An analogue of Wagner's theorem for decompositions of matrix algebras

Wagner's celebrated theorem states that a finite affine plane whose collineation group is transitive on lines is a translation plane. The notion of an orthogonal decomposition (OD) of a classically semisimple associative algebra introduced by the author allows one to draw an analogy between finite affine planes of order n and ODs of the matrix algebra M n (C) into a sum of subalgebras conjugate to the diagonal subalgebra. These ODs are called WP-decompositions and are equivalent to the well-known ODs of simple Lie algebras of type A n-1 into a sum of Cartan subalgebras. In this paper we give a detailed and improved proof of the analogue of Wagner's theorem for WP-decompositions of the matrix algebra of odd non-square order an outline of which was earlier published in a short note in 'Russian Math. Surveys' in 1994. In addition, in the framework of the theory of ODs of associative algebras, based on the method of idempotent bases, we obtain an elementary proof of the well-known Kostrikin-Tiep theorem on irreducible ODs of Lie algebras of type A n-1 in the case where n is a prime-power.

This study examines the structural characteristics of the northern Gulf of California by processing and interpreting ca. 415 km of two-dimensional multi-channel seismic reflection lines (data property of Petróleos Mexicanos PEMEX) collected in the vicinity of the border between the Wagner and Consag basins. The two basins appear to be a link between the Delfín Superior Basin to the south, and the Cerro Prieto Basin to the north in the Mexicali-Imperial Valley along the Pacific-North America plate boundary. The seismic data are consistent with existing knowledge of four main structures (master faults) in the region, i.e., the Percebo, Santa María, Consag Sur, and Wagner Sur faults. The Wagner and Consag basins are delimited to the east by the Wagner Sur Fault, and to the west by the Consag Sur Fault. The Percebo Fault borders the western margin of the modern Wagner Basin depocenter, and is oriented N10°W, dipping (on average) ˜40° to the northeast. The trace of the Santa María Fault located in the Wagner Basin strikes N19°W, dipping ˜40° to the west. The Consag Sur Fault is oriented N14°W, and dips ˜42° to the east over a distance of 21 km. To the east of the study area, the Wagner Sur Fault almost parallels the Consag Sur Fault over a distance of ˜86 km, and is oriented N10°W with an average dip of 59° to the east. Moreover, the data provide new evidence that the Wagner Fault is discontinuous between the two basins, and that its structure is more complex than previously reported. A structural high separates the northern Consag Basin from the southern Wagner Basin, comprising several secondary faults oriented NE oblique to the main faults of N-S direction. These could represent a zone of accommodation, or transfer zone, where extension could be transferred from the Wagner to the Consag Basin, or vice versa. This area shows no acoustic basement and/or intrusive body, which is consistent with existing gravimetric and magnetic data for the region.

[Problems and complications of leg lengthening with the Wagner apparatus].

Herzog, R; Hefti, F

1992-06-01

Since 1971, we have performed 189 leg lengthening procedures using the Wagner method at our institution. The results obtained in the first 26 cases (1971-1973) showed a high complication rate, which led us to reconsider the indications for this procedure. In the present paper, we analyze the results of 37 leg lengthening procedures carried out in 32 patients during the last 10 years (1981-1990) in the children's unit of the orthopedic department of the University of Basle. We found a complication rate of 78%, and in 46% of cases there was more than one major complication. We did not distinguish between "complications" and "problems", because such distinctions are of little importance to the patient. The average age at the time of surgery was 14.8 years, and the average increase in length was 4.3 (2.2-9.2) cm. For each 1 cm of lengthening, an average of 21 days in hospital and 64 days of reduced weight-bearing were needed. Our conclusion is that the Wagner method makes it possible to attain the goal of leg lengthening, but the second step cannot reduce the length of stay in hospital or the length of time the patient needs the help of crutches. Bone remodeling is disturbed. Our preliminary experience with the Ilizarov method is more encouraging.

Full Text Available Il XIX secolo fu un’epoca convulsa per quanto riguarda l’evoluzione del pensiero architettonico. In quanto apice del pensiero illuminista del secolo precedente, tale epoca si manifestò nelle forme dell’architettura storica e allo stesso tempo divenne l’immagine della modernità, stabilendo le basi di quel razionalismo, che avrebbe costruito, ai margini della storia, la sua idea di forma. Tre dei maggiori protagonisti di questo sviluppo, sia per quanto riguarda il loro lavoro di architetti, che come insegnanti, furono Jean-Nicolas-Louis Durand, Julien Guadet e Otto Wagner / The 19th century was a time of upheaval in the development of architectonic thinking. As culmination of the enlightened thinking of the previous century it expressed itself through historical form, and as a reflection of modernity, it established the bases for a rationalist-based architecture that would construct its wish for form outside the margins of history. We highlight the teaching work of three professors and architects in the construction of that thinking: Durand, Guadet and Wagner.

Tectonoestratigraphic and Thermal Models of the Tiburon and Wagner Basins, northern Gulf of California Rift System

Contreras, J.; Ramirez Zerpa, N. A.; Negrete-Aranda, R.

2014-12-01

The northern Gulf of California Rift System consist sofa series faults that accommodate both normal and strike-slip motion. The faults formed a series of half-greens filled with more than 7 km of siliciclastic suc­cessions. Here, we present tectonostratigraphic and heat flow models for the Tiburón basin, in the southern part of the system, and the Wag­ner basin in the north. The models are constrained by two-dimensional seis­mic lines and by two deep boreholes drilled by PEMEX­-PEP. Analysis of the seismic lines and models' results show that: (i) subsidence of the basins is controlled by high-angle normal faults and by flow of the lower crust, (ii) basins share a common history, and (iii) there are significant differences in the way brittle strain was partitioned in the basins, a feature frequently observed in rift basins. On one hand, the bounding faults of the Tiburón basin have a nested geometry and became active following a west-to-east sequence of activation. The Tiburon half-graben was formed by two pulses of fault activity. One took place during the protogulf extensional phase in the Miocene and the other during the opening of Gulf of California in the Pleistocene. On the other hand, the Wagner basin is the result of two fault generations. During the late-to middle Miocene, the west-dipping Cerro Prieto and San Felipe faults formed a domino array. Then, during the Pleistocene the Consag and Wagner faults dissected the hanging-wall of the Cerro Prieto fault forming the modern Wagner basin. Thermal modeling of the deep borehole temperatures suggests that the heat flow in these basins in the order of 110 mW/m2 which is in agreement with superficial heat flow measurements in the northern Gulf of California Rift System.

Statistical ultrasonics: the influence of Robert F. Wagner

Science.gov (United States)

Insana, Michael F.

2009-02-01

An important ongoing question for higher education is how to successfully mentor the next generation of scientists and engineers. It has been my privilege to have been mentored by one of the best, Dr Robert F. Wagner and his colleagues at the CDRH/FDA during the mid 1980s. Bob introduced many of us in medical ultrasonics to statistical imaging techniques. These ideas continue to broadly influence studies on adaptive aperture management (beamforming, speckle suppression, compounding), tissue characterization (texture features, Rayleigh/Rician statistics, scatterer size and number density estimators), and fundamental questions about how limitations of the human eye-brain system for extracting information from textured images can motivate image processing. He adapted the classical techniques of signal detection theory to coherent imaging systems that, for the first time in ultrasonics, related common engineering metrics for image quality to task-based clinical performance. This talk summarizes my wonderfully-exciting three years with Bob as I watched him explore topics in statistical image analysis that formed a rational basis for many of the signal processing techniques used in commercial systems today. It is a story of an exciting time in medical ultrasonics, and of how a sparkling personality guided and motivated the development of junior scientists who flocked around him in admiration and amazement.

The study was conducted to identify modifications in rural spaces in that place, where farmers are facing economic difficulties and have tried to enter tourism business to overcome them. The article analyzes participatory processes as starters to make rural producers and local agents get interested in tourism business, being participation the key factor for tourism planning. An exploratory research was conducted to describe the Municipality and also a bibliographic research. As e result it was observed that the main public agents do not dialog with each other and that partnership with private agents is needed. In spite of this lack of integration, involvement was achieved and it was possible to identify which are the necessary steps for tourism development.

Three physicians are discussed. Sigmund Freud, probably the best-known member of the Vienna School of Medicine, was the path-breaking pioneer in psychoanalysis and psychotherapy. Julius Wagner-Jauregg was a psychiatrist who discovered the link between iodine deficiency and goitre and also developed malaria therapy to treat progressive paralysis caused by syphilis for which he was awarded the Nobel Prize. Karel Wenckebach, the pioneering Dutch cardiologist, is best known for the Wenckebach block. After the Anschluss, fate dealt very different hands to these three physicians. Freud fled to London where he soon died. Wagner-Jauregg, who had some pan-Germanic sympathies as well as views on eugenics, left a controversial legacy. The Dutch cardiologist Wenckebach died in Vienna shortly after his homeland had been invaded in 1940 by that of his hosts. © IMechE 2014.

Full Text Available Methanetrisulfonic acid had been prepared for the first time over 140 years ago, but it was used only scarcely in chemical transformations. In the course of our activities dealing with key-steps of industrial syntheses of vitamins, e.g. economically important vitamin E (acetate, we found that methanetrisulfonic acid is an extremely effective catalyst in a variety of reactions. Examples of its applications are Wagner-Meerwein rearrangements, Friedel-Crafts alkylations and ring closures, as well as acylation reactions. Use of this catalyst in truly catalytic amounts (0.04-1.0 mol% resulted in highly selective transformations and yields over 95%. (Remark by the authors: We are describing only one example each for the various types of reactions. Therefore, it would be more appropriate to write (here and in the Introduction and in the Conclusion sections: “Wagner-Meerwein rearrangement, Friedel-Crafts alkylation and ring closure, as well as acylation reactions”

The wish for annihilation in 'love-death' as collapse of the need for recognition, in Wagner's Tristan und Isolde.

Science.gov (United States)

Bergstein, Moshe

2013-08-01

Wagner's Tristan und Isolde holds a central position in Western music and culture. It is shown to demonstrate consequences of interruption of developmental processes involving the need for recognition of subjectivity, resulting in the collapse of this need into the wish for annihilation of self and other through 'love-death' [Liebestod]. A close reading of the musical language of the opera reveals how this interruption is demonstrated, and the consequent location of identity outside of language, particularly suitable for expression in music. Isolde's dynamics are presented as distinct from that of Tristan, and in contrast to other interpretations of Tristan and Isolde's love as an attack on the Oedipal order, or as a regressive wish for pre-Oedipal union. Isolde's Act I narrative locates the origin of her desire in the protagonists' mutual gaze at a traumatic moment. In this moment powerful and contrasting emotions converge, evoking thwarted developmental needs, and arousing the fantasy of redemption in love-death. By removing the magical elements, Wagner enables a deeper understanding of the characters' positions in relation to each other, each with his or her own needs for recognition and traumatic experiences. These positions invite mutual identifications resulting in rising tension between affirmation of identity and annihilation, with actual death as the only possible psychic solution. The dynamics described in the opera demonstrate the function of music and opera in conveying meaning which is not verbally expressible. Copyright © 2013 Institute of Psychoanalysis.

To report the clinical and molecular findings of a kindred with Wagner syndrome (WS) revealed by intraocular inflammatory features. Eight available family members underwent complete ophthalmologic examination, including laser flare cell meter measurements. Collagen, type II, alpha 1, versican (VCAN), frizzled family receptor 4, low density lipoprotein receptor-related protein 5, tetraspanin 12, and Norrie disease (pseudoglioma) genes were screened with direct sequencing. The index case was initially referred for unexplained severe and chronic postoperative bilateral uveitis following a standard cataract surgery procedure. Clinical examination of the proband revealed an optically empty vitreous with avascular vitreous strands and veils, features highly suggestive of WS. The systematic familial ophthalmologic examination identified three additional unsuspected affected family members who also presented with the WS phenotype, including uveitis for one of them. We identified a novel c.4004-6T>A nucleotide substitution at the acceptor splice site of intron 7 of the VCAN gene that segregated with the disease phenotype. We present a family with WS with typical WS features and intraocular inflammatory manifestations associated with a novel splice site VCAN mutation. Beyond the structural role in the retinal-vitreous architecture, versican is also emerging as a pivotal mediator of the inflammatory response, supporting uveitis predisposition as a clinical manifestation of WS.

Although a number of new species of Babesia/Theileria have been described recently, there are still relatively few reports of species from Africa. In this study based on the evaluation of morphology and phylogenetic relationships, we describe a novel species from Wagner's gerbil, Babesia behnkei n. sp. Rodents (n = 1021) were sampled in four montane valleys (wadies) in 2000, 2004, 2008 and 2012 in the Sinai Mountains, Egypt. The overall prevalence of Babesia spp. was highest in the Wagner's gerbil (Dipodillus dasyurus; 38.7%) in comparison to the prevalence in the spiny mice species, Acomys dimidiatus and A. russatus. Morphological investigations were conducted for the comparison of trophozoites of the novel species of Babesia with the B. microti King's 67 reference strain. Thirty-two isolates derived from D. dasyurus over a 9 year period (2004-2012) from two wadies (29 isolates from Wadi Gebel and 3 from Wadi El-Arbaein) were investigated by microscopic, molecular and phylogenetic analysis. A near-full-length sequence of the 18S rRNA gene and the second internal transcribed spacer (ITS2) region were amplified, sequenced and used for the construction of phylogenetic trees. A novel species of Babesia was identified in two isolated populations of D. dasyurus. Phylogenetic analysis of 18S rDNA and ITS2 sequences revealed that B. behnkei n. sp. is most closely related to B. lengau from cheetahs from South Africa and to Nearctic species found only in North America (the pathogenic B. duncani and B. conradae) and that it is more distant to the cosmopolitan rodent parasite B. microti. Trophozoites of B. behnkei were smaller and less polymorphic than trophozoites of B. microti. Babesia behnkei n. sp. is a novel species of the 'Duncani group' maintained in isolated populations of Dipodillus dasyurus occurring in the Sinai Mountains of Egypt.

A primary control on the geodynamics of rifting is the thermal regime. To better understand the geodynamics of rifting in the northern Gulf of California we systematically measured heat-flow across the Wagner Basin, a tectonically active basin that lies near the southern terminus of the Cerro Prieto fault. The heat flow profile is 40 km long, has a nominal measurement spacing of ∼1 km, and is collocated with a seismic reflection profile. Heat flow measurements were made with a 6.5-m violin-bow probe. Although heat flow data were collected in shallow water, where there are significant temporal variations in bottom water temperature, we use CTD data collected over many years to correct our measurements to yield accurate values of heat flow. After correction for bottom water temperature, the mean and standard deviation of heat flow across the western, central, and eastern parts of the basin are 220 ± 60, 99 ± 14, 889 ± 419 mW m-2, respectively. Corrections for sedimentation would increase measured heat flow across the central part of basin by 40 to 60%. We interpret the relatively high heat flow and large variability on the western and eastern flanks in terms of upward fluid flow at depth below the seafloor, whereas the lower and more consistent values across the central part of the basin are suggestive of conductive heat transfer. Moreover, heat flow across the central basin is consistent with gabbroic underplating at a depth of 15 km and suggests that continental rupture here has not gone to completion.

Let $(X,d)$ be a metric space. In this paper we provide some observations about the fuzzy metric space in the sense of Kramosil and Michalek $(Y,N,/wedge)$, where $Y$ is the set of non-negative real numbers $[0,/infty[$ and $N(x,y,t)=1$ if $d(x,y)/leq t$ and $N(x,y,t)=0$ if $d(x,y)/geq t$.

Application of the Maxwell-Wagner-Hanai effective medium theory to the analysis of the interfacial polarization relaxations in conducting composite films

International Nuclear Information System (INIS)

Adohi, B J-P; Bouanga, C Vanga; Fatyeyeva, K; Tabellout, M

2009-01-01

A new approach to explain the interfacial polarization phenomenon in conducting composite films is proposed. HCl-doped poly(ethylene terephthalate) (PET) and polyamide-6 (PA-6) matrices with embedded polyaniline (PANI) particles as filler were investigated and analysed, combining dielectric spectroscopy and AFM electrical images with the effective medium theory analysis. Up to three relaxation peaks attributed to the interfacial polarization phenomena were detected in the studied frequency range (0.1 Hz-1 MHz). The AFM electrical images revealed that the doped PA-6/PANI composite can be modelled as a single-type particle medium and the PET/PANI one as a two-type particle medium. A simple dielectric loss expression was derived from the Maxwell-Wagner-Hanai mixture equation and was applied to the experimental data to identify the interfaces involved in each of the relaxation peaks. The parameter values (permittivity, conductivity, volume fraction of the PANI particles) were found to agree well with the measured one, hence validating the models.

A Quantum Mermin-Wagner Theorem for a Generalized Hubbard Model

Directory of Open Access Journals (Sweden)

Mark Kelbert

2013-01-01

Full Text Available This paper is the second in a series of papers considering symmetry properties of bosonic quantum systems over 2D graphs, with continuous spins, in the spirit of the Mermin-Wagner theorem. In the model considered here the phase space of a single spin is ℋ1=L2(M, where M is a d-dimensional unit torus M=ℝd/ℤd with a flat metric. The phase space of k spins is ℋk=L2sym(Mk, the subspace of L2(Mk formed by functions symmetric under the permutations of the arguments. The Fock space H=⊕k=0,1,…ℋk yields the phase space of a system of a varying (but finite number of particles. We associate a space H≃H(i with each vertex i∈Γ of a graph (Γ,ℰ satisfying a special bidimensionality property. (Physically, vertex i represents a heavy “atom” or “ion” that does not move but attracts a number of “light” particles. The kinetic energy part of the Hamiltonian includes (i -Δ/2, the minus a half of the Laplace operator on M, responsible for the motion of a particle while “trapped” by a given atom, and (ii an integral term describing possible “jumps” where a particle may join another atom. The potential part is an operator of multiplication by a function (the potential energy of a classical configuration which is a sum of (a one-body potentials U(1(x, x∈M, describing a field generated by a heavy atom, (b two-body potentials U(2(x,y, x,y∈M, showing the interaction between pairs of particles belonging to the same atom, and (c two-body potentials V(x,y, x,y∈M, scaled along the graph distance d(i,j between vertices i,j∈Γ, which gives the interaction between particles belonging to different atoms. The system under consideration can be considered as a generalized (bosonic Hubbard model. We assume that a connected Lie group G acts on M, represented by a Euclidean space or torus of dimension d'≤d, preserving the metric and the volume in M. Furthermore, we suppose that the potentials U(1, U(2, and V are G-invariant. The result

[Dental enamel prisms of Mesopithecus pentelicus Wagner, 1839, compared with recent cercopithecids (Primates: Cercopithecidae)].

The dental enamel prisms of Cercopithecidae were examined by scanning electron microscopy. The main task of this study was to show the prism morphology representatives of different genera as well as their comparison with the fossil Mesopithecus pentelicus Wagner, 1839. The method used to show the enamel prisms was to etch the tooth surface with hydrochloric acid. In this way the outlines of the prisms were better contrasted for the descriptive morphology of the prisms than in etching with phosphoric acid. Two types were determined, in accord with the systematic division into subfamilies. In the subfamily Cercopithecinae elongated slender prisms were dominating, some with pointed, others with truncated tops. Most characteristic of this type were Macaca and Cercopithecus. An exception was Papio hamadryas which had broader, rounded prisms. In this way it differed largely from P. anubis whose prisms were short and mostly triangular. A very interesting fact was that very different patterns were found in P. anubis and P. hamadryas, although these two species are regarded as only one species by many authors. The second subfamily, the Colobinae, was characterized by broader prisms with a rounded shape, nearly as long as wide. Exceptions of the 'Colobine type' were at first Colobus with prisms little longer than wide and secondly Nasalis, with mostly parallel sides and truncated tops of the prisms. The prism outlines of Mesopithecus showed the greatest similarity to those of Presbytis which represents the characteristic 'Colobine type'. This fact confirmed the actual systematic position of the fossil Mesopithecus within the subfamily Colobinae. In addition to previously known primitive features of Mesopithecus within the subfamily of Colobinae, we present here a further concrete, common feature with asiatic Colobines.

Wagner and Co Solartechnik GmbH, member of Deutscher Fachverband Solarenergie e.V. (DFS), was founded in 1979 as an autonomous company by one dormant partner and eight active partners. A 1991 solar collector sales volume of 20,000 m{sup 2} and a market-leading solar power position in Hesse place the company among today's major manufacturers of solar energy systems in the Federal Republic of Germany. In spite of this remarkable achievement the founders' exological philosophy has always been more than a mere product advertising strategy. The fact that the staff of 40 members has made 'ecological thinking' the matter-of-course basis of any of the company's transactions is manifest in the extensions to and equipment of the new 1,300 m{sup 2} production, storage, dispatch and office building the firm has been occupying since September 1991. The adopted scheme of using low-cost, massproduced components from other branches of the industry for solar systems production and provide them with high-quality absorbers to be offered as low-cost kits has been the company's reliable pillar. Meanwhile the reasonably priced materials are also used for pre-assembled lightweight collector production on the company premises. (orig.).

Mermin-Wagner physics, (H ,T ) phase diagram, and candidate quantum spin-liquid phase in the spin-1/2 triangular-lattice antiferromagnet Ba8CoNb6O24

Ba8CoNb6O24 presents a system whose Co2 + ions have an effective spin 1/2 and construct a regular triangular-lattice antiferromagnet (TLAFM) with a very large interlayer spacing, ensuring purely two-dimensional character. We exploit this ideal realization to perform a detailed experimental analysis of the S =1 /2 TLAFM, which is one of the keystone models in frustrated quantum magnetism. We find strong low-energy spin fluctuations and no magnetic ordering, but a diverging correlation length down to 0.1 K, indicating a Mermin-Wagner trend toward zero-temperature order. Below 0.1 K, however, our low-field measurements show an unexpected magnetically disordered state, which is a candidate quantum spin liquid. We establish the (H ,T ) phase diagram, mapping in detail the quantum fluctuation corrections to the available theoretical analysis. These include a strong upshift in field of the maximum ordering temperature, qualitative changes to both low- and high-field phase boundaries, and an ordered regime apparently dominated by the collinear "up-up-down" state. Ba8CoNb6O24 , therefore, offers fresh input for the development of theoretical approaches to the field-induced quantum phase transitions of the S =1 /2 Heisenberg TLAFM.

With the passing of Dr. Galen Wagner, an exceptional collaboration between Maastricht University Medical Center, The Netherlands, and Duke Clinical Research Institute, USA, has come to an end. This article focuses on the background of what Galen coined the Maastricht-Duke bridge (MD-bridge), its merits, limitations and development throughout the years, and his special role. Between 2004 and 2015, 23 Maastricht University medical students and post-graduate students were enrolled in the 4-month research elective, mentored by Galen and the Maastricht co-mentor. They were asked to complete a survey about their MD-bridge experience. Sixteen out of the 23 students responded. None but 1 participant had prior research experience. Following their MD bridge-program most participants published 1 or more manuscripts and/or presented their research in an international setting. They felt they had full responsibility as a leader of their project with all participants developing meaningful skills useful in their current job. Fourteen out of 16 would recommend the MD-bridge experience to others. Participants considered the program of great value for their personal growth and independence, giving a feeling of achievement. In addition, for some participants it led to careers in foreign countries including medical practice and research, or obtaining PhDs. With Galen's impressive career of mentoring students, including the 23 MD-bridge participants, he has left behind an amazing concept of self-development in research and personal life. The successes of the MD-bridge prove that it is possible for students to be young investigators during or just after medical school with the potential to contribute to developing meaningful skills and noteworthy careers. Collaborations between international universities, such as the MD-bridge, are feasible and should be embraced by other institutions. Published by Elsevier Inc.

Differential effects of adding and removing components of a context on the generalization of conditional freezing.

González, Felisa; Quinn, Jennifer J; Fanselow, Michael S

2003-01-01

Rats were conditioned across 2 consecutive days where a single unsignaled footshock was presented in the presence of specific contextual cues. Rats were tested with contexts that had additional stimulus components either added or subtracted. Using freezing as a measure of conditioning, removal but not addition of a cue from the training context produced significant generalization decrement. The results are discussed in relation to the R. A. Rescorla and A. R. Wagner (1972), J. M. Pearce (1994), and A. R. Wagner and S. E. Brandon (2001) accounts of generalization. Although the present data are most consistent with elemental models such as Rescorla and Wagner, a slight modification of the Wagner-Brandon replaced-elements model that can account for differences in the pattern of generalization obtained with contexts and discrete conditional stimuli is proposed.

The synthesis, micro-structure, spectroscopic, and dielectric properties of SrBi{sub 2}(Nb{sub 1-x}A{sub x}){sub 2}O{sub 9} [with A=W, Mo and x = 0, 0.025] ceramics were systematically studied. A relative density of ≥98% was obtained for all the samples using a two-step solid state sintering process. XRD images showed that a single phase layered perovskite structure of SrBi{sub 2}Nb{sub 2}O{sub 9} (SBN) was formed. The orthorhombic structure with A2{sub 1}am phase group was found up to ∝2.5 at.% substitution of W and Mo into the SBN matrix. SEM revealed the rod-like grain structure similar to the Maxwell-Wagner (MW) parallel plate capacitor model in SBN ceramic, whereas smaller heterogeneous grain structure was observed in W and Mo donor doped ceramics. The initial high value of real and imaginary part of relative permittivity also indicated the presence of interfacial MW relaxation in the SBN ceramics. The experimental data fit well to the theoretical data obtained from MW polarization model in SBN ceramics. The possible origin of the difference of the properties present in the doped sample has been explained based on grain size, orientation, and modification done in the ceramic matrices.

