Subjects: M-GGR/02 Geografia economico-politica

description: Per bonifica si intende quella attività di progettazione, esecuzione, manutenzione ed esercizio della rete idrografica, dei manufatti, degli impianti idrovori e di sollevamento, avente la finalità di mettere in sicurezza i territori urbanizzati e produttivi - che altrimenti sarebbero soggetti ad inondazioni o a dissesti idrogeologici - e di rendere coltivabili i terreni mediante irrigazione.
L’attività di bonifica riveste quindi due funzioni che si integrano in un delicato equilibrio, da una parte la bonifica si pone a salvaguardia del territorio, dall’altra consente il razionale sviluppo  dello stesso sia a fini strettamente agricoli sia a fini produttivi (Lenzi, 2001, p.4).

description: We give a direct proof of the Harnack inequality for a class of Kolmogorov operators associated with a linear SDE and we find the explicit expression of the optimal Harnack constant. We discuss some possible implication of the Harnack inequality in finance: specifically we infer no-arbitrage bounds for the value of self-financing portfolios in terms of the initial wealth.

description: Bei der Produktion von konventionellen Portlandzementen (PZ) und Tonerdezementen (TZ) werden hohe Herstellungstemperaturen benötigt. Zusätzlich werden durch die Decarbonatisierung des CaCO3 enorme Mengen an CO2 emittiert (0,63tCO2/tPZ). Deshalb wird derzeit versucht CaO-ärmere Zemente herzustellen und auch die Zementfraktion von Alt-Beton durch Dehydratisierung wieder zu verwenden. In der hier vorgelegten Arbeit ist die Bildung der Verbindungen des PZ und TZ bei einer optimalen Homogenisierung der Ausgangsstoffe beschrieben. Es wurden die bei niedrigen Sintertemperaturen entstehenden Phasen charakterisiert und deren Hydratationsverhalten untersucht. Dabei konnte gezeigt werden, dass sich im Vergleich zur konventionellen Herstellung einige metastabile kalkärmere Phasen oder Modifikationen bei erheblich niedrigeren Sintertemperaturen herstellen lassen und dabei deutlich höhere hydraulische Reaktivitäten besitzen.

description: Die Diskussion um „Massenmedien und Gewalt“ ist ein Thema, welches in der Öffentlichkeit immer wieder auftaucht. Aufgrund der sich rasant entwickelnden Technologien prägen die Medien den Alltag von Kindern und Jugendlichen immer stärker. Das zieht die Verbreitung von medialer Gewalt nach sich. Diese kann besonders anfällige Kinder und Jugendliche beeinflussen, wirkt sozialethisch desorientierend und fördert die Nachahmung der medialen gewalttätigen Verhaltensmodelle im realen Leben. Die Vielfalt von medialen Gewaltangeboten kann dazu führen, dass Medien eine dominierende Rolle im Leben der Kinder und Jugendlichen übernehmen, wobei besonders das Fernsehen ihr Denken und Handeln stark beeinflusst. Die Erfahrungen, die Kinder und Jugendliche mit Medien machen, finden dabei in erster Linie in der Familie statt. Von dort werden sie in die Gleichaltrigengruppe getragen. Medien stellen nicht den alleinigen Faktor dar, der zu aggressiven Verhaltensweisen führen kann, sondern es gibt weitere Faktoren wie das familiäre Umfeld, die Sozialisationsbedingungen und die Peergroup, die ebenfalls eine wichtige Rolle bei der Entwicklung aggressiven Verhaltens spielen können.

description: In dieser Dissertationsschrift versuche ich klar zu machen, dass wir nicht die Tatsache aus dem Blick verlieren sollten, dass das „ethische Modell“ hinter der populären Sichtweise, welche “gemeindebasierten” Tourismus ausschließlich als prinzipielles Modell in enger Verbindung mit weiteren humanistischen Werten darstellt, vor allem ein hochentwickeltes modernes Tourismusprodukt ist. Was dies praktisch bedeutet, ist, dass “gemeindebasierter Tourismus” ein „Nischenmarkt“ ist, der in einer sich ausdehnenden und globalen Marktindustrie wirkt. Tourismus im Dorf Canhane, in dem südafrikanischen Staat Mozambique, ist ein Feld moralischer “agency”, mit der “Entwicklungsindustrie” als Hauptsystem, das die moralischen Werte im touristischen Konsum formt. Überdies werden diese moralischen Werte durch die Förderung des “Gemeindeentwicklung” angewendet, und es ist die Ausgefeiltheit dieser Aktivität innerhalb der Tourismus-Spezialität („gemeindebasierter Tourismus“, welche zur Kommodifizierung der Moral in Canhane geführt hat.

