Summary and evaluation of steel billet testing  

SciTech Connect

Tests were performed at Sandia National Laboratories (SNL) and Lawrence Livermore National Laboratory (LLNL) to assess loading conditions on a spent fuel storage cask for end drops, side drops and tipover events. The tests were performed with a 1/3-scale model billet and a 1/3-scale model concrete pad, and included a variety of substrate materials. A NUREG/CR report was prepared for the Nuclear Regulatory Commission (NRC) and provides a summary and an evaluation of all the billet testing conducted. This paper provides a description of the testing and analysis method, and a summary of the results. A generic or representative cask was modeled with the benchmarked finite element analysis approach and evaluated for ISFSI end and side drops and tipover events. The analytical method can be applied to similar casks to estimate deceleration loads on storage casks resulting from low-velocity drop or tipover impacts onto concrete storage pads.

Vadose Zone Transport Field Study: Summary Report  

SciTech Connect

From FY 2000 through FY 2003, a series of vadose zone transport field experiments were conducted as part of the U.S. Department of Energy’s Groundwater/Vadose Zone Integration Project Science and Technology Project, now known as the Remediation and Closure Science Project, and managed by the Pacific Northwest National Laboratory (PNNL). The series of experiments included two major field campaigns, one at a 299-E24-11 injection test site near PUREX and a second at a clastic dike site off Army Loop Road. The goals of these experiments were to improve our understanding of vadose zone transport processes; to develop data sets to validate and calibrate vadose zone flow and transport models; and to identify advanced monitoring techniques useful for evaluating flow-and-transport mechanisms and delineating contaminant plumes in the vadose zone at the Hanford Site. This report summarizes the key findings from the field studies and demonstrates how data collected from these studies are being used to improve conceptual models and develop numerical models of flow and transport in Hanford’s vadose zone. Results of these tests have led to a better understanding of the vadose zone. Fine-scale geologic heterogeneities, including grain fabric and lamination, were observed to have a strong effect on the large-scale behavior of contaminant plumes, primarily through increased lateral spreading resulting from anisotropy. Conceptual models have been updated to include lateral spreading and numerical models of unsaturated flow and transport have revised accordingly. A new robust model based on the concept of a connectivity tensor was developed to describe saturation-dependent anisotropy in strongly heterogeneous soils and has been incorporated into PNNL’s Subsurface Transport Over Multiple Phases (STOMP) simulator. Application to field-scale transport problems have led to a better understanding plume behavior at a number of sites where lateral spreading may have dominated waste migration (e.g. BC Cribs and Trenches). The improved models have been also coupled with inverse models and newly-developed parameter scaling techniques to allow estimation of field-scale and effective transport parameters for the vadose zone. The development and utility of pedotransfer functions for describing fine-scale hydrogeochemical heterogeneity and for incorporating this heterogeneity into reactive transport models was explored. An approach based on grain-size statistics appears feasible and has been used to describe heterogeneity in hydraulic properties and sorption properties, such as the cation exchange capacity and the specific surface area of Hanford sediments. This work has also led to the development of inverse modeling capabilities for time-dependent, subsurface, reactive transport with transient flow fields using an automated optimization algorithm. In addition, a number of geophysical techniques investigated for their potential to provide detailed information on the subtle changes in lithology and bedding surfaces; plume delineation, leak detection. High-resolution resistivity is now being used for detecting saline plumes at several waste sites at Hanford, including tank farms. Results from the field studies and associated analysis have appeared in more than 46 publications generated over the past 4 years. These publications include test plans and status reports, in addition to numerous technical notes and peer reviewed papers.

Summary of field operations, well TRN-1  

SciTech Connect

TRN-1 was drilled near the SE corner of Kirtland Air Force Base to a depth of 510 feet. This well is in the Site-Wide Hydrogeologic Characterization task field program, which is part of Sandia`s Environmental Restoration Project. After drilling, the borehole was logged, plugged to a depth of 352 ft, and completed as a monitoring well. Sand pack interval is from 305 to 352 ft and the screen interval is from 320 to 340 ft. During field operations, important subsurface geologic and hydrologic data were obtained (drill cuttings, geophysical logs of alluvial cover). Identification of the Abo formation in the subsurface will be useful. The subsurface hydrologic data will help define the local hydrostratigraphic framework within the bedrock. Future aquifer testing will be conducted for transmissivity, etc.

SIMS analysis: Development and evaluation program summary  

SciTech Connect

This report provides an overview of the ``SIMS Analysis: Development and Evaluation Program``, which was executed at the Idaho National Engineering Laboratory from mid-FY-92 to the end of FY-96. It should be noted that prior to FY-1994 the name of the program was ``In-Situ SIMS Analysis``. This report will not go into exhaustive detail regarding program accomplishments, because this information is contained in annual reports which are referenced herein. In summary, the program resulted in the design and construction of an ion trap secondary ion mass spectrometer (IT-SIMS), which is capable of the rapid analysis of environmental samples for adsorbed surface contaminants. This instrument achieves efficient secondary ion desorption by use of a molecular, massive ReO{sub 4}{sup {minus}} primary ion particle. The instrument manages surface charge buildup using a self-discharging principle, which is compatible with the pulsed nature of the ion trap. The instrument can achieve high selectivity and sensitivity using its selective ion storage and MS/MS capability. The instrument was used for detection of tri-n-butyl phosphate, salt cake (tank cake) characterization, and toxic metal speciation studies (specifically mercury). Technology transfer was also an important component of this program. The approach that was taken toward technology transfer was that of component transfer. This resulted in transfer of data acquisition and instrument control software in FY-94, and ongoing efforts to transfer primary ion gun and detector technology to other manufacturers.

Asymmetries and Visual Field Summaries as Predictors of Glaucoma in the Ocular Hypertension Treatment Study  

PubMed Central

Purpose To evaluate whether baseline visual field data and asymmetries between eyes predict the onset of primary open-angle glaucoma (POAG) in Ocular Hypertension Treatment Study (OHTS) participants. Methods A new index, mean prognosis (MP), was designed for optimal combination of visual field thresholds, to discriminate between eyes that developed POAG from eyes that did not. Baseline intraocular pressure (IOP) in fellow eyes was used to construct measures of IOP asymmetry. Age-adjusted baseline thresholds were used to develop indicators of visual field asymmetry and summary measures of visual field defects. Marginal multivariate failure time models were constructed that relate the new index MP, IOP asymmetry, and visual field asymmetry to POAG onset for OHTS participants. Results The marginal multivariate failure time analysis showed that the MP index is significantly related to POAG onset (P < 0.0001) and appears to be a more highly significant predictor of POAG onset than either mean deviation (MD; P = 0.17) or pattern standard deviation (PSD; P = 0.046). A 1-mm Hg increase in IOP asymmetry between fellow eyes is associated with a 17% increase in risk for development of POAG. When threshold asymmetry between eyes existed, the eye with lower thresholds was at a 37% greater risk of development of POAG, and this feature was more predictive of POAG onset than the visual field index MD, though not as strong a predictor as PSD. Conclusions The MP index, IOP asymmetry, and binocular test point asymmetry can assist in clinical evaluation of eyes at risk of development of POAG.

Field transportable beta spectrometer. Innovative technology summary report  

SciTech Connect

The objective of the Large-Scale Demonstration Project (LSDP) is to select and demonstrate potentially beneficial technologies at the Argonne National Laboratory-East (ANL) Chicago Pile-5 Test Reactor (CP-5). The purpose of the LSDP is to demonstrate that by using innovative and improved deactivation and decommissioning (D and D) technologies from various sources, significant benefits can be achieved when compared to baseline D and D technologies. One such capability being addressed by the D and D Focus Area is rapid characterization for facility contaminants. The technology was field demonstrated during the period January 7 through January 9, 1997, and offers several potential benefits, including faster turn-around time, cost reduction, and reduction in secondary waste. This report describes a PC controlled, field-transportable beta counter-spectrometer which uses solid scintillation coincident counting and low-noise photomultiplier tubes to count element-selective filters and other solid media. The dry scintillation counter used in combination with an element-selective technology eliminates the mess and disposal costs of liquid scintillation cocktails. Software in the instrument provides real-time spectral analysis. The instrument can detect and measure Tc-99, Sr-90, and other beta emitters reaching detection limits in the 20 pCi range (with shielding). Full analysis can be achieved in 30 minutes. The potential advantages of a field-portable beta counter-spectrometer include the savings gained from field generated results. The basis for decision-making is provided with a rapid turnaround analysis in the field. This technology would be competitive with the radiometric analysis done in fixed laboratories and the associated chain of custody operations.

Summary  

SciTech Connect

An effective risk assessment system is needed to address the threat posed by an active or passive insider who, acting alone or in collusion, could attempt diversion or theft of nuclear material. The material control and accountability (MC&A) system effectiveness tool (MSET) is a self-assessment or inspection tool utilizing probabilistic risk assessment (PRA) methodology to calculate the system effectiveness of a nuclear facility's material protection, control, and accountability (MPC&A) system. The MSET process is divided into four distinct and separate parts: (1) Completion of the questionnaire that assembles information about the operations of every aspect of the MPC&A system; (2) Conversion of questionnaire data into numeric values associated with risk; (3) Analysis of the numeric data utilizing the MPC&A fault tree and the SAPHIRE computer software; and (4) Self-assessment using the MSET reports to perform the effectiveness evaluation of the facility's MPC&A system. The process should lead to confirmation that mitigating features of the system effectively minimize the threat, or it could lead to the conclusion that system improvements or upgrades are necessary to achieve acceptable protection against the threat. If the need for system improvements or upgrades is indicated when the system is analyzed, MSET provides the capability to evaluate potential or actual system improvements or upgrades. A facility's MC&A system can be evaluated at a point in time. The system can be reevaluated after upgrades are implemented or after other system changes occur. The total system or specific subareas within the system can be evaluated. Areas of potential system improvement can be assessed to determine where the most beneficial and cost-effective improvements should be made. Analyses of risk importance factors show that sustainability is essential for optimal performance and reveals where performance degradation has the greatest impact on total system risk. The risk importance factors show the amount of risk reduction achievable with potential upgrades and the amount of risk reduction achieved after upgrades are completed. Applying the risk assessment tool gives support to budget prioritization by showing where budget support levels must be sustained for MC&A functions most important to risk. Results of the risk assessment are also useful in supporting funding justifications for system improvements that significantly reduce system risk. The functional model, the system risk assessment tool, and the facility evaluation questionnaire are valuable educational tools for MPC&A personnel. These educational tools provide a framework for ongoing dialogue between organizations regarding the design, development, implementation, operation, assessment, and sustainability of MPC&A systems. An organization considering the use of MSET as an analytical tool for evaluating the effectiveness of its MPC&A system will benefit from conducting a complete MSET exercise at an existing nuclear facility.

Summary of MATHEW/ADPIC model evaluation studies  

SciTech Connect

This report summarizes model evaluation studies conducted for the MATHEW/ADPIC transport and diffusion models during the past ten years. These models support the US Department of Energy Atmospheric Release Advisory Capability, an emergency response service for atmospheric releases of nuclear material. Field campaigns involving tracer releases used in these studies cover a broad range of meteorology, terrain and tracer release heights, the three most important aspects of estimating air concentration values resulting from airborne releases of toxic material. Results of these studies show that these models can estimate air concentration values within a factor of 2, 20% to 50% of the time and a factor of 5, 40% to 80% of the time. As the meteorology and terrain become more complex and the release height of the tracer is increased the accuracy of the model calculations degrades. This band of uncertainty appears to correctly represent the capability of these models at this time. 13 refs., 8 figs.

Coal liquefaction process streams characterization and evaluation. Volume 2, Participants program final summary evaluation  

SciTech Connect

This 4.5-year project consisted of routine analytical support to DOE`s direct liquefaction process development effort (the Base Program), and an extensive effort to develop, demonstate, and apply new analytical methods for the characterization of liquefaction process streams (the Participants Program). The objective of the Base Program was to support the on-going DOE direct coal liquefaction process development program. Feed, process, and product samples were used to assess process operations, product quality, and the effects of process variables, and to direct future testing. The primary objective of the Participants Program was to identify and demonstrate analytical methods for use in support of liquefaction process develpment, and in so doing, provide a bridge between process design, development, and operation and analytical chemistry. To achieve this direct coal liquefaction-derived materials. CONSOL made an evaluation of each analytical technique. During the performance of this project, we obtained analyses on samples from numerous process development and research programs and we evaluated a variety of analytical techniques for their usefulness in supporting liquefaction process development. Because of the diverse nature of this program, we provide here an annotated bibliography of the technical reports, publications, and formal presentations that resulted from this program to serve as a comprehensive summary of contract activities.

Summary of the Solar Two Test and Evaluation Program  

SciTech Connect

Solar Two was a collaborative, cost-shared project between eleven US industry and utility partners and the U. S. Department of Energy to validate molten-salt power tower technology. The Solar Two plant, located east of Barstow, CA, was comprised of 1926 heliostats, a receiver, a thermal storage system and a steam generation system. Molten nitrate salt was used as the heat transfer fluid and storage media. The steam generator powered a 10 MWe, conventional Rankine cycle turbine. Solar Two operated from June 1996 to April 1999. The major objective of the test and evaluation phase of the project was to validate the technical characteristics of a molten salt power tower. This paper describes the significant results from the test and evaluation activities.

SIMS analysis: Development and evaluation 1995 summary report  

SciTech Connect

Secondary ion mass spectrometry (SIMS) was evaluated for characterizing Hg salts. It was found that sulfate and chloride species could be identified directly without sample preparation. Mercuric oxide could be identified by complexation with formic acid. Hg nitrates could be identified by complexation with cyclohexylamine (CHA). Laser desorption ion trap MS was evaluated for characterizing EDTA on environmental samples. No intact EDTA ions were observed, but a series of EDTA fragment ions were visible, particularly on basalt and soil. An ion trap SIMS was developed: a perrhenate ion gun was interfaced to a Teledyne ion trap spectrometer, and the entire device was mounted on a cart. The technology was demonstrated using a prototype ion trap SIMS instrument for detecting Hg{center_dot}CHA complexes formed from nitrate salts. Intensity of the ion gun was improved, and the surface damage of the particle was small, and ion gun technology transfer to Phi-Evans, Inc. is being considered. Two technology end users are at INEL`s Central Facilities Area 674 pond and acid pit of the Radioactive Waste Management Complex; target problem at both sites is the need for Hg speciation on soil samples.

SIMS analysis: Development and evaluation 1994 summary report  

SciTech Connect

Secondary ion mass spectrometry (SIMS) was evaluated for applicability to the characterization of salt cake and environmental samples. Salt cake is representative of waste found in radioactive waste storage tanks located at Hanford and at other DOE sites; it consists of nitrate, nitrite, hydroxide, and ferrocyanide salts, and the samples form the tanks are extremely radioactive. SIMS is an attractive technology for characterizing these samples because it has the capability for producing speciation information with little or no sample preparation, and it generates no additional waste. Experiments demonstrated that substantial speciation information could be readily generated using SIMS: metal clusters which include nitrate, nitrite, hydroxide, carbonate, cyanide, ferrocyanide and ferricyanide were observed. In addition, the mechanism of SIMS desorption of tributyl phosphate (TBP) was clearly identified, and minimum detection limit studies involving TBP were performed. Procurements leading to the construction of an ion trap SIMS instrument were initiated. Technology transfer of SIMS components to three instrument vendors was initiated. For FY-95, the SIMS evaluation program has been redirected toward identification of metal species on environmental samples.

Method for cleaning performance evaluation using stable isotopes. Summary report  

SciTech Connect

The Aerospace Guidance and Metrology Center (AGMC) at Newark Air Force Base (NAFB), Ohio, has been using cleaning agents such as 1,1,1-Trichloroethane (TCA) and 1,1,2- Trichloro 1,2,2-trifluoroethane (Freon 113) for repair of inertial guidance equipment. Both of these cleaning agents have been classified as stratospheric ozone layer depleting substance (OLDS). Therefore, AGMC is interested in replacing these with other cleaning agents such as aqueous detergents. In order to assure that reliability and maintainability levels are not degraded when OLDS are phased out, a method is required to validate that the cleaning capability of the suggested alternative is at least as good as that of an existing, proven cleaning agent. The current methods used by AGMC to evaluate cleanliness are not effective when the parts being cleaned are composed of irregular or severe geometrics as is the case for precision gyroscopes and accelerometers repaired at AGMC. Therefore, AGMC funded Battelle to develop and demonstrate a suitable procedure for quantifying cleanliness. This report describes a cleaning performance evaluation procedure (CPEP) based on the use of stable isotopes. The CPEP developed and demonstrated in this project involved two phases. In Phase I, the contaminants which are present in the current cleaning processes were identified to select synthetic inorganic particulate and organic contaminants. In Phase II, unique, stable-isotopes of these contaminants were introduced into the parts followed by cleaning of these parts with various cleaning agents. The amounts of these unique isotopes extracted, as determined by mass spectroscopy (MS) provides a measure of cleaning efficiency.

Image quality evaluation of light field photography  

NASA Astrophysics Data System (ADS)

Light field photography captures 4D radiance information of a scene. Digital refocusing and digital correction of aberrations could be done after the photograph is taken. However, capturing 4D light field is costly and tradeoffs between different image quality metrics should be made and evaluated. This paper explores the effects of light field photography on image quality by quantitatively evaluating some basic criteria for an imaging system. A simulation approach was first developed by ray-tracing a designed light field camera. A standard testing chart followed by ISO 12233 was provided as the input scene. A sequence of light field raw images were acquired and processed by light field rendering methods afterwards. Through-focus visual resolution and MTF were calculated and analyzed. As a comparison, the same tests were taken for the same main lens system as the results of conventional photography. An experimental light field system was built up and its performance was tested. This work helps better understanding the pros and cons of light field photography in contrast with conventional imaging methods and perceiving the way to optimize the joint digital-optical design of the system.

Evaluation of heliostat field/receiver configurations  

SciTech Connect

This report evaluates and compares north heliostat field/cavity receiver configurations and surround heliostat field/external receiver configurations. The receiver coolants are molten nitrate salts and liquid sodium. Both field/receiver configurations use molten salt thermal storage; the sodium receiver is thermally connected to thermal storage by a sodium-to-salt heat exchanger. The heliostat filed size is fixed at 1,000,000 square meters of reflective area, and the delivered molten salt temperature is fixed at 566/sup 0/C. The delivered thermal power varies from 500 to 600 MW/sub t/, depending on the overall system efficiency. The generic north heliostat field/cavity receiver configurations were found to be 6 to 10 percent efficient than a generic surround field/external receiver configuration. There was little or no difference found in the transient performance of a molten salt receiver compared to a sodium receiver connected to a sodium-to-salt heat exchanger. Four configurations were of particular interest: (1) a north heliostat field/single cavity molten salt receiver, (2) a surround heliostat field/external cylinder molten salt receiver, (3) a surround heliostat field/external cylinder liquid sodium receiver, and (4) a north heliostat field/single cavity liquid sodium receiver. It was found that the surround field/liquid sodium external receiver configuration may provide energy at a 14 percent lower levelized energy cost than a north field/molten salt cavity receiver configuration. However, the cost advantage of the surround field/liquid sodium external receiver is not conclusive because of uncertainties in system component costs.

