Subjects: Conservation science

description: Desalination by poulticing, i.e. extraction of soluble salts through the application of a moistened absorbing material on the surface of the object/masonry to be treated, often leads to questionable results although the method is very commonly used in architectural conservation. In the following paper a review of the various poultice desalination techniques is presented in order to determine where the gaps of knowledge occur and what further studies and experiments are needed to improve our knowledge in that field.
Entsalzen mit Hilfe von Kompressen, das heißt das Auslaugen von in Wasser löslichen Salzen durch Anbringen von durchfeuchtetem absorbierendem Material an der Oberfläche eines zu behandelnden Objektes, wie zum Beispiel Mauerwerk, führt häufig zu fragwürdigen Ergebnissen, obwohl diese Methode oft beim Bauinstandsetzen verwendet wird. In diesem Beitrag wird ein Überblick über die unterschiedlichen technischen Varianten der Kompressenentsalzung geboten. Dabei wird gezeigt, wo es noch Wissenslücken gibt und welche Untersuchungen und Versuche notwendig sind, um unsere Kenntnisse auf diesem Gebiet zu vertiefen.

description: After picking out what may seem more realistic minimal gravitational deformation of quantum mechanics, we study its back reaction on gravity. The large distance behaviour of Newtonian potential coincides with the result obtained by using of effective field theory approach to general relativity (the correction proves to be of repulsive nature). The short distance corrections result in Planck mass black hole remnants with zero temperature. The deformation of position-momentum uncertainty relations leads to the superluminal motion that can be avoided by making similar deformation of time-energy uncertainty relation. Such deformation also avoids UV divergences in QFT.

description: We introduce a stochastic model of binary opinion dynamics in one dimension. The binary opinions $\pm 1$ are analogous to up and down Ising spins and in the equivalent spin system, only the spins at the domain boundary can flip. The probability that a spin at the boundary is up is taken as $P_{up} = \frac {s_{up}} {s_{up} + δs_{down}}$ where $s_{up} (s_{down})$ denotes the size of the domain with up (down) spins neighbouring it. With $x$ fraction of up spins initially, a phase transition is observed in terms of the exit probability and the phase boundary is obtained in the $δ-x$ plane. In addition, we investigate the coarsening behaviour starting from a completely random state; conventional scaling is observed only at the phase transition point $δ= 1$. The scaling behaviour is compared to other dynamical phenomena; the model apparently belongs to a new dynamical universility class as far as persistence is concerned although the dynamical exponent, equal to one, is identical to a similar model with no stochasticity.

Contemporary kunqu composition
Creators: name: Jones, Juliane
Publisher: name: University of British Columbia
Year: 2014

description: Kunqu is an operatic singing style that developed in the town of Kunshan near Suzhou, China in the sixteenth century. Kunqu is currently experiencing a revival in China, but only five professional musicians are actively composing, continuing the tradition of creating kunqu melodies with qupai (preexisting tune structures) for the singing of literary lyrics. This dissertation investigates current practices of kunqu composition with an ethnographic approach that employs a variety of research techniques including: translations of historical and contemporary compositional treatises, participant-observation in composition lessons, formal and informal interviews, as well as analysis of musical scores, sound recordings, and live performances. I theorize kunqu composition as a process of composers’ translating personal and intellectual knowledge of historical Chinese and Western music as well as collective knowledge of the key branches of kunqu theory into performable and audible musical works (introduction). To explain the genre’s musical vocabulary, I describe traditional and contemporary features such as: relationships between linguistic and musical tones, musical modes, qupai, rhythm and meter schemes, and use of musical instruments. I then describe the process of composing an aria from qupai according to contemporary practice (chapter 2). To contextualize kunqu composition, I trace the history of the genre (chapter 3). Then I analyze how two contemporary kunqu composers engage in methods of kunqu composition in their own creative and theoretical ways (chapters 4 and 5). Finally, I explore a musical dialogue between Western and Chinese musical cultures through examining Tan Dun’s version of the kun opera The Peony Pavilion performed at the Metropolitan Museum in 2012 (chapter 6).
Application of a salutogenic design model to the architecture of low-income housing
Creators: name: Ziegler, Ellen
Publisher: name: University of British Columbia
Year: 2014

