NBS (National Bureau of Standards): Materials measurements  

NASA Technical Reports Server (NTRS)

Work in support of NASA's Microgravity Science and Applications Program is described. The results of the following three tasks are given in detail: (1) surface tensions and their variations with temperature and impurities; (2) convection during unidirectional solidification; and (3) measurement of high temperature thermophysical properties. Tasks 1 and 2 were directed toward determining how the reduced gravity obtained in space flight can affect convection and solidification processes. Emphasis in task 3 was on development of levitation and containerless processing techniques which can be applied in space flight to provide thermodynamic measurements of reactive materials.

Seventy Years of Radio Science, Technology, Standards, and Measurement at the National Bureau of Standards  

NASA Astrophysics Data System (ADS)

This large volume describes all the forms of radio research done at the National Bureau of Standards (now, National Institute of Standards and Technology) from its founding in 1901 until about 1980. The volume truly reflects its subtitle; it describes in great detail research in radio propagation and all its connections with geophysics and geospace, but also radio as instrument for discovery and application in meteorology, navigation, and in standards of measurement and testing in electronics.The book is a bit unwieldy and some of its chapters will be of most interest to former NBS employees. For example, there is a lengthy chapter on the transfer of radio research work from Washington, D.C, to Boulder, Colo., in the early 1950s, complete with photostat of the quit claim deed to NBS from the Boulder Chamber of Commerce. On the other hand, radio research developed and flourished in this country in the early days at industrial (Bell Telephone, General Electric, Westinghouse) and government (NBS, Naval Research Laboratory) labs more than in academia, and it is very interesting to learn how the labs interacted and to read details of the organizational structure. I can attest personally to the great difficulties in locating materials concerning radio history. While we have numerous volumes devoted to certain popular radio heroes, little is available concerning government radio pioneers such as L. W. Austin, who directed the U.S. Navy's radio research for many years while situated physically at the Bureau of Standards, or J. H. Dellinger, long-time chief of the Radio Section and head spokesman on radio for the U.S. government until the 1930s.

Challenges in Evaluating All-Cause Hospital Readmission Measures for Use as National Consensus Standards  

PubMed Central

Context: The National Quality Forum (NQF) aims to improve the quality of health care for all Americans through fulfillment of its three-part mission. The NQF uses its formal Consensus Development Process to evaluate and endorse consensus standards, including performance measures, best practices, frameworks, and reporting guidelines. Objective: To understand the opportunities and challenges in endorsing measures addressing all-cause readmissions to hospitals for use as national voluntary consensus standards for accountability and quality-improvement purposes. Design: Report of standards development process. Main Outcome Measures: The Consensus Development Process was used to evaluate 3 candidate standards using the NQF Measure Evaluation Criteria. A 21-member steering committee rated each standard according to the criteria and made initial endorsement recommendations for all measures. Results: Through the evaluation of measures for endorsement, several overarching issues in measuring all-cause readmissions were identified, including statistical modeling and the usability of the measures for quality improvement and accountability. Additionally, it was decided that, for the first time, quality monitoring and accountability of readmissions will take place at the health-plan level. Measuring at various levels of accountability reinforces the idea that multiple stakeholders have a responsibility and a role to reduce readmissions. Conclusions: These NQF-endorsed measures are a major step in promoting better understanding of readmissions and a reduction in hospital readmission rates, when appropriate. These measures can help reduce the substantial financial and emotional stress that readmissions place on the health care system, and patients will be able to communicate hospital-level performance on this important quality indicator.

Measurement of the French national tritiated-water standard by helium-3 mass spectrometry.  

PubMed

The (3)He ingrowth technique is based on the detection of the tritium radioactive daughter, (3)He, by mass spectrometry. Over the last three decades it has been used extensively in oceanography and groundwater studies for measurements of very low to ultra-low levels of tritium. To compare it with the best available methods of radioactive counting, we applied this method to measure the massic activity of a tritiated-water primary standard prepared by the French Laboratoire National Henri Becquerel (LNHB). One liter of a low-level tritium solution was prepared from a small aliquot of the LNHB standard by two-step gravimetric dilution with tritium-free groundwater. Sixteen samples of this solution were analyzed at the LSCE-Saclay noble gas facility, using the (3)He ingrowth method. The massic activity of the prepared solution was also measured by Liquid Scintillation Counting using the Quantulus LNHB counter and an internal calibration method with the LNHB tritiated water standard. All results agree within their standard uncertainty. PMID:24373872

Requirements relating to radon in the International Basic Safety Standards: information, measurement and national strategies.  

PubMed

The fifth edition of the International Basic Safety Standards (BSS) has recently been established as Part 3 of the General Safety Requirements of the IAEA Safety Standards Series. The BSS applies to all exposure situations and to all categories of exposure. As such, the BSS addresses both occupational exposure due to radon in workplaces and public exposure due to radon in dwellings. In workplaces, exposure due to radon is treated either as a planned exposure situation or as an existing exposure situation, depending on the circumstances. With regard to exposure due to radon in dwellings, the BSS requires that general information on radon, including information on health risks and the synergy with smoking, be made available to the public and other interested parties. Countries are also required to determine whether an action plan for controlling exposure due to radon indoors is necessary, and, if so, to establish and implement such an action plan. Guidance material, covering the establishment of reference levels, national and regional radon surveys, identification of radon prone areas, building codes for new buildings, corrective actions for existing buildings, information campaigns and programme evaluation and effectiveness is currently being developed.

COOMET regional comparison of national measurement standards of air kerma for 137Cs ? radiation at protection level  

NASA Astrophysics Data System (ADS)

Results are presented of the COOMET supplementary comparison of the national measurement standards for air kerma in 137Cs ? radiation at protection level (~10 mGy/h). Ten National Metrology Institutes from the COOMET organization and the International Atomic Energy Agency participated in this COOMET project no. 445. The PTB acted as pilot laboratory. Two of the participants, the SMU (Slovakia) and the NSC-'IM' (Ukraine) participated in the measurements but did not submit a valid report of results. The comparison reference value (CRV) was obtained as the mean result of the PTB and the VNIIM, both of which had previously taken part in the key comparison BIPM-RI(I)-K5. The degree of equivalence with the CRV was evaluated. The results were consistent within the relative standard uncertainties of the comparison ranging from 0.28% to 1.3% and deviated from the CRV by less than 1%. Main text. To reach the main text of this paper, click on Final Report. Note that this text is that which appears in Appendix B of the BIPM key comparison database kcdb.bipm.org/.

The Brazilian National Standards in Acoustics  

NASA Astrophysics Data System (ADS)

The elaboration of technical standards is a difficult and expensive activity, not always necessary, since there are international standards that can be used. Therefore, the elaboration of technical standards in Brazil is, in general, linked to several programs and regulations developed in this country. Among these are the Brazilian labeling program, which intends to label domestic appliances; the approval of new car models and the annual control of the existent fleet; occupational noise control programs and the growing requirement for the accreditation of calibration and testing laboratories. In particular, in the electroacoustics area, in 1998 a Technical Committee formed of 3 Working Groups was created, which developed 11 technical standard projects relating to specific programs in the process or in the elaboration phase such as the introduction of the conformity tests for equipment used for acoustic measurements, the creation of a conformity label for audio equipment, and an intercomparision program at the national level for the calibration of audiometers. This contribution aims to show a general vision of the state of the art of Brazilian standardization as well as the several programs for which these standards will serve as support.

Coordinate Standard Measurement Development  

SciTech Connect

A Shelton Precision Interferometer Base, which is used for calibration of coordinate standards, was improved through hardware replacement, software geometry error correction, and reduction of vibration effects. Substantial increases in resolution and reliability, as well as reduction in sampling time, were achieved through hardware replacement; vibration effects were reduced substantially through modification of the machine component dampening and software routines; and the majority of the machine's geometry error was corrected through software geometry error correction. Because of these modifications, the uncertainty of coordinate standards calibrated on this device has been reduced dramatically.

National Patterns of Risk-Standardized Mortality and Readmission for Acute Myocardial Infarction and Heart Failure: Update on Publicly Reported Outcomes Measures Based on the 2010 Release  

PubMed Central

Background Patient outcomes provide a critical perspective on quality of care. The Centers for Medicare and Medicaid Services (CMS) is publicly-reporting 30-day risk-standardized mortality rates (RSMRs) and risk-standardized readmission rates (RSRRs) for patients hospitalized with acute myocardial infarction (AMI) and heart failure (HF). We provide a national perspective on hospital performance for the 2010 release of these measures. Methods and Results The RSMRs and RSRRs are calculated from Medicare claims data for fee-for-service Medicare beneficiaries, 65 years or older, hospitalized with AMI or HF between July 1, 2006 and June 30, 2009. The rates are calculated using hierarchical logistic modeling to account for patient clustering, and are risk-adjusted for age, sex and patient comorbidities. The median RSMR for AMI was 16.0% and for HF was 10.8%. Both measures had a wide range of hospital performance with an absolute 5.2% difference between hospitals in the 5th versus 95th percentile for AMI and 5.0% for HF. The median RSRR for AMI was 19.9%, and for HF was 24.5% (3.9% range for 5–95th percentile for AMI, 6.7% for HF). Distinct regional patterns were evident for both measures and both conditions. Conclusions High RSRRs persist for AMI and HF and clinically meaningful variation exists for RSMRs and RSRRs for both conditions. Our results suggest continued opportunities for improvement in patient outcomes for HF and AMI.

The definition of the standards are applicable in principle to the calibration and use of nonstandardized throttling devices, such as the venturi tube. The standards are valid, likewise, as a basis for discharge measurements in the German acceptance standards.

Activities of NIST (National Inst. of Standards and Technology)  

NASA Technical Reports Server (NTRS)

The Radiometric Physics Division of the NIST is responsible for the national standards in radiation thermometry, spectroradiometry, photometry, and spectrophotometry; dissemination of these standards by providing measurement services to customers requiring calibrations of the highest accuracy; and conducting fundamental and applied research to develop the scientific basis for future measurement services. Its relevance to EOS/TIR calibration includes calibrating unknown blackbody for radiance using a well-characterized NIST blackbody source by matching the radiant fluxes with an IR radiometer. The TIR Round Robin is used to verify the calibration of the sources that are used for the absolute radiometric calibration of the individual EOS sensors.

Development of Hydrocarbon Flow Calibration Facility as a National Standard  

NASA Astrophysics Data System (ADS)

A new primary standard for hydrocarbon flow measurements has been constructed at National Metrology Institute of Japan (NMIJ). The facility was designed for the calibration of hydrocarbon flowmeters in the flow rate range between 3 and 300 m3/h. The expanded uncertainty is estimated to be 0.03 % for volumetric flow rate and 0.02 % for mass flow rate (coverage factor: k = 2). The primary standard is based on a static and gravimetric method with a flying start and finish. The facility consists of two test rigs using kerosene and light oil as working fluids. The test lines for the flowmeters are 50, 100 and 150 mm in diameter and three servo positive displacement meters are used as working standards. To verify the calibration performance, a Coriolis flowmeter, a turbine meter and a positive displacement flowmeter have been calibrated at both test rigs. Furthermore, an international comparison with SP, Swedish National Testing Research Institute, was carried out. A screw-type positive displacement flowmeter was selected as the transfer standard and was calibrated at NMIJ and SP. The result shows that the two national standards at the two institutes agree within the quoted expanded uncertainties.

ASHRAE Standard 62: tobacco industry's influence over national ventilation standards  

PubMed Central

Objective: To describe the role of the tobacco industry in the development of ventilation standards for indoor air quality by influencing the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE). Methods: Review of tobacco industry documents available on the internet between January 2001 and March 2002. Search terms included "ASHRAE", "ventilation", "minutes", "memo", and the names of key players and organisations as identified in the initial searches. Analysis of ASHRAE and other relevant documents publicly available and the personal files of a Standard 62 committee member; interviews of a selected number of ASHRAE players; observation of an ASHRAE meeting. Results: The tobacco industry has been involved in the development of ventilation standards for over 20 years. It has successfully influenced the standard and continues to attempt to change the standard from a smoke-free framework into an "accommodation" framework. The industry acts directly and through consultants and allies. The major health groups have been largely absent and the health interests have been poorly represented in standard development. While concentrated in the USA, ASHRAE standards are adopted worldwide. Conclusion: The tobacco industry determined that allowing smoking in ventilation standards for indoor air quality was a high priority and dedicated significant human and financial resources to ensure that its interests were represented. The health groups, until recently, have largely ignored the policy implications for tobacco control of standard development. This situation is changing, but unless health groups maintain high visibility within ASHRAE, the tobacco industry may succeed in creating a standard that ignores the dangers of secondhand smoke.

American National Standards: The Consensus Process  

NASA Technical Reports Server (NTRS)

Since the early 20th Century, technical and professional societies have developed standards within their areas of expertise addressing aspects of their industries which they feel would benefit from a degree of standardization. From the beginning, the use of these standards was strictly voluntary. It did not take jurisdictional authorities long, however, to recognize that application of these voluntary standards enhanced public safety, as well as leveling the playing field in trade. Hence, laws were passed mandating their use. Purchasers of goods and services also recognized the advantages of standardization, and began requiring the use of standards in their procurement contracts. But how do jurisdictions and purchasers know that the standard they are mandating is a broad-based industry standard, or a narrowly focused set of rules which only apply to one company or institution, thereby giving them an unfair advantage? The answer is "consensus", and a unified approach in achieving it.

Standards for Evaluating Radiosonde Measurements  

NASA Technical Reports Server (NTRS)

Radiosonde measurement errors occur for various reasons: calibration, mishandling of sensors, poor software, radiation, etc. It is important that these errors be found and corrected, or at the least, corrections determined that might be sensibly applied. Radiation errors apparently are the most serious since the lack of radiative equilibrium between the thermistor and its surrounding environment can not be corrected for just a single thermistor without serious intervention. However, errors may be determined using the Accurate Temperature Measuring (ATM) radiosonde. The ATM radiosonde development was initiated in the mid-1980's using three thermistors; five thermistors are presently incorporated in the ATM radiosonde. Test flights at different locations indicated that the radiative effect on the thermistor varies because of the different environment of each location and, can be corrected. When comparisons between different thermistors (radiosondes) are required the ATM is a valuable tool. Investigation of relative humidity measurements is an ongoing issue because of large discrepancies in observed data. The first chilled mirror (SNOW WHITE) radiosonde was flown from Wallops Flight Facility in 1997. Tests and analyses show the chilled mirror radiosonde present very acceptable data up to the altitude of the tropopause and in some measurements, to 100 hPA. Improvement and better interpretation of the measurements are important. Discussion concentrates on new aspects of the ATM radiosonde application and the utility of the chilled mirror radiosonde.

UK Food Standards Agency Workshop Consensus Report: the choice of method for measuring 25-hydroxyvitamin D to estimate vitamin D status for the UK National Diet and Nutrition Survey.  

PubMed

The consensus workshop, organised on behalf of the Food Standards Agency, was convened to recommend the most appropriate and secure method for measuring vitamin D status in the UK. Workshop participants (the Expert Panel) were invited on the basis of expertise in current 25-hydroxyvitamin D (25OHD) assays, or expertise in vitamin D nutrition and metabolism or detailed knowledge and experience in the National Diet and Nutrition Survey (NDNS). A decision support matrix, which set out the particular criteria by which the different options were scored and evaluated, was used to structure the discussion. The Expert Panel agreed that five methods for measuring 25OHD should be evaluated according to eleven criteria, selected on the basis of their relevance to the NDNS. All three of the evaluating subgroups of the Expert Panel produced similar total scores over the eleven criteria for the different methods; they scored LC-MS/MS and HPLC-UV similarly highly, while the scores for the immunoassay methods were lower. The Expert Panel recommended that an LC-MS/MS method should be the preferred method for the NDNS. A detailed specification for the method will be required to ensure comparability between NDNS and the National Health and Nutrition Examination Survey in the US facilitating future comparisons. The Expert Panel also recommended that the method should be carried out in a laboratory with appropriate expertise, competency and history of records of good performance. The method should be standardised against the National Institute of Standards and Technology SRM 972. If the recommended LC-MS/MS is adopted, the Expert Panel indicated that the method should be able to discriminate the C-3 epimer of 25OHD(3), especially if used to measure 25OHD in young infants in the forthcoming Diet and Nutrition Survey of Infants and Young Children, who are known to have high circulating concentrations of the C-3 epimer.

National Emission Standards for Hazardous Air Pollutants submittal -- 1997  

SciTech Connect

Each potential source of Nevada Test Site (NTS) emissions was characterized by one of the following methods: (1) monitoring methods and procedures previously developed at the NTS; (2) a yearly radionuclide inventory of the source, assuming that volatile radionuclide are released to the environment; (3) the measurement of tritiated water (as HTO or T{sub 2}O) concentration in liquid effluents discharged to containment ponds and assuming all the effluent evaporates over the course of the year to become an air emission; or (4) using a combination of environmental measurements and CAP88-PC to calculate emissions. The emissions for National Emission Standards for Hazardous Air Pollutants (NESHAPs) reporting are listed. They are very conservative and are used in Section 3 to calculate the EDE to the maximally exposed individual offsite. Offsite environmental surveillance data, where available, are used to confirm that calculated emissions are, indeed, conservative.

The /sup 235/U(n,f) reaction is the standard by which most neutron induced fission cross sections are determined. Most of these cross sections are derived from relatively easy ratio measurements to /sup 235/U. However, the more difficult /sup 235/U(n,f) cross section measurements require the use of advanced neutron detectors for the determination of the incident neutron fluence. Examples of recent standard cross section measurements are discussed, various neutron detectors are described, and the status of the /sup 235/U(n,f) cross section standard is assessed. 23 refs., 8 figs., 4 tabs.

