اثر طريقة الملاحظات الصفية باستخدام الحاسوب( كمنشطات عقلية) في التحصيل الدراسي لمادة الفيزياء لدى طالبات الصف الأول المتوسط

The research aim to know the effect of note–taking by computer method as amentalactivators in achievement of physics subject for the first intermediate class students.

To investigate from aim of the research the research sample was chosen from the first intermediate class students in Al–mutamyzat secondary school for girls. Which belongs to the general administration for the second karkh education which randomly chosen from (9) schools for distinct female students in Baghdad. Then randomly chosen two sections form three about (80) female students at (66.667%) from total sample it’s about (120) female student in the three sections. The randomly chosen too, section (a) to represent experimental group it’s about (41) female students at (34.167%) and the section (g) represent the control group it’s about (39) female students at (32.5%) from the research society then the experimental and control groups design with apost–test was chosen the two groups have been equalization in the two variables that is (the female students g achievement in physics and mathematics subjects for mid year) and in another variable swhich effect on rocedure of the research. Then the experimental group female students was teaching by using note–taking by computer method as mentalactivators but the control female students was teaching by traditional method for physics subject before that the researcher put the special aim sand the behavior objectives in the light of bloom classification and she makes the teaching plane swhich was exposing them of specialists in physics and its teaching methods to ascertain from their validity for application. Then the esearcher prepared an achievement post-test which kind multiple–hoice with three chosen depend on the physics subjects include (38) items in the light of bloom classification by remember, understanding, and application level. It’s by using half–spilt method and the persone quation the reliability was (0.75) and correct that by using spearman–brown equation (r21) it was (0.85) the experiment was conducted in these condterm of the academic year (2012–2013). The data were statistically processed by using t-test formula for two

Unequal independent samples then the stand by hypothesis was accepted that’s there is statistic significant difference at (0.05) level between two averages for the female students which studied by using note–taking by computer method and for the female student which studied by using the traditional method in achievement for physics subject for the first intermediate class.

Then in the light of the research results the researcher commended the education mainstay and higher teaching mainstay to adoption for the note–taking by computer method to training the physics teacher to use it in their teaching and include it in the decision of the curriculum and the researcher suggested to makes imilar studies in several subjects and the stages of study to know it effect in achievement end another variables.

the Immunohistochemical Study of Stathmin-1 as A Prognostic factor In Non-small cell lung carcinoma

Abstract   

 

Background

Stathmin1 (also known as metablastin) is a major microtubule-depolymerizing protein that involved in cell cycle progression and cell motility.

 Stathmin1 has been found to be up-regulated in some cancers and correlated with cell differentiation and proliferation.  

Stathmin1 is a major cytosolic phosphoprotein that regulates microtubule dynamics and is associated with malignant phenotypes in various cancers, including non-small cell lung cancer.

 

Objective

 To evaluate the role of Immunohistochemical expression of stathmin1 in non-small

Financial investment strategies – Conceptual Framework

The investor needs to a clear strategy for the purpose of access to the financial market, that is, has a plan to increase The share of the profits thinking entrepreneur and new, and highlights the importance of this in that it sets for the investor when it goes to the market, and when it comes out of it, and at what price to buy or sell the stock, and what is the the amount of money it starts. Fortunately, he does not need to invent his own investment strategy, because over the years the development of effective methods of buying and selling, and once you understand how to work these methods investor can choose the most appropriate methods and adapted image that fit his style investment .

A comparative reading of the social and political satire in the works of Abu al-Fadl Zrui Nasrabad and Ahmad Rajab (The tadhk: خوانش تطبیقی طنز اجتماعی – سیاسی در آثار ابوالفضل زرویی نصرآباد و احمد رجب(مورد مطالعه: تذکرة المقامات زرویی و نصف كلمة احمد رجب)

           Satire is genre of the literary arts that has always been the source of human interest. Because  it is difficult to accept direct criticism, Satire appears as a literary tool in which vices, follies, abuses and shortcomings are held up to ridicule, with the intent of shaming individuals, corporations, government, or society itself into improvement. A satirical critic usually employs irony to attain this goal. Although satire is usually meant to be humorous, its greater purpose is often profitable social criticism, using wit to draw at

Use Simulation To Differentiate Between Some Modern Methods To the Model GM(1,1) To Find Missing Values And Estimate Parameters With A Practical Application

Abstract

       The grey system model GM(1,1) is the model of the prediction of the time series and the basis of the grey theory. This research presents the methods for estimating parameters of the grey model GM(1,1) is the accumulative method (ACC), the exponential method (EXP), modified exponential method (Mod EXP) and the Particle Swarm Optimization method (PSO). These methods were compared based on the Mean square error (MSE) and the Mean Absolute percentage error (MAPE) as a basis comparator and the simulation method was adopted for the best of the four methods, The best method was obtained and then applied to real data. This data represents the consumption rate of two types of oils a he

Use Generalized Pareto Survival Models to Estimation Optimal Survival Time for Myocardial Infarction Patients

The survival analysis is one of the modern methods of analysis that is based on the fact that the dependent variable represents time until the event concerned in the study. There are many survival models that deal with the impact of explanatory factors on the likelihood of survival, including the models proposed by the world, David Cox, one of the most important and common models of survival, where it consists of two functions, one of which is a parametric function that does not depend on the survival time and the other a nonparametric function that depends on times of survival, which the Cox model is defined as a semi parametric model, The set of parametric models that depend on the time-to-event distribution parameters such as

Comparison for estimation methods for the autoregressive approximations

Abstract

      In this study, we compare between the autoregressive approximations (Yule-Walker equations, Least Squares , Least Squares ( forward- backword ) and Burg’s (Geometric and Harmonic ) methods, to determine the optimal approximation to the time series generated from the first - order moving Average non-invertible process, and fractionally - integrated noise process, with several values for d (d=0.15,0.25,0.35,0.45) for different sample sizes (small,median,large)for two processes . We depend on figure of merit function which proposed by author Shibata in 1980, to determine the theoretical optimal order according to min
