Published: July 2024

O Squash é uma modalidade esportiva praticada intensamente ao redor do mundo, e devido ao crescimento de sua prática o esporte participou da préseleção para a inclusão dos jogos olímpicos de 2020. Esse esporte exige diversas habilidades físicas e como qualquer outro esporte, expõe seus praticantes ao risco de lesões, o que reforça a necessidade de compreender os gestos esportivos, as demandas físicas que a modalidade impõe, e as lesões mais frequentes nesses atletas, para que assim seja possível a implementação de protocolos que reduzam o risco de lesões. Dessa forma, o objetivo desse estudo foi expor a história, as regras, os gestos esportivos, e as lesões mais prevalentes em praticantes de Squash, e propor um protocolo fisioterapêutico preventivo para a redução de lesões e para a melhora da performance nesses atletas. A busca foi realizada nas bases de dados PubMed, SciELO e Scholar Google incluindo artigos que se referiam ao Squash, na língua inglesa e portuguesa dos anos de 2003 a 2020, e no site da Confederação Brasileira de Squash. Os artigos exploraram três grandes itens referentes ao Squash: 1) o Squash como modalidade esportiva; 2) incidência de lesões; e 3) treinamento sensório-motor, nos quais exploraram itens como a história, regras, gestos esportivos próprios da modalidade, lesões mais frequentes, e por fim, os benefícios de um tratamento preventivo para esses atletas. Dess a forma, foi possível maior esclarecimento sobre a modalidade Squash, além de identificar as lesões mais frequentes nessa modalidade como as tendinopatia do manguito rotador e a epicondilite lateral, e por fim, foi proposto aos praticantes de Squash, um protocolo fisioterapêutico preventivo utilizando o treinamento sensório-motor.

Para um controle efetivo da intensidade de carga num programa de treinamento, escalas como a percepção subjetiva do esforço (PSE), são ferramentas de grande valia. Para tanto, essa pesquisa teve como objetivo verificar as possíveis diferenças no resultado da PSE, quando da não visualização das cargas de treino, em detrimento da prévia visualização das cargas, obtidas tendo o conhecimento do peso estipulado, em 20 praticantes de musculação, com média de idade de 32.3 ± 6.5 anos, sendo 10 do sexo masculino e 10 do sexo feminino, em uma academia de Curitiba. Para avaliar a PSE dos indivíduos durante a realização dos exercícios rosca bíceps (RB) e extensão de pernas (EP) foi utilizada a escala OMNI-RES. As cargas utilizadas foram de 8 RM (resistência máxima), tanto na primeira etapa onde os indivíduos não tiveram o conhecimento acerca da carga, pois não visualizaram a mesma, quanto na segunda etapa, onde os participantes puderam ter o acesso visual da quantidade de peso a ser vencida. Os dados foram analisados tendo como referência os critérios de normalidade de ShapiroWilk e para a comparação entre as duas fases do teste, foi utilizado o teste (t) de student dependente, sendo consideradosignificância de 5%. Conclui-se que homens e mulheres obtiveram uma taxação da resposta maior, somente quando da comparação entre a PSE, sem privação, para o exercício EP, sendo essa responsável por provocar um maior impacto psicológico no indivíduo durante a prática, quando da comparação entre as duas fases do teste.

Published: July 2024

During the last decade, low-cost airlines have dominated the European air transport market. The low-cost airline industry is expected to grow at a compound annual growth rate (CAGR) of more than thirteen percent from 2022 to 2027. In this study, we conducted a comparative case study analysis to analyse and compare the entrepreneurial behaviour of two of the most prominent players in the airline industry (Ryanair and Wizz Air). For example, our first research framework was used to examine how Ryanair and Wizz Air applied entrepreneurial behaviours (innovativeness, proactiveness, and risk-taking) to respond to changes due to Brexit and the Covid-19 pandemic. According to the results from the study’s first framework and second framework (the process of foresight), Wizz Air responded more innovatively and proactively to the changes caused by Brexit and the Covid-19 pandemic. Lastly, this study found that in comparison with Ryanair, Wizz Air was able to adapt its business model more efficiently to changes in its external environment.

