Background: Acrylic resin polymer s used in prosthodontic treatment as a denture base material for several decades. Separation and debonding of artificial teeth from denture bases present a laboratory and clinical problem affect patient and dentist. The aim of this study is to evaluate the effect of oxygen plasma and argon plasma treatment of acrylic teeth and thermocycling on bonding strength to hot cured acrylic resin denture base material. Materials and Methods: Sixty denture teeth (right maxillary central incisor) are selected. The denture teeth are waxed onto the beveled surface of rectangular wax block according to Japanese standard for artificial teeth.

The Audit evedances represent the reconciliation tools between the Financial data shown on financial statements, and the level of satisfaction level of the Auditor about these statements. According that, the Auditor try to achieve the highest quantity of These evidances, and the most satisfactive of it…, but that will be so hard sometimes, when the internal controlling system is not good, and when the Auditor had some satisfied evidences, but not sharp… So, this research comes to inspect the relation between the quantity, and the level of satisfaction, and argument to prove that evidences gives. This research assumes that getting enough evidences leads to reduce faults, improves the auditing operation, and avoids risks. The research

Show MoreThe process of coordination and joint cooperation between SAIs and internal auditors in the public sector is considered one of the very important matters in performing efficient audits and are of high quality, especially if this coordination and cooperation is implemented in accordance with international standards, as it leads to avoiding duplication in auditing work. And the distribution of work in a distribution that achieves the objectives of auditing in general and is of general benefit to the economic unit.

Show MoreBackground: The objective of this study was to investigate the possibility of standardizing the Bolton ratio analysis as a diagnostic measure for both Iraqi and Egyptian orthodontic populations within three Angle' classification groups. Materials and methods: Two hundred forty pretreatment study casts (one hundred twenty of each population) were included in this study and divided into three Angle' classification groups. The mesiodistal crown diameters of all teeth were measured for computing the anterior and total Bolton ratios. Analysis of variance was performed to compare the mean ratios of Bolton analysis as a function of the Angle classification.HSD test was used to specify the classes of malocclusion that have significant differences.

Ethanol extracts were examined singly or in combination with some drugs in their biological activity against some pathogens causing skin infection. Ethanol extract was applied at a concentration of 40 mg/ml for the treatment of induced skin infection of mice. Among the topicals used, Claforan was found the most effective on microorganisms causing skin diseases; ethanol extract was more effective than the drug Candimazole solution 1%. HPLC was used for the determination of azulene and apigenin active compounds of chamomile plant.

Background: Malnutrition in human life may adversely affect various aspects of growth at different stages of life. Teeth are particularly sensitive to malnutrition. Malnutrition may affect odontometric measurement involving tooth size dimensions. The aim of this study is to estimate the effect of nutrition on teeth size dimension measurements among children aged 5 years old. Materials and methods: This study was conducted among malnourished group in comparison to well-nourished group matching with age and gender. The present study included 158 children aged 5 years (78 malnourished and 80 well-nourished). The assessment of nutritional status was done by using three nutritional indicators, namely Height-for-age, Weight-for-age and Weight-fo

They were based on the monthly data of old aged people in Baghdad and the governorates except for the Kurdistan region from 2016 to 2019. Using BoxJenkins methodology, the stationarity of the series was examined. The appropriate model order was determined, the parameters were estimated, the significance was tested, adequacy of the model was checked, and then the best model of prediction was used. The best model for forecasting according to criteria of (Normalized BIC, MAPE, RMSE) is ARIMA (0, 1, 2)

Dust particles from storms are one of the main atmospheric constituents that affect the air quality and the Earth’s climate system. Monitoring of these atmospheric constituents is only possible through satellite measurements because ground based measurements are very limited in space and time and these constituents get transported over long distance from their source region. Absorbing Aerosol index is a qualitative parameter however it does excellent job in classifying UV absorbing and non absorbing aerosols. In most areas, we can classify dust storms by the broad meteorological conditions that cause them. The AI is a measure of the change of spectral contrast in the near ultraviolet (with respect to a purely molecular atmosphere) brou

The texture of the dust samples were ranged from sandy silty clay (71.4%) to sandy clayey silt (28.6 %).The mineralogical composition of the sand fractions included Quartz (52.2%, ), feldspar (6.4%, ), calcite (33%, ), gypsum (5.6%, ), dolomite (1.5%,) and heavy minerals (1.3%,). The clay minerals present included Chlorite, Illite, Montmorillonite, Palygorskite and Kaolinite. The results of heavy minerals analyses indicated that they were opaque heavy mineral, pyroxene, hornblende, zircon, chlorite, epidote and garnet.

A simple chemical method for producing ZnO/ CuO/ CdS nanoparticles using a chemical route (SILAR) method has been utilized. XRD patterns show hexagonal structures for ZnO, spheres, and cubic-formed CuO/CdS nanoparticles. Nanoparticles showed a blue shift in their UV-VIS energy band edge with (3.7, 3, and 3.2) eV for ZnO, CuO, and CdS. The morphology of ZnO, CuO, and CdS nanoparticles is investigated using scanning electronic microscopy (SEM). The XRD pattern reveals that the crystallites size are 15–30 nm. Photoluminescence reveals a yellow-green (520 nm) region for ZnO, a blue (380 nm) region for CuO, and a red (440 nm) region for CdS. The CdS wideband gap restricts its application. In this manner, we combined ZnO, CdS, and CuO for th
