in this study we investigate the effect of atoms such as b, n, ge and sn on the optical and the electrical properties of capped (5, 0) zigzag carbon nanotube, using dft calculation method. these elements were attached to the one end of the carbon nanotube. we considered four different structure designs as possible candidates for a p-n junction device. the electrical properties of these structur...

background: prolonged inhibition of acetylcholine esterase may lead to the intermediate syndrome. neuromuscular junction (nmj) dysfunction has been shown with repetitive nerve stimulation (rns). subclinical nmj dysfunction may also occur. we aimed to examine the nmj function following acute organophosphorus (op) poisoning by using exercise modified slow rns. methods: a cohort study was conducte...
