    Excellent surface passivation and anti-reflection properties of double-stack layers is a prerequisite for high efficiency of n-type c-Si solar cells. The high positive fixed charge (Q f) density of N-rich hydrogenated amorphous silicon nitride (a-SiNx:H) films plays a poor role in boron emitter passivation. The more the refractive index ( n ) of a-SiNx:H is decreased, the more the positive Q f of a-SiNx:H is increased. Hydrogenated amorphous silicon oxynitride (SiON) films possess the properties of amorphous silicon oxide (a-SiOx) and a-SiNx:H with variable n and less positive Q f compared with a-SiNx:H. In this study, we investigated the passivation and anti-reflection properties of Al2O3/SiON stacks. Initially, a SiON layer was deposited by plasma enhanced chemical vapor deposition with variable n and its chemical composition was analyzed by Fourier transform infrared spectroscopy. Then, the SiON layer was deposited as a capping layer on a 10 nm thick Al2O3 layer, and the electrical and optical properties were analyzed. The SiON capping layer with n = 1.47 and a thickness of 70 nm resulted in an interface trap density of 4.74 = 1010 cm-2 eV-1 and Q f of -2.59 = 1012 cm-2 with a substantial improvement in lifetime of 1.52 ms after industrial firing. The incorporation of an Al2O3/SiON stack on the front side of the n-type solar cells results in an energy conversion efficiency of 18.34% compared to the one with Al2O3/a-SiNx:H showing 17.55% efficiency. The short circuit current density and open circuit voltage increase by up to 0.83 mA cm-2 and 12 mV, respectively, compared to the Al2O3/a-SiNx:H stack on the front side of the n-type solar cells due to the good anti-reflection and front side surface passivation.

    Full Text Available Resumo A exemplo dos estabelecimentos de elite, Sion exerce sobre suas alunas um efeito de ordenação e de consagração, que tem por objetivo formar um grupo à parte, que faz corpo com a instituição. A "cultura escolar católica de tradição francesa" que anima as instituições femininas de ensino secundário no Brasil, em particular o Colégio Notre Dame de Sion, desenvolve em suas alunas um espírito de corpo específico, resultado de uma socialização conduzida num cotidiano altamente ritualizado. O presente artigo trata justamente de analisar as maneiras pelas quais se forma tal espírito de corpo. O esprit de Sion, espírito de corpo específico a Sion, vai assim ser formado através de rituais de identidade, rituais morais e rituais ligados à religião.Esse esprit de Sion vai conferir às alunas umhabitus, cujas estruturas estruturantes vão acompanhá-las até o fim da vida, contribuindo a assentar seu capital social, fazendo com que sejam reconhecidas em sociedade como enfants de Sion e se reconheçam entre si. Palavras-chave: cultura escolar católica de tradição francesa;espírito de corpo; enfants de Sion; esprit de Sion; rituais.   FORMATION OF SION`S SPIRIT Abstract Like elite’s establishments, Sion exerts on his/her female student’s ordinance and consecration effect with the objective to shape a distinctive group which becomes part of the institution body.“ Traditional French Catholic school culture” which liven up female high school in Brazil, particularly Colégio Notre Dame de Sion, develops in their female students a specific body spirit, resulting from socialization, conducted in highly ritualized daily routines. This article deals with analyzing the ways by which such body spirit is shaped, the esprit of Sion, spirit of body, specifically of Sion. Thus, it will be shaped through identity rituals, moral rituals and rituals related to religion. This Sion’s esprit will confer to classes a habitus whose

    This paper deals with the surface study of an industrial polydicyclopentadiene. First, the chemical structure of this polymer is presented. Then the contact angle measurements between the solid surface and various liquids are discussed. Surface energy value is 48 mJ/m2 for total energy and 3 mJ/m2 for the polar component. During ageing, surface polarity increases leading to a good paint adhesion and a great affinity for water. However, weak boundary layers formation is possible and discussed in the last part of this paper. Cet article concerne l'étude de la surface d'un polydicyclopentadiène industriel. Il débute par une brève présentation de la structure chimique de ce polymère. Les conditions de mesure de l'angle de contact de différents liquides et des tests d'adhésion sont précisées et mises au point. L'énergie de surface est de l'ordre de 48 mJ/m2 et comporte une faible composante polaire (3 mJ/m^2). Au cours du vieillissement, la polarité de surface augmente ce qui est à l'origine de la bonne adhésion des peintures et d'une grande affinité pour l'eau. Cependant dans certaines conditions il peut y avoir formation de couches de faible cohésion défavorable à l'accrochage.

    We have compiled photometric data from the Wide-field Infrared Survey Explorer All Sky Survey and other archival sources for the more than 2200 objects in the original McCook & Sion Catalog of Spectroscopically Identified White Dwarfs. We applied color-selection criteria to identify 28 targets whose infrared spectral energy distributions depart from the expectation for the white dwarf photosphere alone. Seven of these are previously known white dwarfs with circumstellar dust disks, five are known central stars of planetary nebulae, and six were excluded for being known binaries or having possible contamination of their infrared photometry. We fit white dwarf models to the spectral energy distributions of the remaining ten targets, and find seven new candidates with infrared excess suggesting the presence of a circumstellar dust disk. We compare the model dust disk properties for these new candidates with a comprehensive compilation of previously published parameters for known white dwarfs with dust disks....

    Rapid analysis of drugs in emergency room overdose patients is critical to selecting appropriate medical care. Saliva analysis has long been considered an attractive alternative to blood plasma analysis for this application. However, current clinical laboratory analysis methods involve extensive sample extraction followed by gas chromatography and mass spectrometry, and typically require as much as one hour to perform. In an effort to overcome this limitation we have been investigating metal-doped sol-gels to both separate drugs and their metabolites from saliva and generate surface-enhanced Raman spectra. We have incorporated the sol-gel in a disposable lab-on-a-chip format, and generally no more than a drop of sample is required. The detailed molecular vibrational information allows chemical identification, while the increase in Raman scattering by six orders of magnitude or more allows detection of microg/mL concentrations. Measurements of cocaine, its metabolite benzoylecgonine, and several barbiturates are presented.

We fit WD models to the spectral energy distributions of the remaining ten targets, and find seven new candidates with infrared excess suggesting the presence of a circumstellar dust disk. We compare the model dust disk properties for these new candidates with a comprehensive compilation of previously published parameters for known WDs with dust disks. It is possible that the current census of WDs with dust disks that produce an excess detectable at K-band and shorter wavelengths is close to complete for the entire sample of known WDs to the detection limits of existing near-IR all-sky surveys. The WD dust disk candidates now being found using longer wavelength infrared data are drawn from a previously underrepresented region of parameter space, in which the dust disks are overall cooler, narrower in radial extent, and/or contain fewer emitting grains.

    Angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a useful tool for non-destructive in-depth analysis of near surface regions. However, the reconstruction of depth profile from ARXPS data is an ill-posed mathematical problem. Thus, the main goal of this work was to develop a new, iterative algorithm based on the least square fitting which allows to solve this problem. The depth profiles were restored by dividing sample in thin virtual box shaped layers each with a different concentration. To extract information on the depth distribution, this algorithm is based on the analysis of the angular peak intensities along with the inelastic background. In addition, the physically trivial constraint of atomic fractions adding up to unity was imposed. The model takes into account the effect of elastic scattering and anisotropy of the photoelectric cross section. To test the algorithm, experimental spectrum for SiON samples on Si substrate were measured with a Thermo Theta Probe electron spectrometer for off-normal emission angles in the range between 25° and 75°. A very good agreement was found between the measured spectra and obtained spectra from the algorithm.

  12. Plasmonic effect of Ag nanoparticles in a SiON antireflective coating: engineering rules and physical barrier

    Surface plasmon polaritons have been proposed in the architectures of several solar cells as a way to enhance light collection and thus to increase their efficiency. Here, Ag nanoparticles (NPs) are embedded in a SiON antireflective layer using an electroless technique. The plasmonic effects are modeled and observed experimentally for NPs 5 to 200 nm in size. The systematic comparison of scattering and extinction efficiencies computed as a function of the NPs and surrounding medium properties allows establishing engineering rules, validated by the experimental measurements. The fact that Ag NPs larger than 30 nm mainly contribute to light scattering and therefore to optical path enlargement (green-red light), whereas those smaller than 15 nm absorb light by light trapping (blue-green), is demonstrated and physically explained. A physical barrier making it impossible to shift the dominant resonance beyond 650 nm is pointed out.

    2002-09-01

    The novel oxonitridosilicate oxide (sion oxide) Gd 3[SiON 3]O was obtained by the reaction of gadolinium metal with its carbonate oxide and silicon diimide in a radiofrequency (r.f.) furnace at a temperature of 1400°C. The crystal structure of Gd 3[SiON 3]O ( I4/ mcm, a=649.1(2) pm, c=1078.8(6) pm, Z=4, R1=0.0411, w R2=0.0769, 405 F2 values, 19 parameters, 123 K) is isotypic with that of Ba 3[SiO 4]O and Cs 3[CoCl 4]Cl. It can be derived from the perovskite structure type by a hierarchical substitution: Ti 4+→O 2-, O 2-→Gd 3+, Ca 2+→[SiON 3] 7- resulting in the formation of large [OGd 6] 16+ octahedra, which are twisted by ξ=16.47(1)° around [001]. The low-temperature single-crystal data investigation led to a crystallographic splitting of the central O atom which could not be resolved at room temperature. The UV-Vis absorption spectra in reflection geometry of the yellow title compound revealed two overlaying broad bands, one peaking at almost the same wavelength as observed in gadolinium oxide (340 nm) and a second red-shifted band at approximately 400 nm indicating a strong influence of nitrogen on the ligand field splitting of the 5 d states of Gd 3+. Temperature-dependent magnetic susceptibility measurements of Gd 3[SiON 3]O show Curie-Weiss behavior from 2 to 300 K with an experimental magnetic moment of 7.68(5) μB/Gd, indicating trivalent gadolinium. There is no evidence for magnetic ordering down to 2 K. According to the paramagnetic Curie temperature of -7(1) K, the exchange between the gadolinium magnetic moments is supposed to be only weak. The vibrational spectroscopic data (IR and Raman) are reported.

    We demonstrate efficient surface-emitting terahertz frequency quantum cascade lasers with continuous wave output powers of 20–25 mW at 15 K and maximum operating temperatures of 80–85 K. The devices employ a resonant-phonon depopulation active region design with injector, and surface emission is realized using resonators based on graded photonic heterostructures (GPHs). GPHs can be regarded as energy wells for photons and have recently been implemented through grading the period of the photonic structure. In this paper, we show that it is possible to keep the period constant and grade instead the lateral metal coverage across the GPH. This strategy ensures spectrally single-mode operation across the whole laser dynamic range and represents an additional degree of freedom in the design of confining potentials for photons.

    La pathomimie cutanée est une forme particulière de troubles factices relativement rare, et constitue l'un des problèmes les plus complexes pour le dermatologue. Nous rapportons un cas de pathomimie révélée par des lésions cutanées unilatérales, mimant une brûlure. Une jeune femme de 27 ans, était suivie depuis 4 ans pour une dépression. Elle a présenté 15j avant sa 1ère hospitalisation un placard inflammatoire du sein gauche compliqué de lésions bulleuses et d’érosions superficielles. La biopsie cutanée avait montré une dermite non spécifique. Une cicatrisation rapide sous traitement local a été notée. Elle a présenté 10 jours plus tard de nouvelles lésions similaires étagées au membre inférieur gauche, évoluant vers le décollement bulleux spontané. La biopsie cutanée avait montré un décollement bulleux jonctionnel et des foyers de nécrose ischémique. L'IFD était négative. Devant les données anamnestiques, cliniques, la négativité du bilan paraclinique, et la guérison des lésions sous pansements occlusifs seuls, le diagnostic de pathomimie a été évoqué et retenu. La patiente a été adressée en psychiatrie où une thérapie cognitivo-comportementale a été préconisée. Notre observation correspond à un tableau de pathomimie de présentation clinique particulière par sa localisation unilatérale et son caractère bulleux. Chez notre patiente qui est droitière, la localisation unilatérale gauche sur des zones accessibles, l'absence de lésions spécifiques à l'examen histologique, la cicatrisation rapide des lésions sous traitement local occlusif seul et leur récurrence malgré des soins adaptés étaient en faveur d'une pathologie factice. Néanmoins, la localisation au niveau des seins peut être très déroutante. Le caractère bulleux des lésions dans le cadre d'une pathomimie a été rarement rapporté. Dans notre cas, la pathomimie s'associe à des troubles anxieux et dépressifs très importants

    The growth of C60 films on the pseudo-ten-fold (1 0 0) surface of the orthorhombic Al13Co4 quasicrystalline approximant was studied experimentally by scanning tunneling microscopy, low-energy electron diffraction and photoemission spectroscopy. The (1 0 0) surface terminates at bulk-planes presenting local atomic configurations with five-fold symmetry—similar to quasicrystalline surfaces. While the films deposited at room temperature were found disordered, high-temperature growth (up to 693 K) led to quasi-ordered molecular films templated on the substrate rectangular unit mesh. The most probable adsorption sites and geometries were investigated by density functional theory (DFT) calculations. A large range of adsorption energies was determined, influenced by both symmetry and size matching at the molecule-substrate interface. The quasi-ordered structure of the film can be explained by C60 adsorption at the strongest adsorption sites which are too far apart compared to the distance minimizing the intermolecular interactions, resulting in some disorder in the film structure at a local scale. Valence band photoemission indicates a broadening of the molecular orbitals resulting from hybridization between the substrate and overlayer electronic states. Dosing the film at temperature above 693 K led to molecular damage and formation of carbide thin films possessing no azimuthal order with respect to the substrate.

    How soil fungi function in soil carbon and nutrient cycling is not well understood by using fungal enzymatic differences and their interactions with soil colloids. Eight extracellular enzymes, EEAs (chitinase, carboxymethyl cellulase, β-glucosidase, protease, acid phosphatase, polyphenol oxidase, laccase, and guaiacol oxidase) secreted by ten fungi were compared, and then the fungi that showed low and high enzymatic activity were co-cultured with soil colloids for the purpose of finding fungi-soil interactions. Some fungi (Gomphidius rutilus, Russula integra, Pholiota adiposa, and Geastrum mammosum) secreted 3–4 enzymes with weak activities, while others (Cyathus striatus, Suillus granulate, Phallus impudicus, Collybia dryophila, Agaricus sylvicola, and Lactarius deliciosus) could secret over 5 enzymes with high activities. The differences in these fungi contributed to the alterations of functional groups (stretching bands of O-H, N-H, C-H, C = O, COO- decreased by 11–60%, while P = O, C-O stretching, O-H bending and Si-O-Si stretching increased 9–22%), surface appearance (disappearance of adhesive organic materials), and elemental compositions (11–49% decreases in C1s) in soil colloids. Moreover, more evident changes were generally in high enzymatic fungi (C. striatus) compared with low enzymatic fungi (G. rutilus). Our findings indicate that inter-fungi differences in EEA types and activities might be responsible for physical and chemical changes in soil colloids (the most active component of soil matrix), highlighting the important roles of soil fungi in soil nutrient cycling and functional maintenance.

    At the fringe of Everglades National Park in southwest Florida, United States, the Ten Thousand Islands National Wildlife Refuge (TTINWR) habitat has been heavily affected by the disruption of natural freshwater flow across the Tamiami Trail (U.S. Highway 41). As the Comprehensive Everglades Restoration Plan (CERP) proposes to restore the natural sheet flow from the Picayune Strand Restoration Project area north of the highway, the impact of planned measures on the hydrology in the refuge needs to be taken into account. The objective of this study was to develop a simple, computationally efficient mass balance model to simulate the spatial and temporal patterns of water level and salinity within the area of interest. This model could be used to assess the effects of the proposed management decisions on the surface water hydrological characteristics of the refuge. Surface water variations are critical to the maintenance of wetland processes. The model domain is divided into 10 compartments on the basis of their shared topography, vegetation, and hydrologic characteristics. A diversion of +10% of the discharge recorded during the modeling period was simulated in the primary canal draining the Picayune Strand forest north of the Tamiami Trail (Faka Union Canal) and this discharge was distributed as overland flow through the refuge area. Water depths were affected only modestly. However, in the northern part of the refuge, the hydroperiod, i.e., the duration of seasonal flooding, was increased by 21 days (from 115 to 136 days) for the simulation during the 2008 wet season, with an average water level rise of 0.06 m. The average salinity over a two-year period in the model area just south of Tamiami Trail was reduced by approximately 8 practical salinity units (psu) (from 18 to 10 psu), whereas the peak dry season average was reduced from 35 to 29 psu (by 17%). These salinity reductions were even larger with greater flow diversions (+20%). Naturally, the reduction

    Full Text Available L’évaluation automatique de textes connaît actuellement un succès grandissant en raison de son importance dans le champ de l’éducation et, tout particulièrement, de l’apprentissage des langues étrangères. Si des systèmes efficaces ont été développés ces quinze dernières années, peu d’entre eux prennent en compte le niveau discursif. Récemment, quelques recherches ont proposé de remédier à cette lacune au moyen de mesures automatiques de la cohésion lexicale obtenues à partir d’une analyse sémantique latente, mais les résultats n’ont pas été conformes aux attentes. En s’inspirant d’un modèle bien connu de l’expertise rédactionnelle, la présente recherche propose d’employer un nouvel indice de cohésion dérivé des travaux en segmentation thématique de textes. L’efficacité de cet index est confirmée au travers de l’analyse d’un corpus de 223 textes d’apprenants de l’anglais comme langue étrangère. La conclusion discute les limitations principales de cette étude exploratoire et propose des pistes de développement.Automatic essay grading is currently experiencing a growing popularity because of its importance in the field of education and, particularly, in foreign language learning. While several efficient systems have been developed over the last fifteen years, almost none of them take the discourse level into account. Recently, a few studies proposed to fill this gap by means of automatic indexes of lexical cohesion obtained from Latent Semantic Analysis, but the results were disappointing. Based on a well-known model of writing expertise, the present study proposes a new index of cohesion derived from work on the thematic segmentation of texts. The efficiency of this index is supported through the analysis of a corpus of 223 essays of learners of English as a foreign language. The conclusion discusses the main limitations of this exploratory study and proposes further avenues

    Full Text Available The purpose of this study was to evaluate the surface tension of calcium hydroxide (CH associated with different substances (deionized distilled water, camphorated paramonochlorophenol, 2% chlorhexidine digluconate, Otosporin, 3% sodium lauryl ether sulphate; Furacin, PMC Furacin using tensiometer. The action of the substances studied on the dentinal structure enhances the property of surface tension. This method consists in the application of force to separate a platinum ring immersed in the substances. Thus, torsion was applied to the screw until the platinum ring separated during substances testing. Considering the methodology applied, the following can be concluded: distilled water alone or associated with CH presented a high surface tension (70.00 and 68.40 dynes/cm; calcium hydroxide in association with anionic detergent showed low surface tension (31.60 dynes/cm; camphorated paramonochlorophenol plus CH presented low surface tension (37.50 dynes/cm; 2% chlorhexidine associated with calcium hydroxide showed high surface tension values (58.00 dynes/cm; Otosporin plus calcium hydroxide showed low surface tension (35.40 dynes/cm; paramonochlorophenol Furacin mixed with calcium hydroxide presented surface tension equal to 45.50 dynes/cm; sodium hypochlorite presented high surface tension (75.00 dynes/cm. Antimicrobial agents more indicated in endodontics, i.e. CH, chlorhexidine and hypochlorite, presented the highest surface tension.Estudou-se a tensão superficial do hidróxido de cálcio associado a diferentes substâncias (água destilada deionizada, paramonoclorofenol canforado, digluconato de clorexidina 2%, Otosporin, sulfato éter lauril sódio 3%, furacin, PMC furacin usando tensiômetro.

    Toxic epidermal necrolysis (TEN) is a severe exfoliative disease of the skin and mucous membranes that results in high mortality. As the elderly population increases, the number of elderly patients with TEN can also be expected to increase. Elderly patients with comparably sized burn wounds usually have a poor prognosis. Our purpose was to determine whether elderly TEN patients exhibit similarly high mortality. A retrospective review was conducted of 52 patients treated for TEN from October 1991 through September 1998. Eleven patients were older than 65 years. All patients were treated according to our TEN protocol. Eight of 11 patients recovered, and 3 died. The mean total body surface area (TBSA) involvement for the patients who recovered was 24%, compared with 66% for the nonsurvivors. The survival rate for elderly patients (73%) compares well with that for those younger than 65 years (89%). Therefore, we propose that we should be aggressive in treating elderly patients with TEN.

    Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago's waterfront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative powers of ten—10-1 m (10 centimeters), and so forth, until we are viewing a carbon nucl...

    Full Text Available In this article, we designed and studied silicon oxynitride (SiON microring-based photonic structures for biosensing applications. We designed waveguides, directional couplers, and racetrack resonators in order to measure refractive index changes smaller than 10−6 refractive index units (RIU. We tested various samples with different SiON refractive indexes as well as the waveguide dimensions for selecting the sensor with the best performance. Propagation losses and bending losses have been measured on test structures, along with a complete characterization of the resonator’s performances. Sensitivities and limit of detection (LOD were also measured using glucose-water solutions and compared with expected results from simulations. Finally, we functionalized the resonator and performed sensing experiments with Aflatoxin M1 (AFM1. We were able to detect the binding of aflatoxin for concentrations as low as 12.5 nm. The results open up the path for designing cost-effective biosensors for a fast and reliable sensitive analysis of AFM1 in milk.

    Prior to the recently successfully launched OCO-2 mission, global near-surface-sensitive satellite observations of carbon dioxide (CO2) have been made with SCIAMACHY/ENVISAT during 2002-2012 and are still being made since 2009 with TANSO-FTS/GOSAT, which also deliver atmospheric methane (CH4). The SCIAMACHY and GOSAT overlapping time series of atmospheric column-averaged mole fractions, i.e., XCO2 and XCH4, now cover more than 10 years. During the last years significant progress has been made in improving the quality of the XCO2 and XCH4 data products retrieved from SCIAMACHY and GOSAT and in extending the time series so that more and more applications can be addressed. In this presentation we present some recent results related to CO2 and CH4 sources and sinks. The SCIAMACHY products have been generated using retrieval algorithms developed at University of Bremen. For XCO2 we use an ensemble of data products generated using GOSAT retrieval algorithms developed in Japan (at NIES), in the US (at NASA/JPL and collaborating institutes) and at European institutions (University of Leicester, UK, and SRON, Netherlands, in collaboration with KIT, Germany). Focus will be on three applications: (i) An assessment of the strength of the European terrestrial carbon sink during 2003-2010 based on an ensemble of SCIAMACHY (2003-2010) and GOSAT (2010) XCO2 data products, (ii) an assessment of CO2 and NO2 anthropogenic emission and emission ratio trends using co-located SCIAMACHY XCO2 and NO2 observations over Europe, North America and East Asia, and (iii) an analysis of SCIAMACHY XCH4 retrievals during 2006-2011 over North America focusing on fugitive methane emissions from oil and gas production using tight geological formations ("fracking"). It will be shown that (i) the European terrestrial carbon sink appears to be stronger than expected, (ii) that recent Chinese CO2 and NO2 emissions are increasing but with a trend towards reduced NO2-to-CO2 emission ratios pointing to

    Pamela experiment has been designed as a cosmic ray observatory at 1 AU, dedicated to the precise and high statistics study of CR fluxes on a three decades energy range, form a few tens MeV up to several hundred GeV region. It is the last step of the 'Russian-Italian Mission' (RIM) program born in 1992 between several Italian and Russian institutes and with the participation of the Royal Institute of Technology of Stockholm (Sweden) and the Siegen University (German). Launched the 16 June 2006 from Baikonur cosmodrome on board of the Resurs-DK1 Russian satellite by a Soyuz rocket in an elliptical (350-610 km) quasi polar orbit (70° inclination) it was activated on 21 June 2006, afterword has been in a continuous data taking mode for ten years. The Pamela program pays particular attention to the study of particles (protons and electrons) and antiparticles (antiprotons and positrons) energy spectra. It also includes search for possible signals of dark matter annihilation, search for primordial antimatter (antihelium), search for new Matter in the Universe (Strangelets?), study of cosmic-ray propagation, solar physics and solar modulation, terrestrial magnetosphere. This program is made possible thanks to the outstanding performance of the instrument, the low energy threshold, the quasi-polar orbit, the 10 years duration of the observation. Protons and helium nuclei are the most abundant components of the cosmic radiation and the precise measurements of their fluxes allow understanding the acceleration and propagation of cosmic rays in the Galaxy. Their spectral shapes cannot be well described by a single power law: at 230-240 GV they exhibit an abrupt spectral hardening. They challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy. Of paramount importance is the discover of the anomalous increase of the positron flux at energies higher that 50 GeV (the so called 'Pamela anomaly'). The review of

    In the Korean culture the family members are recorded in special family books. This makes it possible to follow the distribution of Korean family names far back in history. It is here shown that these name distributions are well described by a simple null model, the random group formation (RGF) model. This model makes it possible to predict how the name distributions change and these predictions are shown to be borne out. In particular, the RGF model predicts that, for married women entering a collection of family books in a certain year, the occurrence of the most common family name "Kim" should be directly proportional the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to high degree. We speculate that it reflects some inherent social stability in the Korean culture. In addition, we obtain an estimate of the total population of the Korean culture down to year 500 AD, based on the RGF model and find about ten thousand Kims.

    Hydrodynamic effects play a very important role in the contaminants release from sediments. Experiments were perfor-med to study contaminants releasing characteristics due to resuspension. The time-dependent variation of COD concentration and re-lative roles under static and dynamic state of the overlying water were analyzed. Experimental results showed that COD concen-tration in the water column got a striking increment on the dynamic conditions, mainly by reducing the thickness of concentration boundary layer near sediment-water interface and destructing the surface structure of sediment. Hydrodynamics increased contamina-nts release rates and flux in unit time. Before reaching an equilibrium stage, the dynamic release caused by the resuspension was more effective than static one due to molecular diffusion. The release rate of COD increased with flow velocity and decreased with water depth. But at a shallow water depth, wave effects would dominate the causing resuspension, resulting in contaminants release in large quantity. The intensity of pollutant release increased with time in a rather circuitous process. The diffusion of pollutant from internal sediment to the sediment-water interface would maintain the endogenous release effects.

    The effect of the anisotropic interracial en-ergy on dendritic growth has been an important sub-ject, and has preoccupied many researchers in the field of materials science and condensed matter physics. The present paper is dedicated to the study of the effect of full 3-D anisotropic Surface tension on the steady state solution of dendritic growth. We obtain the analytical form of the first order approximation solution in the reg-ular asymptotic expansion around the Ivantsov's nee-dle growth solution, which extends the steady needle growth solution of the system with isotropic surface ten-sion obtained by Xu and Yu (J. J. Xu and D. S. Yu, J. Cryst. Growth, 1998, 187: 314; J. J. Xu, Interfa-cial Wave Theory of Pattern Formation: Selection of Dendrite Growth and Viscous Fingering in a Hele-Shaw Flow, Berlin: Springer-Verlag, 1997).The solution is expanded in the general Laguerre se-ries in any finite region around the needle-tip, and it is also expanded in a power series in the far field behind the tip. Both solutions are then numerically matched in the intermediate region. Based on this global valid solution, the dependence of Peclet number Pe and the interface's morphology on the anisotropy parameter of surface ten-sion as well as other physical parameters involved are determined. On the basis of this global valid solution, we explore the effect of the anisotropy parameter on the Peclet number of growth, as well as the morphology of the interface.

