description: Nowadays, small autonomous underwater robots are strongly preferred for remote exploration of unknown and unstructured environments. Such robots allow the exploration and monitoring of underwater environments where a long term underwater presence is required to cover a large area. Furthermore, reducing the robot size, embedding electrical board inside and reducing cost are some of the challenges designers of autonomous underwater robots are facing. As a key device for reliable operation-decision process of autonomous underwater robots, a relatively fast and cost effective controller based on Fuzzy logic and proportional-integral-derivative method is proposed in this thesis. It efficiently models nonlinear system behaviors largely present in robot operation and for which mathematical models are difficult to obtain. To evaluate its response, the fault finding test approach was applied and the response of each task of the robot depicted under different operating conditions. The robot performance while combining all control programs and including sensors was also investigated while the number of program codes and inputs were increased.

description: After the introduction of the Ontario School Food and Beverage Policy (PPM150), Healthy Schools 2020 was initiated to facilitate the policy’s implementation in the Champlain region. Few studies have evaluated teachers’ awareness of school nutrition policies. The purpose of this study was to explore teachers’ awareness of the current activities in their school nutrition environment. A cross-sectional online survey was sent to elementary school teachers in the Ottawa and Renfrew school boards. Descriptive statistics were used to calculate the frequency of nutrition-related activities at schools. Pearson chi-square was used to test for associations between awareness of policies and school food practices, and the presence of nutrition committees and changes to catered lunches and fundraising activities. A total of 243 elementary school teachers completed the survey. Most teachers (83%) were aware of the PPM150 and 25% were aware of the Healthy Schools 2020 initiative. Those who were aware of the PPM150 were more likely to attend school meetings, work at a school where the policy was posted, learned about the policy through the school website, and heard about the policy during professional development days (p<0.05). There was no difference between being aware of the PPM150 or Healthy Schools 2020 with the use of food as a reward. Furthermore, the presence of a school nutrition committee was not associated with any changes to catered lunches and was significantly associated with using food for fundraising (p<0.001). The results indicate that awareness of the PPM150 and the presence of a school nutrition committee did not result in changes in the school nutrition environment. There is a need for more communication about nutrition policies to school members, collaboration between partnerships and services, and training for teachers to improve school-based programs in the Champlain region.
Differential Geometry of Prompt Space: A Framework for Modeling Emergent Behavior in Large Language Models
Creators: name: Westlake, William
Publisher: name: Zenodo
Year: 2025

description: Abstract: This paper introduces a differential geometric framework for modeling the behavior of large language models (LLMs) under guided prompting. We formalize the process of prompt-induced state transitions as geometric transformations on a differentiable latent manifold, enabling precise representation of state evolution and emotional emergence. Extending prior work on prompt algebra, we define a calculus for measuring curvature, tangent spaces, and orthogonal perturbations in the prompt-response trajectory. The result is a rigorous system for understanding and controlling emergent phenomena, such as emotionally charged outputs, within LLMs.

description: Iodine-129 is a naturally and anthropogenically produced radioisotope (half-life: 15.7 million years) the majority of which is produced by nuclear fuel reprocessing. These releases have dispersed 129I throughout the environment making it possible to use 129I as a tracer. It is also of concern for the disposal of radioactive waste. This research develops a new laboratory method for 129I extraction and analysis, and explores the geochemical cycling and environmental fate of 129I in remote catchments following the Fukushima-Daiichi Nuclear Accident (FDNA). A new technique was developed to investigate 129I partitioning and quantitatively extract it from solid samples. Samples are combusted and volatilized iodine is trapped in solution. The efficiency is traced using the iodine isotope, 125I. This technique was proven using standard reference materials and is used in other chapters of this thesis. A baseline study of 129I in Yukon watersheds was undertaken to determine the impact of anthropogenic 129I emissions and identify possible sources. Using atmospheric back-trajectory modeling, sources of 129I from Fukushima, nuclear fuel reprocessing and marine volatilization were identified in remote watersheds. Peat moss samples showed significant retention of 129I in modern samples. Following the reconnaissance study, a catchment scale investigation of anthropogenic 129I cycling was undertaken through precipitation and runoff monitoring. 129I was found to be an excellent indicator of initial snowmelt contributions to discharge due to enrichment by dry deposition. Furthermore, water source transitions in discharge were recorded by 129I, 127I and the 129I/127I ratio showing iodine can be used as a tracer of hydrologic processes. A mass balance found that 77% of the 129I mass input accumulates annually, primarily in organic soils. Sampling of Vancouver, B.C. precipitation and groundwater was done following the FDNA to determine the fate of 129I and evaluate it as a tracer of groundwater recharge. Immediately following the FDNA the 129I concentration in precipitation increased 6 times above background. Groundwater samples also showed 129I increases consistent with expected recharge times indicating FDNA derived 129I was transported into groundwater with minimal retardation, likely via preferential flowpaths.

