description: I believe part of the drive in my writing is an impulse to define poetry. The desire to fully satisfy this curiosity is something I find endlessly interesting, and amusing. In conclusion, I have found that a creative approach is the only authentic response. Therefore, my thesis has come to represent a personal exploration towards this interest. I have used my writing to flesh out what this might mean and always had the ambition these poems would add further mystery to the question. This is the underlying ethos of my work. Here, I attempt to sometimes communicate feeling more than sense, sensation over rational thought – all things I find poetry satisfies in myself. This has encouraged me to use sound and sense in experimental ways, as well as further investigate the spaces created by the imagination in the normal workaday reality of the world. As a result, I discovered a surreal approach comes very naturally to me. However, I strive to create a balance as well as a unique take towards this style. I think poetry should be fun to read, too. Quiet and loud. Abstract and grounded. And I assert that prose poems can be just as poetical as more recognisable forms. Just like the mythical hill worms talked about in ancient folklore, I think poetry should be intangible and mysterious. Funny and profound. This also ties into other themes which encourage my writing: childhood, imagination, love, art, animals, hobbies, our environment, and perhaps an overarching theme of how our individuality interacts within these – what I believe to be – spiritual spheres. And whether individuality as well as the imagination, like poetry, is something that cannot be specified, and is perhaps, moreover, a complex, evolving idea involving our geography and our shared and personal histories.

Electron-phonon mediated superconductivity probed by ARPES : from MgB2 to lithium-decorated graphene
Creators: name: Ludbrook, Bartholomew Mears
Publisher: name: University of British Columbia
Year: 2014

description: This thesis traces a path from conventional superconductivity in a bulk material to the introduction of superconductivity and other novel phenomena in graphene. Magnesium diboride is a conventional superconductor, where the pairing is mediated by the electron-phonon coupling. ARPES (angle resolved photoemission spectroscopy) is shown to be an excellent probe to quantitatively study the momentum dependence of the electron-phonon coupling, demonstrating the origin of the distribution of superconducting gap sizes previously observed with other experimental techniques. Next, we exploit our understanding of the electron-phonon coupling to study how it can be tuned in a low dimensional system. It is shown that the electron-phonon coupling in graphene can be strongly enhanced by the deposition of alkali adatoms. High resolution, low temperature ARPES measurements provide the first experimental evidence of superconductivity in this two-dimensional system, showing a temperature dependent pairing gap, and an estimated Tc of ~ 6K. Finally, we present a study of another graphene-adatom system expected to show novel physics. Thallium on graphene has been predicted to enhance the spin-orbit coupling, leading to a robust topological insulator state. From ARPES measurements characterizing this system, we disentangle the long-range and short-range scattering contributions and show that thallium atoms act as surprisingly strong short-range scatterers. Our results are consistent with theoretical predictions for this system, indicating it is a good place to search for a two-dimensional topological insulator.

description: The dynamics of a cloud of ultra-cold two-level atoms is studied at off-resonant laser driving to a Rydberg state. We find that resonant excitation channels lead to strongly peaked spatial correlations associated with the buildup of asymmetric excitation structures. These aggregates can extend over the entire ensemble volume, but are in general not localized relative to the system boundaries. The characteristic distances between neighboring excitations depend on the laser detuning and on the interaction potential. These properties lead to characteristic features in the spatial excitation density, the Mandel $Q$ parameter, and the total number of excitations. As an application an implementation of the three-atom CSWAP or Fredkin gate with Rydberg atoms is discussed. The gate not only exploits the Rydberg blockade, but also utilizes the special features of an asymmetric geometric arrangement of the three atoms. We show that continuous-wave off-resonant laser driving is sufficient to create the required spatial arrangement of atoms out of a homogeneous cloud.

