description: We revisit the impact of the jet algorithm on predictions of energy flow into gaps between hard jets, defined using the kt clustering procedure. The resulting prediction has two distinct components: a primary emission piece that is related to independent emission of soft gluons by the hard jets and a correlated emission (non-global) piece known only in the large N_c limit. We analytically compute the dependence of the primary emission term on the jet algorithm, which gives significantly more insight than our previous numerical study of the same. We also point out that the non-global component of the answer is reduced even more significantly by the clustering than suggested previously in the literature. Lastly we provide improved predictions for the latest ZEUS photoproduction data, assessing the impact of our latest findings.

description: Enterococcus faecium and Enterococcus faecalis are important causes of healthcare-associated infections in immunocompromised patients. Enterococci thrive in modern healthcare settings, being able to resist killing by a range of antimicrobial agents, persist in the environment, and adapt to changing circumstances. In Scotland, rates of vancomycin resistant E. faecium (VREfm) have risen almost 150% in recent years leaving few treatment options and challenging healthcare delivery. Resistance to the last line agent linezolid has also been detected in E. faecalis. Whole genome sequencing (WGS) allows investigation of the population structure and transmission of microorganisms, and identification of antimicrobial resistance mechanisms. The aim of this thesis was to use WGS to understand the molecular epidemiology of antimicrobial resistant enterococci from human healthcare settings in Scotland. Analysis of some of the earliest identified Scottish linezolid-resistant E. faecalis showed the resistance mechanism, optrA, was present in unrelated lineages and in different genetic elements, suggesting multiple introductions from a larger reservoir. To inform transmission investigations, within-patient diversity of VREfm was explored showing ~30% of patients carried multiple lineages and identifying a within-patient diversity threshold for transmission studies. WGS was then applied to a large nosocomial outbreak of VREfm, highlighting a complex network of related variants across multiple wards. Having examined within-hospital transmission, the role of regional relationships was investigated which showed that VREfm in Scotland is driven by multiple clones transmitted within individual Health Boards with occasional spread between regions. The most common lineage in the national collection (ST203) was estimated to have been present in Scotland since around 2005, highlighting its persistence in the face of increasing infection prevention and control measures. This thesis provides a starting point for genomic surveillance of enterococci in Scotland, and a basis for interventional studies aiming to reduce the burden of enterococcal infections.

description: Weyl superconductors feature Weyl points at zero energy in the three-dimensional (3D) Brillouin zone and arc states that connect the projections of these Weyl points on the surface. We report that higher-order Weyl superconductors can be realized in odd-parity topological superconductors with time-reversal symmetry being broken by periodic driving. Different from conventional Weyl points, the higher-order Weyl points in the bulk separate 2D first- and second-order topological phases, while on the surface, their projections are connected not only by conventional surface Majorana arcs, but also by hinge Majorana arcs. We show that the Weyl-point connectivity via Majorana arcs is largely enriched by the underlying higher-order topology and becomes anisotropic with respect to surface orientations. We identify the anisotropic Weyl-point connectivity as a characteristic feature of higher-order Weyl materials. As each 2D subsystem can be singled out by fixing the periodic driving, we propose how the Majorana zero modes in the 2D higher-order topological phases can be detected and manipulated in experiments.

description: The subject of this essay is the study of generic interaction in Ovid’s Amores. As thelatest work of a poetic genre, which had already exhausted its thematic and expressivepossibilities in its roman literary history, elegiac Amores engage in a creative andextensive dialogue with other poetic discourses and especially with epic. Thecanonical framework of this generic dialogue is provided by the programmatic elegiesAm.1.1, Am.2.1 and Am.3.1. With the unusual and witty handling of the recusatioform, these prefatory elegies reveal the moderation of generic tensions in Ovidianpoetics. Due to this deviation from the theoretical norm, Ovid is able to accommodatereadily epic markers to the elegiac poetic world of the Amores. This innovativeapproximation although between elegy and epos does not mean an indifference inAmores to the stereotyped generic categories, since epic signs, in specific passages,evoke exactly their proper poetic contexts. But this afore mentioned oppositioncollapses too semiotically in the conceit of militia amoris. By transforming the epicsignifieds of the metaphor to elegiac signifiers, Ovid incorporates organically the epicphraseology to his erotic discourse.
Diakonische Inklusion: Die Option für die Armen unter den Bedingungen des aktivierenden Sozialstaats

