Authors: Zhang Xiwen , Hou Zhanfeng , Dai Nianzu
Published: January 2022

In view of the problems of long coating time, complicated manual operation, high multi-seed rate of coated seeds, low qualified rate, and low degree of automation of control equipment in traditional rotary coating machine, a new type of rotary coating machine was designed while using LabVIEW with a complete electric control system, which can effectively improve the speed and quality of coating. The system uses single-chip microcomputer as the lower computer, LabVIEW as the upper computer, and uses programming electronic control technology to set seed coating parameters in advance, precisely control each part and achieve precise supply. Batch supply of powder and liquid greatly improves the automation and intelligence of the operating system, improves the coating efficiency, reduces the multi-seed rate and the seedless rate, and increases the coating pass rate. In order to improve the coating quality and the supply accuracy of the coating machine, the error analysis and calibration test of the seed supply system, powder supply system and liquid supply system were carried out. After the test verification, the supply error was controlled within 2% to meet the demand for precise supply. The test results show that the pass rate of the seeds coated by the new rotary coating machine is increased by 15% to 20% compared with the seeds coated by the traditional manual coating.

Published: January 2022

Modeling the threshing and separation process involves the application of a method of description, analysis and analytical determination of system performance: threshing apparatus - working process. The modeling of the process of separating the seeds passing through an axial flow threshing device was performed taking into account that the separation function ss(x) is given depending on the length of the threshing apparatus. Then, models were made to describe the variation of the percentage (cumulative) of separated seeds ss (x=L), corresponding to the modification of the threshing apparatus functional parameters (depending on the peripheral speed of the rotor, the flow of straw parts and the moisture of straw parts).

Authors: Luo Haifeng , Chen Chaoyu
Published: January 2022

In the abandoned mine area with Karst landform in China, soils are few and thin but rocks are common, traditional planting hole diggers are unequal to work in rocks for vegetation restoration. A reamer bit with variable lateral drilling radius was designed based on the PDC (polycrystalline diamond compact) bit technology and metamorphic mechanism. Two lateral camber blades with PDC teeth were installed inside the bit body, a screw mechanism was employed as the actuation and a spatial double triangle mechanism was taken for the transmission. The curve of the camber blade was specially defined thus the reaming load was decentralized to 85.7% teeth on the blade. The kinematics of the lateral reamer bit was analysed, the mapping models from the actuation to the reaming radius and speed were established. Concrete samples were reamed indoors from 240mm to 407mm in diameter, the reaming cutting load and time length were measured and analysed. The lateral reamer bit was approved with the experiment results, this study provided equipment support for digging the planting hole in rocky abandoned mine areas and also expanded the PDC bit application.

Aiming at solving problems that the variation of tillage depth between rows and within rows caused by the surface undulation was great, the lateral stability of tillage depth obtained by the method of adjusting at the three-point suspension was poor, and lack of subsoilers with the function of accurate detection and adjustment of single row tillage depth, a method of independent control of single row tillage depth based on ultrasonic sensor detection and hydraulic adjustment was proposed. And the tillage depth monitoring and control subsoiling assembly and the subsoiler equipped with subsoiling assemblies were designed. The key structural parameters of the hydraulic cylinder and the model of the three-position four-way magnetic exchange valve were determined. The subsoiling quality and performance comparison tests were conducted, and the results showed that the mean value of the variable coefficient of soil hardness, looseness of soil and coefficient of soil disturbance were 52.23%, 32.55% and 62.15%, respectively, and the stability coefficient of tillage depth was 92.43%, which all met the subsoiling operation requirements. The standard deviation of tillage depth belonged to the method of independent adjustment of single row and unified adjustment of each row were 38.315mm and 51.521mm, respectively. The subsoiler equipped with tillage depth monitoring and control subsoiling assemblies designed in this paper was capable of significantly improving the stability of tillage depth between rows and within rows.

