The effect of nanoplasmonic (Ag) on the performance of DSSCs has been studied in doped and undoped ZnO (DZ and UZ) NPs, which were prepared by the urea-assisted combustion route. Different techniques were conducted to characterize DZ and UZ NPs. XRD patterns were indexed to the hexagonal wurtzite structure of ZnO NPs (ICSD-52362). The values of average crystalline size of UZ and DZ(1.0 mol% Ag) NPs were 20.45 and 22.30 nm, respectively. HR-TEM micrograph revealed good crystallization with an intermediate or poor agglomeration with distribution of semispherical morphologies of ZnO NPs. The energy bandgap of UZ and DZ NPs was changed from 3.21 to 3.31 eV. The deconvolution of the PL spectra recognized eight peaks into near ultraviolet (NUV) and visible regions. The PL emission of visible region overshadowed NUV transition. The photovoltaic cell with the doped photoanode DZ:1.0 mol% Ag exhibited the best performance parameters:Voc = 0.46 V, Jsc = 7.81 mA.cm-2, Pm = 1.91, FF = 51%, and η= 1.91%. A double exponential function was used as a powerful fitting function for the TOCVD data.The results revealed that τn in the UZ NPs photoanode was longer than that in theDZ:1.0 mol% Ag NPs photoanode.

A simple design for a circularly polarized single-feed microstrip square patch antenna is presented. The design method consists of incorporating a narrow slot at the center of microstrip patch, producing a triangle over the slot and placing a single feed along the diagonal of the square patch. By adjusting the dimensions of the narrow slot and triangle, a circularly polarized wave can be generated. The bandwidth of the microstrip antenna can be changed by varying the angle of the triangle produced over the slot. The measured results are in good agreement with the numerical results.

needed to increase the cure rate. In vitro experiments show strong antiviral effects of fluvastatin against HCV. Aim of the study: To asses the clinical outcome of fluvastatin addition to the standard regimen for treatment of chronic HCV in Egypt. Subjects and Methods: The study included 80 patients with chronic hepatitis C virus infection fulfilled clinical, laboratory and histo-pathological criteria to be ready for interferon therapy, divided into two groups: Group I (n = 40) received standard treatment for HCV (pegylated interferon and ribavirin) and group II (n = 40) received standard treatment plus fluvastatin (80mg/daily). Before and after 6 months of treatment liver function tests and HCV-RNA were evaluated. Results: Addition of fluvastatin to the standard HCV treatment (pegylated interferon and ribavirin) significantly increased SVR from (55% to 62.5%; P< 0.01) and significantly decreased viral load in relapser patients (P< 0.001). No significant differences and correlations were found between serum levels of LDL-cholesterol and viral load before and after treatment in both groups. Conclusion: Fluvastatin can be used to increase SVR when added to standard treatment (pegylated interferon and ribavirin) of chronic HCV.