description: Weathering acts with different intensities and rates on natural and artificial stones based on the dominant environmental conditions at a given area on one hand, limits of geotechnical parameters and durability of a given rock on the other hand. Recently, the environmental conditions became aggressive resulting in a severe damage to one of the most valuable and economic sectors at any country “the archaeological sites with its engraves and paintings”. El-Silsila sandstone is the most commonly used rock for building (in the past) and restoration (recently) of many archaeological sites in Egypt. This paper aims to determine damage category of construction sandstone at arid regions taking Seti I Temple at Qurna “Upper Egypt” that had been built from the Upper Cretaceous sandstone of El-Silsila quarries as a case study; also, it aims to find out if a detailed field investigations, measuring dimensions of all weathering forms and field data processing using linear and progressive damage indices equations can in a semi-quantitative form verify the same damage category that can be quantitatively determined using a detailed laboratory analyses or not. Detailed measurements of weathering forms’ dimensions had been conducted and processed graphically and mathematically. Laboratory analyses including petrographic investigation, hydrochemical analysis and geotechnical investigations had been conducted for the rock samples collected from the study area. Both of field and laboratory investigations revealed that Seti I Temple has severe to very severe damage category as a whole site, also it revealed that salt weathering severely affect on the lower courses of this site. In addition, it has been proved that detailed field study and its data processing can to a great extent replace the laboratory investigations that require rock sampling that might be im-permissible at some cases.

description: The paper is devoted to the thermodynamic derivation of a two-component poroelastic model with balance equation of porosity as a prototype of Biot's model. It is shown that a constitutive dependence on the porosity gradient yields the possibility of the construction of the linear Biot's model of poroelastic materials provided one negelcts the relaxation of porosity. A procedure of micro-macrotransition for a homogeneous microstructure yields Gassmann relations as an approximation of the thermodynamic model. Simultaneously it is shown that the model with the porosity balance equation can be applied to porous materials with a rather rigid skeleton. In the case of soft granular materials there exists a correction to porosity changes which follow from an appropriate modification of the porosity source.
The influence of a pediatric palliative care program on health care utilization and costs
Creators: name: Conte, Tania
Publisher: name: University of British Columbia
Year: 2015

description: Pediatric palliative care program (PPCP) is believed to increase system efficiency. British Columbia (BC) relies on a free-standing hospice-based PPCP, and its effects on health care utilization and costs remain an outstanding question. This study aimed to gather evidence in a combined analysis of data from literature and BC PPCP. A systematic review was conducted through an electronic search of Medline, Embase, CINAHL, LILACS, and grey literature. Comparative studies reporting admissions, length of stay, and health care costs between PPCP users and usual care were included. Additionally, a similar comparison was applied to the data from BC PPCP using a retrospective matched-pairs cohort design (matched by ICD code and age at death) with a 3-year observational period prior to death. Data were obtained from Canuck Place Children’s Hospice and BC Children’s Hospital databases, and complemented by estimates from Canadian Institute for Health Information. A cost impact of the overall inpatient care provided by the hospice was presented. The review did not demonstrate a decrease in utilization by PPCP users yet suggested a shift to other health care settings, and potential cost saving in the Canadian context (1 article). The cohort study (n=11 pairs), suggests that children in both groups had similar upward trends in inpatient utilization and cost. However, PPCP users showed more inpatient care in the last year of life (especially critical care in the last 2 months), compared to their controls and to the period prior to referral. Post-referral, a shift in health care setting utilization from hospital to hospice was observed, representing approximately 50% of the costs. Without this shift PPCP users would have cost 32% more with a median monthly increment of $7,163 per child. All inpatient care provided by the hospice in the fiscal year 2011-2012 represented a potential cost saving ranging from approximately $1.1M to $4.3M. The findings of this study suggest that PPCP users may present higher health care needs, and that the shift of inpatient care to the hospice optimized resource use, offering a more holistic approach to EOL care, relieving hospital resources to meet other demands.

