In this research, embedding process is done on RGB image by comparing pixel by pixel to embed watermark. This algorithm depends on embedding style that are less effect on RGB image through analyzing watermark and finding the most dominant bit and with using new techniques depends on probability principle for embedding process to ensure less change ratio on original image to provide high quality image. Image watermark are added to all parts of image to make watermark more robust. This algorithm give an excellent result when watermark with less thickness edge and it provides high security because of several reasons first it depends on probability embedding style; second, it uses keys to select compared pixels; third it gives less effect on original image. Therefore, the attacker didn’t notice that there is watermark.

A standard, inexpensive open circuit wind tunnel was built to understand and study some applications that related with atmospheric boundary layers, pollution and generate electricity by wind. Its operation, efficiency, and features were tested. Air speed measurements were taken for both sides: inside and outside the tunnel and the air temperatures were measured, as well. Obstacles were put inside the tunnel to observe the air flow patterns. The relationship between the input voltage of fan and the speed of air inside the tunnel was established to calibrate different types of anemometers. Mach number was calculated for the tunnel which was about 0.02. Bernoulli principle was used to find air speed at the end of diffuser section. It was 1.38 m/s, that means this value was close to the observation value (1.5 m/s).

The world that surrounds us is filled with toxic substances and there are many of them naturally entirely independent of human activity, perhaps affected humans in ancient times when air pollution from fires lit in the few caves ventilation. Ever since humans began polluting in a lot of areas on the surface of the earth. Until recently, the local environmental and secondary pollution problems due to the ground's ability to absorb and purify the trace amounts of contaminants property. Manufacturing in the community and the introduction of motor vehicles of the contributing factors to the increasing problem of air pollution. At this time it is necessary to find ways to clean the air. The main air pollutants found in most urban areas, carbon monoxide, and nitrogen oxides and sulfur oxides, hydrocarbons and particulates (both solid and liquid) spread of these pollutants in the atmosphere all over the world in high enough concentrations to cause serious health problems gradually. In addition, it may be natural or caused by human activity so that the amount accounted for in the Arab world and 40% can be classified as pollutants to the initial secondary pollutants and contaminants. Usually primary pollutants are substances that are issued directly from one of the processes such as scattered ash from a volcanic eruption or the first gas carbon dioxide emitted from car exhaust or carbon dioxide from factory chimneys. Therefore, this study will focus on the relationship between

Graphene oxide which one of carbon nano structures: its single layer (SLGO) or a few layers (FLGO, no more than ten layers) of graphite, these sheets contain many functional groups, epoxy, carboxy, carbonyl and hydroxyl groups. Graphene oxide (FLGO), grapheme oxide-poly aniline and grapheme oxide-thiocarbohydrazide have been prepared and characterized by infra red spectra, X-ray diffraction and atomic force microscope. The addition of these materials by chemical reaction to the grapheme oxide nano particles have an important role in the electrical properties of this nanomaterial which is insulator, so graphene oxide was chosen in this research for studying the electrical properties of functionalized graphene oxide. Through LCR measurements we noticed increasing in the conductivity.

In this work, a method for the simultaneous spectrophotometric determination of zinc which was precipitated into deionized water that is in a commercial distribution systems PVC pipe, is proposed using UV-VIS Spectrophotometer. The method based on the reaction between the analytes Zn2+ and 2-carboxy-2-hyroxy-5-sulfoformazylbenze (Zincon) at an absorption maximum of 620nm at pH 9-10. This ligand is selective reagent. Since the complex is colored (blue), its stoichiometry can be established using visible spectrometry to measure the absorbance of solutions of known composition. The stoichiometry of the complex was determined by Job’s method and molar ratio method and found to be 1:2 (M: L). A series of synthetic solution containing different concentrations of zinc were used to check the prediction ability of the complexation. Water quality samples collected a 100cm PVC system of drinking water in three sizes from different country full with deionized water for different time.

