Detection Instrument

A tsunami is a significant coastal hazard that causes destructive damage to coastal cities in the world. Besides, tsunamis, generated on the west coast of Japan, damaged coastal cities on the east coast of Korea in 1983 and 1993. In recent years, there has been increasing interest in the potential tsunami zone near the west coast of Japan. Therefore, it is important to have tsunami observation instruments in proper locations for tsunami detection and warning aspect. This study proposes the optimal region for offshore tsunami observation instrument deployment under the limited condition that the tsunami source in out of the territorial sea by investigating areas with the highest tsunami detection probability along with maximum evacuation time and bottom slope. Using the Cornell Multi-grid Coupled Tsunami (COMCOT) numerical model and a probabilistic approach, this study suggests the optimal region for offshore tsunami detection instrument deployment to be the northeast area of Ulleung-do Island in the eastern sea of Korea.

This chapter focuses on the early contact between Chinese and Americans, the lumber trade, the Chinese immigration to the American West, the recruitment of workers to North America, chain migration, and the importance of early Chinese organizations. It examines why and how the Chinese first came to the American West, what kinds of organizations they established, how they were recruited for work, and what they contributed to the building of the new frontier. It also considers how trade between the West Coast and China, and especially the latter's eastern coastal cities, developed and shows that most Chinese immigrants harbored the “American dream” and thus came voluntarily to the American West. Finally, it discusses some of the factors that worked against the Chinese's acculturation and assimilation, including, language and value differences.

Soil C

Humping/hollowing and flipping are land development practices widely used on the West Coast to overcome waterlogging constraints to pasture production. However, there is very limited information about how the resulting "new" soils function and how their properties change over time following these extreme modifications. We hypothesised that soil quality will improve in response to organic matter inputs from plants and excreta, which will in turn increase nutrient availability. We tested this hypothesis by quantifying the soil organic matter and nutrient content of soils at different stages of development after modification. We observed improvements in soil quality with increasing time following soil modification under both land development practices. Total soil C and N values were very low following flipping, but over 8 years these values had increased nearly five-fold. Other indicators of organic matter quality such as hot water extractable C (HWC) and anaerobically mineralisable N (AMN) showed similar increases. With large capital applications of superphosphate fertiliser to flipped soils in the first year and regular applications of maintenance fertiliser, Olsen P levels also increased from values

In Gold Rush–era California, banking and the financial sector evolved in often distinctive ways because of the Gold Rush economy. More importantly, the abundance of gold on the West Coast provided an interesting test case for some of the critical economic arguments of the day, especially for those deriving from the descending—but still powerful—positions of the “hard money” Jacksonians.

As práticas de campo proporcionam aos discentes uma proximidade com o cotidiano. A metodologia proposta no estudo sugere uma divulgação simplificada do conhecimento cientifico da Planície Litorânea de Almofala, propondo rotas de acesso didáticas para práticas de campo que auxiliem os professores das escolas de Itarema. Para a complementação teórica foram considerados como base os inventários da Geodiversidade cientifica do litoral oeste do estado do Ceará, realizados no âmbito do projeto PRONEX. Isso foi feito por pesquisadores de várias Instituições de Ensino Superior do Ceará, e a literatura clássica local. Enquanto resultados discutidos, considerou-se que estes roteiros de práticas de campo podem ser estabelecidos e decididos em conjunto, entre professores e alunos. Tendo como base o mapa interpretativo dos roteiros, com intuito de realizar o reconhecimento e entendimento da dinâmica costeira.Palavras-chave: Educação; Geodiversidade; Planície Litorânea. ABSTRACTField practices provide students with a closeness to daily life. The methodology proposed in the study suggests a simplified dissemination of scientific knowledge of the Almofala Coastal Plain, proposing didactic access routes for field practices that help teachers of Itarema schools. For theoretical complementation, the inventories of the scientific geodiversity of the west coast of the state of Ceará, carried out under the PRONEX project were considered. It was done by researchers from various Higher Education Institutions in Ceará, and its local classical literature. As results discussed, it was considered that these field practice roadmaps can be jointly established and decided between teachers and students. Based on the interpretative map of the roadmaps, in order to recognize and understand the coastal dynamics.Keywords: Education; Geodiversity; Coastal plain. RESUMENLas prácticas de campo ofrecen a los estudiantes una cercanía a la vida diaria.
