European Stars and Stripes (Newspaper) - September 9, 1990, Darmstadt, Hesse Eastern . Obscured by a Blob of Haze file visibility in Small towns like Brilliant Ohio is becoming As Blurry As it is in Large cities. Despite improvement in the last 15 years Haze caused by air pollution casts a concealing cloak Over the entire Eastern United states routinely reducing visibility by More than 80 percent in Countryside and City alike a federally sponsored study has found. The Haze a is everywhere East of the Mississippi River said John Trijonis of the Santa be research corp. In Minneapolis the chief author of the study report. A you Fly All the Way Down to Florida you Fly up to Canada you Fly to St. Louis and its there a typically cutting Rural visibility to 15 Miles from the 90 Miles or so that would be possible under natural conditions a and which is still possible in some parts of the West reduced visibility is one of the easiest effects of pollution to detect but it is not the Only one. It is a sign that other More serious problems exist. But there Are encouraging findings. After a steady increase from 1950 to the Early 1970s, the study found Haze has been reduced in the Northeast and Midwest by about 10 percent in the summer and about 30 percent in the Winter. And after an even bigger increase in haziness Over the Southeast from 1950 to the Early 1970s, the Haze has essentially stabilized in that part of the country. In the 1950s and 1960s, when average annual haziness increased by about 60 percent in the Southeast and summer haziness by about 80 percent that Region caught up with the Northeast and Midwest where Haze had been a major problem for most of the Industrial age. Trijonis attributed the More recent Haze reduction in the Northeast to a decrease in the burning of Coal and the stabilization in the Southeast to a leveling off of emissions from Coal burning. He said further Haze reductions could be expected in future years in both regions As new provisions of the clean air act take effect. Differing versions of the new legislation approved by the Senate and House of representatives would both substantially reduce emissions of Fulfur dioxide from Coal burning Power plants. Fulfur dioxide Gas when converted to sulfite particles in the atmosphere has Long been the primary cause of Eastern ha2e. For now said Trijonis the Eastern United states remains covered by a a Large scale Haze Blob on the order of 1,000 Miles by 2,000 the Blanket is so pervasive he said that the Haze Over big Eastern cities can scarcely be distinguished from the broader Rural Haze that has become a More or less permanent regional condition. The findings were based on a computerized analysis of nearly four decades of visibility records collected at 137 observation stations. They Are contained in the final version of a report that is being prepared As part of the National acid precipitation assessment program a vast Federal research Effort to gauge the nature and extent of the acid rain problem. Airborne sul fates not Only cause Haze but also Are the main constituent of acid rain.

Overview Poland the second largest country in Europe is a vast Plain except for the Carpathian mountains which form part of its Southern Border and two valleys around the Oder and Vistula Rivers. The polish Economy was Hurt by both world wars and its communist government but growth in agriculture helped keep the country afloat. Poles Are overwhelmingly Catholic despite the years of communism. The capital Warsaw contains remains of elegant Manors built by the polish aristocracy. Its a fact in the 16th Century Poland ruled much of Eastern Europe but collapsed under pressure from neighbors Prussia Russia the Habsburg Empire and the pc lets visitors inside the smaller computers become the faster they work the More they do a and the less we know about them. The computer museum of Boston has taken a giant step toward removing a lot of the mystery about computers and expanding visitors understanding of How the High tech machines work. Its walk through computer which went on permanent display this summer is Tabletop personal computer with a gland problem. This $ 1.2 not in lion working Model is 50 times larger than the average pc. The keyboard is 25 feet Long. Each key is Large enough to sit on sturdy enough to stand on. It has a 6-foot floppy disk and a 40-Inch mouse to control its cursor on the 14-foot-High Monitor. You can wander around inside weaving Between the Power Supply processing and memory chips the size of a Volkswagen. By making this computer super huge the designers have found a Way to convey Basic technology in a Way that does no to scare people who Are unfamiliar with it. A Large scale exhibits break Down barriers a says museum executive director Oliver Strimpel a British born computer Wiz who came up with the display concept three years ago. A Many people have a mental Block about what a computer is. You remove that Block by making the explanation As you step inside the a a computer and weave among its components View ports let you peer inside the microprocessor the random Access memory chips and its giant spinning hard disk. Pulsing lights simulate the data flow through the computer the heart of the exhibit is the computers control Center a replica of the Intel 486 Micro processing Chip that carries out All of the instructions written by the Programmer and stored in its memory. Visitors looking through a window on the Chip see an enlarged picture of the lines etched in Silicon. As visitors emerge from the computer a software theater humorously introduces them to the world of programming. The next Stop is a Bank of six computer learning stations with pcs that give visitors a Chance to dig deeper and even write a program. United press International Page 10 c sunday september 9,1990
