Avco's apparatus, called a magneto-hydrodynamic (MHD) electric generator, works on the principle that any conductor of electricity that is moved through a magnetic field will generate in itself a current of electricity. This applies not only to copper wires (as in conventional generators), but to gases, which become conductors when they are made so hot that some of their atoms separate (ionize) into electrically charged particles. If forced through a magnetic field, a stream of ionized gas causes an electrical current to flow across it. This principle has been known for years, and many efforts have been...
...potassium chloride fed into it increases its ionization and makes it a better electrical conductor. Then the stream shoots into a hollow cone made of a heat-resisting, nonconducting material (see diagram). Electrical coils outside the cone create a strong magnetic field. As the gas speeds through, a powerful current of electricity flows across it and is collected by two electrodes inside the cone...
Tuition for the Medical and Dental Schools will rise from the current $1,250 to $1,500. Rates in the GSAS, Education and Public Administration will increase from...
...suggestion by Admiral Hyman G. Rickover that the United States instigate highly-selective, European-style schools, to which only the brightest students would be admitted. Admitting that some of these schools already in existence are very successful, he nevertheless felt that it would be cheaper to repair our current system than...
...Lamont, as operated under its current policies, is not sufficient to meet undergraduate needs. During Reading and Examination periods especially, seats are difficult to locate and books even more difficult to obtain, mostly due to the inadequate reserve book system...
