description: This thesis describes three investigations of basic principles in biology using the nematode C. elegans. It is centered on two general features of biology, cell to cell communication and the activation or inactivation of genes within an organ. In the first study, I examined the role of a conserved TGF-β signaling pathway in body size regulation. This signaling pathway is active in three organs of C. elegans; the pharynx, hypodermis and intestine. Previous research had concluded that signaling in the hypodermis was necessary and sufficient to regulate body size of C. elegans. My results demonstrated two key findings that modify the model of body size regulation. One, that this signaling pathway regulates size of the pharyngeal organ and two, that pharyngeal signaling can contribute in a minor way to overall body size regulation. These results suggest that TGF-β signaling in C. elegans could be coordinating growth of many cells. The second and third studies dealt with transcriptional regulation of terminal gene expression within the intestine. A hierarchy of GATA transcription factors work to specify the intestinal precursor during embryogenesis and mediate intestinal differentiation. Once embryogenesis is complete, two GATA factors, ELT-2 and ELT-7 function to regulate expression of terminal intestinal genes. These two factors are present at apparently equal levels in all intestinal cells, yet some intestinal genes are only expressed in a subset of these cells. The second project explored what other transcription factors are restricting expression of the pho-1 gene to the posterior intestine. The results from repeating work of a previous student revealed the novel finding that pho-1 expression is initially found in the anterior intestinal cells, then becomes restricted by the end of the first larval stage. It was confirmed that the heterochronic gene lin-14 is repressing anterior pho-1 expression, but not by a direct mechanism. The final project was an exploration of the intestinal targets of ELT-2 and ELT-7. RNAseq results indicate ELT-2 is the primary regulatory of gene expression in the intestine, with ELT-7 functioning partially redundantly. Furthermore, genes regulated by both factors were found to have more cis-regulatory elements in their promoters. In summary, these projects have furthered understanding of two conserved features of eukaryote biology, TGF-β signaling in growth regulation and GATA transcriptional regulation in the endoderm.

description: Research in student knowledge and learning of science has typically focused on explaining conceptual change. Recent research, however, documents the great degree to which student thinking is dynamic and context-sensitive, implicitly calling for explanations not only of change but also of stability. In other words: When a pattern of student reasoning is sustained in specific moments and settings, what mechanisms contribute to sustaining it? We characterize student understanding and behavior in terms of multiple local coherences in that they may be variable yet still exhibit local stabilities. We attribute stability in local conceptual coherences to real-time activities that sustain these coherences. For example, particular conceptual understandings may be stabilized by the linguistic features of a worksheet question, or by feedback from the students' spatial arrangement and orientation. We document a group of university students who engage in multiple local conceptual coherences while thinking about motion during a collaborative learning activity. As the students shift their thinking several times, we describe mechanisms that may contribute to local stability of their reasoning and behavior.

description: Entry into post-secondary studies from high school presents students with an assortment of challenges that extend far beyond conventional academic demands. These students are often required to modify their orientations to learning, foster, and maintain new social support networks, manage complex responsibilities, regulate personal freedoms, and navigate the many environmental and psychological stressors that will likely appear along the way. In the empirical literature, there is consensus that high school grade point average (HSGPA) represents the best predictor of success during this time of transition. Although HSGPA is often used to screen for entrance into higher education, little is known as to how or why it facilitates positive adjustment. Some have argued that HSGPA is influential because it is represents an interaction of internal and external factors. The purpose of this study was to undertake an empirical investigation to determine whether academic resilience, as defined by specific traits found within students that help them overcome situational adversity to achieve academically, mediates the relation between HSGPA and post-secondary success (i.e., achievement and retention outcomes). Using structural equation modeling, the responses from 655 first-year undergraduate participants were examined and demonstrated positive findings. Specifically, academic resilience accounted for approximately 5% of shared variance between HSGPA and post-secondary academic achievement. Due to the limited number of students who identified themselves as leaving academic studies, the mediational properties of academic resilience could not be explored within the context of post-secondary retention. The limitations of this study and future directions are discussed in relation to the obtained results.

