Discrete Versions of the Beckman-Quarles Theorem

Let F ⊆ R denote the field of numbers which are constructible by means of ruler and compass. We prove that: (1) if x, y ∈ R (n > 1) and |x − y| is an algebraic number then there exists a finite set Sxy ⊆ R containing x and y such that each map from Sxy to R n preserving all unit distances preserves the distance between x and y; if x, y ∈ F then we can choose Sxy ⊆ F, (2) only algebraic distance...

Evaluation of the Beckman creatinine analyzer.

We compared results obtained with the Beckman Creatinine Analyzer (Beckman Instruments, Inc.) to those with the GEMSAEC Centrifugal Analyzer (Electro-Nucleonics, Inc.) and with a manual method for determination of creatinine in serum and urine. Linearity, stability, recovery, and precision were evaluated. Interference from bilirubin, protein, lipemia, uric acid, and hemolysis is negligible, but...
