Published: May 2022

Increased temperature resulting from friction between brake pads and rotors results in formation of friction layers on the friction surfaces and could lead to the bulk material degradation impacting the braking performance. The most often discussed phenomenon is the thermal fade, but there are additional phenomena like thermal shock, crack formations, and increased residual stresses in brake rotors which occur due to local heating. Formation of friction layers is also strongly influenced by temperature on the friction surface, as it defines thermodynamics and kinetics of processes occurring during friction. Gray cast iron is a metal matrix composite comprising of ferrite, pearlite, graphite, and additional inclusions. Morphology, quality, and quantity of these phases can change as temperature varies during and after friction process. Thermal diffusivity characterizes how quickly a material could dissipate heat through it. Grey cast irons exhibit a reasonably high thermal diffusivity and an excellent capacity to dissipate heat. But this characteristic varies in dependence on composition and microstructure of cast irons. The volume content and morphology of graphite flakes found in gray cast irons have the most relevant impact on their thermal diffusivity values. The current study compares the graphite flake morphology of three commercially available gray cast iron rotors, named A, B, and C respectively, manufactured according to the ASTM A48 standard. These rotors are subjected to a complete currently available standardized SAE J2522 friction test on a bench top tester using scaled-down approach, and a commercially available non asbestos organic (NAO) brake pad. Complete material characterization of the friction material using laser flash apparatus (NETZSCH LFA 467), polarized light microscopy (Nikon Microphot FX), scanning electron microscopy (FEI Quanta FEG 450), energy dispersive X-Ray microanalysis (Oxford detector, Inca Systems), topography (NPFLEX 3D Optical Microscopy), and density (analytical balance and Archimedes principle). The polarized light microscopy results of the three commercially available brake rotors reveal the presence of flake-like graphite with average flake sizes as 55 µm, 33 µm, and 60 µm and area fraction as 28%, 26%, and 30%, respectively. Thermal diffusivity values of the studied rotors when measured in temperature range between 25 oC and 500 oC show a decrease by 52.4%, 53.6%, and 54.8% respectively. Commercial brake rotor C exhibited the presence of increased content of oxides in the friction layer formed during elevated temperatures, which helped in the observed improved friction performance.

Manufacturing train fleets for countries that have extreme weather/climatic condition is always a specific challenge, moreover when the concerned country has a huge difference itself inside. Even under such specific constraints and conditions, the train and in particular the brake system must remain reliable and available. Some simple examples: How can we (car builders) make sure that the train will still brake if ice or snow is built up on brake acting component? Or if the exhaust of brake pipe (emergency brake) is clogged by ice?

 If a train has failure between 2 far station (>250 km), it shall be able to run to reach the next (far) station. The presentation aims to: Present the fleet running locations, numbers and route distances, Present the requirements depending on the location (south vs north vs center Sweden), weather conditions (snowy, extremely cold)…, Overview of the specific solutions and features present to fit to the constrains: redundant AGTU for specific region, specific retardation test from brake and signaling system. We will present the real effect by examples of the snowy, extremely cold, humid climatic conditions: Pictures of a train with bogie completely hidden behind snow, Video of iced caliper moving by braking the ice (test bench) This will be just quick go through, since we plan a dedicated presentation for the winterization separately for the session in 2020. We will also present the specific feature of the brake and signaling system for Sweden: Retardation test. What is the aim? What is the historical development of it? How does it work? What are the attention compared to a performance test?

 What are the special solutions used for adapting the retardation test from UIC to a direct brake system?

