Résumé :

This study examines how students in Finland (16-18 years of age) constructed meaning and knowledge in a collaborative online reading situation. Student pairs ( n = 19) were asked to write a joint essay on a controversial issue. First, the pairs discussed the topic freely to activate their prior knowledge. Next, they gathered source material on the Internet. Finally, they composed a joint essay. The data were collected using an interaction approach to verbal protocol data, along with video screen captures. In the analysis, three units were employed: episodes ( n = 562) for describing online reading practices; utterances ( n = 944) for identifying collaborative reading strategies; and collaborative reading patterns ( n = 435) for clarifying how the student pairs constructed meaning and knowledge. Collaborative reading patterns were categorized according to a four-part model. A hierarchical cluster analysis was conducted to identify students’ collaborative reading profiles. Five collaborative reading profiles emerged: co-constructers (two pairs), collaborators (two pairs), blenders (six pairs), individually oriented readers (four pairs), and silent readers (five pairs). Overall, it appeared that some students were capable of working in pairs, whereas others had a stronger preference for working alone. Collaborative profiles might offer teachers both an evaluative and an instructional tool to support collaborative interaction in their classrooms.

Résumé :

AbstractThe well known Wiener-Kuratowski explicit definition of the ordered pair, which sets (x,y) = {{x}, {x,y}}, works well in many set theories but fails for those with classes which cannot be members of singletons. With the aid of the Axiom of Foundation, we propose a recursive definition of ordered pair which addresses this shortcoming and also naturally generalizes to ordered tuples of greater length. There are many advantages to the new definition, for it allows for uniform definitions working equally well in a wide range of models for set theories. In ZFC and closely related theories, the rank of an ordered pair of two infinite sets under the new definition turns out to be equal to the maximum of the ranks of the sets.

Résumé :

Resorption refrigeration system, a novel type of chemisorption technique, employs two or more inorganic salts as sorbent reactants, which co-operate as working pair. The working conditions and some evaluation indicators of the resorption system with different working pairs in previous studies are collected and summarized in this work. The performance of the reactant salts is compared, and further effort direction of the selection of working pairs is also analyzed.

Résumé :

Innovation is a collaborative act. Thus, a lot of attention has been paid to teamwork as the prevalent approach for innovation in companies. However, teams also present limits, due to conflicts and compromises when converging. This study, which focuses on the development of innovative directions, explores the nature of collaboration by looking at the purest unit of collaboration: the pair. We isolate the case of pair collaboration and investigate, through empirical investigations, the sensemaking process people accomplish and how it is affected by those tensions that affect teams when innovating. We observe how innovation unfolds when people move from creating individually, in pair and finally in team. Findings suggest that the pair creates an intimate environment where innovative thinking, alignment and engagement flourish and that it is a good intermediate step towards teamwork. This paper acknowledges an underestimated dynamic of innovation, pair collaboration, which has real potential to address one of organisations’ most problematic challenges: people engagement and convergence towards an innovative direction.

Texte intégral

Résumé :

This thesis was aimed to analyse the feasibility and the performance of ionic liquids as an absorbent for ammonia refrigerant in absorption refrigeration systems. Ionic liquids, novel and tailor-made absorbents, can be used with ammonia as working pairs for absorption refrigeration cycles and give some advantages such as elimination of the rectification process in ammonia/water systems. The performances of several ammonia/ionic liquid mixtures working pair available in the literature were then theoretically studied and analysed for absorption refrigeration applications using selected NRTL model. In addition, new selected ammonia/ionic liquid mixtures working pair for absorption refrigeration applications were also theoretically studied and analysed. The results show that the coefficient of performance (COP) of the absorption systems working with ammonia/ionic liquid working fluids were about similar when compared with ammonia/LiNO3 at same cooling capacity and operation conditions. Among all of selected ammonia/ionic liquid working fluids studied in this thesis, only [N1113][NTf2] presented higher COP that that of ammonia/LiNO3 at certain operation conditions. The COP of the systems with other ionic liquids as absorbents follows an order of [EtOHmim][BF4] > [N111(2OH)][NTf2] > [EtOHmim][NTf2] at all operation conditions. Finally it can be concluded that the ionic liquid has a great potential to be an alternative absorbent for ammonia refrigerant. The ammonia/ionic liquid working fluid can provide competitive performance in comparison with conventional absorbent for ammonia refrigerant. However, some drawbacks were still remains to be solved such as relatively low solubility of ammonia into ionic liquids which affects to the solution circulation mass flow ratio and relatively high viscosity of ionic liquid in comparison with other conventional absorbent which may affects to the performance of absorber and solution pump.

