Consciência Política e Corrupção em Moçambique: entre a subalternidade e a transformação

Este artigo discute a importância da Visita Domiciliar, os efeitos O presente artigo aborda a corrupção em Moçambique a partir do olhar de pessoas que nem estudam e nem têm papel de destaque na sociedade moçambicana. Para essa análise utilizou-se do referencial psicopolítico da consciência política e observou-se como a questão da etnicidade e da sobrevivência ganham força a hora de entender a vida cotidiana em uma sociedade pluriétnica e marcada pelos traumas de uma guerra civil. Subalternidade e transformação se revelam como elementos espaço-temporais da cotidianidade moçambicana

Optimal locations of groundwater extractions in coastal aquifers

A regional water supply management model for coastal aquifers was developed. One of its outcomes is the definition of the optimized locations for groundwater withdrawal. Such a tool permits the analysis of alternative plans for groundwater extraction and the sustainable use of water resources in a coastal aquifer subject to saltwater intrusion. The principal components are the evolutionary optimization and the analytical/numerical simulation models. The optimization technique looks for the best well locations taking into consideration the economic results and the satisfaction of the societal water demand. However these two concerns are conditioned by trying to control the saltwater intrusion, i.e., preserving the environmental equilibrium. The simulation model uses the governing mathematical equations for groundwater movement to find the interface between freshwater and saltwater. Because of the non-linearity in the system and the possibility of a jumping interface, a security distance was defined. This is a controlling variable which can be set by the decision makers. The model was applied to a typical case with interesting results. For example, diagrams showing the relationship between the location of the wells and the security distance(s) are of importance to the managers. It was also crucial to have an understanding of the tradeoffs between groundwater withdrawals, positions of the wells from the coast line, and the security distance. The model was also applied to a real case in order to relate the extractions, distances and artificial recharge (not presented in this paper).Civil Engineering Research Centre of the University of Minho.Science and Technology Foundation -POCTI/ECM/2512/9

Socio-professional profile of the foreign teacher in Brazilian public university

Este trabajo, fruto de una tesis de doctorado en educación, tuvo como objetivo comprender la figura del profesor extranjero, su perfil, dificultades, retos y contribución a la permanencia en la reconstrucción de las prácticas didáctico-pedagógicas y su actuación como profesional docente en las universidades públicas brasileñas. El estudio se justifica debido a su número creciente, particularmente durante en los últimos diez años y que, por lo tanto, no ha sido objeto de investigación sistemática. Nuestro universo de investigación ha sido la UNB, Universidad pública federal de Brasilia, que concentra el mayor número de estos profesores. Utilizamos los datos del INEP (microdatos del censo de la educación superior, 2011) como base para localizar a estos docentes. Se aplicaron cuestionarios a más de 37,3% de las nacionalidades presentes (19 de 51 nacionalidades) que corresponde al 7,6% de una población estimada de 250 docentes, como documentos de consulta (sitios web de la escuela, sitio web personal, servicios de fotocopia). El análisis cualitativo y el tratamiento estadístico de los datos nos permitió obtener los siguientes Resultados: los profesores extranjeros que se encuentran en UNB son originarios, en su mayoría, de los países de América Latina y de Europa, son blancos o de color, son doctores y están contratados a tiempo completo y dedicación exclusiva. También intervienen en tareas de investigación y extensión. Estos docentes encuentran grandes dificultades de adaptación a sus lugares de trabajo debido a la falta de mecanismos de socialización y de ayuda en sus prácticas pedagógicas. A la luz de la complejidad del paradigma de Edgar Morin, se puede afirmar que el profesor extranjero sobrevive en la Universidad Pública Brasileña en medio de dilemas y contradicciones tales como problemas culturales, de alteridad y de aceptación por parte de los estudiantes, su inserción en la propia universidad es la busca permanente de medios para poder conectar. Sin embargo, debemos destacar la gran contribución de estos profesores a la calidad de los programas de grado y la inserción internacional de las universidades.This paper fruit of a doctorate thesis in education aimed to understand the foreign teacher, its profile, difficulties, contributions permanence challenges and reconstruction of didactic-pedagogical practices and for its professional exercise in the brazilian public universities.

Our universe was the UnB, federal public university of Brasilia where we found the bigger number of these teachers. Using the INEP data (micro data of census of higher education, 2011) we could localize those ones. Questionnaires were applied to more than 37,3% of the nationalities present (19 of 51 nationalities) corresponding to 7,6% of the population estimated to 250 teachers, documents consulting (school websites, personnel website, photocopy services). The qualitative analysis and the statistical data treatment allowed us to obtain the following results: the teachers met at UnB are from Latin America and Europe, are white or brunet, are doctors and are contracted full time. They also act in teaching, research and extension. These teachers met many adaptation difficulties in their workplace due to a lack of socialization and help mechanisms in their teaching practices. By means of the complexity paradigm of Edgar Morin, we could confirm that the foreign teacher survive in the Brazilian public university within dilemmas and contradictions like cultural problems, alterity and acceptation by the students, its insertion in the own university and is always in search for means to connect the parts. Although, we could note the big contributions of these teachers in the quality of the graduate programs and the international insertion of their universities.Esse trabalho, fruto de uma tese de doutorado em educação buscou apreender o professor estrangeiro, no seu perfil, suas dificuldades, suas contribuições e desafios para a permanência e reconstrução das práticas didático-pedagógicas e para a atuação como profissional docente nas universidades públicas brasileiras.