Summary of field operations Magazine Road North Wells MRN-1 and MRN-2  

SciTech Connect

This report provides a summary of the field operations associated with the installation of the MRN-1 and MRN-2 test/monitoring wells. These wells were installed in December 1994 and January 1995 as part of the Site-Wide Hydrogeologic Characterization (SWHC) task field program. The SWHC task is part of the Sandia National Laboratories, New Mexico, Environmental Restoration Project carried out by the Environmental Operations Center, 7500. MRN-1 and MRN-2 are paired wells located near the western edge of Kirtland Air Force Base (KAFB), west of Technical Area 3 (TA3), and north of Magazine Road. (Note: MRN stands for Magazine Road North). During the MRN field operations, important subsurface geologic, hydrologic, chemical, and radiological data were obtained. Subsurface geologic data include descriptions of drill cuttings, core, and geophysical logs of the upper unit of the Santa Fe Group. The geology identified here can help determine the eastern limit of the ancestral Rio Grande lithofacies. Subsurface hydrologic data include borehole geophysical logs, and qualitative information obtained during well completion and development. In addition, future aquifer testing at the MRN site will generate data for the interpretation of aquifer parameters such as transmissivity. Samples were taken from core every 100 feet at MRN-1 for chemical and radiological analysis to provide background data for the Environmental Restoration Project.

Simplified evaluation of magnetic field fluctuation thermometry  

NASA Astrophysics Data System (ADS)

Recently, a Bayesian approach has been proposed for evaluating magnetic field fluctuation thermometry measurements. The approach provides a coherent use of calibration results in the inference of the temperature from subsequent magnetic field fluctuation thermometry measurements. It does, however, rely on an extensive numerical effort. In this paper, we develop simplified parametric and non-parametric analysis schemes. For all approaches we derive analytic expressions for the resulting temperature estimates and their uncertainties. We assess the new approaches and show in particular that an easy to apply non-parametric analysis yields results which are in good agreement with those obtained by the Bayesian inference.

Entry control technology biometric field evaluations  

SciTech Connect

Throughout the years, Sandia National Laboratories (SNL) has performed various laboratory evaluations of entry control devices, including biometric identity verifiers. The reports which resulted from this testing have been very well received by the physical security community. This same community now requires equally informative field study data. To meet this need we have conducted a field study in an effort to develop the tools and methods which our customers can use to translate laboratory data into operational field performance. The field testing described in this report was based on the Recognition Systems Inc.`s (RSI) model ID3D HandKey biometric verifier. This device was selected because it is referenced in DOE documents such as the Guide for Implementation of the DOE Standard Badge and is the de facto biometric standard for the DOE. The ID3D HandKey is currently being used at several DOE sites such as Hanford, Rocky Flats, Pantex, Savannah River, and Idaho Nuclear Engineering Laboratory. The ID3D HandKey was laboratory tested at SNL. It performed very well during this test, exhibiting an equal error point of 0.2 percent. The goals of the field test were to identify operational characteristics and design guidelines to help system engineers translate laboratory data into field performance. A secondary goal was to develop tools which could be used by others to evaluate system effectiveness or improve the performance of their systems. Operational characteristics were determined by installing a working system and studying its operation over a five month period. Throughout this test we developed tools which could be used by others to similarly gauge system effectiveness.

An evaluation was completed to ascertain the applicability of line focus technologies to electrical power applications and to compare their performance and cost potential with point focus central receiver power systems. It was concluded that although the high temperature line focus (SRI) and fixed mirror line focus (GA) concepts duplicate the heat source characteristics and power conversion technology of the central receiver concepts these configurations do not offer a sufficient improvement in cost to warrant full scale development. The systems are, however, less complex than their point focus counterpart and should the central receiver system development falter they provide reasonable technology alternatives.

Field evaluation of the sulfur chemiluminescence detector  

SciTech Connect

A field evaluation of the sulfur chemiluminescence detector (SCD) as a real-time total atmospheric sulfur detector is presented. The SCD was installed in a monitoring trailer along with a flame photometric detector (FPD), fluorescent SO{sub 2} monitor (Fluor), and a suite of other monitoring instruments. The performance of the analyzers was compared for (1) baseline stability, (2) response stability, (3) interferences, (4) sensitive, and (5) environmental temperature effects. The SCD exhibited the best baseline stability and sensitivity, but had a drift in sensitivity larger than the other analyzers. The FPD and Fluor both showed interference effects, but none were observed for the SCD. Ambient temperature variations altered both the baseline and sensitivity of the FPD and the sensitivity of the Fluor. The SCD showed no ambient temperature dependence on either the baseline or sensitivity.

Hanford 100-D Area Biostimulation Soluble Substrate Field Test: Interim Data Summary for the Substrate Injection and Process Monitoring Phases of the Field Test  

SciTech Connect

Pacific Northwest National Laboratory is conducting a treatability test designed to demonstrate that in situ biostimulation can be applied to help meet cleanup goals in the Hanford Site 100-D Area. The in situ biostimulation technology is intended to provide supplemental treatment upgradient of the In Situ Redox Manipulation (ISRM) barrier by reducing the concentration of the primary oxidizing species in groundwater (i.e., nitrate and dissolved oxygen) and chromate, and thereby increasing the longevity of the ISRM barrier. This report summarizes the initial results from field testing of an in situ biological treatment zone implemented through injection of a soluble substrate. The field test is divided into operational phases that include substrate injection, process monitoring, and performance monitoring. The results summarized herein are for the substrate injection and process monitoring phase encompassing the first approximately three months of field testing. Performance monitoring is ongoing at the time this report was prepared and is planned to extend over approximately 18 months. As such, this report is an interim data summary report for the field test. The treatability testing has multiple objectives focused on evaluating the performance of biostimulation as a reducing barrier for nitrate, oxygen, and chromate. The following conclusions related to these objectives are supported by the data provided in this report. Substrate was successfully distributed to a radius of about 15 m (50 ft) from the injection well. Monitoring data indicate that microbial growth initiated rapidly, and this rapid growth would limit the ability to inject substrate to significantly larger zones from a single injection well. As would be expected, the uniformity of substrate distribution was impacted by subsurface heterogeneity. However, subsequent microbial activity and ability to reduce the targeted species was observed throughout the monitored zone during the process monitoring period, and low nitrate and oxygen concentrations were maintained. Chromate concentrations in the treatment zone began to increase about two months after substrate injection, up to about 30 percent of the background concentration upgradient of the test site. The performance monitoring phase will provide additional data to interpret the performance of the biostimulation process and information for scale-up as a reducing barrier.

Field evaluation of prototype electrofibrous filters  

SciTech Connect

New prototype electrofibrous filters were designed, built and evaluated in laboratory tests and in field installations. Two prototypes were designed for use in nuclear ventilation ducts as prefilters to HEPA filters. One prototype is designed to be a permanent component of the ventilation system while the other is a disposable unit. The disposable electrofibrous prefilter was installed in the exhaust stream of a glove box in which barrels of uranium turnings are burned. Preliminary tests show the disposal prefilter is effectively prolonging the HEPA filter life. An earlier prototype of the rolling prefilter was upgraded to meet the increased requirements for installation in a nuclear facility. This upgraded prototype was evaluated in the fire test facility at LLNL and shown to be effective in protecting HEPA filters from plugging under the most severe smoke conditions. The last prototype described in this report is a recirculating air filter. After demonstrating a high performance in laboratory tests the unit was shipped to Savannah River where it is awaiting installation in a Pu fuel fabrication facility. An analysis of the particulate problem in Savannah River indicates that four recirculating air filter will save $172,000 per year in maintenance costs.

Creation and Evaluation of EMR-based Paper Clinical Summaries to Support HIV-Care in Uganda, Africa  

PubMed Central

Purpose Getting the right information to providers can improve quality of care. We set out to provide patient-specific Electronic Medical Record (EMR)-based clinical summaries for providers taking care of HIV-positive adult patients in the resource-limited setting of Mbarara, Uganda. Methods We evaluated the impact of implementing these clinical summaries using time-motion techniques and provider surveys. Results After implementation of EMR-based clinical summaries, providers spent more time in direct care of patients (2.9 vs 2.3 minutes, p<0.001), and the length of patient visits was reduced by 11.5 minutes. Survey respondents indicated that clinical summaries improved care, reduced mistakes, and were generally accurate. Current antiretroviral medication, patient identifying information, adherence information, current medication, and current medical problems were among the highest-rated elements of the summary. Conclusions By taking advantage of data stored in EMRs, efficiency and quality of care can be improved through clinical summaries, even in settings with limited resources.

Summary report on reprocessing evaluation of selected inactive uranium mill tailings sites  

SciTech Connect

Sandia National Laboratories has been assisting the Department of Energy in the Uranium Mill Tailings Remedial Actions Program (UMTRAP) the purpose of which is to implement the provisions of Title I of Public Law 95-604, Uranium Mill Tailings Radiation Control Act of 1978.'' As part of this program, there was a need to evaluate the mineral concentration of the residual radioactive materials at some of the designated processing sites to determine whether mineral recovery would be practicable. Accordingly, Sandia contracted Mountain States Research and Development (MSRD), a division of Mountain States Mineral Enterprises, to drill, sample, and test tailings at 12 sites to evaluate the cost of and the revenue that could be derived from mineral recovery. UMTRAP related environmental and engineering sampling and support activities were performed in conjunction with the MSRD operations. This summary report presents a brief description of the various activities in the program and of the data and information obtained and summarizes the results. 8 refs., 9 tabs.

Summary and evaluation of low-velocity impact tests of solid steel billet onto concrete pads  

SciTech Connect

Spent fuel storage casks intended for use at independent spent fuel storage installations are evaluated during the application and review process for low-velocity impacts representative of possible handling accidents. In the past, the analyses involved in these evaluations have assumed that the casks dropped or tipped onto an unyielding surface - a conservative and simplifying assumption. Since 10 CFR Part 72, the regulation imposed by the Nuclear Regulatory Commission (NRC), does not require this assumption, applicants are currently seeking a more realistic model for the analyses to predict the effect of a cask dropping onto a reinforced concrete pad, including energy absorbing aspects such as cracking and flexure. To develop data suitable for benchmarking these analyses, the NRC has conducted several series of drop-test studies of a solid steel billet and of a near-full-scale empty cask. This report contains a summary and evaluation of all steel billet testing conducted by Sandia National Laboratories and Lawrence Livermore National Laboratory. A series of finite element analyses of the billet testing is described and benchmarked against the test data. A method to apply the benchmarked finite element model of the soil and concrete pad to an analysis of a full-size storage cask is provided. In addition, an application to a {open_quotes}generic{close_quotes} full-size cask is presented for side and end drops, and tipover events. The primary purpose of this report is to provide applicants for an NRC license under 10 CFR Part 72 with a method for evaluating storage casks for low-velocity impact conditions.

A summary of 22 Years of Fish Screen Evaluation in the Yakima River Basin, Summary Report 1985-2007.  

SciTech Connect

Sixty fish screen facilities were constructed in the Yakima River basin between 1985 and 2006 as part of the Northwest Power and Conservation Council plan to mitigate the effects of federal hydroelectric projects on fish and wildlife populations. This report summarizes evaluations of some of those and other fish screen facilities conducted by Pacific Northwest National Laboratory (PNNL) from 1985 through 2006. The objective of these studies was to determine if the newly designed and constructed fish screens were effective at providing juvenile salmonids safe passage past irrigation diversions. To answer that question, PNNL conducted release-and-catch studies at eight Phase I sites in the Yakima River basin. Increasing concerns about the impacts of hatchery fish releases on the wild fish population, as well as the cost and time necessary to perform these kinds of biological studies at more than 60 planned Phase II sites, required development of techniques to evaluate the effectiveness of the sites without releasing fish. The new techniques involved collecting information on screen design, operation, and effectiveness at guiding fish safely through the fish screen facility. Performance measures including water velocities and passage conditions provide a good alternative to biological studies at significantly lower cost and time. Physical techniques were used at all 10 Phase I and 28 Phase II sites evaluated by PNNL over the following 19 years. Results of these studies indicate the Phase I and II fish screen facilities are designed and capable of providing safe passage for juvenile salmonids so long as construction, maintenance, and operations meet the criteria used in the design of each site and the National Marine Fisheries Service criteria for juvenile fish screen design.

[Evaluation of cefuzonam in the pediatric field].  

PubMed

Cefuzonam (L-105, CZON) was studied in pediatric infections. A summary of the results it as follows: For recently isolated Staphylococcus aureus strains, Peak MICs of CZON were distributed between 0.39 and 0.78 micrograms/ml showing a greater susceptibility of S. aureus to CZON than to cefoperazone (CPZ), latamoxef (LMOX), and cefmenoxime (CMX). Peak MICs of CZON for Escherichia coli were 0.10-0.20 micrograms/ml, similar to those of CPZ, LMOX, and CMX. Ampicillin (ABPC)-resistant strains were also susceptible to CZON. MICs for Salmonella were similar to those for E. coli. Peak MICs of CZON for Vibrio parahaemolyticus were 0.20-0.39 micrograms/ml. The susceptibility of the bacteria to CZON was far greater than to ABPC, and was similar to CPZ, LMOX, and CMX. With 20 mg/kg drip infusion, serum concentrations reached their peaks at the end of administration with values of 20.6-68.7 micrograms/ml, which decreased to 0.43-1.70 micrograms/ml after 2 hours. Half-lives of CZON in serum were 0.68-1.2 hours. With 50 mg/kg drip infusion, serum concentrations reached their peaks at the end of administration with levels of 69.0-82.0 micrograms/ml, and at after 2 hours 1.85-3.45 micrograms/ml. Thus, an apparent dose response was observed. Half-lives of CZON in serum were 0.63-0.99 hours. Urinary recovery rates in 6 hours were 39.9-80.5%. A total of 44 cases of 10 different types of acute pediatric infections was treated by CZON intravenous drip infusion as the main therapeutic procedure. The efficacy rate was 93.2%, and the compound was effective on purulent infections, acute urinary tract infection, etc. with pathogens such as ABPC-resistant S. aureus, E. coli, and Enterococcus faecalis. Dosage levels per day were 50 to 80 mg/kg in most cases. In infections with S. aureus (8 strains), Streptococcus pneumoniae (3 strains), E. faecalis (1 strain), Haemophilus parahaemolyticus (1 strain), Haemophilus parainfluenzae (2 strains), Haemophilus influenzae (11 strains), Bordetella pertussis (1 strain), E. coli (3 strains), a total of 30 strains, bacterial elimination was noted with an exception of 1 strain of S. aureus. The compound was used for 4 to 15 days, but side effects observed clinically were only 1 case of diarrhea and 1 case of thrombocytosis. PMID:3613082

Summary of field-aligned Poynting flux observations from DE 2  

NASA Astrophysics Data System (ADS)

Using DE 2 data of ion drift velocities and magnetic fields, we have calculated the field-aligned Poynting flux (S?) for 576 orbits over the satellite lifetime. This is the first application over an extended data set of Poynting flux observations from in situ measurements. The data has been sorted by interplanetary magnetic field conditions (northward or southward IMF) and geomagnetic activity (Kp?3 and Kp>3) and binned by invariant latitude and magnetic local time. Our general results may be summarized as 1) the averaged S? is everywhere directed into the ionosphere, indicating that electric fields of magnetospheric origin generally dominate, and 2) the distribution of S? for southward IMF can be well explained in terms of an average two cell convection pattern, while for northward IMF a multiple cell convection pattern may be inferred. We have addressed the interesting question of the distribution of upward Poynting flux by binning only upward observations and found that average upward Poynting flux of less than 3 mW/m² may occur anywhere across the high latitude ionosphere. We have also observed a region at high latitudes in the predawn sector where the average upward Poynting flux is of significant size and occurrence frequency during southward IMF and high Kp conditions.

Summary of a 4-Year Fog Field Study in Northern Nanjing, Part 2: Fog Microphysics  

NASA Astrophysics Data System (ADS)

Comprehensive field observations of fog were conducted during the winters of 2006-2009 at the Nanjing University of Information Science & Technology, in order to study macro- and micro-physical structures and physical-chemical processes of dense fogs in northern Nanjing. The fog boundary-layer structures of different types and their corresponding characteristics are presented in Part I of these twin papers. In this second part, microphysical characteristics and droplet spectrum distributions of different types of fogs, microphysical relationships (among fog droplet concentration, liquid water content, and mean diameter), and microphysics of atmospheric aerosols during haze/fog events are discussed. The results show that there are large differences in microphysical parameters among four types of haze/fog. Many interesting phenomena, including fog burst reinforcement, fog droplet spectrum broadening, fog bimodal or multi-modal drop-size distributions, and critical triggering maxD value of fog coagulation growth, were captured during the 4-year field study.

Summary of field operations Powerline Wells PL-1, PL-2, PL-3  

SciTech Connect

This report summarizes field operations and hydrogeologic data obtained during installation of the Powerline monitoring/test wells near the western boundary of Kirtland Air Force Base. These wells were installed in 1994 as part of the Site-Wide Hydrogeologic Characterization Project saturated zone investigation. The Site-Wide Hydrogeologic Characterization Project is part of Sandia National Laboratories, New Mexico, Environmental Restoration Project. Three wells were drilled and completed at this location, and named PL-1, PL-2, and PL-3. They are located northwest of Tech Area 3, and are named after a high-voltage powerline located just south of the wells. The objectives of the Powerline wells were to determine the depth to water, complete 2 water table wells and a deeper Santa Fe Group well, to determine the geologic provenance of Santa Fe Group sediments at this location, and to obtain background core samples for radiological analysis. During these field operations, important subsurface hydrogeologic data were obtained. These data include drill cuttings and lithologic descriptions, core samples with background analytical data, geophysical logs, water quality parameters, and water levels. Aquifer tests at the Powerline location will generate data that may yield information on anisotropy in the Santa Fe Group and constrain numerical modeling results that indicate that there is a major northward component of groundwater flow from McCormick Ranch and Tech Area 3 test sites toward City of Albuquerque and KAFB well fields.

Evaluation of innovative arsenic treatment technologies :the arsenic water technology partnership vendors forums summary report.  

SciTech Connect

The lowering of the drinking water standard (MCL) for arsenic from 50 {micro}g/L to 10 {micro}g/L in January 2006 could lead to significant increases in the cost of water for many rural systems throughout the United States. The Arsenic Water Technology Partnership (AWTP), a collaborative effort of Sandia National Laboratories, the Awwa Research Foundation (AwwaRF) and WERC: A Consortium for Environmental Education and Technology Development, was formed to address this problem by developing and testing novel treatment technologies that could potentially reduce the costs of arsenic treatment. As a member of the AWTP, Sandia National Laboratories evaluated cutting-edge commercial products in three annual Arsenic Treatment Technology Vendors Forums held during the annual New Mexico Environmental Health Conferences (NMEHC) in 2003, 2004 and 2005. The Forums were comprised of two parts. At the first session, open to all conference attendees, commercial developers of innovative treatment technologies gave 15-minute talks that described project histories demonstrating the effectiveness of their products. During the second part, these same technologies were evaluated and ranked in closed sessions by independent technical experts for possible use in pilot-scale field demonstrations being conducted by Sandia National Laboratories. The results of the evaluations including numerical rankings of the products, links to company websites and copies of presentations made by the representatives of the companies are posted on the project website at http://www.sandia.gov/water/arsenic.htm. This report summarizes the contents of the website by providing brief descriptions of the technologies represented at the Forums and the results of the evaluations.