Assessment of the Rationality of Design Solutions of Sound-Insulating Lightweight Partitions with Shotcreted Claddings
Authors: KUZMIN D.S. , MONICH D.V. , GREBNEV P.A. , POROZHENKO M.A.
Published: July 2024

In modern construction practice, partition structures are often used that do not meet regulatory requirements for airborne noise insulation. This reduces the acoustic comfort and safety of people in the rooms. An urgent task of building acoustics is to find structural solutions for enclosures with the required sound insulation properties and minimum values of surface density and thickness. New design solutions were considered: a lightweight frameless partition with acoustic isolation of the shotcreted claddings and the middle layer; lightweight frameless partition with acoustic separation of layers and fragmented shotcreted claddings. As analogues currently used in the design and construction of civil buildings, lightweight single-layer partitions made of tongue-and-groove gypsum slabs, gas silicate blocks, monolithic gypsum concrete, as well as multilayer lightweight frame-sheathing partitions are considered. A methodology has been developed for assessing the rationality of new design solutions for sound-insulating lightweight partitions in comparison with analogues. At the first stage of the assessment, enclosures that do not meet regulatory requirements for the value of the airborne noise insulation index are excluded. After this, a comparative analysis of the design solutions of the partitions is carried out according to two parameters: surface density and thickness. The results of the completed assessment are presented in tabular and graphical forms. An evaluation of a lightweight partition with shotcreted claddings in comparison with a frame-sheathing partition showed the rationality of the new type of enclosure in terms of surface density. The developed methodology for assessing rationality is recommended for use in the design of civil buildings. This will eliminate the use of lightweight partitions that do not meet regulatory requirements and select rational design solutions without inflated values of surface density and thickness.
Modeling of Bolts and Contact Interactions in a Finite Element Model of a Flange Connection
Authors: ALEKSEEVA A.S. , BUZALO N.A. , CHERNYHOVSKY B.A.
Published: July 2024

Analysis of the strength of bolted joints is a common task in the design of buildings with a metal frame. As a rule, such calculations are performed by analytical methods. However, today there are many calculation programs that make it possible to analyze the strength of steel structures using the finite element method. The capabilities of such advanced CAE programs make it possible to create calculation models of flange connections with detailed elaboration. At the same time, the issue of justifying the use of computing resources and the correct balance between simplifying the model and the correctness of the results is becoming increasingly relevant. The relevance of this issue is due to the fact that detailed finite element models of the analyzed structures can reach a dimension of 105–106 elements, which, when performing dynamic or nonlinear static calculations, leads to the need for high computational resources. The article considers the need to take into account such factors as the tightening force of the bolt, the presence of the bolt body when modeling the flanged joint assembly of a steel frame (frame assembly) for subsequent static and dynamic analysis of the structure. Conclusions are drawn about the permissibility of various simplifications of the model, allowing to reduce the computing resources necessary for the calculation.

It has become the guiding principle for long-term global development. Sustainable development involves the achievement of three fundamental goals: economic and social progress and environmental protection. The construction of healthy buildings involves, first of all, the creation of a favorable internal environment for future inhabitants, but also includes issues of environmental protection and the labor of builders. Green certification of residential buildings in Russia not only promotes more sustainable use of resources and reduces environmental impact, but also creates favorable conditions for the health and comfort of residents. Within the framework of this publication, the authors analyzed the advantages of using green certification of buildings, examined in detail the economic benefits of green certification, analyzed the process of certification of buildings, analyzed the advantages of green certificates using the example of commissioned buildings, considered the difficulties of introducing green certification, and identified prospects for the development of green certification in construction residential buildings.
A Probabilistic Approach to Design of Steel Trusses with Incomplete Statistical Data
Authors: SOLOVIEVA A.A. , SMIRNOV V.A. , SOLOVIEV S.A.
Published: July 2024

