Masterarbeit

description: Diese Masterarbeit beschäftigt sich mit der Kooperation von Schulischen Heilpädagoginnen und Heilpädagogen (SHPs) und Klassenlehrpersonen (KLPs). Aufgrund der literaturbasierten Auseinandersetzung mit verschiedenen Kooperationsformen und Gelingensbedingungen für Kooperation zeigt sich, dass die Absprachen des Kooperationsteams einen entscheidenden Einfluss auf das Gelingen ihrer Zusammenarbeit nehmen. Der Fokus dieser Masterarbeit liegt deshalb auf den wöchentlichen Absprachen zwischen SHPs und KLPs. Anhand transkribierter Audiodateien von Absprachen zwischen KLPs und SHPs wird der Frage nachgegangen, ob bei Kooperationsteams ein Kommunikationsmuster zu erkennen ist und welche Qualitätsmerkmale gelungener Kooperation sich in den Absprachen wiederspiegeln. Als Schlussfolgerung versucht die Autorin aufzuzeigen, wie die knappen Zeitressourcen, die das Lehrpersonal für Kooperationsabsprachen zur Verfügung hat, konstruktiv genutzt werden könnten.

description: El presente estudio pretende demostrar el efecto del ruido de voltímetros digitales en las determinaciones potenciométricas de cloruros, utilizando electrodos de vidrios desechados como indicadores selectivo de iones cloruros. Se elaboró un programa de simulación en Maple 18 que calcula el ruido en las mediciones de concentraciones de cloruros, considerando voltímetros con resoluciones de 1, 0.1 y 0.01 mV. En el programa se introdujo una desviación del volumen nominal del volumétrico utilizado en las adiciones de los estándares, con el n de simular los errores sistemáticos de un volumétrico no calibrado. Se estimaron las diferencias mínimas de potencial que deben existir para poder diferenciar dos concentraciones sucesivas. Estos valores fueron de 19, 2.9 y 1.2 mV respectivamente para los voltímetros anteriores. Se simuló el modelo de calibración para una resolución de 1 mV, voltímetro disponible en el laboratorio, y se comparó con el modelo experimental obtenido con un electrodo de vidrio desechado. El método se aplicó a las determinaciones de cloruros en suero siológico y en una muestra de agua de consumo, haciendo uso de la calibración directa y la de adición patrón. Se evaluaron las incertidumbres aplicando dos métodos de cálculo: la propagación de las incertidumbres y la de simulación de Montecarlo, lo que condujo a recomendar el uso de un voltímetro con mejor resolución para obtener resultados con mayor precisión.

description: We establish that unitarity of scattering amplitudes imposes universal entropy bounds. The maximal entropy of a self-sustained quantum field object of radius R is equal to its surface area and at the same time to the inverse running coupling evaluated at the scale R. The saturation of these entropy bounds is in one-to-one correspondence with the non-perturbative saturation of unitarity by 2-to-N particle scattering amplitudes at the point of optimal truncation. These bounds are more stringent than Bekenstein's bound and in a consistent theory all three get saturated simultaneously. This is true for all known entropy-saturating objects such as solitons, instantons, baryons, oscillons, black holes or simply lumps of classical fields. We refer to these collectively as "saturons" and show that in renormalizable theories they behave in all other respects like black holes. Finally, it is argued that the confinement in SU(N) gauge theory can be understood as a direct consequence of the entropy bounds and unitarity.

