Authors: Lotf Fatemeh , Ziamajidi Nasrin , Abbasalipourkabir Roghayeh , Taghi Goodarzi Mohammad , Soleimani Asl Sara
Published: November 2021

Background: Hyperglycemia damages various tissues such as the testes through oxidative stress and inflammation, which can eventually lead to infertility.
Objective: Garlic extract effects on the testicular tissue of diabetic rats were investigated.
Materials and Methods: In this experimental study, 36 male Wistar rats (8-wk old, weighing 230-300 gr) were randomly divided into 6 groups (n = 6/each) including; C: control rats, G: received 0.4 gr of garlic extract/100 gr body weight, D1: Streptozotocin-induced-diabetic rats or type 1, D1+G: D1 rats that were treated with garlic, D2: Streptozotocin + nicotinamide-induced-diabetic rats or type 2, D2+G: D2 rats treated with garlic. At the end of the study, serum testosterone was assayed by ELISA. Also, sperm quality and quantity were evaluated. For determination of oxidative stress status, total antioxidant capacity, total oxidative status, lipid peroxidation, and thiol groups were assayed in the testis tissues of the rats by colorimetric methods. Also, inducible nitric oxide synthase (iNOS) gene expression and the protein level of interleukin-1-1β (IL-1β) were determined by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively.
Results: In diabetic rats, glucose, total oxidative status and lipid peroxidation, iNOS gene expression, and IL-1β were higher than in non-diabetic rats, whereas testosterone, total antioxidant capacity and thiol groups, and sperm quality were significantly lower compared with control rats. These alterations were normalized by garlic intervention.
Conclusion: In diabetic rats, garlic was associated with reduced glucose, oxidative stress, IL-1β, and iNOS gene expression and increased testosterone and sperm quality. So, the results suggest that garlic can reduce the severity of damage in testicular tissues of diabetic rats through its hypoglycemic, antioxidant, and anti-inflammatory properties.

Delay time of gases's catalytic heterogeneous ignition on various sizes's catalyst particles
Authors: Kalinchak V.V. , Chernenko A.S. , Fedorenko A.V. , Roziznaniy M.V.
Published: November 2021

In this work, catalytic ignition delay time of combustible gas's small impurities in air on a spherical metal particle of various diameters is analytically determined by the example of gas-air mixtures's flameless combustion with hydrogen impurities on a platinum particle. It is shown that stable flameless combustion is observed after an induction period for particles of a certain range. It has been established that catalytic ignition time of gases is divided into three stages: 1. inert heating, the duration of which still depends on the combustible gas concentration; 2. the stage of self-acceleration and catalyst temperature rise during the course of the catalytic reaction in the transition region; 3. stage of diffusion inhibition and reaching stable catalytic combustion. The characteristic relaxation time was used in a dimensionless form. To determine the duration of the second stage, a modified Frank-Kamenetsky approach is applied. The duration of diffusion inhibition stage in the dimensionless form is practically independent of catalyst particle's diameter, although the catalytic combustion temperature decreases with an increase in the catalyst diameter. Heat transfer by radiation, the role of which increases with the growth of the catalyst size, is included in the effective heat transfer coefficient, which allows maintaining the classical ideology to solving the problem of the induction period.

Technological overcoming of the potential threat of a decrease in the quality of radiation monolithic structures of protective shields, which are under constant influence of ionizing radiation (due to radiation embitterment) is one of the most urgent tasks of ensuring protection against radiation exposure.

The aim of the work is to carry out a comparative analysis of the quality (in terms of radiation protection) of monolithic and granular protective screens. In contrast to monolithic prototypes, granular conglomeration has clear advantages, which are to avoid destructive processes of radiation embitterment, simplify replacement and handling (compaction and compaction), and disposal. It is important to emphasize that the protective properties of granular screens hardly differ from their monolithic counterparts, and the economic advantages of the corresponding technologies are significant at the same time. The material provided is actually the formulation of the problem on the theoretical substantiation of the advantages of using granular materials (in comparison with monolithic ones) in radiation protection technologies based on analysis as physical mechanisms and form factors of interaction neutron and gamma radiation with a substance with a developed morphology on a micro-scale.

