Abstract: Resumo.- A vegeta o da caatinga apresenta grande potencial de produ o de forragem constituindo na maioria das vezes a principal fonte de alimenta o animal na regi o semi-árida no Nordeste brasileiro. As espécies forrageiras dessa vegeta o apresentam oscila es periódicas de crescimento e de flora o, havendo, entretanto, muita dúvida sobre os fatores que afetam esta periodicidade. O crescimento das plantas pode ser avaliado a partir da estimativa da área foliar, sendo comumente utilizada em estudos agron micos. Dos fatores do ambiente que mais afetam o crescimento das plantas destaca-se o déficit hídrico, cuja resposta mais comum das plantas é a redu o da produ o da área foliar, fechamento dos est matos, acelera o da senescência e abscis o das folhas. Assim esta revis o teve como objetivo discutir sobre aspectos relacionados ao potencial forrageiro da caatinga, enfatizando a importancia dos estudos da fenologia, dos métodos de avalia o da área foliar e o efeito do déficit hídrico sobre o crescimento das plantas. Abstract.- The vegetation of caatinga presents great potential of fodder plant production constituting in the majority of the times the main source of animal feeding in the half-barren region in the Brazilian Northeast. The forage species of this vegetation present periodic oscillations of growth and budding, having, however, much doubt on the factors that affect this regularity. The growth of the plants can be evaluated from the estimate of the foliar area, being commonly used in agronomy studies. Of the factors of the environment that more affect the growth of the plants is distinguished the hidric deficit, whose more common reply of the plants it is the reduction of the production of the leaf area, closing of the stomat, acceleration of the senescence and fall of leaf. Thus this revision had as objective to argue on aspects related to the forage potential of caatinga, emphasizing the importance of the studies of the phenology, the methods of evaluation of the leaf area and the effect of the hidric deficit on the growth of the plants.

Abstract: surface cleaning is a well-known control procedure against the dissemination of microorganisms in the hospital environment. this prospective study, carried out in an intensive care unit over the course of 14 days, describes the cleaning/disinfection conditions of four surfaces near patients. in total, 100 assessments of the surfaces were carried out after they were cleaned. three methods were used to evaluate cleanliness: a visual inspection, an adenosine triphosphate (atp) bioluminescence assay and testing for the presence of staphylococcus aureus and meticillin-resistant staphylococcus aureus/mrsa. respectively, 20%, 80% and 16% of the assessments by the visual method, atp and the presence of staphylococcus aureus/mrsa failed. there were statistically significant differences (p<0.05) between the rates of failure of the cleaning using the atp method, compared to the visual and microbiological methods. the visual inspection was not a reliable measure to evaluate surface cleanliness. the results demonstrated that the adopted cleaning routine should be reconsidered.

Abstract: Com base na ideologia da sustentabilidade, o governo federal vem empregando no seu discurso o termo gest o sustentável, como norteador de uma práxis atual na atividade pesqueira no Brasil, que enfrenta uma crise sem precedentes devido ao uso contínuo de métodos de pesca predatórios, amea ando tanto as espécies marinhas como o sustento de uma gera o de pescadores artesanais e seu legado cultural. Sem pretens o de esgotar o assunto e com base em alguns autores da Escola Francesa de Análise de Discurso (AD), este artigo prop e uma reflex o teórica de como a linguagem é materializada na ideologia e como esta se manifesta na linguagem. Para tanto, analisa-se o discurso da sustentabilidade, o discurso da propaganda e, ainda, o discurso do poder na campanha Proteger a Lagosta é Proteger o Pescador lan ada em 2007 pela Secretaria Especial de Aqüicultura e Pesca – SEAP e pelo Ministério do Meio Ambiente - Ibama. O presente trabalho situa-se nos condicionantes sócio-históricos contemporaneos, a partir da cria o da SEAP, em 2003, e tem uma abordagem crítica sobre o discurso institucional da campanha em quest o, que ora é ideológico e encontra justificativa na gest o sustentável da lagosta, como uma política pública para recuperar a atividade no país, ora é um discurso de poder que, através de uma campanha de constru o social, institui medidas e regras para a pesca da lagosta.