description: A set of 55 clarinet reeds is observed by holography, collecting 2 series of measurements made under 2 different moisture contents, from which the resonance frequencies of the 15 first modes are deduced. A statistical analysis of the results reveals good correlations, but also significant differences between both series. Within a given series, flexural modes are not strongly correlated. A Principal Component Analysis (PCA) shows that the measurements of each series can be described with 3 factors capturing more than $90\%$ of the variance: the first is linked with transverse modes, the second with flexural modes of high order and the third with the first flexural mode. A forth factor is necessary to take into account the individual sensitivity to moisture content. Numerical 3D simulations are conducted by Finite Element Method, based on a given reed shape and an orthotropic model. A sensitivity analysis revels that, besides the density, the theoretical frequencies depend mainly on 2 parameters: $E_L$ and $G_{LT}$. An approximate analytical formula is proposed to calculate the resonance frequencies as a function of these 2 parameters. The discrepancy between the observed frequencies and those calculated with the analytical formula suggests that the elastic moduli of the measured reeds are frequency dependent. A viscoelastic model is then developed, whose parameters are computed as a linear combination from 4 orthogonal components, using a standard least squares fitting procedure and leading to an objective characterization of the material properties of the cane \textit{Arundo donax}.
Salt Weathering of Porous Structures Related to Climate Changes

description: The relationship between environmental conditions and the growth and dissolution of salts has been studied in specific areas of three different monuments. For this purpose, a non destructive method „Monitoring of the crystallization of salts in combination with climate measurements“ was developed which allows an understanding of the interaction between the existing salts and the ambient climate. In the crypt of St. Maria im Kapitol damage and decay of stones and wallpaintings have been caused by cyclic crystallization and dissolution of the salts halite [NaCl] and nitratine [NaNO3] controlled by climate changes through the heating of the crypt. In the choir of St. Johannes in Mußbach wallpaintings are weathered by temperature controlled crystallization of niter [KNO3]. In the Grottensaal of the New Palace in Potsdam the walls are deteriorated by crystallization of mirabilite [Na2SO4.10 H2O] and its transformation into thenardite [Na2SO4] and vice versa (dehydration / hydration) which is controlled by the surrounding climate (temperature and relative humidity). Understanding the behaviour of soluble salts in relation to the existing climate an appropriate conservation program can be developed.
Die Kristallisation und Auflösung von bauschädlichen Salzen in Abhängigkeit von den Umweltbedingungen wird anhand dreier Beispiele beschrieben. Die Herangehensweise „Monitoring von Salzkristallisationen in Kombination mit Klimamessungen“ wurde als Methode entwickelt, um das Zusammenspiel zwischen Salzaktivitäten und den umgebenden Klimafaktoren an einem Bauwerk zu erfassen. In der Krypta von St. Maria im Kapitol in Köln verursacht zyklisches, durch Heizung initiiertes Kristallisieren der Salze Halit [NaCl] und Nitronatrit [NaNO3] die Schädigung von Baustein und Wandmalereien. Im Chor von Mussbach werden Wandmalereien durch Temperatur-bedingtes Kristallisieren des Salzes Nitrokalit [KNO3] beeinträchtigt. Im Grottensaal des Neuen Palais in Potsdam verwittern einzelne Oberflächen durch klimagesteuerte Umwandlung (Hydratbildung) des Salzsystems Thenardit [Na2SO4] und Mirabilit [Na2SO4.10 H2O]. Das Wissen um die an einem Bauwerk vor sich gehenden Verwitterungsprozesse ist die Grundvoraussetzung für die Entwicklung eines angemessenen Konservierungskonzeptes.

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We investigate the behavior of the anomalous correlation function in two dimensional Bose gas. In the local case, we find that this quantity has a finite value in the limit of weak interactions at zero temperature. The effects of the anomalous density on some thermodynamic quantities are also considered. These effects can modify in particular the chemical potential, the ground sate energy, the depletion and the superfluid fraction. Our predictions are in good agreement with recent analytical and numerical calculations. We show also that the anomalous density presents a significant importance compared to the non-condensed one at zero temperature. The single-particle anomalous correlation function is expressed in two dimensional homogenous Bose gases by using the density-phase fluctuation. We then confirm that the anomalous average accompanies in analogous manner the true condensate at zero temperature while it does not exist at finite temperature.

