Year: 2008
Subjects: subject: Engineering, Electronics and Electrical.

description: The use of CO2 at sub-critical states and formation of porous structures with porosity gradients and interconnectivities from biodegradable polymers and their blends were investigated. Porous structures with well-defined pore sizes ranging from very large (i.e. d>100mum) to very small pores (i.e. d<10mum) were prepared by foaming multilayered films of poly (dl-lactic-co-glycolic acid) (PLGA 50/50), poly &egr;-caprolactone (PCL), poly (dl-lactic-co-caprolactone) (PLCL) and their blends. In order to improve the interconnectivity, a ternary system comprised of poly (lactic-co-glycolic acid) (PLGA 50/50)/poly (ethylene glycol) (PEG)/ethanol (C2H5OH)/CO2 was foamed by CO2 under sub-critical conditions. By varying the PEG concentration in the mixture, and subsequently foaming the samples by either pressure quench or temperature quench, an interconnected porous structure was generated. Investigations demonstrated that the (PLGA 50/50)/PEG blend in ratios of 95/5, 90/10, 75/25, 50/50 and 33/67 wt% can be foamed into a wide range of pore sizes from 10 to 500 mum and opening sizes from 5 to 250 mum. The generated scaffolds geometry in the investigated systems ranged from partially open to completely open, well interconnected, homogeneous or heterogeneous big pore structures. The scaffolds could find potential applications in tissue engineering.

description: Background: Street-involved youth are more likely to experience trauma and adverse events in childhood; however, little is known about exposure to the child welfare system among this vulnerable population. This study sought to examine the prevalence and correlates of being in government care among street-involved youth in Vancouver, Canada. Methods: From September 2005 to November 2012, data were collected from the At-Risk Youth Study, a prospective cohort of street-involved youth aged 14–26 who use illicit drugs. Logistic regression analysis was employed to identify factors associated with a history of being in government care. Results: Among our sample of 937 street-involved youth, 455 (49%) reported being in government care at some point in their childhood. In a multivariate analysis, Aboriginal ancestry (adjusted odds ratio [AOR] = 2.07; 95% confidence interval [CI]: 1.50 – 2.85), younger age at first “hard” substance use (AOR = 1.10; 95% CI: 1.05 – 1.16), high school incompletion (AOR = 1.40; 95% CI: 1.00 – 1.95), having a parent that drank heavily or used illicit drugs (AOR = 1.48; 95% CI: 1.09 – 2.01), and experiencing physical abuse (AOR = 1.90; 95% CI: 1.22 – 2.96) were independently associated with exposure to the child welfare system. Conclusions: Youth with a history of being in government care appear to be at high-risk of adverse illicit substance-related behaviours. Evidence-based interventions are required to better support vulnerable children and youth with histories of being in the child welfare system, and prevent problematic substance use and street-involvement among this population.

description: Fracton phases of matter are gapped phases of matter that, by dint of their sensitivity to UV data, demand non-standard quantum field theories to describe them in the IR. Two such approaches are foliated quantum theory and exotic field theory. In this paper, we explicitly construct a map from one to the other and work out several examples. In particular, we recover the equivalence between the foliated and exotic fractonic BF theories recently demonstrated at the level of operator correspondence. We also demonstrate the equivalence of toric code layers and the anisotropic model with lineons and planons to the foliated BF theory with one and two foliations, respectively. Finally, we derive new exotic field theories that provide simple descriptions of hybrid fracton phases from foliated field theries known to do so. Our results both provide new examples of exotic field theories and pave the way toward their systematic construction from foliated field theories.

description: This registration consists of a list of research questions and predictions for the collaborative project, “The Evolutionary Dynamics of Religion, Family Size, and Child Success,” funded by the Templeton Foundation (https://www.evolutionarydemographyofreligion.org). More information about the project is available on its OSF page: https://osf.io/b865v/. The primary objective of this project is to provide novel cross-cultural data to study the relationship between religion, family size, cooperation, and women and children’s wellbeing. Using newly collected demographic, ethnographic and physiological data from five countries - Bangladesh, the Gambia, India, Malawi, and the United States - we aim to answer ten research questions (RQs) and make a number of specific predictions for each. We also include a list of key indicators, a brief outline of the study design, and a data analysis plan. As this project involves a complex multi-site qualitative and quantitative data collection process, we anticipate that these documents may be updated after data collection is complete due to potential constraints during data collection.
The effects of exercise on cognition in Parkinson’s disease: a systematic review