description: A strong correlation exists between inadequate housing and stress, and between stress and health. Studies have found that inadequate housing places both mental and physical stress on residents and that families and individuals living in low-income housing are often facing more stress and suffer from ill health more than those living in market housing. Salutogenesis, a concept developed by Aaron Antonovsky, focuses on what causes health rather than what causes illness. He links health with the ability to comprehend, manage and apply meaning to stress. This ability is called a Sense of Coherence. The higher the sense of coherence, the less negative the impact of stress will have on mental and physical health. It has also been shown that residents in low-income housing are often confronted with multiple social, physical, emotional and financial stressors, which can further weaken their sense of coherence. In this regard, low-income residents share a similarity with the hospital patients documented in many studies of salutogenics in healthcare, in that they face an abnormally high amount of stress and may be in situations that have weakened their sense of coherence. In the 1990s architect Alan Dilani suggested that Antonovsky’s salutogenic principles be applied to the architectural design of healthcare facilities as a means to promote health. More recently, this design model has also been applied to long-term care facilities and workplaces, however it has not yet been applied to low-income housing. Although the presence of stress is not solely due to architecture, architecture and design can either intensify or mitigate the effects of stress on health. Countless studies show a relationship between the design of our built environment and health. For example, there is a direct link between access to natural light and blood pressure, between over-crowding or chronic noise and psychological stress and between healing and nature. With over 8% of the Canadian population living in low-income housing and 3.3 million households paying more than what is considered affordable on rent (>30% of their income), addressing the health impact of low-income housing design is critical.

description: Wir beschreiben die klinischen und zytogenetischen Auffälligkeiten bei einem 38-jährigen Patienten mit interstitieller Deletion 4q25-q31.1 und Verdacht auf Rieger-Syndrom. Die klinischen Auffälligkeiten umfassen Kleinwuchs, mentale Retardierung, eine membranöse Aortenstenose und subaortalen Ventrikelseptumdefekt, sowie kraniofaziale Auffälligkeiten einschließlich Mikrognathie, Zahnfehlstellungen, einer hervorstehenden Unterlippe, einer großen Nase, antimongoloider Lidachse und hypoplastischer Ohren. Eine milde Irishypoplasie und Strabismus concomitans convergens konnten zusätzlich diagnostiziert werden. Die Deletionsanalyse und Kartierung der Bruchpunkte erfolgte durch Fluoreszenz-in-Situ-Hybridisierung (FISH) von insgesamt 19 BAC-Klonen an Metaphasechromosomen des Patienten. Des Weiteren erfolgte der Versuch einer molekularen Eingrenzung des proximalen Bruchpunktes in 4q25 mittels Mikrosatellitenanalyse. Der Phänotyp des Patienten basiert nicht auf einer Deletion des Rieger-Syndrom assoziierten Gens PITX2. Phänotypische Überschneidungen mit dem Rieger-Syndrom lassen sich jedoch eventuell durch Positionseffekte erklären. Deletionen der Banden 4q25-q31.1 gehen gehäuft mit Fehlbildungen der Hände und Füße, mentaler Retardierung und Kleinwuchs einher. Des Weiteren scheinen Deletionen der Banden 4q25-q27 gehäuft mit Herzfehlbildungen assoziiert zu sein. Eine Aussage über denkbare Kandidatengene in dieser Region ist anhand der bisherigen Datenlage nicht möglich.
description: We describe the clinical and molecular findings in a 38-year-old patient carrying a de novo interstitial deletion 4q25-31.1. The clinical findings consist of small stature, mental retardation, membranous aortic stenosis and subaortal ventricular septal defect. Furthermore, craniofacial and skeletal anomalies including micrognathia with dental crowding, a prominent lower lip, a big nose, antimongoloid slant of the palpebral fissures and malformation of hands and feet could be seen. Mild iris hypoplasia and strabismus concomitant convergent were also present. Using peripheral lymphocytes, the patient’s chromosomes were cytogenetically characterized by Gbanding and further fluorescent in situ hybridization (FISH) and microsatellite analysis have been performed to narrow the breakpoints of the deletion of the aberrant chromosome 4. The phenotypic expression noted in patients with deletions of chromosome 4q25-31.1 seems to be highly variable. This report could therefore contribute to delineate phenotypes and specific malformations by comparison to cases previously described in the literature. Possible reasons for phenotypical overlap with Rieger-Syndrome are discussed.
Antithetic multilevel Monte Carlo estimation for multi-dimensional SDEs without Lévy area simulation

