The impact behavior between the charge and lifter has significant effect to address the mill processing, and is affected by various factors including mill speed, mill filling, lifter height and media shape. To investigate the multi-body impact load behavior, a series of experiments and Discrete Element Method (DEM) simulations were performed on a laboratory-scale mill, in order to improve the g...

Different techniques were compared for their effectiveness in the disruption of the rigid cell walls of Basidiomycetes. Grinding under liquid nitrogen, stirred glass bead milling and enzymatic cell lysis were applied to the mycelia of Pleurotus sapidus and Lepista irina grown submerged. Each of the disruption procedures was evaluated by testing the quantity and quality of released intracellular...

The ability to culture hematopoietic cells in readily characterizable and scalable stirred systems, combined with the capability to utilize serum-free medium, will aid the development of clinically attractive bioreactor systems for transplantation therapies. We thus examined the proliferation and differentiation characteristics of peripheral blood (PB) mononuclear cells (MNC), cord blood (CB) M...

On the morning of 25 March 1980, there was unusual activity at Glasgow airport's Customs. A parcel containing a bottle of the most valuable drug in the world, interferon, had just arrived from Denmark. Hailed as a possible cure for cancer, interferon was intended for the experimental treatment of two young patients with advanced cancer at the Royal Hospital for Sick Children in Glasgow.' The ev...

This study presents a simple but effective process route for the production of transparent coatings on glass substrates from inorganic pigment goethite. For this purpose, coating suspensions were prepared by wet milling with stirred media mill. A water/ethanol mixture was used as liquid medium to take advantage resulting low surface tension process. In manner, stable particles down 50 nm in siz...

This paper examines the design of comminution circuits and the issues that impact on comminution circuit efficiency. Circuit efficiency is discussed, principally from the perspective of power efficiency. However, operating efficiency, maintenance efficiency, capital expenditure and return on investment are often the key efficiency factors in project development outweighing power efficiency cons...
