Time-Domain Theory of Forerunners

The time-domain theory of forerunners (precursors) in temporally dispersive, nonmagnetic, isotropic materials is developed with the propagator technique. Specifically, the impulse response at a (comparatively) large propagation depth is expanded in two different ways: (a) with respect to the wave front and (b) with respect to slowly varying field components. A few numerical examples illustrating t

CLEAR: A novel family of highly cross-linked polymeric supports for solid-phase peptide synthesis

Cross-Linked Ethoxylate Acrylate Resin (CLEAR) supports were prepared by radical copolymerization, either in the bulk or suspension mode, of the branched cross-linker trimethylolpropane ethoxylate (14/3 EO/OH) triacrylate (1) with one or more of allylamine (2), 2-aminoethyl methacrylate·HCl (3), poly(ethylene glycol-400) dimethacrylate (4), poly(ethylene glycol) ethyl ether methacrylate (5), and t

Critical Systemic Thinking – or The Standard Engineer in Paris

In wanting to pursue critically informed research, we highlight a steppingstone we use in our struggle answering the question ‘How do we recognize what to critically reflect upon?’. When we, as researchers, try to apply critical thinking we may find that our descriptions of our reasoning undermine the purpose for those descriptions. We perceive problems to flow from an entrapment of mind in the ‘f

Measurements of long-term external and internal radiation exposure of inhabitants of some villages of the Bryansk region of Russia after the Chernobyl accident

A Nordic-Soviet programme was initiated in 1990 to evaluate the external and internal radiation exposure of the inhabitants of several villages in the Bryansk region of Russia. This area was one of the number of areas particularly affected by the nuclear accident at the Chernobyl Nuclear Power Plant in 1986. Measurements were carried out yearly until 1998 and after that more irregularly; in 2000,
