The flow model of the crushing and crushing equipment is important because it allows the stone material to slide down through the crushing chamber. The crushing or crushing characteristics were achieved by testing the rock based on spring compression during crushing under controlled conditions. The input data (CSS) includes parameters such as speed, stroke, camera geometry, distribution of transmission values and mechanical properties of the material. The performance of a traditional cone crusher, which shows the performance for ore of various products. The nominal design of the conical crushing and crushing equipment is made. At this stage, it is possible to calculate a set of nominal parameters characterizing the chopper chamber. The nominal stroke and layer thickness are determined at each point of the chamber cross section. The same material was used in modeling and field tests. After each compression test, the material was screened. Distribution of the sizes received at each check. A selection function with two variables adapted to experimental data. b) functional representation in 3D. Normalized crushing of the porphyry material under study. b) the crushing properties of quartz and porphyrite were compared.
The article covers some aspects of using video materials in teaching English as a foreign language. At every stage of practical training there is a significant set of tasks that ensure successful perception of foreign language by students, which increases their motivation to study a foreign language. Video material as a model for imitation, stimulates interest, expands the knowledge of students about linguistic and cultural characteristics of the target language, and also provides effective material for the subsequent discussions. The use of video in teaching a foreign language opens up wide opportunities for the teachers and students to master the foreign language culture. Video materials take precedence over audio and print resources.
Visual information allows better understanding and reinforcement of factual information and linguistic features of speech, since visual support contributes to a complete and accurate understanding of meaning by activating attention and memory,promoting development of listening and speaking skills
The given article is dedicated to homonyms in Chinese language and in dictionary of Kuraishi, which was created by Japanese professor T. Kuraishi. In general linguistics, method of the study of homonyms with dictionaries is widely used. The study material of quantitative composition and character of homonyms was dictionary “Ivanami Tu: gokuo ziten” – phonetic Chinese-Japanese dictionary, released by publishing office “Ivanami” in Tokio in 1972, with overall quantity of 37 thousand words. In the article, characteristics of the dictionary is given in details and the fact that it can be used as a study material in researches about Chinese linguistics is taken into account.
The article presents material on a new approach to the study of degrees of
comparison of qualitative adjectives, taking into account the relationship between
language and culture. The authors share their experience of conducting a practical
lesson, in which grammatical material was considered based on the use of degrees
of comparison of qualitative adjectives in S. Yesenin’s poems as a reflection of the
poet’s worldview and his linguistic picture of the world.
Ушбу ишнинг мақсади "соматик" фразеологик бирликларни, барқарор бирикмаларни таҳлил қилишдир, бу ерда таркибий қисмлардан бири инсон танасининг бир қисмини билдирувчи сўз билан ифодаланади. 529 та фразеологик бирликлар намунаси ўрганилаётган материал сифатида таҳлил қилинади. Ҳақиқий материал манбалари сифатида инглизча-русча фразеологик луғат, “The Oxford Dictionary of Idioms” луғати , шунингдек мутахассислик бўйича аутентик матнлардан фойдаланилди. Мақолаларни таҳлил қилиб, олинган маълумотларни умумлаштиргандан сўнг, биз қуйидаги хулосага келдик: инглиз тилининг фразеологик бирлигида энг кўп ишлатиладиган соматик компонентлар: «hand» (кул) - 71 мисол - 13,42% «head» (бош) - 49 - 9,26% «eye» (куз) - 49, - 9,26% «face» (юз) - 34 - 6,43% «foot» (оёк) - 28 - 5,29% «nose» (бурун) - 24 - 4,54% «finger» (бармок) - 21 - 3,97% Бундан ташқари, тананинг ҳар бир қисми учун иборалар ўрганилиб, уларнинг асосий маънолари очиб берилган. Ўрганиш натижасида биз қуйидаги хулосаларни чиқаришга муваффақ бўлдик:
1. "Hand" "меҳнасеварлик, маҳорат" деган маънони англатади. Бундай иборага мисол: «A dab hand» - мохир қўллар, уста.
2. "Neck" сўзи билан фразеологик бирликлар "таваккал қилиш, ўзингизни хавф остига қўйиш" деган маънони англатади. Масалан: To risk one’s neck - таваккал қилиш.
3. "Eyes" ушбу органнинг асосий вазифаси "қараш, эътибор бериш, кузатиш" учун қўлланилади . Мисоллар: To keep on eye on - бировни кузатиб туриш.
4. “Ears” аъзосининг асосий функцияси бу эшитиш, демак унинг маъноси: Be all ears - катта эътибор билан тингланг.
5. “Tongue” органининг ҳам функцияси билан боғлиқ бўлган асосий маънолари мавжуд. Бундай ибораларга мисоллар: To give a tongue - гапириш, сўзлаш.
В настоящее время уделяется большое внимание фундаментальным исследованиям базальтовых стекол и волокон, а также практическому применению базальтового волокна в качестве армирующего материала в производстве композитов. Одним их эффективных способов повышения эксплуатационных характеристик базальтовых волокон является модифицирование их состава [1–5]. При производстве непрерывных базальтовых волокон фильерным способом необходимо также решать ряд технологических проблем, которые обусловлены нестабильностью химико-минерального состава базальтов и высокой поглощающей способностью железосодержащего расплава.
Object of the research: the process of training teachers of the Russian language and literature for higher schools.
Purpose of the work: scientific grounding and elaborating the effective methodology for developing philology students’ professional Russian speech based on learning fictions.

Aim of the study.To assess the degree of endothelial dysfunction and renal function in experimental ischemic stroke (EIS) in rats on the dynamics of pharmacotherapy.Materials and Methods.The subject of experimental studies were 105 adult mongrel white male rats. The object of the study were the serum and urine of rats. The model of cerebral circulation reproduced by temporary clipping of the left common carotid artery. The controls were 20 intact animals. Results. The results indicate to the development of endothelial dysfunction with EIS with the activation of neoangiogenesis in experimental animals. Pharmacotherapy with suksinasol for 7 days caused reduction of the level of ET-1 with respect to the values of untreated animal group and was still significantly higher than control group of rats in 2.5 times. At the same time, the level of VEGf A (vascular endothelial growth factor A) significantly decreased respectively to untreated group of rats in 1.65 times (p<0.01), but was still higher than control values in 1.74 times (p<0.01). development of proteinuria, microalbuminuria and creatininuria in rats with EIS apparently was due to the development of hemodynamic changes in the kidney and glomerular basal membrane permeability, and due to the enhanced excretion of toxins and protein degradation products.Conclusion. The endothelial and renal dysfunctions with activation of neoangiogenesis develop on the model of EIS. Pharmacotherapy corrects the identified changes to some extent. Tivortin and choline alfosceratewere more effective, possibly, because of decrease of hemodynamic disturbances and neurotrophic effects.
