Popular Abstract in Swedish En burk målarfärg som har lämnats bortglömd, en senapsflaska som länge har stått upprätt i ett kylskåp eller ett nyinköpt filmjölkspaket som precis ska öppnas. Det finns många vardagliga situationer där vi stöter på separation av fasta partiklar från vätskan i så kallade suspensioner. Separationsprocessen kallas sedimentering och är den tillämpning som genomgående motivA consistent theme throughout this thesis is quasilinear partial differential equations (PDEs) appearing in one-dimensional models of sedimentation for solid-liquid separation of suspensions. We mainly focus on continuous sedimentation in so-called clarifier-thickeners (CTs), which are found in mineral processing and wastewater treatment. In addition to complications with shocks and non-unique sol

Since about 25 years ago work has been dedicated to the development of hydrodynamical model atmospheres for cool stars (of A to T spectral type). Despite their obviously sounder physical foundation in comparison with standard hydrostatic models, their general application has been rather limited. In order to understand why this is, and how to progress, we review the present status of hydrodynamical

A stochastic model based on a probability density function (PDF) was developed for the investigation of different conditions that determine knock in spark ignition (SI) engine, with focus on the turbulent mixing. The model used is based on a two-zone approach, where the burned and unburned gases are described as stochastic reactors. By using a stochastic ensemble to represent the PDF of the scalar

Two observations serve as starting points for this paper. First, conventional risk assessment techniques provide sophisticated ways to identify and estimate hazards, but eschew the fact that there is no risk unless something of value is considered to be at stake. Second, what managers consider as being of value follows from how they organize their managerial practice. Based on these observations,

Popular Abstract in Swedish Villkoren för utbildning och undervisning förändras i väsentliga avseenden i takt med samhällets tilltagande komplexitet. Det är många gånger svårt för både lärare och elever att veta hur man på bästa sätt ska orientera sitt pedagogiska handlande. Med utgångspunkt från tre pedagogiska kontexter - grundskolan, de särskilda ungdomshemmen och grundskollärarutbildningen - pPedagogical practice is, in several important considerations, contradictory in character. In this dissertation attenention is drawn towards the field of tension that prevails between pedagogical action, which can be descibed in terms of strategic processes and communicative pedagogical action. While the former places the preconditions for effective knowledge development of the individual at the ce

We have previously proposed a blind system identification method that exploits the underlying dynamics of non-Gaussian signals in [Li and Andersen, "Blind identification of Non-Gaussian Autoregressive Models for Efficient Analysis of Speech Signals," Proceedings of the International Conference on Acoustics, Speech and Signal Processing (ICASSP), May 2006, vol. 1, pp. I-1205-1-1208]. The signal mod

The globalization of English in Sweden is examined as it takes shape in educational policy and practice. Following in the tradition of a “new wave” of language policy and planning research that emphasizes connections between policy and how it is interpreted by local stakeholders, this investigation focuses on textual data from Swedish national curricular documents and observational data of preserv

Initial results from the XUV undulator beamline at the 4.5 GeV storage ring DORIS are reported. The beamline consists of three different undulators mounted on a revolver type device and a modified SX-700 plane grating monochromator with a spherical focusing mirror. It covers the spectral range from 50–2000 eV with excellent spectral resolution and high photon flux. In the energy range 400 eV to 1

Generated aerosol particle deposition has been applied in laboratory scale to induce deactivation of commercial Selective Catalytic Reduction (SCR) catalysts of V2O5-WO3/TiO2 monolithic type. The monolithic catalyst has been exposed to the generated submicrometer particle of inorganic salts, KCl, K2SO4, and ZnCl2 at 200°C in a tubular reactor. The generated particles have been deposited on the cat

Despite a growing reliance on evolutionary theories when explaining industrial dynamics, the mechanism of selection has received limited attention. Selection is often taken for granted and conceptualised as product market competition. We go beyond this view and distinguish between different types of selection—formal and social—and consider how these lead to different entities being selected. Forma

This article brings the concept of kinning from anthropology and the sociology of adoption and care work to the study of disaster response and migration. It looks at intimate relationships between the Chernobyl children from Belarus and host families in Italy within the humanitarian programme of child recuperation abroad and argues that these relationships can be understood as kinning. Kinning imp

Some policymakers believe that academic R&D generates insufficient economic benefits. However, they often exclude the long-term and multi-dimensional impacts that are mediated through the activities of companies, students or policymakers. This case study, which is mainly interview-based, traces and characterises such impacts applying the technological innovation systems approach to the case of

Environmental research infrastructures (RIs) support their respective research communities by integrating large-scale sensor/observation networks with data curation services, analytical tools and common operational policies. These RIs are developed as pillars of intra-and interdisciplinary research, however comprehension of the complex, pathologically interconnected aspects of the Earth's ecosyste
