Publisher: name: FID GEO
Year: 2020

description: The biogeochemical functioning of soils (e.g., soil carbon stabilization and nutrient cycling) is determined at the interfaces of specific soil structures (e.g., aggregates, particulate organic matter (POM) and organo-mineral associations). With the growing accessibility of spectromicroscopic techniques, there is an increase in nano- to microscale analyses of biogeochemical interfaces at the process scale, reaching from the distribution of elements and isotopes to the localization of microorganisms. A widely used approach to study intact soil structures is the fixation and embedding of intact soil samples in resin and the subsequent analyses of soil cross-sections using spectromicroscopic techniques. However, it is still challenging to link such microscale approaches to larger scales at which normally bulk soil analyses are conducted. Here we report on the use of laboratory imaging Vis–NIR spectroscopy on resin embedded soil sections and a procedure for supervised image classification to determine the microscale soil structure arrangement, including the quantification of soil organic matter fractions. This approach will help to upscale from microscale spectromicroscopic techniques to the centimetre and possibly pedon scale. Thus, we demonstrate a new approach to integrate microscale soil analyses into pedon-scale conceptual and experimental approaches. Highlights: Quantification of soil constituents using Vis-NIR spectroscopy. New approach to use resin embedded soil core sections with intact structure. Reproducible quantification of soil constituents important for soil carbon storage. Vis-NIR as promising tool for upscaling from microscale to pdeon scale.

Regionalized life cycle assessment of renewable energy and waste valorization technologies for the Canadian egg industry
Creators: name: Kanani, Farah
Publisher: name: University of British Columbia
Year: 2021

description: Egg production in Canada has increased substantially in the past decades. Over 789 million dozen eggs were produced by the industry in 2020. Due to being the fastest growing market among livestock products along with increasing scrutiny regarding the sustainability impacts of livestock production, the industry is striving towards reducing its net emissions and overall environmental footprint. Green technologies offer opportunities for mitigating resource use and emissions in the egg industry. However, to date, there has been no systematic accounting of the distribution, scale, feasibility, mitigation potential and scalability of these technologies specifically for the Canadian egg industry. The purpose of the research reported was to identify a subset of renewable energy and waste valorization technology options and deployment scenarios that are potentially most suitable for Canadian egg farms and to thereafter perform regionalized life cycle assessments to understand and compare the relative efficacy and feasibility of these technologies for application in the Canadian egg industry. The results of these analyses demonstrate the potential to substantially reduce resource use and emissions per tonne of eggs produced in four key provinces (Alberta, Saskatchewan, Nova Scotia, New Brunswick) that operate predominantly on a fossil-fuel based electricity grid. Both solar and wind energy (wind speeds > 4 m/s) technologies are suitable in these provinces, with reasonable environmental impact payback times (eIPBTs). In provinces with greener electricity grid mixes (British Columbia, Ontario, Newfoundland and Labrador), long eIPBTs preclude consideration of on-farm solar PV systems and a minimal emissions reductions potential associated with on-farm wind turbine installations. Results for Prince Edward Island were mixed. This was the same case for two principal waste valorization technologies identified as potential options for the egg industry (anaerobic co-digestion and gasification). Based on an LCA study, both technologies were found to be more beneficial than direct land application of manure, with the exception of land occupation impacts. Anaerobic co-digestion has the greatest resource use/emissions reduction potential. This study emphasizes the importance of regionalization in LCA in order to accurately characterize potential life cycle impacts in agricultural systems and candidate mitigation technologies, which are highly variable in time and space.

description: We aimed to explore (i) what adults with hearing difficulties want and need from hearables, which we defined as any non-medical personal sound amplification product, and (ii) what hearing care professionals think about hearables. This was an exploratory, qualitative study conducted using separate focus groups with adults with hearing difficulties and audiologists. Data were analysed inductively using reflexive thematic analysis. Participants were 12 adults with hearing difficulties and 6 audiologists. Adults with hearing difficulties expressed desire for trustworthy information and support, described evaluating hearables and other devices according to diverse personal criteria, and expressed willingness to vary their budget according to product quality. Audiologists expressed views that hearables are an inferior product but useful tool, that it is not necessarily their role to assist with hearables, that hearables are a source of uncertainty, and that the provision of hearables by audiologists is not currently practical. Adults with hearing difficulties may have complex reasons for considering hearables and may desire a high level of clinical support in this area. Ongoing research into the efficacy and effectiveness of hearables is needed together with research into effective strategies to incorporate hearables into clinical practice.

