Henrichon, Stephen E. "Ernest Hemingway’s Mistresses and Wives: Exploring Their Impact on His Female Characters." Scholar Commons, 2010. http://scholarcommons.usf.edu/etd/3663.
Full textAbstract:
“Conflicted” succinctly describes Ernest Hemingway. He had a strong desire to
make his parents proud of him but this was in constant conflict with his need to tell a
story, warts and all. Of particular importance is his relationship with his mother and the
crippling effect it has on his relationships with women. Hemingway’s life becomes a
series of dysfunctional relationships that fail to meet his needs, leaving him perpetually
searching for the right woman. Kert posits that Hemingway’s contempt for women is
related to his inability to make the transition from lover to husband, fueled by
Hemingway’s belief that his father surrendered his manhood to Grace Hemingway.
Ernest, haunted by his parents’ relationship continues to associate negative connotations
with the term “husband,” leaving Hemingway in constant fear of becoming his father,
poisoning his marriages, and coloring the relationships Hemingway depicts in his short
stories.
Evident across the arc of Hemingway’s short stories is an evolution in his skill as
a writer, but also in the development of his female characters. Over his career,
Hemingway develops a female voice that rings true, and he skillfully uses it to portray
female characters who are evolving into strong self-reliant women. In these stories, there
is a gradual shift in the dynamics of the relationships as Hemingway’s fictional women
struggle to climb from under their man’s domination. Yet, these strong self-reliant
women are not fully accepted by Hemingway’s male characters, leaving a palpable
tension between Hemingway’s fictional men and women. This tension can be attributed
to Hemingway’s ongoing love/hate relationship between himself and the self-reliant
women in his life.
Hemingway never recovers from the emotional damage inflicted by his mother,
evident in his personal life and in the dysfunctional relationships in his short stories. He
remains vigilant and is concerned that he will end up like his father and be controlled by
a domineering bitch. However, Hemingway exerts so much control in his relationships
and becomes a version of his mother as he dominates his significant others. In his life, he
transitions from an angry resentful child-man to a young husband, a reluctant parent, a
ladies’ man, and an adventurer. Likewise, his perception and portrayal of women in his
short stories keeps pace with his personal experiences. These female characters
sometimes reflect the women in his life and sometimes reflect Hemingway’s insecurities
as a man, and often a seamless melding of both.

Full textAbstract:
O preparo do canal radicular visa a remoção de bactérias que podem causar a patologia periapical, e os instrumentos endodônticos estão sendo constantemente aprimorados para tornar o tratamento do canal radicular mais fácil, rápido e seguro. Assim, novos instrumentos precisam ser avaliados quanto ao seu desempenho. O objetivo deste estudo foi avaliar a remoção bacteriana dos sistemas Wave One Gold e One Shape New Generation comparando-os com seus sistemas predecessores. Cinquenta e seis canais disto vestibulares de molares superiores esterilizados por oxido de etileno foram contaminados com Enterococcus faecalis por 21 dias, e então uma amostra bacteriana inicial foi coletada e paqueada em M-enterococcus agar para contagem bacteriana em unidades formadoras de colônias. Os espécimes foram aleatoriamente divididos em quatro grupos de acordo com a instrumentação (n=12): Wave One Gold Primary, One Shape New Generation 25/.06, Wave One Primary e One Shape 25/.06, e os outros 8 canais não contaminados foram o controle de assepsia. Todos os grupos utilizaram água destilada como irrigante. Nova coleta foi feita imediatamente após a instrumentação e aos 7 dias. A redução bacteriana foi calculada em porcentagem, e então feita análise intragrupo pelo teste de Wilcoxon e entre grupos por Kruskal Wallis e teste de Dunn, todos com significância de 5%. Todos os sistemas reduziram significativamente a carga bacteriana do canal radicular tanto na coleta imediata quanto aos 7 dias (p<0,05). Houve aumento do número de bactérias 7 dias após o preparo quando comparado com a coleta imediata (p<0,05). A análise entre grupos mostrou que Wave One Gold e One Shape New Generation promoveram maior redução bacteriana que os sistemas Wave One e One Shape (p<0,05), sem diferença significativa entre Wave One Gold e One Shape New Generation ou entre Wave One e One Shape (p>0,05). Conclui-se que Wave One Gold e One Shape New Generation promoveram maior remoção bacteriana do que seus sistemas predecessores.The root canal preparation aims to remove the bacteria that can cause periapical pathologies, and endodontic instruments are constantly being improved to make root canal treatment easier, faster and safer. Thus, new instruments need to be evaluated for their performance. The aim of this study was to evaluate the bacterial removal promoted by Wave One Gold and One Shape New Generation systems in comparison to that of their predecessor systems. Forty-six distobuccal root canals of upper molars sterilized with ethylene oxide were infected with Enterococcus faecalis for 21 days, and then root canal initial bacterial sampling was collected and plated on M-enterococcus agar to bacterial count in colony forming unities. The specimens were randomly divided into four groups according to the instrumentation (n=12): Wave One Gold Primary, One Shape New Generation 25/.06, Wave One Primary and One Shape 25/.06, and the other 8 uncontaminated canals were used as asepsis control. All groups used distilled water as irrigant. New sampling was obtained immediately after instrumentation and at 7 days. The bacterial reduction was calculated in percentage, after that intra-group analysis was carried out by Wilcoxon test, and inter-group analysis by Kruskal-Wallis complemented by Dunn\'s test, all at 5% significance. All the systems significantly reduced the bacterial amount in the root canal in both immediate and at 7 days sampling (p<0.05). The bacterial amount increased at 7 days after preparation comparing to immediate sampling (p<0.05). The analysis between groups showed that Wave One Gold and One Shape New Generation promoted greater bacterial reduction than Wave One and One Shape systems (p<0.05). No significant difference was found between Wave One Gold and One Shape New Generation or between Wave One and One Shape (p>0.05). It can be concluded that Wave One Gold and One Shape New Generation promote greater bacterial removal than their predecessor systems.