    Full Text Available Sion Sono’s Guilty of Romance (Koi no tsumi, 2011 was adapted from an actual crime in Tokyo’s love hotel: an educated woman (a prostitute at night was found decapitated and her limbs were re-assembled with a sex-doll. Sono renders this through his cinematic narrative blurring the distinction between true crime and fictional sin like Rancière’s idea that everything is a narrative dissipating the opposition between “fact and fiction,” and “quasi-body” becomes a product of human literarity while an imaginary collective body is formed to fill the fracture in-between. In Sono’s story, the victim is a literature professor tormented by an incestuous desire for her father, whose favorite book is Kafka’s Castle. Thus she compares the love-hotel district where she turns loose at night as a castle of lusts. Here the narrative becomes a collective body that puppeteers human “quasi-bodies” in a Kafkaesque spatio-temporal aporia, and time’s spatialized horizontally with the germs of desire spread like a contagion on a Deleuzian “plane of immanence.”

    Good optical-quality SiON layers deposited upon a SiO(2) buffer layer placed upon silicon wafers have been obtained by using plasma-enhanced chemical vapor deposition from SiH(4), NH(3), and N(2)O. Optical planar waveguides with a thickness of 5 microm and a refractive index of 1.470 have been deposited and investigated in the wavelength region of 1.3-1.6 microm. Three absorption bands at 1.40, 1.48, and 1.54 microm have been detected and interpreted as Si-OH, N-H, and Si-H vibrational modes, respectively. Absorption losses of 3.8 dB/cm at 1.4 microm and 3.2 dB/cm at 1.51 microm have been measured. A mild annealing at approximately 800 degrees C completely removes the band at 1.40 microm, whereas strong reduction of absorption at 1.51 microm requires 3 h of annealing at 1100 degrees C. As a result, propagation losses of 0.36 to 0.54 dB/cm have been measured at 1.54-microm wavelength.

  4. Development, Testing, and Application of a Coupled Hydrodynamic Surface-Water/Groundwater Model (FTLOADDS) with Heat and Salinity Transport in the Ten Thousand Islands/Picayune Strand Restoration Project Area, Florida

    2009-01-01

    A numerical model application was developed for the coastal area inland of the Ten Thousand Islands (TTI) in southwestern Florida using the Flow and Transport in a Linked Overland/Aquifer Density-Dependent System (FTLOADDS) model. This model couples a two-dimensional dynamic surface-water model with a three-dimensional groundwater model, and has been applied to several locations in southern Florida. The model application solves equations for salt transport in groundwater and surface water, and also simulates surface-water temperature using a newly enhanced heat transport algorithm. One of the purposes of the TTI application is to simulate hydrologic factors that relate to habitat suitability for the West Indian Manatee. Both salinity and temperature have been shown to be important factors for manatee survival. The inland area of the TTI domain is the location of the Picayune Strand Restoration Project, which is designed to restore predevelopment hydrology through the filling and plugging of canals, construction of spreader channels, and the construction of levees and pump stations. The effects of these changes are simulated to determine their effects on manatee habitat. The TTI application utilizes a large amount of input data for both surface-water and groundwater flow simulations. These data include topography, frictional resistance, atmospheric data including rainfall and air temperature, aquifer properties, and boundary conditions for tidal levels, inflows, groundwater heads, and salinities. Calibration was achieved by adjusting the parameters having the largest uncertainty: surface-water inflows, the surface-water transport dispersion coefficient, and evapotranspiration. A sensitivity analysis did not indicate that further parameter changes would yield an overall improvement in simulation results. The agreement between field data from GPS-tracked manatees and TTI application results demonstrates that the model can predict the salinity and temperature

  11. Ten Problems in Experimental Mathematics

    Energy Technology Data Exchange (ETDEWEB)

    Bailey, David H.; Borwein, Jonathan M.; Kapoor, Vishaal; Weisstein, Eric

    2004-09-30

    This article was stimulated by the recent SIAM ''100 DigitChallenge'' of Nick Trefethen, beautifully described in a recent book. Indeed, these ten numeric challenge problems are also listed in a recent book by two of present authors, where they are followed by the ten symbolic/numeric challenge problems that are discussed in this article. Our intent was to present ten problems that are characteristic of the sorts of problems that commonly arise in ''experimental mathematics''. The challenge in each case is to obtain a high precision numeric evaluation of the quantity, and then, if possible, to obtain a symbolic answer, ideally one with proof. Our goal in this article is to provide solutions to these ten problems, and in the process present a concise account of how one combines symbolic and numeric computation, which may be termed ''hybrid computation'', in the process of mathematical discovery.

    We report the fabrication of an ultra-thin silicon oxynitride (SiON) as an interfacial layer (IL) for n-Si/ALD-HfO2 gate stack with reduced leakage current. The XRD, AFM, FTIR, FESEM and EDAX characterizations have been performed for structural and morphological studies. Electrical parameters such as dielectric constant (K), interface trap density (Dit), leakage current density (J), effective oxide charge (Qeff), barrier height (Φbo), ideality factor (ƞ), breakdown-voltage (Vbr) and series resistance (Rs) were extracted through C-V, G-V and I-V measurements. The determined values of K, Dit, J, Qeff, Φbo, ƞ, Vbr and Rs are 14.4, 0.5 × 10 11 eV-1 cm-2, 2.2 × 10-9 A/cm2, 0.3 × 1013 cm-2, 0.42, 2.1, -0.33 and 14.5 MΩ respectively. SiON growth prior to HfO2 deposition has curtailed the problem of high leakage current density and interfacial traps due to sufficient amount of N2 incorporated at the interface.

    2002-01-01

    It seems to me at this time that two recent developments may permit fast progress on our way to understand the symmetry structure of toroidally (compactified and) reduced M-theory. The first indication of a (possibly) thin spot in the wall that prevents us from deriving a priori the U-duality symmetries of these models is to be found in the analysis of the hyperbolic billiards that control the chaotic time evolution of (quasi)homogeneous anisotropic String, Supergravity or Einstein cosmologies near a spacelike singularity. What happens is that U-duality symmetry controls chaos via negative constant curvature. On the other hand it was noticed in 1982 that (symmetrizable) ''hyperbolic'' Kac-Moody algebras have maximal rank ten, exactly like superstring models and that two of these four rank ten algebras matched physical theories. My second reason for optimism actually predates also the previous breakthrough, it was the discovery in 1998 of surprising superalgebras extending U-dualities to all (p+1)-forms (assoc...

Credible types of potential future accidental intrusion into the WIPP are estimated as a basis for creating warning markers to prevent inadvertent intrusion. A six-step process is used to structure possible scenarios for such intrusion, and it is concluded that the probability of inadvertent intrusion into the WIPP repository over the next ten thousand years lies between one and twenty-five percent. 3 figs., 5 tabs.

    L'oxydation sous air de deux nickel de pureté industrielle mais de provenance différente a été étudiée, principalement à 800^{circ}C. Outre la cinétique d'oxydation et la morphologie des couches de NiO, l'étude a été focalisée sur les caractéristiques mécaniques des couches de NiO. Celles-ci ont été caractérisées à la température ambiante, essentiellement par flexion trois points sous MEB. Si la cinétique d'oxydation des deux métaux industriels est voisine et associée à des morphologies de couches assez complexes mais similaires, il n'en est pas de même pour la majorité des caractéristiques mécaniques. Ainsi, même en prenant en compte l'évolution des caractéristiques mécaniques du nickel avec le temps de traitement, on observe des différences dans les valeurs de KIC des couches de NiO selon la nature du substrat et l'épaisseur de la couche d'oxyde, c'est-à-dire avec la durée de l'oxydation. Enfin et surtout, le comportement vis-à-vis de la décohésion est très différent : il est pratiquement impossible d'écailler les couches de NiO formées sur l'un des nickel, tandis que la décohésion est obtenue avec une relative facilité dans le cas de l'autre nickel. Mais, cette décohésion n'a pas lieu à l'interface métal-oxyde, mais à l'interface oxyde-oxyde, en raison de la formation de deux couches de NiO, l'une interne, l'autre externe.

    2017-10-09

    Fibromyalgia is characterised by persistent, widespread pain; sleep problems; and fatigue. Transcutaneous electrical nerve stimulation (TENS) is the delivery of pulsed electrical currents across the intact surface of the skin to stimulate peripheral nerves and is used extensively to manage painful conditions. TENS is inexpensive, safe, and can be self-administered. TENS reduces pain during movement in some people so it may be a useful adjunct to assist participation in exercise and activities of daily living. To date, there has been only one systematic review in 2012 which included TENS, amongst other treatments, for fibromyalgia, and the authors concluded that TENS was not effective. To assess the analgesic efficacy and adverse events of TENS alone or added to usual care (including exercise) compared with placebo (sham) TENS; no treatment; exercise alone; or other treatment including medication, electroacupuncture, warmth therapy, or hydrotherapy for fibromyalgia in adults. We searched the following electronic databases up to 18 January 2017: CENTRAL (CRSO); MEDLINE (Ovid); Embase (Ovid); CINAHL (EBSCO); PsycINFO (Ovid); LILACS; PEDRO; Web of Science (ISI); AMED (Ovid); and SPORTDiscus (EBSCO). We also searched three trial registries. There were no language restrictions. We included randomised controlled trials (RCTs) or quasi-randomised trials of TENS treatment for pain associated with fibromyalgia in adults. We included cross-over and parallel-group trial designs. We included studies that evaluated TENS administered using non-invasive techniques at intensities that produced perceptible TENS sensations during stimulation at either the site of pain or over nerve bundles proximal (or near) to the site of pain. We included TENS administered as a sole treatment or TENS in combination with other treatments, and TENS given as a single treatment or as a course of treatments. Two review authors independently determined study eligibility by assessing each record and

    We present first results for lattice simulations, on a single volume, of the low-lying spectrum of an SU(3) Yang-Mills gauge theory with ten light fermions in the fundamental representation. Fits to the fermion mass dependence of various observables are found to be globally consistent with the hypothesis that this theory is within or just outside the strongly-coupled edge of the conformal window, with mass anomalous dimension approximately equal to 1 over the range of scales simulated. We stress that we cannot rule out the possibility of spontaneous chiral-symmetry breaking at scales well below our infrared cutoff. We discuss important systematic effects, including finite-volume corrections, and consider directions for future improvement.

A batch of 10 superconducting decapole magnets for the LHC has just arrived at CERN from India. These will be used to correct for slight imperfections in the dipole magnets that will steer proton beams around CERN's new accelerator. All magnets have slight imperfections in the fields they produce, and in the LHC dipoles these will be corrected for using sextupoles and decapoles. The sextupoles were the first LHC magnets to be given the production green-light following successful tests of pre-series magnets last year (Bulletin 21/2000, 22 May 2000). Now it is the turn of pre-series decapoles to go on trial at CERN. Of the LHC's 1232 dipole magnets, half will use sextupole correctors only and the other half will use both sextupoles and decapoles. That means that a total of 616 pairs of decapoles are needed. Like the sextupole...

  3. Mode size converter between high-index-contrast waveguide and cleaved single mode fiber using SiON as intermediate material.

    High-index-contrast (HIC) waveguide such as Si and Si3N4 has small mode size enabling compact integration. However, the coupling loss with single mode fiber is also remarkable owning to the mode mismatching. Therefore, mode size converter, as the interface between HIC waveguide and optical fiber, takes an important role in the field of integrated optics. The material with refractive index (RI) between HIC waveguide and optical fiber can be used as a bridge to reduce the mode mismatching loss. In this letter, we employ silicon oxynitride (SiON) with RI about 1.50 as the intermediate material and optimize the structure of the SiON waveguide to match with cleaved single mode fiber and HIC waveguide separately. Combined with inverse taper and suspended structure, the mismatching loss is reduced and the dependence to the dimension of the structure is also released. The coupling loss is 1.2 and 1.4 dB/facet for TE and TM mode, respectively, with 3 dB alignment tolerance of ± 3.5 μm for Si(3)N(4) waveguide with just 200 nm-wide tip. While for Si waveguide, a critical dimension of 150 nm is applied due to the higher index contrast than Si(3)N(4) waveguide. Similar alignment tolerance is realized with coupling loss about 1.8 and 2.1 dB/facet for TE and TM mode. The polarization dependence loss (PDL) for both platforms is within 0.5 dB.

    Full Text Available The channel fluorine implantation (CFI process was integrated with the Si3N4 contact etch stop layer (SiN CESL uniaxial-strained n-channel metal-oxide-semiconductor field-effect transistor (nMOSFET with the hafnium oxide/silicon oxynitride (HfO2/SiON gate stack. The SiN CESL process clearly improves basic electrical performance, due to induced uniaxial tensile strain within the channel. However, further integrating of the CFI process with the SiN CESL-strained nMOSFET exhibits nearly identical transconductance, subthreshold swing, drain current, gate leakage and breakdown voltage, which indicates that the strain effect is not affected by the fluorine incorporation. Moreover, hydrogen will diffuse toward the interface during the SiN deposition, then passivate dangling bonds to form weak Si-H bonds, which is detrimental for channel hot electron stress (CHES. Before hydrogen diffusion, fluorine can be used to terminate oxygen vacancies and dangling bonds, which can create stronger Hf-F and Si-F bonds to resist consequent stress. Accordingly, the reliability of constant voltage stress (CVS and CHES for the SiN CESL uniaxial-strained nMOSFET can be further improved by the fluorinated HfO2/SiON using the CFI process. Nevertheless, the nMOSFET with either the SiN CESL or CFI process exhibits less charge detrapping, which means that a greater part of stress-induced charges would remain in the gate stack after nitrogen (SiN CESL or fluorine (CFI incorporation.

  5. Two shallow donors related to Zn interstitial in S-ion implanted ZnO epitaxial film

    Kamioka, K.; Kuriyama, K.; Kushida, K.

    2014-06-01

    Two shallow donors are observed in sulfur-ion implanted ZnO epitaxial films on sapphire substrates. The resistivity varies from ~103 Ω cm for un-implanted samples to 1.7×10-2 Ω cm for as-implanted ones. This low resistivity is attributed to zinc interstitial (Zni), corresponding to the activation energy (26 meV) estimated from the temperature dependence of electron concentration. The presence of Zni is evaluated from ion channeling by Rutherford backscattering spectroscopy. The disordered concentration is ~40% of Zn atoms at a maximum point (300 nm) from the surface in as-implanted samples and recovers to ~80% after 1000 °C annealing. In 1000 °C annealed samples, a shallower donor level of 12 meV is observed, suggesting the presence of complex defects consisting of remaining Zni and sulfur atoms replaced to the oxygen atom.

    2016-09-01

    Recently acquired geochronological and stratigraphic data provide new information on the sedimentary successions deposited by the Paleo-Tiber River in the coastal and near-coastal area of Rome in consequence of the glacio-eustatic changes, allowing to better define their inner geometry and palaeogeographic spatial distribution. In the present work we use this revised sedimentary dataset to provide a geochronologically constrained and tectonically adjusted record of paleo sea-level indicators. Aimed at this scope, we review literature data acquired in the last 35 years and using the new geochronological constraints we pinpoint the coastal-to-fluvial terraces of MIS 5 and MIS 7, mapping their relic surfaces in an area of 30 km along the coast north and south of the Tiber River mouth, and 20 km inland of the fluvial valleys of Tiber and Aniene rivers. The geometry of these paleo-surfaces provides constraints on the relative elevation of the sea-level during the last interglacials and on the uplift rates in this region during the last 200 ka. In particular, we recognize the previously undetected terraces of MIS 5.3 and MIS 5.1 interstadials, and we assess their spatial relationship with respect to MIS 5.5, providing important information on sea-level oscillations during this time span. Comparison with sea-level indicators provided by previous aggradational successions deposited during past interglacials spanning MIS 9 through MIS 21 in the coastal area of Rome, also allows us to reconstruct the tectonic history and investigate its relationships with the Middle-Pleistocene volcanic activity of the Roman Comagmatic Region along the Tyrrhenian Sea margin of Italy in the last 900 ka.

Foram desenvolvidos métodos para avaliação da tensão superficial e da área de molhamento. Para analisar a tensão fez-se pesagens das gotas formadas na extremidade de uma bureta, com os seguintes tratamentos combinados de forma fatorial (3 x 5 x 11: 3 surfatantes (Extravon, Aterbane e Silwet L-77, 5 concentrações do herbicida, produto comercial Roundup (0; 1; 2; 3,5 e 5 % e 11 concentrações de cada surfatantes (0; 0,005; 0,01; 0,02; 0,05; 0,1; 0,2; 0,5; 1; 2 e 3,5 %, num total de 165 tratamentos. Para avaliar a área de molhamento nas folhas de tiririca aplicou-se gotas de 0,48 .l. Os dados foram ajustados pelo modelo de Mitscherlich e, observou-se que para o surfatante Extravon que a eficiência decrescia gradativamente a medida em que aumentava a concentração do herbicida; para o Aterbane a eficiência foi reduzida apenas em baixas concentrações; já o surfatante Silwet L-77 apresentou eficiência bem superior aos demais e sua eficiência foi pouco alterada com a adição herbicida. Houve uma correlação positiva entre área de molhamento e tensão superficial. Concluiu-se, ainda, que não basta um surfatante reduzir a tensão superficial da água destilada, para que possa ser recomendado seu uso agrícola, assim, o surfatante deve ser submetido a testes preliminares com os defensivos em que serão conjugados para posterior recomendação.This research was undertaken to develop methods to evaluate the surface tension and foliar wetting of surfactant added in herbicide.

    Compared with the well documented neurophysiological findings on negative emotions, much less is known about positive emotions. In the present study, we explored the EEG correlates of ten different positive emotions (joy, gratitude, serenity, interest, hope, pride, amusement, inspiration, awe, and love). A group of 20 participants were invited to watch 30 short film clips with their EEGs simultaneously recorded. Distinct topographical patterns for different positive emotions were found for the correlation coefficients between the subjective ratings on the ten positive emotions per film clip and the corresponding EEG spectral powers in different frequency bands. Based on the similarities of the participants’ ratings on the ten positive emotions, these emotions were further clustered into three representative clusters, as ‘encouragement’ for awe, gratitude, hope, inspiration, pride, ‘playfulness’ for amusement, joy, interest, and ‘harmony’ for love, serenity. Using the EEG spectral powers as features, both the binary classification on the higher and lower ratings on these positive emotions and the binary classification between the three positive emotion clusters, achieved accuracies of approximately 80% and above. To our knowledge, our study provides the first piece of evidence on the EEG correlates of different positive emotions. PMID:28184194

    Science.gov (United States)

    Francis, Richard

    2012-05-01

    Because TENS is applied inconsistently and not always in line with optimal TENS application theory, this may explain why TENS for labour pain appears to be effective in some individuals and not in others. This article reviews TENS theory, advises upon optimal TENS application for labour pain and discusses some of the limitations of TENS research on labour pain. TENS application for labour pain may include TENS applied to either side of the lower spine, set to 200 mus pulse duration and 100 pulses per second. As pain increases, TENS intensity should be increased and as pain decreases, TENS intensity should be reduced to maintain a strong but pain free intensity of stimulation. This application may particularly reduce back pain during labour.

    Interdisciplinary team work is increasingly prevalent, supported by policies and practices that bring care closer to the patient and challenge traditional professional boundaries. To date, there has been a great deal of emphasis on the processes of team work, and in some cases, outcomes. This study draws on two sources of knowledge to identify the attributes of a good interdisciplinary team; a published systematic review of the literature on interdisciplinary team work, and the perceptions of over 253 staff from 11 community rehabilitation and intermediate care teams in the UK. These data sources were merged using qualitative content analysis to arrive at a framework that identifies characteristics and proposes ten competencies that support effective interdisciplinary team work. Ten characteristics underpinning effective interdisciplinary team work were identified: positive leadership and management attributes; communication strategies and structures; personal rewards, training and development; appropriate resources and procedures; appropriate skill mix; supportive team climate; individual characteristics that support interdisciplinary team work; clarity of vision; quality and outcomes of care; and respecting and understanding roles. We propose competency statements that an effective interdisciplinary team functioning at a high level should demonstrate.

    Periprosthetic joint infection (PJI) is one of the most serious complications following total knee arthroplasty (TKA). The demand for TKA is rapidly increasing, resulting in a subsequent increase in infections involving knee prosthesis. Despite the existence of common management practices, the best approach for several aspects in the management of periprosthetic knee infection remains controversial. This review examines the current understanding in the management of the following aspects of PJI: preoperative risk stratification, preoperative antibiotics, preoperative skin preparation, outpatient diagnosis, assessing for infection in revision cases, improving culture utility, irrigation and debridement, one and two-stage revision, and patient prognostic information. Moreover, ten strategies for the management of periprosthetic knee infection based on available literature, and experience of the authors were reviewed. PMID:24368992

    An improved micellar electrokinetic capillary chromatography method (MEKC) for the simultaneous determination of ten preservatives in ten different kinds of food samples was reported. An uncoated fused-silica capillary with 50 μm i.d. and 70 cm total length was used. Under the optimized conditions, the linear response was observed in the range of 1.2-200mg/L for the analytes. The limits of detection (LOD, S/N=3) and limits of quantitation (LOQ, S/N=10) ranging from 0.4 to 0.5mg/L and 1.2 to 1.5mg/L, respectively were obtained. The method was used for the determination of sorbic and benzoic acids in two FAPAS® (Food Analysis Performance Assessment Scheme) proficiency test samples (jam and chocolate cake). The results showed that the current method with simple sample pretreatment and small reagent consumption could meet the needs for routine analysis of the ten preservatives in ten types of food products.

    2014-05-01

    In this presentation we will provide a detailed review of the science highlights of the ENA observations obtained by The Ion Neutral Camera (INCA) on board Cassini. Since the launch of Cassini, INCA has unveiled an invisible world of hot plasma and neutral gas of the two biggest objects of our solar system: the giant magnetosphere of Jupiter and Saturn. Although more than ten years ago, INCA captured the first ENA images of the Jovian system revealing magnetospheric dynamics and an asymmetric Europa neutral gas torus. Approaching Saturn, INCA observed variability of Saturn's magnetospheric activity in response to changes in solar wind dynamic pressure, which was contrary to expectations and current theories. In orbit around Saturn, INCA continued the surprises including the first imaging and global characterization of Titan's exosphere extended out to its gravitational Hill sphere; recurring injections correlating with periodic Saturn Kilometric Radiation (SKR) bursts and magnetic field perturbations; and the discovery of energetic ionospheric outflow. Perhaps most significant, and the focal point of this presentation, is INCA's contribution to the understanding of global magnetospheric particle acceleration and transport, where the combination between ENA imaging and in-situ measurements have demonstrated that transport and acceleration of plasma is likely to occur in a two-step process. First, large-scale injections in the post-midnight sector accelerate and transport plasma in to about 12 RS up to energies of several hundreds of keV. Second, centrifugal interchange acts on the plasma inside of this region and provides further heating and transport in to about 6RS. We discuss this finding in the context of the two fundamental types of injections (or ENA intensifications) that INCA has revealed during its ten years of imaging. The first type is large-scale injections appearing beyond 12 RS in the post-midnight sector that have in many cases had an inward component

The size of complete chloroplast genomes and LSC and SSC regions of three species of Solanum is comparatively smaller than that of any other species studied till date (exception: SSC region of A. belladonna. AT content of coding regions was found to be less than noncoding regions. A duplicate copy of trnH gene in C. annuum and two alternative tRNA genes for proline in D. stramonium were observed for the first time in this analysis. Further, homology search revealed the presence of rps19 pseudogene and infA genes in A. belladonna and D. stramonium, a region identical to rps19 pseudogene in C. annum and orthologues of sprA gene in another six species. Among the eighteen intron-containing genes, 3 genes have two introns and 15 genes have one intron. The longest insertion was found in accD gene in C. annuum. Phylogenetic analysis using concatenated protein coding sequences gave two clades, one for Nicotiana species and another for Solanum, Capsicum, Atropa, and Datura.

    2013-01-01

    The study of multimodal communication has become an active and vibrant field. This special issue of Behavioral Ecology and Sociobiology brings together new developments in this rapidly expanding area. In this final contribution to the special issue, I look to the future and discuss ten questions in need of further work, touching on issues ranging from theoretical modeling and the evolution of behavior to molecular mechanisms and the development of behavior. In particular, I emphasize that the use of multimodal communication allows animals to switch between sensory channels when one channel becomes too noisy, and suggest that a better understanding of this process may help us both to understand the evolution of multisensory signaling and to predict the success of species facing environmental changes that affect signaling channels, such as urbanization and climate change. An expanded section is included on the effects of climate change on animal communication across sensory channels, urging researchers to pursue this topic due to the rapidity with which the environment is currently transforming.

    2003-01-01

    Ten years ago, CERN issued a statement declaring that a little known piece of software called the World Wide Web was in the public domain. Nowadays, the Web is an indispensable part of modern communications. The idea for the Web goes back to March 1989 when CERN Computer scientist Tim Berners-Lee wrote a proposal for a 'Distributed Information Management System' for the high-energy physics community. The Web was originaly conceived and developed to meet the demand for information sharing between scientists working all over the world. There were many obstacles in the 1980s to the effective exchange of information. There was, for example a great variety of computer and network systems, with hardly any common features. The main purpose of the web was to allow scientists to access information from any source in a consistent and simple way. By Christmas 1990, Berners-Lee's idea had become the World Wide Web, with its first server and browser running at CERN. Through 1991, the Web spread to other particle physics ...

    Button osteoma presents as small circumscribed ivory-like lumps on the skull vault. Although not rare, its diagnosis can be challenging for dermatologists. To clarify the clinical characteristics of button osteoma by reviewing 10 cases. Ten patients diagnosed with button osteoma at the Department of Dermatology, Kyungpook National University Hospital, between January 2011 and August 2014 were enrolled. We retrospectively reviewed medical records and analyzed demographic and clinical characteristics including sex, age, sites, number of lesions, symptoms, duration, histopathological finding, radiological findings, and treatment. All patients presented with an asymptomatic small circumscribed hard lump fixed to a bony structure. There were 9 female and 1 male patient, and the mean age was 54 years (range, 28~61 years). The most common site was the forehead, and disease duration ranged from 2 weeks to more than 20 years. The differential diagnosis included cranial exostosis, ballooned osteoma, epidermal cyst, and lipoma. Simple radiography, ultrasonography, and computed tomography (CT) were used to make a confirmative diagnosis. Histopathological findings showed lamellated bony structures with poor vascularization. Ostectomy was performed for 5 patients, and no recurrence was detected within an average of 13.4 months after treatment. This review characterized button osteoma. Surgical excision is a useful therapeutic modality after CT-based diagnosis. Further studies with more patients are required to confirm the findings.

    We present our experience in the management of choledochal cysts from 1999 to 2009. A retrospective review of all charts with a diagnosis of choledochal cysts in our institution in this ten-year period. Data was collated using Excel. A total of 17 patients were diagnosed with choledochal cyst: 9 females and 8 males. The average age at diagnosis was 28 months (range from 0 to 9 years). The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates.

  16. Prospects for pulsed power above ten megamperes

    Systems, such as Shiva Star, Atlas and magnetic-flux compression generators, that can deliver several megajoules at currents above 10 MA, offer the opportunity for many interesting experiments in controlled fusion technology and basic material dynamics. Typical current rise-times of a few microseconds result, even with low inductance (<20 nH) circuitry, because several megajoules are delivered at less than 200 kV. This means that conductor surfaces can move significantly relative to the skin-layer thickness, and surface plasmas can interfere with power flow. Success with such multi- megampere technology, therefore, requires considerable attention to the detailed design of joints and conductor surfaces. The paper discusses these and other design considerations. It also describes opportunities enabled by operation above 10 MA. (12 refs).

    Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are severe mucocutaneous eruptions. There is currently no defined optimal approach to wound care. The objective of this study was to evaluate silver dressings in the wound-care management of TEN and SJS/TEN syndrome overlap with a retrospective case review of nine patients with TEN and SJS/TEN overlap presenting to our institution. Nanocrystalline silver dressings appear to be useful in the rapid commencement of healing in these patients. TEN and SJS/TEN overlap are rare conditions. This contributed to a relatively small number of cases included in the study. The ease of application, antimicrobial properties and low frequency of change make nanocrystalline silver dressings ideal in TEN/SJS.

