Un garrot dans l’instrumentarium du médecin antique ?

open access: yesHistoire, Médecine et Santé, 2016
The presence of a small buckle placed inside a metal box containing eye drops among the furniture of the eye specialist kit of La Favorite (Gallo-Roman Museum of Lyon) has led us to consider this insignificant object as a medical instrument in itself ...

Design Equation of Buckle Propagation Pressure for Pipe-in-Pipe Systems

open access: yesJournal of Marine Science and Engineering, 2023
This paper focuses on the buckle propagation pressure of a pipe-in-pipe system under uniform external pressure. After the validation of the finite element model used in this research, several effects were studied.

Buckling of spherical capsules [PDF]

open access: yesPhysical Review E, 2011
We investigate buckling of soft elastic capsules under negative pressure or for reduced capsule volume. Based on nonlinear shell theory and the assumption of a hyperelastic capsule membrane, shape equations for axisymmetric and initially spherical capsules are derived and solved numerically.

Improving the performance of swift-water rescue quick release harnesses [PDF]

open access: yes, 2014
This paper considered the effectiveness of empathic design modifications to quick release harness design. It was found that the critical element in effecting a rapid and efficient release was the tape length distal to the buckle/back-bar components.

CSF Levels of NPTX2 Are Associated With Less Brain Atrophy Over Time in Cognitively Unimpaired Individuals

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Neuronal pentraxin 2 (NPTX2) is a synaptic protein involved in synaptic plasticity and regulation of neuronal excitability. Lower baseline cerebrospinal fluid (CSF) NPTX2 levels have been shown to be associated with an earlier onset of mild cognitive impairment (MCI), a pre‐dementia syndrome, even after CSF Alzheimer's Disease (AD)

Unrolling of Syngonium podophyllum: Functional Anatomy, Morphology and Modelling of Its Peltate Leaves

open access: yesAdvanced Biology, EarlyView.
The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.

A rare case of scleral buckle infection with Curvularia species

open access: yesBMC Ophthalmology, 2018
Background Scleral buckling is an established modality of treating retinal detachment. Being an external implant the buckle may be prone to infections. We report such a case with a delayed presentation and a rare etiology. Case presentation A 45 year old

Buckling Bars and Boxy Bulges [PDF]

open access: yes, 1995
It has been suggested that the peanut-shaped bulges seen in some edge-on disk galaxies are produced when bars in these galaxies buckle. This paper reviews the modelling which seeks to show how bars buckle, and I present a very simple new model which ...
