The researcher stated that he prepared some compounds from (NiO)1-x (ZnO)x with different proportions of zinc oxide by mixing nickel oxide with high-purity zinc oxide, then put the mixture in an oven at 1273 ° C for five hours. The resulting powders were ground and pressed into tablets. Thin films of (NiO) 1-x (ZnO) x were prepared by using the 0.1M pulsed laser deposition method on different surfaces such as glass and silicon chips.

He added that the composition of the compounds and prepared films were examined using X-ray diffraction. The X-ray spectrum showed that all the prepared compounds and membranes were of a polycrystalline structure and that the peaks were identical with the cubic phase and the hexagonal phase of nickel oxide and zinc oxide at the content x = 0.0 and x = 1.0 respectively. On the other hand, the peaks were identical for both phases at other proportions.

The student explained that the goal of the work was to prepare thin films of (NiO) 1-x (ZnO) x on glass and silicon using PLD, measure the structural, electrical and optical properties of the (NiO) 1-x (ZnO) x thin films prepared on glass and manufacture a gas sensor from the thin films prepared on silicon for sensing NO₂ and NH₃.

The researcher stated that the current study included collecting venous blood samples from (85) type 2 diabetes patients, in addition to (20) samples from healthy volunteers. Then, various biochemical indicators were estimated using Cobas spectroscopy. A special questionnaire prepared by the UK Health Foundation (UKDDQ) was also used to conduct human and demographic measurements related to the type of food and determine the amount of fruits and vegetables consumed by each volunteer in the study. The concentrations of vitamins (A, E, and C) in plasma were estimated using high performance chromatography (HPLC) device. The IBM SPSS statistical program and the GraphPad Prism 8 program were used to conduct all statistical analyses. The Unpaired t-test was further used to analyze most of the data obtained.

The researcher concluded that a balanced diet should include balanced quantities of fruits and vegetables as a source of vitamins, minerals and other supplements. This plays a role in developing antioxidant efficacy in healthy people as well as in type 2 diabetes patients, in addition to reducing the risk of possible complications of the disease.

The discussion was held at the Great Hall in the College of Science on Tuesday 15/9/2020.

The researcher stated that he conducted a comprehensive descriptive study of the characteristics of the cerium isotopes (Ce ^142-152) within the first microscopic interacting boson model (IBM-1). The energy of mass nuclear states was studied using the PHINT program. Some energy levels were also predicted and the Uberm equivalence was confirmed for some cases. Additionally, the energy levels in the domain β were also predicted by estimating the energy of the second state with a twist and symmetry for the isotopes Ce ^142-152.

He added that he calculated the reduced transitions probability of the electric quadrupole B(E2) and the magnetic dipole B(M1). The electromagnetic mixing ratio and quadrupole momentum of the isotopes under study were also calculated using the FBEM code.

The researcher compared the calculated results with the available experimental data and found that in general the comparisons are in good agreement with the experimental data. The isotope Ce ¹⁴² has the properties of vibrational determination and the isotope Ce ¹⁵² is very close to the rotational limit of SU (3). Whereas the isotopes Ce ^144-150 have the properties of the transition region U(5) -SU(3), so they are considered first-order phase transition nuclei.

It is noteworthy that the study was conducted under the supervision of Prof. Dr. Amir Abdul-Amir Muhammed Ali of the College of Science, Karbala University. The discussion committee was composed of Prof. Dr. Ali Khalaf Hasan of the Kufa University, Prof. Uday Dawood Salman of the College of Science, Karbala University, and Prof. Dr. Fadhil Ismail Sharrad of Al-Ain University.

The researcher stated that she prepared the azo aldehyde derivative through the reaction of a base solution of hydroxyl benzaldehyde compound with the diazonium salt solution of the amino-benzothiazole compound. The resulting aldehyde compound was treated with some available anilines.

She explained that she used the microwave agitation technique in absolute ethyl alcohol to obtain seven amine derivatives of benzothiazole respectively. As the cyclic addition of the resulting amines with succinic anhydride by using microwave technology in a small amount of benzene gave seven new oxazpan dione derivatives carrying the benzothiazole unit, respectively. On the other hand, the treatment of intermediate amines with phthalate anhydride by using microwave technology in a small amount of benzene produced seven new benzoxazepine diene derivatives carrying one benzothiazole unit, respectively.She added that she diagnosed the final compounds’ structures by means of quantitative elemental analysis (CHNS) and spectroscopic methods including infrared spectroscopy and proton magnetic resonance. And to test the bioactivity of the required compounds against two types of bacteria, Staphylococcus aurous, positive for Gram and Escherichia coli, negative for Gram stain. As the test results indicated that all the compounds of Oxazepine and Oxazepine showed a greater effect than gentamycin towards the positive bacteria for the Gram stain. Moreover, most of the compounds showed a greater effect than gentamycin against the negative bacteria for the Gram stain.

It is to be mentioned that the study was conducted under the supervision of Prof. Dr. Zaid Hasan Aboud of the College of Science, University of Karbala.