    Multiple and inappropriate medications are often the cause for poor health status in the elderly. Medication reviews can improve prescribing. This study aimed to determine if a ten minute medication review by a general practitioner could reduce polypharmacy and inappropriate prescribing in elderly patients. A prospective, randomised study was conducted. Patients over the age of 65 (n = 50) underwent a 10-minute medication review. Inappropriate medications, dosage errors, and discrepancies between prescribed versus actual medication being consumed were recorded. A questionnaire to assess satisfaction was completed following review. The mean number of medications taken by patients was reduced (p < 0.001). A medication was stopped in 35 (70%) patients. Inappropriate medications were detected in 27 (54%) patients and reduced (p < 0.001). Dose errors were detected in 16 (32%). A high level of patient satisfaction was reported. A ten minute medication review reduces polypharmacy, improves prescribing and is associated with high levels of patient satisfaction.

    How did the universe begin? Where do galaxies come from? How do stars and planets form? Where do the material particles we are made of come from? How did life begin? Today we have only provisional answers to such questions. But scientific progress will improve these answers dramatically over the next ten years, predicts John Gribbin in this riveting book. He focuses on what we know—or think we know—about ten controversial, unanswered issues in the physical sciences and explains how current cutting-edge research may yield solutions in the very near future. With his trademark facility for engaging readers with or without a scientific background, the author explores ideas concerning the creation of the universe, the possibility of other forms of life, and the fate of the expanding cosmos. He examines “theories of everything,” including grand unified theories and string theory, and he discusses the Big Bang theory, the origin of structure and patterns of matter in the galaxies, and dark mass and dark ene...

    Potisk, K P; Gregoric, M; Vodovnik, L

    1995-09-01

    The effect of afferent cutaneous electrical stimulation on the spasticity of leg muscles was studied in 20 patients with chronic hemiplegia after stroke. Stimulation electrodes were placed over the sural nerve of the affected limb. The standard method of cutaneous stimulation, TENS with impulse frequency of 100 Hz, was applied. The tonus of the leg muscles was measured by means of an electrohydraulic measuring brace. The EMG stretch reflex activity of the tibialis anterior and triceps surae muscles was detected by surface electrodes and recorded simultaneously with the measured biomechanical parameters. In 18 out of 20 patients, a mild but statistically significant decrease in resistive torques at all frequencies of passive ankle movements was recorded following 20 min of TENS application. The decrease in resistive torque was often (but not always) accompanied by a decrease in reflex EMG activity. This effect of TENS persisted up to 45 min after the end of TENS. The results of the study support the hypothesis that TENS applied to the sural nerve may induce short-term post-stimulation inhibitory effects on the abnormally enhanced stretch reflex activity in spasticity of cerebral origin.

  10. Comparison of ten packages that compute ocean carbonate chemistry

    Directory of Open Access Journals (Sweden)

    J. C. Orr

    2015-03-01

    Full Text Available Marine scientists often use two measured or modeled carbonate system variables to compute others. These carbonate chemistry calculations, based on well-known thermodynamic equilibria, are now available in a dozen public packages. Ten of those were compared using common input data and the set of equilibrium constants recommended for best practices. Current versions of all 10 packages agree within 0.2 μatm for pCO2, 0.0002 units for pH, and 0.1 μmol kg−1 for CO32− in terms of surface zonal-mean values. That represents more than a 10-fold improvement relative to outdated versions of the same packages. Differences between packages grow with depth for some computed variables but remain small. Discrepancies derive largely from differences in equilibrium constants. Analysis of the sensitivity of each computed variable to changes in each constant reveals the general dominance of K1 and K2 but also the comparable sensitivity to KB for the AT–CT input pair. Best-practice formulations for K1 and K2 are implemented consistently among packages. Yet with more recent formulations designed to cover a wider range of salinity, packages disagree by up to 8 μatm in pCO2, 0.006 units in pH, and 1 μmol kg−1 in CO32− under typical surface conditions. They use different proposed sets of coefficients for these formulations, all of which are inconsistent. Users would do well to use up-to-date versions of packages and the constants recommended for best practices.

    K. G. Pavlakis

    2003-10-01

    Full Text Available Downwelling longwave fluxes, DLFs, have been derived for each month over a ten year period (1984–1993, on a global scale with a resolution of 2.5° × 2.5°.

    The fluxes were computed using a deterministic model for atmospheric radiation transfer, along with satellite and reanalysis data for the key atmospheric input parameters, i.e. cloud properties, and specific humidity and temperature profiles. The cloud climatologies were taken from the latest released and improved International Satellite Climatology Project D2 series. Specific humidity and temperature vertical profiles were taken from three different reanalysis datasets; NCEP/NCAR, GEOS, and ECMWF (acronyms explained in main text. DLFs were computed for each reanalysis dataset, with differences reaching values as high as 30 Wm−2 in specific regions, particularly over high altitude areas and deserts. However, globally, the agreement is good, with the rms of the difference between the DLFs derived from the different reanalysis datasets ranging from 5 to 7 Wm−2. The results are presented as geographical distributions and as time series of hemispheric and global averages. The DLF time series based on the different reanalysis datasets show similar seasonal and inter-annual variations, and similar anomalies related to the 86/87 El Niño and 89/90 La Niña events. The global ten-year average of the DLF was found to be between 342.2 Wm−2 and 344.3 Wm−2, depending on the dataset. We also conducted a detailed sensitivity analysis of the calculated DLFs to the key input data. Plots are given that can be used to obtain a quick assessment of the sensitivity of the DLF to each of the three key climatic quantities, for specific climatic conditions corresponding to different regions of the globe. Our model downwelling fluxes are validated against available data from ground-based stations distributed over the globe, as given by the Baseline

  18. Using TENS for pain control: the state of the evidence.

    Vance, Carol G T; Dailey, Dana L; Rakel, Barbara A; Sluka, Kathleen A

    2014-05-01

    Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacological intervention that activates a complex neuronal network to reduce pain by activating descending inhibitory systems in the central nervous system to reduce hyperalgesia. The evidence for TENS efficacy is conflicting and requires not only description but also critique. Population-specific systemic reviews and meta-analyses are emerging, indicating both HF and LF TENS being shown to provide analgesia, specifically when applied at a strong, nonpainful intensity. The purpose of this article is to provide a critical review of the latest basic science and clinical evidence for TENS. Additional research is necessary to determine if TENS has effects specific to mechanical stimuli and/or beyond reduction of pain and will improve activity levels, function and quality of life.

    Full Text Available Surface tension knowledge of surfactants aqueous solutions is important during amphiphilic molecule manufacturing and new product development, as feedback information to handle synthesis parameters to target performance. Drop counting method is an interesting simplification of drop weight method for surface tension measurements. A simple laboratory measurement device, with capability for temperature control, was assembled to allow investigation of ethoxylated surfactants. The implementation of the method was preceded by a detailed investigation of two factors that may affect the measured surface tension: drop formation velocity and surfactant ethoxylation degree. The limitations of the method are discussed on this basis.

  20. Surface diffusivity of atomic deuterium on Ni3(Al, Ti)(110) surface with and without boron

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The electron-stimulated desorption was used to measure the surface diffusivity of at omic deuterium on clean and boron-modified Ni3(Al, Ti)(110) surfaces. Boron dosing was performed using a solid-state boronion source. Earlier studies showed that boron dissociates water readily at temperatures as low as 130 Kand that the resulting atomic hydrogen is bound to the surface strongly. The surface diffusi on coefficient of atomic D on 0.05 monolayer boron-modified surface was measured to be about 10 times smaller than that on the clean surface. This slower diffu sion of atomic hydrogen may explain why boron improves the ductility of polycrys talline Ni3Al in moist environments.

    Mannheimer, C; Carlsson, C A; Vedin, A; Wilhelmsson, C

    1986-09-01

    The aim of this study was to determine the efficacy of transcutaneous electrical nerve stimulation (TENS) in the treatment of chronic stable severe angina pectoris. In a short-term study the effect of TENS was studied in 10 male patients with angina pectoris (functional class III and IV). All patients had previously been stabilized on long-term maximal oral treatment. The effects of the treatment were measured by means of repeated bicycle ergometer tests. All patients had an increased working capacity (16-85%), decreased ST segment depression and reduced recovery time during TENS. No adverse effects were observed. A long-term study of TENS on similarly selected patients showed beneficial effects in terms of pain reduction, reduced frequency of anginal attacks, increased physical activity and increased working capacity during bicycle ergometer tests. An invasive study was carried out with respect to systemic and coronary hemodynamics and myocardial metabolism during pacing provoked myocardial ischemia in 13 patients. The results showed that TENS led to an increased tolerance to pacing, improved lactate metabolism, less pronounced ST segment depression. A drop in systolic blood pressure during TENS treatment at identical pacing rates indicated a decreased afterload. An increased coronary flow to ischemic areas in the myocardium was supported by the fact that the rate pressure product during anginal pain increased during TENS.

  12. An assessment of ten ocean reanalyses in the polar regions

    Uotila, Petteri

    2017-04-01

    Ocean reanalysis (ORA) combines observations either statistically or with a hydrodynamical model, to reconstruct historical changes in the ocean. Global and regional ORA products are increasingly used in polar research, but their quality remains to be systematically assessed. To address this, the Polar ORA Intercomparison Project (PORA-IP) has been established following on from the ORA-IP project (Balmaseda et al. 2015, with other papers in a special issue of Climate Dynamics). The PORA-IP is constituted under the COST EOS initiative with plans to review reanalyses products in both the Arctic and Antarctic, and is endorsed by YOPP - the Year of Polar Prediction project. Currently, the PORA-IP team consists of 21 researchers from 15 institutes and universities. The ORA-IP products with polar physics, such as sea ice, have been updated where necessary and collected in a public database. In addition to model output, available observational polar climatologies are collected and used in the assessments. Due to the extensive variety of products, this database should become a valuable resource outside the PORA-IP community. For a comprehensive evaluation of the ten ORA products (CGLORSv5, ECDA3.1, GECCO2, Glorys2v4, GloSea5_GO5, MOVEG2i, ORAP5, SODA3.3.1, TOPAZ4 and UR025.4) in the Arctic and Southern Oceans several specific diagnostics are assessed. The PORA-IP diagnostics target the following topics: hydrography; heat, salinity and freshwater content; ocean transports and surface currents; mixed layer depth; sea-ice concentration and thickness; and snow thickness over sea ice. Based on these diagnostics, ORA product biases against observed data and their mutual spread are quantified, and possible reasons for discrepancies discussed. So far, we have identified product outliers and evaluated the multi-model mean. We have identified the importance of the atmospheric forcing, air-ocean coupling protocol and sea-ice data assimilation for the product performance. Moreover, we

    Conducting mail surveys can result in nonresponse error, which occurs when the potential participant is unwilling to participate or impossible to contact. Nonresponse can result in a reduction in precision of the study and may bias results. The purpose of this paper is to describe and make readers aware of a top ten list of mailed survey problems affecting the response rate encountered over time with different research projects, while utilizing the Dillman Total Design Method. Ten nonresponse error problems were identified, such as inserter machine gets sequence out of order, capitalization in databases, and mailing discarded by postal service. These ten mishaps can potentiate nonresponse errors, but there are ways to minimize their frequency. Suggestions offered stem from our own experiences during research projects. Our goal is to increase researchers' knowledge of nonresponse error problems and to offer solutions which can decrease nonresponse error in future projects.

  16. Amplitudes and Correlators to Ten Loops Using Simple, Graphical Bootstraps

    CERN Document Server

    Bourjaily, Jacob L; Tran, Vuong-Viet

    2016-01-01

    We introduce two new graphical-level relations among possible contributions to the four-point correlation function and scattering amplitude in planar, maximally supersymmetric Yang-Mills theory. When combined with the rung rule, these prove powerful enough to fully determine both functions through ten loops. This then also yields the full five-point amplitude to eight loops and the parity-even part to nine loops. We derive these rules, illustrate their applications, compare their relative strengths for fixing coefficients, and survey some of the features of the previously unknown nine and ten loop expressions. Explicit formulae for amplitudes and correlators through ten loops are available at: http://goo.gl/JH0yEc.

    2015-05-15

    Compared to periodic crystals, quasicrystals have higher point group symmetry and are more favorable in achieving complete band-gaps. In this report, a top-cut prism interferometer is designed to fabricate ten-fold photonic quasicrystalline structures. By optimizing the exposing conditions and material characteristics, appropriate quasicrystals have been obtained in the SU8 photoresist films. Atomic Force Microscopy and laser diffraction are used to characterize the fabricated structures. The measurement results show the consistence between the theoretical design and experiments. This will provide guidance for the large-area and fast production of ten-fold quasicrystalline structures with high quality.

    We present here the fundamental parameters of ten open star clusters, nominated from Kronberger et al. (2006) who presented some new discovered stellar groups on the basis of 2MASS photometry and DSS visual images. Star counts and photometric parameters (radius, membership, distances, color excess, age, luminosity function, mass function, total mass, and the dynamical relaxation time) have been determined for these ten clusters for the first time. In order to calibrate our procedures, the main parameters (distance, age, and color excesses) have been re-estimated for another five clusters, which are studied by Kronberger et al. (2006) as well.

    1986-01-01

    The development and computational implementation of analytical expres­ sions for the low-order derivatives of electronic energy surfaces and other molecular properties has undergone rapid growth in recent years. It is now fairly routine for chemists to make use of energy gradient information in locating and identifying stable geometries and transition states. The use of second analytical derivative (Hessian or curvature) expressions is not yet routine, and third and higher energy derivatives as well as property (e.g., dipole moment, polarizability) derivatives are just beginning to be applied to chemical problems. This NATO Advanced Research Workshop focused on analyzing the re­ lative merits of various strategies for deriving the requisite analyti­ cal expressions, for computing necessary integral derivatives and wave­ function parameter derivatives, and for efficiently coding these expres­ sions on conventional scalar machines and vector-oriented computers. The participant list contained many scientist...

    Roots of Helleborus bocconei Ten. subsp. siculus (Schiffner) Merxm. & Podl. are widely used in veterinary folk medicine in Sicily (Italy) to diagnose and cure lower respiratory tract infections in cattle. This study intended to evaluate the in vitro antibacterial activity of the methanolic root extract of Helleborus bocconei Ten. subsp. siculus, and of the bufadienolide and ecdysteroid fractions extracted from its roots, against strains belonging to species commonly associated with respiratory tract infections. The phytochemical screening of the previously prepared plant extracts was carried out by chemical, thin-layer chromatography and spectroscopic methods. The in vitro antibacterial activity of the extracts against seven different standard bacterial strains was evaluated by broth microdilution. According to the present study, Helleborus bocconei Ten. subsp. siculus roots contain bufadienolides and ecdysteroids, and the extracts containing these compounds, as well as the crude methanolic root extract, show antibacterial activity against microorganisms responsible for respiratory infections. In particular, the bufadienolide extract has the highest inhibitory activity against all the tested organisms, and, as the other extracts, shows the lowest MIC values (100mug/ml) against Moraxella catarrhalis and Streptococcus pneumoniae. Since the roots of Helleborus bocconei Ten. subsp. siculus contain substances with antibacterial activity, the traditional use of this plant may also derive from its antibacterial properties.

    Our long term aim is to derive model-independent stellar masses and distances for long period massive binaries by combining apparent astrometric orbit with double-lined radial velocity amplitudes (SB2). We follow-up ten O+O binaries with AMBER, PIONIER and GRAVITY at the VLTI. Here, we report about 130 astrometric observations over the last 7 years. We combine this dataset with distance estimates to compute the total mass of the systems. We also compute preliminary individual component masses for the five systems with available SB2 radial velocities. Nine over the ten binaries have their three dimensional orbit well constrained. Four of them are known colliding wind, non-thermal radio emitters, and thus constitute valuable targets for future high angular resolution radio imaging. Two binaries break the correlation between period and eccentricity tentatively observed in previous studies. It suggests either that massive star formation produce a wide range of systems, or that several binary formation mechanisms ...

    Panagakos, George; Psaraftis, Harilaos N.

    "Green corridors‟ is a concept introduced by the European Commission to enhance the provision of sustainable freight transport logistics services by concentrating freight traffic between major hubs and by relatively long distances. SuperGreen, a Coordination and Support Action aiming at further...... defining this concept, identified the characteristics that distinguish a green corridor from an otherwise efficient one. The main thesis of this paper is that the „core network corridors‟ of the new TEN-T guidelines exhibit all these qualities and the vision of a green corridor network in Europe is close...... to reality. To support this thesis, and in continuation of the work of SuperGreen, the paper examines the proposed new „guidelines‟ for the development of the TEN-T after presenting a brief history of transport network development in Europe....

  11. Team learning in medical education: initial experiences at ten institutions.

    In the midst of curricular reforms that frequently call for reducing lectures and increasing small-group teaching, there is a crisis in faculty time for teaching. This paper describes the initial experiences of ten institutions with team learning (TL), a teaching method which fosters small-group learning in a large-class setting. After initial pilot studies at one institution, nine additional institutions implemented TL in one or more courses. Within 18 months, TL has been used in 40 courses (from.5% to 100% of the time) and all ten institutions will increase its use next year. We surmise that this relatively rapid spread of TL into the medical curriculum is due to the sound pedagogy and efficiency of TL as well as the modest financial resources and support we have provided to partner institutions.

  12. Non-pharmacological treatments for pain relief: TENS and acupuncture.

    Coutaux, Anne

    2017-02-20

    Acupuncture and transcutaneous electrical nerve stimulation (TENS) are non-pharmacological methods that have been used for millennia to relieve pain. As with all complementary treatments, efficacy evaluations face two hurdles: the non-feasibility of double-blinding and the difficulty in identifying the optimal control population or treatment. Nevertheless, recent studies of good methodological quality have demonstrated benefits in many types of pain compared to conventional treatment. The mechanisms of action of acupuncture and TENS, which are increasingly well understood, involve endogenous pain control systems, cerebral plasticity, and nonspecific effects (e.g., expectations and placebo effect). No serious adverse effects have been reported. These data support the more widespread use of non-pharmacological pain management, most notably in patients with chronic pain inadequately relieved by medications alone.

    The present study investigated the difference in blood glucose concentration (Glu) response during an incremental swimming test before and after a ten-week training period and verified whether blood glucose threshold (GT) could be determined in competitive swimmers. 7 elite male university swimmers participated in this study. 2 incremental swimming tests were conducted in a swimming flume before and after a ten-week training period. Blood lactate concentration (Bla) and Glu were measured after each swimming step, and the velocities of the lactate threshold (VLT) and glucose threshold (VGT) were analyzed. VLT increased significantly after training (1.21±0.06 m x s(-1) pre-training, 1.31±0.10 m x s(-1) post-training, pswimming intensity steps. GT was not determined at each trial. Our results show that lactate threshold (LT) improved significantly after the ten-week training period, while the Glu response during incremental swimming tests did not change. Therefore, GT could not be determined in elite competitive swimmers before and after training. Georg Thieme Verlag KG Stuttgart · New York.

    Logic and technical subjects require students to understand basic knowledge in mathematic. For instance, addition, minus, division and multiplication operations need to be mastered by students due to mathematic complexity as the learning mathematic grows higher. Weak foundation in mathematic also contribute to high failure rate in mathematic subjects in schools. In fact, students in primary schools are struggling to learn mathematic because they need to memorize formulas, multiplication or division operations. To date, this study will develop a puppet prototyping for learning mathematic for six to ten digits multiplication. Ten participants involved in the process of developing the prototype in this study. Students involved in the study were those from the intermediate class students whilst teachers were selected based on their vast knowledge and experiences and have more than five years of experience in teaching mathematic. Close participatory analysis will be used in the prototyping process as to fulfil the requirements of the students and teachers whom will use the puppet in learning six to ten digit multiplication in mathematic. Findings showed that, the students had a great time and fun learning experience in learning multiplication and they able to understand the concept of multiplication using puppet. Colour and materials of the puppet also help to attract student attention during learning. Additionally, students able to visualized and able to calculate accurate multiplication value and the puppet help them to recall in multiplying and adding the digits accordingly.

    Evaluation and reduction of dose are important issues. Since cone beam CT (CBCT) has been established now not just in dentistry, the number of acquired examinations continues to rise. Unfortunately, it is very difficult to compare the doses of available devices on the market owing to different exposition parameters, volumes and geometries. The aim of this study was to evaluate the spans of effective doses (EDs) of ten different CBCT devices. 48 thermoluminescent dosemeters were placed in 24 sites in a RANDO(®) head phantom. Protocols with lowest exposition parameters and protocols with highest exposition parameters were performed for each of the ten devices. The ED was calculated from the measured energy doses according to the International Commission on Radiological Protection 2007 recommendations for each protocol and device, and the statistical values were evaluated afterwards. The calculation of the ED resulted in values between 17.2 µSv and 396 µSv for the ten devices. The mean values for protocols with lowest and highest exposition parameters were 31.6 µSv and 209 µSv, respectively. It was not the aim of this study to evaluate the image quality depending on different exposition parameters but to define the spans of EDs in which different CBCT devices work. There is a wide span of ED for different CBCT devices depending on the selected exposition parameters, required spatial resolution and many other factors.

    Full Text Available Macular amyloidosis is an important cause for cutaneous pigmentation, the aetiology of which is poorly understood. Friction has recently been implicated the causation of early lesions, referred to as frictional amyloidosis. Confirmation of diagnosis by the detect on of amyloid using histochemical stains is inconsistent. Ten patients with pigmentation suggestive of macular amyloidosis were studied with detailed history, clinical examination, biopsy for histochemistry and electron microscopy. Nine out of ten patients had a history of prolonged friction with various objects such as bath sponges, brushes, towels, plant sticks and leaves. Amyloid was demonstrated by histochemical staining in only six out of ten cases. In the remaining four cases, amyloid was detected by electron microscopy. These consisted of aggregates of non-branching, extracellular, intertwining fibres measuring between 200-500 nm in length and between 20-25 nm in diameter. The study confirms the role of friction in the causation of this condition. Histochemical stains are not always successful in the detection of amyloid and electron microscopy is helpful for confirming its presence. The term frictional amyloidosis aptly describes the condition.

    A unified field theory in ten dimensions, of all interactions, can describe high energy processes occuring in the early universe. In such a theory transitions that give properties of the universe can occur due to the presence of algebraic and geometric structures. A correspondence between theory and observations of the universe is made, to obtain a new interpretation and properties. This paper consists of a field theory and cosmological model of dark and normal energy and matter, cosmological constant, acceleration and inflation in the early universe.

    While forensic laboratories are coming under increasing pressure to provide meaningful estimates of measurement uncertainty, there has been little discussion of this topic in the literature. This article summarizes ten bases for estimating this parameter: (1) proficiency tests; (2) readability limits; (3) independent reference materials; (4) operational limits applied during calibration; (5) expert judgment; (6) precision control samples without (6) and with (7) contributions from extramural sources of error; (8) error budgets; (9) historical performance; and (10) ruggedness tests. Based on the assumptions underlying each approach, the forensic community will need to apply a variety of discipline-specific approaches to arrive at satisfactory estimates of measurement uncertainty.

    In 1990, DOE initiated a nationwide evaluation of its Weatherization Program, with assistance from Oak Ridge National Laboratory and an advisory group of 40 weatherization professionals, program managers, and researchers. The evaluation is comprised of three impact studies covering the Program`s major market segments: Single-family homes, mobile homes, and dwellings in small (2 to 4-unit) multifamily buildings (the Single-Family Study), Single-family homes heated primarily with fuel oil (the Fuel-Oil Study), and Dwellings in buildings with five or more units (the Multifamily Study). The Single-Family Study, the subject of this report, is a critical part of this coordinated evaluation effort. Its focus on single-family dwellings, mobile homes, and dwellings in small multifamily buildings covers 83% of the income-eligible population and 96% of the dwellings weatherized during Program Year 1989. The first phase of the Single-Family Study involved the analysis of a massive data base of information collected from 368 local weatherization agencies and 543 electric and gas utilities. This analysis resulted in energy-saving and cost-effectiveness estimates for the Weatherization Program and the identification of a set of ten high-performing agencies located throughout the country. The second phase, which is the subject of this report, involves a ``process`` evaluation of these ten high performers, aimed at identifying those weatherization practices that explain their documented success.

    This paper addresses the results of two samples of a large naturalistic (effectiveness study) outpatient process-outcome study in Switzerland (Practice-Oriented Outpatient Psychotherapy Study). Ten different types of psychotherapy were investigated by looking at the role of the sex or gender of therapists and patients with regard to treatment outcome by including several nonspecific therapeutic factors. Ten different types of psychotherapy, 237 patients, and 68 therapists were included in the study. A subsample of 116 cases was analyzed with regard to therapists' technical interventions. Sex and gender issues of both therapists and patients did not play a crucial role in any type of psychotherapy investigated. Gender issues appeared to play an indirect role. Female therapists intervene more empathically, whereas male therapists tend to use more confrontational techniques. Since the results show that therapists differ substantially with regard to their intervention techniques due to their sex, they should become more conscious of their interventions by considering patients' severity of psychological problems and patients' level of psychological functioning so as to not over or underchallenge them.

    Colovesical fistula (CVF) resulting from colon diverticulosis is a comparatively rare disease, and neither the diagnosis nor treatment has been established. Our experience with CVF due to sigmoid diverticulitis over a 9-year period was reviewed to clarify the clinical presentation and diagnostic confirmation. Ten patients with CVF were identified in this period, and chief complaints, laboratory findings, presenting symptoms, diagnostic investigations, and subsequent treatments were reviewed. Preoperative urinalysis showing bacteriuria (100%) was the most common presentation, followed by fecaluria (40%), abdominal pain (40%), pneumaturia (30%), hematuria (30%), pain on urination (30%), pollakiuria (10%), and dysuria (10%). The abilities of various preoperative investigations to identify CVF were: computed tomography (CT), 88.9%; magnetic resonance imaging, 40%; cystoscopy, 30%, and gastrografin irrigoscopy, 22.2%. Colonoscopy (0%) was not diagnostic. Bowel resection was performed in nine of ten patients. When inflammation was intense, covering ileostomy was performed, and an omental plasty was placed between the bowel anastomosis and bladder. When CVF is suspected, we recommend CT followed by colonoscopy and cystoscopy as a first-line investigation to rule out malignancy as a cause. Other modalities should only be used if the diagnosis is in doubt or additional information is needed to plan operative management. Primary colic anastomosis appears to be safely performed by applying omental plasty and covering ileostomy.

    Full Text Available Abstract Background All investigators seeking funding to conduct implementation research face the challenges of preparing a high-quality proposal and demonstrating their capacity to conduct the proposed study. Applicants need to demonstrate the progressive nature of their research agenda and their ability to build cumulatively upon the literature and their own preliminary studies. Because implementation science is an emerging field involving complex and multilevel processes, many investigators may not feel equipped to write competitive proposals, and this concern is pronounced among early stage implementation researchers. Discussion This article addresses the challenges of preparing grant applications that succeed in the emerging field of dissemination and implementation. We summarize ten ingredients that are important in implementation research grants. For each, we provide examples of how preliminary data, background literature, and narrative detail in the application can strengthen the application. Summary Every investigator struggles with the challenge of fitting into a page-limited application the research background, methodological detail, and information that can convey the project’s feasibility and likelihood of success. While no application can include a high level of detail about every ingredient, addressing the ten ingredients summarized in this article can help assure reviewers of the significance, feasibility, and impact of the proposed research.

    Full Text Available One way of boosting cocoa productivity which has plummeted over the last decade in Côte d’Ivoire is to introduce high performing clones. Preliminary observations have indicated that these new clones have differing growth patterns and agronomic traits in the field. Assessing their compatibility is of paramount importance since these clones will be made available to the farmers in the near future. This study was conducted in Soubré, southwest of Côte d’Ivoire, to evaluate the compatibility of ten new cocoa clones (coded as C1, C8, C9, C14, C15, C16, C17, C18, C20, and C21. A half diallel design consisting of 10 self-pollinations and 45 inter-crosses, replicated three times, was used. Results showed significant differences among clones for pollination success. Out of the ten clones evaluated, six (C1, C8, C9, C15, C17 and C21 were self-compatible. With a 39% mean pollination success, C9 was quite interesting because it has been reported to be among the highest yielding clones. Introduction of improved germplasm will go a long way towards enhancing productivity in Côte d’Ivoire, radically impact farmers’ livelihoods, and contribute significantly to a more reliable supply of cocoa beans for chocolate manufacturers.

