Study of the Impact of Unsteady Squeezing Magnetohydrodynamics Copper-Water with Injection-Suction on Nanofluid Flow Between Two Parallel Plates in Porous Medium
...Show More Authors

      In this article,  the existence of thermal radiation with Copper- water nanofluid, the effect of heat transfer in  unsteady magnetohydrodynamics (MHD) squeezing and suction-injection on the flow between parallel plates( porous medium) are studied. Rosseland approximation and   the radiation of  heat flux are used to depict the energy equation. The set of ordinary differential equations  with  boundary conditions are analytically resolved by applying a new approach method (NAM). The influences of thermal field and physical parameters on dimensionless flow field  have been displayed in tabular and graphs form. The presented results show that the heat transfer coefficient is reduced by the thermal radiation coefficient increases and  the absolute values of the skin friction coefficients are enhanced with the magnetic amplification parameter. Regularly, the present outcomes discern that the parameters of the injection-suction coefficient are both the  temperature and velocity profiles decline.

Influence of pressure and temperature on CO2-nanofluid interfacial tension: Implication for enhanced oil recovery and carbon geosequestration
...Show More Authors

Nanoparticles (NPs) based techniques have shown great promises in all fields of science and industry. Nanofluid-flooding, as a replacement for water-flooding, has been suggested as an applicable application for enhanced oil recovery (EOR). The subsequent presence of these NPs and its potential aggregations in the porous media; however, can dramatically intensify the complexity of subsequent CO2 storage projects in the depleted hydrocarbon reservoir. Typically, CO2 from major emitters is injected into the low-productivity oil reservoir for storage and incremental oil recovery, as the last EOR stage. In this work, An extensive serious of experiments have been conducted using a high-pressure temperature vessel to apply a wide range of CO2-pres

Effect of an inclined magnetic field on peristaltic flow of Bingham plastic fluid in an inclined symmetric channel with slip conditions
...Show More Authors

This paper studies the influence of an inclined magnetic field on peristaltic transport of incompressible Bingham plastic fluid in an inclined symmetric channel with heat transfer and mass transfer. Slip conditions for heat transfer and concentration are employed. The formulation of the problem is presented through, the regular perturbation technique for small Bingham number Bn is used to find the final expression of stream
function, the flow rate, heat distribution and concentration distribution. The numerical solution of pressure rise per wave length is obtained through numerical integration because its analytical solution is impossible. Also the trapping phenomenon is analyzed. The effe

Underwriting policy and its impact on the productivity of the life insurance portfolio: Analytical study in the "Iraqi General Insurance Company
...Show More Authors

The research aims to study the basic concepts of the underwriting policy with its various indicators. The researcher studies the underwriting policy with its various indicators (sex, health status, age of the insured, insurance amount, The method of acceptance, payment method, and duration of insurance) where each of these indicators constitute an important factor in the productivity of life insurance policies, where the productivity of life insurance policies face many difficulties because insurance is a service and not a tangible material commodity and its benefits and not current. Therefore, the life insurance company needs to use a prudent underwriting policy so as not to endanger its financial position due to the expansion of the un

The Water Footprint and Virtual Water and Their Effect on Food Security in Iraq
...Show More Authors
Abstract<p>The study aimed to explaining the concepts of water footprint and virtual water and how these two concepts could use to achieve water savings at the local level to meet the water supply deficit in Iraq, which is expected to increase in the coming years and influence of that on food security in Iraq by using these concepts when drawing production, irrigated and import plans in Iraq. The study aimed to studying the water footprint and virtual water and their impact on the foreign trade for wheat and rice crops during the period 2000-2022 and estimating the most important indicators of virtual water and the water footprint of the study crops due to the importance of these criteria in det</p> ...

A Vehicle ID identification Architecture: A Parallel-Joining WSN Algorithm
...Show More Authors

Several remote sensor network (WSN) tasks require sensor information join. This in-processing Join is configured in parallel sensor hub to save battery power and limit the communication cost. Hence, a parallel join system is proposed for sensor networks. The proposed parallel join algorithm organizes in section-situated databases. A novel join method has been proposed for remote WSNs to limit the aggregate communication cost and enhance execution. This approach depends on two procedures; section-situated databases and parallel join algorithm utilized to store sensor information and speed up processing respectively. A segment arranged databases store information table in segmented shrewd. The Parallel-Joining WSN algorithm is effectively

On the Connection between the Dynamical System and the Ellis Compactification with Transitive Pointed System
...Show More Authors

In this paper, some relations between the flows and the Enveloping Semi-group were studied. It allows to associate some properties on the topological compactification to any pointed flows. These relations enable us to study a number of the properties of the principles of flows corresponding with using algebric properties. Also in this paper proofs to some theorems of these relations are given.

Studies on the Relationship Between Chromium(III) ion and Thyroid Peroxidase Activity in Sera of Patients with Thyroid Dysfunction
...Show More Authors

   The  objective of this study was to determine the concentration of trace element chromium(III) and thyroid peroxidase activity in human serum , and    to find a relationship between the concentration of chromium(III) and thyroid peroxidase activity in serum of patients with hypothyroidism, hyperthyroidism and healthy subjects. Serum thyroid peroxidase was measured by enzyme linked radioimmunoassay(ELISA) method and chromium determination was by atomic absorption spectrophotometer .Comparing the values of chromium concentration and thyroid peroxidase activity in both samples showed that there were significant positive correlations between chromium levels and thyroid peroxidase activity(P<0.01, r=0.11).