description: In this paper we introduce a new multilevel Monte Carlo (MLMC) estimator for multi-dimensional SDEs driven by Brownian motions. Giles has previously shown that if we combine a numerical approximation with strong order of convergence $O(Δt)$ with MLMC we can reduce the computational complexity to estimate expected values of functionals of SDE solutions with a root-mean-square error of $ε$ from $O(ε^{-3})$ to $O(ε^{-2})$. However, in general, to obtain a rate of strong convergence higher than $O(Δt^{1/2})$ requires simulation, or approximation, of Lévy areas. In this paper, through the construction of a suitable antithetic multilevel correction estimator, we are able to avoid the simulation of Lévy areas and still achieve an $O(Δt^2)$ multilevel correction variance for smooth payoffs, and almost an $O(Δt^{3/2})$ variance for piecewise smooth payoffs, even though there is only $O(Δt^{1/2})$ strong convergence. This results in an $O(ε^{-2})$ complexity for estimating the value of European and Asian put and call options.

description: We investigate the fine structure in the energy spectrum of bilayer graphene in the presence of various stacking defaults, such as a translational or rotational mismatch. This fine structure consists of four Dirac points that move away from their original positions as a consequence of the mismatch and eventually merge in various manners. The different types of merging are described in terms of topological invariants (winding numbers) that determine the Landau-level spectrum in the presence of a magnetic field as well as the degeneracy of the levels. The Landau-level spectrum is, within a wide parameter range, well described by a semiclassical treatment that makes use of topological winding numbers. However, the latter need to be redefined at zero energy in the high-magnetic-field limit as well as in the vicinity of saddle points in the zero-field dispersion relation.

Salts in Porous Materials: Thermodynamics of Phase Transitions, Modeling and Preventive Conservation
Creators: name: Steiger, Michael

Year: 2005
Subjects: Conservation science

description: The thermodynamics of phase equilibria of salts in porous materials is discussed including all relevant phase
transition reactions such as crystallization–dissolution, hydration–dehydration, and the freeze–thaw equilibrium
of water. The treatment of binary systems, i.e. only one salt and water, yields binary phase diagrams
that provide all information required for preventive conservation by environmental control. In the case of salt
mixtures, a model approach is more appropriate to predict phase equilibria and safe ranges of environmental
conditions. The properties of thermodynamic models are reviewed and several examples for the crystallization
behaviour of mixed salt systems are provided. Finally, possible applications of thermodynamic models
and their potential limits are discussed.
Die Thermodynamik der relevanten Phasenübergänge von Salzen in porösen Materialien wird vorgestellt.
Betrachtet werden Kristallisation und Lösung sowie Hydratation und Dehydratation von Salzen sowie das
Gleichgewicht zwischen flüssigem Wasser und Eis. Die Behandlung binärer Systeme, also Mischungen von
nur einem Salz mit Wasser, führen zu einfachen Phasendiagrammen, die zur Vorhersage geeigneter klimatischer
Bedingungen für die passive Konservierung herangezogen werden können. Bei Vorliegen von Salzgemischen
ist es erforderlich, thermodynamische Modelle zur Berechnung von Phasengleichgewichten und die
Vorhersage des Kristallisationsverhaltens zu verwenden. Die Eigenschaften solcher Modelle werden kurz
vorgestellt und zur beispielhaften Berechnung des Kristallisationsverhaltens einiger gemischter Salzsysteme
verwendet. Schließlich werden die Anwendungsmöglichkeiten und Grenzen thermodynamischer Modelle diskutiert.

