SHOCKING ELECTROFYING PERSON

adhish — Thu, 21 Jan 2010 13:31:44 +0000

A West Australian country doctor who has won a worldwide cult following online for his spectacular displays of electrifying exhibitionism has come up with another feat of high voltage chutzpah. The project, which Dr Peter Terren calls the Modern Thinker, involves passing about 200,000 volts of electricity over his body, a routine that transforms him into a human sparkler for all of 15 seconds. Terren explained in a short note that" he wanted to convey the concept of the modern electrical age with the barrage of electrical interference in our lives". It shows the amateur physicist - striking a pose imitating Rodin's The Thinker statue - channelling an arc of electrical current that leaps down from the crackling semi-circle of sparks suspended over his head.

How To Type Special Characters Using The ‘ALT’ Key.

Ankit — Mon, 12 Oct 2009 18:07:18 +0000

Have you ever Wondered how someone makes a '±' , 'µ' or even a ™ (Trademark) with a Keyboard?

Computer systems based on Western English language use a particular character set known as US-ASCII or simply ASCII, which may or may not contain the characters we need. These character set has been replaced by the ISO 1 character set that contains more foreign individual characters. Typically, a character set includes a lot more characters than we use in the course of normal writing. We can access these "hidden" characters by using a modifier key, most commonly the 'Alt' key (for windows).

Getting things started :-

Make sure 'Num lock' is on!

All you need to do is Hold down your "ALT" key and press another key/keys on the keyboard to create a symbol. It's that easy!

Here is a list of some you can make. Have Fun!!

Alt +0162 = ¢ , Alt +0163 = £ , Alt +0165 = ¥ , Alt + 0128 = €

Alt +0169 = © , Alt +0174= ® , Alt + 0153 = ™ , Alt + 0161 = ¡

Alt +0177 = ± , Alt +0191 = ¿ , Alt +0215 = × , Alt + 0247 = ÷

Alt +0190 = ¾ , Alt +145 = æ , Alt + 155 = ¢ , Alt + 156 = £

Alt + 157 = ¥ , Alt +159 = ƒ , Alt + 171 = ½ , Alt + 172 = ¼

Alt + 225 = ß , Alt + 230 = µ , Alt + 241 = ± , Alt + 0134 = †

NOTE:-

* This only works with programs which accept an ASCII input, such as email, Notepad, WordPad, MS-WORD etc. Programs that do not support this feature may render the character as a question mark (?).

* This only works with the 'ON' number pad key on Desktops. These codes may not work with laptops or notebooks which does not consists of 'Num lock' key.

112 is the international emergency number for mobile phones 112 is the worldwide Emergency number for Mobile . If you find yourself out of coverage area of your mobile network and there is an emergency, dial 112and the mobile will search any existing network to establish the emergency number for you, and interestingly ...this number 112 can be dialed even while the keypad is locked. Try it out. Mobile phones can be used in countries with different emergency numbers. A traveller visiting a foreign country does not have to know the local emergency numbers, however. The mobile phone and the SIM card have a preprogrammed list of emergency numbers. When the user tries to set up a call using an emergency number known by a GSM(Global System for Mobile communications) phone, the special emergency call setup takes place. The actual number is not even transmitted into network, but the network redirects the emergency call to the local emergency desk. Most GSM mobile phones can dial emergency calls even when the phone keyboard is locked, the phone is without a SIM card, or an emergency number is entered instead of the PIN. GSM mobile phones have 112 as pre-programmed emergency number which is always available.^[The SIM card issued by the operator can contain additional country-specific emergency numbers that can be used even when roaming abroad. The GSM network can also update the list of well-known emergency numbers when the phone registers to it. Using an emergency number recognized by a GSM phone like 112 instead of another emergency number may be advantageous, since GSM phones and networks give special priority to emergency calls. A phone dialing an emergency service number not recognized by it may refuse to roam onto another network, leading to trouble if there is no access to the home network. Dialing a known emergency number like 112 forces the phone to make the call possible on any network. How to disable a STOLEN mobile phone The Rumor says that inputting "*#06# into your phone will reveal your serial number. It says that you should write that number down and if your cell phone is lost or stolen, giving the number to your cell provider will give them what they need to disable your phone. This doesn't work on every phone, but some phones do reveal what is called an International Mobile Equipment identity or "IEMI" number when punching in the code of "*#06#." This is especially true for GSM/DCS/PCS phones. If such a phone is stolen, it can be "greylisted" or "blacklisted." Greylisted means that the phone can still be ...

