abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
Background & Aim: The present study was to identify the medicinal plant species and introduced as one of the key priority areas for conservation and determination of endangered species were done. Experimental: The method of plant collection in this region was classical method of regional plant taxonomic studies. Collected plants were recognized and determined families, genera and species of th...

Background & Aim: Kazeroon, with an area of about 4060 km², is situated at 110 km in the west of Shiraz, Fars province, Iran. This area is important for plant biodiversity, due to the presence of some important habitats such as international Lake of Parishan in the southeast, woodlands of Quercus persica in the east and branches of Shahpoor river in the west of the region. Therefore, f...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
rangeland ploughing and cultivation using dry land farming crops may be amajor reason for the destruction of natural resources in the semiarid and sub-humid regionswhich may significantly change the composition and reduce the stability of the affectedcommunities. in present research, an abandoned ploughed site was compared with a nearbyreference site in the semiarid rangelands of baharkish, quc...
Abstract Background and purpose: Vulvovaginal candidiasis (VVC) often referred to as a yeast infection which is a common gynecologic problem, affecting %75 of women during their lifetimes. More than 40% of affected women will have two or more VVC episodes. Candida albicans is the most common agent of VVC however non-albicans Candida species have increasingly been identified as the cause of v...
Arable areas are commonly susceptible to alien plant invasion because they experience dramatic environmental influences and intense anthropogenic activity. However, the limited reports on relevant factors in plant invasion of croplands have addressed single or a few invasive species and environmental factors. To elucidate key factors affecting plant invasions in croplands, we analyzed the relat...
Differences in ionomic responses to nutrient deficiencies among plant species under field conditions
The ionome is defined as the mineral element composition of an organism or tissue and genetically environmentally influenced. Although nutrient deficiency changes plant ionome, differences among different species have not been elucidated fully. In present study, we examined ionomic responses to in wheat (Triticum aestivum L.), maize (Zea mays sunflower (Helianthus annuus soybean (Glycine max (L...
