Background: Some metals play an important role in  biological reactions  and metabolism of human body. Low and high concentrations of these elements can cause diseases and poisoning. This study was carried out in order to investigate the concentration of metals in inlet and outlet water of households in Ahvaz city, Iran in 2018. Materials and Methods: This was a cross-sectional descriptive stud...

Among abiotic stresses, soil and water salinity are the major factors affecting agricultural crops growth and productivity worldwide. On the other hand, the scion-rootstock combination and also foliar application of chimical compounds as salicylic acid can affect the nutrient elements content of almond leaf under salinity conditions. Therefore, in this study, the effects of foliar application o...

Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction  and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essen...

The paper reports on the use of phonon spectra obtained with the Raman spectroscopy for characterization of different materials. The Raman scattering spectra obtained for zinc selenide crystals, mixed crystals zinc selenide admixtured with magnesium or beryllium, oxide crystals including strontium lanthanum gallate, molecular crystals of triammonium hydrogen diseleniate and a homologous series ...

In the last decade, iron and magnesium, both pure and alloyed, have been extensively studied as potential biodegradable metals for medical applications. However, broad experience with these material systems has uncovered critical limitations in terms of their suitability for clinical applications. Recently, zinc and zinc-based alloys have been proposed as new additions to the list of degradable...

The first magnesium, copper and zinc disilenides were prepared via transmetallation reactions of a lithium disilenide and structurally characterised. The copper and zinc derivatives show red-shifted UV/vis absorptions due to admixture of metal d-orbitals to the highest occupied molecular orbital.

This study investigated the effects of different levels of manganese and zinc sulfate on the quantitative and qualitative characteristics of three irrigated wheat (Triticum aestivum L.) varieties in the Abstan region of Zagheh section of Khorramabad city in 2008-2009. The experiment was performed factorially on the basis of a randomized complete block design with three replications. Treatment...
