The Rock Concert Experience: The Self-Authentication Process and Wellbeing

open access: yes, 2014
The purpose of this research was to understand consumers’ experiences at rock concerts. Growth in the live concert industry over the past 20 years suggests that these experiences provide value that consumers cannot attain through other means.

Effect of Joint Inclination on Deformation and Failure of Rock Specimen with a Single Joint in Plane Strain Compression

open access: yes工程科学与技术, 2006
:Peak strength, mechanical behavior, and pattern of shear band (SB) of anisotropic jointed rock specimen were modeled by FLAC. The failure criterion of intact rock was a composite Mohr-Coulomb criterion with tension cut-off and the post-peak constitutive

Judicial Perspectives on Neurodiversity in Queensland Courts, Tribunals and Commissions: Experiences With Disclosure and Witness Credibility

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Little is known about the impacts of the disclosure, or the non‐disclosure, of medical conditions associated with neurodiversity in the context of court proceedings and hearings before tribunals and commissions. This paper examines the experiences of twenty‐three Queensland Judges, Magistrates, and Tribunal and Commission Members with ...

Multimorbidity and Associations with Cognition and Alzheimer's Disease Biomarkers

open access: yesAnnals of Neurology, EarlyView.
Objective Multimorbidity, the coexistence of 2 or more chronic conditions, has been linked to cognitive aging and Alzheimer's disease (AD) and AD‐related dementias, yet the mechanisms remain unclear. We aimed to examine the associations of multimorbidity with cognition and biomarkers across multiple mechanistic pathways.

Shear tests on rock bolts

open access: yes, 1984
Shear test have been performed in a large shear rig on Swellex bolts, massive steel bolts, massive and tube bolts of fiber glass. The inclination of the bolts to a joint plane in jointed rock, the normal stress and the type of blocks for bolt ...

To break or not to break: The role of secondary mineralisation on joint reactivation in sandstone

open access: yes
Discontinuities, including fractures and joint sets, modify the fluid transport properties and strength of rock masses. While open fractures and joints increase rock mass permeability and decrease rock mass strength, fluid flow within these structures ...

Sliding Phenomena in Intermittent Rock Joint

open access: yes, 2016
Rock bridges in rock masses would increase the bearing capacity of Non-persistent discontinuities. In this paper the effect of ratio of rock bridge surface to joint surface, rock bridge shape and number of rock bridge on failure behaviour of intermittent

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...
