Random Actions in Experimental Zero-Sum Games
Authors: You Jung S.
Published: April 2021

A mixed strategy, a strategy of unpredictable actions, is applicable to business, politics, and sports. Playing mixed strategies, however, poses a challenge, as the game theory involves calculating probabilities and executing random actions. I test i.i.d. hypotheses of the mixed strategy Nash equilibrium with the simplest experiments in which student participants play zero-sum games in multiple iterations and possibly figure out the optimal mixed strategy (equilibrium) through the games. My results confirm that most players behave differently from the Nash equilibrium prediction for the simplest 2x2 zero-sum game (matching-pennies) and 3x3 zero-sum game (e.g., the rock-paper-scissors game). The results indicate the need to further develop theoretical models that explain a non-Nash equilibrium behavior.
Influence of the ringer's solution on wear of vacuum mixed poly(methyl methacrylate) bone cement in reciprocating sliding contact with AISI 316l stainless steel
Authors: Zivic Fatima , Grujovic Nenad , Mitrovic Slobodan , Tanaskovic Jovan , Todorovic Petar
Published: April 2021

This paper presents microstructural properties and damage behaviour of a
vacuum mixed poly(methyl metacrylate) (PMMA) bone cement, during the sliding
contact with AISI 316L stainless steel, under micro-loads. Influence of the
Ringer's solution on the wear was analysed in comparison to dry contact. The
variation of load did not produce any significant change of the wear factor
while the increase in the sliding speed induced significant increases in the
wear factor, more pronounced in the case of dry sliding. The obtained wear
factors were in average higher for the sliding in Ringer's solution than
those obtained under dry conditions. Significant fragmentation of the worn
tracks, of irregular shapes with broken edges, was observed, slightly more
pronounced for the dry contact. Many cavities and voids were formed on the
wear track surface, but they did not extend into the bulk material. Higher
loads produced more uniform and less fragmented wear tracks. Abrasive,
adhesive wear and plastic deformation grooves were observed, as well as
fatigue and erosive wear. Fatigue cracks developed in the direction normal
to sliding. Network of fine craze cracks was exhibited on the surface of
wear tracks, especially pronounced in the case of dry sliding. These results
are important since they contribute to understanding the sites of crack
initiation, and development mechanisms on the surface of PMMA bone cements,
also including synergistic effects of physiological environments pertaining
to the non-steady crack and craze behaviour and crack pattern development in
PMMA.
Effect of fabric surface’s cleanliness on its moisture/air permeability
Authors: Han Chunyu , He Ji-Huan
Published: April 2021

A fabric?s moisture/air permeability is a main factor for the fabric design
for advanced applications, and no theoretical model was available in
literature for an optimal permeability. In this paper, we use the
capillary-like effect to elucidate the permeability property, and the effect
of nano/micro particles on the fabric?s surface on the permeability is
studied by the geometric potential theory. Our theoretical analysis shows
that an unclean surface gives a negative impact on the permeability. A
superhydrophobic surface is needed to design a good and lasting moisture/air
permeability.

OBJECTIVE

The deletion (D) allele of the ACE insertion/deletion (I/D) polymorphism is a risk factor for diabetic kidney disease. We assessed its contribution to long-term kidney outcomes and all-cause death in patients with long-standing type 1 diabetes.

RESEARCH DESIGN AND METHODS

A total of 1,155 participants from three French and Belgian cohorts were monitored for a median duration of 14 (interquartile range 13) years. The primary outcome was the occurrence of end-stage kidney disease (ESKD) or a 40% drop in the estimated glomerular filtration rate (eGFR). Secondary outcomes were the individual components of the primary outcome, rapid decline in eGFR (steeper than –3 mL/min/1.73 m2 per year), incident albuminuria, all-cause death, and a composite ESKD or all-cause death. Hazard ratios (HRs) for XD versus II genotype and for baseline plasma ACE levels were computed by Cox analysis. Genotype performance in stratifying the primary outcome was tested.

