تقويم محتوى كتاب مادة الكيمياء للصف الخامس العلمي على وفق معايير محددة
...Show More Authors

ان للمنهج المدرسي أهمية كبيرة جداً في العملية التربوية لأنه أداتها في تحقيق الأهداف التربوية المنشودة والتي تعمل على تقدم المجتمع وتطوره في مختلف الجوانب. بمعنى ان المنهج غير ثابت بل متغير ليواكب التطور والتغير الحاصل في العالم والمجتمع وهذا يعني ان المنهج المدرسي بكل عناصره والتي من ضمنها المحتوى في تطور دائم فما يصلح لفترة زمنية معينة لا يصلح لفترة زمنية قادمة مما يستلزم القيام بعملية تقويمية بشكل مستمر وخلال مدد زمنية مناسبة لتطوره. ومحتوى مادة الكيمياء كونه احد عناصر المنهج الذي يساهم في إكتساب المتعلمين المفاهيم والاتجاهات والمهارات الكيميائية التي تساعد في بناء شخصيتهم. وبما ان محتوى هذا المنهج يقدم إلى المتعلمين في مرحلة مهمة في تخصصهم العلمي الذي يعد الأساس المهم للصفوف المنتهية للمرحلة الأساسية والإعدادية والثانوية والتعليم العالي فضلاً عن محتوى منهج مادة الكيمياء للصف الخامس العلمي لم يقوم منذ فترة طويلة حسب علم الباحثة , لذا فأن هدف البحث هو تقويم محتوى منهج مادة الكيمياء للصف الخامس العلمي الذي هو العنصر الثاني من المرحلة الأولى لبناء المنهج. اما قيما يخص إجراءات البحث فقد اتبعت الخطوات التالية: يتألف مجتمع البحث من المدارس الثانوية والإعدادية والأساسية في مدينة بغداد المركز والتي تدرس مادة الكيمياء . تتألف عينة البحث : من مجتمع البحث من المدرسين والمدرسات لمادة كيمياء الصف الخامس العلمي بافتراض وجود عدد من المدرسين مساوي لعدد المدارس تم اختبار عدد منها بالطريقة العشوائية الطبقية فتم توزيع (150) استمارة بالطريقة العشوائية الطبقية مجتمع الاختصاصيين التربويين لمادة الكيمياء للصف الخامس العلمي وقد شملهم البحث جميعاً.

Notes on Weibull Distribution
...Show More Authors

Weibull Distribution is one of most important distribution and it is mainly used in reliability and in distribution of life time. The study handled two parameter and three-parameter Weibull Distribution in addition to five –parameter Bi-Weibull distribution. The latter being very new and was not mentioned before in many of the previous references. This distribution depends on both the two parameter and the three –parameter Weibull distributions by using the scale parameter (α) and the shape parameter (b) in the first and adding the location parameter (g)to the second and then joining them together to produce a distribution with five parameters.

Cybercrime and risks to children between the problems and solutions( An analytical study in the light of international, Arab and national statistics).
Lies the problem of the study to identify a new type of crime is different from the same traditional character of the crimes or what was customary since human creation up to the information revolution and we enter the era of globalization, which is also called (cyber crime) and their negative impact on all segments of society, especially children, as they the day of the most important social security threats, for all local and international communities alike , and those risks require collective action to various sectors and segments of society ,especially the educated classes in order t

The Impact Of Means Of Support On The Intention Entrepreneurial Field Research On A Sample Of Algerian Students
...Show More Authors

     The aim of this paper to study the effect of the implicit factors on the entrepreneurial spirit of the students of the Algerian university. Our structural model was proposed based on the model (Shapiro et Sokol, 1982) and the model (Ajzen, 1991). We tested it on a sample of 163 university students at the University of Algiers 3. The model consists of a set of variables (the intention of contracting as a dependent variable, structural and social educational support as independent variables). The results showed that educational and social support factors affect the entrepreneurial spirit of students more than structural support. The Applied Impacts are the enhancing of knowledge capacities of university stu

An exploratory study of history-based test case prioritization techniques on different datasets
...Show More Authors

In regression testing, Test case prioritization (TCP) is a technique to arrange all the available test cases. TCP techniques can improve fault detection performance which is measured by the average percentage of fault detection (APFD). History-based TCP is one of the TCP techniques that consider the history of past data to prioritize test cases. The issue of equal priority allocation to test cases is a common problem for most TCP techniques. However, this problem has not been explored in history-based TCP techniques. To solve this problem in regression testing, most of the researchers resort to random sorting of test cases. This study aims to investigate equal priority in history-based TCP techniques. The first objective is to implement

Corrosion Effective of Condensed Synthetic Automotive Solution Containing Selective Organic Component Mixtures on Al-alloys
...Show More Authors

Abstract

 This work involves studying the effect of adding some selective organic component mixture on corrosion behavior of pure Al and its alloys in condensed synthetic automotive solution (CSAS) at room temperature. This mixture indicates the increasing of octane number in previous study and in this study show the increasing in corrosion resistance through the decreasing in corrosion rate values.

Electrochemical measurements were carried out by potentiostat at 3 mV/sec to estimate the corrosion parameters using  Tafel extrapolation method, in addition to cyclic polarization test to know the pitting susceptibility of materials in tested medium.

The cathodic Tafel slope

Acute Toxicity of Chlorpyrifos on the Freshwater Bivalves (Unio Tigridis) and Effects on Bioindicators
...Show More Authors

A freshwater bivalve plays a crucial function in aquatic habitats as the filtered water and burrowing mussels mix the sediment, thus increasing oxygen content and making the ecosystem healthier. The aim of the study is to see how chlorpyrifos affects biochemical markers in freshwater mussel Unio tigridis. About 180 individuals per taxon and water samples were collected from the Qandil water resource on the Greater Zab River, Erbil Province, Iraq. Once arrived at the lab, the individuals were kept in aquaria with river water and an air-conditioned room Temperature: 25±2 and Light: 12h/12h and acclimatized to laboratory conditions for seven days in aged tap water. The mussel's identification molecularly and the DNA sequence of t

Influence of Cold Plasma on Sesame Paste and the Nano Sesame Paste Based on Co-occurrence Matrix
...Show More Authors

The aim of the research is to investigate the effect of cold plasma on the bacteria grown on texture of sesame paste in its normal particle and nano particle size. Starting by using the image segmentation process depending on the threshold method, it is used to get rid of the reflection of the glass slides on which the sesame samples are placed.  The classification process implemented to separate the sesame paste texture from normal and abnormal texture. The abnormal texture appears when the bacteria has been grown on the sesame paste after being left for two days in the air, unsupervised k-mean classification process used to classify the infected region, the normal region and the treated region. The bacteria treated with cold plasma, t

The Effect of Additives on The Performance of Hydrostatic Thrust Bearings
...Show More Authors

 

The paper is concerned with, the behavior of the hydrostatic thrust bearings lubricated with liquid-solid lubricants using Einstein viscosity formula, and taking into account the centrifugal force resulting from high speed.  Also studied is the effect of the bearing dimensions on the pressure, flow rate, load capacity, shear stress, power consumption and stiffness.

The theoretical results show an increase in load capacity by (8.3%) in the presence of solid graphite particles with concentration of (16%) by weight as compared with pure oil, with increasing shear stress.  .

In general the performance of hydrostatic thrust bearings improve for load carrying capacity, volume flow rate,
