In order to investigate application of nitrogen rates at different growth stages effects on dry matter remobilization and effective traits at dry matter accumulative of grain in spring barley (Hordeum Vulgare L.), an experiment was conducted as factorial based on randomized complete block design with three replications at the research farm, University of Mohaghegh Ardabili during 2012 cropping....

In order to investigate the effect of methanol on the activity of antioxidant enzymes, some compatible osmolytes and biochemical traits of wheat under cut off irrigation conditions, the present experiment as factorial was conducted based on randomized complete blocks design with three replications at the research farm of Faculty of Agriculture and Natural Resources of University of Mohaghegh Ar...

Supplementary irrigation is one of the most effective field management practices to improve water productivity and crop yield in rainfed conditions. Time of supplementary irrigation is another important parameter affecting the enhancement of yield. In order to study the effect of supplementary irrigation time as well as planting date, two factors, namely: 1) supplementary irrigation (No irrigat...

there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...

abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...

in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
