Some controversy remains regarding the effects of aquatic exercise on body weight and composition. The purpose of this study was to determine the short-term impacts of the WATERinMOTION aquatics exercise program on body weight and composition without nutritional intervention in sedentary older women with overweight/ obesity. The study was developed as a quasi-experimental project (pre/post-study). Forty-four inactive women were volunteers from a convenience sample with a mean age of 71.1±5.7 years (Ukraine, 2019). Participants were allocated randomly into two groups: WATERinMOTION (n=22) or a control group (n=22). Meanwhile, the WATERinMOTION group performed the WATERinMOTION exercise programme with two weekly sessions of 55 minutes each. The control subjects did not participate in any physical exercises. They were asked to perform their routine activities during the study. Both programmes lasted one month. Height, body weight, body mass index (BMI), waist circumference (WC), fat mass (FM), total body water (TBW), and free fat mass (FFM) were the anthropometric variables that were measured pre/post-study. The analysis found statistically significant differences in body weight (-0.7, P=0.004), BMI (-0.3, P=0.002), and FM (-0.6, P=0.03) between the pre and post measurements of the WATERinMOTION group. Moreover, the comparison of groups at post revealed a significant difference in body weight (P˂0.001), BMI (P˂0.001), TBW (P=0.005), FM (P˂0. 001), FFM (P=0.003), and WC (P=0.007). The WATERin- MOTION programme, which is not associated with nutritional monitoring, showed significant benefits for losing weight and the body composition of sedentary older women who are overweight and/or obese.

This study compares the effects of the uptake or inhalation of 50uL Mentha piperita (MP) essential oil for 10 days on heart rate variability (HRV) and cardiopulmonary regulation during various exercise intensities. Forty-eight healthy male subjects were randomly assigned to MP uptake (MPU; n=16), MP inhalation (MPI; n=16), and control group (C; n=16). All participants were measured resting HRV, respiratory, cardiovascular, and metabolic parameters during aerobic, anaero- bic, and graded exercise tests (GXT) before and after treatment. There were significant increases in the low-frequency area (LFa; 1.8±0.1 vs 2.2±0.2 ms²), the ratio of low frequency to respiration frequency area (LFa/RFa; 0.9±0.1 vs 1.3±0.1) at resting and carbon dioxide production (VCO 2 ; 41.2±4.0 vs 49.2±6.8 mL/min -1 /kg -1 ), ventilation per minute (V E ; 80.2±4.3 vs 97.5±5.5 L/min -1 ), and respiratory rate (RR; 38.2±1.9 to 44.3±2.1 breath/min -1 ) in an anaerobic test following MPU inter- vention. In GXT, maximal carbon dioxide production (VCO 2max; 51.9±3.5 to 59.1±6.4 mL/min -1 /kg -1 ), maximal ventilation per minute (V Emax ; 126.4±6.5 to 138.4±5.4 L/min -1 ) and maximal respiratory rate (RR max ; 52.7±3.6 to 60.1±2.3 breath/min -1 ) significantly increased in MPU. The correlations of ΔLFa with ΔVCO 2max , ΔV Emax , and ΔRR max in the MPU group were signifi- cant. Continuous uptake or inhalation of 50uL MP oil for 10 days does not improve aerobic capacity and maximal exercise performance, but 10 days’ uptake of MP essential oil increased sympathetic activity at rest and may relate to respiratory regulation under high-intensity exercise.

