ABSTRACT

Due to the concern with the quality of hydric resources, the monitoring is essential to evaluate and identify the anthropogenic and environmental interferences in a quantitative and qualitative level. In order to assist the interpretation of the water status of hydric bodies, the gathering of analytical data often considers the Water Quality Index (WQI). This index transforms technical information in description of the water quality status, highlighting the effectiveness of its use and guiding the decision-making process when necessary. The aim of this research is to assess the water quality of a region in São Paulo State, Brazil, by means of the WQI of Jaguari and Atibaia Rivers. The period of intense drought, which affected the Brazilian southeast in 2014, was evaluated and compared to the mean values recorded from October 2009 to March 2015, correlating the values of Escherichia coli and the biochemical oxygen demand (BOD). One hundred nine samples were collected, being 53 from dry seasons, between October and March, and 56 from rainy seasons, between April and September. The WQIs in Jaguari and Atibaia Rivers, during dry season, were of 42.2 (medium) and 36.7 (bad), respectively. The same pattern was registered for the dry season, for both rivers, with indices values of 40.1 for Jaguari River (medium) and 34.9 for Atibaia River (bad). This research presented the need of an effective evaluation of the environmental quality and preservation by competent organs for both rivers. Due to the detected conditions, special attention should be given to the Atibaia River.

ABSTRACT

Este estudo visou verificar o efeito da fonoforese com Arnica montana sobre a fase inflamatoria aguda de uma lesão muscular. Para isso, 40 ratos Wistar machos, lesados cirurgicamente, foram divididos em 4 grupos: controle (C), 10 ratos lesados e não tratados grupo ultra-som (US), 10 lesados tratados com fonoforese de gel de arnica; grupo arnica (A), 10 ratos lesados, tratados com massagem de gel de arnica...


This study aimed at verifying the effects of phonophoresis associated to Arnica montana on the acute phase of an inflammatory muscle injury. Forty Wistar male rats of which the Tibialis. Anterior muscle was surgically lesioned, were divided into 4 groups (n+10 each); control group received no treatment the ultrasound group (US), treat with US; the US+A group was treat with arnica phonophoresis...

ABSTRACT

O presente trabalho apresenta os resultados dos tratamentos eletrolíticos (05; 15; 30; 45 e 60 min) no efluente simulado com o composto Flexzone 3P, utilizando-se eletrodos de Ti/TiRuO2, sob 0,025 A cm-2. Após as eletrólises, foram feitas análises de pH, condutividade, espectrofotometria no UV-vis, análise por cromatografia gasosa, ensaios de toxicidade utilizando Saccharomyces cerevisiae e ensaio de respirometria de Bartha. O pH dos efluentes foi diminuindo à medida que aumentou- se o tempo de eletrólise, ao contrário da condutividade, a qual apresentou pequeno aumento. Verificou-se que após 60 min de tratamento foi obtida diminuição da concentração do composto Flexzone 3P em 65,1%. Analisando-se os espectros de UV-vis e cromatogramas do efluente após realização do tratamento eletrolítico, concluiu-se que ocorreram oxidações e transformações de funções orgânicas do composto, durante os tratamentos. Após a realização do tratamento eletrolítico, o efluente simulado apresentou diminuição da toxicidade a S. cerevisiae, após 5 min de eletrólise. O tempo de eletrólise de 5 min foi o que apresentou melhor resultado de biodegradação do que os demais períodos de tratamento, no ensaio de respirometria para o efluente com o composto Flexzone 3P.
