description: The hydrogenated silicon nitride layers (SiNx:H) serve as passivation layers in Si solar cells. After deposition, the cells undergo a rapid thermal annealing process (RTA). The high temperature activates the stored hydrogen in SiNx:H to further passivate defects in Si. The mechanism of hydrogen passivation and its relation to the material structure is not yet fully understood. Therefore, in this study, the following objectives are investigated. A simplified effusion measurement setup was developed to measure hydrogen with high sensitivity. The structural analysis of SiNx:H was investigated and discussed. A systematic analysis is performed focusing on the influence of layer properties on hydrogen effusion/diffusion mechanisms at high temperatures. As a conclusion, a model is proposed to describe the hydrogen behaviour

Die hohe Temperatur aktiviert den vorhandenen Wasserstoff, um Defekte in Si weiter zu passivieren. Der Mechanismus der Wasserstoffpassivierung und sein Zusammenhang mit der Materialstruktur noch nicht vollständig geklärt. In dieser Studie werden die folgenden Ziele untersucht. Ein vereinfachter Effusionsmessaufbau wurde entwickelt, um Wasserstoff mit hoher Empfindlichkeit zu messen. Die Strukturanalyse von SiNx:H wurde untersucht und diskutiert. Es wird eine systematische Analyse durchgeführt, die sich auf den Einfluss der Schichteigenschaften auf die Wasserstoff Effusions/Diffusionsmechanismen bei hohen Temperaturen konzentriert. Als Schlussfolgerung wird ein Modell zur Beschreibung des Wasserstoffverhaltens vorgeschlagen.

description: The APOS (Advanced Power Subassemblies project addresses the devices (MMIC or discrete) used in the solid state power amplifiers (SSPA) that drive the transmit active antenna. These are key devices and their electrical and thermal performances have a major impact on both the satellite and the ground terminals. GaAs-based heterostructure bipolar transistor, due to their superior power/linearity performance, could be one of these enabling devices. This aspect will be addressed within the frame of this project through three main objectives :
1)To  analyse  the   reliability  of  UMS  HBT technology  and   demonstrate   it   meets  the
requirements of the commercial satellite markets.
2)To improve the power and thermal performances of HBT by developing a power flip-
chip assembly technology using thermal bumps in the active area of the power device.
3)To benchmark the developed power HBT technology by using the power MMIC in a suitable active antenna module.
   This project consortium is formed by Alcatel Space, that will co-ordinate the project, United Monolithic Semiconductors (UMS), Thomson-CSF, Institute for Material Research at Limburg University Centrum (1MO-LUC), DESTIN and Institut d'Electronique et de Microelectronique du Nord (1EMN).

Year: 2023
Subjects: subject: 610

description: Area-based socioeconomic deprivation is a significant health indicator and can influence cancer survival rates. This thesis investigates survival disparities among endometrial (EC) and head and neck cancer (HNC) patients in Germany, utilizing the German Index of Socioeconomic Deprivation (GISD). An analysis of 42,423 EC and HNC patients revealed a decline in five-year survival as deprivation increased. Notably, Stage I EC patients in deprived regions faced higher mortality. For HNC patients, the impact of deprivation on survival was predominantly linked to the stage at diagnosis within the first six months. Previous studies in Germany have shown that higher rates of obesity, smoking, and physical inactivity were linked to regions characterized by a high deprivation score. While acknowledging the data limitations of cancer registries, current efforts to reduce tobacco consumption and promote physical activity should be supported, in addition to continued socioeconomic reform.
description: Gebietsbezogene sozioökonomische Benachteiligung ist ein wichtiger Gesundheitsindikator und kann die Krebsüberlebensraten beeinflussen. Diese Arbeit untersucht Überlebensunterschiede bei Endometriumkarzinom (EC) und Kopf-Hals-Krebs (HNC) Patienten in Deutschland unter Verwendung des German Index of Socioeconomic Deprivation (GISD). Eine Analyse von 42.423 EC und HNC Patienten zeigte einen Rückgang der Fünf-Jahres-Überlebensrate mit steigender Benachteiligung. Insbesondere EC-Patienten im Stadium I in benachteiligten Gebieten hatten eine höhere Sterblichkeit. Bei HNC-Patienten war der Einfluss der Benachteiligung hauptsächlich mit dem Diagnosestadium in den ersten sechs Monaten verknüpft. Deutsche Forschung verbindet höhere Benachteiligung mit Fettleibigkeit, Rauchen und Inaktivität. Es ist entscheidend, Anstrengungen zur Risikominderung und sozioökonomische Reformen zu verstärken.
Constitutional Patriotism as Europe's Public Philosophy? On the Responsiveness of Post-National Law
Creators: name: Linden-Retek, Paul
Publisher: name: Zenodo
Year: 2021

