The Waste Characterization Plan for the Waste Sampling and Characterization Facility (WSCF) complex describes the organization and methodology for characterization of all waste streams that are transferred from the WSCF Laboratory Complex to the Hanford Site 200 Areas Storage and Disposal Facilities. Waste generated at the WSCF complex typically originates from analytical or radiological procedures. Process knowledge is derived from these operations and should be considered an accurate description of WSCF generated waste. Sample contribution is accounted for in the laboratory waste designation process and unused or excess samples are returned to the originator for disposal. The report describes procedures and processes common to all waste streams; individual waste streams; and radionuclide characterization methodology.

Waste sampling and characterization facility (WSCF)  

SciTech Connect

The Waste Sampling and Characterization Facility (WSCF) complex consists of the main structure (WSCF) and four support structures located in the 600 Area of the Hanford site east of the 200 West area and south of the Hanford Meterology Station. WSCF is to be used for low level sample analysis, less than 2 mRem. The Laboratory features state-of-the-art analytical and low level radiological counting equipment for gaseous, soil, and liquid sample analysis. In particular, this facility is to be used to perform Resource Conservation and Recovery Act (RCRA) of 1976 and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 sample analysis in accordance with U.S. Environmental Protection Agency Protocols, room air and stack monitoring sample analysis, waste water treatment process support, and contractor laboratory quality assurance checks. The samples to be analyzed contain very low concentrations of radioisotopes. The main reason that WSCF is considered a Nuclear Facility is due to the storage of samples at the facility. This maintenance Implementation Plan has been developed for maintenace functions associate with the WSCF.

Bioavailability of a potato chromium complex to the laboratory rat  

SciTech Connect

Research objectives were to study the effect of food source, preparation method and chemical form on bioavailability of chromium. Chromium concentration in potatoes was determined and tubers labeled either intrinsically or extrinsically with radioactive chromate. A labeled chromium complexes was isolated from preparations of raw, baked or fried potatoes and chromatographed on gel permeation media. Availability of the potato chromium complex to the rat was examined in three feeding studies. Animals were dosed with radioactive extrinsically or intrinsically labeled potato extract or with chromate. A labeled chromium complex was isolated from gastrointestinal contents of rats and chromatographed. Potato pulp and peel contained 1.63 and 2.70 ..mu..g Cr/g tissue respectively. True and apparent absorption from extrinsically labeled feedings were 33.4 +/- 4.7 and 29.8 +/- 11.2% respectively, and no differences existed between absorption from raw and cooked potatoes. Absorption from the extrinsic labeled potatoes differed significantly from absorption of inorganic chromatium. Apparent absorption of raw (11.1 +/- 7.9%) and cooked (-0.7 +/- 2.8%) intrinsically labeled feedings differed significantly. Absorption of inorganic chromium was 17.8% (true) and 11.5% (apparent). Examination of the chromium complex isolated from gastrointestinal tract contents showed enlargement of the complex in the stomach after consumption.

Complex organics in laboratory simulations of interstellar/cometary ices.  

PubMed

We present the photochemical and thermal evolution of both non-polar and polar ices representative of interstellar and pre-cometary grains. Ultraviolet photolysis of the non-polar ices comprised of O2, N2, and CO produces CO2, N2O, O3, CO3, HCO, H2CO, and possibly NO and NO2. When polar ice analogs (comprised of H2O, CH3OH, CO, and NH3) are exposed to UV radiation, simple molecules are formed including: H2, H2CO, CO2, CO, CH4, and HCO (the formyl radical). Warming produces moderately complex species such as CH3CH2OH (ethanol), HC(=O)NH2 (formamide), CH3C(=O)NH2 (acetamide), R-CN and/or R-NC (nitriles and/or isonitriles). Several of these are already known to be in the interstellar medium, and their presence indicates the importance of grain processing. Infrared spectroscopy, 1H and 13C nuclear magnetic resonance (NMR) spectroscopy, and gas chromatography-mass spectrometry demonstrate that after warming to room temperature what remains is an organic residue composed primarily of hexamethylenetetramine (HMT, C6H12N4) and other complex organics including the amides above and polyoxymethylene (POM) and its derivatives. The formation of these organic species from simple starting mixtures under conditions germane to astrochemistry may have important implications for the organic chemistry of interstellar ice grains, comets and the origins of life.

The Synthesis and Analysis of Ammine Complexes of Copper and Silver Sulfate: An Undergraduate Laboratory Project  

NASA Astrophysics Data System (ADS)

An undergraduate chemistry laboratory project involving the synthesis of [Ag(NH3)2]2SO4 and Cu(NH3)4SO4 from the simple sulfate salts is described. Characterization of the stoichiometry of the complexes is accomplished by gravimetric and volumetric analysis. Silver is precipitated as the chloride and copper is precipitated as the hydroxide and converted to the oxide before weighing. The ammonia content of each complex is determined with a back titration using dilute nitric acid and sodium hydroxide. Typical student work gives results for the stoichiometry of the complexes within 1-5% of the theoretical values. The project provides a convenient preparation of two compounds whose identity and formula will not be obvious to the student. The analytical procedures illustrate the fundamentals of gravimetric and volumetric analysis and some basic characteristics of simple coordination complexes. The analytical data allow the student to determine the identity of each product by determining its empirical formula.

Complex plasma research on ISS PKE-Nefedov, PK-3 Plus, PK-4, and impact laboratory  

NASA Astrophysics Data System (ADS)

The international research on ISS in dusty plasma (also known as complex plasma) under prolonged microgravity condition entered a new area in March 2001: The PKE-Nefedov facility (formerly called PKE 3) performed its first experiment in radio-frequency induced complex plasmas. This bilateral German-Russian research facility operated successfully in over 13 missions over 5 years until its internal resources were consumedresulting so far in over 30 peer-reviewed scientific publications. In place of PKE-Nefedov is the next generation experiment apparatus PK 3 Plus with refined and more powerful instruments and diagnostics, which had its on-orbit commissioning in January 2006. While PK 3 Plus will further investigate the radio-frequency induced plasmas for the next few years the new PK-4 research facility is under development for investigation of direct-current induced complex plasma. Because the highly successful series of stand-alone PK experiment facilities cover only a fraction of the overall complex plasma research field the IMPACT (International Multi-User Plasma, Atmospheric and Cosmic Dust Twin) Laboratory project was initiated. The IMPF/ICAPS (IMPACT) Laboratory is the logical next step to provide a home and rallying point for the worldwide growing research efforts under microgravity conditions in the fields of dusty plasma and interactions of cosmic and atmospheric particle systems.

Analysis of Flood Hazards for the Materials and Fuels Complex at the Idaho National Laboratory Site  

SciTech Connect

Researchers at Pacific Northwest National Laboratory conducted a flood hazard analysis for the Materials and Fuels Complex (MFC) site located at the Idaho National Laboratory (INL) site in southeastern Idaho. The general approach for the analysis was to determine the maximum water elevation levels associated with the design-basis flood (DBFL) and compare them to the floor elevations at critical building locations. Two DBFLs for the MFC site were developed using different precipitation inputs: probable maximum precipitation (PMP) and 10,000 year recurrence interval precipitation. Both precipitation inputs were used to drive a watershed runoff model for the surrounding upland basins and the MFC site. Outflows modeled with the Hydrologic Engineering Centers Hydrologic Modeling System were input to the Hydrologic Engineering Centers River Analysis System hydrodynamic flood routing model.

Comparison of in situ uranium KD values with a laboratory determined surface complexation model  

USGS Publications Warehouse

Reactive solute transport simulations in groundwater require a large number of parameters to describe hydrologic and chemical reaction processes. Appropriate methods for determining chemical reaction parameters required for reactive solute transport simulations are still under investigation. This work compares U(VI) distribution coefficients (i.e. KD values) measured under field conditions with KD values calculated from a surface complexation model developed in the laboratory. Field studies were conducted in an alluvial aquifer at a former U mill tailings site near the town of Naturita, CO, USA, by suspending approximately 10 g samples of Naturita aquifer background sediments (NABS) in 17-5.1-cm diameter wells for periods of 3 to 15 months. Adsorbed U(VI) on these samples was determined by extraction with a pH 9.45 NaHCO3/Na2CO3 solution. In wells where the chemical conditions in groundwater were nearly constant, adsorbed U concentrations for samples taken after 3 months of exposure to groundwater were indistinguishable from samples taken after 15 months. Measured in situ K D values calculated from the measurements of adsorbed and dissolved U(VI) ranged from 0.50 to 10.6 mL/g and the KD values decreased with increasing groundwater alkalinity, consistent with increased formation of soluble U(VI)-carbonate complexes at higher alkalinities. The in situ K D values were compared with KD values predicted from a surface complexation model (SCM) developed under laboratory conditions in a separate study. A good agreement between the predicted and measured in situ KD values was observed. The demonstration that the laboratory derived SCM can predict U(VI) adsorption in the field provides a critical independent test of a submodel used in a reactive transport model. ?? 2004 Elsevier Ltd.

TRUEX process laboratory studies with Hanford complexant concentrate waste: Part 2, Test for solvent poisoning  

SciTech Connect

The TRUEX solvent extraction process, which has undergone extensive development at Argonne National Laboratory, is being considered for use in the processing of various wastes at Hanford. The objective of such processing would be to extract (and concentrate into a small volume of TRU waste) the contained plutonium and uranium so that the bulk of the waste can be treated as low-level waste. As part of their testing and evaluation of this process with actual wastes, Westinghouse Hanford Company (WHC) has asked the Pacific Northwest Laboratory (PNL) to perform tests to determine in a preliminary way if the wastes contain some material that was not encountered in the earlier studies and that might ''poison'' the solvent in some way, thereby making TRUEX processing difficult or very expensive. This report discusses the results obtained with complexant concentrate (CC) waste. This waste contains large quantities of organic complexing agents (e.g., EDTA, HEDTA) and organic acids (e.g., citric, tartaric), and/or degradation products of these materials, that were added to the waste during an earlier processing for the removal of strontium. It was thus thought to be a waste having a higher probability than most wastes of containing material that might have deleterious effects of TRUEX processing. 1 fig., 2 tabs.

Complex apodization Lyot coronagraphy for the direct imaging of exoplanet systems: design, fabrication, and laboratory demonstration  

NASA Astrophysics Data System (ADS)

We review the design, fabrication, performance, and future prospects for a complex apodized Lyot coronagraph for highcontrast exoplanet imaging and spectroscopy. We present a newly designed circular focal plane mask with an inner working angle of 2.5 ?/D. Thickness-profiled metallic and dielectric films superimposed on a glass substrate provide control over both the real and imaginary parts of the coronagraph wavefront. Together with a deformable mirror for control of wavefront phase, the complex Lyot coronagraph potentially exceeds billion-to-one contrast over dark fields extending to within angular separations of 2.5 ?/D from the central star, over spectral bandwidths of 20% or more, and with throughput efficiencies better than 50%. Our approach is demonstrated with a linear occulting mask, for which we report our best laboratory imaging contrast achieved to date. Raw image contrasts of 310-10 over 2% bandwidths, 610-10 over 10% bandwidths, and 210-9 over 20% bandwidths are consistently achieved across high contrast fields extending from an inner working angle of 3 ?/D to a radius of 15 ?/D. Occulter performance is analyzed in light of experiments and optical models, and prospects for further progress are summarized. The science capability of the hybrid Lyot coronagraph is compared with requirements for ACCESS, a representative space coronagraph concept for the direct imaging and spectroscopy of exoplanet systems. This work has been supported by NASAs Strategic Astrophysics Technology / Technology Demonstrations for Exoplanet Missions (SAT/TDEM) program.

Stratigraphy of the unsaturated zone at the radioactive waste management complex, Idaho National Engineering Laboratory, Idaho  

USGS Publications Warehouse

A complex sequence of layered basalt flows, cinders, and sediment underlies the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory in southeastern Idaho. Wells drilled to 700 ft penetrate a sequence of 10 basalt-flow groups and 7 major sedimentary interbeds that range in age from about 100,000 to 600,000 years old. The 10 flow groups consist of 22 separate lava flows and flow-units. Each flow group is made up of from one to five petrographically similar flows that erupted from common source areas during periods of less than 200 years. Sedimentary interbeds consist of fluvial, lacustrine, and wind-blown deposits of clay, silt, sand, and gravel that accumulated during periods of volcanic inactivity ranging from thousands to hundreds of thousands of years. Flows and sediment are unsaturated to a depth of about 600 ft. Flows and sediment below a depth of 600 ft are saturated and make up the uppermost part of the Snake River Plain aquifer. The areal extent of flow groups and interbeds was determined from well cuttings, cores, geophysical logs, potassium-argon ages, and geomagnetic properties. Stratigraphical control was provided by four sequential basalt flows near the base of the unsaturated zone that have reversed geomagnetic polarity and high emission of natural gamma radiation compared to other flows. Natural gamma logs were used as a primary correlation tool. Natural-gamma emissions, which are generally uniform in related, petrographically similar flows, increase or decrease between petrographically dissimilar flows of different age and source. (USGS)

Chemical transformations of complex mixtures relevant to atmospheric processes: Laboratory and ambient studies  

NASA Astrophysics Data System (ADS)

The study of atmospheric chemistry and chemical transformations, which are relevant to conditions in the ambient atmosphere require the investigation of complex mixtures. In the atmosphere, complex mixtures (e.g. diesel emissions) are continually evolving as a result of physical and chemical transformations. This dissertation examines the transformations of modern diesel emissions (DE) in a series of experiments conducted at the European Outdoor Simulation Chamber (EUPHORE) in Valencia, Spain. Experimental design challenges are addressed, and the development of a NOx removal technology (denuder) is described with results from the application of the newly developed NOx denuder in the most recent EUPHORE campaign (2006). In addition, the data from an ambient aerosol study that examines atmospheric transformation products is presented and discussed. Atmospheric transformations of DE and associated secondary organic aerosol (SOA) production, along with chemical characterization of polar organic compounds (POC) in the EUPHORE experiments, provides a valuable insight on the tranformations of modern DE in environmentally relevant atmospheres. The greatest SOA production occurred in DE with toluene addition experiments (>40%), followed by DE with HCHO (for OH radical generation) experiments. A small amount of SOA (3%) was observed for DE in dark with N2O5 (for NO3 radical production) experiments. Distinct POC formation in light versus dark experiments suggests the role of OH initiated reactions in these chamber atmospheres. A trend of increasing concentrations of dicarboxylic acids in light versus dark experiments was observed when evaluated on a compound group basis. The production of diacids (as a compound group) demonstrates a consistent indicator for photochemical transformation in relation to studies in the ambient atmosphere. The four toluene addition experiments in this study were performed at different [tol]o/[NOx]o ratios and displayed an average SOA %yield (in relation to toluene) of 5.3+/-1.6%, which is compared to past chamber studies that evaluated the impact of [tol]o/[NO x]o on SOA production in more simplified mixtures. Characterization of nitrated polycyclic aromatic hydrocarbons (NPAH, nitroarenes), which have been shown to be mutagenic and/or carcinogenic, was performed on time-intergrated samples from the EUPHORE experiments. NPAH concentrations indicated significant formation and/or degradation was taking place. An inter-experimental comparison showed that distinct gas (2-nitronaphthalene) and particle (2-nitrofluoranthene, 4-nitropyrene) phase NPAH production resulted in light versus dark experiments, and degradation most likely due to photolysis was observed for one of the most abundant NPAH (1-nitropyrene) in the ambient atmosphere. The evaluation of dark experiments in high and low NOx conditions, revealed a significantly higher concentration of gas phase NPAH (mostly due to 1-nitronaphthalene) in high NOx experiments. Electrophilic nitration on chamber surfaces or sampling media can not be ruled out as a possible mechanism for the elevated NPAH concentrations. Chapter 5 presents results from an aerosol sampling study at the Storm Peak Laboratory (SPL) (3210 MSL, 40.45 N, 106.74 W) in the winter of 2007. The unique geographical character of SPL allows for extended observations/sampling of the free tropospheric interface. Of 84 analytes included in the GC-MS method, over 50 individual water extractable POC were present at concentrations greater than 0.1 ngm-3. Diurnal averages over the sampling period revealed a higher total concentration of POC at night, 211 ngm-3 (105-265 ngm-3), versus day, 160 ngm-3 (137-205 ngm -3), which suggests a more aged nighttime aerosol character. During a snow event (Jan. 11-13, 2007), the concentrations of daytime dicarboxylic acids, which may be considered as atmospheric transformation products, were reduced. Lower actinic flux, reduced transport distance, and ice crystal scavenging may explain this variability. Further evaluation of compound ratios (e.g. diacids to

