Background: Sulfur mustard (SM) as a chemical warfare agent, increases permeability of bronchial vessels and damages airway epithelium. SM exposure causes debilitating respiratory complications. This study was designed to evaluate clinical respiratory manifestations, and to compare chest X ray (CXR) and high resolution computed tomography (HRCT) scan of chest in SM exposed patients with respira...

Abstract The influence of the single polycarboxylate superplasticizer (PCE) and blending it mixed hydroxypropyl methylcellulose (HPMC) on hardening moulding quality surface pulverisation foam concrete was investigated. An orthogonal experimental design employed to determine optimum combination parameters for four property indexes (PIs) in this paper. A multi-index matrix analysis method used ev...

Settling-thickening tanks are used to achieve separation of the liquid and solid fractions of faecal sludge (FS). They were fi rst developed for primary wastewater treatment, and for clarifi cation following secondary wastewater treatment, and it is the same mechanism for solids-liquid separation as that employed in septic tanks. Settling-thickening tanks for FS treatment are rectangular tanks,...