Comparison of induction motor field efficiency evaluation methods  

SciTech Connect

Unlike testing motor efficiency in a laboratory, certain methods given in the IEEE-Std 112 cannot be used for motor efficiency in the field. For example, it is difficult to load a motor in the field with a dynamometer when the motor is already coupled to driven equipment. The motor efficiency field evaluation faces a different environment from that for which the IEEE-Std 112 is chiefly written. A field evaluation method consists of one or several basic methods according to their physical natures. Their intrusivenesses and accuracies are also discussed. This study is useful for field engineers to select or to establish a proper efficiency evaluation method by understanding the theories and error sources of the methods.

Urban Dispersion Program MSG05 Field Study: Summary of Tracer and Meteorological Measurements  

SciTech Connect

The Urban Dispersion Program is a multi-year project, funded by the U.S. Department of Homeland Security, to better understand the flow and dispersion of airborne contaminants through and around the deep street canyons of New York City. The first tracer and meteorological field study was a limited study conducted during March 2005 near the Madison Square Garden in midtown Manhattan. Six safe, inert, gaseous perfluorocarbon tracers were released simultaneously at five street-level locations during two experimental days. In addition to collecting tracer data, meteorological data were also collected. Brookhaven National Laboratory conducted the bulk of the tracer and meteorological field efforts with Pacific Northwest National Laboratory and Stevens Institute of Technology assisting by measuring the vertical profile of winds. The Environmental Protection Agency worked with Brookhaven National Laboratory in accomplishing the personal exposure component of the study. This report presents some results from this analysis. In general, different release locations showed vastly different plume footprints for tracer materials, and the situation was made very complex with upwind and/or crosswind transport of tracer near street-level for the different release locations. Overall wind speeds and directions upwind and over the city were generally constant throughout each of the two experimental periods.

Summary of seasonal thermal energy storage field test projects in the United States  

SciTech Connect

Seasonal thermal energy storage (STES) involves storage of available heat or chill for distribution at a later time to meet thermal loads. STES can reduce energy consumption, peak energy demand, and emissions of carbon dioxide to the atmosphere over conventional systems. It is estimated that full-scale application of STES would provide 2% to 4% of total energy needs in the United States. One STES technology, aquifer thermal energy storage (ATES), has been determined to be the most cost-effective option in the United States when site conditions enable its use. ATES has been analyzed in the laboratory and investigated in the field in the United States since the program was established at Pacific Northwest Laboratory (PNL) in 1979. Two field test facilities (FTFs), one for heating ATES at the University of Minnesota and the other for cooling ATES at the University of Alabama, have been primary testing grounds for US ATES research. Computer models have been developed to analyze the complex thermal and fluid dynamics. Extensive monitoring of FTFs has provided verification of and refinements to the computer models. The areas of geochemistry and microbiology have been explored as they apply to the aquifer environment. In general, the two FTFs have been successful in demonstrating the steps needed to make an ATES system operational.

A controlled experiment to evaluate the use of a time-oriented summary medical record.  

PubMed

A randomized single-blind experiment was done in a medical subspecialty clinic in order to determine whether a flow-sheet type of summary medical record could validly serve as a means to communicate clinical information in the absence of the traditional medical record. Two groups of outpatient physician-patient encounters were compared: In the 68 study encounters (Group S), physicians were given a flow-sheet summary record with the option to receive the standard medical record if they desired; in the 27 control encounters (Group C), physicians were given the standard medical record plus the flow-sheet summary record. Fifty-nine per cent of study-group physicians did not choose to receive the full medical record. The study group was found not to differ (p = 0.013) from controls significantly with regard to the follow-up of clinical information as measured by pre- and post-encounter chart review. Physician providers in the study group were unable to detect by retrospective chart review overlooked clinical information with greater frequency than control group providers. We conclude that a flow-sheet type of summary medical record can serve as the sole source of clinical information in a substantial number of outpatient follow-up encounters in a medical subspecialty clinic without deterioration in the communication of clinical information.

Summary results of the Centralia partial seam CRIP underground coal gasification field test  

SciTech Connect

A field test of the controlled retracting injection point (CRIP) concept of underground coal gasification is described. The test utilized the high wall geometry of the Centralia open pit mine to gasify fourteen hundred cubic meters of coal over a thirty day period, using primarily steam and oxygen as the injected reactants. Three distinct periods of gasification are discussed: the initial period, using a vertical production well, which produced a gas heating value of 219 kJ/mole; a second slant production well period, yielding 261 kJ/mole gas following a successful CRIP maneuver; and third, a post roof collapse period during which the gas heating value dropped to 194 kJ/mole. 7 references, 11 figures, 4 tables.

Summary of a 4-Year Fog Field Study in Northern Nanjing, Part 1: Fog Boundary Layer  

NASA Astrophysics Data System (ADS)

Comprehensive fog field observations were conducted during the winters of 2006-2009 at the Nanjing University of Information Science and Technology to study the macro and micro-physical structures and the physical-chemical processes of dense fogs in the area. The observations included features of the fog boundary layer, characteristics of fog water, the particle spectrum, the chemical composition of atmospheric aerosols, radiation and heat components, turbulence, meteorological elements (air temperature, pressure, wind speed, wind direction), and environmental monitoring. The fogs observed were divided into four types: radiation fog, advection-radiation fog, advection fog, and precipitation fog, according to the mechanisms and primary factors of the fog processes. Fog boundary-layer structures of different types and their corresponding characteristics were then studied. Fog boundary-layer features, temperature structures, wind fields, and fog maintenance are discussed. The results show that radiation fog had remarkable diurnal variation and formed mostly at sunset or midnight, and lifted after sunrise or at noon, and that advection-radiation fog and advection fog were of very long duration. Extremely dense fogs occurred only in radiation-related cases. Inversion in radiation fog was short-lived, disappearing 1 or 2 hours after sunrise or at noon, faster than that in advection-radiation fog. When wind direction reversed from easterly to westerly or from southerly to northerly, the fog became an extremely dense fog. Low-level jet at times impeded fog development, whereas at other times it encouraged fog continuance. The deep inversion was merely an essential condition for a thick fog layer; sufficient vapor supply was advantageous to the formation and maintenance of a deep fog layer.

Family planning in Tunisia and Morocco: a summary and evaluation of the recent record.  

PubMed

Family planning activity during 1969-1970 in Morocco and Tunisia is discussed in terms of 12 criteria (such as leadership, educational services, availability) used to evaluate the programs in the 2 countries. Significant differences between family planning activity in the 2 countries can be seen in the nature of involvement of their governments through the open and public endorsement of family planning by Tunisia's president compared to the reserve of Morocco's king. Although family planning programs in both countries are organized within the Ministries of Health, the Tunisian program is conducted by a separate division, the Department of Family Planning and Maternal and Child Health, while Morocco's program is completely integrated within existing health services, a fusion which seems to create financial problems for the Moroccan family planning efforts. The Tunisian program, when compared to that of Morocco, is also characterized by a greater availability of contraceptives, more postpartum education and information activity, available induced-abortion and sterilization services, more widespread use of mass media and communication techniques and greater success in program evaluation. On a population basis, Tunisia (population of 5.2 million in 1970) has about 3 times the number of acceptors as Morocco (population of 15.4 million). Both programs have record-keeping systems which improved considerably during 1969 and 1970, but neither program has an effective field worker network. While Tunisia's program has demonstrated more success in meeting the criteria than Morocco's program and a slight decline has occurred in the crude birth rate in Tunisia in recent years, much of this decline can be attributed to a rising age at marriage resulting from the government's policies of social development. Evaluation indicated that both countries will have to increase availability of contraceptives and encourage effective use if substantial decreases in the crude birth rate are to be achieved.

Session 18: Geothermal Well Stimulation - Program Summary and the Beowawe Field Experiment  

SciTech Connect

Republic Geothermal, Inc. and its subcontractors have planned and executed laboratory studies and eight well stimulation field experiments under the Geothermal Reservoir Well Stimulation Program (GRWSP). The program, begun in February 1979, has concentrated on extending petroleum industry stimulation technology for use by the geothermal industry. The most recent experiment was in a naturally fractured Chevron well at Beowawe and involved an acid stimulation of a damaged interval which yielded a 2.3-fold increase in injectivity. Overall results to date have shown that stimulation is viable where adequate reservoirs are penetrated by wells encountering formation damage or locally tight formations. However, wells in marginal naturally fractured reservoirs have not been saved by the types of well stimulation jobs performed thus far. A recent discovery is that many wells can possibly be made outstanding producers by widening and propping compliant natural fractures. Confirmation of this constitutes unfinished business of the GRWSP, and offers one of the greatest potential opportunities for enhancing the economics of geothermal power production.

Summary of Past Microgravity Experiment in Japanese Microgravity Science Field and Future Plan  

NASA Astrophysics Data System (ADS)

strategic plan for the early years of the 21st century is described experiments were carried out onboard various flight platforms such as airplanes, sounding rockets, free-flyers, and space shuttles. In Japan, microgravity experiments started with Skylab in 1973. In this first set of experiments, the results were scrutinized with keen interest and the usefulness of microgravity environment was evidenced. In the 1980's, the Japanese sounding rocket TT-500A, which provided microgravity conditions for several minutes, was used to verify the experimental facilities and the operations before long duration microgravity experiments were carried out. With the First International Microgravity Laboratory (IML-1) and the First Material Processing Test (FMPT) projects, the National Space Development Agency of Japan (NASDA) had the opportunity to perform sustained and genuine microgravity experiments. With the twenty-two experiments carried out in the FPMT, the Japanese microgravity community made rapid progress. Following this, space missions such as the Second International Microgravity Laboratory (IML-2) and the First Microgravity Science Laboratory (MSL-1) were performed. In addition, a series of seven sounding rockets TR-IA were launched to investigate scientific problems and to help develop technologies. Through these flight experiments, material sciences (Electrostatic Levitation Furnace; the diffusion coefficient measurement by shear-cell method; in-situ simultaneous observation of temperature and concentration field by two wavelength Mach-Zehnder microscope Interferometer) became at the forefront of science and technology in the world. measurement, and cell biology, are being carried out as phase C of NASDA strategic research. Research solicitation in microgravity sciences, among other fields, has seen substantial progress since its initiation in 1997. It is hoped that grant awardees will be the potential applicants of ISS flight experiments in the future. The science experiments selected for flight to fulfill the initial Japanese Experimental Module payloads are reviewed periodically by the Space Utilization Research Program (SURP) and necessary support is provided to Pls to baseline their experiments. phase is proceeding as planned, having not met any major problems in the past year. Among these hardware, the Gradient Heating Furnace (GHF) provides a temperature gradient under vacuum conditions with three independent heating zones. The Advanced Furnace for Microgravity Experiment with X-Ray Radiography (AFEX) is a multi-user image furnace facility which is dedicated to material science experiments. It comprises a 2-axe X-ray radiographies, a visible image video, an infrared sensor, and 5-channel thermocouples allowing observation and measurement of the melt. The Fluid Physics Experiment Facility (FPEF) is mainly dedicated for fundamental fluid physics studies, including Marangoni convection research in liquid bridges. The Solution/Protein Crystal Growth Facility (SPCF) provides opportunity for fundamental science investigation of crystal growth in liquid solution, such as protein crystallization. International Announcement of Opportunity 2000" ("IAO 2000") and selected five research projects as Principal Investigator (PI) themes and three as Co-Investigator (CI) themes.

Seismic stability evaluation of Alben Barkley Lock and Dam Project. Volume 1. Summary report. Final report  

SciTech Connect

This report summarizes the results of seismological, geological, laboratory, field, and analytical investigations conducted to evaluate the seismic stability of two earth embankment sections of the Alben Barkley Lock and Dam Project, Kentucky. These represent typical sections of the powerhouse/switch-yard area and the main embankment. Detailed documentation of each of the major topical areas of this study are contained in Volumes 2 through 5 of this series of reports. The design earthquake, from the New Madrid Seismic Zone, had a body-wave magnitude of 7.5. Of particular interest in this study, was the seismic performance of silty sands in the foundation and their overall effect on the stability of these embankment sections. The results of this study indicate that large scale deformations and/or slope failure which would result in the loss of reservoir are not deformations on the order of 2 to 3 ft are expected. These deformations are relatively small in light of the fact that 28 ft of freeboard are expected to be available during the design earthquake.

Transportation of lignite to the North Island. Technical and economic evaluation of options. Summary report  

SciTech Connect

The report gives a summary of the findings of a study into the technical and economic aspects of transporting lignites from the South Island deposits to points of use in the north of the North Island. Economic analysis of transport options based on a 1250-MWe demand show that significant improvement in drying/processing techniques would be required before such an option could be favored. The costs are presented as a transport cost per ton and as a delivered fuel cost in terms of costs per kilowatt-hour. It is concluded that transport of lignites to the North Island is highly unlikely to present an attractive means of utilizing the South Island deposits.

Purpose To investigate the advantages of ultrawide-field fluorescein angiography (FA) over the standard fundus examination in the evaluation of diabetic retinopathy (DR). Methods Ultrawide-field FAs were obtained in 118 eyes of 59 diabetic patients; 11 eyes with no DR, 71 eyes with nonproliferative diabetic retinopathy (NPDR), and 36 eyes with proliferative diabetic retinopathy (PDR), diagnosed by the standard method. The presence of peripheral abnormal lesions beyond the standard seven fields was examined. Results Ultrawide-field FA images demonstrated peripheral microaneurysms in six (54.5%) of 11 eyes with no DR and all eyes with moderate to severe NPDR and PDR. Peripheral retinal neovascularizations were detected in three (4.2%) of 71 eyes with NPDR and in 13 (36.1%) of 36 eyes with PDR. Peripheral vascular nonperfusion and vascular leakage were found in two-thirds of eyes with severe NPDR and PDR. Conclusions Ultrawide-field FA demonstrates peripheral lesions beyond standard fields, which can allow early detection and a close evaluation of DR.

Development of a volumetric projection technique for the digital evaluation of field of view.  

PubMed

Current regulations for field of view requirements in road vehicles are defined by 2D areas projected on the ground plane. This paper discusses the development of a new software-based volumetric field of view projection tool and its implementation within an existing digital human modelling system. In addition, the exploitation of this new tool is highlighted through its use in a UK Department for Transport funded research project exploring the current concerns with driver vision. Focusing specifically on rearwards visibility in small and medium passenger vehicles, the volumetric approach is shown to provide a number of distinct advantages. The ability to explore multiple projections of both direct vision (through windows) and indirect vision (through mirrors) provides a greater understanding of the field of view environment afforded to the driver whilst still maintaining compatibility with the 2D projections of the regulatory standards. Practitioner Summary: Field of view requirements for drivers of road vehicles are defined by simplified 2D areas projected onto the ground plane. However, driver vision is a complex 3D problem. This paper presents the development of a new software-based 3D volumetric projection technique and its implementation in the evaluation of driver vision in small- and medium-sized passenger vehicles.

Brine Sampling and Evaluation Program 1992--1993 report and summary of BSEP data since 1982  

SciTech Connect

This report is the last one that is currently scheduled in the sequence of reports of new data, and therefore, also includes summary comments referencing important data obtained by BSEP since 1983. These BSEP activities document and investigate the origins, hydraulic characteristics, extent, and composition of brine occurrences in the Permian Salado Formation and seepage of that brine into the excavations at the (WIPP) Waste Isolation Pilot Plant. A project concern is that enough brine might be present after sealing and closure to generate large quantities of hydrogen gas by corroding the metal in the waste drums and waste inventory. This report describes progress made during the calendar years 1992 and 1993 and focuses on four major areas: (1) monitoring of brine inflow, e.g., measuring brines recovered from holes drilled downward from the underground drifts (downholes), upward from the underground drifts (upholes), and from subhorizontal holes from the underground drifts; (2) observations of weeps in the Air Intake Shaft (AIS); (3) further characterization of brine geochemistry; and (4) additional characterization of the hydrologic conditions in the fractured zone beneath the excavations.

Evaluation of DNA Force Fields in Implicit Solvation  

PubMed Central

DNA structural deformations and dynamics are crucial to its interactions in the cell. Theoretical simulations are essential tools to explore the structure, dynamics, and thermodynamics of biomolecules in a systematic way. Molecular mechanics force fields for DNA have benefited from constant improvements during the last decades. Several studies have evaluated and compared available force fields when the solvent is modeled by explicit molecules. On the other hand, few systematic studies have assessed the quality of duplex DNA models when implicit solvation is employed. The interest of an implicit modeling of the solvent consists in the important gain in the simulation performance and conformational sampling speed. In this study, respective influences of the force field and the implicit solvation model choice on DNA simulation quality are evaluated. To this end, extensive implicit solvent duplex DNA simulations are performed, attempting to reach both conformational and sequence diversity convergence. Structural parameters are extracted from simulations and statistically compared to available experimental and explicit solvation simulation data. Our results quantitatively expose the respective strengths and weaknesses of the different DNA force fields and implicit solvation models studied. This work can lead to the suggestion of improvements to current DNA theoretical models.

Summary of measured radiofrequency electric and magnetic fields (10 kHz to 30 GHz) in the general and work environment.  

PubMed

We have plotted data from a number of studies on the range of radiofrequency (RF) field levels associated with a variety of environmental and occupational sources. Field intensity is shown in units of volts/meter (V/m) for electric field strength and amps/meter (A/m) for magnetic field strength. Duty factors, modulation frequencies, and modulation indices are also reported for some sources. This paper is organized into seven sections, each cataloging sources into appropriate RF frequency bands from very-low frequency (VLF) to super-high frequency (SHF), and covers frequencies from 10 kHz to 30 GHz. Sources included in this summary are the following: Coast Guard navigational transmitters, a Navy VLF transmitter, computer visual display terminals (VDTs), induction stoves or range tops, industrial induction and dielectric heaters, radio and television broadcast transmitters, amateur and citizens band (CB) transmitters, medical diathermy and electrosurgical units, mobile and handheld transmitters, cordless and cellular telephones, microwave ovens, microwave terrestrial relay and satellite uplinks, and police, air traffic, and aircraft onboard radars. For the sources included in this summary, the strongest fields are found near industrial induction and dielectric heaters, and close to the radiating elements or transmitter leads of high power antenna systems. Handheld transmitters can produce near fields of about 500 V/m at the antenna. Fields in the general urban environment are principally associated with radio and TV broadcast services and measure about 0.1 V/m root-mean-square (rms). Peak fields from air traffic radars sampled in one urban environment were about 10 V/m, 300 times greater than the rms value of 0.03 V/m when the duty factor associated with antenna rotation and pulsing are factored in.

Summary of findings from the evaluation of a pilot medically supervised safer injecting facility.  

