We consider computation and selection problems in reduced models for the study of the dynamical load of the stand of the bridge of a tube-reducing machine. We design and analyze the computational scheme and obtain a system of differential equations f

The formation energies of oxygen vacancies and the migration barriers of oxygen in TiO2 with a rutile structure have been calculated by the projector augmented-wave method within the electron density functional theory. We have derived analytical expr

Reducing mills in piece-reduction at the moment of capturing the pipe’s front end and on the rear end exit are exposed to increased dynamic loads. However these processes at present time are not fully researched. The relevant problem is to decrease

Powders of the B-type synthetic apatite exposed to gamma or ultraviolet irradiation were investigated using EPR spectroscopy. It was shown that ultraviolet irradiation leads to the appearance of the EPR spectrum near g = 2, which is similar to the sp

The dependence of the inhibitive effects of new 2-thioquinazolin-4-one derivatives on the corrosivity and pH of the medium was studied. The test compounds were found to effectively inhibit the acid corrosion of steel 20; when combined with (NH4)2MoO4

The paper addresses the question of canard localization in systems with relaxation oscillations in the case when the small parameter does not approach zero. In particular, we propose a new approach of localization in phase space of the trajectory bun
