  3. Obituary: Edward W. Burke, Jr. (1924-2011)

    NASA Astrophysics Data System (ADS)

    Bloomer, Raymond, Jr.

    2011-12-01

    Dr. Edward W. Burke Jr. passed away on June 15, 2011, after suffering a heart attack. Dr. Burke devoted his professional life to the research and teaching of physics and astronomy at King College in Bristol, Tennessee. Edward W. Burke, Jr., was born in Macon, Georgia, on September 16, 1924. He was a Navy veteran, having been commissioned as an ensign in 1944. He served in the Pacific near the end of World War II. He proceeded to complete his undergraduate degree in mathematics from Presbyterian College in 1947 and pursued the M.S. and Ph.D. in physics (1949 and 1954, respectively) at the University of Wisconsin. Under the direction of Professor Julian Mack, his thesis was titled "Isotope Shift in the Spectra of Boron." Although he did research in atomic spectra in the early part of his career, his interest in astronomy and variable stars in particular were his primary interests during his long academic career. Dr. Burke began his illustrious career at King College in 1949. He initiated the astronomy program there in 1950, included constructing a 12.5 inch Newtonian telescope, homemade as was most everything in those days. Many of his students learned about photometry at the Burke Observatory on the college campus. Burke was known for his trips to the Kitt Peak and Lowell observatories accompanied by undergraduate students on his trips, all of which were made by automobile which he preferred over flying. His initial interest in Ap stars later broadened into variable and especially eclipsing binary stars. His motivation was maintained by his desire to have his students experience basic research and to spark their interest in advanced degrees. Numerous students achieved advanced science and medical degrees because of Burke's encouragement and mentoring. In 1959, Dr. Burke was awarded a Fulbright professorship and traveled to Chile where he taught physics for a year in the Engineering School at the University of Chile in Santiago. He worked to establish a physics

  4. Diffusional falsification of kinetic constants on Lineweaver-Burk plots.

    PubMed

    Ghim, Y S; Chang, H N

    1983-11-07

    The effect of mass transfer resistances on the Lineweaver-Burk plots in immobilized enzyme systems has been investigated numerically and with analytical approximate solutions. While Hamilton, Gardner & Colton (1974) studied the effect of internal diffusion resistances in planar geometry, our study was extended to the combined effect of internal and external diffusion in cylindrical and spherical geometries as well. The variation of Lineweaver-Burk plots with respect to the geometries was minimized by modifying the Thiele modulus and the Biot number with the shape factor. Especially for a small Biot number all the three Lineweaver-Burk plots fell on a single line. As was discussed by Hamilton et al. (1974), the curvature of the line for large external diffusion resistances was small enough to be assumed linear, which was confirmed from the two approximate solutions for large and small substrate concentrations. Two methods for obtaining intrinsic kinetic constants were proposed: First, we obtained both maximum reaction rate and Michaelis constant by fitting experimental data to a straight line where external diffusion resistance was relatively large, and second, we obtained Michaelis constant from apparent Michaelis constant from the figure in case we knew maximum reaction rate a priori.

  5. Triaxial Burke-Schumann Flames with Applications to Flame Synthesis

    NASA Technical Reports Server (NTRS)

    Chao, B. H.; Axelbaum, R. L.; Gokoglu, Suleyman (Technical Monitor)

    2000-01-01

    The problem of a flame generated by three coaxial flows is solved by extending the Burke-Schumann methodology to include a third stream. The solution is particularly relevant to flame synthesis wherein multiple tubes are often employed either to introduce inert as a diffusion barrier or to introduce more than two reactants. The general problem is solved where the inner and outer tubes contain reactants and the middle tube contains either an inert or a third reactant. Relevant examples are considered and the results show that the triaxial Burke-Schumann flame can be substantially more complicated than the traditional Burke-Schumann flame. When the middle flow is inert the flame temperature is no longer constant but increases axially, reaching a maximum at the flame centerline. At the exit the flame does not sit on the tube exit but instead resides between the inner and outer tubes, resulting in an effective barrier for particle build-up on the burner rim. For the case of a third reactant in the middle flow, synthesis chemistry where the inner reaction is endothermic and the outer reaction is exothermic is considered. In addition to showing the flame temperature and flame shape, the results identify conditions wherein reaction is not possible due to insufficient heat transfer from the outer flame to support the inner flame reaction.

  13. Structure and Stability of Burke-Schumann Diffusion Flames

    NASA Technical Reports Server (NTRS)

    Lee, Yong G.; Chen, Lea-Der; Brooker, John E.; Stocker, Dennis P.

    1997-01-01

    The general goal of this NASA Grant is twofold: to improve our understanding of (1) the influence of buoyancy on the stability and structure of Burke-Schumann type diffusion flames, and (2) the effects of buoyancy on vortex-flame interactions in co-flow diffusion flames. A numerical code with a higher order accuracy for spatial discretization is developed in this project for simulation of time-dependent diffusion flames by Sheu and Sheu and Chen, and an extended reduced mechanism is incorporated for prediction of methane oxidation and NO(x)(NO, NO2, and N2O) formation and emission from methane Burke-Schumann diffusion flame (BSDF) as reported in Sheu, and Sheu and Chen. Initial investigation of vortex and flame interaction within the context of fast chemistry is reported. Experiments are conducted in reduced pressure to study the lift-off and stabilization of methane-fueled BSDF in reduced buoyancy environments due to reduced pressure. Measurements of temperature and species concentrations are made in normal and reduced pressure environments to study the effects of buoyancy on the structure of BSDF, and will be reported in this paper. To study the buoyancy effects on the lift-off and stabilization of methane-fueled jet diffusion flames in coflowing air, a glovebox investigation, Enclosed Laminar Flames (ELF), has been proposed and approved for space-based testing on the fourth United States Microgravity Payload (USMP-4) mission, scheduled for October 1997. A brief description of the ELF investigation is also presented.

  14. Dynamic response of a pulsed Burke-Schumann diffusion flame

    NASA Technical Reports Server (NTRS)

    Sheu, Jyh-Cherng; Stocker, Dennis P.; Chen, Lea-Der

    1995-01-01

    Turbulent flames are often envisioned as an ensemble of random vortices interacting with the combustion process. A better understanding of the vortex-flame interactions therefore would be useful in improving the modeling of turbulent diffusion flames. Substantial simplification may be made by investigating controlled interactions in a laminar flame, as opposed to random interactions in a turbulent flame. The general goals of the research project are to improve our understanding of (1) the influence of buoyancy on co-flow diffusion flames and (2) the effects of buoyancy on vortex-flame interactions in co-flow diffusion flames. As a first step toward objective (2), we conducted a joint experimental and numerical investigation of the vortex-flame interaction. Vortices were produced by mechanically pulsing the fuel flow at a low frequency, e.g., 10 Hz. Experiments were conducted using a nonflickering Burke-Schumann flame in both microgravity (mu-g) and normal gravity (1g) as a means of varying the buoyant force without modification of the pressure (i.e., density). The effects of buoyant convection may then be determined by a comparison of the mu-g and 1g results. The mu-g results may also reveal the important mechanisms which are masked or overwhelmed by buoyant convection in 1g. A numerical investigation was conducted using a validated, time-accurate numerical code to study the underlying physics during the flame interaction and to assist the interpretation of the experimental results.

  15. Selections of reality: applying Burke's dramatism to a harm reduction program.

    PubMed

    Järvinen, Margaretha; Miller, Gale

    2014-09-01

    Kenneth Burke's dramatistic perspective is applied to accounts told by staff members working in methadone maintenance treatment centres in Copenhagen, Denmark. As a harm reduction strategy, methadone maintenance is designed to reduce the costs and dangers of chronic long-term drug use by providing substitution (methadone) treatment to users. Burke's dramatistic perspective calls attention to the recurring relationships among rhetorical elements within accounts of social reality. The elements form a pentad: scene, purpose, agent, agency and acts. Our analysis examines how the ideal of governmentality is constructed by staff members to justify and criticize the operations of the Copenhagen methadone maintenance program. For Burke, social criticism involves rearranging pentadic elements to produce new meanings and justify alternative actions. We discuss how Burke's perspective might be developed by sociologists as a critical dramatism of social policies and programs.

  16. Effect of mass transfer resistance on the Lineweaver-Burk plots for flocculating microorganisms.

    PubMed

    Ngian, K F; Lin, S H; Martin, W R

    1977-12-01

    It is shown that the mass transfer resistance can significantly distort the linearity of the Lineweaver-Burk plot of the kinetic data for a microbial culture which forms aggregates. For small flocs, the linearity of the Lineweaver-Burk plot is largely retained, but a different slope and intercept will be obtained compared with flocs free from mass transfer resistance. For large flocs, the Lineweaver-Burk plot shows pronounced curvature at high limiting substrate concentrations. Hence, if the true intrinsic kinetic parameters are to be extracted from a highly flocculating microbial culture, sufficient agitation has to be provided to remove the effect of mass transfer resistance. If the behavior of the flocculating microbial culture is to be explored, additional values for some physical parameters, such as the effective diffusion coefficient of the substrate in floc, the floc density, and the mean floc radius, are needed.

  17. A detailed numerical investigation of Burke-Schumann gaseous and spray flames

    NASA Technical Reports Server (NTRS)

    Mawid, M. A.; Aggarwal, S. K.

    1991-01-01

    The classical Burke-Schumann gaseous diffusion flame, and the effect of introducing fuel in the form of liquid sprays are investigated numerically. The time-dependent two-dimensional, axisymmetric conservation equations are solved for the gas phase. A Lagrangian approach is used for the dispersed phase. The chemical reactions are modeled through the one-step global reaction scheme. The numerical results show that the computed flame structure is significantly different from that given by the analytical solution. The computed flame is about 15 percent longer and 5 percent narrower than the classical Burke-Schumann flame. The predicted flame shape is, however, in better agreement with experimental observations than the Burke-Schumann flame. The effects of introducing liquid sprays is found to produce thinner and longer flames than its counterpart gaseous flame. A detailed comparison of the structures of gaseous and spray flames is made, and the differences are discussed.

  6. Lineweaver-Burk, Hanes, Eadie-Hofstee and Dixon plots in non-steady-state situations.

    PubMed

    Frère, J M; Leyh, B; Renard, A

    1983-04-07

    Lineweaver-Burk, Hanes, Eadie-Hofstee and Dixon plots can only be used when a true initial rate is measured. Despite the fact that this point has often been stressed, it is far too often ignored in favour of restricting the assay time to one where low amounts of substrate are used. When one or several irreversible and slow steps occur with an inactivator during the incubation of a ternary enzyme-substrate-inactivator mixture, the rate of the enzyme-catalysed reaction progressively decreases. Even under these conditions, the present computer simulations investigations show that apparently linear Lineweaver-Burk, Hanes, Eadie-Hofstee and Dixon graphs can be obtained when the amount of product formed is mistakenly assumed to represent the true initial rate. Moreover, the observed pattern can change with time, going for instance from non-competitive to competitive. "Ki's" measured under these conditions also vary with time and bear little relationship to the true constants involved in the interaction.

  7. Factors related to establishment of Prosopis caldenia Burk. seedlings in central rangelands of Argentina

    NASA Astrophysics Data System (ADS)

    de Villalobos, A. E.; Peláez, D. V.; Elia, O. R.

    2005-03-01

    Prosopis caldenia Burk. is one of the woody species that is increasing in abundance due to poor grazing management in the semi-arid phytogeographic region of central Argentina, commonly known as the Caldenal. The objective of this study was to evaluate the effect of herbaceous cover, cattle dung, soil disturbance, and water supply on emergence and survival of P. caldenia seedlings on sites with different grazing histories: (i) a site exposed to long-term continuous grazing by cattle (grazed site), and (ii) a long-term exclosure to domestic livestock (ungrazed site). Removal of grass cover, addition of cattle dung, and water supply enhanced seedling emergence and survival, especially in the grazed site. Results suggest that factors (direct and indirect) associated with prolonged grazing history markedly affect P. caldenia establishment. This in turn alters the grass-woody plant balance, which might reduce the potential capacity of livestock production in the Caldenal.

    The structural and energetic properties of layered materials present a challenge to density functional theory with common semilocal approximations to the exchange-correlation energy. By combining the most widely used semilocal generalized gradient approximation (GGA), the Perdew-Burke-Ernzerhof (PBE) one, with the revised Vydrov-van Voorhis nonlocal correlation functional (rVV10), both excellent structural and energetic properties of 28 layered materials have been recovered with a judicious parameter selection. We term the resulting functional PBE+rVV10L, with the "L" indicating that it is for layered materials. Such a combination is not new, and only involves refitting a single global parameter. However, the resulting excellent accuracy suggests such a dispersion-corrected PBE for many aspects of theoretical studies on layered materials. For comparison, we also present the results for PBE+rVV10 where the parameter is determined by 22 interaction energies between molecules.

    1999-09-21

    The Burke County Clarke Road Municipal Solid Waste Landfill (MSWL) opened in 1975 and is still in operation. This landfill has two areas which accept waste, one cell for municipal and the other for construction and demolition waste. The Georgia Environmental Protection Division (EPD) and the consultant for Burke County, Tribble and Richardson, Inc. (T and R) collected drinking-water well samples on May 12, 1997, at seven residences in the vicinity of the landfill. EPD asked the Georgia Division of Public Health (GDPH) to conduct a public health investigation at the Clarke Road MSWL in Waynesboro, Georgia. EPD is concerned about possible adverse health effects caused by past, present, and future exposure to environmental contamination from the landfill. GDPH classifies this site as no apparent public health hazard. Discussions of exposure pathways, specific contaminants, and conclusions about the risk posed to residents near the landfill are included in this document.

  10. A Burke-Schumann Analysis of Dual-Flame Structure Supported by a Burning Droplet

    Nayagam, V.; Dietrich, D.; Williams, F. A.

    Droplet combustion experiments carried out onboard the International Space Station (ISS), using pure fuels and fuel mixtures, have shown that quasi-steady burning can be sustained by a non-traditional flame configuration, namely a "cool flame" burning in the "partial-burning" regime where both fuel and oxygen leak through the low-temperature controlled flame-sheet. Recent experiments involving large, bi-component fuel (n-decane and hexanol, 50/50 by volume) droplets at elevated pressures show that the visible, hot flame becomes extremely weak while the burning rate remains relatively high, suggesting the possibility of simultaneous presence of "cool" and "hot" flames of roughly equal importance. The radiant output from these bi-component droplets is relatively high and cannot be accounted for only by the presence of a visible hot-flame. In this analysis we explore the theoretical possibility of a dual-flame structure, where one flame lies close to the droplet surface called the "cool-flame," and other farther away from the droplet surface, termed the "hot-flame." A Burke-Schumann analysis of this dual-structure seems to indicate such flame structures are possible over a narrow range of initial conditions. Theoretical results can be compared against available experimental data for pure and bi-component fuel droplet combustion to test how realistic the model may be.

  11. Depositional model for Rival and Midale subintervals (Mississippian), north-central Burke County, North Dakota

    Harris, T.L.

    1988-07-01

    The Rival and Midale subintervals (Charles Formation, Upper Mississippian), north-central Burke County, North Dakota, represent two relative sea level fluctuations. Updip (northeast), the Rival subinterval contains fine to medium-bedded and chicken-wire anhydrite with interbedded algal bindstone that was deposited on supratidal flats. Basinward (southwest), the lithology changes to oncolitic, peloidal, intraclastic grainstone/packstone that was deposited in intertidal and subtidal restricted lagoonal environments. Evaporites precipitated in the sediment of the intertidal to shallow subtidal restricted lagoonal environment. Overlying the Rival subinterval is skeletal wackestone and packstone of the lower Midale subinterval. The presence of normal-marine fauna (crinoids, brachiopods, trilobites, rugose and tabulate coral) indicates a significant relative sea level transgression occurred following deposition of the Rival. The middle and upper Midale subinterval consists of intensely burrowed dolowackestone and dolomudstone that contain a less diversified faunal assemblage. Overlying the Midale carbonates is a transitional zone of calcareous shale and dolomite that grades upward into mottled (burrowed.) and finely laminated microgranular dolomite and anhydrite. The upper Midale section represents a relative sea level regression (shoreline progradation). Updip (northeast) reservoirs produce from the Midale carbonates, which are sealed laterally and vertically by calcarous shale and microgranular dolomitic anhydrite of the Midale Evaporite. Downdip (southwest), the Rival produces from porous grainstone, which is sealed laterally by intertidal/supratidal carbonates and evaporites, resulting in a stratigraphic trap. Vuggy and intergranular porosity are the major porosity types in the Rival grainstone, and moldic and intercrystalline porosity are dominant in the Midale dolowackestone.

    Six geologic units are recognized in the Cretaceous and the Paleocene sediments of eastern Burke and Screven Counties in Georgia on the basis of lithologic, geophysical, and paleontologic data collected from three continuously cored testholes in Georgia and one testhole in South Carolina. The six geologic units are separated by regional unconformities and are designated from oldest to youngest as the Cape Fear Formation, the Middendorf Formation, the Black Creek Group (undivided), and the Steel Creek Formation in the Upper Cretaceous section, and the Ellenton and the Snapp Formations in the Paleocene section. The geologic units provide a spatial and temporal framework for the identification and correlation of a basal confining unit beneath the Midville aquifer system and five aquifers and five confining units in the Dublin and the Midville aquifer systems. The Dublin aquifer system is divided hydrostratigraphically into the Millers Pond, the upper Dublin, and the lower Dublin aquifers. The Midville aquifer system is divided hydrostratigraphically into the upper and the lower Midville aquifers. The fine-grained sediments of the Millers Pond, the lower Dublin, and the lower Midville confining units are nonmarine deposits and are present in the upper part of the Snapp Formation, the Black Creek Group (undivided), and the Middendorf Formation, respectively. Hydrologic data for specific sets of monitoring wells at the Savannah River Site in South Carolina and the Millers Pond site in Georgia confirm that these three units are leaky confining units and locally impede vertical ground-water flow between adjacent aquifers. The fine-grained sediments of the upper Dublin and the upper Midville confining units are marine-deltaic deposits of the Ellenton Formation and the Black Creek Group (undivided), respectively. Hydrologic data confirm that the upper Dublin confining unit regionally impedes vertical ground-water flow on both sides of the Savannah River. The upper Midville

    Burke and Franklin's discovery of radio emissions from Jupiter in 1955 effectively marked the birth of the field of planetary radio astronomy. The discovery was made near Seneca, Maryland using the Department of Terrestrial Magnetism/Carnegie Institution of Washington's Mills Cross Array. Fifty years later there is very little evidence of this 96-acre X-shaped array of dipoles still in existence, nor evidence of any of the other antennas used at this site. The site, now known as the McKee Besher Wildlife Management Area, is owned by the State of Maryland Department of Natural Resources. Radio Jove, a NASA/GSFC education and public outreach project, will recognize the 50th anniversary of this discovery through an historic reenactment using their receiver and dual-dipole array system. Our search through the DTM/CIW archives, our visit to the site to look for evidence of this array, and other efforts at commemorating this anniversary will be described.