description: Se utilizo la implementación de estrategias eficaces en la utilización de recursos es de primera necesidad para los productores en las que disminuyan costos y menor impacto ambiental para cumplir con este objetivo se desarrolla el cultivo bajo el sistema de flóculos. La utilización de flóculos agrega al sistema de cultivo una mayor eficacia en la utilización del alimento ya que se recircula lo que no es consumido y los desechos metabólicos por la generación de microorganismos que se convierten en alimento con alta cantidad de proteína y mejor digestibilidad, se utiliza menor cantidad de agua por ser un sistema cerrado de cero recambio de agua, tiene mejor control de la bioseguridad y minimiza los efectos ambientales sobre la utilización del agua y su descarga. Como objetivo general esperamos determinar cuál de dos dietas alimenticias comerciales: (con floculo vs otro sin floculo), presenta mejores resultados en el crecimiento de tilapia en condiciones experimentales. El experimento se desarrolló en la comarca La Leona, en la Granja Integral de policultivo “La Esperanza”. Que se ubica a 9 km de la Ciudad de León. Este trabajo consto con dos tratamientos, alimento comercial (con floculo vs sin floculo) con tres repeticiones cada uno. En total se trabajó con 6 recipientes plástico con capacidad de 200 litros de agua, para los cuales se tuvieron 3 recipientes dispuestas para cada tratamiento, Se aplicó alimento comercial con floculo en el tratamiento 1 y en el tratamiento 2 se aplicó alimento comercial. Cada recipiente plástico fue sembrado con una cantidad de 6 peces/m², con pesos promedio de 5.1 gr para el tratamiento 1 y 5.5 gramos para el tratamiento 2, los cuales estuvieron por estudio durante 25 días. Según los resultados obtenidos los factores físico-químicos se mantuvieron en los valores de 24.9°C y 28.5°C influyendo sobre el crecimiento de las tilapias (Oreochromis niloticus) en cuanto al crecimiento se observó un mayor incremento en el tratamiento 1 con una diferencia de 1.66 gr. Por lo tanto se concluye que hubo un mayor crecimiento en el tratamiento 1 (alimento comercial + floculo).

title: Making Rules, Making Tools: How Can Shape Grammar Support Creative Making?
Creators: name: Maclachlan, Lynne
Publisher: name: The Open University

description: Design theory has previously studied the practices of architects, industrial designers and engineers. Designer-makers, designers who work independently, designing and making objects with close attention to tools and materials, have not been similarly studied. A renewed interest in craft and making, in part catalysed by new computational and digital fabrication tools at designer’s disposal, strengthens the case for studying successful design-through-making processes. An analogy between rules transforming shapes and tools transforming material provided the initial indication that concepts from shape grammar could be aligned with making processes, to potentially support creative making and deliver new theoretical and applied knowledge for both spheres. The first part of the thesis examines shape grammar theory as a method of modelling designer-maker creative episodes, to inform designer practice. Evidence was gathered from interviews with designer-makers, observations from a design process carried out by the author and other literature on designer-makers. This evidence was analysed in the context of shape grammar and established creativity literature in order to seek formal descriptions of creative episodes. It was found that designer-makers used tools to define personal and shared design worlds and focussed on and undertook specific activities relating to tools which have been classified; tool selection, tool combination and tool transformation, all of which have creative potential. Tool transformation was found to have further scope for definition and it was found that designers can perform parametric, functional and reformatting transformations on tools to produce new and useful design outcomes. Shape grammar schemas were found to provide useful descriptors for the operations performed by designer-makers on tools. The second part of the thesis inquires if shape grammar as a design method can support creative computational making, by specifically exploring the use of shape grammar weights, a way of modelling material properties alongside shape operations, as a tool for generating designs for multi-material 3D printing. A number of design reasoning and computational making experiments were carried out and the process and results reported and considered. The outcome is a range of specified weights systems and a general schema for defining and using weights as tool for managing material properties for multi-material 3D printing that can be used and transformed by computational makers. The general weights schema also extends previous theoretical definitions of shape grammar weights. This part of the thesis also demonstrated the importance of tool development and transformation as a basis for creative episodes in design-through-making processes.

description: The appropriate description of fluctuations within the framework of evolutionary game theory is a fundamental unsolved problem in the case of finite populations. The Moran process recently introduced into this context [Nowak et al., Nature (London) 428, 646 (2004)] defines a promising standard model of evolutionary game theory in finite populations for which analytical results are accessible. In this paper, we derive the stationary distribution of the Moran process population dynamics for arbitrary $2\times{}2$ games for the finite size case. We show that a nonvanishing background fitness can be transformed to the vanishing case by rescaling the payoff matrix. In contrast to the common approach to mimic finite-size fluctuations by Gaussian distributed noise, the finite size fluctuations can deviate significantly from a Gaussian distribution.

description: The treatment of fields as operator valued distributions (OPVD) is recalled with the emphasis on the importance of causality following the work of Epstein and Glaser. Gauge invariant theories demand the extension of the usual translation operation on OPVD, thereby leading to a generalized $QED$ formulation. At D=2 the solvability of the Schwinger model is totally preserved. At D=4 the paracompactness property of the Euclidean manifold permits using test functions which are decomposition of unity and thereby provides a natural justification and extension of the non perturbative heat kernel method (Fujikawa) for abelian anomalies. On the Minkowski manifold the specific role of causality in the restauration of gauge invariance (and mass generation for $QED_{2}$) is examplified in a simple way.