One of the promising directions of development of structural design standards is the transition to full probabilistic methods of structural design for a given target reliability level. For estimation of the reliability index, effective accounting and modeling of aleatory and epistemic uncertainties of data is necessary. The article describes a probabilistic approach to the design of steel truss elements taking into account incomplete statistical data. This approach allows giving an estimate of the failure probability for a steel truss under uncertainty data. The failure probability presented in the form of an interval that will narrow as additional statistical data about loads, material properties, geometric imperfections, etc. grows. To solve this problem, the article uses two numerical approaches to calculate the failure probability: discretization of p-boxes into Dempster-Shafer structures and the interval Monte Carlo (IMC) method. The use of the presented approach in practice also allows performing a comparative evaluation of different technical and economic solutions of steel trusses based on the reliability factor.
New Set of Rules 415.1325800.2023 on Acoustic Design of Sports and Entertainment Facilities
Authors: PERETOKIN A.V. , SHCHIRZHETSKII H.A.
Published: July 2024

Code of Rules 415.1325800.2018 “Public buildings. The Rules of Acoustic design”, which was released in 2018, contains methods of acoustic design of indoor sports and entertainment facilities with a capacity of up to 25 thousand people, the air volume of which is limited to 50 thousand m3. However, over the past 10 years, massive construction of large sports arenas with a capacity of more than 50 thousand people and an air volume of more than 500 thousand m3 has begun in Russia. In addition, all modern sports facilities are designed and built as multifunctional playgrounds, where, in addition to sports competitions, concert and entertainment events can also be held. Thus, the approaches and methods of acoustic design outlined in the 2018 Set of Rules currently do not meet the features of modern sports arenas with large capacity and large air volume, in which it is important to ensure a high level of acoustic comfort. The article presents a new Set of rules 415.1325800.2023 “Public buildings. Rules of acoustic design”, which proposes modern approaches to determining the optimal reverberation time depending on the air volume of the room. An additional parameter for the normalization of acoustic comfort is considered – the FSI fan support index. The data on the sound-absorbing characteristics of modern materials used in the decoration of arenas are updated. Simple analytical algorithms for estimating reverberation time in open, semi-open and closed arenas are proposed.

Thermal insulation materials used in external enclosing structures, depending on their basic properties, design solutions implemented with their help, the quality of their manufacture and installation, and taking into account the peculiarities of the operating mode, can perform their functions with varying efficiency. This can significantly affect the heat consumption of building heating systems. The paper presents the result of an ongoing experiment to assess the energy consumption of buildings depending on the type of structure and characteristics of their external fences. The test results confirmed the existence of a connection between the intense wind impact on the facade of the building, the air permeability of the enclosing structure and its individual constituent layers and the parameters of the air heating system.

W ramach niniejszej pracy podjęto problematykę wyzwań i perspektyw edukacji w kontekście systemu więziennego, ze szczególnym uwzględnieniem potrzeb więźniów oraz dostępnych zasobów i możliwości. Celem badania było określenie relacji między nasileniem różnych aspektów postawy wobec edukacji u więźniów a percepcją własnej skuteczności. Badanie przeprowadzono na 115 osobach odbywających karę pozbawienia wolności w jednostkach penitencjarnych Okręgu Lubelskiego Służby Więziennej. Analizy empiryczne wykazały istotne korelacje między emocjonalnym aspektem postawy wobec edukacji a percepcją własnych sukcesów i porażek, poziomem odczuwanego stresu oraz perswazjami ze strony innych osób. Intensywność poznawczego wymiaru postawy wobec edukacji istotnie koreluje z poziomem percepcji perswazji ze strony innych osób, z kolei intensywność wymiaru behawioralnego koreluje z poziomem doświadczanego stresu. Więźniowie mogą równocześnie wykazywać sprzeczne przekonania na temat edukacji, które mogą być zarówno pozytywne, jak i negatywne, jednocześnie doświadczając dużego poziomu stresu, co wskazuje na straty zasobów, oraz odnosząc sukcesy, co odbija się na zyskach kapitałowych.
MEMBRANE PROPERTY OPTIMIZATION FOR TREATMENT OF TEXTILE INDUSTRIAL EFFLUENT
Authors: Ranaware P. S. , Chaudhari P. L. , Bandpatte S. C. , Ajmal Mohd. , Bhatt D.P. , Chendake Y. J.
Published: July 2024