Erfassen bestehende makroökonometrische Wanderungsmodelle grundsätzlich regionale Determinanten der Wanderung gut, wurden Humankapitaleffekte bislang nicht be-rücksichtigt. Die Arbeit beschreibt einen Weg, auch in einem makroökometrischen Modell die Wirkung von Humankapital zur Erklärung aggregierter Migrationsströme zwischen deut-schen NUTS 3 Regionen zu berücksichtigen. Zu erwartende Investitionen in Humankapital wirken im Ergebnis migrationshemmend.

description: In the solution of ill-posed problems by means of regularization
methods, a crucial issue is the computation of the regularization
parameter. In this work we focus on the Truncated Singular Value
Decomposition (TSVD) and Tikhonov method and we define a method for
computing the regularization parameter based on the behavior of
Fourier coefficients. We compute a safe index for truncating the
TSVD and consequently a value for the regularization parameter of
the Tikhonov method. An extensive numerical experimentation is
carried out on the Hansen's Regtool test problems and
the results confirm the effectiveness and robustness of the method
proposed.
The impact of motives, prices and norms on sustainable fashion consumption

description: Die Literatur zeigt, dass nachhaltiger Konsum durch egoistische und biosphärische Motivaktivierung, jedoch auch durch den Kaufpreis nachhaltiger Produkte und durch soziale Validierung, beispielsweise in Form von Empfehlungen durch Freunde, beeinflusst werden kann. Bisher ist jedoch unklar, ob der Einfluss dieser Faktoren sich additiv verstärkt oder ob sie unabhängig voneinander wirksam sind. Die folgenden Experimente testen daher die Interaktion egoistischer und biosphärischer Motive mit verschiedenen Produktpreisen für nachhaltige Mode oder verschiedenen sozialen Einflussquellen, um den Konsum nachhaltiger Textilien zu stimulieren. Während sich biosphärische Motive eher bei gleichem Produktpreis für nachhaltige und konventionelle Mode kaufsteigernd auswirkten, waren egoistische Motive eher bei höherpreisigen Produkten wirksam. Auch soziale Validierung wirkte sich kaufsteigernd auf nachhaltige Textilien aus, jedoch unabhängig von der Motivaktivierung.
description: Literature confirms that sustainable consumption is driven by attitudinal components, like biospheric and egoistic motivation, but also by the price of sustainable products and social influence – transported by the approval or disapproval of close peers. It is however not clear whether the positive effects of these factors add up or affect behavior in an independent way. The chief objective of the present experiments was therefore to test whether the interaction of egoistic and biospheric motives with different prices for sustainable textiles or different socialization agents increase the purchase of sustainable textiles. Our results showed that biospheric motives seem to provide a stable base for the promotion of sustainable textiles but egoistic motives are better promoters, if connected to costlier textiles. The recommendation of close peers affected sustainable consumption independent of the motivation, if the recommendation was strengthened by a credible source.

description: We investigate within a coarse-grained model the conditions leading to the appearance of Fano resonances or anti-resonances in the conductance spectrum of a generic molecular junction with a side group (T-junction). By introducing a simple graphical representation (parabolic diagram), we can easily visualize the relation between the different electronic parameters determining the regimes where Fano resonances or anti-resonances in the low-energy conductance spectrum can be expected. The results obtained within the coarse-grained model are validated using density-functional based quantum transport calculations in realistic T-shaped molecular junctions.

