Nodal Analysis of Stirling Cycle Devices [PDF]

open access: yes, 1978
This paper describes a general-purpose program for the nodal analysis of Stirling-cycle devices or other cyclic regenerative machines, and presents an extensive discussion of results for an illustrative problem. The program employs finite-difference, explicit-forward solutions, and is readily adaptable to various machine topologies.

Embodied practice in a disembodied time: How the COVID‐19 pandemic shaped direct work with children and young people

open access: yesChild &Family Social Work, EarlyView.
Abstract The COVID‐19 pandemic and related restrictions imposed in the UK had a significant impact on social work practice with children and young people. As has been widely reported, practitioners were deprived of multisensory information in their assessments and of opportunities to connect with children.

Effects of leakage through clearance seals on the performance of a 10 K Stirling-cycle refrigerator [PDF]

open access: yes
The use of clearance seals is essential to achieve long life, wear free operation of Stirling cycle cryogenic refrigerators. The effect of leakage through clearance seals on the performance of such a refrigerator operating at temperatures ranging from 20

Genetic origins and climate‐induced erosion in economically important Asian walnuts

open access: yesConservation Biology, EarlyView.
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Ceramic applications in the advanced Stirling automotive engine [PDF]

open access: yes
The ideal cycle, its application to a practical machine, and the specific advantages of high efficiency, low emissions, multi-fuel capability, and low noise of the stirling engine are discussed.

Regeneration efficiency, shuttle heat loss and thermal conductivity in epoxy-composite annualr gap regenerators from 4K to 80K [PDF]

open access: yes, 1983
A test apparatus designed to simulate a section of a Stirling cycle cryocooler was built. Measurements of regeneration efficiency, shuttle heat loss and thermal conductivity reported for several regenerator test sections.

Cristiano of Arabia: Did Ronaldo increase Saudi Pro League attendances?

open access: yesContemporary Economic Policy, Volume 43, Issue 2, Page 260-270, April 2025.
Abstract In December 2022, Cristiano Ronaldo, five‐time Ballon d’Or winner and the most‐followed person on Instagram, signed for Al‐Nassr in the Kingdom of Saudi Arabia. This marked one of several expensive, recent interventions by the kingdom in global sports markets. We exploit the timing of this event to estimate superstar effects.
