because of on-call responsibilities, many medical residents are subjected to chronic partial sleep deprivation, a form of sleep restriction whereby individuals have chronic patterns of insufficient sleep. it is unclear whether deterioration in cognitive processing skills due to chronic partial sleep deprivation among medical residents would influence educational exposure or patient safety.twent...

The main result of this paper is to study the local deformations Calabi-Yau $$\partial \bar{\partial }$$ -manifold that are co-polarised by Gauduchon metric considering subfamily fibres class Aeppli/De Rham-Gauduchon cohomology given on central fibre. In latter part, we prove p-SKT h- -property deformation open constructing and studying a new notion called hp-Hermitian symplectic (hp-HS) form.

full mouth rehabilitation in patients with ectodermal dysplasia (ed) is difficult to manage, especially because the afflicted individuals are quite young when they are evaluated for treatment; therefore, esthetics is an important concern. this clinical report describes the rehabilitation of a 19-year-old girl diagnosed with ectodermal dysplasia. eleven implants were placed in the maxilla and ma...

the aim of this study was to determine the effect of trenched zirconia bar on the von mises stress distribution of ips -empress ii core ceramics.the three-dimensional model including a three-unit bridge from the second premolar to the second molar was designed. the model was reinforced with zirconia bar (zb), zirconia bar with vertical trench (vzb) and zirconia bar with horizontal trench (hzb) ...

statement of problem: targis restorations provide good esthetic and clinical success; however, improving marginal accuracy requires further investigations. purpose: the aim of this was to study evaluate the effect of relining on the marginal accuracy of ceromer crowns. material and methods: one ivorine maxillary central incisor was prepared for targis crown. 10 acrylic models were duplicated fr...

iron, cobalt and copper are metals, which appear together in many real samples, both natural and artificial. recently a classical univariate micellar colorimetric method has been developed for determination of these metal ions. the organized molecular assemblies such as micelles are used in spectroscopic measurements due to their possible effects on the systems of interest. the ability of micel...