Equilibria of perceptrons for simple contingency problems.

Science.gov (United States)

Dawson, Michael R W; Dupuis, Brian

2012-08-01

The contingency between cues and outcomes is fundamentally important to theories of causal reasoning and to theories of associative learning. Researchers have computed the equilibria of Rescorla-Wagner models for a variety of contingency problems, and have used these equilibria to identify situations in which the Rescorla-Wagner model is consistent, or inconsistent, with normative models of contingency. Mathematical analyses that directly compare artificial neural networks to contingency theory have not been performed, because of the assumed equivalence between the Rescorla-Wagner learning rule and the delta rule training of artificial neural networks. However, recent results indicate that this equivalence is not as straightforward as typically assumed, suggesting a strong need for mathematical accounts of how networks deal with contingency problems. One such analysis is presented here, where it is proven that the structure of the equilibrium for a simple network trained on a basic contingency problem is quite different from the structure of the equilibrium for a Rescorla-Wagner model faced with the same problem. However, these structural differences lead to functionally equivalent behavior. The implications of this result for the relationships between associative learning, contingency theory, and connectionism are discussed.

The Imaginary Significations of Modernity

DEFF Research Database (Denmark)

Carleheden, Mikael

2010-01-01

This article deals with the concept of modernity upon which one of the most interesting contemporary theories about modern social change is based - Peter Wagner's theory of successive modernities. Wagner understands modernity as a double imaginary signification which entails a basic tension between...... liberty and discipline. This conception is almost directly taken from Cornelius Castoriadis. I argue that this tension exists in two versions in Castoriadis' philosophy and that the two versions are incompatible. It is further claimed that the two versions reappear in Wagner's theory, which makes his...... theory of successive modernities partly inconsistent. A stance is taken for one of these versions and it is argued that the theory of successive modernities should appropriate that version as its point of departure in order to grasp the history of modernity in a consistent way.

Comparison of the CME-associated shock arrival times at the earth using the WSA-ENLIL model with three cone models

Science.gov (United States)

Jang, S.; Moon, Y.; Na, H.

2012-12-01

We have made a comparison of CME-associated shock arrival times at the earth based on the WSA-ENLIL model with three cone models using 29 halo CMEs from 2001 to 2002. These halo CMEs have cone model parameters from Michalek et al. (2007) as well as their associated interplanetary (IP) shocks. For this study we consider three different cone models (an asymmetric cone model, an ice-cream cone model and an elliptical cone model) to determine CME cone parameters (radial velocity, angular width and source location), which are used for input parameters of the WSA-ENLIL model. The mean absolute error (MAE) of the arrival times for the elliptical cone model is 10 hours, which is about 2 hours smaller than those of the other models. However, this value is still larger than that (8.7 hours) of an empirical model by Kim et al. (2007). We are investigating several possibilities on relatively large errors of the WSA-ENLIL cone model, which may be caused by CME-CME interaction, background solar wind speed, and/or CME density enhancement.

The extrudate swell of HDPE: Rheological effects

Science.gov (United States)

Konaganti, Vinod Kumar; Ansari, Mahmoud; Mitsoulis, Evan; Hatzikiriakos, Savvas G.

2017-05-01

The extrudate swell of an industrial grade high molecular weight high-density polyethylene (HDPE) in capillary dies is studied experimentally and numerically using the integral K-BKZ constitutive model. The non-linear viscoelastic flow properties of the polymer resin are studied for a broad range of large step shear strains and high shear rates using the cone partitioned plate (CPP) geometry of the stress/strain controlled rotational rheometer. This allowed the determination of the rheological parameters accurately, in particular the damping function, which is proven to be the most important in simulating transient flows such as extrudate swell. A series of simulations performed using the integral K-BKZ Wagner model with different values of the Wagner exponent n, ranging from n=0.15 to 0.5, demonstrates that the extrudate swell predictions are extremely sensitive to the Wagner damping function exponent. Using the correct n-value resulted in extrudate swell predictions that are in excellent agreement with experimental measurements.

Dielectric dispersion of porous media as a fractal phenomenon

Science.gov (United States)

Thevanayagam, S.

1997-09-01

It is postulated that porous media is made up of fractal solid skeleton structure and fractal pore surface. The model thus developed satisfies measured anomalous dielectric behavior of three distinctly different porous media: kaolin, montmorillonite, and shaly sand rock. It is shown that the underlying mechanism behind dielectric dispersion in the kHz range to high MHz range is indeed Maxwell-Wagner mechanism but modified to take into account the multiphase nature of the porous media as opposed to the traditional two-phase Maxwell-Wagner charge accumulation effect. The conductivity of the surface water associated with the solid surface and charge accumulation across the surface irregularities, asperity, and bridging between particles at the micro-scale-level pores are shown to contribute to this modified Maxwell-Wagner mechanism. The latter is dominant at low frequencies. The surface water thickness is calculated to be about 2-6 nm for a variety of porous media.

A note on oblique water entry

KAUST Repository

Moore, M. R.

2012-10-02

A minor error in Howison et al. (J. Eng. Math. 48:321-337, 2004) obscured the fact that the points at which the free surface turns over in the solution of the Wagner model for the oblique impact of a two-dimensional body are directly related to the turnover points in the equivalent normal impact problem. This note corrects some of the earlier results given in Howison et al. (J. Eng. Math. 48:321-337, 2004) and discusses the implications for the applicability of the Wagner model. © 2012 Springer Science+Business Media B.V.

La incorporación y traducción a su producción artística de estos nuevos motivos iconográficos, lo convierten en uno de los mejores receptores de las formas modernistas en España. Como ejemplo de ello, voy a estudiar los primeros dibujos que realizó sobre la imaginería wagneriana para Blanco y Negro, en una temática la de las óperas de Richard Wagner, que tenían en esos momentos su mayor repercusión en la capital con el estreno de sus obras más influyentes.By the late nineteenth-century, Eulogio s Várela works can be explained by the use of the new styles like Symbolism and its later versión, the Art Nouveau. His contribution is quite remarkable in spanish graphic arts and specially in Madrid. Eulogio Várela brought in these new iconographic motives and reinterpretated them and so then he became one of the best followers of Modernism in Spain. The aim of this paper is to pointed out this hypoteses by examining Várela s first designs for "Blanco y Negro" where he uses iconographics elements from Wagner s music. The influence of Wagner on Várela 's works is not strange since the first performances of Wagner s music-dramma were being succesful in the capital.

Maximum Entropy and Probability Kinematics Constrained by Conditionals

Directory of Open Access Journals (Sweden)

Stefan Lukits

2015-03-01

Full Text Available Two open questions of inductive reasoning are solved: (1 does the principle of maximum entropy (PME give a solution to the obverse Majerník problem; and (2 isWagner correct when he claims that Jeffrey’s updating principle (JUP contradicts PME? Majerník shows that PME provides unique and plausible marginal probabilities, given conditional probabilities. The obverse problem posed here is whether PME also provides such conditional probabilities, given certain marginal probabilities. The theorem developed to solve the obverse Majerník problem demonstrates that in the special case introduced by Wagner PME does not contradict JUP, but elegantly generalizes it and offers a more integrated approach to probability updating.

An open circuit voltage equation enabling separation of cathode and anode polarization resistances of ceria electrolyte based solid oxide fuel cells

Science.gov (United States)

Zhang, Yanxiang; Chen, Yu; Yan, Mufu

2017-07-01

The open circuit voltage (OCV) of solid oxide fuel cells is generally overestimated by the Nernst equation and the Wagner equation, due to the polarization losses at electrodes. Considering both the electronic conduction of electrolyte and the electrode polarization losses, we express the OCV as an implicit function of the characteristic oxygen pressure of electrolyte (p* [atm], at which the electronic and ionic conductivities are the same), and the relative polarization resistance of electrodes (rc = Rc/Ri and ra = Ra/Ri, where Ri/c/a [Ωcm2] denotes the ionic resistance of electrolyte, and the polarization resistances of cathode and anode, respectively). This equation approaches to the Wagner equation when the electrodes are highly active (rc and ra → 0), and approaches to the Nernst equation when the electrolyte is a purely ionic conductor (p* → 0). For the fuel cells whose OCV is well below the prediction of the Wagner equation, for example with thin doped ceria electrolyte, it is demonstrated that the combination of OCV and impedance spectroscopy measurements allows the determination of p*, Rc and Ra. This equation can serve as a simple yet powerful tool to study the internal losses in the cell under open circuit condition.

Mineralogical characterization of Greda clays and monitoring of their phase transformations on thermal treatment

Chavez Panduro, E.; Bravo Cabrejos, J.

2010-01-01

The mineralogical characterization of two clay samples from the Central Andean Region of Peru, denominated White Greda and Red Greda, is reported. These clays contain the clay minerals mica and illite respectively. Both clays were treated thermally in an oxidising atmosphere under controlled conditions up to 1,100 deg. C with the purpose of obtaining information about structural changes that may be useful for pottery manufacture. X-ray fluorescence was used for the elemental characterization of the samples and X-ray diffractometry was used to determine the collapse and formation of the mineral phases present in the samples caused by thermal treatment. At temperatures above 1,000 deg. C it is observed the formation of spinel in the case of White Greda and of hematite, corundum and cristobalite in the case of Red Greda. Room temperature transmission Moessbauer spectroscopy allowed the monitoring of the variation of the hyperfine parameters with the thermal treatment temperature; In the case of the evolution of the quadruple splitting of the paramagnetic Fe 3+ sites with temperature, in both clays, the analyses reproduced results such as the 'camel back' curve shape, found by other workers (Wagner and Wagner, Hyperfine Interact 154:35-82, 2004; Wagner and Kyek, Hyperfine Interact 154:5-33, 2004).

Flat plate approximation in the three-dimensional slamming; Heiban kinji ni yoru sanjigen suimen shogeki keisanho ni tsuite

Toyama, Y. [Mitsui Engineering and Shipbuilding Co. Ltd., Tokyo (Japan)

A slamming load generated by interactive motions between a ship body and water face is an important load in ensuring safety of the ship. A flat plate approximation developed by Wagner is used as a two-dimensional slamming theory, but it has a drawback in handling edges of a flat plate. Therefore, an attempt was made to expand the two-dimensional Wagner`s theory to three dimensions. This paper first shows a method to calculate water face slamming of an arbitrary axisymmetric body by using circular plate approximation. The paper then proposes a method to calculate slamming pressure distribution and slamming force for the case when shape of the water contacting surface may be approximated by an elliptic shape. Expansion to the three dimensions made clear to some extent the characteristics of the three-dimensional slamming. In the case of two dimensions or a circular column for example, the water contacting area increases rapidly in the initial stage generating large slamming force. However, in the case of three dimensions, since the water contacting area expands longitudinally and laterally, the slamming force tends to increase gradually. Maximum slamming pressure was found proportional to square of moving velocity in a water contacting boundary in the case of three dimensions, and similar to stagnation pressure on a gliding plate. 12 refs., 17 figs., 1 tab.

王弼《老子注》的詮釋辨證/ Interpretative Dialectics of Wang Bi’s Exegesis of Lao-Tzu

Directory of Open Access Journals (Sweden)

Jung-Tao TSAI

2012-09-01

Wang Bi, the most prominent scholar of metaphysics of the Wei and Jin Dynasties, was an unprecedented genius throughout the history of Chinese philosophy. In this article, the author examines the brilliant contributions made by Lin Li Zhen, Yu Dun Kang and Rudolf G. Wagner, who are noticed for their research of Exegesis of Lao-Tzu. It is a synthesis of the directions of investigation, approaches, and significant findings they have come up with. Among the three interpretations, Lin focuses on the explanation of Wang’s metaphysic thinking while Yu emphasizes Wang’s secular concerns by proposing the “philosophy of thoroughness” and political holism. As for Wagner, he approaches this work with the views of linguistic philosophy and suggests refined stylistics as interpretative strategy, which functions to enrich the textual contents.

Mass, energy, entropy and exergy rate balance in a ranque-hilsh vortex tube

Directory of Open Access Journals (Sweden)

Edorta Carrascal

2013-12-01

Full Text Available The purpose of this paper is to exhibit a laboratory practicum designed for the subject of Thermodynamics at the Department of Thermal Engineering of the University of the Basque Country. With reference to one of the problems stated in the text of Moran, Shapiro, Boettner, Bailey (2012, the balances of mass, energy, entropy and exergy are applied in a particular Control Volume, and the ideal gas model is used. Using a Ranque-Hilsh vortex tube (Ranque, 1934, the division of a compressed air flow into two streams at a lower pressure is achieved; one hot  whose temperature can exceed 100 °C and another cold that can reach temperatures below -40 °C. Therefore an air flow is divided into two, one hot and one cold stream, without any thermal interaction with hot or cold focuses. The vortex tube operation can serve to expose the bases of the first and second law of thermodynamics. Even, this practical lab can be used to give sense to one of the most known theoretical experiments in thermodynamics, such as the one of Maxwell's demon (Lewins & Bejan, 1999; Liew, Zeegers, Kuerten & Michalek, 2012. On the other hand once a compressed air source is provided, the material needed to prepare the lab is simple and affordable and it has a very interesting and suggestive appeal.

Evaluation of self-interaction parameters from binary phase diagrams

International Nuclear Information System (INIS)

Ellison, T.L.

1977-10-01

The feasibility of calculating Wagner self-interaction parameters from binary phase diagrams was examined. The self-interaction parameters of 22 non-ferrous liquid solutions were calculated utilizing an equation based on the equality of the chemical potentials of a component in two equilibrium phases. Utilization of the equation requires the evaluation of the first and second derivatives of various liquidus and solidus data at infinite dilution of the solute component. Several numerical methods for evaluating the derivatives of tabular data were examined. A method involving power series curve fitting and subsequent differentiation of the power series was found to be the most suitable for the interaction parameter calculations. Comparison of the calculated self-interaction parameters with values obtained from thermodynamic measurements indicates that the Wagner self-interaction parameter can be successfully calculated from binary phase diagrams

Using the results of Smith, Solmon, and Wagner [K. Smith, D. Solomon, S. Wagner, Practical and mathematical aspects of the problem of reconstructing objects from radiographs, Bull. Amer. Math. Soc. 83 (1977) 1227-1270] and Nelson and Neumann [S. Nelson, M. Neumann, Generalizations of the projection method with application to SOR theory for Hermitian positive semidefinite linear systems, Numer. Math. 51 (1987) 123-141] we derive new estimates for the speed of the alternating projection method and its relaxed version in . These estimates can be computed in at most O(m3) arithmetic operations unlike the estimates in papers mentioned above that require spectral information. The new and old estimates are equivalent in many practical cases. In cases when the new estimates are weaker, the numerical testing indicates that they approximate the original bounds in papers mentioned above quite well.

Hoch, M.

1988-01-01

The Hoch-Arpshofen model is combined with the Schottky-Wagner disorder model to describe first binary liquid systems, where a very stable solid protrudes into the liquid. We analyze the systems K-I 2 , Cs-I 2 , U-UO 3 , Ag-S and Al-Sb. The system Al-Sb can be described as Al-Sb and as Al-AlSb-Sb. Then we examine the Al-Co, Al-Ni, and Al-Fe systems to describe the stable compounds CoAl, NiAl, and FeAl, which all have a wide homogeneity range in the solid state. Here the Schottky-Wagner model is sufficient. Finally we describe a model which treats the influence of these stable binary compounds in ternary and larger systems such as Al-Cr-Ni and Al-Cr-Fe, again in the solid state. (orig./IHOE) [de

Introduction Diabetic foot infections are a major cause of non-traumatic amputations. The role of anaerobes in the prognosis of these infections is particularly unclear. This study was conducted with the aim of correlating microbiological profiles with clinical outcomes in these diabetic foot ulcer patients. Methodology This prospective observational study was done in a tertiary care centre in South India. All patients admitted with diabetic foot ulcers for two years were included in the study. Tissue biopsies were collected from the ulcer for aerobic and anaerobic cultures. The patients were grouped as those with aerobic infection alone (anaerobe negative) and those with mixed aerobic and anaerobic infections (anaerobe positive). Anaerobic culture was performed using the Robertson cooked meat (RCM) medium. The ulcer of the foot was described with respect to site, size, duration, history of previous amputation(s), and history of number and class of antibiotic intake prior to hospitalization. Clinical course and Wagner's grades of the diabetic foot ulcers were compared for aerobic and anaerobic infections. Results A total of 104 patients were included in the study. There were no significant differences between the two groups with regards to duration of diabetes, random blood sugar (RBS) at the time of admission, compliance to drugs, and mode of blood sugar control and prior intake of antibiotics. Patients with anaerobic infections were found to have a higher incidence of fever in this study (38.1% vs. 14.5%; p = 0.0057), as compared to patients with aerobic infections. More than half of the patients in the anaerobic infection group presented with Wagner's grade IV and above, as compared to the aerobic infection group (59.5% vs. 32.2%; p = 0.0059), which was statistically significant. Patients with anaerobic infections also had high numbers of major and minor amputations when compared to patients with aerobic infections. Conclusion Septic diabetic foot patients with

Towards a history of operatic psychoanalysis.

Science.gov (United States)

Carpenter, Alexander

2010-01-01

This paper examines the history of the trope of psychoanalytic therapy in musical dramas, from Richard Wagner to Kurt Weill, concluding that psychoanalysis and the musical drama are, in some ways, companions and take cues from each other, beginning in the mid-19th century. In Wagner's music dramas, psychoanalytic themes and situations - specifically concerning the meaning and analysis of dreams - are presaged. In early modernist music dramas by Richard Strauss and Arnold Schoenberg (contemporaries of Freud), tacit representations of the drama of hysteria, its aetiology and "treatment" comprise key elements of the plot and resonate with dissonant musical soundscapes. By the middle of the 20th century, Kurt Weill places the relationship between analyst and patient in the foreground of his musical "Lady in the Dark," thereby making manifest what is latent in a century-spanning chain of musical works whose meaning centres, in part, around representations of psychoanalysis.

2017-08-22

In this randomized controlled trial, diabetic patients with foot ulcers (Wagner grades 1 and 2) were randomly assigned to conventional therapies for diabetic foot ulcer plus topical propolis ointment (5%; twice daily) or conventional therapies alone. The process of ulcer healing was observed during 4 weeks and compared between the two groups regarding the size, erythema, exudates, white blood cell (WBC) count and erythrocyte sedimentation rate (ESR). The process of ulcer size reduction during the four-week period of study was significantly different between the groups. However, this difference was not significant between the third and fourth weeks. There was no significant difference between two groups regarding erythema and exudate reduction as well as WBC count and ESR. Administration of topical propolis ointment in addition to the conventional treatments of diabetic foot ulcer could reduce the size of ulcers with Wagner grades 1 and 2.

Full Text Available Introduction. The epidermal growth factor (EGF; HeberprotP ® is the new treatment for deep persistent diabetic foot ulcers (Wagner grade 3–4. The effectiveness of EGF measured as the reduction of the time to complete granulation of tissue lesions was confirmed in randomised clinical trials, but the cost of this new treatment is high. Aim. To analyze the costs and outcomes of the use of EGF (Heberprot-P® for the treatment of DFU in high- ly specialized medical institutions. Material and methods. We tested the hypothesis that the use of Heberprot-P® in diabetic foot ulcers – DFU – (Wagner grade 3–4 would reduce the rate of amputations and increase survival at acceptable cost for the Russian healthcare system. We used the data from international published literature to construct mathematical model representing clinical outcomes in the cohort of patients treated with only standard methods or standard methods in combination with Heberport-P®. We calculated direct costs associated with both strategies of treatment taking into account the risk of amputation. Results. The use of Heberprot-P® may prevent 52 amputations and save 29.54 years of life in a cohort of 100 DFU patients (Wagner grade 3–4. The incremental costs of EGF treatment were RUR 1.170.000 per life year gained and did not exceed the accepted threshold of less than three times GDP per capita. Conclusion. Mathematic modelling demonstrated the feasibility of introduction of EGF in combination with standard treatment for DFU in highly specialized medical institutions.

It contains different care variants for non communicable diseases and similarities to the Cuban pattern of Primary Health care, since all those paradigms could be used as a catalyst for a worldwide future change, keeping in mind that they share coincidence points.

Effective permittivity of random composite media: A comparative study

International Nuclear Information System (INIS)

Prasad, Ashutosh; Prasad, K.

2007-01-01

In the present study, experimental data for effective permittivity of amorphous, polycrystalline thick films, and ceramic form of samples, taken from the literature, have been chosen for their comparison with those yielded by different mixture equations. In order to test the acceptability of dielectric mixture equations for high volume fractions of the inclusion material in the mixture, eleven such equations have been chosen. It is found that equations given by Cuming, Maxwell-Wagner, Webmann, Skipetrov and modified Cule-Torquato show their coherence and minimal deviation from the experimental results of permittivity for all the chosen test materials almost over the entire measurement range of volume fractions. It is further found that Maxwell-Wagner, Webmann, and Skipetrov equations yielded equivalent results and consequently they have been combined together and reckoned as a single equation named MWWS. The study revealed that the Cuming equation had the highest degree of acceptability (errors <±1-5%) in all the cases

Structure and Stratigraphy of the Rift Basins in the Northern Gulf of California: Results from Analysis of Seismic Reflection and Borehole Data.

Science.gov (United States)

Martín, A.; González, M.; Helenes, J.; García, J.; Aragón, M.; Carreño, A.

2008-12-01

The northern Gulf of California contains two parallel, north-south trending rift basin systems separated by a basement-high. The interpretation of several exploration wells, and ~4500 km of seismic reflection data from PEMEX (Mexican national oil company) indicate that the tectonically active basins to the west (Wagner- Consag and Upper Delfin basins) may have initiated synchronously with the now abandoned Tiburón- Tepoca-Altar basins to the east in the Sonora margin. In both basin systems the lower sequence (A) is marine mudstone-siltstone, has parallel reflectors and a largely uniform thickness that reaches up to1.5 km, and gradually pinches out toward the lateral margins. This suggests that the unit was deposited prior to their segmentation by transtensional faulting. Marine microfossils from borehole samples from sequence A in the Tiburón and Consag basins indicates middle Miocene (>11.2 Ma) proto-Gulf conditions. Sequence B conformably overlies sequence A, and is characterized by up to 2 km growth strata with a fanning geometry that show a clear genetic relationship to the major transtensional faults that control the segmentation of the two basin systems. Sequence C in the Tiburón and Tepoca basins is comparatively thin (<800 m) and includes several unconformities, but is much less affected by faulting. In contrast, sequence C in the active Wagner, Consag and Upper Delfin basin is a much thicker (up to 2 km) growth sequence with abundant volcanic intrusions. Marked variations in sequence C in the different basin systems clearly demonstrate a major westward shift of deformation and subsidence at this time. The modern depocenter in Wagner-Consag basins is controlled by the Consag and Wagner faults, which trend parallel to the north ~20 km apart, and show opposite normal offset. These two faults merge at an oblique angle (70°-50°, respectively) into the Cerro Prieto transform fault to the north and likely accommodate an important amount of dextral shear. To

Full Text Available Going by Adolph Wagner’s theory, increased in public expenditure would have a significant influence growth. However, the endogenous growth theories posit that public sector either has direct or indirect impacts on economic growth. It is on this premise, we seek to examine and validate Wagner’s theory on the impact of current, investment and transfer expenditures on economic growth over the periods 1975-2014 for Turkey, using Johansen co-integration test and Granger causality test. Findings confirm Wagner’s law through the existence of a long term relationship between the variables, while public expenditures display a significant positive impact on economic growth.

Encabo Fernández, Enrique

2011-12-01

Full Text Available The Wagnerian movement in Murcia had to overcome some initial resistance. Nonetheless, this movement would have the same characteristics as in other places: a bourgeois, urban movement linked to the idea of modernity and progress. Two stages can be distinguished in the assimilation of Wagnerian music in Murcia. The fi rst stage, in which Wagner’s music is more often read than played; this initial phase would end with the representation in 1890 of the opera Lohengrin in Murcia. In the second stage, the audience in Murcia would have the opportunity to enjoy a more symphonic Wagner thanks to the work of symphonic musical ensembles (bands and chamber groups and the concerts offered (from 1910 by the Orquesta Sinfónica de Madrid.

El movimiento wagneriano en Murcia tuvo que superar algunas reticencias iniciales. A pesar de ello, revistió las mismas características que en otros lugares: movimiento burgués, urbano y ligado a la idea de modernidad y progreso. Podemos distinguir dos etapas en el movimiento wagneriano en Murcia; una primera, en la que Wagner se lee más que se escucha; esta primera etapa culmina con la representación en Murcia de la ópera Lohengrin en 1890. A partir de este momento, comienza la segunda etapa, en la que los murcianos tienen la oportunidad de disfrutar un Wagner más sinfónico que operístico, gracias a la acción de las agrupaciones musicales de la ciudad (bandas y grupos de cámara y los conciertos (a partir de 1910 de la Orquesta Sinfónica de Madrid.