description: Durch ihre Bindung an die Kirchen ist den kirchlichen Wohlfahrtsverbänden ein theologisches Programm vorgegeben: Sie wirken an der Diakonie der Kirchen mit und haben dabei die Option Gottes für die Armen zu vollziehen. Dieses Programm müssen sie unter den Bedingungen eines Sozialstaats realisieren, der gegenwärtig auf die Gewährleistung von Inklusion und auf die Aktivierung der Ausgeschlossen und vom Ausschluss Bedrohten umprogrammiert wird. Nach einer kritischen Sichtung unterschiedlicher Versuche, die Option für die Armen für diese Bedingungen auszulegen, wird für diakonische Inklusion plädiert: Die kirchlichen Wohlfahrtsverbände adressieren ihre Dienste - im Rahmen der vor allem durch den Sozialstaat gegebenen Möglichkeiten – allgemein, gewähr- leisten dabei aber zugleich, dass sie von der Nutzung ihrer Dienste insbe- sondere diejenigen nicht ausschließen, die den Zugang zu diesen Diensten nur schwer finden.

 The church-based charitable organisations have a theological programme: They play a part in the ministry of charity (diakonia) and have to execute God‹s option for the poor. As they have to perform within a welfare state in transformation to workfare, this does present difficulties. After a critical sighting of different interpretations of the option for the poor the paper pleads for a diaconical inclusion: While upholding their service portfolio, the church-based charitable organisations should take care to address especially those who have difficulties to access social services.

description: Given a metabolic network in terms of its metabolites and reactions, our goal is to efficiently compute the minimal knock out sets of reactions required to block a given behaviour. We describe an algorithm which improves the computation of these knock out sets when the elementary modes (minimal functional subsystems) of the network are given. We also describe an algorithm which computes both the knock out sets and the elementary modes containing the blocked reactions directly from the description of the network and whose worst-case computational complexity is better than the algorithms currently in use for these problems. Computational results are included.

description: This study concerns the table ware (plates and small basins) that was found within the limits of a spacey house block, at the southeast part of the New University Excavation of Philippi. The pottery assemblage comes from a place that was, almost uninterruptedly, used since the second half of the 2nd or the beginning of the 3rd century until the 7th century. The fine pottery of the assemblage is studied in detail and specifically three major late roman wares, Çandarli ware, Phocaean Red Slip Ware and African Red slip ware. The presence of these pottery vessels in this assemblage proves the continuous interaction of the city with the important commercial centers of the Mediterranean, at least during the period that this specific part of the city was still in use.

description: Visual analysis of temporal networks comprises an effective way to understand the network dynamics, facilitating the identification of patterns, anomalies, and other network properties, thus resulting in fast decision making. The amount of data in real-world networks, however, may result in a layout with high visual clutter due to edge overlapping. This is particularly relevant in the so-called streaming networks, in which edges are continuously arriving (online) and in non-stationary distribution. All three network dimensions, namely node, edge, and time, can be manipulated to reduce such clutter and improve readability. This paper presents an online and nonuniform timeslicing method, thus considering the underlying network structure and addressing streaming network analyses. We conducted experiments using two real-world networks to compare our method against uniform and nonuniform timeslicing strategies. The results show that our method automatically selects timeslices that effectively reduce visual clutter in periods with bursts of events. As a consequence, decision making based on the identification of global temporal patterns becomes faster and more reliable.
Electrochemical study on the redox behavior of selenium-containing soda-lime-silica melts
Creators: name: Rüssel, Christian
Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 2001
Subjects: subject: 660

description: Decolorization of white container glasses nowadays is usually achieved by the addition of selenium compounds to the batch. Most of the quantity added, however, is evaporated during melting which is strongly influenced by the redox state of the melt. Therefore, the redox behavior in selenium-doped soda-lime-silica melts was studied by square-wave-voltammetry. The current-potential curves recorded showed two peaks, attributed to the reduction of SeO3 to SeO2 and SeO2 to Se^0. Under reducing conditions, selenium predominantly occurs as Se^0, which gives rise to the pink color. When melted under oxidizing conditions or, however, when the melt is kept at high temperature in air, the cooled glasses are nearly colorless due to the re-oxidation of Se^0 to SeO2. Keeping the melt at high temperatures for up to 50 h did not result in a notable evaporation of selenium compounds. Highest selenium contents were achieved by adding ZnSe to the batch.

