Various models for predicting profile available water capacity (PAWC) from laboratory measurements were compared with published field values for the same sites. The intention was to choose the best model/s to predict PAWC, by using a database, for a wide range of soils in the Burdekin Irrigation Area, North Queensland. Effective rooting depth for all models was estimated from the chloride profile. It was found that the predictive abilities of all models used were dependent on soil types. A conventional model (ASWC) based on the difference between water retained at -33 and -1500 kPa matric potentials was higher (P < 0.01) than field measured PAWC. An empirical model (PAWC2) based on cation exchange capacity (CEC) and depth was suitable only for cracking clays and sodic duplex soils. Another empirical model (PAWC1) based on -1500 kPa water retained and depth, predicted field PAWC particularly well on cracking clays, sodic duplex and related soils. There were strong indications that the PAWC1 model is also suitable for the better drained, lighter textured soils but there was a shortage of comparable field data to confirm this. The practical implication of these findings was that an analytical database can be used to predict PAWC on many Burdekin soils, providing immediate assistance to those designing irrigation channels and farm layouts.

The effect of flexible spacer length on the liquid crystalline property of ABA-type triblock copolymers containing azobenzene groups was investigated. For the study, the monomers, n-[4-(4-ethoxyphenylazo)phenoxy]alkyl methacrylates with varying methylene groups (n = 0, 2, 6) were used to synthesize a series of azobenzene-containing amphiphilic triblock copolymers PAnC-PEG-PAnC by atom transfer radical polymerization (ATRP). Differential scanning calorimetry (DSC), polarizing optical microscopy (POM), and one-dimensional X-ray diffraction (1D WAXD) have shown that the glass transition temperatures of these copolymers decreased as n increases. PA0C-PEG-PA0C has no mesophase, while both PA2C-PEG-PA2C and PA6C-PEG-PA6C have a nematic mesophase. These differences derive of the length of spacer groups between the polymer main chain and side chain.

Most upper-semester students who fail to graduate have an issue with their perceived academic writing competence (PAWC). PAWC is associated with writing self-efficacy (WSE) and writer's block (WB). Thus, improving WSE and decreasing WB are crucial for succeeding in the final project writing of the upper-semester students. Only limited studies focused on exploring academic writing practice for vocational students by survey strategy. This study used a quantitative approach to test the hypothesis that WSE and WB positively affect PAWC. Respondents were selected using random sampling involving 200 students from a vocational school in Surakarta. Respondents filled survey about PAWC, WSE, and WB consisting of 18 items. The hypothesis was tested by multiple regression analysis. The study results revealed that WSE and WB are positively correlated with PAWC. This research implies that faculty members are advised to focus on encouraging WSE and reducing WB to improve AW competence through curriculum improvements. With the increase in students' academic writing skills, the classic problem of late completion of studies due to late writing of the final project can be solved.

Field-crop yields are below their genetic and climatic potentials on many fine-textured soils due to low organic carbon content (OC), high bulk density (ρb), low hydraulic conductivity (Ks), insufficient air capacity (AC) and low plant-available water capacity (PAWC). Although soil conditioners derived from municipal, agricultural and industrial wastes are frequently used to improve soils, their effects on overall soil physical quality are still poorly understood. Hence, the objective of this laboratory soil core study was to determine for a Brookston clay loam the effectiveness of masonry sand, greenhouse rockwool waste, yard waste compost and swine manure compost for improving soil physical quality relative to “ideal” levels proposed in the literature, and relative to “benchmark” levels found in the soil under virgin conditions, long-term conventional tillage and long-term no-tillage. The virgin soil produced near-surface (0.05–0.15 m depth) values for ρb(0.88 Mg m-3), AC (0.19 m3m-3) and PAWC (0.22 m3m-3) that fell within the optimal ranges proposed in the literature, while OC (68.2 g C kg-1) was slightly above optimal. The soil under long-term conventional tillage and no-tillage (cornsoybean rotation) produced below-optimal organic carbon content (21.9–22.5 g C kg-1), excessive ρb (1.45–1.47 Mg m-3), insufficient AC (0.06 m3m-3) and low PAWC (0.14–0.19 m3m-3). Conventional tillage also produced below-optimal Ks (10−6 m s-1). Each conditioner could improve one or more of the above parameters, but not all five. Adding sand at 20–100 wt. % improved AC, but caused excessive reductions in OC and PAWC, and excessive increases in ρb and Ks. Greenhouse rockwool waste added at 2.5–10 wt. % improved AC and ρb, but did not improve OC and PAWC. Yard waste compost added at 3.8–20 wt. % improved OC, ρb and PAWC, but did not improve AC. Adding swine manure compost at 3.8–20 wt. % improved OC and ρb, but did not improve AC or PAWC, and decreased Ks. As no single conditioner could optimize all soil physical quality parameters, future studies using combinations of conditioners are proposed.

