    Abstract In the present study, DSSCs were fabricated using pure ZnO NWs and ZnO NWs/Graphene nanocomposite as photoelectrodes. Graphene was incorporated into pure ZnO NWs through a cost-effective Hydrothermal Process to act as an electrical charge carrier. J-V curve of prepared nanocomposite was recorded with a light intensity of 100 mW.cm-2. The created nanocomposites were thoroughly investigated by using different electrical and structural characterization techniques such as SEM, XRD, and J-V characteristics. According to SEM examination, the ZnO NWs/graphene composite-based electrode has more porosity than the electrode made using pure ZnO NWs, which will increase the surface area and the amount of dye that can be absorbed. From the graphene advantages the reduced internal resistance and electron recombination loss, these properties allow electrons to transfer to the collection electrode efficiently. Based on these benefits, the ZnO NWs/Graphene nanocomposite photoanode with thickness of 965.11 nm that was used in the DSSC2 was demonstrated a Jsc of 19.50 mA.cm-2 and conversion efficiency of 9.829053%, which opposite to the result of the DSSC1 without graphene. These results can be encouraged for future improved optoelectronic devices.

    Abstract Introduction: Mastalgia was the most common symptom in patients attending a breast clinic. The two most common types of mastalgia were (cyclical and non-cyclical). The common cause of cyclical was Physiological changes due to premenstrual tension syndrome fibrocystic changes or fibroadenosis and (Aberrations in the Normal Development and Involution of the breast ). Non-cyclical diseases are mainly benign rather than malignant. Solid masses (fibroadenomas), cysts, infections, abscesses, trauma, and nipple discharge (hormones) are rare diseases associated with breast cancer. The aim of this study is to study the incidence of mastalgia, types (cyclical and non-cyclical) and pathological types of mastalgia (benign and malignant pathologies).
    Material and methods: A cross-sectional descriptive study of mastalgia was carried out at the Breast Center Department of Maternity Teaching Hospital located in Erbil, from January 2014 to September 2015. A total of 150 breast pain cases (available clinical data) were studied in detail.
    Results: There are two types of mastalgia based on triple assessments, these are as follows, cyclical 90 cases (60%) and non-cyclical 60 cases (40%). Fibrocystic breast changes or fibroadenosis 35 cases (23.3%) and thirdly nipple discharges as part of fibrocystic (fibroadenosis) five cases (3.3%). Non-cyclical mastalgia was subdivided into benign breast pathologies, fibroadenoma 30 cases (20%), breast cyst 10 cases (6.7%), nipple discharge (hormonal) five cases (3.3%), mastitis three cases (2%) abscess two cases (1.3%), fat necrosis one case (0.7%), and malignant breast pathologies, cancer three cases (2%). Clinicopathological correlations in the current study were highly significant (
    Conclusion: Not all discomfort or pain can be diagnosed as mastalgia; occasionally, chest wall, referral pain, and systemic causes can mimic mastalgia. These results highlight the importance of differentiating between cyclical and non-cyclical mastalgia using clinical assessment, sonography, mammography, and blood investigations. Most mastalgia cases are benign, with cyclical mastalgia primarily related to hormonal changes during the menstrual cycle.

    Abstract The purpose of the study is to assess the Environmental Flow Requirement (EFR) of Gorai River in Bangladesh and to evaluate the change in flow characteristics in recent time compared to past. Daily discharge data of Gorai railway bridge station were collected from Bangladesh Water Development Board and analyzed for two periods. Mean Annual Flow (MAF) in G2 period (2000-20166) is found about 13% lower than G1 period (1984-1999). The Mean Monthly Flow (MMF) in low flow season is increased by 99%, and that of high flow is decreased by 20% in G2 period compared to G1. In this study, EFR was determined considering various methods including Tennant, Tessmann, Variable Monthly Flow, Modified Constant Yield, FDCA Q

