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!).
Dr. Kroman says... The general rule for wearing tampons is to change every 3-4 hours; earlier if it fills up; or after a maximum of 8 hours. Sleeping with a tampon is not a problem so long as you change it at around 8 hours. Make sure you pop it in just before you go to sleep and change it as soon as you wake up.
