The width of the cusp region is an indicator of the strength of the merging process and the degree of opening of the magnetosphere. During three years, the Magion-4 satellite, as part of the Interball project, has collected a unique data set of cusp-like plasma observations in middle and high altitudes. For a comparison of highand low-altitude cusp determination, we map our observations of cusp...

Aim: the aim of this study was to compare cusp deflection, infraction and fracture in teeth filled with three temporary filling materials. Materials & method: Forty five extracted human premolar teeth were chosen. After root canal therapy and mesio-occluso-distal cavity preparation, samples were randomly divided into three groups , each contained 15 teeth and filled with three temporary filling...

The magnetospheric cusp is a funnel-shaped region where shocked solar wind plasma is able to enter the high-latitude magnetosphere via the process of magnetic reconnection. The plasma observations include various cusp signatures such as ion energy dispersions and diamagnetic effects. We present an overview analysis of cusp plasma observations at the Saturnian magnetosphere from the Cassini spac...

The talon cusp is a relatively rare dental developmental anomaly characterized by cusp-like projections, usually observed on the lingual surface of the affected tooth. Normal enamel covers the cusp and fuses with the lingual aspect of the tooth. The cusp may or may not contain an extension of the pulp. The condition can occur in both the primary and permanent dentitions. However, the occurrence...

background and aims. the present study evaluated the most common reasons for replacing amalgam restorations in a university clinic. materials and methods. a total of 217 restorations which needed to be replaced were clinically and radiographically evaluated in a period of 4 months. the frequencies of reasons for replacing amalgam restorations were calculated: the assessed items included recurre...

dental anomalies are rare findings that may affect development of occlusion and early intervention may be required. here, a case of multiple anomalies in primary and perma nent dentitions is reported. the patient referred to the dental center with the chief complaint of multiple tooth decay. in the oral examination, the rare case of triplica tion between the right geminated man-dibular a and ri...

background: talon cusp is a rare dental anomaly characterized by a cusp‑like projection, often including the palatal surface of the affected tooth. the aim of the present study was to investigate the prevalence and characteristics of talon cusps in a group of turkish children. materials and methods: the study population consisted of 14,400 subjects who attended the clinics of the department of ...

By a cusp V we shall mean the image of the unit disk D under a bounded injective holomorphic map h into C whose derivative vanishes at exactly one point. The simplest example is the Neil parabola, given by h(ζ) = (ζ, ζ). See [3, 4] for background and theory on the Neil parabola, which is pictured in Figure 1. A generalization of a cusp is a petal. A petal is the image of the unit disk D under a...
