description: Here, we tested whether phylogenetic and morphological distance correlate with trophic niche overlap using a path analysis of multiple partial regression of distance matrices. We also tested whether niche breadth and overlap changed with inclusion of prey availability and morphological similarity by using a recently proposed metric. To our knowledge, this is the first study using this approach to an amphibian community.

Tribe in slums

description: Background: Urbanization is increasing around the world, and in India this trend has translated into an increase in the size of slum dwellings. Slum environments may have a negative effect on human health, in particular women’s health. The objective of the study is to determine factors associated with Indian women’s health in slum environments. Methods: The relationship between women’s health, measured by BMI, and demographic, behavioural, and socioeconomic factors was statistically modelled. A multiple linear regression was performed, using data from the India National Family Health Survey. Results: Increasing BMI is significantly and positively associated with: frequency of watching television, having diabetes, age, wealth index, and residency status in the areas of New Delhi, Andhra Pradesh or Tamil Nadu. Conclusion: While belonging to a scheduled tribe was not associated with changes in BMI, unadjusted rates suggest that tribal status may be worthy of deeper investigation. Among slum dwellers, there is a double-burden of under-nutrition and over-nutrition. Therefore a diverse set of interventions will be required to improve the health outcomes of these women.

description: The excitation of surface plasmons on metallic nanoparticles has the potential to significantly improve the performance of solar cells, in particular thin-film structures. In this article, we investigate the effect of the dielectric spacer layer thickness on the photocurrent enhancement of 2 μm thick, thin-film poly-Si on glass solar cells, due to random arrays of self assembled Ag nanoparticles deposited on the front or the rear of the cells. We report a strong asymmetry in the external quantum efficiency (EQE) of the cell for front and rear located particles for different spacer thicknesses, which is attributed to differences in the scattering behavior of the nanoparticles. We find that for random arrays, with spectrally broad scattering resonances, the strength of the driving field and the coupling efficiency are more important for light trapping than the resonance wavelength. For particles located on the front of the cells it is desirable to have a thin dielectric spacer layer to enhance the scattering from the Ag nanoparticles. Additionally, light trapping provided by the random sized particles on the front can overcome suppression of light transmitted in the visible wavelength regions for thin layers of Si, to result in overall EQE enhancements. However, for particles deposited on the rear it is more beneficial to have the particles as close to the Si substrate as possible to increase both the scattering and the coupling efficiency.

description: The purpose of this qualitative, exploratory study was to develop a deeper understanding of educational and other social experiences and relationships of post-secondary students who were clinically diagnosed with primary obsessive-compulsive disorder (OCD). The researcher also investigated their strengths, weaknesses, coping strategies, and quality of life through mental and physical health. The majority of people with OCD have obsessions and compulsions that last greater than an hour each day or severely impact daily life. Obsessions are irritating feelings or mental pictures that individuals try to block or mitigate with irrational physical or mental compulsions, often appearing as excessive hand washing in reaction to a contamination obsession. Participants comprised seven university students who completed three self-report questionnaires and two semi-structured interviews with the researcher. Five participants submitted self-report journals. These data were examined using interpretative phenomenological analysis (IPA).The present study advanced previous research as it documented extensive lifelong characteristics, experiences, and relationships from these students. It yielded salient findings related to their OCD functional impairment and quality of life. Further, it showed that as students, their intellectual integration seemed to play a greater role in academic persistence than did their social integration. In addition, participants’ university policy and practice recommendations were congruent with a similar study from about a decade ago indicating that perhaps few or none of the past recommendations were implemented for the benefit of such students. Present recommendations should be implemented accordingly.
German health-related environmental monitoring

description: The German system of a health-related environmental monitoring is based upon two instruments: The German Environmental Survey (GerES) and the Environmental Specimen Bank (ESB). The ESB is a tool to describe time trends of human exposure. Each year approx. 500 students from 4 sampling locations are analysed for their heavy metal contents in blood, blood plasma, and urine. GerES is a nationwide representative cross-sectional study that has been conducted four times up to now. Both instruments have been used to measure heavy metals over the last decades and thus provide complementary information.Both instruments are useful to describe time trends. However, combining the two has an added value, which is demonstrated for heavy metals for the first time in this paper. Major results and the changing importance of sources of exposure to heavy metals (Pb, Cd, Hg, Au, Pt, U and Ni) are shown. This leads to the following conclusion about the today's relevance of exposure in Germany. For the study participants of the city of Muenster, lead in whole blood decreased from about 70 ìg/l in 1981 to levels below 15 ìg/l in 2009. GerES data of young adults confirmed this time trend and GerES IV on children revealed the decreasing relevance of lead in outdoor air and in drinking water. The concentrations of mercury in urine decreased because in Germany it is no longer recommended to use amalgam fillings for children. However, GerES IV and ESB data also demonstrate that despite the decline of these heavy metals exposures to nickel and uranium originating from drinking water are still of importance.Quelle: International Journal of Hygiene and Environmental Health xxx (2013), S.1

