    Full Text Available The topic of this paper is one aspect of the relationship between Serbia and Byzantium at the beginning of the 15th Century, during the so-called "despot period" of the reign of Stefan Lazarević (1402-1427, namely the fate of the Byzantine title of Despots' in Serbia against the background of the political situation in the Balkans at the time of Turkish domination. Knez Stefan (1377-1427, Knez Lazar's son, received the title of Despotes according to the procedure long ago established at the Byzantine Court. In Byzantium, this title, which was second in rank only to the title of the Emperor, used to be endowed to the relatives of the imperial dynasty, it was not hereditary and did not depend on the territory ruled by the bearer of the title. It was a personal court title of the highest rank in Byzantium. This honor was bestowed upon the young Knez Stefan in summer of 1402 after his return from the battlefield of Angora (Ankara, where Sultan Beyazid I suffered a disastrous defeat from the hands of the Tatars. The Serbian Knez was solemnly received in Constantinople, a marriage between himself and a sister of the Byzantine Empress was arranged and John VII Palaeologus, the co-regent of the then-absent Emperor Manuel II Palaeologus, endowed him with the title of Despotes. Knez Stefan carried this title till the end of his life. It was held in great honors in Serbia and was broadened in meaning to designate a ruler's title in general, remaining alive among the Serbs even after the fall of the Byzantine Empire. Stefan Lazarević received the dignity of a Despotes once more, in 1410 in Constantinople. All this notwithstanding, the political situation in the South-East of Europe at the beginning of the 15th Century was all but favorable. Some Christian states were conquered by the Turks (Bulgaria, some were vassals of the Sultan (Byzantium, Serbia. Everything depended on the Ottomans.

  8. The 'Byzantinisms' of king Stefan Radoslav

    Directory of Open Access Journals (Sweden)

    Maksimović Ljubomir

    2009-01-01

    Full Text Available The life-style and politics of Stefan Radoslav bear the mark of activities that indicated his special attachment to the Byzantine world. These activities were prompted by a combination of ideological ambitions and political reality, but they were not in keeping with the modest achievements of Radoslav's reign. Moreover, most of these activities belong to the time when Radoslav was heir to the throne. There is no doubt that Stefan Nemanjić the Grand Zhupan and subsequently the first crowned king, had exclusive connections with the Byzantine dynasty of the Angeloi, especially with the emperor Alexios III (1195-1203. In that context, the donor's inscription in the basic ring of the dome in the Church of the Mother of God in Studenica (1208, in which his father Stefan Nemanja, is mentioned as (former 'veleslavni gospodin vse srbske zemlje veli(ki župan i svat cara grčkog kir Alesija', is quite indicative. This ideological construction would acquire a contour in reality by means of a political marriage with one of the female offspring of Angeloi lineage, which would represent an alternative solution to Stefan's failed marriage with Eudocia, daughter of the emperor Alexios. Instead, several years elapsed in waging war with the Latins, the Bulgarians and the State of Epiros. However, efforts to create firmer, more tangible ties with the Angeloi dynasty from Epiros were not forgotten. Therefore, the Serbian monarch brought his eldest son Radoslav into play, intending to have him act as a link with the Angeloi bloodline. As a result of all this, the final attempt to have Radoslav become the husband of a princess from the Angelos dynasty is not surprising. At the end of 1219 or the beginning of 1220, he married Anna Doukaina, the daughter of the epirotic ruler Theodore I Angelos Doukas Komnenos, which at that point represented a marriage connection of the highest possible level between two ruling houses. Stefan's insistence on Serbia acquiring a stake

    This volume emphasises studies related toclassical Stefan problems. The term "Stefan problem" isgenerally used for heat transfer problems with phase-changes suchas from the liquid to the solid. Stefan problems have somecharacteristics that are typical of them, but certain problemsarising in fields such as mathematical physics and engineeringalso exhibit characteristics similar to them. The term``classical" distinguishes the formulation of these problems fromtheir weak formulation, in which the solution need not possessclassical derivatives. Under suitable assumptions, a weak solutioncould be as good as a classical solution. In hyperbolic Stefanproblems, the characteristic features of Stefan problems arepresent but unlike in Stefan problems, discontinuous solutions areallowed because of the hyperbolic nature of the heat equation. Thenumerical solutions of inverse Stefan problems, and the analysis ofdirect Stefan problems are so integrated that it is difficult todiscuss one without referring to the other. So no...

The analysis is based on a semiotic approach, compared with the knowledge provided by literary criticism. As a result of this, the paper tries to cast a new light on Zweig’s place in literature. In particular, his progressive view on peace avoids the risks related to every kind of “professional reformism” and thus is still interesting nowadays.

  19. Berroia in Stefan Dušan's politics

    Directory of Open Access Journals (Sweden)

    Maksimović Ljubomir M.

    2004-01-01

    Full Text Available Being one of the most important cities in Macedonia, Berroia automatically entered the horizon of Serbian politics once Stefan Dušan got involved into the Byzantine Civil War during the forties of the fourteenth century. The King's previous invasion of Macedonia, in the thirties, had been aimed directly towards Thessalonica and was a failure. Thus, in the second phase of his politics, in which Macedonia was used as a backing in the striving for the Empire, Thessalonica was temporarily left aside, although not before first Serres and then Berroia had been captured, so as to leave it completely isolated. Initially, it was Serres rather than Berroia that Dušan was focused on, its conquest in September 1345 leading immediately to the proclamation of the Empire. Afterwards — in the first half of 1346 — Berroia was also conquered and turned into an important Serbian stronghold, Thessalonica being thus cut off, which enabled the Serbs to await a more favorable time to capture it. At the same time, the conquest of Berroia paved the way for the Serbian invasion of Epirus and Thessalia. Emperor John VI Cantacuzenus was certainly aware of the consequences of such a strategic constellation. Thus, when he finally managed to neutralize the Zelots in Thessalonica, his first move towards the change of the situation was to recuperate Berroia and surrounding towns. This was such a severe blow for the Serbs, that it immediately became clear that even Dušan's imperial power might be endangered if his position in Macedonia further weakened. He reacted promptly and recaptured Berroia and other strongholds he had lost. The conquest of Berroia was lead by the nobleman Radoslav Hlapen, who first acted as a governor on behalf of Dušan, and after the death of the Emperor practically as an independent ruler of that part of Macedonia.

  20. Electrical Discharge Platinum Machining Optimization Using Stefan Problem Solutions

    Directory of Open Access Journals (Sweden)

    I. B. Stavitskiy

    2015-01-01

    Full Text Available The article presents the theoretical study results of platinum workability by electrical discharge machining (EDM, based on the solution of the thermal problem of moving the boundary of material change phase, i.e. Stefan problem. The problem solution enables defining the surface melt penetration of the material under the heat flow proceeding from the time of its action and the physical properties of the processed material. To determine the rational EDM operating conditions of platinum the article suggests relating its workability with machinability of materials, for which the rational EDM operating conditions are, currently, defined. It is shown that at low densities of the heat flow corresponding to the finishing EDM operating conditions, the processing conditions used for steel 45 are appropriate for platinum machining; with EDM at higher heat flow densities (e.g. 50 GW / m2 for this purpose copper processing conditions are used; at the high heat flow densities corresponding to heavy roughing EDM it is reasonable to use tungsten processing conditions. The article also represents how the minimum width of the current pulses, at which platinum starts melting and, accordingly, the EDM process becomes possible, depends on the heat flow density. It is shown that the processing of platinum is expedient at a pulse width corresponding to the values, called the effective pulse width. Exceeding these values does not lead to a substantial increase in removal of material per pulse, but considerably reduces the maximum repetition rate and therefore, the EDM capacity. The paper shows the effective pulse width versus the heat flow density. It also presents the dependences of the maximum platinum surface melt penetration and the corresponding pulse width on the heat flow density. Results obtained using solutions of the Stephen heat problem can be used to optimize EDM operating conditions of platinum machining.

  1. Approximate Analytic Solutions for the Two-Phase Stefan Problem Using the Adomian Decomposition Method

    Directory of Open Access Journals (Sweden)

    Xiao-Ying Qin

    2014-01-01

    Full Text Available An Adomian decomposition method (ADM is applied to solve a two-phase Stefan problem that describes the pure metal solidification process. In contrast to traditional analytical methods, ADM avoids complex mathematical derivations and does not require coordinate transformation for elimination of the unknown moving boundary. Based on polynomial approximations for some known and unknown boundary functions, approximate analytic solutions for the model with undetermined coefficients are obtained using ADM. Substitution of these expressions into other equations and boundary conditions of the model generates some function identities with the undetermined coefficients. By determining these coefficients, approximate analytic solutions for the model are obtained. A concrete example of the solution shows that this method can easily be implemented in MATLAB and has a fast convergence rate. This is an efficient method for finding approximate analytic solutions for the Stefan and the inverse Stefan problems.

  5. The multiple meanings of the Stefan-number (and relatives) in refrigeration

    Energy Technology Data Exchange (ETDEWEB)

    Ziegler, F. [Technische Universitaet Berlin, Institut fuer Energietechnik, KT 2, Marchstrasse 18, D-10587 Berlin (Germany)

    2010-11-15

    The Stefan-number is one out of the multitude of dimensionless numbers which predominantly are used in chemical engineering or heat and mass transfer problems. It relates sensible heat to latent heat and is a key number in solving the problem of heat transfer during solidification or melting. However, numbers similar to this show up also when several thermodynamic problems or relationships in refrigeration engineering are analyzed. Using the Stefan-number it can be distinguished if a refrigerant superheats or condenses during compression, it gives the size of the throttling loss, and it helps to decide if a suction line heat exchanger is beneficial or not. For absorption heat pumping, it allows to quantify the most important loss mechanism, the solution heat exchanger loss. Of course, all this information can be acquired in different ways - and maybe in more precise ways - also, but at least for teaching the basics of refrigeration the Stefan-number is simple to use and very easy to understand. In this paper, the different ways of how to use the Stefan-number in teaching and understanding thermodynamics of refrigerants are presented. (author)

  6. Entering of Stefan Dušan into the Empire

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available At the moment when, in October 1341, a new Civil War broke out in the Byzantium after the death of Andronicus III, the traditional views of the imperial power and the Empire underwent considerable changes. The powers of the co-rulers had been on the rise since 1272, and during the Civil War of 1321-1328 the Byzantine Empire was in effect divided, that is, two Basileis were ruling 'imperially' (autokratorikōs over their respective territories within the formally unified Empire, under the scope of relations of Superior basileus - co-basileus. Therefore, the Empire (autokratoria, imperium could multiply in the sense of rulers’ authorities, and be divided in the sense of territoriality. The imperial power and the Empire became subject to family relations and family law. In view of the family connections between the Byzantine Emperors (basileis autokratores and the monarchs of the neighboring countries and nations, the right to succession was being used as an argument in some disputes between the rulers. The Byzantine law, that is the Byzantine political views, allowed for the possibility of the so-called 'joint rule' (e oikeia arch by a Byzantine basileus autokrator and some other, foreign member of the dynasty ruling over certain region of the Byzantine Empire - a foreign ruler would be allowed to rule on condition that the Byzantine basileus be recognized as the supreme master. This scenario is known from one recorded dispute between the Byzantine basileus Andronicus III and the Bulgarian tsar Michael Assen III dating from 1328, when the Bulgarian Emperor did not accept the Byzantine rule, however. All these circumstances are of special importance since they directly precede the King Stefan Dušan’s involvement in the Civil War, that is, his later entering into the Empire. The first phase of Dušan’s involvement in the Civil War is typically conquering and opportunistic in nature, with the aim of immediate territorial enlargement. The

  10. A comparison of Fick and Maxwell-Stefan diffusion formulations in PEMFC gas diffusion layers

    Science.gov (United States)

    Lindstrom, Michael; Wetton, Brian

    2017-01-01

    This paper explores the mathematical formulations of Fick and Maxwell-Stefan diffusion in the context of polymer electrolyte membrane fuel cell cathode gas diffusion layers. The simple Fick law with a diagonal diffusion matrix is an approximation of Maxwell-Stefan. Formulations of diffusion combined with mass-averaged Darcy flow are considered for three component gases. For this application, the formulations can be compared computationally in a simple, one dimensional setting. Despite the models' seemingly different structure, it is observed that the predictions of the formulations are very similar on the cathode when air is used as oxidant. The two formulations give quite different results when the Nitrogen in the air oxidant is replaced by helium (this is often done as a diagnostic for fuel cells designs). The two formulations also give quite different results for the anode with a dilute Hydrogen stream. These results give direction to when Maxwell-Stefan diffusion, which is more complicated to implement computationally in many codes, should be used in fuel cell simulations.

  11. Were king Stefan the First-Crowned and his son Radoslav co-rulers?

    Directory of Open Access Journals (Sweden)

    Bubalo Đorđe

    2009-01-01

    Full Text Available The Serbian historiography considers the issue of the co-ruling of King Stefan the First-Crowned and his son Radoslav as the one finally resolved. The suggested solution on the co-rule of Stefan and Radoslav may be most succinctly expressed as following: as early as in the year of 1220, due to the frail health of Stefan the First-Crowned and Radoslav's marriage to Anne the Epirus princess, Radoslav was crowned to be the king and positioned to co-rule with his father after the Byzantine model of governing. Nevertheless this point of view has some loose ends. The notion of co-ruling and the very term of 'co-ruler' are quite freely used in the scholarly works. A general consensus on the precise meaning has not been reached yet. At the point where one author perceives a co-rule, the other categorically denies it. Basically the approach equalizing the heir to the throne and the co-ruler is wrong. Although the co-rulers in most cases were the throne heirs, they cannot be called the co-rulers because of the right to inherit the throne, but for the ruling attributes that formally established that right. The conviction of the co-rule of King Stefan and his son Radoslav is founded on the interpretation of the facts coming from the following sources: entitling charters for the monastery of Žiča, produced by Stefan and Radoslav around 1220; some segments from St. Sava's biographies by Domentian and Theodosius describing the circumstances of Stefan's death-bed leaving the throne to Radoslav; the three acts of the town of Kotor from 1221 and 1227 dated by the rule of king Radoslav, the portraits of Stefan and Radoslav next to the entrance to the Church of the Ascension in the monastery of Žiča and in the nartex of the Mileševa monastery church. In the first Žiča charter, Stefan calls Radoslav his heir, while in the second Žiča charter Stefan points out Radoslav as his first-born son blessed by him to be the king of the whole state.

  12. New Fundamental Light Particle and Breakdown of Stefan-Boltzmann's Law

    Directory of Open Access Journals (Sweden)

    Samoilov V.

    2011-04-01

    Full Text Available Recently, we predicted the existence of fundamental particles in Nature, neutral Light Particles with spin 1 and rest mass m = 1.8 x 10^{-4} m_e, in addition to electrons, neutrons and protons. We call these particles Light Bosons because they create electromagnetic field which represents Planck's gas of massless photons together with a gas of Light Particles in the condensate. Such reasoning leads to a breakdown of Stefan-Boltzmann's law at low temperature. On the other hand, the existence of new fundamental neutral Light Particles leads to correction of such physical concepts as Bose-Einstein condensation of photons, polaritons and exciton polaritons.

The class of (1+3)-dimensional nonlinear BVPs of the Stefan type, modeling the process of melting and evaporation of metals, is studied in detail. Using the definition proposed, the group classification problem for this class of BVPs is solved and some reductions (with physical meaning) to BVPs of lower dimensionality are made. Examples of how to construct exact solutions of the (1+3)-dimensional nonlinear BVP with the correctly specified coefficients are presented.

  16. Stefan blowing effect on bioconvective flow of nanofluid over a solid rotating stretchable disk

    Directory of Open Access Journals (Sweden)

    N.A. Latiff

    2016-12-01

    Full Text Available A mathematical model for the unsteady forced convection over rotating stretchable disk in nanofluid containing micro-organisms and taking into account Stefan blowing effect is presented theoretically and numerically. Appropriate transformations are used to transform the governing boundary layer equations into non-linear ordinary differential equations, before being solved numerically using the Runge-Kutta-Fehlberg method. The effect of the governing parameters on the dimensionless velocities, temperature, nanoparticle volume fraction (concentration, density of motile microorganisms as well as on the local skin friction, local Nusselt, Sherwood number and motile microorganisms numbers are thoroughly examined via graphs. It is observed that the Stefan blowing increases the local skin friction and reduces the heat transfer, mass transfer and microorganism transfer rates. The numerical results are in good agreement with those obtained from previous literature. Physical quantities results from this investigation show that the effects of higher disk stretching strength and suction case provides a good medium to enhance the heat, mass and microorganisms transfer compared to blowing case.

  17. A Stefan model for mass transfer in a rotating disk reaction vessel

    KAUST Repository

    BOHUN, C. S.

    2015-05-04

    Copyright © Cambridge University Press 2015. In this paper, we focus on the process of mass transfer in the rotating disk apparatus formulated as a Stefan problem with consideration given to both the hydrodynamics of the process and the specific chemical reactions occurring in the bulk. The wide range in the reaction rates of the underlying chemistry allows for a natural decoupling of the problem into a simplified set of weakly coupled convective-reaction-diffusion equations for the slowly reacting chemical species and a set of algebraic relations for the species that react rapidly. An analysis of the chemical equilibrium conditions identifies an expansion parameter and a reduced model that remains valid for arbitrarily large times. Numerical solutions of the model are compared to an asymptotic analysis revealing three distinct time scales and chemical diffusion boundary layer that lies completely inside the hydrodynamic layer. Formulated as a Stefan problem, the model generalizes the work of Levich (Levich and Spalding (1962) Physicochemical hydrodynamics, vol. 689, Prentice-Hall Englewood Cliffs, NJ) and will help better understand the natural limitations of the rotating disk reaction vessel when consideration is made for the reacting chemical species.

