Live cultures of marine bacteria, previously collected from Antarctic waters, will be used in shipboard experiments to study feeding rates and transfer of nutrients in Antarctic protistan grazers. All remaining live cultures will be autoclaved before disposal.

NUREG/ CR–7010, Volume 1 documents the first phase of a multi-year program called CHRISTIFIRE (Cable Heat Release, Ignition, and Spread in Tray Installations during FIRE). The overall goal of the program is to quantify the burning characteristics of grouped electrical cables. The first phase of the program focuses on horizontal tray configurations. The experiments conducted range from micro-scale, in which very small (5 mg) samples of cable materials were burned in a calorimeter to determine their heat of combustion and other properties; to fullscale, in which horizontal, ladder-back trays loaded with varying amounts of cable were burned under a large oxygendepletion calorimeter. Other experiments include cone calorimetry, smoke and effluent characterization in a small test furnace, and intermediatescale calorimetry involving a single tray of cables underneath a bank of radiant panels. The results of the small-scale experiments are to serve as input data for fire models, while the results of the full-scale experiments are to serve as validation data for the models.
