Synthesis of a CoO–ZnO nanocomposite and its study as a corrosion protection coating for stainless steel in saline solution
...Show More Authors

Reaxys Chemistry database information SciVal Topics Metrics Abstract A novel CoO–ZnO nanocomposite was synthesized by the photo irradiation method using a solution of cobalt and zinc complexes and used as a coating applied by electrophoretic deposition (EPD) for corrosion protection of stainless steel (SS) in saline solution. The samples were characterized using powder XRD, scanning electron microscopy (SEM) and electrochemical polarization. It was also found that the coating was still stable after conducting the corrosion test: it contained no cracks and CoO–ZnO nanocomposites clearly appeared on the surface. SEM showed that the significant surface cracking disappeared. XRD confirmed that CoO–ZnO nanocomposites comprised CoO and ZnO phases without any impurity. The SEM images of CoO–ZnO nanocomposites revealed the average particle size (23.66 nm). The corrosion behavior of the stainless steel in saline environment in the temperature range of 298– 328 K was assessed by means of electrochemical techniques such as potentiodynamic polarization curves. The corrosion protection of the alloy increased with an increase in temperature from 99.97 to 99.99%, which indicates that the nanocomposite CoO–ZnO coating on the stainless steel surface is slightly affected by temperature. The results showed that CoO– ZnO nanocomposite provided powerful corrosion protection in saline solutions. The maximum protection efficiency was 99.99% in saline solutions at 328 K. The apparent activation energy (Ea) and pre-exponential factor (kinetic parameters) are calculated and discussed. Also, thermodynamic values such as the activation entropy (ΔS*) and activation enthalpy (ΔH*) were calculated.

Biology Textbook for Scientific Sixth Class in Iraq (A Comparative Study)
...Show More Authors

The textbook is the primary means of creativity and thinking, which has a major role in the development of the readership and mental abilities of the student. It is the basic tool in education in Iraq for the teacher and the student, which cannot be dispensed in any educational program. The current study aimed at the book of the biology of the sixth grade of science in Iraq (comparative study). It was compared to the book of biology for the twelve grade in the Kingdom of Jordan to identify the ratio of similarity and differences between them, in addition, to identify the weaknesses in the Iraq curriculum and developing appropriate solutions and suggestions to address them. The sample was represented with books of biology (six-science cla

Cathodic Protection Design Algorithms for Refineries Aboveground Storage Tanks
...Show More Authors

Storage tanks condition and integrity is maintained by joint application of coating and cathodic protection. Iraq southern region rich in oil and petroleum product refineries need and use plenty of aboveground storage tanks. Iraq went through conflicts over the past thirty five years resulting in holding the oil industry infrastructure behind regarding maintenance and modernization. The primary concern in this work is the design and implementation of cathodic protection systems for the aboveground storage tanks farm in the oil industry.

Storage tank external base area and tank internal surface area are to be protected against corrosion using impressed current and sacrificial anode cathodic protection systems. Int

A Computational Model of the Brain Cortex and Its Synchronization
...Show More Authors

Obtaining the computational models for the functioning of the brain gives us a chance to understand the brain functionality thoroughly. This would help the development of better treatments for neurological illnesses and disorders. We created a cortical model using Python language using the Brian simulator. The Brian simulator is specialized in simulating the neuronal connections and synaptic interconnections. The dynamic connection model has multiple parameters in order to ensure an accurate simulation (Bowman, 2016). We concentrated on the connection weights and studied their effect on the interactivity and connectivity of the cortical neurons in the same cortical layer and across multiple layers. As synchronization helps us to mea

Spike neural network as a controller in SDN network
...Show More Authors

The paper proposes a methodology for predicting packet flow at the data plane in smart SDN based on the intelligent controller of spike neural networks(SNN). This methodology is applied to predict the subsequent step of the packet flow, consequently reducing the overcrowding that might happen. The centralized controller acts as a reactive controller for managing the clustering head process in the Software Defined Network data layer in the proposed model. The simulation results show the capability of Spike Neural Network controller in SDN control layer to improve the (QoS) in the whole network in terms of minimizing the packet loss ratio and increased the buffer utilization ratio.

Evaluation the Structural Behavior of Lightweight Concrete-Filled Steel Tube Columns: A Review
...Show More Authors
Abstract<p>Lightweight concrete-filled tube (CFST) columns offer numerous benefits, such as reduced weight, enhanced resistance to buckling, improved structural performance, and the ability to endure cyclic loading. This study considered key research on the structural behavior of CFST columns, covering various topics, including lightweight concrete, methods of concrete placement within steel tubes, and CFST columns with and without shear connectors. The literature review reveals that while several researchers have explored the use of shear connectors as a load-transfer mechanism in CFST columns, there is no consensus on the design methodology for connector resistance. Shear connectors signifi</p> ... Show More