description: Quantum Approximation Optimization Algorithms (QAOA) have been actively developed, among which Fermionic QAOA (FQAOA) has been successfully applied to financial portfolio optimization problems. We improve FQAOA and apply it to the optimization of electricity demand portfolios aiming to procure a target amount of electricity with minimum risk. Our new algorithm, FQAOA-SCLFM, allows approximate integration of constraints on the target amount of power by utilizing self-consistent local field modulation (SCLFM) in a driver Hamiltonian. We demonstrate that this approach performs better than the currently widely used $XY$-QAOA and the previous FQAOA in all instances subjected to this study.

Binaural Beamforming

description: In binaural hearing aids, several beamforming algorithms can be used. These beamformers aim to enhance the target speech signal and preserve the binaural cues of the target source (e.g. with constraints on the target). However, the binaural cues of the other directional sources as well the background noise are often lost after processing. This affects the global impression of the acoustic scene, and it limits the perceptual separation of the sources by the hearing aids users. To help the hearing aids users to localize all the sound sources, it is important to keep the binaural cues of all directional sources and the background noise. Therefore, this work is devoted to find the best trade-off between the noise/interferers reduction and the cues preservations not only for the directional interferers but also for the background noise based on selection and mixing processes. In this thesis, some classification decision algorithms, which are based on different criteria such as the power, the power difference, and the coherence, are proposed to complete the selection and mixing processes. Simulations are completed using recorded signals provided by a hearing aid manufacturer to validate the performance of the proposed algorithm under different realistic acoustic scenarios. After detailed testing using different complex acoustic scenarios and different beamforming configurations, the results indicate that some of the proposed classification decision algorithms show good promise, in particular the classification decision algorithm based on coherence.

description: (1) Background: Arbuscular mycorrhizal (AM) fungi are symbiotic organisms that help plants acquire nutrients from the soil in exchange for photosynthetic carbon. Commercial AM fungal inoculants are widely available and are used extensively in agriculture including wine grape production. However, positive growth responses from inoculants are more consistent in the greenhouse compared to the field. (2) Methods: We grew three grapevine rootstocks with and without an AM fungal inoculant in the greenhouse for one year, then they were transplanted to the field for two years. To quantify the establishment of the inoculant, we analyzed root samples with a digital PCR assay. (3) Results: We show that AM fungal inoculation increased biomass production only in the greenhouse. After two growing seasons in the field, the commercial inoculant colonized roots but did not increase biomass production compared to uninoculated rootstocks. (4) Conclusions: This study highlights that AM fungal inoculants do not always promote growth of grapevines in the field. Future research should focus on inoculant strains designed for viticulture applications and take rootstock into consideration to maximize their efficacy.

description: As work-integrated learning (WIL) becomes embedded in the higher education sector, it presents an unprecedented opportunity for practitioners to learn from one another. The challenges of implementing a WIL program are widely known among the WIL community. These challenges often relate to the flexibility and diversity afforded models both within and between institutions. Many institutions have begun internally sharing practices; however, missing in the literature is circulation of this information to facilitate learning across domains. This paper is positioned in the nexus of WIL cross-institutional dissemination. It is hoped that this paper will achieve two aims, the dissemination and application of an Australian regional WIL model. First, a regional Internship Program is detailed through the key areas of purpose, pedagogy, processes, design and assessments. Second, application of the model is offered through an empirical examination of students' reflections.