description: This paper scrutinizes Jürgen Habermas’s concept of constitutional patriotism—and its basis in his discourse theory of democracy and law—as the substance of a European public philosophy. Drawing on critical theorists’ reception of the concept and Habermas’s own contemporary writings on Europe’s crisis, I reconstruct constitutional patriotism from the analytic perspective of ‘constitutional imaginaries’. A constitutional imaginary emphasizes the relation of law to the broader societal and political meanings that create and interpret it from outside formal legal institutions. This perspective ‘thickens’ our understanding of the meaning of law as an object of public commitment, as well as of the processes through which this meaning changes (constitutional politics). The paper then details the consequences of this shift for the work of the contemporary European judiciary and its constitutional discourse. In the first instance, analysis of constitutional imaginaries reveals the extent to which civic attachment to constitutional law is oriented not merely to a legal principle simpliciter but also to the historical settlement of political conflict the principle reflects. This suggests that the plurality of constitutional imaginaries in the European legal space creates additional difficulties for inspiring civic attachments post-nationally, a problem to which European judiciaries have heretofore been unresponsive. Second, an understanding of Habermas’s work in light of constitutional imaginaries opens new avenues for rethinking the interpretive and structural tasks to which Europe’s juridical institutions should be directed. In particular, the chapter highlights new forms of proceduralism to be recovered in constitutional discourse in order to establish a reflexivity of constitutional imagination adequate to post-national politics.

description: This paper describes the development of a millimetre-wave front-end for a 76.5GHz Collision Warning Avoidance (CW/A) car radar. This CW/A sensor is based on a FMCW concept. The main development steps are described and have led to the definition of a fully MMIC-based front-end. Based on a demonstrator done in AWARE a new chip-set has been defined, fabricated and characterised within LOCOMOTIVE. Using a total chip-set area of 13.7 mm2, the first obtained results show a high level of performance.
MIMO backscatter RFID systems : performance analysis, design and comparison
Creators: name: He, Chen
Publisher: name: University of British Columbia
Year: 2014

description: Backscatter RFID systems are the most popular RFID systems deployed due to low cost and low complexity. However, they pose many design challenges due to their querying-fading-signaling-fading structure, which experiences deeper fading than conventional one-way channels. Recently, by simulations and measurements, researchers found that the MIMO setting can improve the performance of backscatter RFID systems. These simulations and measurements were based on simple signaling schemes and no rigorous mathematical analysis has been provided. In this thesis, we explore querying, STC, and diversity combining schemes over the three ends of the backscatter RFID systems and provide generalized performance analysis and design criteria. At the tag end, we show that the identical signaling scheme, which cannot improve the BER performance in conventional one-way channels, can significantly improve the BER performance of backscatter RFID. We also analytically study the performances of orthogonal STCs, with different sub-channel fading assumptions, and show that the diversity order depends only on the number of tag antennas. More interestingly, we show that the performance is more sensitive to the channel condition of the forward link than that of the backscattering link. In previous literature, the understanding of the query end is that the designs of query signals have no potential to improve the system performance. However, we show that some well-designed query signals can improve the system performance significantly. We propose a novel unitary query method in this thesis. Conventional measures of the physical layer performance cannot be obtained analytically in backscatter RFID channels with employing our unitary query. We thus provide a new performance measure to overcome the difficulty of conventional measures, and show that why the unitary query has superior performance. The multi-keyhole channel is another type of cascaded channel. The backscatter RFID channel and the multi-keyhole channels look similar, but are essentially different and there difference has not been clearly studied in previous literature. In the final part of this thesis, by investigating general STCs and revealing a few interesting properties of this channel in the MISO case, we show that the two channels achieves completely different diversity order and BER performance.

