Authors: Nakaznoy Oleg A. , Tsipilev Alexander A.
Published: January 2023

BACKGROUND: The information about application of hydraulic springs in suspension systems of tanks and self-propelled artillery weapons may be found in domestic scientific and nonfiction literature. In addition, machines, which prototypes were equipped with this type of suspension, are known. For instance, possibility of hydraulic suspension implementation was proven on the T-34 tank prorotype, whereas application of this type of suspension with heavy tanks gave the most prospectivity. Complication of sealing build-up with sufficient life span, development of technologies of metal springs strengthening and shutdown of heavy tanks development did not allowed hydraulic suspensions to become widespread. At present, they are not used at all, whereas methods of analytical calculation are not in public access, despite of the interest of a group of scientists. AIMS: Development of the method of determination of main parameters of suspensions with hydraulic springs and analysis of properties of the T-34-76 Soviet middle tank prototype hydraulic suspension from the point of modern theory of nonlinear suspension systems. METHODS: Justification and confidence of given dependencies for properties calculation, conclusions and recommendations are confirmed with application of strict mathematical apparatus of mechanics, hydraulics and thermodynamics as well as scientifically justified theoretical backgrounds. RESULTS: Historic data on liquids compressibility researches, method of analytical determination of main properties of hydraulic springs with various design schemes, allowing restoring of properties of suspensions of existing tracked vehicles, synthesizing properties of other suspensions and, moreover, estimating reasonability of properties of suspension with hydraulic springs, are presented in the article. According to the method, proposed in the article, properties of the hydraulic spring from the T-34-76 Soviet middle tank prototype, equipped with hydraulic suspension, were restored and analyzed. In addition, suspension properties for the same vehicle were synthesized and used for a comparative analysis. CONCLUSIONS: The information, presented in the article, is helpful for research engineers, interested in study of elastic behavior of liquids in case of their application in suspension systems, whereas the proposed method, allowing synthesis of reasonable properties of hydraulic springs, gives an opportunity to study the ride comfort of tank propotypes, equipped with hydraulic suspension, with a good quality and, moreover, to synthesize hydraulic springs properties according to the demands, given to a design engineer.
The low power diesel-generator unit with electronically controlled fuel injection
Authors: Galiullin Rustam R. , Potapov Viktor I.
Published: January 2023

BACKGROUND: Diesel engines, used in generator units, primarily operate in variable loading conditions. Therefore, their technical and economic performance generally deteriorate when the load decreases. It arises from the diesel engine fuel system feature, where pressure and quantity of the fuel, injected into a cylinder, reduces with the load decreasing. As a result, the injection becomes sluggish, the quality of mixing process and combustion becomes worse.
AIMS: Improvement of effective indicators of the diesel-generator units with electronically controlled fuel injection.
METHODS: Adjustment of operation modes of the diesel engine of the electrical power unit carried out with use of electronically controlled Denso solenoid, connected to the high-pressure fuel pump via an adapter.
RESULTS: Results of the motor testing of the low power diesel-generator unit with electronically controlled fuel feed system are described in the article. The oscillograph charts of valve displacement and solenoid magnet winding current, presented in the article, confirm its operation efficiency. Sharp decrease in boost current at the stage of valve lift can be explained by onset of back EMF. Stable solenoid operation at diesel operation velocity of 30003100 min-1 is achieved by means of boost impulse supply to its winding. The boost impulse is supplied from a voltage upconverter and generated by discharge of preliminary charged booster capacitor.
CONCLUSIONS: Separated fuel feed adjustment in each high-pressure pump section made possible to reduce intersectional fuel feed irregularity to zero. Significant fuel consumption reduction was revealed with the motor testing of the low power diesel-generator unit with electronically controlled fuel feed system (the reduction reaches 10% on low loading operation modes). As mentioned by authors, transition to electronic control of operation modes of diesel engines of autonomous electrical power units does not require major engine design change only to dismantle a mechanical controller and to set an adapter with electronically controlled bypass valve at a section of the high-pressure fuel pump. Electronic control unit supplies current to the valve. For autonomous electrical power units, transition to this control method can be done in typical repair workshop conditions, and an update of one unit (e.g. the KIPOR KDE19AE3) costs 13 950 rubles. By doing so, one electrical power unit may save up to 1191 liters of fuel and more than 63.96 thousands rubles at a cost of 53.7 rubles per liter.

