    1995-12-01

    Full Text Available This article explores marginality theory as it was first proposed in  the social sciences, that is related to persons caught between two competing cultures (Park; Stonequist, and, then, as it was developed in sociology as related to the poor (Germani and in anthropology as it was related to involuntary marginality and voluntary marginality (Victor Turner. It then examines a (normative scheme' in antiquity that creates involuntary marginality at the macrosocial level, namely, Lenski's social stratification model in an agrarian society, and indicates how Matthean language might fit with a sample inventory  of socioreligious roles. Next, it examines some (normative schemes' in  antiquity for voluntary margi-nality at the microsocial level, namely, groups, and examines how the Matthean gospel would fit based on indications of factions and leaders. The article ,shows that the author of the Gospel of Matthew has an ideology of (voluntary marginality', but his gospel includes some hope for (involuntary  marginals' in  the  real world, though it is somewhat tempered. It also suggests that the writer of the Gospel is a (marginal man', especially in the sense defined by the early theorists (Park; Stone-quist.

  14. Fine-mapping of immunodominant linear B-cell epitopes of the Staphylococcus aureus SEB antigen using short overlapping peptides.

    Directory of Open Access Journals (Sweden)

    Zhuo Zhao

    Full Text Available Staphylococcal enterotoxin B (SEB is one of the most potent Staphylococcus aureus exotoxins (SEs. Due to its conserved sequence and stable structure, SEB might be a good candidate antigen for MRSA vaccines. Although cellular immune responses to SEB are well-characterized, much less is known regarding SEB-specific humoral immune responses, particularly regarding detailed epitope mapping. In this study, we utilized a recombinant nontoxic mutant of SEB (rSEB and an AlPO4 adjuvant to immunize BALB/c mice and confirmed that rSEB can induce a high antibody level and effective immune protection against MRSA infection. Next, the antisera of immunized mice were collected, and linear B cell epitopes within SEB were finely mapped using a series of overlapping synthetic peptides. Three immunodominant B cell epitopes of SEB were screened by ELISA, including a novel epitope, SEB205-222, and two known epitopes, SEB97-114 and SEB247-261. Using truncated peptides, an ELISA was performed with peptide-KLH antisera, and the core sequence of the three immunodominant B cell epitopes were verified as SEB97-112, SEB207-222, and SEB247-257. In vitro, all of the immunodominant epitope-specific antisera (anti-SEB97-112, anti-SEB207-222 and anti-SEB247-257 were observed to inhibit SEB-induced T cell mitogenesis and cytokine production from splenic lymphocytes of BALB/c mice. The homology analysis indicated that SEB97-112 and SEB207-222 were well-conserved among different Staphylococcus aureus strains. The 3D crystal structure of SEB indicated that SEB97-112 was in the loop region inside SEB, whereas SEB207-222 and SEB247-257 were in the β-slice region outside SEB. In summary, the fine-mapping of linear B-cell epitopes of the SEB antigen in this study will be useful to understand anti-SEB immunity against MRSA infection further and will be helpful to optimize MRSA vaccine designs that are based on the SEB antigen.

  15. Proton exchange membranes based on PVDF/SEBS blends

    Energy Technology Data Exchange (ETDEWEB)

    Proton-conductive polymer membranes are used as an electrolyte in the so-called proton exchange membrane fuel cells. Current commercially available membranes are perfluorosulfonic acid polymers, a class of high-cost ionomers. This paper examines the potential of polymer blends, namely those of styrene-(ethylene-butylene)-styrene block copolymer (SEBS) and polyvinylidene fluoride (PVDF), in the proton exchange membrane application. SEBS/PVDF blends were prepared by twin-screw extrusion and the membranes were formed by calendering. SEBS is a phase-segregated material where the polystyrene blocks can be selectively functionalized offering high ionic conductivity, while PVDF insures good dimensional stability and chemical resistance to the films. Proton conductivity of the films was obtained by solid-state grafting of sulfonic acid moieties. The obtained membranes were characterized in terms of conductivity, ionic exchange capacity and water uptake. In addition, the membranes were characterized in terms of morphology, microstructure and thermo-mechanical properties to establish the blends morphology-property relationships. Modification of interfacial properties between SEBS and PVDF was found to be a key to optimize the blends performance. Addition of a methyl methacrylate-butyl acrylate-methyl methacrylate block copolymer (MMA-BA-MMA) was found to compatibilize the blend by reducing the segregation scale and improving the blend homogeneity. Mechanical resistance of the membranes was also improved through the addition of this compatibilizer. As little as 2wt.% compatibilizer was sufficient for complete interfacial coverage and lead to improved mechanical properties. Compatibilized blend membranes also showed higher conductivities, 1.9x10{sup -2} to 5.5x10{sup -3}Scm{sup -1}, and improved water management. (author)

  16. The Gospel of Matthew: Reconfigured Torah

    Directory of Open Access Journals (Sweden)

    Richard B. Hays

    2005-10-01

    Full Text Available This essay surveys the evangelist Matthew’s reading of Israel’s Scripture. Rather than focusing only on Matthew’s distinctive formula quotations, we must observe the subtler ways that Matthew evokes scriptural images and patterns. The essay highlights four major aspects of Matthew’s reading of Scripture. (1 Matthew reads Israel’s Scripture as a story that highlights election, kingship, exile, and messianic salvation as the end of exile. (2 Matthew reconfigures Torah into a call for radical transformation of the heart. (3 Matthew highlights Scripture’s call for mercy, particularly by emphasizing Hosea 6:6 as the hermeneutical key to Torah. (4 Matthew interprets the mission to the Gentiles as the fulfilment of Israel’s destiny and the active embodiment of the authority of the Son of Man (Dn 7:13-14 over the whole world. Jointly taken, these strategies of interpretation produce a striking reconfiguration of Israel’s Torah.

    2013-11-15

    Staphylococcus aureus plays an important role in numerous human cases of food poisoning, soft tissue, and bone infections, as well as potentially lethal toxic shock. This common bacterium synthesizes various virulence factors that include staphylococcal enterotoxins (SEs). These protein toxins bind directly to major histocompatibility complex class II on antigen-presenting cells and specific Vβ regions of T-cell receptors, resulting in potentially life-threatening stimulation of the immune system. Picomolar concentrations of SEs ultimately elicit proinflammatory cytokines that can induce fever, hypotension, multi-organ failure, and lethal shock. Various in vitro and in vivo models have provided important tools for studying the biological effects of, as well as potential vaccines/therapeutics against, the SEs. This review succinctly presents known physical and biological properties of the SEs, including various intervention strategies. In particular, SEB will often be portrayed as per biodefense concerns dating back to the 1960s.

Hierdie artikel bespreek die sendingdiskoers in Matteus 10 en beweer dat dit ’n enkele sendingopdrag is wat twee diskrete tydperiodes dek wanneer die evangelie van die koninkryk verkondig is. Hierdie sendingopdrag is tydens Christus se eerste koms aan die 12 apostels gegee om die evangelie van die koninkryk net in Israel te verkondig. Omdat ‘hierdie geslag’ die onvergeeflike sonde gedoen het, is hierdie sendingopdrag uitgestel en sal hervat word tydens die Verdrukking wanneer die komende Koning Joodse boodskappers sal magtig om weer die evangelie van die koninkryk te verkondig – hierdie keer tot getuienis vir al die nasies.

    2008-01-01

    In this study, peptides were selected to recognize staphylococcal enterotoxin B (SEB) which cause food intoxication and can be used as a biological war agent. By using commercial M13 phage library, single plaque isolation of 38 phages was done and binding affinities were investigated with phage-ELISA. The specificities of the selected phage clones showing high affinity to SEB were checked by using different protein molecules which can be found in food samples. Furthermore, the affinities of three selected phage clones were determined by using surface plasmon resonance (SPR) sensors. Sequence analysis was realized for three peptides showing high binding affinity to SEB and WWRPLTPESPPA, MNLHDYHRLFWY, and QHPQINQTLYRM amino acid sequences were obtained. The peptide sequence with highest affinity to SEB was synthesized with solid phase peptide synthesis technique and thermodynamic constants of the peptide-SEB interaction were determined by using isothermal titration calorimetry (ITC) and compared with those of antibody-SEB interaction. The binding constant of the peptide was determined as 4.2 ± 0.7 x 10 5 M -1 which indicates a strong binding close to that of antibody

  7. The Gospel of Matthew and women

    Directory of Open Access Journals (Sweden)

    P.J.J. Botha

    2003-08-01

    Full Text Available Matthew obviously reveals no concern with gender roles and issues about female leadership. This Gospel simply perceives such issues from the perspective of conventional patriarchal terms within the Roman household ideology, at best believing “collegiality” to be proper for his community. In order to avoid biblicistic and/or fundamentalistic theological reflection these issues should be acknowledged in our “wrestling” with Scripture. At the same time Matthew’s vision of God and the abundant righteousness demanded allow us to go beyond Matthew’s treatment of women and radicalise not only the implicit call to equity in our tradition but even our own context’s emphasis on equality.

  10. IL-2 regulates SEB induced toxic shock syndrome in BALB/c mice.

    2009-12-01

    Full Text Available Toxic Shock Syndrome (TSS is characterized by fever, rash, hypotension, constitutional symptoms, and multi-organ involvement and is caused by Staphylococcus aureus enterotoxins such as Staphylococcal Enterotoxin B (SEB. SEB binds to the MHC-IIalpha chain and is recognized by the TCRbeta chain of the Vbeta8 TCR(+ T cells. The binding of SEB to Vbeta chain results in rapid activation of T cells and production of inflammatory cytokines, such as Interleukin-2 (IL-2, Interferon-gamma and Tumor Necrosis Factor-alpha which mediate TSS. Although IL2 was originally identified as the T cell growth factor and was proposed to contribute to T cell differentiation, its role in TSS remains unexplored.Mice were injected with D-Gal (25 mg/mouse. One hour after D-Galactosamine (D-Gal injection each mouse was injected with SEB (20 microg/mouse. Mice were then observed for 72 hrs and death was recorded at different times. We tested Interleukin-12, IFNgamma, and IL-2 deficient mice (IL-2(-/-, but only the IL-2 deficient mice were resistant to SEB induced toxic shock syndrome. More importantly reconstitution of IL-2 in IL-2 deficient mice restored the shock. Interestingly, SEB induced IL-2 production from T cells was dependent on p38MAPK activation in macrophages as inhibition of it in macrophages significantly inhibited IL-2 production from T cells.This study shows the importance of IL -2 in TSS which has not been previously explored and it also shows that regulating macrophages function can regulate T cells and TSS.

  12. Evocative allusions in Matthew: Matthew 5:5 as a test case

    Directory of Open Access Journals (Sweden)

    Robert L. Brawley

    2003-10-01

    Full Text Available Combining theories of intertextuality and abductive reasoning, this article demonstrates the figurative nature of scriptural allusions in Matthew. Allusions form figurations that open new perspectives for readers inasmuch as the source text and the new text stand in a tensive relationship in which each modifies the other and in which together they evoke meaning beyond the mere sum of the two independent texts. Allusions also form figurations inasmuch as arguments that are analogous to logic. Surprising, original, uncanny correlations between the source text and the new text involve what Charles Peirce called abductive reasoning which also challenges constructs of reality. This article interprets Matthew 5:5 as an allusion to the Abrahamic promise of the inheritance of the land and the blessing of all the families of the earth mediated through Psalm 36 (LXX and describes the figurative nature of the allusion using Harold Bloom’s revisionary ratios. Another version of the article will also be published in Kim, P & Ringe, S (eds, Literary encounters with the reign of God: Essays in honor of Robert C Tannehill, Harrisburg, PA: Trinity Press International (Forthcoming.

    Full Text Available Enterotoxins secreted by S. aureus are known as a food-poisoning agent that is associated with various gastro-intestinal pathological conditions. In this study, a one-step immunodetection method was devised for routine checking of SEB in milk and fruit juices available locally. Antibodies against recombinant SEB were raised, purified, and cross reactivity was checked against clinically important bacteria (Shigella flexneri, Streptococci, Salmonella typhi, Klebsiella and Bacillus subtilis. Purified anti-SEB antibodies were conjugated with gold nanoparticles (Ab-GNPs for direct detection of SEB in samples. SEB (33%, 4.76% and 15% was found in non-sterilized milk (118, sterilized milk (42 and juices (60, respectively. Coagulase, MSA tests and PCR amplification of 725 bp of the SEB gene confirmed the presence of S. aureus in the collected samples positive for SEB. Immunoassay is easy, reliable and less time consuming and will be helpful to detect the SEB in food samples at local level.

    Full Text Available Current earth observation models do not take into account the influence of water salinity on the evaporation rate, even though the salinity influences the evaporation rate by affecting the density and latent heat of vaporization. In this paper, we adapt the SEBS (Surface Energy Balance System model for large water bodies and add the effect of water salinity to the evaporation rate. Firstly, SEBS is modified for fresh-water whereby new parameterizations of the water heat flux and sensible heat flux are suggested. This is achieved by adapting the roughness heights for momentum and heat transfer. Secondly, a salinity correction factor is integrated into the adapted model. Eddy covariance measurements over Lake IJsselmeer (The Netherlands are carried out and used to estimate the roughness heights for momentum (~0.0002 m and heat transfer (~0.0001 m. Application of these values over the Victoria and Tana lakes (freshwater in Africa showed that the calculated latent heat fluxes agree well with the measurements. The root mean-square of relative-errors (rRMSE is about 4.1% for Lake Victoria and 4.7%, for Lake Tana. Verification with ECMWF data showed that the salinity reduced the evaporation at varying levels by up to 27% in the Great Salt Lake and by 1% for open ocean. Our results show the importance of salinity to the evaporation rate and the suitability of the adapted-SEBS model (AquaSEBS for fresh and saline waters.

    Full Text Available Abstract Background The lack of detailed understanding of the mechanism of action of many biowarfare agents poses an immediate challenge to biodefense efforts. Many potential bioweapons have been shown to affect the cellular pathways controlling apoptosis 1234. For example, pathogen-produced exotoxins such as Staphylococcal Enterotoxin B (SEB and Anthrax Lethal Factor (LF have been shown to disrupt the Fas-mediated apoptotic pathway 24. To evaluate how these agents affect these pathways it is first necessary to understand the dynamics of a normally functioning apoptosis network. This can then serve as a baseline against which a pathogen perturbed system can be compared. Such comparisons can expose both the proteins most susceptible to alteration by the agent as well as the most critical reaction rates to better instill control on a biological network. Results We explore this through the modeling and simulation of the Fas-mediated apoptotic pathway under normal and SEB influenced conditions. We stimulated human Jurkat cells with an anti-Fas antibody in the presence and absence of SEB and determined the relative levels of seven proteins involved in the core pathway at five time points following exposure. These levels were used to impute relative rate constants and build a quantitative model consisting of a series of ordinary differential equations (ODEs that simulate the network under both normal and pathogen-influenced conditions. Experimental results show that cells exposed to SEB exhibit an increase in the rate of executioner caspase expression (and subsequently apoptosis of 1 hour 43 minutes (± 14 minutes, as compared to cells undergoing normal cell death. Conclusion Our model accurately reflects these results and reveals intervention points that can be altered to restore SEB-influenced system dynamics back to levels within the range of normal conditions.

Donaldson’s book, Jesus on the mountain: A study in Matthean theology, published in 1985 by JSOT Press, Sheffield, and focused on the mountain motif in the structure and plot of the Gospel of Matthew, in addition to the work of Donaldson on the mountain motif as a literary motif and as theological symbol. The mountain is a primary theological setting for Jesus’ ministry and thus is an important setting, serving as one of the literary devices by which Matthew structured and progressed his narrative. The Zion theological and eschatological significance and Second Temple Judaism serve as the historical and theological background for the mountain motif. The last mountain setting (Mt 28:16–20 is the culmination of the three theological themes in the plot of Matthew, namely Christology, ecclesiology and salvation history.

    Hitherto, as nuclear fission fragments of 252-Cf, one of radioactive matters have been used for elucidation of single event mechanism, this method has a limit for analysis of power MOSFET with long charge collection region (generally, empty layer) and is difficult to form the experiment simulating the space environment, because of their wide LET (Linear Energy Transfer) range and of short flying distance of about 15 micrometer. As a result, some irradiation experiments using an accelerator capable of forming charged particle beam with long flying distance and single energy became essential to elucidate the SEB mechanism. In this paper, an experiment result of SEB phenomenon using high energy accelerator was reported. As a result, following items were found: (1) With increase of impressed charge, collected charge shows two peaks, and also increases, (2) commercial power MOSFET shows about 280 V in SEB resistance, and power MOSFET developed for the space use shows about 320 V, which is improved about 40 V for the commercial one, and so forth.

    Single event irradiation-hardened power MOSFET is the most important device for DC/DC converter in space environment application. Single event gate rupture (SEGR) and single event burnout (SEB), which will degrade the running safety and reliability of spacecraft, are the two typical failure modes in power MOSFETs. In this paper, based on recombination mechanism of interface between oxide and silicon, a novel hardened power MOSFETs structure for SEGR and SEB is proposed. The structure comprises double stagger partial silicon-on-insulator (DSPSOI) layers. Results show that the safety operation area (SOA) of a 130 V N-channel power MOSFET in single event irradiation environment is enhanced by up to 50% when the linear-energy-transfer value of heavy ion is a constant of 98 MeV·cm2/mg in the whole incident track, and the other parameters are almost maintained at the same value. Thus this novel structure can be widely used in designing single event irradiation-hardened power MOSFETs.

    Full Text Available Abstract The compatibilization of recycled PP/PET blend with high and low concentration (20 and 5 phr of elastomer functionalized by maleic anhydride (SEBS-g-MA was achieved. Recycled polypropylene from plastic industry and recycled PET from post-consumer bottles was used. PP/PET blends: 80:20 w/w, 50:50 w/w and 20:80 w/w were prepared in an internal mixer for mechanical properties, thermal properties, morphology and rheological properties. SEBS-g-MA promoted compatibilization of the PP/PET blends and improved their properties. With an increasing compatibilization level, the refinement of morphology was observed in the PET rich blend. Compatibilized blends showed negative deviation in the PET glass transition temperature related to neat PET, demonstrating that compatibilization was very successful. PET crystallization was accelerated in the blends due to PP presence that enhanced nucleation. It was found that the 50/50/20 blend showed huge potential for textile fiber application and that of 80/20/20 showed more intermediary properties than neat polymers.

    Staphylococcal enterotoxin B (SEB) causes staphylococcal food poisoning and is produced in up to ten times higher quantities than other major enterotoxins. While Staphylococcus aureus growth is often repressed by competing flora, the organism exhibits a decisive growth advantage under some stress conditions. So far, data on the influence of food-related stressors and regulatory mutations on seb expression is limited and largely based on laboratory strains, which were later reported to harbor mutations. Therefore, the aim of this study was to investigate the influence of stress and regulatory mutations on seb promoter activity. To this end, transcriptional fusions were created in two strains, USA300 and HG003, carrying different seb upstream sequences fused to a blaZ reporter. NaCl, nitrite, and glucose stress led to significantly decreased seb promoter activity, while lactic acid stress resulted in significantly increased seb promoter activity. Loss of agr decreased seb promoter activity and loss of sigB increased promoter activity, with the magnitude of change depending on the strain. These results demonstrate that mild stress conditions encountered during food production and preservation can induce significant changes in seb promoter activity. Copyright © 2017 Elsevier Ltd.

    2015-11-01

    Full Text Available We propose a long-term parameterization scheme for two critical parameters, zero-plane displacement height (d and aerodynamic roughness length (z0m, that we further use in the Surface Energy Balance System (SEBS. A sensitivity analysis of SEBS indicated that these two parameters largely impact the estimated sensible heat and latent heat fluxes. First, we calibrated regression relationships between measured forest vertical parameters (Lorey’s height and the frontal area index (FAI and forest aboveground biomass (AGB. Next, we derived the interannual Lorey’s height and FAI values from our calibrated regression models and corresponding forest AGB dynamics that were converted from interannual carbon fluxes, as simulated from two incorporated ecological models and a 2009 forest basis map These dynamic forest vertical parameters, combined with refined eight-day Global LAnd Surface Satellite (GLASS LAI products, were applied to estimate the eight-day d, z0m, and, thus, the heat roughness length (z0h. The obtained d, z0m and z0h were then used as forcing for the SEBS model in order to simulate long-term forest evapotranspiration (ET from 2000 to 2012 within the Qilian Mountains (QMs. As compared with MODIS, MOD16 products at the eddy covariance (EC site, ET estimates from the SEBS agreed much better with EC measurements (R2 = 0.80 and RMSE = 0.21 mm·day−1.

    Full Text Available This study proposes a method for improving the estimation of surface turbulent fluxes in surface energy balance system (SEBS model under water stress conditions using MODIS data. The normalized difference water index (NDWI as an indicator of water stress is integrated into SEBS. To investigate the feasibility of the new approach, the desert-oasis region in the middle reaches of the Heihe River Basin (HRB is selected as the study area. The proposed model is calibrated with meteorological and flux data over 2008–2011 at the Yingke station and is verified with data from 16 stations of the Heihe Watershed Allied Telemetry Experimental Research (HiWATER project in 2012. The results show that soil moisture significantly affects evapotranspiration (ET under water stress conditions in the study area. Adding the NDWI in SEBS can significantly improve the estimations of surface turbulent fluxes in water-limited regions, especially for spare vegetation cover area. The daily ET maps generated by the new model also show improvements in drylands with low ET values. This study demonstrates that integrating the NDWI into SEBS as an indicator of water stress is an effective way to improve the assessment of the regional ET in semi-arid and arid regions.

    Full Text Available Staphylococcal enterotoxins (SEs are a major cause of food-borne diseases, most commonly SEs assayed immunologically with ELISA. An immunoassay based on fluorescein dye doped silica dioxide nanoparticles (F-SiNPs and magnetic bead (MB is described here for the detection of staphylococcal enterotoxin B (SEB. F-SiNPs have unique optical properties which make them attractive for biosensing. The water-in-oil (W/O reverse microemulsion method was used for the synthesis of F-SiNPs (~ 95 nm of diameter. The F-SiNPs were characterized using SEM, TEM and FTIR spectroscopy. The detection of SEB is preformed in PBS buffer, and bottled drinking water using sandwich immunoassay format. Target analytes were captured using MBs modified with the antigen-specific “capture” antibody, and detected using F-SiNP labeled secondary antigen-specific antibody. We report a limit of detection down to 1 ng/mL SEB spiked sample in less than 2 hr assay time using fluorocount method. This study demonstrates the bio warfare agent SEB capture by magnetic beads and detection using F-SiNPs.

    1991-01-01

    In this paper a study to determine the Single Event Burnout (SEB) sensitivity for burnout of IRF-150 Power MOSFETs in both static and dynamic modes in terms of LET threshold and cross section is described. The dynamic tests were conducted with a power converter which was designed for actual space application. The results were compared with static measurements which were made during the exposure to the heavy ions. The data showed that the dynamic mode was less sensitive than the static by two orders of magnitude in cross section. It was also observed that ions with a range less than 30 microns did not produce destructive burnout in the dynamic mode even when their LET exceeded the threshold value. The extent of physical MOSFET damage in the destructive, dynamic tests appeared to correlate with the ion LET and source-drain voltage

  12. Regional Estimation of Remotely Sensed Evapotranspiration Using the Surface Energy Balance-Advection (SEB-A Method

    Directory of Open Access Journals (Sweden)

    Suhua Liu

    2016-08-01

    Full Text Available Evapotranspiration (ET is an essential part of the hydrological cycle and accurately estimating it plays a crucial role in water resource management. Surface energy balance (SEB models are widely used to estimate regional ET with remote sensing. The presence of horizontal advection, however, perturbs the surface energy balance system and contributes to the uncertainty of energy influxes. Thus, it is vital to consider horizontal advection when applying SEB models to estimate ET. This study proposes an innovative and simplified approach, the surface energy balance-advection (SEB-A method, which is based on the energy balance theory and also takes into account the horizontal advection to determine ET by remote sensing. The SEB-A method considers that the actual ET consists of two parts: the local ET that is regulated by the energy balance system and the exotic ET that arises from horizontal advection. To evaluate the SEB-A method, it was applied to the middle region of the Heihe River in China. Instantaneous ET for three days were acquired and assessed with ET measurements from eddy covariance (EC systems. The results demonstrated that the ET estimates had a high accuracy, with a correlation coefficient (R2 of 0.713, a mean average error (MAE of 39.3 W/m2 and a root mean square error (RMSE of 54.6 W/m2 between the estimates and corresponding measurements. Percent error was calculated to more rigorously assess the accuracy of these estimates, and it ranged from 0% to 35%, with over 80% of the locations within a 20% error. To better understand the SEB-A method, the relationship between the ET estimates and land use types was analyzed, and the results indicated that the ET estimates had spatial distributions that correlated with vegetation patterns and could well demonstrate the ET differences caused by different land use types. The sensitivity analysis suggested that the SEB-A method requested accurate estimation of the available energy, R n − G

In this regard, the composites based on the blend and various amounts of nanoclay (1,3,5 wt% were melt compounded using an internal mixer at the temperature of 190°C, rotor speed of 75rpm for 12min. The prepared samples were compression molded in a hot-press machine under the conditions of 190°C, 31 MPa pressure for 9 min to obtain the sheets in various thicknesses. The sheets were then cooled to ambient temperature with cooling water at the rate of 1.5°C.s-1. X-ray diffraction (XRD and transmission electron microscopy (TEM were used to study the structure and morphology of the samples. In addition, the mechanical and thermal properties were determined by standard methods. The results of X-ray diffraction and transmission electron photographs confirmed both exfoliated and intercalated structures in the prepared samples. There were balanced strength/toughness properties in all the prepared nanocomposites by addition of both SEBS-g-MA and clay simultaneously. The measurement of rheological properties showed that as the shear rate increased, the apparent viscosity of the samples decreased (shear thinning behavior. Gradual increase in incorporation of nanoclay also decreased the melt flow index (MFI values. In addition, increases in nanoclay content had an insignificant effect on the thermal behavior and in that respect there were slight increases in degree of crystallinity, heat deflection temperature (HDT as well as Vicat softening point by slight increase in temperatureThe effect of nanoclay (Cloisite® 15A was studied in relation to the flow behavior, mechanical and thermal properties of polypropylene/maleic anhydride-g-(styrene-ethylene-butylene-styrene triblock copolymer (PP/SEBS(15%-g-MA blend.