description: SARS-CoV-2, which causes the Coronavirus Disease 2019 (COVID-19) pandemic, has a brain neurotropism through binding to the receptor angiotensin-converting enzyme 2 expressed by neurones and glial cells, including astrocytes and microglia. Systemic infection which accompanies severe cases of COVID-19 also triggers substantial increase in circulating levels of chemokines and interleukins that compromise the blood-brain barrier, enter the brain parenchyma and affect its defensive systems, astrocytes and microglia. Brain areas devoid of a blood-brain barrier such as the circumventricular organs are particularly vulnerable to circulating inflammatory mediators. The performance of astrocytes and microglia, as well as of immune cells required for brain health, is considered critical in defining the neurological damage and neurological outcome of COVID-19. In this review, we discuss the neurotropism of SARS-CoV-2, the implication of neuroinflammation, adaptive and innate immunity, autoimmunity, as well as astrocytic and microglial immune and homeostatic functions in the neurological and psychiatric aspects of COVID-19. The consequences of SARS-CoV-2 infection during ageing, in the presence of systemic comorbidities, and for the exposed pregnant mother and foetus are also covered.

Numerical investigation of turbulence generation in non-breaking potential waves
Creators: name: Babanin, Alexander
name: Chalikov, Dmitry
Publisher: name: Swinburne
Year: 2024

description: Theoretically, potential waves cannot generate the vortex motion, but the scale considerations (Babanin, 2006) indicate that if the steepness of waves is not too small, the Reynolds number can exceed the critical values. This means that in presence of initial non-potential disturbances the orbital velocities can generate the vortex motion and turbulence. This problem was investigated by means of linear-instability theory (Benilov et al, 1993). It was shown that pure two-dimensional motion always remains potential because one-dimensional vortex (in vertical plane) does not interact with the orbital motion. The waves can generate the vortex in horizontal plane, and further development of vorticity occurs due exchange of energy between the components of vorticity. Then, due to non-linearity, motion at smaller scales and more or less developed turbulent regime arises.

description: The population of seniors in Canada is increasing, and the numbers of seniors who remain in or return to the workforce rather than retire are also on the rise. However, work experiences of older individuals have been understudied in research. This study explores the meaning of work to a group of individuals over age 65 in Thunder Bay, a city in Northwestern Ontario. The researcher conducted ten interviews following phenomenological methods of inquiry. Using identity theory, life course perspective, and continuity theory, the study also sought to understand the importance of continuity to older individuals’ experiences of work. Findings revealed eight themes that influenced older workers’ experiences: socio-historical trends, the work environment, health, financial circumstances, purpose, choice, life beyond work, and perceptions of age. Ultimately, continuity of behaviours, life stories, and self-understandings are important features of older workers’ experiences and may influence whether this important group will continue to work.

description: Wavelength reuse techniques for bidirectional ultra-wide band (UWB) over fiber (UWBoF) networks are presented. The downstream optical signal from the central station (CS) is reused for upstream data transmission with the original data erased at the base station (BS). Two wavelength reuse schemes for the generation of a clear optical carrier at the BS are theoretically analyzed and experimentally demonstrated. In the first scheme, the wavelength reuse is based on phase-modulation to intensity-modulation (PM-IM) conversion and destructive interferencing using a polarization modulator (PolM) and a fiber Bragg grating (FBG). A theoretical analysis is performed which is verified by an experiment. In the second scheme, the wavelength reuse is based on injection locking of a Fabry–Pérot laser diode (FP-LD) and polarization multiplexing. The UWB injection signal contributes to better BERs of both downstream and upstream services and a lower power penalty cause by the wavelength reuse of the whole system than the baseband signal. A bidirectional point-to-point transmission of over a 25-km single-mode fiber (SMF) using a single wavelength from the CS in each scheme is demonstrated.