RESULTS

Genotype distribution was 954 XD and 201 II. The primary outcome occurred in 20% of XD and 13% of II carriers: adjusted HR 2.07 (95% CI 1.32–3.40; P = 0.001). Significant associations were also observed for rapid decline in eGFR, incident albuminuria, ESKD, all-cause death, and ESKD or all-cause death. Baseline plasma ACE levels were higher in XD carriers and significantly associated with an increased risk of the primary outcome. The ACE genotype enhanced net reclassification improvement (0.154, 95% CI 0.007–0.279; P = 0.04) and integrated discrimination improvement (0.012, 95%CI 0.001–0.021; P = 0.02) for primary outcome stratification.

CONCLUSIONS

The D-allele of the ACE I/D polymorphism was associated with an increased risk of major kidney events and all-cause death in patients with long-standing type 1 diabetes.

Authors: Oda Wakana , Hanamoto Hiroshi , Oyamaguchi Aiko , Togawa Eriko , Honjyo Yuka , Usami Nayuka , Niwa Hitoshi
Published: April 2021

Preformed cuffed oral endotracheal tubes are widely used to intubate children undergoing oral surgery. To evaluate the efficacy and safety of oral Ring-Adair-Elwyn (RAE) Microcuff® pediatric endotracheal tubes, we retrospectively investigated the endotracheal tube exchange rate and associated complications in Japanese children younger than 2 years of age undergoing cheiloplasty or palatoplasty. The exchange rate was 3.5%, and although unplanned extubations occurred in 2 patients, no severe complications were observed. Our results suggest that oral RAE Microcuff® tubes are effective and safe for intubating Japanese children younger than 2 years of age, with a low tube exchange rate and minor complications.

EDUCAÇÃO INFANTIL COMO DIREITO, ALEGRIA E POSSIBILIDADE DE CRIAÇÃO E ENCONTROS
Authors: Louzada Virgínia , Ogg Gomes Lisandra
Published: April 2021

A Educação Infantil integra e é reconhecida como primeira etapa da educação básica, conforme a Lei de Diretrizes e Bases, n.º 9.394/1996. Entretanto, qualquer mudança no cenário político afeta com intensidade a proposta educacional para as crianças que frequentam a creche e a pré-escola. Nosso objetivo com este ensaio teórico é analisar e avaliar o debate político educacional-curricular na atualidade. Inicialmente, ponderamos sobre uma educação que considere as crianças a partir da dinâmica estabelecida entre socialização, políticas e infância, com base no campo dos estudos da infância. Na sequência, tratamos da avaliação voltada para as aprendizagens infantis, que não provoque epistemicídio, mas que torne possível a potência das crianças, assumindo e compreendendo com elas a diversidade da linguagem e do mundo. Concluímos defendendo uma Educação Infantil como direito e alegria, como possibilidade de criação e de encontros.
CORPO, “PRODUÇÃO DO COMUM” E CURRÍCULO: SOBRE A (IM)POSSIBILIDADE DE UMA BASE NACIONAL COMUM CURRICULAR
Authors: Correia Elder Silva , Zoboli Fabio
Published: April 2021

O texto tem como objetivo investigar a (im)possibilidade de uma Base Nacional Comum Curricular (BNCC) como documento norteador para a construção de propostas curriculares/pedagógicas para as escolas em todo o Brasil. Para tanto, interpelamos o termo “comum” a partir do conceito de “noções comuns” presente na filosofia de Baruch Spinoza e na análise que Gilles Deleuze faz de tal conceito. Concluímos que, para tomar para si a prerrogativa de falar em nome do comum, a BNCC precisou despontencializar os corpos, apresentando-os como incapazes de ser os próprios produtores de conhecimento e promotores de currículo.

Published: April 2021

Este artigo apresenta uma análise da Cultura Material do Xarope no cotidiano da Pastoral da Saúde em Bragança, Estado do Pará (PA), e a proposição do currículo cultural para o contexto escolar. A metodologia é a da Nova História Cultural na observação dos objetos de consumo, empregados para a produção do Xarope, cujas significações e sentidos possibilitaram a tessitura do currículo escolar. O uso de imagens, as entrevistas, o Caderno de controle da Pastoral da Saúde e os documentos digitais compuseram a coleta de dados. A análise dos dados sobreveio pela produção, circulação e apropriação, categorias defendidas por Certeau (2014) e Chartier (1991). Assim, a partir dos resultados, a pesquisa constatou que o currículo cultural está imerso por representações sobre “Saúde e Qualidade de Vida” na Pastoral da Saúde, em Bragança (PA).

