... found that aircraft could be very useful in war, it was used for large scale reconnaissance. Then people started to add bombs to aircraft and then airplanes started to become an essence of war. After World War 2, new bombers were developed with fast speed, and could travel far distances. They could also carry nuclear bombs and missiles. The use of the bomber aircraft then led to the fighter, which was equipped with guns and missiles. Helicopters were also found to be good strike aircraft. They were armed with cannons, machine guns, rockets, torpedoes, and a variety of missiles. Vertical takeoff made the helicopter an advantage. The first flight of the F-117A was in June of 1981 in Groom ...

... to offer file-sharing facilities and provide free access to copyrighted music. There are numerous arguments originating from all sides of the debate. Many of these are mutually exclusive and, therefore, cannot all be substantiated. McDougall (2000) published an article online, in which he summates the main arguments listed below: • Copying is fair use • Copying is theft • Music wants to be free • Napster users buy more CDs • Music companies make too much money • Music companies will make more money with Internet distribution • Musicians can’t make money with Internet distribution • Musicians will make more money with Internet distribution Within the context of a report, the follo ...
... after the plans of a single master architect. Roman concrete was a fluid mixture of lime and small stones poured into the hollow centers of walls faced with brick or stone and over curved wooden molds, or forms, to span spaces as vaults. The Mediterranean is an active volcanic region, and a spongy, light, tightly adhering stone called pozzolana was used to produce a concrete that was both light and extremely strong. The Romans had developed potsalana concrete about 100 B.C. but at first used it only for terrace walls and foundations. It apparently was emperor Nero who first used the material on a grand scale to rebuild a region of the city of Rome around his palace, the expansive Domus ...
... and integration. Cable modems may offer a less expensive network solution because of its shared architecture, but that differential is more than offset by infrastructure costs required to upgrade existing networks. The largest advantage of ADSL, and it is a significant one, is the number of telephone lines already installed that can support ADSL, or prospectively available with network upgrades. Today the global ratio is in the order of 400 million to 6 million, or about 60 to 1. Aggressive upgrades will not improve the ratio to better than 10 to 1 in the next five or six years. Even in the United States the ratio today is in the order of 20 to 1, and will not likely get better for CA ...
... If your child watches a certain show daily, sit down once a week and watch the show with them. Your interest in the show will also be a supporting guide for their growing minds, influencing them for the future. AT&T has categorized television programs in a way that enables you to view children rated programs all together. A kid pushes a button on the remote, and boom, all his shows are categorized. He can then set reminders for upcoming shows and movies. This modernized TV-Guide does not relieve any of any parental guidance. This efficient system can help you do a better job at filtering through every show, to be a stronger role model. The Parental Empowerment Act—better known a ...
... the bill arose because of the recent surge of pornography on the Infobahn. The CDA criminalizes indecent speech on the Internet(Wallace: 1). The CDA describes indecent speech as anything "depicting or describing sexual or excretory acts or organs in patently offensive fashion under contemporary community standards." First take the word "indecent". This word is used because of its vague definition. Not only does this word ban sexually explicit materials, it also bans sexually explicit words too. If this were applied to the real world some of the greatest novels would be taken off the shelf. For example there is the great lesbian novel The Well of Loneliness by Radcliffe Hall. In that book ...
... system can cause as much as harm as any physical hazard. For example, a cashier in a bank can transfer some money from one of his customer's account to his own account. Nonetheless, the most dangerous thief are not those who work with computer every day, but youthful amateurs who experiment at night --- the hackers. The term "hacker "may have originated at M.I.T. as students' jargon for classmates who labored nights in the computer lab. In the beginning, hackers are not so dangerous at all. They just stole computer time from the university. However, in the early 1980s, hackers became a group of criminals who steal information from other peoples' computer. For preventing the hackers and ot ...

Most of the people who read this media item may feel hostility to the Serbs and may try to help Muslims. And also support the NATO's attacked. As a result this article can be very effective article for the Muslims. Nowadays Kosovo events have a big place on the mass media. CNN shows the bombing frames all the time, and the crying little Albanian children who are trying to escape from the Kosova, maybe they left their mother and father there. In my opinion, the problem is only one person. MILO ...
... saves time between the interval of sending and receiving a message. Sending an e-mail message halfway around the world can arrive at its destination within a minute or two.
