The means were: IL-17 A (79.29 pg\ml),( 18.72 pg\ml ) and IL-17F(226.4 pg\ml ),( 29.09 pg\ml ) respectively. Also the serum levels of p ANCA and c ANCA were determined using Enzyme-linked immunosorbent assay ELISA technique for quantitative determination of pANCA and c ANCA concentrations in human serum. There was a significant difference in levels of perinuclear antineutrophil cytoplasmic antibodies (pANCA) and cytoplasmic antineutrophil cytoplasmic antibodies(c ANCA ) with p-value(<0.05), the means were: pANCA ( 60.93 ng\ml), (10.31ng\ml), and c ANCA (35.78 ng\ml), (8.341ng\ml) respectively.

The present study attempts to determine the best planting date and concentration of spraying with gibberellin to improve the performance and quality of maize's growth and yield traits. This investigation was carried out in the district of Tarmiyah - Baghdad governorate to study the effect of planting dates and spraying with gibberellin on the growth and yield of corn (Zea mays L.) of the variety (Buhooth 106) for the summer farming season in 2020. The experiment was applied according to the Randomized Complete Block Design (R.C.B.D) with the split plot system, using four planting dates (1/7, 10/7, 21/7, and 28/7/2020) and four concentrations of gibberellin (0, 150, 250, and 350 mg. Liter-1). The best significant superior value was recorded on 21/7/2020 by interference with a concentration of 350 mg. L-1 in most of the traits, as it was recorded (221.14 cm) for the height of the plant, (45.39%) for chlorophyll, (300.33 g) for the weight of 1000 kernel, (13.54 tons. h-1) for the grain yield, (18.84 rows. ear -1) for the number of rows in ear, (14.27%) for protein, and (5.22%) for oil. Whereas it significantly exceeded the date 28/7/2020 by an interference with the concentration of 350 mg. L-1 in the two traits of the number of grains in the row and the gibberellin content in leaves, its values were (44.62 grain. row-1 and 46.09 μmol) respectively. Accordingly, it is concluded that the optimal intervention mixture is determined to be an intrusion with a concentration of 350 mg. L-1 at the date of 21/7/2020 was included in the majority of the traits tested

Staphylococcus aureus is naturally colonizing the skin and the naris of healthy people and Staphylococcus aureus exhibits different surface factors of the cell, which play a role in their virulence. This study explained the increasing β-lactamase secrtion by Methicillin Resistant. S. aureus primarily decreases the antibiotic affect, and Methicillin Resistant. S. aureus (MRSA) has increasingly become the most prevalent resistance pathogens in the world. This study stated that Quinolones function antibacterial by inhibiting bacterial topoisomerases, important in the removal of DNA super-coiling and separation of concatenated DNA-strands.

Background: Wound infections are considered a major problem in the field of surgery for a long time, with growing bacterial resistance to drugs that were once considered the first line of treatment for post-operative wound infections, according to data spanning two years. The objectives of this research were to evaluate the prevalence of bacteriological profiles that cause surgical wound infections and the antimicrobial susceptibility patterns between outpatient clinics at Azadi teaching hospital in Duhok, Iraq. Methods: 165 wound swab samples were collected from surgical wound infections and tested on Blood agar, MacConkey agar, and Nutrient agar, then identified using different cultures and standard biochemical tests. On Muller Hinton Agar, all of the isolates were tested for antimicrobial susceptibility using the disk diffusion technique, as defined by the Clinical and Laboratory Standards Institute (CLSI). Results: 90 (54.5%) of the 165 surgical wound swab samples cultured had a positive bacterial culture, with Klebsiella pneumoniae 25 samples (27.8%) being the most common pathogen, followed by Staphylococcus aureus (20 samples). Some gram-negative bacteria such as Pseudomonas aeruginosa (14 samples), Escherichia coli (13 samples), Proteus mirabilis (7 samples), and Enterobacter cloacae were also isolated (2 samples). Except for amikacin, imipenem, and ciprofloxacin, the majority of pathogens isolated demonstrated greater resistance to most other antibiotics. Conclusion: In this research, the incidence of surgical wound infection was found to be higher in the study region. Klebsiella pneumoniae was isolated as the most common causative agent, with multi-drug resistance and antibiotype patterns that varied

