Planning for Observations of the Plasma Waves by Sounding Rockets in Antarctica

Antarctic Record, 1975
The plasma wave observations in the polar ionosphere consist of two categories; the first is for the emission due to the particle precipitation and the second is for the emissions that are thought to be generated in the magnetosphere as a result of the ...

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Stability of Medicinal Nanoemulsions to Spaceflight: Insights From the StarMed Experiment. [PDF]

Adv Healthc Mater
Chitosan‐coated melatonin nanoemulsions (MN) recovered from a sounding rocket mission preserve droplet size and controlled‐release behavior, whereas uncoated nanoemulsions show ageing‐driven droplet growth and increased accessible drug fraction. Simple polymer coatings thus enhance the flight resilience of liquid space medicines under cumulative launch

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Proposal of architecture for launcher systems of unguided sounding rockets

, 2006
This work presents a proposal of systemic architecture, to make automatic actions in the positioning of launch rail of unguided sounding rockets, which are based on a supervision system, a programmable logical controller, a sensory and actuators ...

F-Region electron density irregularities during the development of equatorial plasma bubbles [PDF]

Geofísica Internacional, 2000
The height variation of the ionospheric electron density was measured with rocket-borne electron density probes in two campaigns conducted from Alcantara (2.31°S; 35.2°W), Brazil. A Black Brant X sounding rocket was launched on 14 October 1994 at 1955hrs

When Time Stands Still: The Destructive Experience of Ambiguous Loss among Mothers of Combat Soldiers

Symbolic Interaction, EarlyView.
What happens when stories refuse coherence? This article examines ambiguous loss among mothers of combat soldiers, focusing on how prolonged waiting and uncertainty infiltrate everyday life, eroding sensemaking. Drawing on ethnographic interviews, it explores how mothers experience the contraction of time and space—manifested in suspended routines ...

Supporting Young Foreign Language Learners With Image Generative AI in Digital Multimodal Composing: Benefits and Challenges

TESOL Quarterly, EarlyView.
Abstract Integrating generative artificial intelligence (GenAI) into digital multimodal composing (DMC) offers promising avenues for young Foreign Language (FL) learners' learning experiences. Image‐based GenAI tools enable students to generate personalized images from written prompts to help convey meanings, and DMC combines text, images, and sound to
