          Two neutron activation analysis systems were designed and studied. Americium-beryllium (Am-Be) was employed as a neutron source in both systems. Two different types of neutron sources (which differ in neutron flux) were used. One of them was used paraffin moderator  which was theoretically simulated using Monte Carlo method by GEANT4 package program of objective oriented programming.

Two cross linked polymers were synthesized, the first polymer was synthesized by condensation reaction between glycerol triethanol amine with maleic anhydride. The second polymer was synthesized by addition polymerization of free radical for acrylamide, bisacrylamide with ammonium persulphate and N,N,N,N-tetramethyldiamine (TEMED). The products were characterized by FTIR & X-ray. The resulted polymer have high rigidity and easily grinded, with high stability and used as stationary phase for HPLC.

Novel series of 14 (urea and thiourea) derivative compounds were prepared from reaction of urea and thiourea with aromatic amine compounds (homocyclic and heterocyclic), in addition to preparation of 6 Schiff bases (C=N) compounds that were prepared from reaction of some derived compounds with benzyldehyde in this study. All the 20 prepared compounds were characterized according to F.T.I.R.

        Benzylidene compounds (Schiff bases),were prepared from the reaction of 2-hydroxy benzaldehyde with different primary amines,and elucidated by infrared spectroscopy.Ferric sulfate di-hydrate salt was reacted with those Schiff bases which produced the corresponding ferric complexes.These obtained complexes were elucidated by infrared spectroscopy and metal analysis.The prepared compounds were tested for antibacterial activity.The results obtained indicated that some of these compounds were more active than the others.And the biologi
