1. In the altricial rodent, Phyllotis darwini, we found higher body temperatures and faster developmental rates of the thermoregulatory capacity in neonates born from coldthan warm-

the pregnancy results of 17337 inseminations carried out in a dairy herd near cairo over a period of 12 years were retrospectively analyzed in relation to environmental temperature and temperature-humidity index (thi). the overall average of pregnancy rates to all inseminations was significantly (p

the glass transition temperature (tg) and the melting temperature (tm) of gelatin at water contents between 7 and 14% were measured using differential scanning calorimetry.  the plasticisation of the polymer by water led to a decrease in tg and tm. the tg of partially crystalline gelatin was higher than that of the amorphous one obtained by quenching from the melt. the enthalpy relaxation occur...

CO2-derived methanol and dimethyl ether can play a very important role as fuels, energy carriers, bulk chemicals. Methanol production from CO2 renewable hydrogen is considered to be one of the most promising pathways alleviate global warming. In turn, could subsequently dehydrated into DME; alternatively, one-step conversion DME obtained by hydrogenation on bifunctional catalysts. this light, f...

abstract increased knowledge of russian knapweed biology would facilitate development of an optimum control program. to examine germination characteristic of this weed, several experiments were conducted in weed research department, plant pest and diseases research institute of tehran during 2003. first experiment was a factorial with 3 replications to break seed dormancy of this weed. first fa...

Sir,?Finding that a great deal of interest is now displayed in investigating the caus^ and prevention of cancer, and that bacteriologists are hard at work isolating the micro-organism, I venture to write to you the following, hoping that it may be of some service to those who are interested in the investigations. It must have been noticed by any and all of the medical profession, who had t!>e c...

This research quantifies the lag effects and vulnerabilities of temperature effects on cardiovascular disease in Changsha--a subtropical climate zone of China. A Poisson regression model within a distributed lag nonlinear models framework was used to examine the lag effects of cold- and heat-related CVD mortality. The lag effect for heat-related CVD mortality was just 0-3 days. In contrast, we ...
