Avaliação preliminar de genótipos de mandioca em solos sob vegetação de cerrados do Piauí.

Este trabalho tem como objetivos principais: introduzir e selecionar genotipos de mandioca em diferentes mesorregioes, com alto potencial produtivo, associados a elevada percentagem de amido nas raizes para serem recomendados aos produtores de farinha, goma ou tapioca; identificar genotipos com alto potencial de producao de parte aerea, visando sua utilizacao na alimentacao animal.bitstream/item/97589/1/PAND860001.pd

Detection and discrimination of microorganisms using Locked Nucleic Acid - Fluorescence In Situ Hybridization (LNA-FISH)

The impact of multispecies biofilms on catheter-associated urinary tract infections outcome is still unclear due to the lack of adequate methodologies to discriminate the populations in situ. Employing fluorescence in situ hybridization (FISH) to discriminate the populations in a biofilm, can contribute to the understanding of microorganisms interactions in this structures. Consequently, this information might help to develop efficient strategies to prevent this disease. This work presents the first study that apply the FISH methodology using a set of LNA and/2’-O-Methyl RNA oligonucleotide probes, for the in situ detection of microorganisms in biofilms formed under conditions similar to the catheter-associated urinary tract infections

Resistance of legionella pneumophila and helicobacter pylori to chlorination in drinking water biofilms

The disintegration of concrete structures made of ordinary Portland cement (OPC) is a worrying topic of increasing significance. The development of new binders with longer durability is therefore needed. Alkali-activated binders have emerged as an alternative to OPC binders, which seems to have superior durability and environmental impact. This paper reviews current knowledge about alkali-activated binders. The subjects of Part 1 in this paper are historical background, terminology and hydration products. The proper terminology to designate these new binders will be discussed. The influence of the prime materials and the type of alkaline activator on the reaction mechanisms and on the nature of the reaction products will be described