subject: FARMERS ADOPTION OF AGRICULTURAL MACHINERY IN EGYPT

description: There are two sets of agricultural mechanization systems in Egypt. The conventional for land preparation, irrigation and threshing) and non-conventional (for seeding, combine harvesting and land levelling by laser equipment). The last set is the focus of this study. The study objective is to identify the direction and magnitude of the major social and economic factors that affect the farmers adoption of such machinery systems. The study used the data of two field sample surveys conducted in 1985 / 1986 and 1992 ' 1993 from same area (the same districts of Sharkia Governorates) and representing the same farm size pattern. They survey concerned the farm operations, input-output data, with special emphasis on farm mechanization systems. The targets field crops of the surveys are (Wheat and Rice). The application of the mechanization system on farms over time is the indicator of adoption decision by farmers. The study showed that the economic factors that are significantly affecting the farmers adoption of non-conventional mechanization systems include The farms size, availability of family labor on farm, farm holding type, the distance from the agricultural mechanization station, farm income, the grain variety, quantity of chemical fertilizers. The social factors that are significantly affecting the farmers adoption of non-conventional mechanization systems include the number of years of education of both the farmer and his wife. The study concluded that the progressive farms are the most likely types of farms that adopt the non-conventional agricultural mechanization system in Egypt. The progressive farms are identified as of large acreage size, small family size, and which applies now high yield variety and into rive level of chemical fertilizers. This type of farms acquires high farm income.

description: Given a compact Kähler manifold, Geometric Invariant Theory is applied to construct analytic GIT-quotients that are local models for a classifying space of (poly)stable holomorphic vector bundles containing the coarse moduli space of stable bundles as an open subspace. For local models invariant generalized Weil-Petersson forms exist on the parameter spaces, which are restrictions of symplectic forms on smooth ambient spaces. If the underlying Kähler manifold is of Hodge type, then the Weil-Petersson form on the moduli space of stable vector bundles is known to be the Chern form of a certain determinant line bundle equipped with a Quillen metric. It gives rise to a holomorphic line bundle on the classifying GIT space together with a continuous hermitian metric.

Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this exploratory study was to evaluate the experiences of women who had donated their eggs to help a family member, friend, or acquaintance become a parent. An experimenter-generated questionnaire was distributed to all donors who had participated in the egg donation program at Genesis Fertility Centre since the egg donor program's inception in 1999. Of the 29 women who were able to be contacted, 20 elected to complete and return the questionnaire for a response rate of 69%. The first section of this three-part questionnaire sought to gather general information from the donor about: how the subject of being an egg donor first arose, the nature of the donor's relationship with/to the recipient, whether a viable pregnancy resulted from the cycle, and whether the donor's relationship with the recipient(s) has changed since she participated in treatment. The second part dealt with the decision-making process of the donor, and inquired about the importance of the following factors in the donor's decision to become an egg donor: the relationship of the donor to the recipient, personal factors, family factors, broader social issues, and consequences to the child(ren) produced if treatment was successful. The third section assessed the donor's experience in the treatment process as well as her overall experience of being an egg donor. Irrespective of the outcome of her donation or the challenges of the treatment process, 90% of the participants reported having no regrets about having donated their eggs to a family member, friend, or acquaintance. Given the chance to reconsider their decision, all but two participants said they would make the same choice again to be a known egg donor.

description: We have characterized the vertical transport properties of epitaxial layered structures composed of Pr$_{0.7}$Ca$_{0.3}$MnO$_{3}$ (PCMO) sandwiched between SrRuO$_{3}$ (SRO) bottom electrode and several kinds of top electrodes such as SRO, Pt, Au, Ag, and Ti. Among the layered structures, Ti/PCMO/SRO is distinct due to a rectifying current-voltage ($I$--$V$) characteristic with a large hysteresis. Corresponding to the hysteresis of the $I$--$V$ characteristics, the contact resistance of the Ti/PCMO interface reversibly switches between two stable states by applying pulsed voltage stress. We propose a model for the resistance switching at the Ti/PCMO interface, in which the width and/or height of a Schottky-like barrier are altered by trapped charge carriers in the interface states.