description: Background: GMC1 (2-(1H-benzimidazol-2-ylsulfanyl)-N-[(Z)-(4-methoxyphenyl) methylideneamino] acetamide) effectively inhibits androgen receptor function by binding directly to FKBP52. This is a novel mechanism for the treatment of castration resistant prostate cancer (CRPC). Methods: an LC-MS/MS method was developed and validated to quantify GMC1 in plasma and urine from pharmacokinetics studies in rats. An ultra-high-performance liquid chromatography (UHPLC) system equipped with a Waters XTerra MS C18 column was used for chromatographic separation by gradient elution with 0.1% (v/v) formic acid in water and methanol. A Sciex 4000 QTRAP® mass spectrometer was used for analysis by multiple reaction monitoring (MRM) in positive mode; the specific ions [M+H]+m/z 340.995 → m/z 191.000 and [M+H]+ m/z 266.013 → m/z 234.000 were monitored for GMC1 and internal standard (albendazole), respectively. Results: GMC1 and albendazole had retention times of 1.68 and 1.66 min, respectively. The calibration curves for the determination of GMC1 in rat plasma and urine were linear from 1–1000 ng/mL. The LC-MS/MS method was validated with intra- and inter-day accuracy and precision within the 15% acceptance limit. The extraction recovery values of GMC1 from rat plasma and urine were greater than 95.0 ± 2.1% and 97.6 ± 4.6%, respectively, with no significant interfering matrix effect. GMC1 is stable under expected sample handling, storage, preparation and LC-MS/MS analysis conditions. Conclusions: Pharmacokinetic evaluation of GMC1 revealed that the molecule has a biexponential disposition in rats, is distributed rapidly and extensively, has a long elimination half-life, and appears to be eliminated primarily by first order kinetics.

description: Cette thèse rend audibles les paroles des enfants-acteurs colligés alors qu’ils vivaient le processus de choix scolaire dans le moment de transition entre paliers élémentaire et secondaire. L’intérêt particulier du projet pour le choix de la langue d’instruction en milieu minoritaire utilise la pertinence d’une étude comparée internationale pour mieux comprendre les particularités et similarités du vécu des enfants de la Corse et de l’Ontario, deux territoires fortement marqués par les questions sociolinguistiques. L’approche postule avec efficience que la mise en perspective des contextes peut contribuer à l’émergence de réflexions et d’actions communes propres à favoriser l’apaisement des conflits ou des tensions, l’harmonisation culturelle sur des territoires multilingues et les droits des enfants en situation minoritaire. Par cette étude de cas de type ethnographique critique, la recherche croise un ensemble d’outils méthodologiques : l’observation participante, le questionnaire et l’entrevue semi-dirigée, ainsi qu’une analyse des contextes scolaire, familial et national. Une analyse sociologique et comparative rigoureuse met en lumière les ressources des enfants en tant qu’acteurs sociaux et les contraintes qui structurent leurs actions. On peut constater que le processus de choix scolaire présente tout à la fois une convergence des construits sociaux que sont les métiers d’élève, d’enfant et d’enfant-citoyen et l’occasion pour les enfants d’agir sur ces construits dans l’édification du projet personnel de chacun. À ce titre, l’analyse des silences des adultes fait poindre le besoin de mieux accompagner les enfants au cours des processus de choix et de transition scolaire, de mieux informer les parents concernant ces processus et de repenser l’éducation civique en milieu minoritaire, le tout pour favoriser et renforcer le respect des paroles des enfants. Cette thèse pluridisciplinaire en sciences de l’éducation offre un nouvel éclairage sur la façon dont les enfants vivent le processus de choix de langue d’instruction en milieu minoritaire, une problématique très peu explorée jusqu’ici dans la recherche internationale. La thèse souligne en outre l’urgence pour les leaders pédagogiques de prendre connaissance de ces problématiques liées à la parole des enfants tout en soulignant la carence d’outils mis à leur disposition pour faciliter leur expression, opérationnaliser leurs droits et participer activement à leur processus de choix.

Dans le champ de recherche sur la prise en compte de la diversité ethnoculturelle dans l’enseignement des sciences de la province, aucune attention n’a été accordée à l’analyse du contenu des manuels scolaires, et ce, en dépit du rôle central que le manuel joue dans la détermination et la structuration des savoirs enseignés et dans la représentation que les élèves ont des sciences. Notre étude vise tout d’abord à dresser une première évaluation de la place réservée à la diversité ethnoculturelle dans les manuels scolaires de sciences de l’Ontario. Elle permet aussi d’incorporer, dans la littérature scientifique, une recherche sur la diversité ethnoculturelle des manuels scolaires qui, contrairement aux études semblables menées à l'extérieur de la province, ne se limite pas aux perspectives autochtones et à l’analyse d’images. C’est ainsi que notre étude a pour fondement la question de recherche suivante : de quelle manière est-ce que la diversité ethnoculturelle est prise en compte dans les manuels de sciences de langue française du secondaire de l’Ontario? Afin de répondre à cette question, nous avons mené une analyse de contenu qualitative de deux manuels de sciences de langue française de 9e et de 10e approuvés par le ministère de l’Éducation de l’Ontario. Cette analyse s’appuie sur la typologie des approches de l’éducation multiculturelle de Banks (1999) qui encourage l’intégration de diverses perspectives culturelles et préconise la sensibilisation aux réalités auxquelles sont confrontés les peuples minoritaires. Les résultats de la présente étude révèlent que les manuels renferment de nombreux contenus ethniques. En revanche, une place négligeable serait réservée aux connaissances scientifiques actuelles des pays non occidentaux et aux contributions des peuples non occidentaux au savoir scientifique contemporain.

