Magnetic-abrasive finishing with new diffusion-alloyed materials based on dispersed metal waste

The article discusses the issues of assessing the effectiveness of the use of new diffusion-alloyed ferromagnetic abrasive materials in the technology of magnetic abrasive finishing. The productivity of processing and the roughness of the processed surface were evaluated as they are considered to be the main performance criteria of ferric-abrasive powders (FAP). There were researched three types of powders: common Fe-TiC powder, obtained by the sintering (as a reference), and two new diffusion alloyed (borated and nitrocarburized) FAP, made of low-carbon finely dispersed ferrum-based wastes. Both new proposed diffusion-alloyed powders have better cutting characteristics then reference powder, explained by the structure features and their properties. Evaluation of productivity and roughness of surface shows, that there is their direct dependence of morphology, hardness and fragility of powder particles. The best cutting characteristics has borated powders, as they have microhardness 18,000-20,000 MPa and the tendency to brittle fracture, that leads to the new less-sized particles with sharp cutting edges creation.

Evaluating significance of relation between a material electroerosion resistance and electroerosive machining pulse energy

The paper presents results of research into dependence of electroerosion resistance on the energy of discharge impulses during electroerosive machining. A new criterion is proposed for evaluation of electroerosion resistance of materials. A direct dependence has been determined experimentally between the electroerosion resistance and the energy of discharge impulses. This relation is weak and close to linear. A mathematical model has been developed for this dependence. Scope of application is defined for the research results.

INTEGRAL HEMATOLOGICAL INDICES OF NON-SPECIFIC RESISTANCE OF PIGS AS A CRITERION OF THEIR PRODUCTIVE QUALITIES UNDER THE INFLUENCE OF TECHNOLOGICAL STRESS FACTORS

The research was carried out on a purebred livestock of the main sows of the Poltava meat breed. In the blood, the amount of leukocyte formula was determined and, on the basis of the primary data, integral leukocyte indices were calculated, characterizing the nonspecific resistance of the organism. Approximate reference values of blood indices were established in the population of healthy sows of the Poltava meat breed, in which technological stress led to the development of the stage of resistance. The main load under the action of technological stress in pigs is experienced by the agranulocytic link in the blood, especially monocytes. No reliable interrelationships between blood indices and productivity indicators were established, however, a direct dependence of some indices on other links of the body's resistance was revealed.

The Institution of Khan's Power of Kazakh Tribes in the Assessments of Russian Scientists and Officials (18th — Early 19th Centuries)

On the basis of published scientific works and office-work documents, the issues of coverage of the khan power in Kazakh society by Russian scientists and officials of the 18th — early 19th centuries are considered. The relevance of the work is due to the poor study of assessments of this institution by contemporaries in the process of its gradual transformation by the imperial authorities. The need to collect information about the political institutions of Kazakh society was due to the need to integrate the Kazakh zhuzs into the general imperial space. As a result of the study, it was revealed that the assessment by Russian by the Russian authorities and the scientific community of the khan's power included three main components. The first is the election of the khans, which was viewed by observers as an integral element of the institution of the khan's power and legitimized the khan's power in society. The second is the direct dependence of the amount of power of the khan on his personal authority among his subjects, without which the ruler did not enjoy support in society. The third is the perception of the khan's power as a weak and limited to the clan nobility. In the 18th and early 19th centuries the assessments of the institution under consideration by Russian researchers did not always correspond to reality; the collected information was utilitarian and discrete.

The study involves identifying approaches to estimating the real value of digital assets received by an enterprise, controlled by it, and accounted for at a particular cost. The main purpose of the study is to identify the parameters of estimating the value of the received asset from the type of operations (mining, barter). The study uses the method of description, which allowed to establish certain features of the accounting reflection of cryptocurrency in accounting depending on the type of transaction, recognition, and valuation of such an asset. The study analysed the main operations involving cryptocurrency. It is established that upon transactions with virtual currencies, cryptocurrency, digital assets, special attention should be paid to measuring the consumer value of certain goods (assets). Different approaches to the application of measuring the consumer value of assets are analysed. The possibilities of applying the main types of value are considered, it is established that none of them exhaustively covers the essence of measuring the consumer value of digital assets, virtual currency, and cryptocurrency. The introduction of a new type of value as attributive is proposed and substantiated. The main options for cryptocurrency valuation depending on transactions with such assets are disclosed and options for using a certain type of valuation are recommended. The study provides the calculation of the attributive value depending on certain types of operations. It is established that the proposed attributive value reflects a direct dependence on income and sales of the asset, the cost of such an asset, and its recognition for tax purposes. The study provides a real example of calculating and applying the attribute value of a Bitcoin Cash coin for reporting during the revaluation of an asset
