Impact of bitter taste threshold on caries experience in relation to ABO blood types among dental students at Al Kufa University
...Show More Authors

Background: Blood group system and the ability to taste phenylthiocarbamide (PTC) are the most studied traits in human genetics which have been extensively used in describing genetic variations among human populations around the world that may had an effect on dental caries. The aims of present study were to investigate the caries experience among students with different bitter taste threshold in relation to blood type. Materials and Methods: The sample of present study includes dental students female aged19-21 years. The diagnosis of dental caries was done according to the criteria of Manjia et al, 1989 recording decayed lesion by severity (D1-4) MFS. Furthermore, bitter taste sensitivity was measured according to PTC (phenylthiocarbamide) test while concerning blood types, depending on the identity student’s. Statistical analysis that used in this study can be classified into two categories: Descriptive Analysis and second Inferential analysis (Levene test, One-way Analysis of Variance). Results: The data of present study demonstrated that the differences in caries experience among different bitter taste threshold were found statistically not significant although the higher mean value for the higher grades of caries severity (D2-3) were among medium taster students while the non-taster group had the higher mean value of D1. Concerning difference in caries experiences among students with different bitter taste threshold for blood types were not significant in spite of grade D1 was found higher among non –taster A, AB blood type students while for O blood type students were found within super taster. While grade D4 severity was found higher with medium taster among students with A, AB blood types while found higher with super taster among students with O type as grades D4 were absent among students with B blood type. Conclusion: Bitter taste perception which identified according to ptc test has some effect on dental caries experience and were found different for different blood type

Frame-Based Change Detection Using Histogram and Threshold to Separate Moving Objects from Dynamic Background
...Show More Authors

      Detecting and subtracting the Motion objects from backgrounds is one of the most important areas. The development of cameras and their widespread use in most areas of security, surveillance, and others made face this problem. The difficulty of this area is unstable in the classification of the pixels (foreground or background). This paper proposed a suggested background subtraction algorithm based on the histogram. The classification threshold is adaptively calculated according to many tests. The performance of the proposed algorithms was compared with state-of-the-art methods in complex dynamic scenes.

impact of mental games on improving shooting accuracy among young basketball players in Iraqi clubs
...Show More Authors

This study investigates the effectiveness of mental games in enhancing shooting accuracy among young basketball players. Initially, baseline shooting accuracy was assessed through tests conducted prior to a three-week intervention involving mental games. A follow-up test revealed a significant improvement in participants' shooting accuracy following the intervention. Given the noticeable differences in the new shooting scores compared to the initial assessments, a second set of pre-intervention tests was conducted. These tests reaffirmed the significant enhancement in shooting accuracy, substantiating the hypothesis that mental games positively affect performance. The findings highlight the importance of these intervention programs

Background: Little is known about asymmetry of children's dental arches, the purpose of this study was to verify the presence of asymmetry of dental arches among Iraqi children in the mixed dentition stage. Materials and methods: The sample included 52 pairs of dental casts, 27 pairs belong to males and 25 pairs for females. Three linear distances were utilized on each side on the dental arch: Incisal-canine distance, canine-molar distance and incisal-molar distance, which represent the dental arch segmental measurements using the digital sliding calipers, which is accurate up to 0.02 mm. Results: No significant sides' differences with high correlation coefficient were found between the right and left incisal-canine, canine-molar and in
