In algebraic geometry, a closed immersion of schemes is a morphism of schemes that identifies Z as a closed subset of X such that locally, regular functions on Z can be extended to X. The latter condition can be formalized by saying that is surjective. An example is the inclusion map induced by the canonical map . (Wikipedia).

How open center hydraulic system works
Hi this video explains about the open center hydraulic system. Hydraulic systems are of two types: 1. Open center hydraulic system. 2. Closed center hydraulic system. This video explains only about the open center hydraulic circuit. For a work to happen in a hydraulic circuit or system t
