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!).
While unlikely, tampons can cause toxic shock syndrome (TSS), a potentially deadly disease. Higher absorbency tampons increase the risk of TSS, so it's smart to use them only when you absolutely need to stop a super-heavy flow. Your flow can change from day to day throughout your period. So while supers might be a godsend on days one and two of your period, you'll want to switch to regular or light absorbency tampons toward the end of your period (or whenever your flow tapers off). 4. You only change your tampon once a day.
