Packed column supercritical fluid chromatography with total column effluent introduction to flame ionization detection
Creators: name: Gilbert, Shawn
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 95-98
description: This paper presents a novel Flame Ionization Detector (FID) capable of remaining lit at the high gaseous flow rates associated with Packed Column Supercritical Fluid Chromatography (pSFC) mobile phase decompression. Using a larger burner (3.9 mm i.d. by 80 mm long) and high hydrogen flow rates this FID has a capacity of about 3 L/min total flow. Design, optimization and characterization are discussed. Neat carbon dioxide (CO2) mobile phase limits pSFC to the separation of non­polar and moderately polar analytes. An organic modifier (most commonly methanol) is often used to extend the solvating power of the mobile phase towards chromatography of more polar analytes. Formic acid responds only minimally in the FID and to date has not been explored as the primary modifier in quantities exceeding 0.5% (v/v). The effect of formic acid modifier in relatively higher concentrations on chromatographic baseline, analyte retention, selectivity and peak shape will be discussed.

description: This paper studies parallelization schemes for stochastic Vector Quantization algorithms in order to obtain time speed-ups using distributed resources. We show that the most intuitive parallelization scheme does not lead to better performances than the sequential algorithm. Another distributed scheme is therefore introduced which obtains the expected speed-ups. Then, it is improved to fit implementation on distributed architectures where communications are slow and inter-machines synchronization too costly. The schemes are tested with simulated distributed architectures and, for the last one, with Microsoft Windows Azure platform obtaining speed-ups up to 32 Virtual Machines.
Exploiting bias in optimal finite-time copying protocols

description: We study a finite-time cyclic copy protocol that creates persisting correlations between a memory and a data bit. The average work to copy the two states of the data bit consists of the mutual information created between the memory and data bit after copying, a cost due to the difference between the initial and final states of the memory bit, and a finite-time cost. At low copy speeds, the optimal initial distribution of the memory bit matches the bias in the expected outcome, set by the bias in the data bit and the copying accuracies. However, if both states of the data are copied with the same accuracy, then in the high-speed regime copying the unlikely data bit state becomes prohibitively costly with a biased memory; the optimal initial distribution is then pushed towards 50:50. Copying with unequal accuracies, at fixed copy-generated mutual information, yields an opposite yet more effective strategy. Here, the initial memory distribution becomes increasingly biased as the copy speed increases, drastically lowering the work and raising the maximum speed. This strategy is so effective that it induces a symmetry breaking transition for an unbiased data bit.

description: X-shooter is the first 2nd generation instrument of the ESO Very Large Telescope(VLT). It is a very efficient, single-target, intermediate-resolution spectrograph that was installed at the Cassegrain focus of UT2 in 2009. The instrument covers, in a single exposure, the spectral range from 300 to 2500 nm. It is designed to maximize the sensitivity in this spectral range through dichroic splitting in three arms with optimized optics, coatings, dispersive elements and detectors. It operates at intermediate spectral resolution (R~4,000 - 17,000, depending on wavelength and slit width) with fixed echelle spectral format (prism cross-dispersers) in the three arms. It includes a 1.8"x4" Integral Field Unit as an alternative to the 11" long slits. A dedicated data reduction package delivers fully calibrated two-dimensional and extracted spectra over the full wavelength range. We describe the main characteristics of the instrument and present its performance as measured during commissioning, science verification and the first months of science operations.

description: This report summarizes a subset of the reef fish and benthic survey data collected by the Coral Reef Ecosystem Division for Pacific RAMP and for compatible PMNM, National Marine Fisheries Service (NMFS) and CRCP survey missions in 2014. Over that time period, surveys were conducted in the following regions: the Pacific Remote Island Areas, the Mariana Archipelago, and the Northwestern Hawaiian Islands. The status of reefs in each region is first described in the wider Pacific context (Section: U.S. Pacific reefs: the status of reef fish) and then at the island scale for each of the regions (Section: Island status and trends). Given the substantial changes in methods and design, this report specifically focuses on examining the observations collected since 2009, which only includes the subset of Pacific RAMP data that were collected using the SPC method under the depth-stratified random sampling design. In the final section, the publications that were produced in 2014 as a result of those surveys are listed; these publications either use the Pacific RAMP fish data or were coauthored by members of the CRED fish team and relevant to Pacific RAMP fish ecological monitoring work. All data used in this report along with other biological and climate-monitoring data collected by CRED for Pacific RAMP are available upon request.

