This article discusses the fact that tourism is a complex socio-economic sector, which is influenced by the priority of each direction in tourism and many other factors.

This article presents the results of a study of the effect of cynoroside and thermopsoside on respiration and oxidative phosphorylation of mitochondria in vitro. It has been established that cynoroside increases mitochondrial respiration, especially during glutamate oxidation, and, on the contrary, decreases with succinate.

The article discusses the calculation of the volume of liquid in a cylindrical vessel with convex edges in the form of a cone or ellipsoid segment.

Global guidelines for control of poisons and particulate stream into the climate require intermittently checking of gases in release chimney stacks. For adequate control, the smoothes out should be straight, disposed by something like a couple of degrees from vertical. A typical issue is the event of cyclonic stream, for example stream association in at least one longitudinal vortices. The solid rotational speed part makes the smoothes out helical, nullifying ordinary speed estimations with pitot tubes or different strategies, which can be delicate to sensor misalignment with the stream. This work presents a mathematical examination of the stream inside and outside a fireplace of low length/breadth proportion with a parallel channel for ignition gases, the gases scattering in the environment, the dangerous stream design distinguished and a stream straightener proposed to diminish the vorticity inside the chimney stack, which decreases the smoothes out deviation.

The present study reports for the first time the genotypic distribution of PPARG Pro12Ala polymorphism in group of Uzbek athletes. The human peroxisome proliferator-activated receptor gamma (PPARγ) is involved in lipid storage, glucose homeostasis and adipocyte differentiation. Pro-allele contributes to the development of high physical performance in sports where you need extra physical stamina, and Ala-allele - in sports based on the strength and speed. An analysis of the distribution frequency of genotypes of the PPARG gene, based on the general model of inheritance, in the group of athletes involved in football, was statistically significant compare to control (p =0.004). These results suggest that the presence of PPARG Ala allele, which increases the sensitivity of muscle tissue to insulin, and thus enhancing its anabolic effect on skeletal muscle, predisposes the development and display of speed-power qualities. In addition, we are studied frequencies of Pro/Ala genotypes in Uzbek population in comparison with Russian, Ukrainian, Italian, Bosnian and Herzegovinian, and Ethiopian samples. In conclusion, the present data seem to suggest that some selective factors such as climate could have influenced the present distribution of the Ala allele.
