For highly concentrated ammonia effluents (containing 300 to 1000 mg NH4 +-N. L-1), partial nitrification can be used to optimize the treatment process. The most challenging aspect is to maintain a long term stable nitrite accumulation. A sequencing batch reactor allows a total conversion of ammonia to nitrite. The main control parameters are pH, applied load and cycle duration time (aerated periods). Process control, based on on-line oxygen uptake rate, allowed to optimize the process cycle duration time, whatever was the influent ammonia concentration or the biological activity. With this system, a high loading was reached (2 kg NH4 +-N. M-3. J-1), with complete removal of ammonia and a maximal conversion of nitrogen into nitrite. The main biological mechanism was the inhibition of nitrite-oxidizing bacteria by free ammonia (NH3). A mathematical model was developed, calibrated and validated for the description of the two-step nitrification. The effluent used in this work contained a high phosphate concentration and a low COD/N ratio, and produced a sludge enriched in mineral matter and autotrophic bacteria. The concomitant precipitation of phosphorus showed a minimal phosphorus removal efficiency of 40%, reaching 90% when the ammonium concentration in the reactor was high. This adaptive process control offers a promising way to simultaneously treat nitrogen and phosphorus in the same reactor, minimizing energy needs and favoring the possible valorisation of the phosphorus present in the sludge

Boujellal-Benazouz, Louisa. "Alimentation en eau potable de la ville de Constantine." Nancy 2, 1991. http://www.theses.fr/1991NAN21018.
The problem of water is really acute in all the Algerian cities that is why the theme about the supply of potable water for the city of Constantine has been chose. For this it was necessary to introduce Constantine taking into account its climate, its relief and history, to come afterward to the inventory of the situation of the different underground reserves because of the lack of water, and the unsteady relief of the town, the distribution of water is undertaken with difficulty: one day out of two, during 2 hours maximum, without forgetting the problem faced by high buildings. The norms stated by the OMS (world health organization) are 1501 inhabitant day, are far from being reached and after the study of some statistics, it has been estimated that Constantine will always face supply difficulties and remains dependant on the discovery of new springs the system of making water healthier, which seems to be satisfactory, is divised into three categories: unitary, separatist and inexistent. Spoilt water will be collected and treated by the future purification station in order to irrigate the agricultural fields of hamma. This will allow Constantine to benefit from an appreciable volume of potable water

