Propolis Propolis Propolis or bee glue is a resinous mixture that honey bees produce by mixing saliva and beeswax with exudate gathered from tree buds, sap flows, or other botanical sources. It is used as a sealant for unwanted open spaces in the hive. Propolis is used for small gaps (approximately or less), while larger spaces are usually filled with beeswax. Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky at and above , while at lower temperatures, it becomes hard and brittle. While foraging, worker bees primarily harvest pollen and nectar,
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.