IEC measurement standards for ultrasonic hydrophones and radiation force balances  

NASA Astrophysics Data System (ADS)

Acoustic output measurements of medical ultrasonic equipment are usually performed in water and using two widely established methods: ultrasonic power measurement with a radiation force balance and acoustic pressure measurement with an ultrasonic hydrophone. The International Electrotechnical Commission (IEC) has published a number of International Standards on both methods, prepared by its Technical Committee 87 ''Ultrasonics.'' These are discussed and future standardization trends are presented. The basic standard for ultrasonic power measurements is IEC 61161. It recommends using a radiation force balance and specifies the relevant technical properties and sources of uncertainty. It is currently envisaged to revise this standard and to include particular recommendations for the power range up to 20 W which have recently been worked out in an international cooperation of national metrology institutes. Hydrophone standards have continuously been developed over many years. The most recent one is IEC 62092 which extends the upper frequency limit of hydrophone standarization from 15 MHz to 40 MHz. The current trend is to reorganize all existing hydrophone standards and to find a new scheme of three parallel standards dealing with hydrophone properties, hydrophone use, and hydrophone calibration.

Standard deviation of scatterometer measurements from space.  

NASA Technical Reports Server (NTRS)

The standard deviation of scatterometer measurements has been derived under assumptions applicable to spaceborne scatterometers. Numerical results are presented which show that, with sufficiently long integration times, input signal-to-noise ratios below unity do not cause excessive degradation of measurement accuracy. The effects on measurement accuracy due to varying integration times and changing the ratio of signal bandwidth to IF filter-noise bandwidth are also plotted. The results of the analysis may resolve a controversy by showing that in fact statistically useful scatterometer measurements can be made from space using a 20-W transmitter, such as will be used on the S-193 experiment for Skylab-A.

EP&R Standards Project Report: Technical Review of National Incident Management Standards  

SciTech Connect

The importance and necessity for a fully developed and implemented National Incident Management System (NIMS) has been demonstrated in recent years by the impact of national events such as Hurricane Katrina in 2005. Throughout the history of emergency response to major disasters, especially when multiple response organizations are involved, there have been systemic problems in the consistency and uniformity of response operations. Identifying national standards that support the development and implementation of NIMS is key to helping solve these systemic problems. The NIMS seeks to provide uniformity and consistency for incident management by using common terminology and protocols that will enable responders to coordinate their efforts to ensure an efficient response.

Measuring Pressure Has a New Standard  

NASA Technical Reports Server (NTRS)

The Force-Balanced Piston Gauge (FPG) tests and calibrates instrumentation operating in the low pressure range. The system provides a traceable, primary calibration standard for measuring pressures in the range of near 0 to 15 kPa (2.2 psi) in both gauge and absolute measurement modes. The hardware combines a large area piston-cylinder with a load cell measuring the force resulting from pressures across the piston. The mass of the piston can be tared out, allowing measurement to start from zero. A pressure higher than the measured pressure, which keeps the piston centered, lubricates an innovative conical gap located between the piston and the cylinder, eliminating the need for piston rotation. A pressure controller based on the control of low gas flow automates the pressure control. DHI markets the FPG as an automated primary standard for very low-gauge and absolute pressures. DHI is selling the FPG to high-end metrology laboratories on a case by case basis, with a full commercial release to follow.

Standardization and conversion of marker polymorphism measures.  

PubMed

Large scale gene mapping efforts in domestic animals have generated and mapped a large number of genetic markers that are useful for mapping quantitative trait and disease loci and for DNA diagnostic purposes such as parentage testing. Marker polymorphism is an important criterion for selecting genetic markers in planning experiment for mapping quantitative trait loci or for DNA diagnostic purposes. Current formulations of marker polymorphism measures are functions of marker allele frequencies. In this study, two measures of marker polymorphism that are available from gene mapping studies and do not require allele frequencies were proposed and analyzed: the observed polymorphic information content (PIC) and the observed family information content (FIC). The observed FIC was more stable than the observed PIC because the observed FIC is unaffected by the variation in the frequency of heterozygous parents. However, both FIC and PIC are dependent on the gene mapping design. The effective number of alleles is recommended as a tool to standardize marker polymorphism measures so that polymorphism of different markers can be compared on an equal basis, and to obtain a new polymorphism measure (such an exclusion probability) from an existing measure (such as FIC). The usage of the effective number of alleles to standardize FIC, PIC and exclusion probabilities is illustrated using genetic markers in a published linkage map. PMID:10654428

1998 INEEL National Emission Standard for Hazardous Air Pollutants - Radionuclides  

SciTech Connect

Under Section 61.94 of Title 40, Code of Federal Regulations (CFR), Part 61, Subpart H, ''National Emission Standards for Emission of Radionuclides Other Than Radon From Department of Energy Facilities,'' each Department of Energy (DOE) facility must submit an annual report documenting compliance. This report addresses the Section 61.94 reporting requirements for operations at the Idaho National Engineering and Environmental Laboratory (INEEL) for calendar year (CY) 1998. The Idaho Operations Office of the DOE is the primary contract concerning compliance with the National Emission Standards for Hazardous Air Pollutants (NESHAPs) at the INEEL. For CY 1998, airborne radionuclide emissions from the INEEL operations were calculated to result in a maximum individual dose to a member of the public of 7.92E-03 mrem (7.92E-08 Sievert). This effective dose equivalent (EDE) is well below the 40 CFR 61, Subpart H, regulatory standard of 10 mrem per year (1.0E-04 Sievert per year).

National Emission Standards for Hazardous Air Pollutants Calendar Year 2005  

SciTech Connect

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office (NNSA/NSO). From 1951 through 1992, the NTS was operated as the nation’s site for nuclear weapons testing. The release of man-made radionuclides from the NTS as a result of testing activities has been monitored since the first decade of atmospheric testing. After 1962, when nuclear tests were conducted only underground, the radiation exposure to the public surrounding the NTS was greatly reduced. After the 1992 moratorium on nuclear testing, radiation monitoring on the NTS focused on detecting airborne radionuclides that are resuspended into the air (e.g., by winds, dust-devils) along with historically-contaminated soils on the NTS. To protect the public from harmful levels of man-made radiation, the Clean Air Act, National Emission Standards for Hazardous Air Pollutants (NESHAP) (40 Code of Federal Regulations 61 Subpart H) limits the release of radioactivity from a U. S. Department of Energy (DOE) facility (e.g., the NTS) to 10 millirem per year (mrem/yr) effective dose equivalent (EDE) to any member of the public. This is the dose limit established for someone living off of the NTS for inhaling radioactive particles that may be carried by wind off of the NTS. This limit assumes that members of the public surrounding the NTS may also inhale “background levels” or radioactive particles unrelated to NTS activities that come from naturally-occurring elements in the environment (e.g., radon gas from the earth or natural building materials) or from other man-made sources (e.g., cigarette smoke). The U. S. Environmental Protection Agency (EPA) requires DOE facilities (e.g., the NTS) to demonstrate compliance with the NESHAP dose limit by annually estimating the dose to a hypothetical member of the public, referred to as the maximally exposed individual (MEI), or the member of the public who resides within an 80-kilometer (50-mile) radius of the facility who would experience the highest annual dose. This dose to a hypothetical person living close to the NTS cannot exceed 10 mrem/yr. C.1 This report has been produced annually for the EPA Region IX, and for the state of Nevada since 1992 and documents that the estimated EDE to the MEI has been, and continues to be, well below the NESHAP dose limit. The report format and level of technical detail has been dictated by the EPA and DOE Headquarters over the years. It is read and evaluated for NESHAP compliance by federal and state regulators. Each section and appendix presents technical information (e.g., NTS emission source estimates, onsite air sampling data, air transport model input parameters, dose calculation methodology, etc.), which supports the annual dose assessment conclusions. In 2005, as in all previous years for which this report has been produced, the estimated dose to the public from inhalation of radiological emissions from current and past NTS activities is shown to be well below the 10 mrem/yr dose limit. This was demonstrated by air sampling data collected onsite at each of six EPA-approved “critical receptor” stations on the NTS. The sum of measured EDEs from the four stations at the NTS boundaries is 2.5 mrem/yr. This dose is 25 percent of the allowed NESHAP dose limit. Because the nearest member of the public resides approximately 20 kilometers (12 miles) from the NTS boundary, this individual receives only a small fraction of this dose. NESHAP compliance does not require DOE facilities to estimate annual inhalation dose from non-DOE activities. Therefore, this report does not estimate public radiation doses from any other sources or activities (e.g., naturally-occurring radon, global fallout).

Standardized Testing of Phasor Measurement Units  

SciTech Connect

This paper describes a set of tests used to determine Phasor Measurement Unit (PMU) measurement characteristics under steady state and dynamic conditions. The methodology is repeatable, comparable among test facilities, and can be performed at any facility with commonly available relay and standard test equipment. The methodology is based upon using test signals that are mathematically generated from a signal model and played into the PMU with precise GPS synchronization. Timing flags included with the test signal provide correlate the test signals and the PMU output. This allows accurate comparison of the phasor model with the value estimated by the PMU for accurate performance analysis. The timing flags also facilitate programmed plot and report generation.

Recommendations for a commercial vehicle to roadway communications national standard  

SciTech Connect

This is the final report by the Lawrence Livermore National Laboratory (LLNL). Based on the authors studies of the Electronic Toll and Traffic Management (ETTM) industry, they make recommendations for a possible future national standard for short range Vehicle-to-Roadway Communications (VRC) for Commercial Vehicle Operations (CVO). Of primary interest to the Federal Highway Administration are Mainline Automated Clearance Systems (MACS). In such a system, CVs would exchange data with weigh-stations and ports of entry at highway speeds using wireless Radio Frequency (RF) techniques and to enable automated clearance. The CV would carry a transponder (or tag) and transmit electronic credentials, safety data, in-transit data, etc. on command from a roadside transceiver (or reader) upstream from the weigh-station or port of entry. Computer processing of this data, plus the weigh-in-motion reading and historical information, would be used to decide whether to direct the truck to stop for manual clearance or proceed.

Pediatric fasting times before surgical and radiologic procedures: benchmarking institutional practices against national standards.  

PubMed

Prolonged preoperative fasting can be associated with adverse outcomes, particularly in children. Our aims were to assess the time pediatric patients fasted prior to surgical or radiologic procedures and evaluate whether fasting (NPO) orders complied with national guidelines. We measured NPO start time, time of last intake, and time test or surgery was scheduled, took place, or was cancelled in 219 pediatric patients. Findings demonstrate that pediatric patients experienced prolonged fasting before procedures and that the majority of NPO orders were non-compliant with national guidelines. We have developed strategies to reduce fasting times and ensure compliance with recommended national fasting standards. PMID:24365219

National academy of sciences "standardization": on what terms?  

PubMed

The frequently cited 2009 National Academy of Sciences Report entitled "Strengthening Forensic Science in the United States: A Path Forward" has become a focal point of forensic science practitioners' discussions and research since its publication. One of its recommendations is "Standardized Terminology and Reporting". Little has been published to date on this topic, although conversations and dialogs on the subject are ongoing. The upshot of this communication is to draw attention to the problem of one term in particular, perimortem, which may be only the proverbial "tip of the iceberg" in the lexicon-related concerns of forensic scientists. Even if it is an isolated issue, it is one that reflects the need for a consensus on term use and definitions by interdisciplinary practitioners who are currently using the term haphazardly, to the confusion of colleagues and potentially finders-of-fact in the courts.

This rule proposes a standard for a national health care provider identifier and requirements concerning its use by health plans, health care clearinghouses, and health care providers. The health plans, health care clearinghouses, and health care providers would use the identifier, among other uses, in connection with certain electronic transactions. The use of this identifier would improve the Medicare and Medicaid programs, and other Federal health programs and private health programs, and the effectiveness and efficiency of the health care industry in general, by simplifying the administration of the system and enabling the efficient electronic transmission of certain health information. It would implement some of the requirements of the Administrative Simplification subtitle of the Health Insurance Portability and Accountability Act of 1996. PMID:10179329

SciTech Connect

Two alpha-particle counting systems for the measurement of large-area sources were developed at the National Bureau of Standards. The systems and their characteristics are described. One system uses an internal-source proportional counter and the other measures sources external to the counting volume through a thin aluminized mylar window. The internal system is used to measure sources in the lower-activity ranges. These calibrated sources are then used to establish the efficiency of the external counter used to measure the higher-activity sources.

The USDA Agricultural Research Service Nutrient Data Laboratory presents the National Nutrient Database, which has an easy-to-search interface that quickly retrieves nutritional data for every food item that contains a specific keyword. For instance, searching for "soybean" calls up a long list of food items for which soybean is an ingredient: various margarines, salad dressings, and oils; raw soybeans; steamed soybeans; roasted soybeans; and so on. The complete nutrition report for each item can then be viewed after selecting a unit of measurement (e.g., per 100 grams). The database may also be search by single nutrients, such as iron or folic acid.

Urban-aerosol acids: Analysis of National Institute of Standards and Technology Standard Reference Material 1649  

SciTech Connect

Urban air particulate matter, collected from Washington, D.C. and certified by the National Institute of Standards and Technology (NIST) as Standard Reference Material 1649, was extracted and fractionated into acid, base and neutral fractions. Each fraction was tested for biological activity using a microbial mutagenesis assay system. The organic acid fraction showed unexpectedly high mutagenic activity, and was subjected to chemical characterization studies. Following derivatization, analysis by GC/MS showed the presence of fatty acids, aromatic acids (including phenolic compounds), and a significant number of compounds that could not be identified from mass spectral compendia. Spectroscopic and elemental analysis data supported the characterization of the fraction as predominantly aromatic. Mass spectra from both GC/MS and direct probe analysis showed the presence of a chlorinated substance, subsequently identified as the fungicide Dichlorophen. The compound was shown to comprise over 50 percent of the mass of the organic acid fraction. A reference standard of Dichlorophen was not mutagenic. The presence of the fungicide in the NIST certified urban aerosol is, in all probability due to artifactual processes. Attempts to concentrate the observed mutagenic activity by preparative chromatography and acid/base partition experiments were not successful.

Biases in Multicenter Longitudinal PET Standardized Uptake Value Measurements1  

PubMed Central

This study investigates measurement biases in longitudinal positron-emission tomography/computed tomography (PET/CT) studies that are due to instrumentation variability including human error. Improved estimation of variability between patient scans is of particular importance for assessing response to therapy and multicenter trials. We used National Institute of Standards and Technology-traceable calibration methodology for solid germanium-68/gallium-68 (68Ge/68Ga) sources used as surrogates for fluorine-18 (18F) in radionuclide activity calibrators. One cross-calibration kit was constructed for both dose calibrators and PET scanners using the same 9-month half-life batch of 68Ge/68Ga in epoxy. Repeat measurements occurred in a local network of PET imaging sites to assess standardized uptake value (SUV) errors over time for six dose calibrators from two major manufacturers and for six PET/CT scanners from three major manufacturers. Bias in activity measures by dose calibrators ranged from -50% to 9% and was relatively stable over time except at one site that modified settings between measurements. Bias in activity concentration measures by PET scanners ranged from -27% to 13% with a median of 174 days between the six repeat scans (range, 29 to 226 days). Corresponding errors in SUV measurements ranged from -20% to 47%. SUV biases were not stable over time with longitudinal differences for individual scanners ranging from -11% to 59%. Bias in SUV measurements varied over time and between scanner sites. These results suggest that attention should be paid to PET scanner calibration for longitudinal studies and use of dose calibrator and scanner cross-calibration kits could be helpful for quality assurance and control.

Grid-enabled measures: using Science 2.0 to standardize measures and share data.  

PubMed

Scientists are taking advantage of the Internet and collaborative web technology to accelerate discovery in a massively connected, participative environment--a phenomenon referred to by some as Science 2.0. As a new way of doing science, this phenomenon has the potential to push science forward in a more efficient manner than was previously possible. The Grid-Enabled Measures (GEM) database has been conceptualized as an instantiation of Science 2.0 principles by the National Cancer Institute (NCI) with two overarching goals: (1) promote the use of standardized measures, which are tied to theoretically based constructs; and (2) facilitate the ability to share harmonized data resulting from the use of standardized measures. The first is accomplished by creating an online venue where a virtual community of researchers can collaborate together and come to consensus on measures by rating, commenting on, and viewing meta-data about the measures and associated constructs. The second is accomplished by connecting the constructs and measures to an ontological framework with data standards and common data elements such as the NCI Enterprise Vocabulary System (EVS) and the cancer Data Standards Repository (caDSR). This paper will describe the web 2.0 principles on which the GEM database is based, describe its functionality, and discuss some of the important issues involved with creating the GEM database such as the role of mutually agreed-on ontologies (i.e., knowledge categories and the relationships among these categories--for data sharing).

Development of a Primary Standard for Calibration of [18F]FDG Activity Measurement Systems  

NASA Astrophysics Data System (ADS)

The 18F national primary standard was developed by the INMRI-ENEA using the 4?? Liquid Scintillation Spectrometry Method with 3H-Standard Efficiency Tracing. Measurements were performed at JRCIspra under a scientific collaboration between the Institute for Health and Consumer Production, the Amersham Health and the National Institute for Occupational Safety and Prevention (ISPESL). The goal of the work was to calibrate, with minimum uncertainty, the INMRI-ENEA transfer standard portable well-type ionisation chamber as well as other JRC-Ispra and Amersham Health reference Ionising Chambers used for FDG activity measurement.

Improving registration measurement capability by defining a 2D grid standard using multiple registration measurement tools  

NASA Astrophysics Data System (ADS)

Currently all LMS IPRO pattern placement metrology tools are calibrated using a 1D length standard provided by a national standards institute (e.g. NIST or PTB), however there are no 2-D standards available with an uncertainty matching the requirements of mask manufacturing for the 22nm HP node and beyond. Therefore, the 2D stage coordinate system of the LMS IPRO systems is calibrated using KLA Tencor's proprietary combined correction technique. With introduction of the LMS IPRO4 into high volume mask production at the AMTC, AMTC and KLA-Tencor MIE have demonstrated the capability to match IPRO3 and IPRO4 grids within 1.2 nm uncertainty [1]. Using the Golden Tool approach, we achieved a significant improvement in pattern placement measurement capability of previous generation measurement tools of up to 30%. This in turn leads to improved pattern placement metrology fleet capability and extended useful lifetime of capital equipment. The use of multiple high end registration measurement tools enables the creation of a 2D coordinate system standard, which could be used for improved fleet matching and would help improve the capability of older generation pattern placement metrology tools by matching to this standard. Within this paper Golden Tool and Round Robin worldwide fleet matching approaches are compared and discussed.

