Full textSelon plusieurs études, les paramètres physiques ont une influence très variable sur la dégradation de la matière organique pendant le compostage, ce qui suggère un certain niveau d'interaction. L'objectif du présent projet était justement de mesurer l'effet interactif sur la décomposition du compost, de l'humidité (H), du ratio massique de boues d'usine d'épuration et d'agent structurant (B/AS), et de la granulométrie (G) de l'agent structurant composé de résidus ligneux de compostage. Seize (16) recettes de compost, de 3 kg et offrant divers taux de H, B/AS et G, furent chacune incubée à 40 °C dans un respiromètre pendant quatre (4) semaines tout en mesurant leur taux d'assimilation d'oxygène. Les résultats de cette étude ont démontré qu'après 14 et 28 jours, l'assimilation totale d'oxygène était influencée de façon significative par H, le ratio B/AS et la G, ainsi que l'interaction entre le H et le ratio B/AS (p<0.05). Les résultats furent analysés par la méthode statistique d'analyse de régression linéaire multiple afin de générer un modèle capable de prédire la consommation cumulative et moyenne d'oxygène après 14 et 28 jours en fonction des paramètres physiques significatifs citées ci-haut (R2=0.84). L'assimilation d'oxygène des mélanges, telle que prédite par le modèle, est grandement influencée par l'interaction entre le H et le ratio B/AS. L'assimilation cumulative d'oxygène des mélanges à 14 jours (R2=0.78) était plus facile à prédire que celle à 28 jours (R2=0.57). Par contre, la prédiction de l'assimilation d'oxygène devient plus précise à 28 jours lorsque les valeurs mesurées à 14 jours sont inclus

Purpose: Oxygen uptake (VO2) has been shown to be controlled by a nonlinear system, yet the VO2 response to ramp style exercise appears linear. We tested the hypothesis that an integrative model incorporating nonlinear parameter values could accurately estimate actual VO2 responses to ramp style exercise. Methods: Six healthy, men completed three bouts of varying ramp rate exercise (slow ramp (SR): 15 W/min, regular ramp (RR) 30 W/min, fast ramp (FR) 60W/min) and four bouts of extended-step incremental exercise, where each step lasted 5-15 min or until volitional fatigue on a cycle ergometer on separate days. The step-responses were then fit with a simple monoexponential starting at time zero (MONO) or allowing a time delay and using only the first 5 min of data (5TD). The resulting VO2 parameters from the step protocol were incorporated into an integrative model for the estimation of the VO2 response to each of the rates of ramp incremental exercise. The parameters from the actual and model ramp protocols were compared with 2 way repeated-measures ANOVAs. Results: Both Gain (G) and Mean Response Time (MRT) (or time constant) values increased significantly across work rate transitions (mean±SD; Gain:10.0±0.9, 11.6±1.1, 13.1±1.3, 17.6±3.3 ml O2/min/W; MRT:39.4±7.7, 54.0±5.4, 79.6±15.0, 180.1±56.2 s). Up to maximalVO2 the models over-estimated the actual VO2 response for FR (Gain: ACT 8.7±1.0, MONO 9.9±0.4, 5TD 10.3±0.3 ml O2/min/W). Up to 80% maximal VO2 the models accurately predicted the actual VO2 response across all ramp rates (Gain: ACT 10.7±1.1, 10.2±0.5, 9.2±1.0; MONO 11.0±0.8, 10.3±0.6, 9.2±0.5; 5TD 10.4±0.4, 10.2±0.3, 9.8±0.2 ml O2/min/W, values are listed SR,RR,FR). Conclusions: When variable parameter values (G and either MRT or time constant and time delay) were utilized by an integrative model, accurate estimations of the VO2 response to ramp incremental exercise were possible regardless of ramp rate (up to 80% maximal VO2). The increases in both G and MRT (or time constant) appear to balance each other to produce the quasi-linear VO2 responses.

Full textDirectly measured peak oxygen uptake (VO2peak) is established as an important prognostic marker of cardiovascular disease and premature mortality, but is rarely evaluated for prevention purposes or in primary care settings due to costly and time-consuming procedures. Both VO2peak and several other health parameters can, however, be improved and maintained by regular exercise, and today`s recommendations suggest that all adults should do at least 150 minutes of moderate intensity or 75 minutes or vigorous intensity exercise per week. Hence, the total recommended volume or energy expenditure may be reached by strictly different approaches. In the current thesis, data on directly measured VO2peak in 4631 individuals from the third wave of the Nord-Trøndelag Health Study (HUNT 3, 2006-08), were used to first derive a simple prediction model for VO2peak that potentially could supplement direct measurements in healthcare settings and for research purposes. Next, the clinical utility of this model was examined by its ability to predict all-cause and cardiovascular mortality in a large sample of healthy men and women from the HUNT 1 (1984-86) cohort. Furthermore, we examined how different combinations of intensity and total time spent at habitual exercise were associated with VO2peak in apparently healthy, community dwelling individuals from HUNT 3. The findings in this thesis indicate that VO2peak can be predicted with reasonable accuracy by using easily available clinical and selfreported variables such as age, body composition, self-reported physical activity and resting heart rate, and that the model can be used to correctly classify subjects in the correct tail of the VO2peak distribution. For each metabolic equivalent (i.e. MET, ~3.5 mL∙kg-1∙min-1) higher CRF, the risk of CVD mortality was 21% lower in both men and women who were below 60 years at baseline, while the corresponding risk of all-cause mortality was 15% and 8% lower in men and women, respectively, for each MET higher CRF. Furthermore, we demonstrate that habitual exercise patterns of moderate intensity for a long total duration or vigorous intensity for a relatively short duration, adding up to the total volume as recommended by the health authorities, both were associated with a beneficial VO2peak –level. However, a higher VO2peak was observed among those reporting vigorous intensity compared to low and moderate intensity for a similar time spent, and energy expenditure used during exercise.

