Previous studies point out a large (untapped) potential for energy efficiency in industry through the adoption of energy management practices. The aim of this paper is to describe and analyze energy management practices in two different Swedish energyintensive industries: the pulp and paper industry and the foundry industry. The results show that one third of the studied mills and about two fif...

Iron foundries have been identified as dioxin sources in previous field investigations. Similar formation mechanisms between dioxins and unintentional polychlorinated naphthalenes (PCNs) have led us to speculate that iron foundries are also potential PCN sources. In this study, PCNs in stack gas and fly ash samples representing atmospheric and residue emissions from 13 typical iron foundry plan...

Foundries and the Dawn of an Open IP Era T oday’s IC industry continues down a path of dis-integration it has followed for more than a decade—shifting from a vertical structure to a horizontal one, with many specialized and focused segments comprising the industry value chain. This dis-integration facilitates the growth of system-on-chip (SOC) technology and enhances operational efficiency by s...

BACKGROUND Iron and steel foundry workers are exposed to various toxic and carcinogenic substances including crystalline silica, polycyclic aromatic hydrocarbons, and arsenic. Studies have been conducted on lung cancer in iron and steel founding workers and the concentration of crystalline silica in foundries; however, the concentration of crystalline silica and cases of lung cancer in a single...

As the cost of manufacturing microprocessors continues to rise, chip makers have begun accelerating the export of fabrication capabilities to overseas locations. This trend may one day result in an adversarial relationship between system builders and chip producers. In this scenario the foundries may hide additional circuitry to not only compromise operation or leak keys, but also to enable sof...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...
