Visualisation and characterisation of flame radical emissions through intensified spectroscopic imaging

Combustion flames contain strong emissions from excited radical species produced by the combustion process. The monitoring and characterisation of such emissions is important for an in-depth understanding of fuel energy conversion and pollutant formation processes. In this paper, an approach combining emission spectroscopy with intensified digital imaging techniques is proposed for visualising and quantifying the radiative characteristics of free radicals of combustion flames. Recent advances in CCD technology, especially in EM image intensification, have made it possible to obtain high resolution emission images of isolated spectral emissions from particular flame radicals. These can be used to study emission intensity and distribution, with the aim of correlating combustion emission products with flame spectral emission patterns

The influence of land use systems on soil and surface litter fauna in the western region of Santa Catarina.

The aim of this study was to evaluate the abundance of soil and surface litter fauna in the western region of Santa Catarina state, southern Brazil, in the following land use systems (LUS): no-tillage crops (NT), integrated crop-livestock (ICL), pasture (PA), Eucalyptus plantation (EP) and native forest fragments (NF). Sampling was done in three counties in the western region of Santa Catarina: Xanxerê, Chapecó and São Miguel do Oeste, in two seasons (winter and summer). The evaluation of soil/litter fauna in each LUS was performed by installing nine ?pitfall traps? per sampling grid (3 x 3). The counties are true replicas. The soil for the chemical attributes was collected at the same sampling points for soil fauna. Altogether, 17 taxa were identified in the five LUS. The presence of groups of fauna was influenced by the type of soil management used. The LUS NF and EP provide better soil conditions for the development of a higher diversity of soil fauna groups compared to other LUS, which showed varying degrees of human intervention, regardless of the sampling season (winter or summer). However, annual crop systems NT and ICL groups showed greater richness and total abundance when compared to the perennial systems (EP and PA). Principal component analysis is an important tool in the study of biological indicators of sustainability because it allows use of soil attributes (chemical and physical) as explanatory environmental variables, which helps in the interpretation of ecological data.201

Conteúdo de b-glucana em cultivares de aveia-branca cultivadas em diferentes ambientes.

Resumo ? O objetivo deste trabalho foi caracterizar cultivares de aveia-branca quanto ao conteúdo de b-glucana nos grãos, determinar sua relação com a produtividade e o rendimento industrial de grãos, e definir os parâmetros de adaptabilidade e estabilidade para esses caracteres. Nas safras de 2007 e 2008, foram cultivadas 15 cultivares de aveia-branca nos municípios de Augusto Pestana, Capão do Leão e Passo Fundo, no Rio Grande do Sul, seguindo delineamento em blocos ao acaso, com quatro repetições constituídas por parcelas úteis de 3 m2. De maneira geral, os genótipos apresentaram desempenho variável de acordo com a região e o ano de cultivo, para conteúdo de b-glucana no grão. As cultivares Barbarasul, Brisasul, UFRGS 19, UPFA 22, URS 20, URS 22 e URS Guapa apresentam biótipo ideal, com elevado conteúdo médio de b-glucana no grão, ampla adaptabilidade e elevada estabilidade fenotípica. Foram constatadas relações significativas entre o conteúdo de b-glucana no grão e a produtividade e o rendimento industrial de grãos.Made available in DSpace on 2011-04-09T12:53:38Z (GMT).