    Carbon monoxide (CO) is one of the several air pollutants that are largely produced by anthropogenic activities in urban areas as a result of incomplete combustion of carbon-containing fuels. Long-term satellite data can monitor spatial and temporal changes in CO globally. Here we investigated spatial, vertical, and temporal changes in CO concentrations over the largest ten US metropolitan statistical areas (MSAs) using Version 6 MOPITT TIR-only CO retrievals. The 15-year average of MOPITT Surface CO concentrations over urban areas were highest (388 ppbv) over New York City and lowest (151 ppbv) over Miami. The influence of cities on elevated CO levels extends well beyond the immediate urban area. The CO seasonal profiles above the surface show distinct seasonality with peaks March-April and troughs September-October. However, larger cities show a lack of CO seasonality near the surface. We applied the nonparametric Seasonal Kendall (SK) trend test to the CO time series. Results revealed significant decreasing trends in CO concentration, with stronger trends in the lower atmosphere (>700 hPa) than in the mid-troposphere (500-700 hPa). Our results demonstrate the strong influence of local urban emissions on (near-) surface CO concentrations. Decreasing urban CO over the past 15 years reflects improved urban metabolism through improved energy efficiency, and increasing use of alternative transportation and zero-emission vehicles.

It is shown that causality is from small to safe haven towealth, and that theoretically equilibriums are likely to exist where a certain regulation is substantially lower in a small country than in its big neighbor. This generates a large capital inflow to the safe havens. The pool of funds that may reach the safe havens is shown to be huge. It is far in excess of the absorptive capacity of the safe havens, but it still explains, why they are rich. Microstates offer a veil of anonymity to funds passing through, and Switzerland offers safe storage of funds.

  20. Ten common mistakes in designing biodiversity indicators for forest policy.

    Science.gov (United States)

    Failing, Lee; Gregory, Robin

    2003-06-01

    This paper identifies 10 common 'mistakes' in developing and using forest biodiversity indicators from the standpoint of making better forest management choices. The mistakes relate to a failure to clarify the values-basis for indicator selection and a failure to integrate science and values to design indicators that are concise, relevant and meaningful to decision makers. The combined effects of these ten mistakes include inconsistent and indefensible on-ground management strategies and hidden trade-offs at a policy level. They result in frustrated professionals, a confused public, an inability to assess performance with respect to key forest policy objectives and, almost certainly, types and amounts of biodiversity conservation that fail to achieve either scientifically or socially preferred levels. Correcting the mistakes will help to address these problems and, more generally, recognizes the need to better understand the interface between science, public values, and decision making.

    1994-10-01

    This report describes ten of the most frequent ergonomic problems found in human-computer interfaces (HCIs) associated with complex industrial machines. In contrast with being thought of as ``user friendly,`` many of these machines are seen as exhibiting ``user-hostile`` attributes by the author. The historical lack of consistent application of ergonomic principles in the HCIs has led to a breed of very sophisticated, complex manufacturing equipment that few people can operate without extensive orientation, training, or experience. This design oversight has produced the need for extensive training programs and help documentation, unnecessary machine downtime, and reduced productivity resulting from operator stress and confusion. Ergonomic considerations affect industrial machines in at least three important areas: (1) the physical package including CRT and keyboard, maintenance access areas, and dedicated hardware selection, layout, and labeling; (2) the software by which the user interacts with the computer that controls the equipment; and (3) the supporting documentation.

    2016-02-01

    This paper suggests possible evidence of climate change in Mexico at the watershed level, based solely on historical data. The official Mexican climate dataset was used to find the best set of stations for each watershed. Maximum and minimum temperatures and rainfall in ten watersheds are analyzed from 1970 to 2009. Maximum temperature trends show a significant increment in most of these watersheds. Furthermore, Daily Temperature Range (DTR) exhibits a positive trend (increments), thus implying an increase in temperature extremes. This study also shows that the difference between maximum and minimum monthly temperature trends is negatively correlated with monthly precipitation trends. As a result, land-use and land-cover changes could be the main drivers of climate change in the region.

    Full Text Available The ten lump strategy and reaction schemes are based on the concentration of the various stocks i.e., paraffins, naphthenes, aromatic and aromatic substituent groups (paraffinic and napthenic groups attached to aromatic rings. The developed model has been studied using C++ programming language using Runge-Kutta Fehlberg mathematical method. At a space time of 4.5 s, the gasoline yield is predicted to be 72 mass % and 67 mass % for naphthenic and paraffinic feedstock respectively. Type of feed determines the yield of gasoline and coke. A highly naphthenic charge stock has given the greatest yield of gasoline among naphthenic, paraffinic and aromatic charge stock. In addition to this, effect of space time and temperature on the yield of coke and gasoline and conversion of gas oil has been presented. Also, the effect of catalyst to oil ratio is also taken in studies.

    2016-04-01

    Sustainably managing marine species is crucial for the future health of the human population. Yet there are diverse perspectives concerning which species can be exploited sustainably, and how best to do so. Motivated by recent debates in the published literature over marine conservation challenges, we review ten principles connecting life-history traits, population growth rate, and density-dependent population regulation. We introduce a framework for categorizing life histories, POSE (Precocial-Opportunistic-Survivor-Episodic), which illustrates how a species' life-history traits determine a population's compensatory capacity. We show why considering the evolutionary context that has shaped life histories is crucial to sustainable management. We then review recent work that connects our framework to specific opportunities where the life-history traits of marine species can be used to improve current conservation practices.

    This paper investigates the concern that green buildings may promote energy efficiency and other aspects of sustainability, but not necessarily the health and well-being of occupants through better indoor air quality (IAQ). We ask ten questions to explore IAQ challenges for green buildings as well...... as opportunities to improve IAQ within green buildings and their programs. Our focus is on IAQ, while recognizing that many factors influence human health and the healthfulness of a building. We begin with an overview of green buildings, IAQ, and whether and how green building certifications address IAQ. Next, we...... questions, that can help green buildings to more effectively promote IAQ. This article supports a growing recognition of the importance of IAQ in green buildings, and the opportunities for improvements.

    Full Text Available This paper reviews the results of ten years of support for basic scientific research by the CONACYT. The paper identifies the strongest areas of knowledge in basic science in Mexico and concludes that the institutions where basic science is done are mainly public higher education institutions, followed by also public research centers, while private institutions of higher education and companies carry out almost no research in basic science. Findings show that research on basic science in state universities has grown impressively in recent years, reaching the level of the institutions of higher education of the Federal District. Finally, the implications of these findings as well as the public policies through which support has been granted are discussed.

    2013-01-01

    The accumulation of mass from the interaction process that forms the polar ring galaxies is a factor that favors the conditions necessary to trigger nonthermal nuclear activities.. This fact encouraged the chemical analysis of ten polar ring galaxies. In order to verify the presence of an active nucleus in these galaxias, we built diagnostic diagrams using lines H{\\beta}, [OIII], [HI], H{\\alpha}, [NII], and [SII] and classified the type of nuclear activity. For galaxies that do not show shock, the parameters N2 and O3N2 were also determined. From this sample, we identified seven galaxies with an active nucleus and three that behave as HII regions. One galaxy with an active nucleus was classified as Seyfert. Although our data do not provide a statistically significant sample, we can speculate that polar ring galaxies are a setting conducive to trigger non-thermal nuclear activities.

    2015-03-01

    All known cases of breast cancer in patients with a diagnosis consistent with transgender identification were identified in the Veterans Health Administration (1996-2013). Ten cases were confirmed: seven birth sex females and three birth sex males. Of the three birth sex males, two identified as gender dysphoric male-to-female and one identified as transgender with transvestic fetishism. The birth sex males all presented with late-stage disease that proved fatal, whereas most of the birth sex female transgender veterans presented with earlier stage disease that could be treated. These cases support the importance of screening for breast cancer using standard guidelines in birth sex males and females. Family history of breast cancer should be obtained from transgender people as part of routine care. This report expands the known cases of breast cancer in transgender persons from 5 to 12 (female-to-male) and from 10 to 13 (male-to-female).

    2010-01-01

    Full Text Available This paper gives ten best practices for designing mobile applications that have social-networking functions. The need for such an approach is given by the rapid growth in impor-tance of both social networks and mobile applications. In order to make it easy to follow where the best practices come from, the paper starts with a look at why social networks are more than just a buzz word and at how the field of mobile applications is evolving. It also shows how and why the two fields go together so well. To further make the point, there is a case study of four interesting mobile applications that are textbooks examples of successful applications. The best practices are based on research done for this article and on the extensive knowledge of the author.

    2014-09-01

    Full Text Available Whole trees from energy thinnings constitute one of many forest fuel sources, yet ten widely applied supply chains could be defined for this feedstock alone. These ten represent only a subset of the real possibilities, as felling method was held constant and only a single market (combustion of whole tree chips was considered. Stages included in-field, roadside landing, terminal, and conversion plant, and biomass states at each of these included loose whole trees, bundled whole trees or chipped material. Assumptions on prices, performances, and conversion rates were based on field trials and published literature in similar boreal forest conditions. The economic outcome was calculated on the basis of production, handling, treatment and storage costs and losses. Outcomes were tested for robustness on a range of object volumes (50–350 m3solid, extraction distances (50–550 m and transport distances (10–70 km using simulation across a set of discrete values. Transport was calculated for both a standard 19.5 m and an extended 24 m timber truck. Results showed that the most expensive chain (roadside bundling, roadside storage, terminal storage and delivery using a 19.5 m timber truck at 158 € td−1 was 23% more costly than the cheapest chain (roadside chipping and direct transport to conversion plant with container truck, at 128 € td−1. Outcomes vary at specific object volumes and transport distances, highlighting the need to verify assumptions, although standard deviations around mean supply costs for each chain were small (6%–9%. Losses at all stages were modelled, with the largest losses (23 € td−1 occurring in the chains including bundles. The study makes all methods and assumptions explicit and can assist the procurement manager in understanding the mechanisms at work.

  18. Ten major trends now emerging in the United States

    1978-01-01

    Using a special analytical procedure for tracking and assessing events reported in the nation's newspapers, the Center for Policy Process has identified ten emerging trends in the United States that are having a major impact on all our lives and on all businesses and industries--and especially on the electric utility industry. Although the trends may move in contradictory directions and have different degrees of significance, all have been carefully monitored for a considerable length of time. All are firmly established--and are not to be viewed as the momentary interests of certain radical elements of the population. The ten trends are: the fast-emerging clash between nuclear fuel and coal as an environmental health issue; displacement of racism and sexism by ''ageism'' as society's most prominent anti-discrimination preoccupation, and the complete elimination soon of mandatory retirement; in government and technology, the phenomenon of ''appropriate scale'' replacing economies of scale, emergence of single-issue political organizations; coming-of-age of the recycling ethic; emergence of ''access to capital'' as the new equity issue--the new rights issue; continuing shift from centralization to decentralization; movement of society in the dual directions of high technology/high touch; business' increasing involvement with the well-established accountability trend; and shift from a representative democracy to a participatory democracy--this profound change in American democracy actually began about a decade or so ago.

    Pomegranate (Punica granatum L.) is native to the Mediterranean region and has been used extensively as a medicine in many counties. Hyperoside is known as an important flavonoid with antioxidant activity and anti hypertension effect. Anthocyanins are the active component in several herbal medicines, thus accurate measurement of hyperoside and anthocyanins, along with their degradation indices, is very useful to food technologists and horticulturists. The aim of the current study was to determine the antioxidant capacity as hyperoside and anthocyanin content of ten different Iranian pomegranate cultivars. Spectroscopic analyses of the pomegranate showed Black peel cultivar had the highest hyperoside content (25.93 +/- 2.87, 620.41 +/- 30.32 mg/100 g) in its pulp and peel, respectively. Based on this study, the amounts of anthocyanin in pulp ranged between 1.56 +/- 0.05 and 3.89 +/- 0.07 mg g(-1) which related to Sweet white peel and Sweet alac cultivars, respectively. More over the highest and also the lowest peel anthocyanin contents related to these cultivars. The results revealed that the hyperoside and also anthocyanin peel content of each variety is higher than its pulp content. In addition the potency of black peel (Medicinal pomegranate) and Sweet alac cultivars for prevention of coronary heart disease and hypertension were presented.

    Full Text Available Abstract Background Chaperones (CH play an important role in tumor biology but no systematic work on expressional patterns has been reported so far. The aim of the study was therefore to present an analytical method for the concomitant determination of several CH in human tumor cell lines, to generate expressional patterns in the individual cell lines and to search for tumor and non-tumor cell line specific CH expression. Human tumor cell lines of neuroblastoma, colorectal and adenocarcinoma of the ovary, osteosarcoma, rhabdomyosarcoma, malignant melanoma, lung, cervical and breast cancer, promyelocytic leukaemia were homogenised, proteins were separated on two-dimensional gel electrophoresis with in-gel digestion of proteins and MALDI-TOF/TOF analysis was carried out for the identification of CH. Results A series of CH was identified including the main CH groups as HSP90/HATPas_C, HSP70, Cpn60_TCP1, DnaJ, Thioredoxin, TPR, Pro_isomerase, HSP20, ERP29_C, KE2, Prefoldin, DUF704, BAG, GrpE and DcpS. Conclusions The ten individual tumor cell lines showed different expression patterns, which are important for the design of CH studies in tumor cell lines. The results can serve as a reference map and form the basis of a concomitant determination of CH by a protein chemical rather than an immunochemical method, independent of antibody availability or specificity.

    Moment Tensors (MTs) provide important information for seismotectonic, stress distribution and source studies. It is also important as a real time or near real time information in shakemaps, tsunami warning, and stress transfer. Therefore a reliable and rapid MT computation is a routine task for modern seismic networks with broadband sensors and real-time digital telemetry. In this paper we present the database of Moment Tensor solutions computed during the last ten years in Western Greece by the University of Patras, Seismological Laboratory (UPSL). The data from UPSL broad band network were used together with the ISOLA Moment Tensor inversion package for routine MT calculation. The procedures followed and the comparison of UPSL derived solutions with the ones provided by other agencies for Western Greece region are presented as well. The Moment Tensor database includes solutions for events in the magnitude range 2.8-6.8 and provides a unique insight into the faulting characteristics of Western Greece. Moreover it paves the way for detailed studies of stress tensor and stress transfer. The weak events' Moment Tensor included in UPSL's database are important for the comprehension of local seismotectonics and reveal the role of minor faults, which may be critical in seismic hazard estimation.

    2009-01-01

    Residential styled environments for physically challenged people with neuro disabilities are rapidly replacing the standard institutional skilled nursing home. Ten trends are described that utilize residential design approaches to the physical environment while relying on home-care style methods for service delivery. Combined these two forces create powerful differentiators which make group residential settings more friendly and humane. Northern European, as well as, US best practices and prototypes are described that combine housing with services in a range of contexts. The success of northern Europeans in promulgating models of aging-in-place that keep those at risk more independent in the community or within family settings are remarkable. Topics like the impact of small group living clusters, interior design treatments, access to landscape gardens, life skill management methods, movement systems for circulation and exercise, shared space priorities, unit design trends and innovative care giving techniques are introduced. The focus of the article is on specific practices gleaned from cultures and exemplars that appear to increase autonomy, independence and privacy for those who are threatened because of their disabilities with the loss of these lifestyle attributes. Promising concepts of service organization and community outreach are combined with detailed recommendations that address the need for lift technology and safety features in bathrooms and kitchens.

  6. Ten years of integrated care for the older in France

    2011-12-01

    Full Text Available Background: This paper analyzes progress made toward the integration of the French health care system for the older and chronically ill population. Policies: Over the last ten years, the French health care system has been principally influenced by two competing linkage models that failed to integrate social and health care services: local information and coordination centers, governed by the social field, and the gerontological health networks governed by the health field. In response to this fragmentation, Homes for the Integration and Autonomy for Alzheimer patients (MAIAs is currently being implemented at experimental sites in the French national Alzheimer plan, using an evidence-based model of integrated care. In addition, the state's reforms recently created regional health agencies (ARSs by merging seven strategic institutions to manage the overall delivery of care. Conclusion: The French health care system is moving from a linkage-based model to a more integrated care system. We draw some early lessons from these changes, including the importance of national leadership and governance and a change management strategy that uses both top-down and bottom-up approaches to implement these reforms.

    2011-01-01

    The Holistic System of Care for Native Americans in an Urban Environment is a community-focused intervention that provides behavioral health care, promotes health, and prevents disease. This approach is based on a community strategic planning process that honored Native American culture and relationships. Substance abuse, mental illness, homelessness, poverty, crime, physical illness, and violence are symptoms of historical trauma, family dysfunction, and spiritual imbalance. The holistic model links treatment, prevention, and recovery. The link between prevention and treatment is early intervention. Peer support is the link between treatment and recovery. Recovering individuals serve as role models linking recovery to prevention. Culture and spirituality build a strong and resilient foundation for recovery. This article documents the effectiveness of the holistic model over a ten-year period that it has been implemented at the Family & Child Guidance Clinic of the Native American Health Center in the San Francisco Bay Area. The holistic model has produced statistically significant reductions in substance abuse among adult Native American women, men, reentry, and homeless populations; reductions in substance abuse among Native American adolescents; reductions in HIV/AIDS high-risk behavior among Native American men, women, and adolescents; and decreases in acting out behavior among Native American severely emotionally disturbed children.

    Simpson, R.

    2002-04-01

    The first ten years of the Foothills Model Forest, established in 1992, is reviewed. The model forest has been established to develop sustainable forest management within the broader concept of sustainable development and integrated resource management. The project focuses on issues such as wildlife habits and habitats; biodiversity monitoring; natural disturbance trends and patterns; and socio-economic studies. In Phase One of the Canadian Model Forest Network the Foothills Model Forest focused primarily on conducting world class research to advance the concept of sustainable forest management. Phase Two was devoted to communicating the results of that research, with a strong emphasis on generating baseline awareness of the concept of sustainable forest management and creating public awareness of the project's mandate in Alberta. Work during the next five years is expected to focus on demonstration and implementation of research results to forest managers and practitioners and others with a stake in the continued sustainability of Alberta's forests. The Sustainable Forest Management project shares a common objective with the Alberta Chamber of Resources' Integrated Landscape Management project; both projects recognise that reducing the industrial footprint is key to sustainable development. The emphasis on demonstration and implementation in the third phase of the Foothills Model Forest is expected to ensure continued sustainability of forests, ecosystems, communities and resources, with full recognition of the fact that the goal of sustainable development can be achieved only by full cooperation and integrated action of all stakeholders.

    Angioleiomyoma is a rare, benign smooth muscle tumour arising from the tunica media of small veins and arteries and can occur anywhere in the body. The histological appearances are well documented, but there are relatively few descriptions of the magnetic resonance imaging (MRI) findings. A retrospective study of the clinical presentation, MRI appearances and histological findings of ten angioleiomyomas presenting as extremity soft tissue masses. MRI typically demonstrated a well-defined, oval mass located superficial to the fascia with the commonest sites being the hand (three cases) and ankle/foot (five cases). The lesion was isointense to muscle on T1-weighted spin echo images with heterogeneous increased internal T2W/short tau inversion recovery (STIR) signal intensity, which commonly appeared as multiple linear or branching areas of hyperintensity. Enhancement after IV gadolinium ranged from diffuse to heterogeneous. In a single case, central fat signal intensity was seen, while a further case showed marked T2W/STIR hypointensity due to diffuse hyalinisation within the lesion. This is the largest reported MRI series of extremity musculoskeletal angioleiomyoma. Angioleiomyoma should be considered in the differential diagnosis of a superficial mass in the hand or foot, particularly when characteristic linear or branching hyperintensity is seen on T2W or STIR images.

    Disposable cups can be made from conventional petro-plastics, bioplastics, or paperboard (coated with petro-plastics or bioplastics). This study compared ten life cycle assessment (LCA) studies of disposable cups with the aim to evaluate the robustness of their results. The selected studies have only one impact category in common, namely climate change with global warming potential (GWP) as its category indicator. Quantitative GWP results of the studies were closer examined. GWPs within and across each study show none of the cup materials to be consistently better than the others. Comparison of the absolute GWPs (after correction for the cup volume) also shows no consistent better or worse cup material. An evaluation of the methodological choices and the data sets used in the studies revealed their influence on the GWP. The differences in GWP can be attributed to a multitude of factors, i.e., cup material and weight, production processes, waste processes, allocation options, and data used. These factors basically represent different types of uncertainty. Sensitivity and scenario analyses provided only the influence of one factor at once. A systematic and simultaneous use of sensitivity and scenario analyses could, in a next research, result in more robust outcomes. -- Highlights: • Conflicting results from life cycle assessment (LCA) on disposable cups • GWP results of LCAs did not point to a best or worst cup material. • Differences in GWP results are due to methodological choices and data sets used. • Standardized LCA: transparency of LCA studies, but still different in approaches.

    Open clusters are distributed all across the disk and are convenient tracers of its properties. In particular, outer disk clusters bear a key role for the investigation of the chemical evolution of the Galactic disk. The goal of this study is to derive homogeneous elemental abundances for a sample of ten outer disk OCs, and investigate possible links with disk structures such as the Galactic Anticenter Stellar Structure. We analyse high-resolution spectra of red giants, obtained from the HIRES@Keck and UVES@VLT archives. We derive elemental abundances and stellar atmosphere parameters by means of the classical equivalent width method. We also performed orbit integrations using proper motions. The Fe abundances we derive trace a shallow negative radial metallicity gradient of slope -0.027+/-0.007 dex.kpc-1 in the outer 12 kpc of the disk. The [alpha/Fe] gradient appears flat, with a slope of 0.006+/-0.007 dex.kpc-1 . The two outermost clusters (Be 29 and Sau 1) appear to follow elliptical orbits. Be 20 also ex...

    Honey produced by ten stingless bee species (Melipona crinita, M. eburnea, M. grandis, M. illota, Nannotrigona melanocera, Partamona epiphytophila, Ptilotrigona lurida, Scaptotrigona polystica, Scaura latitarsis, and Tetragonisca angustula) from Peru has been characterized according to traditional physicochemical standards (color and moisture), biochemical components (flavonoids, polyphenols, nitrites, proteins), and bioactive properties (antibacterial activity, antioxidant capacity). Analytical data are also provided for a sample of Apis mellifera and an artificial honey control. For stingless bees, honey color varied between 26 and 150 mm Pfund. M. illota produced the lightest honey, while N. melanocera and T. angustula were the darkest. Moisture varied between 20.8 and 45.8 g water/100 g, confirming higher moisture for stingless bee honey than the A. mellifera honey standard of 20 g water/100 g. Flavonoids varied from 2.6 to 31.0 mg quercetin equivalents/100g, nitrites from 0.30 to 2.88 micromoles nitrites/100 g, polyphenols from 99.7 to 464.9 mg gallic acid equivalents/100g, proteins from 0.75 to 2.86 g/100 g, and the antioxidant capacity from 93.8 to 569.6 micromoles Trolox equivalents/100 g. The minimal inhibitory concentration (MIC) was slightly lower against Staphylococcus aureus (12.5 -50 g/100 mL) than Escherichia coli (50 g/100 mL).

    In this study, we investigated cytohistochemistry, cycle progression, and relative DNA content of the female gametophyte cells of Helleborus bocconei Ten. before and after fertilization process. The early stages of embryo development were also investigated. H. bocconei possesses a monosporic seven-celled/eight-nucleate Polygonum type female gametophyte, characterized by a morpho-functional polarity. The cells of the embryo sac showed abundant reserves of polysaccharides, strongly increasing in the egg cell just before fertilization. With different timing in DNA replication during cell cycle progression, synergids, egg cells, and polar nuclei showed a haploid DNA content at the end of their differentiation, while antipodes underwent three DNA endoreduplication cycles. Programmed cell death symptoms were detectable in synergid and antipodal cells. After double fertilization, the central cell quickly underwent many mitotic cycles forming the endosperm, which exhibited a progressive increase in protein bodies and starch grains. Close to the developing embryo, the endosperm differentiated a well-defined region rich in a fibrillar carbohydrate matrix. The zygote, that does not start immediately to divide after double fertilization, developed in to an embryo that reached the heart stage at fruit maturation time. A weakly differentiated embryo at this time indicates a morpho-physiological dormancy of seeds, as a survival strategy imposed by the life cycle of this plant with seed dispersal in spring and their germination in the following winter.

    Full Text Available The widely held constructivist view of learning advocates student engagement via interactivity. Within the physics education research community, several specific interactive strategies have been developed to enhance conceptual understanding. One such strategy, the Interactive Lecture Demonstration (ILD is designed for large lecture classes and, if measured using specific conceptual surveys, is purported to provide learning gains of up to 80%. This paper reports on learning gains for two different Projects over ten years. In Project 1, the ILDs were implemented from 1999 to 2001 with students who had successfully completed senior high school physics. The learning gains for students not exposed to the ILDs were in the range 13% to 16% while those for students exposed to the ILDs was 31% to 50%. In Project 2, the ILDs were implemented from 2007 to 2009 with students who had not studied senior high school physics. Since the use of ILDs in Project 1 had produced positive results, ethical considerations dictated that all students be exposed to ILDs. The learning gains were from 28% to 42%. On the one hand it is pleasing to note that there is an increase in learning gains, yet on the other, we note that the gains are nowhere near the claimed 80%. This paper also reports on teacher experiences of using the ILDs, in Project 2.

  15. Wikis in education - After ten years of experience

    Full Text Available In the recent ten years, the use of Wikimedia projects in classroom has become a daily necessity. On the Wikiversity subject pages, students can enroll into the seminar schedule, teachers can publish links to their educational resources and instructions, as well as summarize experiences. Students can document their activities on their personal Wikiversity pages, where they can also report about their assignments and exchange information with teachers and their peers. They often use Wikiversity as a sandbox, in order to sketch the encyclopedic entries for Wikipedia. They can link Wikiversity with Wikisource. The latter is a space to which they can upload the literary texts that are found in the national digital library. They can also correct the errors, which have been caused by OCR process, and equip the texts with metadata. Wikis thus force their users to depart from the school “ghetto” and enter the realm of their discipline through the participatory establishment of its sustainable, digital infrastructure. Considering the valuable potential that the wikis have in the context of the paradigm shift, during which competition retreats in favor of the participation and exchange, the article concludes that wikis are still insufficiently represented in the education processes.

    Lateral retinacular release is a useful resource in knee surgery that can be used for disorders of the extensor mechanism. For many years, it was indiscriminately used in the treatment of the various patellofemoral joint alterations, with conflicting functional results. This study aimed to analyze the changes that have occurred in the indications and clinical effectiveness of lateral retinacular release by reviewing the relevant literature of the past ten years, comparing it to the classic literature on the subject. It was found that less extensive releases decompress the lateral patellar facet, helping with pain control, while decreasing the risks of medial subluxation. Nowadays, there is clear evidence for its indication in the lateral patellar hypercompression syndrome associated with anterior knee pain, as long as there is no related instability; furthermore, it will normally play an adjuvant role in extensor mechanism alignment surgeries for cases of recurrent patellar instability. The initial results for symptomatic patellofemoral osteoarthritis are promising when lateral release is combined with cartilage debridement; in total knee replacement, it is more commonly used for the correction of valgus deformity in order to improve the components' congruency. Finally, distinguishing the different patellofemoral joint pathologies is seen as crucial in order to indicate this procedure. Further randomized control trials that compare surgical techniques with long-term results are still needed.

