Deoxynivalenol (DON) is a secondary metabolite of Fusarium culmorum and Fusarium graminearum and is one of the most common mycotoxin contaminants of wheat, barley, maize, and cereal-based food products (Canady et al., 2001; Schothorst and van Egmond, 2004). Like other trichothecenes, DON induces a spectrum of effects in farm and laboratory animals including emesis (DON has the trivial name ‘‘vo...

Deoxynivalenol (DON) concentrations in mature wheat grain are usually correlated with symptoms produced by Gibberella zeae infection. However, there have been numerous observations of unacceptably high DON in asymptomatic crops, which can lead to lower-than-expected milling reductions in DON. We conducted a field experiment with winter wheat to examine the effect of infection timing and postant...

The structure of transportation networks and the patterns of accessibility they give rise to are an important determinant of land prices, and hence urban spatial structure. While there is ample evidence on the cross-sectional relationship between location and land value (usually measured from the value of improved property), there is much less evidence available on the changes in this relations...

Early work in augmented reality grew out of virtual reality research domains. These initial augmented reality systems applied the same methods and technology to solve what at first appeared to be a similar problem: correctly render a scene of virtual objects as the user changes viewpoint in the world. This is indeed similar for augmented and virtual reality systems. In virtual reality systems o...
