The concept of a deformable body point is taken in the form of a continuum point and an elementary volume connected with it. The continuum point determines the spatial position of the deformable body point, and the elementary volume is the carrier of its material properties and stress-strain state characteristics.

This thesis aims to develop finite element models for studying vibration of the 2D-FGM beam. These models require high reliability, good convergence speed and be able to evaluate the influence of material parameters, geometric parameters as well as being able to simulate the effect of shear deformation on vibration characteristics and dynamic responses of the 2D-FGM beam.

Formation of new blood vessels is required for the growth and metastasis of all solid tumors. New blood vessels are established in tumors mainly through angiogenesis. Brain tumors in particular are highly angiogenic. Therefore, interventions designed to prevent angiogenesis may be effective at controlling brain tumors.

Truong Van Nam, Nguyen Xuan Dung, study the effect of substituents on the properties of aniline by approximate methods AM1 quantum ... Quantum mechanics is one of the fundamental theory of physics. Quantum mechanics is an extension and supplement of Newtonian mechanics (also known as classical mechanics). It is the basis of many other disciplines of physics and chemistry as solid state physics, chemistry quantum particle physics.