    The Maxwell-Stefan model is a popular diffusion model originally developed to model diffusion of gases, which can be considered thermodynamically ideal mixtures, although its application has been extended to model diffusion in non-ideal liquid mixtures as well. A drawback of the model is that it requires the Maxwell-Stefan diffusion coefficients, which are not based on measurable quantities but they have to be estimated. As a result, numerous estimation methods, such as the Darken model, have been proposed to estimate these diffusion coefficients. However, the Darken model was derived, and is only well defined, for binary systems. This model has been extended to ternary systems according to two proposed forms, one by R. Krishna and J. M. van Baten, Ind. Eng. Chem. Res., 2005, 44, 6939-6947 and the other by X. Liu, T. J. H. Vlugt and A. Bardow, Ind. Eng. Chem. Res., 2011, 50, 10350-10358. In this paper, the two forms have been analysed against the ideal ternary system of methanol/butan-1-ol/propan-1-ol and using experimental values of self-diffusion coefficients. In particular, using pulsed gradient stimulated echo nuclear magnetic resonance (PGSTE-NMR) we have measured the self-diffusion coefficients in various methanol/butan-1-ol/propan-1-ol mixtures. The experimental values of self-diffusion coefficients were then used as the input data required for the Darken model. The predictions of the two proposed multicomponent forms of this model were then compared to experimental values of mutual diffusion coefficients for the ideal alcohol ternary system. This experimental-based approach showed that the Liu's model gives better predictions compared to that of Krishna and van Baten, although it was only accurate to within 26%. Nonetheless, the multicomponent Darken model in conjunction with self-diffusion measurements from PGSTE-NMR represents an attractive method for a rapid estimation of mutual diffusion in multicomponent systems, especially when compared to exhaustive

    Jožef Stefan Institute recently commissioned a high brightness H{sup −} ion beam injection system for its existing tandem accelerator facility. Custom developed by High Voltage Engineering Europa, the multicusp ion source has been tuned to deliver at the entrance of the Tandetron™ accelerator H{sup −} ion beams with a measured brightness of 17.1 A m{sup −2} rad{sup −2} eV{sup −1} at 170 μA, equivalent to an energy normalized beam emittance of 0.767 π mm mrad MeV{sup 1/2}. Upgrading the accelerator facility with the new injection system provides two main advantages. First, the high brightness of the new ion source enables the reduction of object slit aperture and the reduction of acceptance angle at the nuclear microprobe, resulting in a reduced beam size at selected beam intensity, which significantly improves the probe resolution for micro-PIXE applications. Secondly, the upgrade strongly enhances the accelerator up-time since H and He beams are produced by independent ion sources, introducing a constant availability of {sup 3}He beam for fusion-related research with NRA. The ion beam particle losses and ion beam emittance growth imply that the aforementioned beam brightness is reduced by transport through the ion optical system. To obtain quantitative information on the available brightness at the high-energy side of the accelerator, the proton beam brightness is determined in the nuclear microprobe beamline. Based on the experience obtained during the first months of operation for micro-PIXE applications, further necessary steps are indicated to obtain optimal coupling of the new ion source with the accelerator to increase the normalized high-energy proton beam brightness at the JSI microprobe, currently at 14 A m{sup −2} rad{sup −2} eV{sup −1}, with the output current at 18% of its available maximum.

  9. Relationship between Neumann solutions for two-phase Lamé-Clapeyron-Stefan problems with convective and temperature boundary conditions

    Full Text Available We obtain for the two-phase Lamé-Clapeyron-Stefan problem for a semi-infinite material an equivalence between the temperature and convective boundary conditions at the fixed face in the case that an inequality for the convective transfer coefficient is satisfied. Moreover, an inequality for the coefficient which characterizes the solid-liquid interface of the classical Neumann solution is also obtained. This inequality must be satisfied for data of any phase-change material, and as a consequence the result given in Tarzia, Quart. Appl. Math., 39 (1981, 491-497 is also recovered when a heat flux condition was imposed at the fixed face.

  10. Maxwell-Stefan diffusion: a framework for predicting condensed phase diffusion and phase separation in atmospheric aerosol

    The composition of atmospheric aerosol particles has been found to influence their micro-physical properties and their interaction with water vapour in the atmosphere. Core-shell models have been used to investigate the relationship between composition, viscosity and equilibration timescales. These models have traditionally relied on the Fickian laws of diffusion with no explicit account of non-ideal interactions. We introduce the Maxwell-Stefan diffusion framework as an alternative method, which explicitly accounts for non-ideal interactions through activity coefficients. e-folding time is the time it takes for the difference in surface and bulk concentration to change by an exponential factor and was used to investigate the interplay between viscosity and solubility and the effect this has on equilibration timescales within individual aerosol particles. The e-folding time was estimated after instantaneous increases in relative humidity to binary systems of water and an organic component. At low water mole fractions, viscous effects were found to dominate mixing. However, at high water mole fractions, equilibration times were more sensitive to a range in solubility, shown through the greater variation in e-folding times. This is the first time the Maxwell-Stefan framework has been applied to an atmospheric aerosol core-shell model and shows that there is a complex interplay between the viscous and solubility effects on aerosol composition that requires further investigation.

    2009-11-01

    A finite difference lattice Boltzmann scheme for homogeneous mixture modeling, which recovers Maxwell-Stefan diffusion model in the continuum limit, without the restriction of the mixture-averaged diffusion approximation, was recently proposed [P. Asinari, Phys. Rev. E 77, 056706 (2008)]. The theoretical basis is the Bhatnagar-Gross-Krook-type kinetic model for gas mixtures [P. Andries, K. Aoki, and B. Perthame, J. Stat. Phys. 106, 993 (2002)]. In the present paper, the recovered macroscopic equations in the continuum limit are systematically investigated by varying the ratio between the characteristic diffusion speed and the characteristic barycentric speed. It comes out that the diffusion speed must be at least one order of magnitude (in terms of Knudsen number) smaller than the barycentric speed, in order to recover the Navier-Stokes equations for mixtures in the incompressible limit. Some further numerical tests are also reported. In particular, (1) the solvent and dilute test cases are considered, because they are limiting cases in which the Maxwell-Stefan model reduces automatically to Fickian cases. Moreover, (2) some tests based on the Stefan diffusion tube are reported for proving the complete capabilities of the proposed scheme in solving Maxwell-Stefan diffusion problems. The proposed scheme agrees well with the expected theoretical results.

    2018-01-01

    The defining relations for the thermodynamic diffusion and heat fluxes in a multicomponent, partially ionized gas mixture in an external electromagnetic field have been obtained by the methods of the kinetic theory. Generalized Stefan-Maxwell relations and algebraic equations for anisotropic transport coefficients (the multicomponent diffusion, thermal diffusion, electric and thermoelectric conductivity coefficients as well as the thermal diffusion ratios) associated with diffusion-thermal processes have been derived. The defining second-order equations are derived by the Chapman-Enskog procedure using Sonine polynomial expansions. The modified Stefan-Maxwell relations are used for the description of ambipolar diffusion in the Earth's ionospheric plasma (in the F region) composed of electrons, ions of many species, and neutral particles in a strong electromagnetic field.

    Recently, in Tarzia (Thermal Sci 21A:1-11, 2017) for the classical two-phase Lamé-Clapeyron-Stefan problem an equivalence between the temperature and convective boundary conditions at the fixed face under a certain restriction was obtained. Motivated by this article we study the two-phase Stefan problem for a semi-infinite material with a latent heat defined as a power function of the position and a convective boundary condition at the fixed face. An exact solution is constructed using Kummer functions in case that an inequality for the convective transfer coefficient is satisfied generalizing recent works for the corresponding one-phase free boundary problem. We also consider the limit to our problem when that coefficient goes to infinity obtaining a new free boundary problem, which has been recently studied in Zhou et al. (J Eng Math 2017. https://doi.org/10.1007/s10665-017-9921-y).

    Fowler, K.; Connolly, P.; Topping, D. O.

    2016-12-01

    Until now, non-reactive mixing through secondary organic aerosols has been modelled using the Fickian laws of diffusion (Shiraiwa, 2013). Atmospheric aerosols are comprised of components with varying physical and chemical properties, including solubility. This is confirmed by virtue of the fact that liquid-liquid phase separations can exist within individual aerosol particles (Bertram, 2011). This spectrum of solubility means that modelling diffusion according to the Fickian definition is subject to unknown errors.In this study, we introduce a new framework of diffusion through aerosol particles based on Maxwell-Stefan's law. This framework uses a gradient in chemical potential to drive mixing through individual particles, for which we use the UNIFAC model. Including non-ideal effects of diffusion allows mixing to occur against the concentration gradient and liquid-liquid phase separations to be treated alongside any changes in viscosity of the mixture. Results from this framework give new insights on the interplay between thermodynamic factors and phase state changes on aerosol-cloud interactions. We further confirm that understanding the composition of aerosol particles is essential to better model their interactions in cloud systems.

    Full Text Available In the Vita of despot Stefan Lazarević, Belgrade is compared to Jerusalem The use of this topos is aimed at a social construction of meaning within the framework of historically determined cultural discourse, based on the premise that culture itself can be observed as a complex system of signs constantly open to redefinition. This implies that the approach to its more profound understanding must rely on a method based on reconceptualization of the problem of text and context. Therefore, the true object of investigation becomes the relation between text and society whose activities are themselves perceived as a sort of behavioral text, in which that relation functions as two homologous systems of signs. As a result, our attention is focused on activities which produce social and cultural phenomena and objects — actually on the means by the use of which a world filled with meaning is created. Apart from texts, those means, as real as the text itself, belong to the instruments of creating sacred space or hierotopy, a phenomenon historically recognized as translatio Hierosolymi. Beyond any doubt, in the eyes of homo medievalis, the absolute paradigm of hierotopic activity is Constantinople the capital of the Empire and universal model through the emulation of which or through the appropriation of whose elements of identity (ranging from cults of saints to visual identity throughout history, and in particular in the later middle ages (especially following the events of 1204, a growing number of other points in the Christian oikoumene gains the status of center as a God-chosen and God-protected place — Arta, Trebizond and Nicea, Paris and Venice, Novgorod and Moscow, to name just the most prominent examples In investigating the case of Belgrade, attention is focused on the modes and vehicles of hierotopy which in the days of despot Stefan Lazarević (1402-1427 were laid as the foundation of likening Belgrade and Jerusalem as the utmost example of

Seu desejo de querer ver no Brasil da década de 1940 uma terra livre das intolerâncias e violências que assolavam a Europa de então, fustigada pela 2ª Guerra Mundial, fez com que Zweig revivesse a imagem mitológica de que o Brasil era uma terra paradisíaca, um éden reencontrado.

Curiosamente o escritor/profeta, muitas vezes, trai suas profecias, projetando no Brasil valores de sua Europa e às vezes chega mesmo a se contradizer no que tange à questão da tolerância e harmonia que via no Brasil.Palavras-chave: Stefan Zweig; Literatura de viagem; Profetismo; Intolerância; Messianismo.ABSTRACTThis article makes a reading of Viennese writer Stefan Zweig’s book Brasil, um país do futuro (Brazil, a country of the future, pointing out how far the author’s discourse is endowed with certain prophetical aspects when it refers to Brazil. His desire to see Brazil, in the 40’s, as a land free from the intolerance and violence that devastated Europe during World War II made Zweig revive the mythological image of the country as a paradisiacal land, a rediscovered Eden. His description of Brazil, rather than optimistic, acquires a prophetical aspect when he emphasizes the fact that the prevailing harmony and peace of the country made it a locus for the advent of a messianic and utopian future. Curiously, the writer/prophet often betrayed his prophecies, projecting in Brazil old European values, and sometimes contradicting himself as to the issue of tolerance and harmony that he witnessed in

  3. The idea of the perfect city in the state of prince Lazar and despotes Stefan Lazarević

    foundations. The new wave of piety originated from the circles of educated refugee monks, who found refuge in the small palaces, where a rather complex, monastic-feudal mentality gradually formed. The palace culture of those centers had their own pious literature, where various visions of the invisible Paradise were particularly widely read. The old idea that all the righteous would attain Heaven gained a new importance and a new interpretation at the end of the XIV century. This faith in the habitation of Heaven began to be linked to buildings on earth - to cities and monasteries. The depiction of Heaven, or the Upper Jerusalem, as it was called, had already begun in Serbian painting in the mid-fourteenth century. Around 1400, however, there was an insistence on presenting how the organization of the palace was similar to the heavenly hierarchy, how the courtiers with their appearance looked like the inhabitants of Paradise, and how the building the royal court erected resembled the heavenly houses of the 'New Jerusalem'. Such descriptions about the resemblance to the dwellings of Heaven were very frequent in Serbian literature of the late fourteenth and early fifteenth centuries. Prince Lazar resorted with increasing frequency to creating buildings according to the image of the 'Upper Jerusalem', especially the monastery of Ravanica. Andonije Epaktit gave the most exhaustive account of Ravanica-Jerusalem: Ravanica was the 'dwelling of God' and the 'door to Heaven', it had seven pinnacles or pyrgoi, and accordingly, it was similar to Jerusalem, Rome and Constantinople, and it was inhabited by monk-angels. Constantme the Philosopher wrote in a similar vein. His magnificent description of Belgrade as Jerusalem in the Life of Despotes Stefan Lazarević falls among the most important eulogies of the cities in Byzantine culture. And Belgrade - like Jerusalem, Rome and Constantinople - has 'seven pinnacles'. It resembles both the 'lower' and the 'higher' Jerusalem; so as to

  4. ”När det tar slut och börjar om igen”: Ekokritiska perspektiv på Stefan Castas ungdomsdystopier

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available The Swedish author Stefan Casta has written several books for children and adults, thematically addressing nature and environment. This paper highlights and discusses ideological and aesthetical aspects in his recent novel, Den gröna cirkeln (2011 and its sequel, Under tiden (2012, from an ecocritical perspective. The novels combine environmental commitment with a dystopian story about four young people who survive a climate catastrophe but get lost in a world they no longer recognize and where ordinary logic does not seem to exist. The paper elucidates this process by a comparison with Buell’s (2001 concept of toxic discourse as there are several parallells, such as elements like a lost paradise, inescapable toxic, and the oppression of powerful societal interests, throughout the story. Simultaneously, ambivalence towards culture and civilization is expressed. Nature and culture become intertwined in a way that differs from the conventional dichotomy and this complexity is the supporting structure of the texts. The four teenagers, and even more so the following generation, become symbols of a new future, a pattern recognized from much dystopian as well as children’s fiction, where the weak and oppressed turn out to be the heroes. The optimistic and didactic ambition in this kind of dystopian stories is often aimed at creating an engagement for environmental issues and a sustainable future among young people. By placing the story in an imagined future as well as adding fantastic elements, Stefan Casta creates a kind of ”Verfremdungseffekt” on phenomena we often do not question in our lifestyle. This could be a liberating relativization to the young readers; the social and cultural drives that rule many of our life choices are not essential and can therefore always be reconsidered.

  5. Rigorous dynamic model of a direct methanol fuel cell based on Maxwell-Stefan mass transport equations and a Flory-Huggins activity model: Formulation and experimental validation

    Science.gov (United States)

    Schultz, Thorsten; Sundmacher, Kai

    A one-dimensional rigorous process model of a single-cell direct methanol fuel cell (DMFC) is presented. Multi-component mass transport in the diffusion layers and the polymer electrolyte membrane (PEM) is described using the generalised Maxwell-Stefan (MS) equation for porous structures. In the PEM, also local swelling behaviour and non-idealities are accounted for by a Flory-Huggins model for the activities of the mobile species inside the pores of the PEM. Phase equilibria between the pore liquid inside the PEM and those inside the pores of both catalyst layer are formulated based on literature data and activity models. Although two-phase behaviour in both diffusion layers is neglected, the model shows good agreement to own experimental data over a wide range of operating conditions, with respect to methanol and water crossover fluxes as well as to current-voltage characteristics. Only for very low current densities and in the limiting current regime significant deviations between model and experiments are found.

  6. Law of cooling, heat conduction and Stefan-Boltzmann radiation laws fitted to experimental data for bones irradiated by CO2 laser.

    Lévesque, Luc

    2014-03-01

    The rate of cooling of domesticated pig bones is investigated within the temperature range of 20°C-320°C. Within the afore-mentioned temperature range, it was found that different behaviors in the rate of cooling were taking place. For bones reaching a temperature within the lower temperature range of 20°C-50°C, it was found that the rate of cooling is mostly governed by the empirical Newton's law of cooling. It is also shown that a transition is taking place somewhere within 50°C-100°C, where both the heat conduction equation and Newton's law apply. As bones can be raised at a fairly high temperature before burning, it was found that the rate of cooling within the range 125°C-320°C is mostly behaving according to the heat conduction equation and Stefan-Boltzmann radiation law. A pulsed CO2 laser was used to heat the bones up to a given temperature and the change of temperature as a function of time was recorded by non-contact infrared thermometer during the cooling period.

    Directory of Open Access Journals (Sweden)

    2011-04-01

    Full Text Available Recently, we predicted the existence of fundamental particles in Nature, neutral Light Particles with spin 1 and rest mass m = 1 : 8 10E-4 me, in addition to electrons, neutrons and protons. We call these particles Light Bosons because they create electromagnetic field which represents Planck’s gas of massless photons together with a gas of Light Par- ticles in the condensate. Such reasoning leads to a breakdown of Stefan–Boltzmann’s law at low temperature. On the other hand, the existence of new fundamental neutral Light Particles leads to correction of such physical concepts as Bose-Einstein conden- sation of photons, polaritons and exciton polaritons.

    Full Text Available Illness requires narration: it fulfills a crucial role in the cooperation between patient and doctor, is demanded by one’s social environment, and emerges in the identity work triggered by a medical diagnosis (which in itself constitutes a first narrative model for the ill person to accept, rework or reject. This article examines how contemporary illness narratives recount such communication and how they reflect on the possibilities and limits of narration. It triangulates three life writing texts: Verena Stefan’s Fremdschläfer (2007 about the Swiss-German author’s own experience of breast cancer, Siri Hustvedt’s The Shaking Woman or a History of my Nerves (2010, describing the novelist’s quest for knowledge about the ambiguous shaking she displays, and Paul Kalanithi’s When Breath Becomes Air (2016, which focuses on the author’s role reversal (from doctor to patient and the approach of his death from lung cancer. Narrative patterns and role models are being traced here; questions about voice and agency appear central in each text. What knowledge does such contemporary life writing hold, and what does it have to say about the dominant conceptualisations of states of health and illness?

