Standard Deviation for Small Samples  

ERIC Educational Resources Information Center

|Neater representations for variance are given for small sample sizes, especially for 3 and 4. With these representations, variance can be calculated without a calculator if sample sizes are small and observations are integers, and an upper bound for the standard deviation is immediate. Accessible proofs of lower and upper bounds are presented for…

Standard deviation, standard error. Which 'standard' should we use?  

PubMed

Standard deviation (SD) and standard error (SE) are quietly but extensively used in biomedical publications. These terms and notations are used as descriptive statistics (summarizing numerical data), and they are used as inferential statistics (estimating population parameters from samples). I review the use and misuse of SD and SE in several authoritative medical journals and make suggestions to help clarify the usage and meaning of SD and SE in biomedical reports. PMID:7124681

The standard deviation in fluorescence correlation spectroscopy.  

PubMed Central

The standard deviation (SD) in fluorescence correlation spectroscopy (FCS) has been mostly neglected in applications. However, the knowledge of the correct SD is necessary for an accurate data evaluation, especially when fitting theoretical models to experimental data. In this work, an algorithm is presented that considers the essential features of FCS. It allows prediction of the performance of FCS measurements in various cases, which is important for finding optimal experimental conditions. The program calculates the SD of the experimental autocorrelation function online. This procedure leads to improved parameter estimation, compared to currently used theoretical approximations for the SD. Three methods for the calculation of the SD are presented and compared to earlier analytical solutions (D. E. Koppel. 1974. Phys. Rev. A. 10:1938-1945.), calculation directly from fluorescence intensity values, by averaging several FCS measurements, or by dividing one measurement into a set of shorter data packages. Although the averaging over several measurements yields accurate estimates for the SD, the other two methods are considerably less time consuming, can be run online, and yield comparable results.

The missing ingredient in effective-medium theories: standard deviations  

NASA Astrophysics Data System (ADS)

Effective-medium theories for electromagnetic constitutive parameters of particulate composite materials are theories of averages. Standard deviations are absent because of the lack of rigorous theories. But ensemble averages and standard deviations can be calculated from a rigorous theory of reflection by planar multilayers. Average reflectivities at all angles of incidence and two orthogonal polarization states for a multilayer composed of two kinds of electrically thin layers agree well with reflectivities for a single layer with the same overall thickness and a volume-weighted average of the relative permittivities of these two components. But the relative standard deviation can be appreciable depending on the angle of incidence and the polarization state of the incident illumination, and increases with increasing difference between the constitutive parameters of the two layers. This suggests that average constitutive parameters obtained from effective-medium theories do not have uniform validity for all calculations in which they might be used.

Variances and uncertainties of the sample laboratory-to-laboratory variance (S(L)2) and standard deviation (S(L)) associated with an interlaboratory study.  

PubMed

The validation process for an analytical method usually employs an interlaboratory study conducted as a balanced completely randomized model involving a specified number of randomly chosen laboratories, each analyzing a specified number of randomly allocated replicates. For such studies, formulas to obtain approximate unbiased estimates of the variance and uncertainty of the sample laboratory-to-laboratory (lab-to-lab) STD (S(L)) have been developed primarily to account for the uncertainty of S(L) when there is a need to develop an uncertainty budget that includes the uncertainty of S(L). For the sake of completeness on this topic, formulas to estimate the variance and uncertainty of the sample lab-to-lab variance (S(L)2) were also developed. In some cases, it was necessary to derive the formulas based on an approximate distribution for S(L)2. PMID:22468367

Teaching Standard Deviation by Building from Student Invention  

NASA Astrophysics Data System (ADS)

First-year physics laboratories are often driven by a mix of goals that includes the illustration or discovery of basic physics principles and a myriad of technical skills involving specific equipment, data analysis, and report writing. The sheer number of such goals seems guaranteed to produce cognitive overload, even when highly detailed ``cookbook'' instructions are given. Recent studies indicate that this approach leaves students with a poor conceptual understanding of one of the most important features of laboratory physics and of the real world of science, in general: the development of an understanding of the nature of measurement and its attendant uncertainty1. While students might be able to reproduce certain technical manipulations of data, as novice thinkers they lack the mental scaffolding that allows an expert to organize and apply this knowledge.2,3 Our goal is to put novices on the path to expertise, so that they will be able to transfer their knowledge to novel situations.

Standard Deviation and Intra Prediction Mode Based Adaptive Spatial Error Concealment (SEC) in H.264/AVC  

NASA Astrophysics Data System (ADS)

Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Therefore an error concealment scheme is applied at the video receiver side to mask the damaged video. Considering there are 3 types of MBs (Macro Blocks) in natural video frame, i. e., Textural MB, Edged MB, and Smooth MB, this paper proposes an adaptive spatial error concealment which can choose 3 different methods for these 3 different MBs. For criteria of choosing appropriate method, 2 factors are taken into consideration. Firstly, standard deviation of our proposed edge statistical model is exploited. Secondly, some new features of latest video compression standard H.264/AVC, i. e., intra prediction mode is also considered for criterion formulation. Compared with previous works, which are only based on deterministic measurement, proposed method achieves the best image recovery. Subjective and objective image quality evaluations in experiments confirmed this.

MUSiC - Model-independent search for deviations from Standard Model predictions in CMS  

NASA Astrophysics Data System (ADS)

We present an approach for a model independent search in CMS. Systematically scanning the data for deviations from the standard model Monte Carlo expectations, such an analysis can help to understand the detector and tune event generators. By minimizing the theoretical bias the analysis is furthermore sensitive to a wide range of models for new physics, including the uncounted number of models not-yet-thought-of. After sorting the events into classes defined by their particle content (leptons, photons, jets and missing transverse energy), a minimally prejudiced scan is performed on a number of distributions. Advanced statistical methods are used to determine the significance of the deviating regions, rigorously taking systematic uncertainties into account. A number of benchmark scenarios, including common models of new physics and possible detector effects, have been used to gauge the power of such a method. )

Converting Tanner-Whitehouse reference tricep and subscapular skinfold measurements to standard deviation scores.  

PubMed

The use of conventional standard deviation (SD) scores is inappropriate when data are not normally distributed, as is the case with the tricep and subscapular skinfolds. However, it is now possible to summarize centile data in three age-specific parameters (called L, M and S) and by the appropriate use of these parameters, SD scores for skinfold measurements can be calculated that take into account skewness in the centile data. The L, M and S parameters for the tricep and subscapular skinfolds from age 1 to 19 years [J. M. Tanner & R. H. Whitehouse (1975) Arch. Dis. Childh. 50, 142-145] are presented and the equation for the calculation of SD scores described. PMID:8404792

Estimation of the standard deviation in three-dimensional microscopy by spatial statistics.  

PubMed

Usually, the calibration process for three-dimensional microscopy involves the use of a reference flat surface. The random fluctuations of the topographic image for this reference surface are used for determining the uncertainty of the microscope. When the sample material or the measuring conditions of the microscope are modified (such as the objective used in a confocal microscope, or the tip in an atomic force microscope), the measuring conditions vary and thus a new calibration is required. In this work, a technique based on spatial statistics methods (more specifically, the variogram function) is proposed to determine accurately the standard deviation for three-dimensional microscopy that does not require a reference flat surface and therefore eliminates the need for a previous calibration process of this parameter.

Repeatable source, site, and path effects on the standard deviation for empirical ground-motion prediction models  

USGS Publications Warehouse

In this study, we quantify the reduction in the standard deviation for empirical ground-motion prediction models by removing ergodic assumption.We partition the modeling error (residual) into five components, three of which represent the repeatable source-location-specific, site-specific, and path-specific deviations from the population mean. A variance estimation procedure of these error components is developed for use with a set of recordings from earthquakes not heavily clustered in space.With most source locations and propagation paths sampled only once, we opt to exploit the spatial correlation of residuals to estimate the variances associated with the path-specific and the source-location-specific deviations. The estimation procedure is applied to ground-motion amplitudes from 64 shallow earthquakes in Taiwan recorded at 285 sites with at least 10 recordings per site. The estimated variance components are used to quantify the reduction in aleatory variability that can be used in hazard analysis for a single site and for a single path. For peak ground acceleration and spectral accelerations at periods of 0.1, 0.3, 0.5, 1.0, and 3.0 s, we find that the singlesite standard deviations are 9%-14% smaller than the total standard deviation, whereas the single-path standard deviations are 39%-47% smaller.

Estimation of Radiation Exposure for Brain Perfusion CT: Standard Protocol Compared With Deviations in Protocol.  

PubMed

OBJECTIVE. The purpose of this study was to measure the organ doses and estimate the effective dose for the standard brain perfusion CT protocol and erroneous protocols. MATERIALS AND METHODS. An anthropomorphic phantom with metal oxide semiconductor field effect transistor (MOSFET) detectors was scanned on a 64-MDCT scanner. Protocol 1 used a standard brain perfusion protocol with 80 kVp and fixed tube current of 200 mA. Protocol 2 used 120 kVp and fixed tube current of 200 mA. Protocol 3 used 120 kVp with automatic tube current modulation (noise index, 2.4; minimum, 100 mA; maximum, 520 mA). RESULTS. Compared with protocol 1, the effective dose was 2.8 times higher with protocol 2 and 7.8 times higher with protocol 3. For all protocols, the peak dose was highest in the skin, followed by the brain and calvarial marrow. Compared with protocol 1, the peak skin dose was 2.6 times higher with protocol 2 and 6.7 times higher with protocol 3. The peak skin dose for protocol 3 exceeded 3 Gy. The ocular lens received significant scatter radiation: 177 mGy for protocol 2 and 435 mGy for protocol 3, which were 4.6 and 11.3 times the dose for protocol 1, respectively. CONCLUSION. Compared with the standard protocol, erroneous protocols of increasing the tube potential from 80 kVp to 120 kVp will lead to a three- to fivefold increase in organ doses, and concurrent use of high peak kilovoltage with incorrectly programmed tube current modulation can increase dose to organs by 7- to 11-fold. Tube current modulation with a low noise index can lead to doses to the skin and ocular lens that are close to thresholds for tissue reactions. PMID:24063388

ARFI cut-off values and significance of standard deviation for liver fibrosis staging in patients with chronic liver disease.  

PubMed

Background. Acoustic radiation force impulse (ARFI) elastometry quantifies hepatic stiffness, and thus degree of fibrosis, non-invasively. Our aim was to analyse the diagnostic accuracy of ARFI cut-off values, and the significance of a defined limit of standard deviation (SD) as a potential quality parameter for liver fibrosis staging in patients with chronic liver diseases (CLD). Material and methods. 153 patients with CLD (various aetiologies) undergoing liver biopsy, and an additional 25 patients with known liver cirrhosis, were investigated. ARFI measurements were performed in the right hepatic lobe, and correlated with the histopathological Ludwig fibrosis score (inclusion criteria: at least 6 portal tracts). The diagnostic accuracy of cut-off values was analysed with respect to an SD limit of 30% of the mean ARFI value. Results. The mean ARFI elastometry showed 1.95 ± 0.87 m/s (range 0.79-4.40) in 178 patients (80 female, 98 male, mean age: 52 years). The cut-offs were 1.25 m/s for F ? 2, 1.72 m/s for F ? 3 and 1.75 m/s for F = 4, and the corresponding AUROC 80.7%, 86.2% and 88.7%, respectively. Exclusion of 31 patients (17.4%) with an SD higher than 30% of the mean ARFI improved the diagnostic accuracy: The AUROC for F ? 2, F ? 3 and F = 4 were 86.1%, 91.2% and 91.5%, respectively. Conclusion. The diagnostic accuracy of ARFI can be improved by applying a maximum SD of 30% of the mean ARFI as a quality parameter - which however leads to an exclusion of a relevant number of patients. ARFI results with a high SD should be interpreted with caution. PMID:24114824

Standard operation procedures for conducting the on-the-road driving test, and measurement of the standard deviation of lateral position (SDLP).  

PubMed

This review discusses the methodology of the standardized on-the-road driving test and standard operation procedures to conduct the test and analyze the data. The on-the-road driving test has proven to be a sensitive and reliable method to examine driving ability after administration of central nervous system (CNS) drugs. The test is performed on a public highway in normal traffic. Subjects are instructed to drive with a steady lateral position and constant speed. Its primary parameter, the standard deviation of lateral position (SDLP), ie, an index of 'weaving', is a stable measure of driving performance with high test-retest reliability. SDLP differences from placebo are dose-dependent, and do not depend on the subject's baseline driving skills (placebo SDLP). It is important that standard operation procedures are applied to conduct the test and analyze the data in order to allow comparisons between studies from different sites. PMID:21625472

Calculating the interindividual geometric standard deviation for use in the integrated exposure uptake biokinetic model for lead in children.  

PubMed Central

The integrated exposure uptake biokinetic (IEUBK) model, recommended for use by the U.S. Environmental Protection Agency at residential Superfund sites to predict potential risks to children from lead exposure and to establish lead remediation levels, requires an interindividual geometric standard deviation (GSDi) as an essential input parameter. The GSDi quantifies the variability of blood lead concentrations for children exposed to similar environmental concentrations of lead. Estimates of potential risks are directly related to the GSDi, and therefore the GSDi directly impacts the scope of remediation at Superfund sites. Site-specific GSDi can be calculated for sites where blood lead and environmental lead have been measured. This paper uses data from blood and environmental lead studies conducted at the Bingham Creek and Sandy, Utah, Superfund sites to calculate GSDi using regression modeling, box modeling, and structural equation modeling. GSDis were calculated using various methods for treating values below the analytical method detection and quantitation limits. Treatment of nonquantifiable blood lead concentrations affected the GSDi more than the statistical method used to calculate the GSDi. For any given treatment, the different statistical methods produced similar GSDis. Because of the uncertainties associated with data in the blood lead studies, we recommend that a range of GSDis be used when analyzing site-specific risks associated with exposure to environmental lead instead of a single estimate. Because the different statistical methods produce similar GSDis, we recommend a simple procedure to calculate site-specific GSDi from a scientifically sound blood and environmental lead study.

Standard deviation of the mean and other time series properties of voltages measured with a digital lock-in amplifier  

NASA Astrophysics Data System (ADS)

We investigate some statistical properties of ac voltages from a white noise source measured with a digital lock-in amplifier equipped with finite impulse response output filters which introduce correlations between successive voltage values. The main goal of this work is to propose simple solutions to account for correlations when calculating the standard deviation of the mean (SDM) for a sequence of measurement data acquired using such an instrument. The problem is treated by time series analysis based on a moving average model of the filtering process. Theoretical expressions are derived for the power spectral density (PSD), the autocorrelation function, the equivalent noise bandwidth and the Allan variance; all are related to the SDM. At most three parameters suffice to specify any of the above quantities: the filter time constant, the time between successive measurements (both set by the lock-in operator) and the PSD of the white noise input, h0. Our white noise source is a resistor so that the PSD is easily calculated; there are no free parameters. Theoretical expressions are checked against their respective sample estimates and, with the exception of two of the bandwidth estimates, agreement to within 11% or better is found.

We deal with a class of abstract nonlinear stochastic models, which covers many 2D hydrodynamical models including 2D Navier-Stokes equations, 2D MHD models and the 2D magnetic Benard problem and also some shell models of turbulence. We state the existence and uniqueness theorem for the class considered. Our main result is a Wentzell-Freidlin type large deviation principle for small multiplicative noise which we prove by a weak convergence method.

Vibrational investigation on FT-IR and FT-Raman spectra, IR intensity, Raman activity, peak resemblance, ideal estimation, standard deviation of computed frequencies analyses and electronic structure on 3-methyl-1,2-butadiene using HF and DFT (LSDA/B3LYP/B3PW91) calculations  

NASA Astrophysics Data System (ADS)

FT-IR and FT-Raman (4000-100 cm -1) spectral measurements of 3-methyl-1,2-butadiene (3M12B) have been attempted in the present work. Ab-initio HF and DFT (LSDA/B3LYP/B3PW91) calculations have been performed giving energies, optimized structures, harmonic vibrational frequencies, IR intensities and Raman activities. Complete vibrational assignments on the observed spectra are made with vibrational frequencies obtained by HF and DFT (LSDA/B3LYP/B3PW91) at 6-31G(d,p) and 6-311G(d,p) basis sets. The results of the calculations have been used to simulate IR and Raman spectra for the molecule that showed good agreement with the observed spectra. The potential energy distribution (PED) corresponding to each of the observed frequencies are calculated which confirms the reliability and precision of the assignment and analysis of the vibrational fundamentals modes. The oscillation of vibrational frequencies of butadiene due to the couple of methyl group is also discussed. A study on the electronic properties such as HOMO and LUMO energies, were performed by time-dependent DFT (TD-DFT) approach. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecule. The thermodynamic properties of the title compound at different temperatures reveal the correlations between standard heat capacities ( C) standard entropies ( S), and standard enthalpy changes ( H).

Use of Fat Mass and Fat Free Mass Standard Deviation Scores Obtained Using Simple Measurement Methods in Healthy Children and Patients: Comparison with the Reference 4-Component Model  

PubMed Central

Background Clinical application of body composition (BC) measurements for individual children has been limited by lack of appropriate reference data. Objectives (1) To compare fat mass (FM) and fat free mass (FFM) standard deviation scores (SDS) generated using new body composition reference data and obtained using simple measurement methods in healthy children and patients with those obtained using the reference 4-component (4-C) model; (2) To determine the extent to which scores from simple methods agree with those from the 4-C model in identification of abnormal body composition. Design FM SDS were calculated for 4-C model, dual-energy X-ray absorptiometry (DXA; GE Lunar Prodigy), BMI and skinfold thicknesses (SFT); and FFM SDS for 4CM, DXA and bioelectrical impedance analysis (BIA; height2/Z)) in 927 subjects aged 3.8–22.0 y (211 healthy, 716 patients). Results DXA was the most accurate method for both FM and FFM SDS in healthy subjects and patients (mean bias (limits of agreement) FM SDS 0.03 (±0.62); FFM SDS ?0.04 (±0.72)), and provided best agreement with the 4-C model in identifying abnormal BC (SDS ??2 or ?2). BMI and SFTs were reasonable predictors of abnormal FM SDS, but poor in providing an absolute value. BIA was comparable to DXA for FFM SDS and in identifying abnormal subjects. Conclusions DXA may be used both for research and clinically to determine FM and FFM SDS. BIA may be used to assess FFM SDS in place of DXA. BMI and SFTs can be used to measure adiposity for groups but not individuals. The performance of simpler techniques in monitoring longitudinal BC changes requires investigation. Ultimately, the most appropriate method should be determined by its predictive value for clinical outcome.

A model for evolution of oxygen potential and stoichiometry deviation in irradiated UO2 fuel  

NASA Astrophysics Data System (ADS)

A model for radial redistribution of oxygen in irradiated UO2 fuel under conditions of temperature and fission rate gradients has been developed. The oxygen transport in irradiated fuel is considered as a two-scale problem. On the local scale defined by the grain size, irradiated fuel is considered as a multi-phase system including solid solution of fission products in UO2 matrix, solid precipitates (metal phase, grey phase of complex ternary compounds, the phase of condensed CsI) formed at the gas/solid interface and the gas phase in the intergranular bubbles. Intraganular transport of fission products is described by a set of diffusion equations which are supplemented by the condition of partial thermochemical equilibrium in the subsystem "precipitates & gas phase". The boundary conditions are formulated basing on thermochemical equilibrium on the interface of subsystems "solid solution" and "precipitates & gas phase". Calculation of the partial thermochemical equilibrium yields local values of the oxygen chemical potential and the deviation from fuel stoichiometry. On the global scale defined by the fuel pellet size, spatial variations of the oxygen potential caused by the temperature gradients or the presence of sources/sinks at the pellet boundary determine thermal diffusion fluxes resulting in redistribution of oxygen. The whole set of equations describing local equilibration and the transport in the local and global scales is solved in a self-consistent manner. The model results for radial distribution of oxygen potential of UO2 calculated for typical reactor operating conditions and the fuel burnup up ˜100 MW d/kg HM are in satisfactory agreement with experimental data.

On using a normal approximation for the noncentral t-distribution in determining upper limits for future sample relative repeatability and reproducibility standard deviations.  

PubMed

Formulas, based on a normal approximation for the noncentral t-distribution, were developed to compute 100p% one-tailed upper limits for future sample relative repeatability and relative reproducibility standard deviations (RSDr,% and RSDR,%) collaboratively obtained under a completely randomized model. The accuracy of the formulas for obtaining a one-tailed upper limit for the future sample RSDr,% was assessed by comparing the computed noncentral t-distribution-based upper limits with the one-tailed upper limits based on a normal approximation for the noncentral t-distribution. The accuracy of the normal approximation formula for obtaining a one-tailed upper limit for a future sample RSDR,% was assessed by comparing the formula-based one-tailed upper limits with those obtained in a Monte Carlo simulation study.

SUPPLEMENTARY COMPARISON: Final report on international comparisons of national standards in the field of measurements of deviations from straightness and flatness with the measurement range of deviations from straightness from 0 to 50 µm, the length of surface from 0.4 to 5 m  

NASA Astrophysics Data System (ADS)

The aim of the project was to ensure the reliability of length measurement unit transfer in the field of measurement of deviations from straightness and flatness and to confirm the claimed measurement capabilities of the national state measurement standards of Republic of Belarus, Republic of Kazakhstan and Russia. The comparison was conducted on a granite bridge of the Kazakhstan measurement standard by the measurement of its deviations from straightness using instruments which are parts of the national measurement standards of comparison participants and which they brought. The measurement results were processed, the uncertainty budgets and the confidence levels were determined, and the results were analyzed. In summary: The comparison was successfully carried out and the obtained results confirmed the measuring capabilities claimed by the participants. The reference value was calculated using arithmetical mean, weighted arithmetical mean and median of deviations from straightness of the bridge. The value 6.86 µm was chosen as the reference value with an associated expanded uncertainty of 0.52 µm. The deviation of the measurement result from the reference value of each comparison participant is, in absolute value, always smaller than or equal to the expanded uncertainty of the participant. The analysis of pair-wise equivalence shows that the estimate of difference of measurement results (systematic bias) of each possible pair of comparison participants does not exceed the expanded uncertainty of this estimate. The obtained results confirm the equivalence of participating laboratories. The results of additional comparisons which have been carried out can be presented together with those of the COOMET and BIPM ones. Main text.

