| The analysis of geology and structure of the study area (East Nile - North Khartoum) is attempted by utilizing regional gravity and vertical electrical sounding (VES) data to investigate the source of the high gravity encountered over the basin features in this area as well as to reveal the structures, sedimentary sequences and groundwater condition in the area. The regional gravity measurements are achieved along two profiles in the area using Scintrex CG-3 gravimeter. All corrections common in gravity method are applied to the field data to produce Bouguer anomalies. The Bouguer anomalies are combined together with those produced by Sun Oil Company in 1984 and the residual anomaly separation is made using the least-squares method. The residual anomalies... |

| Durante los meses del verano austral (Nov. 1997-feb.1998) se realizó la VII Expedición Ecuatoriana a la Antártida a bordo del B/I ORION del Instituto Oceanográfico de la Armada. del 24 al 27 de enero/98, se realizaron 14 estaciones oceanográficas en el interior del Estrecho Bransfield donde además de varios parámetros físicos, meteorológicos y biológicos se estudiaron parámetros químicos como micronutrientes y oxígeno disuelto hasta una profundidad de 500 m. Se exponen los criterios y resultados obtenido de la distribución superficial y subsuperficial de los nutrientes y oxígeno disueltos. Se describen los diagramas T/S de las masas de aguas identificadas y su composición química. Las aguas superficiales del interior del Estrecho Bransfield se presentaron... |

| The aim of this study was to investigate the relationship between the concentrations of heavy metals in well water and bioaccumulation of the most abundant metals in chicken tissues in some areas in the province of Mecca Almokaramah, Saudi Arabia. Among the heavy metals (Cd, Zn, Cr, Mn, Cu Hg, Pb and Ni) studied, mercury (Hg) revealed highest in concentration in well waters. The concentration of mercury in the ground water, beside in liver, kidney, muscle and blood samples of ten chickens from each of four poultry- production farms were estimated using atomic absorption spectrophotometer. The results showed that the kidney followed by liver had the highest bioaccumulation of mercury in all farm samples. The level of mercury in the ground water was... |
