intra-specific variations in apex development of two salt-tolerant cultivars (cross rowshan 11 (cr) and kharchia-65) and one salt-sensitive cultivar (ghods) of spring wheat (triticum aestivum l.) grown in sand culture at selected levels of salinity (0, 100, 200, and 300 mol m-3 nacl and cacl2 in 5:1 molar ratio) were studied. to determine the apex lengths and the number of spikelet primordi...

glomerular development of the kidney was studied in newborn rats by electron microscopy. four different stages of glomerular development were defined: vesicle fonnation, s-shaped body stage, capillary loop fonnation, and glomerular maturation. in the fust stage, the mesenchymal cells form a spheroid mass. this is followed by the s-shaped body stage in which clefts appear in the mass. afterwards...

this experiment contained four vetch lines (vicia panonica ) that conducted in two locations (faruj and bojnourd) in 2005-2006 in rcbd design with four replications under dryland conditions. analysis of variance indicated that there were significant differences among lines in different locations about all traits, except 100-seed weight. the interaction of genotype×location was significant on al...

type, even at this level we can only determine state structures and policies insofar as they are necessitated by the dominant mode of accumulation. Thus, to a large extent, the content of the theory of the state must be developed at the historical level of analysis. A purely capitalist society is conceived of as a global society without external relations, but this is a high level of abstractio...

I want to talk this afternoon about problems of economic development and the special problems of extreme poverty, and relate them to the international issues, as well as to China’s development problems. Development economists try to understand why some parts of the world remain stuck in extreme poverty, why others grow out of extreme poverty but get stuck at certain levels, and why others achie...
