Ecology and social behavior of the tamarisk gerbil : insights from long-term research in the wild and semi-natural environments.

The present review provides a compilation of the published data on the ecology and social behavior of tamarisk gerbils. Both field studies and direct observations under semi-natural conditions provide evidence that the tamarisk gerbil is a nocturnal herbivorous rodent that lives in highly seasonal habitats and displays seasonal fluctuations in reproduction and spatial organization. A typical feature of the tamarisk gerbils' spatial organization is higher mobility of males during the breeding season (as compared with the nonbreeding period) and formation of temporary aggregations of males competing for access to receptive females; the composition of these aggregations was variable and depended on the reproductive condition of the females.

Ecology and social behavior of the social vole : A generalized review.

The present review is a compilation of the published data on the ecology and social behavior of the social vole. Field studies provide evidence that these voles live in family groups consisting of 1 adult male, 1 or 2 breeding females, and their offspring (1 or 2 litters). The social vole is capable of year-round reproduction, but in arid regions, the voles demonstrate seasonality in breeding.

Structure, Conductivity, and Sensor Properties of Nanosized ZnO-InO Composites: Influence of Synthesis Method.

The influence of the method used for synthesizing ZnO-InO composites (nanopowder mixing, impregnation, and hydrothermal method) on the structure, conductivity, and sensor properties is investigated. With the nanopowder mixing, the size of the parent nanoparticles in the composite remains practically unchanged in the range of 50-100 nm. The impregnation composites consist of 70 nm InO nanoparticles with ZnO nanoclusters < 30 nm in size located on its surface.

Synthesis, Structural and Sensor Properties of Nanosized Mixed Oxides Based on InO Particles.

The paper considers the relationship between the structure and properties of nanostructured conductometric sensors based on binary mixtures of semiconductor oxides designed to detect reducing gases in the environment. The sensor effect in such systems is determined by the chemisorption of molecules on the surface of catalytically active particles and the transfer of chemisorbed products to electron-rich nanoparticles, where these products react with the analyzed gas. In this regard, the role is evaluated of the method of synthesizing the composites, the catalytic activity of metal oxides (CeO, SnO, ZnO), and the type of conductivity of metal oxides (CoO, ZrO) in the sensor process.

Fatigue-Induced Evolution of AISI 310S Steel Microstructure after Electron Beam Treatment.

Research was carried out to explore the effect of pulsed electron beam irradiation on the behavior of structure and phase state in AISI 310S steel exposed to high-cycle fatigue. A 2.2 times increase in the fatigue life of samples irradiated by electron beams was revealed.
