STATIČKA MKE ANALIZA I ANALIZA OSCILOVANJA STUBA VETROGENERATORA
Authors: Goločorbin Stanko 
Published: January 2021

Stubovi vetrogeneratora su jedni od najkompleksnije opterećenih stubova (tornjeva) koji postoje u građevini. Uzimajući u obzir da promenljiva priroda brzine vetra intenzivno menja opterećenje na stub u vidu ekscentričnog momenta. Cilj ovog istraživanja je dobijanje rezultata statičke MKE analize u vidu napona prema kojoj možemo, shodno najvećim naponima, promeniti dizajn samog modela stuba vetrogeneratora. Takođe istraživanjem oscilacija stuba i pronalaženjem sopstvenih kružnih frekvencija oscilovanja dobijamo zanje o brzini obrtaja rotora koju treba da ograničimo da stub ne bi mogao da uđe u rezonantni režim. U radu je prikazana primena metode konačnih elemenata (MKE) pri pronalaženju napona stuba pomoću ABAQUS – softvera i primena teorije oscilacija pri pronalaženju sopstvenih kružnih frekvencija i maksimalnih amplituda pomoću Mathematica – softvera, 3D model korišten za MKE analizu je izrađen u Solidworks – softveru.

RESUMOO mundo em permanente transformação, veloz, universal e em rede, e o advento da Internet propiciaram o surgimento de uma sociedade em rede marcada por mudanças acentuadas na economia, impulsionando o nascimento de novos paradigmas, modelos, processos de comunicação educacional e novos cenários de aprendizagem. É, precisamente, um desses novos cenários que pretendemos analisar, descrevendo o seu impacto no autoconceito académico de vinte estudantes reclusos da Universidade Aberta, Portugal, a partir da análise qualitativa das suas perceções e narrativas e tendo como referencial o Modelo Pedagógico desenvolvido por Moreira (2017) para o desenho de e-atividades de aprendizagem centradas na “desconstrução” de imagens em movimento. Os resultados mostram que o design do ambiente, ancorado neste modelo e na utilização de tecnologias audiovisuais, pode ter efeitos muito positivos no autoconceito académico dos estudantes do ensino superior, a nível das diferentes dimensões consideradas: Motivação, Orientação para a Tarefa, Confiança nas suas Capacidades e Relação com os Colegas. São discutidas as implicações dos resultados encontrados, tanto do ponto de vista de intervenção prática, quanto em termos de investigações futuras.Palavras-chave: Pedagogia. Ambiente Educativo. Cinema. Educação para Todos. Justiça Social. ABSTRACTBoth the world in permanent change, fast, universal and networked and the Internet have propitiated the emergence of a networked society marked by changes in the economy, setting the birth of new paradigms, models, processes of educational communication and new pedagogical scenarios. It is precisely one of these new pedagogical scenarios, that we intend to analyze, describing its impact on the academic self-concept of twenty prisoners/students from the Open University, Portugal, based on the qualitative analysis of their own perceptions and narratives having as reference the Pedagogical Model developed by Moreira (2017). The results show that the design of the environment, anchored in this model and the use of audiovisual technologies can have very positive effects on the academic self-concept of higher education students in the various dimensions taken into consideration: Motivation, Orientation for the task, Trust in their own capacities and Relationship with colleagues. The implications of the results are discussed not only from a practical intervention point of view but also in terms of future research.Keywords: Pedagogy. Educational Environment. Cinema.

Authors: Klejnowski-Różycki Dariusz 
Published: January 2021

Joannes Molanus, teolog, rektor Uniwersytetu w Louvain napisał obszerny traktat, który miał być pomocą dla biskupów i księży, w szczegółowym zastosowaniu ogólnego dekretu soborowego o obrazach. Molanus odrzucił te sposoby obrazowania, które nie są oparte na Biblii, a na apokryfach. Zerwał także z niektórymi przedstawieniami alegorycznymi czy wschodnimi. Stworzył teologiczne podstawy pod katolicką sztukę sakralną, która jest obecna w kościołach do dziś. Artykuł przedstawia analizę dekretu Soboru Trydenckiego o obrazach (1), życie i twórczość Molanusa (2), kontekst czasów Reformacji, w których żył Molanus, zwłaszcza w aspekcie obrazoburstwa (3), następnie zostaje omówiony traktat o obrazach Molanusa (4), istotne kategorie podziału teologicznego, które przypisuje sakralnym dziełom sztuki (5), a na koniec zostają przytoczone niektóre przykłady ilustrujące myśl Molanusa (6). W Podsumowaniu (7) zostanie dokonana ocena wpływu traktatu Molanusa na sztukę sakralną katolickiej Europy.

