bream (abramis brama orientalis) is one of the most commercially valuable fish in the caspian sea. the aim of this study was to compare levels of genetic polymorphism between wild and farmed bream populations using seven microsatellite loci. genetic diversity was investigated by studying samples collected from two regions; chaboksar and the artificial propagation center of guilan province. alle...

We review and extend a recent suggestion that fine-scale localization of a disease-susceptibility locus for a complex disease be done on the basis of deviations from Hardy-Weinberg equilibrium among affected individuals. This deviation is driven by linkage disequilibrium between disease and marker loci in the whole population and requires a heterogeneous genetic basis for the disease. A finding...

The imbalance in the social structure Emile Durkheim's opinion is at least influenced by three factors, namely equlibrium, external and consensus. Covid-19 pandemic that befell mankind from various directions has caused a rigid shift student learning. Where initially, educators had big role learning completeness during education level. However, after this outbreak there was function. Teachers d...

We present a new type of spherically symmetric monopole and dyon solutions with the magnetic charge 4π/e in the standard Weinberg-Salam model. The monopole (and dyon) could be interpreted as a non-trivial hybrid between the abelian Dirac monopole and non-abelian ’t Hooft-Polyakov monopole (with an electric charge). We discuss the possible physical implications of the electroweak dyon. Typeset u...

An anomaly free model of strong and electro-weak interactions involving leptons and quarks in the SU(4) x Slam x U(1) gauge theory is C constructed. After spontaneous symmetry breaking, it reduces itself into the quantum chromodynamics for strong interactions and a broken SU(3) x U(1) model for electro-weak interactions. As a limiting case it gives the same results as those of the Weinberg-Sala...

The phase transition in the Weinberg-Salam-Glashow (GSW) electroweak theory extended by the majoron and dilaton field is considered. The possibility of the boson condensation in the extreme conditions in the standard electroweak theory is shown. The first order phase transition induces by the radiative corrections (the Coleman-Weinberg potential) in the presence of matter was considered. Due to...
