1. Electrical conductivity in different structure of bean seeds / Condutividade elétrica em diferentes estruturas de sementes de feijão
Uma das principais exigências para a avaliação do vigor de sementes refere-se à obtenção de resultados confiáveis em um período de tempo relativamente curto, permitindo a agilização das tomadas de decisões. O objetivo deste trabalho foi avaliar a eficiência do teste de condutividade elétrica, conduzido com diferentes estruturas de sementes de fe

2. SEPARAÇÃO E PRÉ-CONCENTRAÇÃO ON-LINE PARA ESPECIAÇÃO DE Hg EM CHORUME POR FI-CVG AAS
In Brazil, the urban solid wastes are usually discharged on landfill sites that are percolated by rainwater. This water leaches the wastes producing an effluent that is characterized by high concentration of organic matter, salts, suspended particulates and heavy metals. Mercury is one of the metals that is frequently present in different chemical forms whic

3. Alquilguanidinas imobilizadas em matrizes inorganicas
The preparation of novel base catalysts by the immobilisation of alkylguanidines in hydrophobic zeolite Y, hexagonal mesoporous silica MCM-41 and SiO2 sol-gel matrixes was studied. The encapsulated alkylguanidines were prepared by the reaction of primary amines with dicyclohexylcarbodiimide previously diffused into the zeolite. The anchoring of alkylguanidin

4. Cyclohexanone contamination from extracorporeal circuits impairs cardiovascular function
Extracorporeal circulation provides critical life support in the face of cardiopulmonary or renal failure, but it also introduces a host of unique morbidities characterized by edema formation, cardiac insufficiency, autonomic dysfunction, and altered vasomotor function. We tested the hypothesis that cyclohexanone (CHX), a solvent used in production of extrac

5. An Intracellular Iron Chelator Pleiotropically Suppresses Enzymatic and Growth Defects of Superoxide Dismutase-Deficient Escherichia coli
Mutants of Escherichia coli that lack cytoplasmic superoxide dismutase (SOD) exhibit auxotrophies for sulfur-containing, branched-chain, and aromatic amino acids and cannot catabolize nonfermentable carbon sources. A secondary-site mutation substantially relieved all of these growth defects. The requirement for fermentable carbon and the branched-chain auxot
