In the Shadow of the Dalahorse : Making Heritage and Creating Diversities in Swedish America
Heritage has always been an important vehicle through which the past has been mobilized in the present in the nameof specifc cultural identities and communities. Or more specically, as Barbro Klein taught us, “heritage is phenomena in a group’s past that are given high symbolic value and therefore, must be protected for the future” (Klein 2000:25). In what ways have contemporary political processe

Plattformssamhället : Den digitala utvecklingens politik, innovation och reglering
Begreppet plattformar har under de senaste åren seglat upp som ett av de mest centrala begreppen i den digitala ekonomin. Digitala plattformar möjliggör mängder av nya, effektiva sätt att organisera samhället – med långtgående konsekvenser för en rad centrala samhällsfunktioner. Detta ställer en rad frågor om medbestämmande och reglering, om innovationens förutsättningar och hur en plattformsmedve
Effects of starch granules differing in size and morphology from different botanical sources and their mixtures on the characteristics of Pickering emulsions
The aim of this work was to investigate how mixtures of starch granules of different size and shape from different botanic sources affect starch-stabilized Pickering emulsions, and to understand which type of granules that dominate at the interface of the emulsion droplets. Pickering emulsions were prepared by combining quinoa starch with waxy maize or oat starch. The effects of the individual sta
Particle-stabilized emulsions
This chapter describes particle-stabilized emulsions, the so-called Pickering emulsions. The principles behind particle stabilization of emulsions are described. The key properties of particle-stabilized emulsions such as stability, rheology, and the influences of other ingredients on the system, as well as some additional functional properties imparted by the stabilized particles in food emulsion
Formulation of emulsions
In this chapter, we describe some of the main concerns when it comes to formulating emulsions. This includes the choice of ingredients, such as emulsifiers, oils, preservatives, and thickeners. This is done with a focus on how these ingredients can give the desired properties of the emulsions, such as texture, flavor, nutrition, and stability. Commonly encountered thickeners and emulsifiers are de
Non-invasive monitoring of protein adsorption and removal in a turbulent flow cell
A flow cell was designed for continuous non-invasive measurements of macromolecular adsorption and removal under well-defined flow conditions. The adsorption of the protein β-lactoglobulin to stainless steel surfaces and its subsequent detergent-induced removal were followed in the flow cell using in situ ellipsometry under both laminar and turbulent conditions. Factors varied include the cleaning
The adsorption from solutions of β-lactoglobulin mixed with lactoferrin or lysozyme onto silica and methylated silica surfaces
The adsorption from pure protein solutions and binary mixtures of proteins with opposite net charges was studied at pH 7 by in situ ellipsometry. The investigated proteins were β-lactoglobulin, lactoferrin, and lysozyme. On hydrophilic silica surfaces, β-lactoglobulin (negatively net charged) adsorbed in small amounts while lactoferrin and lysozyme (both positively net charged) adsorbed in higher
Ecological and functional consequences of coastal ocean acidification : Perspectives from the Baltic-Skagerrak System
Ocean temperatures are rising; species are shifting poleward, and pH is falling (ocean acidification, OA). We summarise current understanding of OA in the brackish Baltic-Skagerrak System, focussing on the direct, indirect and interactive effects of OA with other anthropogenic drivers on marine biogeochemistry, organisms and ecosystems. Substantial recent advances reveal a pattern of stronger resp
Bleeding complications after cardiac arrest and targeted temperature management, a post hoc study of the targeted temperature management trial
Target Temperature Management (TTM) is standard care following out of hospital cardiac arrest (OHCA). The aim of the study was to evaluate if treatment temperature (33°C or 36°C) or other predefined variables were associated with the occurrence of bleeding in the TTM study. This study is a predefined, post hoc analysis of the TTM trial, a multinational randomized controlled trial comparing treatme
On the Matrix Riccati Equation
Properties of the algebraic equation ATX+XA−XBQ2−1BTX+Q1=0 are studied for arbitrary nonnegative definite and positive definite matrices Q1 and Q2. The results are used to study the possible number of stationary solutions of the Riccati equation. The theory for linear systems with quadratic loss is then generalized, and numerical consequences are studied.
A Constraining Hyperplane Technique for State Variable Constrained Optimal Control Techniques
A new approach to the numerical solution of optimal control problems with state-variable inequality constraints is presented. It is shown that the concept of constraining hyperplanes may be used to approximate the original problem with a problem where the constraints are of a mixed state-control variable type. The efficiency and the accuracy of the combination of constraining hyperplanes and a sec
On the Maximum Likelihood Method of Identification
The maximum likelihood principle of estimation applied to the linear black-box identification problem gives models with theoretically attractive properties. Also, the method has been applied to industrial data (various processes in paper production) and proved able to work in practice.This paper presents further developments of the method in the case of a single output. The reliability and speed o
Stability of Uncertain Systems with Hysteresis Nonlinearities
Stability of systems with hysteresis nonlinearities, parametric uncertainty and finite dimensional unmodelled dynamics is considered. Conditions for exponential decay of the signals in the system to an equilibrium position are given. The equilibrium is generally not unique. The stability condition is given in terms of a frequency domain inequality, which involves the transfer function of the nomin
Notes on Strict System Equivalence
It is shown that strict system equivalence in Rosenbrock's sense is equivalent to the existence of a certain bijective mapping between the sets of solutions to the differential equations describing the system. This leads to a simple proof of the fact that the equivalence classes under strict system equivalence are well defined, although the dimension of the system matrix is not uniquely defined. I
Simulations of Two Suboptimal Dual Controllers
Two suboptimal dual controllers are applied to a first-order linear system. The first controller is developed by Sternby and the second by Tse. Bar-Shalom and Meier. The second controller is slightly modified to serve in a stationary situation. The only unknown parameter of the system is the gain, which varies sinusoidally. It is shown that the effect on the system of the two controllers is much t
An algebraic theory for design of controllers for linear multivariable systems : Part I: Structure matrices and feedforward design
In this two part paper a theory is presented in which several control problems can be solved. The theory is applicable to a general class of linear multivariable systems where the measured output does not have to be equal to the controlled output or the state. The system may be affected by nonmeasurable disturbances. Only controllers which stabilize the system and have proper transfer functions ar