The corresponding findings demonstrated that the layering effect of the opener met the requirements of the fertilization standard.
STUDY ON ACTIVE ANTI ROLLOVER CONTROL AND MODEL TEST OF TRACTOR MOMENTUM FLYWHEEL
Authors: Qiao Weihong , Wei Qiuhong
Published: January 2022

The tractor working environment is complex and changeable, and the dynamic variation range of the center of gravity position of the tractor body is large. In order to avoid rollover accident, an active anti rollover control method of tractor momentum flywheel and its model test are proposed in this paper. The tractor dynamic system model and control strategy are verified by a 1:16 scale tractor model. The research results show that when the model tractor crosses the trapezoidal obstacle B, the roll angle of the whole machine is temporarily stable near 35 °, indicating that at this time, the tires on one side of the whole machine are in actual contact with the obstacle, showing a short stable state of the whole machine. When the pavement roughness reaches F-H level, without any active anti rollover control, the evaluation index EP shows a divergence trend when it is greater than 1, and the simulation calculation is terminated due to the occurrence of rollover of the whole machine. The test data and simulation results under two different driving speeds are in good agreement, which verifies the effectiveness and reliability of the tractor rollover dynamic system model and the momentum flywheel active stabilization system.

Published: January 2022

The method and parameters of experimental modelling of systems and processes in mechanical engineering are substantiated. The theory of similarity and dimensionality is used as an intermediate link between theory and experiment. The dimension of the factor space depends on the number of factors. The set of factors is grouped into dimensionless similarity criteria. The selected criteria are in certain dependence, such as the Galileo test, Euler and Reynolds numbers. Examples of application in experimental studies are given. The use of dimension theory in a factor-planned experiment allows reducing the number of factors, simplifies the mathematical interpretation of the response criterion and provides a graphical representation in the form of 3-D model.

Soil tillage, like making raised beds, is time-consuming and labour-intensive if it is done without the help of mechanization. Therefore, this study aims to develop and test a bed former powered by a hand-tractor for upland. It was carried out in the experimental field (sandy clay loam texture) at a furrower depth of 15 cm and 20 cm with a tractor forward speed of 0.5 m/s. The bed's former design results have dimensions of length, width, and height of 1200x1000x 820 mm. The performance test results showed an increase in tillage depth resulted in increased bed height, bed width, bed width, and slip. However, field capacity decreases with increasing tillage depth. The bed former's performance was found to be satisfactory in general.

THE DYNAMICS OF CHORAL CULTURE DEVELOPMENT IN CHINA IN THE 1930S ON THE EXAMPLE OF HUANG TZI’S ORATORIO ETERNAL REGRET
Authors: Yanping Xu
Published: January 2022

Choral music in China is a dynamically developing form of contemporary musical art. Scientific works devoted to the Chinese choral culture consider the 1930s of the 20th century as the most productive period in the development of this branch of musical creativity. The article examines the phase of the active entry of Chinese choral music into the sphere of the oratorio genre, which is directly related to the name of the great Chinese composer — Huang Tzi. It also highlights the issues of the country’s political life in the 1930s, which actively influenced the creation of nationwide singing movements and new choral works in the country. The oratorio genre, the genesis of which refers us to the European religious musical tradition of the 17th century, spread in China owing to the massive flow of Chinese intelligentsia to the territory of Western states throughout the entire beginning of the 20th century. In the article, the actualisation of the oratorio and its interpretation in a new light is presented as the merit of Huang Tzi, whose civic position was directly related to the desire to preserve ethnic origins in Chinese music and to complement them with Western composing techniques organically. Having proved himself not only as a composer but also as a theorist and teacher, Huang Tzi devoted most of his life to educating a large number of music professors, initiating a progressive approach to music education. His desire to raise the level of the composing school in China made it possible to enrich the repertoire of vocal and instrumental music with characteristics of the folk style. The oratorio Eternal Regret presented in the article is a unique creation that organically combines ethnic music and Western composition techniques. In the story of Emperor Xuanzong and Yang Guifei (to the poems of Tang poet Bai Juyi), taken by the composer as the theme for the libretto, there is certain symbolism that has the conceptual plan of addressing the power to demonstrate the alleged results of Kuomintang’s unclear policy. Thus, directly related to political cataclysms and their final embodiment in the form of the Sino-Japanese war (1937-1945), the oratorio Eternal Regret is presented in the article as a consolidating core that inspired the civilian masses to fight the Japanese invaders. The analysis of Bai Juyi’s original poem “Eternal Regret” and a fragmentary historical-stylistic and vocal-choral analysis of the oratorio have been carried out. The artistic features of individual parts of the oratorio, seven of which were completed by the composer, are revealed. Based on literary sources and theoretical research presented in the article, the author asserts the special role of the oratorio Eternal Regret in history and its far-reaching influence on the prospects for the development of the Chinese choir.
CHINESE SCULPTURE IN THE NEW ERA
Authors: Xiao Wei
Published: January 2022

