Presentation of preload and afterload to isolated heart preparations

open access: yesThe Journal of Physiology, Volume 604, Issue 17, Page 7025-7044, 1 September 2026.
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.

Quantitative Evaluation of Frother Blend Interaction and Its Effect on Coal Flotation

open access: yes, 2013
In this investigation the weak and powerful frothers, like methyl isobutyl carbinol (MIBC) and polyethylene glycol-600 (PEG) were used for studying the surface tension of frother blends at various concentrations.

Efficient Dye Removal from Aqueous Solutions Using Rhamnolipid Biosurfactants by Foam Flotation [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2019
Methylene blue was efficiently removed from aqueous solution by foam flotation using a rhamnolipid biosurfactant as a dye collector. The effects of four parameters, namely, pH (1.5–11.5), frother concentration (5–65 ppm), aeration rate (2–6 L/min) and ...
