Permittivity profile reconstructions using transient electromagnetic reflection data

This paper is concerned with the permittivity reconstruction of inhomogeneous dielectric media. The method applies to profiles that vary with depth only, i.e. it provides a one-dimensional profile reconstruction. The data are collected and analyzed in the time domain. In the first part of the paper the theory of the method is reviewed. It is showed that a finite time trace of reflection data suffi

Structural and Functional Studies of the Wilms' Tumour 1 Protein (WT1) in Interaction with Nucleic acids

The WT1 protein, a product of the Wilms’ tumour 1 gene (WT1) is a zinc finger transcription factor implicated in a number of cellular processes particularly involved in the development of the urogenital system. Mutations in this gene have been implicated in abnormal development of the urogenital system resulting in syndromes such as the Denys-Drash, WAGR and Frasier and in the childhood kidney mal

Pituitary adenylate cyclase activating peptide: a neuropeptide in the sensory nervous system.

This thesis deals with the expression of pituitary adenylate cyclase activating peptide (PACAP) in sensory C-type cells and primary afferent fibres and its possible role in nociceptive transmission. PACAP-expression, -release, -synthesis and -function were investigated in a series of measurements using immunocytochemistry, radioimmunoassay, in situ hybridization histochemistry, Northern blot, elec

On the physical limit of radar absorbers

A previous investigation has shown that at normal angle of incidence, the integral of the reflectance over wavelength is bounded for a flat metal backed absorber. The bound is applicable to any absorber made of linear, time-invariant, causal and passive materials. We generalize the physical bound to arbitrary angle of incidence and polarization. Different design examples and numerical calculations

Timber/Glass adhesively bonded I-beams

Timber and glass are materials with aesthetically pleasing properties. If the materials can be combined appropriately, drawbacks can be overcome and the beneficial mechanical properties utilised and timber/glass elements can be a natural part of the load-carrying structure of buildings. Since glass is a brittle material, an important task for the timber is to provide redundancy – a glass failure s