description: We present a physical model for the coevolution of massive spheroidal galaxies and active nuclei at their centers. Supernova heating is increasingly effective in slowing down the star formation and in driving gas outflows in smaller and smaller dark matter halos. Thus the more massive protogalaxies virializing at early times are the sites of faster star formation. The correspondingly higher radiation drag causes a faster angular momentum loss by the gas and induces a larger accretion rate onto the central black hole. In turn, the kinetic energy of the outflows powered by the active nuclei can unbind the residual gas in a time shorter for larger halos. The model accounts for a broad variety of dynamical, photometric and metallicity properties of early-type galaxies, for the M_BH -- σrelation and for the local supermassive black-hole mass function.

description: Circuit quantum electrodynamics (QED) employs superconducting microwave resonators as quantum buses. In circuit QED with semiconductor quantum-dot-based qubits, increasing the resonator impedance is desirable as it enhances the coupling to the typically small charge dipole moment of these qubits. However, the gate electrodes necessary to form quantum dots in the vicinity of a resonator inadvertently lead to a parasitic port through which microwave photons can leak, thereby reducing the quality factor of the resonator. This is particularly the case for high-impedance resonators, as the ratio of their total capacitance over the parasitic port capacitance is smaller, leading to larger microwave leakage than for 50-$Ω$ resonators. Here, we introduce an implementation of on-chip filters to suppress the microwave leakage. The filters comprise a high-kinetic-inductance nanowire inductor and a thin-film capacitor. The filter has a small footprint and can be placed close to the resonator, confining microwaves to a small area of the chip. The inductance and capacitance of the filter elements can be varied over a wider range of values than their typical spiral inductor and interdigitated capacitor counterparts. We demonstrate that the total linewidth of a 6.4 GHz and approximately 3-k$Ω$ resonator can be improved down to 540 kHz using these filters.
title: Evolutionary and Developmental Survey of Genes Involved in Chordate Pigmentation
Creators: name: Coppola, Ugo
Publisher: name: The Open University

description: The pigmentation represents one of the most interesting topics in animal life because it is a decisive factor for the evolutionary success and the conquest of new ecological niches. Through the combination of developmental biology and comparative genomics, some aspects of pigmentary dynamics have been studied.

 Given Rabs regulate a plethora of trafficking steps, the members belonging to this family are central to the transport of molecules involved in pigmentation. Moreover, comprehending the evolution of Rab family is relevant to understand the establishment of eukaryotic cellular organization and for its implication in many human pathologies. For the first time, I reconstructed the evolutionary scenario of Rab family in eleven species of metazoans, spanning from cnidarians to human. Phylogeny, intron code and synteny conservation prompted me to depict Rab evolution, with a special focus on chordates that exhibit a highly dynamic evolutionary pattern.

 I clarified the evolution of Rab32/38 subfamily, fundamental in regulation of trafficking related to melanogenesis. It has been clarified the evolutionary history of Rab32/38 genes in deuterostomes and the expression pattern in key species as zebrafish and amphioxus, demonstrating how events as whole-genome duplications have influenced their role during embryogenesis.

 In order to find new genes involved in pigmentation, I analyzed a Kelch-like member in ascidian Ciona robusta (Cr-Klhl21). My results point at this gene as a marker of pigmented cells, with a dynamic expression profile during embryogenesis: from middle tailbud stage, it is expressed specifically in the otolith. Moreover, Cr-Klhl21 shows an intricate regulatory scenario with the possible intervention of a transcription factors combination (Cr-Mitf, Cr-msxb, Cr-Dmrt). This work contains first data about a Kelch-like member in ascidians, providing new insights in pigmentation or pigment cell specification. This encourages further analyses on its gene regulatory network and possible function.