OBJECTIVE This study compared program measures of assertive community treatment (ACT) with standards of accreditation for the patient-centered medical home (PCMH) to determine whether there were similarities in the infrastructure of the two methods of service delivery and whether high-fidelity ACT teams would qualify for medical home accreditation. METHODS The authors compared National Committee for Quality Assurance PCMH standards with two ACT fidelity measures (the Dartmouth Assertive Community Treatment Scale and the Tool for Measurement of Assertive Community Treatment [TMACT]) and with national ACT program standards. RESULTS PCMH standards pertaining to enhanced access and continuity, management of care, and self-care support demonstrated strong overlap across ACT measures. Standards for identification and management of populations, care coordination and follow-up, and quality improvement demonstrated less overlap. The TMACT and the program standards had sufficient overlap to score in the range of a level 1 PCMH, but no ACT measure sufficiently detailed methods of population-based screening and tracking of referrals to satisfy "must-pass" elements of the standards. CONCLUSIONS ACT measures and medical home standards had significant overlap in innate infrastructure. ACT teams following the program standards or undergoing TMACT fidelity review could have the necessary infrastructure to serve as medical homes if they were properly equipped to supervise general medical care and administer activities to improve management of chronic diseases.

The emergence of MS-based proteomic platforms as a prominent technology utilized in biochemical and biomedical research has increased the need for high-quality MS measurements. To address this need, National Institute of Standards and Technology (NIST) reference material (RM) 8323 yeast protein extract is introduced as a proteomics quality control material for benchmarking the preanalytical and analytical performance of proteomics-based experimental workflows. RM 8323 yeast protein extract is based upon the well-characterized eukaryote Saccharomyces cerevisiae and can be utilized in the design and optimization of proteomics-based methodologies from sample preparation to data analysis. To demonstrate its utility as a proteomics quality control material, we coupled LC-MS/MS measurements of RM 8323 with the NIST MS Quality Control (MSQC) performance metrics to quantitatively assess the LC-MS/MS instrumentation parameters that influence measurement accuracy, repeatability, and reproducibility. Due to the complexity of the yeast proteome, we also demonstrate how NIST RM 8323, along with the NIST MSQC performance metrics, can be used in the evaluation and optimization of proteomics-based sample preparation methods.

Standard reference surfaces for work function measurements in air  

NASA Astrophysics Data System (ADS)

Determining work functions (WFs) using a Kelvin probe requires a known standard. In air there was no reliable standard until use of electrochemical half-cells was proposed and developed. Here the use of highly oriented graphite, HOPG, is shown to work well as an additional standard, useable in air or vacuum. The values of the WFs of these standards are given, and the precision and accuracy of measurements using them are discussed. Actual examples and some detailed procedures are included.

Measurements and data of thermophysical properties traceable to a metrological standard  

NASA Astrophysics Data System (ADS)

In order to improve the performance of devices, components and systems, where heat is generated, transported, stored or converted to other types of energy, reliable thermal design and simulation are required using reliable thermophysical property data. In order to produce reliable thermophysical property data systematically and continually, the international and national standards of thermophysical properties must be established and the measurement methods should be evaluated and standardized, and the measuring instruments must be calibrated by reference materials traceable to the international or national standard. Users search for and purchase a particular grade of material which satisfies the properties, performances and technical specifications required. In order to guarantee fair commerce and trade, values of thermophysical properties should be measured traceable to the national standard. Thus, the establishment of an international standard is required satisfying the global CIPM MRA under the metric convention, and then, the global and regional framework to examine calibration and measurement capability of national metrology institutes (NMIs). A domestic traceability system in each country should be established and the quality management system of the NMI and calibration laboratories should be constructed based on ISO 17025.

Microgravity effects on standardized cognitive performance measures  

NASA Technical Reports Server (NTRS)

The purpose of this experiment, selected to fly on the International Microgravity Laboratory (IML-2) Spacelab mission, is to determine the effects of microgravity upon the cognitive skills which are critical to successful performance of many tasks on board the Space Shuttle. Six tests from the Unified Tri-service Cognitive Performance Assessment Battery (UTC-PAB) will be administered to the Mission Specialists to fulfill the goals of this experiment. These tests are based upon current theoretical models of human performance and the hypothesized effects of microgravity. The principle objective is the identification of the effects of microgravity upon specific information processing skills affecting performance from those of fatigue and shifts in work/rest cycles. Multiple measures of both short and long term fatigue will be obtained and used as a major independent variable for the analysis of these performance data. Scientific supporting studies will determine optimum practice and performance testing schedules for the astronauts. The same tests will be used post-flight to collect data on the recovery of any cognitive performance impairment compared with pre-flight, baseline levels.

A Network for Standardized Ocean Color Validation Measurements  

NASA Technical Reports Server (NTRS)

The Aerosol Robotic Network (AERONET) was developed to support atmospheric studies at various scales with measurements from worldwide distributed autonomous sunphotometers [Holben et al. 1998]. AERONET has now extended its support to marine applications through the additional capability of measuring the radiance emerging from the sea with modified sun-photometers installed on offshore platforms like lighthouses, navigation aids, oceanographic and oil towers. The functionality of this added network component called AERONET - Ocean Color (AERONET-OC), has been verified at different sites and deployment structures over a four year testing phase. Continuous or occasional deployment platforms (see Fig. 1) included: the Acqua Alta Oceanographic Tower (AAOT) of the Italian National Research Council in the northern Adriatic Sea since spring 2002; the Martha s Vineyard Coastal Observatory (MVCO) tower of the Woods Hole Oceanographic Institution in the Atlantic off the Massachusetts coast for different periods since spring 2004; the TOTAL Abu-Al-Bukhoosh oil Platform (AABP, shown through an artistic rendition in Fig. 1) in the Persian (Arabian) Gulf in fall 2004; the Gustaf Dal n Lighthouse Tower (GDLT) of the Swedish Maritime Administration in the Baltic Sea in summer 2005; and the platform at the Clouds and the Earth's Radiant Energy System (CERES) Ocean Validation Experiment (COVE) site located in the Atlantic Ocean off the Virginia coast since fall 2005. Data collected during the network testing phase, confirm the capability of AERONET-OC to support the validation of marine optical remote sensing products through standardized measurements of normalized water-leaving radiance, LWN, and aerosol optical thickness, a, at multiple coastal sites.

The toolbox of fluorescence standards: flexible calibration tools for the standardization of fluorescence-based measurements  

NASA Astrophysics Data System (ADS)

To improve the reliability of fluorescence data in the life and material sciences and to enable accreditation of fluorescence techniques, standardization concepts are required that guarantee and improve the comparability of fluorescence measurements. At the core of such concepts are simple and evaluated fluorescence standards for the consideration of instrument-specific spectral and intensity distortions of measured signals and for instrument performance validation (IPV). Similarly in need are fluorescence intensity standards for the quantification from measured intensities and for signal referencing, thereby accounting for excitation light-induced intensity fluctuations. These standards should be preferably certified, especially for use in regulated areas like medical diagnostics. This encouraged us to develop liquid and solid standards for different fluorescence parameters and techniques for use under routine measurement conditions in different formates. Special emphasis was dedicated to the determination and control of the spectral responsivity of detection systems, wavelength accuracy, homogeneity of illumination, and intensity referencing for e.g. spectrofluorometers, fluorescence sensors and confocal laser scanning fluorescence microscopes. Here, we will present design concepts and examples for mono- and multifunctional fluorescence standards that provide traceability to radiometric units and present a first step towards a toolbox of standards.

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office (NNSA/NSO). From 1951 through 1992, the NTS was operated as the nation's site for nuclear weapons testing. The release of man-made radionuclides from the NTS as a result of testing activities has been monitored since the first decade of atmospheric testing. After 1962, when nuclear tests were conducted only underground, the radiation exposure to the public surrounding the NTS was greatly reduced. After the 1992 moratorium on nuclear testing, radiation monitoring on the NTS focused on detecting airborne radionuclides which come from historically-contaminated soils resuspended into the air (e.g., by winds) and tritium-contaminated soil moisture emitted to the air from soils through evapotranspiration.

Development and status of data quality assurance program at NASA Langley research center: Toward national standards  

NASA Technical Reports Server (NTRS)

As part of a continuing effort to re-engineer the wind tunnel testing process, a comprehensive data quality assurance program is being established at NASA Langley Research Center (LaRC). The ultimate goal of the program is routing provision of tunnel-to-tunnel reproducibility with total uncertainty levels acceptable for test and evaluation of civilian transports. The operational elements for reaching such levels of reproducibility are: (1) statistical control, which provides long term measurement uncertainty predictability and a base for continuous improvement, (2) measurement uncertainty prediction, which provides test designs that can meet data quality expectations with the system's predictable variation, and (3) national standards, which provide a means for resolving tunnel-to-tunnel differences. The paper presents the LaRC design for the program and discusses the process of implementation.

Measurement uncertainties for vacuum standards at Korea Research Institute of Standards and Science  

SciTech Connect

The Korea Research Institute of Standards and Science has three major vacuum systems: an ultrasonic interferometer manometer (UIM) (Sec. II, Figs. 1 and 2) for low vacuum, a static expansion system (SES) (Sec. III, Figs. 3 and 4) for medium vacuum, and an orifice-type dynamic expansion system (DES) (Sec. IV, Figs. 5 and 6) for high and ultrahigh vacuum. For each system explicit measurement model equations with multiple variables are, respectively, given. According to ISO standards, all these system variable errors were used to calculate the expanded uncertainty (U). For each system the expanded uncertainties (k=1, confidence level=95%) and relative expanded uncertainty (expanded uncertainty/generated pressure) are summarized in Table IV and are estimated to be as follows. For UIM, at 2.5-300 Pa generated pressure, the expanded uncertainty is <4.17x10{sup -2} Pa and the relative expanded uncertainty is <1.18x10{sup -2}; at 1-100 kPa generated pressure, the expanded uncertainty is <7.87 Pa and the relative expanded uncertainty is <7.84x10{sup -5}. For SES, at 3-100 Pa generated pressure, the expanded uncertainty is <1.77x10{sup -1} Pa and the relative expanded uncertainty is <1.81x10{sup -3}. For DES, at 4.6x10{sup -3}-1.3x10{sup -2} Pa generated pressure, the expanded uncertainty is <1.04x10{sup -4} Pa and the relative expanded uncertainty is <8.37x10{sup -3}; at 3.0x10{sup -6}-9.0x10{sup -4} Pa generated pressure, the expanded uncertainty is <8.21x10{sup -6} Pa and the relative expanded uncertainty is <1.37x10{sup -2}. Within uncertainty limits our bilateral and key comparisons [CCM.P-K4 (10 Pa-1 kPa)] are extensive and in good agreement with those of other nations (Fig. 8 and Table V)

The Nevada Test Site (NTS) is operated by the US Department of Energy's Nevada Operations Office (DOE/NV) as the site for nuclear weapons testing, now limited to readiness activities and experiments in support of the national Stockpile Stewardship Management Program. It is located in Nye County, Nevada, with the southeast corner about 105 km (65 mi) northwest of Las Vegas, Nevada. The NTS covers about 3,561 km{sup 2} (1,375 mi{sup 2}), an area larger than Rhode Island. Its size is about 46 to 56 km (28 to 35 mi) east to west and from 64 to 88 km (40 to 55 mi) north to south. The NTS is surrounded, except on the south side, by public exclusion areas (Nellis Air Force Range [NAFR]) that provide another 24 to 104 km (15 to 65 mi) between the NTS and public lands. The NTS is characterized by desert valley and Great Basin mountain topography, with a climate, flora, and fauna typical of the southwest deserts. Population density within 150 km (93 mi) of the NTS is only about 0.2 persons per square kilometer, excluding the Las Vegas area. Restricted access, low population density in the surrounding area, and extended wind transport times are advantageous factors for the activities conducted at the NTS. Surface waters are scarce on the NTS and there is great depth to slow-moving groundwater.

The Milk Powder Standard Reference Material, SRM 1549, recently prepared by the National Bureau of Standards has been analyzed by instrumental and radiochemical neutron activation analysis. The extremely low levels of many of the elements of interest, combined with the high levels of many of the matrix elements, necessitated improvements in many of the existing analytical procedures. Special attention has been given to reducing and evaluating the analytical uncertainties. Bovine Liver, SRM 1577, was analyzed as a control and the results obtained were compared with the literature and the NBS certified values.

NIST New Humidity Standard for Water Vapor Measurements in Troposphere and Stratosphere  

NASA Astrophysics Data System (ADS)

The National Institute of Standards and Technology (NIST) realizes, maintains, and disseminates the national measurement standards for humidity and that for many years it has provided industry, government and academia a service for the calibration of water vapor-measuring instruments. NIST has developed a precision humidity standard, based on the principle of divided flow, for producing air of known mixing ratios in the range 0.5 ppm to 1050 ppm by volume with a maximum expanded uncertainty (coverage factor k=2, corresponding to approximately 95% confidence level) of 0.26 % of the value. This high accuracy is accomplished by combining precise flow element standards with high purity mass flow controllers. Specific mixing ratios at the desired volumetric flow rate are determined by activating the appropriate valves via a computer-controlled multiplexer. The wet gas stream is produced by operating a standard saturator maintained at a constant temperature 1 °C and pressure 0.3 MPa in order to achieve a combined uncertainty of 0.1 % of 2214 ppm by volume in water vapor concentration. The new NIST standard can be used to calibrate various hygrometers currently used for atmospheric water vapor measurements in the upper troposphere and lower stratosphere, such as atmospheric pressure ionization mass spectrometer (APIMS), chemical ionization mass spectrometer (CIMS), infrared optical hygrometer, chilled-mirror frost-point hygrometer, Lyman-alpha hygrometer and microwave refractometer. A laboratory calibration provides essentially the Type B standard uncertainty of the mean value measured by a hygrometer as mentioned above. Type A evaluation of standard uncertainty, which characterize the dispersion of the observed values about their mean, is then combined to determine the expanded uncertainty of a measurand. It is essential that field instruments receive basic calibration under carefully controlled laboratory conditions. NIST calibrations may help resolve the long-standing discrepancies observed in water vapor measurements from aircraft platforms.

Experience with local lymph node assay performance standards using standard radioactivity and nonradioactive cell count measurements.  

PubMed

The local lymph node assay (LLNA) is the preferred test for identification of skin-sensitizing substances by measuring radioactive thymidine incorporation into the lymph node. To facilitate acceptance of nonradioactive variants, validation authorities have published harmonized minimum performance standards (PS) that the alternative endpoint assay must meet. In the present work, these standards were applied to a variant of the LLNA based on lymph node cell counts (LNCC) run in parallel as a control with the standard LLNA with radioactivity measurements, with threshold concentrations (EC3) being determined for the sensitizers. Of the 22 PS chemicals tested in this study, 21 yielded the same results from standard radioactivity and cell count measurements; only 2-mercaptobenzothiazole was positive by LLNA but negative by LNCC. Of the 16 PS positives, 15 were positive by LLNA and 14 by LNCC; methylmethacrylate was not identified as sensitizer by either of the measurements. Two of the six PS negatives tested negative in our study by both LLNA and LNCC. Of the four PS negatives which were positive in our study, chlorobenzene and methyl salicylate were tested at higher concentrations than the published PS, whereas the corresponding concentrations resulted in consistent negative results. Methylmethacrylate and nickel chloride tested positive within the concentration range used for the published PS. The results indicate cell counts and radioactive measurements are in good accordance within the same LLNA using the 22 PS test substances. Comparisons with the published PS results may, however, require balanced analysis rather than a simple checklist approach. PMID:21618258

ISO standardization to ensure traceability of vibration and shock acceleration measurements  

NASA Astrophysics Data System (ADS)

Traceability to the International System of Units (SI) is increasingly demanded for vibration and shock measurements as specified in international standards, recommendations, and regulations to ensure product quality, health, and safety. Hierarchies of measurement standards have been established and are operated at the National Metrology Institutes (NMIs) as well as accredited and nonaccredited calibration laboratories. To meet the increasing demands, a revision of the ISO 5347 series, renumbered to ISO 16063, started in 1995 (ISO TC 108). Improved and new standard methods for vibration and shock calibration have been specified at the different traceability levels. For primary vibration calibration by laser interferometry at the NMI level, ISO 16063-11:1999 has extended the frequency range (0,4 Hz-10 kHz) and included absolute-phase shift measurement. ISO 16063-13:2001 provides interferometric primary shock calibration (100 m/s2-100000 m/s2). For vibration and shock calibration at lower levels, parts 21 and 22 of ISO 16063 provide upgraded comparison methods. ISO standards for the calibration of angular transducers by laser interferometry (part 15) and by comparison (part 23) are under development. Using the methods specified, national standards and calibration equipment have been developed for calibration laboratories, offering many new and improved calibration and measurement capabilities and thus international traceability.

