Quantitative Determination of Agar in Seaweeds

Methodology for quantitative determination of the carbohydrate composition of brown seaweeds (Laminariaceae)

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 perchlorate and iodide concentrations in edible seaweeds

Perchlorate and iodide concentrations were determined in brown (Undaria pinnatifida and Laminaria japonica) and red (Porphyra sp.) edible seaweeds, which are commonly consumed by Korean people, with the use of ion chromatography, coupled with a tandem mass spectrometer. Seaweeds (i.e., good sources of iodine) are among the most important plant life in the ocean and commonly consumed as food and...

Determination of mammalian cell (strain HeLa) inhibition by an agar diffusion technic. I. Quantitative assay methods.

Paper chromatography has proved to be a powerful tool in an antibiotic screening program (1). It serves the following purposes: (a) it pro vides an early characterization of the antibiotic activity as new or old, (6) it determines whether single or multiple activities are present, and (c) it predicts the solubility characteristics of the activ ity and probable extraction behavior. Thus, at a ve...

Quantitative Determination of Azadirachtin in Melia indica and M. azedarach

Background: Melia indica and M. azedarach (Meliaceae) are widely used in traditional medicine. These species are considered as natural pesticides. Their major compound is azadirachtin (AZD) which is considered as the marker for quality control of these species. Objective: In the present investigation, AZD content of the leaves and fruits (comprising the whole fruit, peel, pulp and seeds) of M....