description: Cognitive impairments are highly prevalent in Parkinson’s disease (PD) and can substantially affect a patient’s quality of life. These impairments remain difficult to manage with current clinical therapies, but exercise has been identified as a possible treatment. The objective of this systematic review was to accumulate and analyze evidence for the effects of exercise on cognition in both animal models of PD and human disease. This systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Fourteen original reports were identified, including six pre-clinical animal studies and eight human clinical studies. These studies used various exercise interventions and evaluated many different outcome measures; therefore, only a qualitative synthesis was performed. The evidence from animal studies supports the role of exercise to improve cognition in humans through the promotion of neuronal proliferation, neuroprotection and neurogenesis. These findings warrant more research to determine what roles these neural mechanisms play in clinical populations. The reports on cognitive changes in clinical studies demonstrate that a range of exercise programs can improve cognition in humans. While each clinical study demonstrated improvements in a marker of cognition, there were limitations in each study, including non-randomized designs and risk of bias. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used and the quality of the evidence for human studies were rated from “low” to “moderate” and the strength of the recommendations were rated from “weak” to “strong”. Studies that assessed executive function, compared to general cognitive abilities, received a higher GRADE rating. Overall, this systematic review found that in animal models exercise results in behavioral and corresponding neurobiological changes in the basal ganglia related to cognition. The clinical studies showed that various types of exercise, including aerobic, resistance and dance can improve cognitive function, although the optimal type, amount, mechanisms, and duration of exercise are unclear. With growing support for exercise to improve not only motor symptoms, but also cognitive impairments in PD, health care providers and policy makers should recommend exercise as part of routine management and neurorehabilitation for this disorder.
Realistic models of star cluster evolution: bridging the gap between theory and observations

description: In the 1980s, three related impossibility results emerged in the field of distributed computing. First, Fischer, Lynch, and Paterson demonstrated that deterministic consensus is unattainable in an asynchronous message-passing system when a single process may crash-stop. Subsequently, Loui and Abu-Amara showed the infeasibility of achieving consensus in asynchronous shared-memory systems, given the possibility of one crash-stop failure. Lastly, Santoro and Widmayer established the impossibility of consensus in synchronous message-passing systems with a single process per round experiencing send-omission faults.
 In this paper, we revisit these seminal results. First, we observe that all these systems are equivalent in the sense of implementing each other. Then, we prove the impossibility of consensus in the synchronous system of Santoro and Widmayer, which is the easiest to reason about. Taking inspiration from Völzer's proof pearl and from the Borowski-Gafni simulation, we obtain a remarkably simple proof.
 We believe that a contemporary pedagogical approach to teaching these results should first address the equivalence of the systems before proving the consensus impossibility within the system where the result is most evident.

"Non-stop ecstatic dancing": An ethnographic study of connectedness and the rave experience in central Canada
Creators: name: Olaveson, Tim
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Anthropology, Cultural.

description: In this thesis I examine the rave experience in central Canada. More specifically, I investigate in detail the experience that rave's around the world have called connectedness. I begin by describing the historical antecedents to rave, which trace back much farther than most people believe. Moving through acid rock, disco, the Northern soul scene, New York garage, Chicago house, and Detroit techno, I then describe acid house---rave's immediate predecessor---and its technological quantum leaps, electronic and chemical. Discussing its roots on the island of Ibiza and in the popular culture capital of the world, "Madchester," I then trace acid house's explosion into what we now know as rave (despite the fact that the term was passe before the phenomenon had even hit North America). I then review the literature on rave culture, which falls into two broad categories: sociology and cultural studies. Finding most of these analyses lacking due to their underlying epistemological foundations and resultant methodological approaches, I illustrate how the most fruitful approach to studying rave, especially the rave experience, is an experiential one. After outlining the fundamental tenets and some methodological requirements of experiential anthropology, I describe the methods used in this research. In the following chapter, I provide a multi-sited narrative of the people and places I encountered during field research, with a particular focus on my own lived experience. I then illustrate how some aspects of rave in central Canada allow it to be characterized as a religious or spiritual experience for some participants. I go on to explore the central theme of that experience next---connectedness. Again using my own and my informants' experiences as illustrative, I outline the five key features of connectedness, in the process demonstrating its equivalence with Emile Durkheim's collective effervescence and Victor Turner's communitas. Finally, in the conclusion I pose the questions: What is the teleology of rave? and What is the future of rave? I answer these by returning to Durkheim and Turner, particularly the similar but seldom recognized processual and dialectical understanding of social life inherent in both of their anthropologies.
Analysis of the subcellular trafficking of the glucocorticoid receptor and properties of the ligand binding domain
Creators: name: Ewing, Robyn
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Biology, Cell.
subject: Chemistry, Biochemistry.

