Selecting number and location of support rollers of crawler tractor based on analysis of vibrations of upper branch of rubber track
Authors: Zhdanovich Ch. I. , Plishch V. N.
Published: July 2023

An analytical dependence was obtained to determine the amplitude of vibrations of the rubber track in the span of the free branch of the tractor bypass between the supporting rollers. The process of oscillations of this type of track in the middle of the span of a free branch during the operation of tracked tractors of the brand “Belarus” in pull and transport modes, taking into account the speed of movement, is investigated. It is shown that the resonant modes of transverse vibrations of the rubber track at the operational ranges of the tractor operation should be taken as the determining criterion for choosing the parameters of the spans of the free branch of the bypass. The maximum values of the oscillation amplitudes of such a track in the span of the free branch of the bypass between the supporting rollers for the family of tracked tractors “Belarus” under different operating modes are calculated. A frequency analysis of oscillations was carried out and it was found that on tracked agricultural tractors with rubber tracks, a mode of occurrence of resonant oscillations in the span of the free branch of the bypass between the supporting rollers is possible. An analytical dependence has been obtained to determine the limiting distance between the supporting rollers of a tractor with a rubber track and elastic and locked suspensions according to the criterion of deducing the resonant mode of vibration of the track in the span of a free branch outside the operational range of the tractor. The values of the maximum distances between the support rollers for tractors “Belarus” 1802, 2102 and 2103 at different suspension modes are calculated. The required number of supporting rollers is determined and recommendations are given on the place of their installation. The results of these studies can be used in the creation and operation of tractors with rubber tracks

Authors: Smagina M. N. , Smagin D. A.
Published: July 2023

The results of the study of the heating process of wet capillary-porous bodies of various compositions (meat products) during heat treatment in dry air and steam-air mixture under conditions of forced circulation of the heating medium are presented. The studies were carried out on a moist fat-free sample (chicken fillet meat) and a low-moisture fat sample (pork shoulder blade) formed in the form of a cylinder and a plate. It is shown that the process of heating of meat products of various compositions obeys the laws of the theory of unsteady thermal conductivity of homogeneous bodies, despite the variety of accompanying phase and physico-chemical transformations. It is established that the regular mode of non-stationary thermal conductivity occurs at Fo ≥ 0.2 for all the studied variants. Based on the processing and analysis of experimental data, criterion equations of the form Θ = f(Fo,Bi) for the central layer of the studied products in the temperature range 160–240 °C were obtained. It has been established that the peculiarities of heating of meat products in a vapor-air mixture environment lead to lower values of the coefficients μ1 and N(Bi) at regular operation compared with heating in dry air. It was found that low-moisture fatty samples are characterized by lower values of μ1 and N(Bi) in comparison with moist fat-free ones. As a result of comparison with tabular data for solids, it is shown that the experimental coefficients μ1 and N(Bi) are characterized by lower values for all the studied variants. It is established that the nature of the change in N(Bi) and μ1 for solids and the studied products is opposite, i.e., with an increase in the number of Bi, an increase in N(Bi) and μ1 is characteristic for solids, while their decrease is characteristic for the studied products. The practical significance of the research consists in improving the quality characteristics of minced meat products and optimizing operational production planning through the use of the methodology of predictive calculation of the duration of thermal operations.

Authors: Revinskaya I. I. , Kamlach P. V. , Liashchevich Yu. I.
Published: July 2023

In this paper, a developed hardware-software complex for studying volume parameters of breathing is considered. To estimate the volumetric parameters of breathing, a method for registering the movement of the chest and abdominal walls by changing the overall dimensions of the chest and abdomen with ranking according to the anatomical features of a person is proposed. A technique for researching the volumetric parameters of breathing based on the method of video recording of the movements of the chest and abdominal wall of a person was developed. The proposed method was used to estimate volume parameters of breathing among men aged 20–22 years. BMI (body mass index) ranged from 18.2 to 30.1 kg/m². The research of volumetric parameters of respiration was carried out using the hardware-software complex and the proposed technique for registering the biomechanics of breathing. Conclusions about the relation between volumetric parameters of breathing and the values of changes in the overall dimensions of the chest and abdomen during respiration were drawn. A correlation-regression analysis of the volumes of inhaled/exhaled air and the values of deviations of the overall dimensions of the chest and abdomen was carried out. The results obtained indicate a strong relation between volumetric parameters of breathing and the values of deviations in the overall dimensions of the chest and abdomen.
Device characterization of gallium nitride high electron mobility transistor with a boron nitride heat-spreading element
Authors: Volcheck V. S. , Stempitsky V. R.
Published: July 2023

