Authors: Baldo Karina , Silva Larissa Da , Skoniesk Calinca , Benvegnú Dalila Moter
Published: July 2021

Introdução: A obesidade é um dos maiores problemas de saúde pública no mundo. A prática de atividade física e a mudança de hábitos são recomendadas no manejo dessa condição. A yoga popularizou-se como um exercício alternativo e a perda de peso e melhora do perfil lipídico são apontados em estudos como benefícios dessa prática. Objetivos: O objetivo desta revisão sistemática, foi avaliar se a prática de yoga gera benefícios para indivíduos portadores de sobrepeso e obesidade. Materiais e Métodos: Foram utilizados estudos publicados entre os anos de 2012 a 2018. Os termos de busca foram “Yoga” e “Obesity”, nas bases de dados Scopus, Medline, ScienceDirect e Pubmed, seguindo as diretrizes PRISMA. Foram selecionados estudos randomizados controlados ou antes-depois que aplicaram uma intervenção com prática de yoga em indivíduos com sobrepeso e/ou obesidade. Resultados: Dos 38 estudos selecionados, apenas 9 foram inclusos nesta revisão, sendo que 15 foram excluídos por serem duplicados, 04 por incluirem individuos eutróficos, 3 por se tratar de revisão de literatura e 01 abordava apenas sobrepeso. A amostra variou entre 16 a 279 participantes e a idade média de 36 a 55 anos com uma população homogênea. A intervenção foi heterogênea, em relação à duração do estudo, frequência e duração das aulas. Todos os estudos evidenciaram efeito positivo da prática de yoga na perda de peso e no índice de massa corporal, em ambas situações, independentemente do protocolo aplicado. Entre os 9 estudos, 7 deles avaliaram desfechos secundários, sendo que em 3 estudos houve redução significativa nos parâmetros de glicemia e 4 estudos mostraram significativa diminuição no colesterol total. Conclusão: A revisão sistemática mostrou que a yoga é uma prática de atividade física promissora para portadores de sobrepeso e obesidade, pois além de contribuir para a perda de peso, favoreceu a diminuição nos parâmetros clínicos, como perfil glicídico e lipídico.

Published: July 2021

Introdução: O glutamato monossódico (MSG) é um aditivo colocado durante o preparo dos alimentos para potencializar o sabor. Entretanto, o seu consumo em excesso (>2%) pode ocasionar tonturas, cefaléia e dores nos membros 20 minutos após a ingestão. Além disso, os efeitos adversos são mais perceptíveis no sexo feminino em relação ao masculino e se o MSG for consumido após o jejum e dissociado de alimentos. Objetivo: Investigar os efeitos da ingesta de MSG no organismo humano. Materiais e Métodos: Foi realizada uma revisão sistemática de literatura, analisando estudos publicados na base de dados PubMed. A frase de pesquisa foi construída mediante consulta ao MeSH com os descritores: Glutamato monossódico, Enxaqueca e Cefaleia. Resultados: O MSG é capaz de alterar o sabor dos alimentos, já que tende a ser menos palatável. Em relação à dor, é dito que o MSG torna os músculos da mastigação e outros músculos esqueléticos mais sensibilizados e está mais concentrado em regiões dolorosas no músculo, causando diversos tipos de dores, como a craniofacial, além das cefaleias. O MSG desencadeia a liberação de óxido nítrico, que provoca a dilatação de vasos sanguíneos intracranianos e extracranianos, desencadeando a cefaleia. Sabe-se que o MSG está relacionado com toxicidades, como disfunções metabólicas, efeitos neurotóxicos, comprometimento dos órgãos reprodutivos, danos hepáticos, perturbação na fisiologia do tecido adiposo e obesidade. Ademais, o glutamato pode ser encontrado na sua forma natural em alimentos como peixes, tomates, queijos. Tanto glutamato natural, quanto MSG são metabolizados da mesma forma, uma vez que o glutamato é uma proteína importante. O consumo de MSG é vantajoso por reduzir a ingesta de cloreto de sódio, o que ajuda pacientes que necessitam de dietas hipossódica. Porém tal substituição não é totalmente vantajosa, já que o MSG pode causar elevação da pressão arterial e da frequência cardíaca. Conclusão: O MSG potente aditivo na culinária, é encontrado em fast food e em temperos prontos. Ele é um estimulador para desencadear ou agravar dores de cabeça, que possuem efeitos mais frequentes nas mulheres, bem como para causar alterações na pressão arterial. Os sintomas são cefaleias, dormências, distúrbios gastrointestinais, tonturas, vómitos.