description: Winter chill is expected to decrease in many of the suitable growing regions for deciduous trees. Argentinean North Patagonia hosts extensive fruit tree cultivation, which provides an important contribution to both local and global food security. Using historic records from 11 weather stations from North Patagonia, we evaluate the possible impacts of climate change on fruit tree cultivation. We assess winter chill and seasonal heat availability, and the risk of spring frost events based on outputs from 15 Global Climate Models (GCMs) for two Representative Concentration Pathway (RCP) scenarios and two future time periods (represented by central years 2050 and 2085). Metrics were estimated for 47 years of records from the weather stations, as well as typical conditions for 10 past scenarios and 60 future GCM and RCP projections. Scenarios consisted of 100 plausible annual temperature records produced by a weather generator. Results suggest that fruit tree dormancy in Argentinean North Patagonia will not be strongly affected by climate change. Compared to the past, winter chill may only decrease by 9% in the RCP4.5 scenario by 2050 in the northeastern and eastern subregion, while in the central-south and west the reduction seems unlikely to exceed 6% by the same RCP scenario and year. Our models project stable high growing season heat in the northeastern and eastern regions, and major increases in the south by 2085 in both RCP scenarios. Projections of spring frost events varied between 0 and about 25 hours below 0°C depending on the site. Increasing heat availability may create opportunities for fruit and nut growers to introduce new species and cultivars to the region. Our results provide a basis for planning such introductions and for enabling growers to exploit new opportunities for producing temperate orchard crops beyond their traditional ranges.

description: The concept of ecosystem services (ES) creates understanding of the value of ecosystems for human well-being. With regard to soils, it provides a framework for assessments of soil contributions and soil management impacts. However, a lack of standardization impedes comparisons between assessment studies and the building of synthesis information. The Common International Classification of Ecosystem Services (CICES) is an important step forward, although its application to soils is not without difficulty. CICES version 5.1 defines 83 ES classes, of which only some are relevant for soils. We compiled two subsets of CICES classes: one set of soil-related ES comprising 29 services defined as directly and quantifiably controlled by soils and their properties, processes and functions, and another set of 40 ES defined as being affected by agricultural soil management. Additionally, we conducted a systematic literature review, searching for published lists of soil-related ES that claim completeness. We identified 11 relevant lists. Of all CICES classes, 12 were included in more than 75% of the lists, whereas another 36 classes were included in 25–75% of them. Regarding the suitability of the CICES classification for addressing ES in the context of soils and their agricultural management, we identified constraints, such as overlaps, gaps, and highly specific or very broad class definitions. Close cooperation between the soil research and ES communities could ensure better consideration of soils in future CICES updates. A shortlist of 25 service classes affected by agricultural soil management facilitates a standardized approach and may function as checklists in impact assessments. Highlights: Standardized definitions are needed to allow meta-analysis of ecosystem service studies and improve assessments. CICES defines 83 detailed classes of ecosystem services, suggested as a “default list”. We identified 29 classes as soil related and 40 classes as affected by agricultural soil management. Both subsets facilitate ecosystem service assessments in soil research and comparability of results.

