The current research aims to study (the effect of strategy of analysis - synthesis duality in the collection of scientific fourth stage students and high-order thinking in Biology material). For evidence the objective of the research, the researcher formulated the following two null hypotheses: 1. There is no significant difference at the statistical level (0.05) between the average of scores of the experimental group students that will study according to the dualism strategy of analysis and structure and the average of scores of the controlled group students that will study according to the normal way in the collection. 2. There is no significant difference at the statistical level (0.05) between the average of scores of the experimental group students that will study according to the dualism strategy of analysis and structure and the average of scores of the controlled group students that will study according to the normal way to test high-order thinking. A current research was Identified by choosing scientific fourth stage students in the governmental diurnal secondary schools which obey to Baghdad education directorate / the first Karkh of studious year (2014- 2015), and among these schools the researcher selected Ajnadayn secondary of girls as a purposive sample. To achieve the aim of research, the researcher used experimental design a partial control, and was selected two divisions of the scientific fourth stage randomly, one of them represent the experimental group and another the controlled group. The sum of research sample was 69 students, 34 students of them in the experimental group and 35 students in the controlled group .The two groups of search were tested by four variables (the time age measured by months, scores of biology material in the test of end of the first course, the test of intelligence, and the scores of test of previous biology information) in addition adjust the other variables, also the scientific material was defined with the last five chapters of the Book of Biology which is scheduled to teach of studious year (2014- 2015). The behavioral objectives were formulated of these chapters and numbered 256 behavioral objective represented to six levels of Bloom's Taxonomy in the knowledge field (remember, absorbing, application, analysis, structure, and evaluation). The tutorial plans were prepared for the two groups of research and numbered 22 plans for each group. The researcher taught herself the two groups during the period of the experiment, which continued 11 weeks of the second semester of the academic year (2014-2015). With respect to research tools, the researcher used one tool for each dependent variable, as prepared collection test of last five chapters of the book of Biology of the scientific fourth stage consisted of 47 items represented the substantive questions, as well as the researcher adopted test of study in high-order thinking consisting of 30 items represented in the two types of questions: 15 objective paragraphs and 15 essay paragraphs, were checking the veracity of tools through articles on a group of arbitrators, have been applied to investigational samples one of them to see how clear paragraphs and time of answer and the other was for the purpose of test statistically analyzed by extracting Alsiakeomtraha characteristics, in addition to the extraction of the stability for both tests. After the end of the experiment, the two tools were applied on groups of search, then the students, answers were corrected and they were treated statistically, and the results were as the following: 1. There are statistically significant differences in favor of the experimental group in the collection test and the size of the average effect of the independent variable was (0.63). 2. There are statistically significant differences in favor of the experimental group in the high-order thinking test and the size of the average effect of the independent variable was (0.5). The results indicated that there is a positive effect of teaching by strategy of analysis – synthesis duality on the collection and the high-order thinking, and based on that the researcher put a set of conclusions, recommendations, suggestions.

Local Dependence for Bivariate Weibull Distributions Created by Archimedean Copula
...Show More Authors

In multivariate survival analysis, estimating the multivariate distribution functions and then measuring the association between survival times are of great interest. Copula functions, such as Archimedean Copulas, are commonly used to estimate the unknown bivariate distributions based on known marginal functions. In this paper the feasibility of using the idea of local dependence to identify the most efficient copula model, which is used to construct a bivariate Weibull distribution for bivariate Survival times, among some Archimedean copulas is explored. Furthermore, to evaluate the efficiency of the proposed procedure, a simulation study is implemented. It is shown that this approach is useful for practical situations and applicable fo

A Comparative Study on the Double Prior for Reliability Kumaraswamy Distribution with Numerical Solution
...Show More Authors

This work, deals with Kumaraswamy distribution. Kumaraswamy (1976, 1978) showed well known probability distribution functions such as the normal, beta and log-normal but in (1980) Kumaraswamy developed a more general probability density function for double bounded random processes, which is known as Kumaraswamy’s distribution. Classical maximum likelihood and Bayes methods estimator are used to estimate the unknown shape parameter (b). Reliability function are obtained using symmetric loss functions by using three types of informative priors two single priors and one double prior. In addition, a comparison is made for the performance of these estimators with respect to the numerical solution which are found using expansion method. The

...Show More Authors

       Optical properties and surface morphology of pure and doped Polystyrene films with different divalent metals of Zn, Cu and Sn and one concentration percentage have been studied. Measurements of UV-Vis spectrophotometer and AFM spectroscopy were determined. The absorbance, transmittance and reflectance spectrums were used to study different optical parameters such as absorption coefficient, refractive index, extinction coefficient and energy gap in the wavelengths rang 200-800nm. These parameters have increased in the presence of the metals. The change in the calculated values of energy gaps with doping metals content has been investigated in terms of PS matrix structural modification. The value of opt

Numerical Solutions of Two-Dimensional Vorticity Transport Equation Using Crank-Nicolson Method
...Show More Authors

This paper is concerned with the numerical solutions of the vorticity transport equation (VTE) in two-dimensional space with homogenous Dirichlet boundary conditions. Namely, for this problem, the Crank-Nicolson finite difference equation is derived.  In addition, the consistency and stability of the Crank-Nicolson method are studied. Moreover, a numerical experiment is considered to study the convergence of the Crank-Nicolson scheme and to visualize the discrete graphs for the vorticity and stream functions. The analytical result shows that the proposed scheme is consistent, whereas the numerical results show that the solutions are stable with small space-steps and at any time levels.

Abstract :

    In view of the fact that high blood pressure is one of the serious human diseases that a person can get without having to feel them, which is caused by many reasons therefore it became necessary to do research in this subject and to express these many factors by specific causes through studying it using (factor analysis).

  So the researcher got to the five factors that explains only 71% of the total variation in this phenomenon is the subject of the research, where ((overweight)) and ((alcohol in abundance)) and ((smoking)) and ((lack of exercise)) are the reasons that influential the most in the incidence of this disease.

Relationship phonetics and musicology at the Ikhwan Al- Safa and at al – Farabi
...Show More Authors

Phonetics has close relevance with Musicology; in this study I decided explaining the interlinkages and harmony between Phonetics and Musicology. Linguists preceded philosophers in an attempt to link Phonetics with Musicology; the 1st serious attempt to link Phonetics with Musicology was done by Ibn Jeny (Dead 392 IC), but the real attempt is found with Farabi through his book under title Al Musiqa Al Kabeer, he defined music and link it with tune and relation between melody and tone, This is the same as pointed out by Ikhwan Al Safa who followed the doctrine of al-Farabi, their attention was with music and link it with phoneme, as they made music independent science, and they created special mathematics rules for it. Melody in music can
