Nguyen, Thi Thu Hien. "Study of new exchangers for boron removal from water containing high concentration of boron". Thesis, Toulouse, INPT, 2017. http://www.theses.fr/2017INPT0138/document.
Texto completoBoron is an element, which is necessary as essential nutrient for living organisms, especially for plants where it is involved in cell wall composition. But boron excess can cause some problems on the development of plants (defoliation, decay and fall unripe fruits), of humans and animals such as nausea, diarrhoea, dermatitis, lethargy. Boron toxicity also changes blood composition, caused disorder in neurological, physical, intellectual development. Nowadays, due to the shortage of fresh water sources, seawater desalination has been becoming an alternative fresh water supply. However, the presence of boron in seawater is quite high (4.5 mg L–1, around 4.5 mM). Moreover, the increasing use of boron in industries and its discharge to the environment has led to the contamination of surface and ground waters. As the result, boron removal, in production of drinking water becomes very important. Therefore, the World health organization has recommended a guideline of 0.5 mg L–1 B in drinking water and a maximum limit of 0.3 mg L–1 B in fresh water used for irrigation. The objective of this thesis is to study the mechanisms of boron surface exchange on different materials versus time and at equilibrium depending on some physicochemical parameters such as pH, initial boron concentration, reaction time in order to find a new exchanger for boron removal. Boron removal was carried out by ion exchange process using 2 types of resins: Amberlite IRA 743, Diaion CRB 03 as boron selective resins with methylglucamine functions, and Ambersep 900-OH and Amberlite IRA 402 Cl as anionic exchange resins with ammonium functions. From batch studies, fast exchange between resin surface and liquid phase was observed with boron removal up to at least 96 % within 30 min for Amberlite IRA 743, Diaion CRB 03 and Ambersep 900- OH. The reaction between resin surface and boron solution reached equilibrium after 2 h for all the resins. The pseudo-second order kinetic model was used to well describe the sorption kinetic process of the resins. At equilibrium, the experimental results showed that the maximum adsorption was observed to be achieved at pH 8 for Ambersep 900- OH, pH 10 for Amberlite IRA 402 Cl and independent on pH range from 6 to 12 for the 2 boron selective resins Amberlite IRA 743 and Diaion CRB 03. At pH 8 and for boron concentrations < 20 mM, the Langmuir-type relationship was used to fit the experimental data for Amberlite IRA 743, Ambersep 900- OH and resin Diaion CRB 03. In the range of studied boron concentration, the boron sorption onto Amberlite IRA 402 Cl followed linear-type behaviour. At pH 8 and for boron concentrations < 20 mM, the sorption capacities are: 1, 0,7, 0,3 et 0,05 mmol g–1 for Diaion CRB 03, Amberlite IRA 743, Ambersep 900- OH and Amberlite IRA 402 Cl, respectively. Column experiments were performed with the anionic resin Ambersep 900-OH and the selective one Amberlite IRA 743 by studying both the influence of boron concentration and the residence time. For the selective resin, if the residence time decreases, the boron breakthrough is fast followed by a long tail. For larger residence time, local equilibrium seems to be assumed. Results are thus consistent with batch experimental data. For the anionic resin, the nonlinear behaviour is also confirmed. Moreover, column experiments showed a strong difference during desorption. To regenerate resins, acid and basic treatments are necessary for the selective resin although a basic solution is enough for the anionic resin. A more detailed study of mechanisms is in progress in order to build a exchange model for predicting boron fate. Finally, characterization of pectins was also performed. Its composition (sugar and boron content) and the viscosity of pectin solutions were quantified. Filtration experiments allowed testing the efficiency of such material to remove boron too

Texto completoA ship scheduling problem in optimization of water-borne crude oil transportation has been investigated. The classic optimization problem the most closely related to the problem at hand is the Multi-Vehicle-Pick-up-and-Delivery Problem with Time Windows (m-PDPTW). In addition to the basic characteristics of the m-PDPTW, the studied problem has an additional degree of freedom due to having pick-ups and deliveries that are not matched. This extra freedom gives new possibilities when creating effective heuristics when dealing with transportation problems. The studied problem has been presented in relation to carefully selected background literature. On this basis a proposed heuristic has been developed, and implemented using some already existing structures in the commercial decision support system TurboRouter. The studied problem is an industrial shipping problem, an operational mode where the shipper owns the cargo to be transported. No income is therefore made directly from transporting goods. Therefore the objective function chosen was net income, which in this mode is the same as minimizing the net expenses. A multi-start local search with pre-matching of pick-ups and deliveries heuristic was chosen based on an assessment of problem size, problem type, real life applicability and existing software. This heuristic consists of three main parts. First the pick-ups and deliveries are matched and merged in a pre-matching heuristic, and then a large number of initial solutions are generated by an insertion heuristic. The best initial solutions are then improved by a local search. Two strategies were developed for pre-matching and then tested. The one with the best test results was subsequently used in the heuristic. This multi-start local search with pre-matching of pick-ups and deliveries heuristic has been subject to rigorous testing and was compared to a single-start local search and multiple initial solutions heuristic. The solutions generated by the multi-start local search heuristic were superior compared to those of the other heuristics, but the computation time necessary was high and higher than those of the heuristics which it was compared to. This high computation time is partially believed to be a result of flexible data sets resulting in broad solution spaces. In addition some computationally expensive heuristics were deployed, increasing the computation time. In real life applications, finding a solution relatively quickly is of importance. Therefore the heuristic may need to be simplified and used on "tighter" data sets than some sets used in testing to be real life applicable.