PubMed

In many cities, infectious disease and overdose epidemics are occurring among illicit injection drug users (IDUs). To reduce these concerns, Vancouver opened a supervised safer injecting facility in September 2003. Within the facility, people inject pre-obtained illicit drugs under the supervision of medical staff. The program was granted a legal exemption by the Canadian government on the condition that a 3-year scientific evaluation of its impacts be conducted. In this review, we summarize the findings from evaluations in those 3 years, including characteristics of IDUs at the facility, public injection drug use and publicly discarded syringes, HIV risk behaviour, use of addiction treatment services and other community resources, and drug-related crime rates. Vancouver's safer injecting facility has been associated with an array of community and public health benefits without evidence of adverse impacts. These findings should be useful to other cities considering supervised injecting facilities and to governments considering regulating their use. PMID:17116909

New spherical harmonic main field models for epochs 2005.0 (DGRF-2005) and 2010.0 (IGRF-2010), and predictive linear secular variation for the interval 2010.0-2015.0 (SV-2010-2015) were derived from weighted averages of candidate models submitted by teams led by DTU Space, Denmark (team A); NOAA/NGDC, U.S.A. (team B); BGS, U.K. (team C); IZMIRAN, Russia (team D); EOST, France (team E); IPGP, France (team F); GFZ, Germany (team G) and NASA-GSFC, U.S.A. (team H). Here, we report the evaluations of candidate models carried out by the IGRF-11 task force during October/November 2009 and describe the weightings used to derive the new IGRF-11 model. The evaluations include calculations of root mean square vector field differences between the candidates, comparisons of the power spectra, and degree correlations between the candidates and a mean model. Coefficient by coefficient analysis including determination of weighting factors used in a robust estimation of mean coefficients is also reported. Maps of differences in the vertical field intensity at Earth's surface between the candidates and weighted mean models are presented. Candidates with anomalous aspects are identified and efforts made to pinpoint both troublesome coefficients and geographical regions where large variations between candidates originate. A retrospective analysis of IGRF-10 main field candidates for epoch 2005.0 and predictive secular variation candidates for 2005.0-2010.0 using the new IGRF-11 models as a reference is also reported. The high quality and consistency of main field models derived using vector satellite data is demonstrated; based on internal consistency DGRF-2005 has a formal root mean square vector field error over Earth's surface of 1.0 nT. Difficulties nevertheless remain in accurately forecasting field evolution only five years into the future.

Field Tests for Evaluating the Aerobic Work Capacity of Firefighters  

PubMed Central

Working as a firefighter is physically strenuous, and a high level of physical fitness increases a firefighter’s ability to cope with the physical stress of their profession. Direct measurements of aerobic capacity, however, are often complicated, time consuming, and expensive. The first aim of the present study was to evaluate the correlations between direct (laboratory) and indirect (field) aerobic capacity tests with common and physically demanding firefighting tasks. The second aim was to give recommendations as to which field tests may be the most useful for evaluating firefighters’ aerobic work capacity. A total of 38 subjects (26 men and 12 women) were included. Two aerobic capacity tests, six field tests, and seven firefighting tasks were performed. Lactate threshold and onset of blood lactate accumulation were found to be correlated to the performance of one work task (rs?=??0.65 and ?0.63, p<0.01, respectively). Absolute (mL·min?1) and relative (mL·kg?1·min?1) maximal aerobic capacity was correlated to all but one of the work tasks (rs?=??0.79 to 0.55 and ?0.74 to 0.47, p<0.01, respectively). Aerobic capacity is important for firefighters’ work performance, and we have concluded that the time to row 500 m, the time to run 3000 m relative to body weight (s·kg?1), and the percent of maximal heart rate achieved during treadmill walking are the most valid field tests for evaluating a firefighter’s aerobic work capacity.

Algorithm Summary and Evaluation: Automatic Implementation of Ringdown Analysis for Electromechanical Mode Identification from Phasor Measurements  

SciTech Connect

Small signal stability problems are one of the major threats to grid stability and reliability. Prony analysis has been successfully applied on ringdown data to monitor electromechanical modes of a power system using phasor measurement unit (PMU) data. To facilitate an on-line application of mode estimation, this paper develops a recursive algorithm for implementing Prony analysis and proposed an oscillation detection method to detect ringdown data in real time. By automatically detecting ringdown data, the proposed method helps guarantee that Prony analysis is applied properly and timely on the ringdown data. Thus, the mode estimation results can be performed reliably and timely. The proposed method is tested using Monte Carlo simulations based on a 17-machine model and is shown to be able to properly identify the oscillation data for on-line application of Prony analysis. In addition, the proposed method is applied to field measurement data from WECC to show the performance of the proposed algorithm.

Summary and evaluation of hydraulic property data available for Eielson Air Force Base, Alaska  

SciTech Connect

Most of the contaminant source areas at Eielson Air Force Base are located above an unconfined alluvial aquifer with relatively high hydraulic conductivity. Hydraulic tests that have been conducted on wells at the base were evaluated, and in some cases reanalyzed, to determine hydraulic conductivity and specific yield for the aquifer. The reviewed tests included 2 multiple-well pumping tests and 30 slug tests. One slug test was conducted on a well in the bedrock aquifer at Site 38. All the other tests were conducted on the alluvial aquifer.

Isokinetic knee joint evaluation in track and field events.  

PubMed

The purpose of this study was to evaluate maximal torque of the knee flexors and extensors, flexor/extensor ratios, and maximal torque differences between the 2 lower extremities in young track and field athletes. Forty male track and field athletes 13-17 years old and 20 male nonathletes of the same age participated in the study. Athletes were divided into 4 groups according to their age and event (12 runners and 10 jumpers 13-15 years old, 12 runners and 6 jumpers 16-17 years old) and nonathletes into 2 groups of the same age. Maximal torque evaluation of knee flexors and extensors was performed on an isokinetic dynamometer at 60°·s(-1). At the age of 16-17 years, jumpers exhibited higher strength values at extension than did runners and nonathletes, whereas at the age of 13-15 years, no significant differences were found between events. Younger athletes were weaker than older athletes at flexion. Runners and jumpers were stronger than nonathletes in all relative peak torque parameters. Nonathletes exhibited a higher flexor/extensor ratio compared with runners and jumpers. Strength imbalance in athletes was found between the 2 lower extremities in knee flexors and extensors and also at flexor/extensor ratio of the same extremity. Young track and field athletes exhibit strength imbalances that could reduce their athletic performance, and specific strength training for the weak extremity may be needed. PMID:21869632

A Summary of Preclinical Topical Microbicide Rectal Safety and Efficacy Evaluations in a Pigtailed Macaque Model  

PubMed Central

Background There is widespread recognition of the potential promise of vaginal microbicides as a tool to combat global HIV/AIDS and STI epidemics, and candidate product development has maintained a rapid pace in recent years; however, rectal microbicide development has received less attention. As it is likely that commercial products developed for vaginal use will also be used rectally, there is a clear need to assess the safety and efficacy of candidate microbicide products specifically in the rectal compartment. Methods We have developed a standardized protocol for preclinical rectal safety and (chlamydial) efficacy assessment of topical microbicide candidates in a non-human primate model. We evaluated a total of twelve test compounds for rectal safety (via rectal pH, microflora, and rectal lavage) and one compound for efficacy against rectal chlamydial infection. Results In this paper, we describe our methods in detail and summarize our results, particularly noting the ability of our model to distinguish products with deleterious effects on the rectal environment. We also outline the specific criteria used to recommend products move into preclinical rectal efficacy trials or be recommended for reformulation to the product developer. In sum, we observed significant adverse effects in two products. The single product that underwent efficacy evaluation was not observed to be protective against rectal chlamydial infection. Conclusions A preclinical safety and efficacy model is critical to promoting rectal microbicide development, which will ultimately offer a significant opportunity for intervention in the global HIV/AIDS epidemic.

Summary of results from the National Renewable Energy Laboratory`s vehicle evaluation data collection efforts  

SciTech Connect

The U.S. DOE National Renewable Energy Laboratory conducted a data collection project for light-duty, alternative fuel vehicles (AFVs) for about 4 years. The project has collected data on 10 vehicle models (from the original equipment manufacturers) spanning model years 1991 through 1995. Emissions data have also been collected from a number of vehicles converted to natural gas (CNG) and liquefied petroleum gas (LPG). Most of the vehicles involved in the data collection and evaluation are part of the General Services Administration`s fleet of AFVs. This evaluation effort addressed the performance and reliability, fuel economy, and emissions of light- duty AFVs, with comparisons to similar gasoline vehicles when possible. Driver-reported complaints and unscheduled vehicle repairs were used to assess the performance and reliability of the AFVs compared to the comparable gasoline vehicles. Two sources of fuel economy were available, one from testing of vehicles on a chassis dynamometer, and the other from records of in-service fuel use. This report includes results from emissions testing completed on 169 AFVs and 161 gasoline control vehicles.

Use of field experimental studies to evaluate emergency response models  

SciTech Connect

The three-dimensional diagnostic wind field model (MATHEW) and the particle-in-cell atmospheric transport and diffusion model (ADPIC) are used by the Atmospheric Release Advisory Capability to estimate the environmental consequences of accidental releases of radioactivity into the atmosphere. These models have undergone extensive evaluations against field experiments conducted in a variety of environmental settings ranging from relatively flat to very complex terrain areas. Simulations of tracer experiments conducted in a complex mountain valley setting revealed that 35 to 50% of the comparisons between calculated and measured tracer concentrations were within a factor of 5. This may be compared with a factor of 2 for 50% of the comparisons for relatively flat terrain. This degradation of results in complex terrain is due to a variety of factors such as the limited representativeness of measurements in complex terrain, the limited spatial resolution afforded by the models, and the turbulence parameterization based on sigma/sub theta/ measurements to evaluate the eddy diffusivities. Measurements of sigma/sub theta/ in complex terrain exceed those measured over flat terrain by a factor of 2 to 3 leading to eddy diffusivities that are unrealistically high. The results of model evaluations are very sensitive to the quality and the representativeness of the meteorological data. This is particularly true for measurements near the source. The capability of the models to simulate the dispersion of an instantaneously produced cloud of particulates was illustrated to be generally within a factor of 2 over flat terrain. 19 refs., 16 figs.

Improved field experimental designs and quantitative evaluation of aquatic ecosystems  

SciTech Connect

The paired-station concept and a log transformed analysis of variance were used as methods to evaluate zooplankton density data collected during five years at an electrical generation station on Lake Michigan. To discuss the example and the field design necessary for a valid statistical analysis, considerable background is provided on the questions of selecting (1) sampling station pairs, (2) experimentwise error rates for multi-species analyses, (3) levels of Type I and II error rates, (4) procedures for conducting the field monitoring program, and (5) a discussion of the consequences of violating statistical assumptions. Details for estimating sample sizes necessary to detect changes of a specified magnitude are included. Both statistical and biological problems with monitoring programs (as now conducted) are addressed; serial correlation of successive observations in the time series obtained was identified as one principal statistical difficulty. The procedure reduces this problem to a level where statistical methods can be used confidently. 27 references, 4 figures, 2 tables.

Accurate evaluation of exchange fields in finite element micromagnetic solvers  

NASA Astrophysics Data System (ADS)

Quadratic basis functions (QBFs) are implemented for solving the Landau-Lifshitz-Gilbert equation via the finite element method. This involves the introduction of a set of special testing functions compatible with the QBFs for evaluating the Laplacian operator. The results by using QBFs are significantly more accurate than those via linear basis functions. QBF approach leads to significantly more accurate results than conventionally used approaches based on linear basis functions. Importantly QBFs allow reducing the error of computing the exchange field by increasing the mesh density for structured and unstructured meshes. Numerical examples demonstrate the feasibility of the method.

Sediment and radionuclide transport in rivers. Summary report, field sampling program for Cattaraugus and Buttermilk Creeks, New York  

SciTech Connect

A three-phase field sampling program was conducted on the Buttermilk-Cattaraugus Creek system to investigate the transport of radionuclides in surface waters as part of a continuing program to provide data for application and verification of Pacific Northwest Laboratory's (PNL) sediment and radionuclide transport model, SERATRA. Phase 1 of the sampling program was conducted during November and December 1977; Phase 2 during September 1978; and Phase 3 during April 1979. Bed sediment, suspended sediment, and water samples were collected over a 45-mile reach of the creek system. Bed sediment samples were also collected at the mouth of Cattaraugus Creek in Lake Erie. A fourth sampling trip was conducted during May 1980 to obtain supplementary channel geometry data and flood plain sediment samples. Radiological analysis of these samples included gamma ray spectrometry analysis, and radiochemical separation and analysis of Sr-90, Pu-238, Pu-239,240, Am-241 and Cm-244. Tritium analysis was also performed on water samples. Based on the evaluation of radionuclide levels in Cattaraugus and Buttermilk Creeks, the Nuclear Fuel Services facility at West Valley, New York, may be the source of Cs-137, Sr-90, CS-134, Co-60, Pu-238, Pu-239,240, Am-241, Cm-244 and tritium found in the bed sediment, suspended sediment and water of Buttermilk and Cattaraugus Creeks.

Particle bounce in a personal cascade impactor: a field evaluation.  

PubMed

The collection characteristics of five types of substrates (collection surfaces) used in personal cascade impactors were evaluated for particle bounce in the laboratory with lead dioxide dust, and in the field with brass pouring fume and brass grinding dust. The substrates tested were uncoated stainless steel, silicon grease-coated stainless steel, oil-saturated Millipore membrane filter, oil-saturated Teflon membrane filter and oil-saturated sintered stainless steel. The use of coated and uncoated stainless steel plates to collect lead dioxide dust produced no difference in measured mass median diameter (MMD); however, with brass grinding dust, there was a 50% decrease in measured MMD when uncoated stainless steel substrates were used, as compared with coated stainless steel substrates. Oil-saturated Millipore membrane surfaces gave consistently lower MMDs than coated stainless steel surfaces. Coated and uncoated stainless steel gave similar MMDs when used to sample brass pouring fume. Oil-saturated Teflon membrane and oil-saturated sintered metal, surfaces for which the collection efficiency is presumed to be independent of the particle loading, gave MMDs similar to those measured for grease-coated stainless steel. The implications of these comparisons are discussed. It is concluded that bounce characteristics are strongly dependent on aerosol material and the suitability of collection surfaces needs to be determined by field evaluation. PMID:4050689

Evaluation of bioaccumulation using in vivo laboratory and field studies.  

PubMed

A primary consideration in the evaluation of chemicals is the potential for substances to be absorbed and retained in an organism's tissues (i.e., bioaccumulated) at concentrations sufficient to pose health concerns. Substances that exhibit properties that enable biomagnification in the food chain (i.e., amplification of tissue concentrations at successive trophic levels) are of particular concern due to the elevated long-term exposures these substances pose to higher trophic organisms, including humans. Historically, biomarkers of in vivo chemical exposure (e.g., eggshell thinning, bill deformities) retrospectively led to the identification of such compounds, which were later categorized as persistent organic pollutants. Today, multiple bioaccumulation metrics are available to quantitatively assess the bioaccumulation potential of new and existing chemicals and identify substances that, upon or before environmental release, may be characterized as persistent organic pollutants. This paper reviews the various in vivo measurement approaches that can be used to assess the bioaccumulation of chemicals in aquatic or terrestrial species using laboratory-exposed, field-deployed, or collected organisms. Important issues associated with laboratory measurements of bioaccumulation include appropriate test species selection, test chemical dosing methods, exposure duration, and chemical and statistical analyses. Measuring bioaccumulation at a particular field site requires consideration of which test species to use and whether to examine natural populations or to use field-deployed populations. Both laboratory and field methods also require reliable determination of chemical concentrations in exposure media of interest (i.e., water, sediment, food or prey, etc.), accumulated body residues, or both. The advantages and disadvantages of various laboratory and field bioaccumulation metrics for assessing biomagnification potential in aquatic or terrestrial food chains are discussed. Guidance is provided on how to consider the uncertainty in these metrics and develop a weight-of-evidence evaluation that supports technically sound and consistent persistent organic pollutant and persistent, bioaccumulative, and toxic chemical identification. Based on the bioaccumulation information shared in 8 draft risk profiles submitted for review under the United Nations Stockholm Convention, recommendations are given for the information that is most critical to aid transparency and consistency in decision making.

Assessment of risk evaluation and mitigation strategies in oncology: summary of the oncology risk evaluation and mitigation strategies workshop.  

PubMed

To address oncology community stakeholder concerns regarding implementation of the Risk Evaluation and Mitigation Strategies (REMS) program, ASCO sponsored a workshop to gather REMS experiences from representatives of professional societies, patient organizations, pharmaceutical companies, and the US Food and Drug Administration (FDA). Stakeholder presentations and topical panel discussions addressed REMS program development, implementation processes, and practice experiences, as well as oncology drug safety processes. A draft REMS decision tool prepared by the ASCO REMS Steering Committee was presented for group discussion with facilitated, goal-oriented feedback. THE WORKSHOP IDENTIFIED SEVERAL UNINTENDED CONSEQUENCES RESULTING FROM CURRENT ONCOLOGY REMS: (1) the release of personal health information to drug sponsors as a condition for gaining access to a needed drug; (2) risk information that is not tailored-and therefore not accessible-to all literacy levels; (3) exclusive focus on drug risk, thereby affecting patient-provider treatment discussion; (4) REMS elements that do not consider existing, widely practiced oncology safety standards, professional training, and experience; and (5) administrative burdens that divert the health care team from direct patient care activities and, in some cases, could limit patient access to important therapies. Increased provider and professional society participation should form the basis of ongoing and future REMS standardization discussions with the FDA to work toward overall improvement of risk communication.

Evaluation of the reliability of soccer-specific field tests.  

PubMed

The soccer-specific field tests are popular among coaches due to their simplicity, validity, and minimal use of equipment. Nevertheless, there is a general lack of data about their reliability, particularly regarding the tests of anaerobic performance. Twenty professional male soccer players performed 3 consecutive trials of the tests of throwing-in and standing-kick performance (the distance measured) as well as on timed 10-m sprint, flying 20-m sprint, running 10 x 5 m, zigzag running with and without the ball, and the skill index (i.e., the ratio of the zigzag running without and with the ball). With the exception of the throwing-in and standing kick, the evaluated tests revealed high intraclass correlation coefficients (i.e., >0.80), small within-individual variations (coefficient of variation, <4%), and sample sizes for detecting a 2% change in the tested performance that are either close to or below the standard size of a professional soccer squad. In addition to simplicity and face validity, most of the evaluated tests revealed high reliability. Therefore, the evaluated tests are recommended for sport-specific profiling and early selection of young athletes as well as for routine testing procedures that could detect effects of various intervention procedures. Regarding the throwing-in and standing-kick tests, direct measurement of the ball velocity (e.g., with a standard radar gun) is recommended. PMID:18545209

Electromagnetic field spectral evaluation problems in exposure assessment.  

PubMed

Electromagnetic fields have become an omnipresent factor in our daily environment. It has become common that the exposure situations are characterised by a cocktail of spectral contributions from different sources, while exposures to single frequencies are rare. Thirty-two different types of drilling machines were analysed. Even similar devices exhibited large variations of emission levels up to two orders of magnitudes. It was found that emissions are not negligible and could be close or even above reference levels. Already single spectral peaks of magnetic emissions may considerably exceed reference levels, and excess can reach even the 90-fold when evaluating the entire spectrum. It is shown that approaches to assess complex frequency spectra as proposed by the International Commission on Non-Ionising Radiation Protection or defined in compliance standards issued by CENELEC or IEC lead to contradictory conclusions on conformity or non-conformity. There is an urgent need to clarify this discrepancy. PMID:17494982

Spectrally Enhanced Lighting Program Implementation for Energy Savings: Field Evaluation  

SciTech Connect

This report provides results from an evaluation PNNL conducted of a spectrally enhanced lighting demonstration project. PNNL performed field measurements and occupant surveys at three office buildings in California before and after lighting retrofits were made in August and December 2005. PNNL measured the following Overhead lighting electricity demand and consumption, Light levels in the workspace, Task lighting use, and Occupant ratings of satisfaction with the lighting. Existing lighting, which varied in each building, was replaced with lamps with correlated color temperature (CCT) of 5000 Kelvin, color rendering index (CRI) of 85, of varying wattages, and lower ballast factor electronic ballasts. The demonstrations were designed to decrease lighting power loads in the three buildings by 22-50 percent, depending on the existing installed lamps and ballasts. The project designers hypothesized that this reduction in electrical loads could be achieved by the change to higher CCT lamps without decreasing occupant satisfaction with the lighting.