Planning and drilling geothermal energy extraction hole EE-2: a precisely oriented and deviated hole in hot granitic rock  

SciTech Connect

During the preceding work (Phase I) of the Hot Dry Rock (HDR) Geothermal Energy Project at Fenton Hill, two holes were drilled to a depth of nearly 3048 m (10,000 ft) and connected by a vertical hydraulic fracture. In this phase, water was pumped through the underground reservoir for approximately 417 days, producing an energy equivalent of 3 to 5 MW(t). Energy Extraction Hole No. 2 (EE-2) is the first of two deep holes that will be used in the Engineering-Resource Development System (Phase II) of the ongoing HDR Project of the Los Alamos National Laboratory. This phase of the work consists of drilling two parallel boreholes, inclined in their lower, open-hole sections at 35/sup 0/ to the vertical and separated by a vertical distance of 366 m (1200 ft) between the inclined parts of the drill holes. The holes will be connected by a series of vertical, hydraulically produced fractures in the Precambrian granitic rock complex. EE-2 was drilled to a depth of 4660 m (15,289 ft), where the bottom-hole temperature is approximately 320/sup 0/C (608/sup 0/F). Directional drilling techniques were used to control the azimuth and deviation of the hole. Upgrading of the temperature capability of existing hardware, and development of new equipment was necessary to complete the drilling of the hole in the extremely hot, hard, and abrasive granitic formation. The drilling history and the problems with bits, directional tools, tubular goods, cementing, and logging are described. A discussion of the problems and recommendations for overcoming them are also presented.

Determination of a two-tailed 100(1-alpha)% upper limit on the relative error in the laboratory-to-laboratory standard deviation obtained from an interlaboratory study.  

PubMed

For some classes of analytical methods, it is assumed that the error in the laboratory-to-laboratory standard deviation (S(L)) is appreciable. To demonstrate the magnitude of this error in S(L) for such methods, formulas were derived to obtain a two-tailed 100(1-alpha)% upper limit on the relative error in S(L) obtained from an interlaboratory study, assuming that the laboratory-to-laboratory variance (S(L)2) obtained in the validation of an analytical method is approximately normal and/or Chi-square distributed. This 100(1-alpha)% upper limit (delta(1-alpha/2)) is referred to as a margin of relative error in S(L) (MRE(S(L. Monte Carlo simulations were performed, and the results compared satisfactorily with the formula calculations. To aid in designing future interlaboratory studies in which concern is focused on the magnitude of the uncertainty in S(L), expressed as a proportion of the true value (sigma L), a formula was derived to determine the number of laboratories needed to attain a given MRE in S(L) for a stated number of replicates per laboratory.

Geometry drives the "deviated-bending" of the bi-tubular structures of the 9 + 2 axoneme in the flagellum.  

PubMed

The axoneme "9 + 2" is basically a system constituted of a cylinder of 9 microtubule doublets surrounding a central pair of microtubules. These bi-tubular structures are considered as the support system of the active molecular complexes that generate and regulate the axonemal movement. Schoutens has calculated their moments of inertia [Schoutens, 1994: Journal of Theoretical Biology 171:163-177]. The results obtained allowed us to assume that these bi-tubular systems are endowed with dynamic properties that could be involved in the regulation of the axonemal machinery. For the first time, using the finite elements methods and the resistance of material principles, we have now calculated that the curvature of the axoneme induces the deviated-bending of the bi-tubular structures of the axoneme, because of their geometry only; they behave as beams in a framework. This approach is similar to the one used to measure the deflection of a single microtubule [Kasas et al., 2004: Chem Phys Chem 5:252-257]. These behaviors induce internal movement or constraints of either couples or triplets of doublets within the axonemal cylinder that could be directly involved in a constrained or a spontaneous "convergence/divergence" equilibrium of the cylindrical generatrices that they draw along the axonemal cylinder, which could apparently regulate the activity of the axonemal motors (the dynein arms). These results are discussed here, taking into consideration the dynamic propagation of the wave train along the flagellar axoneme, and the regulated balance between the activities of the two opposite sides of the axoneme during the beat. This study raises a few questions about the architecture-activity duo of the axonemal doublets. PMID:15368611

Low angle deviation from the anisotropic effective mass model in epitaxial YBa2(Cu1-xZnx)3O7-? thin films  

NASA Astrophysics Data System (ADS)

The magnetic field effect on the electrical in-plane resistivity ?ab has been investigated for high quality c-axis oriented YBa2(Cu1-xZnx)3O7-? thin films (x=0.02 and 0.04) by magnetoresistance measurements up to 20 Teslas for different orientations of the magnetic field with respect to the a-b plane, at different temperatures below Tc. Deviation in the scaling behaviour expected from tile anisotropic effective mass model is observed for small misalignement between the magnetic field direction and the superconducting CuO2 planes, which is attributed to the intrinsic pinning effect. The Zn doping influence on the anisotropic ratio ? = ?ab/?c is studied from the high angle scaling properties of the film.

Variability of gait characterized by normalized deviation.  

PubMed

The purpose of this study was to investigate the influence of sport, age and different orthopeadical diseases on the variability of gait. 45 healthy, young subjects, 11 professional hand ball players, 24 patients after medial meniscectomy, 20 elderly, healthy subjects, and 20 patients with hip osteoarthritis were examined. The average, the standard deviation and the normalized deviation of spatial and temporal parameters were calculated for each person examined and in each group. Our data suggested that the normalized deviation of parameters enables the modelling of dynamic perception, because it is independent of parameter values due to normalization. Our tests show that the size of the parameter is independent of lateral dominance in healthy subjects. The magnitude of the coefficient of the variation of parameters depends on age, on the intensity of sports activities, and on orthopaedical diseases. PMID:20653320

Revisiting N2 fixation in the North Atlantic Ocean: Significance of deviations from the Redfield Ratio, atmospheric deposition and climate variability  

NASA Astrophysics Data System (ADS)

The average oceanic nitrate-to-phosphate molar ratio (NO3-:PO43-?16:1, referred to as the Redfield Ratio) in subsurface waters, which is similar to the average ratio of particulate nitrogen (N)-to-phosphorus (P) in phytoplankton, is the cornerstone in calculating geochemical estimates of N2 fixation and denitrification rates. Any deviations from this canonical Redfield Ratio in intermediate ocean waters, expressed as N* (a measure of NO3- in excess or deficit of 16×PO43-), provides an integrated estimate of net N fluxes into and out of the ocean. In well-oxygenated ocean basins such as the North Atlantic Ocean, N* estimates are usually positive and can be used to infer that rates of N2 fixation exceed rates of denitrification. We use this approach to estimate N2 fixation over the last two decades (1988-2009) based on data collected at the Bermuda Atlantic Time-series Study (BATS) site in the North Atlantic Ocean near Bermuda. Our results indicate that interpretation of the N* tracer as an estimate of N2 fixation should be undertaken with caution, as N2 fixation is not the only process that results in a positive N* estimate. The impacts of a locally variable nitrogen-to-phosphorus ratio, relative to the fixed Redfield Ratio, in the suspended particulate matter as well as in the subsurface water nutrients and atmospheric N deposition on N* variability were examined. Furthermore, we explored the role of climate modes (i.e., North Atlantic Oscillation and Arctic Oscillation) on N* variability. We found that N* in the subsurface waters was significantly affected by these factors and hence previous estimates of N2 fixation using this technique might have been substantially overestimated. Our revised estimate of N2 fixation in the North Atlantic Ocean (0°N-50°N, 20°W-80°W) is 12.2±0.9×1011 mol N yr-1, and based on long-term BATS data provides better constraints than both earlier indirect and direct estimates N2 fixation.

Comparison of the standard theory predictions of MW and sin?2?efflept with their experimental values  

NASA Astrophysics Data System (ADS)

Assuming that the recently discovered particle at LHC is the standard theory (ST) Higgs boson, we compare the ST predictions of MW and sin?2?efflept with the experimental values of these basic observables. While the sin?2?efflept prediction is in excellent agreement with its experimental value, that of MW shows a 1.33? deviation. Implications of these comparisons for possible future developments at LHC and a future GigaZ linear collider are briefly discussed. It is also pointed out that these comparisons are consistent with the conjecture that the newly discovered particle is indeed the ST Higgs boson.

Large deviations of Lyapunov exponents  

NASA Astrophysics Data System (ADS)

Generic dynamical systems have ‘typical’ Lyapunov exponents, measuring the sensitivity to small perturbations of almost all trajectories. A generic system also has trajectories with exceptional values of the exponents, corresponding to unusually stable or chaotic situations. From a more mathematical point of view, large deviations of Lyapunov exponents characterize phase-space topological structures such as separatrices, homoclinic trajectories and degenerate tori. Numerically sampling such large deviations using the Lyapunov Weighted Dynamics allows one to pinpoint, for example, stable configurations in celestial mechanics or collections of interacting chaotic ‘breathers’ in nonlinear media. Furthermore, we show that this numerical method allows one to compute the topological pressure of extended dynamical systems, a central quantity in the thermodynamic of trajectories of Ruelle. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Lyapunov analysis: from dynamical systems theory to applications’.

Nasal septal deviation in a mediaeval population.  

PubMed

In modern populations, there is evidence that nasal septal deviation (NSD) may be associated with maxillary sinusitis, and that those with NSD may differ in craniofacial morphology from those without or with less severe NSD. Whether these associations hold true for earlier populations has yet to be investigated. The current work is a step toward remedying this. The study group comes from a mediaeval English archaeological site. NSD was quantified using image analysis. Maxillary sinusitis was identified from new bone formation in the antrum. Cranial morphology was assessed using standard craniometric measurements. The results provided no evidence for a relationship between NSD and maxillary sinus disease. NSD was associated with reduced measures of upper facial height, suggesting decoupling of growth in vertical height of the nasal septum and the bony structures surrounding it. PMID:22565652

High precision calibration for 2D optical standard  

NASA Astrophysics Data System (ADS)

Photomask is a kind of 2-D optical standard with etched orthogonal coordinates made of a glass substrate chrominged or filmed with other metal. In order to solve the problems of measurement and traceability of ultra precision photomasks used in advanced manufacturing industry, 2-D photomask optical standard was calibrated in high precision laser two coordinate standard device. A high precision differential laser interferometer system was used for a length standard, a high magnification optical micro vision system was used for precision optical positioning feedback. In this paper, a image measurement model was purposed; A sampling window auto identification algorithm was designed. Grid stripe image could be identified and aimed at automatically by this algorithm. An edge detection method based on bidirection progressive scanning and 3-sigma rule for eliminating outliers in sampling window was found. Dirty point could be removed with effect. Edge detection error could be lowered. By this means, the measurement uncertainty of 2-D optical standard's ruling span was less than 0.3 micrometer (k=2).

WA1ms: a ~2.61 Ga muscovite standard for 40Ar/39Ar dating  

NASA Astrophysics Data System (ADS)

The 40Ar/39Ar dating technique requires the use of neutron fluence monitors (standards) to allow calculating the age of a sample. Precise calibrations of these standards are crucial to obtain accurate age and decrease the uncertainties associated with 40Ar/39Ar dates. Few fully intercalibrated 40Ar/39Ar standards are currently in use in the argon community, including: Hb3gr hornblende [1080.4 ± 1.1 Ma]; TC sanidine [28.619 ± 0.034]; FC sanidine [28.305 ± 0.036 Ma]; GA1550 biotite [99.769 ± 0.108 Ma] and AC sanidine [1.2061 ± 0.0019 Ma] (all the present ages are calculated using the decay constants of [1] and are reported at 1?). All these standards show an excellent grain-to-grain reproducibility with for example an average relative standard deviation of the F-value (40Ar*/39ArK) of 0.38% and 0.59% for FCs and Hb3gr, respectively. Ideally, available standards should span a range of age along the geological timescale and include a variety of minerals to be able to 1) minimize the isotopic range between the standard and the unknown (i.e. similar age) and 2) allow loading standard grains that are optically different from the unknown, to avoid accidental mixing within the irradiation discs. On a more practical aspect, Ca-free standard should be available to allow rapid measurement of standard grains upon irradiation without the need to wait few months for 37Ar* to decay. For Precambrian samples, only Hb3gr (~1.08 Ga) and NL-25 (~2.65 Ga) are in the right range of age to allow optimal sample age measurement. Whereas Hb3gr showed a good grain-to-grain reproducibility [2, 3], modern mass spectrometric and laser techniques have shown that NL-25 hornblende failed to give reproducible single-grain ages with a relative standard deviation of the F-value of 2.3% [3], leaving Hb3gr the only reliable standard for this period of time. Here, we present intercalibration results for a new ~2.6 Ga standard. WA1ms is a muscovite extracted from an Archean shear zone in the Lake Johnston greenstone belt, Western Australia. So far, WA1ms has been investigated over 3 irradiations of 25 hours, several disc positions, and two grains sizes of 125-215 ?m and 215-300 ?m and has been calibrated against FCs and GA1550 (Hb3gr in progress). We carried out 35 total fusion measurements and 4 step-heating experiments. Flat age spectra and an average F-value relative standard deviation of 0.57% (34/35 analyses; MSWD = 0.97; P = 0.52) demonstrate the reproducibility of WA1ms and its suitability as a reliable 40Ar/39Ar standard. Based on the 34 total fusion ages, we calculated R[WA1ms/FCs] = 205.59 ± 0.35 and R[WA1ms/GA1550] = 57.24 ± 0.09 with a resulting weighted mean age for WA1ms of 2610.3 ± 2.0 Ma (± 0.08%, 1?). This correspond to a 40Ar*/40K value of (3.3776±0.0026) x 10-1, which is independent of the value of the decay constant used for calculation. In addition, WA1 muscovite does not require any post-irradiation waiting time (no 37Ar decay) and can be analysed readily upon return from the reactor (a typical waiting period for Hb3gr is four months). WA1ms is freely available to the argon community upon request. [1] Renne et al. GCA 2010; [2] Jourdan et al., Chem. Geol. 2007 ; [3] Jourdan and Renne, GCA 2007.

Analysis of using the tongue deviation angle as a warning sign of a stroke  

PubMed Central

Background The symptom of tongue deviation is observed in a stroke or transient ischemic attack. Nevertheless, there is much room for the interpretation of the tongue deviation test. The crucial factor is the lack of an effective quantification method of tongue deviation. If we can quantify the features of the tongue deviation and scientifically verify the relationship between the deviation angle and a stroke, the information provided by the tongue will be helpful in recognizing a warning of a stroke. Methods In this study, a quantification method of the tongue deviation angle was proposed for the first time to characterize stroke patients. We captured the tongue images of stroke patients (15 males and 10 females, ranging between 55 and 82 years of age); transient ischemic attack (TIA) patients (16 males and 9 females, ranging between 53 and 79 years of age); and normal subjects (14 males and 11 females, ranging between 52 and 80 years of age) to analyze whether the method is effective. In addition, we used the receiver operating characteristic curve (ROC) for the sensitivity analysis, and determined the threshold value of the tongue deviation angle for the warning sign of a stroke. Results The means and standard deviations of the tongue deviation angles of the stroke, TIA, and normal groups were: 6.9?±?3.1, 4.9?±?2.1 and 1.4?±?0.8 degrees, respectively. Analyzed by the unpaired Student’s t-test, the p-value between the stroke group and the TIA group was 0.015 (>0.01), indicating no significant difference in the tongue deviation angle. The p-values between the stroke group and the normal group, as well as between the TIA group and the normal group were both less than 0.01. These results show the significant differences in the tongue deviation angle between the patient groups (stroke and TIA patients) and the normal group. These results also imply that the tongue deviation angle can effectively identify the patient group (stroke and TIA patients) and the normal group. With respect to the visual examination, 40% and 32% of stroke patients, 24% and 16% of TIA patients, and 4% and 0% of normal subjects were found to have tongue deviations when physicians “A” and “B” examined them. The variation showed the essentiality of the quantification method in a clinical setting. In the receiver operating characteristic curve (ROC), the Area Under Curve (AUC, = 0.96) indicates good discrimination. The tongue deviation angle more than the optimum threshold value (= 3.2°) predicts a risk of stroke. Conclusions In summary, we developed an effective quantification method to characterize the tongue deviation angle, and we confirmed the feasibility of recognizing the tongue deviation angle as an early warning sign of an impending stroke.

Synthesis and Crystal Structure Determinations in the ? and ? Phase Domains of the Iron-Zinc System: Electronic and Bonding Analysis of Fe13Zn39 and FeZn10, a Subtle Deviation from the Hume-Rothery Standard?  

NASA Astrophysics Data System (ADS)

The iron-zinc system has been investigated in the zinc-rich domain. Alloying of Fe and Zn in ZnCl2 flux allowed the formation of well-developed single crystals of phases Fe13Zn39 and FeZn10 in a one-step experiment. These phases crystallize in cubic space group I43m (?) phase, Fe13Zn39, a=8.994(2) Å, Z=1) and in the hexagonal space group P63/mmc (? phase, FeZn10, a=12.787(3) Å, c=57.222(7), c/a=4.475 Å, Z~50). The structure of Fe13Zn39 was reinvestigated and refined to R(F) of 3.28% it is of the cubic Cu5Zn8 type. Its three-dimensional network is composed of fused tetrahedra of icosahedra (Fe/Zn) centered by Fe atoms. Fe/Zn occupational disorder has been accurately determined. The huge hexagonal structure of FeZn10 (c.a., Fe1.04(1)Zn10) has been determined for the first time and refined to R(F) of 6.84%. It contains 52 Fe and 504 Zn atoms and consists of a very dense packing of icosahedra and a few other polyhedra. Among the 52 independent atoms in the unit cell, seven atoms describe a disordered icosahedron spinning around a three-fold axis. Electronic properties are analyzed on the basis of tight-binding extended Hückel band calculations. The relationship of metallic bonding to clustering within the Fe13Zn39 phase has also been investigated using some electronic requirements for polyhedral condensation.

Induction of interleukin-12 production in mouse macrophages by berberine, a benzodioxoloquinolizine alkaloid, deviates CD4+ T cells from a Th2 to a Th1 response  

PubMed Central

In this study we investigated whether berberine-mediated induction of interleukin-12 (IL-12) production in antigen-presenting cells could regulate a cytokine profile of antigen-primed CD4+ T helper (Th) cells. Pretreatment with berberine induced IL-12 production in both macrophages and dendritic cells, and significantly increased the levels of IL-12 production in lipopolysaccharide-stimulated macrophages and in CD40 ligand-stimulated dendritic cells. Importantly, berberine pretreatment of macrophages increased their ability to induce interferon-? (IFN-?) and reduced their ability to induce IL-4 in antigen-primed CD4+ T cells. Berberine did not influence the macrophage cell surface expression of the class II major histocompatibility complex molecule, the co-stimulatory molecules CD80 and CD86, and intracellular adhesion molecule-1. Addition of neutralizing anti-IL-12p40 monoclonal antibody to cultures of berberine-pretreated macrophages and CD4+ T cells restored IL-4 production in antigen-primed CD4+ T cells. The in vivo administration of berberine resulted in the enhanced induction of IL-12 production by macrophages when stimulated in vitro with lipopolysaccharide or heat-killed Listeria monocytogenes, leading to the inhibition of the Th type 2 cytokine profile (decreased IL-4 and increased IFN-? production) in antigen-primed CD4+ T cells. These findings may point to a possible therapeutic use of berberine or medicinal plants containing berberine in the Th type 2 cell-mediated immune diseases such as allergic diseases.

Calibration of a molecular clock in tits (Paridae)--do nucleotide substitution rates of mitochondrial genes deviate from the 2% rule?  

PubMed

The ongoing debate on the reliability of avian molecular clocks is actually based on only a small number of calibrations carried out under different assumptions with respect to the choice and constraints of calibration points or to the use of substitution models. In this study, we provide substitution rate estimates for two mitochondrial genes, cytochrome b and the control region, and age estimates for lineage splits within four subgenera of tits (Paridae: Parus, Cyanistes, Poecile and Periparus). Overall sequence divergence between cytochrome b lineages covers a range of 0.4-1.8% per million years and is thus consistent with the frequently adopted approximation for a sequence divergence between avian lineages of 1.6-2% per my. Overall rate variation is high and encompasses the 2% value in a 95% CI for model corrected data. Mean rate estimates for cytochrome b range between 1.9 and 8.9 x 10(-3) substitutions per site per lineage. Local rates differ significantly between taxonomic levels with lowest estimates for haplotype lineages. At the population/subspecies level mean sequence divergence between lineages matches the 2% rule best for most cytochrome b datasets (1.5-1.9% per my) with maximum estimates for small isolated populations like those of the Canarian P. teneriffae complex (up to 3.9% per my). Overall rate estimates for the control region range at similar values like those for cytochrome b (2.7-8.8 x 10(-3), 0.5-1.8% per my), however, within some subgenera mean rates are higher than those for cytochrome b for uncorrected sequence data. The lowest rates for both genes were calculated for coal tits of subgenus Periparus (0.04-0.6% per my). Model-corrected sequence data tend to result in higher rate estimates than uncorrected data. Increase of the gamma shape parameter goes along with a significant decrease of rate and partly age estimates, too. Divergence times for earliest deep splits within tit subgenera Periparus and Parus were dated to the mid Miocene at 10-14my bp. Most recent splits between east and west Palearctic taxa of blue, willow and great tits were dated to the Pliocene/Pleistocene boundary with the earliest estimates based on model-corrected trees. Relaxation of the Messinian calibration point leads to more recent divergence times for North African coal and blue tit populations during the mid Pliocene. Despite a relatively broad age constraint for the split between Nearctic and Palearctic Poecile due to the Pliocene re-opening of the Bering Strait, the split between chickadees and willow tits is dated considerably earlier than in former studies to the upper bound of the age constraint at 7.4 my BP.

Mean d(2) and divergence time: transformations and standardizations.  

