Successful orthodontic treatment is based on a clear perception by the clinician of a patient's facial preference and treatment needs. Bimaxillary protrusion is a normal facial trait seen in the Black population and the most acceptable bimaxillary facial profile in a sample of Black subjects was determined by Beukes et al in 2007. Variations from this ideal profile may require extractions as pa...

Reading "'Ideal Theory' as Ideology," I found the distinction Mills makes between ideal-asidealized-model and ideal-as-descriptive-model to be very close to the distinction often found in Marxist political economy and philosophy between mental generalizations/idealizations and real abstractions, respectively--though this is a debate I've always had difficulty with. So, as I understand it, if bo...

Memristors have pinched hysteresis loops in the V − I plane. Ideal memristors are everywhere non-linear, cross at zero and are rotationally symmetric. In this paper we extend memristor theory to produce different types of non-ideality and find that: including a background current (such as an ionic current) moves the crossing point away from zero; including a degradation resistance (that increas...

We study the initial ideal of binomial edge ideal in degree 2 ([in<(JG)]2), associated to a graph G. We computed dimension, depth, Castelnuovo-Mumford regularity, Hilbert function and Betti numbers of [in<(JG)]2 for some classes of graphs. AMS Mathematics Subject Classification (2010): 05E40, 16E30

We prove the uniqueness of chemical equilibrium for an ideal mixture of ideal gases in a closed, spatially homogeneous volume. Uniqueness, a fundamental issue of chemical physics, is incompletely justified in textbooks and much of the scientific literature. We first reproduce a little known proof by Zel’dovich and show in a more direct fashion than originally presented that a unique equilibrium...

In Yoshida [11], a method to find ideal points and boundary slopes from an ideal triangulation was introduced. But the method only gives a necessary condition which the valuation corresponding to an ideal point satisfies. We give a simple sufficient condition for the existence of the corresponding ideal points.

in this paper, for a complete lattice l, we introduce interval-valued l-fuzzy ideal (prime ideal) of a near-ring which is an extended notion of fuzzy ideal (prime ideal) of a near-ring. some characterization and properties are discussed.

This theoretical study shows the technical feasibility of self-powered geothermal desalination of groundwater sources at <100 °C. A general method and framework are developed and then applied to specific case studies. First, the analysis considers an ideal limit to performance based on exergy analysis using generalised idealised assumptions. This thermodynamic limit applies to any type of proce...
