1. Avaliação e adequação da lavagem no beneficiamento da batata / Assessment and adequacy of washing in the potato processing
The washing for potatoes in São Paulo, for the fresh market or industry, consumes excessive amounts of water, causing damage to the environment mainly due to waste water discharge from the washing step. Considering the requirement of the consumer market for washed potatoes, and the need to reduce water consumption, the hypothesis is that it is possible to r

2. Efeitos citotoxicos e genotoxicos no meristema radicular de Allium cepa exposta a agua do Rio Paraiba do Sul - estado de São Paulo - regiões de Tremembe e Aparecida / Citotoxic and genotoxic effects in the root meristem of Allium cepa exposed to the water of the Paraiba do Sul river - São Paulo state - regions of Tremembe and Aparecida
One of the main sources of pollution of fresh water ecosystems refers to the discharge of industrial and urban wastes. Untreated sewage is considered an important cause to the deterioration of water quality in developing countries. Environmental pollutants have caused a decrease in water quality, inducing harmful effects in organisms which are in direct or i

3. CaracterizaÃÃo das Ãguas e efluentes em lavanderias de jeans no agreste pernambucano
The Productive Local Arrangement (PLA) of confections of Pernambuco is located in a region of water limitations, produced around 15 % of the pieces of jeans of the country, where it is also are carried out the activity of washing and dyeing. The demand for water is around 50 to 300 thousand liters month, caught in the Capibaribe river, the unique source of w

4. Procedimento alternativo para totalização volumetrica indireta de agua bruta
The necessity of crude water and sewer flow discharge measuring is an actual preoccupation because the market is not yet properly adapted for this function. In Brazil most of flow meters and measuring techniques used are specified to be used with fresh water, instead of crude water withdrawals. The objective of this thesis is the supplying of a crude water m

5. Characteristics of hydrography, circulation and salt transport:Cananéia Bar, south of Cananéia Sea and Trapandé Bay. / Características da hidrografia, circulação e transporte de sal: Barra de Cananéia, Sul do Mar de Cananéia e Baía do Trapandé
Este trabalho tem como objetivos estudar a variabilidade das propriedades hidrográficas e da circulação durante ciclos completos de maré, classificar o sistema estuarino com o diagrama estratificação-circulação de Hansen &Rattray, calcular o transporte resultante de sal e a contribuição relativa dos termos advectivos, de difusão turbulenta e a par

6. Sunlight Inactivation of Fecal Indicator Bacteria and Bacteriophages from Waste Stabilization Pond Effluent in Fresh and Saline Waters
Sunlight inactivation in fresh (river) water of fecal coliforms, enterococci, Escherichia coli, somatic coliphages, and F-RNA phages from waste stabilization pond (WSP) effluent was compared. Ten experiments were conducted outdoors in 300-liter chambers, held at 14°C (mean river water temperature). Sunlight inactivation (kS) rates, as a function of cumulati

7. Contrasting Patterns of Phytoplankton Community Pigment Composition in Two Salt Marsh Estuaries in Southeastern United States
Phytoplankton community pigment composition and water quality were measured seasonally along salinity gradients in two minimally urbanized salt marsh estuaries in South Carolina in order to examine their spatial and temporal distributions. The North Inlet estuary has a relatively small watershed with minimal fresh water input, while the Ashepoo, Combahee, an

8. Increase in basal firing rate and sensitivity to angiotensin II in subfornical organ neurones of ducks adapted to salt water.
1. The influence of salt adaptation on spontaneous firing rate of subfornical organ (SFO) neurones and on their responsiveness to angiotensin II (AngII) (10(-10)-10(-7) M) were studied in vitro on hypothalamic brain slices taken alternately from ducks kept on either fresh water (FW ducks) or saline of 500 mosmol/kg for 8 weeks (SW ducks) as their only water