Abstract: Trata-se de um desdobramento de um projeto de disserta o de mestrado, que teve como objetivo analisar o sofrimento dos trabalhadores de enfermagem em fun o do aumento da jornada de trabalho, do multiemprego e/ou das escalas extras de trabalho e das condi es de trabalho no cotidiano desses trabalhadores em um hospital público de Natal/RN. A metodologia foi pautada em um estudo descritivo com abordagem qualitativa. Utilizou-se como técnica de coleta de informa es a entrevista individual guiada por um roteiro com quest es abertas e semi-estruturadas. O período correspondeu aos meses de julho e agosto de 2003. Na análise dos dados, as entrevistas transcritas foram organizadas de acordo com o grupo a que pertencia, foi realizada uma leitura exaustiva dos textos para o agrupamento de informa es com características comuns. Cada unidade de registro foi sendo agrupada de acordo com categorias empíricas que surgiram durante o processo. A análise das informa es foi realizada com base em elementos do método dialético. Os resultados encontrados apontam para a existência de um sentimento de vazio e fragiliza o dos la os afetivos com familiares; conflitos de valores referentes à rela o ser/ter; vivência de ansiedade e estresse pelo sentimento de impotência vivenciado no cotidiano de trabalho; o sentimento de aprisionamento e perda dos sonhos decorrente do acúmulo de jornadas de trabalho; reconhecimento da transversalidade do sofrimento sob a ótica de gênero. Conclui-se portanto que o aumento da jornada de trabalho está trazendo aos trabalhadores desgaste físico, emocional e sofrimento no cotidiano somando-se à precariedade das condi es de trabalho, gerando insatisfa o do trabalhador, comprometendo a assistência prestada, assim como, dificultando as rela es interpessoais no ambito das dimens es públicas e privadas da vida cotidiana.

Abstract: Objective: Evaluate the sealing conditions of adhesive restorations after the chemomechanical removal of carious tissue with a papain gel (Papacarie ) and after the traditional method of caries removal utilizing rotatory instruments. Method: Seventeen human premolars with caries lesions envolving oclusal (enamel marginal) and cervical (dentin marginal) surfaces was used. The sample was divided in two groups: G1 removal of caries tissue with the traditional method G2 removal of caries tissue with the chemomechanical technique (Papacarie ). After the removal of caries tissue with one of the two techniques, the adhesive system Prime&Bond 2.1 was applied and the cavities were restored with composite resin (Filtek Z250 , A2). The test specimes were thermocycled (300 cycles at 5oC – 55oC, for 15 seconds in each temperature), isolated through the sealing of apices, immersed into basic fucsin during 24 hours, seccioned longitudinally through the restoration and assessed by three examiners that attributed marks according to the degree of dye penetration along the interface enamel/restoration and dentin/restoration in occlusal and cervical wall, respectively. Results: The statistical analysis using the Mann-Whitney test revealed the occurrence of marginal microleakage in both groups (Papacarie and rotatory instruments) when the cervical surface was evaluated and there was no significant difference between them. Nevertheless, when the oclusal surface was evaluated there was a significant difference between the groups, because in Papacarie’s group had worst results. Conclusion: The sealing properties of composite resin restorations were harmed by the method of caries removal with Papacarie .

Abstract: the acute renal failure (arf), that still presents a righ mortality rate (50%) can be defined as an abrupt decline of the glomerular filtration, resultant of isquemic or toxicity event. the drugs nephrotoxicity is one of the most frequent cause (27%) of arf and it is suggested that the interval of administration of the drug can interfere in this side effect, however the best administration regimen is not very well established. this study evaluated the renal function of rats that received gentamicin (100mg/kg) in one dose or in two doses (2x 50mg/kg),by intraperitoneal infusion. the results obtained in this research, indicated that the single infusion of gentamicin determined smaller nephrotoxicity by the reduction of serum concentration of this drug in 24 hours, decreasing the intracelular accumulation of this gentamicin, which is one of the main cellular mechanisms of this renal injury. the single dose treatment regime, otherwise, showes advantages not only related to the nephrotoxicity effect, but also it is relevant to the cost and safety, which can be rationable factors in the administration of this drug.
