As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...

In this work, we present an updated study about the interactions of quarkonia with surrounding hadronic medium. The meson-meson are described a chiral effective Lagrangian within framework unitarized coupled channel amplitudes. particular, extend previous work performed in charmonium sector by calculating cross-sections for $\Upsilon$ scattering light pseudoscalar mesons ($\pi, K, \eta$) and ve...

An 8-node quadrilateral plane element US-QUAD8 is developed for linear isotropic hardening material in the framework of updated Lagrangian unsymmetric finite formulation where B L matrix constructed by classical shape function, and R higher-order basis function global coordinate system. The present eliminates influence Jacobian elemental stiffness guarantees quadratic completeness displacement ...

the built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. the built up layer (bul) is formed in second deformation zone near the tool-chip interface in the back of the chip. this parameter influences the tool life and machined surface quality. this bul should not be confused with the built up edge (bue). the deformation of the bul in...

In this paper we study isotropic Lagrangian submanifolds , in complex space forms . It is shown that they are either totally geodesic or minimal in the complex projective space , if . When , they are either totally geodesic or minimal in . We also give a classification of semi-parallel Lagrangian H-umbilical submanifolds.
