The Action of Sunlight [PDF]

open access: yesNature, 1921
REFERRING to Dr. Saleeby's letter in NATURE of December 8, p. 466, I may report that, in conjunction with the late Marshall Ward, professor of botany at Cooper's Hill, I carried out a number of experiments at Liverpool near the end of last century on the effect of light in slaughtering anthrax bacilli.

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 ...

A Brief History of the Yield Stress

open access: yesApplied Rheology, 1999
This short article is a summary of a recently published, lengthy review [1] in which the author challenges the often-accepted view that materials have yield stresses, below which no flow takes place.

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

On-line or Process Viscometry – A Review

open access: yesApplied Rheology, 1999
Process viscometry has many advantages in terms of saving time and gaining more immediate information about a process. However, it can also has disadvantages in terms of compromises that must be made in taking a stream of liquid and passing it through a ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