Destaca-se: a importância da tomada de decisão e o suporte institucional de Secretarias de Educação para mudar de método educacional frente a situações de não melhoria da qualidade do ensino ofertado; partir do acúmulo de experiências da mesma natureza envolvendo todos os sujeitos da comunidade escolar; protagonismo das famílias ao exigir educação em suas comunidades.
A CULTURA DIGITAL NO CURRÍCULO: CENÁRIOS ATUAIS
Authors: Coutinho Lídia Miranda , Girardello Gilka
Published: April 2021

Este artigo discute algumas das principais diretrizes nacionais e internacionais para a abordagem da cultura digital na educação na última década, com vistas à sua inserção nos currículos e na formação de professores. No contexto brasileiro, destacamos a Base Nacional Comum Curricular (2017) que, seguindo a tendência internacional, organizou-se em competências e habilidades, não sem muitas críticas e polêmicas. O documento sugere a ampliação do protagonismo da cultura digital na construção dos currículos, o que permite que tanto os conteúdos quanto as estratégias didáticas para o trabalho com a cultura digital sejam definidos nos contextos regionais e locais. O artigo examina, também, o caso de Santa Catarina, onde o currículo regional (2019) sugere que a questão seja explorada e detalhada nos Projetos Políticos Pedagógicos das escolas, o que identificamos como uma brecha para que os professores participem das escritas curriculares, com base em suas realidades e experiências docentes em campo.

Método: Revisão integrativa de literatura desenvolvida em conformidade às seis etapas metodológicas. Foram selecionados todos os artigos que respondiam à questão de pesquisa até setembro de 2020, recrutados por dois pesquisadores independentes nas bases de dados: Pubmed, LILACS, MEDLINE, BDENF e CINAHL. Após emprego dos critérios de elegibilidade, nove artigos compuserem a síntese do conhecimento. Resultados: A busca inicial nas bases de dados resultou na seleção de 213 artigos, dos quais 209 foram excluídos por duplicidade ou por não preencherem os critérios de elegibilidade. Dos 09 artigos selecionados, 8 eram artigos originais e 1 de revisão de literatura. Os estudos eram provenientes de cinco estados brasileiros. Observou-se preocupação com a identificação das taxas de absenteísmo, as implicações do absenteísmo na qualidade do cuidado crítico prestado, às motivações para as ausências e intervenções com vistas a diminuir os índices de absenteísmo. Conclusão: As taxas de absenteísmo tendem a ser mais elevadas entre profissionais de enfermagem de nível médio. Dentre os motivos, destaca-se o relacionamento interpessoal ineficaz, sobrecarga de trabalho, falta de suporte psicossocial, duplo vínculo de trabalho e a falta de apoio para o aprimoramento profissional. Por fim, ficou evidente a necessidade de estudos de maior evidência no escopo pesquisado.

Published: April 2021

A análise descritiva (descriptive analytics) permite responder perguntas relacionadas ao que aconteceu durante um determinado período. Ao desenvolver indicadores chaves de desempenho, a análise das informações pode ajudar a rastrear atividades de sucessos ou fracassos. É possível gerar métricas especializadas para acompanhar o desempenho em setores específicos, como é o caso do ambiente hospitalar, ou mesmo identificar métricas necessárias para a análise e a melhoria da gestão. Esse processo requer coleta, processamento, análise e visualização de dados relevantes. Ele fornece uma visão essencial do desempenho no passado. Diante disso, a proposta do artigo está relacionada à aplicação da análise descritiva para identificar as atividades de desospitalização em um hospital universitário de grande porte da cidade de São Paulo (SP). O artigo também discorre sobre os principais conceitos correlatos entre a transição de cuidado e os indicadores de DRG (Diagnosis Related Groups), principalmente, taxa de reinternação hospitalar e eficiência do uso do leito. Baseada nessas análises busca-se influenciar os gestores hospitalares para que possam refletir e promover uma melhoria contínua nos processos relacionados à jornada do paciente.Palavras-chave: Estratégias de Saúde, Gestão Hospitalar, Cuidado de Transição, Assistência ao Paciente, Relatórios Públicos de Dados de Saúde. ABSTRACTApplication of descriptive analytics to understand the de-hospitalization activities of a large university hospital between 2009 and 2019Descriptive analytics allows you to answer questions related to what happened during a certain period.

