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!).
How Often. When you are on your period, make sure you should never leave a tampon in for more than eight hours. Use a higher absorbency tampon if you tend to change your tampon more frequently. After putting it for eight hours, change it after finding that if it is slightly dry or not. If it is becoming uncomfortable for you, then you should switch to a lower absorbency tampon.
