Benthic foraminiferal δ¹³C data from site 502 in the Caribbean Sea (sill depth 1800 m) indicate that throughout the past 2.6 m.y., glacial δ¹³C values in the middepth Atlantic were higher during glaciations than interglaciations. This is interpreted as indicating a greater proportion of Upper North Atlantic Deep Water (UNADW)...
The adsorption equilibrium and kinetic behavior exhibited
by β-lactoglobulin at silanized silicon surfaces of varying
hydrophobicity were examined using ellipsometry. Adsorption
equilibrium results were used to construct adsorption
isotherms; the adsorbed mass of β-lactoglobulin was observed
to increase with increasing surface hydrophobicity, within a
defined range of hydrophobicity. Adsorption kinetics...
The relative enrichment of skin sebaceous gland lipids with deuterium-labeled α-tocopherol was compared with plasma enrichment to evaluate the delivery of vitamin E to skin. For the first week of this study, each subject consumed a daily dose of deuterated vitamin E (150 mg of an equimolar mixture of RRR-α-[5-(C²H₃)]-(d₃)...
En mayo de este año, la Revista Panamericana de Salud Pública dedicó un número especial a promover el proceso más reciente de reforma de salud en Ecuador como un caso exitoso en la región. En el artículo editorial, la directora de la Organización Panamericana de la Salud (OPS), Carissa Etienne,...
What does comida rica mean? In this thesis, I explore the meanings of comida rica, sana, and de nuestra tierra through the discourses, practices, and kitchen geographies in six urban, highland households in the Ecuadorean Andes. This research, as part of a larger investigation carried out by a team of...
exceptional examples of the Nation’s biological and geological features. To qualify for
NNL designation, a site must be one of the best examples of a geological or biological
feature within a biophysiographic province. Zumwalt Prairie represents a perfect example
of this concept, containing one of the largest remnants of native...

The marine climate of the Galapagos is spatially and seasonally
heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has
never been done. This study is an initial effort to establish the distribution and
community structure of zooplankton in the Archipelago. I collected zooplankton
samples by vertical tows over the Galapagos...