Full textAbstract:
Since 1985, the direct job creation efforts of the federal government have been targeted on the long term unemployed, under the Job Development Program, in response to the increased incidence of long term unemployment since the recession. This research was initiated to provide early feedback on a program of individually subsidized jobs, as a demand-side employment initiative targeted on individuals who had been unemployed for approximately six months.
The research was a descriptive analysis of the experience of 64 program participants, in an area of Vancouver with a high ethnic population where there is traditionally high unemployment. An experimental, uncontrolled, single group design was used to compare client characteristics as program input, as well as program intervention, agency administration and labour market conditions, to program outcomes.
The variable that demonstrated the strongest association with outcome was the relative demand for labour in the local labour market in which the job had been subsidized. There was also evidence from the research that factors within the subsidized job setting may influence the successful re-adaptation of long term unemployed individuals into the work force. The opportunity for career advancement as well as supervision on-the-job that is supportive of the individual who is re-adapting to a work environment, was each positively-correlated with program outcome.
While the results were inconclusive for some of the client characteristics measured in the study, others were clearly found to be poor predictors of program success.
Targeted job creation strategies like the Individually Subsidized Job program, respond not only to cyclical unemployment but address issues of structural unemployment through the targeting of these employment initiatives on employment disadvantaged groups. Although only tentative judgements can be drawn from the research, it suggests that program administration which is sensitive to labour market conditions, as well as to conditions within the job site itself, may improve the outcome of public employment initiatives.Arts, Faculty of

Full textAbstract:
Besshi-type deposits range in age from early Proterozoic to early Tertiary, of which the largest number are late Proterozoic, early Palaeozoic or Mesozoic in age. No Archaean examples of Besshi-type deposits are known, probably due to insufficient availability of sialic crust for erosion and clastic marine sedimentation before the start of the Proterozoic. All Besshi-type deposits are contained within sequences of clastic sedimentary rock and intercalated basalts in a marine environment. The basalts and amphibolites are principally tholeiitic in composition. Besshi-type deposits characteristically form stratiform 1enses and sheet-like accumulations of semi-massive to massive sulphide. The main ore assemblage consists dominantly of pyrite and/or pyrrhotite with variable amounts of chalcopyrite, sphalerite and trace galena, arsenopyrite, gold and e1ectrum, barite being absent in general. The median Besshi-type deposit (n=75) contains 1.3 million tonnes (Mt) of massive sulphide with a Cu grade running at 1.43%. It is suggested that Besshi-type deposits form by both exhalative and synsedimentary replacement processes when considering geological features and comparisons with modern analogues in the Guaymas Basin, Middle Valley and Escanaba Trough. The currently forming metalliferous sediments in the Red Sea provide for a brine pool model explaining the lack of footwall feeder zones below sheet-like deposits. Where thick sulphide lenses are contained in some Besshi-type deposits, combinations of exhalative precipitation and sub-sea-floor replacement of permeable sediments and/or volcanic rocks, take place in the upper parts of submarine hydrothermal systems.

Full textAbstract:
Little data exist on continuing professional education (CPE) participation among geoscientists. This study sought to establish an understanding of CPE participation amongst geoscientists through their behaviour, attitudes toward CPE and felt need of CPE. Members in the Mineral Deposits Division (MDD), an affiliate of the Geological Association of Canada (GAC), were used as the population for the survey. A mail survey questionnaire of the 819 members of MDD produced a response rate of 72%.
The findings revealed the majority of geoscientists held positive attitudes toward voluntary participation in CPE. The respondents participated in both instructional and informal activities such as, attending field trips and reading professional journals. Eighty percent of the respondents indicated having participated in instructional CPE activities during the previous 12 months, with a mean of 6 activities. In addition, 100% reported participating in the informal activity of reading professional journals for an average of 0.5 hours per week. Contrary to findings in the literature, no significant relationships were found between educational level, attitude, occupational positions, barriers to participation and the extent of CPE participation. These findings reflect the homogeneity of the
sample's socio-economic status: high education levels (39% B.A's/B.Sc's, 32% M.A's/M.Sc's and 27% PhD's), with a mean income of $44K. The general character of a MDD member is one who specializes in geology (68%), works for industry (60%), holds an occupational position of either project geoscientist or middle management (57%). Few barriers to participation were identified: scheduling difficulties and lack of time.
The anticipated future of the geoscience profession was reflected in the perceived CPE needs of the group. Geostatistics (59%), oral presentations (49%), mining laws (50%), and geochemistry (49%), were items most frequently cited.
Sixty five percent reported that sponsors of CPE other than their own institution were better providers of CPE activities. Although the lecture format was the most frequented CPE format during the previous year, field trips were the preferred format. T.V and video as CPE delivery systems were not favoured by geoscientists which contrasts trends amongst other professionals, particularly engineers in the United States (Greenburg & Beidenburg, 1987).
These findings are of importance to those in geoscience who sponsor, plan, provide, or evaluate CPE activities, but particularly the MDD in developing its CPE policy, and to those in the field of adult education conducting participation research because data has been gathered specifically pertaining to mineral deposit geoscientists in
Canada. Recommendations were proposed for the national umbrella organization, the Canadian Geoscience Council, which has the structure and influence to establish CPE as a priority within geoscience in the areas of programme planning, CPE policy development and resource management.Education, Faculty of

Full textAbstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorDentinal defects are characterized by cracks in the root dentin that can develop into a vertical root fractures (VRF), thus leading to tooth loss. Endodontic procedures may generate these defects and between these steps, the biomechanical preparations with NiTi rotary instruments are associated with the incidence of these amendments dentinal. A new concept in minimally invasive preparation was introduced, along with a new reciprocating movement, using a single instrument for root canal instrumentation. This allows less root dentin is removed, thus avoiding the weakening of tooth structure. The aim of this study was evaluate the incidence of dentinal defects after root canal preparation by three single-file systems. One hundred forty mesial roots of mandibular molars were selected and randomly assigned to 4 groups (n= 35 mesial roots per group). One group was left unprepared as control. In two groups, the root canals were instrumented by using the reciprocating single-file systems WaveOne (Dentsply-Maillefer) and Reciproc (VDW), while other group was prepared with single-file of continuous rotation One Shape (Micro-Mega). The specimens were sectioned in 03, 06 and 09 mm from the apex with a low-speed saw under water cooling (IsoMet 1000 Precision Saw) and observed through a stereomicroscope (Zeiss Stemi SV6, Carl Zeiss) at a magnification of 20×. The pictures were recorded and evaluated by two blinded calibrated observers. The slices were categorized in: 0- No defects; 1- Others defects and 2 vertical root fracture. The dates were statistically analyzed with a significance level set at α = 0.05. The chi-square and Fisher exact tests were used to assess the differences between groups. No defects were observed in control group. All the experimental groups showed dentinal defects. The reciprocating files were associated with more defects than the continuous rotary file and control group (P < 0.05), but no significant difference between them (P = .115). VRF was observed only in the One Shape group. The results of this study suggest that the biomechanical preparation could cause damage in the root dentin and that the continuous rotary has a tendency to result in fewer defects compared to reciprocating files.
Defeitos dentinários são caracterizados por trincas na dentina radicular que podem evoluir para uma Fratura Vertical da Raiz (FVR), levando assim a perda do elemento dentário. O preparo biomecânico com o uso de sistemas rotatórios está associado com a incidência dessas alterações dentinárias. Atualmente, o uso de um único instrumento para a instrumentação dos canais radiculares juntamente com uma cinemática reciprocante tem sido introduzido. Desse modo, o objetivo desse estudo foi avaliar a incidência de defeitos dentinários causado por três sistemas de instrumento único. Cento e quarenta raízes mesiais de molares inferiores foram selecionadas e aleatoriamente divididas em quatro grupos (n= 35 por grupo). Um grupo não sofreu intervenção e serviu como controle. As demais raízes foram preparadas pelos instrumentos reciprocantes WaveOne (Dentsply-Maillefer) e Reciproc (VDW) e por um instrumento de rotação contínua One Shape (Micro-Mega). As raízes foram seccionadas horizontalmente com auxílio de uma máquina de corte de precisão (IsoMet 1000 Precision Saw) em 03, 06 e 09 mm a partir do ápice e observadas em um estereomicroscópio (Zeiss Stemi SV6, Carl Zeiss) sob um aumento de 20×. Imagens das fatias foram gravadas e avaliadas por dois observadores cegos, previamente calibrados. As fatias foram categorizadas em: 0 - Ausência de defeitos; 1- Outros defeitos; 2- Fratura Vertical da Raiz. Os resultados obtidos foram submetidos à análise estatística com nível de significância fixado em α= 0.05. Os testes Qui-quadrado e Exato de Fisher foram utilizados para analisar e comparar as diferenças entre os grupos. O grupo controle não apresentou defeito. Todos os grupos experimentais apresentaram defeitos dentinários e foram diferentes estatisticamente do grupo controle (P < 0.05). Os grupos reciprocantes foram associados à presença de mais defeitos do que o grupo One Shape, mas não houve diferença significante entre eles (P = .115). O grupo One Shape foi o único que apresentou FVR. Os resultados obtidos nesse estudo sugerem que o preparo biomecânico com instrumentos rotatórios e/ou de reciprocidade podem causar danos na dentina radicular.