Texto completoThis thesis achieves 3 years of PhD studies on “Atomic layer deposition (ALD) of boron nitride (BN)”. The aim of this PhD work is to adapt the polymer derived ceramics (PDCs) route to the ALD technique for h-BN thin film growth and elaboration of functional nanostructures. A novel two-step ammonia-free ALD process, which includes ALD deposition of polyborazine at low temperature (80 °C) from 2,4,6-trichloroborazine and hexamethyldisilazane followed by post heat treatment under controlled atmosphere, has been established. Conformal and homogeneous BN thin films have been deposited onto various substrates. The self-limitation of the reactions on flat substrates and the conformality of the films on structured substrates have been verified. Functional BN nanostructures have thus been fabricated using substrates or templates with different dimensionalities. In particular, their applications as protective coatings as well as filter and absorber to purify polluted water from organic/oil hav e been investigated. Finally, a second low temperature (85-150 °C) ALD process using tri(isopropylamine)borane and methylamine as precursors has preliminary been studied in order to confirm the adaptability of PDCs route to ALD technique. BN thin films have been grown onto flat substrate and it has been proven that tri(isopropylamino)borane vapor can infiltrate into electrospun polyacrylonitrile fibers.This work was carried out at University of Lyon and financially supported by the National Research Agency (project n° ANR-16-CE08-0021-01)

Texto completoOcean acidification is caused by the absorption of rising atmospheric CO2 by seawater andrepresents a major environmental issue. Since the beginning of the industrial era, seawater pH hasdecreased by 0.1 pH units and is already threatening calcifying organisms. Boron isotopes (11B) haveproved to be a powerful geochemical tool for the reconstruction of pH variations, but has not yet beenapplied to deep-sea corals (DSC). Accurate and precise measurements of boron isotopes in coralsand seawaters were performed in order to measure small pH variations.The technique of pH reconstruction based on boron isotopes (pH-11B) was used on two specimens of the DSC Madrepora oculata and Lophelia pertusa collected alive in the Norwegian Sea and spanning an age of 40 (3) and 67 (3) years, respectively. Acidification rates were calculated by applying a new pH-11B calibration obtained from the geochemical analysis M. oculata and L. pertusa samples cultured under different pCO2 conditions. The contribution of a biological-related vital effect on d11B was observed at macrometer scale, and a correction was finally suggested based on oxygen and carbon isotopes. Overall, the coral δ 11B-based reconstructions show a pH decrease in the Norwegian Sea since the 1940s, which seems to be related to the local hydrodynamics. The pH-11B technique was also applied to fossil DSC fragments from two “on-mound sediment cores” retrieved in the Siculo-Tunisian Strait with the aim to reconstruct the pH during the Last Glacial Maximum and the Holocene periods. Finally, well-preserved limestone samples from the stratigraphic sequence Nama (551-543 Ma) in Namibia were investigated for 11B to study the pH variations at the beginning of the Cambrian evolutive radiation

Cortical bone fragility increases with age, therapeutic drug use and disease states. Clinically, bone fragility is evaluated by assessment of bone mineral density (BMD); however, studies have shown that other factors such as bone architecture, cell turnover and tissue composition influence bone quality. There is growing evidence that age related changes in bone water associated with collagen and/or mineral have a direct impact on bone mechanical competence and structural integrity. Understanding these compositional changes will aid in improved diagnose and prediction of fractures. Magnetic resonance imaging (MRI) is used to evaluate bone water, but this modality is limited in spatial resolution and is still being developed. Although still in the experimental stage, vibrational spectroscopy in the near infrared region (NIR) also known as near infrared spectroscopy (NIRS) is a nondestructive modality that can spatially evaluate alterations of bone composition. NIRS is a unique nondestructive technique that produces a signature spectrum by penetrating high frequency (4000-12,000 cm-1) non-ionizing radiation into material. NIRS permits a depth of penetration from millimeters to centimeters, dependent on frequency (wavelength). NIRS is very sensitive to water and can be used to provide molecular information of water related to collagen and mineral in bone samples. To date, definitive information on which NIR absorbances are linked to collagen or mineral bound water have not been identified. The overarching hypothesis is that water associated with collagen and/or mineral can be identified using NIRS and will serve as a biomarker for bone fragility in future preclinical studies. This will be achieved with the following three aims: First, to develop a method to image human cortical bone tissue using NIRS; second, to identify NIRS absorbances of water bound with mineral and collagen in bone; and finally, the third aim, to correlate the NIRS-derived water content in human cortical bone to structural properties determined by micro-computed tomography (micro-CT). Together these studies will establish the NIRS technique as a powerful tool to screen and monitor aging and diseased tissues in preclinical studies.

