From student to author to hospital volunteer, this N.S. teen is making waves from China
Cassidy Chisholm · CBC News · Posted: Jun 03, 2024 “Ahnaleigh Simmonds, 15, was born in Halifax, but has spent most of her life in Shanghai. The 15-year-old African Nova Scotian was born with a life-threatening condition that has since pushed her to study medicine to one day help kids like her…Her hard work even got her featured on the Wall of Love, a bulletin board that highlights volunteers inside Jiahui International Hospital. Simmonds was also featured in an online article posted by Jiahui Health…uring the pandemic, she actually co-wrote and published a book called I’m From Nova Scotia: Exploring My Black Heritage, with her grandmother, Andrea Marsman.

The Myth of No Mow May

“No Mow May” is a good start to rethinking bee health across our lawns Dal insect scientist recommends three other ways to help By Lauren Phillips, Local Journalism Initiative Reporter

I posted this comment: I have tried No Mow May, ‘found it in serious conflict with my “clover-lawn” regime, as it is good to mow (I use a manual mower) in May especially to encourage wild white clover, or to establish Dutch white clover by over-seeding. Then you have lots of clover flowers later on (as well as a natural source of nitrogen) and the clover masks weeds, making a nice blend, which indeed can include dandelion and other flowering weeds. Then when the clover starts flowering and a lot of it is pollinated, mowing stimulates more flowers… I do keep some patches of un-mowed dandelion here and there also.

A new tool in our toolbox for buckthorn control: Critical period cutting
By Laura Domyancich-Lee August 18, 2023 for fmr.prg. “In 2021, we were able to hire a contractor to scale up and refine that approach of buckthorn removal and try “critical period cutting” — an innovative technique that uses what we know about buckthorn growth to eliminate any need for herbicide use.”

The concept of the perilimnion
Ogden, James Gordon, Proceedings of the Nova Scotian Institute of Science, 36(3/4), 137-141.”Seasonal variations in surface and ground water supply and increasing attention to ionic and mass balances in aquatic eco-systems require more specific definitions of hydrologic parameters to recognize sources and sinks for biologically significant geochemistry. The term “Perilimnion” is proposed to define that zone of the catchment in which groundwater developed by surface runoff and percolation may enter (or leave) the limnic environment. The perilimnion, therefore, is an aquifer, whose geochemistry may affect, or be affected by, the waters of a lake. The term “Tardelimnion” is proposed to define that portion of the limnicenvironment in which deposition of limnogenic sediments (autochthonous or allochthonous) contribute to an aquitard, whose low coefficient of hydraulic permeability (<10-6 cm-1) virtually precludes significant hydrologic or geochemical interaction between lake and ground waters.”

Toward managing mixed-species stands: from parametrization to prescription<

Self-thinning
The principle of self-thinning is most easily described by the temporal changes that occur in the numbers of trees in undisturbed even-aged stands. However, self-thinning also occurs in uneven-aged stands. According to this principle, the finite growing space of a stand is occupied by progressively fewer trees as average tree size increases with stand age.
Trees at a competitive disadvantage die from crowding and suppression as stands approach a limiting number of trees of a given average size that can coexist within an area. As stands reach the stem exclusion stage of development (Chapter 5), tree crowns expand to fill the available growing space. Crown expansion continues until an upper limit of tree crowding is reached. Thereafter, stands follow a relatively predictable course of density-dependent tree mortality as numbers of trees per unit area decrease with increasing average tree size. It is generally assumed that the combined effects of crown expansion and tree mortality are compensatory so that canopy closure is always maintained except in the presence of ‘irregular’ mortality. The latter may be caused by such factors as air pollution, high winds, flooding, epidemic insect and disease outbreaks, and other factors.

Automata: The Extraordinary “Robots” Designed Hundreds Of Years Ago
On Youtube, under Timeline – World History Documentaries
ocumentary presented by Professor Simon Schaffer which charts the amazing and untold story of automata – extraordinary clockwork machines designed hundreds of years ago to mimic and recreate life. The film brings the past to life in vivid detail as we see how and why these masterpieces were built. Travelling around Europe, Simon uncovers the history of these machines and shows us some of the most spectacular examples, from an entire working automaton city to a small boy who can be programmed to write and even a device that can play chess. All the machines Simon visits show a level of technical sophistication and ambition that still amazes today. Thx CCF!!!!