Authors: Mukhametshin Rustam F. , Kovtun Olga P. , Davydova Nadezhda S.
Published: January 2023

BACKGROUND: Assessment of the clinical condition, prediction of risks and possible outcomes during the transfer of newborns remains an important part of the work of transport teams. Respiratory disorders remain a significant indication for transfer to medical organizations of a higher level of care.
AIM: To study the predictive value of the parameters of respiratory support in newborns requiring medical evacuation for the outcomes of treatment.
MATERIALS AND METHODS: The observational, cohort, retrospective study included data from neonatal to patients on ventilators (286 newborns) in the period from August 1, 2017 to December 31, 2018. Anamnesis parameters, intensive care volume, respiratory support settings, and assessments on scales (KSHONN, NTISS, TRIPS) were evaluated. Analyzed: 24-hours mortality, 7 days mortality, hospital mortality, air leakage syndrome. The assessment and comparison of the predictive value of the parameters in relation to the hospital outcomes was performed.
RESULTS: The AUC ROC of SpO2/FiO2 for predicting 24-hours mortality was 0.984 [0.9661.000], which is significantly higher than the ROC of the saturation oxygenation index (AUC 0.972 [0.9490.995], p = 0.004). The area under the ROC of the 24-hours mortality on the TRIPS scale does not significantly differ from the saturation index of oxygenation (AUC 0.972 [0.9490.995], p = 0.113) and the mean airway pressure (AUC 0.943 [0.8841.000], p = 0.107). When predicting 7-day mortality, the saturation oxygenation index has AUC ROC (0.702 [0.5490.854]) significantly lower than AUC ROC for SpO2/FiO2 (0.762 [0.6380.887], p = 0.001). SpO2/FiO2 predicts total mortality with AUC ROC (0.759 [0.6770.841]).
CONCLUSIONS: The mean airway pressure, saturation oxygenation index and SpO2/FiO2 have a high (AUC 0,9) predictive value for 24-hours mortality, while only SpO2/FiO2 reliably predicts total mortality with AUC ROC 0,7.

Introducción: la hipocalcemia por hipoparatiroidismo es la complicación más frecuente tras tiroidectomía total. Un factor predictor importante de hipocalcemia es la parathormona postoperatoria, pero el momento en el que otorga mejores resultados predictivos aún se discute. Objetivo: el objetivo es analizar el valor pronóstico de la parathormona postoperatoria a las 24 horas como indicador de hipocalcemia, en comparación con la seriación de los niveles de calcio. Metodología: estudio observacional retrospectivo y descriptivo de 297 pacientes intervenidos de tiroidectomía total durante ocho años. Los pacientes fueron clasificados en tres grupos de riesgo según la parathormona postoperatoria (alto, medio y bajo riesgo). Para comparar la parathormona frente al calcio postoperatorio como predictor de hipocalcemia, se obtuvieron curvas ROC y áreas debajo de la curva. Resultados: el riesgo relativo de tener hipocalcemia con parathormona ≤15 pg/mL es de 353,4 (p = 0,00). La prueba de parathormona postoperatoria (≤15 pg/mL a las 24 h) obtuvo una sensibilidad del 96,25 % para la detección de hipocalcemia, especificidad del 94,06 % y precisión global del 95,03 %. El grupo de alto riesgo (parathormona ≤15 pg/mL) concentra la mayoría de los pacientes con hipocalcemia, y abarca la totalidad de los casos permanentes. Conclusiones: la parathormona postoperatoria a las 24 horas de la tiroidectomía total es un test con un valor pronóstico considerable, capaz de predecir el riesgo de hipocalcemia postquirúrgica. Se encontró que los pacientes con parathormona >15 pg/mL pueden ser dados de alta de manera segura.

