PURPOSE This study aimed to investigate whether dentin surface preparation with diamond rotary instruments of different grit sizes affects the shear bond strength of resin-bonded restorations. MATERIALS AND METHODS The buccal enamel of 60 maxillary central incisors was removed with a low speed diamond saw and wet ground with silicon carbide papers. The polished surfaces of the teeth were prep...

In this study, we present proof of concept for an x-ray detector. The hybrid device consists a synthetic single crystal diamond in mechanical contact with piezoelectric lithium niobate surface acoustic wave (SAW) delay line. Upon irradiation, the experiences change conductivity, which, turn, very sensitively influences SAW transmission on This attenuation is directly used to monitor beam intens...

This paper presents a comprehensive review of diamond electronics from the RF perspective. Our aim was to find and present the potential, limitations and current status of diamond semiconductor devices as well as to investigate its suitability for RF device applications. While doing this, we briefly analysed the physics and chemistry of CVD diamond process for a better understanding of the reas...

Since the initial research leading to the production of diamond composite materials, there have been several important developments leading to significant improvements in the properties of these superhard composite materials. Apart from the fact that diamonds, whether originating from natural resources or synthesised commercially, are the hardest and most wear-resistant materials commonly avail...

The demand for liquefied-natural-gas-fueled tanks on ships is growing in accordance with IMO 2020 regulations. use of high manganese steel has increased recently, as this material can be applied at cryogenic service temperatures according to IGF code and economic advantages over other materials. In study, the heat input welding process, which involves one-side submerged arc (SAW) cut wire, inve...

This paper deals with the measurement and simulation of saw wire temperature during machining a rock sample in vacuum. It is expected for wire-sawing to keep cutting performance by successive supply edges. The vacuum has been investigated lunar planetary explorations. To clarify deterioration due nickel adhesion on rock, rise was investigated. In experiment, reciprocated slider-clank mechanism ...

Detection of AC magnetic fields at the nanoscale is critical in applications ranging from fundamental physics to materials science. Isolated quantum spin defects, such as nitrogen-vacancy center diamond, can achieve desired spatial resolution with high sensitivity. Still, vector magnetometry currently relies on using different orientations an ensemble sensors, degraded resolution, and a protoco...

The previous lectures gave us a good understanding of how to reason about [·] properties of programs. We saw how to decompose in logic properties of the form [α;β]P and [if(Q)α elseβ]P etc. That is all good and useful, but we need to remember that [α]P means that P holds after all runs of program α. Since while programs α are deterministic and, thus, have at most one run, the formula [α]P , in ...
