Investigating the Effects of Carbon Dioxide Laser Fluence on Oral Soft Tissue
...Show More Authors

This study investigates the surgical and thermal effects on oral soft tissues produced by CO2 laser emitting at 10.6 micrometers with three different fluences 490.79, 1226.99 and 1840.4 J/cm2. These effects are specifically; incision depth, incision width and the tissue damage width and depth. The results showed that increasing the fluence and /or the number of beam passes increase the average depths of ablation. Moreover, increasing the fluence and the number of beam passes increase the adjacent tissue damage in width and depth. Surgeons using CO2 laser should avoid multiple pulses of the laser beam over the same area, to avoid unintentional tissue damage.

The Effect of Additives on The Performance of Hydrostatic Thrust Bearings
...Show More Authors

 

The paper is concerned with, the behavior of the hydrostatic thrust bearings lubricated with liquid-solid lubricants using Einstein viscosity formula, and taking into account the centrifugal force resulting from high speed.  Also studied is the effect of the bearing dimensions on the pressure, flow rate, load capacity, shear stress, power consumption and stiffness.

The theoretical results show an increase in load capacity by (8.3%) in the presence of solid graphite particles with concentration of (16%) by weight as compared with pure oil, with increasing shear stress.  .

In general the performance of hydrostatic thrust bearings improve for load carrying capacity, volume flow rate,

Effect of Combined Oral Contraception on Coagulation Profiles in Women Attending Fertility Control Clinic in Baqubah City- Iraq
...Show More Authors

Background: Use of oral contraception has been associated with an increased abnormalities of lipid and carbohydrate metabolism as well as hemostatic variables at baseline (increased plasma levels of factor VII, factor X, fibrinogen and of D-dimers).
Objectives: To evaluate the effect of oral contraceptive pills (combined pills) on coagulation tests,prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen level.
Patients and methods: This is a descriptive cross sectional study which was conducted in fertility control clinic in Al-Batool Teaching Hospital for Maternity and Children in Baqubah city, during the period from December 2015 to October 2016. Eighty eight women were enrolled in this study according

The Legal Effects of Breaching the Administrative Contract : A Comparative Study
...Show More Authors

      The administration concludes two types of civil and administrative contracts, each of which is subject to its own system, and the administrative contract is characterized by a set of exceptional powers towards the contractor in order to compel him to implement his obligations

       And that administrative contracts require a large financial and technical possibility to implement them, especially contracts that focus on strategic projects, including general contracting contracts

      Which is based on the technical competence and merit of the contractor, and accordingly, delay in the implementation of contractual obligations or negligen

PDF Angular Laser Cleaning of Aluminum Al-4004 with Different Spot Sizes
...Show More Authors

Abstract: When it comes to applications in welding, cutting, and surface engineering, the utilization of high-power fiber-delivered beams from solid-state lasers offers several benefits. This paper addresses the issue of cleaning the surface of the samples with different spot sizes (50, 100 and 200) (industrial ytterbium fiber laser) to prepared it to be welded. Angular laser cleaning with incident angles (5, 10, 15, 20, 25, 30) ° with different powers (3, 5, 7, 10) W and hatch distance 0.001 was use for implemented.

Investigating the effect of cartographic properties on updating cadastral maps
...Show More Authors
Abstract<p>Cadastral maps are the main documents of ownership and plots of land, as it contribute to preserving the property rights of individuals and institutions. It indicates the size and shape of each parcel and reveals geographic relationships that affect property value. The Iraqi cadastral maps are in old coordinate system AL-nahrwan 1934 and lambert conformal conic projection. Therefore these maps are old and unfit for use. The main objective of this paper is to investigate the effect of cartographic properties on updating cadastral maps. This depends on studying the effect of conversion the projection and the datum of the cadastral maps of the study area from (datum: nahrwan34, projection: lambert confo</p> ... Show More

Generation of 629 nm Pulsed Laser Using an Optical Parametric Amplifier
...Show More Authors

The main purpose of this work is the construction of an optical parametric amplifier (OPA) to generate a 629 nm pulsed laser. KTP nonlinear crystals were used for both parametric oscillation and amplification. A singly resonant parametric oscillator (OPO) is constructed to generate a signal of 1.54 μm and idler of 3.4 μm when the OPO system is pumped by 1.064 μm Q – switched Nd: YAG laser. The signal was then mixed with the pumping beam in OPA system to form the wanted wavelength. The obtained optical conversion efficiency was 60%.

PDF Evaluation of 940 nm Diode Laser in Esthetic Crown Lengthening
...Show More Authors

Abstract Background: Crown lengthening is a surgical procedure that apically positions the gingival edge and/or removes supporting bone in order to increase the amount of supra gingival tooth structure for restorative or cosmetic purposes.

The objective of the study: The purpose of this study was to evaluate the efficacy of the 940nm diode laser in esthetic crown lengthening surgery through clinical observations, patient questionnaires, clinical photographs, and gingival healing following gingival operations. Material and methods: In this randomized clinical trial, 16 patients (11 females and 5 males) had their crowns surgically lengthened using a diode laser (940 nm) in continuou