Spatial variability in grain yield can arise from variation in many different soil and terrain properties. Identification of important sources of variation that bear significant relationship with grain yield can help achieve more effective site-specific management. This study had three aims: (i) a geostatistical description/modelling of the paddock-level spatial structure in variability of plant-available water capacity (PAWC) and related soil properties, (ii) to determine optimal number of management zones in the paddock, and (iii) to assess if the variability in PAWC and related soil properties is significantly associated with the variability in grain yield across the management zones. Particle size distribution, bulk density (BD), field capacity (FC), permanent wilting point (PWP), and soil water content (SWC) at sowing were measured at 4 soil depths (to 0.60 m) at 50 representative spatial sampling locations across a paddock near Birchip (Victoria). PAWC and plant-available water at sowing (PAWs) were derived from these data. Moderate to strong spatial dependence across the paddock was observed. The magnitude of the structural variation and of range varied widely across different soil properties and depths. The south-east edge and the central areas of the paddock had higher clay content, FC, PWP, PAWC, and lower PAWs. The paddock was divided into 6 potential management zones using combined header yield and normalised difference vegetation index (NDVI). The adequacy of zoning was evaluated using relative variability (RV) of header yield and soil properties. The mean RV for 3 zones differed little from that of 6 management zones for header yield and for each measured soil property, indicating division of the paddock into 3 zones to be adequate. The results from residual maximum likelihood (ReML) analysis showed that low yield zones had significantly higher clay content, FC, PWP, SWC, and PAWC and significantly lower PAWs than both medium and high yield zones. The mean FC, PWP, and PAWC in the low yield zones were, respectively, 25%, 26%, and 28% higher, and PAWs 36% lower than their corresponding values in the high yield zones. Linear regression analysis indicated that 59–96% of the observed variation in grain yield across management zones could be explained by variation in PWP. The practical implications of these results are discussed.

Crop yield potential is a chief determinant of nutrient requirements, but there is little objective information available on the gains in profitability that can be made by accounting for the influences of soil type and season on yield potential when making fertiliser decisions. We conducted such an assessment using crop growth simulation coupled to nutrient response curves for wheat-growing at 4 locations in the low-medium rainfall zone of Western Australia. At each location, the yield potential was simulated on 10 soil types with plant-available water capacity (PAWC) ranging from 34 to 134 mm, which represent the major soils types in Western Australia. Soil survey maps were available to quantify soil type variability and the historical climate record (1974–2005) for seasonal variability. The benefits possible for fertiliser (NPK) management that takes account of variation in crop yield potential due to season and soil type by having ‘perfect knowledge’ ranged from $2 to 40/ha. Seasonal variation was more important than soil type for the better soils (high PAWC), providing two-thirds of the benefit of perfect knowledge. On low PAWC soils, knowledge of soils and seasonal influences on yield potential were similar contributors to profit gains. An assessment of one yield forecasting system showed that about 50% of the maximum gains could be captured if seasons could be categorised as below, at, or above average at the time the fertiliser decision is made. In each catchment, 30–40% of fields showed scope for benefits in accounting for within-field variation in soil type due to large variation in PAWC, and therefore yield. Maximum profit gains and reductions in nutrient excess were greater in the low rainfall locations and also on the low PAWC soil types.

