A high surface impedance can be achieved in a limited frequency band by using composite structures. Based on the principles of causality, passivity, linearity, and time translational invariance we demonstrate that this bandwidth is bounded by the thickness and magnetic polarizability per unit area of the structure at normal incidence.
Amperometric carbon paste peroxide sensors based on horseradish peroxidase (HRP) were developed. In the first approach, HRP was chemically modified with polyethylene glycol to improve the stability of the enzyme in the organic paste matrix and compared with native HRP electrode. In the second approach, HRP was "wired" with a redox polymer containing a covalently bound phenoxazine type mediator, to
Professionals who take part in the building process have long been concerned with the same environmental factors, e.g. spatial layout, capacity, and function, as well as user demography. Through the knowledge gained on the ways environmental factors affect users of buildings, the need to understand how to handle these factors has grown, due to their influence on the building process. It will be sh
In this dissertion in Media History I study the history and development of online journalism in three Swedish local and regional newspapers: Helsingborgs Dagblad, Sydöstran and Ystads Allehanda. The starting point is historical: I have tried to anchor the three newspapers' decision to start their online newspapers in their own history and surrounding society. By following the three newspapers' wor