  14. Solution to Michaelis-Menten enzyme kinetic equation via undetermined gauge functions: Resolving the nonlinearity of Lineweaver-Burk plot

    Murugan, R.

    2002-09-01

    A composite approximate solution of Michaelis-Menten enzyme kinetic equation, which could describe both transient and slow dynamics, was obtained by ordinary perturbation methods in terms of undetermined gauge functions up to a first-order level. It was found that the zeroth-order perturbation function itself solved the paradox due to steady-state approximation and predicted well the maximum enzyme-substrate complex ([ES]max) and time tm to attain it. Extensive kinetic simulations using a chemical kinetic simulator proved the validity of these results. A comparison between simulated and predicted results showed that error in the prediction of tm was negligible when perturbation parameter falls in the range of (0<ɛ≪1). Apart from these, also the effect of transient dynamics on the linearity of Lineweaver-Burk plot (especially near the origin) has been explained.

  15. A theoretical discussion of the use of the Lineweaver-Burk plot to estimate kinetic parameters of intestinal transport in the presence of unstirred water layers.

    1981-09-01

    Transport of a solute molecule from the bulk phase in the intestinal lumen into the mucosal cells is determined by the rate of movement of the solute molecule across two barriers, the unstirred water layers (UWL) and the microvillus membrane. Failure to account for the effect of the resistance offered by the UWL introduces significant errors into the estimate of kinetic constants of carrier-mediated transport, and these errors may be further magnified by the use of the Lineweaver-Burk plot. This study was under taken to determine use of this plot under conditions that depict the effect of varying the effective resistance of the UWL, the distribution of transport sites along the villus (fn), the passive permeability coefficient (P), the maximal transport rate (Jdm), and the Michaelis constant (Km). Theoretical curves derived from a new equation demonstrate that (1) the Lineweaver-Burk plot is linear under only a limited number of conditions, and even then may lead to serous over- or under-estimation of Jdm and Km; (2) failure to correct for passive permeation may give rise to additional quantitative discrepancies between the true and apparent values of Jdm and Km; and (3) the qualitative characteristics of a carrier-mediated intestinal transport system may be ascertained only after correction for the contribution of passive permeation, and after correction for the effective resistance of the UWL.

    2013-01-01

    The hydrogeology and water quality of the Dublin and Midville aquifer systems were characterized in the City of Waynesboro area in Burke County, Georgia, based on geophysical and drillers’ logs, flowmeter surveys, a 24-houraquifer test, and the collection and chemical analysis of water samples in a newly constructed well. At the test site, the Dublin aquifer system consists of interlayered sands and clays between depths of 396 and 691 feet, and the Midville aquifer system consists of a sandy clay layer overlying a sand and gravel layer between depths of 728 and 936 feet. The new well was constructed with three screened intervals in the Dublin aquifer system and four screened intervals in the Midville aquifer system. Wellbore-flowmeter testing at a pumping rate of 1,000 gallons per minute indicated that 52.2 percent of the total flow was from the shallower Dublin aquifer system with the remaining 47.8 percent from the deeper Midville aquifer system. The lower part of the lower Midville aquifer (900 to 930 feet deep), contributed only 0.1 percent of the total flow. Hydraulic properties of the two aquifer systems were estimated using data from two wellbore-flowmeter surveys and a 24-hour aquifer test. Estimated values of transmissivity for the Dublin and Midville aquifer systems were 2,000 and 1,000 feet squared per day, respectively. The upper and lower Dublin aquifers have a combined thickness of about 150 feet and the horizontal hydraulic conductivity of the Dublin aquifer system averages 10 feet per day. The upper Midville aquifer, lower Midville confining unit, and lower Midville aquifer have a combined thickness of about 210 feet, and the horizontal hydraulic conductivity of the Midville aquifer system averages 6 feet per day. Storage coefficient of the Dublin aquifer system, computed using the Theis method on water-level data from one observation well, was estimated to be 0.0003. With a thickness of about 150 feet, the specific storage of the Dublin aquifer

    This report provides the results of a detailed Level II analysis of scour potential at structure BURKTH00070016 on Town Highway 7 crossing Dish Mill Brook, Burke, Vermont (figures 1–8). A Level II study is a basic engineering analysis of the site, including a quantitative analysis of stream stability and scour (U.S. Department of Transportation, 1993). Results of a Level I scour investigation also are included in Appendix E of this report. A Level I investigation provides a qualitative geomorphic characterization of the study site. Information on the bridge, gleaned from Vermont Agency of Transportation (VTAOT) files, was compiled prior to conducting Level I and Level II analyses and is found in Appendix D. The site is in the White Mountain section of the New England physiographic province in northeastern Vermont. The 6.0-mi2 drainage area is in a predominantly rural and forested basin. In the vicinity of the study site, the surface cover is forest except on the left bank upstream which is brushland. In the study area, Dish Mill Brook has an incised, sinuous channel with a slope of approximately 0.04 ft/ft, an average channel top width of 40 ft and an average bank height of 6 ft. The channel bed material ranges from sand to boulder with a median grain size (D50) of 94.1 mm (0.309 ft). The geomorphic assessment at the time of the Level I and Level II site visit on August 7, 1995, indicated that the reach was stable. The Town Highway 7 crossing of Dish Mill Brook is a 28-ft-long, two-lane bridge consisting of one 24-foot steel-beam span (Vermont Agency of Transportation, written communication, March 24, 1995). The opening length of the structure parallel to the bridge face is 24.8 ft. The bridge is supported by vertical, concrete abutments with wingwalls. The channel is skewed approximately 35 degrees to the opening while the computed opening-skew-to-roadway is 35 degrees. A scour hole 1.0 ft deeper than the mean thalweg depth was observed along the left and right

    2007-01-01

    The source of ground water to production wells at Vogtle Electric Generation Plant (VEGP), a nuclear power plant in Burke County, Georgia, was simulated under existing (2002) and potential future pumping conditions using an existing U.S. Geological Survey (USGS) MODFLOW ground-water flow model of a 4,455-square-mile area in the Coastal Plain of Georgia and South Carolina. Simulation results for three steady-state pumping scenarios were compared to each other and to a 2002 Base Case condition. The pumping scenarios focused on pumping increases at VEGP resulting from projected future demands and the addition of two electrical-generating reactor units. Scenarios simulated pumping increases at VEGP ranging from 1.09 to 3.42 million gallons per day (Mgal/d), with one of the scenarios simulating the elimination of 5.3 Mgal/d of pumping at the Savannah River Site (SRS), a U.S. Department of Energy facility located across the Savannah River from VEGP. The largest simulated water-level changes at VEGP were for the scenario whereby pumping at the facility was more than tripled, resulting in drawdown exceeding 4-8 feet (ft) in the aquifers screened in the production wells. For the scenario that eliminated pumping at SRS, water-level rises of as much as 4-8 ft were simulated in the same aquifers at SRS. Results of MODFLOW simulations were analyzed using the USGS particle-tracking code MODPATH to determine the source of water and associated time of travel to VEGP production wells. For each of the scenarios, most of the recharge to VEGP wells originated in an upland area near the county line between Burke and Jefferson Counties, Georgia, with none of the recharge originating on SRS or elsewhere in South Carolina. An exception occurs for the scenario whereby pumping at VEGP was more than tripled. For this scenario, some of the recharge originates in an upland area in eastern Barnwell County, South Carolina. Simulated mean time of travel from recharge areas to VEGP wells for the

    1. We had demonstrated (Emaduddin et al., 1995) the blocking effects of the three mammalian dopamine receptor antagonists, (+/-)-SKF83566 (mammalian dopamine D1-like receptor antagonist), (+)-UH232 (D2 and D3-like receptor antagonist) and (+/-)-sulpiride (D2-like receptor antagonist) on the dose (pressure duration)-response curves of dopamine in the three giant neurone types, LVMN (left visceral multiple spike neurone), d-RPeAN (dorsal-right pedal anterior neurone) and v-LCDN (ventral-left cerebral distinct neurone), of Achatina fulica Férussac under voltage clamp. In the present study, we analyzed these data by Lineweaver-Burk plot. 2. Dopamine-induced inward currents (Iin) of the two neurone types, LVMN and d-RPeAN, were blocked by (+/-)-SKF83566 and (+)-UH232 in partly noncompetitive and partly uncompetitive manners. (+/-)-Sulpiride had no effect on these currents. 3. In contrast, dopamine-induced outward current (Iout) of v-LCDN was inhibited competitively by (+/-)-sulpiride and noncompetitively by (+)-UH232. (+/-)-SKF83566 had no effect on this current. 4. Therefore, we consider that the pharmacological features of the dopamine receptors of Achatina neurones are not identical in detail to those of the mammalian dopamine receptors.

    We propose the use of modified Lineweaver-Burk plots for the correct evaluation of Michaelis-Menten parameters in radioactive enzyme assays. A correction factor X for the translation of 1/S0 into 1/S is directly derived from the integrated Michaelis-Menten equation without the need of complicated calculations. In practice, this approach is favorably combined with an isotope dilution method which enhances the reliability of measurements at low substrate concentrations. The usefulness of the theoretical and practical approach is demonstrated in investigations of HMG-CoA reductase present in membrane fractions isolated from radish seedlings. The enzyme in the two main membrane fractions obtained by centrifugation at 16000 X g ( P16000 ) and at 105000 X g ( P105000 ) appears to be independently regulated by phytochrome and by phytohormones. Whereas active phytochrome decreases the apparent V of HMG-CoA reductase in the P105000 without affecting the Km, it increases the apparent Km in the P16000 . Kinetin treatment also results in a higher apparent Km of the enzyme in the P16000 fraction. Gibberellic acid and indoleacetic acid did not exhibit such a clear effect.

    1. Lineweaver-Burk plots for glutamate dehydrogenase, glucose 6-phosphate dehydrogenase and several other enzymes show one or more abrupt transitions between apparently linear sections. These transitions correspond to abrupt increases in the apparent K(m) and V(max.) with increasing concentration of the varied substrate. 2. The generalized reciprocal initial-rate equation for a multi-site enzyme requires several restrictions to be put on it in order to generate such plots. These mathematical conditions are explored. 3. It is shown that the effective omission of a term in the denominator of the reciprocal initial-rate equation represents a minimal requirement for generation of abrupt transitions. This corresponds in physical terms to negative co-operativity followed by positive co-operativity affecting the catalytic rate constant for the reaction. 4. Previous models for glutamate dehydrogenase cannot adequately account for the results. On the other hand, the model based on both negative and positive co-operativity gives a good fit to the experimental points. 5. The conclusions are discussed in relation to current knowledge of the structure and mechanism of glutamate dehydrogenase.

This suggests that ambient condition simulations at rho=1 g/cm(3) will rather describe a supercooled state that is overstructured when compared to liquid water.

    The quality and safety of Panax notoginseng products has become a focus of concern in recent years. Contamination with heavy metals is one of the important factors as to P. notoginseng safety. Cleaning treatments can remove dust, soil, impurities or even heavy metals and pesticide residues on agricultural products. But effects of cleaning treatments on the heavy metal content of P. notoginseng roots have still not been studied. In order to elucidate this issue, the effects of five different cleaning treatments (CK, no treatment; T1, warm water (50°C) washing; T2, tap water (10°C) washing; T3, drying followed by polishing; and T4, drying followed by tap water (10°C) washing) on P. notoginseng roots' heavy metal (Cu, Pb, Cd, As and Hg) contents were studied. The results showed that heavy metal (all five) content in the three parts all followed the order of hair root > rhizome > root tuber under the same treatment. Heavy metal removals were in the order of Hg > As > Pb > Cu > Cd. Removal efficiencies of the four treatments were in the order of T2 > T1 > T3 > T4. Treatments (T1-T4) could decrease the contents of heavy metal in P. notoginseng root significantly. Compared with the requirements of WM/T2-2004, P. notoginseng roots' heavy metal contents of Cu, Pb, As and Hg were safe under treatments T1 and T2. In conclusion, the cleaning process after production was necessary and could reduce the content of heavy metals significantly. Fresh P. notoginseng root washed with warm water (T2) was the most efficient treatment to remove heavy metal and should be applied in production.

  20. Contamination of supplements: an interview with professor Ron Maughan by Louise M. Burke.

    PubMed

    Maughan, Ron

    2004-08-01

    This issue of IJSNEM features two articles related to supplement use by athletes. In one (Morrison et al. 2004), people who undertake regular exercise in a gym were found to report the use of a wide variety of supplements. The other paper (Goel et al. 2004) dealt with one of the issues that a sub-group of athletes need to consider before deciding to take supplements - the risk of a positive drug test if the product contains substances banned by the anti-doping codes under which their sport is conducted. This issue received much publicity earlier in the year when top tennis player Greg Rusedski tested positive for the steroid nandrolone as the result of inadvertent intake via a contaminated supplement. In this article, Professor Ron Maughan, Chair of Sports Nutrition at Loughborough University in the United Kingdom, advisor to the British Olympic team, and co-editor of IJSNEM, provides his insight on this important topic.

    This paper presents the results of recent tests of a new type of sorbent useful for emissions control. The sorbent, referred to as thermally active marble (TAM), comprises a class of naturally-occurring metamorphic calcium carbonates. TAMs break down upon heating in combustors more evenly and with higher reactivity than limestone, resulting in better calcium utilization rates. Use of TAMS may also reduce NOx and CO emissions, excess air consumption and unburned carbon, and also improve combustion efficiency. In a full-scale (90 MW) demonstration comparing TAM to limestone, the Ca/S improved from 2.6 to 1.5 or better. Unburned carbon in fly ash decreased significantly and NOx levels were also reduced.

    O'Neal, Michael Aaron

    2016-09-01

    The 2015 article by Osborn and others entitled 'Lichenometric Dating: Science or Pseudo-Science?' delivers an unprecedented, in-depth critique of the cumulative problems associated with the development and application of lichenometric dating techniques over the past 65 years. Their stated goal is to appraise the validity of numerical ages derived from lichen measurements, but in doing so, they present a broader, systematic deconstruction of current lichenometric dating practices by emphasizing the unreliable, incomparable, and irreproducible results published by many studies. Osborn et al. revisit a few examples where some scientific rigor has been applied to the methodology, but overall, they cast doubt on the usefulness of any lichenometric analysis by revealing a global failure to avoid poor techniques and outcomes, heedless of the caveats stated in past literature.

    In their recent article [1], Chari et al. call attention to the important subject of setting National Ambient Air Quality Standards (NAAQS) to provide requisite protection for public health, including the health of sensitive groups, as specified under the Clean Air Act (73 FR 66965) [2]. The authors focus on consideration of susceptibility to inform policy choices, using lead (Pb)-related neurocognitive effects and children from low socioeconomic status (SES) families in the context of alternative Pb standard levels. Our comments focus on the authors' analysis of the scientific evidence and not on policy. We agree with the authors that the health effects evidence for Pb indicates a role (or roles) for SES-related factors in influencing childhood Pb exposure and associated health effects. We disagree, however, with the authors' interpretation of the literature on SES influence on the shape of the concentration-response (C-R) relationship between children's blood Pb and IQ (e.g., steepness of the slope). We further address aspects of the scientific evidence that are important to the consideration of sensitive populations in the context of the Pb NAAQS, and how the U.S. Environmental Protection Agency (EPA) considered this evidence in setting the Pb NAAQS in 2008.

    A recent study by Burke et al. [Burke M, Miguel E, Satyanath S, Dykema J, Lobell D (2009) Proc Natl Acad Sci USA 106(49):20670-20674] reports statistical evidence that the likelihood of civil wars in African countries was elevated in hotter years. A following study by Buhaug [Buhaug H (2010) Proc Natl Acad Sci USA 107(38):16477-16482] reports that a reexamination of the evidence overturns Burke et al.'s findings when alternative statistical models and alternative measures of conflict are used. We show that the conclusion by Buhaug is based on absent or incorrect statistical tests, both in model selection and in the comparison of results with Burke et al. When we implement the correct tests, we find there is no evidence presented in Buhaug that rejects the original results of Burke et al.

The talk will be illustrated with photographs of his work, including an installation in an Etruscan tomb and one at the port city of Savona in Italy. Mr. Burke sees a romance in science equivalent to that of art, and will argue that the two should not be so resolutely separated.

In March 1829, soon after the crimes came to light and Burke had been found guilty of murder and executed, Wright commented on the case in his diary, describing the practices in the dissection rooms and giving his views on Robert Knox, the teacher who had become his friend.

Extensive natural history information is available and is summarized in several bibliographies and reviews (Sweeny and Poelker 1977, McCord and Cardoza 1982, Boddicker 1983, Anderson 1987, Rolley 1987). The bobcat is a spotted cat with a short white-tipped tail, small dark ear tufts and is about twice the size of the house cat (Felis domesticus) because of the bobcat’s longer bone structure (McCord and Cardoza 1982, Jameson and Peeters 1988). The bobcat weights between 5- 15 kg with males larger than females. TL 700- 1000, T 95-150, E (from crown) 60-75 (Jameson and Peeters 1988).