description: (Abridged) We analyzed the {\it Chandra} and {\it XMM-Newton} archival observations for 72 type 2 quasars at $z<1$. These objects were was selected based on the [O III]$λ$5007 optical emission line which we assume to be an approximate indicator of the intrinsic AGN luminosity. We find that the means of the column density and photon index of our sample are $\log N_{\rm H}=23.0$ cm$^{-2}$ and $Γ=1.87$ respectively, which are consistent with results from deep X-ray surveys. The observed ratios of hard X-ray and [O III] line luminosities imply that the majority of our sample suffer significant amounts of obscuration in the hard X-ray band. A more physically realistic model which accounts for both Compton scattering and a potential partial covering of the central X-ray source was used to estimate the true absorbing column density. We find that the absorbing column density estimates based on simple power-law models significantly underestimate the actual absorption in approximately half of the sources. Eleven sources show a prominent Fe K$α$ emission line, and we detect this line in the other sources through a joint fit (spectral stacking). The correlation between the Fe K$α$ and [O III] fluxes and the inverse correlation of the equivalent width of Fe K$α$ line with the ratio of hard X-ray and [O III] fluxes is consistent with previous results for lower luminosity Seyfert 2 galaxies. We conclude that obscuration is the cause of the weak hard X-ray emission rather than intrinsically low X-ray luminosities. We find that about half of the population of optically-selected type 2 quasars are likely to be Compton-thick. We also find no evidence that the amount of X-ray obscuration depends on the AGN luminosity (over a range of more than three orders-of-magnitude in luminosity).

description: We extend our study of Motion Planning via Manifold Samples (MMS), a general algorithmic framework that combines geometric methods for the exact and complete analysis of low-dimensional configuration spaces with sampling-based approaches that are appropriate for higher dimensions. The framework explores the configuration space by taking samples that are entire low-dimensional manifolds of the configuration space capturing its connectivity much better than isolated point samples. The contributions of this paper are as follows: (i) We present a recursive application of MMS in a six-dimensional configuration space, enabling the coordination of two polygonal robots translating and rotating amidst polygonal obstacles. In the adduced experiments for the more demanding test cases MMS clearly outperforms PRM, with over 20-fold speedup in a coordination-tight setting. (ii) A probabilistic completeness proof for the most prevalent case, namely MMS with samples that are affine subspaces. (iii) A closer examination of the test cases reveals that MMS has, in comparison to standard sampling-based algorithms, a significant advantage in scenarios containing high-dimensional narrow passages. This provokes a novel characterization of narrow passages which attempts to capture their dimensionality, an attribute that had been (to a large extent) unattended in previous definitions.

The Treatment of Wall Paintings affected by Salts: An Interdisciplinary Task as seen from a Conservator’s Perspective

description: The interdisciplinary collaboration and implications between scientist, scientist in conservation and conservator is focused from the point of view of the conservator, facing conservation problems in the field of salt damaged wall paintings. Two case studies, the outdoor paintings of the castle of Parz of the late 16th century and the Romanesque wall painting cycle of St. Georgen, are discussed in the context of conservation history of the last two decades. The façade paintings of Parz, covering more than 600 m², were threatened by severe degradation due to sulfatation and weathering. The application of the Florentine method using ammoniumcarbonate and bariumhydroxide gave reasonable good results in cleaning and consolidation. This treatment was the first step to introduce this method to wall paintings conservation, outside of Italy. The indoor paintings of St. Georgen of Judenburg represents one of the main important discovery of wall paintings of the 13th century in Austria in the last two decades. The paintings were threatened crystallization of various salts, due to rising damp, water infiltration and salt containing building materials, resulting in a solution of soluble salts that could be defined as a real “explosive cocktail”. The impact of the application of several conservation treatments, like the introduction of a drainage system, elimination of cement plasters, extraction of soluble salts by paper pulp compresses, and the use of ion-exchange systems by ion exchange resins, ammoniumcarbonate and barium hydroxide is discussed. First steps done in 1988 based on empirical experiences were followed by a period of scientific research, resulting finally in the application of a stabilization treatment. After eight years the situation is still stable and can be seen as a basis for a continuous maintenance program.

