Cádmio, chumbo, cromo, mercúrio e níquel nos rios do estado de São Paulo e em peixes do Rio Sorocaba (São Paulo, Brasil)

To verify the levels of concentration of some heavy metals in fishes from Sorocaba river (São Paulo, Brazil) and evaluate if this contamination offers health risks to the fishermen, 63 samples of fishes collected from four points along the river were studied for cadmium, lead, chromium, nickel and mercury, with emphasis in this last, since it is the most toxic and most probable as a fish contaminant. Analyzing muscle samples by cold vapor atomic absorption spectrometry it was shown that the fishes are not contaminated. None of the five metals studied were present in prohibitive level and the fishes could be judged secure for human consume. It was also analyzed data from four years of cadmium, lead, chromium, nickel and mercury monitoring made by CETESB, from 1997 to 2000, in water from the main rivers of the State of São Paulo. The study pointed out that the majority of the monitored rivers still present contamination by those metals in a level that requires an improvement of the pollution control actions.

Políticas públicas municipais de apoio a atividades econômicas em assentamentos rurais: uma análise em quatro municípios paulistas

This paper reports a master research that aimed to analyze the patterns of institutional relationships between local officials and communities of agrarian reform settlements in four counties of the State of São Paulo – Apiaí, Iaras, Promissão and Mirante do Paranapanema – particularly with regard to the types of support offered by the first to the economic activities in the settlements. In terms of methodology, we conducted a qualitative, exploratory and descriptive research, outlined in the format of multiple case study. Having like data sources the local officials responsible for institutional relations with the agrarian reform settlements, technicians agents of agencys linkeds to the land question, as INCRA and ITESP, and settled in leadership positions in rural settlements, we sought to evaluate the intensity, the types and quality of the (possible or actual) support offered by municipalities to economic activities inside the settlements. We sought to evaluate the results from theoretical lens formed around the notions of local development and the significance assumed by settlements in different locations. The results showed a fairly heterogeneous and, often, disparate in particular circumstances. It was evident, from the information collected, that a positive action of the municipal government in supporting the economic activities of the settlements is essential for the release of social energy based in settlements, enabling the realization of the "amalgam of possibilities" constructed from the implementation of rural settlements.

Resina composta indireta como alternativa funcional e estética em reabilitações protéticas

Due to mechanical and aesthetic improvement properties, continuous fiber-reinforced composites have been developed to replace the metal framework in fixed partial dentures becoming an interesting alternative to conventional treatments. A male patient, 57 years old, attended at Fixed Partial Denture Clinic of Araraquara Dental School - UNESP, complaining about upper right first molar absence. After clinical examination, it was observed: upper right second molar with amalgam restoration and periodontal bone reduction and upper right second premolar unsatisfactory treated. Following the clinical conditions and the patient expectations, it was decided to use a fiber-reinforced composite resin to make a three-element fixed bridge. The patient showed full satisfaction with the aesthetic and functional results. The case has been followed up for 60 months.
