A method is described for identifying simultaneous signals from different transmit antennas in multi-antenna sounders. Multiple orthogonal signals are produced from one pseudorandom code by using it to modulate RF carriers at pre-calculated offset frequencies. Although their frequency spectra are interleaved, the spectral lines from different transmitters are separable by Fourier transform at the

A virtual reality (VR) experiment with 96 participants was carried out to provide recommendations on the design of flashing lights on emergency exit portals for road tunnel emergency evacuation. The experiment was carried out in a Cave Automatic Virtual Environment (CAVE) laboratory at Lund University. A set of variables has been investigated, namely 1) Colour of flashing lights, 2) Flashing rate,

En skola för alla – är ett uttryck som beskriver en politisk ambition att skapa en för alla elever likvärdig grundskola i Sverige. Som verklighetsbeskrivning har uttrycket emellertid sina begränsningar och det är just det som utgör bakgrund till föreliggande text. En skola för alla har vi kanske främst om man väljer att fokusera på olika strukturella förhållanden: skolan är obligatorisk för alla u

There is increasing evidence that short-chain fatty acids (SCFA) formed by colonic fermentation of indigestible carbohydrates have beneficial physiological effects. Butyric acid is the main energy substrate for the colonic mucosa and has been implicated as important in the prevention and treatment of diseases of the colonic mucosa, such as distal ulcerative colitis and cancer. Propionic acid, on t

Introduction During the embodiment design and detail design phase, the designer has at his disposal a set of tools and techniques that him or her through the synthesis activity: basic rules, guidelines and principles (see [1]), but in the literature there are general design processes that help the designer to organize their work (e.g. [1]), but not at a very operational level. From a previous stud

A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for C_μ was also introduced to account for the

In Sweden, municipalities organize a large share of public services but the conditions for providing these services differ considerably due to differences in size and wealth. In the wake of financial stress and New Public Management reforms the Swedish local governments seeks new ways to make both ends meet and still manage the services to be in line with the present (not the past) demands of the

Vertebrate sex ratios are notorious for their lack of fit to theoretical models, both with respect to the direction and the magnitude of the sex ratio adjustment. The reasons for this are likely to be linked to simpilfying assumptions regarding vertebrate life histories. More specifically, if the sex ratio adjustment itself influences offspring fitness, due to sex-specific interactions among offsp

Initial investigations were directed at studying the interaction between polyamines and various glycosaminoglycans (GAGs). The polyamine spermine displayed binding to dermatan sulphate (DS) and heparan sulphate (HS) with similar (Kd, 3.9 x 10-4 M) and higher (Kd, 0.37 x 10-6 M) affinity, respectively, than to DNA. Antiproliferative spermine-binding DS fragments (tetra- to decasaccharides), and aff
