The paper presents numerical results for a two-scale damage model accounting for mixed-mode propagation of micro-cracks. A time-dependent propagation criterion is assumed for microcrack growth and a kinking direction criterion based on the maximum of the energy-release rate is used. The macroscopic damage evolution laws are obtained by homogenization based on asymptotic developments. A numerical p
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
In the Grödinge project pottery was recovered from the five Neolithic sites, totaling c. 280 kg. A selected sample of pottery from four of these sites, i.e. the Eklundshov, Smällan, Kyrktorp and Kvedesta sites, has been studied more closely and also analysed technologically.
This paper presents the evaluation of parameters describing bond action between fiber-reinforced polymer (FRP) and concrete in RC structures strengthened in flexure. The parameters were evaluated on the basis of fitting nonlinear finite-element results to experimental results from literature. Three-dimensional (3D) finite-element simulations were used to account for transversal effects without int
This thesis deals with control of production at large-scale process industrial sites in the presence of disturbances. The main focus is on disturbances in the supply of utilities such as steam, cooling water and electricity. A general method for reducing the revenue loss due to disturbances in utilities is introduced, which may provide both proactive and reactive disturbance management strategies.
This paper examines Sweden’s role as a pioneer in mitigating climate change. Critical discourse analysis of climate and energy policy unveils Sweden’s ambition to ‘lead-by-example’, by virtue of a win-win combination of economy and environment via stringent regulations and an early-mover strategy on eco-innovations. The extent of the unilateral approach is constrained by concerns for the competiti
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
The paper presents main conceptual distinctions underlying much of modern philosophical thinking about value. The introductory Section 1 is followed in Section 2 by an outline of the contrast between non-relational value (impersonal good, or good, period) and relational value (good for someone, or—more generally—good for some entity). In Section 3, the focus is on the distinction between final and
Hormones and neurobiological factors may be regulated differently in suicidal versus non-suicidal depressive patients. There is currently limited knowledge about the relation of substances in the Renin-Angiotensin-Aldosterone system to depression and suicidality. We therefore investigated whether plasma levels of renin and aldosterone differ between suicide attempters, non-suicidal depressive pati
Abstract in Undetermined[Context and motivation] There is considerable flexibility in requirements specifications (both functional and non-functional), as well as in the features of available OSS components. This allows a collaborative matching and negotiation process between stakeholders such as: customers, software contractors and OSS communities, regarding desired requirements versus available

Swedish Development Cooperation emphasizes the need for collaboration among actors on a national level. In that context, the purpose of the thesis is to investigate how Public Private Partnership (PPP) on Corporate Social Responsibility (CSR) may influence the changing role of the state. The thesis is informed by Critical Discourse Analysis. In order to investigate the social constructions of real
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
