INTRODUCTION Our objective was to determine whether dental esthetics have any influence on finding a new job. METHODS Ten patients with orthodontic treatment needs for various types of malocclusions were selected. Smiling facial photographs of all patients were obtained and digitally altered (orthodontic correction of teeth). After the images were obtained, 2 different questionnaires were pre...

Rayleigh-Taylor mixing is a classical hydrodynamic instability that occurs when a light fluid pushes against a heavy fluid. The two main sources of nonideal behavior in Rayleigh-Taylor (RT) mixing are regularizations (physical and numerical), which produce deviations from a pure Euler equation, scale invariant formulation, and nonideal (i.e., experimental) initial conditions. The Kolmogorov the...

Infrared reflection-absorption spectroscopy (IRRAS) in combination with isotopic substitution and a modified 2D IR correlation analysis procedure were used to study the dynamics of phospholipid acyl chain structure in both an ideal and a nonideal binary monolayer mixture spread at the air-water (A/W) interface. The ideal mixture consisted of a 1:2 molar ratio of 1,2-dipalmitoyl-sn-glycero-3-pho...

Abstract We consider the solution of subset sum problem based on a parallel computer consisting self-propelled biological agents moving in nanostructured network that encodes computing task its geometry. develop an approximate analytical method to analyze effects small errors nonideal junctions composing by using Gaussian confidence interval approximation multinomial distribution. concretely ev...

Proper evaluation of the Gibbs free energy and other properties of seawater and other aqueous solutions is essential in the analysis of desalination systems. Standard seawater has been studied extensively and property data are readily accessible. However, many aqueous solutions requiring desalination have significantly different composition from seawater and seawater data is generally not accur...

On the basis of a quantum-statistical approach to the electrical conductivity of nonideal plasmas we derive analytical results in the classical low-density regime, in the degenerate Born limit, and for the contribution of the Debye-Onsager relaxation effect. These explicit results are used to construct an improved interpolation formula of the electrical conductivity valid in a wide range of tem...

This paper describes a backtracking algorithm for the enumeration of nonisomorphic minimally nonideal (n × n) matrices that are not degenerate projective planes. The application of this algorithm for n ≤ 12 yielded 20 such matrices, adding 5 matrices to the 15 previously known. For greater dimensions, n = 14 and n = 17, 13 new matrices are given. For nonsquare matrices, 38 new minimally nonidea...

We consider a parabolic problem with Robin boundary condition which arises when the edge of micro-electro-mechanical-system (MEMS) device is connected flexible nonideal support. Then via rigorous analysis we investigate structure solution set corresponding steady-state problem. show that critical value (the pull-in voltage) exists so system has exactly two stationary solutions applied voltage l...

In this paper, the effect of antenna sectorization in the reverse link Erlang capacity of a multiclass code-division multiple-access (CDMA) cellular system is studied. Traditionally, it has been considered that the capacity is multiplied by a factor equal to the number of sectors introduced. This is true only in the ideal antenna sectored system. However, due to the nonideal antenna radiation p...
