The study aims to develop a method for traction testing of mobile machines using the principles of kinemodynamics. To achieve these goals, it is necessary to: justify the method of traction testing of mobile machines using the principles of kinemodynamics; and carry out experimental validation of the proposed test method. Methods and materials. The methodological basis of the work is the principles of kinemodynamics, namely partial accelerations. The development of a test method consists of determining the possibility of measuring the established indicators and assessing the method’s suitability. To determine the power and energy characteristics of mobile machines, it is proposed to use a measuring complex consisting of a linear accelerometer and special software for processing the measured data. Results. A method for traction testing of mobile machines using the principles of kinemodynamics has been developed; experimental validation of the proposed test method was carried out. The essence of the method is the direct measurement of longitudinal accelerations that occur during the acceleration of a car and the subsequent processing of the results of these measurements, using an energy approach based on determining the change (difference) in the kinetic energy of the car over a certain period. This made it possible to determine the force on the wheels of the car, which leads to its acceleration (or maintaining uniformly accelerated motion) and the share of engine power spent on this car. An experimental validation of the developed method was carried out, which consisted of determining the coefficient of agreement of test results with variations in certain specific factors. Conclusions. The use of the principles of kinemodynamics allows us to determine the fraction of force that leads to acceleration during the acceleration of the car and the fraction of engine power expended. Based on the test results obtained by the proposed method, the following analysis can be made: determine the conditions (gear ratio in the gearbox) under which maximum acceleration is possible, determining the share of the maximum possible design force in each gear used to accelerate the machine; determine the weighted average power reserve of the machine engine, which can be used to overcome additional interference. Experimental validation of the proposed method in terms of agreement showed satisfactory results. Keywords: traction tests, method, coincidence coefficient, power, traction force, acceleration.

The article presents the results of research on the impact of qualitative and structural characteristics of artificial rain created by sprinklers and ways and means of minimizing its negative impact on the soil by using modern low-pressure sprinklers. The purpose of the research is to study the design features of different types of sprinklers, and the practice and effectiveness of their use in the conditions of irrigated agriculture in Ukraine. Methods and materials. The study of structural and technological features of the working bodies of sprinklers, the practice of their application, and the determination of the main indicators of the quality of the generated rain were carried out in the economic conditions of their operation during the tests. When assessing the quality of work, the intensity of rain, the average diameter of the drops created, the coefficient of effective watering along the sprinkler belt of the tested machines, the specific power of rain, and the comparison of these indicators when using different types of sprinklers were determined according to the standardized methods of the relevant regulatory documents: SOU 74.3-37-152, DSTU ISO 11545. Results. Modern sprinklers are equipped with highly efficient sprinklers with a large capture area and low energy impact on the soil, taking into account all components of the impact of the quality and structure of artificial rain. At low-pressure values, such sprinklers provide a low intensity of rain due to a large spray area, good uniformity, and optimal droplet sizes. The use of these working bodies provided a solution to the problem of minimizing the negative impact of irrigation on the ecology of the environment. The high efficiency of the use of modern sprinklers was confirmed by tests of machines equipped with similar working bodies, according to the results of which a decrease in the intensity of rain and its energy impact on the soil was noted due to the low-working pressure, large coverage area, a nominal spectrum of droplet size and speed of their fall. Conclusions. The use of low-pressure sprinklers makes it possible to reduce the energetic impact of rain on the soil, which ensures the preservation of its structure and reduction of erosion processes, ensures high uniformity of irrigation at low pressure in the irrigation network, reduces moisture loss from the influence of air temperature and wind, and irrigation costs due to the reduction of pressure in irrigation network.

Published: July 2024

The Western Desert of Egypt is recognized for its significant potential in oil and gas reserves, making it a prominent hydrocarbon-producing area with conventional reservoirs. Recent findings from various wells suggest that unconventional reservoirs in the Western Desert may hold considerable promise. The primary objective of this study was to explore this potential. Accordingly, a comprehensive and multidisciplinary approach has been employed to assess the Abu Roash/F (AR/F) reservoir. The methodology involved meticulously examining formation characteristics and integrating borehole images with existing core data and thin sections. This integration aimed to analyse and interpret the lithofacies of the reservoir, with a specific focus on identifying fractures and decoding potential diagenesis effects. As a result, we successfully identified wells exhibiting optimal reservoir quality, unveiling the presence of fractured dolomite or vuggy dolomite in wells containing promising oil and gas pay intervals. Notably, some wells displayed low porosity (3%), yet seismic attribute maps in their vicinity indicated a high density of fractures. This underscores the importance of combining borehole images with seismic attributes to evaluate carbonate formations effectively. The fractures, predominantly oriented NW–SE, were found to be associated with deformation zones. Our findings emphasize the critical role of this integrated approach in unlocking the full potential of hydrocarbon reservoirs in the Western Desert.

