Turbo roundabout - An alternative to classic two lane roundabout
Put i saobraćaj, 2023 Traffic congestion and the questionable safety of two-lane roundabouts are two justified criteria for the introduction of turbo roundabouts. The increase in capacity, which also results in an increase in the level of service, is a positive aspect of this alternative type of roundabout.

A Roundabout Way to Cancer [PDF]
, 2012 The Slit family of secreted proteins and their transmembrane receptor, Robo, were originally identified in the nervous system where they function as axon guidance cues and branching factors during development. Since their discovery, a great number of additional roles have been attributed to Slit/Robo signaling, including regulating the critical ...

A Roundabout Way to the Niche [PDF]
Cell Stem Cell, 2011 A new player in hematopoietic stem cell (HSC)-niche interactions is introduced in this issue of Cell Stem Cell. Smith-Berdan et al. (2010) demonstrate that Robo4 is involved in HSC engraftment and mobilization and does so in cooperation with Cxcr4 to guide stem cells to and secure them in the niche.
