Important science--it's all about the SPIN.

چکیده
The importance of a scientific finding can be difficult to ascertain because it requires both subjective judgment and foresight. We propose criteria, based upon whether a discovery is sizeable (S), practical (P), integrated (I), and new (N), that can be used individually or collectively to systematically assess the importance of a finding.

In this paper a simple model calculation of spin wave is given for the ferromagtic layer in ultra thin ferromagnetic/antiferromagnetic bilayer. In this model the magnetic layer is assumed as an isolated layer but the effect of antiferromagnetic layer on ferromagnetic layer and unidirectional anisotropy, is given in the effective field applied on each spin. The thin layer is assumed as two-dim...
متن کاملAn Entanglement Study of Superposition of Qutrit Spin-Coherent States
Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...
متن کاملNMR-the basic principles and its use in studies of water/ethanol/mixture
NMR is the one of the most widely used and helpful spectroscopic technicque. It's theoritical parts depend on quantum physics, this technique has transformed the practice of chemistry.It's principle based on spin angular momentum and NMR interactions in a static magnetic field. Proton shows two orientations named α and β. When spins pulsed, spins are changed from one orientation to another. Aft...
متن کاملEfficient Immobilised TiO2 in Polyvinylidene fluoride (PVDF) Membrane for Photocatalytic Degradation of Methylene Blue
Immobilised titanium dioxide (TiO2) in membrane structures has recently become attractive. This is due to the elimination of the separation step after the process of photocatalytic degradation. The efficiency of the TiO2 surface area exposed to UV light as the main important parameter needs to be considered. The immobilisation of TiO2 nanoparticles in the polyvinylidene fluoride (PVDF) membrane...

Background: Nowadays, many progresses have been occurred in medical science and transplantation process. Transplantation is now a life- saving standard treatment for some end stage diseases. Although the organs from brain death donors, are the best resource for cadaverous transplantation, there are many controversies among physicians about it's definition. The other important issue in trans...