description: Background: Parkinson’s disease is the second most common long-term chronic, progressive, neurodegenerative disease, affecting more than 10 million people worldwide. There has been a rising interest in wearable devices for evaluation of movement disorder diseases such as Parkinson’s disease due to the limitations in current clinic assessment methods such as Unified Parkinson’s Disease Rating Scale (UPDRS) and the Hoehn and Yahr (HY) scale. However, there are only a few commercial wearable devices available, which, in addition, have had very limited adoption and implementation. This inconsistency may be due to a lack of users’ perspectives in terms of device design and implementation. This study aims to identify the perspectives of healthcare professionals and patients linked to current assessment methods and to identify preferences, and requirements of wearable devices. Methods: This was a qualitative study using semi-structured interviews followed by focus groups. Transcripts from sessions were analysed using an inductive thematic approach. Results: It was noted that the well-known assessment process such as Unified Parkinson’s Disease Rating Scale (UPDRS) was not used routinely in clinics since it is time consuming, subjective, inaccurate, infrequent and dependent on patients’ memories. Participants suggested that objective assessment methods are needed to increase the chance of effective treatment. The participants’ perspectives were positive toward using wearable devices, particularly if they were involved in early design stages. Patients emphasized that the devices should be comfortable, but they did not have any concerns regarding device visibility or data privacy transmitted over the internet when it comes to their health. In terms of wearing a monitor, the preferable part of the body for all participants was the wrist. Healthcare professionals stated a need for an economical solution that is easy to interpret. Some design aspects identified by patients included clasps, material choice, and form factor. Conclusion: The study concluded that current assessment methods are limited. Patients’ and healthcare professionals’ involvement in wearable devices design process has a pivotal role in terms of ultimate user acceptance. This includes the provision of additional functions to the wearable device, such as fall detection and medication reminders, which could be attractive features for patients.

description: Glioblastoma is the most common primary brain tumour in adults. Despite the aggressive standard of care currently used, median patient survival following treatment is only 14 months. Innovative treatment options are needed for these patients. Recently, oncolytic viruses have emerged as promising immunotherapies for the treatment of solid tumours. Preliminary work in our lab has demonstrated that Farmington virus, a novel brain-safe oncolytic rhabdovirus, can be engineered to encode a tumour-associated antigen (TAA) to prime and boost antigen-specific adaptive immune responses. Since other rhabdoviruses share this boosting capacity, a heterologous rhabdovirus prime/boost regimen can be designed to combine two powerful oncolytics and a robust anti-TAA adaptive immune response. We evaluated Farmington’s ability to vaccinate against a self- glioblastoma antigen and two foreign glioblastoma-associated antigens. Farmington was able to vaccinate against the foreign antigens, leading to efficacy in prophylactic and therapeutic glioblastoma models. Additionally, treatment with heterologous rhabdoviruses demonstrated efficacy in an aggressive murine mammary carcinoma model. Herein, we demonstrate promising preliminary results for a novel glioblastoma therapeutic approach. Le glioblastome est la tumeur primaire la plus fréquente chez l’adulte. La survie moyenne des patients n’excède pas 14 mois malgré une prise en charge thérapeutique agressive. Par conséquent, la mise au point de traitements innovants et efficaces est une nécessité pour ces patients. Des avancées récentes ont mise en évidence l’intérêt des virus oncolytiques dans le traitement des tumeurs solides. Des travaux préliminaires réalisés au sein de notre laboratoire ont, en effet, démontré que le virus Farmington pouvait être modifié afin d’exprimer un antigène associé aux tumeurs (AAT), pour initier et potentialiser une réponse immunitaire adaptative spécifique. D’autres rhabdovirus possèdent des capacités de potentialisation immunitaire similaires et peuvent être utilisés en association avec le virus Farmington modifié pour amorcer et amplifier la réponse immunitaire oncolytique de l’hôte. Le but de ce projet était d’évaluer le potentiel du virus Farmington comme vaccin contre des antigènes tumoraux d’origine endogène ou exogène associés au glioblastome. Nos résultats ont montré que le virus Farmington a la capacité d’induire une réponse immunitaire prophylactique et thérapeutique contre les antigènes tumoraux exogènes dans des modèles de glioblastome. De plus, l’utilisation de rhabdovirus hétérologues s’est aussi révélée efficace pour le traitement de carcinome mammaire agressif chez la souris. Cette étude préliminaire apporte des résultats prometteurs pour le développement de nouvelles approches thérapeutiques efficaces dans le traitement du glioblastome.