22 July eclipse is best chance to look for gravity anomaly

adhish — Tue, 21 Jul 2009 04:20:37 +0000

On 20nd July,09 A crew of Chinese scientists is planning to conduct an experiment on July 22, for the first time to test how much the controversial theory that gravity drops slightly during a total eclipse is true. It will take many more months before the final decisionto be made , but scientists are already studying the latest data. The last solar eclipse of the millennium served as a great opportunity to test a phenomenon found by Maurice Allais in 1954. Allais believed that a solar eclipse can affect Earth's gravity. The scientists in charge of the experiment have received most of the data. Pendulums were set up in many countries, with some in the path of the eclipse and others not. Some of the early results are interesting. Pendulums typically swing back and forth as a result of gravity and the rotation of the Earth. Video cameras taped the pendulum movements before, during and after the solar eclipse. Although no change was viewed in the pendulums outside of the eclipse path, two different sites in Europe revealed exciting results. These researchers, which were inside the path of the eclipse, discovered a change in the pendulum's path. If the results are correct, then another mystery was just created. Why would gravity change only in the areas under the eclipse' path? The results were taken by only looking at the video. The tapes will be studied frame by frame, which will allow scientists to analyze them very closely. Koczor says much of the data still needs to be analyzed, but the current results have stumped the scientific community. "It's easy if we see nothing," Koczor says. But if there's something there, "it's a different ball game." Now scientists got another chance to observe this phenomenon closely, enough to explain why gravity would change during solar eclipse? According to a report in New Scientist, geophysicists from the Chinese Academy of Sciences are preparing an unprecedented array of highly sensitive instruments at six sites across the country to take gravity readings during the total eclipse due to pass over southern China on July 22. The results, which will be analyzed in the coming months, could confirm once and for all that anomalous fluctuations observed during past eclipses are real. "I'm not really convinced the anomaly exists, but it would be revolutionary if it turned out to be true," said Chris Duif of Delft University of Technology in The Netherlands. The team hopes that the vast distance between the sites (roughly 3000 kilometers between the most easterly and westerly stations), as well as the number and diversity of instruments used, will eliminate the chance of instrument error or local atmospheric disturbances. "If our equipment operates correctly, I believe we have a chance to say the anomaly is true beyond ...

what is yellowcake?

neha — Fri, 12 Jun 2009 17:19:36 +0000

Yellowcake (also called urania or uranium oxide U₃O₈) is a kind of uranium concentrate obtained from leaching ( the extraction of certain materials from a carrier int o a liquid ), in an intermediate step in the processing of uranium ores. Yellowcake concentrates are prepared by various extraction and refining methods, depending on the types of ores. Typically yellowcakes are obtained through the milling and chemical processing of uranium ore forming a coarse powder which is insoluble in water and contains about 80% uranium oxide, which melts at approximately 2878 °C. The name comes from the color and texture of concentrates produced by early mining operations;modern yellowcake is brown or black. Yellowcake is used in the preparation of fuel for nuclear reactors and may also be turned into enriched uranium suitable for use in weapons and reactors. It possess the density 2.055 g/cm³, solid . Nuclear power plants generate around 20 percent of the electricity produced in the United States The basic aim of nuclear scientist is to increase the amount of u-235 atoms, a process known as enrichment.In the enrichment process the yellow cake is dissolved in nitric acid and subjected to a series of chemical processes before being converted into gas -uranium hexafluoride -by heating to above 64 degrees centigrade. Uranium hexafluoride is corrosive and reactive and must be handled very carefully. Pipes and pumps at conversion plants are specially constructed from aluminium and nickel alloys. The gas is also kept away from oil and grease lubricants to avoid any inadvertent chemical reactions.