La présente étude s’est donnée pour objectif d’actualiser les prédicteurs de la saine alimentation, chez les Canadiens âgés de 18 ans et plus avec des données récentes (Enquête sur la Santé dans les Collectivités Canadiennes (ESCC)-Nutrition 2015) et de vérifier l’effet de nouvelles variables. Ce, parce que les études menées jusque-là pour évaluer les déterminants de la saine alimentation sont des études anciennes ou lorsqu’elles sont récentes elles sont quand même basées sur les données de 2004. Dans ce cadre, nous avons évalué la qualité de l’alimentation avec l’indice de saine alimentation, version 2005 adaptée au contexte canadien (HEI-C2005), puis nous avons mené une régression linéaire multiple avec comme variables explicatives des facteurs socioéconomiques, démographiques, l’état de santé, le niveau d’activité physique et le bien-être général perçu. Nos résultats montrent qu’actuellement, la qualité de l’alimentation de la plupart des Canadiens doit être améliorée (un indice moyen de 68/100 avec un écart-type de 12, sachant qu’une valeur de 80/100 ou plus est le seuil d’une saine alimentation). Toutefois, il y a eu une amélioration par rapport à 2004 (indice moyen de 50,2/100). En ce qui concerne les prédicteurs, l’effet connu des variables classiques (âge, genre, éducation, bien-être perçu, revenu, origine ethnique et niveau d’activité physique) n’a pas changé. Concernant ce qui n’a pas encore été vérifié dans les études précédentes, nos résultats démontrent que l’insécurité alimentaire et le prix des légumes ont un effet négatif sur la qualité de l’alimentation Les personnes diabétiques et les personnes ne souffrant pas de cancer ont une alimentation plus saine que les non-diabétiques et les personnes souffrant de cancer. Aussi, nos résultats montrent que le prix des fruits et le milieu de résidence n’ont pas d’effet sur la qualité de l’alimentation.
The objective of this study is to update the predictors of healthy eating for adult Canadians with recent data (Canadian Community Health Survey (CCHS) -Nutrition 2015) and check the effect of new variables. This, because studies conducted to date to assess the determinants of healthy eating are either old studies or recent ones are still based on 2004 data. In this context, we evaluated the quality of the diet with the healthy eating index, 2005 version adapted to the Canadian context (HEI-C2005), then we carried out a multiple linear regression with as variables socioeconomic and demographic factors, health, level of physical activity and perceived general well-being. Our results show that currently, the diet quality of most Canadians needs to be improved (an average index of 68/100 with a standard deviation of 12, knowing that a value of 80/100 or more is the threshold of a healthy diet). However, there has been an improvement over 2004 (average index of 50,2 / 100). For predictors, the known effect of the classic variables (age, gender, education, well-being, income, ethnicity and level of physical activity) has not changed. Regarding what has not been verified in previous studies, our results show that food insecurity and vegetable prices have a negative effect on the diet quality. People with diabetes and people who don’t have cancer have a healthier diet than non-diabetics and people with cancer. Also, our results show that the price of fruits and the residence area have no effect on the diet quality

Seigneuret, Gary. "Analyse et Optimisation de télé-alimentation pour systèmes RFID UHF." Thesis, Aix-Marseille 1, 2011. http://www.theses.fr/2011AIX10141/document.
The passive radio frequency identification tags (RFID) systems communicate with a remote power supply thanks to electromagnetic waves. Increasingly present in our environment (biometric passport, inventory management), they present the advantage to have an almost infinite lifetime, and consume energy only when they are solicited. Moreover, because it is a wireless way to communicate, it is possible to use these systems places inaccessible to optical drives type bar code. However, the range of such systems is limited by the efficiency of the recovery of energy from waves. In this context, increasing the range of RFID tags, especially for logistics applications is essential.In this these, different ways to increase the range are studied. The first part focuses on the reduction of losses on the rectifying circuitry thanks to layout optimization. An high performances architecture with transistor biased is then proposed. Finally, the impact of backscattering and impedance matching on the energy recovery are studied and improved

The protection and the vectorization of active, food and pharmaceutical molecules, require separating them from their environment by entrapping them in structured matrices able to release them at the precise place and the quite time. When these encapsulation systems are based on dry emulsions, the control of the matrices requires the knowledge of both the properties of the interfacial membranes and those of the drying matrix. The characterization, of the interfacial properties of pea proteins, in presence and absence of pectin, an anionic polyelectrolyte, allows the study of the interactions proteins/pectin at O/W interfaces and their effect on the emulsion stability during spray-drying process. The study of the effect of the properties of the dehydration matrix, maltodextrins, makes it possible to link their interactions with water to the encapsulation efficiency of dry emulsions. The molecular investigation highlights the role of pectin in the stabilization of the secondary structure of pea globulins during drying, which results in a better protection of the encapsulated active molecule. Lastly, the analysis of the release kinetics of a volatile molecule makes it possible to evaluate the barrier properties of the interfacial layers and to identify the release mechanism. The whole of this work at various scales makes it possible to contribute to the understanding of the various mechanisms implied in the emulsion stabilization by multi-layered interfaces containing proteins/polysaccharides, their resistance to spray-drying and finally their capacity to protect fragile compounds

