Moisture plays a critical role in several degradation mechanisms affecting the structural components of nuclear power plants. It also significantly influences the long-term structural behaviour of reactor containments. This study presents a novel hygrothermal model that uses the relative humidity as the transport potential and accounts for the presence of a thermal gradient across the containment
Popular Abstract in Swedish Föreliggande avhandling behandlar upplevelsen av ångest i stressfulla miljöer. Studierna i avhandlingen fokuserar framförallt på att undersöka två olika frågor. Den första frågan som undersöks är om en ökad ångest som personlighetsdrag kan förutsäga en sämre förmåga att utföra olika exekutiva kontrollfunktioner framförallt relaterade till aktivitet i hjärnan pannlob. DeThe present thesis deals with perspectives of anxiety experienced in stressful environments. As such two major issues are addressed. The first issue is whether increased trait anxiety during work in a high-stress environment is related to impaired performance on executive control tasks. The second issue is whether the characteristic of a stressor and pre-stress individual differences in executive
Popular Abstract in Swedish Leukemi är en cancersjukdom i blod och benmärg som karakteriseras av en störd blodbildning. Vid normal blodbildning delar sig ett begränsat antal omogna blodceller så kallade blod stamceller (eller hematopoietiska stamceller) och mognar till funktionella blodceller. Genom att dela sig utan att mogna har stamcellerna även potential till at förnya sig själva. När nya stamAcute myeloid leukemia (AML) is a malignant disorder of the blood system. Hematopoietic stem cells (HSCs) supply and maintain this system by differentiating via intermediates into lineage-restricted progenitors that strongly proliferate to keep up with the high turn-over of mature blood cells. In AML, the mechanisms controlling differentiation and proliferation of myeloid cells are disturbed leadi
The aim of this thesis is to explore the evolution of new technology-based firms (NTBFs) based on solid empirical material for the Swedish economy. NTBFs are argued to be one important type of entrepreneurial firms that contribute to technology change, knowledge spillovers, and economic growth. However, our knowledge concerning how NTBFs exert their technological and economic influences is far fro
Yttrium-90 is a pure β-emitting radionuclide with a high energy (Emax = 2.28 MeV) and a short half-life (T½ = 64.1 h). It has shown to be a promising isotope to use in radio-immunotherapy. In the absence of direct photon emission scintillation camera imaging can be obtained by acquiring events from bremsstrahlung photons created at or near the decay site of the radionuclide. It is, however, not ev
Popular Abstract in English Knowledge can be many things; it can be metaphysical, enhancing the understanding of human beings and social relations. It can be hard facts, information, structure and ordering of nature. Knowledge can be inherent in the knowing subject – the emancipated subject, or it can exist as an entity independent of its founder. An apposite metaphor is knowledge as an end in itsThis thesis deals with the colonisation of the university by market forces. The object of inquiry is coproduction of academic knowledge between academic and non-academic actors in newly established universities and university colleges in Sweden. The development of knowledge as a main competitive advantage for commercial companies, and the shift in policies accompanying this development, provides a
This paper presents a stabilized scheme that solves the wave propagation problem in a general bianisotropic, stratified medium. The method utilizes the concept of propagators, i.e., the wave propagation operators that map the total tangential electric and magnetic fields from one plane in the slab to another. The scheme transforms the propagator approach into a scattering matrix form, where a spec
Macroeconomic crises are common as well as economically, socially and politically costly. Fiscal policy plays an important role in alleviating the costs of the crisis. However, recent experiences suggest that the public finances are often unprepared for a crisis. Deficits and debt levels prior to the crisis are commonly too high, limiting the government’s ability to support the economy through the
High levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching.I studied a Norway spruce forest in a region of high N deposition in southwest Sweden and added N, P or N+P to force thesystem to N or P limitation. I studied tree
Deuterated biomolecules - where hydrogen atoms (H) are exchanged to its isotope deuterium (D) - are essential for biological experiments in neutron scattering, but they are not readily available. In neutron scattering, D has a strong positive coherent scattering length (6.67 fm) in comparison with the negative scattering length of H (-3.74 fm). These different characteristics of neutrons to D and
Background Increased postoperative cardiac troponin (cTn) independently predicts short-term mortality. Previous studies suggest that preoperative cTn also predicts major adverse cardiovascular events (MACE) and mortality after noncardiac surgery. The value of preoperative and perioperative changes in cTn as a prognostic tool for adverse outcomes has been sparsely investigated. Methods and findings
Gebel el Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point. The site is generally known for its many Pharaonic cenotaphs, stelai and the speos of Horemheb, but it was once also the world’s largest quarry. As such it was renowned for its high quality sandstone, and the stone was extracted and transported to all over Upper
Xenopus is a favorable experimental model in developmental biology. With its fast and external development, high number of progeny and large size, early embryos are well suited for micromanipulation to study the function of genes with relevance to human diseases. In this chapter, we present a combined method for lineage tracing and whole-mount in situ hybridization. In addition, we present protoco
It is important to study the factors affecting estimates of wetness since wetness is crucial in climate change studies. The availability of digital elevation models (DEMs) generated with high resolution data is increasing, and their use is expanding. LIDAR earth elevation data have been used to create several DEMs with different resolutions, using various interpolation parameters, in order to comp
The fracture toughness of a polymer-metal laminate composite is obtained by mechanical testing of a specimen containing a pre-crack. The laminate is a material used for packaging. It consists of a thin aluminium foil and a polymer coating. A centre cracked panel test geometry is used. Each of the layers forming the laminate is also tested separately. The result is compared with the measured fractu
