Este estudio investiga el grado de incidencia de estrés laboral (Lazarus y Folkman, 1984; Jesús, 2005) en una muestra de profesores en la Educación Básica e Secundaria, oficiales, de la isla de Madeira, mediante el estudio de las variables afrontamiento (Latack, 1986; Jesus & Pereira, 1994) y auto-eficacia (Bandura, 1997). Los encuestados fueron 765 docentes del 1º, 2º, 3º Ciclo de Educación Básica y Educación Secundaria. Para evaluar las variables de estudio, se utilizó el cuestionario sobre el estrés docente (Gomes, 2007), el Coping Job Scale de Latack (1986) adaptado por Jesus y Pereira (1994) y el cuestionario de autoeficacia del personal docente (Pedro, 2007). Los resultados obtenidos sugieren las siguientes conclusiones: la percepción de altos niveles de estrés en el trabajo (42% de los profesores); las fuentes de estrés más perturbadoras son la mala actitud de los estudiantes y las correspondientes medidas de intervención inadecuadas; los factores situacionales inherentes a el contenido funcional y la sobrecarga de trabajo están causando estrés y malestar en los profesores; los maestros se basan principalmente en las estrategias de control; los profesores revelan percepciones de autoeficacia alta (3,60); existe una asociación positiva entre la percepción de estrés en la enseñanza y las estrategias de control; existe una asociación entre la autoeficacia general y las estrategias de control; existe una asociación entre la percepción de autoeficácia general y el nivel global de estrés percibido; y se detectó varios diferencias significativas en función de las variables sociodemográficas y profesionales. Este trabajo sugiere la capacidad predictiva de las dimensiones de la autoeficacia como variable moderadora cuando, al mismo tiempo, articula con el coping y las variables sociodemograficas profesionales, en estrés docente.

The gas migration during the cementing of wells is one of the main problems of oil wells engineering. Its occurrence can cause severe problems since shortly to loss of control of the well after cementation. Recently, 20/04/2010 In an accident of major proportions in the Gulf of Mexico, among other factors, faulty cementing operation provided the gas migration, causing the accident, in which 11 people died and 17 were injured occurred. Besides the serious consequences that can be caused by gas migration, remediation of the problem, which is made by injecting cement in damaged areas, usually involves additional costs and is not always effective. Therefore, preventing gas migration to be preferred. Some methods are used to prevent the migration of the pressurized gas as the annular space, application of pressure pulses, reducing the height of the cement column compressible cement pastes of low permeability, pastes and to control free filtered water, and binders of thixotropic cement expandable and flexible. Thus, the cement pastes used to prevent gas migration must meet the maximum these methods. Thus, this study aimed to formulate a cement paste to prevent gas migration, using the expanded vermiculite, and evaluate the behavior of the folder trials necessary for use in oil wells. Free water content, rheological properties, compressive strength, loss of liquid phase sedimentation of solids, specific weight, thickening time and gas migration: The following tests were performed. The results show that meets the specifications paste formulated for use in oil wells and the use of expanded vermiculite contribute to the absorption of free water, thixotropy and low density. The absorption of free water is proven to result in zero percentage test free water content, thixotropy is observed with the high value of the initial gel strength (Gi) in testing rheological properties and low density is proven in test weight specific

This project has resulted from a reunion between me and two teachers with whom I had already worked, pedagogically counseling them during the execution of the Project of Youngsters and Adults Schooling at the Agrarian Reform Settlements in the State of Sergipe (PAJA/PRONERA) between 2002 and 2003. The matter that really motivated the research was related to the essential principle that guided the accomplishment of the PAJA s teachers education and professionalization: understanding their reality and knowing their needs, promoting the dialogue between scientific and common sense knowledge. Taking as a reference the fact that the teachers education is not restricted to the academic qualification, that is, that it is a part of the educational process, which, in turn, is a result of each one s personal background, dialectically individual and collective, the access to the teachers reality and needs was accomplished by studying their backgrounds, especially their school and professional career. They, inevitably, focused themselves on the country life s social and cultural context, that could be better understood by living together with the teachers during the twenty-seven days I stayed in the Golfo s settlement, located in the town named Pacatuba/SE. The approach to the teachers lives through their stories and the daily contact proved how much Science is still distant from the peasants routine, sometimes being presented to them as a finished product . That way, the dialog between those two categories and the expectation of the country life s social and cultural conditions, together with the education, in which teachers have an essential role, still remain as a challenge