    Research on adult age differences in language production has traditionally focused on either the production of single words or the properties of language samples. Older adults are more prone to word retrieval failures than are younger adults (e.g., Burke, MacKay, Worthley, & Wade, 1991). Older adults also tend to produce fewer ideas per utterance…

    2006-03-01

    Filled skutterudite antimonides have attracted much interest as a new class of thermoelectric materials. We have determined the electronic structures, optical and thermoelectric propertes of Tl-filled skutterudite CoSb3 by using the highly precise full-potential linearized augmented plane wave (FLAPW) method within the Perdew-Burke-Ernzerhof (PBE) form of the generalized gradient approximation (GGA) to density functional theory. In contrast to the small-gap semiconducting CoSb3, Tl-filled CoSb3 is calculated to be metallic with Tl-sp bands stongly hybridized with all the other elements over the entire energy region. The thermoelectric properties, e.g. the Seebeck coefficient, are evaluated and discussed in terms of the diagonal terms of the optical matrix elements. B.C. Sales, D. Mandrus, and R. K.

  18. Social anxiety, alcohol expectancies, and self-efficacy as predictors of heavy drinking in college students.

    PubMed

    Gilles, Donna M; Turk, Cynthia L; Fresco, David M

    2006-03-01

    Burke and Stephens (1999) [Burke, R.S., Stephens, R.S. Social anxiety and drinking in college students: A social cognitive theory analysis. Clinical Psychology Review, 19, (1999) 513-530.] proposed a social cognitive theory of heavy drinking in college students. According to this theory, alcohol expectancies for social facilitation and self-efficacy for refusing heavy drinking in anxiety-producing social situations moderate the relationship between social anxiety and drinking. In the current study, a significant three-way interaction was observed among social anxiety, expectancies, and self-efficacy when amount and frequency of drinking was the dependent variable. As predicted by the model, socially anxious college students with low self-efficacy for avoiding heavy drinking in social situations and high positive expectancies for social facilitation reported more alcohol consumption than other socially anxious individuals.

  19. On the structure of gaseous confined laminar diffusion flames: Numerical investigation

    NASA Technical Reports Server (NTRS)

    Mawid, M. A.; Bulzan, D. L.; Aggarwal, S. K.

    1993-01-01

    The structure and characteristics of gaseous confined laminar diffusion flames are investigated by numerically solving the time-dependent two-dimensional axisymmetric conservation equations. The numerical model accounts for the important chemical and physical processes involved, including axial diffusion, viscous effects, radial convection, and finite-rate chemistry. The numerical results clearly show that the flame has a finite thickness and leakage of fuel vapor into the flame zone is possible. The effect of heat release is found to induce some radial flow. Predicted flame shape and dimensions are compared to the classical Burke-Schumann flame. The numerically calculated flame is observed to be about 15 percent taller and 5 percent narrower than that of the Burke-Schumann solution under the same conditions.

  20. Howison, the Cramond Murderer, and last person to be hanged and dissected.

    PubMed

    Kaufman, M H

    2000-02-01

    An articulated skeleton in Edinburgh University's Anatomy Museum of "Howison, The Cramond Murderer", shares a show-case with the articulated skeleton of "William Burke, The Murderer". While the murderous activities of William Burke are well known, because of his association and activities with William Hare, and because they sold the bodies of their victims to Dr Robert Knox, the anatomist, little these days is recalled of Howison. He was executed for the murder of a woman in Cramond in December 1831, and was hanged on 21st January 1832. The case is important because he was the last individual executed before the implementation of the Anatomy Act of 1832. Accordingly, under the conditions of the previous Act, of 1752, entitled "An Act for better preventing the horrid Crime of Murder", his body had to be handed across to the surgeons to be "dissected and anatomized", before it could be buried.

    Secondary dystonia encompasses a heterogeneous group with different etiologies. Cerebral palsy is the most common cause. Pharmacological treatment is often unsatisfactory. There are only limited data on the therapeutic outcomes of deep brain stimulation in dyskinetic cerebral palsy. The published literature regarding deep brain stimulation and secondary dystonia was reviewed in a meta-analysis to reevaluate the effect on cerebral palsy. The Burke-Fahn-Marsden Dystonia Rating Scale movement score was chosen as the primary outcome measure. Outcome over time was evaluated and summarized by mixed-model repeated-measures analysis, paired Student t test, and Pearson's correlation coefficient. Twenty articles comprising 68 patients with cerebral palsy undergoing deep brain stimulation assessed by the Burke-Fahn-Marsden Dystonia Rating Scale were identified. Most articles were case reports reflecting great variability in the score and duration of follow-up. The mean Burke-Fahn-Marsden Dystonia Rating Scale movement score was 64.94 ± 25.40 preoperatively and dropped to 50.5 ± 26.77 postoperatively, with a mean improvement of 23.6% (P < .001) at a median follow-up of 12 months. The mean Burke-Fahn-Marsden Dystonia Rating Scale disability score was 18.54 ± 6.15 preoperatively and 16.83 ± 6.42 postoperatively, with a mean improvement of 9.2% (P < .001). There was a significant negative correlation between severity of dystonia and clinical outcome (P < .05). Deep brain stimulation can be an effective treatment option for dyskinetic cerebral palsy. In view of the heterogeneous data, a prospective study with a large cohort of patients in a standardized setting with a multidisciplinary approach would be helpful in further evaluating the role of deep brain stimulation in cerebral palsy. © 2013 Movement Disorder Society.

    In this study, we investigate the use of narrative in online conversations among persons suffering from chronic opiate addiction and evaluate both its positive and negative uses. Illness narratives, as argued by sociologist Arthur Frank and psychiatrist/medical anthropologist Arthur Kleinman, enable patients to give order to life experiences and receive support from others. We wished to explore under what circumstances online support coalesces and breaks apart. The narratives we examined exemplify two topics frequently discussed on the message board: the recovery process and what it means to be 'clean'. To better understand these narratives from a theoretically based approach, we used the work of rhetorical theorist Kenneth Burke. Burke's description of two human motives, suffering and perfection, led us to an understanding of how unification and division happened within the online community. We found that the recovery narrative primarily embodied the author's suffering and, consequently, received support from other members of the message board. The second narrative centered on what it means to be 'clean' through a discussion of the author's desire to court temptation, revealing what Burke calls the rotten nature of perfection. As a result, the author of the narrative provoked disagreements and did not receive support.

  11. Structural and Thermoelectronic Properties of Chalcopyrite MgSiX2 (X = P, As, Sb)

    We have explored the structural, electronic, optical, and mechanical properties of the magnesium-based chalcopyrites MgSiP2, MgSiAs2, and MgSiSb2 using density functional theory with five different generalized gradient approximation (GGA) functionals: Perdew-Wang (1991), Perdew-Burke-Ernzerhof, revised Perdew-Burke-Ernzerhof, modified Perdew-Burke-Ernzerhof for solids, and Armiento-Mattson (2005) as well as the local density approximation. Change of the constituent element from P to Sb significantly affected the lattice constants, elastic constants, and thermal and dielectric properties. Our theoretically computed results are in reasonable agreement with experiments and other theoretical calculations. The electronic band structure results imply that all three considered compounds are semiconductors. MgSiP2 has the highest value of elastic constants, and bulk and shear moduli compared with the other two binary chalcopyrites. Furthermore, the optical response in terms of the dielectric functions, optical reflectivity, refractive index, extinction coefficient, and electron energy loss of the compounds were also investigated in the energy range from 0 eV to 15 eV. The calculated optical results reveal optical polarization anisotropy for all three compounds, making them useful for optoelectronic device applications. Moreover, specific focus is also given to quantify the dependence of various thermal properties on finite pressure/temperature within the quasiharmonic approximation.

  12. Fault control of channel sandstones in Dakota Formation, southwest Powder River basin, Wyoming

    SciTech Connect

    1983-08-01

    The Dakota Formation is an important oil reservoir in the southwestern Powder River basin and adjoining Casper arch. Two fields, Burke Ranch and South Cole Creek, are used as examples to show the depositional environments of the Dakota and to indicate the influence of tectonic control on the distribution of the environments. Burke Ranch field is a stratigraphic trap which produces oil from the upper bench of the Dakota. The environment of deposition of the reservoir, determined by subsurface analysis, is a channel sandstone. South Cole Creek field is a structural-stratigraphic trap which produces from the lower bench of the Dakota. Two distinct facies, a channel and channel margin sandstone, exist at South Cole Creek. At both Burke Ranch and South Cole Creek it can be shown that the Dakota channels were deposited on the downthrown side of faults, which were present during Dakota time and which now are reflected on the surface by drainage patterns. An understanding of the environments of deposition of the Dakota and control of the environments by paleotectonics is necessary for exploration for these prolific reservoirs.

  13. Robert Knox and the anatomy of beauty.

    PubMed

    Neher, Allister

    2011-06-01

    Robert Knox (1791-1862) is typically remembered as the Edinburgh anatomist to whom the murderers Burke and Hare sold the bodies of their victims. This association brought Knox infamy and damaged his life and career. Before the Burke and Hare scandal, Knox was one of the most famous, original and influential anatomists in Britain. He was also something of a dandy with a sophisticated appreciation of the visual arts. His most significant writings on artistic subjects were his books A Manual of Artistic Anatomy and Great Artists and Great Anatomists: A Biographical and Philosophical Study. Knox's interesting and independently minded opinions on the central artistic questions of his day were taken seriously by his contemporaries. His demotion in the official history of anatomy following his involvement with Burke and Hare, however, also removed him from the history of art theory in 19th century Britain. Knox was such a magnetic and impressive figure, though, that he has to be brought back to his era and his era is not complete without him. This paper discusses how Knox's writings on anatomy and biology shaped his contributions to art theory. It is a first step towards returning Knox, the art theorist, to the cultural life of 19th century Britain.

  14. A new multi-wavelength model-based method for determination of enzyme kinetic parameters.

    Lineweaver-Burk plot analysis is the most widely used method to determine enzyme kinetic parameters. In the spectrophotometric determination of enzyme activity using the Lineweaver-Burk plot, it is necessary to find a wavelength at which only the substrate or the product has absorbance without any spectroscopic interference of the other reaction components. Moreover, in this method, different initial concentrations of the substrate should be used to obtain the initial velocities required for Lineweaver-Burk plot analysis. In the present work, a multi-wavelength model-based method has been developed and validated to determine Michaelis-Menten constants for some enzyme reactions. In this method, a selective wavelength region and several experiments with different initial concentrations of the substrate are not required. The absorbance data of the kinetic assays are fitted by non-linear regression coupled to the numeric integration of the related differential equation. To indicate the applicability of the proposed method, the Michaelis-Menten constants for the oxidation of phenanthridine, 6-deoxypenciclovir and xanthine by molybdenum hydroxylases were determined using only a single initial concentration of the substrate, regardless of any spectral overlap.

    Epidemiologic studies have reported that moderate alcohol consumption is inversely associated with the risk of renal cancer. However, there is no information available on the associations in renal cancer subsites. From 1992 to 2010, 477,325 men and women in the European Prospective Investigation into Cancer and Nutrition cohort were followed for incident renal cancers (n = 931). Baseline and lifetime alcohol consumption was assessed by country-specific, validated dietary questionnaires. Information on past alcohol consumption was collected by lifestyle questionnaires. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated from Cox proportional hazard models. In multivariate analysis, total alcohol consumption at baseline was inversely associated with renal cancer; the HR and 95% CI for the increasing categories of total alcohol consumption at recruitment vs. the light drinkers category were 0.78 (0.62-0.99), 0.82 (0.64-1.04), 0.70 (0.55-0.90), and 0.91 (0.63-1.30), respectively, (ptrend = 0.001). A similar relationship was observed for average lifetime alcohol consumption and for all renal cancer subsites combined or for renal parenchyma subsite. The trend was not observed in hypertensive individuals and not significant in smokers. In conclusion, moderate alcohol consumption was associated with a decreased risk of renal cancer.

  16. Structural properties of Alumnum nitride compound

    NASA Astrophysics Data System (ADS)

    Mohammad, R.; Katırcıoğlu, Ş.

    2014-10-01

    Structural properties of Alumnum nitride in wurtzite, zinc-blende and rock-salt phases have been investigated by Full Potential-Linearized Augmented Plane Waves method based on Density Functional Theory within Local Density Approximation and seven Generalized Gradient schemes. It is found that, Alumnum nitride in wurtzite phase is the stable ground state structure and makes a transition to rock-salt phase at a low transition pressure (11.54 GPa). According to present total energy calculations, zinc-blende phase of Alumnum nitride also makes a transition to rock-salt phase, at a low transition pressure (10.17 GPa). Generalized Gradient functionals of Perdew-Wang-Engel-Vosko and Perdew-Burke-Ernzerhof are found to be more successful than other approximations considered in this work for providing the closest values of the structural features, such as, lattice constants, bulk moduli, first order pressure derivatives of bulk moduli and cohesive energies of Alumnum nitride three phases to available experimental ones. Although Generalized Gradient approaches of Perdew-Wang-Engel-Vosko, Perdew-Burke-Ernzerhof, Becke-Perdew-Wang and Perdew-Burke-Ernzerhof (revised) are found to be accurate schemes for elastic constants of rock-salt AlN, only Perdew-Wang-Engel-Vosko and Perdew-Burke-Ernzerhof functionals are observed to be more successful than the other schemes for supplying accurately both C_{11} and C_{12} of zinc-blende Alumnum nitride structure. Perdew-Wang-Engel-Vosko functional is observed to be superior to Perdew-Burke-Ernzerhof for elastic constants of wurtzite Alumnum nitride structure. Elastic constants of wurtzite Alumnum nitride obtained by self Perdew-Wang-Engel-Vosko approach and Martin's transformation calculations in which elastic constants of zinc-blende Alumnum nitride are calculated with Perdew-Wang-Engel-Vosko scheme, are very close to the experimental ones. Hence, functional of Perdew-Wang-Engel-Vosko is decided to be the most accurate approximation

  17. Sensitivity of High-Resolution Simulations of Hurricane Bob (1991) to Planetary Boundary Layer Parameterizations

    NASA Technical Reports Server (NTRS)

    Braun, Scott A.; Tao, Wei-Kuo

    1999-01-01

    The MM5 mesoscale model is used to simulate Hurricane Bob (1991) using grids nested to high resolution (4 km). Tests are conducted to determine the sensitivity of the simulation to the available planetary boundary layer parameterizations, including the bulk-aerodynamic, Blackadar, Medium-RanGe Forecast (MRF) model, and Burk-Thompson boundary-layer schemes. Significant sensitivity is seen, with minimum central pressures varying by up to 17 mb. The Burk-Thompson and bulk-aerodynamic boundary-layer schemes produced the strongest storms while the MRF scheme produced the weakest storm. Precipitation structure of the simulated hurricanes also varied substantially with the boundary layer parameterizations. Diagnostics of boundary-layer variables indicated that the intensity of the simulated hurricanes generally increased as the ratio of the surface exchange coefficients for heat and momentum, C(sub h)/C(sub M), although the manner in which the vertical mixing takes place was also important. Findings specific to the boundary-layer schemes include: 1) the MRF scheme produces mixing that is too deep and causes drying of the lower boundary layer in the inner-core region of the hurricane; 2) the bulk-aerodynamic scheme produces mixing that is probably too shallow, but results in a strong hurricane because of a large value of C(sub h)/C(sub M) (approximately 1.3); 3) the MRF and Blackadar schemes are weak partly because of smaller surface moisture fluxes that result in a reduced value of C(sub h)/C(sub M) (approximately 0.7); 4) the Burk-Thompson scheme produces a strong storm with C(sub h)/C(sub M) approximately 1; and 5) the formulation of the wind-speed dependence of the surface roughness parameter, z(sub 0), is important for getting appropriate values of the surface exchange coefficients in hurricanes based upon current estimates of these parameters.

    Recent studies have suggested that gut symbionts modulate insect development and reproduction. However, the mechanisms by which gut symbionts modulate host physiologies and the molecules involved in these changes are unclear. To address these questions, we prepared three different groups of the insect Riptortus pedestris: Burkholderia gut symbiont-colonized (Sym) insects, Burkholderia-non-colonized (Apo) insects, and Burkholderia-depleted (Sym(Burk-)) insects, which were fed tetracycline. When the hemolymph proteins of three insects were analyzed by SDS-PAGE, the hexamerin-α, hexamerin-β and vitellogenin-1 proteins of Sym-adults were highly expressed compared to those of Apo- and Sym(Burk-)-insects. To investigate the expression patterns of these three genes during insect development, we measured the transcriptional levels of these genes. The hexamerin-β gene was specifically expressed at all nymphal stages, and its expression was detected 4-5 days earlier in Sym-insect nymphs than that in Apo- and Sym(Burk-)-insects. However, the hexamerin-α and vitellogenin-1 genes were only expressed in adult females, and they were also detected 6-7 days earlier and were 2-fold higher in Sym-adult females than those in the other insects. Depletion of hexamerin-β by RNA interference in 2nd instar Sym-nymphs delayed adult emergence, whereas hexamerin-α and vitellogenin-1 RNA interference in 5th instar nymphs caused loss of color of the eggs of Sym-insects. These results demonstrate that the Burkholderia gut symbiont modulates host development and egg production by regulating production of these three hemolymph storage proteins.

    Hymecromone is an important coumarin drug, and carprofen is one of the most important nonsteroidal antiinflammatory drugs (NSAIDs). The present study aims to determine the influence of bovine serum albumin (BSA) on the carprofen-hymecromone interaction. The inhibition of carprofen enantiomers on the UDP-glucuronosyltransferase (UGT) 2B7-catalyzed glucuronidation of hymecromone was investigated in the UGTs incubation system with and without BSA. The inhibition capability of increased by 20% (P < 0.001) of (R)-carprofen after the addition of 0.5% BSA in the incubation mixture. In contrast, no significant difference was observed for the inhibition of (S)-carprofen on UGT2B7 activity in the absence or presence of 0.5% BSA in the incubation system. The Lineweaver-Burk plot showed that the intersection point was located in the vertical axis, indicating the competitive inhibition of (R)-carprofen on UGT2B7 in the incubation system with BSA, which is consistent with the inhibition kinetic type of (R)-carprofen on UGT2B7 in the incubation system without BSA. Furthermore, the second plot using the slopes from the Lineweaver-Burk versus the concentrations of (R)-carprofen showed that the fitting equation was y=39.997x+50. Using this equation, the inhibition kinetic parameter was calculated to be 1.3 μM. For (S)-carprofen, the intersection point was located in the horizontal axis in the Lineweaver-Burk plot for the incubation system with BSA, indicating the noncompetitive inhibition of (S)-carprofen on the activity of UGT2B7. The fitting plot of the second plot was y=24.6x+180, and the inhibition kinetic parameter was 7.3 μM. In conclusion, the present study gives a short summary of BSA's influence on the carprofen enantiomers-hymecromone interaction, which will guide the clinical application of carprofen and hymecromone.