Direct molecular detection of Mycobacterium tuberculosis complex from clinical samples - An adjunct to cultural method of laboratory diagnosis of tuberculosis  

PubMed Central

Background: Tuberculosis, a communicable disease with significant morbidity and mortality, is the leading cause of death in the world from bacterial infectious disease. Because of its public health importance, there is need for rapid and definitive method of detecting the causative organism. Several approaches have been attempted, but the molecular methods, especially Polymerase Chain Reaction assays are the most promising for rapid detection of Mycobacterium tuberculosis complex from clinical samples. Aim: This study was aimed at using Polymerase Chain Reaction for detection of Mycobacterium tuberculosis complex from clinical samples using universal sample processing methodology. Subjects and Methods: Two hundred clinical samples sent to Tuberculosis laboratories in Ibadan and Osogbo, Nigeria, were enrolled in this study. The samples were processed by universal sample processing methodology for PCR; smear microscopy was carried out on sputum samples by Ziehl Nelseen staining technique; and cultured on Middlebrook agar medium containing oleic acid albumin dextrose complex supplement after decontamination of samples. Results: Ninety six (48%) samples were detected positive for M. tuberculosis complex by polymerase chain reaction using the combination of boiling and vortexing and microscopy detected 72 (36%) samples positive for acid fast bacilli. Using culture method as gold standard, it was found that polymerase chain reaction assay was more sensitive (75.5%) and specific (94.8%) than microscopy (sensitivity of 48.5% and specificity of 85.7%) in detecting M. tuberculosis complex from clinical samples. There was significant difference in detecting M. tuberculosis from clinical samples when compared to microscopy (p<0.05). Conclusion: The study recommends that direct molecular detection of M. tuberculosis complex is sensitive and specific and polymerase chain reaction method should be used as an adjunct to other methods of laboratory diagnosis of tuberculosis.

Laboratory Class Project: Using a Cichlid Fish Display Tank to Teach Students about Complex Behavioral Systems  

PubMed Central

Laboratory activities serve several important functions in undergraduate science education. For neuroscience majors, an important and sometimes underemphasized tool is the use of behavioral observations to help inform us about the consequences of changes that are occurring on a neuronal level. To help address this concern, the following laboratory exercise is presented. The current project tested the prediction that the most dominant fish in a tank of cichlids will have gained the most benefits of its position resulting in the greatest growth and hence, become the largest fish. More specifically: (1) is there evidence that a social hierarchy exists among the fish in our tank based on the number of aggressive acts among the four largest fish; (2) if so, does the apparent rank correspond to the size of the fish as predicted by previous studies? Focal sampling and behavior sampling of aggressive acts between fish were utilized in the data collection. Collectively, the data suggest a social dominance hierarchy may be in place with the following rank order from highest to lowest: Fish A > Fish B > Fish D > Fish C. While the largest (Fish A) seems to be at the top, Fish C ended up being ranked lower than Fish D despite the fact that Fish C is larger. Overall, the project was considered a success by the instructor and students. The students offered several suggestions that could improve future versions of this type of project, in particular concerning the process of constructing a poster about the project. The implications of the data and student learning outcomes are discussed.

Preliminary observations on the impact of complex stress histories on sandstone response to salt weathering: laboratory simulations of process combinations  

NASA Astrophysics Data System (ADS)

Historic sandstone structures carry an inheritance, or a memory, of past stresses that the stone has undergone since its placement in a faade. This inheritance, which conditions present day performance, may be made up of long-term exposure to a combination of low magnitude background environmental factors (for example, salt weathering, temperature and moisture cycling) and, superimposed upon these, less frequent but potentially high magnitude events or exceptional factors (for example, lime rendering, severe frost events, fire). The impact of complex histories on the decay pathways of historic sandstone is not clearly understood, but this paper seeks to improve that understanding through the use of a laboratory process combination study. Blocks of quartz sandstone (Peakmoor, from NW England) were divided into subsets that experienced different histories (lime rendering and removal, fire and freeze-thaw cycles in isolation and combination) that reflected the event timeline of a real medieval sandstone monument in NE Ireland, Bonamargy Friary (McCabe et al. 2006b). These subsets were then subject to salt weathering cycles using a 10% salt solution of NaCl and MgSO4 that represents the every-day stress environment of, for example, sandstone structures in coastal, or polluted urban, location. Block response to salt weathering was monitored by collecting, drying and weighing the debris that was released as blocks were immersed in the salt solution at the beginning of each cycle. The results illustrate the complexity of the stone decay system, showing that seemingly small variations in stress history can produce divergent response to salt weathering cycles. Applied to real-world historic sandstone structures, this concept may help to explain the spatial and temporal variability of sandstone response to background environmental factors on a single faade, and encourage conservators to include the role of stress inheritance when selecting and implementing conservation strategies.

Addressing the complexity and diversity of agricultural plant volatiles: a call for the integration of laboratory- and field-based analyses.  

PubMed

As the sophistication and sensitivity of chemical instrumentation increase, so does the number of applications. Correspondingly, new questions and opportunities for systems previously studied also arise. As with most plants, the emission of volatiles from agricultural products is complex and varies among commodities. Volatiles are indicative of characteristics such as food quality, cultivar type, phenological stage, and biotic and abiotic stressors; thus, their systematic and accurate evaluation is important. Early volatile analyses entailed removal of the sample matrix in question, transport to the laboratory, and subsequent investigation. More recently, scientists are moving the laboratory to the field to obtain realistic emission patterns of the sample in its natural environment. This perspective proposes that a methodical and collaborative approach to the complex relationship between volatiles and agricultural commodities and their various phenological stages, oxidative degradation products, and fungal contamination is needed in order to fully comprehend the sample and associated relationships as a whole. These methodical approaches should incorporate both in situ and ex situ investigations of the sample. Ultimately, there exists an opportunity for development of methodologies that integrate both laboratory- and field-based collection of volatiles to explore and address the complex biological interactions of agricultural systems.

Programmed improvements of the alternating gradient synchrotron complex at Brookhaven National Laboratory, Upton, New York. Environmental assessment  

SciTech Connect

The purpose and need for DOE to undertake the actions described in this document are to improve the efficiency of the Alternating Gradient Synchrotron (AGS) complex. Benefits would include optimization of the AGS scientific program, increased high-energy and nuclear physics experimentation, improved health and safety conditions for workers and users, reduced impact on the environment and the general public, energy conservation, decreased generation of hazardous and radioactive wastes, and completion of actions required to permit the AGS to be the injector to the Relativistic Heavy Ion Collider (RHIC)., Improved efficiency is defined as increasing the AGS`s capabilities to capture and accelerate the proton intensity transferred to the AGS from the AGS booster. Improved capture of beam intensity would reduce the beam losses which equate to lost scientific opportunity for study and increased potential for radiation doses to workers and the general public. The action would also refurbish magnets used in the transfer tunnel which connects the AGS complex to RHIC to permit smooth injection of beam into the RHIC accelerator. These magnets were previously used to direct beam to fixed targets for high energy physics studies but have hot received proper maintenance to be reliable as injectors to RHIC. The document describes alternative actions, the affected environment, and environmental impacts.

Why Model-Based Engineering and Manufacturing Makes Sense for the Plants and Laboratories of the Nuclear Weapon Complex  

SciTech Connect

The purpose of this White Paper is to outline the benefits we expect to receive from Model-Based Engineering and Manufacturing (MBE/M) for the design, analysis, fabrication, and assembly of nuclear weapons for upcoming Life Extension Programs (LEPs). Industry experiences with model-based approaches and the NNSA/DP investments and experiences, discussed in this paper, indicate that model-based methods can achieve reliable refurbished weapons for the stockpile with less cost and time. In this the paper, we list both general and specific benefits of MBE/M for the upcoming LEPs and the metrics for determining the success of model-based approaches. We also present some outstanding issues and challenges to deploying and achieving long-term benefit from the MBE/M. In conclusion, we argue that successful completion of the upcoming LEPs--with very aggressive schedule and funding restrictions--will depend on electronic model-based methods. We ask for a strong commitment from LEP managers throughout the Nuclear Weapons Complex to support deployment and use of MBE/M systems to meet their program needs.

Mobile/portable transuranic waste characterization systems at Los Alamos National Laboratory and a model for their use complex-wide  

SciTech Connect

Los Alamos National Laboratory has implemented mobile and portable characterization and repackaging systems to characterize TRU waste in storage for ultimate shipment and disposal at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, NM. These mobile systems are being used to characterize and repackage waste to meet the full requirements of the WIPP Waste Acceptance Criteria (WAC) and the WIPP Characterization Quality Assurance Program Plan (QAPP). Mobile and portable characterization and repackaging systems are being used to supplement the capabilities and throughputs of existing facilities. Utilization of mobile systems is a key factor that is enabling LANL to: (1) reduce its TRU waste work-off schedule from 36 years to 8.5 years; (2) eliminate the need to construct a $70M+ TRU waste characterization facility; (3) have waste certified for shipment to WIPP when WIPP opens; (4) continue to ship TRU waste to WIPP at the rate of 5000 drums per year; and, (5) reduce overall costs by more than $200M. Aggressive implementation of mobile and portable systems throughout the DOE complex through a centralized-distributed services model will result in similar advantages complex-wide.

Determination of Background Uranium Concentration in the Snake River Plain Aquifer under the Idaho National Engineering and Environmental Laboratory's Radioactive Waste Management Complex  

SciTech Connect

Uranium occurs naturally in the environment and is also a contaminant that is disposed of at the Radioactive Waste Management Complex (RWMC) at the Idaho National Engineering and Environmental Laboratory. To determine whether uranium concentrations in the Snake River Plain Aquifer, which underlies the laboratory, are elevated as a result of migration of anthropogenic uranium from the Subsurface Disposal Area in the RWMC, uranium background concentrations are necessary. Guideline values are calculated for total uranium, 234U, 235U, and 238U from analytical results from up to five datasets. Three of the datasets include results of samples analyzed using isotope dilution thermal ionization mass spectrometry (ID-TIMS) and two of the datasets include results obtained using alpha spectrometry. All samples included in the statistical testing were collected from aquifer monitoring wells located within 10 miles of the RWMC. Results from ID-TIMS and alpha spectrometry are combined when the data are not statistically different. Guideline values for total uranium were calculated using four of the datasets, while guideline values for 234U were calculated using only the alpha spectrometry results (2 datasets). Data from all five datasets were used to calculate 238U guideline values. No limit is calculated for 235U because the ID-TIMS results are not useful for comparison with routine monitoring data, and the alpha spectrometry results are too close to the detection limit to be deemed accurate or reliable for calculating a 235U guideline value. All guideline values presented represent the upper 95% coverage 95% confidence tolerance limits for background concentration. If a future monitoring result is above this guideline, then the exceedance will be noted in the quarterly monitoring report and assessed with respect to other aquifer information. The guidelines (tolerance limits) for total U, 234U, and 238U are 2.75 pCi/L, 1.92 pCi/L, and 0.90 pCi/L, respectively.

Hydrological, meteorological and geohydrological data for an unsaturated zone study near the Radioactive Waste Management Complex, Idaho National Engineering Laboratory, Idaho - 1987  

SciTech Connect

Since 1952, radioactive waste has been buried at the RWMC (Radioactive Waste Management Complex) at the Idaho National Engineering Laboratory in southeastern Idaho. In 1985, the US Geological Survey, in cooperation with the US Department of Energy, began a study of the geohydrology of the RWMC to provide a basis for estimating the extent of and the potential for migration of radionuclides in the unsaturated zone beneath the waste burial trenches and pits. This study is being conducted to provide hydrological, meteorological and geohydrological data for the test trench area adjacent to the northern boundary of the RWMC. During 1987, data were collected from the test trench area, where several types of instrumentation were installed in the surficial sediment in 1985. Hydrological data collected from both disturbed and undisturbed soil included measurements, from 28 thermocouple psychrometers placed at selected depths to about 6m. Soil moisture content measurements were collected bi-weekly in 9 neutron-probe access holes with a neutron moisture depth gage. Meteorological data summarized daily included: (1) incoming and emitted long-wave radiation; (2) incoming and reflected short-wave radiation; (3) air temperature; (4) relative humidity; (5) wind speed; (6) wind direction; and (7) precipitation. To describe grain-size distribution with depth, 17 samples were analyzed using sieve and pipette methods. Statistical parameters, carbonate content, color, particle roundness and sphericity, and mineralogic and clastic constituents were determined for each sample. Some samples were analyzed by x-ray diffraction techniques to determine bulk and clay mineralogy.

Geologic processes in the RWMC area, Idaho National Engineering Laboratory: Implications for long term stability and soil erosion at the radioactive waste management complex  

SciTech Connect

The Radioactive Waste Management Complex (RWMC) is the disposal and storage facility for low-level radioactive waste at the Idaho National Engineering Laboratory (INEL). Transuranic waste and mixed wastes were also disposed at the RWMC until 1970. It is located in the southwestern part of the INEL about 80 km west of Idaho Falls, Idaho. The INEL occupies a portion of the Eastern Snake River Plain (ESRP), a low-relief, basalt, and sediment-floored basin within the northern Rocky Mountains and northeastern Basin and Range Province. It is a cool and semiarid, sagebrush steppe desert characterized by irregular, rolling terrain. The RWMC began disposal of INEL-generated wastes in 1952, and since 1954, wastes have been accepted from other Federal facilities. Much of the waste is buried in shallow trenches, pits, and soil vaults. Until about 1970, trenches and pits were excavated to the basalt surface, leaving no sediments between the waste and the top of the basalt. Since 1970, a layer of sediment (about 1 m) has been left between the waste and the basalt. The United States Department of Energy (DOE) has developed regulations specific to radioactive-waste disposal, including environmental standards and performance objectives. The regulation applicable to all DOE facilities is DOE Order 5820.2A (Radioactive Waste Management). An important consideration for the performance assessment of the RWMC is the long-term geomorphic stability of the site. Several investigators have identified geologic processes and events that could disrupt a radioactive waste disposal facility. Examples of these {open_quotes}geomorphic hazards{close_quotes} include changes in stream discharge, sediment load, and base level, which may result from climate change, tectonic processes, or magmatic processes. In the performance assessment, these hazards are incorporated into scenarios that may affect the future performance of the RWMC.

