Town-based settlements were first developed in the northern Shenandoah Valley in the Virginia backcountry. Three phases of settlement evolution occurred. A well-developed central-place system was finally evident by the 1790s. Current settlement

In this paper, the AA. extend the coverage of paleoecologic sites in the Cascade Range by reporting on pollen records from Indian Prairie, in central Oregon. These data disclose the vegetational and climatic history of middle and high elevations

The purpose of this paper is to stress the importance of saprolite characterization for consideration on climatic conditions during saprolite formation and age of saprolites. Two weathering profiles located north of the Quaternary glacial limit have

Nonpoint source pollution is the leading cause of water quality degradation in the United States, and construction sites are a major source of nonpoint source pollution in developing areas. Using field sampling of runoff from treated and untreated
sites in North Royalton, Ohio, as well as computer modeling based on site condition maps, the AA. found that rapid application of surface cover dramatically reduced both the amount of sedimment generated by surface erosion and the concentration and total

L'instabilité politique en Birmanie (Myanmar depuis 1989) contribue à ce que la population ait un moindre attachement à l'Etat et au pouvoir central qu'au clan, à la tribu ou au dignitaire local. L'absence des facteurs nécessaires pouvant aider à la
création d'un état indépendant, voire autonome, fait décroître les possibilités de succès des minorités ethniques. De plus, la politique unitariste du gouvernement central n'incite pas à l'intégration car elle se focalise sur l'assimilation à une identité
