Waste-to-Energy Evaluation: U.S. Virgin Islands
This NREL technical report evaluates the environmental impact and fundamental economics of waste-to-energy (WTE) technology based on available data from commercially operating WTE facilities in the United States. In particular, it considers life-cycle impacts of WTE as compared to landfill disposal and various forms of electrical generation, as well as WTE impacts on source reduction or recycling programs. In addition, it evaluates the economics and potential environmental impact of WTE in the U.S. Virgin Islands (USVI) based on existing USVI waste stream characterization data, recycling challenges unique to the USVI, and the results of cost and environmental modeling of four municipal solid waste (MSW) management options, including landfill, refuse-derived fuel (RDF) production, recycling, and gassification plus RDF.

Water Adsorption on a-Fe2O3(0001) at Near Ambient Conditions
We have investigated hydroxylation and water adsorption on {alpha}-Fe{sub 2}O{sub 3}(0001) at water vapor pressures up to 2 Torr and temperatures ranging from 277 to 647 K (relative humidity (RH) {le} 34%) using ambient-pressure X-ray photoelectron spectroscopy (XPS). Hydroxylation occurs at the very low RH of 1 x 10{sup -7} % and precedes the adsorption of molecular water. With increasing RH, the OH coverage increases up to one monolayer (ML) without any distinct threshold pressure. Depth profiling measurements showed that hydroxylation occurs only at the topmost surface under our experimental conditions. The onset of molecular water adsorption varies from {approx}2 x 10{sup -5} to {approx} 4 x 10{sup -2} % RH depending on sample temperature and water vapor pressure. The coverage of water reaches 1 ML at {approx}15% RH and increases to 1.5 ML at 34% RH.

Where the Sidewalk Ends: Jets and Missing Energy Search Strategies for the 7 TeV LHC
This work explores the potential reach of the 7 TeV LHC to new colored states in the context of simplified models and addresses the issue of which search regions are necessary to cover an extensive set of event topologies and kinematic regimes. This article demonstrates that if searches are designed to focus on specific regions of phase space, then new physics may be missed if it lies in unexpected corners. Simple multiregion search strategies can be designed to cover all of kinematic possibilities. A set of benchmark models are created that cover the qualitatively different signatures and a benchmark multiregion search strategy is presented that covers these models.

Wilderness and Everyday Life.
I challenge the dualistic view of wilderness that has influenced wilderness philosophy, politics and experience in recent years. In its place, I offer an alternative vision that recognizes wilderness areas and working landscapes as complementary elements of a larger, inhabited landscape characterized by a heterogeneous mixture of human-land relational patterns representing various points along an urban-wilderness continuum. In chapters 2 through 4, I explore the philosophical, political and experiential implications of this wilderness-in-context vision. Experienced and understood as part of the landscape we call home, wilderness may engender, renew, and sustain an engaged and integrated wilderness practice involving regular contact with wilderness places, committed activism on behalf of wild lands and their inhabitants, and grounded reflection on the meaning and value of wilderness in our everyday lives.

A Wire Position Monitor System for the 1.3 FHZ Tesla-Style Cryomodule at the Fermilab New-Muon-Lab Accelerator
The first cryomodule for the beam test facility at the Fermilab New-Muon-Lab building is currently under RF commissioning. Among other diagnostics systems, the transverse position of the helium gas return pipe with the connected 1.3 GHz SRF accelerating cavities is measured along the {approx}15 m long module using a stretched-wire position monitoring system. An overview of the wire position monitor system technology is given, along with preliminary results taken at the initial module cooldown, and during further testing. As the measurement system offers a high resolution, we also discuss options for use as a vibration detector. An electron beam test facility, based on superconducting RF (SRF) TESLA-style cryomodules is currently under construction at the Fermilab New-Muon-Lab (NML) building. The first, so-called type III+, cryomodule (CM-1), equipped with eight 1.3 GHz nine-cell accelerating cavities was recently cooled down to 2 K, and is currently under RF conditioning. The transverse alignment of the cavity string within the cryomodule is crucial for minimizing transverse kick and beam break-up effects, generated by the high-order dipole modes of misaligned accelerating structures. An optimum alignment can only be guaranteed during the assembly of the cavity string, i.e. at room temperatures. The final position of the cavities …

World Trade Center Health Program: Potential Effects of Implementation Options
Correspondence issued by the Government Accountability Office with an abstract that begins "The James Zadroga 9/11 Health and Compensation Act of 2010 became law on January 2, 2011, and established a World Trade Center Health Program (WTCHP) to assume the functions of the World Trade Center (WTC) responder health programs beginning on July 1, 2011. From September 11, 2001, through fiscal year 2010, approximately $475 million in federal funds was made available for screening, monitoring, and treating WTC responders for illnesses and conditions related to the WTC disaster. These include asthma, persistent coughing, and other respiratory conditions and mental health conditions such as depression, anxiety, and post-traumatic stress disorder (PTSD). The three federal programs that provided screening, monitoring, and treatment services to responders prior to July 1, 2011, which we refer to here as the WTC responder health programs, were the New York City Fire Department's (FDNY) WTC Medical Monitoring and Treatment Program, the New York/New Jersey (NY/NJ) WTC Consortium, and the WTC National Responder Health Program. The WTCHP is administered by HHS and provides screening, monitoring, and treatment services through contracted clinical centers in the NYC area for responders in that area and through a nationwide network of providers …

The Z Charmoniumlike Mesons
A brief review of the experimental situation concerning the electrically charged charmoniumlike meson candidates, Z{sup -}, is presented. The Belle Collaboration reported peaks in the {psi}{prime}{pi}{sup -} and {chi}{sub c1}{pi}{sup -} invariant mass distributions in B {yields} {psi}{prime}{pi}{sup -}K and B {yields} {chi}{sub c1}{pi}{sup -}K, respectively. If these peaks are meson resonances, they would have a minimal quark substructure of c{bar c}d{bar u} and be unmistakeably exotic. However, even though the Belle signals have more than 5{sigma} statistical significance, the experimental situation remains uncertain in that none of these peaks have yet been confirmed by other experiments. An analysis by the BABAR Collaboration of B {yields} {psi}{prime}{pi}{sup -}K neither confirms nor contradicts the Belle claim for the Z(4430){sup -} {yields} {psi}{prime}{pi}{sup -}. In the BABAR analysis, B {yields} J/{psi}{pi}{sup -}K decays were also studied, and no evidence for Z(4430){sup -} {yields} J/{psi}{pi}{sup -} was found. In this paper, we review and compare Belle and BABAR results on searches for charged charmonium-like states.
