Domains & Kingdoms: Taxonomy of Cells Microscopes allow us to look closely at cells. There are many different types of organisms: three Domains comprised of Bacteria, Eukarya, and Archeae; and 4 Kingdoms of Eukarya: Plantae, Animalia, Fungi, and Protista. Each of the Domains has characteristi

Relational Properties of Domains* Andrew M. Pitts-Cambridge University Computer Laboratory, Pembroke Street, Cambridge CB23QG, England New tools are presented for reasoning about properties of recursively defined domains. We work within a general, category-theoretic framework for various notions of ''relation'' on domains and for actions

Entrepreneurial ecosystem models typically categorize the ecosystem elements into domains. The number and type of ecosystem domains vary from one model to another. There is a general consensus regarding the inclusion of some domains such as human capital, policy, and finance; other domains such as market access and quality of life are .
