In this article I discuss different ways of conceptualising the relation between liberty and law. By ‘law’ I refer throughout to law in the sense of civil law: rules with accompanying sanctions, promulgated by a legislator for the regulation of action in political society. I do not intend to say anything about ‘natural law’, unless I explicitly state otherwise. For the purposes of my argument I wi

This paper discusses the effects of cooled EGR on a turbocharged multi-cylinder HCCI engine. A six-cylinder, 12-liter, Scania D12 truck engine is modified for HCCI operation. It is fitted with port fuel injection of ethanol and n-heptane and cylinder pressure sensors for closed-loop combustion control. The effects of EGR are studied in different operating regimes of the engine. During idle, low sp

This paper explores motivational and cognitive effects of more neutral or androgynous-looking versus more feminine-looking and masculine-looking virtual characters. A user study is presented, in which 158 students, aged 17-19, encountered four virtual characters that were visually manipulated to represent gender stereotypicality versus androgyny. On the one hand we explored students’ attitudes tow

Discussion concerning media criticism and media pedagogy in modern education

This article explores what an ethic for organic animal husbandry might look like, departing from the assumption that organic farming is substantially based in ecocentric ethics. We argue that farm animals are necessary functional partners in sustainable agroecosystems. This opens up additional ways to argue for their moral standing. We suggest an ethical contract to be used as a complementary to t

This paper explores the potentials of solid oxide fuel cells (SOFCs) as 3 kW auxiliary power units for trucks and military vehicles operating on diesel fuel. Various issues are discussed, e.g., the requirements and specifications for the unit as well as the advantages, challenges, and development issues for SOFCs in such applications. System design and analysis are carried out. The major component

Popular Abstract in Swedish De flesta växter lever i symbios med mykorrhizasvampar. I mykorrhizaroten, som utgör kontaktzonen mellan växten och den omgivande marken, sker ett utbyte av energi (kolhydrater) från växten till svampen, och näringsämnen (t.ex. kväve och fosfor) som tagits upp av mykorrhizasvampen överförs till växten. Från mykorrhizaroten utgår det externa mycelet, nätverket av svamphyMost plants live in symbiosis with mycorrhizal fungi. Mycorrhizal roots constitute the interface between the plant and the soil, and almost every fine root of forest trees in nitrogen-limited boreal and temperate forests is colonised by ectomycorrhizal (EM) fungi. The mycelia of EM and ericoid mycorrhizal (ErM) fungi are very important for plant N uptake and N cycling in forest soils. Earlier labo
