This work describes a method and apparatus designed to combat AFS, whose operating principle is based on the temperature regulation in the well. Also, the paper presents a demonstration of physical and mathematical formulas ...

For drilling, can be used mud motor (turbodrill), which consist of stator and rotor. The problem of import substitution is actual, because these details are don’t produce in Belarus. In GSTU named P.O. Sukhoi there are ...

The paper studied the process of cladding alloy based on Sn-Pb surface layer of high-alloy tool steels. It is shown that the use of plating can improve resistance steels HSS6-5-2 and X155CrMoV12-1 to the effects of pulsating ...

An expressions for a contributions of the quark flavours, the valence quarks in the nucleon spin with help the first moments of the electroweak structure functions of the DIS the leptons off the polarized neutrons and ...

Мы изучаем вклады высших порядков в аномальные магнитные моменты лептонов от диаграмм поляризации вакуума одинаковыми лептонными петлями в случае, когда отношение массы лептона в петлях к массе внешнего лептона меньше ...

In the framework of relativistic quark model based on the point form of Poincaré- invariant quantum mechanics the magnetic moment of the ρ-meson is calculated taking into account the internal structure of quarks. It ’s ...

We analyze the target mass correction to the structure functions of the deep-inelastic scattering by using Solovtsov's approach. According this approach the structure functions contain a dependence on a target mass and are ...
