Torsion of Elliptical Composite Bars Containing Neutral Coated Cavities
Using complex variable methods and conformal mapping techniques, we establish the existence of coated cavities of various shapes that do not disturb the warping function in a host elliptical bar. These cavities are known as ‘partly neutral cavities’. Our results show that the two axes corresponding to the neutral elliptical coating are parallel to those of the host elliptical bar and that the c...
متن کاملMagnetic Focusing of Composite Fermions through Arrays of Cavities.
The magnetoresistance Rxx was investigated in arrays of abutted square cavities with lengths L ranging from 500 nm to 1.2 mm near filling factor n 1y2. Maxima in Rxx occur for effective magnetic field values satisfying the magnetic focusing condition between the cavity spacing and the cyclotron radius of composite fermions, also for the effective magnetic field direction when composite fermio...
متن کاملMicroleakage in combined amalgam/composite resin restorations in MOD cavities
Aim: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. Methods: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of pulpal floor. Dental tissues were etc...
متن کاملEffect of Cavity Dimentions with the Same C-Factor on Micro Leakage of Composite Resin Cavities
Abstract Background and aim: Given the prevalence of microleakage in composites and their known complications and lack of reporting of the influence of cavity depth and diameter on the same c-factor on the microleakage of composite cavities, this study investigated the effect of microleakage on composite cavities in identical C Factors. Materials and Methods: In this experimental study on 40 ...
متن کاملIn-Vitro Evaluation of Microleakage of Class II Cavities Restored with Bulk-Fill Flowable Composite
Background and Aim: Composite placement poses many challenges, especially in the gingival floor with dentinal margins. Microleakage is one of the factors affecting the longevity of dental restorations. We aimed to compare the microleakage of cavities filled with bulk-fill composite at enamel and dentinal margins. Materials and Methods: In this experimental study, a total of 102 sound human pre...
