Several experiments investigated the theory that there is a tendency to interpret the axes of a large tilted frame of reference as surrogates of the main axes of the environment. Therefore there is a tendency to perceive such a frame as either upright or as less tilted thanit is--righting-- and, accordingly, to perceive a vertical rod as tilted in the opposite direction--the rod-and-frame effec...

OBJECTIVE To present a simplified classification of the deviated nose and the associated treatment outcome. DESIGN Retrospective analysis. SETTING Tertiary care rhinology clinic. PATIENTS Seventy-five individuals (49 males and 26 females) who underwent rhinoplasty for a deviated nose with minimum follow-up of 36 months. MAIN OUTCOME MEASURES Depending on the orientation of 2 horizontal ...

The adsorption behavior of a model additive, hexadecylamine, onto an iron surface from hexadecane oil has been characterized using polarized neutron reflectometry, sum-frequency generation spectroscopy, solution depletion isotherm, and X-ray photoelectron spectroscopy (XPS). The amine showed a strong affinity for the metal surface, forming a dense monolayer at relatively low concentrations; a l...

We present density functional theory calculations of methanol molecular adsorption at the (0001) surface of α-Al2O3, for methanol coverages of 1/4 to 1 monolayer (ML). Adsorption energies, adsorption-induced restructuring of the surface, and induced changes to the electronic structure are calculated. We find that methanol bonds with its O atom to Al atoms at the α-Al2O3(0001) surface with an ad...

Adsorption of environmentally important aromatic molecules on a water surface is studied by means of classical and ab initio molecular dynamics simulations and by reflection-absorption infrared spectroscopy. Both techniques show strong activity and orientational preference of these molecules at the surface. Benzene and naphthalene, which bind weakly to water surface with a significant contribut...

Reflectivity synthetic seismograms demonstrate that the type, layering and orientation of 1-D anisotropy influences strongly the coda of teleseismic P waves at periods T\1 sec, particularly P-SH converted waves. We assume the simplest form of anisotropy described by an elastic tensor with a symmetry axis ŵ of arbitrary orientation. The resulting phase velocities vary as cos 2j with respect to t...

We introduce a new class of algebras, which we call cluster-tilted. They are by definition the endomorphism algebras of tilting objects in a cluster category. We show that their representation theory is very close to the representation theory of hereditary algebras. As an application of this, we prove a generalised version of so-called APR-tilting.

We investigate the cluster-tilted algebras of finite representation type over an algebraically closed field. We give an explicit description of the relations for the quivers for finite representation type. As a consequence we show that a (basic) cluster-tilted algebra of finite type is uniquely determined by its quiver. Also some necessary conditions on the shapes of quivers of cluster-tilted a...