Published: July 2021

Introdução: A neurocisticercose (NCC) consiste numa infecção ocasionada pela forma cística da tênia do porco, o helminto Taenia solium, cujos cisticercos (forma larval) podem se alojar em qualquer área do sistema nervoso central (SNC) do ser humano, levando a forma mais grave do complexo teníase/cisticercose, que está entre as principais doenças tropicais negligenciadas (DTN). Além da natureza multifatorial, a NCC se dissemina principalmente por meio da ingestão acidental de ovos do parasita em alimentos e água contaminados, além da autoinfecção em portadores da teníase. Logo, esse conjunto de fatores transforma a NCC em uma séria questão de saúde coletiva. Objetivos: Analisar o desenvolvimento das manifestações clínicas em pacientes diagnosticados com neurocisticercose em decorrência de infecção pela forma cística do parasita T. solium. Material e Métodos: Através da análise bibliográfica da literatura disponível, artigos publicados entre dezembro de 2010 e fevereiro de 2020 foram selecionados, utilizando as plataformas PUBMED, WEB OF SCIENCE, SCIELO e PERIÓDICOS CAPES como bases de dados, aplicando os descritores “Neurocisticercose”, “Taenia solium”, em inglês e português, operando critérios de inclusão e exclusão para seleção dos artigos utilizados. Resultados: A NCC desenvolve-se após a ingestão de ovos de T. solium, que em seguida eclodem e originam oncosferas (estágio larval) capazes de penetrar na parede intestinal. Logo após, os parasitos caem na corrente sanguínea, podendo a atingir vários órgãos distintos, assumindo assim a forma de cisticercos. Contudo, quando esse parasito alcança o SNC, a forma de cisticerco vesicular é mantida por um período de tempo que pode chegar a anos, o que leva a quadros inflamatórios discretos pelo mesmo intervalo temporal. Caso em um segundo momento uma resposta imune seja desencadeada, o cisticerco degenera-se e os sinais e sintomas da NCC manifestam-se, como convulsões e aumento da pressão intracraniana. Conclusão: A NCC consiste em uma condição parasitária multifatorial, resultante da infecção pela T. solium, a qual, em sua forma larvária, é responsável por desencadear diferentes apresentações clínicas severas. Em virtude disso, faz-se necessário ações da prevenção primária a terciária para prevenir e combater o avanço dos casos de NCC, bem como de outras teníases.

Introdução: Mesoterapia com deoxicolato de sódio (DEOXI) é um procedimento minimamente invasivo utilizado para contorno corporal. No Brasil, a Agência Nacional de Vigilância Sanitária (ANVISA) proibiu o uso para este fim, mas ainda é utilizado na redução da gordura subcutânea, mesmo sem estudos sobre a segurança. Objetivo: Avaliar o efeito crônico do DEOXI sobre massa corporal e perfil metabólico em camundongos. Material e métodos: CEUA 1011/2017. Camundongos suissos fêmeas (3 meses) receberam água (C) ou frutose 20% (F) ad libitum por 8 semanas, seguido de 8 aplicações subcutâneas (região inguinal direita) de 100µL salina ou DEOXI 50µg 2x/semana (grupos C/Sal n=7; C/Deoxi n=7; F/Sal n=6 e; F/Deoxi n=6). Analisou-se a massa corporal (MC), glicemia, intolerância à glicose (TOTG), resistência à insulina (IPITT), massa adiposa e hepática, colesterol total (CT) e triglicerídeo (TG) sanguíneo. Dados em média±DP, 2-way ANOVA, pós teste de Tukey, p<0,05 (GraphPad Prism 6.0). Resultados: A análise macroscópica mostrou nódulos fibróticos na gordura inguinal (GI) direita, conforme descrito em humanos. Não houve diferença na MC entre os grupos C e F após 8 semanas (antes das aplicações). As aplicações de DEOXI também não alteraram a MC após 4 semanas. Nos depósitos de tecido adiposo, notou-se um maior peso da gordura genital (GG) no grupo F/Deoxi vs. C/Sal (p<0,05), mas sem diferença entre os grupos na GI direita ou na relação GI/GG. Ingestão de frutose por 8 ou 12 semanas não alterou a glicemia, nem provocou intolerância à glicose ou resistência à insulina (RI) no grupo F/Sal. Também não houve alteração nesses parâmetros nos grupos C/Deoxi e F/Deoxi após 8 aplicações, exceto a RI no grupo C/Deoxi vs. C/Sal (p<0,01). O CT e o TG não se alteraram entre os grupos, assim como o peso hepático. Conclusão: Os dados preliminares não mostraram efeito adverso expressivo sobre o metabolismo de nenhum grupo e a dose escolhida não reduziu a gordura subcutânea no local da aplicação como esperado, porém, foram observados nódulos no local, mostrando a necessidade de mais estudos.

