A Repartição de Operações do Estado-Maior do Corpo Expedicionário Português foi responsável pela coordenação das tropas portuguesas na frente ocidental e pela integração da força no dispositivo britânico. Elaborou o plano de defesa do setor atribuído e emitiu uma série de ordens para gerir as operações correntes. Com este trabalho pretendeu-se compreender a atividade desta repartição e o respetivo impacto no desempenho operacional do Corpo. Foram identificados os fatores que marcaram a beligerância portuguesa, que mais influência tiveram na repartição e no desempenho do Corpo, avaliado o impacto da estrutura da força e do seu Estado-Maior, identificados os fatores mais relevantes do setor atribuído e do seu dispositivo com impacto no desempenho e ainda determinado o papel da repartição durante a condução das operações. Com o intuito de atingir os objetivos propostos, foi analisado um conjunto de fontes, fundamentalmente do Arquivo Histórico Militar e da Biblioteca do Exército, para recolha de informação, e bibliografia nacional e estrangeira acerca do tema. Concluímos que a repartição contribuiu para o normal desempenho do CEP, não tendo sido identificados erros cometidos pela mesma com impacto negativo na prestação da força. Abstract: The Operations Division of the General Staff of the Portuguese Expeditionary Corps was responsible for coordinating the Portuguese troops on the western front and for the integration of the force in British defense system. It prepared the defense plan for the assigned sector, and issued several orders to manage current operations. This work was intended to understand the activity of this division and its impact on the operational performance of CEP. Were identified the factors that marked the Portuguese belligerence which more influence had in the Operations Division and CEP's performance, assessed the impact of the force structure and its staff, identified the most important factors of the assigned sector and its force structure with impact on performance and also determined the role of the operations division during the operations. In order to achieve the proposed goals, we studied a number of sources, mainly from the Military Historical Archives and the Library of the Army for information collection, and also from national and foreign literature on the subject. We conclude that the operations division contributed to the normal performance of the CEP, and didn’t identify errors committed by it with negative impact on the force performance.

A ferrugem asiática é uma importante doença na cultura da soja. Os padrões espaciais e temporais de ocorrência e de severidade das epidemias nas diferentes safras são variáveis em função das condições climáticas prevalentes, principalmente da precipitação. As variabilidades interanual e espacial do risco climático de epidemias de ferrugem asiática no Estado do Rio Grande do Sul foram avaliadas com um modelo de predição da severidade máxima da doença com base na precipitação. Foram utilizadas séries históricas de 25 anos de precipitação diária no período crítico para o desenvolvimento da doença (janeiro a março) em 24 localidades na região produtora do Estado. Estatística descritiva e funções probabilidade de excedência (FPE) foram usadas para avaliar a variação temporal e espacial do risco nessas localidades. O impacto das fases quente e fria do fenômeno climático El Niño - Oscilação Sul (ENOS) no período de outubro a dezembro (OND) foi avaliado em quatro localidades com séries de dados de 50 anos, também usando FPE. Os resultados mostraram um risco de 50% para epidemias de até 37% de severidade máxima na média das localidades, enquanto que o risco de epidemias com severidade acima de 60% variou de 0 a 20% nas localidades, sendo mais alto na região Norte do Estado. Na ocorrência de uma fase quente do ENOS no período OND o risco de exceder a mediana aumenta em torno de 20% nas quatro localidades avaliadas, sendo mais pronunciado em algumas localidades.

This study evaluates the influence of depth and environmental parameters on the development of Gracilaria birdiae Plastino & Oliveira (Gracilariaceae Rhodophyta) in an organic shrimp pound (Litopenaeus vannamei) under euthrophical conditions. PVC structures (module) witch four ropes laden with 150 g of macroalgae each, were kept during 35 days at three different depths (surface, 10 and 20 cm depth). Wet biomass weighing and environmental parameters (temperature, salinity, turbidity, pH, transparence, precipitation, evaporation, insolation, accumulated solar radiation, nitrite, nitrate, ammonium and orthophosphate) were measured weekly. At all three proposed depths, the macroalgae displayed a higher biomass at the end of experiment than at the initial inoculations. The module kept at a 10 cm depth presented the greatest average biomass (186,3), followed by that kept at 20 cm (180,4 g) and the surface module (169,9 g). Biomass variations showed algae to suffer the direct effects of depths. Biomass loss was associated with the factors that influence light penetration, such as sediment deposits above the thallus, rate of evaporation and precipitation. The smallest loses occurred in the algae kept on surface (0,16%), followed by the algae kept at 20 cm (0,20%) and 10 cm (0,22%). The specific growth rate (SGR) of G. birdiae showed no significant difference between the three depths nor the sample periods. Nevertheless, the modules kept at 10 and 20 cm depths presented similar growth evolution, both growing 0,38%·per day-1, while the module kept on surface had an average SGR of 0,36%·day-1. The models related to growth rate demonstrated temperature, salinity, pH, orthophosphate, ammonium, precipitation and turbidity as the principal environmental parameters influencing the development of G. birdiae