Laboratory Simulations  

NASA Astrophysics Data System (ADS)

Geophysical properties of near-Earth objects (NEOs) can best be studied using radio tomography and seismology. Reflection and transmission radio tomography is best suited for measuring the complex electric permittivity of poorly conducting materials to reveal the internal structure of NEOs. Such NEOs are primarily comet nuclei and carbonaceous asteroids. Seismic experiments are most suitable for studying elastic properties of consolidated materials to reveal material strengths of stony and iron-nickel asteroids. Thus, the two methods are complementary for investigating comets and asteroids of all types. Analysis of reflection and transmission radio tomography of heterogeneous irregular shaped bodies is very difficult. Scattering by internal and outer boundaries, differences in the refractive indices of heterogeneous materials, and attenuation by electric conductivity complicate the analyses. For this reason laboratory simulations with scaled objects and scaled wavelengths is extremely useful to check the reliability of inversion techniques of radio signals to arrive at the interior structure of an NEO. Another approach to obtaining quantitative information on the composition and structure of an NEO is through induced seismology. There are two approaches to producing seismic waves: small explosive charges and impactors. Experimental work has been performed in the laboratory to examine the impulse delivered by explosives. Wave travel times can be used to back out basic material properties and first order structure of an NEO. For example, if distinct arrival pulses for P and S waves are recorded and the explosive initiation/impact time and location are known, then it is possible to determine the elastic properties of bulk and shear modulus. Reflections in the seismograms allow a determination of material boundaries in an NEO. Original arrival time is important since Q numbers for stony NEO material are presumed to be high, as they were on the Moon, and thus it is expected that there will be extensive ringing and noise. Other types of NEO materials will have differing seismic characteristics.

The possibility that the organic molecules that have been found near comets could have formed by UV photolysis of interstellar ices was investigated by simulating this process in the laboratory. It is found that oxygen rich organics containing C-OH, C-H and C=O groups are readily produced in this way. These results indicate that part of the organic material in comets may have formed by UV irradiation of ices, either in the pre-solar nebula or in the interstellar phase. PMID:11538153

However, laboratories that confirm the time complexity of algorithms can be tedious exercises that do not really challenge a student to think about the algorithms they are testing. By giving students a set of unknown executables,

Lunar laboratory  

SciTech Connect

An international research laboratory can be established on the Moon in the early years of the 21st Century. It can be built using the transportation system now envisioned by NASA, which includes a space station for Earth orbital logistics and orbital transfer vehicles for Earth-Moon transportation. A scientific laboratory on the Moon would permit extended surface and subsurface geological exploration; long-duration experiments defining the lunar environment and its modification by surface activity; new classes of observations in astronomy; space plasma and fundamental physics experiments; and lunar resource development. The discovery of a lunar source for propellants may reduce the cost of constructing large permanent facilities in space and enhance other space programs such as Mars exploration. 29 refs.

Geology of the Arco-Big Southern Butte area, eastern Snake River Plain, and volcanic hazards to the radioactive waste management complex, and other waste storage and reactor facilities at the Idaho National Engineering Laboratory, Idaho  

USGS Publications Warehouse

The Arco-Big Southern Butte area of the eastern Snake River Plain, Idaho, includes a volcanic rift zone and more than 70 Holocene and late Quaternary basalt volcanoes. The Arco volcanic rift zone extends southeast for 50 km from Arco to about 10 km southeast of Big Southern Butte. The rift zone is the locus of extensional faults, graben, fissure basaltic volcanic vents, several rhyolite domes at Big Southern Butte, and a ferrolatite volcano at Cedar Butte. Limited radiometric age data and geological field criteria suggest that all volcanism in the area is younger than 700,000 years; at least 67 separate basaltic eruptions are estimated to have occurred within the last 200,000 years. The average volcanic recurrence interval for the Arco-Big Southern Butte area is approximately one eruption per 3,000 years. Radioactive waste storage and reactor facilities at the Idaho National Engineering Laboratory may be subject to potential volcanic hazards. The geologic history and inferred past volcanic events in the Arco-Big Southern Butte area provide a basis for assessing the volcanic hazard. It is recommended that a radiometric age-dating study be performed on rocks in cored drill holes to provide a more precise estimate of the eruption recurrence interval for the region surrounding and including the Radioactive Waste Management Complex. It is also recommended that several geophysical monitoring systems (dry tilt and seismic) be installed to provide adequate warning of future volcanic eruptions.

The website for the Virtual Laboratory contains a bold and direct statement: "Conventional teaching all too often accepts memorization and pattern recognition as true learning" After reading this statement, it makes sense that the goal of this site is "to help students to recognize, confront, correct, and expand their understanding of subject or a technique." The site contains five different sets of course materials that use interactive materials, short quizzes, and embedded demonstrations to assist students and teachers alike. One set of materials that should not be missed is in the Teaching & Learning Biology area. Here visitors will find links, fact sheets, and pedagogical suggestions for teaching a college-level biology course. Moving on, the Chemistry, Life, the Universe and Everything section contains a new perspective on how to reform the garden-variety general chemistry course.

Synthesis of n2-Dihydrogen Complex, trans-{Fe(n2H2)(H)[1,2-bis(diphenylphosphino)-ethane]2}[BF4]: An Experiment for an Advanced Inorganic Chemistry Laboratory Involving Synthesis and NMR Properties of an n2-H2 Complex  

NASA Astrophysics Data System (ADS)

An experiment for an advanced inorganic chemistry laboratory involving synthesis and NMR properties of the molecular hydrogen complex [Fe(n2-H2)(H)(dppe)2](BF4) (1) (dppe = 1,2-bis(diphenylphosphino)ethane) is described. The precursor to the dihydorgen complex, Fe(H)2(dppe)2, is prepared by refluxing anhydrous FeCl2 with excess dppe and NaBH4 under an inert atmosphere. Protonation of the dihydride with HBF4 · O(C2H5)2 under an argon or hydrogen atmosphere generates 1 in 80% yield. Exchange of the hydride ligand with the hydrogen atoms of the dihydrogen ligand can be demonstrated in a variable temperature 1H NMR experiment for 1. Preparation of the deuterated analog of 1, [Fe(n2-HD)(H)(dppe)2](BF4) by reaction of Fe(H)2(dppe)2 with DBF4, allows measurement of the H-D coupling constant, a characteristic parameter of a molecular hydrogen compound.

Review of the transport of selected radionuclides in the interim risk assessment for the Radioactive Waste Management Complex, Waste Area Group 7 Operable Unit 7-13/14, Idaho National Engineering and Environmental Laboratory, Idaho  

USGS Publications Warehouse

The U.S. Department of Energy (DOE) requested that the U.S. Geological Survey conduct an independent technical review of the Interim Risk Assessment (IRA) and Contaminant Screening for the Waste Area Group 7 (WAG-7) Remedial Investigation, the draft Addendum to the Work Plan for Operable Unit 7-13/14 WAG-7 comprehensive Remedial Investigation and Feasibility Study (RI/FS), and supporting documents that were prepared by Lockheed Martin Idaho Technologies, Inc. The purpose of the technical review was to assess the data and geotechnical approaches that were used to estimate future risks associated with the release of the actinides americium, uranium, neptunium, and plutonium to the Snake River Plain aquifer from wastes buried in pits and trenches at the Subsurface Disposal Area (SDA). The SDA is located at the Radioactive Waste Management Complex in southeastern Idaho within the boundaries of the Idaho National Engineering and Environmental Laboratory. Radionuclides have been buried in pits and trenches at the SDA since 1957 and 1952, respectively. Burial of transuranic wastes was discontinued in 1982. The five specific tasks associated with this review were defined in a ?Proposed Scope of Work? prepared by the DOE, and a follow-up workshop held in June 1998. The specific tasks were (1) to review the radionuclide sampling data to determine how reliable and significant are the reported radionuclide detections and how reliable is the ongoing sampling program, (2) to assess the physical and chemical processes that logically can be invoked to explain true detections, (3) to determine if distribution coefficients that were used in the IRA are reliable and if they have been applied properly, (4) to determine if transport model predictions are technically sound, and (5) to identify issues needing resolution to determine technical adequacy of the risk assessment analysis, and what additional work is required to resolve those issues.

Multicellular microorganisms: laboratory versus nature  

PubMed Central

Our present in-depth knowledge of the physiology and regulatory mechanisms of microorganisms has arisen from our ability to remove them from their natural, complex ecosystems into pure liquid cultures. These cultures are grown under optimized laboratory conditions and allow us to study microorganisms as individuals. However, microorganisms naturally grow in conditions that are far from optimal, which causes them to become organized into multicellular communities that are better protected against the harmful environment. Moreover, this multicellular existence allows individual cells to differentiate and acquire specific properties, such as forming resistant spores, which benefit the whole population. The relocation of natural microorganisms to the laboratory can result in their adaptation to these favourable conditions, which is accompanied by complex changes that include the repression of some protective mechanisms that are essential in nature. Laboratory microorganisms that have been cultured for long periods under optimized conditions might therefore differ markedly from those that exist in natural ecosystems.

The laboratory workforce shortage: a managerial perspective.  

PubMed

Most clinical laboratories in the nation report severe difficulties in recruitment and retention of most types of personnel. Other important factors impacting this problem include work complexities, increased automation, and a graying workforce. As a further challenge, institutional needs for clinical laboratory personnel are expected to grow significantly in the next decade. This article examines the current situation of the clinical laboratory workforce. It analyzes the different types of personnel; the managerial, supervision, and line positions that are key for different types of laboratories; the job outlook and recent projections for different types of staff; and the current issues, trends, and challenges of the laboratory workforce. Laboratory managers need to take action with strategies suggested for overcoming these challenges. Most importantly, they need to become transformational leaders by developing effective staffing models, fostering healthy and productive work environments, and creating value with a strategic management culture and implementation of knowledge management.

Laboratory test system. Final report  

SciTech Connect

This project was initiated to develop a laboratory test capability for evaluating new and existing digital product designs. In recent years, Bendix Kansas City has become more active in syppling early development hardware to the design laboratories for evaluation. Because of the more complex electronic designs being used in new components, more highly automated test systems are needed to evaluate development hardware. To meet this requirement, a universal test system was developed to provide both basic test capabilities and flexibility to adapt easily to specific product applications. This laboratory evaluation system will reduce the need to develop complex dedicated test systems for each new product design, while still providing the benefits of an automated system. A special purpose interface chassis was designed and fabricated to permit a standardized interface between the test system and the product application. Connector assignments by system functions provide convenience and function isolation. Standard cables were used to reduce the need for special purpose hardware. Electrical testing of a developmental electronics assembly demonstrated the adaptability of this system for a typical product application. Both the interface hardware and the software were developed for this application.

SIGLa: an adaptable LIMS for multiple laboratories  

PubMed Central

Background The need to manage large amounts of data is a clear demand for laboratories nowadays. The use of Laboratory Information Management Systems (LIMS) to achieve this is growing each day. A LIMS is a complex computational system used to manage laboratory data with emphasis in quality assurance. Several LIMS are available currently. However, most of them have proprietary code and are commercialized with a high cost. Moreover, due to its complexity, LIMS are usually designed to comply with the needs of one kind of laboratory, making it very difficult to reuse a LIMS. In this work we describe the Sistema Integrado de Gerncia de Laboratrios (SIGLa), an open source LIMS with a new approach designed to allow it to adapt its activities and processes to various types of laboratories. Results SIGLa incorporates a workflow management system, making it possible to create and manage customized workflows. For each new laboratory a workflow is defined with its activities, rules and procedures. During the execution, for each workflow created, the values of attributes defined in a XPDL file (which describe the workflow) are stored in SIGLas database, allowing then to be managed and retrieved upon request. These characteristics increase systems flexibility and extend its usability to include the needs of multiple types of laboratories. To construct the main functionalities of SIGLa a workflow of a proteomic laboratory was first defined. To validate the SIGLa capability of adapting to multiples laboratories, on this paper we study theprocess and the needs of a microarray laboratory and define its workflow. This workflow has been defined in a period of about two weeks, showing the efficiency and flexibility of the tool. Conclusions Using SIGLa it has been possible to construct a microarray LIMS in a few days illustrating the flexibility and power of the method proposed. With SIGLas development we hope to contribute positively to the area of management of complex data in laboratory by managing its large amounts of data, guaranteeing the consistence of the data and increasing the laboratory productivity. We also hope to make possible to laboratories with little resources to afford a high level system for complex data management.

The quest for complex molecules in space: laboratory spectroscopy of n-butyl cyanide, n-C4H9CN, in the millimeter wave region and its astronomical search in Sagittarius B2(N)  

NASA Astrophysics Data System (ADS)

Context. The saturated n-propyl cyanide was recently detected in Sagittarius B2(N). The next largest unbranched alkyl cyanide is n-butyl cyanide. Aims: We provide accurate rest frequency predictions beyond the millimeter wave range to search for this molecule in the Galactic center source Sagittarius B2(N) and facilitate its detection in space. Methods: We investigated the laboratory rotational spectrum of n-butyl cyanide between 75 GHz and 348 GHz. We searched for emission lines produced by the molecule in our sensitive IRAM 30 m molecular line survey of Sagittarius B2(N). Results: We identified more than one thousand rotational transitions in the laboratory for each of the three conformers for which limited data had been obtained previously in a molecular beam microwave study. The quantum number range was greatly extended to J ? 120 or more and Ka > 35, resulting in accurate spectroscopic parameters and accurate rest frequency calculations up to about 500 GHz for strong to moderately weak transitions of the two lower energy conformers. Upper limits to the column densities of N ? 3 1015 cm-2 and 8 1015 cm-2 were derived towards Sagittarius B2(N) for the two lower energy conformers, anti-anti and gauche-anti, respectively. Conclusions: Our present data will be helpful for identifying n-butyl cyanide at millimeter or longer wavelengths with radio telescope arrays such as ALMA, NOEMA, or EVLA. In particular, its detection in Sagittarius B2(N) with ALMA seems feasible.