Enquanto o segundo artigo realiza uma análise comparativa da segurança humana e da securitização à fim de demonstrar as diferenças e especificidades de ambos e procura demonstrar que apesar de existirem semelhanças entre os termos, e uma certa complementariedade, eles não são substituíveis. Já o terceiro aborda como e para quais interesses potências médias usam a segurança humana, através dos estudos de caso do Japão e Canadá a fim de demonstrar que estes beneficiam interesses próprios.The present thesis presents three papers that displays through the history of human security its comprehension from three points of view: history, concept and foreign policy tool. The first paper seeks to demonstrate that there is a low level of debate, dialogue and contribution between the development and security agenda in the construction of the human security approach through the Human Development Report (HDR) of the United Nations Development Program (UNDP) from 1994 and the International Commission on Intervention and State Sovereignty (ICISS) from 2001. While the second seeks to comparatively analyze human security and securitization to indicate differences and similarities and seeking to demonstrate that despite the similarities between the terms, and a certain complementarity, they are not replaceable. And lastly, the third one approaches how and to serve which interests middle powers use human security, through the case studies of Japan and Canada seeking to show rather they beneficiate self-interest.

Full textAbstract:
Thesis (MscAgric (Horticulture))--University of Stellenbosch, 2009.ENGLISH ABSTRACT: Experiments were conducted to increase the percentage class one ‘Granny Smith’ and ‘Cripps’ Pink’ apples. ‘Granny Smith’ is the most widely grown apple cultivar in South Africa, but its profitability is compromised by the high incidence of sunburn, red blush and poor green colour development. ‘Cripps’ Pink’ is a very lucrative cultivar and producers are striving to maximise the production of fruit that qualify for export. Fruit technologists and growers are debating whether it is best to maximise class one fruit in ‘Cripps’ Pink’ by increasing total yield or by increasing fruit quality. The relationship between ‘Granny Smith’ canopy position and external fruit quality was investigated. Light exposure, peel temperature, green colour development, sunburn and red blush development was followed for individual fruit from the outer, intermediate and inner canopy. Dark green fruit were exposed to moderate to high light levels (25-50% full sun) during the first half of fruit development, similar to fruit that eventually developed sunburn and red blush. The difference came in during the latter half of fruit development when dark green fruit became shaded (3% full sun). Pale green fruit contained less chlorophyll due to consistent low light levels (2% full sun). Fruit at partially shaded canopy positions had a lower occurrence of sunburn and red blush than outside fruit and better green colour development than fruit from the heavily shaded inner canopy. Based on these data, pruning strategies and mulching were evaluated to alter canopy vigour and the light environment in such a way that green colour development is promoted and the occurrence of sunburn and red blush is reduced. In an older, vigorous orchard with a dense canopy, pruning was done to increase light distribution for green colour development and to induce more growth on the side of the trees that are prone to sunburn and red blush. Pruning improved green colour development without affecting sunburn or red blush. In a younger, non-vigorous orchard, pruning and mulching were used to invigorate the canopy to increase shading of fruit and thereby decrease sunburn and red blush. However, these treatments were not effective. Further research should focus on the use of shade nets, accompanied by rigorous pruning, to reduce sunburn and red blush while not decreasing green colour. Five different crop loads were established in an exceptionally high yielding (averaging over 100 ton·ha1) ‘Cripps’ Pink’ orchard by first the thinning of clusters, then the removal of small fruit and, finally, the selective removal of fruit from the shaded inner canopy. Treatments had no effect on iv fruit quality in the first season. The most severe thinning treatment increased the percentage class one fruit in the second season by increasing the number of fruit with adequate red blush. However, seen cumulatively, the higher crop loads yielded more class one fruit per hectare than the lower crop loads, without affecting reproductive and vegetative development or fruit storability. Producers should strive for the highest crop loads allowed by the fruit size limitations in cultivars that are not prone to alternate bearing
AFRIKAANSE OPSOMMING: Eksperimente is uitgevoer om die persentasie uitvoerkwaliteit ‘Granny Smith’ en ‘Cripps Pink’ appels te verhoog. ‘Granny Smith’ maak die grootste deel uit van appel aanplantings in Suid Afrika, maar die winsgewendheid daarvan word beperk deur `n hoë voorkoms van sonbrand, rooi blos en swak groen kleurontwikkeling. ‘Cripps’ Pink’ is `n baie winsgewende kultivar en produsente streef daarna om die persentasie uitvoerkwaliteit vrugte te maksimaliseer. Vrugte tegnoloë en produsente debatteer oor die wenslikheid daarvan om uitvoerkwaliteit vrugte te maksimeer deur totale produksie te verhoog of deur vrugkwaliteit te verbeter. Die verband tussen ‘Granny Smith’ draposisie in die blaredak en eksterne vrugkwaliteit is ondersoek. Ligvlakke, skiltemperatuur, groen kleurontwikkeling, sonbrand en rooi blos ontwikkeling is deur die loop van die seisoen gevolg vir individuele vrugte aan die buitekant, binnekant en intermediêre posisies binne die blaredak. Daar is gevind dat die donkerste groen vrugte, nes vrugte wat uiteindelik sonbrand en rooi blos ontwikkel het, blootgestel was aan matige tot hoë ligvlakke (25-50% vol son) gedurende die eerste helfte van vrugontwikkeling. Donker groen vrugte is egter oorskadu (3% vol son) tydens die tweede helfte van vrugontwikkeling. Vanweë konstante lae beligting (2% vol son) het binne vrugte min chlorofiel geakkumuleer en daarom is hierdie vrugte lig van kleur. Vrugte in gedeeltelike skadu ontwikkel min sonbrand en rooi blos in vergelyking met buite vrugte en toon beter groen kleurontwikkeling as vrugte in diep skadu binne die boom. Gegrond op bogenoemde resultate is die gebruik van snoei strategieë en deklae om die groeikrag en die ligomgewing van die boom te modifiseer, ten einde groen kleur ontwikkeling te bevorder en sonbrand en rooi blos te verminder, geëvalueer. In ‘n ouer, groeikragtige boord met ‘n digte blaredak is snoei gebruik om ligverspreiding te verbeter vir groen ontwikkeling en om meer groei te stimuleer aan die buitekant van die boom wat meer geneig is tot sonbrand en rooiblos. Groen kleur is wel verbeter, maar sonbrand en rooi blos is nie geaffekteer nie. In `n jonger, minder groeikragtige boord is ‘n deklaag aangebring en eenjarige lote getop, sodoende groei te stimuleer om sonbrand en rooi blos te verminder deur oorskaduwing van vrugte. Hierdie behandelings was egter nie effektief nie. Toekomstige navorsing moet fokus op die gebruik van skadunette tesame met ‘n nougesette snoei strategie om sonbrand en rooi blos te verminder sonder om groen kleur te verswak. Vyf verskillende vrugladings is geskep in `n uitermatig produktiewe (gemiddeld meer as 100 ton·ha-1) ‘Cripps’ Pink’ boord deur eers vrugtrosse uit te dun, gevolg deur die verwydering van klein vrugte en, laastens, die selektiewe verwydering van vrugte in die diep skaduwee van die binneste blaredak. Vrugkwaliteit is nie in die eerste seisoen nie deur oeslading geaffekteer nie. Die strafste uitdunbehandeling het wel die persentasie uitvoerbare vrugte in die tweede seisoen verhoog deur die aantal vrugte met voldoende rooi blos te vermeerder. Kumulatief gesien, het die hoër oesladings egter meer klas een vrugte per hektaar opgelewer sonder om die reproduktiewe en vegetatiewe ontwikkeling of die stoorvermoë van vrugte te affekteer. Produsente moet strewe na die hoogste oesladings wat toegelaat word deur vruggrootte beperkings in kultivars wat nie geneig is tot alternerende drag nie