description: A two-week-old Jersey calf was brought to the ANDUAT veterinary clinical complex at Kumar Ganj, Ayodhya, UP, since it had been unable to walk or stand correctly from birth and had an incorrect forelimb placement. Bilateral congenital flexor tendon contracture was the diagnosis made after a physical and clinical examination of the calf. The calf was given anaesthesia and laid unconscious. The metacarpal region's caudal side was prepared aseptically. A POP was placed after surgery, along with a superficial and deep digital flexor tenotomy. On the fourteenth day following surgery, the calf was able to walk and place his forelimb appropriately.

description: The image denoising and segmentation is a fundamental task in many
medical applications based on magnetic resonance image processing.
This problem can be solved by means of nonlinear diffusive filters
requiring  the solution of evolutive partial differential equations.
In this work a coupled system of linear and nonlinear
diffusion-reaction equations is proposed and tested for denoising
and segmentation of magnetic resonance images. The discretization of
the coupled system by means of the Finite Element method is
reported. The effectiveness of the model has been tested on MR
images affected by gaussian, impulsive noise and also in the case of
dynamic magnetic resonance images where the data are affected by
noise in the frequency domain.

Mammary tumour-induced dysregulation in hematopoiesis and DC development and the role of Lyn tyrosine kinase in DC activation
Creators: name: Chehal, Manreet Kaur
Publisher: name: University of British Columbia
Year: 2014

description: Previous studies have revealed that perturbations in myelopoiesis can lead to the emergence of immature cells, which can facilitate tumorigenesis and metastasis. Our studies showed that mammary tumours led to a myeloproliferative-like disease, characterized by anemia, leukocytosis, expansion of immature myeloid cells, and defects in the hematopoietic stem and progenitor cell (HSPC) compartment in tumour-bearing mice. Furthermore, mammary tumours impaired DC development resulting in the accumulation of DC progenitors and the emergence of immunosuppressive DCs with impaired ability to activate NK and T cells. Mammary tumour-bearing mice exhibited a shift in hematopoiesis from the bone marrow to the spleen, with large numbers of primitive and committed progenitors accumulating in the spleen. Mammary tumour development was also associated with epigenetic modifications that facilitated the expression of key hematopoiesis and leukemia regulatory genes, such as Hoxa9, a gene that critically controls HSPC differentiation. Using in vitro assays, we identified mammary tumour derived G-CSF as the factor mediating the dysregulation of the HSPC compartment and suppressing DC development. DCs are critical for the priming/activation of NK cells and cytotoxic T lymphocytes, which together are critical components of the anti-tumour immune response. Therefore, proper regulation of signaling thresholds is critical for DC activation and function. Lyn tyrosine kinase is important in regulating signaling thresholds in immune cells, including DCs, and Lyn gain-of-function (Lynup/up) mice show increased sensitivity to PAMPs (i.e. LPS) characterized by high levels of proinflammatory cytokines and increased susceptibility to endotoxin-mediated death. Our studies demonstrated that DCs were necessary for the enhanced LPS-induced inflammation in Lynup/up mice, by priming excessive IFN-γ production by NK cells. As such, we hypothesized that enhanced Lyn activity, and the associated changes in DC development and activation will evoke improved anti-tumour immune responses and preliminary data from our lab demonstrates that Lynup/up mice develop smaller mammary tumours than wild type mice. Taken together, our results suggest that targeting mammary tumour derived G-CSF may reverse mammary tumour-induced anemia, leukocytosis, and DC defects, conversely enhancing DC function by increasing Lyn activity may result in in a more robust anti-tumour immune response, leading to increased survival of breast cancer patients.

description: Singular Green operators G appear typically as boundary correction terms in resolvents for elliptic boundary value problems on a domain Ω\subset R^n, and more generally they appear in the calculus of pseudodifferential boundary problems. In particular, the boundary term in a Krein resolvent formula is a singular Green operator. It is well-known in smooth cases that when G is of negative order -t on a bounded domain, its eigenvalues or s-numbers have the behavior (*) s_j(G) \sim c j^{-t/(n-1)} for j\to \infty, governed by the boundary dimension n-1. In some nonsmooth cases, upper estimates (**) s_j(G) \le Cj^{-t/(n-1)} are known. We show that (*) holds when G is a general selfadjoint nonnegative singular Green operator with symbol merely Hölder continuous in x. We also show (*) with t=2 for the boundary term in the Krein resolvent formula comparing the Dirichlet and a Neumann-type problem for a strongly elliptic second-order differential operator (not necessarily selfadjoint) with coefficients in W^1_p(Ω) for some p>n.

