background physical activity and alteration of temperature as a source of stress may have adverse effects on male reproduction. objectives the aim of this study was to investigate the effect of chronic swimming and standing in cold, warm and lukewarm water on mouse spermatogenesis. materials and methods forty-nine male mice (n = 49) were randomly divided into seven groups: c, control; swc, swim...

The purpose of this study was to test the hypothesis that regulated body temperature is decreased in the preovulatory phase in eumenorrheic women. Six women were studied in both the preovulatory phase (Preov-2; days 9-12), which was 1-2 days before predicted ovulation when 17beta-estradiol (E2) was estimated to peak, and in the follicular phase (F; days 2-6). The subjects walked on a treadmill ...

This study focuses on the effects of different temperatures and temperature cycling on breakdown voltages of tantalum capacitors. High and low temperature tests and temperature cycling tests were done. In all tests the used temperatures were inside component’s operating temperature limits. After the tests, capacitors were tested for their breakdown voltage. According to results of this research...

In order to obtain control data on the temperature sense (warm and cool threshold values) of fingertips, the relationships between room temperature and either skin temperature, warm threshold or cool threshold of the middle fingertips were investigated in healthy subjects (6 males), using our thermo-esthesiometer. The skin temperature changes in a sigmoidal response with the variation of room t...

STUDY OBJECTIVE This study investigated the relation between heat and mortality in London to determine the temperature threshold at which death rates increase and to quantify the effect of extreme temperatures on mortality. DESIGN Daily data on all cause mortality and temperature were obtained for a 21 year period and the relation between them investigated both graphically and by using non-pa...

The aim of this study is to investigate how elevation of body temperature changes organs blood flow during sevoflurane anesthesia. We conducted in vivo research on 14 male Wistar rats to monitor pulse rate and arterial blood pressure and measure hepatic, small intestinal, renal, and descending aortic blood flow using a laser Doppler blood flowmeter. We assessed the changes in organ blood flow, ...

Across taxa, the early rearing environment contributes to adult morphological and physiological variation. For example, in birds, environmental temperature plays a key role in shaping bill size and clinal trends across latitudinal/thermal gradients. Such patterns support the role of the bill as a thermal window and in thermal balance. It remains unknown whether bill size and thermal function ar...

calving records from april 1996 to december 2005 comprising 31863 calving events of 1173 dairy cows in a large commercial dairy herd were used to evaluate the effects of heat stress, using temperature-humidity index (thi) on milk yield and composition and reproductive performance of holstein dairy cows under humid climatic conditions of rasht in iran. thi values were grouped into six groups: 30...

undoubtly it can be said that climate and how weather conditions effect on building shape including limited architecture elements which has been noticed at the beginning of making shelter by human beings and the principle of this need has not been changed by passing time and changing the styles and movements and definitions of art and beauty and changing needs and attitudes and expanding archit...

We acclimated adult males of three Eremias lizards from different latitudes to 28 °C, 33 °Cor 38 °Cto examine whether temperature acclimation affects their thermal preference and tolerance and whether thermal preference and tolerance of these lizards correspond with their latitudinal distributions. Overall , selected body temperature ( Tsel) and viable temperature range (VTR) were both highest ...
