A Low Order Coupled Modelling Approach to the Hydrodynamics of Floating Tidal Energy Converters
Authors:   , Hughes Jack
Published: May 2022

Floating Tidal Energy Converters (FTECs) can be desirable over fixed foundation al-ternatives for their accessibility and relative ease of deployment and decommissioning, although highly energetic and harsher environmental loading near the sea surface, inter-actions with mooring lines and platform motion are additional complexities that must be considered. Despite a rising number of FTEC developers, computationally efficient open-source modelling tools remain few and far between. Computational fluid dynamics has been used, but with associated computational overhead. Therefore, an approach for mod-elling the operational system dynamics of FTECs is presented in this thesis and validated against physical modelling of the Sustainable Marine Energy FTEC device, PLAT-I. The coupled model utilises extensively validated, open-source, low order modelling codes from the wave energy sector for the floating platform hydrodynamics. This is extended to the modelling of FTECs with a modification allowing uniform or transient tidal currents and loading to be modelled via a drag coefficient approximation, which accounts for motions of the platform relative to the fluid. Operational turbine thrust and torque loads are solved using Blade Element Momentum Theory, with system interactions handled using multi-body dynamics. The ability to model coupled FTEC system in transient conditions in rela-tively short time and standard desktop configuration sets this approach out amongst others, which is demonstrated in a range of conditions and device scales. Firstly, tank-scale testing is simulated and agreement with platform motions was generally found to be within 20%over multiple wave climates and directions, including waves on the beam perpendicular to the dominant current direction. Then simulations are compared against motion data mea-sured in-situ at full-scale device testing, where the transient current approach is utilised and demonstrates the ability to model less controlled conditions. Using the presented re-search as a starting point, suggestions of future research routes are discussed with the intention of extending the application of the model to different FTEC designs and opera-tional environments, thus becoming a useful tool in commercial and academic applications alike.

Authors: Schrenk Maykon Jhonatan , Vertuan Rodolfo Eduardo
Published: May 2022

Neste artigo apresentamos uma caracterização de Modelagem Matemática, tomada na perspectiva da Educação Matemática, como prática pedagógica. A partir de uma revisão de literatura sobre Modelagem Matemática, suas características e modos de fazer, e sobre prática pedagógica, identificamos convergências entre os aspectos da realização de uma atividade de Modelagem no contexto escolar e as caracterizações de aspectos das práticas pedagógicas na perspectiva considerada, de modo a construir um entendimento de Modelagem Matemática a partir das convergências identificadas. Neste contexto, destacamos que a prática pedagógica de Modelagem se inicia muito antes e se estende para além da realização da atividade em sala de aula, denotando a importância do planejamento e da reflexão sobre a prática pelos professores. Ela também possibilita que os estudantes compreendam a importância da matemática para sua formação e para o enfrentamento de diferentes situações como uma lente possível para a leitura do mundo.
Estratégias didático-metodológicas com o software Criba de Eratóstenes no ensino e na aprendizagem dos critérios de divisibilidade
Authors: Gonçalves Ingrid Lara Rodrigues , Figueira-Sampaio Aleandra da Silva , Santos Eliane Elias Ferreira dos
Published: May 2022

A Matemática é considerada uma disciplina difícil pelos alunos do ensino fundamental ao ensino superior. Com isso, os professores procuram métodos de ensino e aprendizagem prazerosos e interessantes, buscando contextos que envolvem a realidade e o cotidiano dos alunos. A divisibilidade é um dos conceitos mais importantes na Teoria dos Números. Portanto, requer esforço dos educadores no sentido de desenvolver estratégias que favoreçam a sua compreensão em detrimento da mera memorização de regras. As dificuldades na aprendizagem da divisão se estendem para a compreensão dos critérios de divisibilidade. Neste sentido, o objetivo do trabalho foi desenvolver estratégias didático-metodológicas com o software Criba de Eratóstenes para o ensino e a aprendizagem dos critérios de divisibilidade por 3 e por 5. Trata-se de uma pesquisa qualitativa, de caráter exploratório, desenvolvida com professores de matemática do Ensino Fundamental II (do 6º ao 9º ano) de escolas públicas. A escolha do software Criba de Eratóstenes considerou seu acesso online e sua gratuidade. As estratégias foram desenvolvidas de forma sequencial, padronizada e detalhada para que o professor e o aluno tenham um roteiro de orientação durante a aula, bem como um auxílio na utilização do software.

