title: Spatial Distribution of Temporal Metadata and Spatial Metadata Quality of Santa Catarina State Weather Stations for Climatology

description: Abstract The objective of this paper was to evaluate the temporal (start date and end date) and spatial metadata (latitude, longitude and altitude) of the Santa Catarina state weather stations, based on the recommendations of the World Meteorological Organization - WMO for climate studies. Metadata of the weather stations maintained by the Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri until 06/30/2017 were evaluated. The Santa Catarina state has few weather stations with historical series above the minimum period of 30 years, indicated by WMO to carry out climatic studies. The spatial distribution of weather stations are not in accordance with the pattern of territorial representation established by WMO. Despite advances in the weather stations network management process, the state of Santa Catarina needs to comply with all recommendations of WMO, to ensure the quality of the temporal and spatial metadata of climate monitoring stations.

title: Nanocomposite Films Based on Flaxseed Gum and Cellulose Nanocrystals

description: Flaxseed gum (FG)-based films were developed with the addition of glycerol as a plasticizer and glutaraldehyde as a crosslinking agent. HCl was added to improve crosslinking and decrease the hydrophilicity of the matrix. Different cellulose nanocrystal (CN) amounts were used as reinforcements in the optimum FG formulation. The crosslinking process at pH 3.5 led to a lower solubility of FG in water (from 100% to 53%) and an increase in thermal stability (from 160 ºC to 209 ºC). FTIR analysis confirmed a reduction in the -OH band due to crosslinking between the hydroxyl groups of FG. A diffuse diffraction pattern was observed for all FG films. The addition of 4% w/w of CN contributed to reduction of water solubility (from 53% to 20.8%) and absorption (from 21.9% to 6.8%). Finally, an improvement was observed in the tensile mechanical properties in the nanocomposites, showing satisfactory results for the proposed formulations, mainly with 8% w/w of CN added to the matrix. Overall, this study demonstrated that FG/CN nanocomposites are promising materials to be use as a sustainable biopolymer for application as bioplastics.

title: The contributions of the Social and Human Sciences in the field of Collective Health: twenty years of the journal Interface

description: We present a discussion about the bibliographic production in Social and Human Sciences in Health (SHSH) published by the journal Interface in the last twenty years (1997-2017). We aim to describe the legitimation process of the SHSH by disseminating theoretical and methodological knowledge and specific themes within the Brazilian scientific production. All the publications of the period were consulted and 216 articles identified with the SHSH were selected. The analysis resulted in categories that highlighted the following themes: mental health, aging, infectious diseases, gender, reproductive health, and theoretical-conceptual. The combination of the themes with current problems of the Brazilian society reveals authors as protagonists of studies that have social relevance and political commitment to transformations and changes occurring both in health care and in public policies.

title: Thermal Behavior of Pyrite in the CO2 and N2 Atmosphere for Obtaining Pyrrhotite: A Magnetic Material

description: In the southern of Brazil the coal is composed of a large amount of pyrite (FeS2), an environmental problem for this region because the pyrite turns a waste. This work investigated the behavior of pyrite in CO2 and N2 atmospheres, aiming to identify better thermal treatment conditions of the pyrite waste that favor obtaining a material with magnetic properties. The results show that the samples treated in both conditions presented hysteresis and some magnetic properties. The best results were obtained from N2 because it is an inert gas, avoiding the pyrite oxidation and, consequently, favoring a major amount of pyrrhotite. The X-ray diffraction analyses showed that partial thermal decomposition of the pyrite occurs at 600 ºC. The total decomposition was reached at 800 oC and the pyrrhotite phase was obtained. Such findings are relative new and can help enhance the utilization of pyrite, contributing to the environmental sustainability of the coal mining industry.

title: Fungal endophytes of Panicum maximum and Pennisetum purpureum: isolation, identification, and determination of antifungal potential

description: ABSTRACT This study aimed to isolate and identify endophytic fungi from the forage grass P. maximum and evaluate their ability to inhibit the growth of plant pathogenic fungi. One sample from P. purpureum grass was also included. Surface disinfected stem fragments were used for endophytic fungal isolation. One hundred and twenty-six endophytic fungi were isolated, of which 118 were from P. maximum and eight from P. purpureum. Morphological characteristics and internal transcribed spacer (ITS) and 18S (NS) sequence comparisons identified most isolated endophytic fungi as belonging to the phylum Ascomycota, with Sarocladium being the dominant genus. The isolates were subjected to in vitro antagonism tests against pathogenic fungi, and 31 endophytic fungi inhibited the growth of Bipolaris maydis, Penicillium expansum, and Sclerotinia minor. The results expand our knowledge of the diversity of endophytes associated with tropical grasses and suggest that they may represent new sources of antifungal metabolites for biocontrol and biotechnological purposes.

