The Gold‐Maker of Animal Oil and Prussian Blue Fame — The Chemical and Medicinal Science Philosophy of Johann Conrad Dippel

The Chemical Record, EarlyView.
The radical Pietist Johann Conrad Dippel was a self‐proclaimed adept – a maker of gold and the philosophers’ stone. He was also a magister of theology, a doctor of medicine, and a self‐taught chemist, who coinvented the pigment Prussian Blue together with Johann von Diesbach, became known for his animal pyrolysis oil, his wonder‐wound balm, his ...

Semi‐tilling maintains the arthropod food web structure but decreases biological pest control in olive groves

Annals of Applied Biology, EarlyView.
Semi‐tillage, a widely used agricultural method to improve water availability and minimise soil erosion in crops, may compromise pest control in olive groves. Stable isotopes (N15 and C13) analysis showed an effect of semi‐tillage in the composition of the basal resources of potential natural enemies in the three olive grove strata: These changes may ...

Stationary Soap Film Bridge Subjected to an Electrostatic Force: The Balanced Case [PDF]

arXiv
We analytically study a stationary free boundary problem describing a soap film bridge subjected to an electrostatic force. Starting from a cylinder that the soap film forms if its surface tension and the electrostatic force are perfectly balanced, we construct a local branch of stationary solutions. Then, we prove that there is a sharp threshold value

Guanidine based vehicle/binders for use with oxides, metals and ceramics [PDF]

, 1995
The use of guanidine salts of organic fatty acids (guanidine soaps) as vehicles and binders for coating substrate surfaces is disclosed. Being completely organic, the guanidine soaps can be burned off leaving no undesirable residue.

Ecological factors underlying the spatiotemporal dynamics in a key forest beetle pollinator Facteurs écologiques à la base de la dynamique spatio‐temporelle d'un important coléoptère forestier pollinisateur

Agricultural and Forest Entomology, EarlyView.
Eusphalerum, an understudied beetle pollinator in North America, comprises over 50% of beetle specimens collected using flight‐intercept traps in forests across New Brunswick, Canada. In a study investigating its phenology, congeneric aggregation and population dynamics, we demonstrated that Eusphalerum exhibits unique phenology distinct from other ...
