...Show More Authors

تعد التجارب المختبرية من أهم الوسائل التي تمكن من فهم خصائص المواد الكيميائية وسلوكها، كما إنها الوسيلة الوحيدة لتحضير المركبات الكيميائية المختلفة. وقد أدى تطور التكنولوجيا في الوقت الحاضر إلى إستخدام أدوات وأجهزة قياس في المختبر مكنت من زيادة دقة نتائج التجارب وسرعة الحصول عليها. أن تفعيل المختبر وإجراء الأنشطة العملية يمكن أن تحقق عدة أمور منها : 1- تُنمي في الطالب مهارات التفكير العلمي ( الملاحظة ، وتحديد المشكلة، وفرض الفروض، وإختبار الفروض، وإختيار الفرض الصحيح ، الإستنتاج والتعميم ) 2- تنمية القدرة على حل المشكلات والتفكير الإبداعي . 3- تمكن الطالب من تكوين المفاهيم بدلاً من المعرفة المجردة . 4- تساعد الطالب على تكوين الميول والإتجاهات العلمية ونوع الإختصاص في المستقبل . 5- تساعد على ترسيخ المعلومة وبقاء أثر التعلم فترة أطول . 6- تكسب الطالب طرق التعامل مع الأدوات المختبرية والمواد الكيميائية والتعرف على مخاطرها عن قرب وفهم قوانين وقواعد السلامة في المختبر وتطبيقها والمحافظة على سيرالعمل والآلات والأجهزة الموجودة في المختبر. 7- بث روح التعاون بين الطلاب بين المجاميع المختبرية . ويغطي هذا الكتاب مما يحويه من المعلومات الضرورية الوافية لمساقين في الكيمياء اللاعضوية وخاصة في التعرف على الجدول الدوري للعناصر وكل مايحتاجه الطالب في الالمام بالمعلومات التي تفيده من خلال التعرف على المختبرات العملية والتي تخص المرحلة الثانية . ويتميز هذا الكتاب بشموله بالتجارب العملية لثلاثين تجربة والتي تخص حول مركبات عناصر في الجدول الدوري. ويعتبر هذا الكتاب كمدخل في توضيح العلاقة بين المنهج النظري والمنهج العملي بشكل مترابط المفاهيم من خلال تعرف الطالب على التجارب العملية لما لها من مجالات تطبيقية في بيئته. وإشتمل الكتاب على عشرة فصول : الفصل الأول: توجيهات مختبرية وتعليمات عامة - نموذج كتابة التقريرعن التجربة - التعرف على الأدوات والأجهزة المستخدمة في مختبر الكيمياء ، توضيح الطريقة الصحيحة للتعامل مع الأجهزة ، مبادئ السلامة الأمنية ، مخاطر المواد الكيميائية ، بطاقات التعريف ، قواعد السلامة في تخزين وتداول المواد الكيميائية ،الاشارة الى الإسستعمالات الخاطئة والصحيحة بشكل مخططات او صور او رسوم توضيحية وبعض الإسعافات الأولية . الفصل الثاني: معلومات حول الجدول الدوري للعناصر . الفصل الثالث :الهيدروجين وتجربة (1) وتخص الحوامض والقواعد والأملاح . الفصل الرابع- الفصل العاشر : التجارب من (2-30 ) تخص معلومات عن العناصر بزمر مختلفة مع ذكر المخاطر الكيميائية للمواد الكيميائية التي يتم التعامل معها في المختبر. الملاحق (Appendix ) : وتتضمن بعض الأجوبة النموذجية لبعض تجارب الكيمياء اللأعضوية الواردة في الكتاب مع أسماء جميع عناصرالجدول الدوري وبعض خواصها . الإشارات التحذيرية– إشارات المنع - الإشارات الإجبارية --الإشارات الإستدلالية .

The Effect of 3DS Max in Developing the Skill of Designing Theatrical Decoration among the Students of the Department of Art Education
...Show More Authors

The research aims at benefiting from the technological development and the technical progress. This development necessitated that the educational process take advantage of this progress, and the development of special computer software, especially the design programs, made the two researchers think about how to benefit from these design programs in teaching students the skills of theatrical design.

The current search aims at:

Identifying the effect of 3Ds Max in developing the skill of theatrical decoration design among the students of the Department of Art Education "Third stage / Department of Art Education / Faculty of Fine Arts / University of Diyala for the academic year 2014-2015.

Exposure and its working mechanisms in theatrical multi-scene model "critical dramaturgy study": يوسف رشيد جبر
...Show More Authors

The concept of intertextuality was one of the problems that occupied the attention of critics and critics in targeting the structure of textual intertextuality between texts and their overlap in the process of producing meaning. Until intertextuality became a stable term and it can be monitored in the structure of the theatrical text and determining the mechanisms of this intertextuality between texts through fields and classifications agreed upon by the most important critics who wrote and considered intertextuality. Perhaps our previous research (the approach of exposure in the epistemological hallway to intertextuality) was an attempt to interview a terminology, which the researcher intended to monitor, through the mechanisms of inter

Radiological Impact Assessment of Farm Soils and Ofada rice (Oryza sativa japonica) from Three Areas in Nigeria
...Show More Authors

Oryza sativa japonica (ofada rice) is largely grown in Aramoko, Abakaliki and Ofada are communities and consumed by both the poor and rich in Nigeria. A total of twenty ofada rice farmlands were identified in each study area and rice samples were randomly collected, thoroughly mixed to make a representative sample from each farmland. Soil samples were collected in each farm to a depth of 5-15cm from at least eight different points and thoroughly mixed together to form a representative sample. The samples were thereafter taken to the laboratory for preparation and spectroscopic analysis. A well-calibrated NaI(Tl) gamma-ray detector was used in spectrometric analysis of the samples and descriptive statistics was used to analyze th

Comparisons of Mechanical Properties of sub-mm Lead Based and Lead Free Based Solder Using in Manufacturing of Printed Circuits
...Show More Authors

Abstract

This study investigates the mechanical compression properties of tin-lead and lead-free alloy spherical balls, using more than 500 samples to identify statistical variability in the properties in each alloy. Isothermal aging was done to study and compare the aging effect on the microstructure and properties.

The results showed significant elastic and plastic anisotropy of tin phase in lead-free tin based solder and that was compared with simulation using a Crystal Plasticity Finite Element (CPEF) method that has the anisotropy of Sn installed. The results and experiments were in good agreement, indicating the range of values expected with anisotropic properties.

Deconstruction and the Acting Performance for the Shakespearean Character in the Iraqi Theatre: هيثم عبد الرزاق علي-اياد طارش ساجت
...Show More Authors

Researchers classified deconstruction as a strategy concerned with reading the philosophical, literary, artistic and critical texts according to (construction and deconstruction) binarism, which is an applied procedural space that calls for researching the layers of meaning and its non-closure. It establishes reversals in the text level.  The center changes into a margin and vice versa.  Thus the two researchers sought to study the deconstruction strategy and its work in the theatre field, that deconstruction is considered one of the most important modern currents  that actively inters in reading the theatre show.  The research studies the procedure of the construction and deconstruction of the Iraqi theatre actor reg
