We study heat transport in a class of stochastic energy exchange systems that characterize the interactions of networks of locally trapped hard spheres under the assumption that neighbouring particles undergo rare binary collisions. Our results provide an extension to three-dimensional dynamics of previous ones applying to the dynamics of confined two-dimensional hard disks [Gaspard P & Gilbert...

In the present work an experimental-numerical approach is used to study the thermo-mechanical behaviour of NiTi wire for defining what parameters are the most important in actuator designing. Tests were carried out heating, by an electrical current, a wire having a diameter of 150 m, under constant stresses of 200 MPa. Data concerning strain, applied current and voltage are acquired during the ...

A heat exchange mechanism in the head of kissing bugs helps to prevent stress and regulate their temperature while they feed on warm blood.

It is known that the share of influence microclimate on productivity animals about 20-25%. In process life, emit a large amount heat, moisture, harmful gases, including carbon dioxide, ammonia and hydrogen sulfide. If ventilation system does not work satisfactorily, concentration water vapor gases may exceed standards, as result which drastically reduce die. Currently, when creating livestock e...
