abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Crop depends on its canopy to intercept solar radiation to drive both assimilation and water, nutrient absorption for its growth. Field experiments, involving three sowing time and three sowing rate, were conducted at Luancheng Station to investigate the effects of canopy size and development on crop growth and radiation use efficiency (RUE) of winter wheat during 2009/2010 and 2010/2011 gr...
Back ground: Although the cell differentiation is an inseparable part of development in multicellular organisms, the regulating molecular pathway of it still is not fully defined. In the other hand, apoptosis is a fundamental physiological process which plays an essential role in a variety of biological events during development. Moreover, recent studies have found that apoptosis shows several ...
Background and Purpose: "Executive functions" is a general term and contains components which form a common pattern while being distinctive form each other at the same time. These functions imply the ability to use higher cognitive processes to focus on the significant aspects of the task and to plan for its completion. During the recent years, a general view has been developed indicating that ...
Skeletal patterning in the vertebrate limb, i.e., the spatiotemporal regulation of cartilage differentiation (chondrogenesis) during embryogenesis and regeneration, is one of the best studied examples of a multicellular developmental process. Recently [Alber et al., The morphostatic limit for a model of skeletal pattern formation in the vertebrate limb, Bulletin of Mathematical Biology, 2008, v...
Notochord is an axial structure derived of embryonic mesoderm and in addition to structural supporting role in inducing nearby germinal layers, it has a basic role in formation of organs such as vertebral column, axial vessels, neural tube and primitive gut. This organ undergoes essential changes during the development process. First, arises from the primitive node and terms notochordal process...
information systems (is) and the process of distinguishing information systems ontology have been the center of challenge during the 50 years of is development. the importance of this challenge is emergent in direct link between knowledge development process in is and the is ontology. in other words, theorizing and efforts to falsify theories, which have been developed, is influenced by the way...