description: The paper addresses the problem of evaluation of the effectiveness of Active Labour Policies in the province of Bologna, a manufacturing district in Northern Italy, during the period 2004/2006. Using  surviving analysis  through Kaplan Meier  filter and a new approach to propensity score computation, the Authors shows that the policies run by the Labor Market Authorities are able to compensate the disavatanges that secondary labor forces such as migrants, old age or less educated workers have in getting a job when fired. Moreover, they put new light on the transitions from temporary job to permanent jobs,  and show that the probability of transitions is very low.

Die Retentionskraft wurde in Abzugsversuchen auf Implantatangulationen von 0°, 5°, 10°, 15° und 20° über 10.000 Ein- und Ausgliederungszyklen im Kausimulator erfasst. Die initiale Retentionskraft von NG=8,61,0 N, LR=19,48,2 N, und LO=8,95,3 N sank nach der mechanischen Alterung auf ∑NG=6,30,7 N, LR=6,52,6 N und LO=1,01,0 N. Im Vergleich zu LR und LO zeigte NG keine klinisch relevanten Unterschiede zwischen verschiedenen Implantatangulationen. NG zeigte über den Alterungsprozess ein beständigeres Retentionsverhalten als LR und LO.
description: Prefabricated stud attachments with removable implant anchored dentures have become an established treatment concept. This laboratory study compares retention force changes of an attachment system (Locator) with pink (LR) and orange (LO) nylon inserts to the Novaloc system with yellow polyetheretherketone (PEEK) inserts and 0° (NG0) and 15° (NG15) patrices. The retention force was measured by dislodging on implant angulations of 0°,5°,10°,15° und 20° through 10,000 cycles of insertion and removal in the chewing simulator. The initial retention force of NG=8.61.0 N, LR=19.48.2 N and LO=8.95.3 N decreased by ageing simulation to ∑NG=6.30.7 N, LR=6.52.6 N and LO=1.01.0 N. In contrast to LR and LO, the retention forces of NG showed no clinically relevant dependence on different implant angulations. The retention of NG was more enduring than LR and LO.

description: In this paper, a decision support system (DSS) for an integrated coastal management (ICM) is
developed, where decisions arise from a maximisation algorithm, the stakeholders’ involvement in
the choice among alternative management strategies is favoured, complicated assessment
procedures for non-economical indicators or relative weights to combine economic, social and
environmental indicators are not used, the integration between economic activities and
environmental status is depicted by referring to initial and sustanability conditions, both human and
environmental dynamics are taken into account, a spatial structure is adopted, by finding a
compromise between economic information (available at macro-level) and ecological information
(available at micro-level), several economic, social and environmental policies are considered,
predictions are based on a knowledge base that can be easily collected and that is reasonably
reliable, by calculating the confidence level of results. Its application to Reghaa and Heraoua
municipalities, Algeria, suggests that the suggested DSS for an ICM meets all design and role
characteristics required by Westmacott (2001) Journal of Environmental Management 62: 55-74.

description: Questo contributo, che prende spunto da una recente Tesi di Dottorato, concerne lo studio di alcune espressioni verbali della “futurità” verbale in tre lingue indoeuropee – il francese, l'italiano e l'inglese.  In particolare, ci si focalizzerà su un’analisi delle forme verbali più diffuse ed attestate per la manifestazione della nozione di “futurità”, cioè il futuro semplice ed anteriore – francese e italiano –  will/shall semplice, composto e contratto – inglese –  ma anche tutta una serie di perifrasi definite “futuri perifrastici”.  
Il lavoro è condotto attraverso la considerazione di un corpus trilingue, raccolto a partire dalla sezione dell’economia di tre quotidiani – Le Figaro, Corriere della sera, The Times – in un lasso temporale di due mesi (1° gennaio 20007 – 28 febbraio 2007).  L’indagine, coadiuvata dall’inserimento dei dati all’interno del software AntConc3.2.1, consiste in uno spoglio dapprima quantitativo, poi qualitativo, dei dati, con osservazioni di carattere comparativo e contrastivo,.  
Ci si propone anzitutto di mettere in evidenza le relazioni esistenti tra gli indici della “futurità” rilevati e il discorso di divulgazione economica, in modo da reperire la proporzione e la funzione svolta dalle forme verbali trattate, nonché il ruolo rivestito dalla “futurità” nell’ambito del discorso di divulgazione economica della stampa non specializzata.
Genetic architecture of neurogenesis in the adult mouse forebrain : insights from quantitative trait locus analyses
Creators: name: Poon, Fong-Yee
Publisher: name: University of British Columbia
Year: 2014

