The general Meshless Local Petrov-Galerkin (MLPG) type weak-forms of the displacement & traction boundary integral equations are presented, for solids undergoing small deformations. Using the directly derived non-hyper singular integral equations for displacement gradients, simple and straight-forward derivations of weakly singular traction BIE's for solids undergoing small deformations are als...

Chitosan, a cationic carbohydrate polymer manufactured from chitin in shrimp and crab wastes, coagulated suspended solids in cheese whey as effectively or more so than ten commercial synthetic polymers. Concentrations of suspended solids after settling were reduced over 90% by coagulation at pH 6.0 with a ratio of chitosan to suspended solids of 2.15% (1:46.5). The yield of coagulated solids wa...

Nonaffine deformations of amorphous nanostructures have been studied within the framework a random matrix model. Near boundary between and crystalline solids, nonaffine solids lead to formation region with altered effective elastic properties. It is shown that thickness has same order magnitude as scale non-affine deformations. Keywords: deformations, bodies, matrices.