Extrapolating from the SU(2) generalized quivers, which have a Lagrangian description, we conjecture explicit formulae for all A-type quivers of class S, which in general do not have one. We test our proposals against several expected dualities. The index can always be interpreted as a correlator in a two-dimensional topological theory, which we identify in each limit as a certain deformation of two-dimensional Yang-Mills theory. The structure constants of the topological algebra are diagonal in the basis of Macdonald polynomials of the holonomies.

description: Aus Fruchtkörpern von Hygrophorus latitabundus, H. olivaceoalbus, H. persoonii und H. pustulatus konnten zwanzig neue Cyclopentenon-Derivate (Hygrophorone) isoliert und deren Struktur mit Methoden der Kernresonanzspektroskopie (NMR) und der Massenspektrometrie (MS) aufgeklärt werden. Die relative Konfiguration der Substituenten des Cyclopentenonringes wurden durch Messung des Nuclear Overhauser Effekts (NOE), durch Vergleich von Kopplungskonstanten sowie durch Umsetzung zum cyclischen Methylboronat bestimmt. Erste Aktivitätsstudien zeigen, dass die Hygrophorone antifungisch und antibakteriell wirksam sind. Die antibakterielle Wirkung ist gegen Gram-positive Bakterien stärker als gegen Gram-negative Bakterien. Die Hygrophorone sind selbst gegen Methicillin, Ciprofloxacin und Vancomycin resistenten Bakterienstämmen hoch aktiv. Das Fragmentierungsverhalten der Hygrophorone nach Elektrospray-Ionisierung wurde untersucht. Obwohl die Substituentenfragmentierung (Abspaltung von Wasser, Essigsäure, Keten) die dominierende Fragmentierung ist, gibt es einige Schlüsselfragmente, welche die Einteilung der Hygrophorone in zwei Typen erlaubt: Typ I-Hygrophorone haben eine Hydroxy- oder Acetoxy-Gruppe an C-6, während Typ II-Hygrophorone an C-6 zum Keton oxidiert sind. Eine sehr interessante und ungewöhnliche Fragmentierung ist die Abspaltung von CO2 nach negativer Ionisierung vom Pseudomolekülion [M-H]-, welche nur durch vorgelagerte Umlagerung eines Sauerstoffes einer Hydroxygruppe stattfinden kann.
description: Twenty new cyclopentenone derivatives (hygrophorones) were isolated from fruitbodies of Hygrophorus latitabundus, H. olivaceoalbus, H. persoonii, and H. pustulatus. Their structure was elucidated by NMR and MS. The relative configuration of the substituents of the cyclopentenone ring was assigned based on nuclear overhauser effects (NOE), comparison of coupling constants, and formation of cyclic methylboronates. First activity studies showed that hygrophorones have significant antibacterial and antifungal potential. The antibacterial effect against Gram positive bacteria is stronger than against Gram negative bacteria. The hygrophorones are even active against vancomycin, methicillin and ciprofloxacin resistant bacteria. The mass spectral behaviour of hygrophorones after electrospray ionisation was investigated. Although the substituent fragmentations (loss of water, ketene, acetic acid) are the most dominating processes, there are some key ions allowing an assignment into two types: type I hygrophorones have a hydroxy- or an acetoxygroup at C-6, while type II hygrophorones are oxidized at C-6 to a ketone. An interesting and unusual fragmentation is the loss of CO2 from the [M-H]- ion which is only possible by a rearrangement including an oxygen of a hydroxyl function.

description: The coupling of a composite Higgs to the standard model fields can deviate substantially from the standard model values. In this case perturbative unitarity might break down before the scale of compositeness is reached, which would suggest that additional composites should lie well below this scale. In this paper we account for the presence of an additional spin 1 custodial triplet of rhos. We examine the implications of requiring perturbative unitarity up to the compositeness scale and find that one has to be close to saturating certain unitarity sum rules involving the Higgs and the rho couplings. Given these restrictions on the parameter space we investigate the main phenomenological consequences of the spin 1 triplet. We find that they can substantially enhance the Higgs di-photon rate at the LHC even with a reduced Higgs coupling to gauge bosons. The main existing LHC bounds arise from di-boson searches, especially in the experimentally clean channel where the charged rhos decay to a W-boson and a Z, which then decay leptonically. We find that a large range of interesting parameter space with 700 GeV < m(rho) < 2 TeV is currently experimentally viable.

