AMPLIFICATION OF NUCLEAR MAGNETOSTATIC OSCILLATIONS IN FERROMAGNETS

Posted in 2019, Issue № 11(89) November 2019, PHYSICS AND MATHEMATICS | 0 comments

The paper is devoted to the problem of coupled electron-nuclear oscillations in ferromagnets of spheroidal shape with the frequencies in the vicinity of ferromagnetic and nuclear magnetic resonance. In this case, the spin-wave dynamic is described in the framework of the phenomenological model, the considered oscillations are the magnetostatic waves and satisfy the magnetostatic boundary conditions. The spectrum of oscillations represent a discrete set of eigenmodes, and the frequencies of some of them are obtained analytically. The amplification factor of magnetic field acting to the nuclear subsystem is calculated. The dependencies of amplification factor on the shape of a ferromagnetic sample and on the eigenfrequencies are investigated.

ASYMPTOTICS OF THE EIGENVALUES OF A FOURTH-ORDER FUNCTIONAL-DIFFERENTIAL OPERATOR WITH SUMMABLE POTENTIAL

Posted in 2019, Issue № 11(89) November 2019, PHYSICS AND MATHEMATICS | 0 comments

In this paper the spectral properties of a fourth-order functional-differential operator with a summable potential are studied. The boundary conditions are separated. The solution of the functional-differential equation is reduced to the solution of the Volterra integral equation. For large values of the spectral parameter, the asymptotics of the solutions of the functional-differential equation that defines the investigated operator is derived. Using the found asymptotics of solutions, the boundary conditions of the operator are studied. The equation for the eigenvalues of the operator is obtained. The asymptotics of the eigenvalues of the functional-differential operator under investigation is found.

THE METHOD OF MEASURING THE DENSITY OF THE PILE DISTRIBUTION ACCORDING TO THE CHARGES OBTAINED UPON CONTACT WITH THE ELECTRODE

Posted in 2019, ENGINEERING, Issue № 10(88) October 2019 | 0 comments

The considered method relates to the methods of quality control of homogeneous particles, such as pile, used when applying coatings in strong electric fields. The aim of the invention is to reduce the measurement time. The goal is achieved by the fact that electrically charged particles are dispersed in a non-uniform electric field created by curvilinear electrodes that are symmetrical about the vertical axis. The electric field has a minimum value on this axis in any horizontal section. Particles are passed through a hole in the upper electrode, which coincides with the axis of symmetry of the electric field, measure the total charge transferred to the collector installed at different heights relative to the upper electrode, and calculate the distribution function of the particle charge. Experimental data obtained on a sample of nylon pile used in applying pile coatings by electro-floating method, which prove the efficiency of the proposed method, are presented.

HOW DID THE MODALITIES IMPROVE IN AVICENNA’S LOGICS?

Posted in 2019, Issue № 10(88) October 2019, PHILOSOPHY | 0 comments

Modality among Muslim logicians was first introduced by Avicenna. The modal logic and all modalities have always played an important role in Avicenna logicians’ opinions. Avicenna has specially shown a great deal of attention to Time Modalities Theories improvement have designed a precise Inference System. Usage and improvement of modal propositions by Avicenna, not only was affected by his familiarity with Aristotelian logic, but also by his scientific knowledge including his dominance over Mathematics, since his knew this science and its branches specially Algebra were well and study of his logic shows that since he knew the parallelism of Mathematics and Logic, not only used Mathematics examples in his logic discussions skillfully, but also, used the Mathematics science to improve his logics system and specially in modality dispute. In fact, Avicenna solved the issues relative to proof or propositional truth into a special structure of Islamic theology and Mathematics science which reached its pick in his modal lessons. After Avicenna also the spirit he had revived in Arab logics has always provided opportunities to spread and improve Logics science in general and modality discussions specifically.

TARASTI’S COGNITION OF MUSICAL SYMBOL AND ROSEN’S EARLY PRACTICE OF “CLASSICAL STYLE”

Posted in 2019, ARTS, Issue № 8(86) August 2019 | 0 comments

Generally speaking, when it comes to music style, people always analyze and explain the language form of compositions, and consider the melody, texture, harmony, tonality, orchestration and form one by one. The scientific and calm analysis is often presented by charts, followed by the summary text “transformation” description. Tarasti’s music symbolization cognitive attempts to break this traditional theoretical model, while Rosen’s “classical style” analysis practice reconstructs the symbolized music narrative of group style.

Posted in 2019, Issue № 5(83) May 2019, VETERINARY SCIENCE | 0 comments

The results of studies of the effect of drug Yoddar on the meat quality of small cattle are given. It was revealed that when using the rams of the experimental group of drug Yoddar, meat meets the standards in all quality indicators, besides for some indicators it is better than meat in the control group. During the experiment, live weight and cost per 1 kg of live weight of animals of all groups are taken into account. Veterinary-sanitary examination was carried out on the slaughter site. Besides, the “technological instruction for waste processing at the enterprise of the meat industry” was fully observed. The microscopic and bacteriological indicators of the meat rams do not show that they have the best indicators that can be obtained from the experimental groups, which can explain the bactericidal properties of iodine, which enter into the body tissues. The obtained results suggest that the use of biologically active feed additive Yoddar on sheep farms of the Russian Federation is advisable because of its positive effect on metabolism, weight gain and the absence of negative impact on the safety and quality of meat.