Maleinized fatty acids were then introduced, and the reaction was carried out at 90oC for 10 hours. 1,4-dioxane was used for the removal of the water, which forms as the byproduct. Then the driers were added. The carboxylic groups of the maleinized fatty acid were neutralized by morpholine and the product was dispersed in water. The varnish was applied on test panels and left for air-drying for 24 hours and then baked at 140°
C for 5 hours. The free epoxy content was determined by pyridinium-chloride titration and it was seen that all the epoxy groups reacted. Also, produced fatty acid was characterized by FTIR spectroscopy and maleinized fatty acid was characterized by H-NMR and FTIR spectroscopy. Hardness, bending, impact resistance, gloss, and abrasion resistance tests were carried out on hardened varnish specimens. The samples generally showed good mechanical and physical properties. While the baking time was increased the hardness of product increased. Samples showed superior impact resistance, gloss, and flexibility.

Texto completoHemos investigado los principales condicionantes de los paseos costeros como elementos de protección del borde de agua y como elementos que se integran en el medio natural, basándonos en el estudio sistemático de diversas experiencias ya realizadas, para desarrollar el análisis de este tipo de espacio público asociado al ejercicio de la proyectación arquitectónica. Este tipo de espacio complejo, concebido desde distintos aspectos ―algunos fundamentales para su realización, como el económico―, en este análisis será abordado desde el punto de vista morfológico, a partir del análisis visual y del análisis gráfico.
En la investigación se da énfasis al paseo costero como protagonista principal en la tarea de la ordenación del borde costero y como el elemento capaz de rematar dignamente las áreas urbanas y configurar la fachada de la ciudad junto al mar. Hemos buscado reconocer las relaciones entre el borde y la ciudad que establecen la idea de unión, definir cuáles son los condicionantes físicos que configuran la delimitación urbana y la relación con los elementos urbanos de la ciudad. A través de diversos proyectos analizados establecemos algunos parámetros respecto a la calidad visual a nivel urbano (texturas, volúmenes y colores) y a nivel del observador (suelo, fachada, arbolado, mobiliario urbano y elementos especiales).
El punto de partida es la construcción de un esquema metodológico que ha permitido profundizar en las relaciones entre las soluciones estudiadas y un caso real al cual podría aplicarse. A partir de este momento entramos en un área bastante cercana a la autora, que es el actual estado de la zona costera de la ciudad de Porto Alegre. Se estudia un tramo bastante central, de siete kilómetros, donde fue construida a poco más de diez años una avenida junto a la costa como una vía para intentar resolver el problema del tráfico viario, cuando, a partir de este momento, la ciudad redescubre la costa que estaba olvidada. Actualmente esta zona presenta sólo algunas intervenciones puntuales y mantiene sus características naturales. Este trabajo ha buscado reconocer los diferentes elementos de este tipo de zona que requiere una teoría propia donde se describan tipos universales aplicables a la definición del borde costero. Hemos pretendido establecer una relación de indicadores y sugerencias que permitan reflexionar sobre el paseo desde su uso urbano y su relación con el ámbito natural.