Improved methods for field measurements of plant available soil water capacity (PAWC) of Black and Grey Vertosols in Australia’s north-eastern grain region were employed to characterise 83 soil–crop combinations over 7 depth intervals to 180 cm. Soil sub-order was shown to influence all components of PAWC (means of 224 and 182 mm in Black and Grey Vertosols, respectively) with drained upper limit (DUL), bulk density (BD), and crop lower limits (CLL) showing clear separation between soil sub-orders and a trend with soil depth. In addition to soil sub-order and soil depth effects, CLL showed crop effects such that expected PAWC of various crops when adjusted for soil sub-orders were: cotton 240 mm; wheat 233 mm; sorghum 225 mm; fababean 209 mm; chickpea 197 mm; barley 191 mm; and mungbean 130 mm. A total of 549 measured CLL values were used to develop a predictive model for estimating CLL from the soil sub-order, depth, DUL, and crop by predicting a CLL as a function of DUL and a depth-dependent variable for each crop–soil sub-order. The model CLL = DUL * (a + b * DUL) explained 85% of observed variation in the measured data with no significant bias between observed and predicted data. While properly measured data would be more reliable than estimated data, where specific site accuracy is less critical, this model may be used to estimate PAWC with an acceptable degree of accuracy.

Soil water availability to the plants is a very important physical property of soil that controls water and nutrient absorption by the plant. It is defined as the difference between the maximum amount of water the soil can hold and the minimum condition that the plant can no longer extract water from the soil. However, soil factors that control the plant available water content (PAWC) in the soil have not been fully understood. The present study aims to analyze the relations between particle-size distributions and organic carbon with the available water of the soil and to develop a model of predicting PAWC. Five soil profiles at different land units were described up to the depth of 100 cm. Ten undisturbed soil samples were taken using the stainless-made core sampler from 10 cm increments for the soil water holding capacity analysis. A similar number of disturbed samples were also provided from the same depths for soil texture and organic carbon analysis. Results showed that the variance in PAWC could be explained by sand and clay fractions (R2>0.35) but not by silt and organic carbon contents. Therefore, we were able to develop a model for the prediction of available water content in the soil from the sand and clay parameters. The model will help decision-makers be able to propose conservation and management strategies for PAWC in agricultural practices as well as for the soil moisture retention at civil works.

Clearing native vegetation and introducing crops and pastures may increase deep drainage and result in dryland salinity. In south-west Queensland, native vegetation of the Goondoola Basin has been substantially cleared for cropping and pastoral activities, resulting in shallow groundwater and localised salinity. Simulation modelling was used to estimate the water balance of a range of vegetation and soil types. Six soils were studied, with plant-available water capacity (PAWC) of 71 mm (a Kandosol) to 198 mm (a Vertosol) for 1200 mm depth. Vegetation types were annual wheat, opportunity cropping, and perennial pastures in poor and good condition, and high quality perennial pasture with deep roots growing on deep (2400 mm) variants of the 6 soil types. Opportunity cropping did not reduce deep drainage. Substantial differences were found in long-term average deep drainage (mm/year) between wheat crops and pastures for all soil types. The differences in deep drainage between wheat cropping and pasture in good condition were greatest for the 2 Kandosols, which had the lowest PAWC (34 and 21 mm/year less deep drainage, reductions of 53% and 62%, respectively), and a Vertosol with intermediate PAWC (23 mm/year less deep drainage). A Chromosol and a Dermosol with intermediate PAWC had smaller reductions in deep drainage (14 and 11 mm/year, respectively). In the case of a Vertosol with high PAWC (198 mm), deep drainage was negligible with all pastures. Due to increased infiltration and reduced soil evaporation, more deep drainage was simulated with pasture in good condition than pastures in poor condition, especially for 2 Kandosols. Pasture with deep roots (2400 mm) growing on deep variants (2400 mm) of the 6 soils had lower rates of deep drainage than the other pastures. Simulated deep drainage and other components of the water balance were in good agreement with field measurements and expectations. These results indicate that large reductions in deep drainage can be achieved in the Goondoola Basin by replacing cropping with pastoral activities. Kandosol soils used for wheat cropping should be the primary target for land use change.

