environmental variables, including soil water content (swc), act as constraints on crop growth and productivity. therefore, open air (e0), perforated (e1) and non-perforated (e2) plastic housings were used with well-watered (w0), moderately-watered (w1) and water-stressed (w2) bush bean plants to explore the relationships between water-use efficiency (wue), carbon isotope discrimination (δ) and...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
The random-cluster model has emerged as a unifying framework for studying random graphs, physical spin systems, and electrical networks [6]. Given a base graph G = (V,E), the random-cluster model consists of a probability distribution π over subsets of E, where p ∈ [0, 1] and q > 0 are real parameters determining the bond and cluster weights respectively. For q ≥ 1, there is a value of p = pc a...
The deprotonation constant of glycine in 10%, 20% and 30% dioxane dioxane-water system at 298.15 K was determined using the cell: H2(Pt) | Glycine, HCl, X% Dioxane, Hg2Cl2 Hg …(C-1) m1 m2 e.mf. cell given by E = E0 - (2.303RT/F) (log mH+ mCl_ + log ?H+ ?Cl_) …(1) where ?Cl_ (2A’√μ/(1+√μ) ) ?1μ (Modified Davies Equation) …(2) which has been B Prasad our laboratory called modified equation for ca...
Several studies have projected increases in drought severity, extent and duration in many parts of the world under climate change. We examine sources of uncertainty arising from the methodological choices for the assessment of future drought risk in the continental US (CONUS). One such uncertainty is in the climate models' expression of evaporative demand (E0), which is not a direct climate mod...
The asymptotics of the Gell-Mann – Low function in QED can be determined exactly, β(g) = g at g → ∞, where g = e is the running fine structure constant. It solves the problem of pure QED at small distances L and gives the behavior g ∼ L. According to Landau, Abrikosov, Khalatnikov [1], relation of the bare charge e0 with the observable charge e in quantum electrodynamics (QED) is given by expre...
The article presents the analysis of ArICl(IP,vIP,nIP) population and decay at energies lower than ArICl(E,vE = 0,nE) dissociation limit (IP E0+, D?2, ?1), vIP 0, 1, nIP are quantum numbers van der Waals (vdW) modes). It shows that lifetimes determined spectral ranges where ArICl(E?X, D??A?, ??A) luminescence takes place, same, ? 20.3 ± 1.0 ns, i.e. strongly mixed complex states populated in Ar...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