description: We quantify the prospects for using emission lines from rotational transitions of the CO molecule to perform an `intensity mapping' observation at high redshift during the Epoch of Reionization (EoR). The aim of CO intensity mapping is to observe the combined CO emission from many unresolved galaxies, to measure the spatial fluctuations in this emission, and use this as a tracer of large scale structure at very early times in the history of our Universe. This measurement would help determine the properties of molecular clouds -- the sites of star formation -- in the very galaxies that reionize the Universe. We further consider the possibility of cross-correlating CO intensity maps with future observations of the redshifted 21 cm line. The cross spectrum is less sensitive to foreground contamination than the auto power spectra, and can therefore help confirm the high redshift origin of each signal. Furthermore, the cross spectrum measurement would help extract key information about the EoR, especially regarding the size distribution of ionized regions. We discuss uncertainties in predicting the CO signal at high redshift, and discuss strategies for improving these predictions. Under favorable assumptions, and feasible specifications for a CO survey mapping the CO(2-1) and CO(1-0) lines, the power spectrum of CO emission fluctuations and its cross spectrum with future 21 cm measurements from the MWA are detectable at high significance.

description: Cluster dynamical mean field calculations based on 2, 4, 8 and 16 site clusters are used to analyze the doping-driven metal-insulator transition in the two dimensional Hubbard model. Comparison of results obtained on different clusters enables a determination of those aspects of the physics that are common to all clusters and permits identification of artifacts associated with particular cluster geometries. A modest particle-hole asymmetry in the underlying band structure is shown to lead to qualitatively different behavior on the hole doped side than on the electron doped side. For particle-hole asymmetry of the sign and magnitude appropriate to high-$T_c$ cuprates, the approach to the insulator from the hole-doping side is found to proceed in two stages from a high-doping region where the properties are those of a Fermi liquid with moderately renormalized parameters and very weak momentum dependence. As doping is reduced the system first enters an intermediate doping regime where the Fermi liquid renormalizations are larger and the electron self energy varies significantly around the Fermi surface and then passes to a small doping regime characterized by a gap in some regions of the Fermi surface but gapless behavior in other regions. On the electron doped side the partially gapped regime does not occur, and the momentum dependence of the electron self energy is less pronounced. Implications for the high-$T_c$ cuprates and for the use of cluster dynamical mean field methods in wider classes of problems are discussed.

description: Upwelling ocean currents associated with oxygen minimum zones (OMZs) supply nutrients fuelling intense marine productivity. Perturbations in the extent and intensity of OMZs are projected in the future, but it is currently uncertain how this will impact fluxes of redox-sensitive trace metal micronutrients to the surface ocean. Here we report seawater concentrations of Fe, Mn, Co, Cd, and Ni alongside the redox indicator iodide/iodate in the Peruvian OMZ during the 2015 El Niño event. The El Niño drove atypical upwelling of oxygen-enriched water over the Peruvian Shelf, resulting in oxidized iodine and strongly depleted Fe (II), total dissolved Fe, and reactive particulate Fe concentrations relative to non-El Niño conditions. Observations of Fe were matched by the redox-sensitive micronutrients Co and Mn, but not by non-redox-sensitive Cd and Ni. These observations demonstrate that oxygenation of OMZs significantly reduces water column inventories of redox-sensitive micronutrients, with potential impacts on ocean productivity.

description: Heat transport in natural porous media, such as aquifers or streambeds, is generally modeled assuming local thermal equilibrium (LTE) between the fluid and solid phases. Yet, the mathematical and hydrogeological conditions and implications of this simplification have not been fully established for natural porous media. To quantify the occurrence and effects of local thermal disequilibrium during heat transport, we systematically compared thermal breakthrough curves from a LTE with those calculated using a local thermal nonequilibrium (LTNE) model, explicitly allowing for different temperatures in the fluid and solid phases. For the LTNE model, we developed a new correlation for the heat transfer coefficient representative of the conditions in natural porous aquifers using six published experimental results. By conducting an extensive parameter study (>50,000 simulations), we show that LTNE effects do not occur for grain sizes smaller than 7 mm or for groundwater flow velocities that are slower than 1.6 m day−1. The limits of LTE are likely exceeded in gravel aquifers or in the vicinity of pumped bores. For such aquifers, the use of a LTE model can lead to an underestimation of the effective thermal dispersion by a factor of up to 30 or higher, while the advective thermal velocity remains unaffected for most conditions. Based on a regression analysis of the simulation results, we provide a criterion which can be used to determine if LTNE effects are expected for particular conditions.

