the aim of this research is to classification of soil seed bank in populus caspica protected area. the study of above ground vegetation and soil seed bank were carried out with braun-blanquet and seedling emergence method respectively. results showed that size of soil seed bank in upper layer (713 seeds per m2) were significantly lower than depth layer (1163 per m2) but species richness from 42...

this study was carried out to determine some mechanical properties of barley seed including deformation, rapture force, rapture energy and toughness as a function of moisture content (10.5%, 12.5%, 14.5% , 16.5%, db), loading rate (5, 15, 25, 35 mm.min-1) and grain size (small, medium, large). tests were performed at 7 replications by the means of a factorial base plot experiment. the results s...

this study was carried out in order to identify the effects of soil water depletion (swd) on monogerm sugar beet (cv. shirin) seed growth trend at different growth stages. an experiment was conducted in randomized complete block design (rcbd) with three replications in ardebil agricultural research station. during 2002 and 2003 cropping seasons, nine treatments including control (irrigation aft...

This contribution to the XVth Quark Confinement and Hadron Spectrum conference covers a description, both theoretical experimental, of present status set very different anomalies. The discussion ranges from long standing $b \to sll$ anomalies, $(g-2)$ new $M_W$ anomaly.

Interpopulation variability in seed traits may drive the regeneration capacity of a species to colonize different environments. In present study, we evaluated variation physical (mass / size, water imbibition, shape index) and physiological (germination) five Polygonaceae species. Seeds Polygonum lapathifolium var. salicifolium , P. Reynoutria japonica Rumex trisetifer R. obtusifolius were coll...

In this paper, we study the Multi-Round Influence Maximization (MRIM) problem, where influence propagates in multiple rounds independently from possibly different seed sets, and the goal is to select seeds for each round to maximize the expected number of nodes that are activated in at least one round. MRIM problem models the viral marketing scenarios in which advertisers conduct multiple round...