description: The glucocorticoid receptor (GR) is a ligand dependent transcription factor and member of the nuclear receptor superfamily. Nuclear import and export of transcription factors is accomplished through nuclear localization signals (NLS) and nuclear export signals (NES), respectively. We have determined that L687 and L690 of rat GR are necessary for the characteristically slow nuclear export of GR and may be included in the signal sequence responsible for directing post-agonist withdrawn GR from the nucleus to the cytoplasm. We also suggest that L687 and L689 of rat GR are required for efficient NL2-mediated nuclear translocation. Substitutions L687A and L689A mildly affect steroid binding and steroid off-rate, yet significantly increase the concentration of steroid required for inducing nuclear import of naive GR. When introduced into GRNL1-, these substitutions compromise the receptor's ability to transfer to the nucleus, suggesting they partially abrogate NL2 activity. We have also observed that NL1-dependent transfer does not begin until 10 -7M steroid, demonstrating that NL2 is the primary physiological mediator of GR nuclear import.

description: Within robotics, areas such as locomotion, unmanned aerial vehicles (UAV's), machine vision, and dexterity of robots intensive research has been performed. In considering the dexterity of robots, work has been done for various types of robots. Also the robotic ability to manipulate or closely mimic the agility of humans has been extensively investigated. Humans are able to do a wide variety of tasks based on the complex series of joints at the wrists. The area of research into robotic wrists has however never attempted to emulate the human wrist. The wrist with its tendons, ligaments, and metacarpals allow three degrees of freedom (DOF's), and this would be extremely advantageous in many scenarios where robots are used. The goal of this thesis was to emulate the human wrist, by conceiving and designing a 3 DOF manipulator which could be easily attached to any robot arm or similar device. The end result of this thesis was to design an easy to implement 3 DOF spherical tendon based manipulator, complete with control system for which the approximate systems response would be known. At the conclusion of the work this was indeed the end result, and all lessons learned are enclosed herein.

description: Active baths are characterized by a non-Gaussian velocity distribution and a quadratic dependence with active velocity $v_0$ of the kinetic temperature and diffusion coefficient. While these results hold in over-damped active systems, inertial effects lead to normal velocity distributions, with kinetic temperature and diffusion coefficient increasing as $\sim v_0^α$ with $1<α<2$. Remarkably, the late-time diffusivity and mobility decrease with mass. Moreover, we show that the equilibrium Einstein relation is asymptotically recovered with inertia. In summary, the inertial mass restores an equilibrium-like behavior.

title: EXPLORING THE ECOSYSTEM SERVICE VALUE AND THE IMPLEMENTATION OF AN ECOSYSTEM SERVICE POLICY APPROACH IN A NORTHERN UK CITY.
Creators: name: Flockton-Meddeman, T
Publisher: name: Liverpool John Moores University
Year: 2020

description: This project aims to identify and engage two main target groups within the Liverpool City Region (LCR): key decision-makers and the public living within LCR. Both are stakeholders within the commentary surrounding green infrastructure within the region. The project broadly aims to explore stakeholder (both public and private) perceptions of urban greenspace within the LCR. It hopes to further the narrative on the application of environmental economics within northern UK cities through implementing ecosystem valuation methodologies within the wider ecosystem service framework. I have taken this opportunity to advance otherwise limited WTP data within low-income communities by choosing a study site in Everton, North Liverpool, ranked amongst the 1% most deprived areas in the country (Urban GreenUp, 2017). The project also looks more broadly at perceptions of an ecosystem service policy approach and the potential for its implementation within the LCR via accessing current knowledge and perceptions from key decision makers within the region. In short, this study broadly looks to generate data fit to inform environmental decision-making within a local, regional and national scale. The project therefore sets out objectives to: • Elicit public values and perceptions of urban greenspace through the development and application of a willingness-to-pay choice contingent study in Everton, North Liverpool. • Fill gaps in research via generating willingness-to-pay data for GI in a low-income community within a northern UK city. • Assess professional knowledge, perceptions, and the potential for implementation of an ecosystem service policy approach, specifically the natural capital approach, within the Liverpool City Region. • Provide context to the wider discussion around future changes in environmental legislation, in term informing the decision-making process at varying levels.