This work has been devoted to investigate experimentally, the increase in range of horizontal discharge distance and velocity of water flow for pipes of fire-hoses and water jet propulsion systems in small ships. The enhancement method of water flow depends on increase the drag reduction and best uniform flow. One of the important practice techniques is adding a small amount of some materials, cheap and locally available added into water flow in a horizontal pipe.A simple experimental system is designed and constructed to investigate the increase in drag reduction. Nanoparticles (aluminum oxide –30 nm diameters) and polyacrylamide (PAM) have been added alone and gain time together. Experimental calculations of average flow velocity, Reynolds number, and friction factor and percentage drag reduction are experimentally calculated under water heads of 75,100, 125,150,175 and 200 cm.The effects of concentration ratios of nanofluid(AL2O3) on friction factor and drag reduction are studied and calculated. The present results showed that addition of AL2O3 and PAM are caused reducing in friction factor, increase in range of horizontal discharge distance and the velocity of water flow.Also the results indicated that, drag reduction was26% increased at addition of AL2O3 and 39% at PAM while at mixing them together was 52 % as average for six heads were chosen. The results are represented graphically to explain the degrees of enhancement of increasing in drag reduction, flow velocity and the range of discharge distance for water in horizontal pipes. The originality of this work was addition materials of nanopartcles with polyacrylamide together.

Published: July 2024

The absorption column is one of the essential separation processes in industrial operation, so the need arises to control absorption column by process simulation and also to analyze system by method called frequency response using MATLAB8. This work dealt with gas-liquid (air-water) absorption packed column which is analyzed by bode plot and frequency response to determine the stability of the system with or without Proportional Controller (P), Proportional Integral Controller (PI) or Proportional Integral Derivatives Controller (PID).The frequency response gives the transient response information, by defining such frequency response quantities as gain margin and phase margin. This work presents dynamic analysis of absorption column which is single input/single output (SISO) using feedback control (P, PI and PID) with the parameters of Cohen-Coon, Ziegler Nichols and Internal Model control and compares between them.
Whirling and Vibration of Rotating Machinery Critical Speeds and Modes
Authors: Karim Mohsen Alturshan Kadim
Published: July 2024

The paper investigate the vibration of the rotating shafts and whirling were theoretically by dealing with only the shaft bending without torsion. It is shown that the shaft whirling result from vibration consider for this particular system will have critical whirling speed which increases as the inertia forces of the rotor. Whirling is associated with fast-rotating shafts. When a shaft rotates it is subjected to radial or centrifugal forces, which cause the shaft to deflect from its rest position.These centrifugal forces are unavoidable, since material inhomogeneities and assembly difficulties ensure that the center of gravity of the shaft or its attached masses cannot coincide with the axis of rotation. The centrifugal forces involved and determined that the only destabilizing or restoring force was that due to the elastic properties or stiffness of the shaft. Hence, to deduce the critical speed caused an infinite deflection of shaft due to whirling. Loading response analysis can simulate the response of the rotor using Ansys program, which can help to identify the main modal frequency. To a rotating shaft, the modal analysis can give a serial of Eigen frequency, but only some of them are just the right modal frequency value we need. The harmonic analysis can extract the eigenvector of the modal analysis result, integrate them together, and show the amplitude frequency response, deformation and stress distribution characteristics of some special place of the rotating shaft

Para algumas espécies, a cor do tegumento é utilizada como indicativo da qualidade das sementes. Em vista disso, como as sementes de feijão guandu podem apresentar variação da cor do tegumento, é possível que esta característica física influencie a viabilidade e o vigor das sementes desta espécie. Portanto, objetivou-se avaliar o potencial fisiológico das sementes de guandu cv. Fava Larga, em função da cor do tegumento. Foram utilizados dois lotes (A e B) de sementes comerciais. Foi adotado o delineamento inteiramente casualizado, com quatro repetições e os tratamentos foram representados por quatro cores do tegumento (cinza, vermelho, laranja e mista – lote original). Em cada lote as sementes foram separadas manualmente e classificadas visualmente, quanto à cor do tegumento. Posteriormente, foram realizadas as determinações do teor de água e do peso de mil sementes. Foram avaliados primeira contagem de germinação, percentual de germinação, percentagem de emergência em campo, índice de velocidade de emergência, tempo médio de emergência, a massa seca das plântulas e a condutividade elétrica. Os dados foram submetidos à análise da variância pelo teste F e as médias comparadas pelo teste de Tukey (p < 0,05). As sementes com tegumento vermelho (lote A) e com tegumento laranja (lote B) apresentam maior vigor, demonstrando a relação existente entre a cor do tegumento e o nível de vigor.

