Plastic responses to heat and desiccation stress in insects have been studied in many laboratory experiments on Drosophila. However, in these studies the possible interaction between the corresponding stress factors in natural environments has not been taken into consideration. We investigated changes in heat and desiccation resistance of adult Drosophila simulans after short-term exposures to ...

Microstructural and mechanical properties of precipitation-hardened maraging steel could be stated on a basis of magnetic properties of such a material. A correlation between mechanical and magnetic properties of the maraging steel is treated from the view of non-destructive testing during and after heat treatment as well as during use under unfavourable conditions at elevated operating tempera...

The age hardening of an Al-Mg-Si alloy was enhanced by the effect of high-speed (105 s11) compression prior to aging. This enhancement of the age hardening is brought about by the formation of vacancy clusters during high-speed compression. High resolution transmission electron microscopy reveals that these vacancy clusters form stacking fault tetrahedra. Following peak aging, vacancy clusters ...

A mechanism of the transport of nanocrystalline doped calcium carbonatephosphates through the membrane on the model of interaction with phospholipids is considered. Nanocrystalline doped calcium carbonate – phosphates are perspective to transport of the cations in a living cell. Kinetics of the synthesis of nanocrystalline doped calcium carbonatephosphates are non-linear kinetics. Biomaterial b...

The deformation of metallic glasses involves two competing processes: a disordering process involving dilatation, free volume accumulation, and softening, and a relaxation process involving diffusional ordering and densification. For metallic glasses at room temperature and under uniaxial loading, disordering usually dominates, and the glass can fail catastrophically as the softening process ru...
