R. B. BULEY, AND JEAN LUMLEY Department of Anaesthetics, Royal Postgraduate Medical School, Ducane Road, London Many factors have been incriminated in the aetiology of the post-traumatic pulmonary insufficiency syndrome. One factor, which can possibly be avoided, is the deposition in pulmonary capillaries of cellular debris of microemboli following massive transfusion. Swank (1961) and McNamara...

The present study aims at investigation of the performance of nanofibrous filter, containing magnesium oxide (MgO) nanoparticles, for bioaerosols removal from the air stream. It synthesizes two types of polyacrylonitrile (PAN) and PAN/MgO nanofibers via electrospinning technique, and investigates the antibacterial properties of the produced nanofibers through disk diffusion. The air containing ...

background: water filtration units have been faced problems in water turbidity removal related to their media, which is determined by qualitative indices. moreover, current qualitative indices such as turbidity and escaping particle number could not precisely determine the efficiency of the media in water filtration, so defining new indices is essential. in this study, the efficiency of anthrac...

abstract background: inadequate dialysis is one of the main causes of mortality of the patients undergoing hemodialysis. the methods that lead to improvement of dialysis adequacy in these patients are of great importance due to them causing an improvement of quality of life. as numerous factors can play a role in improvement of dialysis adequacy, the present study aimed to investigate the level...

Separation of solids from fluid is a vital process to achieve the desired level of purification in industry. Contaminant filtration is a common process in a variety of applications in industry. Clogging of filter phenomena is the primary failure mode leading to replacement or cleansing of filter. Reduced performance and efficiency or cascading failures are the unfortunate outcomes of a clogged ...

Lignin is a valuable biomaterial. It is both naturally abundant and readily available as a byproduct of the pulping processes, and the proper reprocessing of lignin is an effective way to achieve waste recovery. Lignin fiber mats with web structures can be produced using electrospinning techniques. Such fiber mats are a promising material for use in the production of filter products. This study...

The purpose of these studies was to determine the capillary filtration coefficient of the small intestine of anesthetized dogs by the gravimetric technique. Capillary filtration was produced by elevating venous pressure. Filtration rate increased as venous pressure was increased but the relation between the two was not proportional. At venous pressures greater than 10 mm Hg, filtration rate ten...