Objetivo: Relatar um caso de catarata congênita lamelar não associada a síndromes sistêmicas ou malformações congênitas e apresentar a conduta adotada. Detalhamento do Caso: Trata-se de um paciente de cinco anos idade, masculino, sem comorbidades e sem alterações no Teste do Olhinho, referenciado para acompanhamento no Centro Oftalmológico de Minas Gerais em 2017, com queixa de fotofobia intensa. Ao exame foi evidenciado redução discreta da acuidade visual, opacidades cristalinas lamelares em anel em ambos os olhos com eixo visual livre, ausência de alterações de motilidade ocular e níveis pressóricas normais. Considerações Finais: A detecção precoce de alterações oftalmológicas é de suma importância na minimização do impacto das doenças oculares no desenvolvimento psicomotor e cognitivo das crianças. Apesar da importância do teste do olhinho, as cataratas lamelares podem apresentar reflexo vermelho normal ou próximo do normal, deixando de ser diagnosticadas. Neste contexto, mesmo na ausência de dificuldades visuais ou doenças sindrômicas, uma visita anual ao oftalmologista é essencial durante os primeiros anos de vida para diagnosticar casos limítrofes.
Relationship of breathing pattern with vascular tone and arterial stiffness in young healthy individuals
Authors: Sharma Mitali , Bagali Shrilaxmi , Patil Satish G. 
Published: January 2021

Objectives:
A dynamic interaction exists between respiration, cardiovascular system, and autonomic nervous regulatory mechanisms as demonstrated by respiratory sinus arrhythmia. The vascular tone might also demonstrate a similar variability during inspiration and expiration. The breathing patterns by influencing the sympathetic outflow may have an impact on the vascular tone and hence cardiovascular system at large. The present study was undertaken to assess the quiet breathing pattern and its relation with vascular tone, hemodynamics, and arterial stiffness in normal young healthy individuals.

Materials and Methods:
The study involved 46 young healthy adults (both males and females) aged 19–25 years. Breathing parameters included were respiratory rate (RR), inspiration time (IT), expiration time (ET), and inspiration-expiration ratio (I/E ratio). Vascular parameters included were reflection index (reflects vascular tone) and stiffness index (reflects arterial stiffness). Blood pressure (BP in mmHg) and heart rate (bpm) were measured.

Results:
IT and ET were almost equal with no significant difference. ET was weekly correlated with diastolic BP (r = −0.410; P = 0.058) in females but not in males. Breathing pattern was not significantly associated with vascular tone and arterial stiffness.

Conclusion:
IT, ET, I/E ratio, and RR were not significantly correlated with vascular tone and arterial stiffness suggesting that breathing does not influence the arterial health and function in young healthy individuals. There was a weak negative correlation between ET and diastolic BP in females but not in males, implicating the existence of fundamental differences in basic BP regulation between the sexes.

Anterior tooth fractures are more commonly found in younger patients than in adults. Kids in school accidentally fall and break their anterior tooth. It not only has an impact on aesthetics but physiological disturbances due to their friends. The aim of this study is to assess the gender difference in patients who underwent root canal treatment in anterior teeth after trauma. The data was collected from the dental information archiving software of saveetha dental college, from June 2019 to March 2020. The parameters collected were age, gender, a tooth which had undergone trauma. The data was collected and tabulated in the excel sheet and was transferred to the SPSS software by IBM for statistical analysis like chi-square test between trauma teeth and age and gender and traumatized tooth. This study reveals that males had a higher incidence of fracture than females and they belonged to the age group of 2-4 years with a P-value of 0.213 >0.05 (statistically insignificant). This study concludes that male children are more prone for anterior tooth fracture than the female children, and they must be educated on the importance of teeth and safety during sporting or any other physical activities.
Experimental studies of heat treatment influence on the welded connections properties in working mechanisms of road building
Authors: Scherbakov A. Р. 
Published: January 2021

