Modelling the microfiltration of lactic acid fermentation broths and comparison of operating modes [PDF]

open access: yes, 2002
clarification of fermentation broths by cross-flow microfiltration. Microfiltration experiments conducted under constant transmembrane pressure and under constant permeate fluxes (higher and lower than the critical flux) were represented by the ...

Using porous metals to enhance heat transfer in phase change materials (PCMs) [PDF]

open access: yes, 2011
Heat transfer enhancement mechanism of Phase Change Materials (PCMs) by high-porosity metal foams was investigated in this study. The Darcy-Brinkman-Forchheimer modified flow model was employed in the numerical simulations to consider the non-Darcy ...

Resistance of multilayers with long length scale interfacial roughness [PDF]

open access: yes, 2002
The resistance of multilayers with interface roughness on a length scale which is large compared to the atomic spacing is computed in several cases via the Boltzmann equation. This type of roughness is common in magnetic multilayers.

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

A comprehensive study of various regressions and deep learning approaches for the prediction of friction factor in mobile bed channels

open access: yesJournal of Hydroinformatics, 2023
A fundamental issue in the hydraulics of movable bed channels is the measurement of friction factor (λ), which represents the head loss because of hydraulic resistance. The execution of experiments in the laboratory hinders the predictability of λ over a

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Indirect Acoustic Characterisation of Membranes for the Control of Sound Absorption

open access: yesBuildings
Membranes can be used in different ways to achieve improvements in sound absorption. They can be used on top of base materials (sound-absorbing materials or other kinds) in such a way that they barely increase the thickness while increasing the sound ...

Allometric equations for estimating peak uprooting force of riparian vegetation

open access: yesFrontiers in Plant Science, 2023
Uprooting caused by flood events is a significant disturbance factor that affects the establishment, growth, and mortality of riparian vegetation. If the hydraulic drag force acting on riparian plants exceeds the peak uprooting force originate from their
