19-electron intermediates in the Ligand Substitution of CpW(CO)3with a Lewis Base (open access)

19-electron intermediates in the Ligand Substitution of CpW(CO)3with a Lewis Base

Odd electron species are important intermediates in organometallic chemistry, participating in a variety of catalytic and electron-transfer reactions which produce stable even-electron products. While electron deficient 17-electron (17e) radicals have been well characterized, the possible existence of short-lived 19-electron (19e) radicals has been a subject of continuing investigation. 19e radicals have been postulated as intermediates in the photochemical ligand substitution and disproportionation reactions of organometallic dimers containing a single metal-metal bond, yet the reactions of these intermediates on diffusion-limited time scales (ns-{micro}s) have never been directly observed. This study resolves the 19e dynamics in the ligand substitution of 17e radicals CpW(CO){sub 3}{sup {sm_bullet}} (Cp = C{sub 5}H{sub 5}) with the Lewis base P(OMe){sub 3}, providing the first complete description 19e reactivity.

45-Day safety screen results for single shell tank 241-AP-106, liquid grab samples, riser 1, 30{degrees} and 150{degrees} in conjunction with evaporator campaign 95-1

This is the 45-Day report for the fiscal year 1995 safety screening characterization of three liquid grab samples from single shell tank 241-AP-106. The required analyses are differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) and appearance (APPR). No analytes exceeded the notification limits, therefore, secondary analyses (RSST, cyanide, and hot persulfate-total organic carbon) were not required. Summary data tables 2, 3 and 4 present the appearance, DSC and TGA data, respectively. Total alpha analyses are not included in this report, because it is not required for liquid grab samples.

1978 USGS Geothermal Resource Assessment (open access)

1978 USGS Geothermal Resource Assessment

The author distinguishes between geothermal resource base, accessible geothermal resource base, geothermal resource, and geothermal reserve. Conditions for periodically updating the assessment of geothermal energy resources include: increased data from expanded exploration and drilling; development of improved and new technologies for exploration, evaluation, extraction, and use; rapid evolution of geothermal knowledge; and the increased role of geothermal energy in response to changing economic, social, political, and environmental conditions, particularly an increasing awareness of the limits to petroleum and natural gas resources. Accordingly, the U. S. Geological Survey (USGS) plans by the end of 1978 to update its 1975 assessment of the United States’ geothermal resource, with increased emphasis on several items. The USGS’s joint evaluations of geothermal resource-assessment techniques in the last year with the National Electric Agency of Italy (ENEL) under U. S. Energy Research and Development Agency sponsorship identified a number of problems, one of which was how to formulate geothermal recovery factors for systems producing by intergranular vaporization and by intergranular flow. The first formulation is fairly rigorous; the author solicits the reservoir engineering community’s help in improving the estimate of the second. 3 figs., 11 refs.

2010 Census: Data Collection Operations Were Generally Completed as Planned, but Long-standing Challenges Suggest Need for Fundamental Reforms (open access)

2010 Census: Data Collection Operations Were Generally Completed as Planned, but Long-standing Challenges Suggest Need for Fundamental Reforms

A letter report issued by the Government Accountability Office with an abstract that begins "Although the U.S. Census Bureau (Bureau) generally completed the field data collection phase of the 2010 Census consistent with its operational plans, at $13 billion, 2010 was the costliest census in the nation's history. Moving forward, it will be important to both refine existing operations as well as to reexamine the fundamental approach to the census to better address long-standing issues such as securing participation and escalating costs. As requested, this report reviews (1) the conduct of nonresponse follow-up (NRFU), where enumerators collect data from households that did not return their census forms, (2) the implementation of other field operations critical to a complete count, and (3) potential reexamination areas that could help produce a more cost-effective 2020 Census. The report is based on GAO's analysis of Bureau data and documents, surveys of local census office managers, and field observations."

2010 Census: Follow-up Should Reduce Coverage Errors, but Effects on Demographic Groups Need to Be Determined (open access)

2010 Census: Follow-up Should Reduce Coverage Errors, but Effects on Demographic Groups Need to Be Determined

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Census Bureau (Bureau) puts forth tremendous effort to conduct a complete and accurate count of the nation's population and housing; yet some degree of error in the form of persons missed, duplicated, or counted in the wrong place is inevitable due to the complexity in counting a large and diverse population. The Bureau designed two operations, Coverage Follow-up (CFU) and Field Verification (FV), to reduce certain types of counting, or coverage, errors in the 2010 Census. GAO was asked to assess (1) the extent to which the Bureau completed CFU and FV on schedule and within estimated cost and (2) the implications of their key design elements for improving coverage. GAO reviewed Bureau evaluations, planning, and other documents on CFU and FV, and prior GAO work, and interviewed Bureau officials."

2010 Census: Key Efforts to Include Hard-to-Count Populations Went Generally as Planned; Improvements Could Make the Efforts More Effective for Next Census

A letter report issued by the Government Accountability Office with an abstract that begins "To overcome the long-standing challenge of enumerating hard-to-count (HTC) groups such as minorities and renters, the U.S. Census Bureau (Bureau), used outreach programs, such as paid advertising, and partnered with thousands of organizations to enlist their support for the census. The Bureau also conducted Service-Based Enumeration (SBE), which was designed to count people who frequent soup kitchens or other service providers, and the Be Counted/Questionnaire Assistance Center (QAC) program, designed to count individuals who believed the census had missed them. As requested, GAO assessed how the design of these efforts compared to 2000 and the extent to which they were implemented as planned. GAO reviewed Bureau budget, planning, operational, and evaluation documents; observed enumeration efforts in 12 HTC areas; surveyed local census office managers; and interviewed Bureau officials."

2D Optical Streaking for Ultra-Short Electron Beam Diagnostics (open access)

2D Optical Streaking for Ultra-Short Electron Beam Diagnostics

We propose a novel approach to measure short electron bunch profiles at micrometer level. Low energy electrons generated during beam-gas ionization are simultaneously modulated by the transverse electric field of a circularly-polarized laser, and then they are collected at a downstream screen where the angular modulation is converted to a circular shape. The longitudinal bunch profile is simply represented by the angular distribution of the electrons on the screen. We only need to know the laser wavelength for calibration and there is no phase synchronization problem. Meanwhile the required laser power is also relatively low in this setup. Some simulations examples and experimental consideration of this method are discussed. At Linac Coherent Light Source (LCLS), an S-band RF transverse deflector (TCAV) is used to measure the bunch length with a resolution 10 femtosecond (fs) rms. An X-band deflector (wavelength 2.6cm) is proposed recently to improve the resolution. However, at the low charge operation mode (20pC), the pulse length can be as short as fs. It is very challenging to measure femtosecond and sub-femtosecond level bunch length. One of the methods is switching from RF to {mu}m level wavelength laser to deflect the bunch. A powerful laser ({approx}10s GW) is required …