    Full Text Available In my thesis “It could just as well have happened today”: Maj Bylock's Drakskeppstrilogi and historical consciousness in ten- to twelve-year-olds, I provide a textual, thematic analysis of the three novels from 1997–1998. Further, in an empirical study I have documented the reading of Bylock's fictitious, historical trilogy about the Viking era as done by 11-year-old children, whose thematic work and development of a historical consciousness also have been part of the study. This article deals only with the textual analysis aspect, which purpose is to show what in the texts might produce a historical consciousness in children as well as how the characters are portrayed in order for children to identify with them. Two functions of the novels are studied: knowledge and analogy. The focus is on the main character Petite/Åsa and her development with a view to gender, ethnicity and class as seen from an intersectional perspective. I use postcolonial concepts such as diaspora and hybrid identity in order to describe cultural encounters brought on by migration. I portray female characters gaining a higher level of empowerment, a term used by Joanne Brown and Nancy St. Clair. Bylock claims that she is reflecting the present in her historical texts and that this is more straightforwardly achieved when the events are set several hundred years ago. As a result irrelevant details can be removed and the focus be placed on timeless, human phenomena, for instance cultural encounters. In the light of the above and ideas about how best to describe cultural encounters I analyse the cultural contexts in which the main character finds herself focusing on her transition from a girl into a woman and her quest for a multicultural identity. I elaborate on the concepts mentioned in the previous by describing two cultural encounters which provide an analogy with the present.

    Full Text Available Objective: Neurocognitive impairment is commonly reported at onset of psychotic disorders. However, the long-term neurocognitive course remains largely uninvestigated in first episode psychosis (FEP and the relationship to clinically significant subgroups even more so. We report 10 year longitudinal neurocognitive development in a sample of FEP patients, and explore whether the trajectories of cognitive course are related to presence of relapse to psychosis, especially within the first year, with a focus on the course of verbal memory.Method: Forty-three FEP subjects (51% male, 28±9 years were followed-up neurocognitively over five assessments spanning 10 years. The test battery was divided into four neurocognitive indices; Executive Function, Verbal Learning, Motor Speed, and Verbal Fluency. The sample was grouped into those relapsing or not within the first, second and fifth year. Results: The four neurocognitive indices showed overall stability over the ten year period. Significant relapse by index interactions were found for all indices except Executive Function. Follow-up analyses identified a larger significant decrease over time for the encoding measure within Verbal Memory for patients with psychotic relapse in the first year (F (4,38=5.8, p=0.001, η2=0.40Conclusions: Main findings are long-term stability in neurocognitive functioning in first episode psychosis patients, with the exception of verbal memory in patients with psychotic relapse or non-remission early in the course of illness. We conclude that worsening of specific parts of cognitive function may be expected for patients with on-going psychosis, but that most patients should expect no change in cognitive performance during the first 10 years after being diagnosed.

  1. Ten tips for receiving feedback effectively in clinical practice.

    2014-01-01

    Despite being recognized as a fundamental part of the educational process and emphasized for several decades in medical education, the influence of the feedback process is still suboptimal. This may not be surprising, because the focus is primarily centered on only one half of the process - the teachers. The learners are the targets of the feedback process and improvement needs to be shifted. Learners need to be empowered with the skills needed to receive and utilize feedback and compensate for less than ideal feedback delivery due to the busy clinical environment. Based on the available feedback literature and clinical experience regarding feedback, the author developed 10 tips to empower learners with the necessary skills to seek, receive, and handle feedback effectively, regardless of how it is delivered. Although, most of the tips are directed at the individual clinical trainee, this model can be utilized by clinical educators involved in learner development and serve as a framework for educational workshops or curriculum. Ten practical tips are identified that specifically address the learner's role in the feedback process. These tips not only help the learner to ask, receive, and handle the feedback, but will also ease the process for the teachers. Collectively, these tips help to overcome most, if not all, of the barriers to feedback and bridge the gaps in busy clinical practices. Feedback is a crucial element in the educational process and it is shown that we are still behind in the optimal use of it; thus, learners need to be taught how to better receive and utilize feedback. The focus in medical education needs to balance the two sides of the feedback process. It is time now to invest on the learner's development of skills that can be utilized in a busy day-to-day clinical practice.

  2. The ten successful elements of an ambulatory care center.

    Experts in healthcare predict that in the future, over 80% of all care will be provided either in the home or ambulatory care centers. How radiology facilities position themselves for this shifting market is critical to their long-term success, even though it appears there are endless opportunities for providing care in this atmosphere. The ten most critical elements that healthcare providers must address to ensure their preparedness are discussed. Location is critical, particularly since patients no longer want to travel to regional medical centers. The most aggressive providers are building local care centers to serve specific populations. Ambulatory care centers should project a high tech, high touch atmosphere. Patient comfort and the appeal of the overall environment must be considered. Centers need to focus on their customers' needs in multiple areas of care. A quick and easy registration process, providing dressing gowns in patient areas, clear billing functions--these are all important areas that centers should develop. Physicians practicing in the ambulatory care center are key to its overall success and can set the tone for all staff members. Staff members must be friendly and professional in their work with patients. The hours offered by the center must meet the needs of its client base, perhaps by offering evening and weekend appointments. Keeping appointments on schedule is critical if a center wants satisfied customers. It's important to identify the target before developing your marketing plan. Where do your referrals come from? Look to such sources as referring physicians, managed care plans and patients themselves. Careful billing is critical for survival in the ambulatory care world. Costs are important and systems that can track cost per exam are useful. Know your bottom line. Service remains the central focus of all successful ambulatory care center functions.

    Background The climatic and cultural diversity of the Italian Peninsula triggered, over time, the development of a great variety of horse breeds, whose origin and history are still unclear. To clarify this issue, analyses on phenotypic traits and genealogical data were recently coupled with molecular screening. Methodology To provide a comprehensive overview of the horse genetic variability in Italy, we produced and phylogenetically analyzed 407 mitochondrial DNA (mtDNA) control-region sequences from ten of the most important Italian riding horse and pony breeds: Bardigiano, Esperia, Giara, Lipizzan, Maremmano, Monterufolino, Murgese, Sarcidano, Sardinian Anglo-Arab, and Tolfetano. A collection of 36 Arabian horses was also evaluated to assess the genetic consequences of their common use for the improvement of some local breeds. Conclusions In Italian horses, all previously described domestic mtDNA haplogroups were detected as well as a high haplotype diversity. These findings indicate that the ancestral local mares harbored an extensive genetic diversity. Moreover, the limited haplotype sharing (11%) with the Arabian horse reveals that its impact on the autochthonous mitochondrial gene pools during the final establishment of pure breeds was marginal, if any. The only significant signs of genetic structure and differentiation were detected in the geographically most isolated contexts (i.e. Monterufolino and Sardinian breeds). Such a geographic effect was also confirmed in a wider breed setting, where the Italian pool stands in an intermediate position together with most of the other Mediterranean stocks. However, some notable exceptions and peculiar genetic proximities lend genetic support to historical theories about the origin of specific Italian breeds. PMID:27054850

    2003-06-01

    Why Galileo's finger? Galileo, one of whose fingers is preserved in a vessel displayed in Florence, provided much of the impetus for modern science, pointing the way out of medieval ignorance. In this brilliant account of the central ideas of contemporary science, Peter Atkins celebrates the effectiveness of Galileo's symbolic finger for revealing the nature of our universe, our world, and ourselves. Galileo's Finger takes the reader on an extraordinary journey that embraces the ten central ideas of current science. "By a great idea," writes Peter Atkins, "I mean a simple concept of great reach, an acorn of an idea that ramifies into a great oak tree of application, a spider of an idea that can spin a great web and draw in a feast of explanation and elucidation." With wit, charm, and patience, Atkins leads the reader to an understanding of the essence of the whole of science, from evolution and the emergence of complexity, to entropy, the spring of all change in the universe; from energy, the universalization of accountancy, to symmetry, the quantification of beauty; and from cosmology, the globalization of reality, to spacetime, the arena of all action. "My intention is for us to travel to the high ridges of science," Atkins tells us. "As the journey progresses and I lead you carefully to the summit of understanding, you will experience the deep joy of illumination that science alone provides." Galileo's Finger breaks new ground in communicating science to the general reader. Here are the essential ideas of today's science, explained in magical prose.

    The development of alternative approaches in ectoparasite management is currently required. Essential oils have been demonstrated to exhibit fumigant and topical toxicity to a number of arthropods. The aim of the present study was to assess the potential efficacy of ten essential oils against Sarcoptes scabiei. The major chemical components of the oils were identified by GC-MS analysis. Contact and fumigation bioassays were performed on Sarcoptes mites collected from experimentally infected pigs. For contact bioassays, essential oils were diluted with paraffin to get concentrations at 10, 5, and even 1% for the most efficient ones. The mites were inspected under a stereomicroscope 10, 20, 30, 40, 50, 60, 90, 120, 150, and 180min after contact. For fumigation bioassay, a filter paper was treated with 100 μL of the pure essential oil. The mites were inspected under a stereomicroscope for the first 5min, and then every 5min until 1h. Using contact bioassays, 1% clove and palmarosa oil killed all the mites within 20 and 50min, respectively. The oils efficacy order was: clove > palmarosa > geranium > tea tree > lavender > manuka > bitter orange > eucalyptus > Japanese cedar. In fumigation bioassays, the efficacy order was: tea tree > clove > eucalyptus > lavender > palmarosa > geranium > Japanese cedar > bitter orange > manuka. In both bioassays, cade oil showed no activity. Essential oils, especially tea tree, clove, palmarosa, and eucalyptus oils, are potential complementary or alternative products to treat S. scabiei infections in humans or animals, as well as to control the mites in the environment.

  7. The ten deadly mistakes of wanna-dots.

    Increasingly, it seems, there are just two types of companies left in the world: dot-coms, born on the Internet, and "wanna-dots," established organizations that are seeking to incorporate the Internet into their businesses. Some wanna-dots manage the deep mind-shift required to cross the digital divide. These are the pacesetters--the first movers and fast followers that exhibit organizational curiosity and the desire to innovate. But most wanna-dots are laggards; they don't rise to the challenge with the same resolve. In a global research effort involving more than 800 companies, the author uncovered so many wanna-dots making the same kinds of mistakes that it almost seemed they were following a How Not to Change guide. In this article, Kanter creates just such a guide, offering ten pieces of antiadvice that expose the tendency of wanna-dots to make only cosmetic changes when deep transformation is required. Beyond delineating what not to do, Kanter serves up two examples of wanna-dots that got it right. First, Williams-Sonoma, which successfully made up for a slow start to create a strong Web presence. Second, Honeywell, a pacesetter led by e-believers from the start, which still found the road to the Web a challenging one. For companies not born digital, the fundamental problem is change. And the real place to look for change is not on the Internet but inside your company--at your own organizational culture and your attitude toward change.

  8. The management of radioactive waste. A description of ten countries

    The aim of this report is to provide a description of how the responsible authorities/companies in ten EDRAM countries (International Association for Environmentally Safe Disposal of Radioactive Materials) deal with the management of radioactive waste. The focus is on how the responsible organisation currently handles this issue, including technical, economic and socio-political aspects. The material used was primarily produced by the companies/authorities themselves. The report describes the development and situation in each country up to the end of 2001, or later if noted as such in the country report. The scope of this report does not permit an evaluation of how successful and effective the companies and authorities have been in implementing their plans and ambitions. The report does not include the views of other national stakeholders concerning radwaste management, or their opinions of the way that the authorities/companies handle the issue of radwaste. The description is based on a series of questions that were drawn up and discussed at the initial stage of the EDRAM co-operation. Technological aspects: 1. What technology is used? How is research and development promoted and executed? 2. Where is the waste to be put? What criteria does each country search for? 3. How is security to be maintained? Who can obtain a license for handling nuclear waste? Economic aspects: 1. In what way do the countries in question discuss the time aspects as regards delays and similar? 2.

    The aim of this report is to provide a description of how the responsible authorities/companies in ten EDRAM countries (International Association for Environmentally Safe Disposal of Radioactive Materials) deal with the management of radioactive waste. The focus is on how the responsible organisation currently handles this issue, including technical, economic and socio-political aspects. The material used was primarily produced by the companies/authorities themselves. The report describes the development and situation in each country up to the end of 2001, or later if noted as such in the country report. The scope of this report does not permit an evaluation of how successful and effective the companies and authorities have been in implementing their plans and ambitions. The report does not include the views of other national stakeholders concerning radwaste management, or their opinions of the way that the authorities/companies handle the issue of radwaste. The description is based on a series of questions that were drawn up and discussed at the initial stage of the EDRAM co-operation. Technological aspects: 1. What technology is used? How is research and development promoted and executed? 2. Where is the waste to be put? What criteria does each country search for? 3. How is security to be maintained? Who can obtain a license for handling nuclear waste? Economic aspects: 1. In what way do the countries in question discuss the time aspects as regards delays and similar? 2. How are the economic and financial aspects of the process dealt with? Where does the money come from? Socio-political aspects: 4. What role do politicians play and to what extent is social acceptance a part of the process? What part does public opinion play? 5. How flexible is the decision-making process and can decisions be revised? 6. Does the public have confidence in the industry and the decision-makers? 7. What kind of institutional problems arise?

    We investigated the properties of the stellar populations in the discs of a sample of ten spiral galaxies. Our analysis focused on the galaxy region where the disc contributes more than 95 per cent of total surface brightness in order to minimise the contamination of the bulge and bar. The luminosity-weighted age and metallicity were obtained by fitting the galaxy spectra with a linear combination of stellar population synthesis models, while the total overabundance of {\\alpha}-elements over iron was derived by measuring the line-strength indices. Most of the sample discs display a bimodal age distribution and they are characterised by a total [{\\alpha}/Fe] enhancement ranging from solar and supersolar. We interpreted the age bimodality as due to the simultaneous presence of both a young (Age$\\,\\leq\\,4$ Gyr) and an old (Age$\\,>\\,$4 Gyr) stellar population. The old stellar component usually dominates the disc surface brightness and its light contribution is almost constant within the observed radial range. For...

    Full Text Available Commercially available products serve as good examples for the compounding pharmacist to produce quality compounded dosage forms. Their physical and chemical properties, when known, can provide valuable information for preparing similar dosage forms to patients. One of the important physical characteristics of preparations is their specific gravity. The specific gravity is defined as the density of the substance divided by the density of water at a given temperature. We purchased ten non-prescription products from a store in North Carolina. We tested three bottles of each product for their specific gravity using Densito 30PX (Metter Toledo; Switzerland. The instrument is easy to use and allows calibration with a standard liquid (purified water or alcohol, U.S.P. at different temperatures (0oC to 40oC. We measured each bottle of the same product thrice. The following products were tested for their specific gravity at room temperature: Alka-seltzer Plus (Bayer Health Care; Lot#-276698L; Children’s Advil (Wyeth Consumer Healthcare; Lot#-B58397; Children’s Motrin (McNeil Consumer Healthcare; Lot#-ABM011; Children’s Tylenol (McNeil Consumer Healthcare; Lot#-SSM015; Children’s Zyrtec (McNeil Consumer Healthcare; Lot# for bottle 1-809301; Lot# for bottles 2 and 3- 809302; Listerine (Lot#-0619LZ; Oral Health Rinse (TopCare; Lot#-90F1001; Scope (Proctor & Gamble; Lot#-95609187; Theraflu (Novartis Consumer Health; Lot# for bottles 1 and 3-10061769; Lot# for bottle 2-10063059; Tylenol Cold (McNeil Consumer Healthcare; Lot# for bottles 1 and 2-900009; Lot# for bottle 3-808311. The results are summarized in Table 1.

    It has been nearly ten years since the First State of the Carbon Cycle Report (SOCCR-1) was published in 2007. Much has changed in the intervening years, but much has remained the same. In anticipation of a Second State of the Carbon Cycle Report (SOCCR-2), we, the members of the SOCCR-1 Coordinating Team, felt that a perspective from the first SOCCR and reflection on changes in the state of carbon cycle science and policy in the intervening years would be appropriate. The purpose of SOCCR-1 was to provide "…a synthesis and integration of the current knowledge of the North American carbon budget and its context within the global carbon cycle [i]n a format useful to decision makers." Being "useful to decision makers" was a guiding theme with three stakeholder workshops an integral part of the process. Drafting and revision of SOCCR-1 took place between 2005 and early 2007; the report's carbon budget was for circa 2003. In 2003, North America's fossil-fuel CO2 emissions were approximately 27% of global emissions. Nearly 85% of North American emissions were from the US, still at that time the world's largest emitter of fossil-fuel CO2. China's annual CO2 emissions exceeded those of the US for the first time while SOCCR-1 was being written. Today global CO2 emissions are dominated by emissions from China (28% in 2013), with US emissions only 14% of global emissions. Emissions from the US and North America have actually declined by approximately 10% since 2003 while emissions from China have doubled. Based on inventories of terrestrial carbon stocks, SOCCR-1 estimated that circa 2003 North American vegetation removed and stored a net 500 Mt C y-1 (±50%) from the atmosphere. A more recent synthesis incorporating additional estimates from atmospheric inversions and terrestrial biosphere modeling estimated the North American land sink for the decade of 2000-2009 at 350-470 Mt C y-1, with a slightly greater uncertainty due to the wider range of estimates from the

    The MODIS cloud optical properties algorithm (MOD06/MYD06 for Terra and Aqua MODIS, respectively) has undergone extensive improvements and enhancements since the launch of Terra. These changes have included: improvements in the cloud thermodynamic phase algorithm; substantial changes in the ice cloud light scattering look up tables (LUTs); a clear-sky restoral algorithm for flagging heavy aerosol and sunglint; greatly improved spectral surface albedo maps, including the spectral albedo of snow by ecosystem; inclusion of pixel-level uncertainty estimates for cloud optical thickness, effective radius, and water path derived for three error sources that includes the sensitivity of the retrievals to solar and viewing geometries. To improve overall retrieval quality, we have also implemented cloud edge removal and partly cloudy detection (using MOD35 cloud mask 250m tests), added a supplementary cloud optical thickness and effective radius algorithm over snow and sea ice surfaces and over the ocean, which enables comparison with the "standard" 2.1 11m effective radius retrieval, and added a multi-layer cloud detection algorithm. We will discuss the status of the MOD06 algorithm and show examples of pixellevel (Level-2) cloud retrievals for selected data granules, as well as gridded (Level-3) statistics, notably monthly means and histograms (lD and 2D, with the latter giving correlations between cloud optical thickness and effective radius, and other cloud product pairs).

  16. Ten-year results of a comparison of methods for restoring afforested blanket bog

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available There is growing interest in the restoration of blanket bogs that were afforested during the 1960s to 1980s, to avoid further loss of carbon to the atmosphere and to regain and defragment important blanket bog habitat. This paper reports the findings from a ten-year experiment in the UK to test the effectiveness of restoration treatments on water table depth, peat bulk density and water content, ground surface height and vegetation development. Treatments used were the six combinations of damming or not damming plough furrows with leaving the trees alive, felling and leaving them on the ground or felling and removing them. Combining felling with damming furrows was most successful in raising the water table, whether or not the felled trees were removed. Only where felling was combined with damming did the water table continue to recover between Years 5 and 10. Over ten years, the water level in these treatments rose to slightly below that of non-afforested reference bog at the same sites. This occurred as a rapid initial rise, following which there was only very slight further improvement. Felling caused the species composition of the vegetation to change towards that of the reference bogs. The process was slow, with the vegetation becoming more dissimilar to non-forested reference bog in the first five years and then becoming more similar to the reference bog after Year 5. Surprisingly, damming plough furrows had little effect on the vegetation except that, in combination with felling, it increased differentiation between the plough furrows and other positions on the ploughed ground. Conifer seedlings established on the restored plots, most densely where they adjoined standing forest, and had similar density and growth in all the felled treatments. The restoration treatments resulted in a decrease in bulk density and increase in water content of the upper peat, probably due to an unloading effect caused by the raised water table buoying up the

    Full Text Available O presente texto procura discutir o legado deixado pelo sociólogo francês Pierre Bourdieu. Dez anos após sua morte, tem-se discutido, em nível internacional, a relevância deste autor, um dos mais influentes e citados teóricos do mundo. Para a identificação desta influência no Brasil, mais especificamente no campo educacional brasileiro, pesquisou-se nas teses e dissertações encontradas no banco de dados da CAPES, que referenciavam Bourdieu, de que forma estaria se dando a apropriação de seu quadro teórico de análise para construção de conhecimento no referido campo. Concluiu-se que o número de produções defendidas nos Programas de Pós-Graduação em Educação no Brasil, de 1965 a 2010, cresce de forma exponencial, demonstrando o quão profícua a utilização da teoria sociológica de Bourdieu tem se mostrado para explicar a realidade da Educação no Brasil na contemporaneidade. Encerra-se o artigo com uma reflexão sobre a consideração do status de Bourdieu como um clássico da Sociologia que, paradoxalmente, se mostra mais atual e vivo do que qualquer outro autor quando se trata de aplicar seu princípio maior, a saber, analisar o mundo social e suas lógicas, desvelando as formas de dominação e as misérias sociais.This paper's intent is to discuss the legacy left by the French sociologist Pierre Bourdieu. Ten years after his death, it has been discussed at an international level the relevance of this author, one of the most cited and influential theorists in the world. To identify such influence in Brazil, more specifically in the Brazilian educational field, we investigated theses and dissertations found in CAPES database, which referenced Bourdieu, to identify how those works use his theoretical framework of analysis for construction of knowledge in that field. It was concluded that the number of productions held in post-graduate programs in education in Brazil, from 1965 to 2010, grows exponentially

    DNA nanotechnology is currently widely explored and especially shows promises for advanced lithography due to its ability to define nanometer scale features. We demonstrate a 9 × 14 nm(2) hole pattern transfer from DNA origami into an SiO2 layer with a sub-10-nm resolution using anhydrous HF vapor in a semiconductor etching machine. We show that the resulting SiO2 pattern inherits its shape from the DNA structure within a process time ranging from 30 to 60 s at an etching rate of 0.2 nm/s. At 600 s of etching, the SiO2 pattern meets corrosion and the overall etching reaction is blocked. These results, in addition to the entire surface coverage by magnesium occurring on the substrate at a density of 1.1 × 10(15) atom/cm(2), define a process window, fabrication rules, and limits for DNA-based lithography.

    To estimate normative values and repeatability of thresholds for the TEN(HL) test for diagnosing dead regions in the cochlea, as a function of signal frequency, TEN(HL) level, age and gender. The TEN(HL) test was administered twice for each ear of each participant using signal frequencies from 0.5 to 4 kHz and TEN(HL) levels of 30, 50 and 70 dB HL/ERBN. In all, 29 young participants and 8 older participants were tested. All had normal audiograms with no history of hearing problems. There was good repeatability across sessions. There was no significant effect of ear, gender or age group. The average signal-to-TEN ratio (STR) at threshold was close to 0 dB. For low signal frequencies, the STR at threshold varied only slightly with TEN(HL) level, but for the signal frequencies of 3 and 4 kHz the STR at threshold increased to about +2.7 dB for the TEN(HL) level of 70 dB/ERBN. For a high TEN(HL) level, the "normal" STR at threshold at 3 and 4 kHz is closer to +2 dB than to 0 dB. Further research is needed to assess whether the TEN(HL)-test criteria need to be modified when testing at high frequencies and high levels.

  1. Drosophila Ten-m and filamin affect motor neuron growth cone guidance.

    Directory of Open Access Journals (Sweden)

    Lihua Zheng

    Full Text Available The Drosophila Ten-m (also called Tenascin-major, or odd Oz (odz gene has been associated with a pair-rule phenotype. We identified and characterized new alleles of Drosophila Ten-m to establish that this gene is not responsible for segmentation defects but rather causes defects in motor neuron axon routing. In Ten-m mutants the inter-segmental nerve (ISN often crosses segment boundaries and fasciculates with the ISN in the adjacent segment. Ten-m is expressed in the central nervous system and epidermal stripes during the stages when the growth cones of the neurons that form the ISN navigate to their targets. Over-expression of Ten-m in epidermal cells also leads to ISN misrouting. We also found that Filamin, an actin binding protein, physically interacts with the Ten-m protein. Mutations in cheerio, which encodes Filamin, cause defects in motor neuron axon routing like those of Ten-m. During embryonic development, the expression of Filamin and Ten-m partially overlap in ectodermal cells. These results suggest that Ten-m and Filamin in epidermal cells might together influence growth cone progression.

    Ten-a is one of the two Drosophila proteins that belong to the Ten M protein family. This protein is a type Ⅱ transmembrane protein and is expressed mainly in the embryonic CNS, in the larval eye imaginal disc and in the compound eye of the pupa. Here,we investigate the role of ten-a during development of the compound eye by using the Gal4/UAS system to induce ten-a overexpression in the developing eye. We found that overexpression of ten-a can perturb eye development during all stages examined. In an early stage, overexpression of ten-a in eye primordial cells caused small and rough eyes and interfered with photoreceptor cell recruitment, resulting in some ommatidia having fewer or extra photoreceptor cells. Conversely, ten-a overexpression during ommatidial formation caused severe eye defects due to absence of many cellular components. Interestingly,overexpression of ten-a in the late stage developing ommatidial cluster affected the number of pigment cells, caused cone cells proliferation in many ommatidia, and caused some photoreceptor cell defects. These results suggest that ten-a may be a novel gene required for normal eye morphogenesis.

    The performance of ten density functional theory (DFT) methods in a prediction of the structure of four clay minerals, in which non-bonding interactions dominate in the layer stacking (dispersive forces in talc and pyrophyllite, and hydrogen bonds in lizardite and kaolinite), is reported. In a set of DFT methods following functionals were included: standard local and semi-local (LDA, PW91, PBE, and RPBE), dispersion corrected (PW91-D2, PBE-D2, RPBE-D2, and vdW-TS), and functionals developed specifically for solids and solid surfaces (PBEsol and AM05). We have shown that the standard DFT functionals fail in the correct prediction of the structural parameters, for which non-bonding interactions are important. The remarkable improvement leading to very good agreement with experimental structures is achieved if the dispersion corrections are included in the DFT calculations. In such cases the relative error for the most sensitive lattice vector c dropped below 1%. Very good performance was also observed for both DFT functionals developed for solids. Especially, the results achieved with the PBEsol are qualitatively similar to those with DFT-D2.

    Human interleukin-15 (hlL-15) is an important cytokine to activate endothelial cells and can be regulated by many other cytokines. The aim of this study is to examine the ability of interferon-γ,(IFN-γ), and tumor necrosis factor-ct (TNF-α) to induce the production of human interleukin-15 (hlL-15)and IL-15 receptor (IL-15Rα) by human umbilical vein endothelial cells (HUVECs). The data are summarized as follows: 1. Northern blot revealed that IL-15 mRNA was up-regulated by IFN-γ and TNF-α. 2. lntracellular IL-15 protein was visualized by fluorescence microscopy, whereas the expres-sion of IL-15 on the surface of HUVECs was detected by fluorescence activated cell sorting (FACS),and no detectable IL-15 in the medium was verified by ELISA. 3. IL-15Rα was detected on the surface of HUVECs by FACS after IFN-γ and TNF-α stimulation, whereas Western blotting revealed that the elevated expression on surface IL-15Rα was not due to the increased protein expression. The conclusion demonstrated from our results is that IFN-γ and TNF-α play an important role in regulating the expres-sion of IL-15 and IL-15Rα on the surface of HUVECs.

