16 inch composite material telescope with adaptive optics.key components: wavefront reconstructor & vibration testing
(2006)Advances in technology has provided means for astronomical optical telescopes to increase the aperture diameter (more light collecting capability) therefore increasing the resolution. Better resolution allows telescopes ... -
3D collagen scaffold for peripherial nerve regeneration
(2018-05)The nerve regeneration process is a complex pathway that most of the time is not completed and represents a life of limitations for people that suffers from injury or diseases that compromises neuron functionality involving ... -
3D high-speed photography for characterization of drag and lift fluctuations of a single rising bubble
(2020-12-11)Understanding the bubble motion in fluids is a topic of great interest in multiple applications in nature because of the significant impact and influence that this type of phenomenon has in numerous fields of engineering ... -
Above ground forest biomass and carbon status in the Rio Grande de Arecibo watershed
(2005)Tropical forest ecosystems, especially young secondary-rapid growing forests, naturally or artificially developed, have great potential for long term carbon sequestration and storage. This ecosystem function helps to ... -
Absorción de CD por Brachiaria Brizantha y Chloris Gayana en tres suelos con diferentes propiedades químicas, físicas y mineralógicas.
(2011)Phytoremediation is an ecologically friendly, cost effective technique that uses plants to remediate contaminated soil and water. One of the objectives in this study is to evaluate the absorption of cadmium (Cd) by two ... -
Abundance, composition and survivorship of juvenile corals in the southwestern Puerto Rico, la Parguera
(2006)The distribution, abundance, species composition and survivorship of juvenile corals over natural substratum were quantified in 6 reefs along the insular shelf off La Parguera Puerto Rico from August 2003 to August 2005. ... -
Abundancia y composición de las comunidades zoopláncticas sobre los arrecifes coralinos en Isla Desecheo, Puerto Rico
(2005-05)A study of zooplancton taxonomic composition and abundance was performed in the vicinity of Puerto Canoas and Puerto Botes reefs in Isla Desecheo. The main objective of the study was to examine the influence of the coral ... -
Abundancia y distribución de Pontodrilus litoralis en las costas cercanas al Faro de Cabo Rojo, Puerto Rico
(2010)The purpose of this investigation was to determine the structure and dynamics of the populations of the oligochate Pontodrilus litoralis on the coasts near the Cabo Rojo Lighthouse in Puerto Rico. During the months of ... -
Acceleration of finite field arithmetic with an application to reverse engineering genetic networks
(2008)Finite field arithmetic plays an important role in a wide range of applications. This research is originally motivated by an application of computational biology where genetic networks are modeled by means of finite fields. ... -
Accumulation and elimination of copper by the flat-tree oyster Isognomon alatus
(2007-05)A baseline study of copper concentrations in I. alatus from Bioluminescent Bay during May 2004 to June 2005 was conducted. In general, average copper levels were (7.64-17.1 μg/g dry wt), which are lower than those previously ... -
Acerca de las formas torcidas sobre los grupos lineales algebraicos
(2008)Working from the Galois theory, we define linear groups via group schemes. We study different properties of these groups such as connectedness, Lie algebras associated to them, which determine their smoothness. Lastly we ... -
Aclimatación precoz y suplementación dietética con vitamina e y zinc como alternativas para el manejo del estrés calórico en pollos de engorde
(2008)The production of broiler chickens in open houses with minimal control of the environment typically takes place in areas of high temperatures causing bird stress and negative effects on the industry. There are diverse ... -
Acople de HSPF - Un modelo de simulación hidrológica con CE-QUAL-W2 de calidad de agua en el Lago Cerrillos, Ponce, Puerto Rico
(2014)Este documento presenta el acople del modelo de simulación hidrológica HSPF (Hydrologic Simulation Program FORTRAN) y el modelo de calidad de agua en lagos (CE-QUAL-W2), realizado en la cuenca del Río Cerrillos y su ... -
An acoustic method for real time air bubble detection in simulated blood vessels
(2012)Exposure to significant changes in ambient pressure commonly occurs in divers during surfacing. These changes induce the formation of nitrogen bubbles in tissues and the presence of these bubbles can cause symptoms of ... -
Acoustic signal representation for environmental surveillance monitoring (esm)
(2007)This work presents an integrated development framework, with scalable and reconfigurable hard- ware/software co-design components, for space-time computational signal processing embed- ded system applications such as ... -
Acoustically monitoring coral reef fishes to determine short-term spatial and temporal movement and habitat utilization patterns
(2009-03)The spatial and temporal movement and habitat utilization patterns of coral reef fishes were quantified using acoustic telemetry on 16 coral reef fish taken from 9 species across 5 families. Fish were caught in traps and ... -
Acquiring multispectral information using computer tomography imaging spectrometer based algorithms
(2019-10-07)Spectral imaging has been used by scientists to acquire information across the electromagnetic spectrum for remote sensing applications. Most of the spectral systems are based on scanning methods that rely mainly on ... -
