New insights into the role of porous microstructure on adiabatic shear localization
Authors: Vishnu A. R. , Marvi-Mashhadi Mohammed , Nieto-Fuentes Juan Carlos , Rodriguez-Martinez Jose
Published: July 2021

This paper provides new insights into the role of porous microstructure on adiabatic shear localization. For that purpose, we have performed 3D finite element calculations of electro-magnetically collapsing thick-walled cylinders. The geometry and dimensions of the cylindrical specimens are taken from the experiments of Lovinger et al. (2015), and the loading and boundary conditions from the 2D simulations performed by Lovinger et al. (2018). The mechanical behavior of the material is modeled as elastic-plastic, with yielding described by the von Mises criterion, an associated flow rule and isotropic hardening/softening, being the flow stress dependent on strain, strain rate and temperature. Moreover, plastic deformation is considered to be the only source of heat, and the analysis accounts for the thermal conductivity of the material. The distinctive feature of this work is that we have followed the methodology developed by Marvi-Mashhadi et al. (2021) to incorporate into the finite element calculations the actual porous microstructure of 4 different additively manufactured materials --aluminium alloy AlSi10Mg, stainless steel 316L, titanium alloy Ti6Al4V and Inconel 718-- for which the initial void volume fraction varies between 0.001% and 2%, and the pores size ranges from ≈ 6 µm to ≈ 110 µm. The numerical simulations have been performed using the Coupled Eulerian-Lagrangian approach available in ABAQUS/Explicit (2016) which allows to capture the shape evolution, coalescence and collapse of the voids at large strains. To the authors' knowledge, this paper contains the first finite element simulations with explicit representation of the material porosity which demonstrate that voids promote dynamic shear localization, acting as preferential sites for the nucleation of the shear bands, speeding up their development, and tailoring their direction of propagation. In addition, the numerical calculations bring out that for a given void volume fraction more shear bands are nucleated as the number of voids increases, while the shear bands are incepted earlier and develop faster as the size of the pores increases.
Associations with LGBTQ+ mental health disparities during the COVID-19 pandemic
Authors: Victor Sarah E. , Trieu Terry Huong , Seymour Nicole
Published: July 2021

The COVID-19 pandemic has created tremendous, and unequal, burdens on mental and physical health throughout the United States. Prior work suggests that LGBTQ+ individuals have experienced disproportionate harms during the COVID-19 pandemic, but potential mechanisms underlying these disparities remain unclear. In a large (N=893) sample of US LGBTQ+ adults, we examined four theoretically derived risk factors as potential contributors to depression, anxiety, and suicidal ideation during the summer of 2020. Stressors and disruptions due to the COVID-19 pandemic were common, with over 25% of participants experiencing changes in their living situation, 40% reporting interruptions in health care access, and high levels of stress due to social isolation, financial concerns, and increased mental health symptoms. We found that social disconnection, disruptions in health care, financial strain, and efforts to avoid disclosing one’s sexual orientation or gender identity at home were each associated with poorer mental health, with the largest effects evident for identity disclosure avoidance. Transgender and non-binary adults reported poorer mental health overall, but gender identity did not moderate the effects of other tested risk factors. Results highlight the importance of considering LGBTQ+ mental health in the context of minority stressors, in addition to more general social determinants of health.
Have Schemas been Good to Think With?
Authors: Leschziner Vanina , Brett Gordon
Published: July 2021

Schemas are one of the most popular explanatory concepts in cultural sociology, and are increasingly used in sociology more broadly. In this article we ask the question: have schemas been good to think with? We answer this question by analyzing the ontological, epistemic, and methodological bases of schemas, including the conceptualizations, claims, assumptions, and methods that underpin the use of schemas in sociological inquiry. We show that sociologists have developed two distinct, contradictory, and often conflated perspectives on schemas, what we refer to as culturalist and cognitivist perspectives. We suggest that schemas have acquired a polysemic character in sociology, and that they have become a (more narrow and consequently more scientifically legitimate) proxy for Culture, and that these features have (paradoxically) facilitated the popularity of schemas within the discipline. Sociologists have recently begun to make the necessary advancements to turn schemas into a more useful explanatory concept, through both analytical improvements (by distinguishing schemas from both public culture and other forms of nondeclarative personal culture), and methodological innovations (for better deriving schemas from survey data, texts, and experiments). Yet, some challenges remain, and the analytical value of schemas remains promissory. We conclude by offering some guidelines for making more specific and measured claims about schemas in sociological research.
A Change is (not) Gonna Come: A twenty-year overview of Italian grandparents-grandchildren exchanges
Authors: Pasqualini Marta , Di Gessa Giorgio , Tomassini Cecilia
Published: July 2021