To understand the factors involved in lucerne reducing drainage below the root-zone and influencing lucerne biomass production and water extraction were analysed in the south of Western Australia. The lucerne was grown for 3 years before removal. The factors investigated as part of the water extraction analysis included the rate of advance of the extraction front or extraction front velocity (EFV, mm/day), the soil plant-available water-holding capacity (PAWC, mm/m soil), and the temporal change in soil water deficit (drainage buffer, mm). The drainage buffer is related to the EFV and PAWC. A site with deep sand had the highest EFV (mean of 9.2 mm/day) but the lowest PAWC (mean of 32 mm/m soil) to a depth of 4 m. In the duplex soils the EFV was 18–34% of the deep sand EFV and the PAWC was 60–222% higher than the deep sand PAWC to a depth of 1.6–2.1 m. The EFV was reduced by the higher clay content and sodicity in the B horizon of the duplex soils. The highest drainage buffer measurements occurred in the deep sand site and the better structured duplex soils and therefore these soils will have the greater effect on reducing drainage below the root-zone. However, lucerne was able to create a drainage buffer to at least a depth of 1.5 m over 3 years and therefore contribute to a reduced drainage even on the most sodic and saline sites. Low soil pH did not affect the drainage buffer as much as soil texture and structure. Variation in biomass production of lucerne-based pastures was positively related to rainfall and water use (taking into account soil water storage and drainage losses) across sites, explaining approximately 50% of the biomass variation. Rainfall and water use could therefore be used for predicting lucerne biomass production in Western Australia. Biomass water use efficiency was highest in spring (15 kg/ha.mm) and least during autumn (4.5 kg/ha.mm).

Actuellement, la construction d’un parc éolien nécessite une étude acoustique qui doit assurer la tranquillité des habitants aux alentours et la conformité au regard de la réglementation en vigueur. Pour ce faire, des mesures acoustiques sont réalisées sur une période d’environ deux semaines. Durant ces mesures, des cycles de marche et d’arrêt des machines sont réalisés afin de mesurer la différence de niveau sonore entre le bruit ambiant (éoliennes en fonctionnement) et le bruit résiduel (éoliennes à l’arrêt). Un plan de bridage des machines est alors calculé et fourni à l’exploitant afin de l’implémenter dans le système de contrôle local des éoliennes (SCADA). Actuellement, ce plan dépend grossièrement des conditions météorologiques et des périodes de la journée, supposées corrélées aux conditions acoustiques. En pratique, cette manière de procéder engendre fréquemment des dépassements du critère réglementaire et/ou des pertes de production électrique. Ceci est dû aux conditions acoustiques qui évoluent sans cesse, à la fois pour le bruit particulier (bruit des éoliennes seules) qui dépend finement des conditions météorologiques, et pour le bruit résiduel qui dépend de toutes les autres sources de l’environnement et qui est fondamentalement de nature stochastique. La thèse vise à proposer un algorithme de contrôle du parc éolien en temps réel basé sur un nouveau paradigme de contrôle. On y étudie la possibilité de contrôler un parc éolien à partir d’un système en boite noire d’estimation temps-réel du niveau résiduel et du niveau particulier par séparation de sources. Dans le manuscrit, on définit tout d’abord une formulation du problème dans le cadre du contrôle en identifiant les problématiques propres à ce sujet, une définition des variables du problème et en se rattachant à l’état de l’art du contrôle. Ensuite, on propose deux solutions complètes de contrôle et une évaluation expérimentale. La première est une solution déterministe, qui s’appuie sur un algorithme d’optimisation combinatoire sous contrainte, et qui s’inspire du contrôle actuel des parcs éoliens tout en tenant compte de l’estimation par séparation de sources, alors supposée exacte. On y propose en outre une étude de la capacité du système déterministe à satisfaire le critère réglementaire français qui est aujourd’hui calculé à l’aide de médianes temporelles des variables acoustiques. La seconde est une solution stochastique, qui est basée sur une représentation d’état des variables acoustiques et des incertitudes gaussiennes. Elle inclut un filtrage de Kalman non-linéaire, afin de fusionner l’incertitude sur le modèle acoustique et l’incertitude de séparation de sources, un algorithme espérance-maximisation afin de ré-estimer les incertitudes du problème qui varient d’un parc à un autre, et une adaptation robuste de l’algorithme combinatoire afin de prendre en compte les incertitudes estimées
Currently, acoustic studies are required to set wind farms up. They must ensure the tranquility of the inhabitants around the farms in accordance with current regulations. For this purpose, acoustic measurements are made during a couple of weeks. When measuring, the wind turbines are periodically stopped in order to evaluate the difference between ambient noise levels (with the turbines on) and residual noise levels (with the turbines off). A curtailment plan is then computed and sent to the wind farm owner in order to set it up in the local turbine control system (SCADA). Currently, the curtailment plan roughly depends on the weather conditions and the time of the day which are allegedly correlated to the acoustic variables. In practice, it frequently leads to violations of the acoustic constraints or electrical power loss. This is because the acoustic conditions constantly and strongly evolve over time: the wind turbine noise level finely depends on the weather conditions and the residual noise level depends on all the other acoustic sources and has therefore a stochastic nature. The goal of the thesis is to design a principled real-time control algorithm for wind farms. To do so, we investigate the use of a black-box source separation system that estimates the residual noise level and the wind turbine noise level. We first provide a theoretical formulation of the problem by accounting for specific practical issues, by defining the variables of the problem and by binding these issues to the state of the art. Then, we propose two complete control solutions and run an experimental evaluation. The first solution is a deterministic algorithm based on a constrained combinatorial optimization algorithm, which is inspired by the current approach for controlling wind farms while exploiting the source separation system. Moreover, we present a study of its ability to fulfill the French acoustic constraints that are computed as temporal medians of the acoustic variables. The second solution is stochastic and based on a state-space model defined by means of Gaussian uncertainties. It features a nonlinear Kalman filter in order to fuse the uncertainties of the model and of the source separation system, an Expectation-Maximization algorithm that computes the uncertainties for a specific farm, and a robust variant of the deterministic algorithm that takes the estimated uncertainties into account when computing the optimal command