Field Evaluation of Low-E Storm Windows  

SciTech Connect

A field evaluation comparing the performance of low emittance (low-e) storm windows with both standard clear storm windows and no storm windows was performed in a cold climate. Six homes with single-pane windows were monitored over the period of one heating season. The homes were monitored with no storm windows and with new storm windows. The storm windows installed on four of the six homes included a hard coat, pyrolitic, low-e coating while the storm windows for the other two homeshad traditional clear glass. Overall heating load reduction due to the storm windows was 13percent with the clear glass and 21percent with the low-e windows. Simple paybacks for the addition of the storm windows were 10 years for the clear glass and 4.5 years forthe low-e storm windows.

Evaluation of an electric field sensor for nondestructive material inspection  

NASA Astrophysics Data System (ADS)

An electric field sensor is fabricated on a 125 micron thick flexible dielectric substrate for electromagnetic (EM) nondestructive material inspection at 915 MHz. The sensor consists of an electrically short dipole antenna and a radio frequency (RF) diode detector connected to a pair of high impedance screen printed carbon lines. The DC component of the rectified diode voltage conveyed across the high impedance lines is measured using a data acquisition circuit. Sensor measurements are validated with simulated data for a conformal patch antenna operating at 915 MHz. Sensor performance for EM nondestructive testing (NDT) is evaluated using phantom defects in low loss dielectric slabs. Preliminary results indicate sensor utility for EM NDT and support further testing on realistic defects.

We tested technical-grade diazinon and its D Z N- 50W (50% diazinon active ingredient wettable powder) formulation on Canada goose (Branta canadensis) goslings. Brain acetylcholinesterase activity was measured, and the feathers and skin, feet. and gastrointestinal contents were analyzed for diazinon residues. The dose-response curves showed that diazinon was significantly more toxic to goslings in the outdoor test than in the laboratory tests. The deterministic risk assessment method identified the potential for risk to birds in general, but the factors associated with extrapolating from the laboratory to the field, and from the laboratory test species to other species, resulted in the underestimation of risk to the goslings. The present study indicates that laboratory-based risk quotients should be interpreted with caution.

Experimental evaluation of radiosity for room sound-field prediction.  

PubMed

An acoustical radiosity model was evaluated for how it performs in predicting real room sound fields. This was done by comparing radiosity predictions with experimental results for three existing rooms--a squash court, a classroom, and an office. Radiosity predictions were also compared with those by ray tracing--a "reference" prediction model--for both specular and diffuse surface reflection. Comparisons were made for detailed and discretized echograms, sound-decay curves, sound-propagation curves, and the variations with frequency of four room-acoustical parameters--EDT, RT, D50, and C80. In general, radiosity and diffuse ray tracing gave very similar predictions. Predictions by specular ray tracing were often very different. Radiosity agreed well with experiment in some cases, less well in others. Definitive conclusions regarding the accuracy with which the rooms were modeled, or the accuracy of the radiosity approach, were difficult to draw. The results suggest that radiosity predicts room sound fields with some accuracy, at least as well as diffuse ray tracing and, in general, better than specular ray tracing. The predictions of detailed echograms are less accurate, those of derived room-acoustical parameters more accurate. The results underline the need to develop experimental methods for accurately characterizing the absorptive and reflective characteristics of room surfaces, possible including phase. PMID:16938969

PRELIMINARY FIELD EVALUATION OF MERCURY CONTROL USING COMBUSTION MODIFICATIONS  

SciTech Connect

In this project General Electric Energy and Environmental Research Corporation conducts a preliminary field evaluation of a novel technology, referred to as Hg/NO{sub x}, that can reduce emissions of both mercury (Hg) and oxides of nitrogen (NO{sub x}) from coal-fired power plants. The evaluation takes place in Green Station Unit 2 operated by Western Kentucky Energy. Reduction of Hg and NO{sub x} emissions in Unit 2 is achieved using coal reburning. Activities during first project year (January 23, 2003--January 22, 2004) included measurements of baseline Hg emissions in Unit 2 and pilot-scale testing. Baseline testing of Hg emissions in Green Unit 2 has been completed. Two fuels were tested with OFA system operating at minimum air flow. Mercury emissions were measured at ESP inlet and outlet, and at the stack using Ontario Hydro revised method. Testing demonstrated that baseline Hg reductions at ESP outlet and stack were 30-45% and 70-80%, respectively. Pilot-scale testing demonstrated good agreement with baseline measurements in Unit 2. Testing showed that fuel composition had an effect on the efficiency of Hg absorption on fly ash. Maximum achieved Hg removal in reburning was close to 90%. Maximum achieved Hg reduction at air staging conditions was 60%. Testing also demonstrated that lowering ESP temperature improved efficiency of Hg removal.

Preliminary Field Evaluation of Mercury Control Using Combustion Modifications  

SciTech Connect

In this project EER conducted a preliminary field evaluation of the integrated approach for mercury (Hg) and NO{sub x} control. The approach enhanced the 'naturally occurring' Hg capture by fly ash through combustion optimization, increasing carbon in ash content, and lowering ESP temperature. The evaluation took place in Green Station Units 1 and 2 located near Henderson, Kentucky and operated by Western Kentucky Energy. Units 1 and 2 are equipped with cold-side ESPs and wet scrubbers. Green Station Units 1 and 2 typically fire two types of fuel: a bituminous coal and a blend of bituminous coals based on availability. Testing of Hg emissions in Unit 2 without reburning system in operation and at minimum OFA demonstrated that efficiencies of Hg reduction downstream of the ESP were 30-40%. Testing also demonstrated that OFA system operation at 22% air resulted in 10% incremental increase in Hg removal efficiency at the ESP outlet. About 80% of Hg in flue gas at ESP outlet was present in the oxidized form. Testing of Hg emissions under reburning conditions showed that Hg emissions decreased with LOI increase and ESP temperature decrease. Testing demonstrated that maximum Hg reduction downstream of ESP was 40-45% at ESP temperatures higher than 300 F and 60-80% at ESP temperatures lower than 300 F. The program objective to demonstrate 80% Hg removal at the ESP outlet has been met.

[Methods of dosimetry in evaluation of electromagnetic fields' biological action].  

PubMed

Theoretical and experimental dosimetry can be used for adequate evaluation of the effects of radiofrequency electromagnetic fields. In view of the tough electromagnetic environment in aircraft, pilots' safety is of particular topicality. The dosimetric evaluation is made from the quantitative characteristics of the EMF interaction with bio-objects depending on EM energy absorption in a unit of tissue volume or mass calculated as a specific absorbed rate (SAR) and measured in W/kg. Theoretical dosimetry employs a number of computational methods to determine EM energy, as well as the augmented method of boundary conditions, iterative augmented method of boundary conditions, moments method, generalized multipolar method, finite-element method, time domain finite-difference method, and hybrid methods combining several decision plans modeling the design philosophy of navigation, radiolocation and human systems. Because of difficulties with the experimental SAR estimate, theoretical dosimetry is regarded as the first step in analysis of the in-aircraft conditions of exposure and possible bio-effects.

Design, performance, and evaluation of the uniflood micellarpolymer process--Bell Creek Field  

SciTech Connect

Gary Energy Corporation conducted a DOE cost-shared 40-acre Demonstration Pilot project to determine whether or not micellar-polymer flooding is a feasible technique to enhance oil recovery from the Bell Creek Field, Montana. Water injection into the new 40-acre 5-spot pilot pattern began in October 1977 and was to be followed immediately by the micellar-polymer process. However, the complex reservoir definition work extended this pilot 5-spot waterflood to fifteen months, through January 1979. The micellarpolymer (Uniflood) process commenced in February 1979 with preflush injection (16.4% PV); micellar slug injection (3.8% PV) began August 1979 and polymer injection (100% PV) began October 1979. The average remaining oil saturation in the 40 acres was estimated to be 30.5% at the start of chemical injection. This paper includes a summary of the micellarpolymer process design, the micellar-polymer oil recovery results projected to project completion, an analysis of the geology and fluid chemistry within the pilot area, and an interpretation and evaluation of the overall performance of the project. A high pH preflush and the use of a chelating agent in the micellar slug minimized the effects of the multivalent ions present in the reservoir. Also, adjustments in the components used in the soluble oil slug made it possible to regain a favorable phase relationship with the reservoir fluids despite the lower-than-design quality sulfonates.

Field evaluation of nitrogen availability from fresh and composted manure.  

PubMed

Prediction of manure nitrogen availability to crops is key to ensuring adequate production while minimizing potential adverse environmental impacts. This field study estimated first-year and residual N availability from several manures subjected to various levels of processing, and evaluated the applicability of the pre-sidedress soil N test (PSNT) in fields receiving the different manures using corn (Zea mays L.) as the test crop. Plots received several rates of fresh (FP), dried (DP), or composted (CP) poultry (Gallus gallus domesticus) manure, composted cow (Bos taurus) (CC) manure, ammonium nitrate (AN), or no N. Crop yields and N uptake from plots where CC was applied were undistinguishable from controls in most years, whereas poultry manures significantly increased corn production. Average apparent first-year N availability, as measured by fertilizer equivalence, was 57, 53, 14, and 4% for FP, DP, CP, and CC respectively. Apparent second-year N availability, as measured by relative effectiveness, was 18, 19, 12, and 7% for FP, DP, CP, and CC; however, for CC both first- and second-year estimates of apparent N recovery (ANR) could statistically not be separated from the controls. Apparent nitrogen avail-ability was greater for less processed manures and for CP compared to CC, emphasizing that producers should know the source and level of compost stability when these materials are used as a primary nutrient source. The PSNT successfully (87% correct) identified sites with a critical value of 24 mg kg(-1) that were N sufficient across a variety of N amendments from those that would have benefitted from additional N input.

Coastal zone wind energy. Part II: Validation of the coastal zone wind power potential. A summary of the field experiment  

SciTech Connect

Procedures have been developed to determine the wind power potential of the coastal region from Maine to Texas. The procedures are based upon a climatological analysis and a mesoscale numerical model. The results of this procedure are encouraging but need to be tested. In January to February 1980 a field measurement program was carried out over the Delmarva Peninsula centered on Wallops Island and extending into the Atlantic Ocean and Chesapeake Bay to provide an observational basis on which to test our wind assessment methods. The field experiment is described. Listings of the measurements made by aircraft, tethered balloon, rawinsonde kites, tower mounted anemometry and surface thermometry are given together with sample results. The analysis of these data and the comparison between them and the model predicted fields are presented.

Biological studies of swine exposed to 60-Hz electric fields. Volume 1. Overview and summary. Final report  

SciTech Connect

Over a three-year period, three generations of female miniature swine and their offspring were exposed to a 30-kV/m, 60-Hz electric field. Such a field approximates the 12-kV/m field that a human would experience under a 765-kV line. After swine exposures varying from 6 to 36 months, project personnel analyzed a wide range of biological parameters including growth, blood cell and serum biochemistry, blood immunoglobulin levels, behavior, peripheral nerve function, cell-mediated immunity, cytogenetics, and reproduction and development. There were no significant differences in health effects between the exposed and sham-exposed swine, except in the area of fetal development. The first breeding produced no significant difference between exposed and control offspring. When those offspring were bred after 18 months of exposure, the fetuses of exposed sows had an increased incidence of morphological malformations and lower body weight than fetuses from control sows. The live-born had lower body weights and increased birth defects. Several factors suggest that electric fields per se may not have caused these reproductive changes. For example, similar types of malformations occurred in control pigs. Also, in second-generation sows, the incidence of fetal malformations was similar for both exposed and control groups. It is possible that other factors such as housing, inbreeding, disease, or treatment of disease may have produced the observed effects. 64 refs., 13 figs., 25 tabs.

Development and evaluation of field methods for ammonia in air.  

PubMed

Three methods for measuring ammonia in air have been evaluated. Filters impregnated with 10% (volume/volume) phosphoric acid in methanol were used for two methods. Sampling was done either with a filter cassette connected to a pump or with the filters placed in a passive monitor (Gasbadge). The filters were leached with distilled water after the sampling and analyzed with ion chromatography or colorimetry (Nessler). The third method tested was a colorimetric air-monitoring badge system (ProTek). The tests showed that the accuracy of the filter methods is good and that the results are not affected by humidity. If ion chromatography is used for the analysis, amines do not interfere. The Gasbadge monitors increased their uptake when the air velocity over the sampler was raised from 0.2 to 1.0 m/s. The accuracy of the ProTek method was poor, the method was biased, and blank samples showed high values. In field tests carried out in a foundry and at a fertilizer plant, the agreement between the filter methods was good, whereas the results of the ProTek method deviated drastically from those of the other methods.

Electrodographic analysis and field evaluation of the Speak coding strategy.  

PubMed

The Speak speech-coding strategy for the Nucleus Minisystem-22 cochlear implant continuously analyzes the speech signal using 20 digitally programmable band-pass filters and presents up to 10 spectral maxima to the implanted electrodes. To analyze the performance of this system for a variety of speech sounds in quiet and noise, the stimulation patterns of the implanted electrode array were reconstructed from the transmitted radio frequency signals by software as electrodograms and compared to electrodograms generated by other speech-coding strategies, as well as to the spectrograms of the input signals. The performance with the Speak strategy relative to that with the Multipeak (Mpeak) speech-processing strategy was also evaluated in a field trial study with 20 native German-speaking cochlear implant users from four European implant centers, involving a variety of auditory perceptual tasks in an ABAB paradigm over a 12-week period. Vowel, consonant, and monosyllable word tests, as well as sentence tests in quiet and noise, were conducted. Significant differences in group mean scores for most speech recognition subtests were obtained for the Speak versus the Mpeak strategy, with the largest overall improvements observed for the sentence tests in noisy conditions.

Evaluation of different field methods for measuring soil water infiltration  

NASA Astrophysics Data System (ADS)

Soil infiltrability, together with rainfall characteristics, is the most important hydrological parameter for the evaluation and diagnosis of the soil water balance and soil moisture regime. Those balances and regimes are the main regulating factors of the on site water supply to plants and other soil organisms and of other important processes like runoff, surface and mass erosion, drainage, etc, affecting sedimentation, flooding, soil and water pollution, water supply for different purposes (population, agriculture, industries, hydroelectricity), etc. Therefore the direct measurement of water infiltration rates or its indirect deduction from other soil characteristics or properties has become indispensable for the evaluation and modelling of the previously mentioned processes. Indirect deductions from other soil characteristics measured under laboratory conditions in the same soils, or in other soils, through the so called "pedo-transfer" functions, have demonstrated to be of limited value in most of the cases. Direct "in situ" field evaluations have to be preferred in any case. In this contribution we present the results of past experiences in the measurement of soil water infiltration rates in many different soils and land conditions, and their use for deducing soil water balances under variable climates. There are also presented and discussed recent results obtained in comparing different methods, using double and single ring infiltrometers, rainfall simulators, and disc permeameters, of different sizes, in soils with very contrasting surface and profile characteristics and conditions, including stony soils and very sloping lands. It is concluded that there are not methods universally applicable to any soil and land condition, and that in many cases the results are significantly influenced by the way we use a particular method or instrument, and by the alterations in the soil conditions by the land management, but also due to the manipulation of the surface soil before and during the measurement. Due to the commonly found high variability, natural or induced by land management, of the soil surface and subsurface hydrological properties, and to the limitations imposed by the requirements of water for the measurements, there is proposed a simple and handy method, which do not use high volumes of water, adaptable to very different soil and land conditions, and that allow many repeated measurements with acceptable accuracy for most of the purposes.

Recently, a prototype of a field-scale (2-5 ha), vegetated, capillary surface barrier was constructed over a waste zone at the semiarid Hanford Site in southeast Washington. The barrier is instrumented to measure the components of water balance under ambient and elevated precipitation scenarios on soil and rock-covered plots. The barrier also allows for the evaluation of two protective side slope configurations, and the monitoring of flow around and under a low permeability asphalt layer. The first 2 yr of testing were unusually wet, with precipitation more than twice the long-term annual average of 160 mm. Even with an imposed irrigation treatment of 480 mm yr{sup -1}, including a simulated 1000-yr storm event each year, there was no drainage from the soil covered plots. This demonstrates the effectiveness of vegetated capillary barriers in an and environment. Each year, plants used all available water, independent of precipitation treatment, reducing soil water storage to the same lower limit by the end of summer. The soil was wettest during spring, but water storage never exceeded 450 mm in the 2-m thick soil layer, which was designed to store 600 mm. The efficiency of ET was consistently higher on the ambient treatment, suggesting a susceptibility of native plant species to high levels of precipitation. No water has penetrated the low-permeability asphalt layer, although an unprotected section of the toe showed a potential for underflow. While there was no difference in total drainage from the irrigated side slopes over the last 2 yr, the nonirrigated basalt slope drained 55% less water than the gravel. Side slope drainage also showed a seasonal dependence, with the gravel draining more than the basalt in winter and less in the summer. Drainage rates and volumes appear to be controlled by advective airflow. 18 refs., 9 figs., 1 tab.

SciTech Connect

Tight gas fields, reservoirs, and completions have been identified in all non-Appalachian U.S. basins containing tight formation designations specified by the Federal Energy Regulatory Commission. A total of 909 fields containing 1,643 tight reservoirs and 37,074 tight gas completions have been identified (through 1988). Non-Appalachian tight production increased from 0.88 Tcf per year in 1970 to 1.71 Tcf per year in 1985 before declining slightly to 1.65 Tcf in 1988. Tight ultimate recovery (cumulative production plus proven reserves) is estimated to be 52.3 Tcf. Evaluation includes basin and formation level evaluation of completion counts, production, ultimate recovery, field size distribution and well density.

Field evaluation of a modified intervention for overhead drilling.  

PubMed

Drilling holes into concrete or metal ceilings is one of the most physically demanding tasks performed in construction. The work is done overhead with rotary impact hammer drills that weigh up to 40 N. The task is associated with pain and musculoskeletal disorders at the wrist, forearm, shoulder, and back. The mechanism of injury is thought to be the high forces and non-neutral shoulder and wrist postures applied during drilling. Previously, we described a field study of a foot lever and inverted drill press intervention devices that received poor usability ratings compared with the usual method for overhead drilling based on problems with mobility and productivity. Using a participatory intervention model, feedback from construction workers (N = 13) was used to develop a new intervention design that incorporated a wheeled tripod base and a unique method of aligning the drilling column to vertical. A different group of construction workers (N = 23) evaluated usability and fatigue of the new device during their regular overhead drilling in comparison with the usual method. Four of 12 usability ratings were significantly better with the intervention device compared with the usual method. Subjective shoulder fatigue was less with the new intervention (1.1 vs. 3.3; scale 0 to 5; p < 0.001). This difference was supported by objective outcome measures; the mean hand forces during drilling were 26 N with the intervention compared with 245 N with the usual method. The percentage of time with the shoulder flexed or abducted to more than 60 degrees was less with the intervention compared with the usual method (21 vs. 40%; p = 0.007). There was significantly less head extension with the intervention compared with the usual method. There were no significant differences in overall productivity between the two methods. This study demonstrates that a new intervention device for overhead drilling has improved usability and subjective fatigue ratings compared with the usual method. These improvements are most likely due to the reduced hand forces, reduced shoulder abduction and flexion, and reduced drilling time. PMID:20094939

Evaluation of PMU Dynamic Performance in Both Lab Environments and under Field Operating Conditions  

SciTech Connect

Abstract—Capturing system dynamics is one important feature of phasor measurements. To ensure PMU accurately reflect system dynamic behavior, one must evaluate the dynamic performance of a PMU. PMU dynamic performance evaluation includes three aspects: PMU modeling studies, laboratory testing and field evaluation. This paper briefly reviews the general PMU model structure, and then continues on PMU dynamic performance evaluation from actual field measurements. Reasons for field evaluation include: 1) inappropriate field settings of a PMU would generate unexpected phasor measurements; and 2) many conditions can not be easily produced in a lab environment. PMU field evaluation includes aspects like time synchronization, timing inconsistency due to filtering, frequency calculation issues, parasitic oscillations/processing artifacts, etc. Actual WECC measurement examples will be presented. Dynamic PMU testing in a lab environment is explored with a special focus on PMU filtering characteristics. How the phasor quality would impact derived system dynamic characteristics is addressed in the later part of this paper.