description: Neural stem cells and their precursors, collectively referred to as neural progenitor cells (NPCs), are present in discrete regions of the mature brain, namely the subgranular zone (SGZ) of the dentate gyrus, the subventricular zone (SVZ), and rostral migratory stream (RMS). These NPCs divide and give rise to new neurons in a process called adult neurogenesis. Genetic influence is a major determinant of adult neurogenesis. However, the genetic architecture underlying NPC proliferation and differentiation is poorly understood. My thesis aims to gain insights into the genes regulating NPC proliferation using a phenotypic-driven, genome-wide approach. I first examined nine inbred mouse strains housed in the same condition and across different ages from 60 days (P60) to 2 years. Wide inter-strain differences and negative impact of age on the number of NPCs were observed in the RMS. Genetic background had a significant effect on NPC proliferation and it also differentially influenced the effect of age on this process. The most dramatic inter-strain difference was detected at P60. Heritability estimated ~50% of the differences in NPC numbers were attributed to the genetic variation among the strains. I used quantitative trait locus (QTL) mapping to survey the entire genome for chromosomal segments referred to as QTLs that contribute to the phenotypic differences. Two panels of recombinant inbred strains, AXB/BXAs and BXDs, were employed for QTL mapping. Genetic variation in QTLs on chromosome (Chr) 6 and 11 were significantly associated with the differences in NPC numbers in the RMS. Additional analyses revealed potential interaction of Chr 6 QTL with other loci. These QTLs are hypothesized to harbor genes important for NPC proliferation and downstream experimentation is required to validate the function of these genes. As proof of concept, a candidate gene called Galanin receptor 2 (Galr2) in the Chr 11 QTL was demonstrated to be a pro-proliferative regulator of NPCs using in vitro techniques manipulating Galr2 expression and Galr2 knockout mice. In summary, I identified novel QTLs underlying NPC proliferation and these loci serve as starting points to identify genes (e.g. Galr2) critical to this process.

description: Interventionen unter dem Europäischen Landwirtschaftsfonds für die Entwicklung des Ländlichen Raums 2007-2013, die „Netzwerken“ und „New modes of Governance“ in ihr instrumentelles Konzept einschließen, sind LEADER, zur Unterstützung integrierter Entwicklung ländlicher Regionen, und die Nationalen Netze für den Ländlichen Raum (NNLRe). Diese Studie untersucht die mit der Implementierung beider Instrumente in dem neuen EU Mitgliedstaat Rumänien verbundenen Herausforderung und Potentiale. Da sozioökonomische, kulturhistorische und politisch-administrative Rahmenbedingungen die Implementierung von Politikinstrumenten determinieren, kommen Zweifel über den Erfolg von LEADER und dem NNLR in dem post-sozialistischen Land mit wenig Erfahrungen in integrierter ländlicher Entwicklung, Dezentralisierung und partizipativen Politikansätzen auf. Unter der Anwendung Sozialer Netzwerkanalyse, Multiple Criteria Decision Analysis, Policy Mapping und dem Standard Cost Model für administrative Kosten wird gezeigt, dass in Rumänien zwar die Idee (EU-weiten) Netzwerkens und resultierende befähigende Wirkungen auf fruchtbaren Boden fallen, dass jedoch die effektive Umsetzung instrumenteller Governancemechanismen, wie lokale Public-Private Partnerships und Netzwerk-Governance auf nationaler Ebene, in naher Zukunft nicht absehbar ist.
description: Two interventions under the European Agricultural Fund for Rural Development in the period 2007-2013 include elements of networking and new modes of governance in their instrumental design; these are LEADER, under which integrated regional rural development is supported, and the National Rural Networks (NRNs). This study examines the challenges and potentials associated with the implementation of these instruments in the new EU member state Romania. As the socio-economic, historico-cultural and politico-administrative context determines policy instruments’ implementation, doubts arise about the success of LEADER and the NRN in that post-socialist country, with little experience in integrated rural development, decentralization, and participatory policy-making. By applying Social Network Analysis, Multiple Criteria Decision Analysis, Policy Mapping and the Standard Cost Model on administrative costs, it is revealed that while (EU-wide) networking and its enabling effects fall on fertile ground in Romania, making effective use of new modes of governance, such as local public-private partnerships and network governance at the national level remain a long time off.

