Many studies have considered the effects of suspension properties on the dewatering process but fewhave focused on ore properties. Thus, the present work studied the effects of ore properties (density,particle size, mineralogy) on the dewatering process based on lab and pilot experiments. A hydrocyclonewas used to prepare the required samples for the experiments. To study the effects of mineral...

In this paper, the flow dynamics of polymer greases was investigated using micro-particle image velocimetry. Polymer have a different thickener structure, compared to widely used lithium-based greases, and they well-known ability release oil. How these properties affect grease deformation its is corresponding behavior lithium complex with same consistency. Two main tests were carried out, where...

Abstract The development of delivery systems providing prolonged release antitumor drugs represents one the challenges in designing and optimization novel tools for cancer therapy. employment spherical inorganic microparticles, particular, calcium carbonate vaterite microspheres, as microcarriers appears promising because their porous, matrix structure, biocompatibility, biodegradability. Here,...

In this research work, the parameters affecting the settling velocity within the thickeners were studied by introducing an equivalent shape factor. Several thickener feed samples of different densities including copper, lead and zinc, and coal were prepared. The settling tests were performed on the samples, and the corresponding settling curves were plotted. Using the linear regression analysis...

In the article, rheological properties of adhesive-binding systems used in production enterprises and newly developed polymer are studied. order to determine thermal stability systems, a analysis thickeners with different compositions was carried out. Mass loss observed heating curve thickener based on PAA, PVA Na-CMS. Endothermic effects during can be caused by physical phenomena such as lique...

This paper aims to design bio-based polyester as a viscosity modifier for lubricant properties. Bio-based polyricinoleate (PRic) and its saturated homologous polyhydroxystearate (PHS) have been synthesized from fatty acid methyl esters. The polycondensation performed in bulk one-step reaction without any purification leads two series of polyesters within large range molecular weights, with Mw b...

DOI: 10.5935/abc.20130137 Oropharyngeal dysphagia is a deglutition disorder resulting from neurological and/or structural impairment that may result in in decreased social interaction, loss of pleasure in food consumption, malnutrition, dehydration, infectious pulmonary processes and other high morbidity processes. Patients with heart disease from various causes present a risk of developing oro...