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Operations Office (NNSA/NV) as the site for nuclear weapons testing, now limited to readiness activities, experiments in support of the national Stockpile Stewardship Program, and the activities listed below. Located in Nye County, Nevada, the site's southeast corner is about 88 km (55 mi) northwest of the major population center, Las Vegas, Nevada. The NTS covers about 3,561 km2 (1,375 mi2), an area larger than Rhode Island. Its size is 46 to 56 km (28 to 35 mi) east to west and from 64 to 88 km (40 to 55 mi) north to south. The NTS is surrounded, except on the south side, by public exclusion areas (Nellis Air Force Range [NAFR]) that provide another 24 to 104 km (15 to 65 mi) between the NTS and public lands (Figure 1.0). The NTS is characterized by desert valley and Great Basin mountain topography, with a climate, flora, and fauna typical of the southwest deserts. Population density within 150 km (93 mi) of the NTS is only about 0.2 persons per square kilometer, excluding the Las Vegas area. Restricted access, low population density in the surrounding area, and extended wind transport times are advantageous factors for the activities conducted at the NTS. Surface waters are scarce on the NTS, and slow-moving groundwater is present hundreds to thousands of feet below the land surface. The sources of radionuclides include current and previous activities conducted on the NTS (Figure 2.0). The NTS was the primary location for testing of nuclear explosives in the Continental U.S. between 1951 and 1992. Historical testing above or at ground surface has included (1) atmospheric testing in the 1950s and early 1960s, (2) earth-cratering experiments, and (3) open-air nuclear reactor and rocket engine testing. Since the mid-1950s, testing of nuclear explosive devices has occurred underground in drilled vertical holes or in mined tunnels (DOE 1996a). No such tests have been conducted since September 23, 1992 (DOE 2000). Limited non-nuclear testing includes spills of hazardous materials at the Hazardous Materials Spill Center, private technology development, aerospace and demilitarization activities, and site remediating activities. Processing of radioactive materials is limited to laboratory analyses, and handling is restricted to transport, storage, and assembly of nuclear explosive devices and operation of radioactive waste management sites (RWMSs) for low-level radioactive and mixed waste (DOE 1996a). Monitoring and evaluation of the various activities conducted onsite indicate that the potential sources of offsite radiation exposure in CY 2001 were releases from (1) evaporation of tritiated water (HTO) from containment ponds that receive drainage water from E Tunnel in Area 12 and from discharges of two wells (Well U-3cn PS No. 2 and Well ER-20-5 No.3) into lined ponds, (2) onsite radio analytical laboratories, (3) the Area 5 RWMS (RWMS-5) facility, and (4) diffuse sources of tritium and re- suspension of plutonium and americium. The following sections present a general description of the present sources on the NTS and at the North Las Vegas Facility.

Los Alamos National Laboratory standard nuclear material container  

SciTech Connect

The shut down of United States (U.S.) nuclear-weapons production activities in the early 1990s left large quantities of nuclear materials throughout the U.S. Department of Energy (DOE) complex in forms not intended for long-term storage. In May 1994, the Defense Nuclear Facilities Safety Board (DNFSB) issued Recommendation 94-1, which called for the stabilization and disposition of 'thousands of containers of plutonium-bearing liquids and solids' in the DOE complex, including LANL in the nuclear-weapons-manufacturing pipeline when manufacturing ended. This resulted in the development of the 3013 standard with container requirements for long term storage (up to 50 years). A follow on was the Criteria For Interim Storage of Plutonium Bearing Materials, Charles B. Curtis, in 1996 to address storage other than the 3013 standard for shorter time frames. In January 2000, the DNFSB issued Recommendation 2000-1, which stated the need for LANL to repackage 'about one ton of plutonium metal and oxide,' declared excess to Defense Program (DP) needs. The DNFSB recommended that LANL 'stabilize and seal within welded containers with an inert atmosphere the plutonium oxides ... which are not yet in states conforming to the long-term storage envisaged by DOE-STD-3013,' and that they '... enclose existing and newly-generated legacy plutonium metal in sealed containers with an inert atmosphere,' and 'remediate and/or safely store the various residues.' Recommendation 2000-1, while adding to the number of items needing remediation, also reiterated the need to address remaining items from 1994-1 in a timely fashion. Since timetables slipped, the DNFSB recommended that the Complex 'prioritize and schedule tasks according to the consideration of risks.' In March 2005, the DNFSB issued Recommendation 2005-1. This recommendation addresses the need for a consistent set of criteria across the DOE complex for the interim storage of nuclear material packaged outside an engineered barrier. The Department of Energy (DOE) approved and issued on March 7, 2008, DOE M 441.1-1, Nuclear Material Packaging Manual [hereafter referred to as Manual] to address this recommendation, and a Prioritization Methodology as a complex-wide requirement for the packaging of nuclear material outside an engineered barrier. The Manual establishes 'technically justified criteria' for packages in order to ensure safe interim storage and handling outside an engineered barrier. The Prioritization Methodology establishes a risk-based procedure for identifying the order to repackage that would most efficiently reduce the overall risk. It is a logical extension of the work performed to meet the two earlier DNFSB recommendations to include all materials stored outside of engineered barriers, i.e., not just excess materials. LANL will continue to work all aspects of a comprehensive Implementation Plan to d monstrate all aspects of compliance with the Manual. Assessment of materials in nonstandard containers utilizing a risk based approach, repackaging up to 400 containers/year; activities include reprocessing of items to allow container consolidation and subsequent increase in vault capacity. Continued efforts in establishing and implementing a Surveillance and Maintenance Program for current Hagans and for the NG SNMCSs supported by a database for packaging and surveillance. Elastomer aging studies for the NG SNMCs will continue to justify extending the design life well beyond the currently specified five years. First production with containers available for use anticipated in June 2010. LANL will continue to define schedule and resources to meet these objectives.

A standard for measuring metadata quality in spectral libraries  

NASA Astrophysics Data System (ADS)

A standard for measuring metadata quality in spectral libraries Barbara Rasaiah, Simon Jones, Chris Bellman RMIT University Melbourne, Australia barbara.rasaiah@rmit.edu.au, simon.jones@rmit.edu.au, chris.bellman@rmit.edu.au ABSTRACT There is an urgent need within the international remote sensing community to establish a metadata standard for field spectroscopy that ensures high quality, interoperable metadata sets that can be archived and shared efficiently within Earth observation data sharing systems. Metadata are an important component in the cataloguing and analysis of in situ spectroscopy datasets because of their central role in identifying and quantifying the quality and reliability of spectral data and the products derived from them. This paper presents approaches to measuring metadata completeness and quality in spectral libraries to determine reliability, interoperability, and re-useability of a dataset. Explored are quality parameters that meet the unique requirements of in situ spectroscopy datasets, across many campaigns. Examined are the challenges presented by ensuring that data creators, owners, and data users ensure a high level of data integrity throughout the lifecycle of a dataset. Issues such as field measurement methods, instrument calibration, and data representativeness are investigated. The proposed metadata standard incorporates expert recommendations that include metadata protocols critical to all campaigns, and those that are restricted to campaigns for specific target measurements. The implication of semantics and syntax for a robust and flexible metadata standard are also considered. Approaches towards an operational and logistically viable implementation of a quality standard are discussed. This paper also proposes a way forward for adapting and enhancing current geospatial metadata standards to the unique requirements of field spectroscopy metadata quality.

Applicability of ISO standard methods to vibration measurements at high frequencies and high accelerations  

NASA Astrophysics Data System (ADS)

New and revised laser methods and techniques developed by national metrology institutes and by leading manufacturers in the past two decades have been swiftly specified as standard methods in the ISO 16063 series of international document standards. The first international standard for the calibration of laser vibrometers, ISO 16063-41:2011, specifies the instrumentation and procedures for performing primary and secondary calibrations of rectilinear laser vibrometers in "typical" ranges of frequency (0,4 Hz to 50 kHz) and other conditions, with "typical attainable uncertainties" (0,25% to 5% for different specified conditions). This allows the specified standard methods to apply with refined techniques and procedures achieving even wider measurement ranges and smaller measurement uncertainties than that specified in the ISO standard. Recent theoretical and experimental investigations demonstrate the applicability of the standardized interferometric methods up to frequencies considerably higher than 50 kHz if measurable vibration amplitudes are generated. Sinusoidal vibration was generated by a piezoelectric actuator at frequencies between 63 kHz and 347 kHz and the displacement was measured by different interferometric standard methods applied simultaneously. Their results differed by less than 1% from each other. From the analysis of the results it is expected that frequencies up to 500 kHz are achievable.

Status report on standard-setting work in the area of environmental radioactivity measurement.  

PubMed

Environmental assessment studies are regularly commissioned to study the impact of radioactive substances on the environment and the public, in response to concern about the presence of such substances. The credibility of such studies relies on the quality and reliability of radionuclide analysis as well as the sample representativity of the radiological situation. The recent expansion from national stakeholders to those involving other states requires that activity measured in effluents or environmental samples in a country are reliable and reproducible so as to be accepted by all states potentially concerned by regional contamination. The standard-setting approach, based on consensus, seemed to lend itself to a settlement of technical aspects of potential dispute. This document describes standardization organizations, French and international, the standards published, as well as standardization work under way on the measurement of radionuclides found in environmental matrices.

Measurement of Microchannel Fluidic Resistance with a Standard Voltage Meter  

PubMed Central

A simplified method for measuring the fluidic resistance (Rfluidic) of microfluidic channels is presented, in which the electrical resistance (Relec) of a channel filled with a conductivity standard solution can be measured and directly correlated to Rfluidic using a simple equation. Although a slight correction factor could be applied in this system to improve accuracy, results showed that a standard voltage meter could be used without calibration to determine Rfluidic to within 12% error. Results accurate to within 2% were obtained when a geometric correction factor was applied using these particular channels. When compared to standard flow rate measurements, such as meniscus tracking in outlet tubing, this approach provided a more straightforward alternative and resulted in lower measurement error. The method was validated using 9 different fluidic resistance values (from ~40 – 600 kPa s mm?3) and over 30 separately fabricated microfluidic devices. Furthermore, since the method is analogous to resistance measurements with a voltage meter in electrical circuits, dynamic Rfluidic measurements were possible in more complex microfluidic designs. Microchannel Relec was shown to dynamically mimic pressure waveforms applied to a membrane in a variable microfluidic resistor. The variable resistor was then used to dynamically control aqueous-in-oil droplet sizes and spacing, providing a unique and convenient control system for droplet-generating devices. This conductivity-based method for fluidic resistance measurement is thus a useful tool for static or real-time characterization of microfluidic systems.

External Raman standard for absolute intensity and concentration measurements  

NASA Astrophysics Data System (ADS)

A new method of calibrating Raman intensities is described, which uses a sapphire window as an external intensity standard. This method overcomes problems often encountered using conventional internal standards techniques, resulting either from refractive index differences or chemical interactions of the standard with the sample. The new method is demonstrated by measuring solution concentrations and Raman cross sections in various liquids. Concentration measurements are performed using the second derivative variance minimization (SDVM) algorithm to simultaneously subtract the sapphire window spectrum, normalize the solution spectral intensity and quantify solute concentration. The absolute Raman cross sections of several pure liquids were determined by comparing intensities of the sapphire-normalized Raman bands to that of benzene and other liquids whose Raman cross sections are known.

Quantum metrology. Optically measuring force near the standard quantum limit.  

PubMed

The Heisenberg uncertainty principle sets a lower bound on the noise in a force measurement based on continuously detecting a mechanical oscillator's position. This bound, the standard quantum limit, can be reached when the oscillator subjected to the force is unperturbed by its environment and when measurement imprecision from photon shot noise is balanced against disturbance from measurement back-action. We applied an external force to the center-of-mass motion of an ultracold atom cloud in a high-finesse optical cavity and measured the resulting motion optically. When the driving force is resonant with the cloud's oscillation frequency, we achieve a sensitivity that is a factor of 4 above the standard quantum limit and consistent with theoretical predictions given the atoms' residual thermal disturbance and the photodetection quantum efficiency.

The regulation of protein content and quality in national and international food standards.  

PubMed

Food regulation aims to protect public health through a safe and nutritious food supply produced by a compliant food industry. Food standards of developed countries generally do not regulate protein content or protein quality because the risk of dietary protein inadequacy in their national populations is very low. Protein is nevertheless regulated for reasons of product quality or protein labelling or to minimise assessed health risks associated with consumption of certain animal- and vegetable-protein foods; analogue products that extend or simulate commonly available animal-protein foods; and special purpose foods such as infant formula and foods, supplementary and medical foods, and foods for weight loss. The extent and approach to protein regulation varies greatly among jurisdictions but where it occurs, it is applied through minimum and sometimes maximum limits on protein content or quality measures or both using an inter-related approach. Protein quality measures range from amino acid profiles and digestibility corrected scores to protein rating, a rat bioassay and reference proteins not further described. Regulatory methods for protein quality determination are referenced to the published scientific literature or developed nationally. Internationally, the Codex Alimentarius regulates the protein content and quality of some foods. The Codex approach varies according to the food but is similar to the approaches used in national and regional food regulation. This paper provides a comparison of the regulation of protein in foods using examples from the food regulations of Australia New Zealand, Canada, the European Union, the United States of America and the Codex Alimentarius.

Method for continuous end standard measurement utilizing laser interferometer  

NASA Astrophysics Data System (ADS)

For dimensional researches and applications, the end standard measurements are the popular subjects in high precision standard systems or instruments. In general, the gauge blocks are the representative of the end standards. The universal measurement machines (UMM) are usually utilized for the dimensional length of gauge blocks. However, for measuring the dimensional lengths of test gauge blocks (TGBs), they should be compared with the same lengths of the master gauge blocks (MGBs). Thus, there are different lengths of the MGBs needed to be prepared and the measuring procedures are usually very time consuming. In order to lower the cost of procurement and maintenance of MGBs, a continuous end standard measurement system (CESMS) was built for many different test ranges of TGBs. The features of the CESMS included at least one gauge block, the LVDT probes for positioning, the real lengths of the TGBs measured from the display value of the laser interferometer, and total procedures controlled by automation software. All of these parts were integrated onto a large platform and its moving carriage could travel up to 1.2-meter in distance. Within these ranges, the CESMS could measure different dimensional lengths of the TGBs and many pieces at the same time. The CESMS utilized the laser interferometer to acquire the accurate display values between two ends when the LVDT probe was touched and triggered the automation software to record. Owing to the recommended radiation of laser head, the CESMS could be traced to the meter, SI unit. Furthermore, the experiment results showed that the comparison results of certificated gauge block at 800 mm suited for calibration certificate by PTB.

A Standardized measure: NDNQI nursing care hours indicator.  

PubMed

Although nursing care hours (NCH) is commonly used to examine factors related to adverse events among inpatients, the reliability of the NCH measure has rarely been examined. This study assessed the reliability of NCH data from the National Database of Nursing Quality Indicators® by estimating intraclass correlation coefficients (ICCs) with data from the California Office for Statewide Health Planning and Development. Hospital-level aggregated NCH data for critical care units were linked from each of the databases for 48 California hospitals matched in the two databases. Estimated ICCs were .96 for registered nurse (RN) hours and .72 for non-RN hours. Findings provide evidence that NCH data of the national database were substantially reliable for use in national comparable benchmarking reports for hospitals' quality improvement activities and research.

Standardization of xenon-127 and measurement of photon emission intensities.  

PubMed

Xenon-127 was standardized by internal gas counting using three proportional counters in a differential arrangement to eliminate edge effects. The detection efficiency of the proportional counters was calculated by considering the cascade of events following the electron capture and associated gamma transitions. Activity per unit volume was measured with 0.7% relative standard uncertainty. Gamma-ray spectrometry was performed and absolute photon emission intensities were derived. This study shows that (127)Xe could be a surrogate for (133)Xe for the calibration of remote radio-xenon monitoring stations. PMID:24360861

The evaluation of hospital laboratory information management systems based on the standards of the American National Standard Institute  

PubMed Central

Introduction: Nowadays, modern laboratories are faced with a huge volume of information. One of the goals of the Laboratory Information Management System (LIMS) is to assist in the management of the information generated in the laboratory. This study intends to evaluate the LIMS based on the standards of the American National Standard Institute (ANSI). Materials and Methods: This research is a descriptive–analytical study, which had been conducted in 2011, on the LIMSs in use, in the teaching and private hospitals in Isfahan. The data collecting instrument was a checklist, which was made by evaluating three groups of information components namely: ‘System capabilities’, ‘work list functions,’ and ‘reporting’ based on LIS8-A. Data were analyzed using the SPSS 20. Data were analyzed using (relative) frequency, percentage. To compare the data the following statistical tests were used: Leven test, t-test, and Analysis of Variance (ANOVA). Results: The results of the study indicated that the LIMS had a low conformity (30%) with LIS8-A (P = 0.001), with no difference between teaching and private hospitals (P = 0.806). The ANOVA revealed that in terms of conformity with the LIS8-A standard, there was a significant difference between the systems produced by different vendors (P = 0.023). According to the results, a Kowsar system with more than %57 conformity in the three groups of information components had a better conformity to the standard, compared to the other systems. Conclusions: This study indicated that none of the LIMSs had a good conformity to the standard. It seems that system providers did not pay sufficient attention to many of the information components required by the standards when designing and developing their systems. It was suggested that standards from certified organizations and institutions be followed in the design and development process of health information systems.

Standardization of Solar Mirror Reflectance Measurements - Round Robin Test: Preprint  

SciTech Connect

Within the SolarPaces Task III standardization activities, DLR, CIEMAT, and NREL have concentrated on optimizing the procedure to measure the reflectance of solar mirrors. From this work, the laboratories have developed a clear definition of the method and requirements needed of commercial instruments for reliable reflectance results. A round robin test was performed between the three laboratories with samples that represent all of the commercial solar mirrors currently available for concentrating solar power (CSP) applications. The results show surprisingly large differences in hemispherical reflectance (sh) of 0.007 and specular reflectance (ss) of 0.004 between the laboratories. These differences indicate the importance of minimum instrument requirements and standardized procedures. Based on these results, the optimal procedure will be formulated and validated with a new round robin test in which a better accuracy is expected. Improved instruments and reference standards are needed to reach the necessary accuracy for cost and efficiency calculations.

