The performance of a diesel engine was tested with diesel oil contaminated with glycol at the engineering workshop/Department of Agricultural Machines and Equipment / College of the Agricultural Engineering Sciences at the University of Baghdad. To investigate the impact of different concentrations of glycol on the performance of a diesel engine, an experimental water-cooled four-stroke motor was utilized, with oil containing 0, 100, and 200 parts per million (ppm). Specific fuel consumption, thermal efficiency, friction power, and exhaust gas temperature were examined as performance indicators. To compare the significance of the treatments, the study employed a full randomization design (CRD), with three replicates for each treatment at th

     In this work, the switching nonlinear dynamics of a Fabry-Perot etalon are studied. The method used to complete the solution of the differential equations for the nonlinear medium. The Debye relaxation equations solved numerically to predict the behavior of the cavity for modulated input power. The response of the cavity filled with materials of different response time is depicted. For a material with a response time equal to = 50 ns, the cavity switches after about (100 ns). Notice that there is always a finite time delay before the cavity switches. The switch up time is much longer than the cavity build-up time of the corresponding linear cavity which was found to be of the order of a few round-trip ti

A total number of 68 water samples was revealed 20 isolates being Staphylococcus aureus. Irrigation water isolates represented 25% of isolates while wastewater 75%. all isolates were identified by morphological, microscopial, biochemical tests and VITEK®2 Compact. Bacterial isolates were subjected to 16 antibiotics, all irrigation water and wastewater isolates were resistant to penicillin while they were fully sensitive to Ciprofloxcin. Irrigation water isolates showed relatively greater multi-drug resistance than wastewater, wherein irrigation water isolates showed 100% multi-drug resistance while wastewater isolates showed 73.3% multi-drug resistance, indicating the ability of S. aureus MDR to move from one site to another, which means t

Trichomonas vaginalis is a unicellular flagellated protozoan that resides in female and male genital tract and considered the most prevalent sexually transmitted infectious parasite. The infection rate is relatively equivalent between male and female but trichomoniasis is usually asymptomatic in men. Primary triggering of host inflammatory response to this parasite is not fully understood and most studies address the local reaction of the parasite in female genital tract. In this study, two pro-inflammatory cytokines, IL-8 and IL-12, were investigated in the serum of infected women with Trichomonas vaginalis during acute and chronic stages of the disease. The results demonstrated that the level of IL-8 was significantly

The present study aims to assess the water quality and the hydrochemical characteristics and seasonal variation of surface water on the aspect of trace elements in Al-Tarmiyah District, Baghdad, Iraq. Ten water samples were collected, four from surface water and six from groundwater on October 2017, and on April 2018. All samples were analyzed for physiochemical parameters such as water temperature, pH, EC, TDS,TH,TSS, major ions (Ca²⁺, Mg²⁺, Na⁺, K⁺, SO₄^2-, Cl^-, and HCO₃^-), and nutrients (NO₃^-, and PO₄^3-). In addition, samples were analyzed for trace elements that include Fe, Al, Pb, Zn, Mn, Cr,

Back ground:-Rheumatoid arthritis (RA) is a systemic disease characterized by progressive, erosive  and chronic poly arthritis, where cellular proliferation of the synoviocytes and neo-angiogenesis leads to formation of pannus which destroys the articular cartilage and the bone .

Objective :-to evaluate theOxidative Stress index( OSI )by measuring malondialdehide( MDA) and Total Antioxidant Capacity( TAC) in serum of RA patients in addition to uric acid and albumin and to investigate the alteration in these parameters compared to healthy individuals.

Patients and Methods :- twenty five patients with rheumatoid arithritis  and twenty five apparen

The research aims to identify the extent to which Iraqi private banks practice profit management motivated by reducing the taxable base by increasing the provision for loan losses by relying on the LLP it model, which consists of a main independent variable (net profit before tax) and independent sub-variables (bank size, total debts to total equity, loans granted to total obligations) under the name of the variables governing the banking business. (Colmgrove-Smirnov) was used to test the normal distribution of data for all banks during the period 2017-2020, and then find the correlation between the main independent variable sub and the dependent variable by means of the correlation coefficient person, and then using the multiple

This study is designed to evaluate the immune status of patients and schoolchildren with respect to Streptococcus pyogenes. A prospective study was conducted to investigate antibody against GAS in children patients and asymptomatic healthy carriers in serum samples with tonsillitis and compare antibody response (ASO) between patients and healthy carriers with tonsillitis.
Tonsillar swabs were obtained to detect the presence of GAS and blood samples were collected to determine elevated ASO titer in serum.
A total of 376 sample patients and asymptomatic healthy carriers were included in this study, 142 (37.7%) samples are GABHS positive, included 80 (56.3%) patients and 62 (43.6%) asymptomatic healthy carriers. The finding of a signi

Background: Normospermia might be a major problem to the doctor and the infertile couple because the male seminal sample has an accepted seminal parameters during the routine seminal examination and the female partner will be claimed for the infertility and she will suffered from coasty, painful, time consuming, non indicated investigations and treatments. Our purpose was to measure sperm creatine phosphokinase (CK) activity, which reflects cytoplasmic retention in immature spermatozoa and malondialdehyde in the seminal plasma which is a marker of oxidative stress in normospermic infertile males' seminal samples.
Patient and methods: Nine infertile men with aberrantly normal standard seminal analysis&nbsp

A summary of zooplankton research done in Peruvian marine waters is presented. We first provide a brief overview of the evolution of zooplankton studies off Peru before reviewing zooplankton biodiversity, regional distribution, seasonal and interannual fluctuation, trophodynamics, secondary production, and modeling are some of these topics. We evaluate research on various meroplankton, macroplankton, mesoplankton, and microplankton groups and provide a list of species from both published and unpublished sources. Three regional zooplankton groups have been identified: A shelf group on the continental shelf dominated by Acartia tonsa and Centropages brachiatus; A slope group on the continental shelf with siphonophores, bivalves, foramin
