Texte intégralWhile the tree growth potential is mainly determined by access to resources such as light or water, the distribution of produced biomass is under strong biomechanical control. The tree response to mechanical stimuli such as those induced by wind is called thigmomorphogenesis. This response has been mainly studied on very young trees under controlled condition, and only rarely in natural condition. This is the first study dealing with the tree growth in a broadleaf stand aiming to quantify the importance of thigmomorphogenetic effect as a growth factor in the silvicultural context. The experimental set-up includes forty trees divided into four groups of ten trees selected in a dense 35yrs old F. sylvatica L .stand. Each group was submitted to one of following treatments: thinning without guying, thinning with guying, guying only and controls.Considering the thigmomorphogenetic effect on the biomass allocation inside the tree, our results show that 45% of the stem volume growth and 61% of the root radial growth of thinned trees are due to wind-induced mechanical stimuli. Further, the distribution of tree ring area along the tree stem is under strong mechanosensitive control. In contrast, no effect of mechanical stimuli or thinning was observed on axial growth. Considering the explanation of the circumferential growth anisotropy, our results do not highlight a thigmomorphogenetic effect despite the identification of dominant sectors for strong winds and strains. The hypothesis put forward is that the directional variability of perceived strains is too high to induce a strongly directional growth response as it is usually the case under controlled conditions

Texte intégralThe Press Law of July 29, 1881 is one of the major “liberal” achievements of the French Third Republic. It has been amended regularly since its enactment to adapt to the needs of society and it is supposed to guarantee the freedom of expression while at the same time imposing some limitations, as there is no absolute freedom. The limitations to the freedom of expression seem legitimate in a democracy as long as they do not constitute a crime of opinion i. E. Prohibit an opinion which is considered as evil by the government in power. The original intent of the 1881 law-makers was to repeal and ban that type of offence. The subsequent set of acts which created new violations of the press laws, have however revived the debate because numerous observers have seen in it the resurgence of crimes of opinion. These studies can neverterless be discussed and moderated. Crime of opinion have definitely disappeared from the Press Law in favour of the resolution of legal disputes sometimes by the conciliation of the rights in conflict (the freedom of expression with the protection of public order and the rights of others), sometimes by the neutralization of one of the rights in conflict (example of revisionist speech). However, the persistence and the resurgence of crimes of opinion has to be acknowledged. Indeed, it has never completely disappeared from the Press Law, be it in the original law of 1881 or in the subsequent amendments. The law-makers even seem to have been followed by the judges who tend to be tempted, through the particular implementation of some violations of the law (abuse of religious feelings, defamation), to reintroduce those offences that are quite incompatible with democratic ideals

The objectives of this study were to determine the effect of enhancement on consumer and trained beef palatability scores of three quality grades when cooked to three degrees of doneness (DOD) and to determine the accuracy and repeatability of the Pressed Juice Percentage (PJP). Striploins of USDA Prime, Low Choice, and Low Select quality grades were used in this study. To maximize variation in juiciness, steaks were either enhanced (formulated for 108% pump with a solution of water, salt, and alkaline phosphates) or non-enhanced, and cooked to three degree of doneness (Rare: 60°C, Medium: 71°C, or Very Well-Done: 82°C). All samples were evaluated for Warner-Bratzler shear force (WBSF), Slice Shear Force (SSF), PJP, and palatability traits by consumer and trained panelists. Consumer panelists rated all enhanced treatments similar (P > 0.05) to each other and greater (P < 0.05) for juiciness, tenderness, flavor liking, and overall liking than all non-enhanced treatments. Consumer ratings of juiciness, tenderness, and overall liking scores increased (P < 0.05) as DOD decreased. Consumer panelists rated all enhanced treatments similar (P > 0.05) and greater (P < 0.05) for the percentage of steaks classified as premium quality. For trained panel initial juiciness, all enhanced treatments and non-enhanced Prime samples were similar (P > 0.05) and greater (P < 0.05) than other treatments cooked to Medium and Very Well Done. Results indicated PJP had a relatively high repeatability coefficient (0.70), indicating that only 30% of the variation observed was due to sample measurement differences. The PJP threshold values evaluated accurately segregated steaks by the probability of a sample being rated “juicy” by consumers, with the actual percentage of “juicy” samples determined to be 41.67%, 72.31%, 89.33%, and 98.08% for the <50%, 50 – 75%, 75 – 90%, and >90% categories, respectively. Therefore, enhancement has a substantial, positive effect on beef palatability. Enhancing higher quality beef does not provide an additional palatability benefit; hence the greatest economic advantage is in enhancing lower quality beef products. Results of this study indicate the PJP juiciness method is both repeatable and accurate at sorting steaks based on the likelihood of a steak being “juicy”.

