However, many alternative monitoring technologies have emerged over the last decades, from esophageal Doppler to bioimpedance tracheal tubes [22], bioreactance skin patches [23] and pulse contour methods.
Two of the many alternative energy technologies that scientists have been experimenting with during the past four decades -- solar and biofuel -- have matured to the point where they can make the world largely free of fossil fuels in as little as a few decades.
In this development and design process many alternative options become excluded in favour of the technology that is now available obviously with important social and normative implications.
These numbers suggest that many alternative splicing events are differentially expressed but go undetected by current gene expression profiling technologies.
RDF technologies provide a domain-independent way for representing knowledge and their open nature assures many alternative approaches for making data available as RDF.
Designers usually work on many alternative schemes.
Dr Le says: "We have to develop alternative technologies.
They both promise to promote alternative technologies.
Many alternative solutions have been proposed.
