This work evaluated the rainwater chemical composition and the annual atmospheric deposition in Sorocaba, (Sao Paulo State), Brazil. One sampling ˜ point was chosen and forty samples were collected between January and December 2006. The analyses were performed for pH, electrical conductivity, sodium, calcium, potassium, magnesium, sulphate, nitrate, phosphate, alkalinity and chloride. The rainwater pH varied from 5.20 to 6.40, being Ca2+ the main ion responsible for controlling the rainwater pH. The ionic concentration decreases in the following order: Ca2+>Na+> K+>Mg2+ for cations and SO2− 4 >HCO− 3 >NO− 3 >Cl−>PO3− 4 for anions. The annual atmospheric deposition appears to be controlled by the following sources: mining activities and cement factories (Ca2+ and HCO− 3 ), agricultural activities (K+, NO− 3 and PO3− 4 ), soil dust (Na+, Mg2+ and HCO− 3 ) and fossil fuel burning (SO2− 4 )

A presente invenção descreve um selante de fibrina, o qual compreende uma serinoprotease extraída a partir de veneno de serpente, um crioprecipitado rico em fibrinogênio extraído de bubalinos e o diluente cloreto de cálcio. A invenção ainda ensina o método de formação do selante, cujos componentes são providos separadamente e polimerizam-se in situ após mistura, bem como seu uso. O selante de fibrina descrito apresenta inúmeras aplicações médicas tópicas e não há o risco de transmitir doenças infecciosas.

Tratamentos com retardantes de crescimento vegetal foram estudados em plantas de Palma de Santa Rita (Gladiolus communis L. spp., Iridaceae) para avaliar a altura da planta, o número de folhas e botões florais, diâmetro do caule e comprimento da haste floral. O delineamento experimental utilizado foi inteiramente casualizado, com quatro repetições e sete tratamentos (testemunha; aplicações de cloreto de mepiquat na concentração de 200mg.L-1, 3 e 6 vezes; cloreto de chlormequat na concentração de 200mg.L-1, 3 e 6 vezes e ethephon na concentração de 200mg.L-1, 3 e 6 vezes). Foram realizadas sete avaliações não destrutivas a cada sete dias e uma coleta final. Os tratamentos com ethephon proporcionaram redução da altura das plantas e do comprimento.

The effects splenic dilatation induced by acepromazine in a prospective, randomized study. Thirtythree adult mongrel dogs were divided into two groups designated as AG (acepromazine 0.05 mg/kg, i.v., n = 23) and CG (0.9% sodium chloride administered at a similar volume, n = 10). In both groups underwent sonographic examinations before (T0) and fifteen minutes (T15) after drug injection. The thickness spleen and splenic vein width were measured. Higher thickness was found in the AG group at T15 (2.47 cm) when compared to that at T0 (2.06 cm, p = 0.016), while the T0 (2.33 cm) and T15 (2.39 cm) measures did not differ within the CG group. Moreover, the splenic vein width was higher (p = 0.013) at T15 than at T0 in the AG group. Based on results of this study, we concluded that acepromazine, in doses of 0.05 mg/kg, promotes splenomegaly in dogs after fifteen minutes of the injection.

Brazil is a major importer in the world salted fish trade. The sale of these products must meet the established standards, based mainly on the salt and moisture levels. The aim of this study was to analyze the salt and moisture levels in imported Atlantic cod and Pacific cod, and in the dried salted fish Ling, Zarbo and Saithe, which are not classified as cod since they do not belong to the genus Gadus. The water activity was also analyzed, which could be a useful parameter to determine the quality of salted fish.The results showed that the legal limits for salt were much lower than the values found in the analyses. The moisture contents established for the category of salted fish, as determined by the Portuguese legislation, were more reliable. We suggest the inclusion of the water activity as a parameter for the evaluation of these products.
