Vibration dampers are installed on the machine foundations in order to reduce vibration level. Such technological solutions most expedient case of a harmonic load with low instability frequency. Unfortunately, do not provide such large reduction dynamic effect base, as isolation, but some cases their efficiency turns out be quite sufficient relatively simple implementation and manufacturing cos...

After the Law on Foundations was formed, every Foundation that existed before enactment of obliged to adjust its Articles Association with provisions Foundations. If not, there will be legal consequences for foundations have not made adjustments, or in other words, foundation legally weak and also an impact assets/wealth foundation. The purpose this study is find out implications new do comply ...

This paper presents a new finite modelling of the nonlinear static bending analysis piezoelectric functionally graded (FG) sandwich plates resting on elastic foundations. Finite element formulations are derived by using first-order shear deformation theory (FSDT) Mindlin and method. The proposed mathematical model this work verified comparing results with those other methods, they in good agree...

In the previous work, "Spin correlations in elastic $e^+ e^-$ scattering QED" (Yongram, 2018), spin for entangled electrons and positrons as emergent particles of electron-positron (also known Bhabha scattering) were calculated at tree level QED. When trying to reproduce author's we have found different results. this show calculation fully (initial final polarized states) partially (just probab...