During the Civil War, the scarcity and expense of imported drugs forced the Confederate Army to establish several medical laboratories to manufacture drugs for military use. The laboratories produced medicines from indigenous plants and also made non-plant-based drugs. The Confederate Surgeon General and the Chief Purveyor in Richmond, VA, coordinated activities of most of the laboratories. The laboratories employed talented and resourceful personnel and manufactured a large volume and wide variety of drugs, the most useful of which included ether, chloroform, and opiates. The pharmaceutical quality of the laboratories' output was evidently uneven. Empirical testing in military hospitals helped determine the clinical value of indigenous remedies. The Confederate medical laboratories participated in a coordinated effort to supply the Army with substitutes for drugs whose availability was curtailed or uncertain. PMID:14696874

The Virtual Robotics Laboratory  

SciTech Connect

The growth of the Internet has provided a unique opportunity to expand research collaborations between industry, universities, and the national laboratories. The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations.

Use of the Oak Ridge National Laboratory tungsten-188/rhenium-188 generator for preparation of the rhenium-188 HDD/lipiodol complex for trans-arterial liver cancer therapy  

SciTech Connect

This work describes the installation, use, and quality control (QC) of the alumina-based tungsten-188 ({sup 188}W)/rhenium-188 ({sup 188}Re) generators provided by the Oak Ridge National Laboratory (ORNL). In addition, methods used for concentration of the {sup 188}Re-perrhenate bolus and preparation of {sup 188}Re-labeled HDD (4-hexadecyl-2,2,9,9-tetramethyl-4,7-diaza-1,10-decanethiol) for trans-arterial administration for therapy of nonresectable liver cancer also are described. The {sup 188}W/{sup 188}Re generator has a long useful shelf-life of several months and is a convenient on-site {sup 188}Re production system. {sup 188}Re has excellent therapeutic and imaging properties (T{sub 1/2} 16.9 hours; E{sub {beta}max} 2.12 MeV; 155-keV gamma ray, 15%) and is cost effectively obtained on demand by saline elution of the generator. The clinical efficacy of a variety of {sup 188}Re-labeled agents has been demonstrated for several therapeutic applications. Because of the favorable physical properties of {sup 188}Re, several {sup 188}Re-labeled agents are being developed and evaluated for the treatment of nonresectable/refractory liver cancer. {sup 188}Re-labeled HDD has been the most widely studied of these agents for this application and has been introduced into clinical trials at a number of institutions. The trans-arterial administration of {sup 188}Re-labeled agents for treatment of inoperable liver cancer requires use of high-level (1-2 Ci) {sup 188}W/{sup 188}Re generators. The handling of such high levels of {sup 188}Re imposes radiological precautions normally not encountered in a radiopharmacy and adequate care and ALARA (i.e., 'As Low As Reasonably Achievable') principles must be followed. The ORNL generator provides consistently high {sup 188}Re yields (>75%) and low {sup 188}W parent breakthrough (<10{sup -3}%) over an extended shelf-life of several months. However, the high elution volumes (20-40 mL for 1-2 Ci generators) can require concentration of the {sup 188}Re bolus by postelution passage through silver cation chloride trapping columns used in the cost-effective tandem cation/anion column system. The silver column removes the high levels of chloride anion as insoluble AgCl, thus allowing subsequent specific trapping of the perrhenate anion on the small (QMA SeaPak) anion column. This method permits subsequent elution of {sup 188}Re-perrhenate with a small volume of saline, providing a very high activity-concentration solution. Because the {sup 188}Re-specific volume-activity concentration continually decreases with time, the tandem system is especially effective method for extending the useful generator shelf-life. Low elution flow rates (<1 mL/min) minimize any high back pressure which may be encountered during generator/tandem column elution when using tightly packed, small-particle-size commercial columns. In-house preparation of silver cation columns is recommended since the chloride trapping capacity is essentially unlimited, it is inexpensive and not limited in availability to any one supplier, and back pressure can be eliminated by the use of larger particles. Methods for the preparation of {sup 188}Re-HDD have been optimized and this agent can be obtained in high yield (80%).

Software agent technology in the laboratory  

SciTech Connect

The IT (Information Technology) environment in today's laboratories is characterized as being highly distributed, heterogeneous, and in some instances extremely dynamic. Larger organizations have to deal with hundreds of different systems, ranging from standalone workstations and devices in laboratories to fully integrated LIMS (Laboratory Information Management System) and ERP (Enterprise Resource Planning) systems. An information system operating in such an environment must handle several emerging problems, such as heterogeneous hardware and software platforms, as well as distributed information sources and capabilities. It is also expected that the IT infrastructure scales well, easily integrates with legacy systems, allows resource sharing, and supports day-to-day operations such as information retrieval, data storage, validation, tracking, replication, and archival in a fully automated fashion. By using real-world examples, this presentation will illustrate how software agent technology can be used to manage the ever increasing IT complexity and user demands in the laboratory of the future.

Carbon Characterization Laboratory Report  

SciTech Connect

The newly completed Idaho National Laboratory (INL) Carbon Characterization Laboratory (CCL) is located in Lab-C20 of the Idaho National Laboratory Research Center. This laboratory was established under the Next Generation Nuclear Plant (NGNP) Project to support graphite research and development activities. The CCL is designed to characterize and test carbon-based materials such as graphite, carbon-carbon composites, and silicon-carbide composite materials. The laboratory is fully prepared to measure material properties for nonirradiated carbon-based materials. Plans to establish the laboratory as a radiological facility within the next year are definitive. This laboratory will be modified to accommodate irradiated materials, after which it can be used to perform material property measurements on both irradiated and nonirradiated carbon-based material. Instruments, fixtures, and methods are in place for preirradiation measurements of bulk density, thermal diffusivity, coefficient of thermal expansion, elastic modulus, Youngs modulus, Shear modulus, Poisson ratio, and electrical resistivity. The measurement protocol consists of functional validation, calibration, and automated data acquisition.

Laboratory-acquired infections.  

PubMed

Laboratory-acquired infections due to a wide variety of bacteria, viruses, fungi, and parasites have been described. Although the precise risk of infection after an exposure remains poorly defined, surveys of laboratory-acquired infections suggest that Brucella species, Shigella species, Salmonella species, Mycobacterium tuberculosis, and Neisseria meningitidis are the most common causes. Infections due to the bloodborne pathogens (hepatitis B virus, hepatitis C virus, and human immunodeficiency virus) remain the most common reported viral infections, whereas the dimorphic fungi are responsible for the greatest number of fungal infections. Because of the increasing attention on the role of the laboratory in bioterrorism preparation, I discuss the risk of laboratory-acquired infection with uncommon agents, such as Francisella tularensis and Bacillus anthracis. Physicians who care for a sick laboratory worker need to consider the likelihood of an occupationally acquired infection while advising exposed laboratory workers about postexposure prophylaxis. In addition, physicians should be aware of the importance of alerting the laboratory if infection with a high-risk agent is suspected. PMID:19480580

Laboratory simulation of volcano seismicity.  

PubMed

The physical processes generating seismicity within volcanic edifices are highly complex and not fully understood. We report results from a laboratory experiment in which basalt from Mount Etna volcano (Italy) was deformed and fractured. The experiment was monitored with an array of transducers around the sample to permit full-waveform capture, location, and analysis of microseismic events. Rapid post-failure decompression of the water-filled pore volume and damage zone triggered many low-frequency events, analogous to volcanic long-period seismicity. The low frequencies were associated with pore fluid decompression and were located in the damage zone in the fractured sample; these events exhibited a weak component of shear (double-couple) slip, consistent with fluid-driven events occurring beneath active volcanoes.

A set of non-traditional astronomy laboratories for non-science majors will be presented along with evaluations of lab technicians (these labs were originally developed at the College of Staten Island of the City University of New York). The goal of these labs is twofold: (a) to provide the students with hands-on experiences of scientific methodology and (b) to provoke critical thinking. Because non-science majors are often rather resistant to learning the relevant methodology - and especially to thinking critically - this manual is structured differently. It does not only provide traditional cook-book recipes but also contains several leading questions to make the students realize why they are doing what. The students are encouraged to write full sentences and explain how they reach which conclusions. This poster summarizes the experiences of the laboratory assistants that worked with the instructor and presents how they judge the effectiveness of the laboratories.

Gas measurement laboratory  

SciTech Connect

The Lone Star Gas Company gas analysis laboratory has accommodated nearly a 5-fold increase in the sample processing load during the past five years. This has been accomplished through the construction of carefully planned facilities, the acquisition and judicious application of instrumentation, and the development of an automated data handling system. Well planned facilities have resulted in smooth work flow patterns and an increase in productivity. Judicious application of instrumentation has significantly increased processing capacity and resulted in more accurate analyses. Well designed computer programs have automated sample processing functions, reduced the potential for human error, and improved laboratory management by providing timely access to required information. Planning is essential for staying ahead of growing analysis needs. The gas analysis laboratory now has the processing capacity, equipment growth potential, and the information management systems to respond to the energy measurement demands of the future.

Systems integration test laboratory application & experiences  

NASA Astrophysics Data System (ADS)

The ability to safely control highly dynamic systems is of prime importance to designers. Whether the system is an aircraft, spacecraft, or propulsion system, control system designers must turn to test laboratories not only to verify and validate the control systems, but also to actually use the laboratory as a design and development tool. The use of the laboratory early in the development phase of a system-prior to committing to actual hardware/software (HW/SW)-permits early detection of system anomalies, thereby minimizing program development costs while enhancing safety. Later the laboratory can be used to train system operators (for example, pilots, ground crew) in preparation for flight/ground test. In the case of the statically unstable X-29 forward swept wing aircraft, a comprehensive real-time, hardware-in-the-loop test facility was critical in the development of the aircraft's digital fly-by-wire (FBW) flight control system. The X-29 laboratory initially was used to introduce control laws to a simulated real-time environment to verify control system characteristics. Later, actual flight hardware was introduced to the laboratory, at which point the formal system verification/validation test program began. The test program utilized detailed test plans and procedures derived from system requirements and specifications to map out all tests required. This assured that the maximum number of components of the system were exercised in the laboratory, and all components tested had traceability throughout the test program. The end-to-end hardware-in-the loop simulation provided the environment to perform critical failure modes testing, parameter sensitivity evaluation and ultimately pilot/ground crew training during normal and degraded flight control system operation. The X-29 test experience, applicable to the laboratory testing of all critical control systems, has ingrained the philosophy that successful development of complex systems requires an orderly build-up of complexity within the laboratory. By this we mean that components of the simulation are introduced to the laboratory only when previous additions are well understood and formally verified by prescribed testing procedures. First, non-real-time computer models of the system are developed (for example, stability derivatives from scale model wind tunnel data). Upon reaching a level of maturity, these non-real-time codes are implemented and verified in a real-time environment. The real-time implementation is important because it lends itself to interfacing with actual flight hardware and software for final verification/validation (V/V) and training. This philosophy of laboratory management for critical control systems test is not limited to aircraft applications. Any dynamic control system could be developed and tested in a fashion similar to the X-29 control system. The gradual buildup of complexity in the laboratory commencing with non-real-time math modeling, leading to real-time, hard-ware-in-the-loop validation and ultimately operator training is a necessary procedure for obtaining safe, reliable systems. This paper discusses the experience gained from the development of the X-29 digital flight control system, use of the laboratory for development, verification and validation, and how this test philosophy is applied to any system.

Revitalizing chemistry laboratory instruction  

NASA Astrophysics Data System (ADS)

This dissertation involves research in three major domains of chemical education as partial fulfillment of the requirements for the Ph.D. program in chemistry at Miami University with a major emphasis on chemical education, and concurrent study in organic chemistry. Unit I, Development and Assessment of a Column Chromatography Laboratory Activity, addresses the domain of Instructional Materials Development and Testing. This unit outlines the process of developing a publishable laboratory activity, testing and revising that activity, and subsequently sharing that activity with the chemical education community. A laboratory activity focusing on the separation of methylene blue and sodium fluorescein was developed to demonstrate the effects of both the stationary and mobile phase in conducting a separation. Unit II, Bringing Industry to the Laboratory, addresses the domain of Curriculum Development and Testing. This unit outlines the development of the Chemistry of Copper Mining module, which is intended for use in high school or undergraduate college chemistry. The module uses the learning cycle approach to present the chemistry of the industrial processes of mining copper to the students. The module includes thirteen investigations (three of which are web-based and ten which are laboratory experiments) and an accompanying interactive CD-ROM, which provides an explanation of the chemistry used in copper mining with a virtual tour of an operational copper mine. Unit III, An Alternative Method of Teaching Chemistry. Integrating Lecture and the Laboratory, is a project that addresses the domain of Research in Student Learning. Fundamental Chemistry was taught at Eastern Arizona College as an integrated lecture/laboratory course that met in two-hour blocks on Monday, Wednesday, and Friday. The students taking this integrated course were compared with students taking the traditional 1-hour lectures held on Monday, Wednesday, and Friday, with accompanying 3-hour lab on Tuesday or Thursday. There were 119 students in the test group, 522 students in the Shelton control group and 556 students in the McBride control group. Both qualitative data and quantitative data were collected. A t-test was used to test significance.

Undergraduate Laboratory for Surface Science  

NASA Astrophysics Data System (ADS)

Surface science has developed into a multidisciplinary field of research with applications ranging from heterogeneous catalysis to semiconductor etching (1). Aspects of surface chemistry are now included in physical chemistry textbooks (2) and undergraduate curricula (3), but the perceived cost and complexity of equipment has deterred the introduction of surface science methods in undergraduate laboratories (4). Efforts to expose chemistry undergraduates to state-of-the-art surface instrumentation have just begun (5). To provide our undergraduates with hands-on experience in using standard techniques for characterizing surface morphology, adsorbates, kinetics, and reaction mechanisms, we have developed a set of surface science experiments for our physical chemistry laboratory sequence. The centerpiece of the laboratory is an ultrahigh vacuum (UHV) chamber for studies of single crystal surfaces. This instrument, shown in the figure, has surface analysis capabilities including low energy electron diffraction (LEED), Auger spectroscopy, and temperature-programmed desorption (TPD). The laboratory exercises involve experiments on the well-studied Pt(111) surface. Students prepare a previously mounted single crystal sample by sputtering it with an argon ion gun and heating it under O2. Electron diffraction patterns from the cleaned surface are then obtained with a reverse view LEED apparatus (Princeton Instruments). Images are captured by a charge-coupled device (CCD) camera interfaced to a personal computer for easy downloading and subsequent analysis. Although the LEED images from a Pt(111) surface can be readily interpreted using simple diffraction arguments, this lab provides an excellent context for introducing Miller indices and reciprocal lattices (6). The surface chemical composition can be investigated by Auger spectroscopy, using the LEED apparatus as a simple energy analyzer. The temperature programmed desorption experiment, which is nearly complete, will be be added to the curriculum this academic year. This experiment introduces students to the concepts of surface adsorption and desorption kinetics. The sample mount can be both heated to 900 oC and cooled by liquid nitrogen, allowing the study of the desorption of a variety of adsorbates, both chemisorbed and physisorbed. Adsorbed species evolving from the heated surface are detected with a quadrupole mass spectrometer. Initially, students will study the desorption kinetics of CO from a Pt(111) surface for a range of coverages and temperature programming rates in order to obtain rate parameters and to test the validity of Redhead's relationship between the activation energy of desorption and the peak desorption temperature. They then will be introduced to the mechanisms of surface reactions (Langmuir-Hinshelwood) in a study of CO oxidation on this surface. We have also set up a scanning tunneling microscopy (STM) laboratory using a commercially available instrument (Burleigh Instruments, Inc.), which complements the UHV surface structure experiments by introducing the topography of a real surface, for example, with steps and defect sites. With the apparatus now completed, we can explore other possible developments, for example, an applied physics track designed around experiments on semiconductor substrates. Future additions include X-ray photoelectron spectroscopy and completion of a separate surface infrared spectroscopy experiment on supported catalysts. We acknowledge support from the National Science Foundation, Division of Undergraduate Education Instrumentation and Laboratory Improvement (ILI) Program (Grant No. DUE-9352254) and an AT&T Special Purpose Grant.