La tesis busca comprender con qué herramientas de análisis se puede lograr una mejor comprensión y aproximación al espacio construido y cómo este estudio puede auxiliar a la hora de establecer directrices para crear un espacio público similar. Finalmente, el trabajo es un análisis del borde costero como espacio público de excepción dentro de la ciudad. A través de la observación de valores percibidos en paseos existentes dentro de España y dos casos significativos brasileños se ha buscado determinar los principales elementos de formación de este tipo de área. Partiendo de este punto, evaluamos el caso de Porto Alegre cuya zona costera, junto al centro de la ciudad, necesita una intervención. Basados en las conclusiones de la investigación, proponemos directrices para este caso específico.
This essay intends to unveil the relationship between the boundaries of the sea and the urban network with regard to its structure, the value of the promenade in connection with the city to define a collective identity.
When the city grows, it losses, develops, discovers or bumps into new identities which give it another value; the promenade is a structure which carries a valuable meaning to the local identity and it has to fit in with the city's structure. This essay intends to identify such values by turning them into images and graphs.
We did a research into the determining factors of the promenade as a key protection of the seaside and as an element which blends with nature. Such conclusions are based on a wide range of different experiences which helped us to get a complete insight into this architectural element. One of the key factors to analyse this complex space is the economic viewpoint, however, we are going to analyse it from a morphological point of view together with a visual and graphic analysis.
This research highlights the promenade as a key weapon in the coast planning as well as an outline against the urban areas which contributes to the city's façade. We intended to identify the link between the seashore and the city, and at the same time to define the physical elements which set the urban limits and their relationship. The different projects analysed lead to some conclusions concerning the quality of the urban landscape (texture, volume, colours) and the observer's feedback (ground, façade, woodland, street furniture, special elements).
The drawing of a methodological sketch is the starting point to deepen into the relationships between the solutions studied and a real case to which it could be applied.
From this moment onwards we get into the current condition of the coastal area of Porto Alegre.
The scope of the study covers a stretch of seven kilometres. There, an avenue was built next to the coast within ten years or so in an effort to solve road traffic problems. At that moment, the city rediscovers the coast which had been completely forgotten.
At present, this area maintains its natural features on the whole. This essay tries to identify the range of different elements in the area to set them as an example so that they can be applied to the definition of "seashore". We made a list of signs and suggestions to think about the promenade, its urban use and its connection with the environment.
The thesis looks for the necessary tools to achieve a better understanding of the built belt. It might help to build up guidelines when the right time comes to create a new and similar public area.
To sum up, the essay is an analysis of the seashore looked on as an exceptional public area in the city. We paid attention to similar features of existing promenades in Spain and Brasil (two cases) to establish the reasons why such areas got created. Working on this principle, we reached the conclusion that Porto Alegre needs refurbishing. Based on the conclusions of the research we put forward some guidelines for this particular case.

Texto completoThe research presented in this thesis examines the behavioural responses of an indigenous crayfish (C. tenuimanus) and an invasive crayfish (C. albidus) to waterborne odours derived from food, alarm sources and finfish predators. This study was undertaken to assist in the understanding of predatory and competitive interactions between indigenous and non-indigenous crayfish and fish predators, with particular relevance to Western Australia. Predation and competition are major forces influencing community structure in ecosystems; therefore knowledge of competitive and predatory interactions will be of benefit when considering future translocation policies.
Behavioural trials were conducted in two culture systems (54 L aquaria and a 70,000 L mesocosm), where marron and yabbies were exposed to a range of water-borne odours from finfish predators (silver perch and Murray cod), with and without competition from conspecific and heterospecific crayfish. A number of variables likely to influence crayfish behaviour were investigated: strength of chemical odour; crayfish size, gender, diurnal and nocturnal activity patterns; predator size; prior-residence; suitable habitat/shelter; and feed availability.
A key innovation in this research was the high replication in the aquarium-based observation trials using a Latin Cube design, which resulted in greater statistical strength and lower variability. More importantly, this research deviated from the tradition of exclusively using the ‘individual crayfish’ approach for odour-detection experiments and tested these results in a 70,000 L communal observation tank. This was an important development in crayfish behavioural experimentation, particularly as several key findings from the individual crayfish approach were confirmed in a multi-species environment.