    Full Text Available Transcutaneous Electrical Nerve Stimulation over acupoints (Acu-TENS facilitates recovery of resting heart rate after treadmill exercise in healthy subjects. Its effect on postexercise respiratory indices has not been reported. This study investigates the effect of Acu-TENS on forced expiratory volume in 1 second (FEV1 and forced vital capacity (FVC in healthy subjects after a submaximal exercise. Eleven male subjects were invited to the laboratory twice, two weeks apart, to receive in random order either Acu-TENS or Placebo-TENS (no electrical output from the TENS unit over bilateral Lieque (LU7 and Dingchuan (EX-B1 for 45 minutes, before undergoing exercise following the Bruce protocol. Exercise duration, rate of perceived exertion (RPE, and peak heart rate (PHR were recorded. Between-group FEV1 and FVC, before, immediately after, at 15, 30, and 45minutes postexercise, were compared. While no between-group differences in PHR, RPE, and FVC were found, Acu-TENS was associated with a longer exercise duration (0.9 min (P=.026 and a higher percentage increase in FEV1 at 15 and 45 minutes postexercise (3.3 ± 3.7% (P=.013 and 5.1 ± 7.5% (P=.047, resp. compared to Placebo-TENS. We concluded that Acu-TENS was associated with a higher postexercise FEV1 and a prolongation of submaximal exercise.

    Full Text Available Increased heart rate (HR and reduced blood pressure (BP are common consequences of cardiac surgery. This study investigated the effect of transcutaneous electrical nervous stimulation applied over acupuncture points (Acu-TENS on HR, BP, rate pressure product (RPP and nausea and vomiting score after open-heart surgery. After open heart surgery, 40 patients were randomly allocated to either an Acu-TENS group, which received a 40-min session of TENS applied bilaterally over the acupuncture point PC6 on postoperative days 1–5, or a Placebo-TENS group, which received identical electrode placement but with no electrical output from the TENS unit, despite an output indicator light appearing activated. HR, systolic and diastolic BPs (SBP and DBP were recorded and RPP computed. Nausea and vomiting symptoms were quantified using a 4-point Likert scale before and after TENS intervention. Daily HR, BP and antiemetic administration data were recorded from a further 20 consecutive subjects who received no intervention and formed the Control group. A trend of decreasing HR and increasing BP in the Acu-TENS group was observed over the five postoperative days, with all variables returning to preoperative values by Day 4 (P > .2. In the Placebo-TENS and Control groups the HR remained higher (P < .0001, BP lower (P < .05 and RPP higher (P = .01 than respective preoperative values at Day 4. The dose of Maxolon required was lowest in the Acu-TENS group (P = .038. We concluded that Acu-TENS facilitated an earlier return to preoperative BP, HR and RPP values in patients after acute heart surgery.

    During the recent decade, time-series analysis of Interferometric Synthetic Aperture Radar (InSAR) data has become a powerful tool for long term analysis of sub-centimeter geodynamic deformation signals. While Persistent Scatter InSAR (PSI), one of the currently available InSAR time-series analysis techniques, has been successfully applied to quantify deformation patterns near active volcanoes, its performance has been limited by low densities of phase-stable-points especially near a volcano's caldera. Aside from the presence of a dominant stable scatterer in a SAR resolution cell, the detectability of PS in a stack of SAR data depends on various factors, including the characteristics of the applied selection algorithms, potential seasonal variations of scattering conditions, and the SAR system's observation geometry. Especially in natural environments, the choice of above factors has a significant impact on the achievable density and distribution of PS points. In this paper, we analyze the dependence of PS densities on scene parameters such as surface type, observation geometry, as well as seasonal effects on scattering properties, and propose concepts for PS density maximization All investigations use the Valley of Ten Thousands Smokes (VTTS), as main test site. VTTS is the site of the 1912 eruption of Novarupta Volcano, which altered the area dramatically. Glacial and wind erosion left out barren grounds that potentially contribute to build natural PS. Based on this test site, this paper addresses the following research: Dependence of PS Density on Surface Type: Based on ground truth information of surface types and surface conditions that were acquired in early summer 2011, the dependence of PS density on surface conditions was analyzed. Here, ground truth information was compared to PS distributions in a stack of summer-only C-band SAR scenes. The selection of summer-only data minimizes seasonal effects and maximizes the applicability of the ground truth data

    When hyperthermal atomic oxygen collides with a silicon surface, an ultrathin oxidation regime characterized by fractional atomic-oxygen anions having low diffusive and reactive barriers, along with their enhanced diffusion due to both the electric field and image potential, will form on the surface. In ac- cordance with these properties, an attempt was made in the present study to modify the Almeida- Goncalves-Baumvol (AGB) model by setting the diffusivity and reaction rate constant to be diffu- sion-length dependence. According to the modified model, numerical parametric studies for oxidation thin growth were performed. The dependencies of the diffusion coefficient, the reaction rate constant, the attenuation length, and the adjustable parameter upon the translational kinetic energy, flux, tem- perature, and tangential flux of atomic oxygen were analyzed briefly via the fitting of the experimental data given by Tagawa et al. The numerical results confirmed the rationality of the modified diffu- sion-reaction model. The model together with the computer code developed in this study would be a useful tool for thickness evaluation of the protective film against the oxidation of atomic oxygen toward spacecraft surface materials in LEO environment.

    Objective To delineate the influence of transcutaneous electrical nerve stimulation (TENS) on heat pain threshold and vibration threshold in human.Methods Twenty healthy, young subjects, aged from 20 to 39, participated in the study. They were randomly allocated into either TENS or placebo group. Thirty minutes of conventional TENS (200 μs pulses at 100 Hz and 2-3 times sensory threshold) or placebo stimulation was applied to the acupuncture points (LI4) on each subject's left hand. Heat pain and vibration thresholds were measured using Medoc TSA-2001 and VSA-3000 respectively on the thenar eminence of each subject's left hand. These assessments were done at 30, 20 and 10 minutes before and 0, 10, 20, 30, 40 and 50 minutes after 30 minutes of TENS or placebo treatment.Results This study showed a significant increase in heat pain threshold by 0.81℃ and 1.54℃ respectively at 0 (P=0.002) and 20 minutes (P=0.004) after 30 minutes of TENS application to the LI4 acupoint of young healthy subjects, compared with placebo stimulation. Interestingly, no significant difference in vibration threshold was found between the TENS and placebo groups.Conclusion The effect of TENS on the acupoint is to reduce pain but not tactile (specifically vibration) sensibility.

    Full Text Available Purpose: Unilateral or bilateral testicular pain lasting more than 3 months is called as chronic orchialgia. Aproximately 25-50% of chronic orchialgia is idiopatic origin. This study aimed the effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS therapy due to Idiopathic Chronic Orchialgia (ICO. Methods: Five patients were included into this study with ICO that diagnosed with physical examination, urine analyses, urinary system x-ray film, and scrotal doppler ultrasound. Medical history revealed that multiple conservative therapy attempts failed to alleviate the pain. Two of the patients had right sided ICO. Traditional TENS device is placed to the most painful points. TENS applied 3 times in a week with duration 30 minutes for 4 weeks. Before and after TENS application, patients were evaluated by using Visual Analog Scale (VAS at first and third months. Results: Median age of patients was 26.20±2.38 (22-30. Mean VAS value was 6.52 ± 0.89 before the procedure. After 1 month VAS value was 3.82 ± 0.83 (p0.05. None of the patients needed any analgesics after during the one month. No complications, hyperemia or hypoesthesia of the scrotal or penile skin, occurred after the procedure. Conclusion: TENS reduces pain by increasing endorphin release in the spinal cord dorsal horn. TENS is very effective method for first 1 month in patients with ICO but its effect reduces by the time. There is no standard therapeutic protocol for idiopathic chronic orchialgia. Therefore TENS may be an alternative for patients who do not benefit from medical therapy and do not want invasive procedures. Short-term use of TENS and low number of the patients are the limitations of this study. Randomized, placebo-controlled, and longer follow-up period studies are needed to better assess the efficacy of TENS for ICO.

    Water in different phases under various external conditions is very important in bio-chemical systems and for material science at surfaces. Density functional theory methods and approximations thereof have to be tested system specifically to benchmark their accuracy regarding computed structures and interaction energies. In this study, we present and test a set of ten ice polymorphs in comparison to experimental data with mass densities ranging from 0.9 to 1.5 g/cm3 and including explicit corrections for zero-point vibrational and thermal effects. London dispersion inclusive density functionals at the generalized gradient approximation (GGA), meta-GGA, and hybrid level as well as alternative low-cost molecular orbital methods are considered. The widely used functional of Perdew, Burke and Ernzerhof (PBE) systematically overbinds and overall provides inconsistent results. All other tested methods yield reasonable to very good accuracy. BLYP-D3atm gives excellent results with mean absolute errors for the lattice energy below 1 kcal/mol (7% relative deviation). The corresponding optimized structures are very accurate with mean absolute relative deviations (MARDs) from the reference unit cell volume below 1%. The impact of Axilrod-Teller-Muto (atm) type three-body dispersion and of non-local Fock exchange is small but on average their inclusion improves the results. While the density functional tight-binding model DFTB3-D3 performs well for low density phases, it does not yield good high density structures. As low-cost alternative for structure related problems, we recommend the recently introduced minimal basis Hartree-Fock method HF-3c with a MARD of about 3%.

    The aim of the present study was to investigate the occurrence of Listeria monocytogenes in ten Sardinian fermented sausage processing plants. A total of 230 samples were collected and 40 L. monocytogenes isolates were obtained and subjected to serotyping and investigated for the presence of ten virulence-associated genes using multiplex PCR assays. The isolates were further subjected to PFGE and investigated for their adhesion abilities in polystyrene microtiter plates. L. monocytogenes was found in 6% of food contact surfaces, in sausages at the end of acidification (3%) and ripening (8%). Serotyping revealed the presence of four serovars: 1/2c (37.5%), 1/2b (27.5%), 4b (22.5%) and 1/2a (12.5%). All virulence-associated genes were detected in 67.5% of the isolates. Isolates from processing environment, semi-processed and finished products showed high pulsotype diversity and the majority of isolates presented weak adhesion capability. The detection of the pathogen in fermented sausages confirms the ability of L. monocytogenes to overcome the hurdles of the manufacturing process.

    Background. Exertional dyspnoea limits level of physical activity in people with Chronic Obstructive Pulmonary Disease (COPD). This randomized, double-blinded, crossover study evaluated the effect of Acu-TENS, application of Transcutaneous Electrical Nerve Stimulation on acupoints, on breathlessness during exercise in people with COPD. Methods. Twenty-one participants, mean% predicted FEV1  50 ± 21%, attended assessment followed by two intervention days, one week apart. On each intervention day, participants performed two endurance shuttle walk tests (ESWT) (Walk 1 and Walk 2). Walk 1 was performed without intervention and Walk 2 was performed with either Acu-TENS or Sham-TENS, in random order, for 45 minutes before and during Walk 2. Duration of each ESWT and dyspnoea score at isotime of Walk 1 and Walk 2 on each intervention day were compared. Between-group differences in ESWT duration and isotime dyspnoea were also compared. Results. At isotime of Walk 1 and Walk 2, Acu-TENS showed significant reduction in dyspnoea of −0.8 point (95% CI −0.2 to −1.4) but not in Sham-TENS [0.1 point (95% CI −0.4 to 0.6)]. Compared to Sham-TENS, Acu-TENS showed significant reduction in dyspnoea of −0.9 point (95% CI −0.2 to −1.6) while no between-group significance was found in ESWT duration. Conclusion. Acu-TENS alleviated dyspnoea during walking in people with COPD but did not increase walking duration. PMID:28303156

    The finiteness of superstring theory at each order in perturbation theory is considered with respect to the ten-dimensional effective action. The quantum consistency of the ten-dimensional superstring effective action is confirmed with an analysis of the perturbative expansion of the quartic sector. It is found to be compatible with the finiteness of reduced four-dimensional theory. Furthermore, implications for the validity of superstring perturbation theory at lower energies is considered.

  15. Stn1-Ten1 is an Rpa2-Rpa3-like complex at telomeres

    In budding yeast, Cdc13, Stn1, and Ten1 form a heterotrimeric complex (CST) that is essential for telomere protection and maintenance. Previous bioinformatics analysis revealed a putative oligonucleotide/oligosaccharide-binding (OB) fold at the N terminus of Stn1 (Stn1N) that shows limited sequence similarity to the OB fold of Rpa2, a subunit of the eukaryotic ssDNA-binding protein complex replication protein A (RPA). Here we present functional and structural analyses of Stn1 and Ten1 from multiple budding and fission yeast. The crystal structure of the Candida tropicalis Stn1N complexed with Ten1 demonstrates an Rpa2N-Rpa3-like complex. In both structures, the OB folds of the two components pack against each other through interactions between two C-terminal helices. The structure of the C-terminal domain of Saccharomyces cerevisiae Stn1 (Stn1C) was found to comprise two related winged helix-turn-helix (WH) motifs, one of which is most similar to the WH motif at the C terminus of Rpa2, again supporting the notion that Stn1 resembles Rpa2. The crystal structure of the fission yeast Schizosaccharomyces pombe Stn1N-Ten1 complex exhibits a virtually identical architecture as the C. tropicalis Stn1N-Ten1. Functional analyses of the Candida albicans Stn1 and Ten1 proteins revealed critical roles for these proteins in suppressing aberrant telomerase and recombination activities at telomeres. Mutations that disrupt the Stn1-Ten1 interaction induce telomere uncapping and abolish the telomere localization of Ten1. Collectively, our structural and functional studies illustrate that, instead of being confined to budding yeast telomeres, the CST complex may represent an evolutionarily conserved RPA-like telomeric complex at the 3' overhangs that works in parallel with or instead of the well-characterized POT1-TPP1/TEBP{alpha}-{beta} complex.

    The Rosetta orbiter carried a dedicated analysis suite for cometary dust. One of the key instruments was MIDAS (Micro-Imaging Dust Analysis System), an atomic force microscope that scanned the surfaces of hundreds of (sub-)micrometre particles in 3D with resolutions down to nanometres. This provided the opportunity to study the morphology of the smallest cometary dust; initial investigation revealed that the particles are agglomerates of smaller subunits [1] with different structural properties [2]. To understand the (surface-) structure of the dust particles and the origin of their smallest building blocks, a number of particles were investigated in detail and the size distribution of their subunits determined [3]. Here we discuss the subunit size distributions ranging from tens of nanometres to a few micrometres. The differences between the subunit size distributions for particles collected pre-perihelion, close to perihelion, and during a huge outburst are examined, as well as the dependence of subunit size on particle size. A case where a particle was fragmented in consecutive scans allows a direct comparison of fragment and subunit size distributions. Finally, the small end of the subunit size distribution is investigated: the smallest determined sizes will be reviewed in the context of other cometary missions, interplanetary dust particles believed to originate from comets, and remote observations. It will be discussed if the smallest subunits can be interpreted as fundamental building blocks of our early Solar System and if their origin was in our protoplanetary disc or the interstellar material.

    Full Text Available This study it has as objective to argue the job of TENS in the spasticity, observing the main parameters, form of application and the mechanism for which TENS it acts in the spasticity. One is about a bibliographical revision based in the literature specialized selected scientific articles through search in the data base of scielo and of bireme, from the sources Medline and Lilacs. The studies found on the job of TENS in the spasticity, had pointed mainly that this chain reduces the spasticity significantly, in lower degrees. The stimulation electrical parameters had disclosed that TENS it (about 100Hz of raised frequency provides one better effect in the reduction of the spasticity. The types of TENS more used had been the conventional and the soon-intense one, however some studies had not presented the used duration of pulse, limit the determination of one better modality of TENS. Few studies had explained the mechanism of performance of the current related one. The ones that had made it, had pointed the release of opioid endogenous (Dynorphins for the central nervous system as main mechanism of performance, however this contrasts with the neurophysiologic bases of the high-frequency stimulation, that demonstrated better resulted in the joined studies. Still it is necessary more studies on the job of this modality of stimulation electrical in the spasticity, since important parameters as duration of pulse, time of application, numbers of attendance and performance mechanism remains without scientific evidence.

    2007-01-01

    Full Text Available Somatosensory input is known to be essential for postural control. The present study examined the effects on postural sway of sensory input delivered via transcutaneous electrical nerve stimulation (TENS applied to the knees during stance. Electrodes from a dual-channel portable TENS unit were adhered to the skin overlying the lateral and medial aspect of both knees of 20 young healthy volunteers (mean age 24.0 years, standard deviation 4.0. Postural sway parameters were obtained during static bipedal stance with an AMTI force platform. Four stimulation conditions were tested with eyes open and with eyes closed: no TENS; TENS applied bilaterally; and TENS applied to either the right or the left knee. Participants underwent two eight-trial blocks, with each trial lasting 30 seconds. The order of conditions was randomized for each participant. Stimulation consisted of a biphasic symmetrical stimulus delivered at the sensory detection level, with a pulse duration of 200μsec and a pulse frequency of 100Hz. The application of TENS induced significant reductions in mean sway velocity and in the medio-lateral dispersion of the center of pressure, with no corresponding effect on the anterior-posterior dispersion. These findings suggest that electrical stimulation delivered at the sensory detection level to the lateral aspects of the knees may be effective in improving balance control, and that this effect may be directionally specific.

    Hypertension is a major risk factor for vascular disease, yet blood pressure (BP) control is unsatisfactory low, partly due to side-effects. Transcutaneous electrical nerve stimulation (TENS) is well tolerated and studies have demonstrated BP reduction. In this study, we compared the BP lowering effect of 2.5 mg felodipin once daily with 30 min of bidaily low-frequency TENS in 32 adult hypertensive subjects (mean office BP 152.7/90.0 mmHg) in a randomized, crossover design. Office BP and 24-h ambulatory BP monitoring (ABPM) were performed at baseline and at the end of each 4-week treatment and washout period. Felodipin reduced office BP by 10/6 mmHg (p TENS reduced office BP by 5/1.5 mmHg (p TENS washout, BP was further reduced and significantly lower than at baseline, but at levels similar to BP after felodipin washout and therefore reasonably caused by factors other than the treatment per se. ABPM revealed a significant systolic reduction of 3 mmHg by felodipin, but no significant changes were noted after TENS. We conclude that our study does not present any solid evidence of BP reduction of TENS.

  1. A Further Study on the Ten-Penny Problem%十文钱问题再探

    2012-01-01

    The ten-penny problem, an old Chinese reasoning illusion problem, was investigated by Li and Zhang for the first time ( 2008), which indicated that only 30% of the subjects succeeded in solving the problem, and resulted in a high error rate in the singleentry bookkeeping representation. However, the fact that most of the resolved-subjects also adopted the single-entry bookkeeping representation strategy was ignored in their studies. Therefore, it may not be appropriate to attribute the high error rate to the single-entry bookkeeping representation strategy. Based on the above analysis, three studies were conducted, and the chi-square test was used for most of the data analysis. In the first study, 198 undergraduate students were asked to solve the ten-penny problem and its heterogeneous issue. They were also required to write down on a booklet their explanations for their solutions. In the second experiment, we changed the presentation of the original problem and the modified problem by weakening the statements for studying whether this change improved their reasoning performance. In the third study, we provided two different cues. One was an external perceptual cue that was embodied by underlining some key state- ments, and the other internal cue required the subjects to apply critical thinking skills to read and resolve the original problem and the modified problem in the instruction. The results of three experiments indicated that ( 1 ) the subjects showed a error rate as high as on the heterogeneous issue of the ten-penny problem; (2) weakening the version of the ten-penny problem significantly improved the correct rate of reasoning; ( 3 ) presenting critical thinking clues also significantly improved the subjects' performance on the ten-penny problem. The results supported the hypotheses that the ten-penny problem was a reasoning illusion problem. The difficulty in solving this problem may be due to ① the surface character of the statement

RESULTADOS: Para G1, o valor de TEN para eliminar o tom de teste foi, em média, próximo ao limiar absoluto para todas as freqüências. Não foi observada ZMC em nenhuma das orelhas testadas do G2. Para as 76 orelhas do G3, 6 não apresentaram indício de ZM. CONCLUSÕES: O TEN é efetivo para indicar ZMC em indivíduos com PANS descendente. Há evidência de diferença na detecção do tom puro na presença de ruído entre indivíduos com PANS em altas freqüências e com PANS plana, pois se observou diferença significativa entre o limiar mascarado e absoluto apenas para PANS descendentes e não para as planas.An audiogram is not sufficient to indicate cochlear dead regions.

RESULTS: In the G1 group the TEN value required to eliminate the test tone was, on average, close to the absolute threshold

  3. Fossil and active fumaroles in the 1912 eruptive deposits, Valley of ten thousand smokes, Alaska

    Fumaroles in the ash-flow sheet emplaced during the 1912 eruption of Novarupta were intensely active throughout the Valley of Ten Thousand Smokes (VTTS) when first studied in 1917. Fumarole temperatures recorded in 1919 were as hot as 645°C. Influx of surface waters into the hot ash-flow sheet provided the fluid flow to sustain the fumaroles but also enhanced cooling so that by the mid-1930's vigorous activity survived only in the vent region. Configuration and distribution of high-temperature fissure fumaroles tens of meters long, that are prevalent in the middle and upper VTTS, were controlled largely by sintering and degree of welding, which in turn controlled fracturing and permeability of the ash-flow tuff. One fracture type developed parallel to the enclosing valley walls during compaction of the ash-flow sheet. Another type extends across the VTTS nearly perpendicular to the flow direction. A third type of randomly oriented fractures developed as cooling contraction cracks during vapor-phase devitrification. In distal parts of the ash-flow sheet where the tuff is nonwelded, prominent fumaroles have irregular funnel-shaped morphologies. Fumarole distribution in the nonwelded part of the ash-flow sheet is concentrated above pre-emplacement river channels. The hottest, longest-lived fumaroles occurred in the upper VTTS near the 1912 vent where the ash-flow sheet is thicker, more indurated, and on average more mafic (richer in dacite and andesite) in contrast to the thinner, nonwelded rhyolitic tuff in the distal part of the sheet. Fumarolic activity was less intense in the distal part of the tuff because of lower emplacement temperatures, more diffuse fumarole conduits in the nonwelded tuff, and the thinness of the ash-flow sheet. Chemical leaching of ash-flow tuff by hot rising fluids took place adjacent to fumarolic conduits in deep parts of the fumaroles. Deposition of incrustation minerals, the components of which were carried upward by fumarolic gases

    Full Text Available Gathering Stories along the Front: A Critical Look at Ten Oorlog [To War]This article reflects critically on the popular television programme Ten Oorlog, thereby examining the field of tension between history and entertainment, between historians and ‘the public’. History can be addressed via various television formats as an historical documentary or a travel programme. An analysis indicates the extent to which Ten Oorlog is inspired by these formats. However, the popular television programme from the outset was not conceived as a classic historical documentary and perhaps can best be described as a historical human interest programme as part of the large-scale commemoration of the First World War. How do history and entertainment relate to one another in this programme? Is there more emphasis on the historical context or on anecdotal stories? This analysis of Ten Oorlog illustrates the tense relation between historians and ‘the public’.Dit artikel werpt een kritische blik op het populaire televisieprogramma Ten Oorlog en gaat daarbij in op het spanningsveld tussen geschiedenis en entertainment, tussen historici en ‘het publiek’. Geschiedenis kan via verschillende formats zoals een historische documentaire of een reisprogramma aan bod komen op televisie. Een analyse van deze formats geeft aan in welke mate Ten Oorlog hierop geïnspireerd is. Het populaire televisieprogramma was echter van begin af aan niet als een klassieke historische documentaire bedoeld en kan misschien het bestomschreven worden als een historisch human interest programma, in het kader van de grootschalige herdenking van de Eerste Wereldoorlog. Hoe verhoudengeschiedenis en entertainment zich daarin? Helt de balans meer over naar historische omkadering of naar anekdotische verhalen? Deze analyse van Ten Oorlog illustreert de gespannen relatie tussen historici en het grote publiek.

    Objective To research the value of virtual touch tissues quantification technique in predicting the occurrence risk of portal hypertension of patients suffering from hepatic fibrosis. Methods Siemens Acuson S2000 ultrasonic diagnostic apparatus was used to conduct common color Doppler ultrasonic examination and liver VTQ test on 61 examinees ( including healthy people and pa⁃tients suffering from chronic liver diseases) , and the relativity among all parameters were compared. Results With the portal hyper⁃tension becoming more and more serious, the patients'liver VTQ value increased with it, portal vein diameter became wide and portal vein peak velocity reduced. There is a certain relativity between them. The test results of the liver VTQ value of the patients suffering from hepatic fibrosis in this region show that when the liver VTQ value is larger than 2.23 m/s, the occurrence risk of portal hyperten⁃sion of patients will significantly rise. Conclusion Virtual touch tissues quantification technique is of a certain value in predicting the occurrence risk of portal hypertension of patients suffering from hepatic fibrosis.%目的:研究声触诊组织量化( VTQ)技术在预测肝纤维化患者门静脉高压发生风险中的价值。方法使用西门子Acuson S2000超声诊断仪,对61例受检者(包括除外肝病史的就诊患者和慢性肝病患者)进行普通彩超检查及肝脏VTQ值测量,对比研究各参数之间的相关性。结果慢性肝病患者随着门静脉高压程度的加重,肝脏VTQ值增大,门静脉内径增宽,门静脉峰值流速减低,各参数之间有一定相关性。根据本地区肝纤维化患者肝脏VTQ检测结果显示,当肝脏VTQ值大于2�23 m/s时,患者发生门静脉高压的风险显著提高。结论声触诊组织量化技术在预测肝纤维化患者门静脉高压发生风险中具有一定价值。

Il est basé sur des entrevues qualitatives auprès de 16 enseignantes et de 16 préposées à l’aide domestique. Pour les deux groupes, les motifs de non-recours incluent la croyance que la CSST existe essentiellement pour les accidents et les retraits préventifs des femmes enceintes, l’image de la CSST comme un organisme qui accorde difficilement des indemnisations ainsi que la difficulté perçue de prouver le lien entre le travail et le problème de santé. Pour les préposées, le manque à gagner entre les prestations et le revenu d’emploi est aussi un facteur tandis que pour les enseignantes l’accès relativement facile à une assurance salaire joue contre le recours à la CSST. De plus, pour bien comprendre les choix des répondantes, il faut tenir compte de leur rapport à leur emploi et à leur santé et de la culture de leur milieu de travail.This article examines the motives behind the decisions of two groups of workers on whether or not to submit claims to the Workers’ Compensation Board (CSST for perceived work-related accidents or illnesses.

    Subfertility and infertility are two major reproductive health problems in human and domestic animals. The contribution of the genotype to these conditions is poorly understood. To examine the genetic basis of male subfertility, we analyzed its relationship to sperm morphology in B10.MOL-TEN1 mice, which shows high-frequencies (about 50%) of morphologically abnormal sperm. Drastic histological changes were also found in the testis of the B10.MOL-TEN1. Segregation analysis showed that the abnormal sperm phenotype in B10.MOL-TEN1 was inherited and was predictably controlled by at least three loci. We also found that male fertility of this strain was normal. These findings indicate a complicated relationship between sperm morphology and male subfertility.

    The aim of this study was to determine whether 3 days of TENS therapy postoperatively after shoulder operations would result in better pain relief and/or reduced analgesic intake when compared to placebo. The study was carried out randomized, double-blind and placebo controlled. Thirty patients were randomized to two groups. The verum group received TENS SM1AKS 80 Hz 6 mA and the placebo group received TENS SM1AKS 80 Hz 0 mA. The pain was assessed pre-operatively using the Hamburg Pain Adjective List. Premedication and Anaesthesia were standardized. TENS was applied to the patients immediately postoperatively for 8 hours and then on the following days 5 times daily for 45 minutes. The effectiveness was evaluated postoperatively using a visual analogue scale (rest, activity), the Hamburg Pain Adjective List and postoperative analgesic consumption. The visual analogue scale at rest and on activity showed no significant difference between the groups. Postoperative analgesic consumption of morphine hydrochloride in the first 24 hours was at time 8 hours postoperative significantly and at all other time points markedly less in the verum group compared to the placebo group. The sensory secondary scale score of the "Hamburg Pain Adjective List" was significantly lower postoperatively compared to preoperatively in the verum group. We were able to show in this study that TENS applied postoperatively after shoulder surgery clearly reduced analgesic consumption in the first 72 hours. Furthermore there was a significant difference in the pain scores using the "Hamburg Pain Adjective List" in favour of the verum group. TENS applied postoperatively is a effective, simple modality with few side-effects.