A representação do processo precipitação-vazão por meio de modelos hidrológicos conceituais visa quantificar o volume escoado em uma bacia como consequência de uma determinada precipitação. Aliados a eles, os índices têm sido uma ferramenta útil para quantificar eventos extremos, como o Soil Moisture Index (TMI) que foi formulado a partir do modelo hidrológico Tank Model. Desta forma, o objetivo deste trabalho foi aplicar o Tank Model para a bacia do rio Perdizes, em Cambará do Sul (RS), e avaliar o desempenho do TMI para prever a ocorrência de cheias, limiar este utilizado para o fechamento da Trilha do rio do Boi, no Parque Nacional de Aparados da Serra (PNAS). Os dados utilizados na simulação foram obtidos pelas estações meteorológica e fluviométrica instaladas na bacia. Após a calibração e validação de três séries históricas no Tank Model, os valores obtidos do TMI foram comparados com os dias que a Trilha foi fechada, a partir de altos níveis registrados no rio Perdizes. O TMI demonstrou que o nível utilizado para fechar a Trilha do rio do Boi correspondeu a cheias em 72% das vezes. Portanto, o TMI mostrou bom desempenho ao indicar a ocorrência de cheias na área estudada, sendo uma ferramenta útil para a tomada de decisões na gestão do PNAS.  Application of the Tank Model as a Management Tool in the Perdizes River Basin - Cambará do Sul/RS.ABSTRACTThe representation of the rainfall-runoff process by means of conceptual hydrological models aims to quantify the volume drained in a basin as result of a specific precipitation. Allied to them, the indices have been a useful tool to quantify extreme events, such as the Tank Moisture Index (TMI) which was formulated from the Tank Model. Thus, the objective of this work was to apply the Tank Model to the Perdizes river basin, in Cambará do Sul (RS), and to evaluate the performance of the TMI to predict the occurrence of floods, the threshold used for the closure of the Rio do Boi trail, in the Aparados da Serra National Park (PNAS). The data used in the simulation were obtained at the meteorological and fluviometric stations installed in the basin. After the calibration and validation of three historical series in the Tank Model, the values obtained in the TMI were compared with the days when the Trail was closed, from high levels recorded in the Perdizes river. The average TMI values demonstrated that the level used to close the Rio do Boi Trail corresponded to floods 72% of the time, and the median, 75%. Therefore, the TMI showed good performance in indicating the occurrence of floods in the study area, being a useful tool for decision making in the PNAS management.Keywords: Tank Moisture Index, trail closure, Aparados da Serra National Park.

Authors: Silva Wanda Tathyana De castro , Segundo Georgenes Hilario Cavalcante
Published: July 2021

O conforto térmico, Humidex, é uma variável muito importante para avaliar o grau de estresse térmico em seres vivos. Por depender de variáveis climáticas, o Humidex tem uma variação espaço-tempo-intensidade condicionada a vários atenuadores do tempo e do clima. Assim, o objetivo deste trabalho é verificar possíveis tendências e análises espaço-temporais do índice Humidex no Nordeste do Brasil (NEB). Foram utilizados os dados do ERA5 distribuídos pelo ECMWF para o período de 1990 a 2019. Constatou-se que a região do MATOPIBA foi a que mais se destacou com tendências positivas de desconforto sobre o NEB, assim como a região com os maiores índices Humidex. Enquanto na costa do NEB havia vales baixos de Humidex que podem estar associados à influência oceânica. Observou-se que o período noturno tem tendência positiva no NEB, principalmente no MATOPIBA. Além da escala horária, constatou-se também que na escala mensal, sazonal e anual, esta região do MATOPIBA tem destaque. Isso se deve ao fato da substituição da floresta natural pela produção agrícola, na qual, afeta diretamente o balanço energético desta região. A região de MATOPIBA apresentou as maiores tendências de temperatura em NEB com taxa positiva variando de + 0,008ºC / Hora / Mês a 0,01ºC / Hora / Mês. A tendência sazonal de umidade foi marginal apenas na região costeira, com poucas áreas com valores máximos de 0,01 ºC / ano a 0,02 ºC / ano. Aproximadamente 2,41% do NEB apresenta tendência igual ou superior a +0,06 ºC / Ano e 24,21% do NEB com tendência igual ou superior a + 0,05 ºC / Ano.

