Popular Abstract in Swedish I en komponent som blir utsatt för en upprepande på- och avlastning, så kallad cyklisk belastning, kan små sprickor initieras och börja växa i materialet. Detta fenomen kallas för utmattning och kan få katastrofala följder, såsom haveri. För att med god säkerhet kunna dimensionera mot utmattning är det viktigt att på en mikro skala förstå de fenomen som ligger bakom sprFatigue implies repeated loading and unloading of a structure, and components subjected to fatigue might experience nucleation of cracks, and subsequent crack propagation. This might lead to catastrophic consequences, such as complete failure of a structure. In order to accurately dimension against fatigue it is of uttermost importance to have a thorough understanding of the mechanisms behind the

There is ample evidence that word order is a problematic domain in L2 usage. In particular, production of the verb-second (V2) phenomenon, which requires the finite verb in main clauses to appear in second position, (e.g., Ganuza, 2008 for an overview). Surprisingly, we know very little about how these structures are processed and how production relates to comprehension. We therefore examined how

Rising fuel prices and increasing environmental awareness emphasizes the importance of the transportation aspect in logistics. This calls for new improved inventory control methods that consider the effects of shipment strategies in a more realistic manner. This thesis, consisting of an introduction and three scientific papers, studies how shipment decisions can be included in the inventory contro

Popular Abstract in Swedish I dagens nya cellulära kommunikationssystem betraktas användandet av multipla mottagarantenner i kompakta användarterminaler som en nödvändighet för att kunna utnyttja fördelarna med diversitet och MIMO (Multiple Input Multiple Output) teknik och därmed uppnå god celltäckning och hög dataöverföringshastighet. Den senaste utbyggnaden av det cellulära kommunikationssystemCo-band multiple-antenna implementation in compact user terminals is necessary for harvesting the full potential of diversity and multiple-input multiple-output (MIMO) technology in cellular communication systems. The recent worldwide deployment of Long Term Evolution (LTE), which requires the use of MIMO technology in the downlink, adds to the urgency of achieving both practical and optimal multi

My Ph.D. examines women’s writing in the interwar period through a questioning of the boundaries between the public and private sphere as traditional masculine forms of power based on a system of sovereignty and law enter the domestic realm. I also consider how power might be reimagined abroad. I juxtapose works of popular fiction from E.M. Hull, Agatha Christie and Marie Belloc Lowndes with the m

Bolivia, a country located in the center of South America, has in the west part an Andean region, where the Poopó Lake is located. The area has many mineral resources, and thus since thousands of years,mining activity has had a large importance; however, mainly since colonial times, the extraction of these resources has been indiscriminate and the region of the Poopó Lake, has suffered the consequ

In the framework of the ESO Large Programme ``First Stars'', veryhigh-quality spectra of some 70 very metal-poor dwarfs and giants wereobtained with the ESO VLT and UVES spectrograph. These stars are likelyto have descended from the first generation(s) of stars formed after theBig Bang, and their detailed composition provides constraints on issuessuch as the nature of the first supernovae, the eff

Chronic myeloid leukemia (CML) is genetically characterized by the presence of the reciprocal translocation t(9;22)(q34;q11), resulting in a BCR/ABL gene fusion on the derivative chromosome 22 called the Philadelphia (Ph) chromosome. In 2-10% of the cases, this chimeric gene is generated by variant rearrangements, involving 9q34, 22q11, and one or several other genomic regions. All chromosomes hav

Textilproduktionen har beaktats utifrån de textilredskap som påträffats vid utgrävningar av bosättningar i Skåne, Mälardalsområdet samt Birka, Sverige och Hedeby nuvarande Tyskland. Redskapen oThe initial aim of the present PhD thesis was to develop the method of classification for textile tools to facilitate the study of textile production in an archaeological context. The thesis consists of five separate projects and a concluding summary. The study covers the late Iron Age, mainly the Viking Period. Geographically, the study covers the regions of Scania, in S.W. Sweden, with seven set

A systematic review of radiation therapy trials in several turnout types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for head and neck cancer is based on data from 39 randomized trials and I