  18. Operation and maintenance of the 250 kW TRIGA Mark II reactor at the J. Stefan Institute

    International Nuclear Information System (INIS)

    Dimic, V.

    1980-01-01

    Since the last TRIGA Conference, the reactor has completed approximately 4800 operating hours without major problems. The problem with the lack of fresh fuel elements is going to be solved after the signing of a new agreement for the supply of fuel between the IAEA, the Yugoslav and US Governments. In order to increase the reactivity the fuel elements from the outer zone we shuffled to the inner zone, and old fuel elements from the fuel container were added to the F ring. Due to the large demand for irradiation, a new pneumatic facility for loading and unloading the samples in the rotary specimen rack or central thimble has been constructed and installed. A configuration based on two microcomputers in a master slave hierarchical organisation for automatic data logging and direct has been finished and the system was installed after extensive testing. The reactor operation is now more reliable and simpler for the operators. Some of the original instrumentation of the reactor has been gradually substituted because of ageing: a start-up channel with digital display, a power integrator, a digital electronic rod position indicator, a digital power range switch without resistors and a new 2-pen recorder have been installed. The following instrumentation was ordered by the IAEA from the Hartmann and Brawn company: a start-up channel, a log channel, a safety channel, an automatic power control and water temperature, conductivity, level and activity measuring units. During the last year, with the help of our nuclear chemistry department, the production of high concentration and high purity technetium-99 m for medical use was developed by a solvent extraction method

  1. A Sinner or a Saint: the image of Mary, Queen of Scots in the works of Friedrich Schiller, Juliusz Słowacki and Stefan Zweig

    Melkov Andrey Sergeevich

    2017-04-01

    Full Text Available The artistic image of Mary, Queen of Scots in the works of F. Schiller, J. Słowacki and S. Zweig are researched in the article. The Queen’s life, character, inner world and psychological portrait appear on the pages of the classicists’ works in the context of the era she lived. The turbulent historical processes that took place in England and Scotland at the end of the Middle Ages and the beginning of the Early Modern Period led to the phenomenon of Mary Stuart’s personality. Obviously the creativity of the authors whose works were dedicated to Mary I of Scotland was influenced by the experience learned from the lessons of their time. It was reflected in the classicists’ analyses and description of the past. Romanticistsof the 19th century, F. Schiller and J. Słowacki, interpreted the personality of Mary Stuart in the sinner/saint dichotomy, but S. Zweig at the historic break in the 30s of the 20th century departed from the unilateralism of such an approach. In his romanced biography of Mary, Queen of Scots he tells about the rises and falls of his heroine. S. Zweig presents Mary I of Scotland as a wonderful, passionate and suffering woman, who even 400 years after her death inspires and excites peoples’ minds and hearts.

    2012-06-01

    Full Text Available The article examines the shift in the field, since the 1970s, from a predominant focus on the early period of Islamic art and architecture in the ‘central zone’ of the Fertile Crescent to a broader chronological and geographical scope. This shift has contributed, among other things, to a change of emphasis from artistic unity to variety, accompanied by an increasing diversification of concepts and approaches including dynastic, regional, media-based, textual, theoretical, critical, and historiographical inquiries. The article seeks to address the unresolved methodological tensions arising from the expanded scope of the field, along with concomitant anxieties over the fragmentation of its traditional ‘universalism’. It begins by outlining the premises of still prevalent approaches inherited from the construction of the field during the late nineteenth and early twentieth centuries, a field rooted in the entangled legacies of Orientalism, nationalism, and dilletantism. The article then reviews the statements of some scholars on the state and future of the field before turning to personal reflections on challenges posed by its expanding horizons and its relationship to the Museum.

    The Swarm constellation of three satellites measures the magnetic signal of the Earth using both a Vector Field Magnetometer and an Absolute Scalar Magnetometer. A Micro Advanced Stellar Compass (μASC) mounted on a common, supposedly stable, optical bench precisely determines its inertial attitude. However, comparison of the Inter Boresight Angle shows a relative attitude variation between the μASC Camera Head Units. These misalignments between Camera Head Units and a geomagnetic reference frame cannot be explained by incorrect aberration correction (as theorized by Maus). Herceg et al. found them to be caused by thermal gradient sensitivity of the optical bench system, opposing the underlying assumption of perfect platform stability. The results after applying thermal corrections show significant decrease in root mean square, with Inter Boresight Angle of thermally corrected data being nearly flat and clean from any variation caused by thermoelastic effects.

    Full Text Available Das Zustandekommen der hier vorgelegten Beiträge zum Thema »Rechtsgewohnheiten« bedarf einer kurzen Erläuterung. Von dem Buch(1 Martin Pilchs, dessen – nun hier ausgearbeitet vorliegender – Vortrag(2 die ebenfalls in überarbeiteter Form wiedergegebene Diskussion einleitete, ging ein unerwarteter und ungewöhnlicher Anstoß für die Zunft der Rechtshistoriker und Historiker aus. Ein österreichischer Ministerialbeamter mit rechtstheoretischer Schulung, der aber auch Physiker und Mathematiker ist, wendet sich einer normtheoretischen Studie zu. In ihr spielt die mittelalterliche ungelehrte, weitgehend orale Rechtstradition als Forschungsfeld eine wichtige Rolle als Gegenbild zu einem einseitigen modernen Normverständnis. Innerhalb dieser Diskussion setzt sich Pilch intensiv, und von der Seite der Theorie kommend kritisch, mit einer rechtshistorischen Diskussion der letzten Jahrzehnte um den Begriff der Rechtsgewohnheit auseinander; er bezieht aber auch neue Erklärungsmodelle der Mittelalterhistoriker zu den Formen ritueller Konfliktbeilegung in der politischen Führungsschicht von Adel und Königtum (Gerd Althoff, sowie Erklärungsversuche vom Konzept der Ordnungskonfigurationen her (Stefan Weinfurter, Bernd Schneidmüller in seine Überlegungen mit ein. Dem provozierenden Stichwort »Rechtsgewohnheiten« im Titel des Buches von Martin Pilch ist es wohl zu verdanken, dass alle drei angesprochenen Forschungsrichtungen sehr bald den Kontakt mit dem Autor aufnahmen.

    Conditioning of mostly liquid uranium containing technological radioactive waste emerging from the past research activities at the Jozef Stefan Institute is described. The waste was first thoroughly characterised, then the radionuclides present solidified by appropriate chemical treatment, and the final product separated and prepared for storage in compliance with the legislation. The activities were carried out within the recently renewed Hot Cells Facility of the Jozef Stefan Institute and the overall process resulted in substantial volume reduction of the waste initially present.

    Symbolic dynamics provides a general framework to describe complexity of dynamical behaviour. After a discussion of the state of the filed special emphasis will be made on the role of transfer matrix (the Stefan matrix) both in deriving the grammar from known symbolic dynamics and in extracting the rules from experimental data. The block structure of the Stefan matrix may serve as another indicator of complexity of the associated dynamics. (author). 33 refs, 6 figs

    2003-06-01

    The ice formation in a water body is examined for the computation of temperature field, phase change and a moving ice-water interface whose location is not known á priori. This is classically referred to as the Stefan problem [Rubinstein, L.I. (1971) The Stefan Problem (American Mathematical Society, Providence, Rhode Island 02904]. Based on the Duvaut [Duvaut, G. (1973) "Résolution d'un probléme Stefan" C.R. Acad Sci. Paris 276, 1461-1463] transformation, the governing equations for heat conduction are formulated within a variational principle that is readily amenable to a standard finite element solution without remeshing. Numerical simulation results pertaining to the freezing of tumour tissue in a multi-cryoprobe cryosurgery are presented. These results lend both quantitative and graphical support to the current empirical standards of "effective therapy" in view of refining clinical applications.

  3. Lattice Boltzmann model for melting with natural convection

    International Nuclear Information System (INIS)

    Huber, Christian; Parmigiani, Andrea; Chopard, Bastien; Manga, Michael; Bachmann, Olivier

    2008-01-01

    We develop a lattice Boltzmann method to couple thermal convection and pure-substance melting. The transition from conduction-dominated heat transfer to fully-developed convection is analyzed and scaling laws and previous numerical results are reproduced by our numerical method. We also investigate the limit in which thermal inertia (high Stefan number) cannot be neglected. We use our results to extend the scaling relations obtained at low Stefan number and establish the correlation between the melting front propagation and the Stefan number for fully-developed convection. We conclude by showing that the model presented here is particularly well-suited to study convection melting in geometrically complex media with many applications in geosciences

    Full Text Available This research examines a badly washed-out portrait composition of Prince Lazar, Princess Milica and their sons, Stefan and Vuk, in the Ravanica church. The opinion is that it was not painted later, over the original layer of the frescoes, but that it was made simultaneously with the other wall paintings of the lowest zones of the church. Considering the age of Stefan represented in the portrait composition, it is assumed that the decoration of the church was completed around 1385.

    Public information is one of the important permanent activities of the Nuclear Training Centre Milan Copic at Jozef Stefan Institute in Ljubljana. It is focused on youngsters and about one half of every generation of schoolchildren in Slovenia is informed on nuclear energy. Every year since 1993 we poll youngsters using the same basic set of questions. For comparison we also polled professionals (our colleagues at the Jozef Stefan Institute) using the same questionnaire. Opinion of youngsters about nuclear energy in Slovenia can be considered favourable now (71 %), but the trend is negative. The support is dropping from initial 83% for two consecutive years. Opposition to NPP Krsko operation remains low. (author)

    The achievements of the Jesuits from the Austrian and Bohemian provinces, who have published books on chemistry are focused. Their links with the area of today's Slovenia are particularly exposed. The guidelines which have enabled prompt victories of the ideas about the structure of matter of Jesuit Ru|er Bokovi are indicated. Inconceivable fast spread of Bošković's adherents in the Hapsburg monarchy is compared with a similar rapid introduction of the kinetic theories of atoms of Slovene Jožef Stefan and Ludwig Boltzmann in the same geographical area. Boltzmann was not only Stefan's best student, but he also married a half Slovenian maid.

  2. Homeomorphisms of R and the Davey Space

    Directory of Open Access Journals (Sweden)

    Sheila Carter

    2004-04-01

    Full Text Available Up to homeomorphism, there are 9 topologies on a three point set {a, b, c}. Among the resulting topological spaces we have the so called Davey space, where the only non-trivial open set is, let us say, {a}. This is an interesting topological space to the extent that every topological space can be embedded in a product of Davey spaces. In this note we will consider the problem of obtaining the Davey space as a quotient R/G, where G is a suitable homeomorphism group. The present work can be regarded as a follow-up to some previous work done by one of the authors and Bernd Wegner.

    2000-05-25

    This paper has dealt with the heat storage characteristics of fine microcapsules packed with latent heat storage material in the water layer. The heat storage operation to the latent microcapsules was carried out using hot air bubbles by direct contact heat exchange. The microcapsule consists of n-paraffin as a core latent-heat storage material and melamine resin as a coating substance. The relation of the completion time of latent-heat storage to some parameters was examined experimentally. The non-dimensional correlation equations for the completion time of latent-heat storage process had were derived in terms of the ratio of water layer height to diameter of microcapsule, Reynolds number for air flow, Stefan number and modified Stefan number for absolute humidity of flowing air.

    , overcrowded cities and a world power in rapid economic growth – these are some of the images that are often called to mind when the talk turns to China. In the solo exhibition Out of, In, On, and Off, Stefan A. Pedersen focuses on China as a projection surface for the West’s ideas, fascination and criticism....... The exhibition is based on Stefan A. Pedersen’s journey through eastern China earlier this year, which was organised on the basis of diary entries and an unfinished film from a trip the artist’s late father undertook forty years ago. On the first floor at Overgaden, a line of semi-transparent curtains runs....... The contemplative, almost meditative film sequences contrast with the usual pictorial representations of China, and balance instead on the borderline between information and non-information. On the other side of the curtains a soundtrack can be heard, in which a voice talks about travel, ideas, films, deprivation...

    Providing public information is one of the main activities of The Nuclear Training Centre (ICJT) at the Jozef Stefan Institute. Our primary target is students of primary and secondary schools. The lecture they listen to during their visit to our centre was old fashioned since we used classic overhead projector. We have modernized it with an LCD projector and computer-based interactive presentation in order to improve students' comprehension. (author)

    We have run computer simulations of the quark and gluon internal energies in SU(3) lattice gauge theory neglecting dynamical fermion loops. At the first-order deconfinement - chiral-symmetry restoration transition, the internal energies display large discontinuities which nearly saturate the Stefan-Boltzmann free quark and gluon limits. The total latent heat per unit volume is roughly 1.50 +- 0.50 GeV/fm 3 . We present critical remarks and timing estimates for fermion computer simulation methods

  15. Solving one-dimensional phase change problems with moving grid method and mesh free radial basis functions

    International Nuclear Information System (INIS)

    Vrankar, L.; Turk, G.; Runovc, F.; Kansa, E.J.

    2006-01-01

    Many heat-transfer problems involve a change of phase of material due to solidification or melting. Applications include: the safety studies of nuclear reactors (molten core concrete interaction), the drilling of high ice-content soil, the storage of thermal energy, etc. These problems are often called Stefan's or moving boundary value problems. Mathematically, the interface motion is expressed implicitly in an equation for the conservation of thermal energy at the interface (Stefan's conditions). This introduces a non-linear character to the system which treats each problem somewhat uniquely. The exact solution of phase change problems is limited exclusively to the cases in which e.g. the heat transfer regions are infinite or semi-infinite one dimensional-space. Therefore, solution is obtained either by approximate analytical solution or by numerical methods. Finite-difference methods and finite-element techniques have been used extensively for numerical solution of moving boundary problems. Recently, the numerical methods have focused on the idea of using a mesh-free methodology for the numerical solution of partial differential equations based on radial basis functions. In our case we will study solid-solid transformation. The numerical solutions will be compared with analytical solutions. Actually, in our work we will examine usefulness of radial basis functions (especially multiquadric-MQ) for one-dimensional Stefan's problems. The position of the moving boundary will be simulated by moving grid method. The resultant system of RBF-PDE will be solved by affine space decomposition. (author)

    2015-01-01

    If you find yourself repeatedly witnessing a situation of inter personal conflict or tension between other colleagues, you have a choice: you can either turn a blind eye to it or you can try to help. In the latter case, you may wish to get another perspective or some guidance before taking steps.   Stefan, Paul and Lucas work together on a challenging project. Over time, Lucas has started to notice Paul’s verbally aggressive behaviour towards Stefan: he frequently criticises him in public, cuts him short at meetings when he is trying to make his point and is known to make derogatory remarks about him behind his back. Stefan does not seem to react but the tension between them is evident and Lucas feels increasingly uncomfortable in their company. It is never easy to know whether or not to intervene in these delicate situations, and the ‘bystander effect’ - where people do nothing - tends to prevail in most workplace cultures. Bystanders hesitate to act because th...

    I propose a novel mechanism for the brain cancer tissue treatment: nonlinear interaction of ultrashort pulses of beat-photon, (ω1 -- ω2) , or double-photon, (ω1 +ω2) , beams with the cancer tissue. The multiphoton scattering is described via photon diffusion equation. The open-scull cerebral tissue can be irradiated with the beat-modulated photon pulses with the laser irradiances in the range of a few mW/cm2 , and repetition rate of a few 100s Hz generated in the beat-wave driven free electron laser.

  18. Thermal phenomenae in nuclear fuel rods

    International Nuclear Information System (INIS)

    Baigorria, Carlos.

    1983-12-01

    Thermal phenomenae occurring in a nuclear fuel rod under irradiation are studied. The most important parameters of either steady or transient thermal states are determined. The validity of applying the Fourier's approximation equations to these problems is also studied. A computer program TRANS is developed in order to study the transient cases. This program solves a system of coupled, non-linear partial differential equations, of parabolic type, in cylindrical coordinates with various boundary conditions. The benchmarking of the TRANS program is done by comparing its predictions with the analytical solution of some simplified transient cases. Complex transient cases such as those corresponding to characteristic reactor accidents are studied, in particular for typical pressurized heavy water reactor (PHWR) fuel rods, such as those of Atucha I. The Stefan problem emerging in the case of melting of the fuel element is solved. Qualitative differences between the classical Stefan problem, without inner sources, and that one, which includes sources are discussed. The MSA program, for solving the Stefan problem with inner sources is presented; and furthermore, it serves to predict thermal evolution, when the fuel element melts. Finally a model for fuel phase change under irradiation is developed. The model is based on the dimensional invariants of the percolation theory when applied to the connectivity of liquid spires nucleated around each fission fragment track. Suggestions for future research into the subject are also presented. (autor) [es

  19. 29th Workshop on Recent Developments in Computer Simulation Studies in Condensed Matter Physics

    International Nuclear Information System (INIS)

    2016-01-01

    Thirty years ago, because of the dramatic increase in the power and utility of computer simulations, The University of Georgia formed the first institutional unit devoted to the application of simulations in research and teaching: The Center for Simulational Physics. Then, as the international simulations community expanded further, we sensed the need for a meeting place for both experienced simulators and newcomers to discuss inventive algorithms and recent results in an environment that promoted lively discussion. As a consequence, the Center for Simulational Physics established an annual workshop series on Recent Developments in Computer Simulation Studies in Condensed Matter Physics. This year's highly interactive workshop was the 29th in the series marking our efforts to promote high quality research in simulational physics. The continued interest shown by the scientific community amply demonstrates the useful purpose that these meetings have served. The latest workshop was held at The University of Georgia from February 22-26, 2016. It served to mark the 30 th Anniversary of the founding of the Center for Simulational Physics. In addition, during this Workshop we celebrated the 60 th birthday of our esteemed colleague Prof. H.-Bernd Schuttler. Bernd has not only contributed to the understanding of strongly correlated electron system, but has made seminal contributions to systems biology through the introduction of modern methods of computational physics. These Proceedings provide a “status report” on a number of important topics. This on-line “volume” is published with the goal of timely dissemination of the material to a wider audience. This program was supported in part by the President's Venture Fund through the generous gifts of the University of Georgia Partners and other donors. We also wish to offer thanks to the Office of the Vice-President for Research, the Franklin College of Arts and Sciences, and the IBM Corporation for partial

