This paper investigated the effects of seawater curing of concrete made by Micro-Nano Air Bubbles (MNAB) on compressive, flexural and tensile strengths of the concrete. This product will be applicable for rehabilitation or repair of coastal RC structures. In this research, the effect of different combinations of concrete ingredients including 0-100, 25-75, 50-50, 75-25, and 100-0 percent ...

Objective(s):Protective effects of diuretics, particularly of hydrochlorothiazide (HCT), for the development of seizure attacksepilepsy have been described in vivo. However, itsthe mechanism of action of HCT is unknownneeds to be elucidated. Materials and Methods: Extracellular field potentials were recorded from the CA1- and CA3-subfields of the hippocampus of rats. Epileptiform discharges wer...

We report the first direct measurements of the contribution of phytoplankton and bacterial cells to the measured alkalinity of unfiltered seawater. Phytoplankton and bacterial cells suspended in seawater make a significant contribution to the measured alkalinity of unfiltered seawater; their contribution is probably next to that of borate ion in most seawater samples. This nonnegligible contrib...

Several investigations have recently considered the possible impacts of climate change and seawater level rise on seawater intrusion in coastal aquifers. All have revealed the severity of the problem and the significance of the landward movement of the dispersion zone under the condition of seawater level rise. Most of the studies did not consider the possible effects of the seawater rise on th...

The hippocampus plays an important role in the genesis of mesial temporal lobe epilepsy, and the entorhinal cortex (EC) may affect the hippocampal network activity because of the heavy interconnection between them. However, the mechanism by which the EC affects the discharge patterns and the transmission mode of epileptiform discharges within the hippocampus needs further study. Here, multielec...

Luminous bacteria in seawater around the islands of Bahrain are predominantly Vibrio harveyi and have the capability to adhere to artificial fibrous surfaces. Phytoplankton did not appear to have any specific relationship with luminous bacteria, but macroalgae were shown to possess an enhanced concentration of luminous bacteria.

Abstract The study presents monthly variations of seawater properties, monitoring water column stability and stratification over the southern shelf of the Caspian Sea which depends on collecting data. Field measurements were carried out during 13 cruises along the southern boundary of the sea. Spatial and temporal distributions of temperature, salinity and density were investigated. Monthl...
