The Early-Middle Miocene succession in Iraq is represented by the Serikagni, Euphrates and Dhiban formations, which deposited during the Early Miocene. The Jeribe and Fatha successions were deposited during Middle Miocene age. This study includes microfacies analysis, depositional environments, sequence stratigraphy and basin development of Early – middle Miocene in Hamrin and Ajeel oil fields and Mansuriyha Gas Field. The study area includes four boreholes in three oil fields located in central Iraq: Hamrin (Hr-2) and Ajeel (Aj-13, and 19) oil feilds, and Mansuriyha (Ms-2) Gas Field. Five facies associations were distinguished within the studied fields: deep marine, slop, platform-margin, open marine, restricted interior platform, and evaporitic interior platform. The facies associations interpreted were based on texture and fauna. Deep marine facies association consists of planktonic foraminifera wackestone, it was observed in well Ms–2. Slope environment association is observed in Euphrates Formation in Hamreen-10, and it represented by bioclastic – planktonic mudstone – wackestone. The open marine association is observed in all studied wells in particular in Jeribe and Euphrates formations, and it includes bioclastic mudstone-wackestone, bioclastic peloidal wackestone-packestone and bioclastic foraminiferal wackestone- packestone. While the restricted interior platform association is dominated in all studied wells, it consists of ooidal packstone, foraminiferal peloidal packstone, dolomitic lime mudstone, dolomititic and evaporitic peloidal wackestone-packstone. In Ajil Oil Field the studied succession is consisting of two sequences (C1 and C2). The fist sequence (C1) was started with transgressive system tract (TST) reflected by open marine occupies the lower part of Euphrates Formation, the TST bounded below by SB and above by MFS. The second sequence (C2) was started with TST which is observed in the lower part of Jeribe Formation, represented by evaporitic and restricted interior platform. In Hamrin Oil Field, this succession is started with thin transgressive system tract (TST) as C1 reflected by toe of slope and it occupied a bit of lower part of Euphrates Formation. The highstand system tract (HST) is divided to five cycles (CE1, CE2, CE3, CE/Dh and CDh). Sequence C2 was started with relatively thin transgressive system tract (TST) occupies the lower part of Jeribe Formation represented by open marine environment. Two sequences are observed in Mansuriya Gas Field (C1 and C2). Sequence C1 started with thin transgressive system tract (TST) bounded below by SB1 and above by MFS which is corresponding with conformable boundary that separated between Serikagni Formation and Dhiban. Contrary, the second sequence (C2) was started with relatively thin transgressive system tract (TST) occupies the lower and middle parts of Jeribe Formation represented by restricted interior platform environment.
Experiments research is done to determine how saturated stiff clayey soil responds to a single impulsive load. Models made of saturated, stiff clay were investigated. To supply the single pulse energy, various falling weights from various heights were tested using the falling weight deflectometer (FWD). Dynamic effects can range from the major failure of a sensitive sensor or system to the apparent destruction of structures. This study examines the response of saturated stiff clay soil to a single impulsive load (vertical displacement at the soil surface below and beside the bearing plates). Such reactions consist of displacements, velocities, and accelerations caused by the impact occurring at the surface depth induced by the impact loads
... Show MoreThis study offers numerical simulation results using the ABAQUS/CAE version 2019 finite element computer application to examine the performance, and residual strength of eight recycle aggregate RC one-way slabs. Six strengthened by NSM CFRP plates were presented to study the impact of several parameters on their structural behavior. The experimental results of four selected slabs under monotonic load, plus one slab under repeated load, were validated numerically. Then the numerical analysis was extended to different parameters investigation, such as the impact of added CFRP length on ultimate load capacity and load-deflection response and the impact of concrete compressive strength value on the structural performance of
... Show MoreThis study presents, for the first time, an innovative Jet Plasma-assisted technique for the green synthesis of TiO₂@Ag core–shell nanoparticles using chard leaf extract as a natural reducing and stabilizing agent. The Jet Plasma provides a highly energetic environment that accelerates nucleation and core–shell formation at low temperatures without toxic precursors. The synthesized nanoparticles exhibited uniform and stable structures, as confirmed by comprehensive characterization techniques including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), ultraviolet–visible (UV–Vis) spectroscopy, transmission electron microscopy (TEM), and zeta potential analysis. XRD patterns confirmed the crystalline anatase
... Show MoreWe aimed to obtain magnesium/iron (Mg/Fe)-layered double hydroxides (LDHs) nanoparticles-immobilized on waste foundry sand-a byproduct of the metal casting industry. XRD and FT-IR tests were applied to characterize the prepared sorbent. The results revealed that a new peak reflected LDHs nanoparticles. In addition, SEM-EDS mapping confirmed that the coating process was appropriate. Sorption tests for the interaction of this sorbent with an aqueous solution contaminated with Congo red dye revealed the efficacy of this material where the maximum adsorption capacity reached approximately 9127.08 mg/g. The pseudo-first-order and pseudo-second-order kinetic models helped to describe the sorption measure
The δ-mixing of γ-transitions in 70As populated in the 32 70 70 33 Ge p n As (, ) γ reaction is calculated in the present work by using the a2-ratio methods. In one work we applied this method for two cases, the first one is for pure transition and the sacend one is for non pure transition, We take into account the experimental a2-coefficient for previous works and δ -values for one transition only.The results obtained are, in general, in a good agreement within associated errors, with those reported previously , the discrepancies that occur are due to inaccuracies existing in the experimental data of the previous works.
Hepatitis C virus (HCV) is a liver disease that affects14 million people. Feasible research was conducted for identifying the genotypes and allele frequency of some single nucleotide polymorphisms (SNPs) of the IL-28β genes and their predictive role in disease incidence in Iraqi patients. The SNPs (rs28416813, rs4803219, rs11881222, and rs8103142) of IL-28β have been associated with susceptibility to several diseases. Ninety eight (98) HCV patients were included in this research; with average age ± SE (42.28 ± 3.44) years. Also, 80 healthy people (with average age ± SE (29.40 ± 2.84) years) were included as a control group. The SNPs were detected by allele-specific PCR (polymerase chain reaction) using specific primers. The re
