description: Surplus asphaltenes production in northern Alberta facilities, led to searching new pathways to process asphaltenes pitches as the most challenging material in heavy oils. Due to the additional expenses these compounds could cause as a result of precipitation at flow lines, well bore and production separators, the separation of them from heavy oil and potentially extracting valuable products from them is relevant. Oxy cracking asphaltenes in liquid phase under alkali conditions could be a new approach to creating more value from asphaltenes, this is the topic of this research. Asphaltene drops were oxy-solubilized in water with the ultimate intention of reducing their molecular weight, converting them to analogs of humic substances, which could have extensive applications as co-fertilizers for enhancing soil quality and productivity in agriculture and many other industrial new applications as photo-sensibilizers for solar cell panels. The intention is to convert these organic materials via a low energy requiring mechanism into intermediate simpler oxidized-organic compounds minimizing secondary end products like carbon oxides. For this purpose, the optimum operating conditions, reaction kinetics and depiction of reaction mechanism were researched for C5 precipitated asphaltenes during oxy-cracking in batch mode. A model based on sequential-parallel reactions from the asphaltenes to water-soluble products and CO2 was found to describe the process adequately. The results showed that by introducing oxygen onto asphaltenes at moderate temperatures (180 °C-225 °C) and pressures (300-500 psi) in liquid phase, asphaltenes oxy-cracked to humic and fulvic analogs and under more severe reaction conditions, most of the humic analogs converted to fulvic analogs having lower molecular weight in comparison with humic analogs. Afterward, a continuous bench scale set up was conceptualized, built and tested based on batch experiments to evaluate the continuous oxy-cracking of asphaltenes in water. Comprehensive characterization analysis was carried out on asphaltenes oxy-cracking products in batch and continuous mode to understand the chemical structure of products. Production of oxidized functionalities like carboxylic acids, their salts, methyl ethers and esters, sulfur-oxidized forms plus phenolics, were determined as the most significant fractions soluble in water. Upstream solubilization and industrialization of derivatives of asphaltenes in water before the crude oils are mobilized throughout the commercialization chain could also decrease challenges regarding facilities and pipelines plugging.

description: In this talk I will present some of the main difficulties we encounter in studying the large scale behavior of disordered systems. This presentation will be done using a field theory language. The difficulties in applying the standard renormalization group approach are due to the presence of strong non-perturbative effects that we do not know how to master. These difficulties are particular acute in the case of ferromagnets in random field, localized electrons, growth models and spin glasses. I will review the situation presenting at the end a promising approach based on fat diagrams.

description: Traumatic joint injuries resulting in the rupture of the anterior cruciate ligament (ACL) are common in pivoting sports such as hockey, football and soccer. To prevent further joint injury, the current gold standard of treatment calls for the timely surgical reconstruction of the ruptured ACL to return stability to the injured joint. For reasons that are currently unknown, a significant number of surgically treated patients will develop post-traumatic osteoarthritis (PTOA). It is possible that the surgery itself may be a traumatic joint injury that results in the development of PTOA. Two separate animal models were designed to study both the biological and kinematic mechanisms that may contribute to the development of PTOA after ACL reconstructive surgery. An ovine model of idealized ACL reconstruction (ACL-R) was used to investigate alterations to the joint kinematics and biological responses within key joint tissues after surgery. A rabbit drill injury model was used to solely investigate the early biological changes within the knee, by limiting the impact on biomechanical aspects as much as possible. Within ACL-R joints, PTOA-like changes occur early and appear to result from predominantly biological mechanisms. Despite maintaining joint kinematics that were comparable to those of control animals, it was found that ACL-R surgery results in gross morphological PTOA-like changes at 20 weeks post-surgery. Within ACL-R joints, the initial inflammatory response appears to be early, returning to levels comparable to those of control animals by 20 weeks post- surgery, suggesting that an anti-inflammatory treatment administered early after injury may prevent PTOA-like changes from occurring. Mitigating the surgery associated inflammation in the rabbit drill injury model with a single post-surgical intraarticular (IA) injection of dexamethasone (DEX) significantly reduced PTOA- like changes at 9 weeks post-surgery. The single IA DEX injection significantly limited the inflammatory response and activation of MMP 3 within the synovium and infrapatellar fat pad at 48 hours post-surgery, resulting in cartilage that is less susceptible to structural damage due to preserved proteoglycan content in the cartilage at 9 weeks post-surgery.

