Popular Abstract in Swedish De flesta produkter som vi dagligen använder tillverkas genom att utnyttja fossila råvaror som olja, kol och naturgas. Ett stort problem är att dessa råvaror bara finns i begränsade mängder i naturen, vilket medför att de förr eller senare tar slut. Dessutom medför förbränning av fossila råvaror att det bildas miljöskadande gaser (t.ex. koldioxid) som ansamlas i atmosfäOne of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. However, such utilisation requires the extraction of the biopolymers from th

The objective of this paper is to review the fundamental macroscopic modeling of linear complex materials in a time domain formulation. Based upon a set of basic assumptions, the general form of the constitutive relations for a linear complex media in the time domain is formulated. Furthermore, constraints on the possible form of the susceptibility kernels for a passive medium are presented. For c

This thesis investigates the reading of fiction by young pupils, and classroom work using reading as its starting point. The aim is to gather knowledge about the possibilities and limitations of some of the literary-pedagogical tools that are used in literature-based work in the years pre-school to third grade. The teaching aims to provide the conditions necessary for the pupils to build envisionm

The growing awareness of an impending environmental crisis coupled with a series of national and regional environmental disasters led, in the 1960s and 1970s, to the birth of the global environmental movement and the widespread recognition of the need to protect the environment for both current and future generations. Against this backdrop the concept of 'environmental rights' surfaced as a means

Popular Abstract in Swedish Epilepsi är ett tillstånd med återkommande attacker av abnorma, repetitiva och synkrona urladdningar i det centrala nervsystemet. Kindling är en djurmodell för en svårbehandlad form av epilepsi (med komplexa partiella anfall) som ofta har sitt ursprung i det s. k. limbiska systemet. Kindling är en mycket vällämpad modell för studier av utvecklingen av den ökade retbarheEpilepsy is a syndrome characterized by recurring attacks of sudden, excessive and synchronous discharge in populations of cerebral neurons. Kindling is an animal model for complex partial epilepsy, and is particularly useful for studies on the development of the abnormal excitability underlying the generation and spread of epileptic seizures. Here we have used the kindling model to investigate me

Popular Abstract in Swedish Immunsystemet utgörs av de celler och molekyler i kroppen som har till uppgift att skydda oss mot angrepp av sjukdomsframkallande bakterier, virus och parasiter. Dessa patogener hindras först och främst av fysiska barriärer såsom hud, slemhinnor och mag/tarm kanalen. Patogener som har lyckats ta sig igenom dessa barriärer, möter härnäst immunsystemets första försvarslinThis thesis is based on work studying the immunoregulatory mechanisms that govern the balance between activation and inactivation of T lymphocytes. Most of the work has been carried out in an experimental system using a T cell receptor (TCR-Vb3) transgenic mouse strain to obtain a homogenous T-cell population and utilizing the properties of bacterial superantigens to induce T cell responses and un

The Encyclopedia of Global Environmental Governance and Politics surveys the broad range of environmental and sustainability challenges in the emerging Anthropocene and scrutinizes available concepts, methodological tools, theories and approaches, as well as overlaps with adjunct fields of study. This comprehensive reference work, written by some of the most eminent academics in the field, contain