Texte intégralIn this self-study, I explore my own learning process in musical composition during time pressure. Six compositions are written with three different deadlines: four days, two days and three hours. There are two compositions for each deadline. The study is based on a phenomenological perspective with supporting literature and scientific research on musical composition and the correlation between work and time pressure. This study uses log records and video observations as methods of documentation while thematic analysis is used to analyze the collected data. The result answers two questions: How I experience working with limited time? and What methods are used to finish in time? The result is split into four categories each after its own deadline: four day composition, two day composition and three hour composition. These four categories have two subcategories: The compositions method and the experience in composing with time pressure. In the discussion, these results are set in relation to the selected literature, research and the phenomenological perspective.

Texte intégralSolid Rocket Motors (SRMs) can display self-sustained acoustic oscillations driven by coupling between hydrodynamic instabilities of the internal flow and longitudinal acoustic standing waves. The hydrodynamic instabilities are triggered by the acoustic standing wave and results in the formation of coherent vortical structures. For nominal ranges of flow conditions the sound waves generated by the interaction between these vortices and the choked nozzle at the end of the combustion chamber reinforces the acoustic oscillation. Most available literature on this subject focuses on the threshold of instability using a linear model. The focus of this work is on the prediction of the limit-cycle amplitude. The limit-cycle is reached due to nonlinear saturation of the source, as a consequence of the formation of large coherent vortical structures. In this case the vortex-nozzle interaction becomes insensitive to the amplitude of the acoustic standing wave. Hence, one can focus on the sound generation of a vortex with the nozzle. Sound production can be predicted from an analytical two-dimensional planar incompressible frictionless model using the so-called Vortex Sound Theory. In this model the vorticity is assumed to be concentrated in a line vortex. Experiments indicate that the volume of cavities around so-called “integrated nozzles” have a large influence on the pulsation amplitude for large SRMs. This is due to the acoustical field normal to the vortex trajectory, induced by the compressibility of the gas in this cavity. As an alternative to the incompressible analytical model a compressible frictionless model with an internal Euler Aeroacoustic (EIA) flow solver is used for simulations of vortex-nozzle interaction. A dedicated numerical simulation study focusing on elementary processes such as vortex-nozzle and entropy spot-nozzle interaction allows a systematic variation of relevant parameters and yields insight which would be difficult by means of limit cycle studies of the full engine. A systematic study of the vortex-nozzle interaction in the case of a choked nozzle has been undertaken. The results are summarized by using a lumped element model for plane wave propagation, which is based on theoretical scaling laws. From EIA simulations it appears that sound due to vortex-nozzle interaction is mainly generated during the approach phase and that for the relevant parameter range there is no impingement of the vortex on the nozzle wall as has been suggested in the literature. Using an energy balance approach, a single fit-parameter model is formulated which qualitatively predicts limit-cycle observations in cold gas-scale experiments reported in the literature. Finally the Euler model is used to compare the sound production by vortex-nozzle interaction with that due to the ingestion of an entropy non-uniformity also called entropy spot. In addition to insight, this study provides a systematic procedure to develop a lumped element model for the sound source due to non-homogeneous flow-nozzle interactions in SRMs. Such lumped models based on experimental data or a limited number of flow simulations can be used to ease the design of SRMs

Texte intégralConcentration polarization of solute at the membrane surface, because of osmotic pressure effects, is an important phenomenon that can cause substantial reductions in permeation. To understand these phenomena: we first analyze the filtration process for a pure solvent, imposing the influence of the driving pressure on permeation at the membrane. We obtain accurate analytical solutions for the flow fields. We then derive an analytical solution that coupled hydrodynamics to mass transfer for filtration systems working in a situation of High Pressure and Low Recovery. Second, we develop a numerical model that incorporates both physical aspects: the dependency of pressure on permeation and the influence of concentration polarization and their related osmotic effects in the effective pressure at the membrane. For that, the numerical approach solves the solute conservation equation coupled with the Navier-Stokes equations under the steady Prandtl approximation. The solution of the system is performed using a finite difference method of order 2. The validity of this approach is successfully demonstrated with the previous analytical solutions for hydrodynamics, as well as for the coupling with mass transfer. We then test the influence of the main operating parameters (inlet concentration, axial flow rate, operating pressure and membrane permeability) on the performance of the filtration system and compare the results with other numerical models that takes into account concentration polarization phenomenon. Finally, the validity of this model is quantitatively well-proved when using the reported data resulting from reverse osmosis experiments