description: This project studied the physical and chemical effects of typical impurities on CO2 storage using both experimental approaches and theoretical simulation. Results show that the presence of typical non-condensable impurities from oxyfuel combustion such as N2, O2, and Ar resulted in lower density than pure CO2, leading to decreased CO2 storage capacity and increased buoyancy in saline aquifers. In contrast, inclusion of condensable SO2 in CO2 resulted in higher density than pure CO2 and therefore increased storage capacity. These impurities also had a significant impact on the phase behaviours of CO2, which is important to CO2 transportation. Different effects on rock chemistry were detected with experimental systems containing pure CO2, CO2 with SO2, or CO2 with SO2 and O2 under conditions simulating that in a potential storage site. An equation was proposed to predict the effects of the rock chemistry on the porosity of rocks.

description: This work reports the synthesis of silver nanoparticles (AgNPs) using aqueous extract of Plumbago auriculata, and evaluates their antibacterial and larvicidal activities. The synthesized silver nanoparticles were characterized by various spectroscopy techniques, such as FTIR, XRD, TEM, EDX, Zeta potential, and DLS. The synthesized AgNPs exhibited significant antibacterial activity against Gram-positive and Gram-negative bacteria, such as Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae. Furthermore, synthesized nanoparticles inhibited the fourth instars larvae of Aedes aegypti and Culex quinquefasciatus at the concentration of 45.1 and 41.1 µg/mL respectively. Results of dose-dependent studies showed that synthesized nanoparticles were also effective at low concentrations. Molecular docking studies performed with the salivary protein and odorant-binding protein of Aedes aegypti and Culex quinquefasciatus demonstrated that the naphthoquinone compound plumbagin exhibited reliable binding affinity towards the two enzymes. The findings thus reveal that the plant extract and its nanoparticles can be a better alternative to available chemicals to control mosquitos.

Coincidentally, that spring saw the most destructive flood the settlement had ever known. Lambert was immediately inducted into the Society by his mother, Mme Lepage, who practiced capnomancy and kept a pair of female Dobermans in the basement of the family home. On May 10th, 1994, when Lambert was five years old and despite his mother’s recommendations, he opened his eyes during the solar eclipse, burning them instantly. From the smoke, Mme Lepage divined a future flood that would engulf the mountain. 2. A narrative device. 3. LE GRAND SALON, wherein the Society ritualistically performed Lambert’s demise at each partial solar eclipse, staring at the skies until they could see no more. Presented here is the facsimile of such a ritual, including an Oculists statuary.

description: Children living in foster care are a particularly vulnerable group of children that are at high-risk for experiencing a multitude of difficulties, including poor academic performance and achievement. Although the academic underachievement of foster children has been well-documented for decades, very few attempts have been made to address the problem. This thesis is the second study to come out of the RESPs for Kids in Care research project, which represents one of three known randomized controlled trials aimed at providing an academic intervention to foster children with a view of improving their basic skills, increasing their chances of graduating from high school and enrolling in post-secondary education. Sixty-four foster children (aged 6 to 13 years), recruited from nine Children’s Aid Societies in Ontario, Canada, participated in the project and received an individualized direct-instruction tutoring intervention that was delivered by their foster parent(s). The unique contribution of the current study was its investigation of differential gender effects of the tutoring amongst the foster boys and girls, and whether there were any mental health and social-relational spillover effects. A mixed-method approach was used to explore these differential effects and the main hypothesis of the project, that the foster children in the experimental group would demonstrate greater gains in reading and math than the children in the control group, between pre-test and post-test, regardless of gender. The results were promising: the foster children in the experimental group demonstrated significant gains in their basic reading and math skills after receiving the foster-parent delivered one-on-one tutoring; there were differential gender effects across the academic and mental health results; and there was partial support for the notion that an academic tutoring intervention does elicit spill-over effects into the mental health and social-developmental domains of foster children’s lives. Results and implications were discussed.

