...really want to help the poor we must look at the facts. We must lock up the criminal. We must teach middle class morality and middle class work ethics and we must not expect to see a sudden change. It will be long and tedious. Liberal teaching to date has only caused problems. That is because Liberals want things as they should be according to our own high standard. Things are not as they should be and hitting the middle class in the face daily telling them to be ashamed for what they think and do will never...
...made automatic stops that would disconnect the tool at the precise depth or diameter of a cut. He made clamps to hold the metal while the guided chisels or milling wheels cut it. By dividing his factory into departments-one for barrels, one for stocks, one for each lock piece-the parts could be brought into an assembly room and put together in one continuous, uninterrupted process...
...experiments led USGS Geophysicists Raleigh and James Dietrich to propose an ingenious scheme. They suggested drilling a row of three deep holes about 500 yds. apart, along a potentially dangerous fault. By pumping water out of the outer holes, they figured they could effectively strengthen the surrounding rock and lock the fault at each of those places. Then they would inject water into the middle hole, increasing fluid pressure in the nearby rocks and weakening them to the point of failure. A minor quake-contained between the locked areas-should result, relieving the dangerous stresses in the immediate vicinity...
...discoveries of how the immune system causes allergic reactions. Researchers had determined that Immunoglobulin E (IgE), a blood fraction involved in fighting off invasions by foreign substances, is often present in abnormally large amounts in allergy victims. The Y-shaped molecules join with allergens such as pollens and then lock onto special sites on the surfaces of the connective tissue structures known as mast cells, causing them to release histamines, which in turn trigger allergy symptoms...
...years, experimenters have been analyzing the complex IgE molecule in an attempt to find the precise part of its chainlike structure that-like a key fitting into a lock-binds the whole molecule to the mast cell. Experimenting with one segment of the chain, Hamburger finally found and analyzed the structure of the binding part. He then synthesized it, producing a pentapeptide, or chain of five amino acids, that is capable of fitting the binding site on the mast cells. Injected into an allergy victim, the pentapeptide occupies the binding sites on the mast cell and blocks the complete...
