TT Arietis - Observations of a Cataclysmic Variable Star with the MOST Space Telescope
We measured the photometric flux of the cataclysmic variable TT Arietis
(BD+14 341) using the MOST space telescope. Periodic oscillations of the flux
reveal the orbital period as well as other features of this binary system. We
applied a Discrete Fourier Transform (DFT) on a reduced dataset to retrieve the
frequencies of TT Arietis. The analysis of the system revealed a photometric
period of 3.19 hours. Though the MOST data has a high cadence of 52.8 seconds,
a fine structure of the accretion disk is not obvious.Comment: 3 pages, 1 figure, JENAM 2008 proceeding

Development of an in vitro culture method for cells and tissues from the zebra mussel (Dreissena polymorpha)
Despite the successful transfer of mammalian in vitro techniques for use with fish and other vertebrates, little progress has been made in the area of invertebrate tissue culture. This paper describes the development of an in vitro technique for the culture of both cells in suspension and tissue explants from the gill, digestive gland and mantle of the zebra mussel (Dreissena polymorpha) and their successful maintenance in culture for up to 14 days. Cell suspensions from the gills and digestive gland were the most successful technique developed with viability >80% maintained for up to 8 days in culture, suitable for use in short term toxicity tests. Tissue explants from the mantle were also maintained in culture for up to 14 days. This paper describes the challenges involved in the development of a novel in vitro culture technique for aquatic invertebrates
