Experimental study of nonlinear characterization of hybrid SWCNTs/Ag-NPs fluids, using nonlinear diffraction technique
...Show More Authors

Based on nonlinear self- diffraction technique, the nonlinear optical properties of thin slice of matter can be obtained. Here, nonlinear characterization of nano-fluids consist of hybrid Single Wall Carbon Nanotubes and Silver Nanoparticles (SWCNTs/Ag-NPs) dispersed in acetone at volume fraction of 6x10-6, 9x10-6, 18x10-6 have been investigated experimentally. Therefore, CW DPSS laser at 473 nm focused into a quartz cuvette contains the previous nano-fluid was utilized. The number of diffraction ring patterns (N) has been counted using Charge - Coupled- Device (CCD) camera and Pc with a certain software, in order to find the maximum change of refractive index ( of fluids. Our result show that the fraction volume of 18x10-6 is more nonlinearity than others.

Histomorphometrical Study of Placental from Male and Female Neonates of Diabetic Women
...Show More Authors

      Objective: To investigate occur the histomatrical alternations in placental terminal villi and their vessels of Iraqi diabetes (gestational diabetes and overt diabetes) and normal pregnancies were born male and female neonates. Methods: The hitometrical study of male and female terminal villi of 68 placentae in maternal diabetes mellitus (34 gestational diabetes, 34 overt diabetes (17 DM type 1 and 17 DM type 2) and 34 normal placentae. These placentae obtained from Department of Obstetrics and Gynaecology in three hospitals in Baghdad city. Results: The study showed that there is a statistically significant with higher diameter in central and peripheral sections of the terminal villi and their vessels in m

Study of Some Structural Properties of Porous Silicon Preparing by Photochemical Etching
...Show More Authors

Porous Silicon (PSi) has been produced in this work by using Photochemical (PC) etching process by using a hydrofluoric acid (HF) solution. The irradiation has been achieved using quartz- tungsten halogen lamp. The influence of various irradiation times on the properties of PSi اmaterial such as layer thickness, etching rate and porosity was investigated in this work too.
The XRD has been studied to determine the crystal structure and the crystalline size of PSi material

Study of Antibacterial, Antioxidant Activity and Biochemical Parameters of Different Honey Samples
...Show More Authors

     The present study was undertaken to determine and compare the antibacterial and biochemical characteristics of honey samples from Kurdistan region in Iraq and Arabian Gulf region. Sixteen honey samples of mixed floral origins from both regions were analysed and compared. Antibacterial activity of the honey samples was investigated against five clinical pathogenic bacteria: Acinetobacter baumannii, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi and Staphylococcus aureus by agar dilution method. Both sample sets showed differential biochemical characteristics and potential functional properties such as antioxidant and antimicrobial properties. All measured parameters were within accepted ranges. Howev

Simulation Study of Sputtering Yield of Zn Target Bombarded By Xenon Ions
...Show More Authors

    Using a reduction of TRIM simulation data, the sputtering yield behaviour of Zinc target bombard by heavy Xenon ions plasma is studied. The sputtering yield as a function of Zinc layer width, Xenon ion number, energy of ions, and the angle of ion incidence are calculated and illustrated graphically. The corresponding energy loss due to ionization, vacancies and phonons, are graphically shown and discussed. Further, we fit the calculations and expressions for fitted curves are presented with its coefficients.

Study of Thermal Stability of Tetraphenanthroporphyrazine and SomeMetal Complexes By Thermogravimetric Analysis .
...Show More Authors

The thermal stability of previously prepared tetraphenanthroporphyrazine (TPPH2) and its complexes with VO(IV) , Co(II) , Cu(II) , Zn(II) , Mg(II) , Ca (II) ions were studied by thermogravimetric analysis (TG & DTG) at temperature range (20-1000oC). The results indicated that these compounds have a high thermal stability comparable to those of phthalocyanine compounds (PC) and higher than those of hemiporphyrazine compounds (HP) . In general metal complexes were more stable than parent ligand . Data of magnetic susceptibility and electrical conductivity were also obtained as further support for the studied compoundes .