Authors: Zahrai L. , Fedoruk O.
Published: November 2021

The paper focuses on the problem of leadership. The gender’s specificity issue of leadership is being analyzed. The transformational leadership model of the justification is presented. The purpose of the article is to perceive the «leader» students concept in the picture of the world in gender’s context. Different leadership theories are analyzed. Three key approaches to leadership interpretation are particularly described: personality features, situation interaction, behavior. The modern leadership theories are analyzed. These theories are methodological basis for transformational leadership model formation. Indicators of the transformation model are being differentiated: interaction with the followers, but not the subordinates; the followers goals transformation; stimulation of their self-development and their result achievements. The research methodology for the students leadership concept is described. The methods applied: uncompleted sentences; psychosemantic differential. While considering the picture of the world, the «leadership» concept content among most students is masculine. Leadership concept includes characteristics such as: dominance, power, success and the ability to be the first and to lead. Personal characteristics in particular emotional and voluntary self-regulation, organizational, mental abilities, moral and communicative features are not important. Gender specificity in the students «leadership» concept content is differentiated. The psychosemantic constructions of power-dominated relations, competition and domination are dominated in the men. The key characteristics of the psychosemantic content of women’s leadership models are the ability to lead, success and dominance. The stereotyped level of the leadership model formation is typical for most students.

Published: November 2021

In the article are represented the results of an empirical study of the relationship between meaningful life orientations and motivational readiness of students for professional activity. It was found that the leading orientation of the studied students, which is most pronounced at a high level, is the focus on interaction and cooperation, due to the interests of cooperation, constructive interpersonal communication, the needs of joint activities. It is noted that the focus on cooperation of students with other people reflects their motivation to communicate as a process when it is communication, interaction, and not the specific results of such activities that matter. The students found a predominance of the average level of life aspirations, which can be explained by their mediocre self-confidence, insufficient ability to set life goals according to their own capabilities, as well as the average level of life achievements due to average and low assessment of their ability to manage their own lives. It has been shown that the global Covid-19 pandemic has contributed to the actualization of those needs that are limited or even impossible due to total lockdown. It was found that the motivational structure of students is dominated by high levels of all indicators of life orientation: livelihood, comfort, communication, and «work» orientation, which determine the motivational orientation of students to professional activities in the form of general and creative activity and social utility. At the same time, the developmental motives of professional readiness for activity («working» orientation) of the studied students are higher in comparison with the motives of maintenance (general life orientation). The strongest connection between the indicators of meaningful life orientations is found with the need for recognition, with the need for self-expression and with the tendency to affiliation. The general life orientation of students depends mostly on life support and communication, and the «work» orientation — on general and creative activities.

Wpływ działalności bobrów na lokalne procesy fluwialne w wybranych rzekach Równiny Łowicko-Błońskiej
Authors: Kobojek Elżbieta
Published: November 2021

Artykuł przedstawia wpływ działalności bobrów na przebieg procesów fluwialnych w rzekach nizinnych. W 1983 r. bobry sprowadzono do środkowego odcinka Rawki, a w 1996 r. ślady działalności zwierząt zaobserwowano w Bzurze. W ogólnych pracach zoologicznych podkreślany jest fakt mieszkania przez bobry w żeremiach. Natomiast zebrany materiał wskazuje, że współcześnie w Polsce Środkowej bobry mieszkają głównie w norach wykopanych w brzegu. Szczegółowe badania przeprowadzono w wybranych odcinkach rzek nizinnych w obrębie Równiny Łowicko-Błońskiej: w uregulowanym korycie dużej rzeki (Bzura), w meandrującym korycie średniej rzeki (Rawka) i uregulowanym korycie małej rzeki (Igla). Największy wpływ na procesy fluwialne miały wybudowane tamy i stawy na małej rzece. Tylko w małych rzekach i ich dolinach, działalność bobrów powoduje zatrzymanie dużej ilości wody i przyczynia się do lokalnego wzrostu jej poziomu. W dużych rzekach, środowisko jest przekształcone tylko lokalnie w sąsiedztwie brzegu z norami. Działalność bobrów w rzece meandrującej ogranicza się do zmniejszenia prędkości przepływu wody i osłabienia procesów erozji bocznej, często tylko w jednym zakolu meandrowym. W jednym przypadku działalność bobrów przyspieszyła przecięcie szyi meandrowej i utworzenie starorzecza. W dużej, uregulowanej rzece w dwóch przypadkach zaobserwowano inicjalną erozję boczną.