description: Glass is an ideally brittle material at room temperature. The results of hardness indentation tests demonstrate this property by crack formation at the corners of the indent. But it is possible to avoid the crack formation if the load, the contact area and the deformation rate, respectively, are small enough. The mechanisms of this permanent deformation of brittle glasses by indentation close to room temperature have not been understood completely up to now. Viscous flow is responsible for permanent deformation of glasses above the transformation temperature (Tg). The same mechanism of deformation during indentation experiments is assumed in this work hypothetically, taking into account the very high stresses (GPa range) in the local volume around the indenter tip. This hypothesis of deformation at room temperature will be verified by independent experiments that work like viscometers in principle (e.g. cylinder compression experiments, ball indentation experiments). All experiments were analysed with the help of simple rheological models. Additionally some ball indents were analysed by topographical investigations to get first hints of viscoelastic deformation behaviour below Tg of glass.

description: Structure and reactivity of several commercial and laboratory granulated glassy blast furnace slags were investigated. From the compositions NBO/T was calculated, the number of nonbridging oxygens per tetrahedron. Electron spin resonance spectrometry answered questions regarding the coordination numbers of the ions Mn2+ (Mg2+) and Ti3+. Both the hydrolytic reactivity of the slag glasses in water and their corrosion mechanisms in 0.1 mol/1 KOH model pore solution were studied. Scanning electron and atomic force microscopy showed the development of gel-like phases on the slag grains. Although distinct features could be resolved already, only the nanoscale in-depth profiles obtained by secondary neutral mass spectrometry helped to enlighten the complex reaction sequences. Thus, for example, it could be shown that first Mg2+ -rich gel phases developed by the corrosion process, however, after some hours the leach solutions became supersaturated successively with the consequence of forming a secondary calciumsilicate hydrate phase by a redeposition process. This phase showed a tobermorite-like structure. AI2O3- and TiO2-rich blast furnace slags were more stable than the CaO-rich materials and they also displayed reaction mechanisms at least partly dissimilar to the just mentioned.

Analysis of Nonlinear Synchronization Dynamics of Oscillator Networks by Laplacian Spectral Methods

description: We analyze the synchronization dynamics of phase oscillators far from the synchronization manifold, including the onset of synchronization on scale-free networks with low and high clustering coefficients. We use normal coordinates and corresponding time-averaged velocities derived from the Laplacian matrix, which reflects the network's topology. In terms of these coordinates, synchronization manifests itself as a contraction of the dynamics onto progressively lower-dimensional submanifolds of phase space spanned by Laplacian eigenvectors with lower eigenvalues. Differences between high and low clustering networks can be correlated with features of the Laplacian spectrum. For example, the inhibition of full synchoronization at high clustering is associated with a group of low-lying modes that fail to lock even at strong coupling, while the advanced partial synchronizationat low coupling noted elsewhere is associated with high-eigenvalue modes.

description: By globally analyzing nuclear Drell-Yan data including all incident energies, the nuclear effects of nPDFs and initial-state parton energy loss are investigated. Based on Landau-Pomeranchuk-Migdal (LPM) regime, the calculations are carried out by means of the analytic parametrizations of quenching weights derived from the Baier-Dokshitzer-Mueller-Peign$\acute{e}$-Schiff (BDMPS) formalism and using the new EPPS16 nPDFs. It is found that the results are in good agreement with the data and the role of the energy loss effect on the suppression of Drell-Yan ratios is prominent, especially for low-mass Drell-Yan measurements. The nuclear effects of nPDFs becomes more obvious with the nuclear mass number A, the same as the energy loss effect. By global fit, the transport coefficient extracted is $\hat{q}=0.26\pm0.04$ GeV$^{2}$/fm. In addition, to avoid diminishing the QCD NLO correction on the data form of Drell-Yan ratios, the separate calculations about the Compton differential cross section ratios $R_{Fe(W)/C}(x_{F})$ at 120GeV are performed, which provides a feasible way to better distinguish the gluon energy loss in Compton scattering. It is found that the role of the initial-state gluon energy loss on the suppression of Compton scattering rations is not very important and becomes disappear with the increase of $x_{F}$.

