Our object is to give an overview of some basic results about holomorphic mappings of circular domains in various spaces of operators. We begin by considering C*-algebras and pass to J*-algebras and other spaces when this seems natural. Our first result is a simple extension of the maximum principle where the unitary operators play the role of the unit circle. We illustrate the power of this re...

Liquid crystal (LC) provides a suitable platform to exploit structural motions of molecules in a condensed phase. Amplification of the structural changes enables a variety of technologies not only in LC displays but also in other applications. Until very recently, however, a practical use of LCs for removable adhesives has not been explored, although a spontaneous disorganization of LC material...

in this paper, the effects of input temperature and compression ratio on the net output work and efficiency of the air standard cycles, i.e. atkinson cycle, diesel cycle and otto cycle are analyzed. we assumed that the compression and power processes are adiabatic and reversible and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ...

the present report describes orthodontic treatment of a patient with skeletal class iii malocclusion and maxillary hypoplasia. to correct the retrusive maxilla, the treatment plan included an intra-oral removable device. it had the advantages of good patient cooperation, ease of construction and effective modification. forward growth of the maxilla, minimal downward and backward rotation of the...

background and aims. the first few days following the insertion of complete dentures are critical for the patients since they are struggling to adapt to their new dentures. this study aimed to evaluate the most common locations of traumatic ulcerations, their frequency and also the duration and number of adjustment visits required to achieve patient comfort following placement of complete dentu...

For a brick apart from a few small graphs, Lovász (1987) proposed a conjecture on the existence of an edge whose deletion results in a graph with only one brick in its tight cut decomposition. Carvalho, Lucchesi, and Murty (2002) confirmed this conjecture by showing the existence of such two edges. This paper generalizes the result obtained by Carvalho et al. to the case of irreducible near-bri...

Abstract. Let x0 ∈ Ω ⊂ R, n ≥ 2, be a domain and let m ≥ 2. We will prove that a solution u of the polyharmonic equation ∆u = 0 in Ω \ {x0} has a removable singularity at x0 if and only if |∆u(x)| = o(|x − x0|) ∀k = 0, 1, 2, . . . , m − 1 as |x − x0| → 0 for n ≥ 3 and = o(log(|x−x0|)) ∀k = 0, 1, 2, . . . , m− 1 as |x−x0| → 0 for n = 2. For m ≥ 2 we will also prove that u has a removable singula...

High-quality esthetic veneers can be produced in a single treatment session only by means of chairside CAD/CAM technology. With efficient therapy, the duration of the relatively long treatment cycle can be optimized: planning casts and a diagnostic wax-up are steps that simplify therapy decisions, the same as with veneers produced by laboratories. After production of a mock-up and preparation o...