Trata-se de um estudo de revisão com o objetivo de investigar os fatores determinantes do desmame precoce, no intuito de se compreender os danos causados à saúde das crianças com essa prática, bem como a importância do aleitamento materno exclusivo. Por meio de uma pesquisa de revisão bibliográfica em artigos, livros e manuais do Ministério da Saúde, verificou-se que muitas são as causas que conduzem ao abandono do aleitamento materno, dentre elas a ausência de informações das mães sobre a importância da amamentação, influência negativa da mídia que estimula o uso de alimentos em substituição ao leite materno, o retorno da mulher ao trabalho, usos e costumes relacionados à cultura popular, o relacionamento da mãe com o bebê após o parto, além de preocupações estéticas da mãe em relação ao seu corpo após a gravidez e a amamentação. Sendo assim, o estudo mostrou que o desmame ainda é uma realidade negativa ressaltada pela literatura e, por isso, leva à necessidade de se intensificar ações de promoção ao aleitamento materno no sentido de esclarecer melhor sobre a importância do aleitamento e sobre os aspectos negativos do desmame precoce.

Este trabalho, fundamentado na pesquisa bibliográfica narrativa, propôs avaliar se a permanência das crianças na creche reduz a incidência de cáries quando comparadas com crianças da mesma faixa etária que não a frequentam e eram desassistidas de água tratada (fluoretada). O cenário escolhido foi a área adscrita da Estratégia Saúde da Família Pedreira do Instituto, situado em Itabira Minas Gerais. Foi realizado um estudo observacional transversal (piloto) com uma amostra composta por 54 crianças de ambos os sexos. A coleta de dados foi realizada através de consulta da Ficha A e das Fichas Odontológicas dessas crianças (dados secundários) separadas aleatoriamente em dois grupos - um grupo de 27 crianças residentes na zona urbana e que frequentam a Creche Irmã Maria Clara, que consumiam água fluoretada e estavam vinculadas a políticas públicas de prevenção como escovação supervisionada, aplicação tópica de flúor, dieta balanceada e orientações de promoção de saúde e prevenção da patologia cárie. O outro grupo também de 27 crianças que não estavam na Creche e eram desprovidas de água tratada (fluoretada), por residirem em zona rural, além de não estarem inseridas em programas de políticas públicas preventivas para a patologia cárie. Foi encontrada uma média de 0,59 dentes cariados no grupo das crianças que frequentavam a creche contra uma média de 0,48 no grupo das que não frequentavam a instituição. Uma análise apontada pelos gráficos mostrou que a prevalência da patologia cárie nas crianças da Creche, apesar de maior, manifestou-se de forma mais controlada, uma vez que o número de dentes cariados por criança é maior no grupo que não a frequentavam. Com este estudo percebeu-se que apesar do número absoluto de dentes cariados ser maior nas crianças que frequentavam a Creche, a quantidade de dentes acometidos pela doença por indivíduo é maior nas crianças que não estavam nela inseridas, sugerindo que à medida que o tempo passa o fator proteção creche com suas políticas públicas preventivas aumenta.

The composition and biological activities of propolis, a resinous hive product collected by honeybees from various plant sources, depends on various factors such as season and vegetation of the area. The aim of this study was to evaluate the influence of the seasonal effect on the ethanolic extracts of Brazilian propolis (EEP) type 6 and type 12, collected during 6 months in terms of antibacterial activity and phenolic composition. The antimicrobial properties were evaluated by MIC and MBC on S. mutans Ingbritt 1600 and the profile of chemical composition by UV-visible spectrophotometry, HPLC-RF and GC-MS. The results demonstrated that the season in which propolis is collected influences its chemical composition, resulting in modifications in its antibacterial activity.

This research studied the effect of low density polyethylene packaging and storage temperature on the preservation of fresh-cut (minimally processed) cabbage. The cabbages, previously cooled to a temperature of 10 ºC, were selected, washed, cut in four parts (with the central stalk removed), sanitized, cut in strips, rinsed, put in the centrifuge, weighed and stored in plastic packaging of low density polyethylene (70 µm), and then stored in cold chambers at temperatures of 1 and 10 ºC for 20 days. The following aspects were evaluated: carbon dioxide, oxygen and ethylene in the internal atmosphere of the package as well as, pH, titratable acidity, total soluble solids, vitamin C, loss of fresh mass and the total soluble solids/acidity in the fresh-cut cabbage ratio. The experimental design was entirely casual, with three repetitions. The analysis parameters, except for the vitamin C, loss of fresh mass and ethylene, presented significant variation between the temperatures and days of storage. The cabbage stored at a temperature of 1 ºC presented a shelf life of around 15 days, significantly higher than that stored at 10 ºC. At this temperature, on the 8th day of storage, the product was completely decayed, unfit for commercialization or consumption.