Full textIl devient de plus en plus évident que les émissions anthropiques de CO₂ ont une influence sur le climat de notre planète et que les conséquences pourraient en êtres dévastateurs pour la population. La production d'énergie par la combustion de combustibles fossiles est la cause principale de ces émissions, mais elle est aussi essentielle à notre mode de vie et même, notre survie. Il est donc nécessaire que nous développions des carburants renouvelables qui sont aussi économiquement viables pour assurer que nous avons l'énergie nécessaire pour soutenir notre société dans l'avenir. À cette fin, il a été proposé que les effluents des industries contenant de grandes quantités de CO₂ pourraient êtres traités en utilisant des algues. Elles consumeraient le carbone et ensuite pourraient êtres récoltées pour produire des biocarburants. Grâce à la photosynthèse, les algues produisent également de l'oxygène comme sous-produit. Dans la culture d'algues généralement envisagé, cet oxygène est produit en faible concentration et est donc rejeté dans l'atmosphère, ayant aucun usage industriel.Dans cette étude, nous proposons deux scénarios dans lesquels un système photobioréacteur d'algues pourrait êtres développés pour générer un produit précieux de l'air enrichi en oxygène, ou de l'oxygène pur. La récupération de ce produit habituellement négligé a le potentiel de faire la capture du carbone et la production de biocarburants plus économiquement viables. Pour savoir si un tel système est réalisable, il est important de savoir si les algues sont capables de survivre dans les conditions présentes dans les systèmes. Les concentrations de CO₂ et de l'oxygène dans ces systèmes proposés seraient considérablement plus élevées que ceux de l'air ambiant. Nous démontrons que ces deux processus proposés pour la production d'oxygène sont en fait réalisables. En plus de cela, les fortes concentrations d'oxygène et de CO₂ peuvent avoir un léger effet négatif sur les taux de croissances des algues, mais que leurs croissances ne sont pas complètement empêchées. Finalement, nous démontrons que le potentiel de production d'oxygène de trois différentes espèces d'algues (Anabaena sp., Synechococcus sp., et Chlamydomonas reinhardtii) est à peu près identique, ce qui suggère que les systèmes que nous avons proposé peuvent être compatibles avec de nombreuses espèces d'algues.

Full textIncludes bibliographical references.
Maximal oxygen consumption (VO2max) is typically defined by the presence of the "plateau phenomenon" during incremental exercise tests, in which O2 consumption levels-off in spite of increases in workload. This is thought to reflect a limitation in the capacity of the heart to pump O2 enriched blood to the exercising limbs. Some researchers however question not only the biological validity of the "plateau concept", based on mathematical and methodological issues, but whether O2 delivery to the exercising muscles indeed sets the upper limits for VO2max. This thesis aimed to address some of these controversies.

Full textL'avaluació del consum d'oxigen (Vo2) en natació és un procediment complex i farragós degut a les limitacions imposades pel medi aquàtic i l'equipament. Hi ha dos procediments habituals per determinar del Vo2 en el medi aquàtic: 1) el mesurament continu del Vo2 mitjançant un sistema de tub respirador, i 2) mesuraments post exercici mitjançant l’ús de màscares facials o bucals. Tanmateix, l'ús de tubs respiratoris modifica la tècnica i la hidrodinàmica, fet que redueix la velocitat i impossibilita les fases subaquàtiques en sortides i viratges. Per superar aquests problemes s’ha utilitzat la retroextrapolació de la corba de recuperació del Vo2 per predir el 𝑉o2peak durant la natació lliure, però sovint es produeix un error d’estimació derivat d'un retard en l'inici de la recuperació del Vo2. En aquesta tesi, s’avalua un model matemàtic basat en la cinètica de la freqüència cardíaca (FC) i el Vo2 post exercici per l'estimació del Vo2 durant l’esforç (estudi I). Posteriorment, per avaluar la validesa del mètode en l'estimació del 𝑉o2peak, es van comparar els mesuraments de Vo2 durant proves de natació supramaximal amb diversos mètodes comunament utilitzats (estudi II) i en diferents distàncies (200 i 400 m) (estudi III). En aquesta investigació demostrem que el nou procediment de modelatge basat en mesures del Vo2 post exercici i en la cinètica de la FC és un mètode vàlid i acurat per estimar el 𝑉o2peak en nedadors en 200 o 400 m, indistintament, i evita el biaix d'estimació produït per altres mètodes. Per tant, aquest nou procediment es presenta com el mètode a escollir per avaluar, en condicions de natació completament lliure, les capacitats cardiorespiratòria i metabòlica en nedadors de competició.
