This article is devoted to the study of waveguide metal-dielectric structures in frequency range 90100 GHz with low losses up 0,05 dB/m. The paper considers effect sharp irregularities on a section regular line, which leads change parameters closed path. In practice, have negative impact transfer characteristic waveguide. Therefore, types often found modern devices were investigated. As result ...

The ITS region including the 5.8S gene of rDNA of three desert truffle species were amplified using ITS4 and ITS1 primers. The ITS sequences were compared to those of other related authentic sequences obtained from GenBank. Among 12 specimens studied, seven isolates corresponded to Terfezia claveryi reported by other authors. Iranian T. claveryi specimens had an average similarity of 99.4% (ran...