Mobile Nondestructive Assay (NDA) Measurements of Standard Waste Boxes (SWB)  

SciTech Connect

A mobile NDA system was composed and qualified for Safeguards measurements of multiple standard waste boxes (SWB) generated as a result of clean-out activities at Hanford’s Plutonium Finishing Plant (PFP). The system included a neutron slab counter and high purity germanium (HPGe) detector. PC/FRAM software was used to determine the isotopic composition of plutonium residue contained in the waste in order to interpret two independent measurement results provided by total neutron counting and gamma energy analysis (GEA). The measurement procedure developed to estimate transuranic (TRU) content of boxes was based on assumptions about characteristics of the matrix and material distribution. The neutron slab counter was calibrated with various plutonium working standards that were placed in a surrogate SWB specifically made to simulate miscellaneous waste debris. Transmission measurements with a californium source were used to correct for the matrix effects. An In-Situ Object Counting System (ISOCS) was used to acquire spectra from SWBs and ISOCS software was applied to generate the efficiency curve of the HPGe detector. Infinite energy extrapolation was introduced to correct GEA results for self-attenuation. The gamma and neutron results obtained on multiple SWBs are compared and discussed in the paper. Revised measurement positions for the detector and the transmission source are also suggested based on experience gained during the measurements.

Implementation of ISO 10110 optics drawing standards for the National Ignition Facility

The National Ignition Facility (NIF) project elected to implement ISO 10110 standard for the specifications of NIF optics drawings in 1996. More than 7,000 NIF large optics and 20,000 NIF small optics will be manufactured based on ISO 10110 indications. ISO 10110 standard meets many of the needs of the NIF optics specifications. It allows the optical engineer to quantify and clearly communicate the desired optical specifications. While no single drawing standard specifies all the requirements of high energy laser system, a combination of ISO 10110 standard with detailed notes make it possible to apply international drawing standards to the NIF laser system. This paper will briefly describe LLNL's interpretation and implementation of the ISO 10110 drawing standard, present some examples of NIF optics drawings, and discuss pros and cons of the indications from the perspective of this application. Emphasis will be given to the surface imperfection specifications, known as 5/, for the NIF optics.

Standards Development for the U.S. National Geologic Map Database  

NASA Astrophysics Data System (ADS)

The U.S. Geological Survey and the Nation's state geological surveys (under authority of the Association of American State Geologists) are mandated by Congress to provide a National Geologic Map Database (NGMDB) of standardized geoscience information that can be used to address societal issues and improve our base of scientific knowledge. Over the past decade, the NGMDB project has addressed its mandate by providing: 1) basic information and services that enable users to find available geoscience information; 2) a venue for development of community-based standards that are promoting broader public use of geoscience map information and more effective interoperability among the Nation's geological surveys; and 3) a research and development environment in which we are building a distributed database system to archive and serve the Nation's geologic map information. The NGMDB is addressing its mission in an incremental fashion, by building "support" databases and standards, and by working toward the long-term goal of the distributed system. Products currently available to serve the geoscience community and the general public are: the U.S. Geologic Names Lexicon ("GEOLEX"), which is a standard reference for the Nation's stratigraphic nomenclature; the Geoscience Map Catalog and Image Library, which helps people find and view 70,000 published geoscience maps and related products; and various standards, which are the subject of this paper. In cooperation with other U.S. and Canadian agencies, and with the IUGS Commission for the Management and Application of Geoscience Information ("CGI"), the NGMDB project is defining standards that include: a science terminology; a conceptual data model; a physical implementation of the data model in ArcGIS; a FGDC-endorsed standard for map symbols and patterns and for descriptions of locational accuracy of geologic features in the field; and a GML-based exchange standard to promote interoperability among data providers to the NGMDB. These standards form the basis for the design of our online map database. Because it will be a distributed system managed among more than 50 agencies (each with different personnel skills, organizational culture, hardware and software platforms, funding constraints, and public and private user needs), the standards must accommodate these differences and yet enable the NGMDB database to function as if it were a single entity. The standards are now being tested in the NGMDB prototype database; this testing is aided by our new data-entry tool and ArcGIS implementation, which will allow our project partners to evaluate the database structure and science terminology and to make recommendations for improvement. Information and links to NGMDB databases and standards are available at http://ngmdb.usgs.gov/Info/.

Mobility measurements with a standard contact resistance pattern  

NASA Astrophysics Data System (ADS)

The standard test pattern used for planar-contact resistance measurements yields values for normalized contact resistance, contact resistivity, and semiconductor sheet resistance. Application of a perpendicular magnetic field yields additional data, including bulk semiconductor mobility and sheet carrier concentration, and also the mobility of the material under the contact. This new technique is applied to a GaAs implanted layer designed for metal-semiconductor field-effect transistor (MESFET) applications. One advantage of the method is that a separate Hall-effect measurement is no longer necessary.

Under Section 61.94 of Title 40, Code of Federal Regulations (CFR), Part 61, Subpart H, ``National Emission Standards for Emissions of Radionuclides Other Than Radon From Department of Energy Facilities,`` each Department of Energy (DOE) facility must submit an annual report documenting compliance. This report addresses the Section 61.94 reporting requirements for operations at the Idaho National Engineering and Environmental Laboratory (INEEL) for calendar year (CY) 1996. The Idaho Operations Office of the DOE is the primary contact concerning compliance with the National Emission Standards for Hazardous Air Pollutants (NESHAPs) at the INEEL. For calendar year 1996, airborne radionuclide emissions from the INEEL operations were calculated to result in a maximum individual dose to a member of the public of 3.14E-02 mrem (3.14E-07 Sievert). This effective dose equivalent (EDE) is well below the 40 CFR 61, Subpart H, regulatory standard of 10 mrem per year (1.0E-04 Sievert per year).

Data format standard for sharing light source measurements  

NASA Astrophysics Data System (ADS)

Optical design requires accurate characterization of light sources for computer aided design (CAD) software. Various methods have been used to model sources, from accurate physical models to measurement of light output. It has become common practice for designers to include measured source data for design simulations. Typically, a measured source will contain rays which sample the output distribution of the source. The ray data must then be exported to various formats suitable for import into optical analysis or design software. Source manufacturers are also making measurements of their products and supplying CAD models along with ray data sets for designers. The increasing availability of data has been beneficial to the design community but has caused a large expansion in storage needs for the source manufacturers since each software program uses a unique format to describe the source distribution. In 2012, the Illuminating Engineering Society (IES) formed a working group to understand the data requirements for ray data and recommend a standard file format. The working group included representatives from software companies supplying the analysis and design tools, source measurement companies providing metrology, source manufacturers creating the data and users from the design community. Within one year the working group proposed a file format which was recently approved by the IES for publication as TM-25. This paper will discuss the process used to define the proposed format, highlight some of the significant decisions leading to the format and list the data to be included in the first version of the standard.

Multiple units of Standard Reference Materials (SRMs) 1566 Oyster Tissue, 1567 Wheat Flour, 1568 Rice Flour, and 1570 Trace Elements in Spinach, produced by the National Institute of Standards and Technology (NIST, then the National Bureau of Standards), were analyzed 17-20 years after the original certification dates and 12-15 years after the certificates became invalid. Instrumental neutron activation analysis and thermal neutron prompt gamma-ray activation analysis were used to measure mass fractions for 27 elements in these SRMs to revalidate them for use in quality assurance (QA) programs required for food analysis programs within the U.S. Food and Drug Administration. With the exception of Se in SRM 1567, all element mass fractions were in agreement with certified values and literature data. Some evidence of B loss from SRM 1568 was observed. These materials were judged to be suitable for continued use in QA programs. Findings showed that these matrixes exhibited stability of moisture, mass fraction, and weight basis for far longer (> or =15 years) than was indicated by the 5-year validity statement on the NIST Certificates of Analysis.

Evaluation of Vitamin D Standardization Program protocols for standardizing serum 25-hydroxyvitamin D data: a case study of the program's potential for national nutrition and health surveys12345  

PubMed Central

Background: The Vitamin D Standardization Program (VDSP) has developed protocols for standardizing procedures of 25-hydroxyvitamin D [25(OH)D] measurement in National Health/Nutrition Surveys to promote 25(OH)D measurements that are accurate and comparable over time, location, and laboratory procedure to improve public health practice. Objective: We applied VDSP protocols to existing ELISA-derived serum 25(OH)D data from the Irish National Adult Nutrition Survey (NANS) as a case-study survey and evaluated their effectiveness by comparison of the protocol-projected estimates with those from a reanalysis of survey serums by using liquid chromatography–tandem mass spectrometry (LC–tandem MS). Design: The VDSP reference system and protocols were applied to ELISA-based serum 25(OH)D data from the representative NANS sample (n = 1118). A reanalysis of 99 stored serums by using standardized LC–tandem MS and resulting regression equations yielded predicted standardized serum 25(OH)D values, which were then compared with LC–tandem MS reanalyzed values for all serums. Results: Year-round prevalence rates for serum 25(OH)D concentrations <30, <40, and <50 nmol/L were 6.5%, 21.9%, and 40.0%, respectively, via original ELISA measurements and 11.4%, 25.3%, and 43.7%, respectively, when VDSP protocols were applied. Differences in estimates at <30- and <40-nmol/L thresholds, but not at the <50-nmol/L threshold, were significant (P < 0.05). A reanalysis of all serums by using LC–tandem MS confirmed prevalence estimates as 11.2%, 27.2%, and 45.0%, respectively. Prevalences of serum 25(OH)D concentrations >125 nmol/L were 1.2%, 0.3%, and 0.6% by means of ELISA, VDSP protocols, and LC–tandem MS, respectively. Conclusion: VDSP protocols hold a major potential for national nutrition and health surveys in terms of the standardization of serum 25(OH)D data.

Assessing the Life Science Knowledge of Students and Teachers Represented by the K-8 National Science Standards  

PubMed Central

We report on the development of an item test bank and associated instruments based on the National Research Council (NRC) K–8 life sciences content standards. Utilizing hundreds of studies in the science education research literature on student misconceptions, we constructed 476 unique multiple-choice items that measure the degree to which test takers hold either a misconception or an accepted scientific view. Tested nationally with 30,594 students, following their study of life science, and their 353 teachers, these items reveal a range of interesting results, particularly student difficulties in mastering the NRC standards. Teachers also answered test items and demonstrated a high level of subject matter knowledge reflecting the standards of the grade level at which they teach, but exhibiting few misconceptions of their own. In addition, teachers predicted the difficulty of each item for their students and which of the wrong answers would be the most popular. Teachers were found to generally overestimate their own students’ performance and to have a high level of awareness of the particular misconceptions that their students hold on the K–4 standards, but a low level of awareness of misconceptions related to the 5–8 standards.

Reference standard for carbonaceous impurity measurements in carbon nanotubes  

NASA Technical Reports Server (NTRS)

Near-infrared spectroscopy is a convenient tool for measuring nanotube / carbonaceous impurities ratios in carbon nanotube samples. These measurements are based on separation of contributions from nanotubes and impurities to the near-infrared absorption of samples dispersed in DMF, and sample purity is expressed relative to some reference sample. In the current work we produced a reference standard for NIR measurements using purified laser nanotubes. The sample was oxidized slowly using a Temperature Programmed Oxidation (TPO) setup in 2% oxygen / 98 % helium atmosphere. In these conditions, the sample oxidized in several steps, which were attributed to carbonaceous impurities, nanotubes and graphitic shells based on TEM and Raman observations. Stopping oxidation at 625 C (this temperature is sample-specific) allowed us to produce a sample with no carbonaceous impurities and well-defined ratio of nanotubes, graphite and metal catalyst. Since carbonaceous impurities no longer hold nanotubes and particles together, further centrifuging allowed us to remove particles and use this sample as a reference standard in NIR measurements.

OPTOTRAK Measurement of the Quadriceps Angle Using Standardized Foot Positions  

PubMed Central

Objective: While there is evidence to suggest that the magnitude of the quadriceps (Q) angle changes with alterations in foot position, a detailed quantitative description of this relationship has not been reported. Our purpose was to determine the effect of varying foot placement on the magnitude of the Q angle. Design and Setting: A mixed between-within, repeated-measures design was used to compare Q angles derived under static weight-bearing conditions with the feet positioned in self-selected versus standardized stance positions. Subjects: Twenty healthy young-adult men and women with no history of acute injury to or chronic dysfunction of the lower limbs. Measurements: We placed light-emitting diodes bilaterally on the left and right anterior superior iliac spines, the tibial tuberosities, and the midpoints of the patellae to bilaterally define the Q angles. An OPTOTRAK motion-measurement system was used to capture x,y coordinate data at a sampling rate of 60 Hz. These data were subsequently filtered and used to calculate the magnitude of the left and right Q angles. Results: A repeated-measures analysis of variance revealed that when measured statically, Q angles differed significantly between stance positions (P < .001) and limbs (P < .05). Depending on the stance adopted, mean Q angles varied from 7.2° to 12.7° and 11.0° to 16.1° in the left and right lower limbs, respectively. Q-angle measurements taken in conjunction with the Romberg foot position most closely resembled those gathered with the feet in a self-selected stance (Pearson r = 0.86 to 0.92). Conclusions: Q-angle magnitude varies with changes in foot position, increasing or decreasing as the foot rotates internally or externally, respectively. These data demonstrate the need for a standardized foot position for Q-angle measurements.

Measures of Inequality: Application to Happiness in Nations  

PubMed Central

What is a good measure for happiness inequality? In the context of this question, we have developed an approach in which individual happiness values in a sample are considered as elements of a set and inequality as a binary relation on that set. The total number of inequality relations, each weighed by the distance on the scale of measurement between the pair partners, has been adopted as an indicator for the inequality of the distribution as a whole. For models in which the happiness occurs as a continuous latent variable, an analogous approach has been developed on the basis of differentials. In principle, this fundamental approach results in a (zero) minimum value, and, more importantly, also in a maximum value. In the case where happiness is measured using a k-points scale, the maximum inequality is obtained if all ½N sample members select the lowest possible rating (Eq. 1) and the other ½N the highest possible one (k). This finding even applies to the truly ordinal case, i.e., if the distances between the successive ratings on the scale are unknown. It is, however, impossible to quantify the inequality of some measured sample distribution, unless all distances of the k categories of the scale of measurement are known or at least estimated, either on an empirical basis or on the basis of assumptions. In general, the numerical application of the method to continuous distributions is very complicated. An exploration on the basis of a relatively simple model with a linear probability density function suggests that the inequality of a beta probability distribution with shape parameters a and b increases as the value of these parameters decreases. A contour plot, obtained by numerical integration, demonstrates this relationship in a quantitative way. This approach is applicable to judge the aptness of common statistics of dispersion, among which the standard deviation and the Gini coefficient. The former is shown to be more appropriate than the latter for measuring inequality of happiness within nations.

National culturally and linguistically appropriate services standards--mandates or not?  

PubMed

The U.S. Department of Health and Human Services' Office of Minority Health (OMH) promotes National Standards for Culturally and Linguistically Appropriate Services. According to the Office, four of these standards are "mandates" that are considered federal requirements for all recipients of federal funds. These standards focus on increasing language access to health care services for limited English proficient (LEP) people. Relying on this statement, multiple organizations, scholars and advocates promote these mandates in their communities. However, the DHHS Office of Inspector General stated in a 2010 report that these standards are only voluntary and not mandated. This contradiction deserves the attention of public health advocates for LEP people. This article seeks to clarify this contradiction so that public health advocates and experts can provide accurate information to people they serve and consider whether they should work with to develop truly mandatory language access standards as a condition of federal funding.

Harmonizing the American National Standards Institute (ANSI) and International Electrotechnical Commission (IEC) sound level meter specification standards  

NASA Astrophysics Data System (ADS)

It has been over 20 years since the last major revision of the American National Standard Specification for Sound Level Meters, S1.4-1983 (R2002). This is the most extensively referenced ANSI acoustical standard, with wide application to architectural acoustics, soundscapes, environmental noise, and hearing conservation. A new revision is proposed that conforms as closely as possible to the recently developed International Electrotechnical Commission Standard for Electroacoustics-Sound Level Meters Part 1: Specifications, IEC 61672-1 (2002-05). This proposed revision represents an improvement over ANSI S1.4-1983, particularly in its frequency response tolerance limits at high frequencies, and impulse (toneburst) response. Also, it incorporates the high-frequency electrical design goals and tolerance limits for A-weighted response that were specified in Amendment S1.4A-1985, and it maintains the more restrictive low-frequency tolerance limits of the earlier (1983) specification, compared to IEC 61672-1. The proposed revision maintains the laboratory precision Type 0 specification, which is absent in IEC 61672-1, while incorporating the specifications for integrating-averaging sound level meters previously given in ANSI S1.43-1997. Sound level meters which meet the Type 1 and Type 2 specification requirements, respectively, in this S1.4 revision will also meet the Class 1 and Class 2 specification requirements of 61672-1.

The Orbiting Standards Platform (OSP) is a proposed satellite dedicated to performing RF measurements on space communications systems. It would consist of a quasi-geostationary spacecraft containing an ensemble of calibrated RF sources and field strength meters operating in several microwave bands, and would be capable of accurately and conveniently measuring critical earth station and satellite RF performance parameters, such as EIRP, gain, figure of merit (G/T), crosspolarization, beamwidth, and sidelobe levels. The feasibility and utility of the OSP concept has been under joint study by NASA, NBS, Comsat and NTIA. A survey of potential OSP users was conducted by NTIA as part of this effort. The response to this survey, along with certain trends in satellite communications system design, indicates a growing need for such a measurement service.

Error analysis for NMR polymer microstructure measurement without calibration standards.  

PubMed

We report an error analysis method for primary analytical methods in the absence of calibration standards. Quantitative (13)C NMR analysis of ethylene/1-octene (E/O) copolymers is given as an example. Because the method is based on a self-calibration scheme established by counting, it is a measure of accuracy rather than precision. We demonstrate it is self-consistent and neither underestimate nor excessively overestimate the experimental errors. We also show the method identified previously unknown systematic biases in a NMR instrument. The method can eliminate unnecessary data averaging to save valuable NMR resources. The accuracy estimate proposed is not unique to (13)C NMR spectroscopy of E/O but should be applicable to all other measurement systems where the accuracy of a subset of the measured responses can be established.