description: Nano-scale particles due to their outstanding ability to improve physico-mechanical properties of polymeric matrices have been the major research interest in composite science area in recent years. In many cases the so-called improved properties are considered to be linked to the irreversible particle aggregation, leading to formation of fractal clusters which eventually coalesce and constitute a sample-spanning network structure. If not masked by dispersing medium elasticity, self-similar, fractal nanoparticle superstructure imparts solid-like behavior to the long-time response of a wide variety of complex fluids. The main focus of this PhD dissertation is distinguishing the main parameters affecting particle-particle and polymer-particle interactions and using this knowledge to develop nanocomposites with improved dispersion-states and properties. Nanofillers such as undoped and nitrogen-doped multi-walled carbon nanotubes (MWCNTs) and organically modified clays as well as more recently developed nanofillers such as graphene nanoribbons (GNRs) were employed for this purpose. In this context, the effect of polymer matrix molecular features was also taken in to the account. Results of this work proved the importance of polymer matrix relaxation time distribution and how it can be used to detect solid-like behavior via rheological technique. It was also demonstrated that linear and nonlinear melt-state rheological responses of nanocomposites would be significantly impacted by nanofiller surface chemistry. Observed differences were explained by the inhomogeneity of surface charge density distribution and suppressed short-range interactions in presence of surface functionalities. As a consequence, short-range interactions become dependent on particle-particle orientation-state leading to significant changes in the dispersion-state and the viscoelastic and thixotropic behavior of the polymer nanocomposites. Geometrical features of nanofillers were also found to play a major role in shaping the solid-like behavior. It was found that well-dispersed ribbon-like nanofillers (GNR) formed a network structure activated by formation of primary and secondary entanglements between adsorbed polymer chains and bulk polymer chains. However, tube-like nanofiller (MWCNT) presented a strongly flocculated network structure formed through the direct tube-tube contact and mechanical entanglements. This seemingly inferior characteristic of nanoribbons has been utilized as an advantage to develop hybridized nanocomposite systems for charge storage applications.

description: We solve the wave equations of arbitrary integer spin fields in the BTZ black hole background and obtain exact expressions for their quasinormal modes. We show that these quasinormal modes precisely agree with the location of the poles of the corresponding two point function in the dual conformal field theory as predicted by the AdS/CFT correspondence. We then use these quasinormal modes to construct the one-loop determinant of the higher spin field in the thermal BTZ background. This is shown to agree with that obtained from the corresponding heat kernel constructed recently by group theoretic methods.

description: We present an analysis of the Hubble Space Telescope/Space Telescope Imaging Spectrograph (HST/STIS) far ultraviolet snapshot spectrum of the dwarf nova BZ UMa taken during quiescence. We find that the flux continuum is consistent with that of a white dwarf atmosphere with a temperature of 15,000K, and a distance of about 156pc when assuming a white dwarf gravity of log(g)=7.5. We also show that the hydrogen quasi-molecular satellite lines opacity affects the spectrum around 1300-1400 A and has to be included to fine-tune the spectral modeling, this is self-consistent with the low stellar temperature we find.