    In the present work, we report the structural and the electronic properties of the alloy Zn1-xSbxTe with x = (0.25%, 0.50% and 0.75%). Ab initio calculations are based upon the density functional theory with generalized gradient approximation and Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional. In our calculations, we found that antimony (Sb) doping in zinc telluride (ZnTe) system introduces some bands which mainly originate from s- and p-states of Te and Sb atom and are primarily responsible for n-type and p-type conductivity.

    1997-01-01

    Compared with other joints, the ligaments of the ankle have not been studied in great detail; consequently relatively little literature exists. The positions of the 3 major bands of the lateral collateral ligament are well known and documented (Schafer et al. 1915; Sarrafian, 1983; McMinn, 1994; Palastanga et al. 1994; Williams et al. 1995). The detailed anatomy of the ligaments is, however, relatively complex with variations of the major bands and several minor additional bands being reported (Sarrafian, 1993; Burks & Morgan, 1994; Rosenberg et al. 1995).

    There is a long history of thought and discussion on the possibilities of astronomical observatories on the Moon. Numerous ideas have been suggested and a variety of concepts have resulted for lunar optical telescopes. This paper reviews some of the ideas and efforts of individuals and working groups including Hershel, Clarke, Malina, Herbig, and Hess; working groups of the 1960s; and recent initiatives of Burke, Burns, and others. The enhanced technologies of the 1980s and 1990s can make past dreams of lunar observatories come to reality in the 21st century.

    A formalism for determining pseudostate wave functions for use in modified close-coupling calculations is presented. Applications to low-energy electron-hydrogen scattering are discussed. The 2p― pseudostate proposed by Damburg and Karule is analyzed using this formalism and a reason for its success is given which is independent of the fact that it fully accounts for the ground-state polarizability of atomic hydrogen. The analysis suggests, in agreement with expectations of Burke and Schey and others, that short-range correlations are more important than long-range polarization in determining the best form of the pseudostates.

    The ground-state properties, electronic structure, magnetic and mechanical properties of cobalt oxide (CoO) and nickel oxide (NiO) are investigated using generalised gradient approximation parameterised by Perdew-Burke-Ernzerhof (GGA-PBE) and GGA-PBE+U formalisms. These oxides are found to be stable in the antiferromagnetic (AFM) state at normal pressure. The computed lattice parameters are in agreement with the experimental and other theoretical works. Pressure-induced magnetic transition from AFM to ferromagnetic (FM) state is predicted in NiO at a pressure of 84 GPa. Both these compounds are found to be mechanically stable in the AFM state at normal pressure.

    The first principle pseudopotential calculations based on the Perdew-Burke-Ernzerhof (PBE) form of generalized gradient approximation (GGA) within density functional theory (DFT) has been utilized to investigate the stabilities of insoluble discharge products of oxygen and sulphur in the Na-O and Na-S batteries. Their structural, mechanical and electronic properties were determined. The lattice parameters were well reproduced and agree with the available experimental data. The heats of formation predict that all structures are generally stable and Na2S has the lowest value. The elastic constants suggest that all the structures are mechanically stable which in good agreement with the calculated phonon dispersions.

    2001-01-01

    Over the past 5 years, a new subgenre of horror films, referred to as plague films, has turned our focus to the threat of a hemorrhagic viral pandemic, comparable to the Spanish Flu epidemic of 1916. Based on the Ebola viral outbreaks of 1976, various writers have presented their accounts under the guise of increasing interest and prevention strategies. Disregarding inappropriate health care practices as the cause of these epidemics, accountability is refocused onto the rhetorically constructed, predatory nature of the virus. By employing Burke's theory of dramatism and pentadic analysis, the author examines this rhetorical construction of Ebola as a predatorial virus and its implications for public perceptions of public health endeavors.

    An alpha-glucosidase inhibitor, SKG-3, was isolated from the fruiting bodies of Ganoderma lucidum and its physico-chemical properties were characterized. It was a highly specific and effective reversible inhibitor of alpha-glucosidase. It showed very potent inhibitory activity against alpha-glucosidase with an IC50 value of 4.6 micro g/ml, but no activity for any other glycosidases tested. Enzyme activity could be recovered upon dialysis, thus providing evidence for the reversibility of the inhibition. A Lineweaver-Burk plot indicated that the SKG-3 inhibition of alpha-glucosidase was competitive.

    Dystonia is a complex movement disorder that is challenging to identify and quantify. The aim of this article is to review the clinical scales, kinematic measures, and functional implications of dystonia. Clinical measures include the Barry-Albright Dystonia Scale, the Burke-Fahn-Marsden Movement Scale, the Unified Dystonia Rating Scale, the Global Dystonia Rating Scale, and the Movement Disorder-Childhood Rating Scale. The evidence, reliability, and validity of each scale will be outlined. The Hypertonia Assessment Tool will be discussed emphasizing the importance of discriminating hypertonia. The role of kinematic measures in analyzing dystonia will be explored, as well as the potential for its future clinical applications.

  20. Importance of complex orbitals in calculating the self-interaction-corrected ground state of atoms

    2011-11-15

    The ground state of atoms from H to Ar was calculated using a self-interaction correction to local- and gradient-dependent density functionals. The correction can significantly improve the total energy and makes the orbital energies consistent with ionization energies. However, when the calculation is restricted to real orbitals, application of the self-interaction correction can give significantly higher total energy and worse results, as illustrated by the case of the Perdew-Burke-Ernzerhof gradient-dependent functional. This illustrates the importance of using complex orbitals for systems described by orbital-density-dependent energy functionals.

    Kinetic analysis of the interaction of malathion with camel erythrocyte acetylcholinesterase was investigated in the present study. The Michaelis-Menten constant (K(m)) for the hydrolysis of acetylthiocholine iodide (ASCh) was found to be 53.15 microM and the Vmax was 0.287 mumol/min/mg protein. The Kmapp and Vmaxapp were both decreased by increased malathion concentration. Dixon as well as Lineweaver-Burk plots and their secondary replots indicated that the nature of the inhibition was of the pure uncompetitive type with Ki value estimated as 102.1 ppm. The Kiapp decreased while Vmaxiapp increased by an increased concentration in ASCh.

    Theoretical studies on rutile type Palladium Dioxide were carried out with the aim of analyzing structural and electronic properties at ambient condition using the first principle calculation based on density functional theory. Within the framework of density functional theory, we used full potential linearized augmented plane wave method(FP-LAPW) in Wien 2k code. The exchange and correlation effect is treated with generalized gradient approximation (GGA) using the Perdew, Burke and Eruzeroff form. The charge density plots, density of states and band structure are plotted and discussed.

    In this paper, we have studied the structural and electronic properties of ScN and ScAs in zincblende (ZB) and rocksalt (RS) phases. We have employed the full potential linearized augmented plane wave (FP-APW) method within the density functional theory (DFT). Generalized gradient approximation (GGA), due to Perdew-Burke-Ernzerhof (PBE) has been used to estimate the exchange-correlation functional. Our band structure results for ScN shows the metallic nature, whereas ScAs shows the semiconducting behavior. The obtained results are in excellent agreement with earlier reported data.

    Density functional theory calculation was conducted to determine the optoelectronic properties of bismuth titanate sillenite (Bi12TiO20) and perovskite-like (Bi4Ti3O12) structures. The lattice parameters were experimentally obtained from Rietveld analysis. The density functional perturbation theory approach was used with the standard Perdew-Burke-Ernzerhof functional and screened Coulomb hybrid Heyd-Scuseria-Ernzerhof functional to investigate the electronic structure and absorption coefficient. Both compounds have good carrier transport properties, low effective hole and electron masses, high dielectric constant, and low exciton binding energy.

    2015-08-01

    The present brief report examined whether number of deployments, relationship satisfaction, and the interaction between number of deployments and relationship satisfaction predicted Navy members' reports of perpetrating physical partner violence. Participants were 80 U.S. Navy members assigned to an Arleigh Burke-class destroyer anticipating an 8-month deployment after Operation Enduring Freedom/Operation Iraqi Freedom. The effect that the number of deployments had on perpetrating physical partner violence diminished as relationship satisfaction increased. Results suggest the importance of designing domestic violence intervention and treatment efforts toward those who report high levels of deployment and low relationship satisfaction.

    2013-01-15

    A bioassay-guided fractionation of an ethanol extract of Buthus martensi Karsch led to the isolation of a potent α-glucosidase inhibitor (compound S). The structure was elucidated as a novel β-carboline glucoalkaloid, harmanyl β-d-glucopyranoside, on the basis of spectral data, including (1)H NMR, (13)C NMR, (1)H-(1)H COSY, NOESY, and HMBC. Compound S showed potent inhibitory activity against α-glucosidase, with an IC(50) value of 24 μM. A Lineweaver-Burk plot indicated that its inhibition of α-glucosidase was uncompetitive, with a Ki value of 16.1 μM.

    The (1)H and (13)C NMR chemical shifts of spiro-cycloalkylidene[60]fullerenes were assigned using experimental NMR data and the Density Functional Theory (DFT)-Gauge Independence Of Atomic Orbitals method (GAIO) calculation method in the Perdew Burke Ernzerhof (PBE)/3z approach. The calculated values of the (13)C NMR chemical shifts adequately reproduce the experimental values at this quantum chemistry approach. Similar assignments will be helpful for (13)C NMR spectral analysis of homo- and methano[60]fullerene derivatives for structure elucidation and to determine the influence of fullerene frames on substituents and the influence of substituents on fullerene cores.

    Well-defined quality control (QC) processes are used to determine whether a certain procedure or action conforms to a widely accepted standard and/or set of guidelines, and are important components of any laboratory quality assurance program (Popa-Burke et al., J Biomol Screen 14: 1017-1030, 2009). In this chapter, we describe QC procedures useful for monitoring the accuracy and precision of laboratory instrumentation, most notably automated liquid dispensers. Two techniques, gravimetric QC and photometric QC, are highlighted in this chapter. When used together, these simple techniques provide a robust process for evaluating liquid handler accuracy and precision, and critically underpin high-quality research programs.

    Potassium-argon age determinations for 84 volcanic, intrusive, and hydrothermally altered rocks from the Port Moller, Stepovak Bay, and Simeonof Island quadrangles are reported here. Of these age determinations, 78 samples were analyzed as part of Alaska Mineral Resource Assessment Program (AMRAP) studies in the Port Moller, Stepovak Bay, and Simeonof Island quadrangles. Age deter- minations for 6 of the samples have been previously published (Burk, 1965; Kienle and Turner, 1976; Wilson and others, 1981). This report consists of a sample location map, analytical data (table 1), and rock descriptions (table 2).

    Density functional theory calculation was conducted to determine the optoelectronic properties of bismuth titanate sillenite (Bi12TiO20) and perovskite-like (Bi4Ti3O12) structures. The lattice parameters were experimentally obtained from Rietveld analysis. The density functional perturbation theory approach was used with the standard Perdew-Burke-Ernzerhof functional and screened Coulomb hybrid Heyd-Scuseria-Ernzerhof functional to investigate the electronic structure and absorption coefficient. Both compounds have good carrier transport properties, low effective hole and electron masses, high dielectric constant, and low exciton binding energy.

    This review updates understanding and research on blepharospasm, a subtype of focal dystonia. Topics covered include clinical aspects, pathology, pathophysiology, animal models, dry eye, photophobia, epidemiology, genetics, and treatment. Blepharospasm should be differentiated from apraxia of eyelid opening. New insights into pathology and pathophysiology are derived from different types of imaging, including magnetic resonance studies. Physiologic studies indicate increased plasticity and trigeminal sensitization. While botulinum neurotoxin injections are the mainstay of therapy, other therapies are on the horizon.

    It is more than 50 years since Wilson (1963) suggested that a fixed plume of deep origin from the convecting mantle is generating the Hotspots of the Hawaiian chain on the overlying moving rigid lithosphere and nearly 45 years since Morgan (1972) followed by suggesting that the plumes which generate Hotspots rise only from the Core/Mantle Boundary (CMB). During the past ~ 15 years testing has begun of a refinement of Morgan's idea based on the observation that Plumes responsible for Hotspots, Large Igneous Provinces (LIPs) and a significant fraction of other igneous rocks (including kimberlites) originate only in Plume Generation Zones (PGZs) at the edges on the CMB of one or other of TUZO and JASON the 2 antipodal, equatorial, Large Low Shear Wave Velocity Provinces (LLSVPs) of the deep mantle (Garnero et al. 2007) or from similar PGZs at the edges on the CMB of ~8 smaller Low Shear Wave Velocity Provinces. Today I will: (i) demonstrate using dated Hotspot, Large Igneous Province and Kimberlite occurrence history and paleomagnetic rotations (e.g. Torsvik et al. 2010, Burke et al.2008) the stability throughout the past 0.55 Ga of the LLSVPs and LSVPs (ii) show from the history of the Earth and Mars how the LLSVPs and LSVPs are likely to have formed early in Earth history and to have been stable since ~ 4.4 Ga (Burke et al. 2012) (iii) show, following an analogy suggested by Jack Whitehead of similarity to atmospheric fronts, why plumes are generated only from PGZs on the CMB at the margins of LLSVPs and LSVPs. (iv) show from results of recent seismological studies of Iceland, Jan Mayen, Hawaii, Yellowstone, the Afar and Ontong Java, that although plumes rise vertically in the deep mantle from the CMB their fate in the top ~ 1, 000 km of the mantle is proving to be varied and to depend largely, as Wilson suggested, on how they interact with the plates above them. Properties of the Plume Generation Zones (PGZs) on the CMB and of the plumes that rise from them are

    A study has been made to test the hypothesis that general anesthetics such as urethane are able to inhibit light from a firefly reaction mixture. Urethane was found to reduce light emission in a dose-dependent manner, the minimal effective concentration being about 20 mM. Dixon plots gave a Ki value in the range of 175 to 215 mM. Lineweaver-Burk plots showed that urethane increases the apparent Km for ATP and reduces V{sub max} for the reaction. This is taken to mean that urethane acts as both a competitive and noncompetitive inhibitor of the firefly light reaction (mixed-type inhibition).

    A dimeric acylphenol and a potent α-glucosidase inhibitor, giganteone D (IC50 5.05μM), was isolated and characterized from the bark of Myristica cinnamomea King. The bark also yielded an acylphenol with an unprecedented skeleton for which the name cinnamomeone A (IC50 358.80μM) was proposed. Their structures were established by means of NMR and MS spectrometric analyses. The Lineweaver-Burk plot of giganteone D indicated that it was a mixed-type inhibitor. This is the first report on the α-glucosidase inhibiting potential of acylphenols.

    Electron-positron pair creation by multiphoton absorption in the collision of a relativistic electron with a strong laser beam is calculated within laser-dressed quantum electrodynamics. Total production rates, positron spectra, and relative contributions of different reaction channels are obtained in various interaction regimes. We study the process in a manifestly nonperturbative domain which is shown accessible to future experiments utilizing the electron beam lines at novel x-ray laser facilities or all-optical setups based on laser acceleration. Our theory moreover allows us to add further insights into the experimental data from SLAC [D. Burke, Phys. Rev. Lett. 79, 1626 (1997).].

    The gray fox (Urocyon cinereoargenteus) is a petite member of the family Canidae in the order Carnivora with a long muzzle and pointed ears (Samuel and Nelson 1982). The coat of the gray fox is silver gray across the back with significant amounts of rufus along the sides. This characteristic is often confused by people who see the flash of red and assume that the fox is a red fox (Vulpes vulpes). The gray fox has a black tipped tail with a dorsal black stripe that differentiates this species from the kit fox (Vulpes macrotis). The red fox has a white tipped tail. The gray fox weighs between 3-5 kg, occasionally to 7 kg. TL 800-1125, T 275-443, HF 100-150. (Jameson and Peeters 1988).

  8. Psychoanalytic theory in times of terror.

    PubMed

    Connolly, Angela

    2003-09-01

    Recent events have underlined in the most tragic and dramatic way the need for depth psychology to turn its attention to the psychology of terror. The present paper attempts to distinguish between the psychological modes of horror and terror and explores the different theoretical approaches of Burke, Freud, Kristeva and Jung to this problem in order to cast light on the individual and collective functions that horror and terror play. While all these authors stress that terror and horror play a role in structuring the sense of identity and in strengthening community bonds, Freud and Kristeva believe that the experience of horror works to increase the exclusion of otherness through mechanisms of repression or foreclosure while Burke and Jung see in the encounter with the Negative Sublime or with the Shadow the possibility of widening the boundaries of ego consciousness and of integration of 'otherness'. The paper then uses the analysis of two horror movies and of a particular socio-cultural context to illustrate these different functions of horror and terror and to delineate possible solutions to the problems facing society.

    This study was designed to evaluate the impact of the National Blueprint (NB) on the policies, programs, and organizational culture of selected national organizations. The theoretical model selected to assess the impact of the NB on organizational behavior was Burke's system theory of organizational change. Three organizations, AARP, the American College of Sports Medicine (ACSM), and the Administration on Aging (AoA), were selected for the study. Two individuals in each of these organizations were selected for interview. Semistructured interviews and document reviews were used in the data-collection process. Findings showed that the publication and establishment of the NB resulted in changes in the operating procedures of AARP, ACSM, and AoA. The results were broadly consistent with Burke's system theory of organizational change. The publication of the NB was shown to affect the behavior of organizational leaders, organizational culture, policies, programs, and individual and organizational performance. The new information generated has increased our understanding of the impact of health campaigns on organizational behavior.