They generalize to arbitrary dimension the concept of proportionally modular numerical semigroup of [7]. Several properties of these semigroups are proven. Affine convex body semigroups obtained from circles and polygons of R^2 are characterized. The algorithms for computing minimal system of generators of these semigroups are given. We provide the implementation of some of them.
Transport coefficients of ions in polyelectrolyte membrane channels

Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 68-69
description: The electrical properties of the nanopores play a crucial role in the transport of ions through polymeric materials employed in the construction of fuel cells. It is important to understand the potential field that originates from a fixed distribution of anionic charges, arranged on the pore wall, within these nanopores. A better understanding allows for a better qualitative and quantitative model of the molecular dynamics of ions that are transported through these pores. Once a good formulation of the potential field within the pore is obtained, it can be immediately applied to the calculation of the friction and diffusion coefficients, a most desirable result for the industrial constructors of fuel cells. This potential field was formulated for a basic pore model and used to obtain values for the friction coefficient, which were compared with experimental values to determine the validity of the pore model.

description: We study the dynamic behaviour of 1D spring-block models of friction when the external loading is applied from a side, and not on all blocks like in the classical Burridge-Knopoff-like models. Such a change in the loading yields specific difficulties, both from numerical and physical viewpoints. To address some of these difficulties and clarify the precise role of a series of model parameters, we start with the minimalistic model by Maegawa et al. (Tribol. Lett. 38, 313, 2010) which was proposed to reproduce their experiments about precursors to frictional sliding in the stick-slip regime. By successively adding (i) an internal viscosity, (ii) an interfacial stiffness and (iii) an initial tangential force distribution at the interface, we manage to (i) avoid the model's unphysical stress fluctuations, (ii) avoid its unphysical dependence on the spatial resolution and (iii) improve its agreement with the experimental results, respectively. Based on the behaviour of this improved 1D model, we develop an analytical prediction for the length of precursors as a function of the applied tangential load. We also discuss the relationship between the microscopic and macroscopic friction coefficients in the model.

description: Atmospheric NOx concentrations are declining steadily due to successful abatement strategies predominantly targeting combustion sources. On the European continent, total NOx emissions fell by 55% between 1990 and 2017, but only modest reductions were achieved from the agricultural sector; with 7.8% from 20 Eastern European countries and 19.1% from 22 Western European countries. Consequently, the share of agricultural NOx emissions for these 42 European countries have increased from 3.6% to 7.2%. These values are highly uncertain due to serious lack of studies from agricultural soils and manure management. The emission factor (EFNO 1.33%), currently used for calculating soil NOx emissions from European agricultural categories ‘N applied to soils’ and ‘manure management’ was evaluated here by including recently published data from temperate climate zones. The newly calculated EFNO (average 0.60%, 0.0625th%/0.5475th%, n = 65 studies) is not notably different from the current value, given the large uncertainties associated with the small pool of studies, and therefore continued use of EFNO (1.33%) is recommended until more data become available. An assessment of the contribution of agricultural and non-agricultural NOx sources found that of the 42 European countries, the 8 most populated countries achieved considerable reductions (1990–2017) from categories ‘non-agricultural sources’ (55%), ‘N applied to soils’ (43%) and ‘manure management’ (1.2%), compared to small reductions from the remaining 34 countries. Forests are also large sources of soil NOx. On average, emissions from Eastern European forests were 4 times larger than from ‘N applied agricultural soil’, whereas Western European NOx emissions from ‘N applied agricultural soil’ were two times larger than from forest soils. Given that non-agricultural sources of NOx continue to decline, soil related emissions from agriculture, forests and manure management become more important, and require rigorous investigation in order to improve atmospheric pollution forecasts.

Distribution and expression of protease genes in the Burkholderia cepacia complex
Creators: name: Gingues, Sonia
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 151-173
description: The distribution of the zinc metalloprotease gene, zmpA, and a sedolisin gene, scpB, was determined in the Burkholderia cepacia complex. Extracellular proteolytic activity correlated with the presence of zmpA with the exception of five strains that possess zmpA but are protease negative. To investigate the regulation of zmpA in these strains, zmpA::lacZ, zmpA::luxCDABE, cepl::luxCDABE and cepR::luxCDABE transcriptional fusions were constructed. zmpA, cepl and cepR genes are expressed in all the strains tested; however, different patterns of expression are observed. Protease activity of two of the five strains was restored by introduction of zmpA encoding an active protease. The amino acid sequence of the zinc metalloprotease from the two complemented strains was compared with that of an active protease. The two protease negative strains contain a serine to threonine substitution at position 489. ScpB mutants were constructed and scpB localized to the periplasm.

