The current study was made during the period from July to November 2020. The infestation with head lice was searched for residents of Kirkuk city, and a random samples (1988 cases) were collected from city residents and check up their scalps to detect the head lice infestation. This study aims to determinate the prevalence of head lice infestation in different regions of Kirkuk city and to demonstrate the role of some epidemiological factors on the infestation as age, gender, nature of hair tissue, hair length, hair density. The current study showed the head lice infestation reached 117 cases with a total prevalence of infestation 5.88%. These results come from a clinical study that made on 1988 people from a variety of age groups, society, social-economic and cultural groups. The highest prevalence of infected was recorded (15.11%) for the age group 6-12 years, while the lowest prevalence of infected was for the age group 46-80 years (0.42%). The present research concluded that the infestation was higher in female than male (9.35, 2.10%, respectively). The highest prevalence of infected was in straight hair (3.40 and 11.76%) for both male and female (respectively), and the lowest prevalence of infestation was for curly hair (2.30%) in female, while the infestation for curly hair in male are not recorded. The results also showed the highest prevalence of infestation was in long hair (10.79 and 12.16%) than in short hair (0.63 and 3.63%) for both male and female (respectively). The highest prevalence of infestation was also recorded for high dense hair (3.13 and 12.63%) compared with low dense hair (0.66 and 1.65%) for both male and female (respectively).

The current study aimed to investigate the effectiveness of aqueous Clove extract and detect its minimum inhibitory concentration .This work was conducted at Azadi Teaching Hospital from a total of 56 samples taken from patients having burn infection using cotton swabs, and samples were cultivated in MacConkey and Nutrient agar and incubated inside the incubator for 24 hours. After incubation, samples were diagnosed by the Api20E system. Where 43 isolates were obtained from P. aeruginosa, 9 isolates from E. coli, 4 isolates from Klebsiella and 3 isolates of Staph. aureus.
The cold aqueous extraction method of Syzygium aromaticum was used and the minimum inhibitory concentration (MIC) was measured after culturing the bacteria in a nutrient broth medium containing known concentrations of the extract. And the susceptibility of the bacteria to a group of common antibiotics has been determined.
The results showed that 72.8% of the burn infection were caused by P. aeruginosa, and that the (MIC) value ranged between (0.01-0.1 mg / ml). And that the bacteria showed multi resistance to antibiotics, and high sensitivity to Nitrofurantoin.

Staphylococci spp ubiquitous, including a different species as normal flora. The most virulent and resistant to antibiotic are Staphylococcus aureus and mutans, species which colonizes epithelial surfaces and causes dangerous humans infections. The objectives of this study is studying and Using the agar agar weal diffusion process, researchers tested the The degree of susceptibility of bacteria from one type of plant extract to another varies for six different concentrations using several methods (50, 100, 200, 300, 400, 500 mg/ml) of each Aqueous and alcoholic plant extracted were used then evaluated. The alcoholic Ziziphus In this study, we see that the strongest activity of the extract against the tested bacterium Ziziphus. this analysis. Turmeric, alcoholic, and aqueous extracts, on the other hand, had comparable antimicrobial activity but at higher concentrations. However, against S. aureus and S. mutans, the aqueous extract of cuminum cyminum had no inhibitory action. The S. aureus isolates seemed to be resistant to the extracts of Ziziphus and Tumeric. The S. mutans isolate, on the other hand, was more susceptible to cuminum cyminum, but only at low concentrations

Adenosine is a nucleoside which occurs naturally in a diverse forms in all cells of the body and in most biological fluids. Under basal conditions, the extracellular adenosine concentration is maintained within certain limits. Dipyridamol inhibits adenosine reuptake by erythrocytes, endothelial cells and platelet increasing plasma levels of adenosine Aims: study the effects of adenosine and dipyridamole on serum levels of serum urea, creatinine, alkaline phosphatase(ALP), lactate dehydrogenase (LDH), Aspartate Aminotransferase (GOT), and Alanine Aminotransferase (GPT).

