    “…It has been known that Arak, Salvadora persica, has a number of medicinal properties. We tried to investigate in vitro scolicidal effect of root extracts of this plant against protoscolices from hydatid cysts of Echinococcus granulosus. …”

    “…Based on effective medium theory and dielectric resonator theory, we propose the design of reconfigurable all-dielectric metamaterial frequency selective surfaces (FSSs) using high-permittivity ceramics. The FSS is composed of ceramic resonators with different band stop responses under front and side incidences. …”

    “…The paper presents experimental studies of dielectric properties of nanofluids based on ethylene glycol and SC-TiO(2) nanoparticles with average size of 15–40 nm with various mass concentrations. The dielectric permittivity both real part and imaginary part as a function of temperature and frequency were measured. …”

    “…In order to be able to insert different peptide modules on the TP sequence to endow it with desired functions and/or eliminate unwanted regions of the protein, we have carried out a transposition screening to detect insertion-permissive points on the sequence of the TP. We report the functional characterization of 12 insertion mutants of the TP, and the identification of one site at position 38 that allows the insertion of peptides up to 17 amino acids in length while maintaining the ability of the TP to support DNA amplification in vitro. …”
