Fullerene molecules such as C(60) are large nearly spherical shells of carbon atoms. Pairs of such molecules have a strong long-range van der Waals attraction that can produce scattering or binding into molecular crystals. A simplified classical-electrodynamics model for a fullerene is a spherical metal shell, with uniform electron density confined between outer and inner radii (just as a simpl...

soil water retention curve (swrc) is important in the studies of soil and water relationship, soil conservation, irrigation scheduling, drainage, solute transport, plant growth and crop water stress. the performance of 10 models (simons et al., libardy et al., campbell, farrell and larson, van genuchten, brooks and corey, driessen, exponential bruce-luxmore, power bruce-luxmore, and rogowski) w...

We have developed a model for the calculation of van der Waals force for layered systems with axial symmetry. Our result can be applied to compute the cohesion of a carbon nanotube to a substrate, the cohesion between nanotubes, and between shells of multiwall nanotubes. We have obtained unusal power laws for the distance dependence of the many-body van der Waals potential.

The Rijksmuseum has a number of nineteenth-century ship models once owned by the former naval officer and marine painter Jacob Eduard van Heemskerck Beest (1828-1894). One them, model earliest generation screw steamships with sails, hybrid traditional sailing steamship, recently been restored. During restoration it was found to have generic characteristics but specific identification function (...

In this paper diffuse interface models of surfactant-assisted liquid-liquid phase separation are addressed. We start from the generalized version of the Ginzburg-Landau free-energy-functional-based model of van der Sman and van der Graaf. First, we analyze the model in the constant surfactant approximation and show the presence of a critical point at which the interfacial tension vanishes. Then...

in Native language Dit artikel beschrijft een nieuwe kader voor onderzoek naar acceptatie van technologie. Drie niveaus worden beschouwd; persoonlijkheid, overtuigingen over technologie in het algemeen en overtuigingen aangaande een specifieke technologie. Het nieuwe kader word getest gebruik makend van respectievelijk het Five Factor-model, TRI en UTAUT.
