Evaluation of crumb rubber modified mixtures using performance based analysesSaxton, Robert W. 05 May 1994 (has links)
This study investigated the laboratory performance of crumb rubber modified
mixtures compared to a standard bituminous mixture using performance based test
procedures. This study was part of an asphalt resurfacing program for the Seattle
Washington area. Laboratory analyses were used to estimate the long term pavement
performance of these mixtures in the field. Six mixtures were tested: The standard
Class 'A' surface mixture for the Seattle area, Plus Ride II�� base course gradation (dry
process) using AC 5 and AR 4000W binder types, Plus Ride II�� surface course
gradation (dry process) using AC 5 and AR 4000W binder types, and ARHM-GG
surface course gradation using crumb rubber modified (CRM) AR 2000 (wet process).
The performance based tests used on each mixture evaluated the different failure
modes a pavement may encounter in the field: fatigue cracking, permanent
deformation (rutting), thermal cracking, age hardening, and water sensitivity. Many of
the tests used were developed by the Strategic Highway Research Program (SHRP) to
test for a mixtures susceptibility in these failure modes.
Test results indicate the CRM mixtures performed better than the Class 'A'
surface mixture, with respect to fatigue cracking. All of the Plus Ride II�� mixtures
performed inadequately when tested for permanent deformation. On the other hand,
the ARHM-GG surface mixture performed well, even better than the Class 'A' surface
mixture with respect to permanent deformation. The ARHM-GG surface mixture
showed better low temperature characteristics when compared to the Class 'A' surface
and Plus Ride II�� mixtures. The CRM mixtures were less susceptible to aging than the
Class 'A' surface mixture. Finally, all of the mixtures demonstrated low moisture
sensitivity.
The final conclusions were made relative to the Class 'A' surface mixture. The
ARHM-GG surface mixture performed as well as, and in some cases better than, the
Class 'A' surface mixture. The ARHM-GG surface mixture may be used where the
Class 'A' surface mixture was specified. The Plus Ride II�� base and surface (AC 5
and AR 4000W) mixtures did perform better than the Class 'A' surface mixture in
some tests, however it performed worse in others. Therefore, it was recommended
that the Plus Ride II�� mixture designs be re-evaluated to provide adequate performance
in the failed tests. / Graduation date: 1995

Framing Obama : A Comparative Study of Keywords and Frames in Two Washington NewspapersRenström, Caroline January 2011 (has links)
This study aims to contribute to the understanding of ideology conveyed by lexical items and framing of texts. Since ideology is embedded in language the frames used in newspapers construct a narrow ideological perspective for the readers to interpret subjects and events through. On the basis of editorials from The Washington Post and The Washington Times that cover President Barack Obama, the study examines how the editorials differ in their framing of Obama and which discourses and keywords occur unusually frequently in each newspaper. Findings suggest that when it comes to framing, The Washington Post allows for a relatively balanced perspective on Obama as they both support and criticise him, while The Washington Times overwhelmingly condemns and attacks Obama. A keyword analysis points to unusually frequent discourses on race, conservatives and reforms in The Washington Post, and spending, unemployment and political institutions in The Washington Times. Because of their ideological differences the newspapers construct a reality where the subject, Obama, is presented in very different ways.

Arab World Institute, Washington, D.C. : the Arabic modernism outside of the traditional Arabic cityMercho, Hassan Malak January 1991 (has links)
The actual need for such a building as the Arab World Institute is wellestablished because Arabs are searching for a solid relationship with Westerners. Growth is possible only through education. The Arab World Institute offers the opportunity for education, information, and entertainment, and serves as a hub of activity where all people-Arabs and otherwise-can meet and share cultural distinctions.The Arab World Institute will have at once:A cultural center for the need of the understanding of Arabic civilization,A museum to show the struggle for development in the Arabic world and to illustrate the cultural impact in a symbol of the city's past development,A library to express the architecture's poetic dimension.The Arab World Institute's buildings do not represent a single and imaginary moment in time, but a place of evolution and change. The Arab World Institute's mission will be:To develop a deeper knowledge and better understanding of Arabic culture, language, and civilization,To improve communication and cultural exchange between nations,To further The United States' relationship with the Arab world in order to contribute to developments in the rest of the world. / Department of Architecture