icepack: a new glacier flow modeling package in Python, version 1.0
Authors: Shapero Daniel R. , Badgeley Jessica A. , Hoffman Andrew O. , Joughin Ian R.
Published: July 2021

Abstract. We introduce a new software package called “icepack” for modeling the flow of glaciers and ice sheets.
The icepack package is built on the finite element modeling library Firedrake, which uses the Unified Form Language (UFL), a domain-specific language embedded into Python for describing weak forms of partial differential equations.
The diagnostic models in icepack are formulated through action principles that are specified in UFL.
The components of each action functional can be substituted for different forms of the user's choosing, which makes it easy to experiment with the model physics.
The action functional itself can be used to define a solver convergence criterion that is independent of the mesh and requires little tuning on the part of the user. The
icepack package includes the 2D shallow ice and shallow stream models.
We have also defined a 3D hybrid model based on spectral semi-discretization of the Blatter–Pattyn equations.
Finally, icepack includes a Gauss–Newton solver for inverse problems that runs substantially faster than the Broyden–Fletcher–Goldfarb–Shanno (BFGS) method often used in the glaciological literature.
The overall design philosophy of icepack is to be as usable as possible for a wide a swath of the glaciological community, including both experts and novices in computational science.
GREB-ISM v0.3: A coupled ice sheet model for the Global Resolved Energy Balance model for global simulations on time-scales of 100 kyr

Published: July 2021

Abstract. We introduce a newly developed global ice sheet model coupled to the Globally Resolved Energy Balance (GREB) climate model for the simulation of global ice sheet evolution on time scales of 100 kyr or longer (GREB-ISM v0.3). Ice sheets and ice shelves are simulated on a global grid, fully interacting with the climate simulation of surface temperature, precipitation, albedo, land-sea mask, topography and sea level. Thus, it is a fully coupled atmosphere, ocean, land and ice sheet model. We test the model in ice sheet stand-alone and fully coupled simulations. The ice sheet model dynamics behave similarly to other hybrid SIA (Shallow Ice Approximation) and SSA (Shallow Shelf Approximation) models, but the West Antarctic Ice Sheet accumulates too much ice using present-day boundary conditions. The coupled model simulations produce global equilibrium ice sheet volumes and calving rates similar to observed for present day boundary conditions. We designed a series of idealised experiments driven by oscillating solar radiation forcing on periods of 20 kyr, 50 kyr and 100 kyr in the Northern Hemisphere. These simulations show clear interactions between the climate system and ice sheets, resulting in slow build-up and fast decay of ice-covered areas and global ice volume. The results also show that Northern Hemisphere ice sheets respond more strongly to time scales longer than 100 kyr. The coupling to the atmosphere and sea level leads to climate interactions between the Northern and Southern Hemispheres. The model can run global simulations of 100 kyr per day on a desktop computer, allowing the simulation of the whole Quaternary period (2.6 Myrs) within one month.

Published: July 2021

Abstract. The detection of flammable gases is necessary to avoid explosive atmospheres. For this reason, low-cost pellistors are frequently used. However, such commercial pellistors require an operation temperature of 450 ∘C or more for the detection of methane and a correspondingly high power consumption. We present a novel wireless low-power catalytic gas sensor system based on non-precious metal catalyst for the detection of methane and propane operated at 350 ∘C. The combination of a microelectromechanical system (MEMS)-based sensor with a low-power radio system provides the opportunity to monitor complex infrastructure without using a power grid as power supply. The sensor system has been characterised extensively under the exposure to methane and propane at concentrations between 2000 and 8000 ppm, as these gases are the common test gases for pellistors in industry. Methane is the main component of natural gas; propane is an important component of liquified petroleum gas (LPG). In addition, the influence of changes in humidity on the sensor response to methane was examined in more detail. Due to the planned operation of the sensor and radio system in different application scenarios, short (3 s) and long (60 s) sampling rates were used for investigations.

Abstract. Tropical cyclones (TCs) in the Bay of Bengal can be extremely destructive when they make landfall in India and Bangladesh. Accurate prediction of their track and intensity is essential for disaster management. This study evaluates simulations of Bay of Bengal TCs using a regional convection-permitting atmosphere-ocean coupled model. The Met Office Unified Model atmosphere-only configuration (4.4 km horizontal grid spacing) is compared with a configuration coupled to a three-dimensional dynamical ocean model (2.2 km horizontal grid spacing). Simulations of six TCs from 2016–2019 show that both configurations produce accurate TC tracks for lead times of up to 6 days before landfall. Both configurations underestimate high wind speeds and high rain rates, and overestimate low wind speeds and low rain rates. The ocean-coupled configuration improves landfall timing predictions and reduces wind speed biases relative to observations outside the eyewall but underestimates maximum wind speeds in the eyewall for the most intense TCs. The coupled configuration produces weaker TCs than the atmosphere-only configuration, consistent with lower sea surface temperatures in the coupled model and an overestimated cooling response in TC wakes. Both model configurations accurately predict rain rate asymmetry, suggesting a good representation of TC dynamics. Much of the rain rate asymmetry variation in the simulations is related to wind shear variations, with a preference for higher rain rates in the down-shear left quadrant.
Effectively using multifidelity optimization for wind turbine design
Authors: Jasa John , Bortolotti Pietro , Zalkind Daniel , Barter Garrett
Published: July 2021

Abstract. Wind turbines are complex multidisciplinary systems that are challenging to design because of the tightly coupled interactions between different subsystems. Computational modeling attempts to resolve these couplings so we can efficiently explore new wind turbine systems early in the design process. Low-fidelity models are computationally efficient but make assumptions and simplifications that limit the accuracy of design studies, whereas high-fidelity models capture more of the actual physics but with increased computational cost. This paper details the use of multifidelity methods for optimizing wind turbine designs by using information from both low- and high-fidelity models to find an optimal solution at reduced cost. Specifically, a trust-region approach is used with a novel corrective function built from a nonlinear surrogate model. We find that for a diverse set of design problems—with examples given in rotor blade geometry design, wind turbine controller design, and wind power plant layout optimization—the multifidelity method finds the optimal design using 38 %–58 % the computational cost of the high-fidelity-only optimization. The success of the multifidelity method in disparate applications suggests that it could be more broadly applied to other wind energy or otherwise generic applications.
Influence of Wind Turbine Design Parameters on Linearized Physics-Based Models in OpenFAST

Published: July 2021

Abstract. While most physics involved in wind energy are nonlinear, linearization of the underlying nonlinear wind-system equations is often important for understanding the system response and exploiting well-established methods and tools for analyzing linear systems. Linearized models are important for, e.g., eigenanalysis (to derive structural natural frequencies, damping ratios, and mode shapes) and controls design (based on linear state-space models). In controls co-design (CCD), whose methods often rely on linearized time-domain models of the physics, the physical structure (often called the plant) and controller are designed and optimized concurrently, so, it is important to understand how changes to the physical design affect the linearized system. This work summarizes efforts done to understand the impact of design parameter variations in the physical system (mass, stiffness, geometry, etc.) on the linearized system using OpenFAST.

Published: July 2021

The objectives of this systematic review were to summarize and evaluate the effectiveness of strength and conditioning trainings on front crawl swimming, starts and turns performance with relevant biomechanical parameters. Four online databases including PudMed, ESCSOhost, Web of Science and SPORTDiscus were searched according to different combination of keywords. 954 articles were extracted from databases, and ultimately 15 articles were included in this study after removal of duplicate and articles screening according to inclusion and exclusion criteria. Meta-analyses were adopted when appropriate and Egger’s regression symmetry was adopted to assess the publication bias and the results were presented with forest plots and funnel plots respectively. Fifteen articles studied the effects of strength and resistance, core, and plyometric trainings. The quality of the investigation was assessed by the checklist developed by Downs and Black. Most of the investigations found out that training programs were beneficial to front crawl sprinting swimming performance, stroke biomechanics, force, and muscle strength. First, strength and resistance trainings and core trainings were effective on sprinting performance enhancement. Second, resistance trainings were found to have positive effects on stroke rate. Plyometric trainings were beneficial to start performance, while there was no sufficient evidence for confirming the positive improvement on turn biomechanical, also overall swimming performance, after weeks of plyometric trainings. Strength and Conditioning trainings are suggested to implement in regular training regime regarding to the positive effects on swimming performance, including starts, turns and front crawl swim, and relevant biomechanical parameters, instead of swimming training only. Further research with higher quality is recommended to conduct and more investigations on the training effects to other stroke styles are also suggested.

