مقدمة
تدور الدراسة في علم الاقتصاد المنزلي حول احتیاجات الانسان الضروریة لاستمرار الحیاة ومواقف في محیط
الاسرة وتفاعل مع ظروف البیئة المحیطة بھ .والتي تكون دائمة التغییر لذلك یمكن تعریف علوم وفنون الاقتصاد
المنزلي وفنونھ انھا عبارة عن مجموعة منظمة من المعارف والعلوم تتركز في محور الاسرة والمنزل حیث ینمو
ویتطور الانسان بالعلاقات الانسانیة والنواحي الاقتصادیة والاجتماعیة من جھة والنواحي العلمیة والفنیة الخاصة
بالغذاء من جھة اخرى فضلا عن النواحي العلمیة والفنیھ الخاصة بالمنسوجات والملابس التي تحتاجھا افراد الاسرة
لاتصالھا الوثیق بحیاتھم الیومیة . بحیث یعتقد البعض انھ لایوجد حقل من حقول المعرفة یعنى بحاجات الاسرة
المعاصرة وادارتھا اكثر مما یستطیع تخصص الاقتصاد المنزلي تقدیمھ . ذلك انھ یتنافس مع حقول المعرفة
المتنوعة بجانبیھا النظري والعملي من خلال تطوره المستمر ذو العلاقة بتطور مفردات حیاة الانسان.
إن تطور غایات الاقتصاد المنزلي لھ اھمیة في جعل الفرد یعیش في المجتمع عضواً نافعاً ویساعد غیره من
الافراد . كذلك یساعد على تنمیة المفاھیم والمھارات التي یحتاجھا الفرد في حاضره ومستقبلھ . ومن ھذا المنطلق
جاءت اھمیة تخصص الاقتصاد المنزلي عالمیاً حیث اصبح لھ اقسام وكلیات متكاملة في مختلف البلدان شرقاً وغرباً
. وفي الوطن العربي ھناك كلیات متخصصة في الاقتصاد المنزلي ویدرس بجدیة في مدارس البنات ضمن المواد
الدراسیة في مناھجھا ولھ ثُقلھ الخاص لاھمیتھ للفتیات في حیاتھن ، كما ان ھناك جمعیات عالمیة للاقتصاد المنزلي
في دول مختلفة ومشھورة عالمیاً بالدوریات التي تصدرھا وبمؤتمراتھا الفعالة .
ومع التطور الاجتماعي والتقدم العلمي والتكنولوجي تغیر نمط الحیاة وزادت اھمیة الجانب العلمي لمختلف
انشطة الحیاة . ولذلك تغیر مفھوم الاقتصاد المنزلي ومضمونھ للایفاء بالاحتیاجات الجدیدة للاسرة والمجتمع واصبح
تركیزه حالیاً على الجانب العلمي وجعل الاسرة محوراً للدراسة فضلاً عن المرونة وسھولة التكیف للتغییرات التي
تمس حیاة الاسرة والمجتمع .
The necessary optimality conditions with Lagrange multipliers are studied and derived for a new class that includes the system of Caputo–Katugampola fractional derivatives to the optimal control problems with considering the end time free. The formula for the integral by parts has been proven for the left Caputo–Katugampola fractional derivative that contributes to the finding and deriving the necessary optimality conditions. Also, three special cases are obtained, including the study of the necessary optimality conditions when both the final time and the final state are fixed. According to convexity assumptions prove that necessary optimality conditions are sufficient optimality conditions.

- Uncover the views and opinions of the students of Artistic Education Department about the relation between educational novelty and its relation with visual .
- Identifying the capabilities of the students of artistic education department .
The society of the research is the fourth class students of artistic education department - College of Fine Arts ( 83 students from both sexes ) . It was chosen ( 60 ) students sample of from both sexes by the researcher in order to conduct test upon them .The researcher has adopted descr

surface and underground structures. The procedure for measuring this rock strength has been
standardized by both the International Society for Rock Mechanics (ISRM) and American Society
for Testing and Materials (ASTM), Akram and Bakar(2007).
In this paper, an experimental study was performed to correlate of Point Load Index ( Is(50))
and Pulse Wave Velocity (Vp) to the Unconfined Compressive Strength (UCS) of Rocks. The effect
of several parameters was studied. Point load test, Unconfined Compressive Strength (UCS) and
Pulse Wave Velocity (Vp) were used for testing several rock samples with different diameters.

This study aims at suggesting flow as a strategy for training female EFL student-teachers in the teaching training course and finding out the effect of this strategy on their performance and their flow state. The training course syllabuses will be constructed according to the flow nine factors and the teaching skills. The measurement tools are the student-teacher performance checklist that has already been used by the department of English language and SHORT Flow State Scale (S FSS-2). The study population is represented with the (60) female student-teachers/ fourth stage/ evening studies at theEnglish department /college of education for women/the University of Baghdad. The study is used the experimental design in that (30) of the student-

Show MoreThis paper investigates the effect of magnetohydrodynamic (MHD) of an incompressible generalized burgers’ fluid including a gradient constant pressure and an exponentially accelerate plate where no slip hypothesis between the burgers’ fluid and an exponential plate is no longer valid. The constitutive relationship can establish of the fluid model process by fractional calculus, by using Laplace and Finite Fourier sine transforms. We obtain a solution for shear stress and velocity distribution. Furthermore, 3D figures are drawn to exhibit the effect of magneto hydrodynamic and different parameters for the velocity distribution.
Periodontitis is one of the most prevalent bacterial diseases affecting man with up to 90% of the global population affected. Its severe form can lead to the tooth loss in 10-15% of the population worldwide. The disease is caused by a dysbiosis of the local microbiota and one organism that contributes to this alteration in the bacterial population is Prophyromonas gingivalis. This organism possesses a range of virulence factors that appear to contribute to its growth and survival at a periodontal site amongst which is its ability to invade oral epithelial cells. Such an invasion strategy provides a means of evasion of host defence mechanisms, persistence at a site and the opportunity for dissemination to other sites in the mouth. However, p

One of the most virulence factors of this bacterium is its ability to from biofilms on solid surfaces by anchoring the planktonic cells and by producing a protective layer of extra polymeric substances. Biofilm formation is controlled through many genes. The most important ones are icaA and icaD. Dentures are prosthetic devices that are made of different materials to replace lost teeth. The aim of this study is to examine the ability of different types of denture materials to support the biofilm formation of S. aureus at phenotypic level by detecting ba
