Background: Osteoporosis is a systemic skeletal disorder affects general health in addition to effect on salivary physical and chemical composition which lead to an adverse effect on oral health status. This study was conducted to evaluate the concentration of glycoprotein (osteonectin) in saliva and its effect on dental caries in relation to salivary flow rate and viscosity among osteoporotic women and compared to control group. Materials and Methods: The total sample composed of 60 females aged 60-65 years attending Al-Yarmook Teaching Hospital, 30 females diagnosed with osteoporosis by measuring bone density at the spine and femur with a dual-energy X-ray absorptiometry at T-score of >2.5, and 30 women without osteoporosis with T-score of ˂-1 (control group).The diagnosis and recording of dental caries was through the application of D1-4MFS index according to criteria of Mühlemman (1976). Stimulated salivary samples were collected under standardized condition, according to Tenovuo and Lagerlöf, (1994). The flow rate and viscosity were estimated and then the saliva was analyzed for estimation of glycoprotein (osteonectin) by using Enzyme-linked immunosorbent assay (ELISA). Results: The percentage of dental caries occurrence was 100% among osteoporotic group and control group. Results revealed that DMFS value was higher but statistically not significant among osteoporotic women, Concerning DMFS components, the data of the present study showed that the DS was lower but statistically not significant among osteoporotic women, while MS value was significantly higher among them (t=2.044, P<0.05, df =58), on the other hand the opposite figure was found concerning filling component FS however the difference was not significant. Correlation coefficients of caries experience with salivary flow rate revealed a weak negative not significant correlation with D1-4MFS and its component.On the other hand, the data of the present study showed that salivary viscosity correlate weakly not significant in negative direction with DS and its severity and in positive direction with MS, FS, DMFS.. The correlation coefficient between salivary osteonectin and dental caries were weak significant in positive directions concerning Ds and its severity except D3 and FS component as the relation were in negative direction, the positive not significant relation were also found between salivary osteonectin and MS,DMFS. Concerning the relation between salivary osteonectin and physical properties of saliva, the data of the present study revealed a non-significant relation in negative direction with salivary flow rate and in positive direction for salivary viscosity. Conclusions: Dental caries revealed lower percentage of occurrence among osteoporotic group.

A low speed open circuit wind tunnel has been designed, manufactured and constructed at the
Mechanical Engineering Department at Baghdad University - College of Engineering. The work is one of
the pioneer projects adapted by the R & D Office at the Iraqi MOHESR. The present paper describes the
first part of the work; that is the design calculations, simulation and construction. It will be followed by a
second part that describes testing and calibration of the tunnel. The proposed wind tunnel has a test
section with cross sectional area of (0.7 x 0.7 m2) and length of (1.5 m). The maximum speed is about (70
m/s) with empty test section. The contraction ratio is (8.16). Three screens are used to minimize flow

Human beings have an innate and natural aim to achieve their self-interests and to show their ability to overcome challenges in a better way, therefore the move towards self determination is expressed by intrinsic motivation. The desire of absorbing in this task is to enjoy the task in it self and benefitting from it such a motivation is the desire rooted in human nature to judge and choose in which individual is conscious in his self, abilities and adequacy that help him in control the different situations of life passed by him. His choices and actions are voluntary and non-restricted to intervention or external control because control is inner and subjective, while his behavior is self-regulated with the feeling of

Using a mathematical model to simulate the interaction between prey and predator was suggested and researched. It was believed that the model would entail predator cannibalism and constant refuge in the predator population, while the prey population would experience predation fear and need for a predator-dependent refuge. This study aimed to examine the proposed model's long-term behavior and explore the effects of the model's key parameters. The model's solution was demonstrated to be limited and positive. All potential equilibrium points' existence and stability were tested. When possible, the appropriate Lyapunov function was utilized to demonstrate the equilibrium points' overall stability. The system's persistence requirements were spe
