Popular Abstract in Swedish Avhandlingen behandlar förvärvsarbetande småbarnsföräldrars arbetsrättsliga ställning. Utgångspunkten i avhandlingen är att arbetsrättens regler om föräldraskap, trots sitt tämligen starkt formulerade rättighetsskydd, i praktiken har en förhållandevis svag normativ position i arbetslivet och i arbetsrätten. Föräldraskapsreglernas svaga position kan förklaras som ett resThis dissertation deals with the position of working parents in labour legislation and the protection. The starting point for the thesis is that the rules in labour law concerning employees? parenthood, despite the fairly strongly formulated protection of their rights, in practice have a relatively weak normative position in working life and in labour law. The weakness of the rules on parenthood c

The gain profile of a quantum cascade laser is strongly influenced by the lifetime of the carriers in the upper and lower laser state. The quantitative description of gain within the concept of nonequilibrium Green's functions allows for a detailed understanding of various features affecting the gain spectrum: Compensation effects between scattering processes in the upper and lower laser level, re

Despite a growing interest in critical social and political studies of climate change, the field remains fragmented and diffuse. This is the first volume to collect this body of scholarship, providing a key reference point in the growing debate about climate change across the social sciences. The book provides a new set of insights into the ways in which climate change is creating new forms of soc

Scanning tunneling microscopy induced luminescence (STML) has been used to investigate individual self-assembled InP quantum dots overgrown with GaInP. We will present results correlating the surface morphology with the optical properties of single dots. In particular, the strain induced energy-shift of the dot emission with increasing cap layer thickness and its relation to the overgrowth will be

This paper deals with the manual control of unstable systems, subject to control signal saturation. In particular we consider the Furuta pendulum, where the problem is to control the orientation of the arm manually while stabilizing the inverted pendulum. This paper presents an analysis which leads to an insight into the problem as well as the control strategy. This control strategy has been imple

Popular Abstract in Swedish Vattentransporten i växter är viktig för en mängd olika processer. De flesta fritidsodlare vet att vattentillgången påverkar växternas utveckling i stor utsträckning. För att solros ska kunna gro, växa, vända sig mot solen och bilda nya frön, behöver vatten flöda på ett kontrollerat sätt genom olika celltyper i växten. Växter transporterar vatten på olika sätt. Över lånPlant water channels are members of the very old Major Intrinsic Protein (MIP) family, with representatives in bacteria, fungi, animals, and plants. The genome of the model plant Arabidopsis thaliana contains 35 MIP genes. Based on protein sequence comparisons, the MIP family has been divided in four subfamilies: the PIP (Plasma membrane Intrinsic Protein), the TIP (Tonoplast Intrinsic Protein), t

We consider the problem of seeking the maximum of a scalar signal using a swarm of autonomous vehicles equipped with sensors that can take point measurements of the signal. Vehicles are not able to measure their current position or to communicate with each other. Our approach induces the vehicles to perform a biased random walk inspired by bacterial chemotaxis and controlled by a stochastic hybrid

Bigeye tuna (Thunnus obesus) have distinctive depth distributions and vertical movement patterns. They remain in the uniformed temperature surface layer at night and can descend to greater than 500 m depth at dawn. They thus mirror the vertical migrations of the small nektonic organisms of the deep sound scattering layer and extensively exploit these as a food resource. At their maximum depths, bi

Sales of Fairtrade labelled foods in grocery stores is a growing business in Europe and the United States. The aim of the labelling scheme is to improve working and living conditions for export-oriented small-scale farmers and hired labour in developing countries The purpose of this report is to analyse the effects of the Fairtrade labelling scheme (Rättvisemärkt in Sweden) using economics theory
