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!).
A word of warning when using tampons: only use tampons when you have your period and put a new one in at least every four to six hours in order to prevent Toxic Shock Syndrome (TSS). TSS is a potentially deadly condition that occurs when there is too much Staphylococcus aureus, a type of Staph bacteria, in the body.