Depuis le milieu des années soixante-dix, le développement de l'activité d'amélioration-entretien des logements marque une rupture importante avec l'essor continu de la construction qui prévalait depuis trente ans. Dorénavant, les marchés de l'ancien et de l'amélioration-entretien (travaux liés à une acquisition ou travaux seuls) participe presque pour autant que le neuf à la formation de l'investissement logement. Or, cette évolution s'est répercutée sur la constitution du parc de logements, c'est-à-dire sur son mode d'accumulation, ses modalités d'acquisition et de renouvellement. Par ailleurs, les mouvements de désaffection / réaffection entre les différentes composantes du parc (résidences principales et ses différents statuts d'occupation, résidences secondaires et logements vacants) conditionnent plus que par le passé l'évolution du parc de logements. A partir de ce constat, le modèle "VIPERES" (vieillessement et répartition par statuts d'occupation) élaboré dans le cadre de cette thèse, constitue un modèle d'analyse et de projection du parc dont l'objet est de dresser l'inventaire physique permanent du "capital-logement" au travers de ses conditions d'accumulation, d'épuisement et de transformation par mobilité. .
Since the mi-1970s. , the development of the activity of housing improvement/upkeep has marked an important break with the continuous growth of house construction which had prevailed during the previous thirty years. Since the mid-1970s, the second-hand market and the market for improvement/upkeep (improvement work linked to a purchase or improvement work on its own) have contributed in almost as great a measure as new construction to housing investment. Now, this evolution has had repercussions on the composition of the housing stock, that is to say on the way the housing stock is accumulated, acquired and renewed. Moreover, the tendencies towards decommisioning and reallocation between the different sections of the housing stock (main residences, second residences and vacant housing) condition the development of the housing stock more than they did in the past. .

Le secteur de la villette a ete consacre, des son integration dans l'espace parisien, au secteur des produits carnes, marche et abattoirs, qui vont sans trop de difficultes, approvisionner paris et toute la region ile de france, jusqu'a la veille de la seconde guerre mondial. Leur renovation, dans les annees 1955, a abouti a un echec, conduisant a la fermeture de ces deux equipements. Cette fonction premiere disparue, le site a vu se developper une multitude d'activites variees, plus ou moins populaires et soontanees. Depuis une dizaine d'annees, un projet de renovation global de cet espace de 55 hectares a progressivement ete concu et est en train de voir le jour. Changeant radicalement de destination et rompant avec la tradition populaire du quartier, c'est un centre culturel polyvalent que les responsables publics ont decide d'edifier. Le parc de la villette qui est en cours de realisation aux lieu et place du marche et des abattoirs, melera habilement loisir et culture. D'une conception nouvelle, il sera dote d'equipements aussi differents que la cite des sciences, la geode, la cite de la musique et la grande halle rehabilitee, integres dans un parc urbain du "vingt et unieme siecle". Il constitue le prototype d'une nouvelle generation de centres polyvalents scientifiques, techniques et musicaux, actifs et vivants. Le parc de la villette et plus largement, l'ensemble du site, constituera un equipement socio-culturel exceptionnel qui donnera lieu a une frequentation locale, nationale et internationale.