  20. Modelling of active layer thickness evolution on James Ross Island in 2006-2015

    Science.gov (United States)

    Hrbáček, Filip; Uxa, Tomáš

    2017-04-01

    Antarctic Peninsula region has been considered as one of the most rapidly warming areas on the Earth. However, the recent studies (Turner et al., 2016; Oliva et al., 2017) showed that significant air temperature cooling began around 2000 and has continued until present days. The climate cooling led to reduction of active layer thickness in several parts of Antarctic Peninsula region during decade 2006-2015, but the information about spatiotemporal variability of active layer thickness across the region remains largely incoherent due to lack of active layer temperature data from deeper profiles. Valuable insights into active layer thickness evolution in Antarctic Peninsula region can be, however, provided by thermal modelling techniques. These have been widely used to study the active layer dynamics in different regions of Arctic since 1990s. By contrast, they have been employed much less in Antarctica. In this study, we present our first results from two equilibrium models, the Stefan and Kudryavtsev equations, that were applied to calculate the annual active layer thickness based on ground temperature data from depth of 5 cm on one site on James Ross Island, Eastern Antarctic Peninsula, in period 2006/07 to 2014/15. Study site (Abernethy Flats) is located in the central part of the major ice-free area of James Ross Island called Ulu Peninsula. Monitoring of air temperature 2 m above ground surface and ground temperature in 50 cm profile began on January 2006. The profile was extended under the permafrost table down to 75 cm in February 2012, which allowed precise determination of active layer thickness, defined as a depth of 0°C isotherm, in period 2012 to 2015. The active layer thickness in the entire observation period was reconstructed using the Stefan and Kudryavtsev models, which were driven by ground temperature data from depth of 5 cm and physical parameters of the ground obtained by laboratory analyses (moisture content and bulk density) and calculations

    Program packages SHUFFLE and FAR were developed at 'Jozef Stefan' Institute to monitor all changes of fuel assemblies during a nuclear power plant operation. Both packages were written in the Clipper language which is suitable for data base applications and allows straightforward communications with other available data bases. Packages currently run on PC machines under DOS operating system. Both packages are in routine use at a nuclear power plant Krsko, but they can be applied to any PWR power plant without significant modification. Experiences obtained from the utility in past few years triggered several improvements and new features. (author)

    2014-01-01

    In this richly illustrated book, Nobel Laureate Gerard 't Hooft and Theoretical Physicist Stefan Vandoren describe the enormous diversity of natural phenomena that take place at different time scales. In the tradition of the bestseller Powers of Ten , the authors zoom in and out in time, each step with a factor of ten. Starting from one second, time scales are enlarged until processes are reached that take much longer than the age of the universe. After the largest possible eternities, the reader is treated to the shortest and fastest phenomena known. Then the authors increase with powers of t

    Kandilarov, J.

    2013-12-01

    A new numerical method for solving the perpetual case of Ameripean options is proposed. The Ameripean delayed exercise model analyzes a new class of option model with American and ParAsian features. The model is mathematically described by ultraparabolic and parabolic PDE's which are valid over different regions. The perpetual case leads to the parabolic-elliptic two-phase Stefan problem with free internal boundary. To deal with the obtained nonlinear problem an iterative numerical method is proposed. Numerical analysis are presented and discussed.

    In this study vector and tensorial transport phenomena of heavy particles in partially ionized molecular plasmas embedded in magnetic fields are analyzed. The system of transport equations, obtained in the 17 moments approximation of the Grad's method employing the general system of transport equations for reactive partially ionized plasmas in magnetic field obtained recently in (Zhdanov, Stepanenko, 2016), is presented. Using this system, the expressions for mass, heat and momentum transport fluxes of the heavy particles in plasma are derived. For the case of diffusion of ions, atoms and molecules the system of equations of multicomponent diffusion in the Stefan-Maxwell form is obtained.

    Irradiation of materials with energetic particles produces changes in the microstructure that affect mechanical properties. In previous work the authors studied the thermal aspects of the quenching of collision cascades that involve nanoscale phase transitions between the solid and the liquid states of the target. In this work they present a rigorous treatment of these phenomena, including a detailed description of the Stefan problem in three dimensions and diffusion in thermal gradients. This approach is oriented to give a quantitative description of the influence of the primary knock-on spectrum on the microstructure short after the quenching of the heat spike

    1) Phase Transitions, represented by generalizations of the classical Stefan problem. This is studied by Kenmochi and Rodrigues by means of variational techniques. 2) Hysteresis Phenomena. Some alloys exhibit shape memory effects, corresponding to a stress-strain relation which strongly depends on temperature; mathematical physical aspects are treated in Müller's paper. In a general framework, hysteresis can be described by means of hysteresis operators in Banach spaces of time dependent functions; their properties are studied by Brokate. 3) Numerical analysis. Several models of the phenomena above can be formulated in terms of nonlinear parabolic equations. Here Verdi deals with the most updated approximation techniques.

  15. Physics of the Brain: Interaction of the Optical-Fiber-Guided Multi-Ultraviolet-Photon Beams with the Epilepsy Topion, (the Seizure Onset Area)

    Stefan, V. Alexander

    A novel method for the possible prevention of epileptic seizures is proposed, based on the multi-ultraviolet-photon beam interaction with the epilepsy topion, (nonlinear coupling of an ultra high frequency mode to the brain beta phonons). It is hypothesized that epilepsy is a chaotic-dynamics phenomenon: small electrical changes in the epilepsy-topion lead, (within the 10s of milliseconds), to the onset of chaos, (seizure--excessive electrical discharge), and subsequent cascading into adjacent areas. The ultraviolet photons may control the imbalance of sodium and potassium ions and, consequently, may prove to be efficient in the prevention of epileptic seizures.

    The fast ignition fusion pellet gain can be enhanced by a laser generated B-field shell. The B-field shell, (similar to Earth's B-field, but with the alternating B-poles), follows the pellet compression in a frozen-in B-field regime. A properly designed laser-pellet coupling can lead to the generation of a B-field shell, (up to 100 MG), which inhibits electron thermal transport and confines the alpha-particles. In principle, a pellet gain of few-100s can be achieved in this manner. Supported in part by Nikola Tesla Labs, Stefan University, 1010 Pearl, La Jolla, CA 92038-1007.

    A novel method for the treatment of the neurological diseases is proposed. The multiple-energy laser photons (the blue scanning photons and ultraviolet focusing photons) interact with the specific DNA molecules within the topion (such as Parkinson's and Alzheimer's brain topion) via the matching of laser frequency with the oscillation eigen-frequency of a particular molecule within the DNA. In this way, the corrupt molecules (the structure of molecules) can be manipulated so as to treat (eliminate) the neurological disease. Supported by Nikola Tesla Labs, Stefan University.

    2011-04-01

    The proton beam generation and focusing in fast ignition inertial confinement fusion is studied. The spatial and energy spread of the proton beam generated in a laser-solid interaction is increased due to the synergy of Weibel and Rayleigh-Taylor instabilities. The focal spot radius can reach 100 μm, which is nearly an order of magnitude larger than the optimal value. The energy spread decreases the beam deposition energy in the focal spot. Under these conditions, ignition of a precompressed DT fuel is achieved with the beam powers much higher than the values presently in consideration.

  1. Gröbner bases statistics and software systems

    CERN Document Server

    2013-01-01

    The idea of the Gröbner basis first appeared in a 1927 paper by F. S. Macaulay, who succeeded in creating a combinatorial characterization of the Hilbert functions of homogeneous ideals of the polynomial ring. Later, the modern definition of the Gröbner basis was independently introduced by Heisuke Hironaka in 1964 and Bruno Buchberger in 1965. However, after the discovery of the notion of the Gröbner basis by Hironaka and Buchberger, it was not actively pursued for 20 years. A breakthrough was made in the mid-1980s by David Bayer and Michael Stillman, who created the Macaulay computer algebra system with the help of the Gröbner basis. Since then, rapid development on the Gröbner basis has been achieved by many researchers, including Bernd Sturmfels. This book serves as a standard bible of the Gröbner basis, for which the harmony of theory, application, and computation are indispensable. It provides all the fundamentals for graduate students to learn the ABC’s of the Gröbner basis, requiring no speci...

We study the stability of various quantities measuring the singularity (dimension, Hölder exponent etc) of the topological conjugacy between and T when . This is a well-understood problem for maps with finitely-many branches, and the quantities are stable for small ɛ, that is, they converge to their expected values if . For the infinite branch case their stability might be expected to fail, but we prove that even in the infinite branch case the quantity is stable under some natural regularity assumptions on and T (under which, for instance, the Hölder exponent of fails to be stable). Our assumptions apply for example in the case of Gauss map, various Lüroth maps and accelerated Manneville-Pomeau maps when varying the parameter α. For the proof we introduce a mass transportation method from the cusp that allows us to exploit thermodynamical ideas from the finite branch case. Dedicated to the memory of Bernd O Stratmann

    Full Text Available Jörn Kircher, Christoph Ziskoven, Thilo Patzer, Daniela Zaps, Bernd Bittersohl, Rüdiger KrauspeUniversity Hospital, Orthopaedic Department, Heinrich-Heine University Düsseldorf, Düsseldorf, GermanyAbstract: The complete rupture of the pectoralis major tendon is an uncommon injury but has become increasingly common among athletes in recent years. This may be due to a higher number of individuals taking part in high-impact sports and weightlifting as well as the use of anabolic substances, which can make muscles and tendons vulnerable to injury. In recent literature, there are only few recommendations to rely on conservative treatment alone, but there are a number of reports and case series recommending early surgical intervention. Comparing the results of the two treatment regimens, there is clear evidence for a superior outcome after surgical repair with better cosmesis, better functional results, regaining of muscle power, and return to sports compared with the conservative treatment. In summary, anatomic surgical repair is the treatment of choice for complete acute ruptures of the pectoralis major tendon or muscle in athletes.Keywords: pectoralis major, rupture, athlete, conservative treatment, surgical treatment, steroid, tendon, sports injury

  17. The iconostasis in Dečani: the original painted programme and subsequent changes

    Full Text Available The history of the iconostasis in the central nave of the church in Dečani can be divided into two periods. The icons of Christ, the Mother of God, John the Baptist and St. Nicholas on the original altar screen, painted around 1343, were related to the relics of King Stefan Dečanski and with the wall painting in the church space in front of the altar. The removal of those icons at the end of the sixteenth century and their replacement with new ones explains the strengthening cult of St. Stefan Dečanski. In 1577 an icon of St. Stephen was placed over the king’s portrait depicted in the fourteenth century fresco painting, and by 1593/1594, the new despotic icons of Christ and the Virgin were painted for the iconostasis, then an expanded Deesis that was placed above them, with a large cross fixed on the top. The central icons were painted by the painter Longin, and the cross is attributed to Andreja, a painter known for his frescoes from the seventh and eighth decade of the seventeenth century.

  18. Modeling of the co-transport of cryoprotective agents in a porous medium as a model tissue.

    2003-01-01

    Cryopreservation is likely the choice for long-term preservation of natural and engineered tissues, and high concentration multiple cryoprotective agents (CPAs) are usually used in such a process. To achieve high cell viability after cryopreservation, cells at all locations within the tissue must be protected properly by the CPAs during freezing. It is hence essential to know the distribution and concentration of CPAs within the tissue during multiple-CPA addition, to maximize cell survival and minimize tissue damage. In this work, a model to describe the CPA transport during multiple-CPA addition in a one-dimensional porous medium, as a simplified model of living tissue, was developed on the basis of the Maxwell-Stefan (M-S) equations. The UNIFAC and UNIQUAC models were used to evaluate the activity coefficients, and the Siddiqi-Lucas correlation was used for estimation of Maxwell-Stefan diffusivities. Simulations were carried out to examine the effect of temperature, tissue property, CPA type and the interactions between solutes on the CPA transport within construct during the CPA addition. It was found that these parameters, especially the interactions between the different CPA molecules, which was neglected before, significantly affect the transport of each individual CPA component. It is hence concluded that the traditional single-component analysis on the CPA diffusion is not adequate to quantify the multiple-CPA distribution in the tissue, particularly when the CPA concentrations are relatively high.

Estes, na maioria, foram refugiados do nazismo como entre outros Stefan Zweig, Richard Katz, Wolfgang Hoffmann-Harnisch, Frank Arnau e Marte Brill. Quanto ao imaginário acerca do Brasil descrito por Jacob percebe-se que ele como tantos outros autores também viu no Brasil um "país de um futuro" (como o chamou e uma "democracia racial" pretensa existente no país. Apesar disso, não desistiu de desmascarar a cordialidade brasileira proverbial como sendo apenas disfarce e de indicar problemas existentes como a questão da política quanto ao café e as consequencias negativas do nacionalismo, fomentado pelo regime Vargas.

    Modeling and CFD simulation of a three-dimensional microreactor includes thirteen structured parallel channels is performed to study the hydrogen production via methanol steam reforming reaction over a Cu/ZnO/Al2O3 catalyst. The well-known Langmuir-Hinshelwood macro kinetic rate expressions reported by Peppley and coworkers [49] are considered to model the methanol steam reforming reactions. The effects of inlet steam to methanol ratio, pre-heat temperature, channels geometry and size, and the level of external heat flux on the hydrogen quality and quantity (i.e., hydrogen flow rate and CO concentration) are investigated. Moreover, the possibility of reducing the CO concentration by passing the reactor effluent through a water gas shift channel placed in series with the methanol reformer is studied. Afterwards, the simulation results are compared with the experimental data reported in the literature considering two different approaches of mixture-averaged and Maxwell-Stefan formulations to evaluate the diffusive flux of mass. The results indicate that the predictions of the Maxwell-Stefan model is in better agreement with experimental data than mixture-averaged one, especially at the lower feed flow rates.

    The equation of state of the SU(3) Yang-Mills theory is determined in the deconfined phase with a precision of about 0.5%. The calculation is carried out by numerical simulations of lattice gauge theory with shifted boundary conditions in the time direction. At each given temperature, up to 230Tc with Tc being the critical temperature, the entropy density is computed at several lattice spacings so to be able to extrapolate the results to the continuum limit with confidence. Taken at face value, above a few Tc the results exhibit a striking linear behaviour in ln ⁡(T /Tc)-1 over almost 2 orders of magnitude. Within errors, data point straight to the Stefan-Boltzmann value but with a slope grossly different from the leading-order perturbative prediction. The pressure is determined by integrating the entropy in the temperature, while the energy density is extracted from Ts = (ɛ + p). The continuum values of the potentials are well represented by Padé interpolating formulas, which also connect them well to the Stefan-Boltzmann values in the infinite temperature limit. The pressure, the energy and the entropy densities are compared with results in the literature. The discrepancy among previous computations near Tc is analyzed and resolved thanks to the high precision achieved.

    The aim of this book is to present and analyze philosophical conceptions concerning mathematics and logic as formulated by Polish logicians, mathematicians and philosophers in the 1920s and 1930s. It was a remarkable period in the history of Polish science, in particular in the history of Polish logic and mathematics. Therefore, it is justified to ask whether and to what extent the development of logic and mathematics was accompanied by a philosophical reflection. We try to answer those questions by analyzing both works of Polish logicians and mathematicians who have a philosophical temperament as well as their research practice. Works and philosophical views of the following Polish scientists will be analyzed: Wacław Sierpiński, Zygmunt Janiszewski, Stefan Mazurkiewicz, Stefan Banach Hugo Steinhaus, Eustachy Żylińsk and Leon Chwistek, Jan Łukasiewicz, Zygmunt Zawirski, Stanisław Leśniewski, Tadeusz Kotarbiński, Kazimierz Ajdukiewicz, Alfred Tarski, Andrzej Mostowski and Henryk Mehlberg, Jan Sleszyńs...

  5. Evidence of high-elevation amplification versus Arctic amplification.

    Elevation-dependent warming in high-elevation regions and Arctic amplification are of tremendous interest to many scientists who are engaged in studies in climate change. Here, using annual mean temperatures from 2781 global stations for the 1961-2010 period, we find that the warming for the world's high-elevation stations (>500 m above sea level) is clearly stronger than their low-elevation counterparts; and the high-elevation amplification consists of not only an altitudinal amplification but also a latitudinal amplification. The warming for the high-elevation stations is linearly proportional to the temperature lapse rates along altitudinal and latitudinal gradients, as a result of the functional shape of Stefan-Boltzmann law in both vertical and latitudinal directions. In contrast, neither altitudinal amplification nor latitudinal amplification is found within the Arctic region despite its greater warming than lower latitudes. Further analysis shows that the Arctic amplification is an integrated part of the latitudinal amplification trend for the low-elevation stations (≤500 m above sea level) across the entire low- to high-latitude Northern Hemisphere, also a result of the mathematical shape of Stefan-Boltzmann law but only in latitudinal direction.

Morphology, functionalization, purity, molecular mass and thermal stability of the graphene nanomaterial and/or the poly(ethylene glycol were characterized. Design parameters of NePCMs were defined on the basis of a temporal stability study of nanoplatelet dispersions using dynamic light scattering. Influence of graphene loading on solid-liquid phase change transition temperature, latent heat of fusion, isobaric heat capacity, thermal conductivity, density, isobaric thermal expansivity, thermal diffusivity and dynamic viscosity were also investigated for designed dispersions. Graphene nanoplatelet loading leads to thermal conductivity enhancements up to 23% while the crystallization temperature reduces up to in 4 K. Finally, the heat storage capacities of base fluid and new designed NePCMs were examined by means of the thermophysical properties through Stefan and Rayleigh numbers. Functionalized graphene nanoplatelets leads to a slight increase in the Stefan number.

    The conventional Tolman temperature based on the assumption of the traceless condition of energy-momentum tensor for matter fields is infinite at the horizon if Hawking radiation is involved. However, we note that the temperature associated with Hawking radiation is of relevance to the trace anomaly, which means that the traceless condition should be released. So, a trace anomaly-induced Stefan-Boltzmann law is newly derived by employing the first law of thermodynamics and the property of the temperature independence of the trace anomaly. Then, the Tolman temperature is quantum-mechanically generalized according to the anomaly-induced Stefan-Boltzmann law. In an exactly soluble model, we show that the Tolman factor does not appear in the generalized Tolman temperature which is eventually finite everywhere, in particular, vanishing at the horizon. It turns out that the equivalence principle survives at the horizon with the help of the quantum principle, and some puzzles related to the Tolman temperature are also resolved.

