The current study was conducted to detect the bacteria that causes skin infections in Mosul city and to study its resistance pattern to different antibiotics. For this purpose, 30 swab samples were collected from different skin infections from patients referred to the dermatology consultations of Al-Salam Teaching Hospital and Mosul General Hospital in Mosul city. The results of isolation and diagnosis showed that (20) samples, 66.6% of the total samples were positive for bacterial culture. (56.5%) of isolated bacteria were Gram-negative and 43.5% belonged to Gram-positive bacteria. The isolation percentage for Staphylococcus aureus and Sphingomonas paucimobillis were (17.3%) each, Pantoea spp. (13%), and all three species belonging to the genus Kocuria and Klebsiella pneumonia was 8.6% each, while Acinetobacter baumannii , Brevundimonas diminuta , Enterobacter aerogenes , and Pseudomonas luteola were isolated by (4.3%) each. The results for antibiotic sensitivity showed the prevalence of multidrug resistance (MDR) phenomenon in all isolates, and the isolates showed a clear variation in their resistance to each antibiotic. The highest percentage of resistance towards antibiotics were (69.5%) and (60.8%) against the Oxacillin and Penicillin, respectively. All isolates were sensitive towards levofloxacin, which makes it a suitable treatment option for infections associated with the bacteria understudy.

In this work, thin-film solar cells based on Cadmium Selenide (CdSe) film were used, due to the low manufacturing cost and superior electronic properties, and this type of cell also achieves appropriate efficiency. The current work will focus on investigating the effect of the thickness and carrier concentration of the active layers in the cell, and the thickness of the window on the performance of the proposed solar cell, using the one-dimension solar cells capacitance simulation SCAPS-1D computer program. The proposed structure of this cell consists of ITO/n-CdSe/p-CdSe/Pt, where ITO was used as a window layer, n-CdSe as a buffer layer, p-CdSe as an absorber layer, and platinum Pt as a back conductive electrode. The results revealed that the cell performed best at thicknesses of 5000 and 100nm for the absorber and buffer layers, respectively, and with carrier concentrations of 10 16 and 10 17 cm -3 for the same layers. The optimal window layer thickness is 100nm. These variables yield open circuit voltage (V OC ), short circuit current density (J SC ), fill factor (FF) of 1.0845 V, 20.87 mA/cm 2 , 88.02% respectively, while the conversion efficiency of cell (Eff.) was obtained, which is 19.92%.

A simple spectrophotometric method for the determination of doxycycline in aqueous medium using oxidative coupling reaction has been described. The method was based on the reaction of doxycycline with 4-aminoantipyrene (4-AAP) which gives soluble and stable red colored product that gives the highest absorption at the wavelength 515 nm, and the linearity of Beer's law was in the concentration range from 5 to 110 µg/ml, and the value of the determination coefficient for the standard curve was 0.9995, which statistically indicates that it has excellent linear characteristics. The molar absorptivity was calculated and found to be 1.387x10 3 l.mol -1 .cm -1 . Sandell's sensitivity value, the Limit of detection (LOD), and limit of quantitation (LOQ) were calculated and equal to 0.3334 μg/cm 2 , 0.114 and 0.38 µg/ml respectively the method was successfully applied for the determination of doxycycline in its pharmaceutical preparation.

One of the most important diagnostic tools for a better understanding of actual systems is the spectroscopic examination of the physical properties of plasma and other bright sources. Atomic transitions of optical wavelengths are frequently used in a range of plasma devices as indicators of plasma characteristics like temperature and density. The design and construction of an effective spectrophotometer were motivated by the requirements of our ongoing plasma physics research. One of the most crucial methods for figuring out the density and temperature of electrons is the optical spectroscopic emission method. This study focused on the design and production of a low-cost Cherny-Turner spectrometer that could be produced locally. Using a manual micrometer, the slitter's exact movement is managed. Two quartz concave mirrors, one with a focal length of 15.375 cm and the other with a focal length of 16.825 cm, were employed. The spherical aberration was then treated by lowering the angle of incidence and angle of diffraction as much as feasible. The spectrometer's light input was focused, and the mirror positions were calibrated. The positions of the mirrors were calibrated with the diffraction grating to the location of the camera, first manually using a red laser light with a wavelength (650nm), and then using a CCD camera to locate the final image. With the movement of the diffraction grating to scan the wavelengths and analyze the light to its original components.

The research discusses the use of flashes of ultraviolet-C rays in inducing resistance against viral pathogens and the possibility of its employment in covered houses or garden nurseries. A number of tomato and tobacco plants of type Nicotiana tabacum , uder protected cultivation conditions, were exposed to UV-C rays at wavelengths 200-280 nm using an electronic LED lamp, for 5 and 10 minutes, all plants were inoculated 48 hours after the last exposure to UV rays. The number and size of local lesions were calculated on the leaves of inoculated tobacco plants, as well as monitoring the development of symptoms on tomato plants inoculated with the virus for 12 days of inoculation, and the virus concentration was estimated based on the amount of absorbance at 405 nm by ELISA test. The results indicated that the ultraviolet rays used enhanced the plant's resistance to viral infection through a noticeable increase in the enzyme peroxidase, as it reached (59220 nanometers) in the treated plants compared to the untreated plants that were (28,016 nanometers). The irradiation for the first five minutes had a higher effect than the longer irradiation that lasted for ten minutes, in addition to that the irradiation for intermittent periods and for a short period was better than the continuous exposure for one time. It was found that the leaves far from the radiation exposure area acquired an inducible character of resistance against the pathogen.

The bipolar region is one of the most important factors in determining the effectiveness of a magnetic lens. Regarding the focus and optical qualities of the display devices, the optimal position of the polepiece and the most significant aspect of the magnetic electron lenses were the iron shrouds, where the magnetic field increases smoothly and uniformly with the highest possible value and has just one peak. The goal of this study is to determine the position of the shroud tip relative to the axial axis (Z), where the tip of the polepiece is located at (Z = 0 mm). In practice, it has been seen that the optical properties of electron lenses have improved when the position of the polepiece iron shroud tip is separated by a distance of 180 mm. By extending the distance between the iron shroud and the polepiece face in the opposite direction of the coil, by removing or reducing magnetic flux leakage, it is possible to increase its performance. The axial magnetic field will then rise within the lens in a direction that prevents it from being lost. In this work, the FEMM and MELOP programs were used to investigate the lens' performance, axial magnetic field, and focal optical characteristics.

The current study included qualitative diagnosis and quantitative estimation of some active compounds in two types of weeds, namely wild mustard Hordeum sp. and wild barley Brassica sp. The results showed that these plants contained several chemical compounds that were diagnosed as phenolic acids. Wild mustard contained three chemical compounds, namely: Galic acid, Resorsenol, Vanillin While wild barley contained four compounds, namely: Galic acid, Resorsenol, Vanillin benzoic acid. The results of quantitative estimation also showed variation in the concentration of these compounds in the extracts of these weed residues.
