The Effect of Oral Contraceptive Pill on Cortical Thickness and Bone Mineral Density of The Mandibular Mental and Gonial Regions in Premenopausal Females Using Spiral Computed Tomography
...Show More Authors

Background: Prolonged use of low-dose estrogen ''20 micrograms or less" Combined oral contraceptive pill (that have estrogen and progesterone steroid hormone) had an effect on bone turnover .Bone mineral density is used in clinical medicine as an indirect indicator of osteoporosis and fracture risk. The aim of the study: The aim of this study was to investigate the effect of low dose oral contraceptive pill on the cortical thickness (in millimeter) and bone mineral density at the mandibular cortex of mental and gonial regions in Hounsfield unit(HU) using spiral computed tomography. Material and method: This prospective study was conducted on computed tomographic image of 100 women aged between (20-40) years .The collected sample includes patients attended for different diagnostic purposes to AL-Shaheed Al-Seder Teaching General Hospital of Al-Najaf AL-Ashraf from Julay, 2015 to May 2016.Data were grouped into two categories :group (1)control group (don't use combined oral contraceptive pill) (n=50);group(2)women taking low dose(20microgram) combined oral contraceptive pill for more than 2 years,(n=50).Cortical thickness measured in millimeter and Bone Mineral Density measured in Hounsfield unit both in mental foramen and gonial angle regions .Physical activity number of parity type of lactation were documented by questionnaire. Result: There was a statically significant difference; in cortical thickness p=0.037 and bone mineral density P=0.007 in mental area between the two groups ;the lowest mean in group (2)and highest mean in group(1) . After adjustment for age ,number of parity, and physical activity measurement scores ,there was a significant difference p=0.001 in mean of bone mineral density and p=0.065 for cortical thickness of gonial angle between the two groups ;the highest mean in group (1) and lowest mean in group (2). CONCLUSION: Computed tomography is a good diagnostic method to measure the value of cortical thickness and bone mineral density simultaneously in mental and gonial region of the mandible in premenopausal female using low dose combined oral contraceptive pill which have small effect on bone ;depended on the woman's age and the duration of using the pill ;that did not appear until about two years of use.

Analysis of Magnetorheological Normally Close Directional Control Valve: Magnetorheological normally close directional control valve
...Show More Authors

This valve is intended for use in valves for steering movement, using the qualities of the Magneto-rheological (MR) fluid to regulate the fluid, direct contact without the utilization of moving parts like a spool, a connection between electric flux, and fluid power was made, The simulation was done to employ the" finite element method of magnetism (FEMM)" to arrive at the best design. This software is used for magnetic resonance valve finite element analysis. The valve's best performance was obtained by using a closed directional control valve in the normal state normally closed (NC) MR valve, with simulation results revealing the optimum magnetic flux density in the absence of a current and the shedding condition, as well as the optimum

Non-Destructive Testing of Carbon Fiber Reinforced Magnetic Reactive Powder Concrete Containing Nano Silica
...Show More Authors

This study involves the design of 24 mixtures of fiber reinforced magnetic reactive powder concrete containing nano Silica. Tap water has been used in mixing 12 of these mixtures, while the other 12 have been mixed using magnetic water. Nano Silica (NS) with ratios (1, 1.5, 2, 2.5 and 3) % were used. The results showed that the mixture containing 2.5%NS gives the highest compressive strength at age 7 days. Many different other tests were carried out, the results showed that the fiber reinforced magnetic reactive powder concrete containing 2.5% NS (FRMRPCCNS)  has the higher bulk density, dynamic modulus of elasticity, ultrasonic pulse velocity  electrical resistivity and lesser absorption than fiber reinforced

Field Programmable Gate Array (FPGA) Model of Intelligent Traffic Light System with Saving Power
...Show More Authors

In this paper, a FPGA model of intelligent traffic light system with power saving was built. The intelligent traffic light system consists of sensors placed on the side's ends of the intersection to sense the presence or absence of vehicles. This system reduces the waiting time when the traffic light is red, through the transition from traffic light state to the other state, when the first state spends a lot of time, because there are no more vehicles. The proposed system is built using VHDL, simulated using Xilinx ISE 9.2i package, and implemented using Spartan-3A XC3S700A FPGA kit. Implementation and Simulation behavioral model results show that the proposed intelligent traffic light system model satisfies the specified operational req

Marijuana THC treatment led to decreased metabolic functions of Staphylococcal enterotoxin B-activated lymphocytes
...Show More Authors
Abstract<p>Studies from our laboratory have shown that Δ9-Tetrahydrocannabinol (THC), an ingredient found in marijuana plant Cannabis sativa, can attenuate acute lung injury induced by Staphylococcus enterotoxin B (SEB). In the current study, we investigated the role of THC on the metabolism of SEB-activated lymphocytes. To this end, we determined metabolic potential of SEB-activated lymphocytes treated with vehicle or THC by performing the Cell Mito Stress Test. The oxygen consumption rate (OCR) in THC-treated cells was decreased when compared to vehicle-treated group whereas the extracellular acidification rate (ECAR) was similar in both the groups. Specifically, electron transport chain inhi</p> ... Show More