    Damage to the inferior and fragile water and sanitation infrastructure of Haiti after Hurricane Matthew has created an urgent public health emergency in terms of likelihood of cholera occurring in the human population. Using satellite-derived data on precipitation, gridded air temperature, and hurricane path and with information on water and sanitation (WASH) infrastructure, we tracked changing environmental conditions conducive for growth of pathogenic vibrios. Based on these data, we predicted and validated the likelihood of cholera cases occurring past hurricane. The risk of cholera in the southwestern part of Haiti remained relatively high since November 2016 to the present. Findings of this study provide a contemporary process for monitoring ground conditions that can guide public health intervention to control cholera in human population by providing access to vaccines, safe WASH facilities. Assuming current social and behavioral patterns remain constant, it is recommended that WASH infrastructure should be improved and considered a priority especially before 2017 rainy season.

  16. Chimeric anti-staphylococcal enterotoxin B antibodies and lovastatin act synergistically to provide in vivo protection against lethal doses of SEB.

    Full Text Available Staphylococcal enterotoxin B (SEB is one of a family of toxins secreted by Staphylococcus aureus that act as superantigens, activating a large fraction of the T-cell population and inducing production of high levels of inflammatory cytokines that can cause toxic shock syndrome (TSS and death. Extracellular engagement of the TCR of T-cells and class II MHC of antigen presenting cells by SEB triggers the activation of many intracellular signaling processes. We engineered chimeric antibodies to block the extracellular engagement of cellular receptors by SEB and used a statin to inhibit intracellular signaling. Chimeric human-mouse antibodies directed against different neutralizing epitopes of SEB synergistically inhibited its activation of human T-cells in vitro. In the in vivo model of lethal toxic shock syndrome (TSS in HLA-DR3 transgenic mice, two of these antibodies conferred significant partial protection when administered individually, but offered complete protection in a synergistic manner when given together. Similarly, in vivo, lovastatin alone conferred only partial protection from TSS similar to single anti-SEB antibodies. However, used in combination with one chimeric neutralizing anti-SEB antibody, lovastatin provided complete protection against lethal TSS in HLA-DR3 transgenic mice. These experiments demonstrate that in vivo protection against lethal doses of SEB can be achieved by a statin of proven clinical safety and chimeric human-mouse antibodies, agents now widely used and known to be of low immunogenicity in human hosts.

    Full Text Available The effect of reprocessing two mixtures: recycled high impact polystyrene (HIPS with polybutadiene (PB; and HIPS with styrene-ethylene-butylenestyrene (SEBS have been studied in this article. Our results show that tensile strength increases, while the lengthening and viscosity decrease, as the number of reprocessing cycles increases. If we mix PB or SEBS with degraded HIPS, the mechanical properties of the virgin material are recovered and the rheological behavior maintains the viscosity values for the mixture with PB but these diminish notably for the mixture with SEBS.

  18. Social influence and the Matthew mechanism: The case of an artificial cultural market

    2014-10-01

    We show that the Matthew effect, or Matthew mechanism, was present in the artificial cultural market Music Lab in one-fourth of the “worlds” when social influence between individuals was allowed, whereas this effect was not present in the “world” that disallowed social influence between individuals. We also sketch on a class of social network models, derived from social influence theory, that may generate the Matthew effect. Thus, we propose a theoretical framework that may explain why the most popular songs could be much more popular, and the least popular songs could be much less popular, than when disallowing social influence between individuals.

  19. External cultic tradition and internal ethical purity in Matthew 15

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available In Matthew 15:1–20, Jesus responds to the accusation made by the Pharisees and the scribes that his disciples do not observe the tradition of hand-washing (οὐ γὰρ νίπτονται τὰς χεῖραςὅταν ἄρτον ἐσθίωσιν, because they do not wash their hands before they eat bread. In this story of dispute, two ideas are interwoven, namely the locus of impurity (external or internal and the manmade tradition of the elders (ἡ παράδοσις τῶν πρεσβυτέρων versus the Word of God (ὁ λόγος τοῦ Θεοῦ. The Pharisees are depicted as obsessed with external manmade rules to ensure purity, whilst Jesus is concerned with inner purity based on God’s Word. In this article, the story is interpreted on two levels. The first level describes the dispute between Jesus and the Pharisees. The second level explores the tension the Matthean community experienced in their encounter with Pharisean Judaism of their day – the Judaism of the dual Torah. The question is which aspect of the Torah is challenged by Matthew’s Jesus, and what he considers to be the true meaning of the Law. It seems that Matthew uses this story to define and maintain the identity and values of his community over and against that of the Pharisees and their successors. Devices that Matthew uses to define the identity and required morality for his community, are identified. Such devices demonstrate how a community’s values can influence the identity and ethics of a society. In Matteus 15:1–20 reageer Jesus op die aantyging van die Fariseërs en skrifgeleerdes dat sy dissipels nie die handewas-tradisie eerbiedig nie. In hierdie verhaal van dispuut word twee idees vervleg: eerstens dié van die locus van onreinheid, en tweedens dié van mensgemaakte tradisies teenoor die Woord van God. Die Fariseërs word voorgestel as mense wat obsessiefis oor mensgemaakte reëls wat reinheid verseker, terwyl Jesus op innerlike reinheid

    Full Text Available The continuing scaling down of complementary metal oxide semiconductor (CMOS has led researchers to build new devices with nano dimensions, whose behavior will be interpreted based on quantum mechanics. Single-electron devices (SEDs are promising candidates for future VLSI applications, due to their ultra small dimensions and lower power consumption. In most SED based digital logic designs, a single gate is introduced and its performance discussed. While in the SED based circuits the fan out of designed gate circuit should be considered and measured. In the other words, cascaded SED based designs must work properly so that the next stage(s should be driven by the previous stage. In this paper, previously NOT gate based on single electron box (SEB which is an important structure in SED technology, is reviewed in order to obtain correct operation in series connections. The correct operation of the NOT gate is investigated in a buffer circuit which uses two connected NOT gate in series. Then, for achieving better performance the designed buffer circuit is improved by the use of scaling process.

    The degree of safety that a structural component has against catastrophic fracture in service can be obtained from fracture mechanics parameters. The master curve could be used for integrity evaluation in pressure vessel of nuclear power plant. The pre-crack specimens are used in this evaluation. The tests based on ASTM E 8M and ASTM E 647 standards to determination of material properties related to fracture mechanics, most often performed in a servo-hydraulic drive equipment, are time consuming and costly. This paper presents the development of a system for nucleation and propagation of fatigue cracks on SE(B) specimens. The operating principle consists of a cyclic loading, concentrated in the center of the specimen, transmitted and controlled by an eccentric mechanism. The main contribution of this work is the low-cost technology in the production of fatigue pre-crack, and the possibility of performing the nucleation and propagation of the pre-crack required for obtaining the J{sub IC} and CTOD parameters. The experimental results satisfied expectations with respect to the plastic deformation in the crack tip and met the requirements of the standards. (author)

  4. Numerical investigation of 3-D constraint effects on brittle fracture in SE(B) and C(T) specimens

    International Nuclear Information System (INIS)

    Nevalainen, M.; Dodds, R.H. Jr.

    1996-07-01

    This investigation employs 3-D nonlinear finite element analyses to conduct an extensive parametric evaluation of crack front stress triaxiality for deep notch SE(B) and C(T) specimens and shallow notch SE(B) specimens, with and without side grooves. Crack front conditions are characterized in terms of J-Q trajectories and the constraint scaling model for cleavage fracture toughness proposed previously by Dodds and Anderson. The 3-D computational results imply that a significantly less strict size/deformation limit, relative to the limits indicated by previous plane-strain computations, is needed to maintain small-scale yielding conditions at fracture by a stress- controlled, cleavage mechanism in deep notch SE(B) and C(T) specimens. Additional new results made available from the 3-D analyses also include revised η-plastic factors for use in experimental studies to convert measured work quantities to thickness average and maximum (local) J-values over the crack front

  6. Regeneration and resurrection in Matthew – Peasants in campo hearing time signals from scribes

    Directory of Open Access Journals (Sweden)

    Andries G. van Aarde

    2011-10-01

    Full Text Available The article aimed to describe the distinctive element in the use of the motif of the resurrection in the Gospel of Matthew in comparison with Mark, Luke and the Sayings Gospel Q. It argued that the distinctive element occurs where parallel texts in Luke 22:24–30, Matthew 19:27–29 and Mark 10:28–31 converge. The distinctive element pertains particularly to the meaning of the Greek expression ‘en tē palingenesia’ in Matthew 19:28. By elaborating on time as a social construct, the article showed how Matthew deals with the conception of time differently than both Mark and Luke. It illustrated that the Gospel of Matthew represents a storyline consisting of a circular movement between ‘genesis’ (Mt 1:1 and ‘palingenesia’ (Mt 19:28, where the word ‘palingenesia’ denotes the meaning ‘regeneration’ rather than ‘resurrection’. Matthew does not narrate an abrupt transition from linear time to clock time. Both co-existed in a world where illiterate peasants and literate scribes scheduled their lives in terms of motifs pertaining to a linear and a punctual conception of time.

  7. Jesus as Healer in the Gospel of Matthew, Part II: Jesus as Healer in Matthew 8–9

    Directory of Open Access Journals (Sweden)

    Richard A. Culpepper

    2016-11-01

    Full Text Available This exploration of the healing narratives in Matthew 8 and 9, guided by current scholarship in the fields of medical anthropology and social-scientific study of ancient Mediterranean culture, shows that when viewed in their historical and cultural context these biblical narratives point us toward a more holistic understanding of healing that may encourage contemporary movements in this direction. In this context, the goal is ‘healing’ the person rather than simply ‘curing’ the disease. The goal of restoring persons to a state of well-being and social reintegration into their families and communities requires attention to the emotional, social and spiritual well-being of persons as well as their physical health. A critically and culturally informed interpretation of Matthew’s healing narratives may therefore promote the broader understanding of healing in view of these biblical stories.

  8. The Syriac versions of Old Testament quotations in Matthew

    2015-12-01

    Full Text Available In the Gospel of Matthew 10 quotations from the Old Testament are introduced by a formula containing the verb πληροῦν. This article explores the rendering of 9 of these 10 quotations in 3 Syriac versions of the New Testament, namely the Peshitta and the 2 versions of the Old Syriac Gospels (Sinaiticus and Curetonianus. The question addressed is the relationship of the Syriac versions to one another, to the Peshitta of the Old Testament and to the Greek Gospel. For the quotations in Matthew, their relationship to the Hebrew and Greek Old Testament is very important. In the quotations discussed, the Greek New Testament did not make much use of the Septuagint as it is known today. The Old Testament Peshitta influenced the Old Syriac, but not to the same extent in all instances. This influence could have been through Tatian’s Diatessaron. Tatian probably used the text of the Old Testament Peshitta for the quotations of the Old Testament in the gospels. In instances where the Curetonianus and the Sinaiticus differ, it could demonstrate attempts to bring the text closer to the Greek New Testament. The New Testament Peshitta normally started with a text close to the Old Syriac, but frequently adapted it to bring it closer to New Testament Greek.

  9. Cumulative (DisAdvantage and the Matthew Effect in Life-Course Analysis.

    Directory of Open Access Journals (Sweden)

    Miia Bask

    Full Text Available To foster a deeper understanding of the mechanisms behind inequality in society, it is crucial to work with well-defined concepts associated with such mechanisms. The aim of this paper is to define cumulative (disadvantage and the Matthew effect. We argue that cumulative (disadvantage is an intra-individual micro-level phenomenon, that the Matthew effect is an inter-individual macro-level phenomenon and that an appropriate measure of the Matthew effect focuses on the mechanism or dynamic process that generates inequality. The Matthew mechanism is, therefore, a better name for the phenomenon, where we provide a novel measure of the mechanism, including a proof-of-principle analysis using disposable personal income data. Finally, because socio-economic theory should be able to explain cumulative (disadvantage and the Matthew mechanism when they are detected in data, we discuss the types of models that may explain the phenomena. We argue that interactions-based models in the literature traditions of analytical sociology and statistical mechanics serve this purpose.

    2015-08-01

    Full Text Available One of the most intriguing aspects of the experience of reading the gospels, for both beginning students and those who have been at it for decades, is the growing awareness of how the gospels convey their message. Our attention is usually focused first on what the message is: the storyline, the plot, the climax or resolution, and its implications. As we continue to read and reread, we may find that we begin to grow interested in various features of the narrative, such as its organisation, collections of material (parables or miracle stories, repetitions, the ways characters are represented or the narrator’s comments. These are not incidental features of the gospel narrative. On the contrary, they are the elements with which it is constructed and that guide the reader’s experience of the narrative. In this article we will explore how Matthew leads its Jewish-Christian readers, sometime late in the 1st century and during theprocess of the separation of early believers from the synagogue, to accept Jesus’ teachings as a new teaching on righteousness and functionally at least a new Torah. Specifically, we will analyse the role of repetition and redundancy in Matthew’s narrative rhetoric in relation to this theme. Vervulling van die Skrif en Jesus se onderrig in Matteus.

    Predictive methodologies aimed at quantifying the impact of defects in oil and gas pipelines play a key role in safety assessment procedures of in-service facilities. Current methodologies for structural integrity assessments advocate the use of geometry dependent resistance curves so that crack-tip constraint in the test specimen closely matches the crack tip constraint for the structural component. Testing standards now under development to measure fracture resistance of pipeline steels (J and CTOD) most often employ single edge notched specimens under tension (SENT) to match a postulated defect in the structural component. This paper presents an investigation of the ductile tearing properties for a girth weld of an API 5L X80 pipeline steel using experimentally measured crack growth resistance curves (J-R curves). Testing of the girth weld pipeline steels employed side-grooved, clamped SE(T) specimen with center-crack weld and side-grooved, three-point bending SE(B) (or SENB) specimens to determine the J-R curves. The methods were compared in terms of geometry, relative crack size and crack-tip constraint, and the results were applied to a case study, to evaluate the degree of conservativeness in defect acceptance criteria. The tests involving SE(B) specimens are usually considered conservative, however, the comparison between this two methods may point an accurate alternative for girth weld assessments, since adequate geometry is adopted to describe accurately the structure's behavior.

    Full Text Available In this work, microencapsulated phase change materials (PCMs with a melting temperature of 28 ºC have been used to improve thermal inertia phenomena on an elastomeric matrix of styrene-ethylene/butylenes-styrene (SEBS material. The amount of PCMs has varied in the 1-10 wt. % and these materials have been processed by conventional injection molding without PCM degradation. Mechanical characterization of SEBS-PCM compounds has been carried out and the obtained results show good maintenance of both resistant and ductile properties for PCM amounts comprised in the 1-5 wt. % range. SEM analysis has revealed good interaction between PCM microcapsules and SEBS matrix which is a critical aspect to obtain good mechanical performance. The effect of PCM addition on thermal inertia has been evaluated by active infrared thermography, showing a remarkable effect on thermal regulation of SEBS in the temperature range close to the melting point of the PCM (28 ºC. This thermoregulation effect is more accurate as the PCM content increases. Also, cooling curves have been constructed in order to quantify the thermal inertia effect in a cooling process.

    2018-06-01

    Evapotranspiration (ET) estimation is of great importance due to its key role in water resource management. Surface energy modeling tools such as Surface Energy Balance Algorithm for Land (SEBAL), Mapping Evapotranspiration with Internalized Calibration (METRIC), and the Surface Energy Balance System (SEBS) can estimate the amount of evapotranspiration for every pixel of the satellite images. The main objective of this research is evaporation investigation from the freshwater bodies using SEBAL, METRIC, and SEBS. For this purpose, the Amirkabir dam reservoir and its nearby agricultural lands in a semi-arid climate were selected and studied from 2011 to 2017 as the study area. The implementations of this study were accomplished on 16 satellite images of Landsat TM5 and OLI. Then, SEBAL, METRIC, and SEBS were implemented on the selected images. Moreover, the corresponding pan evaporate measurements on the reservoir bank were considered as the ground truth data. Regarding to the results, SEBAL is not a reliable method to evaluate freshwater evaporation with the coefficient of determination (R2) of 0.36 and the Root Mean Square Error (RMSE) of 5.1 mm. On the other hand, METRIC with RMSE and R2 of 0.57 and 2.02 mm and SEBS with RMSE and R2 of 0.93 and 0.62 demonstrated a relatively good performance.

  4. Reconnoitering the effect of shallow groundwater on land surface temperature and surface energy balance using MODIS and SEBS

    Directory of Open Access Journals (Sweden)

    F. Alkhaier

    2012-07-01

    Full Text Available The possibility of observing shallow groundwater depth and areal extent using satellite measurements can support groundwater models and vast irrigation systems management. Moreover, these measurements can help to include the effect of shallow groundwater on surface energy balance within land surface models and climate studies, which broadens the methods that yield more reliable and informative results. To examine the capacity of MODIS in detecting the effect of shallow groundwater on land surface temperature and the surface energy balance in an area within Al-Balikh River basin in northern Syria, we studied the interrelationship between in-situ measured water table depths and land surface temperatures measured by MODIS. We, also, used the Surface Energy Balance System (SEBS to calculate surface energy fluxes, evaporative fraction and daily evaporation, and inspected their relationships with water table depths. We found out that the daytime temperature increased while the nighttime temperature decreased when the depth of the water table increased. And, when the water table depth increased, net radiation, latent and ground heat fluxes, evaporative fraction and daily evaporation decreased, while sensible heat flux increased. This concords with the findings of a companion paper (Alkhaier et al., 2012. The observed clear relationships were the result of meeting both conditions that were concluded in the companion paper, i.e. high potential evaporation and big contrast in day-night temperature. Moreover, the prevailing conditions in this study area helped SEBS to yield accurate estimates. Under bare soil conditions and under the prevailing weather conditions, we conclude that MODIS is suitable for detecting the effect of shallow groundwater because it has proper imaging times and adequate sensor accuracy; nevertheless, its coarse spatial resolution is disadvantageous.

    In a scale-free network, only a minority of nodes are connected very often, while the majority of nodes are connected rarely. However, what is the ratio of minority nodes to majority nodes resulting from the Matthew effect? In this paper, based on a simple preferential random model, the poor-rich demarcation points are found to vary in a limited range, and form a poor-rich demarcation interval that approximates to k/m in [3,4]. As a result, the (cumulative) degree distribution of a scale-free network can be divided into three intervals: the poor interval, the demarcation interval and the rich interval. The inequality of the degree distribution in each interval is measured. Finally, the Matthew effect is applied to the ABC analysis of project management. (general)

  7. Peter as character in the Gospel of Matthew: complexity and inversion

    2014-03-01

    Full Text Available This article focuses on the apostle Peter as a character in the Gospel of Matthew.  It aims at identifying the nuances and changes of the character Peter in the Gospel. For this purpose, I take as a starting point that the gospel belongs to the literary genre of ancient Greco-Roman Biography, which presents Jesus Christ as the protagonist. The other characters are developed in relationship with him. The same is true with the Apostle Peter. The article unfolds from narrative theory, in particular the categorization of characters. I categorize, based on Erich Auerbach and Robert Alter, the features of biblical characters, developing comparisons with theories of the character in the modern novel. The analysis of the main texts from the Gospel of Matthew that portray the character Peter leads to the conclusion that its main features are complexity and inversion. They produce an overview of the involution of the character in the narrative of the Gospel of Matthew.

  8. Language, meaning, sense and reference: Matthew's passion narrative and Psalm 22

    Directory of Open Access Journals (Sweden)

    S. van Tilborg

    1988-01-01

    Full Text Available The passion narrative of Jesus as told by Matthew is a verbal enunciation which finds its place next to other passion narratives in which the narrator lets the protagonist use the words of the '1' person of Psalm 22 and in which the narrator describes internal and external conflicts with the words of the Psalm. Against the background of the Greek Septuagint and the Aramaic text in the Targum, parallel to what the hymnist of Qumran tries to do and the narrator of the story about Aseneth, based on the narrative as we find it in Mark, Matthew took Psalm 22 as anchor for his story. What is described in the Psalm, happens in the life and death of Jesus. To approach Jesus' passion more closely, Matthew used poetic language: words on words on words. The passion and death of Jesus has thus become literature, an ambiguous attempt to express the impossible. The question, 'how can one maintain today compassion against the forces of violence?', is the concern of the article.

    This study reports on the integration of Artificial Neural Network (ANNs) with experimental data in predicting the solubility of carbon dioxide (CO2) blowing agent in SEBS by generating highest possible value for Regression coefficient (R2). Basically, foaming of thermoplastic elastomer with CO2 is highly affected by the CO2 solubility. The ability of ANN in predicting interpolated data of CO2 solubility was investigated by comparing training results via different method of network training. Regards to the final prediction result for CO2 solubility by ANN, the prediction trend (output generate) was corroborated with the experimental results. The obtained result of different method of training showed the trend of output generated by Gradient Descent with Momentum & Adaptive LR (traingdx) required longer training time and required more accurate input to produce better output with final Regression Value of 0.88. However, it goes vice versa with Levenberg-Marquardt (trainlm) technique as it produced better output in quick detention time with final Regression Value of 0.91.

    Full Text Available One of the most shocking Gothic novels was written by Matthew Gregory Lewis in 1796. His Gothic novel The Monk contains all the typical Gothic elements such as a ruined castle, aggressive villain, women in distress, the atmosphere of terror and horror and a lot more. This article analyses and compares to what extent the Gothic elements of the late 18th century survived in the contemporary detective story The Ice House (1993 written by Minette Walters and how these elements have changed.

  12. Comparative endurance testing of the Biomet Matthews Nail and the Dynamic Compression Screw, in simulated condylar and supracondylar femoral fractures

    2008-01-01

    Full Text Available Abstract Background The dynamic compression screw is a plate and screws implant used to treat fractures of the distal femur. The Biomet Matthews Nail is a new retrograde intramedullary nail designed as an alternative surgical option to treat these fractures. The objective of this study was to assess the comparative endurance of both devices. Method The dynamic compression screw (DCS and Biomet Matthews Nail (BMN were implanted into composite femurs, which were subsequently cyclically loaded using a materials testing machine. Simulated fractures were applied to each femur prior to the application of load. Either a Y type fracture or a transverse osteotomy was prepared on each composite femur using a jig to enable consistent positioning of cuts. Results The Biomet Matthews Nail demonstrated a greater endurance limit load over the dynamic compression screw in both fracture configurations. Conclusion The distal locking screws pass through the Biomet Matthews Nail in a unique "cruciate" orientation. This allows for greater purchase in the bone of the femoral condyle and potentially improves the stability of the fracture fixation. As these fractures are usually in weak osteoporotic bone, the Biomet Matthews Nail represents a favourable surgical option in these patients.

    Nature-based solutions, such as living shorelines, have the potential to restore critical ecosystems, enhance coastal sustainability, and increase resilience to natural disasters; however, their efficacy during storm events compared to traditional hardened shorelines is largely untested. This is a major impediment to their implementation and promotion to policy-makers and homeowners. To address this knowledge gap, we evaluated rock sill living shorelines as compared to natural marshes and hardened shorelines (i.e., bulkheads) in North Carolina, USA for changes in surface elevation, Spartina alterniflora stem density, and structural damage from 2015 to 2017, including before and after Hurricane Matthew (2016). Our results show that living shorelines exhibited better resistance to landward erosion during Hurricane Matthew than bulkheads and natural marshes. Additionally, living shorelines were more resilient than hardened shorelines, as they maintained landward elevation over the two-year study period without requiring any repair. Finally, rock sill living shorelines were able to enhance S. alterniflora stem densities over time when compared to natural marshes. Our results suggest that living shorelines have the potential to improve coastal resilience while supporting important coastal ecosystems. © 2018 by the Ecological Society of America.