Full textAbstract:
Dans cette thèse, nous présenterons une architecture de communication multi-utilisateurs à base des réseaux de capteurs sans fil dans un environnement industriel fortement bruité. Deux modes de fonctionnement de cette architecture sont présentés ; un mode Many-To-One reliant plusieurs capteurs émetteurs à un seul récepteur et un mode One-To-Many reliant un émetteur à plusieurs capteurs récepteurs. La couche physique de ce système est basée sur une modulation par transformée par paquets d'ondelettes inverse (IDWPT) à l'émission et une transformée par paquets d'ondelette discrète (DWPT) en réception. Pour tester notre architecture, un modèle de canal industriel est proposé qui tient compte des phénomènes des multi-trajets et des évanouissements en plus du bruit additif. Ce dernier étant modélisé comme un bruit gaussien auquel s'additionne un bruit impulsionnel causant une dégradation significative des signaux. L'architecture est testée pour différentes configurations de communications sans fil et pour différentes formes d'ondelettes afin de proposer un mode de communication optimal. Aussi, une amélioration de la robustesse de notre système est effectuée en ajoutant un codage correcteur d'erreur du canal et un seuillage du bruit impulsionnel à la réception pour minimiser les effets du bruit industriel sur les signaux reçus. En utilisant un code correcteur d'erreur, la détection et reconstitution des signaux se fait sans erreur à partir d'un SNR de 8dB pour un taux de codage 1/4 pour une transmission sur à canal à évanouissement. Pour un récepteur optimal à base du seuillage du bruit, les performances en termes de taux d'erreur binaires sont améliorées de 10dB pour une transmission sur un canal à bruit industriel. Enfin, une comparaison de la robustesse de notre architecture impulsionnelle avec un système à base d'une modulation multi-porteuse classique OFDM est effectuée. Ceci nous amène à proposer un système de communication multi-utilisateurs robuste à base des réseaux de capteurs sans fil pour des communications en milieu industriel difficileIn this thesis, we will present a multi-user communication architecture based on wireless sensor networks in a noisy industrial environment. Two modes of operation of this architecture are presented ; a Many-To-One mode linking several transmitter sensors to a single receiver and a One-To-Many mode linking a transmitter to several receiver sensors. The physical layer of this system is based on the inverse transform (IDWPT) at transmission and the discrete wavelet packet transform (DWPT) at reception. To test our architecture, an industrial channel model is proposed that takes into account the phenomena of multipath and fading in addition to additive noise. The latter being modelled as Gaussian noise to which is added an impulse noise causing significant signal degradation. The architecture is tested for different wireless communication configurations and wavelet shapes to provide an optimal communication mode. Also, an improvement in the robustness of our system is achieved by adding channel error correction coding and pulse noise thresholding at reception to minimize the effects of industrial noise on the received signals. Using an error-correcting code, the detection and reconstruction of signals is error-free from an SNR of 8dB for a coding rate of 1/4 for transmission on a fading channel. For an optimal receiver based on noise thresholding, the performance in terms of binary error rates is improved by 10dB for transmission over an industrial noise channel. Finally, a comparison of the robustness of our pulse architecture with a system based on a conventional OFDM multi-carrier modulation is carried out. This leads us to propose a robust multi-user communication system based on wireless sensor networks for communications in difficult industrial environments