description: We revisit the Dynkin game problem in a general framework, improve classical results and relax some assumptions. The criterion is expressed in terms of families of random variables indexed by stopping times. We construct two nonnegative supermartingales families $J$ and $J'$ whose finitness is equivalent to the Mokobodski's condition. Under some weak right-regularity assumption, the game is shown to be fair and $J-J'$ is shown to be the common value function. Existence of saddle points is derived under some weak additional assumptions. All the results are written in terms of random variables and are proven by using only classical results of probability theory.

description: In sparse Bayesian learning (SBL), Gaussian scale mixtures (GSMs) have been used to model sparsity-inducing priors that realize a class of concave penalty functions for the regression task in real-valued signal models. Motivated by the relative scarcity of formal tools for SBL in complex-valued models, this paper proposes a GSM model - the Bessel K model - that induces concave penalty functions for the estimation of complex sparse signals. The properties of the Bessel K model are analyzed when it is applied to Type I and Type II estimation. This analysis reveals that, by tuning the parameters of the mixing pdf different penalty functions are invoked depending on the estimation type used, the value of the noise variance, and whether real or complex signals are estimated. Using the Bessel K model, we derive a sparse estimator based on a modification of the expectation-maximization algorithm formulated for Type II estimation. The estimator includes as a special instance the algorithms proposed by Tipping and Faul [1] and by Babacan et al. [2]. Numerical results show the superiority of the proposed estimator over these state-of-the-art estimators in terms of convergence speed, sparseness, reconstruction error, and robustness in low and medium signal-to-noise ratio regimes.

description: We investigate the LHC signals of a minimal supersymmetric hidden valley. Our theory consists of the supersymmetric Standard Model along with a light hidden U(1)_x gauge multiplet and a pair of hidden chiral superfields that spontaneously break the new Abelian gauge symmetry near a GeV. The visible and hidden sectors interact exclusively through supersymmetric gauge kinetic mixing. We perform a thorough examination of the hidden decay cascades initiated by the lightest Standard Model superpartner and we study the range of LHC signals they can produce. In particular, we find parameter regions that give rise to missing energy, single and multiple lepton jets, and displaced vertices. Given the simplicity of the underlying theory and the broad range of collider signals it can produce, we propose that this model is a useful benchmark for LHC studies of (supersymmetric) hidden valleys.

description: We show that under certain technical assumptions, including the existence of a constant mean curvature (CMC) slice and strict positivity of the scalar field, general relativity conformally coupled to a scalar field can be quantised on a partially reduced phase space, meaning reduced only with respect to the Hamiltonian constraint and a proper gauge fixing. More precisely, we introduce, in close analogy to shape dynamics, the generator of a local conformal transformation acting on both, the metric and the scalar field, which coincides with the CMC gauge condition. A new metric, which is invariant under this transformation, is constructed and used to define connection variables which can be quantised by standard loop quantum gravity methods. While it is hard to address dynamical problems in this framework (due to the complicated 'time' function), it seems, due to good accessibility properties of the CMC gauge, to be well suited for problems such as the computation of black hole entropy, where actual physical states can be counted and the dynamics is only of indirect importance. The corresponding calculation yields the surprising result that the usual prescription of fixing the Barbero-Immirzi parameter beta to a constant value in order to obtain the well-known formula S = a(Phi) A/(4G) does not work for the black holes under consideration, while a recently proposed prescription involving an analytic continuation of beta to the case of a self-dual space-time connection yields the correct result. Also, the interpretation of the geometric operators gets an interesting twist, which exemplifies the deep relationship between observables and the choice of a time function and has consequences for loop quantum cosmology.