Levels of coresidence, residential proximity, face-to-face contacts and intergenerational support exchanges remain overall high and stable across European countries. However, to date, few studies have focused on trends in grandparent-grandchild relations. Therefore, this study aims to investigate whether and to what extent grandparent-grandchild exchanges have changed over time. We used data from the Italian Family and Social Subjects (FSS) Surveys, covering the years 1998-2016, and considered three different currencies of exchanges between grandparents and their grandchildren (coresidence, face-to-face contacts, and grandchild care provision). Our results showed stability over time in coresidence, a small reduction in daily contacts (from 47% in 1998 to 39% in 2016) and an increase in grandchildren care (from 78% in 1998 to 82% in 2016). Also, we found little changes in the associations between such indicators of intergenerational exchanges and the demographic and socio-economic determinants usually used to explain them. Despite changes among Italian grandparents such as increases in their age profile, in education, and in marital disruption, the relations between grandparents and their grandchildren have so far remained stable over time, with generally high levels of intergenerational exchanges.

Introduction: Nutrition plays a vital role in sports. Athletes must understand the importance of diet and ensure that they meet the nutrient requirements to enhance sports performance. The lack of understanding in sports nutrition will lead to poor dietary practices that can cause detrimental effects on athletic achievements. This study aims to evaluate the effects of knowledge, attitude, and practice (KAP) regarding sports nutrition and dietary intake among young university athletes. Methods: Twenty-one local university athletes (23.8±3.4 years) were recruited, and their anthropometric and socio-demographic data were assessed. All participants attended a 1-day sports nutrition class. The KAP-Sports nutrition questionnaire was administered. Three days of dietary intake were also recorded at the same timepoints among the participants. Results: There was a significant increment (p<0.05) in the mean scores for KAP among the participants. Total energy and total carbohydrate intakes per day were significantly increased (p<0.05). However, overall protein and fat intakes did not improve as the readings were higher than the recommended values. Conclusion: In this study, sports nutrition education improved participants’ KAP, but not the actual dietary intake. Changes in habit require more effort, with extra attention on protein and fat intakes.
Występowanie deficytów bliźniaczych w wybranych państwach Unii Europejskiej i w Polsce w latach 2009–2018

Published: July 2021

The aim of the article is to determine the degree, direction and strength of impact of the studied variables, i.e. the state budget balance and the current account balance as part of Poland's balance of payments in the years 2009-2018 against the background of selected European Union (EU) countries. The main research questions focus on determining the type of relationships connecting the studied deficits in the light of previous studies dedicated to the twin deficits hypothesis. The methodology used is based on integrated correlation analysis, linear regression and an analysis of the coefficient of variation. As a result of the study, a strong correlation was found between the cumulative values of the studied deficits, which confirms the existence of the twin deficits hypothesis in Poland in the examined period and means that the budget deficit affects the current account balance. A change in the cumulative balance of the budget by 1% leads to a change in the cumulative balance of the current account of the balance of payments by 0.89%. It can be presumed that the problem of budget deficits and the related debt crisis as well as balance of payments balances under the dichotomy of "surplus north" and "deficit south" in the next decade will be one of the most conflicting and disintegrative for the EU. Thus, the search for a path to budget (internal) balance and balance of payments (external) is one of the key challenges for maintaining cohesion and maintaining sustainable development both in Poland and the entire EU.
Koncepcja wspólnej podstawy biegłości językowej w rozwijaniu umiejętności argumentacyjnych dwujęzycznych uczniów Szkół Europejskich
Authors: Dobkowska Joanna
Published: July 2021

The article presents the possibility of using the concept of a common core of language proficiency in developing the argumentative skills of the bilingual students of European Schools – an institution comprising a network of educational centres operating in the European Union, which provide multilingual and multicultural pre-school, primary and secondary education. In the study, conducted with the desk research method, the author analysed curriculum documents constituting the basis for the work of native and foreign language teachers in European Schools. The research shows that the curricula for different languages provide for similar general competences, but differ in terms of the philosophy of language education and the emphasis placed on particular content and teaching methods. This opens up the possibility of collaboration between teachers, who can increase the effectiveness of their work by building on skills common to all languages.
Korczakowska pedagogia w Domu Sierot na podstawie zapisków Róży Sternkac
Authors: Lasota Wojciech
Published: July 2021