description: This study investigates variable positioning of adverbs in compound verb tenses in vernacular Quebec French using the sociolinguistic framework of Variation Theory (Weinreich et al. 1968; Labov 1969). While variable adverb placement is addressed in both the prescriptive and linguistic literature, whether their explanations for it hold in practice remains to be determined; quantitative research of this phenomenon in usage-based corpora is limited, and rare in French. The research objectives are therefore to determine the productivity of variable adverb placement in French in these verbal contexts, to uncover the linguistic and/or social factors which constrain it, and to evaluate the extent to which current treatments of this variable in the literature accurately reflect what occurs in speech. Data is thus extracted from a corpus of spontaneous discourse, is coded for several linguistic and social factors, and is quantitatively analysed using standard variationist methodology (Poplack & Tagliamonte 2001). Overall rates of variant use suggest that variable adverb placement is robust, with adverbs occurring just slightly more frequently after the past participle than between the auxiliary and the participle; placement at the beginning of the sentence is rare. The results of the distributional and multivariate analyses largely confirm the purported conditioning effects of the tested linguistic factors, suggesting that prescriptive and theoretical linguistic approaches are generally correct in their accounts of this phenomenon. However, closer investigation reveals these effects to be sensitive to the lexical identity of the adverb, namely, their particular placement preferences; once these positioning predilections are taken into consideration, the conditioning effects of the linguistic factors essentially disappear. Sociodemographic factors are also found to be mildly implicated in variable adverb placement, and these too are sensitive to the influence of the lexical identity of the adverb. Ultimately, it is argued that this variable is primarily lexically-constrained, a finding which can be only minimally and indirectly inferred from the relevant literature. Taken together, the results of this study provide new and vital insight into the mechanisms underlying variable adverb placement in French, and also highlight the importance of quantitatively investigating such variable language phenomena in corpora of vernacular speech.

description: Mitochondria exist in a dynamic network whereby fusion and fission events are critical to the health of the mitochondria, the cell, and the organism. Dysfunctional mitochondrial dynamics underlie a plethora of diseases including various cancers, heart diseases, diabetes, neurodegenerative diseases, and a number of mitochondrial disorders. Despite a strong molecular knowledge of a handful of functional mediators of mitochondrial dynamics, much less is known about how this process is regulated at a cellular level, and what genes are involved in signaling pathways. A previously completed mitochondrial morphology genome screen was repeated with an automated confocal microscope resulting in the identification and validation of MTX2 as a novel regulator of mitochondrial dynamics. Functional characterization of the role of MTX2 in mitochondrial dynamics will further our understanding of mitochondrial biology, and has the future potential to inform therapies for some of the many diseases underscored by dysfunctional mitochondrial dynamics.

description: Obesity has become a worldwide problem that most countries are trying to fight. It affects many people, irrespective of age, race, gender, or religion; anyone can suffer from obesity, which leads to serious problems, both for individuals and for society as a whole. In this study we have selected two groups of people: the basic people who do not exercise on a weekly basis, and the average people who exercise regularly, every week. We have explored the attitude of the two groups in regards to mixing exercises with games, in order to motivate the people with basic activity levels to exercise more frequently. We have used a qualitative standard online questionnaire from AttrakDiff, which evaluates user experience through four important aspects: a) quality; b) subjective understanding of quality and subjective evaluation of quality; c) pragmatic and hedonic features; and d) emotional and behavioural effects. We also did a qualitative study and a quantitative study of some of the important factors present during exercise. The results of the qualitative and quantitative studies were very encouraging as they revealed that mixing games with exercise can transform boring exercises into entertaining ones. It can also motivate players to continue and repeat the exercises. The ANOVA test was applied and it shows that combining games with a stationary bike has a significant effect on the speed and the average rotation per minute of the participants.
Building “21st Century Sewer Socialism”: Sanitation and Venezuela’s Technical Water Committees

description: This thesis assesses the potential of Venezuela’s technical water committees (mesas técnicas de agua, MTAs) to address governance and logistical challenges for improving sanitation in the barrios (low income settlements) of Caracas. The MTAs are a radical experiment in urban planning whereby beneficiary communities map their own water and sanitation needs and help to plan infrastructure development, which is financed by the state. In addition to improving services, the MTAs aim to promote “popular” or “citizen power” as part of a broader political transformation, the Bolivarian Process (1999-present). Based on Hickey and Mohan’s (2005) four criteria for “transformative participation,” the paper argues that the MTAs have opened spaces for citizen empowerment and improved services in the barrios; however, participation at the local scale cannot resolve many of the challenges for improving sanitation such as institutional overlap and the financing gap, especially given that sanitation is the least profitable form of service provision in terms of economic and political payoffs.