Résumé :

According to former brain surgeon, Nils Simonson, Swedish schools are wasting their students’ time by using teaching methods that lead to poor memorization, namely reading and listening as separate activities. He instead suggests that the students use methods that lead to better memorization. The study described in this rendering focuses on two of Simonson’s suggestions – discussion and peer teaching. This work accounts for a study, in which Swedish 8 thgrade English students were working in asymmetrical pairs, i.e. pairs composed by students on different levels of achievement. The study was aimed at finding an answer to the thesis question of whether working in asymmetrical pairs led to a larger or smaller improvement, on a final grammar test, than the improvement of the rest of the students in the class, who were working individually, and thus formed a control group for the study. The result was that the students in three out of four asymmetrical pairs improved their results more than the control group. Since one of the students in the fourth asymmetrical pair had been absent, they had only been working together during half the period of the study. This probably explains why their improvement was only on the same level as the improvement of the students in the control group. The answer to the thesis question is therefore that working in asymmetrical pairs led to better results on the final grammar test, than working individually. If the results of the participating students are divided into different groups, we also find that the students with the lowest results on the initial grammar test were those who improved their results the most, which could possibly be explained by a better room for improvement. Due to the short time range of the study, it was limited to one class, and the generalizability of the study is hence very low. However, it could potentially serve as a pilot study for larger research projects. My main idea of future research is thus to expand the study to a larger number of students. It would also be interesting to incorporate students on all levels of achievement into a similar research project. This work incorporates predominant teaching science theory, such as socio-cultural theories, and influential second language acquisition theory, such as the input hypothesis, the output hypothesis and focus on form instruction.

Résumé :

In New Zealand, approximately 10% of births are considered premature, that is less than 37 weeks gestation. With advances in medical technology, young infants are surviving gestation periods as few as 23 weeks. It is expected that many of these severely premature infants will demonstrate some problem in their academic, or cognitive function including language functioning. It is agreed that children who are born severely premature often present with language problems, the nature of the difficulties are not clear. Research examining language abilities that involve cognitive functions such as inference generation have demonstrated that children born prematurely exhibit difficulties with phonologic short-term memory and executive function. Language tasks such as inference understanding require children to integrate real-world knowledge with the linguistic information to generate and produce language that is more complex. The aim of this study was to discover if the language of children born severely premature differs from that of language-age matched peers. This study examined high-level language abilities of school-age children born severely prematurely, specifically, language tasks that involved executive functions including working memory, story inferencing, and recognising absurdities. Six children who were born less than 28 weeks gestation participated in this study. Their results on the above measures were compared to a language-aged matched comparison group, determined by performance on a standardised test. It was hypothesised that the children born severely premature would not differ from their language-age matched peers on measures of general language ability but differences would exist on measures of language processing and inferencing. The findings overall showed little difference between the preterm group and their language-age matched peers on measures except for the measure of chronological age. Although no group difference was found for the measure of working memory, a larger variance on this measure was observed in the preterm group.