A soil vapor extraction pilot study in a deep arid vadose zone. Part 1: field study summary  

SciTech Connect

Non-radioactive liquid chemical waste was disposed at Material Disposal Area (MDA) L within Technical Area 54 (TA-54) at the Los Alamos National Laboratory (LANL) from the early 1960's until 1985. Three surface impoundments, one pit, and 34 vertical shafts comprise the MDA L disposal facilities. None of the disposal areas were lined. Under LANL's Environmental Program, extensive sampling and analysis have been conducted to characterize the vadose zone beneath MDA L and to determine the nature and extent of contaminant releases from the former disposal units. The major contaminant release at the site is a subsurface organic solvent vapor-phase plume consisting primarily of several chlorinated volatile organic compounds (CVOCs) including 1,1,1-trichloroethane (TCA), trichloroethene (TCE), Freon, tetrachloroethene (PCE). TCA was found in the greatest concentration, constituting the majority of the plume mass, and it also exhibits the greatest lateral and vertical extent in the organic vapor plume. A numerical model to characterize the subsurface plume has been developed based on the site conceptual model and refined using data from ongoing compliance monitoring. The primary goal of the pilot test was to provide information necessary to determine the effectiveness of SVE as a treatment method for the VOC vapor plume. To achieve this objective, commercially available SVE equipment meeting functional requirements established by previous vapor extraction testing and extensive vadose zone characterization activities was leased, temporarily installed, and operated at each of two test extraction wells in sequence. Granular activated carbon was used to treat the SVE emissions. Subsurface vapor monitoring captured the reduction in soil vapor concentrations and subsurface pressure changes. Active extraction was conducted from extraction wells constructed near the source term over a two-month period, resulting in the removal of more than 800 lbs of VOCs. Rebound monitoring was conducted to provide information on the nature of the source. Rebound monitoring indicated a fairly rapid source response, with preliminary data showing concentrations in monitoring boreholes closest to the source reaching steady state at concentrations lower than pre-test levels. Data from this study will be used to refine the MDAL L numerical model in order to assess the long term effectiveness of SVE as a remedy for the subsurface vapor-phase plume at MDA L in support of the corrective measure evaluation for MDA L.

The Pacific Dust Experiment (PaCDEX) Field Campaign: A summary of accomplishments during the field campaign and examples of early results.  

NASA Astrophysics Data System (ADS)

The Pacific Dust Experiment (PACDEX) is a pilot study utilizing quasi-Lagrangian sampling of the Asian dust and pollution plumes as they travel across the Pacific Ocean and interact with clouds and maritime weather systems. The NSF/NCAR G-V aircraft was used, guided by daily chemical forecasts, to follow dust events at various Pacific locations during the eastbound transit towards North America. Objectives of PACDEX include identification of the principal cloud-active and black carbon aerosols in the Asian plume, documenting changes in cloud hydrometeors in regions affected by the plumes, documenting the solar changes in the plume vertical structure in clear and cloudy regions, and examining differences in these variables among Western and Eastern Pacific plumes. Fourteen research flights were conducted in April and May 2007. Asian dust events were followed across much of the Pacific Ocean at altitudes from 11 km to near the surface. Cross-frontal sampling in several extratropical storms was conducted at multiple altitudes in regions where the plumes were found. Ice forming nuclei (IN) activation spectra (at various supersaturations and temperatures) were obtained in several dust regions, polluted regions, and in background air. Early results from the field project suggest that Asian dust serves as an important source of IN to maritime clouds, and that anthropogenic Asian emissions, particularly CO and black carbon, are effectively incorporated into the upper regions of extratropical storm clouds.

Rotating field collector subsystem Phase I study and evaluation  

SciTech Connect

The rotating field collector system is an alternative concept in which all heliostats are mounted on a single large platform which rotates around a tower to track the azimuthal angle of the sun. Each heliostat is mounted to the platform with appropriate pivots, linkage, and controls to provide the additional positioning required to properly direct the solar radiation onto the receiver. The results are presented of the first phase of a study to investigate the technical and economic merits of a particular type of rotating field collector subsystem. The large pie-shaped platform would revolve over an array of support pedestals by means of a roller at the top of each pedestal. Several heliostats were built to demonstrate their construction features, and the operation of both flat and amphitheater rotating fields was studied. Work included an analysis of the concepts, development of modifications and additions to make the system comply with design criteria, and cost estimates to be used for comparison with other heliostat subsystems. Because of considerably high cost estimates, the focus of a large part of the study was directed toward developing lower cost designs of major components. (LEW)

Field evaluation of Bacillus thuringiensis H-14 against Aedes mosquitoes.  

PubMed

Studies were carried out on the residual efficacy of Bacillus thuringiensis H-14 (water dispersible granule, VectoBac ABG 6511) as direct application in the control of Aedes larvae in the field. Field Aedes sp populations in the earthen and glass jars were predetermined before initiation of the trial. On confirmation of the presence of Aedes species in the designated area, Sungai Nibong Kecil, Penang Island, Malaysia, Bti was introduced in the 55L earthen and 3L glass jars). Two test designs were carried out. The first design had treated water replenished daily with 6L of seasoned water and the second design is without the replenishment of water but evaporated water was replenished. Bti was effective in the field for at least 35 days with more than 80% reduction in the Aedes larvae in the treated containers. For earthen jars with daily replenishment of water, 100% reduction was recorded for the first 3 days, while more than 80% reduction was recorded up to day 40. At day 60, Bti still provided an efficacy of 54.32 +/- 4.61 (%) of reduction. Whilst for earthen jars without daily replenishment of water, 100% reduction was recorded for the first 5 days, while more than 80% of reduction was recorded up to day 40. For the glass jars studied, similar efficacy was observed. In jars with daily replenishment of water a better larval control was observed. Percentage of reduction from day 50 to 60 for replenishment of water was between 50 to 70% compared to without replenishment of water with less than 40%. PMID:17041550

Personal Radiation Detector Field Test and Evaluation Campaign  

SciTech Connect

Following the success of the Anole test of portable detection system, the U.S. Department of Homeland Security (DHS) Domestic Nuclear Detection Office organized a test and evaluation campaign for personal radiation detectors (PRDs), also known as 'Pagers'. This test, 'Bobcat', was conducted from July 17 to August 8, 2006, at the Nevada Test Site. The Bobcat test was designed to evaluate the performance of PRDs under various operational scenarios, such as pedestrian surveying, mobile surveying, cargo container screening, and pedestrian chokepoint monitoring. Under these testing scenarios, many operational characteristics of the PRDs, such as gamma and neutron sensitivities, positive detection and false alarm rates, response delay times, minimum detectable activities, and source localization errors, were analyzed. This paper will present the design, execution, and methodologies used to test this equipment for the DHS.

Field evaluation of antibiofouling compounds on optical instrumentation  

NASA Astrophysics Data System (ADS)

Biofouling has been a serious question in the stability of optical measurements in the ocean, particularly in moored and drifting buoy applications. Many investigators coat optical surfaces with various compounds to reduce the amount of fouling; to our knowledge, however, there are no objective, in-situ comparative testing of these compounds to evaluate their effectiveness with respect to optical stability relative to untreated controls. We have tested a wide range of compounds at in-situ locations in Halifax Harbor and in the Adriatic Sea on passive optical sensors. Compounds tested include a variety of TBT formulations, antifungal agents. and low-friction silicone-based compounds; time-scales of up to four months were evaluated. The results of these experiments are discussed.

Evaluation of residential exposure to intermediate frequency magnetic fields.  

PubMed

The authors measured the exposure to intermediate-frequency (IF: 10 kHz to 30 MHz) electromagnetic fields (EMF) in residential environments. They developed a system to acquire and record waveforms of IF magnetic fields (MFs) and set 5 nanotesla (nT) for the trigger level of acquisition. They operated the system near power lines, railroads, and electrical appliances as possible sources of IF-MFs. Most of the maximum values of magnetic flux density and the time derivative for each wave were below the upper limit of the measurable range of our system (i.e., 53 nT and 10 T/s); these values were much lower than the minimum amplitudes that can theoretically induce heating or membrane excitation within biological systems. Moreover, the amplitudes of the IF-MFs were not related to those of extremely low frequency (ELF) MF measured simultaneously, indicating that IF-MFs do not underlie the associations, observed in several epidemiological studies, between residential exposure to ELF-EMF and childhood cancer.

Evaluation and representation of two and three dimensional data fields from optical stream measurements  

NASA Astrophysics Data System (ADS)

The half automatic evaluation of interferograms is developed. A process for interpolation of interference order function between the edges of interference bands is achieved, which evaluates the intensity in the interferogram to improve the accuracy. Two different processes of quasi three dimensional representation of two dimensional scalar fields are implemented by means of color and a radiation model. For three dimensional scalar fields, a process is developed to obtain the tomographic data of stream fields. To allow an incresing of the image frequency by the representation of three dimensional scalar fields, more speed hardware is necessary, which is possible by a velocity optimization of the algorithm.

Development of a Visual Inspection Checklist for Evaluation of Fielded PV Module Condition (Presentation)  

SciTech Connect

A visual inspection checklist for the evaluation of fielded photovoltaic (PV) modules has been developed to facilitate collection of data describing the field performance of PV modules. The proposed inspection checklist consists of 14 sections, each documenting the appearance or properties of a part of the module. This tool has been evaluated through the inspection of over 60 PV modules produced by more than 20 manufacturers and fielded at two different sites for varying periods of time. Aggregated data from a single data collection tool such as this checklist has the potential to enable longitudinal studies of module condition over time, technology evolution, and field location for the enhancement of module reliability models.

Evaluations of carbon nanotube field emitters for electron microscopy  

NASA Astrophysics Data System (ADS)

Brightness of carbon nanotube (CNT) emitters was already reported elsewhere. However, brightness of electron emitter is affected by a virtual source size of the emitter, which strongly depends on electron optical configuration around the emitter. In this work, I- V characteristics and brightness of a CNT emitter are measured under a practical field emission electron gun (e-gun) configuration to investigate availability of CNT for electron microscopy. As a result, it is obtained that an emission area of MWNT is smaller than its tip surface area, and the emission area corresponds to a five-membered-ring with 2nd nearest six-membered-rings on the MWNT cap surface. Reduced brightness of MWNT is measured as at least 2.6×109 A/m 2 sr V. It is concluded that even a thick MWNT has enough brightness under a practical e-gun electrode configuration and suitable for electron microscopy.

Optical surface pressure measurements: Accuracy and application field evaluation  

NASA Astrophysics Data System (ADS)

Optical pressure measurement (OPM) is a new pressure measurement method rapidly developed in several aerodynamic research centers: TsAGI (Russia), Boeing, NASA, McDonnell Douglas (all USA), and DLR (Germany). Present level of OPM-method provides its practice as standard experimental method of aerodynamic investigations in definite application fields. Applications of OPM-method are determined mainly by its accuracy. The accuracy of OPM-method is determined by the errors of three following groups: (1) errors of the luminescent pressure sensor (LPS) itself, such as uncompensated temperature influence, photo degradation, temperature and pressure hysteresis, variation of the LPS parameters from point to point on the model surface, etc.; (2) errors of the measurement system, such as noise of the photodetector, nonlinearity and nonuniformity of the photodetector, time and temperature offsets, etc.; and (3) methodological errors, owing to displacement and deformation of the model in an airflow, a contamination of the model surface, scattering of the excitation and luminescent light from the model surface and test section walls, etc. OPM-method allows getting total error of measured pressure not less than 1 percent. This accuracy is enough to visualize the pressure field and allows determining total and distributed aerodynamic loads and solving some problems of local aerodynamic investigations at transonic and supersonic velocities. OPM is less effective at low subsonic velocities (M less than 0.4), and for precise measurements, for example, an airfoil optimization. Current limitations of the OPM-method are discussed on an example of the surface pressure measurements and calculations of the integral loads on the wings of canard-aircraft model. The pressure measurement system and data reduction methods used on these tests are also described.

Evaluation of arsine generation in arsenic field kit  

SciTech Connect

The recent outbreak of arsenic in groundwater of Bangladesh has prompted the widespread use of arsenic field kits. The kit involves the generation of arsine (AsH{sub 3}) from inorganic arsenic species by reduction with Zn and HCI. The arsine then reacts with a test strip containing HgBr{sub 2} to produce a color that is compared with a color scale for quantitation. It is known that arsine gas is one of the most toxic substances known to man. The objective of this work is to measure the concentration of ambient arsine produced during the test and suggest a safe handling procedure. The analytical method is based on integrated AsH{sub 3} measurement by a single-point arsine monitor. The method can be used to measure 4--50 ppb arsenic in water with 10% in precision and accuracy. Experiments show that a typical test kit produces arsine with a 90% efficiency. The concentration of arsine produced even at low level can be more than 9 times above the 50 ppbv threshold limiting value (TLV). Actual kit experiments show that 50% of the arsine escapes the reaction cell during the test. The authors estimate that the maximum arsine concentration in the immediate vicinity of the kit can be more than 35 times TLV of arsine from a single experiment with 100 ppb total arsenic in solution. Particularly, field workers performing a large number of tests in highly affected areas are exposed to a much higher level or arsine. They suggest that the tests should be performed in well-ventilated places and that the worker should be provided with a gas mask to minimize arsine inhalation.

Subjective preference evaluation of sound fields by performing singers  

NASA Astrophysics Data System (ADS)

A model of the auditory process is proposed for performing singers, which incorporates the added signal from bone conduction, as well as the psychological distance for subjective preference of the performer from the acoustic sound field of the stage. The explanatory power of previous scientific studies of vocal stage acoustics has been limited by a lack of an underlying theory of performer preference. Ando's theory, using the autocorrelation function (ACF) for parametrizing temporal factors, was applied to interpretation of singer sound field preference determined by the pair comparison method. Melisma style singing (no lyrics) was shown to increase the preferred delay time of reflections from a mean of 14 ms with lyrics to 23 ms without (p<0.05). The extent of the shift in preferred time delay was shown to be directly related to minima of the effective duration of the running ACF, (?e)min, calculated from each singer's voice. Voice matching experiments for singers demonstrated a strong overestimate of the voice outside the head compared with the singer's own voice (22.4 dB overestimate, p<0.01). Individual singer melisma singing delay preferences were compared for ``ah'' versus ``hum'' syllables, and the increased delay preference (41 ms) was shown to be correlated with (?e)min (r2<0.68, p<0.01). When the proposed bone conduction model was applied, using the measured overestimate of sound level of the singer's own voice for each singer (9.9 dB mean overestimate difference between ``ah'' and ``hum,'' p<0.01), the relationship of singer preference to (?e)min was improved (r2=0.97, p<0.01).

Field Evaluation of Seepage Meters in the Coastal Marine Environment  

NASA Astrophysics Data System (ADS)

The response of seepage meters was evaluated in a nearshore marine environment where water motion effects are more pronounced than in lake settings, where these meters have been used traditionally. Temporal and spatial variations of seepage, as well as potential artifacts, were evaluated using empty and 1000-ml pre-filled bag measurements. Time-series measurements confirmed earlier observations that anomalously high fluxes occur during the early stages (?10 min) of collection. As deployment times increased (30-60 min), measured flow rates stabilized at a level thought to represent the actual seepage flux. Pre-filling the plastic measurement bags effectively alleviated this anomalous, short-term influx. Reliable seepage measurements required deployment times sufficient to allow a net volume of at least 150 ml into the collection bag. Control experiments, designed by placing seepage meters inside sand-filled plastic swimming pools, served as indicators of external effects on these measurements, i.e. they served as seepage meter blanks. When winds were under 15 knots, little evidence was found that water motion caused artifacts in the seepage measurements. Tidal cycle influences on seepage rates were negligible in the present study area, but long-term temporal variations (weeks to months) proved substantial. Observed long-term changes in groundwater flux into the Gulf of Mexico correlated with water table elevation at a nearby monitoring well.

Field Evaluation of a Rapid Immunochromatographic Test for Tuberculosis  

PubMed Central

Rapid diagnostic tests for tuberculosis (TB) are needed to facilitate early treatment of TB and prevention of Mycobacterium tuberculosis transmission. The ICT Tuberculosis test is a rapid, card-based immunochromatographic test for detection of antibodies directed against M. tuberculosis antigens. The objective of the study was to evaluate the performance of the ICT Tuberculosis test for the diagnosis of active pulmonary TB (PTB) with whole blood, plasma, and serum from patients suspected of having PTB and from asymptomatic controls in a setting with a high prevalence of PTB. Seventy patients suspected of having PTB (and who were later confirmed to have or not to have PTB by use of M. tuberculosis culture as the “gold standard”) and 42 controls were studied. Twenty-one controls were neither vaccinated with Mycobacterium bovis bacillus Calmette-Guérin (BCG) nor tuberculin skin test (TST) positive (group A controls), and 21 controls were TST positive and/or had previously been vaccinated with BCG (group B controls). Study subjects were drawn from one hospital and one primary health care unit in Rio de Janeiro City, Brazil. One version of the test (ICT-1) was evaluated by using whole blood, plasma, and serum samples. Sera obtained for this study were frozen and later tested with a manufacturer-modified version of the test (ICT-2). Among the patients suspected of having PTB, the sensitivities of the ICT-1 with whole blood, serum, and plasma were 83, 65, and 70%, respectively, and the specificities were 46, 67, and 56%, respectively. Among the group A controls, the specificities of ICT-1 with the three specimen types were 95, 100, and 95%, respectively. Among the group B controls, the specificities of ICT-1 with the three specimen types were 71, 86, and 86%, respectively. Among the patients suspected of having PTB, the sensitivity of ICT-2 was 70% and the specificity was 65%. Among the group A controls, the specificity of ICT-2 was 95%, and among the group B controls, the specificity of ICT-2 was 81%. With a 29% observed prevalence of PTB among patients suspected of having PTB, the positive predictive values of the ICT tests ranged from 39 to 50% and the negative predictive values ranged from 82 to 87%. The ICT Tuberculosis tests were not sufficiently predictive to warrant their widespread use as routine diagnostic tests for PTB in this setting. However, further evaluation of these tests in specific epidemiologic settings may be warranted.

Field evaluation of polycarbonate versus conventional safety glasses.  