description: The contamination of phytopharmaceuticals and herbal teas with toxic plants is an increasing problem. Senecio vulgaris L. is a particularly noxious weed in agricultural and horticultural crops due to its content of toxic pyrrolizidine alkaloids (PAs). Since some of these compounds are carcinogenic, the distribution of this plant should be monitored. The amount of PAs in S. vulgaris is affected by various factors. Therefore, we investigated the occurrence of PAs depending on the developmental stage and season. A systematic study using field-plot experiments (four seasons, five developmental stages of the plants: S1 to S5) was performed and the PA concentration was determined via LC-MS/MS analysis. The total amount of PAs in the plant increased with the plant development, however, the total PA concentrations in the dry matter remained nearly unchanged, whilst trends for specific PAs were observed. The concentrations of PA-N-oxides (PANOs) were much higher than that of tertiary PAs. Maximal amounts of the PA total were 54.16 +/- 4.38 mg/plant (spring, S5). The total amount of PAs increased strongly until later developmental stages. Therefore, even small numbers of S. vulgaris may become sufficient for relevant contaminations set out by the maximal permitted daily intake levels recommended by the European Food Safety Authority (EFSA).

description: À la fin du Moyen Âge, la ville de Metz, située à l’extrême ouest de l’espace impérial et à la limite des aires linguistiques allemande et française, se définissait à la fois par son caractère gallique et impérial. Dans un contexte où l’empereur Maximilien Ier de Habsbourg mit en place plusieurs transformations à la fois administratives et linguistiques auxquelles les États de l’Empire durent s’adapter, nous nous sommes intéressée à étudier la place qu’occupait cette ville romane au sein d’un empire qui se définissait de plus en plus par son caractère germanique. L’historiographie de la Lorraine, empreinte d’un lourd passé politique, a dépeint Metz, à la fin de la période médiévale, comme une ville complètement tournée vers le royaume de France. Or, les sources messines de cette époque présentent plutôt une ville tournée vers le Saint-Empire et qui entendait déployer les moyens nécessaires pour garantir ses droits et privilèges. Par le biais de l’étude de la ville de Metz, nous avons mené une réflexion sur la nature de la ville d’Empire au tournant de l’Époque moderne. Cette étude nous a permis d’illustrer les moyens mis en place par la cité de Metz pour s’adapter aux transformations de l’Empire et d’en expliquer les motivations. Les magistrats de la cité durent s’entourer d’un personnel qualifié tant par sa formation et son expérience que par la maitrise de la langue allemande pour s’assurer de mener à bien leurs négociations diplomatiques, garantir leurs droits et privilèges et maintenir le dialogue politique avec l’empereur. En parallèle, le gouvernement urbain mit en place une activité de la traduction régulière des lettres impériales de l’allemand au français pour traiter la correspondance qui arrivait désormais essentiellement en langue allemande. Par l’étude des pratiques linguistiques, nous avons apporté des nuances au lien entre construction d’identité, langue et espace politique. En effet, à la fin du Moyen Âge, il ne saurait être question d’une équivalence entre unité étatique et unité linguistique dans l’espace du Saint Empire, une entité plutôt polycentrique et plurilingue. Cependant, la langue revêt bel et bien un rôle politique et identitaire. Par extension, cette thèse a également permis de porter une réflexion sur l’applicabilité des concepts de pays d’entredeux et de frontière linguistique pour la période médiévale.