Geographical information system is a system that combines elements on a map that is prepared to process data, analyze, and display spatial data to improve design. In the era of technology, information and communication (ICT) for organizations, agencies and public services is very important and needs to be implemented immediately. ATR / BPN in Jonggol village, Jabon, Ponorogo, still uses the manual method in processing certified land registration. The process of seeking, processing, and collecting certificate data requires a lot of time, causing services to be inefficient and effective and community satisfaction also decreasing. Therefore, a technology is needed that can facilitate service officers to search for certified land ownership data by implementing the brute force algorithm in the Geographical Information System for certified land ownership. The application of Algortima Brute Force in this geographic information system can run well, but if the text characters are long inputted, the system search process will take longer (if the text is short, the search can run quickly). On 10 keywords with different keyword or character lengths, the average search time was 0.06335 seconds.
The Quest of Young Turkish Playwrights: In-Yer-Face Theatre
Authors: Baş Elif
Published: April 2021

In-yer-face theatre, which emerged in Britain in the 1990s, became extremely popular on the stages of Istanbul in the new millennium. Some critics considered this new outburst as another phase of imitation. This phase, however, gave way to a new wave of playwrights that wrote about Turkey’s own controversial problems. Many topics, such as LGBT issues, found voice for the first time in the history of Turkish theatre. This study examines why in-yer-face theatre became so popular in this specific period and how it affected young Turkish playwrights in the light of Turkey’s political atmosphere.
Becoming a Legend: Edna O’Brien and Her Life-Long Journey
Authors: Zarebska Zuzanna
Published: April 2021

The publication of Germaine Greer’s The Change: Women, Aging and the Menopause presents a manifesto for women’s emancipation and their imminent embarkment on the avenue of freedom towards the liberation from the male gaze. In a similar vein, Edna O’Brien, a pioneer of the literary treatment of female agency and sexuality in the Irish literary canon, moves past the age when women enjoy visibility. Age liberates O’Brien from her entrapment in the public persona and her anxious relationship with the public opinion. It has the power to enhance the possibility of women’s difference. Nowadays, the commitment to women’s cause, the inherent element of O’Brien’s narratives, continues to mark out the uncompromising discourse of transgression of the standard as well as her vigilant condemnation of violence against women. In time, O’Brien has become both a foremother author and a legend. She has embraced her unrepressed femininity and the personification of a female sage that Irish women writers have long lacked and may thus represent a role model for authors who wish to transgress the discriminatory standards and defend the female voice.

Published: April 2021

The inoculation of plant species with mycorrhiza fungus Piriformospora indica results in enhancement of growth, increase in yield, and induction of resistance to biotic and abiotic diseases through improvement of the root system. The aim of the present study was to optimize in vitro propagation protocol for three indigenous apples (Malus × domestica) cultivars (ꞌGolbaharꞌ, ꞌSharbatiꞌ, ꞌSoltani Shabestariꞌ) and one commercial cultivar (ꞌGolden Deliciousꞌ). Furthermore, the efficiency of P. indica at rooting stage was investigated on three cultivars (ꞌSharbatiꞌ, ꞌSoltani Shabestariꞌ, ꞌGolden Deliciousꞌ). Establishment and proliferation stages were optimized by collecting explants at different seasons and comparing different culture media respectively. Rooting optimization included six treatments containing different concentrations of auxins in the presence or absence of P. indica. Results showed that at the establishment stage, a maximum percent of survival was observed in explants collected in spring. At the proliferation stage, different media had a divergent effects on distinct cultivars. Although all cultivars reacted favourable to micropropagation in MS (Murashige & Skoog 1962) basal medium, the presence or absence of cytokinin 2ip (N6-(2-Isopentenyl) adenine) in the culture media showed significant and incremental improvements in growth indices. In all cultivars highest rooting percent, root length, root thickness, and the number of roots/explant was observed in MS media containing auxins for three weeks followed by a treatment of MS medium containing P. indica for another three weeks. Plantlets treated with P. indica, grow stronger and healthier at the acclimation stage compared to the ones that excluded P. indica.