From the moment the villette area become integrated into the parisian infrastructure it was devoted to meat products, its cattle market and slaughter-houses were to supply paris and the ile-de-france region until the eve of the second world war. In the mid 1955, the modernisation of these two facilities ended in failure which in term, led to their being close down. Once its original usages had vanished, the area was the site of the growth of numerous varied activities more or less popular and spontaneous. For the last ten years, a project for the overall modernisation of this area (55 hectares), has progressively been designed and is now caming to fruition. The planning authorities have decided to built up a wide ranging cultural centre thus radicaly modifying the original usage of the area and breaking away from the popular tradition of the district. The parc de la villette which is being built where the cattle market and sloughter-houses used to stand, will manage to offer the public both leisure and cultural activities. Of a totaly new design, it will be equiped with buildings as varied as la cite des sciences, la geode, la cite de la musique and la grande halle renovated, will become part of an urban parc for the twenty first century. It is the very prototype of a new generation of scientific technological and musical centres.

Dans ce mémoire de maîtrise, nous présentons dans un premier temps un algorithme de l'état de l'art appelé Forêts aléatoires introduit par Léo Breiman. Cet algorithme effectue un vote de majorité uniforme d'arbres de décision construits en utilisant l'algorithme CART sans élagage. Par après, nous introduisons l'algorithme que nous avons nommé SORF. L'algorithme SORF s'inspire de l'approche PAC-Bayes, qui pour minimiser le risque du classificateur de Bayes, minimise le risque du classificateur de Gibbs avec un régularisateur. Le risque du classificateur de Gibbs constitue en effet, une fonction convexe bornant supérieurement le risque du classificateur de Bayes. Pour chercher la distribution qui pourrait être optimale, l'algorithme SORF se réduit à être un simple programme quadratique minimisant le risque quadratique de Gibbs pour chercher une distribution Q sur les classificateurs de base qui sont des arbres de la forêt. Les résultasts empiriques montrent que généralement SORF est presqu'aussi bien performant que les forêts aléatoires, et que dans certains cas, il peut même mieux performer que les forêts aléatoires.
In this master's thesis, we present at first an algorithm of the state of the art called Random Forests introduced by Léo Breiman. This algorithm construct a uniformly weighted majority vote of decision trees built using the CART algorithm without pruning. Thereafter, we introduce an algorithm that we called SORF. The SORF algorithm is based on the PAC-Bayes approach, which in order to minimize the risk of Bayes classifier, minimizes the risk of the Gibbs classifier with a regularizer. The risk of Gibbs classifier is indeed a convex function which is an upper bound of the risk of Bayes classifier. To find the distribution that would be optimal, the SORF algorithm is reduced to being a simple quadratic program minimizing the quadratic risk of Gibbs classifier to seek a distribution Q of base classifiers which are trees of the forest. Empirical results show that generally SORF is almost as efficient as Random forests, and in some cases, it can even outperform Random forests.

The thesis studies the following problem: given a set of geometrical figures (such as planar polygons), each one labelled according to whether or not it resembles some 'ideal' figure, find a good approximation to that ideal figure which can be used to classify other figures in the same way. We work within the PAC learning model introduced by Valiant in 1984. Informally, the concepts under consideration are sets of polygons which resemble each other visually. A learning algorithm is given collections of members and non-members of a concept, and its task is to infer a criterion for membership which is consistent with the given examples and which can be used as an accurate classifier of further example polygons. In order to formalise the notion of a concept, we use metrics which measure the extent to which two polygons differ. A concept is assumed to be the set of polygons which are within some distance of some fixed central polygon. In the thesis we work most extensively with the Hausdorff metric. Using the Hausdorff metric we obtain NP-completeness results for several variants of the learning problem. In particular we show that it is hard to find a single geometrical figure which is close to the positive examples but not to the negative examples. This result holds under various assumptions about the specific geometrical figures under consideration. It also holds for several metrics other than the Hausdorff metric. Despite the NP-completeness results mentioned above we have found some encouraging positive results. In particular, we have discovered a general technique for prediction. (Prediction is a less demanding learning model than PAC learning. The goal is to find a polynomial-time algorithm which takes as input a sample of labelled examples and is then able to predict the status of further unlabelled examples in polynomial time).