The article is based on an analysis of Róża Sternkac’s notebooks, which are a previously unused archival source from the history of the Orphans’ Home. On that basis, chosen examples of Korczak’s pedagogy being used in reference to various aspects of the functioning of Orphans’ Home have been identified. The examples, however, do not concern Korczak himself, but the notebooks’ author, mentored by Stefania Wilczyńska. The previously mentioned analysis allows us to trace the path of the young educator’s development. Starting with the struggle of the first pedagogical challenges, the path eventually leads to the formation of an attitude of effective action based on self-knowledge, understanding children, and work conditions. Another important factor is in-depth self-reflection, concerning not only one’s actions and emotional states, but also the sphere of values and institutional conditions. The article concludes with a proposal to broaden the understanding of the term “Korczak’s pedagogy” to the area of shaping young educators’ and pedagogues’ abilities to create their own, original pedagogy.

The article investigates the energy efficiency of motor-transmission units when using internal combustion engines with different numbers of cylinders. Transmissions, those in a unit with piston internal combustion engines are loaded with uneven torque, which is the cause of torsional vibrations of their parts. Torsional vibrations create additional dynamic loads on the transmission elements, and also reduce its efficiency. To ensure a high level of energy efficiency of the engine-transmission unit, the elastic-inertial parameters of the transmission must be matched with the amplitude-frequency characteristics of the torque of the installed engine. When replacing a serial internal combustion engines with an engine with output characteristics different from the prototype, it is necessary to assess the vibration resistance of the modernized engine-transmission unit, which was done in this work. As a criterion for vibration resistance of the modernized machine unit, the cyclic elastic efficiency of the transmission was used. This factor takes into account the natural frequency of the transmission input shaft, as well as the amplitude and frequency of vibration of the engine torque. The decisive influence on the vibration characteristics of the engine is exerted by the rotational speed of its crankshaft and the number of cylinders. When conducting a comparative assessment of the energy efficiency level of the modernized engine-transmission unit, it was assumed that before the modernization the transmission was in a unit with a single-cylinder internal combustion engine. As a result of the study, the conditions for ensuring the vibration resistance of engine transmission units have been determined, a method has been developed for comparative analysis of the energy efficiency indicators of engine transmission units with different numbers of internal combustion engine cylinders, and possible ways to increase the energy efficiency of engine units of cars and tractors during modernization with a change in the number of internal combustion engine cylinders are indicated.

The article deals with some criteria that substantiate the design and operational performance of automobiles running on alternative fuels; economic efficiency of operation of such vehicles, their ecological conformity; the level of complexity of the design of converted automobiles; labor intensity of their maintenance, repair, etc. ; traction-speed and other different, in comparison with the basic, properties of automobiles while working on alternative fuel (AF); energy consumption and (or) cost price of AF; efficiency of power plant and (or) car on AF; the degree of commissioning (mass production) and further prospects for the development of the design of such automobiles; state of support developed structures at the national (local) level. An expert assessment of the adopted criteria in the order of their importance is made. Along with the analysis of scores, which are presented in points, it is used the ranking method to study the results of the survey of experts. This allows applying the values of the established optimal criteria to justify the operation of vehicles during their work on the AF. The analysis of the matrix correlation shows that the numerical estimates set by the accepted criteria are characterized by a high degree of correlation, and experts are generally unanimous in assessing their importance. The most important criteria for the operation of automobiles on the AF are economic efficiency, traction and speed and other, different compared to the basic, the properties of automobiles while working on the AF. Other criteria are also quite important, the weights for them are much higher than 7%, and they also should be taken into account while conducting an in-depth analysis and synthesis of indicators of optimal operation of automobiles on the AF. In addition, it is important that the group of criteria that characterize only one type of automobile when working on the AF (for example, the degree of commissioning) experts gave only about 17% of the importance.