Standardized DOE Spent Nuclear Fuel Canister and Transportation System for Shipping to the National Repository  

SciTech Connect

The U.S.Department of Energy’s (DOE) National Spent Nuclear Fuel Program (NSNFP), located at the Idaho National Engineering and Environmental Laboratory (INEEL), has been chartered with the responsibility for developing spent nuclear fuel (SNF) standardized canisters and a transportation cask system for shipping DOE SNF to the national repository. The mandate for this development is outlined in the Memorandum of Agreement for Acceptance of Department of Energy Spent Nuclear Fuel and High-Level Radioactive Waste that states, “EM shall design and fabricate … DOE SNF canisters for shipment to RW.” (1) It also states, “EM shall be responsible for the design, NRC certification, and fabrication of the transportation cask system for DOE SNF canisters or bare DOE SNF in accordance with 10 CFR Part 71.” (2) In fulfillment of these requirements, the NSNFP has developed four SNF standardized canister configurations and has conceptually designed a versatile transportation cask system for shipping the canisters to the national repository.1 The standardized canister sizes were derived from the national repository waste package design for co-disposal of SNF with high-level waste (HLW). One SNF canister can be placed in the center of the waste package or one can be placed in one of five radial positions, replacing a HLW canister. The internal cavity of the transportation cask was derived using the same logic, matching the size of the internal cavity of the waste package. The size of the internal cavity for the transportation cask allows the shipment of multiple canister configurations with the application of a removable basket design. The standardized canisters have been designed to be loaded with DOE SNF, placed into interim storage, shipped to the national repository, and placed in a waste package without having to be reopened. Significant testing has been completed that clearly demonstrates that the standardized canisters can safely achieve their intended design goals. The transportation cask system will include all of the standard design features, with the addition of dual containment for the shipment of failed fuel. The transportation cask system will also meet the rigorous licensing requirements of the Nuclear Regulatory Commission (NRC) to ensure that the design and the methods of fabrication employed will result in a shipping cask that will safely contain the radioactive materials under all credible accident scenarios. The standardization of the SNF canisters and the versatile design of the transportation cask system will eliminate a proliferation of designs and simplify the operations at the user sites and the national repository.

Measuring Retention in HIV Care: The Elusive Gold Standard  

PubMed Central

Background Measuring retention in HIV primary care is complex as care includes multiple visits scheduled at varying intervals over time. We evaluated six commonly used retention measures in predicting viral load (VL) suppression and the correlation among measures. Methods Clinic-wide patient-level data from six academic HIV clinics were used for 12-months preceding implementation of the CDC/HRSA Retention in Care intervention. Six retention measures were calculated for each patient based upon scheduled primary HIV provider visits: count and dichotomous missed visits, visit adherence, 6-month gap, 4-month visit constancy, and the HRSA HAB retention measure. Spearman correlation coefficients and separate unadjusted logistic regression models compared retention measures to one another and with 12-month VL suppression, respectively. The discriminatory capacity of each measure was assessed with the c-statistic. Results Among 10,053 patients, 8,235 (82%) had 12-month VL measures, with 6,304 (77%) achieving suppression (VL<400 c/mL). All six retention measures were significantly associated (P<0.0001) with VL suppression (OR;95%CI, c-statistic): missed visit count (0.73;0.71–0.75,0.67), missed visit dichotomous (3.2;2.8–3.6,0.62), visit adherence (3.9;3.5–4.3,0.69), gap (3.0;2.6–3.3,0.61), visit constancy (2.8;2.5–3.0,0.63), HRSA HAB (3.8;3.3–4.4,0.59). Measures incorporating “no show” visits were highly correlated (Spearman coefficient=0.83–0.85), as were measures based solely upon kept visits (Spearman coefficient=0.72–0.77). Correlation coefficients were lower across these two groups of measures (Range=0.16–0.57). Conclusions Six retention measures displayed a wide range of correlation with one another, yet each measure had significant association and modest discrimination for VL suppression. These data suggest there is no clear gold standard, and that selection of a retention measure may be tailored to context.

Rotating pressure measurement system using an on board calibration standard  

NASA Technical Reports Server (NTRS)

A computer-controlled multichannel pressure measurement system was developed to acquire detailed flow field measurements on board the Large Low Speed Centrifugal Compressor Research Facility at the NASA Lewis Research Center. A pneumatic slip ring seal assembly is used to transfer calibration pressures to a reference standard transducer on board the compressor rotor in order to measure very low differential pressures with the high accuracy required. A unique data acquisition system was designed and built to convert the analog signal from the reference transducer to the variable frequency required by the multichannel pressure measurement system and also to provide an output for temperature control of the reference transducer. The system also monitors changes in test cell barometric pressure and rotating seal leakage and provides an on screen warning to the operator if limits are exceeded. The methods used for the selection and testing of the the reference transducer are discussed, and the data acquisition system hardware and software design are described. The calculated and experimental data for the system measurement accuracy are also presented.

Modeling the wet bulb globe temperature using standard meteorological measurements.  

PubMed

The U.S. Army has a need for continuous, accurate estimates of the wet bulb globe temperature to protect soldiers and civilian workers from heat-related injuries, including those involved in the storage and destruction of aging chemical munitions at depots across the United States. At these depots, workers must don protective clothing that increases their risk of heat-related injury. Because of the difficulty in making continuous, accurate measurements of wet bulb globe temperature outdoors, the authors have developed a model of the wet bulb globe temperature that relies only on standard meteorological data available at each storage depot for input. The model is composed of separate submodels of the natural wet bulb and globe temperatures that are based on fundamental principles of heat and mass transfer, has no site-dependent parameters, and achieves an accuracy of better than 1 degree C based on comparisons with wet bulb globe temperature measurements at all depots.

The Space Weather Compendium: Trials and Tribulations to Aligning Existing Lessons with the National Standards  

NASA Astrophysics Data System (ADS)

A major challenge facing successful programs in solar and space physics education is finding appropriate standards-based lessons at the elementary, middle and high school levels. High-quality lessons follow a specific set of criteria to facilitate science literacy in solar and space physics within a defined scope and sequence. Without this, students fail to grasp the interconnectedness of the science and lack a sense of the bigger picture. Because teachers often have limited familiarity with the science of solar and space physics, finding solar and space physics lessons that align with state and national standards can be a challenge. CU-LASP's Space Weather Compendium is a compilation of existing lessons and activities from a wide range of sources that we have aligned to national and Colorado state standards and placed within a grade- appropriate scope and sequence. Here, we explore the challenges involved in creating a compendium of activities that align with national standards, and how to successfully meet space physics literacy goals at the elementary, middle and high school levels. In addition, we outline the additional supporting materials that we have found teachers need in order to bring the excitement of solar and space physics into the classroom effectively.

National Science Education Standards as a Catalyst for Change: The Essential Role of Professional Development  

NSDL National Science Digital Library

Standards have become a part of the educational landscape. In this chapter, we survey the origins of national standards; reflect on their power, in particular those in science education; and examine the role professional development must play if standards are to realize their potential to truly transform education. The link between standards and professional development is essential: Knowing where one needs to go is only the first step. Building the capacity for continuous learning for all students--a capacity needed to take us well into the 21st century--must follow. This free selection also includes a Foreword, Preface, an About the Editors page, the Table of Contents, and an Introduction section.

Dying in two acute hospitals: would usual care meet Australian national clinical standards?  

PubMed

The Australian Commission for Quality and Safety in Health Care (ACQSHC) has articulated 10 clinical standards with the aim of improving the consistency of quality healthcare delivery. Currently, the majority of Australians die in acute hospitals. But despite this, no agreed standard of care exists to define the minimum standard of care that people should accept in the final hours to days of life. As a result, there is limited capacity to conduct audits that focus on the gap between current care and recommended care. There is, however, accumulating evidence in the end of life literature to define which aspects of care are likely to be considered most important to those people facing imminent death. These themes offer standards against which to conduct audits. This is very apt given the national recommendation that healthcare should be delivered in the context of considering people's wishes while always treating people with dignity and respect.

Calibration techniques for extensometry: Possible standards of strain measurement  

SciTech Connect

The search for an adequate reference strain measuring technique for use in the materials testing laboratory has spanned several decades. Early methods relied on properly calibrated extensometers. Two examples are Tuckerman's Optical Strain Gage and Bergqvist's highly refined inductive and strain gage based extensometers. Length standards were used to calibrate these devices. Initially, mechanical displacement mechanisms were used as extensometer checking devices, but with the advent of lasers, the Michelson interferometer has become a dominant displacement measuring tool. Advances in stabilizing hardware and electronic detectors have led to the availability of Michelson systems with a resolution better than 5 nm. Microelectronic manufacturing techniques have been used to replicate the entire Michelson systems on a silicon ship. Advances in detector technology have also led to interferometric linear encoders with resolutions commensurate to classical interferometers. New techniques are being developed that can report strain and do not require initial calibration by displacement measuring instruments. This paper reviews some of the more interesting approaches from the past, analyzes some current methods being investigated, and comments on possibilities for the future concerning the difficult task of finding a suitable calibration technique for use with strain measuring devices.

Most sexually transmitted infections (STIs) are associated with increased risk of HIV transmission. The draft Scottish Sexual Health Strategy (2003) proposed that 'HIV testing [should be] offered to all GUM clinic attendees not known to be HIV infected who present with a new STI. ... Reasons for non-uptake should be recorded.' We performed a national audit comparing practice in Scottish genitourinary (GU) medicine services against these standards. The results show that practice is highly variable but overall in 2004 Scottish GU medicine clinics were failing to meet the strategy standard. PMID:16981318

Applying IEEE storage system management standards at the National Storage Laboratory  

SciTech Connect

Since its inception in 1990, the IEEE Storage System Standards Working Group has identified storage-system management as an area in need of further development The pressing need for standards in storage-system management arises from the requirement to exchange management information and to provide control in a consistent predictable manner between the components of a storage system. An appropriate set of management standards will allow multiple vendors to supply storage management subsystems or applications that are integral to or compatible with new storage systems conforming to future IEEE standards. An early, practical application of IEEE storage-system-management work is being pursued at the National Storage Laboratory (NSL), a recently-formed industrial collaboration at Lawrence Livermore National Laboratory. The NSL`s purpose is to develop advanced hardware and software technologies for high-performance, distributed storage systems. Since storage system management is of critical concern, it is being explored in depth at the NSL. Work was initiated to define basic management requirements and develop generalized graphical-user-interface tools using remote-procedure-call mechanisms to implement the NSL`s conceptual management framework. Several constraints were imposed on the development of early versions of this work to maintain compatibility with the NSL`s underlying UniTree-based software architecture and to provide timely prototypes and proof of concept. The project leverages the on-going standards work of the IEEE Storage System Standards Working Group (SSSWG) and also explores some of the relationships and interactions between IEEE storage-system management and more well known management methods for distributed systems and networks. It will have long term benefits by providing ``real-life`` storage-system-management requirements to the IEEE SSSWG for validation of evolving standards.

Measuring bioavailability: from a scientific approach to standard methods.  

PubMed

Biological effects are not related to the total concentration of a contaminant in the soil and soil-like materials. Organisms respond only to the fraction that is biologically available. The bioavailable fractions of contaminants are dependent on soil properties and various processes varying with time and on the behavior or the target organism. Bioavailability may be assessed in two complementary ways: (i) by chemical methods (e.g., extraction methods), which determine a defined available fraction of a well defined class of contaminants; and (ii) by biological methods, which expose organisms to soil or soil eluates to monitor effects. Although there is scientific discussion on the concept of bioavailability, the literature gives enough evidence to recognize bioavailability as a promising tool in risk assessment. A large number of methods are available. Under regulatory aspects of soil protection, a risk assessment should be based on the same common concept of determination and assessment of exposure and measuring and assessment of effects. A harmonized framework on bioavailability is necessary to promote the development and introduction of workable (international) standard methods to be used in soil and site assessment. The working group 'Bioavailability' of ISO/TC190-Soil Quality has developed a guidance document for development and selection of methods to assess bioavailability for different target species with regard to several classes of contaminants. The way to this standard, on the border of science and regulation, is described in this article. PMID:17766821

A reevaluation of the National Emission Standards for Hazardous Air Pollutants (NESHAP - 40 CFR 61, Subpart H) program at Sandia National Laboratories, New Mexico  

SciTech Connect

The initial National Emission Standards for Hazardous Air Pollutants (NESHAP - 40 CFR 61, Subpart H) Program at Sandia National Laboratories, New Mexico (SNL/NM) required: (1) continuous air monitoring of sources if the calculated effective dose equivalent (EDE) to the maximum exposed individual (MEI) was > 0.1 mrem/yr; (2) the determination of emissions based on measurements or measured parameters if the EDE to the MEI was < 0.1 mrem/yr; and (3) the calculation of worst case releases when the expected air concentrations were below detection limits using standard monitoring equipment. This conservative interpretation of the regulation guided SNL/NM to model, track, and trend virtually all emission sources with the potential to include any radionuclides. The level of effort required to implement these activities was independent of the EDE contributing from individual sources. A recent programmatic review found the NESHAP program to be in excess of the legal requirements. A further review found that, in summation, 13 of 16 radionuclide sources had a negligible impact on the final calculated EDE to the MEI used to demonstrate compliance at 20 separate on-site receptor locations. A reevaluation was performed to meet the legal requirements of 40 CFR 61, Subpart H, and still be reasonable and appropriate under the existing circumstances.

The U.S. Department of Energy, National Nuclear Security Administration Nevada Field Office (NNSA/NFO) operates the Nevada National Security Site (NNSS) and North Las Vegas Facility (NLVF). From 1951 through 1992, the NNSS was the continental testing location for U.S. nuclear weapons. The release of radionuclides from NNSS activities has been monitored since the initiation of atmospheric testing. Limitation to underground detonations after 1962 greatly reduced radiation exposure to the public surrounding the NNSS. After nuclear testing ended in 1992, NNSS radiation monitoring focused on detecting airborne radionuclides from historically contaminated soils. These radionuclides are derived from re-suspension of soil (primarily by wind) and emission of tritium-contaminated soil moisture through evapotranspiration. Low amounts of legacy-related tritium are also emitted to air at the NLVF, an NNSS support complex in North Las Vegas. To protect the public from harmful levels of man-made radiation, the Clean Air Act, National Emission Standards for Hazardous Air Pollutants (NESHAP) (Title 40 Code of Federal Regulations [CFR] Part 61 Subpart H) (CFR 2010a) limits the release of radioactivity from a U.S. Department of Energy (DOE) facility to that which would cause 10 millirem per year (mrem/yr) effective dose equivalent to any member of the public. This limit does not include radiation unrelated to NNSS activities. Unrelated doses could come from naturally occurring radioactive elements, from sources such as medically or commercially used radionuclides, or from sources outside of the United States, such as the damaged Fukushima nuclear power plant in Japan in 2011. NNSA/NFO demonstrates compliance with the NESHAP limit by using environmental measurements of radionuclide air concentrations at critical receptor locations on the NNSS (U.S. Environmental Protection Agency [EPA] and DOE 1995). This method was approved by the EPA for use on the NNSS in 2001 (EPA 2001a) and has been the sole method used since 2005. Six locations on the NNSS have been established to act as critical receptor locations to demonstrate compliance with the NESHAP limit. These locations are actually pseudo-critical receptor stations, because no member of the public actually resides at these onsite locations. Compliance is demonstrated if the measured annual average concentration is less than the NESHAP Concentration Levels (CLs) for Environmental Compliance listed in 40 CFR 61, Appendix E, Table 2 (CFR 2010a). For multiple radionuclides, compliance is demonstrated when the sum of the fractions (determined by dividing each radionuclide’s concentration by its CL and then adding the fractions together) is less than 1.0. In 2012, the potential dose from radiological emissions to air, resulting from both current and past NNSS activities, was well below the 10 mrem/yr dose limit. Air sampling data collected at all air monitoring stations had average concentrations of radioactivity that were a fraction of the CL values. Concentrations ranged from less than 0.5% to a maximum of 11.1% of the allowed NESHAP limit. Because the nearest member of the public resides about 9 kilometers from potential release points on the NNSS, dose to the public would be only a small fraction of the value measured on the NNSS. The potential dose to the public from NLVF emissions was also very low at 0.000024 mrem/yr, more than 400,000 times lower than the 10 mrem/yr limit.

Homogeneity evaluation of Chinese sugar carbon (CSC) standard for AMS 14C measurement  

NASA Astrophysics Data System (ADS)

The Chinese national radiocarbon standard Chinese Sugar Carbon (CSC), or often called the "Chinese Sucrose Charcoal," was investigated for its homogeneity and its suitability as a radiocarbon standard for Accelerator Mass Spectrometer (AMS). We randomly chose ten new CSC bottles and two opened bottles and measured their carbon isotope compositions. ?13C results obtained by Isotope Ratio Mass Spectrometer (IRMS) showed relatively large variation: from -15.9 to -22.2‰ with an average of -19.0 ± 1.2‰ (n = 49), indicating CSC grains in the mg range are not isotopically homogeneous. However, 14C results of CSC, expressed as Fraction Modern (FM), are well constrained to 2.4‰ after fractionation correction to -25‰. Measurements from all 12 bottles gave an average FM value of 1.3533 ± 0.0034 (n = 55). This value is about 7‰ higher that the FM value of 1.346 ± 0.002, converted from the originally reported R value of 1.362 ± 0.002 (n = 14, with ?13C of -19.32, n = 9) [1,2]. The R value of 1.362 is the ratio of 14C activity of CSC to 95% of OXI, not an FM value. The online simultaneous AMS 13C/12C measurement that allows for correction of all isotopic fractionation, including manufacture, graphitization and machine induced fractionation, is the key for obtaining consistent 14C measurements on this standard. Without further homogenization, CSC may not be a good choice of standard for an AMS that does not have the capability of measuring online AMS ?13C. Further study is needed to see if mixing/grinding can reduce the inhomogeneity. Re-measurement is suggested with more laboratories involved in order to get a better defined consensus value.

Advanced birefringence measurements in standard terahertz time-domain spectroscopy.  

