Hybrid Rocket Engine Ignition and Control [PDF]

, 2020
Control of a hybrid rocket engine is dependent upon a robust system capable of executing commands at precise times. In order to accomplish this, hardware systems must be in place to control the flow of a pressurized gas and provide feedback to launch ...

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

British Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...

InterPLAY: A Framework to Describe Play and STEM Engagement at Exhibits for Young Children

Curator: The Museum Journal, EarlyView.
ABSTRACT Play‐based STEM learning at exhibits is a feature of children's museums and science centers; yet little is known about how these exhibits support young children's STEM engagement. This study developed and tested the interPLAY Framework to describe play‐based STEM engagement at exhibits for young children.

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
