Currently, the temporal arc distribution across the ingot during the vacuum arc remelting (VAR) process is not a known or monitored parameter. It is has previously been shown that arcs can spatially constrict during VAR, and this constriction can lead to undesired defects in the material. Additionally, correct accounting for...
There are typically two responses to the complex environmental problems of our time: 1) doom and gloom and 2) optimism. There is a lot of doom and gloom in the environmental literature. This literature warns that the future portends danger for humans and their life support systems. But when one...

Objective: To explore the controversial issue of the safety and use of mercury in
amalgam dental fillings. Methods: Using a variety of scientifically oriented studies,
overall trends and conclusions were analyzed. Relevant articles include Children’s
exposure to Amalgam, fetal exposure, environmental mercury, occupational exposure,
and mercury and Multiple Sclerosis. Additional...
The behavior of a metal vapor plasma arc in a vacuum arc remelting (VAR) furnace is believed to contribute to the formation of defects in reactive metal and super-alloy ingots. Industry standard instrumentation, which includes electric current and voltage measurements, can asses the stability of an arc but cannot predict...
A cross-cultural analysis of business practices based on video recordings of interviews with business professionals in both Oregon and Taiwan, with the intent of finding evidence to support or question current beliefs about cultural differences between American and Asian cultures. Particular focus is paid to business practices such as networking,...
The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate.
The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...
