Effect-specific analysis of propagation parameters

Results of propagation measurements with the satellite OLYMPUS carried out at 12.5, 20, and 30 GHz at the Research Center of the Deutsche Bundespost Telekom are discussed. In particular, attenuation, scintillation, and depolarization measurements are analyzed with special emphasis on frequency scaling of the various effects

To Kick Against the Pricks: An Examination of the Oresteia and the Acts of the Apostles

The major themes found in the Oresteia and the books of Luke and Acts of the Apostles are compared. By focusing on the similarities found in the themes of Justice, Religion, and New versus Old, the reader may determine if the phrase in question is being used as a literary allusion in the book of Acts of the Apostles to the Oresteia trilogy. The author believes this to be the case and believes that to arrive at a full understanding of the literary meaning of the phrase in question, an understanding of the major themes of the Oresteia is necessary

Dielectric anisotropy of nematic liquid crystals loaded with carbon nanotubes in microwave range

Liquid crystals are attractive materials for microwave applications as tunable dielectrics owing to low losses and high anisotropy of dielectric properties. The possibility of further enhancing their dielectric anisotropy is studied by loading with highly polarisable and anisotropic rods–carbon nanotubes at various concentrations. The studies are performed using two different methods, one in the range 1–4 GHz and the other at 30 GHz. More than two times increase of microwave dielectric anisotropy in liquid crystals is reported when loaded with 0.01%wt of carbon nanotubes, which is a metastable suspension and 28% increase in an equilibrated suspension. The stability of the LC-CNT composites is discussed
