Eugenol em juvenis de tilápia do nilo: concentrações e administrações sucessivas

Several anesthetics are used in aquaculture to reduce the stress caused by management. In the field, the most common anesthetic is benzocaine, but several authors are researching about eugenol. The objective of this study were to compare the action of these drugs on the anesthetics stages and measure the effects of successive administration of eugenol on the anesthetics stages in Oreochromis niloticus. In the first test, fish (47.73 +/- 8.73 g and 14.23 +/- 0.81 cm) were subjected to five concentrations of eugenol (40, 60, 80, 100 and 120 mg L-1) and one of benzocaine (100 mg L-1). All the anesthetic concentrations tested were able to induce fish to all stages of anesthesia, and revealed an inverse relationship between the induction times and increased concentrations. The minimum concentration of eugenol to induce anesthesia was 100 mg L-1. In the second test, the juveniles (38.07 +/- 5.00 g and 12.70 +/- 0.54 cm) were exposed to concentrations of 60, 80, 100 mg L-1 of eugenol, as determined in the first test. Evaluating the differences between successive days, there was no significant difference (P > 0.05) between anesthetics stages in the concentrations of eugenol tested, suggesting that the residue of eugenol was removed from the fish in less than 24 hours.

Características regionais sobre a ultra-estrutura das células principais do epitélio do ducto epididimal de Agouti paca

The principal (P) cells of epididymidis surface epithelium of Agouti paca were related to processes of adsorptive endocvtosis and phase-fluid endocvtosis, as well as protein secretion apparently also occur. These findings had been proposed on the base the cytoplasmic ultrastructural features of P cells in which were seen an expressive number of vesicles with several shapes, sizes and internalized content occurring also smaller pits and pale small vesicles located next to the apical brush border of microvilli. Moreover, occurred coated vesicles, smooth surface vesicles and great vesicles; multivesicular bodies, endosomes and lysosomes mainly viewed on supranuclear and apical positions. Presence of an appocrine secretory pathway was characterized in P cells through the occurrence of apical cytoplasmic expansions, protruding into the ducts epididymidis lumina) compartment.

Densidades do sistema financeiro: uso corporativo e desigualdades regionais do território brasileiro

Diante da histórica situação geográfica de desigualdade regional brasileira, procuramos destacar a questão da desigual distribuição do dinheiro, analisando tanto a instalação dos fixos bem como a dinâmica dos fluxos do sistema financeiro em território nacional. Demonstramos a territorialização do sistema financeiro, por meio de suas agências bancárias, que controlam hoje a dinâmica dos fluxos monetários no território brasileiro. Contudo, apenas o conhecimento dessas formas geográficas, sua quantificação e topologia de nada nos adiantariam se não investigássemos os fluxos de crédito e de depósitos, revelando as desigualdades resultantes do uso corporativo do território brasileiro. Por último, levantamos dados e realizamos revisão bibliográfica que demonstra a consolidação da cidade de São Paulo como centro financeiro do território nacional.

Marcos estratigraficos regionais na Formacao Palermo: caracterizacao dos picos radioativos

During a basinal scale study on Palermo Formation (Upper Permian, Parana Basin) high elevated Gamma Ray picks were identified mainly in the lower third of that stratigraphic unit. Those Gamma Ray signatures have been used as good regional stratigraphic markers. From them it was possible one chronostratigraphic analysis of Palermo Formation as pointed out by previous papers (Perinotto). Potassium40 is the responsible for the high Gamma Ray picks in the Palermo Formation. -from English summary

Diferenças regionais do cultivo de café no Brasil

Brazil is one of the major coffee producers in the world, because of this, the goal of this study was to assess the regional differences of coffee cultivation for the reference crops 2001/2002 and 2002/03 by means of a life cycle assessment (LCA) in order to generate detailed production inventory data as well as quantify the potential environmental impacts of this crop. All information considered in this study (use of water, fossil based energy, fertilizers, pesticides and correctives) was taken from data collected from the producing farms. Four Brazilian coffee producer regions located at the Southeastern region were evaluated: Sul de Minas Gerais and Cerrado Mineiro in Minas Gerais State, and Mogiana and Alta Paulista regions in São Paulo State. The data refer to a production of 25.2 million kg of green coffee. Depending on the considered region, the production of 1,000 kg of green coffee requires, on average, approx. 9,300 to 13,000 kg of total energy, 70 to 130 kg of diesel, 6,500 to 12,700 kg of process water, 270 to 340 kg of fertilizers (NPK), 2.0 to 13.0 kg of pesticides, 230 to 600 kg of correctives, and yield around 1,600 to 1,900 kg/ha. Despite 20% of the coffee growers showing a good environmental performance, i.e. consumption of pesticides, fertilizers and correctives lower than the regional averages, this study has also identified some farms that can probably reduce the amount of some inputs and enhance their environmental performance.
