A Chamberland filter , also known as a Pasteur–Chamberland filter , is a porcelain water filter invented by Charles Chamberland in 1884. [ 1 ] It was developed after Henry Doulton's ceramic water filter of 1827. It is similar to the Berkefeld filter in principle.
The filter consists of a permeable unglazed porcelain t... | https://en.wikipedia.org/wiki/Chamberland_filter |

A chamfer ( / ˈ ( t ) ʃ æ m f ər / SHAM -fər, CHAM - ) is a transitional edge between two faces of an object. Sometimes defined as a form of bevel , it is often created at a 45° angle between two adjoining right-angled faces.
Chamfers are frequently used in machining , carpentry , furniture , concrete formwork , mirr... | https://en.wikipedia.org/wiki/Chamfer |
In geometry , a chamfer or edge-truncation is a topological operator that modifies one polyhedron into another. It separates the faces by reducing them, and adds a new face between each two adjacent faces (moving the vertices inward). Oppositely, similar to expansion , it moves the faces apart outward, and adds a new ... | https://en.wikipedia.org/wiki/Chamfer_(geometry) |
In geometry , the chamfered dodecahedron is a convex polyhedron with 80 vertices , 120 edges , and 42 faces : 30 hexagons and 12 pentagons . It is constructed as a chamfer (edge-truncation) of a regular dodecahedron . The pentagons are reduced in size and new hexagonal faces are added in place of all the original edges... | https://en.wikipedia.org/wiki/Chamfered_dodecahedron |
A champagne flow is an astrophysical event whereby an HII region inside a molecular cloud expands outward until it reaches the interstellar medium. At that point, the ionized hydrogen gas bursts outward like an uncorked champagne bottle. This event is also sometimes called a Blister. [ 1 ] An HII region is created by i... | https://en.wikipedia.org/wiki/Champagne_flow_model |
In mathematics , the Champernowne constant C 10 is a transcendental real constant whose decimal expansion has important properties. It is named after economist and mathematician D. G.
