1. Nuclear Medicine Methods for Assessment of Chronic Chagas Heart Disease
Abstract Several different imaging methods can be used to evaluate patients with Chagas heart disease (CHD) for diagnostic and prognostic purposes, including plain chest radiography; echocardiography; myocardial perfusion scintigraphy, for detection of ischemia and fibrosis; radionuclide gated-angiography, for evaluation of biventricular function; 123I-MIBG

2. Discutindo o gerenciamento para a mudança: o framework 5M
Resumo Este artigo tem como objetivo discutir e apresentar a sustentação teórica do framework 5M, desenvolvido com o intuito de conduzir gestores de uma visão acrítica e racional do gerenciamento da mudança para uma leitura mais crítica e pragmática, focada no gerenciamento para a mudança. Adotou-se a abordagem da mudança como drama, combinando o q

3. ARTIGO - PAULO FREIRE: OUTRO PARADIGMA PEDAGÓGICO?
RESUMO: O texto lembra os 50 anos da publicação da Pedagogia do Oprimido de Paulo Freire. Que interrogações chegam hoje dos oprimidos para o pensamento pedagógico? A Pedagogia do Oprimido revela que estes são novos tempos de opressão. As opressões aumentam, com requintes políticos. Os oprimidos repõem outro paradigma de formação humana, outro par

4. Knowledge and attitudes of official inspectors at slaughterhouses in southern Brazil regarding animal welfare
ABSTRACT We assessed the views, knowledge, and attitudes of livestock inspectors working in federally inspected slaughterhouses in southern Brazil, the major pig and poultry processors in the country, regarding farm animal behavior and welfare, and factors that may influence animal welfare improvements at abattoirs. An online questionnaire with closed and op

5. MINIMIZING THE PREPARATION TIME OF A TUBES MACHINE: EXACT SOLUTION AND HEURISTICS
ABSTRACT In this paper we optimize the preparation time of a tubes machine. Tubes are hard tubes made by gluing strips of paper that are packed in paper reels, and some of them may be reused between the production of one and another tube. We present a mathematical model for the minimization of changing reels and movements and also implementations for the heu

6. Local piezo-response for lead-free Ba0.9Ca0.1Ti0.9Zr0.1O3 electro-ceramic by switching spectroscopy
The purpose of this work is to determine the effective piezoelectric coefficient (d33) and the macro ferroelectric hysteresis behavior for the Ba0.9Ca0.1Ti0.9Zr0.1O3 (BCZT). The sample was prepared by the modified Pechini method and it was sintered at 1250 ºC for 5 h. The refinements of X-ray diffraction (XRD) patterns obtained by the Rietveld method sugges

7. Synthesis and Characterization of LiCoO2 from Different Precursors by Sol-Gel Method
Lithium cobalt oxide, LiCoO2, widely used as cathode in lithium ion batteries was synthesized and their structural and electronic properties investigated. The crystalline powders were prepared by the sol-gel method with four complexing agents: citric acid, glycine, starch and gelatin. These syntheses were compared with the blank test (without complexing agen

8. THEORETICAL RESEARCH ON THE MULTI-CHANNEL REACTION MECHANISM AND KINETICS OF HNCS WITH OH-
We presented a theoretical study on the detailed reaction mechanism and kinetics of the HNCS molecule with the OH-. The barrierless minimum energy path and the most favorable entrance channel have been determined by study the thermodynamic and kinetic characters of the channel with low energy barrier. The B3LYP/6-311++G** method was employed for all the geom

9. Refining the ideas of "ethnic" skin
Abstract: Skin disease occur worldwide, affecting people of all nationalities and all skin types. These diseases may have a genetic component and may manifest differently in specific population groups; however, there has been little study on this aspect. If population-based differences exist, it is reasonable to assume that understanding these differences ma

10. Las Funciones Semióticas como Instrumento de Diagnóstico y Abordaje de Errores
Abstract Semiotic functions are theoretical and methodological tools used by the Ontosemiotic Approach of Cognition and Mathematics Instruction (OSA) to study the construction of meanings of mathematical objects. In this paper, through some examples, the use of such functions is described for dealing different problems in university students learning. From t

11. Psychometric properties of Multidimensional Health Locus of Control - A and General Self-Efficacy Scale in civil servants: ELSA-Brasil Musculoskeletal Study (ELSA-Brasil MSK)
Abstract Background Health-related control and self-efficacy beliefs can be assessed in the general population using Multidimensional Health Locus of Control-A subscales (MHLC-A) and the General Self-Efficacy Scale (GSES), respectively. Objective To test construct validity, internal consistency, reliability (test-retest) and ceiling and floor effects of Po

12. Formation of Aluminum Titanate with Small Additions of MgO and SiO2
The formation of aluminum titanate was investigated by isothermal treatments of samples obtained from equimolar mixtures of alumina and titania, containing small amounts of silica and magnesia. Results of differential thermal analysis and Rietveld refinements of data collected by X-ray powder diffraction (XRPD) showed that additions of silica in amounts used
