Agricultural intensification has drastically altered foraging landscapes for bees, with large-scale crop monocultures associated floral diversity loss. Research on bumblebees and honeybees shown individuals feeding pollen from a low richness of sources can experience negative impacts health longevity relative to higher source similar protein concentrations. Florally rich are thus generally assu...

ABSTRACT We develop a high-performance analytical model of Galactic Chemical Evolution, which accounts for delay time distributions and lock-up stellar yields in thermal-phased ISM. The is capable searching, the first time, through high-dimensional parameter space associated with r-process enrichment Milky Way by its possible sources: Neutron Star Mergers Collapsar events. Their differing forma...

background: prompt gamma neutron activation analysis (pgnaa) is known as a non-invasive technique capable of measuring elemental concentration in voluminous samples in a short period of time. also it is a valuable diagnostic tool for total body elemental measurements. 252cf and 241am-be sources which are usually used in this method, generate not only neutrons, but also emit high-energy and unwa...