Phys., vol. 52 (2011) p. 082303), providing a theory that is based on spinor electrodynamics, is described by a system of partial differential equations in 3+1 dimensions, but reproduces unitary evolution of a quantum field theory in the Fock space. To this end, after introduction of a complex four-potential of electromagnetic field, which generates the same electromagnetic fields as the initial real four-potential, spinor field is algebraically eliminated from the equations of spinor electrodynamics. It is proven that the resulting equations for electromagnetic field describe independent evolution of the latter and can be embedded into a quantum field theory using a generalized Carleman linearization procedure. The theory provides a simple and at least reasonably realistic model, valuable for interpretation of quantum theory. The issues related to the Bell theorem are discussed.

description: Die Haftung zweier Obturationsmaterialien an Wurzelkanalwänden und mögliche Veränderungen durch Spüllösungen wurden bestimmt. Nach erfolgter Spülung wurden die Kanäle mit Guttapercha/AH Plus oder RealSeal (Resilon)/RealSeal SE gefüllt. Die Wurzeln wurden in dünne Scheiben geschnitten und das Wurzelfüllmaterial herausgedrückt. AH Plus zeigte keine signifikanten Veränderungen der Haftfestigkeit in Abhängigkeit vom Spülprotokoll. Die Haftwerte von RealSeal SE bei einer alleinigen Spülung mit isotonischer Kochsalzlösung waren zwar tendenziell niedriger, aber nicht signifikant verschieden von AH Plus. Allerdings schwankten beim adhäsiven Wurzelfüllmaterial die Ergebnisse in Abhängigkeit von der Art der Vorbehandlung. So verringerte sich die Haftung beim Einsatz von Natriumhypochlorit (ohne Abschlussspülung), EDTA und CHX auf ungefähr die Hälfte der entsprechenden Kontrollgruppe und lag damit signifikant unter den Werten von AH Plus. Im Rahmen dieser In-vitro-Studie lässt sich schlussfolgern, dass das neuartige Wurzelfüllmaterial Resilon/RealSeal SE keine Verbesserung in Bezug auf die Haftfestigkeit an der Wurzelkanalwand gegenüber einer Obturation mit Guttapercha/AH Plus erzielt.
description: We investigated the influence of different endodontic irrigants on the push-out bond strength of the obturation materials RealSeal SE and AH Plus. In our study, 200 human root canals were prepared and divided into two groups according to the filling material. Each group was divided into five subgroups according to the irrigation protocol [0.9% saline (control), 3% NaOCl, 3% NaOCl with saline, 17% EDTA, and 2% CHX]. After obturation, roots were sliced into 1-mm discs for push-out assessment. Two-way analysis of variance and the Kruskal–Wallis test were performed for pair-wise comparisons. AH Plus exhibited a significantly higher bond strength than RealSeal SE, except with saline alone. Within the AH Plus groups, no significant differences existed between the irrigants. The bond strength of RealSeal SE with saline alone or with NaOCl and saline did not differ from that of AH Plus with saline alone. However, the push-out bond strength of RealSeal SE decreased by approximately half (compared with RealSeal SE with saline alone) after rinsing with NaOCl alone, EDTA, or CHX. Conclusion: The bond strength of RealSeal SE is highly influenced by the irrigant used.

description: We prove that the simplicial boundary of a CAT(0) cube complex admitting a proper, cocompact action by a virtually $\integers^n$ group is isomorphic to the hyperoctahedral triangulation of $S^{n-1}$, providing a class of groups $G$ for which the simplicial boundary of a $G$-cocompact cube complex depends only on $G$. We also use this result to show that the cocompactly cubulated crystallographic groups in dimension $n$ are precisely those that are \emph{hyperoctahedral}. We apply this result to answer a question of Wise on cocompactly cubulating virtually free abelian groups.

