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

Real-time applications introduce new requirements on wireless networks and impose quality thresholds on parameters like delay, jitter, throughput, and packet loss in order to run smoothly. This paper addresses this issue by presenting a MAC scheme that offers real-time applications the opportunity to reserve transmission time based on their QoS requirements for contention-free medium access. Our s

The chapter on Swedish employers' associations contains a calculation on collective bargaining coverage in 1995. Despite the absence of state extension mechanisms collective agreements in 1995 covered as much as 90 per cent of all private sector employees (p. 211). Including the public sector the rate was 94 per cent. The same year the density of employers' organisations was 77 per cent, i.e. 77 p

This dissertation is about the antagonistic conceptions of men’s violence against women – rape, incest and physical assault – as has been expressed by different actors in Sweden from 1975 – 2000. Mainly, my interest lies in how and why these conceptions have been articulated. During the studied period the attention to men’s violence against women as a question of gender, has grown remarkably. For

Two new African species of Teloschistes are described: T. arabicus Frödén sp. nov. and T. inflatus Frödén sp. nov. T. arabicus is a montane species, occurring in the southern parts of the Arabian peninsula and the adjacent parts of eastern Africa. T. inflatus is only known from South Africa, and was previously included in T. perrugosus Müll.Arg. Useful characters for distinguishing the misundersto
