AIM To explore a method to obtain sub-millimeter data of the thin transverse section of the pterygopalatine fossa (PPF), and to study the thin transverse sectional anatomy of the adult pterygopalatine fossa and its communicating structure for providing anatomic gist for the imaging diagnosis and minimal invasive operation when PPF diseased. MATERIAL AND METHODS Two heads of adult cadaver with...

We calculate low scale gravity effects on the cross section for neutrino-nucleon scattering at center of mass energies up to the Greisen-Zatsepin-Kuzmin (GZK) scale, in the eikonal approximation. We compare the cases of an infinitely thin brane embedded in n = 5 compactified extra-dimensions, and of a brane with a physical tension MS = 1 TeV and MS = 10 TeV. The extra dimensional Planck scale M...

Detrital zircon U-Pb geochronology has enabled advances in the understanding of sediment provenance, transportation pathways, and depositional age sedimentary packages. However, sample selection processing can result biasing detrital spectra. This paper presents a novel approach using in-situ measurements on thin-sections to provide greater confidence maximum ages provenance interpretations. Ne...

By introducing a variable transformation ?=12(sin?+1), complex-form ordinary differential equation (ODE) for the small symmetrical deformation of an elastic torus is successfully transformed into well-known Heun’s ODE, whose exact solution obtained in terms functions. To overcome computational difficulties ODE dealing with boundary conditions, real-form system proposed. A general code numerical...

The Kirchhoff’s theory for thin, inextensible, elastic rods with nonhomogeneous cross section is studied. The Young’s and shear moduli of the rod are considered to vary radially, and it is shown that an analytical solution for the constitutive relations can be obtained for circular cross section and constant Poisson’s ratio. We comment on possible applications of our results.

Background: The radioactivity levels in sediment and rock samples of İkizdere and Kaptanpaşa Valley have been determined. To our knowledge, there seems to be no information about radioactivity level in the İkizdere and Kaptanpaşa Valley sediments and rocks so far. Materials and Methods: The average radium equivalent activity (Raeq), the total absorbed dose rate (D), the external risk index (Hex...
