Propolis propolis has approximately 50 constituents, primarily resins and vegetable balsams (50%), waxes (30%), essential oils (10%), and pollen (5%). Propolis also contains persistent lipophilic acaricides, a natural pesticide that deters mite infestations. In neotropical regions, in addition to a large variety of trees, bees may also gather resin from flowers in the genera "Clusia" and "Dalechampia", which are the only known plant genera that produce floral resins to attract pollinators. "Clusia" resin contains polyprenylated benzophenones. In some areas of Chile and Argentina Andean valleys, propolis contains viscidone, a terpene from "Baccharis" shrubs, and in Brazil and Paraguay, naphthoquinone epoxide has
Glue (software) Glue (software) glue (spelled with a lower-case "g") is a linked-view data visualization package written in python.. glue, as working visualization software, was created and realized in 2012, after being described as a work-in-progress in "Principles of High-Dimensional Data Visualization in Astronomy". Using glue, users can create scatter plots, histograms and images (2D and 3D) of their data. Glue is focused on the brushing and linking paradigm, where selections in any graph propagate to all others. Glue uses the logical links that exist between different data sets to overlay visualizations of different data, and to propagate selections across data sets.