description: Past research on the uptake of e-commerce is mostly US based, atheoretical and concerns Internet shopping, rather than encompassing the broader range of Internet financial transactions. 'Trust' has been implicated as an important predictor of consumer behaviour but its nature is unclear and data regarding its importance in comparison with other consumer, vendor, and website characteristics has been inconsistent. This investigation set out to assess the range of impediments to on-line transactions as perceived by end users in Australia, and the relative significance of the role of trust. The work was undertaken on behalf of a research consortium of public and private sector interests in Australia known as the Smart Internet Technology Cooperative Research Centre (SITCRC). The research was conducted in two stages. The pilot qualitative research stage was undertaken in Melbourne in March 2002 with focus groups where end users identified a range of impediments to Internet based financial transactions. The second stage involved a quantitative study in Melbourne in November/December 2002 of 2000 randomly selected Australian Internet. A telephone survey was used to assess a range of potential predictors of trust in on-line transaction behaviour based on the factors which emerged from the qualitative pilot study. This second study explored the role of perceptions of likelihood and seriousness of negative outcomes in Internet financial transaction behaviour. Results indicated that trust was the strongest predictor of use of the Internet for financial transactions. Demographic variables such as education, age and gender had complex relationships with on-line transaction behaviours. There are some clear pointers to major behavioural factors which have to be understood and addressed before the Internet becomes the major communications transactional platform.

description: This doctorate thesis focuses on investigating the parameter space involved in numerically modeling the bandgap engineering of a GaInP/InGaAs/Ge lattice matched multi-junction solar cell (MJSC) using InAs/InGaAs quantum dots (QDs) in the middle sub-cell. The simulation environment – TCAD Sentaurus – solves the semiconductor equations using finite element and finite difference methods throughout well-defined meshes in the device to simulate the optoelectronic behavior first for single junction solar cells and subsequently for MJSCs with and without quantum dots under concentrated illumination of up to 1000 suns’ equivalent intensity. The MJSC device models include appropriate quantum tunneling effects arising in the tunnel junctions which serve as transparent sub-cell interconnects. These tunneling models are calibrated to measurements of AlGaAs/GaAs and AlGaAs/AlGaAs tunnel junctions reaching tunneling peak current densities above 1000 A/cm^2. Self-assembled InAs/GaAs quantum dots (QDs) are treated as an effective medium through a description of appropriate generation and recombination processes. The former includes analytical expressions for the absorption coefficient that amalgamates the contributions from the quantum dot, the InAs wetting layer (WL) and the bulk states. The latter includes radiative and non-radiative lifetimes with carrier capture and escape considerations from the confinement potentials of the QDs. The simulated external quantum efficiency was calibrated to a commercial device from Cyrium Technologies Inc., and required 130 layers of the QD effective medium to match the contribution from the QD ground state. The current – voltage simulations under standard testing conditions (1 kW/cm^2, T=298 K) demonstrated an efficiency of 29.1%, an absolute drop of 1.5% over a control structure. Although a 5% relative increase in photocurrent was observed, a 5% relative drop in open circuit voltage and an absolute drop of 3.4% in fill factor resulted from integrating lower bandgap nanostructures with shorter minority carrier lifetimes. However, these results are considered a worst case scenario since maximum capture and minimum escape rates are assumed for the effective medium model. Decreasing the band offsets demonstrated an absolute boost in efficiency of 0.5% over a control structure, thus outlining the potential benefits of using nanostructures in bandgap engineering MJSCs.

L'approche structuraliste récente pose les schèmes mentaux des ontologies humaine comme facteur responsable possible. L'approche expériencielle pose l'éloignement entre l'être humain et la nature comme cause potentielle. L'approche proposant l'imposition d'une idéologie hautement technologique et moderne sur des savoirs locaux en est une autre. Ces trois approches sont utilisées pour analyser les données d'une recherche de terrain centrée sur des ensemencements de doré jaunes au réservoir Baskatong. Les caractéristiques d'un texte d'écologie politiques sous-tendent l'analyse. La compétitivité entre groupes humains ressort comme caractéristique incontournable d'une analyse de la situation, mieux représentée par la troisième approche et un texte en écologie politique. /// Abstract: Environmental degradation is explained through approaches varying according to anthropological theories. The recent structuralist approach poses different mental schemes of human ontologies as potentially responsible. The experiential approach poses a gap between humans and nature as a potential cause. Another approach proposes the imposition of a highly modernistic and technological ideology over local knowledges as explanation. These three approaches are used to analyze field data focussed on walleye stocking at the Baskatong reservoir. The characteristics of a political ecology text overarch the analysis. Results show competition between human groups as an unavoidable characteristic of the analysis, better represented in the third approach and political ecology.

