Rouleaux formation is retarded by albumin proteins. Rouleaux formations are also adopted by spermatozoa as a means of cooperation between genetically similar gametocytes so as to improve reproductive success through enhanced motility and, therefore, fertilization capacity—e.g., the guinea pig.
rouleaux, a stack of red blood cells (textiles) A decorative technique that involves creating patterns with piping, cording or bias tape. A rouleau loop uses the same cord or piping as a way of fastening buttons, most notably down the back of bridal gowns.
Rouleaux formation also determines Erythrocyte sedimentation rate which is a non-specific indicator of the presence of disease. [ 6 ] Influence of erythrocyte aggregation on in vivo blood flow is still a controversial issue. [ 7 ]
Gambian dalasi coin, a Reuleaux heptagon. In geometry, a Reuleaux polygon is a curve of constant width made up of circular arcs of constant radius. [1] These shapes are named after their prototypical example, the Reuleaux triangle, which in turn is named after 19th-century German engineer Franz Reuleaux. [2]
The boundary of a Reuleaux triangle is a constant width curve based on an equilateral triangle. All points on a side are equidistant from the opposite vertex.
Rouleau / ˈ r oʊ l oʊ / is a town in southern Saskatchewan, Canada, on the Canadian Prairies. It lies within census Division No. 6 and Rural Municipality of Redburn No. 130 . As of 2021, the population was 505 (a decrease of 6.5 percent from the 2016 census), in an area of 1.65 square kilometres (0.64 sq mi).
The Public Order Emergency Commission (POEC; French: Commission sur l'état d'urgence), also known as the Rouleau inquiry or the Inquiry into Emergencies Act was a public inquiry in Canada that investigated the invoking of the Emergencies Act on February 14, 2022, by the government of Prime Minister Justin Trudeau during the Canada convoy protests.

Bonnesen and Fenchel [4] conjectured that Meissner tetrahedra are the minimum-volume three-dimensional shapes of constant width, a conjecture which is still open. [5] In 2011 Anciaux and Guilfoyle [6] proved that the minimizer must consist of pieces of spheres and tubes over curves, which, being true for the Meissner tetrahedra, supports the conjecture.
