Modeling and Stability of Lotka-Volterra Prey-Predator System Involving Infectious Disease in Each Population

In this paper, a mathematical model consisting of the prey- predator model with disease in both the population is proposed and analyzed. The existence, uniqueness and boundedness of the solution are discussed. The existences and the stability analysis of all possible equilibrium points are studied. Numerical simulation is carried out to investigate the global dynamical behavior of the system.

Chronic Kidny Disease and Risk of coronary Artery Disease,Aprospective study

AbstractBackground:Reduced glomeular filtration rate isassociated with increasedmorbidity in patientswith coronary arterydisease.Objectives :To analyze the declining eGFR andmortality risks in a patients with Chronic KidneyDisease and have had Coronary Artery Diseaseincluding risk factors .Patientsand Methods:The study included (160)patientsbetween the ages of 16 and 87years.Glomerular filtration rate was estimated (eGFR)using the Modification of Diet in Renal Diseaseequationand was categorized in the ranges<60 mL· min−1 per 1.73 m2and≥ 60 ml/min/1.73 m2.Baseline risk factors were analyzed by category ofeGFR,.The studied patients in emergencydepartment, were investigatedusing Coxproportional hazard models adjusting for traditiona

Congenital coronary anomalies in Iraqi adult population

Background: Geographic variations in the incidence of different congenital coronary anomalies are well known, but infrequently studied in the Iraqi population.
Recognition of coronary anomalies is important in patients undergoing coronary arteriogrphy; coronary interventions and cardiac surgery .Variation in the frequency of primary congenital coronary anomalies may possibly have a genetic background. 
Patients and methods: Three thousands adult patients underwent diagnostic coronary angiography at two cardiac centers in Baghdad between January 2003 to March 2006. Their angiographic films were reviewed by at least two experts in coronary angiographic study.
Results: Among 3000 adult patients wh

HLA Diversity in Iraqi Population: Molecular Typing

Background: Different populations show various human leukocyte antigens (HLA). Data of HLA distribution is important in field of vaccines, therapy, Anthropology and for future studies of disease association with HLA.
Objective: To highlight on frequency of HLA alleles in Iraqi population by using molecular technique.
Patients and methods: Two hundred individuals were genotyped for HLA class I and II alleles by polymerase chain reaction sequence-specific oligonucleotides (PCR-SSO).
Results: This study observed that the alleles with highest frequency were: [A*02(27.75%,A*01(10.75%,A*03(8%),B*51(17.75%),B*35(9%),B*07(6%),C*04(26.75%),C*07(20.25%),C6*0(9.75%),DRB1*02(17.5%,DRB1*07(17%),DRB1*04(14.75%)DQB1*01(25.5%),DQB1*03(21.75%),D

Model Estimated Building in Finite Population Sampling

Abstract

The population is sets of vocabulary common in character or characters and it’s study subject or research . statistically , this sets is called study population (or abridgement population ) such as set of person or trees of special kind of fruits or animals or product  any country for any commodity through infinite temporal period term ... etc.

The population maybe finite if we can enclose the number of its members such as the students of finite school grade . and maybe infinite if we can not enclose the number of it is members such as stars or aquatic creatures in the sea . when we study any character for population the statistical data is concentrate by two metho

Linear and Non-Linear Stability Analysis for Thermal Convection in A Bidispersive Porous Medium with Thermal Non-Equilibrium Effects: Linear and non-linear stability analysis

     The linear instability and nonlinear stability analyses are performed for the model of bidispersive local thermal non-equilibrium flow. The effect of local thermal non-equilibrium on the onset of convection in a bidispersive porous medium of Darcy type is investigated.  The temperatures in the macropores and micropores are allowed to be different. The effects of various interaction parameters on the stability of the system are discussed. In particular, the effects of the porosity modified conductivity ratio parameters,  and , with the int

2. detect the consumption culture among the population in the city of Erbil.
3. Identify the GATT consumer protection and rights.
The most important results:
1. that there is variation in the answers of respondents about keep up with modernity in the basic consumption (necessary), it swallowed the proportion of yes answers about keep up with modernity in food consumption (72%), and is an indication of growing consumer awareness of the individual in the side of nutrition.

The effect of surlactin produced by Lactobacillus acidophilus on eye infectious bacteria in rabbits

Twenty five vaginal swabs from outpatients' healthy women were collected from Kamal Al-Samarai Hospital, Baghdad, to isolate and identify of Lactobacillus acidophilus. Three isolates were diagnosed as L. acidophilus which represents 15% of the total number of lactic acid bacterial (LAB) isolates; other LAB types represent 65% (20 isolates).The ability of L. acidophilus to produce surlactin was detected after measuring its biological activity to inhibit the adhesion of biofilm formed by Pseudomonas aeruginosa to surfaces using test tube method. It was found that all isolates were able to produce surlactin but the activity of surlactin was varying in each isolate. Surlactin produced by isolates 1 and 13 was the most effective. Biological appl

Genetic and Phenotypic Variations in Phenylthiocarbamide Bitter Taste Receptors in Iraqi Population

     Bitter substances are identified by protein receptors located on surface of taste cell membranes. Mutational polymorphism of the bitter taste receptor (TAS2R38) is a significant determinant in phenylthiocarbamide (PTC) threshold perception. This research's objectives were to find TAS2R38 polymorphisms in Iraqi people and investigate any correlations between genotype and the PTC taste sensitivity. Bitterness sensitivity was determined by assessing the capacity to differentiate and the responsiveness to a representative strip of PTC. Cheek cells samples were collected for DNA extraction, PCR amplification and genotyping. PCR was performed to amplify the short region of the TAS2R38 gene containing the initial polymorphisms of inter

Discrete Optimal Control Mathematical Model of Diabetes Population

In this work, nonlinear diabetes controlled model with and without complications in a population is considered. The dynamic behavior of diabetes in a population by including a constant control is studied and investigated. The existence of all its possible fixed points is investigated as well as the conditions of the local stability of the considered model are set. We also find the optimal control strategy in order to reduce the number of people having diabetes with complications over a finite period of time. A numerical simulation is provided and confirmed the theoretical results.

Solution of two-dimensional fractional order volterra integro-differential equations

In this paper, our aim is to study variational formulation and solutions of 2-dimensional integrodifferential equations of fractional order. We will give a summery of representation to the variational formulation of linear nonhomogenous 2-dimensional Volterra integro-differential equations of the second kind with fractional order. An example will be discussed and solved by using the MathCAD software package when it is needed.