    2016-01-01

    Full Text Available This study presents a numerical analysis of the melting process of phase change materials (PCMs within a latent heat thermal energy storage (LHTES system employing zigzag plate. The numerical model used NaCl-MgCl2 mixture as PCMs and hot air as heat transfer fluid (HTF. An experimental system was built to validate the model, and the experimental data agrees reasonably well with the simulation results. The simulation results revealed the effects of the Reynolds and Stefan numbers and the surface topography of the zigzag plate on the charging process. Besides, the effect of the relationship between Reynolds and Stefan numbers on the charging process under a new boundary condition employing a fixed input power was studied. It is found that by modifying the shape of the zigzag plate surface it is feasible to enhance the heat transfer of the LHTES unit remarkably. The melting rate of PCMs increases with the value of Ste or Re numbers with only one of them changing; however, the melting rate of PCMs decreases with the increasing Ste (or decreasing Re in a fixed input power condition.

  11. Judicial privilgies of Saxons in mixed disputes in Medieval Serbia

    Directory of Open Access Journals (Sweden)

    Katančević Andreja

    2015-01-01

    Full Text Available Based on the contemporary testimonies, wealth of the Serbian medieval kings was significantly increased by exploitation of number of precious metal mines that existed in their realm. Beginnings of the mine exploitation in medieval Serbia are related to the settlements of Saxon miners. Saxons were mining experts in medieval Europe who worked in distant mines far away from their homeland Saxony. They worked in this profitable mining business not only in Serbia, but also in Bohemia, Hungary (Transylvania and modern Slovakia and Bosnia. The settlement of Saxons in Serbia occurred in time of the reign of King Stefan Uros I (1234-1276. Although without preserved sources which could directly support this thesis, Serbian historiography advocates that certain privileges were granted to the Roman Catholic Saxons at the time of their migration in orthodox Serbia. It appears that these privileges included self-government, freedom of religion, and mining concessions. Also judicial privileges are often mentioned in historiography especially the right of Saxons to one half of the members of their ethnicity in judicial collegium and jury in the case of a dispute with member of another ethic group. This paper attempts to test the thesis related to composition of mixed courts and juries by applying historical method, and linguistic, systemic and historical interpretation of the sources such as King's Charters issued to Dubrovnik, Dusan's Code and Despot Stefan's Mining Code.

  13. Final report on LDRD project: A phenomenological model for multicomponent transport with simultaneous electrochemical reactions in concentrated solutions

    2000-01-01

    A phenomenological model was developed for multicomponent transport of charged species with simultaneous electrochemical reactions in concentrated solutions, and was applied to model processes in a thermal battery cell. A new general framework was formulated and implemented in GOMA (a multidimensional, multiphysics, finite-element computer code developed and being enhanced at Sandia) for modeling multidimensional, multicomponent transport of neutral and charged species in concentrated solutions. The new framework utilizes the Stefan-Maxwell equations that describe multicomponent diffusion of interacting species using composition-insensitive binary diffusion coefficients. The new GOMA capability for modeling multicomponent transport of neutral species was verified and validated using the model problem of ternary gaseous diffusion in a Stefan tube. The new GOMA-based thermal battery computer model was verified using an idealized battery cell in which concentration gradients are absent; the full model was verified by comparing with that of Bernardi and Newman (1987) and validated using limited thermal battery discharge-performance data from the open literature (Dunning 1981) and from Sandia (Guidotti 1996). Moreover, a new Liquid Chemkin Software Package was developed, which allows the user to handle manly aspects of liquid-phase kinetics, thermodynamics, and transport (particularly in terms of computing properties). Lastly, a Lattice-Boltzmann-based capability was developed for modeling pore- or micro-scale phenomena involving convection, diffusion, and simplified chemistry; this capability was demonstrated by modeling phenomena in the cathode region of a thermal battery cell.

  14. Preparing for a Career in Industrial Physics

    Science.gov (United States)

    Meisner, Gregory

    My career in physics has been extremely rewarding. My career path, however, was not what I imagined it would be when I started college. I thought I would be a math major and eventually a university math professor. A big challenge of my college and graduate school experience, aside from actually learning physics, was to find out what I was most passionate about and then to pursue that endeavor wherever it led. The graduate school part of my career path wound its way into experimental condensed matter physics, but I still expected that I would remain in academia. Along the way, I learned a lot from many people, worked hard to accomplish good results, and availed myself of unexpected opportunities for professional development and career advancement. One piece of advice that resonated with me was to always try to be learning something new, and I did manage to do that throughout my career: in graduate school and as a post doc I studied low temperature experimental physics and superconductivity, whereas my areas of research as an industrial physicist at GM R&D were permanent magnets, then hydrogen storage materials for fuel cell vehicle applications, and finally thermoelectric materials and devices for waste exhaust gas heat recovery. The best piece of advice, which has served me well along my career path and my life path in general, was in the remarks astronaut Katherine Sullivan gave at my PhD graduation ceremony at UCSD in 1982. Her advice was captured in the word ``quality''. Specifically, always strive for the highest quality in everything you do. Another impactful word, which was a favorite of my thesis advisor, Bernd Matthias, is ``serendipity''. Specifically, you need to know how to recognize and capitalize on unexpected or unusual occurrences - they may be the best stepping stones you will have along your career path. My presentation will discuss a few specifics of how I prepared myself for a career in industrial physics.

Exercise-induced asthma-like symptoms and asthma are also frequently seen in highly trained athletes. Exercise-induced asthma (EIA and exercise-induced bronchoconstriction (EIB are found in 8%–10% of healthy school-aged children and in 35% of children with asthma. Highly increased ventilation, inhalation of cold, dry air and air pollutants (eg, chlorine are thought to be important triggers for EIA and EIB. EIA is often experienced concurrently with vocal cord dysfunction, which needs to be considered during the differential diagnosis. The pharmacological treatment of EIA is similar to the treatment of asthma in nonexercising adolescents. The therapy is based on anti-inflammatory drugs (eg, inhaled glucocorticosteroids and bronchodilators (eg, β2-agonists. The treatment of EIB is comparable to the treatment of EIA and leukotriene modifiers offer a new and promising treatment option, particularly in EIB. Generally, athletes may not use β2-agonists according to the prohibited list of the World Anti-Doping Agency (WADA. However, the WADA list contains specific β2-agonistic substances that are permitted to be used by inhalation.Keywords: exercise-induced asthma, exercise-induced bronchospasm, adolescents, asthma, athletes

The main purpose is to evaluate the benefit-risk profile of fingolimod, the first oral compound available for treatment of multiple sclerosis (MS and just recently approved by the European authorities. The authors place this evaluation in the context of the known safety and efficacy profile of established compounds for therapy of MS to outline the current and future potential of fingolimod. The authors conclude that only long-term safety data from post-marketing surveillance plans, together with additional head-to-head studies, would allow evidence-based treatment decisions. Furthermore, risk-profile analyses including patient history, exposure data to certain pathogens, and genetic analyses may potentially help to choose the right drug for individual patients in the future. Until these approaches toward an individualized medicine have been validated, treatment decisions for one or the other compound will have to be based partly on class IV evidence. Therefore, a close dialog with the well-informed patient, secured by effective risk mitigation plans, is required to choose the compound.Keywords: FTY720, oral drug, spingosine 1-phosphate receptor

Statins seem to exert an inhibitory effect on MMP activity in the aortic wall. No data exist on the effect of statins on serum activity of MMPs and inflammatory cytokines (interleukins, IL.Methods: The serum activities of MMP2 and MMP9, osteoprotegerin (OPG, and IL6 and IL10 in 63 patients undergoing elective infrarenal aneurysm repair were measured on the day before surgery. Levels were correlated to statin therapy and aneurysm diameter.Results: There was no significant difference between the two groups in the activity of circulating levels of MMP2/9, OPG, and IL6/10 in patients with infrarenal aortic aneurysm. IL6 levels in patients with AAA larger than 6 cm were significantly elevated; differences in serum activities of MMP2/9, OPG, and IL10 were not related to AAA diameter.Conclusion: Serum activities of MMP2/9, OPG, and IL6/10 are not correlated to statin therapy; IL6 levels are higher in patients with large aneurysms. Hence the effect of statin therapy in the treatment of aneurismal disease remains to be elucidated.Keywords: biomarkers, aneurismal disease, statin therapy

    The number of eHealth interventions in the management of chronic diseases such as atopic dermatitis (AD) is growing. Despite promising results, the implementation and use of these interventions is limited. This study aimed to assess opinions of the most important stakeholders influencing the implementation and use of eHealth services in daily dermatology practice. The perspectives of health care professionals and patients towards the implementation and use of eHealth services in daily practice were assessed by using a mixed method design. A cross-sectional survey based on the eHealth implementation toolkit (eHit) was conducted to explore factors influencing the adoption of eHealth interventions offering the possibility of e-consultations, Web-based monitoring, and Web-based self-management training among dermatologists and dermatology nurses. The perspectives of patients with atopic dermatitis (AD) regarding the use of eHealth services were discussed in an online focus group. Health care professionals (n=99) and patients (n=9) acknowledged the value of eHealth services and were willing to use these digital tools in daily dermatology practice. Key identified barriers (statements with dermatology practice. However, some important barriers were identified that might be useful in addressing the implementation strategy in order to enhance the implementation success of eHealth interventions in dermatology. ©Lieneke FM Ariens, Florine ML Schussler-Raymakers, Cynthia Frima, Annebeth Flinterman, Eefje Hamminga, Bernd WM Arents, Carla AFM Bruijnzeel-Koomen, Marjolein S de Bruin-Weller, Harmieke van Os-Medendorp.

Recent studies indicate that once-daily antiretroviral regimens improve adherence, especially in antiretroviral-naïve patients and in difficult-to-treat populations, such as the homeless or marginally housed. However, there are potential risks with the higher peak and lower trough plasma drug concentrations that may result from certain once-daily formulations. Due to the multifactorial and complex nature of adherence behavior, clinicians’ efforts to improve patient adherence should not be limited to prescribing once-daily regimens, but should also consider social support, side effect management, and adherence support tools, such as pillbox organizers and other targeted interventions. Additional research will clarify the benefits of once-daily and fixed-dose combination regimens on clinical and virologic outcomes. Comprehensive cost-benefit analysis of regimen simplification could help facilitate evidence-based decisions regarding antiretroviral regimen choices.Keywords: regimen adherence, regimen simplification, health care costs, fixed-dose combination, once-daily antiretroviral drugs

    The effects of soil property uncertainties on permafrost thaw projections are studied using a three-phase subsurface thermal hydrology model and calibration-constrained uncertainty analysis. The null-space Monte Carlo method is used to identify soil hydrothermal parameter combinations that are consistent with borehole temperature measurements at the study site, the Barrow Environmental Observatory. Each parameter combination is then used in a forward projection of permafrost conditions for the 21st century (from calendar year 2006 to 2100) using atmospheric forcings from the Community Earth System Model (CESM) in the Representative Concentration Pathway (RCP) 8.5 greenhouse gas concentration trajectory. A 100-year projection allows for the evaluation of predictive uncertainty (due to soil property (parametric) uncertainty) and the inter-annual climate variability due to year to year differences in CESM climate forcings. After calibrating to measured borehole temperature data at this well-characterized site, soil property uncertainties are still significant and result in significant predictive uncertainties in projected active layer thickness and annual thaw depth-duration even with a specified future climate. Inter-annual climate variability in projected soil moisture content and Stefan number are small. A volume- and time-integrated Stefan number decreases significantly, indicating a shift in subsurface energy utilization in the future climate (latent heat of phase change becomes more important than heat conduction). Out of 10 soil parameters, ALT, annual thaw depth-duration, and Stefan number are highly dependent on mineral soil porosity, while annual mean liquid saturation of the active layer is highly dependent on the mineral soil residual saturation and moderately dependent on peat residual saturation. By comparing the ensemble statistics to the spread of projected permafrost metrics using different climate models, we quantify the relative magnitude of soil

    In the early 80's the SMUP computer code was developed at the Jozef Stefan Institute for simulation of two-phase flow in steam generators. It was suitable only for steady-state problems and was unable to simulate transient behavior. In this paper, efforts are presented to find suitable numerical method to renew the old SMUP computer code. The obsolete numerical code has to be replaced with a more efficient one that would be able to treat time-dependent problems. It also has to ensure accurate solution during shock propagation. One-dimensional shock propagation in a tube were studied at zero viscosity. To simplify the equation of state the ideal gas was chosen as a working fluid. Stability margins in the form of transport matrix eigenvalues were calculated. Results were found to be close to those already published.(author)

    Full Text Available Malgrado il pregiudizio secondo il quale la poesia in generale e la Divina Commedia in particolare sarebbero intraducibili, quest'ultima dal Settecento in poi è stata tradotta in tedesco – sia parzialmente che completamente – più di centosettanta volte. Non solo i romantici ma anche i filologi dell'Ottocento hanno contribuito in maniera decisiva a questa intensa ricezione. Nel Novecento la pratica della traduzione è stata portata avanti da due grandi poeti: Stefan George e Rudolf Borchardt. Un'analisi selettiva del primo canto dell’Inferno e delle traduzioni di George e Borchardt mostrerà alcune trasformazioni specifiche del testo dantesco a seconda delle scelte linguistiche dei due poeti.

    Nuclear Training Centre Milan Copic at Jozef Stefan Institute in Ljubljana is performing extensive public information activities, focused mainly on elementary and high schools in Slovenia. There are over 7000 visitors yearly. Every year in the spring we ask several hundred of visitors the same set of questions about their knowledge and opinion about nuclear energy. They are polled before they listen to the lecture or visit the exhibition. In that way we are trying to obtain their opinion based on the knowledge they obtain in everyday life. In the paper the results of this year's poll are presented and compared with the previous years. No significant changes in public opinion were observed this year. Favourable attitude towards NPP Krsko, which could be observed in the last years, is maintained. On the other hand, misconceptions about radioactive waste repositories and danger of radioactive waste remain very high. (author)

    2002-01-01

    In the early part of the 20th century, the pioneers of radioactivity research, led by Marie Curie, Ernest Rutherford and Stefan Meyer, formed a Commission internationale des étalons de radium. The Commission made arrangements for the preparation and intercomparisons of the international standards of radium, which were identified as the Paris standard and the Vienna standard. Otto Hönigschmid from Vienna prepared a first set of international secondary standards in 1912 and a second set in 1934. In both instances, these secondary standards were compared by gamma-ray measurements with the Paris and Vienna standards. The usage of these international standards of radium in the 20th century is described.

    Public information is one of the permanent activities of the Nuclear Training Centre Milan Copic at Jozef Stefan Institute in Ljubljana. It is focused on youngsters from elementary and high schools in Slovenia that visit the Centre as organized groups. Every year in the spring since 1993 some 800 youngsters are polled with basically the same set of questions inquiring about their knowledge and opinions on nuclear energy. Polling is performed at the beginning of the visit to obtain results based on information from everyday life. In the paper the results of this year's poll are presented and compared with the previous years. The attitude towards NPP Krsko is still favourable but the support has unexpectedly dropped from 83% to 73%. Misconceptions about dangers of nuclear energy and radioactive waste still remain high.

  17. Modeling Ignition of HMX with the Gibbs Formulation

    Science.gov (United States)

    Lee, Kibaek; Stewart, D. Scott

    2017-06-01

    We present a HMX model with the Gibbs formulation in which stress tensor and temperature are assumed to be in local equilibrium, but phase/chemical changes are not assumed to be in equilibrium. We assume multi-components for HMX including beta- and delta-phase, liquid, and gas phase of HMX and its gas products. Isotropic small strain solid model, modified Fried Howard liquid EOS, and ideal gas EOS are used for its relevant component. Phase/chemical changes are characterized as reactions and are in individual reaction rate. Maxwell-Stefan model is used for diffusion. Excited gas products in the local domain lead unreacted HMX solid to the ignition event. Density of the mixture, stress, strain, displacement, mass fractions, and temperature are considered in 1D domain with time histories.

    CERN Document Server

    Prüss, Jan

    2016-01-01

    In this monograph, the authors develop a comprehensive approach for the mathematical analysis of a wide array of problems involving moving interfaces. It includes an in-depth study of abstract quasilinear parabolic evolution equations, elliptic and parabolic boundary value problems, transmission problems, one- and two-phase Stokes problems, and the equations of incompressible viscous one- and two-phase fluid flows. The theory of maximal regularity, an essential element, is also fully developed. The authors present a modern approach based on powerful tools in classical analysis, functional analysis, and vector-valued harmonic analysis. The theory is applied to problems in two-phase fluid dynamics and phase transitions, one-phase generalized Newtonian fluids, nematic liquid crystal flows, Maxwell-Stefan diffusion, and a variety of geometric evolution equations. The book also includes a discussion of the underlying physical and thermodynamic principles governing the equations of fluid flows and phase transitions...

  19. Mechanics of the Separating Surface for a Two-Phase Co-current Flow in a Porous Medium

    DEFF Research Database (Denmark)

    Shapiro, Alexander A.

    2016-01-01

    A mechanical description of an unsteady two-phase co-current flow in a porous medium is developed based on the analysis of the geometry and motion of the surface separating the two phases. It is demonstrated that the flow should be considered as essentially three-dimensional, even if the phase...... velocities are co-directed, since the phase interface is on average inclined to the direction of the flow. Kinematics of the flow is described, distinguishing between the average velocities of the bulk phases and their velocity near the interface between them. Dynamics of the flow is analyzed by means...... of the extended Maxwell-Stefan formalism, as in our previous paper (Shapiro 2015). Force balances are formulated in the directions parallel and orthogonal to the flow. A complete system of the flow equations, generalizing the traditional Buckley–Leverett and Rappoport–Leas system, is derived. Sample computations...

