Investigating the longitudinal optical conductivity of graphene systems, which is the mostimportant property for opto-electronic devices, for three-layer graphene systems theoretically and numerically is the main purpose of this study. Each layer can be mono- or bi-layer graphene. Separation between layers has been denoted by d, selected to be about ten nanometers. The carrier densities i...

This study aimed to obtain the absorbed dose distribution in a heterogeneous head simulator object where brain tumor of 2 cm diameter was located. Materials equivalent and were created. For simulation, elemental composition (H, C, N, O, others) mass density ρ respectively used. X-ray spectra 6, 10 18 MV used for exposures, projecting field 3×3 cm2 tumor, with an isocentric source distance 100 c...

We propose here a program of searches for degenerate electro-weakinos in various final state search topologies. In particular we emphasize the usefulness of searching for mass degenerate charginos and neutralinos in the mono-Z search channel. We demonstrate that the mono-Z search supercedes the mono-jet and mono-photon search topologies and present arguments using effective operators to explain...

mono-specific antisera against vibrio cholera ogawa nih-43 and vibrio cholera inaba 35-a3 were prepared from rabbit hyperimmune sera by absorbing against a heterologous strain. using ammonium sulphate precipitation procedure, gamma globulins were purified and concentrated. to visualize antigen-antibody reaction, gamma globulins were conjugated to staphylococcus aureus cowan-l (nctc: 8325) in th...

The 2-mono and 2,6-disubstituted methyl-1,4-dihydropyridines were synthesized by reaction of morpholine, thiophenol, 8-hydroxyquinoline, 2-naphthol and 2-mercopto-1-methyl imidazole with the 2-mono bromo and 2,6-dibromo-1,4-dihidropyridines.
