    "abstract": "The mean electromotive force caused by turbulence of an electrically\nconducting fluid, which plays a central part in mean--field electrodynamics, is\ncalculated for a rotating fluid. Going beyond most of the investigations on\nthis topic, an additional mean motion in the rotating frame is taken into\naccount. One motivation for our investigation originates from a planned\nlaboratory experiment with a Ponomarenko-like dynamo. In view of this\napplication the second--order correlation approximation is used. The\ninvestigation is of high interest in astrophysical context, too. Some\ncontributions to the mean electromotive are revealed which have not been\nconsidered so far, in particular contributions to the $\\alpha$--effect and\nrelated effects due to the gradient of the mean velocity. Their relevance for\ndynamo processes is discussed. In a forthcoming paper the results reported here\nwill be specified to the situation in the laboratory and partially compared\nwith experimental findings.",
