Analytical study of S-wave propagation across saturated joints in rock masses

Joints are important mechanical and hydrological features of rock masses, and they can greatly affect wave propagation and attenuation across jointed rock masses.

2022 Resource Operators Conference (ROC2022)

, 2022
Rock joints govern an important role in the overall stability of rock slope which may be filled with infill material due to transported materials with water, weathering as well as joint shearing. There are two methods of testing rock joint shear behavior,

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms

American Journal of Agricultural Economics, EarlyView.
Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

Upcycling Water Pollutants Into Long‐Chain Polymers via Synergistic Interfacial Dechlorination and Organic Radical Stabilization

Angewandte Chemie, EarlyView.
HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.

Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Mesoporous N,S‐Dual‐Doped Carbon Nanoreactors via Entropy‐Driven Interface Self‐Assembly for Efficient H2O2 Electrosynthesis

Angewandte Chemie, EarlyView.
An entropy‐driven interface self‐assembly strategy is proposed for the controllable synthesis of mesoporous N,S‐dual‐doped carbon nanoreactors. The N,S‐dual‐doping sites optimized the *OOH adsorption, boosting the 2e− selectivity, while the favorable mesostructure accelerated O2 enrichment.

NO NĀ PUA: Exploring the feasibility of culture‐based social prescribing on firefighters' wellbeing in Hawaiʻi

American Journal of Community Psychology, EarlyView.
Abstract Firefighters face an array of stressors due to the demands of their occupation, leading to a high prevalence of mental health challenges. Social prescribing represents a novel approach to healthcare that emphasizes a holistic view of health and wellbeing.

“It's Not Deterministic and It Will Never Be Deterministic”: A Qualitative Study on Stakeholder Perspectives of Polygenic Risk Score Testing for Post‐Traumatic Stress Disorder

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Post‐traumatic stress disorder (PTSD) causes significant mental and physical distress, yet only a small subset of individuals exposed to trauma develop the disorder. Scientists and clinicians are still unable to predict who will get the disorder or how it will manifest.

Development of surface replacement prostheses for the proximal interphalangeal and metacarpo phalangeal joints [PDF]

, 1997
There were two main aims of the project. A surface replacement prosthesis was previously designed at the University of Durham for the metacarpo-phalangeal joint (MCPJ).