description: The fidelity-based smooth min-relative entropy is a distinguishability measure that has appeared in a variety of contexts in prior work on quantum information, including resource theories like thermodynamics and coherence. Here we provide a comprehensive study of this quantity. First we prove that it satisfies several basic properties, including the data-processing inequality. We also establish connections between the fidelity-based smooth min-relative entropy and other widely used information-theoretic quantities, including smooth min-relative entropy and smooth sandwiched Rényi relative entropy, of which the sandwiched Rényi relative entropy and smooth max-relative entropy are special cases. After that, we use these connections to establish the second-order asymptotics of the fidelity-based smooth min-relative entropy and all smooth sandwiched Rényi relative entropies, finding that the first-order term is the quantum relative entropy and the second-order term involves the quantum relative entropy variance. Utilizing the properties derived, we also show how the fidelity-based smooth min-relative entropy provides one-shot bounds for operational tasks in general resource theories in which the target state is mixed, with a particular example being randomness distillation. The above observations then lead to second-order expansions of the upper bounds on distillable randomness, as well as the precise second-order asymptotics of the distillable randomness of particular classical-quantum states. Finally, we establish semi-definite programs for smooth max-relative entropy and smooth conditional min-entropy, as well as a bilinear program for the fidelity-based smooth min-relative entropy, which we subsequently use to explore the tightness of a bound relating the last to the first.

description: The genetic stability of the rabies glycoprotein (G) expression cassette of AdRG1.3 was examined using both in vitro and in vivo models. For the in vitro study, the AdRG1.3 vaccine was serially passaged 20 times in 293 cell culture and from the twentieth passage a total of 67 AdRG1.3 virus clones were obtained. The G gene expression cassette (including an SV40 polyadenylation signal sequence) along with flanking human adenovirus type 5 sequences were amplified from these clones using PCR to generate an amplified product approximately 2.25 kb long. These products were then purified and subjected to DNA sequence analysis. No changes were observed in the 1870 nucleotide sequence window (containing both the G gene (1572 nt) and the SV40 polyA sequence (132 nt)) of any of the 67 clones. Findings show that the G gene insert is stably expressed in a conformationally appropriate form by the recombinant HAd5 vector. The genetic stability of the G gene cassette of AdRG1.3 was also evaluated upon in vivo passage using five independent series of cotton rats (Sigmodon hispidus). From the fifth in vivo passage of AdRG1.3, a total of 105 virus clones were obtained from these five independent series of animals. The complete G gene expression cassette was amplified from these clones by PCR and sequenced as for the in vitro study; no base changes were observed in the targeted 1870 nucleotide sequence window of any of these clones. Therefore, these results show that the G gene expression cassette of AdRG1.3 remains stable within the adenovirus vector upon passage of the vaccine both in cell culture and in animals.

description: This thesis presents an Artificial Neural Network Research Framework (ANN RFW) for predicting medical outcomes. The ANN RFW along with other new and pre-existing applications, and the steps linking them are presented as part of an Outcome Prediction Model Definition Process (OPMDP). Proof-of-concept experiments are performed on three outcomes from two Canadian Neonatal Network (CNN) databases. Successful results were obtained from the ANN RFW and a number of the subsequent applications. Results obtained using an ANN plus case based reasoner (CBR) were not yet favourable. In one of the intermediary steps, a modified method for extracting relative importance of ANN inputs was developed. The resulting relative weight results indicated that the importance of input variables of continuous outcomes may vary over the course of outcome's duration. Observing relative weights for three outcomes indicated that each outcome must have its own prediction model.
Effect of various biogeochemical processes on mercury methylation in copper-zinc and gold mine tailings
Creators: name: Stanley, Nicolette
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Biogeochemistry.

