The lack of a universal simulation method for triboelectric nanogenerator (TENG) makes the device design and optimization difficult before experiment, which protracts the research and development process and hinders the landing Milk of practical TENG applications.The existing electrostatic induction models for TENGs have limitations in simulating T

Examination of stomach contents of the brown trout is a sensitive method to evaluate the animals occurring in a lake and its surroundings.Yearly test fishing from Lake Sandvatn at the Hardangervidda Mountain plateau in August has shown regular occurrence of Bibio pomonae in the brown trout stomachs every third year since 2001.The stomach fullness a
