The purpose of this study was to evaluate the effect of pulsed Nd:YAG laser on the dentin surface by scanning electron microscope (SEM) in order to determine the optimum time and power of radiation to seal the exposed dentinal tubules. Horizontal sections were taken from newly extracted impact third molar teeth. Smear layers from the dentin surfaces were removed by phosphoric acid and all sampl...
چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
One of the main tasks of the control systems in the wind turbines is to maintain the power of the wind when its wind speed proceed its nominal value. Because the failure to maintain the power in its nominal value in the region of the turbine curve damages the turbine and increases the mechanical stress. This object is obtained by controlling the pitch angle in the third region of the turbine cu...
Starting with Kenny and Judd (1984) several methods have been introduced for analyzing models with interaction terms. In all these methods more information from the data than just means and covariances is required. In this paper we also use more than just firstand second-order moments, however we are aiming to adding just a selection of the third-order moments. The key issue in this paper is to...
The notion of ‘power of judgement’ in the title of Kant’s Critique of the Power of Judgement is commonly taken to refer to a cognitive power inclusive of both determining judgement and reflecting judgement. I argue, first, that this seemingly innocuous view is in conflict both with the textual fact that Kant attempts a critical justification of the reflecting power of judgement – only – and wit...
this thesis examines the significances and implications of inflicted physical pain in waiting for the barbarians (1980) by john maxwell coetzee (1940 - ). the researcher tries to show how body becomes a site for exercising violence. in this way, the government’s representatives turn bodies of the barbarians into blank pages through torturing in order to create the truth of the empire. in this p...
A new structure is presented for digital delta-sigma modulator (DDSM). Novel architecture decreases hardware consumption, output quantization noise and spurs in Comparison to previous architectures. In order to reduce the delay, power consumption and increase maximum working frequency, the pipelining technique and the carry skip adder are used. Simulation proposed architecture shows that the qu...
Background: While many dental procedures induce pulpal damage by increase the temperature, this study was established to evaluate the thermally effect of different laser methods on pulp, oral soft and hard tissues. Objectives: In this study, laser irradiation applied to measure how increased in power output can influence on dental pulp by using CT images. Methods: Ten adult New Zealand white ra...
Finding minimum number of connecting lines is as important as locating power quality monitors (PQMs) for full observability of power system. Therefore, a PQM placement method should determine both optimum buses and lines, since utilities can make better decisions for monitoring of power system with this information. This paper attempted to propose a new method to locate the PQMs at various unob...
The aim of the present study was to examine the effect of gender and social class differences on locus of control in a group of Junior high school students. 144 students at second and third grades of school were randomly selected by using a cluster sampling procedure. Subjects completed the Nowicki-Strickland locus of control scale, which were adopted for Iranian population by Khair (25). Khair...
