title: Study of Aramid Fiber/Polychloroprene Recycling Process by Thermal Degradation

description: ABSTRACT Aramid fiber is an important polymer applied as reinforcement in high-performance composites, which, due its exceptional properties, becomes an excellent impact absorption material. It has been broadly utilized in aeronautic industry and ballistic protection. In aircrafts, it is mainly used in secondary structures, such as fairings, floor panels, and bullet proof structures in helicopters, whereas, in ballistic protection industry, it is applied in automotive armor and bullet proof vest. Under environmental perspective, it is worrying the development and application of composites, which generate proportional discards of these materials, whether originated from manufacturing process, spare parts or end of life cycle. High-performance composite materials like those using aramid fiber are generally difficult to recycle due to their properties and the difficulty for the separation of the components, making their recycling economically unviable. From the characteristics of composite materials and environmental viewpoint, this paper presents a new aramid fiber recycling process. The main objective of this research was to study different recycling methods in aramid fibers/Neoprene® composites. To promote the Neoprene® degradation, it was used a pyrolysis oven with controlled atmosphere and CO2 injection. For the degraded separation, it was designed a mechanical washing machine in which the most degraded separation occurred. To complete the materials separation, it was employed a manual cleaning process, and, at least to prove the efficacy of the process, it was applied a tensile test in the yarns.

title: An investigative case study at local hospital into the current reliability of blood pressure sphygmomanometers

description: Abstract Introduction Arterial Blood Pressure is a significant indicator of the current health condition of an individual. The correct detection of hypertension is essential, where this health problem is considered as one of the greatest health risks factors that affect the heart and circulatory system. This paper presents the importance of the application of metrological criteria for the diagnosis of hypertension using a sphygmomanometer aneroid. Methods 72 mechanical aneroid sphygmomanometers were calibrated using a standard manometer and the indication error, hysteresis, air leakage and rapid exhaust were determined; readings of these sphygmomanometers were compared to a properly calibrated and adjusted aneroid sphygmomanometer to carry out pressure measurements as those made during the hypertension diagnosis; the uncertainty of measurement associated with the sphygmomanometers calibration, and pressure values was assessed according to the recommendations of the Guide to the Expression of Uncertainty in Measurement, defined by the Joint Committee for Guides in Metrology. Results The results obtained have shown that about 61% of the evaluated aneroid sphygmomanometers did not meet the specifications. The variable that most contributed to the final calibration uncertainty was the hysteresis of the standard manometer, with 53% of contribution, followed by the sphygmomanometer resolution with 27%. Conclusion The periodic verifications are essential to evaluate the performance of these devices. It was shown that uncertainty of measurement influences the final diagnosis of hypertension and the application of metrological criteria can increase the reliability of the final diagnosis.

title: NITRATE AND POTASSIUM DYNAMICS IN PROFILES OF SOILS CULTIVATED WITH FERTIGATED SUGARCANE CROPS

description: ABSTRACT The objective of this study was to evaluate the distribution of NO3 - and K+ in the profile of soils cultivated with sugarcane crops, after application of different nitrogen (N) and potassium (K2O) rates via subsurface drip fertigation, in Teresina, PI, Brazil. The experiment was conducted at the experimental area of Embrapa Meio-Norte, using a randomized block design with four replications. The treatments were arranged in split plots, with N+K2O rates (60+120, 180+120, 120+60, 120+180, and 120+120 kg ha-1 of N + K2O, respectively) in the plots, and soil layers (0.0-0.2, 0.2-0.4, and 0.4-0.6 m), for quantification of NO3- and K+ concentrations in the soil, in the subplots. The soil of the experimental area was a Typic Hapludult of sandy-loam texture. The distribution of nitrate (NO3-) and potassium (K+) in the soil layers after the N+K2O applications were evaluated. The NO3- and K+ concentrations in soils under sugarcane crops in the plant crop cycle is higher at the beginning and at the end of the cycle, respectively. The NO3 - and K+ concentrations in the soil solution are dependent on the evaluation time, soil layer, and N and K2O rates applied via fertigation. The highest concentrations of NO3- (264 mg L-1) and K+ (377 ppm) were found in the 0.0-0.2 m soil layer. No leaching of NO3- or K+ to deepest soil layers (&gt;0.4 m) was found.

