description: Il lavoro considera il ruolo del risparmio delle famiglie nella moderna economia industriale . Si sostiene che un aumento del risparmio delle famiglie deprime profitti aziendali e conduce a disavanzi pubblici . Dal punto di vista della politica di piena occupazione il risparmio delle famiglie è più problematico del risparmo aziendali poiché , a differenza di quest'ultimo , esso non stimola le decisioni di investimento . Alla luce di questo la questione della distribuzione funzionale cessa di essere l'unico motivo di preoccupazione , e la questione della disuguaglianza dei redditi personali si sposta in primo piano. Così la considerazione del trend di risparmio delle famiglie può comportare un certo cambiamento di atteggiamenti di economisti interessati alla piena occupazione . The work considers the role of household saving in the modern industrial economy. It is argued that an increased saving of households depresses business profits and leads to government deficits. From the point of view of full employment policy household savings are more troublesome than business savings because, unlike the latter, they do not stimulate investment decisions. In light of this the question of functional distribution ceases to be the only matter of concern, and the question of the inequality of personal incomes moves to the foreground. Thus the consideration of the trend of household saving may involve a certain shift in attitudes of economists interested in full employment. JEL: E21, H31, O16

description: The question of controllability is investigated for a quantum control system in which the Hamiltonian operator components carry explicit time dependence which is not under the control of an external agent. We consider the general situation in which the state moves in an infinite-dimensional Hilbert space, a drift term is present, and the operators driving the state evolution may be unbounded. However, considerations are restricted by the assumption that there exists an analytic domain, dense in the state space, on which solutions of the controlled Schrodinger equation may be expressed globally in exponential form. The issue of controllability then naturally focuses on the ability to steer the quantum state on a finite-dimensional submanifold of the unit sphere in Hilbert space -- and thus on analytic controllability. A relatively straightforward strategy allows the extension of Lie-algebraic conditions for strong analytic controllability derived earlier for the simpler, time-independent system in which the drift Hamiltonian and the interaction Hamiltonia have no intrinsic time dependence. Enlarging the state space by one dimension corresponding to the time variable, we construct an augmented control system that can be treated as time-independent. Methods developed by Kunita can then be implemented to establish controllability conditions for the one-dimension-reduced system defined by the original time-dependent Schrodinger control problem. The applicability of the resulting theorem is illustrated with selected examples.

description: Numerical simulation plays an important role in the study of structure formation of the universe. However, the mass resolution in current simulations is still poor. Due to technical difficulties, it is necessary to use both greatly reduced number density of particles and greatly raised unit particle mass. Consequently, the particle masses used in cosmological simulations are about $10^{70}$ times larger than the $Gev$ candidates in particle physics. This is a huge physical bias that cannot be neglected when interpreting the results of the simulations. Here we discuss how such a bias affects Cold Dark Matter (CDM) cosmological simulations. We find that the small scale properties of the CDM particle system are changed in two aspects. 1) An upper limit is imposed on the spatial resolution of the simulation results. 2) Most importantly, an unexpected short mean free path is produced, and the corresponding two body scattering cross section is close to the value expected in the Self-Interaction Dark Matter(SIDM) model. Since the mean free path of real CDM particle systems is much longer than that in the simulations, our results imply 1) that there is probably no 'cusp problem' in real CDM halos, and 2) that a much longer time is needed to form new virialized halos in real CDM particle systems than in the simulations. This last result can help us understand the 'substructure problem'. Our discussion can also explain why the massive halos in the simulations may have smaller concentration coefficients.

