A survey of surface, spring and borehole waters associated with the ophiolite rocks of Cyprus shows five broad water types (1) Mg-HCO3, (2) Na-SO4-Cl-HCO3, (3) Na-Ca-Cl-SO4-OH-CO3, (4) Na-Cl-SO4 and (5) Ca-SO4. The waters represent a progression in chemical reactivity from surface waters that evolve within a groundwater setting due to hydrolysis of the basic/ultrabasic rock as modified by CO2-w...

Aerosols samples of PM2.5 were collected during October 2004 in the industrial zone of the greater Athens area, located in the coastal region of Saronic Gulf, westerly of the city. In particular, two different sites were selected, in order to obtain experimental data from: a) the shoreline, where industrial activity and vehicular traffic were intense, and b) the mainland, where residential acti...

The hydrochemical and isotopic techniques have become one of the most popular successful methods for determining hydrogeochemical features groundwater in recent years. A total 15 samples were collected during wet (March, 2021) dry (August, seasons. An approach with major elements (Cl-, Na+, Mg2+, Ca2+, SO4 2=) multi-isotope (2H, 18O) are used this study to solve geochemical variation salinity B...

A detailed analysis of the magnetic properties a vanthoffite type mineral Na6Mn(SO4)4 basedon dc magnetization, low temperature neutron powder diffraction and theoretical calculations is reported. The crystallizes in monoclinic system with space group P21/c, where MnO6 octahedra are linked via SO4 tetrahedra. This gives rise to super-exchange interaction between two Mn2+ ions mediated by nonmag...

Anorthominasragrite, V4+ O (SO4) (H2O)5, is a new mineral species from Temple Mountain, Emery County, Utah, U.S.A. It occurs as blue-green crusts and spherical granular aggregates (up to ~1 mm across) in a fossil (Triassic) tree; individual crystals are <0.1 mm and are intimately intergrown. Anorthominasragrite has a white streak, a vitreous luster, and no observable fluorescence under ultravio...

In the present work, polyvinylidene fluoride's (PVDF) electrical and optical properties have been studied as a function of cerium sulfate tetrahydrate called Ce(SO4)2. Experimental result shows that relative percentage β phase (Fβ%) increases by almost 55 % with Ce(SO4)2 addition in polymeric matrix. The dielectric permittivity measurements presented an increase, at 1 KHz, 62% up to 0.8% conten...

The effects of various intracellular anions on the G protein (GK)-mediated activation of the muscarinic K+ (KACh) channel were examined in single atrial myocytes isolated from guinea pig hearts. The patch clamp technique was used in the inside-out patch configuration. With acetylcholine (ACh, 0.5 microM) in the pipette, 1 microM GTP caused different magnitudes of KACh channel activation in inte...

Sulfate reduction rates (SRR) and concentrations of SO4 , H2S, pyrite sulfur, total sulfur, CH4, and organic carbon were measured with high depth resolution through the entire length of the SO4 -zone and well into the CH4-zone at two continental slope stations in the eastern South Atlantic (Benguela upwelling area). The sediments were characterized by a high organic carbon content of approx. 7....

Soils overlying two porphyry Cu deposits (Spence, Gaby Sur) and the Pampa del Tamarugal, Atacama Desert, Northern Chile were collected in order to investigate the extent to which saline groundwaters influence ‘‘soil’’ chemistry in regions with thick Miocene and younger sediment cover. Soil carbonate (calcite) was analyzed for C and O isotopes and pedogenic gypsum for S isotopes. Soil calcite is...