description: We present and characterize a laser system for the spectroscopy on highly-charged ^209Bi^82+ ions at a wavelength of 243.87 nm. For absolute frequency stabilization, the laser system is locked to a near-infra-red laser stabilized to a rubidium transition line using a transfer cavity based locking scheme. Tuning of the output frequency with high precision is achieved via a tunable rf offset lock. A sample-and-hold technique gives an extended tuning range of several THz in the UV. This scheme is universally applicable to the stabilization of laser systems at wavelengths not directly accessible to atomic or molecular resonances. We determine the frequency accuracy of the laser system using Doppler-free absorption spectroscopy of Te_2 vapour at 488 nm. Scaled to the target wavelength of 244 nm, we achieve a frequency uncertainty of σ_{244nm} = 6.14 MHz (one standard deviation) over six days of operation.

description: Technology is an element of human life worthy of reflection, from the apparent proliferation of technological use in society to the rapid changes in the way we connect and relate to each other through technology. Contemporary ways of thinking about knowledge and work suggest that teachers have been challenged to entertain new and emerging technology in their classrooms. The primary intent of this descriptive case study was to develop an experiential understanding of how teachers might make sense of new and emerging (unfamiliar) technology as a process. The study explored two main questions: 1) How do teachers make sense of new and emerging technology to enhance teaching and learning? 2) How might these teachers’ insights inform strategies to support the implementation of a new technology in teaching and learning? A framework of enablers was constructed to make sense of the complexity of teacher experience with unfamiliar technology to support the process of meaningful learning. Key findings provide practical knowledge and suggestions to support teachers with the implementation of unfamiliar technology in teaching and learning. Teachers must be willing to learn with technology and their capacity to grapple with or even entertain the unfamiliar will benefit from a collection of external affordances. If society wants teachers to grapple with new and emerging technology, teachers need some sort of supportive system with opportunities to better understand and address technological constraints. The lesson learned is that one size will not fit all when looking to bolster teacher capacity. Teachers will benefit from participating in building personal pathways for sense making of new and emerging technology.

Distribution. Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden, Russian Fennoscandia.—Transpalearctic: from West Europe to Mongolia (Linsenmaier 1997).
Remarks. The species is known from all the Nordic and Baltic countries, but it is usually uncommon and found in low numbers. The northernmost records are from northern Sweden. In Finland it has declined and has been classified as near threatened (Paukkunen 2010). Soon (2004: 46) reported C. pseudobrevitarsis from Norway and Denmark, but later the record from Norway proved to be erroneous. However, one specimen was recently found from southern Norway (Farsund) and the determination was confirmed by DNA barcoding. Records from Denmark are based on two specimens in ZMUC, which were collected from Bornholm and Zealand (see data above).
According to mitochondrial DNA studies, the species is divided into two genetically distinct lineages, both of which have been found from the Nordic and Baltic countries (Soon et al. 2014). The other lineage is closer to C. brevitarsis, making C. pseudobrevitarsis paraphyletic, and therefore the lineages could represent different species. The morphological differences and nomenclature of these two lineages remain to be determined.

description: Vitamin D plays an important role in promoting healthy pregnancy and fetal development. There is a lack of knowledge on (1) the effect of vitamin D deficiency/ insufficiency on pregnancy and neonatal outcomes, (2) the association between maternal plasma vitamin D concentration and dietary intake, and (3) the prevalence of vitamin D deficiency/ insufficiency during pregnancy and the contribution of vitamin D metabolites to estimate vitamin D. This dissertation attempts to address these knowledge gaps about vitamin D during pregnancy. In a systematic review and meta-analysis of observational studies, low maternal 25(OH)D concentrations were found to be associated with higher risks of gestational diabetes (pooled OR 1.49, 95% CI: 1.18 to 1.89), preeclampsia (pooled OR 1.79, 95% CI: 1.25 to 2.58), small for gestational age (SGA) (pooled OR 1.85, 95% CI: 1.52 to 2.26) and lower birth weight (weighted mean difference: -130.92 g (95% CI: -186.69 to -75.14). However, that quality of individual studies was not always optimal due to inconsistent reporting on confounding factors. The two studies in this work involved pregnant women from a large Alberta cohort study to measure vitamin D. 3-epi-25(OH)D3 was found in all of the pregnant women’s blood in mid-pregnancy, at the time of delivery and in cord blood. When the 3-epimer was included in the estimation of status, the prevalence of vitamin D <75 nmol/L was significantly lower (P<0.005). A significant relationship between maternal reported dietary vitamin D intake and plasma 25(OH)D and 3-epi-25(OH)D3 concentration were identified. Consuming the Recommended Dietary Allowance (RDA) (600 IU/ day) was found to be insufficient to achieve vitamin D <75 nmol/L in half of participants. This research highlighted the potentially important association between maternal vitamin D status and pregnancy health and the variability that can arise in study results when different measures of vitamin D status are used. In addition, it extends the literature suggesting that current RDA may not be adequate to ensure that Canadian pregnant women achieving vitamin D status. Furthermore, this research showed that the method employed to measure vitamin D in pregnant women and cord blood can influence the estimates of status.