Many microorganisms, and in particular fungi, are able to grow over a wide pH range. Thus, these microorganisms must possess some regulatory mechanism or system that senses the environmental pH signal and ensures that gene expression of certain molecules is tailored to the pH of the environment (Penalva and Arst, 2002). In Aspergillus species and several other fungi, pH regulation is mediated by seven genes viz. palA, palB, palC, palF, palH, palI and the global pH regulatory gene, pacC (MacAbe et al, 1996; Negrete-Urtasun, 1999; Denison, 2000). The activated form of the PacC protein activates genes that are required at alkaline pH, e.g. genes coding for alkaline phosphatases, and represses certain genes that are functional at acidic pH, e.g. genes encoding acid phosphatases (Negrete-Urtasun, 1999). PacC (and its homologues) also positively regulates genes involved in penicillin biosynthesis, e.g. the isopenicillin N synthase gene, ipnA, in A. nidulans (Penalva and Arst, 2002). It has also been hypothesised that pacC may negatively regulate aflatoxin biosynthesis, a carcinogenic secondary metabolite in several species of Aspergillus (Keller et al, 1997). To elucidate the role of pacC a novel method of post-transcriptional gene silencing known as RNA interference was utilized. This method involved the cloning of a partial pacC gene fragment first in the forward and then the reverse orientations in a fungal expression cassette to create an RNA interference (RNAi) vector. The unique structure of this vector would allow the cloned fragments to be expressed and the resulting RNA to immediately form a double stranded stem-loop structure or short hairpin RNA (shRNA; McDonald et al, 2005). The formation of this shRNA, in turn, would be responsible for activating the endogenous RNA degradation complexes that would lead to mRNA degradation and subsequent gene silencing (Liu et al, 2003; Kadotoni et al, 2003; McDonald et al, 2005). The results presented here have shown that confirmed pacC RNAi mutants produced aflatoxins irrespective of environmental pH (i.e. the mutants produce aflatoxins under acidic and alkaline conditions). Thus, pacC is essential for pH regulation of aflatoxin production in A. flavus. There are numerous other biological (e.g. presence of oxylipins, lipooxygenases) and non-biological factors (pH, carbon source etc.) which affect maize colonisation and aflatoxin production by A. flavus (Burrow et al, 1996; Wilson et al, 2001; Calvo et al; 2002; Tsitsigiannis et al, 2006). However, all the genetic mechanisms involved have as yet not been identified. It has been shown by Caracuel et al (2003) that pacC acts as a negative virulence regulator in plants and these workers have hypothesised that PacC prevents expression of genes that are important for infection and virulence of the pathogen. Therefore the physiological effects that pacC silencing had on the growth, conidiation and pathogenicity of A. flavus mutants were also investigated. The results of this study showed that pacC does not play a significant role in primary growth and development but does affect conidial production. SEM results showed that mutants have many “open ended” phialides and poorly developed conidiophores. This would suggest that pacC activation of conidial production genes is also required. Furthermore, pacC RNAi silencing severely impaired the ability of the A. flavus mutants to infect and cause damage on maize. The results obtained here are similar to that of pacC null mutants in A. nidulans, C. albicans and F. oxysporum which also exhibited low pathogenicity (Davis et al, 2000; Fonzi, W.A, 2002; Caracuel et al, 2003; Bignell et al, 2005 and Cornet et al, 2005). This study indicates that pathogenicity of A. flavus on maize is directly related to the structural integrity of conidia, which in turn is greatly influenced by PacC. This gene is a global transcriptional regulator and may either repress or activate one or many genes in each of the above pathways (Penalva and Arst, 2002). Studies on the genetic mechanisms of pacC regulation on these pathways are needed to elucidate the mechanisms of activation or repression of these genes.

