title: The Back Stress Behavior Study Analyzed in Residual Stress of Welded Naval Plates in Different Lamination Directions and Different Thermal Contributions

description: The lamination process adds the anisotropy characteristic in the final product. This anisotropy influences the yield strength according to the direction in question, the difference between the value of the yield tension in one direction and the value of the yield tension in another direction referred to as the back stress. Naval plates were welded by the GMAW process in the longitudinal direction to the lamination and in the transverse direction, and with different thermal loads. The residual stresses were calculated by displacement coordinate points method (DCP) and the back stress was found by tensile tests in specimen subjected made with either the longitudinal lamination direction and transverse lamination direction. The material used was ASTM A131 naval steel grade AH-36. The welded plates with greater thermal load in the longitudinal direction presented smaller residual stress in this direction, in relation to the transverse lamination direction. In the welded plates with greater thermal load, in the transverse lamination direction, the displacements in different directions were close, showing that the back stress does not act reversing the displacement (flow). Finally, for the welded plates with lower thermal load, both welded in the longitudinal and transverse direction, the displacements were small. In addition, the back stress did not act reversing such displacements.

title: Antifungal activities of the essential oil and its fractions rich in sesquiterpenes from leaves of Casearia sylvestris Sw.

description: ABSTRACT Casearia genus (Salicaceae) is found in sub-tropical and tropical regions of the world and comprises about 160-200 species. It is a medicinal plant used in South America, also known as “guaçatonga”, “erva-de-tiú”, “cafezinho-do-mato”. In Brazil, there are about 48 species and 12 are registered in the State of Rio de Janeiro, including Casearia sylvestris Sw. There are many studies related to the chemical profile and cytotoxic activities of extracts from these plants, although few studies about the antifungal potential of the essential oil have been reported. In this work, we have studied the antifungal properties of the essential oil of C. sylvestris leaves, as well as of their fractions, against four yeasts (Saccharomyces cerevisae, Candida albicans, C. glabrata and C. krusei) for the first time. The chemical analysis of the essential oil revealed a very diversified (n = 21 compounds) volatile fraction composed mainly of non-oxygenated sesquiterpenes (72.1%). These sesquiterpenes included α-humulene (17.8%) and α-copaene (8.5%) and the oxygenated sesquiterpene spathulenol (11.8%) were also identified. Monoterpenes were not identified. The fractions are mainly composed of oxygenated sesquiterpenes, and the most active fraction is rich in the sesquiterpene 14-hydroxy -9-epi-β-caryophyllene. This fraction was the most effective in inhibiting the growth of three yeast strains.

title: Medical Professionalism: the Effects of Sociodemographic Diversity and Curricular Organization on the Attitudinal Performance of Medical Students

description: ABSTRACT Introduction: Socioeconomic and demographic diversity in the educational environment and the development of professional attitudes enhance the quality of health care delivery. Despite the importance of diversity for equity and accessibility to health care, its repercussions for students’ attitudinal learning have not been adequately evaluated. Purpose: Evaluate the influence of academic sociodemographic diversity and curricular organization in the development of professional attitudes in different phases of the undergraduate medical curriculum. Method: In 2012, the attitudinal performance of 310 socioeconomically diverse medical students was evaluated by the administration of a five-point professional attitudes scale. The participants were at different points in their education at a Brazilian public school of medicine in Brasília, Federal District. The scale comprised 6 factors: communication, ethics, professional excellence, self-assessment, beliefs, social determinants; and a general factor called medical professionalism and was validated for the purpose of this research. The reliability coefficients (aCronbach) ranged from 0.65 to 0.87, according to different scale dimensions. Student diversity was analyzed according to differences in gender, age, religious affiliation, system of student selection and socioeconomic background. Results: The authors observed a decline in the mean attitude scores during the clinical phase compared to the preclinical phase of the curriculum. Female students displayed more positive attitudes than male students, and the students who declared a religious affiliation recorded higher attitude scores compared to those who declared themselves atheist, agnostic or non-religious. There was no correlation between family income or the system of student selection and the students’ attitude scores. The students who had attended public schools expressed a greater interest in working in the public health system compared to the other students. Age and marital status had no relevant effect on attitude scores. Conclusions: The attitude scores of medical students declined as the curriculum progressed. Female students had more positive attitudes than male students. Religious affiliation appeared to positively influence the observed attitude scores.