Texte intégral

Résumé :

This work presents the design of a double effect thermochemical heat pump based on the calcium chloride-ammonia and magnesium chloride-ammonia working pairs. The work began with a comprehensive theoretical and literature review of the similar systems which exist in the literature. Once the literature review was done, a large temperature jump experimental rig was built in order to be able to determine the behaviour of the relevant working pairs. Even though the focus of the work is thermochemical reactions, the activated carbon-ammonia pair was first used to validate the large temperature jump rig. The reason for this is that the activated carbon-ammonia pair is better understood compare to the thermochemical reactions. The experiments on the activated carbon- ammonia pair yielded some useful results. The results obtained show that two heat transfer properties (thermal conductivity, k and heat transfer coefficient, h) with physical meaning can be extracted from large temperature jump data. Furthermore, the change in thermal conductivity with the packing density of the adsorbent was investigated. The general trend was one of increasing thermal conductivity as the packing density was increased, the thermal conductivity increased from 0.2Wm‾¹K‾¹ to 0.4Wm‾¹K‾¹ as the packing density was increased from 530kgm‾³ to 705kgm‾³. When the calcium chloride-ammonia and magnesium chloride-ammonia working pairs were investigated in the large temperature jump setup, the kinetic parameters for each respective reaction were obtained. This enabled the development of a dynamic model of a representative thermochemical heat pump based on the aforementioned working pairs. The dynamic model helped to investigate the performance of the heat pump under various operating conditions. The coefficient of performance (COP) and the specific heating power ranged from 1.21 to 1.40 and 40W/litre to 400W/litre respectively depending on the operating conditions.

Résumé :

This study examined the idea that each mathematical operation (addition, subtraction, multiplication and division) is mainly linked to one of the components of working memory as proposed by Baddeley. The phonological loop, visual-spatial sketchpad and central executive have been studied using a dual-task methodology with 7 different secondary tasks. 35 undergraduate and graduate students were timed in their response time for mental calculation and error rates were calculated. Results show clear differences of operations and of number pairs. Interaction between conditions and operations was just approaching significance. Results did not give support to the idea that operations can be linked to a certain working memory component. Several factors, such as language, problem size, lack for detail in the working memory model, difficulty of the secondary tasks, and internal validity problems are discussed with regard to the results and mental arithmetic.

Résumé :

Notre thèse vise à étudier expérimentalement les effets de différents types de situations conversationnelles de co-résolution de problèmes sur les activités cognitives d'élèves de S.E.G.P.A. en grande difficulté scolaire (Section Enseignement Général Professionnel Adapté). Elle s'inscrit dans une approche socio-constructiviste du fonctionnement et du développement du système cognitif et prend appui sur la thèse vygotskienne postulant l'origine sociale des processus mentaux supérieurs et sur les travaux s'en réclamant, attestant que les interactions et les significations de la tâche et/ou du contexte favorisent le fonctionnement et le développement des activités mentales supérieures. Trois expérimentations ont été réalisées, mettant les participants dans des situations de résolution de problèmes selon plusieurs types de contextes interactifs : face à face, au téléphone, en vidéoconférence, via une messagerie instantanée (MSN), et en individuel. Les résultats mettent en évidence l'intérêt du travail en dyade et font apparaître des différences quant aux performances, au temps de résolution, au nombre et la nature des actes de communication lors de la co-résolution. L'analyse des échanges au moyen de l'analyse interlocutoire valide la thèse selon laquelle les deux fonctions (communicative et significative) des médiations sémiotiques s'accomplissent en même temps lors des transactions conversationnelles pour construire l'intersubjectivité, et sont appropriées par les partenaires pour (ré)organiser les systèmes cognitifs individuels
Our thesis aims at study experimentally the effects of various types of conversational situations of co-resolution of problems on cognitive activities upon teenagers attending the “college” and in great school difficulty. It falls under a socio-constructivist approach of functioning and development of the cognitive system, and takes support on the vygotskian thesis postulating a social origin of higher mental processes and on researches supporting it, stating that the interactions and the significance of the task and/or the context can promote the functioning and development of higher mental activities. Three experiments were organized. Participants had to solve problems according to several types of interactive contexts: face to face, on the telephone, in videoconferencing, via instant messaging (MSN), and individually. The results highlight the interest of working in dyad and reveal differences as for the performance, the time of resolution of the task, the number and the nature of communication acts carried out during the co-resolution. The interlocutory analysis of the exchanges validates the thesis that the two functions (communicative and significant) of the semiotic mediations are achieved simultaneously within transactions to build the intersubjectivity, and are appropriate by partners to (re)organize their own cognitive system. The differences observed can also allow to give some guidelines of work on the development of devices of teaching and learning with “college” students with learning difficulties or not

