the low bioavailability of zinc (zn) is in calcareous and saline soil, therefore the study of chemical forms and bioavailability of zn in these soils is necessary to estimate the potential availability. the objective of this study was to evaluate the effect of plant growth promoting rhizobacteria and mycorrhizae fungi inoculation on the chemical forms of zn in a calcareous soil at different sal...

alzheimer’s disease (ad) is a neurodegenerative disease that was characterized with deposit of beta amyloid (aβ) aggregate in senile plaque. oxidative damage to neurons and loss of cholinergic neurons in forebrain region are observed in this disease. melissa officinalis is a medicinal plant from lamiaceae family, used traditionally in the treatment of cognitive disorders. it has cholinomimetic ...

From an analysis of the current world averages of the K→ ν̄l l (γ) and τ→ντ K − branching fractions, we derive, within the framework of type II Higgs doublets models such as the Minimal Supersymmetric Extension of the Standard Model, tanβ/mH < 0.21 GeV at a 90% confidence limit.

abstract the objectives of this research was to evaluate the rhizospheric effects of wheat (triticum aestivum l.) on the status of various inorganic p fractions and total organic p in 10 calcareous soils amended with 1% (w/w) municipal sewage sludge from the refinery of shahrekord city under rhizobox conditions. thus, wheat plant was planted in completely randomized design with three replicatio...

Attributable fraction (AF) is an important concept in clinical and epidemiological studies. The concept has mainly been discussed in relation to case–control studies, cross-sectional studies, and follow-up studies of fixed length. Here, we propose and discuss several ways of defining and estimating AFs with right-censored survival data, and thus with varying lengths of follow-up. In particular,...

background: due to multiple drug resistance against antimicrobial drugs for treatment of infectious disease, investigations to discovering new antibacterial compounds from natural sources have been designated. objective: according to antimicrobial effects of some capparis species, this study was carried out to evaluate the antimicrobial activity of the extract and fractions of capparis cartilag...

This article describes improved measurements by CLEO of the B0 → D+ s D ∗− and B0 → D∗+ s D ∗− branching fractions, and first evidence for the decay B+ → D (∗)+ s D̄∗∗0, where D̄∗∗0 represents the sum of the D̄1(2420) 0, D̄ 2(2460) 0, and D̄1(j = 1/2) 0 L = 1 charm meson states. Also reported is the first measurement of theD∗+ s polarization in the decay B 0 → D∗+ s D . A partial reconstruction tech...

We tested whether adults can use integrated, analog, magnitude representations to compare the values of fractions. The only previous study on this question concluded that even college students cannot form such representations and instead compare fraction magnitudes by representing numerators and denominators as separate whole numbers. However, atypical characteristics of the presented fractions...
