This seemingly opportunity for developing countries like Ghana which have mineral deposits comes with its accompanying repercussions. This paper looks at the general mining environment as a whole, narr...

Transmission electron microscopy analysis (TEMA) was used to analyze the bronchoalveolar lavage fluid (BALF) of 262 subjects occupationally exposed (OE) to nonfibrous mineral particles (NFMP) and 42 controls not occupationally exposed to mineral dusts. OE subjects were divided into three groups according to the lapse of time since last exposure: < or = 1 year and < 10 years (E2), > or = 10 year...

background: based on the economical and environmental concepts, the main purpose of the industrial waste management is reducing the production of these materials which is accessible by developing strategies of reuse, waste recycle and upgrading the technologies. accurate investigation of the quality and quantity of the industrial waste is the basis of the industrial waste correct management. th...

We investigate appearance standards in industry for gloss, haze, and goniochromatic color. Advantages of using appearance standards directly connected to physical reflection parameters include the small number of required measurements and the inexpensive commercially available instruments necessary to acquire the data. We review light reflection models recently developed for metallic and pearle...
