Preempting Unintended Consequences

Sommer offers some insights on preemption. The case for preemption is that there is an inherent logic and consistency in having litigation involving nationally traded securities resolved in a single forum

Junction connectors permit strategic placement of television cameras

Cable run circuit with switching junction connectors at strategic locations enables television cameras to be plugged in with minimum effort wherever needed. Crimp-type contacts for mating connections reduce installation time and require a lesser level of technician skill than do soldered and potted connections

Apparatus for heat treating plastic belts

Apparatus performs programed rotating, stretching/shrinking and heat treatment necessary to fabrication of high-performance plastic belts. Belts can be treated in lengths varying from 7 to 48 in., in widths up to 1 in., and in thicknesses up to approximately 0.003 in

Infrared horizon locator

A precise method and apparatus for locating the earth's infrared horizon from space that is independent of season and latitude is described. First and second integrations of the earth's radiance profile are made from space to earth with the second delayed with respect to the first. The second integration is multiplied by a predetermined constant R and then compared with the first integration. When the two are equal the horizon is located

A Review: Some biological effects of high LET radiations

There are qualitative and quantitative differences in the biological damage observed after exposure to high LET radiation as compared to that caused by low LET radiations. This review is concerned with these differences, which are ultimately reflected at the biochemical, cellular and even whole animal levels. In general, high LET radiations seem to produce biochemical damage which is more severe and possibly less repairable. Experimental data for those effects are presented in terms of biochemical RBE's with consideration of both early and late manifestations. An LET independent process by which significant biochemical damage may result from protons, neutrons and negative pion mesons is discussed

Method for improving the signal-to-noise ratio of the Wheatstone bridge type bolometer Patent

Creating the Need to Know

Context-based teaching provides a strategy that gives the responsibility of learning back to the student. This approach is being used at Virginia Tech in a number of settings, including an introductory Biology class with 325 students