Full Text Available Objectives: To describe the microbiological profile and clinical outcomes of diabetic foot ulcers of inpatients of a tertiary university hospital, at Ceara, Brazil. Methods: We conducted a retrospective analysis of medical charts data of all diabetic inpatients of the Endocrine and Diabetes Unit of Walter Cantídio University Hospital (Federal University of Ceará, admitted from January, 2006 to June, 2007 for severe foot ulcers (minimum of grade 2 of Wagner`s classification, which were refractory to ambulatory treatment. Clinical data from each patient were recorded (sex, age, diabetes duration, and comorbidities as well as microbiological characteristics of foot ulcers and surgical (amputations material. Results: We identified 17 diabetic patients, all type 2, aged 58.11 ± 10.8 years and 12.4 ± 8.4 years of disease, 58.8% male. Of ulcers, 41.1% were grade 2; 35.2% grade 3; 11.7% grade 4 and 11.7% grade 5 of Wagner; 64.7% with less than 3 months of evolution. Debridement was performed in 82.3% of patients and amputation in 47%; osteomyelitis was identified in 47% of cases. All patients started empiric antibiotic therapy, where ciprofloxacin/metronidazole was the most used scheme (76.5%. Cultures were negative in 12.5% of the patients. In the positive ones, the most prevalent bacterial pathogens detected in the culture materials were: S. aureus (57.1%; S. viridans (28.7%; P. aeruginosas (28.7%; M. morganii (28.7%. The majority (75% of isolated S. aureus were methicillin-resistant, but were sensitive to vacomicin. Conclusion: We observed the presence of polymicrobial flora with a large number of multiresistant pathogens and high prevalence of osteomyelitis and amputations in diabetic patients with severe ulcers, neuropathy and peripheral vascular disease.

Procalcitonin and proinflammatory parameters in diabetic foot infection as new predictive factor

2017-09-01

Diabetic foot is a common complication of diabetes due to changes in blood vessels and nerves, often leads to ulceration and subsequent limb amputation if not treated early. A new diagnostic marker of bacterial infections is procalcitonin. C-reactive protein, Interleukin1β, Interleukin-6 and tumor necrosis factor-α as proinflammatory parameters increased in Diabetic foot infection. We evaluated above parameters in patients with diabetic foot infections in different grades. A total of 130 diabetic patients were enrolled in this case control study between June 2011 and March 2012 in Rizgary, Emergency and Hawler Teaching Hospitals, 90 of them with diabetic foot lesion as a patient group. 40 without foot lesion, as a patient control and 20 individuals as healthy control. Assessment of above parameters in sera of study groups and also bacteriological tests (bacterial isolation and identification) were done. Serum procalcitonin levels significantly increased in patients with diabetic foot with higher Wagner grades (III, IV and V) (0.28 ± 0.04, 0.30 ± 0.07 and 0.60 ± 0.11) respectively (Pfoot ulcer based on Wagner classification system was also associated with circulating levels of C-reactive protein, Interleukin1β, Interleukin-6 and tumor necrosis factor-α (G III, IV and V) (5.36 ± 0.70, 6.38 ± 0.65, and 9.13 ± 0.88), (1.21 ± 0.08, 1.56 ± 0.16 and 2.02 ± 0.07), (23.02 ± 2.98, 36.32 ± 5.75 and 43.36 ± 6.16), and (215.39 ± 16.8, 259.21 ± 40.7 and 398.45 ± 33.4) respectively (Pdiabetic foot patients may be a procalcitonin especially in those with higher Wagner grades and with polymicrobial infection.

Education-growth dynamics for Australia: A case study approach

2015-04-01

Full Text Available The main focus of this research is to establish the relevancy of the Keynesian theory in explaining education expenditure on the economy of Austria using a case study approach. Wagner (1890 and Keynes (1936 have been for a long time been the two major theorists on the relationship between education expenditure and economic growth. Both theoretical and empirical literature review concludes that the two variables relate to each other in two distinct ways, the popular one being that education boost the economy (Keynes view followed by the Wagner view that says it is the economy that is doing well that pushes investment in education. A case study review for Austria clearly shows that an increase in education expenditure does not only constitute a significant portion of the GDP per capita in Austria but also provided a positive influence on economic growth and development. The author recommends Austria policymakers and responsible authorities to up their education development programmes and budgets in order to lay a strong foundation for sustainable economic growth and prosperity.

Normative and descriptive accounts of the influence of power and contingency on causal judgement.

Science.gov (United States)

Perales, José C; Shanks, David R

2003-08-01

The power PC theory (Cheng, 1997) is a normative account of causal inference, which predicts that causal judgements are based on the power p of a potential cause, where p is the cause-effect contingency normalized by the base rate of the effect. In three experiments we demonstrate that both cause-effect contingency and effect base-rate independently affect estimates in causal learning tasks. In Experiment 1, causal strength judgements were directly related to power p in a task in which the effect base-rate was manipulated across two positive and two negative contingency conditions. In Experiments 2 and 3 contingency manipulations affected causal estimates in several situations in which power p was held constant, contrary to the power PC theory's predictions. This latter effect cannot be explained by participants' conflation of reliability and causal strength, as Experiment 3 demonstrated independence of causal judgements and confidence. From a descriptive point of view, the data are compatible with Pearce's (1987) model, as well as with several other judgement rules, but not with the Rescorla-Wagner (Rescorla & Wagner, 1972) or power PC models.

Alphons Diepenbrock and the European world of composers at the fin-de-siècle

van der Leeuw Gerard

2002-01-01

Full Text Available The article consists of three parts. In the first part the author gives a survey of the large artistic renewal that took place in the Netherlands around 1900. Special attention is given to "de beweging van Tachtig"(the movement of the "Tachtigers", a renewal movement in literature in which the composer Alphons Diepenbrock was involved. In the second part a short description of the life and work of this most important Dutch composer of the end of the nineteenth century is given. In his early years Diepenbrock orientated himself to composers like Wagner, especially around the First World War (in which the Netherlands remained a neutral country, and he became a fervent admirer of French art. His music is a unique synthesis of Wagner's chromaticism, the word-bound rhythms of plain-chant and the polyphonic music of the old Flemish schools of Ockeghem and Josquin. In the third part the author deals with a couple of Diepenbrock's (artistic contacts. There are highlights on Mahler, Schönberg and Debussy, primarily based on their correspondence.

Full Text Available An empirical study to investigate the effects of thinking styles on emotional intelligence among employees of agriculture industry in east Azerbaijan province. The proposed study uses a standard thinking style questionnaire originally developed by Sternberg and Wagner (1992 [Sternberg, R. J., & Wagner, R. K. (1992. Thinking styles inventory. Unpublished test, Yale University]. There are 716 employees working for this agriculture-based unit and the study uses random sampling technique and chooses 255 employees for this study. Cronbach alpha has been used to verify the overall questionnaire and different tests such as Kolmogorov-Smirnov and Pearson correlation test are used to examine different hypotheses of this survey. The results indicate there is positive and meaningful relationship between thinking style and emotional intelligence. We can also confirm that four thinking style’s components including functions, levels, scope and learning have meaningful impact on emotional intelligence when the level of significance is five or even one percent. However, forms did not have any meaningful impact on emotional intelligence.

IVIVC from Long Acting Olanzapine Microspheres

2014-01-01

Full Text Available In this study, four PLGA microsphere formulations of Olanzapine were characterized on the basis of their in vitro behavior at 37°C, using a dialysis based method, with the goal of obtaining an IVIVC. In vivo profiles were determined by deconvolution (Nelson-Wagner method and using fractional AUC. The in vitro and in vivo release profiles exhibited the same rank order of drug release. Further, in vivo profiles obtained with both approaches were nearly superimposable, suggesting that fractional AUC could be used as an alternative to the Nelson-Wagner method. A comparison of drug release profiles for the four formulations revealed that the in vitro profile lagged slightly behind in vivo release, but the results were not statistically significant (P0.96 between in vitro release and in vivo measurements confirmed the excellent relationship between in vitro drug release and the amount of drug absorbed in vivo. The results of this study suggest that proper selection of an in vitro method will greatly aid in establishing a Level A IVIVC for long acting injectables.

Bayreuther festspiele as a field for application of Peter Berger’s and Thomas Luckmann’s Theory of social construction of reality

Directory of Open Access Journals (Sweden)

Jeremić-Molnar Dragana

2006-01-01

Full Text Available The Stage festival in Bauyeuth (Bayreuther Festspiele, established in 1876. by German composer Richard Wagner (1813-1883, is, even nowadays, a complex and unique phenomenon which continually attracts the attention of scholars from various (mainly humanistic and social scientific fields. In many different methodological approaches to Bayreuther Festspiele, including those made by social scientists, one can not find the application of the sociological theory of Peter Berger and Thomas Luckmann. However, one has to bare in mind the important fact that Richard Wagner founded his completely innovative festive institution mainly in order to carry out and to spread his regenerative Weltanschauung - already formulated in his numerous theoretical writings and incorporated into his musical dramas. The fact that Wagner’s Weltanschauung was based on the idea of changing the reality of everyday life by constructing the new reality, is of equal importance. Considering all this, it becomes appropriate to explain Wagner’s motivation for establishing the stage festival, as well as his idea of festival, from the standpoint of the theory of social construction of reality.

Time-Dependent-Asymmetric-Linear-Parsimonious Ancestral State Reconstruction.

Science.gov (United States)

Didier, Gilles

2017-10-01

The time-dependent-asymmetric-linear parsimony is an ancestral state reconstruction method which extends the standard linear parsimony (a.k.a. Wagner parsimony) approach by taking into account both branch lengths and asymmetric evolutionary costs for reconstructing quantitative characters (asymmetric costs amount to assuming an evolutionary trend toward the direction with the lowest cost). A formal study of the influence of the asymmetry parameter shows that the time-dependent-asymmetric-linear parsimony infers states which are all taken among the known states, except for some degenerate cases corresponding to special values of the asymmetry parameter. This remarkable property holds in particular for the Wagner parsimony. This study leads to a polynomial algorithm which determines, and provides a compact representation of, the parametric reconstruction of a phylogenetic tree, that is for all the unknown nodes, the set of all the possible reconstructed states associated with the asymmetry parameters leading to them. The time-dependent-asymmetric-linear parsimony is finally illustrated with the parametric reconstruction of the body size of cetaceans.

The aim of the present study is to compare the clinical efficacy and safety of two different vacuum-assisted closure (VAC) applications in one center between two groups of patients with Wagner Grade 3-4 multiple chronic diabetic foot wounds. The study was a randomized-controlled, prospective investigation between two groups of patients with Wagner Grade 3-4 multiple chronic diabetic foot wounds at single extremity. There were 10 patients in the first group receiving VAC treatment by means of Y-connector and 11 patients in the second group receiving bridge-VAC treatment. There were no significant difference in Revised Foot Function Index scores and total treatment costs between the both groups. The cost of the VAC dressing supplies in one session of the dressings was lower in the bridge-VAC group. In conclusion, although bridge-VAC treatment seems to be an alternative method to the VAC treatment by means of Y-connector, we found no superiority of one over the other VAC application for chronic diabetic foot wounds.

Extraction of high quality DNA from seized Moroccan cannabis resin (Hashish.

Directory of Open Access Journals (Sweden)

Moulay Abdelaziz El Alaoui

Full Text Available The extraction and purification of nucleic acids is the first step in most molecular biology analysis techniques. The objective of this work is to obtain highly purified nucleic acids derived from Cannabis sativa resin seizure in order to conduct a DNA typing method for the individualization of cannabis resin samples. To obtain highly purified nucleic acids from cannabis resin (Hashish free from contaminants that cause inhibition of PCR reaction, we have tested two protocols: the CTAB protocol of Wagner and a CTAB protocol described by Somma (2004 adapted for difficult matrix. We obtained high quality genomic DNA from 8 cannabis resin seizures using the adapted protocol. DNA extracted by the Wagner CTAB protocol failed to give polymerase chain reaction (PCR amplification of tetrahydrocannabinolic acid (THCA synthase coding gene. However, the extracted DNA by the second protocol permits amplification of THCA synthase coding gene using different sets of primers as assessed by PCR. We describe here for the first time the possibility of DNA extraction from (Hashish resin derived from Cannabis sativa. This allows the use of DNA molecular tests under special forensic circumstances.

Does Media Multitasking Always Hurt?

Directory of Open Access Journals (Sweden)

Lui Fai Hong

2011-05-01

Full Text Available Chronic heavy media multitaskers have been found impaired cognitive performance on certain cognitive tasks (Ophir, Nass & Wagner, 2009. However, the poor performance may be caused by their breadth-biased style of cognitive control rather than a deficit in cognitive abilities such as the ability to filter out interference from irrelevant stimuli and representations in memory. In this study, a new media multitasking index was invented to differentiate heavy and light media multitaskers by adding three open ended questions to the Media Use Questionnaire used by Ophir, Nass and Wagner (2009. Also, four different cognitive tasks, which access the ability of attentional capture, attention allocation to infrequent information, task switching and crossmodal integration, were used to investigate whether the poor performance of heavy media multitaskers is general to a wider range of tasks. Preliminary results found that heavy media multitaskers showed better improvement in accuracy between the sound present condition and sound absent condition of Pip and Pop Task (Van der Burg, Olivers, Bronkhorst, & theeuwes, 2008. Heavy media multitaskers appeared to have better ability of crossmodal integration than light medie multitaskers; hence, their poor performance is limited in only certain cognitive tasks.

Full Text Available Objective: Few studies have identified factors as predictors of clinical prognosis of patients with diabetic foot ulcers (DFUs, especially of Chinese patients. In this study, we assessed the prognostic factors of Chinese patients with DFUs. Methods and materials: This was a retrospective study (January 2009–January 2011 of 194 DFUs conducted in an inpatient population at PLA 454 Hospital in Nanjing, China, to determine the prognostic influential factors of DFUs in Chinese patients. All of the studied patients were grouped into an amputation group, a non-healing group, and a cured group, according to the clinical prognosis. Patient parameters, including gender, age, smoking habits, education level, family history of diabetes mellitus, medical history, duration of foot lesions and complications, ankle-brachial index (ABI, transcutaneous oxygen pressure (TcPO2, urinary albumin/creatinine ratio (Alb/Cr, fundus oculi, electrocardiogram, DFU characteristics, bacterial nature, and neuropathy, were cross-studied among the three groups. Results: Compared with the other two groups, the amputation group showed a higher number of males, older in age, lower ABI and TcPO2 levels, higher Wagner wound grading and size, and significantly higher urinary Alb/Cr ratio, blood urea nitrogen, serum creatinine, white blood cell count, and erythrocyte sedimentation rate. Compared to the cured group (162 patients, more patients with an older age, smoking, family history of diabetes mellitus, medical history of foot ulcerations, lower ABI and TcPO2 levels, higher urine Alb/Cr ratio, and serum creatinine were found in the non-healing group. Regression analysis was used to study the correlation between various factors and clinical prognosis, and the results were as follows: age, Wagner wound classification, and heel ulcerations were negatively correlated to the DFU prognosis, whereas the female population, ABI, and TcPO2 were positively correlated with DFU prognosis

A note on the effective medium theory of random resistive-reactive medium

International Nuclear Information System (INIS)

Kumar, N.; Jayannavar, A.M.

1981-06-01

The effective medium theory for a system with randomly distributed point conductivity and polarizability is re-formulated, with attention to cross-terms involving the two disorder parameters. The treatment reveals a certain inconsistency of the conventional theory owing to the neglect of the Maxwell-Wagner effect. The results are significant for the critical resistivity and dielectric anomalies of a binary liquid mixture at the phase-separation point. (author)

Macroscopic study of the digestive tract of Gracilinanus microtarsus (Wagner, 1842 (Mammalia: Didelphidae

Directory of Open Access Journals (Sweden)

Luis Miguel Lobo

2014-03-01

Full Text Available Gracilinanus microtarsus is a small marsupial species belonging to the Didelphidae family. It has an omnivorous/frugivorous feeding habit and, therefore, it has a great ecological importance, because it is a seed-dispersing species. This article aims to describe the macroscopic morphology of the digestive tract in G. microtarsus. We used 4 animals fixed in 10% formaldehyde. The organs were dissected, measured, and photographed. The animals under study had the dental formula 2x I 5/4 C 1/1 P 3/3 M 4/4. This is the dental formula of the whole Didelphidae family. The dorsum of the tongue had vallate, fungiform, and filiform papillae. Tubular esophagus evidenced the cervical, thoracic, and abdominal portions. The unicavitary stomach consisted of glandular and aglandular region and gastric folds. Small intestine had 3 portions: duodenum, jejunum, and ileum. Large intestine consisted of: cecum, colon, and rectum. Parotid salivary gland was the largest and it had a flattened shape. The sublingual salivary gland, whi h was the smallest, had a flattened and elongated shape. Mandibular salivary gland had an oval shape. Pancreas had a dispersed shape and lobulated aspect. Liver had a dome shape and it consisted of the lobes right medial, square, right side, left medial, left side, and caudate. The digestive tract of the animals under study is similar to the marsupial species described in the literature.

LDPE/HDPE/Clay Nanocomposites: Effects of Compatibilizer on the Structure and Dielectric Response

2013-01-01

Full Text Available PE/clay nanocomposites were prepared by mixing a commercially available premixed polyethylene/O-MMT masterbatch into a polyethylene blend matrix containing 80 wt% low-density polyethylene and 20 wt% high-density polyethylene with and without anhydride modified polyethylene (PE-MA as the compatibilizer using a corotating twin-screw extruder. In this study, the effect of nanoclay and compatibilizer on the structure and dielectric response of PE/clay nanocomposites has been investigated. The microstructure of PE/clay nanocomposites was characterized using wide-angle X-ray diffraction (WAXD and a scanning electron microscope (SEM. Thermal properties were examined using differential scanning calorimetry (DSC. The dielectric response of neat PE was compared with that of PE/clay nanocomposite with and without the compatibilizer. The XRD and SEM results showed that the PE/O-MMT nanocomposite with the PE-MA compatibilizer was better dispersed. In the nanocomposite materials, two relaxation modes are detected in the dielectric losses. The first relaxation is due to a Maxwell-Wagner-Sillars interfacial polarization, and the second relaxation can be related to dipolar polarization. A relationship between the degree of dispersion and the relaxation rate fmax of Maxwell-Wagner-Sillars was found and discussed.

A nodal expansion method using conformal mapping for hexagonal geometry

International Nuclear Information System (INIS)

Chao, Y.A.; Shatilla, Y.A.

1993-01-01

Hexagonal nodal methods adopting the same transverse integration process used for square nodal methods face the subtle theoretical problem that this process leads to highly singular nonphysical terms in the diffusion equation. Lawrence, in developing the DIF3D-N code, tried to approximate the singular terms with relatively simple polynomials. In the HEX-NOD code, Wagner ignored the singularities to simplify the diffusion equation and introduced compensating terms in the nodal equations to restore the nodal balance relation. More recently developed hexagonal nodal codes, such as HEXPE-DITE and the hexagonal version of PANTHER, used methods similar to Wagner's. It will be shown that for light water reactor applications, these two different approximations significantly degraded the accuracy of the respective method as compared to the established square nodal methods. Alternatively, the method of conformal mapping was suggested to map a hexagon to a rectangle, with the unique feature of leaving the diffusion operator invariant, thereby fundamentally resolving the problems associated with transverse integration. This method is now implemented in the Westinghouse hexagonal nodal code ANC-H. In this paper we report on the results of comparing the three methods for a variety of problems via benchmarking against the fine-mesh finite difference code

Os comunistas conselhistas e o anarquismo: a crítica ao anarco-sindicalismo no contexto da guerra civil espanhola

Este texto tem como principal objetivo demonstrar como o marxismo, principalmente os comunistas conselhistas, abordaram historicamente o anarquismo. O anarquismo é prenhe de várias tendências: anarco-coletivismo, anarco-individualismo, anarco-mutualismo, anarco-sindicalismo etc. A tendência que destacaremos neste artigo é o anarco-sindicalismo, visto ter sido esta a que os comunistas de conselhos mais criticaram. O Comunismo de Conselhos se desenvolve a partir da segunda metade da década de 1920. Tem em autores como Helmut Wagner, Anton Pannekoek, Karl Korsch, Herman Gorter, Paul Mattick etc. seus principais expoentes. Os autores conselhistas aqui analisados são Wagner e Mattick, pois foram os únicos a polemizarem diretamente com os anarco-sindicalistas no processo da Guerra Civil Espanhola de 1936 a 1939.  Da crítica destes autores ao anarco-sindicalismo conclui-se: que o anarco-sindicalismo e burocrático; que representa uma perspectiva contrária aos trabalhadores; que deve, portanto, ser combatido e não reforçado.

Revised Chapman-Enskog analysis for a class of forcing schemes in the lattice Boltzmann method.

Science.gov (United States)

Li, Q; Zhou, P; Yan, H J

2016-10-01

In the lattice Boltzmann (LB) method, the forcing scheme, which is used to incorporate an external or internal force into the LB equation, plays an important role. It determines whether the force of the system is correctly implemented in an LB model and affects the numerical accuracy. In this paper we aim to clarify a critical issue about the Chapman-Enskog analysis for a class of forcing schemes in the LB method in which the velocity in the equilibrium density distribution function is given by u=∑_{α}e_{α}f_{α}/ρ, while the actual fluid velocity is defined as u[over ̂]=u+δ_{t}F/(2ρ). It is shown that the usual Chapman-Enskog analysis for this class of forcing schemes should be revised so as to derive the actual macroscopic equations recovered from these forcing schemes. Three forcing schemes belonging to the above class are analyzed, among which Wagner's forcing scheme [A. J. Wagner, Phys. Rev. E 74, 056703 (2006)10.1103/PhysRevE.74.056703] is shown to be capable of reproducing the correct macroscopic equations. The theoretical analyses are examined and demonstrated with two numerical tests, including the simulation of Womersley flow and the modeling of flat and circular interfaces by the pseudopotential multiphase LB model.

The Klamath Mountains Ecoregion covers approximately 47,791 km2 (18,452 mi2) of the Klamath and Siskiyou Mountains of northern California and southern Oregon (fig. 1) (Omernik, 1987; U.S. Environmental Protection Agency, 1997). The ecoregion is flanked by the Coast Range Ecoregion to the west, the Southern and Central California Chaparral and Oak Woodlands Ecoregion to the south, the Cascades and the Eastern Cascades Slopes and Foothills Ecoregions to the east, and the Willamette Valley Ecoregion to the north. The mild Mediterranean climate of the ecoregion is characterized by hot, dry summers and wet winters; the amount of winter moisture varies within the ecoregion, decreasing from west to east. The Klamath–Siskiyou Mountains region is widely recognized as an important biodiversity hotspot (Whittaker, 1960; Kruckeberg, 1984; Wagner, 1997; DellaSala and others, 1999), containing more than 3,500 plant species, more than 200 of which are endemic (Sawyer, 2007). A biological assessment by DellaSala and others (1999) ranked the Klamath–Siskiyou Mountains region as the fifth richest coniferous forest in terms of species diversity. In addition, the International Union for the Conservation of Nature considers the region an area of notable botanical importance (Wagner, 1997). Twenty-nine different species of conifers can be found in the Klamath Mountains Ecoregion (Sawyer, 1996).

Full Text Available Effects of a topical cream containing P. amboinicus (Lour. Spreng. (Lamiaceae and C. asiatica (L. Urban (Umbelliferae were evaluated and compared to effects of hydrocolloid fiber wound dressing for diabetic foot ulcers. A single-center, randomized, controlled, open-label study was conducted. Twenty-four type 1 or type 2 diabetes patients aged 20 years or older with Wagner grade 3 foot ulcers postsurgical debridement were enrolled between October 2008 and December 2009. Twelve randomly assigned patients were treated with WH-1 cream containing P. amboinicus and C. asiatica twice daily for two weeks. Another 12 patients were treated with hydrocolloid fiber dressings changed at 7 days or when clinically indicated. Wound condition and safety were assessed at days 7 and 14 and results were compared between groups. No statistically significant differences were seen in percent changes in wound size at 7- and 14-day assessments of WH-1 cream and hydrocolloid dressing groups. A slightly higher proportion of patients in the WH-1 cream group (10 of 12; 90.9% showed Wagner grade improvement compared to the hydrocolloid fiber dressing group but without statistical significance. For treating diabetic foot ulcers, P. amboinicus and C. asiatica cream is a safe alternative to hydrocolloid fiber dressing without significant difference in effectiveness.

Full Text Available In this work, the viscous and viscoelastic responses of food emulsions stabilized by proteins are studied. The damping function determined from the relaxation modulus, together with the relaxation spectrum calculated from the dynamic modulus, allowed a prediction of the material response under steady-state conditions by applying the Wagner model. On the other hand, the study of the evolution of the microstructure of these systems under shear allows to explain the behavior observed in steady-flow tests, as well as the lack of concordance between experimental an predicted values.

