We show that SiO x , deposited at 5° to the interior surface of a liquid crystal cell allows for a surprisingly substantial reduction in the ion concentration of liquid crystal devices. We have investigated this effect and found that this type of film, due to its surface morphology, captures ions from the liquid crystal material. Ion adsorption on 5° SiO x film obeys the Langmuir isotherm. Expe...

This study presents an evaluation of an adjustable keyboard based on subjective preference and wrist joint motion during typing. Thirty-five computer users used the adjustable split design keyboard for 7-14 days during their usual work and were instructed to adjust the keyboard to the opening angle they preferred. At the end of this period, three-dimensional motion analysis was performed to com...

Systemic vascular resistance (R(sys)) of freshwater turtles increases substantially during anoxia, but the underlying mechanisms are not fully understood. We investigated whether hydrogen sulfide (H(2)S), an endogenously produced metabolite believed to be an O(2) sensor/transducer of vasomotor tone, contributes to the increased R(sys) of anoxic red-eared slider turtles (Trachemys scripta). Vasc...

Although viable fungi have been recovered from a wide variety of icy environments, their metabolic capabilities under frozen conditions are still largely unknown. We investigated basidiomycetous yeasts isolated from an Antarctic ice core and showed that after freezing at a relatively slow rate (0.8 degrees C min(-1)), the cells are excluded into veins of liquid at the triple junctions of ice cr...