description: Mercury is a well known environmental pollutant. Anthropogenic sources include coal combustion, waste incineration and metal processing. In base metal mines, Hg is often left in the mining wastes (i.e., mine tailings). Once disposed of in open-air impoundments, these Hg-containing tailings can undergo various biogeochemical transformations, including Hg methylation. It is the methylated form of mercury (MeHg) that poses a threat to the environment, because it bio-accumulates at each level of the food chain. The present study was undertaken to assess the biogeochemical factors affecting Hg methylation in Cu-Zn and Au mine tailings. The study focused on the role of sulfate-reducing bacteria (SRB) because they are suspected to be associated with Hg methylation. Temperature, sulfate and organic carbon availability, along with SRB activity were tested as potential factors affecting Hg methylation in column experiments containing old Au tailings and fresh Cu-Zn tailings. The results first showed that SRB activity did not enhance Hg methylation in Cu-Zn tailings and Au tailings, indicating that iron reducing bacteria, and not SRB, along with abiotic methylation reactions played an important role. Cold temperatures did not slow down SRB activity and MeHg production, but the accidental freezing and thawing of the Cu-Zn tailings promoted the production of soluble MeHg. The mechanism responsible for this unexpected Hg methylation is however unknown. Elevated organic carbon and sulfate concentrations did enhance SRB activity, but not MeHg formation in the tailings, because increased sulfide production hindered Hg methylation. Tailings mineralogy played a significant role in the production of methyl mercury, Au tailings contained more soluble and solid-bound MeHg than Cu-Zn tailings. These results add to the increasing amount of information on Hg cycling in the environment, and indicate that SRB might not be the dominant Hg methylators in mining environments.

description: Keeping sensing coverage while saving energy of wireless sensor network is one of major challenges in wireless sensor network which includes three fundamental research aspects: coverage discover methods, conflict resolve algorithm and wakeup strategy. By means of computing geometry and computer graphics some solutions proposed for the wired sensor network were transplant to the wireless sensor network. However, the heavy message overhead and the centralized model made most of them can not gracefully handle the more restrict conditions in the wireless sensor network to resolve Coverage Problem. In this thesis, we propose efficient coverage-preserving and energy-conserving protocols for wireless sensor networks. We discuss our protocols and their implementation using ns-2 simulator. We also present an extensive set of simulation experiments to evaluate their performance using several scenarios.

description: Wireless networks were first developed in the 1970s, and people's interest in them has been growing ever since. A broad range of differing capabilities is covered by wireless technologies and is oriented toward different uses and needs. In this thesis, we propose a novel application architecture based on wireless networks and designed for museums to allow visitors, especially group of visitors, to have an attractive tour experience. While current museum visiting's approaches are largely interactive but have a number of disadvantages, this application utilizes mobile devices as facilities to help visitors benefit not only from visiting a real museum environment but at the same time enriching their ability to search for additional material. Moreover, as it provides powerful functions, the application will enable visitors to establish a virtual community platform by which they will be able to communicate and share information through wireless networks.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: This study introduces a novel methodology for the design of the proppant pumping schedule for a hydraulic fracture, in which the fi nal proppant distribution along the crack is prescribed. The method is based on the assumption that the particles have relatively small impact on the fracture propagation, unless they reach the tip region. This makes it possible to relate the proppant velocity to the clear fluid velocity inside the fracture, which is calculated assuming no proppant. Having the history of the clear fluid velocity distribution, the prospective proppant motion can be computed. Then, volume balance is used to relate the final concentration at some point inside the fracture to the corresponding input concentration at a speci fic time instant, which helps to avoid solving an inverse problem. One exceptional feature of the approach lies in the fact that it is applicable to multiple fracture geometries and can be implemented using various hydraulic fracturing simulators. To verify the technique, two fracture geometries are considered - Khristianovich-Zheltov-Geertsma-De Klerk (KGD) and pseudo-3D (P3D). It is shown that the developed approach is capable of properly estimating the pumping schedule for both geometries. In particular, the proppant placement along the fracture at the end of the pumping period, calculated according to the adopted proppant transport model, shows close agreement with the design distribution. The comparison with Nolte's scheduling scheme shows that the latter is not always accurate, and cannot capture the essential di fferences between the schedules for the fracture geometries considered.

