Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
In Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

Generation mechanism of in-plane squeal on disk brake (Investigation of squeal generation conditions using low-degree-of-freedom analysis model)

open access: yesNihon Kikai Gakkai ronbunshu
A brake that presses a friction material against a rotating disk is called a disk brake. And it is widely used in industrial machines and automobiles. A noise called squeal may occur during braking.

Derailing Truth: Tripartite Discourse and Public Outrage Over Greece's Tempe Valley Disaster

open access: yesJournal of Contingencies and Crisis Management, Volume 33, Issue 3, September 2025.
ABSTRACT On 28 February 2023, a catastrophic rail accident near Tempe Valley in Greece claimed 57 lives and left one passenger missing, triggering widespread protests and public scepticism regarding government accountability. This study examines the Greek government's crisis response through an integrated analysis of official discourse, revealing that ...

Impact Analysis of Brake Pad Backplate Structure and Friction Lining Material on Disc-Brake Noise

open access: yesAdvances in Materials Science and Engineering, 2018
This study proposes a three-layer brake pad design, on which a six-DOF dynamic model of brake disc-brake pad is established, and the factors affecting the system instability are analyzed.

Bifurcation of the roots of the characteristic polynomial and the destabilization paradox in friction induced oscillations [PDF]

open access: yesTheoretical and Applied Mechanics, 2007
Paradoxical effect of small dissipative and gyroscopic forces on the stability of a linear non-conservative system, which manifests itself through the unpredictable at first sight behavior of the critical non-conservative load, is studied.

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

open access: yesThe Chemical Record, Volume 25, Issue 7, July 2025.
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 ...

Effect of adding mass to rotor on in-plane squeal in automotive disc brake

open access: yesMATEC Web of Conferences, 2018
This study experimentally examined disc brake-generated inplane squeal by looking at vibration modes. The in-plane squeal was determined to be closely related to both the out-of-plane squeal that has directionality caused by Coulomb friction and the in ...

Impact Analysis and Optimization of Material Parameters of Insulator on Brake Squeal

open access: yesIEEE Access, 2019
In this paper, factors that account for the disc brake noise were explored with a bench test to fix the methods of reducing the brake squeal noise. The influence of the stiffness and damping of insulator on the noise of the braking system was analyzed by

Welfare of American mink, red and Arctic foxes, raccoon dog and chinchilla kept for fur production

open access: yesEFSA Journal, Volume 23, Issue 7, July 2025.
Abstract This Scientific Opinion (SO) addresses a mandate from the EC regarding welfare of the following animals when farmed for their fur: (i) American mink (Neogale vison or Neovison vison), (ii) Red fox (Vulpes vulpes, also known as ‘silver fox’), (iii) Arctic fox (Vulpes lagopus, also known as ‘blue fox’), (iv) Raccoon dog (Nyctereutes procyonoides,