Popular Abstract in Swedish Parkinsons sjukdom beror på att de dopamin-producerande cellerna i hjärnan dör. Detta leder till minskad rörlighet, svårigheter i att påbörja och avsluta en rörelse, balanssvårigheter och darrningar (tremor) hos de drabbade patienterna. Varför dopamincellerna dör är oklart och i nulägat kan man inte bota Parkinsons sjukdom, men man kan lindra symptomen med mediciner. PaParkinson's disease (PD) is a neurodegenerative disorder where the midbrain dopaminergic neurons are lost. Presently there is no cure for PD, and the most common treatment is to replace the lost dopamine pharmacologically by administration of the dopamine precursor L-DOPA. This works very well during the initial treatment period, but unfortunately a majority of the patients develop abnormal involu

Popular Abstract in Swedish Kvantdatorer har den unika egenskapen att de kan utföra samma beräkning för många olika startvärden samtidigt. Informationen i en vanlig dator är lagrad i ett minne som består av bitar, som kan ha värdena 1 eller 0. När ett program körs beror slutresultatet av startvärdena hos dessa bitar. Minnet i en kvantdator lagrar istället kvantbitar, som även de kan ha värdena 1 eThe main aim of this work, was to lay the foundations for the experimental realisation of a quantum mechanical controlled NOT gate in rare-earth-metal-ion-doped crystals. Small amounts of rare-earth elements, added during the growth of some inorganic crystals, will become substituted into the crystal lattice as trivalent ions. The trivalent rare-earth-metal ions between cerium, with atomic number

The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. Limitation of carbon dioxide and other emissions through emission regulations, carbon taxes, an

The purpose of this study is to analyze some aspects of the relationship between R&D and economic growth. In Chapter 2 we analyze how costly imitation may be incorporated into an R&D-driven endogenous growth model. In the model, optimizing firms allocate resources to innovation or imitation. Thus, the extent of technology diffusion through imitation is endogenously determined. Costs of im

The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. As a result of these disturbances new investigations have co

Popular Abstract in Swedish Transportsektorn står för 63% av Sveriges använding av kol, olja och gas. Biobränslen som etanol, biodiesel och biogas står bara för 6.8% av energin som används för nationella transporter, biogas står för 12% av detta. Ökad produktion av biobränslen för transproter behöver inte betyda minskad produktion av jordbruks- och skogsråvaror för annat. Dels kan restprodukter anBiofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. The European Energy Agency has identified several lignocellulosic crops, including industrial hemp, as more sustainable potential

Popular Abstract in French Phytoplancton invasif : génétique des populations, phylogéographie, et facteurs facilitant l’invasion par Gonyostomum semen De nos jours, les espèces invasives représentent une importante menace à la biodiversité. Une espèce invasive colonise un nouvel environnement, ou elle était absente, et atteint de forte densité rapidement, diminuant l’abondance ou remplaçant les esnvasive species is a major threat to ecosystems and biodiversity. Invasions by macroorganisms have been intensively studied, but little is known concerning microbial invasions. In aquatic environments, phytoplankton, i.e. autotrophic microbes, have a key role as primary producers. In my thesis, I focused on the population genetic structure and phylogeography of the freshwater raphidophyte Gonyosto

Popular Abstract in Swedish Kontaktallergi är en vanlig orsak till eksem i arbetslivet. Ett av de viktigaste arbetsrelaterade allergenen är epoxiharts. Det allergiframkallande ämnet i det vanligaste epoxihartset visades på 1970-talet vara det ämne, diglycidyleter av bisfenol A (DGEBA), som hartset är uppbyggt av. Dessa epoxihartser är sedan decennier med i den standardserie med allergiframkallandeEpoxy resins based on bisphenol A are well-known contact allergens and often cause occupational contact allergy. The most important allergen is the monomer diglycidyl ether of bisphenol A (DGEBA). Epoxy resins of the bisphenol F-type contain 3 isomers of the diglycidyl ether of bisphenol F; p,p'-DGEBF, o,p'-DGEBF, and o,o'-DGEBF, whereas epoxy resin(s) based on bisphenol A (DGEBA-R) contain virtua