description: Das Antwortverhalten von gleitgelagerten Rotoren ist nicht nur von den hochgradig nichtlinearen Eigenschaften der Radiallager abhängig, sondern auch vom Axiallager. Je nach Design, Anordnung und Ausführung des Axialgleitlagers kann Einfluss auf das Rotorsystem genommen werden. In dieser Arbeit wird zur Ermittlung der hydrodynamischen Zustände in Gleitlagern die Reynolds-Differentialgleichung mit masseerhaltender Kavitation nach dem Zwei- Phasenmodell ausgewertet. Dies erfolgt sowohl für den radialen als auch axialen Schmierspalt. Für gekoppelte Ölfilme wird eine Implementierung der Reynolds-Gleichung vorgestellt, wodurch der Schmiermittelaustausch im Übergangsbereich berücksichtigt wird. Zum Abgleich der entwickelten Routinen werden Ergebnisse aus der Literatur und Wellenbewegungsmessungen von Rotoren herangezogen. Um ein breites Anwendungsspektrum abzudecken, weisen die Rotoren unterschiedliche strukturdynamische Eigenschaften und verschiedene Lagerungskonzepte auf. Ziel dieser Arbeit ist es, das rotordynamische Systemverhalten zu prädiktieren und in diesem Zusammenhang den Einfluss der Axiallagerung sowie die Zustände in den Lagern aufzuzeigen.
description: The rotor’s response behavior is not only depending on the highly nonlinear properties of the radial bearings, but also on the thrust bearing. According to the design, arrangement and construction concept of the thrust bearing, the rotor vibration mode can be influenced. In this thesis, the Reynolds differential equation with mass-conserving cavitation according to the two-phase model is evaluated to determine the pressure and lubricant distribution in hydrodynamic bearings. This is done for radial and thrust bearings as well as for combined bearing arrangements. For coupled oil films, an implementation of the Reynolds equation is presented, whereby the lubricant exchange is taken into account. To validate the developed routines, results from the literature and shaft motion measurements of rotors are used. In order to ensure that a wide range of applications is covered, rotors with different bearing concepts are investigated. As a result, various excitation causes can exist, which can lead to increased vibration amplitudes. The aim of this work is therefore to predict the rotordynamic system behavior and to show the influence of the thrust bearing and the conditions in the bearings.

We use the SL(2,R) symmetry to determine algebraically the purely imaginary quasinormal frequencies of the RN black hole. We confirm that these are exactly quasinormal modes of scalar perturbation around the near-extremal black hole.

Consider a $p$-adic group $G=GL(α+k\infty, Q_p)$, its subgroup $L=O(k\infty,Z_p)$, and the subgroup $K=O(\infty,Z_p)$ embedded to $L$ diagonally. We show that double cosets $Γ= K\setminus G/K$ admit a structure of a semigroup, $Γ$ acts naturally in $K$-fixed vectors of unitary representations of $G$. For each double coset we assign a 'characteristic function', which sends a certain Bruhat--Tits building to another building (buildings are finite-dimensional); image of the distinguished boundary is contained in the distinguished boundary. The latter building admits a structure of (Nazarov) semigroup, the product in $Γ$ corresponds to a point-wise product of characteristic functions.

