fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...

abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
In order to investigate the effects of rates and nitrogen fertilizer application timing on yield and some growth physiological indices of corn ( Zea mays L.), an experiment was conducted as split plot based on randomized complete block design with three replications at the Research Farm of University of Mohaghegh Ardabili during 2009 cropping season. Nitrogen fertilizer levels were arranged in...
In order to study the effects of seed inoculation with plant growth promoting rhizobacteria (PGPR) and foliar application of nano-zinc oxide (NZO) on yield and rate and period of grain filling of triticale, a factorial experiment was conducted based on randomized complete blocks design with three replications, in Research Greenhouse of Faculty of Agriculture, University of Mohaghegh Ardabili, I...
The objective of this research was to study the effects of draught stress and Fe fertilizer on some physiologic and biochemical characteristics in chickpea (Cicer arietinum L.). This study was conducted at Campus of Agriculture and Natural Resources, Razi University, Kermanshah, Iran, during 2011-12. The experiment laid out as split plot based on RCBD with three replications. Rainfed and withou...
