In oil industry, recovery of crude oil can be improved by injecting aqueous solutions containing surfactants, polymers, and mineral ions into an oil reservoir. This process is called enhanced oil recovery. Water and oil are immiscible, separated by an interface, and their motion through a capillary tube is governed by the surface tension. However, the physics can be more complex during an enhan...

OBJECTIVE A prospective epidemiological study was conducted at a fly-in-fly-out mining operation in Australia to assess the dynamics of occupational fatigue and its potential risk factors. METHODS Performance and perceived fatigue were measured at the start/finish of each 12-h shift throughout the 28-day roster (10 days day shift work on-site, 5 days rest off-site, 8 days night shift work on-...

Although the oetiological association between soot and cancer of the scrotum was recognized by Percival Pott as early as 1775, the role of mineral oils in the production of skin cancer was not recognized until considerably later. Joseph Bell of the Edinburgh Royal Infirmary reported a case of carcinoma of the scrotum in a Scottish shale oil worker in 1876. Southam and Wilson (1922) pointed out ...

Since the 1970s, concerns have been raised about elevated rates of mesothelioma in the vicinity of the taconite mines in the Mesabi Iron Range. However, insufficient quantitative exposure data have hampered investigations of the relationship between cumulative exposures to elongate mineral particles (EMP) in taconite dust and adverse health effects. Specifically, no research on exposure to taco...

Naturally occurring carbonated mineral waters have been known for a long time. These effervescent waters exist as a consequence of excess carbon dioxide in an aquifer dissolving under pressure. Although claims for the medicinal properties of these mineral waters have been grossly exaggerated, the presence of carbon dioxide does make aerated waters and soft drinks both more palatable and visuall...

Chickpea is a good source of high quality protein, carbohydrates, vitamins (thiamine and niacin), and minerals. However, its use in industry has been limited by variation in composition with cultivar and also the presence of oligosaccharides, trypsin inhibitors, phytic acids, tannin, and haemagglutinin. Different technologies have been studied to eliminate or minimise the undesirable factors in...

Organic compounds in wastewaters coming from textile and pharmaceutical industry generated multiple harmful effects on the environment and the human health. One of them is the methyl orange (MeO), an azoic dye considered to be a recalcitrant compound. The heterogeneous photocatalysis emerges as an alternative for treating this type of hazardous compounds, through the generation of OH radicals u...

The Mineral and Mining industry is a huge energy requiring sector which demands connections to viable electric power origin reference. With the upsurge of these mineral requests decreasing valued grades ores, aspiration approximated sky-rocket 36% by year 2035. It even projected accelerate geometrically from fact that sophistication powering mine locations speeds up stability into necessity app...