Modelling the structural variation of quartz and germanium dioxide with temperature by means of transformed crystallographic data

description: The pseudocubic (PC) parameterization of O4 tetrahedra [Reifenberg & Thomas (2018). Acta Cryst. B74, 165–181] is applied to quartz (SiO2) and its structural analogue germanium dioxide (GeO2). In α‐quartz and GeO2, the pseudocubes are defined by three length parameters, aPC, bPC and cPC, together with an angle parameter αPC. In β‐quartz, αPC has a fixed value of 90°. For quartz, the temperature evolution of parameters for the pseudocubes and the silicon ion network is established by reference to the structural refinements of Antao [Acta Cryst. (2016 ), B72, 249–262]. In α‐quartz, the curve‐fitting employed to express the non‐linear temperature dependence of pseudocubic length and Si parameters exploits the model of a first‐order Landau phase transition utilized by Grimm & Dorner [J. Phys. Chem. Solids (1975), 36, 407–413]. Since values of tetrahedral tilt angles about ⟨100⟩ axes also result from the pseudocubic transformation, a curve for the observed non‐monotonic variation of αPC with temperature can also be fitted. Reverse transformation of curve‐derived values of [Si+PC] parameters to crystallographic parameters a, c, xSi, xO, yO and zO at interpolated or extrapolated temperatures is demonstrated for α‐quartz. A reverse transformation to crystallographic parameters a, c, xO is likewise carried out for β‐quartz. This capability corresponds to a method of structure prediction. Support for the applicability of the approach to GeO2 is provided by analysing the structural refinements of Haines et al. [J. Solid State Chem. (2002), 166, 434–441]. An analysis of trends in tetrahedral distortion and tilt angle in α‐quartz and GeO2 supports the view that GeO2 is a good model for quartz at high pressure.
description: A pseudocubic parameterization of the O4 tetrahedra of quartz and its structural analogue GeO2 at variable temperatures allows direct calculation of tetrahedral tilt angle, the microscopic order parameter of the α↔β phase transition. The crystal structures at interpolated or extrapolated temperatures can also be predicted.
Metallicity-Dependent Galactic Isotopic Decomposition for Nucleosynthesis

description: All stellar evolution models for nucleosynthesis require an initial isotopic abundance set to use as a starting point. Generally, our knowledge of isotopic abundances of stars is fairly incomplete except for the Solar System. We present a first model for a complete average isotopic decomposition as a function of metallicity. Our model is based on the underlying nuclear astrophysics processes, and is fitted to observational data, rather than traditional forward galactic chemical evolution modeling which integrates stellar yields beginning from big bang nucleosynthesis. We first decompose the isotopic solar abundance pattern into contributions from astrophysical sources. Each contribution is then assumed to scale as a function of metallicity. The resulting total isotopic abundances are summed into elemental abundances and fitted to available halo and disk stellar data to constrain the model's free parameter values. This procedure allows us to use available elemental observational data to reconstruct and constrain both the much needed complete isotopic evolution that is not accessible to current observations, and the underlying astrophysical processes. Our model finds a best fit for Type Ia contributing \simeq 0.7 to the solar Fe abundance, and and Type Ia onset occurring at [Fe/H]\simeq -1.2.