title: Porous Titanium Associated with CaP Coating: In Vivo and In Vitro Osteogenic Performance

description: This in vitro and in vivo study compared different topographies of Ti samples (dense, porosity of 30% and 40%) with or not CaP coating, prepared by powder metallurgy. Osteogenic cells from newborn rat calvaria were plated onto the samples and cell adhesion (24 hours), alkaline phosphatase activity (7 and 10 days) and mineralization nodules (14 days) were assessed. Sixteen rabbits were used for in vivo study. Each animal received three non-treated and three treated implants in the right or left tibia, respectively. Histometric evaluation of bone-implant contact (BIC) were assessed at 1, 2, 4 and 8 weeks. Metallographic analysis revealed porosities of 30% and 40%, with pore size ranging from 250 to 350 µm. Cell adhesion test and ALP revealed similar cell behavior, independently of topography and CaP coating (P &gt; 0.05%). However, CaP coating combined with porosity of 40% influenced positively the mineralized matrix formation (P &lt; 0.05%). CaP-coated implants showed higher BIC than non-CaP implants and BIC was different between the short (1 and 2 weeks) and long (4 and 8 weeks) healing periods (P &lt; 0.05%). The results suggest that CaP coating combined with 40% porosity implants allowed greater osteogenesis in vitro and increased BIC in vivo.

title: Artificial neural network for ecological-economic zoning as a tool for spatial planning

description: Abstract: The objective of this work was to analyze social and environmental information through an artificial neural network-self-organizing map (ANN-SOM), in order to provide subsidy to ecological-economic zoning (EEZ) as a tool to reduce the subjectivity of the process. The study area comprises 16 municipalities in the northeast of the state of Pará, Brazil, representative of the agricultural development in the state. Data processing involved three steps: preparation of the data in a geographic information system (GIS) environment; mathematical processing (ANN-SOM) of the data; and visualization and interpretation of the processing results, allowing the spatial planning of northeastern Pará. The results comprised 13 classes, regrouped according to behavioral similarity criteria into four categories, which represent the main areas of sustainability proposed for the state of Pará, according to existing EEZ. The proposed methodology allows individualizing areas in the region that EEZ had not defined, mainly due to the greater possibility of combining and integrating a large number of physical, social, and economic variables through the SOM.

title: Interdisciplinarity as a strategy for the prevention of systemic arterial hypertension in children: a systematic review

description: Abstract Researches that developed interdisciplinary actions in schools seeking to modify the arteial pressure levels or salt and/or sodium consumption by children were analyzed. Studies available on the PubMed, ScienceDirect and Lilacs databases, associating the keywords: intervention study, nutrition intervention, schoolchildren, school health, blood pressure, sodium and salt were included. The research included articles from the last 15 years, in Portuguese, English and Spanish, which had preschool or school children as participants. With respect to the change of the blood pressure levels, 7 studies with positive and significant results and 6 without variation were identified. In terms of modification of the ingestion of food with high salt and/or sodium content, 4 studies revealed positive and significant results, and only one was unsuccessful. The conclusions drawn are that the interventions that use nutritional education combined with physical activities prevail in the literature. However, these actions proved to be more effective when implemented over a long period of time.

title: The guide-interpretation in guy inclusion process of deafblind person

description: ABSTRACT Reflecting about the person with deaf-blindness and, above all, the treatment given to the deaf-blind in the social and educational context is an academic need, either in production of theoretical knowledge or in practical interventions. This problematic sets the paths taken by this article, in order to investigate the importance of professional practice of the guide-interpreter in helping people with deaf-blindness, from their communicative practices with the deaf-blind and characterizing which factors and aspects interfere with their professional activities as mediators for the socialization of the deaf-blind. This work bases its reflections on the socio-interactionist theoretical contributions, understanding that the relationship of the deaf-blind subject with the environment is an essential factor for the development of individuals. The bibliographical research enables analysis of the lack of information and expertise on disability as a factor in the emergence of structural, programmatic, attitudinal and architectural barriers, which affect both the quality of treatment to the deaf-blind, as well as the social reality of these individuals, thus providing a reality of exclusion and segregation.

title: The museological discourse and its typologies in a natural history museum

description: Abstract: Due to museums popularity and their social, cultural, and scientific roles, there has been a growing interest in investigating how teaching occurs at museums and their contributions to the public awareness of science. Museums present an innate type of discourse named museological, consisting of various elements found on explanations, which visitors can interact with. This study analyzes the museological discourse of a paleontological exhibition, concluding that it is essentially contemplative, with a predominance of authoritarian discourse on the exhibited texts, as seen in the pedagogical discourse. Reflecting on museum exhibitions and whom they are aimed at, with adjustments being made according to the audiences, what is important is the manner in which critical learning benefits and the importance of interactive objects and reflexive texts as facilitators of the process of the construction of meanings by the visitors themselves.