description: The process of gluon-initiated double Higgs production is sensitive to non-linear interactions of the Higgs boson. In the context of the Standard Model, studies of this process focused on the extraction of the Higgs trilinear coupling. In a general parametrization of New Physics effects, however, an even more interesting interaction that can be tested through this channel is the (ttbar hh) coupling. This interaction vanishes in the Standard Model and is a genuine signature of theories in which the Higgs boson emerges from a strongly-interacting sector. In this paper we perform a model-independent estimate of the LHC potential to detect anomalous Higgs couplings in gluon-fusion double Higgs production. We find that while the sensitivity to the trilinear is poor, the perspectives of measuring the new (ttbar hh) coupling are rather promising.

description: The mechanism of damage due to NaCl crystallization has not been clarified yet. Apart from crystallization pressure, other hypotheses have been proposed to explain the decay. Irreversible dilation during NaCl crystallization has been observed in a few cases but has never been studied in a systematic way. In this paper the effect of NaCl on the hydric and hygric behaviour of a lime/cement mortar is extensively studied. NaCl is shown to modify the hydric and hygric dilation behavior of the material. The material contaminated with NaCl shrinks during dissolution and dilates during crystallization of the salt. This dilation is irreversible and its amount is sufficient to cause damage after few dissolution/crystallization cycles. A similar behaviour has been also observed in the presence of NaNO3 and KCl. If a crystallization inhibitor, modifying crystallization habits of the salt, is added to the NaCl, no irreversible dilation occurs. Outcomes of electron microscopy studies suggest that a relation exists between crystallization habit of the salt and dilation behaviour. Salts crystallizing as a layer adhering to the pore walls seem able to cause relevant expansion during drying of the specimen and crystallization of the salt. A similar effect is, in this theory, not possible when the same salt crystallizes without adhering to the material, as in the presence of the crystallization inhibitor.

description: A hydrophilic floating sphere that is denser than water drifts to an amplitude maximum (antinode) of a surface standing wave. A few identical floaters therefore organize into antinode clusters. However, beyond a transitional value of the floater concentration $ϕ$, we observe that the same spheres spontaneously accumulate at the nodal lines, completely inverting the self-organized particle pattern on the wave. From a potential energy estimate we show (i) that at low $ϕ$ antinode clusters are energetically favorable over nodal ones and (ii) how this situation reverses at high $ϕ$, in agreement with the experiment.

description: In a set of experiments, Couder et. al. demonstrate that an oscillating fluid bed may propagate a bouncing droplet through the guidance of the surface waves. We present a dynamical systems model, in the form of an iterative map, for a droplet on an oscillating bath. We examine the droplet bifurcation from bouncing to walking, and prescribe general requirements for the surface wave to support stable walking states. We show that in addition to walking, there is a region of large forcing that may support the chaotic bouncing of the droplet. Using the map, we then investigate the droplet trajectories for two different wave responses in a square (billiard ball) domain. We show that for waves which are quickly damped in space, the long time trajectories in a square domain are either non-periodic dense curves, or approach a quasiperiodic orbit. In contrast, for waves which extend over many wavelengths, at low forcing, trajectories tend to approach an array of circular attracting sets.

description: The Fermat quotient $q_p(a):=(a^{p-1}-1)/p$, for prime $p\nmid a$, and the Wilson quotient $w_p:=((p-1)!+1)/p$ are integers. If $p\mid w_p,$ then $p$ is a Wilson prime. For odd $p,$ Lerch proved that $(\sum_{a=1}^{p-1} q_p(a) - w_p)/p$ is also an integer; we call it the Lerch quotient $\ell_p.$ If $p\mid\ell_p$ we say $p$ is a Lerch prime. A simple Bernoulli-number test for Lerch primes is proven. There are four Lerch primes 3, 103, 839, 2237 up to $3\times10^6$; we relate them to the known Wilson primes 5, 13, 563. Generalizations are suggested. Next, if $p$ is a non-Wilson prime, then $q_p(w_p)$ is an integer that we call the Fermat-Wilson quotient of $p.$ The GCD of all $q_p(w_p)$ is shown to be 24. If $p\mid q_p(a),$ then $p$ is a Wieferich prime base $a$; we give a survey of them. Taking $a=w_p,$ if $p\mid q_p(w_p)$ we say $p$ is a Wieferich-non-Wilson prime. There are three up to $10^7$, namely, 2, 3, 14771. Several open problems are discussed.