Résumé :

This thesis examines the role of women in the Parisian economy in the late thirteenth century. The Livre des metiers of Etienne Boileau offers normative provisions regarding societal structures that permitted but restricted the participation of women, while the tax rolls commonly known as the roles de la taille de Philippe le Bel furnish numbers which show their actual participation. While these sources are well known, they have not heretofore been rigorously examined. Conclusions about women based on them have been amorphous. Married women are nearly invisible in these records, but unmarried women and widows headed 13.6% of Parisian workshops. Women monopolized the Parisian silk industry. About one-third of Parisian women in the late thirteenth century worked in jobs traditionally considered "women's work," including the preparation of food and clothing, peddling food on the street, and providing personal services. The other two-thirds did nearly every kind of work that men did. A "putting out" system was well in place in Paris at this time. Women classified as chambrieres or ouvrieres worked at home, spinning and weaving raw materials provided by an entrepreneur and selling back to the entrepreneur the finished product. Working at home allowed a woman to combine household duties with production for the marketplace. Girls usually learned a trade by working alongside their parents. Formal apprenticeships were less common for girls than for boys. While women could and did participate in nearly every trade, their numbers were concentrated in the lowest-paid metiers. The few women who practiced trades dominated by men were much more successful financially.

Résumé :

Este estudio investiga la conductividad térmica de fluidos de trabajo para ciclos de refrigeración por absorción activados por energía solar o calor residual. Una mezcla prometedora es el NH3+LiNO3. Sin embargo, el conocimiento de las propiedades termofísicastales como la conductividad térmica,son necesarias para un diseño adecuado de estos sistemas. Por lo tanto, en este trabajo se ha medido la conductividad térmica de esta mezcla con una fracción másica de amoníaco ente el 0.3-0.6 y temperaturas de entre 303.15 y 353.15 K. Los resultados obtenidos muestran valores bajos de conductividad térmica, y se sabe que la baja conductividad es una de las limitaciones principales en el desarrollo de los fluidos de transferencia de calor. Para superar esta limitación, se propuso la adición de agua o nanotubos de carbono a la mezcla binaria (NH3+LiNO3). Se ha visto que la adición de un tercer componente indica una mejora en la conductividad térmica en ambos casos. Las medidas de conductividad térmica se llevaron a cabo mediante el método transitorio de hilo caliente y dos equipos experimentales diferentes fueron diseñados y construidos en este trabajo. La incertidumbre en las mediciones se estima en menos del0.025 W•m-1•K-1. Por último, los datos experimentales se correlacionaron con un modelo matemático basado en el “local composition concept” y teniendo en cuenta el efecto de los electrolitos.
This study investigates the thermal conductivity of working fluids for absorption refrigeration cycles activated by solar energy or waste heat. A promising mixture is NH3+LiNO3. However, accurate thermophysical properties such as thermal conductivity are needed for adequate design, analysis and evaluation of such systems. Therefore, this property has been measured with ammonia mass fraction range from 0.3 to 0.6 and temperatures between 303.15 and 353.15 K. Results show low values in thermal conductivity, and it is known that low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in these systems. To overcome this limitation, the addition of water or carbon nanotubes to the binary mixture (NH3+LiNO3)was proposed. It has been seen that the addition of a third component indicates an enhancement in the effective thermal conductivity in both cases. Thermal conductivity measurements were carried on with the transient hot wire technique and two different devices were designed and built in this work. Uncertainty in the measurements was estimated to be less than 0.025 W•m-1•K-1. Finally, the experimental data was fitted with a comprehensive model based on the local composition concept and the effect of electrolytes.

