In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

Climate change is rapidly altering the way current species interact with their environment to satisfy life-history demands. In areas anticipated to experience extreme warming, rising temperatures are expected to diminish population growth, due either to environmental degradation, or the inability to tolerate novel temperature regimes. Determining how at risk ectotherms, and lizards in particula...

An endothermic phase change in the presence of chemical heterogeneitles can act as an efficient filter, such that heavy material is sequestered below the phase change and light material is trapped above the phase change. Due to the fact that the endothermlc phase change damps thermal convection, it can act as a "trap door" for chemical heterogeneitles Ascending flows which are chemically dense ...

As s‌tudents spend one-third of their time at school, their health, comfort, and productivity are mos‌tly influenced by thermal condition and indoor air quality of classrooms. Regarding that manual window-opening is a common way for providing fresh air in classes and s‌tudents aren't allowed to change their uniform, position or control the windows during the lesson hours, providing thermal comf...

In this article, curvature effects on elastic thermal buckling of double-walled carbon nanotubes under axially compressed force are investigated using cylindrical shell model. Also, the small scale effect is taken into account in the formulation. The dependence of the interlayer van der Waals (vdW) pressure on the change of the curvatures of the inner and outer tubes at that point is considered...

With respect to the limitations of fossil energy resources, different types of electric vehicles (EVs) are developed as suitable alternatives. Lithium-ion (Li-ion) battery cells play an extremely important role in EVs due to their unique features. But they need a thermal management system (TMS) to maintain their surface temperature uniformity and avoid them from thermal runaways. In the current...

The system design of window air conditioner does not evolve in one day. Due to the continous efforts are taken by the refrigeration and air conditionging professionals, successful and economic models of window air conditioners are currently used. This paper states about the development of window air conditioner with phase change material and water as refrigerants. Developed air conditioner was ...

A relatively important change in UV absorption is observed upon thermal perturbation of nucleotide solutions. Comparison of these thermal perturbation spectra of nucleic acid residues with solvent perturbation spectra of the same compounds suggests that this spectral change can most probably be attributed to temperature induced hydration change of the bases. This conclusion is confirmed by the ...