We took samples of uncultivated soil from the surface layer (0–10 cm) at 138 sites from all over Croatia and measured their radionuclide activity concentrations with high-resolution gamma-ray spectrometry. This second part of our report brings the results on 40K and 137Cs to complement those on the 232Th and 238U decay chains addressed in the first part. Together they give the most complete picture of radioactivity of Croatian soil so far. Activity concentrations of 40K were the highest in the Pannonian region, and there was an opposite trend for 137Cs. We found that the concentrations of 137Cs tended to increase with altitude, annual precipitation, and vegetation density. The concentration ratio of 137Cs and K in soil, which indicates the potential for 137Cs entering food chains via uptake by plants, was the lowest in agriculturally important areas in the east of the Pannonian region. In addition, we used the obtained results on activity concentrations to calculate the related absorbed dose rate as a measure of external exposure to ionising radiation from soil. The sum of the absorbed dose rates for naturally occurring radionuclides and 137Cs showed that external exposure was generally the highest in the Dinaric region and Istrian Peninsula.
New Opportunities for Increasing the Renovation Rate of Buildings
Authors: Sonnleithner Manfred
Published: April 2021

The paper focuses on the long-standing problem of too low renovation rates of existing buildings and on practice-oriented solutions. The European Commission has set the goal of at least doubling the renovation quota with “The European Green Deal” and published the “Strategy for a Renovation Wave for Europe - greening our buildings, creating jobs, improving lives” on 14 October 2020. As in previous years, technical specifications have been defined even more strictly and limit values for energy consumption have been further reduced with the aim to reduce CO2 emissions. The high quality of the renovation measures is ensured within the European Union and its member states. However, this has not yet been the case in relation to the quantity of implemented renovation projects. The thesis investigates which factors were neglected or were not taken into consideration sufficiently in the past, and, because of that, countries like Austria could not achieve their goals with regard to the renovation rates. This is done by identifying, selecting and verifying both specific and potential conflicting goals. On the basis of the description and analysis of the background to these potential conflicts, the actual obstacles are identified and approaches to their solutions are defined. The formulated approaches should form the basis for future in-depth discussion and further development of specific detailed solutions. The implementation of these results in a comprehensive package with technical regulations such as the “Renovation Wave for Europe” and “The European Green Deal”, opens up new opportunities for achieving the set goals. An increase in the renovation rate of existing buildings is the quantitatively measurable outcome.

Published: April 2021

Innovative technologies help automate the work of the designer. A 3D model of the building can be used to calculate the required values. This will also allow you to create associative sections that, when changing the geometry of the 3D model, automatically adjust the drawn elements on the resulting 2D drawing. Information technologies enable participants from all over the world to work on one project and, thanks to the BIM (building information modelling) method, to design buildings during their life cycle more efficiently. At present, critical studies are published on interoper-ability in BIM and its lack of coordination or amount of information that is misinterpreted, etc. However, working in BIM is the most effective way to use computer technology to design buildings. There is a lot of information about the building in the 3D model itself, which can also be used for purposes other than construction (building management, reconstruction). But how to process a large amount of information in a 3D model? Many buildings already have their 3D models shared on cloud platforms, these contain information that could help, for example, find solutions for green construction using artificial intelligence (AI). We meet with AI every day. It supports internet search engines, predicts auto-completion words as you type. AI can also be found in architecture – not only as visions at exhibitions, but also in research on process optimization in BIM.
Effect of Kerr Foundation and in-Plane Forces on Free Vibration of FGM Nanobeams with Diverse Distribution of Porosity
Authors: Jankowski Piotr
Published: April 2021