A study of scour below Ruskin Dam spillway using a non-cohesive bed hydraulic model
Creators: name: Galvagno, Giampiero
Publisher: name: University of British Columbia
Year: 2009

description: Hydraulic models, using either cohesive or non-cohesive beds, have traditionally been employed to gauge scour below a spillway. Empirical equations, based on world-wide prototype and model experience, have been developed for estimating scour depth depth. In this study both the hydraulic modelling and analytical approach were used to assess the maximum potential scour in the rock lined channel below Ruskin Dam. Ruskin Dam, built in 1928, has an overflow spillway with seven bays discharging into a rock-lined channel. The spillway has a complex arrangement of concrete benches lining the sides and a large concrete bridge pier in directly downstream of the spillway. A non-cohesive bed, hydraulic model was employed to understand how the degree of scour is affected by the presence of the bridge pier and redirection of the spillway discharge by the concrete benches, and to locate areas of maximum scour intensity. Five scour equations were used to determine theoretical scour depths in both the prototype and model. Data on scour depths gathered from the model study was compared to the theoretical values calculated from the equations. From the model study it was shown that if the bridge pier was removed from the spillway channel the point of maximum scour moves downstream and the intensity is reduced. The location of the point of maximum scour was also influenced by gate openings. High scour intensities were recorded for gate openings where flow was deflected to one side of the channel and localized by the pier armature. The results of the scour depth comparisons using theoretical and measured model depths showed that 2 of the 5 equations reasonably represented the model scour. This result was generalized to the scour calculations using prototype data and an estimate of scour depth was made for the rock lined spillway channel below Ruskin Dam.

description: The dissolution behaviour of two types of fibres, the biosoluble HT and the traditional MMVF21 stone wool fibres, in synthetic simulated lung fluid (Gamble's solution) at pH 4.5 was investigated in order to clarify the mechanisms, and the effect of the various constituents in the liquid. The Gamble's solution contains various organic acids and salts. The study showed that organic acids which are able to form complexes with aluminium (e.g. citric and tartaric acid) caused both fibres to dissolve at a high rate at pH 4.5. Organic acids without the ability to form complexes with aluminium (e.g. acetic, maleic, lactic and pyruvatic acid) have no (or minor) impact on the dissolution rate at pH 4.5. The presence of sodium chloride lowers the dissolution rate, especially that of MMVF21. The silica that remains when the silica network has been depleted of aluminium ions (due to citric and tartaric acid) behaves differently in the two fibres. In HT fibres the silica dissolves at a high rate, probably as a diluted sol. Thus the HT fibre has a high dissolution rate in Gamble's solution at pH 4.5. For the MMVF21 fibre, condensation of the silica network as a gel results in a lower dissolution rate. It is assumed that the different Al/(Al+Si) ratios for HT and MMVF21 fibres explain why the fibres behave differently.

description: TiO2, antimony-doped dn oxide and tin-doped indium oxide coatings were prepared from sols using a spray coating procedure. Coatings prepared from ethanolic sols exhibited high surface roughness. Adding butanediole to the sols, however, resulted in smooth layers. Supposedly, butanediole prevents the evaporation of high quantities of ethanol from the surface of the droplets initially formed during spraying. The electrical conductivity of the layers formed is in the same range as those of dip coatings.

 dert eine grundlegende Transformation, die Zeit braucht, aber trotzdem jetzt
 schon angegangen werden muss. Denn ein Aufschieben dürfte die Aufgabe
 schwieriger machen und das Potential für Krisen erhöhen.

 In recent years there has been an upsurge of criti-cism of economic growth.
 The aim of this article is to establish the concept of a post-growth-society, and
 introduce relevant growth-critical discussions within this framework. The dis-
 cussions will show some similarities in the causes of growth-criticism e.g.
 GDP-criticism, some ambivalent appraisals e.g. the potential of efficiency,
 and finally, partly ignored arguments e.g. the criticism of interest. A re-
 nunciation of the growth paradigm requires a fundamental transformation
 which although needing time, should be tackled now. Postponement can only
 make the task more difficult and increase the potential for crises.

