given the important role of crop growth indices for explanation of cultivars yield differences in diverse environmental and agronomical circumstances, this experiment was conducted at research field of tarbiat modares university during 2007 growing season. experimental treatments were arranged in split-plot layout based on randomized complete blocks with four replications. in this research, sow...

ABSTRACT Digitalization transforms the traditional concepts of economic growth and competitiveness. This article studies effect digitalization on Russia’s growth. As indicators measuring impact processes growth, study used Gross Domestic Product per capita, Global Competitiveness Index, Index Digital Life, Adoption Resilience Index. Their in-depth examination based a three-pronged model showed ...

Environmental issues and risk have become central in socioeconomic research and policy planning in order to ensure sustainable development. As environmental risk is difficult to assess and measure, different indexes have been developed to evaluate specific aspects of such risk. Environmental risk typically involves problems generated by the consumption of energy (fuels), water shortages, disast...

this paper aims to study the relationship between intellectual property and patent and economic growth in islamic countries for the period of 1990 – 2010. this theoretical basis of the model is constructed on economic growth models in 1990s. the technique which we employed is the index of patents to measure the impact on economic growth. to analysis this relationship we use “pedroni cointegrati...

to investigate the effects of methyl jasmonate growth regulators on growth characteristics, fruit number and fruit yield of ‘semsuri’ melon, an experiment at the field of shahid bahonar university was conducted in summer 2012. melon (cv. ‘semsuri’) is widely cultivated in iran and therefore increasing the fruit yield and quality of this cultivar is necessary. some growth regulators including me...

OBJECTIVES To determine the influence of birth weight on body mass index at different stages of later life; whether this relation persists after accounting for potential confounding factors; and the role of indicators of fetal growth (birth weight relative to parental size) and childhood growth. DESIGN Longitudinal study of the 1958 British birth cohort. SETTING England, Scotland, and Wales...

Two measures of stability based on longitudinal growth data are described. One, termed a growth constancy index, is based on the variation of each individual's (standardized) measurement about his or her average. The other, called a growth separation index, measures the extent to which individual growth curves cross each other. The uses of these indices are described and formulae for calculatin...

AIM The aims of this study were to compare ultrasound fetoplacental parameters and to calculate Hepato-Cephalic Index (HCI) as a new predictor of IUGR. METHODS AND MATERIAL A clinical prospective study was conducted and included 120 pregnant women divided in two groups: non IUGR group included healthy pregnant women (n=60) and IUGR group included pregnant women with preeclampsia and IUGR (n=6...

| December 2015 | 1218 In spite of an emphasis on high quality and quantity of Iranian publications in this article,[2] it should be noted that the complete cycle of science is not summarized in the first chain (science-production). Indeed, the production of technology and the achievement of economic development should be put in the context of scientific and research activities. Scientific prog...

We use the new approach of braiding sequences to prove exponential upper bounds for the number of Vassiliev invariants on knots with bounded braid index, bounded bridge number and arborescent knots. We prove, that any Vassiliev invariant of degree k is determined by its values on knots with braid index at most k+1.
