Propolis while also collecting water and tree resin necessary for the production of propolis. The chemical composition and nature of propolis depend on environmental conditions and harvested resources. For centuries, beekeepers assumed that bees sealed the beehive with propolis to protect the colony from the elements, such as rain and cold winter drafts. However, 20th century research revealed that bees not only survive, but also thrive, with increased ventilation during the winter months throughout most temperate regions of the world. Propolis properties may include: The composition of propolis varies from hive to hive, from district to district, and from season to
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.