Politökonomie und Postwachstum – Bedingte Wachstumsbegrenzung durch Selbstbindung der Politik
Creators: name: Mayert, Andreas
Publisher: name: UB Tübingen
Year: 2015

description: Die vorliegende Untersuchung greift aus der um den Begriff »Postwachstum« versam-
 melten Diskussion eine Fragestellung und ein Themengebiet heraus. Sie befasst sich
 mit dem Problem der Klimaerwärmung und fragt vor diesem Hintergrund nach mög-
 lichen Gründen und Wegen zu einer bewussten Begrenzung wirtschaftlichen Wachs-
 tums. Politische Entscheidungsträger, die neben Wachstums- auch Klimaschutzziele
 verfolgen, stehen vor einem Zielkonflikt, wenn das Klimaschutzziel nur unter Inkauf-
 nahme einer Hemmung der wirtschaftlichen Aktivität erreicht werden kann. Um he-
 rauszuarbeiten, wie sie diesen Zielkonflikt lösen, wird untersucht, welche Motive das
 Handeln politischer Entscheidungsträger bestimmen. Ausgehend von einem objek-
 tiven Abwägungskriterium zwischen Wachstums- und Klimaschutzziel wird unter-
 sucht, ob politische Zwänge zu einer Verzerrung politischer Entscheidungen im Sinne
 einer zu starken Gewichtung des Wachstumsziels führen können. Aufbauend auf den
 hierbei erzielten Ergebnissen wird für eine politische Selbstbindung durch Delegierung
 der Klimaschutzpolitik an eine unabhängige, von externen Einflüssen abgeschirmte
 Institution plädiert. Es werden Anforderungen an die Ausgestaltung dieser Institution
 diskutiert und mit der Realität der EU-Klimaschutzpolitik verglichen. Abschließend
 wird der Zusammenhang zwischen der vorgeschlagenen Selbstbindung der Politik
 und der Wachstumsbegrenzungsfrage hergestellt.

 This study singles out one issue and one topic of the growing discussion gathering
 under the term «Postwachstum». It deals with the problem of global warming and
 asks in this context for possible justifications of and ways to a deliberate limiting
 of economic growth. If policy makers pursue growth and climate protection goals
 at the same time, they are facing a tradeoff, if the climate protection goal can be
 achieved only at the cost of an inhibition of economic growth. To understand how
 policy makers act under this constraint, the mo-tives that guide their decisions are
 examined. Based on an objective assessment criterion between the growth and the
 climate protection goal it is investigated whether political considerations may lead to
 a distortion of policy decisions in direction of a too strong weighting of the growth
 target. Based on the results achieved, the policy of a self-binding delegation of
 climate change policy to an independent institutional body, shielded from external
 political influences, is advocated. The required design of this institutional body is
 discussed and compared with the reality of the EU climate protection regime. Finally,
 the relationship between the proposed self-binding policy and the case for a limiting
 of economic growth is investigated.

Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 2001
Subjects: subject: 660

description: This work describes the investigation and the results for three glass types for qualification as reference materials. The measurements were carried out by means of a specially designed rotational viscometer in a temperature range from 400 up to 1400 °C and a viscosity range from about 10^2 to 10^14 dPas. Further measurements were performed in a fibre elongation viscometer to compare elongational viscosity and shear viscosity by means of the Trouton ratio. The technical design of the viscometers including calibration by tracing back to national standards is described. The uniformity of the glass types as well as the stability and reproducibility of the viscosity measurements were checked for compliance with the requirements placed on a reference material. The measurements were performed under equilibrium conditions and include the working point and the softening point (Littleton point) according to ISO 7884, part 1, to allow comparisons with techniques often used. The viscosity-temperature relationship is presented, the uncertainty of the measurements and the best-fit polynomial equation are calculated and the results are discussed.
Spawning gravel quality within the Coquitlam River: potential impacts from gravel pit mining
Creators: name: Uren, Shane L.
Publisher: name: University of British Columbia
Year: 2009

