Moisture effects on short term durability and mechanical properties of two Puerto Rico crushed limestone aggregates
This Master of Science thesis includes an experimental characterization of the mechanical properties of two Puerto Rico crushed limestone aggregates (CLA). Specifically, the crushed limestone was obtained from two quarries ...
Análisis y reconstrucción del decaimiento hadrónico j J/ψ→ K+K−π+π−π0
Se determinó la razón de producción para el decaimiento hadrónico J/ψ→ K+K−π+π−π0 y se realizó una comparación con los valores obtenidos en un análisis previo basado en una muestra de 3 millones de eventos de ψ(2S) para ...
Remote sensing of suspended sediment in Mayagüez bay associated with Inland soil erosion rates
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
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
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, ...