The present work consists of a hybrid numerical-analytical simulation of the developing and fully developed turbulent flows inside a parallel-plates channel. The Reynolds equations for the mean flow are solved through the Generalized Integral Transform Technique (GITT) in the boundary layer and streamfunction-only formulations. For turbulence closure, the respectively one-equation turbulence models, and some of their variations, developed by Secundov (1972), Baldwin e Barth (1990), Spalart e Allmaras (1992, 1994) and Menter (1997) were employed. Despite of based on the eddy viscosity concept, as the well-known one-equation k-L turbulence model previously adopted in works that made use of the present hybrid solution methodology, such models do not need any explicit length scale, and therefore are more generals, but only one transport equation for the turbulent viscosity or for a variable directly related to the eddy viscosity. In this sense, some simulations for different Reynolds numbers and different turbulent inlet conditions were developed in order to, in function of the obtained results and the convergence studies of the main potentials involved in the simulations, develop a critically and detailed discussion of the main shortcomings and capability predictions of each turbulence model adopted, such as the non-asymptotic development of the longitudinal velocity component and the friction factor fields. As a consequence of the analysis type performed over each turbulence model investigated and, in addition, due to the excellent numerical quality of the obtained results, the present work extends and consolidates the very important role that the integral transform technique may play in the computational fluid dynamics field meanwhile hybrid methodology.
O presente trabalho consiste na simulação numérico-analítica do escoamento turbulento isotérmico, em desenvolvimento e completamente desenvolvido, no interior de um canal de placas planas e paralelas, através da Técnica da Transformada Integral Generalizada (GITT). As equações médias de Reynolds, escritas segundo as hipótese de camada limite são empregadas na formulação de função corrente. Para o fechamento das equações médias da turbulência foram empregados os modelos de turbulência de uma equação de transporte (e algumas de suas variações) desenvolvidos pelos seguintes autores: Secundov (1972), Baldwin e Barth (1990), Spalart e Allmaras (1992, 1994) e Menter (1997). Apesar de baseados no conceito de viscosidade turbilhonar ( eddy viscosity ), como o tradicional modelo de turbulência de uma equação k-L, anteriormente empregado em trabalhos que fizeram uso da presente metodologia híbrida de solução, tais modelos não necessitam de uma escala explícita de comprimento, e por isso são ditos mais gerais, mas sim, de apenas uma equação de transporte para a própria viscosidade turbulenta (ou uma variável diretamente relacionada à própria viscosidade turbulenta). Nesse sentido, foram simuladas algumas situações de escoamentos (diferentes números de Reynolds e diferentes condições de entrada turbulenta) e buscou-se, em função dos resultados obtidos e de estudos de convergência dos principais potenciais envolvidos nas simulações, uma criteriosa e detalhada discussão das capacidades de previsão de certas características inerentes ao escoamento (o pico da componente longitudinal da velocidade no centro do canal e a depressão do fator de atrito, durante o desenvolvimento do escoamento, ou seja, o comportamento não assintótico dessas variáveis no escoamento) por todos os modelos de turbulência empregados. Em função do tipo de análise oferecida sobre cada modelo de turbulência utilizado, e, em adição, da excelente qualidade dos resultados obtidos com o uso da GITT, o presente trabalho extende e consolida o importante papel que a técnica da transformada integral pode desempenhar no campo da simulação computacional, enquanto metodologia híbrida.

Full textAbstract:
This dissertation analyzes seventeenth- and eighteenth-century French perceptions of the bodies of Indians in New France and Louisiana. It reveals that all French authors who visited New France in the early seventeenth century believed that human differences were mutable and, with instruction and land cultivation, Indians would physically and culturally assimilate into French colonial society---if Europeans did not degenerate from life in the wilderness first. Beginning in the late seventeenth century, missionary disillusionment, colonial projections of order and later Enlightenment concepts of natural rights and systems of nature prompted authors to reformulate these early perceptions. As Indians appeared unwilling or unable to adopt civilized manners, some authors concluded that natives did not possess the reason needed to do so. By the late eighteenth century, some colonial officials and European naturalists suggested that the physique and morals of North American Indians were not mutable but, instead, that Indians in French North America were permanently and essentially incapable of "improving" either their bodies or their minds.Historians studying seventeenth- and eighteenth-century colonial perceptions of North American Indians have generally analyzed European depictions of Indians with twentieth-century understandings of human difference. By examining French perceptions of Indians with early modern understandings of the body, this thesis seeks to see natives through the eyes of the authors who described them.
The sources for this study include French travelogues and missionary accounts from New France and Louisiana which were published contemporaneously, correspondence and memoirs which have since been published and archived letters from colonial administrators writing from Canada and Louisiana.

Financed by a wealthy Montreal businessman, the original regiment was very British in its make-up. The Patricia’s were recruited and trained separate from the Canadian Expeditionary Force. For the first year of the war, they fought in a British brigade, under British officers using British weapons. By 1919, the PPCLI were distinctly Canadian. The Patricia’s became the best known Canadian regiment and one of three retained in the permanent force. This thesis examines that remarkable transition, the changes wrought by the war and the mechanisms used to reinforce the unique image of the Patricia’s. It also tests several myths embodied in the histories of the Regiment against a database of over five thousand files of soldiers who served with the Patricia’s during the First World War.Graduate

Full textAbstract:
The understanding of the dynamics of the climatic variables is critical to model and predict climatic and environmental changes. Traditional measures collected by the meteorological stations network are dispersedly located throughout the territory in the northern high latitudes and errors associated to these variations can be considerable. Our goal is to evaluate the contribution of the remote sensing by passive microwaves compared to the ground measurements for better characterizing the variations in the surface temperature during the winter. In the presence of snow, extraction of the surface parameters by microwave measurements is a complex and ill-conditioned problem. We evaluated a semi-empirical relation based on a theoretical analysis to estimate the surface temperatures with the measured brightness temperatures at 19 and 37 GHz (vertical polarization). Simulations of emissivity made with the Helsinki Technology University (HUT) model, the knowledge of the land cover, and the forest biomass enable us to define this relationship.The results of the comparison between the calculated surface temperatures and the air temperatures for the entire Canada (137 stations) and for two winters, 1992-93 and 2002-03 (16359 measurements) show a significant correlation with an estimation error ranging between 4 and 7[degrees Celsius] according to the regions considered. These results are discussed according to region and type of land cover (grassland, forest, tundra).

Full textAbstract:
In public education, it is not possible to present school programs that will satisfy all the external groups from society. When an outside interest group perceives a need that is lacking in the schools' curriculum, it may petition the ministry of education or the local school board to include its need into the curricula. Another method to influence or insert its point of view is for the interest group to produce its own curriculum for a school program. This study investigated the impact of one outside interest group as it attempts to modify students' attitudes through its school program, Salmonids in the Classroom. Werner's description of editorial criticism permitted examination with a political perspective, of the resource package, Salmonids in the Classroom. The methodology of this analysis permitted a view of the goals and values espoused and hidden in a school program and how those goals and values were modified as they are passed from the program sponsors through the developers to the teachers. To determine the effects of the Salmonids in the Classroom Program upon student attitudes toward the salmonid resource, a Likert-type instrument using a slide show was used. To understand children's beliefs and attitudes about the salmonid resource, student interviews were conducted with some students after they were exposed to the Salmonids in the Classroom Program. This study confirms that a special interest group can sponsor a school program and modify student attitudes to be more supportive of the interest group's programs and goals. This study may be useful not only to teachers to assist in clarifying their role with the special interest group's school program, but it may also be useful to special interest groups who may be planning ways to influence the public through the school system.Education, Faculty of

