Using the Microsoft Excel ‘Solver’ Tool to Perform Non-Linear Curve Fitting, Using a Range of Non-Newtonian Flow Curves as Examples.

open access: yesApplied Rheology, 2001
The Microsoft Excel ‘Solver’ tool is a very simple but powerful procedure, even in the hands of the mathematically disadvantaged. It has very good application for quickly fitting experimental flow-curve data to non-Newtonian flow models with any number ...

The objective imperative: advancing chronic orofacial pain research with the brain-heart axis [PDF]

open access: yesExploration of Medicine
The biopsychosocial model is the prevailing framework for chronic orofacial pain (COP). While COP is a heterogeneous clinical entity involving nociceptive and neuropathic components, it is increasingly defined by its nociplastic features—a systemic, non ...

Challenges and opportunities in continuous flow processes for electrochemically mediated carbon capture

open access: yesiScience, 2022
Summary: Carbon capture from both stationary emitters and dilute sources is critically needed to mitigate climate change. Carbon dioxide separation methods driven by electrochemical stimuli show promise to sidestep the high-energy penalty and fossil-fuel

An examination of the use of rotational viscometers for the quality control of non-Newtonian liquid products in factories

open access: yesApplied Rheology, 2001
A frequent task undertaken by quality-control personnel in typical consumer-goods factories is the measurement of the viscosity of liquid products. The problem often faced in this task is how to strike the correct balance between the complete rheological
