An artificial neural network (ANN) model-based approach was developed and applied to estimate values of air temperature and relative humidity in remote mountainous areas. The application site was the mountainous area of the Samaria National Forest canyon (Greece). Seven meteorological stations were...

In our experimental work the opportunities of improving of mechanical properties of rubbers and their composites have been investigated. On the one hand the reuse of milling product of recycled rubbers (recycled crumb rubbers) has been studied and the effects of the filler and compatibilizers...

Electric Arc Furnace Dust (EAFD) generated through the production of carbon and alloy steel products is classified as environmentally hazardous waste mainly because of its relatively high levels of Pb, Cd and Cr. The aim of the present work was to investigate the effect of the EAFD addition on the...

A High Cation Exchange Capacity (HCM) montmorillonite clay has been prepared by acetate treatment of Zenith clay. The HCM has been evaluated for metal-uptake from aqueous solutions. The present data show that the cation exchange sites can play a significant role in the adsorption of metals in...

Activated carbon (AC) amendment for reduction of contaminant exposure in polluted soils and sediments has recently emerged as a promising remediation technique. Here, we provide a short overview of the state-of-the-art in activated carbon (AC) amendment to such sites. Most studies not only in...

The important advantage of zeolite applied to water treatment is its high porosity when comparing to other minerals. The porosity results in good hydrodynamic properties (the increase in the pressure loss on the zeolite filters is 1.5-2.0 times smaller than in the case of sand filters) and...

The dependence of Cd(II) and Cu(II) uptake by yeast cells on the age and temperature of cell culture was studied. Saccharomyces cerevisiae, Kluyveromyces marxianus and Debaromyces Hansenii were chosen as typical yeasts, while Cd(II) and Cu(II) as typical metal pollutants. Our results revealed that...

The mechanism of retention of vanadium oxo-species at the “titanium oxide/aqueous solution” interface was investigated over a wide pH range (4-9) and V(V) solution concentration (10-5-2×10-2 M) by combining equilibrium deposition experiments, potentiometric titrations, microelectrophoresis and...

Through transportation accidents or intentional releases, plastic pellets (small granules 1-5 mm in diameter) are widely distributed in the ocean all over the world. These pellets accumulate organic pollutants and can be used for the determination of diffusive seawater pollution. Pellets...

Halite–crystals produced in solar salts Works of Sfax Saline (E.S of TUNISIA), more often, contain fluid inclusions which fill inter– and intra–crystalline cavities and represent from 3 to 5 % in mass. With the sole aim of quantifying the impact of fluid inclusions on chemical quality of NaCl...
