determination of maximal singularity free zones in the workspace of parallel manipulator

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

Determination of ketone bodies in blood and urine by means of vanillin in alkaline medium.

& A PREVIOUS COMMUNICATION (1) we have reported that vanillin reacts with a large number of organic compounds with a carbonyl group, with aldehydes, and particularly with ketones, diketones, and ketonic acids to produce yellowish, or yellowish-red color complexes. Because of its wide reactivity the vanillin-alkali reagent cannot be used for any specific carbonyl compound unless it is first sepa...

Determination of ketone bodies in blood by headspace gas chromatography-mass spectrometry.

A gas chromatography-mass spectrometry (GC-MS) method for determination of ketone bodies (β-hydroxybutyrate, acetone, and acetoacetate) in blood is presented. The method is based on enzymatic oxidation of D-β-hydroxybutyrate to acetoacetate, followed by decarboxylation to acetone, which was quantified by the use of headspace GC-MS using acetone-(13)C(3) as an internal standard. The developed me...
