Indústria frigorífica halal no Brasil, mão-de-obra islamita e estado de exceção

In the last decade, Brazilian meat export rates for Muslim religious countries have increased, and also has the immigration of Africans workers able to perform the slaughter following the precepts of Islam - religion that has expanded in the world, and thus, has the halal food segment. Halal, the Islamic ideology, means lawful, authorized by God: are those products that Allah in the Holy Qur'an releases for human consumption. To get halal certification some measures during slaughter/processing food should be taken. In the case of the slaughterhouses the animal must be slaughtered by a Muslim. Consequently, the demand for this skilled labor makes many African-Muslims get jobs in factories owned by BRF Foods, JBS and Marfrig; refugees and with their citizenship rights committed, these individuals live in a socio-political state of exception and overexploitation. In this study we intend to discuss the object of study Islamist workforce in Brazilian halal meat industry using the theoretical reflections of Giorgio Agamben (Homo Sacer in 2002, and State of Exception, 2004) and David Harvey (The Condition of Postmodernity, 2008, and The New Imperialism, 2004) to address the situation of immigrants in the meat business in Brazil, specially those on the halal certification segment, whose working and living conditions were described from academic studies and primary sources (articles in newspapers / magazines, websites, immigration official data). In addition we use the works of Rogério Heasbaert (O mito da desterritorialização, 2007) and Robert Kurz (Os paradoxos dos direitos humanos: inclusão e exclusão na modernidade, 2003) to discuss human mobility in this new century

Estudo da resistência à corrosão de ligas Ni-Cr-Mo-Ta E Ni-Cr-Mo-W em solução NaF 0,08 mol/L, pH 4,7 para aplicações odontológicas

A large number of metal alloys are used in Dentistry for the manufacture of fixed and removable dentures. In the oral cavity, these structures are exposed to a chemically aggressive medium, like saliva and mechanical efforts, like mastication. In addition, acidic solutions containing fluoride ions are also frequently used in dental treatments to prevent dental plates and decays development. In this context, it was considered important to investigate the influence that a fourth element could exert when added to the ternary alloy Ni-Cr-Mo, largely used in Brazil. Therefore, electrochemical tests were done to evaluate the resistance to corrosion of quaternary alloy 65Ni-25Cr-5Mo-5Ta and 65Ni-25Cr-5Mo-5W in NaF solution 0,08mol / L, pH = 4.7. For greater understanding the microstructure and morphology of alloys were studied, through metallographic analysis, using optics microscopy and electron microscopy scanning. For the electrochemical tests were applied techniques traditionally used in corrosion researches, such as: potential measures in open circuit (OCP) and cyclic polarization (CP). It was found that both quaternary alloys showed very similar results. Comparing these quaternary alloys with the ternary 65Ni-25Cr-10Mo, it was found that the quaternary alloys exhibit greater resistance to corrosion, in other words, less passivation current density than the ternary alloy, showing that it is advantageous to add a fourth element in the alloy

Análise da confiabilidade e reprodutibilidade da goniometria em relação à fotogrametria na mão

OBJETIVO: Avaliar a confiabilidade intra e interexaminadores e a reprodutibilidade da goniometria em relação à fotogrametria na mão, comparando os ângulos da abdução de polegar, flexão da AIFP do II dedo e flexão da AMCF do V dedo. MÉTODOS: PARTIciparam deste estudo 30voluntários foram divididos em 3 grupos, um grupo de 10 estudantes de Fisioterapia, outro por 10 fisioterapeutas e o terceiro com 10 terapeutas da mão. Cada avaliador realizou as medidas no mesmo molde de mão, utilizando o goniômetro e em seguidadois softwares de fotogrametria, o CorelDraw® e o ALCimagem®. RESULTADOS: Os resultados revelaram que os grupos e os métodos propostos apresentam confiabilidade interexaminadores no geral classificada como excelente (ICC 0,998 I.C. 95% 0,995 - 0,999). Na avaliação intraexaminadores, foi encontrado excelente nível de confiabilidade entre os três grupos. Na comparação entre os grupos para cada ângulo e cada método, observou-se que não houve diferença significativa entre os grupos para a maioria das medidas. CONCLUSÃO: A goniometria e a fotogrametria são métodos confiáveis e reprodutíveis para avaliação de medidas na mão. Porém, pela escassez de referências semelhantes, necessita-se de estudos aprofundados para definição de parâmetros de normalidade entre os métodos nas articulações da mão.

