Magnetic interactions in sup 119 Sn substituted for Cu in antiferromagnetic and superconducting lamellar cuprates

Description: Moessbauer Spectroscopy (MS) studies of {sup 119}Sn were carried out in antiferromagnetic La{sub 2}(Cu{sub 0.99}Sn{sub 0.01})O{sub 4} (214) and in superconducting GdBa{sub 2}(Cu{sub 0.99}Sn{sub 0. 01}){sub 3}O{sub 7} (123). Non-magnetic Sn{sup 4+} substitutes for Cu if the right procedure for diffusing {sup 119}SnO{sub 2} in CuO is carried out. Studies performed in 214 show a large quadrupole splitting (QS) down to 120 K followed by an onset of a magnetic interaction reaching a saturation inter… more

Sequential probability ratio tests for reactor signal validation and sensor surveillance applications

Description: This paper examines the properties of sequential probability ratio tests (SPRT's) and the application of these tests to nuclear power reactor operation. Recently SPRT's have been applied to delayed-neutron (DN) signal data analysis using actual reactor data from the Experimental Breeder Reactor-II, which is operated by Argonne National Laboratory. The implementation of this research as part of an expert system is described. Mathematical properties of the SPRT are investigated, and theoretical r… more

[Regulation of terpene metabolism]. Annual progress report, March 15, 1989--March 14, 1990

Description: Terpenoid oils, resins, and waxes from plants are important renewable resources. The objective of this project is to understand the regulation of terpenoid metabolism using the monoterpenes (C{sub 10}) as a model. The pathways of monoterpene biosynthesis and catabolism have been established, and the relevant enzymes characterized. Developmental studies relating enzyme levels to terpene accumulation within the oil gland sites of synthesis, and work with bioregulators, indicate that monoterpene p… more
