Experiments on dry face turning offunctionallygraded heat treatable steel are conducted. The workpieces have a hardened zone of approx. 60 HRC and a non-hardened zone of approx. 30 HRC. PCBN tools are used with different feeds, cutting speeds and depths of cut. Measurements of residual stresses in the surface layer reveal compressive stresses in the hardened zone and tensile stresses in the non-ha

Popular Abstract in English Climate migration has become an iconic topic in international climate politics and policy. This work, combining political ecology, critical security studies and post-foundational theories, traces the changes of conflicting discourses across time and space, and assesses the different forms of security they interpellate. While initially attracting attention as a securityThis work seeks to de-naturalise climate-induced migration (CM). Combining political ecology and post-foundational theories, I read CM as a construct that reifies a series of phenomena into an issue to be researched and governed. By assessing the narratives, the knowledge, the logics and imaginaries on which conflicting discourses are built, I analyse the strategies of government they envision. I

Popular Abstract in Swedish Feromonmedierat parningssystem hos ett nattfly Min avhandlings huvudsakliga mål är att identifiera och bestämma faktorer som påverkar det feromon-medierade parningsystemet hos sädesbroddflyet Agrotis segetum. Dessa faktorer inkluderar både honkönets produktion av sexualferomon såväl som hankönets feromon-inducerade respons, men också andra överlevnads- och reproduktionIn a series of studies, carried out in the laboratory and in the field in southern Sweden, I have examined factors influencing the mating behaviour of the turnip moth Agrotis segetum. The reproductive potential of the sexes and the mating behaviour was studied. The reproductive potential of males is greater than that of females. Males are ready to mate every night, while females rarely mate more

Communication is a basic behaviour, found across animal species. Human language is often thought of as a unique system, which separates humans from other animals. This textbook serves as a guide to different types of communication, and suggests that each is unique in its own way: human verbal and nonverbal communication, communication in nonhuman primates, in dogs and in birds. Research questions

Quantum fluctuation of the energy is studied for an ultracold gas of interacting fermions trapped in a three-dimensional potential. Periodic-orbit theory is explored, and energy fluctuations are studied versus the particle number for generic regular and chaotic systems, as well as for a system defined by a harmonic confinement potential. Temperature effects on the energy fluctuations are investiga

Popular Abstract in Swedish I slutet av 1800-talet gjordes upptäckten att atomer bara kan ta upp eller sända ut ljus med vissa våglängder. Denna egenskap beror på att elektronerna endast kan befinna sig i ett av flera diskreta energitillstånd. Man säger att elektronerna är kvantiserade. Kvantiseringen är en effekt av att elektronerna i en atom tvingas hålla sig inom en mycket liten volym. Ju mindrIn this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy. The band alignment of GaAs pseudomorphically grow

Popular Abstract in Swedish Sammanfattning Bengt Lidforss (1868–1913) växte upp i ett konservativt professorshem i Lund. Han var mycket intelligent, och till att börja med var han också en lika skötsam som framgångsrik student. Han tog en omfattande och mycket uppmärksammad filosofie kandidatexamen redan vid 19 års ålder. Karriären borde alltså ha gått spikrakt fram till professuren i botanik, meBengt Lidforss (1868-1913) was professor of botany between 1910 and 1913. But after the turn of the century he also emerged as a charismatic leader within the Swedish working-class movement. He became one of its foremost publicists. In the social democratic newspaper Arbetet in Malmö he wrote about natural sciences but also about political, philosophical and literary issues. As a literary critic