Full textAbstract:
De tous les canaux ioniques, les canaux K+ forment une classe où la diversité structurale et fonctionnelle est certainement la plus importante. Ils interviennent dans un nombre considérable de processus physiologiques. Les canaux K+ sont répartis en trois familles selon leurs propriétés structurales et fonctionnelles, et 67 gènes sont connus à ce jour. Les caractéristiques de la plupart de ces canaux sont bien établies in vitro, mais leur rôle physiologique n'est pas toujours connu. L'invalidation de gènes chez la souris est un outil qui peut permettre de déterminer le rôle d'un gène donné in vitro. Nous avons utlisé cette technique pour étudier la fonction des sous-unités KCNE1 et TWIK1. Les souris kcne1 -/- ont dèjà permis de comprendre la fonction des courants Iks dans l'oreille interne. Ces souris présentent en effet une surdité identique à celle des patients atteints du syndrome de Jervell et Lange-Nielsen. Des mutations de gènes humains kcne1 et kcnq1 ont été associées à ce syndrome cardio-auditif. L'étude de la fonction cardiaque des souris kcne1 -/- a révélé que l'intervalle QT de l'électrocardiogramme n'est pas très différent de celui des souris sauvages. Par contre, la sous-unité KCNE1 permet l'adaptation de l'intervalle QT en fonction des battements du coeur. D'autre part, les souris kcne1 -/- présentent une légère hypokaliémie associée à un hyperaldostéronisme (. . . ). La seconde partie de ce travail concerne l'étude de la sous-unité TWIK1. Ce canal est fortement exprimé dans le système nerveux central et dans de nombreux tissus épithéliaux.

Full textAbstract:
Cette thèse aborde quelques aspects des interactions herbivores-plantes chez le canard siffleur Anas penelope, la bernache nonnette Branta leucopsis et l'oie cendrée Anser anser. Dans un premier temps, cette étude souligne les contraintes alimentaires liées à certaines propriétés des plantes à travers l'exemple du siffleur qui ne peut ingérer assez de salicorne (Salicornia ramosissima) pour assurer ses besoins énergétiques, à cause de contraintes physiologiques/digestives. Dans un deuxième temps, l'étude des choix des sites d'alimentation du siffleur et de l'oie cendrée sur la réserve naturelle de Moe͏̈ze (Charente-Maritime) montre que les siffleurs préfèrent s'alimenter sur les prairies à équins où l'herbe est rase, alors que les oies cendrées préfèrent brouter une herbe plus haute, générée par un pâturage bovin. Afin de comprendre les préférences de hauteur d'herbe chez ces deux espèces, des expérimentations en élevage ont été effectuées, en incluant une troisième espèce, la bernache nonnette. L'établissement de la réponse fonctionnelle de ces trois espèces montre des différences interspécifiques : l'ingestion est régulée par des processus complexes influencés par la hauteur de l'herbe, la morphologie du bec de l'espèce et ses besoins nutritionnels. Certains mécanismes diffèrent de ceux des mammifères, notamment pour ce qui est du rôle du temps de prélèvement des bouchées d'herbe qui limite la vitesse d'ingestion. Des expériences de choix de " patches " ont montré que ces trois espèces préfèrent une hauteur d'herbe qui leur permet de maximiser leur vitesse d'ingestion de nutriments. L'importance relative de la quantité et de la qualité de l'herbe sur les choix des sites d'alimentation semble varier selon des contraintes digestives et métaboliques liées à la taille des espèces. Les résultats de cette thèse permettent de faire des suggestions pour gérer la hauteur et la qualité de l'herbe des prairies humides, afin de fournir aux Anatidés herbivores en hivernage des zones d'alimentation favorables.

Full textAbstract:
Lorsqu'un phénomène de détonation survient dans des milieux confinés comme un bâtiment présentant un système de galeries, l'onde de choc générée se propage et peut engendrer des dégâts matériels et humains considérables. En effet, l’onde de choc en se propageant dans ces systèmes de canaux confinés va interagir avec les obstacles qu’elle rencontre (humains et matériels), et va provoquer de très fortes élévations de la pression localement. Ce phénomène peut être très destructeur pour les structures et létale pour les humains. L'objectif de cette étude, expérimentale et numérique, est donc d'étudier la propagation d'une onde de choc dans différents systèmes de canaux afin de comprendre son comportement et de proposer des solutions pour en atténuer les dégâts. L’étude s’articule autour de deux grands axes. Le premier étudie de manière très académique la propagation d’une onde de choc au travers de cinq configurations différentes ; deux sans variation de section (un coude à 45$^{\circ}$ et un coude à 90$^{\circ}$), et trois avec variation de section (un divergent, un élargissement brusque et une bifurcation en « Y »). L’influence de la singularité sur la pression réfléchie en fond de configuration est étudiée ainsi que les mécanismes physiques complexes qui se produisent derrière l’onde de choc le long de la singularité. Le deuxième axe étudie l’atténuation de la pression réfléchie par l’ajout de piège (cavités) le long du système étudié. Une étude paramétrique montre que la position ainsi que la taille et la forme du piège ont un impact sur l’atténuation de l’onde de chocIn the search for protection from explosions phenomena, a variety of underground shelters were studied to minimize the risks related to the propagation of shock waves in closed areas. Indeed, the blast effect could be really destructive for equipment and humans encountering the shock wave propagation, because of the high elevation of the local pressure it generates. Thus, the propagation of a shock wave through various canal systems is both experimentally and numerically studied. This study is based on two topics. The first part is focused on the study of the propagation of a shock wave through five various configurations ; two whithout aera change (a 45$^{\circ}$ bend duct and a 90$^{\circ}$ bend), and three configurations whith a sectional enlargement (a divergent, an abrupt area change and a « Y » bifurcation). The impact of the geometry on the end wall reflected pressure is studied as well as some complex physical mechanisms that occur behind the incident shock wave. The second part explores the mitigation of the pressure level in the device with the addition of traps (cavities) along the studied configuration. A parametric study based on the shape and size of the cavities, shows that these parameters have a considerable impact on the pressure level in the duct system

L'apparition de nouveaux services nécessitant de comminiquer à des débits de plus en plus élevés et avec une qualité meilleure est à I'origine de l'émergence de la troisième génération de radio-mobiles. En Europe. Ies caractéristiques de cette nouvelle génération sont entrain d'être spécifiées dans la norme UMTS ("Universal Mobile Télécommunication Standard"). Dans ce mémoire de thèse, nous avons traité divers thèmes clés de la norme UMTS. Nous avons commencé par développer les structures de deux implémentations du récepteur en râteau permettant de récupérer une grande partie de la diversité offerte par le canal multitrajets. Le premier récepteur est celui qu'on utilise d'habitude et consiste à combiner les sorties de corrélateurs synchronisés sur les trajets les plus significatifs. Afin de contourner le problème d'estimation des délais des trajets nous avons étudié également une implémentation à temps discret du récepteur en râteau. Cette approche est basée sur une estimation globale du produit de convolution des réponses impulsionnelles du canal de propagation et du filtre de mise en forme. Ensuite, nous avons traité les problèmes engendrés par l'interférence entre symboles qui apparaîssent pour des services à haut débit. Ce thème est d'une importance primordiale pour l'UMTS dont le pari est justement de pOUVOir assurer de tels services. Après cela, nous avons étudié puis optimisé la procédule de contrôle de puissance qui permet de lutter contre l'effet des épanouissements. Enfin. Nous avons recherché la meilleure stratégie d'allocation de l'énergie du canal RACH ("Random Access Channel") afin de réduire l'intertérence qu'il génère.