En este trabajo se estudian las respuestas viscosa y viscoelástica de emulsiones alimentarias estabilizadas por proteínas. La función de amortiguación determinada desde el módulo de relajación ha permitido, junto con el espectro de relajación calculado a partir de los módulos dinámicos, predecir la respuesta del material en condiciones de cizalla estacionaria mediante la aplicación del modelo de Wagner. Por otra parte, el estudio de la evolución de la microestructura de estos sistemas con la cizalla permite explicar el comportamiento observado en ensayos de flujo estacionario, así como la falta de concordancia entre los resultados experimentales y los predichos.

Error Characterisation and Merging of Active and Passive Microwave Soil Moisture Data Sets

Science.gov (United States)

Wagner, Wolfgang; Gruber, Alexander; de Jeu, Richard; Parinussa, Robert; Chung, Daniel; Dorigo, Wouter; Reimer, Christoph; Kidd, Richard

2015-04-01

As part of the Climate Change Initiative (CCI) programme of the European Space Agency (ESA) a data fusion system has been developed which is capable of ingesting surface soil moisture data derived from active and passive microwave sensors (ASCAT, AMSR-E, etc.) flown on different satellite platforms and merging them to create long and consistent time series of soil moisture suitable for use in climate change studies. The so-created soil moisture data records (latest version: ESA CCI SM v02.1 released on 5/12/2014) are freely available and can be obtained from http://www.esa-soilmoisture-cci.org/. As described by Wagner et al. (2012) the principle steps of the data fusion process are: 1) error characterisation, 2) matching to account for data set specific biases, and 3) merging. In this presentation we present the current data fusion process and discuss how new error characterisation methods, such as the increasingly popular triple collocation method as discussed for example by Zwieback et al. (2012) may be used to improve it. The main benefit of an improved error characterisation would be a more reliable identification of the best performing microwave soil moisture retrieval(s) for each grid point and each point in time. In case that two or more satellite data sets provides useful information, the estimated errors can be used to define the weights with which each satellite data set are merged, i.e. the lower its error the higher its weight. This is expected to bring a significant improvement over the current data fusion scheme which is not yet based on quantitative estimates of the retrieval errors but on a proxy measure, namely the vegetation optical depth (Dorigo et al., 2015): over areas with low vegetation passive soil moisture retrievals are used, while over areas with moderate vegetation density active retrievals are used. In transition areas, where both products correlate well, both products are being used in a synergistic way: on time steps where only one of

Hide and vanish: data sets where the most parsimonious tree is known but hard to find, and their implications for tree search methods.

Science.gov (United States)

Goloboff, Pablo A

2014-10-01

Three different types of data sets, for which the uniquely most parsimonious tree can be known exactly but is hard to find with heuristic tree search methods, are studied. Tree searches are complicated more by the shape of the tree landscape (i.e. the distribution of homoplasy on different trees) than by the sheer abundance of homoplasy or character conflict. Data sets of Type 1 are those constructed by Radel et al. (2013). Data sets of Type 2 present a very rugged landscape, with narrow peaks and valleys, but relatively low amounts of homoplasy. For such a tree landscape, subjecting the trees to TBR and saving suboptimal trees produces much better results when the sequence of clipping for the tree branches is randomized instead of fixed. An unexpected finding for data sets of Types 1 and 2 is that starting a search from a random tree instead of a random addition sequence Wagner tree may increase the probability that the search finds the most parsimonious tree; a small artificial example where these probabilities can be calculated exactly is presented. Data sets of Type 3, the most difficult data sets studied here, comprise only congruent characters, and a single island with only one most parsimonious tree. Even if there is a single island, missing entries create a very flat landscape which is difficult to traverse with tree search algorithms because the number of equally parsimonious trees that need to be saved and swapped to effectively move around the plateaus is too large. Minor modifications of the parameters of tree drifting, ratchet, and sectorial searches allow travelling around these plateaus much more efficiently than saving and swapping large numbers of equally parsimonious trees with TBR. For these data sets, two new related criteria for selecting taxon addition sequences in Wagner trees (the "selected" and "informative" addition sequences) produce much better results than the standard random or closest addition sequences. These new methods for Wagner

The importance of such a system is due to its potential application as a pH-controlled drug carrier. Our preliminary experimental studies showed that fabrication of such a nanobottle/nanocontainer is feasible and it is possible to encapsulate the anticancer drug cisplatin inside the inner space of a CNT and seal its ends by functionalized AuNPs. The expected behavior, that is, detachment of AuNPs at acidic pH and the release of cisplatin, was, however, not observed. On the other hand, our theoretical studies of chemically identical system led to the conclusion that the release of cisplatin at acidic pH should be observed. Therefore, in this work, a deeper theoretical analysis of various factors that could be responsible for the disagreement between experimental and theoretical results were performed. The study found that the major factor is a large dispersion interaction component acting between CNT and AuNP in solution in the case of the experimental system. This factor can be controlled to some extent by tuning the system size or the ratio between AuNP diameter and CNT diameter. Thus, such kind of a pH-sensitive drug carrier is still of great interest, but its structural parameters need to be properly adjusted. Keywords: hydrazone bond, drug delivery, dispersion interactions, cisplatin, acidic pH

In this study, the dielectric properties of metal-oxide-metal capacitors based on Tantalum Titanium Oxide (TiTaO) thin films deposited by reactive magnetron sputtering on aluminum bottom electrode are investigated. The structure of the films was characterized by Atomic Force Microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The dielectric properties of TiTaO thin films were studied by complex impedance spectroscopy over a wide frequency range (10{sup -2} - to 10{sup 5} Hz) and temperatures in -50 °C to 325 °C range. The contributions of different phases, phases’ boundaries and conductivity effect were highlighted by Cole – Cole diagram (ε” versus ε’). Two relaxation processes have been identified in the electric modulus plot. A first relaxation process appears at low temperature with activation energy of 0.37 eV and it is related to the motion of Ti{sup 4+} (Skanavi’s model). A second relaxation process at high temperature is related to Maxwell-Wagner-Sillars relaxation with activation energy of 0.41 eV. - Highlights: • Titanium Tantalum Oxide thin films are grown on Aluminum substrate. • The existence of phases was confirmed by X-ray photoelectron spectroscopy. • Conductivity effect appears in Cole-Cole plot. • At low temperatures, a relaxation phenomenon obeys to Skanavi’s model. • Maxwell-Wagner-Sillars polarization is processed at high temperatures.

The rearrangement pathways of the equilibrating tertiary carbocations, 2,3-dimethyl-2-butyl cation (C6H13(+), 1), 2,3,3-trimethyl-2-butyl cation (C7H15(+), 5) and 2,3-dimethyl-2-pentyl cation (C7H15(+), 8 and 9) were investigated using the ab initio/GIAO-CCSD(T) (13)C NMR method. Comparing the calculated and experimental (13)C NMR chemical shifts of a series of carbocations indicates that excellent prediction of δ(13)C could be achieved through scaling. In the case of symmetrical equilibrating cations (1 and 5) the Wagner-Meerwein 1,2-hydride and 1,2-methide shifts, respectively, produce the same structure. This indicates that the overall (13)C NMR chemical shifts are conserved and independent of temperature. However, in the case of unsymmetrical equilibrating cations (8 and 9) the Wagner-Meerwein shift produces different tertiary structures, which have slightly different thermodynamic stabilities and, thus, different spectra. At the MP4(SDTQ)/cc-pVTZ//MP2/cc-pVTZ + ZPE level structure 8 is only 90 calories/mol more stable than structure 9. Based on computed (13)C NMR chemical shift calculations, mole fractions of these isomers were determined by assuming the observed chemical shifts are due to the weighted average of the chemical shifts of the static ions. © 2015 Wiley Periodicals, Inc.

Thermodynamic analysis of high-temperature regenerative organic Rankine cycles using siloxanes as working fluids

Fernandez, F.J.; Prieto, M.M.; Suarez, I.

2011-01-01

A recent novel adjustment of the Span-Wagner equation of state for siloxanes, used as working fluids in high-temperature organic Rankine cycles, is applied in a mathematical model to solve cycles under several working conditions. The proposed scheme includes a thermo-oil intermediate heat circuit between the heat source and the organic Rankine cycle. Linear and cyclic siloxanes are assayed in saturated, superheated and supercritical cycles. The cycle includes an internal heat exchanger (regenerative cycle), although a non-regenerative scheme is also solved. In the first part of the study, a current of combustion gases cooled to close to their dew point temperature is taken as the reference heat source. In the second part, the outlet temperature of the heat source is varied over a wide range, determining appropriate fluids and schemes for each thermal level. Simple linear (MM, MDM) siloxanes in saturated regenerative schemes show good efficiencies and ensure thermal stability of the working fluid. -- Highlights: → Organic Rankine cycles with polymethylsiloxanes as working fluids were modelled. → The cycle scheme is regenerative and includes an intermediate heat transfer fluid. → The fluid properties were calculated by means of the Span-Wagner equation of state. → Vapour conditions to the expander and source thermal level were analysed. → Siloxanes MM, MDM and D 4 under saturated conditions were the best options.

We assessed potential racial or ethnic differences in the degree to which veterans with pharmaceutically treated hypertension report experiences with their primary care system that are consistent with optimal chronic illness care as suggested by Wagner's Chronic Care Model (CCM). A cross-sectional analysis of the results of the Patient Assessment of Chronic Illness Care (PACIC), which measured components of the care system suggested by the CCM and was completed at baseline by participants in a hypertension disease management clinical trial. Participants had a recent history of uncontrolled systolic blood pressure. Among 377 patients, non-Hispanic African American veterans had almost twice the odds of indicating that their primary care experience is consistent with CCM features when compared with non-Hispanic White patients (odds ratio (OR) = 1.86; 95% confidence interval (CI) = 1.16-2.98). Similar statistically significant associations were observed for follow-up care (OR = 2.59; 95% CI = 1.49-4.50), patient activation (OR = 1.80; 95% CI = 1.13-2.87), goal setting (OR = 1.65; 95% CI = 1.03-2.64), and help with problem solving (OR = 1.62; 95% CI = 1.00-2.60). Non-Hispanic African Americans with pharmaceutically treated hypertension report that the primary care system more closely approximates the Wagner CCM than non-Hispanic White patients.

To determine the outcome of diabetic neuropathic foot ulcers treated with Total Contact Cast (TCC) in terms of percentage of ulcers healed and time to heal. The study included diabetic patients with non-ischemic neuropathic foot ulcers of upto grade 2 of Wagner's classification. Ulcers were debrided off necrotic tissues and Total Contact Cast (TCC) was applied. TCC was renewed every 2 weeks till healing. Cases were labeled as cast failure when there was no reduction in wound size in 4 consecutive weeks or worsening to a higher grade. Main outcome measures were the percentage of ulcers healed and time to heal in the cast. Thirty four (87.17%) patients were males and 5(12.82%) were females. The mean age was 62 +- 13.05 years. All patients had NIDDM. Out of the 52 ulcers, 41(78.84%) healed with TCC in an average 2 casts duration (mean 32 days). There were 11(21.15%) cast failure. Majority (63.63%) of cast failure ulcers were located on pressure bearing area of heel. Most (90%) of the ulcers on forefoot and midsole region healed with TCC (p<0.001). Longer ulcer duration (mean 57.45 +- 29.64 days) significantly reduced ulcer healing (p<0.001). Total contact cast was an effective treatment modality for neuropathic diabetic foot ulcers of Wagner's grade 2, located on forefoot and midsole region. (author)

A model for simulating the transient behavior of solid electrodes undergoing deposition or dissolution has been developed. The model accounts for ohmic drop, charge transfer overpotential, and mass transport limitations. The finite difference method, coupled with successive overrelaxation, was used as the basis of the solution technique. An algorithm was devised to overcome the computational instabilities associated with the calculations of the secondary and tertiary current distributions. Simulations were performed on several model electrode profiles: the sinusoid, the rounded corner, and the notch. Quantitative copper deposition data were obtained in a contoured rotating cylinder system, Sinusoidal cross-sections, machined on stainless steel cylinders, were used as model geometries, Kinetic parameters for use in the simulation were determined from polarization curves obtained on copper rotating cylinders, These parameters, along with other physical property and geometric data, were incorporated in simulations of growing sinusoidal profiles. The copper distributions on the sinusoidal cross-sections were measured and found to compare favorably with the simulated results. At low Wagner numbers the formation of a slight depression at the profile peak was predicted by the simulation and observed on the profile. At higher Wagner numbers, the simulated and experimental results showed that the formation of a depression was suppressed. This phenomenon was shown to result from the competition between ohmic drop and electrode curvature.

Full Text Available The magnetocapacitance effects of MnZn ferrites with different initial permeabilities have been studied systematically. Both intrinsic effect associated with magnetoelectric coupling and extrinsic effect, which means the combined contribution of magnetoresistance and the Maxwell-Wagner effect, have been observed simultaneously. Analysis shows that the relationship between the origins of both is in competitive equilibrium. Either of both mechanisms plays a dominant role in magnetocapacitance effects under different conditions, respectively, such as permeability and frequency of applied signals.

Development of a New Research Data Infrastructure for Collaboration in Earth Observation and Global Change Science

Science.gov (United States)

Wagner, Wolfgang; Briese, Christian

2017-04-01

With the global population having surpassed 7 billion people in 2012, the impacts of human activities on the environment have started to be noticeable almost everywhere on our planet. Yet, while pressing social problems such as mass migration may be at least be partly a consequence of these impacts, many are still elusive, particularly when trying to quantify them on larger scales. Therefore, it is essential to collect verifiable observations that allow tracing environmental changes from a local to global scale over several decades. Complementing in situ networks, this task is increasingly fulfilled by earth observation satellites which have been acquiring measurements of the land, atmosphere and oceans since the beginning of the 1970s. While many multi-decadal data sets are already available, the major limitation hindering their effective exploitation in global change studies is the lack of dedicated data centres offering the high performance processing capabilities needed to process multi-year global data sets at a fine spatial resolution (Wagner, 2015). Essentially the only platform which currently offers these capabilities is Google's Earth Engine. From a scientific perspective there is undoubtedly a high need to build up independent science-driven platforms that are transparent for their users and offer a higher diversity and flexibility in terms of the data sets and algorithms used. Recognizing this need, TU Wien founded the EODC Earth Observation Data Centre for Water Resources Monitoring together with other Austrian partners in May 2014 as a public-private partnership (Wagner et al. 2014). Thanks to its integrative governance approach, EODC has succeeded of quickly developing an international cooperation consisting of scientific institutions, public organisations and several private partners. Making best use of their existing infrastructures, the EODC partners have already created the first elements of a federated IT infrastructure capable of storing and

Full Text Available PURPOSE OF STUDY: Diabetic foot is the most common complication of diabetes. Amputation which is the end result of diabetic foot disease is associated with significant morbidity and mortality. Since it is crucial to identify those at an increased risk of diabetic foot complications, a detailed study of the natural history of diabetic foot, various clinical characteristics, according to Wagner grading of lesions, their outcome and management protocol followed in our hospital was undertaken in our hospital. AIM AND OBJECTIVE: Evaluation of diabetic foot lesions based on Wagner grading system, outcome and management protocol followed in our hospital. MATERIALS AND METHODS: A prospective study done on hundred diabetic foot patients in our own hospital over a period of one and half year. Data was obtained from a questionnaire developed to record the medical history, examination details, investigations reports, treatment details and final outcome at the end of stay. Infection was classified based on Meggitt-Wagner, classification/grading. RESULTS: Diabetic foot was very common in elderly age group (>55yrs 54% and male dominant (87%. Majority of them had diabetes for more than five years (47% and complications of diabetes were present on admission in 15% of them. Grade I(29%, Grade III (27% & Grade IV (24% lesions based on Wagner’s grading accounted for majority of diabetic foot lesions. Multiple toe disarticulation/ above knee / below knee amputation accounted for a quarter (23% of surgical interventions in our hospital. The glycemic control in most of patients was very poor with RBS>200 mg/dl (70% and glycosylated hemoglobin>7g% (74% of them. A quarter of the patients stayed for at least a month in the hospital (25%. CONCLUSION: It can be concluded that diabetic foot in various forms accounts for significant morbidity in the surgical wards.

2016-01-01

The Institute of Materials Science and Engineering (Institut für Werkstoffwissenschaft und Werkstofftechnik, IWW) is a well-established part of the Faculty of Mechanical Engineering at Technische Universität Chemnitz, Germany. We are proud to host our traditional scientific meeting, the Chemnitz Seminar on Materials Engineering - Werkstofftechnisches Kolloquium, this year being the 18 th Seminar. The aim of our meeting is to bring together scientists and engineers both from academia and industry, and this is reflected by the different scientific sessions that cover various relevant topics, such as composite materials, microstructural analysis, and surface engineering. Special focus sessions highlight recent developments in the Federal Cluster of Excellence MERGE and in the Collaborative Research Center SFB 692, both established in Chemnitz. We, as organizers, continuously strive to improve our Seminar, and we therefore decided to provide all contributors with the opportunity to publish their papers, in addition to the printed Proceedings volume, in an international, peer-reviewed journal. Publication in IOP Conference Series: Materials Science and Engineering allows for a wide dissemination of the many interesting and relevant results presented in our Seminar. Clearly, this is understood and appreciated by many participants of our meeting: more than 65% of all authors chose to also publish their Proceedings papers in this special issue, which consequently provides an excellent overview of the main topics of our Seminar.

Full Text Available Mutually beneficial co-existence of the private and state sectors can be seen as proven in theory. The proof is the concept of a two-sector economy of A. Wagner (1835–1917, while, in Wagner’s view, the importance of the state sector should grow (Wagner’s law. State finance is understood in this context as a tool used to achieve social justice, and in general as a socially stabilizing element.In conditions of real Czech economy, the relationship between the state and private sectors is shown in the form of subsidies for businesses enterprises; although at first sight the available data do not demonstrate the key role of public finance. Another form of limited understanding of the importance of public funds is the concept of financial structure of a company understood by contemporary theory of finance of firm (in Czech context as a set of sources for financing entrepreneurial activities – public funds are virtually not mentioned here.The aim of the paper is to contribute to correct this shift in understanding of the importance of public finance and to bring it nearer both to the original theoretical concept (A. Wagner and to reality, both in quantitative and qualitative terms.Main focus of this paper is to the Czech Republic circumstances. For the comparison are here presented available data from other countries and global data as well.

Highlights: • Vapor pressures of three pure apple aroma constituents were measured. • Measurements were made over the temperature range of (362.1 to 429.9) K. • Constants of Antoine and Wagner type equations were fitted to the experimental data. • Relative deviations (rmsd) from the three vapor-pressure equations were <0.9%. • Contrast with literature showed discrepancies <9% among them and with this work. - Abstract: The saturated vapor pressures of pure ethyl-2-methylbutyrate, hexanal and (E)-2-hexenal, which are volatile compounds characteristic of apple aroma, were measured with a dynamic recirculation apparatus at a pressure range of (24.5 to 190.0) kPa. Measurements were made over the temperature range of (362.1 to 429.9) K for ethyl-2-methylbutyrate, (358.1 to 425.8) K for hexanal, and (373.5 to 446.2) K for (E)-2-hexenal. The maximum likelihood method was used to estimate the parameters of the Antoine equation, whereas the parameters of an extended Antoine equation and the Wagner equation were determined by non linear least square method. The three models showed root mean square deviations (rmsd) of 0.29%, 0.28%, and 0.27% for ethyl-2-methylbutyrate, 0.58%, 0.48%, and 0.38% for hexanal, and 0.89%, 0.62% and 0.36% for (E)-2-hexenal, respectively. Additionally, the experimental data and correlation were compared with those available in the literature

The orthobaric density of liquid NH 3 has been measured from about 200 to 287 K, and for liquid ND 3 from about 205 to 273 K. The molar volume of liquid NH 3 exceeds that of ND 3 by between 0.8 and 0.9 per cent. The difference of the vapour pressures of the two compounds has been measured from about 200 to 266 K, and the vapour pressure of NH 3 from the triple-point temperature to 234 K. Liquid NH 3 has the higher vapour pressure, the difference being relatively large for a pair of isotopic compounds. At 200 K, the ratio of the vapour pressure of NH 3 to that of ND 3 is about 1.2. The available vapour pressures for NH 3 have been fitted to a Wagner equation. By combining vapour pressures derived from this equation with the differential measurements, values for the vapour pressure of ND 3 have been obtained. These values have likewise been fitted to a Wagner equation. The material presented in this paper has been used to estimate the molar enthalpies of vaporization of NH 3 (l) and of ND 3 (l) from the triple-point temperatures to 290 K. The molar enthalpy of vaporization of ND 3 exceeds that of NH 3 throughout this range. The difference amounts to about 3.5 per cent at the triple-point temperatures, and decreases with rising temperature. (author)

Evaluation of automatic vacuum- assisted compaction solutions

2011-01-01

Full Text Available Currently on the mould-making machines market the companies like: DiSA, KUENKEL WAGNER, HAFLINGER, HEINRICH WAGNER SINTO, HUNTER, SAVELLI AND TECHNICAL play significant role. These companies are the manufacturers of various solutions in machines and instalations applied in foundry engineering. Automatic foundry machines for compaction of green sand have the major role in mechanisation and automation processes of making the mould. The concept of operation of automatic machines is based on the static and dynamic methods of compacting the green sand. The method which gains the importance is the compacting method by using the energy of the air pressure. It's the initial stage or the supporting process of compacting the green sand. However in the automatic mould making machines using this method it's essential to use the additional compaction of the mass in order to receive the final parameters of the form. In the constructional solutions of the machines there is the additional division which concerns the method of putting the sand into the mould box. This division distinquishes the transport of the sand with simultaneous compaction or the putting of the sand without the pre-compaction. As the solutions of the major manufacturers are often the subject for application in various foundries, the authors of the paper would like/have the confidence to present their own evaluation process confirmed by their own researches and independent analysis of the producers' solutions.

Highlights: • Quasi-static permittivity of potassium polytitanates compacts achieves 10 4 –10 5 . • Observed Maxwell–Wagner polarization attributes to layered structure of polytitanates. • The conductivity varies from 5 × 10 −2 to 10 −6 –10 −7 Sm/m in a wide range of temperatures. - Abstract: Titanates of alkali metals are widely applied materials as they are relatively low in cost and might be easily synthesized. They are utilized as adsorbents, catalysts, solid state electrolytes, superconductors. Here we report our results on electrical properties of the compacted amorphous potassium polytitanates powders. The electrical properties of the compacts were studied by means of complex impedance spectroscopy in a wide range of frequencies at different temperatures using two-electrode configuration. The frequency dependences of conductivity for the investigated potassium polytitanates compacts varies in the range from 5 × 10 −2 Sm/m (high frequencies, ion conductivity) up to 10 −6 –10 −7 Sm/m (low frequencies, electron conductivity) for a wide range of temperatures (19–150 °C). According to the results, at low frequencies quasi-static permittivity of the stabilized PPT compacts achieves high values of 10 4 –10 5 . This might be explained by Maxwell–Wagner polarization attributed to the layered structure of the potassium polytitanates particles containing potassium and hydronium ions together with crystallization water in the interlayer and is very promising for solid state electrolyte applications for moderate temperatures

Influence of prosthesis design and implantation technique on implant stresses after cementless revision THR

Duda Georg N

2011-05-01

Full Text Available Abstract Background Femoral offset influences the forces at the hip and the implant stresses after revision THR. For extended bone defects, these forces may cause considerable bending moments within the implant, possibly leading to implant failure. This study investigates the influences of femoral anteversion and offset on stresses in the Wagner SL revision stem implant under varying extents of bone defect conditions. Methods Wagner SL revision stems with standard (34 mm and increased offset (44 mm were virtually implanted in a model femur with bone defects of variable extent (Paprosky I to IIIb. Variations in surgical technique were simulated by implanting the stems each at 4° or 14° of anteversion. Muscle and joint contact forces were applied to the reconstruction and implant stresses were determined using finite element analyses. Results Whilst increasing the implant's offset by 10 mm led to increased implant stresses (16.7% in peak tensile stresses, altering anteversion played a lesser role (5%. Generally, larger stresses were observed with reduced bone support: implant stresses increased by as much as 59% for a type IIIb defect. With increased offset, the maximum tensile stress was 225 MPa. Conclusion Although increased stresses were observed within the stem with larger offset and increased anteversion, these findings indicate that restoration of offset, key to restoring joint function, is unlikely to result in excessive implant stresses under routine activities if appropriate fixation can be achieved.

Full Text Available Abstract Hsp90 reveals phenotypic variation in the laboratory, but is Hsp90 depletion important in the wild? Recent work from Chen and Wagner in BMC Evolutionary Biology has discovered a naturally occurring Drosophila allele that downregulates Hsp90, creating sensitivity to cryptic genetic variation. Laboratory studies suggest that the exact magnitude of Hsp90 downregulation is important. Extreme Hsp90 depletion might reactivate transposable elements and/or induce aneuploidy, in addition to revealing cryptic genetic variation.

