The level of polymorphisms of many biochemical and DNA markers are low in
cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA
markers is limited. Molecular markers have not been developed for the most
important diseases of sunflower, such as downy mildew. The objectives of this
study were...
Nanostructured ceramics offer significant improvements in properties over the
corresponding materials with grain sizes on the order of tens to hundreds of microns.
Silicon carbide (SiC) is an important structural ceramic whose properties can
potentially be enhanced due to nanoscale microstructures. It has been suggested that
SiC samples with grain...
In recent years, there has been an increase in episodic coastal hypoxia along the mid to inner-shelf waters off the Oregon Coast. Wind-driven coastal upwelling events can exacerbate the magnitude of these hypoxic events, causing extremely hypoxic bottom water (<0.5ml l-1 dissolved oxygen) to move onshore towards the inner shelf....
Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...
A physical model study was performed to examine the forces and response of 1:6 scale wood-frame coastal residential structures subjected to storm surge and waves. An on-grade and an elevated specimen were tested and exposed to regular waves with varying water depths and wave heights to simulate Hurricane Sandy’s conditions....
Tracking vibrational motions during a photochemical or photophysical process has gained momentum, due to its sensitivity to the progression of reaction and change of environment. In this work, we implemented an advanced ultrafast vibrational technique, femtosecond-stimulated Raman spectroscopy (FSRS), to monitor the excited state structural evolution of an engineered green...
We estimate fluid sources around a subducted seamount along the northern Hikurangi subduction
margin of New Zealand, using thermomechanical numerical modelling informed by
wedge structure and porosities from multichannel seismic data. Calculated fluid sources are
input into an independent fluid-flow model to explore the key controls on overpressure generation
to...
