Abrupt autofocusing performance of a circular Airyprime beam (CAPB) with vortex pairs propagating in free space is investigated.Here the vortex pairs are off-axis by default.The influences of topological charges and spatial location of vortex pairs on abrupt autofocusing behaviour of a CAPB with vortex Sculpture pairs are evaluated by numerical sim

Electrode potentials in AL-Zubare harbor water (South -Gas Company),of 23.88 ohm-cm at 20oC were reported for 26 HBS metals and alloys includingvalues for electroless nickels that signify a greater passivity than steel.Thelarge potential difference between steel and electroless nickel predicts severegalvanic corrosion, which was confirmed by weight
Pyrrolizidine alkaloids (PAs) are a widespread group of secondary metabolites in plants.PAs are notorious for their acute Outdoor End Table hepatotoxicity, genotoxicity and neurological damage to humans and animals.In recent decades, the application of PAs for beneficial biological activities to cure disease has drawn greater attention.Here, we rev
Many insects are influenced by the phenology of their host plants.In North Central Florida, Narnia femorata (Hemiptera: Coreidae) spends its entire life cycle living and feeding on Opuntia mesacantha ssp.lata.This cactus begins producing flower buds in April that lead to unripe green fruit in June that ripen into red fruit through December.Many mor