The current study is conducted to evaluate the efficiency of the drinking water pu-rification plant supplying for some areas north of Tikrit. The study samples were taken monthly, including a sample from the river outlet of raw water, a sample from the sedi-mentation basin, and the third sample from the drinking water line, starting from August of 2020 until March 2021. The study included, firstly, measuring some environmental factors, including (turbidity, pH, dissolved oxygen, Biochemical oxygen demand , calci-um hardness, magnesium hardness , chloride ion) and secondly, microbial factors (total aerobic plate count, total coliform). The study has recorded high values of turbidity in the winter season, reaching (162.4) nephelometric turbidity unit, while the pH values were tending to be basicity, as their levels ranged between (8.3-7.1). As for the dissolved oxy-gen concentration, it was high in the spring season, reaching (9) mg / Liter and the con-centration of the biochemical oxygen demand was high in the summer season due to the high temperatures, as its concentration reached (4. 3) mg / liter. The chloride ion concen-tration was conformity with compliance with international standards, it ranged between (55.6-32.7) mg / liter. The microbial study, it was found that the water is very polluted, especially in the spring season, as the values of the total number of aerobic bacteria ranged between (17.6-3) × 103 cells / ml, while the values of the total number of coliform bacteria were between (4-4) cells / 100 ml.

Cs2TiBr6 is a promising material as an Absorber layer of Solar cell. Further studies showed that this compound is more stable, and possess an appropriate electrical and optical properties. The compound of (FTO/V2O5/Cs2TiBr6/CdTe) is simulated for the first time in this work by using the Solar Cell Capacitance Simulator (SCAPS-1D) program and the obtained transformation efficiency (η) was (10.09) with (0.5µm) of (Cs2TiBr6) thickness. The effect of (Cs2TiBr6) thickness was studied in this paper used different variations of absorber layer thickness (0.5 – 4.0 μm). Solar cell enhanced by absorber layer thickness showed (18.17 mA/cm2, 0.924V, and 86.58%) (Jsc, Voc, FF) respectively which led to increase of transformation efficiency (η) from (10.09 % to 14.55%).

In this research, a practical and theoretical study was conducted to evaluate the performance of parabolic trough collectors (PTCS) of length (3 m) and width (2.67 m) for three solar collectors connected in parallel, and the absorber tube is made of stainless steel with an internal and external diameter (0.028 m), (0.031 m), respectively. The absorber tube of length 11 m, was painted with un shiny black paint to increase the absorption of sunlight and reduces the thermal radiation. The working fluid is transferred through the receiver tube and located at the focus area of the three collectors. The collector width aperture width was 0.8 meters, and 2.40 meters length with rim angle of Ø = 90°, and concentration ratio of 8.02. The collector surface was covered with aluminum foil which is available in the local market (3M SA-85), which covers galvanized iron sheets with a thickness of 2 mm. A computer program in Fortran language was built to calculate the performance of the solar collector. Experimental results of the test showed that the performance factor of the solar collector is less than the typical type, where notes that there is a large deviation between the theoretical and experimental results, especially in the winter, where the deviation in the morning at ten o\'clock about 78%, while it was 5% at noon. The large deviation value mentioned resulting from the assumptions that have been developed to simplify the equations that were used in the theoretical side of research, also the reasons that the theoretical results are taken on the assumption that weather conditions are clear sky and that contrary to reality in the winter. ةThe best efficiency of the solar collector was between solar time (12:00) and time (1:00) at night for two seasons, and the obtained results showed that the increase of mass flow rate of fluid from the amount of (0.033) kg/sec to the amount of (0.066) kg/sec increases the efficiency of solar collector, but leads to reduce the temperature difference between the inlet and exit, as well as the results showed that an increase in solar flux increases the useful energy obtained from the solar collector

This note investigates modules having quasi-injective and duo submodules. We introduce a new generalization of C_1-module. The main method that was adopted in this generalization is how to obtain a submodule N in M having the characteristic Quasi-injective. We investigate the relationship between pseudo-injective module and Quasi-injective property of C_1-module. Finally, we introduce a new relationship between Quasi-injective submodule and anti-hopfian module.
