5 Armenian gunmen (known as "Lisbon Five") attacked the Turkish embassy in Lisbon in 27 July, 1983. The first Armenian was killed by security guards at the start of the attack. The wife and the son of Osman Ozturk, the Turkish chargé d'affaires, and a Portuguese policeman also died in the assault, 4 people were injured. Portugal's Interior Minister Eduardo Perella said the government received intelligence information "that Armenian groups might attack Wednesday and beefed up security at diplomatic missions".
The Armenian Revolutionary Army claimed responsibility for attack.
In a message dropped in the mailbox of The Associated Press office in Lisbon, the group said: "We have decided to blow up this building and remain under the collapse. This is not suicide... but rather our sacrifice to the altar of freedom". The group said the attack had been carried out because "Turkey and its allies refused to acknowledge the genocide of Armenians".
Thin film transistor liquid crystal display
A thin film transistor liquid crystal display (TFT-LCD) is a technology which is used in LCD monitor and television displays. TFT technology can be used to give one of the clearest pictures of any flat screen display and it uses much less electricity than older screens. TFT displays are very fragile because they are made as thin and light as possible but this means they need far less space. Widescreen Displays (which have an aspect ratio of 16:9) are becoming the most popular form of television and monitor displays. Standard format (which have an aspect ratio of 4:3) was the most popular for a long time.
The number of pixels in a display screen is called the resolution.
The word resolution means the solution of a problem. Better resolution on a display screen describes how detailed a picture can be displayed. Each pixel is another detail on the screen. This is normally described as two numbers, (width) x (height).

TFT dislays are also known as flatscreen, flat-panel, and liquid crystal display (LCD) but these types are not always TFTs.
TFT displays are made with a special chemical technology called chemical vapor deposition. With this special technology very thin glass can be coated with electrically metal and still be transparent. Chemical vapor deposition makes the thinnest computer and television display screens possible.
As a result of applying this solution, a capacitor with a transistor is fixed to the pixels. Therefore, it is possible to create the necessary contrast. Among the minuses: poor viewing angle, impaired color rendering, increased power consumption. This technology has not yet been discontinued just because it is in high demand among consumers due to its affordable cost.
Most display screens have hundreds of thousands of pixels. Each pixel has to be set to the right colour (most display screens are capable of 16 million colours in each pixel). To make a clear picture, the screen might need to make millions of calculations. Any group of pixels that change to the same colour can be changed with one calculation, making the calculations much smaller. For example, if the picture to display was just a white screen, the screens processor would only calculate the colour once and use the same calculation for the whole screen. Changing one pixel at a time would take many more calculations. If the same picture was shown many times on the screen, the processor would calculate the picture once and then repeat it in whatever position and in different sizes, if needed. The processor can make very complicated calculations, but in the end it does less work. This is called rendering technology. Rendering technology in the most modern displays is like making a .
A display with a resolution of 1600 x 1200 pixels has four times the number of pixels in an 800 x 600 resolution. Without rendering technology the 1600 x 1200 display would do four times as much work as an 800 x 600 display so rendering technology is very useful to make a bigger display with some of the same parts used to make a smaller display.
The response time is the length of time it takes between the processor receiving a signal from the computer or the television station and displaying something on the screen. Today's displays have a very low response time (very fast). It is hard to see response times but they can affect a clear picture. A low response time is best for clear pictures when playing games and watching movies on the screen. For office work and internet a fast response time is less important.
TFT response time is measured as the average time it takes to change the pixels from one shade of grey to another shade of grey.
Changing a pixel between colours takes more time than changing from black to white on a display screen. TFT is very fast for changing between colours which is more important for movies and games.

At one time, there were some positive advantages of CRT displays, which are no longer true:
Negative aspects of CRT displays:
TN is an abbreviation for Twisted Nematic. This is a new kind of TFT technology. They offer higher resolutions (more pixels). TN panels have a lower response time (they react faster).
Since this article was written, there have been further developments in the technology of producing LCD displays. For more info, the main Wikipedia page on may have more up-to-date and further details.
Jenkem
Jenkem is an alleged drug that was supposedly invented in poor parts of Africa.
When it is ready to be used, it is a gas. It is created from feces left in a container to ferment for a long time.
When breathed in, Jenkem makes the person see crazy things. It is like a crazy dream, the person imagines things happening that are not really happening. The person may also hear sounds that are not really there. This is called a hallucination. Jenkem is also used to make a person happy. Because it is made out of fermented waste (or old feces), it is also very stinky.
Some say it is as if you have a curtain in front of you.
Because Jenkem is human waste and is inhaled (huffing), the person can get an infection because of the dirt and germs in the waste.
Jenkem also contains methane, which is explosive and flammable.
US Open (tennis)
The US Open is one of the four Grand Slam tennis tournaments. It is played in Queens, New York City in the USA. It is run by United States Tennis Association. The tournament has been played on three different surfaces:
The tournament was first played in 1881 for men, and 1887 for women. In 2006, the U.S. Open became the first Grand Slam to use Hawk-Eye. Hawk-Eye is a machine that can give a virtual replay of the shot that has just been played - this is useful for seeing if the ball was in or out. When a player does not agree with the umpire, they can ask to use Hawk-Eye. As of 2007, the other three Grand Slams use this machine too.
The US Open is the final Grand Slam of the year and is played over two weeks, in late August and early September.
Mobile device
A mobile device is an electronic device which its user can easily carry with them. Typical examples are a mobile phone, PDA and handheld game consoles. Mobile devices do not need an external power supply to work. Usually, they have a battery to hold electricity to work without electric wires. A user can change, send and move data by connecting to a modem or cable, or more often wirelessly.
Uses for these devices include reading and writing e-mails, surfing in the internet and listening to music. Smartphones, tablets and similar complicated mobile devices can run computer programs including computer games, and have many of the functions of a desktop PC.
Mobile devices can be classified by size and capabilities:
