Authors: Ali Yonis Saleh  , Adeba Y. Shareef Al-Numan  
Published: April 2023

Blood transfusions was considered as a source of a number of infections in some cases if the donor is infected, especially the virus and parasitic ones, in which the blood is the main route of transport if it is contaminated from the environment or during the transport. The current study included testing (250) blood samples for Thalassemia patients and (100) blood samples from healthy subjects as a control , The samples included with (134) males and (116) females with mean age of (13.87 ± 9.37) years for patients and (14.08 ± 6.45) years for control samples. And for the period from February 2017 to July 2017 And patients who were diagnosed by specialists in Ibn al-Atheer teaching Hospital for Children in Nineveh Governorate. The study showed a high rate of infection with CMV infection in male thalassemia patients (42%) while in females (36.1%), the highest rate of infection was in the age group 16 years and above and the increase in the number of blood transfusions increases the rate of infection (46.5%) in patients received blood twice or more per month and decreased to (37.6%) in patients who receiving blood once a month. The highest rate of Toxoplasma infection was found in females (18.3%) while in males (15.6%). The highest age group (6-10) years showed the highest percentage of infection (19.1%). Blood infected patients with T. gondii recieving blood twice per month formed (21.9%) while those receiving blood one time per month decreased to (15.9%) .

Qulqula Formation studied in Suren mountain - Sulaymaniyah- NE Iraq. 10 samples collected from the outcrop near Kani Seif Hamid area. Petrographic and mineralogical investigation carried out, thin sections, X- ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Analysis (EDX) samples were prepared and analysed in Wollongong University-Australia. Preliminary results show that the lower part of Qulqula Formation in the studied section undergo severe recrystallization and partly dolomitized. In addition, from chronostratigraphic viewpoint, Qulqula Formation in the studied area thought to represent Late Triassic age. This study report for the first time the occurrence of Calpionellids fossils, two species were identified; Tintinnopsella remanei Borza and Calpionellites major (Colom) which represent the Late Jurassic - Early Cetaceous age (i.e. Late Tithonian - Early Valanginian respectively). This coincided with the proposed age results from previous works.

Published: April 2023

In the present study, we calculated the imaginary part of the x-ray scattering factor of nickel based on the principles of quantum mechanics to find a wave function that describes the electronic state of atoms by approximate methods, observed the study suggested that in both low energy values , and at high energy values , the imaginary part is approximately zero, this means that the electrons are intensely connected to the atom, where in the spectrum the photon energies are approximately equal to the electron bonding energy we note the study pointed out that the imaginary part of the atomic scattering factor become prominent and the electron becomes highly absorbent, the relative accuracy varies within range (0.03-0.22)%, and there was also a good agreement between the behavior we obtained for the imaginary part of the atomic scattering factor and the behavior that was calculated using other models.

In this study, a liquid crystal display LCD cell was prepared. with the windows made from a thin film of SnO2 add to it Bi2O3 by weight (0,1,3,5,7)% .The effect of adding optical and electrical properties of the cell was studied. The thin film was prepared by vacuum evaporation technique. It was added to use powder mixing technique. The results showed a decrease in the value of the current passing through the cell and an increase in resistance value from 9.7MΩ to 12.5MΩ. The results also showed an increase in the cell's ability to control the light and darkness it with lower voltages by increasing the add rate. This leads to a decrease power used of a single cell. The value of the capacitance is not affected by the addition of Bi2O3 and was stable at ( 3nf ±1% ).

Desv., Lepidum aucheri Boiss., Sisymbrium irio L., Sisymbrium officinale (L.) Scop., and Sisymbrium septulatum DC. Leaves powder of these taxa were collected and analyzed by High-performance liquid chromatography (HPLC). The results identified 9 phenolic compounds, chlorogenic acid, cinnamic acid, ferulic acid, genstic acid, kaempferol, p-coumaric acid, protocatechuic acid, sinapic acid, and vanillic acid. The results showed that the genus Lepidium aucheri had the highest concentration of 4 phenolic compounds, cinnamic acid, genstic acid, p-coumaric acid, and sinapic acid with concentration of (37.2, 80.79, 62.91, and 37.10µg/ ml) respectively. On the other hand, the genus Cardaria draba showed the lowest concentration of 3 phenolic compounds, cinnamic acid, p- coumaric acid, and protocatechuic acid, and doesn't have 2 phenolic compounds, genstic acid and kaempferol. This variation in the phenolic concentrations might be due to the genotype and plant growth stage differences. The results of this study provide a source for bioactive compounds to future studies.

The anticline is located in NE Iraq, within the High Folded Zone of the Iraqi Western Zagros Fold – Thrust Belt where the southwestern limb of it represents the boundary between the Low and High folded zones. The age of the exposed rocks in the study area ranges from Cretaceous to Late Pliocene. Qamchuqa and Kometan formations expose in the two limbs as oldest rocks, while the youngest rocks in the northeastern limb are covered by Dokan Conglomerate. Consequently the fold geometry was determined by the measured field data of Qamchuqa and Kometan formations only. Khalakan anticline was described as asymmetrical and overturned fold, with northeastern vergency, where the mean attitude of the NE limb is 220 ᴏ/89 ᴏ and the mean attitude of the SW limb is 219 ᴏ/55° in terms of dip direction and dip amount. The attitude the fold axis in terms of trend and plunge is 130°/1°, the attitude of the axial plane is 220°/72° in terms of dip direction and dip amount, the interlimb angle is 34°, consequently the fold was classified as Close Fold.

Authors: Fareed M. Mohammed  , Sameh H. Salih  , Abdulkader A. Hassan  , Shalash A. Mohammed  
Published: April 2023

In this paper we used renormalized free atom model to study the electronic configuration of vanadium carbide compound. The theoretical values were obtained after finding the values of each element separately and using the superposition model to find the best electronic arrangement. These results were compared with experimental values measured by using high energy (661.65 keV)ɣ-radiations from a 137Cs source. We observed two things, first; if half the density of the electronic momentum of the compound is concentrated in vanadium we get the electronic order (2s1-2p1.5)C+(3d+5.5-4s1)V. second, if full the density of the electronic momentum of the compound is concentrated in vanadium we got the electron order (2s1-2p0)C+(3d+7-4s1)V .The best results out of these were when the full electron transfer from carbon to vanadium occurs.
