Single V promotional videos from a varying span of time, alternate versions of the videos, often featured on the Single V that the video originally came from, and the TV spots for the singles. Although Hello! Project singles are usually accompanied by a Single V, frequently when a single is released near the same time that a Single V Clips is released, the single will not have a regular Single V. Instead, the promotional video and alternate shots of the video will appear on the Single V Clips. But no one knows what the "V" or "M" actually means. Single V A
Single-use bioreactor validation procedures can be made easier, and will finally lead to significant cost reductions. The application of single-use bioreactors reduces the risk of cross contamination and enhances the biological and process safety. Single-use applications are especially suitable for any kind of biopharmaceutical product. Single-use bioreactors contain fewer parts compared with conventional bioreactors, so the initial and maintenance costs are reduced. Limiting factor for the use of "some" single-use bioreactors is the achievable oxygen transfer, represented by the specific mass transfer coefficient (k) for the specific phase area (a), resulting in the volumetric oxygen mass transfer coefficient (ka). Theoretically this can
