Synopsis Gradients of air temperature, radiation, and other climatic factors change systematically but differently with altitude and latitude. We explore how these factors combine to produce altitudinal and latitudinal patterns of body temperature, thermal stress, and seasonal overlap that differ markedly from patterns based solely on air temperature. We use biophysical models to estimate body ...

We explore how these factors combine to produce altitudinal and latitudinal patterns of body temperature, thermal stress, and seasonal overlap that differ markedly from patterns based solely on air temperature.

Thermal stresses in three brands of inlay waxes were numerically analyzed under different cooling conditions using the rheological and thermal properties of waxes. On the basis of this analysis , the shrinkage of the wax pattern was calculated. The larger the stress relaxation of the wax and the higher the ambient temperature, the smaller the thermal stress induced in the wax. The shrinkage of ...

The complicated temperature field distribution during multi-pass single-layer weldbased rapid prototyping induces complex thermal stress evolutions and residual stress distributions. In this paper, a three-dimensional finite element model with temperature-dependent material properties is presented to investigate the temperature field and thermal stress distributions in multi-pass single-layer w...

While the cellular heat-shock response has been a paradigm for studying the impact of thermal stress on RNA metabolism and gene expression, the genome-wide response to thermal stress and its connection to physiological stress resistance remain largely unexplored. Here, we address this issue using an array-based exon expression analysis to interrogate the transcriptome in recently established Dr...

ÐTransformation superplasticity of an intermetallic Ti3Al-based alloy (Super a2) is demonstrated by thermal cycling about the a2/b transformation temperature range under a uniaxial tensile biasing stress. Failure strains up to 610% were recorded at a stress of 3 MPa, compared with 110% for deformation by isothermal creep at the same stress. The strain increment produced during each half-cycle i...

the variation in climatic variables like temperature, humidity and radiations were recognized as the potential hazards in the growth and production of all domestic livestock species. thermal environment is a major factor that can negatively affect both production and reproduction in dairy animals, especially in animals of high genetic merit. among the stressors, heat stress has been of major co...

in this article, thermal stability of beams made of functionally graded material (fgm) is considered. the derivations of equations are based on the one-dimensional theory of elasticity. the material properties vary continuously through the thickness direction. tanigawa's model for the variation of poisson's ratio, the modulus of shear stress, and the coefcient of thermal expansion is...
