This paper presents a novel composite tape-spring that is suitable for use as a structural element of deployable space structures. The tape-spring uses a combination of material orthotropy and prestress to achieve the unique property known as neutral stability. A consequence of this property is that the tape-springs can be partially rolled and they neither want to unroll or rollup. Previously i...

The Geobacillus icigianus G1w1(T) strain was isolated from sludge samples of unnamed vaporing hydrothermal (97°С) outlets situated in a geyser in the Troinoy region (Valley of Geysers, Kronotsky Nature Reserve, Kamchatka, Russian Federation; 54°25'51.40″N, 160°7'41.40″E). The sequenced and annotated genome is 3,457,810 bp and encodes 3,342 genes.

This paper reports the draft genome sequence of the firmicute Geobacillus sp. strain ZGt-1, an antibacterial peptide producer isolated from the Zara hot spring in Jordan. This study is the first report on genomic data from a thermophilic bacterial strain isolated in Jordan.

The study investigates the design and fabrication of a micromachined radio frequency (RF) capacitive switch using the complementary metal oxide semiconductor-microelectromechanical system (CMOS-MEMS) technology. The structure of the micromachined switch is composed of a membrane, eight springs, four inductors, and coplanar waveguide (CPW) lines. In order to reduce the actuation voltage of the s...

A simple model for solid friction is analyzed. It is based on tangential springs representing interlocked asperities of the surfaces in contact. Each spring is given a maximal strain according to a probability distribution. At their maximal strain the springs break irreversibly. Initially all springs are assumed to have zero strain, because at static contact local elastic stresses are expected ...