description: Aims: The aim of this research was to identify the effectiveness and experience of exercise in adults with systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). Methods: Study 1 is a systematic review on the effectiveness of exercise as adjunct therapy in SLE. Study 2 is a systematic review protocol on exercise and physical therapy in SSc and is ongoing. Study 3 is a qualitative interview study exploring rheumatology practitioners’ perspectives of exercise in SLE and SSc. Study 4 is a qualitative focus group study exploring the perspectives of exercise in SSc. Study 5 is a mixed method non-randomised controlled pilot trial exploring the effectiveness of telehealth-supervised exercise in SLE. Results. Exercise is undoubtedly a highly valued intervention by rheumatologists, rheumatology nurses, and people living with SLE and SSc, with several measured and perceived benefits and barriers to exercise. Overall, exercise is ‘safe’, with no reported adverse effects, and is effective in reducing levels of fatigue and depression and improving physical fitness and physical functioning in people with SLE, and has the potential to improve aerobic capacity, exercise tolerance, muscular endurance, fatigue, pain, and life satisfaction in people with SSc. Rheumatology practitioners describe exercise to be beneficial for people with SLE and SSc with few concerns about its safety, admittedly lack time and confidence to prescribe specific exercise for their patients, and importantly, recommend long-term and supervised exercise for this population. People with SSc also describe several benefits to exercise, address disease-related barriers to engaging in exercise, and raise the importance of modified supervised exercise. Key findings from our mixed-method investigation suggest that telehealth-supervised exercise was feasible for, and well-accepted by, adults with SLE, and resulted in some modest health improvements. Importantly, participants described telehealth-supervised exercise as efficient, despite some challenges of exercising from home (such as limited equipment and space), were satisfied by the experience, and would engage in telehealth-supervised again. Conclusion: This thesis provides researchers, exercise professionals, rheumatology practitioners, and people with SLE and SSc, with a more comprehensive understanding about the beneficial effects of exercise and highlights some opportunities for further research.

description: We have derived disk scale lengths for 30374 non-interacting disk galaxies in all five SDSS bands. Virtual Observatory methods and tools were used to define, retrieve, and analyse the images for this unprecedentedly large sample classified as disk/spiral galaxies in the LEDA catalogue. Cross correlation of the SDSS sample with the LEDA catalogue allowed us to investigate the variation of the scale lengths for different types of disk/spiral galaxies. We further investigat asymmetry, concentration, and central velocity dispersion as indicators of morphological type, and are able to assess how the scale length varies with respect to galaxy type. We note however, that the concentration and asymmetry parameters have to be used with caution when investigating type dependence of structural parameters in galaxies. Here, we present the scale length derivation method and numerous tests that we have carried out to investigate the reliability of our results. The average r-band disk scale length is 3.79 kpc, with an RMS dispersion of 2.05 kpc, and this is a typical value irrespective of passband and galaxy morphology, concentration, and asymmetry. The derived scale lengths presented here are representative for a typical galaxy mass of $10^{10.8\pm 0.54} \rm{M}_\odot$, and the RMS dispersion is larger for more massive galaxies. Distributions and typical trends of scale lengths have also been derived in all the other SDSS bands with linear relations that indicate the relation that connect scale lengths in one passband to another. Such transformations could be used to test the results of forthcoming cosmological simulations of galaxy formation and evolution of the Hubble sequence.

Process-Based Simulation of Aerosol-Cloud Interactions in a One-Dimensional Cirrus Model
Creators: name: Kärcher, B.
Publisher: name: FID GEO
Year: 2020

