In this work was investigated the feasibility to use Waste Electrical and Electronic Equipment (WEEE) glasses in construction sector as secondary raw material. WEEE glasses were used in different percentages as a function of the product obtained: 30-40wt% for glaze formulations, about 40wt% for glass-ceramics and 5wt% in brick bodies. The laboratory and industrial scale up results demonstrated ...

The Internet’s large-scale global penetration has spawned an increasingly large number of technologyand Web-savvy consumers, creating a huge opportunity for both industrial manufacturers and their end customers. Over the past decade, e-commerce has evolved from a basic communication and transaction channel between buyer and seller, to an end-to-end collaboration medium between all stakeholders....

Petroleum coke is processed into calcined coke in a rotary kiln, where the temperature profiles of flue gas and coke bed are highly nonuniform due to different flow and combustion mechanisms. Motivated by saving energy costs, the effect of refractory brick's thermal properties on potential energy savings is investigated. This study focuses on investigating potential energy savings by replacing ...

A large quantity of sludge is generated each year from water treatment plants in Egypt. Disposing the sludge to the nearest water stream is the common practice in Egypt, which accumulatively rise the aluminum concentrations in water and consequently in human bodies. This practice has been linked to occurrence of Alzheimer’s disease. Landfill disposal of the sludge is impractical because of the ...

Background Manual brick-manufacturing units in India engage a large number of female workers on a daily-wage basis for a period of 8 months per year. There are two groups of female workers in the brickfields: the brick molders and the brick carriers. These brickfields are mostly unorganized, and the workers are exposed to extreme conditions such as very high seasonal heat. The present trend of ...

Brick and Mortar Chip Fabrication Martha Allen Kim Chair of the Supervisory Committee: Professor Mark Oskin Computer Science and Engineering While Moore’s Law has advanced the semiconductor and technology industries, it has simultaneously driven up the cost of engineering a chip in a modern silicon process. The result is that fewer and fewer chips are produced in larger and larger volumes, stif...