PubMed

Polarization-sensitive (PS) terahertz (THz) technology can be used for investigating anisotropic materials that are opaque for visible light. A full characterization of an anisotropic material requires the extraction of the birefringence as well as the orientation of the optical axis from the measurement data. We present an approach based on THz time-domain spectroscopy (TDS) that exploits the spectral content of the THz signal for determining these two parameters from only two measurements. In contrast to an earlier approach with a more sophisticated PS-THz system and quasi-circularly polarized THz radiation, now a simple standard THz-TDS system can be employed. After a description of the mathematical model for data analysis we demonstrate the applicability of our method for a lithium niobate crystal and furthermore for a glass-fiber reinforced polymer sample, for which the orientation of the optical axis and birefringence are obtained in a spatially resolved way, showing the potential of the method also for PS-THz imaging. As no specialized setup or components are required, our approach can be easily and extensively applied for the analysis of anisotropic samples at THz frequencies. PMID:24922202

Dual-wavelength transfer standard for laser peak-power measurement  

NASA Astrophysics Data System (ADS)

The National Institute of Standards and Technology (NIST) and the Naval Surface Warfare Center - Corona Division (NSWC) have jointly developed a dual-wavelength extended-sensitivity radiometer (D-ESR) that functions as a portable transfer standard for measuring laser pulses at wavelengths of 1.06 ?m and 1.55 ?m. The peak-power irradiance range is from 500 pW/cm2 to 50 ?W/cm2 within the wavelength range of 1.54 ?m to 1.58 ?m. A similar peak-power range is covered at a wavelength of 1.06 ?m. The measurement range is covered by using smaller apertures or a neutral-density filter to reach the highest peak powers. The D-ESR radiometer is based on an InGaAs avalanche photodiode (APD) detector that is integrated with a transimpedance preamplifier module. The light-collecting optical system has a maximum aperture of approximately 125 cm2. The D-ESR is able to measure Gaussian pulse duration from 4 ns to 400 ns. The output is a negative-going pulse waveform that is measured with an oscilloscope. The total expanded uncertainty of a calibrated peak-power measurement with a D-ESR radiometer is approximately 9 % (k=2).

Pan-Canadian REspiratory STandards INitiative for Electronic Health Records (PRESTINE): 2011 National Forum Proceedings  

PubMed Central

In a novel knowledge translation initiative, the Government of Ontario’s Asthma Plan of Action funded the development of an Asthma Care Map to enable adherence with the Canadian Asthma Consensus Guidelines developed under the auspices of the Canadian Thoracic Society (CTS). Following its successful evaluation within the Primary Care Asthma Pilot Project, respiratory clinicians from the Asthma Research Unit, Queen’s University (Kingston, Ontario) are leading an initiative to incorporate standardized Asthma Care Map data elements into electronic health records in primary care in Ontario. Acknowledging that the issue of data standards affects all respiratory conditions, and all provinces and territories, the Government of Ontario approached the CTS Respiratory Guidelines Committee. At its meeting in September 2010, the CTS Respiratory Guidelines Committee agreed that developing and standardizing respiratory data elements for electronic health records are strategically important. In follow-up to that commitment, representatives from the CTS, the Lung Association, the Government of Ontario, the National Lung Health Framework and Canada Health Infoway came together to form a planning committee. The planning committee proposed a phased approach to inform stakeholders about the issue, and engage them in the development, implementation and evaluation of a standardized dataset. An environmental scan was completed in July 2011, which identified data definitions and standards currently available for clinical variables that are likely to be included in electronic medical records in primary care for diagnosis, management and patient education related to asthma and COPD. The scan, sponsored by the Government of Ontario, includes compliance with clinical nomenclatures such as SNOMED-CT® and LOINC®. To help launch and create momentum for this initiative, a national forum was convened on October 2 and 3, 2011, in Toronto, Ontario. The forum was designed to bring together key stakeholders across the spectrum of respiratory care, including clinicians, researchers, health informaticists and administrators to explore and recommend a potential scope, approach and governance structure for this important project. The Pan-Canadian REspiratory STandards INitiative for Electronic Health Records (PRESTINE) goal is to recommend respiratory data elements and standards for use in electronic medical records across Canada that meet the needs of providers, administrators, researchers and policy makers to facilitate evidence-based clinical care, monitoring, surveillance, benchmarking and policy development. The focus initially is expected to include asthma, chronic obstructive pulmonary disease and pulmonary function standards elements that are applicable to many respiratory conditions. The present article summarizes the process and findings of the forum deliberations.

We report on bulk optical refrigeration of Yb:YLF crystal to a temperature of ~124 K, starting from the ambient. This is achieved by pumping the E4-E5 Stark multiplet transition at ~1020 nm. A lower temperature of 119±1 K (~-154C) with available cooling power of 18 mW is attained when the temperature of the surrounding crystal is reduced to 210 K. This result is within only a few degrees of the minimum achievable temperature of our crystal and signifies the bulk solid-state laser cooling below the National Institute of Standards and Technology (NIST)-defined cryogenic temperature of 123 K.

Developing glovebox robotics to meet the national robot safety standard and nuclear safety criteria  

SciTech Connect

Development of a glove box based robotic system by the Lawrence Livermore National Laboratory (LLNL) is reported. Safety issues addressed include planning to meet the special constraints of operations within a hazardous material glove box and with hostile environments, compliance with the current and draft national robotic system safety standards, and eventual satisfaction of nuclear material handling requirements. Special attention has been required for the revision to the robot and control system models which antedate adoption of the present national safety standard. A robotic test bed, using non-radioactive surrogates is being activated at the Lawrence Livermore National Laboratory to develop the material handling system and the process interfaces for future special nuclear material processing applications. Part of this effort is to define, test, and revise adequate safety controls to ensure success when the system is eventually deployed at a DOE site. The current system is primarily for demonstration and testing, but will evolve into the baseline configuration from which the production system is to be derived. This results in special hazards associated with research activities which may not be present on a production line. Nuclear safety is of paramount importance and has been successfully addressed for 50 years in the DOE weapons production complex. It carries its particular requirements for robot systems and manual operations, as summarized below: Criticality must be avoided (materials cannot consolidate or accumulate to approach a critical mass). Radioactive materials must be confined. The public and workers must be protected from accountable radiation exposure. Nuclear material must be readily retrievable. Nuclear safety must be conclusively demonstrated through hazards analysis. 7 refs.

Nanosatellite standardization and modularization as an asset to space weather measurements  

NASA Astrophysics Data System (ADS)

The continuity of measurements from satellites in the Magnetosphere and Ionosphere is essential for the space weather community as pointed out by the US National Space Weather Program. Challenges to space budgets and the growing dependence upon space weather prediction have opened the door for extremely small satellites to play a large role in making these measurements. Standardization allows for modularity and the ability to lower satellite cost by reusing instrumentation and satellite systems without redesigning interfaces. Use of nanosatellites gives a designer the freedom to depart from the customary larger satellite design by deploying standardized interfaces throughout the spacecraft bus. Examples from the Boston University Student Satellite for Application and Training (BUSAT), the Thunderstorms and Effects Scientific and Technology nanosatellite (TEST), and the Loss Cone Imaging Instrument (LCI) will be provided. BUSAT is a five instrument nanosatellite with a nine pixel Imaging Electron Spectrometer, a Magnetometer, an Auroral Imager, a Very Low Frequency receiver, and a Langmuir Plasma Probe. Its purpose is to further the understanding of the coupling between energetic particles originating in the magnetosphere and their subsequent effects on the Ionosphere. In addition to their space weather science objective, BUSAT’s subsystems are based on the Cubesat concept and have been standardized, enabling them to be stacked in any orientation. Subsystems are not limited in size to the basic 1U cube, but are able to be any multiple of that size in any direction.

Lawrence Livermore National Laboratory Site Specific Standard for Nonnuclear Safety Analysis  

SciTech Connect

Lawrence Livermore National Laboratory (LLNL) and the NNSA Livermore Site Office teamed up to prepare a site specific work smart standard setting requirements for preparation of safety basis documents for LLNL non-nuclear operations and facilities. This standard documents how all hazards (biological, chemical, explosive, industrial, and radiological) shall be evaluated, classified, analyzed, and controls developed. This standard was developed to evaluate hazards at the facility level to mesh with LLNL's ISM system for reviewing hazards at the activity level. This standard presents an approach to establishing safety basis for non-nuclear operations and activities, taking a graded approach based on the potential for impacts to the health of collocated workers and the public. Direct worker safety is covered by LLNL's work activity level reviews and requirements. This standard includes streamlined mechanisms for classifying hazards based upon the unmitigated potential for human health impacts. A review or practices at several private industries, government laboratories, and DOE complex sites provided a benchmark and comparison of safety analysis processes. These approaches were compared with LLNL's existing systems, leading to a determination that facility specific safety basis documents added value to a rapid authorization for new work activities in LLNL facilities. A process for hazard classification that would be viewed as more credible than the previous facility classification system was developed, including a method allowing correlation of chemical inventories with TEEL* concentrations. A graded approach for classification of explosive hazards, consistent with the DOE Explosive Safety Manual, was included. The standard was designed to be complementary with LLNL's existing work smart standards covering the hazards identified in a facility. A standard for LLNL's Work Smart Standard set was prepared that will assure all hazards are covered with appropriate levels of analysis to provide a safety basis for non-nuclear facilities and operations. Other sites may find the overall approach a credible mechanism with a graded approach to classification and hazard and accident analysis to provide a safety basis for non-nuclear facilities and operations.

Standard audiograms for the IEC 60118-15 measurement procedure.  

PubMed

For the characterization of hearing aids, a new test method has been defined in the new International Electrotechnical Commission (IEC) standard 60118-15. For this characterization, the hearing aid will be set to actual user settings as programmed by standard fitting software from the hearing aid manufacturer. To limit the variation of programming outcomes, 10 standard audiograms, which cover the entire range of audiograms met in clinical practice, have been defined. This article describes how the set of standard audiograms has been developed. This set of standard audiogram has been derived by a vector quantization analysis method on a database of 28,244 audiograms. Using this analysis method, sets of typical audiograms have been obtained of sizes 12 and 60. It turned out that the smaller set could not be used for selecting audiograms as sloping audiograms were absent. Therefore, the larger set has been analyzed to provide seven standard audiograms for flat and moderately sloping hearing loss and three standard audiograms for steep hearing loss. PMID:20724358

Execution time, kinetics, and kinematics of the mae-geri kick: comparison of national and international standard karate athletes.  

PubMed

Little is known of the performance characteristics of the shotokan karate mae-geri kick. The aim of this study was to compare the execution time, the lower limb kinetics and kinematics, and their respective repeatability in the mae-geri kick of karate athletes of two different standards. Seventeen adult black belt karate competitors (9 national and 8 international athletes) performed six kicks with their dominant lower limb on a striking surface, combining maximum force impact and velocity. Execution time of movement and lower limb kinematics were recorded with a high-speed camera. Maximum force at impact and the forces exerted on the ground were measured using three force plates. The duration of the kick was significantly shorter for international than for national standard athletes. However, no significant difference in the maximum impact force of the kick was observed between the two groups. In addition, significant kinematic differences were observed between the groups, with two angles of motion and one velocity peak occurring sooner in the kick movement for the international athletes, specifically for the knee joint. International athletes also performed the kick with a significantly higher repeatability for duration and kinematics, specifically during the pre-loading phase that precedes the attack phase. We conclude that the duration of the kick and repeatability of lower limb kinematics could be useful in selecting top-level karate athletes and monitoring their training status. PMID:21995835

Middle school students' understanding of time: Implications for the National Science Education Standards  

NASA Astrophysics Data System (ADS)

Measures of time are essential to human life, especially in the Western world. Human understanding of time develops from the preschool stages of using "before" and "after" to an adult understanding and appreciation of time. Previous researchers (for example, Piaget, Friedman) have investigated and described stages of time development. Time, as it was investigated here, can be classified as conventional, logical or experiential. Conventional time is the ordered representation of time; the days of the week, the months of the year, or clock time: seconds and hours. Logical time is the deduction of duration based on regular events; for example, calculating the passage of time based on two separate events. Experiential time involves the duration of events and estimating intervals. With the recent production of the National Science Education Standards (NSES), many schools are aligning their science curriculum with the NSES. Time appears both implicitly and explicitly in the NSES. Do Middle School students possess the understanding of time necessary to meet the recommendations of the NSES? An interview protocol of four sessions was developed to investigate middle school students understanding of time. The four sessions included: building and testing water clocks; an interview about water clocks and time intervals; a laserdisc presentation about relative time spans; and a mind mapping session. Students were also given the GALT test of Logical Thinking. The subjects of the study were interviewed; eleven eighth grade students and thirteen sixth grade students. The data was transcribed and coded, and a rubric was developed to evaluate students based on their responses to the four sessions. The Time Analysis Rubric is a grid of the types of time: conventional, logical and experiential time versus the degree of understanding of time. Student results were assigned to levels of understanding based on the Time Analysis Rubric. There was a relationship (although not significant) between the students' GALT score and the Time Analysis Rubric results. There was no difference in Time Analysis levels between sixth and eighth grade students. On the basis of this study, Middle School students' level of understanding of time appears to be sufficient to master the requirements of the NSES.

Standards for testing freeform measurement capability of optical and tactile coordinate measuring machines  

NASA Astrophysics Data System (ADS)

For decades three-dimensional (3D) measurements of engineering components have been made using fixed metrology-room based coordinate measuring machines (CMMs) fitted most commonly with single point or to a much lesser extent, scanning tactile probes. Over the past decade there has been a rapid uptake in development and subsequent use of portable optical-based 3D coordinate measuring systems. These optical-based systems capture vast quantities of point data in a very short time, often permitting freeform surfaces to be digitized. Documented standards, for example ISO 10360, for the verification of fixed CMMs fitted with tactile probes are now widely available, whereas verification procedures and more specifically verification artefacts for optical-based systems are still in their infancy. Furthermore, the industry is seeking traceability in 3D measurements of high precision components. A recent requirement is the demand for highly accurate measurements of large gears with diameters up to 1000 mm as used in gear boxes of wind turbines. Up until now it has been impossible to ensure traceability of 3D measurements of big gears, since no traceable standards were available. This paper describes three different types of artefacts that were developed during the project, namely tetrahedron artefacts for testing the basic measurement capability of optical 3D devices, freeform verification artefacts for testing the capability of measuring complex geometry, and a large gear artefact for task related calibration of different types of CMMs. In addition, artefact calibration data and associated measurement uncertainties and international intercomparisons are presented. These developments will be of considerable value to end users, calibration laboratories and producers of optical and tactile CMMs.

Federal standards and procedures for the National Watershed Boundary Dataset (WBD)  

USGS Publications Warehouse

The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. This document establishes interagency guidelines, standards, and procedures for creating the WBD as seamless and hierarchical hydrologic unit data, based on topographic and hydrologic features at a 1:24,000 scale in the United States, except for Alaska at 1:63,360 scale, and 1:25,000 scale in the Caribbean. The data within the WBD are reviewed for certification through the 12-digit hydrologic unit against compliance to the criteria outlined in this document. Although not required as part of the framework WBD, the guidelines contain details for compiling and delineating the boundaries of two additional levels, the 14- and 16-digit hydrologic units, as well as the use of higher resolution base information to improve delineations. The guidelines presented herein are designed to enable local, regional, and national partners to consistently and accurately delineate hydrologic units. Such consistency improves watershed management through efficient sharing of information and resources and by ensuring that digital geographic data are usable with other related Geographic Information System (GIS) data. Terminology, definitions, and procedural information are provided to ensure uniformity in hydrologic unit boundaries, names, and numerical codes. Detailed standards and specifications for data are included. The document also includes discussion of objectives, communications required for revising the data resolution in the United States and the Caribbean, as well as final review and data-quality criteria. Instances of unusual landforms or artificial features that affect the hydrologic units are described with metadata standards. Up-to-date information and availability of the hydrologic units are listed at http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/.

A standards-based formative evaluation of a national professional development program for science teachers  

NASA Astrophysics Data System (ADS)

The 1996 National Science Education Standards provided educators and policy makers with a major impetus for constructive change in science education. The Standards not only specified what science content should be taught, but also provided organization for future science curricula. A major theme that pervades the Standards is that the classroom teacher is the most important component of classroom change and that reform efforts should be directed at improving the teaching of science through professional development for science teachers. In response to the National Science Education Standards, the Science Teachers Organization (pseudonym) prepared a professional development program for science teachers that was intended to acquaint teachers with the Standards and bring about reform of science teaching by changing teachers' instructional strategies and procedures. This program, named Preparing Schools for Science (PSS), was designed for use in all of the 50 states, but was first introduced in a southwestern state referred to as Utopia in this dissertation. Using the Provus Method of Discrepancy Evaluation, a design and installation audit of the Preparing Schools for Science Program was performed. Suggestions for program improvement, as well as a complete evaluation design for the PSS Program, were presented. Specific program modifications suggested by the research included an improved organization of personnel to monitor and supervise the program, more sustained professional development workshops, a stronger network of support for teachers. Five major implications for future professional development programs emerge from this research. (1) A needs analysis should be conducted before a program is designed in order to ensure that the program meet the needs of those for whom it is intended. (2) The length and type of training are the most important factors in ensuring that teachers have sufficient time to incorporate and learn how to use new ideas. (3) Additional personnel are needed to conduct the training and follow-up with the Points of Contact (POCs) in the Program. (4) Financial support for the Key Leaders who serve as trainers of the points of contact is needed to provide the means for the key leaders to fully implement the program and maintain contact with the POCs. (5) The program should have a thorough and well-planned evaluation design, and data collection should be done in a timely fashion by a skilled evaluator.

