title: Recombinant human growth hormone (rhGH) incorporated into biodegradable polymer scaffolds

description: AbstractObjectiveIncorporate recombinant human growth hormone in a biodegradable polymer (PLGA).Material and methodThe arrays were fabricated by solvent evaporation technique. A mixture of polymer (poly lactic glycolic acid) and recombinant human growth (Saizen® Merck Serono SA Aubonne, Switzerland) was performed hormone. This mixture was poured into circular molds silicone 01cm in diameter and about 02mm thick, and carried into a drying chamber for evaporation of solvent for 48 hours. After this period, the matrices were immersed in PBS and passed through a constant temperature bath (test for hydrolytic degradation) in vitro, at a temperature of 37°C. The samples were removed from the bath in the range of 01, 02, 03, 04, 07, 10, 14 days. Mass loss, pH and concentration of hormone released as a function of time was measured.ResultThe concentration of hormone released versus time was increased until the third day. On the fourth day had a fall and on the seventh day there have been increased hormone released by the tenth day, the fourteenth day was falling again. The pH had a sharp drop from 7.4 to 3.2 on the first day and keeping a small drop until the fourteenth day. The mass loss was a gradual loss in relation to time as was to be expected.ConclusionPLGA is a good biomaterial for making breeders of growth hormone. It has proved possible to incorporate the rhGH in the array so as to then develop a bone substitute.

title: BIOLOGICAL MATURATION AND SEDENTARY BEHAVIOR IN CHILDREN AND ADOLESCENTS: A SYSTEMATIC REVIEW

description: ABSTRACT The aim of this study was to analyze the association between biological maturation and sedentary behavior in children and adolescents. We performed a systematic review in May 2015 in the PubMed/MEDLINE, SportDiscus, Web of Science and LILACS databases, with no restriction of time. A total of 294 potentially relevant articles were identified and seven met the inclusion criteria. A direct association was identified between sedentary behavior and tempo of biological maturation. Sedentary behavior appears to increase with advancing chronological and biological age in both genders. Regarding the relationship between sedentary behavior and timing of biological maturation, greater sedentary behavior was observed in early maturing boys and girls. However, in some studies, this relationship varied between genders. Biological maturation appears to contribute to the increase in sedentary behavior in children and adolescents.

title: Quality of water used by beach kiosks

description: Abstract This study evaluated the sanitary conditions and the microbiological quality of the water used by beach kiosks. Data was collected through direct observation, using a checklist with such items as water source, disinfection treatment before use, frequency of water container sanitation, microbiological quality of water, existence of sanitary license and records of the last inspection by health authorities. Water samples were collected in labeled, sterilized containers from 10 beach kiosks. The plate technique in depth in standard agar was used for counting heterotrophic bacteria and the results were expressed in CFU/mL. The most-probable number test was used to evaluate coliforms (coliforms at 35°C and 45°C) and the results were expressed in NMP/100 mL. It was observed that 70% of the kiosks used only water from the public supply and one of the establishments operated without a sanitary license. Of the samples collected, 30% had a total bacterial count above 500 CFU/mL. No presence of coliforms and E. coli. was detected in the samples analyzed. While the results were satisfactory, the study reinforced the need to monitor water quality as a strategy to prevent risks to consumers.

title: Waterborne infectious and parasitic diseases and respiratory diseases in an industrial area, Northern Brazil

description: Abstract Barcarena city is an important industrial hub that has been subjected to environmental incidents in recent years. The present study reports the morbidity profile of waterborne infectious and parasitic diseases (IPD) and respiratory diseases (RD) among individuals living in Barcarena city is from 2008 to 2012. The survey was conducted with secondary data on mortality and hospital admission rates obtained from the Computer Department of the Ministry of Health - DATASUS. The average mortality rate (AM) to IPD indicated 0.37 deaths per 1000 inhabitants. The age group mostly represented in cases of hospitalizations caused by IPD was 0-5 years. The average coefficient of incidence due to this cause in the case of age group below five years of age was around 31.8/100,000 inhabitants. Regarding DR, children aged between 0 and 14 years are apparently the most exposed ones, corresponding to 62.85% of the cases, and the elderly over 60 years of age are the most exposed, with 15.16% of the cases. Incidence and mortality rates due to DR were in the order of 39/100,000 inhabitants. The health indicators studied warn that populations in Barcarena are under possible risks to health and suggest that more specific studies on quantitative and qualitative possible environmental contamination in the region are still needed.

title: Unscented Kalman Filter for Determination of Spacecraft Attitude Using Different Attitude Parameterizations and Real Data

description: ABSTRACT The non-linear estimators are certainly the most important algorithms applied to real problems, especially those involving the attitude estimation of spacecraft. The purpose of this paper was to use real data of sensors to analyze the behavior of Unscented Kalman Filter (UKF) in attitude estimation problems when it is represented in different ways and compare it with the standard estimator for non-linear estimation problems. The robustness of the estimation was performed when this was subjected to imprecise initial conditions. The attitude parametrization was described in Euler angles, quaternion and quaternion incremental. The satellite China-Brazil Earth Resources Satellite and measurements provided by the Satellite Control Center of the Instituto Nacional de Pesquisas Espaciais were considered in the study. The results indicate that the behaviors for both estimators were equivalent for such parameterizations under the same conditions. However, comparing the Unscented Kalman Filter with the standard filter for non-linear systems, Extended Kalman Filter (EKF), it was observed that, in the presence of inaccurate initial conditions, the Unscented Kalman Filter presented a fast convergence whereas Extended Kalman Filter had problems and only converged later on.