Évaluer la capacité de remplissage des cinq différentes techniques d’obturation canalaire dans l’obturation des canaux ovales. Matériel et méthodes : Un total de 220 molaires mandibulaires, avec 1 canal dans la racine distale, a été sélectionné. Chaque canal a été mise en forme jusqu’à la longueur de travail en utilisant un système mono-instrument le WaveOne Gold Primary Les dents préparées ont été divisées au hasard en cinq groupes égaux (n = 40 par groupe) pour l'obturation: condensation à onde continue (CWC), technique avec tuteur GuttaCore (GC), technique avec tuteur Thermafil (TH), technique utilisant un cône unique (SC), condensation hydraulique à froid (CHC). Les pourcentages de GPFA, SFA et VA ainsi que la présence des matériaux d’obturation à l’intérieur des tubulis dentinaires (tag)à longueur de travail (LT) -4mm et -2 mm a été évalué à par microscopie numérique optique, microscopie électronique à balayage (SEM) et microanalyse par rayons X à dispersion d'énergie (EDX). Analyse statistique : Les données collectées ont été analysées avec la version 11.2 de SigmaPlot (Systat Software, Inc., San José, CA, USA). Les pourcentages de GPFA, SFA, VA correspondant aux différentes groupes ont été comparés en utilisant le test de Kruskal-Wallis avec α=0,05. Résultats: à LT-4 et LT-2 mm, cette étude à montré une différence statistiquement significative en terme de capacité d’obturation pour le cinq techniques. À LT-4, les groupes GC et TH ont montré une différence statistiquement significative par rapport aux trois autres groupes en terme de GPFA et SFA. En terme de VA, il y a une différence statistiquement significative avec les groupes SC et CHC tandis qu’aucune différence n’a été démontrée entre les groupes GC , TH et CWC . À LT-2, les groupes GC et TH ont montré une différence statistiquement significative par rapport aux trois autres groupes en terme de GPFA, SFA, VA. Conclusion : Cette étude montre clairement que les obturations par GC et TH sont en mesure de remplir les canaux ovales d’une manière plus appropriée que les autres techniques d’obturation. Les groupes GC et TH, à LT -4 et -2mm, présentaient des tags de gutta-percha à l’intérieur des tubulis dentinaires. La présence de tags de gutta-percha à l’intérieur des tubulis dentinaires (à la place de tags de ciment beaucoup plus vulnérables) pourrait se comporter comme une barrière physique, capable de sceller les bactéries à l’intérieur des tubulis et surtout non résorbable dans le tempsAssess the filling ability in oval-shaped canals using five different filling techniques. Materials and Methods : 220 human mandibular first molars with one distal oval canal were selected. Distal Canals were shaped using WaveOne Gold Primary. The prepared teeth were randomly divided in four equal groups (n = 40) for obturation : Continuous Wave Condensation (CWC), GuttaCore carrier based technique (GC), Thermafil (TH) carrier based technique, Single Cone technique (SC), Cold hydraulic Condensation (CHC). The proportions of gutta-percha filled areas (GPFA), sealer filled areas (SFA), void areas (VA) and the tags into dentinal tubules at 4 mm and 2 mm were analyzed by Optical numeric microscope, SEM and EDX. Statistical analysis : they were compared by Kruskal-Wallis one-way ANOVA on ranks, with statistical significance set at α = 0.05. Results : At 4 and 2 mm from the apex, this study discloses statistically different filling ability for the five techniques. At 4 mm from the apex, the GC et TH groups showed significantly higher PGFAs than lateral condensation and System B techniques. The GC et TH groups showed a statistically significance difference compared with the others three groups in terms of higher PGFA, lower SFA. It showed a statistically significance difference with SC and CHC groups in term of VA. At 2 mm level from the apex, the GC et TH groups showed a statistically significance differece compared with the others three groups in terms of higher PGFA, lower SFA and VA. Conclusions : GC obturation is able to fill oval-shaped canals in a more appropriate way than the other filling techniques. GC was the only group which showed the presence of gutta-tags at 4 and 2 mm from the apex. The gutta- percha tags could behave as a physical barrier able to entomb bacteria

Through extensive sediment sampling and numerical analysis, it was found that particulate carbon was the best predictor of potential for anaerobic production of CH$ sb4$ and CO$ sb2$. The only predictor of denitrification capacity was anaerobic CO$ sb2$ production, indicating that beside NO$ sb3 sp-$ and O$ sb2$, a biotic factor involved in carbon metabolism may be important in the control of this activity.Suppression of aerobic N$ sb2$O production in sediment slurries by C$ rm sb2H sb2$ and correlation with NO$ sb3$-production indicated that it was dependent on chemolithotrophic nitrification. Although CH$ sb4$ (1 to 24 $ mu$M) stimulated production of NO$ sb3 sp-$ and N$ sb2$O, we found that CH$ sb4$ at 84 $ mu$M or greater suppressed nitrification. Following extensive studies of pore water chemistry, potential microbial activities, and counts of nitrifiers and methanotrophs, we found that CH$ sb4$ oxidation (i) is more likely to suppress nitrification by competition for O$ sb2$ and NH$ sb4 sp+$ between methanotrophs and nitrifiers, and (ii) may be more important than nitrification as a sink of hypolimnetic O$ sb2$ in Hamilton Harbour.
Amongst a number of inhibitors, allylsulfide was found to be a differential inhibitor with much less effect on CH$ sb4$ oxidation in sediment slurries or in axenic cultures of Methylosinus trichosporium OB3b than on nitrification in sediment slurries.