Female visual artists' perspectives on creativity and creative talent development: Obstacles and opportunities

description: The purpose of this study was to gain insight into creativity and creative talent development in order to address the problem of underachievement of creatively talented females. The experiences of ten female visual artists were investigated from a feminist, interpretive perspective using open-ended interviews and a focus group, which was observed by a reflecting team. Using grounded theory, the data analysis identified seven themes. The themes are: educational experiences, urge to create, gender issues, talent is not enough, connections, obligations and expectations, and need for support. Results revealed that talent alone is not enough to ensure realization of potential. A variety of supports are critical to the development of talent. Strategies to promote talent development included mentor programs and career-training programs specific to the needs of creatively talented females. There is also a need to provide professional development for teachers in both art and creativity. A further result demonstrated that while life and work may, at times be distinct, they are not separate. They are inextricably linked and influence each other in reciprocal ways. As such, in determining how to support talent development, one must consider supporting life choices. A model of creative female talent development was developed to represent the intersection and influence of professional and personal lives of the participants. It is in the form of the two rails that make up the double helix framework of the DNA molecule. One rail represents aspects of personal life and the other rail represents career components of creatively talented females. The rails connect the various parts of a life together. The rails are meant to convey the fact that the career development of creatively talented females is not a linear process. There may be many ups and downs, twists and turns. The two strands are ultimately connected and, as such, events or developments in one area, can affect the other.

Three essays on environmental economics: Remanufacturing, Movements of Waste, and Democracy

description: Chapter 1: Remanufacturing: Remanufacturing is a form of recycling where used durable goods are refurbished to a condition comparable to new products. With reduced energy and resource consumption, remanufactured goods are produced at a fraction of the original cost and with lower emissions of pollution. This paper presents a theoretical model of remanufacturing where a duopoly of original manufacturers produces a component of a final good. The component needing to be replaced creates an aftermarket. An environmental regulation assessing a minimum level of remanufacturability is also introduced The main results indicate that a social planner could use collusion of the firms on the level of remanufacturability as a substitute for environmental regulation. However, if an environmental regulation is to be implemented, collusion should be repressed since competition supports the public intervention better. One of the results also coincides with the Porter Hypothesis. Chapter 2: Transboundary movements of waste: In a stylized model of international trade, a monopolist in the North exports second-hand products to a representative firm in the South to be reused as intermediate goods, with potential trade gains. The degree of reusability of waste products is a crucial choice variable in the North. This is because with a lack of international vigilance, non-reusable waste can be mixed illegally with the reusable waste. I explore the driving forces for the movement of illegal waste, paying particular attention to the role of local waste regulations, such as the EU's Waste Electrical and Electronic Equipment directive. Under mild conditions, it is shown that increased regulation stringency in the North leads its firm to reduce the degree of reusability of its products. As a result, the flow of non-reusable waste to the South increases, providing another channel for the Pollution Haven Hypothesis. Chapter3: Is Democracy good for the environment? The role of private mitigation efforts: We study the question posed in the title in the context of open economies where trade and welfare depend on the extent to which regulation permits the environment to be used as an input in production, and where individuals may privately mitigate the consequences of pollution at a cost. Governments may also manage the openness of the economy to trade directly as well as indirectly via environmental regulation. In this framework, we compare the degree of regulatory stringency and the level of pollution that emerge in the equilibria of a set of political regimes that range from autocratic to fully competitive or democratic. The answer to the question is not straightforward in this investigation because many well-off-citizens in democratic countries may prefer the higher gross incomes that come with freer trade and unregulated production.

Proppant transport in hydraulic fracturing : crack tip screen-out in KGD and P3D models

description: The aim of this study is to develop a model for proppant transport in hydraulic fractures capable of capturing both gravitational settling and tip screen-out effects, while prohibiting the particles from reaching the crack tips by imposing a width restriction based on the particle size. First, the equations that govern the propagation of hydraulic fractures and the proppant transport inside them are formulated. They are based on the solution for the steady flow of a viscous fluid, mixed with spherical particles, in a channel, which is obtained assuming an empirical constitutive model. This proppant transport model is applied to two fracture geometries – Khristianovich-Zheltov-Geertsma-De Klerk (KGD) and pseudo-3D (P3D). Numerical simulations show that the proposed method makes it possible to capture proppant plug formation and growth, as well as the gravitational settling for both geometries. A dimensionless parameter, whose magnitude reflects the intensity of the settling, is introduced for the P3D fracture. [The previous file was updated 2014-08-13 to reflect changes to publication].