PubMed

The fitness consequences of inbreeding and outbreeding have intrigued biologists for a long time. Recently a measure of relatedness of parental haplotypes has been proposed called mean d(2). This measure is based on a stepwise mutational process and therefore is tailored to microsatellite genetic markers. Theoretical work suggests that mean d(2) typically is less suited for measuring fitness consequences due to close inbreeding rather than heterozygosity. However, mean d(2) may be more appropriate than heterozygosity for measuring divergence times over longer time scales and thus for detecting outbreeding depression. Here, simulations are used to (1). identify appropriate standardization coefficients and transformations for mean d(2), and (2). evaluate mean d(2) as a measure of divergence time of parental lineages over time scales up to 10000 generations. Results show that mean d(2) is a linear predictor of divergence time. The coefficient of variation of mean d(2) approaches a constant value with increasing divergence time and therefore logarithm transformation is appropriate to restore homoscedasticity. When mutation rates and sizes are known for each locus they can be incorporated into a standardization coefficient to increase the precision of mean d(2). As few as 10 loci can explain more than 70% of the variation in divergence time between lineages. While heterozygosity outperforms mean d(2) at detecting differences in divergence time over relative short time periods (2) can outperform heterozygosity at detecting differences over longer time periods (>or=1000 generations). However, gene flow of as little as 1% per generation can significantly reduce the ability of either mean d(2) or heterozygosity to estimate divergence time. PMID:15073233

EDITORIAL: Standard Materials and Metrology for Nanotechnology (SMAM-2)  

NASA Astrophysics Data System (ADS)

This issue of Measurement Science and Technology (MST) contains three papers presented at the second international symposium on Standard Materials and Metrology for Nanotechnology (SMAM-2), held in the Akihabara Convention Hall in Tokyo, Japan, on 25 and 26 May 2006. The SMAM symposium aims to emphasize the importance of standard materials and metrology (SM/M) for the development of nanotechnology, which is expected to be the most promising driving force for the development of advanced industrial science/technology in various fields. New fabrication processes based on nanotechnology will become really powerful when the processes are reproducible and reliable. The SM/M that have been developed for use in nano-scale characterization are therefore the key tools for the establishment of reliability in the areas of information, environment and biotechnology, where the application of nanotechnology is essential for their development. The symposium had four sessions featuring the most important issues in the field of SM/M: (I) Nanotechnology Standardization, (II) SM/M for Nano-particles and Nano-pores, (III) SM/M for Nanostructure Evaluation, (IV) SM/M for Thin-film Characterization. A total of 29 papers had been submitted to the SMAM-2 Publishing Committee and six papers were tentatively selected by the committee to forward to the MST editors for publication in this journal. The three papers published in this issue are epoch-making in that they present new methods and knowledge for the standard materials and metrology especially developed for nanotechnology. We hope the papers will show readers how important standard materials and metrology are for the development of nanotechnology. We appreciate very much the important contribution of those who refereed the manuscripts and we particularly want to thank the MST staff for helping in publishing this special feature. Finally we expect SMAM-3 to be held two years after SMAM-2 and we hope to attract many more participants and papers and to publish a further special feature in MST.

APPLICATION OF DOE-2 TO RESIDENTIAL BUILDING ENERGY PERFORMANCE STANDARDS  

SciTech Connect

One important requirement emerging from national and international efforts to shift from our present energy-intensive way of life to an energy conservation mode is the development of standards for assessing and regulating energy use and performance in buildings. This paper describes a life-cycle-cost approach to Building Energy Performance Standards (BEPS) calculated by using DOE-2: The Energy Use Analysis of Buildings Computer Program. The procedure outlined raises important questions that must be answered before the energy budgets devised from this approach can be reliably used as a policy tool, The DOE-2 program was used to calculate the energy consumption in prototype buildings and in their modified versions in which energy conservation measures were effected. The energy use of a modified building with lowest life-cycle-cost determines the energy budget for all buildings of that type. These calculations were based on a number of assumptions that may be controversial. These assumptions regard accuracy of the model, comparison of the DOE-2 program with other programs, stability of the energy budget, and sensitivity of the results to variations in the building parameters.

Static ocular counterroll reflex in skew deviation  

PubMed Central

Objective: The static ocular counterroll (OCR) reflex generates partially compensatory torsional eye movements during head roll. It is mediated by the utricle in the inner ear. Skew deviation is a vertical strabismus thought to be caused by imbalance in the utriculo-ocular pathway. We hypothesized that if skew deviation is indeed caused by damage to this reflex pathway, patients with skew deviation would show abnormal OCR. Methods: Eighteen patients with skew deviation caused by brainstem or cerebellar lesions and 18 normal participants viewed a target at 1 m. Ocular responses to static passive head roll-tilts of approximately 20° were recorded using search coils. Static OCR gain was calculated as the change in torsional eye position divided by the change in head position during sustained head roll. Perception of the subjective visual vertical (SVV) was also measured. Results: Group mean OCR gain was reduced by 45% in patients. At an individual level, OCR gains were asymmetric between eyes and between torsional directions in 90% of patients. In addition, the hypotropic eye incyclotorting gain was lower than the hypertropic eye excyclotorting gain during head roll toward the hypotropic eye in 94% of patients. No consistent pattern of gain asymmetry was found during head roll toward the hypertropic eye. The SVV was tilted toward the hypotropic eye. Conclusion: Static OCR gain is significantly reduced in skew deviation. Interocular and directional gain asymmetries are also prevalent. The asymmetries provide further evidence that disruption of the utriculo-ocular pathway is a mechanism for skew deviation.

Fetal liver T2* values: Defining a standardized scale.  

PubMed

PURPOSE: To define the normal T2* values of liver in the third trimester of pregnancy in normal fetuses. MATERIALS AND METHODS: Multi-echo gradient echo T2* sequence was applied to the fetal abdomen in the axial plane in women undergoing a fetal MRI (1.5 Tesla [T], MRI system). A region of interest, best visualizing in the liver parenchyma was used for measurements. Studies were independently read by two experienced readers to assess intra- and interobserver variability. RESULTS: The study cohort included 46 pregnant women undergoing fetal MRI for any indication other than liver pathology evaluation. Three scans were excluded due to fetal motion. Average maternal and gestational age were 33?±?4 years and 31.9?±?3 weeks, respectively. Average T2* values were found to be 19.7?±?7.4 ms. The intra- and interobserver agreement were very good: 0.93 and 0.8-0.084, respectively. CONCLUSION: T2* MRI allows noninvasive evaluation liver iron content in the third trimester fetus. Measured values at this stage of pregnancy are significantly lower compared with values cited in the literature for adults. This is of major importance in the correct diagnosis of fetal iron overload states. We propose this as the standard reference when evaluating fetal iron overload pathology. J. Magn. Reson.

Extensions to the Beta Secondary Standard BSS 2  

NASA Astrophysics Data System (ADS)

Since several years, the irradiation facility for beta radiation, the Beta Secondary Standard BSS 2 developed at PTB, has been in worldwide use for the performance of irradiations with calibrated beta sources. Due to recent developments in eye tumor therapy, in eye lens dosimetry, and in soft- and hardware technology, several extensions have been added to the BSS 2. These extensions are described in this paper: 1. The possibility of using a 106Ru/106Rh beta source was added as this radionuclide is often used in tumor therapy. 2. The (small) contribution due to photon radiation was included in the dose (rate) reported by the BSS 2, as this was missing in the past. 3. The quantity personal dose equivalent at a depth of 3 mm, Hp(3), was implemented due to recent findings on the radio sensitivity of the eye lens regarding cataract induction and the subsequent lowering of the dose limit from 150 mSv down to 20 mSv per year; 4. The correction for ambient conditions (air temperature, pressure, and relative humidity) was improved in order to adequately handle the quantity Hp(3) and in order to extend the range of use beyond 25°C. 5. A checksum test was added to the software to secure the calibration data against (un)intended changes. 6. The connection of the PC and the BSS 2 has been changed to a network interface (TCP/IP) in order to be able to use up-to-date computers not containing a parallel and a serial port. 7. A rod phantom was added in order to make sure the mechanical set-up is of high quality. All these extensions have been implemented in the PTB's BSS 2 model. The routine implementation of extension 1 is still under investigation by the manufacturer. The commercially available BSS 2 will contain extensions 2 to 6 starting approximately in 2012, while extension 7 has already been incorporated since 2011. Extensions 2 to 4 will also be available for old BSS 2 versions via a software update, starting approximately at the beginning of 2012. Extension 6 will be available via hardware change by the manufacturer.

Deviation from Quark Number Scaling of the Anisotropy Parameter v2 of Pions, Kaons, and Protons in Au+Au Collisions at s_NN = 200 GeV  

SciTech Connect

Measurements of the anisotropy parameter v{sub 2} of identified hadrons (pions, kaons, and protons) as a function of centrality, transverse momentum p{sub T}, and transverse kinetic energy KE{sub T} at midrapidity (|{eta}| < 0.35) in Au + Au collisions at {radical}s{sub NN} = 200 GeV are presented. Pions and protons are identified up to p{sub T} = 6 GeV/c, and kaons up to p{sub T} = 4 GeV/c, by combining information from time-of-flight and aerogel Cerenkov detectors in the PHENIX Experiment. The scaling of v{sub 2} with the number of valence quarks (n{sub q}) has been studied in different centrality bins as a function of transverse momentum and transverse kinetic energy. A deviation from previously observed quark-number scaling is observed at large values of KE{sub T}/n{sub q} in noncentral Au + Au collisions (20-60%), but this scaling remains valid in central collisions (0-10%).

Deviation from ?CDM with cosmic strings networks  

NASA Astrophysics Data System (ADS)

In this work, we consider a network of cosmic strings to explain a possible deviation from ?CDM behaviour. We use different observational data to constrain the model and show that a small but non-zero contribution from the string network is allowed by the observational data, which can result in a reasonable departure from ?CDM evolution. But by calculating the Bayesian evidence, we show that the present data still strongly favour the concordance ?CDM model irrespective of the choice of the prior.

Hand deviations away from visual cues: indirect evidence for inhibition.  

PubMed

Previous research has demonstrated that when a stimulus is to be ignored, the path of motion towards a target (saccade or manual reach) deviates away from the to-be-ignored stimulus. Path deviations in saccade and reaching tasks have, however, been observed in very different situations. In the saccade tasks subjects initially attended to a cue, then disengaged attention while saccading to a target. By contrast, in the selective reaching tasks attention was continuously withdrawn from the to-be-ignored stimulus, as this was irrelevant throughout the experiment. In the two experiments reported here, cues similar to those studied in saccade tasks are examined with selective reaching procedures. Experiment 1 shows that when a coloured light-emitting diode cue, upon which subjects engage and then subsequently disengage attention, is close to the responding hand, the hand deviates away from the cue. Experiment 2 confirms this cue avoidance by showing that, compared with central fixation alone, the hand veers away from a central cue. These results confirm that the path deviations observed in saccades can also be obtained in manual reaching movements. Such findings support the notion that eye and hand movements are both affected by inhibitory mechanisms of attention. PMID:9028783

A three-dimensional correction factor equation for deviated wells  

SciTech Connect

The size of a fault cut as determined by log correlation is defined as the true vertical thickness of the missing or repeated section. Likewise, sand thicknesses determined from well logs and used for net sand or net hydrocarbon isopach mapping are also defined in terms of true vertical thickness. Therefore, the size of a fault or the thickness of a sand determined by log correlation with a deviated well, exhibiting a measured log thickness, must be converted to true vertical thickness. The authors have derived a three-dimensional correction factor equation applicable to deviated wells. The equation is used to correct the size of fault cuts for use in fault surface mapping and structure map integration, and the thickness of sand applicable to isopach mapping. This equation is more accurate than any previously published two- or three-dimensional equation. Although two-dimensional equations are simple to use, they lack application in three dimensions. They consider the three-dimensional equation preferable because: (1) this one equation can be used to calculate a correction factor regardless of the direction of wellbore deviation, and (2) the true dip of the beds is used in the equation instead of the apparent dip, which is used in the two-dimensional equations. They introduce a three-dimensional coordinate system, derive the new equation, and illustrate the application of the equation to several deviated wells.

Standard enthalpy of formation of (NO2)2[NiF6](cr)  

NASA Astrophysics Data System (ADS)

The enthalpies of interactions of (NO2)2[NiF6](cr) with water and aqueous KOH, enthalpies of solution of KF(cr) in dilute aqueous solutions of KNO3 and KOH, and enthalpy of mixing of solutions of NiF2, HNO3, and HF were measured at 298.15 K using isothermic-shell calorimeters. Based on the obtained data and values in the literature, the standard enthalpy of formation of the compound under study was determined by two independent methods: ?f H°(NO2)2[NiF6](cr) = -1099 ± 9 kJ/mol.

Follicle deviation and intrafollicular and systemic estradiol concentrations in mares.  

PubMed

By definition, follicle deviation begins on the day the two largest follicles of a wave begin to differ in growth rates. The relationships between follicle deviation and intrafollicular and systemic estradiol concentrations were studied in ponies, using a two-follicle model in which all but the two largest follicles were ablated. A 20-microliter sample of follicular fluid was obtained from each of the two follicles by transvaginal ultrasonography. In experiment 1, the two follicles were sampled when the larger follicle reached 15 mm. No differences (p > 0.05) in post-sampling follicle characteristics were found between control (n = 6) and sampled (n = 8) groups except that the growth rate was slower (p < 0.01) in the larger follicle between the day of sampling and the next day (0.7 +/- 0.7 mm per day) than in the controls (3.3 +/- 0.3 mm per day). The growth rates between 2 and 5 days after sampling were not different between groups. Follicular fluid estradiol-17beta concentrations were higher (p < 0.007) in the larger follicle (460 +/- 67 ng/ml; diameter, 16.4 +/- 0.4 mm) than in the smaller follicle (322 +/- 50 ng/ml; diameter, 14.6 +/- 0.6 mm). In experiment 2, the pair of follicles was sampled when the larger follicle reached 15 mm, 20 mm, or 25 mm (n = 5 per group). There were no significant differences among the three groups for day of deviation and diameters of larger and smaller follicles at deviation. The difference in diameter between the larger and smaller follicles was similar for the 15-mm (2.2 +/- 0.9 mm) and 20-mm (3.1 +/- 1.0 mm) groups, but the difference between follicles for the 25-mm group (7.9 +/- 1.2 mm) was greater (p < 0.004) than for the other two groups. In contrast, the differences in estradiol concentrations between the larger and smaller follicles increased (p < 0.0001) progressively for the 15-mm (13.0 +/- 86.8 ng/ml), 20-mm (722.0 +/- 173.8 ng/ml), and 25-mm (1873.5 +/- 310.3 ng/ml) groups. The first significant (p < 0.007) increase in systemic estradiol occurred between the day before and the day of the beginning of deviation. Detection of an increased difference in estradiol concentrations between the two follicles before the detection of a change in differences in diameter suggests, on a temporal basis, that estradiol is a candidate for involvement in the mechanism that leads to follicle-diameter deviation in mares.

Geodesic deviation equation in Bianchi cosmologies  

NASA Astrophysics Data System (ADS)

We present the Geodesic Deviation Equation (GDE) for the Friedmann Robertson Walker(FRW) universe and we compare it with the equation for Bianchi type I model. We justify consider this cosmological model due to the recent importance the Bianchi Models have as alternative models in cosmology. The main property of these models, solutions of Einstein Field Equations (EFE) is that they are homogeneous as the FRW model but they are not isotropic. We can see this because they have a non-null Weyl tensor, which is zero for FRW model. We study some consequences of this Weyl tensor in the GDE.

A deviation display method for visualising data in mobile gamma-ray spectrometry.  

PubMed

A real time visualisation method, to be used in mobile gamma-spectrometric search operations using standard detector systems is presented. The new method, called deviation display, uses a modified waterfall display to present relative changes in spectral data over energy and time. Using unshielded (137)Cs and (241)Am point sources and different natural background environments, the behaviour of the deviation displays is demonstrated and analysed for two standard detector types (NaI(Tl) and HPGe). The deviation display enhances positive significant changes while suppressing the natural background fluctuations. After an initialization time of about 10min this technique leads to a homogeneous display dominated by the background colour, where even small changes in spectral data are easy to discover. As this paper shows, the deviation display method works well for all tested gamma energies and natural background radiation levels and with both tested detector systems. PMID:20456962

Eccentric eye and head positions in darkness induce deviation from the intended path.  

PubMed

Head and gaze are aligned with the actual path during locomotion. Before a turn is made, gaze changes in the direction of the planned trajectory. We investigated whether eccentric horizontal head and/or eye position without vision causes deviations from the intended straight path. Twenty blindfolded healthy volunteers were asked to walk toward a previously seen target 10 m straight ahead. Various combinations of head and eye positions were tested (eye-in-head gaze straight ahead or 35 degrees left or right with head straight ahead or 70 degrees left or right). Head rotation to the left caused a gait deviation to the right (3.7 degrees ) and head rotation to the right caused a deviation to the left (2.7 degrees ; F(2,40) = 34.966; P < 0.00001). Eye position also showed a tendency to cause gait deviations opposite in direction to gaze, which was, however, not significant. Deviations from the intended straight path were largest with head rotation and eyes straight ahead (gaze 70 degrees off target) or eyes opposite to head rotation (gaze 35 degrees off target). Notably, when lateral eye deviation added to head rotation (gaze 105 degrees off target), i.e., gaze is directed backward, mean deviations decreased (2.3 degrees to the right and 1.2 degrees to the left). Thus, we show that (1) eccentric head positions induce direction-specific gait deviations that are independent of concurrent environmental visual information, and (2) that gait deviations are contraversive to eye-head gaze rather than ipsiversive as reported by others for visually controlled locomotion. The direction of deviation may reflect the compensation of an expected or perceived deviation in the direction of gaze. PMID:16604319

Common standards of basal insulin titration in type 2 diabetes.  

PubMed

Type 2 diabetes mellitus has become a worldwide major health problem, and the number of people affected is steadily increasing. Thus, not all patients suffering from the disease can be treated by specialized diabetes centers or outpatient clinics, but by primary care physicians. The latter, however, might have time constraints and have to deal with many kinds of diseases or with multimorbid patients, so their focus is not so much on lowering high blood glucose values. Thus, the physicians, as well as the patients themselves, are often reluctant to initiate and adjust insulin therapy, although basal insulin therapy is considered the appropriate strategy after oral antidiabetic drug failure, according to the latest international guidelines. A substantial number of clinical studies have shown that insulin initiation and optimization can be managed successfully by using titration algorithms-even in cases where patients themselves are the drivers of insulin titration. Nevertheless, tools and strategies are needed to facilitate this process in the daily life of both primary health care professionals and patients with diabetes. PMID:23759411

Comparing directly measured standard gamble scores to HUI2 and HUI3 utility scores: group- and individual-level comparisons.  

PubMed

Directly measured standard gamble (SG) utility scores reflect the respondent's assessment and valuation of their own health status. Scores from the health utilities index (HUI) are based on self-assessed health status but valued using community preferences obtained using the SG. Our objectives were to find if mean directly measured utility scores agree with mean HUI mark 2 (HUI2) and mean HUI mark 3 (HUI3) scores. Also, if individual directly measured utility scores agree with HUI2 and HUI3 scores, and whether HUI2 and HUI3 scores agree. Questionnaires based on the HUI2 and HUI3 health-status classification systems were administered by interviewers to 140 teenage survivors of extremely low birthweight (ELBW) and 124 control group teens. Respondents were asked to think about their own usual health states using six dimensions from HUI2 and value that state using the SG. Mean SG scores are compared with mean HUI2 and mean HUI3 scores using paired sample t-tests. Mean HUI2 scores are compared with mean HUI3 scores. Agreement among scores is assessed using intra-class correlation coefficient (ICC). The effect of severity of health-state morbidity on agreement was assessed using three approaches. ELBW cohort mean (standard deviation) SG, HUI2, and HUI3 scores were 0.90 (0.20), 0.89 (0.14), and 0.80 (0.22). Results for controls were 0.93 (0.11), 0.95 (0.09), and 0.89 (0.13). Mean SG and HUI2 scores did not differ; mean SG and HUI3 did differ; mean HUI2 and HUI3 also differed. At the individual level for ELBW, the ICCs between SG and HUI2, SG and HUI3, and HUI2 and HUI3 scores were 0.13, 0.28, and 0.64. For controls the ICCs were 0.14, 0.24, and 0.56. HUI2 scores appear to match directly measured utility scores reasonably well at the group level. HUI2 and HUI3 scores differ systematically. At the individual level, however, HUI2 and HUI3 scores are poor substitutes for directly measured scores. PMID:14672594

Meristem temperature substantially deviates from air temperature even in moderate environments: is the magnitude of this deviation species-specific?  

PubMed

Meristem temperature (Tmeristem ) drives plant development but is hardly ever quantified. Instead, air temperature (Tair ) is usually used as its approximation. Meristems are enclosed within apical buds. Bud structure and function may differ across species. Therefore, Tmeristem may deviate from Tair in a species-specific way. Environmental variables (air temperature, vapour pressure deficit, radiation, and wind speed) were systematically varied to quantify the response of Tmeristem . This response was related to observations of bud structure and transpiration. Tomato and cucumber plants were used as model plants as they are morphologically distinct and usually growing in similar environments. Tmeristem substantially deviated from Tair in a species-specific manner under moderate environments. This deviation ranged between -2.6 and 3.8?°C in tomato and between -4.1 and 3.0?°C in cucumber. The lower Tmeristem observed in cucumber was linked with the higher transpiration of the bud foliage sheltering the meristem when compared with tomato plants. We here indicate that for properly linking growth and development of plants to temperature in future applications, for instance in climate change scenarios studies, Tmeristem should be used instead of Tair , as a species-specific trait highly reliant on various environmental factors.

An International Collaboration To Standardize HIV-2 Viral Load Assays: Results from the 2009 ACHIEV2E Quality Control Study?  

PubMed Central

Accurate HIV-2 plasma viral load quantification is crucial for adequate HIV-2 patient management and for the proper conduct of clinical trials and international cohort collaborations. This study compared the homogeneity of HIV-2 RNA quantification when using HIV-2 assays from ACHIEV2E study sites and either in-house PCR calibration standards or common viral load standards supplied to all collaborators. Each of the 12 participating laboratories quantified blinded HIV-2 samples, using its own HIV-2 viral load assay and standard as well as centrally validated and distributed common HIV-2 group A and B standards (http://www.hiv.lanl.gov/content/sequence/HelpDocs/subtypes-more.html). Aliquots of HIV-2 group A and B strains, each at 2 theoretical concentrations (2.7 and 3.7 log10 copies/ml), were tested. Intralaboratory, interlaboratory, and overall variances of quantification results obtained with both standards were compared using F tests. For HIV-2 group A quantifications, overall and interlaboratory and/or intralaboratory variances were significantly lower when using the common standard than when using in-house standards at the concentration levels of 2.7 log10 copies/ml and 3.7 log10 copies/ml, respectively. For HIV-2 group B, a high heterogeneity was observed and the variances did not differ according to the type of standard used. In this international collaboration, the use of a common standard improved the homogeneity of HIV-2 group A RNA quantification only. The diversity of HIV-2 group B, particularly in PCR primer-binding regions, may explain the heterogeneity in quantification of this strain. Development of a validated HIV-2 viral load assay that accurately quantifies distinct circulating strains is needed.

