Winter Fuels Report: Week Ending February 18, 1994

The Winter Fuels Report is intended to provide concise, timely information to the industry, the press, policymakers, consumers, analysts, and State and local governments on the following topics: distillate fuel oil net production, imports and stocks on a US level and for all Petroleum Administration for Defense Districts (PADD) and product supplied on a US level; propane net production, imports and stocks on a US level and for PADD`s I, II, and III; natural gas supply and disposition and underground storage for the US and consumption for all PADD`s; as well as selected National average prices; residential and wholesale pricing data for heating oil and propane for those States participating in the joint Energy Information Administration (EIA)/State Heating Oil and Propane Program; crude oil and petroleum price comparisons for the US and selected cities; and a 6--10 Day, 30-Day, and 90-Day outlook for temperature and precipitation and US total heating degree-days by city.

Heavy-ion-induced production and preseparation of short-livedisotopes for chemistry experiments (open access)

Heavy-ion-induced production and preseparation of short-livedisotopes for chemistry experiments

Physical separation of short-lived isotopes produced inheavy-ion-induced fusion reactions is a powerful and well know method andoften applied in investigations of the heaviest elements, called thetransactinides (Z>=104). By extracting these isotopes from a recoilseparator, they can be made available for transport to setups locatedoutside the heavily shielded irradiation position such as chemistrysetups. This physical preseparation technique overcomes many limitationscurrently faced in the chemical investigation of transactinides. Here wedescribe the basic principle using relatively short-lived isotopes of thelighter group 4 elements zirconium (Zr) and hafnium (Hf) that are used asanalogs of the lightest transactinide element, rutherfordium (Rf, element104). The Zr and Hf isotopes were produced at the LBNL 88-Inch Cyclotronusing a cocktail of 18O and 50Ti beams and the appropriate targets.Subsequently, the isotopes were physically separated in the BerkeleyGas-filled Separator (BGS) and guided to a Recoil Transfer Chamber (RTC)to transfer them to chemistry setups. The magnetic rigidities of thereaction products in low-pressure helium gas were measured and theiridentities determined with gamma-pectroscopy. Using preseparated isotopeshas the advantages of low background and beam plasma free environment forchemistry experiments. The new possibilities that open up for chemicalinvestigations of transactinide elements are descr ibed. The method canreadily be applied to homologous elements within other groups …

The Journey to Fielded BioInstrumentation (open access)

The Journey to Fielded BioInstrumentation

Over the last ten years, a team at Lawrence Livermore National Laboratory created fieldable instruments that performed identification/quantification via bioassays. These instruments have been based on molecular surface-recognition assays, such as immunoassays, and on nucleic-acid-based assays, such as the polymerase chain reaction. In 1996, we participated in the Joint Field Trials 3, employing both immunoassays as well as the polymerase chair reaction. In 1998, we participated in the Joint Field Trials 4, using only the real-time polymerase chain reaction, as implemented on a 10-chamber instrument. Our hand-held, real-time PCR instrument, known as HANAA has been commercialized as the Bioseeq{reg_sign}, by Smiths Detection. More recently, teams from LLNL have built and fielded an autonomous pathogen detection system (APDS).