description: Der anhaltende Strukturwandel vergrößert die Unterschiede zwischen zentrumsnah und -fern gelegenen Regionen. Zur Bewältigung ihrer vielfältigen Problemlagen suchen strukturschwache ländliche Räume häufig ihren Ausweg im Tourismus. Die Auffassung des Fremdenverkehrs als 'letzter Rettungsanker' ist jedoch gerade in diesen Gebieten nicht unumstritten. Die vorliegende Arbeit befasst sich daher mit der Frage, inwieweit und unter welchen Umständen der Fremdenverkehr Entwicklungsimpulse in strukturschwachen ländlichen Regionen einleiten kann. Am Beispiel der Leader-Region Mühlviertler Alm wird gezeigt, dass der Tourismus, entgegen der in ihn gesetzten Hoffnungen, keine nennenswerten Einflüsse auf die wirtschaftliche Entwicklung nehmen kann. Der ländliche Tourismus wirkt sich vielmehr über indirekte Effekte positiv auf strukturschwache Räume aus. Als Bestandteil einer ganzheitlich orientierten Regionalpolitik ist der Tourismus in der Lage, Impulse zur Stärkung des sozialen Zusammenhalts und der raumbezogenen Identität zu setzen.
description: The ongoing structural changes increase the disparities between central and peripheral regions. To overcome their multifaceted problems economically underdeveloped rural areas frequently set their hope on tourism. However, the perception of tourism as 'last resort' is particularly in structurally weak regions not without controversy. This thesis addresses the question, how far and under what circumstances tourism could trigger local development impulses in economically underdeveloped rural areas. Based on the example of Leader-Region Mühlviertler Alm the present paper depicts that tourism, contrary to expectations, scarcely influences the economic development in structurally weak regions. Tourism rather exerts positive impacts on rural areas indirectly. As part of an integrated regional policy tourism enables remote destinations to strengthen both social cohesion and local identity.

description: From the SU(2) spin chain sigma model at the one-loop and two-loop orders we recover the classical circular string solution with two S^5 spins (J_1, J_2) in the AdS_5 x S^5 string theory. In the SL(2) sector of the one-loop spin chain sigma model we explicitly construct a solution which corresponds to the folded string solution with one AdS_5 spin S and one S^5 spin J. In the one-loop general sigma model we demonstrate that there exists a solution which reproduces the energy of the circular constant-radii string solution with three spins (S_1, S_2, J).

description: Grundsätzliche Intention der vorliegenden Arbeit war es, Möglichkeiten der Bewertung für eine individuelle Baulandeignung auf einem mobilen Endgerät vor Ort zu beleuchten. Ausgehend von einem kurzen Überblick über die Entwicklung des Mobilfunks sowie der Positionierungsmöglichkeiten im Rahmen von Location Based Services wurden die Grundlagen von Geographischen Informationssystemen erläutert. Nach einer kurzen Einführung in die Grundlagen der Raumplanung im Land Niederösterreich wurde sodann ein Konzept erarbeitet, mit dem einerseits die Darstellung der Eignung von Flächen als potentielles Bauland möglich sein sollte sowie andererseits die Möglichkeit geboten werden sollte, eine individuelle Bewertung der Eignung von bestehenden Baulandreserven nach bestimmten, persönlich gewichteten Parametern vorzunehmen. Die dabei auftretenden, unterschiedlichen Ausgangsvoraussetzungen, wurden anhand dreier unterschiedlicher Gemeinden in Niederösterreich gezeigt. Dieser Einsatz möglicher Parameter im Rahmen einer individuellen Bewertung wurde anhand eines Beispiels in der Stadtgemeinde Bad Vöslau mittels exemplarischer Eingangsdaten gezeigt. Darüber hinaus wurde beispielhaft unterschiedliches Nutzerverhalten beleuchtet und auf die Beispielgemeinden umgelegt.
description: The general aim of this thesis was to show the possibilities of a location based, individual assessment of building land on a mobile device. Starting with a general survey concerning the history of mobile communications and location techniques in location based services in a next chapter some basics of Geographic Information Systems were characterized. After a short abstract of the regional planning in Lower Austria a concept was developed that should provide mainly two things - on the one hand it should be possible to show the usability of areas to become building land. Otherwise, the user should be able to perform an assessment of building land and real estate, based on chosen and individually weighted parameters. To show the different basic requirements an example was given comparing some parameters of three communities in Lower Austria. The application of parameters in the context of an individual assessment was shown in an example based on an area in Bad Vöslau, using a selection of input data.