PubMed

Of all the causes of eye injury, gunshot has recently been cited as resulting in the highest rate of blindness and the lowest rate of visual recovery. Many of these cases are hunting accidents in which safety glasses could have prevented or lessened ocular damage. To evaluate the effectiveness of various types of safety glasses, we fired a Remington automatic shotgun at mannequin heads fitted with one of four types of safety lenses. From a distance of 10 yards, only polycarbonate lenses provided even partial protection. At 30 yards, polycarbonate and heat-treated lenses provided the best protection, whereas chemically treated and CR39 lenses provided significantly less protection. We recommend that hunters using shotguns in areas of poor visibility wear widely available polycarbonate safety glasses as well as "hunter's orange" to minimize their risk of devastating ocular gunshot injury.

DQE evaluation of a full-field digital mammography system  

NASA Astrophysics Data System (ADS)

Physical characteristics necessary to calculate the Detective Quantum Efficiency of a clinically used flat panel imager for full-breast digital mammography are presented. Objective quantities such as modulation transfer function (MTF), noise power spectrum (NPS) and detective quantum efficiency (DQE) have been evaluated. The X-ray photon fluence was determined using Half-Value-Layer (HVL) techniques. At an X-ray beam characterized by 28 kVp, Mo-anode and Mo filter as well as beam hardening by 5 cm Lucite, the detector is practically linear with x-ray exposure at least up to 33 mR. At an exposure of 33 mR and close to zero spatial frequency the DQE is in the vicinity of 60%.

Effect of prior performance on subsequent performance evaluation by field independent-dependent raters.  

PubMed

The importance of accurate performance appraisals is central to many aspects of personnel activities in organizations. This study examined threats due to past performance to accuracy of evaluation of subsequent performance by raters differing in scores on field dependence. 162 college students were classified as Field-dependent (n = 81) or Field-independent (n = 81), using a median split on the Group Embedded Figures Test. Past performance (a lecture) was good or poor, presented directly via a videotape or indirectly via a written evaluation to the Field-independent or Field-dependent groups. Analysis indicated the hypothesized contrast effect (ratings in the opposite direction from that of prior ratings) in the Direct condition and an unexpected, albeit smaller, contrast effect in the Indirect condition. There were also differential effects of performance, presentation, and field dependency on rating of lecturer's style and ability. PMID:18229539

Development of a Characterized Radiation Field for Evaluating Sensor Performance  

SciTech Connect

Numerous efforts are funded by US agencies (DOE, DoD, DHS) for development of novel radiation sensing and measurement systems. An effort has been undertaken to develop a flexible shielding system compatible with a variety of sources (beta, X-ray, gamma, and neutron) that can be highly characterized using conventional radiation detection and measurement systems. Sources available for use in this system include americium-beryllium (AmBe), plutonium-beryllium (PuBe), strontium-90 (Sr-90), californium-252 (Cf-252), krypton-85 (Kr-85), americium-241 (Am-241), and depleted uranium (DU). Shielding can be varied by utilization of materials that include lexan, water, oil, lead, and polyethylene. Arrangements and geometries of source(s) and shielding can produce symmetrical or asymmetrical radiation fields. The system has been developed to facilitate accurately repeatable configurations. Measurement positions are similarly capable of being accurately re-created. Stand-off measurement positions can be accurately re-established using differential global positioning system (GPS) navigation. Instruments used to characterize individual measurement locations include a variety of sodium iodide (NaI(Tl)) (3 x 3 inch, 4 x 4 x 16 inch, Fidler) and lithium iodide (LiI(Eu)) detectors (for use with multichannel analyzer software) and detectors for use with traditional hand held survey meters such as boron trifluoride (BF{sub 3}), helium-3 ({sup 3}He), and Geiger-Mueller (GM) tubes. Also available are Global Dosimetry thermoluminescent dosimeters (TLDs), CR39 neutron chips, and film badges. Data will be presented comparing measurement techniques with shielding/source configurations. The system is demonstrated to provide a highly functional process for comparison/characterization of various detector types relative to controllable radiation types and levels. Particular attention has been paid to use of neutron sources and measurements. (authors)

Evaluation of Cottonwood Creek field complex, Bighorn basin, Wyoming  

SciTech Connect

Most of the 83 million bbl of oil produced from Cottonwood Creek and associated fields (Worland, Rattlesnake, South Frisby) is from a suite of peritidal dolomite facies that were deposited in and on the flanks of an ancient estuarine system. Isopach and facies maps suggest that the Tensleep fault and related northwest-southeast-oriented basement fault blocks, controlled the formation of this estuary during Late Pennsylvanian/Early Permian time and the pattern of late Ervay deposition within the estuary. Upper Ervay pisolitic and algal-laminated units, along with intraclast grainstones, map as thick (40 to 90 ft), 1 to 2-mi wide and 2 to 5-mi long pods that represent a northwest-southeast peninsular system of islands. The thickest (i.e., central and highest) portions of these islands are made up of extensively altered pisolitic, brecciated units whose porosity systems were destroyed by aragonite and calcite cementation during periodically low sea level stands. The thinner margins of these island pods are made up of reservoir-quality peritidal fenestral fabric, algal-laminated units, and intraclast grainstones that were subjected to significantly less cementation because of less-frequent exposure. Permeability in these units may be enhanced by preferential fracturing because they were deposited along paleostructural zones of weakness. As a result of these depositional, diagenetic, and fracture patterns, cumulative production is commonly much higher (> 200,000 bbl/well) from the flank positions of these pods. Lagoonal dolomite mudstones and red-bed/evaporite sequences were deposited between and behind these islands, respectively, and form the major updip hydrocarbon seals.

Evaluation of the field relevance of several injury risk functions.  

PubMed

An evaluation of the four injury risk curves proposed in the NHTSA NCAP for estimating the risk of AIS>= 3 injuries to the head, neck, chest and AIS>=2 injury to the Knee-Thigh-Hip (KTH) complex has been conducted. The predicted injury risk to the four body regions based on driver dummy responses in over 300 frontal NCAP tests were compared against those to drivers involved in real-world crashes of similar severity as represented in the NASS. The results of the study show that the predicted injury risks to the head and chest were slightly below those in NASS, and the predicted risk for the knee-thigh-hip complex was substantially below that observed in the NASS. The predicted risk for the neck by the Nij curve was greater than the observed risk in NASS by an order of magnitude due to the Nij risk curve predicting a non-zero risk when Nij = 0. An alternative and published Nte risk curve produced a risk estimate consistent with the NASS estimate of neck injury. Similarly, an alternative and published chest injury risk curve produced a risk estimate that was within the bounds of the NASS estimates. No published risk curve for femur compressive load could be found that would give risk estimates consistent with the range of the NASS estimates. Additional work on developing a femur compressive load risk curve is recommended. PMID:21512903

Evaluating Attitudes towards Changes in Rural Landscape by Grazing Cattle on Abandoned Paddy Fields  

NASA Astrophysics Data System (ADS)

The appearance of cattle grazing abandoned paddy fields can be used to evaluate attitudes towards this land-use change. The semantic differential (SD) method was used families of a university student to evaluate and compare attitudes towards five types of rural landscape: pasture, pasture grazed by cattle, rice paddy field, abandoned paddy field converted to pasture and abandoned paddy field converted to pasture grazed by cattle. Cattle grazing abandoned paddy fields were determined to have a positive effect on the landscape. However, all grazing cattle created a negative attitude because of the unclean appearance of the landscape. Grazing cattle at high stocking rates in small areas could create a negative attitude because of the oppressive appearance of the landscape. The acceptance of grazing cattle was lower if the animals ware newly introduced to the landscape.

Mixed Waste Focus Area/Characterization Monitoring Sensor Technology Nondestructive Waste Assay Capability Evaluation Project End-User Summary Report  

SciTech Connect

The Mixed Waste Focus Area (MWFA) in conjunction with the Characterization Monitoring and Sensor Technology (CMST) crosscut program identified the need to objectively evaluate the capability of nondestructive waste assay (NDA) technologies. This was done because of a general lack of NDA technology performance data with respect to a representative cross section of waste form configurations comprising the Department of Energy (DOE) contact-handled alpha contaminated [e.g., transuranic (TRU) waste]. The overall objective of the Capability Evaluation Project (CEP) was to establish a known and unbiased NDA data and information base that can be used to support end-user decisions with regards to technology system selection and to support technology development organizations in identifying technology system deficiencies. The primary performance parameters evaluated in the CEP were measurement bias and relative precision. The performance of a given NDA technology is a direct function of the attributes represented by the waste matrix configuration. Such attributes include matrix density, matrix elemental composition, radionuclidic composition, radionuclide mass loading, and the spatial variation of these components. Analyzing the manner in which bias and precision vary as a function of test sample attribute and NDA technology provides a foundation for deriving performance capability and limitation statements and determines which waste matrix attributes, or combinations of attributes, are compatible or incompatible with existing technologies. The CEP achieved the stated end-user objective. The data indicate that the nondestructive waste assay systems evaluated have a definite capability to perform assay of contact-handled TRU waste packaged in 55-gallon drums. There is, however, a performance envelope where this capability exists, an area near the envelope boundaries where it is questionable, and a realm outside the envelope where the technologies do not perform. Therefore, the end user must be aware of this envelope and ensure the appropriate technology is selected. This program provides the end user with waste type specific performance data to assist in the assessment and selection of a given waste NDA technology. Additionally, the CEP afforded the private sector participants the opportunity to evaluate system performance using National Institute of Standards and Technology traceable radioactive significant enhancements to their respective systems and supported all participants in attaining DOE-CAO certification. Ultimately, the DOE end users will benefit from these enhancements.

The five 1985.0 main-field models and five 1990.0 main-field models that were proposed have been evaluated by comparing them with one another, with magnetic observatory data, and with Project MAGNET aerial survey data. The comparisons indicate that the main-field models proposed by IZMIRAN, and the secular-variation model proposed jointly by the British Geological Survey and the US Naval Oceanographic Office, should be assigned relatively lower weight in the derivation of the new IGRF models. -Author

Field to thermo-field to thermionic electron emission: A practical guide to evaluation and electron emission from arc cathodes  

NASA Astrophysics Data System (ADS)

This work is concerned with devising a method of evaluation of electron emission in the framework of the Murphy-Good theory, which would be as simple and computationally efficient as possible while being accurate in the full range of conditions of validity of the theory. The method relies on Padé approximants. A comparative study of electron emission from cathodes of arcs in ambient gas and vacuum arcs is performed with the use of this method. Electron emission from cathodes of arcs in ambient gas is of thermionic nature even for extremely high gas pressures characteristic of projection and automotive arc lamps and is adequately described by the Richardson-Schottky formula. The electron emission from vaporizing (hot) cathodes of vacuum arcs is of thermo-field nature and is adequately described by the Hantzsche fit formula. Since no analytical formulas are uniformly valid for field to thermo-field to thermionic emission, a numerical evaluation of the Murphy-Good formalism is inevitable in cases where a unified description of the full range of conditions is needed, as is the general case of plasma-cathode interaction in vacuum arcs, and the technique proposed in this work may be the method of choice to this end.

Field-based data collection techniques for the evaluation of information fusion systems  

NASA Astrophysics Data System (ADS)

In order to effectively evaluate information fusion systems or emerging technologies, it is critical to quickly, efficient, and accurately collect functional and observational data about such systems. One of the best ways to test a system's capabilities is to have an end user operate it in controlled but realistic field-based situations. Evaluation data of the systems' performance as well as observational data of the user's interactions can then be collected and analyzed. This analysis often gives insight into how the system may perform in the intended environment and of any potential areas for improvement. One common method for collection of this data involves an evaluator/observer generating hand-written notes, comments, and sketches. This often proves to be inefficient in complex sensor technology field-based evaluation environments. Personnel at the National Institute of Standards and Technology (NIST) have been tasked with collecting such evaluation data for emerging soldier-worn sensor systems. Lessons learned from the on-going development of efficient field-based evaluation data collection techniques will be discussed. The most recent evaluation data collection using a personal digital assistant (PDA)-style system and details of its use during an evaluation of a multi-team study will also be described.

Evaluation and Ranking of Geothermal Resources for Electrical Generation or Electrical Offset in Idaho, Montana, Oregon and Washington. Executive Summary.  

SciTech Connect

The objective was to consolidate and evaluate all geologic, environmental, legal, and institutional information in existing records and files, and to apply a uniform methodology to the evaluation and ranking of all known geothermal sites. This data base would enhance the making of credible forecasts of the supply of geothermal energy which could be available in the region over a 20 year planning horizon. The four states, working under a cooperative agreement, identified a total of 1265 potential geothermal sites. The 1265 sites were screened to eliminate those with little or no chance of providing either electrical generation and/or electrical offset. Two hundred and forty-five of the original 1265 sites were determined to warrant further study. On the basis of a developability index, 78 high temperature sites and 120 direct utilization sites were identified as having ''good'' or ''average'' potential for development and should be studied in detail. On the basis of cost, at least 29 of the high temperature sites appear to be technically capable of supporting a minimum total of at least 1000 MW of electrical generation which could be competitive with the busbar cost of conventional thermal generating technologies. Sixty direct utilization sites have a minimum total energy potential of 900+ MW and can be expected to provide substantial amounts of electrical offset at or below present conventional energy prices. Five direct utilization sites and eight high temperature sites were identified with both high development and economic potential. An additional 27 sites were shown to have superior economic characteristics, but development problems. 14 refs., 15 figs., 10 tabs.

Evaluation and Ranking of Geothermal Resources for Electrical Generation or Electrical Offset in Idaho, Montana, Oregon and Washington. Executive Summary  

SciTech Connect

In 1983, the Bonneville Power Administration contracted for an evaluation and ranking of all geothermal resource sites in the states of Idaho, Montana, Oregon, and Washington which have a potential for electrical generation and/or electrical offset through direct utilization of the resource. The objective of this program was to consolidate and evaluate all geologic, environmental, legal, and institutional information in existing records and files, and to apply a uniform methodology to the evaluation and ranking of all known geothermal sites. This data base would enhance the making of credible forecasts of the supply of geothermal energy which could be available in the region over a 20 year planning horizon. The four states, working together under a cooperative agreement, identified a total of 1,265 potential geothermal sites. The 1,265 sites were screened to eliminate those with little or no chance of providing either electrical generation and/or electrical offset. Two hundred and forty-five of the original 1,265 sites were determined to warrant further study. The Four-State team proceeded to develop a methodology which would rank the sites based upon an estimate of development potential and cost. Development potential was estimated through the use of weighted variables selected to approximate the attributes which a geothermal firm might consider in its selection of a site for exploration and possible development. Resource; engineering; and legal, institutional, and environmental factors were considered. Cost estimates for electrical generation and direct utilization sites were made using the computer programs CENTPLANT, WELLHEAD, and HEATPLAN. Finally, the sites were ranked utilizing a technique which allowed for the integration of development and cost information. On the basis of the developability index, 78 high temperature sites and 120 direct utilization sites were identified as having ''good'' or ''average'' potential for development and should be studied in detail. On the basis of cost, at least 29 of the high temperature sites appear to be technically capable of supporting a minimum total of at least 1,000 MW of electrical generation which could be competitive with the busbar cost of conventional thermal generating technologies. Sixty direct utilization sites have a minimum total energy potential of 900+ MW and can be expected to provide substantial amounts of electrical offset at or below present conventional energy prices. The combined development and economic rankings can be used to assist in determining sites with superior characteristics of both types. Five direct utilization sites and eight high temperature sites were identified with both high development and economic potential. An additional 27 sites were shown to have superior economic characteristics, but development problems. The procedure seems validated by the fact that two of the highest ranking direct utilization sites are ones that have already been developed--Boise, Idaho and Klamath Falls, Oregon. Most of the higher ranking high temperature sites have received serious examination in the past as likely power production candidates.

Development of a Visual Inspection Data Collection Tool for Evaluation of Fielded PV Module Condition  

SciTech Connect

A visual inspection data collection tool for the evaluation of fielded photovoltaic (PV) modules has been developed to facilitate describing the condition of PV modules with regard to field performance. The proposed data collection tool consists of 14 sections, each documenting the appearance or properties of a part of the module. This report instructs on how to use the collection tool and defines each attribute to ensure reliable and valid data collection. This tool has been evaluated through the inspection of over 60 PV modules produced by more than 20 manufacturers and fielded at two different sites for varying periods of time. Aggregated data from such a single data collection tool has the potential to enable longitudinal studies of module condition over time, technology evolution, and field location for the enhancement of module reliability models.

Economic evaluation of the Annual Cycle Energy System. Volume I. Executive summary. Final report. [In Minneapolis, Atlanta, and Philadelphia  

SciTech Connect

The objective of this study is to determine the energy effectiveness and the economic viability of the ACES concept. Three different classes of building are investigated, namely: single-family residence; multi-family residence; and commercial office building. The application of ACES to each of these building types is studied in three different climatic regions: Minneapolis, Atlanta, and Philadelphia. Computer programs - ACESIM for the residences and CACESS for the office building - were used, each comprised of four modules: loads; design; simulation; and economic. For each building type in each geographic location, the economic evaluation of the ACES is based on a comparison of the present worth of the ACES to the present worth of a number of conventional systems. The results of this analysis indicate that the economic viability of the ACES is very sensitive to the assumed value of the property tax, maintenace cost, and fuel-escalation rates, while it is relatively insensitive to the assumed values of other parameters. Fortunately, any conceivable change in the fuel-escalation rates would tend to increase the viability of the ACES concept. An increase in the assumed value of the maintenance cost or property tax would tend to make the ACES concept less viable; a decrease in either would tend to make the ACES concept more viable. The detailed results of this analysis are given in Section 5.4 of Volume II. 2 figures, 21 tables.

National Uranium Resource Evaluation. Volume 1. Summary of the geology and uranium potential of Precambrian conglomerates in southeastern Wyoming  

SciTech Connect

A series of uranium-, thorium-, and gold-bearing conglomerates in Late Archean and Early Proterozoic metasedimentary rocks have been discovered in southern Wyoming. The mineral deposits were found by applying the time and strata bound model for the origin of uranium-bearing quartz-pebble conglomerates to favorable rock types within a geologic terrane known from prior regional mapping. No mineral deposits have been discovered that are of current (1981) economic interest, but preliminary resource estimates indicate that over 3418 tons of uranium and over 1996 tons of thorium are present in the Medicine Bow Mountains and that over 440 tons of uranium and 6350 tons of thorium are present in Sierra Madre. Sampling has been inadequate to determine gold resources. High grade uranium deposits have not been detected by work to date but local beds of uranium-bearing conglomerate contain as much as 1380 ppM uranium over a thickness of 0.65 meters. This project has involved geologic mapping at scales from 1/6000 to 1/50,000 detailed sampling, and the evaluation of 48 diamond drill holes, but the area is too large to fully establish the economic potential with the present information. This first volume summarizes the geologic setting and geologic and geochemical characteristics of the uranium-bearing conglomerates. Volume 2 contains supporting geochemical data, lithologic logs from 48 drill holes in Precambrian rocks, and drill site geologic maps and cross-sections from most of the holes. Volume 3 is a geostatistical resource estimate of uranium and thorium in quartz-pebble conglomerates.

Clinical user evaluation of field dental equipment under military deployment conditions.  

