Densidade de oviposição, e quantificação de Larvas e Pupas de Mansonia Blanchard, 1901 (Diptera: Culicidae), em Eichhornia crassipes Solms. e Pistia stratiotes Linn. Na ilha da Marchantaria, Amazônia Central

A população de imaturos de Mansonia em águas brancas da várzea da ilha da Marchantaria, na Amazônia Central se constituiu de 74% de Mansonia (M.) humeralis Dyar & Knab, 1916, 14% de Mansonia (M.) titillans (Walker, 1848) e 12% de Mansonia (M.) amazonensis Theobald, 1901, como foi indicado pela frequência, medida por oviposição (posturas). O número de posturas de M. humeralis e M. titillans foi maior em Pistia stratiotes Linn. enquanto que M. amazonensis foi mais abundante em Eichhornia crassipes Solms. O número total de larvas e pupas de Mansonia spp. foi de 6997 e 570 respectivamente, sendo maior em E. crassipes (4372 e 328) que em P. stratiotes (2625 e 242). Ao longo do ano, o maior número de larvas e pupas foi encontrado nos meses da vazante (agosto-outubro), tendo um pico no mês de agosto, que não foi correlacionado significativamente com os fatores abióticos.

Cinética da secagem de clones de café (Coffea canephora Pierre) em terreiro de chão batido

Objetivou-se com o presente trabalho estudar a cinética da secagem de quatro clones de café da espécie Coffea canephora submetidos à secagem em terreiro de chão batido, bem como ajustar diferentes modelos matemáticos aos valores experimentais selecionando aquele que melhor representa o fenômeno em estudo. Foram utilizados frutos de café dos clones: Cpafro 194, Cpafro 193, Cpafro 167 e Cpafro180, colhidos com os teores de água iniciais de 1,20; 1,32; 1,51 e 1,46 (decimal base seca (b.s.)), respectivamente. A secagem prosseguiu em terreiro de chão batido até que o produto atingisse o teor de água de 0,137; 0,133; 0,142 e 0,140 (decimal b.s.) respectivamente para os clones Cpafro 194, Cpafro 193, Cpafro 167 e Cpafro 180. Aos dados experimentais foram ajustados dez modelos matemáticos citados na literatura específica e utilizados para representação do processo de secagem de produtos agrícolas. Baseando-se em parâmetros estatísticos, conclui-se que os modelos Verma, Dois Termos e Aproximação da Difusão foram adequados para representação da secagem dos quatro clones de café analisados, e além destes, para o clone Cpafro 167, os modelos Thompson, Page, Newton, Logarítmico, Henderson e Pabis e Exponencial de Dois Termos também se mostraram satisfatórios na descrição do fenômeno; já o tempo necessário para a secagem em terreiro de chão batido dos clones de café Cpafro 194, Cpafro 193, Cpafro 167 e Cpafro 180 foi de 189,5 h.

Pulmonary Embolism Mortality in Brazil from 1989 to 2010: Gender and Regional Disparities

Abstract Background: A significant variation in pulmonary embolism (PE) mortality trends have been documented around the world. We investigated the trends in mortality rate from PE in Brazil over a period of 21 years and its regional and gender differences. Methods: Using a nationwide database of death certificate information we searched for all cases with PE as the underlying cause of death between 1989 and 2010. Population data were obtained from the Brazilian Institute of Geography and Statistics (IBGE). We calculated age-, gender- and region-specific mortality rates for each year, using the 2000 Brazilian population for direct standardization. Results: Over 21 years the age-standardized mortality rate (ASMR) fell 31% from 3.04/100,000 to 2.09/100,000. In every year between 1989 and 2010, the ASMR was higher in women than in men, but both showed a significant declining trend, from 3.10/100,000 to 2.36/100,000 and from 2.94/100,000 to 1.80/100,000, respectively. Although all country regions showed a decline in their ASMR, the largest fall in death rates was concentrated in the highest income regions of the South and Southeast Brazil. The North and Northeast regions, the lowest income areas, showed a less marked fall in death rates and no distinct change in the PE mortality rate in women. Conclusions: Our study showed a reduction in the PE mortality rate over two decades in Brazil. However, significant variation in this trend was observed amongst the five country regions and between genders, pointing to possible disparities in health care access and quality in these groups.