Résumé :

AbstractThis study focuses on sharing, both in equal parts (groups) or unequal parts. Children at age five attending preschool, are faced with two different tasks working in pairs. The analysis focus on the mathematical properties in the reasoning, or when mathematical arguments were replaced with an ethical reasoning. When performing division, different strategies were used, and the norm of fair share was often expressed. It was easier for the children to allocate resources when the dividend was larger than the divisor, and when dealing with a fraction, the cardinality of the number of parts appeared to be a prominent property compared to property ‘equal size’ of the parts. There were also indications of ethical reasoning where the child used different claims to convince their peer. There was a tension between the norm of equal sharing and solutions with unequal parts. One implication is that if wanting to challenge children’s mathematical reasoning in a division task, it could be fruitful to look at fractions instead of repeating tasks where the dividend is larger than the divisor.

Résumé :

This study provides the first statistically significant evidence that the mechanisms of how pair bonds are created or maintained differ between gibbon taxa. We examine the pair bond in captive pairs of three genera of gibbons (Hylobatidae): siamangs (Symphalangus, N = 17 pairs), crested gibbons (Nomascus, N = 7 pairs), and pileated gibbons (Hylobates pileatus, N = 9 pairs). In the first part of this study, we determine three generally-accepted indicators of pair-bond strength (mutual grooming, behavioral synchronization and partner distance). A pairwise comparison of our samples reveals a difference in relative partner distances between siamangs and pileated gibbons, suggesting that siamangs may have a stronger pair bond than pileated gibbons. No difference among the three taxa was found in other variables believed to indicate pair bond strength. In the second part we examine the amount of partner-directed grooming in each sex. In siamangs, males invest significantly more into pair bonds than females, whereas the opposite is true in crested and pileated gibbons. Our results for siamangs correspond to predictions derived from the ‘mate-defense hypothesis’ for the evolution of pair bonds, whereas our results for crested gibbons and pileated gibbons correspond to predictions derived from the ‘male-services hypothesis’.

Résumé :

In an optical network, given a pair of source and destination nodes, some algorithm can be used to find shortest pairs of edge-disjoint paths to be used as working and backup paths. The Suurballe and Tarjan's algorithm is a solution, but it can found different shortest pairs of pathways interconnecting the same pair of source and destination nodes. In this paper, two versions of the Suurballe and Tarjan's algorithm is proposed to deal with that diversity. For each node pair of a given network topology, these versions find the most balanced shortest pair of working and backup paths and the least balanced one. Both algorithms are tested and analyzed in a set of 40 2-edge-connected topologies of real-world optical telecommunication networks. A difference of up to 29% was found between the two strategies.

Résumé :

The silica gel-water working pair has been commonly used for commercial adsorption chillers due to the environmental benign refrigerant and low desorption temperature (less than 85°C). However, the application has been constrained due to the vacuum working condition and Ice point. This motivates researchers to investigate alternative working pairs. The silica gel-based adsorbents - ammonia working pairs have been found to be the most promising alternative. The isotherms and heats of adsorption of the working pair are essential to be investigated for designing the adsorption reactor and predicting the chiller performance. A novel sensor-gas calorimeter has been used to simultaneously measure the adsorption isotherm and heats of adsorption. The experimental results for adsorption of ammonia on the pure silica gel and silica gel treated with different weight percentage of calcium chlorine are presented.

Résumé :

This study deals with the performance analysis of single- and multi-stage adsorption cooling cycles working at partial vacuum and pressurized conditions for cooling applications. Four adsorbent-refrigerant pairs namely activated carbon fiber-ethanol, silica gel-water, Maxsorb II-R134a and Fluka-R134a pairs have been investigated. The former two pairs are deemed to be suitable for adsorption cycles working at pressures ranging from 1 to 11 kPa while the latter two are suitable for those working at above atmospheric pressure conditions typically between about 0.3 and 0.8 MPa. Invoking the adsorption isotherms of the assorted pairs, the pressure-temperature-concentration (P-T-W) diagrams have been presented. Pertaining a thermodynamic framework, the performance of both single- and multi-stage cycles in terms of specific cooling effect (SCE) and coefficient of performance (COP) has also been studied. Theoretical results show that the former two pairs i.e., the adsorption cycles working at partial vacuum pressures are suitable for surface cooling while latter two are suitable for micro cooling applications. Moreover, the multi-stage adsorption cycles can be operational at a heat source temperature below about 55°C, a region that could not be reached by any conventional adsorption cycle.

