Magnetic microphase inhomogeneity as a thermodynamic precursor of ground-state phase separation in weakly coupled spin-3/2 chains

γ-CoV2O6 is a quasi-one-dimensional spin-3/2 magnet that possesses two distinct magnetic orders at low temperatures with propagation vectors k1=(½,0,0) and k2=(¼ + δh, δk, - ¼ + δl), respectively. Here we use muon spin relaxation and rotation to reveal the thermodynamics of the magnetic phase separation in this compound. In the paramagnetic (PM) region, short-range correlated spin clusters emerge

A snapshot review—Fluctuations in quantum materials: from skyrmions to superconductivity

By measuring a linear response function directly, such as the dynamic susceptibility, one can understand fundamental material properties. However, a fresh perspective can be offered by studying fluctuations. This can be related back to the dynamic susceptibility through the fluctuation–dissipation theorem, which relates the fluctuations in a system to its response, an alternate route to access the

Women as agents of change? : Reflections on Women in climate adaptation and mitigation in the Global North and South

This chapter argues that most efforts aimed at using women’s positions relative to climate change will be insufficient if not conducted with great care and analytical sensitivity. It shows that mitigation and adaptation measures of climate change often target women, either as untapped resources for combating climate change or as active and powerful participants in adaptation or mitigation efforts.

Trajectories of spatial violence in Southeast Asian cities

This paper aims to reveal how urban ‘development-induced displacement’ (Koenig, 2015; Neef and Singer, 2015) shapes and perpetuates modalities of spatial violence in the context of rapidly urbanising Southeast Asia. While Southeast Asian postcolonial scholars have explored some manifestations of spatial violence such as displacement, a comprehensive regional analysis is still lacking, especially i

Troubling partnerships: Perspectives from the receiving end of capacity development

The purpose of this paper is to complement the overwhelming focus on external partners in existing studies of capacity development for disaster risk reduction (DRR) or climate change adaptation (CCA), by exploring the perspectives of internal partners on challenges and possible solutions. 27 qualitative semi-structured interviews with experts, program officers and managers in five countries in the

Effects of leg fatigue due to exhaustive stair climbing on gait biomechanics while walking up a 10˚ incline – implications for evacuation and work safety

This biomechanics study explored stride length (SL), duration (SDN), and gait ground reaction forces (GRFspeak), required coefficient of friction (RCOFpeak), joint angle (anglepeak, anglemin), angular velocities (angvelx peak), angular accelerations (angaccx peak), muscle electromyography (EMG) during the dominant leg stance phase (SP) following an exhaustive stair ascent for evacuation. Data were

Update of clothing database for existing and new Western clothing ensembles, including effects of posture, body and air movement : Report on manikin measurements for ASHRAE 1760-TRP.

ASHRAE Research Project RP-1760 aimed to update thedatabase of western clothing as used in ANSI/ASHRAE Stan-dard 55-2013, Thermal Environmental Conditions for HumanOccupancy (ASHRAE 2013a), ISO Standard 7730-2005,Ergonomics of the Thermal Environment—Analytical Deter-mination and Interpretation of Thermal Comfort Using Calcu-lation of the PMV and PPD Indices and Local ThermalComfort Criteria (ISO

Stochastic modelling of 3D fiber structures imaged with X-ray microtomography

Many products incorporate into their design fibrous material with particular levels of permeability as a way to control the retention and flow of liquid. The production and experimental testing of these materials can be expensive and time consuming, particularly if it needs to be optimised to a desired level of absorbency. We consider a parametric virtual fiber model as a replacement for the real

Continuum scale modelling and complementary experimentation of solid oxide cells

Solid oxide cells are an exciting technology for energy conversion. Fuel cells, based on solid oxide technology, convert hydrogen or hydrogen-rich fuels into electrical energy, with potential applications in stationary power generation. Conversely, solid oxide electrolysers convert electricity into chemical energy, thereby offering the potential to store energy from transient resources, such as wi

Climate-driven losses to Indigenous and local knowledge and cultural heritage

Anthropogenic climate change is leading to widespread losses around the world. While the focus of research over the last decade has largely been on economic or tangible losses, researchers have begun to shift their focus to understanding the non-economic or intangible dimensions of loss more deeply. Loss of life, biodiversity and social cohesion are some of the losses that are beginning to be expl

A high-throughput DNA extraction method for barley seed

A non-destructive, quick DNA extraction method for barley seed is described. The method is simple and consists of drilling out a sample from the seed, adding sodium hydroxide, heating in a microwave oven and neutralizing with Tris-HCl. The seed DNA extract can be used directly for PCR with extra cycles added to the PCR programme compared to PCR programmes used for leaf extracts. This protocol was

Resolving the age of the Puchezh-Katunki impact structure (Russia) against alteration and inherited 40Ar* – No link with extinctions

The possibility of a “death from above” cause for biotic crises and extinction events is intriguing, to say the least, but such claims must be supported by reliable and reproducible data, not only impact diagnostic criteria, but also accurate and precise radioisotopic ages of the impact structures/events. To date, only one example of such an impact-related global extinction event is confirmed, at
