The objective of this study is to carry out a parametric sensitivity analysis of PHAST atmospheric dispersion modelling for an accidental toxic gas release scenario. A methodology is developed and is applied to a nitric oxide gas dispersion scenario. We study the relative influence of uncertainty in independent input parameters (storage conditions, atmospheric variables, release parameters and ...

Introduction: Today, with development of various industries, the adverse events originated from explosion and emission of toxic and chemical substances have increased. These events may cause serious environmental problems that threaten human health and safety. Therefore, knowledge about the risk of toxic substances from industrial facilities is essential. Although, chlorine is extensively uti...

severe accidents of process industries in iran have increased significantly in recent decade. this study quantitatively analyzes the hazards of severe accidents imposed on people, equipment and building by a hydrogen production facility. a hazard identification method was applied. then a consequence simulation was carried out using phast 6.54 software package and at the end, consequence evaluat...

Little is known about the prevalence, functionality and ecological roles of temperate phages for members of the mycolic acid producing bacteria, the Mycolata. While many lytic phages infective for these organisms have been isolated, and assessed for their suitability for use as biological control agents of activated sludge foaming, no studies have investigated how temperate phages might be indu...

A two dimensional electrophoretic method is described for the routine clinical analysis of urinary proteins. Cellulose acetate electrophoresis is used for the first dimension, and SDS (sodium dodecyl sulphate) electrophoresis for the second dimension, the latter being performed together with gel staining (Coomassie Blue) on the „Phast System". The Separation media are supplied äs "ready-to-use"...
