the goalkeeper is the only player permitted to use their hands or arms to propel the ball; the rest of the team usually use their feet to kick the ball into position, occasionally using their torso or head to intercept a ball in mid air. The team that scores the most goals by the end of the match wins. If the score is tied at the end of the game, either a draw is declared or the game goes into extra time and/or a penalty shootout, depending on the format of the competition.
The modern game was codified in England following the formation of The Football Association, whose 1863 Laws of the Game created the foundations for the way the sport is played today. Football is governed internationally by the Federation Internationale de Football Association (International Federation of Association Football), commonly known by the acronym FIFA. The most prestigious international football competition is the World Cup, held every four years. This event, the most widely viewed in the world, boasts an audience twice that of the Summer Olympics.

Uses of Ginger

There are array of uses suggested for ginger. A tea brewed from the is a folk medicine for colds. Ginger ale and ginger beer have been suggested as "stomach settlers" for generation in countries where the beverages are made and ginger water was commonly used to avoid heat cramps in the US. Ginger has also been historically used to take care of inflammation which some scientific studies support, though one arthritis trial showed ginger to be no better than a placebo or ibuprofen. Research on rats suggests that ginger may be valuable for treating diabetes.

Cricket in India

without doubt the first sport that comes to mind when one thinks of Indian sports today is cricket. Brought to India by her British colonisers, cricket so captured the nation’s thoughts that observers are more or less agreed that today it is the one religion that unites India.
In cities like Calcutta, with everybody glued to their TV sets, life grinds to a stop the progress of the days the Indian team is playing. One-day gear and test matches stimulate equal eagerness; for together, if the match is being played on Indian earth, which by the way supports spin slightly than pace, you’ll get aptitude crowds and a emotional atmosphere seldom matched anywhere outside the subcontinent. Allegations of murky match fixing and a fixed string of matches where the team managed to “grab defeat from the jaws of victory” notwithstanding, the attractiveness of the game continues to rise. Such is the strength of participation with the game that it even affects India’s international relationships. In the result of the 1999 Kargil war, India unilaterally overhanging cricketing relations with Pakistan. The discuss on whether politics and sports should mix enlivens many a discussion, and is yet unresolved.

Abraham Lincoln

The brave man of the familiar People. It had been an extended time coming. Terribly separated by the issue of slavery, thirty-one million American citizens were in 1860
Called upon to vote for 16th President of the United States. The Democratic Party meets at its National Party Convention in Charleston, South Carolina, in order to choose their candidate in favor of the presidency. Split over slavery, each section, Northern Democrats on the one hand and Southern Democrats on the other, presented its own conflicting proposal for the party platform.
In February 1860, Senator Jefferson Davis of Mississippi claimed that neither the Congress of the United States nor the territorial parliaments had the control to handle slavery.

Adam Sandler: the Funniest man Alive!

With a hazardous brand of humor that has brought him legions of dedicated fans, Sandler's hit as an actor, stand-up comic, writer and producer is matched by his performance and songwriting skills. It is an shocking gift for lyric and melody that is front and center on Adam Sandler's very funny new Warner Bros. Records release What is Your surname featuring 14 new Sandler originals include such classics as The Goat Song, the Lonesome Kicker, Bad Boyfriend and Corduroy Blues.
What is Your Name continues the musical tradition Sandler began with at a standard Pace, Ode to My Carnd the extremely popular The Chanukah Song. With two platinum-selling, Grammy-nominated albums - They're All Gonna Laugh at you and What the Hell Happened to Me - Already to his credit, Sandler goes for a comedy-three peat with what’s Your Name. The move to an all-music format is a normal one, following his 21 city tour last summer, when he perform both creative material and his favorite childhood tunes, backed by a finest rock and roll band.

The Banyan Tree

In India the Banyan Tree is consider as National tree. This huge tree overlooks over its neighbors and has the widest reaching roots of all known trees, easily covering several acres. It sends off new shoots from its roots, so that one tree is really a interweave of branches, roots, and trunks. The banyan tree restart and lives for an incredible length of time--thus it is thought of as the everlasting tree.