Thesis, Université Grenoble Alpes (ComUE), 2018. http://www.theses.fr/2018GREAL014/document.
Texte intégralThis work suggests to study the mobilization of popular speech during the media coverage of Egypt-Algeria match by the French-written generalist press and the Algerian specialized press. Our first observations on the treatment of the football event, lead us to suppose that the discourse of the newspapers of general information is not different from the dailies of sport. Thus, the research suggests grasping the strategies which frame the use of popular speech. It consists of analyzing the emergence of a communicational-info practice that can be part of a market penetration strategy seeking for an enlarged readership.The analysis of media acting skills, in press global crisis context foresees to show how they make use of popular speech, as a significant capitation pattern and a selling argument. To apprehend this issue, it seems necessary to situate this work in an approach that does not neglect the study of editorial identities of each press title.Therefore, we suggest to deconstruct the publications of four "reference" newspapers by defending a methodology based on theoretical aspects. That methodology is supplied by discourse analysis combined with quantified study of the event and supported by the visions of Algerian professionals’ media information.Key words: Media event, device, framework, co-construction, popular speech strategy, tactics, editorial identity and proximity law

Texte intégralThis thesis focuses on statistical tools for the assessment of maxima sloshing loads in LNG tanks. According to ship features, tank cargo and sailing conditions, a sloshing phenomenon is observed inside LNG tanks. The determination of sloshing loads supported by the tank structure is derived from impact pressure measurements performed on a test rig. Pressure maxima per impact, extracted from test measurements, are investigated. Test duration is equivalent to 5 hours in full scale. This duration is not sufficient to determine pressure maxima associated with high return periods (40 years). It is necessary to use a probabilistic model in order to extrapolate pressure maxima. Usually, a Weibull model is used. As we focus on extreme values from samples, fittings are also performed with the generalized extreme value distribution and the generalized Pareto distribution using block maximum method and peaks over threshold method.The originality of this work is based on the use of an alternate measurement system which is more relevant than usual measurement system to get pressure maxima and a 480 hours measured data available for same test conditions. This provides a reference distribution for pressure maxima which is used to assess the relevance of the selected probabilistic models. Particular attention is paid to the assessment of fittings quality using statistical tests and to the quantification of uncertainties on estimated values.The provided methodology has been implemented in a software called Stat_R which makes the manipulation and the treatment of results easier
Tran, Trung Hieu. « Élasticité des verres silicatés sous pression : étude par diffusion Brillouin ». Thesis, Montpellier 2, 2010. http://www.theses.fr/2010MON20181.
Texte intégralWe study the elastoplastic response of silicate glasses at high stresses with Brillouin light scattering. 3D micro-Brillouin mapping residual density field are obtained in the plastic region left by a Vickers indentation. Maps are compared with finite element modeling. The joint analysis of new high-pressure measurements in a diamond anvil cell on silica in the elastic domain and literature data revealed that the abnormal hardening of elastic moduli with temperature is of dynamical origin. The onset temperature of the hardening increases with increasing applied hydrostatic pressure. We also observe that densification of silica strongly reduces the amplitude of the maximum in internal friction observed at 2 GPa as well as it suppresses the compressibility anomaly

Texte intégralThe 1860s-1870s form a turning point in the history of British democracy, because these were the years when the second Reform Act was passed, which extended the right to vote to larger sections of the working classes. Such political change was the result of numerous national demonstrations organised by the Trades’ Unions. By showing their strong commitment to the Union during the American Civil War, and to Italian and Polish national unity, the working classes signalled their determination to enter the field of politics. This doctoral thesis studies the construction of working class citizenship through the pages of the Bee-Hive, a radical and liberal working class paper primarily created in 1861 to claim for suffrage

