Spatial and temporal variations of mercury (Hg) concentrations were monitored in the surface waters from lower portion Tapajós River, Arapiuns its principal tributary, Amazon River at confluence with Tapajós. In rivers, Hg water column are governed by concentration suspended particles. filtered showed very little seasonal variation low (<1.8 ng L −1 ), (<0.8 (<2.8 ). Concentrations fine particulate (0.6–29.7 ) represent 40%–90% total volumetric Hg. relation to their oxyhydroxide...
This study was designed to evaluate the effect of different conditions collection, transport and storage on quality blood samples from normal individuals in terms activity enzymes ß-glucuronidase, total hexosaminidase, hexosaminidase A, arylsulfatase A ß-galactosidase. The enzyme activities were not affected by materials used for collection (plastic syringes or vacuum glass tubes). In evaluation heparin concentrations (10% heparin, 5% heparinized syringe) syringes, it observed that higher...
A crescente complexidade do mundo contemporâneo, impulsionada por avanços tecnológicos e mudanças socioculturais, demandam habilidades matemáticas substancialmente diferentes das necessárias em épocas passadas. adoção de jogos como uma metodologia alternativa a inserção materiais concretos atividades educacionais, auxiliam na construção produção conhecimentos necessários nesse cenário. Visando aproveitar esses instrumentos, propôs-se um projeto extensão/pesquisa com três objetivos –...
