The objective of the present study was to determine the 'stemness' characteristics of CD133+ cells (harvested from the squamous cell tongue carcinoma Tca-8113 cell line) in vitro and to observe the tumourigenicity of the CD133+ cells in the bodies of NOD/SCID mice. Single cells from the Tca-8113 cell line were observed for multiplication capacity in vitro. The suspending and pelletizing phenome...

The Swedish state-owned mining company LKAB has recently initiated the process of building a new pelletizing plant (MK3) in Malmberget, northern Sweden. The total expenditure will amount to €280 million and the new plant is expected to be operational around the turn of the year 2006-2007. Contractors are expected to employ a workforce of about 250 in connection with the construction of the plan...

Unlike flat sheets, crumpled paper balls have both high free volume and high compressive strength, and can tightly pack without significantly reducing the area of accessible surface. Such properties would be highly desirable for sheet-like materials such as graphene, since they tend to aggregate in solution and restack in the solid state, making their properties highly dependent on the material...

Improved methods for broiler chicken (Gallus gallus domesticus) litter utilization are needed to alleviate potential impacts of pollution around broiler production operations. Pelletization may constitute one improved method for handling broiler litter. The objective of this study was to determine the change in nutrient concentration from pelletizing broiler litter, and determine availability o...

This paper concerns the process of production and properties of pellets based on biomass wastes. Co-pelletization was performed for sewage sludge from municipal wastewater treatment plant and other biomass material such as animal and olive wastes. The aim of the present study was to identify the key factors affecting on the sewage sludge and agricultural residues co-pelletization processes cond...

In this article we present the findings from an extensive case study of the use of Virtual Reality (VR) models in large construction projects. The study includes two parts: The first part presents a quantitative questionnaire designed to investigate how VR models are experienced and assessed by the workforce at a building site. The second part includes a qualitative field survey of how VR model...

NOx, COx, and volatile organic compounds (VOCs) widely exist in motor vehicle exhaust, coke oven flue gas, sintering pelletizing gas. Potassium species have an excellent promotion effect on various catalytic reactions for the treatment of these pollutants. This work reviews effects potassium reaction processes, including adsorption, desorption, pathway selectivity reaction, recovery active cent...
