INTRODUCTION: Craniocerebral trauma (CCT) is important problem of modern medicine and plays a dominant role in morbidity and mortality of the population. It is known the severity of CCT can be burdened by comorbid conditions, the degree of expression of which directly depends on age. AIM(S): The aim: to study the morphological features of the liver, kidneys and myocardium of mature and immature rats...
We discuss a class of orthogonal coordinates in E3 which are non-trivially R-separable for 3-dimensional Euclidean Helmholtz equation. The separation is both non-regular (in the sense of Kalnins and Miller) and non-Stäckel. One family of parametric surfaces consists of parallel Dupin cyclides, the other two consist of circular cones. These coordinates are used to simplify derivation of Friedlander's...
