The fact that a growing number of pathogens develop resistance against traditional treatment is a growing medical problem. Infections, which until now have been harmless, might turn into life threatening diseases. These problems have led to an intensified search for alternative treatments. Analogs of cell surface glycoconjugates are an alternative. Ideally they prevent the adhesion of the pathogen
Popular Abstract in Swedish Ett flertal produkter som framställs inom den kemiska och biotekniska industrin produceras i stora turbinomrörda tankar. Kvaliteten av produkten och utbytet av processen påverkas av blandningsförhållandena i dessa tankar. Blandningsförhållandena i processen påverkas av vätskans hastighet och dess intensitet. I olika regioner av reaktorn, impeller regionen och bulk regiTurbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. Local turbulent flow parameters, the turbulent kinetic energy and the local energy dissipation rate,
Popular Abstract in Swedish Denna avhandling handlar om hur företag visar, och kan visa, miljöhänsyn vid upphandling av godstransporttjänster. Transporter är en starkt bidragande, och växande, faktor till många miljöproblem såsom den förstärkta växthuseffekten och hälsofarliga partiklar i luften. Behovet av transporter ökar ständigt till följd av exempelvis lokalisering av produktion till låglöneThe logistical activity of transport is one of the largest contributors to several environmental problems. One efficient and effective way to decrease the environmental impact from transports is to implement changes in the logistically related strategies and activities applied, such as the selection of transport suppliers. Consideration of the environmental aspect when purchasing transport servic
Ever since its first conception in 1907 by Bergson, "complementarity" has come to represent extremely wholistic situations, for which fragmentability into parts turn out unsuccessful. In 1927, Bohr used the term complementarity within quantum mechanics, with profound consequences, for a principally unsuccessful fragmentability into independent observability and definability concepts. The paper ob
The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor. The work presented in this thesis provides new information on the interaction bet
Popular Abstract in Swedish Avhandlingen handlar om den aspekt av människans självbild, eller självet, som på engelska kallas possible selves, och som på svenska skulle kunna kallas "möjliga själv" (en etablerad svensk översättning saknas). Detta är framtidsföreställningar eller framtidsbilder där vi ser oss själva i framtida situationer eller tillstånd, och teorin om möjliga själv presenterades fPossible selves are conceptions or images of ourselves in future states or situations. The theory about possible selves used in the present thesis was developed in a social cognitive tradition of research on the self, where the self is seen as a knowledge structure (Markus & Nurius, 1986). Possible selves are parts of this knowledge structure and possible selves are of importance for motivatio
Abstract Due to developments in the last decades in the field of protein production, new technologies for bio-separation have evolved. Especially in the field of affinity chromatography, the search for new ligands is of great interest. Besides the antibodies used as affinity ligands, synthetic ligands were introduced. Textile dyes were a first group to be introduced but despite their selectivity a
MicroRNAs (miRNAs) are post-transcriptional gene regulators involved in a wide range of biological processes including tumorigenesis. Deregulation of miRNA pathways has been associated with cancer but the contribution of their genetic variability to this disorder is poorly known. We analyzed the genetic association of gastric cancer (GC) and its anatomical and histological subtypes, with 133 singl
Measurements of the net CO2 flux between terrestrial ecosystems and the atmosphere using the eddy covariance technique have the potential to underpin our interpretation of regional CO2 source-sink patterns, CO2 flux responses to forcings, and predictions of the future terrestrial C balance. Information contained in FLUXNET eddy covariance data has multiple uses for the development and application
This article investigates verb placement, especially verb second (V2), in post-puberty L2 learners of two closely related Germanic V2-languages, Swedish and German. Håkansson, Pienemann & Sayehli (2002) have adduced data from L1 Swedish-speaking learners of German in support of the claim that the syntactic property of V2 never transfers from the L1 to L2 interlanguage grammars. Regardless of L
This paper is about interdisciplinary common initiatives to enhance and encourage quality of engineering education nationwide, by means of a scientific approach to teaching. To reach innovative pedagogical approaches it is seen as important to stimulate collaboration and knowledge sharing across discipline borders. STEM, referring to the academic disciplines of science, technology, engineering, an
