[1] Erosion by bedrock river channels is commonly modeled with the stream power equation. We present a two-part approach to solving this nonlinear equation analytically and explore the implications for evolving river profiles. First, a method for non-dimensionalizing the stream power equation transforms river profiles in steady state with respect to uniform uplift into a straight line in dimens...

Digital media offers great possibilities to present cultural heritage: visitors can interactively explore content and the content can be dynamically presented according to the situation in the exhibition. For instance, little content may be presented in larger letters if the visitor is standing far away from the exhibit, but if the visitor is coming closer, a larger body of content can be prese...

Fish assemblage was investigated during the study of longitudinal profile of the Ehania River Basin in south-eastern Côte d’Ivoire. This area is subjected to intense human activities with many plantations (palm tree, banana, pineapple, coffee, rubber and cocoa). Samples were collected, with gillnets of different mesh sizes, through 6 sampling surveys during dry and rainy seasons from February ...

Concentrations of copper (Cu), silver (Ag), and cadmium (Cd) in eastern oysters (Crassostreu tirgkicu) from the upper Patuxent River estuary analyzed since 1986 (Cd since 1991) were high relative to concentrations in other sites in the United States analyzed by the National Oceanic and Atmospheric Administration National Status and Trends program. Patuxent River oysters had above average concen...

Urban green spaces or open play a critical role in sustaining urban natural environments and the social systems that use these spaces. Park accessibility is identified as one of major factors influencing park utilization. This study aim to identify Kupang Nostalgia Park. Data were collected through questionnaires from 100 visitors. used descriptive statistics crosstabs analysis. There are relat...
