Effects of Ultrasonic Treatment and Hydrogen Donor Addition on the Viscosity of Iraqi Heavy Crude Oil
...Show More Authors

The current investigation examines the combined impacts of ultrasonic radiation and hydrogen donors on the viscosity of heavy crude oil. The impact of exposure time, power, duty cycle, and temperature on the viscosity of Iraqi heavy crude oil with 20.32 API was studied. Also, the viscosity of the oil samples, which were mixed with a hydrogen donor (decalin) and subjected to ultrasonic treatment under optimal conditions, was examined to evaluate the combined impact of ultrasonic radiation and hydrogen donor on the viscosity of crude oil. The viscosity experienced a decrease of 52.34% at 2 min of irradiation, 360 W ultrasonic power, 0.8 duty cycle, 35 ⁰C, and 8vol% decalin. To validate the outcomes of the experiments, asphaltene content, sulfur content, API gravity, and distillation tests were conducted on both the original and final samples (under optimal conditions). The concentrations of asphaltene and sulfur exhibited a drop of 37.51% and 35.04%, respectively. The results show that cavitation, a heat phenomenon, and the mechanical impact of ultrasound may help break up long carbon chains and reduce the size of asphaltene aggregates, which causes the crude oil's viscosity to drop. Moreover, the findings demonstrated that the simultaneous application of ultrasound and hydrogen donor yielded the most significant decrease in oil viscosity compared with untreated crude oil or treated just with ultrasonic waves.

Representations of the ego and the other In the Iraqi feminist novel
...Show More Authors

The other is a problematic concept and can be achieved only by the existence of difference and differentiation between human groups in views and views, the other is out of the ego, which is different religiously, politically, socially, culturally, place and language.
We take from the Iraqi feminist novel analytical field to reflect the image of the other in the novelist world, and the models chosen for the study are: the novel granddaughter of American novelist Anaam Kjie Ji, and novel how the sky seemed close to the novelist Batoul al-Khudairi, and novel when you wake up the smell of novelist Dni Ghali, and the rope of the umbilical and the novel Shufuni Shufuni The novel by Samira Al-Manea, the novelist of the novelist Alia Mamdouh,

The Adsorption of Some Trace Heavy Metals from Aqueous Solution Using Non Living Biomass of Sub Merged Aquatic Plant Ceratophyllum demersum
...Show More Authors

Heavy metals contamination in aquatic ecosystems is considered one of the most important threats of aquatic life. Submerge aquatic plants Ceratophyllum demersum in its non living form used for the removal of trace elements. This article studied the ability of the fine powder of C.demersum for the removal of some heavy metals (HM) like copper, cadmium, lead and chrome from aqueous solution with in variable experimental factors. The study occupy two treatments the first included different hydrogen ions pH within a range of 4, 5,6and 8 with a constant HM concentration (1000 ppm).While the second treatment represented by using variable HM concentrations within a range of (250,500,750and 1000 ppm) with a constant pH=7.In both treatments the a

The Synergic Effects of Mineral Admixtures in Ternary Blended Cement: A Review
...Show More Authors

In the last decades, using mineral admixture in concrete became very necessary to improve concrete properties and reduce CO2 emissions associated with the cement production process. Subsequently, more sustainable concrete can be obtained.  Ternary blended cement containing two different types of mineral admixture can achieve ambitious steps in this trend. In this research, the synergic effects of mineral admixtures in ternary blended cement and its effects on concrete fresh properties, strength, durability, and efficiency factors of mineral admixture in ternary blended cement, were reviewed. The main conclusion reached after reviewing many literature pieces is that the concrete with ternary blended cement

Multicomponent Equilibrium Isotherms and Kinetics Study of Heavy Metals Removal from Aqueous Solutions Using Electrocoagulation Combined with Mordenite Zeolite and Ultrasonication
...Show More Authors

Combining different treatment strategies successively or simultaneously has become recommended to achieve high purification standards for the treated discharged water. The current work focused on combining electrocoagulation, ion-exchange, and ultrasonication treatment approaches for the simultaneous removal of copper, nickel, and zinc ions from water. The removal of the three studied ions was significantly enhanced by increasing the power density (4–10 mA/cm2) and NaCl salt concentration (0.5–1.5 g/L) at a natural solution pH. The simultaneous removal of these metal ions at 4 mA/cm2 and 1 g NaCl/L was highly improved by introducing 1 g/L of mordenite zeolite as an ion-exchanger. A remarkable removal of heavy metals was reported

The Effect of AcceleDent® Device on Both Gingival Health Condition and Levels of Salivary Interleukin-1-βeta and Tumor Necrosis Factors-Alpha in Patients under Fixed Orthodontic Treatment
...Show More Authors

Background: Orthodontic tooth movement is characterized by tissue reactions, which consist of an inflammatory response in periodontal ligament and followed by bone remodeling in the periodontium depending on the forces applied. These processes trigger the secretion of various proteins and enzymes into the saliva.The purpose of this study was to evaluate the activity of alkaline phosphatase (ALP) in saliva during orthodontic tooth movement using different magnitude of continuous orthodontic forces. Materials and Methods: Thirty orthodontic patients (12 males and 18 females) aged 17-23 years with class II division I malocclusion all requiring bilateral maxillary first premolar extractions were randomly divided into three groups according to t

A new generation of cable grade poly(vinyl chloride) containing heavy metal free modifier
...Show More Authors
Abstract<p>Many additives are used to improve the performance of cables in terms of increasing their flame retardancy, thermal stability, thermal conductivity, and other characteristics. Unfortunately, most of these additives contain heavy metals. Therefore, the main objective of this study is to introduce a material representing a new generation of environmentally friendly heavy metal-free stabilizers for cable grade poly(vinyl chloride) that can compete with traditional materials in terms of performance and distinctive properties. This unique additive is Oxydtron, a synthetic silicate or simply nanocement. The tests performed are rheological properties represented by a capillary rheometry analysis, limiting o</p> ... Show More
