Effect of Resonant Mixer Granulation Parameters on Prill Properties

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Resonant mixing is a promising processing approach to manage mixing of materials with high solids content and has shown strong performance for mixing powders and pastes in energetic materials. This has led to the exploration of the approach for granulation of primary particles into millimeter‐sized agglomerates, including for generating ...

Measurements of Ionospheric Electric Fields with Antarctic Sounding Rockets S-210JA-24 and 25 (b. Electric Fields and Current System) (Proceedings of the First Symposium on Coordinated Observations of the Ionosphere and the Magnetosphere in the Polar Regions (Part I))

Antarctic Record, 1979
DC and AC (8-110 Hz) electric fields were observed in the auroral ionosphere up to 120 km with spherical double probes on board the sounding rockets S-210JA-24 and 25 at Syowa Station. The rockets passed close to auroras.

Evaluation and assimilation of Arctic Weather Satellite data in the AROME‐Arctic forecast system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The Arctic Weather Satellite (AWS), launched in August 2024, is a prototype for the future EPS–Sterna constellation of small satellites carrying an innovative microwave sounder. We present the first assessment of AWS in the regional AROME‐Arctic numerical weather prediction system, covering post‐launch calibration results and the impact of AWS ...

Measurements of Electron Number Density in the Polar Ionosphere

Antarctic Record, 1979
Under the projects of the IMS, the Japanese Antarctic Research Expedition parties carried out sounding rocket observations using the S-210JA and S-310JA rockets. The swept frequency impedance probe (NEI), which is canable of making in situ measurement of

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Gender, Social Reproduction and the Construction of Capabilities for Social Sustainability of Agriculture: A Relational Approach

Sustainable Development, EarlyView.
ABSTRACT Farmers' capabilities, a core component of social sustainability, have been largely neglected in sustainable agriculture discourse. Using a relational approach to capabilities and autonomy, this study explores how women farmers translate the opportunity of agricultural innovation into their valued outcomes, and which factors shape their ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Resource redeployment as an entry advantage in resource‐poor settings

Strategic Management Journal, EarlyView.
Abstract Research Summary Scarcity of productive factors poses a challenge for firms entering underdeveloped regions. We theorize that incumbent firms can overcome scarcity of skilled human capital in local labor markets by redeploying workers from existing units.