Numerical and Experimental Investigation of Thermal Behaviour for Fast Charging and Discharging of Various 18650 Lithium Batteries of Electric Vehicles
Authors: Kumar Ravindra , Chavan Sandip
Published: January 2023

Fast charging and discharging are keen focus areas of electric vehicles (EVs) in order to reduce vehicle down time and support the variable load requirement. In EVs, mainly lithium batteries with various chemistry such as NCA (nickel cobalt aluminum oxides), LTO (lithium titanate oxide), LFP (lithium iron phosphate), LNO (lithium nickel oxide) and NMC (nickel manganese cobalt oxides) are used as energy storage system. Performance of lithium batteries varies with the chemistry and temperature of batteries along with surrounding conditions. More heat is generated during fast charging and discharging of batteries which lead to high temperature rise and further impact the performance, life and safety of batteries. Thus, it’s essential to study the thermal behaviour for fast charging and discharging of various lithium batteries to provide desired thermal management system for safety and better performance. In this paper, the thermal characteristics of various 18650 lithium batteries including NCA, NMC and LFP are investigated experimentally and numerically from slow charging and discharging loading rate of 0.5C to fast charging and discharging loading rates of 1.5C and 2.5C at different surrounding temperature of 27°C and 45°C. In the numerical investigation, the internal resistance of the batteries is first measured experimentally at various SOCs and battery temperatures, and then the battery surface temperature is determined using an appropriate numerical method for solving the energy balance equation. From slow to fast loading rates at varying ambient temperatures, the numerical study approach presented in this work estimates the battery surface temperature with at least 90% accuracy for the whole duration of the load cycle. The thermal assessment of NCA, NMC, and LFP batteries in this work can help to determine battery management system operating strategies and, ultimately, to develop an appropriate thermal management system.

Published: January 2023

Refrigerating machines are used in many areas to produce artificial cold. In the course of its operation, each refrigeration unit generates a lot of heat by compressing the refrigerant, which is not used in any way in the future, and during condensation is released into the environment in the form of water vapor. The use of chlorine-containing refrigerants destroys the ozone layer. To reduce environmental damage, a water reuse system was created and a technology for using low-temperature heat that is released during the operation of the refrigeration machine was developed. This paper offers various design solutions aimed at the comprehensive modernization of the cooling system of the ice palace "Puck" in Sochi to reduce its impact on the environment. In the course of the research, a refrigeration unit was developed allowing utilization, accumulation, and channeling of condensation heat for the secondary use of thermal energy by other engineering systems at the facility, thereby reducing emissions of harmful substances into the Earth's atmosphere and increasing the technological capabilities of cooling. Methods that allow making the necessary calculations and selecting equipment for the implementation of the developed systems on ice arenas are also proposed.

Traffic congestion and management have posed a major challenge to many cities in the world. Intelligent traffic management system plays an important role in monitoring and enforcing traffic laws with reduced labor. This paper uses vehicle information recognition to identify unpermitted lane shunting at the University of Ibadan main gate. The vehicle recognition system captures three main details of the vehicle; its license plate, make, and colour to ensure the system, which is named UiScope, is robust enough. Machine learning and deep learning algorithms including Convolutional Neural Network (CNN), Support Vector Machine (SVM), and K-Nearest Neighbor (KNN) algorithms are used to train classifiers for vehicle make, license plate, and colour recognition. The captured details are uploaded on a Structured Query Language (SQL) database to create a blacklist of vehicles that are shunted. The querying of the database is used to determine the shunted vehicle. The success rate for plate identification is 92%, character segmentation is 87%, character recognition is 75%, and vehicle colour recognition is 78%.