description: Potential spawning sites within the Coquitlam River were evaluated for their ability to support embryos through to the late stages of incubation. Freeze core samples were collected from four sites beginning on December 18, 1997 through to April 14, 1998. Dissolved oxygen and relative permeability data was collected from March 28, 1998 through to April 14, 1998. Sediment traps were also placed at the four sampling locations on March 20, 1998 and removed May 4, 1998 (45 days). Two of the four sites had descriptive measures (%<0.85 mm, dissolved oxygen, and Fredle index values) that classified them as 'good' quality spawning habitat. The other two sites had descriptive measures reflective of'poor' quality spawning habitat. Of the two 'poor' quality habitats, one was exposed to episodic upstream slides that were believed to be depositing fines within potential spawning gravel. The other site was directly downstream of discharge effluent from gravel mining. The impact from the gravel mining appeared to be localized. A site approximately 1.5 km downstream had 'good' quality spawning habitat whereas a sample site 0.3 km downstream had 'poor' spawning habitat. In addition, sediment trap data showed a significantly finer distribution of deposited material immediately downstream of the gravel mining outfall. Approximately 1.5 km downstream the deposited material had a significantly coarser distribution. Although it appeared that the gravel effluent was affecting gravel quality locally, attempts to trace the deposited material to the source was not successful.
Gutes Leben jenseits von Wachstum: eine ethische Perspektive
Creators: name: Muraca, Barbara
Publisher: name: UB Tübingen

description: Wachstum gilt als fundamentaler Faktor für die dynamische Stabilisierung moder-
 ner Gesellschaften und als Grundlage für sozialen Frieden und gesellschaftliche
 Reproduktion. Wir stehen allerdings sowohl vor funktionalen Einschränkungen
 eines fortwährenden Wachstums als auch vor einer Unvereinbarkeit von Wachs-
 tum mit wesentlichen Forderungen von Gerechtigkeit gegenüber heute lebenden
 und zukünftigen Generationen. Insbesondere in Südeuropa zeigen Wachstums-
 kritikerInnen, dass gerade das Wachstumsdiktat soziale Ungerechtigkeit hervor-
 bringt. Bisher ist allerdings eine ethische Auseinandersetzung mit der Wachstums-
 frage auffällig unterrepräsentiert. Dieser Beitrag analysiert den wachstumskri-
 tischen Diskurs aus einer ethischen Perspektive, anhand folgender Fragen:
 1. Ist Wachstum unter den biophysischen Bedingungen des Planeten möglich,
 können wir (noch) wachsen?
 2. Ist Wachstum inter- und intragenerationell moralisch zu rechtfertigen – dürfen
 wir wachsen?
 3. Ist Wachstum als ökonomische und gesellschaftliche Zielsetzung noch sinnvoll
 und ethisch akzeptabel? Steht es im Einklang mit unseren Vorstellungen eines
 »guten Lebens«; wollen wir noch wachsen?
 4. Wer ist wir? Wer ist mit Wirkungsmacht an dem Diskurs beteiligt?
 Nicht zuletzt ist aus ethischer Perspektive Kritik zu formulieren an den überall
 modisch gewordenen Glücksindikatoren, die das BIP ergänzen oder gar er-
 setzen sollen.

 Growth has been so far considered as an essential factor in the dynamic stabili-
 zation of modern societies and as a condition for social pacification and social
 reproduction. However, we are now faced with functional limits to growth on the
 one hand and with the seeming incompatibility of continuing growth with ethical
 issues in terms of inter- and intragenerational justice on the other. Especially in
 the Southern European countries growth critics hold that social injustice is en-
 hanced precisely by the growth-diktat. Yet, a thorough ethical scrutiny of the
 growth/degrowth debate has been so far neglected. Aim of this paper is to re-
 consider growth critique from an ethical point of view, along following questions:
 1. Is growth still possible given the biophysical conditions of our planet, i.e. can
 we still grow?
 2. Can growth be morally justified in terms of inter- and intragenerational justice,
 i.e. may we still grow?
 3. Is growth still a meaningful economic and societal goal? Is it still ethically
 acceptable? Does it harmonize with our conception of a good life, i.e. do we
 still want to grow?
 4. Who is we? Whose voices are de facto participating in the discourse?
 Moreover, the paper formulates a critique of the increasingly fashionable debate
 on happiness indicators, which are conceived as integration or replacement
 for GDP.