Laboratory Evaluation of Anemia  

PubMed Central

The laboratory evaluation of anemia begins with a complete blood count and reticulocyte count. The anemia is then categorized as microcytic, macrocytic or normocytic, with or without reticulocytosis. Examination of the peripheral smear and a small number of specific tests confirm the diagnosis. The serum iron level, total iron-binding capacity, serum ferritin level and hemoglobin electrophoresis generally separate the microcytic anemias. The erythrocyte size-distribution width may be particularly helpful in distinguishing iron deficiency from thalassemia minor. Significant changes have occurred in the laboratory evaluation of macrocytic anemia, and a new syndrome of nitrous oxide-induced megaloblastosis and neurologic dysfunction has been recognized. A suggested approach to the hemolytic anemias includes using the micro-Coombs' test and ektacytometry. Finally, a number of causes have been identified for normocytic anemia without reticulocytosis, including normocytic megaloblastic anemia and the acquired immunodeficiency syndrome.

Launched to the MIR station in 1996, this laboratory was set up and used for the first time by Claudie Andr-Deshays during the French mission ? Cassiopeia ?. The scientific program is performed pre, post and in-flight to study phenomena related to the transition to microgravity as well as the return to the earth conditions. Particular emphasis was placed on the development of the real-time telemetry to monitor LBNP test. This function was successfull during the Cassiopeia mission, providing the medical team at TSOUP (MIR Control Center in Moscow) with efficient means to control the physiological state of the cosmonaut. Based on the results of this first mission, IMBP and CNES will go on using Physiolab with Russian crews. CNES will take advantage of the upcoming French missions on MIR to improve the system, and intends to develop a new laboratory for the International Space Station.

Sandia National Laboratories is a multiprogram engineering laboratory that serves the nation through the Department of Energy (DOE), both in its programs and those of other agencies. Major research and development responsibilities cover nuclear weapons, arms control, energy, environment and other areas of strategic importance to national security. The principal mission is to support national defense policies by ensuring that the nuclear weapon stockpile meets the highest standards of safety, security, control and military performance. In May of 1968, the Albuquerque Office of DOE (then AEC) assigned the Quality Assurance function to Sandia Laboratories on all products for which Sandia has design responsibility. The Sandia Quality Improvement Plan presents a Quality Management System that integrates the Sandia quality policies and several independent improvement processes into a cohesive structure. This structure guides day-to-day operations toward strategic objectives. The Sandia Quality Policy provides the underlying principles for the management of our research and engineering efforts and establishes our customers as the central focus of our Sandia quality improvement efforts. Operationally, these efforts are centered around quality improvement processes based on good management practices developed by AT T, and progress is measured against the Malcolm Baldridge National Quality Award criteria. Developing a comprehensive plan based on these processes requires that we determine where we are, where we want to be, and how we measure our progress. 1 fig. (JF)

The purpose of this study is to elucidate the issues involved in developing a Laboratory Microfusion Capability (LMC) which is the major objective of the Inertial Confinement Fusion (ICF) program within the purview of the Department of Energy's Defense Programs. The study was initiated to support a number of DOE management needs: to provide insight for the evolution of the ICF program; to afford guidance to the ICF laboratories in planning their research and development programs; to inform Congress and others of the details and implications of the LMC; to identify criteria for selection of a concept for the Laboratory Microfusion Facility and to develop a coordinated plan for the realization of an LMC. As originally proposed, the LMC study was divided into two phases. The first phase identifies the purpose and potential utility of the LMC, the regime of its performance parameters, driver independent design issues and requirements, its development goals and requirements, and associated technical, management, staffing, environmental, and other developmental and operational issues. The second phase addresses driver-dependent issues such as specific design, range of performance capabilities, and cost. The study includes four driver options; the neodymium-glass solid state laser, the krypton fluoride excimer gas laser, the light-ion accelerator, and the heavy-ion induction linear accelerator.

Benchmarking and the laboratory  

PubMed Central

This article describes how benchmarking can be used to assess laboratory performance. Two benchmarking schemes are reviewed, the Clinical Benchmarking Company's Pathology Report and the College of American Pathologists' Q-Probes scheme. The Clinical Benchmarking Company's Pathology Report is undertaken by staff based in the clinical management unit, Keele University with appropriate input from the professional organisations within pathology. Five annual reports have now been completed. Each report is a detailed analysis of 10 areas of laboratory performance. In this review, particular attention is focused on the areas of quality, productivity, variation in clinical practice, skill mix, and working hours. The Q-Probes scheme is part of the College of American Pathologists programme in studies of quality assurance. The Q-Probes scheme and its applicability to pathology in the UK is illustrated by reviewing two recent Q-Probe studies: routine outpatient test turnaround time and outpatient test order accuracy. The Q-Probes scheme is somewhat limited by the small number of UK laboratories that have participated. In conclusion, as a result of the government's policy in the UK, benchmarking is here to stay. Benchmarking schemes described in this article are one way in which pathologists can demonstrate that they are providing a cost effective and high quality service. Key Words: benchmarking pathology

The detection of Entamoeba histolytica, the causative agent of amebiasis, is an important goal of the clinical microbiology laboratory. To assess the scope of E. histolytica infection, it is necessary to utilize accurate diagnostic tools. As more is discovered about the molecular and cell biology of E. histolytica, there is great potential for further understanding the pathogenesis of amebiasis. Molecular biology-based diagnosis may become the technique of choice in the future because establishment of these protozoa in culture is still not a routine clinical laboratory process. In all cases, combination of serologic tests with detection of the parasite (by antigen detection or PCR) offers the best approach to diagnosis, while PCR techniques remain impractical in many developing country settings. The detection of amebic markers in serum in patients with amebic colitis and liver abscess appears promising but is still only a research tool. On the other hand, stool antigen detection tests offer a practical, sensitive, and specific way for the clinical laboratory to detect intestinal E. histolytica. All the current tests suffer from the fact that the antigens detected are denatured by fixation of the stool specimen, limiting testing to fresh or frozen samples.

Smart Grid Integration Laboratory  

SciTech Connect

The initial federal funding for the Colorado State University Smart Grid Integration Laboratory is through a Congressionally Directed Project (CDP), DE-OE0000070 Smart Grid Integration Laboratory. The original program requested in three one-year increments for staff acquisition, curriculum development, and instrumentation ?? all which will benefit the Laboratory. This report focuses on the initial phase of staff acquisition which was directed and administered by DOE NETL/ West Virginia under Project Officer Tom George. Using this CDP funding, we have developed the leadership and intellectual capacity for the SGIC. This was accomplished by investing (hiring) a core team of Smart Grid Systems engineering faculty focused on education, research, and innovation of a secure and smart grid infrastructure. The Smart Grid Integration Laboratory will be housed with the separately funded Integrid Laboratory as part of CSU??s overall Smart Grid Integration Center (SGIC). The period of performance of this grant was 10/1/2009 to 9/30/2011 which included one no cost extension due to time delays in faculty hiring. The Smart Grid Integration Laboratory??s focus is to build foundations to help graduate and undergraduates acquire systems engineering knowledge; conduct innovative research; and team externally with grid smart organizations. Using the results of the separately funded Smart Grid Workforce Education Workshop (May 2009) sponsored by the City of Fort Collins, Northern Colorado Clean Energy Cluster, Colorado State University Continuing Education, Spirae, and Siemens has been used to guide the hiring of faculty, program curriculum and education plan. This project develops faculty leaders with the intellectual capacity to inspire its students to become leaders that substantially contribute to the development and maintenance of Smart Grid infrastructure through topics such as: (1) Distributed energy systems modeling and control; (2) Energy and power conversion; (3) Simulation of electrical power distribution system that integrates significant quantities of renewable and distributed energy resources; (4) System dynamic modeling that considers end-user behavior, economics, security and regulatory frameworks; (5) Best practices for energy management IT control solutions for effective distributed energy integration (including security with the underlying physical power systems); (6) Experimental verification of effects of various arrangements of renewable generation, distributed generation and user load types along with conventional generation and transmission. Understanding the core technologies for enabling them to be used in an integrated fashion within a distribution network remains is a benefit to the future energy paradigm and future and present energy engineers.

Lawrence Livermore National Laboratory Annual Report 2006  

SciTech Connect

For the Laboratory and staff, 2006 was a year of outstanding achievements. As our many accomplishments in this annual report illustrate, the Laboratory's focus on important problems that affect our nation's security and our researchers breakthroughs in science and technology have led to major successes. As a national laboratory that is part of the Department of Energy's National Nuclear Security Administration (DOE/NNSA), Livermore is a key contributor to the Stockpile Stewardship Program for maintaining the safety, security, and reliability of the nation's nuclear weapons stockpile. The program has been highly successful, and our annual report features some of the Laboratory's significant stockpile stewardship accomplishments in 2006. A notable example is a long-term study with Los Alamos National Laboratory, which found that weapon pit performance will not sharply degrade from the aging effects on plutonium. The conclusion was based on a wide range of nonnuclear experiments, detailed simulations, theoretical advances, and thorough analyses of the results of past nuclear tests. The study was a superb scientific effort. The continuing success of stockpile stewardship enabled NNSA in 2006 to lay out Complex 2030, a vision for a transformed nuclear weapons complex that is more responsive, cost efficient, and highly secure. One of the ways our Laboratory will help lead this transformation is through the design and development of reliable replacement warheads (RRWs). Compared to current designs, these warheads would have enhanced performance margins and security features and would be less costly to manufacture and maintain in a smaller, modernized production complex. In early 2007, NNSA selected Lawrence Livermore and Sandia National Laboratories-California to develop ''RRW-1'' for the U.S. Navy. Design efforts for the RRW, the plutonium aging work, and many other stockpile stewardship accomplishments rely on computer simulations performed on NNSA's Advanced Simulation and Computing (ASC) Program supercomputers at Livermore. ASC Purple and BlueGene/L, the world's fastest computer, together provide nearly a half petaflop (500 trillion operations per second) of computer power for use by the three NNSA national laboratories. Livermore-led teams were awarded the Gordon Bell Prize for Peak Performance in both 2005 and 2006. The winning simulations, run on BlueGene/L, investigated the properties of materials at the length and time scales of atomic interactions. The computing power that makes possible such detailed simulations provides unprecedented opportunities for scientific discovery. Laboratory scientists are meeting the extraordinary challenge of creating experimental capabilities to match the resolution of supercomputer simulations. Working with a wide range of collaborators, we are developing experimental tools that gather better data at the nanometer and subnanosecond scales. Applications range from imaging biomolecules to studying matter at extreme conditions of pressure and temperature. The premier high-energy-density experimental physics facility in the world will be the National Ignition Facility (NIF) when construction is completed in 2009. We are leading the national effort to perform the first fusion ignition experiments using NIF's 192-beam laser and prepare to explore some of the remaining important issues in weapons physics. With scientific colleagues from throughout the nation, we are also designing revolutionary experiments on NIF to advance the fields of astrophysics, planetary physics, and materials science. Mission-directed, multidisciplinary science and technology at Livermore is also focused on reducing the threat posed by the proliferation of weapons of mass destruction as well as their acquisition and use by terrorists. The Laboratory helps this important national effort by providing its unique expertise, integration analyses, and operational support to the Department of Homeland Security. For this vital facet of the Laboratory's national security mission, we are developing advanced technologies, such as

Challenges in small screening laboratories: implementing an on-demand laboratory information management system.  

PubMed

The Miami Project to Cure Paralysis, part of the University of Miami Miller School of Medicine, includes a laboratory devoted to High Content Analysis (HCA) of neurons. The goal of the laboratory is to uncover signaling pathways, genes, compounds, or drugs that can be used to promote nerve growth. HCA permits the quantification of neuronal morphology, including the lengths and numbers of axons. HCA of various libraries on primary neurons requires a team-based approach, a variety of process steps and complex manipulations of cells and libraries to obtain meaningful results. HCA itself produces vast amounts of information including images, well-based data and cell-based phenotypic measures. Documenting and integrating the experimental workflows, library data and extensive experimental results is challenging. For academic laboratories generating large data sets from experiments involving thousands of perturbagens, a Laboratory Information Management System (LIMS) is the data tracking solution of choice. With both productivity and efficiency as driving rationales, the Miami Project has equipped its HCA laboratory with an On Demand or Software As A Service (SaaS) LIMS to ensure the quality of its experiments and workflows. The article discusses how the system was selected and integrated into the laboratory. The advantages of a SaaS based LIMS over a client-server based system are described. PMID:21631415

Time complexity and gate complexity  

SciTech Connect

We formulate and investigate the simplest version of time-optimal quantum computation theory (TO-QCT), where the computation time is defined by the physical one and the Hamiltonian contains only one- and two-qubit interactions. This version of TO-QCT is also considered as optimality by sub-Riemannian geodesic length. The work has two aims: One is to develop a TO-QCT itself based on a physically natural concept of time, and the other is to pursue the possibility of using TO-QCT as a tool to estimate the complexity in conventional gate-optimal quantum computation theory (GO-QCT). In particular, we investigate to what extent is true the following statement: Time complexity is polynomial in the number of qubits if and only if gate complexity is also. In the analysis, we relate TO-QCT and optimal control theory (OCT) through fidelity-optimal computation theory (FO-QCT); FO-QCT is equivalent to TO-QCT in the limit of unit optimal fidelity, while it is formally similar to OCT. We then develop an efficient numerical scheme for FO-QCT by modifying Krotov's method in OCT, which has a monotonic convergence property. We implemented the scheme and obtained solutions of FO-QCT and of TO-QCT for the quantum Fourier transform and a unitary operator that does not have an apparent symmetry. The former has a polynomial gate complexity and the latter is expected to have an exponential one which is based on the fact that a series of generic unitary operators has an exponential gate complexity. The time complexity for the former is found to be linear in the number of qubits, which is understood naturally by the existence of an upper bound. The time complexity for the latter is exponential in the number of qubits. Thus, both the targets seem to be examples satisfyng the preceding statement. The typical characteristics of the optimal Hamiltonians are symmetry under time reversal and constancy of one-qubit operation, which are mathematically shown to hold in fairly general situations.