Edible mushroom are highly perishable foods. Drying is an alternative to provide safe storage. In this work, the effects of some drying parameters on the quality of Shiitake mushroom were investigated: geometry of the raw material (whole and sliced), drying temperature (50 °C and 70 ºC) and final moisture content (5% and 15% wb). Experimental kinetics of drying was built and color and texture analyses were done in fresh and in rehydrated dried product. The effect of parameters was evaluated by analysis of variance and test of multiple comparisons. Drying kinetics showed that drying happened in falling-rate period and sliced mushroom dried at 70 ºC required lesser drying time than other treatments. Mushroom dried at 70 ºC showed less darkening. Drying time affected mushroom quality, evaluated by great hardness, gummosis and darkening.

In this work the performance of a sugar cane chopped harvester was analysed when fed with two sugar cane mass flows, measuring the invisible losses, which are impossible to measure in the field, harvester sugar cane cleaning efficiency and air velocity on extractors exit. The trial was done under controlled conditions at Copersucar Technology Center in January 2000. The results showed that the flow of sugar cane through the harvester doesn't influence the magnitudes of total invisible losses and raw material cleaning efficiency. The mean air velocity on the primary extractors exit was 12.0 m s-1, and 9.2 m s-1 on the secondary extractor, with a coefficient of variation of 21%, indicating that the poor cleaning performance of the harvester could be related to air velocity difference inside the extractor. Analyzing the data collected in the trials, it was possible to conclude that invisible losses in sugar cane harvester were 10% and the cleaning efficiency was 87%.

In order to determine the energy needed to artificially dry an agricultural product the latent heat of vaporization of moisture in the product, H, must be known. Generally, the expressions for H reported in the literature are of the form H = h(T)f(M), where h(T) is the latent heat of vaporization of free water, and f(M) is a function of the equilibrium moisture content, M, which is a simplification. In this article, a more general expression for the latent heat of vaporization, namely H = g(M,T), is used to determine H for cowpea, always-green variety. For this purpose, a computer program was developed which automatically fits about 500 functions, with one or two independent variables, imbedded in its library to experimental data. The program uses nonlinear regression, and classifies the best functions according to the least reduced chi-squared. A set of executed statistical tests shows that the generalized expression for H used in this work produces better results of H for cowpea than other equations found in literature.

The present paper brings about a possible articulation between translation and body from a non-sublimated, pragmatic perspective on meaning, as suggested by Wittgenstein in his Philosophical Investigations. By considering theoretical elaborations within embodied realism and elsewhere on the role of the body in cognitive processes, together with a critique of the concept of translation somatics, as proposed by Douglas Robinson (1991), the paper highlights the situated and social character of the translator's body.

The aim of this study was to investigate the influence of different assessment time periods of submaximal tests on the determination of the maximal accumulated oxygen deficit (MAOD), through the adoption of different time slots of 4 to 6, 6 to 8 and 8 to 10 min. Ten cyclists with mean age of 27.5 ± 4.1 years, body mass 74.4 ± 12.7 kg and time experience of 9.8 ± 4.7 years participated in this study. The athletes underwent an incremental exercise test to determine the peak oxygen consumption (VO2peak), and four submaximal constant work-load test sessions (60, 70, 80 and 90% VO2peak) of 10 min in order to estimate the O2 demand (DEO2). The mean VO2 values obtained on each constant work-load for the 4 to 6, 6 to 8 and 8 to 10 min time-periods intervals were used to perform a linear regression between the intensity and O2 consumption for each time-period. In addition, the subjects performed one supramaximal rectangular test (110% VO2peak) for the quantification of MAOD. There was no significant difference in VO2 between the different time-periods for all submaximal tests (P> 0.05). Similarly, no significant difference was found in DEAO2 and MAOD (P> 0.05). Furthermore, the values of MAOD for the three time-periods intervals showed good agreement and strong correlation. Thus, the data suggest that the submaximal tests used to estimate the values of MAOD can be reduced, at least in this type of sample, and with the use of a cycle simulator.

BACKGROUND: Changes in heart rate during rest-exercise transition can be characterized by the application of mathematical calculations, such as deltas 0-10 and 0-30 seconds to infer on the parasympathetic nervous system and linear regression and delta applied to data range from 60 to 240 seconds to infer on the sympathetic nervous system. The objective of this study was to test the hypothesis that young and middle-aged subjects have different heart rate responses in exercise of moderate and intense intensity, with different mathematical calculations. METHODS: Seven middle-aged men and ten young men apparently healthy were subject to constant load tests (intense and moderate) in cycle ergometer. The heart rate data were submitted to analysis of deltas (0-10, 0-30 and 60-240 seconds) and simple linear regression (60-240 seconds). The parameters obtained from simple linear regression analysis were: intercept and slope angle. We used the Shapiro-Wilk test to check the distribution of data and the t test for unpaired comparisons between groups. The level of statistical significance was 5%. RESULTS: The value of the intercept and delta 0-10 seconds was lower in middle age in two loads tested and the inclination angle was lower in moderate exercise in middle age. CONCLUSION: The young subjects present greater magnitude of vagal withdrawal in the initial stage of the HR response during constant load exercise and higher speed of adjustment of sympathetic response in moderate exercise.