description: Changes in the air RH can cause damage to building materials contaminated with hygroscopic salts, even in the absence of any other moisture source. This phenomenon has been observed in the case of the Waag building in Amsterdam, affected by severe salt decay. The investigation, carried out by means of different techniques (e.g. ESEM-EDX, IC and XRD), has revealed the presence in the masonry of a large amount of hygroscopic salts (mainly sodium chloride and nitrates) and the absence of any moisture sources other than the RH of the air. Besides, an adsorption experiment performed on samples from the building has pointed out the hygroscopic moisture uptake of the salt mix even at low RH. These results, in combination with a monitoring of the interior climate for a period of about 1 year, have allowed to conclude that the damage observed is due to the frequent RH changes through the equilibrium where dissolution/crystallization of the salt mix takes place. On the basis of these findings an advice for the conservation of the building was given.

description: From observational data alone, a causal DAG is only identifiable up to Markov equivalence. Interventional data generally improves identifiability; however, the gain of an intervention strongly depends on the intervention target, that is, the intervened variables. We present active learning (that is, optimal experimental design) strategies calculating optimal interventions for two different learning goals. The first one is a greedy approach using single-vertex interventions that maximizes the number of edges that can be oriented after each intervention. The second one yields in polynomial time a minimum set of targets of arbitrary size that guarantees full identifiability. This second approach proves a conjecture of Eberhardt (2008) indicating the number of unbounded intervention targets which is sufficient and in the worst case necessary for full identifiability. In a simulation study, we compare our two active learning approaches to random interventions and an existing approach, and analyze the influence of estimation errors on the overall performance of active learning.

description: Salze und Verwitterungsmechanismen, die mit Salzen in Verbindung stehen, sind eine Hauptursache des Zerfalls von Denkmalen. Salzbelastungen an Bauwerken, Malerei und Skulptur stellen eine Fülle unterschiedlicher Aufgaben an Restauratoren und Denkmalpfleger. Hierzu zählt ganz wesentlich die Untersuchung einer Salzbelastung. Gegenstand der vorliegenden Diplomarbeit ist die Darstellung eines Untersuchungsverfahrens zur qualitativen Bestimmung bauschädlicher Salzphasen. Die Zielsetzung besteht darin, wenig aufwendige Tests mit einfachen polarisationsmikroskopischen Untersuchungen in einen Methodensatz zusammenzubringen, welches es Fachleuten der Restaurierung ermöglicht, Salzbestimmungen in einem bestimmten Rahmen eigenständig durchzuführen. In Teil 1 der Diplomarbeit wird der Methodensatz detailliert und anwendungsbezogen erläutert. Anhand von mehreren Fallbeispielen wird zudem die praktische Durchführung der Analyse verdeutlicht. Die Beobachtungen, die im Zuge der Untersuchungen gemacht werden, ermöglichen die Bestimmung eines Salzes. Die Nutzung der Beobachtungen zur eigentlichen Salzzuweisung kann effizient durch die Zuhilfenahme einer Arbeitsdatenbank erfolgen, welche mit der Diplomarbeit vorgelegt wird. Im zweiten Teil der Diplomarbeit sind für ausgewählte Salzphasen Angaben zu deren Schadenspotential sowie Erläuterungen ihrer Identifikationsmerkmale in einzelnen Dossiers zusammengestellt. Jedes der Dossiers schließt mit einem Bildatlas, in welchem visuelle Kennzeichen der Salze aufgezeigt sind.
Specific salts are generally assumed to be one of the main reasons for the decay of monuments due to their deteriorating activity. Whenever buildings, wall paintings or sculptures made of stone suffer salt contamination, various tasks have to be tackled by restorers and conservators. First of all an orientating examination of the contamination will have to be carried out. Subject of this diploma study is the description of methods for the qualitative analysis of salts. Uncomplicated tests and simple examinations by means of the polarising microscope can be combined in order to enable restorers and conservators to carry out the analysis by themselves, within certain bounds. The first part of the diploma contains a thorough and functional description of approaches and analyzing techniques. With the help of case studies the practicability of the entire method is explained. In order to utilize efficiently the information that has been obtained during the different examinations a data base can be used which was designed as part of the diploma. Part two of the diploma is a compilation. Information about the weathering action of selected salts as well as important chemical and physical properties that permit their identification are compiled in seven dossiers. Each of them includes a photographic atlas that demonstrate the salt’s visual characteristics.
Light transmissive variable thermal insulator based on nonimaging optics with potential application in cold climate greenhouses.