Authors: Mandal Ram Krishna
Published: November 2021

Introduction: Population growth is critical for sustainable development in the true sense. Overpopulation indicates a scenario in which the population of a living species exceeds the carrying capacity of its ecological niche. So far, India's family planning programmes have seen only limited success because the programmes have not tackled the issue in a holistic way. Methodology: The paper aims to examine the trend and effect of population in India. This study is descriptive in nature based basically on data of secondary sources collected from government offices, books, articles, various census reports, and websites published in different times. Result and Discussion: India occupies 2.4 per cent of the world's land area and supports over 17.5 per cent of the world's population. There are some vital impacts of overpopulation such as Food Shortage, Deforestation, Water shortage, Energy, Extinction, etc. Conclusion: Stabilising population is an essential requirement for promoting sustainable development. India's population policy needs to be based on concrete measures that not only help to solve our population problem but also helps the poor to improve their lives in tangible and meaningful ways.

Este artículo presenta la investigación realizada sobre el Logro de competencias durante el proceso de aprendizaje en los tiempos del COVID-19 en la Educación Básica peruana, la cual ha pasado de una modalidad presencial a una de distancia. Para la variable Logro de competencias se han considerado cuatro dimensiones: la cognitiva, la comunicativa, la social y la ética. Se desarrolló dentro del enfoque cuantitativo; su nivel fue descriptivo explicativo, de diseño no experimental, transaccional exploratorio, aplicándose una encuesta a 212 docentes de una red educativa de Lima Metropolitana. El objetivo fue analizar el factor predominante que limita el logro de las competencias priorizadas. Aplicando la regresión logística, desde la perspectiva de los docentes se logró determinar que la retroalimentación (0,589) y la evaluación del portafolio (0,694) son factores que limitan el logro de las competencias, pues muestran valores de significancia mayores que la teórica (α = 0,05), mientras que el rol de la familia (0,00) no limita este logro. El docente, siendo mediador del aprendizaje, debe fomentar el desarrollo de competencias. Factores como la retroalimentación y la evaluación del portafolio de evidencias deben tener significancia en sus estudiantes; pero en esta investigación son más bien factores que están limitando el logro de competencias.

Published: November 2021

One of the intriguing recent results in the field of high-entropy alloys is the discovery of single-phase equiatomic multi-component Laves intermetallics. However, there is no clear understanding that a combination of chemical elements will form such high-entropy compounds. Here we contribute to understanding this issue by modifying the composition of duodenary TiZrHfNbVCrMoMnFeCoNiAl (12x) alloy in which we recently reported the fabrication of hexagonal C14 Laves phase. We consider three alloys based on 12x: 7x=12x-VCrMoMnFe, 12x+Sc, 12x+Be and observe that all of them crystalize with the formation of C14 Laves phase as a dominant structure. We report that 12x+Be alloy reveals single-phase C14 structure with very high concentration of structural defects and ultra-fine dendritic microstructure with almost homogenous distribution of the constituted elements over the alloy matrix. The 7x and 12x+Sc alloys contain C14 as a main phase and unknown impurity phases. To characterize the materials, we examine their heat capacity, electrical conductivity and magnetic properties. The measurements reveal that the Laves phases are Curie-Weiss paramagnets, which demonstrate metallic conduction; 7x and 12x alloys also reveal a pronounced Kondo-like anomaly. Analysis of experimental data as well as ab initio calculations suggests that chemical complexity and compositional disorder cause strong s-d band scattering and thus the rather high density of d-states in the conduction band. Analysis of the results suggests that the mechanism of Laves phase formation in multicomponent multi-principal element metallic alloys is may be the same as in polydisperse hardspheres mixtures. Another important conclusion is that the configurational entropy is a negligible factor in the stabilization of multi-element Laves phases.
Rotating Minimal Thermodynamic Systems
Authors: Bormashenko Edward
Published: November 2021

