title: Microhardness in pressing layers of prefabricated modified acrylic resin teeth

description: OBJECTIVE: The aim of this study was to evaluate the microhardness in pressing layers of prefabricated modified acrylic resin teeth. METHODS: Lower first molar teeth with two (Biotone(r) IPN and Bioform(r)) or three pressing layers (Artiplus(r), Trilux(r) Eurovipi, and Natusdent(r)) were hemisected in a bucco-lingual plane and embedded in a self-curing acrylic resin (n =10). Specimens were then ground flat and polished using 400, 600 and 1200 aluminium oxide paper in a rotatory polisher. In each pressing layer, microhardness was measured using a Knoop indenter in three different locations spaced 300 µm apart under a 10-g load, applied for 5 sec. RESULTS: Analysis of variance and Tukey's tests demonstrated that there was no difference in microhardness in the first layer of the teeth analyzed (p = 0.355), whereas in the second layer, the brand Artiplus(r) showed higher values when compared to the brand Natusdent(r) (p = 0.018). For the third layer, the brands Artiplus(r) and Trilux(r) Eurovipi revealed higher microhardness when compared to Natusdent(r) teeth (p &lt; 0.001). CONCLUSION: For the outer most superficial layer of the artificial teeth, the microhardness of the different brands was similar, while differences were noted for the second and third layers among the artificial teeth, with Artiplus(r) teeth showing higher microhardness than Natusdent(r).

title: Maternal deaths due to abortion among adolescents in Piauí, Brazil

description: ABSTRACT This article analyzes maternal deaths of adolescents in Piauí and describes the stories of those who died due to induced abortion between 2008 and 2013. The study was conducted in two stages. The first, quantitative, obtained demographic data and basic causes of deaths from the Mortality Information System. In the second, qualitative, the mothers of the adolescents were interviewed. Adolescents’ deaths accounted for 17.2% (50 cases) of total maternal deaths. The majority of the adolescents lived in inner cities (78%) and was black (70%). The causes of death were hypertensive disorders (28%), puerperal infection (16%), hemorrhage (12%), thromboembolism (12%) and abortion (10%). The use of medication occurred in all cases of abortion, with abundant bleeding and pelvic pain being the main reasons for seeking hospital care. There was delay in the diagnosis and appropriate treatment of abortion complications, which may have contributed to the death of the adolescents. Maternal deaths among adolescents were mostly caused by conditions considered preventable. The stories of young women who died of abortion complications have highlighted the need for better-qualified health care, as well as laws and public policies that protect women who decide to terminate their pregnancies.

title: Primary hyperparathyroidism in developing world: a systematic review on the changing clinical profile of the disease

description: ABSTRACT While the developed world is focusing on laying guidelines for selecting out cases of Asymptomatic primary hyperparathyroidism (PHPT) for surgical intervention and promoting minimal access surgery, the developing world is observing a change in disease spectrum from advanced symptomatic to lesser degree of symptomatic disease and not many with associated Vitamin D deficiency. Few studies from the developing countries of the world have focused on the changing clinical spectrum of PHPT. Objective of this study is to review the changing profile of PHPT in developing world. A systematic literature search was done in December 2017 focussing on publications from the developing world. All studies pertaining to the epidemiology of PHPT published after 1st January 2000 and published in English language were included for analysis. Most of the studies published from developing countries report a predominance of symptomatic disease (79.6% of all included patients) with musculoskeletal disease present in the majority of patients (52.9%). The combined mean serum total calcium (11.9 ± 1.4 mg/dL), serum PTH (668.6 ± 539 pg/mL), serum alkaline phoshpatase (619 ± 826.9 IU/L) and weight of excised parathyroid glands (4.4 ± 3.8 grams) are much higher than those reported from the western studies. Despite this, we found that there is a distinct trend towards a milder form of disease presentation and biochemical profile noticeable in more recent times. Although there is a striking difference in all aspects of PHPT disease epidemiology, clinical presentation and biochemical profile of developing and developed countries, there is a distinct trend towards a milder form of disease presentation and biochemical profile in more recent times.

title: Wood Sustainability Assessment Through ISMAS Tool

description: ABSTRACT This research aimed to assess the level of sustainability of the wood used in construction, based on the previously established criteria obtained with the ISMAS tool - Tool for Selecting Most Sustainable Materials, which methodology specifically considers aspects related to “economy of raw materials” and “generation and waste management” in evaluation procedures. The tool displays the following rating scale for the possible results: very low, low, medium, high and very high. The methodology used to obtain the results was established from an instrument test, involving architects from the state of Espírito Santo (Brazil). The results showed a “high” sustainability index of the wood, contradicting the initial hypothesis that the material would reach the “very high” level. This result suggests the maturity of the sustainable wood concept, which currently relates only to the renewable criteria. The review by ISMAS demonstrated the necessity of using other criteria.

title: CBRN events management and the use of the Hysplit model: an integrative literature review

description: ABSTRACT The potential risk of exposure of populations to Chemical, Biological, Radioactive and Nuclear agents (CBRN), either by intentional causes or not, is a matter of national security and demands a constant improvement in its management. The models of atmospheric dispersion have been gaining prominence as a tool to support the management of risks to CBRN agents. The objective of this research was to identify and evaluate studies that used the Hysplit model in the context of CBRN events. For this purpose, an integrative literature review of published articles was conducted between 2014 and 2018, from the PubMed, Scopus, Web of Science and Lilacs databases. The analysis of the selected articles revealed the potential of the Hysplit model, as a mathematical model, to understand the transport, dispersion and deposition of CBRN threats released into the atmosphere. The data produced by the simulations generated by this code can reveal which areas will be potentially impacted in a given event or the region of origin of elements dispersed in the air. In addition, Hysplit can be aggregated as a decisions support tool in the different phases of CBRN event management.

