Organic Design

practices represent a rich resource for ecologists interested in understanding the mechanisms at work in complex agroecosystems, such as the interactions between biodiversity and ecosystem function or the use of natural succession as templates to design this type of system. It is only recently that ecologists have recognized the virtues of traditional agroecosystems, where sustainability is based on complex ecological models. An examination of the ways these farmers use…

extremely electrophilic and diffuse throughout enamel and dentin matrix to attack the macromolecules of pigments (organic molecules) and acquire stability.7,8 Then, the intrinsic pigments composed by highly unsaturated organic macromolecules are transformed into less complex molecules, which are smaller, simpler and lighter than the original ones.8 However, this reaction is unspecific, and the organic and inorganic matrix of the enamel and dentin might be affected by the bleaching…

The experimental design was randomized block, with three replications in sub-divided plots. The plot was constituted by 32 and the sub-plot by 16 plants, spaced at 1.00 x 0.50 m. In the plots, six levels of cattle manure (0, 10, 20, 30, 40 and 50 t ha-1) were appraised, while in the sub-plots the forms of application of the biofertilizer (with and without application of biofertilizer in the soil and spraying on the leaves) and an additional treatment with mineral and organic…

utilização de células íntegras de B. subtilis apresentou a redução de cetonas a álcoois com alta enantiosseletividade. x Abstract Lipases present an important role in the development of biotechnology and are employed as biocatalysts in organic chemistry with high regio-, quimioand enantioselectivity. Besides allowing more sustainable syntheses that are consistent with the principles of Green Chemistry. The enzymatic resolution of amines has been shown to be an efficient way to…

tecnologia que possibilita contrastes espetaculares. Os televisores normais bons oferecem taxa de contraste de 100.000:1, os mais modernos, com esta tecnologia, oferecem taxas de até 5.000.000:1. São imagens que chegam próximas a perfeição. OLED TV (Organic Light Emitting Diodes): Última novidade em tecnologia para televisão. Formada por uma tela de polímeros, com um material orgânico que emite luz própria ao ser carregado por uma corrente elétrica. Tecnologia desenvolvida a partir dos…
