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!).
Tampons should be changed every 4-6 hours, as stated above pads should be used with light flow and overnight, alternate with pads as often as possible, and always use lowest absorbency for your flow. If misusing tampons it will increase your risk of developing vaginal infections and cause vaginal irritation.