description: Die vorliegende Entwicklungsarbeit beschreibt den Prozess zur Realisierung einer App namens „TidyApp“ sowie deren Evaluation. Die TidyApp simuliert die alltägliche, wiederkehrende Situation des Aufräumens im Kindergarten. Sie hat den Anspruch, Kinder mit besonderem Förderbedarf in der Sprache durch Integration sprachfördernder Elemente im Aufbau eines Alltagswortschatzes zu unterstützen. Studien und Befunde zur Nutzung von Tablets und Apps im Vorschulalter als auch Erkenntnisse zu Ritualen und sprachfördernden Merkmalen für die Wortschatzerweiterung und - speicherung, bilden unter anderem die theoretische Grundlage zur Entwicklung dieses Unterrichtsinstrumentes. Die technische Entwicklung der TidyApp erfolgte unter Mitarbeit einer Informatikerin. Die App wurde im Rahmen der vorliegenden Arbeit an potenziellen Benutzern, wie Kindergartenkinder mit und ohne Sprachförderbedarf oder im Kindergarten tätigen Lehr- und Fachpersonen, getestet. Methodisch wurde die Datenerhebung mittels Beobachtung sowie über einen Fragebogen durchgeführt. Die Evaluationsergebnisse zeigen, dass die TidyApp insgesamt als verständlich, motivierend und lebensweltnah befunden wird. Findet die Anwendung der TidyApp in Partnerarbeit statt, so wirkt sich dies positiv auf den mündlichen Sprachgebrauch der Lernenden aus. Die Ergebnisse zeigen aber auch Optimierungsmöglichkeiten auf. Die TidyApp funktioniert auf dem iPad und kann gezielt als ergänzendes Spiel- und Lernmittel im Kindergarten eingesetzt werden.

description: Context: Type Ibn supernovae are a rare class of stripped envelope supernovae interacting with a helium-rich CSM. The majority of the SNe Ibn reported display a surprising homogeneity in their fast lightcurves and starforming hosts. Aims: We present the discovery and study of SN 2020bqj (ZTF20aalrqbu), a SN Ibn with a long-duration peak plateau lasting 40 days and hosted by a faint low-mass galaxy. We aim to explain its peculiar properties using an extensive data set. Methods: We compare the evolution of SN 2020bqj with SNe Ibn from the literature. We fit the bolometric and multi-band lightcurves with different powering mechanism models. Results: The risetime, peak magnitude and spectral features of SN 2020bqj are consistent with those of most SNe Ibn, but the SN is a clear outlier based on its bright, long-lasting peak plateau and low host mass. We show through modeling that the lightcurve can be powered predominantly by shock heating from the interaction of the SN ejecta and a dense CSM. The peculiar Type Ibn SN 2011hw is a close analog to SN 2020bqj, suggesting a similar progenitor and CSM scenario. In this scenario a very massive progenitor star in the transitional phase between a luminous blue variable and a compact Wolf-Rayet star undergoes core-collapse, embedded in a dense helium-rich CSM with an elevated opacity compared to normal SNe Ibn, due to the presence of residual hydrogen. This scenario is consistent with the observed properties of SN 2020bqj and the modeling results. Conclusions: SN 2020bqj is a compelling example of a transitional SN Ibn/IIn based on not only its spectral features, but also its lightcurve, host galaxy properties and the inferred progenitor properties. The strong similarity with SN 2011hw suggests this subclass may be the result of a progenitor in a stellar evolution phase that is distinct from those of progenitors of regular SNe Ibn.

description: We estimate final state interactions in the B-meson decays into two light vector mesons by the Regge model. We consider Pomeron exchange and charmed Regge trajectories that can relate intermediate charmed particles to the final state. The Regge poles have various helicity-flip residues, which allows a change from the longitudinal to transverse polarization. In this way a significant reduction of the longitudinal polarization fraction can be produced. In the factorization approximation we find agreement with recent data from the BaBar and Belle collaborations in the B => K* phi decay channel, as a result of an appropriate choice of semileptonic form factors and Regge exchanges. On the other hand, data for the K* rho decay channels appear more elusive. The soft effects discussed in the present paper are based on a model of Regge trajectories that is shown to reproduce correctly in the non-charmed case the Regge phenomenology of light mesons.

Refined mean field model of heat and momentum transfer in magnetoconvection

description: In this article, the theoretical model on heat and momentum transfer for Rayleigh-Bénard convection in a vertical magnetic field by Zürner et al. (Phys. Rev. E 94, 043108 (2016)) is revisited. Using new data from recent experimental and numerical studies the model is simplified and extended to the full range of Hartmann numbers, reproducing the results of the Grossmann-Lohse theory in the limit of vanishing magnetic fields. The revised model is compared to experimental results in liquid metal magnetoconvection and shows that the heat transport is described satisfactorily. The momentum transport, represented by the Reynolds number, agrees less well which reveals some shortcomings in the theoretical treatment of magnetoconvection.

