O objetivo deste foi avaliar o perfil nutricional de idosas frequentadoras da Faculdade da Terceira Idade, de São José dos Campos, Estado de São Paulo. A pesquisa foi transversal e controlada, constituída por 40 idosas, com média de idade de 68,22 anos. Foi realizada a avaliação antropométrica (índice de massa corporal, circunferência da cintura, razão cintura-quadril, prega cutânea triciptal e circunferência muscular braquial) e aplicação do inquérito alimentar. Os resultados mostraram inadequação do estado nutricional da maioria (52,5%) das idosas pelo índice de massa corporal, circunferência da cintura (75%) e razão cintura-quadril (90%). A maioria das idosas apresentou adequação em relação à reserva de tecido adiposo e muscular braquial. Verificou-se neste grupo uma baixa ingestão de fibra alimentar, com média de 10,76 g. Pode-se concluir que prevaleceu a inadequação do estado nutricional, indicativa de sua maior susceptibilidade à morbidade e à mortalidade e inadequação pela maioria idosas em relação ao consumo alimentar de fibra.

Authors: Souza Rozana Aparecida de 
Published: March 2021

Este artigo é uma revisão da literatura sobre o debate contemporâneo travado acerca da anticoncepção de emergência (AE), método contraceptivo comumente conhecido como pílula do dia seguinte.. A AE é um método normatizado pelo Ministério da Saúde desde 1996 para se evitar uma gravidez indesejada, tem seu uso recomendado em situações de emergência, como em casos de violência sexual, relação sexual desprotegida e nos casos de possível falha de outro método (ex: ruptura de camisinha). Foram levantadas pesquisas e estudos nacionais e internacionais sobre os mitos e barreiras que envolvem o acessso e o uso deste contraceptivo. O artigo apresenta um resgate sobre a história da contracepção no Brasil e sobre a constituição das políticas públicas de atenção integral a saúde da mulher, localizando a AE nestes contextos, bem como dados relevantes das pesquisas levantadas.

Authors: Almeida Nívea Veiga , Neves Alden Santos 
Published: March 2021

A Doença de Crohn (DC) é uma doença inflamatória intestinal de causa desconhecida que acomete pessoas de 20 á 50 anos de idade de ambos os sexos e está associada á manifestações extraintestinais secundárias ao processo inflamatório de base, sendo a nefrolitíase a manifestação urogenital mais comum acometendo de 12 a 28% dos pacientes, devido a alterações na mucosa intestinal e, consequentemente, má absorção, esses cálculos estão associados à hiperoxalúria, além de outras alterações metabólicas associadas. Por esse motivo torna-se importante o conhecimento das alterações metabólicas existentes, para que se possa oferecer o acompanhamento nutricional adequado, e, em específico, no presente estudo, o tratamento nutricional oral que objetiva o controle da ingestão de glutamina, ácidos graxos ômega 3, proteínas, citrato, fibras, magnésio, líquidos, probióticos, fibras solúveis, oxalato e citrato, aumentando assim uma melhor qualidade de vida para estes pacientes. Objetivo:descrever a relação existente entre a DC e Nefrolitíase, e analisar o tratamento nutricional mais adequado.Metodologia: revisão bibliográfica de artigos científicos e sites oficiais. Conclusão: apesar de existir relação entre as doenças citadas, há necessidade de maiores estudos, pois não existem ainda diretrizes nutricionais para nefrolitíase em pacientes DC.

