The acidity of olive oil samples of different locations and different storage ages in yearly and weekly basis was measured. In this work, the overall results of the effect of acidity as a function of storage age in yearly basis indicate a deterioration of oil quality. The acidity results for some olive oil samples suggest that the oil can be stored...

The dielectric function of some phthalocyanine compounds (ZnPc, H2Pc, CuPc, and FePc) were investigated by analyzing the measured capacitance and loss tangent data. The real part of the dielectric constant, ε1, varies strongly with frequency and temperature. The frequency dependence was expressed as: ε1 = Aωn, where the index, n, assumes negative v...

In is work, different sized cobalt/cobalt oxide nano-rods were selectively synthesized with very narrow size distribution, using chemical preparation methods, which can be carried out by salt reduction technique. To prevent undesired agglomeration the nano-rods were stabilized.In this work two different stabilizing matrix were used: polymer and sur...

A multiperturhation theory has been developed for molecular systems. In the present paper we extend this theory to fifth order in the energy. The "bare-nucleus" hydrogenic function is chosen as the zero-order wave function rather than the more customary hartree-fock function. With this choice the multiperturbation wave functions are independent of...

This paper reports results on the electrical properties of laminated epoxy composite containing 25 layers of carbon fibers in the form of mats. The dependence of the activation energy (calculated from DC resistivity measurements) on temperature reveals two independent conduction processes. The AC impedance is independent of the applied frequency be...

Results of measurements performed on spaced layers of aluminium-epoxy composite at microwave frequencies in the X-band (8–12 GHz) are reported. These measurements were performed on pure epoxy, and on 55 and 90 wt.% composites using pairs of specimens with different spacings. These measurements include the insertion and return losses as functions of...

The dependence of some electrical properties of aluminum flake-epoxy composites on frequency and filler content is studied. The insertion loss as well as the shielding effectiveness (SE) show great dependence on filler concentration. The SE for the composites varies linearly with the microwave frequency and reaches up to 50 dB for a 90 wt.% composi...

This paper reports measurements of ferromagnetic resonance (FMR) in hematin films grown on glass substrates as a function of orientation of external magnetic field. From these measurements, it has been observed that the anisotropy for the sample without an acid is much more than that of the sample with the acid.