Immunoglobulin G4-related disease (IgG4-RD) is a multisystemic immune-mediated disease, encompassing several conditions previously thought to be unrelated, which can mimic malignant, infectious, and inflammatory disorders. Head and neck IgG4-RD most frequently affects the salivary glands
and orbit; however, it can involve virtually any subsite. Diagnosis is challenging and relies on the clinical presentation, serum immunoglobulin G4 levels, and histopathology. Although imaging is nonspecific, growing knowledge of IgG4-RD allows characterization of imaging patterns and description
of novel findings. This review focuses on cross-sectional imaging findings of extracranial IgG4-RD in the head and neck, presenting cases in frequent and unusual subsites, with some cases with few descriptions in the radiological literature, such as the pharynx and larynx, temporal bone, paranasal
sinuses, and perivascular areas.Learning Objective: To describe the imaging findings of IgG4-RD in the head and neck to suggest the diagnosis and identify the involvement of common and uncommon subsites.
Apex Nasi: What’s Happening near the Tip of the Nose?
Authors: Fourgas E.C. , Mongelluzzo G.J. , Fischbein N.J.
Published: July 2024

The apex nasi (colloquially, the tip of the nose) is an anatomically complex region that can be divided into 2 parts: the soft tissue/cartilaginous framework of the most anterior-inferior aspect of the nose and the anterior nasal cavity. Detailed knowledge of local anatomy is helpful
to characterize pathology and understand patterns of disease spread. Although many lesions of the apex nasi are readily assessed on physical examination, CT and MR imaging can provide important, often complementary, information about this region. CT well demonstrates osseous anatomy, while
MR imaging offers increased specificity for certain conditions, given its superior soft-tissue contrast. Regarding specific pathologies of the region, because cutaneous cancers are common and often involve the apex nasi, they will be discussed in detail, along with potential imaging pitfalls
such as perineural tumor spread or coexistence with rhinophyma. Certain rare non-neoplastic or developmental lesions, notably nasolabial cysts and pyriform aperture stenosis, are unique to this region. Vascular lesions such as angiosarcoma and venous malformation may involve the apex nasi,
as may nasal septal hematoma and abscess, the latter necessitating immediate treatment. Given the high prevalence of rhinoplasty, the imaging appearance of cosmetic nasal implants and selected rare procedural complications is shown.Learning Objective: To describe the anatomic landmarks
of the external nose and anterior nasal cavity and to illustrate common and uncommon pathologies in these locations.

Published: July 2024

Autophagy is a central process for the degradation of intracellular components that work with disorders. The molecular mechanisms underlying this process are extremely difficult to study, since they involve a large number of participants. The main task of autophagy is the redistribution of cellular resources in response to environmental changes, such as starvation. Recent studies show that the regulation of autophagy may be the key to achieving healthy longevity, as well as to create therapeutic agents for the treatment of neurodegenerative diseases such as Parkinson’s and Alzheimer’s. Thus, the developmentof autophagy activators with a detailed mechanism of action is a really important direction for research.Several commercial companies are at various stages of development of such molecules, and some of them have already begun to use autophagy activators in practice.
N-terminal fragment of cardiac myosin binding protein C modulates cooperative mechanisms of the thin filament activation in the atria and ventricles