O objetivo deste artigo é apresentar o Zoneamento Territorial para a Cana-de-açúcar no Estado de São Paulo (ZTC), que é uma contraproposta ao Zoneamento Agroambiental para o setor sucroalcooleiro (ZAA). Partiu-se da hipótese de que o ZAA serve apenas como instrumento para legitimar a expansão territorial do cultivo de cana-de-açúcar e do agronegócio canavieiro em detrimento da agricultura familiar, pois em sua elaboração não foi considerado a existência dos assentamentos rurais e da agricultura familiar. Para a elaboração do ZTC, além dos dados referentes às características edafoclimáticas e de restrições ambientais, também utilizados pelo ZAA, inserimos dados referentes aos territórios dos assentamentos rurais e da agricultura familiar, ou seja, para a elaboração do ZTC consideramos a existência dos múltiplos territórios e a existência da Questão Agrária. Por fim, a partir do ZAA e do ZTC, analisamos a expansão da área plantada com cana-de-açúcar no Estado de São Paulo nos anos que compreende o período de 2003 a 2013.

A “febre pela terra”, disputa territorial global que surge partir da convergência de crises de 2008, apresentou consequências diversas. Uma delas é o controle de terras pelo capital transnacional, direcionado à reprodução, valorização e proteção de capitais, produção de commodities, produção de agrocombustíveis ou tão somente a especulação. Esta “corrida pela terra” culminou no surgimento e crescimento do fenômeno de Acaparamiento de Tierras ou apropriações capitalistas transnacionais de terras, também conhecido como Estrangeirização. Neste cenário, a América Latina tem sido um dos principais destinos da busca por terras pelo capital transnacional. Brasil e Argentina são avaliados neste artigo como os países latino-americanos com maior índice de Acaparamiento e Estrangeirização de Terras até 2019. Funcionando como países-chave para o acesso à América Latina, estes países também são avaliados enquanto principais exportadores latino-americanos de commodities como soja e milho. Por fim, toma-se como relevante o papel da China enquanto apropriador capitalista e que busca o controle de terras agricultáveis no Brasil e na Argentina. Para tal, são avaliadas as relações sino-brasileiras e sino-argentinas, os contratos que revelam o controle de terras pela China no Brasil e na Argentina e qual seu grau de sua atuação nestes países enquanto acaparador e estrangeirizador de terras latinas.

Estudio sobre desempeño competitivo de PyMEs industriales. El caso del Sector Industrial Planificado de Almirante Brown
Authors: Bazque Héctor Gabriel 
Published: March 2021

El concepto de desarrollo económico ha evolucionado notablemente hacia la segunda mitad del siglo XX. Con la caída del Estado de bienestar, y el surgimiento de exitosas experiencias de crecimiento europeo (como el caso de los distritos industriales de España, y del Centro y Nordeste de Italia, entre otros), el escenario local pasó a convertirse en el potencial “espacio de desarrollo”. La reconceptualización económica de “lo local”, bajo el nombre de “territorio”, otorgó renovada importancia a las pequeñas y medianas empresas.
Entendiendo al Sector Industrial Planificado de Almirante Brown (SIPAB) como un territorio industrial de importancia del conurbano sur de la Provincia de Buenos Aires, el presente trabajo busca responder ¿qué tipo de competitividad se logra en el SIPAB? Y ¿cuál fue el desempeño reciente de las firmas pertenecientes a este distrito industrial?
Atmospheric boundary layer height estimation from aerosol lidar: a new approach based on morphological image processing techniques

Published: March 2021

Abstract. The atmospheric boundary layer (ABL) represents the lowermost part of the atmosphere directly in contact with the Earth's surface. The estimation of its depth is of crucial importance in meteorology and for anthropogenic pollution studies. ABL height (ABLH) measurements are usually far from being adequate, both spatially and temporally. Thus, different remote sensing sources can be of great help in growing both the spatial and temporal ABLH measurement capabilities. To this aim, aerosol backscatter profiles are widely used as a proxy to retrieve the ABLH. Hence, the scientific community is making remarkable efforts in developing automatic ABLH retrieval algorithms applied to lidar observations. In this paper, we propose a ABLH estimation algorithm based on image processing techniques applied to the composite image of the total attenuated backscatter coefficient. A pre-processing step is applied to the composite total backscatter image based on morphological filters to properly set-up and adjust the image to detect edges. As final step, the detected edges are post-processed through both mathematical morphology and an object-based analysis. The performance of the proposed approach is assessed on real data acquired by two different lidar systems, deployed in Potenza (Italy) and Évora (Portugal), belonging to the European Aerosol Research Lidar Network (EARLINET). The proposed approach has shown higher performance than the benchmark consisting of some state-of-the-art ABLH estimation methods.
Inferring thermospheric composition from ionogram profiles: a calibration with the TIMED spacecraft
Authors: Scott Christopher J. , Jones Shannon , Barnard Luke A. 
Published: March 2021