description: Repair mortars mainly used in the restoration of porous limestone and sandstone were studied  under laboratory conditions for salt durability. Cubic specimens of various types of repair  mortars were exposed to sodium-sulphate solution by applying standard salt crystallization test  methods. Loss of weight and changes of mechanical properties were detected. The response of  repair mortar and porous limestone to typical wetting–drying experiments and salt exposure  experiments were compared. Uniaxial compressive strength was measured after 14, 28 days of  casting, while durability was assessed by comparing strength test results of samples kept dry  conditions, in water or after salt exposition. The results show that damaging of limestones and  repair mortars are closely related to material properties and especially to the pore-size  distribution of samples.

description: Conic linear programs, among them semidefinite programs, often behave pathologically: the optimal values of the primal and dual programs may differ, and may not be attained. We present a novel analysis of these pathological behaviors. We call a conic linear system $Ax <= b$ {\em badly behaved} if the value of $\sup { < c, x > | A x <= b }$ is finite but the dual program has no solution with the same value for {\em some} $c.$ We describe simple and intuitive geometric characterizations of badly behaved conic linear systems. Our main motivation is the striking similarity of badly behaved semidefinite systems in the literature; we characterize such systems by certain {\em excluded matrices}, which are easy to spot in all published examples. We show how to transform semidefinite systems into a canonical form, which allows us to easily verify whether they are badly behaved. We prove several other structural results about badly behaved semidefinite systems; for example, we show that they are in $NP \cap co-NP$ in the real number model of computing. As a byproduct, we prove that all linear maps that act on symmetric matrices can be brought into a canonical form; this canonical form allows us to easily check whether the image of the semidefinite cone under the given linear map is closed.

We prove that the category of hom-Lie 2-algebras and the category of 2-term $HL_\infty$-algebras are equivalent. We give a detailed study on skeletal hom-Lie 2-algebras. In particular, we construct the hom-analogues of the string Lie 2-algebras associated to any semisimple involutive hom-Lie algebras. We also proved that there is a one-to-one correspondence between strict hom-Lie 2-algebras and crossed modules of hom-Lie algebras. We give the construction of strict hom-Lie 2-algebras from hom-left-symmetric algebras and symplectic hom-Lie algebras.

A slow roll scalar field solution with power law potential is presented in the neighborhood of transition time, i.e. when the universe enters inflation phase from super-inflation. The compatibility of the model with Planck 2013 data is discussed. The domain of validity of second and the generalized second laws of thermodynamics for this solution and some other examples is studied.

description: Stream temperature dynamics during winter are less well studied than summer thermal regimes, but the winter season thermal regime can be critical for fish growth and development. The winter thermal regimes of Pacific Northwest headwater streams, which provide vital winter habitat for salmonids and their food sources, may be particularly sensitive to changes in climate because they can remain ice-free throughout the year and are often located in rain-on-snow zones. This study examined winter stream temperature patterns and controls in small headwater catchments within the rain-on-snow zone at the Malcolm Knapp Research Forest, near Vancouver, British Columbia, Canada. A diagnostic energy budget analysis highlighted that advective fluxes associated with hillslope throughflow inputs were a dominant control on the winter stream thermal regime. In addition, stream temperatures during rain-on-snow events were generally lower than during rain-on-ground events after controlling for air temperature. Methods for estimating throughflow temperatures embedded in stream temperature models were evaluated against field observations, and were found either not to account for the role of snow or to under- or over-predict throughflow temperatures by up to 5 °C. Therefore, a conceptual-parametric hillslope throughflow temperature model that coupled hydrologic and thermal processes, and accounted for the role of snow was developed and evaluated against field observations of throughflow temperatures. The hillslope throughflow temperature model was linked to stream energy exchange processes in order to predict stream temperature. The stream temperature model accurately predicted streamflow and winter stream temperature at three study catchments. The model also simulated lower throughflow temperatures during rain-on-snow versus rain-on-ground events, although the magnitude of cooling was less than suggested by empirical results. A key implication of this research is that climatic warming may generate higher winter stream temperatures in the rain-on-snow zone due to both increased temperature of throughflow inputs and reduced cooling effect of snow cover.

