Proper Motions of Faint UV-Bright Sources in the Sandage Two-color Survey of the Galactic Plane

Proper motions with values >10 mas/yr or <-10 mas/yr have been extracted from the USNO-B1.0 and Tycho II catalogues for all Lanning UV-bright sources identified in the Sandage Two-color Survey of the Galactic Plane and presented in Papers I-VI. Of the 572 sources examined, we find at least 213 which exhibit a significantly large proper motion. Based on the location of the sources in a reduced proper motion diagram, we demonstrate that about two thirds of the high proper motion sources are likely or very likely to be heretofore unidentified white dwarfs.Comment: 15 pages, to appear in Publications of the Astronomical Society of the Pacifi

Active Seismic frame synchronization

This ATM determines the probability of sync, false sync, and the probability of loosing sync for an 11 bit and 6 bit frame sync code. The number of bits/frame range from 1344 to 4032. The amount of data lost during loss of sync is also determined.prepared by H. Lanning

Mapping Our Future: The Impact of Gene Patents on Scientific Research and Health Care in the United States

In September, 2011, the Senate passed H.R. 1249, the Leahy-Smith America Invents Act (“AIA”), which President Barrack Obama signed into law on September 16th. The AIA is the largest transformation to U.S. patent law since 1952. While the new legislation implements numerous, positive changes to the U.S. patent system, it fails to address any of the concerns raised by gene patent critics over the past few decades. Gene patents should be categorized as patentable subject matter within the AIA, but under a separate patent category with specifically engineered regulations designed to promote scientific research and collaboration that will in turn foster quicker results in diagnostic technologies and treatments

Reactor physics calculation of BWR fuel bundles containing gadolinia

"January 1977.""YAEC-1126."Includes bibliographical references (pages 142-144)A technique for the calculation of the neutronic behavior of BWR fuel bundles has been developed and applied to a Vermont Yankee fuel bundle. The technique is based on a diffusion theory treatment of the bundle, with parameters for gadolinia bearing pins generated by transport theory, and converted to effective diffusion- theory values by means of blackness theory. The method has been used to examine the dependence of various bundle average parameters on control rod insertion history

An analysis of plutonium recycle fuel elements in San Onofre-1

"May 1974."Also issued as an Nucl. E. thesis by the first author, MIT, Dept. of Nuclear Engineering, 1974Includes bibliographical references (pages 167-171)A method has been developed to allow independent assessment of the use of plutonium recycle assemblies in operating reactors. This method utilizes Generalized Mixed Number Density (GMND) cross sections (based on Breen's Mixed Number Density cross sections) and the spectrum code LASER. LASER is modified to form LASER-M by adding ENDF/B-II thermal cross sections for the plutonium isotopes; adding edits to output G-aND cross sections, approximate microscopic removal and transport cross sections; and increasing LASERs compatibility with commonly used diffusion theory codes such as PDQ. Plutonium critical experiments for a number of lattices of 1.5 w/o and 6.6 w/o plutonium are analysed with LASER-M which is found to give better criticality agreement than LASER (without the ENDF/B-II plutonium cross sections) and other published data. Unit assembly power distributions are calculated for a uranium assembly and a constant and graded enrichment plutonium assembly both surrounded by uranium assemblies. The use of LASER-M with GMND cross sections is found to give excellent agreement with the published calculations of power distributions for the uranium assembly and good agreement for the plutonium assemblies. A quarter core depletion calculation of the San Onofre reactor containing four plutonium recycle demonstration assemblies is performed using the diffusion theory computer code PDQ-7. Use of PDQ-7 with GMND cross sections from LASER-M is shown to give excellent agreement with quasi experimental power distributions at cycle burnups of 0 MWD/MTM, 3342 MWD/MTM, and 6045 MWD/'MTM. Also, the calculated value of k-eff versus cycle burnup is determined to be in excellent agreement with the actual operating condition of k-eff = 1 .000
