The resurgence of cucurbit downy mildew has dramatically influenced production of cucurbits and disease management systems at multiple scales. Long-distance dispersal is a fundamental aspect of epidemic development that influences the timing and extent of outbreaks of cucurbit downy mildew. The dispersal potential of Pseudoperonospora cubensis appears to be limited...
The need for field and laboratory studies of the physical and
chemical behavior of environmentally significant organic molecules often
poses problems because of the toxicity of the chemical and the difficulty
of detecting it at environmentally significant concentrations.
Two dysprosium tracers, dysprosium (III) trisacetylacetonate trihydrate
and dysprosium(III) trisdibenzoylmethane monohydrate, were...
Hop (Humulus lupulus L.) production recently has expanded across the United States to
include areas of the country that have not previously grown hop commercially. In June
2015, a grower in western North Carolina detected powdery mildew in a small (<0.5-ha)
yard during routine scouting. Characteristic signs of powdery mildew...

This study explores the influence that the sustainability of hotels has on the choice of hotels. Because of recent concern about global warming and reducing energy consumption, many designers are planning sustainable buildings. But often attractiveness is sacrificed for the goal of making a building sustain in its environment. The...
Background: Chronic heavy alcohol consumption is a risk factor for bone fracture.
Using a non-human primate model of voluntary alcohol self-administration, we have recently shown that alcohol consumption suppresses intracortical bone remodeling. The current study extends this investigation to asses the effect of alcohol consumption on cancellous bone mass, architecture,...
We compare the oceanic circulation patterns over the
Southwestern Atlantic Shelf (SWAS) forced by nine
different wind stress climatologies. The largest differences
are observed in experiments forced with the Hellerman
and Rosenstein [1983, hereafter HR83] and Trenberth
et al. [1990, hereafter TR90] winds. HR83 shows a
general northeastward flow near...
Mean fields, seasonal cycles, and interannual variability are examined for fields of
satellite-derived chlorophyll pigment concentrations (CHL), sea surface height (SSH), and
sea surface temperature (SST) during 1997–2002. The analyses help to identify three
dynamic regions: an upwelling zone next to the coast, the Ensenada Front in the north,
and...
