ELECTRICAL AND ELECTRONIC WASTE: A GROWING ISSUE

Obesity--a growing issue.

OBJECTIVES This article, based on longitudinal data, follows a sample of people who were aged 20 to 56 in 1994/95 to determine the percentage who made the transition from normal to overweight, or from overweight to obese by 2002/03. Characteristics that increased the chances of overweight people becoming obese are examined. DATA SOURCES The data are from five cycles of the National Population...

Electrical and Electronic Plastics Waste Co-Combustion with Municipal Solid Waste for Energy Recovery

Investigation of Reduction and Precipitation Rate of Colloidal Gold Particles Obtained in the Process of Electrical and Electronic Waste Recycling

This paper studies the influence of process parameters: temperature, the weight of the added precipitant agent, pH and reducing agent on the kinetics of the process of reduction and precipitation of gold of 98.44% purity obtained in the process of electrical and electronic waste recycling. The optimal conditions of reduction and precipitation of colloidal gold particles in the process of re...

A geological reconnaissance of electrical and electronic waste as a source for rare earth metals.

The mining of material resources requires knowledge about geogenic and anthropogenic deposits, in particular on the location of the deposits with the comparatively highest concentration of raw materials. In this study, we develop a framework that allows the establishment of analogies between geological and anthropogenic processes. These analogies were applied to three selected products containi...

Use of Palm Waste Cellulose as a Substitute for Common Growing Media in Aglaonema Growing

In order to evaluate the possibility use of palm waste cellulose as a substitute substrate for growing pot plants, an experiment was conducted in completely randomized block design with 6 replication and six treatments on Aglaonema sp. The treatments were 5 levels including 0, 25, 50, 75 and 100 palm celluloid wastes mixed with different rates of some amendments such as peat, coconut coir, perl...
