By means of a series of borehole resistivity measurements and a resistivity±salinity relation, a particular salt-freshwater inversion was found under the shore with semi-diurnal tides at the French±Belgian border. These resistivity data provide valuable information about the vertical variation of the saltwater percentage in di€erent boreholes. At di€erent places and depths ̄uctuations of freshwa...

Introduction The exposure of human beings to ionizing radiation from natural sources is a continuing and inescapable feature of life on earth. For most individuals, this exposure exceeds that from all man-made sources combined. Materials and Methods In this study, the annual effective dose in high level environmental background radiation areas (HLEBRAs) of northern city of Ramsar in Iran was de...

• Abstract: The tidal circulation in Paranagua Bay (Parana State, Southern Brazil) was studied based on the Princeton Ocean Model. The model domain covered the near shore region and the estuarine area, with about 1 km grid resolution in cross-shore and along-shore directions. Homogeneous and diagnostic distributions for temperature and salinity were used and 12 tidal constituents were considere...

Astrocytic lineage commitment and brain region-dependentspecialization of glia are partly ascribed to epigenetic proc-esses. Clearance of glutamate is an essential task, whichastrocytes assume in a temporal-spatial fashion by distinctglutamate transporter expression. Glutamate transportersubtype 1 (GLT-1) is predominant in cortex (CTX), while itplays an inferior role...

Worldwide growth of offshore renewable energy production will provide marine organisms with new hard substrate for colonization in terms of artificial reefs. The artificial reef effect is important when planning offshore installations since it can create habitat enhancement. Wind power is the most advanced technology within offshore renewable energy sources and there is an urgent need to study ...

Coelenteron contents of anemones Actinia equina collected from 2 shore heights (upper and lower) on 3 shores (exposed, semi-exposed and sheltered) in south-west Ireland were investigated in summer 2009. Diets of exposed and semi-exposed shore anemones were dominated by small mussels Mytilus edulis, mostly (>90%) with broken/cracked shells. The diet of anemones on the sheltered shore was dominat...

Identifying locations for secure sequestration of CO(2) in geological formations is one of our most pressing global scientific problems. Injection into basalt formations provides unique and significant advantages over other potential geological storage options, including large potential storage volumes and permanent fixation of carbon by mineralization. The Central Atlantic Magmatic Province ba...

Variation in growth and habitat use is closely connected to individual responses to habitat specific resource levels and predation risk. In three mountain lakes which differed in the density of young-of-the-year (YOY) arctic char (Sal elinus alpinus), we studied the growth, diets and habitat use of YOY char in relation to resource levels. With two model approaches, we further examined the exten...

The dynamics of wind-driven coastal upwelling and downwelling are studied using a simplified dynamical model. Exact solutions are examined as a function of time and over a family of sloping topographies. Assumptions in the two-dimensional model include a frictionless ocean interior below the surface Ekman layer, and no alongshore dependence of the variables; however, dependence in the cross-sho...