The paper makes a comparative e interpretative analysis through the reading of those products.

Synthesis and characterization of metal-chalcogenide MQ 2-Nanoparticles (M = Mo, W, Zr; Q = S, O)

Here, we present the adaptation and optimization of (i) the solvothermal and (ii) the metal-organic chemical vapor deposition (MOCVD) approach as simple methods for the high-yield synthesis of MQ2 (M=Mo, W, Zr; Q = O, S) nanoparticles. Extensive characterization was carried out using X-ray diffraction (XRD), scanning and transmission electron micros¬copy (SEM/TEM) combined with energy dispersive X-ray analysis (EDXA), Raman spectroscopy, thermal analyses (DTA/TG), small angle X-ray scattering (SAXS) and BET measurements. After a general introduction to the state of the art, a simple route to nanostructured MoS2 based on the decomposition of the cluster-based precursor (NH4)2Mo3S13∙xH2O under solvothermal conditions (toluene, 653 K) is presented. Solvothermal decomposition results in nanostructured material that is distinct from the material obtained by decomposition of the same precursor in sealed quartz tubes at the same temperature. When carried out in the presence of the surfactant cetyltrimethyl¬ammonium bromide (CTAB), the decomposition product exhibits highly disordered MoS2 lamellae with high surface areas. The synthesis of WS2 onion-like nanoparticles by means of a single-step MOCVD process is discussed. Furthermore, the results of the successful transfer of the two-step MO¬CVD based synthesis of MoQ2 nanoparticles (Q = S, Se), comprising the formation of amorphous precursor particles and followed by the formation of fullerene-like particles in a subsequent annealing step to the W-S system, are presented. Based on a study of the temperature dependence of the reactions a set of conditions for the formation of onion-like structures in a one-step reaction could be derived. The MOCVD approach allows a selective synthesis of open and filled fullerene-like chalcogenide nanoparticles. An in situ heating stage transmission electron microscopy (TEM) study was employed to comparatively investigate the growth mechanism of MoS2 and WS2 nanoparticles obtained from MOCVD upon annealing. Round, mainly amorphous particles in the pristine sample trans¬form to hollow onion-like particles upon annealing. A significant difference between both compounds could be demonstrated in their crystallization conduct. Finally, the results of the in situ hea¬ting experiments are compared to those obtained from an ex situ annealing process under Ar. Eventually, a low temperature synthesis of monodisperse ZrO2 nanoparticles with diameters of ~ 8 nm is introduced. Whereas the solvent could be omitted, the synthesis in an autoclave is crucial for gaining nano-sized (n) ZrO2 by thermal decomposition of Zr(C2O4)2. The n-ZrO2 particles exhibits high specific surface areas (up to 385 m2/g) which make them promising candidates as catalysts and catalyst supports. Co-existence of m- and t-ZrO2 nano-particles of 6-9 nm in diameter, i.e. above the critical particle size of 6 nm, demonstrates that the particle size is not the only factor for stabilization of the t-ZrO2 modification at room temperature. In conclusion, synthesis within an autoclave (with and without solvent) and the MOCVD process could be successfully adapted to the synthesis of MoS2, WS2 and ZrO2 nanoparticles. A comparative in situ heating stage TEM study elucidated the growth mechanism of MoS2 and WS2 fullerene-like particles. As the general processes are similar, a transfer of this synthesis approach to other layered transition metal chalcogenide systems is to be expected. Application of the obtained nanomaterials as lubricants (MoS2, WS2) or as dental filling materials (ZrO2) is currently under investigation.
