Popular Abstract in Swedish Hjälpsystem i tunga fordon (bussar)As more and more focus is put on the environmental questions and the request for cleaner transportation the demand on the vehicles increases. Especially the environmental request of the public transportation that is visible to the public and operates in the centre of the city. The demand on the buses used for public transportation will increase. The whole bus must be optimised, usually only the pr

Popular Abstract in Swedish Genetisk påverkan i ledgångsreumatism Ett väl fungerande immunsystem är en förutsättning för kroppens kamp mot diverse sjukdomar orsakade av t ex virus och bakterier. En grundläggande egenskap hos immunsystemet är dess förmåga att skilja på vad som är kroppens egna celler och molekyler och vad som är främmande. Ibland fungerar inte denna diskriminering som den ska och In this thesis the role of major histocompatibility complex (Mhc) class II molecules in development of autoimmune disease such as rheumatoid arthritis (RA), was studied. By combining an experimental model for RA, collagen type II induced arthritis (CIA), with molecular biology methods the importance of polymorphism in Mhc class II genes for disease development was investigated. The Mhc region con

The purpose of this study is to investigate the use of corpus linguistics, with a specific focus on the concordances in teaching and learning English in Vietnam. The concordance samples provide teachers and students with the information about the different patterns of use and structure that can be found for each word. I have designed a new kind of linguistics exercises on the basic of the selected

This study is one of the first that investigated youth’s response to unwanted Internet experiences, not only for those youth who were bothered or distressed but for all youth who reported the experience. Three types of response were examined: telling someone about the incident and ending the unwanted situation by active or passive coping. Responses to the following unwanted Internet experiences we

Popular Abstract in Swedish Lipasadsorption till fasta ytor studerades med hjälp av in situ ellipsometri. Samtidigt mättes aktiviteten av det adsorberade lipaset in situ genom hydrolys av p-nitrofenylacetat. Adsorption mättes till metylerade kiseloxidytor med varierande grad av metylering samt till rent kiseloxid. Olika lipaser studerades; lipas från Humicola lanuginosa (HLL)­vildtypen (WT) och enThe adsorption of lipases to solid surfaces was studied by means of in situ ellipsometry. In addition, the activities of the adsorbed lipases were measured in situ, by the hydrolysis of p-nitro phenyl acetate. Adsorption was made to methylated silica surfaces with varying degree of wettability as well as to clean silica surfaces. Lipases from Humicola lanuginosa (HLL) ­ the wild-type (WT) and a m

Background. The aim of this study was to investigate the occurrence and appearance of the anastomosis between the two umbilical arteries in placentas from infants small for gestational age (SGA). Methods. The arterial systems of 64 placentas from singleton pregnancies resulting in SGA infants were visualized by angiography. The method allowed study of the anastomosis between the umbilical arterie

The differentiation between expression and content is fundamental in the concept of signs. Even if the notions of signs are often revised, due partly to the attraction of a semiotic approach from markedly disparate objects of study, a common apprehension of the distinctive character of meanings by sign is its dual nature. (Saussure 1968, Piaget 1951, 1966; Vygotsky 1999; Sigel 1978; DeLoache 2000)

Purpose The purpose of this article is to explore the environmental impact of Logistics Service Provider (LSP) activities in the light of increased customer attention and fragmentation of the industry. We try to answer the question, to what extent the LSPs can actually monitor the environmental impact of logistics activities in the supply chain? Design/methodology/approach The methodology of this

Popular Abstract in Swedish I inledningen till avhandlingen görs tre viktiga antaganden som sedan kommer att ligga till grund för all vidare argumentering; (i) för det första görs ett (i sammanhanget kontroversiellt) ontologiskt antagande. Det antas att troper (dvs. partikulära egenskaper) existerar; (ii) för det andra antas (återigen kontroversiellt) att troper är det enda som existerar (åtminstoThe treatise attempts to approach and deal with some of the most fundamental problems facing anyone who wishes to uphold some version of the so-called theory of tropes. Three assumptions serve as a basis for the investigation: (i) tropes (i.e. particular properties) exist, (ii) only tropes exist (that is, tropes are the only basic or fundamental kinds of entities), and (iii) a one-category trope-t

Nuclear magnetic resonance (NMR) spectroscopy was used in order to investigate the relationships between structure, dynamics and calcium binding in the intracellular regulatory protein, calmodulin. Calmodulin consists of two similar domains, each binding two calcium ions with positive cooperativity. The studies described in this thesis focus on the isolated C-terminal domain, TR2C, and two mutants

Popular Abstract in Swedish Ovan jord & under ytan Sandstäpp är en hotad växtmiljö eftersom arealen av sandstäpp minskat avsevärt sedan Linnés tid (1700-talet). Vi ställde oss frågan varför den har minskat. För att kunna besvara den måste vi förstå vad växtarterna behöver och förstå hur kemin i marken fungerar. Dessutom vill vi lära oss hur markens organismer påverkas av minskningen av sandstSandy, calcareous grasslands are species rich temperate semi-natural grasslands. The species composition in 136 plots was analysed in relation to soil chemistry parameters; extractable P and N, soil pH and lime content. We found that that acidification and decalcification decrease species diversity and the number of red-listed species in these sandy grasslands. The microbial community was investig

The world of coastal fisheries is full of tensions and conflicts. On the public arena, professional fishing is often associated with the overtaxing of resources, unsustainable harvest practices and blame-games among actors. But fisheries are also upheld by boundary crossings, situated knowledge and relational work. Through the coexistence of such different patterns of rationality places are made.

The circulating zymogen form of Factor VII activating protease (FSAP) can be activated by histones and nucleosomes in vivo. These cell-death-associated nuclear factors are also actively extruded into the extracellular space by neutrophils through a process called neutrophil extracellular trap (NET) formation (NETosis). NETs are thought to be involved in host defense, inflammation as well as thromb

Little is known about the development of vision in wild birds. It is unknown, for example, whether the ability to see can be predicted by the level of prenatal growth or whether the eyes are open at hatching in a particular species. In this study, we investigated the growth of eyes, the formation of retinal ganglion cell topography, and the appearance of simple, visually guided behaviours in chick

Block copolymer-surfactant "complex salts" (BCPCS), containing one neutral water-soluble block and one polyion/surfactant-ion block, were prepared from poly(acrylamide)-block-poly(acrylic acid) block copolymers by neutralizing the acrylate charges with cationic dodecyl- or hexadecyltrimethylammonium surfactant counterions. The BCPCS were studied in hydrated samples containing 20-99 wt % water (and

AIMS/HYPOTHESIS: Salt-inducible kinase 2 (SIK2) is downregulated in adipose tissue from obese or insulin-resistant individuals and inhibition of SIK isoforms results in reduced glucose uptake and insulin signalling in adipocytes. However, the regulation of SIK2 itself in response to insulin in adipocytes has not been studied in detail. The aim of our work was to investigate effects of insulin on v

The Nordic Centre of Excellence CRAICC (Cryosphere-Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011-2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research and innovation regarding climate change issues in the Nordic region. CRAICC gathered more than 100 scientists from all Nordic countries in a virtual

The freedom to express oneself as a citizen is paramount to contemporary democracy. However, this freedom is often questioned in relation to humour and the offence it might cause, especially in cases where humour is referred to as an excuse, as a defence to avoid criticism (Smith 2009). This article uses the concept of cultural citizenship (cf. Hermes 2005) to conceptualise citizen rights and resp
