abstract nickel is a heavy metal distributed ubiquitously in nature. it accumulates in soil as a result of human activities, including mining and industries development. it may be poisonous to plants, humans, animals and microorganisms. the present study was implemented as a factorial experiment with a randomized complete block design (rcbd), of three replications in calcareous soils of karaj a...
to investigate the effects of sowing date on yield and quality of six forage maize cultivars in rasht region, a field study was conducted in 2010. the experimental design was a randomized complete block using a factorial arrangement with three replications. treatments consisted of four levels of sowing date (22 may, 3, 15 and 25 june), and six maize cultivars (sc 260, dc 370, sc 500, sc 647, sc...

in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...
peppermint (mentha piperita l.) from lamiaceae family is one of the most important medicinal plants, used in food, sanitary and cosmetic industries. a field experiment was carried out in ferdowsi university of mashhad in 2010-2011 to evaluate the effects of three irrigation levels (100, 80 and 60 percent of water requirements calculated by evaporation pan class a) and two mulch types (black pla...
This study was conducted to determine some physiological parameters of maize cultivar KSC 704 affected auxin and cytokinin hormones concentration variations under drought stress condition. The experiment was carried out in three environments separately including non-drought stress environment, drought stress in vegetative stage and drought stress in reproductive stage. Cytokinin hormone in thre...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
To study the effects of plant density and species on forage and grain yield of Vicia sp., anexperiment was conducted in College of Agriculture, University of Lorestan, under dry farming conditions during 2007-2008 growing season. Three levels of plant density at 100, 150 and 200 seed per square meter along with three species of Vicia including Vicia narbonensis, Vicia sativa and Vicia dasycarp...
to achieve optimal yield and high production in wheat, need to adapt the plant's vegetative and reproductive growth stages to environmental conditions and increase use efficiency of production factors by desirable density. in order to study the effect of plant density on extinction coefficient and radiation use in modern and old wheat (triticum aestivum l.) genotypes, an experiment was conducte...
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...
