...distorted by improvements in diagnosis. Nevertheless, Burkitt and his colleagues believe that the increases in these diseases are real, and were caused by a change in the type of food eaten in developed countries, particularly in food that reaches the large bowel with the least change: indigestible fiber, the roughest of roughage. Until about 1890, they say, the pound of bread that average Britons and Americans ate every day contained much indigestible fiber; because of more elaborate milling techniques, bread now contains less fiber and people are eating less of it. This, the researchers say, has affected both the frequency...
...true to form that this man who removed honor, dignity and outright cash from his office as President would deny his countrymen the peace of knowing that their great constitutional processes had worked justly. How tragic that a President of the United States had not the moral fiber to provide us with a moment of truth...
...know. At the Kennedy Center last Tuesday night, watching All the King's Men, based on the story of Huey Long, corruption of public officials and impeachment proceedings, he wondered to himself if this was what politics always came to-the loss of ethics and moral fiber...
Even after these ambient fiber levels have been determined, control is prohibitively expensive. Workers must be supplied with respirators, and working areas must be enclosed to prevent the spread of contamination. Powerful ventilation must be constructed. Similar precautions must be taken wherever asbestos products are sanded, drilled, ground, pressed or even handled extensively...
...process by which airborne fiber levels are measured is, unfortunately, enormously time-consuming. It requires the use of a complex air pumping device which, attached to a worker's belt, draws air through a hose connected to a filter pinned to his lapel. But even if measurement is taken over a two or three-hour period, it may not reflect the full extent of contamination, since the most dense exposure may occur only once a day or less when the substance is poured from shipping sacks into mixing bins, for example, generating huge plumes of dust...