In the present paper, the effect of diverse distribution of functionally graded porous material and Kerr elastic foundation on natural vibrations of nanobeams subjected to in-plane forces is investigated based on the nonlocal strain gradient theory. The displacement field of the nanobeam satisfies assumptions of Reddy higher-order shear deformation beam theory. All the displacements gradients are assumed to be small, then the components of the Green-Lagrange strain tensor are linear and infinitesimal. The constitutive relations for functionally graded (FG) porous material are expressed by nonlocal and length scale parameters and power-law variation of material parameters in conjunction with cosine functions. It created possibility to investigate an effect of functionally graded materials with diverse distribution of porosity and volume of voids on mechanics of structures in nano scale. The Hamilton’s variational principle is utilized to derive governing equations of motion of the FG porous nanobeam. Analytical solution to formulated boundary value problem is obtained in closed-form by using Navier solution technique. Validation of obtained results and parametric study are presented in tabular and graphical form. Influence of axial tensile/compressive forces and three different types of porosity distribution as well as stiffness of Kerr foundation on natural frequencies of functionally graded nanobeam is comprehensively studied.

Published: April 2021

Due to their impressive capacity of sensing and actuating, piezoelectric materials have been widely merged in different industrial fields, especially aeronautic and aerospace area. However, in the aeronautic industry, the structures are operating under critical environmental loads such as high and very low temperature, which made the investigation of the effect of thermal forces on the piezoelectric structures indispensable to reach the high functionality and performance. The present paper focuses on the effect of thermal loads on the active vibration control (AVC) of structures like beams. For this purpose, a finite element model of composite beam with fully covered piezoelectric sensor and actuator based on the well-known high order shear deformation theory is proposed by taking into account the electrical potential field and a linear temperature field. Hamilton’s principle is used to formulate the electro-thermo-mechanical governing equations. The negative velocity feedback controller is implemented to provide the necessary gain for the actuator. Different analyses are effectuated to present the effect of the temperature ranging from -70°C to 70°C on the active vibration control of the composite beam.

Ebola: History and some implications for Africa
Authors: Pavlik Ivo , Lategan François , Verter Nahanga
Published: April 2021

The Ebola disease derives its name after a small river, the Ebola River, flowing through the former Zaire (present day DR Congo) and was formally named in 1976. The disease belongs to the category of diseases referred to as “haemorrhagic fever”; the causal agent – a filovirus (from Latin “filo” = thread) belonging to the Filoviridae family. The treatment of Ebola has been only symptomatic, i.e. based on mitigation of the symptoms related to the infection, such as kidneys and liver. An effective vaccine has not been developed yet, even though rigorous attempts have been made and reported. Ebola has been primarily found in the Ivory Coast, DR Congo, Sudan, Gabon and other equatorial African countries. Based on the data obtained during the latest epidemics, people are strongly advised to avoid direct contact with patients, avoid buying bush meat in street markets and not handle dead bats, megabats, monkeys or gorillas. Estimated data suggest that more than 5,000 of these animals have died. The disease was also diagnosed in patients in the USA and Europe. The epidemic afflicted West Africa and had significant implication on their economy in terms of lost production, higher fiscal deficits, rising prices and lower real household incomes, leading to greater poverty.
Heritage in a Globalised World: Pilot Study for Perception by Analysis of Buildings’ Potential
Authors: Doğan Huriye Armağan
Published: April 2021

Heritage connects the past and present, but at the same time it connects people with each other and with the place itself. The perception of heritage regarding the built heritage can be a problematic issue in the globalised world, since it might not be easy to relate to an artefact that is not necessarily one’s own, or an environment, which does not carry the characteristics that one is used to. This research aims to understand the constraints of the perception of built heritage by using the Modern Movement artefacts and tries to analyse the perception of different societies by a pilot survey. The pilot survey suggests that prior knowledge and public awareness has a colossal impact on the perception or evaluation of the built heritage.

