This chapter investigates AI-Zahrawi's contribution to surgery especially neurosurgery. The main objective of this chapter is to study AI-Zahrawis' views on neurosurgery operation. Neurosurgery is concerned on causes of brain diseases, spine, peripheral nerves, and arteries of the neck. Abu AI-Qasim AI-Zahrawi was born in 936 C.E. in city Z

نفترض أن عولمة التخلف -بإيجابياتها الفاشلة وسلبياتها الناجحة- تفضي إلى فراغ اقتصادي وتقني في العالم العربي؛ حيث التعامل مع الفراغ لا ينتج عنه إلاَّ الفراغ. فعالم فقيرٌ اقتصاديًا وتكنولوجيًا،

يعالج هذا البحث مشكلة توظيف الأفكار في التنظير للاقتصاد الإسلامي، بهدف الاتجاه به نحو الاستقلال الفكري بخلاف تعرضه الأفكار الإنمائية السائدة والبائدة من أفكار مؤتلفة ومختلفة. ويرى البحث أن م

Vesicular drug delivery system like liposomes and niosomes, sometimes drugs are not delivered in a desired manner because of aggregation, sedimentation, stability problems and tedious method of production. By using ‘Proniosomes’ as carrier for drug delivery these problems of drug delivery can be reduced because they are easy to prepare and havi

In recent years, the atomic force microscope (AFM) has become an important tool in nanotechnology research. It was first conceived to generate 3-D images of conducting as well as nonconducting surfaces with a high degree of accuracy. Presently, it is also being used in applications that involve manipulation of material surfaces at a nanoscale. In t

In the present paper we study nonlinear dynamics of quantum quadratic operators (q.q.o.) acting on the algebra of 2 ×2 matrices M2(C). First, we describe q.q.o. with Haar state as well as quadratic operators with the Kadison–Schwarz property. By means of such a description we provide an example of q.q.o. which is not the Kadison–Schwarz operat

The present study was conducted to elucidate the relationship between the larval feeding behavior of African catfish, Clarias gariepinus and their sensory organs. We also sought to reduce the cannibalism and improve larval rearing methods for this species. The feeding behavior of intact and streptomycin-treated larvae was examined under light and d

Zaharopol proved the following result: let T, S : L1(X,F,μ) → L1(X,F,μ) be two positive contractions such that T ≤ S. If ||S−T|| < 1 then ||Sn − T n||<1 for all n ∈ N. In the present paper we generalize this result to multi-parameter contractions acting on L1. As an application of that result we prove a generalization of the “

In the present paper we first describe quantum quadratic operators (q.q.o) acting on the algebra of 2 x 2 matrices M2(C). Moreover, we provide necessary conditions for q.q.o. with Haar to satisfy Kadison-Schwarz condition. By means of such a description we give an example of q.q.o. which is not the Kadision-Schwarz operator.Quantum Bio-Informatics
