Synthesis, Characterization and Stability Study of V(IV), Zr(IV), Rh(III), Pd(II), Cd(II) and Hg(II) Complexes with Pyrazol Derivative
In this work lactone (1) was prepared from the reaction of p-nitro phenyl hydrazine with ethylacetoacetate
which upon treatment with benzoyl chloride afforded the lactame (2). The reaction of (2) with 2-amino phenol produced a new Schiff base (L) in good yield. Complexes of V(IV)

in addition to magnetic susceptibility and conductivity measurements. Metal to ligand [M:L] ratio was obtained for all complexes in ethanol using molar ratio method
which gave comparable results with those obtained for the solid complexes. As well as the appa

Financial markets liquidity and their impact in the return of common stocks
The research aimed to study the financial markets liquidity and returns of common stocks
Take the research the theoretical concepts associated with each of the liquidity of financial markets and returns of common stocks
As well as the use of mathematical methods in the practical side to measure market liquidity and Stocks Return
the community of research in listed companies in Iraqi stock exchange that have been trading on its stock and number 85 joint-stock company
The research was based to one premise
there is a statistically significant effect for the liquidity of the Iraqi stock exchange on returns of common stocks to traded companies in which
Using the SPSS program was to test the hypothesis research population represented Iraq Stock Exchange for a period of three years (2010-2012) on a monthly basis. The research found the set of conclusions most important rising market liquidity for Iraq Stock Exchange and followed increase in return of common stocks for a period of research
as the results of statistical analysis indicated the presence of a statistically significant effect of moral Iraq Stock Exchange liquidity on returns of common stocks
and most important recommendations should the Iraq Stock Exchange work to expand its activities in electronic trading
by providing the possibility of trading for investors through the Internet
and not limited to trading within the market
and should work to reduce the transaction costs to raise the liquidity common stock
and thus reflect positively on the liquidity of the Iraq Stock Exchange brokerage firms associated with it .