Condition Monitoring (CM) offers opportunities for improvement of safety, availability while typically also reducing maintenance cost. For some asset classes however, large up-front investments are required. Most notably, for the wagon subsystem of the freight rail system, a close monitoring of brake performance using on-board sensors for monitoring of the brake hardware using e.g. force sensor appears expensive and economically not viable. The approach outlined in this paper picks up on the approach of the author's contribution to Eurobrake 2019, where a big data approach merely based on accelerometer measurements was proposed. This yields the advantage of reducing hardware cost, both initial investment as well as maintenance cost, since accelerometers are everday electronic components which typically show a large lifespan with little degradation. This reduction in hardware cost needs to be compensated by more elaborate computational approaches, since it is based on the contribution of each individual wagon's brake to the braking performance of the entire train consist. By help of randomised mixture of the wagons during train formation, such an approach may be used to detect degradations of individual wagon brakes. Since such an approach relies on multiple train operations, it is obviously not suited for the replacement of the classical operator based pre-departure check. It may however increase safety and availability on an individual wagon basis due to the ability to observe degradation prior to becoming a functional limitation to be handled during a pre-departure check. Furthermore, it is well suited to supplement novel forms of brake assessments, such as automated brake tests or automated visual inspections and thus provide a higher level of safety and availability at reduced overall cost. The paper features a brief recap of the proposed method, integrated into the Wagon4.0 concept, which is one potential hardware and software basis as well as a review of big data approaches. The development of a simulation environment suitable for the generation of big data sets based on a headless MATLAB/Simulink setup on a cluster architecture is described. The model features an approximation of the pneumatic behaviour of the brake pipe, a simplified wheel-rail contact model, varying brake block friction as well as a parameter based model of a distributor valve for each simulated wagon. Thanks to the hardware and software setup, the simulation environment is able to generate braking data in the range of multiple Terabytes, which can then be analysed using big data approaches. Wagon parameters are sourced from a partly randomised digital wagon pool, which can be sent on virtual mission while observing their braking behaviour. The paper finishes with a preview of the intended analysis, which is currently being implemented on the FH Aachen cluster.

Published: May 2022

Geographical Weighted Regression (GWR) is used to improve decisionmaking in spatial analysis. Instead of the Ordinary Least Square (OLS) regression method that gives a single estimated parameter, the GWR method can provide unique estimated parameters in each location. This study aims to conduct a formal statistical inferential framework on the violent crime rate using the GWR. This analysis discovers the geographical distribution and pattern of criminal cases in Peninsular Malaysia using the average crime rates from 2000-2009, with focus on on violent crime. The comparison of OLS regression, known as Multiple Linear Regression (MLR) with the GWR method, was done to show that GWR was the best model. The GWR output suggests that about 30% of districts showed a significant correlation between violent crime and non-citizen rates. These findings contradict the result from the MLR model, also known global model. The global model could not create any other connection to explain the lack of parameter-location correspondence. Finally, the importance of local relationships in crime studies is necessary to understand the actual crime rate.

The significance of this topic is that public servants perform public administration tasks as their primary occupation and as such represent a key and irreplaceable subject of public administration. Through their position and daily contacts with citizens, they are the focus of attention and criticism, whether in a positive or negative context. Their profession is everywhere in the world, and even in our region, of traditionally respectable character with many challenges and opportunities, viewed since time immemorial in Serbian history, of a very influential official status. This is why the code of conduct is of paramount importance for local government units. Adoption of a code of conduct is of the utmost importance for the development of good practice and the application of standards of conduct for local officials. Adopting European standards of professional and ethical behavior not only reduces the application of the normative method, but also the application of codes of conduct. Through the analysis of standards of ethical conduct, professionalism, responsibility, honor, quality of service, a comprehensive understanding of the ethics of local employees will be provided.

Functionality of higher education institutions in the conditions of modern society sets out requirements for reflection on the quality of management processes, which take place within their framework. The interest in establishing an analogous application of the basic principles of corporate governance to higher education institutions has been initiated in the paper. Considering the significant contribution that corporate governance has made, successfully responding to crises in which particularly large holding systems have been in business, it is reasonable to accept the thesis about the possibility of extending the understanding of corporate governance to the management processes, structures and forms of higher education institutions. This is all the more so, given that understanding of knowledge as a particular commodity is eligible to appear on the market. Modern higher education checks its own quality in the conditions of the market of knowledge, capital and labor, which is why it is necessary to search for principles that will ensure higher quality competitiveness of higher education institutions. The research conducted is the beginning of work to justify the application of corporate governance principles in this area.

