Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Narrative reconstruction of the self: Living funerals as rituals of trauma and transformation

The Australian Journal of Anthropology, EarlyView.
Abstract Living funerals mark a radical reconfiguration of contemporary engagements with mortality, transforming death from an imposed ending into an actively authored narrative. This study examines the practice in Hong Kong's hybrid sociocultural landscape, where traditional Chinese death rituals collide with neoliberal selfhood and globalised ...

Time-resolved burning of solid fuels for hybrid rocket propulsion [PDF]

, 2011
Features such as lowcost, safety, throttleability, and a wide range of appealing applications (e. g., interplanetary landers, boosters for space launcher, upper stage for Vega launcher) make hybrid rocket engines a very attractive option for aerospace ...

Viability of an Electrically Driven Pump-Fed Hybrid Rocket for Small Launcher Upper Stages

Aerospace, 2019
An electrically driven pump-fed cycle for a hybrid rocket engine is proposed and compared to a simpler gas-pressurized feed system. A liquid-oxygen/paraffin-based fuel hybrid rocket engine which powers the third stage of a Vega-like launcher is ...

Leveraging Multimodal Large Language Models to Analyse Student Exploration Behaviours in Educational Game Environments

Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Video data provides rich opportunities to examine student behaviour in game‐based learning environments, capturing not only observable actions but also subtle indicators of cognitive engagement. However, traditional video analysis is labor‐intensive, and current applications of AI to this task are limited by models trained on ...

The Interplay of Teacher Agency and TPACK in AI‐Integrated Science Education: Insights From Exemplary Practice Cases

Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Teacher agency plays a pivotal role in technology‐enhanced instruction, yet empirical evidence connecting agency to the practical enactment of specific components of TPACK remains limited. In particular, the intersections between teacher agency and TPK/TCK as enacted practices warrant closer scrutiny.

Applicability of scaled testing for CAMUI-type hybrid rocket regression modelling [PDF]

, 2022
Hybrid rocket engines have several advantages over liquid or solid engines but have traditionally seen limited use due to a low thrust-to-weight ratio. The Cascading Multi-Stage Impinging jet (CAMUI) hybrid rocket engine addresses this by using a series ...
