Possible role of adenine and thymine rich sequence in the encapsidation pattern of Parvovirus LuIII
(2007)
LuIII is a small, non-enveloped, icosahedral autonomous parvovirus that contains a small
linear (5 kb) single stranded DNA genome and infects human cell lines lytically with no
evidence of integration into cellular DNA. ...
Supercritical fluid processing of sulfonated styrenic tri-block polymers
(2005)
The increasing need to replace current materials with new or reprocessed
ones that have more specific properties and uses has led to the use of supercritical
fluids (SCFs) for polymer reprocessing. Kraton® poly ...
Seasonal shoreline changes along the north coast of Puerto Rico, from Isla de Cabras to Aguadilla
(2007)
Seven beaches were studied along the north coast of Puerto Rico in order to qualitatively compare seasonal changes for each system. These are Punta Borinquen, Aguadilla, Jobos, Isabela, Camuy, Arecibo port, Mameyal, Vega ...
Effects of thermal oxidation of gamma titanium aluminide on human osteoblast adhesion
(2009)
The corrosion resistance of gamma titanium aluminide (gamma-TiAl), a potential
implant material, is increased in vitro by thermal oxidation. Although the biocompatibility of
autoclaved gamma-TiAl was previously demonstrated, ...
Clasificación noparamétrica en datos direccionales
(2004)
In a supervised classification problem, when the vectors of data are direction- al, it means, that they take values on a k-dimensional sphere, the application of the algorithms of pattern recognition as k-nearest-neighbour ...
Solubilities of anti-cancer and anti-AIDS drugs in supercritical carbon dioxide
(2003)
Solubility data for pharmacological drugs in supercritical fluids (SCFs) is of great
importance, because there is an environmental and cost effective need for alternative
specialty separation methods.
This research was ...