description: The motion of test particles in stationary axisymmetric gravitational fields is generally nonintegrable unless a nontrivial constant of motion, in addition to energy and angular momentum along the symmetry axis, exists. The Carter constant in Kerr-de Sitter spacetime is the only example known to date. Proposed astrophysical tests of the black-hole no-hair theorem have often involved integrable gravitational fields more general than the Kerr family, but the existence of such fields has been a matter of debate. To elucidate this problem, we treat its Newtonian analogue by systematically searching for nontrivial constants of motion polynomial in the momenta and obtain two theorems. First, solving a set of quadratic integrability conditions, we establish the existence and uniqueness of the family of stationary axisymmetric potentials admitting a quadratic constant. As in Kerr-de Sitter spacetime, the mass moments of this class satisfy a "no-hair" recursion relation $M_{2l+2}=a^2 M_{2l}$, and the constant is Noether-related to a second-order Killing-Stäckel tensor. Second, solving a new set of quartic integrability conditions, we establish nonexistence of quartic constants. Remarkably, a subset of these conditions is satisfied when the mass moments obey a generalized "no-hair" recursion relation $M_{2l+4}=(a^2+b^2)M_{2l+2}-a^2b^2 M_{2l}$. The full set of quartic integrability conditions, however, cannot be satisfied nontrivially by any stationary axisymmetric vacuum potential.

description: Intelligence activities in Sweden during the war were largely influenced by the same set of factors as in other neutral countries. Due to relative accessibility and limited surveillance, Sweden was a useful base for intelligence activities by foreign intelligence services, although the Swedish attitude varied over time towards the warring parties. Even before the war, Swedish authorities were suspicious of Russia, and of Russian intentions toward Sweden and Scandinavia. Contrary to these expectations, Sweden seems to have played only a marginal role for Russian intelligence during the war. The attitude towards Germany was the opposite, with a secret cooperation between the Swedish and German intelligence services, based on the perception of a common opponent in Russia. For Germany, Sweden was also an important target for war propaganda aiming to strengthen the pro-German sentiments in the Swedish press and public opinion.

description: Die polarisationsmikroskopischen Bestimmungsmethoden der durchsichtigen amorphen und kristallinen Phasen (Gläser, Minerale, synthetische Substanzen) und die hierfür notwendigen kristalloptischen Zusammenhänge sind in zahlreichen deutsch-und englischsprachigen Lehrbüchern ausführlich behandelt (siehe Literaturauswahl). Die folgende Einführung in die Mineralbestimmung im Dünnschliff kann daher auf eine breite Darstellung des Stoffes verzichten. Für die praktische Arbeit am Polarisationsmikroskop genügt es, die erforderlichenSachverhalte in einer prägnanten und auch dem mineralogisch wenig vorgebildeten Mikroskopierenden verständlichen Anleitung zusammenzufassen. Kristalloptische und kristallographische Grundlagen werden nur soweit behandelt, als sie für das Verständnis der beobachteten optischen Phänomene und morphologischen Merkmale notwendig erscheinen.
Die polarisationsmikroskopische Bestimmung der Minerale erfolgt anhand ihrer optischen und morphologischen Kennzeichen. Umfangreiche Tabellenwerke stellen die hierfür benötigte Datenbasis für eine außerordentliche Vielzahl von natürlichen Mineralen und synthetischen Phasen bereit.
Grundlage dieses Leitfadens bildet das in langjähriger Mikroskopiepraxis bewährte, seit einigen Jahren jedoch vergriffene Clausthaler Heft 14 „Methoden der Dünnschliffmikro-skopie“von G. Müller and M. Raith. Wir haben den Text weitgehend übernommen, das Bildmaterial jedoch graphisch modern überarbeitet, mit weiteren Abbildungen ergänzt sowie die vielfältigen Phänomene mit zahlreichen Mikrofotos veranschaulicht.