Managing Complexity  

SciTech Connect

Physical analogs have shown considerable promise for understanding the behavior of complex adaptive systems, including macroeconomics, biological systems, social networks, and electric power markets. Many of todays most challenging technical and policy questions can be reduced to a distributed economic control problem. Indeed, economically-based control of large-scale systems is founded on the conjecture that the price-based regulation (e.g., auctions, markets) results in an optimal allocation of resources and emergent optimal system control. This paper explores the state of the art in the use physical analogs for understanding the behavior of some econophysical systems and to deriving stable and robust control strategies for them. In particular we review and discussion applications of some analytic methods based on the thermodynamic metaphor according to which the interplay between system entropy and conservation laws gives rise to intuitive and governing global properties of complex systems that cannot be otherwise understood.

Laboratory Needs for Interstellar Ice Studies  

NASA Astrophysics Data System (ADS)

A large fraction of the molecules in dense interstellar and circumstellar environments is stored in icy grain mantles. The mantles are formed by a complex interplay between chemical and physical processes. Key questions on the accretion and desorption processes and the chemistry on the grain surfaces and within the icy mantles can only be answered by laboratory experiments. Recent infrared (2-30 micron) spectroscopic surveys of large samples of Young Stellar Objects (YSOs) and background stars tracing quiescent cloud material have shown that the ice band profiles and depths vary considerably as a function of environment. Using laboratory spectra in the identification process, it is clear that a rather complex mixture of simple species (CH3OH, CO2, H2O, CO) exists even in the quiescent cloud phase. Variations of the local physical conditions (CO freeze out) and time scales (CH3OH formation) appear to be key factors in the observed variations. Sublimation and thermal processing dominate as YSOs heat their environments. The identification of several ice absorption features is still disputed. I will outline laboratory work (e.g., on salts, PAHs, and aliphatic hydrocarbons) needed to further constrain the ice band identification as well as the thermal and chemical history of the carriers. Such experiments will also be essential to interpret future high spectral resolution SOFIA and JWST observations.

Omics in laboratory medicine.

Abstract In the last years, molecular diagnosis of human genetic diseases has greatly improved thanks to the knowledge of more than 7,000 disease genes (genomics). However, the study of such diseases revealed the very complex relationships between the phenotype of each disease and the molecular alterations responsible. The analysis of proteins (proteomics) revealed that most proteins are subjected to post-translational changes or to alternative splicing; the study of gene expression identified a series of mechanisms that modulate gene expression (epigenomics) which include microRNA regulation, histone acetylation and gene methylation. The alteration of all these mechanisms may contribute to the pathogenesis or to the phenotypic expression of most human genetic diseases. Molecular analysis became more and more complex, but "omics" studies revealed that each single individual is "unique". PMID:24059545

Value of Laboratory Experiments for Code Validations  

SciTech Connect

Numerical codes have become indispensable for designing underground structures and interpretating the behavior of geologic systems. Because of the complexities of geologic systems, however, code calculations often are associated with large quantitative uncertainties. This papers presents three examples to demonstrate the value of laboratory(or bench scale) experiments to evaluate the predictive capabilities of such codes with five major conclusions: Laboratory or bench-scale experiments are a very cost-effective, controlled means of evaluating and validating numerical codes, not instead of but before or at least concurrent with the implementation of in situ studies. The design of good laboratory validation tests must identifj what aspects of a code are to be scrutinized in order to optimize the size, geometry, boundary conditions, and duration of the experiments. The design of good and sometimes difficult numerical analyses and sensitivity studies. Laboratory validation tests must involve: Good validation experiments will generate independent data sets to identify the combined effect of constitutive models, model generalizations, material parameters, and numerical algorithms. Successfid validations of numerical codes mandate a close collaboration between experimentalists and analysts drawing from the full gamut of observations, measurements, and mathematical results.

Using 1H, 13C and 15N multidimensional NMR we have investigated laboratory plasma tholins and EUV generated photochemical solids for common structural motifs. These common structures largely determine the potential chemistry of these materials. As stimulants for Titan organic haze aerosols, these studies yield valuable information regarding the complex organic solids which reside on Titan's surface and potentially reacted with periodic liquid phase aqueous materials. Such information is necessary for intelligent design of future surface mission analytical instrumentation and also provides insights into the prebiotic potential on Titan. The results will be discussed in the context of our earlier work regarding the production of haze aerosols under ionospheric simulations at the Advanced Light Source as well as hydrolytic kinetic studies of laboratory tholins.

Laboratory high-energy astrophysics on lasers  

SciTech Connect

The tremendous range of temperatures and densities spanned by astrophysical plasmas has significant overlap with conditions attainable using high-power laser facilities. These facilities provide an opportunity to create, control, and characterize plasmas in the laboratory that mirror conditions in some of the most important cosmological systems. Moreover, laboratory experiments can enhance astrophysical understanding by focusing on and isolating important physical processes, without necessarily reproducing the exact conditions of the integral system. Basic study of radiative properties, transport phenomena, thermodynamic response and hydrodynamic evolution in plasmas under properly scaled conditions leads both directly and indirectly to improved models of complex astrophysical systems. In this paper, we will discuss opportunities for current and planned highpower lasers to contribute to the study of high-energy astrophysics.

Laboratory facilities are complex, technically sophisticated, and mechanically intensive structures that are expensive to build and to maintain. Hundreds of decisions must be made before and during new construction or renovation that will determine how successfully the facility will function when completed and how successfully it can be maintained once put into service. This book provides guidance on effective approaches for building laboratory facilities in the chemical and biochemical sciences. It contains both basic and laboratory-specific information addressed to the user community-the scientists and administrators who contract with design and construction experts. The book will also be important to the design and construction communities-the architects, laboratory designers, and engineers who will design the facility and the construction personnel who will build it-to help them communicate with the scientific community for whom they build laboratory facilities.

Carney complex.  

PubMed

Carney complex is a rare, dominantly inherited multiple endocrine neoplasia syndrome, affecting endocrine glands as the adrenal cortex (causing Cushing's syndrome), the pituitary and the thyroid. It is associated with many other nonendocrine tumors, including cardiac myxomas, testicular tumors, melanotic schwannoma, breast myxomatosis, and abnormal pigmentation (lentiginosis) or myxomas of the skin. The gene located on the CNC1 locus was identified 12 years ago as the regulatory subunit 1A (R1A) of the protein kinase A (PRKAR1A) located at 17q22-24. Inactivating heterozygous germline mutations of PRKAR1A are observed in about two thirds of Carney complex patients with some genotype-phenotype correlation useful for follow-up and prognosis. More rarely, mutations of phosphodiesterase genes have been reported in patients presenting mainly with Cushing's syndrome. In vitro and in vivo studies help to understand how R1A inactivation leads to tumorigenesis. PRKAR1A appears to be a relatively weak tumorigenic signal which can cooperate with other signaling pathways and tumor suppressors. PMID:23652670

This document summarizes the results of investigations into the rheological properties of alternate fuel mixtures, such as coal-oil mixtures, coal-water mixtures, and coal-alcohol mixtures. Primary emphasis in this paper is placed on the procedures and techniques used to evaluate alternate slurry fuels in the rheology laboratory at PETC through the spring of 1983. Sophisticated, bench-scale equipment was used to examine viscometric properties and to make settling velocity measurements. Examples of the data developed during this program are given to support the choice of measurement procedures and test conditions. Furthermore, a brief discussion of the applicability of various mathematical models for settling characteristics and rheological properties are included. Areas in which additional development of techniques is required are discussed. 25 references, 21 figures, 7 tables.

Laboratory Astrophysics of Dust  

NASA Astrophysics Data System (ADS)

Infrared spectroscopy is the best astronomical tool for studying the composition of cosmic dust. Thanks to the Herschel satellite, dust properties from the FIR to mm wavelength range will be sampled in different astrophysical environments. In the laboratory, the study of the temperature and structural dependence of FIR absorption of cosmic dust analogs including agglomeration is essential to interpret observational spectra. For crystalline materials, FIR single phonon bands are temperature dependent due to the anharmonicity of the vibrational potentials. This strong temperature dependence of the FIR bands' positions can be used as a thermometer of the dust temperature. In amorphous material, the FIR absorption is dominated by disorder-induced single phonon processes and in the submillimeter and millimeter range by highly temperature-dependent low energy processes, e.g. tunneling transitions in two-level systems. The effect of these processes on the FIR absorptivity in amorphous silicates will be demonstrated.

Laboratory Dipole Plasma Physics  

NASA Astrophysics Data System (ADS)

Modern laboratory studies of plasma confined by a strong dipole magnet originated twenty years ago when it was learned that planetary magnetospheres have centrally-peaked plasma pressure profiles that form naturally when solar wind drives plasma circulation and heating. Unlike other internal rings devices, like spherators and octupoles, the magnetic flux tubes of the dipole field expand rapidly with radius. Unlike plasma confinement devices that obtain stability from magnetic shear and average good curvature, like tokamaks and levitrons, the dipole-confined plasma obtains stability from plasma compressibility. These two geometric characteristics of the dipole field have profound consequences: (i) plasma can be stable with local beta exceeding unity, (ii) fluctuations can drive either heat or particles inward to create stationary profiles that are strongly peaked, and (iii) the confinement of particles and energy can decouple. During the past decade, several laboratory dipole experiments and modeling efforts have lead to new understanding of interchange, centrifugal and entropy modes, nonlinear gyrokinetics, and plasma transport. Two devices, the LDX experiment at MIT and RT-1 at the University of Tokyo, operate with levitated superconducting dipole magnets. With a levitated dipole, not only is very high-beta plasma confined in steady state but, also, levitation produces high-temperature at low input power and demonstrates that toroidal magnetic confinement of plasma does not require a toroidal field. Modeling has explained many of the processes operative in these experiments, including the observation of a strong inward particle pinch. Turbulent low-frequency fluctuations in dipole confined plasma cause adiabatic transport and form a fundamental linkage between the radial variation of flux-tube volume and the centrally peaked density and pressure profiles.

BNL Sources Development Laboratory  

SciTech Connect

The NSLS has a long-standing interest in providing the best possible synchrotron radiation sources for its user community, and hence, has recently established the Source Development Laboratory (SDL) to pursue research into fourth generation synchrotron radiation sources. A major element of the program includes development of a high peak power FEL meant to operate in the vacuum ultraviolet. The objective of the program is to develop the source, and experimental technology together to provide the greatest impact on UV science. The accelerator under construction for the SDL consists of a high brightness RF photocathode electron gun followed by a 230 MeV short pulse linac incorporating a magnetic chicane for pulse compression. The gun drive laser is a wide bandwidth Ti: Sapphire regenerative amplifier capable of pulse shaping which will be used to study non- linear emittance compensation. Using the compressor, 1 nC bunches with a length as small as 50 {mu}m sigma (2 kA peak current) are available for experiments. In this paper we briefly describe the facility and detail our plans for utilizing the 10 m long NISUS wiggler to carry out single pass FEL experiments. These include a 1 {mu}m SASE demonstration, a seeded beam demonstration at 300 nm, and a High Gain Harmonic Generation experiment at 200 mn. The application of chirped pulse amplification to this type of FEL will also be discussed.

Laboratory diagnosis of SARS.  

PubMed Central

The emergence of new viral infections of man requires the development of robust diagnostic tests that can be applied in the differential diagnosis of acute illness, or to determine past exposure, so as to establish the true burden of disease. Since the recognition in April 2003 of the severe acute respiratory syndrome coronavirus (SARS-CoV) as the causative agent of severe acute respiratory syndrome (SARS), enormous efforts have been applied to develop molecular and serological tests for SARS which can assist rapid detection of cases, accurate diagnosis of illness and the application of control measures. International progress in the laboratory diagnosis of SARS-CoV infection during acute illness has led to internationally agreed World Health Organization criteria for the confirmation of SARS. Developments in the dissection of the human immune response to SARS indicate that serological tests on convalescent sera are essential to confirm SARS infection, given the sub-optimal predictive value of molecular detection tests performed during acute SARS illness.

Titan's ion chemistry: a laboratory perspective.  

PubMed

Some of the most interesting objects in the solar system are those bodies that have significant atmospheres. The discovery that Titan, Saturn's largest satellite, has a substantial nitrogen-based atmosphere makes it a prime extraterrestrial object of interest. The advent of the Cassini orbiter spacecraft program that is able to observe and sample Titan's ionosphere adds greatly to this interest. We report here a summary of some of the efforts that have been made in the laboratory to understand the processes responsible for chemical processing of the primary ions formed in Titan's ionosphere, into the ions observed by in situ sampling. The presence of significant hydrocarbons and the colder temperatures of Titan's ionosphere lead to a much greater complexity in the ion chemistry of Titan than is apparent in the ion chemistry of Earth. A review of all the ion-molecule chemistry investigated in laboratory studies relevant to Titan is included as a table. The complexity of some of the hydrocarbon ion structures formed in just three reactive ion-molecule sequences from the primary ions has required a new experimental methodology which is discussed.

Bridging Laboratory and Astronomy - Introduction  

NASA Astrophysics Data System (ADS)

The objectives of this 3-day Meeting-in-a-Meeting (MiM) are to expand on the series of meetings that was successfully initiated by the Working Group on Laboratory Astrophysics (WGLA) at last year's summer meeting to promote and increase the interaction between the laboratory astrophysics and the astronomy/planetary communities. This Meeting-in-a-Meeting is devoted to the interplay between laboratory astrophysics and IR, FIR and Submm astronomy. The sessions will discuss current and future missions and facilities that operate in this domain and their laboratory astrophysics needs. Astronomy is an observational science detecting photons generated by atomic, molecular, and solid-state physics and chemistry. The astrophysically motivated studies, which consist of both laboratory experiments and theoretical calculations, are collectively known as laboratory astrophysics. This Meeting-in-a-Meeting will consist of six sessions that will discuss the nature and evolution of molecules, dust and ices from stellar and planetary formation regions to circumstellar, planetary nebulae and diffuse ISM environments to comets and planets. The sessions map the sub areas of laboratory astrophysics in the IR, FIR and Submm domains and cover the study of molecules, dust and ices. Each session will include talks focusing on major mission projects and key data needs, related experimental and theoretical work, all illustrating the important role of laboratory astrophysics in support of current and future missions and facilities. An associated poster session on astronomical observations and laboratory astrophysics of molecules, dust and ices runs for 3 days.

Robotics in the clinical laboratory.  

