introduction: epulis fissuratum is often formed as a result of a poor fitting denture. the conventional treatment for this fibrous hyperplastic tissue is to excise it using a scalpel and to close the wound by a continuous or an interrupted suture. the increased utilization of lasers in dentistry also includes the utilization of carbon dioxide (co2) lasers in place of surgical scalpels in soft t...

Accuracy is the key issue in the precision forging. Geometric and dimension errors are the two significant defects found in most of near net or net shape manufacturing process. It becomes more critical for complex part such as an AUV propeller blade. In this study, geometric error was quantified by comparing the blade profile obtained from nominal geometry of the blade and the profile construct...

The rigid body motion can be represented by a motor in geometric algebra, and the motor can be rewritten as a trinometric function of the screw blade. In this paper, a screw blade strapdown inertial navigation system (SDINS) algorithm is developed. The trigonometric function form of the motor is derived and utilized to deduce the Bortz equation of the screw blade. The screw blade SDINS algorith...

The standard guillotine-shaped vitreous cutter blade (hereafter named Regular Blade [RB]) did not substantially change over the past 40 years, because of its simple and robust design. The asynchronous suction and cutting action, typical of RB blades, determines complete port obstruction generating flow instability and fluid acceleration that results in limited efficiency and eventually retinal ...

This research describes aerodynamic characteristics of small-scale wind turbine blade, called Archimedes spiral wind turbine blade. Numerical approaches on the prediction of aerodynamic performance of the blade have been conducted. Both steady and unsteady state numerical simulations using ANSYS CFX are performed on the several cases of rotating speeds. Large scale tip vortex is captured and gr...

Currently, the TiO2/CdS photoanodes based dye-sensitized solar cells (DSSCs) have shown extraordinary developments in photo-conversion efficiency. In this report, pristine TiO2, CdS and various molar ratios of were prepared by one step microwave irradiation route followed doctor blade method. The sheet-like morphology TiO2 nanoparticles clearly evident from SEM TEM images. A significant reducti...

Blade configuration of nanofluids has been proven to perform much better than dispersed configuration for some heat conduction systems. The analytical analysis and numerical calculation are made for the cylinder--shaped and regular-rectangular-prism--shaped building blocks of the blade-configured heat conduction systems (using nanofluids as the heat conduction media) to find the optimal cross-s...

the obesity epidemic raises important and complex issues for clinicians and policy-makers, such as what clinical and public health measures will be most effective and most ethically-sound. while nir eyal’s analysis of these issues is very helpful and while he correctly concludes that “conditioning the very aid that patients need in order to become healthier on success in becoming healthier” is ...

background: many of health system services are done in clinical counseling. a patient’s expectation of clinical consultation and physician office visits is to obtain diagnostic-remedial results, while such an expectation can be fulfilled only through an active relationship between the doctor and the patient. the aim of this study is to evaluate the quality of doctor- patient interaction in an e...
