PREPARATION OF SERUM LIPIDE EXTRACTS FREE OF INORGANIC PHOSPHATE

Preparation of lipide extracts from brain tissue.

For the preparation of lipide extracts from tissues, the method of Bloor (I), either in its original form or with slight modifications, has been a standard procedure. This method consists in extracting the tissue with a mixture of ethyl alcohol and ether. Since the extract obtained is known to contain non-lipide contaminants, it is usually taken to dryness and the residue extracted with a solve...

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...

PREPARATION OF TRISUBSTITUTEDPYRIMIDINES USING FERRIC PHOSPHATE

Ferric phosphate accelerated condensation reaction of aldehydes, 1,3-dicarbonyl compounds and amuniom acetate refluxing ethanol that remains a common theme in current literature.

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
