Method: A descriptive and analytical study of the Integrative Literature Review type was carried out in national and international databases from the last ten years in the period from 2009 to 2018, concerning 32 studies referring to association between carcinogenic substances to which the worker is exposed and lung cancer. Results: Nine (28.1%) publications originated in China and only one in Brazil. The most exposed workers were from the secondary sector, 50% being from industry and 6.2% from construction, mostly male. Asbestos and silica stood out among the carcinogenic substances most associated with lung cancer risk, accounting for 37.5% and 28.1%, respectively. Conclusions: The association between occupational exposure and the risk for lung cancer was characterized in this research by the substantial scientific evidence from the described...

A identificacao correta do paciente e a monitorizacao de seus sinais vitais, que devem ser realizados antes, apos os primeiros quinze minutos e ao termino da infusao de qualquer hemocomponente sao elementos chave na seguranca transfusional. No curso de Enfermagem do Centro Universitario Autonomo do Brasil o academico tem a oportunidade de trabalhar com projetos assistenciais no âmbito hospitalar. A apresentacao do projeto e um metodo utilizado no processo de ensino aprendizagem do Estagio Curricular Supervisionado II do 8o periodo do curso. O presente projeto justifica-se pela observacao diaria no campo de estagio durante o mes de agosto de fichas de acompanhamento transfusionais incompletas, principal...

Metodo: Estudo descritivo e analitico de revisao integrativa realizada em base de dados nacionais e internacionais dos ultimos dez anos, entre 2009 e 2018, compreendendo 32 estudos referentes a associacao entre câncer de pulmao e substâncias carcinogenicas de exposicao ocupacional. Resultados: Nove (28,1%) publicacoes originadas na China e apenas uma brasileira. Os trabalhadores mais expostos foram do setor secundario, sendo 50% da industria e 6,2% da construcao civil, em sua maioria do sexo masculino. O amianto e a silica sobressairam-se entre as substâncias carcinogenicas mais associadas ao risco de câncer de pulmao correspondendo a 37,5% e 28,1%, respectivamente. Conclusoes: A associacao entre a exposicao ocupacional e o risco de câncer de pulmao ficou caracterizada nesta pesquisa pelas substanciais evidencias cientificas dos estudos ...

A pesquisa foi desenvolvida no Campus José Aloísio de Campos da Universidade Federal de Sergipe. Buscamos identificar quais alunos participam deste tipo de atividade, as contribuições e limitações da realização da pesquisa em ensino de Química durante a formação inicial. A coleta de dados ocorreu durante a disciplina Pesquisa em Ensino de Química I no período 2012/1 através da aplicação de questionário. Observamos que a maioria dos licenciandos apresenta pouco envolvimento com o curso.

Data streams are mapped to cellular organisms defining their structure and behavior as autonomous agents. Network bandwidth drives the growth of each entity and the latency defines its physics-based independent movements. The collection of entity is bound within the 3D representation of the local venue. This visual and animated metaphor allows the public to experience the complexity of high-speed network streams that are used in the scientific community. Moreover, CytoViz displays the presence of discoverable Bluetooth devices carried by nearby persons. The concept is to generate an event-specific, real-time visualization that creates informational 3D patterns based on actual local presence. The observed Bluetooth traffic is put in opposition of the wide-area networking traffic by overlaying 2D animations on top of the 3D world. Each device is mapped to an animation fading over time while displaying the name of the detected device and its unique physical address. CytoViz was publicly presented at two major international conferences in 2005

The New Orleans strain was used as a susceptible control. Mortality rates after a 1 h exposure and after a 24 h recovery period were determined. The resistance ratio between the 50% knockdown values (RR KC50) of the F 1 and New Orleans strains indicated high levels of knockdown resistance. The RR KC50 with ␣-cypermethrin varied from 10 to 100 among strains indicating high levels of knockdown resistance. Most of the strains had moderate resistance to d-phenothrin. SigniÞcant but much lower levels of resistance were detected for-cyalothrin, permethrin, and cypermethrin. For z-cypermethrin and bifenthrin, only one strain exhibited resistance with RR KC50 values of 10-and 21-fold, respectively. None of the strains showed RR KC50 Ͼ10 with deltamethrin, and moderate resistance was seen in three strains, while the rest were susceptible. Mosquitoes from all strains exhibited some recovery from all pyrethroids except d-phenothrin. Regression analysis was used to analyze the relationship between RR LC50 and RR KC50. Both were highly correlated (R 2 ϭ 0.84 Ð 0.97) so that the slope could be used to determine how much additional pyrethroid was needed to ensure lethality. Slopes ranged from 0.875 for d-phenothrin (RR LC50 Ӎ RR KC50) to 8.67 for-cyalothrin (ϳ8.5-fold more insecticide needed to kill). Both RR LC50 and RR KC50 values were highly correlated for all pyrethroids except bifenthrin indicating strong cross-resistance. Bifenthrin appears to be an alternative pyrethroid without strong cross-resistance that could be used as an alternative to the current widespread use of permethrin in Mexico.
