Presidential Helicopter Acquisition: Effort Delayed as DOD Adopts New Approach to Balance Requirements, Costs, and Schedule (open access)

Presidential Helicopter Acquisition: Effort Delayed as DOD Adopts New Approach to Balance Requirements, Costs, and Schedule

Correspondence issued by the Government Accountability Office with an abstract that begins "The formal start of the VXX presidential helicopter program has been delayed, as finding an acceptable solution has proved elusive. Last year, we reported that the VXX effort was in the earliest stages of development--still developing a business case to launch product development. At that time, an AOA—required for a Milestone A decision initiating the program—was nearing completion and a Milestone A decision was expected to occur sometime in fiscal year 2011. In March 2011 the Navy sent DOD its VXX AOA study, which Navy officials stated was done in compliance with DOD-provided guidance. DOD did not, however, approve the study as it did not find that the study provided a cost effective solution. Rather, OSD and the Navy subsequently decided to update the analysis of alternatives using an acquisition strategy that might result in a more timely and affordable program using additional guidance provided by OSD in December 2011. That guidance reflects insights on requirements gained in the last year and expectations of using a streamlined acquisition approach proposed by the Navy. This has delayed the VXX program’s entry into development. Navy officials expect that this new …

Afghanistan: Improvements Needed to Strengthen Management of U.S. Civilian Presence (open access)

Afghanistan: Improvements Needed to Strengthen Management of U.S. Civilian Presence

A letter report issued by the Government Accountability Office with an abstract that begins "U.S. agencies under Chief of Mission authority and the Department of Defense (DOD) have reported expanding their civilian presence in Afghanistan and took steps to improve their ability to track that presence. Since January 2009, U.S. agencies under Chief of Mission authority more than tripled their civilian presence from 320 to 1,142. However, although State could report total Chief of Mission numbers by agency, in mid-2011 GAO identified discrepancies in State’s data system used to capture more-detailed staffing information such as location and position type. State began taking steps in the fall of 2011 to improve the reliability of its data system. Also, DOD reported expanding its overall civilian presence from 394 civilians in January 2009 to 2,929 in December 2011 to help assist U.S. efforts in Afghanistan. The extent to which DOD’s data is reliable is unknown due to omissions and double counting, among other things. In a 2009 report, GAO noted similar data issues and recommended DOD improve data concerning deployed civilians. DOD concurred with the recommendation and expects the issues will be addressed by a new tracking system to be completed in fiscal …

VA Health Care: Methodology for Estimating and Process for Tracking Savings Need Improvement (open access)

VA Health Care: Methodology for Estimating and Process for Tracking Savings Need Improvement

A letter report issued by the Government Accountability Office with an abstract that begins "GAO found that VA’s estimated savings from two of its six operational improvements lacked analytic support and estimated savings from another were flawed. Without a sound methodology for estimating these savings, VA runs the risk of not achieving them. Furthermore, due in part to flaws GAO identified with another operational improvement—reducing acquisition costs—VA decided to revise it. Because this effort was still in progress, GAO could not evaluate VA’s estimated savings and process for tracking actual savings from this operational improvement. In addition, GAO found that VA lacks a process for tracking actual savings for one operational improvement and its processes may overstate results for two others. Without an accurate process for tracking these savings, VA will be unable to determine whether it has realized the estimated savings reflected in the President’s budget request for fiscal years 2012 and 2013."

EFFECTIVE POROSITY IMPLIES EFFECTIVE BULK DENSITY IN SORBING SOLUTE TRANSPORT (open access)

EFFECTIVE POROSITY IMPLIES EFFECTIVE BULK DENSITY IN SORBING SOLUTE TRANSPORT

The concept of an effective porosity is widely used in solute transport modeling to account for the presence of a fraction of the medium that effectively does not influence solute migration, apart from taking up space. This non-participating volume or ineffective porosity plays the same role as the gas phase in single-phase liquid unsaturated transport: it increases pore velocity, which is useful towards reproducing observed solute travel times. The prevalent use of the effective porosity concept is reflected by its prominent inclusion in popular texts, e.g., de Marsily (1986), Fetter (1988, 1993) and Zheng and Bennett (2002). The purpose of this commentary is to point out that proper application of the concept for sorbing solutes requires more than simply reducing porosity while leaving other material properties unchanged. More specifically, effective porosity implies the corresponding need for an effective bulk density in a conventional single-porosity model. The reason is that the designated non-participating volume is composed of both solid and fluid phases, both of which must be neglected for consistency. Said another way, if solute does not enter the ineffective porosity then it also cannot contact the adjoining solid. Conceptually neglecting the fluid portion of the non-participating volume leads to a …

2011 Annual Ecological Survey: Pacific Northwest National Laboratory Site (open access)

2011 Annual Ecological Survey: Pacific Northwest National Laboratory Site

The U.S. Department of Energy (DOE) Pacific Northwest Site Office (PNSO) oversees and manages the DOE contract for the Pacific Northwest National Laboratory (PNNL), a DOE Office of Science multi-program laboratory located in Richland, Washington. PNSO is responsible for ensuring that all activities conducted on the PNNL site comply with applicable laws, policies, and DOE Orders. The DOE Pacific Northwest Site Office Cultural and Biological Resources Management Plan (DOE/PNSO 2008) addresses the requirement for annual surveys and monitoring for species of concern and to identify and map invasive species. In addition to the requirement for an annual survey, proposed project activities must be reviewed to assess any potential environmental consequences of conducting the project. The assessment process requires a thorough understanding of the resources present, the potential impacts of a proposed action to those resources, and the ultimate consequences of those actions. The PNNL site is situated on the southeastern corner of the DOE Hanford Site, located at the north end of the city of Richland in south-central Washington. The site is bordered on the east by the Columbia River, on the west by Stevens Drive, and on the north by the Hanford Site 300 Area (Figure 1). The environmental …

Nevada National Security Site 2011 Data Report: Groundwater Monitoring Program Area 5 Radioactive Waste Management Site (open access)

Nevada National Security Site 2011 Data Report: Groundwater Monitoring Program Area 5 Radioactive Waste Management Site

This report is a compilation of the groundwater sampling results from the Area 5 Radioactive Waste Management Site (RWMS). The data have been collected since 1993 and include calendar year 2011 results. During 2011, groundwater samples were collected and static water levels were measured at the three pilot wells surrounding the Area 5 RWMS. Samples were collected at UE5PW-1 on March 8, August 2, August 24, and October 19, 2011; at UE5PW-2 on March 8, August 2, August 23, and October 19, 2011; and at UE5PW-3 on March 8, August 2, August 23, and October 19, 2011. Static water levels were measured at each of the three pilot wells on March 1, June 7, August 1, and October 17, 2011. Groundwater samples were analyzed for the following indicators of contamination: pH, specific conductance, total organic carbon, total organic halides, and tritium. Indicators of general water chemistry (cations and anions) were also measured. Initial total organic carbon and total organic halides results for samples collected in August 2011 were above previous measurements and, in some cases, above the established investigation limits. However, after field sample pumps and tubing were disinfected with Clorox solution, the results returned to normal levels. Final results …

Structural and Kinetic Studies of Novel Cytochrome P450 Small-Alkane Hydroxylases (open access)

Structural and Kinetic Studies of Novel Cytochrome P450 Small-Alkane Hydroxylases

The goals of this project are to investigate (1) the kinetics and stabilities of engineered cytochrome P450 (P450) small alkane hydroxylases and their evolutionary intermediates, (2) the structural basis for catalytic proficiency on small alkanes of these engineered P450s, and (3) the changes in redox control resulting from protein engineering. To reach these goals, we have established new methods for determining the kinetics and stabilities of multicomponent P450s such as CYP153A6. Using these, we were able to determine that CYP153A6 is proficient for hydroxylation of alkanes as small as ethane, an activity that has never been observed previously in any natural P450. To elucidate the structures of the engineered P450s, we obtained x-ray diffraction data for two variants in the P450PMO (propane monooxygenase) lineage and a preliminary structure for the most evolved variant. This structure shows changes in the substrate binding regions of the enzyme and a reduction in active site volume that are consistent with the observed changes in substrate specificity from fatty acids in the native enzyme to small alkanes in P450PMO. We also constructed semi-rational designed libraries mutating only residues in the enzyme active site that in one round of mutagenesis and screening produced variants that achieved …

HHFW Power Flow Along Magnetic Field Lines In The Scrape-off Layer of NSTX (open access)

HHFW Power Flow Along Magnetic Field Lines In The Scrape-off Layer of NSTX

A significant fraction of high-harmonic fast-wave (HHFW) power applied to NSTX can be lost to the scrape-off layer (SOL) and deposited in bright and hot spirals on the divertor rather than in the core plasma. We show that the HHFW power flows to these spirals along magnetic field lines passing through the SOL in front of the antenna, implying that the HHFW power couples across the entire width of the SOL rather than mostly at the antenna face. This result will help guide future efforts to understand and minimize these edge losses in order to maximize fast wave heating and current drive.

Energy Saving Glass Lamination via Selective Radio Frequency Heating (open access)

Energy Saving Glass Lamination via Selective Radio Frequency Heating

This project focused on advancing radio-frequency (RF) lamination technology closer to commercial implementation, in order to reduce the energy intensity of glass lamination by up to 90%. Lamination comprises a wide range of products including autoglass, architectural safety and innovative design glass, transparent armor (e.g. bullet proof glass), smart glass, mirrors, and encapsulation of photovoltaics. Lamination is also the fastest growing segment of glass manufacturing, with photovoltaics, architectural needs, and an anticipated transition to laminated side windows in vehicles. The state-of-the-art for glass lamination is to use autoclaves, which apply heat and uniform gas pressure to bond the laminates over the course of 1 to 18 hours. Laminates consist of layers of glass or other materials bonded with vinyl or urethane interlayers. In autoclaving, significant heat energy is lost heating the chamber, pressurized air, glass racks, and the glass. In RF lamination, the heat is generated directly in the vinyl interlayer, causing it to heat and melt quickly, in just 1 to 10 minutes, without significantly heating the glass or the equipment. The main purpose of this project was to provide evidence that low energy, rapid RF lamination quality met the same standards as conventionally autoclaved windows. The development of …

Analysis of 2011 Meteorological Data from the Knolls Atomic Power Laboratory and Kesselring Site Operations Facilities (open access)

Analysis of 2011 Meteorological Data from the Knolls Atomic Power Laboratory and Kesselring Site Operations Facilities

Both the Knolls Atomic Power Laboratory (KAPL) in Schenectady, NY and the Kesselring Site Operations (KSO) facility near Ballston Spa, NY are required to estimate the effects of hypothetical emissions of radiological material from their respective facilities by the US Environmental Protection Agency (EPA), which regulates these facilities. An atmospheric dispersion model known as CAP88, which was developed and approved by the EPA for such purposes, is used by KAPL and KSO to meet this requirement. CAP88 calculations over a given time period are based on statistical data on the meteorological conditions for that period. Both KAPL and KSO have on-site meteorological towers which take atmospheric measurements at a frequency ideal for EPA regulatory model input. However, an independent analysis and processing of the meteorological data from each tower is required to derive a data set appropriate for use in the CAP88 model. The National Atmospheric Release Advisory Center (NARAC) was contracted by KAPL to process the on-site data for the calendar year 2011. The purpose of this document is to: (1) summarize the procedures used in the preparation/analysis of the 2011 meteorological data; and (2) document adherence of these procedures to the guidance set forth in 'Meteorological Monitoring Guidance …

Final Report: Detection and Characterization of Underground Facilities by Stochastic Inversion and Modeling of Data from the New Generation of Synthetic Aperture Satellites (open access)

Final Report: Detection and Characterization of Underground Facilities by Stochastic Inversion and Modeling of Data from the New Generation of Synthetic Aperture Satellites

Many clandestine development and production activities can be conducted underground to evade surveillance. The purpose of the study reported here was to develop a technique to detect underground facilities by broad-area search and then to characterize the facilities by inversion of the collected data. This would enable constraints to be placed on the types of activities that would be feasible at each underground site, providing a basis the design of targeted surveillance and analysis for more complete characterization. Excavation of underground cavities causes deformation in the host material and overburden that produces displacements at the ground surface. Such displacements are often measurable by a variety of surveying or geodetic techniques. One measurement technique, Interferometric Synthetic Aperture Radar (InSAR), uses data from satellite-borne (or airborne) synthetic aperture radars (SARs) and so is ideal for detecting and measuring surface displacements in denied access regions. Depending on the radar frequency and the acquisition mode and the surface conditions, displacement maps derived from SAR interferograms can provide millimeter- to centimeter-level measurement accuracy on regional and local scales at spatial resolution of {approx}1-10 m. Relatively low-resolution ({approx}20 m, say) maps covering large regions can be used for broad-area detection, while finer resolutions ({approx}1 m) can …

Oral History Interview with Robert D. Molleston, February 27, 2012 transcript

Oral History Interview with Robert D. Molleston, February 27, 2012

The National Museum of the Pacific War presents an oral interview with Robert D. Molleston. Molleston joined the Navy in 1943 and trained at Farragut, Idaho. From there he went to radio school and aerial gunnery school before he was assigned to Air Group 6 and shipped to Hawaii aboard the USS General E.T. Collins (AP-147). In March, 1945, Molleston and his unit boarded the USS Hancock (CV-19) at Ulithi. Molleston reads from his diary he kept in his flight log book (May through June, 1945). It describes actions and raids against Okinawa and the Japanese home islands as well as kamikaze attacks on the US fleet. In August, the plane Molleston was in was shot down. He was rescued by the USS Harrison (DD-573). Molleston reads a story he wrote about the experience. He was wounded in the leg and spent a lot of time in hospitals right after the war. Molleston also reads from his diary regarding his experience in 2009 going on an Honor Flight to Washington, DC to dsee the National World War II Memorial.
