Biological Þtness of a malathion-resistant (R) and a malathion-susceptible (S) strain of the solitary parasitoid Anisopteromalus calandrae (Howard) was compared when the wasps were parasitizing immature rice weevils, Sitophilus oryzae (L.), in stored wheat. Despite having a .2,500-fold naturally occurring resistance, in the absence of insecticide the R strain was equal to the S strain in abilit...

The effect of the genotype of 2 selected rabbit strains (White New Zealand and Synthetic) on the survival rate at birth of frozen embryos was studied. Morulae were obtained 64-66 h postcoitum from 32 multiparous does naturally mated with males of the same strain (16 does of Synthetic strain (SY) and 16 does of the White New Zealand strain (NZ)). Morphologically normal morulae were slowly frozen...

Molecular dynamic simulation of low temperature plastic deformation (Tdef = 50 K, Tdef/Tg ≤ 0.3) is studied for glassy polymethylene under the regime of active uniaxial compression and tension for a cell composed of 64 chains containing 100 –CH2 groups in each (as united atoms) and with periodic boundary conditions. Thirty two such cells are created, and, in each cell, polymethylene chains in t...

A crystal plasticity-based constitutive model is developed to describe the thermomechanical behavior of pseudoelastic NiTi single crystal. The includes, for first time in literature, all inelastic mechanisms influencing fatigue SMAs a finite strain framework: martensite transformation, deformation slip austenite at high-temperature, twinning large strain, transformation-induced plasticity (TRIP...

The aim of the study was to improve methods for verifying vaccine strain Francisella tularensis 15 NIIEG during long-term storage under current conditions. Materials and . paper summarizes results studying phenotypic genetic properties lyophilized cultures F. (1953, 1966, 1969, 1987, 1990, 2003, 2012 2013) stored at SCEMAP a period one 60 years.

Obtaining different batches of beer with the same characteristics each time is a continuous challenge for brewers worldwide. Besides the complexity and natural variation of ingredients ́ composition, reusing the same batch of yeast up to 7-10 times makes the brewing process even more difficult to control. The pitching brewing yeast should have a high metabolic activity in order to meet the expec...

In order to facilitate locomotion and limb movement many animals store energy elastically in their tendons. In the turkey, much of the force generated by the gastrocnemius muscle is stored as elastic energy during tendon deformation and not within the muscle. As limbs move, the tendons are strained causing the collagen fibers in the extracellular matrices to be strained. During growth, avian te...

In our previous study, three bacterial strains, Bacillus megaterium KU143, Microbacterium testaceum KU313, and Pseudomonas protegens AS15, were selected as effective biocontrol agents against Aspergillus flavus on stored rice grains. In this study, we evaluated the inhibitory effects of the volatiles produced by the strains on A. flavus growth and aflatoxin production on stored rice grains. The...
