اثر استخدام المختبر العلمي
...Show More Authors

أن التقدم والتطور العلمي اللذين حدثا خلال القرن العشرين كان لهما اثر كبير في المسيرة العلمية ، حيث أن من المفترض على أفراد مجتمع المتعلمين أن يتزودوا بمهارات التفكير العلمي لكي تمكنهم من العيش في العصر الحالي وليشاركوا فيه بذكاء وفاعلية حتى يحققوا لذاتهم ملائمة أفضل مع التغييرات والتطورات المختلفة التي حدثت في العالم لذا فان طرائق التدريس أصبحت حاجة ملحة لا تقل أهميتها عن المدرس والمادة الدراسية حيث أكدت جميع المؤتمرات والندوات إتباع طرائق التدريس الحديثة ورفع الكفاية التعليمية للمتعلم فكانت طريقة الاستكشاف من بين هذه الطرائق التي يكشف بواسطتها الطالب الأشياء بنفسه ويوضح المكثف الأول وليجد بنفسه سبيله إلى المعرفة . ويهدف البحث الى معرفة اثر استخدام المختبر الاستكشافي في التفكير العلمي لدى طلبة معهد الطب التقني في مادة الإحياء المهجرية من خلال التحقق من الفرضية الصفرية لا يوجد فرق ذو دلالة إحصائية بين متوسط درجات التفكير العلمي المجموعة التجريبية التي تستخدم الطريقة الاستكشافية والمجموعة الضابطة التي تستخدم المختبر التقليدي ، ثم استخدام التصميم التجريبي ذات الاختبار ألبعدي حيث تحدد البحث الحالي بطلبة معهد الطب التقني للعام الدراسي 2007- 2008 حيث اختيرت الشعبتين أ- ب عشوائياً ، اذ  بلغ عدد العينة (62) طالباً وطالبة وبواقع (32) طالب وطالبة للمجموعة التجريبية اما المجموعة الضابطة فعددها (30) طالب وطالبة وكوفئت في متغيرات ( العمر ، التحصيل الدراسي السابق لمادة الأحياء ، الذكاء ) وتم تحقيق من معامل الصعوبة والسهولة والقوة التميزية وحساب معامل الثبات باستخدام  معادلة كودرريتشاردسون  حيث بلغ عدد الثبات (87، 0 ) للفقرات الموضوعة في الاختبار ، حيث أظهرت النتائج تفوق المجموعة التجريبية التي درست مادة الإحياء المهجرية وفق الطريقة الاستكشافية على المجموعة الضابطة حيث ان استخدام الطريقة الاستكشافية تؤدي الى تنمية مهارات التفكير العلمي وتقترح الباحثة أجراء دراسة تتناول اثر استخدام المختبر الاستكشافي بمتغيرات أخرى مثل تنمية التفكير ألابتكاري وتنمية التفكير الناقد .

استخدام محاسبة التكاليف في أحتساب تكاليف المؤسسات التعليمية: دراسة تطبيقية في جامعة بغداد
...Show More Authors

The institutions of higher education and scientific research are the strategic institutions in the field of investing the human resources.

 

Expenditure on such institutions is considered a long – term investment. Thus, the financial balancing in such institutions is not a traditional one.

These institutions are not for profit organizations.

Accordingly, they need to have accounting data that are calculated on an agreed upon cost basis due to the continuous growth in the expenditure on the services rendered by these institutions. These calls for the availability of tools that help rationalize the expenditure.

