ND-Ol, A High Oleic Acid Sunflower Synthetic
This is a discussion of the oils that french cut potatoes may be fried in. Some oils are synthetic. The article gives background into sunflower oil. Sunflower oil is less saturated, has an increased oleic acid content, is less susceptible to oxidation during processing, storage and frying. Possible industrial usages are mentioned in the article. The agronomic and quality characteristics of ND-01 synthetic sunflower oil are given along with it's growing contexts
Contemporary and paleo-rockfalls as proxies for strong ground motions
A major hazard accompanying earthquake shaking in areas of steep topography is the detachment of
rocks from bedrock outcrops that subsequently slide, roll, or bounce downslope (i.e. rockfalls). The
2010-2011 Canterbury earthquake sequence caused recurrent and severe rockfall in parts of southern
Christchurch. Coseismic rockfall caused five fatalities and significant infrastructural damage during
the 2011 Mw 6.2 Christchurch earthquake. Here we examine a rockfall site in southern Christchurch
in detail using geomorphic mapping, lidar analysis, geochronology (cosmogenic 3He dating,
radiocarbon dating, optically stimulated luminescence (OSL) from quartz, infrared stimulated
luminescence from K-feldspar), numerical modeling of rockfall boulder trajectories, and ground
motion prediction equations (GMPEs). Rocks fell from the source cliff only in earthquakes with
interpolated peak ground velocities exceeding ~10 cm/s; hundreds of smaller earthquakes did not
produce rockfall. On the basis of empirical observations, GMPEs and age chronologies we attribute
paleo-rockfalls to strong shaking in prehistoric earthquakes. We conclude that earthquake shaking of
comparable intensity to the strongest contemporary earthquakes in Christchurch last occurred at this
site approximately 5000 to 7000 years ago, and that in some settings, rockfall deposits provide useful
proxies for past strong ground motions
