temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. surgery is the only treatment. this study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. ...

Experimentation has been carried out to find the influence of a gap provided in ribs on thermohydraulic performance of a square duct roughened with discrete inclined ribs. The two opposite walls of the square duct are roughened with ribs having attack angle (α) of 45 and a gap on its length. The investigation has been performed for relative roughness pitch (p/e) of 10, relative roughness height...

In a recent Letter [1] Öğüt, Chelikowsky, and Louie (OCL) calculated the optical gap of Si nanocrystals as ε g,OCL = ε qp g,LDA − E e−h Coul, where ε qp g,LDA is the quasi-particle gap in the local-density approximation (LDA) and E Coul is the electron-hole Coulomb energy. They argued that their method produces different results from conventional approaches (e.g. pseudopotential [2]). We show i...

Abstract. Band structure and optical properties of defectChalcopyrite type semiconductor ZnIn2Te4 have been studied by TB-LMTO first principle technique. The optical absorption calculation suggest that ZnIn2Te4 is a direct-gap semiconductor having a band gap of 1.40 eV., which confirms the experimentally measured value. The calculated complex dielectric-function ǫ(E) = ǫ1(E)+ iǫ2(E) reveal dist...

Photoproduction events which have two or more jets with transverse energy E T > 4:5 GeV have been studied in the p centre of mass energy range 158 GeV < W < 247 GeV with the H1 detector at HERA. The fraction f (() of events with a rapidity gap between the two highest E T jets is measured as a function of the rapidity separation between the jet axes. A gap is deened as the absence between the je...

Data from the H1 detector at HERA have been used to study photoproduction events which have two or more jets. The data were taken in 1996 and correspond to an integrated luminosity of 6.63 pb−1. Events were studied in the photon-proton centre of mass energy range 165 GeV < W < 243 GeV and with Q < 0.01 GeV. Jets were defined using the longitudinally invariant kt algorithm. Events selected had o...

We describe a new version of the elliptic curve encryption schemes PSEC (Provably Secure Elliptic Curve). PSEC{3 is a public-key encryption system that uses the elliptic curve El Gamal trapdoor function and two random functions (hash functions) as well as any semantically secure symmetric encryption scheme, such as the one-time pad, or any classical block-cipher. Furthermore, we de ne a new pro...

Th ree contemporary leadership challenges face local governments today. Th e fi rst encourages department heads to more actively work the intersection between political and administrative arenas. Th e second promotes collaborative work, synchronizing city and county boundaries with problems that have no jurisdictional homes. Th e third argues that citizen engagement is no longer optional—it is ...
