  • Soil mechanics involves a combination of engineering mechanics and the properties of soils. This description is broad and can encompass a wide range of soil types. These soils could either be saturated with water or have other fluids in the voids (e.g., air). The development of classical soil mechanics has led to an emphasis on particular types of soils. The common soil types are saturated sands, silts and clays, and dry sands. These materials have been the emphasis in soil mechanics textbooks.

  • High specific surface area. The amount of gas–liquid surface area per unit volume of material that is attainable in a foam is greater than that in comparable two-phase systems. This property makes gas–liquid foam particularly attractive for interphase mass transfer operations. Examples of such processes are froth flotation, in which valuable hydrophobic particles are recovered from a slurry, the recovery of oil sands, and the stripping of gases from effluent by absorption into the liquid phase....

  • The woman was still alive as unnatural thunder cracked across the sky. The lightning forked through the thrashing rain, stabbing at the desert sand. Rain splashed across the dunes, running down the bank towards the entrance of the tomb, washing over stone that had been parched for a thousand years. She was hardly more than a girl, her eyes betraying her fear as she shivered in the warm rain. The priests stood either side of her, holding her arms out from her body. Their heads were lowered - perhaps in shame, perhaps in an effort to keep them dry....

  • This work collects the recent papers discussed in the International Workshop on Debris Flows held in Kagoshima, Japan, in 1993, in response to the Inter- national Decade of Natural Disaster Reduction Program. Although the debris flow was called as a shadowy disaster about thirty years ago which often killed a few hundreds people, the recent studies are going to clarify the mechanism of the flow and ...

  • After allowing your wood piece to completely dry after staining, lightly spray Sanding Sealer, using back and forth movements. This application will ensure sealing the colour exactly the way you want it before the final application of lacquer or oil. It is important to move the spray can continuously while spraying or runs will occur! Keep the spray can in continual motion. Rather that one heavy coat, apply two lighter coats. (If sealer dries white, do not worry, the next lacquer step will correct it.) Once the sanding sealer is dry (5 – 10 minutes), use a very fine...