description: We present a differential measurement of the azimuthal anisotropy of charged hadron production in Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}$=2.76 TeV. This azimuthal anisotropy is expanded into a Fourier series in azimuthal angle, where the coefficient for each term, $v_n$, characterizes the magnitude of the anisotropy at a particular angular scale. We extract $v_2-v_6$ via a discrete Fourier analysis of the two-particle $Δϕ-Δη$ correlation with a large $Δη$ gap ($|Δη|>2$), and via an event plane method based on the Forward Calorimeter. Significant $v_2-v_6$ values are observed over a broad range in $\pT$, $η$ and centrality, and they are found to be consistent between the two methods in the transverse momentum region $\pT<3-4$ GeV. This suggests that the measured $v_2-v_6$ obtained from two-particle correlations at low $\pT$ with a large $Δη$ gap are consistent with the collective response of the system to the initial state geometry fluctuations, and is not the result of jet fragmentation or resonance decay.

description: We combine Differential Evolution, a new technique, with the traditional grid based method for optimization of solar neutrino oscillation parameters $Δm^2$ and $\tan^{2}θ$ for the case of two neutrinos. The Differential Evolution is a population based stochastic algorithm for optimization of real valued non-linear non-differentiable objective functions that has become very popular during the last decade. We calculate well known chi-square ($χ^2$) function for neutrino oscillations for a grid of the parameters using total event rates of chlorine (Homestake), Gallax+GNO, SAGE, Superkamiokande and SNO detectors and theoretically calculated event rates. We find minimum $χ^2$ values in different regions of the parameter space. We explore regions around these minima using Differential Evolution for the fine tuning of the parameters allowing even those values of the parameters which do not lie on any grid. We note as much as 4 times decrease in $χ^2$ value in the SMA region and even better goodness-of-fit as compared to our grid-based results. All this indicates a way out of the impasse faced due to CPU limitations of the larger grid method.

description: Amplified climate warming has led to permafrost degradation and a shortening of the winter season, both impacting cost-effective overland travel across the Arctic. Here we use, for the first time, four state-of-the-art Land Surface Models that explicitly consider ground freezing states, forced by a subset of bias-adjusted CMIP5 General Circulation Models to estimate the impact of different global warming scenarios (RCP2.6, 6.0, 8.5) on two modes of winter travel: overland travel days (OTDs) and ice road construction days (IRCDs). We show that OTDs decrease by on average −13% in the near future (2021–2050) and between −15% (RCP2.6) and −40% (RCP8.5) in the far future (2070–2099) compared to the reference period (1971–2000) when 173 d yr−1 are simulated across the Pan-Arctic. Regionally, we identified Eastern Siberia (Sakha (Yakutia), Khabarovsk Krai, Magadan Oblast) to be most resilient to climate change, while Alaska (USA), the Northwestern Russian regions (Yamalo, Arkhangelsk Oblast, Nenets, Komi, Khanty-Mansiy), Northern Europe and Chukotka are highly vulnerable. The change in OTDs is most pronounced during the shoulder season, particularly in autumn. The IRCDs reduce on average twice as much as the OTDs under all climate scenarios resulting in shorter operational duration. The results of the low-end global warming scenario (RCP2.6) emphasize that stringent climate mitigation policies have the potential to reduce the impact of climate change on winter mobility in the second half of the 21st century. Nevertheless, even under RCP2.6, our results suggest substantially reduced winter overland travel implying a severe threat to livelihoods of remote communities and increasing costs for resource exploration and transport across the Arctic.

description: We present a novel route to Bose-Einstein condensation devised for two-electron atoms, which do not admit practicable cooling techniques based upon narrow intercombination lines. A dipole trap for $^{40}$Ca atoms in the singlet ground state is loaded from a moderately cold source of metastable triplet atoms via spatially and energetically selective optical pumping permitting four orders of magnitude increase of the phase space density. Further cooling to quantum degeneracy is achieved by forced evaporation optimized to minimize three-body losses. In a combined loading and evaporation cycle of less than three seconds we are able to condense 3000 atoms.

