Abstract
Abstract Objective: To measure and compare bracket transfer accuracy of five indirect bonding (IDB) techniques. Materials and Methods: Five IDB techniques were studied: double polyvinyl siloxane (double-PVS), double vacuum-form (double-VF), polyvinyl siloxane vacuum-form (PVS-VF), polyvinyl siloxane putty (PVS-putty), and single vacuum-form (single-VF). Brackets were bonded on 25 identical stone working models. IDB trays were fabricated over working models (n = 5 per technique) to transfer brackets to another 25 identical stone patient models. The mesiodistal (M-D), occlusogingival (O-G), and faciolingual (F-L) positions of each bracket were measured on the working and patient models using digital photography (M-D, O-G) and calipers (F-L). Paired t-tests were used to compare bracket positions between working and patient models, and analysis of variance was used to compare bracket transfer accuracy among the five techniques. Results: Between the working and patient models, double-VF had the most teeth with significant differences (n = 6) and PVS-VF the fewest (n = 1; P

Each of the accelerators tested earlier showed the potential to irradiate no more than 20 thousand m3 per day, which is many times less than practical needs. At the same time, there are no power restrictions for existing high-voltage generators, which can serve as a key prerequisite for creating hi...

Assuming the second slow-roll parameter as a constant leads to a first-order differential equation for β-function which much easier to solve and find a solution than the second (non-linear) order equation that we have in the corresponding standard constant-roll inflation. Many cosmological models are known as a subclass of k-essence, so we will try to consider the ...

SivaramAbstractObservations have indicated that we do not see neutron stars (NS) of mass near the theoretical upper limit as predicted. Here we invoke the role of dark matter (DM) particles in star formation, and their role in lowering the mass of remnants eventually formed from these stars. Massive stars can capture DM particles more effectively than the lower mass stars, thus further softening the equation of state of the remnant neutron stars. We also look at the capture of DM particles by ...

The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscope (HRTEM), X-ray photoelectron spectroscopy (XPS), Raman, electron spin-resonance (ESR) and surface photovoltage spectroscopy (SPS). The results reveal that SCFs c...
