Background: Dental caries and periodontal disease are the most common and widely spread diseases affecting humans at different ages. Aim of this study is the assessment of prevalence and severity of dental caries, gingivitis, oral hygiene and enamel anomalies in relation to gender and residency among 15 years old students in Maysan governorate –Iraq. Materials and methods: The total sample composed of 750 students (400 males and 350 females, 450 urban and 300 rural) selected randomly from different high schools in the Governorate. Diagnoses and recording dental caries was according to the criteria of WHO (1987), Plaque index of Silness and Loe (1964) was used for plaque assessment, Ramfjord index (1959) was applied for the assessment of calculus, gingival index of Loe and Silness (1963) was followed for recording gingival health condition and criteria of WHO (1997) to assess enamel anomalies. Results: Caries prevalence was found to be (92.53%) of the total sample. The DMFS value was higher among females compared to males with statistically high significant difference (P<0.01) also the value was higher among rural compared to urban with statistically high significant difference (P<0.01). Plaque, gingival and calculus indices were higher among rural than urban and higher among males than females, statistically, there were high significant differences regarding plaque and gingival indices (P<0.01) while non-significant difference regarding calculus index (P>0.05), for both genders and residencies. Conclusion: A high prevalence of dental caries and gingivitis were recorded indicating the need of a public health programs in this governorate.
Vocational stresses and their relation with the level of ambition among the lecturers of the university In general , vocational stresses affect the attention and the process of focusing making individual busy with solving of his daily problems instead of his job. The vocational stresses , anxiety and tension are factors effecting the physical and psychological ability of the individual. This study aims to measure the vocational stresses among the lecturers of the university , to measure the level of ambition among them, to identify the statistical differences significant among them according to sex variable, to identify the differences significant in level of ambition among them according to sex variable and to identify the correlation r

From this relationship the values of variables are predicted. In this paper the multiple linear regression model and three covariates were studied in the presence of the problem of auto-correlation of errors when the random error distributed the distribution of exponential. Three methods were compared (general least squares, M robust, and Laplace robust method). We have employed the simulation studies and calculated the statistical standard mean squares error with sample sizes (15, 30, 60, 100). Further we applied the best method on the real experiment data representing the varieties of

Bac kground:: Multidrug resistant methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of nosocomial and community acquired infections. The glycopeptides vancomycin has been proposed as the drug of choice for treating such infections; this lead to the emergence of vancomycin intermediate sensitive S. aureus (VISA) and vancomycin resistant S.aureus (VRSA).
Objjec tt iiv es :: To identify the vancomycin resistance both phenotypically and genotypically among MRSA isolates from different hospitals and to determine the sensitivity of these isolates to different antimicrobial agents
Metthods:: A total of 204 S. aureus isolates were obtained randomly from various clinical specimens including (wound swab, burn swab, ear swab
The phenomenon of delayed marriage triggered the intention of most researchers and specialists to reveal the social factors associated with the spread of this phenomenon in order to identify the characteristics of that phenomenon and the social factors resulting from it. Thus, the current research aims to identify the social factors most related to the delay in marriage age among working-women at the University of Baghdad, represented by family factors, economic factors-professional, psychological factors – subjective, and environmental factors. The researcher also aims to identify the differences in social factors associated with late marriage age for working women at the University of Baghdad in terms of the type of profession (teach

The researcher used the descriptive approach in investigating the relationship between neuromuscular coordination and setting and spiking skills. The sample of the research was selective and composed of 45 youth players of the Specialized Football Tennis School in Baghdad Province with age of 16 years and above. The research sample was subjected to the relevant tests and the results obtained analyzed statistically to establish whether there is a relationship between neuromuscular coordination and setting skill on the one hand and neuromuscular coordination and spiking skill on t
