in order to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in isfahan. the experiment was conducted as split plots in a randomized complete blocks design with three replications in isfahan (51° 48' e, 32° 40' n).main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class a and cultiv...
abstract soil salinity in huge parts of the world, especially in arid and semi-arid regions, is a factor limiting growth of plant and other organisms. earthworm can be considered as an indicator of soil quality in agroecosystems, because of a positive correlation between earthworm abundance and the productivity of cropped plants. the main objective of this study was to realize the interaction b...
Introduction: Corruption, as a deterrent to equitable development, is recognized as a contentious issue in the field of institutional quality and political economy. The literature on the impact of corruption on economic growth often addresses the issue that corruption has had a negative impact on economic growth and development. But some economists believe that corruption has had a positive eff...
Soil salinity is an increasing environmental stress on crops in most areas of Iran since farmers use underground saline water for irrigation. In order to investigate the effects of salt stress on germination and seedling growth of safflower (Carthamus tinctorius L.), an experiment was conducted at two stages (germination seedling growth), using four levels of NaCl salinity (0, 5, 10, 15 ds/m), ...

The most desirable approach to improve characteristics such as yield with polygenic inheritance and genotype × environment interaction, is simultaneous selection using selection index based on related traits. This study was conducted Research Farm of Isfahan University of Technology, to compare selection indices for barley yield improvement under nitrogen stress and non stress conditions, usi...

the main challenge of developing countries, is achieving growth and development. review of economic growth literature shows that the quality of institutions and social infrastructure are important factors that influence the economic growth and development. also many analysts believe that between institutional factors, the rule of law is one of the most elements for appropriate system for invest...
Recently, some efforts focus on differentiating dark energy and modified gravity with the growth function δ(z). In the literature, it is useful to parameterize the growth rate f ≡ d ln δ/d ln a = Ωm with the growth index γ. In this note, we consider the general DGP model with any Ωk. We confront the growth index of DGP model with currently available growth rate data and find that the DGP model ...
