Environmental aspects and the decapod fauna of several estuaries and coastal lagoons in the southwestern Atlantic, between 25 and 41°S, are compared: Baia de Paranaguá, Manguezal de Itacorubí, Lagoa dos Patos (Brasil), Laguna Castillos (Uruguay), Río de la Plata (Uruguay-Argentina), Laguna Mar Chiquita and Bahía Blanca (Argentina). The information about natural history of crab species (Crustace...

Methods Consecutive case control pilot study, with radiological results in coronal and sagittal curves, and scores for overall-satisfaction with TLI after one year of wearing. 91 consecutive children with scoliotic ( one curve >25o) and kyphotic spinal deformities during growth, wearing a lordotic brace at least a full year. Measurements of Cobb angles on AP and sagittal standing X-ray’s were c...

The protonation constants of alanine and alanine methyl ester were determined in different aqueous solutions of 1,4-dioxane containing (0-50% v/v), using a potentiometric method at 25o C and constant ionic strength 0.1 mol.L-1 (NaCl). The protonation constants were analyzed in terms of Kamlet, Abboud and Taft (KAT) parameters. The results show that the effect of β is higher in comparison with t...

This study addresses the impact of satellite altimetry data processing on sea level studies at regional scale, with emphasis on the influence of various geophysical corrections and satellite orbit on the structure of the derived interannual signal and sea level trend. The work focuses on the analysis of TOPEX data for a period of over twelve years, for three regions in the North Atlantic: Tropi...

Wheat germ represents approximately 3% of the grain and it contains 8-14% oil, which is a rich source of tocopherols (vitamin E) and polyunsaturated fatty acids, mainly linoleic acid. The present work shows the influence of temperature (27oC and 45oC) and storage time (maximum 35 days) of the wheat germ on the concentration of tocopherol in the oil. Their effect on other quality parameters was ...

Algae are sustainable sources of biomass for fuel, food, feed and essential for their growth are light, CO2, and inorganic nutrients like nitrogen and phosphorous. The aim of our study was to explore the effect of different carbon sources on biomass accumulation in microalgae Chlorella vulgaris and its ability to remove N and P compounds during its cultivation in aquaculture wastewater. Microal...

To increase catfish productivity, the Directorate General of Aquaculture continues to innovate and develop technology that results in a more efficient enlargement system. The purpose this study is find out most economically feasible sangkuriang system between biofloc conventional systems. From water quality measurements temperatures 25-27oC, pH 7, DO 1.2 – 2.2, FCR 0.9 1.1 are still good range....

Goalpara district covering an area of 1,824sq.km.in the western part south bank Brahmaputra in Assam extends between 25o 54/N to 26o 17/N latitude and 90o3/E 91o6/E longitude. The along with its surrounding areas basically central parts are very suitable for cultivation banana one important fruit crop district. is not only rich production but also it has some big collecting centers mainly at Da...

The effects of thermospheric winds and electric fields on the ionospheric FZlayer are controlled by the geometry of the magnetic field, and so vary with latitude and longitude. We adopt a simple model of the daytime F2-layer and study the effects at midlatitudes (25O-65” geographic) of three processes that accompany geomagnetic storms : (i) thermospheric changes due to aurora1 heating; (ii) equ...