Esta pesquisa objetivou investigar a manifestação do isomorfismo nos Códigos de Ética das empresas de capital aberto listadas na Bolsa de Valores do Brasil para verificar como a construção deste documento é influenciada por mecanismos institucionais que exercem pressão sobre estas empresas, inseridas no mesmo ambiente.Foi realizada uma pesquisa qualitativa, de caráter descritivo, conduzida por meio de análise do conteúdo dos Códigos de Ética de uma amostra que incluiu todos os setores econômicos utilizados pela Bolsa de Valores do Brasil. Para tratamento dos dados, o estudo utilizou categorias referentes às exigências da Legislação Brasileira, à legitimidade e às melhores práticas de um Programa de Compliance.A partir das categorias evidenciadas no conteúdo dos Códigos de Ética, esta pesquisa observou a ocorrência dos aspectos de isomorfismo coercitivo e de legitimidade em todos os Códigos, independente do setor econômico das empresas da amostra. Este estudo sugere que os Códigos analisados foram criados como uma resposta simbólica para atender as pressões de regulação e do ambiente institucionalizado onde as empresas estão inseridas.A presente pesquisa se limitou a analisar os conteúdos dos Códigos de Ética sob a luz da Teoria Institucional, concentrando-se no aspecto do isomorfismo e dos mecanismos institucionais que exercem pressão sobre as organizações inseridas em determinado campo organizacional, não abordando outros conceitos da Teoria nem realizando qualquer análise sobre a efetividade dos Códigos de Ética nas organizações selecionadas.O resultado deste estudo serve como um insumo relevante tanto para empresas que necessitam construir seu Código de Ética, quanto para as que necessitam aperfeiçoar o conteúdo de Códigos de Ética já existentes.As empresas podem construir seu Código de Ética como um guia efetivo de conduta para restringir comportamentos não éticos da organização e não apenas como um documento escrito para atender as exigências institucionais e regulatórias.Pelo nosso conhecimento, este é o primeiro estudo de conteúdo dos Códigos de Ética das empresas de capital aberto no Brasil, após a Legislação Brasileira Anticorrupção.
The purpose of this study is to investigate the occurrence of isomorphism in the Codes of Ethics of public companies listed on the Brazilian Stock Exchange to verify how the construction of this document is influenced by institutional mechanisms that put pressure on these companies, inserted in the same environment.A qualitative, descriptive research was carried out by analyzing the content of the Codes of Ethics of a sample that included all the economic sectors used by Brazilian Stock Exchange. For data treatment, the study used categories related to the requirements of the Brazilian Legislation, related to legitimacy and to the best practices of a Compliance Program.From the categories evidenced in the content of the Codes of Ethics, this study observed the occurrence of coercive isomorphism and legitimacy aspects in all Codes, regardless of the economic sector of the sample companies. This work suggests that the Codes analyzed were created as a symbolic response to address the pressure of regulation and the pressure of the institutionalized environment where the companies are inserted.This study was limited to analyze the content of the Codes of Ethics using the Institutional Theory, focusing on the aspect of the isomorphism and the institutional mechanisms that put pressure on the organizations inserted in a determined organizational field, not addressing other concepts of the Theory nor performing any analysis on the effectiveness of the Codes of Ethics in the selected organizations.The result of this study serves as a relevant input for both companies that need to build their Code of Ethics and those that need to improve the content of existing Codes of Ethics.Companies can build their Code of Ethics as an effective conduct guide to restrict employees’ unethical behavior and not just as a written document to meet institutional and regulatory requirements.To our knowledge, this is the first study of the Codes of Ethics content of public companies in Brazil, after the creation of the Brazilian Anti-Corruption Law.
Manivannan, Sivaprasath. « Measuring permeability vs depth in the unlined section of a wellbore using the descent of a fluid column made of two distinct fluids : inversion workflow, laboratory & ; in-situ tests ». Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLX086/document.
Texte intégralIn wells producing water, oil, gas or geothermal energy, or in access wells to hydrocarbon storage, it is critical to evaluate the permeability of the formation as a function of depth, to improve the reservoir model, and also to identify the zones where additional investigation or special completions are especially useful.A new technique is proposed, consisting of scanning the open hole (uncased section of the wellbore) with an interface between two fluids with a large viscosity contrast. The injection rate into the formation depends on interface location and well pressure history. An inverse problem should be solved: estimate permeability as a function of depth from the evolution of flow rates with time. The wells are usually equipped with a central tube. The scanning is done by injecting a liquid in the central tube at constant wellhead pressure. Injection and withdrawal rates are measured at the wellhead; the difference between these two rates is the formation injection rate.To validate and improve this technique, we used a laboratory model mimicking a multi-layer formation, already available at LMS. We also made use of in-situ tests performed on an ultra-low permeable cap rock above an underground gas storage reservoir. In these tests, a viscous fluid contained in the open hole was displaced by a less-viscous fluid (a method called opening WTLog). The more permeable layers were correctly identified (Manivannan et al. 2017), but a quantitative estimation was challenging due to transient phenomena in the vicinity of the wellbore (near-wellbore zone). In addition, the investigation radius was small.These challenges are addressed by proposing a slightly modified test procedure and a new interpretation workflow. Laboratory tests with a modified test setup showed the advantages of the ‘closing’ method in which the well is filled with a less-viscous fluid at the start of the test. We also added a stabilization period before the injection of viscous fluid to minimize the transient effects; this period is also used to estimate the average permeability of the open hole and the effect of near-wellbore damage (skin).Then the test proper is performed (closing WTLog). The injection profile of the less-viscous fluid is computed from the wellhead flow rate history. A permeability profile is estimated from the injection profile. The permeability estimation considers a monophasic flow in each layer and the same skin value for all the formation layers. Major uncertainties in the permeability estimates are caused by formation pressures and heterogeneities in skin values; they are estimated using an analytical formula. We have verified on the laboratory setup that the estimated permeability profiles are well correlated to the permeabilities measured before the tests.An attempt was made to perform a WTLog in a 1750-m long wellbore opening in a salt formation. The first phase was successful and the average permeability was correctly assessed. However, this permeability was so small (4.0E-21 m² or 4 nD) that the gauges and the flowmeters were not accurate enough to allow a clear distinction between the permeabilities of the various parts of the open hole