description: Greenhouse structures have demonstrated success enhancing crop yields in farmlands, but the energy for thermal control and lighting make them impractical in cold weather locations because traditional greenhouse construction techniques result in a trade-off between light transmission and thermal insulation. The objective of the project described in this dissertation was to conceptualize, design and test a practical solution to the light transmission and thermal insulation trade-off challenge. The system that was developed is a variable light valve system that can be switched between two states – in one state the system acts as a sunlight transparent window and the other state the system acts as a highly thermally insulated ceiling capable of keeping the structure warm in cold weather conditions. Switching between the two states requires only a simple, low-cost rotation mechanism. The possibility of extending the hours of operation for the light valve system by adjusting the angular position of its light valve elements was also explored. The light valve system when in its highly thermally insulated state, demonstrated a thermal insulation value above 3.33 m²K/W and 70% light transmittance when in its light transmissive state. In order to achieve this thermal insulation value, air mass transfer losses through the light valve structure were reduced by the implementation of low pressure seal. The experimental devices used to test the light valve system demonstrated it can be constructed using inexpensive and readily available materials. The project described in this dissertation has successfully confirmed a practical solution to reduce the energy use for heating in cold climate greenhouses while maintaining appropriate sunlight transmittance through their structure. The light valve system may represent a practical alternative for cold climate greenhouse horticulture.

description: In der vorliegenden Arbeit wurde der Einfluss supramolekularer Chiralität auf den schwingungszirkularen Dichroismus untersucht. Die experimentelle Basis lieferten Messungen an neuartigen thermotropen flüssigkristallinen Phasen, den so genannten Lamellaren Phasen, die von bolaamphiphilen Mesogenen gebildet werden. Wie gezeigt werden konnte neigen die Phasen zur spontanen Ausbildung großer monochiraler Domänen auch bei der Verwendung razemischer Mischungen der Mesogene. Während alle molekularen VCD-Effekte bei den verwendeten Verbindungen vernachlässigt werden konnten, sind die Signale in den chiralen Domänen ungewöhnlich stark. Für die Interpretation der Spektren wurden die Modelle der gekoppelten Oszillatoren aufgegriffen und erweitert. Die Mesogene wurden durch einen Satz bipolar Oszillatoren beschrieben. Die Kopplung einer räumlich ausgedehnten Ansammlung von Oszillatoren über Hertzsche Nahfelder erlaubt die Beschreibung der zirkular dichroischen Effekte mit Hilfe der klassischen Physik. Die Zurückführung der sich aus dem Modell ergebenden Differentialgleichungen auf ein lineares Gleichungssystem erlaubt die effiziente Modellierung der VCD-Spektren supramolekularer Systeme von geringer Symmetrie und Ordnung.
description: The influence of supramolecular chirality on the vibrational circular dichroism is the subject of this work. The experimental base are measurements on novel thermotropic liquid crystalline phases, so called Lamellar Phases, formed by bolaamphiphile mesogens. It could be shown that the phases tends to the spontaneous formation of large monochiral domains even in case of the use of racemic mixtures of mesogens. During the molecular VCD effects of the substances are negligible the signals of the chiral domains are exceptional strong. To interpret the spectral results the models of coupled oscillators are taken up and extended. The mesogens are described by a set of bipolar oscillators. The description of circular dichroic effects fully based on classical physics is done by the coupling of a spatial distributed ensemble of oscillators by Hertz fields using a near field approximation. Reducing the differential equations of the model to a set of linear equations permits a efficient modeling of VCD spectra of supramolecular systems of less symmetry and order.
