Implications of finite-size and surface effects on nanosize intercalation materials
(2000-03)
A Monte Carlo simulation of a two-dimensional lattice gas with free boundaries is used to study
the effects of surface and size on the chemical potential-composition curves of intercalation
compounds. In particular we are ...
Influence of sample oxidation on the nature of optical luminescence from porous silicon
(2000-07)

Impact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
(2000)
The objectives of the research program reported upon here were (1) to measure ambient levels of UV radiation and determine which variables most strongly affected its attenuation in the waters of the estuary and Gulf of St. ...
Modeling the effects of ultraviolet radiation on embryos of Calanus finmarchicus and Atlantic cod (Gadus morhua) in a mixing environment
(2000-12)
It is well established that ultraviolet radiation (UVR, 280-400 nm) harms aquatic organisms. Reductions in productivity have been reported for phytoplankton, ichthyoplankton, and zooplankton in incubations exposed to UVR. ...
Suppression of intervalley scattering in Ga(As)Sb quantum wells

Coastal food web structure, carbon storage, and nitrogen retention regulated by consumer pressure and nutrient loading
(2000-03)
By factorial field experiments we analyzed the relative effects of increased nutrient (N+P) loading and natural grazing pressure on species composition, carbon storage, and nitrogen retention in the Baltic Sea littoral ...
Cyclical behavior in early universe cosmologies

Quantum dynamics of pseudospin solitons in double-layer quantum wall systems (vol 83, pg 1411, 1999)

Deep structure of the ocean-continent transition in the southern Iberia Abyssal Plain from seismic refraction profiles: The IAM-9 transect at 40 degrees 20 ' N
(2000-03)
We present a crust and mantle velocity structure for the West Iberia passive continental margin derived from a 320-km-long wide-angle seismic profile acquired in the southern Iberia Abyssal Plain. We observe a 170-km-wide ...
Temporal and spatial variability in settlement and recruitment of echinoderms in kelp beds and barrens in Nova Scotia
(2000-10)
Settlement and recruitment of echinoderms were measured in 2 adjacent habitats: a kelp bed
(Laminaria longicruris) and an echinoid (Strongylocentrotus droebachiensis)-dominated barren ground
at each of 2 sites in the ...
