A detector of micrometeoroids and space debris particles based on a film inductance coil
St. Petersburg Polytechnical University Journal: Physics and MathematicsIn the paper, a model of a detector of high-speed microparticles (micrometeoroids and space debris) is proposed, made in the form of a round spiral film inductance coil.

Earth, Planets and Space, 2018 We investigate a volcanic hydrothermal system using numerical simulations, focusing on change in crater temperature. Both increases and decreases in crater temperature have been observed before phreatic eruptions.

Small, EarlyView.A microstructured PVC‐based tribo‐electromagnetic nanogenerator (TEMNG) enables simultaneous harvesting of biomechanical and ambient electromagnetic energy. The hybrid device achieves high electrical outputs while supporting wearable sensing, gait monitoring, and self‐powered touch interfaces.

The scaling of secondary craters [PDF]
Secondary craters are common features around fresh planetary-scale primary impact craters throughout most of the Solar System. They derive from the ejection phase of crater formation, thus secondary scaling relations provide constraints on parameters ...

Growth and form of the mound in Gale Crater, Mars: Slope wind enhanced erosion and transport [PDF]
, 2013 Ancient sediments provide archives of climate and habitability on Mars. Gale Crater, the landing site for the Mars Science Laboratory (MSL), hosts a 5-km-high sedimentary mound (Mount Sharp/Aeolis Mons). Hypotheses for mound formation include evaporitic,

steel research international, EarlyView.Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Organic geochemistry of the Boltysh impact crater, Ukraine [PDF]
, 2009 The Boltysh crater has been know for several decades and was originally drilled in the 1960s - 1980s in a study of economic oil shale deposits. Unfortunately, the cores were not curated and have been lost.

Journal of Animal Ecology, EarlyView.Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...