PILOT STUDY: International comparison CCQM-P41 Greenhouse gases. 2. Direct comparison of primary standard gas mixtures  

NASA Astrophysics Data System (ADS)

In this second part of this study, primary standard gas mixtures (PSMs) as used for calibrations for the greenhouse gases carbon dioxide and methane have been compared. The nominal amount-of-substance fraction levels were 365 µmol/mol for carbon dioxide and 1.8 µmol/mol for methane. The matrix was synthetic air, simulated by a mixture of nitrogen, oxygen (209 mmol/mol) and argon (9.3 mmol/mol). The measurements took place in the spring of 2003. In the protocol, it was foreseen to have the PSMs produced for this study in a small range, enabling regression analysis on the data to assess the consistency of the gas mixtures. The direct comparison of the PSMs shows agreement for carbon dioxide at 365 µmol/mol nominal within 0.52 µmol/mol (0.14% relative) standard uncertainty. One cylinder lies between the 95% and 99% boundaries of the regression line, and after removing this cylinder from the dataset the standard deviation of the x-residuals reduces to 0.18 µmol/mol (0.05% relative). This value for the standard deviation is substantially greater than the stated standard uncertainties for several cylinders. The standard deviation of the x-residuals for methane at 1.8 µmol/mol nominal is 0.011 µmol/mol. Main text. To reach the main text of this paper, click on Final Report. The final report has been peer-reviewed and approved for publication by the CCQM.

Inspirational airflow patterns in deviated noses: a numerical study.  

PubMed

This study attempts to evaluate the effects of deviation of external nose to nasal airflow patterns. Four typical subjects were chosen for model reconstruction based on computed tomography images of undeviated, S-shaped deviated, C-shaped deviated and slanted deviated noses. To study the hypothetical influence of deviation of external nasal wall on nasal airflow (without internal blockage), the collapsed region along the turbinate was artificially reopened in all the three cases with deviated noses. Computational fluid dynamics simulations were carried out in models of undeviated, original deviated and reopened nasal cavities at both flow rates of 167 and 500 ml/s. The shape of the anterior nasal roof was found to be collapsed on one side of the nasal airways in all the deviated noses. High wall shear stress region was found around the collapsed anterior nasal roof. The nasal resistances in cavities with deviated noses were considerably larger than healthy nasal cavity. Patterns of path-line distribution and wall shear stress distribution were similar between original deviated and reopened models. In conclusion, the deviation of an external nose is associated with the collapse of one anterior nasal roof. The crooked external nose induced a larger nasal resistance compared to the undeviated case, while the internal blockage of the airway along the turbinates further increased it. PMID:22515677

MUSiC - An Automated Scan for Deviations between Data and Monte Carlo Simulation  

SciTech Connect

A model independent analysis approach is presented, systematically scanning the data for deviations from the standard model Monte Carlo expectation. Such an analysis can contribute to the understanding of the CMS detector and the tuning of event generators. The approach is sensitive to a variety of models of new physics, including those not yet thought of.

Spine deviations and orthodontic treatment of asymmetric malocclusions in children  

PubMed Central

Background The aim of this randomized clinical trial was to assess the effect of early orthodontic treatment for unilateral posterior cross bite in the late deciduous and early mixed dentition using orthopedic parameters. Methods Early orthodontic treatment was performed by initial maxillary expansion and subsequent activator therapy (Münster treatment concept). The patient sample was initially comprised of 80 patients with unilateral posterior cross bite (mean age 7.3?years, SD 2.1?years). After randomization, 77 children attended the initial examination appointment (therapy?=?37, control?=?40); 31 children in the therapy group and 35 children in the control group were monitored at the follow-up examination (T2). The mean interval between T1 and T2 was 1.1?years (SD 0.2?years). Rasterstereography was used for back shape analysis at T1 and T2. Using the profile, the kyphotic and lordotic angle, the surface rotation, the lateral deviation, pelvic tilt and pelvic torsion, statistical differences at T1 and T2 between the therapy and control groups were calculated (t-test). Our working hypothesis was, that early orthodontic treatment can induce negative therapeutic changes in body posture through thoracic and lumbar position changes in preadolescents with uniltaral cross bite. Results No clinically relevant differences between the control and the therapy groups at T1 and T2 were found for the parameters of kyphotic and lordotic angle, the surface rotation, lateral deviation, pelvic tilt, and pelvic torsion. Conclusions Our working hypothesis was tested to be not correct (within the limitations of this study). This randomized clinical trial demonstrates that in a juvenile population with unilateral posterior cross bite the selected early orthodontic treatment protocol does not affect negatively the postural parameters.

The relationship between middle ear pressure and deviated nasal septum.  

PubMed

The deviated nasal septum may be associated with middle ear problems, particularly on the side of nasal obstruction. This study aims to find out whether middle ear pressure (MEP) correlates with the degree of nasal obstruction secondary to a deviated nasal septum, and to examine changes in MEP following septal surgery. Patencies of the nasal passages (measured with a peak nasal inspiratory flowmeter) and MEP (measured with a tympanometer) of 55 patients were obtained prior to surgery and 7.5 (6-10) months post-operatively [median (range)]. Forty patients completed the study. Results were analysed by linear regression. In the ear on the side of nasal blockage, MEP was -25.7 +/- 28.4 mm water pre-operatively, and following surgery increased significantly to -2.9 +/- 30.4 mm water (mean +/- SD) (P < 0.001). Pre-operatively, it was inversely related to the difference in patencies between the two nasal passages (r = -0.32, P < 0.02). Post-operatively, its improvement correlated with the degree of reduction of asymmetry of airway patency (r = 0.56, P < 0.001). PMID:8877192

Physical interpretation of Kundt spacetimes using geodesic deviation  

NASA Astrophysics Data System (ADS)

We investigate the fully general class of non-expanding, non-twisting and shear-free D-dimensional geometries using the invariant form of geodesic deviation equation which describes the relative motion of free test particles. We show that the local effect of such gravitational fields on the particles basically consists of isotropic motion caused by the cosmological constant ?, Newtonian-type tidal deformations typical for spacetimes of algebraic type D or II, longitudinal motion characteristic for spacetimes of type III, and type N purely transverse effects of exact gravitational waves with D(D ? 3)/2 polarizations. We explicitly discuss the canonical forms of the geodesic deviation motion in all algebraically special subtypes of the Kundt family for which the optically privileged direction is a multiple Weyl aligned null direction, namely D(a), D(b), D(c), D(d), III(a), III(b), IIIi, IIi, II(a), II(b), II(c) and II(d). We demonstrate that the key invariant quantities determining these algebraic types and subtypes also directly determine the specific local motion of test particles, and are thus measurable by gravitational detectors. As an example, we analyze an interesting class of type N or II gravitational waves which propagate on backgrounds of type O or D, including Minkowski, Bertotti–Robinson, Nariai and Pleba?ski–Hacyan universes.

Two-dimensional magnetic sensitivity to asymmetric and symmetric deviations for SSC quadrupole magnets  

NASA Astrophysics Data System (ADS)

The magnetic multipole sensitivity to asymmetric and symmetric deviations is analyzed in the two-dimensional cross-section of SSC quadrupole magnets. Deviations in the 2-D cross-section caused by variations in the superconducting cable locations due to changes in the thickness of the pole sheet, mid plane insulation, inter-layer spacer, backing sheet, and copper wedges have direct impact on the magnetic field gradient and multipoles in the straight section of the magnets. Asymmetric deviations due to different coil sizes in a cross-section are also analyzed. The analyses are performed mainly with the software package AHARM(1). SSCMAG(1) and finite element software PE2D(2) were also used to obtain baselines and to verify the results. The results provide information essential to an understanding of the deviations of the multipoles resulting from manufacturing processes, and suggest possibilities for tuning the multipoles to meet the magnetic requirements.

Catalytic oxidation of H2 on platinum: a robust method for generating low mixing ratio H2O standards  

NASA Astrophysics Data System (ADS)

Standard reference samples of water vapor suitable for in situ calibration of atmospheric hygrometers are not currently widespread, leading to difficulties in unifying the calibrations of these hygrometers and potentially contributing to observed measurement discrepancies. We describe and evaluate a system for reliably and quantitatively converting mixtures of H2 in air to H2O on a heated platinum surface, providing a compact, portable, adjustable source of water vapor. The technique is shown to be accurate and can be used to easily and reliably produce a wide range of water vapor concentrations (?1 ppm -2%) on demand. The result is a H2O standard that is expected to be suitable for in situ calibration of aircraft hygrometers, with an accuracy nearly that of the available H2 standards (?±2%).

Cosmic expansion and deviations from it

Questions related to the reality of cosmic expansion are addressed. Distance determinations of field galaxies and clusters and distance indicators are examined. Particular consideration is given to the determinations of the value of the Hubble constant and to distance indicators to the Virgo cluster. Unreliable distance indicators, such as the brightest stars in the K- and K-band, planetary nebulae, and surface brightness fluctuations, are identified. It is concluded that the asymptotic value of the Hubble constant is H0 (cosmic) = 55 +/-2. Higher values in the literature are caused by a fallacious distance indicator and/or the sample selection effect.

WaterML2.0: Harmonising standards for water observations data  

NASA Astrophysics Data System (ADS)

Our ability to share and understand water information from various sources is currently limited by the use of incompatible information management and publication technologies. Water resource managers, hydro-power generators, meteorologists and other interested stakeholders all monitor water resources and store their data using a wide array of technologies. Standards are multi-party agreements that provide a common ground on which people can share information by minimising ambiguity and sharing definitions for domain concepts. They are most effective when surrounded by an active community who, along with taking part in defining such concepts, develop supporting tools that allow for easy transmission and interpretation of data sets. Existing standards for water observations only exist within organisations or countries; there are no internationally agreed upon standards for encoding such data. Groups such as the Consortium of Universities for the Advancement of Hydrological Sciences, the Australian Bureau of Meteorology, and others, have developed standards for national exchange of water information, such as WaterML1.1 and the Water Data Transfer Format; other standards such as Xhydro have been developed at the sub national level. An initial analysis of existing standards (including WaterML1.1, WDTF, XHydro and the UK EA format) found sufficient commonality to suggest a role for an international standard. Such a standard would reduce the load on organisations developing their own standards. The commonalities exist in the way in which measurements and observations are made and described, such as time series data produced from automated sensors commonly used for hydrological monitoring. The Observations and Measurements (O&M) standard, developed by the Open Geospatial Consortium (OGC), is capable of describing measurements made by sensors and humans in a common way, involving both remote and in-situ sensing. O&M is generic, in that it does not define the concepts for a particular domain such as hydrology, but rather the abstract components that are needed when making observations: features, observed properties of features, observation procedures and results. By making use of the O&M standard and specialising it with harmonised definitions of water observation concepts, it is proposed that a domain-level standard, WaterML2.0, be developed. It would be capable of precisely describing the relevant aspects of hydrological observations. Re-using existing standards suites, such as OGC, allows the development to focus on capturing domain specific concepts without redefining common types such as spatial types, standard data structures and so on. The development will be done by involving key stakeholders who have developed existing standards and understand hydrological observational practices. Through the Hydrology Domain Working Group within OGC, jointly chaired by the OGC and the World Meteorological Organization (WMO), WaterML2.0 will be developed as an OGC standard. It may then be leveraged by existing web services, such as the OGC's Sensor Observation Service (SOS), to query and extract water information across the Internet using common tools. This will allow water information to be shared - and most importantly understood - by a much wider audience.

Mercury exposure as a model for deviation of cytokine responses in experimental Lyme arthritis: HgCl2 treatment decreases T helper cell type 1-like responses and arthritis severity but delays eradication of Borrelia burgdorferi in C3H/HeN mice  

PubMed Central

Lyme borreliosis is a complex infection, where some individuals develop so-called ‘chronic borreliosis’. The pathogenetic mechanisms are unknown, but the type of immune response is probably important for healing. A strong T helper cell type 1 (Th1)-like response has been suggested as crucial for eradication of Borrelia and for avoiding development of chronic disease. Many studies aimed at altering the Th1/Th2 balance in Lyme arthritis employed mice deficient in cytokine genes, but the outcome has not been clear-cut, due possibly to the high redundancy of cytokines. This study aimed at studying the importance of the Th1/Th2 balance in murine Borrelia arthritis by using the Th2-deviating effect of subtoxic doses of inorganic mercury. Ninety-eight C3H/HeN mice were divided into four groups: Borrelia-infected (Bb), Borrelia-infected exposed to HgCl2 (BbHg), controls exposed to HgCl2 alone and normal controls. Mice were killed on days 3, 16, 44 and 65 post-Borrelia inoculation. Arthritis severity was evaluated by histology, spirochaetal load determined by Borrelia culture, IgG2a- and IgE-levels analysed by enzyme-linked immunosorbemt assay (ELISA) and cytokine-secreting cells detected by enzyme-linked immunospot (ELISPOT). BbHg mice showed less severe histological arthritis, but delayed eradication of spirochaetes compared to Bb mice, associated with increased levels of IgE (Th2-induced) and decreased levels of IgG2a (Th1-induced), consistent with a Th2-deviation. Both the numbers of Th1 and Th2 cytokine-secreting cells were reduced in BbHg mice, possibly explained by the fact that numbers of cytokine-secreting cells do not correlate with cytokine concentration. In conclusion, this study supports the hypothesis that a Th1-like response is required for optimal eradication of Borrelia.

Characterization of a Recombinant Adeno-Associated Virus Type 2 Reference Standard Material  

PubMed Central

Abstract A recombinant adeno-associated virus serotype 2 Reference Standard Material (rAAV2 RSM) has been produced and characterized with the purpose of providing a reference standard for particle titer, vector genome titer, and infectious titer for AAV2 gene transfer vectors. Production and purification of the reference material were carried out by helper virus–free transient transfection and chromatographic purification. The purified bulk material was vialed, confirmed negative for microbial contamination, and then distributed for characterization along with standard assay protocols and assay reagents to 16 laboratories worldwide. Using statistical transformation and modeling of the raw data, mean titers and confidence intervals were determined for capsid particles ({X}, 9.18?×?1011 particles/ml; 95% confidence interval [CI], 7.89?×?1011 to 1.05?×?1012 particles/ml), vector genomes ({X}, 3.28?×?1010 vector genomes/ml; 95% CI, 2.70?×?1010 to 4.75?×?1010 vector genomes/ml), transducing units ({X}, 5.09?×?108 transducing units/ml; 95% CI, 2.00?×?108 to 9.60?×?108 transducing units/ml), and infectious units ({X}, 4.37?×?109 TCID50 IU/ml; 95% CI, 2.06?×?109 to 9.26?×?109 TCID50 IU/ml). Further analysis confirmed the identity of the reference material as AAV2 and the purity relative to nonvector proteins as greater than 94%. One obvious trend in the quantitative data was the degree of variation between institutions for each assay despite the relatively tight correlation of assay results within an institution. This relatively poor degree of interlaboratory precision and accuracy was apparent even though attempts were made to standardize the assays by providing detailed protocols and common reagents. This is the first time that such variation between laboratories has been thoroughly documented and the findings emphasize the need in the field for universal reference standards.

A voluntary standard for 3.2 mm unipolar and bipolar pacemaker leads and connectors.  

PubMed

In response to concerns over proliferation of new and different technologies in leads and lead connectors, a voluntary standard for 3.2 mm unipolar and bipolar pacemaker leads and connectors has been established. One major difficulty overcome in the process was the design of the voluntary standard. The greatest controversy centers around the design for the sealing mechanism for the connection of the pacemaker to the leads. Some suggest that the sealing mechanism should be in the form of seal rings on the lead; others believe that it is preferable to have the seal rings inside the pacemaker cavity. The new voluntary standard finally agreed upon represents a compromise position. It is a standard that appeals to future development since it favors leads smaller than those in current distribution, and provides for backward compatibility with existing leads. In addition, it allows each manufacturer as much design flexibility as possible. It is hoped that this voluntary standard will be universally accepted throughout the industry. PMID:2432529

Reflected beam's direction deviation induced by the corner cube retroreflector  

NASA Astrophysics Data System (ADS)

The direction deviation of the reflected beam induced by the corner cube retroreflector (CCR) is respectively discussed by geometrical optics approach and the principle of physical optics in this paper. A mathematical model was built to calculate the beam's aberration due to the fabrication errors of the CCR. It can be concluded that the centroid direction error of far field spot is much more appropriate to describe the reflection beam's direction deviation for a broad incident beam, and the beam with even intensity distribution should be used to reduce its direction deviation.

Validation for 2D/3D registration I: A new gold standard data set  

SciTech Connect

Purpose: In this article, the authors propose a new gold standard data set for the validation of two-dimensional/three-dimensional (2D/3D) and 3D/3D image registration algorithms. Methods: A gold standard data set was produced using a fresh cadaver pig head with attached fiducial markers. The authors used several imaging modalities common in diagnostic imaging or radiotherapy, which include 64-slice computed tomography (CT), magnetic resonance imaging using Tl, T2, and proton density sequences, and cone beam CT imaging data. Radiographic data were acquired using kilovoltage and megavoltage imaging techniques. The image information reflects both anatomy and reliable fiducial marker information and improves over existing data sets by the level of anatomical detail, image data quality, and soft-tissue content. The markers on the 3D and 2D image data were segmented using ANALYZE 10.0 (AnalyzeDirect, Inc., Kansas City, KN) and an in-house software. Results: The projection distance errors and the expected target registration errors over all the image data sets were found to be less than 2.71 and 1.88 mm, respectively. Conclusions: The gold standard data set, obtained with state-of-the-art imaging technology, has the potential to improve the validation of 2D/3D and 3D/3D registration algorithms for image guided therapy.

Prevalence of Nasal Septal Deviation in New-borns and Its Precipitating Factors: A Cross-Sectional Study.  

PubMed

To estimate the prevalence of neonatal nasal septal deviation and to identify the precipitating factors. 250 neonates were examined on the 2nd day using Gray's struts for the presence of deviated nasal septum. Struts passing up to the 4 cm mark was taken to be normal, while struts getting stuck before the 4 cm mark was diagnosed to have deviated septum on that particular side. Out of 250 neonates, 49 had nasal septal deviation. There was significantly higher number of deviations in neonates of primiparas, emergency LSCS and in high birth weight babies. Neonatal septal deviation is quite common, being present in approximately 20% of all newborns. Greater amount of birth trauma increases its incidence further. PMID:23998029

Spin-geodesic deviations in the Schwarzschild spacetime  

NASA Astrophysics Data System (ADS)

The deviation of the path of a spinning particle from a circular geodesic in the Schwarzschild spacetime is studied by an extension of the idea of geodesic deviation. Within the Mathisson-Papapetrou-Dixon model and assuming the spin parameter to be sufficiently small so that it makes sense to linearize the equations of motion in the spin variables as well as in the geodesic deviation, the spin-curvature force adds an additional driving term to the second order system of linear ordinary differential equations satisfied by nearby geodesics. Choosing initial conditions for geodesic motion leads to solutions for which the deviations are entirely due to the spin-curvature force, and one finds that the spinning particle position for a given fixed total spin oscillates roughly within an ellipse in the plane perpendicular to the motion, while the azimuthal motion undergoes similar oscillations plus an additional secular drift which varies with spin orientation.

Standard technical specifications, Westinghouse Plants: Bases (Sections 2.0--3.3). Volume 2, Revision 1  

SciTech Connect

This NUREG contains the improved Standard Technical Specifications (STS) for Westinghouse plants. Revision 1 incorporates the cumulative changes to Revision 0, which was published in September 1992. The changes reflected in Revision 1 resulted from the experience gained from license amendment applications to convert to these improved STS or to adopt partial improvements to existing technical specifications. This NUREG is the result of extensive public technical meetings and discussions between the Nuclear Regulatory Commission (NRC) staff and various nuclear power plant licensees, Nuclear Steam Supply System (NSSS) Owners Groups, specifically the Westinghouse Owners Group (WOG), NSSS vendors, and the Nuclear Energy Institute (NEI). The improved STS were developed based on the criteria in the Final Commission Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors, dated July 22, 1993 (58 FR 39132). Licensees are encouraged to upgrade their technical specifications consistent with those criteria and conforming, to the extent practical and consistent with the licensing basis for the facility, to Revision 1 to the improved STS. The Commission continues to place the highest priority on requests for complete conversions to the improved STS. Licensees adopting portions of the improved STS to existing technical specifications should adopt all related requirements, as applicable, to achieve a high degree of standardization and consistency.

Soliton propagation in a dispersion map with deviation from periodicity  

NASA Astrophysics Data System (ADS)

Solitons in dispersion-managed fibers are a particular case of a periodically perturbed nonlinear system. Since in practice random deviations from strict periodicity of the dispersion alternation are unavoidable, we consider such deviations and study their impact on the soliton’s stability with a view to optical telecommunications. We find a range over which solitons remain stable in a specified sense; this range is sufficient for technical application.

Nasal septal deviation in the pediatric and adult populations.  

PubMed

A significant proportion of the population has nasal septal deviation of varying degrees. Recent reports of such deviation occurring at younger ages suggest a congenital etiology. To the best of our knowledge, no previous clinical studies have compared the septal deviation of adult and pediatric populations with a uniform measure that focuses on the degree of deviation. We retrospectively analyzed computed tomography (CT) and magnetic resonance imaging (MRI) scans obtained from 81 patients who had undergone head and neck imaging for a variety of reasons. These subjects were divided into four age groups: younger than 4 months; 4 months to less than 5 years; 5 to 15 years; and more than 15 years. We used a measure of tortuosity to examine and compare nasal septal deviation among the different age groups. The tortuosity of the septum was measured at four precise points along the length of the septum on thin-section sinus CT and MRI. Tortuosity was defined as the ratio of the "actual" length of the septum to the "ideal" length of the septum, which was defined as the length of a straight line drawn from the superior to the inferior aspect of the septum. We found that subjects younger than 5 years of age exhibited significantly less tortuosity (p ? 0.017459) than did the older children and the adults. Therefore, we conclude that nasal septal deviation occurs at a higher frequency in older children and in adults when calculations of tortuosity are used as a measure. Our data may suggest that a noncongenital etiology is responsible for nasal septal deviation. However, given that the growth of the septum continues throughout childhood, our results do not preclude the possibility of a genetic predisposition to the later development of a deviated nasal septum.