description: Transport properties of the two-orbital Kondo effect involving both spin and orbital (pseudospin) degrees of freedom were examined in a parallel double quantum dot with a sufficient interdot Coulomb interaction and negligibly small interdot tunneling. The Kondo effect was observed at the interdot Coulomb blockade region with degeneracies of both spin and orbital degrees of freedom. When the orbital degeneracy is lifted by applying a finite detuning, the Kondo resonance exhibits a triple-peak structure, indicating that both spin and orbital contributions are involved.

Measuring confidence with manual wheelchair use : a four phase, mixed-methods study
Creators: name: Rushton, Paula Wendy
Publisher: name: University of British Columbia
Year: 2011

description: Introduction Confidence in one’s ability to perform a given task can be a stronger predictor of performance than skill itself. There are currently no measures to assess confidence with manual wheelchair use. The objective of this study was to develop and assess the psychometric properties of a new outcome measure, the Wheelchair Use Confidence Scale (WheelCon-M). Purpose 1. To describe situations that challenge confidence with manual wheelchair use from the perspectives of wheelchair users and health care professionals (chapter 2). 2. To select items and assess the test content of the WheelCon-M (chapter 3). 3. To refine items on the WheelCon-M to ensure each item is interpreted as intended (chapter 4). 4. To examine the psychometric properties of the WheelCon-M (internal structure, internal consistency, reliability, and relations to other variables) (chapter 5). Methods Design: This study used a mixed-methods design incorporating qualitative interviews (chapter 2), a Delphi survey (chapter 3), a think aloud process (chapter 4), and a test-retest methodological study (chapter 5). Participants: Wheelchair users participated in the interviews (n=13), Delphi survey (n= 22), think aloud process (n=7), and test-retest (n=83). Health care professionals participated in the interviews (n=16) and the Delphi survey (n=16). Researchers participated in the Delphi survey (n=5). Measures: A semi-structured interview guide was used for the qualitative interviews (chapter 2) and standardized measures were used in the test-retest study (chapter 5), including the Wheelchair Skills Test, version 4.1 (objective and questionnaire versions), Barthel Index, Life Space Assessment, Interpersonal Support Evaluation List, Hospital Anxiety and Depression Scale, Functioning Everyday with a Wheelchair, and a demographic questionnaire. Results The WheelCon-M, version 1.0 was an 84-item scale with items generated from the qualitative interviews. Items were selected and the content validated using the Delphi survey, thus reducing the number of items to 62 (version 2.0). Items were refined using the think aloud process which resulted in a 63-item scale (version 2.1). Support for the psychometrics of the WheelCon-M, version 2.1 was provided in the test-retest study. Conclusions The WheelCon-M, version 2.1 provides a means of measuring confidence with manual wheelchair use from a clinical and research perspective.

