abstract the current research tried to examine the impact of multiple intelligence (mi) and its components on multiple choice (mc) and open ended (oe) reading comprehension tests. ninety six students of high school in grade four took part in this study. to collect data, participants completed multiple intelligence (mi) questionnaires along with a multiple choice (mc) and open ended (oe) forms ...
The aim of the current research was to evaluate heavy metals contamination in Kurdish rice from main rice-producing areas Kurdistan and its health risk assessment. samples were collected different locations concentration measured by using Inductively Coupled Plasma-optical emission spectrometry (ICP-OES). Estimated Daily Intake (EDI) also calculated potential assessment for local population thr...
In the present communication, analysis of various heavy metal (Cr, Fe, Cu, Zn, As, Se, Cd, Pb and Th) concentrations in 10 drinking water samples collected from the diverse locations from different depths of Nagaur district of Rajasthan, India has been carried out by using high resolution inductively coupled plasma mass spectroscopy (HR-ICP-MS) technique. The water samples were taken from hand ...
The assessment of heavy metal contaminants: Mn, Cr, V, Cu, Pb, Zn and Ni, was conducted on River Niger Floodplain soil at Jebba, Central Nigeria using Contamination Factor (Cf), Factor (AF), Enrichment Factor (EF), Geoaccumulation Index (Igeo) and Degree of Contamination (Cdeg). Random sampling method was adopted cutting across the entire floodplain and the samples were subjected to Inductively...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
abstract this study aimed at investigating the translation of interjections from english into persian in dubbing. to carry out this study the expressive secondary interjections found in the film four weddings and a funeral and their equivalent in persian dubbed version were analyzed through the strategies proposed by cuenca. the descriptive analysis of the corpus showed that (strategy b) i.e...
Introduction: Uncontrolled and improper landfilling of solid waste increases the concentration of heavy metals in the soil. Therefore, this study aimed to investigate soil contamination with heavy metals in the landfill of municipal and hospital waste in Sabzevar city by compiling a map of the severity of heavy metal pollution in the soil. Materials and Methods: Concentrations of heavy metals ...
در این تحقیق، تاثیر مواد افزودنی گل و سازندهای حفاری شده در غلظت فلزات پسماندهای حفاری چاه 449 میدان نفتی اهواز مورد بررسی قرار گرفت. نمونهبرداری از مواد افزودنی گل، گلهای حفاری، پسماند (گل+خرده) سازندهای حفاری شده و همچنین خاکهای اطراف منطقه حفاری صورت گرفت. پس از آمادهسازی نمونهها، برای تعیین غلظت فلزات از روشهای ICP-MS و ICP-OES استفاده شد. نتایج نشان میدهد که باریت منشا فلزات C...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
algae have been proven efficient biological vectors for heavy metal uptake. in order to further study their biosorption potential, two strains spirogyra sp. and spirulina sp. have been studied under different initial metal concentrations. in recent years, the biosorption processes have been studied extensively using microbial biomass as biosorbent for heavy metal ions removal. in these studies,...