description: Negli ultimi due anni l'espansione di intermediazione bancaria in Italia ha subito una battuta d'arresto . La riduzione della quota di ricchezza finanziaria dell'economia rappresentata dai depositi bancari e il rapporto tra depositi bancari e il prodotto interno lordo ha scatenato un vivace dibattito , in particolare nel sistema bancario . Tuttavia , finora non ci sono state analisi sistematiche delle cause di questo fenomeno . Il presente lavoro prende in esame la recente " disintermediazione " bancaria utilizzando gli strumenti analitici di economia monetaria. Un'analisi econometrica di una funzione di domanda per i depositi bancari offre una "spiegazione " del perchè loro tasso di crescita è diminuito e permette di quantificare i fattori causali . Inoltre , è possibile simulare questo modello per ricavare implicazioni in termini di tendenze future . Over the past two years the expansion of banking intermediation in Italy has come to a halt. The reduction in the share of financial wealth of the economy represented by bank deposits and in the ratio of bank deposits to gross domestic product has sparked a lively debate, particularly in the banking system. However, thus far there have been no systematic analyses of the causes of this phenomenon. The present work examines the recent banking "disintermediation" using the analytical tools of monetary economics. An econometric analysis of a demand function for bank deposits offers an "explanation" of their decreased growth rate and allows to quantify the causal factors. Moreover, it is possible to simulate this model to derive implications in terms of expected future trends. JEL: E41, E52, G21

description: Il lavoro prevede che l'indebitamento internazionale, così come il governo nazionale e l'indebitamento delle imprese , tendono a degenerare , e poi diventano auto-alimentatw , quando gli interessi non possono essere pagati dal rendimento sul capitale investito , ma sono pagati da nuovi finanziamenti . Inoltre , una tale degenerazione può essere tanto maggiore quando l'intermediazione bancaria è in impieghi a medio e lungo termine e quanto più pienamente il sistema bancario è integrato . L'autore conclude che l'esito di questo processo deve essere l'inflazione , che non può essere superato attraverso alti tassi di interesse in quanto si nutrono maggiore indebitamento .. The work establishes that international indebtedness, as well as domestic government and corporate indebtedness, tend to degenerate, and then become self-feeding, when interests cannot be paid out of the return on the capital employed but are paid out of new borrowings. Furthermore, such a degeneration can be the farther extended, the greater the bank intermediation in medium and long term lending and the more fully the banking system is integrated. The author concludes that the outcome of this process must be inflation, which cannot be overcome through high interest rates since they feed higher indebtedness. JEL: F34, E31, E43

description: Fourteen promising papaya (Carica papaya L.) varieties were identified in a germplasm characterization study established at the Lajas Experiment Station on 7 April 1993. The large fruited (> 2 kg) processing type cultivars 'Villalba', 'Giant Panama Eet' and 'Cartagena' had higher yields than the traditional commercial cultivar 'Puerto Rico 6-65'. 'Yuen Nong No. 1', Tainung No. 5', 'Khag Naun' and 'Solo 40' have elongated fruits of medium size (1-2 kg), and are well suited for production of immature or mature fruit for local consumption and/or export to Latin/Asian markets. Yield of solo type 'Rafael' was not significantly different from that of the commercial 'Sunrise' cultivar, but hermaphroditic plants of 'Rafael' had 99.3% marketable fruit compared to only 78% for 'Sunrise' due to a high frequency of carpellody. Papaya cultivars identified as desirable for home gardens and/or specialty markets include 'Paco', 'Washington 5', 'Cariflora', 'Honey Gold', 'Puerto Rico 6-65 Dwarf' and chlorophyll mutant HCAR 185.
Theory of anisotropic s-wave superconductivity with point-node like gap minima: analysis of (Y,Lu)Ni_2B_2C

description: Recent intensive experimental studies revealed that (Y,Lu)Ni$_2$B$_2$C is an anisotropic s-wave superconductor. In addition, its gap function possesses deep point minima, whose ratio of the gap anisotropy is more than 10. On the theoretical side, however, it is nontrivial to understand the origin of such a peculiar superconductivity. In the present paper, we propose a mechanism of the s-wave superconductivity with deep gap minima, based on the theoretical model where strong electron-phonon coupling as well as the moderate magnetic fluctuations coexist. By analyzing the strong coupling Eliashberg equation, we find that s-wave superconducting gap function owing to the electron-phonon coupling becomes highly anisotropic as the magnetic fluctuations increases. The set of model parameters for realizing the strong gap anisotropy in the present model will be appropriate for (Y,Lu)Ni$_2$B$_2$C. According to the present mechanism, (groups of) pair of gap minima appear at points on the Fermi surface which are connected by the nesting vector ${\bf Q}$, in both cases of s-wave superconductors and non s-wave ones. We briefly discuss other superconductors with highly anisotropic gap function, e.g., PrOs$_{4}$Sb$_{12}$ and Na$_{0.33}$CoO$_2$.

