THIN ACCRETION DISKS AROUND MULTI-POLYTROPIC WORMHOLE

Thin accretion disks around multi-polytropic wormhole

In this paper, we study the physical properties of thin accretion disks in static and spherically symmetric multi-polytropic wormhole space-time.Using the Novikov-Thorne model, the electromagnetic flux, temperature gtech brush bar distribution, innermost stable circular orbits and radiative efficiency of thin disks are obtained.Comparing the result

Electronic Correlations, Jahn-Teller Distortions and Mott Transition to Superconductivity in Alkali-C60 Compounds

The discovery in 1991 of high temperature superconductivity (SC) in A3C60 compounds, where A is an alkali ion, has been rapidly ascribed to a BCS mechanism, in which the pairing is mediated by on ball optical phonon modes.While this has lead to consider that electronic correlations were not important in these compounds, further studies of various A

Maxillary mucocele-A missed out

Background: Maxillary sinus mucocele is a rare form of mucocele and are usually under diagnosed due to its vague symptomatic presentation.It is caused by obstruction of the natural ostium and accumulation of secretions inside the sinus cavities.It is a locally expansile lesion and symptoms are due to pressure on surrounding structures.Case Presenta