    Matthew-Wood, Spear, PDAC or MCOPS9 syndrome are alternative names used to refer to combinations of microphthalmia/anophthalmia, malformative cardiac defects, pulmonary dysgenesis, and diaphragmatic hernia. Recently, mutations in STRA6, encoding a membrane receptor for vitamin A-bearing plasma retinol binding protein, have been identified in such patients. We performed STRA6 molecular analysis in three fetuses and one child diagnosed with Matthew-Wood syndrome and in three siblings where two adult living brothers are affected with combinations of clinical anophthalmia, tetralogy of Fallot, and mental retardation. Among these patients, six novel mutations were identified, bringing the current total of known STRA6 mutations to seventeen. We extensively reviewed clinical data pertaining to all twenty-one reported patients with STRA6 mutations (the seven of this report and fourteen described elsewhere) and discuss additional features that may be part of the syndrome. The clinical spectrum associated with STRA6 deficiency is even more variable than initially described. Copyright 2009 Wiley-Liss, Inc.

    Cardiac rehabilitation should safeguard that socioeconomic factors or other differences that affect people's cardiovascular health are not further aggravated after healthcare treatment. The study examines whether socioeconomic status, emotional problems, or the severity of disease affect people's ability to continue to work after heart disease. We also examined if these effects can be explained by differences in motivational factors. 217 patients (41 women) from the Krokeide Rehabilitation Centre in Bergen participated. Multiple linear regression analysis was used to examine motivational differences, and logistic regression analysis was used to examine whether socioeconomic factors or other differences affected people's ability to continue to work after heart disease. Self-efficacy for future work strongly impacted the likelihood of being incapacitated for work during the 2-year follow-up. The household's total income and emotional problems were statistically significant related to patients dropping out from work in the course of the observation. The association between emotional problems and future work was mediated by motivational problems. The relation between income and future incapacity for work could not be explained by motivational factors. The study shows a clear Matthew effect on people's ability to continue to work after heart disease as low-income groups and people with emotional problems are more at risk of dropping out of work. This Matthew effect was, however, only explained by the motivational difficulties for the association between emotional distress and dropping out of work and not for the impact of household income on the likelihood of leaving work.

    Great Exuma has been a UNESCO Eco-hydrology Project Site with a focus on coastal restoration and flood management. Great Exuma and its largest settlement, George Town, support a population of just over 8.000 people on an island dominated by extensive coastal wetlands. The Victoria Pond Eco-Hydrology project restored flow and drainage to highly-altered coastal wetlands to reduce flooding of the built environment as well as regain ecological function. The project was designed to show the value of a protected wetland and coastal environment within a populated settlement; demonstrating that people can live alongside mangroves and value "green" infrastructure for flood protection. The restoration project was initiated after severe storm flooding in 2007 with Tropical Storm Noel. In 2016, the passing of Hurricane Matthew had unprecedented impacts on the coastal communities of Great Exuma, challenging past practices in restoration and flood prevention. This talk reviews the loss of natural capital (for example, fish populations, mangroves, salt water inundation) from Hurricane Matthew based on a rapid response survey of Great Exuma. The surprisingly find was the impact of storm surge on low-lying areas used primarily for personal farms and small-scale agriculture. Although women made up the overwhelming majority of people who attended Coastal Restoration workshops, women were most adversely impacted by the recent hurricane flooding with the loss of their small low-lying farms and gardens. Although increasing culverts in mangrove creeks in two areas did reduce building flood damage, the low-lying areas adjacent to mangroves, mostly ephemeral freshwater wetlands, were inundated with saltwater, and seasonal crops in these areas were destroyed. These ephemeral wetlands were designed as part of the wetland flooding system, it was not known how important these small areas were to artisanal farming on Great Exuma.

    Full Text Available The Olivet Discourse is complex and difficult to interpret, but crucial to any preaching about eschatology. By identifying two chiastic structures that mirror each other, namely in Matthew 21:1−23:39 and 24:1−25:46, the relation and correspondence of the parts to each other and to the whole may be identified. Whereas the centre of the chiastic structure of Matthew 21:1−23:39 emphasises the authority and identity of Jesus Christ, the Lord and Son of David, the centre of the chiastic structure of 24:1−25:46 focuses on the sign and coming of the Son of Man. Matthew 21:1−25:46 could be a major literary unit that emphasises the King’s entrance into, rejection of and exit from the temple and Jerusalem during his first coming, juxtaposed with the sign and coming of the Son of Man to Jerusalem in glory. Until then, the Lord expects his followers to watch, to be ready and prepared as they labour faithfully for him in these last days. Kyk die heerlikheid van die Koning: Die chiastiese strukture van Matteus 21−25. Die Olyfberg-diskoers is kompleks en moeilik om te interpreteer, dog onontbeerlik vir enige prediking oor die eskatologie. Deur die eiening van twee chiastiese strukture wat mekaar weerspieël, naamlik in Matteus 21:1−23:39 en 24:1−25:46, kan die verhouding en ooreenkomste van die dele tot mekaar en die geheel geïdentifiseer word. Waar die middelpunt van die chiastiese struktuur in Matteus 21:1−23:39 die gesag en identiteit van Jesus Christus, die Here en Seun van Dawid, beklemtoon, fokus die middelpunt van die chiastiese struktuur in 24:1−25:46 op die teken en koms van die Seun van die Mens. Matteus 21:1−25:46 sou ’n belangrike literêre eenheid kon wees wat die Koning se ingang na, verwerping en agterlaat van die tempel en Jerusalem tydens sy eerste koms beklemtoon teenoor die teken en koms van die Seun van die Mens na Jerusalem in heerlikheid. Tot dan verwag die Here van sy volgelinge om te waak

    Full Text Available Track Changes, by Matthew Kirschenbaum, tells the early history of word processing, roughly situated between 1964—when the IBM Magnetic Tape/Selectric Typewriter (MT/ST was advertised as a word processing system for offices—and 1984—when the Apple Macintosh generalized the graphical user interface in personal computers. The history of word processing both as technological process and mode of textual production is deeply entangled with the changes in the technologies of writing as they reflect and contribute to efficiency and control in increasingly bureaucratic processes of social administration and organization. The literary history of word processing can be situated within this general computerization of the modes of production of writing. Kirschenbaum’s methods combine archival work in special collections and writers’ archives, oral interviews with writers and engineers, and hands-on descriptions of historical word processing machines. Track Changes is the subject of this interview.

  2. Jesus as healer in the Gospel of Matthew, part 1: Methodology

    Directory of Open Access Journals (Sweden)

    Richard A. Culpepper

    2016-11-01

    Full Text Available This exploration of the healing narratives in Matthew 8 and 9, guided by current scholarship in the fields of medical anthropology and social-scientific study of ancient Mediterranean culture, shows that when viewed in their historical and cultural context these biblical narratives point toward a more holistic understanding of healing that may encourage contemporary movements in this direction. In this context, the goal is ‘healing’ the person rather than simply ‘curing’ the disease. The goal of restoring persons to a state of well-being and social reintegration into their families and communities requires attention to the emotional, social, and spiritual well-being of persons as well as their physical health. A critically and culturally informed interpretation of Matthew’s healing narratives may therefore promote the broader understanding of healing in view in these biblical stories.

  3. From text to intertext: Intertextuality as a paradigm for reading Matthew

    Directory of Open Access Journals (Sweden)

    Stefan Alkier

    2005-10-01

    Full Text Available In this article intertextuality is introduced as one important part of a theory of the semiotics of biblical texts. Intertextuality is an essential factor for the generation of the meanings of a text in the acts of the production and reception of a text. It opens the internal structure of a text with regard to its relations to other texts. The semiotic concept of intertextuality distinguishes three ways of intertextual readings: production-oriented intertextuality, reception-oriented intertextuality and experimental intertextuality. This wide but differentiated concept of intertextuality can serve as a theory and helpful method for investigations of the history of biblical texts as well as for reflected school lessons, sermons and poetics in today’s times. An intertextual reading of the first chapter of Matthew provides a test case of this semiotic concept of intertextuality.

  4. Chrysostom’s exegesis of the Gospel according to St. Matthew

    2008-06-01

    Full Text Available This article is divided into four sections. In the first, Fr. Arkadiusz Baron describes shortly the reception of Chrysostom’s writings in the ancient world in the East and in the West. It is surprising that the “Golden Mouth” and his homilies have triggered so many difficulties from the very beginning until the present. In the past, in the East, a growing conflict with the Severian of Gabbala and other bishops became the main obstacle to the reception of Chrysostom’s preaching. In 403, at the so-called council at the oak, Chrysostom was condemned and exiled. One of many false accusations charged him with being too merciful toward sinners who were recidivists. In the West, Anian of Celedo, Pelagius’ friend, translated Chrysostom’s homilies (especially on Matthew into Latin. Pelagianism was condemned and Chrysostom was suspected to be semi-Pelagian. The oldest and most integral Latin version of Chrysostom’s homilies on record date back from the twelfth century. In the fifteenth century pope Nicholaus V asked for a new translation. Similarly in Poland, Chrysostom was not too lucky. In Polish, only about 15 per cent of his homilies are available. Among the translators are J. Wujek, A. Załęski and J. Krystyniacki from the eighteenth century, and T. Sinko, W. Kania, A. Baron and J. Iluk from the twentieth century. Some of them are historians and philologists, but not theologians. This is a problem of the existing Polish translations: we need a good theological, biblical and homiletical elaboration of Chrysostom’s homilies. Homilies on Matthew were preached in 390 in Antioch when Chrysostom was already well-known. Chrysostom’s homilies are the first and one of the best ancient commentaries to this Gospel. He is the only man who in the first millennium of Christianity explained the Acts of the Apostles, and he is the only one in Christianity to do this in the form of homilies.

In these spaces, not only do the masculine protagonists interact, but also several feminine characters do as well. The three female characters (Betty, Peggy and Joan, who will be analyzed, represent the female stereotypes of this period: the idyllic housewife, the Sandra Dee prototype and the bombshell Marilyn Monroe archetype. In comparing the private and public spaces of the home and the office, these women´s sexuality and submission will be affected and influenced by the spaces they inhabit.

    IntroductionHurricane Matthew moved adjacent to the coasts of Florida, Georgia, South Carolina, and North Carolina. The hurricane made landfall once near McClellanville, South Carolina, on October 8, 2016, as a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale. The U.S. Geological Survey (USGS) deployed a temporary monitoring network of storm-tide sensors at 284 sites along the Atlantic coast from Florida to North Carolina to record the timing, areal extent, and magnitude of hurricane storm tide and coastal flooding generated by Hurricane Matthew. Storm tide, as defined by the National Oceanic and Atmospheric Administration, is the water-level rise generated by a combination of storm surge and astronomical tide during a coastal storm.The deployment for Hurricane Matthew was the largest deployment of storm-tide sensors in USGS history and was completed as part of a coordinated Federal emergency response as outlined by the Stafford Act (Public Law 92–288, 42 U.S.C. 5121–5207) under a directed mission assignment by the Federal Emergency Management Agency. In total, 543 high-water marks (HWMs) also were collected after Hurricane Matthew, and this was the second largest HWM recovery effort in USGS history after Hurricane Sandy in 2012.During the hurricane, real-time water-level data collected at temporary rapid deployment gages (RDGs) and long-term USGS streamgage stations were relayed immediately for display on the USGS Flood Event Viewer (https://stn.wim.usgs.gov/FEV/#MatthewOctober2016). These data provided emergency managers and responders with critical information for tracking flood-effected areas and directing assistance to effected communities. Data collected from this hurricane can be used to calibrate and evaluate the performance of storm-tide models for maximum and incremental water level and flood extent, and the site-specific effects of storm tide on natural and anthropogenic features of the environment.

    Full Text Available The task of Jesus’ disciples might be to juxtapose ‘new and old’ unconditional prophecies of the kingdom of heaven. After describing its setting, the four parables in Matthew 13, presented in private, are considered from a pre-millennial perspective. The parable of the hidden treasure may indicate how Jesus Christ first authenticates and then hides his authority and power to rule as King in terms of the Davidic Covenant over the literal Davidic kingdom – before he then goes to the cross. Having been to the cross, the parable of the pearl merchant may show how the first, spiritual phase of the kingdom commences when Christ Jesus starts his pearl ministry as High Priest in terms of the New Covenant. The parable of the dragnet has in view the transition from the spiritual phase of the kingdom into its future phase. An overview of the four privately given parables of Matthew 13 is then provided. After this a summary of the new and old prophecies contained in the eight parables of Matthew 13 is presented, followed by the conclusion. ’n Ondersoek na Matteus 13 as ’n profetiese diskoers: Die vier gelykenisse wat privaat aangebied is. Die taak van Jesus se dissipels sou kon wees om ‘nuwe en ou’ onvoorwaardelike profesieë van die koninkryk van die hemele met mekaar te vergelyk. Nadat die konteks beskryf is, word die vier gelykenisse in Matteus 13 wat privaat aangebied is vanuit ’n pre-millenniale perspektief oorweeg. Die gelykenis van die verborge skat sou kon aantoon hoe Jesus Christus sy gesag en mag om as Koning in terme van die Dawidiese Verbond oor die letterlike Dawidiese koninkryk te regeer, eers bevestig en dan verberg – waarna Hy kruis toe gaan. Nadat Hy gekruisig is, sou die gelykenis van die pêrelkoper kon aantoon hoe die eerste, geestelike fase van die koninkryk ’n aanvang neem as Christus Jesus sy pêrelbediening as Hoëpriester in terme van die Nuwe Verbond begin.

    Full Text Available In “The Order,” Matthew Barney transforms the Guggenheim Museum into a space reminding of a computer game or sports-arena. The protagonist struggles his way through different ‘levels’ and at the heart of the setting, he is confronted with the para-athlete Aimee Mullins, a cyborg embodying the Deleuzian notion of the ani/omalous. To complete his final task, the protagonist kills the creature. The question arises, why the ani/omalous has to be violently eliminated. In this respect, it is important to know that the DVD offers two viewing options: a film version structured according to a fixed narrative order and an interactive version where one can switch between the levels simultaneously. Thus, Barney’s film also raises the question of the aesthetic order at work and invites to consider how what is shown relates to the way in which it is shown.Keywords: Matthew Barney, becoming ani/omalous, Deleuze & Guattari, violence in artMatthew Barney’s hybrid monumental aesthetic work the Cremaster Cycle, consisting of film material, but also integrating drawings, sculpture, photography and performance elements can as such be considered as a multiplicity in Gilles Deleuze’s and Félix Guattari’s terms. In A Thousand Plateaus, Deleuze and Guattari argue against Art (with a capital A as a nominal concept and in favour of “the possibility of a simultaneous usage of the various arts within a determinable multiplicity” (331. That Barney’s work is indebted to Deleuze’s and Guattari’s philosophy seems unquestionable. What interests me in this paper is the relation between Deleuze’s and Guattari’s thinking and Barney’s own theoretical conceptions of art as well as how an example of Barney’s artistic work locates itself against the background of these frameworks. To do so, I want to concentrate on a so-called “choric interlude” in Cremaster 3 titled “The Order,” “which rehearses the initiation rites of the Masonic

    2014-10-01

    Full Text Available The Matthean redaction of Mark 7:30 in Matthew 15:28 often receives scant attention in scholarship in terms of its narrative quality. At most, it is regarded as a truncation of the full Marcan version, while all attention is given to Matthew’s introduction of the notion of ‘faith’ in this verse. This article argues, by contrast, and on the basis of a synoptic comparison and narratological analysis of both texts, that more justice is done to both versions of the conclusion of this healing miracle when understanding them as achieving different narrative effects, with Matthew focusing on the immediacy of the healing, while Mark creates suspense, thus focusing on the veracity of Jesus’ statement that the girl in question is healed.

  11. Is Matthew 28:16–20 the summary of the Gospel?

    2014-11-01

    Full Text Available It is generally acknowledged that the Great Commission at the end of Matthew’s Gospel is a dramatic and fitting end to the evangelist’s narrative. In the eyes of many scholars this final pericope does more than simply conclude the Gospel; it serves as a summary of the text’s major themes and even provides the interpretative key by which the earlier story should be read. This view, however, is questionable for two reasons. Firstly, the Great Commission introduces new themes and motifs into the Gospel story, which means that it cannot be viewed as a mere summary of what has come before. Secondly, this passage does not mention all the major themes of the Gospel. While some important motifs are included in the final pericope, there are others that receive no mention at all. This point too casts considerable doubt on the view that Matthew 28:16–20 serves to summarise Matthew’s story of Jesus. Moreover, the Great Commission, despite recalling a number of earlier themes, looks more towards the time of the future Church than back to the time of ‘the historical Jesus’. It is therefore better viewed as a bridging text that concludes one Christian story about the mission of Jesus and introduces another story about the history of the Church.

    Full Text Available Gary Gilmore, a murderer who was condamned to death in the USA in 1976, gained international notoriety thanks to his decision to accept and encourage his death sentence, refusing every kind of juridical appeal, surprisingly turning his own execution into a public and intentional suicide. For its power to make American institutions wonder about ethical and political problems, like the legitimacy of death penalty or the relationship between individual freedom and public law, this case inspired in 1979 The Executioner's Song, a non-fiction novel by Norman Mailer. about twenty years later Gilmore became a character of The Cremaster Cycle, one of the most important works by the american video-artist Matthew Barney, who based the plot of his Cremaster 2 (the second episode of this five-movie saga on Mailer's novel. The comparison between Cremaster 2 and its literary model will provide an example of the transformation of a story between different artistic languages, but also between different historical and cultural backgrounds: in the post human era the story of Gary Gilmore has lost most of its political and ethical meanings becoming a symbol of the struggle between human willingness and biological destiny.

  13. Leveraging Twitter to gauge evacuation compliance: Spatiotemporal analysis of Hurricane Matthew.

    2017-01-01

    Hurricane Matthew was the deadliest Atlantic storm since Katrina in 2005 and prompted one of the largest recent hurricane evacuations along the Southeastern coast of the United States. The storm and its projected landfall triggered a massive social media reaction. Using Twitter data, this paper examines the spatiotemporal variability in social media response and develops a novel approach to leverage geotagged tweets to assess the evacuation responses of residents. The approach involves the retrieval of tweets from the Twitter Stream, the creation and filtering of different datasets, and the statistical and spatial processing and treatment to extract, plot and map the results. As expected, peak Twitter response was reached during the pre-impact and preparedness phase, and decreased abruptly after the passage of the storm. A comparison between two time periods-pre-evacuation (October 2th-4th) and post-evacuation (October 7th-9th)-indicates that 54% of Twitter users moved away from the coast to a safer location, with observed differences by state on the timing of the evacuation. A specific sub-state analysis of South Carolina illustrated overall compliance with evacuation orders and detailed information on the timing of departure from the coast as well as the destination location. These findings advance the use of big data and citizen-as-sensor approaches for public safety issues, providing an effective and near real-time alternative for measuring compliance with evacuation orders.

    2007-06-01

    Full Text Available The paper deals with the multilayered elegy “Westminster Abbey;” which was not given a lot of attention by Matthew Arnold’s critics. The poem is dedicated to Arnold’s life-long friend Dean Stanley; who was; like Arnold himself; “a child of light.” The term refers to their common fight against Philistinism in the English society of the time. As the poem is about a real person; it contains real data; such as excerpts from Stanley’s life; described in the form of praise. However; the poem also introduces the old Saxon legend of consecration of the Abbey; namely the consecration by the light; performed by the First Apostle (St Peter himself. In addition to the legend; Arnold also used some classical Greek allusions to depict the late Dean’s character. In one of the allusions; Stanley is associated with Demophon; whose immortality was never achieved due to the fault of another human; and in the second he is transformed into an everlasting oracle of the Abbey using the Trophonius; a builder of Delphi; metaphor. All elements of the poem form a homogenous eulogy; making it worthwhile reading for English scholars and students; and possibly a candidate for the English poetic canon.

    Energy transfer in the photosynthetic Fenna-Matthews-Olson (FMO) complex of the Green Sulfur Bacteria is studied theoretically taking all three subunits (monomers) of the FMO trimer and the recently found eighth bacteriochlorophyll (BChl) molecule into account. For the calculations we use the efficient Non-Markovian Quantum State diffusion approach. Since it is believed that the eighth BChl is located near the main light harvesting antenna we look at the differences in transfer between the situation when BChl 8 is initially excited and the usually considered case when BChl 1 or 6 is initially excited. We find strong differences in the transfer dynamics, both qualitatively and quantitatively. When the excited state dynamics is initialized at site eight of the FMO complex, we see a slow exponential-like decay of the excitation. This is in contrast to the oscillations and a relatively fast transfer that occurs when only seven sites or initialization at sites 1 and 6 is considered. Additionally we show that differences in the values of the electronic transition energies found in the literature lead to a large difference in the transfer dynamics.

    Electronic coherence has been shown to persist in the Fenna-Matthews-Olson (FMO) antenna complex from green sulfur bacteria at 77 K for at least 660 fs, several times longer than the typical lifetime of a coherence in a dynamic environment at this temperature. Such long-lived coherence was proposed to improve energy transfer efficiency in photosynthetic systems by allowing an excitation to follow a quantum random walk as it approaches the reaction centre. Here we present a model for bath-induced electronic transitions, demonstrating that the protein matrix protects coherences by globally correlating fluctuations in transition energies. We also quantify the dephasing rates for two particular electronic coherences in the FMO complex at 77 K using two-dimensional Fourier transform electronic spectroscopy and find that the lifetimes of individual coherences are distinct. Within the framework of noise-assisted transport, this result suggests that the FMO complex has been locally tuned by natural selection to optimize transfer efficiency by exploiting quantum coherence.

    We study theoretically the bio-sensing capabilities of metal nanowire surface plasmons. As a specific example, we couple the nanowire to specific sites (bacteriochlorophyll) of the Fenna-Matthews-Olson (FMO) photosynthetic pigment protein complex. In this hybrid system, we find that when certain sites of the FMO complex are subject to either the suppression of inter-site transitions or are entirely disconnected from the complex, the resulting variations in the excitation transfer rates through the complex can be monitored through the corresponding changes in the scattering spectra of the incident nanowire surface plasmons. We also find that these changes can be further enhanced by changing the ratio of plasmon-site couplings. The change of the Fano lineshape in the scattering spectra further reveals that “site 5” in the FMO complex plays a distinct role from other sites. Our results provide a feasible way, using single photons, to detect mutation-induced, or bleaching-induced, local defects or modifications of the FMO complex, and allows access to both the local and global properties of the excitation transfer in such systems.

    Pigment-protein complexes (PPCs) play a central role in facilitating excitation energy transfer (EET) from light-harvesting antenna complexes to reaction centres in photosynthetic systems; understanding molecular organisation in these biological networks is key to developing better artificial light-harvesting systems. In this article, we combine quantum-mechanical simulations and a network-based picture of transport to investigate how chromophore organization and protein environment in PPCs impacts on EET efficiency and robustness. In a prototypical PPC model, the Fenna-Matthews-Olson (FMO) complex, we consider the impact on EET efficiency of both disrupting the chromophore network and changing the influence of (local and global) environmental dephasing. Surprisingly, we find a large degree of resilience to changes in both chromophore network and protein environmental dephasing, the extent of which is greater than previously observed; for example, FMO maintains EET when 50% of the constituent chromophores are removed, or when environmental dephasing fluctuations vary over two orders-of-magnitude relative to the in vivo system. We also highlight the fact that the influence of local dephasing can be strongly dependent on the characteristics of the EET network and the initial excitation; for example, initial excitations resulting in rapid coherent decay are generally insensitive to the environment, whereas the incoherent population decay observed following excitation at weakly coupled chromophores demonstrates a more pronounced dependence on dephasing rate as a result of the greater possibility of local exciton trapping. Finally, we show that the FMO electronic Hamiltonian is not particularly optimised for EET; instead, it is just one of many possible chromophore organisations which demonstrate a good level of EET transport efficiency following excitation at different chromophores. Overall, these robustness and efficiency characteristics are attributed to the highly

    Computational models of cholera transmission can provide objective insights into the course of an ongoing epidemic and aid decision making on allocation of health care resources. However, models are typically designed, calibrated and interpreted post-hoc. Here, we report the efforts of a team from academia, field research and humanitarian organizations to model in near real-time the Haitian cholera outbreak after Hurricane Matthew in October 2016, to assess risk and to quantitatively estimate the efficacy of a then ongoing vaccination campaign. A rainfall-driven, spatially-explicit meta-community model of cholera transmission was coupled to a data assimilation scheme for computing short-term projections of the epidemic in near real-time. The model was used to forecast cholera incidence for the months after the passage of the hurricane (October-December 2016) and to predict the impact of a planned oral cholera vaccination campaign. Our first projection, from October 29 to December 31, predicted the highest incidence in the departments of Grande Anse and Sud, accounting for about 45% of the total cases in Haiti. The projection included a second peak in cholera incidence in early December largely driven by heavy rainfall forecasts, confirming the urgency for rapid intervention. A second projection (from November 12 to December 31) used updated rainfall forecasts to estimate that 835 cases would be averted by vaccinations in Grande Anse (90% Prediction Interval [PI] 476-1284) and 995 in Sud (90% PI 508-2043). The experience gained by this modeling effort shows that state-of-the-art computational modeling and data-assimilation methods can produce informative near real-time projections of cholera incidence. Collaboration among modelers and field epidemiologists is indispensable to gain fast access to field data and to translate model results into operational recommendations for emergency management during an outbreak. Future efforts should thus draw together multi

    While environmental research addresses scientific questions of possible societal relevance, it is unclear to what degree research focuses on environmental chemicals in need of documentation for risk assessment purposes. In a bibliometric analysis, we used SciFinder to extract Chemical Abstract Service (CAS) numbers for chemicals addressed by publications in the 78 major environmental science journals during 2000-2009. The Web of Science was used to conduct title searches to determine long-term trends for prominent substances and substances considered in need of research attention. The 119,636 journal articles found had 760,056 CAS number links during 2000-2009. The top-20 environmental chemicals consisted of metals, (chlorinated) biphenyls, polyaromatic hydrocarbons, benzene, and ethanol and contributed 12% toward the total number of links- Each of the top-20 substances was covered by 2,000-10,000 articles during the decade. The numbers for the 10-year period were similar to the total numbers of pre-2000 articles on the same chemicals. However, substances considered a high priority from a regulatory viewpoint, due to lack of documentation, showed very low publication rates. The persistence in the scientific literature of the top-20 chemicals was only weakly related to their publication in journals with a high impact factor, but some substances achieved high citation rates. The persistence of some environmental chemicals in the scientific literature may be due to a 'Matthew' principle of maintaining prominence for the very reason of having been well researched. Such bias detracts from the societal needs for documentation on less well known environmental hazards, and it may also impact negatively on the potentials for innovation and discovery in research.