La ville de Washington dans l'après-Seconde Guerre mondiale (1945-1955) : une capitale instrumentalisée, enjeu et outil de politique nationale / Washington, D.C. in the postwar years (1945-1955) : instrumentalized capital city, stake and tool of national politicsGilli, Ludivine 17 June 2013 (has links)
Pendant la Seconde Guerre mondiale, la capitale étatsunienne connaît une croissance sans précédent et acquiert une position incontestée de quartier général des Alliés. La Washington de 1945 n'a plus rien à voir avec le paysage urbain peuplé mais somnolent de 1939. Suite à la guerre, que va-t-il advenir du District de Columbia ? Nombre d'acteurs de différents types et niveaux veulent avoir leur mot à dire dans le futur de la capitale. La plupart d'entre eux espèrent utiliser la ville pour promouvoir des intérêts particuliers. Au cours des années d'après-guerre, le District est le théâtre de nombreuses joutes symboliques, qui voient s'affronter l'ensemble des acteurs politiques, économiques et sociaux du pays. Les enjeux sont locaux, nationaux ou internationaux, ils concernent l'administration locale, le droit de vote, la ségrégation, les conditions de logement, etc., ils rejaillissent sur Washington à la fois en tant que ville-symbole et que ville habitée. Ces affrontements et leurs résultats incarnent la capitale et dessinent son futur tout à la fois. Nous étudions ici pourquoi et comment ces évolutions se produisent. Le combat pour l'égalité entre Noirs et Blancs dans le District, par exemple, ouvre la voie à des progrès sur le plan national. La lutte contre les taudis se déroule dans le cadre des programmes de redéveloppement urbain souvent associés au déclin des centres-villes. La lutte pour l'autodétermination et les efforts fournis pour développer les rôles national et international de Washington sont d'autres exemples des dynamiques à l'œuvre dans la capitale entre 1945 et 1955. Après une première partie consacrée à la situation dans le District à la fin de la guerre, afin d'exposer les enjeux qui se posent en 1945, nous examinons les spécificités et implications de son rôle de capitale, tant sur le plan national que sur le plan international. La troisième partie porte sur les évolutions urbaines et sociales dans la ville d'après-guerre. / During the Second World War, the Federal Capital of the United States experiences an unprecedented growth and acquires an uncontested international status as the Allied Forces' Headquarters. The Washington of 1945 is a changed city, nothing like the populated but sleepy urban landscape of 1939. In the wake of the war, however, the fate of the city 1 is in question: what will become of the District of Columbia (DC) ? Many different players in the urban, political and social game want to have a say in the future of the capital. Most of them, on a local as well as a national level expect using the city to promote a personal agenda. In the Postwar years, many symbolic battles are fought within the District's boundaries, pitting against each other the country's multiple players. The stakes are local, national or international; concern local policy, voting rights, racial segregation, housing conditions, etc.; reflect on DC as a symbol and as a real lived-in city. These battles and their different outcomes at once embody the city and shape its future. We study why and how this happens. The fight for racial equality, for instance, makes tremendous legal and actual headway in the city between 1945 and 1955, paving the way for progress on a national scale. The fight against the city's slums and substandard housing, however, can't seem to find a solution, which will lead infamous urban renewal programs to often be associated with bleak inner-city future. The fight for home rule and the efforts made to enhance Washington's national and international role are other examples of the significant dynamics at works in the Postwar era.

Predation on an introduced marine snail by native crabsBaker, Patrick January 1988 (has links)
Typescript.
Includes vita and abstract.
Bibliography: Includes bibliographical references (leaves 55-58). / Ceratostoma ioornatum is an introduced marine snail in Puget Sound,
Washington. Two of five native species tested as possible predators ate
Ceratostoma. These two species, the crabs Cancer gracilis and
Lopbppaoopeys bellys, did not eat native snails similar to Ceratpstpma,
but ate native and introduced bivalves more than Ceratpstpma. The
reasons for the differences in predation seemed to be explained by shell
strength of the prey species. The presence of Ceratpstpma adds a new
type of prey to the menu of the two crab species
at the sites studied.