  10. Microbial water quality and influences of fecal accumulation from a dog exercise area.

    The risk of water contamination by fecal bacteria may be increased if a watershed includes areas where feces accumulate as a result of specific land uses, such as areas where owners frequently exercise dogs. This study examined the effects of a year-round dog exercise area in the Burke Creek Recreational Area (BCRA) in the arid alpine environment of Stateline, Nevada. Burke Creek drains a small, high relief watershed, flows through a sedimentation basin in the BCRA, and enters Lake Tahoe. Over the course of 14 months, we analyzed water samples from the creek for Escherichia coli and collected feces from plots to estimate fecal accumulation. We found that accumulation was highly localized within the study area, amounting to approximately 100.1 lbs (45.5 kg) of dry matter in 14 months. Statistical analysis indicated, however, that fecal bacteria in water decreased as the stream flowed through the area, presumably due to effects of the sedimentation basin, wetlands, and die-off of E. coli in feces from exposure to environmental stresses. These results are useful for managing heavily used sites and understanding the effects of this type of land use on water quality.

    Background Assessing the quality of included trials is a central part of a systematic review. Many check-list type of instruments for doing this exist. Using a trial of antibiotic treatment for acute otitis media, Burke et al., BMJ, 1991, as the case study, this paper illustrates some limitations of the check-list approach to trial quality assessment. Results The general verdict from the check list type evaluations in nine relevant systematic reviews was that Burke et al. (1991) is a good quality trial. All relevant meta-analyses extensively used its data to formulate therapeutic evidence. My comprehensive evaluation, on the other hand, brought to the surface a series of serious problems in the design, conduct, analysis and report of this trial that were missed by the earlier evaluations. Conclusion A check-list or instrument based approach, if used as a short-cut, may at times rate deeply flawed trials as good quality trials. Check lists are crucial but they need to be augmented with an in-depth review, and where possible, a scrutiny of the protocol, trial records, and original data. The extent and severity of the problems I uncovered for this particular trial warrant an independent audit before it is included in a systematic review. PMID:19128475

    We report on measurements of plasma flows in temperature filaments of radial size less than the electron skin depth. The temperature filaments are created by injecting a small electron beam at low voltages into a large magnetized plasma column in the LAPD plasma device at UCLA. The flows are measured using a small double sided Langmuir probe (or Mach probe). Three cases are investigated. The first case is a study of plasma flow under conditions of classical heat transport (A.T. Burke, J.E. Maggs, and G.J. Morales, Phys. Plasmas 7, 544 (2000)) (i.e., transport due to Coulomb collisions) and the transition to non-classical conditions (A.T. Burke, J.E. Maggs, and G.J. Morales, Phys. Plasmas 7, 1397 (2000)) in a temperature filament created in the afterglow plasma. The second case is a beam injected during the discharge plasma at voltages comparable to the plasma discharge voltage. In this case radially outward propagating temperature fluctuations are observed to emanate from the beam heated region. The third case is a beam injected in the edge region of the plasma during the discharge. Reductions in the axial transport of heat are observed apparently due to the large pre-existing fluctuations that naturally occur at the plasma edge.

    Findings and recommendations are presented of a review of five case studies of ways to conserve energy through development planning and site design in communities. Two approaches were used. In the first approach, a conventional, pre-existing plan was analyzed to determine potential energy use. Once energy-conservation options were identified and evaluated, the conventional plan was modified by employing those options. This approach was used in The Woodlands, Burke Center, and Radisson studies. In the second approach, energy-conservation options are independently identified and evaluated. Those options that passed specific criteria screening were then utilized in developing one or more totally new plans based on energy objectives. This approach was used in Greenbrier and Shenandoah. Radisson is a new town on the outskirts of Syracuse, New York. Greenbrier is a 3000 acre planned community adjacent to Norfolk and Virginia Beach. Shenandoah is a proposed new town in the Atlanta urbanized area. The Woodlands is a new community under development north of Houston. Burke Center is a residential planned unit development in Fairfax County, Virgnia. (MCW)

    The kinetic parameters of W. aegyptia venom acetylcholinesterase (AChE) inhibition by procaine and tetracaine hydrochloride were investigated in the present study. Procaine and tetracaine reversibly inhibited the AChE activity in a concentration-dependent manner, the IC50 being about 0.28 and 0.04 mM, respectively. The Michaelis-Menten constant (K(m)) for the hydrolysis of acetylthiocholine iodide was found to be 0.051 mM with Vmax 10.2 mumole/min/mg protein. Both K(m) and Vmax were affected by procaine while only Vmax decreased with tetracaine. A Lineweaver-Burk plot and its secondary replot indicated that the nature of the inhibition is of the linear mixed type for procaine which is considered to be a mixture of competitive and noncompetitive types while the inhibition was noncompetitive for tetracaine. The values of Ki(slope) and K(intercept were estimated as 0.133 mM and 0.451 mM for procaine and 7.2 x 10(-3) mM for tetracaine, respectively, by the secondary replots of the Lineweaver-Burk plot.

    Despite many recent advances in rights for sexual and gender minorities in the United States, bias against lesbian, gay, bisexual, and transgender (LGBT) people still exists. In this Commentary, the author briefly reviews disparities with regard to LGBT health, in both health care and medical education, and discusses the implications of Burke and colleagues’ study of implicit and explicit biases against lesbian and gay people among heterosexual first-year medical students, published in this issue of Academic Medicine. Emphasis is placed on the ways in which physicians’ implicit bias against LGBT people can create a cycle that perpetuates a professional climate reinforcing the bias. The hidden curriculum in academic health centers is discussed as both a cause of this cycle and as a starting point for a research and intervention agenda. The findings from Burke and colleagues’ study, as well as other evidence, support raising awareness of LGBT discrimination, increasing exposure to LGBT individuals as colleagues and role models in academic health centers, and modifying medical education curricula as methods to break the cycle of implicit bias in medicine.

    This manuscript is written in response to Lydia Burke and Jesse Bazzul's article Locating a space of criticality as new scholars in science education. As doctoral students finding our place in the culture of science education, we respond by discussing our journeys towards the development of a scholarly identity, with particular focus on whether or how we see ourselves as critical scholars. Since each of us authoring this paper has a different perspective, a metalogue format is utilized to ensure all of our voices and journeys are represented. We use the Burke and Bazzul article as a platform for conversations about challenges faced for emerging scholars in the field of science education and explore how we see our role in responding to these challenges. Specifically, we discuss the barriers to publication, dissemination of research to practitioners, and how to approach these problems from a grounding in critical theory. As a result of our conversations, we conclude that there is a need to reshape the field of science education to invite more unorthodox research perspectives, methodologies, and publication formats. To do so, the issues we explore require a continued conversation between emerging scholars, practicing researchers, and practicing educators.

    Danshen is one of the most famous herbs in the world, and more and more danshen-prescribed drugs interactions have been reported in recent years. Evaluation of inhibition potential of danshen's major ingredients towards UDP-glucuronosyltransferases (UGTs) will be helpful for understanding detailed mechanisms for danshen-drugs interaction. Therefore, the aim of the present study is to investigate the inhibitory situation of cryptotanshinone and dihydrotanshinone I towards UGT enzyme-catalyzed propofol glucuronidation. In vitro the human liver microsome (HLM) incubation system was used, and the results showed that cryptotanshinone and dihydrotanshinone I exhibited dose-dependent inhibition towards HLM-catalyzed propofol glucuronidation. Dixon plot and Lineweaver-Burk plot showed that the inhibition type was best fit to competitive inhibition type for both cryptotanshinone and dihydrotanshinone I. The second plot using the slopes from the Lineweaver-Burk plot versus the concentrations of cryptotanshinone or dihydrotanshinone I was employed to calculate the inhibition parameters (Ki) to be 0.4 and 1.7μM, respectively. Using the reported maximum plasma concentration (Cmax), the altered in vivo exposure of propofol increased by 10% and 8.2% for the co-administration of dihydrotanshinone I and cryptotanshinone, respectively. All these results indicated the possible danshen-propofol interaction due to the inhibition of dihydrotanshinone I and cryptotanshinone towards the glucuronidation reaction of propofol.

    The aim of the present study was to investigate the influence of biotransformation of baicalin into baicalein towards the inhibition potential towards one of the most important drug-metabolizing enzymes (DMEs) UDP-glucuronosyltransferases (UGTs). in vitro incubation method using recombinant UGTs-catalyzed 4-methylumbelliferone (4-MU) glucuronidation was used to evaluate the inhibition towards important UGT isoforms in the liver, including UGT1A1, 1A3, 1A6, 1A9, and 2B7. At the same concentration (100 microM), baicalein showed stronger inhibition potential than baicalin towards all the tested UGT isoforms. Data fitting using Dixon plot and Lineweaver-Burk plot was carried out to determine the inhibition type, and the second plot with the slopes from Lineweaver-Burk plot towards baicalein's concentrations was used to calculate the inhibition kinetic parameters (K(i)). Competitive inhibition type was observed for UGT1A1, 1A6, 1A9 and 2B7, and noncompetitive inhibition was detected for UGT1A3. The inhibition kinetic parameters (K(i)) were calculated to be 1.2, 5.1, 15.3, 26.3, and 48.9 microM for UGT1A1, 1A3, 1A6, 1A9, and 2B7, respectively. All these information reminds us of the necessary monitoring when oral administration of baicalin or baicalin-containing herbs.

    Polyphenols present in foods and supplements may contribute to human health by preventing cardiovascular diseases and cancer. Drug-food or drug-herb interactions have recently come into focus but, except for some phytochemicals, few components of food or herbs participate in such interactions. In this study, we systematically evaluated the inhibitory effects of 60 polyphenols and related compounds on human cytochrome P450 (CYP) 3A4 and CYP2C9 activity by in vitro assay to investigate whether some polyphenols induce drug interactions. In addition, the kinetics of potent CYP inhibitors was investigated by Lineweaver-Burk plot analysis. Three coumarins and 12 flavonoids significantly suppressed CYP3A4 or CYP2C9 activities. Lineweaver-Burk plot analysis indicated that apigenin and its dimer amentoflavone and imperatorin displayed a mixed type of inhibition on CYP3A4 or CYP2C9. Among the inhibitors, amentoflavone was the most potent inhibitor of CYP3A4 and CYP2C9 activities with IC(50) values of 0.07 and 0.03 microM, respectively. The K(i) value of amentoflavone was significantly lower than that of the CYP2C9 inhibition positive control sulfaphenazole. These findings suggest that some dietary polyphenols may have the potential to inhibit the metabolism of clinical drugs.

    The aim of the present study is to evaluate the inhibitory effects of liver UDP-glucuronosyltransferases (UGTs) by glycyrrhizic acid and glycyrrhetinic acid, which are the bioactive ingredients isolated from licorice. The results showed that glycyrrhetinic acid exhibited stronger inhibition towards all the tested UGT isoforms, indicating that the deglycosylation process played an important role in the inhibitory potential towards UGT isoforms. Furthermore, the inhibition kinetic type and parameters were determined for the inhibition of glycyrrhetinic acid towards UGT1A3 and UGT2B7. Data fitting using Dixon and Lineweaver-Burk plots demonstrated that the inhibition of UGT1A3 and UGT2B7 by glycyrrhetinic acid was best fit to competitive and noncompetitive type, respectively. The second plot using the slopes from Lineweaver-Burk plots versus glycyrrhetinic acid concentrations was employed to calculate the inhibition kinetic parameters (K(i)), and the values were calculated to be 0.2 and 1.7 μM for UGT1A3 and UGT2B7, respectively. All these results remind us the possibility of UGT inhibition-based herb-drug interaction. However, the explanation of these in vitro parameters should be paid more caution due to complicated factors, including the probe substrate-dependent UGT inhibition behaviour, environmental factors affecting the abundance of herbs' ingredients, and individual difference of pharmacokinetic factors.

    As a multifunctional group of enzymes, glutathione S-transferases (GSTs) are capable of inactivation, degradation or excretion of wide range of compounds catalytically or non-catalytically. However, to date, no study has been addresses the presence of GSTs in archaea based on their enzymatic functions. In this study, beside glutathione (GSH) amount measurement, the determination of GST activity in halophilic archaeon called Haloarcula hispanica ATCC 33960 were aimed. According to the results, specific activity was determined as 19.68 nmol min⁻¹ mg⁻¹ protein and GSH content were found to be as 194 μg g⁻¹ K(m) and V(max) values for CDNB and GSH calculated from Lineweaver-Burk plot were 0.46 mM and 27.93 nmol min⁻¹ mg⁻¹, 0.13 mM and 22.03 nmol min⁻¹ mg⁻¹, respectively. Hanes-Woolf and Eadie-Hofstee plots for CDNB and GSH were also found to be in co-relation with the results obtained from Lineweaver-Burk plot. To the best of our knowledge, GST enzymes have not been identified in archaea yet, at least based on their catalytic activities. Therefore, it is the first report on this area.

    In this study, the carbonic anhydrase (CA) enzyme was purified from Black Sea trout (Salmo trutta Labrax Coruhensis) kidney with a specific activity of 603.77EU/mg and a yield of 35.5% using Sepharose-4B-l-tyrosine- sulphanilamide affinity column chromatography. For determining the enzyme purity and subunit molecular mass, sodiumdodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) was performed and single band was observed. The molecular mass of subunit was found approximately 29.71kDa. The optimum temperature, activation energy (Ea), activation enthalpy (ΔH) and Q10 values were obtained from Arrhenius plot. Km and Vmax values for p-nitrophenyl acetate of the purified enzyme were calculated from Lineweaver-Burk graphs. In addition, the inhibitory effects of different heavy metal ions (Fe(2+), Pb(2+), Co(2+), Ag(+) and Cu(2+)) on Black Sea trout kidney tissue CA enzyme activities were investigated by using esterase method under in vitro conditions. The heavy metal concentrations inhibiting 50% of enzyme activity (IC50) were obtained. Finally Ki values and inhibition types were calculated from Lineweaver-Burk graphs.

    Abstract Two of three species previously classified in Calosota Curtis (Hymenoptera: Eupelmidae) from the Neotropical region are transferred to Eupelminae. Calosota eneubulus (Walker) from Galapagos Islands is transferred to Eupelmus Dalman as Eupelmus (Eupelmus) eneubulus (Walker), comb. n., and Calosota silvai (Brèthes) from Chile is transferred to Brasema Cameron as Brasema silvai comb. n. Calosota cecidobius (Kieffer) from Argentina is retained in Calosota, with reservation, as an unrecognized species. The species of Calosota from the New World excluding South America are revised. Eleven species are recognized, including the seven newly described species Calosota albipalpus sp. n. (Costa Rica, Mexico, USA, Venezuela), Calosota bicolorata sp. n. (USA), Calosota elongata sp. n. (USA), Calosota longivena sp. n. (USA), Calosota panamaensis sp. n. (Panama), Calosota setosa sp. n. (Bahamas, Dominican Republic, USA), and Calosota speculifrons sp. n. (Costa Rica, USA). The 11 regional species and the Palaearctic species Calosota vernalis Curtis are keyed and illustrated. Calosota vernalis is not known to occur in the New World but is included in the key and diagnosed because it has been intercepted in quarantine in Canada. Calosota pseudotsugae Burks is placed in synonymy under Calosota acron (Walker), syn. n.,and Calosota kentra Burks, Calosota montana Burks and Calosota septentrionalis Hedqvist are placed in synonymy under Calosota aestivalis Curtis syn. n. Calosota modesta Bolívar y Pieltain is removed from synonymy under Calosota viridis Masi, stat. rev., and Calosota viridis, Calosota matritensis Bolívar y Pieltain, and Calosota coerulea Nikol’skaya are placed in synonymy under Calosota metallica (Gahan), syn. n. Calosota grylli Erdös is confirmed as a separate species from Calosota metallica based on features of both sexes. It is suggested that Calosota ariasi Bolívar y Pieltain may be a synonym of Calosota aestivalis, Calosota bolivari Askew may be a

    Ambient OH and HO2 concentrations were measured by laser induced fluorescence (LIF) during the PRIDE-PRD2006 (Program of Regional Integrated Experiments of Air Quality over the Pearl River Delta, 2006) campaign at a rural site downwind of the megacity of Guangzhou in Southern China. The observed OH concentrations reached daily peak values of (15-26) × 106 cm-3 which are among the highest values so far reported for urban and suburban areas. The observed OH shows a consistent high correlation with j(O1D) over a broad range of NOx conditions. The correlation cannot be reproduced by model simulations, indicating that OH stabilizing processes are missing in current models. The observed OH exhibited a weak dependence on NOx in contrast to model predictions. While modelled and measured OH agree well at NO mixing ratios above 1 ppb, a continuously increasing underprediction of the observed OH is found towards lower NO concentrations, reaching a factor of 8 at 0.02 ppb NO. A dependence of the modelled-to-measured OH ratio on isoprene cannot be concluded from the PRD data. However, the magnitude of the ratio fits into the isoprene dependent trend that was reported from other campaigns in forested regions. Hofzumahaus et al. (2009) proposed an unknown OH recycling process without NO, in order to explain the high OH levels at PRD in the presence of high VOC reactivity and low NO. Taking a recently discovered interference in the LIF measurement of HO2 into account, the need for an additional HO2 → OH recycling process persists, but the required source strength may be up to 20% larger than previously determined. Recently postulated isoprene mechanisms by Lelieveld et al. (2008) and Peeters and Müller (2010) lead to significant enhancements of OH expected for PRD, but an underprediction of the observed OH by a factor of two remains at low NO (0.1-0.2 ppb). If the photolysis of hydroperoxy aldehydes from isoprene is as efficient as proposed by Peeters and Müller (2010), the

    This study broadens the archaeological research of the the Bezděz - Doksy region in Northern Bohemia, Czech Republic (Dreslerová et al., 2013). Extensive field works between 2008 and 2012 showed that the region has been settled since the La Tène period. Survey of the alluvial plain of the Robečský stream revealed a record of two intensive erosion episodes in the catchment. We suppose that the first episode may be connected to land use changes and the beginnings of agriculture at the site in the La Tène period. The second episode may be connected to the foundation of the medieval village of Okna, which came into existence in the vicinity of the La Tène settlement. The accelerated erosion of former albeluvisols (on loess) led to significant changes of landscape in the region. The aim of this contribution is to bring a reconstruction of soils, vegetation and relief at the site of Okna before the human occupancy and to detect landscape changes over the time. It focuses on the hypothesis that the accelerated soil erosion has been occurring at the site since the first anthropogenic influence like it is demonstrated by other studies in Europe (e.g. Leopold and Völkel, 2007; Boardman, 2013). An abrupt change of land use from forest to arable land is proved by palynological records. Simultaneously there are buried soil horizons and alluvial sediments which can be studied as geoarchives. The difficulties in reconstruction of relief and quantification of the historical erosion effects are faced by applying GIS and model approaches (Peeters et al., 2003). References Boardman, J., 2013.

