Measurements have been made of the pressure drop due to forced convective flow of sub-cooled water in narrow heated channels near atmospheric pressure. A correlation for the minima of these curves is presented as an aid to the preliminary assessment of the conditions under which excursive-flow instability can take place. A possible basis for a more general criterion for assessing the locus of the pressure-drop minima is also presented.
Nuclear magnetic resonance (NMR) spectroscopy combined with a statistical classification strategy (SCS) successfully distinguished between Candida albicans and Candida dubliniensis. 96% of the isolates from an independent test set were identified correctly. This proves that this rapid approach is a valuable method for the identification and chemotaxonomic characterisation of closely related taxa. Most discriminatory regions
were correlated with metabolite profiles, indicating biochemical differences between the two species.
Multichannel reflection seismic profiles extending southward from the Grand Banks show gently dipping reflectors within “basement” features underlying Nike Free Uk Online
the Newfoundland Ridge. These reflections appear to be from sedimentary strata, indicating that the Newfoundland Ridge is a remnant of a Nike Roshe Run Trainers Black
former sedimentary basin, rather than a ridge of oceanic crust as prescribed by plate tectonic models. Probably this feature is underlain, and to some extent surrounded by, continental crust.
