1、microscopicmess349Migrant WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This
2、is particularly the case in the Middle East,where increased oil incomes have enabled many countries to call in 0utsiders to improve local facilities.Thus the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, inc
3、luding South Korea and Japan.In view of the difficult living and working conditions in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and
4、 this is a major attraction。 An allied benefit is the low taxation or complete lack of it. This increases the net amount of pay received by visiting workers and is very popular with them.Sometimes a disadvantage has a compensating advantage.For example, the difficult living conditions often lead to
5、increased friendship when workers have to depend on each other for safety and comfort.In a similar way, many migrant workers can save large sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge
6、to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which affects migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great co
7、nfidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case, migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.DreamsEveryone can dream. Indeed, everyone
8、does dream. Those who claim that they never dream at all actually dream just as frequently as the rest of us, though they may not remember anything about it. Even those of us who are perfectly aware of dreaming night after night very seldom remember those dreams in great detail but1 merely retain an
9、 untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our senses so that we appear to experience sound, touch, smell, and taste.One of the worlds oldest known written documents is the Egyptian Book of Dreams. This volume is about five thousand years old,
10、so you can see that dreams were believed to have a special significance even then, Many ancient civilizations believed that you should never wake a sleeping person as, during sleep, the soul had left the body and might not be able to return in time if the sleeper were suddenly awoken .From ancient t
11、imes to the present day, people have been making attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream as there are books.Scientists Develo
12、p Ways of Detecting Heart AttackGerman researchers have come up with a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection1 from sudden death from cardiac arrest.In Germany alone around 100,000 people die annually as a result of cardiac arr
13、est and many of these cases are caused by disruption to the hearts rhythm. Those most at risk are patients who have already suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing life-threatening disruptions to heart rhythms and correcting them automatically
14、 by intervening within seconds. These devices take on a range of functions, such as that of pacemaker.Heart specialists at Freiburgs University Clinic have now achieved a breakthrough with an implanted defibrillator capable of generating a six-channel electrocardiogram ( ECG) within the body. This i
15、ntegrated system allows early diagnosis of acute blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that rende
16、rs the evaluation of ECG data more precise.The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. “Many of the current programs only take into account a linear correlation of the data. We are, however, making use of a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system,” Hagen Knaf says, “In this