description: We study systems with a crossover parameter lambda, such as the temperature T, which has a threshold value lambda* across which the correlation function changes from exhibiting fixed wavelength (or time period) modulations to continuously varying modulation lengths (or times). We report on a new exponent, nuL, characterizing the universal nature of this crossover. These exponents, similar to standard correlation length exponents, are obtained from motion of the poles of the momentum (or frequency) space correlation functions in the complex k-plane (or omega-plane) as the parameter lambda is varied. Near the crossover, the characteristic modulation wave-vector KR on the variable modulation length "phase" is related to that on the fixed modulation length side, q via |KR-q|\propto|T-T*|^{nuL}. We find, in general, that nuL=1/2. In some special instances, nuL may attain other rational values. We extend this result to general problems in which the eigenvalue of an operator or a pole characterizing general response functions may attain a constant real (or imaginary) part beyond a particular threshold value, lambda*. We discuss extensions of this result to multiple other arenas. These include the ANNNI model. By extending our considerations, we comment on relations pertaining not only to the modulation lengths (or times) but also to the standard correlation lengths (or times). We introduce the notion of a Josephson timescale. We comment on the presence of "chaotic" modulations in "soft-spin" and other systems. These relate to glass type features. We discuss applications to Fermi systems - with particular application to metal to band insulator transitions, change of Fermi surface topology, divergent effective masses, Dirac systems, and topological insulators. Both regular periodic and glassy (and spatially chaotic behavior) may be found in strongly correlated electronic systems.

description: Cognitive theories propose that individuals who experience depression may have a latent vulnerability activated during stress that predisposes them to depression (Gotlib & Joormann, 2010). Previous studies found that dysphoric individuals exhibit a negative bias in their attention, attending to negative stimuli more than never depressed individuals and to positive stimuli less (e.g., Arndt et al., 2014). Few studies have examined attention in remitted depressed individuals. The present study examined attentional biases in never depressed, remitted depressed, and dysphoric women using eye-gaze tracking. Participants experienced either a neutral or sad mood induction (MI) and then their attention to images was recorded. There were no group differences in response to the sad MI; never depressed and remitted depressed women who received the sad MI increased their attention to positive images and decreased their attention to threat-related images. The absence of group differences between never depressed and remitted depressed are discussed.

description: Aging public infrastructure asset requires new solutions to address the associated risks in terms of potential failure and poor environmental compliance. Two issues are paramount in looking at the aging infrastructure asset that Calgary Fire Department manages: what is the present condition and how to optimally allocate public funds for its asset needs, specifically preventive maintenance. Asset owners must allocate such limited budgets among competing alternatives, which makes the situation challenging. Among the competing alternatives, preventive maintenance has presented a series of challenges to asset stewards for public infrastructure asset management, especially within municipal government. For Calgary Fire Department (CFD), asset management professionals from Infrastructure Planning and other divisions have made a significant progress in order to achieve "the best possible service", such as Star Quality Rating, risk register, option analysis, existing station retro-commissioning, and Asset Management Plan etc. However, CFD is no exception as other Business Units within The City of Calgary: there are several obstacles stand in the way for asset management practice, specifically capital preventive maintenance expenditures. Nonetheless, with the Five-Step process: Education, Challenge, Environment, Strategy, Delivery (Carroll et al., 2004), there is a great potential to overcome such obstacles.

description: Dependently typed programs contain an excessive amount of static terms which are necessary to please the type checker but irrelevant for computation. To separate static and dynamic code, several static analyses and type systems have been put forward. We consider Pfenning's type theory with irrelevant quantification which is compatible with a type-based notion of equality that respects eta-laws. We extend Pfenning's theory to universes and large eliminations and develop its meta-theory. Subject reduction, normalization and consistency are obtained by a Kripke model over the typed equality judgement. Finally, a type-directed equality algorithm is described whose completeness is proven by a second Kripke model.

