Due to the very small relative volatility difference between propane and propylene, current propane/propylene separation by distillation requires very tall distillation towers (150-250 theoretical plates) and large reflux ratios (up to 15), which is considered to be the most energy consuming large-scale separation process. Adsorptive separation processes are widely considered to be more energy-efficient alternatives to distillation. However, slow diffusion kinetics/mass transport rate through the adsorbent bed often limits the performance of such processes, so further improvements are possible if intra-particle mass transfer rates can be improved. Rive Technology, Inc. is developing and commercializing its proprietary mesoporous zeolite technology for catalysis and separation. With well-controlled intracrystalline mesoporosity, diffusion kinetics through such mesoporous zeolite based catalysts is much improved relative to conventional zeolites, leading to significantly better product selectivity. This 'proof-of-principle' project (DE-EE0003470) is intended to demonstrate that Rive mesoporous zeolite technology can be extended and applied in adsorptive propane/propylene separation and lead to significant energy saving compared to the current distillation process. In this project, the mesoporous zeolite Y synthesis technology was successfully extended to X and A zeolites that are more relevant to adsorbent applications. Mesoporosity was introduced to zeolite X and A for the first time while maintaining …

Key issues include reform efforts initiated after anti-government demonstrations in early 2011 and amid the regional tumult of the "Arab Spring"; terrorism and related security issues; human rights; national reconciliation following the "dark decade" of the 1990s Islamist insurgency; and activism in ethnic Berber areas.

California's electricity markets are moving toward dynamic pricing models, such as real-time pricing, within the next few years, which could have a significant impact on an industrial facility's cost of energy use during the times of peak use. Adequate controls and automated systems that provide industrial facility managers real-time energy use and cost information are necessary for successful implementation of a comprehensive electricity strategy; however, little is known about the current control capacity of California industries. To address this gap, Lawrence Berkeley National Laboratory, in close collaboration with California industrial trade associations, conducted a survey to determine the current state of controls technologies in California industries. This,study identifies sectors that have the technical capability to implement Demand Response (DR) and Automated Demand Response (Auto-DR). In an effort to assist policy makers and industry in meeting the challenges of real-time pricing, facility operational and organizational factors were taken into consideration to generate recommendations on which sectors Demand Response efforts should be focused. Analysis of the survey responses showed that while the vast majority of industrial facilities have semi- or fully automated control systems, participation in Demand Response programs is still low due to perceived barriers. The results also showed that the …

During this funding period, we have developed two breakthrough techniques. The first is stimulated Raman scattering microscopy, providing label-free chemical contrast for chemical and biomedical imaging based on vibrational spectroscopy. Spontaneous Raman microscopy provides specific vibrational signatures of chemical bonds, but is often hindered by low sensitivity. We developed a three-dimensional multiphoton vibrational imaging technique based on stimulated Raman scattering (SRS). The sensitivity of SRS imaging is significantly greater than that of spontaneous Raman microscopy, which is achieved by implementing high-frequency (megahertz) phase-sensitive detection. SRS microscopy has a major advantage over previous coherent Raman techniques in that it offers background-free and readily interpretable chemical contrast. We demonstrated a variety of biomedical applications, such as differentiating distributions of omega-3 fatty acids and saturated lipids in living cells, imaging of brain and skin tissues based on intrinsic lipid contrast, and monitoring drug delivery through the epidermis. This technology offers exciting prospect for medical imaging. The second technology we developed is stimulated emission microscopy. Many chromophores, such as haemoglobin and cytochromes, absorb but have undetectable fluorescence because the spontaneous emission is dominated by their fast non-radiative decay. Yet the detection of their absorption is difficult under a microscope. We use stimulated emission, which …

A letter report issued by the Government Accountability Office with an abstract that begins "As of January 2012, GAO identified seven alternative models for compensating NRSROs (see table below). These models generally were designed to address the conflict of interest in the issuer-pays model, better align the NRSROs’ interest with users of ratings, or improve incentives NRSROs have to produce reliable and high-quality ratings. However, the amount of detail currently available for each model varies and none has been implemented. According to some of the authors of the models, there is little incentive to continue developing these models because it appears unlikely they will receive attention from regulators or legislators. For example, these authors noted that SEC had not reached out to them to further discuss these models as part of its ongoing study of alternative compensation models for credit rating agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "Tier 1 hybrid capital instruments, particularly trust preferred securities, have been heavily used by bank holding companies because of their financial advantages, but they are not as effective in absorbing losses as traditional forms of Tier 1 capital, such as common equity. As of December 31, 2010, almost two-thirds of all top-level bank holding companies that were subject to capital requirements included hybrid instruments in their Tier 1 capital, for a total value of $157 billion. Hybrid instruments such as trust preferred securities have offered institutions the benefit of lower-cost capital, largely because of their debt-related features—including tax-deductible dividends. These instruments also are accessible to a broader range of potential investors. However, trust preferred securities do not absorb losses like other Tier 1 instruments because of their obligation to repay principal and dividends. Trust preferred securities may provide limited financial flexibility in times of stress, but they may also hinder efforts to recapitalize troubled banking institutions."

The huge earthquake and tsunami that struck Japan's Fukushima Daiichi nuclear power station on March 11, 2011, knocked out backup power systems that were needed to cool the reactors at the plant, causing three of them to undergo fuel melting, hydrogen explosions, and radioactive releases. Radioactive contamination from the Fukushima plant forced the evacuation of communities up to 25 miles away and affected up to 100,000 residents, although it did not cause any immediate deaths. Studies of the Fukushima disaster have identified design changes, response actions, and other safety improvements that could have reduced or eliminated the amount of radioactivity released from the plant. As a result, Fukushima has prompted a reexamination of nuclear plant safety requirements around the world, including in the United States.

