Investigation of an Iron-Oxidizing Microbial Mat Community Located near Aarhus, Denmark: Field Studies.
We investigated the microbial community that developed at an iron seep where anoxic groundwater containing up to 250 muM Fe flowed out of a rock wall and dense, mat-like aggregations of ferricExpand

Investigation of an Iron-Oxidizing Microbial Mat Community Located near Aarhus, Denmark: Laboratory Studies.
We constructed a small flow chamber in which suboxic medium containing 60 to 120 muM FeCl(2) flowed up through a sample well into an aerated reservoir, thereby creating an suboxic-oxic interfaceExpand

The work of Jagadis Chandra Bose: 100 years of millimeter-wave research
Just 100 years ago, J.C. Bose described to the Royal Institution, London, U.K., his research carried out in Calcutta, India, of millimeter wavelengths. He used waveguides, horn antennas, dielectricExpand

Convenient formulas for quantization efficiency
[1] Digital quantization of signals prior to processing results in the insertion of a component of noise resulting from the finite number of quantization levels. In radio astronomy, for example, thisExpand

Magnetic field dependence of 1/T1 of protons in tissue.
It is well established that the spin-lattice magnetic relaxation rate 1/T1 of solvent protons in homogeneous protein solutions increases dramatically as the magnetic field is reduced well below theExpand

Modeling microbial chemotaxis in a diffusion gradient chamber.
The diffusion gradient chamber (DGC) has proven to be a useful experimental tool for studying population-level microbial growth and chemotaxis. A mathematical model capable of reproducing theExpand

A diffusion gradient chamber for studying microbial behavior and separating microorganisms.
The natural habitats of most microbes are dynamic and include spatial gradients of growth substrates, electron acceptors, pH, salts, and inhibitory compounds. To mimic this diffusive aspect ofExpand
