Background: During breast three fields radiotherapy, the problem is that the divergency of the field interferes with matching the edges. So the matching point of these supraclav and tangential field will suffer from over-dose and under-dose. To prevent these these divergency, a half- block is often applied at supracluv field. Also in some techniques like collimator and couch rotation, corner bl...

in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...

In an experiment the effective dose and the time of application of phenamiphos (Nemacur 10G) for control of the root knot nematode, Meloidogyne javanica, infecting cucumber, was found out to be 22.5 g/m2 of commercial product and the best time of its application was one week prior to sowing of seeds. However, the results revealed that in concomitant and sequential (one week before) treatment, h...