Authors: Jungbluth Adriana , Silveira Everaldo , Grando Regina Célia
Published: May 2022

Neste artigo apresenta-se o resultado de um estudo que buscou investigar conhecimentos de professores dos anos iniciais do Ensino Fundamental sobre Álgebra e seu ensino. A Álgebra é uma das cinco unidades temáticas da Matemática para os anos iniciais, proposta na Base Nacional Comum Curricular (2017), cujo intuito é desenvolver o pensamento algébrico dos alunos. Como base de dados, utilizaram-se questionários respondidos por 98 professores e aprofundaram-se os dados através de entrevistas. A metodologia utilizada para análise de dados é a Grounded Theory – Teoria Fundamentada nos Dados. Os resultados obtidos apontam a ausência de formação específica para o ensino da unidade temática Álgebra, relatada por 74,5% dos professores, condição que os leva a não se sentirem preparados em seus conhecimentos para desenvolver atividades algébricas. Após diagnóstico inicial, passou-se às entrevistas reflexivas/formativas, realizadas com três duplas de professores, nas quais se enfatizaram dimensões da Álgebra proposta na BNCC para os Anos Iniciais, como a generalização de padrões em sequências e o sentido de equivalência da igualdade. Inicialmente, os professores não demonstraram clareza no conhecimento do conteúdo e do currículo, em aspectos como a relação entre o trabalho com as sequências e a generalização, a importância de trabalhar com o sentido de equivalência da igualdade e o uso do pensamento relacional. Durante as entrevistas reflexivas/formativas, os professores ressaltaram a importância do conhecimento e a necessidade de formação sobre os temas que contribuem para o desenvolvimento do pensamento algébrico, para que possam implementar o ensino da Álgebra, destacando a viabilidade desse ensino.

Authors: Oliveira Adriana Nogueira de , Pereira Ana Carolina Costa , Reges Maria Auricélia Gadelha
Published: May 2022

A Matemática desempenha papel importante na sociedade por fomentar a formação profissional a partir do desenvolvimento do pensamento abstrato, além de mobilizar conhecimentos exigidos no trabalho e nas relações sociais. Contudo, o ensino de Matemática tem levado alunos e professores a enfrentarem dificuldades provocadas pela necessidade de repensar a formação dos educadores para lecionarem essa disciplina. À vista disso, são crescentes os esforços por inovações no ensino de conteúdos matemáticos, em que se percebe a Teoria dos Campos Conceituais, que vem dando suporte a práticas pedagógicas que visam ao ensino de conteúdos matemáticos, como, por exemplo, o Campo Conceitual Aditivo. Essa concepção incorpora problemas de adição e de subtração, que podem ser classificados de acordo com o grau de dificuldade que apresentam. Assim, o presente artigo tem como principal objetivo discutir as situações-problema do Campo Aditivo, envolvidas na classe das extensões, elaboradas por um grupo de estudantes da licenciatura em Pedagogia. Trata-se de um recorte oriundo da investigação realizada dentro de uma pesquisa de mestrado em Educação. Dessa forma, o estudo situa-se na abordagem qualitativa, tendo como método a pesquisa-ação. Os resultados obtidos apontam que as discentes do curso de Pedagogia apresentam algumas dificuldades em elaborar situações-problema que envolvam raciocínio mais sofisticado. Com isso, é possível concluir que há a necessidade de fundamentação teórica sobre o Campo Aditivo na formação inicial de professores, uma vez que esta se mostra com potencial condicionante à aprendizagem dos conceitos matemáticos de adição e de subtração.
Electrical Energy Consumption In Agri-Food Establishments In West Cameroon
Authors: Mfewou Abdoulay , Nitcheu Vannelle Ngagoum , Umaru Hassan Buba
Published: May 2022

