(2009)
A complete randomized block design - split plot arrangement with four repetitions was used to identify the best source and the appropriate level of calcium for increased the performance and quality of papaya (Carica papaya). ...
Analysis of optimal matching between a dc motor and photovoltaic modules via dc-dc power converters
(2009)
Due to the nonlinear behavior of the photovoltaic (PV) cells, dc-dc power converters are added for matching the load to the photovoltaic generators; thus, maxi- mum power can be reached. In this thesis, mathematical models ...
Design of a parabolic reflector and reflectarray antenna for x-band
(2011)
The design of a circular aperture planar reflectarray at 9.4Ghz center frequency is presented in this thesis. For the first time, an aperture coupled cross shaped patch is used as a cell element for a reflectarray antenna. ...
Khovanov homology for almost alternating knots
(2017)
The large quantity of almost alternating knots gives rise to an important category in knot classification. We thus establish a result, previously given for the span of the bracket polynomial for almost alternating knots, ...

(2010)
Existe un gran interés por el posible uso del sorgo como henilaje, ya que esta forrajera tiene muchas características deseables tales como gran resistencia a las sequías, buen rendimiento, adaptabilidad a diferentes tipos ...
Application of the Sr-U coral paleo-thermometer to reconstruct sea surface temperatures during the Mid-Holocene using corals from Cañada Honda, Dominican Republic
(2018-05)
The skeletons of massive corals provide important seasonally resolved archives of past climate as
they provide strong temporal constraints. Current coral paleo thermometers (δ18O and Sr/Ca) have
proven to provide valuable ...
In search of pre-columbian migrations to the Caribbean: indigenous mitochondrial DNA from Northern South America
(2009)
In an effort to gain a better understanding of the migratory processes related to the peopling of the Caribbean, the aim was to characterize Native American mtDNAs from Colombia and Venezuela and compare them to their ...
Response of the common bean (Phaseolus vulgaris L.) to Rhizobium inoculation and nitrogen fertilization
(2009)
Common bean (Phaseolus vulgaris L.) producers need to use bean lines with improved nitrogen (N) use efficiency to decrease production costs. The goal of this thesis was to identify bean lines adapted to soils with low N ...
