Limitations and possibilities for microbial degradation of organic contaminants in aquifers

Popular Abstract in Swedish Svensk populärvetenskaplig sammanfattning: Miljögift är mat för bakterier i grundvatten Jag har undersökt bakteriers nedbrytning av organiska miljögifter i grundvatten och intresserat mig för hur den påverkas av gifternas vidhäftning till sand och bakteriernas aktivitet och mångfald. Sådan kunskap kan bidra till att förhindra gifters spridning till t.ex. drickvatten. Many factors can influence the rate of microbial degradation of organic contaminants in aquifers. Some of these factors, e.g. sorption, the presence of dissolved organic matter (DOM), biomass, redox conditions, cometabolism, microbial community composition, and activity of degrading microorganisms, are addressed in the thesis, with the ambition to gain insights for bioremediation in aquifers, and

Väckarklockor

VÄCKARKLOCKOR är en helt omarbetad och utökad upplaga av boken Väckarklockor för människor i livets väntrum. Innehållet i denna bok har vuxit fram i nära samarbete med människor som lever med långvarig smärta och olika utbränningsdiagnoser. Väckarklockorna har använts som utgångspunkt för existentiella livsnära samtal i Värkstaden, där man arbetar med ett pedagogiskt koncept för rehabilitering av

Chemical Reaction Modeling with ThermoFluid/MF and MultiFlash

The free Modelica library ThermoFluid was developed for simulation ofthermo-hydraulic applications, both for single-species applicationslike the water-steam cycle in a thermal power plant and formulti-species applications with gas mixtures. It has demonstratedits flexibility for modeling thermodynamic and process applicationsin a variety of industrial and academic projects. This articledescribes h

Slepian-based serial estimation of time-frequency variant channels for MIMO-OFDM systems

This paper proposes a low-complexity two dimensional channel estimator for MIMO-OFDM systems derived from a time-frequency variant channel estimator previously proposed. The estimator exploits both time and frequency correlations of the wireless channel via use of Slepian-basis expansions. The computational saving comes from replacing a two-dimensional Slepian-basis expansion with two serially con

Constructing credibility through representations in the discourse of wine: Evidentiality, temporality and epistemic control

This study investigates the relationship between evidentiality, temporality and epistemic control through detailed interpretive analysis of wine reviews written by Robert Parker, whose outstanding authority in this particular discourse field provides an exceptionally fruitful backdrop for the exploration of credibility in discourse. The material consists of 200 entire reviews, which are divided in

Phonetics and phonology of the Swedish dialects - a project presentation and a database demonstrator

A searchable database of speech samples from more than 100 Swedish dialects is being established for use in research and education. Each dialect is represented by at least 12 speakers. Recordings are made of spontaneous speech as well as words and phrases elicited with a number of specific research goals in mind. This paper summarizes one of these goals, a prosodic typology for the Swedish dialect

NO, Immunosuppression and Tumor Immmunotherapy

Popular Abstract in Swedish Tumörimmunologisk grundkurs: En tumörcell har en gång i tiden varit en vanlig laglydig cell i någon av kroppens vävnader men på grund av arv eller dålig uppväxtmiljö så har denna cell upphört att följa de tillväxt begränsande regler som normala celler rättar sig efter. Förutom att kontrollen av celldelningen upphört så kan tumörcellen uppvisa ett mer eller mindre asociThis study aims at clarifying the role of NO in the immunosuppression induced by in vivo tumor growth and by tumor immunotherapy, and determining whether the inhibition of NO production can be used as an adjuvant in tumor immunotherapy. We have shown previously that tumor cells, glioma (N32) and colon carcinoma (H1D2), when genetically engineered to express such immune stimulatory cytokines as IFN

Changing minds by tracking eyes: Dynamical systems, gaze and moral decisions

Decision making is a dynamic process. Alternatives compete over time, and this competition plays out in sensorimotor processes. This is true not just for perceptual decisions or simple categorisation tasks, but also for moral decisions, which are the outcome of a complex interplay of intuition, emotion and reasoning. In this experiment, we first establish a descriptive and causal link between gaze