In the West Cameroon region, agri-food establishments: bakeries, fishmongers and restaurants contribute to three quarters (3/4) of employment in the towns, turnover and added value of regional businesses. These are also the sectors that consume the most electrical energy; between them, these establishments account for more than 50% of the electrical energy consumption in the entire Western region of the country. For six months, we conducted the study in (5the) major towns of West Cameroon chosen at random (Mifi, Menoua, Bamboutos, Nde and Haut-Nkam). Field observations of recurrent power cuts and surveys of local policy makers were also conducted on the supply of electricity, which remains problematic throughout the country. Our results show that the average electricity consumption per establishment is particularly high in bakeries, at around 1441.67 KWh, compared to 1295.45 KWh for fishmongers and 371.21 KWh for restaurants. Electricity is mainly used as a driving force for thermodynamic purposes (cold rooms, deep-freezing and air-conditioning of engines in bakeries, etc.). On the other hand, it should be noted that this sector of activity faces enormous difficulties, including the inadequacy of electrical energy in terms of supply, access and quality. The electricity supplied by The Energy of Cameroon (Eneo) is still very inadequate given the high demand. It is precarious and characterised by untimely power cuts. In fact, the average power cut in the cities studied is 24 days and 20 minutes, for a period of six months. We have come to the effective conclusion that recurrent power cuts are the result of a poor electricity supply and have a significant impact on the agri-food activity, due to their dependence on this source of energy. All these problems in West Cameroon indicate that energy demand will have to increase considerably in the coming years due to population growth (+7.8%) and socio-economic development. Therefore, we believe that policy makers should turn to renewable energies which are natural energy sources such as solar and wind power. In addition, local elected officials should think about building more mini hydroelectric dams in villages to reinforce urban areas with electrical energy.

Published: May 2022

Peruskoulun jälkeisen koulutuksen, harjoittelun tai työelämän ulkopuolella olevien suomalaisten nuorten aikuisten (ns. NEET-nuorten) ruokasuhteesta on niukasti tutkimustietoa. Tässä tutkimuksessa tavoitteena on tarkastella NEET-nuorten ruokasuhdetta hyödyntäen ruokasuhteen pedagogista viitekehystä. Siinä ruokasuhteen ajatellaan tulevan näkyväksi erityisesti dialogissa kohtaamisissa, joissa tutkittavat pääsevät itse kertomaan tutkijalle ruokasuhteestaan omista lähtökohdistaan käsin. Tutkimuksen aineisto koostuu kymmenen nuoren ruokasuhdehaastatteluista. Haastatteluaineistoa analysoitiin ensin narratiivisesti luomalla jokaiselle nuorelle oma ruokasuhteen tapauskertomus. Kertomuksia tarkasteltiin tämän jälkeen kokonaisuutena, josta muodostettiin nuorten ruokasuhteita jäsentäviä teemoja. Analyysin perusteella nuorten ruokasuhteen keskeisiä toiminnallisia ilmenemismuotoja ovat epäsäännöllinen ja niukka syöminen sekä ajoittainen ahmiminen, syöminen yksin kotona tai vain kaikkein lähimpien seurassa sekä valmiiden ja yksinkertaisten ruokien syöminen. Erilaiset henkilökohtaiset resurssivajeet, kuten rahan ja valmistusvälineiden puute, mielenterveyden ongelmiin kytkeytyvä voimattomuus ja turvattomuuden kokemus sekä heikko pystyvyyden tunne kytkeytyvät nuorten käytännön ruokatoimintaan. Nuorten ruokasuhdekertomuksista tunnistettiin kolme keskeistä merkityskokonaisuutta: ruoka pakollisena polttoaineena, ruoka kehon ja tunteiden muokkaajana, sekä ruoka itsen rankaisijana. Tyytymättömyys itseen ja omaan kehoon sekä halu joko kasvattaa tai erityisesti laihduttaa kehoa heijastui vahvasti nuorten ruokaan ja syömiseen liittämiin merkityksiin. Nuorten syömisen tarkastelu ruokasuhteen pedagogisen viitekehyksen avulla tuo esiin ruokasuhteen moniulotteisuuden ja sen monenlaiset fyysiseen, psyykkiseen ja sosiaaliseen hyvinvointiin liittyvät kytkennät, jotka pitäisi huomioida myös nuoria kohtaavissa palveluissa.