Minimal rotating thermodynamic systems are addressed. Particle m placed into the rotating symmetrical double-well potential (bowl), providing binary logical system is considered. The condition providing the transfer of the particle from one frictionless half-well to another, and in this way possibility to record 1 bit of information is derived. The procedure of recording turns out to be irreversible; it is impossible to return the particle to its initial state under rotation about the same axis. The same rotating double-well system exerted to the thermal noise is considered. Minimal rotating thermal engine built of the rotating chamber, movable partition and the particle confined within the chamber is treated. Rotation of the system displaces the partition; thus, enabling erasing of one bit information. Erasing of 1 bit of information is due to the inertia (centrifugal force) acting on the partition. Isothermal expansion of the “minimal gas” expectedly gives rise to the Landauer bound. Compression of the “gas” with the rotation around the same axis is impossible and demands the additional axis of rotation. The interrelation between the possibility of recording/erasing information and the symmetry of the system is considered.
On the Arrangement of Pentagonal Columns in Tetragonal Tungsten Bronze-Type Nb18W16O93
Authors: Krumeich Frank
Published: November 2021

The evaluation of HAADF-STEM images of a sample with the composition Nb18W16O93 provided new insights in its real structure. The basic structure comprises an intact octahedral framework of the tetragonal tungsten bronze (TTB) type. The partial occupation of the pentagonal tunnels (PT) by metal-oxygen strings determines the oxygen to metal ratio (O/SM with M = Nb,W). For a large area, the O/SM was determined to be 2.755 which is smaller than the value of Nb18W16O93 which is O/SM = 2. 735. To a large extent, the threefold TTB superstructure structure of Nb8W9O47 with a high oxygen content is present (O/SM = 2.765). In addition, a new fourfold TTB superstructure was found in small domains: Nb12W11O63 with an O/SM = 2.739 obviously accommodates a part of the sample’s metal excess compared to the stable phase Nb8W9O47.

In the article, were checked influences of microaeration, pH, and VSS (Volatile Suspended Solid) for sour cab-bage anaerobic digestion. Results fermentation of sour cabbage under the condition of small oxygen addition are presented in this research can be classified as dark fermentation or hydrogenotrophic anaerobic digestion. The investigations were carried out for two concentrations 5 g VSS /L and 10 g VSS /L of sour cabbage at pH 6.0. The oxygen flow rates (OFR) for 5 g VSS /L were in the range of 0.53 to 3.3 mL/h for obtaining 2% to 8% of oxygen. In cases of low pH and microaeration, ethylene production was observed at a level below 0.05% in biogas. The highest volume of hydrogen for 5 g VSS/L was obtained for flow rate 0.58 O2 mL/h, giving hydrogen concentration in biogas in the range of 0 to 20%. For VSS 5 g/L and oxygen flow rate 0.58 mL/h; 0.021 L of hydrogen is produced per gram of VSS. In this case, VSS 10 g/L and oxygen flow rate 1.4 mL/h at pH 6.0, 0.03 L of hydrogen is generated per gram. Microaeration from 0.58 mL/h to 0.87 mL/h was propitious for hydrogen production at 5 g VSS/L of sour cabbage and 1.4 mL/h for 10 g/L. Another relevant factor is the volatile suspended solid factor of sour cabbage that caused optimal hydrogen production at VSS 89.32%.