Texte intégralThis work deals with the acoustical properties of systems incorporating Micro-Perforated Panels (MPP) and absorbing materials under high level of excitation.In the first chapter, absorbent systems composed of an air-cavity backed MPP are studied at high level of excitations. An analytical model involving two dimensionless parameters and an optimum Mach number is proposed. This model describes the behavior of the maximum of absorption coefficient (absorption coefficient at the resonance) with respect to the Mach number inside the perforations. A formula is proposed that predicts the variations of the absorption peak with the acoustical Mach number.In the second chapter, the holes interaction effects are studied theoretically and experimentally under high levels of excitations. Following an equivalent fluid approach, a model for which the tortuosity is corrected to account for the holes interaction effects coupled to the jet-like effects is developed. Multi-layered absorbents composed of MPP and porous materials are then studied under high level of excitations. The case where the multi-layers are directly attached to a rigid wall and the case where there is an air cavity before the rigid wall are examined. Forchheimer's law is used to model each medium of the multi-layer and the use of the transfer matrix method is made to account for these media.Sound transmission study under high level of excitation is introduced. The perspectives of this work are numerous and promising in the acoustics of transportation systems applications
Hahn, de Bykhovetz Bérénice. « Les faits justificatifs de la diffamation ». Thesis, Paris 2, 2018. http://www.theses.fr/2018PA020045.
Texte intégralThe special justifications applicable to defamation bare witness to the difficult conciliation between the right to protect ones honor and the public’s right to information. The area of the defence of truth (art. 35 of the 29 July 1881), delineated by three exceptions in 1944, was rapidly critiqued, preventing the justification of some of the most socially useful imputations. Furthermore, the defence of truth was subjected to highly rigourous formal and substantial requirements that often prevented ones acquittal on the basis of that demonstration. In reaction, the case-law created another special justification for defamation, based on good faith, and founded on four accessible criterias (legitimate aim of the information, serious verification, moderation of tone and caution in the choice of words, lack of personal animosity) that favorise the public’s right to quality information. At the end of the 20th century, this system was profoundly questioned, as being against the case-law of the CEDH, that requires a stronger protection of freedom of speech (article 10 CESDH) in connexion with debates of general interest or political discussions. Consequently, the Constitutional council repealed two of the three limits within the defence of truth, which is now only forbidden in the area of ones private life. This new arbitration between the two conflicting values doesn’t seem satisfying, especially since the defence of truth is still impeded by drastic conditions. In 2008, the Court of cassation integrated in a radical manner the CEDH criterias to its case-law on good faith. The case-law today steers towards a more balanced formula, founded on a proportional application of the four traditional criterias corrected in the light of the principes of the CEDH. However, the Court of cassation equally applies the CEDH criterias to other detrimental offences towards the freedom of expression, that do not benefit from the structural support of the special justifications of defamation. For those offences, instead of adopting the envisioned control of proportionality, it is proposed to create a generic justification, founded on the article 10 of the CESDH, that would be more consistent with the logic of criminal law