Published: January 2023

Flexible manipulator is widely used in the implementation of industial robotic due to its advantages such as low weight, low power consumption, higher load capacity, high-speed operation, small actuators and low production costs. However, the position and speed of flexible manipulator system are very difficult to control due to the tip vibration that result in degradation of performance. Modelling and control of a double-link flexible robot manipulator are presented in this study. Controlling the movement of a double-link manipulator, on the other hand, has proven to be a challenging task, especially when a flexible framework is used. Moreover, most double-link flexible manipulator system models are not developed based on real hardware. Hence, this project aims to develop a Solidworks design for double link flexible robotics manipulator (DLFRM) as well as a real hardware prototype. The control position performance of DLFRM was analyzed, and the controllers were tested on a hardware prototype. This project started with a simulation of both controllers, which are PID and FLC. The simulation was designed in Solidworks and exported to Simulink and then converted as Simscape. Then, the hardware for each controller was validated using the control parameter in the simulation. The joints for the robot manipulator were designed in Solidwork and built using 3D printing.

Objectives: Platinum-based compounds (PBC) play an important role in cancer therapy. However, one of the drawbacks of PBC is the occasional occurrence of hypersensitivity reactions (HSR) which can lead to serious consequences. The aim of the study is to estimate the prevalence and evaluate risk factors of HSR to PBC in cancer patients. Methods: A case-control study of patients who received any PBC for the management of non-haematological cancers from 2013 to 2020 at Sultan Qaboos University Hospital, Oman. Data regarding demographic features and diseases and treatment details were collected from the hospital’s electronic patients record. We quantitatively described the data, and Student’s t-test and Wilcoxon Man-Whittney tests were used to detect significant differences. Results: A total of 38 cases and 148 matched controls were studied. The prevalence of HSR to PBC in our cohort was 4.7% (95% confidence interval: 3.33%-6.37%), more with carboplatin compared to cisplatin and oxaliplatin. In our study, female gender (p=0.032), concomitant taxanes (p=0.002) and concurrent radiation (p<0.001) were significant predictors of HSR to PBC. The majority of reactions were of mild to moderate severity and the rechallenge rate after HSR development was 13%. Conclusion: HSR to PBC impact therapy decisions and understanding the risk factors are important to improve treatment outcomes in cancer patients.

A magyar nyelvű Domonkos-kódex tizenegy lapnyi, két blokkban (171/11–176/8; 299/18–305/12) elhelyezkedő részletének latin forrásaként Katona (1906) az itáliai hagiográfus, Petrus Calus (ol. Calo) Szent Domonkosról (1340-ben) írt legendáját azonosította. Később azonban az a vélemény erősödött meg, hogy Calo műve nem lehetett a közvetlen forrás, mert a fordítás jelentősen eltér attól.A cikk szerzői – egy, a Petrus Calo szövegének kritikai kiadásában (Simon Tugwell OP 1997) feltüntetett olvasati variánsból kiindulva – arra a megállapításra jutnak, hogy a magyar fordítás tényleges forrása a fenti lapokon valószínűleg a Velencében 1494-ben publikált domonkos rendi breviárium volt.

A kelet- és délkelet-európai országokban élő német nyelvi kisebbség körében végzett nyelviattitűd-kutatás még nem tekint olyan régi hagyományokra vissza, mint Németország, Ausztria, valamint a németnyelvű Svájc esetében. A kisebbségek körében végzett nyelviattitűd-kutatások eredményei bepillantást engednek abba, hogy a kisebbségi nyelvet aktívan vagy passzívan használók – jelen tanulmány esetében az idős magyarországi németek – hogyan érzékelik a környezetükben hallott német nyelv különböző változatait, hogyan vélekednek a német nyelvi változatok használatáról, a magyarországi német nyelvjárások generációkon átívelő eróziójáról, illetve hogyan értékelik a német nyelv köznyelvi, regionális és lokális változatait. A tanulmány a kétnyelvű (magyar-német) adatközlők nyelvi önmeghatározásából kiindulva a német nyelvi attitűdjük affektív és konatív komponenseit vizsgálja.

