How sensitive are Sahelian mesoscale convective systems to cold‐pool suppression?

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Cold pools are a ubiquitous feature of mesoscale convective systems (MCSs) with important upscale impacts on West African climate, but their role in the maintenance of tropical MCSs remains debated. Using a 40‐day model with explicit convection and no rainfall evaporation, we show that cold pools do not play a primary role in Sahel MCS development or ...

Split-Stirling-cycle displacer linear-electric drive [PDF]

open access: yes, 1983
The retrofit of a 1/4-W split-Stirling cooler with a linear driven on the displacer was achieved and its performance characterized. The objective of this work was to demonstrate that a small linear motor could be designed to meet the existing envelope ...

Characteristics of reactivity insertion accident of heat pipe reactors using different thermoelectric conversion systems

open access: yesHe jishu
Background The heat pipe reactor (HPR) is characterized by inherent safety and a compact structure, which making it widely applicable. The thermoelectric conversion system (TEC) is a key system in the HPR that converts thermal energy to electrical ...

Heat Transfer Intensification in Recuperative Heat Exchangers of the Stirling Engine

open access: yesEngineering Proceedings
The non-stationary mode of movement of the working fluid flow in the Stirling engine causes serious difficulties in the design of heat exchangers. In most cases, the operation of conventional commercial heat exchangers is considered under steady-state ...

Zeitgeist and Ortgeist: Time and Place in Institutional Creation

open access: yesBritish Journal of Management, EarlyView.
Abstract How are institutions created is one of the most interesting questions in institutional theory. Some strands of literature favour heroic explanations: mythologizing individuals with vision, tenacity and drive and putting these individuals on the pedestal of the institution.

Effects of different working gases on the heat transfer enhancement performance of a heating tube with spiral insert under oscillatory flow

open access: yesEnergy Reports, 2023
The working gas type had an important effect on the heat transfer performance of the turbulence device in the heater of Stirling engine, but the related researches were scarce, especially under the oscillatory flow.

Changing public perceptions of alcohol, alcohol harms and alcohol policies: A multi‐methods study to develop novel framing approaches

open access: yesAddiction, Volume 120, Issue 4, Page 655-668, April 2025.
Abstract Background and aims Public perceptions of alcohol and its related harms and policies are shaped by multiple discourses and can influence behaviour and policy support. As part of a FrameWorks‐informed project to test framing approaches to improve public understanding and support for evidence‐based alcohol policies in the UK, this research aimed
