Synthesis and characterization of nanostructured ZnO- and BiFeO3-Based Multifunctional Materials
(2012)
The effective incorporation of dopant species into ZnO host structure usually induces changes in its physical and chemical properties enabling the establishment of novel multi-functional properties. In the case of doping ...
Efectos de bioestimulantes para sistemas orgánicos y sustentables en limón ‘Tahití’ (Citrus latifolia Tanaka)
(2012)
Experiments were conducted during 2010 and 2011 in Lajas, Puerto Rico, to determine the effects of two biostimulants (agricultural formulations of an Ascophyllum nodosum extract and a blend of amino acids + potassium) on ...
Characterization of solid dispersions of hydroxypropyl cellulose films with griseofulvin via hot-melt extrusion
(2012)
Hot-melt extrusion has gained significance in the pharmaceutical industry to formulate solid dispersions. In a solid dispersion, poorly-water soluble drugs can be dispersed in an inert hydrophilic polymer matrix, improving ...
Feeding trials of Pangasius hypophthalmus larvae, during the first 2 weeks post hatching
(2012)
A high mortality in the first two weeks after hatching makes Pangasius hypophthalmus culture challenging. Some scientists have attributed this mortality event to cannibalism and bacterial infection. Larvae were presented ...
Estimación de densidades multivariadas en flujo de datos usando mezclas adaptativas de componentes gaussianas
(2012-06)
In the current world of science and technology the data arrive continuously over time, this type of data is called data stream and is impractical to store all of the data. The data mining and traditional techniques of ...
Wind turbine modeling for computational fluid dynamics
(2012-05)
With the shortage of fossil fuel and the increasing environmental awareness,
wind energy is becoming more and more important. As the market for wind
energy grows, wind turbines and wind farms are becoming larger. ...
A mimo modeling framework using a software defined radio paradigm
(2012)
This thesis presents the theory, design, and implementation of a computational framework for modeling MIMO (Multiple Input Multiple Output) systems and simulate them under the Software Defined Radio paradigm. Likewise, it ...
Satisfacción laboral en la profesión de enfermería en un hospital del suroeste de Puerto Rico
(2012)
The main objective of this investigation was to identify the factors that affect labor satisfaction at a health institution of the southwest region of Puerto Rico. A questionnaire was created to obtain nursing professionals ...
