يعد تحليل السلاسل الزمنية من المواضـيع الهامة في تفسير الظـواهر التي تحدث خلال فترة زمنية معينة. ان الهدف من هذا لتحليل هو الحصـول على وصف وبنـاء أنموذج مناسب من اجل اعطاء صورة مستقبلية واضحة للسلاسل الزمنية المدروسة وان السلاسل الزمنية اهم الادوات المستخدمة في بناء وتقدير والتنبؤ بالظواهر المختلفة وان الاستدامة المالية هي الحالة التي تكون فيها الدولة قادرة على الوفاء بالتزاماتها الحالية والمستقبلية من غير تغيير سياساتها اذ تعتبر من اهم المشاكل التي تواجه الصندوق لارتفاع اعداد الخارجين من الخدمة وارتفاع اعداد المتقاعدين مما يتسبب في ارتفاع حجم انفاق صندوق التقاعد والضمان الاجتماعي ولاعتماد الصندوق على ايرادات الاشتراكات التي يعتمد عليها بشكل شبه تام في تمويل الصندوق اذ استخدمت خصائص السلاسل الزمنية واختبار التكامل المشترك وانموذج متجه تصحيح الخطأ Vector Error Correction Model ومن ثم المقارنة من خلال المعايير,Sum Square Error Root Mean Square Error لإيجاد افضل انموذج من نماذج التمهيد الاسي للتنبؤ بالقيم المستقبلية، اذ تم التوصل الى ان السلاسل الزمنية (الانفاق والايراد) ساكنة بعد اخذ الفرق الاول وفق Augmented Dickey Fuller وتوصل البحث الى ان فترة الابطاء المثلى هي الفترة الثالثة بالاعتماد على معيار Akaike Information Criterion واشار اختبار Johansen – Juselius الى وجود علاقة توازنية طويلة الاجل بين المتغيرات وان هناك علاقة متجه من الايراد الى الانفاق وفق Vector Error Correction Model لان معلمة تصحيح حد الخطأ سالبة ومعنوية وان انموذج متجه تصحيح الخطأ بين نفقات وايرادات الصندوق خالي من مشكلة الارتباط المتسلسل وخالي من مشكلة عدم تجانس التباين وان افضل انموذج للتنبؤ للمتغيرات البحث هو التمهيد الاسي لمعلمتي هولت لأنه اعطى نتائج دقيقة وقريبة من القيم الحقيقية.
The current study was conducted for studying the impact of cold plasma on the expression level of three genes that participate in the biosynthesis of the phenylpropanoid pathway in Ocimum basilicum. These studied genes were cinnamate 4-hydroxylase (c4h), 4-coumarate CoA ligase (4cl), and eugenol O-methyl transferase (eomt). Also, the cold plasma impact was studied on the essential oil components and their relation with the gene expression level. The results demonstrated that cold plasma seeds germination of the treated groups 2 (initially for 3 minutes and 3 minutes after 7 days) ,and group 3(initially for 5 minutes and 3 minutes after 7 days) were faster than the control group. Also, the height average of the mature plants of

Diazotized metoclopramide reagent react with bisphenol F produces an orange azo-compound with a maximum absorbance at 461 nm in alkaline solution. The experimental parameters were optimized such as type of alkaline medium, concentration of NaOH, diazotized metoclopramide amount, order additions, reaction time, temperature, and effect of organic solvents to achieve the optimal performance for the proposed method. The absorbance increased linearly with increasing bisphenol F concentration in the range of 0.5-10 μg mL-1 under ideal conditions, with a correlati

Show MoreThe increasing rates of consumption of cigarettes harmful, to health in the world in general, and in Iraq in particular, and because of the costs borne by individuals, and the state as a result of addressing its damage, as well as Iraq's commitment, to international conventions against cigarettes, and demands of the World Health Organization, to raise prices to reduce consumption. Therefore, the tax Selectivity is one of the most important ways of regulating the consumption of this commodity on the one hand and increasing the tax revenue on the other. The research aims to shed light on the issue of selective tax on cigarettes and the impact of their application in increasing tax revenues and identify the effectiveness of the application

Negatively "on the measurement and accounting disclosure of financial reports prepared by oil companies, and the research aims to lay down sound procedures for measuring and classifying oil costs and additional costs paid to foreign companies, and recognizing and recording them in th

The recent trends in evaluation and educational reform movements have called for using alternative evaluation, which focuses on performance evaluation. Authentic assessment is usually described as formative, in which students participate in their acquisition, in addition to the fact that students are productive and active, which is reflected in the students' achievement and skill level. The study aims to reveal the degree of knowledge and use of alternative assessment tools by primary school teachers in Gaza -Palestine. To meet the objective of the study, the researchers used the descriptive-analytical method and the questioner as a study tool. The study sample c
