Le symbole de l’eau et de la montagne, convergences et divergences au sein de la trilogie de l’écrivain colombien William Ospina et dans la poésie andine contemporaine / The symbol of the water and the mountain, the convergences and the differences within the trilogy of the Colombian writer William Ospina and in the contemporary Andean poetry

Pinzon Hernandez, Carolina 08 July 2016 (has links)
A travers l’étude isotopique de la trilogie de William Ospina, et des poèmes des représentants de « l’oralitture » latinoaméricaine, elle témoigne du processus d’acculturation et certainement de ce système de représentations que l’on désigne par Andin. La question de « l’andinité » est mise en évidence à travers les répétitions des sèmes et des termes construisant les symboles mythiques de l’eau et de la montagne que nous analysons en tant qu’isotopies. La problématisation concerne l’adoption de symboles, l’adaptation ou le transfert, mais aussi la résistance et le rejet des symboles mythiques issus du bagage symbolique chrétien. Or, si le monde des cordillères et ses eaux transparait le substrat précolombien, il y a aussi des liens entre le sens que la tradition européenne partage avec les cultures andines. / Through the isotopic study of the trilogy written by William Ospina, as well as the poems of the representatives of the Latin-American “oralitura”, it gives evidence of an acculturation process and a representation system that we designed as Andean. The question of “andinity” is manifested by repetitions of semes and terms which build up the mythical symbols of the water and the mountain that we analyze as isotopies. The research question concerns the adoption, adaptation or transfer of symbols, but also the resistance and rejection of the symbols coming from a Christian symbolic background. Nevertheless, if the world of the hills and the water lets the pre-Columbian substratum show itself, there are also links between the sens European tradition shares with Andean cultures.

Physiological and Performance characteristics of Elite Mountain Bike Cyclists

Linaker, Kelly, n/a January 2004 (has links)
Cross-country (XC) mountain bike (MTB) riding is a new cycling discipline and research examining the physiological demands of MTB racing is limited. The purpose of this study was to comprehensively measure physiological characteristics, to identify the performance demands of XC and time trial (TT) MTB racing and to simulate a field MTB race in the laboratory to measure the physiological responses associated with racing. Twelve male and four female elite MTB cyclists volunteered to take part in this study. Subjects completed maximal aerobic power and, anaerobic power and capacity tests. MTB race data was collected during TT and XC competitions with SRM MTB power cranks fitted to the subjects MTB. Five male MTB cyclists (V . O2max 72.0 +/- 4.6 ml/kg/min-1, maximum power output (MPO) 5.40 +/- 0.30 W/kg-1, maximum heart rate (HRmax) 189 +/- 7 bpm) performed two laps of a MTB course in the field using their race bikes with MTB SRM power cranks fitted. A laboratory MTB race simulation was performed using a wind braked ergometer. Cyclists attempted to match the average and peak power output (W/kg-1) achieved in the field trial in the laboratory. Power output (PO), heart rate (HR) and cadence (revolutions per minute, rpm) were measured during field and laboratory trials, while oxygen uptake (V . O2) was determined only during the laboratory simulation. Results showed TT MTB racing is significantly shorter in duration and distance than XC racing and significantly higher for power output and heart rate, with more time spent above anaerobic threshold (16.0 +/- 2.4 and 22.8 +/- 4.3% time) and MPO (38.4 +/- 5.2 and 26.5 +/- 9.4% time) than XC racing (p<0.05). Mean power output and heart rate between the field and laboratory trials were similar (4.18 +/- 0.55 and 4.17 +/- 0.15 W/kg-1 respectively, 175 +/- 9 and 170 +/- 8 bpm). Time spent below 2 W/kg-1 and above 6 W/kg-1 for the field and laboratory trials accounted for ~32% and ~30% of the total time, respectively. During field and laboratory trials, cyclists utilised 77.8 and 77.3% of MPO, 93 and 90% of HRmax, respectively. There was a significant difference between mean cadence in the field and laboratory trials (60.3 +/- 9.1 and 75.2 +/- 7.0 rpm, respectively, p<0.05). The cadence band of 60-69 rpm showed a significant difference between the time spent in that band from the field (14.6%) to the laboratory (4.6%). The time spent above a cadence of 80 rpm in the field was 29.8% compared to the laboratory at 62.0% of the time. Mean and peak V . O2 for the simulation was 57.5 +/- 3.3 and 69.3 +/- 4.4 ml/kg-1/min-1 respectively, with cyclists sustaining an average of ~80% V . O2max. In summary, MTB competition requires multiple short-high intensity efforts and places high demands on both the aerobic and anaerobic energy systems. The power output and heart rate responses to a MTB field race are similar when simulated in the laboratory, although in the laboratory higher cadences are selected for the higher power outputs than the field.