Texte intégralThe legal approach to the notion of creation is vague. It is traditionally considered in the light of intellectual property rights (copyright, patent, design, etc.), but this approach is insufficient. Fundamental rights show us this. They let us distinguish between its different dimensions: creation as both a human activity (a creative act) and an object of property (a creative good). The freedom of creation protects and ensures the creative act. However, the nature of the former remains unclear. It fluctuates between falling within the freedom of expression and the freedom to conduct a business. Furthermore, the proportionality test leads to the limits of creative freedom being examined in terms of “laws of the creative type”. Fundamental rights then require us to go beyond the concept of the creative act as a message.The creative good is protected by property law. Fundamental rights, however, bring into question the French concept of a creative good by further emphasising their economic aspect. Moreover, the proportionality test means retracing the boundaries of property law by taking into account its social functions. Fundamental rights therefore blur the line between property law and unfair competition law

Accurately predicting the maximum preconsolidation pressures for compressible clay strata is helpful to understand their stress histories and behaviors after applying loads. Thus, via the results of consolidation tests, many methods can be found in the literature for predicting the maximum preconsolidation pressure. Following those methods addressed in the literature, a modified one is proposed in this thesis. Then, the accuracy for each method is evaluated by utilizing some test results that the maximum preconsolidation pressures were known. Finally, consolidation test results for a brown clay performed during this study and sixteen others obtained from the literature are used to investigate the deviation for the predicted results from different methods. Results from this thesis indicate that the author’s method can produce better result. The reason for the above is that the effect of the over-swelling by absorbing water after fully unloading while sampling is less when the author’s method was adopted.

When the influence of the angle of internal friction was considered, Terzaghi (1943) and Lambe and Whitman (1969) found that the sliding failure plane for the cohesiveless backfill is close to a log spiral curve. Therefore the author of this thesis utilizes three line segments to form a curve which is close to a log spiral one to formulate an equation for calculating the coefficient of passive earth pressure. The differences between the newly resulting coefficients of passive earth pressure and those obtained from the Coulomb’s equation for a planar sliding failure plane can then be investigated. Results from this thesis indicate that (1) when the inclination angles for the back of wall are 60°, 65°, 70°, 75°, and 80°, the resulting coefficients of passive earth pressure from a planar sliding failure plane are greater than those from a near log spiral plane; and, the maximum difference can be as large as 106.25%; (2) when the inclination angle for the back of wall is 90°, the resulting coefficients of passive earth pressure from a planar sliding failure plane can be greater or less than those from a near log spiral plane; and, the maximum difference is reduced to 1.45%; (3) when the inclination angles for the back of wall are 95°, 100°, 105°, 110°, 115°, and 120°, the resulting coefficients of passive earth pressure from a planar sliding failure plane are less than those from a near log spiral plane; and, the maximum difference can be as large as 108.98%.

Texte intégralIt is generally believed that media messages influence the perceptions of audiences. Thus, they contribute to identity formation and to social cohesion. However, research in Canada has often found discrepancies in coverage by Quebec and English-Canadian media. This media divide has been suspected of amplifying the differences between the two communities. Yet, research on the differences between the Francophone and the Anglophone press in Quebec is limited. This thesis poses the question whether a linguistic divide also exists in the Quebec media landscape. For this purpose, we identified the frames mobilized by French- and English-language newspapers. We understand frames as interpretative schemata proposed by the media to make sense of news events. To verify our hypothesis that frames differ in the English and French language media of Quebec, we analyzed the coverage of Bill 14 by ten newspapers during 50 weeks. Using a mixed method, which combined a computer-assisted and a qualitative analysis using Van Gorp’s (2005) frame matrix, we identified linguistic, social, political, pragmatic and sovereignist frames. Our results show that four of these frames were used by both French- and English-language newspapers and that the media partially took up discourses from the other language community. However, the two groups prefer different frames and articulate them differently. The rapprochement of Anglophone and Francophone media in Quebec is thus limited, among other things, by diverging historic experiences and activism by community newspapers.