  7. CMV latent infection improves CD8+ T response to SEB due to expansion of polyfunctional CD57+ cells in young individuals.

    Alejandra Pera

    Full Text Available Cytomegalovirus (CMV latent infection has a deleterious effect on the efficacy of influenza vaccination in the elderly, suggesting that CMV restricts immunological diversity impairing the immune system functionality in old age. Polyfunctional T cells produce multiple cytokines and higher amounts than mono-functional T cells. High number of polyfunctional T cells correlates with better prognosis during infection. Thus, the efficiency of T cell response associates with quality (polyfunctionality rather than with quantity (percentage of T cells. We analyze the effect of CMV infection on CD8+ T cells polyfunctionality --degranulation (CD107a, IFN-gamma and TNF-alpha production--, from young CMV-seropositive and CMV-seronegative individuals and in middle age CMV-seropositive donors, in response to Staphylococcal Enterotoxin B (SEB. Our results show a higher percentage of polyfunctional CD8+ T cells in young CMV-seropositive individuals compared to CMV-seronegative. Also, we find an expansion of CD8+CD57+ T cells in CMV-seropositive individuals, which are more polyfunctional than CD8+CD57- cells. In middle age individuals there is a higher frequency of SEB-responding CD8+ T cells, mainly TNF-alpha or TNF-alpha/IFN-gamma producers, whereas the percentage of polyfunctional cells (IFN-gamma/TNF-alpha/CD107a is similar to the percentages found in young CMV-seropositive. Therefore, whereas it has been shown that CMV latent infection can be detrimental for immune response in old individuals, our results indicate that CMV-seropositivity is associated to higher levels of polyfunctional CD8+ T cells in young and middle age donors. This increase in polyfunctionality, which can provide an immunological advantage in the response to other pathogens, is due to a CD8+CD57+ T cell expansion in CMV-seropositive individuals and it is independent of age. Conversely, age could contribute to the inflammation found in old individuals by increasing the percentage of cells

  8. The Matthew Effect and widely prescribed pharmaceuticals lacking environmental monitoring: case study of an exposure-assessment vulnerability.

    2014-01-01

    Assessing ambient exposure to chemical stressors often begins with time-consuming and costly monitoring studies to establish environmental occurrence. Both human and ecological toxicology are currently challenged by the unknowns surrounding low-dose exposure/effects, compounded by the reality that exposure undoubtedly involves mixtures of multiple stressors whose identities and levels can vary over time. Long absent from the assessment process, however, is whether the full scope of the identities of the stressors is sufficiently known. The Matthew Effect (a psychosocial phenomenon sometimes informally called the "bandwagon effect" or "iceberg effect," among others) may adversely bias or corrupt the exposure assessment process. The Matthew Effect is evidenced by decisions that base the selection of stressors to target in environmental monitoring surveys on whether they have been identified in prior studies, rather than considering the possibility that additional, but previously unreported, stressors might also play important roles in an exposure scenario. The possibility that the Matthew Effect might influence the scope of environmental stressor research is explored for the first time in a comprehensive case study that examines the preponderance of "absence of data" (in contrast to positive data and "data of absence") for the environmental occurrence of a very large class of potential chemical stressors associated with ubiquitous consumer use - active pharmaceutical ingredients (APIs). Comprehensive examination of the published data for an array of several hundred of the most frequently used drugs for whether their APIs are environmental contaminants provides a prototype example to catalyze discussion among the many disciplines involved with assessing risk. The findings could help guide the selection of those APIs that might merit targeting for environmental monitoring (based on the absence of data for environmental occurrence) as well as the prescribing of those

    Increased frequency and intensity of storm events such as tropical cyclones will have a major impact on estuarine and coastal biogeochemical cycling. Here, we determined the sources of dissolved and particulate organic matter (DOM and POM) as part of a larger study to quantify the short-term (several months) response of carbon and nitrogen cycling in the Neuse River Estuary-Pamlico Sound (NRE-PS) ecosystem to floodwaters associated with Hurricane Matthew. Sampling was conducted weekly in both the NRE-PS (October 2016 to January 2017), the Neuse River (NR) (October to December 2016) and in freshwater wetlands of the Neuse River above head of tide in March 2017. Specific ultraviolet (UV) absorbance at 254 nm (SUVA254) and stable carbon isotope ratios (δ13C-DOC) were used to determine the sources of DOM and POM transported to the NRE-PS in post-hurricane floodwaters. For DOM, SUVA254 values increased from 3.23 ±0.52 mg C L-1 m-1 in the NR to 4.14±0.52 mg C L-1 m-1 in the NRE and then declined to 3.63±0.32 mg C L-1 m-1 in PS. Combined with depleted δ13C-DOC values (-26 to -32‰) and elevated C:N values in the estuary and sound, these results confirm continued loading of fresh terrestrial organic matter into NRE-PS weeks after the storm. For POM, δ13C-POC and C:N ratio results likewise indicated a terrestrial source in floodwaters. SUVA254 values >3.5 mg C L-1 m-1 coupled with the depleted δ13C values and large C:N values were consistent with DOM primarily sourced from wetlands (e.g., wetland SUVA254 = 3.77±0.52 mg C L-1 m-1 in March 2017). We hypothesize that floodwaters connected riverine wetlands to the main channel of the NR, exporting DOM and POM into the NRE-PS. Our results indicate that upstream wetlands play a central and potentially significant role in organic matter enrichment and metabolism of estuarine and coastal waters, in light of increasing frequencies and intensities of tropical cyclones impacting coastal watersheds.

    Full Text Available This paper examined whether the modified Ritchie-Knott-Rice (RKR failure criterion can be applied to examine the feasibility of miniaturized Charpy type SE(B specimens of thickness-to-width ratio B/W=1. The modified RKR failure criterion considered in this paper is the (4δt,σ22c criterion which predicts the onset of cleavage fracture when the midplane crack-opening stress measured at a distance equal to four times the crack-tip opening displacement, denoted as σ22d, exceeds a critical stress σ22c. Specimens with B values of 25, 10, 3, and 2 mm (denoted as 25t, 10t, 3t, and 2t specimens, resp. manufactured with 0.55% carbon steel were tested at 20°C. The results showed that the modified RKR criterion could appropriately predict the occurrence of cleavage fracture accompanied by negligibly small stable crack extension (denoted as KJc fracture naturally for the 25t and 10t specimens. The modified RKR criterion could also predict that KJc fracture does not occur for the 2t specimen. The σ22c obtained from specimens for the 25t and 10t specimens exhibited only a small difference, indicating that the Jc obtained from the 10t specimens can be used to predict the Jc that will be obtained with the 25t specimens.

    has an urgent need for highly educated specialists, higher education has become an emerging industry driving national economic growth. In response to the current situation, Germany has begun making fundamental reforms to its system of higher education. Universities in modern Germany have long subscribed to the ideal of Humboldtian homogeneity. However, in recent years the German government has implemented various measures designed to increase competition, based on the principle that the lion’s share of educational resources should be devoted to those with the most distinguished, the so-called Matthew effect. Framing the current state of higher education in Germany as a showdown between Humboldt and Matthew, in this paper I use document analysis to present the traditional ideal of homogeneity, discuss the measures recently adopted for increasing competition, and to investigate how much influence these measures have had on distinguished students and researchers. Traditionally as the hallmark of the Germany higher education, the Humboldtian model has come into being by the following factors: the legal structure, the regulations preventing the hiring of former students as teaching staff, the non-competitive allocations of funding in higher education, and the way in which the higher education system developed. However, due to such recent measures as the Excellence Initiative, performance-based budget allocations, and the ranking of universities, in recent years German universities have begun to emphasize the importance of differentiation and specialization, while homogeneity has begun to fall by the wayside. While some may see these changes as an actual paradigm shift, due to the continuing influence of the traditional system, as well as the limited effect of the differentiation measures, it is unlikely that the German system of higher education will become as hierarchically structured as ivy-league universities in the United States; instead, it’s more likely that

    Full Text Available The aim of this work was to organize the first proficiency test (PT dedicated to staphylococcal enterotoxin B (SEB detection in milk and buffer solutions. This paper describes the organization of the PT trial according to EN ISO 17043 requirements. Characterization of the SEB stock solution was performed using SDS-PAGE and SE-specific ELISA, and amino acid analysis was used to assign its protein concentration. The solution was then used to prepare six PT materials (four milk and two buffer batches at a ng/g toxin level, which included one blank and one SEA-containing milk as specificity control. Suitable material homogeneity and stability were assessed using screening and quantitative ELISAs. Among the methods used by the participants, ELISA-based methods demonstrated their efficiency for the detection of SEB in both simple and complex matrices. The results serve as a basis for further improving the detection capabilities in expert laboratories and can therefore be considered as a contribution to biopreparedness.

    Full Text Available In this article, a chiastic structure in Matthew 17:14–20:34 is identified, evaluated and discussed. This structure highlights the movements of Jesus between the Mount of Transfiguration and Jerusalem as he is on his way to the cross to provide forgiveness of sins. However, this chiastic structure may also be considered in its wider, prophetic context. The structure of Matthew 17:14–20:34 fits into the larger thought or movement of Matthew 16:28–25:46. This shows Jesus’ movements from the Mount of Transfiguration to Jerusalem and beyond — not only during his first advent, but also at his second coming.

    Full Text Available The article scientifically substantiates the value of the mass in the history of musical art. Genesis of the mass and its development as a leading spiritual vocal and choral genre of the European middle Ages and Renaissance are considered. The peculiarities of composition and musical language of the oratorio «St. Matthew Passion» by Metropolitan Hilarion are identified. It is proved that the formation of the logic of melodic development, composition and harmonic solutions of the oratorio has been influenced by the traditions of Western music. Factors here are the images, themes, and artistic techniques, which are taken from the Byzantine and Russian Church services. Analysis of music of Pavel Lungin's “The Conductor” has revealed the importance of the oratorio “St. Matthew Passion” by Metropolitan Hilarion to understand the meaning of the work. The interaction of the visual and auditory aspects leads to a polyphony of meanings. This polyphony enriches the understanding of works of art.

  16. Influence of SEBS-MA and SBS compatibilizers on properties and morphology of blends of polystyrene/rubber residue (SBRr from the footwear industry

    Directory of Open Access Journals (Sweden)

    Carlos Bruno Barreto Luna

    Full Text Available Abstract The reuse of rubber waste is very important today, both to reduce the harmful effects on the environment, and to reduce the cost of new material development. Considering that most of the studies reported in literature refer to the reuse of tire waste, this article aims to evaluate the influence of styrene-butadiene-styrene (SBS and styrene-(ethylene-butylene-styrene grafted with maleic anhydride (SEBS-MA compatibilizers on the blend performance of polystyrene (PS/styrene-butadiene rubber residue (SBRr, which come from the footwear industry. The blends were prepared in a co-rotating twin screw extruder and then were molded by injection. They were analyzed by impact and tensile tests, heat deflection temperature (HDT, ductile-brittle transition temperature, dynamic mechanical thermal analysis (DMTA and transmission electron microscopy (TEM. The results evidenced that the use of any of the compatibilizers on the PS/SBRr blend significantly increased the impact strength, while the tensile properties and HDT were lower when compared to the polymer matrix. The ductile-brittle transition temperature remains at approximately 25°C range for all the blends. In general, it has been proved that the SBS was the most effective compatibilization process in the PS/SBRr system. The DMTA test shows the presence of two distinct temperature peaks. The morphologies obtained by TEM of binary and ternary blends were quite different and typical of immiscible blend. The results show a good perspective regarding the use of industrial waste (SBRr, since it may enhance a material that would be discarded.

  17. Examining the effects of hurricanes Matthew and Irma on water quality in the intracoastal waterway, St. Augustine, FL.

    The last several years have been marked by a high incidence of Atlantic tropical cyclones making landfall as powerful hurricanes or tropical storms. For example, in 2016 Hurricane Matthew devastated parts of the Caribbean and the southeastern United States. In 2017, this region was further battered by hurricanes Irma and Maria. Here, we present water quality data collected in the intracoastal waterway near the Whitney Lab for Marine Bioscience during hurricanes Matthew and Irma, a region that experienced flooding during both storms. YSI Exo 2 sondes were deployed to measure pH, salinity, temperature, dissolved O2, fluorescent dissolved organic matter (fDOM), turbidity, and Chlorophyll-a (Chl-a) on a 15 minute interval. The Hurricane Matthew sonde deployment failed as soon as the storm hit, but revealed an interesting phenomenon leading up to the storm that was also observed during Irma. Salinity in the intracoastal waterway (off the Whitney Lab dock) typically varies from purely marine to 15-20 psu throughout the tidal cycle. However, several days before both storms approached the Florida coast (i.e. when they were near the Caribbean), the salinity signal became purely marine, overriding any tidal signal. Anecdotally, storm drains were already filled up to street level prior to the storm hitting, poising the region for immense flooding and storm surge. The opposite effect was observed after Irma moved past FL. Water became much fresher than normal for several days and it took almost a week to return to "normal" salinity tidal cycles. As both storms hit, turbidity increased by an order of magnitude for a several hour period. fDOM and O2 behaved similar to salinity during and after Irma, showing a mostly marine signal (e.g. higher O2, lower fDOM) in the lead up, and brief switch to more freshwater influence the week after the storm. Chl-a peaked several days after the storm, presumably due to mobilization of nutrient rich flood and waste waters and subsequent algae

    The passage of Hurricane Matthew through central and eastern North Carolina during October 7–9, 2016, brought heavy rainfall, which resulted in major flooding. More than 15 inches of rain was recorded in some areas. More than 600 roads were closed, including Interstates 95 and 40, and nearly 99,000 structures were affected by floodwaters. Immediately following the flooding, the U.S. Geological Survey documented 267 high-water marks, of which 254 were surveyed. North Carolina Emergency Management documented and surveyed 353 high-water marks. Using a subset of these highwater marks, six flood-inundation maps were created for hard-hit communities. Digital datasets of the inundation areas, study reach boundary, and water-depth rasters are available for download. In addition, peak gage-height data, peak streamflow data, and annual exceedance probabilities (in percent) were determined for 24 U.S. Geological Survey streamgages located near the heavily flooded communities.

  1. St. Matthew Island reindeer crash revisited: Their demise was not nigh—but then, why did they die?

    Full Text Available Twenty-nine yearling reindeer (Rangifer tarandus were released on St. Matthew Island in the Bering Sea Wildlife Refuge in 1944: 24 females and five males. They were reported to have increased to 1350 reindeer by summer 1957 and to 6000 by summer 1963. The 6000 reindeer on St. Matthew Island in summer 1963 were then reduced by 99% to 42 by summer 1966. The evidence suggests that after growing at a high average annual rate of lamda = 1.32 for 19 years, the entire die-off occurred in winter 1963—64, making it the largest single-year crash ever recorded in any R. tarandus population. Although a supposedly meaningful decline in successful reproduction and early survival of calves was originally reported for the population between 1957 and 1963, our reevaluation indicates this is an error resulting from the wrong sample being used in the between-year comparison. The quantitative data indicate no meaningful change occurred, and the calf:cow ratio was about 60 calves:100 cows in both 1957 and 1963. Calf production and survival were high up to the crash, and in the die-off population the age distribution (72%, 1—3 years old and the sex ratio (69 males:100 females reflected a still fast-growing R. tarandus population. All of these parameters do not support the hypothesis that the limited abundance of the absolute food supply was at a lethal level between 1957 and 1963 or in winter 1963—64. We now know from other studies that a high density of R. tarandus is not a prerequisite for a major single-year winter die-off. Existing population dynamics data do not support lack of lichens as a major causative factor in this single-year crash. If a decline had been caused by the limitation of the absolute food supply, it would have followed a multi-year pattern—it would not have been a single-year event. There was no evidence of a sudden, massive, island-wide loss of the absolute food supply, or that its nutritional value was inadequate for sustaining the

    Recent experimental observations of time-dependent beatings in the two-dimensional echo-spectra of light-harvesting complexes at ambient temperatures have opened up the question of whether coherence and wave-like behaviour play a significant role in photosynthesis. We carry out a numerical study of the absorption and echo-spectra of the Fenna-Matthews-Olson (FMO) complex in Chlorobium tepidum and analyse the requirements in the theoretical model needed to reproduce beatings in the calculated spectra. The energy transfer in the FMO pigment-protein complex is theoretically described by an exciton Hamiltonian coupled to a phonon bath which accounts for the pigments' electronic and vibrational excitations, respectively. We use the hierarchical equations of motions method to treat the strong couplings in a non-perturbative way. We show that the oscillations in the two-dimensional echo-spectra persist in the presence of thermal noise and static disorder. (paper)

    Collective protein modes are expected to be important for facilitating energy transfer in the Fenna-Matthews-Olson (FMO) complex of photosynthetic green sulphur bacteria, however to date little work has focussed on the microscopic details of these vibrations. The nonlinear network model (NNM) provides a computationally inexpensive approach to studying vibrational modes at the microscopic level in large protein structures, whilst incorporating anharmonicity in the inter-residue interactions which can influence protein dynamics. We apply the NNM to the entire trimeric FMO complex and find evidence for the existence of nonlinear discrete breather modes. These modes tend to transfer energy to the highly connected core pigments, potentially opening up alternative excitation energy transfer routes through their influence on pigment properties. Incorporating localised modes based on these discrete breathers in the optical spectra calculations for FMO using ab initio site energies and excitonic couplings can substantially improve their agreement with experimental results.

Cuatro casos fueron de CBC (1,5% con edad promedio de 40,7 años. Cuatro de 7 tumores diagnosticados previamente como CBC, fueron reclasificados como TIF. DISCUSIÓN: el SCAP fue el tumor más frecuentemente asociado, tal como aparece reportado por otros autores. En esta serie se encontró el TIF con una mayor frecuencia que en la literatura revisada. El CBC fue el único tumor maligno y se presentó solo en adultos. Los resultados de esta serie evidencian un comportamiento benigno del NSJ, por lo que se debiera replantear la necesidad de resección precoz. La revisión histológica del diagnóstico inicial demuestra que lesiones benignas pueden ser confundidas fácilmente con CBC, sobreestimando el potencial maligno de este hamartoma.

    Femtosecond pulsed excitation of light-harvesting complexes creates oscillatory features in their response. This phenomenon has inspired a large body of work aimed at uncovering the origin of the coherent beatings and possible implications for function. Here we exploit site-directed mutagenesis to change the excitonic level structure in Fenna-Matthews-Olson (FMO) complexes and compare the coherences using broadband pump-probe spectroscopy. Our experiments detect two oscillation frequencies with dephasing on a picosecond timescale—both at 77 K and at room temperature. By studying these coherences with selective excitation pump-probe experiments, where pump excitation is in resonance only with the lowest excitonic state, we show that the key contributions to these oscillations stem from ground-state vibrational wavepackets. These experiments explicitly show that the coherences—although in the ground electronic state—can be probed at the absorption resonances of other bacteriochlorophyll molecules because of delocalization of the electronic excitation over several chromophores.

    2011-04-01

    Full Text Available One of the presumptions of this article is that most of the people in the nascent ‘Christian’ communities were ordinary people struggling with questions of living under harsh conditions in a country that was occupied by an enemy force. Another presumption is that the history of these ordinary people from antiquity needs to be heard. The article aimed, with the help of archaeology, cultural anthropology, social history of antiquity, literature of the time as well as other disciplines, to create a social context of Jesus and his disciples. The article approached the Gospels in the New Testament from the poor, the majority of people living in the 1st century Roman Empire. It gives a brief analysis of one of the poverty texts, namely Matthew 6:25–34. By means of interviews, stories of villagers in Tanzania, as well as their interpretations of the Gospel texts, have been documented. The people of Kinywang’anga serve as a test case for reading the ‘do not worry’ exhortation in the Matthean passage.

In undermatched specimens (the weld metal elastic limit is lower than that of BM the normalized yield load decreases compared to the elastic limit of BM. In overmatched specimens (the weld metal elastic limit is larger than that of BM, the yield load increases. This variation of the yield load depends on the degree of mismatch, and on the relation between weld size and crack length. The numerical results were compared with experimental values obtained with mismatched weld C(T specimens using an ASTM A 588 steel as base metal.

  10. Observations and operational model simulations reveal the impact of Hurricane Matthew (2016) on the Gulf Stream and coastal sea level

    2017-12-01

    In October 7-9, 2016, Hurricane Matthew moved along the southeastern coast of the U.S., causing major flooding and significant damage, even to locations farther north well away from the storm's winds. Various observations, such as tide gauge data, cable measurements of the Florida Current (FC) transport, satellite altimeter data and high-frequency radar data, were analyzed to evaluate the impact of the storm. The data show a dramatic decline in the FC flow and increased coastal sea level along the U.S. coast. Weakening of the Gulf Stream (GS) downstream from the storm's area contributed to high coastal sea levels farther north. Analyses of simulations of an operational hurricane-ocean coupled model reveal the disruption that the hurricane caused to the GS flow, including a decline in transport of ∼20 Sv (1 Sv = 106 m3 s-1). In comparison, the observed FC reached a maximum transport of ∼40 Sv before the storm on September 10 and a minimum of ∼20 Sv after the storm on October 12. The hurricane impacts both the geostrophic part of the GS and the wind-driven currents, generating inertial oscillations with velocities of up to ±1 m s-1. Analysis of the observed FC transport since 1982 indicated that the magnitude of the current weakening in October 2016 was quite rare (outside 3 standard deviations from the mean). Such a large FC weakening in the past occurred more often in October and November, but is extremely rare in June-August. Similar impacts on the FC from past tropical storms and hurricanes suggest that storms may contribute to seasonal and interannual variations in the FC. The results also demonstrated the extended range of coastal impacts that remote storms can cause through their influence on ocean currents.

    An interactively coupled atmosphere-ocean model was used to investigate the impacts of future ocean warming, both at the surface and the layers below, on the track and intensity of a hurricane and its associated storm surge and inundation. The category-5 hurricane Matthew (2016), which made landfall on the South Carolina coast of the United States, was used for the case study. Future ocean temperature changes and sea level rise (SLR) were estimated based on the projection of Inter-Governmental Panel on Climate Change (IPCC)'s Representative Concentration Pathway scenarios RCP 2.6 and RCP 8.5. After being validated with the present-day observational data, the model was applied to simulate the changes in track, intensity, storm surge and inundation that Hurricane Matthew would cause under future climate change scenarios. It was found that a significant increase in hurricane intensity, storm surge water level, and inundation area for Hurricane Matthew under future ocean warming and SLR scenarios. For example, under the RCP 8.5 scenario, the maximum wind speed would increase by 17 knots (14.2%), the minimum sea level pressure would decrease by 26 hPa (2.85%), and the inundated area would increase by 401 km2 (123%). By including the effect of SLR for the middle-21st-century scenario, the inundated area will further increase by up to 49.6%. The increase in the hurricane intensity and the inundated area was also found for the RCP 2.6 scenario. The response of sea surface temperature was analyzed to investigate the change in intensity. A comparison was made between the impacts when only the sea surface warming is considered versus when both the sea surface and the underneath layers are considered. These results showed that even without the effect of SLR, the storm surge level and the inundated area would be higher due to the increased hurricane intensity under the influence of the future warmer ocean temperature. The coupled effect of ocean warming and SLR would cause the

    The impacts on the Southeastern United States (SEUS, Western Atlantic) from Hurricane Irma in Sept 2017 were felt primarily on the active coastline with the third highest inland storm surge in Charleston and Savannah since the 19th Century. Coastal geometry, waves, and wind duration had a strong influence on the storm surge and coastal erosion impacts regionally. To the North and immediate South, impacts were much less. A full year after the 2016 hurricane season (Hurricane Matthew), the lack of regional recovery reduced protection against Irma. The most devastating impacts of Irma in the SAB occurred from 300 to 500 km away from the eye, on the opposite side of the Floridian peninsula. As Irma devastated the Caribbean, winds started to increases off the SAB on September 8 in the early morning, continuing for the next 3 days and blowing directly towards the SC and GA coasts. Tide gauges started to respond the night of September 8, while waves started arriving in the SEUS around Sept 6. Coastal erosion pre- and post-Irma has been calculated for Central SC using vertical and oblique aerial photos. Citizen Science initiatives through the Charleston Resilience Network have provided on-the-ground data during storms when transportation infrastructures were closed, and allow for ground-truth post-storm of surge and impacts. Said information was collected through Facebook, Google, and other social media. Pictures with timestamps and water heights were collected and are validating inundation flood maps generated for the Charleston SC region. The maps have 1-m horizontal and 7- to 15-cm vertical accuracy. Inundation surfaces were generated at MHHW up to a maximum surge in 6 inch increments. The flood extents of the modeled surge and the photographic evidence show a high correspondence. Storm surge measurements from RTK-GPS provide regional coverage of surge elevations from the coast, inland, and allow for testing of modeled results and model tuning. With Hurricane Irma

  17. Does immigration have a Matthew Effect? A cross-national analysis of international migration and international income inequality, 1960-2005.

