Age-related dynamics of height of bone system of sapling of sheep of basic breeds of South Ural

The article presents data and analysis of the dynamics of development of individual parts of the skeleton, half-carcasses of young Tsigal, South Ural and Stavropol breeds in the conditions of the Southern Urals. Comprehensive study of the growth and development of the skeleton in the postnatal ontogenesis will develop methods of purposeful influence on the formation of myasnosti animals by sex, age and breed. The experimental data suggest that infants rams have better development of the skeleton than Mutton, due to sexual dimorphism. Thus, the superiority of the rams Tsigal rock peers on the total weight of the bones at birth was 5 g (1.5%) by weight of the bones of the axial skeleton Division - 2.3 g (1.5%), peripheral - 2.7g (1.5%) in the rock Yuzhnouralskaya this difference in magnitude to the studied parameters rams were respectively 28 g (9.5%), 12.8 g (9.5%) and 15.2 g (9.5%) at Stavropol breed - 15 g (5.3%), 6.8 g (5.3%) and 8.2 g (5.3%). A similar pattern was observed in the subsequent age periods

Regularity of self-organization of the atomic structure of the interphase boundary in a crystal-nanoparticle heterosystem

The structure of the (001) fcc/ (001) fcc interphase boundary of a system consisting of a hemispherical Ni (or Cu) crystal nanoparticle and a Pd crystal substrate was studied depending on the nanoparticle rotation angle θ = 15°, 20°, 25°, and 30°. A molecular dynamics simulation including multiparticle potentials calculated in the framework of the embedded atom method was used in this study. It was shown that, under given annealing conditions, the nanoparticle rotation depends on the size; namely, the annealing of small nanoparticles leads to their rotation to the position corresponding to the coincidence orientation at the interphase boundary, while the position of large islands remains practically unchanged. It was established that the atomic rearrangement at the interphase boundary affects only lattices with a larger parameter

Regularities of development of the main departments of muscles of young growth of sheep of the main breeds of South Ural

The article shows the development of the main departments of the muscle tissue depending on the genotype, sex, age and physiological state. It is established that, as in certain age periods, and during cultivation, the highest growth rate, as muscle mass halves, and its divisions, was the difference barancik all genotypes, and the minimum of jarocki, valoski took an intermediate position

Structural organization in the Cu₈₀Zr₂₀ metallic glass

The laws of atomic restructuring in the Cu₈₀Zr₂₀ metallic glass during melt quenching are studied by molecular dynamics simulation using statistical-geometrical analysis based on Voronoi polyhedra and cluster analysis. The morphology and size distribution of polyhedral nanoclusters in the glass structure are investigated
