A qualidade da água em áreas rurais é de difícil conhecimento, uma vez que a distribuição não ocorre igualmente em todos os lugares, o que implica na dificuldade das análises individuais. Dessa forma, a água para consumo humano de dezoito lotes rurais em Ilha Solteira foi avaliada em relação a alguns parâmetros físicos e químicos e, em especialment...
O conhecimento a respeito das caracteristicas da agua ofertada aos animais domesticos em areas rurais torna-se dificil, uma vez que geralmente os produtores rurais tem pouco conhecimento sobre a importância da qualidade da agua destinada aos mesmos, o que, alem de os deixarem susceptiveis a doencas de veiculacao hidrica, representa mais uma ameaca...
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...
The bioconcentration of cadmium and lead by the freshwater crab Trichodactylusfluviatilis was evaluated. Thirty animals were exposed to 200 µg L-1 of cadmium and lead for 7, 14 and 21 days. Both metals were determined in gills, hepatopancreas and muscle after dissection and digestion by inductively coupled plasma optical emission spectrometry. Lead...
Determinations of Al and Mn concentrations in the tissues (gills, hepatopancreas and muscle) of the freshwater crab Trichodactylus fluviatilis and water samples, both collected from sites on tributaries of the Corumbataí River (São Paulo, Brazil) were performed. The Bioaccumulation Factor (BAF), calculated for different sites with respect to the wa...
To study the effect of an 830-nm gallium-aluminum-arsenic (GaAlAs) diode laser at two different energy densities (5 and 15 J/cm(2)) on the epiphyseal cartilage of rats by evaluating bone length and the number of chondrocytes and thickness of each zone of the epiphyseal cartilage.
Few studies have been conducted on the effects of low-level laser the...
A toxicidade para a minhoca Eisenia fetida de amostras de solo de landfarming de refinaria de petróleo foi avaliada em solo inoculado com comunidades de algas alóctones isoladas de solo limpo. Amostras do solo de landfarming da Refinaria de Petróleo de Paulínia (REPLAN/PETROBRAS) foram mantidas sob saturação hídrica em bandejas plásticas, em Casa d...
Cyclodextrin glycosyltransferase (CGTase) activity was produced by the Bacillus sp., subgroup alcalophilus in a culture medium containing cassava starch. A central composite design and response surface methodology were used to study the influence of carbon source (cassava starch), nitrogen sources (yeast extract and tryptone) and sodium carbonate i...
Neste trabalho foram discutidos aspectos conceituais e práticos (mediante exemplo hipotético com Lycopersicum esculentum) que devem ser levados em consideração na utilização do teste de Kruskal-Wallis (teste estatístico não-paramétrico), enfatizando-se as complicações que podem surgir se esse procedimento estatístico for implementado de maneira arb...
Landfarming is a bioremediation technique to remediate soils contamined for residual treatment from petrochemical industry. In this study, Eisenia fetida was used to verify the landfarming soil detoxication from petrochemical sludges by allochthonous algal community. Soil samples were collected at 0-20 cm in landfarming Paulínia oil refinery (REPLA...
Determinations of Al and Mn concentrations in the tissues (gills, hepatopancreas and muscle) of the freshwater crab Trichodactylus fluviatilis and water samples, both collected from sites on tributaries of the Corumbataí River (São Paulo, Brazil) were performed. The Bioaccumulation Factor (BAF), calculated for different sites with respect to the wa...
This study aimed at verifying the effects of phonophoresis associated with Arnica montana on the acute phase of an inflammatory muscle lesion. Forty Wistar male rats (300+/-50 g), of which the Tibialis Anterior muscle was surgically lesioned, were divided into four groups (n=10 each): control group received no treatment; the ultrasound group (US) w...
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), treated with US; th...
RESUMO O Índice de Depuração do baixo curso do Rio Corumbataí, SP, foi avaliado considerando a importância da água, quanto à qualidade e quantidade para abastecimento público através do índice K2. Sazonalmente nos períodos úmido/quente e seco/frio foram realizadas coletas em dois afluentes do Rio Corumbataí, o Rio Passa-Cinco e o Ribeirão Água Verm...
This study investigated the effects of electrolytic treatment using Dimensionally Stable Anode (DSA, 70%TiO2/30%RuO2) type electrodes in simulated wastewater containing aromatic amine n-phenyl-n'-1,3-dimethylbutyl-p-phenylenediamine (Flexzone 7P). A low direct current density of 0.025 A cm(-2) was applied for periods up to 60 minutes and a 52.6% de...
Neste artigo, são descritos conceitos de Web 2.0 e de e-Governo, destacando as suas afinidades e também as possíveis aplicações para a aproximação do Estado com os cidadãos nos processos decisórios entre os mesmos. Defende-se a utilização do paradigma Web 2.0 como facilitador do e-Governo, focando nas aplicações para definição de políticas de Segur...
The depuration rate of the low stretch of the Corumbataí River, SP, was evaluated by using the K2 index, considering the importance of the quality and quantity of the water as a vital source of drinking water. Water samples were taken in the humid/hot and dry/cold seasons in the Corumbataí River and two tributaries, the Passa-Cinco River and the Ri...
The quantity and distribution of vegetal biomass are important aspects to consider in ecosystem studies. However, little information is available about Brazil's Pantanal woodland savannas. This work involved the development of regression equations of the aerial biomass and wood volume of native tree species in a region of woodland savanna on Rio Ne...
This study investigated the effects of the electrolytic treatment in the simulated wastewater with aromatic amine n-phenyl-n-isopropyl-p-phenylenediamine (Flexzone 3P®) using Ti/TiRuO2 electrodes under 0.025 A/cm2 (DC) for different electrolysis durations (5; 15; 30; 45 and 60 min). Conductivity, pH, UV-visible spectra, gas chromatograms, toxicity...
RESUMO A fim de analisar a viabilidade celular de Saccharomyces cerevisiae e Candida albicans mantidas em suspensão aquosa acondicionada em frascos de vidro e garrafas de politereftalato de etileno – PET – incolores e verdes expostas à radiação solar direta, utilizaram-se células das leveduras para contaminar água de abastecimento público após neut...
