In studying lines in the plane, when we needed to describe how a line was tilting, we used the notions of slope and angle of inclination. In space, we want a way to describe how a plane is tilting. We accomplish this by multiplying two vectors in the plane together to get a third vector perpendicular to the plane. The direction of this third vector tells us the “inclination” of the plane. The p...

background and aims. orientation of the occlusal plane is one of the most important clinical procedures in prosthodontic rehabilitation of edentulous patients. the aim of this study was to define the best posterior reference point of ala-tragus line for orientation of occlusal plane for complete denture fabrication. materials and methods. fifty-three dental students (27 females and 26 males) wi...

in an axisymmetric co2-n2-h2o gas dynamic laser, let ? denote the intersection of the vertical plane of symmetry with the upper part of the (supersonic) nozzle. to obtain a maximal small signal gain, some authors have tested several families of curves for ?. to find the most general solution for ?, an application of pontryagin’s principle led to the conjuncture that the optimal ? must consist o...

We report inelastic neutron scattering measurements at excitation energies h̄v , 41 meV in YBa 2Cu 3O 7. We separate magnetic and phonon contributions to the scattering cross section by a detailed analysis of the momentum dependence of the scattered intensity. The previously reported broad peak around q ­ spya, pyad in the normal state can be entirely accounted for by a phonon which primarily in...

In the present work, the free vibration behavior of rectangular graphene sheet under shear in-plane load is studied. Nonlocal elasticity theory has been implemented to study the vibration analysis of orthotropic single-layered graphene sheets (SLGSs) subjected to shear in-plane load. The SLGSs is embedded on a viscoelastic medium which is simulated as a Visco-Pasternak foundation. Using the pri...

We propose a new method of detecting supersymmetry at LEP2 and the NLC when R-parity is violated by an LLĒ operator. We consider the processes eγ → ν̃jek and eγ → l̃kν̄j which can test seven of the nine LLĒ-operators. A Monte-Carlo analysis is performed to investigate the sensitivity to the sneutrino signal, and the 5σ discovery contours in the mν̃j vs. λ plane are presented. For an integrated lumi...

The sarcoplasmic reticulum (SR) of striated muscle has an intricate geometry that makes anatomical analysis difficult ; even in fortunate en face views, tubules of the SR pass in and out of the plane of sectioning and, because of the thickness of the section, morphological details of the SR are often obscured by the inevitable superimposition of adjacent myofibrils and other cellular components...

We consider photoemision from a two-electron quantum dot and find analytic expression for the cross-section. We show that the emission cross-section from the ground state as a function of the magnetic field has sharp discontinuities corresponding to the singlet-triplet transitions for low magnetic fields and the transitions between magic numbers (2J+1) for high magnetic field. We also find the ...
