This study is carried out to investigate and evaluate the level of cultural and health awareness of workers in some restaurants in the city of Karbala. And the extent of their application of health conditions in preparing kebabs for consumers and its relationship to the microbial content .It was found through the questionnaire forms and the personal interviews that the health conditions weren’t applied, due to poor health awareness, and lack of knowledge of the factors of food contamination with microbes. Therefore, microbial contamination in the kebab was investigated during its manufacturing stages. The study included randomly selecting 10 restaurants in a center of the city centre and surrounding areas, the number of samples studied were 20 samples of minced meat and 20 samples of raw kebabs for the period from 1/7-28/7/2021 (total samples 160 ), the microbial tests included, total plate count (TPC) and total coliform bacteria (TC) and Staphylococcus aureus (SA), as well as Salmonella test. The result of this study showed that TPC, TC, SA ,in minced meat is 10.1 - 13.7 x 107 CFU / g, 11.9 - 15.1 x 105 CFU / g, 5.3 - 9.1 x 105 CFU / g, respectively. Salmonella test was negative in all samples. And in raw kebab were 11.2 - 15.2 x107 CFU / g, 12.6 - 16.9 x 105 CFU / g, 6.1 - 10.2 x 105 CFU / g, respectively. Salmonella test was positive in 16 samples in minced meat from 80 samples, during the study period (the Percentage of contamination was 20 %). And all of kebab’s meat were negative identified or did not contain E. coli, Staphylococcus aureus, and Salmonella , after the grilling process.When comparing these results with the microbial limits of the Iraqi standard (2006) , it was found that more than 70% of the samples contaminated exceeded the maximum limit. We also identified, through this study, the weakness of the cultural and health level of some restaurant workers with regard to preparing kebabs in the correct way.

In the current review, we explored the impact of Gum arabic (GA) against Bisphenol A (BPA)- prompted nephrotoxicity in male albino rats. Thirty-five adult male albino rats were divided into five groups: group (1) served as a control, group (2) rats received 8 mg/ kg of GA extract, group (3) received BPA 50 mg / kg b.wt. by oral gavage, group (4) consists of rats received first GA extract + BPA, and finally group (5) consists of rats received first BPA + GA extract. Urea, Creatinine, Superoxide dismutase (SOD) glutathione (GSH), and malondialdehyde (MDA) were assayed, in addition to histological study. The results of this study showed that there was a significant increase in the levels of all urea, Creatinine, and MDA, and a significant decrease in the levels of both GSH and SOD in the third group exposed to BPS, while there was a significant decrease in all of urea, Creatinine, and MDA, and a significant increase in the level of antioxidants GSH, SOD in the fourth and fifth groups Which was dosed with GA extract and BPS. Histopathological changes of kidney were observed in third group (treated with BPA) and fourth group (BPA + GA treated) as compared to control group. This study demonstrated the antioxidant effect of GA and against BPS -induced renal injury.

Bulk numbers are popular for countable dataries, such as inflated zero regression prototypes. Zero-truncation operations with zero truncation can be effective in elaborating problems with prototypes numbers of zeros, as the behaviour of zeros in the datarie s shown may elicit difficulties, when they are solved by zero-truncation operations on the databases. The different Poisson threshold prototypes that use are known as the smallest value that gives the shift of the distribution from the normal regression to the zero inflated regression. This research includes simulated experiments according to the difference in the sample size (n=20,50,100) and the initial values of the Polluted number (\lambda=1,2,3), inflation parameter (P=0.1,0.3) and (Maximum Likelihood Estimation (MLE), Method of Moment Estimation (MME)) for ZIP with (1000) iterations. The simulation results showed that the inflated zero parameter was affected with (sample size, the distribution parameter value and the initial value of the inflated zero parameter). Other estimation methods can be adopted, including Shrinkage Bayesian and Zero-Inflated Binomial regression models.

Compounds and polymers prepared were identified by using techniques (FT-IR and 1H-NMR), spectroscopy, and study physical properties of compounds and polymers, including (melting points, softening points), and solubility.