Nesse estudo foi aplicada uma metodologia de classificação dos eventos de El Niño em seus diferentes tipos (Central, Leste e, quando ambos ocorrem concomitantemente, MIX) no período de janeiro de 1950 a março de 2019. Além disso, os tipos de El Niño foram separados por estação do ano e considerando as diferentes condições de anomalias de temperatura da superfície do mar no oceano Atlântico Tropical Sul (neutras quando ocorrem anomalias de temperatura entre -0,5º e 0,5ºC; quentes quando as anomalias são superiores a 0,5ºC e frias quando as anomalias são inferiores a -0,5ºC). Com base nas combinações de ocorrência de cada tipo de EN e anomalias de temperatura da superfície do mar no Atlântico Tropical Sul, foram determinadas as anomalias de precipitação na América do Sul. Os diferentes tipos de El Niño são mais frequentes quando há condições neutras no Atlântico Tropical Sul. Com relação às anomalias de precipitação na América do Sul, os eventos de El Niño Leste e MIX, em geral, mostram padrão similar na distribuição espacial das anomalias, mas com os eventos MIX mostrando sinal mais fraco. As anomalias de temperatura da superfície do mar no Atlântico Tropical Sul quando negativas ajudam a fortalecer as condições secas entre o norte das regiões norte e nordeste do Brasil propiciadas pelos eventos de El Niño.  Influence of the Different Types of El Niño in the Precipitation over South America  A B S T R A C TIn this study, a specific methodology was applied to classify El Niño events into their different types (Central, East and when both occur at the same time, MIX) from January 1950 to March 2019. In addition, the types of El Niño were separated by season and considering the conditions of sea surface temperature anomalies on the South Tropical Atlantic Ocean (neutrality: temperature anomalies between -0.5º and 0.5ºC, warm: anomalies above 0.5ºC and cold:  anomalies below -0.5ºC). Based on in the combination of different types of El Niño and sea surface temperature anomalies on the South Atlantic Tropical Ocean, precipitation anomalies over South America were computed. The different types El Niño occur, in general, under neutral conditions on the Atlantic Ocean. The events of El Niño - East and MIX, in general, present a similar pattern in the spatial distribution of the precipitation anomalies over South America, but with the MIX events showing weaker signal. Sea surface temperature anomalies in the Tropical South Atlantic when negative, they help to strengthen the dry conditions between the north of the north and northeast regions of Brazil caused by the El Niño events.Keywords: atmospheric circulation, anomaly conditions, tropical oceans, climate

A degradação ambiental de uma bacia hidrográfica pode ser resultado de uma série de ações geradas pela atividade antrópica, podendo ser analisadas de forma sistêmica através do diagnóstico físico conservacionista, para diagnosticar os impactos ambientais negativos e ajudar no planejamento ambiental das bacias hidrográficas. Neste trabalho foi aplicada a metodologia do Diagnóstico físico conservacionista (DFC) na bacia hidrográfica do Rio Judia, localizada em Rio Branco – Acre. Para isso, os parâmetros foram adaptados para a realidade local, sendo aplicados por meio de técnicas de geoprocessamento, a fim de identificar e quantificar o grau de degradação da bacia hidrográfica entre os anos de 2006 à 2019. Os resultados apontaram que, o médio curso obteve o maior grau de degradação, 23. O baixo curso obteve valor 22 e o auto curso valor 21. Todos os três cursos da bacia hidrográfica tiveram valores elevados de degradação, indicando que recursos naturais como solo, floresta e água encontram-se ameaçados por atividades antrópicas como: pecuária, uso indiscriminado da água e ocupações irregulares. Conclui-se que a metodologia do DFC possibilitou a correta identificação quanto ao grau de degradação da bacia do Rio Judia, apontando os parâmetros que mais contribuíram para o atual cenário ambiental. Physical Conservationist Diagnosis (PCD) as a methodology for quantifying environmental degradation in the Rio Judia river basin - Acre A B S T R A C TThe environmental degradation of a hydrographic basin can be the result of a series of actions generated by anthropic activity, which can be analyzed in a systemic way through the physical conservationist diagnosis, to diagnose the negative environmental impacts and help in the environmental planning of the hydrographic basins. In this work, the methodology of physical conservationist diagnosis (PCD) was applied in the Judia River basin, located in Rio Branco - Acre. For this, the parameters were adapted to the local reality, being applied through geoprocessing techniques, in order to identify and quantify the degree of degradation of the watershed between 2006 and 2019. The results showed that the mean course obtained the highest degree of degradation, 23. The low course obtained value 22 and the auto course value 21. All three courses of the watershed had high degradation values, indicating that natural resources such as soil, forest and water are threatened by anthropic activities such as livestock, indiscriminate use of water and irregular occupations. It was concluded that the PCD methodology allowed the correct identification of the degree of degradation of the Judia River basin, pointing out the parameters that most contributed to the current environmental scenario.Keywords: degree and degradation, environment, hydrographic Basin

