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

Internationellt har det sedan 1980-talet publicerades en rad offentliga rapporter och utredningar om hur prioriteringar inom sjukvården bör göras. Denna rapport är en översikt över den internationella debatten och en jämförelse med den svenska prioriteringsutredningens förslag.

Neuroblastoma is a childhood malignancy originating from cells of the sympathetic nervous system, exhibiting a marked diversity in outcome, with spontaneous regression at one end of the spectrum and severe disease and death at the other end. Features associated with frequent recurrence, a poor prognosis, and high tumor stage are loss of heterozygosity in the distal region of chromosome 1p and ampl

Författaren Per Olov Enquists förslag att ”stryka” Gamla testamentet och delar av Nya testamentet kritiseras, särskilt utifrån en jämförelse med Deutsche Christens motsvarande förslag 1933. Jag ifrågasätter också Enquists uppfattning att det inte skulle finnas någon ”kollision” mellan de fyra evangelierna och ”upplysningstanken”.

The rapid progress in scanning probe microscopy (SPM) techniques in the last decade has induced an increasing need for manufacturing advanced SPM tips. One important case is conductive and transparent tips. For such tips, only a few techniques have been proposed. which are either expensive or have poor reproducibility. We here propose a simple and cheap sol-gel technique to prepare fibers with a s

The use of short interfering RNAs (siRNA) for selective suppression of protein production has rapidly become a commonly used technique for transient modulation of protein levels. In the present paper, we investigate whether introduction of platinated bases in the sense strand can be used to modulate the efficacy of siRNAs. Four different siRNAs were studied, all targeting the initial AU-rich 3' UT

A number of filamentous fungi are known to produce high levels of saline-soluble and low-molecular-mass lectins. The function of these proteins are not clear but it has been proposed that they are involved in storage of nutrients, development, recognition of other organisms, and defense reactions. A gene encoding such a lectin (AOL) was deleted in the nematode-trapping fungus Arthrobotrys oligospo

The European food service market was estimated, in 1999, to be worth US$293 billion with high profit margins and a growth rate of 2.75%. Future demand for value-added products and high levels of customization will stress the issue of keeping profit margins in the food service industry. Packaging is a critical issue, because it adheres to the product throughout the entire food service supply chain.

We consider the problem of covering arbitrary polygons with rectangles. The rectangles must lie entirely within the polygon. (This requires that the interior angles of the polygon are all greater than or equal to 90 degrees.) We want to cover the polygon with as few rectangles as possible. This problem has an application in fabricating masks for integrated circuits. In this paper we will describe

Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. CFD modeling (computational fluid dynamics) has been used in the calculation of the flow field. The f

The problems following the translation of “queer theory” and of the term ”queer” into a non-American context still have an impact on the debates in the field of queer studies. Through a presentation of the discussions held at the PhD-course What’s up in Queer Theory? Recent Developments in Queer Studies organized in May 2007, the article investigates some of the implications following the translat

The article comprises the second part (Nostocales) of our study of little known planktic and metaphytic cyanoprokaryotes (cyanophytes, cyanobacteria) from ponds, lakes and water reservoirs in East and Southern Africa. The morphology and variation of 17 species was studied, and comments about their ecology and taxonomy are included. Seven new species are defined: Anabaena austro-africana, A. carmic

Popular AbstractI Sverige har utbildningspolitiken under de senaste decennierna fått en viktig roll i att främja målsättningar också inom en rad andra politikområden, bland annat det regionalpolitiska. Högskolorna skall bidra till att utjämna sociala och ekonomiska skillnader mellan olika grupper i befolkningen, stimulera innovationsförmågan i näringslivet och generera nya företag. UndersökningarnImportant goals in Swedish higher education policy, from the late 1960s all through the 1990s, have been to increase the accessibility to higher education and to increase the supply of newly educated labour in all parts of the country. These goals are based on the assumption that geographical distance matters. Geographical distance to universities is thought to act as a barrier to university entra

This statement provides a concise list of diagnostic terms for ECG interpretation that can be shared by students, teachers, and readers of electrocardiography. This effort was motivated by the existence of multiple automated diagnostic code sets containing imprecise and overlapping terms. An intended outcome of this statement list is greater uniformity of ECG diagnosis and a resultant improvement
