Digital radiology to improve the quality of care in countries with limited resources: a feasibility study from Angola.

PLoS ONE, 2013
ObjectiveSub-standard quality in X-ray image acquisition and interpretation is common in low-resource countries, and can ultimately result in higher patient morbidity and mortality. This study aimed at evaluating; 1) feasibility of implementing a digital

Growing wetting films: An x-ray study [PDF]

Physical Review B, 1995
The growth kinetics of thin liquid films, completely wetting a solid substrate, are studied. The film thickness is perturbed and reduced by a short thermal pulse. Subsequently the time dependence of the growth process was monitored by x-ray reflectivity measurements in the region of total external reflection.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

"The fruits of independence": Satyajit Ray, Indian nationhood and the spectre of empire [PDF]

, 2011
Challenging the longstanding consensus that Satyajit Ray's work is largely free of ideological concerns and notable only for its humanistic richness, this article shows with reference to representations of British colonialism and Indian nationhood that ...
