Les espaces intertidaux correspondent à des estrans soumis à un régime de marée montrant un certain marnage. Il s’agit d’étendues basses constituées d’alluvions récentes, situées à proximité des mers à marée et envahies par les eaux lors des marées hautes. Les espaces intertidaux au nord du Vietnam sont sous l’influence de la mousson associé à un régime de marée diurne. Ils s’étendent sur environ 350 km le long de la côte. Le sud de la zone d’étude est marqué par le delta du fleuve Rouge et le fleuve Thai Binh qui apportent une grande quantité de sédiments, entraînant des estrans à dominante vaseuse ou vaso-silteuse. Le centre de la zone d’étude est caractérisé par des estrans noirs. L’exploitation du charbon dans la région de Cam Pha et de Ha Long expliquent un apport énorme de particules carbonées qui créent des estrans vaseux noirs tout à fait originaux. Cependant, les espaces intertidaux de ce secteur n’ont jusqu’à présent pas fait l’objet d’une étude détaillée. La présente thèse a pour objectif de répondre à quatre questions concernant ces espaces intertidaux :1. Comment la morphologie des estrans a-t-elle évolué depuis les 25 dernières années ?2. Quels sont les sédiments constituant ces estrans : granulométrie, teneur en carbonates, teneur en matière organique, etc. ?3. Quels sont les paramètres biophysiques de surface des estrans ?4. Quels sont les facteurs qui influencent les changements de morphologie des estrans et comment ces derniers peuvent-ils évoluer ?Afin de répondre à ces différentes questions, des images de télédétection tant optiques (Landsat, Spot, Aster, etc.) que radar (Sentinel-1A) ont été utilisées. Les analyses spatiales ont été réalisées à l’aide d’un système d’information géographique (SIG).Le présent travail est une thèse financée dans le cadre du programme liant l’Université de Sciences et Technologies de Hanoï et l’Université de Reims - Champagne-Ardenne, membre du consortium USTH. / Tidal flat is a special environment suffering tidal regime in which tidal flats are submerged during flood tide and exposing the air during ebb tide. Tidal flats in the north coast in Vietnam are constituted in diurnal tide condition with tide range varying from 0.3m to 3.5m. Along 350km coastline of the study area, the diversity of constituent conditions formed various tidal flats with different characteristic. Tidal flats in the southern part of the study area are fed by sediment from two large river systems, in the middle part forms the coal tidal flats, but the only sandy sediment along with tide domination constitute the large tidal flats in the north coast of the study area. This study apply remote sensing techniques and GIS tools to solve four scientific issues including: the evolution of tidal flats over periods from 1989 to 2014, the characteristics of sediments in tidal flats, the surface parameter of tidal flats, and the forcing factors which influence the future change of tidal flats. The results of the study shows that, tidal flats in the north coast in the study area are dramatically eroded but the tidal flats in the south coast are deposition by the concentration of fine sediments. In total 14 forcing factors, the coastal nature factor has highest forcing to the deposition of tidal flats. However, the factors of wind-wave effect and tidal flat width have negative influence to deposition. Consequently, the highest potential for future deposition of tidal flats are around the river mouths in the south coast but no potential for future deposition is in tidal flats in the north of the study area. This study is implemented in the framework of the cooperation between University of Science and Technology Ha Noi (USTH) and Université de Reims Champagne-Ardenne (URCA).

Approaches to conserving biodiversity have traditionally left humans out of the picture. However, to separate between humans and protected areas has become increasingly criticized for being ethically problematic and ineffective. As a result, the political landscape for how biodiversity should be conserved has changed during the last 30 years. Instead of exclusive conservation practices, there is a request for so-called people-centered practices that tackle development and conservation jointly. However, several studies show a gap between public policies with people-centered ambitions and what is happening on areas assigned for biodiversity conservation. This study aims to understand if people-centered ideas are converted into conservation practices at four nature reserves in Cape Town, South Africa. The study also hopes to explain if the public-civil partnership Cape Flats Nature (CFN) is a useful arrangement in order to convert people-centered ambitions into practices. Using an ideal type analysis, conducting informant interviews and gathering documents, the findings suggest that people-centered practices are found at all four nature reserves. However, there are significant differences and the two nature reserves partnering with CFN have the most people-centered practices. In these cases, human well being is, for example, viewed to be an integral part of the objectives at nature reserves and fences that tend to keep people out are focused on to a lesser extent than in the other nature reserves that are not partnering with CFN. Even though there are no blueprint solutions, instruments such as CFN can be a useful arrangement for narrowing the gap between people-centered ambitions and conservation practices. However, further studies on for example social network analysis focusing on the role of bridging organizations would perhaps strengthen such claims.

