The present work consists of deducing the point kinetics model considering neutron absorber poisons from diffusion equation. When products, non-linear system has different orders magnitude in short and long time scales. first one represents operational reactor control, whereas second is due to change chemical composition nuclear fuel as a result burn-up. This step new direction, it shows how we...
Introduction: Due to dissimilarities in the availability of poisons in different areas and lack of enough control over the purchase and sale of some dangerous rodenticides, it is prudent to establish the distribution of rodenticide poisoning in each region. Therefore, this study was performed to evaluate the demographic factors, types of poisons, duration of hospitalization and mortality of pat...
Little is known about the magnitude of the effects of lead shot ingestion alone or combined with poisons (e.g., in bait or seeds/granules containing pesticides) on population size, growth, and extinction of non-waterbird avian species that ingest these substances. We used population models to create example scenarios demonstrating how changes in these parameters might affect three susceptible s...