Impact from an interface wildfire, place attachment, and depression : a survey of two rural communities
Creators: name: Handler, Risa Jordana
Publisher: name: University of British Columbia
Year: 2011

description: Disaster recovery research has overlooked the important role of place attachment in recovery to a natural disaster, particularly its association with the initial impact on residents and their mental health. Although increased depression immediately following a natural disaster is well documented, there is a paucity of research that has examined the long-term effects of natural disasters on depressive symptoms. Thus, I examined the relationship between the initial impact of a wildfire on residents of two rural communities in British Columbia (3.5 years prior), their current perceptions of attachment to their community, and their current symptoms of depression. The 2003 McLure Wildfire provides the context for the present exploratory study. I employed a cross-sectional survey design. A sample of 104 male and female residents, with an average age of 56 years, was recruited from both Louis Creek and Barriere to complete self-report measures. I developed two instruments for use in the present study; one assessed the initial impact of the wildfire and the other perceptions of current place attachment. Factor analyses supported the structural validity of the instruments; three factors represented place attachment dimensions (social, natural, and built environments), and one represented change in attachment. Depressive symptoms were measured using a 10-item short version of the Center for Epidemiologic Studies Depression Scale (Andresen, Malmgren, Carter, & Patrick, 1994). Hierarchical multiple regression (HMR) analyses showed that the greater impact the wildfire had on respondents, the (a) less attached to the built environment they felt, and (b) the greater their symptoms of depression. Furthermore, feeling less attached to the natural environment was related to greater symptoms of depression. Age and marital status were controlled for in HMR analyses predicting attachment and depressive symptoms. Although Louis Creek respondents experienced higher mean levels of impact and depressive symptoms, compared with those from Barriere, once age and/or marital status were controlled for, community differences were not statistically significant. The findings support a multidimensional framework of place attachment. Limitations and implications for further research, including the development of a valid measure of place attachment, are discussed.

Detection of hard X-ray pulsations and a strong iron K_beta emission line during an extended low state of GX 1+4

description: We present here results obtained from a detailed timing and spectral analysis of three BeppoSAX observations of the binary X-ray pulsar GX 1+4 carried out in August 1996, March 1997, and August 2000. In the middle of the August 2000 observation, the source was in a rare low intensity state that lasted for about 30 hours. Though the source does not show pulsations in the soft X-ray band (1.0-5.5 keV) during the extended low state, pulsations are detected in 5.5-10.0 keV energy band of the MECS detector and in hard X-ray energy bands (15-150 keV) of the PDS instrument. Comparing the 2-10 keV flux during this low state with the previously reported low states in GX 1+4, we suggest that the propeller regime in GX 1+4 occurs at a lower mass accretion rate than reported earlier. Broad-band (1.0-150 keV) pulse averaged spectroscopy reveals that the best-fit model comprises of a Comptonized continuum along with an iron K_alpha emission line. A strong iron K_beta emission line is detected for the first time in GX 1+4 during the extended low state of 2000 observation with equivalent width of ~550 eV. The optical depth and temperature of the Comptonizing plasma are found to be identical during the high and low intensity states whereas the hydrogen column density and the temperature of the seed photons are higher during the low state. We also present results from pulse phase resolved spectroscopy during the high and low flux episodes.

description: We present spectroscopic observations of the short-period cataclysmic variable SW Ursa Majoris, obtained by the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite while the system was in quiescence. The data include the resonance lines of O VI at 1031.91 and 1037.61 A. These lines are present in emission, and they exhibit both narrow (~ 150 km/s) and broad (~ 2000 km/s) components. The narrow O VI emission lines exhibit unusual double-peaked and redshifted profiles. We attribute the source of this emission to a cooling flow onto the surface of the white dwarf primary. The broad O VI emission most likely originates in a thin, photoionized surface layer on the accretion disk. We searched for emission from H_2 at 1050 and 1100 A, motivated by the expectation that the bulk of the quiescent accretion disk is in the form of cool, molecular gas. If H_2 is present, then our limits on the fluxes of the H_2 lines are consistent with the presence of a surface layer of atomic H that shields the interior of the disk. These results may indicate that accretion operates primarily in the surface layers of the disk in SW UMa. We also investigate the far-UV continuum of SW UMa and place an upper limit of 15,000 K on the effective temperature of the white dwarf.