description: Die Doktorarbeit gliedert sich in zwei große Bereiche. Der erste Teil befasst sich mit der Leistungsfähigkeit bzw. den Grenzen des konfokalen Raman-Mikroskops bezüglich der Spannungsmessungen. Für die quantitative Bestimmung der Spannung ist die Kenntnis einiger Geräteparameter notwendig. Dazu gehören zum Beispiel die Stabilität der Laserleistung, die Verschiebung des Silizium-Peaks durch thermische Einflüsse und die Laserleistung auf der Probe. Im zweiten Teil der Doktorarbeit werden die Einflüsse unterschiedlicher Probenpräparationsverfahren auf die mechanischen Spannungen im Silizium untersucht. Ziel war es, ein fertig aufgebautes elektronisches Bauteil so zu präparieren, dass der ursprüngliche Spannungszustand im darin enthaltenen Siliziumchip nur geringfügig beeinflusst wird. Zu allen Versuchen wurden Simulationen mit Hilfe des Finite-Elemente-Programms ANSYS durchgeführt, um die Plausibilität der Messungen und der daraus abgeleiteten Spannungswerte analytisch zu überprüfen.
description: The thesis is divided into two major topics. The first part deals with the performance respectively the limitations of the confocal Raman microscope regarding stress measurements. For the quantitative determination of the mechanical stress the knowledge of some device parameters are necessary. These includes for example the stability of the laser power, the shift of the silicon peak due to thermal effects and the laser power on the sample. In the second part of the thesis the influences of different sample preparation methods on the mechanical stresses in the silicon are investigated. The aim was to prepare a finished electronic component in such a way that the original stress state in the silicon chip is only slightly affected. Simulations were performed for all experiments using the finite element program ANSYS in order to analytically check the plausibility of the measurements and the stress values derived from them.

description: Diese Arbeit befasst sich mit langfaserverstärktem Polypropylen (PP-LGF), welches mittels Gasinjektionstechnik (GIT) im Fließpressprozess (GasComp-Prozess) und Spritzgussprozess (GAIM-Prozess) zu Hohlstrukturen verarbeitet wurde. Hierbei wurden pultrudiertes sowie ummanteltes Langglasfasergranulat betrachtet. Bei der GIT wurden das Short-Shot- und das Nebenkavitätsverfahren eingesetzt. Das Ziel der Arbeit war es die Leichtbaupotenziale von Bauteilen, die mit der GIT in Verbindung mit PP-LGF gefertigt werden, zu ermitteln und Anwendungsbereiche zu identifizieren. Hierzu wurden mechanische und mikrostrukturelle (u.a. CT, REM) Analysen durchgeführt um das Versagensverhalten, die Faserorientierung und –länge, die Porosität sowie die Grenzfläche von Polymer und Gasblase zu charakterisieren. Die Ergebnisse liefern nicht nur neue Erkenntnisse bei der Verarbeitung von Langfasergranulat mit GIT, sondern zeigen auch Leichtbaupotenziale für unterschiedliche Anwendungsbereiche auf.
description: This thesis deals with long fiber reinforced polypropylene (PP-LGF), which was processed into hollow structures using gas injection technology (GIT) in the compression molding process (GasComp process) and injection molding process (GAIM process). Here pultruded and coated long glass fiber granulate were considered. The short-shot and the secondary cavity method were used at GIT. The aim of the work was to determine the lightweight construction potential of components that are manufactured with GIT in connection with PP-LGF and to identify areas of application. For this purpose, mechanical and microstructural (e.g. CT, SEM) analyzes were carried out to characterize the failure behavior, the fiber orientation and length, the porosity and the interface between polymer and gas bubble. The results not only provide new insights into the processing of long fiber granulate with GIT, but also show lightweight construction potential for different areas of application.

description: Random beamforming (RBF) is a practically favourable transmission scheme for multiuser multi-antenna downlink systems since it requires only partial channel state information (CSI) at the transmitter. Under the conventional single-cell setup, RBF is known to achieve the optimal sum-capacity scaling law as the number of users goes to infinity, thanks to the multiuser diversity enabled transmission scheduling that virtually eliminates the intra-cell interference. In this paper, we extend the study of RBF to a more practical multi-cell downlink system with single-antenna receivers subject to the additional inter-cell interference (ICI). First, we consider the case of finite signal-to-noise ratio (SNR) at each receiver. We derive a closed-form expression of the achievable sum-rate with the multi-cell RBF, based upon which we show an asymptotic sum-rate scaling law as the number of users goes to infinity. Next, we consider the high-SNR regime and for tractable analysis assume that the number of users in each cell scales in a certain order with the per-cell SNR. Under this setup, we characterize the achievable degrees of freedom (DoF) for the single-cell case with RBF. Then we extend the analysis to the multi-cell RBF case by characterizing the DoF region. It is shown that the DoF region characterization provides useful guideline on how to design a cooperative multi-cell RBF system to achieve optimal throughput tradeoffs among different cells. Furthermore, our results reveal that the multi-cell RBF scheme achieves the "interference-free DoF" region upper bound for the multi-cell system, provided that the per-cell number of users has a sufficiently large scaling order with the SNR. Our result thus confirms the optimality of multi-cell RBF in this regime even without the complete CSI at the transmitter, as compared to other full-CSI requiring transmission schemes such as interference alignment.