Its size and leafy shelter are valued in India as a place of relax and mirror image, not to mention defense from the hot sun! It is still the focus and gathering place for local councils and meetings. India has a long history of worship this tree; it figures importantly in many of the oldest stories of the nation.

A Team Player

The superiority of being a team player is one that everyone should enjoy. A team player is someone with good qualities who makes contributions and has the force to motivate each one around him or her. This individuality can be used in many areas such as games, family life, and in the company. You are more expected to be hired in the production if you have and demonstrate the qualities of a team player. As the business climate gets tougher before it gets improved, it is time to hike the talk if you want to develop.

Managers will require all the cooperation they can get. To land a high paying job with a major business you need to be a team player. Having good qualities is one of the most significant characters you can have. Being a team performer thinks of the team as a whole and is not selfish in their views and decisions.

A Snapshot of Macro-Economics

Economics is the learning of making choices. High school and college students all over required to take economic courses in order to achieve a diploma. Why is economics so important because it provides a guide for students for real-world situations Economics is divided into two types microeconomics and macroeconomics. Microeconomics is the study of economics at a slim level. For example absorbed on how a detailed business functions is microeconomics.
Studying the world economy is classified as Macroeconomics; its center on a much broader level. All students must understand the concept of insufficiency. Scarcity is a condition that occurs because society has unlimited wants and needs however the amount of property is limited. Unlimited wants and needs are what encourage us to create goods and services. We are never satisfied therefore we always have a want or need. On the other hand our income is limited.

A simple Girl

Around and around it soared in brutal circles, tearing from side to side her animated temples. At a standstill, they did not do anything. Still, they simply laid there with faces of chalk, invalid of all human emotions. She could not look at them in hopes of relieve, for long. The cherry rivers that flowed across her eyes, streamed down her steaming cheeks, made vision impossible.
Life was simply the stack of decayed flesh that enclosed her. From his immortal lips hung the bodies of all those who died struggle for him and all those who had tampered with self luxury. For that, she dammed him for all eternity; in every form he understood she dammed him. He had been her guiding angle and now it became evident to her. No prayer would pass her conditions lips, for this had been his movement she had fought and they had lost other than just a clash.

A Civil Role Model

The word civil carries a lot of power. The usage needs to be carefully considered when it's entered into a sentence or an expression. Civil means a wide difference of things. It can be defined as a way to be attentive of the forms required for good reproduction. It can also be a means to the needs and affairs of the common public. However, the latter of the two definitions can also be extended to include a definition of the private rights and the remedy sought by action or costume. The point is that the word civil has a greater significance that has been embraced by our American legal traditions. It is the premise that law is there to provide the people and the lawyers are nothing more than mere guardians of law.

These are thoughts that were measured during the class viewing of A Civil Action. In the events of the case, there were many concerns that were brought up about our permissible culture.

A cold winter morning

I am lying on a white, sandy beach with the glowing sun beating down directly on my tanned summer body. I notice the beautiful, Puerto Rican Cabana boy heading over to replenish my newly empty Margarita glass. I look around my private beach and at the crystal clear, sparkling ocean water tempting me warmly in to its open arms. I get up from my bed on the sand, walking gradually to the water. The sand is flaming my bare feet with such passion that I speed my walk up almost into a jog. As I reach the waterfront I stop, as a falling wave is heading toward my glazing body; I step closer to be in its direct path. I move smoothly in with such grace; I prepare myself for the cool, refreshing bath. I hear an alarm bell screaming, I look around in a panic as it is hurting my ears and giving me a powerful headache. My beach is wandering away, and then it is gone. The ‘warmness my body feels is gone.
I open my eyes; I am gloomy, lifeless room. My alarm clock is going off and the sound can only be compared with exhausted your fingernails across a chalkboard.

Java

Java (Javanese, Indonesian, and Sundanese: Jawa) is an land mass of Indonesia and the place of its capital city, Jakarta. Once the centre of controlling Hindu kingdoms and the heart of the colonial Dutch East Indies, Java now plays a governing role in the money-making and supporting life of Indonesia. With a population of 124 million, it is the most heavily populated island in the world; it is also one of the most thickly populated regions on Earth.