The effect of nasal septal deviation on maxillary sinus volumes and development of maxillary sinusitis.  

PubMed

OBJECTIVES: The purpose of this study was to determine the possible role of nasal septal deviation on volume of maxillary sinuses and its relationship with development of maxillary sinusitis. MATERIALS AND METHODS: Between May 2010 and September 2012, paranasal sinus computed tomography (CT) findings of 825 patients (470 males, 355 females), who admitted to Ear Nose and Throat Department of Bozok University Medical Faculty were retrospectively analyzed. By excluding the other co-existent sino nasal pathologies, 109 consecutive patients (47 males, 62 females mean age 36 ± 13.4 years; range 18-71 years) with isolated nasal septal deviations were recruited for the study. The convex side of the septal curvature was accepted as the direction of deviation. The findings were grouped according to the radiologically measured angle of nasal septal deviations. The deviation angle of the nasal septum was described as; mild (<9°), moderate (the angle between 9° and 15°), or severe (15° and up). The volume of each maxillary sinus (ipsi- and contralateral to the deviation side) was also calculated using the computer program. Sinusitis was defined as any evident thickening of the maxillary sinus mucosa. RESULTS: There were 62 females and 47 males with a mean age of 36 ± 13.4. Nasal septal deviation angles were found to range between 5° and 27.2° (mean 13° ± 3.4°). The right sided deviations included 19 mild (<9°, Group I), 16 moderate (9°-15°, Group II), and 16 severe (15° and up, Group III) cases. The left sided deviations included 19 mild (<9°, Group I), 19 moderate (9°-15°, Group II), and 20 severe (15° and up, Group III) subjects. Maxillary sinus volumes were compared between right and left sided deviation groups. We could not demonstrate a statistically significant difference between the right maxillary sinus volumes of Groups I and II in left sided deviation cases (p = 0.77). In the same side, comparison of Groups I-III and Groups II-III, the maxillary sinus volume differences were found to be significantly meaningful (p = 0.001 and p = 0.013, respectively). Identical results were yielded in the right sided septal deviation group related to the maxillary sinus volumes of Groups I and II and Groups I-III and Groups II-III compartments (p = 0.99, p = 0.004 and p = 0.003, respectively). In both right and left deviation groups, ipsi and contralateral maxillary sinus volume comparements produced statistically significant results (p = 0.002 and p = 0.04, respectively). The presence of maxillary sinusitis findings were significantly increased in both group (p = 0.00). Statistical significance was set at p < 0.05. CONCLUSION: Our findings suggest that maxillary sinus volumes tend to be higher at the contralateral side of the severe septum deviations. In addition, the chance of finding maxillary sinusitis findings on ipsilateral to the severe septum deviation was significantly increased. PMID:23512432

Results of stress-oriented and aligned perforating in fracturing deviated wells  

SciTech Connect

This paper reports the first results of stress-oriented and aligned perforation of deviated wells at the Kuparuk River field, Alaska. Preferred perforation alignment and spacing are calculated for each well so the fractures from individual perforations link to produce a single zipper fracture plane along the deviated wellbore. Results of the first application of this technique are presented from the 26-well development of Drillsite 2K. The results from use of three different oriented-casing-gun systems and pertinent data from Drillsite 2K fracture stimulation treatments are discussed. Comparisons to drillsite where nonaligned perforating strategies were used show a significant reduction in perforation friction, enabling the placement of large, more productive fracture treatments. Application of this technique to deviated and vertical wells and its use at Kuparuk on developments after Drillsite 2K are discussed.

[Surgical treatment of nasal septal deviation (septoplasty) in children].  

PubMed

The aim of this study was to indicate the importance of surgical treatment of nasal septal deviation in children as early correction of functional and cosmetic nose deformities. In this study, we presented 76 children, from age of 7 to 15, who were surgical treated for the reason of nasal septal deviation starting from January 2001. to December 2009. There were 48 (63%) male and 28 (37%) female patients. The lowest number of patients were between 7 and 9 years old--5 (6.5%), between 10 and 12 years--28 (37%) and 43--(56.5%) between 13 and 15 years. Only 7 (9%) patients indicated genetics inheritance, and 11 of them (14%) could not determine the exact cause of deviation origin. References taken from the parents showed that nasal septal deviation developed like consequence of injury in 58 (76%) cases. We used closed technique of septoplasty with hemitransfictional incision and sub mucosal resection. Deviated portion of septum was completely removed. Patients felt improvement in nose breathing in 65 (85%) cases. The most often complication was nasal obstruction in 6 (8%) cases which occurred due to the insufficient removal of deviated portion. We also had a septal perforation in one and abscess of nasal septum in another case. There were no esthetic deformities.Surgical treatment of nasal septal deviation in children must to be conservative and limited on injured part of septum. After the operation nose breathing significantly improved, without consequences on esthetic appearance or the growth of central part of a face. PMID:22369019

Typical and large-deviation properties of minimum-energy paths on disordered hierarchical lattices  

NASA Astrophysics Data System (ADS)

We perform numerical simulations to study the optimal path problem on disordered hierarchical graphs with effective dimension d eff ? 2.32. Therein, edge energies are drawn from a disorder distribution that allows for positive and negative energies. This induces a behavior which is fundamentally different from the case where all energies are positive, only. Upon changing the subtleties of the distribution, the scaling of the minimum energy path length exhibits a transition from self-affine to self-similar. We analyze the precise scaling of the path length and the associated ground-state energy fluctuations in the vicinity of the disorder critical point, using a decimation procedure for huge graphs. Further, using an importance sampling procedure in the disorder we compute the negative-energy tails of the ground-state energy distribution up to 12 standard deviations away from its mean. We find that the asymptotic behavior of the negative-energy tail is in agreement with a Tracy-Widom distribution. Further, the characteristic scaling of the tail can be related to the ground-state energy flucutations, similar as for the directed polymer in a random medium.

Large Deviation Theorems Revisited: Information-Spectrum Approach  

NASA Astrophysics Data System (ADS)

In this paper we show some new look at large deviation theorems from the viewpoint of the information-spectrum (IS) methods, which has been first exploited in information theory, and also demonstrate a new basic formula for the large deviation rate function in general, which is expressed as a pair of the lower and upper IS rate functions. In particular, we are interested in establishing the general large deviation rate functions that are derivable as the Fenchel-Legendre transform of the cumulant generating function. The final goal is to show, under some mild condition, a necessary and sufficient condition for the IS rate function to be derivable as the Fenchel-Legendre transform of the cumulant generating function, i. e., to be a rate function of Gärtner-Ellis type.

Spin-geodesic deviations in the Kerr spacetime  

NASA Astrophysics Data System (ADS)

The dynamics of extended spinning bodies in the Kerr spacetime is investigated in the pole-dipole particle approximation and under the assumption that the spin-curvature force only slightly deviates the particle from a geodesic path. The spin parameter is thus assumed to be very small and the back reaction on the spacetime geometry neglected. This approach naturally leads to solve the Mathisson-Papapetrou-Dixon equations linearized in the spin variables as well as in the deviation vector, with the same initial conditions as for geodesic motion. General deviations from generic geodesic motion are studied, generalizing previous results limited to the very special case of an equatorial circular geodesic as the reference path.

There Is No Structural Relationship between Nasal Septal Deviation, Concha Bullosa, and Paranasal Sinus Fungus Balls  

PubMed Central

This study aims to determine the relationship between nasal septal deviation, concha bullosa, and chronic rhinosinusitis by using a definitive pathological and simplified model. Fifty-two consecutive sinus computed tomography scans were performed on patients who received endoscopic sinus surgery and whose final diagnosis was paranasal sinus fungus balls. The incidences of nasal septal deviation and concha bullosa for patients diagnosed with paranasal sinus fungus balls among the study group were 42.3% and 25%, respectively. About 63.6% sinuses with fungus balls were located on the ipsilateral side of the nasal septal deviation, and 46.2% were located on the ipsilateral side of the concha bullosa. When examined by Pearson's chi-square test and the chi-squared goodness-of-fit test, no significant statistical difference for the presence of paranasal sinus fungus balls between ipsilateral and contralateral sides of nasal septal deviation and concha bullosa was noted (P = 0.292 and P = 0.593, resp.). In conclusion, we could not demonstrate any statistically significant correlation between the location of infected paranasal sinus, the direction of nasal septal deviation, and the location of concha bullosa, in location-limited rhinosinusitis lesions such as paranasal sinus fungal balls. We conclude that the anatomical variants discussed herein do not predispose patients to rhinosinusitis.

EBSD study of angular deviations from the Goss component in grain-oriented electrical steels.  

PubMed

The magnetic properties of grain-oriented (GO) electrical steels strongly depend on the distribution of the ? and ? angles, i.e., the deviations of the easy magnetisation ?100? from the rolling direction (RD) in the rolling plane and out of the rolling plane, respectively. However, most Electron Backscatter Diffraction (EBSD) studies consider the standard Goss deviation angle, which includes the rotation of the (110) plane about the RD. Therefore, in the present work, a new procedure is demonstrated for deriving the ? and ? angles from EBSD mappings to obtain a quantitative texture characterisation in line with the magnetic properties. This procedure is later applied to 37 GO steels after secondary recrystallisation that exhibit a wide range of permeability levels. The relation between the texture and the polarisation at 800A/m (J800) that is measured in the present study by EBSD is compared to the one that has been determined in previous papers with optical goniometers and X-ray diffraction techniques, and this relation is subsequently used to define a relevant parameter to describe the orientation quality of the grains. The results indicate that the average angle of the ? and ? deviations is a relevant deviation parameter for the characterisation of grain orientations. Finally, it is demonstrated that the combination of the quantitative correlation between polarisation and texture with the orientation imaging of EBSD offers the possibilities of both studying the crystallographic environment of highly oriented grains in the primary recrystallised matrix for the production of high-permeability steels and evaluating the spatial distribution of the angular deviations in GO steels after secondary recrystallisation.

UCRLDetermination of the standard deviation on multiplication based on count distributions  

SciTech Connect

The multiplication M of a multiplying object can be determined by analyzing the arrival times of thermal neutrons in detectors such as helium tubes. A source emitting neutrons randomly will lead to neutron inter arrival times obeying Poisson process statistics. By observing how the inter arrival times of detected counts differ from Poisson statistics, one can assess properties of the neutron source such as the source intensity and multiplication. While the method of analyzing the inter arrival times of neutrons using count distributions to determine characteristics of the source has been used for a long time, the treatment of the errors on the determined quantities multiplication M and source strength S have not yet been adequately treated. This object of this report is to assess these errors.

Doppler standard deviation imaging for clinical monitoring of in vivo human skin blood flow

We used a novel phase-resolved optical Doppler tomographic (ODT) technique with very high flow-velocity sensitivity (10 {mu}m/s) and high spatial resolution (10 {mu}m) to image blood flow in port-wine stain (PWS) birthmarks in human skin. In addition to the regular ODT velocity and structural images, we use the variance of blood flow velocity to map the PWS vessels. Our device combines ODT and therapeutic systems such that PWS blood flow can be monitored in situ before and after laser treatment. To the authors' knowledge this is the first clinical application of ODT to provide a fast semiquantitative evaluation of the efficacy of PWS laser therapy in situ and in real time.

Constant deviation condition performing scanning energy by the rotation of grating around itself is the one of the most practical mounting for grating monochromators. Conventional multilayer coating can obtain high diffraction efficiency merely in a narrow band width. It is found that a new modified multilayer structure on the laminar-type grating intended to enhance the diffraction efficiency for constant deviation condition shows the diffraction efficiency over 5% in a wide band range of 1.5-2.5 keV in calculation.

Determination of absorbed dose to water for high-energy photon and electron beams-comparison of the standards DIN 6800-2 (1997), IAEA TRS 398 (2000) and DIN 6800-2 (2006)  

PubMed Central

For the determination of the absorbed dose to water for high-energy photon and electron beams the IAEA code of practice TRS-398 (2000) is applied internationally. In Germany, the German dosimetry protocol DIN 6800-2 (1997) is used. Recently, the DIN standard has been revised and published as Draft National Standard DIN 6800-2 (2006). It has adopted widely the methodology and dosimetric data of the code of practice. This paper compares these three dosimetry protocols systematically and identifies similarities as well as differences. The investigation was done with 6 and 18 MV photon as well as 5 to 21 MeV electron beams. While only cylindrical chambers were used for photon beams, measurements of electron beams were performed using cylindrical as well as plane-parallel chambers. The discrepancies in the determination of absorbed dose to water between the three protocols were 0.4% for photon beams and 1.5% for electron beams. Comparative measurements showed a deviation of less than 0.5% between our measurements following protocol DIN 6800-2 (2006) and TLD inter-comparison procedure in an external audit.

Biosimilars 2.0: guiding principles for a global "patients first" standard.  

PubMed

In the European Union, biosimilar products have been approved since 2006 under an abbreviated pathway that leverages their similarity to an existing "reference" biological product. The products approved to date are based on recombinant versions of endogenous proteins with well-understood structures and pharmacology, but complicated safety and immunogenicity profiles. The period during the 2000s that included the first reviews, approvals, sale and use of biosimilars, is referred to herein as "Biosimilars 1.0." Over the next several years, a new and advanced tranche of biosimilars will be developed for complex reference products, including medicines used in the treatment of cancer and autoimmune diseases. A global market for biosimilars is developing, and this may well foreshadow the beginning of the second era of product development. This Biosimilars 2.0 period will likely be characterized by the development of complex products, global harmonization of standards, and the increasing demand for long-term monitoring of pharmaceuticals. The products developed in this period should exhibit high levels of fidelity to the reference products and should be rigorously evaluated in analytical, non-clinical and clinical comparisons. Additionally, Biosimilars 2.0 manufacturers should strive for transparency in their labels and take proactive strides to be accountable to providers and patients for the quality of their products. An important opportunity now exists for the healthcare community, industry and regulators to work in partnership to outline the appropriate standards for these products to facilitate increased access while meeting patients' needs.

IEEE802.15.6 NB portable BAN clinic and M2M international standardization.  

PubMed

The increase of non communicable diseases (NCDs) will change the direction of health services to emphasize the role of preventive medicine in healthcare services. The first short-range medical body are network (BAN) standard IEEE802.15.6 is expected to be used for secure and user-friendly sensor devices for portable medical equipment. A BAN is an enabler for uploading medical data to a backend system for remote diagnoses and treatment. Machine-to-Machine (M2M) infrastructure is also a key technology for providing flexible and affordable services extending electronic health record (EHR) systems. This paper proposes a BAN-based portable clinic that collects health-check data from user-friendly medical devices and sensors and sends the data to a local backend server, and it evaluates the clinic in fields of actual usage. We discuss issues experienced from actual deployment of the system and focus on integrating it into upcoming healthcare M2M infrastructure to achieve affordable and dependable clinic services. We explain the components and workflow of the clinic and the system model. The system is set up at a temporary health center and has a network link to a remote medical help center. The paper concludes with our plan to introduce our system to contribute to internationally standardized preventive medicine. PMID:24110023

Simulation of the radiation fields of the Beta Secondary Standard BSS 2  

NASA Astrophysics Data System (ADS)

Since several years, the irradiation facility for beta radiation, the Beta Secondary Standard BSS 2 developed at PTB, is in worldwide use to irradiate devices with calibrated beta sources. In this work the electron and photon particle spectra of the BSS 2 radiation fields are made available as data files, in addition angular distributions and the depth dose profiles are given. The spectra were determined using the Monte Carlo particle transport code BEAMnrc and are provided as electronic files. In order to verify the simulations, from the same simulations the depth dose curves in a phantom were deduced and compared with corresponding measurements — the agreement is quite good — proving the correctness of the particle spectra.

Screening for musculoskeletal deviations--a challenge for the physical therapist. The Utah Study.  

PubMed

We conducted an on-site examination in selected middle and junior high schools in Utah to determine the incidence of selected musculoskeletal deviations. During a regular school year, we screened 4,670 children. The students we examined represented a random sample of students in the sixth through the ninth grades from a population of 81,047 students. Among the 2,192 boys and 2,478 girls examined, we noted a total of 10,551 postural deviations. Eighteen categories of deviations of the musculoskeletal system were examined visually. Lordosis was the most common postural deviation seen (45%), and torticollis was noted least commonly (0%). Scoliosis was noted in 7% of the total population, with a girl-boy ratio of 2:1. Both the lack of body postural awareness we observed among the children and the significant findings of this study should warrant initiation of more responsible educational programs in the public schools. An apparent need for a uniform statewide screening program was demonstrated. PMID:3615591

Long life 80Ah standard IPV NiH2 battery cell  

NASA Astrophysics Data System (ADS)

A standard Nickel-Hydrogen (NiH2) Individual Pressure Vessel (IPV) battery cell is needed to meet future low cost, high performance mission requirements for NASA, military, and civil space programs. A common or standard cell design has evolved from the heritage of HST, Milstar, and other Air Force Mantech cell designs with substantial flight experience, while incorporating some of the historical COMSAT cell design features described in a previous NASA publication. Key features include slurry process nickel electrodes having high strength, long life and high yield (lower cost), and dual layer zircar separators for improved KOH retention, uniformality, and longer life. The cell design will have a zirconium oxide wall wick inside the pressure vessel to redistribute electrolyte and extend life. The slurry electrode will be 35 mils thick to take advantage of qualified cell mechanical configurations and proven assembly and activation techniques developed by Eagle Picher Industries (EPI) for the Hubble Space Telescope (HST) RNH-90-3 and 'Generic HST' RNH-90-5 cell designs with back-to-back nickel electrodes produced by the dry sinter process. The 80Ah common cell design can be scaled to meet capacity requirements from 60Ah to 100Ah. Producibility, commonality, and long life performance will be enhanced with the robust cell design described herein.

Hook and loop fastener on loose prisms assists in measuring ocular deviation.  

PubMed

It is difficult to hold a pair of loose prisms in one hand. Doing so can lead to inaccuracy, which worsens with large-angle exotropia or vertical deviations. The authors applied a self-adhesive hooked Velcro (Velcro Sticky Back Tape, Velcro USA Inc., Manchester, NH) strip to the base and the top of loose prisms. They applied the complementary looped Velcro to a wooden bar. As a result, a pair of prisms could be suspended horizontally and/or vertically while being held in one hand. Forty consecutive patients undergoing strabismus surgery without adjustable sutures were retrospectively studied to evaluate the accuracy of this method. Clinical use confirmed its ease and convenience. Of 19 patients with exotropia and 15 patients with esotropia (mean ages 41.9 and 15.7 years, respectively; mean deviations 44.7 and 49.8 D, respectively), 4 patients with abducens paralysis, and 2 patients with trochlear palsies, 1 surgery achieved less than 10 D of residual deviation in all but 2 (5.9%). This simple, inexpensive system can assist with the clinical evaluation of ocular deviation. PMID:9760618

How Marginal Deviations Sometimes Grow Into Serious Aggression  

PubMed Central

We offer a theory of marginal deviations that articulates the processes through which initial behavior that is only slightly deviant from the norm gets transformed into more serious antisocial outcomes. We present evidence that, of the one third of the population that is marginally deviant, about one fourth (or 8% of the total population) becomes seriously deviant over time. Hypothesized factors in this transformation involve the child actor, peer observer-judges, and social transactions between them in processes that derive from self-fulfilling prophecies and dynamic systems theory. Hypotheses and studies are proposed to address the circumstances and processes that determine whether a marginal deviation will be bought back to the norm (through assimilation and attenuation) or accelerated to severe deviance (through accommodation and amplification).

Method for improving cuttings transport in deviated wells  

SciTech Connect

An improved method of drilling a deviated well is effected by injecting a slug or series of slugs of a shear thickening fluid down the drill string ahead of the drilling fluid and into the annulus formed about the drill string to displace cuttings that accumulate in the annular regions where the drill string lies near the lower side of the deviated portion of the borehole thereby increasing cuttings transport efficiency. The shear thickening fluid has characteristics that enable it to dislodge and disperse the accumulated cuttings in that it undergoes a reversible, isothermal, increase in viscosity when subjected to an increasing shear rate. Slug volumes vary between 0.05 and 5 percent of the annulus volume between the drill string and the wellbore wall.

Standard enthalpy of formation of La2Te3O9 and La2Te4O11  

NASA Astrophysics Data System (ADS)

Lanthanum tellurites, La2Te3O9 and La2Te4O11, have been prepared by the solid state synthesis route and characterized for their phase and chemical compositions by XRD and ICP-AES analyses. The molar enthalpies of solution of La2Te3O9(s), La2Te4O11(s), La2O3(s) and TeO2(s) in 0.150 dm3 of 10.98 mol dm-3 HCl were measured using an isoperibol calorimeter. From these results and other auxiliary data the standard molar enthalpy of formation of La2Te3O9(s) and La2Te4O11(s) were derived to be (-2814.6 ± 12.9) kJ mol-1 and (-3116.5 ± 17.3) kJ mol-1, respectively, at 298.15 K which are the first reported thermodynamic data on these compounds at 298.15 K.

Geometry of river networks. I. Scaling, fluctuations, and deviations  

SciTech Connect

This paper is the first in a series of three papers investigating the detailed geometry of river networks. Branching networks are a universal structure employed in the distribution and collection of material. Large-scale river networks mark an important class of two-dimensional branching networks, being not only of intrinsic interest but also a pervasive natural phenomenon. In the description of river network structure, scaling laws are uniformly observed. Reported values of scaling exponents vary, suggesting that no unique set of scaling exponents exists. To improve this current understanding of scaling in river networks and to provide a fuller description of branching network structure, here we report a theoretical and empirical study of fluctuations about and deviations from scaling. We examine data for continent-scale river networks such as the Mississippi and the Amazon and draw inspiration from a simple model of directed, random networks. We center our investigations on the scaling of the length of a subbasin's dominant stream with its area, a characterization of basin shape known as Hack's law. We generalize this relationship to a joint probability density, and provide observations and explanations of deviations from scaling. We show that fluctuations about scaling are substantial, and grow with system size. We find strong deviations from scaling at small scales which can be explained by the existence of a linear network structure. At intermediate scales, we find slow drifts in exponent values, indicating that scaling is only approximately obeyed and that universality remains indeterminate. At large scales, we observe a breakdown in scaling due to decreasing sample space and correlations with overall basin shape. The extent of approximate scaling is significantly restricted by these deviations, and will not be improved by increases in network resolution.