A multi-dimensional approach to the study of online annotation
Creators: name: Chiang, Chia-Ning
Publisher: name: University of British Columbia

description: Digital annotations share the purpose and nature of traditional paper annotations when reading online. Annotation form represents the behavior associated with completing an annotation. Annotation function reflects the users’ cognitive states while annotating. The role indicates the intended audience (private, work group, and larger public) for the annotation, and provides an opportunity to investigate the functions of annotation in its social setting. Perceived values indicate the acceptance of annotation online. A broader understanding of what forms facilitate the creation of an individual’s online annotation while reading, as well as the co-relation of the form, function, and role of annotation when reading online is needed. Furthermore, evaluations of the perceived values of online reading and writing that constitute the acceptance of annotation online are also critical. This research employs a mixed-method approach for studying annotation online. Using an annotation prototype plugged into the Open Journal Systems, 15 participants conducted three reading tasks. The findings from the main study (user think-aloud protocol and interview transcripts) and supplementary information (post-session questionnaire and perceived value questionnaire) are analyzed according to the six research questions. Furthermore, a review of existing annotation tools and literature are used as an explanatory component for comparing and contrasting the findings of main study. The findings show that some online annotation forms take advantage of the change capability in visual styles of interface design and the network environment of the community, which have no counterpart in the print environment. Findings of online annotation functions are grounded in visual foraging of information and the theory of text signaling. In addition, annotation forms in combination with types of text annotated (e.g., headings) and text structures (e.g., topic sentence) result in the manifestation of different functions. Furthermore, role-attached social forms also function the same as “signals” for sharing or communication. It is also observed that annotation functions shift in different reading tasks. In general, people consider online annotation very useful, and improvements in performance, effectiveness, and utility of annotation while reading online, as well as the ease with which the skill is acquired, account for this acceptance.

description: Our comprehension of stellar evolution on the AGB still faces many difficulties. To improve on this, a quantified understanding of large-amplitude pulsator atmospheres and interpretation in terms of their fundamental stellar parameters are essential. We wish to evaluate the effectiveness of the recently released CODEX dynamical model atmospheres in representing M-type Mira variables through a confrontation with the time-resolved spectro-photometric and interferometric PTI data set of TU And. We calibrated the interferometric K-band time series to high precision. This results in 50 nights of observations, covering 8 subsequent pulsation cycles. At each phase, the flux at 2.2$μ$m is obtained, along with the spectral shape and visibility points in 5 channels across the K-band. We compared the data set to the relevant dynamical, self-excited CODEX models. Both spectrum and visibilities are consistently reproduced at visual minimum phases. Near maximum, our observations show that the current models predict a photosphere that is too compact and hot, and we find that the extended atmosphere lacks H2O opacity. Since coverage in model parameter space is currently poor, more models are needed to make firm conclusions on the cause of the discrepancies. We argue that for TU And, the discrepancy could be lifted by adopting a lower value of the mixing length parameter combined with an increase in the stellar mass and/or a decrease in metallicity, but this requires the release of an extended model grid.

description: Research on the inorganic carbon cycle in the Arctic winter to spring transition process has revealed that ice algae could play a role in the inorganic carbon cycling under sea ice. A ten-week case study was conducted near Qikiqtarjuaq, NU, Canada, in which dissolved inorganic carbon (DIC) and was collected from the water column. Samples were collected near the start of an ice algae bloom, and continued until early stages of an under-ice phytoplankton bloom. During the ice algae bloom period, there was no significant decrease in DIC or pCO2sw prior to sea ice melt. DIC fixation calculations show that previous studies may have overestimated the drawdown of DIC from ice algae, but that sloughing ice algae or an under-ice phytoplankton bloom can dramatically reduce DIC and pCO2sw. This case study provided insights that under-ice phytoplankton blooms are a more important biological mechanism preconditioning the Arctic surface mixed layer.
Molecular dynamics study of nanoscale heat transfer at liquid-solid interfaces (LSIs)