Today, reliable software systems are the basis of any business or company. The continuous further development of those systems is the central component in software evolution. It requires a huge amount of time- man power- as well as financial resources. The challenges are size, seniority and heterogeneity of those software systems. Christian Wagner addresses software evolution: the inherent problems and uncertainties in the process. He presents a model-driven method which leads to a synchronization between source code and design. As a result the model layer will be the central part in further e

We study in d space-dimensions the finite temperature behavior of long range Neel order (LRNO) in CP N-1 model as a low energy effective field theory of the antiferromagnetic Heisenberg model. For d≤1, or d≤2 at any nonzero temperature, LRNO disappears, in agreement with Mermin-Wagner-Coleman's theorem. For d=3 in the weak coupling region, LRNO exists below the critical temperature T N (Neel temperature). T N decreases as the interlayer coupling becomes relatively weak compared with that within Cu-O layers. (author)

Intermetallic compounds of metals with non-metals such as C, N, and B show different hardness. Wagner's interaction parameter characterizes manner and extent of the interaction between the atoms of the substance dissolved and the additional elements in metallic mixed phases. An attempt has been made to correlate the hardness of carbides, nitrides, and borides (data taken from literature) with certain interaction parameters and associated thermodynamic quantities (ΔH, ΔG). For some metals of periods 4, 5, and 6 corresponding relations were found between microhardness, interaction parameters, heat of formation, and atomic number

Statistical thermodynamics -- A tool for understanding point defects in intermetallic compounds

International Nuclear Information System (INIS)

Ipser, H.; Krachler, R.

1996-01-01

The principles of the derivation of statistical-thermodynamic models to interpret the compositional variation of thermodynamic properties in non-stoichiometric intermetallic compounds are discussed. Two types of models are distinguished: the Bragg-Williams type, where the total energy of the crystal is taken as the sum of the interaction energies of all nearest-neighbor pairs of atoms, and the Wagner-Schottky type, where the internal energy, the volume, and the vibrational entropy of the crystal are assumed to be linear functions of the numbers of atoms or vacancies on the different sublattices. A Wagner-Schottky type model is used for the description of two examples with different crystal structures: for β'-FeAl (with B2-structure) defect concentrations and their variation with composition are derived from the results of measurements of the aluminum vapor pressure, the resulting values are compared with results of other independent experimental methods; for Rh 3 Te 4 (with an NiAs-derivative structure) the defect mechanism responsible for non-stoichiometry is worked out by application of a theoretical model to the results of tellurium vapor pressure measurements. In addition it is shown that the shape of the activity curve indicates a certain sequence of superstructures. In principle, there are no limitations to the application of statistical thermodynamics to experimental thermodynamic data as long as these are available with sufficient accuracy, and as long as it is ensured that the distribution of the point defects is truly random, i.e. that there are no aggregates of defects

Commercial samples of Magnetite with size ranging from 25–30 nm were coated with polyaniline by using radio frequency plasma polymerization to achieve a core shell structure of magnetic nanoparticle (core)–Polyaniline (shell). High resolution transmission electron microscopy images confirm the core shell architecture of polyaniline coated iron oxide. The dielectric properties of the material were studied before and after plasma treatment. The polymer coated magnetite particles exhibited a large dielectric permittivity with respect to uncoated samples. The dielectric behavior was modeled using a Maxwell–Wagner capacitor model. A plausible mechanism for the enhancement of dielectric permittivity is proposed.

2013-05-12

This paper concerns the displacement potential formulation of the post-impact influence of an air-cushioning layer on the 2D impact of a liquid half-space by a rigid body. The liquid and air are both ideal and incompressible and attention is focussed on cases when the density ratio between the air and liquid is small. In particular, the correction to classical Wagner theory is analysed in detail for the impact of circular cylinders and wedges. © The Authors 2013.

2012-09-19

This paper extends Wagner theory for the ideal, incompressible normal impact of rigid bodies that are nearly parallel to the surface of a liquid half-space. The impactors considered are three-dimensional and have an oblique impact velocity. A formulation in terms of the displacement potential is used to reveal the relationship between the oblique and corresponding normal impact solutions. In the case of axisymmetric impactors, several geometries are considered in which singularities develop in the boundary of the effective wetted region. We present the corresponding pressure profiles and models for the splash sheets. © 2012 Cambridge University Press.

Segmented polycarbonatediol polyurethane (PUPH) has been synthesized and modified with different amounts of graphite conductive filler (from 0 to 50 wt%). Thermal and dynamical thermal analysis of the composites clearly indicates changes in the polyurethane relaxations upon addition of graphite. Broadband dielectric spectroscopy has been used to study the dielectric properties of the (PUPH) and one composite in the frequency range from 10-2 to 107 Hz and in the temperature window of -140 to 170 °C. Relaxation processes associated with different molecular motions and conductivity phenomena (Maxwell-Wagner-Sillars and electrode polarization) are discussed and related to the graphite content.

This work shows the analysis of the effect on growth kinetics of gamma prima phase in Inconel 713C alloy of two thermic treatments. In this study, SEM are used and the results are analyzed by means of the theory developed by Lifshitz, Slyozov and Wagner (LSW theory). The findings have revealed that with such theory it is not possible to determine if the process of growth is controlled either through diffusion or through diffusion in the interface as to the time employed in the experiment (2600 hours); the time required is approximately 10000 hours.

1991-01-01

Fission track dating was applied in order to study obsidian samples originated from Mullumica and Callejones flows, Oyacachi, Ecuador. Preliminary data show that the ratio between the mean diameter os spontaneous and induced tracks is about 0.9, an indication that the analysed samples were submitted to small fading during their geological histories. Ages were obtained around 0.2 x 10 6 a, in agreement with Miller and Wagners's results. Ages ranging from 0.17 x 10 6 a up to 0.23 x 10 6 a were obtained correcting the apparent ages by means of the plateau method. (author)

The Modified Hummers method has been used to synthesize Graphene oxide nanoparticles. Microstructural analyses were carried out by X-ray diffraction and Fourier transform infrared spectroscopy. Optical properties were studied by UV-visible spectroscopy in the range of 200-700 nm. The energy band gap was calculated with the help of Tauc relation. The frequency dependence of dielectric constant and dielectric loss were studied over a range of the frequency 75Hz to 5MHz at room temperature. The dispersion in dielectric constant can be explained with the help of Maxwell-Wagner model in studied nanoparticles.

Crisis and Correspondence: Style in the Nineteenth Century

Directory of Open Access Journals (Sweden)

Mari Hvattum

2013-10-01

Full Text Available In his manifesto 'Das Kunstwerk der Zukunft' (1850, Richard Wagner characterised the nineteenth century as a time of crisis. Echoing Saint-Simon, he defined this crisis as a discrepancy between the spirit of the age and the actual, historical conditions. Evoking some of the most potent concepts of modern thinking—Zeitgeist, genius, and the Gesamtkunstwerk—Wagner outlined an aesthetic theory by which the artwork (including architecture simultaneously reflects and shapes its context, serving both as a mirror of its age and an agent of change.      Wagner’s seemingly paradoxical notion of art provides an apt introduction to historicist thinking. Obsessed with the idea of correspondence (or the lack of it between art and its times, nineteenth-century thinkers such as Heinrich Hübsch, Carl Bötticher and Gottfried Semper all responded to the perceived crisis. While Hübsch and Bötticher sought to alleviate the crisis by redefining this correspondence for a modern world, Semper presented a far more radical alternative. Not only did he see the current crisis as inevitable; he welcomed it as a necessary dissolution of an old order, out of which a new architecture could emerge. He thus anticipated modernists, such as Sigfried Giedion, for whom historicism was a necessary melt-down; an apocalypse, preparing for the advent of modernism. In this essay, I propose that crisis and style are intrinsically linked in modern thinking. To look closely at this coupling may throw new light not only on historicism but also on the noticeable unease with which the notion of style is treated in contemporary architectural history.

Competing order parameters in Fermi systems with engineered band dispersion

Science.gov (United States)

Wu, Chien-Te; Boyack, Rufus; Anderson, Brandon; Levin, K.

We explore a variety of competing phases in 2D and 3D Fermi gases in the presence of novel dispersion relations resulting from a shaken optical lattice. We incorporate spin imbalance along with attractive interactions. In 3D, at the mean field level we present phase diagrams reflecting the stability of alternative order parameters in the pairing (including LOFF) and charge density wave channels. We perform analogous studies in 2D, where we focus on the competition between different paired phases. Important in this regard is that our 2D studies are consistent with the Mermin Wagner theorem, so that, while there is competition, conventional superfluidity cannot occur

Harry-O'kuru, R E; Carriere, C J

2002-05-22

Asclepias syriaca L., the common milkweed, is a new industrial crop. The seed contains about 20-30 wt % of a highly unsaturated oil having unusual fatty acids. Exploring value-added products from the oil, milkweed triglycerides have been oxidized by in situ performic acid to the polyoxirane and polyhydroxy triglycerides (PHTG). The rheological properties of milkweed PHTG were characterized in various shear flows. Milkweed PHTG displayed nonlinear viscoelastic behavior at applied strains greater than 1%. Milkweed PHTG was found to obey time-strain separability. A nonlinear Wagner constitutive model was used successfully to qualitatively predict the behavior of milkweed PHTG in both start-up and cessation of steady-state shear flow.

Nonlinear aerodynamics of two-dimensional airfoils in severe maneuver

Scott, Matthew T.; Mccune, James E.

1988-01-01

This paper presents a nonlinear theory of forces and moment acting on a two-dimensional airfoil in unsteady potential flow. Results are obtained for cases of both large and small amplitude motion. The analysis, which is based on an extension of Wagner's integral equation to the nonlinear regime, takes full advantage of the trailing wake's tendency to deform under local velocities. Interactive computational results are presented that show examples of wake-induced lift and moment augmentation on the order of 20 percent of quasi-static values. The expandability and flexibility of the present computational method are noted, as well as the relative speed with which solutions are obtained.

The growth kinetics of the PbS nanoparticles follow the Lifshitz-Slyozov-Wagner model for Ostwald ripening, allowing direct estimation of the rate constants for the process. In addition, the extraction of absorption spectra of ultrasmall quantum dots is demonstrated for first time in an online manner.

This research thesis first addresses the reaction kinetics of oxygen on alloys. It presents some generalities on heterogeneous reactions (conventional theory, theory of jumps), discusses the core reaction (with the influence of pressure), discusses the influence of metal self-diffusion on metal oxidation kinetics (equilibrium conditions at the interface, hybrid diffusion regime), reports the application of the hybrid diffusion model to the study of selective oxidation of alloys (Wagner model, hybrid diffusion model) and the study of the oxidation kinetics of an alloy forming a solid solution of two oxides. The second part reports the investigation of the oxidation of single phase nickel and niobium alloys (phase α, β and γ)

Theoretical and Experimental Studies of Wave Impact underneath Decks of Offshore Platforms

Energy Technology Data Exchange (ETDEWEB)

Baarholm, Rolf Jarle

2001-07-01

The main objective of this thesis has been to study the phenomenon of water impact underneath the decks of offshore platforms due to propagating waves. The emphasis has been on the impact loads. Two theoretical methods based on two-dimensional potential theory have been developed, a Wagner based method (WBM) and a nonlinear boundary element method (BEM). A procedure to account for three-dimensional effects is suggested. The deck is assumed to be rigid. Initial studies of the importance of hydroelasticity for wave loads on an existing deck structure have been performed. For a given design wave, the local structural responses were found to behave quasi-static. Global structural response has not been studied. In the Wagner based method gravity is neglected and a linear spatial distribution of the relative impact velocity along the deck is assumed. The resulting boundary value problem is solved analytically for each time step. A numerical scheme for stepping the wetted deck area in time is presented. The nonlinear boundary element method includes gravity, and the exact impact velocity is considered. The incident wave velocity potential is given a priori, and a boundary value problem for the perturbation velocity potential associated with the impact is defined. The boundary value problem is solved for each time step by applying Green's second identity. The exact boundary conditions are imposed on the exact boundaries. A Kutta condition is introduced as the fluid flow reaches the downstream end of the deck. At present, the BEM is only applicable for fixed platform decks. To validate the theories, experiments have been carried out in a wave flume. The experiments were performed in two-dimensional flow condition with a fixed horizontal deck at different vertical levels above the mean free surface. The vertical force on the deck and the wetting of the deck were the primary parameters measured. Only regular propagating waves were applied. When a wave hits the deck, the

Modified Wagner model for the active-to-passive transition in the oxidation of Si3N4

Si 3 N 4 is used as the coating material of space shuttle structures which receive very high thermal fluxes during the atmospheric re-entry phase. Two main regimes govern the oxidation of Si 3 N 4 : the passive oxidation, with the formation of a protective silica layer leading generally to a mass gain, and the active oxidation, with vaporization of SiO leading to a mass loss of the sample. To ensure that silicon nitride will efficiently protect a material in given oxidizing environments, its own oxidation behaviour must be previously known. Therefore, the active-to-passive transition of Si 3 N 4 oxidation is a problem of deep scientific importance and of wide technological relevance. In this paper, a modified Wager model for the active-to-passive transition in the oxidation of Si 3 N 4 is presented, which includes the non-equilibrium effects caused by the mass transfer. The present theoretical calculations satisfactorily explained the reported experimental and theoretical data. The influence of flow rate on the active-to-passive transition boundary has been explained using our model. The rate controlling mechanism of the oxidation at the active-to-passive transition point is proposed

Rilke contra Wagner. Rilke’s early concept of Music and the Convergence of the Arts around 1900

Directory of Open Access Journals (Sweden)

Jacob-Ivan Eidt

2011-10-01

Full Text Available This article examines Rainer Maria Rilke’s fundamental distinction between the essence of music and poetry, concentrating on his earliest encounters with music around 1900 and their impact on his poetics. It places Rilke’s concept of music into the cultural con­text of the romantic experience and reception of music and the other arts in Germany at the turn of the century. Rilke’s early understanding is ultimately negative, deviating from the popularly held belief in fin de siècle Europe that all the arts are not just compatible but also in essence identical. For Rilke there can be neither a Wagnerian Gesamtkunswerk nor a greater underlying principle around which the arts could be united, despite his enthusias­tic integration of the visual arts into his poetics.

Highlights: > A covalent filler-matrix interface improves the dielectric properties of a polymer-particle nanocomposite dielectric. > A covalent interface reduced the polymer free volume around the nanoparticles as assessed through T{sub g} measurements. > Composite T{sub g} was raised and breakdown strength improved for nanocomposites with a covalent polymer-particle interface. > A larger Maxwell-Wagner (MW) relaxation correlated with reduced breakdown strengths and energy storage densities. > The MW relaxation could be considered a dielectric defect regarding breakdown strength and energy storage density. - Abstract: A composite approach to dielectric design has the potential to provide improved permittivity as well as high breakdown strength and thus afford greater electrical energy storage density. Interfacial coupling is an effective approach to improve the polymer-particle composite dielectric film resistance to charge flow and dielectric breakdown. A bi-functional interfacial coupling agent added to the inorganic oxide particles' surface assists dispersion into the thermosetting epoxy polymer matrix and upon composite cure reacts covalently with the polymer matrix. The composite then retains the glass transition temperature of pure polymer, provides a reduced Maxwell-Wagner relaxation of the polymer-particle composite, and attains a reduced sensitivity to dielectric breakdown compared to particle epoxy composites that lack interfacial coupling between the composite filler and polymer matrix. Besides an improved permittivity, the breakdown strength and thus energy density of a covalent interface nanoparticle barium titanate in epoxy composite dielectric film, at a 5 vol.% particle concentration, was significantly improved compared to a pure polymer dielectric film. The interfacially bonded, dielectric composite film had a permittivity {approx}6.3 and at a 30 {mu}m thickness achieved a calculated energy density of 4.6 J/cm{sup 3}.

Solid State Ionics: from Michael Faraday to green energy-the European dimension.

Solid State Ionics has its roots essentially in Europe. First foundations were laid by Michael Faraday who discovered the solid electrolytes Ag 2 S and PbF 2 and coined terms such as cation and anion , electrode and electrolyte . In the 19th and early 20th centuries, the main lines of development toward Solid State Ionics, pursued in Europe, concerned the linear laws of transport, structural analysis, disorder and entropy and the electrochemical storage and conversion of energy. Fundamental contributions were then made by Walther Nernst, who derived the Nernst equation and detected ionic conduction in heterovalently doped zirconia, which he utilized in his Nernst lamp. Another big step forward was the discovery of the extraordinary properties of alpha silver iodide in 1914. In the late 1920s and early 1930s, the concept of point defects was established by Yakov Il'ich Frenkel, Walter Schottky and Carl Wagner, including the development of point-defect thermodynamics by Schottky and Wagner. In terms of point defects, ionic (and electronic) transport in ionic crystals became easy to visualize. In an 'evolving scheme of materials science', point disorder precedes structural disorder, as displayed by the AgI-type solid electrolytes (and other ionic crystals), by ion-conducting glasses, polymer electrolytes and nano-composites. During the last few decades, much progress has been made in finding and investigating novel solid electrolytes and in using them for the preservation of our environment, in particular in advanced solid state battery systems, fuel cells and sensors. Since 1972, international conferences have been held in the field of Solid State Ionics, and the International Society for Solid State Ionics was founded at one of them, held at Garmisch-Partenkirchen, Germany, in 1987.

This paper reports on the synthesis of polycrystalline (Li,Ti)-doped NiO powders (i.e., Li{sub x}Ti{sub 0.1}Ni{sub 1−x}O, abbreviated as LTNO) by the solid-state synthesis method. Note that, the doping concentration of Ti is kept constant (x∼0.10) in the stoichiometry, the difference in the material behavior of LTNO samples can only be attributed to the effect of Li. X-ray diffraction patterns confirmed a cubic rock-salt structured NiO-based phase with the presence of minor NiTiO{sub 3} phase, were reported elsewhere [Venkata et al., Chem. Phys. Lett., 649 (2016) 115–118.]. Dense microstructures were obtained using ultra high resolution scanning electron microscope. A high dielectric constant (ε∼10{sup 4}) near room temperature at low-frequency was observed in LTNO ceramics. Weak temperature dependence of dielectric constant over the measured compositions (x = 0 to 0.10) was observed in the LTNO ceramics. A giant dielectric constant of 10{sup 4}–10{sup 5} at high temperatures (120–170 °C) for certain LTNO compositions (x = 0.15 to 0.3) was observed in the sintered ceramics. The origin of the high dielectric constant observed in these LTNO ceramics is attributed to the Maxwell–Wagner polarization mechanism and a thermally activated mechanism. - Highlights: • Li content strongly influences the structure and dielectric properties. • Li-incorporation enhances the dielectric properties of LTNO. • A giant dielectric constant of 10{sup 4}–10{sup 5} at high temperatures (120–170 °C). • Giant dielectric constant is attributed to the Maxwell–Wagner polarization. • NTCR behavior is also confirmed from impedance spectroscopy results.

Background: The aim of study was detailed analysis of the presentation of diabetic foot ulcers, characteristics and predictors of outcome (incidence of amputation in neuropathic, ischemic, neuro ischemic) in patients presenting with diabetic foot at our hospital. Methods: This prospective analytic study was conducted from January 2009-August 2010 at POF Hospital Wah Cantt. Diabetic patients who presented with foot ulcers were enrolled in this study. Demographics of patients along with ulcer size, type, site and Grade according to Wagner Classification were recorded. Wounds were managed with daily dressings, nursing care and de-sloughing of necrotic tissue along with appropriate antibiotic cover. Patients were followed over period until wound healed completely or a lower limb amputation performed, the outcome noted and patient was deemed to have completed study. Results: One hundred and fifteen patients with mean age 55.46 +- 8.23 years, both male and female were included in this study. Out of 115 patients 111 patients had Type-II diabetes while only 4 presented with Type-I. Mean Duration of diabetes was 14.61 +- 2.17 years. With respect to underlying causes 18.3% foot ulcers were ischemic, 22.6% were neuropathic and 59% were neuro-ischemic. Median ulcer size was 74% of ulcer classified as Wagner grade-II and III while 24% were of Grade-V. Lower limb amputation were performed in 25% of patients whereas limb salvage achieved in 75% of patients with wounds healed (median healing time 5 (3-10 weeks). Conclusion: Preservation of the limb function without endangering the patient must be a goal of treating diabetic foot. Once foot amputation is successful, rehabilitation with orthotic or prosthetic devices may allow years of a functional extremity along with preventive measures like cessation of smoking, daily foot hygiene and foot inspection.

Solid State Ionics: from Michael Faraday to green energy—the European dimension

Full Text Available Solid State Ionics has its roots essentially in Europe. First foundations were laid by Michael Faraday who discovered the solid electrolytes Ag2S and PbF2 and coined terms such as cation and anion, electrode and electrolyte. In the 19th and early 20th centuries, the main lines of development toward Solid State Ionics, pursued in Europe, concerned the linear laws of transport, structural analysis, disorder and entropy and the electrochemical storage and conversion of energy. Fundamental contributions were then made by Walther Nernst, who derived the Nernst equation and detected ionic conduction in heterovalently doped zirconia, which he utilized in his Nernst lamp. Another big step forward was the discovery of the extraordinary properties of alpha silver iodide in 1914. In the late 1920s and early 1930s, the concept of point defects was established by Yakov Il'ich Frenkel, Walter Schottky and Carl Wagner, including the development of point-defect thermodynamics by Schottky and Wagner. In terms of point defects, ionic (and electronic transport in ionic crystals became easy to visualize. In an 'evolving scheme of materials science', point disorder precedes structural disorder, as displayed by the AgI-type solid electrolytes (and other ionic crystals, by ion-conducting glasses, polymer electrolytes and nano-composites. During the last few decades, much progress has been made in finding and investigating novel solid electrolytes and in using them for the preservation of our environment, in particular in advanced solid state battery systems, fuel cells and sensors. Since 1972, international conferences have been held in the field of Solid State Ionics, and the International Society for Solid State Ionics was founded at one of them, held at Garmisch-Partenkirchen, Germany, in 1987.

Effect of synthesis route on the multiferroic properties of BiFeO3: A comparative study between solid state and sol–gel methods

International Nuclear Information System (INIS)

Suresh, Pittala; Srinath, S.

2015-01-01

Polycrystalline BiFeO 3 (BFO) powder was prepared through optimized solid state (SS) and sol–gel (SG) reaction methods. The effect of preparation routes on the crystal purity and multiferroic properties of the BFO was investigated. Sol–gel synthesis results almost a single-phase material at relatively lower temperatures while the solid-state method results into BFO with a small amount of Bi 2 Fe 4 O 9 secondary phase. The grain size of SG processed sample reduces to half the size of the one that is prepared by SS. Elemental analysis shows a stoichiometric Bi:Fe content for SG samples by restricting the Bi loss. In comparison with the SS samples, dielectric constant of SG samples exhibit higher values with Maxwell–Wagner type dielectric dispersion. A cusp at 50 K was seen in M–T curves for SS samples, for which no frequency dependence was observed in a.c susceptibility measurements ruling out the earlier predictions of spin glass nature in this system. M−H loops show a typical antiferromagnetic nature at 300 K while a weak ferromagnetic behavior is found at 10 K. A slight increase in H C and M r was observed for SG samples over SS. The improved properties of SG processed BFO makes it more promising for applications. - Highlights: • Optimized conditions to attain the BiFeO 3 with minimized impurities are reported. • The influence of the impurities on the dielectric, magnetic properties is reported. • Maxwell–Wagner relaxation is found for BiFeO 3 prepared by sol–gel technique. • a.c. susceptibility measurements ruled out the possibility of spin glass nature. • The anomalous behavior of H C with the temperature is reported

Role of thermal two-phonon scattering for impurity dynamics in a low-dimensional Bose-Einstein condensate

Science.gov (United States)

Lausch, Tobias; Widera, Artur; Fleischhauer, Michael

2018-03-01

We numerically study the relaxation dynamics of a single, heavy impurity atom interacting with a finite one- or two-dimensional, ultracold Bose gas. While there is a clear separation of time scales between processes resulting from single- and two-phonon scattering in three spatial dimensions, the thermalization in lower dimensions is dominated by two-phonon processes. This is due to infrared divergences in the corresponding scattering rates in the thermodynamic limit, which are a manifestation of the Mermin-Wagner-Hohenberg theorem. This makes it necessary to include second-order phonon scattering above a crossover temperature T2ph . T2ph scales inversely with the system size and is much smaller than currently experimentally accessible.

Saini, Deepash S.; Singh, Sunder; Kumar, Anil; Bhattacharya, D.

2018-05-01

In the present work, dielectric and modulus studies of polycrystalline BaZrO3 ceramic, prepared by modified combustion method followed by conventional sintering, are investigated over the frequency range of 100 Hz to 106 Hz at different temperatures from 250 to 500 °C in air. The high value of dielectric constant (ɛ' ˜ 103) of BaZrO3 at high temperature and low frequency can be attributed to the Maxwell-Wagner polarization mechanism as well as to the thermally activated mechanism of charge carriers. Electric modulus reveal two type relaxations in the 250 °C to 800 °C temperature region as studied at different frequencies over 100 Hz to 106 Hz in air.