With the advent of a new era, universal social changes pose new challenges for the art of sculpture. In terms of cultural content and practice, sculpture needs to keep pace with time. Chinese sculpture should participate in the global processes of modern sculptural development, guided by the literary and artistic concept «do not forget the past, absorb the foreign, look into the future». Not only should it receive inspiration and stimuli for development from the West but find its voice, preserving Chinese cultural tradition and Chinese national spirit.
FORMATION OF THE NEW HERO IMAGE IN RUSSIAN ART OF THE 1920’S AND 1930’S
Authors: Slepukhin Victor V.
Published: January 2022

The art of the Soviet era attracts more and more attention of researchers and the public year by year. The exhibitions held over the past decades in Russia and abroad, the published monographs dedicated to works of art of the era and particular artists, the international creative contacts in cultural field — all of that has introduced previously unknown works into art history studies, which has allowed to re-evaluate the objectives and tasks of the art of the period and the development of the artistic process in general. That is why it is of great interest to study the ways the plastic arts formed and developed in the 1920’s and 1930’s. The 1917 revolution in its foundations had not just a change in social and political reality, but also a change in the very essence of man. The new era demanded a new hero, shaped his appearance in its works. The soviet man, thought of as a new man, became a fundamentally new object of art. If the 1920’s became the time of the search in proletarian art and the flourishing of avant-gardism, then in the 1930’s the objective of art in building the lifeworld of a new man began to be understood much narrower and stricter, and this Man who perceives art began to be described as a “normal” (that is, average, “ordinary”) consumer of cultural tradition. The “New Man” in the plastic arts of the 1920’s and 1930’s was formed as the new hero of society; avant-garde artists sought his originality in the images of generalized and abstract aviators, peasants, women; artists of socialist realism began to form the images of “typical” heroes of the time (military men, athletes, rural workers, scientists) as new “Renaissance people”, equally ready for work and defense. At the same time, two main tendencies, two directions that correspond to the two tasks of socialist realism, clearly lie in the image of the “new” Soviet man: the depiction of reality (that is, the new Soviet man that really exists) and the depiction of the ideal (that is, the ideal man).

Published: January 2022

COVID-19 patients are known to have immunosuppression due to decreased lymphocytes and increased susceptibility to co-infections (Bacterial and fungal). We present a case of 61-year-old patient who had diabetes, hypertension and ischemic heart disease with COVID-19 infection admitted after RT-PCR positive result. He developed rhino-orbital Mucormycosis during treatment. He received Remdesivir with parenteral Methylprednisolone and Meropenem. While admitted in the ward, he developed signs of orbital cellulitis. Magnetic resonance imaging (MRI) of the brain, orbits, and paranasal sinuses revealed right frontal, ethmoidal, and maxillary sinusitis with the extension of the sinisuidal disease to the orbit. A nasal biopsy revealed broad aseptate filamentous fungal hyphae suggestive of Mucormycosis. Long-term use of steroids/monoclonal antibodies/broad-spectrum antibiotics may contribute to the predisposition to fungal disease. Early diagnosis and prompt management are warranted to avoid morbidity.
