Ahdeb oil field is located in the central block of Mesopotamia plain in Iraq. It has three domes AD-1,   AD-2, and AD-4.The current study represents characterization of carbonate Mishrif reservoir (Cenomanian-Early Turonian) in three wells (AD-A,AD-B,AD-C) at southern dome of Ahdeb oil field. Petrophysical properties were calculated using available well logs data such as neutron, density, sonic, gamma ray, resistivity and self-potential logs. These logs are digitized and then environmental corrections and interpretations were carried out using Techlog software. Petrophysical parameters such as shale volume, porosity, water saturation, hydrocarbon saturation, bulk water volume, etc. were determined and interpreted and illustrate

In this work, polypyrrole (PPy) composites were chemically prepared by a chemical oxidation method. Also, Tungsten Trioxide (WO₃) nanoparticles were prepared and added in certain proportions to PPy. The structure properties were studied for the polypyrole and tungesten trioxide separately before mixing them together. The X-ray diffraction (XRD) analysis revealed a hexagonal WO₃ and a triclinic PPy. It was observed that the nano-composite prepared by the addition of WO₃  with 10 and 20% volume ratios to PPy shows a triclinic phase with the presence of hexagons. The molecular structures of PPy, WO₃, and PPy–WO₃ nano composites were depicted by Fourier-transform infrare

Various types of storing tanks are used to store municipal water at homes. This study was carried out to examine several water physical and chemical variables such as pH, EC, TSS and TDS after different storing periods. The obtained results showed no significant differences between the mean of pH values which ranged from 7.27 ± 0.04 in a water sample of galvanized tank after six days of storing to 8.10 ± 0.12 in water sample of aluminum tank after nine storing days. In case of electric conductivity, Highest mean values (1.85±0.09 μS/cm and 1.44 ± 0.21μS/cm) were found in galvanized tank samples for different storing periods while the lowest mean values (0.58±0.06 μS/cm and 1.04±0.06 μS/cm) were recorded in aluminum tank samples

In this paper a two dimensional numerical simulation have been applied using
MATLAB program for generating Fraunhofer diffraction pattern from different
apertures. This pattern is applied for three types of apertures, including, circular,
square, and rectangular functions, and it's could be generated any wavelength in the
visible light. The studying demonstrated the capability and the efficiency of optical
imaging systems to observe a point source at very long distance. The circular
aperture shows better results across the shape of Fraunhofer pattern and optical
transfer function (otf). Also, the minimum values of the normalized irradiance of
different diffracted apertures have been computed at different dimension

  Soil is a crucial component of environment. Total soil analysis may give information about possible enrichment of the soil with heavy metals. Heavy metals, potentially contaminate soils, may have been dumped on the ground. The concentrations of soil heavy metals (Cd, As, Pb, Cr, Ni, Zn and Cu) were measured in three zones thought to be deeply contaminated at different depths (5, 25, 50 cm) at Ibn Al-Haitham College. The highest concentration of heavy metals Pb (63.3ppm), Cr (90.7ppm), Ni (124ppm) and Cu (75.7ppm) were found in zone (A) location-1, where the highest concentration of Zn (111.7ppm) was found in zone (C). Cd and As were detected in small amounts in all zones.     PH value, organic matters, carbonat

Frequently, Load associated mode of failure (rutting and fatigue) as well as, occasionally, moisture damage in some sections poorly drained are the main failure types found in some of the newly constructed road within Baghdad as well as other cities in Iraq. The use of hydrated lime in pavement construction could be one of the possible steps taken in the direction of improving pavement performance and meeting the required standards. In this study, the mechanistic properties of asphalt concrete mixes modified with hydrated lime as a partial replacement of limestone dust mineral filler were evaluated. Seven replacement rates were used; 0,0.5, 1, 1.5, 2, 2.5 and 3 percent by weight of aggregate. Asphalt concrete mixes were prepared at their

Mandali Basin is located between latitudes (33◦ 39 '00 "- 33◦ 54' 55") to the north and longitudes (45◦ 11 '00 "- 45◦ 40' 00") to the east, eastern Diyala province. The research study attributes hydrochemical properties groundwater upper part of the Mandali basin for 20 wells through the data from the analysis of the hydrological information bank of the General Directorate for drilling water wells 2007, hydrochemical study of the water tube wells for two seasons showed water surplus season (February) and season the water deficit (August) It's water colorless, odorless dominated by sulfate ion and sodium, and through hydrochemical formula and the type of water was found that most of the water area of study is the sodium sulfate ty

The main objective of present work is to describe the feasibility of friction stir welding (FSW) for
joining of low carbon steel with dimensions (3 mm X 80 mm X 150 mm). A matrix (3×3) of welding
parameters (welding speed and tool rotational speed) was used to see influence of each parameter on
properties of welded joint .Series of (FSW) experiments were conducted using CNC milling machine
utilizing the wide range of rotational speed and transverse speed of the machine. Effect of welding
parameters on mechanical properties of weld joints were investigated using different mechanical tests
including (tensile and microhardness tests ). Micro structural change during (FSW) process was
studied and different welding zones

       The surface properties of mixtures of a nonionic surfactant Tween 80 (Tw 80) and a cationic drug, diphenhydramine HCl (DPH) have been investigated. This was done by calculating the surface excess concentration (Γ_max), minimum molecular area (A_min), surface pressure at the CMC (ᴨ_cmc), Gibbs Free Energy of adsorption (ΔG°_ads), Gibbs free energy of micellization (ΔG°_m), the standard enthalpy of micellization (ΔH°_m), and the standard entropy of micellization (ΔS°_m). The calculation was performed using the surface tension in the temperature range of 293-323 K with the variation of surfactant concentration to determine the crit

     Neutron differential-elastic and inelastic scattering cross-sections of Yttrium-89 isotope were calculated at energies 8,10,12,14, and 17 MeV, at angles distributed between 20^o and 180^o in the center of mass frame. The obtained results data were interpreted using a spherical optical potential model and Eikonal approximation, to examine the effect of the first-order Eikonal correction on the effective potential. The real and imaginary parts of optical potential were calculated. It was found that the nominal imaginary potential increase monotonically while the effective imaginary one has a pronounced minimum around r = 6fm and then increases. The analysis of the relative energy of the projectile and reaction