Results from this study supported the hypothesis that invasive crayfish species make more appropriate use of a wider range of information about their environment than native crayfish species. Yabbies were found to possess behavioural characteristics not present in marron, such as clearer behavioural modifications to food and heterospecific odour, and cautionary behaviour in the presence of odour from a finfish predator. During simulated daylight conditions, marron displayed behaviours conducive to predation that were not present in yabbies, including less time spent in shelter and more time spent in locomotory activity. However, during specialised night-time observational studies developed during this research, these differences were not evident. This would not seem to be an unusual result, given that crayfish naturally forage at night and become more active; however, it may have important implications for future behavioural studies of crayfish, indicating a bias associated with day-time approaches. Crayfish size also played a role in behavioural modifications to water-borne odours. Larger marron displayed clearer changes in behaviour and were more responsive to heterospecific alarm odour than juveniles. Furthermore, juveniles of both species were more active than adults and sub-adults.
The expansion of the yabby population into Western Australian habitats occupied by marron has been facilitated through translocation for aquaculture, and biological characteristics of the species, some of which are typical of other invasive crayfish species including: tolerance of a variety of conditions; rapid growth; early sexual maturity; burrowing to escape drought and predation; capable of multiple spawns in a growth season; and aggressiveness. Another characteristic of invasive crayfish species also shared by yabbies, as supported by the results of this study, is high behavioural plasticity.
Although marron do not share the same level of behavioural plasticity found in yabbies, their larger body size increases their success in competitive interactions. The comparatively smaller body size of yabbies may be the major factor limiting their population expansion in the presence of marron, especially in water-bodies where shelter is a limited resource.
Marron are an important endemic species in Western Australia, but their conservation is threatened by competition and predation from exotic species. The research presented in this thesis indicates that invasive yabbies are more receptive to chemical stimuli and better equipped to respond to predation risk than marron. This information will be of benefit when considering future translocation policy in Western Australia and highlights the need for a cautious approach to species introductions.

Texto completoENGLISH ABSTRACT: Water-borne infections have been a menace in many countries around the globe, claiming millions of lives. Cholera in particular has spread to all continents and now on its seventh epidemic. Although control measures have been continually developed through sanitation, vaccination and rehydration, the infection still devastates populations whenever there is an outbreak. In this research work, mathematical models for cholera transmission dynamics with focus on the impact of sanitation and hygiene, metapopulation spread, optimal control and biological control using a bacteriophage specific for pathogenic Vibrio cholerae are constructed and analysed. Vital analyses for the models are precisely given as well as numerical results depicting long term behaviour and the evolution of populations over time. The results of our analysis indicate that; improved sanitation and hand-hygiene are vital in reducing cholera infections; the spread of disease across metapopulations characterised by exchange of individuals and no cross community infection is associated with synchronous fluctuation of populations in both adjacent communities; during control of cholera, the control measures/efforts ought to be optimal especially at the beginning of the epidemic where the outbreak is often explosive in nature; and biological control if well implemented would avert many potential infections by lowering the concentration of pathogenic vibrios in the aquatic environment to values lower than the infectious dose.
AFRIKAANSE OPSOMMING: Water-infeksies is ’n bedreiging in baie lande regoor die wêreld en eis miljoene lewens. Cholera in die besonder, het op sy sewende epidemie na alle kontinente versprei. Hoewel beheermaatreëls voortdurend ontwikkel word deur middel van higiëne, inentings en rehidrasie, vernietig die infeksie steeds bevolkings wanneer daar ’n uitbraak voorkom. In hierdie navorsingswerk, word wiskundige modelle vir cholera-oordrag dinamika met die fokus op die impak van higiëne, metabevolking verspreiding, optimale beheer en biologiese beheer met behulp van ’n bakteriofaag spesifiek vir patogene Vibrio cholerae gebou en ontleed. Noodsaaklike ontledings vir die modelle is gegee sowel as numeriese resultate wat die langtermyn gedrag uitbeeld en die ontwikkeling van die bevolking oor tyd. Die resultate van ons ontleding dui daarop dat; verbeterde higiëne is noodsaaklik in die vermindering van cholera infeksies; die verspreiding van die siekte oor metapopulaties gekenmerk deur die uitruil van individue en geen kruis gemeenskap infeksie wat verband houmet sinchrone skommeling van bevolkings in beide aangrensende gemeenskappe; tydens die beheer van cholera,behoort die beheermaatreëls/pogings optimaal te wees veral aan die begin van die epidemie waar die uitbreking dikwels plofbaar in die natuur is; en biologiese beheer, indien dit goed geïmplementeer word, kan baie potensiële infeksies voorkom deur ’n vermindering in die konsentrasie van patogene vibrio in die water tot waardes laer as die aansteeklike dosis.