description: The semi-arid Sahel is a global hotspot for poverty and malnutrition. Rainfed agriculture is the main source of food and income, making the well-being of rural population highly sensitive to rainfall variability. Studies have reported an upward trend in annual precipitation in the Sahel since the drought of the 1970s and early ‘80s, yet farmers have questioned improvements in conditions for agriculture, suggesting that intraseasonal dynamics play a crucial role. Using high-resolution daily precipitation data spanning 1981–2017 and focusing on agriculturally-relevant areas of the Sahel, we re-examined the extent of rainfall increase and investigated whether the increases have been accompanied by changes in two aspects of intraseasonal variability that have relevance for agriculture: rainy season duration and occurrence of prolonged dry spells during vulnerable crop growth stages. We found that annual rainfall increased across 56% of the region, but remained largely the same elsewhere. Rainy season duration increased almost exclusively in areas with upward trends in annual precipitation (23% of them). Association between annual rain and dry spell occurrence was less clear: increasing and decreasing frequencies of false starts (dry spells after first rains) and post-floral dry spells (towards the end of the season) were found to almost equal extent both in areas with positive and those with no significant trend in annual precipitation. Overall, improvements in at least two of the three intraseasonal variables (and no declines in any) were found in 10% of the region, while over a half of the area experienced declines in at least one intraseasonal variable, or no improvement in any. We conclude that rainfall conditions for agriculture have improved overall only in scattered areas across the Sahel since the 1980s, and increased annual rainfall is only weakly, if at all, associated with changes in the agriculturally-relevant intraseasonal rainfall characteristics.

description: The Canadian government is in the process of developing legislation and policies to reduce national levels of greenhouse gas emissions. The first wave of these initiatives is aimed at large industrial emitters. The goal of this project is to provide the latter with recommendations on how they can best account for their emissions to facilitate compliance with the emerging regulatory regime. The project begins by considering the technical constraints associated with accurately developing a greenhouse gas inventory. It then looks at constitutional issues that inform the types of laws and policies that may be developed at the federal and provincial level. It continues by detailing the emerging reporting framework and the trading markets. Best current industry accounting and reporting practices are then documented. The project concludes with a case study that evaluates the potential of an alternative accounting methodology - activity-based costing (ABC) - to provide higher quality data to decision makers in emitting firms. ABC was found to provide a number of advantages over current best practices. These include its ability to help identify internal emission reduction opportunities and their associated costs, improve the quality of internal reports to management and external reports to stakeholders, and provide valuable information for emissions management strategies. Together these advantages can assist firms in more effectively meeting the identified policies and legislation, reducing their exposure to emissions-related liabilities, and participating effectively in emissions trading markets.

description: We consider a model NISIN system with two junctions in series, where N is a normal metal, S is a superconductor and I is an insulator. We assume that the resistance of the first junction is high, while the resistance of the second one is low. In this case the first junction cools the left normal electrode, while the second junction partially removes excited quasiparticles from the superconductor. We consider cooling properties of this double junction structure. It is shown that the cooling power depends strongly on the ratio of the resistances of the two junctions. In conclusion, we derive a generalized expression for the cooling power of a NIS tunnel junction taking into account charge imbalance effects.

description: Introduction  Pregnancy is a risk factor for severe COVID-19 disease. Vaccine program has been offered as a priority to pregnant frontliners whose jobs considered high-risk exposure. We studied how the risk exposure of COVID-19 pregnant women affects maternal and neonatal outcomes. Method  We identified COVID-19 rt-PCR positive pregnant women who were admitted to Sibu Hospital from January to May 2021, who had been affected by surge of pandemic. We reviewed their case notes and collected sociodemographic information, maternal and neonatal outcomes. We compared the severity of disease and pregnancy outcomes between high and low exposure risk groups. Result  We identified 119 COVID-19 pregnant women; 44 (37.0%) subjects were considered high-risk exposure. None were vaccinated for COVID-19. There were no significant differences between the low- and high-risk groups for medical and sociographic factors. There was also no significant difference between the risk exposures for COVID-19 severity, intensive care admission, need for ventilation and premature delivery. For those who delivered, 45.5% (n=5) of the high-risk group delivered prematurely with an odds ratio of 15.0 (95% CI: 1.46, 155.3, p = 0.023). Otherwise, there was no significant difference in other neonatal outcomes. No neonate was tested positive for COVID-19. Discussion/Conclusion  A significant number of low-risk COVID-19 exposure subjects in our cohort developed severe COVID-19 and equally likely to have unwanted maternal and neonatal outcomes. Thus, pregnant women are all vulnerable to develop severe COVID-19 regardless of their risks' exposure. Our study finding highlights the importance of COVID-19 vaccination for all pregnant women.

