Experimental and Numerical Study on the Elimination of Severe Slugging by Riser Outlet Choking
Energies, 2022 Severe slugging is an unstable multiphase flow pattern occurs in a pipeline riser with low gas and liquid flowrates. It is highly undesired in practical operation because of the pressure and mass flow oscillations induced.

Anaesthesia, 1995 Summary Although many anaesthesia machines are equipped with circle rebreathing systems, inhalational anaesthesia remains frequently performed using relatively high fresh‐gas flows. The major advantages of rebreathing techniques can be achieved only if the fresh‐gas flow is reduced to 1 l.min ...

Estimation of Low Flow Statistics for Sustainable Water Resources Management in South Australia
Hydrology, 2022 The Magnitude and occurrence of extreme low flow events are needed in setting minimum flows to protect the instream users. As the true distribution is not normally known, the identification of the most appropriate distribution function that describes the

The level set flow of a hypersurface in $\mathbb R^4$ of low entropy does not disconnect [PDF]
, 2020 We show that if $\Sigma\subset \mathbb R^4$ is a closed, connected hypersurface with entropy $\lambda(\Sigma)\leq \lambda(\mathbb{S}^2\times \mathbb R)$, then the level set flow of $\Sigma$ never disconnects. We also obtain a sharp version of the forward

Low-Flow/Low-Gradient Aortic Stenosis [PDF]
Circulation, 2011 Aortic stenosis (AS) is 1 of the most common valve disorders encountered in clinical practice and 1 of the most frequent indications for valve replacement surgery. Decades of research and clinical experience have resulted in the development of guidelines that provide the clinician with an evidence-based approach to the management of patients with ...
