A virus binding to a surface causes stress of the virus cage near the contact area. Here, we investigate the potential role of substrate-induced structural perturbation in the mechanical response of virus particles to adsorption. This is particularly relevant to the broad category of viruses stabilized by weak noncovalent interactions. We utilize atomic force microscopy to measure height distri...

Stampfli A. 1992. Effects of mowing and removing litter on reproductive shoot modules of some plant species in abandoned meadows on Monte San Giorgio. Bot. Helv. 102: 85-92. Reproductive shoot modules have been counted in a permanent plot experiment on Monte San Giorgio (Southern Switzerland) since 1988. The 8 species presented here, including the dominant grass (Molinia arundinacea) and seven ...

of hysteria, and W. H. Walshe (Brome calls him "Walsh") is described as having studied with Laennec (he was fourteen years old when Laennec died). The publishers seem to have a limited amount of type with umlauts, so "fur" usually becomes "fur". I tired of noting misprints at about page 100, but in one notable paragraph of ten lines (p. 225), Cranefield became "Cranfield", Helmholtz became "Hem...

Switchgrass, Indiangrass, and big bluestem are warmseason grasses that are a suitable alternative for summer pasture in Iowa. Their advantage over cool-season grasses such as bluegrass, bromegrass, and orchardgrass is their ability to produce during midsummer. These warm-season perennial grasses start growing in late spring as air and soil temperatures increase. Leaf growth often occurs in earl...

An amended kinetic model for the self-assembly of empty capsids of brome mosaic virus is proposed. The model has been modified to account for a new feature in the assembly kinetics revealed by time-course light scattering experiments at higher temporal resolution than previously attempted. To be able to simulate the sharp takeoff from the initial lag phase to the growth phase in the kinetic cur...

We introduce uncertainty about farmer characteristics into the moral hazard problem facing a regulator offering agri-environmental contracts. Our model allows for a continuum of farmer compliance costs. For reasonable parameter values the model predicts high levels of cheating and intensive monitoring, contrary to the evidence. We therefore add variation in farmers’ propensity to cheat, the reg...
