THE QUALITATIVE EXAMINATION OF URINARY CALCULI

Simplified qualitative chemical analysis for urinary calculi.

OXALATE Stone powder (2-3 mg) is moistened on an ordinary glass slide with two to three drops of 20% nitric acid and is slowly heated over a small flame to dryness and then for a further 5-10 seconds but without charring. The following results may be noticed: (a) formation of a conspicuous reddish-brown froth indicating ammonium urate; (b) formation ofa flat purplish-brown layer, evidence of ur...

Urinary calculi.

IJANTITATIVE CHEMICAL ANALYSES of urinary calculi have been done in these laboratories for some twenty years. During this time almost two thousand stones have been examined. In the early days of this period, the only quantitative method available was that of a complete analysis of the inorganic ions and organic compounds present, which was quite difficult and tedious. After the development of t...

Qualitative Constraint Calculi

Until now world models in robotic soccer have been mainly quantitative in nature, consisting of fine-grained (numerical) estimates of player positions, ball trajectories, and the like. In contrast, the concepts used in human soccer are largely qualitative. Moving to qualitative world models also for robots has the advantage that it drastically reduces the space of possible game situations that ...
