abstract little information is available concerning morphological responses of lolium perenne cultivars (numan and speedy green) to salinity and trinexapac-ethyl treatment in initial growth. in order to evaluate the effect of salinity treatment (0, 2000, 4000 and 6000 mg/lit) and trinexapac-ethyl levels (0, 50, 100 gr/ha) on morphological responses of 'numan' and 'speedy green' in initial growt...

This paper suggests that area studies and economics have a better chance to be married successfully if we shift our attention from the exclusive emphasis on economic growth towards improvements in human development, especially the much broadened version of that concept. Different areas are shown to differ substantially in terms of the choices they make among the various independent dimensions o...

During the dissolution of solid surfactants in water, various types of nonequilibrium microstructures have been observed. The most important one is the myelin growth which can be observed when some poorly water soluble surfactants such as phosphatidylcholine (PC), Aerosol-OT (AOT), etc. are contacted with water. In this study initial myelin growth for a period of 2-4 s is studied both qualitati...

The present study focuses on effects of initial pH on dibenzothiophene (DBT) desulfurization via 4S pathway by growing cells of Ralstonia eutropha. For so doing, temporal changes of biomass concentration, glucose as a sole carbon source, pH value, and 2-hydroxybiphenyl (2-HBP) formation have been monitored during the bioprocess. The biomass concentration has been modeled by the logistic equatio...

In two previous articles [Douady & Couder (1996a,b)] two iterative systems were defined, based respectively on hypotheses developed by Hofmeister (1868) and Snow & Snow (1952). It was shown that in the latter model all the variety of the spiral, whorled and multijugate patterns observed on botany could be obtained as steady regimes of the iteration. In this third article, several of the charact...

We test whether employment growth in a male worker's initial industry influences earnings using the 1979 National Longitudinal Survey of Youth. follow workers for 20 years after reporting their first industry, finding that lower implies substantially growth. Notably, controlling observable skills, controls family background and region have no impact on estimates. Effects appear larger occupatio...