As a complement to the former work of ????????-regular modules, in this paper along the lines of ????-regular modules due to Zelmanowitz, we improve the study of the endomorphism ring of ????-regular modules to ????????-regular modules. We give a sufficient condition on ????????-regular module ???? such that ????=????????????(????) is ????-regular ring and we prove that ????-module ???? is ????????-regular if and only if ????=????????????(????) is ????-regular ring in case that ???? is a projective finitely power generated ????-module. Also we show that for a ????????-regular ????-module ????, the center of ????=????????????(????), ????????????(????), is ????-regular ring. Even further if ???? is a ????????-regular ????-module then ????/????????????(????) is dense in ????????????(????).

Simple, rapid and sensitive flame atomic emission spectrophotometric method is described for the determination of trace amount of Metronidazole Benzoate in pure and its pharmaceutical preparations. The method was based on the oxidation of Metronidazole Benzoate by potassium permanganate in alkaline solution to form an intense yellow soluble product and the intensity emission measured of potassium at emission line 766 nm using flame emission spectrophotometer. Beer's law is obeyed over the concentration range of 5-45 μg/mL, and relative standard deviation RSD% were (1.645, 1.705), and detection limits were (1.844 , 1.635 μg/mL), for tablets and injections respectively. The proposed method has been successfully applied for the determination of Metronidazole Benzoate in bulk drug and pharmaceutical formulations. The common excipients and additives did not interfere in these method.

Cystic Echinococcosis (CE) or Hydatidosis, a parasitic disease that caused by larvae of Echinococcus granulosus, is an important zoonosis endemic in large parts of the world and Iraq. Diagnosis of hydatidosis antibodies is based on immunodiagnostic methods (ELISA), along with radiological and ultrasound examinations, when treatment by chemotherapy and surgery.The objectives of the present study were to determine a specific antigen concentration -based ELISA technique for diagnosis of hydatidosis and compare it before and after surgery A total sample of 102 Iraqi subject from different hospitals were included in this study. They were distributed as 52 patients (43 females and 9 males, included the same group of patients study after 3-7 days surgery to remove hydatid cyst), and 50 persons healthy controls. Hyper immune-serum was raised against hydatid cyst fluid in rabbits. Anti-hydatid cyst IgG was purified by Ione exchange chromatography. The results show that increased circulating hydatid cyst antigen concentration before surgery 38.7μg/ml than antigen concentration after surgical removal hydatid cyst 25.7 μg/ml the difference was significant at P≤0.01. In the present study, the presence of circulating antigens in sera of hydatidosis patients by indirect ELISA[new kit] was detected hydatid cyst antigen in preoperative sera in 50 out of 52 (96.15%), the test demonstrated antigen in 48 out of 52(92.30%) postoperative sera.

Numerous studies reported that symptomatic and asymptomatic bacteriuria is common in pregnant women. It may be related with serious obstetric complications. Therefore, the current study aimed to finding the prevalence of bacteriuria, bacterial profile and antibiotic resistance pattern of uropathogens. A total of 140 pregnant women were participated in this study from November 2015 to February 2016. The result revealed that the overall prevalence of bacteriuria was 47.14%, while prevalence of bacteriuria with symptomatic and asymptomatic were (43.28%) and (50.68%) respectively, which shows that there was not statistically significant differences between the two studied groups. The pregnant women with age between 15-19 years had the highest rate of bacteriuria (85.71%). The high frequent bacteriuria also was found in third trimester (56.25%) compared with first (30.43%) and second (43.40%). Escherichia coli (22.73%), Staphylococcus aureus (19.7%), and Staphylococcus epidermidis (10.61%) were the predominant isolated uropathogens. Antibacterial susceptibility test was achieved for all isolated strains by the Kirby-Bauer’s disk-diffusion method. Our result revealed that more than 90% of the isolates were resistant to cephalexin and amoxicillin/clavulanic acid. However amikacin was the most potent of all studied antibiotic 77.3% of uropathogens were sensitive to it. The resistance rates to ≥3 antimicrobial agents was 98.5% while, only 1.5% were resist to all antimicrobial tested.