title: Patterns of Natural Regeneration in the Region of “Mar de Morros”, Pinheiral-RJ

description: ABSTRACT The Atlantic Forest is the brazilian ecosystem that is subjected to stronger environmental degradation processes, yet in some environments the natural regeneration process can be observed. Thus, the aim of this study was to evaluate the pattern of natural regeneration of forest fragments in the “Médio Vale Paraíba do Sul” as the topographic factors and to identify potential areas of regeneration. The mapping of forest fragments were obtained from images of the Thematic Mapper sensor (1994 and 2011). For topographical factors, the IBGE topographic maps were used. The natural regeneration process in the study area is influenced by topographical factors and occurs mainly in environments with a flat surface, steepness ranging from wavy corrugated strong, strand orientation ranging from SE (southeast) SW (southwest) and global solar radiation between 1.500.000 and 1.700.000 Watts. In sub-basin Cachimbal stream, favorable environments natural regeneration are not sufficient for sub-basin has restored its original forest cover, it represents only 1.2% of the watershed area, which refers to the need of human intervention.

title: Effect of Thermal Treatment With Soybean Oil on Wood Pinus

description: ABSTRACT This study aimed to evaluate the influence of heat treatment on soybean oil with some physical properties of Pinus sp wood, being evaluated the dimensional variation, density, warping and cracking in samples with 5 mm and 20 mm thicknesses. The samples were submitted to heat treatment at a temperature of 80 °C to 160 °C, for 20 and 40 minutes, with and without subsequent immersion in cold oil. Comparisons were made with control samples, to 12% moisture content. The results demonstrated that the factors of greater effect of the thermal treatment with soybean oil on the properties were: high-temperature heat treatment (160 °C); lower initial thickness (5 mm); longer treatment (40 minutes) and immersion in cold oil after the heat treatment. The effects of the heat treatment associated with immersion in cold oil resulted in lower shrinkage and warp and in the increase in density values.

title: Growth and Production of Eucalypto in Region the Médio Paraíba do Sul, RJ

description: ABSTRACT This study aimed to evaluate the production of Eucalyptus genetic materials, implanted in the town of Paty do Alferes, Rio de Janeiro. Were used four eucalyptus species, the hybrid Eucalyptus urophylla x E. grandis, from seedlings and two clones (yellow and white) of Eucalyptus urophylla x E. grandis. The region soil is water depleted from May to September. After planting, we evaluated the survival at 2 months and the diameter to the height of 1.30 meter from the ground, and total plant height at 18 and 80 months. In the latter measurement, six medium trees of each genetic material were abated to determine the volume and biomass of the wood. Eucalyptus grandis, yellow clone and Eucalyptus urophylla x E. grandis showed the best results, with the nominees for the formation of settlements in the region Médio Paraíba do Sul, RJ. Eucalyptus pellita showed lowest growth and yield.

title: Bottled water: microbiological quality and consumer perception in Viçosa (MG)

description: The objective of this study was to characterize the microbiological and physical quality of mineral bottled water commercialized in Viçosa's city, Minas Gerais' State, and understand the perceptions related to its consumption. Samples of four brands of bottled water, in gallons of 20 liters, were analyzed for microbial (Escherichia coli, total coliforms, enterococci, Pseudomonas aeruginosa) and physical (color and turbidity) characterization. In addition, bottled water's consumers were interviewed to identity the perceptions concerning water quality and the reasons for choosing this water; these data were analyzed using content analysis strategy. The results showed that bottled water commercialized in Viçosa's city had, at some point, microorganisms counting higher than those recommended by Brazilian's regulation. The results concerning the qualitative study showed that the choice for bottled water consumption is less related to the sense of health protection than to a social practice, consolidated and legitimated in everyday.

title: USE OF TREATED SEWAGE AS WATER AND A NUTRITIONAL SOURCE FOR BEAN CROPS

description: ABSTRACT Considering the relevance of the reduction or replacement of fresh water supplies for irrigation, to mitigate the use of agricultural fertilizers and to improve sustainability, this study aimed to evaluate water and nutritional efficiency of treated sewage in cowpea plots. The experiment was conducted in the city of Tianguá-CE, on land belonging to the Water and Sewage Treatment Company of Ceará. It used a randomized block design for the arrangement of split plots. The plots contained two water sources (treated sewage and well water). The subplots contained four irrigation levels based on potential evapotranspiration (50%, 75%, 100%, and 125% of ETc) and the sub-subplots contained four nitrogen, phosphorous, and potassium (NPK) levels (0%, 33%, 66%, and 99% of the nutritional recommendations for cowpea cultivation). The yield variables, number of pods per plant, bean numbers per pod, and bean production, were improved with increased irrigation, regardless of the water source. Examining NPK levels in particular, yields differed depending on the water source. The use of treated domestic wastewater for bean irrigation can replace up to 100% of commercial fertilizers.
