Ce travail expérimental concerne l'analyse du transfert de chaleur au sem d'un écoulementturbulent d'air humide en présence ou non d'un phénomène de condensation. Pour cela, une souffleriespécifique a été conçue au sein du laboratoire afi n de générer un écoulement d'air contrôlé en vitesse,en température et en teneur en humidité. Cet écoulement traverse un canal d'étude rectangulairehorizontal dont les parois inférieures sont maintenues à température constante. Une première partie destravaux permet de décrire l'écoulement au se in du canal par l'analyse des champs de vitesse PlVmoyenne et fluctuante pour différents nombres de Reynolds (Re = 10056 à Re = 55333) et dedétailler les régimes dynamiques obtenus. Dans la zone pleinement turbulente, une attentionparticulière a été portée sur la caractérisation de la sous-couche visqueuse par PlV à haute résolutionspatiale. L'analyse fine du profil de température d'air en proche paroi permet d'estimer avec précisionle transfert convectif local. Les résultats obtenus sans changement de phase ne montrent pasd'influence de la teneur en humidité sur le flux convectif. Au-delà des résu ltats en milieu non-saturé,le phénomène de condensation est abordé. La visualisation du dépôt de vapeur d'eau condenséepermet d' identifier macroscopiquement les différents régimes de condensation (film, gouttes oumixte). L' analyse fine à échelle locale permet de définir différentes étapes de la condensation:développement par grossissement et par fusion entre plusieurs gouttes, mouvements de frontièresaprès fusion. Cette étude a été menée pour des substrats de nature et de conditions de mouillabilitédifférentes, ainsi que pour des taux d'humidité absolue variables. Enfin, l' identification de ces étapesest complétée par la quantification de la condensation à partir des mesures de masse condensée.Celles-ci sont exploitées pour estimer les flux de chaleur latente et pour comparer le comportement surdifférents substrats. / Heat transfer in a turbulent moist airflow field is under investigation with or without condensation phenomena. A dedicated experimental set-up was developed and with special attention was given to the control of mass flow rate, temperature and moisture content at inlet. Flow field then develops within a rectangular channel with thermal regulation at walls. Characteristic Reynolds number range studied is between 10 056 and 53 333 and average and fluctuating dynamic and thermal fields were depicted by PIV and thermocouple investigation respectively. In the turbulent region, a refined analysis was carried to characterize the sub-layer viscous region (from high-resolution PIV measurements) and temperature profiles at the very close vicinity of the wall allows one to locally estimate convective heat flux. Results underline that the degree of moisture of unsaturated humid air does not play any major role on the thermal flux exchanged. Beyond the saturation regime, condensation occurs and water vapor deposited along the flat horizontal wall is analyzed. Condensation is driven by several regimes (film-wise, dropwise and mixed) and within drop-wise condensation, size distribution as well as drop coalescence is detailed. Our analyses was carried on three substrates presenting different wettability conditions while moisture degree was considered as an additional parameter. Finally, the mass of condensed water was measured in time and latent heattransfer was estimated and compared between the different substrates.

The Farmers' Alliance in Wise County, from its introduction in 1880 to its demise in 1897, endeavored to improve the mental, moral, social, and financial conditions of small agrarians in the north central Texas county. This paper details the Alliance's efforts, in cooperative ventures and political activism and third-party politics, to place farmers in a better economic position. Additionally, the paper focuses on the Alliance's attempts to provide educational and social opportunities and moral guidance to the membership. Source materials include government documents and publications, contemporary accounts, the county Alliance's official newspaper, area newspapers, and the original minutes of the county Alliance from 1893 to 1897.