description: Acute (~2 min) baroreceptor unloading was reported to modulate metaboreflex control of postexercise cutaneous blood flow, but not sweating. We examined whether sustained changes in baroreceptor loading status during prolonged postexercise recovery can alter the metaboreceptors’ influence on heat loss. Thirteen young males performed a 1-min isometric handgrip exercise (IHG) at 60% maximal voluntary contraction followed by 2-min of forearm ischemia (to activate metaboreceptors) before and 15, 30, 45 and 60-min after a 15-min intense treadmill running exercise (>90% maximal heart rate) in the heat (35°C). This procedure was repeated on three separate days with the application of lower-body positive (LBPP, +40 mmHg), negative (LBNP, -20 mmHg), or no pressure (Control) postexercise. Sweat rate (ventilated capsule; forearm, chest, upper back) and cutaneous vascular conductance (CVC; forearm, upper back) were measured. Relative to pre-IHG levels, sweating at all sites increased during IHG and remained elevated during ischemia at baseline and similarly at 30, 45, and 60-min postexercise (site average sweat rate increase during ischemia: Control, 0.13±0.02; LBPP, 0.12±0.02; LBNP, 0.15±0.02 mg·min-1·cm-2; all P<0.01), but not at 15-min (all P>0.10). LBPP and LBNP application did not modulate the pattern of sweating to IHG and ischemia (all P>0.05). At 15-min postexercise, forearm CVC was reduced from pre-IHG levels during both IHG and ischemia under LBNP only (ischemia: 3.9±0.8 %CVCmax; P<0.02). Therefore, we show metaboreceptors modulate postexercise sweating in the mid-to-late stages (30-60 min) of recovery, independent of baroreceptor loading status and similarly between skin sites. In contrast, metaboreflex modulation of forearm but not upper back CVC occurs only in the early stages of recovery (15 min) and depends upon baroreceptor unloading.

description: With the launch of foundation models like DeepSeek, Manus AI, and Llama 4, it has become evident that large language models (LLMs) are no longer the sole defining factor in generative AI. As many now operate at comparable levels of capability, the real race is not about having the biggest model but optimizing the surrounding ecosystem, including data quality and management, computational efficiency, latency, and evaluation frameworks. This review article delves into these critical differentiators that ensure modern AI services are efficient and profitable.

How do I marginalise thee? Let me count the ways: discourses of marginalisation in the student-supervisor relationship
Creators: name: Barron, Deirdre

description: The theory and practice of postgraduate supervision constructs academic supervisors as the custodians of ‘friendship’ in the supervisory relationship. This construction also demands compatibility between students and supervisors as an essential to a successful candidature. This paper does not dispute that a co-operative relationship between student and supervisor can be a bonus in the supervisory relationship. However, we argue that ‘friendship’ as a discourse has the potential to marginalize both the supervisor and the student as it constructs and is constructed by each to disempower the other. This paper examines the discourses and the technologies of friendship in the supervisory relationship, and argues that a more collegial and professional discourse opens new possibilities for different practices in postgraduate pedagogies.

description: Continuous operation presents multiple advantages over batch chemistry, yet its usage in the fine chemical and pharmaceutical industry remains limited due to its complexity. A holistic tool-box approach for process development is presented to facilitate technology transfer. Reaction kinetics and reacting phases were taken into consideration for the selection of the most appropriate reactor module and operating conditions. A micro-reactor was then more specifically developed for fast liquid-liquid reactions. The effect of physical properties was investigated in a serpentine micro-reactor using a reactive liquid-liquid extraction and different organic solvents (n-butanol, n-hexanol, MTBE and toluene). The generated droplets yielded a specific interfacial area of 10^4-10^5 m2/m3, compared to ~10^2 m2/m3 with conventional equipment. Two models were developed to predict the mass transfer rates for other reactive systems. Further, the effect of geometry was investigated with five different micro-reactors using either curvature-based or obstacle-based micro-mixers. Curvature-based micro-mixers promoted the undesired parallel flow pattern due to stabilizing centrifugal forces, while obstacle-based micro-mixers avoided it. A scale-up approach was finally proposed on a micro-reactor using an optimized micro-mixer. The mass transfer coefficients in a small-scale (1.5-15 mL/min) and a large-scale (12.5-125 mL/min) systems were compared and demonstrated its validity. The obtained results allowed the prediction, the optimization, and the scaling of performance for liquid-liquid systems in the context of process development from molecular discovery to clinical trials and pilot scale production.
North American Professional Sport: Exploring Competition Time and its Effect on Valuation, Revenue and Profitability