This study aims to investigate the effect of compounds extracted from pomegranate peels and green tea on some biochemical variables in the serum of domestic male rabbits with recently myocardial infarction.
The study was conducted in the Animal House of the College of Veterinary Medicine. 24 male rabbits were used, with an average of weights ranging between 1800 - 2000 grams, which were divided into three groups (8 / group). The first group was fed a standard diet as a control group and the second and third group fed a standard diet added to it Cholesterol by 1%. After 45 days, the second and third group animals were dosed, in which the myocardial infarction developed the extracted compounds, and the myeloperoxidase enzyme activity and the level of troponin, potassium, and magnesium were measured.
Blood samples were collected from the control groups, the second and the third in which the disease was developed, and after 21 days the samples were collected from the second and third groups after treatment with the extracted compounds. The induction of myocardial infarction led to a significant increase in the activity of myeloperoxidase enzyme MPO and the level of troponin, potassium and magnesium, with a probability level of p≤0.01.
In comparison with control, there was a significant decrease in myeloperoxidase activity and potassium troponin level for groups in which the extracted compounds were dosed after disease onset, and with a probability p≤0.01 compared to the affected groups

A wonderful event had taken place in the Gurgayi Fatah Village (5 Km to the north of Chamchamal Town), when gas and water are blowouts from a shallow drilled water well. Scientists and people hurry to view and investigate this phenomenon. The current study attempts to interoperate the factors behind gushing water and gas. Samples of gas and water were analyzed for gas composition and δ 13CH4 isotope, major and heavy metals, and environmental isotopes δ18O and δ2H. The results of the hydrochemical analysis showed that Ca2+ and SO42- are the dominant ions and the concentrations of heavy metals are below the detection limit. The values of δ18O and δ2H isotopes were -6.25 and -30.85 respectively indicating that the recharge of groundwater is recent. The dominant gas composition is Methane CH4 with 84.5% volume per unit volume, while it characterizes by elevated hydrogen sulfide with a value of 17700 ppm.
The study revealed that the drilled water belongs to the first system (gravity hydrodynamic systems; where the water moves by the action of gravity from sites of high potential, and the major faults and fractures connecting the deep aquifers to the shallower. The high-pressure phenomenon is well known in Fatha Formation even more notable some oil wells along the foothill’s zones.

Gypsum products are one of the most widely used materials in the industry. The wide use of gypsum as a building material over a very long period of time. A number of manufacturers introduce different professional quarries, but their physical and chemical properties were still questionable. Five gypsum samples were taken for chemical and physical analysis. Chemical analysis shows that gypsum are of high purity, more than 95.25% with varying amount of impurities; SiO2 (1.49-1.87) %, Na2O (0.17-1.00) %, MgO (0.03-0.13) % Al2O3 (0.06-0.23) % and Fe2O3 (0.05-0.09) %, .This can be used for Plaster of Paris without any purification of gypsum. The (SO3 and CaO) % shows that all studied samples are suitable for gypsum production as the final coating and building gypsum. The physical analysis shows that the colors of gypsum samples are suitable for building, Plaster of Paris, final coating and Juss according to the color chart of minerals and to Iraqi standard specification. The fineness percentage is less than 8%. Thus the specifications of all samples are agreements to standard specifications for building gypsums. In terms of setting time, the sample 1 and 2 are suitable for building gypsum and plaster of Paris and classified as Borax. However, samples 3, 4, and 5 are suitable for anhydrous calcined gypsum – final coat and classified as Knee cement. Moreover, the setting time for all the samples increased with the increase of the water powder ratio.