description: Corroded soda-lime float glass surfaces prepared in water (room temperature and 60 °C) or air (relative humidity of 95 %, 60 °C) for different times are invesdgated by means of SIMS, SNMS, XPS, NRA, ERD, RBS, GIXR, AFM, SEM, light microscopy and scratch testing. The corrosion effects are studied for as-received and cleaned glass surfaces. Changes in the dement concentration in the glass interfaces with the immersion time in water are described. They are combined with variations in density of the surface layer which exhibits plastic deformation behaviour. Inhomogeneous corrosion leads to changes in the topography and an increase in surface roughness.

 menhang von Wachstum, Wohlstand und Lebensqualität beleuchten und eine Alter-
 native zum Bruttoinlandsprodukt als Indikator für Wachstum und Wohlstand vorschla-
 gen soll. Der Beitrag beleuchtet aus der Perspektive eines Insiders die Debatten in
 der Kommission. Eine wichtige Rolle spielen die Probleme der Union, sich auf eine
 Grundlinie zu einigen, die Frage der Entkopplung von Wachstum und Ressourcenver-
 brauch und die Probleme effektiven Regierens. Der Beitrag wird durch Überlegungen
 zu den ökonomischen, sozialen und ökologischen Möglichkeiten unserer Enkel abge-
 schlossen.

 The German Bundestag has recently appointed a Study Commission on Growth,
 Welfare and the Quality of Life. Its task is to come up with an alternative to the
 gross national product as a measure for welfare and the quality of life, thus taking
 up an international debate. The article reflects – from the perspective of a member
 of the Commission – problems of the Christian Democrats to come up with a coherent
 strategy to tackle the questions of growth and prosperity with regards to social and
 ecological problems. Moreover, questions of a decoupling of growth and the use of
 resources and problems of effective governance are debated. Finally, the economical,
 ecological and social possibilities of our grandchildren are considered.

description: Η λευκοπλακία αποτελεί τη συχνότερη προκαρκινική βλάβη του βλεννογόνου του στόματος αντιπροσωπεύοντας ποσοστό περίπου 85% του συνόλου των προκαρκινικών βλαβών. Με την εξαίρεση του καπνού κανένας άλλος παράγοντας δεν έχει συσχετισθεί αιτιολογικά με την αλλοίωση αυτή. Παράγοντες όπως η κατανάλωση οινοπνεύματος-αλκοόλ, η επίδραση υπεριώδους ακτινοβολίας, οι τραυματισμοί και η δράση μικροοργανισμών όπως οι ιοί ΗPV και το είδος Candida albicans, έχουν κατά καιρούς ενοχοποιηθεί για την πρόκληση της λευκοπλακίας αλλά η συσχέτιση αυτή παραμένει ασθενής και δεν είναι ευρύτερα αποδεκτή στη διεθνή βιβλιογραφία. Στοιχεία όπως η ηλικία και το φύλο των ασθενών, ο κλινικός τύπος και η εντόπιση της λευκοπλακίας και ο βαθμός δυσπλασίας έχουν μελετηθεί με σκοπό την πληρέστερη κατανόηση του χαρακτήρα και της βιολογικής συμπεριφοράς της προκαρκινικής αυτής βλάβης. Σκοπός της παρούσας έρευνας ήταν να καταγραφούν τα παραπάνω στοιχεία των ασθενών με λευκοπλακία που επισκέφθηκαν την κλινική Στοματολογίας της Οδοντιατρικής Σχολής του Α.Π.Θ. και να μελετηθούν οι πιθανές συσχετίσεις της νόσου μ’ αυτές τις παραμέτρους.
description: Oral leukoplakia is the most common premalignant lesion of the oral cavity with a magnant transformation rate of dysplastic lesions as high as 50%. The sex and age of patients, the clinical subtype and the anatomic location of oral leukoplakia, the presence of dysplasia and the tobacco use by the patients are factors associated with higher rates of malignant transformation. The present study examines the co-relation among the above factors in a group of patients with oral leukoplakia that seek tratment at the School of dentistry of Aristotle University of Thessaloniki.
