Methane is the second most important greenhouse gas after carbon dioxide, and it can significantly impact global climate change. Considerable amounts of methane can be released to the atmosphere from freshwater lakes, ...

This thesis focuses on mass transfer behavior, i.e., tailing, in solute transport, and on hydraulic conductivity heterogeneity. Macrodispersive theory, generally used to incorporate heterogeneity into solute transport, ...

This thesis develops methods for the measurement of activity and travel well-being and models for linking well-being and behavior. The hypotheses underlying this research are that (1) activities are planned to maintain or ...

The presence of aquatic vegetation is a common feature in shallow water systems. It alters the dynamics of the system by producing additional drag and by generating differential heating between regions of vegetation and ...

Metagenomic research has paved the way for a comprehensive understanding of the microbial gene parts list in nature, but a full understanding of microbial gene expression, regulation, and ecology remains a challenge. In ...

Bacterial chemotaxis, a remarkable behavioral trait which allows bacteria to sense and respond to chemical gradients in the environment, has implications in a broad range of fields including but not limited to disease ...
