Abstract

A promotion to a previous computer programmed technique "Photo-Micro Estimation Program" wascarried out to compute the exact dimensions of cell and cell fraction in photographs ofhistological sections. "Visual Basic 6" was used as a language for building of the antecedentapplication forms. With the aid of a slide micrometer, pixels were substituted for micrometer(μm). The new procedure was termed "Photo-histometry program".To test the suitability of this program, eight photographs of histological sections were selectedrandomly to be tested. Results were contrasted with those calculated by using ocular lens(calibrated by a slide micrometer).Estimation of RBC diameter (well known, =7-8 μm) was the second step in assessing theadequateness of this new program.Results revealed that this program was simple, fast, adequate and accurate. It was better than thecalibrated ocular lens in being more precise (it enumerates up to the fractions of a micrometer)

Abstract

The aim of this study is to evaluate the post-treatment changes in the dental parameters measured at study models in group of Iraqi patients with different Angle's classes of malocclusions. Materials and Methods: 113 Iraqi patients (42 males and 71 females) ,of 14-29 years old at beginning of treatment, were randomly selected and longitudinally assessed in respect to relapse of their orthodontically treated dentitions. Stone study models were taken before treatment, after orthodontic treatment and a third set was obtained approximately 1 month out of retention. Study models were photographed using a digital camera which is mounted on a height-adjustable tripod; with standard camera to object distance. Indirect computer digitization is used; in which the photographs are entered to memory of Pentium IV computer and analyzed using View Box version 3 software allowing data to be directly digitized in the computer and analyzed with the SPSS program.10 variables are digitized :labial seg-ment ,buccal segment, vertical canine, vertical molar, diagonal arch length, inter canine width, inter-molar width, inter molar width, over bite and over jet. Changes in measurements on study models from (before treatment) to (after treatment) were calculated and Paired Student's t- tests were employed to test the changes in means from (after treatment) to (after retention); at P=<0.05 Results: The pooled sample was divided according to Angle's classifications into groups, the results indicate that the changes are varied and ranged from statistically non significant for some variables to significant for the rest. While for Class I crowding patients; the changes are small and statistically non significant for most variables. For Class I spacing patients; a tendency for relapse for most variables were observed. In Class II. D1 crowding, Class II. D1 spacing, Class II. D1 without crowding or spacing, CII. D2 and Class III crowding patients some variables showed significant changes, and no significant difference for rest of variables. Conclusion: Relapse (post-treatment changes) in the dental parameters measured at study models varied among different Angle's classes of malocclusions at the 1-month follow-up. Class I crowding and CII.D1 without crowding or spacing subjects were relatively stable after treatment. Class II.D2; Class I spacing and Class II.D1 spacing subjects were relatively prone to relapse post treatment.

Abstract

Background and Objectives: Neck pain due to poor posture, if neglected for long time, can lead to development of the cervical spondylosis. This study was designed to analyze the relation between symptoms and signs originating from the cervical spine and the duration of computer use.Methods: A comparison of a group of male subjects who work on computer with those who do not work on computer whose ages range between (30 - 50) years was done for liability of cervical spondylosis. Any subject whose BMI is more than 25Kg/m2 was excluded. Likewise any subject with recognized evidence for predisposition to develop spondylosis was excluded.Employee from different establishments in Erbil City (200 Subjects), over a period of six months from January / 2008 were included in the study.Ninety nine subjects who use computer and hundred and one non-computer user. Subjects were subdivided into: First group: Computer user. Second group: Non-computer user. In both groups the duration of occupation ranges between four to sixteen year and hours of working/week range between (22-32 hours). The (99) subjects who work on computer each of them was evaluated for computer work station and asked about his posture during use of computer and asked if he takes a break time when he work for long hours.The difference between comparable subdivisions of the studied subjects was tested by the Chi-square test concerning the frequency of spondylosis in each of them.Results: Cervical spondylosis was statistically significant among those who use computer (P< 0.05).Conclusions: Long term use of computer with bad posture and with out break time increase liability for developing cervical spondylosis in comparison of (same age group, same duration of occupation ,and same hours of working) but not using computer. Proper posture and take a break time when using computer for long time is necessary.

Abstract

Background: Surface contamination of public user interface systems such as computer keyboards and mouse devices may play a role in community-acquired outbreaks by acting as an environmental vehicle in transmission of potential hazardous microorganisms. There is no economical way to test all keyboards and mice out there, but there is a common-sense way to prevent bacterial contamination or eliminate it if it exists.Objectives: To explore the bacterial contamination rates in multi-user and single-user computer accessories (keyboards and mouse devices) in certain colleges of the Diyala University.Materials and methods: This study was conducted in Bacteriology laboratory- Colleges of Veterinary Medicine- Diyala University for the period from October 2012 to April 2013. A total of 155 swabs were collected aseptically from 60 computers in 4 colleges, namely, College of Medicine, Veterinary Medicine, Science, and Education- Pure Science. Swabs were streaked on blood and MacConkey's agar plates then incubated for 24 hours at 37 ̊ C. Final identification of bacterial species was based on standard bacteriological and biochemical criteria.Results: The results showed that the overall contamination rate in the four colleges was (54.8%). The highest isolation rate of bacterial contaminant was Staphylococcus epidermidis (30.6%), followed by Escherichia coli (29.4%). Fungi constitute (17.6 %) of isolates. The College of Veterinary Medicine rank at the top with significant highest contamination rate (52.7%), followed by the College of Medicine with a contamination rate (21.2). Computers of the internet centers harbor the significant highest contamination rate compared to administrative units (71.8% and 28.2%) respectively. The contamination rate was higher in mouse devices compared to keyboards (57.6% vs 42.3%).Conclusion: The study concluded that continuous education of students and employees about the risk of bacterial contamination arise from using the computers, beside the periodic disinfection of computer accessories may aid the fight against transmission and spreading of infectious pathogens.

Abstract

The aim of this paper is to improve the Dijkstra algorithm which is widely used in the internet routing. Quantum computing approach is used to improve the work of Dijkstra algorithm for network routing by exploiting the massive parallelism existing in the quantum environment and to deal with the demands of continuous growing of the internet. This algorithm is compared according to the number of iterations and time complexity with Dijkstra’s algorithm and the result shows that the quantum approach is better in finding the optimal path with better time complexity when it is implemented in quantum computer.

Abstract

as we know that information hiding techniques are researched and used in different aspects and using different cover media to wrap the secret message or information inside it yet the usage of a computer virus as a cover media, host or a carrier is a little bit extreme.this is a paper that shows the most important things to concentrate on when hiding secret information into a virus regarding of the types and behavior of both the virus itself and the person monitoring the communication media or the stego-analyst knowing that the reaction of the antivirus is in the benefit of the secrecy of the information