This creating discourse aims at discovering artworks, and making people enjoy the rationality and sensibility that it brings. Also, it is a release and appreciation of senses. By the expression of techniques, artists make natural scenery and plants created by the God become the original colors, lines and figures, which lively show on canvas or other tridimensional creation, and they are memories deeply rooted in our mindas well. We research into, first, the way realistic artworks of memory gradually become representational, imaginary, and abstract; second, how theychange from complexity into simplicity. Finally, the interpretation lies in the beauty of characters and the subtle communication when tridimensional vases (lacquer and pottery) gently stare at each other. All the memories are transformed to creation; through media and techniques, all happiness, sadness and other realization toward life are thoroughly shown. The colors, lines and figures symbolize the aspiration of the world, comparing and insinuating our inner and secret feeling. I do my utmost to think outside the box, having revolutionary ideas of the pressed flower artworks. Moreover, I get rid of realistic and naturalistic creation and connect birds, mountains, grand trees, which have long symbolized freedom and reliance, into my works by metaphors. The works are simplified based on different phases;transforming into geometric drawing and abstract concepts. Also, I learn how Paul Klee completed his works with intense and black lines and apply it in my drawing. Not only do I draw by pens, but use ready-made pressed flowers to show the lines. Most of the time, Paul Klee observed the nature, extracted its nutrients, and put them into his works. What makes me totally impressed is the theme of his happiest period in hisart career, which includes the painting poetry of plants and animals and his diverse techniques. This style inspires me to observe the creatures in nature, combining their figures, sounds, and meaning with the beautyof lines and stylish decoration of Chinese characters. Through the creation by multimedia, these works make people recall their wonderful memories, comfort their pain, and insinuate the fact that people are materialistic and in pursuit of fame most of their life. More importantly, the art shows that human are as fragile as pressed flowers, because all materials and fame that human chase after will finally wither when they die. Eventually, the greatest value of life is onlylove, which is immortal and eternal.

Pork loin is a good source of protein. The edible part of burdock is the root, which is rich in moisture carbohydrates, dietary fiber and other nutrients. High hydrostatic processing (HHP) and sous-vide cooking (SV) are the novel processing technologies. HHP uses water as a transfer medium to apply the ultra-high pressure on the food packed in a soft and closed container. The SV method uses a precisely controlled water bath to cook the vacuum-packed food. Both techniques could modify the texture and preserve the flavor and nutrients of foods. The objective of this research is to study the effects of HHP、 SV and frozen storage on the physicochemical properties of pork loin and burdock. The burdock was washed and the 2 cm diameter portion was cut and peeled. The peeled burdock was then cut into small pieces with about 2 cm height. The small burdocks were immersed in a mixture of 0.2% citric acid and 10% brine for 30 minutes and SV-cooked at 80 and 90 ℃ for 2, 4, and 6 hours. The pork loin was cut into 2×2×2 cm3 cubes. The pork samples were marinated with kiwifruit powder and soy sauce at 4 ℃ for 2 hours and subjected to HHP at the pressure of 350 MPa for 3 min. The HHP treated samples were then cooked by using SV method at 60 and 70 ℃ for 6, 12, 18, and 24 hours. Cooked meat was stored at – 20 ℃ for 6 months. The samples without HHP treatment were used as control. The physicochemical properties of samples including appearance, size, cooking loss, color and texture were evaluated. The results showed that the cooking loss of burdock with SV-cooked at 80 ℃ was less and the texture was harder and more work of compression than that of burdock with SV-cooked at 90 ℃. The cooking loss, hardness, and work of compression of burdock were decreased with cooking time. Moreover, the size of cooked burdocks was not different significantly. The weight of pork pieces with SV-cooked at 70 ℃ was more and the weight of residue was less than those of pork pieces and residue with SV-cooked at 60 ℃. The integrity of pork pieces with SV-cooked at 70 ℃ was better retained. The cooking loss of SV-cooked meats increased but the hardness and chewiness decreased significantly with cooking time. The pH, water activity, and texture of SV-cooked meats did not change obviously during 6 mouths of storage. The pork pieces with HHP treatment were smaller and the cooking loss and the weight of residue were higher than control. In conclusion, immersion and sous-vide cooking can retain a better appearance and soften the texture of burdock. The texture of meat could be modified by the addition of kiwifruit powder with HHP and SV treatments.

Texte intégralOur research aimed to understand the emergent dimensions of an organization’s image construction. Following the review of existing research literature, we are interested in the refracted image, which is the image of an organization built by a specific public named external arbiters. These external arbiters are mandated organizations that disseminate information to the general public. By adopting a qualitative approach, we conducted a study about the case of the implementation of Bill C-38 by the Canadian Federal Government. Specifically, we examined the working process of two arbiters communities : journalists working for different newspapers, and environmental organizations’ members. The empirical study has allowed us to propose a conceptual model of the construction of the refracted image phenomenon. We thus suggested to observe this phenomenon through the actors’ working practices to understand the emergence of the image dynamics. Also, we emphasized the relevance to consider factors that constitute the framework within which the working process of the actors belonging to different public communities takes place. For it is these parameters that generate the various dynamics regulating the organizational image’s construction by each public community.

