Um método simples e rápido foi desenvolvido para análise de bifenis policlorados (PBC) em transformadores a óleo. O método baseia-se na extração líquido-líquido em metanol e subseqüente determinação direta por cromatografia gasosa acoplada a espectrômetro de massa. A polaridade do metanol permite extrair PCBs, junto com uma quantidade mínima de componentes apolares do óleo, evitando assim etapa...

Metacognitive deficits are well documented in schizophrenia spectrum disorders as a decreased capacity to adjust confidence performance cognitive task. Because metacognitive ability directly depends on task performance, might be driven by lower among patients. To test this hypothesis, we conducted Bayesian meta-analysis of 42 studies comparing abilities 1425 individuals with compared 1256 match...

The amino acid sequences of 369 human nonolfactory G-protein-coupled receptors (GPCRs) have been aligned at the seven transmembrane domain (TM) and used to extract the nature of 30 critical residues supposed--from the X-ray structure of bovine rhodopsin bound to retinal--to line the TM binding cavity of ground-state receptors. Interestingly, the clustering of human GPCRs from these 30 residues ...

The purpose of this paper is to propose an algorithm for solving the split feasibility problems for total quasi-asymptotically nonexpansive mappings in infinite-dimensional Hilbert spaces. The results presented in the paper not only improve and extend some recent results of Moudafi [Nonlinear Anal. 74:4083-4087, 2011; Inverse Problem 26:055007, 2010], but also improve and extend some recent res...

AIM This study attempts to identify any association between length of exposure to urban environmental risk and non-infectious chronic disease in a group of Australian residents who lived in the same location for at least 20 years. METHODS Using Australian survey data, we selected 1256 participants who were 45 years and older and had lived in the same location for at least 20 years. We used lo...