Published: May 2022

Background. The period of intensive growth in children is associated with active changes in the bone tissue architecture. A high level of bone mass accumulations was observed. Whether such processes are adequate depends on numerous factors, however, all of them are based on a genetic component. Gene expression affects all the processes in the body, including bone tissue. The BSML and Fokl polymorphisms of the VDR gene responsible for the activity of cell receptors for vitamin D is studied in association with bone pathology, autoimmune diseases, diseases of the central nervous, cardiovascular and other systems. Purpose – of the research is aimed at determining densitometric features of the structural and functional condition of bone tissue in children during the growth spurt, taking into account polymorphisms of BSML, FOKL gene VDR and vitamin D levels. Materials and Methods. The examination covered 205 healthy children aged 9–17, who were divided into groups depending on the presence or absence of growth spurt (GS) and its intensity. The examination presupposed analysis of the medical history, assessment of physical and sexual development, ultrasound (QUS) and X-ray (DXA) densitometry, determination of 25-(OH)-D levels, molecular diagnostics- definition of polymorphisms of BSML, FOKL gene VDR. Results. Ultrasound densitometry showed a decrease in bone mineral density (BMD) in 24 children of Group I (48.0%), Z-score: – 1.8 ± 0,56; 28 children in Group II (60.87%), Z-score: – 1.96 ± 0,27 and 43 children of Group III (39.45%), Z-score: – 1.68 ± 0,72. DXA was used for 32 children, 18 of them (56.25%) were diagnosed with a decreased BMD. Children of Group I with a reduced BMD had an average level of vitamin 25-(OH)-D at the value of 39.04 ± 11.84 nmol/l, while in children with a normal BMD it averaged – 42.43 ± 6.3 nmol/l. In children of group II BMD in which it was reduced, the average level of 25-(OH)-D was 45.68 ± 5.48 nmol/l, with normal BMD – 45.47 ± 4.69 nmol/l. Children of Group III with a reduced BMD had an average 25-(OH)-D level of 36.73 ± 8.94 nmol/l, those with a normal BMD showed the 25-(OH)-D level of 42.91 ± 9.1 nmol/l. A molecular study found that 48.76% of children did not have any mutations in the VDR gene BSML polymorphism, 41.32% of children showed a heterozygous mutation, and 9.92% of children revealed a homozygous mutation. 27.81% of children had no mutation of Fokl polymorphism in the VDR gene, 61.95% showed a heterozygous mutation and a homozygous mutation was detected in 10.24% of children. Conclusions. Decreased bone mineral density in children during growth spurt is due to insufficiency or deficiency of vitamin D and is determined genetically. However, the most significant factor in the BMD reduction is the retardation of bone mass accumulation processes against the background of an intensive linear growth of the skeleton.

Persuasion is the process of communication in which a person wants to create an influence to induce certain behaviour sends a persuasive message to the other individual with the aim of generating an impact on the recipient's attitude. The power of decision making, however, is at the disposal of the recipient. Various technologies are used by the donation based crowd funding platforms to persuade the website visitors to make donations for certain causes. The main objective of the study was to focus on the specific factors that are used by the donation based crowd funding platforms to persuade the prospective donors to make donations to specific campaigns. Exploration methods were used to obtain the necessary data through online questionnaires. The questionnaire mainly included close ended questions where most of the questions were designed for the people who have donated using crowd funding platforms to react on a Likert scale of 5 (Strongly Agree to Strongly Disagree). Total sample size was 230. Simple Random Sampling method was used to collect the data. The researcher has explained a model where building a new concept in the set of factors that are specifically applicable for the donors who contribute for donation based crowd funding campaigns. The model shows that using technology in persuasion and having a higher social networking presence can affect the donation intention of the website visitors to a considerable extent. The model also shows that various privacy issues, trust and overall website quality also have a major impact on the donation intention of the donors. In the end, the study also shows that the donation intention of the donors is highly positively correlated with the donation behaviour.