Les Pertuis Charentais sont un site d’écosystèmes interconnectés où les courants marins jouent un rôle déterminant. Un modèle de marée à haute résolution a été développé au cours de cette thèse pour comprendre et cartographier les traits principaux de la circulation hydrodynamique dans les Pertuis. Deux axes sont ainsi mis en avant dans cette étude. D’abord, un nouveau modèle de marées dans les Pertuis Charentais a été construit et validé à partir de différentes sources : données marégraphiques, données de courantomètres ADCP et images satellitaires. Une nouvelle approche de calibration de modèle de marée a été développée, basée sur la comparaison de la position de la ligne d’eau, frontière entre l’eau et la terre, avec celle prédite par le modèle. Puis dans un second temps, le transport et les agrégations en « bloom » de populations de méduses Rhizostoma, dont les proliférations et les échouages sont à l’origine de problèmes socio-économiques, ont été simulés numériquement. Des observations in situ ont permis de paramétrer le comportement de nage des méduses dans le modèle. Deux types de comportements des méduses, actif et passif ont été simulés. Les courants de marées en présence des forçages-type météorologiques ont été pris en compte. Les résultats indiquent que le comportement individuel de nage des méduses pourrait être une réponse adaptative aux facteurs abiotiques qui menacent la continuité de leur espèce mais que les courants marins restent la cause première de la formation des blooms. / The Pertuis Charentais are an interconnected ecosystems site where ocean currents play a key role. A high resolution tidal model was developed in this thesis in order to understand the main features of the hydrodynamic flows inside the Pertuis. Two topics were put forward in this study. First, a new tide model for the Pertuis Charentais was build up and validated by using different datasets: tide gauge records, measurements of currents by ADCP and satellite images. A new approach to model calibration was developed by comparing the observed position of the waterline, the boundary between land and water, with that predicted by the model. Secondly, the transport and bloom-like aggregation of the Rhizostoma jellyfish populations were simulated numerically. The jellyfish proliferation and stranding are a source of socio-economic problems. Two types of jellyfish behavior, active and passive were simulated. The tidal currents and typical meteorological forcing were taken into account. The results show that the individual behavior of swimming jellyfish is an adaptive response to abiotic factors for jellyfish survival.

Magister Artium - MA / Adolescent substance abuse is a widely researched area both internationally and nationally. It has been known to affect many problems which are prevalent in most low socioeconomic communities such as crime, school truancy and family fragmentation. It is of particular concern in low socioeconomic communities within the Cape Flats District which continues to be plagued with social ills such as gangsterism, adolescent criminal behaviour, and high rates of school dropout. The problem of adolescent substance abuse cannot be explored in isolation, but rather, in conjunction with all other spheres which it affects such as family relationships, dynamics and functioning. Parents fulfil an important role in managing their adolescent's addiction problem. These parents often feel helpless, hopeless, guilty, and angry, and are inclined to blame themselves for their child's delinquent behaviour. In some cases spouses blame one another for their being too permissive or too stern. However, there is a dearth in research of parents' lived experiences and the ways in which they attribute meaning to their situations. The aim of this study was to explore parents' lived experiences of their adolescent's substance abuse. More specifically the study explored parents' perceptions of the ways in which one family member's substance abuse affects the dynamics and the functioning of the family. At a theoretical level, this study aligned with Bowen's Family Systems theory, as it allowed the researcher to explore the ways in which family roles, dynamics and functioning are affected by a relative's substance addiction. The current study was conducted within the qualitative methodological framework, as the aim was to gain an in-depth understanding of parent's lived experiences of managing their adolescent's substance abuse. Furthermore, this study was positioned within the phenomenological epistemological framework as it aligns well with the aims of this study, which is to acquire an understanding of parents' lived experiences of their adolescent's substance abuse.

This diploma thesis deals with the supply of heat in a particular block of flats in Brno. It deals with supply for heating and for hot water heating. The introduction gives information about the considerated building and also generally, but especially with regard to the current situation with consumption and heat supply. Subsequently, the thesis describes the individual possibilities of obtaining heat. There are mentioned classical heat sources as gas boilers, but also less commonly used as co-generating units or solar collectors. Furthermore, the work is calculating from the technical and economic point of view for heating options chosen by the investor. Finally, the work compares the options from viewpoint of benefits, budgets and returns of possible investments.

This architectural study offers a solution of the Gemini High School‘s new bulding, /Brno Lesná, the bulding site number 202/9, Vaculíkova street/, and shows a new building of a house of culture with a commercial area instead of today’s school /the bulding site number 253/. The new way of car parking and strenghtened areas of this street are included. The building and pulling down of today’s houses and buildings are devided into 2 phases. In the first phase a new barrier – free school building with a possibility of accommodation and flats is designed /building site number 202/9. This bulding has got two entrances. One from the northern part is for a school and the second one in the west is for the tenants. The school area is spread among the first and the third floor (classrooms, canteen, offfices). The fourh floor is used for students‘ accommodation and for a terrace entrance. There are some flats (2+1, 3+ small kitchen, max. area 120 m) from the fifth to the tenth floors. In the underground the are some tenants‘ cellars and technological rooms for school. The renewed car parking for all the tenants, school visitors and others is provided in Vaculíkova street. After the firt phase of building the new school project will go into the second part. In that time the old school will be pulled down and a new house of culture is designed in this place. There will be restaurant, commercial area, cinema, library – café and gym – fitness. On the first floor there are a restaurant, a library – café a cinema. On the second floor there are a gym – fitness and a commercial area. Car parking for the visitors is provided in the underground - 52 cars + 4 handicapped people. The green roof of this house is designed to be comfortable to watch it from the neighbourhood and do not damage the look of this new building. To finish all this project means to create the public area between the two new buildings. A nice place for meeting people and a cultural events will be bo