Published: November 2021

In all areas of medicine, especially in radiology, computers are increasing year by year. Filmless radiology, speech recognition software, electronic application forms, and teleradiology are recent developments that have greatly improved radiologists' performance. This research explores radiology software trends, predictions, and the challenges posed by informatics and historical trend analysis. The rationale behind this research is that information technology (IT) is overgrowing almost every day. We must continuously seek new ways to apply IT to make more use of resources. Consequently, IT becomes increasingly crucial to radiology organizations' innovative thinking, workflow, and business models. This study aimed to analyze all radiology software publications in the Science Citation Index (SCI). From 1991 to July 2021, SCI was used to search for publications systematically. We have also widely used this historical method in radiology software research. The findings and discussions are base on an assessment of trends, predictions, contributions, and challenges in radiology software, and we are exploring radiology software with six evolutionary stages. The gift of this research is that radiology managers realize that the use of new information technologies is closely related to survival in a competitive environment. Radiology companies can review these new technologies to develop more innovative business models and services to improve operational deficiencies.

Published: November 2021

The innovation driven Industry 5.0, in agreement with Industry 4.0, leads to consider human in a prominence position as the center of manufacturing field. This pushes towards the hybridization of manufacturing plants promoting a fully collaboration between human and robot. Furthermore, the new paradigm of "human centred design" and "anthropocentric design" allows enabling a synergistic combination of human and robot skills. However, properly collaborative workplaces are currently very few. Industry is still not confident, and systems integrators hesitate to venture into Human-Robot Collaboration (HRC). Despite the effort in collaborative robotics, a general solution to overcome the current limitations in designing of collaborative workplaces still misses. In the current work, a Knowledge-Based Approach (KBA) is adopted to face collaborative workplace designing problem. The framework resulting from the KBA allows developing a modelling paradigm that enable to define a streamlined approach for the layout designing of a collaborative workplace. Finally, a what-if analysis and a ANOVA analysis are performed to generate and evaluate a set of scenarios related to a collaborative workplace for quality inspection of welded parts. Facing the high complexity and multidisciplinary of HRC can be conveyed to develop a general design approach aimed at overcoming the difficulties that limit the spread of HRC in the manufacturing field.

Published: November 2021

The article considers the features of the method of research of fuel economy and environmental performance of vehicles with engines converted to run on gas fuel, which are equipped with a thermal training system based on a thermal accumulator phase transition, which is based on the implementation of system interaction of three interconnected components: information, analytical and energy. The schematic diagram of the system of thermal preparation and the information system of estimation of ways of maintenance of thermal preparation of vehicles in the conditions of operation by means of system of thermal preparation on the basis of an onboard complex (Intelligent transportation system) are presented. The peculiarity of the proposed system is that the subsystems create a common information field of the vehicle monitoring system with the heat treatment system, but operate separately from each other, based on the characteristics of the tasks they perform. Improved is the method for determining and calculating fuel consumption and emissions in exhaust gases of vehicles with engines converted to run on gas fuel, equipped with a thermal accumulator phase transition in the processes of pre-start and post-start heat treatment based on the selected model of the engine "Neutralizer". To ensure thermal preparation of vehicles with engines converted to run on gas fuel, equipped with a thermal training system based on a thermal accumulator of the phase transition, a cycle of thermal preparation in operating conditions has been developed. The influence of the thermal preparation system with the heat accumulator of the phase transition of a vehicle with an engine converted to run on gas fuel on the fuel efficiency indicators and environmental indicators in the pre-start and post-start-up processes is established.

Published: November 2021

The paper deals with the issues of reliability of piston materials in the process of increasing engine power. It is precisely the increase in the liter power of engines while ensuring environmental and economic requirements that is today one of the main areas of work in engine manufacturing. Studies have shown that material creep has significantly affects on the reliability of internal combustion engine parts. The most thermally loaded engine element is a piston. The main critical areas for it can be identified: the edge of the combustion chamber, the area of the piston rings and the piston skirt. The appearance of seizures on the piston skirt is sometimes observed even during the engine initial tests at the engine power increasing. Thus, we can speak about the relevance of the problem of identifying the reasons for reaching the critical state of the piston material. Based on these data, it becomes possible to develop measures to ensure the reliable operation of the piston. Among the most common materials for the manufacture of pistons are aluminum alloys AL25 and AK4. The chemical composition of these alloys varies considerably. The study obtained coefficients for calculating the creep rate for these materials. The identification of the calculation of the creep deformation of aluminum alloys at different stress levels, for different temperatures is carried out. The upper boundary of the region of model adequacy in terms of temperatures and stresses is determined. The creep rate of aluminum alloys is analyzed at different temperatures.