The analysis of features of research of efficiency of transport systems at stages of their life cycle is resulted. It is found that the life cycle of the system is reflected in the gradual development of the generalized operation as a process of gradual accumulation of information about the properties of the created transport system, environmental conditions and ways to use it as an active tool in the operation. A formalized scientific approach to assessing the current and future efficiency of transport systems, based on aggregation indicators to assess the effectiveness of facilities in subsystems at different stages of the life cycle, allowing decision-making to see trends in internal development of a complex system as a whole, and integrate knowledge groups of experts in the formation of artificial reference limits of efficiency. It is revealed that in process of accumulation of the information on transport system the estimation of efficiency of operation is specified that leads to fuller substantiation of the accepted decisions, at each stage of a life cycle of system. It is noted that at the stage of external design the choice of rational requirements for the system is based on fairly general efficiency criteria that do not lead to too strong a narrowing of the set of acceptable strategies. Thus, the use of a "strong" principle of optimization and a small number of optimal strategies that lead to the choice is not always justified because in the early stages of the life cycle it is impossible to trace the progress of the operation in all its details. It is suggested that at the stages of external and internal design of the transport system it is advisable to organize a consistent exchange of information between the representatives of these stages of design, which can occur according to a certain scheme. It was found that objects that are on the verge of efficiency are most effective only in a specific group of objects. As it is not possible to set theoretical reference limits of efficiency without the involvement of experts, therefore efforts should be directed to increase the degree of validity and reliability of expert assessments, as a result of which artificial reference limits of efficiency are formed.

The problem of truck cranes is considered, in particular, the issues of ensuring the strength of the supporting structure of the chassis in different modes of operation, taking into account the peculiarities of the technological cycle. In truck cranes, the load loads are unevenly distributed. They depend not only on the weight of the crane and the load, but also on the position of the rotating part of the crane relative to the non-rotating, as well as on the departure of the boom. Loads on the support surface are transmitted through the outriggers. During the operation of the truck crane, the load on each remote support does not remain constant. Estimated loads, namely loads from the crane installation and cargo, will take into account different values of cargo weight, departure and crane height. Their size and location are determined according to the crane capacity diagram. Based on the analysis of scientific works on the impact of subsidence of outriggers in the ground during the operation of truck cranes, it can be argued that this factor is quite significant and must be taken into account when calculating the strength of the truck crane. Moreover, the load on each of the supports is different and changes with each operating cycle, when changing the trajectory and working with different loads. Based on the comparative analysis of existing analogues, the limits of variation of the main technical parameters for the design of a family of special chassis for truck cranes are determined. The dangerous modes of operation of the truck crane, the influence of both the main parameters and external factors on the magnitude and nature of the load were calculated. The results of the calculations are plots of complete deformation, equivalent stresses and margin of safety. In maximum load mode, the main load falls on the rear of the frame and the rear outriggers. Maximum and minimum altitude modes are not particularly dangerous. In addition, the greater the height, the less dangerous is the high flight of the arrow. Large capacity is possible only on small flights and heights.
Investigation of the interaction of car wheels with the stand rollers during braking

Published: July 2021

The article discusses the issues of modeling conditions for obtaining diagnostic information about complex objects. As an example, the study of the braking qualities of four-wheel drive cars on an inertial roller stand is considered. Diagnosing the technical condition of cars from the point of view of traffic safety is one of the most important problems. This is especially important for systems whose technical condition affects traffic safety: especially braking systems. Foreign and domestic experience testifies to the effectiveness of instrumental control. The diagnostic equipment includes roller stands, on which you can check the braking properties of cars. As shown by many studies, in particular, carried out at the Department of Technical Operation and Service of Automobiles, KhNADU (HADI), inertial stands provide more reliable information about the technical condition of the car. Such stands allow you to reproduce the real speed and thermal modes of the brakes (especially those equipped with ABS). To improve the accuracy of diagnosing a car on a roller stand, it is necessary to have an idea of the nature of the interaction of the car wheels with the rollers. The studies of wheel rolling on the stand rollers have been carried out by many authors since the 80s of the last century. However, all these studies were carried out on uniaxial stands and for mono-drive vehicles. Nowadays, a large number of passenger cars have four-wheel drive. Rolling of the wheels of such cars on rollers and their interaction has practically not been studied. Therefore, a return to the study of this issue is relevant. A power model of the system of interaction between the car and the stand has been developed, taking into account the design features of the stand and the design features of the car's suspension. The power model of the system under consideration contains the equilibrium equations of the body and two bridges and the equations of motion of the rollers and wheels of the car. Based on the results of the analysis of the acting forces in the "car-stand" system, the braking moments on the wheels M and the coefficients of the use of the load q during the braking tests of a 4x4 vehicle were determined. The obtained research results allowed to improve the theory of interaction of a car wheel with the rollers of an inertial diagnostic stand.