A mite allergy is an allergic response to mites which often inhabit damp and dark environments. Signs of mite allergy include rhinitis such as sneezing, runny nose and asthma such as wheezing and difficulty breathing. The study was purposed to a comparison of a few mite species that cause allergic asthma. The increasing prevalence of respiratory allergy especially dust mite allergy in Iraq has caused climate change. The study was aimed to investigate some immunological and hematological in the patient suffering from dust mite and storage mite allergy. Mite allergy was diagnosed by Skin-prick test, intradermal test, and particular amount of IgE level. Individuals (90) blood sample was collected from Specialized allergy center and private laboratories ; Included (60) samples [female (36) , male (24)] from patients suffering allergic asthma of House Dust Mites ,their ages are between (15-50) years and(30)samples [female(18),male (12)] from patients suffering allergic asthma of storage mite , their ages are between (20-45) years . The number of apparently healthy control was (30) [females (16) and males (14)] their ages are between (22- 45) years. The Immunological factors were studied including assessment of serum interleukin IL-4 level, and total of serum IgE level. About season (35.00%) of storage mites increased in autumn and (55.00%) of house dust mites increased in winter. The environmental factors play as a trigger factor for emergence of respiratory allergies in Iraq brought on by storage and house dust mites. The season is major role for increasing dust mite allergy has confirmed the importance in the research.

The electronic and optical characteristics of circumcoronene are significantly impacted by phosphorus doping. Improved stability, smaller energy gaps, and changed Fermi levels are some of the main results, which make these doped systems attractive options for use in energy devices, photonics, and nanoelectronics. Phosphorus doping significantly alters the chemical indices of circumcoronene, increasing its stability, reactivity, and suitability for uses requiring robust electron interaction. The design of nanoscale materials, including catalysts, sensors, and energy-storage devices, will be significantly impacted by these discoveries. The structures can be appropriate for applications that need absorption in the far-infrared or electronic devices with decreased optical loss by modifying the high-energy transitions with a considerable oscillator strength. The optical characteristics of circumcoronene are markedly altered by phosphorus doping, as seen by longer absorption wavelengths, lower transition energies, and weaker oscillators. Because of these changes, phosphorus-doped circumcoronene retains its adjustable electronic behavior for certain optoelectronic applications while being extremely versatile for usage in infrared photodetection, optical sensors, and energy storage.

The fifth generation (5G) of telecommunications has been a compelling subject for several academics in recent years. A patch antenna has recently been used for 5G technology, which demands a communication connection with a high data rate and low latency. This article proposes a high-gain slotted microstrip patch antenna for 5G applications at the resonant frequency of 38 GHz. Rogers RT5580 material, with a dielectric permittivity of 2.2 and a loss tangent of 0.009, has been used as a substrate for the antenna. The antenna in concern has a compact construction with dimensions of 8×5.2×0.324 mm³. The slotted antenna's dimensions are optimized with the CST Studio Suite software simulator. The proposed antenna design achieved a reflection coefficient of -49.9 dB, a gain of 9.233 dBi, and a wide operational bandwidth of 1.84 GHz, which is the main objective of this study. The suggested antenna also demonstrated favorable performance at 37 GHz and 39 GHz by changing the length of the radiation patch. In comparison to previous similar designs reported in the literature, the proposed antenna has significantly higher bandwidth, return loss, beam gain, and radiation efficiency; therefore, it is a viable alternative for 5G communication.

Spores of P. griseoroseum were gathered from the atmosphere, this facilitated the identification of the fungus by looking for a internal spacer (ITS) that was documented by NCBI, PQ721627. Following the application of ultraviolet light at a wavelength of 253nm to the conidial suspension of P. griseoroseum at different distances of 15 cm from the source (UV1=2, UV2=4, UV3=6) min., the extracts were evaluated by GC-MS with regard to their secondary metabolites. 1-O-p-Nitrobenzoyl-2,3,4,6-tetra-O-benzyl-.beta.-d-galactose, -Hexadecenoic acid, methyl ester, (Z)-, Triacontane, 11,20-didecyl-,d-Arabino-hexonic acid, 2-deoxy-3,4,5-tris-O-(trimethylsilyl)-, trimethylsilyl ester, bis, and Androsta-3,5-diene-3,17-diol, 3-(heptafluorobutanoate) 17-(pentafluoropropanoate) are among the new chemical compounds that were identified as a result of the mutations, there are also some compounds that have disappeared due to mutation such as 2- (N-Methyl-N-nitroamino)-4-[2,2,3,3,3-pentafluoro-1,1-bis(trifluoromethyl)propyl]-6 and Octatriacontane, 1,38-dibromo- .
