an infinitely long hollow cylinder containing isotropic linear elastic material is considered under the effect of arbitrary boundary stress and thermal condition. the two-dimensional coupled thermoelastodynamic pdes are specified based on equations of motion and energy equation, which are uncoupled using nowacki potential functions. the laplace integral transform and bessel-fourier series are u...
the aim of this research is to calculate the elastic constants and bulk modulus of cu-20 wt% ni random nanoalloy. the molecular dynamics simulation technique was used to calculate the mechanical properties in npt ensemble. the interaction between atoms as well as cohesive energy in the nanoalloy modeled systems was calculated by morse et al. two body potential. also the temperature of the syste...

in this research the mechanical behavior of an expansive soil (with different pore fluid) was investigated under the constant and variable temperature through experimental tests. the soil samples with different pore fluid (distilled water, nacl and cacl2 with concentration of 250 gr/lit) were prepared by static compaction method. experimental testes were conducted in two modified odometer under...
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...
temperature and precipitation are among important atmospheric parameters for watershed planning. assessment of temperature and precipitation trends is very important for future watershed planning. in this paper, trends of atmospheric parameters such as seasonal and annual temperature and precipitation were examined for the synoptic stations of bandar anzali, rasht, ramsar, babolsar and gorgan. ...
This paper addresses briefly some of the major difficulties in attempting to understand and model the geological and tectonic change of the Paleozoic and Mesozoic portions of the rock record as occurring during the span of but a single year—the year of the biblical Flood. A relatively simple tectonic model is proposed that assumes a pre-Flood earth with a single supercontinent, an intact lithos...
A meta-analysis to mathematically summarize the eVect of hot and cold temperature exposure on performance was completed. The results from 515 eVect sizes calculated from 22 original studies suggest that hot and cold temperatures negatively impact performance on a wide range of cognitive-related tasks. More speci®cally, hot temperatures of 908F (32.228C) Web Bulb Globe Temperature Index or above...
