Temperature and relative humidity have opposing effects on evaporative water loss, the likely mediator of the temperature-dependence of nephrolithiasis. However, prior studies considered only dry-bulb temperatures when estimating the temperature-dependence of nephrolithiasis. We used distributed lag non-linear models and repeated 10-fold cross-validation to determine the daily temperature metri...

The comparative performance of shaded and unshaded Zebu cross steers was studied in a Queensland feedlot from January to May 1992. The provision of shade gave no significant (P > 0.05) advantage in liveweight gain (182 V. 177 kg), feed conversion ratio (9.4 v. 9.8 kg of fresh feed/kg liveweight gain), carcase weight, dressing percentage, P8 rump fat, eye muscle area, saleable meat yield, meat c...

The objective of this study was to establish the relationships between bioelectrical impedance analysis (BIA) measures (resistance and reactance) and temperature and to determine if corrections improve BIA models for brook trout Salvelinus fontinalis when used over a wide range of temperatures. Both resistance and reactance significantly decreased as temperature increased. Application of temper...

We examined thermoregulatory behaviors in a wild population of white-faced capuchins (Cebus capucinus) inhabiting a highly seasonal dry forest in Santa Rosa National Park (SRNP), Costa Rica. The dry season in SRNP lasts approximately 5 months and is characterized by high ambient temperatures regularly exceeding 37 degrees C, low relative humidity, and the near absence of precipitation. This stu...

Culturable methanotrophic bacteria (CMB) were studied in the soils of forest and savanna of tropical dry deciduous forest ecosystems employing most probable number (MPN) technique. The spatiotemporal study was conducted at the six sites differing in the soil physicochemical properties and vegetational cover. CMB population was high in the moist sites compared to the dry sites and in sub soil be...

The effect of temperature on a very high gravity ethanol fermentation using no cook process was investigated. We found that a gradient temperature control strategy could improve the fermentation efficiency significantly, With the assistance of a new raw starch hydrolyzing enzyme and a gradient temperature control strategy, the ethanol concentration could reach up to 20% (V/V) within 90 h using ...

In order to determine factors which may affect the differential seed germination of six members of the Cyperaceae which occur together in newly revegetated sedge meadow, seeds were tested for germinability at three storage conditions. Seeds were also germinated at two alternating temperature regimes, 21/25° and 25/32°C. Germination of dry stored Carex hystericina and C. vulpinoidea was greater ...

Seasonal fluctuations in mean dry weight of the copepod Calanus helgolandicus were large and contrasted markedly with the small seasonal fluctuations of cephalothorax length. Dry weight was related linearly to cephalothorax length on logarithmic axes by a series of regression equations which were significantly different for each of 8 cruises. Carbon and nitrogen were likewise linearly related t...