description: The durability of porous building materials largely depends on the transport of liquids and dissolved salts into the material. When the moisture dries out, salts will crystallise introducing important forces in the solid matrix of the porous material. These interaction forces may result in cracking of the material. To study the salt degradation of porous building materials it is necessary to analyse in detail salt transport in (cracked) porous material. In general, salt transport modelling includes different processes: diffusive and convective salt transport, ion adsorption at the pore walls, salt crystallisation and dissolution. In this paper, we analyse in detail the experimental determination of the salt diffusion coefficient of Na2SO4 in fully water saturated ceramic brick by using a natural diffusion test. The diffusion coefficient is assumed to depend on the salt concentration. However, it appears that a rotational convective flow gives rise to a three dimensional combined diffusion convection transport.
Keywords: Salt transport, natural diffusion test, salt diffusion coefficient, rotational convective flow,

Bestimmung des Koeffizienten der Salzdiffusion in porösen Werkstoffen
Die Beständigkeit poröser Werkstoffe des Bauwesens hängt weitgehend vom Transport von Flüssigkeiten und darin gelösten Salzen in den Werkstoff hinein ab.Wenn ein Werkstoff wieder austrocknet, kristallisieren Salze im porösen Gefüge aus. Dieser Vorgang kann im Feststoffgerüst bedeutende Kräfte hervor rufen. Die Wechselwirkung mit diesen Kräften kann zur Rissbildung im Werkstoff führen. Um die zerstörende Wirkung von Salzen in porösen Werkstoffen des Bauwesens untersuchen zu können, ist es notwendig, den Salztransport in (gerissenen) Werkstoffen in seinen Einzelheiten zu analysieren. Im allgemeinen werden beim Modellieren des Salztransportes unterschiedliche Prozesse berücksichtigt: diffusiver und konvektiver Salztransport, Ionenadsorption auf den Wänden der Poren, Kristallisieren und Auflösen von Salzen. In diesem Beitrag analysieren wir Ergebnisse von Versuchen zur Bestimmung des Koeffizienten der Salzdiffusion von Na2SO4 in vollständig wassergesättigten Proben aus gebranntem Ziegelstein unter Verwendung einer natürlichen Diffusionszelle. Es wird dabei angenommen, dass der Diffusionskoeffizient von der Salzkonzentration abhängt. Es stellt sich jedoch heraus, dass rotierendes konvektives Fließen zu einem dreidimensionalen kombinierten Transport mit diffusiven und konvektiven Anteilen führt.
Stichwörter: Salztransport, natürlicher Diffusionstest, Koeffizient der Salzdiffusion, rotierendes konvektives

description: The durability and performance of specially developed restoration plasters or renders, are not always as good as expected. Salt crystallization is one of the causes of the observed degradation processes. To understand these processes in more detail, we investigated whether transport in the plasters depends on the masonry material. The transport of salt and moisture during drying of some plaster/substrate systems is followed with a Nuclear Magnetic Resonance technique. The observed differences in drying behaviour can be related to differences in pore structure between the plaster and substrate. For a good performance of the plaster a proper matching of its pore-size distribution with that of the masonry is required.
Die Beständigkeit und die Eigenschaften von eigens hergestellten Restaurierputzen und -mörteln sind nicht immer so gut wie erwartet. Salzkristallisation ist eine der Ursachen der beobachteten Schadensmechanismen. Um diese Vorgänge auch in Einzelheiten besser zu verstehen, untersuchten wir, ob der Transport in der Putzschicht vom darunter liegenden Mauerwerk beeinflusst wird. Der Transport von Salz und Wasser wurde während des Austrocknens von Systemen bestehend aus Putz und Untergrund mit Hilfe der magnetischen Kernspinresonanz (NMR) untersucht. Die beobachtbaren Unterschiede beim Austrocknen können mit den unterschiedlichen Porengefügen von Putz und Untergrund in Verbindung gebracht werden. Die Putzschicht kann die ihr zugewiesene Aufgabe nur erfüllen, wenn ihre Porengrößenverteilung auf die des Untergrunds abgestimmt ist.