We consider the problem of large deviations for a two-time-scale reflected diffusion process, possibly with delays in the dynamical terms. The Dupuis-Ellis weak convergence approach is used. It is perhaps the most intuitive and simplest for the problems of concern. The results have applications to the problem of approximating optimal controls for two-time-scale systems via use of the averaged equation.

Ephesite, Na(LiAl2) [Al2Si2O10] (OH)2: I. thermal stability and standard state thermodynamic properties  

NASA Astrophysics Data System (ADS)

Ephesite, Na(LiAl2) [Al2Si2O10] (OH)2, has been synthesized for the first time by hydrothermal treatment of a gel of requisite composition at 300? T(° C)?700 and P_{H_2 O} upto 35 kbar. At P_{H_2 O} between 7 and 35 kbar and above 500° C, only the 2M1 polytype is obtained. At lower temperatures and pressures, the 1M polytype crystallizes first, which then inverts to the 2M1 polytype with increasing run duration. The X-ray diffraction patterns of the 1M and 2M1 poly types can be indexed unambiguously on the basis of the space groups C2 and Cc, respectively. At its upper thermal stability limit, 2M1 ephesite decomposes according to the reaction (1) 410_2004_Article_BF00380223_TeX2GIFE1.gif begin{gathered} {text{Na(LiAl}}_{text{2}} {text{) [Al}}_{text{2}} {text{Si}}_{text{2}} {text{O}}_{{text{10}}} {text{] (OH)}}_{text{2}} \\ {text{ephesite}} \\ {text{ = Na[AlSiO}}_{text{4}} {text{] + LiAl[SiO}}_{text{4}} {text{] + }}? {text{ - Al}}_{text{2}} {text{O}}_{text{3}} {text{ + H}}_{text{2}} {text{O}} \\ {text{nepheline }}? {text{ - eucryptite corundum}} \\ Five reversal brackets for (1) have been established experimentally in the temperature range 590 750° C, at P_{H_2 O} between 400 and 2500 bars.

The strongest renormalization-group effects are found for the operators with the Dirac structures (1-?5)?(1+?5) and (1-?5)?(1-?5). We calculate the matrix elements < K¯0QiK0> in the NDR scheme using the lattice results in the LRI scheme. We give expressions for the mass differences ?MK and ?MB and the CP-violating parameter ?K in terms of the non-perturbative parameters Bi and the Wilson coefficients Ci(?t). The latter summarize the dependence on new physics contributions.

Evaluation of Bi as internal standard to minimize matrix effects on the direct determination of Pb in vinegar by graphite furnace atomic absorption spectrometry using Ru permanent modifier with co-injection of Pd/Mg(NO3)2  

NASA Astrophysics Data System (ADS)

Bismuth was evaluated as an internal standard for the direct determination of Pb in vinegar by graphite furnace atomic absorption spectrometry using Ru as a permanent modifier with co-injection of Pd/Mg(NO3)2. The correlation coefficient of the graph plotted from the normalized absorbance signals of Bi versus Pb was r = 0.989. Matrix effects were evaluated by analyzing the slope ratios between the analytical curve obtained from reference solutions prepared in 0.2% (v/v) HNO3 and analytical curves obtained from Pb additions in red and white wine vinegar samples. The calculated ratios were around 1.04 and 1.02 for analytical curves established applying an internal standard and 1.3 and 1.5 for analytical curves without. Analytical curves in the 2.5 15 ?g L- 1 Pb concentration interval were established using the ratio Pb absorbance to Bi absorbance versus analyte concentration, and typical linear correlations of r = 0.999 were obtained. The proposed method was applied for direct determination of Pb in 18 commercial vinegar samples and the Pb concentration varied from 2.6 to 31 ?g L- 1. Results were in agreement at a 95% confidence level (paired t-test) with those obtained for digested samples. Recoveries of Pb added to vinegars varied from 96 to 108% with and from 72 to 86% without an internal standard. Two water standard reference materials diluted in vinegar sample were also analyzed and results were in agreement with certified values at a 95% confidence level. The characteristic mass was 40 pg Pb and the useful lifetime of the tube was around 1600 firings. The limit of detection was 0.3 ?g L- 1 and the relative standard deviation was ? 3.8% and ? 8.3% (n = 12) for a sample containing 10 ?g L- 1 Pb with and without internal standard, respectively.

? signals at LEP2 energies in the minimal supersymmetric standard model  

NASA Astrophysics Data System (ADS)

In this paper we compare 0954-3899/23/5/007/img7 and 0954-3899/23/5/007/img8 into four-fermion production at centre-of-mass energies typical of LEP2 and somewhat larger. The theoretical framework considered is the minimal supersymmetric standard model. The interest in exploiting the 0954-3899/23/5/007/img9 CERN collider at values of 0954-3899/23/5/007/img10 greater than 192 GeV could come from the discovery of supersymmetric signals during runs at lower energy. If these indicate that a charged Higgs boson exists in the mass range 0954-3899/23/5/007/img11, then a few years of running at 0954-3899/23/5/007/img12 and nominal luminosity could make the detection of such scalars feasible, in the purely leptonic channel 0954-3899/23/5/007/img13 and, for small 0954-3899/23/5/007/img14, also in the semi-hadronic(leptonic) channel 0954-3899/23/5/007/img15. Charged Higgs bosons of the above nature cannot be produced by the beam energies approved at present for LEP2. However, if runs beyond the so-called `192 GeV cryogenic limit' will be approved by the CERN Council, our selection procedure will enable us to establish the presence, or otherwise, of charged Higgs bosons in the mentioned mass range.

Genomic predictors of the maximal O2 uptake response to standardized exercise training programs  

PubMed Central

Low cardiorespiratory fitness is a powerful predictor of morbidity and cardiovascular mortality. In 473 sedentary adults, all whites, from 99 families of the Health, Risk Factors, Exercise Training, and Genetics (HERITAGE) Family Study, the heritability of gains in maximal O2 uptake (V?o2max) after exposure to a standardized 20-wk exercise program was estimated at 47%. A genome-wide association study based on 324,611 single-nucleotide polymorphisms (SNPs) was undertaken to identify SNPs associated with improvements in V?o2max Based on single-SNP analysis, 39 SNPs were associated with the gains with P < 1.5 × 10?4. Stepwise multiple regression analysis of the 39 SNPs identified a panel of 21 SNPs that accounted for 49% of the variance in V?o2max trainability. Subjects who carried ?9 favorable alleles at these 21 SNPs improved their V?o2max by 221 ml/min, whereas those who carried ?19 of these alleles gained, on average, 604 ml/min. The strongest association was with rs6552828, located in the acyl-CoA synthase long-chain member 1 (ACSL1) gene, which accounted by itself for ?6% of the training response of V?o2max. The genes nearest to the SNPs that were the strongest predictors were PR domain-containing 1 with ZNF domain (PRDM1); glutamate receptor, ionotropic, N-methyl-d-aspartate 3A (GRIN3A); K+ channel, voltage gated, subfamily H, member 8 (KCNH8); and zinc finger protein of the cerebellum 4 (ZIC4). The association with the SNP nearest to ZIC4 was replicated in 40- to 65-yr-old, sedentary, overweight, and dyslipidemic subjects trained in Studies of a Targeted Risk Reduction Intervention Through Defined Exercise (STRRIDE; n = 183). Two SNPs were replicated in sedentary obese white women exercise trained in the Dose Response to Exercise (DREW) study (n = 112): rs1956197 near dishevelled associated activator of morphogenesis 1 (DAAM1) and rs17117533 in the vicinity of necdin (NDN). The association of SNPs rs884736 in the calmodulin-binding transcription activator 1 (CAMTA1) locus and rs17581162 ?68 kb upstream from regulator of G protein signaling 18 (RGS18) with the gains in V?o2max in HERITAGE whites were replicated in HERITAGE blacks (n = 247). These genomic predictors of the response of V?o2max to regular exercise provide new targets for the study of the biology of fitness and its adaptation to regular exercise. Large-scale replication studies are warranted.

Baseline mean deviation and rates of visual field change in treated glaucoma patients  

PubMed Central

Purpose To evaluate the relationships between baseline visual field (VF) mean deviation (MD) and subsequent progression in treated glaucoma. Methods Records of patients seen in a glaucoma practice between 1999 and 2009 were reviewed. Patients with glaucomatous optic neuropathy, baseline VF damage, and ?8 SITA-standard 24-2 VF were included. Patients were divided into tertiles based upon baseline MD. Automated pointwise linear regression determined global and localized rates (decibels (dB) per year) of change. Progression was defined when two or more adjacent test locations in the same hemifield showed a sensitivity decline at a rate of >1.0 ?dB per year, P<0.01. Results For mild, moderate, and severe groups, progression was noted in 29.5, 31.2, and 26.0% of eyes (P=0.50) and global rates of VF change of progressing eyes were ?1.3±1.2, ?1.01±0.7, and ?0.9±0.5?dB/year (P=0.09, analysis of variance). Within these groups, intraocular pressure (IOP) in stable vs progressing eyes were 15.5±3.3 vs 17.0±3.1 (P<0.01), 15.4±3.3 vs 15.9±2.5 (P=0.28), and 14.0±2.8 vs 14.8±2.3?mm?Hg (P=0.07). More glaucoma filtering surgeries were performed in eyes with worse MD. There was no significant difference between groups regarding their risk of progression in both univariate (P=0.50) and multivariate (P=0.26) analyses adjusting for differences in follow-up IOP. Conclusions After correcting for differences in IOP in treated glaucoma patients, we did not find a relationship between the rate of VF change (dB per year) and the severity of the baseline VF MD. This finding may have been due to more aggressive IOP lowering in eyes with more severe disease. Eyes with lower IOP progressed less frequently across the spectrum of VF loss.

Nuclear deviation in hepatic parenchymal cells on sinusoidal surfaces in Arctic animals.  

PubMed

In normal rat and human, most of the nuclei of hepatic parenchymal cells are centrally located in the cytoplasm. However, it is reported that the nuclei of hepatic parenchymal cells are situated at a deviated position on sinusoidal surfaces under pathological situations such as chronic hepatitis, hepatocellular carcinoma, adenomatous hyperplasia, or regeneration. During a study on the mechanism of extreme vitamin A-accumulation in hepatic stellate cells of arctic animals including polar bears, arctic foxes, bearded seals, and glaucous gulls, we noticed that these arctic animals displayed the nuclear deviation in hepatic parenchymal cells on sinusoidal surfaces. In this study, we assessed the frequency of hepatic parenchymal cells showing the nuclear deviation on the sinusoidal surfaces in arctic animals. A significantly higher frequency of the nuclear deviation in hepatic parenchymal cells was seen in polar bears (89.8+/-3.4%), arctic foxes (68.6+/-10.5%), bearded seals (63.6+/-8.4%), and glaucous gulls (24.2+/-5.8%), as compared to that of control rat liver (9.8+/-3.5%). However, no pathological abnormality such as fibrosis or necrosis was observed in hepatic parenchymal and nonparenchymal cells of arctic animals, and there were no differences in the intralobular distribution of parenchymal cells displaying the nuclear deviation in the livers from either arctic animals and control rats. The hepatic sinusoidal littoral cells such as stellate cells or extracellular matrix components in the perisinusoidal spaces may influence the nuclear positioning and hence the polarity and intrinsic physiological function of parenchymal cells.

Geodesic Deviation Equation, Gödel Metric and Inverse Scattering  

NASA Astrophysics Data System (ADS)

Equations for geodesic deviation (GDE) are deduced for the space-time metric of Gödel type. The equation turns out to be a matrix Schrödinger problem. It is then demonstrated that one can generate nonlinear equations for the coefficient functions of the metric if a “time” evolution equation is adjoined to the GDE. Soliton like solutions for the metric functions can be obtained through an inverse scattering transform of the matrix Schrödinger problem. Thereby a solution of the GDE equation is also determined by the wave function of the IST.

Trial Construction of Continuously Variable Deviation Angle Mechanism  

SciTech Connect

A prototype continuously variable deviation angle mechanism for a beam-line monochromator is constructed and demonstrated to have a repeatability of measurement of better than {+-}0.15 sec in one direction. The differences in positioning from opposite directions are 1.4 sec for the grating and 0.15 sec for the tilting plane mirror. Positioning should therefore be conducted from one direction for exact positioning, although the rotation angles measured by the rotary encoder are coupled directly with the rotation axis of the optical components.

Measuring instrument for radial composite deviations of high-precision master gear  

NASA Astrophysics Data System (ADS)

During double flank rolling composite detection, the radial composite deviations of master gears has been existed and transferred to the measured gear by the primary harmonic curve. In order to improve measurement accuracy, a measuring instrument is developed for radial composite deviations of high-precision master gear in the paper. This instrument uses the structure of spring-suspend swing span to overcome the shortcomings of large rotation errors, low sensitivity, low resolution and large measuring force appearing in the traditional combination-type gear inspection instrument. Artificial intelligence technology is used to improve the efficiency and accuracy of this instrument. The result is that the measuring apparatus is able to meet the requirement and improve efficiency through the measuring experiments on master gears of precision grade 2 with modulus 2 mm and 3 mm, respectively.

Determinants of intention to deviate from clinical practice guidelines.  

PubMed

The volitional nature of procedural violations in work systems creates a challenge for human factors research and practice. In order to understand how violations are caused and what can be done to mitigate them, there is a need to determine the influence of workers' beliefs about rules and guidelines. This study demonstrates the use of a social psychological approach to investigate the beliefs of anaesthetists about clinical practice guidelines. A survey was completed by 629 consultant anaesthetists, who rated their beliefs about deviation from three guidelines (performing pre-operative visits; checking anaesthetic equipment; handling intravenous fluid bags). Regression analysis indicated that the belief ratings predicted self-rated intention to deviate from the guidelines. Implications for understanding anaesthetists' adherence to guidelines are discussed. STATEMENT OF RELEVANCE: This study builds upon previous work by the authors, presenting a more detailed insight into potential causes of procedural violations in healthcare. The study also demonstrates the use of a social psychological method to the investigation of violations. Hence, it is of interest to researchers and practitioners interested in human reliability, especially in healthcare. PMID:20191414

DEVIATIONS IN INFLUENZA SEASONALITY: ODD COINCIDENCE OR OBSCURE CONSEQUENCE?  

PubMed Central

In temperate regions, influenza typically arrives with the onset of colder weather. Seasonal waves travel over large spaces covering many climatic zones in a relatively short period of time. The precise mechanism for this striking seasonal pattern is still not well understood and the interplay of factors that influence the spread of infection and the emergence of new strains is largely unknown. The study of influenza seasonality has been fraught with problems. One of these is the ever shifting description of illness due to influenza and the use of both the historical definitions and new definitions based on actual isolation of the virus. The compilation of records describing influenza oscillations on a local and global scale is massive, but the value of these data is a function of the definitions used. In this review we argue that both observations of seasonality and deviation from the expected pattern stem from the nature of this disease. Heterogeneity in seasonal patterns may arrive from differences in behavior of specific strains, emergence of a novel strain or cross-protection from previously observed strains. Most likely the seasonal patterns emerge from interactions of individual factors behaving as coupled resonators. We emphasize that both seasonality and deviations from it may merely be a reflection of our inability to disentangle signal from noise, be it due to ambiguity in measurement and/or terminology. We conclude the review with suggestions for new promising and realistic directions with tangible consequences to model complex influenza dynamics in order to effectively control infection.

How to optimize motor drilling in non-deviated wells  

SciTech Connect

Since the introduction of drilling with positive displacement motors (PDM) in the 1960s, considerable effort has been devoted to increasing motor life, reliability, power and efficiency. Nabors Drilling has studied vertical drilling with downhole motors extensively, and has found that a detailed hydraulics analysis combined with optimized motor-bit selection can improve the economics markedly. Many tangible and intangible benefits have been documented. To reduce bottomhole assembly (BHA) failures and improve deviation control, Nabors Drilling implemented PDMs in the 9 7/8-in. upper hole section during a recent 1-year drilling program. This interval consisted of a sandstone formation to be drilled with a tooth type bit and a shale to be drilled with a polycrystalline diamond compact (PDC) bit. BHA failures were eliminated and in turn, fishing time and costs were reduced. Deviation control was also improved.The penetration rate increased significantly, reducing operating time from 12 days to 8 days. In addition, PDMs eliminated a trip when stabilizers were used while drilling out of the casing shoe, and extended PDC bit life.

Large-deviation achromatic Risley prisms pointing systems  

NASA Astrophysics Data System (ADS)

As part of the Infrared Eye project, this article describes the design of large-deviation, achromatic Risley prisms scanning systems operating in the 0.5 - 0.92 and 8 - 9.5 microns spectral regions. Designing these systems is challenging due to the large deviation required (zero - 25 degrees), the large spectral bandwidth and the mechanical constraints imposed by the need to rotate the prisms to any position in 1/30 second. A design approach making extensive use of the versatility of optical design softwares is described. Designs consisting of different pairs of optical materials are shown in order to illustrate the trade-off between chromatic aberration, mass and vignetting. Control of chromatic aberration and reasonable prism shape is obtained over 8 - 9.5 microns with zinc sulfide and germanium. The design is more difficult for the 0.5 - 0.92 microns band. Trade-offs consist in using sapphire with Cleartran over a reduced bandwidth (0.75 - 0.9 microns) or acrylic singlets with the Infrared Eye in active mode (0.85 - 0.86 microns). Non-sequential ray-tracing is used to study the effects of fresnelizing one element of the achromat to reduce its mass, and to evaluate detector narcissus in the 8 - 9.5 microns region.

DEVIATIONS FROM THE SCHMIDT-KENNICUTT RELATIONS DURING EARLY GALAXY EVOLUTION  

SciTech Connect

We utilize detailed time-varying models of the coupled evolution of stars and the H I, H{sub 2}, and CO-bright H{sub 2} gas phases in galaxy-sized numerical simulations to explore the evolution of gas-rich and/or metal-poor systems, which are expected to be numerous in the early universe. The inclusion of the CO-bright H{sub 2} gas phase and the realistic rendering of star formation as an H{sub 2}-regulated process (and the new feedback processes that this entails) allow the most realistic tracking of strongly evolving galaxies and much better comparison with observations. We find that while galaxies eventually settle into states conforming to the Schmidt-Kennicutt (S-K) relations, significant and systematic deviations of their star formation rates (SFRs) from the latter occur, and are especially pronounced and prolonged for metal-poor systems. The largest such deviations occur for gas-rich galaxies during not only the early evolutionary stages but also during brief periods at later stages. Given that gas-rich and/or metal-poor states of present-epoch galaxies are expected in the early universe while a much larger number of mergers frequently reset non-isolated systems to gas-rich states, even brief periods of sustained deviations of their SFRs from those expected from the S-K relations may come to characterize significant periods of their stellar mass built-up. This indicates potentially serious limitations of S-K-type relations as reliable sub-grid elements of star formation physics in simulations of structure formation in the early universe. We anticipate that galaxies with marked deviations from the S-K relations will be found at high redshifts as unbiased inventories of total gas mass become possible with ALMA and the EVLA.

Current activities of ISO TC229/WG2 on purity evaluation and quality assurance standards for carbon nanotubes.  

PubMed

The current standardization activities of ISO (International Organization for Standardization) TC229 on "Nanotechnology" are introduced with focus on the work of WG2 (Working Group 2) for "measurement and characterization". Seven project groups of WG2 are actively preparing standard protocols (technical specifications) for characterization of single-wall carbon nanotubes (SWCNTs) by measurement methods such as TEM (transmission electron microscopy), SEM (scanning electron microscopy), EDX (energy-dispersive X-ray analysis), UV-Vis-NIR (ultraviolet-visible-near infrared) absorption spectroscopy, NIR-photoluminescence spectroscopy, EGA (evolved gas analysis)-GC-MS (gas chromatography-mass spectrometry), TGA (thermogravimetric analysis), and Raman spectroscopy; this work is described. The features of purity evaluation of SWCNTs by these methods are also briefly described and compared. Also described are two project groups of WG2 that are preparing standard protocols for characterization of multiwall CNTs (MWCNTs), aiming at the purity control by measurement of moisture content, ash content, metallic constituents, volatile content, polyaromatic hydrocarbon content, and carbon materials excluding MWCNTs. Other important properties for characterization of MWCNT, for example disorder, burning property, stacking nature, length, morphology, and inner/outer diameter, etc., are also mentioned. Finally, the importance and urgency of standardization for potential risk assessment of CNTs is briefly described, and current joint activity of ISO TC229 WG2 and WG3 for physicochemical characterization of engineered nanoscale materials for toxicological assessment is introduced.

Development of a Rapid, Standardized Data Inventory for R2K Field Programs  

NASA Astrophysics Data System (ADS)

Effective data management for Ridge2000 requires the production of a complete data inventory for every field program in a timely and standardized way. We are developing a set of forms to document 1.) basic field program information (dates and locations, platform, science party, etc); 2.) an inventory of sensor systems, data types (marine geophysical, physical and chemical oceanographic, rock and sediment samples, and biological), and file formats; 3.) supplemental attachments (written reports, instrument diagrams, etc); and 4.) a basic navigation track. We regard this as the minimal set of metadata which should be produced immediately at the end of a field program, in order to publicize it in an online database and satisfy agency requirements. We have developed a prototype set of Portable Document Format (PDF) forms which can be completed during a cruise through a combination of manual and automated input. PDF is a stable and widely-used format, with software available as both a commercial product (Adobe Acrobat) and an open-source library (http://www.pdflib.org). Completing a PDF form requires only the Acrobat Reader software, which is freely available for every major computing platform. Acrobat offers extensive functionality to aid in data inventory, including the ability to verify content on-the-fly, import data from other files and forms, show controlled vocabularies as pop-up menus, export to XML format, and print a high-quality readable report. Prototype forms have been tested on a recent transit of the CGC Healy, and we plan to continue testing on other ships and soliciting community feedback over the next several months. We envision a long-term plan in which a master set of forms is deployed with every R2K field program, along with a copy of Acrobat Reader, on lightweight storage media such as USB keys. The completed forms will then be transmitted to the data management center, where they are ingested automatically and the information made available in the online R2K database.

In this letter, we investigate the contributions which W boson helicity fractions in top quark decay receive from a two-Higgs doublet model, a top-color assisted technicolor (TC2) and the noncommutative extension of the Standard Model. It is shown that the deviations coming from these models are much less than the experimental sensitivity in measurement of the helicity fractions.