Abstract. We present a method for augmenting spacecraft measurements of thermospheric composition with quantitative estimates of daytime thermospheric composition below 200 km, inferred from ionospheric data, for which there is a global network of ground-based stations. Measurements of thermospheric composition via ground-based instrumentation are challenging to make, and so details about this important region of the upper atmosphere are currently sparse. The visibility of the F1 peak in ionospheric soundings from ground-based instrumentation is a sensitive function of thermospheric composition. The ionospheric profile in the transition region between F1 and F2 peaks can be expressed by the “G” factor, a function of ion production rate and loss rates via ion–atom interchange reactions and dissociative recombination of molecular ions. This in turn can be expressed as the square of the ratio of ions lost via these processes. We compare estimates of the G factor obtained from ionograms recorded at Kwajalein (9∘ N, 167.2∘ E) for 25 times during which the Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics (TIMED) spacecraft recorded approximately co-located measurements of the neutral thermosphere. We find a linear relationship between G and the molecular-to-atomic composition ratio, with a gradient of 2.55±0.40. Alternatively, using hmF1 values obtained by ionogram inversion, this gradient was found to be 4.75±0.4. Further, accounting for equal ionisation in molecular and atomic species yielded a gradient of 4.20±0.8. This relationship has potential for using ground-based ionospheric measurements to infer quantitative variations in the composition of the neutral thermosphere via a relatively simple model. This has applications in understanding long-term change and the efficacy of the upper atmosphere on satellite drag.
Evaluating optically stimulated luminescence rock surface exposure dating as a novel approach for reconstructing coastal boulder movement on decadal to centennial timescales

Published: March 2021

Abstract. Wave-transported boulders represent important records of
storm and tsunami impact over geological timescales. Their use for hazard
assessment requires chronological information on their displacement that in
many cases cannot be achieved by established dating approaches. To fill this
gap, this study investigated, for the first time, the potential of optically
stimulated luminescence rock surface exposure dating (OSL-RSED) for
estimating cliff-detachment ages of wave-transported coastal boulders. The
approach was tested on calcarenite clasts at the Rabat coast, Morocco.
Calibration of the OSL-RSED model was based on samples with rock surfaces
exposed to sunlight for ∼ 2 years, and OSL exposure ages were
evaluated against age control deduced from satellite images. Our results
show that the dating precision is limited for all targeted boulders due to
the local source rock lithology which has low amounts of quartz and
feldspar. The dating accuracy may be affected by erosion rates on boulder
surfaces of 0.02–0.18 mm yr−1. Nevertheless, we propose a robust relative
chronology for boulders that are not affected by significant
post-depositional erosion and that share surface angles of inclination with
the calibration samples. The relative chronology indicates that (i) most
boulders were detached from the cliff by storm waves; (ii) these storms
lifted boulders with masses of up to ∼ 24 t; and (iii) the
role of storms in the formation of boulder deposits along the Rabat coast
is more significant than previously assumed. Although OSL-RSED cannot
provide reliable absolute exposure ages for the coastal boulders in this
study, the approach has large potential for boulder deposits composed of
rocks with larger amounts of quartz or feldspar and less susceptibility to
erosion.

