The main theme of this review is the importance of a discrete approach to describing rain at spatial scales comparable to inter-drop separation. We propose that the pair correlation function should be used to define and measure the texture of rain. To that end, we discuss the pivotal role of the Poisson process for examining this micro-structure of rain. The importance of statistical stationari...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
Carbon sequestration into plants biomass, especially in fast growing trees is an easier and economically way for dropping off CO2 from atmosphere. This study was carried out in order to investigate above-ground biomass of white poplar (populous alba, L.) plantations that was planted in fourdifferent plant spacing (0.5 × 0.5, 1×1, 2×2 and 4×4 m.) in Chaharmahal and Bakhtiari province in west of ...
This study assessed the intra and inter-rater reliability of a modified weight-bearing lunge measure of ankle dorsiflexion range of movement. Thirteen healthy subjects were recruited. Each subject performed 3 repetitions of the lunging method with one rater and 3 more repetitions with a second rater within 30 min. The process was repeated within 3 h. Intra-rater reliability results indicated ex...
AbstractObjectives: To assess the reliability and validity of the abridged version of the Farsi version of Scale to Assess Unawareness of Mental Disorders (SUMD), as well as examining the change in insight among patients with psychotic mania in the course of recovery. Method: In a cross-sectional study, 36 patients with psychotic mania were evaluated for inter-rater reliability by researchers. ...
Introduction: FAD is the cofactor of FAD-FR protein family. Sulfite reductase flavoprotein alpha-component is one of the main enzymes of this family. Based on applications of this enzyme in biotechnology and industry, it was chosen as the subject of evolutionary studies in 19 specific species. Method: Gene and protein sequences of sulfite reductase flavoprotein alpha-component, 5S rRNA sequence...
In the present study, the concentrations of three volatile organic compounds (VOCs), namely, acronym for benzene, toluene, and xylenes (BTX) were assessed because of their role in the tropospheric chemistry. Two representative sites, a roadside and a petrol pump, were chosen for sample collection. VOCs were collected using SKC-activated charcoal tubes and SKC personal sampler and characterized ...
One of the biggest advances in recent years for high-dimensional copula models and applications has been the development of the vine pair-copula construction that covers continuous and discrete variables, and its extensions to include latent variables. Software has been made available in the VineCopula R package and the package that is companion to the book by Joe [6]. This special issue of the...
The goal of this research is to indirectly estimate carbon storage. Carbon sequestrations by the trees in the Pine, ash and false trees-planted areas of Chitgar Forest Park in Tehran, Iran, were estimated by using of GeoEye-1 images. 102 sample areas of 25×20m have been measured using Systematic Random Sampling (SRS) method for the study. The Biomass and carbon sequestration for each sample wer...
conclusions pine trees can be used as a worthy bio-indicator for hms pollution monitoring in the ambient air in areas with extensive vegetation of pine trees. results iron had the highest concentration (345.0053 mg/kg) in leaves when compared with other hms. the concentration of zn, cu, pb and cd were 26.1384, 5.5905, 2.9963 and 0.7383 mg/kg, respectively. spatial mapping indicated that industr...
