In research we prepared electrical conductive polymer mixture wich consisted of three polymers [pectin, poly vinyl acetate and poly Aniline] was prepared then doping silver nanoparticles. Meaning it was conducting research on the three stages the first is Preparing triple polymer blend , Preparing silver nanoparticles and Tchoub mix triple Article nanoparticles in different proportions to get (Nanopolymer composites), and Preparing and making chips complexes in (casting method) for the purpose of measuring electrical conductivity her. Also we examined samples spectrum infrared (FT-IR), X-ray diffraction), SEM microscope and atomic force microscopy AFM. Electrical conductivity of the device chips have been measured (LCR) results showed that the electrical conductivity values of chip made from polymer mix are triangular (0.514 s/m) either the connectivity nanopolymer composite Increased to (1.66 s/m).

A Genetic Algorithm optimization model is used in this study to find the optimum flow values of the Tigris river branches near Ammara city, which their water is to be used for central marshes restoration after mixing in Maissan River. These tributaries are Al-Areed, AlBittera and Al-Majar Al-Kabeer Rivers. The aim of this model is to enhance the water quality in Maissan River, hence provide acceptable water quality for marsh restoration. The model is applied for different water quality change scenarios ,i.e. , 10%,20% increase in EC,TDS and BOD. The model output are the optimum flow values for the three rivers while, the input data are monthly flows(1994-2011),monthly water requirements and water quality parameters (EC, TDS, BOD, DO and

Fabrication and investigation of the properties of CdSe/ZnS core/shell for the luminescent solar concentrates (LSC) application is presented. An increase of the efficiency of a silicon solar cell was obtained by applying the LSC. The increase was a result of the optical properties of the semiconductor nanoparticles CdSe/ZnS core/shell that were deposited over the top surface of the silicon solar cell facing the illumination source (Halogen lamp). The gravity force was invested for the film deposition process.The optical properties of these nanoparticles were studied. The absorption spectra for the CdSe/ZnS core-shell were 270-600nm, i.e., located within the spectral response area of the examined solar cell. The energy gap values for CdSe
