Ten cadmium resistant marine bacterial isolates were isolated from seawater and sediments samples of Hurghada harbour on a seawater nutrient agar medium amended by 25 ppm of cadmium and tested for their resistance to higher cadmium concentrations (up to 200 ppm). The most resistant isolate which was able to grow at 150 ppm was identified on the basis of its morphological, physiological and bioc...

Emissions of manganese (Mn), lead (Pb), iron (Fe), zinc (Zn), copper (Cu) from ferro-alloy operations has taken place in Valcamonica, a pre-Alp valley in the province of Brescia, Italy, for about a century until 2001. Metal concentrations were measured in the soil of local home gardens and in the cultivated vegetables. Soil analysis was carried out using a portable X-Ray Fluorescence (XRF) spec...

scion-rootstock combination and level of salinity affect growth characteristics and concentration of nutrition elements of almond leaves and roots. in this research, effects of salinity stress were investigated on growth characteristics and nutrient concentration of almond leaves and roots by completely randomized design (crd), with two factors, genotype and water salinity with three replicatio...

the arghash area is located 45 km to southwest of neyshabour. the subvolcanic rocks in the area consist of biotite hornblende quartz monzodiorite porphyry, hornblende biotite quartz monzodiorite porphyry, hornblende monzonite porphyry, biotite hornblende monzonite porphyry, monzodiorite porphyry and biotite quartz monzodiorite porphyry units. the volcanic rocks consist of hornblende biotite dac...

Copiapite-group minerals of the general formula AR4(SO4)6(OH)2d nH2O, where A is predominantly Mg, Fe , or 0.67Al, R is predominantly Fe, and n is typically 20, are among several secondary hydrous Fe sulfates occurring in the inactive mine workings of the massive sulfide deposit at Iron Mountain, CA, a USEPA Superfund site that produces extremely acidic drainage. Samples of copiapite-group mine...

Considering global warming as a major constraint of yield and quality, the present study accessed impact terminal heat stress on wheat stability grain Fe Zn content in wheat. Twenty-three genotypes CGIAR Research Program (CRP) two check varieties, PBW343 HD2967 were evaluated for under conditions at stage. Stability measures indicated CRP7, CRP8, CRP33, CRP46, CRP48 to be most stable genotypes....

The inhibition efficiency (IE) of an aqueous extract of beet root (BR) in controlling corrosion of carbon steel in well water in the absence and presence of Zn 2+ has been evaluated by mass loss method. The formulation consisting of 4 mL of BR extract and 50 ppm Zn 2+ offers 98% inhibition efficiency to carbon steel immersed in well water. A synergistic effect exists between BR extract and Zn 2...
