*Email: [email protected] 123 Natural Radioactivity and Hazard Indices of Soil Sample in Al-Dura thermal Power Plant in the Southern of Baghdad-Iraq
...Show More Authors

The presence of natural radioactivity in soil and other materials results in internal and external exposure in twelve samples at Al_Dura Heating generator at south of Baghdad using NaI(Ti) detector .Therefore, it is desirable to determine the concentration of naturally occurring radionuclide's238 U 232Th and 40 K,.. natural radioactivity and associated radiation hazard in some soil samples. The natural radioactivity due to the presence of 238 U 232Th and40 K in soil samples was measured by gamma spectrometry using NaI(Tl) scintillation well-shaped detector. In this context, soil samples were collected from thirty different locations of southern Al-Dura thermal Power Plant.Radium equivalent activities were calculatedfor the analyzed samples to assess radiation hazards arising due to the presence of these radionuclide's in the samples most of the calculated radium equivalent activities are lower than the limit set in the OECD report at 370 Bq/K.The measured representative level index values for the investigated samples varied in 1.035- 0.375 & 0.630- 0.1380 Bq/kg the range external and internal hazard index (Hex,Hin) , The radiation hazard indices of soilwas also lower than the maximum suggested global value the values of the Hex and Hin indices must be less than unity (˂1) for the radiation hazard to be negligible the specific dose rates indoor (D) and the annual effective dose (DE) due to gamma radiation from building materials was calculated.The value of the representative gamma index (Iγr) for the all soil samples were greater than the unity (>1).

Comparative Analysis for the Seasonal Variations of the IF2 and T Ionospheric Indices during Solar Cycles 23 and 24
...Show More Authors

In this work, a comparative analysis for the behavior and pattern of the variations of the IF2 and T Ionospheric indices was conducted for the minimum and maximum years of solar cycles 23 and 24. Also, the correlative relationship between the two ionospheric indices was examined for the seasonal periods spanning from August 1996 to November 2008 for solar cycle 23 and from December 2008 to November 2019 for solar cycle 24. Statistical calculations were performed to compare predicted values with observed values for the selected indices during the tested timeframes. The study's findings revealed that the behavior of the examined indices exhibited almost similar variations throughout the studied timeframe. The seasonal variations were

BRCA1 Gene Expression is Down Regulated in Both Familial and Sporadic Breast Cancer Cases in Baghdad- Iraq
...Show More Authors

Breast cancer is the commonest cancer and the leading cause of malignancies-related mortality in women worldwide. Understanding the underlying biology of the disease could improve patients’ stratification and may offer novel therapeutic targets and strategies. This study was set to investigate the association between BRCA1 gene expression and some of the clinical features of breast cancer patients in Baghdad-Iraq. Eighty peripheral blood samples were collected from sixty patients diagnosed with breast cancer and twenty healthy age-matched controls for BRCA1 qPCR gene expression analysis.

     The results showed a significant reduction in BRCA1 gene expression in all of the bre

EXPERIMENTAL INVESTIGATION OF LAMINAR NATURAL CONVECTION HEAT TRANSFER IN A RECTANGULAR ENCLOSURE WITH AND WITHOUT INSIDE PARTITIONS
...Show More Authors

Experimental study has been conducted for laminar natural convection heat transfer of air flow through a rectangular enclosure fitted with vertical partition. The partition was oriented parallel to the two vertical isothermal walls with different temperatures, while all the other surfaces of the enclosure were insulated. In this study a test rig has been designed and constructed to allow studying the effect of Rayleigh number, aperture height ratio, partition thickness, the position of aperture according to the side walls and according to the height, the position of the partition according to the hot wall, and partition inclination. The experiments were carried out with air as the working fluid for Rayleigh number range (5*107 – 1.3*10

BIOSTRATIGRAPHY OF THE ANAH AND EUPHRATES FORMATIONS AT WADI BANAT AL-HASSAN (W. IRAQ)
...Show More Authors

The purpose of this study is to elucidate the microfacies and the biozones present in the studied rocks as well as to determine their environments or deposition. The study depends mainly on the benthonic foraminiferal assemblages identified from (27) rock thin sections made available from an outcrop at Wadi Banat Al-Hassan area in the Upper Euphrates Valley. X-Ray diffraction was also used to determine the type of carbonate minerals present in the studied rocks.

This paper aims to evaluate the hydraulic characteristics of the aquifer between Al-khassa dam and Kirkuk structure, Kirkuk/ NE Iraq. Pumping tests applied for selected wells in the area to evaluate the hydraulic characteristics of the aquifer, special distribution of the water table and groundwater movement direction of the groundwater, the hydraulic properties results of five single pumping test in the study area showed that the transmissivity (T) is ranged between (2.01 to 7. 5 m2/day ), storage coefficient (Sc) ranged (6.4 * 10-3 to 7.3 * 10-2) and the hydraulic conductivity (K) is ranged between (0.025 to 0.35 m/day) that calculated by Winlog software, groundwater discharge of the area is equal to

Topology Molecular Indices Relationship of Electronic Properties of N-Alkanes and Branched Alkanes
...Show More Authors

    Eight electronic properties; HUMO, LUMO, HOMO-LUMO energy gap, dipole moment point-charge, dipole moment hybrid, molecular weight, heat of formation and zero-point energy of 60 normal and branched alkanes were examined using topology molecular indices. All the electronic properties were calculated using semi-empirical self-consistent molecular orbital theory. The relationship of electronic calculation properties with seven models of topology indices based on degree and/or distance were obtained in terms of their correlation, regression and principal component analysis. Most of the properties were well-modelled (r2 > 0.82) by topology molecular indices except the dipole moment point-charge and hybrid. The PCA resulted

Experimental Study of Natural Convection in a Closed Cavity (Static Type Domestic Fridge)
...Show More Authors

This work provides an analysis of the thermal flow and behavior of the (load-free) refrigerator compartment. The main goal was to compare the thermal behavior inside the refrigerator cavity to the freezer door (home refrigerator) effect and install a fan on the freezer door while neglecting the heat transmitted by thermal radiation. Moreover, the velocity distribution, temperature, and velocity path lines are theoretically studied. This was observed without affecting the shelves inside the cabinet and the egg and butter places on the refrigerator door as they were removed and the aluminum door replaced with a glass door. This study aims to expand our knowledge about the temperature and flow fields of this refrigerator mo
