Thin films (20-150 nm thickness) of poly(o-anthranilic acid) with various doping levels were prepared on silicon substrates with deposited indium tin oxide, and their topography and current-voltage (I-V) characteristics were quantitatively investigated using current-sensing atomic force microscopy with a platinum-coated tip. The films were found to have a surface morphology like that of orange ...
Background and Aim: Diode laser is a great choice for soft tissue surgery. The diode laser is partially absorbed by hard dental tissues, making it safe for soft tissue surgery. This study aimed to compare the tissue thermal changes induced by three types of diode lasers at 810, 940, and 980nm wavelengths. Materials and Methods: In this in-vitro experimental study, using a diode laser device (c...
A five-terminal ~ 15-V monolithic voltage regulator has been developed that incorporate internal frequency compensation and internally provides a &I percent output voltage tolerance. In addition, a thermally symmetric layout design of the chip hae been used to eliminate the detrimental effects of thermal feedback Manuscript received May 26, 1971; revised August 9, 1971. The author is with the S...
In modern software, crypto-algorithms are widely used for both data encryption tasks, and authentication integrity checks. There well-known proven crypto-algorithms. Their cryptoresistance is either mathematically or based on the need to solve a complex problem (factorization, discrete logarithm, etc.). On other hand, in computer world, information constantly appears about errors «holes» partic...
Background and Aim: Bacterial disinfection is considered as the primary etiology of pulpal and periapical lesions and as the result, adequate elimination of such infections is one of the purposes of root canal treatment; But since this purpose is impossible to achieve, reducing the bacterial load seems to be as a rational goal. Diode lasers have made their way into endodontics for better disinf...
