title: Suicide in Portugal: image of the country

description: ABSTRACT Objective To identify patterns of suicide trends registered in Portugal, taking into account a set of socio-economic and demographic variables between the years 2007 and 2014 in order to obtain an overview of this scourge in Portugal. Methods Using data from the National Institute of Statistics (INE) and the Death Certificate Information System (SICO), suicide was analyzed according to the category of ICD10 (International Classification of Diseases), the incidence by gender, age group and region. Results The most affected to suicide are men (54,8%), over 75 years old (30.9%) and occurs in the more rural areas of the interior of the country that are more deprived of materials. The highest suicide mortality is found in the Alentejo region (12,8%). Conclusion Mortality due to suicide continues to grow in Portugal and varies according to gender, age is highest in the Central and South regions. A strategy of follow-up and prevention in the field of social action and health care is required, with important regional variations and greater vigilance on the illegal trade in firearms and pesticides.

title: Cross-cultural adaptation of Rotter's General Locus of Control instrument

description: Abstract Objective To perform a cross-cultural adaptation of the General Locus of Control (GLoC) questionnaire, which measures where people place causation of events in their lives, i.e., if they interpret events as being the result of their own actions or external factors. Methods After translation and back-translation, a multidisciplinary committee judged and elaborated different versions of the GLoC questionnaire, with a focus on conceptual equivalence, content, comprehensibility and adjustment to the Brazilian socioeconomic context. The final version was tested on 71 healthy subjects, of whom 36 were reinterviewed and answered the GLoC questionnaire twice, after a mean of 73.06±74.15 days (range = 29-359). Results The participants' mean age was 30.82±12.83 years (range = 18-69), 62% were women, and mean years of schooling were 12.54±4.21. Test-retest reliability (Pearson's) was r = 0.828. Internal consistency resulted in a Cronbach's alpha of 0.906. The mean GLoC score obtained was 8.77±3.11 (n = 71). Conclusion The Portuguese version of the GLoC questionnaire is a faithful adaptation of Rotter's original questionnaire.

title: Evaluation of Co-Ni/SiC Nanocomposite Coating Obtained by Electrodeposition on the Corrosion Resistance of API 5L X80 Steel

description: Co-Ni/SiC nanocomposite coatings were obtained by codeposition of SiC nanoparticles in a bath with nickel and cobalt, using API 5L X80 as the substrate. The influence of cathodic current density on deposit properties was investigated. Measurements of electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) were performed in 3.5 wt% NaCl solution to investigate a corrosion performance. The morphology and chemical analysis of the surfaces were analyzed by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) and related with micro-hardness and X-ray diffraction (XRD). The results indicate which composite coatings have acicular morphology, with higher micro-hardness values than those found for the carbon steel substrate. The Co-Ni/SiC coating increased the corrosion potential and the resistance to polarization, which resulted in lower corrosion rates than those obtained without uncoated steel.

title: FLEXIBLE WORK ARRANGEMENTS AND THE MEANING OF WORK FOR TEACHERS OF HIGHER EDUCATION IN PUBLIC AND PRIVATE INSTITUTIONS

description: Abstract This article aims to understand the meaning of the work for the higher education teacher in public and private institutions in their various regimes of work flexibility based on the identification of instrumental and subjective rationality elements. The collection of data had multiple sources, such as the documentary analysis of institutions and teachers’ work contracts, direct observation and personal interviews. As a result it was noticed that: there is a preponderance of the substantive meaning of the work on the instrumental sense; the flexibilization alters the perception of individual performance and infers on its substantive sense, and life is arranged from the organization of work flexibilized.

title: CONTRADICTIONS BETWEEN THE GREAT DEMAND AND THE SMALL OFFER OF THE HEMOTHERAPY TECHNICIAN COURSE IN BRAZIL

description: Abstract The blood sector regulations in Brazil started to require specific levels of schooling geared to technical and practical knowledge of hemotherapy and immunohematology. This article aimed to identify, understand and analyze the images, ideas and perceptions about hematology y technical course taught in a school of public health, in Brazil. Methodologically, this was action research carried out between March 2012 and December 2013, with teachers, students and technical references. We found that the course was considered relevant, with good content, despite its centralization in the city in the southeast of the country. We conclude that schooling in hematology is done urgently, however, inserting techniques and process of labor relations in the field of Hematology is marked by weakness and absence of the guidelines.