description: Papaya seeds from four open pollinated papayas varieties 'Cariflora', 'Puerto Rico 6-65', 'Solo- 64' and 'Waimanalo 162' were soaked for 5 days in water or -1 MPa solutions of CaCl2, Ca(N03)2, K.C1 or KNOs. Following priming, treated seeds were rinsed and air dried for two days prior to planting. Untreated seeds were planted as controls. Seedling emergence was recorded daily. Priming reduced the mean time for seedling emergence for all salt treatments. The KNO, treatment resulted in the greatest seedling emergence in the shortest length of time. Pretreating papaya seeds with a salt solution can be used to enhance seed germination and plant emergence in a shorter length of time than untreated seed.

description: The landscape of string/M theory is surveyed over a large class of type $IIB$ flux compactification vacua. We derive a simple formula for the average size of the gauge group rank on the landscape under assumptions that we clearly state. We also compute the rank under the restriction of small cosmological constant, and find a slight increase. We discuss how this calculation could impact proton stability by computing the suppression factor for the number of vacua with additional gauge group rank that could be used to protect the proton. Finally, we present our views on the utility and limitations of landscape averages, especially in the context of this analysis.

description: The LHCb Collaboration, using its full data set from runs $1$ and $2$, announced in $2019$ a surprising update of the hidden-charm pentaquark states $P_c(4380)^+$ and $P_c(4450)^+$, observed in 2015. A new state, $P_c(4312)^+$, was clearly seen at lower energies; furthermore, the original $P_c(4450)$ resonance was resolved into two individual states, named the $P_c(4440)^+$ and the $P_c(4457)^+$. Motivated by the fact that these new hidden-charm pentaquark states were successfully predicted by our chiral quark model, we extend herein such study to the doubly charmed sector. The analyzed total spin and parity quantum numbers are $J^P=\frac12^-$, $\frac32^-$ and $\frac52^-$, in the $I=\frac12$ and $\frac32$ isospin channels. We find several possible narrow baryon-meson resonances (theoretical masses in parenthesis): $IJ^P = \frac12 \frac12^-$ $Σ_c D(4356)$, $\frac12 \frac32^-$ $Σ^*_c D(4449)$, $\frac32 \frac12^-$ $Σ_c D(4431)$, $\frac32 \frac12^-$ $Σ_c D(4446)$, $\frac32 \frac32^-$ $Σ_c D^*(4514)$ and $\frac32 \frac52^-$ $Ξ^*_{cc} ρ(4461)$ whose widths are $4.8$, $8.0$, $2.6$, $2.2$, $4.0$ and $3.0\,\text{MeV}$, respectively. Moreover, one shallow bound-state is found, too, with quantum numbers $IJ^P = \frac12 \frac32^-$ $Ξ^*_{cc} π(3757)$. These doubly charmed pentaquark states are expected to be identified in future experiments.

Pathogenesis of neurofibromatosis 1 associated neurofibromas
Creators: name: Tucker, Tracy
Publisher: name: University of British Columbia
Year: 2011

description: Neurofibromatosis 1 (NF1) is an autosomal dominant disease. Neurofibromas, benign tumours that develop from peripheral nerves, are a hallmark feature of NF1. Malignant peripheral nerve sheath tumours (MPNSTs) are one of the leading causes of death in people with NF1. Clinical evidence suggests that most MPNSTs develop from pre-existing plexiform neurofibromas. Most studies treat all NF1-associated neurofibromas as a single entity, ignoring important differences between pathological details, clinical presentation and natural history. I analysed clinical information on 476 probands with NF1 from the Henri Mondor database and found that individuals with subcutaneous neurofibromas were 3 times more likely to have internal plexiform neurofibromas and that individuals with internal plexiform neurofibromas were 20 times more likely to have MPNSTs than individuals without such tumours. These findings suggest that pathogenic differences in some neurofibromas may lead to different risks of progressing to malignancy. I collected formalin-fixed paraffin-embedded samples from NF1 patients and classified them histologically as nodular or diffuse neurofibromas. By using histochemistry, I found that mast cells were absent in MPNSTs and significantly more abundant in diffuse neurofibromas than in nodular neurofibromas. Mast cells were located at the periphery of nodular neurofibromas but were evenly distributed throughout diffuse neurofibromas. Double immunofluorescent staining of S100 (a marker of Schwann cells, the presumed tumour progenitor cell type) and neurofibromin (the protein product of NF1 gene) (Nf) showed that diffuse neurofibromas had significantly more S100+/Nf+ cells and fewer S100-/Nf- cells than nodular neurofibromas. Using laser microdissection of immunofluorescently stained slides, I found that some neurofibromas show evidence of clonal (presumably neoplastic) proliferation of S100+/Nf- cells while other neurofibromas appear to be neurofibromin haploinsufficient and polyclonal, and thus may be hyperplastic rather than neoplastic lesions. The results presented in this thesis support the hypothesis that neurofibromas in people with NF1 are pathogenically heterogeneous and that some kinds of neurofibromas are associated with the development of MPNSTs. These findings have important implications for the surveillance and treatment of people with NF1.