A data mining framework for efficient discovery of classification rules
Creators: name: Gopalan, Janaki
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 103-110
description: Associative classification is an important research topic in data mining (DM). The thesis proposes a framework to derive accurate and interesting classification rules using the association rule mining (ARM) technique. To effectively address the rule discovery task, in the framework, two fundamental problems in the pre-processing and the post-processing components of the DM process are identified. In the pre­processing component, it is identified that the choice of the training set is an impor­tant factor in deriving good classification rules. The thesis proposes a novel technique using a genetic algorithm (GA) to find an appropriate split of a dataset into training and test sets. Using the obtained training set as the input to the ARM technique generates high accuracy classification rules. It is also identified that an algorithm (or heuristic) is required to find the best set of interesting and accurate rules from the discovered ones. In the post-processing component, the thesis proposes a pruning strategy using a GA to find the accurate interesting rules.

Planets Across Space and Time (PAST) IV: The Occurrence and Architecture of Kepler Planetary Systems as a Function of Kinematic Age Revealed by the LAMOST-Gaia-Kepler Sample

description: One of the fundamental questions in astronomy is how planetary systems form and evolve. Measuring the planetary occurrence and architecture as a function of time directly addresses this question. In the fourth paper of the Planets Across Space and Time (PAST) series, we investigate the occurrence and architecture of Kepler planetary systems as a function of kinematic age by using the LAMOST-Gaia-Kepler sample. To isolate the age effect, other stellar properties (e.g., metallicity) have been controlled. We found the following results. (1) The fraction of stars with Kepler-like planets (FKep) is about 50% for all stars; no significant trend is found between FKep and age. (2) The average planet multiplicity (Np) exhibits a decreasing trend ( ∼2σ significance) with age, which decreases from Np ~ 2.6–2.7 for stars younger than 1 Gyr to Np ∼ 1.8–2.0 for stars older than 8 Gyrs. (3) The number of planets per star (η=FKep ×Np) shows a more pronounced decreasing trend (∼3σ significance), which decreases from η ∼ 1.4–1.5 for young stars to η ∼ 0.9–1.0 for old stars. (4) The median mutual orbital inclination of the planets (σi,k) increases from 2.2 to 3.9 as stars aging, and both the Solar System and the Kepler planetary systems fit such a trend. The nearly independence of FKep ∼ 50% on age implies that planet formation is robust and stable across the Galaxy history. The age dependence of Np and σi,k demonstrates that planetary architecture is evolving, and planetary systems generally become dynamically hotter with fewer planets as they age.
Deep decarbonisation of buildings energy services through demand and supply transformations in a 1.5°C scenario

description: Buildings energy consumption is one of the most important contributors to greenhouse gas (GHG) emissions worldwide, responsible for 23% of energy-related CO2 emissions. Decarbonising the energy demand of buildings will require two types of strategies: first, an overall reduction in energy demand, which could, to some extent, be achieved at negative costs; and second through a reduction of the carbon content of energy via fuel switching and supply-side decarbonisation. This study assesses the contributions of each of these strategies for the decarbonisation of the buildings sector in line with a 1.5°C global warming. We show that in a 1.5°C scenario combining mitigation policies and a reduction of market failures in efficiency markets, 81% of the reductions in buildings emissions are achieved through the reduction of the carbon content of energy, while the remaining 19% are due to efficiency improvements which reduce energy demand by 31%. Without supply-side decarbonisation, efficiency improvements almost entirely suppress the doubling of emissions that would otherwise be expected, but fail to induce an absolute decline in emissions. Our modelling and scenarios show the impact of both climate change mitigation policies and of the alleviation of market failures pervading through energy efficiency markets. The results show that the reduction of the carbon content of energy through fuel switching and supply-side decarbonisation is of paramount importance for the decarbonisation of buildings.
Forging the gypsy identity in Victorian England
Creators: name: Gordon, Mary 'Patricia'
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 128-139
description: This thesis examines the interplay among religious, political, scientific, and cultural constructions of gypsies in Victorian England. In the nineteenth century, evangelicals expanded their conversion efforts to include gypsies. While some evangelicals portrayed the gypsies as noble savages, other Christian reformers presented the gypsy as a model of wantonness. At this time, the social sciences and gypsiology emerged as distinct fields of inquiry. Gypsiologists divided gypsies into authentic and mongrel breeds, thus creating a contrasting image of the gypsy. The scientific invention of a criminal type, such as the gypsy, stimulated the bourgeois creation of a criminal class, which was validated through legislation. Victorian authors similarly sought to present their knowledge of the gypsy. The forging of the gypsy, however, reflected the bourgeoisie's preoccupation with the past, ranking humans, fears of decadence, and their need to confirm their superiority, which was rooted in notions of respectability and Englishness.
