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 code in a separate glue language. Glue code is very efficient in rapid prototyping environments where several components are quickly put together into a single language or framework. Because each component is independent (i.e. it is unaware of its relations and is only connected to another component through glue code), the behavior of a component and its interactions can change during the execution of the script. In addition, a different version of one of the components may behave differently, breaking the glue code. High-level programming languages can suffer from performance penalties because glue code must run through the language interpreter, even