O conhecimento das características físicas de sedimentos transportados por grandes sistemas fluviais possui significativa importância para o entendimento de processos geomorfológicos e hidrológicos. O nível de conhecimento dos grandes sistemas fluviais da Amazônia e sua relação com o transporte de sedimentos ainda é limitado, resultando em lacunas de conhecimento sobre a dinâmica da paisagem nesta complexa região. Este trabalho teve como objetivo avaliar a distribuição espacial da granulometria de sedimentos de fundo e suspenso do Rio Negro e tributários. Realizou-se análise da distribuição do tamanho dos sedimentos em seções amostrais localizadas no alto, médio e baixo curso do Rio Negro. Os resultados da análise granulométrica da carga de fundo indicam a predominância de sedimentos com tamanho variando de 0,25 a 1,0 mm (principalmente areia fina, areia média e areia grossa) enquanto no baixo curso as amostram oscilaram de areia fina a partículas lamosas (< 0,50 mm). No Rio Negro os sedimentos suspensos são compostos principalmente de partículas finas de silte (90% menor que 80 µm) com diâmetro mediano (D50) de 25 µm. As características granulométricas apresentadas neste trabalho fornecem subsídios para o entendimento de processos hidrodinâmicos de transporte e deposição dos sedimentos de fundo e suspenso neste gigante sistema fluvial.    Upstream-downstream Granulometry Analysis of bed and suspended sediments in the Negro River Basin (Amazon Basin, Brazil)A B S T R A C TThe knowledge of the physical characteristics of sediments transported by large river systems has significant importance for the understanding of geomorphological and hydrological processes. The level of knowledge of the large rivers of the Amazon basin and their relationship with sediment transport is limited, resulting in gaps about the dynamics of the landscape in this complex region. This article analyzes the spatial distribution of granulometry of bed and suspended sediments in the Negro River and tributaries. An analysis of the sediment size distribution was carried out in sample sections located in the upper, middle and lower reaches of the Negro River. The results of the granulometric analysis of the bed load indicate the predominance of sediments with sizes ranging from 0.25 to 1.0 mm (mainly fine sand, medium sand and coarse sand) while in the low course they showed oscillated from fine sand to muddy particles (<0.50 mm). In the Negro River basin the suspended sediments are composed mainly of fine silt particles (90% less than 80 µm) with a median diameter (D50) of 25 µm. The granulometric characteristics presented in this work provide subsidies for the understanding of hydrodynamic processes of transport and deposition of bed and suspended sediments in this huge fluvial system.Keywords: sediment transport, Amazon floodplain, multichannel river, anabranching

Совершенные стехиометрические монокристаллы Pb5Ge3O11 подвергнуты радиационному облучению g-квантами 60Co (1·106 Рад) и высокоэнергетическими электронами (0.13, 0.89, 2.18, 3.07·1018 э/cм2) в НИФХИ им. Л.Я. Карпова. прослежено изменение структурных и сегнетоэлектрических свойств кристаллов в зависимости от типа и дозы облучения. Методы диэлектрической спектроскопии и генерации второй гармоники лазерного излучения использованы для определения температуры сегнетоэлектрического фазового перехода TС. Рентгенодифракционные эксперименты проведены на дифрактометре Bruker D8 QUEST с детектором PHOTON-II (MoKα излучение, 295 K). По экспериментальным структурным амплитудам расшифрована и уточнена кристаллическая структура кристаллов до и после облучения. Структурные характеристики необлученного кристалла находятся в удовлетворительном согласии с имеющимися опубликованными данными при достигнутом существенном улучшении их точности (R(F > 2σ(F)) = 0.028). Несмотря на внесенные радиационные дефекты, монокристаллы Pb5Ge3O11 сохраняют кристаллическое строение и сегнетоэлектрические свойства. Показано, что проведенное облучение сохраняет полярную структуру при 295 K, но приводит к изменениям атомных смещений отдельных атомов. Сделано предположение, что радиационно-индуцированное изменение структуры Pb5Ge3O11 проходит по высокотемпературному типу, формируя новое структурное состояние, приближающееся к высокотемпературной модификации необлученного кристалла Pb5Ge3O11. Облучение приводит к постепенному уменьшению искажений и симметризации структуры. Существенно то обстоятельство, что кинетика и конечные продукты этих процессов значительно отличаются от таковых наблюдаемых только при термических воздействиях. Проведены расчеты величин полярных смещений, и их зависимость от дозы облучения указывает на тенденцию уменьшения полярных смещений в сегнетоэлектрике германате свинца под воздействием облучения.
Towards Understanding Information Systems Students’ Experience of Learning Introductory Programming: A Phenomenographic Approach
Authors: Govender Irene
Published: July 2021

Aim/Purpose: This study seeks to understand the various ways information systems (IS) students experience introductory programming to inform IS educators on effective pedagogical approaches to teaching programming.