Integrating Susceptibility into Environmental Policy: An Analysis of the National Ambient Air Quality Standard for Lead  

PubMed Central

Susceptibility to chemical toxins has not been adequately addressed in risk assessment methodologies. As a result, environmental policies may fail to meet their fundamental goal of protecting the public from harm. This study examines how characterization of risk may change when susceptibility is explicitly considered in policy development; in particular we examine the process used by the U.S. Environmental Protection Agency (EPA) to set a National Ambient Air Quality Standard (NAAQS) for lead. To determine a NAAQS, EPA estimated air lead-related decreases in child neurocognitive function through a combination of multiple data elements including concentration-response (CR) functions. In this article, we present alternative scenarios for determining a lead NAAQS using CR functions developed in populations more susceptible to lead toxicity due to socioeconomic disadvantage. The use of CR functions developed in susceptible groups resulted in cognitive decrements greater than original EPA estimates. EPA’s analysis suggested that a standard level of 0.15 µg/m3 would fulfill decision criteria, but by incorporating susceptibility we found that options for the standard could reasonably be extended to lower levels. The use of data developed in susceptible populations would result in the selection of a more protective NAAQS under the same decision framework applied by EPA. Results are used to frame discussion regarding why cumulative risk assessment methodologies are needed to help inform policy development.

ISO 20462: a psychophysical image quality measurement standard  

NASA Astrophysics Data System (ADS)

ISO 20462, a three-part standard entitled "Psychophysical experimental methods to estimate image quality," is being developed by WG18 (Electronic Still Picture Imaging) of TC42 (Photography). As of late 2003, all three parts were in the Draft International Standard (DIS) ballot stage, with publication likely during 2004. This standard describes two novel perceptual methods, the triplet comparison technique and the quality ruler, that yield results calibrated in just noticeable differences (JNDs). Part 1, "Overview of psychophysical elements," discusses specifications regarding observers, test stimuli, instructions, viewing conditions, data analysis, and reporting of results. Part 2, "Triplet comparison method," describes a technique involving simultaneous five-point scaling of sets of three stimuli at a time, arranged so that all possible pairs of stimuli are compared exactly once. Part 3, "Quality ruler method," describes a real-time technique optimized for obtaining assessments over a wider range of image quality. A single ruler is a series of ordered reference stimuli depicting a common scene but differing in a single perceptual attribute. Methods for generating quality ruler stimuli of known JND separation through modulation transfer function (MTF) variation are provided. Part 3 also defines a unique absolute Standard Quality Scale (SQS) of quality with one unit equal to one JND. Standard Reference Stimuli (SRS) prints calibrated against this new scale will be made available through the International Imaging Industry Association.

What should DOE do to help establish voluntary consensus standards for measuring and rating the performance of PV modules?  

NASA Technical Reports Server (NTRS)

In response to concern expressed by the photovoltaics community over progress toward the establishment and issuance of concensus standards on photovoltaic performance measurements, a review of the status of and progress in developing these standards was conducted. It examined the roles of manufacturers, and consumers and the national laboratories funded by the U.S. Department of Energy (DOE) in supporting this effort. This was done by means of a series of discussions with knowledgeable members of the photovoltaic community. Results of these interviews are summarized and a new approach to managing support of standards activity is recommended that responds to specific problems found in the performance measurement standards area. The study concludes that there is a positive role to be played by the U.S. Department of Energy in establishing collector performance measurement standards. It recommends that DOE continue to provide direct financial support for selected committees and for research at national laboratories, and that management of the activity be restructured to increase the authority and responsibility of the consensus committees.

A collaborative study to establish the first National Standard for HIV-1 RNA nucleic acid amplification techniques (NAT) in Taiwan.  

PubMed

The World Health Organization (WHO) International Standard (IS) for human immunodeficiency virus type 1 (HIV-1) RNA is only available in limited amounts. It is critical to use the most common HIV-1 genotype as source for secondary standards, e.g. a National Standard for Taiwan. The objective of this study was to establish the first National Standard for HIV-1 RNA NAT assays in Taiwan. A collaborative study, including eleven laboratories from five different countries, was carried out to establish the HIV-1 RNA National Standard by calibration, in International Units (IU), against the WHO HIV-1 RNA IS. The HIV-1 RNA content for the candidate was quantitated by each laboratory in three independent assays and the results were collected and analyzed statistically. Overall, a high level of agreement among results was achieved from different laboratories. In addition, the stability study indicated that the candidate was stable for 24 months at -80±5°C. In conclusion, the candidate standard was established as the first National Standard for HIV-1 RNA for use in NAT assays in Taiwan. The standard is intended to be used for the quality control of HIV-1 NAT assays and as a quantitative reference material for HIV-1 NAT assays. PMID:23608407

Improving the Nation's Climate Literacy through the Next Generation Science Standards  

NASA Astrophysics Data System (ADS)

Climate Literacy: The Essential Principles of Climate Science (2009) presented the information that is deemed important for individuals and communities to know and understand about Earth's climate, impacts of climate change, and approaches to adaptation or mitigation by a group of federal agencies, science and educational partners. These principles guided the development of the NRC Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012) and the Next Generation Science Standards (NGSS, 2013). National Science Foundation recently funded two partnership projects which support the implementation of the climate component of the NGSS using the Climate Literacy framework. The first project, the Climate Literacy and Energy Awareness Network (CLEAN), was launched in 2010 as a National Science Digital Library (NSDL) Pathways project. CLEAN's primary effort is to steward a collection of educational resources around energy and climate topics and foster a community that supports learning about climate and energy topics. CLEAN's focus has been to integrate the effective use of the educational resources across all grade levels - with a particular focus on the middle-school through undergraduate levels (grades 6-16) and align the resources with educational standards. The second project, the Maryland and Delaware Climate Change Education, Assessment and Research (MADE-CLEAR) program is supported by a Phase II Climate Change Education Partnership (CCEP) grant awarded to the University System of Maryland (USM) by the National Science Foundation. The MADE-CLEAR project's related goals are to support innovations in interdisciplinary P-20 (preschool through graduate school) climate change education, and develop new pathways for teacher education and professional development leading to expertise in climate change content and pedagogy. Work in Maryland, Delaware (MADE-CLEAR) and other states on the implementation of the NGSS, that will utilize the years of work, the efforts of hundreds of community members and tens of millions of dollars of investment and to increase the nations climate literacy, will be highlighted. We will particularly focus on the partnerships among MADE-CLEAR, NOAA and CLEAN. Climate science and energy are complex topics, with rapidly developing science and technology and the potential for controversy. The NGSS offer educators an opportunity to effectively bring these important subjects into their classrooms across a learning progression spanning K-12 and well beyond. Yet regardless of the pedagogic setting, using a literacy-based approach can provide a sound foundation for building learners' understanding of these topics. In this presentation, we will describe contributions by a group of collaborative projects and organizations to support the NGSS implementation through an integrated Earth system science approach in K-12 education.

Comparison of methods for estimating Wet-Bulb Globe Temperature index from standard meteorological measurements.  

PubMed

Environmental heat illness and injuries are a serious concern for the Army and Marines. Currently, the Wet-Bulb Globe Temperature (WBGT) index is used to evaluate heat injury risk. The index is a weighted average of dry-bulb temperature (Tdb), black globe temperature (Tbg), and natural wet-bulb temperature (Tnwb). The WBGT index would be more widely used if it could be determined using standard weather instruments. This study compares models developed by Liljegren at Argonne National Laboratory and by Matthew at the U.S. Army Institute of Environmental Medicine that calculate WBGT using standard meteorological measurements. Both models use air temperature (Ta), relative humidity, wind speed, and global solar radiation (RG) to calculate Tnwb and Tbg. The WBGT and meteorological data used for model validation were collected at Griffin, Georgia and Yuma Proving Ground (YPG), Arizona. Liljegren (YPG: R(2) = 0.709, p < 0.01; Griffin: R(2) = 0.854, p < 0.01) showed closer agreement between calculated and actual WBGT than Matthew (YPG: R(2) = 0.630, p < 0.01; Griffin: R(2) = 0.677, p < 0.01). Compared to actual WBGT heat categorization, the Matthew model tended to underpredict compared to Liljegren's classification. Results indicate Liljegren is an acceptable alternative to direct WBGT measurement, but verification under other environmental conditions is needed. PMID:23929057

Does the HON apply to your facility. [Hazardous Organic National emission standards  

SciTech Connect

Operators must use new guidelines to determine if their hydrocarbon processing industry (HPI) facility is regulated by the Hazardous Organic NESHAP (National Emissions Standards for Hazardous Air Pollutants). Also known as the HON, this recently promulgated rule regulates 385 different chemicals and 112 air pollutants. Targeting decentralized emission sources such as process vents, storage vessels, transfer operations, wastewater streams and equipment leaks, this rule is a complex definition and application problem. If the refining complex produces or uses listed chemicals or hazardous air pollutants (HAPs) within any process, the rule applies. Result: The facility must meet notification dates to the regulating agencies, identify major sources and develop emission control strategies to bring the source into compliance. These guidelines show how to develop a cost-effective control strategy and examine the pitfalls from improper emission averaging.

Projected compliance with the PM2.5 National Ambient Air Quality Standards. Final report  

SciTech Connect

In 1997, the State of Maryland had no available ambient Federal Reference Method data on particulate matter less than 2.5 microns in aerodynamic diameter (PM2.5) but did have annual ambient data for particulate matter smaller than 10 microns (PM10) at twenty-four sites. The PM10 data was analyzed in conjunction with local annual and seasonal ZIP code-level emission inventories and with speciated PM2.5 data from four nearby monitors in the IMPROVE network (located in the national parks and wilderness areas) in an effort to predict annual average and seasonal high PM2.5 concentrations at the twenty-four PM10 monitor sites operated from 1992 to 1996. All seasonal high concentrations were predicted to be below the 24-hour PM2.5 National Ambient Air Quality Standard (NAAQS) at the sites operated in Maryland between 1992 and 1996. A geographic analysis of the emission inventories was also performed to evaluate the impact of PM2.5 emissions from Maryland`s power plants on fourteen monitor locations that were predicted to have a reading exceeding the annual NAAQS for any year.

Willingness to pay and political support for a US national clean energy standard  

NASA Astrophysics Data System (ADS)

In 2010 and 2011, Republicans and Democrats proposed mandating clean power generation in the electricity sector. To evaluate public support for a national clean energy standard (NCES), we conducted a nationally representative survey that included randomized treatments on the sources of eligible power generation and programme costs. We find that the average US citizen is willing to pay US$162 per year in higher electricity bills (95% confidence interval: US$128-260), representing a 13% increase, in support of a NCES that requires 80% clean energy by 2035. Support for a NCES is lower among non-whites, older individuals and Republicans. We also employ our statistical model, along with census data for each state and Congressional district, to simulate voting behaviour on a NCES by Members of Congress assuming they vote consistently with the preferences of their median voter. We estimate that Senate passage of a NCES would require an average household cost below US$59 per year, and House passage would require costs below US$48 per year. The results imply that an `80% by 2035' NCES could pass both chambers of Congress if it increases electricity rates less than 5% on average.

Constructing uniformity: The standardization of international electromagnetic measures, 1860-1912  

SciTech Connect

Metrology gained much attention from electrical scientists and practitioners in the nineteenth and early twentieth centuries. Spurred by the expanding telegraph industries, they considered the construction and acceptance of a universal system of electromagnetic measures essential for the growth of science and technology. The task was not easy. Scientists and practitioners, having different concerns and needs, often found themselves at odds. National rivalries further obstructed the attainment of uniform measures. Under the auspices of a series of international electrical congresses and conferences between 1881 and 1908, the systembuilders succeeded in establishing an international system of practical electrical units and standards-the ohm, volt, ampere, coulomb, farad, joule, and watt-based on the centimeter-gram-second (CGS) system of measures. They had less success, however, with practical magnetic units. They had designed the system of electrical units to meet the needs of telegraphy. But the rise of the technologies of electrical power in the late nineteenth century made it difficult to define magnetic units that were both practical for the new technologies and coherent with the existing system of units. The international congress, as an institution, also gave them trouble. It lacked authority and stability and, in some cases, hindered the development of the system of units. More credit for the success of the systembuilders must go, paradoxically, to the national physical laboratoires that arose in Germany, France, Great Britain, and the United States circa 1900. They enabled the standarization of international electromagnetic measures by narrowing the community of systembuilders to a small circle of elite experts. This historical process illustrates important aspects of the ways and means of standarization, of the technical and social construction of uniformity.

Development and verification of air balance gas primary standards for the measurement of nitrous oxide at atmospheric levels.  

PubMed

The Gas Metrology Group at the National Institute of Standards and Technology (NIST) became active in developing primary standards at ambient levels of N2O in the 1980s, and this has continued through to the present. In recent years, interest in NIST-traceable standards has increased-not only at the ambient level of approximately 325 nmol mol(-1) (ppb) but at micromole per mole (ppm) levels as well. In order to support two in-process dry whole air standard reference materials (SRMs 1720 and 1721) and the NIST Traceable Reference Materials (NTRM) program, a project was implemented in the Gas Metrology Group to produce a complete suite of new primary standard materials (PSMs) of N2O with synthetic air (O2/N2) as the balance gas. Six levels of dilution, approximately 1 order of magnitude apart, were gravimetrically prepared and verified. Each level serves as the "parent mix" for the next level. This discussion describes the process of producing each level and then verifying its amount-of-substance fraction. Expanded uncertainties, k = 2, of 0.025% relative to the gravimetric amount-of-substance fraction were obtained at the ambient level. One standard from the final group of standards at the ambient amount-of-substance fraction level was compared with standards from the National Oceanographic and Atmospheric Administration and the Scripps Institution of Oceanography, two organizations experienced in gas standards preparation and ambient whole air measurements, and shows agreement to 0.07 nmol mol(-1) (0.02% relative) and 0.20 nmol mol(-1) (0.06% relative), respectively.

Using quasars as standard clocks for measuring cosmological redshift.  

PubMed

We report hitherto unnoticed patterns in quasar light curves. We characterize segments of the quasar's light curves with the slopes of the straight lines fit through them. These slopes appear to be directly related to the quasars' redshifts. Alternatively, using only global shifts in time and flux, we are able to find significant overlaps between the light curves of different pairs of quasars by fitting the ratio of their redshifts. We are then able to reliably determine the redshift of one quasar from another. This implies that one can use quasars as standard clocks, as we explicitly demonstrate by constructing two independent methods of finding the redshift of a quasar from its light curve. PMID:23003944

Modern topics in standardized laser-induced damage threshold measurements  

Microsoft Academic Search

Although the measurement of the laser-induced damage threshold is a field of permanent research effort since the late 1960s, the optimization of the damage handling capability is still a key issue for the development of high performance laser systems. In conjunction with the ever increasing demand for lasers with high average power, energy, extreme wavelengths or short pulses, the resistance

Standardization of surface potential measurements of graphene domains  

PubMed Central

We compare the three most commonly used scanning probe techniques to obtain a reliable value of the work function in graphene domains of different thickness. The surface potential (SP) of graphene is directly measured in Hall bar geometry via a combination of electrical functional microscopy and spectroscopy techniques, which enables calibrated work function measurements of graphene domains in ambient conditions with values ?1LG ~4.55 ± 0.02?eV and ?2LG ~ 4.44 ± 0.02?eV for single- and bi-layer, respectively. We demonstrate that frequency-modulated Kelvin probe force microscopy (FM-KPFM) provides more accurate measurement of the SP than amplitude-modulated (AM)-KPFM. The discrepancy between experimental results obtained by different techniques is discussed. In addition, we use FM-KPFM for contactless measurements of the specific components of the device resistance. We show a strong non-Ohmic behavior of the electrode-graphene contact resistance and extract the graphene channel resistivity.

ASTM standards for measuring solar reflectance and infrared emittance of construction materials and comparing their steady-state surface temperatures  

SciTech Connect

Numerous experiments on individual buildings in California and Florida show that painting roofs white reduces air conditioning load up to 50%, depending on the thermal resistance or amount of insulation under the roof. The savings, of course, are strong functions of the thermal integrity of a building and climate. In earlier work, the authors have estimated the national energy savings potential from reflective roofs and paved surfaces. Achieving this potential, however, is conditional on receiving the necessary Federal, states, and electric utilities support to develop materials with high solar reflectance and design effective implementation programs. An important step in initiating an effective program in this area is to work with the american Society for Testing and Materials (ASTM) and the industry to create test procedures, rating, and labeling for building and paving materials. A subcommittee of ASTM E06, E06.42, on Cool Construction Materials, was formed as the vehicle to develop standard practices for measuring, rating, and labeling cool construction materials. The subcommittee has also undertaken the development of a standard practice for calculating a solar reflectance index (SRI) of horizontal and low-sloped surfaces. SRI is a measure of the relative steady-state temperature of a surface with respect to a standard white surface (SRI = 100) and a standard black surface (SRI = 0) under standard solar and ambient conditions. This paper discusses the technical issues relating to development of these two ASTM standards.

Clinical transfusion practice update: haemovigilance, complications, patient blood management and national standards.  

PubMed

Blood transfusion is not without risk. Although the risks of HIV and hepatitis transmission have diminished, haemovigilance programs highlight that other significant transfusion hazards remain. Sepsis from bacterial contamination is the most common residual infectious hazard in developed countries, and events due to clerical error are problematic. Unnecessary transfusions should be avoided. New national guidelines on patient blood management (PBM) emphasise holistic approaches, including strategies to reduce transfusion requirements. Perioperative PBM should incorporate preoperative haemoglobin and medication optimisation, intraoperative blood conservation, and consideration of restrictive postoperative transfusion and cell-salvage techniques. When massive transfusion is required, hospitals should implement massive transfusion protocols. These protocols reduce mortality, improve communication and facilitate adequate provision of blood products. They should include multidisciplinary team involvement and guidelines for use of blood components and adjunctive agents. Although fresh frozen plasma to red blood cell and platelet to red blood cell ratios of ? 1 : 2 appear to reduce mortality in trauma patients who receive massive transfusion, there is insufficient evidence to recommend specific ratios. Systematic reviews have found no significant benefit of recombinant activated factor VII in critical bleeding, and an increase in thromboembolic events; specialist haematology advice is therefore recommended when considering use of this agent. The National Safety and Quality Health Service Standards address use of blood and blood products, and provide important transfusion principles for adoption by all clinicians. Storage of red cells in additive solution results in changes, known as the "storage lesion", and studies to determine the clinical effect of the age of blood at transfusion are ongoing.
