Ferrocholesteric–ferronematic transitions induced by shear flow and magnetic field

Beilstein Journal of Nanotechnology, 2017
We study the unwinding of the ferrocholesteric helical structure induced by a combined action of a magnetic field and a shear flow. Both influences are able to induce the ferrocholesteric–ferronematic transition independently; however, the differences ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Seeding equity in African food systems: how can marginal, bottom-up initiatives promote transformations to more equitable and sustainable futures?

Ecology and Society
The multiple crises of the Anthropocene require deep transformations to achieve more sustainable, and equitable, social-ecological futures. Consequently, there is growing interest in marginal, experimental, or bottom-up initiatives that may provide ...

Transit, Transition: Excavating J641 VUJ [PDF]

Cambridge Archaeological Journal, 2009
In July 2006 archaeologists from the University of Bristol and Atkins Heritage embarked on a contemporary archaeology project with a difference. We ‘excavated’ an old (1991) Ford Transit van, used by archaeologists and later by works and maintenance teams at the Ironbridge Museum. The object: to see what can be learnt from a very particular, common and

K -> pi pi and a light scalar meson [PDF]

, 1999
We explore the Delta-I= 1/2 rule and epsilon'/epsilon in K -> pi pi transitions using a Dyson-Schwinger equation model. Exploiting the feature that QCD penguin operators direct K^0_S transitions through 0^{++} intermediate states, we find an explanation ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

A balancing act: radicality and capture in institutionalising reflexive governance for urban sustainability transitions

Urban Transformations
Over the past two decades, urban actors have sought to foster long-lasting change towards sustainability through reflexive governance. Related activities, including transition labs, arenas, experiments, and roadmaps, have been problematised for ...

Nominally forbidden transitions in the interband optical spectrum of quantum dots

, 2006
We calculate the excitonic optical absorption spectra of (In,Ga)As/GaAs self-assembled quantum dots by adopting an atomistic pseudopotential approach to the single-particle problem followed by a configuration-interaction approach to the many-body problem.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Understanding transitions using a sociocultural framework [PDF]

, 2012
Transitions have traditionally been characterised as forms of change. These may either be inner changes (new beliefs or developmental growth) or the physical move from one place to another (see Erikson, 1975), such as the move from primary to secondary ...
