Capillary Electrophoresis ( CE ) : a Powerful Tool to Characterize Humic Acid ( HA ) Solange L

Neste estudo, avaliou-se a possibilidade de eliminação das etapas de purificação envolvidas na caracterização de HA. HA de diferentes fontes foram analisados por CZE apresentando diferentes eletroferogramas. Essas diferenças observadas mostram que a caracterização do HA por CZE depende da carga e do tamanho do HA. Os resultados apresentados neste trabalho sugerem que não é necessária a purifica...

Double-stranded ribonucleic acid in viruses of Penicillium citrinum.

The nucleic acid content of two viral populations in a strain of Penicillium citrinum is shown to be double-stranded ribonucleic acid, resolved through polyacrylamide gel electrophoresis into 10 size groups ranging from 1.17 to 3.98 megadaltons.

Caracterização das adaptações em métodos de avaliação para aplicações colaborativas

Although the development and use of collaborative systems has increased lately, evaluate them is not a simple task. Most of the HCI evaluation methods that are consolidated are aimed at single-user systems and require adaptation in order to be applied to collaborative systems. The goal of this paper is to present an initial characterization of the adaptations that have been proposed in order to...

Bioleaching of Low Grade Manganese Ore with Penicillium citrinum

A native microorganism, Penicillium citrinum was isolated from the top soil of a manganese mine. Based on its efficiency for manganese solubilisation, it was utilized for the leaching of a low-grade manganese ore. The effects of various parameters such as pulp density, particle size, sucrose concentration, inoculum size and bioleaching duration on manganese ore were studied. The optimised condi...
