  • When observed in their home cages, cats fed commercial tuna fish cat food were less active, vocalized less, and spent more time on the floor and more time eating than cats fed commercial beef cat food. There were no differences in response to human handling between the two groups. There were no differences in learning ability on a two-choice point maze or in reversal learning in the same maze between beef- and tuna-fed cats. The behavior of the groups differed in a 15-min open field test only in the number of toys contacted. Cats fed the tuna had elevated tissuemore » levels of mercury and selenium.« less
  • Because Ocean Thermal Energy Conversion (OTEC) operates at a low thermodynamic efficiency, heat exchangers represent a major portion of the overall cost of an OTEC power plant. For this reason, the commercial viability of OTEC depends on the design of efficient and inexpensive heat exchangers which have an operational life expectancy of 20 to 30 years and which can be maintained at a high level of efficiency by the use of effective biofouling control. Summarized here are the results of experiments conducted by the Center for Energy and Environment Research of the University of Puerto Rico to: determine the naturemore » of the biofilm which develops on heat exchanger surfaces exposed to running seawater, test the effectiveness of brush cleaning and chlorination in controlling biofouling on these surfaces and study the corrosion behavior of zinc protected aluminum alloys under OTEC conditions in an attempt to qualify them for use in low cost OTEC heat exchangers.« less
  • Successfully completed in 1982, the Tuna field in Australia's Gippsland basin was the most complex of the fields developed by Esso in that area. The commercial oil and gas reserves are contained in four sets of reservoirs in the Upper Cretaceous to Eocene Latrobe group sediments in a faulted and partly eroded anticlinal closure. Some of these reservoirs were not discovered until the development phase of drilling, causing significant changes to the initial development plan, notably the installation of multiple completions in 13 wells. The types of completions used were single, tandem, dual, and dual/tandem.
