For the elderly especially, temperature sensors and water flow detectors should also be installed to indicate over or under temperature or the presence of water leaks.
The primary difference between bitumen and ordinary crude is the size of the hydrocarbon molecules: in liquid oil, these molecules contain between five and twenty carbon atoms, while in bitumen they contain more than twenty. (At room temperature, pure bitumen is so viscous that it will not flow.) The main job of the upgrader is to break down the oversized hydrocarbons into smaller units.
While earthquakes have often been blamed for rock failures and landslides on mountain slopes, scientists also point at global temperature rises for rapid thawing of snowfields and glacial melt that can disturb the flow of snow-fed rivers.