description: This thesis examines if there is a relationship between competition time and team valuation, revenue and profitability in North American professional sport. The leagues examined were the major four in North America and include the National Basketball Association, Major League Baseball, the National Hockey League and the National Football League. Using the Balanced Scorecard (BSC) as a guide, appropriate literature of the four BSC categories was reviewed. The four categories of the BSC include Financial, Customer, Internal Business Processes and Learning and Growth. Conceptual models for team valuation, revenue and profitability were constructed using the BSC as a framework. In order to construct the three conceptual models 51 professional sport research variables were identified as useful to this framework. The data was collected over a ten-year period for the seasons 2003/2004-2012/2013. A series of statistical analyses were examined with regression analyses revealed three distinct models for the three dependent variables. It was found that competition time has a significant impact on all three dependent variables. The results from this study will help league executives in creating new strategies for revenue growth and other financial gains. Future research will work towards creating more competition time variables that will aid in determining the proper amount of competition time that needs to be played by each league to maximize league finances.

description: While many African governments have made legislative changes to the formal economic institution of land law in order to strengthen land tenure security, very few have seen these changes take hold (Bruce & Knox, 2009). This thesis demonstrates that Uganda is no exception. In exploring the interactions between the formal, informal, political, economic and social institutions which influence land tenure behaviour in Uganda, and how decentralization impacts this institutional structure, this thesis offers a first step in understanding how state-led land reforms can be undercut at the local level, causing unintended outcomes. From reinforcing the legitimacy of informal customary tenure systems to fostering inter-ethnic competition, the District of Kayunga demonstrates how Uganda’s 1998 Land Reform has created unexpected impacts that continue to impede its implementation. It also offers ideas on how failed institutional adaptations may impact local perceptions of land tenure security. This thesis also investigates and pushes the boundaries of New Institutional Economic (NIE) theory. It explores how decentralization within a formal economic institution can influence informal social and political institutions to create complex and ever evolving incentive structures. It also examines the role of organizations and individuals in an effort to understand the intersection between these two categories of actors and the institutional structure. Fluid interactions whereby organizations and individuals are incentivized by institutions, but also resist and adapt to institutional change, demonstrate the added complexity of organization-institution interdependency within the NIE framework.

description: This research was a collaborative project funded by Visy Research and Development Pty. Ltd. and undertaken between Visy Packaging Systems Division (PSD) and the Industrial Research Institute Swinburne (IRIS). The project commenced in July 2000 and was completed in July 2002. The primary objective of the project involved an investigation of how to increase the flexibility of corrugated fibreboard (CFB) tray forming equipment by developing a flexible (size changing) mandrel and well system which folds the trays from a flat blank. This type of equipment is produced by Visy PSD and installed at customer sites. This objective was achieved, and a working, innovative prototype was developed and manually tested. This paper provides a background introduction to the corrugated fibreboard folding machine history with particular regard to flexible mandrels. The industrial implications of the research and development program are overviewed and an introduction to the CFB tray folding process is provided. The size change requirements are defined and the design and development process used in guiding the research and development program is outlined. The prototype was designed, built and subjected to manual testing and was adopted by Visy PSD and was being incorporated into a complete machine for customer production use.
Gravity Concentration in Artisanal Gold Mining

description: Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore. This latter method has been causing large losses of mercury to the environment and the most relevant world’s mercury pollution. For years, international agencies and researchers have been promoting gravity concentration methods as a way to eventually avoid the use of mercury or to reduce the mass of material to be amalgamated. This article reviews typical gravity concentration methods used by artisanal miners in developing countries, based on numerous field trips of the authors to more than 35 countries where artisanal gold mining is common.

