Many people believe that slabs on ground typically should have some reinforcing, but most slabs in North America are unreinforced concrete and perform well. If reinforcing is utilized, the amount that should be used depends on what is to be accomplished.
Micelles are lipid molecules that arrange themselves in a spherical form in aqueous solutions. The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic regions (polar head groups) as well as hydrophobic regions (the long hydrophobic chain). Micelles contain polar head groups that usually form the outside as the surface of micelles.
The monoglycerides that result from these splitting processes combine into a complex called a micelle. The micelle permits fat components to be soluble in water. Because bile salts have a hydrophobic, or water-repelling region, and a hydrophilic, or water-attracting region, the micelle is... ...attaches itself to water. When soap is placed in water, the hydrocarbon tails cluster together, while the polar heads adjoin the water.