title: Multi-criteria analysis for site selection for the reuse of reclaimed water and biosolids

description: Low pH soils with insufficient organic matter can benefit from the application of reclaimed water (RW) and biosolids. The presence of nutrients also aids plant growth. This paper presents the results of two integrated research studies, both carried out in the Beira Interior Region (Covilhã, Portugal); one used RW for irrigation, the other applied paper mill sludge to agricultural land. In both cases, multiple criteria based on GIS tools were used for site selection. In the first study, the characteristics of RW analyzed over 2 years were found suitable for crop irrigation. The RW had moderate organic content, low electrical conductivity (CE), high nutrient content (N, P), and low concentrations of nitrate, metals and phytotoxic elements (Al, B, Cl and Na). The multi-criteria analysis was carried out taking into account environmental, technical and economic criteria and a suitable area of 30.5 ha was found for RW irrigation. In the second work, the paper mill sludge was considered suitable for application to agricultural land. Its concentrations of N, P and heavy metals did not a present risk for soil contamination and were suitable for soil improvement and crop production. A multi-criteria analysis based on similar criteria was conducted and a suitable area of 253 ha was found for sludge application.

title: The Moderating Effect of the Sector's Level of Concentration on the Relationship Between Balance Sheet Composition and the Firm's Competitive Advantage

description: ABSTRACT This paper investigates the relationship between the competitive advantage and balance sheet composition of the firm, based on metrics contained in the structure of financial statements, from endogenous origin (firm's balance sheet composition) or exogenous (level of sector concentration). In addition, we perform tests in order to verify whether the exogenous characteristics moderate the relation between endogenous characteristics and the firm's operational performance. We selected data from the Economatica® database, a Brazilian company specialized in information for the capital market. We based the tests on the hierarchical model approach with repeated measures involving serial and nested regressions, estimated by maximum likelihood. The test results suggest that (i) the firm's idiosyncratic features have greater explanatory capability for the firm's performance than the industry features; (ii) the relation between firm idiosyncratic resources and firm performance are sensitive to industry characteristics.

title: Health, work, and development: agribusiness and accidents in a state in the Brazilian Amazon region

description: Abstract Introduction Mato Grosso is one of the Brazilian states with the highest agribusiness growth, which is accompanied by deforestation and an increase in occupational injuries. Objective To assess some factors associated with agribusiness-related severe occupational injuries in Mato Grosso. Method Occupational injury notifications were provided by the System of Information of Notifiable Injuries (SINAN). The production sectors, considered the dependent variables, were classified as forestry/wood industry, animal husbandry, and plant husbandry. Some sociodemographic, care, and type of injury-related variables were selected and considered the independent variables. We conducted a spatial analysis of the density of occupational injury. The associations were identified by calculating the proportion ratio (PR) by the chi-square test and considered significant when p-value &lt; 0.05. Results and conclusion The highest rates of severe occupational injuries occurred in municipalities with intense plant and animal husbandry, and forestry/wood industry activities. In plant husbandry severe occupational injuries were more common in men, adults, non-whites, illiterates, and rural areas. However, in animal husbandry and forestry/wood industry, severe occupational injuries were more common in adults, and full recoveries were less frequent.

title: More Doctors Program: mapping and analysis of academic production in the period 2013-2016 in Brazil

description: ABSTRACT With the purpose of strengthening Primary Health Care (PHC) in Brazil, the More Doctors Program (PMM) was created in 2013, structured around three strategic axes. This study aimed to analyze the scientific production in the PMM, identifying the relevance of the studies and their effects to the policy and elaborating a synthesis of the main themes. The search was carried out in the Regional Portal of the Virtual Health Library (VHL) and in the Knowledge Platform of the PMM, with 409 documents being identified. After exclusion criteria, 47 scientific articles were selected. The results showed that 55% of studies focused on the 'emergency doctors provision' axis, 32% presented general policy assessments, 4% focused on provision/infrastructure and only 9% focused on training. Of the articles selected, 22 were considered of high and medium relevance. Furthermore, 32 publications identified the effects of the PMM (29 identified positive effects; and, in only 3, positive and negative effects were equivalent). In the thematic analysis, the following stand out: equity, efficacy, professional training, PMM implementation, work practices and processes, media approach and PMM political analysis. Of an extensive nature, the analyzes pointed out clues about the directionality of the Program, its weaknesses and needs that are required for a research agenda for the coming years.
