title: Assembly and Testing of a Thermal Control Component Developed in Brazil

description: ABSTRACT: The optical solar reflector is basically a mirror of second surface with low absorptivity/emissivity ratio and negligible degradation in the space environment, which makes it an excellent coating for thermal control of satellites. It works as a radiator and is used in particular parts of the external surfaces of the satellites in order to reject the undesirable heat to the deep space. In the Brazilian Space Programs, the radiators of the satellites are generally painted with special white paints in order to reject heat instead of the use of optical solar reflector. The problem of white-ink radiators is the high degradation of the thermo-optical properties that happen over the useful lives. Thus, a process of manufacturing and assembly of optical solar reflector was developed in Brazil. To validate this process in terms of mechanical and thermal properties, 3 types of optical solar reflector radiators were manufactured, and their absorptivity and emissivity properties at the temperature of 23 ºC were measured. Optical solar reflector coupons were mounted on aluminum plates to perform vibration, thermal vacuum and thermal-shock tests. A study was also done to optimize the thickness of the glue to fix the structure of the satellite on the optical solar reflector. It showed an excellent environmental stability and maintained its thermo-optical characteristics after the tests.

title: HUMAN FOLLICLE STIMULATING HORMONE (hFSH) AND THYROXINE (T4) IN SURVIVAL MAINTENANCE AND IN VITRO GROWTH PROMOTION OF CAPRINE PREANTRAL FOLLICLES

description: The aim of this study was to investigate the interaction of human FSH (10ng/ml) with T4 (20ng/mL) on survival, activation and growth of preantral follicles cultured in vitro for 28 days. Fragments of non-cultured and cultured ovarian tissue were processed for classic histology and transmission electron microscopy. The results showed a reduction in the survival rate in all the media tested (one to 28 days) when compared to the fresh control. However the treatment with T4/hFSH for seven days of culture maintained the rate similar to the control. The media tested by one and 28 days reduced the percentage of primordial follicles in all periods of culture. However, T4/hFSH on day one of culture remained similar to the fresh control. None of the media were able to keep the percentage of the developing follicles. It was observed that the follicular diameter in the medium with T4/hFSH remained similar to the fresh control. The ultrastructural analysis confirmed the integrity of follicles cultured for seven days in a medium supplemented with T4/hFSH. In conclusion, the medium with T4/hFSH is able to maintain the survival, promote the activation, and the ultrastructural integrity of caprine preantral follicles for until seven days.

title: PHYSICAL ATTRIBUTES OF SOIL AFTER SWINE WASTEWATER APPLICATION AS COVER FERTILIZER ON MAIZE CROP AND BLACK OATS SEQUENCE

description: ABSTRACT The rate of swine wastewater application (SW) in agricultural production could result in the replacement of chemical fertilizers. However, SW destroys soil physical properties by decreasing pore bulk, which negatively affects both crop yield and development. In this context, this study aimed at monitoring the influence of swine wastewater as a cover fertilizer in maize and black oats in sequence on soil physical properties. Five application rates (0, 100, 200, 300 and 537 m3ha - 1 equivalent to 0, 11.2, 22.3, 33.5 and 60 kg ha-1 N, respectively, based on the average nitrogen concentration in SW) were tested with four replications each. In the studied area, soil porosity, density, and water content, before maize sowing and at the end of the cycles of maize and black oats, were determined by the volumetric ring method. Data were submitted for regression analyses. There was a reduction in the macroporosity and total porosity of the soil when the SW application rate, before maize cultivation, was higher. The introduction of black oats helped to improve the physical quality of the soil and reduced the compaction of the surface layer from 0 to 15 cm and 100 to 300 m3 ha-1 SW rates.

title: Spatial variability of physical attributes and soil aggregates in archaeological dark dirt under pasture

description: Abstract Some areas of archaeological dark dirt in the Amazon have been used with pasture that has generated great concern regarding changes in soil physical attributes and its aggregation state. The objective of this study was to evaluate the spatial variability and possible modifications of soil physical and aggregate attributes in archaeological black dirt under pasture. A grid of 80 x 56m with 88 sampling points distributed in 8 x 8m were marked. Soil layers at 0-0.05, 0.05-0.10, and 0.10-0.20m were analyzed for: soil density (SD), total organic carbon (TOC), carbon stock (C stock), meanweight diameter (MWD), macroporosity (Macro), microporosity (Micro), and total porosity (TP). From semivariograms tests it was verified the occurrence of spatial dependence. Even with major pasture cover in the study area it was observed that the values of Ds, Macro, and VTP were above or below the reference values, which may cause restriction for root growth of plants and water infiltration in the soil. The DMP and Ds were COT-dependent because values of both increase or decrease depending on the soil layer. When higher the soil layer there was an increase in carbon stock.

