Determination of small amounts of sulphur as sulphates in biological fluids

A simple biological method for determination of small amounts of tuberculostatic agents in fluids.

The authors describe the use of the vertical diffusion test for determining the quantity of certain tuberculostatic drugs in body fluids and the degree of mycobacterial susceptibility to these drugs, using tubercle bacilli as test organisms. It is found to be a reliable assay method for isoniazid, para-aminosalicylic acid, ethionamide and ethambutol when carried out on a modification of Middleb...

The estimation and recovery of dextran sulphates in biological fluids.

The dextran sulphates resemble heparin in being active inhibitors of several different forms of biological activity, e.g., blood coagulation, serum complement activity, and certain enzyme systems (Walton, 1954). In each case the activity of the dextran sulphate appears to be dependent upon direct interaction with one or more protein components of the biological system under investigation. In fa...

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...
