Extremely bright, short X-ray pulses, tuned to selected wavelength regions, are used to probe chemical reactions on surfaces, the electronic structures of semiconductors and magnetic materials, and the structure and function of proteins and biological macromolecules.
Fires constitute one major ecological disturbance which influences the natural cycle of vegetation succession and the structure and function of ecosystems.
Knowledge of the cell and the structure and function of the microbial community is necessary in the design of effective conventional and new treatment systems.
Archaea demonstrate unique structural features in the chemical makeup of their outer membranes and cell walls as well as in the components and design of their metabolic pathways, and the structure and function of their enzymes.
To help improve understanding of how changes in climate and land cover affect water fluxes, water budgets, and the structure and function of regional grassland ecosystems, the Grassland Landscape Productivity Model (GLPM) was used to simulate spatiotemporal variation in primary water fluxes.
This paper describes the physical nature of the Tongass National Forest, its salient natural resources, the social and economic importance of the resources, the complexity of the land management planning process, the chronology of the plan development, and the structure and function of the Pacific Northwest Research Station and Tongass National Forest planning partnership.