    2013-05-01

    This paper empirically assesses how immigration affects international inequality by testing the relationship between immigration and national economic development across countries in different world income groups. A series of cross-national, longitudinal analyses demonstrate that, on average, immigration has a rather small, but positive long-term effect on development levels. However, the findings also indicate that immigration has a Matthew Effect (Merton, 1968) in the world-economy: immigration disproportionately benefits higher-income countries. Moreover, the wealthiest countries reap the largest gains from immigration. Thus, from the perspective of destination countries, immigration does not appear to be a panacea for international inequality. Instead, the results indicate that immigration actually reproduces, and even exacerbates, international inequality. Copyright © 2012 Elsevier Inc. All rights reserved.

  18. An efficient method to calculate excitation energy transfer in light-harvesting systems: application to the Fenna-Matthews-Olson complex

    A master equation derived from non-Markovian quantum state diffusion is used to calculate the excitation energy transfer in the photosynthetic Fenna-Matthews-Olson pigment-protein complex at various temperatures. This approach allows us to treat spectral densities that explicitly contain the coupling to internal vibrational modes of the chromophores. Moreover, the method is very efficient and as a result the transfer dynamics can be calculated within about 1 min on a standard PC, making systematic investigations w.r.t. parameter variations tractable. After demonstrating that our approach is able to reproduce the results of the numerically exact hierarchical equations of motion approach, we show how the inclusion of vibrational modes influences the transfer.

    Full Text Available Drawing on Jungian psychological type theory, the SIFT method of biblical hermeneutics and liturgical preaching suggests that the reading and proclaiming of scripture reflects the psychological type preferences of the reader and preacher. This thesis is examined amongst two samples of curates and training incumbents (N = 23, 27, serving in one Diocese of the Church of England, who completed the Myers-Briggs Type Indicator. Firstly, the narrative of the shepherds from Luke was discussed by groups organised according to scores on the perceiving process. In accordance with the theory, sensing types focused on details in the passage, but could reach no consensus on the larger picture, and intuitive types quickly identified an imaginative, integrative theme, but showed little interest in the details. Secondly, the narrative of the massacre of the infants from Matthew was discussed by groups organised according to scores on the judging process. In accordance with theory, the thinking types identified and analysed the big themes raised by the passage (political power, theodicy, obedience, whilst the feeling types placed much more emphasis on the impact that the passage may have on members of the congregation mourning the death of their child or grandchild.

  20. Visualization of Excitonic Structure in the Fenna-Matthews-Olson Photosynthetic Complex by Polarization-Dependent Two-Dimensional Electronic Spectroscopy

    Photosynthetic light-harvesting proceeds by the collection and highly efficient transfer of energy through a network of pigment-protein complexes. Inter-chromophore electronic couplings and interactions between pigments and the surrounding protein determine energy levels of excitonic states and dictate the mechanism of energy flow. The excitonic structure (orientation of excitonic transition dipoles) of pigment-protein complexes is generally deduced indirectly from x-ray crystallography in combination with predictions of transition energies and couplings in the chromophore site basis. Here, we demonstrate that coarse-grained excitonic structural information in the form of projection angles between transition dipole moments can be obtained from polarization-dependent two-dimensional electronic spectroscopy of an isotropic sample, particularly when the nonrephasing or free polarization decay signal rather than the photon echo signal is considered. The method provides an experimental link between atomic and electronic structure and accesses dynamical information with femtosecond time resolution. In an investigation of the Fenna-Matthews-Olson complex from green sulfur bacteria, energy transfer connecting two particular exciton states in the protein is isolated as being the primary contributor to a cross peak in the nonrephasing 2D spectrum at 400 fs under a specific sequence of polarized excitation pulses. The results suggest the possibility of designing experiments using combinations of tailored polarization sequences to separate and monitor individual relaxation pathways

    Two-dimensional (2D) photon-echo spectra of a single subunit of the Fenna-Matthews-Olson (FMO) bacteriochlorophyll trimer of Chlorobium tepidum are simulated, employing the equation-of-motion phase-matching approach (EOM-PMA). We consider a slightly extended version of the previously proposed Frenkel exciton model, which explicitly accounts for exciton coherences in the secular approximation. The study is motivated by a recent experiment reporting long-lived coherent oscillations in 2D transients [Engel et al., Nature 446, 782 (2007)] and aims primarily at accurate simulations of the spectroscopic signals, with the focus on oscillations of 2D peak intensities with population time. The EOM-PMA accurately accounts for finite pulse durations as well as pulse-overlap effects and does not invoke approximations apart from the weak-field limit for a given material system. The population relaxation parameters of the exciton model are taken from the literature. The effects of various dephasing mechanisms on coherence lifetimes are thoroughly studied. It is found that the experimentally detected multiple frequencies in peak oscillations cannot be reproduced by the employed FMO model, which calls for the development of a more sophisticated exciton model of the FMO complex.

  2. Simulating signatures of two-dimensional electronic spectra of the Fenna-Matthews-Olson complex: By using a numerical path integral

    A framework for simulating electronic spectra from photon-echo experiments is constructed by using a numerical path integral technique. This method is non-Markovian and nonperturbative and, more importantly, is not limited by a fixed form of the spectral density functions of the environment. Next, a two-dimensional (2D) third-order electronic spectrum of a dimer system is simulated. The spectrum is in agreement with the experimental and theoretical results previously reported [for example, M. Khalil, N. Demirdöven, and A. Tokmakoff, Phys. Rev. Lett. 90, 047401 (2003)]. Finally, a 2D third-order electronic spectrum of the Fenna-Matthews-Olson (FMO) complex is simulated by using the Debye, Ohmic, and Adolphs and Renger spectral density functions. It is shown that this method can clearly produce the spectral signatures of the FMO complex by using only the Adolphs and Renger spectral density function. Plots of the evolution of the diagonal and cross-peaks show that they are oscillating with the population time

    Hyperspectral infrared (IR) sounders provide high vertical resolution atmospheric sounding information that can improve the forecast skill in numerical weather prediction. Commonly, only clear radiances are assimilated, because IR sounder observations are highly affected by clouds. A cloud-clearing (CC) technique, which removes the cloud effects from an IR cloudy field of view (FOV) and derives the cloud-cleared radiances (CCRs) or clear-sky equivalent radiances, can be an alternative yet effective way to take advantage of the thermodynamic information from cloudy skies in data assimilation. This study develops a Visible Infrared Imaging Radiometer Suite (VIIRS)-based CC method for deriving Cross-track Infrared Sounder (CrIS) CCRs under partially cloudy conditions. Due to the lack of absorption bands on VIIRS, two important quality control steps are implemented in the CC process. Validation using VIIRS clear radiances indicates that the CC method can effectively obtain the CrIS CCRs for FOVs with partial cloud cover. To compare the impacts from assimilation of CrIS original radiances and CCRs, three experiments are carried out on two storm cases, Hurricane Joaquin (2015) and Hurricane Matthew (2016), using Gridpoint Statistical Interpolation assimilation system and Weather Research and Forecasting-Advanced Research Version models. At the analysis time, more CrIS observations are assimilated when using CrIS CCRs than with CrIS original radiances. Comparing temperature, specific humidity, and U/V winds with radiosondes indicates that the data impacts are growing larger with longer time forecasts (beyond 72 h forecast). Hurricane track forecasts also show improvements from the assimilation of CrIS CCRs due to better weather system forecasts. The impacts of CCRs on intensity are basically neutral with mixed positive and negative results.

    The nuclear periphery is a dynamic, structured environment, whose precise functions are essential for global processes-from nuclear, to cellular, to organismal. Its main components-the nuclear envelope (NE) with inner and outer nuclear membranes (INM and ONM), nuclear pore complexes (NPC), associated cytoskeletal and nucleoskeletal components as well as chromatin are conserved across eukaryotes (Fig. 1). In metazoans in particular, the structure and functions of nuclear periphery components are intensely researched partly because of their involvement in various human diseases. While far less is known about these in plants, the last few years have seen a significant increase in research activity in this area. Plant biologists are not only catching up with the animal field, but recent findings are pushing our advances in this field globally. In recognition of this developing field, the Annual Society of Experimental Biology Meeting in Salzburg kindly hosted a session co-organized by Katja Graumann and David E. Evans (Oxford Brookes University) highlighting new insights into plant nuclear envelope proteins and their interactions. This session brought together leading researchers with expertise in topics such as epigenetics, meiosis, nuclear pore structure and functions, nucleoskeleton and nuclear envelope composition. An open and friendly exchange of ideas was fundamental to the success of the meeting, which resulted in founding the International Plant Nucleus Consortium. This review highlights new developments in plant nuclear envelope research presented at the conference and their importance for the wider understanding of metazoan, yeast and plant nuclear envelope functions and properties.

    Full Text Available This article employed a case study to explore the theme of defilement as experienced in a Kenyan village. To provide a basis for the theological reflection on this case study, the article investigated two motifs in Matthew 15:10–11. ‘Hearing and understanding’ and ‘contrast’ [[Refer to PDF], ‘not…but’] was examined in respect of Leviticus 11:1–8 to determine the extent to which Matthew 15:10–11 depicts Jesus as ‘relativising’ the Mosaic law (Lv 11:1–8. This approach provided a basis to argue that defilement in Matthew 15:10–11 is not only a matter of external or ritual perspective, but of moral disposition. A methodology that combines both socio-rhetorical (Socio-rhetorical criticism is a methodology that derives value and meaning as an outcome of an active reading process that occurs within specific cultural contexts. In this case, the examiner produced the meaning of given texts by participating in a complex of socially constructed practices’ [Growler n.d., http://userwww.Service.emory. edu/~dgowler/chapter.htm] and narratological (Narratological criticism is the study of narratives that involves a kind of ‘structure and practice that illuminates temporality and human beings as temporal beings’.

These two methodologies greatly helped this article to explain the meaning and significance of defilement in Leviticus 11 with respect to the theological understanding of the Leviticus code of purity. This code presents a temporal view of defilement intended to reflect on the holiness and sovereignty of Yahweh, over and against idols of the surrounding nations. In addition, this

    Matthew Pelowski and his colleagues from the Helmut Leder lab [17] have made a remarkable contribution to the field of art perception by reviewing the extensive and varied literature (+300 references) on all the factors involved, from a coherent, synthetic perspective-The Vienna Integrated Model of top-down and bottom-up processes in Art Perception (VIMAP). VIMAP builds on earlier attempts from the same group to provide a comprehensive theoretical framework, but it is much wider in scope and richer in the number of levels and topics covered under its umbrella. It is particularly strong in its discussion of the different psychological processes that lead to a wide range of possible responses to art-from mundane, superficial reactions to more profound responses characterized as moving, disturbing, and transformative. By including physiological, emotional, and evaluative factors, the model is able to address truly unique, even intimate responses to art such as awe, chills, thrills, and the experience of the sublime. The unique way in which this rich set of possible responses to art is achieved is through a series of five mandatory consecutive processing steps (each with their own typical duration), followed by two conditional additional steps (which take more time). Three processing checks along this cascade lead to three more or less spontaneous outcomes (<60 sec) and two more time-consuming ones (see their Fig. 1 for an excellent overview). I have no doubt that VIMAP will inspire a whole generation of scientists investigating perception and appreciation of art, testing specific hypotheses derived from this framework for decades to come.

  4. Analytic investigation of extended Heitler-Matthews model

    Many features of extensive air showers are qualitatively well described by the Heitler cascade model and its extensions. The core of a shower is given by hadrons that interact with air nuclei. After each interaction some of these hadrons decay and feed the electromagnetic shower component. The most important parameters of such hadronic interactions are inelasticity, multiplicity, and the ratio of charged vs. neutral particles. However, in analytic considerations approximations are needed to include the characteristics of hadron production. We discuss extensions of the simple cascade model by analytic description of air showers by cascade models which include also the elasticity, and derive the number of produced muons. In a second step we apply this model to calculate the dependence of the shower center of gravity on model parameters. The depth of the center of gravity is closely related to that of the shower maximum, which is a commonly-used composition-sensitive observable.

    In India, power generation and distribution is the responsibility of the different States that have their own electricity boards through which this is done. Of late, in the wake of liberalization, many attempts have been made to reform the power sector, in the light of the poor performance of these boards. The Haryana State Electricity Board (HSEB) is the primary supplier of power in one of the States called Haryana. For quite some years, it was facing problems with revenues, low PLF etc. A review was done and counselling help sought from prominent Consultancy firms. As a result a large scale restructuring was planned. The present paper looks at the attempts of HSEB at restructuring and the consequences of the restructuring efforts. (authors)

  11. Women’s stories implying aspects of anti-Judaism with Christological depiction in Matthew

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available This study focuses on the women’s stories that imply aspects of anti-Judaism within Matthew’s depiction of Christology, which is called Matthew’s theology. In fact, Matthew’s community opposed the Jewish system and Jewish leaders and parted from its parent body. Even though Matthew’s community was still similar to the Jewish system, it had significant differences as well. The study discusses these aspects of anti-Judaism that appear in the woman’s stories that include the genealogy of Jesus, the haemorrhaging woman, the Canaanite woman, and the women at the cross and Jesus’ tomb. This study shows proof and examples of anti-Judaism within the stories and thoroughly analyses them. Therefore, it can be confirmed that the women’s stories imply aspects of anti-Judaism with Christological depictions by Matthew’s theological tendency.

    Reflecting the theme of the 2015 Gerontological Society of America (GSA) Annual Scientific Meeting, "Aging as a Lifelong Process," this paper examines intersections between aging processes and their environmental context, develops theory regarding constructive developmental processes and their environmental context, and considers potential implications for conceptualizing and creating aging-friendly communities. The first section examines the primary goals of aging-friendly communities, that is, promoting elder well-being. The second section explores the role of environmental pathways in fostering well-being throughout the lifecourse. The third section presents a new Process Model of Constructive Aging that identifies key developmental processes at the intersection of individual and environmental pathways. The final section considers potential implications for creating aging-friendly communities, including ways in which cities and towns can promote the ability of community members to live fully throughout their lives, and identifies some key conceptual and empirical challenges affecting the future of the field. © The Author 2017.

  20. ’The origins of art history in Hungary’’’ trans. and ed. Matthew Rampley

    Directory of Open Access Journals (Sweden)

    Ernő Marosi

    2013-06-01

    Full Text Available This text examines the early development of art history in Hungary, from antiquarianism to the 1880s. As with other states in Europe, a key driver behind the establishment of 'scientific' art history was the rising concern for ancient monuments. In particular, they came to be seen as repositories of collective memory, which increasingly came to be equated with 'national tradition'. In the early stages of this process, a prominent role was played by the Central Commission for the Investigation and Protection of Monuments in Vienna, but once Hungary gained almost complete autonomy in the Habsburg Monarchy after 1867, it was Hungarian art historians and the Hungarian Monuments Commission in Budapest that took over responsibility. The period thus saw the emergence of Hungarian art history from under Viennese tutelage, and with the emergence of a generation of art historians who established a Hungarian-language historiographic literature.

    2015-03-01

    In pursuit of more mindful notions of hybridity, this review essay provides a series of reflections on Mathew Weinstein's representations of Street Medics and `sciences for the red zones of neoliberalism'. My analysis draws on three popular ways of thinking with boundaries to offer a critical reading of the boundary-work that the essay performs with respect to three dialectics: (1) technical and political; (2) disciplinarily and multidisciplinarities; and (3) structures and agencies. I conclude with reflections on my boundary labour as a researcher, writer and pedagogue and how such cultural work might learn to live better with difference, ambiguities, hybrids and cross-hybrid learning.

  2. Examining the "Matthew Effect" on the motivation and ability to make lifestyle changes in 217 heart rehabilitation patients.

    Mildestvedt, Thomas; Meland, Eivind

    2007-01-01

    Those who are socioeconomically disadvantaged and people with emotional problems have a poorer prognosis for cardiovascular disease. The authors wanted to examine: (1) what effect household income, emotional status, high-risk smoking status, and severity of heart disease had on the ability of individuals to make dietary and exercise improvements after heart disease and (2) to what extent unfavourable lifestyle outcomes among disadvantaged people were mediated by motivational problems. A two-year follow-up study of the combined cohorts of a randomized controlled trial. Level of exercise and present dietary habits were measured at inclusion and after 6 and 24 months. Different motivational factors and emotional distress were measured during rehabilitation. Autonomous self-regulation was lowest among smokers (b = -0.31, p = 0.02) and female participants (b = 0.39, p = 0.004). Participants with high scores of emotional distress predicted lower motivation for all the measures. We found no association between socioeconomic status (household income) and the ability to perform lifestyle changes. Current smoking status predicted lower ability to obtain lifestyle changes on all measures. Emotional distress was related to lower ability to increase physical activity at 6 months' but not at 24 months' follow-up. The mediating effects of motivational factors were insignificant. The results of this study do not support the suspicion that preventive efforts accentuate the socioeconomic differences in cardiovascular health. Health-promotive efforts after heart disease should safeguard that high-risk groups such as smokers are not discouraged from improving their lifestyle in other areas.

    2012-01-01

    Long-lived excitonic coherence in photosynthetic proteins has become an exciting area of research because it may provide design principles for enhancing the efficiency of energy transfer in a broad range of materials. In this publication, we provide new evidence that long-lived excitonic coherence in the Fenna-Mathew-Olson pigment-protein (FMO) complex is consistent with the assumption of cross correlation in the site basis, indicating that each site shares bath fluctuations. We analyze the structure and character of the beating crosspeak between the two lowest energy excitons in two-dimensional (2D) electronic spectra of the FMO Complex. To isolate this dynamic signature, we use the two-dimensional linear prediction Z-transform as a platform for filtering coherent beating signatures within 2D spectra. By separating signals into components in frequency and decay rate representations, we are able to improve resolution and isolate specific coherences. This strategy permits analysis of the shape, position, character, and phase of these features. Simulations of the crosspeak between excitons 1 and 2 in FMO under different regimes of cross correlation verify that statistically independent site fluctuations do not account for the elongation and persistence of the dynamic crosspeak. To reproduce the experimental results, we invoke near complete correlation in the fluctuations experienced by the sites associated with excitons 1 and 2. This model contradicts ab initio quantum mechanic/molecular mechanics simulations that observe no correlation between the energies of individual sites. This contradiction suggests that a new physical model for long-lived coherence may be necessary. The data presented here details experimental results that must be reproduced for a physical model of quantum coherence in photosynthetic energy transfer.

    Single-Event Burnout (SEB) of bipolar junction transistors (BJTs) has been observed nondestructively. It was revealed that all the NPN BJTs, including small signal transistors, with thinner epitaxial layers were inherently susceptible to the SEB phenomenon. It was demonstrated that several design parameters of BJTs were responsible for SEB susceptibility. Additionally, destructive and nondestructive modes of SEB were identified.

    Emil Filla

    2013-06-01

    Full Text Available Emil Filla (1882-1953 was one of the leading modernist painters working in Prague before the First World War. Anxious to avoid the limitations of the provincial art world of Prague, he avidly consumed the most advanced artistic practices of the major art centres of the time, culminating in a quite personal appropriation and interpretation of Cubism. A close reading of Filla’s article reveals obvious traces of Vienna School thinking; the most striking is his repeated reference to the artistic will (vůle umělecká which is a direct Czech translation of Riegl’s ‘Kunstwollen’. Filla’s interest, too, in how El Greco treated spatial relations, bears more than a passing resemblance to Riegl’s exploration of figure-ground relations in Late Roman Art Industry.

    Full Text Available The text aims to bring attention of the Czech readers to Petrie's contributions to the eugenics movement in Great Britain. It describes his close association with Francis Galton and his resulting pronounced views on eugenics and shows how Petrie's racist opinions and involvement in eugenics influenced hi s work as an archaeologist and historian. An attempt is made to understand Petrie's views in the context ofhis times instead of condemning him for hi s appalling conclusions motivated by his racism and eugenics beliefs. The text offers a perspective which enables the readers to consider Petrie's thoughts in relation to the eugenic movement which was not on ly favoured by many ofhis contemporaries, but also had many supporters Jong after Petrie's death. Any consideration of the influence of past ideologies and context on Petrie's thinking and research also brings forward an unanswerable question ofhow much each one of u s is influenced by the ideologies and the context(s prevalent in present times and culture.

  16. Discussions On Worst-Case Test Condition For Single Event Burnout

    Liu, Sandra; Zafrani, Max; Sherman, Phillip

    2011-10-01

    This paper discusses the failure characteristics of single- event burnout (SEB) on power MOSFETs based on analyzing the quasi-stationary avalanche simulation curves. The analyses show the worst-case test condition for SEB would be using the ion that has the highest mass that would result in the highest transient current due to charge deposition and displacement damage. The analyses also show it is possible to build power MOSFETs that will not exhibit SEB even when tested with the heaviest ion, which have been verified by heavy ion test data on SEB sensitive and SEB immune devices.

    Poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) copolymer biomedical elastomer was covalently grafted with poly(ethylene glycol) methyl ether methacrylate (PEGMA) via a photo-initiated graft polymerization technique. The surface graft polymerization of SEBS with PEGMA was verified by ATR-FTIR and XPS. Effect of graft polymerization parameters, i.e., monomer concentration, UV irradiation time and initiator concentration on the grafting density was investigated. Comparing with the virgin SEBS film, the PEGMA-modified SEBS film presented an enhanced wettability and a larger surface energy. Besides, the surface grafting of PEGMA imparted excellent anti-platelet adhesion and anti-protein adsorption to the SEBS surface.

  18. Sulfasalazine Attenuates Staphylococcal Enterotoxin B-Induced Immune Responses

    2015-02-01

    Full Text Available Staphylococcal enterotoxin B (SEB and related exotoxins are important virulence factors produced by Staphylococcus aureus as they cause human diseases such as food poisoning and toxic shock. These toxins bind directly to cells of the immune system resulting in hyperactivation of both T lymphocytes and monocytes/macrophages. The excessive release of proinflammatory cytokines from these cells mediates the toxic effects of SEB. This study examined the inhibitory activities of an anti-inflammatory drug, sulfasalazine, on SEB-stimulated human peripheral blood mononuclear cells (PBMC. Sulfasalazine dose-dependently inhibited tumor necrosis factor α, interleukin 1 (IL-1 β, IL-2, IL-6, interferon γ (IFNγ, and various chemotactic cytokines from SEB-stimulated human PBMC. Sulfasalazine also potently blocked SEB-induced T cell proliferation and NFκB activation. These results suggest that sulfasalazine might be useful in mitigating the toxic effects of SEB by blocking SEB-induced host inflammatory cascade and signaling pathways.

    Full Text Available Previous research suggests that Learning Difficulties in Reading and Mathematics are highly related. This work tried to test in children if the presence of specific Learning Difficulties in Mathematics (LDM was related to poor results in Intellectual Quotient (IQ tests. Also, it is tested if differences in IQ are related to different mathematical performances. Therefore, the IQs of 12 LDM children enrolled in the first year of Primary School were compared with the IQs of 20 LDM children enrolled in the third year of Primary School. The IQs of LDM children were compared with the IQs of two non-LDM groups of the same cohorts. Among other results, it was observed that the IQs of the oldest LDM children were significantly lower than these of the youngest children, while no differences were found among non-LDM children. Furthermore, the presence of a high or low IQ did not always imply an equally high or low mathematical performance in the scholars.

    A feasibility study on an imaging technique of a therapeutic proton-beam trajectory using a gamma camera by measuring secondary electron bremsstrahlung (SEB) was performed by means of Monte Carlo simulations and a beam-irradiation experiment. From the simulation and experimental results, it was found that a significant amount of SEB yield exists between the beam-injection surface and the range position along the beam axis and the beam trajectory is clearly imaged by the SEB yield. It is concluded that the SEB imaging is a promising technique for monitoring of therapeutic proton-beam trajectories.

