          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.

Objective: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive women.  It is affecting from 5-10% of women in reproduction age. The symptoms include infertility, hirsutism and acne, menstrual abnormalities, Obesity and may cause endometrial cancer, cardiovascular disorder and diabetes mellitus.   Leptin, the product of the ob gene, is a small peptide molecule synthesized by white adipose tissues with an important role in the regulation of fat body and food intake.

        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
