We believe that these comprehensive comments address the many weaknesses in the proposed PHG requiring further evaluation and appropriate change to the proposed PHG at this time. We further believe that the now ongo...

propene dissociation channels were characterized by ab initio ccsd(t)/6-311++g(d,p) calculations. inthis work the detailed mechanism of propene dissociation to c2h4+ch2, c2h2+h+ch3, c2h2+ch4 andc3h3+h2+h have been investigated. according to our calculations, ten fragments can be classified intofive dissociated channels. our results point out that two mechanisms come into play in the h2 eliminat...

Alveolar macrophages (AM) from bovine lungs were exposed in culture to manual metal are (MMA) welding fume particles, chromium (Cr), UICC chrysotile A or anatase for 17-20 hr. All the welding particle samples were more cytotoxic to AM than to anatase. Particles from the welding of mild steel with a rutile-coated electrode were less cytotoxic than those produced with a basic-coated electrode. Pa...

background: asymptomatic malaria infection provides a reservoir of parasites, causing the persistence of malaria transmission. it accounts an important challenge for successful management of the control, elimination, and eradication programmes in any malaria-endemic region. this investigation was designed to assess the presence and the prevalence of asymptomatic carriers in iranshahr district o...

this study was undertaken to identify key elements for obtaining community interest and motivate them to support eliminate malaria in the places that malaria is no longer a perceived threat.sequential explanatory mixed methods research design used to provide more comprehensive evidence research. a questionnaire was developed after reviewing the literature relating to community participation for...