Cost Accounting system is capable of providing the useful data for such purposes an

On the use of Aluminium as a plasmonic material in polarization rotators based on a hybrid plasmonic waveguide
...Show More Authors

: The Aluminium (Al) material emerged as a plasmonic material in the wavelength ranges from the ultraviolet to the visible bands in different on-chip plasmonic applications. In this paper, we demonstrate the effect of using Al on the electromagnetic (EM) field distribution of a compact hybrid plasmonic waveguide (HPW) acting as a polarization rotator. We compare the performance of Al with other familiar metals that are widely used as plasmonic materials, which are Silver (Ag) and Gold (Au). Furthermore, we study the effect of reducing the geometrical dimensions of the used materials on the EM field distributions inside the HPW and, consequently, on the efficiency of the polarization rotation. We perform the study based o

The Use of a Pulsed Nd: YAG Laser Radiation for the Removal of Intracanal Debris and Smear Layer in Extracted Human Teeth
...Show More Authors

The efficiency of Nd:YAG laser radiation in removing debris and smear layer from prepared root
canal walls was studied. Fifty-seven human extracted single rooted anterior teeth were divided into three
groups. A group that was not lased is considered as a control group. The remaining teeth were exposed to
different laser parameters regarding laser energy, repetition rate and exposure time. For the case of the set of
parameters of 7 mJ laser energy, the cleaning was maximum at 3 p.p.s. repetition rate for 3 seconds exposure
time for, the coronal, middle and apical thirds. Above and below this energy level, there was an overdose
(melting) or under dose (no effect). Nevertheless for 10mJ laser energy case, the cleaning effi

Use of chickpea soaking water in dough fermentation and its effect on quality properties of loaf bread
...Show More Authors

This study was carried out to investigate the possibility of chickpea soaked water as a substitute for yeast in dough fermentation and its effects on sensory properties of the laboratory loaf bread. Chickpea was soaked for 24,48 and 72 hours at room temperature and used in proportion with or without yeast in dough fermentation . The results revealed that , as the percentage of soaked chickpea water substitution increased, the volume of the produced loaf bread decreased as compared with the control treatment (only yeast ).Best results were obtained by using soaked chickpea water for 24 hours in proportion of 1:1 soaked chickpea water : yeast regarding the sensory properties ,volume and leavening of the loaf bread.

Reactivity of O-Drug Bond in some Suggested Voltarine Carriers: Semiempirical and ab Initio Methods
...Show More Authors

In this work, the possibility to use new suggested carriers (D= Aspirin, Ibuprofen, Paracetamol, Tramal) is discussed for diclofenac drug (voltarine) by using quantum mechanics calculations. The calculation methods (PM3) and (DFT) have been used for determination the reaction path of (O-D) bond rupture energies. Different groups of drugs as a carrier for diclofenac prodrugs (in a vacuum) have been used; at their optimized geometries. The calculations included the geometrical structure and some of the physical properties, in addition to the toxicity, biological activity, and NLO properties of the prodrugs, investigated using HF method. The calculations were done by Gaussian 09 program. The comparison was made for total energies of reactan

Useing the Hierarchical Cluster Analysis and Fuzzy Cluster Analysis Methods for Classification of Some Hospitals in Basra
...Show More Authors

In general, the importance of cluster analysis is that one can evaluate elements by clustering multiple homogeneous data; the main objective of this analysis is to collect the elements of a single, homogeneous group into different divisions, depending on many variables. This method of analysis is used to reduce data, generate hypotheses and test them, as well as predict and match models. The research aims to evaluate the fuzzy cluster analysis, which is a special case of cluster analysis, as well as to compare the two methods—classical and fuzzy cluster analysis. The research topic has been allocated to the government and private hospitals. The sampling for this research was comprised of 288 patients being treated in 10 hospitals. As t

The Use of Principal Components Analysis in the Formation of a Sustainable Human Development Index for Arab Countries
...Show More Authors

This study aims to derive a sustainable human development index for the Arab countries by using the principal components analysis, which can help in reducing the number of data in the case of multiple variables.  This can be relied upon in the interpretation and tracking sustainable human development in the Arab countries in the view of the multiplicity of sustainable human development indicators and its huge data, beside the heterogeneity of countries in a range of characteristics associated with indicators of sustainable human development such as area, population, and economic activity. The study attempted to use the available data to the selected Arab countries for the recent years. This study concluded that a single inde