Cardiac myosin binding protein C (cMyBP-C) is one of the essential control components of the myosin cross-bridge cycle. The C-terminal part of cMyBP-C lies on the surface of the thick filament, and its N-terminal part interacts with actin, myosin, and tropomyosin, affecting both the kinetics of the ATP hydrolysis cycle and the lifetime of the cross bridge, as well as the calcium regulation of actin-myosin interaction, thereby modulating the contractile function of the myocardium. The role of cMyBP-C in atrial contraction is poorly studied. We examined the effect of the N-terminal C0-m-C2 (C0-C2) fragment of cMyBP-C on actin-myosin interaction using ventricular and atrial myosin in anin vitromotility assay. The C0-C2 fragment of cMyBP-C significantly reduced the maximum sliding velocity of thin filaments on both myosin isoforms and increased the calcium sensitivity of actin-myosin interaction. The C0-C2 fragment had different effects on the kinetics of nucleotide, ATP, and ADP exchange, increasing the affinity of ventricular myosin for ADP and decreasing the affinity of atrial myosin. The effect of the C0-C2 fragment on the activation of the thin filament depended on the myosin isoforms. Atrial myosin activates the thin filament less strongly than ventricular myosin, and the C0-C2 fragment makes these differences in myosin isoforms more pronounced.

Identification of tephra and its allocation (association) with known eruptive events allows obtainng chronostratigraphic markers, on the basis of which an age scale for dating glacial strata can be developed. To determine the sources of ash in the ice core obtained in 2022 during drilling of glacier in the crater of the Ushkovsky volcano in Kamchatka, the chemical composition of volcanic glass in individual ash particles was analyzed. The accuracy of determination of the volcanic glass composition was verified by analyzing of international standard samples of volcanic and synthetic glass. Based on a comparison of the data we obtained with published data on the composition of tephra glasses from the present-day eruptions in Kamchatka, we determined affiliation of each tephra horizon to specific volcano-source. We have found that the main source of tephra in the ice core of the Ushkovsky Glacier is the Kliuchevskoi volcano, which is the closest and the most productive one among the Kamchatka volcanoes. Ash particles from Bezymyannyi volcano were identified in two horizons. A mixed population of particles was found in one of the horizons, including the ash particles from volcanoes Kizimen, Kliuchevskoi and Bezymyannyi. Analysis of published data on the chronology and distribution of ash plumes from known eruptive events made it possible to confidently correlate the tephra horizon at a depth of 762–777 cm with the initial phase of the eruption of the Kizimen volcano in late 2010–early 2011. Ash from the uppermost tephra buried in the glacier at depths of 89–94 cm belongs to the Bezymyannyi volcano eruption, which the most likely occurred in October 2020. Single particles with rhyolitic composition of glass in the sample from the depth of 348–354 cm may belong to the eruption of the Shiveluch volcano in December 2018. The results of our work can be used on further studying of the ice core from the Ushkovsky volcano, in particular for comparison and correlation with the chronostratigraphic data obtained by glacio-chemical and isotope methods.

В монографии доктора исторических наук, профессора кафедры методики преподавания истории Московского государственного педагогического университета Марины Владимировны Коротковой рассматриваются гендерные проблемы дворянского образования и воспитания, которые актуальны как опыт реализации гендерного подхода. В педагогической системе раздельных учебных заведений дворяне обоего пола получали прекрасное профильное образование, направленное на их гендерные роли в дальнейшей жизни. Безупречность светского образования, крепость родственных и семейных отношений, отточенный этикет и хорошие манеры, правильные отношения мужчины и женщины – вот далеко не полный перечень дворянского наследия, которое стало впоследствии достоянием всего общества и даже сохранилось до сегодняшнего дня. В книге обобщен богатый архивный редкий материал по истории детства и образования дворянских детей в контексте повседневной культуры семьи и закрытых учебных заведений для первого сословия. Дворянское образование рассматривается в историческом и педагогическом аспектах. Книга адресована педагогам, историкам, аспирантам и студентам и всем интересующимся историей образования.

Published: July 2024

Проблематика определения психологического содержания художественной деятельности является актуальной не только для педагогов, психологов, арт-терапевтов. Сложно перечислить все направления профессиональной деятельности, так или иначе имеющие отношение к искусству, точнее, к художественному способу познания. Процессы художественного восприятия, воображения, создания и применения художественных образов, психолого-педагогических практик, основанных на применении художественной деятельности, и их включения в гуманитарные процессы касаются практически всех областей деятельности, среди которых наиболее значимой является социальная (культура, искусство, образование, реклама, политика, имиджирование и т.д.). Предлагаемое в данной книге теоретически глубокое и практически ориентированное осмысление психологии художественной деятельности представлено в интересной и актуальной на данный момент форме создания научно-исследовательской, поисковой образовательной среды. Монография может быть предложена как основная и дополнительная литература студентам, аспирантам гуманитарных вузов, ученым и практикам.