Raccontare il mondo in lingue diverse: sarà lo stesso mondo?

Subjects: L-LIN/21 Slavistica

description: Partendo da considerazioni generali sulle connessioni fondamentali tra lingua e
cultura, la studiosa affronta il problema sottile del rapporto tra lingua nazionale e
pensiero e il dilemma sulla natura ‘locale’ o ‘universale’ della coscienza linguistica.
Presenta i risultati di un’indagine imperniata sulle attuali direzioni della linguistica
russa, in particolare quelle sviluppate nell’ambito della Teoria della comunicazione
interculturale. Questa branca si colloca tra la linguistica cognitiva, la psicolinguistica
e l’etnolinguistica e si basa su teorie che riguardano la nozione di personalità
linguistica e ciò che viene qui descritto come ‘quadro linguistico del mondo’.
Secondo l’autrice, questi sono entrambi sempre ‘nazionali’, in quanto esprimono la
visione di un certo popolo. Il ‘quadro linguistico’ è infatti costituito in primo luogo
da un lessico che è, in prevalenza, determinato nazionalmente. Tuttavia, l’autrice va
oltre il comune limite di studi analoghi per chiedersi se morfologia e sintassi (e non
solo lessico) possono anch’essi testimoniare le particolarità della ‘mentalità
nazionale’, fornendo a questo proposito una ricca esemplificazione di mezzi
espressivi e valutativi.
I concetti chiave della ricerca sono: coscienza linguistica, personalità linguistica,
quadro linguistico del mondo e lessico determinato nazionalmente.

description: We consider the geometry of second order linear operators acting on the commutative algebra of densities on a (super)manifold introduced in our previous work. In the conventional language, operators on the algebra of densities correspond to operator pencils. This algebra has a natural invariant scalar product. We consider self-adjoint operators on the algebra of densities and analyze the corresponding "canonical operator pencils" passing through a given operator on densities of a particular weight. There are singular values for the pencil parameters. This leads to an interesting geometrical picture. In particular we obtain operators that depend on equivalence classes of connections and we study a groupoid of connections such that the orbits of this groupoid are these equivalence classes. Based on this point of view we analyze two examples: the second order canonical operator on an odd symplectic supermanifold appearing in the Batalin-Vilkovisky geometry and the Sturm-Liouville operator on the line related with classical constructions of projective geometry. We also consider a canonical second order semidensity arising on odd symplectic supermanifolds, which has some resemblance with mean curvature in Riemannian geometry.

Stereotypes of "primitivism" and "modernity" in immigrant-related discourse in the Italian media
Creators: name: Rudvin, Mette
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2007
Subjects: L-LIN/12 Lingua e traduzione - Lingua inglese

