الملخص:- يهدف البحث الى معرفة اثر استراتيجية المنطقة ذات الاهمية في تحصيل مادة الكيمياء عند طالبات الصف الثاني المتوسط، ولتحقيق هدف البحث تم صياغة الفرضية الصفرية الاتية :- - لا يوجد فرق ذو دلالة احصائية عند مستوى دلالة (0.05 ) بين متوسط درجات طالبات المجموعة التجريبية اللاتي يدرسن وفقا لاستراتيجية المنطقة ذات الاهمية ومتوسط درجات طالبات المجموعة الضابطة اللاتي يدرسن وفق الطريقة الاعتيادية في تحصيل مادة الكيمياء. استعمل الباحث التصميم شبه التجريبي ذي الضبط الجزئي، وتحدد مجتمع البحث بطالبات الصف الثاني المتوسط لمدرسة ثانوية المحمودية للبنات التابعة لمديرية التربية العامة الكرخ الثانية للعام الدراسي ( 2025 – 2026 ). وبلغت عينة البحث ( 64 ) طالبة، بواقع ( 32 ) طالبة للمجموعة التجريبية درسن وفق استراتيجية المنطقة ذات الاهمية و( 32 ) طالبة للمجموعة الضابطة درسن وفق الطريقة الاعتيادية. كوفئت المجموعتان بالمتغيرات ( العمر الزمني، التحصيل الدراسي السابق لمادة العلوم، اختبار المعلومات السابقة) كما اعد الباحث مستلزمات البحث المتمثلة بـ ( تحديد المادة العلمية، صوغ الاغراض السلوكية، اعداد الخطط التدريسية). وتم بناء اداة البحث المتمثلة بناء اختبار تحصيلي تكون من ( 40 ) فقرة، اختيار من متعدد ذي اربع بدائل وتم حساب الثبات ومعامل التمييز والصعوبة وفعالية البدائل له. وبعد الانتهاء من تدريس المادة العلمية والذي استغرق الفصل الدراسي الاول للسنة الدراسية ( 2025 – 2026 ) بواقع حصة دراسية واحدة اسبوعيا لكل مجموعة وبعدها تم تطبيق الاختبار التحصيلي للمجموعتين وتم تفريغ البيانات ومعالجتها احصائيا باعتماد ( برنامج الحقيبة الاجتماعية SPSS )، واظهرت النتائج تفوق المجموعة التجريبية على المجموعة الضابطة في الاختبار التحصيلي. وفي ضوء هذه النتائج تم التوصل الى عدد من الاستنتاجات ووضع بعض التوصيات والمقترحات.
The goal of this research to identify a set of criteria that can be measured on the basis of which the effectiveness of the application of the Balanced Scorecard in the Jordanian Public Institutions in order to identify the basic requirements to ensure the application of balanced performance measures. The study population consisted of the staff of the Public Institution for Social Security - Irbid of directors of departments and heads of departments and administrative staff, was the use of a random sample of (50) an employee and the employee. The questionnaire was used as a tool to collect data, and as a result of subjecting these standards for the field test and the use of statistical analysis tools to the results of the study c

Show MoreThe research aims to prepare preventive exercises in the boot camp style to enhance the efficiency of the ankle joint and reduce its injuries for young triple jump players, and to determine the effect of preventive exercises on improving the efficiency of the ankle joint. The researchers assumed statistically significant differences between the pre-and posttests in the research variables. The experimental approach was adopted to suit it, and the research sample was chosen from young triple jump players. The preventive approach prepared by the researchers was applied to the sample, and it included preventive exercises in the boot camp style with and without tools. The researchers concluded that preventive exercises in a boot camp style have

Show MoreThis study is an investigation of the drugs effect on some pathogenic Acanthamoeba isolated from Iraqi waters, where the problem of environmental adaptation that characterizes this organism in addition to being a reservoir for many pathogenic microorganisms that take shelter in it to escape disinfectants and medicines is sometimes difficult to treat it with traditional treatments. Twenty water samples were collected from different water regions in Iraq, namely the Dokan Lake, Tigris River, Euphrates River and Najaf Sea, 5 samples from each source. Acanthamoeba was isolated from water samples on NNA and PYG media, using an inverted microscope with an electron microscope to determine their phenotypic features. PCR and

Show MoreA factorial experiment was applied with four replicates on rosemary plants (Rosmarinus officinalis L.) grown in pots inside the glasshouse of the Department of Biology, College of Science, Salahaddin University, Erbil, Iraq, during April, 2019 to July, 2020, to determine the effects of soil moisture content ( SM1: 100% and SM2: 60% field capacity), nitrogen fertilizer (N1: 100, N2: 200 and N3: 300kg/hectare), and magnesium fertilizer (Mg1: 0.0, Mg2: 30 and Mg3: 60kg/hectare) and their interactions on some growth characteristics and essential oil content of rosemary plants. Two cuttings were taken from rosemary shoots (on March, 2020 and July, 2020) after 12 and 15 months of planting respectively. Results showed that cutting 1:

Show MoreLaboratory studies were conducted at the biological control unit, college of Agriculture, University of Baghdad to evaluate some biological aspects of the predator Chilocorus bipustulatus (Coleoptera: Coccinellidae), which is considered one of the most important predators on many insect pests, especially the scale insect, Parlatoria blanchardi, (Homoptera: Diaspididae) on date palms. The results showed that biological parameters of the predator were varied according to different degree of temperature. Egg incubation period was significantly different and reached to 7.5 and 5.44 day at 25 and 30°C respectively, Fertility was the same 100% at both temperature degrees. Larval growth periods were 17.41 and 16.12 day as well as the mortality

Using alkaline extracts of 8%, the study has been shown clear effect increased in mortality rate for fourth larval stage 93.3% and degressed to 66.6% at 4% concentrate to 13.3% with control treatment .Ahigher percentage of pupal mortality 16.6% at 4% concentrate has been observed, while no natural emergence carried out at concentrates of 4.6% comparing with control treatment of 86.66%, at the same time percentage of deformation has been increased to 16.66% at 4% of extracts and degressed to 6.66% at 6% while no deformation have been shown with control treatment .

Show MoreThe current study aimed to investigate the viability of biofilm formation klebsilla pneumoniae and Staphylococcus aureus. 440 urine samples were collected from patients suffering from urinary tract infection (UTI) from those who were admitted and visitors to Al-Ramadi Teaching Hospital, Al-Yarmouk Teaching Hospital, Al-Ramadi Teaching Hospital for women and children and , Teaching Laboratories in the Medical City for both genders for a period extended from 5 July, 2017 to 10 October, 2017. Samples were diagnosed by culturing them on a selective media and by biochemical testes , also, diagnosis was ensured by using VITEK-2 compact system. Results showed that K.pneumoniae isolation ratio was 17.1%(68) and S.aureus ratio was 13.1%(52). Thei

This process has led to the urbanization of rural areas, and to have overlapping edges and margins of areas, which were outside the basic design of the city. Accordingly, the present research assumes that the accelerating growth of Baghdad population has contributed significantly to the process of unplanned urbanization. Thus, the study aims to examine the factors that have led to an increase of urban sprawl at the expense of the agricultural land. The study has thus adopted the descriptive, analytical, and historical approaches relying on the simple linear regression method to predict the phenomenon of urban expansion and its
