Chemical hypersensitivity is an immunological response towards foreign substances, commonly referred to as sensitizers, which gives rise primarily to the clinical symptoms known as allergic contact dermatitis. For the purpose of mitigating risks associated with consumer products, chemicals are screened for sensitizing effects. Historically, such predictive screenings have been performed using anim
Atherosclerosis is a chronic inflammatory disease characterized by the entrapment of apolipoprotein B– containing lipoproteins in the arterial intima, leading to local inflammation. T helper (Th) cell 1–mediated immune responses have been associated with atherosclerosis, and the cytokine interleukin-25 (IL-25 or IL-17E) has been reported to potentially regulate Th1 cell– and Th17 cell–related immu

The gastrointestinal tract of the foetus is considered sterile but during vaginal birth the neonate comes into contact with bacteria from the maternal vaginal and intestinal microbiota. The main focus of this doctoral thesis was to elucidate the initial bacterial ecosystem in newborns and to relate microbial perturbations to physiological traits. The bacterial flora was mainly studied with molecu
Popular Abstract in Swedish Många sjöar i Sverige och i andra delar av den norra hemisfären blir allt brunare. Detta beror på att mer färgat organiskt material (humösa ämnen) sköljs ut från den omkring liggande marken och transporteras sen in i sjöarna. I min avhandling har jag undersökt om detta leder till att det blir mörkare i sjöarna, och hur detta i så fall påverkar växtplankton, dvs. små mikWater colour is currently increasing in thousands of lakes in the northern hemisphere due to an increased input of terrestrial dissolved organic carbon (DOC), and more specifically coloured disscolved humic matter (DHM). I studied how water colour affects the light climate in the epilimnion and, as a consequence, phytoplankton biomass, species composition and production in lakes in southern Sweden
AI-baserad skönhetsrådgivning har blivit en del av hur skönhetsvarumärken försöker skapa mer personliga tjänsteerbjudanden. Genom verktyg för hudanalys, virtual try-ons och produktrekommendationer så kan konsumenter få råd som framställs som personliga och anpassade efter individens behov. Samtidigt bygger denna rådgivning på tekniska system som ska tolka visuella drag, däribland hudton och undert

Frågeställning: Vilka är de mest kritiska faktorer som påverkar lojalitetsprogrammets utfall, ur både kund- och företagsperspektivet? Syfte: Syftet är att beskriva fenomenet lojalitetsprogram samt att identifiera och analysera kritiska faktorer som påverkar utfallet av ett sådant. Metod: Inledningsvis gjorde vi en litteraturstudie för att skapa en teoretisk referensram kring problematiken. Vi har
This chapter explains vital elements in the salutogenic model of health and how these fit into the inner core of health promotion expressed in the Ottawa Charter for Health Promotion. Salutogenesis, is here considered as a theory, a life orientation and as the sense of coherence. In line with the salutogenic theory, health is described as a process in an ease/dis-ease continuum, defined as the mov
Popular Abstract in Swedish Katalytisk omvandling av enkla kolväten till mer användbara substanser m.h.a. homogena/lösliga komplex av övergångsmetaller är ett mycket viktigt ämnesområde inom metallorganisk kemi. För att förstå hur processen går till har ett stort antal modellföreningar syntetiserats genom åren där man har studerat hur kol-väte eller kol-kol bindningar kan brytas. Man bör notera atThe work presented in this thesis deals with metallacyclic late transition metal complexes, obtained by intramolecular Csp3-H activation, and the application of such compounds in catalysis. The new hemilabile P,O phosphines N-methyl-N-propionyl-2-(diphenylphosphino)benzylamine (DPPAM), o-(diphenylphosphino)benzoic acid ethyl ester (DPPES), o-(diphenylphosphino)benzoic acid methyl ether (DPPET) and
Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. However, many species of plants have somehow man
Trellis quantization is a finite state machine based method for data compression. It is mainly applied to quantizing noise-like sources. In this thesis new trellis codes suitable for low rate quantization are derived. Rate-distortion theory predicts source coding performance, but unfortunately provides only limited insight in how to construct good codes. In general, good trellis source codes combi
Popular Abstract in Swedish Etanol som produceras från förnyelsebara råvaror kan ersätta fossila bränslen som t.ex. bensin och diesel. Denna avhandling behandlar den enzymatiska processen för etanolproduktion från barrträd. Baserat på datorprogrammen Aspen Plus och Icarus Process Evaluator har ett verktyg för tekniska och ekonomiska beräkningar tagits fram i vilket hela processen, från trä till etEthanol produced from renewable resources can be used to replace fossil fuels such as gasoline and diesel. This thesis deals with the development of the enzymatic process used for ethanol production from softwood. A techno-economic tool, based on Aspen Plus and Icarus Process Evaluator, was developed in which the whole process, from raw material to ethanol, was studied and critical process paramet
Popular Abstract in Swedish Kärleksdofter och varningsljud i bekämpning av nattfjärilar Jag har studerat hur populationer av skadegörande nattfjärilar kan bekämpas med miljövänliga metoder där djurens egna sinnessystem manipuleras. Liksom många andra insekter kommunicerar nattfjärilar med artspecifika doftsignaler (feromoner) vid parning. Honan avger doften i enstaka nanogram (miljarddels gram!) The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. segetum under natural and pheromone-based mating disruption conditions was monitored by harmonic radar. Individual males were equi
Popular Abstract in Swedish Syftet med denna avhandling är att förstå och förklara frivården, som organisation och som praktik samt att få en fördjupad förståelse av förhållandet mellan stöd och kontroll. Avhandlingen bygger på två empiriska material. En studie av arkivhandlingar och publicerade texter från 1820-2000. En intervjustudie där tjugo frivårdsklienter, tjugo handläggare och tio lekmannaThe purpose of this thesis is to gain a deeper understanding of the relationship between support and control. The purpose is reached by a study of the probation service as an organization and the practical side of its work The thesis is based on two empirical studies. One is a study of records and published texts from the period 1820-2000. The second is an interview study, in which twenty probatio
We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in th

Starting from syntactic and semantic parsingcomponents,wedevelopedapplicationsthatcanhandlelargecorpora,typicallycomplete Wikipedia versions consisting of millions of documents and process text to identify entities and the relations between them.

Popular Abstract in Swedish Varför ser staden ut som den gör? Vilka krafter ligger bakom bebyggelsens och transportsystemets utformning? Vad eller vilka aktörer har inflytande över hur staden utformas? Hur kan internationella olikheter i städers utformning förklaras? De krafter som formar staden är många och komplexa. Stadens struktur har under historiens gång påverkats av bland annat nya teknologWhy do cities appear the way they do? What are the underlying forces that contribute to its built environment and transport system? What/whom are the factors/actors that influence the ways in which the city is shaped? How can the international differences in the shape of cities be explained? The driving forces that shape the city are numerous and complex. City structure, has through the ages, been
