After weaning, groups of rats were fed a semi-purified diet containing fiddlehead greens (the unfuried frond of the ostrich fern Matteuccia struthiopteris), mature bracken fern (Pteridium aquilinum), or cycad meal (Cycas circinalis), or this diet plus aflatoxin B1. The groups fed 1-10% fiddlehead greens for 70-73 weeks developed no tumors, whereas those fed mature bracken fern for 67 weeks deve...

In 1998, researchers at the University of Maryland discovered a new disease of creeping bentgrass caused by an unidentified species of Ophiosphaerella. Through morphological and molecular study, it was shown that the pathogen constituted a new species, Ophiosphaerella agrostis, and the disease was named bentgrass dead spot. Subsequently, O. agrostis was found in Texas and Florida causing dead s...

We have conducted joint research studies on the management of brown ring patch since 2010. From a feld research perspective, this disease has been challenging to work with because it is diffcult to fnd naturally infected putting greens with uniform disease incidence and severity. The main body of research presented in this paper comes from work conducted in 2010 and 2011 on a putting green in N...

This paper reviews major studies in three traditional lines of research in residential energy consumption in the UK, i.e., economic/infrastructure, behaviour, and load profiling. Based on the review the paper proposes a three-dimensional model for archetyping residential energy consumers in the UK by considering property energy efficiency levels, the greenness of household behaviour of using en...

The space-time Greens functions for 3-D poststack and 3-D prestack migration in a homogeneous medium are derived under the fareld approximation. These Greens functions can be used to practically compute synthetic migrated images. Examples are given for the recording footprint noise associated with a point scatterer and a meandering river channel. The Greens functions also provide fundamental in...

Two-tiered putting green profiles feature a sand root zone that sits above a layer of gravel, creating a textural boundary where water is perched or preferentially retained (6). The greater the difference in particle sizes, the more water is retained in the fine-textured layer above (8). Hard, brittle, cemented layers have been observed to form at textural boundaries in two-tiered putting green...

Abstract We develop a theoretical framework and presents corresponding empirical analysis of the Food Drug Administration’s irrigation water quality regulatory standard under Safety Modernization Act using lettuce as case study. stochastic price endogenous partial equilibrium model with recourse to examine standard’s efficacy various scenarios foodborne illness severity, implementation, demand ...

The intense investigations of molecular devices, as an alternative to standard electronics components, underlines the need to model the conduction mechanisms of nano-scale conductors. In addition to measurements of the elastic conductance through point-contacts, atomic-wires and molecules, recent experiments have shown inelastic tunneling currents through, for example, a hydrogen molecule attac...