The Social Impact of "Brokeback Mountain:" A Reception Study

Bermudez, Pilar Aurelia 01 January 2008 (has links)
The film "Brokeback Mountain" was released in December of 2005 into mainstream theaters and to general audiences. Director Ang Lee, screenwriters Diana Ossana and Larry McMurtry, and actors Heath Ledger and Jake Gyllenhaal made this film in which the storyline revolves around two men falling in love and how this forbidden love would affect the rest of their lives. The shock of having a film with two men kissing and having sex in the theaters seemed to have struck a nerve with many viewers. Some were very positive, hailing the film as a new step in mainstream films to show a queer relationship, others were negative, criticizing the film even at times condemning what was shown on the screen. The impact of the film made debate and conversations about queer content available to a public forum, in this case newspapers from around the country.

Groundwater Dependence of Aquatic Ecosystems associated with the Table Mountain Group Aquifer.

Roets, Wietsche. January 2008 (has links)
<p>Results from this study enables a better understanding of groundwater surface water interactions in the TMG, particularly regarding aquatic ecosystems. It has also highlighted the necessity to do proper impact assessments before proceeding with bulk abstraction from this important aquifer. The results also demonstrated the importance of differentiating between real groundwater and non-groundwater discharge contributions to surface hydrology and where these interface areas are located.</p>

Mountain centered icefields in northern Scandinavia

Fredin, Ola January 2004 (has links)
Mountain centered glaciers have played a major role throughout the last three million years in the Scandinavian mountains. The climatic extremes, like the present warm interglacial or cold glacial maxima, are very short-lived compared to the periods of intermediate climate conditions, characterized by the persistence of mountain based glaciers and ice fields of regional size. These have persisted in the Scandinavian mountains for about 65% of the Quaternary. Mountain based glaciers thus had a profound impact on large-scale geomorphology, which is manifested in large-scale glacial landforms such as fjords, glacial lakes and U-shaped valleys in and close to the mountain range. Through a mapping of glacial landforms in the northern Scandinavian mountain range, in particular a striking set of lateral moraines, this thesis offers new insights into Weichselian stages predating the last glacial maximum. The aerial photograph mapping and field evidence yield evidence that these lateral moraines were overridden by glacier ice subsequent to their formation. The lateral moraines were dated using terrestrial cosmogenic nuclide techniques. Although the terrestrial cosmogenic nuclide signature of the moraines is inconclusive, an early Weichselian age is tentatively suggested through correlations with other landforms and stratigraphical archives in the region. The abundance and coherent spatial pattern of the lateral moraines also allow a spatial reconstruction of this ice field. The ice field was controlled by topography and had nunataks protruding also where it was thickest close to the elevation axis of the Scandinavian mountain range. Outlet glaciers discharged into the Norwegian fjords and major valleys in Sweden. The process by which mountain based glaciers grow into an ice sheet is a matter of debate. In this thesis, a feedback mechanism between debris on the ice surface and ice sheet growth is presented. In essence, the growth of glaciers and ice sheets may be accelerated by an abundance of debris in their ablation areas. This may occur when the debris cover on the glacier surface inhibits ablation, effectively increasing the glaciers mass balance. It is thus possible that a dirty ablation area may cause the glacier to advance further than a clean glacier under similar conditions. An ice free period of significant length allows soil production through weathering, frost shattering, and slope processes. As glaciers advance through this assemblage of sediments, significant amounts of debris end up on the surface due to both mass wastage and subglacial entrainment. Evidence that this chain of events may occur, is given by large expanses of hummocky moraine (local name Veiki moraine) in the northern Swedish lowlands. Because the Veiki moraine has been correlated with the first Weichselian advance following the Eemian, it implies a heavily debris charged ice sheet emanating from the mountain range and terminating in a stagnant fashion in the lowlands.