description: A new microphysical cirrus model to simulate ice crystal nucleation, depositional growth, and gravitational settling is described. The model tracks individual simulation ice particles in a vertical column of air and allows moisture and heat profiles to be affected by turbulent diffusion. Ice crystal size- and supersaturation-dependent deposition coefficients are employed in a one-dimensional model framework. This enables the detailed simulation of microphysical feedbacks influencing the outcome of ice nucleation processes in cirrus. The use of spheroidal water vapor fluxes enables the prediction of primary ice crystal shapes once microscopic models describing the vapor uptake on the surfaces of cirrus ice crystals are better constrained. Two applications addressing contrail evolution and cirrus formation demonstrate the potential of the model for advanced studies of aerosol-cirrus interactions. It is shown that supersaturation in, and microphysical and optical properties of, cirrus are affected by variable deposition coefficients. Vertical variability in ice supersaturation, ice crystal sedimentation, and high turbulent diffusivity all tend to decrease homogeneously nucleated ice number mixing ratios over time, but low ice growth efficiencies counteract this tendency. Vertical mixing induces a tendency to delay the onset of homogeneous freezing. In situations of sustained large-scale cooling, natural cirrus clouds may often form in air surrounding persistent contrails.

description: Some adults experience challenges in successfully communicating their listening difficulties to their audiologist, and report feeling that they are not always listened to or understood. This project examined adults’ recollections of discussions with their audiologist to explore (1) how adults report describing their listening difficulties and (2) information that adults report they do not communicate, or do not communicate successfully, to their audiologist. Individual semi-structured interviews were conducted. Interview transcripts were analysed using a template analysis approach. Fifteen adults who self-report listening difficulties, and who had previously consulted an audiologist. Four themes were identified from adults’ recollections of how they describe their listening difficulties: (1) situation or context of listening difficulties, (2) behavioural responses, (3) impacts of listening difficulties and (4) contributing factors. Adults report not always successfully communicating (1) emotional concerns and impacts, (2) descriptions of sound quality and (3) descriptions of changed listening experiences. Results provide insights about the times when adults feel that communication with their audiologist is successful, or unsuccessful. The results are useful for informing interventions to help adults and audiologists communicate more effectively together. To further inform interventions, factors affecting adults’ communication should be explored.

description: This study aimed to provide a conceptual model to understand what typifies the lived experience of hearing loss. A grounded theory informed study of adults with hearing loss (n = 46) who participated in individual interviews. The data were analysed in line with the constant comparative approach of grounded theory. A substantial patient and public engagement (PPIE) strategy underpinned decisions and processes throughout. Adults were recruited from age bands (16–29; 30–49;50–79 and 80 upwards) to provide different lived experience. We recruited individuals from across the UK including urban, sub-urban and rural communities and included a typical constituency of each location including black and minority ethnic participants. Our PPIE groups included adults often marginalised in research including South Asian community groups, adults in residential care and those with additional disabilities. We identified the consistent features of the lived experience with hearing loss, as the individualised responsibility that hearing loss confers. These are an individual auditory lifeworld; social comparison and social support; individual and patient-centred care and individual agency and capability. This work provides new insights for those practising audiology and highlights the importance of building social support systems through implementation of family and peer support approaches.

description: U.S. soybean and soybean meal exports have experienced considerable competitive pressure from South American exports in the last decade. The recent decline in the U.S. share has renewed interest in determining whether cleaner soybeans would help the competitiveness of the U.S. soybean sector. Mandating cleaner soybeans under current production and marketing practices would have a minor effect on the market share or value of U.S. soybean exports. Soybean crushers, who dominate imports of soybeans, are largely concerned about relative prices between oilseeds and meals and their oil and protein content, though cleanliness does play a secondary role in the decisionmaking process.

"We don't need your constitution" : patriation and Indigenous self-determination in British Columbia
Creators: name: Feltes, Emma
Publisher: name: University of British Columbia
Year: 2021