Java shaped mostly as the result of volcanic events, Java is the 13th leading island in the world and the fifth major island of Indonesia. A sequence of volcanic mountains forms an east-west spine along the island. It has three main languages, and most populace are bilingual, with Indonesian as their second language. While the popular of Javanese are Muslim (or at least supposedly Muslim), Java has a different mixture of religious beliefs and cultures.

Java Coffee

Java coffee is a coffee bent on the island of Java. In the USA, the term "Java" independently is slang for coffee generally. The Indonesian phrase Kopi Jawa refers not only to the origin of the coffee, but is used to distinguish the black, very sweet coffee, strong with powdered grains in the drink, from other forms of the drink.The Dutch began farming of coffee trees on Java (part of the Dutch East Indies) in the 17th century and it has been export internationally since. The coffee farming systems found on Java have changed significantly over time.

A rust disease in the late 1880s killed off much of the plantation stocks in Sukabumi, before distribution to Central Java and parts of East Java. The Dutch respond by replacing the Arabica firstly with Liberica (a tough, but somewhat unpleasant coffee) and later with Robusta. Today Java's old royally era plantations provide just a portion of the coffee grown on the island. Logo of Java programming language is a coffee cup.

Turmeric

Turmeric (Curcuma longa) is a rhizomatous herbaceous continuing plant of the ginger family, Zingiberaceae which is citizen to tropical South Asia. It wants temperatures between 20 and 30 deg. C. and a significant amount of annual rainfall to succeed. Plants are gathered yearly for their rhizomes, and re-seeded from some of those rhizomes in the following season.It is also often pronounced as tumeric. It’s name vary according to region, in some Asian countries as kunyit.

Its rhizomes are boil for several hours and then dried in hot ovens, after which they are position into a deep orange-yellow powder generally used as a flavor in curries and for dyeing, other South Asian cuisine, and to impart color to mustard condiments. Its active component is curcumin and it has an bitter, earthy, peppery flavor.Sangli, a town in the southern part of the Indian state of Maharashtra, is the largest and most important trade centre for turmeric in Asia or maybe in the entire world.

Sport

Sport is a movement that governs by a set of regulations or rules and frequently engaged in competition. Used by itself, sports usually refer to behavior where the physical capability of the participant are the sole or primary determiner of the outcome (winning or losing), but the term is also used to include behavior such as brainpower sports and cruise sports where mental acuity or apparatus quality are major factors. Sports are used as amusement for the player and the viewer. It has also been established by experiments that daily exercise increases mental strength and power to study.

Keeping pace with the latest sports results is a usual appliance for Semotus wireless technology.

Fashionable watches

At the end of the 20th century, Swiss watch makers were seeing their sales go down as analog clocks were considered unfashionable. They joined forces with designers from many countries to reinvent the Swiss watch. The result was that they could considerably decrease the pieces and production time of an analog watch. In fact it was so cheap that if a watch broke it would be cheaper to fling it away and buy a new one than to repair it. One of these Swiss watch manufacturers in progress a new brand, Swatch, and called graphic designers to revamp a new annual collection.

Light Arrester

In telegraphy and telephony a lightning arrester is to be found where wires enter a structure, preventing harm to electronic instruments within and ensuring the protection of individuals near them. Lightning arresters, also called rush protector, are devices which are linked between each electrical conductor in a power and transportation systems and the earth. These provide a short circuit to the earth that is interrupted by a non-conductor over which lightning jumps. Its function is to limit the rise in voltage when a connections or power line is struck by lightning.

The non-conducting substance may consist of a semi-conducting material like silicon carbide or zinc oxide, or a spark gap. Primitive varieties of such flash gaps are simply open to the air, but more modern varieties are filled with dry gas and provided with a little amount of radioactive material to support the gas to ionize when the voltage across the gap reaches a particular level. Other designs of lightning arresters use a glow-discharge tube associated between the protected conductor and ground, or any one of a many of voltage-activated solid-state switches called varistors or MOV's. Lightning arresters built for substation use are consisting of a porcelain tube several feet in length and several inches in diameter, impressive devices, fill with disks of zinc oxide. A safety port is full on the side of the device to vent the occasional internal explosion without shocking the porcelain cylinder.

