Background: This study aimed to determine the gender of a sample of Iraqi adults utilizing the mesio-distal width of maxillary canines, inter-canine width and standard maxillary canine index, and to determine the percentage of dimorphism as an aid in forensic odontology. Materials and methods: The sample included 200 sets of study models belong to 200 subjects (100 males and 100 females) with an age ranged between 17-23 years. The mesio-distal crown dimension was measured manually, from the contact points for the maxillary canines (both sides), in addition to the inter-canine width using digital vernier. Descriptive statistics were obtained for the measurements for both genders; independent samples t-test was performed to evaluate the gender difference, percentage of dimorphism was obtained and discriminant function statistics were used for gender identification in addition to the percentages of gender identification accuracy. Results: Generally, the mesio-distal width of the maxillary canine and the inter-canine width were larger in males than females with a high significant difference. The accuracy of genders determination using standard maxillary canine index was 44% for males, 74% for females and 59% for the combined sample, while it was 70% for males, 76% for females and 73% for the combined sample using discriminant function statistics depending upon the canines, inter-canine widths and maxillary canine index. The percentages of dimorphism were 6.13% for the canine mesio-distal width and 4.66% for the inter-canine width. Conclusions: Maxillary canines can be used in genders identification as an aid for forensic odontology.
Metaphor is a linguistic phenomenon related to people's cultures. It is an integral part of cultural heritage. This paper tackles the use of animal-based metaphors in the field of football club titles so as to draw comparisons between those in Russian with their counterparts in Arabic. Names of animals are used to refer to some clubs and teams, where these names or titles reflect animal features such as strength, preying on victims; or animal figures are employed in the club symbols, or due to the similarity of the club shirt to the animal outer shapes in colours. For instance, "an-Nawaris", which means gulls in English, is used to refer to az-Zawraa club du

The results of the present study show the biological effects of ethyl elcoholic and aquatic extracts as well as alkaloids compounds of Atriplex helmius and Capparis spinosa roots. The results demonstrated the superiority of the cold aqueous extract of C. capparis at the highest concentration of 20 mg / ml, as the killing rate was 81.16% for the second larval instar of Cx. pipiens after 72 hours of exposure. While, the killing rate caused by the same treatment was 79.52% for the third larval instar. The results also showed the superiority of the alcoholic extract against C. spinosa , as the killing rate reached 98.55% for the

Background: Histamine is one of the biogenic amines that belong among the naturally occurring substances. It can be formed in food as a result of metabolic processes of microorganisms .If the concentration of histamine is above a normal level (5mg/100g) this could possibly due to bacterial contamination of food harmful affect may occur.
Objective: The purpose of this study was to detect histamine forming bacteria and quantification of histamine in fresh meat product available in local meat markets in Baghdad.
Methods: Histamine level determination in some red meats product was performed by known colorimetric methods. This method enables a rapid and precise determination of histamine in many samples, in this study, total number of t

AbstractIn the field of construction materials the glass reinforced mortar and Styrene Butadiene mortar are modern composite materials. This study experimentally investigated the effect of addition of randomly dispersed glass fibers and layered glass fibers on density and compressive strength of mortar with and without the presence of Styrene Butadiene Rubber (SBR). Mixtures of 1:2 cement/sand ratio and 0.5 water/cement ratio were prepared for making mortar. The glass fibers were added by two manners, layers and random with weight percentages of (0.54, 0.76, 1.1 and 1.42). The specimens were divided into two series: glass-fiber reinforced mortar without SBR and glass-fiber reinforced mortar with 7% SBR of mixture water. All s
