(2009)
This study combined in situ optical measurements, satellite derived reflectance and geospatial data to evaluate total suspended sediment (TSS) spatial and temporal variations in Mayagüez Bay and their relationship with ...
Synthesis and characterization of polyimide cobalt ferrite nanocomposites for potential applications in mems
(2009)
In the present work, cobalt ferrite nanocrystals were synthesized under size-controlled conditions in aqueous phase and incorporated into a polyimide matrix at various volumetric loads. Synthesized 20nm-cobalt ferrite ...
Fijación biológica de nitrógeno y almacenamiento de carbon en agrosistemas de producción de carbono en agrosistemas de producción de café (Coffea arábica L.) en Puerto Rico
(2009)
Coffee agroforestry systems have been promoted because they have smaller environmental impact than sun grown coffee. The majority of shade grown coffee systems use leguminous trees capable of fixing N2 from the atmosphere, ...
