Vi har i detta examensarbete utfört samtidig mätning av värmeutveckling (hydratationshastigheten) och relativ fuktighet (självuttorkningen) hos hydratiserande cement. Denna studie har gjorts på fyra grundrecept med olika cement där vatteninnehållet har varierats för att få olika självuttorkning. Mätningarna av relativ fuktighet är utförda med RF-sensorer som ger utslag i millivolt som därefter omv
While the international community would like to think it does not happen crimes are committed by peacekeepers. There is a growing prevalence of the crimes of trafficking, rape, sexual slavery and enforced prostitution being perpetrated by peacekeepers. These are all gender-specific crimes against women. They are also the crimes that most often remain unpunished, especially when committed by peacek
The thesis aims to investigate whether Sweden is able to prosecute Swedish soldiers stationed abroad for genocide, crimes against humanity and war crimes. Sweden is currently reforming its armed forces and will continue sending more soldiers to armed conflicts abroad. Sweden is also a state party to the ICC and therefore has an obligation to be the primary actor in prosecution of such crimes with
BACKGROUND: Participants' study satisfaction is important for both compliance with study protocols and retention, but research on parent study satisfaction is rare. This study sought to identify factors associated with parent study satisfaction in The Environmental Determinants of Diabetes in the Young (TEDDY) study, a longitudinal, multinational (US, Finland, Germany, Sweden) study of children at
Numerous publications have described the importance of Bone Morphogenetic Protein (BMP) signaling in the specification of hematopoietic tissue in developing embryos. Here we investigate the full role of canonical BMP signaling in both adult and fetal liver hematopoiesis using conditional knockout strategies, since conventional disruption of components of the BMP signaling pathway result in early d
Multi-component reflection methods have gained acceptance for near surface mapping during recent years. Two case studies from Denmark employing shear wave reflection at different survey scales are presented. The first case study is a small site scale investigation to image the near surface lithology of a contaminated site. Here the S-wave reflection mapping was employed to update the Conceptual Si
The activation of dendritic cells (DCs) by microbes is mediated by pattern recognition receptors including the Toll-like receptors (TLR). Bacterial lipopolysaccharide acts via TLR4 whereas peptidoglycan and lipoprotein responses are mediated by TLR2. It is generally accepted that TLR binding to microbes occurs at the cell surface but this has not been directly demonstrated for human DCs. We show h
Fibronectin performs essential roles in embryonic development and is prominently expressed during tissue repair. Two forms of fibronectin have been Identified: plasma fibronectin (pFn), which Is expressed by hepatocytes and secreted In soluble form into plasma; and cellular fibronectin (cFn), an insoluble form expressed locally by fibroblasts and other cell types and deposited and assembled into t
Photodynamic therapy (PDT) with topical methyl aminolevulinate ( MAL) administered in two treatment sessions separated by 1 week is an effective treatment for actinic keratoses. This open prospective study compared the efficacy and safety of MAL-PDT given as a single treatment with two treatments of MAL-PDT 1 week apart. Two hundred and eleven patients with 413 thin to moderately thick actinic ker
Objective. To study the effect of valgus malalignment on knee osteoarthritis (OA) incidence and progression. Methods. We measured the mechanical axis from long limb radiographs from the Multicenter Osteoarthritis Study (MOST) and the Osteoarthritis Initiative (OAI) to define limbs with valgus malalignment (mechanical axis of >= 1.1 degrees valgus) and examined the effect of valgus alignment versus
Purpose Although there is evidence for interaction between epidermal growth factor receptor ( EGFR) and estrogen receptor ( ER), it is still not clear how this affects response to endocrine therapies like tamoxifen. Here we assess the relationship between EGFR expression and tamoxifen response, with a new quantitative technology. Patients and Methods A tissue microarray was constructed from breast
Using a recombinant mini-laminin-332, we showed that truncation of the three C-terminal amino acids of the gamma2 chain, but not of the C-terminal amino acid of the beta3 chain, completely abolished alpha3beta1 integrin binding and its cellular functions, such as attachment and spreading. However, a synthetic peptide mimicking the gamma2 chain C-terminus did not interfere with alpha3beta1 integrin
The molecular mechanism of substrate analogue interaction with Escherichia coli dUTPase was investigated, using the non-hydrolyzable 2'-deoxyuridine 5'-(α,β-imido)triphosphate (α,β-imido-dUTP). Binding of this analogue induces a difference in the far UV circular dichroism (CD) spectrum arguing for a significant change in protein conformation. The spectral shift is strictly Mg2+-dependent, does not
This master thesis explores the possibilities of social robot adoption in the hotel industry. Social robots represent a new product group, a radical innovation, that has yet not seen commercialization in the hotel industry in Sweden. Furthermore, previous research has requested studies that determine success factors for social robot adoption in specific markets. This thesis therefore investigates
I denna studie undersöks hur sju olika femvertising-reklamer kodar en feministisk kvinnlighet. Femvertising är ett begrepp som beskriver “female empowering advertising” och är reklam vars mål är att stärka kvinnor. Studien använder sig av en semiotisk bildanalys och Roland Barthes mytbegrepp för att analysera materialet. Studien granskar även reklamen utifrån teorin om commodity feminism och commo
This project commences with a personal reflection. I, the author, find myself on the verge of completing my academic journey and embarking on the pursuit of an independent life. This involves securing employment and establishing a place to call home, with the ultimate goal of starting a family. However, upon exploring housing options in my home country, Iceland, it has become evident that this end
Background: Diagnosis of Mycoplasma pneumoniae (MP) infection is traditionally based on serology, which may require more than two weeks for diagnostic antibodies to develop. PCR-based methods offer earlier diagnosis. During a community outbreak of MP infection, we compared seminested and real-time PCR of oropharyngeal swabs with serology for diagnosis of MP infection at different time points after
Improved management of agricultural soils to sequester carbon from the atmosphere is considered an important climate mitigation measure. Intensive agriculture often leads to degradation of soil organic carbon (SOC), contributing to climate change and loss of soil ecosystem services. Interventions in agricultural management can halt or reverse the loss of SOC. Annual SOC change rates for interventi
After the well-known spike in migrants crossing the Mediterranean in 2015- 2016, the EU has intensified its cooperation with third states on the field of migration. Although there are numerous examples where such policies have been criticised as incompatible with the principle of non-refoulement and for not respecting migrants’ human rights, there are no CJEU rulings concerning their complianc
