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.
Relevance and necessity of the dissertation topic. In the textual studies of the peoples of the world, attention to the study of national literary heritage based on primary sources is growing stronger than ever. The study of manuscript sources, regardless of the era in which they lived, allows to restore the texts of the works of a poet or writer according to the original (at least close to it). Without restoring a reliable text, the poet's work cannot be analyzed in terms of theoretical problems of literary studies. In world textology, research is being conducted on scientific problems such as comparative analysis of manuscript sources, creating a scientific biography of the creator, studying the history of the text of an artistic work. Among them, a great deal of experience, knowledge and material was collected in the framework of studying the sources of Eastern manuscripts scattered throughout the world's libraries, including the works of Alisher Navoi and Babur, great figures of Turkish literature. Extensive research is the basis for the creation of the theoretical foundations of textual studies. Uzbek textology is progressing on the basis of existing scientific experiences and has achieved and is achieving certain results in the study of classic literary sources. Researching the literary heritage of creators who left a bright mark in the history of national literature based on the original, studying manuscript and lithographic sources based on the latest scientific achievements is one of the priority tasks of source studies and textual studies. Because "... it is of great importance to study and promote Uzbek classic and modern literature at the international level, to analyze this multifaceted topic in integral connection with the most important processes taking place in the world literary space today, and to draw the necessary scientific and practical conclusions" 1 . Accordingly, it becomes clear that it is urgent to carry out a scientific-monographic study of the sources of the lyric book of Khorezm's representative Mutrib Khonakharob (1853-1923), to study the textual history of the poet's works, and to develop the principles of preparing a scientific-critical text.

Эффективная декомпрессия кисты, достигаемая путем создания «окна» в костной полости, позволяет не только санировать полость кисты антисептическими растворами, но и получить необходимый гистологический материал (костный материал и оболочку кисты). Заполнение дефекта костной полости новообразованной костной тканью происходит в результате вторичного остеогенеза.
Ушбу изланишда ички ва ташқи қатламлари композит материаллар билан ўралган ўртасида металл қатламли цилиндрсимон қобиқларнинг узоққа чидамлилиги ва мустаҳкамлиги кўриб чиқилган. Металл қувурлар маьлумки, кислота, ишқор каби агрессив мухитларга чидамсиз бўлади яьни коррозияга учраш натижасида ўзининг мустаҳкамлигини ва узоққа чидамлилигини йўқотади. Металл труба (қувурларнинг) юк кўтариш қобилятлари компазит қувурларникига нисбатан бир неча баровар катта бўлади. Агар юк кўтарувчи қатлам сифатида металл қувирларни танласак ва уларни ички , ташқи қатламларини агрессив муҳитга чидамлик композит материаллар билан ўраб чиқсак, коррозияга чидамлилик ҳам агрессив муҳитларга бардош берадиган ҳамда ташқи динамик ва статик юкларни бемалол кўтарувчи мустаҳкам ва узоққа чидамли резервуарлар ва қувирларни ҳосил қилишимиз мумкин. Бундай цилиндрсимон комбинацяланган уч қатламли қобиқларни мустаҳкамлигини ва устиворлигини ҳисоблашда ҳам анизотроп материалларни ҳамда изотроп материал сифатида металл (пўлат) қобиқларнинг физик-механик хоссаларини ҳисобга олишга тўғри келади.
Purpose of the study: to study the effect of the combination of valsartan and sacubitril on the indices of central hemodynamics in patients with coronary heart disease (CHD) within 2 years after revascularization. Material and research methods. The study included 320 patients with coronary artery disease who underwent coronary revascularization. All patients were divided into 2 groups: patients who received valsartan (group B, 160 people), patients who received ARNI - a combination of valsartan and sacubitrile molecules (group C, 160 people). At baseline and in dynamics after three months, at the end of the first and second years of follow-up after revascularization in patients with coronary artery disease systolic the blood pressure (SBP, mm Hg), diastolic blood pressure (DBP, mm Hg), heart rate in minute, the concentration of brain natriuretic peptide (BNP) in the blood were determined. Also, during echocardiography, the stroke volume of the heart, indexed to the body surface area (SI, ml / m2), the minute index (MI, ml / m2), the mean pressure in the pulmonary artery (PA, mm Hg) were determined. Research results. In the group of patients taking valsartan (group B), the relative dynamics of BNP concentration was -10.69 ± 0.55% by the 3rd month of observation, -21.24 ± 1.03% by the end of the 1st year, and -34, 39 ± 1.64% by the end of the 2nd year of observation. The inclusion of sacubitril in the therapy scheme contributed to a greater positive effect in reducing the BNP concentration: the relative dynamics of the BNP concentration was -10.30 ± 0.52% by the 3rd month of observation, - 21.91 ± 1.00% by the end of the first year of observation, and -39.28 ± 1.67% (p <0.05 significant difference with group B). By the end of the 1st and 2nd years of observation, the use of a combination of valsartan and sacubitril contributed to a more pronounced decrease in blood pressure (p <0.01), a more pronounced dynamics of MI (p <0.05) and a decrease in pressure in РA (significantly lower baseline indicators, p <0.05 and indicator in group B, p <0.01). Conclusion. The present study revealed a positive effect of revascularization and subsequent therapy of coronary artery disease with the inclusion of sacubitrile on the BNP concentration, blood pressure and mean pressure of pulmonary artery.
