Positron annihilation lifetime spectroscopy and positron-electron momentum density (PEMD) studies on multilayers of PbSe nanocrystals (NCs), supported by transmission electron microscopy, show that positrons are strongly trapped at NC surfaces, where they provide insight into the surface composition and electronic structure of PbSe NCs.Our analysis

Each hydraulic hoist of eccentric trunnion sector gate consists of Course a pied - Accessoires - Etui a telepnone two sets of cylinders and one set of hydraulic pump station.Bladder accumulators are used to supply oil into cylinders when leakage occurs to prevent the gate from sinking.Instead of traditional slide valves, cartridge valves are used t

We explored the immunoreactivity of choline acetyltransferase (ChAT) in the cranial nerve motor nuclei of the Planner porcine rhombencephalon to reveal the cholinergic nature of these regions.In our experiments we used an immunohistochemical method for the visualization of all acetylcholine-containing structures.All studied motor nuclei contained C

Quantitative resistance in barley to four Fusarium head blight (FHB) species was investigated in vitro.Nine components involved in three assays (detached leaf, modified Petridish and seedling tests) were compared on two widely grown Syrian barley cultivars: Arabi Aswad (AS) and Arabi Abiad (AB).On AB, inoculation with FHB species resulted in a sign
