Seismic Evaluation of a Profile of Volcanic Ash From the South American Andes
Although soils derived from volcanic ash are only a small portion of the soils that cover the world's surface, cities have developed on some of these soils. This makes their study interesting, especially since soils derived from...

Effects of nanosilica on the calcium silicate hydrates in Portland cement–fly ash systems
Cementitious materials have a complex chemistry and naturally form nanostructures in the hydration process, a network of calcium silicate hydrates. It is considered that nanoparticles such as nanosilica could act as a pozzolanic...

Metabolic Reprogramming and Oncogenesis
The process of tumorigenesis can be described by a series of molecular features, among which alteration of cellular metabolism has recently emerged. This metabolic rewiring fulfills the energy and biosynthetic demands of fast...
A visual model for predicting chromatic banding artifacts
Quantization of images containing low texture regions, such
as sky, water or skin, can produce banding artifacts. As the bit-depth of each color channel is decreased, smooth image gradients are transformed into perceivable...

‘Public concern’, a ubiquitous notion used in descriptive and explanatory modes by policy makers, academics and the media, is often presented as axiomatic. However, the variability with which it is deployed in different...
Mental health, subjectivity and the city
Ethnography, with its focus on everyday experience, can yield significant insights into understanding migrant mental health in contexts where signs of severe mental distress remain largely imperceptible, and more generally, into...

Development and field trial of a driver assistance system to encourage eco-driving in light commercial vehicle fleets
Driver training schemes and eco-driving techniques can reduce fuel
consumption by 10% but their effectiveness depends on the willingness of drivers to change their behaviour, and changes may be short lived. On board driver...

Development of a new method to assess fuel saving using gear shift indicators
European regulations set the emissions requirements for new vehicles at 130 g CO2/km, with an additional 10 g CO2/km to be achieved by additional complementary measures, including gear shift indicators. However, there is...
