Gassy clays containing large, discrete gas bubbles are widely spread in deposits shallow waters. The existence of may impair the original soil structure, resulting instability offshore foundations and occurrence submarine landslides. Although gassy clay was found to exhibit different undrained shear behaviors with variations initial pore water pressures volume fractions, more experimental studi...

This paper focuses on the presence of nodules insoluble materials within salt specimens, and their effect volumetric strain measurements dilatancy phenomenon. We analyzed experimental results over 120 conventional triaxial compression tests, found that in 20% cases, were atypical. also noted natural variability specimens can lead to a non-negligible data scattering when different are subjected ...

Vertical geodesy is undergoing a revolution because of two factors. First, new precise three-dimensional position measurement techniques used over very long distances and based on extraterrestrial reference systems provide a new class and precision of geometric data previously unavailable for geophysical investigations. Second, physical models in tectonic theory for large earthquakes predict cr...

Dilatancy plays a key role in mixtures of grains and fluid but is poorly investigated dry granular flows. These flows may however dilate by more than 10% column collapses. We investigate here dilatancy effects with shallow depth-averaged model designed to be further applied simulate natural landslides. use compressible μ(I), ϕeq(I) rheology law, where the volume fraction at equilibrium (i.e. cr...

this paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. for this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. the research method for...

background: dengue is a global arboviral threat to humans; causing 390 million infections per year. the availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. methods: five experimental groups (6 mice per group) each of 5-week-old balb/c mice were immunized with vaccine and placebo (empty plasmid) ...

The inelastic response of Tennessee marble is modelled by an elastic plastic constitutive relation that includes pressure dependence of yield, strain-softening and inelastic volume strain (dilatancy). Data from 12 axisymmetric compression tests at con"ning pressures from 0 to 100 MPa are used to determine the dependence of the yield function and plastic potential, which are di!erent, on the "rs...
