Cycle of research and development. Research and development (R&D or R+D), also known in Europe as research and technical (or technological) development (RTD), is a general term for activities in connection with corporate or governmental innovation. Research and development is situated at the front end of the innovation life cycle, which may end with commercialization.
Can I leave a tampon in overnight? Like all tampons in Australia, our U by Kotex tampons can be used for up to 8 hours, but not any longer. So, while it IS possible to wear a tampon overnight, we know that everyone has different absorbency needs, as well as different sleep patterns (letâs face it, we all like a sleep in sometimes!).
Remove the tampon when you're ready. Though you should remove a tampon every 6 to 8 hours at the longest, you may find that you will need to remove your tampon sooner if you're having a heavy flow. It's important to check on it every hour or two, especially when you're using tampons for the first time.
