In December 2002, the Oil & Gas Journal reported that, holding 15% of the world's proven crude oil reserves, Canada ranks as number two in the world – after Saudi Arabia – with Alberta's oil sands accounting for the bulk of the country's store. As more projects come onstream, oil sands production is projected to make up about two thirds of …

Structural features of sand making machine: 1. The main shaft assembly of the sand making machine is installed in the middle of the square prism. It transmits power from the motor through the V-belt and keeps the impeller rotating. 2. The impeller is installed on the shaft head at the upper end of the main shaft assembly.

And nowhere does that ring more true than in the construction industry. Windows, concrete, stone floors – all of these are largely made up of sand. Reinforced concrete, often used in construction is made up of one third cement and two thirds sand. For a medium-sized house that means approximately 200 tons of sand is needed.

Artificial Bee Colony (ABC) algorithm is a popular metaheuristic due to its simplicity yet a stronger search mechanism. However, some researchers have reported that ABC algorithm lays more emphasis on exploration in comparison with exploitation, its performance also deteriorates gradually as the dimensions of the problems increase and …

The problem is that oil sands producers use more water a year than the city of Calgary and its 1.3 million inhabitants. And water consumption is linked to CO2 emissions. If less water was used in the refining process, less gas would be required to heat it. Researcher Nicholas Beyer has taken it upon himself to address this problem.

For example, in 2014 the USA exported about US$450 million worth of sand to other countries. Exports minus Imports is a component of aggregate demand (AD) and therefore the exporting of sand increases exports which increases AD. This increase in AD caused by increasing sand exports is depicted on Figure 4.
