as sesame is a somewhat neglected crop, information concerning its response to salinity is lacking. the effects of nacl stress were studied on seven genotypes of sesamum indicum l. the 6-weeks-old sesame seedlings were treated with different nacl concentrations (0, 30, and 60 mm). the nacl caused significant decreases in fresh and dry mass of all genotypes; however responses of genotypes to the...

wastewater treatment and re-use of industrial process water are critical issues for the developmentof human activities and environment conservation. the present study was undertaken to evaluate the degradationof organic pollutants taking phenol as the model compound over aluminium pillared montmorillonite and therare earth exchanged analogues, underlining the use of environ friendly clay cataly...

for the first time, dioxomolybdenum(vi) complex with the general formula [moo2l2] containing a n-o bidentate ligands (hl=2-(o-aminophenyl)- benzimidazole) has been used for the oxidation of sulfides. elemental analyses (carbon, hydrogen, nitrogen), ft-ir and uv-visble spectra and 1hnmr analysis agree well with the proposed stoicheiometry of the complex [moo2l2].  a variety of sulfides were smoo...

the perovskite-structured la2cuo4 nanoparticles have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acid as organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles are characterized through fourier transform infrared spectroscopy, x-ray diffraction, scanning electron microscopy and transmission electron microscop...

several authors have indicated that pcp is a toxic chemical and recalcitrant to biodegradation. aops is one of the moste effective process for degradation of persistant compound.since the mineralization of recalcitrant compound by aops (advanced oxidation processes) often requires long reaction time and strong doses of oxidant, the combination of this process with biological one, considered as ...

conclusions to solve the above mentioned difficulties, fundamental study most be carried out to discover the novel methods of ferrate(vi) production, focusing on increasing the product stability and the production yield. results despite the existence of these technologies, there is no full-scale application of ferrate(vi) in the water and wastewater industry which it is due to difficulties asso...

An efficient synthetic method for successful synthesis of amine denderon on SBA-15 and related Pd (II) complex has been developed. This modified mesoporous material was characterized by various techniques such as TEM, XRD, atomic absorption spectroscopy, N2 adsorption-desorption, and FT-IR. The catalytic activities of the prepared catalysts were investigated by employing aerobic oxidation of al...

the oxidative modification of low density lipoprotein (ldl) may play an important role in atherogenesis. antioxidants that can prevent ldl oxidation may act as antiatherogens. our understanding of the mechanism of ldl oxidation and factors that determine its susceptibility to oxidation is still incomplete. copper is a candidate for oxidizing ldl in atherosclerotic lesions. the binding of copper...

the intake of antioxidants intake has been reported to be inversely associated with the incidence of coronary artery disease. to clarify the possible role of lipophilic antioxidants in prevention of atherosclerosis, we investigated the effects of lycopene on the susceptibility of low-density lipoprotein (ldl) to oxidative modification. in this study, “lycopene” was added to plasma and incubated...

a sodium dodecyl sulfate modified carbon paste electrode (sds/cpe) was developed in this work based on the surface modification method. the modified electrode was prepared by immersing sds/cpe in a nickel nitrate solution. this electrode showed a strong accumulation ability toward nickel ions. then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 v (vs. ...