PubMed

We are beginning to see the potential of robotics in the clinical laboratory through integration with automated analyzers and computer systems. However, there is a need for training programs that will prepare technologists to design and implement robotic systems for clinical laboratories. What will the robot laboratory of the future look like? We will see hospital laboratories begin to be located some distance away from the main facility because the labor component of staffing satellite laboratories will have been greatly reduced. Instrument manufacturers will see the need for analyzers that are robot-friendly and allow for simplified interfacing, both electronic and mechanical. Robots will become more versatile even to the point of performing complete instrument repair. Laboratories will be equipped with many task-oriented robotic stations, including, for example, accessioning and processing robots that prepare samples for transport by robotic carts. Analysis will be performed by a combination of robot and dedicated analyzer. Laboratory results will be reviewed by algorithms in the larger laboratory computer, which will alert the laboratory worker to unusual results. A large variety of analyses will be available to the patient with rapid turnaround. The end result will be more efficient health care delivery at reduced cost. PMID:3061728

The Hubble Space Telescope and Laboratory Astrophysics  

NASA Astrophysics Data System (ADS)

The Hubble Space Telescope (HST) continues to push the limits on world-class astrophysics. Cameras including the Advanced Camera for Surveys and the new panchromatic Wide Field Camera 3, which was installed on the recent successful servicing mission SM4, offer imaging from near-infrared through ultra- violet wavelengths. Spectroscopic studies of sources from black holes to exoplanet atmospheres are making great advances through the versatile use of STIS, the Space Telescope Imaging Spectrograph. The new Cosmic Origins Spectrograph, also installed last year, is the most sensitive UV spectrograph to y in space and is uniquely suited to address particular scientific questions on galaxy halos, the intergalactic medium, and the cosmic web. With these outstanding capabilities on HST come complex needs for laboratory astrophysics support including atomic and line identification data. This paper provides an overview of Hubble's current capabilities and the scientific programs and goals that particularly benefit from the studies of laboratory astrophysics. With no current plans for further servicing of Hubble (and thus limited further observations), and no future major optical/UV space observatory currently planned for at least the next decade, it is essential to maximize the critical laboratory astrophysics support needed for Hubble observations in the near-term.

[Carney complex].  

PubMed

Carney complex (CNC) is an autosomal dominantly inherited syndrome characterized by spotty skin pigmentation, cardiac and cutaneous myxoma, and endocrine overactivity. Skin pigmentation includes lentigines and blue nevi. Myxomas may occur in breast, skin and heart. Cardiac myxomas may be multiple and occur in any cardiac chamber, and are more prone to recurrence. The most common endocrine gland manifestation is an ACTH-independent Cushing's syndrome due to primary pigmented nodular adrenocortical disease (PPNAD). PPNAD may occur isolated, with no other signs of CNC. Pituitary and thyroid glands and gonads are also involved. The PRKAR1A gene, located in 17 q22-24, encodes type 1A regulatory subunit of protein kinase A. Inactivating germline mutations of this gene are found in 70% of patients with CNC. PRKAR1A is a key component of the c-AMP signaling pathway that has been implicated in endocrine tumorigenesis. Many different mutations have been reported in the PRKAR1A gene. In almost all cases the sequence change was predicted to lead to a premature stop codon and the resultant mutant mRNA was subject to nonsense-mediated mRNA decay. There is no clear genotype-phenotype correlation in patients with CNC. Genetic analysis should be performed in all CNC index cases. All affected patients should be monitored for clinical signs of CNC at least once a year. Genetic diagnosis allows for more effective preparation of more appropriate and effective therapeutic strategies and genetic counseling for patients and gene carriers, and to avoid unnecessary tests to relatives not carrying the gene.

Testing containment of laboratory hoods  

SciTech Connect

Laboratory fume hoods often do not adequately provide protection to a chemist or technician at the hood. The reason for failure of the hoods to perform adequately are varied and, in many instances, difficult to determine. In some cases, the laboratory hood manufacturer has provided equipment that does not reflect the state of art in controlling laboratory exposures. In other cases, the architect or engineer has disregarded the function of the hood thus the design of the installation is faulty and the hood will not work. The contractor may have installed the system so poorly that it will not adequately function. Finally, the chemist or technician may misuse the hood, causing poor performance. This paper considers a method of evaluating the performance of laboratory fume hoods. Using the method, the paper examines several instances where the laboratory fume hood performed inadequately, quantifies the performance and identifies the cause of poor performance.

Accidental fires in clinical laboratories.  

PubMed

The National Fire Protection Association, Quincy, Mass, estimates that 169 fires have occurred annually in health care, medical, and chemical laboratories. On the average, there are 13 civilian injuries and $1.5 million per year in direct property damage. Most fires in which the cause or ignition source can be identified originate in malfunctioning electrical equipment (41.6%) or in the facility's electrical distribution system (14.7%). The prevalence of fire safety deficiencies was measured in the College of American Pathologists Laboratory Accreditation Program. Of the 1732 inspected laboratories, 5.5% lacked records of electrical receptacle polarity and ground checks in the preceding year. Of these inspected laboratories, 4.7% had no or incomplete documentation of electrical safety checks on laboratory instruments. There was no evidence of quarterly fire exit drills in 9% of the laboratories. Deficiencies were also found in precautionary labeling (6.8%), in periodic review of safe work practices (4.2%), in the use of safety cans (3.7%), and in venting of flammable liquid storage areas (2.8%). Fire preparedness would be improved if all clinical laboratories had smoke detectors and automatic fire-extinguishing systems. In-service training courses in fire safety should be targeted to the needs of specific service areas. PMID:8250687

Clinical laboratory accreditation in India.  

PubMed

Test results from clinical laboratories must ensure accuracy, as these are crucial in several areas of health care. It is necessary that the laboratory implements quality assurance to achieve this goal. The implementation of quality should be audited by independent bodies,referred to as accreditation bodies. Accreditation is a third-party attestation by an authoritative body, which certifies that the applicant laboratory meets quality requirements of accreditation body and has demonstrated its competence to carry out specific tasks. Although in most of the countries,accreditation is mandatory, in India it is voluntary. The quality requirements are described in standards developed by many accreditation organizations. The internationally acceptable standard for clinical laboratories is ISO15189, which is based on ISO/IEC standard 17025. The accreditation body in India is the National Accreditation Board for Testing and Calibration Laboratories, which has signed Mutual Recognition Agreement with the regional cooperation the Asia Pacific Laboratory Accreditation Cooperation and with the apex cooperation the International Laboratory Accreditation Cooperation.

Preservice laboratory education strengthening enhances sustainable laboratory workforce in Ethiopia  

PubMed Central

Background There is a severe healthcare workforce shortage in sub Saharan Africa, which threatens achieving the Millennium Development Goals and attaining an AIDS-free generation. The strength of a healthcare system depends on the skills, competencies, values and availability of its workforce. A well-trained and competent laboratory technologist ensures accurate and reliable results for use in prevention, diagnosis, care and treatment of diseases. Methods An assessment of existing preservice education of five medical laboratory schools, followed by remedial intervention and monitoring was conducted. The remedial interventions included 1) standardizing curriculum and implementation; 2) training faculty staff on pedagogical methods and quality management systems; 3) providing teaching materials; and 4) procuring equipment for teaching laboratories to provide practical skills to complement didactic education. Results A total of 2,230 undergraduate students from the five universities benefitted from the standardized curriculum. University of Gondar accounted for 252 of 2,230 (11.3%) of the students, Addis Ababa University for 663 (29.7%), Jimma University for 649 (29.1%), Haramaya University for 429 (19.2%) and Hawassa University for 237 (10.6%) of the students. Together the universities graduated 388 and 312 laboratory technologists in 2010/2011 and 2011/2012 academic year, respectively. Practical hands-on training and experience with well-equipped laboratories enhanced and ensured skilled, confident and competent laboratory technologists upon graduation. Conclusions Strengthening preservice laboratory education is feasible in resource-limited settings, and emphasizing its merits (ample local capacity, country ownership and sustainability) provides a valuable source of competent laboratory technologists to relieve an overstretched healthcare system.

E-laboratories : agent-based modeling of electricity markets.  

SciTech Connect

Electricity markets are complex adaptive systems that operate under a wide range of rules that span a variety of time scales. These rules are imposed both from above by society and below by physics. Many electricity markets are undergoing or are about to undergo a transition from centrally regulated systems to decentralized markets. Furthermore, several electricity markets have recently undergone this transition with extremely unsatisfactory results, most notably in California. These high stakes transitions require the introduction of largely untested regulatory structures. Suitable laboratories that can be used to test regulatory structures before they are applied to real systems are needed. Agent-based models can provide such electronic laboratories or ''e-laboratories.'' To better understand the requirements of an electricity market e-laboratory, a live electricity market simulation was created. This experience helped to shape the development of the Electricity Market Complex Adaptive Systems (EMCAS) model. To explore EMCAS' potential as an e-laboratory, several variations of the live simulation were created. These variations probed the possible effects of changing power plant outages and price setting rules on electricity market prices.

The field of clinical laboratory tests is facing an increase in the number of test items as well as a corresponding diversification due to the demands of medical institutions as well as improvements in analytical techniques. To respond to this situation, medical institutions have been promoting systematization of their testing procedures; information exchange among the institutions has likewise expanded with the use of media such as on-line systems and internet. Standardization of interfaces has been proposed to secure a common framework compatible with different types of information. Some embodiments in this country includes; (1) Interface Standards on Clinical Laboratory Information For information exchange, the format and reporting comments used in the media systems were standardized under the sponsorship of The Medical Information System Development Center, with a publication issued on 1993. (2) Standardization of Laboratory Test Code Standardization of codes for information exchange has been established under the sponsorship of The Japan Society of Clinical Pathology (Laboratory Test Coding Committee), through the systematization of laboratory test code used in media systems. A publication entitled "Classification & Coding for Clinical Laboratory Tests (8th edition in 1992, 9th edition in 1994 and supplement in 1996)" has been issued. The system for "Classification & Coding for Clinical Laboratory Tests" is divided into 5 components; (1) analyte code, (2) identification code, (3) specimen code, (4) methodology code, and (5) data classification code. The Laboratory test codes are precisely classified by "(1) analyte code", and then are identified by combination of additional codes such as specimen and methodology codes.

If it is properly supported by academic centers, industry, and funding agencies, the virtual national laboratory could succeed in advancing and maintaining major improvements in clinical trial conduct and efficiency.

DISMANTLING OF THE FUEL CELL LABORATORY AT RESEARCH CENTRE JUELICH  

SciTech Connect

The fuel cell laboratory was constructed in three phases and taken into operation in the years 1962 to 1966. The last experimental work was carried out in 1996. After all cell internals had been disassembled, the fuel cell laboratory was transferred to shutdown operation in 1997. Three cell complexes, which differed, in particular, by the type of shielding (lead, cast steel, concrete), were available until then for activities at nuclear components. After approval by the regulatory authority, the actual dismantling of the fuel cell laboratory started in March 2000. The BZ I laboratory area consisted of 7 cells with lead shieldings of 100 to 250 mm thickness. This area was dismantled from April to September 2000. Among other things, approx. 30,000 lead bricks with a total weight of approx. 300 Mg were dismantled and disposed of. The BZ III laboratory area essentially consisted of cells with concrete shieldings of 1200 to 1400 mm thickness. The dismantling of this area started in the fir st half of 2001 and was completed in November 2002. Among other things, approx. 900 Mg of concrete was dismantled and disposed of. Since more than 90 % of the dismantled materials was measurable for clearance, various clearance measurement devices were used during dismantling. The BZ II laboratory area essentially consists of cells with cast steel shieldings of 400 to 460 mm thickness. In September 2002 it was decided to continue using this laboratory area for future tasks. The dismantling of the fuel cell laboratory was thus completed. After appropriate refurbishment, the fuel cell laboratory will probably take up operation again in late 2003.

Teaching Writing Skills in the Undergraduate Laboratory  

NASA Astrophysics Data System (ADS)

Stanford University's Writing in the Major program (WIM) requires every undergraduate degree program to include a writing course specific to its field of study. In the physics department's WIM course, undergraduates learn writing skills by composing laboratory reports in the form of journal articles. While studying such topics as scintillation and population inversion, students also practice techniques for communicating the physics more effectively. Students learn how to select a thesis, organize a complex argument, write concisely, aim their content at the proper audience, prove their assertions, and revise a finished draft. Through clearer writing, students reach a clearer understanding of the physics, and the improvements in both understanding and communication stay with the students through later courses and into their graduate studies. Teaching assistants for the course also notice a marked improvement in their own writing skills.

Biologically Inspired Phosphino Platinum Complexes  

SciTech Connect

Platinum complexes containing phosphino amino acid and amino acid ester ligands, built upon the PPhNR2 platform, have been synthesized and characterized (PPhNR2= [1,3-diaza]-5-phenyl phosphacyclohexane, R=glycine or glycine ester). These complexes were characterized by 31P, 13C, 1H, 195Pt NMR spectroscopy and mass spectrometry. The X-ray crystal structure of one of the complexes, [PtCl2(PPhNGlyester 2)2], is also reported. These biologically inspired ligands have potential use in homogeneous catalysis, with special applications in chiral chemistry and water soluble chemistry. These complexes also provide a foundation upon which larger peptides can be attached, to allow the introduction of enzyme-like features onto small molecule catalysts. This work was supported by the US Department of Energy, Office of Basic Energy Sciences, Division of Chemical Sciences, Geosciences & Biosciences. Pacific Northwest National Laboratory is operated by Battelle for the US Department of Energy.

Laboratory medicine and sports: between Scylla and Charybdis.  

PubMed

Laboratory medicine is complex and contributes to the diagnosis, therapeutic monitoring and follow-up of acquired and inherited human disorders. The regular practice of physical exercise provides important benefits in heath and disease and sports medicine is thereby receiving growing focus from almost each and every clinical discipline, including laboratory medicine. Sport-laboratory medicine is a relatively innovative branch of laboratory science, which can provide valuable contributions to the diagnosis and follow-up of athletic injuries, and which is acquiring a growing clinical significance to support biomechanics and identify novel genomics and "exercisenomics" patterns that can help identify specific athlete's tendency towards certain types of sport traumas and injuries. Laboratory medicine can also provide sport physicians and coaches with valuable clues about personal inclination towards a certain sport, health status, fitness and nutritional deficiencies of professional, elite and recreational athletes in order to enable a better and earlier prediction of sport injuries, overreaching and overtraining. Finally, the wide armamentarium of laboratory tests represents the milestone for identifying cheating athletes in the strenuous fight against doping in sports. PMID:22868795

Managing Science: Management for R&D Laboratories  

NASA Astrophysics Data System (ADS)

A unique "how-to" manual for the management of scientific laboratories This book presents a complete set of tools for the management of research and development laboratories and projects. With an emphasis on knowledge rather than profit as a measure of output and performance, the authors apply standard management principles and techniques to the needs of high-flux, open-ended, separately funded science and technology enterprises. They also propose the novel idea that failure, and incipient failure, is an important measure of an organization's potential. From the management of complex, round-the-clock, high-tech operations to strategies for long-term planning, Managing Science: Management for R&D Laboratories discusses how to build projects with the proper research and development, obtain and account for funding, and deal with rapidly changing technologies, facilities, and trends. The entire second part of the book is devoted to personnel issues and the impact of workplace behavior on the various functions of a knowledge-based organization. Drawing on four decades of involvement with the management of scientific laboratories, the authors thoroughly illustrate their philosophy with real-world examples from the physics field and provide tables and charts. Managers of scientific laboratories as well as scientists and engineers expecting to move into management will find Managing Science: Management for R&D Laboratories an invaluable practical guide.

