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 semantics syntactic formalisms have also been proposed; besides LFG, glue analyses have been proposed within HPSG, context-free grammar, categorial grammar, and tree-adjoining grammar. Glue is a theory of the syntax-semantics interface which is compatible not only with various syntactic frameworks, but also with different theories of semantics and meaning representation. Semantic formalisms that have been used as the meaning languages in glue semantics analyses include versions of discourse representation theory, intensional logic, first-order logic, and natural semantic metalanguage. Glue semantics Glue semantics, or simply Glue (Dalrymple et al. 1993; Dalrymple 1999, 2001), is a linguistic theory of semantic composition and the