The aim of the work is to systematize current data on the peculiarities of the internal picture of the disease and the need for medical and psychological support of psychosomatic illnesses in children with different types of responses to the disease. The article is devoted to studying the internal picture of the condition as an integral part of the internal picture of health in pediatric practice. Types of patients' attitudes to the disease are considered. The types of disease responses from the standpoint of medical psychology are given. The typology of psychological response to the disease or personality types (harmonious, indifferent, hyperpathic, hypopathic, labile) in diseases of the gastrointestinal tract in children is described. Peculiarities of non-psychotic mental disorders in young children have been identified. It is noted that the development of differential programs of psychological support, taking into account the typology of psychological response to the disease, will accelerate the process of recovery and rehabilitation of patients. Conclusions. Increasing professional competence in an internal picture of the disease will improve communication links in the chain "health worker - sick child - parents". The timely organization of medical and psychological support at all levels of medical care for psychosomatic diseases in children will help prevent and reduce the incidence of neurotic and neurosis-like mental and behavioral disorders.

Published: May 2022

Objective. To study the effect of water load of negative redox potential with hydrogen saturation on renal function in comparison with induced diuresis with water of negative redox potential without hydrogen saturation.Material and methods. In experiments on 60 male white-nonlinear rats weighing 0.16-0.18 kg, the effect of loading with ordinary tap water (redox potential 90.4 ± 1.45 mV), water of negative redox potential without saturation with hydrogen (redox potential - 304.5 ± 4.79 mV) and water of negative redox potential with hydrogen saturation 1.0 - 1.2 ppm and redox potential -297.3 ± 5.27 mV. Used: experimental, physiological, biochemical, chemical, physicochemical, statistical research methods.Results. Under water load of negative redox potential with hydrogen saturation in comparison with induced diuresis of negative redox potential with the use of microhydrin, there was no inhibition of glomerular filtration, filtration fraction and proximal reabsorption of sodium ions, change restorative potential of urine. These changes are explained by the lack of activation of the dysregulatory mechanism of basal vascular tone of the renal cortex under conditions of water load of negative redox potential with hydrogen saturation.Conclusion. Water loading of negative redox potential with hydrogen saturation in comparison with induced diuresis of negative redox potential without hydrogen saturation causes recovery of glomerular filtration rate, filtration fraction and proximal reabsorption of sodium ions, due to the lack of activation of the mechanism of basal vascular tone of the renal cortical substance, due to the high permeability of molecular hydrogen and uniform delivery of electrons to all organs and tissues.

Peculiarities of morphofunctional changes of the wall of the small intestine in experimental animals during the development of streptozotocin diabetes mellitus, against the background of chronic immobilization stress and under the combined effects of these pathological conditions were studied. Objective – to evaluate the features of morphofunctional reconstruction of the small intestine of rats in experimental streptozotocin diabetes mellitus under chronic stress. Methods. Experimental adult rats were modeled for absolute insulin deficiency by intraperitoneal administration of streptozotocin at a dose of 7 mg per 100 grams of body weight. To simulate stress, the animals were subjected to daily rigid immobilization in special cages for 6 hours at different time intervals. In order to study the combined effects of these pathological factors, the animals were immobilized from the 14th day of diabetes mellitus. The material was taken 28 and 56 days after the start of the experiment. Results. During the development of experimental diabetes mellitus in the small intestinal wall of experimental animals, there is a predominance of enteropathy due to dystrophic changes in the intestinal wall. Focal signs of enteritis predominated during the 56-day simulation of chronic stress. With the combined effect of these pathological conditions on the 28th day of the experiment, focal signs of enteritis and enteropathy were observed, which progressed to 56 days of the experiment.Conclusions. On samples from the small intestine wall, stained with hematoxylin and eosin, in rats with experimental diabetes mellitus, mucosal atrophy was noted, which was manifested by shortening of the villi and an increase in the depth of the crypts. Against the background of chronic stress on the 28th day, the wall of the small intestine retained the normal histologic structure, with local signs of inflammation, but on the 56th day, there was significant leukocyte infiltration of the mucous membrane and submucosal layer, increased eosinophils, lymphocytes and histiocytes. In rats with diabetes on the background of stress, structural changes in the intestinal wall were characterized by the greatest polymorphism.