Cancer represents a major cause of human morbidity and mortality. There is no scientific consensus regarding cancer causality or prevention. Occupational exposure potentially remains a major contributor to the incidence of this group of diseases, but the data to assess its impact continues to elude researchers and public health advocates. Among women in industrialised countries, breast cancer is the most prevalent cancer. The known or suspected risk factors, including family history and lifetime oestrogen load, can account for less than 50 percent of the cases. New hypotheses about the role of xenoestrogens and endocrine disrupting compounds are challenging the previous scientific precepts regarding cancer causality. Within this context, the extent to which a community-based occupational history data collection initiative can contribute to advancing our scientific understanding of associations between cancer and work is explored. The possibility that occupational histories data can find associations missed in conventional breast cancer research that ignore occupation is also explored. More specifically, the extent to which data derived from an occupational history questionnaire can provide insight into the potential association between breast cancer risk and farming is examined. Occupational histories of cancer patients contain data that could help to elucidate and inform our understanding of cancer aetiology and prevention. In the community of Windsor, Ontario, Canada a local cancer treatment centre responded to community concerns by cooperating in a collaborative research project to collect the occupational histories of cancer patients. 'Computerised Record of Occupation Made Easy' (CROME) was an innovative method that allowed individual patients to document their lifetime work histories. This data collection process represented the first time a local Canadian cancer treatment center had undertaken such an initiative. Based on the hypothesis generated by CROME, a new research study was launched - Lifetime Occupational History Record (LOHR). Over a two-and-a-half year period, all female patients at the Windsor Regional Cancer Centre with new incident breast cancer were invited to participate in a population-based case-control study along with an equivalent number of randomly selected community controls. A comprehensive lifetime history questionnaire was administered to subjects by interview. Data gathered included known or suspected risk factors along with a complete occupational history of all jobs ever worked. An occupational history of farming alone produced an Odds Ratio (OR) = 2.8 (Cl, 95%, 1.6-4.8). These findings are important for our understanding of cancer causality with implications for resolving the current scientific conflict regarding the role of occupationally caused carcinogenesis. Such collaborative, community-based studies also demonstrate the importance of community participation in the scientific research process.

Full textAbstract:
La région de l'archipel canadien, située en Arctique, connaît actuellement d'importants changements climatiques, se traduisant notamment par une augmentation des températures, une réduction de l'étendue de la banquise marine et du couvert nival terrestre ou encore une perte de masse significative des calottes glaciaires disséminées sur les îles de l'archipel. Parmi ces calottes glaciaires, la calotte Barnes, située en Terre de Baffin, ne fait pas exception comme le montrent les observations satellitaires qui témoignent d'une importante perte de masse ainsi que d'une régression de ses marges, sur les dernières décennies. Bien que les calottes glaciaires de l'archipel canadien ne représentent que quelques dizaines de centimètres d'élévation potentielle du niveau des mers, leur perte de masse est une composante non négligeable de l'augmentation actuelle du niveau des mers. Les projections climatiques laissent à penser que cette contribution pourrait rester significative dans les décennies à venir. Cependant, afin d'estimer les évolutions futures de ces calottes glaciaires et leur impact sur le climat ou le niveau des mers, ils est nécessaire de caractériser les processus physiques tels que les modifications du bilan de masse de surface. Cette connaissance est actuellement très limitée du fait notamment du sous-échantillonnage des régions arctiques en terme de stations météorologiques permanentes. Une autre particularité de certaines calottes de l'archipel canadien, et de la calotte Barnes en particulier, est de présenter un processus d'accumulation de type glace surimposée, ce phénomène étant à prendre en compte dans l'étude des processus de surface. Pour palier au manque de données, l'approche retenue a été d'utiliser des données de télédétection, qui offrent l'avantage d'une couverture spatiale globale ainsi qu'une bonne répétitivité temporelle. En particulier les données acquises dans le domaine des micro-ondes passives est d'un grand intérêt pour l'étude de surfaces enneigées. En complément de ces données, la modélisation du manteau neigeux, tant d'un point de vue des processus physiques que de l'émission électromagnétique permet d'avoir accès à une compréhension fine des processus de surface tels que l'accumulation de la neige, la fonte, les transferts d'énergie et de matière à la surface, etc. Ces différents termes sont regroupés sous la notion de bilan de masse de surface. L'ensemble du travail présenté dans ce manuscrit a donc consisté à développer des outils permettant d'améliorer la connaissance des processus de surface des calottes glaciaires du type de celles que l'on rencontre dans l'archipel canadien, l'ensemble du développement méthodologique ayant été réalisé sur la calotte Barnes à l'aide du schéma de surface SURFEX-CROCUS pour la modélisation physique et du modèle DMRT-ML pour la partie électromagnétique. Les résultats ont tout d'abord permis de mettre en évidence une augmentation significative de la durée de fonte de surface sur la calotte Barnes (augmentation de plus de 30% sur la période 1979-2010), mais aussi sur la calotte Penny, elle aussi située en Terre de Baffin et qui présente la même tendance (augmentation de l'ordre de 50% sur la même période). Ensuite, l'application d'une chaîne de modélisation physique contrainte par diverses données de télédétection a permis de modéliser de manière réaliste le bilan de masse de surface de la dernière décennie, qui est de +6,8 cm/an en moyenne sur la zone sommitale de la calotte, qui est une zone d'accumulation. Enfin, des tests de sensibilité climatique sur ce bilan de masse ont permis de mettre en évidence un seuil à partir duquel cette calotte voit disparaître sa zone d'accumulation. Les modélisations effectuées suggèrent que ce seuil a de fortes chances d'être atteint très prochainement, pour une augmentation de température moyenne inférieure à 1°C, ce qui aurait pour conséquence une accélération de la perte de masse de la calotte.

Full textAbstract:
There is a popular misconception in the world that Jehovah is too severe on occasion while Jesus Christ is always kind and merciful. The Latter-day Saint belief that Jehovah and Jesus are the same person presents a supposed conflict. There has not been much written on this subject by either non-Latter-day Saints or Latter-day Saints, thus, this thesis represents a unique contribution to a common perception prevalent in many Christian circles. The research of this thesis shows that the misconception is based on three problems: first, a misinterpretation of biblical stories in both the Old and New Testament; second, a lack of understanding biblical context and culture; and third, a lack of applying modern revelation to this subject. The research of this thesis focuses on these three areas in an effort to resolve this false perception. This thesis takes a deeper look into the acts of Jehovah and Jesus Christ as found in the Old and New Testaments respectively. Next, it looks as several doctrines related to this subject that have been revealed through latter-day prophets and incorporates them into the Old Testament. This analysis paints a broader picture of the Lord and illustrates that He was, indeed, merciful in the Old Testament but, at times, severe in the New Testament. Lastly, this thesis takes four of the most difficult Old Testament stories that seem to represent Jehovah as harsh, capricious, and unyielding, and puts them in their cultural setting. Though not every act can be completely explained, there is a high degree of similarity between Jehovah and Jesus. The study concludes, therefore, that much of the problem lies with perception and not with reality.