Building materials are porous materials, and therefore very sensitive to water. Due to variable hermodynamical ambient conditions, processes of energy and mass transfers between the ambient air and the material occur. These exchanges lead to important modification of their thermal properties and their durability. For instance, measurements of the thermal conductivity of Hemp Lime Concrete, placed in climatic chamber in which the relative humidity is 75%, show a variation of 30%. This PhD Thesis deals with the case of three porous buildin materials: Aerated Autoclaved Concrete (AAC), Hemp Lime Concrete (HLC) and Vertically Perforated Brick (VPB). The hygrothermal behaviour of these materials is studied with the experimental set-up called cell of exchange. This cell consists of test walls which are place between a climatic box and the laboratory. The scope of this experimental work is to create gradients of temperature and of relative humidity through the sample. So, the study aims to measure and characterise heat and mass flows in these materials. Ln a second part, simulation are performed to design, expiain and interpret the experimental results. They are done in COMSOL Multiphysics. Ln a first approach, only the heat equation in 1 D has been implemented in the toolbox. Comparisons between experimental and theoretical results gives us the therm properties of tested materials (ʎ,ρ,c,hs et a). The numerical modeling approach shows that, contrary to AAC or VPB, HLC involves a complex interaction between heat transport and mass transfer through the material. So, simulations on HLC are investigated through the problematic of phase change materials

Coprolites have long been used in palynology for paleoenvironments reconstruction. They also are an important source of information on the DNA of the producing species and its diet. Using numerous archeological samples from several caves, including the Chauvet-Pont d’Arc cave, we studied coprolites for two species: the wolf, Canis lupus and the cave hyena, Crocuta crocuta spelaea.Using a canid coprolite from the Chauvet cave, dated back to 34 500 years, we obtained a complete mitochondrial genome sequence. Phylogenetic analyses highlight a maternal lineage that positions outside the diversity of extant dogs and wolfs. Then, analyzes conducted on the nuclear genes showed that the Chauvet canis lupus specimen does not display obvious indication of domestication. Analysing the coprolite for other species to indicate the diet of this specimen, we detected cave bear (Ursus spelaeus) DNA sequences.Second, using many cave hyena coprolites, a flexible diet consisting of large as well as small animals was demonstrated for this extinct carnivore. Focusing the analysis on a coprolite samples that contained large amounts of bovine DNA, we obtained for the first time a complete mitochondrial genome sequence for the extinct European forest bison, Bison schoetensacki. In parallel, a bone sample for the extinct steppe bison provided the first complete mitochondrial genome sequence for Bison priscus. These two genome sequences shed new lights on the phylogeny of Bovinae

In france, local communities, known as + communes ; have a local mission of providing public services. These + communes ; are, by the law, responsible for producing, distributing drinking water and the collect and treatment of wastewater. This activity (largely a natural monopoly) is qualified as industrial and commercial local public service. Furthermore, the french water utilities are required to be financially self-sufficient. Rate-setting varies across regions and local territories due to a variety of organizational figures of services and availability of water resources. Current french water services pricing practices are for no doubt inefficient : they are based on average utility costs determined using historical accounting costs rather than the effective optimal economic costs, adjusted for reasonably predictable changes. They do not consider factors such as the cyclicity of demands, the time-of-use, heterogeneity types of consumers and the real value of water resources (scarcity). The purpose of our work is to analyze the legal and institutional framework of water and wastewater public services, legal aspects, contracts of delegation, and competition, and to determine the optimal peak-load and nonlinear pricing rules for water and wastewater services which will provide important guidance in the design of efficient water rates and in the development of different water utilities planning strategies. We present the economic forms of regulation applied to privatized public utilities, and the optimal regulation which can be the economic regulation framework for the french water services delegation