    Abstract Background: Middle East respiratory syndrome (MERS) is a zoonotic viral disease transmitted from dromedaries to humans. To date, more than 1500 cases of MERS have been reported and 80% of all cases have occurred in the Kingdom of Saudi Arabia (KSA). This cross-sectional study was carried out to figure out the rate of infection among humans and dromedary camels and to explore the risk factors.
    Methods: This study was conducted in Diyala Province, Iraq for the period from August 2017 to October 2018. Human subjects included 90 participants; 34 (37.8%) were females and 56 (62.2%) were males. Additionally, 90 dromedary camels were also included, 50 (55.6%) males and 40 (44.4%) females. Serum samples from subjects were collected and tested for the presence of anti-MERS-coronavirus (CoV) immunoglobulin g (IgG).
    Results: The results revealed that 46 (51.1%) of human subjects were positive for anti-MERS-CoV IgG, (95% confidence interval (CI) for the prevalence rate 40.9-61.3) with a mean titer of anti-MERS-CoV IgG antibodies (Ab) of 81.2 U/mL. The anti-MERS-CoV IgG positivity rate was insignificantly higher, but the mean of anti-MERS-CoV IgG titer was significantly higher among females (p = 0.12 and p < 0.004, respectively). Furthermore, the anti-MERS-CoV IgG positivity rate and Ab titer were significantly higher among those people who visited KSA for Hajj or Umrah (p < 0.001 and p < 0.001, respectively). In camels, 81 (90.0%) were positive for anti-MERS-CoV IgG, (95% CI for the prevalence rate 82.5-94.9), with a mean titer of 99.8 U/mL.
    Discussion: The MERS-CoV infection rate was high among both Iraqi humans and dromedary camels. Further confirmatory studies are needed, and setting up of national precaution program is essential.

    Abstract The detection and identification of induction motor faults using machine learning and signal processing is a valuable approach to avoiding plant disturbances and shutdowns in the context of Industry 4.0. In this work, we present a study on the detection and identification of induction motor faults using machine learning and signal processing with MATLAB Simulink. We developed a model of a three-phase induction motor in MATLAB Simulink to generate healthy and faulty motor data. The data collected included stator currents, rotor currents, input power, slip, rotor speed, and efficiency. We generated four faults in the induction motor: open circuit fault, short circuit fault, overload, and broken rotor bars. We collected a total of 150,000 data points with a 60-40% ratio of healthy to faulty motor data. We applied Fast Fourier Transform (FFT) to detect and identify healthy and unhealthy conditions and added a distinctive feature in our data. The generated dataset was trained different machine learning models. On comparing the accuracy of the models on the test set, we concluded that the Decision Tree algorithm performed the best with an accuracy of about 92%. Our study contributes to the literature by providing a valuable approach to fault detection and classification with machine learning models for industrial applications.

    Abstract Background: Contrast-induced nephropathy (CIN) is associated with increased mortality and morbidity in patients undergoing coronary angiography (CAG) and percutaneous coronary intervention. This study aimed to compare the incidence of CIN in two groups of patients with and without metabolic syndrome (Mets) with baseline normal renal function.
    Materials and methods: In this case - control study, 260 patient candidates for CAG, 130 patients with Mets and 130 patients without Mets participated, and their serum creatinine (Cr) level before and the 48 and 72 h after the angiography was measured. The incidence of CIN was compared in two groups. Two-way analysis of variance with repeated measures and univariate and multivariate logistic regression models.
    Results: The results showed a higher chance of being Mets with raising in triglyceride (adjusted odds ratio = 1.05, 95% confidence interval = (1.03-1.06),
    Conclusion: Mets, together with other risk factors, increased the overall risk of CIN development. Therefore, the incidence of CIN in patients Mets is significantly higher than that of patients without Mets, indicating a more important CIN risk factor.

    Abstract Soil and water salinity is an important limiting factor affecting yield and production levels in arid and semi-arid areas. Salt tolerance during germination is an important parameter that also affects the other plant development stages. In this respect, this study was designed to determine the responses of pumpkin seed varieties (Develi, Ürgüp, Hybrid) to different NaCl salinities. The study was carried out in 2022 in the laboratory of Biosystems Engineering Department of Erciyes University in randomized plots design with 3 replications. Experiments were conducted with 5 different water salinity. Germination percentage (GP), germination index (GI), mean germination time (MGT), seedling vigor index (SVI), ion leakage (Il), radicula length (RL) and plumule length (PL), root and shoot fresh and dry weights and some mineral composition (Na, K, Ca) were examined. Proline, antioxidant capacity, total phenolic and DPPH content were significantly affected by salinity. In scatter plot correlation analysis SVI a positive correlation was observed between GP (r