Authors: Wijaya Kristian Florensio , Mbato Concilianus Laos
Published: May 2022

It is decent to be purported here that the continual and precise internalization of metacognitive strategies in Indonesian EFL reading contexts will bring about positive influential impacts for L2 readers’ cognitive and affective reading development. Highly metacognitive L2 readers generally experience more stress-free and meaningful reading learning enterprises since they have become more critical, self-regulated, independent, and adaptable readers who are resistant to exacting reading learning challenges. This present qualitative study employed a document analysis approach to strongly encourage Indonesian EFL educationalists to steadily implement metacognitive strategies in their multivariate reading classroom vicinities. The obtained results uncovered that metacognitive reading strategies progressively transfigured Indonesian EFL learners into more self-regulated and autonomous L2 readers longing to inherent life-long second language learning spirit on their daily basis as academicians.
Issues in the Utilization of Transposition: A Case Study of The 100: A Ranking of the Most Influential Persons in History
Authors: A  Alharthi Adel Awadh
Published: May 2022

The current study aims to explore the types of transposition techniques used by Arab translators when translating The 100: A Ranking of the Most Influential Persons in History by Michael H. Hart (1978) into Arabic. The study seeks to address the following questions: a) what are the types of transposition/class shift used by Arab translators to translate the ST into Arabic; b) what are the factors that govern the translators’ utilization of transposition; and c) to what extent do the Arabic translations differ from the ST. The research draws on Vinay and Darbelnet (1995), Newmark (1988), and Catford 1965/2000. A qualitative approach was followed in this study. The qualitative approach involved identifying each instance of transposition, using a comparative model which is commonly used in translation studies to study shifts. The findings of the study revealed that the Arab translators used four types of transposition: noun to verb, adjective to verb, verb to noun, and adjective to noun. A possible explanation for the utilization of these techniques might be that the Arab translators had some stylistic preferences, which were evident in their different treatment of the linguistic elements in the source text. In addition, the translators worked within some linguistic constraints, which forced them to use various interventional strategies in order to bridge the linguistic gap between English and Arabic. The results of the study should add to previous research on transposition techniques and the factors that may affect their utilization in different contexts. Further research in this area is needed for more understanding of how transposition techniques may bridge the linguistic gap between the ST and TT.

Published: May 2022

In this paper, we study the relationship between marketwide liquidity and options market. Using the Chicago Board Options Exchange (CBOE) Volatility Index, VIX as a measure of overall value of the S&P 500 (SPX) options, and the CBOE SKEW Index as a measure of market crash risk premium in the options market, we study the relation among marketwide liquidity, VIX and SKEW. Empirical results show that higher the marketwide liquidity, less expensive the options and the less likely options traders anticipate a market crash.
LIQUIDITY OF FUTURES MARKETS OVER THE LAST QUARTER OF A CENTURY: TECHNOLOGY & MARKET STRUCTURE VERSUS ECONOMIC INFLUENCES

Published: May 2022

This study examines the major technological and market forces that have acted on the liquidity of futures markets over almost the last quarter of a century – equivalent to Professor Robert Webb’s tenor as Editor-in-Chief at the Journal of Futures Markets. We examine the impact of electronic trading replacing open outcry, the impact of high-frequency trading and co-located trading, compare the liquidity impacts of these developments with the impact of major economic events, including the Global Financial Crisis and Covid-19 Pandemic. Using a stock index futures contract traded on Australian futures exchanges as an example, we find that technological advances have had a statistically significant but almost imperceptible influence on measures of liquidity of Australian futures contracts. In contrast, economic crises, and crashes such as the Global Financial Crash and the Covid-19 crash have had a massive and sustained impact on the liquidity of futures markets. Our results suggest that liquidity effects from technological innovations, while important, remain dwarfed by those from extreme outlier events.