Hypertension is the most prevalent chronic disease in the world and lifestyle behaviors, namely adherence to a healthy diet (rich in fruits and vegetables and with reduced consumption of salt), maintain of normal weight, regular physical activity and limitation of alcohol, for its prevention and control are recommended within worldwide guidelines. Our aim was to study the relationship between those recommended lifestyle behaviors and first blood pressure level and second risk of incident hypertension, through cross-sectional and prospective analyses using data from the NutriNet-Santé study, a French web-based cohort. Our results reported significant associations between body mass index, fruits and vegetables and alcohol consumption, and physical activity; confirmed the association of several nutritional factors and incident hypertension and highlighted that adopting a global healthy diet could strongly contribute to the prevention of hypertension. Moreover, adhere to all the recommended lifestyle behaviors could reduce the hypertension risk of half or at least delay the new onsets of hypertension

The nature, concentration, and distribution of particles were evaluated in a large water distribution system, both for suspended matter and deposits, to better evaluate their impact on water quality. A constant flux of particles is found penetrating the distribution system from the treatment plant. Concentrations are low (25-50 µg/L dry matter), and mainly consist in organic and biological material. After one year, such concentrations represent on average 1 ton of particles introduced in the network. The transport of water in the network produces particles since suspended matter concentration slightly increases (30-130 µg/L), and loose deposits accumulate in pipes and reservoirs. These deposits are mostly minerais (insolubles, hydroxides, carbonates) resulting not only from the sedimentation of particulate matter, but also probably from the precipitation/flocculation of dissolved and colloïdal material, and from the corrosion of the surfaces in contact with water. Organic matter is a minority fraction in deposits (less than 20% on average), but corresponds to concentrations about 1000 times higher than in water, resulting in the accumulation of biomass (2. 5 108 culturable bacteria per gram), leading in some cases to the presence of macro-invertebrates in deposits. By the way, deposits are forming ecosystems which can act as a refuge versus disinfectants carried with water, since organic compounds accumulated in deposits have a high reducing capacity. The accumulation of organic matter and bacteria in deposits does not result from the sedimentation of suspended particles, but merely from the biological growth on dissolved organic matter. The control of microbial problems resulting from the resuspension of deposits in the water phase can thus mainly be achieved by reducing the quantity of dissolved organic matter introduced in the system

The role of the adsorption was studied in the heterogeneous catalytic oxidation of the organic molecule and hydrogen sulfide with the dispersed support metal oxide. The physical and superficial properties was measured before and after dispersion of metal oxide. We have studied the catalyst behavior with the natural water mineraI ions. The knowledge of the superficial properties of metal oxide or support and their affinities for mineraI ions has allowed for clarifying their role in the adsorption of four organic molecules. It has also allowed for knowing the adsorption mecanisms of the salicylate (humic matter model) on two supports. Then, the role of the adsorption in catalytic oxidation was estimated with ozonation experimentations. It appears that the catalytic oxidation is happening whether the molecule is adsorbed or not. The mecanisrns of catalytic oxidation are similar to the ones of homogeneous oxidation and therefore pH sensitive. The metal oxide and supports have adsorbed ozone and have participated at its initial decomposition in presence of hydroxile or peroxide ions. The kinetic of this reaction is slow and the adsorption or direct oxidation are possible. The study of catalytic oxidation of hydrogen sulfide shows three adsorption-oxidation forms. Two forms are easily reversible and represent the major adsorbed sulfur for low values of concentration. The most stable form, metallic sulfide, corresponds at a weak poisonning of the metal oxide. The catalyst support is inert in regards to hydrogen sulfur when the metal oxide is present