Single-Point Mutations and Protein Structure Deviations  

NASA Astrophysics Data System (ADS)

The V4 proteins, LmcA and LmcB, in the social amoeba Dictyostelium are believed to play an important role in the growth to development transition of the organism. Whether or not a normal transition occurs depends on whether one or the other or both of the proteins is expressed. The proteins only differ by one non-conserved residue. In order to understand the possible differences in protein structure and function we performed an ab initio structure calculation for each protein using the Monte Carlo fragment insertion method implemented by Rosetta. The predicted structures were found to be dramatically different. This result inspired a comprehensive survey of all the Protein Data Bank structures related by a single-point mutation. The distribution of mutations with respect to the resulting rms deviation in atomic coordinates was found to have a simple exponential behavior.

The Effects of Marginal Deviations on Behavioral Development  

PubMed Central

This investigation was conceptually framed within the theory of marginal deviations (Caprara & Zimbardo, 1996) and sought evidence for the general hypothesis that some children who initially show marginal behavioral problems may, over time, develop more serious problems depending partly on other personal and behavioral characteristics. To this end, the findings of two studies conducted, respectively, with American elementary school children and Italian middle school students are reviewed. These two studies show that hyperactivity, cognitive difficulties, low special preference, and lack of prosocial behavior increase a child’s risk for growth in aggressive behavior over several school years. More importantly, they also show that equivalent levels of these risk factors have a greater impact on the development of children who, early on, were marginally aggressive.

Deviations from scale invariance near a general conformal background  

NASA Astrophysics Data System (ADS)

Deviations from scale invariance resulting from small perturbations of a general two-dimensional conformal field theory are studied. They are expressed in terms of ?-functions for the renormalization of general couplings under a local change of scale. The ?-functions for a homogeneous background are given perturbatively in terms of the data of the original conformal theory without any specific assumptions on its nature. The renormalization of couplings to primary operators and to first descendents is considered as well as that of a dilatonic type which involve explicit dependence on world sheet curvature. The first descendent couplings are interpreted as gauge degrees of freedom in the string field action and the corresponding gauge transformation is spelled out.

Probing deviations from tribimaximal mixing through ultrahigh energy neutrino signals  

SciTech Connect

We investigate deviation from the tribimaximal mixing in the case of ultrahigh energy neutrino using the ICECUBE detector. We consider the ratio of the number of muon tracks to the shower generated due to eletrons and hadrons. Our analysis shows that for tribimaximal mixing the ratio comes out around 4.05. Keeping {theta}{sub 12} and {theta}{sub 23} fixed at tribimaximal value, we have varied the angle {theta}{sub 13}=3 deg. , 6 deg. , 9 deg. and the value of the ratio gradually decreases. The variation of ratio lies within 8% to 18% from the tribimaximal mixing value and it is very difficult to detect such a small variation by the ICECUBE detector.

The author addressed the question of consistency in psychotherapists' countertransference feelings. Research findings have indicated that the therapist's own personal feeling style may be more important than the patient's impact on the therapist's feelings. In this study, the feelings of 9 psychotherapists toward 28 patients were followed by using checklist self-report after each session during moderately long psychotherapies. ANOVAs and discriminant analyses showed that the therapists were very consistent in their feeling style over different patients and over time. The consistency in feelings toward the individual patients was smaller. Deviations from consistency are analyzed, and their importance for the understanding of different aspects of the countertransference is discussed. It is suggested that a meaningful use of the countertransference concept ought to be based on systematic identifications of recurrent and deviant patterns in the therapist's reactions.

(Terminology standardization)  

SciTech Connect

Terminological requirements in information management was but one of the principal themes of the 2nd Congress on Terminology and Knowledge Engineering. The traveler represented the American Society for Testing and Materials' Committee on Terminology, of which he is the Chair. The traveler's invited workshop emphasized terminology standardization requirements in databases of material properties as well as practical terminology standardizing methods. The congress included six workshops in addition to approximately 82 lectures and papers from terminologists, artificial intelligence practitioners, and subject specialists from 18 countries. There were approximately 292 registrants from 33 countries who participated in the congress. The congress topics were broad. Examples were the increasing use of International Standards Organization (ISO) Standards in legislated systems such as the USSR Automated Data Bank of Standardized Terminology, the enhanced Physics Training Program based on terminology standardization in Physics in the Chinese province of Inner Mongolia, and the technical concept dictionary being developed at the Japan Electronic Dictionary Research Institute, which is considered to be the key to advanced artificial intelligence applications. The more usual roles of terminology work in the areas of machine translation. indexing protocols, knowledge theory, and data transfer in several subject specialties were also addressed, along with numerous special language terminology areas.

Validation for 2D/3D registration II: The comparison of intensity- and gradient-based merit functions using a new gold standard data set  

PubMed Central

Purpose: A new gold standard data set for validation of 2D/3D registration based on a porcine cadaver head with attached fiducial markers was presented in the first part of this article. The advantage of this new phantom is the large amount of soft tissue, which simulates realistic conditions for registration. This article tests the performance of intensity- and gradient-based algorithms for 2D/3D registration using the new phantom data set. Methods: Intensity-based methods with four merit functions, namely, cross correlation, rank correlation, correlation ratio, and mutual information (MI), and two gradient-based algorithms, the backprojection gradient-based (BGB) registration method and the reconstruction gradient-based (RGB) registration method, were compared. Four volumes consisting of CBCT with two fields of view, 64 slice multidetector CT, and magnetic resonance-T1 weighted images were registered to a pair of kV x-ray images and a pair of MV images. A standardized evaluation methodology was employed. Targets were evenly spread over the volumes and 250 starting positions of the 3D volumes with initial displacements of up to 25 mm from the gold standard position were calculated. After the registration, the displacement from the gold standard was retrieved and the root mean square (RMS), mean, and standard deviation mean target registration errors (mTREs) over 250 registrations were derived. Additionally, the following merit properties were computed: Accuracy, capture range, number of minima, risk of nonconvergence, and distinctiveness of optimum for better comparison of the robustness of each merit. Results: Among the merit functions used for the intensity-based method, MI reached the best accuracy with an RMS mTRE down to 1.30 mm. Furthermore, it was the only merit function that could accurately register the CT to the kV x rays with the presence of tissue deformation. As for the gradient-based methods, BGB and RGB methods achieved subvoxel accuracy (RMS mTRE down to 0.56 and 0.70 mm, respectively). Overall, gradient-based similarity measures were found to be substantially more accurate than intensity-based methods and could cope with soft tissue deformation and enabled also accurate registrations of the MR-T1 volume to the kV x-ray image. Conclusions: In this article, the authors demonstrate the usefulness of a new phantom image data set for the evaluation of 2D/3D registration methods, which featured soft tissue deformation. The author’s evaluation shows that gradient-based methods are more accurate than intensity-based methods, especially when soft tissue deformation is present. However, the current nonoptimized implementations make them prohibitively slow for practical applications. On the other hand, the speed of the intensity-based method renders these more suitable for clinical use, while the accuracy is still competitive.

Study of the 2H(alpha ,gamma)6Li nuclear reaction producing 6Li in standard Big Bang nucleosynthesis  

NASA Astrophysics Data System (ADS)

The 2H(alpha ,gamma )6Li reaction dominates the production of lithium-6 in standard Big Bang nucleosynthesis. Due to its exceedingly low cross section, this reaction has never been studied experimentally at the relevant energies, and consequently the adopted reaction rate depends on uncertain extrapolations. A direct study of the 2H(alpha ,gamma )6Li cross section is currently underway at the LUNA 400 kV accelerator, located deep underground in the Gran Sasso laboratory, Italy. The expected data lie directly at big-bang energies. It is hoped that they help constrain non-standard lithium-6 production scenarios, by putting the standard Big Bang production on a solid experimental footing.

Left-Deviating Prism Adaptation in Left Neglect Patient: Reflexions on a Negative Result  

PubMed Central

Adaptation to right-deviating prisms is a promising intervention for the rehabilitation of patients with left spatial neglect. In order to test the lateral specificity of prism adaptation on left neglect, the present study evaluated the effect of left-deviating prism on straight-ahead pointing movements and on several classical neuropsychological tests in a group of five right brain-damaged patients with left spatial neglect. A group of healthy subjects was also included for comparison purposes. After a single session of exposing simple manual pointing to left-deviating prisms, contrary to healthy controls, none of the patients showed a reliable change of the straight-ahead pointing movement in the dark. No significant modification of attentional paper-and-pencil tasks was either observed immediately or 2 hours after prism adaptation. These results suggest that the therapeutic effect of prism adaptation on left spatial neglect relies on a specific lateralized mechanism. Evidence for a directional effect for prism adaptation both in terms of the side of the visuomanual adaptation and therefore possibly in terms of the side of brain affected by the stimulation is discussed.

Markers typed in genome-wide analysis identify regions showing deviation from Hardy-Weinberg equilibrium  

PubMed Central

Background Deviations from Hardy-Weinberg equilibrium (HWE) are commonly thought of as indicating genotyping errors, population stratification or some other artefact. However they could also arise through important biological mechanisms. In particular, genetic variants having a recessive effect on the successful fertilisation and/or development of an embryo might be manifest through such deviations in an unselected sample of "control" subjects. Findings We investigated genotypes from 463842 autosomal markers from 1504 British subjects. We identified regions in which several neighbouring markers exhibited deviation from HWE in the same direction by considering "heterozygosity scores" in windows of 10 markers. The heterozygosity score for each marker was defined as -log(p) or log(p) according to whether the marker demonstrated increased heterozygosity or homozygosity. In each window the marker with the highest absolute score was ignored and the positive and negative scores were summed for the other nine markers. Windows were selected on the basis of this sum exceeding a given threshold, for which we used values of 50 or 15. For the threshold of 50, we identified 7 regions with increased heterozygosity and for the threshold of 15 we identified 22 regions with increased heterozygosity, 23 with increased homozygosity and 2 containing both kinds of window. The most impressive of these results came from a group of 6 markers at 17q21, each of which showed increased heterozygosity significant at p < 10-190. Conclusion The human genome contains regions which deviate markedly from HWE and these might harbour genes influencing embryonic survival.

Deviation from homeoviscous adaptation in Escherichia coli membranes.  

PubMed Central

The process by which an organism changes the composition of its membranal fatty acids in response to growth temperature, so as to maintain optimal membrane functioning, is known as homeoviscous adaptation (HA). One expression of HA is the constancy of the fluorescence polarization (P) of the lipophilic probe 1,6-diphenyl-1,3,5-hexatriene (DPH) in membranes of cells grown at various temperatures. The P of DPH in the membranes of Escherichia coli was shown by us to be inversely proportional to bacterial growth rate on different carbon sources. This result, implying failure of HA, is now complemented by measurements of DPH lifetimes, which indicate that the dominant variables contributing to the drop in P are (a) the order parameter of the membrane, which goes down, and (b) the fluidity, which may slightly increase. These are then the changes induced by enhanced growth rate. Two additional effects, cell membrane permeability and sensitivity to thermal shock, determined by the diffusion of o-nitrophenylgalactoside (ONPG) and by exposure to 52 degrees C, respectively, are reported to increase with growth rate. We can now conclude that there is a deviation from the principle of HA in E. coli grown at various rates, brought about by controlling the growth media at constant temperatures.

Large deviations of ergodic counting processes: a statistical mechanics approach.  

PubMed

The large-deviation method allows to characterize an ergodic counting process in terms of a thermodynamic frame where a free energy function determines the asymptotic nonstationary statistical properties of its fluctuations. Here we study this formalism through a statistical mechanics approach, that is, with an auxiliary counting process that maximizes an entropy function associated with the thermodynamic potential. We show that the realizations of this auxiliary process can be obtained after applying a conditional measurement scheme to the original ones, providing is this way an alternative measurement interpretation of the thermodynamic approach. General results are obtained for renewal counting processes, that is, those where the time intervals between consecutive events are independent and defined by a unique waiting time distribution. The underlying statistical mechanics is controlled by the same waiting time distribution, rescaled by an exponential decay measured by the free energy function. A scale invariance, shift closure, and intermittence phenomena are obtained and interpreted in this context. Similar conclusions apply for nonrenewal processes when the memory between successive events is induced by a stochastic waiting time distribution. PMID:21867147

Gait deviations induced by visual stimulation in roll.  

PubMed

Locomotion control uses proprioceptive, visual, and vestibular signals. The vestibular contribution has been analyzed previously with galvanic vestibular stimulation (GVS), which constitutes mainly a virtual head-fixed rotation in the roll plane that causes polarity-specific deviations of gait. In this study we examined whether a visual disturbance has similar effects on gait when it acts in the same direction as GVS, i.e., when roll vection is induced by head-fixed visual roll motion stimulation. Random dot patterns were constantly rotated in roll at +/-15 degrees /s on a computer-driven binocular head-mounted display that was worn by eight healthy participants. Their gait trajectories were tracked while they walked a distance of 6 m. A stimulation effect was observed only for the first three to four steps, but not for the whole walking distance. These results are similar to the results of previous GVS studies, suggesting that in terms of the direction of action visual motion stimulations in the roll plane are similar to GVS. Both kinds of stimulation cause only initial balance responses in the roll plane but do not contribute to the steering of gait in the yaw plane. PMID:17909767

Comparison is made between the preparation of trans-1,2-cyclohexanediol in standard glassware (conventional batch production) and in a microreactor (continuous flow production). The reaction sequence involved two exothermic steps where the standard procedure demands slow reagent addition and careful temperature control. In the microreactor, the reaction could be carried out safely with up to 3 times higher reagent concentration. Synthetic benefits were a faster reaction rate and a higher purity product free of colored impurities (a feature of the batch procedure). PMID:18001100

Final Report, Volume 2, The Development of Qualification Standards for Cast Duplex Stainless Steel  

SciTech Connect

The scope of testing cast Duplex Stainless Steel (DSS) required testing to several ASTM specifications, while formulating and conducting industry round robin tests to verify and study the reproducibility of the results. ASTM E562 (Standard Test Method for Determining Volume Fraction by Systematic manual Point Count) and ASTM A923 (Standard Test Methods for Detecting Detrimental Intermetallic Phase in Wrought Duplex Austenitic/Ferritic Stainless Steels) were the specifications utilized in conducting this work. An ASTM E562 industry round robin, ASTM A923 applicability study, ASTM A923 industry round robin, and an ASTM A923 study of the effectiveness of existing foundry solution annealing procedures for producing cast DSS without intermetallic phases were implemented. In the ASTM E562 study, 5 samples were extracted from various cast austenitic and DSS in order to have varying amounts of ferrite. Each sample was metallographically prepared by UT and sent to each of 8 participants for volume fraction of ferrite measurements. Volume fraction of ferrite was measured using manual point count per ASTM E562. FN was measured from the Feritescope�������® and converted to volume fraction of ferrite. Results indicate that ASTM E562 is applicable to DSS and the results have excellent lab-to-lab reproducibility. Also, volume fraction of ferrite conversions from the FN measured by the Feritescope�������® were similar to volume fraction of ferrite measured per ASTM E562. In the ASTM A923 applicability to cast DSS study, 8 different heat treatments were performed on 3 lots of ASTM A890-4A (CD3MN) castings and 1 lot of 2205 wrought DSS. The heat treatments were selected to produce a wide range of cooling rates and hold times in order to study the suitability of ASTM A923 to the response of varying amounts on intermetallic phases [117]. The test parameters were identical to those used to develop ASTM A923 for wrought DSS. Charpy V-notch impact samples were extracted from the castings and wrought DSS and tested per ASTM A923 method B (Charpy impact test). Method A (sodium hydroxide etch test) was performed on one half of a fractured Charpy V-notch impact sample and Method C (ferric chloride corrosion weight loss test) was performed on another half. Test results for the three cast lots and one wrought lot indicate that ASTM A923 is relevant for detecting intermetallic phases in cast DSS. In the ASTM A923 round robin study, five laboratories conducted ASTM A923 Methods A & C on cast DSS material and the lab-to-lab reproducibility of the data was determined. Two groups of samples were sent to the participants. Group 1 samples were tested per ASTM A923 Method A, group 2 samples were tested by ASTM A923 Method C. Testing procedures for this round robin study were identical to those used in the ASTM A923 applicability study. Results from this round robin indicate that there is excellent lab-to-lab reproducibility of ASTM A923 with respect to cast DSS and that ASTM A923 could be expanded to cover both wrought and cast DSS. In the ASTM A923 study of the effectiveness of existing foundry solution annealing procedures for producing cast DSS without intermetallic phases, Ten heats of ASTM A890-4A (CD3MN) in the foundry solution annealed condition were tested per ASTM A923 Methods A, B, & C. Testing of these materials per ASTM A923 was used to determine if the foundry solution anneal procedures were adequate to completely eliminate any intermetallic phases, which may have precipitated during the casting and subsequent heat treatment processes. All heats showed no sign of intermetallic phase per Method A, passed minimum Charpy impact energy requirements per Method B (> 40 ft-lbs @ -40�������°C (-40�������°F)), and showed negligible weight loss per Method C (< 10 mdd). These results indicate that the solution annealing procedure used by foundri

In the ASTM A923 study of the effectiveness of existing foundry solution annealing procedures for producing cast DSS without intermetallic phases, Ten heats of ASTM A890-4A (CD3MN) in the foundry solution annealed condition were tested per ASTM A923 Methods A, B, & C. Testing of these materials per ASTM A923 was used to determine if the foundry solution anneal procedures were adequate to completely eliminate any intermetallic phases, which may have precipitated during the casting and subsequent heat treatment processes. All heats showed no sign of intermetallic phase per Method A, passed minimum Charpy impact energy requirements per Method B (> 40 ft-lbs {at} -40 C (-40 F)), and showed negligible weight loss per Method C (< 10 mdd). These results indicate that the solution annealing procedure used by foundries is adequate to produce a product free from intermetallic phases.

Dispersion measurements with minimum and maximum deviated beams  

Microsoft Academic Search

The prism spectrometer has been the standard apparatus for index of refraction measurements and a typical instrument in undergraduate laboratories for dispersion experiments. Because much care must be employed when aligning a prism spectrometer, a more robust method for measuring index of refraction is needed. By using a laser, prism, rotating platform, and tape measure, we can measure the index

Apricoxib, a Novel Inhibitor of COX-2, Markedly Improves Standard Therapy Response in Molecularly Defined Models of Pancreatic Cancer  

PubMed Central

Purpose COX-2 is expressed highly in pancreatic cancer and implicated in tumor progression. COX-2 inhibition can reduce tumor growth and augment therapy. The precise function of COX-2 in tumors remains poorly understood, but it is implicated in tumor angiogenesis, evasion of apoptosis, and induction of epithelial-to-mesenchymal transition (EMT). Current therapeutic regimens for pancreatic cancer are minimally effective, highlighting the need for novel treatment strategies. Here, we report that apricoxib, a novel COX-2 inhibitor in phase II clinical trials, significantly enhances the efficacy of gemcitabine/ erlotinib in preclinical models of pancreatic cancer. Experimental Design Human pancreatic cell lines were evaluated in vitro and in vivo for response to apricoxib ± standard-of-care therapy (gemcitabine + erlotinib). Tumor tissue underwent posttreatment analysis for cell proliferation, viability, and EMT phenotype. Vascular parameters were also determined. Results COX-2 inhibition reduced the IC50 of gemcitabine ± erlotinib in six pancreatic cancer cell lines tested in vitro. Furthermore, apricoxib increased the antitumor efficacy of standard combination therapy in several orthotopic xenograft models. In vivo apricoxib combination therapy was only effective at reducing tumor growth and metastasis in tumors with elevated COX-2 activity. In each model examined, treatment with apricoxib resulted in vascular normalization without a decrease in microvessel density and promotion of an epithelial phenotype by tumor cells regardless of basal COX-2 expression. Conclusions Apricoxib robustly reverses EMT and augments standard therapy without reducing microvessel density and warrants further clinical evaluation in patients with pancreatic cancer.

Power Transfer Potential to the Southeast in Response to a Renewable Portfolio Standard: Interim Report 2  

SciTech Connect

Electricity consumption in the Southeastern US, not including Florida, is approximately 24% of the total US. The availability of renewable resources for electricity production is relatively small compared to the high consumption. Therefore meeting a national renewable portfolio standard (RPS) is particularly challenging in this region. Neighboring regions, particularly to the west, have significant wind resources and given sufficient long distant transmission these resources could serve energy markets in the SE. This report looks at renewable resource supply relative to demands and the potential for power transfer into the SE. It shows that development of wind resources will depend not only on available transmission capacity but also on electricity supply and demand factors.

Development of a standardized Intranet database of formulation records for nonsterile compounding, Part 2.  

PubMed

In part 1 of this series, we outlined the rationale behind the development of a centralized electronic database used to maintain nonsterile compounding formulation records in the Mission Health System, which is a union of several independent hospitals and satellite and regional pharmacies that form the cornerstone of advanced medical care in several areas of western North Carolina. Hospital providers in many healthcare systems require compounded formulations to meet the needs of their patients (in particular, pediatric patients). Before a centralized electronic compounding database was implemented in the Mission Health System, each satellite or regional pharmacy affiliated with that system had a specific set of formulation records, but no standardized format for those records existed. In this article, we describe the quality control, database platform selection, description, implementation, and execution of our intranet database system, which is designed to maintain, manage, and disseminate nonsterile compounding formulation records in the hospitals and affiliated pharmacies of the Mission Health System. The objectives of that project were to standardize nonsterile compounding formulation records, create a centralized computerized database that would increase healthcare staff members' access to formulation records, establish beyond-use dates based on published stability studies, improve quality control, reduce the potential for medication errors related to compounding medications, and (ultimately) improve patient safety.

Deviation from Berry's adiabatic geometric phase in a [sup 131]Xe nuclear gyroscope  

SciTech Connect

The concept of geometric phase is demonstrated in a nuclear gyroscope using [sup 131]Xe nuclear spins ([ital I]=3/2) as sensors for quantum-phase accumulation. By spatial rotation sub-Hertz splittings due to geometric phases are resolved in nuclear-quadrupole spectra. Deviations from Berry's adiabatic geometric phase appear in the regime of nonadiabatic rotation. The observed frequency splittings are no longer linear in the rotational frequency, as expected from adiabatic rotations, and all possible transitions, namely, six in this partially degenerate spin-3/3 system, are observed experimentally.

