Investigation by laser doppler velocimetry of the effects of liquid flow rates and feed positions on the flow patterns induced in a stirred tank by an axial-flow impeller [PDF]
, 2002 The (ow patterns established in a continuously-fed stirred tank, equipped with a Mixel TT axial-(ow impeller, have been investigated bylaser Doppler velocimetry, for a high and a low value of mean residence time—mixing time ratio.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats
The Anatomical Record, EarlyView.Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Dataset of Quiet Space Weather Periods for Ionospheric Studies
Earth and Space ScienceThe ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal.

Processing of CW Doppler images to extract velocity profile [PDF]
, 2012 The present work aims to find a good way to automatically trace the velocity profile in vessels shown in continuous wave Doppler spectrograms, replacing the more traditional manual tracing, easy to perform but rich in drawbacks.

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation
The Anatomical Record, EarlyView.Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Atmospheric Re-Entry Analysis of Sounding Rocket Payloads [PDF]
, 2007 The atmospheric re-entry of sounding rocket payloads is an important phase of the ballistic flight, especially when instruments and experiments shall be recovered for future flights or interpretation of experiment data.

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review
Clinical Anatomy, EarlyView.ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Ejection and recovery system for CubeSat sized ejectables on sounding rockets [PDF]
, 2013 Many sounding rocket experiments have the requirement to be free flying due to their size or the required precision of their measurements which would be falsified by other experiments on-board the same sounding rocket.
