A new computational method for the elastic interaction between dislocations and precipitates is developed and applied to the solution of problems involving dislocation cutting and looping around precipitates. Based on the superposition principle, the solution to the dislocation–precipitate interaction problem is obtained as the sum of two solutions: (1) a dislocation problem with image stresses...

Seventy-five consecutive patients aged 15 to 55 years with aneurysmal subarachnoid haemorrhage verified by CSF examination and cerebral angiography or at necropsy were studied. In 19 cases (25%; four women and 15 men) the bleeding was preceded within 24 hours by a bout of alcohol drinking. Alcohol-related cases composed 33% and 14% of the patients in the age groups 15-40 and 41-55 years, respec...

Several genetic and environmental factors appear to cooperate to precipitate type1 diabetes, a spontaneous autoimmune disease in humans and in the nonobese diabetic (NOD) mouse. NOD mice, like type1 diabetic patients, develop insulitis, an early infiltration of leukocytes into the pancreas that leads to inflammatory lesions within the islets. However, overt type1 diabetes requires the subsequen...

The dried park from Enantia chlorantha, was milled and solved into methanol overnight, separated the solute by decantation and repeat the previous process. The sediment was refused. The solute was concentrated and water was used to precipitate the proteins and they have discarded. After these procedures we have got at an alkaloid mixture, which according our GC/MS analysis had a palmatine basic...

This contribution deals with the numerical simulation of dislocation dynamics by means of parametric mean curvature flow. Dislocations are described as an evolving family of closed and open smooth curves driven by the normal velocity. The equation is solved using direct approach by semi-discrete scheme based on finite difference method. Numerical stability is improved by tangential redistributi...

Simulation of the Liesegang pattern formation in low concentration gradient is presented using concentration perturbation in a deterministic model. The precipitation process is based on ion-product supersaturation theory (Ostwald's model). In the classical experiments with high initial concentration gradients, appearance time and locations of the band formation are well reproducible. Decreasing...