Some of these compounds are considered important drugs in modern medicine, such as atropine and morphine. Plants are considered the most important source of alkaloids. Therefore, investigating the presence of alkaloids in different plants is very important. Usually, alkaloids in plants are identified by methods such as those of Dragendorf, Wagner and Meyer, among others, which require milligrams of alkaloids for identification. In the present study, a fast and sensitive procedure for detecting of alkaloids in plants is presented.   "n"nMethods: Twelve dried plants samples were investigated for the presence alkaloids.

Truncation effects in the functional renormalization group study of spontaneous symmetry breaking

International Nuclear Information System (INIS)

Defenu, N.; Mati, P.; Márián, I.G.; Nándori, I.; Trombettoni, A.

2015-01-01

We study the occurrence of spontaneous symmetry breaking (SSB) for O(N) models using functional renormalization group techniques. We show that even the local potential approximation (LPA) when treated exactly is sufficient to give qualitatively correct results for systems with continuous symmetry, in agreement with the Mermin-Wagner theorem and its extension to systems with fractional dimensions. For general N (including the Ising model N=1) we study the solutions of the LPA equations for various truncations around the zero field using a finite number of terms (and different regulators), showing that SSB always occurs even where it should not. The SSB is signalled by Wilson-Fisher fixed points which for any truncation are shown to stay on the line defined by vanishing mass beta functions.

Full Text Available This paper examines the short and long-run relationship between goverment revenues, expenditures, GNP and interest rates for Turkey for the period 1987:1-2003:3, using error correction model (ECM and the augmented vector autoregressive (VAR model developed in Toda-Yamamoto (1995. The results indicate that there is one long-run equilibrium relationship among the four variables, and the causal relationship flows unidirectionally from government revenues to expentitures both in the short and long-run, providing support for the tax-spend theory.The results further reveal that the unidirectional causal impact of revenues on expentitures is significantly negative as hypothesized by Buchanan and Wagner. Thus, higher taxes seem an optimal resolution to the budget deficits in Turkey.

1987-01-01

The addition of nitriles of varying nucleophilicity to isocamphanol and exo-1,5,5-trimethyl-bicyclo[2.2.1]heptan-2-ol (isofenchol) was investigated. The authors examined the effect of the reaction conditions on the yield and structure of the target products of the reaction: N-substituted amides. As a result of the study, it was shown that in the reaction with chloroacetonitrile, propionitrile, methoxypropionitrile, isovaleronitrile, and phenylacetonitrile under the conditions of the Ritter reaction, isocamphanol is transformed into the corresponding substituted exo-N-acyl-1,7,7-trimethylbicyclo[2.2.1]hept-2-ylamines, as in the reaction with aceto- and benzonitriles, due to 2,6-hydride displacement accompanied by Wagner-Meerwein rearrangement. The structures of these amides were demonstrated by PMR spectroscopy

The capacity and the dielectric loss tangent of a Gd x Mn1- x Se ( x ≤ 0.2) solid solution have been measured in the frequency range 1-300 kHz without a magnetic field and in a magnetic field of 8 kOe in the temperature range 100-450 K, and the magnetic moment of the solid solution has been measured in a field of 8.6 kOe. The magnetocapacity effect and the change in the magnetocapacity sign have been observed in room temperature in the paramagnetic region. A correlation of the changes in the dielectric permittivity and the magnetic susceptibility with temperature has been revealed. The magnetocapacity is described using the model with orbital electron ordering and the Maxwell-Wagner model.

Mechanisms and kinetics of precipitate restructuring during irradiation

Potter, D.I.; Wiedersich, H.

1979-01-01

Irradiations were performed at temperatures from 400 to 700 0 C using 3.0-MeV 58 Ni + ions in order to investigate γ'-precipitate restructuring in two model alloys: Ni-12.8 at% Al and Ni-12.7 at% Si. The precipitates coarsened, with the third power of the average diameter proportional to the damage dose. The temperature dependence of the rate constants for irradiated specimens is described in terms of a modified Lifschitz-Slyozov-Wagner coarsening model that includes radiation-enhanced diffusion. Redistribution of precipitate by enhanced precipitation (Ni-Si) or precipitate dissolution (Ni-Al) at point-defect sinks caused maxima in γ' size with dose. Precipitate redistribution at the free surfaces of irradiated thin foils and at γ/γ' particle interfaces is described. (Auth.)

In this paper a computation model of corrosion rate-grain size of nanocrystalline and ultra-fine zirconium has been presented. The model is based on the Wagner's theory and the electron theory of solids. The conductivity, electronic mean free path and grain size of metal were considered. By this model, the corrosion rate of zirconium metal under different temperature was computed. The results show that the corrosion weight gain and rate constant of nanocrystalline zirconium is lower than that of zirconium with coarse grain size. And the corrosion rate constant and weight gain of nanocrystalline zirconium metal decrease with the decrease of grain size. So the refinement of grain size can remarkably improve the corrosion resistance of zirconium metal. (authors)

Full Text Available A silver nanoparticles self-assembled monolayer (SAM was incorporated in pentacene field-effect transistor and its effects on the carrier injection and transport were investigated using the current-voltage (I − V and impedance spectroscopy (IS measurements. The I − V results showed that there was a significant negative shift of the threshold voltage, indicating the hole trapping inside the devices with about two orders higher in the contact resistance and an order lower in the effective mobility when a SAM was introduced. The IS measurements with the simulation using a Maxwell-Wagner equivalent circuit model revealed the existence of multiple trapping states for the devices with NPs, while the devices without NPs exhibited only a single trap state.

Random-phase-approximation approach to optical and magnetic excitations in the two-dimensional multiband Hubbard model

International Nuclear Information System (INIS)

Yonemitsu, K.; Bishop, A.R.

1992-01-01

As a convenient qualitative approach to strongly correlated electronic systems, an inhomogeneous Hartree-Fock plus random-phase approximation is applied to response functions for the two-dimensional multiband Hubbard model for cuprate superconductors. A comparison of the results with those obtained by exact diagonalization by Wagner, Hanke, and Scalapino [Phys. Rev. B 43, 10 517 (1991)] shows that overall structures in optical and magnetic particle-hole excitation spectra are well reproduced by this method. This approach is computationally simple, retains conceptual clarity, and can be calibrated by comparison with exact results on small systems. Most importantly, it is easily extended to larger systems and straightforward to incorporate additional terms in the Hamiltonian, such as electron-phonon interactions, which may play a crucial role in high-temperature superconductivity

2018-04-01

We present dielectric, complex impedance, modulus spectroscopy and AC conductivity studies of the compound BaFe10Sc2O19 as a function of temperature and frequency to understand the conduction mechanism. The variation in complex dielectric constant with frequency and temperature were analyzed on the basis of Maxwell-Wagner-Koop's theory and charge hopping between ferrous and ferric ions. The complex impedance spectroscopy study shows only grain contribution whereas complex modulus plot shows two semicircular arcs which indicate both grain and grain boundary contributions in conduction mechanism. AC conductivity has also been evaluated which follows the Jonscher's law. The activation energy calculated from temperature dependence of DC conductivity comes out to be Ea˜ 0.31eV.

Non steady-state model for dry oxidation of nuclear wastes metallic containers in long term interim storage conditions

International Nuclear Information System (INIS)

Bertrand, Nathalie; Desgranges, Clara; Poquillon, Dominique; Monceau, Daniel

2006-01-01

For high-level nuclear waste containers in long-term interim storage, dry oxidation will be the first and the main degradation mode. The reason is that, for this kind of waste, the temperature on the surface of the containers will be high enough to avoid any condensation phenomena for several years. Even if the scale growth kinetics is expected to be very slow since the temperature will be moderate at the beginning of the storage (around 300 deg. C) and will keep on decreasing, the metal thickness lost by dry oxidation over such a long period must be evaluated with a good reliability. To achieve this goal, modelling of the oxide scale growth is necessary and this is the aim of the dry oxidation studies, performed in the frame of the COCON programme. All existing oxidation models are based on the two main oxidation theories developed by Wagner between the 1930's and 1970's on the one hand, and by Cabrera and Mott in the 1960 and next by Fromhold on the other hand. These used to be associated with high temperature behaviour for Wagner's theory and with low temperature for the second one. Indeed it is certainly more relevant to consider their range of application in terms of the oxide scale thickness rather than in terms of temperature. The question is posed about which theory should an appropriate model rely on. It can be expected that the oxide scale could have a thickness ranging from a few tens of nanometers up to several tens of micrometers depending on temperature and class of alloys chosen. At the present time, low-alloyed steels or carbon steels are considered candidate materials for high-level nuclear waste containers in long term interim storage. For this type of alloys, the scale formed during the dry oxidation stage will be 'rapidly' thick enough to neglect the Mott field. Hence, in a first step, some basic models based on a parabolic rate assumption, that is to say Wagner's model, have been derived from experimental data on iron and on low-alloy steel

Full Text Available Background: The World Health Organisation indicates that the number of people with type 2 diabetes mellitus is more than 366 million and is expected to increase to 552 million by 2030, i.e., 8.3% of the total adult population. Each year, 14.9% of patients with this disease experience plantar ulcers, which in most cases are resistant to standard treatments. Of these, 15–20% require radical amputation within five years of diagnosis. Material and methods: This is a retrospective study reviewing the records of patients with type 2 diabetes mellitus and complications from lower limb injuries. We selected 220 records of patients with type 2 diabetes mellitus and lower limb injuries, undergoing hyperbaric oxygen therapy. We grouped wounds according to the Wagner Grading System and classified them according to the Skeik Modified Scale to determine the effect of hyperbaric oxygen therapy (HBOT on the healing time of wounds. By way of comparison, the study was divided a second time, adjusting the initial population so as to include only cases that benefited from HBOT. Results: Overall improvement was achieved in 149 patients (67.7%, with a greater response in Wagner stages II and III. In patients who received 16–30 sessions, it was found that 77 (64.16% maintained their improvement and only 43 (28.85% had a relapse. Conclusions: At the end of the study, we found that HBOT is favourable and permanent in 52.72% of patients, seeing temporary improvement in 15%. This opens up the possibility of new developments that successfully determine suitable selective parameters and lead to a speedy recovery.

Selective Oxidation of a 0.1C-6Mn-2Si Third Generation Advanced High-Strength Steel During Dew-Point Controlled Annealing

Pourmajidian, Maedeh; McDermid, Joseph R.

2018-03-01

The present study investigates the selective oxidation of a 0.1C-6Mn-2Si medium-Mn advanced high-strength steel during austenization annealing heat treatments as a function of process atmosphere oxygen partial pressure and annealing time. It was determined that the surface oxide growth kinetics followed a parabolic rate law with the minimum rate belonging to the lowest oxygen partial pressure atmosphere at a dew point of 223 K (- 50 °C). The chemistry of the surface and subsurface oxides was studied using STEM + EELS on the sample cross sections, and it was found that the surface oxides formed under the 223 K (- 50 °C) dew-point atmosphere consisted of a layered configuration of SiO2, MnSiO3, and MnO, while in the case of the higher pO2 process atmospheres, only MnO was detected at the surface. Consistent with the Wagner calculations, it was shown that the transition to internal oxidation for Mn occurred under the 243 K (- 30 °C) and 278 K (+ 5 °C) dew-point atmospheres. However, the predictions of the external to internal oxidation for Si using the Wagner model did not correlate well with the experimental findings nor did the predictions of the Mataigne et al. model for multi-element alloys. Investigations of the internal oxide network at the grain boundaries revealed a multilayer oxide structure composed of amorphous SiO2 and crystalline MnSiO3, respectively, at the oxide core and outer shell. A mechanism for the formation of the oxide morphologies observed, based on kinetic and thermodynamic factors, was proposed. It is expected that only the fine and nodule-like MnO oxides formed on the surface of the samples annealed under the 278 K (+ 5 °C) dew-point process atmosphere for 60 and 120 seconds are sufficiently thin and of the desired dispersed morphology to promote reactive wetting by the molten galvanizing bath.

2009-06-01

Full Text Available The Q factor of a coil can be measured by measuring accurately the inductance and effective resistance of the coil for a specific signal. The inductance of an inductive coil is generally measured by usual inductive circuit like Maxwell-Wein Bridge, Hay Bridge etc. which suffer from error due to stray capacitance between bridge nodal point and ground and stray inductance of the inductive coil. The conventional Wagner Earth Technique is not suitable for continuous measurement. In the present paper, a modified operational amplifier based Maxwell-Wein Bridge measurement technique has been proposed in which stray capacitance and stray inductance are minimized. The experiment is done for different value of known inductance & Q factor for a specific signal. The linear characteristic with a good repeatability, linearity and variable sensitivity has been described.

Long-wavelength fluctuations and the glass transition in two dimensions and three dimensions.

Phase transitions significantly differ between 2D and 3D systems, but the influence of dimensionality on the glass transition is unresolved. We use microscopy to study colloidal systems as they approach their glass transitions at high concentrations and find differences between two dimensions and three dimensions. We find that, in two dimensions, particles can undergo large displacements without changing their position relative to their neighbors, in contrast with three dimensions. This is related to Mermin-Wagner long-wavelength fluctuations that influence phase transitions in two dimensions. However, when measuring particle motion only relative to their neighbors, two dimensions and three dimensions have similar behavior as the glass transition is approached, showing that the long-wavelength fluctuations do not cause a fundamental distinction between 2D and 3D glass transitions.

Tricritical behaviour in the phase transition induced by electron-hole pairing

International Nuclear Information System (INIS)

Crisan, M.

1980-01-01

The electron-hole pairing, which is possible in metals or semiconductors, can give condensed phases with two order parameters. If the coupling between the two order parameters is considered, the free energy functional is similar with the free energy of a n-component spin system with cubic anisotropy. Using the Wagner hypothesis (tricritical scaling) the non-linear scaling fields have been calculated. In order to perform the calculation of the nonlinear fields we used the method given by Rudnick and Nelson to solve the recursion relations for the 4-epsilon-dimensional system with n=6 components. The present calculation in the frame-work of the renormalization-group approach confirms the result obtained in the mean-field theory that the coupling of the two order parameters induces a first order phase transition.

2008-01-01

Full Text Available This article deals with new concepts in urban planning at the turn of the 19th century. It represents three key persons, all architects and urban planners: Camillo Sitte, Otto Wagner and Maks Fabiani. All three left an indelible mark on urban planning in the Hapsburg Monarchy. In particular, it focuses on Maks Fabiani, whose work is closely related with the reconstruction of Ljubljana after the earthquake at the end of the 19th and the beginning of the 20th century. Even though Fabiani was one of the most distinguished and respected urban planners in Vienna, his contribution to the history and theory of urban planning was until now relatively overlooked and not stressed enough upon in the context of the urban history within the Austro-Hungarian Empire.

Ostwald Ripening Process of Coherent β′ Precipitates during Aging in Fe0.75Ni0.10Al0.15 and Fe0.74Ni0.10Al0.15Cr0.01 Alloys

Full Text Available The Ostwald ripening process was studied in Fe0.75Ni0.10Al0.15 and Fe0.74Ni0.10Al0.15Cr0.01 alloys after aging at 750, 850, and 950°C for different times. The microstructural evolution shows a rounded cube morphology (Fe, NiAl β′ precipitates aligned in the ferrite matrix, which changes to elongated plates after prolonged aging. The variation of the equivalent radii of precipitates with time follows the modified Lifshitz-Slyozov-Wagner theory for diffusion-controlled coarsening. Thermo-Calc analysis shows that the chromium content is richer in the matrix than in the precipitates which causes higher hardness and coarsening resistance in the aged Fe0.74Ni0.10Al0.15Cr0.01 alloy.

Meier, P

2013-09-01

The number of retinal detachments in children is very low in comparison to the number in adults. One predisposing factor for development of paediatric retinal detachment is suffering from hereditary vitreoretinal degeneration (e.g., Stickler syndrome, Wagner syndrome, Kniest dysplasia, familial exudative vitreoretinopathy, congenital X-linked retinoschisis, Knobloch syndrome, incontinentia pigmenti, Norrie disease). Hereditary vitreoretinopathies are characterised by an abnormal-appearing vitreous gel with associated retinal changes. In most of these eyes further ocular abnormalities can be diagnosed. A group of hereditary disorders is associated with characteristic systemic abnormalities. Allied conditions should be considered in the clinical diagnosis. Vitreoretinopathies are the most common cause of inherited retinal detachment. In most eyes primary vitrectomy is necessary, and disease-specific surgical treatment is discussed.

Conductivity enhancement in SiO2 doped PVA:PVDF nanocomposite polymer electrolyte by gamma ray irradiation

Science.gov (United States)

Hema, M.; Tamilselvi, P.; Pandaram, P.

2017-07-01

Nanocomposite polymer electrolyte has been irradiated with 15 Gy Gamma rays. Exposure of gamma radiation caused scissoring and crosslinking of polymer chains thereby increasing amorphous phase of the polymer matrix because of which the ionic conductivity has been enhanced. Ionic conductivity of irradiated nanocomposite polymer electrolyte is enhanced to 9.4 × 10-4 Scm-1 at 303 K compared to un-irradiated system (σ ∼ 1.7 × 10-4 Scm-1). Temperature dependence of ionic conductivity of both un-irradiated and irradiated systems obeys VTF relation. Frequency and temperature dependence of dielectric and modulus of both systems have been analyzed. The ionic transference number of polymer electrolyte has been calculated by Wagner's polarization technique and it confirms that conducting species are predominantly due to ions in both systems.

Synthesis of N-methyl and N-11C-methyl spiperone by phase transfer catalysis in anhydrous solvent

Spiperone, a butyrophenone neuroleptic drug, has been used in binding studies of dopamine receptors. Langstrom et al. developed N- 11 C-methyl spiperone, and, in cooperate with Wagner et al., made it possible to visualize the distribution of dopamine receptors in the human brain in vivo. In this paper, we independently developed another synthetic method of N- 11 C-methyl spiperone using the phase transfer catalyst in an anhydrous solvent. Separation of the product is feasible only by passing the reactant solution through a Millipore filter and injecting it onto high pressure liquid chromatography (HPLC). The time required for the synthesis and purification of N- 11 C-methyl spiperone from 11 C-methyl iodide and spiperone was 20 min. Radiochemical yield exceeded 35 % against 11 C-methyl iodide without correcting decay of the radioactivity. (author)

Effect of annealing and biaxial deformation on the dielectric properties of composites of multiwall carbon nanotubes and poly(ethylene terephthalate)

Urvakis, Marius; Kupreviciute, Auste; Banys, Juras; Macutkevic, Jan; Mayoral, Beatriz; McNally, Tony

2012-01-01

The dielectric properties of composites of poly(ethylene terephthalate) (PET) with MWCNTs were investigated over a wide frequency and temperature range below and close to the electrical percolation threshold. In composites with 1 wt.% multiwall carbon nanotubes (MWCNT) inclusions, the dielectric properties below room temperature are mostly determined by β relaxation, as a consequence of the rotation of PET molecules. In stretched samples, the CNTs are oriented at about 45 deg to the stretch direction. Such deformation increased the potential for molecular rotation. However, annealing after stretching increased homogeneity of the composite and decreased the potential barrier for polymer chain rotation. Electrical conductivity effects and Maxwell-Wagner polarization mostly cause the dielectric properties of the samples with 2% MWCNT inclusions. The potential barrier for carrier tunneling is lowest in the annealed sample.

Point defect thermodynamics and diffusion in Fe3C: A first-principles study

International Nuclear Information System (INIS)

Chao Jiang; Uberuaga, B.P.; Srinivasan, S.G.

2008-01-01

The point defect structure of cementite (Fe 3 C) is investigated using a combination of the statistical mechanical Wagner-Schottky model and first-principles calculations within the generalized gradient approximation. Large 128-atom supercells are employed to obtain fully converged point defect formation energies. The present study unambiguously shows that carbon vacancies and octahedral carbon interstitials are the structural defects in C-depleted and C-rich cementite, respectively. The dominant thermal defects in C-depleted and stoichiometric cementite are found to be carbon Frenkel pairs. In C-rich cementite, however, the primary thermal excitations are strongly temperature-dependent: interbranch, Schottky and Frenkel defects dominate successively with increasing temperature. Using the nudged elastic band technique, the migration barriers of major point defects in cementite are also determined and compared with available experiments in the literature

The Simulation of Precipitation Evolutions and Mechanical Properties in Friction Stir Welding with Post-Weld Heat Treatments

Science.gov (United States)

Zhang, Z.; Wan, Z. Y.; Lindgren, L.-E.; Tan, Z. J.; Zhou, X.

2017-12-01

A finite element model of friction stir welding capable of re-meshing is used to simulate the temperature variations. Re-meshing of the finite element model is used to maintain a fine mesh resolving the gradients of the solution. The Kampmann-Wagner numerical model for precipitation is then used to study the relation between friction stir welds with post-weld heat treatment (PWHT) and the changes in mechanical properties. Results indicate that the PWHT holding time and PWHT holding temperature need to be optimally designed to obtain FSW with better mechanical properties. Higher precipitate number with lower precipitate sizes gives higher strength in the stirring zone after PWHT. The coarsening of precipitates in HAZ are the main reason to hinder the improvement of mechanical property when PWHT is used.

Leo Tolstoy, Mikhail Artsybashev, and Richard Wagner: About One Case of Polemics in Tolstoy’s The Circle of Reading

Directory of Open Access Journals (Sweden)

Anastasia A. Tulyakova

2017-12-01

Full Text Available The article deals with a case from the creative history of Leo Tolstoy’s The Circle of Reading (1908, when Tolstoy included the revised story of Guy de Maupassant’s Le Port under the title “Sisters” in the second edition of the book. The author proves that the reason for Tolstoy’s decision was his polemic with “saninstvo” as one of the most fashionable ethical trends of the first decade of the 1900s. The key component of Sanin’s behavior and hedonistic philosophy in Mikhail Artsybashev’s novel was incest. Maupassant’s novella is based on the same plot. On the basis of Tolstoy’s nonfictional texts of the 1890s, including the treatise What Is Art? (1898, the article reconstructs the writer’s view on the forms and boundaries of the representation of incest in Richard Wagner’s operas and in Friedrich Nietzsche’s philosophy, with which Tolstoy also polemicized and in connection with which he stated the ethical potential of art and its permissiveness. From this perspective, Tolstoy’s reaction to Artsybashev’s novel, combining the motives of incest and extreme individualism, turns out to be a new phase of the old dispute. Tolstoy included the story “Sisters” in the second edition of The Circle of Reading as a response to the philosophy of “saninstvo.” Thus, Tolstoy’s collection of wise thoughts can be considered not only as didactic, but also as a polemical text, and deeply rooted in the ideological context of the 1890s‒1900s.

Temporal maps and informativeness in associative learning.

Balsam, Peter D; Gallistel, C Randy

2009-02-01

Neurobiological research on learning assumes that temporal contiguity is essential for association formation, but what constitutes temporal contiguity has never been specified. We review evidence that learning depends, instead, on learning a temporal map. Temporal relations between events are encoded even from single experiences. The speed with which an anticipatory response emerges is proportional to the informativeness of the encoded relation between a predictive stimulus or event and the event it predicts. This principle yields a quantitative account of the heretofore undefined, but theoretically crucial, concept of temporal pairing, an account in quantitative accord with surprising experimental findings. The same principle explains the basic results in the cue competition literature, which motivated the Rescorla-Wagner model and most other contemporary models of associative learning. The essential feature of a memory mechanism in this account is its ability to encode quantitative information.

Dill, P L; Henley, T B

1998-01-01

Perceived stress and stressors of nontraditional (returning-adult) and traditional college students were compared. Forty-seven nontraditional students 24-54 years old and 47 traditional students, matched for demographics, completed the Adolescent Perceived Events Scale (Compas, Davis, Forsythe, & Wagner, 1987) for college students. They rated 210 life events according to the desirability, impact, and frequency of the events. Significant differences were found between the nontraditional and traditional students for events in the following categories: academics, peer and social relations, family and network, autonomy and responsibility, and intimacy. Nontraditional students enjoyed going to classes and doing homework more, whereas traditional students worried more about school performance. Peer events, including social activities, had much more impact on traditional students, whereas nontraditional students reported much more responsibility in the home. The results suggest that there are significant differences between the groups in their perceptions of stressors.

Wagner’s law versus Keynesian hypothesis: Evidence from pre-WWII Greece

Directory of Open Access Journals (Sweden)

Antonis Antoniou

2013-01-01

Full Text Available With data of over a century, 1833-1938, this paper attempts, for the first time, to analyze the causal relationship between income and government spending in the Greek economy for such a long period; that is, to gain some insight into Wagner and Keynesian Hypotheses. The time period of the analysis represents a period of growth, industrialization and modernization of the economy, conditions which are conducive to Wagner’s Law but also to the Keynesian Hypothesis. The empirical analysis resorts to Autoregressive Distributed Lag (ARDL Cointegration method and tests for the presence of possible structural breaks. The results reveal a positive and statistically significant long run causal effect running from economic performance towards the public size giving support to Wagner’s Law in Greece, whereas for the Keynesian hypothesis some doubts arise for specific time sub-periods.

[The last melancholia of Alonso Quijano, the Righteous].