Donald Duck Holiday Game: A numerical analysis of a Game of the Goose role-playing variant
Authors: van Heeswijk W.J.A.
Published: April 2021

The 1996 Donald Duck Holiday Game is a role-playing variant of the historical Game of the Goose, involving characters with unique attributes, event squares, and random event cards. The objective of the game is to reach the camping before any other player does. We develop a Monte Carlo simulation model that automatically plays the game and enables analyzing its key characteristics.

We assess the game on various metrics relevant to each playability. Numerical analysis shows that, on average, the game takes between 69 and 123 rounds to complete, depending on the number of players. However, durations over one hour (translated to human play time) occur over 25% of the games, which might reduce the quality of the gaming experience. Furthermore, we show that two characters are about 30% likely to win than the other three, primarily due to being exposed to fewer random events. We argue that the richer narrative of role-playing games may extend the duration for which the game remains enjoyable, such that the metrics cannot directly be compared to those of the traditional Game-of-the-Goose.

Based on our analysis, we provide several suggestions to improve the game’s balance with only slight modifications. In a broader sense, we demonstrate that a basic Monte Carlo simulation suffices to analyze Game-of-the-Goose role-playing variants, verify how they score on criteria that contribute to an enjoyable game, and detect possible anomalies.

Study aim. The purpose of the current study is to determine the impact of single bouts of physical exercise of different duration and intensity on young adults’ executive functions.

Material and methods. The study employed 81 participants (37 females, 44 males) ranging between 19 and 39 years (mean age: 24.6 ± 4.08 years; mean height: 168 ± 9.67 cm; mean weight: 67.2 ± 13.0 kg). The executive functions were assessed through the Stroop task, the Tower of London test, and the Corsi block test. Participants were randomly assigned to one of the three experimental conditions (30-second Wingate test condition, an incremental intensity exercise test, and a submaximal constant-intensity test) or the control group.

Results. For all the conditions, repeated measures ANOVA revealed a significant effect of time on executive function performances, meaning that participants improved their performance between pre-test and post-test, while the interaction time x activity was in the expected direction but nonsignificant.

Conclusions. Apparently, a single, brief, high-intensity bout of exercise has no effects on young adults’ cognitive functions, but the same experiment should be replicated with a bigger sample.

Local distribution pattern of Virga pilosa (L.) Hill. (Dipsacaceae) as an effect of its life and dispersal strategy
Authors: Bernard Rafał , Chmiel Julian
Published: April 2021

A new locality of regionally alien and rare Virga pilosa was recorded outside the compact range of the species in the Wielkopolski National Park, midwestern Poland. It probably appeared as a result of unintentional anthropochory. Local distribution pattern of V. pilosa in micro- and mesoscale was described and interpreted in the light of life and dispersal strategy and habitat conditions of the species. Accidental epizoochory and unintentional anthropochory could have been responsible for the mesoscale distribution pattern with population units scattered along human and animal communication routes. Close dense autochory together with the species CR life strategy with a strong competitive component were responsible for microscale distribution pattern alternating in space and time, but always mosaic, including vegetative, generative and mixed patches. The distribution pattern was also influenced by the occurrence of the required combination of the moderately light, moderately moist and nitrogen-rich habitat conditions with favourable human-induced disturbance. Some data on the form of growth, reproductive potential and dispersal mode of the species, as well as on plant-animal interactions were also included.
Einfluss von Regenmustern auf Splash-Erosion von sandigem Lehm
Authors: Loos Lorenz , Zambon Nives , Klik Andreas
Published: April 2021

