A governamentaliza??o do Estado contemporaneo: uma cartografia dos mecanismos estatais de controle
Benites, Luiz Felipe Rocha;
Sociologias , 2004, DOI: 10.1590/S1517-45222004000200010
Abstract: this essay examines the process of "governmentalization" of the state and its consequences for the its own community. based on genealogic works and contemporary studies, an attempt is made at mapping some ways in which mechanisms for control and regulation of populations are begin re-created and re-organized, renewing the normalizing ability of the state domain. the analysis points out the move of contemporary government into the territory of immaterial labor within public service when it articulates the use of new telematic technologies with the production of subjectivities which "desire" control.

Benites Luiz Felipe Rocha
Sociologias , 2004,
Abstract: Este ensaio analisa o processo de "governamentaliza o" do Estado e as implica es desse processo para a sua própria continuidade. Nutrindo-se de trabalhos genealógicos e estudos contemporaneos, procura-se cartografar alguns caminhos pelos quais os mecanismos de controle e regula o das popula es est o sendo recriados e reorganizados, renovando a capacidade normalizadora do campo estatal. A análise aponta que o exercício do "governamento" contemporaneo avan a no território do trabalho imaterial no servi o público ao articular o uso de novas tecnologias telemáticas com a produ o de subjetividades "desejantes" de controle.
Cultura e Reversibilidade: breve reflex o sobre a abordagem “inventiva” de Roy Wagner
Luiz Felipe Rocha Benites
Campos - Revista de Antropologia Social , 2007,
Abstract: Em meados da década de 1970, Roy Wagner, no seu livro The Invention of Culture, toma a antropologia comodisciplina que inventa a cultura a partir da cultura. Alicer ado na sua experiência de campo com os Daribi,da Nova Guiné, o autor apresenta a no o de cultura como atividade criativa, na qual somos todos agentesinventivos. Nesta perspectiva, antropólogo e “nativo” realizam opera es similares e, por conseguinte, o estudoda cultura consistiria na cultura do antropólogo. é ainda nesta obra que Wagner cunha o termo “antropologiareversa”, para p r em quest o a posi o privilegiada do etnógrafo no que diz respeito à elabora o de uma“análise antropológica”. Diante do exposto, este artigo busca refletir sobre algumas implica es da ado o detal perspectiva em antropologia, conectando-a a alguns debates contemporaneos da disciplina, principalmentesobre eixos como a dicotomia “nós/eles” e sobre o estatuto da etnografia.
Effect of Carbon Fillers in Ultrahigh Molecular Weight Polyethylene Matrix Prepared by Twin-Screw Extrusion  [PDF]
Luiz Felipe M. Rocha, Suellem B. Cordeiro, Leonardo C. Ferreira, Flávio James H. Ramos, Maria de Fátima Marques
Materials Sciences and Applications (MSA) , 2016, DOI: 10.4236/msa.2016.712066
Abstract: Oxidized (GO) and expanded (G-Exp) graphite were employed to prepare composites with ultrahigh molecular weight polyethylene (UHMWPE) matrix using masterbatches of polyethylene with different compositions. The materials and a blend of UHMWPE/HDPE were prepared by extrusion and their properties were evaluated. The effect of carbon fillers on the crystalline structure, thermo dynamic-mechanical (DMTA) and thermal properties (melting and crystallization temperatures) of the composites were discussed. The thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) measurements showed that the addition of masterbatch with GO and G-Exp significantly increased the crystallite size of composites, increasing the temperatures of melting, degradation, glass transition and the degree of crystallinity of polyethylene. DMTA analysis indicated the storage and loss moduli of composites in relation to neat UHMWPE, the blend and UHMWPE/composites. SEM micrographs showed a flatter, continuous and uniform surface meaning a compact lamellar structure. The present work resulted in interesting findings on the effects of GO on the crystalline structures, mechanical and thermal properties of UHMWPE, which can lead to generalizations useful for future work.

Arquivos de Neuro-Psiquiatria , 2002,
Abstract: As manifesta es neurológicas associadas à deficiência de vitamina B12 incluem polineuropatia, mielopatia, demência e neuropatia óptica. O diagnóstico laboratorial é feito através da dosagem sérica de cianocobalamina ou homocisteína e da excre o urinária de ácido metilmal nico. No estudo anatomopatológico observa-se na microscopia a destrui o da mielina e de ax nios vistos na substancia branca. A regi o mais comumente afetada é o cord o posterior cervical e/ou torácico. O acometimento da coluna lateral é raro, ocorrendo em casos graves e avan ados. O tratamento consiste na reposi o de vitamina B12 e a resposta depende da gravidade do quadro e do tempo transcorrido entre o inicio dos sintomas e inicio do tratamento. Relatamos o caso de um paciente que apresentou, como manifesta o de deficiência de vitamina B12, mielite transversa. O estudo morfológico da medula demonstrou comprometimento dos tractos cortico-espinhais lateral e anterior, da coluna dorsal e ainda do tracto espino-talamico.

