Modeling and Analyzing the Influence of Fear on the Harvested Modified Leslie-Gower Model

A modified Leslie-Gower predator-prey model with a Beddington-DeAngelis functional response is proposed and studied. The purpose is to examine the effects of fear and quadratic fixed effort harvesting on the system's dynamic behavior. The model's qualitative properties, such as local equilibria stability, permanence, and global stability, are examined. The analysis of local bifurcation has been studied. It is discovered that the system experiences a saddle-node bifurcation at the survival equilibrium point whereas a transcritical bifurcation occurs at the boundary equilibrium point. Additionally established are the prerequisites for Hopf bifurcation existence. Finally, using MATLAB, a numerical investigation is conducted to verify the validity of the theoretical analysis and visualize the model dynamics.

The Use of Cubic Bezier Interpolation, Biorthogonal Wavelet and Quadtree Coding to Compress Color Images

In this paper, an efficient method for compressing color image is presented. It allows progressive transmission and zooming of the image without need to extra storage. The proposed method is going to be accomplished using cubic Bezier surface (CBI) representation on wide area of images in order to prune the image component that shows large scale variation. Then, the produced cubic Bezier surface is subtracted from the image signal to get the residue component. Then, bi-orthogonal wavelet transform is applied to decompose the residue component. Both scalar quantization and quad tree coding steps are applied on the produced wavelet sub bands. Finally, adaptive shift coding is applied to handle the remaining statistical redundancy and attain e

Facies Architecture And Depositional Marine Systems of the Yamama Formation in Selected Wells, Southern Iraq

      The Yamama Formation is characterized by a wide geographic extension of southern Iraq. Microfacies analysis of this formation was studied in six wells distributed in six fields: Fayhaa, Sindbad, Siba, Zubair, Ratawi and West Qurna. This research aims to determine paleoenvironments by diagnosing biofacies and lithofacies. Miscellaneous marine fauna of foraminifera and calcareous algae, mainly green algae (dasycladacean.) and skeletal bioclasts from gastropods, pelecypods, bryozoans, sponge spicules, and echinoderms were found. Petrographic studies and well logs interpretations led to the identification of five main Microfacies ( Mudstone, Wackestone, Packestone, Grainestone and Rudstone and twelve submicrofacies (Foraminiferal-

Application of the updated DeLone and McLean IS success method to investigate e-CRM effectiveness

Information and communication technology has a significant influence on employee procedures. Businesses are investing in e-CRM technologies, yet it is difficult to assess the performance of their e-CRM platforms. The DeLone and McLean Information Systems Success framework can be modified to the current e-CRM assessment difficulties. The new framework's different aspects provide a concise framework for organizing the e-CRM key metrics identified in this study. The purpose of this study is to apply and verify that the Updated DeLone and McLean IS Model can be employed to explain e-CRM adoption among employees, along with the extended Updated DeLone and McLean Model with its five output factors, namely system quality, service quality,

Administrative Corruption in Contemporary Systems and the Role of Islamic Administrative Organization in Combating It

Administrative corruption is a concept that includes the abuse of entrusted power for personal benefit. It has become a prominent contemporary problem affecting all government systems around the world. It involves widespread harm and negative impact on progress and development, and is considered a threat at the international level because it impedes development programs and undermines the interests of the public. Administrative corruption threatens modern governments, distorts public policies, causes weaknesses in the oversight system, and affects the distribution of resources.

Islamic law is considered a pioneer in diagnosing this type of problem, as it provides clear solutions to eliminate administrative corruption, as Islamic

The Relationship Between Infertility and Infection with Clarithromycin Resistant Strain of Helicobacter Pylori in Iraq

The relationship between infertility and Helicobacter pylori infection was investigated; samples from thirty-five infertile patients (aged 20-49 years) were collected from Kamal Al-Samaraei hospital , Baghdad, Iraq during the period from the first of February until April 2018. These patients were compared with 10 apparently fertile individuals who served as a control. The study was carried out to detect the DNA of H.pylori in both serum and seminal fluid of male infertile patients and for the control group by Real-Time Polymerase Chain Reaction (RT-PCR) technique. The results revealed that there was a significant difference (P<0.01) in the detection of DNA of H.pylori between pa

Criminal policy in the domain of freezing terrorist funds and its role in addressing crime

It emerged as the issue of counter - terrorism recently on international levels and internal as a result of the increase in terrorist acts and committed in various countries، resulting in loss of lives and money so concerned with countries in this issue and the need to combat and eliminate the negative destructive effects that have become affect the prestige and integrity of States and stability.

 As a result followed criminal legislation at the international and domestic incriminatory policy may be varied somewhat in order to confront terrorist crimes by criminalizing certain acts that constitute the crime of terrorist At the international level ، several global and regional international conventions held to combat this p