Résumé :

University support services are often underutilised by ethnic minority male students. This research aimed to identify the perceptions of ethnic minority male students around using university mental health support services, including the barriers and facilitators to utilisation. The project used Listening Rooms for data collection, whereby participants pair up and undertake a recorded conversation based around talking points pertaining to the project. Fourteen pairs (n=28) participated in conversations. A round table analysis of the data took place, followed by further thematic analysis on the transcripts using Nvivo. Participants overall appeared to be positive about and grateful for, the existence of a mental health support service, despite a mixed level of awareness of its existence and differing conceptualizations of what mental health means. Barriers to service utilisation could be split into institutional and sociocultural. Institutional barriers included a perceived lack of cultural and ethnic representation amongst practitioners, as well as bureaucratic factors such as access difficulties, whereas sociocultural barriers pertained to cultural taboos and fear of judgement. As university intakes become ever more diverse, university support services must adapt to meet the needs of their populations. Findings support the need for a more representative staffing of services which would engender confidence in ethnic minority male students. Working to further raise awareness levels of the service as well as explaining how, when and why one might access the service would also be beneficial to those who do seek support.

Résumé :

This report is one of a series of reports documenting the methods and findings of a multi-year, multi-disciplinary project coordinated by the Pacific Earthquake Engineering Research Center (PEER) and funded by the California Earthquake Authority (CEA). The overall project is titled “Quantifying the Performance of Retrofit of Cripple Walls and Sill Anchorage in Single-Family Wood-Frame Buildings,” henceforth referred to as the “PEER–CEA Project.” The overall objective of the PEER–CEA Project is to provide scientifically based information (e.g., testing, analysis, and resulting loss models) that measure and assess the effectiveness of seismic retrofit to reduce the risk of damage and associated losses (repair costs) of wood-frame houses with cripple wall and sill anchorage deficiencies as well as retrofitted conditions that address those deficiencies. Tasks that support and inform the loss-modeling effort are: (1) collecting and summarizing existing information and results of previous research on the performance of wood-frame houses; (2) identifying construction features to characterize alternative variants of wood-frame houses; (3) characterizing earthquake hazard and ground motions at representative sites in California; (4) developing cyclic loading protocols and conducting laboratory tests of cripple wall panels, wood-frame wall subassemblies, and sill anchorages to measure and document their response (strength and stiffness) under cyclic loading; and (5) the computer modeling, simulations, and the development of loss models as informed by a workshop with claims adjustors. This report is a product of Working Group 3 (WG3), Task 3.1: Selecting and Scaling Ground-motion records. The objective of Task 3.1 is to provide suites of ground motions to be used by other working groups (WGs), especially Working Group 5: Analytical Modeling (WG5) for Simulation Studies. The ground motions used in the numerical simulations are intended to represent seismic hazard at the building site. The seismic hazard is dependent on the location of the site relative to seismic sources, the characteristics of the seismic sources in the region and the local soil conditions at the site. To achieve a