description: In November 1980, the Union of BC Indian Chiefs (UBCIC) chartered two trains from Vancouver to Ottawa, launching a movement dubbed the “Constitution Express.” At the time, Prime Minister Pierre Trudeau promised to “patriate” the Constitution from the UK. It was a move touted as decolonial, yet it excluded any mention of Indigenous Peoples, their rights, or self-determination. So, they set out to thwart him. Over two years, the movement made many more journeys: to the United Nations; through Europe; and ultimately, to London. Each carried the same message: no patriation. At least not without the consent of the Indigenous nations on top of whose territories and terms the Canadian state tenuously sits. By the time of the Constitution Act, 1982, what they got was section 35, which “recognized and affirmed” existing Aboriginal and treaty rights, yet to be defined. For a movement so significant in breath, scale, and consequence, it has received stunningly little academic attention. This dissertation follows the movement’s journey. Each chapter is set in a new location where the movement made its case. It asks: In what ways did the movement confront Canada’s claims of exclusive jurisdiction in the patriation period? And what did it propose instead? To answer these questions, I undertook more than 18 months of research in partnership with the movement’s leaders, participants, and theoreticians. Their recollections and analyses drive the narrative, bolstered by archival material. As a settler anthropologist, they also taught me how bring my methods in line with the very topic at hand: Indigenous self-determination. I learned from those involved that this was not just a movement for Constitutional rights recognition. This dissertation focuses on a different imperative at the heart of the movement: jurisdiction. The Constitution Express reasserted Indigenous Peoples’ nationhood, territorial authority, and self-determination. It also reconstituted the Canadian state, drawing on resurgent Indigenous legal traditions to imagine a federalism stripped of Imperial domination, based on consent. Taking inspiration from Third World anti-colonialism, it revamped international law to seek decolonization, not patriation. Ultimately, I conclude it was a simultaneously local and transnational movement with deep resonance today.

description: We compute exact thermodynamic geometric properties of the non-abelian quarkonium bound states from the consideration of one-loop strong coupling. From the general statistical principle, the intrinsic geometric nature of strongly coupled QCD is analyzed for the Columbic, rising and Regge rotating regimes. Without any approximation, we have obtained the non-linear mass effect for the Bloch-Nordsieck rotating strongly coupled quarkonia. For a range of physical parameters, we show in each cases that there exists a well-defined, non-degenerate, curved, intrinsic Riemannian manifold. As the gluons become softer and softer, we find in the limit of the Bloch-Nordsieck resummation that the strong coupling obtained from the Sudhakov form factor possesses exact local and global thermodynamic properties of the underlying mesons, kaons and $D_s$ particles.

description: The article is devoted to solving the problem of the reliability of industrial building structures: crane and roof beams, columns, redundant building systems. For this aim, the probabilistic method of structural reliability estimation is developed after the criterion of bearing strength, in which the main component of structure reliability is faultlessness. The method takes account of the random loads and material strength, loads joint action, the specific character of work and failure elements, nodes and the whole structure as well. For the ground of method, the large amount of statistic results on crane load is examined for the bridge cranes of the different types. A large amount of wind and snow meteorological data is collected for the territory of Ukraine. Stationary probabilistic model of crane load and quasi-stationary model of the snow and mean wind load are substantiated. The most widely spread probabilistic presentations of random loads are observed. They are as follows: stationary random process and its absolute maxima, random sequence of independent and correlated loads, discrete presentation and extreme model. It was deduced that the redundant structure reliability estimation is a very complicated problem as depends upon the system complexity. The method of states, a probabilistic method of ultimate equilibrium and logic and probabilistic method are developed for solving this problem. On the base of the determined method, the numerical reliability computations of a wide range of industrial building structures are realized. It is shown that the structures have quite different levels of reliability. In particular, the light roof structures are not reliable enough being under the great influence of snow load. At the same time, the Design Code allows over-estimation of reliability for industrial columns. The estimation of industrial redundant structures with a different degree of redundancy is obtained on the base of developed approach. It gave the possibility to evaluate the high safety level of redundant structures in comparison with separate members and statically determined structures. With regard to mentioned results, it is recommended to correct some load factors, a combination factor and a factor for model uncertainties of the Design Codes of structures and loads.

description: The U.S. hog production industry has experienced significant structural change during the past decade. Fewer and larger operations have more and more come to characterize the industry. Data from the Farm Costs and Returns Survey are used to describe the hog production industry in 1992 and to examine some of the issues resulting from structural change. Characteristics and production costs are presented for various types of hog operations. Also, the distribution of hog production costs, size relationships in hog production, regional changes in hog production, and production contract activity in the hog industry are examined.
