作者： Zalak Shah Keval gandhi Ajay Kumar Rai Department of Applied physics Sardar Vallabhbhai National Institute of Technology

We present the masses of N baryons up to 3300 MeV. The radial and orbital excited states are determined using hypercentral constituent quark model with the first-order correction. The obtained masses are compared with the experimental results and other theoretical predictions. The Regge trajectories are also determined in(n, M^2) and(J, M^2) planes. Moreover, the magnetic moments with J^p =(1^+/2,1^-/2) are calculated. We also calculates the Nπ decay width of excited nucleons.

propoxur is a widely used dithiocarbamate insecticide. In this study, the clastogenic effect of propoxur has been evaluated using chromosomal aberration assay in mouse bone marrow cells. Single i. p. administration of propoxur, at 25 mg/kg ***., a maximum tolerated dose (MTD) and 12 .5mg/kg *** (50% of MTD) have significantly induced different types of aberrations after 24 h of treatment. The aberrations were dose and time dependent and reached a maximum after 24 h of exposure. The sresult suggest a genotoxic potential of propoxur.
