Digitalising the Age-Friendly City: Insights from Participatory Action Research

The World Health Organization’s age-friendly city initiative emerged as a response to the intersecting global trends of population ageing and urbanisation. However, a third global trend—digitalisation—has largely been overlooked in research and policy making relating to age-friendly cities and communities. Within the context of a general shift towards online civic participatory activities, this ar

Advanced laser-based techniques for gas-phase diagnostics in combustion and aerospace engineering

Gaining information of species, temperature, and velocity distributions in turbulent combustion and high-speed reactive flows is challenging, particularly for conducting measurements without influencing the experimental object itself. The use of optical and spectroscopic techniques, and in particular laser-based diagnostics, has shown outstanding abilities for performing non-intrusive in situ diag

Low-temperature statistical mechanics of the Quantizer problem : Fast quenching and equilibrium cooling of the three-dimensional Voronoi liquid

The quantizer problem is a tessellation optimization problem where point configurations are identified such that the Voronoi cells minimize the second moment of the volume distribution. While the ground state (optimal state) in 3D is almost certainly the body-centered cubic lattice, disordered and effectively hyperuniform states with energies very close to the ground state exist that result as sta

The Later Life Audio and Radio Co-operative: considering radio as a technology to promote citizen dialogue in later life

The Later Life Audio and Radio Co-operative (LLARC) is an England-widenetwork of older content creators, age-inclusive radio stations,third sector organisations, local authorities and academics workingon ageing issues. The co-operative was established in 2019 as anoutcome from a participatory action research project. Aiming topromote talk-based content created by older adults, the LLARCadvocates f

Older Voices: Supporting Community Radio Production for Civic Participation in Later Life

Community radio can support the process of having a voicein one’s community as a part of civic action, and promotecommunity dialogue. However, older adults are underrepresentedas producers of community radio shows in the UK,and face different challenges to their younger colleagues. Byworking within the radio production group of an existingorganisation of older adults, we identify the motivations a

FIB method of sectioning of III–V core-multi-shell nanowires for analysis of core/sell interfaces by high resolution TEM

The core-multishell wurtzite structure (In,Ga)As–(Ga,Al)As–(Ga,Mn)As semiconductor nanowires have been successfully grown on GaAs(111)B substrates using MBE technique. The nanowires cores were grown with gold eutectic catalyser in vapour–liquid–solid growth mode. The double shell overgrowth, on the side facets of nanowires, was performed using lower substrate temperature (about 400 ◦C, and 230 ◦C,

The modern era of light kaonic atom experiments

This review covers the modern era of experimental kaonic atom studies, encompassing 20 years of activity, defined by breakthroughs in technological developments which allowed performing a series of long-awaited precision measurements. Kaonic atoms are atomic systems where an electron is replaced by a negatively charged kaon, containing the strange quark, which interacts in the lowest orbits with t

Numerical Investigation on Thermal Performance Design of Cryogenic Compact Heat Exchangers with Serrated-Fin Channels

Traditional empirical formulas of Colburn heat transfer factors will lead to a design deviation for cryogenic heat exchangers. This paper employs the computational fluid dynamics (CFD) technique to numerically study the thermal performance of cryogenic compact heat exchangers (CCHEs). To obtain more precise convective heat transfer coefficients, the heat transfer performance of CCHE with serrated

Analysis of Fouling in Six-Start Spirally Corrugated Tubes

Fouling on heat exchanger surfaces can weaken the heat-transfer capability, increase the energy consumption, and even cause the failure of the whole system. In coaxial heat exchangers, spirally corrugated tubes perform better than smooth ones concerning heat transfer and antifouling. In this article, a parametric study on the antifouling performance of a six-start spirally corrugated tube is carri

GigaFRoST : The gigabit fast readout system for tomography

Owing to recent developments in CMOS technology, it is now possible to exploit tomographic microscopy at third-generation synchrotron facilities with unprecedented speeds. Despite this rapid technical progress, one crucial limitation for the investigation of realistic dynamic systems has remained: A generally short total acquisition time at high frame rates due to the limited internal memory of av

Making sense of circularity. An institutional logic perspective on circular business model transitions in incumbent firms.

Circular business models (CBMs) promise improved resource efficiency, value creation and retention. Still, CBM operationalization among large incumbents remains slow in practice. Yet, this plays a critical role in driving industry transformations towards sustainability. Prior research outlines challenges that incumbents encounter when operationalizing CBMs - yet remains fragmented and unable to ex

Acute Cardiovascular Effects of Hydrotreated Vegetable Oil Exhaust

Ambient air pollution is recognized as a key risk factor for cardiovascular morbidity and mortality contributing to the global disease burden. The use of renewable diesel fuels, such as hydrotreated vegetable oil (HVO), have increased in recent years and its impact on human health are not completely known. The present study investigated changes in cardiovascular tone in response to exposure to dil

3D SURFACE GENERATION FROM AERIAL THERMAL IMAGERY

Aerial thermal imagery has been recently applied to quantitative analysis of several scenes. For the mapping purpose based on aerial thermal imagery, high accuracy photogrammetric process is necessary. However, due to low geometric resolution and low contrast of thermal imaging sensors, there are some challenges in precise 3D measurement of objects. In this paper the potential of thermal video in

Implementation of the Recovery Guide in inpatient mental health services in Sweden-A process evaluation study

Background: Involving service users in inpatient care and recovery planning has gained interest worldwide. Our purpose was to evaluate the process of implementation of a coproduced Recovery Guide (RG) intervention in 22 inpatient wards in Sweden, in terms of context, implementation process and mechanisms of impact over 12 months.Methods: A mixed method design and a process evaluation framework wer

On the Prerequisites for Improving Prejudiced Ranking(s) with Individual and Post Hoc Interventions

In recruitment, promotion, admission, and other forms of wealth and power apportion, an evaluator typically ranks a set of candidates in terms of their perceived competence. If the evaluator is prejudiced, the resulting ranking will misrepresent the candidates’ actual ranking. This constitutes not only a moral and a practical problem, but also an epistemological one, which begs the question of wha

Revealing phase boundaries by weighted parametric structural refinement

Parametric Rietveld refinement from powder diffraction data has been utilized in a variety of situations to understand structural phase transitions of materials in situ. However, when analysing data from lower-resolution two-dimensional detectors or from samples with overlapping Bragg peaks, such transitions become difficult to observe. In this study, a weighted parametric method is demonstrated w

Resonant inelastic X-ray scattering of magnetic excitations under pressure

Resonant inelastic X-ray scattering (RIXS) is an extremely valuable tool for the study of elementary, including magnetic, excitations in matter. The latest developments of this technique have mostly been aimed at improving the energy resolution and performing polarization analysis of the scattered radiation, with a great impact on the interpretation and applicability of RIXS. Instead, this article