    2016-01-01

    The TRIGA Mark II research reactor at Jožef Stefan Institute (JSI) in Ljubljana Slovenia has been playing an important role in developing nuclear technology and safety culture in Slovenia. In the 1970s-1980s the reactor was extensively used for production of radioactive isotopes. Since then the reactor has been extensively used for various applications, such as: irradiation of various samples, training and education, verification and validation of nuclear data and computer codes, testing and development of experimental equipment used for core physics tests at a nuclear power plant. The paper describes the aforementioned activities proving that even such small reactors are still indispensable in nuclear science and technology. (author)

    Linetty, Jakub

    2015-01-01

    Prehistoric archaeology constituted an important topic in the writings of Karol Libelt during the final stage of his work. As a result of several years' research and bringing up this subject in his texts, Libelt made notable achievements in the field of prehistoric archaeology. The most important of them are: description of archaeological discoveries in Czeszewo, participation in a dispute over prehistoric chronology with Stefan Pawlicki in 1871, and also one of the first descriptions of the Stone Age in the Polish literature. Thus Libelt should be considered as a pioneer in prehistoric research, particularly the Stone Age, in Poland. Apart from that, among his undoubted achievements was propagation of the theory of evolution, although with reservations, during the earliest stage of Darwinism's reception in Poland.

  3. Study of conversion of ammonia from urea water solution droplets using CFD

    Jyothis, K.; Vikas, R.

    2017-09-01

    This paper deals with the numerical analysis of the spray behaviour of urea water solution (UWS) droplets used in Selective catalytic reduction (SCR) process. The study uses the ANSYS-Fluent-14 as a basic framework for numerical simulations. The evaporation modelling is based on multi-component droplet evaporation approach along with the consideration of Stefan flow. The urea decomposition treated as direct thermolysis approach, where the modelling is based on the single kinetic rate approach by the proper fitting of pre-exponent. This developed model was used for spray simulation of UWS droplet evaporation to determine the urea to ammonia conversion efficiency. The obtained spray simulation results were compared with the available experimental data. The comparison shows the pre-exponent developed in the study is suitable for direct thermolysis approach to get promising results in determining the ammonia conversion efficiency.

  5. The black hole quantum atmosphere

    Science.gov (United States)

    Dey, Ramit; Liberati, Stefano; Pranzetti, Daniele

    2017-11-01

    Ever since the discovery of black hole evaporation, the region of origin of the radiated quanta has been a topic of debate. Recently it was argued by Giddings that the Hawking quanta originate from a region well outside the black hole horizon by calculating the effective radius of a radiating body via the Stefan-Boltzmann law. In this paper we try to further explore this issue and end up corroborating this claim, using both a heuristic argument and a detailed study of the stress energy tensor. We show that the Hawking quanta originate from what might be called a quantum atmosphere around the black hole with energy density and fluxes of particles peaked at about 4 MG, running contrary to the popular belief that these originate from the ultra high energy excitations very close to the horizon. This long distance origin of Hawking radiation could have a profound impact on our understanding of the information and transplanckian problems.

  6. New laser power sensor using diamagnetic levitation

    Science.gov (United States)

    Pinot, P.; Silvestri, Z.

    2017-08-01

    This paper presents a preliminary study of an elementary device consisting of a small plate made from pyrolytic carbon levitated above a magnet array which is sensitive to any irradiating laser power. This device might provide an interesting alternative to power meters based on thermal measurement techniques via the Stefan-Boltzmann law or the photon-electron interaction. We show that the photo-response of a pyrolytic carbon plate in terms of levitation height versus irradiation power in the range of 20 mW to 1 W is sufficiently linear, sensitive, and reproducible to be used as a laser power sensor. The elevation height change as a function of irradiance time appears to be a suitable measurement parameter for establishing a relation with the irradiating laser power. The influence of some quantities affecting the measurement results has been highlighted. The study demonstrates that such a device should prove useful for applications in metrology, industry, or emerging technologies.

    A suite of natural matrix reference materials (RMs) were used to assess the quality of analytical results obtained by k 0 -instrumental neutron activation analysis (k 0 -INAA) at the Jozef Stefan Institute (IJS). Five certified reference materials (CRMs) from the Institute for Reference Materials and Measurements (IRMM), two standard reference materials (SRMs) from the National Institute of Standards and Technology (NIST), three RMs from the International Atomic Energy Agency (IAEA) and one RM from IJS were analyzed. Altogether, results for twenty-four elements in inorganic matrices and twenty-nine elements in organic matrices, obtained by k 0 -INAA, were compared to certified values. Results obtained show good agreement with certified or assigned values except for Fe, La, Nd, Sm and U in inorganic matrices, and Ag, Al and Cr in organic matrices. (author)

  10. Isothermal temperature reactivity coefficient measurement in TRIGA reactor

    International Nuclear Information System (INIS)

    Zagar, T.; Ravnik, M.; Trkov, A.

    2002-01-01

    Direct measurement of an isothermal temperature reactivity coefficient at room temperatures in TRIGA Mark II research reactor at Jozef Stefan Institute in Ljubljana is presented. Temperature reactivity coefficient was measured in the temperature range between 15 o C and 25 o C. All reactivity measurements were performed at almost zero reactor power to reduce or completely eliminate nuclear heating. Slow and steady temperature decrease was controlled using the reactor tank cooling system. In this way the temperatures of fuel, of moderator and of coolant were kept in equilibrium throughout the measurements. It was found out that TRIGA reactor core loaded with standard fuel elements with stainless steel cladding has small positive isothermal temperature reactivity coefficient in this temperature range.(author)

    2012-01-01

    Full Text Available On the façade of the church of the Presentation of the Virgin, in Lipljan, the damaged depictions of two rulers were discovered under a more recent layer of fresco mortar. The depictions can be identified as portraits of the Serbian king and the emperor Stefan Dušan (1331-1355 and his wife Jelena. That provides the basis for the more reliable dating of the original wall painting in the interior of the church. For their part, the stylistic characteristics of that expressionistic painting suggest that the original Lipljan frescoes came into being around the mid-fourteenth century. Probably, they were executed by the same workshop that did the frescoes in the Church of St. Peter near Unjemir in Metohia, not very far from Lipljan.

    2012-04-01

    It is shown that thermally excited plasmon-polariton modes can strongly mediate, enhance, and tune the near-field radiation transfer between two closely separated graphene sheets. The dependence of near-field heat exchange on doping and electron relaxation time is analyzed in the near infrared within the framework of fluctuational electrodynamics. The dominant contribution to heat transfer can be controlled to arise from either interband or intraband processes. We predict maximum transfer at low doping and for plasmons in two graphene sheets in resonance, with orders-of-magnitude enhancement (e.g., 102 to 103 for separations between 0.1 μm and 10 nm) over the Stefan-Boltzmann law, known as the far-field limit. Strong, tunable, near-field transfer offers the promise of an externally controllable thermal switch as well as a novel hybrid graphene-graphene thermoelectric/thermophotovoltaic energy conversion platform.

    Almost all the analyses of tritium in Slovenia have been performed by the tritium laboratory at the Jozef Stefan Institute. Nearly 90 % of its measurements have been covered by two national programs, both approved by the Slovenian Nuclear Safety Administration: the radioactive monitoring program in the environs of Krsko Nuclear Power Plant (KNPP) and the program of global radioactive contamination monitoring in the environment. These programs include samples of groundwaters, surface waters, precipitation and drinking waters, as well as liquid and gaseous effluents from KNPP. Tritium was determined in some research projects and in hydrological studies of thermal waters, groundwater and coalmine waters. Tritium in the Karst region was mapped as well as the springs of entire territory of Slovenia. Around 5500 samples have been analyzed up to 2004

    2013-12-01

    Full Text Available The problem of determination of the phase-change boundary position at the mathematical modeling of continuous ingot temperature field is considered. The description of the heat transfer process takes into account the dependence of the thermal physical characteristics on the temperature, so that the mathematical model is based on the nonlinear partial differential equations. The boundary position between liquid and solid phase is given by the temperatures equality condition and the Stefan condition for the two-dimensional case. The new method of calculation of the phase-change boundary position is proposed. This method based on the finite-differences with using explicit schemes and on the iteration method of solving of non-linear system equations. The proposed method of calculation is many times faster than the real time. So that it amenable to be used for model predictive control of continuous semifinished product solidification.

    Science.gov (United States)

    Husain, Viqar; Seahra, Sanjeev S.; Webster, Eric J.

    2013-07-01

    Quantization prescriptions that realize generalized uncertainty relations are motivated by quantum gravity arguments that incorporate a fundamental length scale. We apply two such methods, polymer and deformed Heisenberg quantization, to scalar field theory in Fourier space. These alternative quantizations modify the oscillator spectrum for each mode, which in turn affects the blackbody distribution. We find that for a large class of modifications, the equation of state relating pressure P and energy density ρ interpolates between P=ρ/3 at low T and P=2ρ/3 at high T, where T is the temperature. Furthermore, the Stefan-Boltzman law gets modified from ρ∝T4 to ρ∝T5/2 at high temperature. This suggests an effective reduction to 2.5 spacetime dimensions at high energy.

    2012-12-01

    Full Text Available This article addresses key concepts such as sign, system and complexity in order to approach transmedia storytelling and better understand its intricate nature. The theoretical framework chosen to investigate transmedia storytelling meanders is Semiotics by Charles Sanders Peirce (1839-1914 and General Systems Theory by Mario Bunge (1919-. The complexity of transmedia storytelling is not simply the one of the signs of the works included in a transmedia franchise. It also includes the complexity of the dispositions of users/consumers/players as interpreters of semiotic elements (e.g. characters, themes, environments, events and outcomes presented by transmedia products. It extends further to the complexity of social, cultural, economical and political constructs. The German transmedia narrative The Ultimate SuperHero-Blog by Stefan Gieren and Sofia’s Diary, a Portuguese multiplatform production by BeActive, are presented as examples of closed and open system transmedia storytelling respectively.

    International Nuclear Information System (INIS)

    Uchibori, Akihiro; Ohshima, Hiroyuki

    2008-01-01

    A numerical analysis method for melting/solidification phenomena has been developed to evaluate a feasibility of several candidate techniques in the nuclear fuel cycle. Our method is based on the eXtended Finite Element Method (X-FEM) which has been used for moving boundary problems. Key technique of the X-FEM is to incorporate signed distance function into finite element interpolation to represent a discontinuous gradient of the temperature at a moving solid-liquid interface. Construction of the finite element equation, the technique of quadrature and the method to solve the equation are reported here. The numerical solutions of the one-dimensional Stefan problem, solidification in a two-dimensional square corner and melting of pure gallium are compared to the exact solutions or to the experimental data. Through these analyses, validity of the newly developed numerical analysis method has been demonstrated. (author)

    Nuclear components are under strict supervision of operators and safety authorities. The Reactor Centre of the Jožef Stefan Institute decided to make an inspection of its TRIGA Mark II research reactor to verify the conditions for long-term future operation within the on-going periodic safety review. Two main inspection methods were used: ultrasonic and visual inspection. Ultrasonic inspection was selected to prove that there is no significant reduction of wall thickness anywhere in the tank. The inspection confirmed that the reactor tank has not been degraded or corroded. In the future such inspection will take place every 10 years within the periodic safety review in order to monitor every 10 years the reactor tanks condition. (author)

    Ziani Abderrahmane

    2009-01-01

    Full Text Available During the formation of the electric arc at the opening of a high voltage circuit breaker, the generated plasma will be the seat of a very important thermal exchange. Models founded only on conduction and convection thermal transfers don't reproduce the whole thermal exchanges that are governing the extinction process. This paper is devoted to the development of a model of the electric arc extinction in a high voltage circuit breaker taking in account the thermal radiation of the plasma, in addition to the conduction and convection phenomena. The Stefan-Boltzman equation is coupled with the heat equation, and both equations are solved simultaneously in order to follow the evolution of the arc voltage and the conductance of the thermal plasma. The obtained results are found in good agreement with experimental recordings.

    2015-06-23

    Zeolitic imidazolate framework ZIF-8 has shown great potential for effective separation of hydrocarbon mixtures based on its intrinsic ultramicroporous feature. In order to explore the permeation and diffusion properties of hydrocarbons through ZIF-8 membrane, high-quality ZIF-8 membranes with a separation factor of ~90 for propylene/propane are successfully prepared via optimizing the activation processes. Single-component permeation data for hydrocarbons (C1–C4) through the improved ZIF-8 membrane are measured and analyzed by Maxwell-Stefan (MS) model to get the transport diffusivities of these hydrocarbons. The diffusivity values of hydrocarbon compare well with those obtained by other experimental techniques. Binary mixture permeation also can be well predicted through single-component adsorption parameters.

    2013-01-01

    Today, the industralized world lives in symbiosis with control systems: it depends on power distribution, oil production, public transport, automatic production lines. While the convenience is at hand, still too many control systems are designed without any security in mind, lack basic security protections, and are not even robust enough to withstand basic attacks.

    In Poland, medical embryology (both scientific research and teaching of the subject) has traditionally involved Chairs of Histology and Embryology rather than Obstetrics and Gynecology. Before World War II, the most buoyant centers for embryological research among the five universities at the time (in Warsaw, Krakow, Poznan, Lvov and Vilnius), were the Chairs of Embryology and Histology at Medical Faculties of the Jagiellonian University in Krakow and the University of Vilnius. After World War II, eleven Medical Academies (Universities of Medicine) came into being (Warsaw, Krakow, Poznan, Lodz, Gdansk, Bialystok, Bydgoszcz, Szczecin, Wroclaw, Katowice and Lublin). They conduct scientific research on normal development of the human embryo as well as teratology studies. In the XX century, eminent medicine-related embryologist included professors Emil Godlewski Jr., Stanislaw Hiller and Stefan Baginski.

  14. [Inadequate burials as an important factor in plague epidemic amongst Serbs in the Habsburg monarchy by the end of the 18th century: a historical analysis].

    Analysis of the archaic customs of burying the deceased in Srem, primarily amongst Serbs, in the second half of the 18th century is the essential part of the paper that aims at clarifying the consequences of this negative habit onto the spreading of plague epidemic. The Austrian Empire tried to stop and prevent the epidemic with an array of legal norms, but in practice, these orders were often not upheld. Serbian Metropolitans Pavle Nenadović and Stefan Stratimirović insisted on eradicating superstition and retrograde, often uncivilized actions in burial rituals, and they partially succeeded. The example of plague in Irig and the surroundings in 1795-1796 explicitly shows the hazardous effects of the inadequate attitude towards the deceased as one of the factors in spreading the epidemic. Using primary archives, and published sources, with adequate literature, authors depict this complex historical process.

  15. A model of river bank deformations under the simultaneous effect of waves from a hydropower plant and warming

    Directory of Open Access Journals (Sweden)

    E. Debolskaya

    2014-09-01

    Full Text Available This paper presents a mathematical model of the river bed deformations in permafrost areas. The deformations are caused by the influence of waves of various origins under an increase of the ambient temperature. The model system consists of an unsteady hydrodynamic module, a thermal module and a bed deformation module. The hydrodynamic module is based on the two-dimensional shallow water equations. The bed deformation module is based on the sediment mass balance conditions. The thermal module is based on the Stefan equation, which defines the "water–ice" boundary movement. We present two applications of the model in which the bed deformation is calculated for the alluvial channels with melting bed under the influences of waves of different duration and intensity. We compared the model predictions with the laboratory data, generally obtaining a good agreement between the two.

    In 43 places (23 schools, 3 kindergartens, 16 offices and one dwelling), indoor radon has been monitored as an intercomparison experiment, using α-scintillation cells (SC - Jožef Stefan Institute, Slovenia), various kinds of solid state nuclear track detectors (KfK - Karlsruhe Institute of Technology, Germany; UFO - National Institute of Radiological Sciences, Chiba, Japan; RET - University College Dublin, Ireland) and active electronic devices (EQF, Sarad, Germany). At the same place, the radon levels and, consequently, the effective doses obtained with different radon devices differed substantially (by a factor of 2 or more), and no regularity was observed as regards which detector would show a higher or lower dose.

    2014-10-01

    A novel method for alpha particle diagnostics is proposed. The theory of stimulated Raman scattering, SRS, of the fast wave and ion Bernstein mode, IBM, turbulence in multi-ion species plasmas, (Stefan University Press, La Jolla, CA, 2008). is utilized for the diagnostics of fast ions, (4)He (+2), in ITER plasmas. Nonlinear Landau damping of the IBM on fast ions near the plasma edge leads to the space-time changes in the turbulence level, (inverse alpha particle channeling). The space-time monitoring of the IBM turbulence via the SRS techniques may prove efficient for the real time study of the fast ion velocity distribution function, spatial distribution, and transport.

  20. Laser-Bioplasma Interaction: The Blood Type Transmutation Induced by Multiple Ultrashort Wavelength Laser Beams

    Science.gov (United States)

    Stefan, V. Alexander

    2015-11-01

    The interaction of ultrashort wavelength multi laser beams with the flowing blood thin films leads to the transmutation of the blood types A, B, and AB into O type. This is a novel mechanism of importance for the transfusion medicine. Laser radiation is in resonance with the eigen-frequency modes of the antigen proteins and forces the proteins to parametrically oscillate until they get kicked out from the surface. The stripping away of antigens is done by the scanning-multiple-lasers of a high repetition rate in the blue-purple frequency domain. The guiding-lasers are in the red-green frequency domain. The laser force, (parametric interaction with the antigen eigen-oscillation), upon the antigen protein molecule must exceed its weight. The scanning laser beam is partially reflected as long as the antigen(s) is not eliminated. The process of the protein detachment can last a few minutes.

    2017-10-01

    The novel study of the laser excitation-suppression of the brain waves is proposed. It is based on the pulsed-operated multi-photon fiber-laser interaction with the brain parvalbumin (PV) neurons. The repetition frequency matches the low frequency brain waves (5-100 Hz); enabling the resonance-scanning of the wide range of the PV neurons (the generators of the brain wave activity). The tunable fiber laser frequencies are in the ultraviolet frequency range, thus enabling the monitoring of the PV neuron-DNA, within the 10s of milliseconds. In medicine, the method can be used as an ``instantaneous-on-off anesthetic.'' Supported by Nikola Tesla Labs, Stefan University.