Popular Abstract in Swedish De senaste 150 åren har erbjudit en dramatisk utveckling av vår förmåga att sprida både njutningar och smärta, både i form av upptäckter av ämnen såsom TNT och dynamit och framställningen av heroin och Viagra. Denna utveckling har följts av teknologiska framsteg som tillåter studier av dessa kemikalier genom deras interaktion med till exempel radiosignaler eller laser. Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic tech
Popular Abstract in Swedish Många av alla kemiska processer som pågår i våra kroppar utförs av proteiner. När de inte fungerar blir vi sjuka. I vissa fall, till exempel vid Alzheimers sjukdom eller Creutzfeld Jacobs sjukdom, beror det på att ett visst protein har fel form. Att förstå hur proteiner antar sin slutliga form och vad det har för inverkan på proteinets funktion är således viktigt. ÅVery little is known about a considerable part of all proteins and it is time consuming and expensive to study each individual protein to determine its function, structure and cellular role. Proteins retain structural, functional and sequential characteristics from ancestral proteins and hence two proteins that share a common ancestor, i.e. are homologs, will to some extent have similar sequen
Skattetillägg och sanktion för skattebrott är två sanktioner som båda riktar sig mot att bestraffa lämnandet av oriktig uppgift. De senaste åren har reglerna sprakat en debatt kring om de var förenliga med dubbelbestraffningsförbudet i EKMR och EU:s rättighetsstadga sedan praxis från Europadomstolen förändrades genom Zolotukhin-målet från 2009. I Sverige behandlade HD frågan i NJA 2010 s. 168 I Both tax surcharge and the sanction for tax crime aim to punish those who leave incorrect tax information. During the last couple of years, these rules have started a debate regarding their compatibility with European Convention on Human Rights and the Charter of Fundamental Rights of the European Union, and specifically the prohibition against dual criminality. The reason behind this is that the
Studien syftar till att beräkna det gröna, blå och grå vattenfotavtrycket vid odling och produktion av höstvete och tre fallstudier av höstvete-produkter; drivmedelsetanol, kärnvetemjöl och makaroner. Beräkningarna har utförts för Sverige under perioden 2008-2010 och täcker ungefär 80 % av den svenska produktionen av höstvete under de berörda åren. Södra Sverige delades in i 18 klimatzoner för vilThis study attempts to calculate the green blue and gray water footprint of the crop production of winter wheat and three derived winter wheat products: liquid fuel ethanol, wheat flour and macaroni. The calculations were done for Sweden for the period 2008-2010, covering an average of 80% of the annual winter wheat production. The south of Sweden was divided into 18 climate zones for which suffic
Syftet med detta examensarbete har varit att undersöka den processuella gången som följer då poliser begår våldsbrott i tjänst. Förfarandet innebär processer i flera instanser vilket leder till en rad problem, inte minst ur ett rättssäkerhetsperspektiv. Målet har varit att undersöka förfarandet så som det ser ut idag, att identifiera eventuella problem och att söka lösningar på dessa. Polisens aThe aim of this master thesis has been to examine the court proceedings when policemen commit violent crimes at work. The procedure involves processes in multiple instances causing a range of problems. The goal has been to investigate the procedure as it is today, to identify potential problems and to seek solutions to these problems. The police has a complex role in society and their work assig
The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. In Sweden, the forest industry is an important part of the economy. The pulp mills pro-duce an excessive amou
Nitrous oxide (N2O) is one of the three primary anthropogenic greenhouse gases. The agricultural sector accounts for 75.7 % of all anthropogenic N2O emissions in Germany (Umweltbundesamt, 2012). Thus, accurately estimating N2O emissions as well as mitigation strategies for N2O are crucial. This study optimizes the process-based model DNDC to simulate N2O emissions by conventional winter wheat and
Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illustrations of the scientific quality of the data, followed by a discussion of the limitations due to the preliminary nature of this release.

In the globalised world there is a keen competition market prevailing, which request higher demands on the entrepreneurs within the building sector. Research shows that 30-35 % of the production costs on the building sites is waste, which means non-profit value for the costumer. This example shows both hidden and visible costs, which has been identified on building constructions sites. To reduce t