Hardware

Hardware is the general name that is used to express physical body of a technology.It can be apparatus such as keys, hinge, locks, latches, wire, handles, corners, shackles, plumbing supplies, tools, cutlery, utensils, and machine parts, mainly when they are made of metal. In the United States, hardware has been customarily sold in hardware stores.

Although often used interchangeably to mean "hand tools," hardware in olden times referred to the metal bits that were used to make wooden products stronger, more useful, and easier to build/assemble than if they did not have the benefit of metal fittings.In a looser logic, hardware can be a major military equipment, or electronic equipment, or computer equipment. On the other hand, people don't talk about computer stores as "hardware supplies".

In vernacular context, the term refers to trophies and other physical representations of award. The term "hardware" is used to specifically mean material or tangible parts of the computer when used in the context of computer systems and when compared to non-physical software running on the computer. Example: the CPU

Love

Love is a constellation of feelings and experiences associated to a sense of strong liking or profound oneness. The meaning of love differs relative to context. Romantic love is seen as an inexpressible feeling of strong attraction shared in passionate or intimate attraction and intimate interpersonal and sexual relationships. Though often associated to personal relations, love is time and again given a wider connection, a love of humanity, with life itself, of nature, or an oneness with the universe, a worldwide love or karma. Love can as well be construed as Platonic love, familial love, religious love, and, more indifferently, great liking for anything measured strongly pleasurable, pleasing, or preferred, to include activities and foods. This diverse range of meanings in the outstanding word love is often contrasted with the plurality of Greek words for love, reflecting the concept's profundity, versatility, and complexity.

Management information system

Management Information Systems (MIS) is a general name for the educational discipline casing the application of people, technologies, and procedures —together called information systems — to solve business problems. MIS are distinctive from normal information systems in that they are used to evaluate other information systems applied in operational activities in the organization. Rationally, the term is commonly used to refer to the group of information management methods attached to the automation or support of human decision making, e.g. Decision Support Systems, Expert systems, and Executive information system

Accumulator

In a computer CPU, an accumulator is a register in which intermediary arithmetic and logic results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, possibly only to be read right back again for use in the next operation. Access to main memory is slower than access to a register like the accumulator because the technology used for the huge main memory is slower (but cheaper) than that used for a register.

The canonical example for accumulator use is adding a list of numbers. The accumulator is initially set to zero, then each number in spin is added to the value in the accumulator. Only when all numbers have been added is the result seized in the accumulator written to main memory or to another, non-accumulator, CPU register.

Superscalar

A superscalar CPU architecture implements a form of parallelism called Instruction-level parallelism within a solitary processor. It thereby allows faster CPU throughput than would otherwise be possible at the same clock rate. A superscalar architecture executes more than one instruction during a single pipeline stage by pre-fetching several instructions and at the same time dispatching them to redundant functional units on the processor.

History

Seymour Cray's CDC 6600 from 1965 is often mentioned as the first superscalar plan. The Intel i960CA and the AMD 29000-series 29050 microprocessors were the first commercial single-chip superscalar microprocessors. RISC CPUs like these brought the superscalar idea to micro computers because the RISC design results in a simple core, allowing straightforward instruction send off and the inclusion of multiple functional units on a single CPU in the inhibited design rules of the time. This was the reason that RISC designs were faster than CISC designs through the 1980s and into the 1990s.

Neem oil

Neem oil is a vegetable oil pressed from the fruits and seeds of Neem, an evergreen tree which is endemic to the Indian sub-continent and has been introduced to many other areas in the tropics. It is perhaps the most significant of the commercially available products of neem.
Neem oil is typically light to dark brown, bitter and has a rather strong odour that is said to join the odours of peanut and garlic. It comprises mainly triglycerides and large amounts of triterpenoid compounds, which are in charge for the bitter taste. It is hydrophobic in nature and in order to emulisify it in water for application purposes, it must be formulated with suitable surfactants.
Neem oil also contains steroids and a plethora of triterpenoids of which Azadirachtin is the most well known and studied. The Azadirachtin content of Neem Oil varies from 300ppm to over 2000ppm depending on the quality of the neem seeds compressed.

Swan

Swans are large water birds of the family Anatidae, which also includes geese and ducks. Swans are grouped with the intimately related geese in the subfamily Anserinae where they form the tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae.