  7. Infrared spectra of interstellar deuteronated PAHs

    Polycyclic Aromatic Hydrocarbon (PAH) molecules have emerged as a potential constituent of the ISM that emit strong features at 3.3, 6.2, 7.7, 8.6, 11.2 and 12.7 μm with weaker and blended features in the 3-20μm region. These features are proposed to arise from the vibrational relaxation of PAH molecules on absorption of background UV photons (Tielens 2008). These IR features have been observed towards almost all types of astronomical objects; say H II regions, photodissociation regions, reflection nebulae, planetary nebulae, young star forming regions, external galaxies, etc. A recent observation has proposed that interstellar PAHs are major reservoir for interstellar deuterium (D) (Peeters et al. 2004). According to the `deuterium depletion model' as suggested by Draine (2006), some of the Ds formed in the big bang are depleted in PAHs, which can account for the present value of D/H in the ISM. Hence, study of deuterated PAHs (PADs) is essential in order to measure D/H in the ISM.In this work, we consider another probable category of the large PAH family, i.e. Deuteronated PAHs (DPAH+). Onaka et al. have proposed a D/H ratio which is an order of magnitude smaller than the proposed value of D/H by Draine suggesting that if Ds are depleted in PAHs, they might be accommodated in large PAHs (Onaka et al. 2014). This work reports a `Density Functional Theory' calculation of large deuteronated PAHs (coronene, ovalene, circumcoronene and circumcircumcoronene) to determine the expected region of emission features and to find a D/H ratio that is comparable to the observational results. We present a detailed analysis of the IR spectra of these molecules and discuss the possible astrophysical implications.ReferencesDraine B. T. 2006, in ASP Conf. Ser. 348, Proc.

    The influence of high concentrations of ferric ions on the biochemical activity of Acidithiobacillus ferrooxidans was studied using intact cells. The specific oxidation rate of ferrous ions decreased with increasing ferric ion concentration. Lineweaver-Burk plots revealed typical competitive inhibition kinetics, because the slopes varied with the ferric ion concentration. A linear relationship between the slope and the square of the ferric ion concentration revealed that the iron-oxidizing enzyme system of A. ferrooxidans was competitively inhibited by about two molecules of ferric ion. The kinetic equation based on this inhibition model agreed with the experimental observation at a high ferric ion concentration where the bacterium is usually exposed in bioleaching and biooxidation plants.

    The Mississippi Embayment regional seismic hazard (Fuller, 1912; Nuttli, 1973, 1982, 1983), associated with the New Madrid seismic zone (NMSZ) is attributed to displacement on seismogenic structures primarily within the failed Reelfoot rift (Burke and Dewey, 1973; Ervin and McGinnis, 1975; Hildenbrand, 1977; Johnston and Shedlock, 1992). Hildenbrand and others (1977) and Hildenbrand (1985) used potential field data to show the northeast trend of the buried rift and the existence of related intrusive bodies. The Mississippi Valley graben (Hildenbrand and others, 1977; Kane and others, 1981; Hildenbrand, 1985; Wheeler and others, 1993), also referred to as the Reelfoot graben (Hildenbrand and Hendricks, 1995), is here considered to be the structural expression of the Reelfoot rift at the Precambrian basement surface.

    We studied the possible catalytic effect that a transition metal atom could have after being adsorbed in a surface of hexagonal boron nitride (hBN). We considered platinum and titanium, performing ab-initio calculations, including molecular dynamics at 300K, within the Density Functional Theory. We considered an hBN surface either with a vacancy of a Boron atom, or with a vacancy of a Nitrogen atom, and we found that both titanium and platinum are absorbed at the place of the vacancy for both cases considered. Afterwards, we found that this decoration of the hBN surface indeed has a catalytic effect on the adsorption of a carbon monoxide molecule. Possible desorption was explored, at 800 K. To perform the calculations, the Quantum ESPRESSO package code was used. The generalized gradient corrected Perdew-Burke-Ernzerhof (PBE) approximation was used for the exchange and correlation functional.

    Virtual reality is used in marketing research to shape food selection and purchase decisions. Could it be used to counteract the marketing of less-nutritious foods and teach healthier food selection? This article presents interviews with Raymond Burke, Ph.D., of Indiana University Bloomington, and Rachel Jones, M.P.H., of the University of Utah College of Health. Topics covered include new marketing research technologies, including virtual reality simulations; retailing and shopper behavior; and the use of virtual grocery stores to help students explore quality of diet and food/nutrient relationships. The interviewees discuss how the technologies they have developed fit into research and behavior change related to obesity and diabetes.

    Recently, Tao and Mo derived a meta-generalized gradient approximation functional based on a model exchange-correlation hole. In this work, the performance of this functional is assessed on standard test sets, using the 6-311++G(3df,3pd) basis set. These test sets include 223 G3/99 enthalpies of formation, 99 atomization energies, 76 barrier heights, 58 electron affinities, 8 proton affinities, 96 bond lengths, 82 harmonic vibrational frequencies, 10 hydrogen-bonded molecular complexes, and 22 atomic excitation energies. Our calculations show that the Tao-Mo functional can achieve high accuracy for most properties considered, relative to the local spin-density approximation, Perdew-Burke-Ernzerhof, and Tao-Perdew-Staroverov-Scuseria functionals. In particular, it yields the best accuracy for proton affinities, harmonic vibrational frequencies, hydrogen-bond dissociation energies and bond lengths, and atomic excitation energies.

    The electronic structure and formation energy of the Ga1-xCrxAs compound has been studied by principles of methods based on the Density Functional Theory. The formation energy of the compound is calculated, as well as the vacancies and substitutions. The equations of Kohn-Sham are solved employing the plane wave method and the ultra-soft atomic pseudopotentials approximation. The generalized gradient approximation was employed for the exchange and correlation energy in the Perdew-Burke-Ernzerhof (PBE) parametrization as it is implemented in the computational code Quantum Espresso. It was found that the most favourable configuration is the GaAs lattice by doing the substitution of one Ga atom by one Cr in the analyzed lattices.

    An enzymatic procedure based on a catalase biosensor for the detection of forchlorfenuron (CPPU) has been reported in this work. Catalase was immobilized on boron nitride (BN) sheets dispersed in chitosan by adsorption. The immobilized catalase exhibited direct electron transfer character and excellent electrocatalytic activity towards H2O2 reduction. After introducing CPPU into the H2O2 containing phosphate buffer solution, the catalase-catalyzed H2O2 reduction current decreased. By measuring the current decrease, CPPU can be determined in the range of 0.5-10.0 µM with the detection limit of 0.07 μM. The non-competitive inhibition behavior of CPPU towards catalase was verified by the Lineweaver-Burk plots. Long stability character has been ascribed to this biosensor. Possible use of this biosensor in flow systems is illustrated. The proposed biosensor has been successfully applied to CPPU determination in fruits samples with satisfactory results.

    Silkworm pupa (Bombyx mori) protein was hydrolyzed using gastrointestinal endopeptidases (pepsin, trypsin and α-chymotrypsin). Then, the hydrolysate was purified sequentially by ultrafiltration, gel filtration chromatography and RP-HPLC. A novel ACE inhibitory peptide, Ala-Ser-Leu, with the IC50 value of 102.15μM, was identified by IT-MS/MS. This is the first report of Ala-Ser-Leu from natural protein. Lineweaver-Burk plots suggest that the peptide is a competitive inhibitor against ACE. The molecular docking studies revealed that the ACE inhibition of Ala-Ser-Leu is mainly attributed to forming very strong hydrogen bonds with the S1 pocket (Ala354) and the S2 pocket (Gln281 and His353). The results indicate that silkworm pupa (B. mori) protein or its gastrointestinal protease hydrolysate could be used as a functional ingredient in auxiliary therapeutic foods against hypertension.

    A model is developed for the evaluation of acreages (proportions) of different crop-types over a geographical area using a classification approach and methods for estimating the crop acreages are given. In estimating the acreages of a specific croptype such as wheat, it is suggested to treat the problem as a two-crop problem: wheat vs. nonwheat, since this simplifies the estimation problem considerably. The error analysis and the sample size problem is investigated for the two-crop approach. Certain numerical results for sample sizes are given for a JSC-ERTS-1 data example on wheat identification performance in Hill County, Montana and Burke County, North Dakota. Lastly, for a large area crop acreages inventory a sampling scheme is suggested for acquiring sample data and the problem of crop acreage estimation and the error analysis is discussed.

    Using the van der Waals density functional with C09 exchange (vdW-DF-C09), which has been applied to describing a wide range of dispersion-bound systems, we explore the physical properties of prototypical ABO3 bulk ferroelectric oxides. Surprisingly, vdW-DF-C09 provides a superior description of experimental values for lattice constants, polarization and bulk moduli, exhibiting similar accuracy to the modified Perdew-Burke-Erzenhoff functional which was designed specifically for bulk solids (PBEsol). The relative performance of vdW-DF-C09 is strongly linked to the form of the exchange enhancement factor which, like PBEsol, tends to behave like the gradient expansion approximation for small reduced gradients. These results suggest the general-purpose nature of the class of vdW-DF functionals, with particular consequences for predicting material functionality across dense and sparse matter regimes.

    The nonlocal resonance model developed earlier for the description of low-energy inelastic and reactive electron-HCl collisions has been adapted to the electron-HBr collision system. The parameters of the model have been determined by fitting the eigenphase sum in the fixed-nuclei approximation to the data of an {ital ab} {ital initio} {ital R}-matrix calculation of Morgan, Burke, and collaborators. The Schwinger-Lanczos method has been employed to solve the nuclear scattering problem with a nonlocal, complex, and energy-dependent effective potential. Fully converged cross sections have been obtained on a dense grid of energies for many vibrational excitation, deexcitation, and dissociative channels in both HBr and DBr. The computed cross sections are generally in good agreement with experiment as far as data are available. {copyright} {ital 1996 The American Physical Society.}

    Childhood obesity remains a substantial health concern for our population and thoughtful attempts to develop and evaluate the utility of programs to reduce childhood obesity levels are needed. Unfortunately, we believe the conclusion by Burke et al. that the HealthMPowers program produces positive change in body composition is incorrect because the results obtained are likely due to regression to the mean (RTM), a well-known threat to the validity of studies that is often overlooked. Using empirical data, we demonstrate that RTM is likely to be the cause for the changes reported. A more reasonable conclusion than the one of effectiveness the authors offered would be that the results did not support the effectiveness of the intervention. Public health officials, parents, school leaders, community leaders, and regulators need and deserve valid evidence free from spin on which they can base decisions.

    The purpose of this work is to carry out direct numerical simulations of diffusion controlled combustion with non-unity Lewis numbers for the reactants and products, thus accounting for the differential diffusion effects of the temperature and concentration fields. We use a formulation based on combining the conservation equations in a way to eliminate the reaction terms similar to the method used by Burke and Schumann (1928) for unity Lewis numbers. We present calculations for an axisymmetric fuel jet and for a planar, time evolving mixing layer, leaving out the effects of thermal expansion and variations of the transport coefficients due to the heat release. Our results show that the front of the flame shifts toward the fuel or oxygen sides owing to the effect of the differential diffusion and that the location of maximum temperature may not coincide with the flame. The dependence of the distribution of the reaction products on their Lewis number has been investigated.

    Cyclic AMP, used as dibutyryl derivative for better permeability, has a relaxing effect on smooth muscle preparations from human uterine tissue (surgical material). The observed decrease of tonus and frequency depends on the concentration applied, shown in the range between 50 and 300 microM. cAMP looses its physiological activity by irradiation in vitro; in addition an inhibitory action of the irradiation products on uterine tissue could be proved. From the data of the Lineweaver-Burk plots, showing the competition between non-irradiated and irradiated cAMP, a ten-to twentyfold higher affinity of the irradiation products to the receptor compared to that of this transmitter could be calculated. The results show that preparations of human origin with beta-receptors behave similarly to animal tissues with beta-receptors. They are further discussed with respect to a better understanding of dose-response curves for chemical and physiological inactivation.

    The engineering study group in the LOUISA workshop was responsible for producing a preliminary general design for an optical synthetic aperture telescope on the Moon. This design is intended to be a test case for focusing continuing design studies. The scope of the design included consideration of the array geometry, individual telescopes, metrology, site attributes, and construction. However, no attempt was made to go into further depth in the design than to cover the essential characteristics of the instrument. The starting point for the array design was the lunar optical array discussed by Burke (1985). His array geometry followed the design and correlation procedure of the 27-element Very Large Array (VLA) radio telescopes near Socorro, New Mexico.

    Partition Density Functional Theory (PDFT) is a formally exact method for obtaining molecular properties from self-consistent calculations on isolated fragments [1,2]. For a given choice of fragmentation, PDFT outputs the (in principle exact) molecular energy and density, as well as fragment densities that sum to the correct molecular density. I describe our progress understanding the behavior of the fragment energies as a function of fragment occupations, derivative discontinuities, practical implementation, and applications of PDFT to small molecules. I also discuss implications for ground-state Density Functional Theory, such as the promise of PDFT to circumvent the delocalization error of approximate density functionals. [4pt] [1] M.H.

    The limits of Lyrcus Walker (1842), Catolaccus Thomson (1878), Eurydinoteloides Girault (1913a), Trimeromicrus Gahan (1914), and Jaliscoa Bouček (1993) are re-evaluated and redefined to better reflect observed distribution of morphological features. Nine of 13 New World species of Catolaccus are transferred to other genera and photographs of the primary type specimens are given to assist future recognition. New features are provided to assist identification of the remaining four Nearctic species of Catolaccus and these are compared to European species, with the observation that C. kansensis (Girault 1917c) could be a junior synonym of C. crassiceps (Masi 1911). Trimeromicrus is removed from synonymy under Lyrcus for the single species T. maculatus Gahan (1914) rev. comb. Newly synonymized under Lyrcus is the Australasian genus Neocylus Bouček (1988) n. syn. Ten species are newly transferred to Lyrcus-L. nigraeneus (Girault 1915) n. comb. (from Neocylus), L. helice (Walker 1843) n. comb. and L. cyaneus (Girault 1911) n. comb.

    We have studied structural, mechanical and dynamical properties of PdC and CdC compounds to predict the most stable structure. We have focused on seven binary structure types as rock salt (RS), caesium chloride (CsCl), zinc blende (ZB), wurtzite (WZ), tungsten carbide (WC), cadmium telluride (CdTe) and nickel arsenide (NiAs). For modelling exchange-correlation effects we have used generalized gradient (GGA) approximation based on Perdew-Burke-Ernzhorf functional (PBE). The polycrystalline elastic moduli such as Young's and shear moduli, Poisson's ratio, sound velocities, Debye temperatures and shear anisotropic factors have been presented for mechanically stable structures using second-order elastic constants calculated from the stress-strain relations. The results show that PdC is thermodynamically, mechanically and dynamically stable in ZB structure. On the other hand, while CdC is energetically in favor of RS structure, it is mechanically and dynamically stable in ZB structure.

    Small gold cluster anions Aun- are known for their unusual two-dimensional (2D) structures, giving rise to properties very different from those of bulk gold. Previous experiments and calculations disagree about the number of gold atoms nc where the transition to 3D structures occurs. We combine trapped ion electron diffraction and state of the art electronic structure calculations to resolve this puzzle and establish nc=12 . It is shown that theoretical studies using traditional generalized gradient functionals are heavily biased towards 2D structures. For a correct prediction of the 2D-3D crossover point it is crucial to use density functionals yielding accurate jellium surface energies, such as the Tao-Perdew-Staroverov-Scuseria (TPSS) functional or the Perdew-Burke-Ernzerhof functional modified for solids (PBEsol). Further, spin-orbit effects have to be included, and large, flexible basis sets employed. This combined theoretical-experimental approach is promising for larger gold and other metal clusters.

  7. Diagnostic Categories in Autobiographical Accounts of Illness.

    2015-01-01

    Working within frameworks drawn from the writings of Immanuel Kant, Alfred Schutz, and Kenneth Burke, this article examines the role that diagnostic categories play in autobiographical accounts of illness, with a special focus on chronic disease. Four lay diagnostic categories, each with different connections to formal medical diagnostic categories, serve as typifications to make sense of the way the lifeworld changes over the course of chronic illness. These diagnostic categories are used in conjunction with another set of typifications: lay epidemiologies, lay etiologies, lay prognostics, and lay therapeutics. Together these serve to construct and reconstruct the self at the center of the lifeworld. Embedded within the lay diagnostic categories are narratives of progression, regression, or stability, forms of typification derived from literary and storytelling genres. These narratives are developed by the self in autobiographical accounts of illness.

    Through doping boron nitride nanotubes, their band gaps could be controlled which results in extending the range of their applications particularly in nanosensors. In this article, the structural and elastic properties of Be and Mg doped boron nitride nanotubes with various chiralities are studied based on ab initio density functional calculations. In order to perform the density functional theory (DFT) calculations, the exchange correlation of Perdew-Burke-Ernzerhof within the generalized gradient approximation (GGA) framework is employed. It is observed that doping Be and Mg atoms increases the equilibrium strain energy of boron nitride nanotubes. Furthermore, it is found that among all of the considered nanotubes, an increase in the value of Young's modulus of (4, 4) armchair boron nitride nanotube through doping Be atom instead of boron atom is so considerable.