    Stefan, V. Alexander; IAPS Team

    The novel study of the epileptogenesis mechanisms is proposed. It is based on the pulsed-operated (amplitude modulation) multi-photon (frequency modulation) fiber-laser interaction with the brain epilepsy-topion (the epilepsy onset area), so as to prevent the excessive electrical discharge (epileptic seizure) in the brain. The repetition frequency, Ω, matches the low frequency (epileptic) phonon waves in the brain. The laser repetition frequency (5-100 pulses per second) enables the resonance-scanning of the wide range of the phonon (possible epileptic-to-be) activity in the brain. The tunable fiber laser frequencies, Δω (multi photon operation), are in the ultraviolet frequency range, thus enabling monitoring of the electrical charge imbalance (within the 10s of milliseconds), and the DNA-corruption in the epilepsy-topion, as the possible cause of the disease.

    2017-06-01

    This paper presents a numerical analysis of unconstrained melting of high temperature(>1000K) phase change material (PCM) inside a cylindrical container. Sodium chloride and Silicon carbide have been used as phase change material and shell of the capsule respectively. The control volume discretization approach has been used to solve the conservation equations of mass, momentum and energy. The enthalpy-porosity method has been used to track the solid-liquid interface of the PCM during melting process. Transient numerical simulations have been performed in order to study the influence of radius of the capsule and the Stefan number on the heat transfer rate. The simulation results show that the counter-clockwise Buoyancy driven convection over the top part of the solid PCM enhances the melting rate quite faster than the bottom part.

  4. Proposed Experimental Test of Gall's Predicted Isochromatic Black Body Displacement Law

    Science.gov (United States)

    Gall, Clarence A.

    2010-03-01

    The test of any Black Body Distribution function is how well it satisfies: Stefan-Boltzmann law ( I=σT^4) ; Wien's isothermal displacement law ( λmT=b) and the maximum isothermal emitted intensity condition ( IλmT^5) . Gall's function ( Iλ=σT^6b^2 λe^-λTb) satisfies these conditions exactly and unlike all previous candidates employs the original empirical constants ( σ,b) in its formulation. Distinct from Planck and all others, it predicts an isochromatic displacement law: λTm=6b, where Tm is the temperature of maximum emitted intensity for a given λ. The associated maximum isochromatic emitted intensity should satisfy ITmλ-5 . At wavelengths of 20, 25 and 29 μm, Tm is calculated to be 870, 696 and 600 K respectively. In this range ( Tmgoogle.com/site/purefieldphysics).

  5. A Historical View of Kirchhoff's Black Body Universal Distribution Function ( Kλ)

    2010-02-01

    Stefan (1879) established experimentally that Kirchhoff's total emitted intensity K=0^∞Kλdλ=σT^4. Boltzmann (1884) derived this result from classical thermodynamic principles. V A Michelson (1887) first defined Kλ=c1λ-6T^32e^-( c2λ^2T) . Weber suggested Kλ=c1λ-2e^[ c3T-( c2λ^2T^2) ] . Experimentally, Wien's displacement law required λmT=b. Paschen (1896) thus proposed Kλ=c1λ^-γe^- ( c2λT) with 5google.com/site/purefieldphysics), placed λT in the numerator. If temperature is defined as reciprocal wavelength then T^6λ≡λ-5. It is mathematically evident that the new location of λT is what finally allowed for the exact solution of Kirchhoff's Function with the original empirical constants ( σ,b) ! )

    2012-01-01

    Full Text Available Dimensionless experimental formulae based on a rational reciprocal function for correlation of flashpoint data of binary mixtures of two flammable components have been developed. The formulae are based on data obtained from flash-point experiments. The proposed approach requires only two coefficients, molar fraction of components and flashpoint temperatures of the pure flammable components to be known in advance. Literature data were used for formulae verification and validation obtained results indicate that accuracy is comparable and to some extent better than that of conventional flash point prediction models. Dimensional analysis and scaling of data have been performed in order to define the correct construction of the equation fitting flash-point data in dimensionless form using the independent variables suggested by Catoire. Stefan number relevant flash-point of a single compound or a blend has been defined.

  9. Steady-State Diffusion of Water through Soft-Contact LensMaterials

    Energy Technology Data Exchange (ETDEWEB)

    2005-01-31

    Water transport through soft contact lenses (SCL) is important for acceptable performance on the human eye. Chemical-potential gradient-driven diffusion rates of water through soft-contact-lens materials are measured with an evaporation-cell technique. Water is evaporated from the bottom surface of a lens membrane by impinging air at controlled flow rate and humidity. The resulting weight loss of a water reservoir covering the top surface of the contact-lens material is recorded as a function of time. New results are reported for a conventional hydrogel material (SofLens{trademark} One Day, hilafilcon A, water content at saturation W{sub 10} = 70 weight %) and a silicone hydrogel material (PureVision{trademark}, balafilcon A, W{sub 10} = 36 %), with and without surface oxygen plasma treatment. Also, previously reported data for a conventional HEMA-SCL (W{sub 10} = 38 %) hydrogel are reexamined and compared with those for SofLens{trademark} One Day and PureVision{trademark} hydrogels. Measured steady-state water fluxes are largest for SofLens{trademark} One Day, followed by PureVision{trademark} and HEMA. In some cases, the measured steady-state water fluxes increase with rising relative air humidity. This increase, due to an apparent mass-transfer resistance at the surface (trapping skinning), is associated with formation of a glassy skin at the air/membrane interface when the relative humidity is below 55-75%. Steady-state water-fluxes are interpreted through an extended Maxwell-Stefan diffusion model for a mixture of species starkly different in size. Thermodynamic nonideality is considered through Flory-Rehner polymer-solution theory. Shrinking/swelling is self-consistently modeled by conservation of the total polymer mass. Fitted Maxwell-Stefan diffusivities increase significantly with water concentration in the contact lens.

  10. Moses as a role model in the Serbia charters after 1371 changing patterns

    Directory of Open Access Journals (Sweden)

    Vujošević Žarko

    2008-01-01

    Full Text Available The aspects of the Old Testament figure of Moses highlighted in the charters of post-Nemanjić Serbia, or under the Lazarević and Branković dynasties (1371-1459, testify to a changed attitude towards Old Testament role models. While members of the Nemanjić house such as the archbishop Sava I and the rulers Stefan of Dečani and Dušan look up to Moses as a "religious leader", a prayerful intercessor before God and a victorious warrior, all of that for the sake of the "chosen" people, the role he is assigned in the arengae of the charters issued by prince Lazar and despots Stefan Lazarević and Đurađ Branković is completely different. In the universal Christian context of the post-1371 arengae Moses figures as a "prophet" and the builder of the Tabernacle - a prefiguration of the Church, thereby epitomizing a major stage in the salvation history of humankind. The role of Moses, as well as that of David, the only other Old Testament figure still referred to in the charters of the period, has a universal ecclesiologically interpreted, significance. This new pattern of interpreting Moses implies that the ruler’s main virtue now becomes his concern for the "true faith" and the houses of God. The practice of the Nemanjićs as regards selection and interpretation of Old Testament themes is reestablished by the titular despots of the Branković dynasty. In their charters, the first part of the Bible with Moses as a popular leader reassumes a "national" character and becomes part of the ideological apparatus intended to posit the Serbs as a "New Israel".

    Directory of Open Access Journals (Sweden)

    Krzysztof Kozłowski

    2010-01-01

    Full Text Available This article supports the thesis that Carl Dalhaus’s interpretation of the Wagnerian musical drama (drama is here understood as a “dramatic musical form” existing in the score, which fully comes into being only on stage as a concrete artistic creation is not totally in opposition to StefanKunze’s interpretation, according to whom the Wagnerian drama, as the whole musical theatre of Wagner, is in fact the “imaginative theatre”. It is possible to defend this thesis thanks to my conviction that “imaginativeness” of the theatre and its reality (staging are not mutually exclusive although they create a particular tension. This article consists of two parts. The first one presents Carl Dalhaus’s interpretation according to which the staging belongs to the history of a particular work of drama, forming its unique character every time again. The other part of the text discusses Stefan Kunze’s interpretation that the imaginary theatre is a part of the dramatic-musical form. There is a punch line, or a specific coda, at the end of the second part of the article, which explains the meaning of both, Dalhaus’s and Kunze’s points of view, seen also from the perspective of Wagner’s musical drama itself. My interpretation presented in this article is – referring to the current state of research and in spite of a large number of literature on this subject – new and original although the meaning of both theories is of great importance for the Wagnerian studies. My interpretation may serve to better understand both – the paradox of Wagnerian studies and the artistic work to which these theories refer.

  13. Rigorous Multicomponent Reactive Separations Modelling: Complete Consideration of Reaction-Diffusion Phenomena

    International Nuclear Information System (INIS)

    Ahmadi, A.; Meyer, M.; Rouzineau, D.; Prevost, M.; Alix, P.; Laloue, N.

    2010-01-01

    This paper gives the first step of the development of a rigorous multicomponent reactive separation model. Such a model is highly essential to further the optimization of acid gases removal plants (CO 2 capture, gas treating, etc.) in terms of size and energy consumption, since chemical solvents are conventionally used. Firstly, two main modelling approaches are presented: the equilibrium-based and the rate-based approaches. Secondly, an extended rate-based model with rigorous modelling methodology for diffusion-reaction phenomena is proposed. The film theory and the generalized Maxwell-Stefan equations are used in order to characterize multicomponent interactions. The complete chain of chemical reactions is taken into account. The reactions can be kinetically controlled or at chemical equilibrium, and they are considered for both liquid film and liquid bulk. Thirdly, the method of numerical resolution is described. Coupling the generalized Maxwell-Stefan equations with chemical equilibrium equations leads to a highly non-linear Differential-Algebraic Equations system known as DAE index 3. The set of equations is discretized with finite-differences as its integration by Gear method is complex. The resulting algebraic system is resolved by the Newton- Raphson method. Finally, the present model and the associated methods of numerical resolution are validated for the example of esterification of methanol. This archetype non-electrolytic system permits an interesting analysis of reaction impact on mass transfer, especially near the phase interface. The numerical resolution of the model by Newton-Raphson method gives good results in terms of calculation time and convergence. The simulations show that the impact of reactions at chemical equilibrium and that of kinetically controlled reactions with high kinetics on mass transfer is relatively similar. Moreover, the Fick's law is less adapted for multicomponent mixtures where some abnormalities such as counter

More than other Serbian archbishops, Nikodim revered St. Sava. He wrote about him with great love and viewed his own work as the hegoumenos of Hilandar. as an anchorite in the Karyes Cell and as the Serbian archbishop, as the continuation of Sava's deed. If, in his day. it was already believed that St. Sava was the patron of the Church of the Holy Apostles in Peć, then the fact that Nikodim erected St. Demetrios next to it should be interpreted as his desire to propagate St. Sava's ideas. However, Nikodim fulfilled this intention with the frescoes around his tomb. With the paintings of The Descent of the Holy Spirit and the first two Ecumenical Councils (Fig. 3 he expressed the idea about the beginnings of Christ's church on Earth, its establishment and its nature of communion.

Para tanto, vale-se do contraste entre as formas de mediação da informação estabelecidas no século XX (e vigentes até o início do século XXI e as novas formas de produção, circulação, mediação e acesso a informação. O principal ponto a ser destacado é a mudança de um perfil de mediação centrado na figura de editores e produtores para uma mediação a princípio lida como “tecnológica” - posto que encarnada por fórmulas matemáticas de algoritmos - mas que é concebida por engenheiros de grandes empresas como Google e Facebook, alimentada pelas informações dos próprios usuários das plataformas e utilizada tanto por empresas para finalidades econômicas quanto por governos em suas agendas políticas. Conclui-se que as mudanças na estrutura sociotécnica do “regime de informação” vigente (conforme autores como Bernd Frohmann e González de Gómez, embora permitam avanços nas mais diversas áreas (educação, saúde, segurança pública, consumo, mobilidade urbana e outros, podem trazer efeitos deletérios para a cultura e para a criatividade humana, principalmente no que se refere à privacidade e ao acesso a um conjunto diversificado de artefatos culturais, científicos e informativos.

In this study, we estimated the economic consequences of perioperative administration using FCM vs usual care in patients with IDA from the perspective of a German hospital using decision-analytic modeling.Materials and methods: The model was populated with clinical inputs (transfusion rates, blood units transfused, hospital length of stay from a previously reported randomized trial comparing FCM vs usual care for managing IDA patients undergoing elective abdominal surgery. We applied a hospital perspective to all costs, excluding surgery-related costs in both treatment arms. One-way sensitivity analyses were undertaken to evaluate key drivers of cost analysis.Results: The average costs per case treated using FCM compared to usual care were €2,461 and €3,246, respectively, for resource expenses paid by hospital per case. This would suggest potential savings achieved with preoperative intravenous iron treatment per patient of €786 per case. A sensitivity analysis varying the key input parameters indicated the cost analysis is most sensitive to changes in the length of stay and the cost of hospitalization per day.Conclusion: Perioperative administration

Data were collected via a 30-minute, face-to-face interview in six countries and via a web-based survey in the seventh country. The questionnaire evaluated the effect of six features associated with FVIII products on the choice of the product; the structure and flow of data collection was designed to eliminate potential bias.Results: Two-thirds of the respondents were using recombinant FVIII products. Only 17% were generally dissatisfied with current FVIII products, whereas >40% of the respondents were dissatisfied with frequency of administration and storage issues when traveling. The majority noted restrictions in their daily activities, particularly travel and sports. Most of them (85%, stored their product in the refrigerator and of these, 88% believed that it should always be stored there. These patients were also less satisfied with the product overall, more concerned about storage temperature, more restricted in daily activities, and spent more time on preparation and injection compared with patients who stored their product at room temperature. Conjoint analysis revealed that origin of FVIII (plasma-derived vs recombinant was the strongest driver of product choice among all respondents, followed by storage flexibility (temperature, reconstitution device, and administration frequency. In this study, we did not investigate the efficacy and safety of

    Full Text Available Bernd Kowall, Wolfgang Rathmann Institute of Biometrics and Epidemiology, German Diabetes Center, Leibniz Center for Diabetes Research at Heinrich Heine University Düsseldorf, Düsseldorf, Germany Abstract: Glycated hemoglobin (HbA1c has recently been recommended for the diagnosis of type 2 diabetes mellitus (T2DM by leading diabetes organizations and by the World Health Organization. The most important reason to define T2DM is to identify subjects with high risk of diabetes complications who may benefit from treatment. This review addresses two questions: 1 to assess from existing studies whether there is an optimal HbA1c threshold to predict diabetes complications and 2 to assess how well the recommended 6.5% cutoff of HbA1c predicts diabetes complications. HbA1c cutoffs derived from predominantly cross-sectional studies on retinopathy differ widely from 5.2%–7.8%, and among other reasons, this is due to the heterogeneity of statistical methods and differences in the definition of retinopathy. From the few studies on other microvascular complications, HbA1c thresholds could not be identified. HbA1c cutoffs make less sense for the prediction of cardiovascular events (CVEs because CVE risks depend on various strong risk factors (eg, hypertension, smoking; subjects with low HbA1c levels but high values of CVE risk factors were shown to be at higher CVE risk than subjects with high HbA1c levels and low values of CVE risk factors. However, the recommended 6.5% threshold distinguishes well between subjects with and subjects without retinopathy, and this distinction is particularly strong in severe retinopathy. Thus, in existing studies, the prevalence of any retinopathy was 2.5 to 4.5 times as high in persons with HbA1c-defined T2DM as in subjects with HbA1c <6.5%. To conclude, from existing studies, a consistent optimal HbA1c threshold for diabetes complications cannot be derived, and the recommended 6.5% threshold has mainly been brought about

In survivors, different degrees of functional complaints need to be restored or prevented (eg, post-thrombotic syndrome, pulmonary hypertension. Therefore, rehabilitation after venous thromboembolism is recommended in Germany. However, a structured rehabilitation program has not been defined for this indication. Here, we present the experience of a single rehabilitation center. Methods: Data from consecutive pulmonary embolism (PE patients who were referred for a 3-week inpatient rehabilitation program from 2006 to 2014 were retrospectively evaluated. Results: In all, 422 patients were identified. The mean age was 63.9±13.5 years, the mean body mass index (BMI was 30.6±6.2 kg/m2, and 51.9% were female. Deep vein thrombosis according to PE was known for 55.5% of all patients. We applied a wide range of therapeutic interventions such as bicycle training with monitored heart rate in 86.7%, respiratory training in 82.5%, aquatic therapy/swimming in 40.1%, and medical training therapy in 14.9% of all patients. Adverse events (AEs occurred in 57 patients during the 3-week rehabilitation period. The most common AEs were cold (n=6, diarrhea (n=5, and infection of the upper or lower respiratory tract that was treated with antibiotics (n=5.