Water is an exceptional raw material as far as it is essential for people, animais and vegetables. Ifs considered for a long time as an unlimited plentiful resource. Some people consider it free or almost free. Water is one of the keys of sustainable development; it presents an important dimensional device for the social, economical and environmental development. Water is essential for human health and for that reason it satisfy human essential needs. Ln our research, we find that I?ollution is presented everywhere. Some developed or none developed countries, cares enough about the quality of water and controllers' pollution. Agriculture is the main reason responsible for pollution, more than the industry and municipalities. Ln sorne countries farmers use, fertilizers, pesticides, contaminated ground-water and superficial water. Agriculture remains the principle source for water pollution but the amount of factories and municipalities' garbage has increased in the last years. We believe that there are two hundred to four hundred chemical products found in water. Ln our research ifs composed of two axes. The first is theoretical, and the second is empirical. The primary one is divided into two chapters: ln. The first, it will concern sustainable development, to study the relation between economy and environ ment, concept of development, influence of climatic changes and inform the international politics. We took the example of Corsica to show that the nearness of watercourses for populations bordering the street has an impact on the quality of water in the same capacity as nearness of porcine animal. Data come in the form of qualitative evaluations allocated by experts. A model of logique floue was used to establish a synthesis of data and define a quality indication of the water taking its stocks interval [0, 1]. An econometric analysis allowed then to update the determiners of the quality of water

The particularity of the early chemosensory experience of premature newborns poses the question of the repercussions this could have on the development of feeding behaviors of preterm infants, both in the short-term, during the acquisition of sucking skills, and in the long-term during dietary diversification. Three groups of newborn premature babies who where exposed to three different chemosensory experiences associated with active milk consumption [in increasing order of chemosensory experience – formula milk, formula milk and odors (carrot, cauliflower, grilled chicken, banana, peach) and maternal milk] were monitored during the transition from passive to active feeding then from the age of 4 months until two months after dietary diversification. Analysis was carried out of infant's odor reactivity, the quality of non-nutritive sucking, their food intake at the time of transition from passive to active feeding, their pleasure during their first tries of non milk foods as well as their feeding behaviors as reported by their parents. The research has not resulted in conclusions regarding the effect of the type of chemosensory experience on odor reactivity, the quality of non-nutritive sucking and feeling behaviors during weaning. Nevertheless, it highlights a positive effect of the type of chemosensory experience on mouth opzening upon nipple approach as well as nutritive sucking performances assessed on efficiency, proficiency and overall consumption. These results highlight the influence of the type of early chemosensory experience on the application of short term feeding behaviors. Taking this into consideration during developmental care should be approved in order to encourage the acquisition of nutritive sucking, thereby allowing preterm infants to be taken home early

With traditional desalination plants, operative by phase shift (vapour compression mechanical, multi-flash, multiple effects. . . ) Two major problems arise: the rejection of a large quantity of water non-satured in salt and the build up of salt in all the installation components. The traditional solution to overcome these problems consists in introducing chemical substances for the pre-treatment of salted water. The present thesis proposes through analysis multipurpose system desalination, that a regulation on the rate of feed could be an alternative method to reduce this water loss, and consequently the production cost. This analysis allows us to evaluate energies brought into the system and the exergetical losses. A modeling in dynamical mode will follow this analysis. A comparison with a system not controlled makes it possible to evaluate the performances of the system. Finally a feasibility study gives an idea on its implementation

The management of a groundwater resource used for irrigation is a phenomenon that depends on several factors and concerning various actors (users and manager). Moreover, the resource can be subject to droughts. In this case, the management of the resource becomes a more complex problem. Adaptation to droughts is important because they can have significant impacts on agriculturalactivity and on the water table of the resource. This adaptation hinges crucially on the information available to the manager and the resource users. In chapters 2 and 3, we analyze the impact of an hydrological drought on the optimal management of the resource, before and after its arrival. In particular, in chapter 2, we show how the manager can adapt as good as possible to this drought according to the nature of information he has. In chapter 3, we are show that taking into account strategic and dynamic interactions between the users of the ressource leads to less efficient resource use. We apply models of chapters 2 and 3 to the aquifer Western La Mancha, in Spain. In chapter 4, we study the impact of an agronomic drought on the optimal management of a farm in the area of Central Beauce, in France. We take into account hydrological, agronomic and economic informations. In particular, we analyze the impact of a dry period on the annual benefits of the farm and on the groundwater resource level. Furthermore, we study optimal strategic behavior of farmers in a dry year, whether they are subject to water restrictions or not. We show that a regulation policy is necessary to avoid the overexploitation of the ressource in a dry year