description: This work is about the feasibility of using slender elements combined with pneumatic chambers as support structural elements in temporary membrane structures applications. Spline term in this work refers to those straight and slender elements that are bent to form a continuous spatial curve and identical moment of inertia (second moment of area) about any axis perpendicular to its centroidal axis. It is common to use arches as supporting elements in membrane lightweight structures. There are very few applications of spline elements combined with membranes in medium - large span structures. Applications in small spans are more common for example in camping tent systems where spline elements are stiff enough to take external forces. For medium (16 - 32 m) span structures it is common that spline elements need in-plane bracing systems formed by masts and cables, in order to increase stiffness and strength properties to be able to bare real external forces (wind or snow). It is included the use of pneumatic chambers instead of mast-cables system in order to make spline arches stiff enough to withstand real external forces. Analytical models whereas realistic load conditions were developed using specialized software (EASY, RSTAB). Several configurations of size and position of pneumatic chambers were evaluated. Different materials and their properties were also analyzed to be adequate for spline element requirements. Additional vertical truss elements and cables were required to stabilize the hybrid arch. As a result of this work, it is demonstrated analytically that it is possible to use pneumatic chambers and additional vertical truss elements and cables to give enough stiffness to spline slender arches under real loading conditions. A basic detailing proposal for connections and erection process is presented.
'Nothing is ours anymore' – HLP rights violations in Afrin, Syria

Subjects: subject: 180114 Human Rights Law
subject: FOS: Law

description: This chapter presents a case study of the housing, land and property (HLP) situation for local and displaced persons in the Syrian region of Afrin since the Turkish-led ‘Operation Olive Branch’ was launched in January 2018. HLP rights violations are described in interviews that provide nuanced accounts of the roles and engagement of different actors in relation to the occupation and transfer of housing, land and property. This study specifically considers the involvement of the Turkish Armed Forces, their Syrian partners (the Free Syrian Army, FSA, and other factions), as well as internally displaced persons (IDPs) resettled from elsewhere in Syria. The dynamics between these actors, as well as the local councils and civil police forces set up by Turkey and its Syrian allies, are analysed so as to understand the complexities of who is committing, and ultimately accountable for, HLP violations in Afrin.

The overlapping HLP issues in today’s Syria are exemplified by the relocation to Afrin of displaced families, particularly those evacuated from the rural areas around Damascus that were returned to Syrian government control in spring 2018. Framed in the larger context, the Afrin case study presents compelling testimony of the many ways the Syrian conflict has impacted enjoyment of HLP rights. This chapter documents various HLP violations committed against individuals from Afrin during and since the military operation and accepts as credible local interviewees’ claims that the violations are politically motivated attempts to change the demographics of a historically Kurdish region. Recent practices of HLP transfers in Afrin mirror policies enacted by the Turkish government against its own Kurdish population and build on pre-conflict measures introduced by the Syrian authorities to restrict property and housing ownership in targeted border areas.