Abstract: OBJETIVO: Avaliar o impacto da infec o pelo HBV (vírus da hepatite B) e pelo HCV (vírus da hepatite C) na sobrevida a longo prazo de pacientes transplantados renais e seus enxertos. MéTODOS: Cento e nove pacientes transplantados renais foram avaliados quanto à presen a de anticorpos contra o HCV e presen a do antígeno de superfície do HBV. Os pacientes foram divididos em quatro grupos, de acordo com os resultados das sorologias, e seguidos pelo período de 10 anos para avalia o das sobrevidas. As diferen as de idade, sexo, etiologia da insuficiência renal, tempo de diálise, e tempo pós-transplante renal foram avaliados nos grupos. RESULTADOS: Os grupos diferiram apenas nos parametros de tempo de diálise prévio ao transplante renal, sendo este significativamente maior nos pacientes anti-HCV positivos. Houve maior número de pacientes re-transplantados nos grupos anti-HCV e HbsAg positivos. N o houve diferen a significativa nas sobrevidas de pacientes infectados pelos vírus B ou C (grupo anti-HCV positivo sobrevida de 10 anos: 71,0%; risco relativo: 1,13; IC 95%: 0,86 - 1,47. Grupo HbsAg positivo sobrevida de 10 anos: 77,8%; risco relativo: 1,03; IC 95%: 0,7 - 1,5). O grupo com co-infec o pelos vírus B e C apresentou sobrevida de 10 anos significativamente menor que os demais (37,5%; risco relativo: 2,13; IC 95%: 0,86 - 5,28). Todos os grupos foram comparados à sobrevida de 10 anos com o grupo índice (sem infec o pelo HbsAg ou anti-HCV), que foi de 80,0%. As sobrevidas dos enxertos n o apresentaram diferen as com significancia estatística. CONCLUS O: No presente estudo evidenciou-se diferen a significativa na sobrevida de pacientes transplantados renais infectados concomitantemente pelos vírus das hepatites B e C.

Vasconcellos Luiz Felipe Rocha,Peixoto Maria Claudia,Oliveira Tatiana Nunes de,Penque Glória
Arquivos de Neuro-Psiquiatria , 2003,
Abstract: The frequency of myopathy in hypothyroidism ranges from 30 to 80%. The major symptoms related are weakness, muscular cramps and myalgia. The pseudohyperthrophic form is called Hoffman's syndrome. The electrophysiological study reveals myopathy, neuropathy or mixed pattern. Laboratorial investigation generally shows increased levels of muscle enzymes and low serum thyroid hormones, with thyrotrophic-stimulating hormone (TSH) elevated. The treatment consists in hormone replacement and the prognosis is good in most of the cases. We report an adult male who developed muscular cramps, myalgia, weakness, pseudohyperthrophy, associated with facial edema and alteration of his voice. The muscle enzymes were increased and T4 was undetectable with a raised level of TSH. The myopathy was the initial manifestation of hypothyroidism in this case.

Abstract: The milking is a fundamental step for getting quality milk products, and factors related to the hygiene of the animal teats and of the milking equipment can take to contamination of the milk, raising this product’s bacterian count. Experiments were carried to evaluate the efficiency of the predipping on teats bacterian contamination reduction and on bacterian count of milk from cows that have been submitted to different conditions of preparation for the milking, and the susceptibility to antimicrobials profile of milk bacteria. On the experiment that tested the efficiency of the predipping there was significant difference as to the number of teats with Staphylococcus sp and also positive Gram bacilli between treatments with no sanitation or with water sanitation and predipping. As to the milk bacterian count of the mammary quarters, there was significant difference between the treatments without sanitation and pre-dipping. As to the bacterian susceptibility to antimicrobials, it showed resistance to five, from the eight that were tested, in at least one sample, being them: amoxilicin+clavulanic acid, enrofloxacin, gentamicin, G penicillin and vancomycin. The results allowed to conclude that: the predipping represents and important tool to reduce contamination on teats, as well as on milk; the presence of coagulase-negative Staphylococcus sp resistant to certain antimicrobials, like vancomycin, wasn’t expected, being a relevant observation from the milk quality point of view. A ordenha constitui-se em etapa fundamental para a obten o de produtos lácteos com qualidade, sendo que, fatores relacionados à higiene dos tetos dos animais e dos equipamentos de ordenha podem levar à contamina o do leite elevando as contagens bacterianas deste produto. Tendo como objetivos avaliar a eficiência do pré-dipping na redu o da contamina o bacteriana da pele dos tetos e do leite de vacas submetidas a diferentes condi es de preparo para a ordenha e o perfil de suscetibilidade a antimicrobianos de bactérias presentes no leite, foram realizados experimentos em um rebanho leiteiro. Ao testar a eficiência do pré-dipping, observou-se diferen a significativa no número de tetos com Staphylococcus sp e bacilos Gram positivos entre os tratamentos sem higieniza o ou higieniza o com água e pré-dipping. Quanto à contagem bacteriana do leite, houve diferen a significativa entre os tratamentos sem higieniza o e pré-dipping. Quanto à suscetibilidade bacteriana a antimicrobianos, de oito testados, observou-se resistência a cinco, em pelo menos uma amostra, s o eles: amoxicilina+á