В работе проведено исследование влияния режимов аддитивной электродуговой наплавки и термического цикла на микроструктуру, микротвердость и механические свойства стали ER309LSI (Св-07Х25Н13) при пониженной температуре. Установлено, что в качестве оптимального режима печати для исследуемой стали нужно выбирать режим с погонной энергией наплавки порядка 562 Дж/мм, т.к. в данном случае образуется наименьшее количество σ-фазы, негативно влияющей на свойства стали. При наплавке необходимо обеспечить неполное остывание предшествующего слоя для обеспечения оптимальных параметров структуры. Показано, что при понижении температуры наблюдается возрастание предела прочности и текучести и уменьшение относительного удлинения материала.

Published: January 2023

Capillary chromatographic columns with different stationary phases were studied in order to compare their ability to estimate purity of isopropyl alcohol obtained by hydrogenation of acetone. The study was performed with the columns based on polyethylene glycol 20 M terminated with 2-nitroterephthalic acid (PEG20M/FFAP); poly(1-trimethylsilyl-1-propyne) (PTMSP032); and trifluoropropyl (25 %) methyl silicone elastomer (SKTFT 50X). A comparison of the measurement time, asymmetry factors (As) for components of the mixtures, and resolution (Rs) for the pairs of compounds acetone/isopropanol and isopropanol/internal standard gave grounds to choose a capillary column PEG20M/FFAP. A technique was developed for measuring the weight fractions of acetone and isopropanol using the method of internal standard in the gas phase. n-Butanol served as the internal standard. The detection limit was found to be 1.45 for acetone, 1.43 for isopropanol, and 1.28·10–12 g/s for n-butanol. Relative standard deviation (the recurrence factor) did not exceed 4.3 % at a confidence level P = 0.95.

The full text of the article will be published in the English version of the journal "Catalysis in Industry" No. 1, 2023.

The iron-based catalysts were prepared via wet-impregnation method. The composition of the final iron catalysts, regarding to the weight ratio is as follow 14%Fe/γ-Al2O3, 14%Fe/3%Cu/γ-Al2O3, 14%Fe/3%Sn/γ-Al2O3 and 14%Fe/3%Cu/1%Sn/γ-Al2O3. The catalysts were characterized using XRD, ICP, BET, H2-TPR, FE-SEM and EDX techniques. The catalytic activity was evaluated in a fixed bed reactor under 20 bar of pressure, H2/CO = 1, GHSV = 2 L/(gcat·h), in the temperature range of 270–300 °C. Then, the effect of temperature and promoters (Cu and Sn) on the catalyst performance were investigated. CO conversion and product selectivity were also calculated using the results of GC. The results showed that the Cu and Sn promoters increased the reduction rate of Fe2O3 by providing H2 dissociation sites. Higher temperatures were also shown to change the CO conversion and product selectivity. The selectivity of both methane and C2–C4 hydrocarbons decreased while the selectivity of C5+ increased because of simultaneous use of Cu and Sn for promoting iron catalyst. Sn promoter increased FT and WGS activities.
De la trama al espacio. Desarrollo y aplicación de la retícula en el trabajo de Donald Judd
Authors: Llamazares Blanco Pablo
Published: January 2023

Al margen de la expresión escultórica que Donald Judd desarrolla desde la esfera minimalista, el autor estadounidense explora otras vías creativas, como el trabajo con tramas desde lo superficial. A continuación, se analizan los términos en los que Judd desarrolla ese concepto, y la manera en la que lo aplica en sus creaciones espaciales. Así pues, se acota el estudio a trabajos realizados por el autor a partir de los ochenta, y se analizan de acuerdo con los principios organizativos que se emplean en cada caso. Principios que se sustentan en la aplicación de una retícula como medio en la articulación espacial, y que se analizan para descubrir relaciones entre ellos. Con el estudio se descubre una estrecha conexión entre todas las creaciones analizadas, que se inician con sus series de grabados en el arte, y que se trasladan luego a proyectos e intervenciones en la arquitectura. En definitiva, se detecta la importancia que Judd concede a la retícula en las áreas creativas en las que trabaja en un momento concreto de su carrera, y cómo consigue traducirlo espacialmente, ejemplificando el salto de la trama al espacio.