    Full Text Available Tendo a oportunidade de estudar fragmentos de pele retirados de diversas regiões, algumas providas de abundante revestimento capilar, em um caso de autopsia de doente com sindromo bolhoso do grupo pênfigo, chamaram a nossa atenção as alterações histologicas dos folículos pilo-sebaceso, sôbre as quais não encontramos referencia especial na literatura que nos foi dado consultar.Several skin fragments were available for histological study some of them from hairy regions in a case of pemphigus vulgaris observed in Asunción, Paraguay, which came to autopsy. The lesions on the skin are similar to those described in "fogo selvagem", a subtype of pemphigus which is endemic and sometimes epidemic in South America. The hair follicle shows hyperplasia of the outer sheath (acanthosis, acantholysis, dyskeratosis as well as necrosis of epithelial cells, dilatation of its mouth, loosening and loos of the hair. The first changes mentioned are more or less similar to those described in the epidermis. The striking finding, however, is the presence in some of them of intranuclear inclusion bodies in most cells of the outer sheath. The enlarged nuclei show thickening of the nuclear membrane and condensation of most intranuclear structures in acidophilic corpuscles of irregular shape, sometimes single, other times multiple, always separated from the nuclear membrane by a clear space apparently deprived of structure. Remaining portions of the linin reticulum are sometimes recognised besides the inclusion bodies. Minute granules suggestive of elementary corpuscles appear scattered in other nuclei faintly blue stained (advanced stages of the intranuclear inclusion bodies?. Intranuclear inclusion bodies could be demonstrated also in the epithelial cells of sebaceous glands which presented changes similar to those found in the hair follicles, but never in the cells of the epidermis. The histological changes in the epidermis however were quite similar to those just mentioned in the above structures.

    Graphical abstract: - Highlights: • Grafting concentration of PEG was defined by the peak-area ratio of [C–O]/[C]. • Quantitatively investigated the adsorption processes of BSA and fibrinogen using QCM-D. • The inactivated BSA on SEBS surface could induce the subsequent fibrinogen adsorption. • SEBS-g-PEG with graft concentration of 0.207 has excellent protein resistance. - Abstract: Protein adsorption is a dynamic process and plays a major role in determining the hemocompatibility of biomaterials. We have obtained different poly (ethylene glycol) (PEG) graft concentrations of SEBS-g-PEG and the surface chemical compositions are confirmed by X-ray photoelectron spectroscopy (XPS). Graft concentration is defined by peak-area ratio of [C-O]/[C] on modified SEBS surface. With increasing graft concentration, water contact angles of the modified SEBS have significantly decreased. The platelet adhesion and static protein adsorption demonstrate that the hemocompatibility of copolymers films are improved effectively and SEBS-g-PEG-2 with larger graft concentration has more superior anticoagulation than that of SEBS-g-PEG-1. Moreover, we have quantitatively investigated the adsorption process of bovine serum albumin (BSA) and fibrinogen (Fib) on the surfaces of pristine SEBS and modified SEBS using quartz crystal microbalance with dissipation (QCM-D) in real time. The results indicate that the inactivated BSA on the pristine SEBS can continuously induce the subsequent Fib adsorption. The hemocompatibility of SEBS-g-PEG-2 with the graft concentration of 0.207 has excellent anti-protein property and the bio-inert BSA layer on the film can resist the subsequent Fib adsorption.

    Staphylococcus aureus are potent human pathogens possessing arsenal of virulence factors. Staphylococcal food poisoning (SFP) and respiratory infections mediated by staphylococcal enterotoxin B (SEB) are common clinical manifestations. Many diagnostic techniques are based on serological detection and quantification of SEB in different food and clinical samples. Aptamers are known as new therapeutic and detection tools which are available in different ssDNA, dsDNA and protein structures. In this study, we used a new set of ssDNA aptamers against SEB. The methods used included preparation of a dsDNA library using standard SEB protein as the target analyte, affinity chromatography matrix in microfuge tubes, SELEX procedures to isolate specific ssDNA-aptamer as an affinity ligand, aptamer purification using ethanol precipitation method, affinity binding assay using ELISA, aptamer cloning and specificity test. Among 12 readable sequences, three of them were selected as the most appropriate aptamer because of their affinity and specificity to SEB. This study presents a new set of ssDNA aptamer with favorable selectivity to SEB through 12 rounds of SELEX. Selected aptamers were used to detect SEB in infected serum samples. Results showed that SEB c1 aptamer (2 µg SEB/100 nM aptamer) had favorable specificity to SEB (kd  = 2.3 × 10(-11) ). In conclusion, aptamers can be considered as useful tools for detecting and evaluating SEB. The results showed that affinity chromatography was an affordable assay with acceptable accuracy to isolate sensitive and selective novel aptamers. Copyright © 2016 John Wiley & Sons, Ltd.

    2010-10-27

    A new sandwich-type electrochemical immunoassay for ultrasensitive detection of staphylococcal enterotoxin B (SEB) in food was developed using horseradish peroxidase-nanosilica-doped multiwalled carbon nanotubes (HRPSiCNTs) for signal amplification. Rabbit polyclonal anti-SEB antibodies immobilized on the screen-printed carbon electrode (SPCE) and covalently bound to the HRPSiCNTs were used as capture antibodies and detection antibodies, respectively. In the presence of SEB analyte, the sandwich-type immunocomplex could be formed between the immobilized anti-SEB on the SPCE and anti-SEB-labeled HRPSiCNTs, and the carried HRP could catalyze the electrochemical reduction of H2O2 with the help of thionine. The high content of HRP in the HRPSiCNTs could greatly amplify the electrochemical signal. Under optimal conditions, the reduction current increased with the increase of SEB in the sample, and exhibited a dynamic range of 0.05-15 ng/mL with a low detection limit (LOD) of 10 pg/mL SEB (at 3σ). Intra- and interassay coefficients of variation were below 10%. In addition, the assay was evaluated with SEB spiked samples including watermelon juice, soymilk, apple juice, and pork food, receiving excellent correlation with results from commercially available enzyme-linked immunosorbent assay (ELISA).

    Full Text Available Twenty-one species of sponges were recorded under the class of Demospongiae and Calcareous sponges of which 19 species were new to Agatti reef. A total of 113 Sponge endosymbiotic bacterial strains were isolated from twenty-one species of sponges and screened for antimicrobial activity. Five bacterial strains of sponge endosymbiotic bacteria (SEB namely SEB32, SEB33, SEB36, SEB43 and SEB51 showed antimicrobial activity against virulent marine fish pathogens such as Vibrio alginolyticus, Vibrio vulnificus, Vibrio parahaemolyticus, Aeromonas salmonicida, Flavobacterium sp., Edwardsiella sp., Proteus mirabilis and Citrobacter brackii. The secondary metabolites produced by SEB32 from sponge Dysidea fragilis (Montagu, 1818 [48] was selected with broad range of antibacterial activity and subjected for production, characterization by series of chromatography techniques and spectroscopic methods. Based on the results of FT-IR and mass spectrometry, the active molecule was tentatively predicted as “Pyrrol” and the structure is Pyrrolo[1,2-a]pyrazine-1,4-dione, hexahydro- with molecular formula of C7H10N2O2. The LC50 of active molecule was 31 μg/ml and molecular weight of the metabolites was 154. The potential strain SEB32 was identified by gene sequence (GenBank Accession number JX985748 and identified as Bacillus sp. from GenBank database.

    Robust evapotranspiration (ET) models are required to predict water usage in a variety of terrestrial ecosystems under different geographical and agrometeorological conditions. As a result, several remote sensing-based surface energy balance (SEB) models have been developed to estimate ET over large regions. However, comparison of the performance of several SEB models at the same site is limited. In addition, none of the SEB models have been evaluated for their ability to predict ET in rain-fed high biomass sorghum grown for biofuel production. In this paper, we evaluated the performance of five widely used single-source SEB models, namely Surface Energy Balance Algorithm for Land (SEBAL), Mapping ET with Internalized Calibration (METRIC), Surface Energy Balance System (SEBS), Simplified Surface Energy Balance Index (S-SEBI), and operational Simplified Surface Energy Balance (SSEBop), for estimating ET over a high biomass sorghum field during the 2012 and 2013 growing seasons. The predicted ET values were compared against eddy covariance (EC) measured ET (ETEC) for 19 cloud-free Landsat image. In general, S-SEBI, SEBAL, and SEBS performed reasonably well for the study period, while METRIC and SSEBop performed poorly. All SEB models substantially overestimated ET under extremely dry conditions as they underestimated sensible heat (H) and overestimated latent heat (LE) fluxes under dry conditions during the partitioning of available energy. METRIC, SEBAL, and SEBS overestimated LE regardless of wet or dry periods. Consequently, predicted seasonal cumulative ET by METRIC, SEBAL, and SEBS were higher than seasonal cumulative ETEC in both seasons. In contrast, S-SEBI and SSEBop substantially underestimated ET under too wet conditions, and predicted seasonal cumulative ET by S-SEBI and SSEBop were lower than seasonal cumulative ETEC in the relatively wetter 2013 growing season. Our results indicate the necessity of inclusion of soil moisture or plant water stress

    Graphical abstract: -- Highlights: •An ultrasensitive FRET aptasensor was developed for staphylococcal enterotoxin B determination. •SEB was recognized by SEB aptamer with high affinity and specificity. •The Mn 2+ doped NaYF 4 :Yb/Er UCNPs used as donor to quencher dye (BHQ 3 ) in new FRET. •The fluorescence intensity was prominently amplified using an exonuclease-catalyzed target recycling strategy. -- Abstract: An ultrasensitive fluorescence resonance energy transfer (FRET) bioassay was developed to detect staphylococcal enterotoxin B (SEB), a low molecular exotoxin, using an aptamer-affinity method coupled with upconversion nanoparticles (UCNPs)-sensing, and the fluorescence intensity was prominently enhanced using an exonuclease-catalyzed target recycling strategy. To construct this aptasensor, both fluorescence donor probes (complementary DNA 1 –UCNPs) and fluorescence quencher probes (complementary DNA 2 –Black Hole Quencher 3 (BHQ 3 )) were hybridized to an SEB aptamer, and double-strand oligonucleotides were fabricated, which quenched the fluorescence of the UCNPs via FRET. The formation of an aptamer–SEB complex in the presence of the SEB analyte resulted in not only the dissociation of aptamer from the double-strand DNA but also both the disruption of the FRET system and the restoration of the UCNPs fluorescence. In addition, the SEB was liberated from the aptamer–SEB complex using exonuclease I, an exonuclease specific to single-stranded DNA, for analyte recycling by selectively digesting a particular DNA (SEB aptamer). Based on this exonuclease-catalyzed target recycling strategy, an amplified fluorescence intensity could be produced using different SEB concentrations. Using optimized experimental conditions produced an ultrasensitive aptasensor for the detection of SEB, with a wide linear range of 0.001–1 ng mL −1 and a lower detection limit (LOD) of 0.3 pg mL −1 SEB (at 3σ). The fabricated aptasensor was used to measure SEB in a

    Utility-scale solar power plants are a rapidly growing component of the solar energy sector. Utility-scale photovoltaic (PV) solar power generation in the United States has increased by 867% since 2012 (EIA, 2016). This expansion is likely to continue as the cost PV technologies decrease. While most agree that solar power can decrease greenhouse gas emissions, the biophysical effects of PV systems on surface energy balance (SEB), and implications for surface climate, are not well understood. To our knowledge, there has never been a detailed observational study of SEB at a utility-scale solar array. This study presents data from an eddy covariance observational tower, temporarily placed above a utility-scale PV array in Southern Arizona. Comparison of PV SEB with a reference (unmodified) site, shows that solar panels can alter the SEB and near surface climate. SEB observations are used to develop and validate a new and more complete SEB PV model. In addition, the PV model is compared to simpler PV modelling methods. The simpler PV models produce differing results to our newly developed model and cannot capture the more complex processes that influence PV SEB. Finally, hypothetical scenarios of PV expansion across the continental United States (CONUS) were developed using various spatial mapping criteria. CONUS simulations of PV expansion reveal regional variability in biophysical effects of PV expansion. The study presents the first rigorous and validated simulations of the biophysical effects of utility-scale PV arrays.

    Full Text Available Abstract Background During clinical practice, we noticed that some patients with both ulcerative colitis (UC and chronic rhinosinusitis (CRS showed amelioration of UC after treatment of CRS. This study was designed to identify a possible association between CRS and UC. Methods Thirty-two patients with both CRS and UC received treatment with functional endoscopic sinus surgery (FESS for CRS. Clinical symptom scores for CRS and UC, as well as serum levels of anti-Staphylococcal enterotoxin B (SEB were evaluated at week 0 and week 12. Sinus wash fluid SEB content was measured with enzyme-linked immunosorbent assay (ELISA. The surgically removed tissues were cultured to identify growth of Staphylococcus. aureus (S. aureus. Immunohistochemistry was employed to identify anti-SEB positive cells in the colonic mucosa. Colonic biopsies were obtained and incubated with SEB. Mast cell activation in the colonic mucosa in response to incubation with SEB was observed with electron microscopy and immunoassay. Results The clinical symptom scores of CRS and UC severe scores (UCSS were significantly reduced in the UC-CRS patients after FESS. The number of cultured S. aureus colonies from the surgically removed sinus mucosa significantly correlated with the decrease in UCSS. High levels of SEB were detected in the sinus wash fluids of the patients with UC-CRS. Histamine and tryptase release was significantly higher in the culture supernate in the patients with UC-CRS than the patients with UC-only and normal controls. Anti-SEB positive cells were located in the colonic mucosa. Conclusion The pathogenesis of UC in some patients may be associated with their pre-existing CRS by a mechanism of swallowing sinusitis-derived SEB. We speculate that SEB initiates inappropriate immune reactions and inflammation in the colonic mucosa that further progresses to UC.

    Fermilab has adopted the Source Evaluation Board (SEB) method for procuring certain major technical components of the Fermilab Main Injector. The SEB procedure is designed to ensure the efficient and effective expenditure of Government funds at the same time that it optimizes the opportunity for attainment of project objectives. A qualitative trade-off is allowed between price and technical factors. The process involves a large amount of work and is only justified for a very limited number of procurements. Fermilab has gained experience with the SEB process in awarding subcontracts for major subassemblies of the Fermilab Main Injector dipoles

    The authors clarified the clinical significance of the measurement of serum concentrations of specific IgE antibodies to staphylococcal enterotoxin (SE) A- and SEB in atopic dermatitis (AD). The serum concentrations of SEA- and SEB-specific IgE antibodies in 140 pediatric patients with AD were measured with an immuno CAP -radioallergosorbent test system (RAST). To check the cross-reaction of specific IgE antibodies to SEA/SEB and other allergens, the CAP RAST fluorescent enzyme immunoassay inhibition test was performed. Forty-seven patients (33.6%) tested positive for either SEA- or SEB-specific IgE antibodies. School children showed higher positive rates of SEA/SEB-specific IgE antibodies than infants or young children. The patients with severe AD and those with exacerbation of symptoms in summer, had higher positive rates of SEA/SEB-specific IgE antibodies than patients with mild AD or those with exacerbation in winter. In addition, the positive rates of specific IgE antibodies to both dog-dander and cat-dander were higher in patients with positive SEA/SEB-specific IgE antibodies than in patients with negative ones. No cross-reactions occurred among specific IgE antibodies to SEA/SEB and dog/cat dander with one patient's serum, which had positive IgE-specific antibodies against cat/dog dander and SEA/SEB. The positive rate of SEA/SEB-specific IgE antibodies in the patients with dogs and/or cats as pets was 48.4%, which was higher than in those with no pets. Atopic dermatitis patients who exhibit high positive rates of SEA/SEB-specific IgE antibodies were found to be school children, severe cases, cases with high serum concentrations of total IgE, cases with exacerbation in summer, and cases with dogs and/or cats as pets. The measurement of serum concentrations of specific IgE antibodies to SEA and SEB, thus has some value for evaluating AD patients.

    2D MEDICI simulator is used to investigate the effect of Single Event Burnout (SEB) for n-channel power VDMOSFETs. The simulation results are consistent with experimental results which have been published. The simulation results are of great interest for a better understanding of the occurrence of events. The effects of the minority carrier lifetime in the base region, the base width and the emitter doping density on SEB susceptibility are verified. Some hardening solutions to SEB are provided. The work shows that the 2D simulator MEDICI is an useful tool for burnout prediction and for the evaluation of hardening solutions. (authors)

    1991-01-01

    Groupware is a class of computer based systems that support groups engaged in a common task (or goal) and that provide an interface to a shared environment. A potential application for groupware is the source evaluation board (SEB) process used in the procurement of government contracts. This study was undertaken to (1) identify parts of the SEB process which are candidates for groupware supports; and (2) identify tools which could be used to support the candidate process. Two processes of the SEB were identified as good candidates for groupware support: (1) document generation - a coordination and communication process required to present and document the findings of an SEB; and (2) group decision making - a highly analytical and integrative decision process requiring a clear and supportable outcome.

    2014-01-01

    Staphylococcal enterotoxin B (SEB) is a potent exotoxin produced by the Staphylococcus aureus. This toxin is classified as a superantigen because of its ability to directly bind with MHC-II class molecules followed by activation of a large proportion of T cells bearing specific Vβ-T cell receptors. Commonly associated with classic food poisoning, SEB has also been shown to induce toxic shock syndrome, and is also considered to be a potential biological warfare agent because it is easily aerosolized. In the present study, we assessed the ability of indole-3-carbinol (I3C) and one of its byproducts, 3,3′-diindolylmethane (DIM), found in cruciferous vegetables, to counteract the effects of SEB-induced activation of T cells in mice. Both I3C and DIM were found to decrease the activation, proliferation, and cytokine production by SEB-activated Vβ8 + T cells in vitro and in vivo. Interestingly, inhibitors of histone deacetylase class I (HDAC-I), but not class II (HDAC-II), showed significant decrease in SEB-induced T cell activation and cytokine production, thereby suggesting that epigenetic modulation plays a critical role in the regulation of SEB-induced inflammation. In addition, I3C and DIM caused a decrease in HDAC-I but not HDAC-II in SEB-activated T cells, thereby suggesting that I3C and DIM may inhibit SEB-mediated T cell activation by acting as HDAC-I inhibitors. These studies not only suggest for the first time that plant-derived indoles are potent suppressors of SEB-induced T cell activation and cytokine storm but also that they may mediate these effects by acting as HDAC inhibitors. - Highlights: • I3C and DIM reduce SEB-induced T cell activation and inflammatory cytokines. • Inhibiting class I HDACs reduces T cell activation and inflammatory cytokines. • Inhibiting class II HDACs increases T cell activation and inflammatory cytokines. • I3C and DIM selectively reduce mRNA expression of class I HDACs. • Novel use and mechanism to counteract SEB

    Directory of Open Access Journals (Sweden)

    Philip B Busbee

    Full Text Available Staphylococcal enterotoxin B (SEB is a potent superantigen capable of inducing inflammation characterized by robust immune cell activation and proinflammatory cytokine release. Exposure to SEB can result in food poisoning as well as fatal conditions such as toxic shock syndrome. In the current study, we investigated the effect of natural indoles including indole-3-carbinol (I3C and 3,3'-diindolylmethane (DIM on SEB-mediated liver injury. Injection of SEB into D-galactosamine-sensitized female C57BL/6 mice resulted in liver injury as indicated by an increase in enzyme aspartate transaminase (AST levels, induction of inflammatory cytokines, and massive infiltration of immune cells into the liver. Administration of I3C and DIM (40 mg/kg, by intraperitonal injection, attenuated SEB-induced acute liver injury, as evidenced by decrease in AST levels, inflammatory cytokines and cellular infiltration in the liver. I3C and DIM triggered apoptosis in SEB-activated T cells primarily through activation of the intrinsic mitochondrial pathway. In addition, inhibitor studies involving caspases revealed that I3C and DIM-mediated apoptosis in these activated cells was dependent on caspase-2 but independent of caspase-8, 9 and 3. In addition, I3C and DIM caused a decrease in Bcl-2 expression. Both compounds also down-regulated miR-31, which directly targets caspase-2 and influences apoptosis in SEB-activated cells. Our data demonstrate for the first time that indoles can effectively suppress acute hepatic inflammation caused by SEB and that this may be mediated by decreased expression of miR-31 and consequent caspase-2-dependent apoptosis in T cells.

  11. Financial structure in the Indian power sector

    International Nuclear Information System (INIS)

    Carstairs, Jamie; Ehrhardt, David

    1995-01-01

    In India, the private power initiative of 1991 has offered on solution to the financing problem - the private financing of generation against long-term power purchase agreements. However, this approach encounters a major problem, the financial weakness of the purchasing agents, the state electricity boards, that play a dominant role in most state's power sectors. At present the SEBs are mostly loss making; even the best performers realize returns on assets well below the cost of capital that they now face. The situation is likely to become worse as costs rise, further weakening the ability of the SEBs to sign credible long-term purchase contracts. The private sector has responded by trying to reduce its exposure to SEBs through obtaining guarantees from state and central governments. There are a number of responses to this problem. The SEBs could try to become financially stronger through both cost reduction and increased revenues from higher tariffs and better collection. However, to make the SEBs and EDs into credible long-term power purchasers, power sector reform and regulation is needed. As these actions will take time, other responses could be investigated such as reducing the role of state power utilities by, for example, giving private generators direct access to industrial consumers. The long-term solution requires more profitable SEBs, if these bodies are to continue to play a dominant role in state-level electricity provision. Profitable SEBs will have access to finance from a range of domestic and international sources. The article finishes with consideration of the factors that will affect the optimal capital structure for SEBs. (author)

    Full Text Available The article considers the role of the absolute and relative income in determining the subjective economic well-being. It is shown that the relationship of the income to SEB is curvilinear with the increase of marginal utility for a higher income. At low income levels its effect on SEB is determined not by its absolute, but by its relative value based on the comparisons with the subjective standards of well-being.

    Recovery of recycled acrylonitrile-butadiene-styrene (ABS) through mixing with styrene-ethylene/butylene-styrene (SEBS) has been studied in this paper. To simulate recycled ABS, virgin ABS was processed through 5 cycles, at extreme processing temperatures, 220 degrees C and 260 degrees C. The virgin ABS, the virgin SEBS, the recycled ABS and the mixtures were mechanically, thermally and rheologically characterized after the various cycles of reprocessing in order to evaluate their correspondi...

    Staphylococcal enterotoxin B (SEB) is a pyrogenic exotoxin and a potent superantigen which causes massive T cell activation and cytokine secretion, leading to profound immunosuppression and morbidity. The inhibition of SEB-induced responses is thus considered a goal in the management of certain types of staphylococcal infections. Lactoferrin (LF) is a multi-functional glycoprotein with both bacteriostatic and bactericidal activities. In addition, LF is known to have potent immunomodulatory properties. Given the anti-microbial and anti-inflammatory properties of this protein, we hypothesized that LF can modulate T cell responses to SEB. Here, we report that bovine LF (bLF) was indeed able to attenuate SEB-induced proliferation, interleukin-2 production and CD25 expression by human leucocyte antigen (HLA)-DR4 transgenic mouse T cells. This inhibition was not due to bLF's iron-binding capacity, and could be mimicked by the bLF-derived peptide lactoferricin. Cytokine secretion by an engineered SEB-responsive human Jurkat T cell line and by peripheral blood mononuclear cells from healthy donors was also inhibited by bLF. These findings reveal a previously unrecognized property of LF in modulation of SEB-triggered immune activation and suggest a therapeutic potential for this naturally occurring protein during toxic shock syndrome.

    Pelowski et al. present a holistic framework within which the multiple processes underlying art viewing can be systematically organized [1]. The proposed model integrates a broad range of dynamic mechanisms, which can effectively account for empirical as well as humanistic perspectives on art perception. Particularly challenging is the final section of the article, where the authors draw a correspondence between behavioral and cognitive components and brain structures (as well as networks). Here, we comment on the implications of the Vienna Integrated Model of Art Perception for art therapy in clinical populations, particularly focusing on (1) expanding Pelowski et al.'s considerations of the Default Mode Network (DMN) into discussion of its relevance to mental diseases, and (2) elaborating on empathic resonance in aesthetic contexts and the capacity of art to build up empathic skills.