A high precision instrument to measure angular and binocular deviation introduced by aircraft windscreens by using a shadow casting technique  

NASA Astrophysics Data System (ADS)

Objects viewed through transparent sheets with residual non-parallelism and irregularity appear shifted and distorted. This distortion is measured in terms of angular and binocular deviation of an object viewed through the transparent sheet. The angular and binocular deviations introduced are particularly important in the context of aircraft windscreens and canopies as they can interfere with decision making of pilots especially while landing, leading to accidents. In this work, we have developed an instrument to measure both the angular and binocular deviations introduced by transparent sheets. This instrument is especially useful in the qualification of aircraft windscreens and canopies. It measures the deviation in the geometrical shadow cast by a periodic dot pattern trans-illuminated by the distorted light beam from the transparent test specimen compared to the reference pattern. Accurate quantification of the shift in the pattern is obtained by cross-correlating the reference shadow pattern with the specimen shadow pattern and measuring the location of the correlation peak. The developed instrument is handy to use and computes both angular and binocular deviation with an accuracy of less than +/-0.1 mrad (~0.036 mrad) and has an excellent repeatability with an error of less than 2%.

A neonatal encephalopathy with seizures in standard poodle dogs with a missense mutation in the canine ortholog of ATF2.  

PubMed

Neonatal encephalopathy with seizures (NEWS) is a previously undescribed autosomal recessive disease of standard poodle puppies. Affected puppies are small and weak at birth. Many die in their first week of life. Those surviving past 1 week develop ataxia, a whole-body tremor, and, by 4 to 6 weeks of age, severe generalized clonic-tonic seizures. None have survived to 7 weeks of age. Cerebella from affected puppies were reduced in size and often contained dysplastic foci consisting of clusters of intermixed granule and Purkinje neurons. We used deoxyribonucleic acid samples from related standard poodles to map the NEWS locus to a 2.87-Mb segment of CFA36, which contains the canine ortholog of ATF2. This gene encodes activating transcription factor 2 (ATF-2), which participates in the cellular responses to a wide variety of stimuli. We amplified and sequenced all coding regions of canine ATF2 from a NEWS-affected puppy and identified a T > G transversion that predicts a methionine-to-arginine missense mutation at amino acid position 51. Methionine-51 lies within a hydrophobic docking site for mitogen-activated protein kinases that activate ATF-2 so the arginine substitution is likely to interfere with ATF-2 activation. All 20 NEWS-affected puppies in the standard poodle family were homozygous for the mutant G allele. The 58 clinically normal family members were either G/T heterozygotes or homozygous for the ancestral T allele. There are no previous reports of spontaneous ATF2 mutations in people or animals; however, atf2-knockout mice have cerebellar lesions that are similar to those in puppies with NEWS. PMID:18074159

Search for the standard model Higgs boson in the H ? ZZ ? 2 ?2 ? channel in pp collisions at sqrt {text{s}} = {7}{text{TeV}}  

NASA Astrophysics Data System (ADS)

A search for the standard model Higgs boson in the H ? ZZ ? 2 ?2 ? decay channel, where ? = e or ?, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 fb-1. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.

Low-temperature heat capacities and standard molar enthalpy of formation of pyridine-2,6-dicarboxylic acid  

NASA Astrophysics Data System (ADS)

This paper reports that the low-temperature heat capacities of pyridine-2,6-dicarboxylic acid were measured by a precision automatic calorimeter over a temperature range from 78 K to 380 K. A polynomial equation of heat capacities as a function of temperature was fitted by the least-squares method. Based on the fitted polynomial, the smoothed heat capacities and thermodynamic functions of the compound relative to the standard reference temperature 298.15 K were calculated and tabulated at intervals of 5 K. The constant-volume energy of combustion of the compound was determined by means of a precision rotating-bomb combustion calorimeter. The standard molar enthalpy of combustion of the compound was derived from the constant-volume energy of combustion. The standard molar enthalpy of formation of the compound was calculated from a combination of the datum of the standard molar enthalpy of combustion of the compound with other auxiliary thermodynamic quantities through a Hess thermochemical cycle.

Frequency measurements of saturated-fluorescence-stabilized CO2 laser lines: comparison with an OsO4-stabilized CO2 laser standard  

NASA Astrophysics Data System (ADS)

We have used the Villetaneuse saturated absorption spectrometer working in the 10 7m region, referenced to the OsO4 frequency grid, to test the performance of the saturated fluorescence method for CO2 laser frequency stabilization. The Allan variance for the saturated-fluorescence-stabilized CO2 laser reached 60 Hz for an integration time of 300 s. We also performed three absolute measurements of CO2 laser frequencies stabilized by the saturated fluorescence method, with a sub-kHz accuracy. We obtained a 1.7 kHz redshift of the CO2 saturated fluorescence lines, which we attribute essentially to pressure. This is in contradiction with the previous observation of a blueshift [K.L. SooHoo, C. Freed, J.E. Thomas, H.A. Haus: Phys. Rev. Lett. 53, 1437 (1984)]. Furthermore, significant deviations of the measured frequencies from the data of Maki et al. [A.G. Maki, C.-C. Chou, K. Evenson, L.R. Zink, J.T. Shy: J. Mol. Spec. 167, 211 (1994)] demonstrate the need for a new calibration of the CO2 frequency grid.

Utilization of AIMS Bossung plots to predict Qz height deviations from nominal  

NASA Astrophysics Data System (ADS)

The ZEISS AIMS™ measurement system has been established for many years as the industry standard for qualifying the printability of mask features based on the aerial image. Typical parameters in determining the printability of a feature are the critical dimension (CD) and intensity deviations of the feature or region of interest with respect to the nominal. While this information is critical to determine if the feature will pass printability, it gives little insight into why the feature failed. For instance, determining if the failure occurs due to the quartz level deviating from that of the nominal height can be problematic. Atomic force microscopy (AFM) is commonly used to determine such physical dimensions as the quartz etch depth or height and sidewall roughness for verification purposes and to provide feedback to front end processes. In addition the AFM is a useful tool in monitoring and providing feedback to the repair engineers as the depth of the repair is one of the many critical parameters which must be controlled in order to have a robust repair process. In collaboration with Photronics nanoFab, we have previously shown the Bossung plot obtained from the AIMS™ aerial image of a feature can be used to determine if the quartz level of a repaired region is above or below the nominal value. This technique can further be used to extract the etch time associated with the nominal quartz height in order to optimize the repair process. The use of this method can be used in lieu of AFM, effectively eliminating the time and effort associated with performing additional metrology steps in a separate system. In this paper we present experimental results supporting the technique and its applicability.

A gravimetric K 2OsCl 6 standard: Application to precise and accurate Os spike calibration  

NASA Astrophysics Data System (ADS)

The Re-Os isotopic system is currently limited as a chronometer because of the lack of accurate gravimetric standards for Os spike calibration and uncertainty of the 187Re half-life, which is also dependent on the accuracy of Os spike calibration. We demonstrate that the concentration of an Os spike can be calibrated accurately to ±0.2%. The accuracy of this calibration was achieved by using a high-purity, stoichiometric, and anhydrous K 2OsCl 6 standard. We show that (NH 4) 2OsCl 6, the standard material used by most other laboratories, is less reliable for Os spike calibration because it is hygroscopic and decomposes during heating. Nebulization and ionization in a plasma at 6500 to 8000 K does not discriminate Os of different oxidation states and chemical forms, allowing Os isotopic ratios in spike-normal mixtures to be equilibrated "on-line" and reproduced at the ˜0.02% level. Multiple isotope dilution measurements reproduce Os concentrations at the 0.04% level. The Os isotopic compositions of the standards determined by multiple collector inductively coupled plasma mass spectrometry are in excellent agreement with that of negative thermal ionization mass spectrometry. A strong linear relationship between instrumental mass fractionation factors (?) for Os and Ir in MC-ICP-MS allows us to determine the isotopic composition of the Os spike with high precision and accuracy. Application of such an accurately calibrated spike is anticipated to reduce the uncertainty of 187Re half-life significantly, thereby increasing the accuracy of the 187Re- 187Os chronometer.

Comparing the sphere anemometer to standard sensors for 2D wind measurements  

NASA Astrophysics Data System (ADS)

The cup anemometers commonly used for wind energy applications are fairly robust, but suffer from several drawbacks like their limited temporal resolution, a systematic overestimation of the wind speed in turbulent flows and the inability to measure the wind direction. While sonic anemometers can measure the wind vector at a higher temporal resolution, they are more fragile and significantly more expensive. Therefore, we propose the sphere anemometer as a robust and highly-resolving alternative to standard anemometers. Designed without wearing parts, the sphere anemometer provides simultaneous wind speed and direction measurements as needed for wind turbine operation especially under challenging conditions such as offshore installation. In our contribution, we introduce the setup of the sphere anemometer which is based on the velocity-dependent deflection of a flexible tube with a sphere mounted atop. The deflection is measured in two dimensions using a light pointer, which allows for the simultaneous determination of wind speed and direction via calibration. Experimental results from wind tunnel measurements with sonic anemometer and sphere anemometer are presented, as well as first comparative measurements from the operation on the nacelle of a near-shore wind turbine.

Standard Review Plan for Environmental Restoration Program Quality Management Plans. Revision 2  

SciTech Connect

The Department of Energy, Richland Operations Office (RL) Manual Environmental Restoration Program Quality System Requirements (QSR) for the Hanford Site, defines all quality requirements governing Hanford Environmental Restoration (ER) Program activities. The QSR requires that ER Program participants develop Quality Management Plans (QMPs) that describe how the QSR requirements will be implemented for their assigned scopes of work. This standard review plan (SRP) describes the ER program participant responsibilities for submittal of QMPs to the RL Environmental Restoration Division for review and the RL methodology for performing the reviews of participant QMPS. The SRP serves the following functions: acts as a guide in the development or revision of QMPs to assure that the content is complete and adequate; acts as a checklist to be used by the RL staff in their review of participant QMPs; acts as an index or matrix between the requirements of the QSR and implementing methodologies described in the QMPs; decreases the time and subjectivity of document reviews; and provides a formal, documented method for describing exceptions, modifications, or waivers to established ER Program quality requirements.

Fatigue in the forearm resulting from low-level repetitive ulnar deviation.  

PubMed

This study measured low-frequency fatigue (LFF) in the extensor carpi ulnaris (ECU) muscle while workers completed a repetitive ulnar deviation task. Using a repeated measures design, 10 healthy women participated in three conditions, each lasting 2 consecutive days: a control condition in which subjects remained inactive, and two repetitive work conditions involving repeated ulnar deviation of the wrist at 20 and 25 repetitions per minute at individual workloads deemed acceptable for 8 hours through a psychophysical protocol. LFF of the ECU muscle and self-reported levels of fatigue were recorded eight times throughout the control and workdays before (time 0), during (2, 4.25, 6.75, 8 hours), and after (9, 10, and 11 hours) exposure. The ratio of the isometric force produced by electrical stimulus at 20 pulses per second (pps) to the isometric force produced by 50 pps provided the measure of LFF. The ratios were lower on workdays compared with the control days, indicating the presence of LFF during repetitive work. During repetitive work the ratios decreased during the day, indicating the muscles fatigued as the day progressed. The psychophysically determined workloads, although not creating noticeable discomfort to the subjects, were high enough to create low levels of muscle fatigue. PMID:14674796

Deviations from tri-bimaximal neutrino mixing using type II seesaw  

NASA Astrophysics Data System (ADS)

We study the possibility of generating deviations from tri-bimaximal (TBM) neutrino mixing to explain the non-zero reactor mixing angle within the framework of both type I and type II seesaw mechanisms. The type I seesaw term gives rise to the ?-? symmetric TBM pattern of neutrino mass matrix as predicted by generic flavor symmetry models like A4 whereas the type II seesaw term gives rise to the required deviations from TBM pattern to explain the non-zero ?13. Considering extremal values of Majorana CP phases such that the neutrino mass eigenvalues have the structure (m1,-m2,m3) and (m1,m2,m3), we numerically fit the type I seesaw term by taking oscillation as well as cosmology data and then compute the predictions for neutrino parameters after the type II seesaw term is introduced. We consider a minimal structure of the type II seesaw term and check whether the predictions for neutrino parameters lie in the 3? range. We also outline two possible flavor symmetry models to justify the minimal structure of the type II seesaw term considered in the analysis.

Detecting deviations from metronomic timing in music: effects of perceptual structure on the mental timekeeper.  

PubMed

The detectability of a deviation from metronomic timing--of a small local increment in interonset interval (IOI) duration--in a musical excerpt is subject to positional biases, or "timing expectations," that are closely related to the expressive timing (sequence of IOI durations) typically produced by musicians in performance (Repp, 1992b, 1998c, 1998d). Experiment 1 replicated this finding with some changes in procedure and showed that the perception-performance correlation is not the result of formal musical training or availability of a musical score. Experiments 2 and 3 used a synchronization task to examine the hypothesis that participants' perceptual timing expectations are due to systematic modulations in the period of a mental timekeeper that also controls perceptual-motor coordination. Indeed, there was systematic variation in the asynchronies between taps and metronomically timed musical event onsets, and this variation was correlated both with the variations in IOI increment detectability (Experiment 1) and with the typical expressive timing pattern in performance. When the music contained local IOI increments (Experiment 2), they were almost perfectly compensated for on the next tap, regardless of their detectability in Experiment 1, which suggests a perceptual-motor feedback mechanism that is sensitive to subthreshold timing deviations. Overall, the results suggest that aspects of perceived musical structure influence the predictions of mental timekeeping mechanisms, thereby creating a subliminal warping of experienced time.

GTA weld penetration and the effects of deviations in machine variables  

SciTech Connect

Analytical models for predicting the temperature distribution during GTA welding are reviewed with the purpose of developing a procedure for investigating the effects of deviations in machine parameters. The objective was to determine the accuracy required in machine settings to obtain reproducible results. This review revealed a wide range of published values (21 to 90%) for the arc heating efficiency. Low values (21 to 65%) were associated with evaluation of efficiency using constant property conduction models. Values from 75 to 90% were determined from calorimetric type measurements and are applicable for more accurate numerical solution procedures. Although numerical solutions can yield better overall weld zone predictions, calculations are lengthy and complex. In view of this and the indication that acceptable agreement with experimental measurements can be achieved with the moving-point-source solution, it was utilized to investigate the effects of deviations or errors in voltage, current, and travel speed on GTA weld penetration. Variations resulting from welding within current goals for voltage (+-0.1 V), current (+-3.0 A), and travel speed (+-2.0%) were found to be +-2 to 4%, with voltage and current being more influential than travel speed.

Search for the standard model Higgs boson at the LEP2 collider near sqrt(s)=183 GeV  

NASA Astrophysics Data System (ADS)

During 1997 the ALEPH experiment at LEP gathered 57 pb-1 of data at centre-of-mass energies near 183 GeV. These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction e+e--->HZ. No evidence of a signal is found in the data; seven events are selected, in agreement with the expectation of 7.2 events from background processes. This observation results in an improved lower limit on the mass of the Higgs boson: mH>87.9 GeV/c2 at 95% confidence level.

Enhancement of cemented waste forms by supercritical CO{sub 2} carbonation of standard portland cements  

SciTech Connect

We are conducting experiments on an innovative transformation concept, using a traditional immobilization technique, that may significantly reduce the volume of hazardous or radioactive waste requiring transport and long-term storage. The standard practice for the stabilization of radioactive salts and residues is to mix them with cements, which may include additives to enhance immobilization. Many of these wastes do not qualify for underground disposition, however, because they do not meet disposal requirements for free liquids, decay heat, head-space gas analysis, and/or leachability. The treatment method alters the bulk properties of a cemented waste form by greatly accelerating the natural cement-aging reactions, producing a chemically stable form having reduced free liquids, as well as reduced porosity, permeability and pH. These structural and chemical changes should allow for greater actinide loading, as well as the reduced mobility of the anions, cations, and radionuclides in aboveground and underground repositories. Simultaneously, the treatment process removes a majority of the hydrogenous material from the cement. The treatment method allows for on-line process monitoring of leachates and can be transported into the field. We will describe the general features of supercritical fluids, as well as the application of these fluids to the treatment of solid and semi-solid waste forms. some of the issues concerning the economic feasibility of industrial scale-up will be addressed, with particular attention to the engineering requirements for the establishment of on-site processing facilities. Finally, the initial results of physical property measurements made on portland cements before and after supercritical fluid processing will be presented.

Computing the compliance of physician drug orders with guidelines using an OWL2 reasoner and standard drug resources.  

PubMed

Assessing the conformity of a physician's prescription to a given recommended prescription is not obvious since both prescriptions are expressed at different levels of abstraction and may concern only a subpart of the whole order. Recent formalisms (OWL2) and tools (reasoners) from the semantic web technologies are becoming available to represent defined concepts and to handle classification services. We propose a generic framework based on such technologies, using available standardized drug resources, to compute the compliance of a given drug order to a recommended prescription, such that the subsumption relationship yields the conformity relationship between the order and the recommendation. The ATC drug classification has been used as a local ontology. The method has been successfully implemented for arterial hypertension management for which we had a sample of antihypertensive orders. However, supplemental standardized drug knowledge is needed to correctly compare drug orders to recommended orders. PMID:21893802

Phase 2 Study of Ceftaroline versus Standard Therapy in Treatment of Complicated Skin and Skin Structure Infections?  

PubMed Central

Ceftaroline, the bioactive metabolite of ceftaroline fosamil (previously PPI-0903, TAK-599), is a broad-spectrum cephalosporin with potent in vitro activity against multidrug-resistant gram-positive aerobic pathogens, including methicillin-resistant Staphylococcus aureus. A randomized, observer-blinded study to evaluate the safety and efficacy of ceftaroline versus standard therapy in treating complicated skin and skin structure infections (cSSSI) was performed. Adults with cSSSI, including at least one systemic marker of inflammation, were randomized (2:1) to receive intravenous (i.v.) ceftaroline (600 mg every 12 h) or i.v. vancomycin (1 g every 12 h) with or without adjunctive i.v. aztreonam (1 g every 8 h) for 7 to 14 days. The primary outcome measure was the clinical cure rate at a test-of-cure (TOC) visit 8 to 14 days after treatment. Secondary outcomes included the microbiological success rate (eradication or presumed eradication) at TOC and the clinical relapse rate 21 to 28 days following treatment. Of 100 subjects enrolled, 88 were clinically evaluable; the clinical cure rate was 96.7% (59/61) for ceftaroline versus 88.9% (24/27) for standard therapy. Among the microbiologically evaluable subjects (i.e., clinically evaluable and having had at least one susceptible pathogen isolated at baseline), the microbiological success rate was 95.2% (40/42) for ceftaroline versus 85.7% (18/21) for standard therapy. Relapse occurred in one subject in each group (ceftaroline, 1.8%; standard therapy, 4.3%). Ceftaroline exhibited a very favorable safety and tolerability profile, consistent with that of marketed cephalosporins. Most adverse events from ceftaroline were mild and not related to treatment. Ceftaroline holds promise as a new therapy for treatment of cSSSI and other serious polymicrobial infections.

Supercontinuum generation in the range 1.6 - 2.4 {mu}m using standard optical fibres  

SciTech Connect

Experimental evidence is presented that standard optical fibres can be used to efficiently convert nanosecond pulses at 1.59 {mu}m to a supercontinuum in the range 1.6 - 2.4 {mu}m. The highest efficiency of conversion to wavelengths above 2 {mu}m, 38%, has been offered by a multimode graded-index fibre. The spectral density of average power in the range 2 - 2.35 {mu}m in this fibre is about 1 mW nm{sup -1} and that of peak power is about 10 W nm{sup -1}. In all the fibres studied, the practical long-wavelength limit of generation is 2.35 {mu}m.

Application of a solid electrolyte CO(2) sensor for the analysis of standard volatile organic compound gases.  

PubMed

Preparation and analysis of standard VOC (volatile organic compound) gases are needed when developing and evaluating the performance of analytical methods or instruments to detect VOCs. In this study, we designed and developed a simple system for the analysis of VOCs based on their decomposition into CO(2) by a combustion catalyst and their subsequent detection using a solid electrolyte CO(2) sensor. In this sensor, NASICON (Na(3)Si(2)Zr(2)PO(4); Na(+) conductor) and binary carbonate (Li(2)CO(3)-BaCO(3)) were used as the solid electrolyte and the sensing layer, respectively. This developed system proved to be effective in determining the concentrations of standard gases, including VOCs (ethanol, formaldehyde, and toluene), CO, and hydrocarbons in parts per million concentrations (10-500 ppm). The system also could continuously monitor the variations in ethanol vapors prepared by a diffusion method where liquid ethanol was heated at 25 and 50 degrees C. The advantages and limitations of our developed analytical system are also discussed. PMID:20337430

Oxidation photochemistry in the Southern Atlantic boundary layer: unexpected deviations of photochemical steady state  

NASA Astrophysics Data System (ADS)

Ozone (O3) is a photochemical oxidant, an air pollutant and a greenhouse gas. As the main precursor of the hydroxyl radical (OH) it strongly affects the oxidation power of the atmosphere. The remote marine boundary layer (MBL) is considered an important region in terms of chemical O3 loss; however surface-based atmospheric observations are sparse and the photochemical processes are not well understood. To investigate the photochemistry under the clean background conditions of the Southern Atlantic Ocean, ship measurements of NO, NO2, O3, JNO2, J(O1D), HO2, OH, ROx and a range of meteorological parameters were carried out. The concentrations of NO and NO2 measured on board the French research vessel Marion-Dufresne (28° S-57° S, 46° W-34° E) in March 2007, are among the lowest yet observed. The data is evaluated for consistency with photochemical steady state (PSS) conditions, and the calculations indicate substantial deviations from PSS (?>1). The deviations observed under low NOx conditions (5-25 pptv) demonstrate a remarkable upward tendency in the Leighton ratio (used to characterize PSS) with increasing NOx mixing ratio and JNO2 intensity. It is a paradigm in atmospheric chemistry that OH largely controls the oxidation efficiency of the atmosphere. However, evidence is growing that for unpolluted low-NOx (NO + NO2) conditions the atmospheric oxidant budget is poorly understood. Nevertheless, for the very cleanest conditions, typical for the remote marine boundary layer, good model agreement with measured OH and HO2 radicals has been interpreted as accurate understanding of baseline photochemistry. Here we show that such agreement can be deceptive and that a yet unidentified oxidant is needed to explain the photochemical conditions observed at 40°-60° S over the Atlantic Ocean.