description: The Kondo effect has been playing an important role in strongly correlated electon systems. The important point is that the magnetic impurity in metals is a typical example of the Fermi liquid. In the system the local spin is conserved in the ground state and continuity with respect to Coulomb repulsion $U$ is satisfied. This nature is satisfied also in the periodic systems as far as the systems remain as the Fermi liquid. This property of the Fermi liquid is essential to understand the cuprate high-Tc superconductors (HTSC). On the basis of the Fermi liquid theory we develop the transport theory such as the resistivity and the Hall coefficient in strongly correlated electron systems, such as HTSC, organic metals and heavy Fermion systems. The significant role of the vertex corrections for total charge- and heat-currents on the transport phenomena is explained. By taking the effect of the current vertex corrections into account, various typical non-Fermi-liquid-like transport phenomena in systems with strong magnetic and/or superconducting flucutations are explained within the Fermi liquid theory.

description: We explore the consequences of periodically modulating a quantum two-level system (TLS) with an asymmetric pulse when the system is in contact with thermal baths. By adopting the Floquet-Lindblad formalism for our analysis, we find that the unequal "up" and "down" time duration of the pulse has two main ramifications. First, the energy gap of the multiple sidebands or photon sectors created as a result of the periodic modulation are renormalized by a term which is dependent on both the modulation strength as well as the fraction of up (or down) time duration. Second, the weights of the different sidebands are no longer symmetrically distributed about the central band or zero photon sector. We illustrate the advantages of these findings in the context of applications in quantum thermal machines and thermometry. For a thermal machine constructed by coupling the TLS to two thermal baths, we demonstrate that the asymmetric pulse provides an extra degree of control over the mode of operation of the thermal machine. Further, by appropriately tuning the weight of the subbands, we also show that an asymmetric pulse may provide superior optimality in a recently proposed protocol for quantum thermometry, where dynamical control has been shown to enhance the precision of measurement.

L' articolo descrive il dibattito e delle riforme del secondo tipo di pensioni pubbliche . L'impatto di un recente referendum sui bilanci delle imprese italiane , derivante da una variazione deicontributi per i datori di lavoro , inoltre sono discusse ulteriori riforme. The Italian system is characterized by an old-age pension that accrues to individuals above a certain age, and a seniority pension, the eligibility of which is related to previous employment experience. The article describes the debate and reforms of the latter kind of public pensions. The impact of a recent referendum on Italian firms’ balance sheets, arising from a change in employers’ contributions, as well as the directions for further reform are discussed. JEL: H55

description: Finora , le spiegazioni e le interpretazioni della crescita del settore dei servizi e deindustrializzazione sembrano essere controverse e parzialmente insoddisfacenti. A differenza di studi precedenti , il presente lavoro affronta le due questioni insieme . Secondo l'ipotesi dell'autore , la crescita del servizio di occupazione del settore è dovuto al crescente grado di integrazione di servizi nel sistema produttivo e nel settore industriale . Una metodologia particolare , si propone di verificare questa ipotesi . Viene quindi applicato al caso di espansione terziario in Italia .So far, the explanations and interpretations of the growth of the service sector and deindustrialization seem to be controversial and partially unsatisfactory. Unlike previous studies, the present work deals with the two issues together. According to the author’s hypothesis, the growth in service sector employment is due to and increasing degree of integration of services in the productive system and in industry. A particular methodology is proposed to test this hypothesis. It is then applied to the case of service sector expansion in Italy. JEL: O14

description: Die Arbeit befasst sich mit der Frage, wie Schülerinnen und Schüler mit sonderpädagogischer Unterstützung in integrativen Regelklassen den Unterricht im Allgemeinen und die unterschiedlichen Formen der Förderung im Speziellen erleben. Angelehnt an die Studie D5 „Die Qualität des Erlebens von Lernenden in integrativen und separativen Schulformen“ (Venetz, Tarnutzer, Zurbriggen & Sempert, 2010) liegt bei dieser Arbeit der Fokus auf der Erlebensqualität in den unterschiedlichen Förderungsformen. Dazu wurden die mit der Experience Sampling Method ESM und Fragebogen erfassten Daten zur allgemeinen Befindlichkeit und zum aktuellen Erleben im Unterricht ausgewertet. Die Ergebnisse zu den drei Formen der Förderung sind nicht eindeutig und lassen sich nur schwer interpretieren. Einzelne Befunde bestätigen jedoch die Prinzipien und Methoden des integrativen Unterrichts.