description: Phonons, or lattice vibrations, are the primary thermal energy carriers in dielectric solids. At liquid-solid interfaces (LSIs), there is a considerable mismatch in the vibrational properties between the two phases. Consequently, during heat transfer across LSIs, the transmission of phonons is impeded. This gives rise to a temperature drop that is proportional to what is termed as the Kapitza resistance(RLSI). The present work examines various important aspects of nanoscale heat transfer across LSIs. This is accomplished computationally using the Molecular Dynamics (MD) method, in which the two phases are treated at the atomic scale. First, the effect of the solid surface geometry is investigated in light of advancements in nanopatterning. It is found that the surface atomic structure can be tailored to significantly reduce RLSI, by simultaneously influencing two key factors: (i) the interaction energy between liquid and solid atoms at the LSI, and (ii) the vibrational characteristics of the nanopatterned surfaces. The second study focuses on the effects of system pressure on RLSI for wetting (W), and nonwetting (NW) surfaces, respectively. It is demonstrated that, in contrast to the W surfaces, the system pressure has a strong effect on lowering RLSI for the NW surfaces. For the pressure range considered, it is concluded that the central cause of this behavior is the relative increase in adsorbed liquid density accompanying the pressure increase. In the third part of the thesis, the aim is shifted towards carbon nanotubes (CNTs). Using a novel technique, a spectral analysis for the frequency dependence of thermal energy exchange at CNT LSIs is conducted. The results confirm the notion of thermal coupling between a CNT and its surrounding liquid being limited to the low frequency range. The CNT inner high-to-low frequency heat transfer is a limiting factor that results in a high RLSI. More importantly, the findings provide evidence of the origin of a heat transfer 'bottle-neck' within the CNT. This could provide new avenues for improving RLSI in CNTs.

description: This thesis examines the historical legacies of Poland’s partitioned past as an explanation for contemporary regional differentiation in citizens’ democratic participation. Specifically, it considers the historical experience of the Poles prior to 1919 and their response to the occupying powers of Austria, Prussia, and Russia following the partition of the state between 1772 and 1795. In doing so, it focuses on two mechanisms: the birth of modern cultural nationalism and peasant political integration. It argues that the way these variables developed under the authority of the occupying powers accounts for a) the quality of contemporary democratic participation, and b) the persistence of political values over time. The Polish example illustrates the larger implications of the preconditions driving citizen participation and how these affect the quality of democratic development.

description: We present transmission spectra of the hot Jupiter HD 189733b taken with the Space Telescope Imaging Spectrograph aboard HST. The spectra cover the wavelength range 5808-6380 Ang with a resolving power of R=5000. We detect absorption from the NaI doublet within the exoplanet's atmosphere at the 9 sigma confidence level within a 5 Ang band (absorption depth 0.09 +/- 0.01%) and use the data to measure the doublet's spectral absorption profile. We detect only the narrow cores of the doublet. The narrowness of the feature could be due to an obscuring high-altitude haze of an unknown composition or a significantly sub-solar NaI abundance hiding the line wings beneath a H2 Rayleigh signature. We compare the spectral absorption profile over 5.5 scale heights with model spectral absorption profiles and constrain the temperature at different atmospheric regions, allowing us to construct a vertical temperature profile. We identify two temperature regimes; a 1280 +/- 240 K region derived from the NaI doublet line wings corresponding to altitudes below ~ 500 km, and a 2800 +/- 400 K region derived from the NaI doublet line cores corresponding to altitudes from ~ 500-4000 km. The zero altitude is defined by the white-light radius of Rp/Rstar=0.15628 +/- 0.00009. The temperature rises with altitude, which is likely evidence of a thermosphere. The absolute pressure scale depends on the species responsible for the Rayleigh signature and its abundance. We discuss a plausible scenario for this species, a high-altitude silicate haze, and the atmospheric temperature-pressure profile that results. In this case, the high altitude temperature rise for HD 189733b occurs at pressures of 10^-5 to 10^-8 bar.

