    Notes: Abstract The salinity tolerances of four species of small fishes native to the Murray-Darling river system were measured. Slow acclimation LD50s were 43.7 ± 1.7 g L−1 for Craterocephalus stercusmuscarum Gunther, 38.0 ± 1.1 g L−1 for Hypseleotris klunzingeri (Ogilby), 58.7 ± 0.9 g L−1 for Retropinna semoni (Weber), and 29.8 ± 0.7 g L−1 for Melanotaenia splendida (Castelnau). The salinity tolerance of M. splendida was also measured by direct transfer, providing an estimated LD50 (infinite exposure time) of 20.8 g L−1, ∼ 70% of the slow acclimation value. Results suggest that at least adults of the species studied are under no threat from present or foreseeable salinities in the Murray River.

    Power transmission by laser beam from lunar-synchronous satellites to a lunar rover (1992)

    Publication Date: 2011-08-24
    Description: This study addresses the possibility of beaming laser power from synchronous lunar orbits (L1 and L2 LaGrange points) to a manned long-range lunar rover. The rover and two versions of a satellite system (one powered by a nuclear reactor; the other by photovoltaics) are described in terms of their masses, geometry, power needs, mission and technological capabilities. Laser beam power is generated by a laser diode array in the satellite and converted to 30 kW of electrical power at the rover. Present technological capabilities, with some extrapolation to near future capabilities, are used in the descriptions. The advantages of the two satellite/rover systems over other such systems and over rovers with on-board power are discussed along with the possibility of enabling other missions.
