550-Year Reconstruction of Streamflow Variability in Spring Valley, Nevada

Spring Valley, Nevada, is one of several areas proposed for the pumping and export of ground-water to Las Vegas by the Southern Nevada Water Authority. Long-term annual-to-decadal variability of water supply in the region is not well understood, so tree-ring records were used to develop a longer baseline of variability in streamflow and drought episodes. Long-lived (up to about 600 years), clim...

Ordinary Differential Equations Notes for Mat 550 Spring 2013

DEFINITION 1.1. Let D ⊂ R be a domain, i.e., an open connected set. (i) A time-dependent vector field on D is a pair consisting of a domain V ⊂ D × R together with a continuous map F : V → R. (ii) The time-dependent vector field F is said to be autonomous (or one simply omits the adjective time-dependent) if V = D × R and for each x ∈ D, F (x, ·) is constant. That is to say, a vector field on D...

Association Mapping of Diastatic Power in UK Winter and Spring Barley by Exome Sequencing of Phenotypically Contrasting Variety Sets

Diastatic Power (DP) is an important quality trait for malt used in adjunct brewing and distilling. Substantial genetic variation for DP exists within UK elite barley cultivars, but breeding progress has been slow due to the limited demand, compared to the overall barley market, and difficulties in assessing DP. Estimates of DP (taken from recommended and national list trials between 1994 and 2...

Canopy Light and Tiller Mortality in Spring Barley

Mortality of tillers in barley (Hordeum vulgare L.) is an important developmental event affecting spike number and yield potential of the crop. It has traditionally been thought that increased shading of young tillers by the developing canopy initiates the premature senescence of tillers. A series of field experiments were conducted in 1982, 1983, and 1984 at St. Paul, MN on a Waukegan silt loa...