Resolution of the nation's high-level tank waste legacy requires the design, construction, and operation of large and technically complex one-of-a-kind processing waste treatment and vitrification facilities. While the ultimate limits for waste loading and melter efficiency have yet to be defined or realized, significant reductions in glass volumes for disposal and mission life may be possible with advancements in melter technologies and/or glass formulations. This test report describes the experimental results from a small-scale test using the research-scale melter (RSM) at Pacific Northwest National Laboratory (PNNL) to demonstrate the viability of iron-phosphate-based glass with a selected waste composition that is high in sulfate (4.37 wt% SO3). The primary objective of the test was to develop data to support a cost-benefit analysis related to the implementation of phosphate-based glasses for Hanford low-activity waste (LAW) and/or other high-level waste streams within the U.S. Department of Energy complex. The testing was performed by PNNL and supported by Idaho National Laboratory, Savannah River National Laboratory, Missouri University of Science and Technology, and Mo-Sci Corporation.

A letter report issued by the Government Accountability Office with an abstract that begins "Use of some preventive services--cardiovascular disease screening and cervical cancer screening--by FFS beneficiaries generally aligned with clinical recommendations, but use of other cancer screenings for certain age groups, osteoporosis screening, and immunizations did not. In particular, among women aged 65 to 74, for whom breast cancer screening is recommended biannually by the Task Force, only two out of three received a mammogram in 2008 or 2009. Among beneficiaries aged 65 to 75, about one out of four received any of the Task Force recommended regimens for colorectal cancer screening from 2005 through 2009. Among men aged 75 or older, about two out of five received a Prostate-Specific Antigen test for prostate cancer--a test that required no cost sharing--from 2006 through 2009 even though the Task Force recommended against this service for that age group. Use of osteoporosis screening--for which Medicare coverage is limited--and influenza and pneumococcal immunizations was generally lower than recommended by the Task Force or ACIP. The Department of Health and Human Services has the authority to modify coverage of Medicare preventive services--such as osteoporosis screening--consistent with Task Force recommendations."

For the 2010 ANS Embedded Topical Meeting on Decommissioning, Decontamination and Reutilization and Technology, Savannah River National Laboratory's Mike Serrato reported initial information on the newly developed specialty grout materials necessary to satisfy all requirements associated with in-situ decommissioning of P-Reactor and R-Reactor at the U.S. Department of Energy's Savannah River Site. Since that report, both projects have been successfully completed and extensive test data on both fresh properties and cured properties has been gathered and analyzed for a total of almost 191,150 m{sup 3} (250,000 yd{sup 3}) of new materials placed. The focus of this paper is to describe the (1) special grout mix for filling the P-Reactor vessel (RV) and (2) the new flowable structural fill materials used to fill the below grade portions of the facilities. With a wealth of data now in hand, this paper also captures the test results and reports on the performance of these new materials. Both reactors were constructed and entered service in the early 1950s, producing weapons grade materials for the nation's defense nuclear program. R-Reactor was shut down in 1964 and the P-Reactor in 1991. In-situ decommissioning (ISD) was selected for both facilities and performed as Comprehensive Environmental Response, Compensations …

The ARM Raman lidars are semi-autonomous ground-based systems that transmit at a wavelength of 355 nm with 300 mJ, {approx}5 ns pulses, and a pulse repetition frequency of 30Hz. Signals from the various detection channels are processed to produce time- and height-resolved estimates of several geophysical quantities, such as water vapor mixing ratio, relative humidity, aerosol scattering ratio, backscatter, optical depth, extinction, and depolarization ratio. Data processing is currently handled by a suite of six value-added product (VAP) processes. Collectively, these processes are known as the Raman Lidar Profiles VAP (RLPROF). The top-level best-estimate (BE) VAP process was introduced in order to bring together the most relevant information from the intermediate-level VAPs. As such, the BE process represents the final stage in data processing for the Raman lidar. Its principal function is to extract the primary variables from each of the intermediate-level VAPs, perform additional quality control, and combine all of this information into a single output file for the end-user. The focus of this document is to describe the processing performed by the BE VAP process.

A letter report issued by the Government Accountability Office with an abstract that begins "The Appraisal Subcommittee (ASC) has been performing its monitoring role under Title XI, but several weaknesses have potentially limited its effectiveness. For example, Title XI did not originally provide ASC rulemaking and enforcement tools that could be useful in promoting state compliance. In addition, ASC has not reported or clearly defined the criteria it uses to assess states’ overall compliance levels. Title XI charges ASC with monitoring the appraisal requirements of the federal financial institutions regulators, but ASC has not defined the scope of this function—for example, by developing policies and procedures—and its monitoring activities have been limited. ASC also lacks specific policies for determining whether activities of the Appraisal Foundation (a private nonprofit organization that sets criteria for appraisals and appraisers) that are funded by ASC grants are Title XI-related. Not having appropriate policies and procedures is inconsistent with federal internal control standards designed to promote effectiveness and efficiency and limits the accountability and transparency of ASC’s activities."

The magnetic domain structure in single crystals of a Heusler shape memory compound near the composition Fe{sub 2}MnGa was observed during phase transition by photoelectron emission microscopy at Beamline 11.0.1.1 of the Advanced Light Source. The behavior is comparable with recent observations of an adaptive martensite phase in prototype Ni{sub 2}MnGa, although the pinning in the recent work is an epitaxial interface and in this work the e#11;ective pinning plane is a boundary between martensitic variants that transform in a self-accommodating way from the single crystal austenite phase present at high temperatures. Temperature dependent observations of the twinning structure give information as to the coupling behavior between the magnetism and the structural evolution.