description: Con questo saggio, Mette Rudvin ci porta alle funzioni del primitivismo nelle cronache odierne, esaminando le occorrenze del paradigma “immigrato/ straniero = primitivo” in un piccolo corpus di testi scritti e orali tratti dai media – che comprendono telegiornali, articoli e anche talk show politici italiani che vertono sul fenomeno dell’immigrazione – e mostrando come i miti occidentali del primitivismo vengano rappresentati linguisticamente. 
Lo studio, saldamente ancorato nelle teorie postcoloniali, rivela come il discorso popolare e giornalistico sull’immigrato si forgi sui più svariati e soventi contradditori miti occidentali del primitivo – da quello del “buon selvaggio” in armonia con la natura, a quello del ‘selvaggio bestiale e incivile’, fino a quello del ‘selvaggio irrazionale e/o sensuale’, tutte modalità di rappresentazione dell’altro come subalterno. L’analisi documenta non solo come il ‘mito’ del primitivismo si concretizzi nelle rappresentazioni dell’immigrazione che emergono sia dai discorsi di carattere apertamente razziale che da quelli presunti ‘liberal’, ma anche i modi in cui tali rappresentazioni contribuiscono a riproporre e istituzionalizzare i pregiudizi stereotipati di lettori, la cui dieta giornaliera di ‘notizie’ alimenta timori dell’altro, piuttosto che offrire narrazioni positive di individui appartenenti a civiltà differenti, che potrebbero costituire il potenziale per la creazione di rinnovati e migliori paradigmi culturali da contrapporre ad antichi ed anacronistici miti.

description: Social science research often utilizes measurement instruments that generate ordinal data (e.g., Likert scales). Many empirical studies also face the challenge of missing data, which can be addressed by performing multiple imputation followed by analyses of the imputed datasets. However, when missing data exist on ordinal variables, there has been limited research on how to evaluate model fit of structural equation models for ordinal variables. Recent studies suggest that two multiple-imputation-based approaches show great promise: The D2 procedure, and the Multiple Imputation Two-step (MI2S) approach, though the two have not been systematically compared. This study extends previous research by comparing the D2 with the MI2S fit statistics in a wider range of conditions than previous studies. Our findings revealed a number of factors that can influence the performance of these test statistics.

description: Gli elementi di analogia tra il templum augurale di Bantia e la forma urbana della città etrusca di Marzabotto hanno rivelato il perdurare di una concezione spaziale del templum augurale diversa da quella comunemente accettata. Quale è allora il significato rituale di tale concezione? In questo lavoro si sostiene il fondamento cosmologico di una concezione rituale dello spazio che coniuga i "templa" delle tre dimensioni cosmiche (celeste,terrestre,ed infera) con la figura del "templum solare del luogo". A quest'ultima figura geometrica sarebbero riferiti i modelli applicati nel corso del rito di fondazione, secondo uno schema concettuale che sembra ispirato ai fondamenti della aritmo-geometria di ascendenza pitagorica.

description: Advanced materials for separating the oil-water emulsions are highly desired for practical applications. Herein, robust superhydrophobic meshes with controllable pore size were prepared by electrodeposition and post-modification process. The influences of the textured roughness and hydrophobic modification on the surface wettability were explored. The superhydrophobic meshes exhibited superior stability against mechanical damages and various harsh conditions. By virtue of their superhydrophobicity and superoleophilicity, the mesh was successfully applied for the rapid and efficient separation of water-in-oil emulsions solely by gravity. This developed strategy for constructing robust superwetting membranes display huge application potential for wastewater treatment and oil purification.
Counselling? No, thanks! : an interpretive description of street-involved youth
Creators: name: Kucukbumin, Asli
Publisher: name: University of British Columbia

description: This thesis is an interpretive description of street-involved youth refusing counselling; it has two primary research questions. The first research question asked why street-involved youth refused counselling, and the second research question investigated research participants’ advice to counsellors who want to work with this population. Data collection comprised of semi-structured interviews with seven people. These seven people were recruited as they have current or past experiences of being street-involved youth who refused counselling. This interpretive description was informed by thematic analysis. Findings of this study suggested that street-involved youth’s reasons for refusing counselling are embedded in their perception of counselling, their experiences of counselling, and their desire to protect themselves. Research participants’ advice to counsellors who would like to work with this population also emerged in three layers: increasing counselling’s accessibility for street-involved youth, building connections with street-involved youth, and using street-involved youth friendly interventions. Findings emphasized the significance of counsellor-youth relations and the time and patience such relations may require. Findings also demonstrated a need to re-evaluate forced counselling and suggested to give youth more control over their counselling experiences.
