Background : Fractures are the most undesirable thing in endodontically treated teeth. The main reason teeth has a considerable risk for fractures is loss of tooth structure. Objective This study aims to determine effect access cavity preparation and instrument taper percentage on upper premolar fractures. Material Methods Twenty-four samples were stored sterile saline solution. sample was divi...

We propose a protocol for creating entanglement within a dissipative circuit QED network architecture that consists of two electromagnetic circuits (cavities) and two superconducting qubits. The system interacts with a quantum environment, giving rise to decoherence and dissipation. We discuss the preparation of two separate entangled cavity–qubit states via Landau–Zener sweeps, after which the...

The oral cavity is the primary site of verbal human communication. It has many additional important functional roles, including bolus preparation and formation, taste, and deglutition. Oral cavity cancer treatment, particularly for advanced tumors (because of radical surgery), destroys the integrity of this area. Extensive reconstructive efforts are required to maintain oral continuity, to faci...

Traditional techniques for the insertion of femoral stems in arthroplasty of the hip in osteopetrosis carry a considerable risk of penetration of the femoral cortex and intra-operative fractures, due to obliteration of the intramedullary cavity and greatly increased stiffness and brittleness of the bone. In order to reduce the risk of such complications we manufactured a customised stem and a c...

this paper is a computational study of the behavior of aerodynamics  characteristics of an airfoil with blunt trailing edge and  studies the effects aerodynamic performance caused by modifications made to the trailing edge. blunt trailing edge airfoils are of interest in the engineering of large wind turbine blades because they allow for a strong structure with a high aerodynamic lift to struct...

adhesive (green). _Besides the physical and mechanical properties of dental amalgam, one of the main reasons for its success is its clinical simplicity and forgiving technique. The derisory “drill and fill” slogan associated with dental treatment pertinently describes the provision of an amalgam restoration. The usual protocol for amalgam restorations is a single-stage procedure. Following deca...

We engineer a quantum bath that enables entropy and energy exchange with a one-dimensional Bose-Hubbard lattice with attractive on-site interactions. We implement this in an array of three superconducting transmon qubits coupled to a single cavity mode; the transmons represent lattice sites and their excitation quanta embody bosonic particles. Our cooling protocol preserves the particle number-...