PubMed

The purpose of this work was to evaluate the clinical performance of a number of types of field (i.e., portable) dental equipment used under actual military deployment conditions. This equipment is often used under demanding field conditions where temperature, humidity, and air quality are not controlled. This article presents the results of a project conducted by the Naval Institute for Dental and Biomedical Research and the Air Force Dental Evaluation and Consultation Service to evaluate commercially available field dental equipment through laboratory testing and clinical user evaluations at military deployment sites. The purpose of the study was to identify the best-performing and most cost-effective field dental equipment for possible operational use by the U.S. Navy. Initial laboratory testing was performed at the Naval Institute for Dental and Biomedical Research and the equipment was then shipped to Okinawa, Japan, where it was tested by military dentists and assistants under deployment conditions. The testing provided beneficial results by identifying equipment that performed properly and equipment that exhibited shortcomings serious enough to render it inappropriate for field use.

Protein release from yeast cells as an evaluation method of physical effects in ultrasonic field.  

PubMed

The release rate of intercellular protein from yeast cells by the ultrasonic action is proposed as a method for evaluating the physical (mechanical) effects of the ultrasonic field. The protein concentration was quantitatively determined using UV absorbance of proteins by spectrophotometry. The detail of the procedures, such as the effects of the origin of yeast cells, pretreatment of the cells, and the wavelengths for spectrophotometric determination of protein content, are examined. The effectiveness of the proposed evaluation method was experimentally demonstrated by changing the irradiation conditions of ultrasound, such as the concentration of yeast cells, temperature, ultrasound power, types of sonicator, and the superposition with the mechanical mixing. The results validate the usefulness of the proposed evaluation method for the quantification of the physical effects of ultrasound fields. Also, the range of cavitational effects of ultrasound sensed by the evaluation procedures were discussed. PMID:18424218

Evaluation of Bull Trout Movements in the Tucannon and Lower Snake Rivers, 2002-2006 Project Completion Summary.  

SciTech Connect

The Columbia River Distinct Population Segment of bull trout (Salvelinus confluentus) was listed as threatened under the Endangered Species Act in 1998. One of the identified major threats to the species is fragmentation resulting from dams on over-wintering habitats of migratory subpopulations. A migratory subgroup in the Tucannon River appeared to utilize the Snake River reservoirs for adult rearing on a seasonal basis. As a result, a radio telemetry study was conducted on this subgroup from 2002-2006, to help meet Reasonable and Prudent Measures, and Conservation Recommendations associated with the lower Snake River dams in the FCRPS Biological Opinion, and to increase understanding of bull trout movements within the Tucannon River drainage. We sampled 1,109 bull trout in the Tucannon River; 124 of these were surgically implanted with radio tags and PIT tagged, and 681 were only PIT tagged. The remaining 304 fish were either recaptures, or released unmarked. Bull trout seasonal movements within the Tucannon River were similar to those described for other migratory bull trout populations. Bull trout migrated upstream in spring and early summer to the spawning areas in upper portions of the Tucannon River watershed. They quickly moved off the spawning areas in the fall, and either held or continued a slower migration downstream through the winter until early the following spring. During late fall and winter, bull trout were distributed in the lower half of the Tucannon River basin, down to and including the mainstem Snake River below Little Goose Dam. We were unable to adequately radio track bull trout in the Snake River and evaluate their movements or interactions with the federal hydroelectric dams for the following reasons: (1) none of our radio-tagged fish were detected attempting to pass a Snake River dam, (2) our radio tags had poor transmission capability at depths greater than 12.2 m, and (3) the sample size of fish that actually entered the Snake River was small (n=6). In spite of this project's shortcomings, bull trout continue to be observed in low numbers at Snake River dam fish facilities. It is highly possible that bull trout observed at the Snake River dam fish facilities are originating from sources other than the Tucannon River. We suggest that these fish might come from upstream sources like the Clearwater or Salmon rivers in Idaho, and are simply following the outmigration of juvenile anadromous fish (a food supply) as they emigrate toward the Pacific Ocean. Based on our study results, we recommend abandoning radio telemetry as a tool to monitor bull trout movements in the mainstem Snake River. We do recommend continuing PIT tagging and tag interrogation activities to help determine the origin of bull trout using the Snake River hydropower facilities. As a complementary approach, we also suggest the use of genetic assignment tests to help determine the origin of these fish. Lastly, several recommendations are included in the report to help manage and recover bull trout in the Tucannon subbasin.

Evaluation of Breast Sentinel Lymph Node Coverage by Standard Radiation Therapy Fields  

SciTech Connect

Background: Biopsy of the breast sentinel lymph node (SLN) is now a standard staging procedure for early-stage invasive breast cancer. The anatomic location of the breast SLN and its relationship to standard radiation fields has not been described. Methods and Materials: A retrospective review of radiotherapy treatment planning data sets was performed in patients with breast cancer who had undergone SLN biopsy, and those with a surgical clip at the SLN biopsy site were identified. The location of the clip was evaluated relative to vertebral body level on an anterior-posterior digitally reconstructed radiograph, treated whole-breast tangential radiation fields, and standard axillary fields in 106 data sets meeting these criteria. Results: The breast SLN varied in vertebral body level position, ranging from T2 to T7 but most commonly opposite T4. The SLN clip was located below the base of the clavicle in 90%, and hence would be excluded from standard axillary radiotherapy fields where the inferior border is placed at this level. The clip was within the irradiated whole-breast tangent fields in 78%, beneath the superior-posterior corner multileaf collimators in 12%, and outside the tangent field borders in 10%. Conclusions: Standard axillary fields do not encompass the lymph nodes at highest risk of containing tumor in breast cancer patients. Elimination of the superior-posterior corner MLCs from the tangent field design would result in inclusion of the breast SLN in 90% of patients treated with standard whole-breast irradiation.

The effects of small field dosimetry on the biological models used in evaluating IMRT dose distributions  

NASA Astrophysics Data System (ADS)

The primary goal in radiation oncology is to deliver lethal radiation doses to tumors, while minimizing dose to normal tissue. IMRT has the capability to increase the dose to the targets and decrease the dose to normal tissue, increasing local control, decrease toxicity and allow for effective dose escalation. This advanced technology does present complex dose distributions that are not easily verified. Furthermore, the dose inhomogeneity caused by non-uniform dose distributions seen in IMRT treatments has caused the development of biological models attempting to characterize the dose-volume effect in the response of organized tissues to radiation. Dosimetry of small fields can be quite challenging when measuring dose distributions for high-energy X-ray beams used in IMRT. The proper modeling of these small field distributions is essential in reproducing accurate dose for IMRT. This evaluation was conducted to quantify the effects of small field dosimetry on IMRT plan dose distributions and the effects on four biological model parameters. The four biological models evaluated were: (1) the generalized Equivalent Uniform Dose (gEUD), (2) the Tumor Control Probability (TCP), (3) the Normal Tissue Complication Probability (NTCP) and (4) the Probability of uncomplicated Tumor Control (P+). These models are used to estimate local control, survival, complications and uncomplicated tumor control. This investigation compares three distinct small field dose algorithms. Dose algorithms were created using film, small ion chamber, and a combination of ion chamber measurements and small field fitting parameters. Due to the nature of uncertainties in small field dosimetry and the dependence of biological models on dose volume information, this examination quantifies the effects of small field dosimetry techniques on radiobiological models and recommends pathways to reduce the errors in using these models to evaluate IMRT dose distributions. This study demonstrates the importance of valid physical dose modeling prior to the use of biological modeling. The success of using biological function data, such as hypoxia, in clinical IMRT planning will greatly benefit from the results of this study.

Evaluation of interactions of electric fields due to electrostatic discharge with human tissue.  

PubMed

Electrostatic discharges (ESDs) produce in the human tissue very strong electric fields of short duration. Possible biophysical interactions are evaluated by comparing the fields in subcutaneous fat/skin to the thresholds for peripheral nerve stimulation, and by computations of membrane potential and electric fields in cytoplasm of a typical cell in bone marrow. It is found that a 4-A peak ESD event is capable of stimulation of nerves located in subcutaneous fat of the lower arm of the hand eliciting a spark, with tens of kV/m and pulse duration of approximately 80 ns. For the same ESD event, the transmembrane potential (TMP) reaches 32 mV with a pulse duration of approximately 200 ns (half-width duration). The electric field in the cytoplasm of a bone marrow cell changes from about 8.8 kV/m to--2 kV/m in about 200 ns. PMID:15605868

Laboratory studies and a second field evaluation have been completed to assess the performance of the Semi-Volatile Organic Sampling Train (Semi-VOST) method for measuring concentrations of principal organic hazardous constituents (POHCs) with boiling points greater than 100/sup 0/C emitted from hazardous-waste incineration. The Semi-VOST methodology was tested initially through a series of laboratory experiments and a field test at a hazardous waste incinerator. In the first field-test method precision and bias were shown to be compound specific. The second field test was performed at a hazardous-waste incinerator using five gaseous deuterated compounds to dynamically spike four simultaneously operating Semi-VOST trains. Toluene, 1,1,2,2-tetrachloroethane, and chlorobenzene were chosen because of boiling point and chemical functionality.

Evaluating the applicability of the finite element method for modelling of geoelectric fields  

NASA Astrophysics Data System (ADS)

Geomagnetically induced currents in power systems are due to space weather events which create geomagnetic disturbances accompanied by electric fields at the surface of the Earth. The purpose of this paper is to evaluate the use of the finite element method (FEM) to calculate the magnetic and electric fields to which long transmission lines of power systems on the Earth are exposed. The well-known technique of FEM is used for the first time to simulate magnetic and electric fields applicable to power systems. Several test cases are modelled and compared with known solutions. It is shown that FEM is an effective modelling technique that can be applied to determine the electric fields which affect power systems. FEM enables an increased capability beyond the traditional methods for modelling electric and magnetic fields with layered earth conductivity structures, as spatially more complex structures can be considered using FEM. As an example results are presented for induction, due to a line current source, in adjacent regions with different layered conductivity structures. The results show the electric field away from the interface is the same as calculated for a single region; however near the interface the electric field is influenced by both regions.

Preliminary technical and legal evaluation of disposing of nonhazardous oil field waste into salt caverns  

SciTech Connect

Caverns can be readily formed in salt formations through solution mining. The caverns may be formed incidentally, as a result of salt recovery, or intentionally to create an underground chamber that can be used for storing hydrocarbon products or compressed air or disposing of wastes. The purpose of this report is to evaluate the feasibility, suitability, and legality of disposing of nonhazardous oil and gas exploration, development, and production wastes (hereafter referred to as oil field wastes, unless otherwise noted) in salt caverns. Chapter 2 provides background information on: types and locations of US subsurface salt deposits; basic solution mining techniques used to create caverns; and ways in which salt caverns are used. Later chapters provide discussion of: federal and state regulatory requirements concerning disposal of oil field waste, including which wastes are considered eligible for cavern disposal; waste streams that are considered to be oil field waste; and an evaluation of technical issues concerning the suitability of using salt caverns for disposing of oil field waste. Separate chapters present: types of oil field wastes suitable for cavern disposal; cavern design and location; disposal operations; and closure and remediation. This report does not suggest specific numerical limits for such factors or variables as distance to neighboring activities, depths for casings, pressure testing, or size and shape of cavern. The intent is to raise issues and general approaches that will contribute to the growing body of information on this subject.

Evaluation of near-field thermal environmental conditions for a spent fuel repository in tuff  

SciTech Connect

A repository heat transfer analysis is being performed by the Pacific Northwest Laboratory (PNL) for the US Department of Energy`s Performance Assessment Scientific Support Program. The objective of this ongoing study is to evaluate near-field host rock and waste package surface temperatures for a spent fuel repository system located in a tuff geologic medium. A spent fuel logistics model of the waste management system was used to evaluate the thermal characteristics of spent fuel emplaced in the repository. A three-dimensional heat conduction model of the underground repository facility was used to evaluate near-field host rock temperatures throughout the 10,000-year isolation period. The spent-fuel thermal characteristics and near-field host rock temperatures were then used to estimate waste package surface temperature histories and distributions for the repository system. The resulting temporal and spacial distributions provide key input to repository source term model evaluations of waste isolation performance. 15 refs., 7 figs., 1 tab.

Evaluating GIS for establishing and monitoring environmental conditions of oil fields  

SciTech Connect

Good management of an oil field and compliance with ever-increasing environmental regulations is enhanced by technologies that improve a company`s understanding of field/production facilities and environmental conditions that have occurred to both through time. In Nigeria, Kazakhstan, Indonesia, and offshore Cabinda, remote sensing, computer-aided drafting (CAD) and Global Positioning System (GPF) technologies have effectively been used by Chevron to provide accurate maps of facilities and to better understand environmental conditions. Together these proven technologies have provided a solid and cost-effective base for planning field operation, verifying well and seismic locations, and locating sampling sites. The end product of these technologies is often locations, and locating sampling sites. The end product of these technologies is often cartographic-quality hardcopy images and maps for use in the office and field. Chevron has been evaluating the capability of Geographical Information System (GIS) technology to integrate images, maps, and tabular data into a useful database that can help managers and workers better evaluate conditions in an oil field, plan new facilities, and monitor/predict trends (for example, of air emissions, groundwater, soil chemistry, subsidence, etc.). Remote sensing, CAD (if formatted properly), and GPS data can be integrated to establish the spatial or cartographic base of the GIS. A major obstacle to establishing a sophisticated GIS for an overseas operation is the initial cost of data collection and conversion from legacy data base management systems and hardcopy to appropriate digital format. However, Chevron routinely uses GIS for oil spill modeling and is now using GIS in the field for integrating GPS data with field observations and programs.

Executive Summary

Motivation Our country faces profound challenges that must be addressed in order to ensure our continued freedom and security. As the September 11, 2001, attacks on the Pentagon and World Trade Center illustrate, threats to the United States are present within our borders. On that day, after at least 20 months of planning and preparation, nineteen terrorists hijacked four airliners at three different airports in a coordinated attack. The hijackers crashed two planes into the World Trade Center’s twin towers and one plane into the Pentagon. The fourth plane, intended to attack another U.S. landmark, crashed in a field in Pennsylvania. 2973 people lost their lives as a result of this attack. As the attack unfolded, government agencies and emergency response personnel had to respond in real time to situations for which policies and procedures did not exist. They were forced to assess situations and make decisions under extreme pressure, often without having critical information that would help them save additional lives.

Evaluation of the electrostatic field strength at the site of exocytosis in adrenal chromaffin cells.  

PubMed Central

Exocytosis in secretory cells consists of release from intracellular storage granules directly into the extracellular space via fusion of the granule membrane with the plasma membrane of the cell. It is considered here as comprising two distinct processes. One is the close apposition of granule and plasma membranes. The other arises from interactions between the two membranes during the process of apposition, leading to the formation of a fusion pore. In the following it is shown for the case of the adrenal medullary chromaffin cell that the fusion pore can be ascribed to electroporation of the granule membrane, triggered by the strong electric field existing at the site of exocytosis. Based on an electric surface charge model of the cytoplasmic side of the plasma membrane, resulting from the negatively charged phosphatidylserine groups, it is found that the electrostatic field strength at the site of exocytosis reaches values on the order of 10(8) V/m at small intermembrane distances of 3 nm and lower. The field strength increases with the size of the disc-shaped plasma membrane region generating the electric field, reaching an approximate limit for a radius of 10 nm, at a surface charge density of 5.4 x 10(-2) C/m2. According to previous experimental evaluations of threshold field strength, this field is sufficiently strong to cause membrane electroporation. This step is a precondition for the subsequent membrane fusion during the ongoing process of apposition, leading to secretion.

Definitive magnetic reference field (DGRF) evaluation based on marine magnetic anomalies  

NASA Astrophysics Data System (ADS)

When compiling magnetic data that have been collected over several decades, the accuracy of the magnetic reference fields that are used to reduce the data to a common datum-level becomes an important factor. Definitive magnetic reference fields have been defined at 5-year intervals. In this study we evaluated these reference fields by applying them to marine magnetic data that have been collected off the Canadian east coast in the period 1963-1984. For 35-50° N, the anomalies for the period 1970-1975 were found to be ~ 50 nT higher than those obtained in other periods. A cross-over analysis performed on the whole data set yielded ~ 60 000 cross points and confirmed these results. As the source of the anomalies are unvarying, we conclude from these observations that the magnetic reference fields in this part of the world do not accurately correct for the time-varying component of the magnetic field. This has serious consequences for magnetic data compilations; when not treated in a generally accepted fashion, these inaccuracies could lead to user-defined corrections to the reference fields, which would be a step in the wrong direction.

A field bioassay evaluating candidate chemicals as aerial repellents was developed and evaluated against natural mosquito populations in Beltsville, MD. The bioassay consisted of an attractive source surrounded by a grid of 16 septa containing a volatile candidate aerial repellent, compared with an attractive source without such a grid. The attractive source was a Centers for Disease Control and Prevention light trap supplemented with carbon dioxide. Significant sources of variation included weather, position, and the differential response of mosquito species. Despite these sources of variation, significant repellent responses were obtained for catnip oil, E,Z-dihydronepetalactone, and DEET. PMID:23393752

[Quantitative evaluation of cavitation bubble fields induced by lithotripter shock waves].  

PubMed

Extracorporeal shock wave lithotripsy is the world-wide standard therapy for renal stones. The rare-faction phase of the shock wave can induce cavitation within the body. Cavitation contributes to stone disintegration but also to medical side effects. The aim of this study was to evaluate the spatial and size distribution of the cavitation bubble fields. To this end, the bubble fields were photographed digitally and evaluated automatically by image processing. The influence of various medium (water) and shock wave parameters was investigated. Water purity, i.e. the number of cavitation nuclei, was the most critical medium parameter which has to be controlled. At oxygen levels higher than 4 mg/l, cavitation increased rapidly when high shock wave frequencies of 2 Hz were used. PMID:12465304

Following reports of suspected gastrointestinal strongylid nematode resistance to thiophanate in sheep and goats at Sokoine University of Agriculture (SUA), Tanzania, field strains of Haemonchus contortus, one from SUA and another from Kimamba, Tanzania, were selected for a critical controlled test to evaluate the efficacy of thiophanate. The SUA H. contortus strain in goats showed a marked resistance to thiophanate at an oral dose of 50 mg kg-1 liveweight (efficacy = 24.1%), while the Kimamba H. contortus strain showed very marked susceptibility (efficacy = 99.7%) to thiophanate at the same oral dose. This is the first report from East Africa of a field strain of H. contortus resistant to thiophanate. The incidence of resistant strains of strongyloid parasites to benzimidazole anthelmintics in sheep and goats in East Africa is on the increase. The magnitude of this problem should be evaluated and remedial solutions sought. PMID:2382387

Evaluation of the effects of electric fields on implanted cardiac pacemakers. Final report  

SciTech Connect

The effects of extra high voltage (EHV) transmission line electric fields on pacemaker function were evaluated in 11 patients with seven different implanted pacemaker models from four manufacturers. Alteration in pacemaker function was demonstrated in five unipolar units (three different models) from two manufacturers during exposure to electric fields ranging from 2 to 9 kV/m, with total body currents from 47 to 175 ..mu..A. These electric fields and body currents are representative of values that can be encountered by individuals standing beneath EHV transmission lines. Transient alterations in pacemaker function observed in this study included inappropriate triggered activity, inhibition of impulse generation, reduction in rate, and reversion from demand to asynchronous mode. Electromagnetic interference from high voltage transmission lines can induce alterations in pacemaker function in certain designs of these devices. However, pacemaker manufacturers can incorporate appropriate circuits in the pacemaker design to eliminate this problem. 8 references.
