In this paper, design and simulation of a deployment and release mechanism of a communication satellite antenna are described.Because of the simplicity and reliability of the system, a torsion spring is used to excite the antenna.Dynamic simulation is performed by Adams Software and the appropriate spring and damper are selected for the mechanism.A
The response of Monterey Bay to the Great Tohoku earthquake of 2011 is examined in this study.From a practical standpoint, although the resulting tsunami did not cause any damage to the open harbors at Monterey and Moss Landing, it caused extensive damage to boats and infrastructure in Santa Cruz Harbor, which is closed to surrounding waters.From a
IntroductionThe late autumn epizootic of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in Serbia in 2023 caused massive mortality in the migratory population of common cranes (Grus Grus).This is the first time HPAIV has been identified in the common crane in Serbia, leading to mass mortality of this bird species.MethodsTo underst
It is generally acknowledged that using germanium Kitchen Supplies as a wetting film for silver nanolayers decreases the surface roughness of the metal.However, germanium atoms also tend to segregate towards the surface of silver films, increasing ohmic losses in the structure.Here we propose an Au/Ge/Ag based structure where the segregation of ger
