The physiology of triploid fish: current knowledge and comparisons with diploid fish
This paper is aimed at underlining the limited knowledge available about the physiology of triploid fishes compared with diploids. Whereas many aspects (induction, detection, growth, resistance to diseases, etc.) in the production and rearing of triploid fishes have widely been developed and described in the literature, other numerous questions of ecophysiology remain in abeyance, and the study of triploid cells physiology is still in its infancy. Triploid fishes can be considered as models worthwhile for physiological investigations not only for the economical stake in relation to the development of triploid fishes rearing, but also for the cytological and molecular features of their tissues and organs. The functional implications of these features have been poorly studied although they are potential areas of applied and/or fundamental studies.
This paper presents a new structure of DRAM, using two-transistor cell. The most important advantages of this structure are: a) High speed read, write and refresh operation b) low data access latency c) low power consumption compared to other structures d) each write/refresh operation can be carried out just in one cycle and e) no need to special process and compatible with standard digital process.