    Full Text Available Objective – To study high school teacher-librarians and whether their actions and reactions are aligned with their perception of the role they play in creating an information seeking and learning environment.Design – Triangulation qualitative research undertaken over a 16 month period (Fall 2005 – 2007.Setting – Six high school libraries in the Puget Sound region of the state of Washington, United States.Subjects – Six teacher-librarians, each with a minimum of ten years experience and classroom teachers and students. This sample represented the range of school sizes, the rural, urban, and suburban mix, and the range of significant socioeconomic conditions (qualification for subsidized lunch and English as an additional language in the region.Methods – Four interviews of one to two hours were held with each teacher-librarian during school hours. Initial interviews were recorded by hand and a set question protocol was used (and included in the appendix. Questions were asked about their professional background and training; their job duties, day to day activities and priorities; their perceptions as to how others (e.g., peers and administrators support the library; the goals of their library’s services; how students use the library; and their critical assessment of their role. Subsequent interviews were undertaken within two days of a classroom visit to the library and also followed a set protocol of questions (Appendix D. The second set of interviews was audio recorded and transcribed. Two classroom teachers from each school were interviewed for 30 minutes and audio recorded using a set interview protocol (Appendix C within two days of class participation in library instruction. Library observations ranging from two to three hours each occurred during a minimum of seven randomized times at each library. These observation sessions typically included class instructional sessions of thirty to ninety minutes. The observation protocols are described in an appendix to the study. Consistent note-taking, varying of observation times and days of week, use of triangulated methods, comparison of emergent themes with other studies, audio-taping interviews, inter-coder checks, analyzing data for observer effect, and a number of other approaches ensured validity. Kuhlthau’s theory of intermediation and Zone of Intervention was used as a theoretical framework to categorize the teacher-librarians’ perceptions of their roles and their observed activities. Harris and Dewdney’s principles of information seeking behaviour were used as an analytic framework to study the difference between the teacher-librarians’ perceptions of their roles and their observed practices. These five roles are organizer of information; expert in locating material; identifier and instructor of general sources; advisor of search strategy; and mediator in the process of constructing meaning (Kuhlthau.Main Results – The findings were framed in the six principles of information seeking (Harris & Dewdney and were presented through use of narrative captured in both the observations and interviews.Principle 1: Information needs arise from the help-seeker’s situation.The high school students in the library to complete assignments about which the teacher-librarians were not apprised; therefore the teacher-librarians were unable to assist the students in meeting information needs.Principle 2: The decision to seek help or not seek help is affected by many factors.Principle 3: People tend to seek information that is most accessible.Issues of control were the greatest barrier to students’ successful information seeking behaviour. In the environments observed, the greatest balance of power was within the control of the teachers, including when and if the students would have access to the library, and whether the teacher-librarian would be informed of the assignment. Within the library facility, the teacher-librarians demonstrated a high need for control and power over the students’ activities and behaviour, and the students themselves had almost no power.Principle 4: People tend to first seek help or information from interpersonal sources, especially from people like themselves.Principle 5: Information seekers expect emotional support.The interpersonal style of each teacher-librarian had an affect on the nature of the students’ information seeking behaviour. The narratives demonstrated how the practices of staff, in particular, those actions that set expectations for student behaviour, had an affect on the actual information seeking activities undertaken by students. Principle 6: People follow habitual patterns in seeking information. The narrative used to recount the unsuccessful instruction and research session demonstrates that unless students are convinced of the reasons why they should change their approach, they will not change habitual patterns in seeking information. Students use familiar sources and their familiarity is with Google and Wikipedia. In order for them to understand why these sources alone are not adequate, the students would need to experience a situation that demonstrates this and would cause them to reconsider their habitual patterns. Conclusion – Students were not exposed to teacher-librarian behaviours and roles that would enable the development of information literacy skills. The absence of collaboration between teachers and teacher-librarians was detrimental to the support of students in their assigned tasks. Students were not able to carry out information seeking practices with any autonomy and were given no meaningful reason or evidence as to why they should consider different practices. The failure to recognize that students have information habits that must be validated in order to assist them in changing or establishing new information seeking behaviours was problematic. The adolescents’ need for affective support was negated and had consequences that affected their information seeking experience. These teacher-librarians perceive that they fulfill roles in support of information literacy learning, but their behaviours and actions contradict this perception. Teacher-librarians must be able to identify, analyze and change their behaviours and actions in order to better enable student achievement.

    Full Text Available Objective – To better understand the lack of faculty participation in Cornell University’s DSpace institutional repository (IR, and to learn if this lack of participation is peculiar to Cornell or reflective of a larger trend in faculty non-participation in IRs.Design – Comparative analysis and interviews.Setting – Cornell University’s DSpace IR and sciences, social sciences, and humanities faculties; and DSpace installations at 7 other universities.Subjects – The DSpace IR at Cornell University and at 7 other locations. Eleven sciences, social sciences, and humanities faculty members at Cornell University.Methods – The authors analyzed data over a fifteen‐month period from Cornell’s DSpace IR to determine the total deposits, the types of objects deposited, the communities and collections that received deposits, the frequency of deposits, the IP addresses which made deposits, and how often objects in the IR were viewed. These data were compared to equivalent data taken from seven other IRs on all aspects except deposits from IP addresses and how oftenobjects were viewed. Finally, 11 Cornell faculty members from various departments in the sciences, social sciences, and humanities were interviewed over a two month period to provide context to the comparative analysis.Main results – At the time of the study, the IR at Cornell was organized into 193 communities of collections. These collections numbered 196, with 139 of them holding a combined total of 2646 objects: The other 57 collections were empty. While the IR as a whole showed steady growth, 77% of Cornell’s collections reflected a plateau growth pattern of primarily “one time deposits,” approximately 18% exhibited a stair‐step growth pattern of“periodic batch additions of material,” approximately 3% showed steady growth, and 1.4% were “uncatagorizable.” Five hundred nineteen unique IP addresses made deposits to Cornell’s IR over the course of the fifteen-month study, but 50% of these deposited only one object, and only 32 IP addresses deposited 10 or more objects. Of the other IRs studied, the lowest number of communities is zero and the highest is 390, the number of collections ranged from 10 to 282, and the number of objects ranged from 500 to 32,676. In most statistical categories, Cornell fell in the midrange. The two repositories with the fewest communities and collections – zero communities and 18 collections in one instance, and 6 and 10 in the other – are the only two with no empty collections. The repository with the most communities and collections also had the most empty collections (58%. The repository with the most objects was the one with zero communities and only 18 collections; and the repository with the fewest objects was the one with only 6 communities and 10collections. The third largest IR, with 3111 objects, had far and away the highest rate of steady growth (16.7%; while the IR with the most objects had the highest rate of stairstep growth (56.3%, and was the only IR to have a higher percentage of growth in any category other than plateau. Interviews with faculty indicated that they do not make deposits to IRs for a number of reasons. Faculty considered their primary audience to be their peers, so access to their scholarship was largely considered a “nonissue” as it was adequately provided through personal Web pages, subject repositories, or journal literature. Likewise, long-term preservation was not an overarching area of concern. The chief factors for not using an IR, however, all revolved around restrictions brought on by the academic reward system. Questions of copyright and whether depositing objects qualifies as publishing, thereby hindering efforts to publish in journals, were paramount, as were fears that depositing scholarship alongside less rigorous works in a catch-all IR would diminish the work and the reputation of the scholar by association. Hesitancy to make work available before ithad been certified and peer-reviewed was also a foremost concern. Conclusion – Although objects in Cornell’s DSpace are accessed both locally for items that are tied into the curriculum, and outside of the university for items that are of national (and international interest, the repository was not supported well by the faculty. The majority of the collections defined in Cornell’s IR were under populated, and what growth was evident arose primarily from deposits made by nonfaculty. The reasons for this were manifold, but centered primarily on the established culture of the academic reward system, which encourages publishing in recognized journals and does little to foster thoughts for long-term preservation or dissemination outside of a given scholar’s peer group. These issues were evident in faculty concerns that depositing materials in an IR might prevent later publication in a journal; the idea that depositing scholarship in a non‐vetted repository would diminish thatwork by association with less scholarly materials; the feeling in some fields that it would be irresponsible to provide access to any unfinished, non-vetted work; the thought that IRs are not sufficient to the task of certifying scholarship; and the concern that deposit in an IR might lead to plagiarism or the loss of initiative on unpublished ideas.

    The model presented here [1] is the latest in an evolving series of psychological models aimed at explaining the experience of art, first proposed by Leder and colleagues [2]. The aim of this new version is to ;explicitly connect early bottom-up, artwork-derived processing sequence and outputs to top-down, viewer-derived contribution to the processing sequence; [1, p. 5f & 6]. The ;meeting; of these two processing sequences, the authors contend, is crucial to the understanding of people's responses to art [sections 3.6ff & 4], and therefore the new model's principal motivation.

    In their target article published in this journal issue, Pelowski et al. [1] address the question of how humans experience, and respond to, visual art. They propose a multi-layered model of the representations and processes involved in assessing visual art objects that, furthermore, involves both bottom-up and top-down elements. Their model provides predictions for seven different outcomes of human aesthetic experience, based on few distinct features (schema congruence, self-relevance, and coping necessity), and connects the underlying processing stages to ;specific correlates of the brain; (a similar attempt was previously done for music by [2-4]). In doing this, the model aims to account for the (often profound) experience of an individual viewer in front of an art object.

    Aesthetic episodes, as all behavior, are situated. They take place as an interaction of person and situation variables [1]. There are different artistic and aesthetic domains that afford, in part, mutual mental processes, but also fundamentally different, e.g., modality-specific ones [2]. For the infinite number of possible aesthetic episodes a plethora of component processes can be selectively combined and dynamically configured. Following psychophysics' pragmatic dualism of mind and body, this results in dynamically configured (neuro-) biological networks subserving these mental processes [1]. These are, of course, also subject to evolutionary, biological, historical, cultural, and social change [1,3].

    The Vienna Integrated Model of Art Perception (VIMAP; [5]) is the most comprehensive model of the art experience today. The model incorporates bottom-up and top-down cognitive processes and accounts for different outcomes of the art experience, such as aesthetic evaluations, emotions, and physiological and neurological responses to art. In their presentation of the model, Pelowski et al. also present hypotheses that are amenable to empirical testing. These features make the VIMAP an ambitious model that attempts to explain how meaningful, complex, and profound aspects of the art experience come about, which is a significant extension of previous models of the art experience (e.g., [1-3,10]), and which gives the VIMAP good explanatory power.

    In this extensive and valuable theoretical article, Pelowski et al. propose a psychological architecture in art appreciation by introducing the concepts of early/bottom-up and relatively late/top-down stages. The former is dictated as automatic processing on perceptual features of visual images, while the latter comprises cognitive and evaluative processes where modulations from acquired knowledge and memories come into play with recurrent loops to form final experiences, as well as brain areas/networks which possibly have a role in each processing component [9].

    The proposal by the Vienna Integrated Model of Art Perception (Pelowski et al., [4]; VIMAP, hereafter) is a valuable and much needed attempt to summarize and understand the cognitive processes underlying art perception. Very important in their model is, as expected, to ascertain the psychological and brain processes correlated with the perception of beauty in art works. In this commentary we'll focus exclusively on the consideration of VIMAP's section 5, ;Model stages and corresponding areas of the brain.; We'll examine the evidence advanced by VIMAP in the section about brain networks related to the perception of art.

    In 20 patients with high-grade gliomas, we compared two methods of planning for volumetric-modulated arc therapy (VMAT): simultaneous integrated boost (SIB) vs. sequential boost (SEB). The investigation focused on the analysis of dose distributions in the target volumes and the organs at risk (OARs). After contouring the target volumes [planning target volumes (PTVs) and boost volumes (BVs)] and OARs, SIB planning and SEB planning were performed. The SEB method consisted of two plans: in the first plan the PTV received 50 Gy in 25 fractions with a 2-Gy dose per fraction. In the second plan the BV received 10 Gy in 5 fractions with a dose per fraction of 2 Gy. The doses of both plans were summed up to show the total doses delivered. In the SIB method the PTV received 54 Gy in 30 fractions with a dose per fraction of 1.8 Gy, while the BV received 60 Gy in the same fraction number but with a dose per fraction of 2 Gy. All of the OARs showed higher doses (D{sub max} and D{sub mean}) in the SEB method when compared with the SIB technique. The differences between the two methods were statistically significant in almost all of the OARs. Analysing the total doses of the target volumes we found dose distributions with similar homogeneities and comparable total doses. Our analysis shows that the SIB method offers advantages over the SEB method in terms of sparing OARs. (orig.)

    Full Text Available Background: Subsequent entry biologics (SEBs may soon be a reality in Canadian nephrology practice. Understanding the worldwide experience with these agents will be valuable to Canadian clinicians. Objectives: To compare the efficacy and safety data between SEBs used in nephrology practice and their reference biologic. Design: Systematic review. Sources of information: Ovid MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Review of Effects, Cochrane Central Register of Controlled Trials. Patients: Adult patients with chronic kidney disease (CKD. Methods: Our systematic review follows the process outlined by Cochrane Reviews. For efficacy data, all randomized controlled trials (RCTs, quasi-RCTs and observational trials in nephrology practice were included. For safety data, case series, case reports, review articles in nephrology practice and pharmacovigilance programs were included as well. Results: Only epoetin SEBs trials were published in the literature. Ten studies involving three different epoetin SEBs (epoetin zeta, HX575 and epoetin theta were included. The mean epoetin dose used did not differ significantly between the SEBs and the reference product. For epoetin zeta and epoetin theta, the mean hemoglobin levels achieved in the studies were similar between the SEBs and the reference epoetin. The HX 575 studies reported a mean absolute change in hemoglobin within the predefined equivalence margin, when compared with the reference biologic. In terms of safety data, 2 cases of pure-red-cell aplasia were linked to the subcutaneous administration of HX 575. Otherwise, the rate of adverse drug reactions was similar when epoetin SEBs were compared with the reference biologic. Limitations: Our analysis is limited by the paucity of information available on SEB use in nephrology with the exception of epoetin SEBs. Methodological flaw was found in one of the epoetin zeta studies which accounted for 45% of pooled

    Full Text Available Alfalfa (Medicago sativa L. is the oldest and the most important forage legume. It has been cultivated for forage longer than any other crop. Diversity indices provide information about community composition. Diversity indices are measured by species richness and species evenness therefore, it could give us more ecological information rather than a simple species list in the fields. During 2015-2016, aphids and ladybird beetle’s abundance and diversity were monitored in alfalfa fields of Yasouj. Samplings were conducted with 150 plants in the alfalfa fields from mid-May to mid-November. Species richness was measured using Shannon and Simpson indices. In this study, six aphids and five coccinellid species were collected and identified. Among the collected aphid species, Aphis fabae (Scopoli, 1763 and Therioaphis maculata (Buckton, 1899 were most abundant in the fields. For coccinellids, Coccinella septempunctata L. was the most abundant species. Highest aphid species diversity was observed on 17 May 2016.

  4. Winners and losers of state electricity boards reforms an organisational analysis

    Energy Technology Data Exchange (ETDEWEB)

    Ruet, J.

    2001-01-01

    The power sector in India is often described - in newspapers, in official reports, in reform programmes - as too 'poor' in money... and too 'rich' in politicians. These analyses hence propose corporatisation, un-bundling, setting up of regulatory commissions, as a vade mecum. The sole problem is that they have proved insufficient in improving the health of State Electricity Boards (SEBs). The ultimate tool, privatisation, has also been a deceptive one. This paper suggests that the above analyses should be balanced and completed with another element: the internal organisation itself of SEBs has to be questioned, which, surprisingly enough, is not done in the current reforms. This is not done because SEBs actually behave and are organised as administrations, whose objectives are different from those of a public enterprise. This is not done because consultants implicitly regard SEBs as inefficient enterprises. This paper thus enters into the black box of SEBs, and shows why and how the behaviour of its agents is rational, given the administrative system in which they are. It gives some practical ways to change this system, by developing on the 'enterprisation' of SEBs (turning them from bodies with an administration-style way of running into actual public enterprises), a concept which was coined from the reforms in Eastern Europe. But ultimately reforms are not undertaken per se. Their final aim is a better quality and availability to the people. Their impact on various categories of users and stakeholders can be discussed within this framework of enterprisation, to establish on which conditions reforms can be beneficial to everybody but the 'waste consumer'. This article is mainly based on repeated field inquires in Haryana, Andhra Pradesh and Orissa, at different stages of reform. In these States, the reform, far from precluding to analyse what are classical SEBs, brought to light some processes formerly in the dark. This

    Drugs such as linezolid that inhibit bacterial protein synthesis may be beneficial in treating infections caused by toxigenic Staphylococcus aureus. As protein synthesis inhibitors have no effect on preformed toxins, neutralization of pathogenic exotoxins with anti-toxin antibodies may be beneficial in conjunction with antibacterial therapy. Herein, we evaluated the efficacy of human-mouse chimeric high-affinity neutralizing anti-staphylococcal enterotoxin B (SEB) antibodies in the treatment of experimental pneumonia caused by SEB-producing S. aureus. Since HLA class II transgenic mice mount a stronger systemic immune response following challenge with SEB and are more susceptible to SEB-induced lethal toxic shock than conventional mice strains, HLA-DR3 transgenic mice were used. Lethal pneumonia caused by SEB-producing S. aureus in HLA-DR3 transgenic mice was characterized by robust T cell activation and elevated systemic levels of several pro-inflammatory cytokines and chemokines. Prophylactic administration of a single dose of linezolid 30 min prior to the onset of infection attenuated the systemic inflammatory response and protected from mortality whereas linezolid administered 60 min after the onset of infection failed to confer significant protection. Human-mouse chimeric high-affinity neutralizing anti-SEB antibodies alone, but not polyclonal human IgG, mitigated this response and protected from death when administered immediately after initiation of infection. Further, anti-SEB antibodies as well as intact polyclonal human IgG, but not its Fab or Fc fragments, protected from lethal pneumonia when followed with linezolid therapy 60 min later. In conclusion, neutralization of superantigens with high-affinity antibodies may have beneficial effects in pneumonia.

  16. Subinhibitory concentrations of thymol reduce enterotoxins A and B and alpha-hemolysin production in Staphylococcus aureus isolates.

    Directory of Open Access Journals (Sweden)

    Jiazhang Qiu

    Full Text Available BACKGROUND: Targeting bacterial virulence factors is now gaining interest as an alternative strategy to develop new types of anti-infective agents. It has been shown that thymol, when used at low concentrations, can inhibit the TSST-1 secretion in Staphylococcus aureus. However, there are no data on the effect of thymol on the production of other exotoxins (e.g., alpha-hemolysin and enterotoxins by S. aureus. METHODOLOGY/PRINCIPAL FINDINGS: Secretion of alpha-hemolysin, SEA and SEB in both methicillin-sensitive and methicillin-resistant S. aureus isolates cultured with graded subinhibitory concentrations of thymol was detected by immunoblot analysis. Hemolysin and tumor necrosis factor (TNF release assays were performed to elucidate the biological relevance of changes in alpha-hemolysin, SEA and SEB secretion induced by thymol. In addition, the influence of thymol on the transcription of hla, sea, and seb (the genes encoding alpha-hemolysin, SEA and SEB, respectively was analyzed by quantitative RT-PCR. Thymol inhibited transcription of hla, sea and seb in S. aureus, resulting in a reduction of alpha-hemolysin, SEA and SEB secretion and, thus, a reduction in hemolytic and TNF-inducing activities. CONCLUSIONS/SIGNIFICANCE: Subinhibitory concentrations of thymol decreased the production of alpha-hemolysin, SEA and SEB in both MSSA and MRSA in a dose-dependent manner. These data suggest that thymol may be useful for the treatment of S. aureus infections when used in combination with beta-lactams and glycopeptide antibiotics, which induce expression of alpha-hemolysin and enterotoxins at subinhibitory concentrations. Furthermore, the structure of thymol may potentially be used as a basic structure for development of drugs aimed against these bacterial virulence factors.

    The ability of remote sensing-based surface energy balance (SEB) models to track water stress in rain-fed switchgrass (Panicum virgatum L.) has not been explored yet. In this paper, the theoretical framework of crop water stress index (CWSI; 0 = extremely wet or no water stress condition and 1 = extremely dry or no transpiration) was utilized to estimate CWSI in rain-fed switchgrass using Landsat-derived evapotranspiration (ET) from five remote sensing based single-source SEB models, namely Surface Energy Balance Algorithm for Land (SEBAL), Mapping ET with Internalized Calibration (METRIC), Surface Energy Balance System (SEBS), Simplified Surface Energy Balance Index (S-SEBI), and Operational Simplified Surface Energy Balance (SSEBop). CWSI estimates from the five SEB models and a simple regression model that used normalized difference vegetation index (NDVI), near-surface temperature difference, and measured soil moisture (SM) as covariates were compared with those derived from eddy covariance measured ET (CWSIEC) for the 32 Landsat image acquisition dates during the 2011 (dry) and 2013 (wet) growing seasons. Results indicate that most SEB models can predict CWSI reasonably well. For example, the root mean square error (RMSE) ranged from 0.14 (SEBAL) to 0.29 (SSEBop) and the coefficient of determination (R2) ranged from 0.25 (SSEBop) to 0.72 (SEBAL), justifying the added complexity in CWSI modeling as compared to results from the simple regression model (R2 = 0.55, RMSE = 0.16). All SEB models underestimated CWSI in the dry year but the estimates from SEBAL and S-SEBI were within 7% of the mean CWSIEC and explained over 60% of variations in CWSIEC. In the wet year, S-SEBI mostly overestimated CWSI (around 28%), while estimates from METRIC, SEBAL, SEBS, and SSEBop were within 8% of the mean CWSIEC. Overall, SEBAL was the most robust model under all conditions followed by METRIC, whose performance was slightly worse and better than SEBAL in dry and wet years

  18. Colorimetric determination of staphylococcal enterotoxin B via DNAzyme-guided growth of gold nanoparticles

    The authors describe a colorimetric method for the determination of the staphylococcal enterotoxin B (SEB) that also allows for visual readout. The assay is based on the growth of gold nanoparticles (AuNPs) mediated by a hemin/G-quadruplex DNAzyme which generates a color change from red to blue in the presence of SEB. The method is enzyme-free and does not require a label. The kinetics of the formation of the AuNPs is controlled by the hemin/G-quadruplex DNAzyme and this is key to the signal generation mechanism. In the presence of SEB, the reactions between aptamer and target modulated the amount of single probe G strands that form DNAzyme capable of consuming hydrogen peroxide. The growth process of AuNPs is influenced by the resulting concentration of H 2 O 2 and leads to the color change. Under optimal conditions, a linear relationship exists between absorbance and SEB concentration in the range from 0.1 to 500 pg·mL -1 which covers the clinically relevant range. In case of visual detection, the lower limit of detection is 1 pg·mL −1 . The assay described here is sensitive, comparably inexpensive and can detect SEB rapidly without the need for sophisticated equipment. In our perception, the method has a wide scope in that it may be adapted to various nucleic acids, proteins and other biomolecules if respective aptamers are available. (author)

  19. Tuning antiferromagnetic exchange interaction for spontaneous exchange bias in MnNiSnSi system

    2017-12-01

    Based on almost all the data from the literature on spontaneous exchange bias (SEB), it is expected that the system will show SEB if it meets two conditions simultaneously: (i) there are the coexistence and competition of antiferromagnetic (AFM) and ferromagnetic (FM) interactions and (ii) AFM interaction should dominate but not be too strong in this competition. In order to verify this view, a systematic study on SEB has been performed in this work. Mn50Ni40Sn10 with strong FM interaction and without SEB is chosen as the mother composition, and the negative chemical pressure is introduced by the substitution of Sn by Si to enhance AFM interaction. It is found that a long-range FM ordering window is closed, and a long-range AFM ordering window is opened. As a result, SEB is triggered and a continuous tuning of the spontaneous exchange bias field (HSEB) from 0 Oe to 1300 Oe has been realized in a Mn50Ni40Sn10-xSix system by the enhanced AFM interaction.

    2018-03-01

    We present a single-event burnout (SEB) hardened planar power MOSFET with partially widened trench sources by three-dimensional (3D) numerical simulation. The advantage of the proposed structure is that the work of the parasitic bipolar transistor inherited in the power MOSFET is suppressed effectively due to the elimination of the most sensitive region (P-well region below the N+ source). The simulation result shows that the proposed structure can enhance the SEB survivability significantly. The critical value of linear energy transfer (LET), which indicates the maximum deposited energy on the device without SEB behavior, increases from 0.06 to 0.7 pC/μm. The SEB threshold voltage increases to 120 V, which is 80% of the rated breakdown voltage. Meanwhile, the main parameter characteristics of the proposed structure remain similar with those of the conventional planar structure. Therefore, this structure offers a potential optimization path to planar power MOSFET with high SEB survivability for space and atmospheric applications.

    Full Text Available Development of a rapid field test is needed capable of determining if field supplies of water are safe to drink by the warfighter during a military operation. The present study sought to assess the effectiveness of handheld assays (HHAs in detecting ricin and Staphylococcal Enterotoxin B (SEB in water. Performance of HHAs was evaluated in formulated tap water with and without chlorine, reverse osmosis water (RO with chlorine, and RO with bromine. Each matrix was prepared, spiked with ricin or SEB at multiple concentrations, and then loaded onto HHAs. HHAs were allowed to develop and then read visually. Limits of detection (LOD were determined for all HHAs in each water type. Both ricin and SEB were detected by HHAs in formulated tap water at or below the suggested health effect levels of 455 ng/mL and 4.55 ng/mL, respectively. However, in brominated or chlorinated waters, LODs for SEB increased to approximately 2,500 ng/mL. LODs for ricin increased in chlorinated water, but still remained below the suggested health effect level. In brominated water, the LOD for ricin increased to approximately 2,500 ng/mL. In conclusion, the HHAs tested were less effective at detecting ricin and SEB in disinfected water, as currently configured.

