In a statement published Friday on the prime minister's official Web site, Brown said the UK government will be working with the U.S. to "examine a range of new techniques to enhance airport security systems beyond traditional measures, such as pat-down searches and sniffer dogs."

These new measures might include using "explosive trace technology, full body scanners and advanced x-ray technology."

Writing on the first day of a new decade, Brown issued a reminder of the ongoing threat posed by international terrorism.

"The new decade," he said, "is starting as the last began -- with al Qaeda creating a climate of fear. These enemies of democracy and freedom... are concealing explosives in ways which are more difficult to detect."

The Detroit incident highlighted an "urgent" need to tighten airport security measures, Brown said.

"The UK," Brown said, "will continually explore the most sophisticated devices capable of identifying explosives, guns, knives and other such items anywhere on the body."

The alleged plane bomber, Umar Farouk AbdulMutallab is believed to have concealed explosives in his underwear.

The 23-year-old Nigerian is thought to have linked up with an al Qaeda group based in Yemen after attending the UK's University College London.

Brown said the plot was a reminder of al Qaeda's increasing influence away from "better-known homes of international terror such as Pakistan and Afghanistan." 1. When did the primie minster write?

input: Make use of the article to answer the questions. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.

The Warnerke Standard Sensitometer consisted of a frame holding an opaque screen with an array of typically 25 numbered, gradually pigmented squares brought into contact with the photographic plate during a timed test exposure under a phosphorescent tablet excited before by the light of a burning Magnesium ribbon. The speed of the emulsion was then expressed in 'degrees' Warnerke (sometimes seen as Warn. or W.) corresponding with the last number visible on the exposed plate after development and fixation. Each number represented an increase of 1/3 in speed, typical plate speeds were between 10 and 25 Warnerke at the time. 1. What is the speed of a insensitive film?

Find out here: Education School is expensive for many African children. Lots of families can't afford school uniforms or exercise books even though they don't have to pay for school. For those lucky enough to go to school , they have a lot to learn. Some take two language classes: English or French, and their first language. There is also math, science, history, social studies and geography. _ take up much of children's time after school. They have to get water and firewood for the family every day. Also there's cleaning , washing and helping Mum with the meal. Daily fun It's not all work and no play. Sports are very popular. Children can make goals with twigs ( )and their own footballs with plastic and bits of string ( ). They play in the country and the streets of old towns. There're many football teams for teenagers in Africa. Internet It's really expensive to get on the Internet. To surf the net for 20 hours costs over 600yuan. This is more than the average monthly pay per person. Egypt and South Africa are the top two users of the Internet in Africa. All of the capital cities there can get on the Internet. Some schools offer computer lessons but few students can enjoy computer fun at home. 1. What is expensive for many African children?
