Parity-conserving and -violating response functions are computed for the inclusive electroexcitation of the N∗(1440) (Roper) resonance in nuclear matter modeled as a relativistic Fermi gas. Using various empirical parameterizations and theoretical models of the N −N∗(1440) transition form factors, the sensitivity of the response functions to details of the structure of the Roper resonance is in...

Vermicomposts processed commercially from food wastes and paper wastes were applied, to 4.5 m(2) field plots, under high plastic hoop tunnels, at rates of 5 or 10 tha(-1) to evaluate their effects on the growth and yields of strawberries (Fragaria ananasa) var. 'Chandler'. The vermicomposts were incorporated into the top 10 cm of soil and supplemented, based on chemical analyses, with amounts o...

The hydrogen-bonding patterns in crystal structures of unprotected, zwitterionic dipeptides are dominated by head-to-tail chains involving the N-terminal amino groups and the C-terminal carboxylate groups. Patterns that include two concomitant chains, thus generating a hydrogen-bonded layer, are of special interest. A comprehensive survey shows that dipeptide structures can conveniently be divi...

The immunosuppressive activity of spergualin analogues, 15-deoxyspergualin and N-30, is presented. These compounds suppressed antibody formation and establishment of delayedtype hypersensitivity to sheep red blood cells (SRBC) in mice. Amongspergualin, 15-deoxyspergualin, and N-30, 1 5-deoxyspergualin was most effective in suppressing immuneresponses. It suppressed antibody formation against SR...

This study aimed to evaluate the efficiency of energy consumption and economic analysis of different watermelon cultivation systems in Fars Province of Iran. Watermelon production systems were classified into five systems, namely, custom tillage (group 1), conservation tillage (group 2), traditional planting (group3), semi mechanized planting (group 4), and mechanized planting (group 5). Data w...

in order to investigate the effects of input intensity on species diversity, composition and density of weeds in corn (zea mays l.), an experiment was conducted based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, iran during the year 2009. treatments included low input, medium input and high input systems. low...
