Aim Stripping is a technique of creating space for correction of crowding by interproximal enamel reduction. This study sought to assess the efficacy of mesial stripping of mandibu-lar deciduous canines for correction of rotated and lingually erupted lateral incisors. Materials and methods This clinical trial was performed on 42 patients with <3 mm mandibular anterior crowding. The required s...

The purpose of this article is to offer a f ramework for analysis and discussion of tour ism education. It first adopts a definition of tour ism within which interaction among its componen t s and ex t raneous aspects are considered. Speci...

Singular integral equation that has enormous applications in applied problems including fluid mechanics, biomechanics, electromagnetic theory and chemistry applications such as heat conduction, crystal growth and electrochemistry. An integral equation is called a singular integral equation if one or both limits of integration become infinite, or if the kernel of the equation becomes infinite at...

A Roman dominating function (RDF) on a graph G = (V,E) is a function f : V → {0, 1, 2} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 2. The weight of an RDF f is the value f(V (G)) = ∑ u∈V (G) f(u). A function f : V (G) → {0, 1, 2} with the ordered partition (V0, V1, V2) of V (G), where Vi = {v ∈ V (G) | f(v) = i} for i = 0...

In this study, we introduce a new familyof models for lifetime data called generalized extended Weibullpower series family of distributions by compoundinggeneralizedextended Weibull distributions and power series distributions. The compounding procedure follows the same setup carried out by Adamidis (1998). The proposed family contains all types of combinations between truncated discrete with g...

A Web portal is a gateway to the information and services on the Web, where its users can interchange and share information. In their brief lifetime, Web portals have benefited various sectors of the society and found widespread use (Jafari & Sheehan, 2003; Tatnall, 2005). By careful aggregation of information, Web portals simplify access, as well as decrease the time and effort of locating res...

Pancreatic cancer is one of the most common malignancies of the digestive system and, depending on the geographic area, fourth or fifth leading cause of cancer deaths (Lillemoe et al, 2000; Simon & Printz, 2001). Between 1960 and 1980, the incidence rates had increased significantly in most industrialised countries, including Poland. Corresponding 5-year survival rates demonstrated only slight ...

A set C of vertices in a graph G = (V,E) is total dominating in G if all vertices of V are adjacent to a vertex of C. Furthermore, if a total dominating set C in G has the additional property that for any distinct vertices u, v ∈ V \ C the subsets formed by the vertices of C respectively adjacent to u and v are different, then we say that C is a locating-total dominating set in G. Previously, l...

In this paper, we introduce and study a new class of multifunctions called faintly δ-β-continuous multifunctions in topological spaces.
