The Mars Science Laboratory (MSL) made a successful landing at Gale crater early August 2012. MSL has an environmental instrument package called the Rover Environmental Monitoring Station (REMS) as a part of its scientific payload. REMS comprises instrumentation for the observation of atmospheric pressure, temperature of the air, ground temperature, wind speed and direction, relative humidity (...
To assess the ability of the nose to warm and humidify inhaled air, we developed a nasopharyngeal probe and measured the temperature and humidity of air exiting the nasal cavity. We delivered cold, dry air (19-1 degrees C, <10% relative humidity) or hot, humid air (37 degrees C, >90% relative humidity) to the nose via a nasal mask at flow rates of 5, 10, and 20 l/min. We used a water gradient a...
HIMMELFARB, PHILIP (University of Massachusetts, Amherst), HAMED M. EL-BISI, R. B. READ, JR., AND WARREN LITSKY. Effect of relative humidity on the bactericidal activity of propylene oxide vapor. Appl. Microbiol. 10:431-435. 1962.-Because of the low toxicity of its breakdown product, propylene oxide (PO) vapor will play an increasingly important role in the preservation of foods. It is therefor...
In a previous paper Hey and Maurice (1968) have reported the effect of changes of relative humidity on the heat production and heat loss in normal naked babies in a specially constructed metabolic chamber under controlled environmental conditions. In order to evaluate the clinical relevance of these observations we have studied the control of relative humidity that could be achieved in three co...
1. The denaturation rate of partially dried crystallizable egg albumin is greatly decreased by decreasing its water content. 2. The temperature of denaturation, defined as the temperature at which half of the protein becomes insoluble in distilled water after a definite time of heating, is a linear function of the relative humidity with which the protein is in equilibrium. 3. By applying the Ar...
The filamentous phage fd was studied by both contact- and tapping-mode atomic force microscopy under conditions of controlled variations in relative humidity and changes in the applied tip force. By spin-coating freshly cleaved mica with phage containing solutions having very low salt content followed by rapid humidity control, stable and reliable sample preparation was achieved. The apparent h...
The desiccation-tolerant state in seeds is associated with high levels of certain sugars and maturation proteins. The aim of this work was to evaluate the contributions of these components to desiccation tolerance in soybean (Glycine max [L.] Merrill cv Chippewa 64). When axes of immature seeds (34 d after flowering) were excised and gradually dried (6 d), desiccation tolerance was induced. By ...