title: CONCEPTS OF HEALTH ON THE AGENDA OF THE NATIONAL CONFEDERATION OF EDUCATION WORKERS

description: Abstract This article aims to identify and analyze the concepts of health present in teachers’ demands at the National Confederation of Education Workers, in Brazil. It is the result of a documental research carried out on the resolutions of congresses held by the labor union in the period from 1999 to 2014. Using content analysis of documents, references to health were classified in demands either of economic-corporative or ethical-political nature. The results of the documental investigation indicate that, besides a strict concept of health marked by corporative demands, there is also a broad concept of health. The demand for health under the perspective of a social right guaranteed through public policies may be a fertile pathway for the defense of health in its ontological sense, rather than as an economic factor understood as merchandise and sufficient to reproduce the workforce.

title: Ballistic Efficiency of Multilayered Armor Systems with Sisal Fiber Polyester Composites

description: The urban violence and the different types of global armed conflicts demand efficient protective systems against high energy ammunition. Multilayered Armor Systems (MAS) provide efficient protection by making use of lighter and more efficient materials. A typical MAS may be composed of three layers: a front ceramic followed by a composite, backed by a ductile metal. Polymer composites reinforced with natural fibers have proven to be effective second layers, being also lighter, low-cost and environmentally friendly as compared to conventional composites like KevlarTM. The present work evaluates MAS using as second layer polyester composites reinforced with 10, 20, and 30 vol. % of sisal fibers. Ballistic tests were performed using class III 7.62x51 mm ammunition, based on the NIJ 0101.06 backface signature methodology. Both the 30 vol.% sisal fiber composite and the conventional aramid laminates were equally efficient in terms of MAS second layer. The explanation might be the similar capacity of the different composites to retain the fragments generated by the interaction of the projectile with the front ceramic, independently of the percentage of sisal fibers.

title: Characterization of Niobia-alumina Deposited by the Sol-gel Process on Carbon Steel

description: The precursor sols of Al2O3 and mixed NbxOy/Al2O3 oxides were synthesized by the sol-gel process using acetylacetone to control the reaction kinetics of the organometallic oxides in the mixture. The layers of the precursor sols of Al2O3 and NbxOy/Al2O3 were deposited on AISI steel 1020 by manual immersion (dip coating). The lyophilized sols were characterized by X-ray diffraction, thermal analysis and scanning electron microscopy with EDXS before the recoating process. The influence of the ceramic coating of corrosive processes of AISI steel 1020 were investigated by electrochemical measurements. The only identified phase was poorly crystallized boehmite with homogeneous mixture of Al, Nb, O and C ions in mixed NbxOy/Al2O3 oxides. The ceramic layers deposited appeared to have physical and chemical homogeneity and the steel samples with these deposits had lower corrosion potential. However, the precursor sol Al2O3 showed better steel corrosion protection with lower current density, and more corrosive potential.

title: Lubricated Conditions Imposed on Coating Multi-layer on Wear Resistance Under Cr2O3 Effect

description: Lubricated pin-on-disk sliding wear tests were performed on applied to Al-0.1Mg-0.35Ni-Si Alloy by using the spray coating method has been investigated. Different loads were 5, 10, and 15 N at a sliding velocity, 1.32 m/s at room temperature and 60% relative humidity. The surfaces were analyzed by using X-ray diffraction the residual (XRD), energy dispersive (EDS), scanning of (SEM) and (AFM), respectively. The results have showed that the thickness of Cr2O3 coating was significantly related under the identical cold spray condition. These methods have contributed much of the understanding of quality and properties of surfaces. The (Cr2O3) coating has great potential as a wear-resistant. The hardness increased from 102 ± 5 HV to 116.4 ± 2.5 HV at coating thickness 45 µm and friction coefficient reduced from 0.29 to 0.24; and the wear rate was about 2.11X10-13 m3N-1m-1 while hardness was increased from 102 ± 5 HV to 108 ± 3.5 HV at coating thickness 15 µm. The friction reduced from 0.31 to 0.29 at same coating thickness alloys, and the wear rate was about 2.73X10-13 m3N-1m-1. The tribological properties of Cr2O3 coating have exhibited low friction and beneficial to improve the adhesion which was clear on worn surfaces of Cr2O3 coating. Crack, powder flocculation and powder formation are caused by the wear mode of the surface. Brittle fracture was found; while, adhesion and oxidation are the main mechanism of wear during the test.