The practice of surrogate mother is widely applied abroad, but in Indonesia there is a lot of opposition from the community. In Indonesia, this practice has not received a clear legal force. This is related to the clarity of the legal status of the child being born as well as the legal status of the rent of the womb of another person who has not been regulated. The purpose of this study is to determine the legal position of surrogate mother and its implementation based on ethics and religion in Indonesia. This study uses a normative juridical approach. The results of this study indicate that surogate mother in Indonesia is null and void because it is contrary to Article 1320 of the criminal code; in addition, from the side of criminal law is also contrary to Article 284 of the Criminal Code. Even surrogate mother declared not in accordance with the norms of decency in Indonesia.

Published: May 2022

The main statements of the recommendations of the American College of Rheumatology and the Vasculitis Foundation on the treatment of patients with systemic vasculitis of large vessels, published in August 2021, are discussed. As a result of a detailed review of current data, a group of experts proposed 22 recommendations and 2 ungraded position statements for giant cell arteritis (GCA), as well as 20 recommendations and 1 ungraded position statement for Takayasu arteritis (AT), on the basis of which algorithms for the treatment of patients with these diseases are presented. An expansion of the value of genetically engineered biological therapy, primarily tocilizumab in GCA and tumour necrosis factor alpha inhibitors in AT, has been recorded. The new recommendations should not be considered as final standards, but are intended to become the basis for choosing a personalized treatment strategy for patients with large vessels vasculitis and serve as a starting point for further research.

Published: May 2022

Objective. Assessment of clinical manifestations and ultrasonographic signs of enthesitis (En) in patients with psoriasis (PsO) and psoriatic arthritis (PsA).

Subjects and methods. The study is based on the analysis of survey data from 106 patients with PsO for the period 2018–2021, which were firstly sent by dermatologists for a consultation with a rheumatologist due to musculoskeletal pain. The duration of the period of musculoskeletal pain in the observed patients did not exceed 12 months. In addition to general clinical and laboratory examination, all patients underwent ultrasonography of painful and/or swollen joints, tendons and ligaments using a linear sensor (frequency – 12–18 MHz) of MyLab 50 (Esaote, Italy) apparatus and supplemented by Doppler energy study with a pulse frequency of 6.6 MHz. The OMERACT definitions were used to identify En, synovitis and tenosynovitis.

Results and discussion. The diagnosis of PsA was established in 73.6%, osteoarthritis – in 13.2%, gout – in 8.4%, fibromyalgia – in 17.9%. Ultrasonographic signs of En were found in 67.9% of patients: signs of an active inflammatory process in enthesises (decreased echogenicity, thickening and appearance of Doppler signals) were observed in 48.7%, signs of structural damage to enthesial zones (calcifications, enthesophytes and bone erosions) in 25,6% of patients. Isolated En was found in 24.4% of patients, a combination of En and synovitis – in 32.1% of patients, a combination of En and tenosynovitis – in 20.5% of patients. The correlation between the inflammatory domain values of the ultrasoundographic enthesial index MASEI (Madrid Sonographic Enthesitis Index) and the clinical enthesial index LEI (Leeds Enthesitis Index) was 0.71 [0.58; 0.77]. There were less pronounced clinical indicators of enthesial inflammation (lower LEI index values), functional disorders of the joints (lower values of the HAQ-DI index) and laboratory signs of systemic inflammation (lower CRP values) in patients with isolated En in comparison with combination of En and synovitis. Ultrasonographic signs of structural damage of enthesises were observed in 15.4% of patients without clinical and ultrasonographic signs of active En, which may indicate the possibility of a subclinical course of enthesial inflammation in patients with PsO.

Conclusion. It was demonstrated that ultrasonography has diagnostic capabilities to identify the site of the inflammatory process in patients with PsA and differentiate patients with isolated En and a combination of En and synovitis in order to select a method of differentiated anti-inflammatory therapy.