Coach workshops based on seven principles (inspiration, explanation, expectation, support, reward, appreciation, growth and winning) enhance the sport experience of adult athletes. Therefore, we have investigated the effects of such workshops with coaches of child athletes. Study participants were coaches of 57 9- to 12-year old girls (practicing gymnastics) and boys (practicing football). Three coaches of 28 children attended three workshops over 12 weeks, while a control group of 5 coaches of 29 children attended no workshops. Measures of well-being and psychomotor performance were taken on the children before and after the intervention; differences in mean changes between intervention and control groups were adjusted for baseline, standardized, and assessed with a conservative magnitude-based decision method. There were clear substantial effects of the workshop on motivation averaged across several dimensions (girls, large, most likely beneficial), on a decision test (boys, small-moderate, very likely beneficial), on state anxiety self-reflection (girls, moderate, likely harmful), and on reaction time (boys, small, possibly harmful). The beneficial effects of the workshop in this pilot study are encouraging, but the unclear and potentially harmful effects and the roles of presenter- and coach-specific effects need to be investigated further with a representative sample of coaches and more children before the workshop is recommended for implementation.
USING A FUNCTION DERIVATIVE IN ECONOMIC TASKS
Authors: Lomtadze Maka
Published: July 2021

The article focuses on the application of mathematical methods in economics, in particular discussing economic problems that are easily solved using derivatives.
The purpose of the article is to show students the way and opportunity to use mathematical methods to solve economic problems. To this end, the article discusses and analyzes several economic tasks in detail, which will be interesting and easy for students to master.
I considered the derivative of a function as the rate of change and introduced the definition: The instantaneous rate of change of the function f with respect to x at a point is called the derivative if it exists. With the help of this definition I have discussed and explained
Task 1: Suppose that the increase in production of a certain product over a period of time is described by a function

And population growth is described by the following function:

Where is the number of years from the initial period, then the production of these products per capita is given by the function:

Find the growth rate of product production.
By solving this task I came to the conclusion that after a year the production of products per capita increases.
In the following tasks I used the method of finding the extremum values of a function using a derivative, namely I equated the first-order derivative to 0, found the critical points, and with the help of the second-order derivative I determined the extremes of the function.
I discussed task 2: For the production of X volume of products, the firm plans a cost that is calculated by the formulan . For what volume of production will the average cost be the smallest? Find the numerical value of this small expense.
Solving this problem, I came to the conclusion that the given function of the average cost takes on the least value when the output volume is a unit , and this value is equal to: which is the marginal cost when producing the volume output.
I discussed Task 3: How many products should be sold in order for a firm to profit maximally if the derivative cost function is known:

And return function:
Here I came to the conclusion: if 600 units of the product are sold, then the firm's profit will be maximum and it will be numerically equal
At the end of the article I discussed such a task 4 of applied optimization. What is the minimum amount of material needed to make a 2 liter cylindrical jar?
Where I came to the conclusion: the smallest amount of material will be spent to get a cylindrical vessel if we take the height 2 times the radius of the base.

Published: July 2021

Every university course is developed, taught and learned in the expectation that it will ultimately prove useful to the learner economically or in promoting personal understanding of, and adaptation to the natural and social environments of living and work relations. Management is no exception to this rule. However, because of the general ration that the course management is simple but scarily be sufficiently understood, let alone be made sufficiently relevant today –to – day life and work, the need exists for course lecturers in particular to be adequately equipped to negate these notions and to rather render the course understandable, enjoyable and useful. This paper provides some readily applicable working understandings of and applicative hints on the main branches of management. As an enrichment effort, the meaningful application of some selected information science, or information system – related tertiary level branches of management are also treated to pave the way for the more specially focused paper presentation.