Soybean (Glycine max. (L.) Merrill) is a leguminous crop that does not require nitrogen fertilizer, which is grown with few pesticides, has a very good greenhouse gas balance and provides protein-rich seeds (38 to 42% of the dry matter on average). Water is the main limiting factor in soybean production (Merrien, 1994), particularly for cropping systems in southwestern France facing the context of climate change (more frequent droughts) and increasing pressure on the use of water resources for irrigation. A water deficit imposed during the seed filling period is particularly detrimental to soybean yield (Pardo et al., 2015). Facing diversified and diverse production contexts constrained by water, the characteristics of the variety are becoming increasingly important (Maury et al. 2015). The approach implemented in the thesis is based on three wellconnected approaches: (i) analysis of key physiological processes under controlled conditions and varietal phenotyping (i.e. phenology response to temperature and photoperiod over a wide varietal range), (ii) evaluation of genotype-environment-crop management interactions (GEMI) for field reference varieties with different planting dates and water management, and (iii) dynamic modelling of GEMI. The response of 10 genotypes to progressive soil drying was evaluated in 2017 and 2018 on the Heliaphen outdoor platform. The germination response to temperature was studied to characterize the cardinal temperatures of the genotypes tested. It was completed by a pot experiment on the Heliaphen platform, involving several planting dates from March to July, to study the response of these same genotypes to photoperiod and temperature. The information collected during these two experiments made it possible to develop and calibrate a simplified phenology algorithm (SPA). Field experiments combining different planting dates and water managements were carried out as part of the Sojamip project (2010-2014) and the thesis (2017- 2018). All these data, produced in the Occitanie region (from Toulouse to Béziers), made it possible to calibrate and evaluate the STICS model for Soybean. The model could be used to perform a posteriori diagnosis of the conditions encountered by genotypes in the field. Our results show the diversity of responses of soybean genotypes grown in Europe to photoperiod, temperature and water stress. The satisfactory performance of the phenology algorithm made it possible to explore the cultivation areas of the varieties studied under current and future climates in France. The study of the response to water stress made it possible to identify genotypes that maintain their stomatal functioning for a longer or shorter period of time ("conservative" vs "efficient" types). The performance of the STICS model was satisfactory, except for the simulation of the yield and characteristics of the grain (oil, nitrogen), highlighting the need for an adaptation of the formalisms for soybean. The model was able to be used to diagnose experimental conditions in the field through the calculation of stress indices. This diagnosis made it possible to show the interest of early planting to delay the soybean cycle and thus reduce the intensity and duration of water stress. In conclusion, we have shown that the integrated study of GEMIs is necessary to understand the situations that soybean plants have faced. However, it will be necessary to continue the exploration process using STICS to be able to test many cultural practices and varietal traits. This perspective will make it possible to propose soybean ideotypes for waterconstrained environments in France and possibly Europe

This thesis approaches the problems of the tariffing of the water services in two distinct parts which correspond to the two principal elements of the water invoice: The first part relates to the analysis of the French water Agencies taxes and their role of financing water infrastructures. This is an evaluation of the financial redistribution system managed by the water Agencies. From the point of view of their financial function, impact of the collected taxes (via the water bill) and of subsidies granted finally finance the conformity of the infrastructures of water utilities. From the point of view of their function of incentive to the modification of polluting behaviours, the analysis of the system effectiveness of tax and subsidy must integrate the system of standards of emissions. The second part seeks to quantify the impact of the determinants of the price of the water services using econometric models applied to a database describing the drinking water utilities in 1724 communes of the Seine basin. This model proposes to measure the impact of the management model (public or private) and of the mode of organization (communal or inter-commune level) on the final utility price
