In Vivo Mechanical and Histological Evaluation of the Effect of Vacuum Storage and Ultra Violet Light Treatment of Titanium Implants on Osseointegration
...Show More Authors

Background: Titanium implant is widely used in dentistry because of its extraordinary biocompatibility and mechanical properties. To increase bone–implant connection and provide early loading after placement, implant is stored in different storage medium and treated with UV light. Both of them are applicable methods to increase the bioactivity of titanium and overcome the biological aging. This study was designed to assess the effect of vacuum storage method and air storage with and without UV light treated of Cp Ti implant mechanically and histologically. Materials and methods: Titanium screws were acid etched and prepared in four different modes using different storage methods (air or vacuum and, with or without UV treatment. The implant screws were stored 4 weeks and then implanted into rabbit's tibia for histological and torque removal examinations. Results: There was a significant increase in mean value of torque removal test for screws air treated with UV light, vacuum and vacuum treated with UV light (14.5 ,13.8 ,17.92 N.cm respectively after 2 weeks, and (21.5333, 22.5 ,26.47 N.cm respectively after 4 weeks) compared with air storage screws (8.4 N.cm after 2 weeks, and 11.4 N.cm after 4 weeks). Histological examination showed bone formation mineralization and maturation increased with advancing time for air treated with UV light, vacuum and vacuum treated with UV light screws. Conclusion: vacuum storage method and air storage with UV light treated methods of Cp Ti implant had great effect in increasing the osseointegration than air storage methods, while the vacuum storage and treated with UV light have synergistic effects on the biological properties of aged titanium surfaces.

Developing a Prosthesis Design using A Gearbox to Replicate the Human Hand Mechanism
...Show More Authors

Prosthetic is an artificial tool that replaces a member of the human frame that is  absent because of ailment, damage, or distortion. The current research activities in Iraq draw interest to the upper limb discipline because of the growth in the number  of amputees. Thus, it becomes necessary to increase researches in this subject to help in reducing the struggling patients.  This paper describes the design and development of a prosthesis for people able and wear them from persons who have amputation in the hands. This design is composed of a hand with five fingers moving by means of a gearbox ism mechanism. The design of this artificial hand has 5 degrees of freedom. This artificial hand works based on the principle of &n

Auditing the comprehensive electronic banking system to detect operational business risks (applied research)
...Show More Authors

Abstract:

                In light of the development in the banking environment and the increasing reliance on electronic systems in providing banking services and due to the intense competition witnessed by the banking sector, the need has emerged to apply the comprehensive electronic banking system, which works on the Internet in providing new and diverse banking services regardless of time and place by linking all branches to one central database, and despite the advantages achieved from the application of the comprehensive system, there is a set of risks that accompany the use of that system, What requires the auditors to develop the audit method in line with the size of the development in the

The indirect solar dryers with innovative solar air heaters designs: A review article
...Show More Authors
Abstract<p>The drying process is considered an effective technique for preserving foods and agricultural products from spoilage. Moreover, the drying process lessens the products' weight, volume, and packaging, which prompts a reduction in the products' transportation costs. The drying technique with solar energy represents an ancient method, still alluring due to solar energy abundance and cost‐effectiveness. In this article, the previous manuscripts concerned with studying and analyzing indirect solar dryer systems that utilize innovative solar air heaters (SAHs) are reviewed. The results and conclusions are discussed intensively to clarify the significance of utilizing this type of drying technique. The ef</p> ... Show More

Directing Techniques to Process the Radio Drama Script ( Khata'a Play as a Sample)
...Show More Authors

     The radio drama is considered to be one of the arts that is discovered after a long period of theater's discovery. Initially , it was the broad framework of the theater's work when radio was broadcasting the shows on the huge theaters. This beginning encouraged many of the radio specialists to correlate plays with radio and make a novice and distinctive type of art. Thus, radio drama made its first step including the following   ( plays, short and long series drama as well as other types of radio arts). Because of the above mentioned , the researcher is stimulating  to study directing techniques to process the radio drama script ( Khata'a play as a sample).

The first chapter deals with the

A New Feature-Based Method for Similarity Measurement under the Linux Operating System
...Show More Authors

This paper presents a new algorithm in an important research field which is the semantic word similarity estimation. A new feature-based algorithm is proposed for measuring the word semantic similarity for the Arabic language. It is a highly systematic language where its words exhibit elegant and rigorous logic. The score of sematic similarity between two Arabic words is calculated as a function of their common and total taxonomical features. An Arabic knowledge source is employed for extracting the taxonomical features as a set of all concepts that subsumed the concepts containing the compared words. The previously developed Arabic word benchmark datasets are used for optimizing and evaluating the proposed algorithm. In this paper,