    2012-01-01

    In this work, single event effects and total ionizing dose effects of typical VDMOSFET irradiated by 60 Co γ-rays and 252 Cf source were studied. The single event burnout and single event gate rupture (SEB/SEGR) effects were investigated, and the relationship between drain-source breakdown voltage and ionizing dose was obtained. The results showed that the VDMOSFET devices were sensitive to SEB and SEGR, and measures to improve their resistance to SEB and SEGR should be considered seriously for their space applications. The drain-source breakdown voltage was sensitive to total ionizing dose effects as the threshold voltage. In assessing the devices' resistance to the total ionizing dose effects, both the threshold voltage and the drain-source breakdown voltage should be taken into account. (authors)

  3. Simulation study on single event burnout in linear doping buffer layer engineered power VDMOSFET

    2016-01-01

    The addition of a buffer layer can improve the device's secondary breakdown voltage, thus, improving the single event burnout (SEB) threshold voltage. In this paper, an N type linear doping buffer layer is proposed. According to quasi-stationary avalanche simulation and heavy ion beam simulation, the results show that an optimized linear doping buffer layer is critical. As SEB is induced by heavy ions impacting, the electric field of an optimized linear doping buffer device is much lower than that with an optimized constant doping buffer layer at a given buffer layer thickness and the same biasing voltages. Secondary breakdown voltage and the parasitic bipolar turn-on current are much higher than those with the optimized constant doping buffer layer. So the linear buffer layer is more advantageous to improving the device's SEB performance. (paper)

    The aim of this paper is to investigate the stabilization of polypropylene in the poly (styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS)/polypropylene (PP) blends under irradiation with respect to PP. The PP films, SEBS/PP films were subjected to electron beam irradiation and characterized by wide angle X-ray diffraction (WAXD), differential scanning calorimetry (DSC), gel permeation chromatography (GPC), and dynamic mechanical thermal analysis (DMTA). It demonstrated that upon irradiation, the molecular weight of PP had a pronounced decrease due to the major chain scission, and the minor chain cross-linking or chain branching occurred at the higher irradiation dose. Stabilization of PP was improved in the presence of SEBS, exhibiting an enhanced irradiation resistance.

    Hyaluronic acid (HA) is an important component of extracellular matrix (ECM) in many tissues, providing a hemocompatible and supportive environment for cell growth. In this study, glycidyl methacrylate-hyaluronic acid (GMHA) was first synthesized and verified by proton nuclear magnetic resonance ((1)H NMR) spectroscopy. GMHA was then grafted to the surface of biomedical elastomer poly (styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) via an UV-initiated polymerization, monitored by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS). The further improvement of biocompatibility of the GMHA-modified SEBS films was assessed by platelet adhesion experiments and in vitro response of murine osteoblastic cell line MC-3T3-E1 with the virgin SEBS surface as the reference. It showed that the surface modification with HA strongly resisted platelet adhesion whereas improved cell-substrate interactions. Copyright © 2012 Elsevier B.V. All rights reserved.

    Superantigens are immune-stimulatory toxins produced by Staphylococcus aureus, which are able to interact with host immune receptors to induce a massive release of cytokines, causing toxic shock syndrome and possibly death. In this article, we present the x-ray structure of staphylococcal enterotoxin B (SEB) in complex with its receptors, the TCR and MHC class II, forming a ternary complex. The structure, in combination with functional analyses, clearly shows how SEB adopts a wedge-like position when binding to the β-chain of TCR, allowing for an interaction between the α-chain of TCR and MHC. Furthermore, the binding mode also circumvents contact between TCR and the peptide presented by MHC, which enables SEB to initiate a peptide-independent activation of T cells.

  8. Staphylococcal Superantigens Spark Host-Mediated Danger Signals

    Full Text Available Staphylococcal enterotoxin B (SEB of Staphylococcus aureus, and related superantigenic toxins produced by myriad microbes, are potent stimulators of the immune system causing a variety of human diseases from transient food poisoning to lethal toxic shock. These protein toxins bind directly to specific V regions of T-cell receptors (TCR and major histocompatibility complex (MHC class II on antigen-presenting cells, resulting in hyperactivation of T lymphocytes and monocytes / macrophages. Activated host cells produce excessive amounts of proinflammatory cytokines and chemokines, especially tumor necrosis factor α, interleukin 1 (IL-1, IL-2, interferon γ (IFNγ, and macrophage chemoattractant protein 1 causing clinical symptoms of fever, hypotension, and shock. Because of superantigen-induced T cells skewed towards TH1 helper cells, and the induction of proinflammatory cytokines, superantigens can exacerbate autoimmune diseases. Upon TCR / MHC ligation, pathways induced by superantigens include the mitogen-activated protein kinase cascades and cytokine receptor signaling, resulting in activation of NFκB and the phosphoinositide 3-kinase / mammalian target of rapamycin pathways. Various mouse models exist to study SEB-induced shock including those with potentiating agents, transgenic mice and an SEB-only model. However, therapeutics to treat toxic shock remain elusive as host response genes central to pathogenesis of superantigens have only been identified recently. Gene profiling of a murine model for SEB-induced shock reveals novel molecules upregulated in multiple organs not previously associated with SEB-induced responses. The pivotal genes include intracellular DNA / RNA sensors, apoptosis / DNA damage-related molecules, immunoproteasome components, as well as anti-viral and IFN-stimulated genes. The host-wide induction of these, and other, anti-microbial defense genes provide evidence that SEB elicits danger signals resulting in multi

    Increased life expectancy has promoted research on healthy aging. Aging is accompanied by increased non-specific immune activation (inflammaging) which favors the appearance of several disorders. Here, we study whether dietary supplementation with spray-dried animal plasma (SDP), which has been shown to reduce the activation of gut-associated lymphoid tissue (GALT) in rodents challenged by S. aureus enterotoxin B (SEB), and can also prevent the effects of aging on immune system homeostasis. We first characterized GALT in a mouse model of accelerated senescence (SAMP8) at different ages (compared to mice resistant to accelerated senescence; SAMR1). Second, we analyzed the SDP effects on GALT response to an SEB challenge in SAMP8 mice. In GALT characterization, aging increased the cell number and the percentage of activated Th lymphocytes in mesenteric lymph nodes and Peyer's patches (all, p < 0.05), as well as the expression of IL-6 and TNF-α in intestinal mucosa (both, p < 0.05). With respect to GALT response to the SEB challenge, young mice showed increased expression of intestinal IL-6 and TNF-α, as well as lymphocyte recruitment and activation (all, p < 0.05). However, the immune response of senescent mice to the SEB challenge was weak, since SEB did not change cell recruitment or the percentage of activated Th lymphocytes. Mice supplemented with SDP showed improved capacity to respond to the SEB challenge, similar to the response of the young mice. These results indicate that senescent mice have an impaired mucosal immune response characterized by unspecific GALT activation and a weak specific immune response. SDP supplementation reduces non-specific basal immune activation, allowing for the generation of specific responses.

    Lund, Magnus; Stiegler, Christian; Abermann, Jakob

    2017-01-01

    The surface energy balance (SEB) is essential for understanding the coupled cryosphere–atmosphere system in the Arctic. In this study, we investigate the spatiotemporal variability in SEB across tundra, snow and ice. During the snow-free period, the main energy sink for ice sites is surface melt....... For tundra, energy is used for sensible and latent heat flux and soil heat flux leading to permafrost thaw. Longer snow-free period increases melting of the Greenland Ice Sheet and glaciers and may promote tundra permafrost thaw. During winter, clouds have a warming effect across surface types whereas during...

    2009-06-01

    This work analyzes the thermal and mechanical effects arising in a power Diffusion Metal Oxide Semiconductor (DMOS) during a Single Event Burnout (SEB) process. For studying these effects we propose a more detailed simulation structure than the previously used by other authors, solving the mathematical models by means of the Finite Element Method. We use a cylindrical heat generation region, with 5 W, 10 W, 50 W and 100 W for emulating the thermal phenomena occurring during SEB processes, avoiding the complexity of the mathematical treatment of the ion-semiconductor interaction.

    Directory of Open Access Journals (Sweden)

    Francois P. Viljoen

    2013-03-01

    Full Text Available Righteousness is an important term in the first gospel and has a significant concentration in the Sermon on the Mount. The argument in this article is that the first gospel has a community building function. Matthew intentionally uses the word ‘righteousness’ in the Sermon on the Mount as an instrument to define the identity of his community. Though righteousness can be used in a soteriological sense, it is argued that Matthew mainly uses it in an ethical sense. By righteousness Matthew refers to the proper behavioural norms and attitudes for his community. Commitment to Jesus forms the central focus of the community’s identity. Their discipleship is demonstrated by doing the will of God as defined and interpreted by Jesus. Doing the will of God in such a manner is what Matthew regards as the distinguishing mark of this community. Thus they would surpass the righteousness of the scribes and Pharisees.

    Science.gov (United States)

    2011-01-01

    Background Considering that the costs of cellulases and hemicellulases contribute substantially to the price of bioethanol, new studies aimed at understanding and improving cellulase efficiency and productivity are of paramount importance. Aspergillus niger has been shown to produce a wide spectrum of polysaccharide hydrolytic enzymes. To understand how to improve enzymatic cocktails that can hydrolyze pretreated sugarcane bagasse, we used a genomics approach to investigate which genes and pathways are transcriptionally modulated during growth of A. niger on steam-exploded sugarcane bagasse (SEB). Results Herein we report the main cellulase- and hemicellulase-encoding genes with increased expression during growth on SEB. We also sought to determine whether the mRNA accumulation of several SEB-induced genes encoding putative transporters is induced by xylose and dependent on glucose. We identified 18 (58% of A. niger predicted cellulases) and 21 (58% of A. niger predicted hemicellulases) cellulase- and hemicellulase-encoding genes, respectively, that were highly expressed during growth on SEB. Conclusions Degradation of sugarcane bagasse requires production of many different enzymes which are regulated by the type and complexity of the available substrate. Our presently reported work opens new possibilities for understanding sugarcane biomass saccharification by A. niger hydrolases and for the construction of more efficient enzymatic cocktails for second-generation bioethanol.

  9. Triggering Mechanism for Neutron Induced Single-Event Burnout in Power Devices

    Science.gov (United States)

    Shoji, Tomoyuki; Nishida, Shuichi; Hamada, Kimimori

    2013-04-01

    Cosmic ray neutrons can trigger catastrophic failures in power devices. It has been reported that parasitic transistor action causes single-event burnout (SEB) in power metal-oxide-semiconductor field-effect transistors (MOSFETs) and insulated gate bipolar transistors (IGBTs). However, power diodes do not have an inherent parasitic transistor. In this paper, we describe the mechanism triggering SEB in power diodes for the first time using transient device simulation. Initially, generated electron-hole pairs created by incident recoil ions generate transient current, which increases the electron density in the vicinity of the n-/n+ boundary. The space charge effect of the carriers leads to an increase in the strength of the electric field at the n-/n+ boundary. Finally, the onset of impact ionization at the n-/n+ boundary can trigger SEB. Furthermore, this failure is closely related to diode secondary breakdown. It was clarified that the impact ionization at the n-/n+ boundary is a key point of the mechanism triggering SEB in power devices.

  10. An Updated Perspective of Single Event Gate Rupture and Single Event Burnout in Power MOSFETs

    Science.gov (United States)

    Titus, Jeffrey L.

    2013-06-01

    Studies over the past 25 years have shown that heavy ions can trigger catastrophic failure modes in power MOSFETs [e.g., single-event gate rupture (SEGR) and single-event burnout (SEB)]. In 1996, two papers were published in a special issue of the IEEE Transaction on Nuclear Science [Johnson, Palau, Dachs, Galloway and Schrimpf, “A Review of the Techniques Used for Modeling Single-Event Effects in Power MOSFETs,” IEEE Trans. Nucl. Sci., vol. 43, no. 2, pp. 546-560, April. 1996], [Titus and Wheatley, “Experimental Studies of Single-Event Gate Rupture and Burnout in Vertical Power MOSFETs,” IEEE Trans. Nucl. Sci., vol. 43, no. 2, pp. 533-545, Apr. 1996]. Those two papers continue to provide excellent information and references with regard to SEB and SEGR in vertical planar MOSFETs. This paper provides updated references/information and provides an updated perspective of SEB and SEGR in vertical planar MOSFETs as well as provides references/information to other device types that exhibit SEB and SEGR effects.

  15. On elastic limit margins for earthquake design

    International Nuclear Information System (INIS)

    Buchhardt, F.; Matthees, W.; Magiera, G.

    1987-01-01

    In the Federal Republic of Germany KTA rule 2201 being the basis for the design of nuclear power plants against seismic events is now under discussion for revisions. One of the main demands to modify KTA rule 2201 consists in cancelling the existing design philosophy, i.e. design against an operating basis earthquake (AEB) as well as against a safe shutdown earthquake (SEB). When using the present rule the 'lower' earthquake (AEB) can become design-predominant, since for AEB and SEB different types of load cases are to be superimposed with different safety factors. The scope of this study is to quantify by parametric analyses so-called 'elastic bearing capacity limit margins' for seismic events; hereby different seismic input criteria - conventional as well as recently proposed are taken into account to investigate the influence of eventual modifications in seismic design philosophy. This way a relation between AEB and SEB has to be defined so that SEB is just still predominant for the design while AEB still will yield to elastic behaviour. The study covers all German site conditions

    Mondal, Bhairab; N, Bhavanashri; Ramlal, Shylaja; Kingston, Joseph

    2018-02-14

    In the present study, a colorimetric DNAzymes biosensor strategy was devised in combination with immunomagnetic separation for rapid and easy detection of enterotoxin B harboring Staphylococcus aureus from food and clinical samples. The method employs immunocapture of S. aureus and amplification of seb gene by DNAzyme complementary sequence integrated forward primer and with specific reverse primer. The DNAzyme sequence integrated dsDNA PCR products when treated with hemin and TMB (3,3',5,5'-tetramethylbenzidine) in the presence of H 2 O 2 produce colorimetric signal. A linear relationship of optical signal with the initial template of seb was obtained which could be monitored by visually or spectrophotrometrically for qualitative and quantitative detection. The limit of detection for the assay was approximately 10 2 CFU/mL of seb gene harboring target. This method is convenient compared to gel based and ELISA systems. Further, spiking studies and analysis on natural samples emphasized the robustness and applicability of developed method. Altogether, the established assay could be a reliable alternative, low-cost, viable detection tool for the routine investigation of seb from food and clinical sources.

    Ritima Banerjee

    2018-04-01

    Full Text Available The present work is a novel attempt to understand the microstructure of styrene-ethylene-butylene-styrene (SEBS/polystyrene (PS blends not only through morphological studies, but also thermal, mechanical and rheological characterizations. SEBS/PS blends containing 10, 30 and 50 wt % PS were processed in a micro-compounder and characterized. Scanning electron microscopy (SEM studies, with selective staining of the PS phase, revealed the presence of PS as nanometer-sized domains, as well as phase-separated micrometer-sized aggregates. Blends with 30 and 50 wt % PS exhibited a fibrillar microstructure, obeying Hirsch’s model of short fiber composites. A remarkable increase in glass transition temperature indicated a strong interaction of the fibrils with SEBS. All blends showed two modes of relaxation corresponding to the two phases. A single mode of relaxation of the PS phase has been attributed to combined effects of the partial miscibility of the added PS, along with the interaction of the fibrils with SEBS. The long relaxation time of the elastomeric phase indicated the tendency of these materials to undergo time-dependent shrinkage in secondary processing operations. An increase in PS content resulted in the lowering of the shear viscosity and energy requirement for mixing, indicating the ease of processing.

    Full Text Available Abstract Background Considering that the costs of cellulases and hemicellulases contribute substantially to the price of bioethanol, new studies aimed at understanding and improving cellulase efficiency and productivity are of paramount importance. Aspergillus niger has been shown to produce a wide spectrum of polysaccharide hydrolytic enzymes. To understand how to improve enzymatic cocktails that can hydrolyze pretreated sugarcane bagasse, we used a genomics approach to investigate which genes and pathways are transcriptionally modulated during growth of A. niger on steam-exploded sugarcane bagasse (SEB. Results Herein we report the main cellulase- and hemicellulase-encoding genes with increased expression during growth on SEB. We also sought to determine whether the mRNA accumulation of several SEB-induced genes encoding putative transporters is induced by xylose and dependent on glucose. We identified 18 (58% of A. niger predicted cellulases and 21 (58% of A. niger predicted hemicellulases cellulase- and hemicellulase-encoding genes, respectively, that were highly expressed during growth on SEB. Conclusions Degradation of sugarcane bagasse requires production of many different enzymes which are regulated by the type and complexity of the available substrate. Our presently reported work opens new possibilities for understanding sugarcane biomass saccharification by A. niger hydrolases and for the construction of more efficient enzymatic cocktails for second-generation bioethanol.

  20. Comparison of Four Different Energy Balance Models for Estimating Evapotranspiration in the Midwestern United States

    Directory of Open Access Journals (Sweden)

    Ramesh K. Singh

    2015-12-01

    Full Text Available The development of different energy balance models has allowed users to choose a model based on its suitability in a region. We compared four commonly used models—Mapping EvapoTranspiration at high Resolution with Internalized Calibration (METRIC model, Surface Energy Balance Algorithm for Land (SEBAL model, Surface Energy Balance System (SEBS model, and the Operational Simplified Surface Energy Balance (SSEBop model—using Landsat images to estimate evapotranspiration (ET in the Midwestern United States. Our models validation using three AmeriFlux cropland sites at Mead, Nebraska, showed that all four models captured the spatial and temporal variation of ET reasonably well with an R2 of more than 0.81. Both the METRIC and SSEBop models showed a low root mean square error (<0.93 mm·day−1 and a high Nash–Sutcliffe coefficient of efficiency (>0.80, whereas the SEBAL and SEBS models resulted in relatively higher bias for estimating daily ET. The empirical equation of daily average net radiation used in the SEBAL and SEBS models for upscaling instantaneous ET to daily ET resulted in underestimation of daily ET, particularly when the daily average net radiation was more than 100 W·m−2. Estimated daily ET for both cropland and grassland had some degree of linearity with METRIC, SEBAL, and SEBS, but linearity was stronger for evaporative fraction. Thus, these ET models have strengths and limitations for applications in water resource management.

  13. Fracture mechanics characterisation of the WWER-440 reactor pressure vessel beltline welding seam of Greifswald unit 8

    2008-01-01

    WWER-440 second generation (V-213) reactor pressure vessels (RPV) were produced by IZHORA in Russia and by SKODA in the former Czechoslovakia. The surveillance Charpy-V and fracture mechanics SE(B) specimens of both producers have different orientations. The main difference is the crack extension direction which is through the RPV thickness and circumferential for ISHORA and SKODA RPV, respectively. In particular for the investigation of weld metal from multilayer submerged welding seams the crack extension direction is of importance. Depending on the crack extension direction in the specimen there are different welding beads or a uniform structure along the crack front. The specimen orientation becomes more important when the fracture toughness of the weld metal is directly determined on surveillance specimens according to the Master Curve (MC) approach as standardised in the ASTM Standard Test Method E1921. This approach was applied on weld metal of the RPV beltline welding seam of Greifswald Unit 8 RPV. Charpy size SE(B) specimens from 13 locations equally spaced over the thickness of the welding seam were tested. The specimens are in TL and TS orientation. The fracture toughness values measured on the SE(B) specimens with both orientations follow the course of the MC. Nearly all values lie within the fracture toughness curves for 5% and 95% fracture probability. There is a strong variation of the reference temperature T 0 though the thickness of the welding seam, which can be explained with structural differences. The scatter is more pronounced for the TS SE(B) specimens. It can be shown that specimens with TS and TL orientation in the welding seam have a differentiating and integrating behaviour, respectively. The statistical assumptions behind the MC approach are valid for both specimen orientations even if the structure is not uniform along the crack front. By comparison crack extension, JR, curves measured on SE(B) specimens with TL and TS orientation show

    In 20 patients with high-grade gliomas, we compared two methods of planning for volumetric-modulated arc therapy (VMAT): simultaneous integrated boost (SIB) vs. sequential boost (SEB). The investigation focused on the analysis of dose distributions in the target volumes and the organs at risk (OARs). After contouring the target volumes [planning target volumes (PTVs) and boost volumes (BVs)] and OARs, SIB planning and SEB planning were performed. The SEB method consisted of two plans: in the first plan the PTV received 50 Gy in 25 fractions with a 2-Gy dose per fraction. In the second plan the BV received 10 Gy in 5 fractions with a dose per fraction of 2 Gy. The doses of both plans were summed up to show the total doses delivered. In the SIB method the PTV received 54 Gy in 30 fractions with a dose per fraction of 1.8 Gy, while the BV received 60 Gy in the same fraction number but with a dose per fraction of 2 Gy. All of the OARs showed higher doses (Dmax and Dmean) in the SEB method when compared with the SIB technique. The differences between the two methods were statistically significant in almost all of the OARs. Analysing the total doses of the target volumes we found dose distributions with similar homogeneities and comparable total doses. Our analysis shows that the SIB method offers advantages over the SEB method in terms of sparing OARs.

    Staphylococcus aureus (S. aureus) can cause mastitis in cattle and, therefore, can be present in milk. This study was undertaken to determine the prevalence of coagulase positive S. aureus and its enterotoxin genes sea, seb, and sec in isolates recovered from raw milk, feta cheese, and human hand swabs of milk and cheese handlers in Beni-Suef province, Egypt. A total of 100 samples of raw milk and 50 samples of pasteurized-milk feta cheese were collected. In addition, 50 hand swabs from milk handlers and 25 hand swabs from cheese handlers were examined for the presence of coagulase positive S. aureus. The isolates were characterized by multiplex PCR for detection of sea, seb, and sec genes, and for resistance to 5 classes of commonly used antibiotics. Twelve (12/100), 12 (6/50), and 17% (13/75) of milk, cheese, and hand swab samples, respectively, were positive for coagulase positive S. aureus. One isolate was obtained from each positive sample (31 isolates), and none contained genes for SEA or SEC production. Twenty-five percent, 33%, and 31%, respectively, of the isolates contained the genes for SEB, resulting in 3%, 4%, and 5% of samples being positive for toxin producing coagulase positive S. aureus, respectively. At least one isolate was resistant to each of the antibiotics tested. Despite the low potential for SEB production shown, preventative measures, such as maintenance of the cold-chain and good hygienic practices should be implemented to further reduce the potential risk to public health from SEB, and to reduce the spread of antimicrobial resistance. © 2015 Institute of Food Technologists®

    2009-12-01

    Banana fiber (BaF)-filled composites based on high density polyethylene (HDPE)/Nylon-6 blends were prepared via a two-step extrusion method. Maleic anhydride grafted styrene/ethylene-butylene/styrene triblock polymer (SEBS-g-MA) and maleic anhydride grafted polyethylene (PE-g-MA) were used to enhance impact performance and interfacial bonding between BaF and the resins. Mechanical, crystallization/melting, thermal stability, water absorption, and morphological properties of the composites were investigated. In the presence of SEBS-g-MA, better strengths and moduli were found for HDPE/Nylon-6 based composites compared with corresponding HDPE based composites. At a fixed weight ratio of PE-g-MA to BaF, an increase of BaF loading up to 48.2 wt.% led to a continuous improvement in moduli and flexural strength of final composites, while impact toughness was lowered gradually. Predicted tensile modulus by the Hones-Paul model for three-dimensional random fiber orientation agreed well with experimental data at the BaF loading of 29.3 wt.%. However, the randomly-oriented fiber models underestimated experimental data at higher fiber levels. It was found that the presence of SEBS-g-MA had a positive influence on reinforcing effect of the Nylon-6 component in the composites. Thermal analysis results showed that fractionated crystallization of the Nylon-6 component in the composites was induced by the addition of both SEBS-g-MA and PE-g-MA. Thermal stability of both composite systems differed slightly, except an additional decomposition peak related to the minor Nylon-6 for the composites from the HDPE/Nylon-6 blends. In the presence of SEBS-g-MA, the addition of Nylon-6 and increased BaF loading level led to an increase in the water absorption value of the composites.

    2004-01-28

    Solution calorimetry has been used in a number of varying applications within pharmaceutical research as a technique for the physical characterisation of pharmaceutical materials, such as quantifying small degrees of amorphous content, identifying polymorphs and investigating interactions between drugs and carbohydrates or proteins and carbohydrates. A calibration test procedure is necessary to validate the instrumentation; a few of the suggested calibration reactions are the enthalpies of solution associated with dissolving Tris in 0.1 M HCl or NaCl, KCl or propan-1-ol in water. In addition, there are a number of different methods available to determine enthalpies of solution from the experimental data provided by the calorimeter, for example, the Regnault-Pfaundler's method, a graphical extrapolation based on the Dickinson method, or a manual integration-based method. Thus, the aim of the study was to investigate how each of these methods influences the values for the enthalpy of solution. Experiments were performed according to the method outlined by Hogan and Buckton [Int. J. Pharm. 207 (2000) 57] using KCl (samples of 50, 100 and 200 mg), Tris and sucrose as calibrants. For all three materials the manual integration method was found to be the most consistent with the KCl in water (sample mass of 200 mg) being the most precise. Thus, this method is recommended for the validation of solution calorimeters.
