The status of instrumentation, control and automation (ICA) within the European wastewater community is reviewed and some major incentives and bottlenecks are defined. Future trends of ICA are also discussed. The information is based on a COST 624 workshop and a non-exhaustive survey with regard to ICA carried out in 13 European countries during March 2001. The level of instrumentation (type of se

Om historieämnets försvagade ställning i svensk skola under 1900-talet och samhällskunskapsämnets stärkta ställning under samma tid.

The authors consider weighted Bergman spaces of holomorphic $L\sp p\/$ integrable functions with respect to certain Borel measures on a bounded plane region. A closed subspace $\scr M $ of such a space is said to be invariant if $z {\scr M} \subset {\scr M}$. In the case of the standard Bergman space of the unit disk with $p = 2$, the authors proved in a recent joint paper with C. Sundberg [Acta M

Fractionation of kraft black liquor by ultrafiltration is receiving a great deal of interest at the moment, mainly because the extracted lignin can be used as a biofuel, but also because there are indications that the pulp quality is improved when permeate is used instead of black liquor as the diluent in the cooking process. Fractionation of kraft black liquor calls for membranes that can withsta

A new method of correction of instrumental shifts and gain changes observed in experimental spectra is presented. An application of the method to the data collected in a large scale in-beam gamma-ray spectroscopy experiment is discussed.

Popular Abstract in Swedish Avhandlingens syfte är att analysera relationen och interaktionen mellan genus och nation i en svensk kontext under 1900-talets första hälft. När kvinnor mobiliseras nationellt inom olika typer av nationalism är det oftast moderskapet som åberopas. Detta är en av utgångspunkterna i avhandlingen. Föreställningar om ett nationellt moderskap återfinns också i flera olika sThe aim of this thesis is to analyse the relationship and interaction between gender and nation in a Swedish context, during the first half of the twentieth century. When women become mobilised on a nationwide basis within different types of nationalism, it is often motherhood that is invoked. This is just one point of departure in my dissertation. Perceptions of a national motherhood are also fou

This work focus on the functions by which the transcription factor Early B-cell Factor (EBF) regulate gene expression in different cell types. To address this question, gene expression analyses aimed to investigate the regulatory role of EBF in neuroblastoma cells, B-lymphocytes, adipocytes and stromal cells were performed. The addresses question is of crucial importantse for the understanding of

Urban wastewater systems are currently exposed to a major rethink dictated by new demands on resource management. It is postulated that next to providing efficient sanitation (preventing spread of pathogenic microorganisms) these systems should support resource reuse. It remains uncertain of what will be the sanitation of the future; the understanding of technical performances of various alternati

Popular Abstract in Swedish Avhandlingen består av fem upsatser (A-E): I uppsats A undersöks tidsberoende egenskaper hos kölängdsprocessen hos ett kösystem med flera betjänter under mycket allmänna Markovska ankomstprocesser. I uppsats B undersöks en endimensionell slumpvandring som reflekteras i två barriärer. I uppsats C undersöks ruinsannolikheten i en Cramér-Lundberg-modell där utbetalningaThis thesis consists of five papers (A-E). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x

A process for the fermentative production of lactic acid from whole-wheat flour consisting of starch and bran containing nutrients is presented and an economical evaluation of the lactic acid production cost performed. Bottlenecks were identified and alternative processes were evaluated and compared. The costs of raw material, the sodium hydroxide in the fermentation step, and the conversion of la
