The QCD theory is implemented by deriving the photon emission rate equation of the state of ideal QGP at a chemical potential. The photon rate of the quark-gluon interaction has to be calculated for the anti up-gluon interaction in the g → γ system at the temperature of system with critical temperature ( 132.38, , and 198.57) MeV and photon energy ( GeV. We investigated a significant effect of critical temperature, strength coupling, and photon energy on the photon rate contribution. Here, the increased photon emission rate and decreased strength coupling of the quark-gluon reaction due to the decrease in temperature of the system from 360 MeV to 180 MeV are predicted. Photon energy in the range (1 to 10) GeV and the rate spectrum of four varieties of critical temperatures are presented.\u0000 \u0000The interesting point in our results is the minimum value of photon rate, especially in the photon energy E=10 GeV of ﬂavor which reflects the poor coupling between quark and gluon in the the g → γ system which was already expected. The features of QCD results are achieved in the case of ﬂavors for the photon energy E=1 to 10 GeV, the strength coupling and the photo meason rate are calculated theoretically. We can notice that the asymptotic behavior, which was characterized by a hadronic phase limit, will be satisfied.","PeriodicalId":13022,"journal":{"name":"Ibn AL- Haitham Journal For Pure and Applied Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89223857","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}

Solar thermal collectors are well thought out to be the most effective process of converting and harvesting solar radiation. In this investigation, Cu/TiON/CrO2 multilayered solar selective absorber coatings have been coated onto Al substrates using the dip-coating process followed by an annealing process at (400, 450, 500, 550, and 600 °C. The XRD analysis showed excellent crystalline quality for the prepared thin films along with enhanced surface features as proved by FESEM images, and the grains are in the range of (27–81) nm. The optical investigations revealed that the film annealed at 600 °C exhibits improved solar absorptance, thermal emittance, and solar selectivity of ~ (90.7 %), (5.8 %) and 15.6, respectively. Also, the highest values of hardness ~ (26.8 GPa) and Young’s modulus ~ (250 GPa) were assigned for the film annealed at the highest temperature. Calculated optical band gaps of fabricated thin multilayered Cu/TiON/CrO2 films were found to be in the range of (1.8 – 2.10) eV.","PeriodicalId":13022,"journal":{"name":"Ibn AL- Haitham Journal For Pure and Applied Sciences","volume":"168 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90206746","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 present investigation aimed to evaluate the impacts of drought stress with three periods for irrigation: every 3 days(control), every 6 days, and every 12 days and foliar spray with different concentrations of ascorbic acid (0, 75, 150, 225) mg.L-1 on the wheat plant. Pots experiment was conducted as a completely randomized design with three replications in the green house, Department of Biology, College of Education for Pure Science (Ibn Al- Haitham), University of Baghdad, during the growing season, 2018 – 2019. The results indicated that drought stress decreased plant growth and hastened the senescence of flag leaves, which is significantly associated with a decrease in the quality and quantity of grain yield. Foliar spray with ascorbic acid enhanced plant drought tolerance in terms of plant height, shoot dry weight, flag leaf traits (flag leaf area, flag leaf chlorophyll and the concentration of macronutrients such as nitrogen, phosphorous, potassium) and some yield components (spike length, grain weight. pot-1 and protein percentage of grains). The results indicated the efficiency of ascorbic acid foliar spray on vegetative growth, flag leaf traits and some yield components of wheat plants affected by drought stress and the superiority to 150 mg.L-1 ascorbic acid in which plants can resist the unfavorable drought stress periods(12 days).","PeriodicalId":13022,"journal":{"name":"Ibn AL- Haitham Journal For Pure and Applied Sciences","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87355971","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}
