either alone or composite with ionic liquids up to 110 oC, choline dodecyl benzene sulfonate, ammonium dodecyl benzene sulfonate and choline chloride / urea were added in 10 wt % and 20 wt %. The conductivities of both composite polymers were improved changing the behavior of these polymers from insulator into antistatic characterization as their conductivities reach 10-9 S. cm-1.

    Pregnancy is associated with normal physiological changes that assist fetal survival as well as preparation for labour. It is typically broken into three trimesters, each of about three months. These distinctions are useful in describing the changes that take place over time. Biochemical parameters reflect these  adaptive changes are clearly distinct from the non-pregnant state. The mother and the placenta produces many hormones, maternal thyroid function during pregnancy is important for both the mother and the developing fetus.

The present work can be  divided into two parts :-

Part one : - Synthesis of six 2-(arylhydrazone) benzothiazole ligands and their Fe(III),Co(II) and Mn(II) complexes:  

     The six ligands were prepared according to the following steps:-

     Step-1- :-hydrazinolysis of 2-Mercaptobenzothiazole gave 2-hydrazino benzothiazole .