description: A novel approach to the design of multi-junction solar cells on silicon substrates for 1-sun applications is described. Models for device simulation including porous silicon layers are presented. A silicon bottom subcell is formed by diffusion of dopants into a silicon wafer. The top of the wafer is porosified to create a compliant layer, and a III-V buffer layer is then grown epitaxially, followed by middle and top subcells. Due to the resistivity of the porous material, these designs are best suited to high efficiency 1-sun applications. Numerical simulations of a multi-junction solar cell incorporating a porous silicon compliant membrane indicate an efficiency of 30.7% under AM1.5G, 1-sun for low threading dislocation densities (TDD), decreasing to 23.7% for a TDD of 10^7 cm^-2.

description: Motion segmentation or recovering structure-and-motion (SaM) from images of dynamic scenes plays a significant role in many computer-vision applications ranging from local navigation of a mobile robot to image rendering for multimedia applications. Since in many applications, the exact type of motion and camera parameters are not known, a priori, the fundamental matrix is commonly used as a general motion model. Although the estimation of a fundamental matrix and its use for motion segmentation are well understood, the studies of conditions governing the feasibility of segmentation for different types of motions are largely unaddressed. In this thesis, the feasibility of motion segmentation using the fundamental matrix is analysed. The focus is on a scene including multiple SaMs viewed by an uncalibrated camera. The quantifiable measures for the degree of separation were theoretically derived for the types of motion that are usually seen in practical applications, namely, motion from background, translational motions and planar motions. Sets of condition to guarantee successful segmentation were proposed via extensive experiments, the design of which was based on the Monte Carlo statistical method, using synthetic images. Experiments using real image data were set up and executed to examine the relevance of those conditions to the problems encountered in real applications. The experimental results show the capability of the proposed conditions to correctly predict the outcome of several segmentation scenarios. In addition, they also show that the Monte Carlo experimental results are very relevant to the problems encountered in real applications. In practice, the success of motion segmentation could be predicted via the value of the degree of separation between two motions estimated from obtainable scene and motion parameters. Therefore, the proposed conditions serve as a guideline for practitioners in designing motion segmentation solutions for computer-vision applications.

description: Background Chronic obstructive pulmonary disease (COPD) is an underdiagnosed condition sharing risk factors with lung cancer. Lung cancer screening may provide an opportunity to improve COPD diagnosis. Using Pan-Canadian Early Detection of Lung Cancer (PanCan) study data, the present study sought to determine the following: 1) What is the prevalence of COPD in a lung cancer screening population? 2) Can a model based on clinical and screening low-dose CT scan data predict the likelihood of COPD? Methods The single arm PanCan study recruited current or former smokers age 50–75 who had a calculated risk of lung cancer of at least 2% over 6 years. A baseline health questionnaire, spirometry, and low-dose CT scan were performed. CT scans were assessed by a radiologist for extent and distribution of emphysema. With spirometry as the gold standard, logistic regression was used to assess factors associated with COPD. Results Among 2514 recruited subjects, 1136 (45.2%) met spirometry criteria for COPD, including 833 of 1987 (41.9%) of those with no prior diagnosis, 53.8% of whom had moderate or worse disease. In a multivariate model, age, current smoking status, number of pack-years, presence of dyspnea, wheeze, participation in a high-risk occupation, and emphysema extent on LDCT were all statistically associated with COPD, while the overall model had poor discrimination (c-statistic = 0.627 (95% CI of 0.607 to 0.650). The lowest and the highest risk decile in the model predicted COPD risk of 27.4 and 65.3%. Conclusions COPD had a high prevalence in a lung cancer screening population. While a risk model had poor discrimination, all deciles of risk had a high prevalence of COPD, and spirometry could be considered as an additional test in lung cancer screening programs.
