High Voltage, EarlyView.ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

High Voltage, EarlyView.ABSTRACT The complex diffusion of characteristic gases within oil‐immersed transformers significantly influences the timeliness between the fault occurrence and gas detection. So far, the gas transport processes and spatio‐temporal distributions remain inadequately understood.

Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT This study investigates the effects of male and female empowerment, as well as gender empowerment inequality, on the adoption of climate‐smart agriculture (CSA) practices. Using a conditional mixed process model, we analyse survey data from 743 households across Henan, Shandong and Hebei provinces in China.

British Journal of Management, EarlyView.Abstract As global commitment to the United Nations Sustainable Development Goals (SDGs) intensifies, firms are increasingly expected to contribute actively towards achieving these goals. Drawing from the relational view, this study investigates how firms’ alliance management capability enhances SDG performance, specifically through business model ...

The Milbank Quarterly, EarlyView.Policy Points Position Universal, High‐Quality Education as a Foundational Public Health Strategy. Long‐term health and life expectancy in the United States are shaped more by educational attainment than by any other single factor. Disparities in access to early childhood, K‐12, and higher education perpetuate cycles of chronic disease, economic ...

Uncovering Biogas Outcomes: Tales of Hubris, Hope, and Failure From Southern Malawi
Natural Resources Forum, EarlyView.ABSTRACT The purpose of this article is to speak directly to biogas failure. Over the past two decades, immense amounts of money have been spent by African governments, private individuals, and most conspicuously, international aid agencies and donors, on countless biogas projects in every country on the continent.

WAH‐i: Optimising microphone array geometry for customised localisation accuracy
Methods in Ecology and Evolution, EarlyView.Abstract Accurate spatial localisation of free‐flying echolocating bats is foundational for resolving fine‐scale flight and echolocation behaviour, prey interception and spatial decision‐making in natural environments. Acoustic localisation using microphone arrays is widely employed for this purpose, yet array geometries in field studies are typically ...

Fuel Stagnation Temperature Effects on Mixing with Supersonic Combustion Flows
Journal of Propulsion and Power, 1997 An experimental study of the effect of fuel stagnation temperature on mixing in a supersonic hydrogen-air flame is described, The combustor consisted of a constant-area rectangular duct with a centrally located fuel-injection strut that spanned the width. A high-enthalpy stream of air was supplied by a free-piston shock tunnel, and heated hydrogen fuel,

Emittance from stagnation temperature study
Solar Energy, 1984 Variation of stagnation temperature of various coatings kept in an insulated one glass cover box is theoreticall analysed. This shows that it is possible to make an approximate estimate of thermal emittance of the coating of known absorptance from the knowledge of stagnation temperature, ambient temperature and solar insolation.

A representation for the temperature field near the stagnation region in oblique stagnation flow
Physics of Fluids A, Fluid Dynamics, 1990Oblique stagnation flow has been the subject of previous work. In this Brief Communication, attention is restricted to the case in which the flow is steady, inviscid, and two dimensional. A general solution to the thermal field valid in the region of the stagnation point, which formally exhibits x dependence, is sought.
