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 constituencies, while local elections currently use constituencies of between five and seven seats. For European elections Northern Ireland serves as a single three-seat constituency. Local elections in Scotland use constituencies of three or four seats. All official STV elections in the UK use the Gregory method of counting votes. STV is also used by many private organisations. For example, it is used in many British university students' unions (and promoted by the National Union of Students as the fairest way of running elections), for all elections within the University of Cambridge and for electing board members in The Co-operative Group.
