Integração de dados georreferenciados no mapeamento dos biótopos do gafanhoto praga do Mato Grosso.

Divulga os resultados do projeto, realizado em parceria com o PRIFAS (França), sobre os gafanhotos do Estado do Mato Grosso, particularmente a espécie Rhammatocerus schistocercoides (Rehn, 1906) (Acrididae, Gomphocerinae). O conhecimento sobre sua bioecologia e sobre o determinismo de suas populações era muito limitado, sendo restrito o número de publicações científicas sobre o assunto. As informações encontravam-se, sobretudo, nos relatórios de instituições de pesquisa e de controle fitossanitário nacionais e internacionais, assim como em numerosos artigos de jornais e de revistas. Após três anos de pesquisas, com financiamento aprovado pelo Programa de Cooperação Científica Brasil e CCE, os resultados obtidos já permitem uma idéia bem mais clara do fenômeno, além de inferências sobre as potencialidades e adequabilidade de uso do sensoriamento remoto e do geoprocessamento para abordagens de problemas entomológicos em grande escala

Isolation of Root Endophytic Bacteria in Elephant Grass (\u3cem\u3ePennisetum purpureum\u3c/em\u3e Schum.) Cultivars

Elephant grass (Pennisetum purpureum Schum.) is one of the most productive warm-season grasses. Farmers utilize elephant grass in different forms, such as cut-and-carry operations, grazing, conserved forage (silage, hay), and as an energy source (Lira et al. 2010). Nitrogen (N) is an essential element for plant growth and development and it is usually a limiting factor for forage production in the tropics (Boddey et al. 2004). Biological N fixation (BNF) may occur in warm-season grasses by their association with diazotrophic bacteria. These bacteria colonize different niches in the host plant. Endophytic bacteria form colonies inside the plant tissue whereas epiphytic bacteria colonize plant external surfaces (Compant et al. 2010). Both types of bacteria may benefit host plants (Badri et al. 2009). This study evaluated endophytic diazotrophic bacteria density associated to the roots of different elephant grass cultivars (cvs. ‘Elefante B’, ‘Venezuela’, and ‘Pioneiro’) using two N-free growth media, at different evaluation periods

Are Posture Data from Simulated Tasks Representative of Field Conditions? Case Study for Overhead Electric Utility Workers

Many ergonomics studies are conducted in laboratory-simulated work environments to assess risks for the development of musculoskeletal disorders under more controlled conditions. However, the simulated conditions could be of questionable validity with respect to reproduction of field conditions involving risk factors. The objective of this study was to verify whether the postures recorded for neck extension/flexion and upper arm elevation of overhead electric utility workers in a simulated environment were similar to those recorded in a field environment. Of the three frequently performed tasks analysed, two presented similar exposure in both conditions. However, differences were identified for a more complex task (relay replacement). These results suggest that simulated tasks may be more representative for more standardised tasks. This may indicate that researchers investigating risks should avoid simplifying complex tasks when reproducing field posture exposure in laboratories, since omitting extra subtasks may lead to an inaccurate reproduction of field exposure. Practitioner Summary: Studies comparing results from field and simulated environments are necessary to evaluate to what degree postural exposure reproduced in laboratory is representative of the exposure occurring in real work situations. This is particularly relevant for tasks involving training in simulated environment due to safety constraints

Os primeiros anos da Universidade Federal do Pará vistos através da Faculdade de Medicina.

O trabalho pretende apresentar as disputas entre grupos divergentes durante a criação da Universidade do Pará e os problemas da primeira reitoria, sob a ótica da Faculdade de Medicina, que representava uma força importante nesse período dentro do ensino superior do estado. Os conflitos existentes nos primórdios da instituição são tradicionalmente desconsiderados em abordagens mais convencionais

Resultado do tratamento operatório do aneurisma da aorta abdominal roto contido crônico: estudo caso-controle