    The Nobel Prize in Physiology or Medicine has been given in recognition of work in the neurosciences a number of times. Laureates have been awarded for work on both fundamental and more complex nervous system functions. This review is restricted to contributions by 20th century laureates to the understanding of fundamental nervous system function on the cellular level. In 1906, Camillo Golgi and Ramón y Cajal were awarded for their work on the microscopic structure of the nervous system. Their achievement and those of others within this field, coupled with technological progress, gradually allowed more complex physiological studies. In 1932, the prize was awarded to Charles Sherrington and Edgar Adrian for their discoveries of how neurons function. They were followed in 1944 by Herbert Gasser and Joseph Erlanger who uncovered the highly differentiated functions of single nerve fibers. Alan Hodgkin and Andrew Huxley were awarded for the detection of the ionic mechanism of the action potential and its mathematical explanation in 1963. In 1991, Erwin Neher and Bernd Sakmann were awarded for their work on single ion channels. Although the scientists who proved the hypothesis (Fridjof Nansen, Wilhelm His, and August Forel) were never awarded by the Nobel Committee, their studies gave rise to one of the most fundamental questions in 20th century neuroscience: How is information carried from one neuron to another or to an effector cell? This was first solved in the vegetative nervous system, and, in 1936, Henry Dale and Otto Loewi received the prize for their discoveries relating to chemical transmission of nerve impulses. In 1963, John Eccles was awarded the prize for his work on the physiology of synapses. In 1970, Bernhard Katz received the Nobel Prize for the discovery of quantal release. Katz shared the prize with Julius Axelrod and Ulf von Euler, who were central in finding that transmitters are stored in presynaptic vesicles and that the effect in many synapses is

However, little is known about the validity of home-based spirometry measurements of lung function in COPD. Therefore, as part of this study, following suitable training, patients recorded daily home-based spirometry measurements in addition to undergoing periodic in-clinic spirometric testing throughout the study duration. We subsequently determined the validity of home-based spirometry for detecting changes in lung function by comparing in-clinic and home-based forced expiratory volume in 1 second in patients who underwent stepwise fluticasone propionate withdrawal over 12 weeks versus patients remaining on fluticasone propionate for 52 weeks. Bland–Altman analysis of these data confirmed good agreement between in-clinic and home-based measurements, both across all visits and at the individual visits at study weeks 6, 12, 18, and 52. There was a measurable difference between the forced expiratory volume

Methods: A systematic literature review of randomized, controlled clinical trials in patients with COPD was performed to evaluate the efficacy and safety of olodaterol and indacaterol. Network meta-analysis and adjusted indirect comparison methods were employed to evaluate treatment efficacy, using outcomes based on trough forced expiratory volume in 1 second (FEV1, Transition Dyspnea Index, St George’s Respiratory Questionnaire total score and response, rescue medication use, and proportion of patients with exacerbations. Results: Eighteen trials were identified for meta-analysis (eight, olodaterol; ten, indacaterol. Olodaterol trials included patients of all severities, whilst indacaterol trials excluded patients with very severe COPD. Concomitant maintenance bronchodilator use was allowed in most olodaterol trials, but not in indacaterol trials. When similarly designed trials/data were analyzed for change from baseline in trough FEV1 (liters, the following mean differences (95% confidence interval were observed: trials excluding concomitant bronchodilator: indacaterol 75 mcg versus olodaterol 5 mcg, –0.005 (–0.077 to 0.067, and indacaterol 150 mcg

Annette Haberl (HIV-Department, J. W. Goethe-University Hospital, Frankfurt, Dr. med. Brigitte Schmied (Otto-Wagner Spital, Wien. In Germany during the last years about 200-250 HIV1-infected pregnant women delivered a baby each year, a number that is currently increasing. To determine the HIV-status early in pregnancy voluntary HIV-testing of all pregnant women is recommended in Germany and Austria as part of prenatal care. In those cases, where HIV1-infection was known during pregnancy, since 1995 the rate of vertical transmission of HIV1 was reduced to 1-2%. This low transmission rate has been achieved by the combination of anti-retroviral therapy of pregnant women, caesarean section scheduled before onset of labour, anti-retroviral post exposition prophylaxis in the newborn and refraining from breast-feeding by the HIV1-infected mother. To keep pace with new results in research, approval of new anti-retroviral drugs and changes in the general treatment recommendations for HIV1-infected adults, in 1998, 2001, 2003 and 2005 an interdisciplinary consensus meeting was held. Gynaecologists, infectious disease specialists, paediatricians, pharmacologists, virologists and members of the German AIDS Hilfe (NGO were participating in this conference to update the prevention strategies. A fifth update became necessary in 2008. The updating process was started in January 2008 and was terminated in September 2008. The guidelines provide new recommendations on the indication and the starting point for HIV-therapy in pregnancies without complications, drugs and drug combinations to be

The main cause can be traced back to an irregular or absent hypothalamic GnRH secretion, whereas only a minority suffers from a pituitary disorder. The choice of treatment to reverse this situation is a pulsatile GnRH application or a direct ovarian stimulation using gonadotropin injections. The goal is to achieve a proper ovarian function in these cases for a short time to allow ovulation and chance of pregnancy. Since the pulsatile GnRH treatment lost its former importance, several gonadotropins are in use to stimulate follicular growth, such as urine-derived human menopausal gonadotropin, highly purified follicle stimulating hormone (FSH or recombinant FSH, all with different success. The introduction of recombinant luteinizing hormone (LH and FSH provided an opportunity to investigate the distinct influences of LH and FSH alone and in combination on follicular growth in monofollicular ovulation induction cycles, and additionally on oocyte maturation, fertilization competence of the oocyte and embryo quality in downregulated IVF patients. Whereas FSH was known to be indispensable for normal follicular growth, the role of LH remained questionable. Downregulated IVF patients with this short-term gonadotropin depletion displayed no advance in stimulation success with the use of recombinant LH. Patients with hypogonadotropic hypogonadism undergoing monofollicular stimulation for ovulation induction showed clearly a specific role and need for both hormones in normal follicular growth. Therefore, a

    Full Text Available The article sheds light on some unfamiliar details related to Penal Code Draft for Serbia from 1839, authored by the mayor of Zemun Vasilije Lazarević. As this document to a large extent remained neglected in monographs and articles in relation with codification of criminal law in Serbia in 19th century, the author resolved to explore this topic thoroughly. Archival materials provided solid basis to learn more information in terms of what occurred to forgotten draft after Ministry of Justice had received it. Lazarević consigned his draft to Ministry of Justice between the end of July and beginning of October 1839. Not long afterwards, the Ministry proposed State Council to form a committee tasked with revision of the draft. State Council rejected the proposal, instructing the Ministry to appoint persons to revise the draft on its own. Only when they have finished revision, the draft would be examined by the State Council's committee. In the following year, 1840, Ministry of Justice requested Prince Mihailo Obrenović (1839-1842, 1860-1868 to elect members of the committee to revise Lazarević's draft. Not having jurisdiction over fullfillment of such request, the prince recommended State Council to do so. State Council opted for Minister of Justice Stefan Stefanović-Tenka, legislator Jovan Hadžić, judge of Appellate Court Lazar Zuban and head of Depatment of Police and Economics in Ministry of Internal affairs Stefan Radičević. However, due to turbulent political climate in Serbia, the committee was unable to execute its duty. In 1841, a new comittee was formed by State Council. It was made up of member of State Council Golub Petrović, Minister of Justice Stefan Radičević, head of Department of Quarantine and Sanitation in Ministry of Internal Affairs Jovan Stejić and professor of law Jovan Raić. Existing historical sources and literature reveal contradictory data regarding the committee's activity. The last commission was appointed

    Nuclear Training Centre Ljubljana was established in 1989 and a few years later its activity expanded from pure professional training to public information, as well. The goal was to achieve better social acceptance of nuclear power in Slovenia which was very low in early 1990's. We focused on schoolchildren and other organized groups and since then we had more than 120,000 visitors. The mainstays of our activity are a live lecture and a permanent exhibition. In the recent years the Nuclear Information Centre and its web site www.icjt.org has also become a respected source of information for the media and the general public. In the first few years it was quite hard to notice any improvement in public attitude and even later, when nuclear power became less controversial, it was difficult to link this change to the activities of the Nuclear Information Centre. Recently, however, several independent polls on a representative sample of general population proved that in a long term, our activities did have tangible results and that Nuclear Information Centre as part of Jozef Stefan Institute is regarded as trusted source of information. An Eurobarometer poll showed that Slovenia ranked among the first three countries in Europe regarding knowledge of nuclear waste issues in Europe. Another poll showed that Jozef Stefan Institute is the most trusted institution on radioactive waste issues. A third independent poll showed that the knowledge and the attitude towards nuclear is most favorable in the youngest age group of general population, i.e., many of whom have previously visited the Nuclear Information Centre. These are all indications that the activities of the Nuclear Information Centre have contributed to a measurable change in the public opinion and knowledge of nuclear issues in Slovenia. Furthermore this shows that informing youngsters is a very long term activity and that first tangible results can only be expected in 15 years or so. On the other hand, however

    Glacier surfaces exhibit an amazing variety of meltwater-induced morphologies, ranging from small scale ripples and dunes on the bed of supraglacial channels to meandering patterns, till to large scale drainage networks. Even though the structure and geometry of these morphologies play a key role in the glacier melting processes, the physical-based modeling of such spatial patterns have attracted less attention than englacial and subglacial channels. In order to partially fill this gap, our work concerns the large scale channelization occurring on the ice slopes and focuses on the role of turbulence on the wavelength selection processes during the channelization inception. In a recent study[1], two of us showed that the morphological instability induced by a laminar film flowing over an ice bed is characterized by transversal length scales of order of centimeters. Being these scales much smaller than the spacing observed in the channelization of supraglacial drainage networks (that are of order of meters) and considering that the water films flowing on glaciers can exhibit Reynolds numbers larger than 104, we investigated the role of turbulence in the inception of channelization. The flow-field is modeled by means of two-dimensional shallow water equations, where Reynolds stresses are also considered. In the depth-averaged heat balance equation an incoming heat flux from air is assumed and forced convection heat exchange with the wall is taken into account, in addition to convection and diffusion in the liquid. The temperature profile in the ice is finally coupled to the liquid through Stefan equation. We then perform a linear stability analysis and, under the assumption of small Stefan number, we solve the differential eigenvalue problem analytically. As main outcome of such an analysis, the morphological instability of the ice-water interface is detected and investigated in a wide range of the independent parameters: longitudinal and transversal wavenumbers

  12. A Generic Model for Prediction of Separation Performance of Olefin/Paraffin Mixture by Glassy Polymer Membranes

    Full Text Available The separation of olefin/paraffin mixtures is an important process in petrochemical industries, which is traditionally performed by low temperature distillation with a high-energy consumption, or complex extractive distillationand adsorption techniques. Membrane separation process is emerging as an alternative for traditional separation processes with respect to low energy and simple operation. Investigations made by various researchers on polymeric membranes it is found that special glassy polymers render them as suitable materials for olefin/paraffin mixture separation. In this regard, having some knowledge on the possible transport mechanism of these processes would play a significant role in their design and applications. In this study, separation behavior of olefin/paraffin mixtures through glassy polymers was modeled by three different approaches: the so-called dual transport model, the basic adsorption-diffusion theory and the general Maxwell-Stefan formulation. The systems chosen to validate the developed transport models are separation of ethane-ethylene mixture by 6FDA-6FpDA polyimide membrane and propane-propylene mixture by 6FDA-TrMPD polyimide membrane for which the individual sorption and permeation data are available in the literature. Acritical examination of dual transport model shows that this model fails clearly to predict even the proper trend for selectivities. The adjustment of pemeabilities by accounting for the contribution of non-selective bulk flow in the transport model introduced no improvement in the predictability of the model. The modeling results based on the basic adsorption-diffusion theory revealed that in this approach only using mixed permeability data, an acceptable result is attainable which fades out the advantages of predictibility of multicomponent separation performance from pure component data.

    The UCLA work on this grant was to design and help implement an object-oriented version of the GTC code, which is written in Fortran90. The GTC code is the main global gyrokinetic code used in this project, and over the years multiple, incompatible versions have evolved. The reason for this effort is to allow multiple authors to work together on GTC and to simplify future enhancements to GTC. The effort was designed to proceed incrementally. Initially, an upper layer of classes (derived types and methods) was implemented which called the original GTC code 'under the hood.' The derived types pointed to data in the original GTC code, and the methods called the original GTC subroutines. The original GTC code was modified only very slightly. This allowed one to define (and refine) a set of classes which described the important features of the GTC code in a new, more abstract way, with a minimum of implementation. Furthermore, classes could be added one at a time, and at the end of the each day, the code continued to work correctly. This work was done in close collaboration with Y. Nishimura from UC Irvine and Stefan Ethier from PPPL. Ten classes were ultimately defined and implemented: gyrokinetic and drift kinetic particles, scalar and vector fields, a mesh, jacobian, FLR, equilibrium, interpolation, and particles species descriptors. In the second state of this development, some of the scaffolding was removed. The constructors in the class objects now allocated the data and the array data in the original GTC code was removed. This isolated the components and now allowed multiple instantiations of the objects to be created, in particular, multiple ion species. Again, the work was done incrementally, one class at a time, so that the code was always working properly. This work was done in close collaboration with Y. Nishimura and W. Zhang from UC Irvine and Stefan Ethier from PPPL. The third stage of this work was to integrate the capabilities of the various versions of

    shapes such as ellipsoids, mushrooms, spherulites and discs. The final morphology of the wax particles is governed by the interfacial, inertial, viscous and thermal effects, which can be studied over a range of Weber, Capillary, Reynolds and Stefan numbers. A simplified Stefan problem for a spherical drop was solved. The time required to initiate a phase transition at the interface of the molten wax and water after impact was estimated and correlated with the drop deformation history and final wax particle shape to develop a capability to predict the shape. While the microfluidic synthesis approach offers precise control over morphology and functionality, large particle throughput is a limitation. The drop impact in a liquid medium emulsion approach is limited to crosslinking or heat sensitive materials but can be extended to large scale production for industrial applications. Both approaches are simple, robust and cost effective making them viable and attractive solutions for complex particle synthesis. The choice of the approach is dependent on considerations such as particle material, size, shape, throughput and end application.

    . In this thesis, both of them are discussed respectively. Additionally, the diffusion phenomena of landfill gas mixtures can be expressed by Maxwell-Stefan equations and Fick's law. According to the relation between Maxwell-Stefan equations and Fick's law, the diffusion coefficients of landfill gas mixtures can be estimated in theory. The major part of this model is based on the theory of mass transfer through porous media. In which, mass balance, momentum balance and constitutive relations among multi-phase are employed for modeling. Landfill gas adsorption processes in two-dimension porous media can be thus simulated with application of this model. (orig.)

    Full Text Available The results of a more careful examination of the painting in Raška from the period of the king and later, of the emperor, Stefan Dušan (1331-1355 render untenable the earlier assessments about its strikingly provincial character and negligible artistic value. The fragmentarily preserved painting of the exonarthex in Djurdjevi stupovi, in Budimlja (spring 1343 - autumn 1345, and St. Nikola in Palež near Studenica (probably the fifth decade of the 14th century, undoubtedly indicate a highly progressive style and very high artistic value. According to their pictorial features, these two monuments are no less sophisticated than the most advanced fresco ensembles of Dušan's times in Macedonia. Besides that, in the painting of the Budimlja exonarthex and the church in Palež, one can also perceive certain iconographic and programmatic novelties, which are characteristic of churches from that period in the south eastern parts of the Serbian state (the Menologion, the elevation of the rulers' portraits to the second zone of the fresco paintings, etc. The coordination of the iconography and the programme with the principles of the Palaiologan high renaissance can also be observed in the fresco painting of some other monuments of Raška from the reign of Stefan Dušan. We refer to the Church of the Annunciation in Dobrun, the exonarthex in Sopoćani, the Chuch of St. Nicholas in Baljevac, the so-called Latin Church in Prokuplje, and St. Nicholas in Usee. In the majority of the said monuments, one can notice traces of the rather lively cultural relations with the central and southern parts of the expanded Serbian state. Nevertheless, the painting in the enumerated churches has been only fragmentarily preserved. Consequently, considerations about the fresco painting of the Bela Crkva Karanska (the White Church of Karan as a rather well preserved monumental ensemble, acquires particular significance for art research in the north western part of Du

    Full Text Available In melting and assimilation of a cylindrical shaped additive in an agitated hot melt bath during the process of preparation of cast iron and steel of different grades, an unavoidable step of transient conjugated conduction-controlled axisymmetric freezing and melting of the bath material onto the additive immediately after its dunking in bath occurs. Decreasing the time of completion of this step is of great significance for production cost reduction and increasing the productivity of such preparations. Its suitable mathematical model of lump-integral type is developed. Its nondimensional format indicates the dependence of this step upon independent nondimensional parameters- the bath temperature, θb the modified Biot number, Bim denoting the bath agitation, the property-ratio, B and the heat capacity-ratio, Cr of the melt bath-additive system, the Stefan number, St pertaining to the phase-change of the bath material. The model provides the closed-form expressions for both the growth of the frozen layer thickness, ξ onto the additive and the heat penetration depth, η in the additive. Both are functions of these parameters, but when they are transformed to the growth of the frozen layer thickness with respect to the heat capacity ratio per unit Stefan number; and the time per unit property-ratio, B, their expressions become only a function of single parameter, the conduction factor, Cof consisting of the parameters, B, Bim and θb. The closed-form expression for the growth of the maximum thickness of the frozen layer, its time of growth, the time of the freezing and melting; the heat penetration depth are also derived. When the heat penetration depth approaches the central axis of the cylindrical additive in case of the complete melting of the frozen layer developed Cof≤11/72. It is found that the decreasing Cof reduces both the time of this unavoidable step and the growth of the maximum frozen layer thickness and at Cof=0, the frozen layer

    Full Text Available Dans la Chronique du roi David (1991 , Stefan Heym (1913-2001 propose une perspective favorable sur le potin, nonobstant la censure biblique de cette activité (ex : Proverbe 11:13. La réécriture satirique de Heym de l'histoire biblique se concentre sur le personnage d’Ethan, un écrivain-historien nommé par le roi Salomon pour composer un rapport officiel sur la vie et l’arrivée au pouvoir du roi David. À un moment donné les deux fils d’Ethan, Sem et Sheleph, reviennent du marché et racontent à Ethan certaines rumeurs «savoureuses» qu'ils y ont entendues. Ces rumeurs, tandis qu’elles sont un peu exagérées et embellies, fournissent toutefois des aperçus de la situation politique qui sont beaucoup plus fidèles à la vérité que les inventions des porte-parole officiels. Pour justifier le portrait littéraire de Heym du potin comme une voie pour communiquer la vérité subversive dans les régimes autoritaires, je cite la recherche historique systématique de Robert Darnton au sujet des voies diverses pour communiquer les nouvelles de Paris au dix-huitième siècle (Darnton, 2000. In The King David Report (1972, Stefan Heym (1913-2001 offers a favorable view of gossip, notwithstanding biblical censuring of that activity (e.g. Proverb 11:13. Heym's satirical re-telling of the biblical story focuses on the character of Ethan, a writer-historian appointed by King Solomon to compose an official report on the life and rise to power of King David. At one point Ethan's two sons, Shem and Sheleph, come back from the market, telling Ethan of some "juicy" rumors they heard there. These rumors, while using some exaggerations and added embellishments, nevertheless provide insights into the political situation much more faithful to the truth than the fabrications of official spokespersons. To substantiate Heym's literary portrayal of gossip as a channel for communicating subversive truth in authoritarian regimes, I cite Robert Darnton
