Single-use bioreactor providing a family of single-use bioreactors from bench-top to full-scale production. Three challenges exist for faster and greater single use bioreactor adoption 1) higher quality and lower cost disposable bags and containers, 2) more reusable and disposable sensors and probes that can provide high quality analytics including real-time cell culture level data points, and 3) a family of bioreactors from lab to production that has full scale-up of the bioprocess. Suppliers are working to improve plastic bag materials and performance and also to develop a broader range of sensors and probes that provide scientists greater insight to cell density, quality
History and use of the single transferable vote transferable vote system for elections in Denmark. Andræ's system was used in 1856 to elect the Danish Rigsdag, and by 1866 it was also adapted for indirect elections to the second chamber, the Landsting, until 1915.