The carapace of the first stage crab (0.88–0.96 mm SL) has a V-shaped longitudinal whitish band (Fig. 3 A, B). The pleon has a longitudinal whitish stripe along the middle portion and transverse whitish stripes on the portion containing the future tergal plates. The gastric and intestinal portions with a brownish content are visible under the semitransparent carapace and pleon; this feature can be observed in first stage crabs of all species.
The shield of the first stage crab has faint small brownish pigments; they develop into two brownish patches at the anterior one-third of the animal and a brownish band extending from the middle margin through each side wall of the whitish/creamy shield in juveniles that have an SL of> 1 mm after one month of age (Fig. 3 A–G, 4A–E). The shield of some individuals has a longitudinal brownish stripe at the mid-posterior portion (Fig. 3 E, 4A, D, E). The second and third pereiopods of the first stage crabs are reddish (Fig. 3 A). After one month of age, the pereiopods generally exhibit a whitish/creamy color, and the palm of the left cheliped (the first pereiopod) develops two longitudinal brownish bands on the middle and upper portions; the propodi and carpi of the second and third pereiopods have longitudinal brownish stripes on the upper and/or lower margins; the dactyli and meri of the pereiopods become brownish (Fig. 3 C, E, G, 4A, C–E). The brownish color of the body parts gradually changes to purplish after nine months of age (Fig. 4 A, C–E); purplish color of the specimens was not different from that of the live crab (Fig. 4 D, E).

description: O regime audiovisual da União Europeia tem como objetivo primordial prosseguir a liberdade de circulação de serviços da comunicação audiovisual. Constituem traves mestras do ordenamento jurídico europeu, da política europeia e da construção do mercado único: (i) o princípio do estado de origem, (ii) o princípio da jurisdição exclusiva e, obviamente, (iii) o princípio da liberdade de circulação de serviços Emissões televisivas destinadas a um país diferente do país de origem são uma realidade incontornável e replicada em todo o espaço europeu. A jurisdição de um Estado sobre um serviço de programas televisivos é condição essencial para aplicação das «suas» normas nacionais, balizadas pelas regras comunitárias, a esse mesmo serviço de programas. A existência de serviços de programas «estabelecidos» num determinado Estado da União Europeia, mas que dirigem a sua programação, exclusiva ou maioritariamente, para outro Estado membro, com legendagem e com conteúdo publicitário especifico, constitui uma prática recorrente. Os operadores sediados num determinado Estado membro onde a legislação nacional, que transpõe a Diretiva de Serviços de Comunicação Social Audiovisual (DSCSA), é aplicada e o seu cumprimento ou incumprimento regularmente auditado, designadamente no que diz respeito ao apuramento das quotas de conteúdos, poderão sentir-se «discriminados» ao ter um concorrente para o mesmo mercado que não é alvo do mesmo escrutínio efetuado no «seu» Estado membro. Existem exceções à liberdade de prestações de serviços audiovisuais. Mas também aqui se colocam questões complexas, designadamente no que diz respeito à aplicação destas cláusulas de salvaguarda. Quando adotar e como concretizar os mecanismos de «defesa» previstos na DSCSA para serviços de programas fornecidos por operadores de televisão sob jurisdição de outro Estado membro sempre que se verifique que tais serviços são total ou principalmente dirigidos a outro território? O que deve ser considerado infração, o que são regras mais rigorosas e o que se deve entender como medidas adequadas, necessárias e proporcionais?

Developing trust reciprocity in e-government : the role of felt trust

description: Citizens’ levels of trust in e-government, has been proposed as an important impediment to increased utilization of e-government. Although there is a large amount of literature on online trust, no study to date has examined the impact of felt trust - a person’s feeling of being trusted - on the adoption of electronic business in general, or online government services in particular. No study has examined how IT artifacts on websites make citizens feel that they are trusted by the government, and how that “felt trust” could affect citizens’ trust in websites and, subsequently, users’ adoption of these websites. This “felt trust” construct, which is new to the IS literature, has received the attention of scholars in other disciplines; their empirical works, framed in theories such as Social Exchange Theory, Leader-Member Exchange Theory, and Appropriateness Framework, have shown that perceptions of felt trust lead to trust-related behaviour and other considerations (e.g., satisfaction and loyalty). A series of qualitative studies, were conducted to identify the antecedents of trust and felt trust. Next, a model of e-government adoption was tested using data collected from 254 participants in an online survey. Felt trust was found to be the most important factor in building trust, and trust fully mediated felt trust’s impact on the antecedents of adoption (i.e., perceived usefulness, perceived ease of use and perceived risk). The convergent and discriminant validities demonstrated not only the difference between felt trust and trust as constructs, but also the difference between these constructs in both online and offline environments. The Information Systems research community should focus more on the construct of felt trust by investigating its influence on other outcome variables such as satisfaction with trustees (e.g. e-vendors), the productivity of virtual teams, and success of outsourcing relationships. Existing IS research findings can also be re-evaluated in light of the importance of this new construct to determine whether existing IT artifacts used or systems implemented to build trust were successful, not because they improved trust directly, but because they triggered felt trust, which, in turn, improved trust.