Textile industry wastewater is rich in color, has a low BOD/COD ratio, and contains high levels of salts (TSS and TDS). There is the presence of heavy metals at high concentrations. This has a major environmental impact underlined by chemical oxygen demand (COD) and biochemical oxygen demand (BOD). These issues arise from the presence of dye, pieces of fiber, and other surface treatment agents viz., detergents, salts, and caustic soda. Hence membrane optimization is investigated for treatment and recovery of these components, which would provide both economic and ecological benefits. It was required to provide chemically stable membranes, which would provide efficient separation for these components at effluent conditions of pH, temperature, and other parameters. A major challenge here was a selection of membrane and backing material with sustainability at low pH conditions of textile effluent. Hencepolysulfone (PSF) based membranes with cellulose as backing were optimized and tried for clarification of textile effluent. These membrane properties were further optimized for the recovery of other components. Membrane formation and performance were optimized with the proposition of a two-stage process for clarification and further concentration. Formed membranes showed excellent removal of impurities, validated by ICPMS. The clarified solution can be further treated for concentration enhancement from 7 to 20 %. Such recovered alkaline solution can be recycled or used in further applications. This solution provides an economically attractive and environmentally benign process. Further, it provides the advantages of low energy consumption, high efficiency in separation, and non-thermal processing of sensitive composite products.

Structure, Age, and Evolution of the Late Mesozoic East Mongolian Volcanic Belt
Authors: Yarmolyuk V. V. , Kozlovsky A. M. , Kudryashova E. A. , Oyunchimeg Ts.
Published: July 2024

Geochronological studies of volcanic rocks ascribed to the Late Mesozoic East Mongolian volcanic belt (EMVB) allow to distinguish several groups among them that differ in age and composition of igneous associations, as well as in the features of their distribution within the region. The earliest group (about 215 Ma) is represented by rocks of the bimodal association distributed in the western part of the EMVB. The next group (170–150 Ma) is predominantly formed by felsic lavas of the shoshonitic–latite association, which compose large volcanic fields in the eastern part of the EMVB. The rocks with an age of 140–105 Ma form the EMVB cover and are predominantly represented by trachyandesite basalts, whose fields are accompanied by small volcanoes of trachydacites and trachyrhyolites. Separate groups of extrusions of alkaline basaltoids were formed in the interval of 105–80 Ma.
The rocks of different age associations are characterized by different geological position. The age and composition of the Late Triassic bimodal complex are compared with similar associations developed in central Mongolia and Western Transbaikalia framing the Khentey-Daur batholith. Their formation is associated with the evolution of the Early Mesozoic Khentey-Daur zonal magmatic area. Middle–Late Jurassic igneous complexes are distributed mainly in the eastern part of the EMVB. The fields of their outcrops fit into the distribution zone of the Late Jurassic volcanic fields of the Great Xing’an volcanic belt, with which they are close both in the formation time and composition of volcanic associations. Cretaceous magmatism determined the main history of the formation of the EMVB. Its development was accompanied by rifting of numerous depressions and grabens, as well as the regular evolution of its mantle sources, directed towards an increase in the proportion of the intraplate component.
The dimensions, boundaries, and characteristics of the EMVB magmatism have been refined. The western boundary of the region is displaced to the east and is determined by a NW-trending end fault system that controls a chain of Early Cretaceous granite massifs, as well as rocks of the Late Cretaceous extrusive complex. The eastern boundary of the region is shifted to the west, where it coincides with the area of development of the rocks of the Early Cretaceous extrusive complex. Taking into account the data on the foreign position of the Late Triassic and Middle–Late Jurassic complexes in the structure of the EMVB, it has been established that the composition of the magmatic products of the belt is mainly determined by basic volcanic rocks. This is consistent with the idea that the EMVB is similar to other Late Mesozoic volcanic areas of the inland part of East Asia, in whose structure the proportion of felsic igneous rocks is subordinate.
