Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Resin Transfer Molding

, 2004
The Liquid Composite Molding (LCM) refers to a number of processes that use liquid resin to impregnate the stationary fibrous pre-form. The variation of this process that is of a particular interest is Resin Transfer Molding (RTM). During the RTM Process,

Bond, tension‐stiffening, and cracking in multi‐generational recycled aggregate concrete subjected to shrinkage strains

Structural Concrete, EarlyView.
Abstract The concrete industry is responsible for a significant portion of global waste production and multi‐generation recycled aggregate concrete (MGRAC) is a means to allow the sector to transition to a circular economy framework. To predict the behavior of MGRAC at the member level there is a need to understand the underlying mechanics of bond ...

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

Wildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Discuss the Rationale for Minimally Invasive Endodontics and the Merits and Demerits of the Concept

Australian Endodontic Journal, EarlyView.
ABSTRACT Minimally invasive endodontics (MIE) places emphasis on the conservation of sound tooth structure and viable pulp tissue during endodontic procedures such as root canal treatment (RCTx) and vital pulp therapy (VPT). The use of minimal access cavity designs and conservative canal preparation dimensions have been investigated as a way to improve

The Massif Central as a Centre of Roman Brass Production? New Geochemical Data of the So‐Called Hemmoor Buckets

Archaeometry, EarlyView.
ABSTRACT New analytical data of the so‐called Hemmoor buckets, a group of brass vessels from the Roman period of the 2nd to 3rd century ad that are widespread throughout central and eastern Europe, show considerable similarities with the polymetallic Cévennes ore deposits in south‐eastern France in terms of their geochemical characteristics and lead ...

Occupational Contact Allergy to Components of Epoxy Resin Systems: Descriptive and Comparative Epidemiological Analyses Based on IVDK Data 2008–2022

Contact Dermatitis, EarlyView.
This study analyzes patch test data from 23 969 patients with occupational dermatitis to characterise sensitization to bisphenol A diglycidyl ether (DGEBA), reactive diluents, and amine hardeners. The findings show an overall decline in DGEBA sensitization with fluctuations, substantial co‐sensitization, and markedly increased risks in construction ...