    Predation by raccoons, Procyon lotor marinus (L.), is the primary cause of sea turtle nest loss in the Ten Thousand Islands archipelago. Four islands within Ten Thousand Islands National Wildlife Refuge were surveyed for sea turtle nesting activity from 1991-95. Raccoons depredated 76-100% of nests on Panther Key from 1991-94, until 14 raccoons were removed in 1995 resulting in 0% depredation and 2 more were removed in 1996 resulting in 0% depredation. Raccoon removal may be an effective management option for increasing sea turtle nest survival on barrier islands.

    Full Text Available Background: Diabetic Neuropathy is a condition that damages nerve in the body. High blood sugar levels affect the way nerves use glucose leading to an accumulation of sugar SORBITOL as depletion of substance called MYOINOSITOL with in nerves, contributing to nerve damage. Historically De calvi first showed the relationship between diabetes and peripheral nerve damage. Diabetes Mellitus is predicted to afflict 220 Million people worldwide by the year 2010, and approximately 30-60% of patients with Diabetes develop long-term of peripheral neuropathy and upto 10 to 20% of these patients experience pain. Pirart8, showed the incidence of Diabetic Neuropathy to be 7.5% at the time of diagnosis with a 1.7% annual increase. [International Diabetes Federation]. Method: Thirty subjects were divided equally 2 groups each containing subjects Group A were given TENS, (mean age 53.2, while group B was given placebo TENS mean age of 50.8 and Visual Analog Scale [VAS] scores > 5 were calculated and data collected for all the subjects prior to the treatment and after the treatment intervention. Wilcoxon method was used for analysis. Results: The Experimental group (N=15 used TENS, the mean of Pre-treatment VAS Score is 8.46 and Post-treatment VAS Score is 2.6 and statistically when observed by using the Wilcoxon signed ranks test the obtained T Value =7 and it shows a significant. Discussion: There are 2 potential mechanisms by which High – Frequency TENS can relieve the pain of diabetic neuropathy. It is possible that TENS alleviates pain by directly blocking abnormal spontaneous activity in small diameter pain mediating peripheral nerves. This mechanism requires electrical stimulation to be applied directly to spontaneously active nerve. In addition TENS can relieve the pain of diabetic neuropathy by altering nociceptive transmission in the dorsal horn of spinal cord. The second mechanism requires that stimulation be delivered to spinal cord segments that

    Full Text Available Abstract Background Engineered nanomaterials display unique properties that may have impact on human health, and thus require a reliable evaluation of their potential toxicity. Here, we performed a standardized in vitro screening of 23 engineered nanomaterials. We thoroughly characterized the physicochemical properties of the nanomaterials and adapted three classical in vitro toxicity assays to eliminate nanomaterial interference. Nanomaterial toxicity was assessed in ten representative cell lines. Results Six nanomaterials induced oxidative cell stress while only a single nanomaterial reduced cellular metabolic activity and none of the particles affected cell viability. Results from heterogeneous and chemically identical particles suggested that surface chemistry, surface coating and chemical composition are likely determinants of nanomaterial toxicity. Individual cell lines differed significantly in their response, dependent on the particle type and the toxicity endpoint measured. Conclusion In vitro toxicity of the analyzed engineered nanomaterials cannot be attributed to a defined physicochemical property. Therefore, the accurate identification of nanomaterial cytotoxicity requires a matrix based on a set of sensitive cell lines and in vitro assays measuring different cytotoxicity endpoints.

Study Design: In 23 patients 22 inlays/onlays (Group A) were luted using a dual-cured resin composite cement and 26 inlays/onlays (Group B) were luted using a light cured resin composite for a total of 48 Class I and Class II indirect composite resin inlays and onlays. The restorations were evaluated at 2 time points: 1) one week after placement (baseline evaluation) and 2) ten years after placement using the modified USPHS criteria. The Mann-Whitney and the Wilcoxon tests were used to examine the difference between the results of the baseline and 10 years evaluation for each criteria. Results: Numerical but not statistically significant differences were noted on any of the recorded clinical parameters (p>0.05) between the inlay/onlays of Group A and Group B. 91% and 94 % of Group A and B respectively were rated as clinically acceptable in all the evaluated criteria ten years after clinical function. Conclusions: Within the limits of the study the results showed after ten years of function a comparable clinical performance of indirect composite resin inlays/onlays placed with a light cure or dual cure luting procedures. Key words:Light curing composite, dual curing composite, indirect composite restoration, inlays/onlays, clinical trial. PMID:25810842

    The study set out to investigate the therapeutic effect of Transcutaneous Electrical Nerve Stimulation (TENS) in the alleviation of pain and post-IMF trismus, in patients undergoing jaw exercises to hasten mouth opening after being treated for fractures of the mandible. Two groups of patients, with 10 patients in each group, were used for the study. The groups were the experimental and the control groups. They were all treated for mandibular fractures, and had their jaws immobilized for 6 weeks, immediately after which they were started on jaw exercises. The Inter-incisal distances and number of acceptable wooden spatulae that the jaws could accommodate were noted and recorded. The experimental group was then placed on the TENS therapy for 20 minutes, after which the new inter-incisal distances and the number of acceptable wooden spatulae were recorded. The control group had no TENS therapy; the patients only waited for 20 minutes without any stimulation, before the new inter-incisal distances and the number of acceptable wooden spatulae were measured and recorded. It was observed that the inter-incisal distance and the number of acceptable wooden spatulae significantly increased in patients in the experimental group compared to the control group. It was concluded that TENS could be useful in relieving the pain associated with forced mouth-opening exercises aimed at overcoming trismus caused by muscle spasm, which is associated with prolonged immobilization of the jaws for the treatment of facial fractures.

    2012-07-01

    We report the ten-year survival of a cemented total knee replacement (TKR) in patients aged 55 years at the time of surgery, and compare the functional outcome with that of patients aged > 55 years. The data were collected prospectively and analysed using Kaplan-Meier survival statistics, with revision for any reason, or death, as the endpoint. A total of 203 patients aged 55 years were identified. Four had moved out of the area and were excluded, leaving a total of 221 TKRs in 199 patients for analysis (101 men and 98 women, mean age 50.6 years (28 to 55)); 171 patients had osteoarthritis and 28 had inflammatory arthritis. Four patients required revision and four died. The ten-year survival using revision as the endpoint was 98.2% (95% confidence interval 94.6 to 99.4). Based on the Oxford knee scores at five and ten years, the rate of dissatisfaction was 18% and 21%, respectively. This was no worse in the patients aged 55 years than in patients aged > 55 years. These results demonstrate that the cemented PFC Sigma knee has an excellent survival rate in patients aged 55 ten years post-operatively, with clinical outcomes similar to those of an older group. We conclude that TKR should not be withheld from patients on the basis of age.

    2009-02-01

    The genotyping of 313 random individuals belonging to ten different population groups from three different states of India was performed for polymorphic pentanucleotide repeat present in the 5'-flanking region of nitric oxide synthase gene (NOS2A) to study the effect of geographical and linguistic affiliations on the genetic affinities among these groups. Likelihood ratio tests showed that all the ten populations for this locus were in Hardy Weinberg equilibrium. Eleven different alleles ranging from 7 repeat to 17 repeats and 46 different genotypes were observed. The observed and the expected heterozygosity ranged from 0.72-0.94 and 0.84-0.89, respectively. The discriminating power of this locus is > or = 0.86 and the polymorphism information content of this locus in ten population groups ranged from 0.80 to 0.85. High PIC, PD and PE value of this STR showed this marker to be informative and can be used for DNA typing and population studies. The eight populations from Kerala showed a lower GST value of 0.016 compared to the GST of ten populations (G(ST) = 0.019), thereby showing that the populations from the same state showed higher genetic proximity probably due to linguistic and geographical proximity between them.

  1. Ten-a affects the fusion of central complex primordia in Drosophila.

    Directory of Open Access Journals (Sweden)

    Xuebo Cheng

    Full Text Available The central complex of Drosophila melanogaster plays important functions in various behaviors, such as visual and olfactory memory, visual orientation, sleep, and movement control. However little is known about the genes regulating the development of the central complex. Here we report that a mutant gene affecting central complex morphology, cbd (central brain defect, was mapped to ten-a, a type II trans-membrane protein coding gene. Down-regulation of ten-a in pan-neural cells contributed to abnormal morphology of central complex. Over-expression of ten-a by C767-Gal4 was able to partially restore the abnormal central complex morphology in the cbd mutant. Tracking the development of FB primordia revealed that C767-Gal4 labeled interhemispheric junction that separated fan-shaped body precursors at larval stage withdrew to allow the fusion of the precursors. While the C767-Gal4 labeled structure did not withdraw properly and detached from FB primordia, the two fan-shaped body precursors failed to fuse in the cbd mutant. We propose that the withdrawal of C767-Gal4 labeled structure is related to the formation of the fan-shaped body. Our result revealed the function of ten-a in central brain development, and possible cellular mechanism underlying Drosophila fan-shaped body formation.

    Despite national recognition for their breastfeeding-friendly practices, many New Hampshire hospitals are still not achieving the Ten Steps to Successful Breastfeeding. To increase achievement of the Ten Steps in New Hampshire's birthing hospitals, facilitate Baby-Friendly Hospital Initiative (BFHI) designation for interested hospitals, and improve rates of in-hospital any and exclusive breastfeeding. After a 2010 needs assessment, we conducted 2 statewide workshops targeting 6 of the Ten Steps found to be most deficient among New Hampshire birthing hospitals. Eighteen of 20 hospitals attended at least 1 workshop, and 6 participated in an intensive collaborative. In 2013, we analyzed interval Ten Step achievement and in-hospital breastfeeding trends. Staff education showed the greatest improvement, increasing step 2 achievement from 1 to 6 hospitals (P=.05). Although the number of hospitals implementing step 6 (breast milk only) and step 9 (no artificial nipples) increased, differences were not statistically significant. Intensive collaborative hospitals achieved an average of 1.5 new steps, whereas non-Baby Friendly hospitals lost 0.7 steps (P=.05). In-hospital breastfeeding rates increased in intensive collaborative hospitals and were significantly higher than those in non-Baby Friendly hospitals by the end of the study (any breastfeeding, 89% vs 73%, P=.03; exclusive breastfeeding, 84% vs 61%, Pbreastfeeding for hospitals participating in an intensive collaborative. Active work in Ten Step implementation, including staff education, appears to be more effective in increasing in-hospital breastfeeding than does BFHI designation alone.

    Transcutaneous electrical nerve stimulation (TENS) is a popular form of electrostimulation. Despite an extensive research base, there remains no consensus regarding the parameter selection required to achieve maximal hypoalgesic effects. The aim of this double blind, sham-controlled study was to investigate the relative hypoalgesic effects of different TENS parameters (frequency, intensity and stimulation site) upon experimentally induced mechanical pain. Two hundred and forty participants were recruited in order to provide statistical analysis with 80% power at alpha = 0.05. Subjects were randomised to one of the six TENS groups, a control, and a sham TENS group (n = 30, 15 males, 15 females, per group). TENS groups differed in their combinations of stimulation; frequency (4 or 110 Hz), intensity ('to tolerance' or 'strong but comfortable') and stimulation site (segmental--over the distribution of the radial nerve or, extrasegmental--over acupuncture point 'gall bladder 34', or a combination of both segmental and extrasegmental). Pulse duration was fixed at 200 micros. Stimulation was delivered for 30 min and subjects were then monitored for a further 30 min. Mechanical pain threshold (MPT) was measured using a pressure algometer and taken from the first dorsal interosseous muscle of the dominant hand, ipsilateral to the stimulation site. MPT measures were taken, at baseline, and at 10-min intervals for 60 min. Difference scores were analysed using repeated measures and one-way ANOVA and relevant post hoc tests. Low frequency, high intensity, extrasegmental stimulation produced a rapid onset hypoalgesic effect, which increased during the stimulation period (P < 0.0005 control and sham) and was sustained for 30 min post-stimulation (P < 0.0005(control), P = 0.024(sham)). Whilst high frequency, 'strong but comfortable' intensity, segmental stimulation produced comparable hypoalgesic levels during stimulation, this effect was not sustained post

    Full Text Available Background: Cervical radiculopathy is a dysfunction of nerve root of the cervical spine where C6& C7 nerve roots are the most commonly affected. It encompasses important symptoms other than pain, such as paresthesia, numbness and muscle weakness in dermatomal or myotomal distribution of an affected nerve root. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy, including mechanical cervical traction, manipulation, therapeutic exercises and TENS. Studies to find out the effectiveness of TENS versus Intermittent Cervical Traction among patients with Cervical Radiculopathy are sparse. Hence the present study was undertaken to find out and compare effectiveness of TENS versus Intermittent Cervical Traction a newer technique towards betterment in treatment of cervical radiculopathy patients. Methodology: 30 patients from Baroda association for the blind (Lions club of Baroda, Subhanpura & Sushrut Physiotherapy Clinic, Akota were chosen based on the inclusion and exclusion criteria. Group A comprised of 15 people with cervical radiculopathy were given TENS with Isometric neck exercises and active neck movements. Group B comprised of 15 people with cervical radiculopathy were given Intermittent Cervical Traction with Isometric neck exercise and active neck movements. VAS Scale & Neck Disability Index (NDI were used as outcome measures pre & post treatment. Results: The pre test evaluation showed that, there is no significant difference (P> 0.05 between the two groups for all the variables measured. The post-test evaluation of both groups showed a very high significance (P< 0.05 within the group for all the outcome measurements. A post-test comparison of measured variables, between the groups showed that the Group A demonstrated a statistically significant (P< 0.05 reduction in pain and Neck Disability Index. Conclusion: From the above study concluded that TENS was more effective

    Spasticity management is pivotal for achieving functional recovery of stroke patients. The purpose of this study was to investigate the effects of a single trial of transcutaneous electrical nerve stimulation (TENS) on spasticity and balance in chronic stroke patients. Forty-two chronic stroke patients were randomly allocated into the TENS (n = 22) or the placebo-TENS (n = 20) group. TENS stimulation was applied to the gastrocnemius for 60 min at 100 Hz, 200 µs with 2 to 3 times the sensory threshold (the minimal threshold in detecting electrical stimulation for subjects) after received physical therapy for 30 min. In the placebo-TENS group, electrodes were placed but no electrical stimulation was administered. For measuring spasticity, the resistance encountered during passive muscle stretching of ankle joint was assessed using the Modified Ashworth Scale, and the Hand held dynamometer was used to assess the resistive force caused by spasticity. Balance ability was measured using a force platform that measures postural sway generated by postural imbalance. The TENS group showed a significantly greater reduction in spasticity of the gastrocnemius, compared to the placebo-TENS group (p TENS resulted in greater balance ability improvements, especially during the eyes closed condition (p TENS provides an immediately effective means of reducing spasticity and of improving balance in chronic stroke patients. The present data may be useful to establish the standard parameters for TENS application in the clinical setting of stroke.

      Objective To explore the effect of autologous skin transplantation with skin flap taken on reverse side using drum type dermatome in treating extensive skin avulsion of upper limbs. Methods Retrospective analysis was con-ducted on 9 patients with extensive skin avulsion of the upper limbs admitted to our hospital from April 2006 to June 2010. All the patients underwent urgent debridement. The avulsed skin soft tissue deprived of blood supply was removed, shaved into medium split thickness skin flaps using drum type dermatome, and replanted them on the wound. Layering dressing was applied with Amikacin Saline gauzes as the inner layer, aseptic bandages in the middle and cotton pads as the outer layer. The injured extremities were suspended post operation to avoid local compression. The outer layer of dressing was changed 3 days post operation and the suture was removed 12 days post operation. Results More than 95% of the transplant survived in the 9 cases. Sporadical small wounds healed with the dressing change of MEBO and no second operation was required. Function of the injured extremities restored sufficiently with exercise. Conclusion Autologous skin transplantation with skin flap taken on reverse side using drum type dermatome is a relatively ideal surgical approach to treating extensive skin a-vulsion of upper limbs. Adequate debridement and hemostasis with appropriate dressing and overhanging to avoid compres-sion can increase the survival rate of the transplant.%  目的探讨上肢大面积皮肤撕脱伤反鼓取皮植皮术的临床效果。方法回顾性分析2006年4月至2010年6月收治的9例上肢大面积皮肤撕脱伤患者病历资料,急诊行清创术,将撕脱失去血供的皮肤软组织取下,用鼓式取皮机修成中厚皮片后,原位回植于创面,术区分层包扎,内层用阿米卡星盐水纱布、消毒绷带包扎,外层用棉垫包扎,术后悬吊,避免局部受压,术后3 d 更换外层敷料,12 d

    Full Text Available Temporomandibular disorders (TMD are characterized by several signs and symptoms, such as pain and changes in the electrical activity of masticatory muscles. Considering that transcutaneous electrical nerve stimulation (TENS is a resource indicated to promote analgesia, the objective of this study was to evaluate the effect of TENS on pain and electromyographic (EMG activity of the jaw elevator muscles in TMD patients. This study evaluated 35 female volunteers: 19 TMD patients (mean age = 23.04 ± 3.5 and 16 normal subjects (mean age = 23.3 ± 3.0. Transcutaneous electrical nerve stimulation (conventional mode, 150 Hz was applied once to each group for 45 minutes. Surface electromyography (gain of 100 times and 1 kHz sampling frequency and the visual analogue scale (VAS were applied before and immediately after TENS application. Both VAS data and root mean square (RMS values were analyzed using Student's t-test. The TMD group, compared to the control group, showed higher EMG activity of the jaw elevator muscles at rest. No difference was observed between the groups regarding maximum voluntary clenching (MVC. In TMD patients, TENS reduced both pain and EMG activity of the anterior portion of the temporal muscle, increasing the activity of the masseter muscles during MVC. It is possible to conclude that a single TENS application is effective in pain reduction. However, it does not act homogeneously on the features of the electric activity of the muscles evaluated.A desordem temporomandibular (DTM é caracterizada por diversos sinais e sintomas, como dor e alteração do sinal eletromiográfico dos músculos da mastigação.

    Full Text Available Este artigo examina a interação da ética, da antropologia social e da epistemologia na saúde pública. Na primeira seção do artigo, introduzimos ao amplo espectro de abordagens existentes que consideram a saúde pública como um campo político, como uma ciência e como um projeto antropológico global que levanta inúmeras questões éticas. Na segunda seção, propomos uma apresentação mais detalhada das principais questões levantadas pela saúde pública através de uma rede de quatro tensões dialéticas fundamentais. A primeira tensão concerne principalmente às dubiedades das definições de saúde e às finalidades propostas para esse campo. A segunda tensão concerne à legitimidade dos meios utilizados para chegar aos objetivos da saúde pública. A terceira tensão diz respeito ao regime de evidência e ao referencial das abordagens empregadas na saúde pública. A quarta tensão se origina nas relações de poder construídas no interior dessas práticas da saúde pública. Sugerimos que essas quatro tensões, nas quais a polarização apresenta uma variedade de formatos, relacionam-se entre si. Isso conduz à conclusão de que na saúde pública, as considerações éticas, antropológicas e epistemológicas precisam andar juntas. Para entender criticamente as questões da saúde pública, precisamos, portanto, levar em conta as íntimas interações entre as ciências, os valores e as práticas.

    It is well-known, even at the most elementary level of scientific knowledge, that free surfaces have properties which make them differ from the underlying bulk material. In the case of liquids, it is common knowledge - even among laymen - that the liquid surface acts as though it were a distinct skin-like material. At a slightly more advanced level, it is known that the liquid surface will seek to minimize its total surface energy by minimizing its surface area; thereby affecting its local vapor-pressure and adsorption behavior. In the case of solids too, it has long been known that different

    With the increasing clinical use of 3D surface scanners, there is a need for accurate and reliable algorithms that can produce anatomically plausible surfaces. In this paper, a combined method for surface alignment and reconstruction is proposed. It is based on an implicit surface representation...... combined with a Markov Random Field regularisation method. Conceptually, the method maintains an implicit ideal description of the sought surface. This implicit surface is iteratively updated by realigning the input point sets and Markov Random Field regularisation. The regularisation is based on a prior...... energy that has earlier proved to be particularly well suited for human surface scans. The method has been tested on full cranial scans of ten test subjects and on several scans of the outer human ear....

    The objective of this study was to investigate the effects and mechanism of Transcutaneous Electrical Nerve Stimulation (TENS) on the diabetic cytopathy (DCP) in the diabetic bladder. A total of 45 rats were randomly divided into diabetes mellitus (DM)/TENS group (n=15), DM group (n=15) and control group (n=15). The rats in the DM/TENS and TENS groups were electronically stimulated (stimulating parameters: intensity-31 V, frequency-31 Hz, and duration of stimulation of 15 min) for three weeks. Bladder histology, urodynamics and contractile responses to field stimulation and carbachol were determined. The expression of calcitonin gene-related peptide (CGRP) was analyzed by RT-PCR and Western blotting. The results showed that contractile responses of the DM rats were ameliorated after 3 weeks of TENS. Furthermore, TENS significantly increased bladder wet weight, volume threshold for micturition and reduced PVR, V% and cAMP content of the bladder. The mRNA and protein levels of CGRP in dorsal root ganglion (DRG) in the DM/TENS group were higher than those in the DM group. TENS also significantly up-regulated the cAMP content in the bladder body and base compared with diabetic rats. We conclude that TENS can significantly improve the urine contractility and ameliorate the feeling of bladder fullness in DM rats possibly via up-regulation of cAMP and CGRP in DRG.

    The past ten years have seen several interesting demonstrations of 1-3 piezocomposite when used as the active component in sonar sensors. Initially considered receive only by most in the field, piezocomposite has evolved into a proven broadband transducer material with both receive and transmit capability. From large aperture single element calibration transducers, to parametric mode projectors, the material has surprised many experts with its power handling capability. Its polymer constituent provides an amazing degree of versatility by allowing the thermoforming and shaping of transducer substrates for packaging into todays undersea vehicles. This talk will review the last ten years of piezocomposite transducer and array development focusing on both the materials transmit behavior and fabrication benefits for future sonar applications.

    Full Text Available Abstract Primary lymphoma is an uncommon malignancy of the thyroid, comprising of 0.6 to 5 per cent of thyroid cancers in most series. Primary thyroid lymphomas (PTL occur most commonly in elderly women and are commonly of B- cell origin. These frequently present in clinical stage IE and IIE. We report here ten cases of PTL diagnosed over a period of about 7 years in our institute. Out of these ten cases, nine were diagnosed on fine needle aspiration cytology (FNAC and one case was misdiagnosed as lymphocytic thyroiditis. This case was diagnosed as Non- Hodgkin's lymphoma on surgical specimen. Five patients are disease free and doing well, while two died of disease and the other two were lost to follow-up. One patient is currently on chemotherapy. The salient clinical, biochemical, radiological features, FNA findings along with diagnostic difficulties are discussed.

Anticoagulants and corticosteroids could be effective for dealing with APS. It was critical to treat catastrophic APS with anticoagulants or plasmapheresis as early as possible. Conclusions: APS shows variable manifestations for good prognosis, but catastrophic APS has fatal risk. The main treatment for APS is the use of anticoagulants and immunosuppressives.

    Based on the daily price data of spot prices of West Texas Intermediate (WTI) crude oil and ten CSI300 sector indices in China, we apply multifractal detrended cross-correlation analysis (MF-DCCA) method to investigate the cross-correlations between crude oil and Chinese sector stock markets. We find that the strength of multifractality between WTI crude oil and energy sector stock market is the highest, followed by the strength of multifractality between WTI crude oil and financial sector market, which reflects a close connection between energy and financial market. Then we do vector autoregression (VAR) analysis to capture the interdependencies among the multiple time series. By comparing the strength of multifractality for original data and residual errors of VAR model, we get a conclusion that vector auto-regression (VAR) model could not be used to describe the dynamics of the cross-correlations between WTI crude oil and the ten sector stock markets.

    2003-09-01

    Two high-pitched and long sustained notes, F5 and A5, were selected from an aria found in ten commercial recordings of G Verdi's opera Aida by ten different sopranos. Both notes were sung without any instrumental accompaniment and with a crescendo. These audio examples were analyzed with regard to fundamental frequency, vibrato rate, vibrato extent, intonation and sound level, and the relationship among these parameters. The results reveal that vibrato rate differed significantly between the tones in most of the singers and confirm Prame's observations that vibrato rate tends to increase exponentially toward the end of tones. Moreover, both vibrato extent and mean F0 often varied systematically with sound level. The regularity of the vibrato tended to be greater at F5 than at A5.

    In this report ten cases of acute radiation syndrome are described resulting from two accidents occurring at the Los Alamos Scientific Laboratory of unique nature involving fissionable material. These cases are described in considerable detail. The report comprises ten sections. This volume, part II of the report, is comprised of sections entitled: (1) the Biological Basis for the Clinical Response seen in the Acute radiation Syndrome, (2) Clinical Signs and Symptoms, (3) Discussion of Hematological Findings, (4) Chemistry of the Blood and Urine, (5) Discussion of Pathological Findings, and (6) Reconsiderations of the Calculated Radiation Doses in Terms of the Observed Biological Response of the Patients. This report was prepared primarily for the clinician who is interested in radiation injuries and therefore emphasis has been placed on the correlation of clinical and pathological changes with the type of cytogenetic change known to be produced by ionizing radiation.

    Identifying patients at risk of poor outcome at an early stage of illness can aid in treatment planning. This study sought to create a best-fit statistical model of known baseline and early-course risk factors to predict time in psychosis during a ten-year follow-up period after a first psychotic episode. Between 1997 and 2000, 301 patients with DSM-IV nonorganic, nonaffective first-episode psychosis were recruited consecutively from catchment area-based sectors in Norway and Denmark. Specialized mental health personnel evaluated patients at baseline, three months, and one, two, five, and ten years (N=186 at ten years). Time in psychosis was defined as time with scores ≥4 on any of the Positive and Negative Syndrome Scale items P1, P3, P5, P6, and G9. Evaluations were retrospective, based on clinical interviews and all available clinical information. During the first two years, patients were also evaluated by their clinicians at least biweekly. Baseline and early-course predictors of long-term course were identified with linear mixed-model analyses. Four variables provided significant, additive predictions of longer time in psychosis during the ten-year follow-up: deterioration in premorbid social functioning, duration of untreated psychosis (DUP) of ≥26 weeks, core schizophrenia spectrum disorder, and no remission within three months. First-episode psychosis patients should be followed carefully after the start of treatment. If symptoms do not remit within three months with adequate treatment, there is a considerable risk of a poor long-term outcome, particularly for patients with a deterioration in premorbid social functioning, a DUP of at least half a year, and a diagnosis within the core schizophrenia spectrum.

    Chronic urticaria can be the initial clinical presentation of a number of different diseases. The objective of the present study was to report the associated diseases during a ten-year clinical-laboratory follow-up in patients with an initial diagnosis of chronic spontaneous urticaria (CSU) of unknown cause. A prospective, longitudinal cohort study with a ten-year clinical-laboratory follow-up was conducted. Patients with a history of urticarial plaques of over six weeks presenting as the only clinical symptom were selected. Individuals with other clinical conditions, urticaria of known causes or chronic physical urticaria were excluded. The following tests were initially performed: haemogram, urine type I, stool parasite exam and sedimentation rate. The following exams were ordered during follow-up: PPD; urine culture; serology tests; antithyroid and antinuclear antibodies, rheumatoid factor, lupus anticoagulant; thyroid hormones; serum immunoglobulin; paranasal sinus and thorax radiographs; testing for BK and Helicobacter pylori; and prick tests. Infections were diagnosed in 29% of patients (syphilis, parasitosis, H. pylori, urinary infection, tuberculosis, hepatitis B and C); autoimmune diseases in 21% (thyroiditis, rheumatoid arthritis and antiphospholipid antibody syndrome); primary immunodeficiencies in 4% (IgA and IgG2 deficiencies); and chronic myeloid leukaemia in 1%. At ten-years of follow-up, the urticaria diagnosis was CSU of unknown cause in 45% of the cases. This ten-year clinical-laboratory follow-up of 100 individuals with chronic urticaria as the initial diagnosis revealed the presence of associated diseases in over half of the cases. The most prevalent diseases were infections and autoimmune diseases besides primary immunodeficiencies and blood diseases. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U.