The infographics historically experience the process of evolution of journalism, from the incipient models handmade in the eighteenth century to the inclusion of computers and sophisticated software today. In order to face the advent of TV against of the partiality readers of the printed newspaper, or to represent the Gulf War, where not allowed photography, infographics reaches modern levels of production and publication. The technical devices which enabled the infographics to evolve the environment of the internet, with conditions for the manipulation of the reader, incorporating video, audio and animations, so styling of interactive infographics. These digital models of information visualization recently arrived daily in the northeast and on their respective web sites with features regionalized. This paper therefore proposes to explore and describe the processes of producing the interactive infographics, taking the example of the Diário do Nordeste, Fortaleza, Ceará, whose department was created one year ago. Therefore, based on aspects that guide the theory of journalism, as newsmaking, filters that focus on productive routine (gatekeeping) and the construction stages of the news. This research also draws on the theoretical framework on the subject, in concepts essential characteristics of computer graphics, as well as the methodological procedures and systematic empirical observations in production routines of the newsroom who can testify limitations and / or advances

Os autores relatam cinco acidentes de seabather's eruption ou prurido do traje de banho, uma erupção típica associada na maioria das vezes à água-viva Linuche unguiculata (Cnidaria), que causa um rash pápulo-eritematoso extremamente pruriginoso em áreas cobertas por trajes de banho. O quadro cutâneo é característico e a erupção é comum no Caribe, Flórida, México e estados americanos do Golfo. Os casos são os primeiros relatados no Brasil e larvas de Linuche unguiculata estão presentes nas águas onde ocorreram os acidentes.

Red snappers (Lutjanus purpureus in Brazil and Lutjanus campechanus in USA and Gulf of Mexico) are both under clear effect of overfishing. Because of their high morphological similarity it has already been suggested that they could possibly be considered as a single species. To investigate the degree of similarity and the genetic structure of red snapper populations we constructed a common dataset of partial D-loop mtDNA sequences of L. purpureus from Brazil (Amapá, Pará and Maranhão) and L. campechanus from the Atlantic coast of the USA (Florida, Louisiana and Mississippi). Phylogenetic and population genetic analyses surprisingly depicted high similarity between L. campechanus and L. purpureus, compatible with the hypothesis of a single species of red snapper for the Western Atlantic Ocean. These preliminary but very curious findings open an important discussion regarding the legislation involved on the capture of this overexploited fish resources as well as regarding their taxonomy.

Lacaziose ou doença de Jorge Lobo é micose crônica, granulomatosa, causada por implantação traumática do fungo Lacazia loboi – patógeno não cultivável até o presente – nos tecidos cutâneo e subcutâneo, manifestando-se clinicamente por lesões nodulares queloidianas predominantes, envolvendo sobretudo pavilhões auriculares, face, membros superiores e inferiores, e não comprometendo as mucosas. A maioria dos casos humanos está registrada em países da América do Sul. Entretanto, a enfermidade apresenta aspectos epidemiológicos destacados, como o aparecimento em tribo Caiabi, no Brasil Central e em mamíferos não humanos, golfinhos de duas espécies (Tursiops truncatus e Sotalia guianensis) capturados na costa da Flórida (EUA), na foz do rio Suriname, na costa de Santa Catarina (Brasil), no golfo de Gasconha (baía de Biscaia-Europa), com manifestações cutâneas e achados histopatológicos muito similares às encontradas no homem. O artigo objetiva abordar características do fungo e sua taxonomia, e aspectos históricos, ecoepidemiológicos, clínicos, imuno-histoquímicos, histopatológicos, ultra-estruturais e terapêuticos.

Scomberomorus cavalla é uma espécie de peixe pelágico amplamente distribuído na costa oeste do Atlântico, e uma diminuição no seu nível de captura tem sido verificada nos E.U.A e Golfo do México, comparada com os níveis alcançados pela espécie no passado. Da mesma forma, em algumas áreas do Brasil, há indícios de sobre-exploração. Entretanto, não existem estudos moleculares que visam o manejo deste importante item. Desta forma, no presente estudo, foram seqüenciados 380 pares de bases nucleotídicas da região da Alça-D do DNA mitocondrial de amostras provenientes de desembarque em Macapá, Bragança e Fortaleza. As análises filogenéticas e populacionais revelaram que há apenas uma população panmítica e baixos níveis de variabilidade genética foram observados. Estes resultados, assim como a observada sobre-exploração de S. cavala, representam dados muito importantes para o estabelecimento do manejo deste estoque a fim de prevenir um colapso ou risco de extinção no futuro.
