Background: Different soldering techniques have a variety of applications in dentistry. One of the most important uses of soldering is to join multiple-unit fixed partial dentures together. In this Study, two base metal alloys (Supercast and Minalux) were soldered  and their tensile, compressive and flexural strengths were measured and compared to each other. Materials and methods: In this ...

OBJECTIVE Analysis of mechanical measurements in laparoendoscopic single-site surgery (LESS) is important for instrument design and surgical simulators. The aim of this study was to develop a measuring system for different instruments and manipulations in LESS using a single-incision laparoscopic surgery (SILS) port. METHODS The loads on the SILS port were applied and recorded by the universa...

The aim of this study was to evaluate and compare the fracture resistance definitive zirconia dioxide restorations obtained using a computer-aided design manufacturing (CAD/CAM) system. Methods: Two groups ten samples were analyzed for each material (n: 20); first group Zolid Gen X Amann Girrbach (ZGX) second Cercon HT Dentsply Sirona (CDS). designed with identical parameters milled CAD/CAM Eac...

We construct a two-dimensional Turing machine that is physically universal in both the moving tape and head model. In particular, it mixing of all finite orders models. also provide variant model, but not

The one-body reduced density matrix $\gamma$ plays a fundamental role in describing and predicting quantum features of bosonic systems, such as Bose-Einstein condensation. recently proposed functional theory for ground states establishes the existence universal $\mathcal{F}[\gamma]$ that recovers correlations exactly. Based on novel decomposition $\gamma$, we have developed method to design rel...

In this paper, we improve some previous definitions of fuzzy-type Turing machines to obtain degrees of accepting and rejecting in a computational manner. We apply a BFS-based search method and some level’s upper bounds to propose a computational process in calculating degrees of accepting and rejecting. Next, we introduce the class of Extended Fuzzy Turing Machines equipped with indeterminacy s...

Objectives: Evaluate the influence of several methodological variables on the shear bond strength of in vitro studies. Methods: 105 bovine incisors were sectioned at the cervical level. The coronary portion was included in PVC rings, fulfilled with auto polymerized acrylic resin, with its labial surfaces positioned upward. All the samples were prepared for bonding, cleaned and acid etched on th...