title: Carcass characteristics and meat quality of broilers fed with crude glycerin originated from palm oil and wasted vegetable oil in diets

description: ABSTRACT. A study was conducted to evaluate the effect of crude glycerin on slaughter weight and carcass characteristics of broilers. Total of 180 male Ross - 308 day old chicks were allocated to 3 treatments with 4 replicates in a completely randomized design. The dietary treatments were: diet without crude glycerin inclusion (T1), diet with 5% crude glycerin inclusion from waste vegetable oil (T2), and diet with 5% crude glycerin inclusion from palm oil (T3). On day 42, twenty chickens per treatment were randomly sampled and slaughtered to determine the carcass characteristics. From the study, both crude glycerins did not give any effect on the slaughter weight and carcass characteristics, but broilers received crude glycerin had higher abdominal fat (p &lt; 0.001) than control. Drip loss, cooking loss, pH, and meat color were not influenced by both types of crude glycerin, however, the skin color was significantly affected by palm oil crude glycerin inclusion (p &lt; 0.05). Furthermore, meat from broilers with crude glycerin had higher lipid oxidation than control (p &lt; 0.001). In conclusion, crude glycerins could be added in broiler’s diet, however its effect on increasing fat and lipid oxidation must be taken into concern.

title: Hospital School Assistance: Ways Throughout Scientific and Legal Bases

description: ABSTRACT: Hospital school assistance has been regulated by its own legislation for almost two decades. Thus, the objective of this paper was to analyze the scientific and legal bases of this subject using a comparative study between the papers published in the Brazilian Journal of Special Education that deal specifically with this theme, the results of national meetings promoted, the biannual newsletters disseminated and some recent academic papers related to the topic. The research technique used was the bibliographical and documentary research, and the proposed analysis was the content analysis. The results point out that this area of knowledge was based on research that at the time, even if incipient, guided what would be delimited as the essence of school assistance to the patient. Despite the increase in the supply of this type of education, it is not necessarily restricted to schooling in the hospital, demonstrating a different understanding of what the legal regulations for this service prescribe. The national meetings continue the discussion, but they are also projected for themes that do not directly dialogue with the proposal of schooling in the hospital, but with other aspects related to the life of the patient. Biannual newsletters focus more specifically on this area. They disseminate studies, legislation, relevant events, and bring the interested people in this educational modality closer. Considering also the reality of this schooling in other countries, it is possible to affirm that the recognition and respect of the right to schooling of the patient make this service be offered with the jurisprudence and the quality necessary for the fulfillment of its attributions with the sick pupils.

title: Polyunsaturated fatty acids in the blood of pregnant women who have consumed omega-3 supplements and golden flaxseed oil

description: Abstract: The objective of this study was to evaluate serum levels of docosahexaenoic (DHA) and eicosapentaenoic (EPA) in the blood of pregnant women who received omega 3 supplementation through ingestion of capsules or linseed oil. Comparing the groups, there was a higher level for flax oil for AA and DHA contents, indicating that supplementation favored the metabolic pathway of both eicosanoid intermediates formation.

title: Risk factors for substance use: perception of student leaders

description: ABSTRACT Objective: to analyze the perceptions of student leaders of the undergraduate course in Nursing about the motivations and/or risk factors for substance use in the university environment. Method: qualitative, transversal, descriptive study developed in a university campus in the state of São Paulo. Thirty members of associations affiliated with the course in Nursing participated. A questionnaire and a semi-structured interview were used, and the information was subjected to content analysis. Results: the influence of the social environment was the central element in the results. The circumstances of the context, some conditions that favor the use of substances and the students’ expectations regarding their use were perceived as risk factors, among which the influence of friends (96%), curiosity and search for fun (93%) stood out. Final considerations: alternatives in the university context, in conjunction with student leaders, aimed at reducing the exposure to physical and psychological suffering, constitute important resources to prevent substance abuse.

title: Synthesis and Antibacterial Evaluation of 3,5-Diaryl-1,2,4-oxadiazole Derivatives

description: This manuscript reports the synthesis of twenty 3,5-diaryl-1,2,4-oxadiazole derivatives, nine of which are novel compounds. The amidoxime reaction with acyl chlorides obtained from substituted benzoic acids was used. All compounds were tested against five standard (American Type Culture Collection (ATCC)) bacteria: Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis, Proteus mirabilis and Staphylococcus aureus. Screening assays were carried out using agar-diffusion technique, in which 100 µM heterocyclic compounds solutions (20% dimethylsulfoxide/water) were employed. The minimum inhibitory concentrations (MIC) of the active compounds were determined by serial dilutions at decreasing concentrations in microtiter plates. The nitrated derivatives gave the best test results, where MIC = 60 µM (E. coli) was the lowest value found for an ortho-nitrated derivative. The activity of these compounds possibly involves a mechanism via free radicals. S. aureus and P. aeruginosa were resistant to all compounds.