description: Introduction: Ongoing improvements in the management of coronary artery disease continue to reduce mortality following myocardial infarction (MI), however, as a consequence the incidence of ischemic heart failure is on the rise. Healthy extracellular matrix (ECM) provides important cues that regulate cell function and survival. Dysregulation of the ECM following MI leads to cardiac fibrosis, left ventricular (LV) dilatation and heart failure. Here we assess whether ECM biology can be leveraged as a therapy to enhance myocardial recovery following MI. Methods and Results: Epicardial Infarct Repair (EIR), a novel bio-surgical procedure where a healthy ECM-biomaterial (CorMatrix®-ECM®, CorMatrix Cardiovascular Inc., GA, USA) is surgically applied to the epicardial surface of the heart post-MI, was evaluated. In a small animal permanent coronary artery ligation model we demonstrate that animals treated with ECM-biomaterial have improved myocardial function and attenuated LV remodeling compared to shams (ejection fraction (EF): 40.5±7.4% vs. 28.7±13.1%, respectively; p<0.001; LV end diastolic volume (LVEDV): 298.0±63.5μL vs. 373.7±78.8μL, respectively; p<0.0001). In order to determine whether this was the result of recovery of the infarcted myocardium or enhanced compensation by the remote myocardium we employed a large animal preclinical ischemia-reperfusion model and evaluated regional cardiac function by MRI demonstrating functional recovery of the infarcted myocardial territory, specifically infarcted myocardium otherwise defined as non-viable with reperfusion alone (change in regional myocardial contraction at 6-weeks: reperfusion+EIR: 28.6±14.0% vs. reperfusion alone: 4.2±13.5% wall thickening; p<0.05). In order to determine whether these structural and functional improvements are the consequence of passive biomechanical restraint or an active bio-inductive mechanism we compared EIR with active ECM-biomaterial versus inactivated (gluteraldehyde-fixed) ECM-biomaterial using our small animal permanent coronary artery ligation model. Animals treated with active ECM-biomaterial demonstrate improved cardiac function and attenuated structural remodeling when compared to inactivated ECM-biomaterial treated animals (EF: 40.5±7.4% vs. 32.7±9.3 %, respectively; p<0.001; LVEDV: 298.0±63.5μL vs. 341.2±48.4 μL, respectively; p<0.0001) as well as evidence of an active bio-inductive mechanism involving vasculogenesis. Conclusion: EIR with ECM-biomaterial attenuates adverse structural remodeling and improves functional recovery following MI through a bio-inductive mechanism involving vasculogenesis, demonstrating that healthy ECM biology can be leveraged to successfully treat MI.
Non-monotonic pressure dependence of the dynamics of soft glass-formers at high compressions

description: In molecular dynamics simulations of soft glass-formers interacting via repulsions, we find that the glass transition temperature, dynamical heterogeneity, and glass fragility reach their maxima at the same crossover pressure $P_d$. Our analysis of the zero-temperature jammed states indicates that states at $P_d$ have the highest bond orientational order with the largest spatial fluctuation. Correspondingly, the low-frequency normal modes of vibration are the least localized and the average potential energy barrier along these modes are the highest for jammed states in the vicinity of $P_d$. The reentrant glass transition and dynamics of supercooled liquids are thus predictable by these structural and vibrational precursors in the zero-temperature jammed states.

description: This study was undertaken to learn more about how mature students perceive the career exploration process when visiting a university career service. Further, research has found that client ratings of the working alliance are a positive predictor of client change; however, this relationship has not been explored in career services. Following Smith and associates (2009) interpretative phenomenological analysis, three mature students were selected and interviewed in order to explore their experiences of engaging in career exploration. They described experiencing a variety of emotions throughout counselling, and a process is suggested about how mature students view their career exploration experiences. The working alliance was an important contribution towards participant experiences and what they identified as helpful and hindering to its development is discussed. This study concludes that the experiences of mature students are unique and that a different career exploration model for mature students may be required.

description: While conodont fossils have been known for over 150 years and have been used extensively for biostratigraphic purposes, it was not until recently that detailed studies of conodont ontogeny and phylogeny have been pursued. While conodonts are widely considered chordates, their exact relationship to living and fossil vertebrates is still debated, while specifics of their ontogeny and life cycle remain largely unexplored. Conodont histology was examined using an array of microscopy techniques, leading to a new three stage ontogeny model while simultaneously building the case for a close phylogenetic relationship to modern day lampreys. In addition to recent paleobiological studies, conodonts have also been increasingly used to obtain paleo-oceanic strontium isotope ratios which can be used for indirect age dating of conodont fossils and the surrounding strata.