In this study, the water table in reservoirs in the Al-Alam area was studied for the year 2019. The water table was taken for 104 wells that covered the study area, except for the region near the Hemrin anticline, because it was impossible to reach for safety reasons. It was found that the higher water table North Study area near the Hemrin anticline and the levels decreased towards Al-Shari playa. A simulation of the aquifer was made after the introduction of the water table, the hydraulic properties of the area, and the depth of the reservoir. Three hypotheses were made to simulate the aquifer within one year by placing several virtual wells with constant drainage and the number of fixed operating hours during the year. to know the amount of water that leads to the depletion of the aquifer and the safe drilling distance of the aquifer. For the aquifer not to reach the stage of over-pumping and depletion, as several hypothetical wells have been placed in a manner that approximates the reality of the study area, Through a questionnaire on the number of working wells and relied upon in the study area, they were from about (250-350) wells. (200 wells, 300 wells, 400 wells) with constant discharge and operating hours during the year. As the well was operated according to the policies set by the Ministry of Agriculture with a discharge of (7 liters/second) for a period of (8 hours/day) for a period of (22.5 days/month), which is equivalent to (270 days/year) that is, at the disposal of (54432 m3 / year) for each A presumed well, to know the impact of the reservoir, and It was found that drilling 200 wells with a distance of 1 km2 between one well and another is considered safe and that drilling 300 wells or 400 wells in the study area leads to the depletion of the aquifer.

In this study, thin films of copper oxide (CuO) prepared using a chemical bath deposition (CBD) method on glass substrate. Aqueous copper sulfate (CuSo4.5H2O) used to obtain the required thin films and in concentration 0.1M. The films prepared during different deposition times (1, 4 and 8) days at room temperature. The XRD studies showed that the thin film prepared at deposition time (8 days) has polycrystalline structure (monoclinic structure). Morphological studies by using AFM measurements and topographical studies by using SEM measurements revealed that the surfaces of the prepared thin films show better uniformity when increasing deposition time from 1 day to 8 days, where the average diameter, roughness rate and root mean square (RMS) decreased with increasing deposition time

In this article, a theoretical analysis to measure the band composition, optical properties and density of states (DOS) of rutile titanium dioxide was conducted via the castep simulation program. Calculations of the first principles were carried out using the super cell (1x1x1) process. The first computation of 〖TiO〗_2 concepts was studied by density functional theory (DFT) with a generalized gradient approximation from Perdew-Wang's 1991 (GGA-PW91), local density approximation (LDA) for exchange-correlation energy functional, and (LDA)+U method, implementation of coulomb interactions btween U_d of (〖Ti〗_3d) atom and U_p of (O_2p ) atom.All experimental values are agreed with our results. The results for LDA and GGA-Pw91 indicated weaknesses in the estimation and far from the experimental results for the properties of the 〖TiO〗_2 rutile under analysis, except for the energy band difference, although the estimation data (LDA) + U was in accordance with the experimental values. The optical properties of rutile 〖TiO〗_2 was obtained using several methods of exchange correlations, well in accordance with experimental findings and other theoretical evidence.

Iron oxide nanoparticles (Fe2O3) were prepared by pulsed Nd-YAG laser ablation technology for a target of iron oxide in ultra-pure water with a constant number of pulses (250) with different ablation energies (400, 500, 600, 700 and 800) mJ and formed a colloidal solution for each energy. Optical properties were calculated and changing the energy value on the preparation of iron nanoparticles was shown, and the value of energy gap varies from (2.88-3.04) eV according to the change in the ablation energy

When the multicollinearity exists in linear regression model, the result of the Restricted Least Square estimator (RLS) is unstable. So that, more researchers proposed the restricted biased estimators to improve the efficiency of RLS estimator. In this paper, Some of biased restricted estimators have been introduced to study the performance of them. The simulation study has been given to compare these estimators. According to simulation study, we found that, the shrinkage restricted ridge regression (SRRE) estimator which proposed by Baber and Mustafa [1], has good properties comparing with other restricted estimators that given in this study. A Numerical example has been considered to illustrate the performance of these estimators