Master of Science / Department of Statistics / Paul I. Nelson / A Bonferroni and an ordered P-value solution to the problem of controlling the experiment-wise Type I error rate are studied and compared in terms of actual size and power when carrying out correlated tests. Although both of these solutions can be used in a wide variety of settings, here they are only investigated in the context of multiple testing that specified pairwise comparisons of means, selected before data are collected, are all equal to zero in a completely randomized, balanced, one factor design where the data are independent random samples from normal distributions all having the same variance. Simulations indicate that both methods are very similar and effective in controlling experiment wise type error at a nominal rate of 0.05. Because the ordered P-value method has, almost uniformly, slightly greater power, it is my recommendation for use in the setting of this report.

An analysis utilizing both ArcGIS and ethnographic interviews from private land owners and environmental professionals examined how man-made landscape changes affected plant and tree species in the LBJ National Grasslands in Wise County, Texas north of Decatur. From the late 1800s to the Dust Bowl Era the land was used for crop production and cattle grazing resulting in erosion and loss of soil nutrients. The research indicated by 2001 that cattle grazing and population increase resulted in land disturbance within the administrative boundary of the national grasslands. Participants expressed concern over the population increase and expansion of 5 to 10 acre ranchettes for cattle grazing common in modern times. Recommendations for the future included utilizing and expanding the resources already existing with environmental professionals to continue controlling erosion.

Companies in industries around the world are in a race that gets more difficult every year, with bigger, stronger, and more innovative competitors. In addition, the rules of the race are constantly changing with the emergence of electronic business, globalization, disruptive technologies, innovation and convergence of industries. Competitors who have been in other races suddenly join your race with strength, technology, and new approaches to the market - often becoming instant leaders . Leaders are successfully developing new core competencies that enable them to be highly competitive and valuable today and that bodes well for their longer-term future. Strategy managers , constantly try to improve the productivity of their systems .A firm that can improve the input - output relationship normally increase profitability. Competitive position, one measure of corporate success is a relative dominance in the market place . Firms commonly establish objectives in terms of their competitive positions . / Thesis (MBA)-University of Natal, 2003.

Research on consumer perceptions towards dairy animal welfare is lacking in Canada. Though consumers are aware of animal welfare issues in other animal industries, the dairy industry remains largely ignored. This thesis employed a mail survey in order to discover the opinions of Canadians towards dairy animal welfare. Respondents answered questions about the importance of animal welfare and its relative importance in comparison to low milk prices, the current state of dairy animal welfare in Canada and how it compared to the United States and other livestock sectors, practices consumers believed to be important for proper dairy animal welfare, as well as what they would pay for animal welfare friendly milk. The results suggested Canadians believed animal welfare was important and that the Canadian dairy animal was currently acceptable. Consumers believed outdoor access and banning growth hormones were important. Finally, a majority indicated they would purchase animal welfare friendly milk.

Para realizar tal análise nos utilizamos da avaliação do diagrama cor-cor como primeiro critério de seleção para a procura de estrelas com excesso de infravermelho, das quais 47 estrelas foram selecionadas, depois analisamos as distribuições espectrais de energia ou SED onde 29 estrelas foram selecionadas e para confirmação do excesso de infravermelho, passamos pela inspeção visual, onde das 29 estrelas apenas uma não apresentou contaminação por background de galáxias ou por uma estrela próxima. Na inspeção visual, e nas SEDS analisamos o excesso nas bandas W1, W2 e principalmente nas bandas W3 e W4 do satélite WISE. Por fim calculamos a temperatura dessa poeira em aproximadamente 200K. / This work has focused primarily on the analysis of infrared of 1916 red giant stars Pinsonneault catalog. To perform this analysis we use the evaluation of the color-color diagram as a first selection criterion looking for stars with infrared excess, of which 47 were selected stars, then we analyze the spectral energy distributions or SED where 29 stars were selected and infrared excess of confirmation, We passed the visual inspection, where the 29 stars one, the KIC9728845 star, showed no contamination by background galaxies or a nearby star. On visual inspection, and the SEDS analyzed over the bands W1, W2 and W3 mainly by bands and bands W3 and W4 satellite WISE. Finally we calculate the tempertura this dust at about 200K.
