Parajulee and Wania (1) make an important contribution to understanding the origin and magnitude of pollution caused by the massive oil sands industry in northeastern Alberta. Until recently, the oil sands industry and government officials have claimed that all pollutants carried by the lower Athabasca River system were the result of soil erosion, forest fires, and other natural phenomena. This...

Extraction of oil from Canadian tar sands is becoming increasingly contentious as it is claimed the process is one of the highest in terms of greenhouse gas emissions. But now, along with environmental campaigners, some shareholders in the companies that mine and fund tar sand oil are beginning to protest at the activity. British companies spearheading the drive to exploit the Canadian tar sand...

Both calcium-containing and noncalcium-containing phosphate binders can increase gastrointestinal calcium absorption. Previously, we observed that lanthanum carbonate administration to rats with renal failure is not associated with increased calciuria. Additionally, lanthanum carbonate treatment in dialysis patients has been associated with a less pronounced initial decrease in serum parathyroi...

The Euphrates River is considered a famous one among the rivers in world. current study an attempt to give information about bed sediments from Hilla Shatt Al-Arab at Basrah, through sedimentological investigations. Forty-two samples were subjected grain size analysis, representing twelve core sampling sites. sand fractions (fine-very fine) decrease Basrah cities, beside interval depths top bot...

Focused fluid flow shapes the evolution of marine sedimentary basins by transferring fluids and pressure across geological formations. Vertical conduits may form where localized overpressure breaches a cap rock (permeability barrier) thereby transports overpressured towards shallower reservoirs or surface. Field outcrops an Eocene system at Pobiti Kamani Beloslav Quarry (ca 15 km west Varna, Bu...

Loose sands (siliceous, silty, and calcareous classes) are extensively found near arid areas in Egypt. Furthermore, many geotechnical structures, like water channels roads, may be constructed on weak or loose sand soils. The behavior of is usually connected with different interdependent problems, such as high permeability, low shear strength, bearing capacity, seepage, stability. This work char...

Introduction Each June, Wimbledon Centre Court becomes the focal point for the performances of the world’s leading tennis players. Matches showcase pure theatre—the drama, the sweat, the joy and tears, not to mention the physique of the players and the contortions of their bodies as they move around the court. In 2011, Bethanie Mattek-Sands arrived on court at Wimbledon in a costume designed by...

M. Łucarz, AGH University of Science of Technology, Engineering of Faculty Foundry, Kraków, Poland The paper presents the results of the research on the used moulding sands subjected to mechanical and thermal reclamation at different stages of the process in the foundry. The research on thermal treatment was carried out in an experimental thermal reclamation appliance. The effects of the proces...
