Hawking evaporation of black holes in the early Universe is expected to copiously produce all kinds particles, regardless their charges under Standard Model gauge group. For this reason, any fundamental particle, known or otherwise, could be produced during hole lifetime. This certainly includes dark matter (DM) particles. paper improves upon previous calculations DM production from primordial ...

Agricultural practices affect arbuscular mycorrhizal fungal (AMF) hyphae growth and glomalin production, which is a recalcitrant carbon (C) source in soil. Since the spatial distribution of an interesting issue for agronomists terms sequestration, digital maps are cost-free useful approach. For this study, set 120 soil samples was collected from experimental area 310 km2 Sarab region Iran. Soil...
