Currently, the development of satellite communications systems (SCS) is associated with the development of signals of complex structure.The popularization and distribution of software-defined radio systems (Software-defined radio, SDR) are noted, which leads to a decrease of quality of functioning of the SCS.Promising areas of countering the unauth
Abstract Leiomyosarcoma of the inferior vena cava (IVCL) is a rare retroperitoneal tumor.We report two cases of level II (middle level, renal 716 veins to hepatic veins) IVCL, who underwent en bloc resection with reconstruction of bilateral or left renal venous return using prosthetic grafts.In our cases, IVCL is documented to be occluded preoperat
Energetic composite materials (ECMs) are the basic materials of polymer binder explosives and composite solid propellants, which are mainly composed of explosive crystals and binders.During the manufacturing, storage and use of ECMs, the bonding surface is prone to micro/fine cracks or defects caused by external stimuli such as temperature, humidit
The Northern Bald Ibis Geronticus eremita is an endangered species, and recently it was reintroduced in Europe by the Waldrappteam.The reintroduction program has been strongly threatened Pull Toys by several sudden deaths, mainly in Italy.The present study used a forensic approach to analyze all of the 27 Northern Bald Ibises found dead in Italy be
Taxonomic implications of the phylogeographic studies based on multilocus sequencing of nuclear and chloroplast DNA regions of Syntrichia sarconeurum , long considered to MACHETE be Antarctic endemic moss species, are summarised.Molecular analyses confirmed the conspecificity of Syntrichia sarconeurum with S.lithophila and S.pygmaea.This taxonomic