It’s Not About the Burqa: Transversing Heterotopia and Hypomnemata in Muslim Women’s Life Narratives

Authors: Joseph Aswathi Moncy
Published: January 2023

Muslim women who are forcibly displaced from their homophobic parent culture are further oppressed within the structures of Islamophobia in the host culture. Discursive re-imaginations based on their Islamic authenticity have skewed them as either veiled or unveiled women from other homogeneous ethnic cultures. Such cursory representations have cemented perceptions about them as outsiders and so a source of constant threat. Therefore, the main objective of this article is to aid discursive reconfigurations of partial representations affecting transculturally or forcibly displaced Muslim women at the intersections of racial, gender or religious persecutions.

             Through a reading of the life-narratives by similarly displaced Muslim women in the anthology It’s Not About the Burqa, this article examines two key questions: 1) How do these women negate discursive conceptions of single stories? 2) How do they reach a unique discourse that addresses such partial representations? The article proposes heterotopia and hypomnemata as two transversal possibilities. Heterotopias are worlds within worlds which mirror what is outside. They can contain differences and undesirable bodies. Whereas hypomnemata refers to personal notes used for later reading and meditation. There has been little work bringing together the transcultural and the transversal. While the transcultural is a system of thought that conceives of cultures as an ongoing flux of confluences,[1] transversality endorses plural possibilities. It offers tools to deterritorialize closed logics.[2] This article therefore calls for revisiting the collaborative dynamics of these concepts as contested through the life-narratives of displaced Muslim women.

Analysis of Patents Held by Korean Beauty Masters
Authors:   The Korean Society of Beauty and Art, Lee Su-Hee
Published: January 2023

There has been a necessity of studies on the value and practicality of beauty-related patents in a real world.
Therefore, this study attempted to improve the percentage of patent evaluation in the conditions for the document screening needed to choose Korean beauty masters and classify patent, design and utility model registrations and make suggestions, focusing on 10 Korean beauty masters. Among numerous patents registered at the Korean Intellectual Property Office (KIPO), those whose information is disclosed online were analyzed. Then, the percentage of the evaluation of patent and design registrations and its necessity were investigated. Among the 10 Korean beauty masters’ intellectual property rights, a total of 57 patents, designs and utility models were examined. Specifically, hair-related cases (42 registrations) were the highest, followed by tool-related cases (10 registrations), cosmetics (4 registrations) and others (1 registration). According to the document screening, ‘sharing of skills’ was 22%, and patents, utility models, books and academic papers were 12 points.
In fact, it accounts for a great portion because a point is given per achievement.

The study considers some aspects of the development of new stimuliresponsive materials capable to reversible deformation under an electric field due to the Maxwell pressure. To increase the response of the material to an external stimulus, an approach of polymer composites formation was chosen. Particles of various nature and shape were considered as fillers: powders of iron, montmorillonite and cellulose. Composite elastomeric materials based on polydimethylsiloxane with a low filler content of 5 wt% have been obtained. The morphology of the filler particles was confirmed by electron microscopy. Mechanical properties of the materials in uniaxial tests were studied. The Young’s modulus and constants for the 3-parameter Yeoh model in the range of deformations up to 800 % were determined. The electrophysical properties of the materials, as well as their response to an electric field at different strengths of 0.84 and 2.5 kV/mm have been studied. The effect of the filler nature on the conductivity and permittivity of composite materials was revealed. The data of mechanical and dielectric studies indicate that the filler concentration is below the percolation threshold for all composites. The composite with cellulose exhibits the greatest response to an external stimulus over the considered materials, which is determined by the balance of two factors: the value of Young’s modulus and the values of electrophysical characteristics. Directions for further research were determined and the prospects for the dielectric elastomers creation with predetermined properties were briefly discussed