Published: March 2021

Abstract. Effective numerical weather forecasting is vital in arid regions like the
United Arab Emirates (UAE) where extreme events like heat waves, flash
floods, and dust storms are severe. Hence, accurate forecasting of
quantities like surface temperatures and humidity is very important. To
date, there have been few seasonal-to-annual scale verification studies with
WRF at high spatial and temporal resolution. This study employs a convection-permitting scale (2.7 km grid scale)
simulation with WRF with Noah-MP, in daily forecast mode, from 1 January to
30 November 2015. WRF was verified using measurements of 2 m air temperature
(T2 m), 2 m dew point (TD2 m), and 10 m wind speed (UV10 m) from 48 UAE
WMO-compliant surface weather stations. Analysis was made of seasonal and
diurnal performance within the desert, marine, and mountain regions of the
UAE. Results show that WRF represents temperature (T2 m) quite adequately during
the daytime with biases ≤+1 ∘C. There is, however, a
nocturnal cold bias (−1 to −4 ∘C), which increases during hotter
months in the desert and mountain regions. The marine region has the
smallest T2 m biases (≤-0.75 ∘C). WRF performs well regarding
TD2 m, with mean biases mostly ≤ 1 ∘C. TD2 m over the marine
region is overestimated, though (0.75–1 ∘C), and nocturnal
mountain TD2 m is underestimated (∼-2 ∘C). UV10 m
performance on land still needs improvement, and biases can occasionally be
large (1–2 m s−1). This performance tends to worsen during the hot
months, particularly inland with peak biases reaching ∼ 3 m s−1. UV10 m is better simulated in the marine region (bias ≤ 1 m s−1). There is an apparent relationship between T2 m bias and UV10 m
bias, which may indicate issues in simulation of the daytime sea breeze.
TD2 m biases tend to be more independent. Studies such as these are vital for accurate assessment of WRF nowcasting
performance and to identify model deficiencies. By combining sensitivity
tests, process, and observational studies with seasonal verification, we can
further improve forecasting systems for the UAE.

Abstract. Long-term (10 years) application of conservation tillage following conversion from conventional tillage (CT) can achieve a new equilibrium in the soil environment, which is vital to reverse soil biodiversity declines and fulfil the goal of maintaining agroecosystem sustainability. However, in such a situation, how the soil community regulates nutrient cycling impacting crop yield is not well documented. Therefore, the relations between mineralized nitrogen (N) delivered by soil food web and soybean (Glycine max Merr.) yield were investigated after 14 years application of CT, reduced tillage (RT) and no tillage (NT) in a black soil (Typic Hapludoll) of Northeast China. We hypothesized that soil mineralizable N would increase with the complexity of the soil food web, and that the trophic groups involved in associating N mineralization with crop yield will vary with soil depth in the conservation tillage practice. During the soybean growing season, soil organisms, including bacteria, fungi, nematodes, mites and collembolans, were extracted and identified monthly from 0–5 and 5–15 cm soil depths to estimate the complexity of the food web indicated by the species richness and connectance indices, and to simulate the mineralized N using energetic food web modelling. The species richness and connectance of
the food web at both soil depths were significantly affected by tillage
practices, and their values decreased of the order of NT > RT > CT. A similar trend was also revealed for the simulated N mineralization, that is, the mineralized N released either from the functional feeding guilds or from the energy pathways of the food web were greater in RT and NT than in CT at both soil depths. Multiple linear regression analysis showed that soil organisms involved in coupling the mineralized N with soybean yield were different at different soil depths, in which fungal and root pathways at 0–5 cm and bacterial pathway at 5–15 cm were the driving factors for the supply of mineralized N to soybean in NT and RT soils. These results support our hypothesis and highlight the essential role of soil food web complexity in coupling N mineralization and crop yield after long-term application of conservation tillage. Additionally, the current modelling work provides basic hypotheses for future studies to test the impact of soil biodiversity or specific functional guilds on the fate of N in agro-ecosystems.
