Abstract

Ein im normalen Betrieb geeignetes Material für Dieselrußpartikelfilter stellt Cordierit dar. Bei der Filterregeneration, die nötig ist um die im Betrieb akkumulierten Rußpartikel abzubrennen, kann es zu Reaktionen mit Aschebestandteilen kommen, wodurch der Filter geschädigt wird. Um dies zu verhindern, wird ein Schutzschichtmaterial identifiziert und ein Verfahren etabliert, womit die Porenkanäle des Filters beschichtet werden, um die durch

Abstract

Built on 'the bend in the Red River', Hà Nội is among Southeast Asia's most ancient capitals. Over the centuries, it took shape in part from a dense substratum of villages. With the economic liberalisation of the 1980s, it encountered several obstacles to its expansion: absence of a real land market, high population densities, the government's food self-suffciency policy that limits expropriations of land and the water management constraints of this very vulnerable delta. Since the beginning of the new millennium, the change in speed brought about by the state and by property developers in the construction and urban planning of the province-capital poses the problem of integration of in situ urbanised villages, the importance of preserving a green belt around Hà Nội and the necessity of protection from flooding. The harmonious fusion of city and countryside, which has always constituted the Red River Delta's defining feature, appears to be in jeopardy. Working from a rich body of maps and field studies, this collective work reveals how this grass-roots urbanisation encounters 'top-down' urbanisation, or metropolisation. By combining a variety of disciplinary approaches on several different scales, through a study of spatial issues and social dynamics, this atlas not only enables the reader to gauge the impact of major projects on the lives of villages integrated into the city's fabric but also to re-establish the peri-urban village stratum as a fully-fledged actor in the diversity of this emerging metropolis.

Abstract

Installée dans « le coude du fleuve Rouge », Hà Nội compte parmi les plus anciennes capitales d'Asie du Sud-Est. Au fil des siècles, la ville s'est constituée sur un dense substrat de villages. Avec l'ouverture économique des années 1980, Hà Nội rencontre de nombreux blocages pour s'étendre : l'absence d'un réel marché foncier, des densités très élevées, une politique d'autosuffisance alimentaire qui limite les expropriations et la contrainte hydraulique de ce delta très vulnérable. Depuis le début du nouveau millénaire, le changement de vitesse opéré par l'État et les promoteurs immobiliers dans la construction et la planication de la province-capitale pose le problème de l'intégration des villages qui s'urbanisent in situ, du maintien d'une ceinture verte et de la protection contre les inondations. La fusion ville-campagne, qui a toujours fait la spécificité du delta du fleuve Rouge, semble remise en cause. À partir d'un riche corpus de cartes et d'études de terrain, cet ouvrage collectif montre comment l'urbanisation au ras des terroirs est confrontée à l'urbanisation « par le haut », la métropolisation. Combinant les approches disciplinaires à plusieurs échelles spatiales et sociales dans une perspective dynamique, il permet de mesurer l'impact des grands projets de développement urbain sur la vie des villages intégrés dans la fabrique de la ville, et de replacer la strate villageoise périurbaine comme acteur à part entière de la diversité sociodémographique de cette métropole en formation.

Abstract

Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundred
