Phenylnaphthalene as a Heat Transfer Fluid for Concentrating Solar Power: High-Temperature Static Experiments
Concentrating solar power (CSP) may be an alternative to generating electricity from fossil fuels; however, greater thermodynamic efficiency is needed to improve the economics of CSP operation. One way of achieving improved efficiency is to operate the CSP loop at higher temperatures than the current maximum of about 400 C. ORNL has been investigating a synthetic polyaromatic oil for use in a trough type CSP collector, to temperatures up to 500 C. The oil was chosen because of its thermal stability and calculated low vapor and critical pressures. The oil has been synthesized using a Suzuki coupling mechanism and has been tested in static heating experiments. Analysis has been conducted on the oil after heating and suggests that there may be some isomerization taking place at 450 C, but the fluid appears to remain stable above that temperature. Tests were conducted over one week and further tests are planned to investigate stabilities after heating for months and in flow configurations. Thermochemical data and thermophysical predictions indicate that substituted polyaromatic hydrocarbons may be useful for applications that run at higher temperatures than possible with commercial fluids such as Therminol-VP1.

Childhood Bereavement and Parents’ Relationship With Children
It has long been recognized that childhood bereavement is a risk factor for depression in adulthood. Research also has consistently demonstrated that parental depression is linked to poor parent-child relationship quality. The current study examined whether bereavement in childhood increases likelihood of current depressive symptoms among parents and explored whether this vulnerability in the parent then alters the quality of the parent-child relationship. Archival data for a sample of 86 families (N=176 parents) are drawn from the Family & Kid Connection project led by Dr. Shelley Riggs. Instruments utilized include the Background Information Questionnaire, the Symptom Assessment-45 Questionnaire, and the Parenting Relationship Questionnaire. Using the Actor-Partner Interdependence Model, Multilevel Modeling procedures explored the hypothesis that parental depression mediates the association between parents’ childhood bereavement and their perception of the parent-child relationship. Results show a significant relationship between parental (actor) depressive symptoms and parent-child attachment, indicating the need for therapeutic interventions targeting the parent-child relationship, and not just parents, for parents suffering from depression.

Discovery of Very High Energy Gamma-Ray Emission from 1FGL J2001.1 4351 by MAGIC
We report the discovery of Very High Energy (VHE; >100 GeV) gamma-ray emission from the source 1FGL J2001.1+4351, (RA 20 01 13.5, dec 43 53 02.8, J2000), which is positionally consistent with the location of the flat spectrum radio source MG4 J200112+4352 (RA 20 01 12.9, dec 43 52 52.8, J2000). The VHE detection is based on a 1.5 hour-long observation performed on July 16th in stereoscopic mode with the two 17m diameter imaging Cherenkov telescopes on La Palma, Canary Islands, Spain. The preliminary analysis of the MAGIC data using the standard cuts optimized for soft energy spectra sources yields a detection of 125 gamma-rays above 90 GeV, corresponding to a pre-trail statistical significance of 7.6 standard deviations. The observed flux is estimated to be {approx}20% of the Crab nebula flux above 100 GeV. Earlier MAGIC observations indicated a substantially lower flux; hence indicating that the source is variable on a few days timescale.

Never Odd Or Even: Using Temporal Structures In Composing Music For Dance
This study engages the collaboration of dance and music, focusing primarily on experiences in the production of a large scale collaborative concert entitled Never Odd or Even. Famous historical collaborations offer archetypal collaborative models, the more unconventional of which are applied to the pieces of the concert. Issues and observations regarding cross-influence, project evolution, and application of the collaborative models are engaged to determine effective means of collaboration given different circumstances. The key focus of the study, the temporal relationship between music and dance, is explored in great detail to determine three models for relating time between music and dance. These temporal relationship models are applied to the pieces and evaluated on effectiveness and potential strengths when applied to dance.

All-Speed Methods and Long-Duration Time Integration for Incorporation into the 7-Equation Two-Phase Model
The numerical simulation of multiphase flows in Light Water (Nuclear) Reactors, LWRs, for normal, accident, and off-normal operation, and for operational optimization must cover a huge disparity of transient time durations, from milliseconds to years. In addition, our recent work has shown that the application of classical Riemann approaches, which pervade modern computational fluid dynamics (CFD), suffer numerical accuracy degradation, especially for compressible liquid flows. In this setting, all-speed or Mach uniform methods are need which can be accurately and efficiently integrated over a very large range of time scales. Thus we need a multi-time-scale integration approach to compliment our previously documented multi-spatial-scale approach to multiphase flow modeling [1]. This report briefly summarizes our efforts in these areas.

Vibration Model Validation for Linear Collider Detector Platforms
The ILC and CLIC reference designs incorporate reinforced-concrete platforms underneath the detectors so that the two detectors can each be moved onto and off of the beamline in a Push-Pull configuration. These platforms could potentially amplify ground vibrations, which would reduce luminosity. In this paper we compare vibration models to experimental data on reinforced concrete structures, estimate the impact on luminosity, and summarize implications for the design of a reinforced concrete platform for the ILC or CLIC detectors.

Countering Violent Extremism in the United States
In August 2011, the Obama Administration announced its counter-radicalization strategy. It is devised to address the forces that influence some people living in the United States to acquire and hold radical or extremist beliefs that may eventually compel them to commit terrorism. This is the first such strategy for the federal government, which calls this effort “combating violent extremism” (CVE). This report provides examples of recent Administration CVE activity and examines some of the risks and challenges evident in the SIP's three objectives. The report also diagrams and briefly discusses the “future activities and efforts” outlined in the SIP for each of these three objectives. A number of areas may call for oversight from Congress. These include the following: picking partners and establishing "rules of the road," intervention with at-risk individuals, identifying programs to assist grassroots CVE efforts, countering extremist ideas, the lack of a lead agency, and transparency.

The Domestic Terrorist Threat: Background and Issues for Congress
In the last decade, domestic terrorists-people who commit crimes within the homeland and draw inspiration from U.S.-based extremist ideologies and movements-have killed American citizens and damaged property across the country. Not all of these criminals have been prosecuted under terrorism statutes. This report discusses domestic terrorism's significance to policymakers per five topics: level of activity, use of nontraditional tactics, exploitation of the internet, decentralized nature of the threat, and prison radicalization. The report also discusses three areas that Congress may consider the federal role of combating such activities: the issue of definitions, adequacy of domestic terrorism intelligence collection efforts, and the value of community outreach driven efforts to quell terrorism related radicalization in the United States.

Safeguards-by-Design: Guidance for Independent Spent Fuel Dry Storage Installations (ISFSI)
This document summarizes the requirements and best practices for implementing international nuclear safeguards at independent spent fuel storage installations (ISFSIs), also known as Away-from- Reactor (AFR) storage facilities. These installations may provide wet or dry storage of spent fuel, although the safeguards guidance herein focuses on dry storage facilities. In principle, the safeguards guidance applies to both wet and dry storage. The reason for focusing on dry independent spent fuel storage installations is that this is one of the fastest growing nuclear installations worldwide. Independent spent fuel storage installations are typically outside of the safeguards nuclear material balance area (MBA) of the reactor. They may be located on the reactor site, but are generally considered by the International Atomic Energy Agency (IAEA) and the State Regulator/SSAC to be a separate facility. The need for this guidance is becoming increasingly urgent as more and more nuclear power plants move their spent fuel from resident spent fuel ponds to independent spent fuel storage installations. The safeguards requirements and best practices described herein are also relevant to the design and construction of regional independent spent fuel storage installations that nuclear power plant operators are starting to consider in the absence of a national …

Effects of Layer Double Hydroxide Nanoclays on the Toxicity of Copper to Daphnia Magna
Nanoparticles may affect secondary pollutants such as copper. Layer Double Hydroxides (LDH) are synthetically produced nanoparticles that adsorb copper via cation exchange. Pretreatment of copper test solutions with LDH nanoparticles followed by filtration removal of LDH nanoparticles demonstrated the smallest LDH aggregates removed the most copper toxicity. This was due to increased surface area for cation exchange relative to larger particle aggregates. Co-exposure tests of copper chloride and clay were run to determine if smaller clay particles increased copper uptake by D. magna. Coexposure treatments had lower LC50 values compared to the filtration tests, likely as a result of additive toxicity. LDH nanoclays do reduce copper toxicity in Daphnia magna and may serve as a remediation tool.

Requirements for Computer Based-Procedures for Nuclear Power Plant Field Operators Results from a Qualitative Study
Although computer-based procedures (CBPs) have been investigated as a way to enhance operator performance on procedural tasks in the nuclear industry for almost thirty years, they are not currently widely deployed at United States utilities. One of the barriers to the wide scale deployment of CBPs is the lack of operational experience with CBPs that could serve as a sound basis for justifying the use of CBPs for nuclear utilities. Utilities are hesitant to adopt CBPs because of concern over potential costs of implementation, and concern over regulatory approval. Regulators require a sound technical basis for the use of any procedure at the utilities; without operating experience to support the use CBPs, it is difficult to establish such a technical basis. In an effort to begin the process of developing a technical basis for CBPs, researchers at Idaho National Laboratory are partnering with industry to explore CBPs with the objective of defining requirements for CBPs and developing an industry-wide vision and path forward for the use of CBPs. This paper describes the results from a qualitative study aimed at defining requirements for CBPs to be used by field operators and maintenance technicians.

Final Report
The overall objective is to create robust artificial protein modules as scaffolds to control both (a) the conformation of novel cofactors incorporated into the modules thereby making the modules possess a desired functionality and (b) the organization of these functional modules into ordered macroscopic ensembles, whose macroscopic materials properties derive from the designed microscopic function of the modules. We focus on two specific types of cofactors for imparting functionality in this project; primarily nonlinear optical (NLO) chromophores designed to exhibit extraordinary molecular hyperpolarizabilities, as well as donor-bridge-acceptor cofactors designed to exhibit highly efficient, 'through-bonds' light-induced electron transfer (LIET) over nano-scale distances. The ensembles range from 2-D to 3-D, designed to possess the degree of orientational and positional order necessary to optimize their macroscopic response, the latter ranging from liquid-crystalline or glass-like to long-range periodic. Computational techniques, firmly based in statistical thermodynamics, are utilized for the design the artificial protein modules, based on robust {alpha}-helical bundle motifs, necessarily incorporating the desired conformation, location, and environment of the cofactor. Importantly, this design approach also includes optimization of the interactions between the modules to promote their organization into ordered macroscopic ensembles in 2-D and 3-D via either directed-assembly or self-assembly. When long-range periodic …

Oral History Interview with Frank Boffi, May 11, 2012
The National Museum of the Pacific War presents an oral interview with Frank Boffi. Boffi joined the Navy in September 1942 and received basic training in Newport. Boffi was assigned to the USS Bernadou (DD-153) as a machinist???s mate. He participated in the invasions of Sicily, Salerno, and Anzio. In June 1944 he was transferred to Norfolk to oversee the construction of the USS Hugh W. Hadley (DD-774). He joined the ship???s company, working in the engine room. He was badly burned during the kamikaze attack off of Okinawa, when damage to the ship sent hot steam blasting toward him as he escaped the engine room. A corpsman rescued Boffi, administered morphine. Boffi awoke two days later aboard the USS Solace (AH-5) and was transferred to Tinian, where he received the Purple Heart. He spent the next four months recovering and was discharged in November 1945. Boffi worked for the American Society of Safety Engineers until he retired at the age of 84.

A Study of the Technological, Instructional, and Motivational Factors Affecting Phr Certification Exam Outcomes
Although previous studies have considered the factors affecting other certification exam outcomes, they have not examined those that are related to performance on the Professional in Human Resources (PHR) exam. In response to that need, this study specifically investigates technology and training factors that affect self-efficacy and self-set goals, and through them, influence PHR certification exam results. The target population for the study consisted of recent examinees who had taken a formal PHR examination preparation class or used another form of exam preparation training. The survey results were analyzed using partial least squares modeling techniques, and mediation effects were then tested. The results demonstrated that PHR training self-efficacy affected PHR exam self-efficacy and self-set goals. These factors then had an impact on PHR exam scores. Also, the results of task-technology fit were indirectly related to PHR training self-efficacy through a multiple mediation model that included the instructional factor of time on task and the technology factor of perceived usefulness. Surprisingly, time spent on practice exam questions was found to be negatively related to PHR certification exam scores. Finally, instructional feedback indirectly affected outcomes through its positive relationship to self-set goals. The results of the research should help training professionals and …
