title: An analysis of bodies in movement in the ether under the perspective of Fresnel's wave theory of light

description: Abstract The Fresnel's wave theory of light, far from being a mere theoretical speculation, enjoyed in the nineteenth century of recognition by the scientific community. This recognition was due to its ability to explain phenomena with very good agreement with the experimental results, at least up to first order approximations in β ( = V / c ). Many authors have already discussed the historical background in which this theory emerged and its implications for the physics by that time, as well as the experimental evidence supporting it, but the details of how these observations and / or experiments corroborate the Fresnel optics. In this work, we show how the Fresnel wave theory is able to explain experimental observations known at his time, namely: the aberration of light, the prism and the moving mirror in the ether, Fizeau's experiment.

title: TEACHERS’ SOCIAL REPRESENTATIONS CONCERNING THE PROJECT FOR CAREER IN PROFESSIONAL TEACHING IN CHILE. STRUCTURAL DISCOURSE ANALYSIS

description: ABSTRACT The socio-political processes in education affect the teaching profession. The objective of the article is to analyze the social representations of teachers and other relevant actors in relation to the Project of Professional Teacher Development Law. The methodological strategy was the structural analysis of the discourse published between March and June 2015. The findings reveal social representations that demand greater participation in the construction of the project; challenge the accountability-based approach to teacher assessment; argue that the project will intensify the dismissal, deprofessionalization and impoverishment of working conditions and believe that it is necessary to regulate the initial and continuous training of teachers. In sum, teachers reject the initiative as non-representative, based on mistrust and validating a punitive evaluation system that makes them invisible as a relevant actor in the design of the aforementioned bill.

title: Experimental realization of the simulation of Deutsch's algorithm using Mach-Zehnder interferometer

description: Abstract We present in this work the experimental realization of the simulation of Deutsch's algorithm using a Mach-Zehnder interferometer setup, as previously proposed by Cabral and coauthors [20]. Our setup allows the simultaneous entrance of two qbits, as in Deutsch's circuit. The results showed a limitation of this interpretation. The Mach-Zehnder interferometer simulates output results of Deutsch's circuit due to the control of phase difference between the arms of the interferometer, independently of the second qbit. Although our experiment was realized using a intense beam, we showed the concordance of our results with the expected results for unique photons. Our results agree with many works that use intense beams to explore the fundamentals of quantum information and quantum computation. It is an interesting scenario to discuss and teach fundamental aspects of quantum mechanics.

title: SCHOOL INCLUSION AND INDIVIDUALIZED EDUCATIONAL PLANNING: A COMPARATIVE STUDY ON PLANNING PRACTICES IN DIFFERENT COUNTRIES

description: ABSTRACT An historical overview is outlined about the individualized educational plan (IEP) concept and the consequent changes in their practice due to school segregation and inclusion. Then, analyzing the legislation on IEP and the models of execution of this type of planning in other countries, namely: France, Italy, the United States and Brazil. The model of IEP in France is broader, encompassing the whole life cycle. In the United States and Italy, the model focuses on the exclusive planning of school life, although all emphasize the importance of measures to control the transition process from school to work or/and community. Brazil does not have provisions in legislation to ensure that such students have an IEP based on their peculiarities, resulting in a planning more strongly focused on the existing services rather than on student needs. Thus, although the announced era is of school inclusion, planning practices have not changed.

title: Prevalence and Factors Associated with Depression and Anxiety among University Students in the Field of Health in a Large Urban Center in the Northeast of Brazil

description: ABSTRACT INTRODUCTION Despite the high levels of depression and anxiety, health professionals still have difficulties when dealing with these illnesses, particularly when they involve university students and professionals in the field of health. OBJECTIVE To estimate the prevalence and the factors associated with depression and anxiety among university students in the field of health. METHODS A transversal, analytical study involving students in the first year of a degree in health (biomedicine, nursing, physiotherapy, medicine and odontology) at a University Center in Ceará. Three questionnaires were applied. The first involved sociodemographic aspects, the second was the Beck Depression Inventory – BDI, and the third was the Beck Anxiety Inventory – BAI (both adapted and standardized for Brazil). The data were digitalized using the software Epi-info version 3.5.1, and analyzed in Stata 11.2. Bivariate analysis was performed for the associations between the variables by means of the Prevalence Ratio (PR), as well as their respective intervals of confidence, with a level of significance of p &lt; 0.05. The project was approved by the REC, with CAAE number 1.132.140, of June 30, 2015. RESULTS 476 students answered the questionnaires. The female sex was prevalent (71.6%), with the majority of students under 20 years of age (69.3%), and single (92.0%). The prevalence rates for depression and anxiety were 28.6% and 36.1%, respectively. Students who were less satisfied with the course had a four times higher likelihood of having depression (p &lt; 0.001). Risk factors were highlighted, such as unsatisfactory family relationships (p &lt; 0.001), lack of sleep (p=0.006), and unsatisfactory relationships with friends (p &lt; 0.001). The prevalence of anxiety was more closely associated with the female sex (p &lt; 0.001), and with unsatisfactory relationships with family members (p &lt; 0.001), friends (p = 0.005) and colleagues (p &lt; 0.001). Having insomnia (p &lt; 0.001), not doing much physical activity (p = 0.040), and a higher concern about the future (p = 0.002) also presented significant association with anxiety status. CONCLUSION The significant prevalence of anxiety and depression among students in the field of health were much higher than among the general population, with physiotherapy students having the highest result.