Introduction. The experimental studies of the heat treatment effect on the properties of welded joints in working mechanisms of road-building machines are carried out in the work. Studying the structures of the metal itself, as well as welded joints and considering their heterogeneity, the author analyzes the strength characteristics of these objects.Materials and methods. By means of metallographic analysis, as well as using boron-containing steel 30MnB5, which is used for the manufacture of structures for construction machines, as a research material, the author examined its microstructure, which took place in certain zones of welded joints. In particular, welded jointss, fusion zones with an overheating area, a complete recrystallization area and the base metal were studied. We also studied the features of cold plastic deformation of the specified steel sample.Results. It was determined that the mechanical inhomogeneity of the steel at these joints is the cause of the structural inhomogeneity of the welded joints. As a result of this process, some dangerous zones of acting voltages concentration are formed. These conclusions predetermine the need to identify some certain zones that concentrate stresses in themselves, while it is mandatory to strengthen the metal in such zones to standard indicators. An increase in the strength properties of the steel under study is possible by applying cold plastic deformation and subsequent thermal cycling (STC). This is achieved by obtaining a fine-grained metal structure with higher strength. The author defines the welded joints and the zone of its fusion with the base metal and the overheating area as the most dangerous areas subject to loading. To control this process, it is recommended to use the passive fluxgate method in the work, while the fusion zone with the overheating section should be inspected first, and then the weld.Discussion and conclusion. The author comes to the conclusion that the experimental studies carried out can contribute to an increase in the efficiency of the process of reducing the stress concentration (SC) in the elements of construction machines made of steel and subjected to intensive operation by reducing the structural and mechanical inhomogeneity of welded joints.

Published: January 2021

Introduction. Conducting an experiment when conducting research on electroplating coatings requires a lot of time and energy. To reduce the number of experiments performed, it is necessary to conduct mathematical modeling of the experiment to reduce the number of experiments performed and reduce it to a specific algorithm to obtain reliable and accurate data. The obtained reliable data will allow to get good results in studies of obtaining chrome coatings, with maximum performance, including current output.Materials and methods. To conduct the research, the necessary equipment for obtaining electroplating coatings, developed a new electrolyte composition for obtaining high-quality high-performance chrome precipitation, as well as the Statistica 13.0 program, which allowed us to reduce the time for calculations and building the necessary graphs, was used.Results. The analysis of methods and methods of mathematical analysis of the results obtained in order to process them and build a model showed that with a confidence regression coefficient of 0.95, it is most preferable to study the effect of the composition of the chromating electrolyte on the current output, in the range of current density values from 125 ... 250 A / dm2 , the amount of hydrofluoric acid 0.6...1.2 g / l and the operating temperature of the electrolyte 16 ... 27 o C.Discussion and conclusion. As a result of the obtained mathematical model, it can be argued that studies of the influence of the electrolyte composition on the current density will allow to obtain reliable data with the least number of experiments. At the same time, it can also be argued that it is possible to obtain an even greater current output if additional research is carried out with a change in factors up or down. However, it is not known how the quality of the coating and the adhesion to the base of the part will change, which is an important factor in obtaining wearresistant electroplating.

Relevance. This work is devoted to modeling the stress-strain state of a high-rise brick building on a pile foundation in engineering and geological conditions using the MicroFe design and computing complex, which allows you to create a design scheme in the “base – foundation – building” system using piles in the form of rod end. elements in the soil mass.Goal. Analyzed-deformed state of the system “base – foundation – building”, obtaining the calculated values of tension and reinforcement in the grillage.Materials and methods. The calculation was carried out both in a linear formulation and in a constructively nonlinear formulation with one-sided nonlinear connections between bulk soil elements and pile bar elements. Results. In a nonlinear formulation of the solution to the problem, with a limitation of the permissible design load on the piles, a redistribution of efforts between the piles through the grillage is obtained. Conclusions. Linear calculation is carried out in the case when the greatest forces in the piles do not exceed the specified design load. If this condition is not met, then in the design model, a limitation is introduced on the value of the ultimate load on the piles, equal to the design value, and the calculation is performed considering the constructive nonlinearity of one-sided connections between the pile bar elements and bulk soil elements. Solving the problem in a non-linear formulation allows us to consider the redistribution of efforts between the piles through the grillage, because of which, by changing the location of the piles, it is possible to obtain an optimal design solution for both the pile foundation and the overhead part of the building.