Preliminary Limits on the WIMP-Nucleon Cross Section from the Cryogenic Dark Matter Search (CDMS)

We are conducting an experiment to search for WIMPs, or weakly-interacting massive particles, in the galactic halo using terrestrial detectors. This generic class of hypothetical particles, whose properties are similar to those predicted by extensions of the standard model of particle physics, could comprise the cold component of non-baryonic dark matter. We describe our experiment, which is based on cooled germanium and silicon detectors in a shielded low-background cryostat. The detectors achieve a high degree of background rejection through the simultaneous measurement of the energy in phonons and ionization. Using exposures on the order of one kilogram-day from initial runs of our experiment, we have achieved (preliminary) upper limits on the WIMP-nucleon cross section that are comparable to much longer runs of other experiments.Comment: 5 LaTex pages, 5 eps figs, epsf.sty, espcrc2dsa2.sty.

Cancer and thrombosis: Managing the risks and approaches to thromboprophylaxis

Patients with cancer are at increased risk of venous thromboembolism (VTE) compared with patients without cancer. This results from both the prothrombotic effects of the cancer itself and iatrogenic factors, such as chemotherapy, radiotherapy, indwelling central venous devices and surgery, that further increase the risk of VTE. Although cancer-associated thrombosis remains an important cause of morbidity and mortality, it is often underdiagnosed and undertreated. However, evidence is accumulating to support the use of low-molecular-weight heparins (LMWHs) in the secondary prevention of VTE in patients with cancer. Not only have LMWHs been shown to be at least as effective as coumarin derivatives in this setting, but they have a lower incidence of complications, including bleeding, and are not associated with the practical problems of warfarin therapy. Furthermore, a growing number of studies indicate that LMWHs may improve survival among patients with cancer due to a possible antitumor effect. Current evidence suggests that LMWHs should increasingly be considered for the long-term management of VTE in patients with cancer

Effect of Dietary Components on Larval Life History Characteristics in the Medfly (Ceratitis capitata: Diptera, Tephritidae)

Background: The ability to respond to heterogenous nutritional resources is an important factor in the adaptive radiation of insects such as the highly polyphagous Medfly. Here we examined the breadth of the Medfly’s capacity to respond to different developmental conditions, by experimentally altering diet components as a proxy for host quality and novelty. Methodology/Principal Findings: We tested responses of larval life history to diets containing protein and carbohydrate components found in and outside the natural host range of this species. A 40% reduction in the quantity of protein caused a significant increase in egg to adult mortality by 26.5%±6% in comparison to the standard baseline diet. Proteins and carbohydrates had differential effects on larval versus pupal development and survival. Addition of a novel protein source, casein (i.e. milk protein), to the diet increased larval mortality by 19.4%±3% and also lengthened the duration of larval development by 1.93±0.5 days in comparison to the standard diet. Alteration of dietary carbohydrate, by replacing the baseline starch with simple sugars, increased mortality specifically within the pupal stage (by 28.2%±8% and 26.2%±9% for glucose and maltose diets, respectively). Development in the presence of the novel carbohydrate lactose (milk sugar) was successful, though on this diet there was a decrease of 29.8±1.6 µg in mean pupal weight in comparison to pupae reared on the baseline diet. Conclusions: The results confirm that laboratory reared Medfly retain the ability to survive development through a wide range of fluctuations in the nutritional environment. We highlight new facets of the responses of different stages of holometabolous life histories to key dietary components. The results are relevant to colonisation scenarios and key to the biology of this highly invasive species

Enhanced mitochondrial superoxide scavenging does not Improve muscle insulin action in the high fat-fed mouse

Improving mitochondrial oxidant scavenging may be a viable strategy for the treatment of insulin resistance and diabetes. Mice overexpressing the mitochondrial matrix isoform of superoxide dismutase (sod2(tg) mice) and/or transgenically expressing catalase within the mitochondrial matrix (mcat(tg) mice) have increased scavenging of O2(˙-) and H2O2, respectively. Furthermore, muscle insulin action is partially preserved in high fat (HF)-fed mcat(tg) mice. The goal of the current study was to test the hypothesis that increased O2(˙-) scavenging alone or in combination with increased H2O2 scavenging (mtAO mice) enhances in vivo muscle insulin action in the HF-fed mouse. Insulin action was examined in conscious, unrestrained and unstressed wild type (WT), sod2(tg), mcat(tg) and mtAO mice using hyperinsulinemic-euglycemic clamps (insulin clamps) combined with radioactive glucose tracers following sixteen weeks of normal chow or HF (60% calories from fat) feeding. Glucose infusion rates, whole body glucose disappearance, and muscle glucose uptake during the insulin clamp were similar in chow- and HF-fed WT and sod2(tg) mice. Consistent with our previous work, HF-fed mcat(tg) mice had improved muscle insulin action, however, an additive effect was not seen in mtAO mice. Insulin-stimulated Akt phosphorylation in muscle from clamped mice was consistent with glucose flux measurements. These results demonstrate that increased O2(˙-) scavenging does not improve muscle insulin action in the HF-fed mouse alone or when coupled to increased H2O2 scavenging

Genetic characterization of morphologically variant strains of Paracoccidioides brasiliensis

Molecular characterization of Paracoccidioides brasiliensis variant strains that had been preserved under mineral oil for decades was carried out by random amplified polymorphic DNA analysis (RAPD). On P. brasiliensis variants in the transitional phase and strains with typical morphology, RAPD produced reproducible polymorphic amplification products that differentiated them. A dendrogram based on the generated RAPD patterns placed the 14 P. brasiliensis strains into five groups with similarity coefficients of 72%. A high correlation between the genotypic and phenotypic characteristics of the strains was observed. A 750 bp-RAPD fragment found only in the wild-type phenotype strains was cloned and sequenced. Genetic similarity analysis using BLASTx suggested that this RAPD marker represents a putative domain of a hypothetical flavin-binding monooxygenase (FMO)-like protein of Neurospora crassa.FiocruzBritish Council Progra