description: Nonstandard parafermions are built and their central charges and dimensions are calculated. We then construct new N=2 superconformal field theories by tensoring the parafermions with a free boson. We study the spectrum and modular transformations of these theories. Superstring and heterotic strings in four dimensions are then obtained by tensoring the new superconformal field theories along with some minimal models. The generations and antigenerations are studied. We give an example of the $1^2(5,7)$ theory which is shown to have three net generations.

description: In this paper we analyze the problem of uniqueness for spacelike hypersurfaces with constant higher order mean curvature in generalized Robertson-Walker spacetimes. We consider first the case of compact spacelike hypersurfaces, completing some previous results given in [2]. We next extend these results to the complete noncompact case. In that case, our approach is based on the use of a generalized version of the Omori-Yau maximum principle for trace type differential operators, recently given in [3].

description: We use a perturbative renormalization group approach with short-range continuum model interactions to analyze the competition between isotropic gapped and anisotropic gapless ordered states in bilayer graphene, commenting specifically on the role of exchange and on the importance of spin and valley flavor degeneracy. By comparing the divergences of the corresponding susceptibilities, we conclude that this approach predicts gapped states for flavor numbers N=1,2,4. We also comment briefly on the related gapped states expected in chiral (ABC) trilayer graphene.

Excitation/emission spectroscopy with multi-channel imaging guidance for skin disease diagnosis
Creators: name: Yu, Yingqiu
Publisher: name: University of British Columbia
Year: 2011

description: Skin cancer is the most prevalent type of cancer and early stage diagnosis plays an important role in improving the cure rate. This project is to investigate non-invasive techniques for skin disease diagnosis. Nonlinear Excitation-Emission-Matrix (EEM) spectroscopy is chosen as the core technique in the project, which provides us with biochemical and physiological information for skin tissue characterization. To assist the EEM analysis, multiple imaging channels acquire the image signal in real-time, simultaneously with EEM acquisition. The image-guided EEM provides a more comprehensive set of data containing both biochemical and morphological information of the constituents of skin tissue. A nonlinear EEM system is built by adding a spectroscopy detection path to a multimodality microscopy system. Software programs are custom designed to realize signal synchronization of system components, real-time image acquisition and processing, and EEM measurements. Calibrations and measurements of key parameters are carried out to ensure the accuracy of imaging-guided nonlinear EEM measurements. Preliminary experiments are carried out on purified endogenous skin fluorophores as well as normal and diseased human skin tissue sections. Nonlinear EEMs of normal and seborrheic keratosis skin tissues are compared. Preliminary results from the study demonstrate great potential of using the image-guided nonlinear EEM for skin diseases diagnosis.
Some Puzzles About Ability

description: This thesis aims to solve two metaphysical puzzles about ability. The first belongs to the free will debate: is determinism compatible with the ability to do otherwise? The second pertains to time travel: what things can a backward time traveler do in the past? By introducing two principles about an agent’s ability regarding the past, I defend the following modal principle about ability: what an agent can do must be compossible with the past. This principle generates solutions to the two puzzles.

description: Candidate supernova remnants G23.5+0.1 and G25.5+0.0 were observed by XMM-Newton in the course of a snap-shot survey of plerionic and composite SNRs in the Galactic plane. In the field of G23.5+0.1, we detected an extended source, ~3' in diameter, which we tentatively interpret as a pulsar-wind nebula (PWN) of the middle-aged radio pulsar B1830-08. Our analysis suggests an association between PSR B1830-08 and the surrounding diffuse radio emission. If the radio emission is due to the SNR, then the pulsar must be significantly younger than its characteristic age. Alternatively, the radio emission may come from a relic PWN. In the field of G25.5+0.0, which contains the extended TeV source HESS J1837-069, we detected the recently discovered young high-energy pulsar J1838-0655 embedded in a PWN with extent of 1.3'. We also detected another PWN candidate (AX J1837.3-0652) with an extent of 2' and unabsorbed luminosity L_(2-10 keV) ~ 4 x 10^33 erg/s at d=7 kpc. The third X-ray source, located within the extent of the HESS J1837-069, has a peculiar extended radio counterpart, possibly a radio galaxy with a double nucleus or a microquasar. We did not find any evidence of the SNR emission in the G25.5+0.0 field. We provide detailed multiwavelength analysis and identifications of other field sources and discuss robustness of the G25.5+0.0 and G23.5+0.1 classifications as SNRs. (abstract abridged)