proper representation of hazard across the State of California, ten sites were selected, and a site-specific probabilistic seismic hazard analysis (PSHA) was performed at each of these sites for both a soft soil (Vs30 = 270 m/sec) and a stiff soil (Vs30=760 m/sec). The PSHA used the UCERF3 seismic source model, which represents the latest seismic source model adopted by the USGS [2013] and NGA-West2 ground-motion models. The PSHA was carried out for structural periods ranging from 0.01 to 10 sec. At each site and soil class, the results from the PSHA—hazard curves, hazard deaggregation, and uniform-hazard spectra (UHS)—were extracted for a series of ten return periods, prescribed by WG5 and WG6, ranging from 15.5–2500 years. For each case (site, soil class, and return period), the UHS was used as the target spectrum for selection and modification of a suite of ground motions. Additionally, another set of target spectra based on “Conditional Spectra” (CS), which are more realistic than UHS, was developed [Baker and Lee 2018]. The Conditional Spectra are defined by the median (Conditional Mean Spectrum) and a period-dependent variance. A suite of at least 40 record pairs (horizontal) were selected and modified for each return period and target-spectrum type. Thus, for each ground-motion suite, 40 or more record pairs were selected using the deaggregation of the hazard, resulting in more than 200 record pairs per target-spectrum type at each site. The suites contained more than 40 records in case some were rejected by the modelers due to secondary characteristics; however, none were rejected, and the complete set was used. For the case of UHS as the target spectrum, the selected motions were modified (scaled) such that the average of the median spectrum (RotD50) [Boore 2010] of the ground-motion pairs follow the target spectrum closely within the period range of interest to the analysts. In communications with WG5 researchers, for ground-motion (time histories, or time series) selection and modification, a period range between 0.01–2.0 sec was selected for this specific application for the project. The duration metrics and pulse characteristics of the records were also used in the final selection of ground motions. The damping ratio for the PSHA and ground-motion target spectra was set to 5%, which is standard practice in engineering applications. For the cases where the CS was used as the target spectrum, the ground-motion suites were selected and scaled using a modified version of the conditional spectrum ground-motion selection tool (CS-GMS tool) developed by Baker and Lee [2018]. This tool selects and scales a suite of ground motions to meet both the median and the user-defined variability. This variability is defined by the relationship developed by Baker and Jayaram [2008]. The computation of CS requires a structural period for the conditional model. In collaboration with WG5 researchers, a conditioning period of 0.25 sec was selected as a representative of the fundamental mode of vibration of the buildings of interest in this study. Working Group 5 carried out a sensitivity analysis of using other conditioning periods, and the results and discussion of selection of conditioning period are reported in Section 4 of the WG5 PEER report entitled Technical Background Report for Structural Analysis and Performance Assessment. The WG3.1 report presents a summary of the selected sites, the seismic-source characterization model, and the ground-motion characterization model used in the PSHA, followed by selection and modification of suites of ground motions. The Record Sequence Number (RSN) and the associated scale factors are tabulated in the Appendices of this report, and the actual time-series files can be downloaded from the PEER Ground-motion database Portal (https://ngawest2.berkeley.edu/)(link is external).

