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...
15 صفحه اولDetermination of dehydroisoandrosterone and 17-ketosteroids.
Methods for the quantitative determination of steroids have been developed, based on their specific chemical or physicochemical properties. The Zimmermann reaction (1) and the Kober reaction (2) have been found useful in the quantitative determination of certain individual steroids occurring in urine. Modifications of these reactions have been reported by Callow et al. (3), Holtorff and Koch (4...

متن کاملAbnormal 24-hr mean plasma concentrations of dehydroisoandrosterone and dehydroisoandrosterone sulfate in women with primary operable breast cancer.
The 24-hr mean plasma concentrations of dehydroisoandrosterone (DHA) and dehydroisoandrosterone sulfate were measured in 11 women with primary operable breast cancer, ages 31 to 78 years, and in 37 normal women, ages 21 to 75 years. In contrast to the marked and progressive decline of DHA and dehydroisoandrosterone sulfate concentration with age in the normal women, the concentrations of both s...
متن کاملStudy on the determination of heavy water in plasma or urine.
EBAL PROCEDURES are available for determination of deuterium in water by mass spectrometry. In the method of Solomon (1), water and deuterium oxide are reduced with hot zinc, and lative concentrations of deuterium and hydrogen are measured. ber of investigators have utilized this procedure in precise and ive studies (2-5). Other indirect methods were mentioned by burn et at. (6) in a study in w...