description: Aquest article presenta l’experiència de Gramàtica com parada a l’aula, que constitueix una iniciativa per introduir als llibres de text de llengua catalana de l’educació secundària obligatòria un enfocament de l’ensenyament gramatical a partir de la comparació del català amb altres llengües. Els materials que presentem han estat publicats en els llibres de text Llengua Catalana i Literatura. Construïm de l’editorial Cruïlla, de 1r a 4t d’ESO, en forma d’activitats addicionals a les pàgines dedicades a l’ensenyament de la gramàtica. Es tracta d’un projecte que pretén desvetllar l’interès dels alumnes pel funcionament de les gramàtiques de les sevesllengües a través de la mobilització d’un seguit d’estratègies que van més enllà del saber teòric o de l’ensenyament mecànic de la gramàtica i que es nodreixen de la realitat de l’aula entesa com a espai multilingüe. La iniciativa parteix de l’explotació de les intuïcions i del patrimoni lingüístic dels alumnes com a coneixedors de diverses llengües per tal de captar l’atenció sobre diferents aspectes de la gramàtica, a partir d’exercicis basats en un ventall d’estratègies que inclou els parells mínims, la construcció d’exemples o l’anàlisi de seqüències agramaticals.

description: By using state-of-the-art characterisation techniques including atom probe tomography and atomic resolved elemental mapping, we successfully probed the site occupation evolution associated with composition change in γ′, during 1100°C creep of a fourth generation Ru-bearing Ni-based superalloy. It is quantified that, W and Ru maintain unchanged site preference after creep rupture, while interestingly, the rest elements especially Co, Ta and Re show a weakened preference at both α- and β-sites in the γ′ lattice. This indicates the overall reduced γ′ ordering degree and thus the possible decrease in planar fault energies, which further facilitates dislocation shearing in γ′. Associated with the tremendous mass transfer during high-temperature creep, the site-occupation scenario in the γ′ lattice evolves as that, the preference at both α- and β-sites for Co, Ta and Re weakens while that of W and Ru remains nearly unchanged, indicating the overall decrease in ordering and thus the easier dislocation shearing in γ′.
Geological CO2 Storage Modelling Using Micro-Gravimetry

description: The invention of the portable iGrav superconducting gravimeter has provided unique precision and stability to monitor the subtle gravity field variations due to injection of CO2 into deep geological storages. According to the data collected over six months of continuous measurements by the iGrav001 at the University of Calgary, an accuracy of better than 1 µGal is achievable after corrections for environmental interferences, while the instrumental drift remains negligible. The combination of temporal observations of the iGrav along with observations of relative spring gravimeters, obtained in special network configurations, can lead to accuracies of 1-2 µGal for the gravity variations between two epochs before and after CO2 injection. In almost all previous CO2 storage modelling studies, the porosity change effect on the gravity signal has been assumed to be negligible. In this study, geological storages are divided into two major categories: unconfined and confined reservoirs. In the unconfined reservoirs, injected CO2 replaces the ambient fluid, causing a negative density anomaly in the reservoir and a negative gravity signal with negligible deformation at the ground surface. Confined reservoirs, on the other hand, experience a volumetric change and the injected CO2 fills the excessive porosity, causing a positive gravity signal representing the attraction of the injected CO2, and a positive ground surface deformation signal along with the associated free-air gravity effect. Dependency of gravity and ground deformation signals on variable properties, such as injected CO2 mass and density, along with reservoir depth and size, is examined by forward modelling for both confined and unconfined CO2 reservoirs. In addition, while inversion of the unconfined CO2 reservoirs obeys the conventional gravimetric modelling formulation, a novel inverse modelling formulation is established for confined reservoirs. A relationship is developed between the density changes and the fractional volumetric changes due to the CO2 injection in the confined reservoirs, and a linear inversion is implemented to estimate fractional volumetric changes using both ground deformation and gravity observations jointly. The developed inverse modelling methodology is evaluated using several synthetic case studies.