Pathogenicity and taxonomy of fungi associated with the mountain pine beetle in British Columbia

Plattner, Alex 05 1900 (has links)
The mountain pine beetle is associated with a diverse array of fungi. Grosmannia clavigera is the most pathogenic of these fungi. A comparison was made between two methods that have been used to assess fungal pathogenicity. Results were similar for older trees inoculated with G. clavigera using either the alternating flap technique or cork borer method. Using the cork borer method, younger lodgepole pine trees were inoculated with five different isolates of G. clavigera. After a 48 week incubation period, isolates ATCC 18086, B5 and H55 had induced stronger pathogenic indicators compared to isolates KW 1407 and B20. After a 7 week incubation period, only isolate ATCC 18086 had induced stronger pathogenic indicators. Usually, this isolate grew faster at lower temperatures and in a low oxygen environment. Isolate KW 1407 consistently produced milder pathogenic indicators during both incubation periods. Among the non-pathogenic fungal associates of the mountain pine beetle, Ceratocystiopsis minuta may be considered the most important because it is the type species for the genus Ceratocystiopsis. The history of this genus is complicated because no physical specimen exists for C. minuta. The phylogeny of the genus Ceratocystiopsis was evaluated. Many isolates of C. minuta were assessed as potential epitypes. Several isolates of C. minuta from previous work were shown to be misidentified. C. minuta isolate CBS 116796 is recommended for future genetic work within the genus Ceratocystiopsis. For morphological work, using measurements from the literature is recommended since CBS 116796 did not produce fruiting bodies.

Quality of bluebunch wheatgrass (Agropyron spicatum) as a winter range forage for Rocky Mountain Elk (Cervus elaphus nelsoni) in the Blue Mountains of Oregon

Bryant, Larry Duane 07 May 1993 (has links)
This research was conducted on three study areas on elk winter ranges in Northeast Oregon. One was on the Starkey Experimental Forest and Range and the others were in the same vicinity. Plant appendages, spring and fall defoliation and fall growth of bluebunch wheatgrass were evaluated in terms of quality of nutrient content during September through April of 1986-87 and 1987-88. Four treatments were applied. Plants were clipped to a 2.5 cm and 7.6 cm stubble height in the spring before the boot stage of phenological development; plants were clipped to a 7.6 cm stubble height in the fall after plant maturity in September; plants were not clipped during the year. Percent crude protein, dry matter digestibility (DMD), acid detergent fiber (ADF), and lignin were evaluated monthly. Samples from the four treatments were also analyzed from October to April to determine monthly changes in nutrient contents. Production of growth from all treatments was measured in October and March each year. Leaf material had higher percent crude protein and DMD, with lower percent ADF and lignin than the inflorescence and culm. The third leaf (the youngest plant material) had the highest nutrient value of all appendages. The culm and inflorescence values were not statistically different. Growth following spring defoliation treatments produced higher percent crude protein and DMD (P<.05), with a lower percent ADF and lignin than non-treated plants in both years. This was particularly pronounced during 1986 when precipitation in late summer initiated fall growth. Growth following spring defoliation and bluebunch wheatgrass not defoliated did not produce crude protein or DMD values sufficient to meet minimum dietary maintenance requirements for elk. Fall precipitation adequate to promote fall growth occurred only in 1986. Growth after fall defoliation had the highest percent crude protein and DMD with the lowest ADF and lignin values of all vegetation sampled. However, without 3-5 cm of late summer/early fall rains, fall growth does not occur. This happened in 1987. When growth does occur in fall the quality of the growth exceeds the minimum dietary maintenance requirements for elk. Freezing and thawing of fall growth plant material had minimal effect on forage quality. There were differences (P<.05) between the monthly values for percent crude protein and ADF starting in October and ending in April. However, the percent DMD and lignin from October to April were not different (P<.05). / Graduation date: 1993

Watershed modeling at Yucca Mountain, Nevada

Britch, Michael J. 24 July 1990 (has links)
Studies are currently underway to determine the suitability of Yucca Mountain in Nevada as the nation's first high-level nuclear waste repository. Values of net infiltration are required to determine pre-waste emplacement groundwater travel times and the performance of the repository as a waste containment system. The objective of this study was to develop a numerical model to perform water balance calculations and predict rates of net infiltration for the site. The model included processes of precipitation, runoff, evapotranspiration, infiltration, and redistribution of water within a soil profile. The watershed was divided into 477 grid cells 75.7 x 75.7 m. The elevation, slope, aspect, and hydrologic properties were assumed to be constant within a grid cell but varied from one cell to the next Water balance calculations were performed for each cell using a one-dimensional form of Richards equation. The solution was obtained using the finite difference method with Newton-Raphson iteration. The model was calibrated using water content data obtained from neutron-moisture meter measurements in boreholes located in Pagany Wash Watershed Measurements were made in channel and terrace alluvium and in tuffs. Computer simulations reproduced water content data for a major precipitation event that occurred in 1984. Simulations verified the importance of antecedent soil water content in controlling the occurrence of runoff. Sensitivity analysis indicated that the soil and alluvium grain-size distributions, which are used to calculate unsaturated hydraulic conductivity, can greatly affect predicted rates of water movement / Graduation date: 1991