description: The diagnostic criteria for Autism Spectrum Disorder (ASD) cluster around communicative, linguistic, and social deficits (DSM-IV; American Psychiatric Association, 1994). Identification of impairments associated with ASD relies on children’s explicit behaviours, which only emerge reliably after the first year of life (De Giacomo & Fombonne, 1998). Thus, data on earlier social attention, language development, and ASD behaviours in children with ASD are limited. In this dissertation, I examine how early perceptual biases and ASD-like behaviours relate to language skills in a high-risk cohort of infant siblings of children with ASD (SIBS-A) and a low-risk cohort of infants siblings of typically developing children (SIBS-TD). Chapter 2 investigates whether biases to infant-directed (ID) speech and faces differ between SIBS-A and infant siblings of typically developing children (SIBS-TD), and to what extent early differences may be predictive of language skills and risk group membership. In this study, we found that both infant groups preferred ID to adult-directed (AD) speech and preferred faces to checkerboards; however, the magnitude of the preference was smaller in SIBS-A. SIBS-TD demonstrated higher expressive vocabulary than SIBS-A at 18 months. Vocabulary size correlated with early speech preferences, suggesting that a preference for ID speech early in development may facilitate later expressive language. Finally, infants’ preference for faces contributed to determining group membership. Chapter 3 explores vocabulary development and ASD-related behaviours, and whether these skills are associated with one another and differ between high-risk and typically developing infants. Results from this study demonstrated that SIBS-A exhibited lower expressive vocabulary at 12 and 18 months as compared with SIBS-TD. SIBS-A additionally demonstrated significantly more ASD-like behaviours that were also more severe in nature at 18 months. Moreover, expressive and receptive vocabularies were significantly correlated with ASD behaviours. The findings of these studies suggest that infants at heightened risk of ASD differ from SIBS-TD in their preferences for ID speech and faces, as well as vocabulary skills and ASD behaviours early in childhood. These early linguistic and behavioural differences may underlie deficits in later language development and social communication and have important implications for research examining early detection measures for ASD.

description: A comunicação tem por objeto a análise do tema da privatização da RTP como estratégia de Comunicação Política, no período compreendido entre finais de 1997, altura em que Marcelo Rebelo de Sousa, então líder do PSD, sugeriu propor a privatização da RTP, e o primeiro semestre de 2013, momento em que o XIX Governo Constitucional decidiu suspender o então anunciado processo de privatização da RTP. A partir de um conjunto de dados secundários, designadamente, a imprensa escrita, comunicados oficiais e o arquivo da Assembleia da República, procurou-se alcançar respostas para as seguintes interrogações: Em que contexto é que o tema da privatização da RTP (re) surge continuamente ao longo do tempo? Quais são os elementos centrais da narrativa política em prol, ou contra, a ideia de privatização da RTP? Existe, ou não, um antagonismo ideológico entre o pensamento político de esquerda e o de direita relativamente ao tema da privatização da RTP? Como resultado da investigação concluímos que a comunicação política em torno da ideia da privatização da RTP é utilizada como estratégia simbólica de afirmação política. A discussão em torno da RTP assume uma natureza simbólica, mobilizadora de outros significados, designadamente, de opções ideológicas sobre o papel do Estado na sociedade e na economia.