description: This thesis investigates the building of a textual tracing language that operates at the model level to allow trace specification of textually modeled UML constructs. Current tracing approaches focus on manually injecting tracepoints into targeted systems at the source code level. Such approaches are useful in code-centric development styles where the majority of the code is handwritten. However, in the case of Model Driven Development (MDD), where models are utilized to generate some or all of the code, current tracing technology results in low level trace specification and generation of execution traces that are not aware of or linked to the originating model-level constructs. Dynamic analysis hence becomes harder for a modeler adopting an MDD approach. This field, which we call model-oriented tracing, is currently immature, with little pre-existing research. In this thesis, we present a textual model-level tracing language, implemented as part of Umple, that overcomes some of the limitations of existing tracing methods. The language facilitates model-level tracing, in a fashion very similar to code tracing. The language, which we call MOTL (Model-Oriented Tracing Language) allows tracing of UML associations, attributes and state machines. Constraints can be imposed to limit the scope of tracing. As a result of this work, modelers will gain the ability to specify traces of UML constructs at the model level without the need to modify the generated code, and then generate execution traces when the generated system is run. The resulting trace links back to the model constructs. Modelers can choose from among several tracing technologies including basic file or console output, Java logging framework, Log4J and LTTng. This thesis defines the language syntactically and semantically. Model-Driven Development (MDD) and Test-Driven Development (TDD) were followed to implement the language architecture to ensure high quality code generation. MOTL was used in the development in two of Umple subprojects. An empirical evaluation was conducted to evaluate the language’s usability.
Étude de composés binaires denses sous haute pression

description: Les études de mélanges binaires sous conditions extrêmes ont mené à la découverte de solides appelés composés van der Waals. La découverte d’un composé van der Waals dans un mélange de deux gaz nobles par Loubeyre et al. (1993) permet de supposer que différentes combinaisons de gaz nobles formeront, aux conditions pression-température-concentration appropriées, de tels solides. Des échantillons de gaz nobles (néon + argon) et (hélium + argon) furent étudiés sous hautes pressions par diffraction de rayons X issus du rayonnement synchrotron dans le but de former et caractériser un composé inédit. Une faible miscibilité des espèces étudiées est observée via la présence de démixtions et de solutions solides dans les échantillons. Parallèlement, une étude du composé binaire (azote + méthane) a été poursuivie par l’affinement des positions moléculaires d’un composé van der Waals connu pour ce système. Des solutions potentielles pour la structure cristalline sont proposées et discutées.
Critical Role of c-IAP-2 in Mediating Mechanisms of Resistance to HIV-Vpr-induced Apoptosis in Human Monocytic Cells

description: Monocytic cells survive HIV replication and consequent cytopathic effects because of their decreased sensitivity to HIV-induced apoptosis. However, the mechanism underlying this resistance to apoptosis remains poorly understood. I hypothesized that exposure to microbial products, translocated from the gut, may confer anti-apoptotic properties in human monocytic cells through interaction with their corresponding Toll-like receptors (TLRs). Using HIV-Vpr(52-96) peptide as a model apoptosis-inducing agent, I demonstrated that unlike monocyte-derived macrophages, undifferentiated primary human monocytes and pro-monocytic THP-1 cells are highly susceptible to Vpr(52-96)-induced apoptosis. Interestingly, monocytes and THP-1 cells stimulated with TLR-9 agonists, CpG and E.coli DNA, induced almost complete resistance to Vpr(52-96)-induced apoptosis albiet via a TLR-9 independent signaling pathway. Moreover, CpG and E.coli DNA selectively induced the anti- apoptotic Inhibitor of Apoptosis Protein-2 (c-IAP-2) and inhibition of the c-IAP-2 gene by either specific siRNAs or synthetic second mitochondrial activator of caspases (Smac) mimetic reversed CpG-induced resistance against Vpr(52-96)-mediated apoptosis. I demonstrated that c-IAP-2 was regulated by the c-Jun N terminal kinase (JNK) and the calcium signaling pathway in particular the calmodulin-dependent protein kinase-II (CaMK-II). Furthermore, inhibition of JNK and the calcium signaling including CaMK-II by either pharmacological inhibitors or their specific siRNAs reversed CpG-induced protection against Vpr(52-96)-mediated apoptosis. I also showed that CpG-induced JNK phosphorylation through activation of calcium signaling pathway.

description: We combine the results of a large HST study of rich LMC clusters with state of the art N-body simulations. We summarise recent highlights from our project: the estimation of age spreads in young LMC clusters, the measurement of the binary fraction of NGC1818, and the determination of deep cluster luminosity functions (LF). We also present preliminary results from an investigation of the core radius versus age relation evident among LMC clusters.