Résumé :

A partitioning inter-well tracer test (PITT) determines the residual (or even remaining) oil saturation (SOR) in the flooded region between well-pairs. This type of tracer test can be used to identify improved oil recovery (IOR) targets, evaluate IOR projects, evaluate enhanced oil recovery (EOR) methods, and improve reservoir description for efficient hydrocarbon production. Thus, the main objective of the work with inter-well oil/water partitioning tracers developed within the framework of the IOR Centre is to provide tools and methodologies to improve reservoir description for efficient management of resources. The present report aims to provide insight to its users on the deployment of tracer technology in the inter- well region of water-flooded reservoirs to determine SOR. In turn, this parameter can be used as basis to evaluate the efficiency of several oil-production related operations. It will explain workflows, expertise, and tools needed as well as the importance of the information obtained, and methods to obtain it. This report is directed towards operators, primarily to reservoir engineers and reservoir managers, and service companies, particularly those already engaged on the deployment of tracer technology or those who aim to begin this activity. R&D personnel working in both operators and service companies may also benefit from the contents of the present report.

Texte intégral

Résumé :

Over many decades it has been accepted that the most economical way to produce a pipeline is to join together the standard lengths of pipe as quickly as possible, using a highly mobile task force of welders and other technicians, leaving tie-ins, crossings, etc. to smaller specialist crews. The work pattern which evolved almost invariably involved several crews of welders strung out along the pipelines, progress being controlled by the rate at which the leading pair could complete the weld root. The spread from this first crew to final inspection could be a considerable distance, acceptable on land but not acceptable offshore (a rapidly increasing need which reached a peak in the 1970's). This operation, involving costly lay barges, demanded even higher throughput rates to be achieved from a more compact working spread. In common with most manufacturing technologies, there was an increasing dissatisfaction with a system which relied entirely on the skill of a limited number of highly paid men who had little incentive to change their working practices. Increasingly there came reports of the development of new approaches to joining line-pipe, ranging from the mechanization of arc welding to entirely different forms of joining, for example, electron beam welding or mechanical joining. The investment in some of these developments is reported to be several million dollars. The review of present pipelining practice shows that only a handful has been put to practical use, and in the western world, probably only one, an arc welding variant, has been used to produce more than a few hundred miles of pipeline. The information available on these developments is sparse and is scattered amongst a range of companies and research agencies. A literature review and research study to collect together as much of this information as is available, assemble it into a coherent and useable form and identify those developments which show the most promise to fulfill future needs. The main body of the report, which reviews development of the welding processes has been divided into three main joining categories, Fusion Welding, Forge Welding and Mechanical Interference Joining. Within each category each process is considered separately in terms of process principles, general applications, application to pipeline welding, equipment for pipe welding, consumables, process tolerance and skill requirements, weld quality and inspection, process economics, limitations and future developments. This study and comprehensive report compares the economics of the various alternatives. For each process an estimate has been made of the procedural and development costs involved as well as personnel needs and likely production rates.

Résumé :

We believe the climate crisis will be resolved in cities. Today, while cities occupy only 2% of the Earth's surface, 57% of the world's population lives in cities, and by 2050, it will jump to 68% (UN, 2018). Currently, cities consume over 75% of natural resources, accumulate 50% of the global waste and emit up to 80% of greenhouse gases (Ellen MacArthur Foundation, 2017). Cities generate 70% of the global gross domestic product and are significant drivers of economic growth (UN-Habitat III, 2016). At the same time, cities sit on the frontline of natural disasters such as floods, storms and droughts (De Sherbinin et al., 2007; Major et al., 2011; Rockström et al., 2021). One of the sustainability pathways to reduce the environmental consequences of the current extract-make-dispose model (or the "linear economy") is a circular economy (CE) model. A CE is defined as "an economic system that is based on business models which replace the 'end-of-life' concept with reducing, alternatively reusing, recycling and recovering materials in production/distribution and consumption processes" (Kirchherr et al., 2017, p. 224). By redesigning production processes and thereby extending the lifespan of goods and materials, researchers suggest that CE approaches reduce waste and increase employment and resource security while sustaining business competitiveness (Korhonen et al., 2018; Niskanen et al., 2020; Stahel, 2012; Winans et al., 2017). Organizations such as the Ellen MacArthur Foundation and Circle Economy help steer businesses toward CE strategies. The CE is also a political priority in countries and municipalities globally. For instance, the CE Action Plan, launched by the European Commission in 2015 and reconfirmed in 2020, is a central pillar of the European Green Deal (European Commission, 2015, 2020). Additionally, more governments are implementing national CE strategies in China (Ellen MacArthur Foundation, 2018), Colombia (Government of the Republic of Colombia, 2019), Finland (Sitra, 2016), Sweden (Government Offices of Sweden, 2020) and the US (Metabolic, 2018, 2019), to name a few. Meanwhile, more cities worldwide are adopting CE models to achieve more resource-efficient urban management systems, thereby advancing their environmental ambitions (Petit-Boix & Leipold, 2018; Turcu & Gillie, 2020; Vanhuyse, Haddaway, et al., 2021). Cities with CE ambitions include, Amsterdam, Barcelona, Paris, Toronto, Peterborough (England) and Umeå (Sweden) (OECD, 2020a). In Europe, over 60 cities signed the European Circular Cities Declaration (2020) to harmonize the transition towards a CE in the region. In this policy brief, we provide insights into common challenges local governments face in implementing their CE plans and suggest recommendations for overcoming these. It aims to answer the question: How can the CE agenda be governed in cities? It is based on the results of the Urban Circularity Assessment Framework (UCAF) project, building on findings from 25 interviews, focus group discussions and workshops held with different stakeholder groups in Umeå, as well as research on Stockholm's urban circularity potential, including findings from 11 expert interviews (Rezaie, 2021). Our findings were complemented by the Circular Economy Lab project (Rezaie et al., 2022) and experiences from working with municipal governments in Sweden, Belgium, France and the UK, on CE and environmental and social sustainability.
