conclusions the results showed that the heat stress increased by increasing air velocity and humidity in both groups. the air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity i...

In this paper, slow light in a composite consisting of core-shell nanoparticles doped in a dielectric is studied. The light-velocity slowing factor as a function of the incident light frequency is discussed and analyzed. The influence of the thickness of shell, the composition of core and shell and the geometrical shape of nanoparticles on the slowing factor is investigated. The effect of the p...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
