Multiple vertebral compression fractures occurred in a pregnant woman receiving heparin over nine months. This phenomenon may be more common than is clinically recognised and warrants careful re-examination of the indications and method of administration of anti-coagulants during pregnancy.

Affinity chromatography of human cryosupernatants on anti-human factor VIII-Sepharose yielded a plasma devoid of detectable factor VIIIC, VIIIR:Ag, and VIIIR:WF activities. This plasma was indistinguishable from severe congenital hemophilic plasma when used as substrate in factor VIII coagulant assays.

Background & Aims of the Study: The wastewater created as a result of stone cutting industries enters some pools for re-consumption so that its suspended solids settle by gravity. By taking to account the high volume of water and sludge, treatment of wastewater and removal of sludge cause many problems for stone cutting units. The objective of this study was to determine the quality of wast...

This study applied a filter press for dewatering that uses pressure to reduce the water content of sludge generated in sewage treatment plants and evaluated improvement dewaterability under various coagulation conditions according type coagulants, amounts, pH conditions. The was by measurement time (TTF), change zeta potential, cake after dewatering. It found conditions, inorganic coagulants we...

Pollution in river water affects human, plant and animal health activities, its removal using chemical coagulants is a huge concern. This study aims to reduce turbidity COD pollutants through coagulation-adsorption process by Tacca leontopetaloides biopolymer flocculant (TBPF) powder activated carbon (PAC). In coagulation experiment, TBPF dosages were varied evaluate the effect on Bioblock floc...

Phosphorus is an essential nutrient for all living organisms. However, high concentrations in a water body accelerates eutrophication. Discharge limits for phosphorus are getting tighter for wastewater treatment plants, thus new tertiary treatments for removal have to be considered. In addition, hygienization of wastewater may become mandatory. At Viikinmäki wastewater treatment plant, the phos...

Introduction: The most important environmental problem of automotive industries is the produced wastewater due to its various processes. The flocculation and coagulation along with chemical sequestration are among important processes for removing contaminants from wastewaters. The aim of this study is to investigate the efficiency of coagulation and flocculation process along with chemical sequ...

Water treatment (WT) is currently among the major areas of research due to depletion water resources and fearmongering regarding environmental pollution, which has compelled upgrading conventional WT technology towards recycling reuse. This review aims provide current state natural coagulants their application in purification surface as sufficient clean required for household needs, health secu...

colloids are small suspended particles in water which can not be settled or removed naturally due to their light weight and stability. these particles pose some degree of stability and cause water turbidity. there are some concerns regarding colloid removal efficiency in water treatment plants of iran. in this study, the effectiveness of aluminium sulfate and poly-aluminum chloride was evaluate...
