Get PDFThe article describes the flora and fauna of weeds in the field of winter root vegetables in the gray soils of Samarkand region. In winter, when the stock of weeds is 1-3 pieces per 1m2, the attack of autumn moth, cotton weevil, thrips and leaf-eating pests increases. Against them, Nabu (1.5 kg/ha), Nitran (3.3-6.0 l/ha) and Promethrin (2.0-3.0 l/ha) drugs are recommended; translator

Get PDFThe article presents studies on the distribution, morphology and biology of the nematode Toxocara canis, parasitizing wild and domestic dogs, in the Fergana Valley. According to the results of the studies, the morphological structure and morphometric dimensions of the species T. canis correspond to the indicators given in the literature. This information can also be used to develop recommendations for the prevention and control of this disease.
 
Modeling of oscillatory processes of viscoelastic plates in a gas flow: Modeling of oscillatory processes of viscoelastic plates in a gas flow
No full textLet us consider the problem of vibrations of a flexible hereditarily deformable rectangular plate moving ina gas at a high supersonic speed. A plate with sides a and b is flown past on one side by a gas flow. Weassume that the flow direction is parallel to side a. We assume that the plate is compressed in the samedirection by constant forces 0. We take that the deflections are small compared to the thickness of theplate, and we solve the problem in a linear statement. Taking a linear expression for the aerodynamicpressure and not taking damping into account, we obtain the equation of motion for a plate with thefollowing finite ratio