Adult Soft-Tissue Sarcomas of the Extremities

Published: November 2021

➤ Soft-tissue sarcomas (STS) in adults comprise a heterogeneous group of tumors of mesenchymal origin that share similar biological patterns of local tumor growth and metastatic dissemination.

➤ The judicious use of imaging studies, biopsy techniques, and pathological evaluations is essential for accurate diagnosis and for planning treatment strategy.

➤ Wide local resection and radiation therapy form the cornerstone of management of high-grade STS. The role of adjuvant radiation therapy is questionable in the management of small (≤5 cm) superficial lesions that can be resected with negative margins. Chemotherapy given to patients who have nonmetastatic, high-grade STS results in varying benefit in terms of local tumor control and overall survival.

➤ Coordinated care by a multidisciplinary team of trained surgeons, medical oncologists, radiologists, radiation oncologists, and pathologists has been documented to improve local tumor control and the overall survival of patients with STS.

➤ Although considerable progress in tumor diagnostics and targeted therapies has been made over the past 2 decades, recommendations and controversies relating to tumor imaging and margins of resection have not changed.

Previously, we and other investigators have demonstrated that phosphorylated microtubule-associated protein 4 (p-MAP4) impacts myocardial hypertrophy and ischemic heart failure. However, the detailed mechanism behind this remains under elucidated. Published studies have suggested that impaired mitophagy contributes to hypoxia-induced myocardial damage, hence the involvement of p-MAP4 in mitophagy in cardiomyocytes was investigated. The results herein revealed that there was increased degradation of mitochondria, accumulated mitophagosomes and disrupted autophagic flux in both neonatal and adult ones of MAP4-knockin (KI) mice. This indicated that p-MAP4 persistently degraded mitochondria through activating mitophagy. Next, Tom70 was found as the importer of p-MAP4 in the context of mitochondrial translocation. And, the LC3-interacting region (LIR) motif (47–50aa) caused p-MAP4-induced mitochondrial engulfment, and the ubiquitin-interacting motif (UIM) domain determined the characteristics of p-MAP4-induced mitophagosomes, which were structure and membrane potential-independent. Moreover, p-MAP4 enhanced hypoxia-induced mitophagic flux impairment, and p-MAP4 LIR (47–50aa) mutation decreased hypoxia-induced autophagy both in MAP4 knockout and wildtype cardiomyocytes. Overall, this study identified that p-MAP4 as a novel mediator and cargo receptor in mitophagy, and that the degradation of the MAP4 PJ domain as a promising therapeutic target for improving the cardiac function of hypoxia-related heart failure or cardiac remodelling.

Background

Drugs and substance use-related effects have become a major issue globally. The energetic youth who contribute meaningfully to national development are the most affected population by this social menace. This study aimed to examine the knowledge and perception of the youth on drugs and substance use-related effects on the lives of drug users.
Methods

The study used a qualitative approach to explore the drivers of drugs and drugs and substance use among the youth in the Kwabre-East Municipality of the Ashanti Region of Ghana. The purposive technique was used to select 35 participants based on a set of inclusion and exclusion criteria. The data were gathered through focus group discussions and interviews in the Twi language and audio-recorded. Data were transcribed from Twi to English in a written form. The data were categorized into themes based on similarities and differences. Thematic analysis was used to analyze the data. The emerged themes have been presented as main findings, which are supported by quotations from the participants.
Results

The study identified that substances commonly used by the youth were alcohol, tramadol, gasoline product, glue, and marijuana. Again, it was found that peer influence, poor parental control, and loss of a job (poverty), perceived academic enhancement, and imitation of role models were factors that caused drugs and substance use among the youth. In addition, the following were identified in terms of the effects: mental illness, cardiovascular conditions, family exclusion, insecurity, and stigmatization.
Conclusion

The initiation and implementation of drug preventive interventions by relevant stakeholders are crucial in preventing the commencement of any undesirable behaviour among the youth as far as drugs and substance use is concerned.