title: CORN DEVELOPMENT AND PRODUCTION IN FUNCTION OF SOURCES OF NITROGEN FERTILIZERS AND DOSES

description: ABSTRACT Nitrogen (N) is one of the nutrients that have the most significant effect on corn grain productivity increase. In order to evaluate the effect of sources of N topdressing and doses in the grown corn culture, in a conventional till system, it was installed an experiment in the city of Urutaí, Goiás, in the 2012/13 crop, in clayey textured Red Latosol. The experimental design was a randomized complete block design with four replications, with the treatments arranged in a factorial 3 x 5, consisting of three sources (coated urea, urea and ammonium sulfate) and five doses (0, 60, 120, 180 and 240 kg ha-1) of N, topdressing, applied in the surface and in a single dose, when the corn plants were in V4 stage. The hybrid used was the P3646H. We evaluated the following characters: stem diameter, plant height, height of ear insertion, leaf N, number of ears per plant, ear length, number of rows per ear, number of grains per row, 100 grains mass and grain productivity. All characters have a response to nitrogen fertilization and only the height of ear insertion showed no significant difference between sources. The source coated urea showed the best results, indicating that its use may be compensatory, especially in favorable conditions for the NH3 volatilization, as the application of high doses of N in the surface.

title: KNOWLEDGE PRODUCTION ON CONTINUOUS PROFESSIONAL LEARNING OF PHYSICAL EDUCATION TEACHERS: AN ANALYSIS BETWEEN BRAZILIAN AND INTERNATIONAL STUDIES

description: ABSTRACT This article analyzes knowledge production on continued training of physical education teachers in the Education Resources Information Center (ERIC) database and a collection of 14 Brazilian journals. The goal is to provide an overview on scientific production and discuss the search options adopted by researchers, identifying developments and trends. There has been a transition in the 15-year period analyzed (2000-2014) and a prevalence of studies emphasizing the participants history. There was a predominance of phenomenological-hermeneutical studies regarding the epistemology and of qualitative studies regarding the research methods. Our data suggest that there is room to investigate the continued professional training, perceiving teachers as researchers of their practice and transforming agents of their reality.

title: Urban solid waste challenges in the BRICS countries: a systematic literature review

description: Abstract Urban Solid Waste Management (USWM) is a worldwide challenge. The problems faced are even greater due to the disproportional increase of Urban Solid Waste (USW) generation in volume, especially in a context of increased urbanization, population growth and economic globalization in the BRICS countries (Brazil, Russia, India, China and South Africa). In this context, the objective of this work is to analyze the status of MSW management in the BRICS countries, as well as to promote an exchange of experience and management strategies, pointing out possible ways to improve USWM systems that have to be adapted to each local reality. Focusing on this, a systematic literature revision was carried out through a bibliometric analysis. Results showed that the management system of these BRICS countries does not possess well-developed structures. The collection stage is quite often inefficient, the solid waste being stored in inappropriate ways and also disposed of in irregular locations. The participation of the informal sector is a trademark characteristic in USWM for BRICS countries, highlighting the need to integrate and formalize these activities for USW collection. Due to the high organic fraction, it is known that composting offers advantages as a way to promote a better use of organic waste and also as a means of reducing the amount of waste sent to sanitary landfills. Finally, with a better knowledge about solid waste generation and decentralization of the offered services, the decision makers will be able to successfully provide this essential public service.

title: Seasonal and spatial evaluation of the surface water quality in the Longá river watershed, Piauí, Brazil

description: Abstract This article evaluates the quality of the surface waters in the Longá River watershed in the State of Piauí, Brazil. Seven points were monitored, based on their proximity to meteorological stations and accessibility, to obtain better spatial and land-use characterizations of the watershed. Water samples were collected monthly (01/2015-12/2015). The variables temperature, pH, turbidity, electrical conductivity, total solids, total phosphorus, nitrate, dissolved oxygen, biochemical oxygen demand (BOD) and Escherichia coli (E. coli) were measured. The results were evaluated individually and compared to Brazilian standards for Class 2 fresh waters, according to the National Environment Council’s (CONAMA) Resolution 357/2005. The data were evaluated using multivariate analyses (clustering and principal component analysis - PCA). E. coli, pH, turbidity, nitrate, BOD, and electrical conductivity varied between the two periods analyzed (dry and rainy). The BOD and E. coli variants were noncompliant with the CONAMA standards at urban points P2, P3, and P5, because of nonpoint source pollution (NPS) during the rainy season. Clustering showed a spatial trend, presenting two distinct groups (rural and urban). PCA identified four main components that explained a 58.64% change in the data. Component 1 (CP1) reflected a contribution of pollutants related to NPS from agricultural and urban areas, in addition to environmental factors. CP2 was strongly associated with pollution, especially by untreated sewage releases. The other CPs also reflect pressures from anthropogenic activities on the water bodies.
