A Boost for Recycling USED Disposable Diapers

Thursday, October 7th, 2021

The future is increasingly shiny for used disposable diapers, suggests this November 5, 2020 press release from the Nippon Shokubai company of Fukuoka, Japan. It says:

“The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) [is] aiming to establish a guideline for the acceptance of used disposable diapers into the sewage system based on the New Sewerage Vision Acceleration Strategy. Recycling of used disposable diapers, the amount of which continues to increase, is thus expected to be promoted.”

Robotic Barbery on the Lawn: Hedghogs

Tuesday, October 5th, 2021

Peace has yet to be attained between robotics, lawn care specialists, and hedgehogs. This study wades into the vexatious arena:

Wildlife Conservation at a Garden Level: The Effect of Robotic Lawn Mowers on European Hedgehogs (Erinaceus europaeus),” Sophie Lund Rasmussen, Ane Elise Schrøder, Ronja Mathiesen, Jeppe Lund Nielsen, Cino Pertoldi, and David W. Macdonald, Animals, vol. 11, no. 119, 2021. (Thanks to Jesper Milan for bringing this to our attention.) The authors, at the University of Oxford, UK, and three institutions in Denmark— Aalborg University, University of Copenhagen, Fossil and Moclay Museum, Nykøbing Mors, and Agilent Technologies Denmark—report:

this study aimed to describe and quantify the effects of robotic lawn mowers on hedgehogs, and we tested 18 robotic lawn mowers in collision with dead hedgehogs. Some models caused extensive damage to the dead hedgehogs, but there were noteworthy differences in the degree of harm inflicted, with some consistently causing no damage. None of the robotic lawn mowers tested was able to detect the presence of dead, dependent juvenile hedgehogs, and no models could detect the hedgehog cadavers without physical interaction.

Tsai, Yun Mou, and Jerry C.C. Chan, Journal of Magnetic Resonance, vol. 214, no. 1. January 2012, pp. 315-8. (Thanks to Tony Tweedale for bringing this to our attention.)

Evil – the Math [new study]

Monday, September 27th, 2021

Philosophers, theologians, and many others have been searching for an unequivocal definition of Evil for at least 2,000 years. Perhaps a mathematical one might help?

Francisco Parro, who is Associate Professor of Economics, Universidad Adolfo Ibañez, School of Business, Chile, makes steps towards such things in his latest paper : The problem of evil: An economic approach [ ref: Kylos Journal (early view) ]

If the ramifications of the new approach are not immediately evident from the paper’s abstract, a full version of the study may be viewed here.