title: Plasma Renin in Women Using and not Using Combined Oral Contraceptive

description: Abstract Backgroud: Recent studies show that women on combined oral contraceptives (COC) present abnormal fasting lipid profile, increased postprandial lipemia, plasma C-reactive protein (CRP) and blood pressure (BP) compared to women not on combined oral contraceptives. Plasma renin is one of the factors responsible for abnormal BP. Objectives: To assess plasma renin levels in women using or not using COC, the correlation between renin and CRP, as well as divergences in lipid profile. Methods: A cross-sectional study with apparently healthy women aged 20 to 30, eutrophic, irregularly active, and with fasting triglycerides &lt; 150 mg/dL. The sample was stratified into two groups: the No Combined Oral Contraceptive Group (NCOCG), comprised of women who did not use any type of hormone contraceptive, and the Combined Oral Contraceptive Group (COCG) comprised of women on low-dose COC for at least one year. After a 12-hour fast, 5 ml of blood was collected for renin dosing and PCR. Data were analyzed by the t-Test and bidirectional Mann-Whitney Test, both with significance &lt; 0.05. Results: We evaluated 44 women equally distributed between the groups, age 23 ± 1.2 years, BMI 21.0 ± 3.2 kg/m2. Median and interquartile deviation of renin in the NCOCG and the COCG were, respectively, 0.5 (0.1-1.0) and 3.0 (2-6) (p &lt; 0.01). A positive correlation between PCR and renin (p &lt; 0.01 and r = 0.68) was found. Conclusion: The plasma renin levels of women using COC were higher, with a strong correlation with CRP.

title: Assessing geologic model uncertainty - a case study comparing methods

description: Abstract Evaluating mineral resources requires the prior delimitation of geologically homogeneous stationary domains. The knowledge about the ore genesis and geological processes involved are translated into three dimensional models, essential for planning the production and decision-making. The mineral industry usually considers grade uncertainty for resource evaluation; however, uncertainty related to the geological boundaries are often neglected. This uncertainty, related to the location of the boundary between distinct geological domains can be one of the major sources of uncertainty in a mineral project, and should be assessed due to its potential impact on the ore tonnage, and consequently, on enterprise profitability. This study aims at presenting three different methodologies capable of generating multiple geomodel realizations and thus, assessing uncertainty. A real dataset with high geological complexity is used to illustrate the methodology. The results are compared to a deterministic model used as a reference scenario.

title: Chemical composition and fatty acids profile of chocolates produced with different cocoa (Theobroma cacao L.) cultivars

description: Abstract The objective of the present study was to characterize the physicochemical composition and to quantify the fatty acids of chocolates produced from different cocoa varieties (Theobroma cacao L.) cultivated in the Southern Region of Bahia. Nine samples of monovarietal chocolates were evaluated, according to their physical, thermal and fatty acid profile. The results were subjected to tests of variance and multivariate statistics. The chocolates PH16 and TSH1188 presented higher melting point. It was possible to identify a linear correlation between the fat content of the chocolates and the break force parameter. The chocolates showed higher concentration of saturated fatty acids, mainly palmitic acid (16:0) and stearic acid (18:0), followed by the unsaturated fatty acids among which oleic acid (18:1n-9) and linoleic acid (18:6) were predominant. The principal component analysis allowed to discriminate the different varieties of chocolate according to the profile of fatty acids. The thermogravimetric analysis of the samples showed a similar profile. The differences found in the samples of chocolates were attributed to factors such as the fruit maturation process, the cocoa variety and to which they were subjected during processing.

title: Stability evaluation of juçara, banana and strawberry pasteurized smoothie during storage

description: Abstract The objective of this work was to evaluate the effect of storage time and temperature on main characteristics of a juçara (20%), banana (40%) and strawberry (40%) pasteurized smoothie. The pasteurized smoothie was stored at 7 °C and 25 °C for 90 days. At both temperatures there was degradation of the smoothie anthocyanins, which, as expected, was more drastic in storage at room temperature, impacting also the instrumental color of the product. The microbiological quality of the product was assured at both storage temperatures, showing absence of Salmonella spp. and counting for thermotolerant coliforms &lt;3 MPN.g-1, which is in accordance to Brazilian legislation. Under refrigeration, the smoothie had good sensory acceptance with scores higher than 6 even after three months of storage. Taking into account the high preservation of the bioactive compounds, mainly of the anthocyanins, the juçara, banana and strawberry pasteurized smoothie can be stored for 90 days under refrigeration temperature (7 °C).
