تكمن أهمية ألبحث : تأثير تمرينات تأهيلية مصاحبة لجهاز التحفيز الكهربائي للعضلات العاملة في تخفيف الالآم أسفل الظهر للنساء بعمر (25-35) سنة والتعرف على مدى تأثير تلك التمرينات في تخفيف الألأم أسفل الظهر. وتكمن مشكلة البحث نتيجة للتقدم التكنولوجي حيث أصبحت حركة الفرد تقل شيئا فشيئا مما جعله أكثر عرضة للإصابات مما أدى الى ارتفاع نسبة عدد المصابات بالالآم أسفل الظهر وما لتلك الالام من تأثيراتها السلبية على حياتهم العملية والنفسية مما دفعت الباحثتان الى الدراسة هذا المشكلة من خلال تقوية المجاميع العضلية العاملة التي لها الدور في تخفيف الالام أسفل الظهر واختارت الباحثتان المنهج التجريبي ذو الاختبار القبلي والبعدي لملائمته لطبيعة ألبحث وتم تحديد مجتمع البحث بالطريقة العمدية إذ تكونت العينة (12) من المصابات بالألم اسفل ألظهر ووقع الاختيار على العينة المتكونة من (7) مصابات الالم اسفل الظهر وتراوحت أعمار عينة البحث ما بين (25-35) سنة وقامت بجمع أفراد العينة الذين حصلت لديهم الإصابة ضمن مدة زمنية من شهر الى ستة اشهر من تأريخ حدوث الإصابة لهم )، وتم تحديد درجة الإصابة وهي من الحالة ألمتوسطة حيث قامت الباحثتان باستبعاد (5) مصابات أخريات ممن لم يكن ضمن الشروط المناسبة للبحث واللاتي شعرن بتحسن الحالة الصحية وزوال الألم فتوقفن عن أداء الجلسات وبذلك تشكل العينة نسبة (58,333%) مـن مجموع المصابات فـي المدة الزمنية لجمعهم والـذين تـثـبت مـراجعتهم في (كلية الرافدين المركز الطبي للتأهيل الطبي والعلاج الطبيعي)،وتحققت الباحثتان من النتائج بنظام (SPSS) لتكون الاستنتاجات ان استخدام (التحفيز الكهربائي) كعامل مساعد قبل أداء التمرينات كان له الدور في زيادة التدفق الدموي بالإضافة لتسخين المنطقة مما سهل على المصابة أداء التمرينات بحرية مما يحسن من أداء العضلات بدرجة أكبر. وأوصت الباحثتان ممارسة الرياضة وتعديل السلوك اليومي من خلال الاهتمام بالأوضاع القوامية الصحيحة اثناء أداء المهام اليومية
This paper is concerned with introducing and studying the new approximation operators based on a finite family of d. g. 'swhich are the core concept in this paper. In addition, we study generalization of some Pawlak's concepts and we offer generalize the definition of accuracy measure of approximations by using a finite family of d. g. 's.
This paper proposes a new structure of the hybrid neural controller based on the identification model for nonlinear systems. The goal of this work is to employ the structure of the Modified Elman Neural Network (MENN) model into the NARMA-L2 structure instead of Multi-Layer Perceptron (MLP) model in order to construct a new hybrid neural structure that can be used as an identifier model and a nonlinear controller for the SISO linear or nonlinear systems. Weight parameters of the hybrid neural structure with its serial-parallel configuration are adapted by using the Back propagation learning algorithm. The ability of the proposed hybrid neural structure for nonlinear system has achieved a fast learning with minimum number

... Show MoreIn this paper, we present a Branch and Bound (B&B) algorithm of scheduling (n) jobs on a single machine to minimize the sum total completion time, total tardiness, total earliness, number of tardy jobs and total late work with unequal release dates. We proposed six heuristic methods for account upper bound. Also to obtain lower bound (LB) to this problem we modified a (LB) select from literature, with (Moore algorithm and Lawler's algorithm). And some dominance rules were suggested. Also, two special cases were derived. Computational experience showed the proposed (B&B) algorithm was effective in solving problems with up to (16) jobs, also the upper bounds and the lower bound were effective in restr
... Show MoreIn this paper, we generalized the principle of Banach contractive to the relative formula and then used this formula to prove that the set valued mapping has a fixed point in a complete partial metric space. We also showed that the set-valued mapping can have a fixed point in a complete partial metric space without satisfying the contraction condition. Additionally, we justified an example for our proof.
The nonhomogeneous higher order linear complex differential equation (HOLCDE) with meromorphic (or entire) functions is considered in this paper. The results are obtained by putting some conditions on the coefficients to prove that the hyper order of any nonzero solution of this equation equals the order of one of its coefficients in case the coefficients are meromorphic functions. In this case, the conditions were put are that the lower order of one of the coefficients dominates the maximum of the convergence exponent of the zeros sequence of it, the lower order of both of the other coefficients and the nonhomogeneous part and that the solution has infinite order. Whiles in case the coefficients are entire functions, any nonzero solutio
... Show More—Medical images have recently played a significant role in the diagnosis and detection of various diseases. Medical imaging can provide a means of direct visualization to observe through the human body and notice the small anatomical change and biological processes associated by different biological and physical parameters. To achieve a more accurate and reliable diagnosis, nowadays, varieties of computer aided detection (CAD) and computer-aided diagnosis (CADx) approaches have been established to help interpretation of the medical images. The CAD has become among the many major research subjects in diagnostic radiology and medical imaging. In this work we study the improvement in accuracy of detection of CAD system when comb

We also submit the relevance of fibrewise closed and open topological space on D. Also fibrewise multi-locally sliceable and fibrewise multi-locally section able multi-topological space on D. Furthermore, we propose and prove a number of statements about these ideas.
The primary objective of this paper, is to introduce eight types of topologies on a finite digraphs and state the implication between these topologies. Also we used supra open digraphs to introduce a new types for approximation rough digraphs.