Texte intégralPressure drop within a field can be attributed to several factors. Pressure drop occurs when fractional forces cause resistance to flowing fluid through a porous medium. In this thesis, the sciences of petrophysics and rock physics were employed to develop understanding of the physical processes that occurs in reservoirs. This study focussed on the physical properties of rock and fluid in order to provide understanding of the system and the mechanism controlling its behaviour. The change in production capacity of wells E-M 1, 2, 3, 4&5 prompted further research to find out why the there will be pressure drop from the suits of wells and which well was contributing to the drop in production pressure. The E-M wells are located in the Bredasdorp Basin and the reservoirs have trapping mechanisms of stratigraphical and structural systems in a moderate to good quality turbidite channel sandstone. The basin is predominantly an elongated north-west and south-east inherited channel from the synrift sub basin and was open to relatively free marine circulation. By the southwest the basin is enclose by southern Outeniqua basin and the Indian oceans. Sedimentation into the Bredasdorp basin thus occurred predominantly down the axis of the basin with main input direction from the west. Five wells were studied E-M1, E-M2, E-M3, E-M4, and E-M5 to identify which well is susceptible to flow within this group. Setting criteria for discriminator the result generated four well as meeting the criteria except for E-M1. The failure of E-M1 reservoir well interval was in consonant with result showed by evaluation from the log, pressure and rock physics analyses for E-M1.iv Various methods in rock physics were used to identify sediments and their conditions and by applying inverse modelling (elastic impedance) the interval properties were better reflected. Also elastic impedance proved to be an economical and quicker method in describing the lithology and depositional environment in the absence of seismic trace.

Texte intégralThis dissertation is framed in the context of translation history in Colombia during the 19th century. It articulates the relationship between translation and education during the education reform implemented by the radical wing of the Colombian Liberal Party known as los radicales. In order to explore such relationship, the translations published in La Escuela Normal (1871-1879) are described and analyzed. This periodical, an official publication organ of the Radical administration, had as its goal to disseminate administrative and legal information concerning the education reform. It also became a vehicle for the publication of articles of pedagogical nature and of lessons about different subjects, intended to be used for teacher education (textbooks). By proposing a descriptive, socio-cultural theoretical framework and methodology, which combines the analysis both of translations and the context of their reception, this study explores how and why the political, social, and educational context of the time influenced the choice of topics and authors to be translated for the periodical. It also examines the group of translators and intellectuals that contributed to the publication, as well as their translation strategies. This study presents translation as an activity that is not neutral, but is actually enmeshed in social and cultural dynamics. Furthermore, cultural exchanges foster all kinds of transfers, ranging from the adoption of social models and representations to the practice of translation proper. In the end, translation reveals itself as a tool at the service of the interests of a given political and social group.

Texte intégralThis masters’ thesis analyses the connections between the first allied military trials held in postwar Germany and German public opinion toward the British and American occupation forces. Focused on the Belsen trial, held in the British occupation zone from September to November 1945, and the Dachau trial, held by the American military government in the U.S. occupation zone between November and December 1945, this study seeks to highlight the importance both trials held for the British and the Americans in establishing positive relations with the Germans. Using Belsen and Dachau as case studies, it argues that, while they were essential to British and American denazification and re-education programs, they also had to be conducted in a manner that ensured the best possible relationship the German public and the occupation forces in both the American and British occupation zones. I demonstrate that, from the initial steps implemented to set up the trials through their conclusion, both powers took German concerns and reactions to the judiciary procedures into account: first by anchoring the charges and the trials themselves in international law preceding the Second World War; then by providing the right to a defense to the accused. Both factors, the Allies believed, allowed them to claim a moral authority over their occupation zone. The memoir’s examination of the trials and their purpose is complimented by an analysis of the press coverage of the trials and public opinion surveys taken after the trials. This study states that the press coverage was oftentimes one the first instances in which Germans were confronted to the atrocities committed in the concentration camps. Finally, this study argues that, as a part of larger programs, the trials had a limited success as a tool to implement positive relations between the British and American occupation forces and the German population.
