Two venous cannulae were inserted to connect the ABS system and the reference system.

First, he had to establish some kind of reference system.

Objective: The aim was to establish a reliable reference system for biochemical measurements in endomyocardial biopsies.

They were still essentially in zero gravity, and the brain could select any reference system it pleased.

To give scientists and researchers consistency, LINZ has developed a new vertical datum, a reference system based on gravity.

Non-collagen protein content was evaluated as a non-specific reference system and compared with total creatine content representing a specific myocardial reference system.

Employment of total creatine as a reference system does not reduce variability of myocardial metabolite determinations in endomyocardial biopsies compared with non-collagen protein.

The method relies on an image registration technique based on fiducial external markers to realign, spatially, PET images with the CT spatial reference system.

Finally, the SGML markup incorporates existing canonical reference systems (chapter, verse, line, etc.

Results: We have found progressive decrease of mean telomere length in all cancer subtypes compared with reference systems.

Comparison of variability in myocardial ATP content with non-collagen protein or total creatine as reference systems revealed no difference.

Four laboratories measured the activity of a (64)Cu solution; these results were compared through the International Reference System.

In the semi-finals Donegal's much- referenced system derailed a Dublin team regarded as shoo-ins for back-to-back All-Irelands and made the winners clear favourites for the final.