Background: Many students who choose to major in information systems (IS), enter university with little or no experience of learning programming. Few studies have dealt with students’ learning to program in the business faculty, who do not necessarily have the computer science goal of programming. It has been shown that undergraduate IS students struggle with programming.

Methodology: The qualitative approach was used in this study to determine students’ notions of learning to program and to determine their cognitive processes while learning to program in higher education. A cohort of 47 students, who were majoring in Information Systems within the Bachelor of Commerce degree programme were part of the study. Reflective journals were used to allow students to record their experiences and to study in-depth their insights and experiences of learning to program during the course. Using phenomenographic methods, categories of description that uniquely characterises the various ways IS students experience learning to program were determined.

Contribution: This paper provides educators with empirical evidence on IS students’ experiences of learning to program, which play a crucial role in informing IS educators on how they can lend support and modify their pedagogical approach to teach programming to students who do not necessarily need to have the computer science goal of programming. This study contributes additional evidence that suggests more categories of description for IS students within a business degree. It provides valuable pedagogical insights for IS educators, thus contributing to the body of knowledge

Findings: The findings of this study reveal six ways in which IS students’ experience the phenomenon, learning to program. These ways, referred to categories of description, formed an outcome space.

Recommendations for Practitioners: Use the experiences of students identified in this study to determine approach to teaching and tasks or assessments assigned

Recommendation for Researchers: Using phenomenographic methods researchers in IS or IT may determine pedagogical content knowledge in teaching specific aspects of IT or IS.

Impact on Society: More business students would be able to program and improve their logical thinking and coding skills.

Future Research: Implement the recommendations for practice and evaluate the students’ performance.
FABRICATION OF 2-5 µM HYGROSCOPIC SEEDING MATERIAL FOR RAIN ENHANCEMENT PURPOSES

Published: July 2021

Abstract
Hygroscopic cloud seeding, which uses giant cloud condensation nuclei (GCCN) particles with diameters between 2-5 µm, has been known to be 100 times more effective compared to those that use hygroscopic flares. Micronisation through jet milling has been recognized as the most common and ubiquitous method used to obtain particles with such a narrow size (2-5 µm) distribution. This research has successfully developed and identified 2-5 µm NaCl powders mixed with 10% cab-o-sil anticaking agent and 2 (two) times jet milling frequency as a potential GCCN (hygroscopic) seeding material. We use a combination of jet mill micronisation, rough milling with a Cross-Beather Mill, and analytical sieving to produce powders with those mentioned above (2-5 µm) size distribution. We varied the anticaking agent percentage in the mixture and the jet milling process frequency to identify which parameters would result in the 2-5 µm size distribution. We then confirmed the micronisation results particle size distribution with a particle size analyzer (PSA) and its morphology with a scanning electron microscope (SEM) machine. The materials with the 10% cab-o-sil agent mixture were confirmed to have the aforementioned size distribution from the characterization results.

DID SOMETHING CHANGE IN CHAD AFTER THE OIL ERA? EVIDENCE FROM A ROLLING-WINDOWS ANALYSIS
Authors: KAYHAN Selim , MAHAMAT YACOUB Abdallatif
Published: July 2021

The volatility of oil prices has increased visibly in the last decade. Undoubtedly, the occurrence of volatility affects the economics of oil exporting and importing differently. Increases in oil prices positively affect economic indicators in oil exporting economies, while decreases have negative effects. In this regard, increases in volatility have attracted researchers’ attention, and a vast literature is found investigating both the economics of oil importing and exporting countries as well as advanced and emerging market economies.

The Republic of Chad’s economy differs from other economies because of its two different economic eras; the first was an oil import economy, which is energy dependent. The second is its oil era; this started in 2003 when oil reserves were discovered in the country. Due to Chad’s unique situation, we have examined the interactions between oil prices and Chad’s economic growth performance from 1963 to 2019 to see if its oil revenues have benefitted the economy or whether Chad’s situation falls under the “resource curse.” The results show that, while oil prices had been negative before the discovery of oil reserves, positive oil prices occurred after 2003. These prices did become negative again in 2018, which might be a sign of the resource curse.