1994-03-01

In Cervantes' immortal novel, "Don Quixote" is the nom de guerre that Alonso Quijano--a honest Spanish yeoman nicknamed "The Upright One"--adopts under the spell of insanity that has lured him into being a knight rider. A psycho-spiritual analysis of Don Quixote's return to mental health is presented, covering the time-span between Don Quixote's coming back to this native village and his last days. By way of a "historical diagnosis", the author proposes some clinical explanations: Goodman Quijano's last illness might have been a plasmodium falciparum-caused malaria; malaria, however did not contribute to reinstate soundmindedness (as per Wagner von Jauregg's therapeutic criteria, for example). Goodman Quijano's last fit of melancholy disclosed contempu mundi in him, a renunciation giving way to a joyful lucidity--in other words, a psychological awakening to a sublime conscience level of genuine spiritual characteristics.

Individuals with chronic obstructive pulmonary disease (COPD) face significant challenges due to frequent distressing dyspnea and deficits related to activities of daily living. Individuals with COPD are often hospitalized frequently for disease exacerbations, negatively impacting quality of life and healthcare expenditure burden. The home-based chronic care model (HBCCM) was designed to address the needs of patients with chronic diseases. This model facilitates the re-design of chronic care delivery within the home health sector by ensuring patient-centered evidence-based care. This HBCCM foundation is Dr. Edward Wagner s chronic care model and has four additional areas of focus: high touch delivery, theory-based self management, specialist oversight and the use of technology. This article will describe this model in detail and outline how model use for patients with COPD can bring value to stakeholders across the health care continuum.

Spectral distribution of solo voice and accompaniment in pop music.

Science.gov (United States)

Borch, Daniel Zangger; Sundberg, Johan

2002-01-01

Singers performing in popular styles of music mostly rely on feedback provided by monitor loudspeakers on the stage. The highest sound level that these loudspeakers can provide without feedback noise is often too low to be heard over the ambient sound level on the stage. Long-term-average spectra of some orchestral accompaniments typically used in pop music are compared with those of classical symphonic orchestras. In loud pop accompaniment the sound level difference between 0.5 and 2.5 kHz is similar to that of a Wagner orchestra. Long-term-average spectra of pop singers' voices showed no signs of a singer's formant but a peak near 3.5 kHz. It is suggested that pop singers' difficulties to hear their own voices may be reduced if the frequency range 3-4 kHz is boosted in the monitor sound.

Cointegration and Causality between Public Expenditure and Economic Growth: Case of Kyrgyzstan

Full Text Available According to Wagner’s law there is unidirectional relationship from economic growth to public expenditure. Wagner’s states that increase of national income leads to faster growth of public expenditure. In other words, out of economic and social development in the country, people will demand more public goods and it will increase public expenditure at a faster rate than national income. This study is analyzing the long term and causality relationship between public expenditure and economic growth in Kyrgyzstan and tests the validity of Wagner's law in Kyrgyz economy by using an ARDL and Error Correction models over the period 1995 to 2014. Empirical results showed that there is an unidirectional causality relationship between economic growth and public expenditure in long term. Empirical evidence is support the validity of Wagner’s law in Kyrgyz economy.

Verbal working memory predicts co-speech gesture: evidence from individual differences.

Science.gov (United States)

Gillespie, Maureen; James, Ariel N; Federmeier, Kara D; Watson, Duane G

2014-08-01

Gesture facilitates language production, but there is debate surrounding its exact role. It has been argued that gestures lighten the load on verbal working memory (VWM; Goldin-Meadow, Nusbaum, Kelly, & Wagner, 2001), but gestures have also been argued to aid in lexical retrieval (Krauss, 1998). In the current study, 50 speakers completed an individual differences battery that included measures of VWM and lexical retrieval. To elicit gesture, each speaker described short cartoon clips immediately after viewing. Measures of lexical retrieval did not predict spontaneous gesture rates, but lower VWM was associated with higher gesture rates, suggesting that gestures can facilitate language production by supporting VWM when resources are taxed. These data also suggest that individual variability in the propensity to gesture is partly linked to cognitive capacities. Copyright © 2014 Elsevier B.V. All rights reserved.

A new model for prediction of dispersoid precipitation in aluminium alloys containing zirconium and scandium

International Nuclear Information System (INIS)

Robson, J.D.

2004-01-01

A model has been developed to predict precipitation of ternary Al 3 (Sc, Zr) dispersoids in aluminium alloys containing zirconium and scandium. The model is based on the classical numerical method of Kampmann and Wagner, extended to predict precipitation of a ternary phase. The model has been applied to the precipitation of dispersoids in scandium containing AA7050. The dispersoid precipitation kinetics and number density are predicted to be sensitive to the scandium concentration, whilst the dispersoid radius is not. The dispersoids are predicted to enrich in zirconium during precipitation. Coarsening has been investigated in detail and it has been predicted that a steady-state size distribution is only reached once coarsening is well advanced. The addition of scandium is predicted to eliminate the dispersoid free zones observed in scandium free 7050, greatly increasing recrystallization resistance

2016-06-01

Rhegmatogenous retinal detachment (RRD) is a common and potentially blinding surgical retinal disease. While the precise molecular mechanisms leading to RRD are poorly understood, there is an increasing body of literature supporting the role of heritable factors in the pathogenesis of the condition. Much work has been undertaken investigating genes important in syndromic forms of RRD (e.g., Stickler, Wagner Syndrome, etc.) and research pertaining to genetic investigations of idiopathic or non-syndromic RRD has also recently been reported. To date, at least 12 genetic loci have been implicated in the development of syndromes of which RRD is a feature. A recent GWAS identified five loci implicated in the development of idiopathic RRD.This article provides an overview of the genetic mechanisms of both syndromic and idiopathic RRD. The genetics of predisposing conditions, such as myopia and lattice degeneration, are also discussed.

Anisotropic Ripple Deformation in Phosphorene.

Kou, Liangzhi; Ma, Yandong; Smith, Sean C; Chen, Changfeng

2015-05-07

Two-dimensional materials tend to become crumpled according to the Mermin-Wagner theorem, and the resulting ripple deformation may significantly influence electronic properties as observed in graphene and MoS2. Here, we unveil by first-principles calculations a new, highly anisotropic ripple pattern in phosphorene, a monolayer black phosphorus, where compression-induced ripple deformation occurs only along the zigzag direction in the strain range up to 10%, but not the armchair direction. This direction-selective ripple deformation mode in phosphorene stems from its puckered structure with coupled hinge-like bonding configurations and the resulting anisotropic Poisson ratio. We also construct an analytical model using classical elasticity theory for ripple deformation in phosphorene under arbitrary strain. The present results offer new insights into the mechanisms governing the structural and electronic properties of phosphorene crucial to its device applications.

Dispersion of Dielectric Permittivity in a Nanocrystalline Cellulose-Triglycine Sulfate Composite at Low and Ultralow Frequencies

Science.gov (United States)

Thu'o'ng, Nguyen Hoai; Sidorkin, A. S.; Milovidova, S. D.

2018-03-01

The dispersion of dielectric permittivity in nanocrystalline cellulose-triglycine sulfate composites is studied in the range of frequencies from 10-3 to 106 Hz, at temperatures varying from room temperature to the temperature of phase transition in this composite (54°C), in weak electric fields (1 V cm-1). Two behaviors for the dielectric dispersion are identified in the studied frequency range: at ultralow frequencies (10-3-10 Hz), the dispersion is due to Maxwell-Wagner polarization, while at higher frequencies (10-106 Hz), the dispersion is due to the movement of domain walls in the embedded triglycine sulfate crystallites. An additional peak in the temperature-dependent profiles of dielectric permittivity is detected at lower temperatures in freshly prepared samples of the considered composite; we associate it with the presence of residual water in these samples.

Though the primitive malignant tumors of the pleura have been identified in the years 1890, it is only in 1960 that Wagner and his team have published a study of 33 cases of mesothelioma in South Africa, attributed to crocidolite exposure for mines workers and their family. This publication went five years after the demonstration by Richard Doll in Great Britain of epidemiology relations between lungs cancer and professional exposure to asbestos dusts. Later, the research were on the type of asbestos fibers at the origin of the mesothelioma. The power of the chrysotile to induce this tumor among human beings was the object of controversy. but it is clear that the exposure to three kinds of amphibole asbestos (crocidolite, tremolite and anthophyllite) is responsible of the most important incidence of this cancer, even after low concentrations exposures.

Full Text Available Friedrich Nietzsche, one of the most influential and thoughtful philosopher in the 19th century, in an attempt to reassess values, finds himself in confrontation with accepted ideas of the modern world. Therefore, in his critical review, in order to reform and revive the modern civilization and culture, he writes his first book, i.e. The Birth of Tragedy. His various intentions in this book are as following: a cultural concerns and saving the culture of his age from nihilism and the danger of falling apart, b reassessing values, c showing the opposition of Christianity and conceptual philosophy of Socrates with the nature of life, Dionysus element as well as the desire to live, d aesthetic interpretation of living and being and e viewing life from the perspective of art. Nietzsche considers the last two cases as the special features of Greek's tragic art and praises Greek's tragic age for such perspective. He admires ancient Greeks as well as their culture and thought because they are the creators of tragic art and through such creation as well as by considering Dionysus element they accepted life with all of its good and bad aspects. Nietzsche discusses two fundamental concepts of birth and death of tragedy as well.

The present work reports the synthesis and characterization of the ilmenite-type rhombohedral structured CoTiO{sub 3} ceramic. The polycrystalline powder of CoTiO{sub 3} was prepared by the mixed-oxide technique. X-ray structural analysis of the compound confirmed the formation of a single-phase compound. The study of microstructure by scanning electron microscopy shows that the compound has well defined grains which are distributed uniformly throughout the surface. It shows that the grain size lies in the range of 8–10 μm. The Fourier transform infrared spectroscopy (FTIR) studies confirm the presence of Ti−O, Ti−O−Ti, Ti−O−O, Co−O bond in the studied compound. The frequency dependence of dielectric constant was explained on the basis of Maxwell–Wagner mechanism and Koop's phenomenological theory. The frequency-temperature dependence of impedance analysis shows that the bulk effect dominates up to 250 °C, and the appearance of second semicircular arc above 280 °C indicates the presence of grain boundary effect in the sample. The depressed semicircles in Nyquist plot with depression angles clearly indicate the distribution of relaxation times in the ceramic samples. It also shows that the material has negative temperature co-efficient of resistance similar to that of semiconductors. Similar behavior has also been observed in the study of I−V characteristics of the material. Through the study of dc conductivity of CoTiO{sub 3} and using the relation; ln σ{sub dc} α E{sub a}/K{sub B}T, activation energy of the compound was calculated. The frequency dependence of ac conductivity is explained on the basis of Correlated barrier Hopping Model. - Highlights: • The lattice parameters of CoTiO{sub 3} were determined by using Rietveld refinement method. • The frequency dependence of ε{sub r} was explained on the basis of Maxwell–Wagner model. • The depressed semicircles in Nyquist plot indicate the Non Debye-type response. • The

2016-12-01

During the last decades, the usage of spectral induced polarization (SIP) measurements in hydrogeology and detecting environmental problems has been extensively increased. However, the physical mechanisms which are responsible for the induced polarization response over the usual frequency range (typically 1 mHz to 10-20 kHz) require better understanding. The phase shift observed at high frequencies is sometimes attributed to the so-called Maxwell-Wagner polarization which takes place when charges cross an interface. However, SIP measurements of tap water show a phase shift at frequencies higher than 1 kHz, where no Maxwell-Wagner polarization may occur. In this paper, we enlighten the possible origin of this phase shift and deduce its likely relationship with the types of the measuring electrodes. SIP Laboratory measurements of tap water using different types of measuring electrodes (polarizable and non-polarizable electrodes) are carried out to detect the origin of the phase shift at high frequencies and the influence of the measuring electrodes types on the observed complex resistivity. Sodium chloride is used to change the conductivity of the medium in order to quantify the solution conductivity role. The results of these measurements are clearly showing the impact of the measuring electrodes type on the measured phase spectrum while the influence on the amplitude spectrum is negligible. The phenomenon appearing on the phase spectrum at high frequency (> 1 kHz) whatever the electrode type is, the phase shows an increase compared to the theoretical response, and the discrepancy (at least in absolute value) increases with frequency, but it is less severe when medium conductivity is larger. Additionally, the frequency corner is shifted upward in frequency. The dependence of this phenomenon on the conductivity and the measuring electrodes type (electrode-electrolyte interface) seems to be due to some dielectric effects (as an electrical double layer of small

Full Text Available The effect of thermal and electrical histories on structure and dielectric behaviors is studied using 0.95(Bi0.5Na0.50.97(Li0.5Nd0.50.03TiO3-0.05BaTiO3 (abbreviated as BNTLN0.03-BT5 ceramic as a selected system. Subtle structure change caused by annealing treatment, and pronounced phase transition and domain switching by electrical poling, are observed to occur, respectively. The dielectric constant and its strong frequency dispersion in unpoled samples decrease evidently by electrical poling due to electric field-induced ordered domain. The high temperature Maxwell-Wagner relaxor behavior vanishes by annealing treatment due to the loss of electrical inhomogeneity with interface charging effects. Piezoelectric properties are improved evidently by annealing treatment at 900 °C, implying a new appropriate method to improve piezoelectric properties.

Mandal, Amrita; Mitra, Sreemanta; Datta, Anindya; Banerjee, Sourish; Chakravorty, Dipankar

2012-04-01

CdS nanosheets of thickness 0.6 nm were grown within the interlayer spaces of Na-4 mica. Magnetization measurements carried out in the temperature range 2-300 K showed the composites to have weak ferromagnetic-like properties even at room temperature. The saturation magnetization (MS) at room temperature was found to be higher than that reported for CdS nanoparticles. The higher value of MS may be ascribed to the presence of a large number defects in the present CdS system, due to a large surface to volume ratio in the nanosheets as compared to that of CdS nanoparticles. The nanocomposites exhibited a magnetodielectric effect with a dielectric constant change of 5.3% for a magnetic field of 0.5 T. This occurred due to a combination of magnetoresistance and Maxwell-Wagner effect as delineated in the model developed by Catalan.

Temperature-touch interaction: Weber's phenomenon revisited.

Stevens, J C; Green, B G

1978-09-01

The six experiments reported here stemmed from Weber's (E. H. Weber, In R. Wagner (Ed.), Handwnörterbuch der Physiologie, 1846. Vol. 3, pp. 481-588) report that cold objects on the forehead feel heavier than warm ones, implying an effect of temperature on the touch modality. The experiments arrived at first-order answers to how temperature, force of stimulation, areal size of stimulation, and body locus might influence the magnitude of touch sensation. Typically, concomitant cooling greatly intensifies touch magnitude as perceived via the forehead and the forearm. Warning has little or no effect via the forehead but gives a significant intensification (less pronounced than that of cooling) on the forearm. When the areal size of the stimulation becomes very small, the intensification effects cannot be reliably demonstrated. The findings are reviewed in the light of what is known about the physiology of the cutaneous nerves.

Barros, João Paulo Pereira; Ximenes, Verônica Morais

2016-01-01

In this article we discuss the historical and theoretical-methodological aspects of the Community Psychology that has been developed in the state of Ceará, in northeastern Brazil, based on the praxis initiated by Professor Cezar Wagner de Lima Góis and further developed by the Community Psychology Nucleus (NUCOM) at the Federal University of Ceará. Important aspects of the beginning of this Community Psychology are presented, highlighting its academic and social perspectives. NUCOM is a space for the development of teaching, research, and outreach activities, which allows the systematization and deepening of this proposal for a different Community Psychology. Community Psychology is constituted by five theoretical-methodological marks: Popular Education, Biodance, Carl Rogers' Humanistic Approach, Cultural-Historical Psychology, and Liberation Psychology. Finally, the article describes the methods comprising this proposal for working in communities, which are sustained by pillars such as participation and problematizing dialogue.

The role of ocean phenomenon in music compositions

Liu, Chi-Min

2016-04-01

This is a preliminarily interdisciplinary study for exploring the elements of ocean phenomenon appearing in some compositions of classical music. The so-called ocean phenomenon contain wave conditions, climate change, coastal landform, and other natural events around or over the sea. In some music compositions, it is apparent that natural phenomenon over the sea influence the composers' moods and the music pieces they composed. In this poster, some music compositions in the 19th and the early 20th centuries will be introduced to demonstrate the relation between ocean and music works. These works include Meeresstille by Schubert, Étude Op.25 No.12 by Chopin, Fingal's Cave Overture by Mendelssohn, Der Fliegende Holländer by Wagner and La Mer by Debussy. In addition, present idea may give a novel way for music teachers to elucidate the knowledge of ocean science in classes.

2011-01-01

The effects of sintering temperature on the structural and electrical transport properties of nanocrystalline zinc ferrites are reported. The zinc ferrites were prepared by WOWS sol-gel synthesis route. The prepared sample was sintered at temperatures 500 deg. C, 700 deg. C and 900 deg. C respectively for 2 h. X-ray Diffraction (XRD) technique was used to describe the structural properties. The crystallite size, lattice parameters and porosity of samples were measured from the analysis of XRD data. The average crystallite size for each sample was measured using the Scherrer formula by considering the most intense (3 1 1) peak. The dielectric constant (e), dielectric loss tangent (tan theta ) and AC electrical conductivity of nanocrystalline Zn ferrites are investigated as a function of frequency and sintering temperature. All the electrical properties are explained in accordance with MaxwellWagner model and Koops phenomenological theory. (author)

Implementation of technical systems into work practices can result in shifting the balance of power in terms of what is visible and what is hidden (Suchman 1994; Star & Strauss 1999) and in fundamentally changing the nature of work itself (Bannon 1994). Sometimes these changes can have...... unpredictable and even adverse effects on the stakeholders involved (Clement & Wagner 1995). ECSCW as a venue has not shied away from pointing out that there is politics to sociomaterial processes we observe and study (Bannon & Bødker 1997; Bjørn and Balka 2007). As work computerization begins to involve...... the digitization of work practices, however, more thorny political questions emerge. The workplace changes when the spheres of private life and work are blurred as sensors are attached to the employee in the workplace for tracking movement (Gorm & Shklovski 2016; Møller et al. 2017), when the workplace as a fixed...

Based on a thermodynamically consistent model for precipitation in gallium arsenide crystals including surface tension and bulk stresses by Dreyer and Duderstadt, we propose different mathematical models to describe the size evolution of liquid droplets in a crystalline solid. The first class of models treats the diffusion-controlled regime of interface motion, while the second class is concerned with the interface-controlled regime of interface motion. Our models take care of conservation of mass and substance. We consider homogenised models, where different length scales of the experimental situation have been exploited in order to simplify the equations. These homogenised models generalise the well-known Lifshitz-Slyozov-Wagner model for Ostwald ripening. Mean field models capture the main properties of our system and are well adapted for numerics and further analysis. Numerical evidence suggests in which case which one of the two regimes might be appropriate to the experimental situation. (orig.)

Cheng, Sanyin; Zhang, Li-Fang

2017-01-01

The authors explored how thinking styles relate to quality of university life among deaf or hard of hearing (DHH) and hearing university students in mainland China. The first of two studies affirmed the validity and reliability of a modified version of the Quality of University Life Measure (QULM; Sirgy, Grezskowiak, & Rahtz, 2007) among 833 university students (366 DHH, 467 hearing). The second investigated relationships between thinking styles and quality of university life; the Thinking Styles Inventory-Revised II (Sternberg, Wagner, & Zhang, 2007) and modified QULM were administered to 542 students (256 DHH, 286 hearing). Students scoring higher on Type I styles (i.e., more creativity-generating, less structured, cognitively more complex) tended toward greater satisfaction with university life; those scoring higher on Type II (i.e., more norm-favoring, more structured, cognitively more simplistic) tended toward less satisfaction. Contributions, limitations, and implications of the research are discussed.

Discrimination learning with variable stimulus 'salience'

Directory of Open Access Journals (Sweden)

Treviño Mario

2011-08-01

Full Text Available Abstract Background In nature, sensory stimuli are organized in heterogeneous combinations. Salient items from these combinations 'stand-out' from their surroundings and determine what and how we learn. Yet, the relationship between varying stimulus salience and discrimination learning remains unclear. Presentation of the hypothesis A rigorous formulation of the problem of discrimination learning should account for varying salience effects. We hypothesize that structural variations in the environment where the conditioned stimulus (CS is embedded will be a significant determinant of learning rate and retention level. Testing the hypothesis Using numerical simulations, we show how a modified version of the Rescorla-Wagner model, an influential theory of associative learning, predicts relevant interactions between varying salience and discrimination learning. Implications of the hypothesis If supported by empirical data, our model will help to interpret critical experiments addressing the relations between attention, discrimination and learning.

Ways of looking ahead: hierarchical planning in language production.

Science.gov (United States)

Lee, Eun-Kyung; Brown-Schmidt, Sarah; Watson, Duane G

2013-12-01

It is generally assumed that language production proceeds incrementally, with chunks of linguistic structure planned ahead of speech. Extensive research has examined the scope of language production and suggests that the size of planned chunks varies across contexts (Ferreira & Swets, 2002; Wagner & Jescheniak, 2010). By contrast, relatively little is known about the structure of advance planning, specifically whether planning proceeds incrementally according to the surface structure of the utterance, or whether speakers plan according to the hierarchical relationships between utterance elements. In two experiments, we examine the structure and scope of lexical planning in language production using a picture description task. Analyses of speech onset times and word durations show that speakers engage in hierarchical planning such that structurally dependent lexical items are planned together and that hierarchical planning occurs for both direct and indirect dependencies.

2018-05-01

In present work, 3% cerium doped SnO2 (Sn0.97Ce0.03O2) nanoparticles (NPs) have been synthesized by sol-gel method. The prepared sample has been characterized by using various techniques such as XRD, UV-visible absorption spectroscopy and LCR meter measurements. Structural Rietveld refinement of XRD data reveals that (Sn0.97Ce0.03O2) sample has a pure single phase tetragonal structure with space group (P42/mnm) without creating any impurity phase such as cerium oxide. UV-visible spectroscopy determines band gap value 3.47 eV for (Sn0.97Ce0.03O2) NPs using Tauc's relation. Dielectric constant and loss decreased with increase in frequency while ac conductivity was found to increase with increase in frequency. The observed dielectric results has been explained in the light of Maxwell-Wagner model.

Effect of leaf and soil contaminations on heavy metals content in spring wheat crops

Weber, R.; Hrynczuk, B.

2000-01-01

Glass house experiments were carried out in Wagner pots containing 6 kg of soil. The amounts were compared of Zn, Pb and Cd taken up by the crop of spring wheat from contamination introduced into the soil or upon leaves. The heavy metals were labelled with the radioactive isotopes 65 Zn, 210 Pb and 115 Cd. The experiment was performed as a series of independent analyses in four replications. The dynamics of the labelled heavy metals translocation from contaminations sprayed on the upper or bottom side of the flag leaf was also tested. The highest concentration of 65 Zn was found in the straw and gain of wheat. much higher amounts of the metals appeared to have been taken up by the plants from leaf contamination than from soil. The highest dynamics of translocation from leaves to other vegetative and generative organs of plants was that of zinc. (author)

Il teatro di lingua tedesca tra Restaurazione e Naturalismo

Directory of Open Access Journals (Sweden)

Rita Svandrlik

2014-12-01

Full Text Available This article outlines the development of nineteenth-century theatre from a sociological viewpoint, in particular, focusing on the coming of age of the Wiener Volkstheater under the direction of Raimund and Nestroy, as well as with the staging of works by playwrights as different from each other as Grabbe, Grillparzer and Büchner. All three of them, from different angles, tackled the historical genre as well as the problem of theatre seen in a new light. However, it was not their plays that were successful during the period of the Restoration but rather grand scale historical dramas on familiar themes by mostly forgotten playwrights, often translations and adaptations of French and Classical works. In the decades that followed the Revolution of 1848, in which fiction was the dominant literary genre, Hebbel renovated tragedy as form, whereas Wagner went on to reform theatre at all levels.

Understanding consumer response to service guarantees

International Nuclear Information System (INIS)

Taylor, E.L.; Cole, J.M.

1999-01-01

Whether the goal is customer loyalty to a competitive energy service provider or customer satisfaction with monopoly distribution services, service guarantees must be seen as one way a company can communicate with its customers about the relationship it has (or wants) with them. In short, service guarantees must be evaluated as part of a company's overall brand management strategy. To do this, a conceptual framework within which to develop and link models of service delivery and brand management is needed. This means seeing both as examples of inference management. In this article the authors first interpret findings from their research on utility service guarantees in light of the model of service delivery proposed by Smith, Bolton, and Wagner. The authors then situate this model within their own model of utility brand management. The resulting approach can be used by a utility to evaluate whether and how to adopt service guarantees as part of its overall branding strategy

Spin Hartree-Fock approach to studying quantum Heisenberg antiferromagnets in low dimensions

Science.gov (United States)

Werth, A.; Kopietz, P.; Tsyplyatyev, O.

