Membrane Optical Activity: Some Facts and Fallacies

Membrane optical activity: some facts and fallacies.

The circular dichroism of hypothetical, water-filled, spherical shells, 75-3500 nm in radius, with walls 7.5 nm thick, composed of poly(L-lysine) in various conformational proportions, and suspended in water, were computed from the known optical properties of this polypeptide by classical general light-scattering theory (Mie theory). Comparison of the computed curves of circular dichroism spect...

The Sir Harry Gibbs Inquiry into Community Needs and High Voltage Transmission Line Development in New South Wales and the debate on siting of the Richmond/Brunswick power line in Victoria have received a great deal of media at...

Radiation: facts, fallacies and phobias.

There is frequent debate in the media and the scientific published reports about the use of radiation for diagnosis and treatment, the benefits and risks of the nuclear industry, uranium mining and the storage of radioactive wastes. Driving this debate is increasing concern about reliance on fossil fuels for power generation for which alternatives are required. Unfortunately, there is generally...

Aggregation and Inference: Facts and Fallacies

This paper examines inference and aggregation problems that can ariee in multilevel relational database systems and points out some fallaciee in our thinking about these problems that may hinder real progrees from being made toward their solution. Although others have done come initial research toward solving inference problems, aggregation has been treated only superficially in the literature....
