Association between functional fitness and overweight in elderly women

The purpose of this study was to verify the association between functional fitness (FF) and excessive fatness (EF) in aged women. Three hundred ninety four women, averaged 69.4 years of age (DP = 3.4 years), participated in the study. FF was measured by means of a battery of motor tests. EF was determined by corporal mass and height measurements. FF was compared with AAHPERD normative values. Chi-square test (p < .05) was applied in order to verify an association between FF and EF. EF prevalence was 46.5% and there was an association (p < .05) between the index of functional aptitude (IAFG) and EF. Among those with EF, 87.8% presented a weak IAFG. EF was associated with a 5.07 (IC 95% = 3.12 – 7.14) times greater chance of lower FF. Results point to the conclusion that morphologic condition (EF) needs to be considered in evaluating FF in aged women

O Currículo Da Educação Física Na Rede Municipal De Barueri: As Percepções Dos Professores

This study aimed to know physical education teachers’ perceptions in the city of Barueri, São Paulo, about the reference plan for the PE curricular component and on its implementation process. Qualitative research was conducted including interviews with fourteen teachers, which were the focus of content analysis. It found that teachers favor a common curriculum that standardizes pedagogical practice, but they want some flexibility to adapt it to their views and to students’ characteristics. Teachers criticize the curriculum’s design, content organization and especially implementation. Tensions and conflicts were found in curriculum development as well as interdependence between curriculum dimensions. Thus, teachers are changed by interference of the official curriculum and the curriculum is changed by teachers’ action. © 2017, Universidade Federal do Rio Grande do Sul.

Assessment of the stability of LTA zeolites under natural gas drying TSA conditions

[EN] The main features in cationic LTA zeolites that are likely to impact its potential hydrothermal stability are interconnected. The Al content and the compensating cation play an important role in the water adsorption but their influence on the zeolite performance in thermal cycles is yet to be understood. In this study, four LTA zeolite samples were synthetized with distinct Si/Al ratios in sodium and potassium forms. They underwent a Premature Aging Protocol (PAP) that took into account the operating conditions typically found in temperature swing adsorption processes. The Si/Al ratio per se did not impact in the crystallinity upon aging, but the presence of a high amount of potassium cations (Si/Al = 1) led to the amorphization of the zeolite structure. The results from XPS and NMR techniques indicate the Al migration from the outer surface to the inner cages occurs upon aging. Chemical analysis by XRF and ICP-OES associated with 27Al NMR analysis reveal that the presence of EFAl is particularly significant in the sample with the largest Si/Al ratio (5) and is correlated to a much larger C deposition upon aging. TG/DTG and TPD-NH3 experiments suggest that acid sites in the zeolite structures act as a double-edged sword, by enhancing water adsorption while also leading to carbon accumulation. CO2 isotherms at 0 oC reveal the reduction of the microporosity after aging, whereas the Al content is proportional to the water adsorption uptake, particularly at low pressures (below 10 mbar). The material with an intermediate Si/Al ratio and in Na-form (LTAc-SiAl2-Na) combines excellent hydrothermal stability with a high-water affinity and uptake.The authors acknowledge financial support from Petrobras (Brazil) project 2018/00130-5, CAPES (Brazil), particularly in the frame of project CAPES/Print 88887.311867/2018-00 and Servicios Centrales de Apoyo a la Investigacion - SCAI.

Marine diatoms grown in chemostats under silicate or ammonium limitation. III. Cellular chemical composition and morphology of Chaetoceros debilis, Skeletonema costatum , and Thalassiosira gravida

Three marine diatoms, Skeletonema costatum, Chaetoceros debilis , and Thalassiosira gravida were grown under no limitation and ammonium or silicate limitation or starvation. Changes in cell morphology were documented with photomicrographs of ammonium and silicate-limited and non-limited cells, and correlated with observed changes in chemical composition. Cultures grown under silicate starvation or limitation showed an increase in particulate carbon, nitrogen and phosporus and chlorophyll a per unit cell volume compared to non-limited cells; particulate silica per cell volume decreased. Si-starved cells were different from Si-limited cells in that the former contained more particulate carbon and silica per cell volume. The most sensitive indicator of silicate limitation or starvation was the ratio C:Si, being 3 to 5 times higher than the values for non-limited cells. The ratios Si:chlorophyll a and S:P were lower and N:Si was higher than non-limited cells by a factor of 2 to 3. The other ratios, C:N, C:P, C:chlorophyll a , N:chlorophyll a , P:chlorophyll a and N:P were considered not to be sensitive indicators of silicate limitation or starvation. Chlorophyll a , and particulate nitrogen per unit cell volume decreased under ammonium limitation and starvation. NH 4 -starved cells contained more chlorophyll a , carbon, nitrogen, silica, and phosphorus per cell volume than NH 4 -limited cells. N:Si was the most sensitive ratio to ammonium limitation or starvation, being 2 to 3 times lower than non-limited cells. Si:chlorophyll a , P:chlorophyll a and N:P were less sensitive, while the ratios C:N, C:chlorophyll a , N:chlorophyll a , C:Si, C:P and Si:P were the least sensitive. Limited cells had less of the limiting nutrient per unit cell volume than starved cells and more of the non-limiting nutrients (i.e., silica and phosphorus for NH 4 -limited cells). This suggests that nutrient-limited cells rather than nutrient-starved cells should be used along with non-limited cells to measure the full range of potential change in cellular chemical composition for one species under nutrient limitation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46631/1/227_2004_Article_BF00392568.pd