Creating an Advanced Laboratory for K-16 Science Education at the Princeton Plasma Physics Laboratory  

NASA Astrophysics Data System (ADS)

An innovative laboratory dedicated to plasma science education at the pre-college and undergraduate level will be described. The Plasma Science Education Laboratory (PSEL) will be the first of its kind, a cutting-edge education facility and associated programs that bring the beauty and complexity of plasmas to a greatly expanded range of teachers and students who now rarely have the chance to study plasma physics in a hands-on manner. Crucial to the success of PSEL is an integrated teaching approach that has students at all levels learn physics in the same manner that a research scientist does physics. At the core of this method is a research-based experience (in the laboratory) woven together with the necessary theoretical basis (in the classroom) and the use of advanced computational tools with an emphasis on visualization of the underlying principles. The new activities will be supported by the creation of a group of Master Teachers to both develop and assist in the teaching of new workshops. A summer educational internship will be created to bring new master teachers in to assist in the various programs. These master teachers will be veterans of previous workshops and, thus, well versed in basic plasma physics theory and experimentation.

Defense programs industrial partnerships at Los Alamos National Laboratory  

SciTech Connect

The US Department of Energy`s Defense Programs face unprecedented challenges of stewardship for an aging nuclear stockpile, cessation of nuclear testing, reduced federal budgets, and a smaller manufacturing complex. Partnerships with industry are essential in developing technology, modernizing the manufacturing complex, and maintaining the safety and reliability of the nation`s nuclear capability. The past decade of federal support for industrial partnerships has promoted benefits to US industrial competitiveness. Recent shifts in government policy have re-emphasized the importance of industrial partnerships in accomplishing agency missions. Nevertheless, abundant opportunities exist for dual-benefit, mission-driven partnerships between the national laboratories and industry. Experience at Los Alamos National Laboratory with this transition is presented.

Virtual Laboratories and Virtual Worlds  

NASA Astrophysics Data System (ADS)

Since we cannot put stars in a laboratory, astrophysicists had to wait till the invention of computers before becoming laboratory scientists. For half a century now, we have been conducting experiments in our virtual laboratories. However, we ourselves have remained behind the keyboard, with the screen of the monitor separating us from the world we are simulating. Recently, 3D on-line technology, developed first for games but now deployed in virtual worlds like Second Life, is beginning to make it possible for astrophysicists to enter their virtual labs themselves, in virtual form as avatars. This has several advantages, from new possibilities to explore the results of the simulations to a shared presence in a virtual lab with remote collaborators on different continents. I will report my experiences with the use of Qwaq Forums, a virtual world developed by a new company (see http://www.qwaq.com).

Fixing the national laboratory system  

SciTech Connect

Over the past 20 years, there have been numerous studies of the Department of Energy (DOE) national laboratories. Having reviewed numerous recommendations of outsiders, the Department of Energy responds with a plan of action. Having reviewed these, we find that there is much merit in the criticisms and much good intention in the proposals to change the governance and focus of the laboratories. But we believe that the proposals either attack the wrong problems or are simply unlikely to succeed. We have developed instead what we believe is a comprehensive and practical strategy to manage the national laboratory system to achieve national goals and to make it once again an essential, cost-effective, and well-managed element of the nation`s R&D enterprise. We believe that this approach, unlike others tried over the past two decades, is demonstrably working and should be continued. This paper outlines these proposals.

Novel anticoagulants and laboratory testing.  

PubMed

The introduction of several oral direct anticoagulants within the past 2-3years has dramatically changed clinical practice and has also impacted on utilization and interpretation of coagulation laboratory testing. This article reviews the effects of the oral thrombin inhibitor, dabigatran, and the oral factor Xa inhibitors, rivaroxaban and apixaban, on screening and diagnostic coagulation tests, and describes methods for measuring the their anticoagulant activity in plasma. Currently, there are evidence gaps regarding the role of laboratory testing for surveillance and management of adverse events associated with these new anticoagulants which do not require routine therapeutic drug monitoring. This is a rapidly changing field, and coagulation laboratory experts have a major role in ensuring patients receive appropriate testing and accurate interpretations of results. PMID:23590653

Laboratory Experiments on Magnetic Reconnection  

NASA Astrophysics Data System (ADS)

Magnetic reconnection, a topological rearrangement of magnetic field lines, is one of the key self-organization processes in laboratory and astrophysical plasmas. This talk presents the fundamental physics of magnetic reconnection reviewing the recent significant progress in laboratory experiments. Sawtooth relaxation in a tokamak plasma, which represents a repetitive change of the electron temperature profile, provides a good example of magnetic reconnection. During the relaxation phase of the sawtooth, a rapid flattening of the electron temperature profile occurs and the pitch of field lines changes suddenly as the field lines break and rearrange themselves to form a new topological profile. In the reversed field pinch (RFP) and spheromak plasmas, a sudden re-arrangement of field lines in an inner flux surface can trigger another rearrangement in the outer flux surfaces, leading to a global magnetic relaxation event. Magnetic reconnection physics has been investigated in a variety of laboratory experiments dedicated for reconnection research. These laboratory experiments have made important contributions to recent advances in our understanding of magnetic reconnection. Significant findings are as follows: 1) The reconnection dynamics are determined both by local and global conditions, 2) The profiles of the reconnection layer and reconnection rate change drastically as the plasma's collisionality is reduced, 3) Two-fluid dynamics have been verified through experimental identification of both the ion and electron diffusion layers, 4) Electrostatic and electromagnetic fluctuations and their spatial profiles were measured in the reconnection layer of both laboratory and space plasmas with notable similarities, and 5) The reconnection rate increases significantly when the ratio of the electron mean free path to the scale length approaches unity. A new scaling of reconnection resistivity with respect to this ratio has been obtained from the laboratory results. The impact of this recently advanced understanding on research on space-terrestrial plasmas will be discussed.

Materials Characterization Laboratory (Fact Sheet)  

SciTech Connect

This fact sheet describes the purpose, lab specifications, applications scenarios, and information on how to partner with NREL's Materials Characterization Laboratory at the Energy Systems Integration Facility. The Materials Characterization Laboratory at NREL's Energy Systems Integration Facility (ESIF) research focus is the physical and photoelectrochemical characterization of novel materials. In this laboratory unknown samples are characterized by identifying and quantifying molecular species present through the implementation of a suite of analytical instrumentation and techniques. This leads to the ability to deconvolute decomposition routes and elucidate reaction mechanisms of materials through thermal and evolved gas analysis. This aids in the synthesis of next generation materials that are tailored to optimize stability and performance. These techniques and next generation materials will have many applications. One particular focus is the stable and conductive tetherable cations for use as membrane materials in anion exchange membrane fuel cells. Another is to understand the leachant contaminants derived from balance of plant materials used in proton exchange membrane fuel cell vehicles. Once identified and quantified, these organic and ionic species are dosed as contaminants into ex/in-situ fuel cell tests, to determine the effect on durability and performance. This laboratory also acts in support of fuel cell catalysis, manufacturing, and other related projects. The Materials Characterization Laboratory will cover multiple analytical operations, with the overall goal of troubleshooting synthetic materials or process streams to improve performance. Having novel evolved gas analysis and other analytical capabilities; this laboratory provides a viable location to analyze small batch samples, whereas setting up these types of capabilities and expertise would be cost and time prohibitive for most institutions. Experiments that can be performed include: (1) Evolved gas analysis; (2) Heterogeneous catalysis; (3) Trace level contaminants analysis; (4) Catalyst characterization; (5) Kinetics and stability; (6) Hyphenated techniques; and (7) Isotopic analysis for elucidating reaction mechanisms and decoupling chemical reactions.

Microsoft Academic Search

A least-mean-square (LMS) adaptive algorithm for complex signals is derived. The original Widrow-Hoff LMS algorithm is Wj+l= Wj+ 2?jXj. The complex form is shown to be Wj+1= Wj+ 2?jX-j, where the boldfaced terms represent complex (phasor) signals and the bar above Xjdesignates complex conjugate.

The Mycobacterium avium complex.  

PubMed Central

Mycobacterium avium complex (MAC) disease emerged early in the epidemic of AIDS as one of the common opportunistic infections afflicting human immunodeficiency virus-infected patients. However, only over the past few years has a consensus developed about its significance to the morbidity and mortality of AIDS. M. avium was well known to mycobacteriologists decades before AIDS, and the MAC was known to cause disease, albeit uncommon, in humans and animals. The early interest in the MAC provided a basis for an explosion of studies over the past 10 years largely in response to the role of the MAC in AIDS opportunistic infection. Molecular techniques have been applied to the epidemiology of MAC disease as well as to a better understanding of the genetics of antimicrobial resistance. The interaction of the MAC with the immune system is complex, and putative MAC virulence factors appear to have a direct effect on the components of cellular immunity, including the regulation of cytokine expression and function. There now is compelling evidence that disseminated MAC disease in humans contributes to both a decrease in the quality of life and survival. Disseminated disease most commonly develops late in the course of AIDS as the CD4 cells are depleted below a critical threshold, but new therapies for prophylaxis and treatment offer considerable promise. These new therapeutic modalities are likely to be useful in the treatment of other forms of MAC disease in patients without AIDS. The laboratory diagnosis of MAC disease has focused on the detection of mycobacteria in the blood and tissues, and although the existing methods are largely adequate, there is need for improvement. Indeed, the successful treatment of MAC disease clearly will require an early and rapid detection of the MAC in clinical specimens long before the establishment of the characteristic overwhelming infection of bone marrow, liver, spleen, and other tissue. Also, a standard method of susceptibility testing is of increasing interest and importance as new effective antimicrobial agents are identified and evaluated. Antimicrobial resistance has already emerged as an important problem, and methods for circumventing resistance that use combination therapies are now being studied. Images

Research Instrumentation Used in Education: Liquid Chromatography-Mass Spectrometry Experiences in Upper-Class Laboratory Settings  

NSDL National Science Digital Library

The purpose of this workshop was to explore the ramificationsof using complex, research-grade instrumentation inundergraduate science education. Our thesis is that the useof complicated instruments--meaning complex in theory,data interpretation, operation, and/or sample preparation--inundergraduate laboratory settings introduces unique pedagogicalelements. We identify and discuss those elementsbased on our experience in using such instrumentation, particularlyliquid chromatography with mass spectral detection,in an integrated laboratory.This is a chapter in the Innovative Laboratory Design section of the Course, Curriculum and Laboratory Improvement (CCLI) April 2004 conference proceedings published under the title Invention and Impact: Building Excellence in Undergraduate Science, Technology, Engineering and Mathematics (STEM) Education.

Federal laboratories for the 21st century  

SciTech Connect

Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

Laboratory voice data entry system.

We have assembled a system using a personal computer workstation equipped with standard office software, an audio system, speech recognition software and an inexpensive radio-based wireless microphone that permits laboratory workers to enter or modify data while performing other work. Speech recognition permits users to enter data while their hands are holding equipment or they are otherwise unable to operate a keyboard. The wireless microphone allows unencumbered movement around the laboratory without a "tether" that might interfere with equipment or experimental procedures. To evaluate the potential of voice data entry in a laboratory environment, we developed a prototype relational database that records the disposal of radionuclides and/or hazardous chemicals. Current regulations in our laboratory require that each such item being discarded must be inventoried and documents must be prepared that summarize the contents of each container used for disposal. Using voice commands, the user enters items into the database as each is discarded. Subsequently, the program prepares the required documentation. PMID:10631499

Computer vision and robotics laboratory  

SciTech Connect

Using computer vision to support real-time, intelligent robotic manipulation of objects, an australian laboratory is experimenting with a variety of equipment and algorithm combinations. The preliminary results shown in this article are indicative of the type of work supported in the laboratory. As in any laboratory situation, researchers are finding signs of encouragement as well as discovering some of the system's shortcomings as the exploration proceeds. On the positive side, it is becoming increasingly clear that combining range and color image data provides a rich data base for scene segmentation and that this is likely to support experiments in hand/eye manipulation with a fair degree of reliability. Further, it is fairly obvious that actually positioning the manipulator in the scene can permit a degree of feedback to enhance scene analysis and test interpretation hypotheses-something that cannot be provided by remote imaging and range scanning alone. On the negative side, however, it appears that special computing apparatus, including video stream and array image processing facilities, are going to be needed if relatively sophisticated, real-time hand/eye coordination is to become a reality. Knowing this, the laboratory is now aware of the direction it needs to move in. 34 references.

CBRN mobile laboratories in Italy  

NASA Astrophysics Data System (ADS)

The paper describes the experiences in Italy with the CBRN (Chemical Biological Radiological Nuclear) defense mobile laboratories. These laboratories were constructed by the Italian Army and the Italian Fire Brigades. The purpose of these mobile laboratories is to allow quick transport of the labs to the area of crisis in order to support emergency response in case of CBRN events. The differences between two alternative solutions will be developed in the paper. The first solution is when the lab is to be located in the "dangerous area" (this solution was chosen by the Italian Army) and the alternative approach is to place the mobile lab just outside the dangerous area (this approach was selected by the Italian Fire Brigades). One of the most important devices inside the lab is the isolator (also called "glove box") which allows safe ingress and handling of the "suspicious" samples from the external environment. The isolator has a special chamber for transfer of the sample from the outside. The pressure of the isolator is permanently kept below the air pressure inside the lab by means of one (or more) fan. The operators perform the sample preparations or part of the analysis by handling the sample with the gloves. The material flow inside the lab will be described depending on the kind of identification analysis to be done on the samples. Other devices installed on the mobile CBRN laboratories are: biohazard hood (UE regulation, containment level 2); autoclave; freezer; cleaning skid (tanks, pumps, etc.).

Complex regional pain syndrome.  

PubMed

As suggested by this article, considerable advances in clinical management and research have taken place during the past 20 years. Although mechanisms underlying the pain syndrome CRPS I and CRPS II remain far from one's understanding, glimpses of the pathophysiology are beginning to take shape. There is now strong evidence that these syndromes exemplify a complex neurologic disease involving the brain at several integrated levels. The changes that occur in CRPS I patients involve somatosensory, sympathetic, and somatomotor systems. The diagnostic criteria have helped to focus on aspects of these foregoing systems and whereas there is no specific laboratory test for CRPS, enough is now known about the pathophysiology to use the following tests: quantitative sensory testing (QST), autonomic testing that include quantitative sudomotor axon reflex test (QSART) for sweating abnormalities, the cold pressor test in conjunction with thermographic imaging to observe the vasoconstrictor response, and laser Doppler flowmetry to monitor background vasomotor control. Recognition of a motor disorder requires accurate documentation and may be a component of the diagnostic criteria in the future. Until a better understanding of mechanistic overtones that would help to put in place mechanism-based therapeutic strategies, current management is built around a rehabilitation model. For this to be successful, as described in the foregoing pages, different non-interventional and interventional modalities are applied in a time-restricted manner to facilitate those modalities that favor progress in the treatment algorithm. As has been described, it is important when using physiotherapeutic maneuvers to minimize joint movement in the affected region to reduce the mechanorecpetor barrage and its increase in perceived pain to encourage and maintain a patient's compliance with their rehabilitation. Finally, of greater significance is the understanding that sympatholysis per se is not a "diagnostic" test for CRPS, but rather a useful procedure that may facilitate treatment for pain that is sympathetically maintained.
