Analyzing material flow and value added associated with non-metallic mineral wastes in Japan

Manufacturing Firm Size Distribution in Iran Evidence from Food & Beverages and Non-Metallic Mineral Products

Empirical studies have shown that the size distribution of firms can be described as a lognormal or Pareto distribution. However, these studies have focused on developed countries and little attention has been devoted to developing countries. Using the variable of number of employees as a measure of firm size, this paper investigates the shape of firm size distribution in the food & beverages i...

Converting non-metallic printed circuit boards waste into a value added product

The aim of this study was to investigate the feasibility of using nonmetallic printed circuit board (PCB) waste as filler in recycled HDPE (rHDPE) in production of rHDPE/PCB composites. Maleic anhydride modified linear low-density polyethylene (MAPE) was used as compatibilizer. In particular, the effects of nonmetallic PCB and MAPE on mechanical properties of the composites were assessed throug...

Dynamic lymphoscintigraphy in breast cancer patients: feasibility and added value

Introduction: Lymphoscintigraphy is imaging of the lymphatic system and has been integrated into the sentinel node mapping procedures. Lymphoscintigraphy usually encompasses early or delayed static images. However, immediate dynamic imaging of the lymphatic basins and tumors has also been used as an adjunct lymphoscintigraphy imaging. The aim of this study was ...
