The area of study is the southeastern part of the Mediterranean Sea. The objective of the present book is to study the hydrographic and acoustic features in front of the Egyptian coast of the Mediterranean Sea using intensive data set. Intensive hydrographic data were obtained from different sources. Hydrographic data include the temperature, salinity and depth in the study area. A computer program for exploration and graphical display of oceanographic data profile was prepared. The software runs on PCs under Windows (98/2000/NT/XP) software. The constructed program lets the user...

The concept of fuzzifying topologies appeared in 1980 under the name L-fuzzy topology, where L is a completely distributive complete lattice. It must be pointed out that Hoehle, Lowen, Sostak and Gerla were aware of the possibility to establish fuzzifying topology and in particular, Sostak and his students have done some interesting work in this field. In 1991-1993, Ying introduced the fuzzifying topology and elementally developed fuzzy topology from a new direction with semantic method of continuous valued logic.

This book deals with synthesis and biological evaluation of some new heterocyclic compounds derived from Chalcone and Curcumin derivatives. Diphenylcyclohexenone and curcumin compounds share similar functions. Both of them have, -unsaturated carbonyl structures (enone). Diphenylcyclohexenone and Curcumin were reacted with different reagents to form some new heterocyclic compounds such as Pyrazole, pyrane, pyrimidine and pyridine derivatives. These compounds have been characterized based on IR, 1H-NMR, 13C-NMR and Mass spectra. Biological activity evaluation was performed on most of...