OBJECTIVE: To establish, in a case-control study, the early mortality and long-term survival after surgical correction of sealed rupture abdominal aortic aneurysm, compared to controls who underwent standard, nonruptured abdominal aortic aneurysm repair. PATIENTS AND METHODS: From January 1992 to December 2002, 465 patients underwent infrarenal abdominal aortic aneurysm repair. Of those, 13 had sealed rupture abdominal aortic aneurysm (2.8%). These cases were compared to 26 controlsin which surgical repair was performed immediately preceding or succeeding each one of the sealed rupture abdominal aortic aneurysm surgeries. RESULTS: Age, sex, risk factors for atherosclerosis, associated disease, and cardiac ischemia were similar between groups. Patients with sealed rupture abdominal aortic aneurysm presented a higher incidence of lumbar pain than controls (92.3% versus 3.9%; P < .001); fever and weight loss were detected in 5 (38.5%) patients with SAAA and in none of controls (P = .0022). Mean red blood cell transfusion was greater for sealed rupture abdominal aortic aneurysm than controls (1,516 &plusmn; 697 vs. 773 &plusmn; 463 mL (P = .0003). Postoperative complications were similar between groups. Early mortality was 7.7% for sealed rupture abdominal aortic aneurysm and 0% for controls. Five-year survival was significantly lower for sealed rupture abdominal aortic aneurysm (68.4%) than for controls (84.4%, P = .04). CONCLUSION: We conclude that sealed rupture abdominal aortic aneurysm presents diagnostic and surgical challenges that can be adequately managed, achieving early postoperative mortality and complication rates that are similar to standard abdominal aortic aneurysm. However, patients with sealed rupture abdominal aortic aneurysm present higher mortality in the long term compared with patients having standard abdominal aortic aneurysm.OBJETIVO: Estabelecer, através de um estudo caso-controle, a mortalidade precoce e sobrevida a longo prazo após o tratamento cirúrgico do aneurisma da aorta abdominal roto contido crônico comparada aos respectivos controles, submetidos ao reparo do aneurisma da aorta abdominal não roto, operado eletivamente. PACIENTES E MÉTODO: De Janeiro de 1992 a Dezembro de 2002, 465 pacientes foram submetidos ao reparo de aneurismas da aorta abdominal. Destes, 13 eram aneurisma da aorta abdominal roto contido crônico (2,8%), que foram comparados a 26 controles nos quais a correção eletiva do aneurisma ocorreu imediatamente antes e após a correção do aneurisma da aorta abdominal roto contido crônico. RESULTADO: Não houve diferença entre os grupos com relação a idade, sexo, fatores de risco para aterosclerose, doenças associadas e cardiopatia isquêmica. Pacientes com aneurisma da aorta abdominal roto contido crônico apresentaram maior incidência de dor lombar (92,3% versus 3,9%;

A Spectral Bernstein Theorem

We study the spectrum of the Laplace operator of a complete minimal properly immersed hypersurface $M$ in $\R^{n+1}$. (1) Under a volume growth condition on extrinsic balls and a condition on the unit normal at infinity, we prove that $M$ has only essential spectrum consisting of the half line $[0, +\infty)$. This is the case when $\lim_{\tilde{r}\to +\infty}\tilde{r}\kappa_i=0$, where $\tilde{r}$ is the extrinsic distance to a point of $M$ and $\kappa_i$ are the principal curvatures. (2) If the $\kappa_i$ satisfy the decay conditions $|\kappa_i|\leq 1/\tilde{r}$, and strict inequality is achieved at some point $y\in M$, then there are no eigenvalues. We apply these results to minimal graphic and multigraphic hypersurfaces.Comment: 16 pages. v2. Final version: minor revisions, we add Proposition 3.2.

Avaliação integrada da curva de permanência da vazão fluvial e da carga de fósforo em bacia hidrográfica rural: Integrated evaluation of the cumulative frequency curve of the flow and phosphorus load in a watershed basin

A análise conjunta da curva de permanência de qualidade e quantidade da água são importantes ferramentas de auxílio ao gerenciamento de recursos hídricos, pois mostra em quanto um determinado parâmetro é igualado ou superado frente ao enquadramento proposto, facilitando assim a verificação do cumprimento da legislação ambiental. Neste estudo é apresentado uma abordagem das curvas de permanência de dados de vazões (2010 a 2018) e de fósforo total (2004 a 2018) no rio Rio Fragoso. Através das curvas de permanência de fósforo e de vazão fluvial constatou-se que em diversos momentos do monitoramento a concentração de fósforo permitida fica acima do limite estabelecido pela Resolução CONAMA 357/2005, para o referido rio em estudo