    2012-12-01

    The Ten Steps to Successful Breastfeeding is a proven approach to support breastfeeding in maternity settings; however, scant literature exists on the relative impact and interpretation of each step on breastfeeding. We assessed the Ten Steps and their relationship with in-hospital breastfeeding rates at facilities serving low-wealth populations and explored the outcomes to identify step-specific actions. We present descriptive and nonparametric comparisons and qualitative findings to examine the relationship between the Ten Steps and breastfeeding rates from each hospital using baseline data collection. Some steps (1--policy, 2--training, 4--skin-to-skin, 6--no supplements, and 9--no artificial nipples, followed by 3--prenatal counseling, 7--rooming-in) reflected differences in relative baseline breastfeeding rates between settings. Key informant interviews revealed misunderstanding of some steps. Self-appraisal may be less valid when not all elements of the criteria for evaluating Step implementation may be fully understood. Limited exposure and understanding may lead to self-appraisal errors, resulting in scores that are not reflective of actual practices. Nonetheless, the indication that breastfeeding rates may be better mirrored by a defined subset of steps may provide some constructive insight toward prioritizing implementation activities and simplifying assessment. These issues will be further explored in the next phase of this study.

    Full Text Available Pinus brutia Ten., Red pine, known to be tough drought resistant pine specie, could effectively be used for afforestation of disturbed areas. It is of great interest for the afforestation in arid zones. Appropriate seed sources for the specific areas guarantees reforestation success. Away from its native areas Pinus brutia Ten. is planted for its ornamental value and timber production purposes. Selection of drought resistant provenances can very well increase the survival success. In this study, the effects of water potential on germination were studied in fourteen provenances of Pinus brutia Ten. from Turkey. Water potentials between 0 and -8 bars were obtained using polyethylene glycol 6000 (PEG-6000 solutions. Seeds were kept for 35 day at 20 ± 0.5°C. A decrease in water potential produced a marked reduction in germination percentage and germination value. As a result, significant variations between the provenances were found. It was determined that, under a -8 bar water stress, Isparta-Bucak and Mersin-Silifke, respectively corresponding to 58% and 57% of the control group, were the least water stress affected provenances.

    Full Text Available Background: In the area of exporting, in developing countries, including Iran, the concept of export readiness is unknown to many decision makers and field of activity of Iranian pharmaceutical companies have been limited to the domestic market. Therefore, the main objective of this study is to compare the export performance of ten Iranian pharmaceutical companies with their export readiness. Methods: In order to do this, the top ten of Iranian pharmaceutical companies were selected as the sample. The companies' export readiness was measured, and compared with their export volume as well as their export growth (as two factors for determining the export performance in five years, to practically check the model and find the strengths and weaknesses of these Iranian pharmaceutical companies in the export factors. Results: Base on the results of the study, the export readiness of these companies does not have significant correlation with companies' export volume in the current circumstances, but it can predict the export growth in the firm's export rate with 95% certainty. Conclusion: The most important thing is that according to the data collected in our study, most of these ten Iranian pharmaceutical companies are not ready to attend in exporting and international markets and only two companies were ready to export. It seems that making improvement in some variables like obtaining international standards, marketing and exporting education, having a transparent and documented plan and having the responsible person for export could increase export readiness of pharmaceutical companies.

    Full Text Available A retrospective analysis of 24 patients with established osteoporosis and with ten or more years of menopause treated with conjugated estrogen, progesterone and calcium followed for one year has been performed. Treated women received 0.625 mg/day of conjugated estrogen from day 1 to 25, 5 mg/day of medroxiprogesterone from day 13 to 25, of each cycle, plus calcium (500 - 1000 mg/day, during one year (12 cycles. As control group was used 18 age-matched that received only calcium (500 a 1000 mg/day. All patients had at least two dual-photon spine and proximal femur (neck, Ward's triangle and trocanter densities measurements performed 12 months apart. Estrogen treatment was associated with increased bone mineral density at spine and trocanter. Control group did not present any statistically change after one year in any site studied. We concluded that women with ten or more years of menopause and established osteoporosis treated with replacement hormonal therapy and calcium results in improvement of bone mineral density. These data support that women with ten or more years of menopause respond to estrogen replacement therapy with absolute increments in bone density similar to those seen in younger women, in the early menopause.

    Motivation has long been associated with sports engagement. However, to date no research has been performed to understand the domain of motivation among ten-pin bowlers. The purpose of this study was to investigate different types of motivation (i.e., intrinsic vs. extrinsic) based on self-determination theory from the perspective of gender and the bowler type (competitive vs. casual). A total of 240 bowlers (104 male, 136 female; 152 competitive, 88 casual) with a mean age of 16.61 ± 0.78 years were recruited in Kuala Lumpur. The Sport Motivation Scale, a 28-item self-report questionnaire measuring seven subscales (i.e., intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, extrinsic motivation to identify regulation, extrinsic motivation for introjection regulation, extrinsic motivation to external regulation, and amotivation) was administered. Results showed significant differences (t=10.43, df=239, p=0.01) between total scores of intrinsic and extrinsic motivation among ten-pin bowlers. There were significant gender differences with respect to intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, and extrinsic motivation to identify regulation. However, no significant bowler type differences were found for either the intrinsic (t=-1.15, df=238, p=0.25) or extrinsic (t=-0.51, df=238, p=0.61) motivation dimensions. In conclusion, our study demonstrated substantial intrinsic motivation for gender effects, but no bowler type effects among adolescent ten-pin bowlers.

    Meng, Jie; Sun, Yuxiu; Li, Yan

    2014-07-01

    Metal-organic frameworks (MOFs) are concerned mainly due to the unusual properties for diverse analytical applications, such as high surface area, good thermal stability, inpore functionally and outer-surface modification. Two metal-organic complexes were prepared by two methods of hydrothermal synthesis and room temperature synthesis, separately. The compositions, structures, thermal stability and adsorption properties of the two complexes were characterized by X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and Brunauer-Emmett-Teller (BET) method, which indicated that the two complexes have not only good thermal stability but also good adsorption for polycyclic aromatic hydrocarbons (PAHs). PAHs enter into environment leading to pollution by industrial and agricultural production and life, rooting in the incomplete combustion or pyrolysis of organism. PAHs are strongly carcinogenic and mutagenic. Some PAHs are considered as endocrine disruptors, and maybe have biological effects on human health. Regulations have thus been formulated for monitoring and controlling PAHs by the United States Environmental Protection Agency (U.S. EPA) and other government agencies. Adsorption kinetic of PAHs on the two complexes could be well described by the pseudo-second order kinetic model, and the adsorption behaviors of the two complexes on PAHs are in accord with Langmuir model. In addition, the adsorption capacities increase with the increasing adsorbent dosage. It is proved by the FT-IR data that pi-pi interactions between the PAHs and the framework terephthalic acid molecules. Ten PAHs were adsorbed well on the two complexes which have good adsorptive selectivity. By further optimizing of the two complex materials, it is promising to use them as chromatographic stationary phases.

    Full Text Available Medical audit in general consists of seven steps like choosing topic, setting criterion and standard, collecting first data, comparing data with standard, introducing change, collecting second data and reflecting. Its three basic premise are improvement of patient care by using existing knowledge, team work with ongoing educational process and change management and promotion of blame-free culture maintaining confidentiality. Audit mostly relates to a particular practice and is therefore not generalisable. An audit of residents' late evening routine notes of organophosphate poisoning patients is reported here, as the change introduced appears relevant to the situation of developing countries. Organophosphate poisoning patients should be managed in intensive care unit with close monitoring, as inadvertent stoppage or slowing of atropine infusion may occur, particularly at night, leading to reappearance of poisoning manifestations, which may cause respiratory failure and death. If they are managed in wards, residents-on-duty can check the clinical and intravenous drip status in the late evening and communicate with nurses and relatives to be particularly vigilant. In the audit done, such regular ten pm notes of organophosphate poisoning about the clinical and drip status and communication by residents were increased from 15.5% in the first to 81.7% in the second data collection (p < 0.01 after the introduction of the change. The ten pm note is being continued for about two years now. Implementation of ten pm note of organophosphate poisoning patients admitted in medical wards is feasible and appears useful to improve the quality of health care delivery and learning of residents. Keywords: atrophine, audit, audit steps, organophosphate mortality, organophosphate poisoning.

    Full Text Available Abstract Background HIV testing with counseling is an integral component of most national HIV and AIDS prevention strategies in southern Africa. Equity in testing implies that people at higher risk for HIV such as women; those who do not use condoms consistently; those with multiple partners; those who have suffered gender based violence; and those who are unable to implement prevention choices (the choice-disabled are tested and can have access to treatment. Methods We conducted a household survey of 24,069 people in nationally stratified random samples of communities in Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe. We asked about testing for HIV in the last 12 months, intention to test, and about HIV risk behaviour, socioeconomic indicators, access to information, and attitudes related to stigma. Results Across the ten countries, seven out of every ten people said they planned to have an HIV test but the actual proportion tested in the last 12 months varied from 24% in Mozambique to 64% in Botswana. Generally, people at higher risk of HIV were not more likely to have been tested in the last year than those at lower risk, although women were more likely than men to have been tested in six of the ten countries. In Swaziland, those who experienced partner violence were more likely to test, but in Botswana those who were choice-disabled for condom use were less likely to be tested. The two most consistent factors associated with HIV testing across the countries were having heard about HIV/AIDS from a clinic or health centre, and having talked to someone about HIV and AIDS. Conclusions HIV testing programmes need to encourage people at higher risk of HIV to get tested, particularly those who do not interact regularly with the health system. Service providers need to recognise that some people are not able to implement HIV preventive actions and may not feel empowered to get themselves

    Annonaceous acetogenins (ACGs) isolated from Annonaceae plants exhibited a broad range of biological bioactivities such as cytotoxic, antitumoral, antiparasitic, pesticidal and immunosuppresive activities. However, their structures were liable to change at more than 60°C and their extraction yields were low using traditional organic solvent extraction. In the present study, all samples from Annona genus plant seeds were extracted by supercritical carbon dioxide under optimized conditions and a high-performance liquid chromatography (HPLC) method was established for simultaneously determining ten ACGs. All of the ten compounds were simultaneously separated on reversed-phase C18 column (250 mm × 4.6 mm, 5 μm) with the column temperature at 30°C. The mobile phase was composed of (A) methanol and (B) distilled water, the flow rate was 1.0 ml/min and the detection wavelength was set at 220 nm. All calibration curves showed good linear regression (γ>0.9995) within the test range. The established method showed good precision and accuracy with overall intra-day and inter-day variations of 0.99-2.56% and 1.93-3.65%, respectively, and overall recoveries of 95.16-105.01% for the ten compounds analyzed. The established method can be applied to evaluate the intrinsic quality of Annonaceae plant seeds. The determination results recover the content-variation regularities of various ACGs in different species, which are helpful to choose the good-quality Annonaceae plant seeds for anticancer lead compound discovery.

    Full Text Available Ten years after the establishment of the strategic partnership between China and the EU, this relationship has continued to flourish. However, publicly they have often been at odds, and even created doubts about the real existence of the comprehensive strategic partnership. The drawbacks of this relationship in recent years are mainly caused by the increased competitiveness in economy and trade, and the outbreak of quarrels concerning human rights and other areas. Since Sino-EU relations are very important for both parties and the world in general, both sides should find ways to control their conflicts and thus pave the way for their comprehensive strategic partnerships to further flourish.

    Hip shelf arthroplasty is currently considered to be a salvage procedure. The aim of the study is to present outcomes of Bosworth hip shelf arthroplasty in adolescent dysplastic hips with a minimum ten-year follow-up. The basic group comprised 25 hips in 18 patients with the mean age of 31 years (range, 16-52) at the time of operation. Subgroup A included 20 hips that were evaluated prior to operation as spherical, centric hips without osteoarthritic changes (acetabular dysplasia). The heterogeneous subgroup B comprised five hips. Of these, three hips were evaluated as aspheric, without osteoarthritic changes, and two hips as aspheric, with osteoarthritic changes of grade 2 according to Tönnis. In addition, two hips in subgroup B were evaluated as decentred (subluxated), one hip without and one hip with osteoarthritic changes. The mean follow-up was 15 years (range, ten-23). In subgroup A, the positive effect of operation had lasted at the time of the final follow-up for ten to 22 years postoperatively (average follow-up 14 years) in 19 hips. Only one female patient, 46 years old at the time of operation, developed hip osteoarthritis within ten years, that was treated by THA. In subgroup B, a lasting positive effect of operation was recorded in two cases at the time of the final follow-up (12 and 15 years). The third female patient with an aspheric and decentred hip developed severe hip osteoarthritis 21 years after shelf procedure that was treated by THA. In two patients who had hip osteoarthritis already before the operation, the positive effect of the shelf procedure survived over 13 and 20 years. Although hip osteoarthritis progressed, THA was performed as late as 15 and 23 years after the shelf procedure. The mean Harris hip score in 21 hips with a still functional hip shelf was 68 (range, 56-82) before and 90 (range, 76-100) after the surgery. The best outcomes of Bosworth hip shelf arthroplasty may be expected in a dysplastic spherical centred hip

    Full Text Available There are ten deadly errors which make most empty-handed martial-arts techniques against a knife ineffective. The principal error stems from the fact that few present-day martial systems teach the blade. The premise of this article is that to effectively defend against a knife, you need to know how to use one. The purpose of this article is to motivate martial arts instructors to analyze more critically their unarmed knife defense techniques based on a clear understanding of the use of the knife, and to reawaken interest in the blade arts in the martial arts community.

    Full Text Available October 7, 2011, marked a decade since the United States invaded Afghanistan and initiated the Global War on Terrorism (GWOT. While most ten-year anniversary gifts involve aluminum, tin, or diamonds, the greatest gift U.S. policymakers can present American citizens is a reconsideration of the logic that guides America's counterterrorism strategy. Although the United States has successfully averted large-scale domestic terrorist attacks, its inability to grasp the nature of the enemy has cost it dearly in wasted resources and, more importantly, lost lives. Two of the most consistent and glaring policy flaws revolve around the concepts of filling "ungoverned spaces" and installing democracy by force.

    Full Text Available Background: Lumbar radiculopathy is a disease of the spinal nerve root generally accompanied by radicular pain in dermatomal distribution and/or neurologic symptoms. The previous studies were focusing on finding the disability and pain caused due to Lumbar Radiculopathy. This study is focusing on the disability, pain, range of motion of the spine and SLR. The objective of the study is to evaluate the effectiveness of Mckenzie method with TENS on reducing symptoms and disability of Lumbar radiculopathy. Methods: In the present prospective study patients with Lumbar radicular pain due to disc herniation or prolapse at level L4, L5 & S1 were randomized into two groups – Group A and Group B. the study included 40 patients, with 20 in each group. The selection criteria was based on the following - with age group 22-55years, both sexes – male and female, with radicular pain in L4, L5 & S1 dermatomes, disabling leg pain for 6-12 weeks duration, evidence of disc herniation confirmed on MR imaging. The radicular pain was measured using the SLR test, pain was measured using the VAS scale of 0 – 100, disability was measured using the MODI and Lumbar Spine ROM was measured using the MMST. Group-A were treated with McKenzie methods with TENS and Group-B were treated with general exercise with TENS. Results: This study showed that there was a significant reduction of pain on the VAS, improvement in SLR, lumbar spine range of motion using MMST and disability using MODI for both the groups. The statistical analysis found that experimental group showed earlier control of all the outcome measures when compared to controlled group at the end of the 6th week. Conclusion: After 6 weeks of Mckenzie method with TENS intervention for 30 minutes for 5 days in week the statistical analysis concluded that the experimental group had significantly faster rates of reducing the symptoms of lumbar radiculopathy and reducing the disability due to lumbar radiculopathy.

    A ten-month-old girl presented to our clinic with a progressively enlarging congenital mass at the midline suprasternal location. Histopathologic examination revealed a benign cyst with stratified squamous keratinized epithelium with numerous eccrine glands in the sinus wall. The diagnosis was compatible with dermoid cyst. Dermoid cysts of the trunk are rare lesions, but a midline location is characteristic for these congenital masses. A dermoid cyst should be high on the list of differential diagnoses given a unilocular midline cyst in a neonate.

    Our aim is to report the computed tomography (CT) features of the long-term failed renal allograft. Ten patients with failed renal transplants in whom the graft was left in situ underwent CT for various unrelated indications. The majority of the failed grafts showed marked shrinkage and coarse punctate diffuse parenchymal calcifications. Small cysts were seen in four grafts. A long-term failed renal transplant appeared on CT as a small rounded soft tissue mass. The graft was almost always heavily calcified. Lack of awareness of the nature of such a mass may mislead the radiologist in interpreting it as a space-occupying lesion.

  9. Surface boxplots

    KAUST Repository

    Genton, Marc G.

    2014-01-22

    In this paper, we introduce a surface boxplot as a tool for visualization and exploratory analysis of samples of images. First, we use the notion of volume depth to order the images viewed as surfaces. In particular, we define the median image. We use an exact and fast algorithm for the ranking of the images. This allows us to detect potential outlying images that often contain interesting features not present in most of the images. Second, we build a graphical tool to visualize the surface boxplot and its various characteristics. A graph and histogram of the volume depth values allow us to identify images of interest. The code is available in the supporting information of this paper. We apply our surface boxplot to a sample of brain images and to a sample of climate model outputs.

With these methods it has become possible to measure surface vibrations in a wide energy range for all wave vectors in the two-dimensional Brillouin zone and thus to deduce the complete surface phonon dispersion curves. Inelastic atomic beam scattering and electron energy loss spectroscopy have started to play a role in the study of surface phonons similar to the one played by inelastic neutron scattering in the investigation of bulk phonons in the last thirty years. Detailed comparison between experimen­ tal results and theoretical studies of inelastic surface scattering and of surface phonons has now become feasible. It is therefore possible to test and to improve the details of interaction models which have been worked out theoretically in the last few decades. At this point we felt that a concise, co...

    To assess various causes of maternal mortality over a ten year period. Retrospective audit of hospital case records. Tertiary care hospital. Pregnant women who expired in the premises of GTB Hospital. A retrospective audit of case records of maternal deaths was conducted for a ten year period (January 2005 to December 2014). There were a total of 647 maternal deaths out of 1,16,641 live births. Sixty-eight percent (n = 445) of women were aged 21-30 years, while 10.5% (n = 68) were problem and improving the utilization of public health facilities. Preeclampsia/eclampsia and obstetric hemorrhage have been the main causes of maternal mortality for ages. Regular antenatal visits and the judicious training of grassroot level workers to pick-up complications early on in the pregnancy can be an effective way to deal the morbidity and mortality associated with these problems. The Janani Suraksha Yojana (JSY) and Janani Shishu Suraksha Karyakaram (JSSK) in India are pioneer steps in this direction.

    Full Text Available We characterized ectopic gene conversions in the genome of ten hemiascomycete yeast species. Of the ten species, three diverged prior to the whole genome duplication (WGD event present in the yeast lineage and seven diverged after it. We analyzed gene conversions from three separate datasets: paralogs from the three pre-WGD species, paralogs from the seven post-WGD species, and common ohnologs from the seven post-WGD species. Gene conversions have similar lengths and frequency and occur between sequences having similar degrees of divergence, in paralogs from pre- and post-WGD species. However, the sequences of ohnologs are both more divergent and less frequently converted than those of paralogs. This likely reflects the fact that ohnologs are more often found on different chromosomes and are evolving under stronger selective pressures than paralogs. Our results also show that ectopic gene conversions tend to occur more frequently between closely linked genes. They also suggest that the mechanisms responsible for the loss of introns in S. cerevisiae are probably also involved in the gene 3'-end gene conversion bias observed between the paralogs of this species.

    In keeping with the large area of interest comprised within the field of pediatrics, the number and diversity of publications in this field has gradually increased over the last ten years in our country as well as worldwide. The objective of this paper is to offer an analysis of the status of pediatrics publications during those ten years. The publications analyzed were listed in the Thomson Reuters Web of Science and/or published in journals included in the Science Citation Index, the Science Citation Index Expanded and the Social Sciences Citation Index. All of these publications appeared in journals in which at least one pediatrics specialist published between the years 2004 and 2013. It may be seen that Turkey is in fifth place worldwide in terms of the number of studies published in these journals, with 6,134 such publications. The conclusion is that it is necessary for more Turkish studies to be multicenter, to involve international participation and to receive more citations; importance must be attached to the objective of transforming of the knowledge produced by Turkish researchers into a greater number of publications of increased quality.

    Full Text Available Forest health issues are on the rise in the United States, resulting from introduction of alien pests and diseases, coupled with abiotic stresses related to climate change. Increasingly, forest scientists are finding genetic/genomic resources valuable in addressing forest health issues. For a set of ten ecologically and economically important native hardwood tree species representing a broad phylogenetic spectrum, we used low coverage whole genome sequencing from multiplex Illumina paired ends to economically profile their genomic content. For six species, the genome content was further analyzed by flow cytometry in order to determine the nuclear genome size. Sequencing yielded a depth of 0.8X to 7.5X, from which in silico analysis yielded preliminary estimates of gene and repetitive sequence content in the genome for each species. Thousands of genomic SSRs were identified, with a clear predisposition toward dinucleotide repeats and AT-rich repeat motifs. Flanking primers were designed for SSR loci for all ten species, ranging from 891 loci in sugar maple to 18,167 in redbay. In summary, we have demonstrated that useful preliminary genome information including repeat content, gene content and useful SSR markers can be obtained at low cost and time input from a single lane of Illumina multiplex sequence.

    Full Text Available The establishment of democracy in the communist countries, which generated profound social and economic transformation, was accompanied by a decline in fertility. We attempt to provide an overall survey on fertility since 1989 in ten Central and Eastern European Countries, members of the European Union, and to identify the variables which explain the fertility decline. We will use univariate and multivariate statistical analysis to identify disparities between the ten countries, and the variables which explain these differences. Also, we developed a panel econometric model to confirm the hypothesis of a similar pattern of evolution for fertility in these countries and that the decline in fertility can be explained both through demographic and economic variables. The decline in fertility can be explained by economic growth, marriage, divorce, abortion, and migration. The empirical evidence presented in this paper supports the view that the decline in fertility over the 1989s represents the continuation of a longstanding trend of the previous period, according to the demographic transition theory, but its speed and magnitude has been influenced by the new social and economic landscape. These results can be useful for public authorities of the CEE countries to rethinking demographic policies and to ensure the sustainability of demographic growth.

    Plant and microbial toxins are considered bioterrorism threat agents because of their extreme toxicity and/or ease of availability. Additionally, some of these toxins are increasingly responsible for accidental food poisonings. The current study utilized an ELISA-based protein antibody microarray for the multiplexed detection of ten biothreat toxins, botulinum neurotoxins (BoNT) A, B, C, D, E, F, ricin, shiga toxins 1 and 2 (Stx), and staphylococcus enterotoxin B (SEB), in buffer and complex biological matrices. The multiplexed assay displayed a sensitivity of 1.3 pg/mL (BoNT/A, BoNT/B, SEB, Stx-1 and Stx-2), 3.3 pg/mL (BoNT/C, BoNT/E, BoNT/F) and 8.2 pg/mL (BoNT/D, ricin). All assays demonstrated high accuracy (75-120 percent recovery) and reproducibility (most coefficients of variation < 20%). Quantification curves for the ten toxins were also evaluated in clinical samples (serum, plasma, nasal fluid, saliva, stool, and urine) and environmental samples (apple juice, milk and baby food) with overall minimal matrix effects. The multiplex assays were highly specific, with little crossreactivity observed between the selected toxin antibodies. The results demonstrate a multiplex microarray that improves current immunoassay sensitivity for biological warfare agents in buffer, clinical, and environmental samples.

    This Idaho National Laboratory (INL) Ten-Year Site Plan (TYSP) describes the strategy for accomplishing the long-term objective of sustaining the INL infrastructure to meet the Department of Energy Office of Nuclear Energy (DOE-NE) mission: to promote nuclear power as a resource capable of making major contributions in meeting the nation’s energy supply, environmental and energy security needs. This TYSP provides the strategy for INL to accomplish its mission by: (1) linking R&D mission goals to core capabilities and infrastructure requirements; (2) establishing a ten-year end-state vision for INL facility complexes; (3) identifying and prioritizing infrastructure needs and capability gaps; (4) establishing maintenance and repair strategies that allow for sustainment of mission-critical (MC) facilities; and (5) applying sustainability principles to each decision and action. The TYSP serves as the infrastructure-planning baseline for INL; and, though budget formulation documents are informed by the TYSP, it is not itself a budget document.

    Full Text Available Motivation has long been associated with sports engagement. However, to date no research has been performed to understand the domain of motivation among ten-pin bowlers. The purpose of this study was to investigate different types of motivation (i.e., intrinsic vs. extrinsic based on self-determination theory from the perspective of gender and the bowler type (competitive vs. casual. A total of 240 bowlers (104 male, 136 female; 152 competitive, 88 casual with a mean age of 16.61 ± 0.78 years were recruited in Kuala Lumpur. The Sport Motivation Scale, a 28-item self-report questionnaire measuring seven subscales (i.e., intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, extrinsic motivation to identify regulation, extrinsic motivation for introjection regulation, extrinsic motivation to external regulation, and amotivation was administered. Results showed significant differences (t=10.43, df=239, p=0.01 between total scores of intrinsic and extrinsic motivation among tenpin bowlers. There were significant gender differences with respect to intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, and extrinsic motivation to identify regulation. However, no significant bowler type differences were found for either the intrinsic (t=-1.15, df=238, p=0.25 or extrinsic (t=-0.51, df=238, p=0.61 motivation dimensions. In conclusion, our study demonstrated substantial intrinsic motivation for gender effects, but no bowler type effects among adolescent ten-pin bowlers.

    Full Text Available In his article Open Problems in the Philosophy of Information [1] Luciano Floridi presented a Philosophy of Information research program in the form of eighteen open problems, covering the following fundamental areas: Information definition, information semantics, intelligence/cognition, informational universe/nature and values/ethics. We revisit Floridi’s program, highlighting some of the major advances, commenting on unsolved problems and rendering the new landscape of the Philosophy of Information (PI emerging at present. As we analyze the progress of PI we try to situate Floridi’s program in the context of scientific and technological development that have been made last ten years. We emphasize that Philosophy of Information is a huge and vibrant research field, with its origins dating before Open Problems, and its domains extending even outside their scope. In this paper, we have been able only to sketch some of the developments during the past ten years. Our hope is that, even if fragmentary, this review may serve as a contribution to the effort of understanding the present state of the art and the paths of development of Philosophy of Information as seen through the lens of Open Problems.

    Full Text Available The use of acupuncture in inducing delivery has a long history in China. With progress over time, it has been applied in many aspects. For further study of acupuncture in delivery, this paper analyzed the papers using acupuncture in delivery in the past ten years in mainland China. 87 literatures were picked out by searching relevant electronic databases and bibliographies of relevant journals. The analysis showed randomized controlled trials that were the major type of research, while preclinical researches and literature reviews only account for around ten percent, respectively. Clinical researches indicated that acupuncture can relieve labor pain, promote maternal uterine contraction, shorten birth process, and treat postpartum disorders. Preclinical researches found that acupuncture can adjust certain hormones and improve uterus contraction of late-stage pregnant rats. However, due to lack of large multicenter randomized controlled clinical trials, standardized evaluations of clinical effects in clinical researches and detailed mechanism study in preclinical researches and unequivocal conclusions about the effectiveness, efficacy, and mechanisms of acupuncture in this field cannot be obtained from those researches yet. Further clinical and preclinical studies about the use of acupuncture in delivery with improved methodology is still needed.
