Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Fear or feast: small mammal activity increases in the presence of carcasses despite increased threat of predation by black‐backed jackals

open access: yesWildlife Biology, EarlyView.
Food acquisition is arguably the most important, and among the riskiest behaviours for most mammals. Carcasses are an ephemeral resource for many scavengers, particularly black‐backed jackals Lupulella mesomelas that prey on small mammals. Landscape of fear theory suggests that prey species should reduce their activity in areas of high predator ...

Differential Wall Rock Movements Associated With Rock Bursts, Lucky Friday Mine, Coeur d'Alene Mining District, Idaho, USA [PDF]

open access: yes
Various methods of monitoring slip movements on bedding planes, as well as examination of rock burst damage in stopes, suggests that rock bursts in the Lucky Friday Mine are closely associated with these movements.

With a Great Story Comes Great Responsibility: Role of Narrative in Leadership Development

open access: yesNew Directions for Student Leadership, Volume 2025, Issue 185, Page 81-87, Spring 2025.
ABSTRACT Comic books reside uniquely within American culture. Historians have contended comics are more than just sequential artwork mixed with engaging stories, but rather, a framework by which the generations make sense of who they are. These stories are a reflection of cultural conscience; a lens through which we can view the world and a mirror ...
