The uses for oil

Oil is the largest source of liquid fuel and, in spite of attempts to develop synthetic fuels, world consumption of oil products in increasing.
The oil industry is not much more than a hundred years old. It began when the first oil well was drilled in 1859. In the early days, oil was used to light houses because there was no electricity and gas was very scarce. Later, people began to use oil for heating too.
Most industries use machinery to make things. Every machine needs oil in order to run easily. Even a small clock or watch needs a little oil from time to time.
The engines of many machines use oil fuels petrol, kerosene or diesel. Cars, buses, trucks, tractors, and small aircraft use petroleum chemicals: synthetic rubber, plastics, synthetic fiber materials for clothes and for the home, paints, materials which help to stop rust, photographic materials, soap and cleaning materials (detergents), drugs, fertilizers for farms and gardens, food containers, and may others.
In 1900 the world’s oil production was less than 2 million tons a year. Today the oil industry is one of the world’s largest and most important suppliers of raw materials.

                                    When was the first computer unvented?

            The word "computer" was first recorded as being used in 1613 and was originally used to describe a human who performed calculations or computations. The definition of a computer remained the same until the end of the 19th century when people began to realize machines never get tired and can perform calculations much faster and more accurately than any team of human computers ever could.
            In 1822, Charles Babbage began developing the Difference Engine, which was considered to be the first automatic computing engine. It was capable of computing several sets of numbers and making hard copies of the results. Unfortunately, because of funding he was never able to complete a full-scale functional version of this machine. In June of 1991, the London Science Museum completed the Difference Engine Nº 2 for the bicentenni- al year of Babbage"s birth and later completed the printing mechanism in 2000.

UN announces program to help hunger hot spots

A UN agency rolled out a $ 214 million program Tuesday to help 16 needy places hit hard by high prices for food and oil, amid a crisis already making it hard for aid groups to provide enough food for the worlds hungry.

The World Food Program said almost 1 billion poor people around the world are struggling to survive amid the higher prices. The agency is trying to reach those in critical need of assistance in Africa, Asia and the Caribbean.

"Food prices are not abating, and the worlds most vulnerable have exhausted their coping strategies", said Josette Sheeran, the agencys executive director. "Our action plan is targeted and customized to help the most vulnerable meet their urgent needs.
"The plan will provide assistance to groups such as pregnant women, undernourished children and people living in urban areas affected most by the food crisis.

The Rome-based agency also hopes to cut transportation costs and help support farmers in countries where emergency food can be bought locally.

But the agency already faces "obstacles" in procuring food, particularly when trying to buy supplies locally, spokeswoman Brenda Barton said.
"At the markets we have been buying food it has become just too expensive", Barton told The Associated Press by telephone. And she added: "a lot of markets just dont have any food to buy."

How to dig out from the information avalanche
Majority of workers feel overwhelmed by deluge of data, survey finds
By Eve Tahmincioglu updated 8:18 p.m. ET March 16, 2008

Don"t expect Shaun Osher, the CEO of Core Group Marketing in New York, to answer your e-mail right away. He has stopped responding to e-mails every minute and only checks his e-mail account twice a day. He also started turning off his BlackBerry during meetings. This tactic has made him so much more productive that earlier this year he held a meeting with his staff of 50 and "strongly suggested" that they stop relying so heavily on e-mail and actually start calling clients on the phone. And, he requested his employees put cell phones and PDAs on silent mode during meetings, as well as curtail the common practice of cc-ing everybody when sending out an e-mail. "There was so much redundancy, so much unnecessary work," he explains. "One person could handle an issue that should take two minutes, but when an email goes out and five people get cc-ed, then everybody responds to it and there"s a snowball effect." It"s not that Osher has anything against technology. In fact, he loves it. The problem is, last year he realized he was inundated with so many e-mails and so much information in general that he began to experience data overload. "In the beginning, e-mail and all this data was a great phenomenon, revolutionizing what we do. But the pendulum has swung way too much to the other side," he maintains. "We"re less productive." Osher isn"t the only one out there under a data avalanche. Thanks to technological innovations, you can be talking to a customer on your cell phone, answering a LinkedIn invitation on your laptop, and responding to email on your PDA all at the same time. Besides, during tough economic times, who will want to miss any information when your job could be on the line if you indulge in the luxury of being offline? Turns out, seven out of 10 office workers in the United States feel overwhelmed by information in the workplace, and more than two in five say they are headed for a data "breaking point," according to a recently released Workplace Productivity Survey. Mike Walsh, CEO of LexisNexis U.S. Legal Markets, says there are a host of reasons we"re all on the information brink: "exponential growth of the size of the information "haystack," the immensity and immediacy of digital communications, and the fact that professionals are not being provided with sufficient tools and training to help them keep pace with the growing information burden." Ellen Kossek, a professor from Michigan State, believes we are less productive in this age of 24-7 technology, and our multitasking mentality has spawned a "not-mentallypresent" society. "We"re becoming an attention-deficit disorder society switching back and forth like crazy," Kossek says. "We"re connected all the time. We"re working on planes, in coffee shops, working on the weekends. Work is very seductive, but yet we"re actually less effective." The key to getting your head above the data flood, according to workplace experts, is managing and reducing the information you"re bombarded with.