description: Abstract:
The aim of this paper is to identify the pricing factor structure of Italian equity returns. The Italian Stock Market is characterized mainly by small quoted firms. Small stocks have higher beta but beta differences are not enough to explain returns differences. We investigate how these differences can be explained by other factors like size, value and momentum. A two step empirical analysis is provided where first we estimate an unrestricted multi-factor model to test if there is any evidence of mispecification. Secondly, we estimate the restricted model, with pricing errors equal to zero, through the Generalized Methods of Moments (GMM). In accordance with the main literature (see e.g. Fama and French 1992, 1993) we find that the size premium for stocks is confirmed for a domestic Italian investor. On the contrary the value premium is statistically weakly different from zero. Finally, augmenting the model with a momentum factor does not improve its performance.
A Higher Order GUP with Minimal Length Uncertainty and Maximal Momentum

description: We present a higher order generalized (gravitational) uncertainty principle (GUP) in the form $[X,P]=i\hbar/(1-βP^2)$. This form of GUP is consistent with various proposals of quantum gravity such as string theory, loop quantum gravity, doubly special relativity, and predicts both a minimal length uncertainty and a maximal observable momentum. We show that the presence of the maximal momentum results in an upper bound on the energy spectrum of the momentum eigenstates and the harmonic oscillator.

description: We investigate the effect of backreaction due to inhomogeneities on the evolution of the present universe by considering a two-scale model within the Buchert framework. Taking the observed present acceleration of the universe as an essential input, we study the effect of inhomogeneities in the future evolution. We find that the backreaction from inhomogeneities causes the acceleration to slow down in the future for a range of initial configurations and model parameters. The present acceleration ensures formation of the cosmic event horizon, and our analysis brings out how the effect of the event horizon could further curtail the global acceleration, and even lead in certain cases to the emergence of a future decelerating epoch.

description: For n greater or equal 4 we discuss questions concerning global fixed points for isometric actions of Aut(Fn), the automorphism group of a free group of rank n, on complete CAT(0) spaces. We prove that whenever Aut(Fn) acts by isometries on complete d-dimensional CAT(0) space with d is less than 2 times the integer function of n over 4 and minus 1, then it must fix a point. This property has implications for irreducible representations of Aut(Fn), which are also presented here. For SAut(Fn), the unique subgroup of index two in Aut(Fn), we obtain similar results.

description: Ziel dieser In-vitro-Studie war der Vergleich press- und schichtkeramisch verblendeter CoCr- und ZrO2-Gerüst-Kronen. Auf 80 Metallstümpfen wurden je 40 zervikal eingekürzte, CAD/CAM-gefertigte CoCr- und ZrO2-Gerüstehergestellt, von denen je 30Gerüste mit verschiedenen Presskeramiken der Zahnfarbe A3 und je 10 Gerüste als Referenz mit Schichtkeramiken verblendet wurden. Nach der Zementierung erfolgten die lichtmikroskopische Vermessung des vertikalen Randspaltes und digitale Zahnfarbbestimmung. Danach wurde die Hälfte aller Kronen einer Materialkombination mechanischen und thermischen Belastungswechseln unterzogen. Abschließend erfolgten die Überprüfung der Bruchfestigkeit im Druckversuch und die deskriptive Analyse der Bruchmodi. Mit beiden Verblendtechniken ließen sich bezüglich der vertikalen Passgenauigkeit und Bruchfestigkeit vergleichbare klinisch akzeptable Ergebnisse erzielen. Hinsichtlich der Farbwiedergabe erwies sich die Schichtkeramik der Presskeramik überlegen. Korrekturmaßnahmen zeigten bei Presskeramiken einen stabilisierenden Einfluss auf deren Resistenz gegenüber thermischen Wechsellasten.
description: The objective of this in-vitro-study was the comparison of CoCr- and ZrO2-crowns with pressed or layered veneer. On 80 metal dies, 40 cervical shortened CoCr- and ZrO2-frameworks were fabricated using CAD/CAM-technology, 30 frameworks of each material were veneered with different pressed ceramics of tooth shade A3, 10 frameworks were veneered with layered ceramics and served as reference. After cementation, vertical marginal gap measurement using light microscope and digital tooth shade measurement were undertaken. Subsequently, half of the crowns made of one material combination underwent cyclic mechanical loading and thermal undulation. Finally, fracture strength was determined by pressure test and fracture mode was assessed descriptively.With both veneering technologies comparable acceptable clinical results were achieved concerning marginal discrepancy and fracture strength. With regard to color reproduction, the layering techniques provided to be superior to the pressing technique. Corrective actions seemed to improve the pressed ceramics resistance against thermal undulation.