  9. Van der Waals density functional: An appropriate exchange functional

    2010-04-01

    In this Rapid Communication, an exchange functional which is compatible with the nonlocal Rutgers-Chalmers correlation functional [van der Waals density functional (vdW-DF)] is presented. This functional, when employed with vdW-DF, demonstrates remarkable improvements on intermolecular separation distances while further improving the accuracy of vdW-DF interaction energies. The key to the success of this three-parameter functional is its reduction in short-range exchange repulsion through matching to the gradient expansion approximation in the slowly varying/high-density limit while recovering the large reduced gradient, s , limit set in the revised Perdew-Burke-Ernzerhof (revPBE) exchange functional. This augmented exchange functional could be a solution to long-standing issues of vdW-DF lending to further applicability of density-functional theory to the study of relatively large, dispersion bound (van der Waals) complexes.

    Root of Panax notoginseng (Burk.) F.H. Chen (Sanqi in Chinese) is one of traditional Chinese medicines (TCMs) based functional food. Saponins are the major bioactive components. The shortage of reference compounds or chemical standards is one of the main bottlenecks for quality control of TCMs. A novel strategy, i.e. standardized reference extract based qualification and single calibrated components directly quantitative estimation of multiple analytes, was proposed to easily and effectively control the quality of natural functional foods such as Sanqi. The feasibility and credibility of this methodology were also assessed with a developed fast HPLC method. Five saponins, including ginsenoside Rg1, Re, Rb1, Rd and notoginsenoside R1 were rapidly separated using a conventional HPLC in 20 min. The quantification method was also compared with individual calibration curve method. The strategy is feasible and credible, which is easily and effectively adapted for improving the quality control of natural functional foods such as Sanqi.

    Nine furoquinoline alkaloids (1-9) were isolated from the leaves of Evodia lepta based on bioassay-guided fractionation and chromatographic techniques. All isolates were evaluated for their cholinesterase (ChEs) inhibitory activities, in which kokusaginine (7) and melineurine (5) exhibited the highest activity toward AChE and BChE, respectively. Lineweaver-Burk plots indicated that 5 and 7 were mixed mode inhibitors of both ChE enzymes. Molecular docking studies on the binding sites of AChE and BChE were performed in order to afford a molecular insight into the mode of action of these active compounds. From this study these compounds have emerged as promising molecules for Alzheimer's disease therapy.

    A novel series of terminal and internal phosphonate esters based on our previously developed aryl carboxylate-type tryptase selective inhibitor 1 was synthesized. The potency of these synthesized compounds was assessed in vitro with an enzyme inhibition assay using three available serine proteases, that is, tryptase, trypsin, and thrombin. The internal phosphonate derivative 6 showed potent thrombin inhibitory activity with an IC50 value of 1.0 μM, whereas it exhibited no or only weak tryptase and trypsin inhibition at 10 μM. The Lineweaver-Burk plot analysis indicates that the inhibition pattern of thrombin with 6 is non-competitive in spite of the fact that the lead carboxylate compound 1 is competitive inhibitor. Therefore, the skeletal conversion of the carboxylate into a phosphonate alters the mode of molecular recognition of these inhibitors by thrombin.

    A proteinase inhibitor was isolated and partially purified from the exocarp of eggplant, Solanum melongena L., by means of acetate buffer extraction, heat treatment, salting-out and column chromatography on DEAE-cellulose. This preparation showed inhibitory activities on various proteinases; trypsin [EC 3.4.4.4] and Pronase were strongly inhibited while alpha-chymotrypsin [EC 3.4.4.5] and Nagarse were weakly inhibited. The inhibitor was a protein substance, and, therefore, it was gradually inactivated by the long-time incubation with Pronase. The inhibition mode was non-competitive on trypsin and competitive on Pronase on the basis of Lineweaver-Burk plots. The investigations on the inhibition behavior in the co-existence of two kinds of proteinases suggested that the inhibitor was not of multi-headed type.

    The planar to three dimensional transition of Au13-nAgn clusters is investigated. To do so the low lying energy configurations for all possible concentrations (n values) are evaluated. Many thousands of possible conformations are examined. They are generated using the procedure developed by Rogan et al. in combination with the semi-empirical Gupta potential. A large fraction of these (the low lying energy ones) are minimized by means of Density Functional Theory (DFT) calculations. We employ the Tao, Perdew, Staroverov, and Scuseria (TPSS) meta-GGA functional and the Perdew, Burke and Ernzerhof (PBE) GGA functional, and compare their results. The effect of spin-orbit coupling is studied as well as the s-d hybridization. As usual in this context the results are functional-dependent. However, both functionals lead to agreement as far as trends are concerned, yielding just two relevant motifs, but their results differ quantitatively.

    Common approximate exchange-correlation functionals suffer from self-interaction error, and as a result, their corresponding potentials have incorrect asymptotic behavior. The exact asymptote can be imposed by introducing range separation into the exchange component and replacing the long-range portion of the approximate exchange by the Hartree-Fock counterpart. The authors show that this long-range correction works particularly well in combination with the short-range variant of the Perdew-Burke-Ernzerhof (PBE) exchange functional. This long-range-corrected hybrid, here denoted LC-{omega}PBE, is remarkably accurate for a broad range of molecular properties, such as thermochemistry, barrier heights of chemical reactions, bond lengths, and most notably, description of processes involving long-range charge transfer.

    The inhibitory effect and associated mechanisms of salicylic acid (SA) on the browning of fresh-cut Chinese chestnut were investigated. Shelled and sliced chestnuts were immersed in different concentrations of an SA solution, and the browning of the chestnut surface and interior were inhibited. The activities of polyphenol oxidase (PPO) and peroxidase (POD) extracted from chestnuts were measured in the presence and absence of SA. SA at concentrations higher than 0.3g/L delayed chestnut browning by significantly inhibiting the PPO activity (P<0.01), and the POD activity was not significantly affected (P>0.05). The binding and inhibition modes of SA with PPO and POD, determined by AUTODOCK 4.2 and Lineweaver-Burk plots, respectively, established SA as a competitive inhibitor of PPO.

    Abstract Not only did the criminal corpse have actual medicinal and magical power for Europeans, it also had social and cultural meaning as an object, a curio or secular relic. This paper considers the appeal of notorious bodies. From books bound in the skin of a criminal, to preserved and exhibited heads, from fragments of the hangman’s rope to the exhibition of the skeleton, the story of the afterlife of criminal bodies and the material culture most immediately associated with them begins with the collection and exchange of bodies and moves into contemporary preoccupations with authenticity. This paper considers the bodies of three notorious criminals of the eighteenth century: Eugene Aram, William Burke and William Corder. It ends with some reflections on the glamour of the authentic body of a notorious or celebrated individual – using the response to the discovery of the body of Richard III as an example.

    Notoginseng Radix et Rhizoma (Sanqi), the underground part of Panax notoginseng (Burk.) F. H. Chen (Araliaceae) is commonly used in Chinese medicine for treatment of haemorrhage, haemostasis, swelling, etc. The aerial part including leaves, flowers and fruits are also applied for similar functions. Triterpenoid saponins are considered to be responsible for the biological activities of Sanqi. Up to date, more than 100 saponins have been isolated from theroots, rhizomes, leaves, flowers and fruits of P. notoginseng. The reported saponins can be classified into protopanaxadiol (PPD), protopanaxatriol (PPT), C17 side-chain varied and other types, according to the skeletons of the aglycons. The present review summarizes the saponins isolated from P. notoginseng and their distribution in different medicinal organs, as well as the pharmacological actions on cardiovascular system.

    Since ancient times, creativity, genius, or special artistic accomplishments have been a topic of curiosity. The case presentation that follows describes a painters resistance to success. The patient's developmental history associated with issues of maternal deprivation and paternal abuse had an effect in her artistic creation. Furthermore, her difficulties with achievement and acknowledgment of audience attention were defenses to sabotage her creativity. Her economic struggle was another ingredient used defensively for fear of success. As suggested by Ambers and Burke (2000), artistically inclined individuals have greater fluidity of self-other boundaries, more preoccupation with early separation-individuation issues and are more vulnerable to self-fragmentations anxiety. The patient presented manifests some of these symptoms. However, needing to work full-time to support herself, and painting only in spare time, added to her resistances. V's frustrations, anxieties, and guilt related to her creation are explored.

    The structural, electronic, and magnetic properties of single layers of Iron Dichloride (FeCl{sub 2}) were calculated using first principles calculations. We found that the 1T phase of the single layer FeCl{sub 2} is 0.17 eV/unit cell more favorable than its 1H phase. The structural stability is confirmed by phonon calculations. We found that 1T-FeCl{sub 2} possess three Raman-active (130, 179, and 237 cm{sup −1}) and one infrared-active (279 cm{sup −1}) phonon branches. The electronic band dispersion of the 1T-FeCl{sub 2} is calculated using both gradient approximation of Perdew-Burke-Ernzerhof and DFT-HSE06 functionals. Both functionals reveal that the 1T-FeCl{sub 2} has a half-metallic ground state with a Curie temperature of 17 K.

    A series of aloe-emodin derivatives were synthesized and evaluated as xanthine oxidase inhibitors. Among them, four aloe-emodin derivatives showed significant inhibitory activities against xanthine oxidase. The compound 4,5-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2-carbaldehyde (A1) possessed the best xanthine oxidase inhibitory activity with IC50 of 2.79 μM. Lineweaver-Burk plot analysis revealed that A1 acted as a mixed-type inhibitor for xanthine oxidase. The docking study revealed that the molecule A1 had strong interactions with the active site of xanthine oxidase and this result was in agreement with kinetic study. Consequently, compound A1 is a new-type candidate for further development for the treatment of gout.

    We measured the ratio of the fission probabilities of {sup 234}U* relative to {sup 236}U* formed via an ({alpha},{alpha}{prime}) direct reactions using the STARS array at the 88-inch cyclotron at the Lawrence Berkeley National Laboratory. This ratio has a shape similar to the ratio of neutron capture probabilities from {sup 233}U(n; f) and {sup 235}U(n; f), indicating the alpha reactions likely formed a compound nucleus. This result indicates that the ratios of fission exit channel probabilities for two actinide nuclei populated via ({alpha}, {alpha}{prime}) can be used to determine an unknown fission cross section relative to a known one. The validity of the External Surrogate Ratio Method (ESRM) is tested and the results support the conclusions of Burke et al. [1].

    Based on first principle calculation when Ceperley-Alder and Perdew-Burke-Ernzerh type exchange-correlation energy functional were adopted to LSDA and GGA calculation, electronic properties of organometallic honeycomb lattice as a two-dimensional topological insulator was calculated. In the presence of spin-orbit interaction bulk band gap of organometallic lattice with heavy metals such as Au, Hg, Pt and Tl atoms were investigated. Our results show that the organometallic topological insulator which is made of Mercury atom shows the wide bulk band gap of about ∼120 meV. Moreover, by fitting the conduction and valence bands to the band-structure which are produced by Density Functional Theory, spin-orbit interaction parameters were extracted. Based on calculated parameters, gapless edge states within bulk insulating gap are indeed found for finite width strip of two-dimensional organometallic topological insulators.

    2015-01-01

    As a popular contemporary text, the appeal of cable television's Mad Men (AMC) lies in its capacity to highlight the differences between 1960s sensibilities and 21st-century assumptions. Viewers can enjoy a sense of superiority by recognizing the "folly" of the beliefs and actions of the characters with the benefit of historic hindsight, as well as noting the evolution of technology, philosophy, and human rights. Health-related scenes and themes in the series are a particularly interesting focus for analysis. We employ Burke's four master tropes as an analytical lens and argue that the dominant dramatic technique of irony, particularly in the form that we call strategic anachronism-derived from an audience's enjoyment of historical hindsight-highlights the racism, sexism, homophobia, and overall conservatism of the early 1960s while simultaneously serving to obfuscate the ways in which we still have much to critique in the delivery of contemporary health care and other body politics.

    We present Density Functional Theoretical (DFT) calculations of the electronic properties of scintillator material BaI{sub 2} under pressure which were carried out using Perdew-Burke-Ernzerhof genralized gradient approximation. We found that BaI{sub 2} is a direct band gap material with band gap calculated as 3.35 eV. The pressure effect on BaI{sub 2} indicates a linear monotonously decreasing band gap and increasing valence band width with pressure. We have observed the shifting of band extrema from the Γ point with pressure. The pressure coefficient of band gap is found to be −0.047 eV/GPa. The interatomic ionicity factor of BaI{sub 2} is found to be 0.51. Trends in bonding and ionicity under pressure are also discussed.

    2015-08-01

    A layer model was established to elucidate the mechanism of zinc removal from the metallic mixture of waste printed circuit boards by vacuum distillation. The removal process was optimized by response surface methodology, and the optimum operating conditions were the chamber pressure of 0.1Pa, heating temperature of 923K, heating time of 60.0min, particle size of 70 mesh (0.212mm) and initial mass of 5.25g. Evaporation efficiency of zinc, the response variable, was 99.79%, which indicates that the zinc can be efficiently removed. Based on the experimental results, a mathematical model, which bears on layer structure, evaporation, mass transfer and condensation, interprets the mechanism of the variable effects. Especially, in order to reveal blocking effect on the zinc removal, the Blake-Kozeny-Burke-Plummer equation was introduced into the mass transfer process. The layer model can be applied to a wider range of metal removal by vacuum distillation.

    Foeniculum vulgare fruits are routinely consumed for their carminative and mouth freshening effect. The plant was evaluated for aldose reductase inhibition and anti-diabetic action. Bioguided fractionation using silica gel column chromatography, HPLC, and GC-MS analysis revealed trans-anethole as the bioactive constituent possessing potent aldose reductase inhibitory action, with an IC50 value of 3.8μg/ml. Prolonged treatment with the pet ether fraction of the F. vulgare distillate demonstrated improvement in blood glucose, lipid profile, glycated haemoglobin and other parameters in streptozotocin-induced diabetic rats. Trans-anethole could effectively show anti-cataract activity through the increase in soluble lens protein, reduced glutathione, catalase and SOD activity on in vitro incubation of the eye lens with 55mM glucose. Trans-anethole demonstrated noncompetitive to mixed type of inhibition of lens aldose reductase using Lineweaver Burk plot.

    In the present study, the overall economic impact of hull fouling on a mid-sized naval surface ship (Arleigh Burke-class destroyer DDG-51) has been analyzed. A range of costs associated with hull fouling was examined, including expenditures for fuel, hull coatings, hull coating application and removal, and hull cleaning. The results indicate that the primary cost associated with fouling is due to increased fuel consumption attributable to increased frictional drag. The costs related to hull cleaning and painting are much lower than the fuel costs. The overall cost associated with hull fouling for the Navy's present coating, cleaning, and fouling level is estimated to be $56M per year for the entire DDG-51 class or $1B over 15 years. The results of this study provide guidance as to the amount of money that can be reasonably spent for research, development, acquisition, and implementation of new technologies or management strategies to combat hull fouling.

    The aim of this article is to evaluate if body awareness is important to improve the writing ability before using the splints. Twelve patients with writer’s cramp were evaluated by a specialist in movement disorders. The Burke-Fahn-Marsden Scale (BFM), the Jedynak Protocol and the Analog Pain Scale were used. The rehabilitation training was administered over an eight-week period, in two phases of four weeks each, twice a week. Each session would last 60 minutes. A significant improvement was shown, not only in the motor, but also in the pain perception, through the BFM scale, the Jedynak Protocol and the Analog Pain Scale. Therefore, we conclude that the motor training, thanks to the body awareness and immobilization by splints of the affected dystonic musculature, led to an important improvement in the writer’s cramp writing.

    Antrodia cinnamomea is a highly valued folk medicine used for liver cancer, a disease often caused by the long term infection of hepatitis C virus (HCV). In the present study, the maleic and succinic acid constituents (antrodins A-E) of this medicinal fungus, the in vivo metabolites of antrodin C and the analogue of one of the metabolites were tested for their inhibitory activity on HCV protease. Most of the compounds showed potent inhibitory activity, with antrodin A being the most potent (IC(50) = 0.9 microg/mL). Antrodin A was isolated as one of the constituents of A. cinnamomea and was also detected as an in vivo metabolite of the major constituent antrodin C. The mode of inhibition for antrodin A on HCV protease was revealed by a Lineweaver-Burk plot as competitive inhibition. These results strongly support the use of this folk medicine for liver cancer and HCV infection which is a global problem.

    Burke and Franklin (1955) discovered radio emissions from Jupiter at 22.2 MHz. Subsequent observations established the strong control of the decametric emissions by the satellite Io. The Voyager encounters with Jupiter in 1979 have resulted in a dramatic increase in detailed knowledge of the plasma properties of the Jovian magnetosphere. The Io plasma torus is discussed, taking into account the Voyager plasma science experiment, positive-ion temperatures in the torus, electron distribution functions in the torus, elementary-charge concentrations in the torus, positive-ion composition in the torus, and plasma velocities in the torus. The Io flux tube is considered along with the middle magnetosphere and the outer magnetosphere. Attention is given to the sources of plasma, aspects of diffusive transport, questions of inertial loading, and the existence of nonazimuthal flow velocities in the middle magnetosphere.

    In an earlier communication we have developed a recursion based approach to the study of phase stability and transition of binary alloys [K. Tarafder, M. Rahaman, D. Paudyal, B. Sanyal, O. Eriksson, A. Mookerjee, Physica B 403 (2000) 4111]. We had combined the recursion method introduced by Haydock et al. [J. Phys. C Solid State Phys. 5 (1972) 2485] and the our augmented space approach [A. Mookerjee, J. Phys. C Solid State Phys. 6 (1973) 1340] with the orbital peeling technique proposed by Burke [Surf. Sci. 58 (1976) 349] to determine the small energy differences involved in the discussion of phase stability. We extend that methodology for the study of MnCr alloys.

    Hydrolysates containing angiotensin-I converting enzyme (ACE)-inhibitory peptide were prepared from Enteromorpha clathrata protein using alcalase. The hydrolysates were fractionated into two molecular-weight ranges (below and above 10kDa) by ultrafiltration. The below-10kDa fraction showed higher ACE-inhibitory activity and was subsequently purified by Sephadex G-15 gel filtration chromatography. The structure of active peptide was identified as Pro-Ala-Phe-Gly by HPLC-Q-TOF-MS and its IC50 value was 35.9μM. The yield of this peptide from E. clathrata protein was 0.82%. Lineweaver-Burk plots demonstrated that the inhibitory kinetic mechanism of this peptide was non-competitive. Stability study revealed that the purified peptide showed resistance against gastrointestinal proteases. Thus, E. clathrata protein hydrolysate treated with alcalase is a beneficial ingredient of nutraceuticals and pharmaceuticals against hypertension and related diseases.