Swans typically mate for life, though "divorce" does sometimes occur, mainly following nesting failure. The number of eggs in each clutch is between 3–8.
The word is derived from Old English swan, akin to German Schwan, in turn derived from Indo-European root *swen (to sound, to sing), whence Latin derives sonus (sound). Young swans are known as cygnets, from the Latin word for swan, cygnus. An adult male is a cob, from Middle English cobbe; an adult female is a pen .

Ice

Ice is the name given to any one of the 14 known solid phases of water. Though in non-scientific contexts, it usually describes ice Ih, which is the most abundant of these phases. It is a crystalline solid, which can appear transparent or an opaque bluish-white color depending on the presence of impurities such as air. The addition of other materials such as soil may further alter appearance. The most common phase transition to ice Ih occurs when liquid water is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure. However, it can also deposit from a vapor with no intervening liquid phase such as in the formation of frost. Ice appears in varied forms such as hail, ice cubes, and glaciers. It plays an important role with many meteorological phenomena. The ice caps of the polar regions are of significance for the global climate and particularly the water cycle.

Shrimp fishery

A shrimp fishery is a fishery directed toward harvesting either shrimp or prawns. Fisheries do not usually differentiate between the two taxa, and the terms are used interchangeably. This article therefore refers to the catching of either shrimp or prawns.

A number of the larger species, including the Atlantic white shrimp (Penaeus setiferus), are caught commercially and used for food. Recipes utilizing shrimp form part of the cuisine of many cultures: examples include jambalaya, okonomiyaki, poon choi, bagoong, Kerala and scampi.
Preparing shrimp for consumption usually involves removing the shell, tail, and "sand vein". As with other seafood, shrimp is high in calcium, protein and low in food energy.
Shrimp and prawns are versatile ingredients, and are often used as an accompaniment to fried rice. Common methods of preparation comprise baking, boiling and frying. As stated in the movie Forrest Gump

Rose

A rose is a flowering shrub of the genus Rosa, and the flower of this shrub. There are more than a hundred classes of wild roses, all from the northern hemisphere and typically from temperate regions. The species form a group of normally prickly shrubs or climbers, and sometimes trailing plants, reaching 2–5 m tall, hardly ever reaching as high as 20 m by climbing over other plants.
Rose hips are sometimes eaten, mostly for their vitamin C content. They are typically pressed and filtered to make rose-hip syrup, as the fine hairs surrounding the seeds are unpleasant to eat. They can also be used to create herbal tea, jam, jelly and marmalade.

Industrial metal

Industrial metal is a musical genre which draws elements from industrial music and heavy metal music. Industrial metal music is typically centered around metal guitar riffs and industrial synthesizer/sequencer lines, heavily distorted, very low pitched guitars, as well as harsh vocals, but in some instances can have clean vocals. This term is used quite loosely, telling everything from industrial bands sampling metal riffs to heavy metal groups augmented with sequencers. Industrial metal encompasses industrial subgenres such as aggro-industrial and coldwave and often overlaps some elements of nu-metal and post-punk.

It is difficult to distinguish many industrial metal artists and industrial rock because both genres leave much room for ingenuity and creativity. By convention, all industrial metal artists may be more vaguely described as industrial rock as well, but not all industrial rock artists are properly described as industrial metal. The general rule of thumb is the speed and "crunchiness" of the guitars. If the guitars are fast and heavily distorted, it is likely industrial metal.

Genetics

Genetics is the science of heredity and variation in living organisms.Knowledge that desired characteristics were present at birth has been implicitly used since prehistoric times for improving crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the mechanisms of inheritance, only began with the work of Gregor Mendel in the mid-1800s.

Mendel observed that inheritance is basically a discrete process with specific traits that are inherited in an independant manner. These basic units of inheritance is now known as "genes". In the cells of organisms, genes exist actually in the structure of the molecule DNA and the information genes contain is used to create and control the components of cells. Although genetics plays a large role in determining the appearance and behavior of organisms, it is the interaction of genetics with the environment an organism experiences that determines the ultimate outcome. For example, while genes play a role in determining a person's height, the nutrition and health that person experiences in childhood also have a large effect.