The poly (A)-binding protein (PABP) is an essential protein found in all eukaryotes and functions in mRNA metabolic and translational processes. Structurally, PABP consists of two distinct regions. The N-terminal half contains four RNA recognition motifs that bind to the poly (A)-tail of mRNA, while the C-terminal segment contains a unique peptide binding module referred to as the PABC domain. The function of this domain in PABP is to recruit proteins containing a very specific 'PAM-2' motif to the mRNP complex. Unique to metazoans, a PABC domain is also found in the hyperplastic discs tumor suppressor (HYD), which is an E3 ubiquitin ligase.
This thesis completes a structural investigation of PABC domains from various species by nuclear magnetic resonance spectroscopy. In particular, we report the solution structure of PABC from the parasite Trypanosoma cruzi and plant Triticum aevestium PABP. Both domains consist of five alpha-helices which fold into a structure highly comparable to the human PABC domain from PABP and HYD. All four PABCs interact with a similar PAM-2 sequence and show comparable peptide binding surfaces. The human PABC-PAM-2 complex structure displays a PAM-2 peptide interacting with specific residues within the domain. Sequence analyses and peptide surface mapping studies show that these residues are highly conserved, which indicates an analogous mechanism of peptide recognition throughout animal, parasite, and plant species. An exception to these observations was found in the PABC domain from Saccharomyces cerevisiae PABP. Yeast PABC recognizes a variation of the typical PAM-2 motif but mediates its interaction through a similar mechanism as human PABC.
The PAM-2 motif encloses a signature sequence which was used to successfully identify new interacting partners for the PABC domain via a bioinformatics screen. In mammalian systems, the identified proteins are implicated in either RNA metabolic, translational, or ubiquitin associated functions. This thesis concludes with a model illustrating a unique cross-talk between major gene expression pathways mediated by the PABC domain and its binding partners.

Depuis maintenant plusieurs années, on observe au Québec une augmentation de la popularité des activités de plein air reliées au milieu naturel. Cette augmentation peut s'expliquer par divers facteurs, parmi lesquels la conscientisation des gens face à l'environnement qui les entoure occupe une part importante. Cet engouement pour les activités en milieu naturel est bien plus qu'une simple mode passagère. En effet, les prochaines années connaîtront vraisemblablement une augmentation des superficies affectées à l'aménagement des parcs et des espaces verts dans les agglomérations urbaines. C'est dans ce contexte que s'inscrit ce document. Le plan d'aménagement du parc Gouin se veut un outil de planification destiné à favoriser la pratique d'activités de plein air en milieu naturel. Il propose diverses interventions, dont chacune a son utilité propre. L'ensemble des propositions permettra une utilisation harmonieuse du patrimoine naturel du parc. Le document comporte six parties. La première aborde le cadre de l'étude, soit l'implication de la ville de Richmond face au développement du parc. La seconde partie constitue une étude de terrain, suivit, en troisième lieu, de l'analyse des potentiels et des contraintes d'aménagement. La quatrième partie expose les orientations du parc, qui constituent les lignes directrices de développement. On retrouve le plan concept du parc en cinquième partie et finalement, la dernière partie décrit les différents aménagements à réaliser.

In this study we determine the pressure on the central area of each of the weight bearing pads of the paws of dogs at the walk. Pressure signal data from stance phase during walking were analyzed. Within paws, there were significant pressure differences among pads on both fore and hind limbs. The coefficient of restitution, the embedding dimension, and the Lyapunov exponents were calculated. The ability to measure and analyze pressure on individual paw pads provides insight into soft tissue stresses on the palmar/plantar surface of the paw. Pressure at a wound site on the pads has a detrimental effect on wound healing and a better understanding these stresses will be of benefit when suturing and bandaging pad wounds. Such information is especially important in athletic and working dogs, e.g. search and rescue dogs.

The materials of this article are devoted to research on determining the main strength characteristics of the pointed leg working body, the main difference between which and the traditionally used ones is the variable angle of crumbling. The purpose of this article was to determine the basic strength characteristics in typical cross sections ploskorezy Lancet paws, as well as identifying the degree of influence of cross-sectional dimensions of racks for efficiency. the features include the study of changes in the stress state occurring in the paw working organ in its characteristic sections, and as a consequence, the effect of these changes on the rigid rack. Modeling of working bodies and the most important working conditions, as well as calculations were performed using the "APM Win Machine" package. As a result of the conducted research, it was found that large stresses are obtained at the place of attachment of the paw to the rack and reach 193.4 MPa, and with a decrease in the cross-sectional area of the rack, its strength characteristics correspondingly decreased to a value of 85.3 MPa.