title: Sensitivity analysis of the AquaCrop parameters for rainfed corn in the South of Brazil

description: Abstract: The objective of this work was to perform a sensitivity analysis of the main input parameters required for the AquaCrop water balance model, using biomass and grain yield data of a rainfed-simulated corn crop, obtained along the climate data series of 1987-2016 in the South of Brazil. The levels of soil-water stress and the depths of maximum effective rooting were the input parameters that most affected the biomass and grain yields simulated by the model, followed by the crop coefficient, water-use efficiency, soil water storage capacity, and contribution of groundwater to water availability in the root zone. The parameters crop cycle duration, plant density, pattern of soil-water extraction, and field surface practices showed little or no impact on the final results. AquaCrop is a robust water balance model, with small or moderate general sensitivity to variations of the main input parameter values, which makes it applicable to situations with field data limitations.

title: Quasi-static processes, reversibility and the limits of thermodynamics

description: Abstract This work presents, by means of the classical formalism of thermodynamics courses, a study of the relation between the quasi-static nature of a thermodynamic process and its reversibility. In addition, from the results obtained by assuming the reversibility of a thermodynamic process composed by a fundamentally irreversible sub-process, we explore the limits of application of the Laws of Thermodynamics and the nuances contained in its general formulations. We consider that this paper has two well defined purposes: didactic and fundamental. The didactic point of view is evident when we use the calculus techniques for the extraction of the thermodynamic quantities in the infinitesimal processes and by putting the reader in contact with the techniques of proof by contradiction (if a hypothesis leads to a contradiction, then it can not be assumed). Both techniques can be seen as essential in the approach of a huge number of problems in physics. From the fundamental point of view, we have been able to evidence the intimate relationship between the First and Second Laws of Thermodynamics when we deal with the determination of the conditions of reversibility and existence of thermodynamic processes.

title: Black entrepreneurship and ethnic beauty salons: possibilities forresistance in the social (re)construction of black identity

description: ABSTRACT This paper addresses the case of five lack entrepreneurs who own businesses a public that for years has denied a esthetic and phenotypic traits. These spaces, branded as ‘ethnic salons’, aim to take care of the curly and / or Afrohair of Black men and women.In the face of this context, we ask: how canBlack entrepreneurs and enterprisesconfront colonialmentality in social relations, by creating businesses aimed at giving value to, and appreciatingthe identity of Black men and women? The field research was conducted via observations and interviews,collecting narratives from both. The narratives went through a process of synthesis and analysisprocesses that allowed us to flag the motivesbehind these enterprises, as well as the racial/ethnic acceptance present in these spaces. Thus, the main contribution of this paper is to discuss ‘hairtype’ as a constitutive element of Black racial identity, and the opportunity for more autonomywhen entering the labor market.

title: Right Ventricular Functional Improvement after Pulmonary Rehabilitation Program in Patients with COPD Determined by Speckle Tracking Echocardiography

description: Abstract Background: Although right ventricular (RV) dysfunction in pulmonary diseases has been associated with increased morbidity, tools for RV dysfunction identification are not well defined. Objective: The aim of this study was to evaluate the magnitude of RV dysfunction by means of speckle tracking echocardiography (STE) in patients with chronic obstructive pulmonary disease (COPD) and to investigate whether STE could be used as an index of RV improvement after a pulmonary rehabilitation (PR) program. Methods: Forty-six patients with COPD undergoing PR program and 32 age-sex matched healthy subjects were enrolled. RV function was evaluated at admission and after PR program by conventional two-dimensional echocardiography (2DE) and STE. In addition, exercise tolerance of subjects was evaluated using the six-minute walk test (6MWT). Results: COPD patients had worse RV function according to STE and 2DE as well. STE was more sensitive than conventional 2DE in determining RV improvement after PR program - RV global longitudinal strain (LS): 20.4 ± 2.4% vs. 21.9 ± 2.9% p &lt; 0.001 and RV free wall LS: 18.1 ± 3.4% vs. 22.9 ± 3.7%, p &lt; 0.001). RV free wall LS was directly related to distance walked at baseline 6MWT (r = 0.58, p &lt; 0.001) and to the change in the 6MWT distance (6MWTD ∆) (r = 0.41, p = 0.04). Conclusions: We conclude that STE might be as effective as 2DE for evaluation of global and regional RV functions. STE may become an important tool for assessment and follow-up of COPD patients undergoing PR program to determine the relationship between RV function and exercise tolerance.
