EXTRACTION OF NEPTUNIUM FROM ACIDIC SOLUTIONS BY ORGANIC NITROGEN AND PHOSPHORUS COMPOUNDS

Description: Neptunium distribution coefficients from acid nitrate, chloride, and sulfate solutions by several organic nitiogen and phosphorus compounds were measured as functions of several extraction variables, including neptunium valence, acid and salt concentration, and reagent concentration. Extractability by all the reagents varied in the order Np(IV)> Np(VI)>> Np(V). Except for primary amines, all reagents extracted Np(IV) much more strongly from nitrate than sulfate solutions. Among organonitrogen c… more

Notes on Luminosity Variation at ISABELLE

Description: In the present ISABELLE design, the luminosity at each insertion will be the same, unless special efforts are taken to get a low-..beta.. insertion or reduced crossing angle. These can only change the luminosity by factors of 2 to 4 from insertion to insertion. An estimation of the range of desired luminosities is given.

Low Temperature Thermoluminescence of Gamma Irradiated Potassium Dihydrogen Phosphate

Description: Thermoluminescence in potassium dihydrogen phosphate (KDP) induced by Co/ sup 60/ gamma irradiation at liquid nitrogen temperature (-198 deg C) was investigated. Glow curves in the temperature range --196 to 0 deg C were measured for a series of gamma exposure dosages ranging from 10/sup 4/ roentgen to 5 x 10/sup 6/ roentgen. The heating rate used for glow curve measurements was 12 deg C per minute. Twice recrystallized Mallinckrodt reagent grade potassium dihydrogen phosphate, with a grain siz… more

INFLUENCE OF RADIATION FROM AN UNSHIELDED REACTOR ON A NATURAL MICROFLORA

Description: The soil microflora and its respiratory activity were measured in soil cores collected at different distances from an unshielded reactor. No direct correlation was found between dose received and microbial counts or respiration. Indication of a correlation between dose and microbial respiration was obtained after eliminating the overriding influence of moisture. Radiation probably affected the soil microflora through damage to the phanerogam vegetation rather than directly. This preliminary stu… more

Tokamak Fusion Test Reactor neutral beam injection system vacuum chamber

Description: Most of the components of the Neutral Beam Lines of the Tokamak Fusion Test Reactor (TFTR) will be enclosed in a 50 cubic meter box-shaped vacuum chamber. The chamber will have a number of unorthodox features to accomodate both neutral beam and TFTR requirements. The design constraints, and the resulting chamber design, are presented.

Ion-beam inertial fusion: the requirements posed by target and deposition physics

Description: The demonstration of ICF scientific feasibility requires success in target design, driver development and target fabrication. Since these are interrelated, we present here some results of ion beam target studies and relate them to parameters of interest to ion accelerators. Ion deposition physics have long been a well known subject apart from high beam currents. Recent NRL experiments at up to 250 kA/cm/sup 2/ ions confirm the classical deposition physics now at current densities which are comp… more

Delay line proportional chambers for the Fermilab external muon identifier

Description: Thirty-nine one meter square proportional chambers with delay line readout were constructed for the external muon identifier of the Fermilab 15 foot bubble chamber. They provide X,Y,U(45/sup 0/) and T (avalanche time) information using a single wire plane, etched strip cathodes and nine amplifiers. They have a time resolution of +-27ns, single particle spatial resolution of +-2 to +-3mm and double particle resolution of approximately 2/sup 1///sub 2/ to 4cm. The energy accessible to each wire i… more

X-ray lines as a density diagnostic in DT plasmas near 100x solid density

Description: The use of electron impact broadened resonance lines to diagnose near-term high density diagnostics is discussed. In particular, the question of how to choose seed and pusher materials to have discernible broadening effects while maintaining line visibility is discussed.

Surface Coal Mining: Information on Clean Water Act Section 404 Permit Reviews under Enhanced Coordination Procedures in Appalachia, Focusing on West Virginia

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "In 2009, West Virginia accounted for about 43 percent of the surface coal mining production in Appalachia. Surface coal mining in the mountainous areas of Appalachia--a process often referred to as mountaintop mining--has generated opposition in recent years because of its impact on landscapes, streams, ecosystems, and communities. In mountaintop mining, before the underlying coal can be extracted, the l… more

State Department: Evacuation Planning and Preparations for Overseas Posts Can Be Improved

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Since 1988, the Department of State (State) has ordered over 270 evacuations from overseas posts due to civil strife, terrorist incidents, natural disasters, conventional war threats, and disease outbreaks. To prepare for evacuation, overseas posts rely on a variety of guidance, plans, and training, such as Emergency Action Plans (EAP). GAO was asked to assess State's (1) guidance and plans to prepare f… more

Commodity Futures Trading Commission: Trends in Energy Derivatives Markets Raise Questions about CFTC's Oversight

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Prices for four energy commodities--crude oil, heating oil, unleaded gasoline, and natural gas--have risen substantially since 2002. Some observers believe that higher energy prices are the result of changes in supply and demand. Others believe that increased futures trading activity has also contributed to higher prices. This report, conducted under the Comptroller General of the United States' authori… more

THE ORIGIN OF LIFE ON EARTH AND ELSEWHERE. II

Description: The synthesis of relatively complex organic molecules by ionizing and radical mechanisms (induced by high energy radiations, ultraviolet and electric discharge) from methane, ammonia, water, and hydrogen is described, both theoretically and experimentally. It is shown that the molecules which tend to be formed under such random conditions are the very ones which today are the common building blocks in the biological reconstruction of organic material. Such molecules are the amino acids, the sim… more