    Since centuries anatomists have used any course of action in order to get hold of material for dissections, and at the same time avoid prosecution for grave robbery, at times the only way to get hold of cadavers. Stealing newly dead people from the churchyards and offering them for sale to anatomical institutions was not uncommon in the 19th century. "Resurrectionists"--as these thieves were called, as they made the dead "alive"--were seen as necessary for the teaching of anatomy in Victorian Britain. In the 1820s a scandal was revealed in Scotland, when it was discovered that some people even committed murder to make money from supplying anatomists with human cadavers. Two men, William Burke and William Hare, became particularly notorious because of their "business" with the celebrated anatomist Robert Knox in Edinburgh.

  17. Asymptotic analysis with reduced chemistry for the burning of n-heptane droplets

    Card, J. M.; Williams, F. A.

    1992-01-01

    The method of rate-ratio asymptotics is used with reduced chemistry to analyze the flame structure and extinction of an isolated n-heptane droplet burning under quasisteady, spherically symmetrical conditions. The outer transport zones are described by the classical Burke-Schumann solution. The inner reaction zone consists of a thin layer, on the rich side of the flame, where the fuel is consumed, and on the lean side, a broader but still asymptotically thin oxidation layer, where H2 and CO are consumed. Special attention is given to differences in predictions of extinction conditions, caused by different chemical-kinetic approximations in the reduced chemistry, including fuel-chemistry effects through molecules containing more than one carbon atom. From the analysis, extinction diameters for n-heptane droplets are estimated for different pressures and ambient oxygen concentrations. The results show that extinction diameters are extremely sensitive to the number of radicals consumed in breaking down each fuel molecule.

    A theoretical study of structural, electronic and optical properties of Ag2S is presented using the full potential linearized augmented plane wave (FP-LAPW) method within density functional theory (DFT). In this approach, the modified Becke Johnson (MBJ) potential coupled with Local Density Approximation (LDA) was used for the exchange-correlation potential calculation. Ground state properties are determined for the bulk material in monoclinic phase. Band structure reveals that this compound is a direct energy band gap semiconductor. MBJLDA results for the band gap of this compound are much better than those obtained using LDA, Perdew-Burke-Ernzerhof generalized gradient approximation (PBE-GGA) and Engel-Vosko's GGA (EV-GGA). A very good agreement is observed between MBJLDA band gap and corresponding experimental values as compared to other calculations. Optical constants including the dielectric function, refractive index, extinction coefficient, electron energy loss function, reflectivity and absorption coefficient are obtained and discussed.

    The calculations based on linear combination of atomic orbitals basis functions as implemented in CRYSTAL09 computer code have been performed for cubic, tetragonal, orthorhombic, and rhombohedral modifications of BaTiO(3) crystal. Structural and electronic properties as well as phonon frequencies were obtained using local density approximation, generalized gradient approximation, and hybrid exchange-correlation density functional theory (DFT) functionals for four stable phases of BaTiO(3). A comparison was made between the results of different DFT techniques. It is concluded that the hybrid PBE0 [J. P. Perdew, K. Burke, M. Ernzerhof, J. Chem. Phys. 1996, 105, 9982.] functional is able to predict correctly the structural stability and phonon properties both for cubic and ferroelectric phases of BaTiO(3). The comparative phonon symmetry analysis in BaTiO(3) four phases has been made basing on the site symmetry and irreducible representation indexes for the first time.

    We present the first-ever experimental Compton profile of Laves phase ZrFe2 using indigenous 20 Ci 137Cs Compton spectrometer. To annotate the experimental electron momentum density, we have calculated the theoretical Compton profiles using density functional theory (DFT) and hybridization of Hartree-Fock and DFT within linear combination of atomic orbitals (LCAO) method. The spin-polarized energy bands and density of states are computed using LCAO and full potential-linearized augmented plane wave methods. The revised Perdew-Burke-Ernzerhof functional (for solids) based theoretical profile gives a marginally better agreement with the experimental profile as compared to other approximations considered in the present work. The Fermi surface topology of ZrFe2 is explained in terms of majority- and minority-spin energy bands.

    Using the van der Waals density functional with C09 exchange (vdW-DF-C09), which has been applied to describing a wide range of dispersion-bound systems, we explore the physical properties of prototypical ABO3 bulk ferroelectric oxides. Surprisingly, vdW-DF-C09 provides a superior description of experimental values for lattice constants, polarization and bulk moduli, exhibiting similar accuracy to the modified Perdew-Burke-Erzenhoff functional which was designed specifically for bulk solids (PBEsol). The relative performance of vdW-DF-C09 is strongly linked to the form of the exchange enhancement factor which, like PBEsol, tends to behave like the gradient expansion approximation for small reduced gradients. These results suggest the general-purpose nature of the class of vdW-DF functionals, with particular consequences for predicting material functionality across dense and sparse matter regimes.

    NASA's Traffic Aware Planner (TAP) is a cockpit decision support tool that provides aircrew with vertical and lateral flight-path optimizations with the intent of achieving significant fuel and time savings, while automatically avoiding traffic, weather, and restricted airspace conflicts. A key step towards the maturation and deployment of TAP concerned its operational evaluation in a representative flight environment. This Systems Engineering Management Plan (SEMP) addresses the test-vehicle design, systems integration, and flight-test planning for the first TAP operational flight evaluations, which were successfully completed in November 2013. The trial outcomes are documented in the Traffic Aware Planner (TAP) flight evaluation paper presented at the 14th AIAA Aviation Technology, Integration, and Operations Conference, Atlanta, GA. (AIAA-2014-2166, Maris, J. M., Haynes, M. A., Wing, D. J., Burke, K. A., Henderson, J., & Woods, S. E., 2014).

    In this study, we investigated the effects of the drugs, palonosetron hydrochloride, bevacizumab and cyclophosphamide, on human serum paraoxonase-I (hPON1) enzyme activity in in vitro conditions. The enzyme was purified ∼231-fold with 34.2% yield by using ammonium sulphate precipitation, DEAE-Sephadex A-50 ion-exchange chromatography and Sephadex G-200 gel-filtration chromatography from human serum. hPON1 exhibited a single protein band on the SDS polyacrylamide gel electrophoresis. The inhibition studies were performed on paraoxonase activity of palonosetron hydrochloride, bevacizumab and cyclophosphamide. Ki constants were found as 0.033±0.001, 0.054±0.003 mM and 3.419±0.518 mM, respectively. Compared to the inhibition rates of the drugs, palonosetron hydrochloride has the maximum inhibition rate. However, inhibition mechanisms of the drugs were determined as noncompetitive by Lineweaver-Burk curves.

    A protease from newly isolated Bacillus circulans M34 was purified by Q-Sepharose anion exchange chromatography and Sepharose-bacitracin affinity chromatography followed by (NH4)2SO4 precipitation. The molecular mass of the purified enzyme was determined using SDS-PAGE. The optimum pH and temperature for protease activity were 11 and 50°C, respectively. The effect of various metal ions on protease activity was investigated. Alkaline protease from Bacillus circulans M34 wase activated by Zn(2+), Cu(2+) and Co(2+) up to 31%. The purified protease was found to be stable in the organic solvents, surfactants and oxidizing agent. The substrate specificity of purified protease was investigated towards different substrates. The protease was almost completely inhibited by the serine protease inhibitor phenylmethanesulfonyl fluoride. The kinetic parameters of the purified protease, maximum rate (Vmax) and Michaelis constant (Km), were determined using a Lineweaver-Burk plot.

    Stability and electronic properties of zigzag (3 ≤ n ≤ 16) gallium phosphide nanotubes (GaP NTs) have been analyzed by employing a systematic ab-intio approach based on density functional theory using generalized gradient approximation with revised Perdew Burke Ernzerhoff type parameterization. Diameter dependence of bond length, buckling, binding energy, and band gap has been investigated and the analysis shows that the bond length and buckling decreases with increasing diameter of the tube, highest binding energy of (16, 0) confirms this as the most stable amongst all the NTs taken into consideration. The present GaP NTs shows direct band gap and it increases with diameter of the tubes. Using a two probe model for (4, 0) NT the I-V relationship shows an exponential increase in current on applying bias voltage beyond 1.73 volt.

  7. Simulations of a modified SOP model applied to retrospective revaluation of human causal learning.

    2005-05-01

    Dickinson and Burke (1996) proposed a modified version of Wagner's (1981) SOP associative theory to explain retrospective revaluation of human causal judgments. In this modified SOP (MSOP), excitatory learning occurs when cue and outcome representations are either both directly activated or both associatively activated. By contrast, inhibitory learning occurs when one representation is directly activated while the other is associatively activated. Finite node simulations of MSOP yielded simple acquisition, overshadowing, blocking, and inhibitory learning under forward contingencies. Importantly, retrospective revaluation was predicted in the form of unovershadowing and backward inhibitory learning. However, MSOP did not yield backward blocking. These predictions are evaluated against the relevant empirical evidence and contrasted with the predictions of other associative theories that have been applied to retrospective revaluation of human causal and predictive learning.

    2016-12-01

    Density functional theory using the Perdew-Burke-Ernzerhof functional and the small displacement method was used to calculate the quasiharmonic phonon density of states (DOS) for 69 ordered structures in the Mo-Ru substitutional alloy system to estimate the effect of vibrational contributions to the free energy of formation. These structures were used to determine interaction parameters in the cluster expansion approximation up to triplet sets to incorporate the vibrational contribution into the configurational energy of formation for the randomly mixed system. The free energies calculated using this approximation are shown to resolve lingering disagreement between reported theoretical and experimental results, and the stabilizing effect of vibrational entropy is observed to improve theoretical predictions of the Mo-Ru phase diagram.

    The present study examined associations between stress and problematic alcohol use among US Navy members anticipating deployment, whether depressive symptoms mediated the stress-alcohol link, and whether social support and relationship satisfaction moderated associations between stress, depressive symptoms, and problematic alcohol use. Participants were 108 US Navy members assigned to an Arleigh Burke-class destroyer anticipating an 8-month deployment after Operational Enduring Freedom/Operation Iraqi Freedom. Stress was indirectly related to problematic alcohol use such that higher levels of stress were associated with higher levels of depressive symptoms, which were further associated with higher levels of alcohol use. The indirect effect of stress to problematic alcohol use via depressive symptoms was tested at different levels of social support and relationship satisfaction. At higher levels of social support and relationship satisfaction, the association between stress and problematic alcohol use via depressive symptoms decreased. Results help identify targets for alcohol prevention efforts among current military members.

    2015-04-01

    New findings from deep Greenland ice cores and airborne radio echo sounding (RES) images show that basal ice flow is very unstable, and a basal layer of disturbed ice is often observed. At NEEM, Greenland this folding occurs at the boundary between the Eemian and glacial ice regimes, suggesting that differences in physical properties of the ice play a role in the disturbance. Past work in metallurgy (Burke, 1957) and ice (Hammer et al., 1978; Langway et al., 1988; Dahl-Jensen et al., 1997), suggests that impurity content controls grain evolution, and therefore deformation, which we hypothesize to be analogous to the differences in ice flow seen deep in the NEEM ice core. Here we present results of fabric, grain size, impurity content, and deformation studies from samples above and below this unstable boundary in the ice sheet.

    2015-01-01

    Retrospective revaluation refers to an increase (or decrease) in responding to conditioned stimulus (CS X) as a result of decreasing (or increasing) the associative strength of another CS (A) with respect to the unconditioned stimulus (i.e., A-US) that was previously trained in compound with the target CS (e.g., AX−US or just AX). We discuss the conditions under which retrospective revaluation phenomena are most apt to be observed and their implications for various models of learning that are able to account for retrospective revaluation (e.g., Dickinson and Burke, 1996; Miller and Matzel, 1988; Van Hamme and Wasserman, 1994). Although retroactive revaluation is relatively parameter specific, it is seen to be a reliable phenomenon observed across many tasks and species. As it is not anticipated by many conventional models of learning (e.g., Rescorla and Wagner, 1972), it serves as a critical benchmark for evaluating traditional and newer models. PMID:26342855

The norharman showed a potent inhibition against α-glucosidase enzyme in a concentration dependent manner with an IC50 value of 0.27 mM for maltase and 0.41 mM for sucrase, respectively. A Lineweaver-Burk plot revealed that norharman inhibited α-glucosidase enzyme uncompetitively, with a Ki value of 0.13 mM.

    The widespread popularity of density functional theory has given rise to an extensive range of dedicated codes for predicting molecular and crystalline properties. However, each code implements the formalism in a different way, raising questions about the reproducibility of such predictions. We report the results of a community-wide effort that compared 15 solid-state codes, using 40 different potentials or basis set types, to assess the quality of the Perdew-Burke-Ernzerhof equations of state for 71 elemental crystals. We conclude that predictions from recent codes and pseudopotentials agree very well, with pairwise differences that are comparable to those between different high-precision experiments. Older methods, however, have less precise agreement. Our benchmark provides a framework for users and developers to document the precision of new applications and methodological improvements.

    Recent implementational improvements of the generalized gradient approximation (GGA) have led to a simplified version.(J. P. Perdew, K. Burke, and M. Ernzerhof, Phys. Rev. Lett. 77), 3865 (1996) We have performed detailed calculations on the geometries, atomization energies, vibrational energies, and infrared and Raman spectra of many first- and second- row dimers as well as some polyatomic molecules. For atomization and vibrational energies, we find that the simplified version of GGA leads to results similar to the original version. We explain why the GGA-induced changes of hydrogenic bonding and vibrations are different than for the other atoms in the periodic table but still are an improvement over the local approximations to density-functional theory. Special emphasis on problem cases such as Cr2 and noble gas molecules will be discussed in greater detail.

    Theoretical models of an axisymmetric laminar diffusion flame are discussed, with an emphasis on the behavior of such flames at increasing pressures. The flame-sheet or Burke-Schumann model (in terms of Bessel functions) and various boundary layer numerical solutions are presented and their results compared with experimental data. The most promising theoretical model combines the numerical flow field solution of the Patankar-Spalding computer code with the Pratt-Wormeck chemical reaction subroutine. The flame shapes for pressures of 1, 5, 10, 20, and 50 atmospheres were computed and agree remarkably well with experimental data. There is a noticeable shape change with pressure, believed to be a result of buoyancy effects. The chemical concentration profiles do not exhibit much dependence on pressure, a reflection of the fact that only one chemical mechanism was utilized at all pressures.

    A zone of structural disruption and complexity along the Pacific coast margin of the Alaska Peninsula (fig. 41) may be related to the Alaska Peninsula and the Chugach terrane boundary. The best exposure of this zone is located on the east shore of Humpback Bay (figs. 42, 43; also Burk, 1965, pl. 8, fig. 4); other exposures are located on the east side of Ivanof Bay, the north and south sides of Lefthand Bay, and in other coastal localities in the area. In some places, such as on the Kupreanof Peninsula, it is not recognized. This zone may extend discontinuously for 110-160 km along the coast; the width of the zone varies from 0.5 to 1 km. Our current data and tentative interpretations are described here, pending completion of additional field research, laboratory, and office studies.

    First-principles calculations of the band offsets between Cu(2)ZnSnS(4) (CZTS) and XS (X = Cd, Zn) are performed. While the interface dipole contribution for the band offsets is calculated using the Perdew-Burke-Ernzerhof functional, the Heyd-Scuseria-Ernzerhof hybrid functional is employed to introduce the quasiparticle corrections to the band offsets. The calculated conduction band offset between CZTS and CdS is 0.2 eV, validating CdS for the buffer layer of the CZTS solar cell. The small conduction band offset stems from the band gap narrowing of CdS under the interface strain caused by the lattice misfit with CZTS. A large valence band offset over 0.9 eV between CZTS and ZnS indicates that precipitated ZnS is regarded as an inactive insulator phase in CZTS absorbers.

The anion position parameters u are also predicted using the model of Abrahams and Bernstein and the results seem to be trustworthy as compared to the experimental and theoretical values. The total and part density of states are discussed which follow the common rule of the conventional semiconductors. The static dielectric tenser and refractive index are summarized compared with available experimental and theoretical values. Also the spectra of the dielectric functions, refractive index, reflectance, absorption coefficient and real parts of photoconductivity are discussed in details.

    The radical cations of piperazine, morpholine, thiomorpholine, and thioxane were investigated by electron paramagnetic resonance (EPR) and electron-nuclear double resonance (ENDOR) spectroscopy in a solid Freon matrix. Optimized geometry and magnetic parameters of the radical cations were calculated using a density functional theory (DFT)/Perdew-Burke-Ernzerhof (PBE) method. Both experimental and theoretical results suggest that all the studied species adopt chair (or distorted chair) conformations. No evidence for the boat conformers with intramolecular sigma-bonding between heteroatoms were obtained. In the cases of morpholine and thioxane, the oxygen atoms are characterized by relatively small spin populations, whereas a major part of spin density is located at N and S atoms, respectively. The thiomorpholine radical cation exhibits nearly equal spin population of N and S atoms. In most cases (except for thioxane), the calculated magnetic parameters agree with the experimental data reasonably well.

    One of the practitioners of probably the oldest surgical specialty, ophthalmic, was the eminent Scottish ophthalmologist, Sir William Mackenzie. Educated in Edinburgh, he moved to Glasgow, and described and named sympathetic ophthalmia before the time of the ophthalmoscope, well defining his powers of observation and deduction. Founding the Glasgow Eye Infirmary, his 'Practical Treatise on Diseases of the Eye' appeared in English in four editions (1850-1884) and in French and German. In this also appears the first full and clear account of glaucoma. Both he and the illustrator of his book, Wharton Jones, moved to Glasgow because of rather indefinite connections with Robert Knox, the anatomist, who was allegedly helped by the bodysnatchers, Burke and Hare. Mackenzie and his book were highly regarded before the revolutionary ophthalmoscope. He was knighted and appointed Surgeon Oculist to the Queen in Scotland.