Das Endprodukt ist der Entwurf eines Hotels in Banja Luka.Internationale Empfehlungen, Normen und Gesetze dienten als Ausgangspunkte und Grundlagen für die Definierung der Inhalte und Einrichtung des jeweiligen Gebäudes. Neben der Analyse der einschlägigen Unterlagen über die Barrierefreiheit, wurde auch der Tourismussektor in Bosnien und Herzegowina untersucht, auf regionaler sowie lokaler Ebene. Die festgestellten Potenziale und Mängel leiteten die Entwicklung des Konzepts. Das Ziel war ein barrierefreies Objekt zu gestalten das dass Bewusstsein über Inklusion fördert, das neben den Maßnahmen im Design, auch architektonische Mittel benutzt.
description: The present work deals with the issue of accessibility in architectural context. The final product is the design of a hotel in Banja Luka. International recommendations, standards and laws served as starting points and bases for the definition of the content and arrangement of the building itself. In addition to the analysis of relevant documents concerning the accessibility, the tourism sector in Bosnia and Herzegovina was examined at regional as well as at local level. The identified potentials and deficiencies directed the development of the concept. The goal was to configure an accessible object which will raise the awareness of inclusion, which also uses architectural methods in addition to the design.

description: Influence Maximization (IM) aims at finding the most influential users in a social network, i. e., users who maximize the spread of an opinion within a certain propagation model. Previous work investigated the correlation between influence spread and nodal centrality measures to bypass more expensive IM simulations. The results were promising but incomplete, since these studies investigated the performance (i. e., the ability to identify influential users) of centrality measures only in restricted settings, e. g., in undirected/unweighted networks and/or within a propagation model less common for IM. In this paper, we first show that good results within the Susceptible- Infected-Removed (SIR) propagation model for unweighted and undirected networks do not necessarily transfer to directed or weighted networks under the popular Independent Cascade (IC) propagation model. Then, we identify a set of centrality measures with good performance for weighted and directed networks within the IC model. Our main contribution is a new way to combine the centrality measures in a closed formula to yield even better results. Additionally, we also extend gravitational centrality (GC) with the proposed combined centrality measures. Our experiments on 50 real-world data sets show that our proposed centrality measures outperform well-known centrality measures and the state-of-the art GC measure significantly. social networks, influence maximization, centrality measures, IC propagation model, influential spreaders
Galvanic interaction between chalcopyrite and pyrite during atmospheric leaching
Creators: name: Mayne, Darren Douglas
Publisher: name: University of British Columbia
Year: 2011

description: Chalcopyrite is the most abundant copper minerals, yet one of most difficult to leach due to a passive layer which forms under a variety of oxidative leaching conditions. For this reason, chalcopyrite has traditionally been processed by pyrometallurgical routes. However, due to a host of environmental and economic issues there has been increased interest in developing a hydrometallurgical process to treat primary copper sulfides. A novel process was developed at UBC in which pyrite was added intentionally to chalcopyrite to provide a galvanically-assisted leach. The ground minerals were subjected to an acidified ferric sulfate solution at atmospheric pressure, and excellent copper recovery was achieved. The present study continued this work, applying the technology to several chalcopyrite concentrates in order to determine optimal conditions for the leach. Leaching experiments were conducted in a sealed 3-liter jacketed glass stirred-tank reactor. Initial work with a concentrate from Zambia was conducted using pyrite from the Huanzala region of Peru. It was determined that a pyrite-to-chalcopyrite ratio of 2.7 was optimal. The solution potential should be controlled above 455 mV vs Ag/AgCI, although it is difficult to comment on the optimal range due to gas liquid mixing limitations at higher potentials. Initial acid content of 1.8 kg per kg concentrate and a leach temperature of 80°C were also selected for best results. Pyrite remained an effective catalyst when recycled wet as very little was oxidized during the leach. A second chalcopyrite concentrate from Mongolia was obtained, along with a pyrite concentrate from the same mine. The optimal conditions from the previous study were used. Initial experiments showed a significant induction period, but the induction period deceased substantially when a second charge of concentrate was used with the wet-recycled residue. It was believed that reagents used in the flotation circuit may have fouled the surface of the pyrite, thus reducing its effectiveness as a galvanic catalyst. Attempts were made to 'activate' the pyrite concentrate prior to use, but these proved unsuccessful. It remains unclear why the pyrite becomes more reactive when recycled.
