Sand Liquefaction Phenomena During the Seismic Crisis of May 2012 in Emilia, Northern Italy
and boils composition Emilia Romagna earthquake
2018/6/13
In May 2012, the Emilia region of the Po Valley was struck by a seismic crisis with two major events of magnitude Mw 6.1 and Mw 5.9. The first event induced widespread sand blows formed along buried c...

The sand trap:Demand outpaces caution–and knowledge（图）
sand trap Demand outpaces caution knowledge
2017/9/20
Sand, spanning miles of beaches, carpeting vast oceans and deserts, is a visual metaphor for limitless resources. Yet researchers in this week’s journal Science seize another metaphor – sand in an ho...
That’s essentially what biophysicists at UC San Diego discovered when they began closely examining the physical properties of DNA jammed inside viruses.
“We found that under certain conditions, DNA b...
The survey and mapping of sand-boil landforms related to the Emilia 2012 earthquakes:preliminary results
Geomorphology Sand boils Digital elevation model Liquefaction Earthquake Italy
2015/8/26
Sand boils, which are also known as sand blows or sand volcanoes, are among the most common superficial effects induced by high-magnitude earthquakes. These generally occur in or close to alluvial pla...
Assessing the Importance of Sand as a Source of Fecal Indicator Bacteria (Escherichia coli and Enterococcus)
Escherichia coli Enterococcus
2015/7/21
The purpose of this activity is for students to investigate water quality, and the factors that affect it, at a local beach. This is accomplished by (1) measuring concentrations of Escherichia coli an...
Shear band in sand with spatially varying density
Bifurcation Digital Image Correlation Heterogeneous sand Shear band Strain localization
2015/7/1
Bifurcation theory is often used to investigate the inception of a shear band in a homogeneously deforming body. The theory predicts conjugate shear bands that have the same likelihood of triggering. ...
RECONSTRUCTING PAST ANTARCTIC ICE FLOW PATHS IN THE ROSS EMBAYMENT, ANTARCTICA USING SAND PETROGRAPHY, PARTICLE SIZE AND DETRITAL ZIRCON PROVENANCE
Provenance Antarctica zircons Till
2015/1/16
Tills for this study were analyzed from sites in East Antarctica (EA), West Antarctica (WA) and along a transect in the Ross Sea. Particle size, sand petrography, and detrital zircons were used to pro...
As more gardeners and farmers add ground charcoal, or biochar, to soil to both boost crop yields and counter global climate change, a new study by researchers at Rice University and Colorado College c...
SAND: An Additive for Stabilzation of Swelling Clay Soils
Clay Soils Bentonite Sand Swell Stabilization
2013/3/11
An experimental program carried out in this study seeks to understand the physical mechanisms of stabilization of an expansive soil by adding an inert material (sand) at various forms; mixing and inte...