A local thermal management solution for high electron mobility transistors based on GaN was developed using a BN layer as a heat-spreading element. The thermally conducting and electrically insulating nature of BN allows it to be placed close to the active area and to be in direct contact with the electrodes and the heat sink, thus introducing an additional heat-escaping route. The numerical simulations of a GaN high electron mobility transistor with the BN heat-spreading element revealed the improvement in the DC, breakdown, small-signal AC and transient characteristics. In case of sapphire substrate, the maximum temperature in the device structure operating at a power density of 3.3 W/mm was reduced by 82.4 °C, while the breakdown voltage at a gate-source voltage of 2 V was increased by 357 V. The cut-off frequency and the maximum oscillation frequency at a gate-source voltage of 6 V and a drain-source voltage of 30 V were enhanced by 1.38 and 1.49 times, respectively. We suppose that the proposed thermal management method can be adapted to other high-power devices.

Published: July 2023

To improve the efficiency of the onboard correlation-extremal tracking system in the presence of isomorphic transformations of the current object image (changes in the brightness level, scale, shift and rotation of the image), as well as natural and artificial noise during the observation process, a new method of adaptive formation of the reference image is proposed. It consists in using an Interactive Multiple Model (IMM), which includes Kalman filters of the 0th and 1st order and a Singer filter of the 0th order. The proposed method of adaptation is compared with the known methods of frame-by-frame change and “exponential smoothing”. To carry out comparative modeling of a mathematical modeling complex, in which an input action simulator based on the Unity3D cross-platform environment was used, taking into account the kinematics of the movement of ground objects and the flight of an unmanned aerial vehicle in a natural coordinate system. The effectiveness of the evaluation of the tracking of ground objects of each of the evaluations was estimated by the value of the average coefficient of tracking. The obtained research results can be used in the development of reconnaissance UAVs operating in real time.

Authors: Pauni Micaela , Mazzuzz Cecilia , Agosta Guillermo
Published: July 2023

Spinal muscular atrophy (SMA) is a rare, but severe disease, which is characterized by progressive muscular weakness resulting in permanent assisted ventilation before the age of 2. Supportive care used to be the only available treatment. However, relevant progress has been achieved with the approval of nusinersen (an antisense oligonucleotide modulating SMN2 splicing), which changed the disease outcome for many patients. Thus, management of SMA patients requires a multidisciplinary approach with pharmacological and non-pharmacological treatments to provide the necessary supportive care for symptom management, nutritional support and active rehabilitation to optimize muscle function. In this paper we aimed to report the first patient with type 1 SMA in the Latin America region that was able to get off the ventilator without a tracheostomy after an early treatment with nusinersen, continuing to date stable and with no need of ventilatory support.

Authors: KORKMAZ Burak Can , ALTINSOY Mustafa Gökhan
Published: July 2023

Many countries are currently focusing on obtaining financial income through the use of underground resources and promoting awareness of natural hazards. However, geology education, including these issues, is often limited to superficial coverage under geography courses in countries like Greece, China, Indonesia, and Slovenia. In contrast, some countries like Portugal struggles to engage students in their secondary school geology curriculum. While some consider that geology education is too complex for primary and secondary school students, there is evidence that new technologies, such as VR and gaming, can facilitate geology education. This review article aims to clarify the importance of geology education in schools, discussing its scope and the different approaches taken in various countries. A literature review was conducted in this study. It is obvious that geology education should be included in the school curriculum for all countries to raise awareness among primary and secondary students. Most importantly, geology education is essential for countries rich in underground resources and at risk for geological events such as earthquakes.

The rice varieties IR50 and TKM-9 were raised in the second season favourable for blast. Treatments were in the form of seed treatment, nursery treatment or both in seedling stage and followed by two fungicidal spray in the mainfield at tillering and late booting along with a need based application and a control for comparison. All the treatments were found to be better than the need based and untreated control in recording a lower incidence of blast and a higher yield in both the varieties. It is observed from the present experiment that for susceptible varieties, need based application is not sufficient as it is in par with untreated control in all respects. A minimum protection not only reduces blast, but also helps in increansing the yield, even in a susceptible variety

The results of the three years INP sequence study revealed the possibility of raising three crops in the sequance of groundnut - blackgram- gingelly or cumbu soybean or blackgram - gingelly under rainfed conditions, when the monsoon is early and well distributed. When monsoon is erratic raising of two crops in the sequences of groundnut + redgram or groundunt - mustard, or cumbu-soybean or cumbu-mustard were found to be ideal. Raising of second crop of rainfed groundnut after the harvest of July sown kharif groundnut was not economical. Simultaneous sowing of redgram as an intercrop in groundnut in 6:1 proportion gave better yield and net return (Rs.5163/ha) during normal as well as erratic monsoon years.
