The influence of the wind speed and the angle of attack on the aerodynamic noise was investigated in this study. Four different samples of airfoils were used. Three speeds (5, 10, 15 m/s) were employed. The results revealed that the aerodynamic noise was associated directly with the flow speed. The data showed that when the velocity increases by (5 m/s), the noise gets louder by an average amount of (10 dB). As the increase of flow velocity increased the velocity shear, this eventually increased the aerodynamic noise. As for the angle of attack, it had an effect on the aerodynamic noise as well. The results showed an increase in the overall sound pressure level between (1-4 dBA) when the angle of attack increased from (5 degrees) to (10 degrees), while there was an increase (1-6 dBA) when the angle of attack increased from (10 degrees) to (15 degrees). This study was conducted under subsonic flow condition and Reynolds number (3.3×104).","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"5 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139158716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, minor changes were made to the BRB-CG method used for addressing the optimization algorithms discussed. Then, a new 3-term BRB-CG (MTTBRB) was presented. This new method solved large-scale unconstrained optimization problems. Despite the fact that the BRB algorithm achieved global convergence by employing a modified strong Wolfe line search, in this new MTTBRB-CG method the researchers employed the classical strong Wolfe-Powell condition (SWPC). This study also attempted to quantify how much better 3-term efficiency is than 2-term efficiency. As a result, in the numerical analysis, the new modification was compared to an effective 2-term CG- method. The numerical analysis demonstrated the effectiveness of the proposed method in solving optimization problems.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"19 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139157798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study comprised a total of 54 subjects including patients with beta thalassemia (n=27) and healthy volunteers (n=27) matched by age and gender. Hematology (Hb and % PCV), 5'-nucleotidase, Ferritin, GSH and MDA were measured using different methods and devices.

According to these studies, the area includes two main igneous rock units: The Penjween Ophiolite Complex comprised of gabbro, peridotite, and granitoid intrusions at the south. The second unit is Kata Rash Volcanic rocks (Kata Rash conglomerate of the present study) which are located in the north and northeast and comprised of mafic, intermediate and felsic volcanic rocks. The present study disagrees with the previous documentation of these rocks and changed the claimed Kata Rash Volcanic Rocks and Penjween Ophiolite to metamorphosed conglomerates and coarse sandstones of the proximal facies that belong to metamorphosed sediments of Walash Formation (or Group) that was deposited in a large Paleocene Foreland Basin. The Walash Group and Kolosh Formation (as unmetamorphosed, coarse and fine sandstones or greywackes) were deposited as deep basin distal facies in the basin while Kata Rash Conglomerate belongs to coastal facies. All the above five units are deposited by turbidity currents during Paleocene-Eocene and they correlated, in the present study, stratigraphically along the basin paleodip from the present location of the Shalair valley to the south of Sulaymaniyah City. The Naopurdan Formation is recognized for the first time in the Penjween area and its facies and foraminifera are documented and correlated with Sinjar Formation. The above siliciclastic sediments were derived from volcanic source areas inside Iran and depending on the field, lab, and evaluations of the previous studies, the present study drew sedimentary stratigraphic columns and cross-sections for the Penjween and Sulaimanyiah areas and correlated their units along 100 km across the latter two areas. The correlation linked the Kolosh Formation with stratigraphic units of the Penjween area for the first-time supposing deposition during Paleocene-Eocene and sharing the same foreland basin which is aided by the first record of the occurrence of the Kolosh Formation in Chwarta by nannofossils and petrography.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"11 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139158405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this study aimed to produce zinc oxide nanoparticles using a simple and eco-friendly biosynthesis process, utilizing the Eucalyptus (Eucalyptus camaldulensis Dehn.) as a reducing agent. It also aimed to estimate their insecticidal efficacies toward the mealworm's stages (Tenebrio molitor L.,1758(. The produced ZnO nanoparticles were characterized by X-ray diffraction, UV–visible, and transmission electron microscopy (TEM). The laboratory experiment was carried out with one way of exposure, using the feeding method through immersing the leaf in ZnO NPs solution with different concentrations. The mortality effects on insect's stages were recorded in various periods of time. The statistical analysis results indicated the presence of noteworthy variations in the average mortality rate according to insect's stage, showing a different effect on the average of larval mortality rate. In this regard, the highest average of larval mortality rate was recorded at 5000ppm (61.25%); while the general average percentage of adult emergence was (42.53%). After three weeks, the highest general mean of adult mortality was obtained at 5000ppm (87.48%). Similarly, the LC50 value of the ZnO NPs derived from the used plant extract against the larval stage was (3630.78 ppm). This result revealed that Zinc Oxide Nanoparticles from plant extract sources have both larvicidal and adulticidal properties and they could serve as an eco-friendly alternative to synthetic insecticides for controlling insect's stages. Hence, the biogenic Zinc Oxide Nanoparticles can be used as a potential bio-insecticidal agent for the future.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"14 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139157463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The renin-angiotensin system (RAS) is well known as regulator of electrolytes and blood pressure. Renin is previously considered a major enzyme in this system. The study included 90 blood samples for married women of childbearing age between (18-45) years. These samples included 70 samples for women with polycystic ovary syndrome, which were divided into two groups (35 samples in each one), the first was withdrawn in the follicular phase, named PA, and the second in the luteal phase of the menstrual cycle named PB. As for the remaining 20 samples, they represented the control group of healthy women, which were also divided into two groups (CA and CB) as happened with the patient group. In this study, the levels of serum Renin, ACE, LH, FSH and Kallikren5 were evaluated in PCOS patients and compared with the control group in both phases. The results were analyzed by T-Test and ROC. There were no significant differences between patients and the control group in terms of ACE activity or FSH (P>0.05).
