Waves form when the water surface is disturbed, for example, by wind or gravitational forces. During such disturbances energy and momentum are transferred to the water mass and sea-state is changed. For shallow water regions, the bottom topography affects the waves dramatically. Waves may cause evident slant of the ocean surface with large inclination angle of about 55 o . When high-speed rigid...

Event-driven molecular dynamics simulations are carried out on two rigid-body systems which differ in the symmetry of their molecular mass distributions. First, simulations of methane in which the molecules interact via discontinuous potentials are compared with simulations in which the molecules interact through standard continuous Lennard-Jones potentials. It is shown that under similar condi...

To investigate the translation of a compound particle in a highly viscous, incompressible fluid, we carry out an analytic study on flow past a fixed spherical compound particle. The spherical object is considered to have a rigid kernel covered with a fluid coating. The fluid within the coating has a different viscosity from that of the surrounding fluid and is immiscible with the surrounding fl...

Let us remind that Sommerfeld model of charged rigid sphere [1] (Sommerfeld particle) is the simplest theoretical model to take into consideration the ”back-reaction” of self-electromagnetic field on equation of motion of a radiating extended charged body (for point-like charge we have the known LorentzDirac equation with all its problems: renormalization of mass, preacceleration, runaway solut...

This case report describes an 11-year-old boy with a known esophageal bezoar admitted to surgery for esophagogas-troduodenoscopy with biopsy and possible removal of the bezoar. On induction, a copious amount of fluid and solid food particulate was noted in the posterior oropharynx, interfering with immediate intubation. After clearing of the oropharynx, the patient was intubated. A bronchoscopy...

In this work we consider the Suslov problem, which consists of a rotation motion of a rigid body, whose center of mass is located at one axis of inertia, around a fixed point O in a constant gravity field restricted to a nonholonomic constraint. The integrability and non-integrability has been established by a number of authors for the nongeneric values of b = (b1, b2, b3) which is the unit vec...