Uma questão importante a ser levada em consideração é a insatisfação dos alunos com as aulas tradicionais. As metodologias ativas estão presentes nesse processo de mudança e com a pandemia do covid-19 elas foram mais importantes. O uso de tecnologias para desenvolvimento de aulas remotas exigiu dos professores e alunos uma reestruturação das ferramentas a serem utilizadas nas aulas. Uma dessas metodologias é a aula invertida. Ela foi muito utilizada durante esses últimos anos. Esse trabalho tem por finalidade apresentar um estudo de caso desenvolvido na disciplina de Organização Industrial, em duas faculdades de tecnologia, no curso de Automação Industrial. Foram utilizados artigos a serem discutidos em sala através de resumos e questões a serem elaboradas pelos alunos. Ao final das atividades foram desenvolvidas pesquisa de satisfação com os alunos. Ao longo do trabalho serão apresentadas a metodologia e os resultados obtidos

Objetivo: Discutir a importância do cuidado farmacêutico a pacientes idosos submetidos à farmacoterapia da dor cônica e contextualizar as ações que podem ser desenvolvidas para este público, de acordo com as atribuições clínicas do farmacêutico previstas em legislação. Métodos: Estudo de revisão integrativa, de caráter qualitativo sobre as ações do farmacêutico no cuidado ao paciente idoso com dor crônica, aborda uma discussão pautada na Resolução nº 585 de 29 de agosto de 2013. Foram selecionados artigos publicados entre os anos de 2013 e 2020, nas bases de dados BVS, CAPES, Google Acadêmico, PubMed e SciELO. Os descritores utilizados foram “cuidado farmacêutico”, “idoso”, “geriatria”, “dor crônica” e seus correspondentes em inglês, associados ao termo booleano AND. Resultados: Foram inclusos quatro estudos na revisão, todos nacionais. Três realizados com pacientes hospitalizados e um estudo com pacientes do Programa de Saúde da Família. A maioria dos estudos formam compostos por pacientes do sexo feminino. A idade de todos os participantes variou entre 60 a 90 anos e as classes medicamentosas mais relatadas foram os AINEs e os analgésicos opioides. Conclusão: Verificou-se uma expressiva escassez de materiais publicados sobre a temática dos cuidados farmacêuticos a pacientes idosos usuários de medicamentos para dor crônica. Os pontos mais relevantes na construção dessa revisão reforçam a importância da intervenção e acompanhamento farmacoterapêutico, pautadas nas suas atribuições clínicas. Acredita-se que os resultados discutidos podem servir como base para discussão em outras instâncias e sensibilizar gestores e profissionais de saúde a incorporarem práticas de cuidado farmacêutico em suas rotinas.

Published: May 2022

This paper considers systems of linear Fredholm-Volterra integral equations using a modified homotopy analysis method (MHAM) and the Gauss-Legendre quadrature formula (GLQF) to find approximate solutions. Standard homotopy analysis method (HAM), MHAM, and optimal homotopy asymptotic method (OHAM) are compared for the same number of iterations. It is noted from the chosen examples that MHAM with GLQF is comparable with standard HAM and OHAM. In all cases, MHAM with GLQF approaches exact solutions, where residual rapidly converges to zero when the number of iterations and quadrature nodes increases. The HAM developed in this paper is better than the HAM developed by Shidfar & Molabahrami in "Solving a system of integral equations by an analytic method".

Published: May 2022

The primary objective of this paper is to develop the Refinement of Successive Over-Relaxation (RSOR) method based on a three-point linear rational finite difference-quadrature discretization scheme for the numerical solution of second-order linear Fredholm integro-differential equation (FIDE). Besides, to illuminate the superior performance of the proposed method, some numerical examples are presented and solved by implementing three approaches which are the Gauss-Seidel (GS), the Successive Over-Relaxation (SOR) and the RSOR methods. Lastly, through the comparison of the results, it is verified that the RSOR method is more effective than the other two methods, especially when considering the aspects of the number of iterations and running time.

Published: May 2022

The use of Lightweight concretes has gained acceptance and popularity worldwide in the recent years in the construction and development of both the infrastructure and residential buildings. Light weight aggregate concrete has become more popular in recent advancements owing to the tremendous advantages it offers over the conventional concrete but at the same time light in weight and strong enough to be used for structural purposes. Replacement of natural aggregate with concrete such as light weight concrete by using sintered fly ash aggregate (natural aggregate), The main disadvantage of conventional concrete it is high self -weight. This heavy self-weight will make it to some extent an uneconomical structural material. Light weight concrete having low density facilitates reduction of dead load and to increase thermal insulation.