The article discusses a methodology for assessing the functional suitability of brake systems to change the braking path of passenger cars, taking into account various operating conditions. The goal is achieved by using the method of mathematical modeling of the emergency braking process, taking into account the possible operating conditions of cars performing emergency braking at certain initial speeds, in particular, exceeding 100 km / h. Based on the analysis of scientific sources, it has been established that the determination of the braking efficiency of a vehicle classically occurs on the verge of blocking all wheels with known methods of distributing braking forces between the axles of the vehicle. In this case, the standards set the maximum value of the minimum deceleration and braking distance. In addition, the jump in the maximum possible value of the braking force between the wheels of each axle makes it possible to compare it with the requirements of DSTU 3649: 2010, and the assessment of the magnitude of this jump for each braking of the car is to establish its functional suitability. As a result, according to the magnitude of the jump in the maximum possible value of the braking distance, the change in the maximum allowable braking force of the car sets, and according to the magnitude of its jump, it is possible to assess the functional suitability of its braking system. As a result, the use of expert information on the value of jumps in the maximum possible value of the braking force of a car, affecting the braking torques and braking coefficient, can reduce the amount of experimental research and significantly reduce the time to reach an objective decision on the functional suitability of the brake systems of operated cars. The paper presents the results of theoretical studies of passenger cars Chevrolet Aveo, Lada Priora and Forza with different loads, performing emergency braking at an initial speed of 40-150 km / h on a road with dry asphalt concrete. The boundaries of the coefficient of the relative change in the braking distance of the tested passenger car, at which it is possible to make a conclusion about the functional suitability of its braking system, have been established.

The article provides a comparative analysis of existing software products and libraries that allow the design of multi-agent systems for diagnostics and maintenance systems for modern cars. The authors substantiate two main shortcomings inherent in all products - analogues: the need for high qualification of the user as a software code developer, and low performance of intelligent methods in the structure of agents, which worsens their performance. Both manufacturers and car owners are objectively interested in the widespread use of telematics systems for monitoring the technical condition of cars. Predictive diagnostics gives them access to a huge amount of information about all the nuances of car operation, wherever they are, during the entire service life. The application of this approach using a multi-agent system (MAS) will allow taking the next step in this direction. Information from the connected vehicles goes to the main server. Systematization and analysis of data make it possible to establish the causes of malfunctions, identify patterns of their occurrence and make further predictions. Purpose of the work: to perform a comparative analysis of existing software products and libraries that allow the design of multi-agent systems. The topic of the work is disclosed on the example of the analysis of software tools for the development and design of MAS at the present stage. There are a number of systems and libraries on the market designed for the development of multi-agent systems. These Case - systems are suitable for the development of multi-agent systems of any direction, that is, they are universal from this point of view. Therefore, for us it is a universal application tool for the automotive industry. Ultimately, the work performed a comparative analysis of existing software products and libraries that allow the design of multi-agent systems. The analysis revealed two main drawbacks inherent in all products - analogs: the need for high user qualifications as a developer of software code, and low indicators of the possibilities of introducing intelligent methods into the structure of agents, worsens the indicators of their work.

The article is devoted to the study of the influence of mobile network settings on the energy consumption of electronic car control units. Signal quality and mobile network coverage are also important for both users and automotive devices that use real-time information from the network using cloud technologies to transmit, process and store data. For the quality of service measurements, Communications Regulatory Authority uses just HTTP data transmission (receipt) speed rate values in the operators’ UMTS (3G) networks (as CRA stated in annual report). But speed is not everything as many consumers in the industry are experiencing recently. In addition, improvements now also revolve about reducing the signaling load incurred when a radio bearer is established, modified or released. Another area for improvements is the signaling overhead on the air interface when little data is transferred as it consumes resources and causes battery drain from the mobile phone's point of view. The authors focused on the UMTS (the Universal Mobile Telecommunications System) 3G network, which is among the most popular 3G mobile communication technologies. We explore the RRC state machine of large cellular networks which operate in Lithuania. Note that in UMTS network, the centralized core network (CN) is responsible for ensuring switching and routing for the end users traffic. All Network management functions and required databases are also implemented in core network. The core network domain is further divided into sub categories: serving network domain, home network domain and the transit network domain. It consists of two kinds of General Packet Radio Service (GPRS) Support Nodes (GSNs), in 3GPP named as Gateway GSN (GGSN) and Serving GSN (SGSN) (Figure 1). SGSN is the central node of the packet switched (PS) domain. It provides for routing functionality and interacts with databases (like Home Location Register (HLR)) and manages many Radio Network Controllers (RNCs). So the authors were researching the RRC machines of Lithuanian cellular operators’ networks. The purpose of those experiments was to identify which network could provide a best user internet browsing experience, best user equipment battery consumption feature and best radio network resource utilization scheme. We can state, that comparing all these partitions, Operator2 has the optimal configuration for user experience, UE device battery consumption and network resource utilization of RRC state machine point of view.