2018-05-01

We construct a new mean-field theory for a quantum (spin-1/2) Heisenberg antiferromagnet in one (1D) and two (2D) dimensions using a Hartree-Fock decoupling of the four-point correlation functions. We show that the solution to the self-consistency equations based on two-point correlation functions does not produce any unphysical finite-temperature phase transition, in accord with the Mermin-Wagner theorem, unlike the common approach based on the mean-field equation for the order parameter. The next-neighbor spin-spin correlation functions, calculated within this approach, reproduce closely the strong renormalization by quantum fluctuations obtained via a Bethe ansatz in 1D and a small renormalization of the classical antiferromagnetic state in 2D. The heat capacity approximates with reasonable accuracy the full Bethe ansatz result at all temperatures in 1D. In 2D, we obtain a reduction of the peak height in the heat capacity at a finite temperature that is accessible by high-order 1 /T expansions.

Electrical conductivities and electronic conductivities of the samples were measured using four-probe impedance spectrometry, four-probe dc polarization and Hebb-Wagner polarization within the temperature range of 973-1173 K. The electrical conductivities in LSGMC5 and LSGMC8.5 increased with decreasing oxygen partial pressures especially in the high (>10 -5 atm) and low oxygen partial pressure regions (lanthanum gallate samples increased with increasing concentration of cobalt, suggesting that the concentration of cobalt should be optimized carefully to maintain a high electrical conductivity and close to 1 oxygen ion transference number.

Structural, mechanical and electrical characterization of epoxy-amine/carbon black nanonocomposites

Directory of Open Access Journals (Sweden)

2008-05-01

Full Text Available This work presents an insight into the effect of preparation procedure and the filler content on both electrical and mechanical properties of a nanocomposite system. For the preparation of the nanocomposites diglycidyl ether of bisphenol A (DGEBA was used with triethylenetetramine (TETA as a curing agent. As fillers carbon black (CB nanoparticles with size from 25 to 75 nm were used. The characterization was done using Dynamic Mechanical Analysis (DMA, Dielectric Relaxation Spectroscopy (DRS, Differential Scanning Calorimetry (DSC, Wide Angle X-ray Diffraction (WAXD and electrical conductivity measurements. The dependence of the dynamic mechanical and dielectric parameters (E′, E″, tanδ, ε', ε″, σ and Tg is associated with the filler content and is controlled by the employed curing conditions. An increase in electrical conductivity, which is observed at about 1% w/w of carbon black, indicates the creation of conducting paths and is associated with the Maxwell Wagner Sillars (MWS relaxation, probably due to the formation of aggregated microstructures in the bulk composite..

Modeling the in vivo case with in vitro nanotoxicity data.

Shelley, Michael L; Wagner, Andrew J; Hussain, Saber M; Bleckmann, Charles

As more in vitro nanotoxicity data appear in the literature, these findings must be translated to in vivo effects to define nanoparticle exposure risk. Physiologically based pharmacokinetic (PBPK) modeling has played a significant role in guiding and validating in vivo studies for molecular chemical exposure and can develop as a significant tool in guiding similar nanotoxicity studies. This study models the population dynamics of a single cell type within a specific tissue. It is the first attempt to model the in vitro effects of a nanoparticle exposure, in this case aluminum (80 nm) and its impact on a population of rat alveolar macrophages (Wagner et al. 2007, J. Phys. Chem. B 111:7353-7359). The model demonstrates how in vitro data can be used within a simulation setting of in vivo cell dynamics and suggests that PBPK models should be developed quickly to interpret nanotoxicity data, guide in vivo study design, and accelerate nanoparticle risk assessment.

A comparator-hypothesis account of biased contingency detection.

Vadillo, Miguel A; Barberia, Itxaso

2018-02-12

Our ability to detect statistical dependencies between different events in the environment is strongly biased by the number of coincidences between them. Even when there is no true covariation between a cue and an outcome, if the marginal probability of either of them is high, people tend to perceive some degree of statistical contingency between both events. The present paper explores the ability of the Comparator Hypothesis to explain the general pattern of results observed in this literature. Our simulations show that this model can account for the biasing effects of the marginal probabilities of cues and outcomes. Furthermore, the overall fit of the Comparator Hypothesis to a sample of experimental conditions from previous studies is comparable to that of the popular Rescorla-Wagner model. These results should encourage researchers to further explore and put to the test the predictions of the Comparator Hypothesis in the domain of biased contingency detection.

Functional groups in a single pteridosperm species: Variability and circumscription (Pennsylvanian, Nova Scotia, Canada)

Science.gov (United States)

Zodrow, E.L.; Mastalerz, Maria

2007-01-01

Multiple foliar specimens of the Late Pennsylvanian fossil pteridosperm [gymnosperm] Alethopteris zeilleri (Ragot) Wagner were collected from one restricted stratigraphical horizon in the Canadian Sydney Coalfield. Variability of functional-group distribution using FTIR technique was studied in compressions, adaxial versus abaxial cuticles, and in unseparated cuticles as a function of maceration time from 48 to 168??h. The results obtained document spectral variability that could be expected within specimens of one species. For example, CH2/CH3 and Al/ox ratios can differ by as much as 20% of the values. Moreover, the experiments performed confirm that by using a previously established maceration protocol, long maceration periods do not bias FTIR spectra in terms of oxygenation overprinting. The inference that this cuticle is robust, under the given diagenetic level, probably reflects a reassuring degree of chemical fidelity of the Pennsylvanian plant to support Carboniferous chemotaxonomic observations. ?? 2006 Elsevier B.V.

Luna, Rafael E

2013-01-01

We all want our research to have an impact and to be cited by others. There are thousands of research articles published in our respective fields. How do we get someone to read our publications? This book shows you how to put your Title and Abstract into a story, along with the rest of your manuscript. Your research will stand out in a sea of peer-review publications, since it will be forged into a Scientific Story. As a research fellow in the laboratory of Professor Gerhard Wagner at Harvard Medical School, Dr. Luna was collaborating with four other top-notch laboratories in an interdisciplinary research effort to understand the end of the scanning mechanism required for protein synthesis in cells. They were sitting on a mound of research data collected by the various laboratories with varying expertise. This super-collaboration consisted of Physicists, Biologists, Structural Biologists, Biochemists, Chemists, a Computer Scientist, and a Chemical Engineer. There was so much data; yet they struggled to fashio...

Putative inhibitory training of a stimulus makes it a facilitator: a within-subject comparison of visual and auditory stimuli in autoshaping.

Nakajima, S

2000-03-14

Pigeons were trained with the A+, AB-, ABC+, AD- and ADE+ task where each of stimulus A and stimulus compounds ABC and ADE signalled food (positive trials), and each of stimulus compounds AB and AD signalled no food (negative trials). Stimuli A, B, C and E were small visual figures localised on a response key, and stimulus D was a white noise. Stimulus B was more effective than D as an inhibitor of responding to A during the training. After the birds learned to respond exclusively on the positive trials, effects of B and D on responding to C and E, respectively, were tested by comparing C, BC, E and DE trials. Stimulus B continuously facilitated responding to C on the BC test trials, but D's facilitative effect was observed only on the first DE test trial. Stimulus B also facilitated responding to E on BE test trials. Implications for the Rescorla-Wagner elemental model and the Pearce configural model of Pavlovian conditioning were discussed.

Retrospective Revaluation: The Phenomenon and Its Theoretical Implications

Science.gov (United States)

Miller, Ralph R.; Witnauer, James E.

2015-01-01

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

ecco: An error correcting comparator theory.

Ghirlanda, Stefano

2018-03-08

Building on the work of Ralph Miller and coworkers (Miller and Matzel, 1988; Denniston et al., 2001; Stout and Miller, 2007), I propose a new formalization of the comparator hypothesis that seeks to overcome some shortcomings of existing formalizations. The new model, dubbed ecco for "Error-Correcting COmparisons," retains the comparator process and the learning of CS-CS associations based on contingency. ecco assumes, however, that learning of CS-US associations is driven by total error correction, as first introduced by Rescorla and Wagner (1972). I explore ecco's behavior in acquisition, compound conditioning, blocking, backward blocking, and unovershadowing. In these paradigms, ecco appears capable of avoiding the problems of current comparator models, such as the inability to solve some discriminations and some paradoxical effects of stimulus salience. At the same time, ecco exhibits the retrospective revaluation phenomena that are characteristic of comparator theory. Copyright © 2018 Elsevier B.V. All rights reserved.

Performance of a multipurpose research electrochemical reactor

Henquin, E.R.; Bisang, J.M.

2011-01-01

Highlights: → For this reactor configuration the current distribution is uniform. → For this reactor configuration with bipolar connection the leakage current is small. → The mass-transfer conditions are closely uniform along the electrode. → The fluidodynamic behaviour can be represented by the dispersion model. → This reactor represents a suitable device for laboratory trials. - Abstract: This paper reports on a multipurpose research electrochemical reactor with an innovative design feature, which is based on a filter press arrangement with inclined segmented electrodes and under a modular assembly. Under bipolar connection, the fraction of leakage current is lower than 4%, depending on the bipolar Wagner number, and the current distribution is closely uniform. When a turbulence promoter is used, the local mass-transfer coefficient shows a variation of ±10% with respect to its mean value. The fluidodynamics of the reactor responds to the dispersion model with a Peclet number higher than 10. It is concluded that this reactor is convenient for laboratory research.

Phaseout of nuclear energy in 2011. The 13th amendment to the Atomic Energy Law from the viewpoint of German constitutional law; Kernenergieausstieg 2011. Die 13. AtG-Novelle aus verfassungsrechtlicher Sicht

Di Fabio, Udo; Durner, Wolfgang; Wagner, Gerhard

2013-07-01

The present study analyses the framework provided by German constitutional law in regard to the nuclear energy phaseout in 2011, proceeding in three steps. The contribution by Udo di Fabio is dedicated to the question whether this decision, as well as the manner of its implementation, are in accord with the guarantee of ownership provided by Art. 14 of the German Basic Law (GG). Wolfgang Durner discusses implications of the principle of equality as set out in Art. 3 Section 1 GG in the field of nuclear law. The article by Gerhard Wagner departs from the premise that the restrictions on the use of nuclear power plants should not have been imposed without granting the operators due compensation. These findings are used a basis for determining the implications of fundamental rights for a compensation regime that is in accord with the German constitution. All three contributions originate from a legal expertise that was prepared by the three authors on behalf of the RWE stock company.

A dielectrophoresis-impedance method for protein detection and analysis

Directory of Open Access Journals (Sweden)

Ahmad Sabry Mohamad

2017-01-01

Full Text Available Dielectrophoresis (DEP has increasingly been used for the assessment of the electrical properties of molecular scale objects including proteins, DNA, nanotubes and nanowires. However, whilst techniques have been developed for the electrical characterisation of frequency-dependent DEP response, biomolecular study is usually limited to observation using fluorescent markers, limiting its applicability as a characterisation tool. In this paper we present a label-free, impedance-based method of characterisation applied to the determination of the electrical properties of colloidal protein molecules, specifically Bovine Serum Albumin (BSA. By monitoring the impedance between electrodes as proteins collect, it is shown to be possible to observe multi-dispersion behaviour. A DEP dispersion exhibited at 400 kHz is attributable to the orientational dispersion of the molecule, whilst a second, higher-frequency dispersion is attributed to a Maxwell-Wagner type dispersion; changes in behaviour with medium conductivity suggest that this is strongly influenced by the electrical double layer surrounding the molecule.

Optimization and modification of the method for detection of rhamnolipids

Takeshi Tabuchi

2015-10-01

Full Text Available Use of biosurfactants in bioremediation, facilitates and accelerates microbial degradation of hydrocarbons. CTAB/MB agar method created by Siegmund & Wagner for screening of rhamnolipids (RL producing strains, has been widely used but has not improved significantly for more than 20 years. To optimize the technique as a quantitative method, CTAB/MB agar plates were made and different variables were tested, like incubation time, cooling, CTAB concentration, methylene blue presence, wells diameter and inocula volume. Furthermore, a new method for RL detection within halos was developed: precipitation of RL with HCl, allows the formation a new halos pattern, easier to observe and to measure. This research reaffirm that this method is not totally suitable for a fine quantitative analysis, because of the difficulty to accurately correlate RL concentration and the area of the halos. RL diffusion does not seem to have a simple behavior and there are a lot of factors that affect RL migration rate.

Agrawal, Shraddha; Parveen, Azra; Azam, Ameer

2018-05-01

The Ca and Cr doped cobalt ferrite nanoparticles (Co0.8Ca0.2) (Fe0.8 Cr0.2)2O4 were synthesized by auto combustion method. Microstructural studies were carried out by X-ray diffraction (XRD). The crystalline size of synthesized nanoparticles as determined by the XRD was found to be 17.6 nm. These structural studies suggest that the crystal system remains spinal even with the doping of calcium and chromium. Optical properties of Ca and Cr doped cobalt ferrite were studied by UV-visible technique in the range of 200-800 nm. The energy band gap was calculated with the help of Tauc relationship. Ca and Cr doped cobalt ferrite annealed at 600°C exhibit significant dispersion in complex permeability. The dielectric constant and dielectric loss of cobalt ferrite were studied as a function of frequency and were explained on the basis of Koop's theory based on Maxwell Wagner two layer models and electron hopping.

Depressive realism and the effect of intertrial interval on judgements of zero, positive, and negative contingencies.

Science.gov (United States)

Msetfi, Rachel M; Murphy, Robin A; Simpson, Jane

2007-03-01

In three experiments we tested how the spacing of trials during acquisition of zero, positive, and negative response-outcome contingencies differentially affected depressed and nondepressed students' judgements. Experiment 1 found that nondepressed participants' judgements of zero contingencies increased with longer intertrial intervals (ITIs) but not simply longer procedure durations. Depressed groups' judgements were not sensitive to either manipulation, producing an effect known as depressive realism only with long ITIs. Experiments 2 and 3 tested predictions of Cheng's (1997) Power PC theory and the Rescorla-Wagner (1972) model, that the increase in context exposure experienced during the ITI might influence judgements most with negative contingencies and least with positive contingencies. Results suggested that depressed people were less sensitive to differences in contingency and contextual exposure. We propose that a context-processing difference between depressed and nondepressed people removes any objective notion of "realism" that was originally employed to explain the depressive realism effect (Alloy & Abramson, 1979).

Understanding consumer response to service guarantees

Energy Technology Data Exchange (ETDEWEB)

Taylor, E.L.; Cole, J.M.

1999-10-01

Whether the goal is customer loyalty to a competitive energy service provider or customer satisfaction with monopoly distribution services, service guarantees must be seen as one way a company can communicate with its customers about the relationship it has (or wants) with them. In short, service guarantees must be evaluated as part of a company's overall brand management strategy. To do this, a conceptual framework within which to develop and link models of service delivery and brand management is needed. This means seeing both as examples of inference management. In this article the authors first interpret findings from their research on utility service guarantees in light of the model of service delivery proposed by Smith, Bolton, and Wagner. The authors then situate this model within their own model of utility brand management. The resulting approach can be used by a utility to evaluate whether and how to adopt service guarantees as part of its overall branding strategy.

The saturated vapor pressures of 1,1,1,2-tetrafluoroethane (R134a) and propane (R290), and the (vapor + liquid) equilibrium (VLE) data at (255.000, 265.000, 275.000, and 285.000) K for the (R134a + R290) system were measured by a recirculation apparatus with view windows. The uncertainty of the temperatures, pressures, and compositions are less than {+-}5 mK, {+-}0.0005 MPa, and {+-}0.005, respectively. The saturated vapor pressures data were correlated by a Wagner type equation and compared with the reference data. The binary VLE data were correlated with the Peng-Robinson equation of state (PR EoS) incorporating the Huron-Vidal (HV) mixing rule utilizing the nonrandom two-liquid (NRTL) activity coefficient model. For mixtures, the maximum average absolute relative deviation of pressure is 0.15%, while the maximum average absolute deviation of vapor phase mole fraction is 0.0045. Azeotropic behavior can be found for the (R134a + R290) system at measured temperatures.

Magnetodielectric behaviour in La0.53Ca0.47MnO3

Pandey, Suchita; Kumar, Jitender; Awasthi, A M

2014-01-01

We explore magneto-dielectricity in La 0.53 Ca 0.47 MnO 3 across its paramagnetic (PMI) to ferromagnetic (FMM) isostructural transition at T C  ∼ 253 K, by magnetic (M), caloric (W), dielectric (ε′), magnetoresistive (MR), and magnetocapacitance (MC) investigations. A skew-broadened first-order transition character is confirmed via heating/cooling hystereses in M(T) and W(T), with a superheating temperature T ** next to T C and supercooling temperature T * exhibiting kinetics. Above T C , linearly related MC and MR reflect purely a magnetoresistance effect. Near T C , the high-frequency MC (5 Tesla (T)), far exceeds the magneto-losses, and is uncorrelated with dc MR (5 T) in the FM-ordered state. The intrinsic magneto-dielectricity manifest below T C and above ∼kHz is traced to an intra-granular Maxwell–Wagner-type effect at the interface region of PMI–FMM phase coexistence. (paper)

Factors Influencing Parents' Preferences and Parents' Perceptions of Child Preferences of Picturebooks

Wagner, Laura

2017-01-01

This study examined factors influencing parents' preferences and their perceptions of their children's preferences for picturebooks. First, a content analysis was conducted on a set of picturebooks (N = 87) drawn from the sample described in Wagner (2013); Then, parents (N = 149) rated the books and several content properties were examined for their ability to predict parents' preferences and their perception of their children's preferences. The initial content analysis found correlated clusters of disparate measures of complexity (linguistic, cognitive, narrative) and identified a distinctive sub-genre of modern books featuring female protagonists. The experimental preference analysis found that parents' own preferences were most influenced by the books' age and status; parents' perceptions of their children's preferences were influenced by gender, with parents perceiving their sons (but not daughters) as dis-preferring books with female protagnoists. In addition, influences of the child's reading ability and the linguistic complexity of the book on preferences suggested a sensitivity to the cultural practice of joint book-reading. PMID:28919869

Room-temperature multiferroic and magnetocapacitance effects in M-type hexaferrite BaFe{sub 10.2}Sc{sub 1.8}O{sub 19}

The room-temperature multiferroic and magnetocapacitance (MC) effects of polycrystalline M-type hexaferrite BaFe{sub 10.2}Sc{sub 1.8}O{sub 19} have been investigated. The results show that the magnetic moments of insulating BaFe{sub 10.2}Sc{sub 1.8}O{sub 19} can be manipulated by the electric field at room temperature, indicating the existence of magnetoelectric coupling. Moreover, large MC effects are also observed around the room temperature. A frequency dependence analysis shows that the Maxwell-Wagner type magnetoresistance effect is the dominant mechanism for MC effects at low frequencies. Both the magnetoelectric-type and non-magnetoelectric-type spin-phonon couplings contribute to the MC effects at high frequencies with the former being the dominant mechanism. The above results show that the hexaferrite BaFe{sub 10.2}Sc{sub 1.8}O{sub 19} is a room-temperature multiferroic material that can be potentially used in magnetoelectric devices.

The Historical Development of Immunoendocrine Concepts of Psychiatric Disorders and Their Therapy

Science.gov (United States)

Steinberg, Holger; Kirkby, Kenneth C.; Himmerich, Hubertus

2015-01-01

Relationships between the central nervous, immune and endocrine systems are a focus of psychiatric research, particularly in depression and schizophrenia. The field has long antecedents. Observed phenomena attributable to these relationships date back to the Neolithic era. Immunoendocrine theories in the broadest sense are recorded in antiquity. In the 19th century, Kraepelin and Wagner-Jauregg reported pioneering clinical observations in psychiatric patients. Von Basedow, Addison and Cushing described psychiatric symptoms in patients suffering from endocrine diseases. The 20th century opened with the identification of hormones, the first, adrenaline, chemically isolated independently by Aldrich und Takamine in 1901. Berson and Yalow developed the radioimmunoassay (RIA) technique in 1959 making it possible to measure levels of hormones and cytokines. These developments have enabled great strides in psychoimmunoendocrinology. Contemporary research is investigating diagnostic and therapeutic applications of these concepts, for example by identifying biomarkers within the endocrine and immune systems and by synthesizing and testing drugs that modulate these systems and show antidepressant or antipsychotic properties.

1987-01-01

Recently I taught short courses on functional equations at several universities (Barcelona, Bern, Graz, Hamburg, Milan, Waterloo). My aim was to introduce the most important equations and methods of solution through actual (not artifi­ cial) applications which were recent and with which I had something to do. Most of them happened to be related to the social or behavioral sciences. All were originally answers to questions posed by specialists in the respective applied fields. Here I give a somewhat extended version of these lectures, with more recent results and applications included. As previous knowledge just the basic facts of calculus and algebra are supposed. Parts where somewhat more (measure theory) is needed and sketches of lengthier calcula­ tions are set in fine print. I am grateful to Drs. J. Baker (Waterloo, Ont.), W. Forg-Rob (Innsbruck, Austria) and C. Wagner (Knoxville, Tenn.) for critical remarks and to Mrs. Brenda Law for care­ ful computer-typing of the manuscript (in several versions). A...

The Efficacy of Jing Wan Hong Ointment for Nerve Injury Diabetic Foot Ulcer and Its Mechanisms

Directory of Open Access Journals (Sweden)

Shumei Jin

2014-01-01

Full Text Available Jing Wan Hong ointment contains 30 kinds of Chinese herbs, with functions of activating blood circulation to disperse blood stasis, clearing heat, eliminating dampness, and reducing swelling by detoxification. Therefore, Jing Wan Hong ointment may facilitate the healing of ulcers. The aim of this study was to evaluate the efficacy and mechanisms of Jing Wan Hong ointment for healing diabetic foot ulceration in Wistar rats induced by streptozotocin and sciatic nerve damage. The results showed that Jing Wan Hong ointment had a marked effect on foot ulcers in diabetic rats induced by initial nerve injury. These effects were manifested by reducing the foot ulcer size and Wagner grade after seven days of treatment. The diabetic rats with foot ulcers were almost healed after 21 days of treatment. Moreover, the mechanisms of this effect seem to be dependent on increased expression of PDGF mRNA, but there was no influence on the expression of TGF-β, VEGF, and FLT-1 mRNA.

Phase decomposition in a mechanically alloyed Cu-44.5 at%Ni-22.5 at%Fe alloy during isothermal aging

2006-01-01

A supersaturated solid solution of Cu-44.5 at%Ni-22.5 at%Fe alloy was produced by ball milling of a pure chemical elemental mixture for 1080 ks. An fcc supersaturated solid solution with a grain size of about 20 nm was obtained after milling. This alloy was subsequently aged at 803, 898 and 1003 K for different times. The growth kinetics of the modulation wavelength was determined from the X-ray diffraction results and followed the Lifshitz-Slyozov-Wagner theory for a diffusion-controlled coarsening in the MA alloy after aging. The growth kinetics of composition modulation wavelength for the MA alloy was faster at 803 and 898 K than that for the same alloy composition obtained by a conventional processing and then aged at the same temperatures. The activation energy for the decomposed phase coarsening process in the MA alloy was lower than that corresponding to the conventionally-processed alloy. (author)

Some thermodynamic properties of hydrogen chloride and deuterium chloride

The molar volume of HCl has been measured from 162 to 236 K, and of DCl from 160 to 218 K. Direct measurements of the vapour pressure of HCl have been made from 159 to 220 K, and of DCl from 158 to 188 K. In addition, the difference in the vapour pressure of the two isotopic forms has been measured from 159 to 226 K. At lower temperatures, the vapour pressure of HCl exceeds that of DCl but above 223.35 K that position is reversed. The vapour pressure of each substance has been fitted to a Wagner equation. These equations have been used in conjunction with the Clapeyron equation to calculate the molar enthalpies of vaporization. If r is the ratio of the vapour pressure of HCl to that of DCl, the values of r conform very closely to the equation T ln r = - A + C/T, where A and C are constants.

The theories of V. V. Wagner (1908-1981) on abstractions of systems of binary relations are presented here within their historical and mathematical contexts. This book contains the first translation from Russian into English of a selection of Wagner’s papers, the ideas of which are connected to present-day mathematical research. Along with a translation of Wagner’s main work in this area, his 1953 paper ‘Theory of generalised heaps and generalised groups,’ the book also includes translations of three short precursor articles that provide additional context for his major work. Researchers and students interested in both algebra (in particular, heaps, semiheaps, generalised heaps, semigroups, and groups) and differential geometry will benefit from the techniques offered by these translations, owing to the natural connections between generalised heaps and generalised groups, and the role played by these concepts in differential geometry. This book gives examples from present-day mathematics where ideas r...

Full Text Available Probing into the school culture is the first step for the enhancement of the effectiveness of any school. Conducted in an English-medium private university in Turkey, this study aims at exploring teachers’ perceptions of existing school culture to provide enriched and contemporary understandings of that culture, as well as making implications regarding understanding and improving school culture. Quantitative data was collected using the School Culture Survey (SCS developed by Gruenert and Valentine, and the School Culture Triage, developed by Wagner and Masden-Copas; and qualitative data was collected through semi-structured interviews conducted with a sample group of teachers from the school. The results suggest that three dominant aspects of the culture of the school studied are collegial support and collaboration, collaborative leadership and unity of purpose. The outcomes of this research study facilitate a ‘personal critique’ for the given school, and implications can be extended to institutions operating in similar settings