Die Wirkung unterschiedlich intensiver Regenereignisse auf Splash-Erosion ist noch nicht genau bekannt. Um diese zu untersuchen, wurde sandiger Lehm in einem Laborversuch durch einen Starkregensimulator mit zunehmender, abnehmender oder konstanter Regenintensität beregnet. Alle Intensitätsabfolgen wiesen im Mittel eine Regenintensität von 24,7 mm h−1 auf und bestanden aus drei Intensitätsstufen mit einer Beregnungsdauer von je 20 min. Der ausschließlich durch Splash-Erosion abgetragene Boden wurde nach jeder Beregnungsphase gesammelt. Die Ergebnisse zeigen, dass Regenereignisse mit hoher Intensität am Anfang zu 32 % mehr Splash-Erosion führen als jene mit maximaler Intensität am Ende. Die kumulativ wirkende kinetische Energie der Regentropfen, verstärkt durch einen dünnen Wasserfilm auf den Proben, führt dazu, dass die Splash-Erosion am Ende einer Simulation stärker wirkt als zu Beginn. Aus den Untersuchungsergebnissen kann zudem durch Extrapolation der Regressionsgeraden eine minimale Regenintensität zwischen 10 mm h−1 und 15 mm h−1 zur Erzeugung von Splash-Erosion angenommen werden.
A new two-component approach in modeling red blood cells

Published: April 2021

This work consists in the presentation of a computational modelling approach to study normal and pathological behavior of red blood cells in slow transient processes that can not be accompanied by pure particle methods (which require very small time steps). The basic model, inspired by the best models currently available, considers the cytoskeleton as a discrete non-linear elastic structure. The novelty of the proposed work is to couple this skeleton with continuum models instead of the more common discrete models (molecular dynamics, particle methods) of the lipid bilayer. The interaction of the solid cytoskeleton with the bilayer, which is a two-dimensional fluid, will be done through adhesion forces adapting e cient solid-solid adhesion algorithms. The continuous treatment of the fluid parts is well justified by scale arguments and leads to much more stable and precise numerical problems when, as is the case, the size of the molecules (0.3 nm) is much smaller than the overall size (≃ 8000 nm). In this paper we display some numerical simulations that show how our approach can describe the interaction of an RBC with an exogenous body as well as the relaxation of the shape of an RBC toward its equilibrium configuration in absence of external forces.
Lower-Secondary School Chemistry Textbooks’ Didactic Equipment
Authors: Rusek Martin , Vojíř Karel , Šubová Šárka
Published: April 2021

Textbooks’ fundamental influence on teaching is caused not only by their subject matter, but also by their didactic elaboration. Textbooks’ individual functions are fulfilled through incorporated structural elements. Their pool is referred to as the didactic equipment of the textbook and represents qualities of the textbook through the options it gives to its users. The presented overview of lower-secondary chemistry textbooks’ didactic equipment included 7 series of currently available textbooks. Results of the analysis serve not only as a possible guide for chemistry teachers’ textbook selection, but they also provide insight into the current state to authors of textbooks and other didactic materials. Chemistry textbooks for lower-secondary schools achieve relatively high didactic equipment (75-92 %). The best equipped are the series of textbooks published after the current state curriculum introduction (by publishing houses Fraus and Nova Skola). Surprisingly, however, the most recently published textbooks by the Taktik publishing house showed the lowest didactic equipment.
Stability of Anchored Retaining Walls Under Seismic Loading Conditions to Obtain Minimal Anchor Lengths Using The Improved Failure Model

Published: April 2021

Anchored retaining walls are structures designed to support different loading applied in static and dynamic cases. The purpose of this work is to design and study the stability of an anchored retaining wall loaded with different seismic actions to obtain minimal anchor lengths. Mononobe-Okabe theory has been applied for the evaluation of seismic earth pressures developed behind the anchored wall. Checking the dynamic stability of anchored retaining walls is usually done using the classic Kranz model. To take into consideration the effects of the internal forces developed during failure, we have proposed a new model, based on the Kranz model, which will be used as the Kranz model to find the critical angle failure performed iteratively until the required horizontal anchor length is reached for a minimum safety factor. The results of this study confirm that the effect of the seismic load on the design of an anchored retaining wall, and its stability, has a considerable influence on the estimation of anchor lengths. To validate the modifications made to the new model, a numerical analysis was carried out using the Plaxis 2D software. The interpretation of the obtained results may provide more detailed explanation on the effect of seismic intensities for the design of anchored retaining walls.
