Genetic variation, polyploidy and hybridization in Scandinavian Anthericum ramosum and A. liliago (Anthericaceae)

In this thesis, I investigate the differences in breeding system, levels of genetic variation and hierarchical structure of genetic diversity between Anthericum ramosum and A. liliago. The two species differ in ploidy level and flowering time, but have similar habitat preferences, reproductive biology and geographic distributions in Scandinavia. I also assess the potential for hybridization and ge

Applicability of a cognitive model and treatment to worry in children and adolescents

Studies have found that the cognitive model of worry developed by Dugas, Gagnon, Ladouceur and Freeston (1998) involving Intolerance of Uncertainly (IU), Cognitive Avoidance (CA), Positive Beliefs about Worry (PB), and Negative Problem Orientation (NPO) accounts for approximately 40-50% of the variance in worry frequency in adults. A recent trial of the treatment based on this model (Dugas, Brillo

Adsorption at the Solid-Liquid Interface: An Atomic Force Microscopy Study

The aim of the work presented in this thesis was to investigate nature of adsorption of amphiphiles to the solid–liquid interface. The surface aggregate structures of the zwitterionic surfactant dodecyldimethylammoniopropanesulfonate, (DDAPS) and a series of nonionic polyoxyethlylene glycol alkyl ethers (C10E5, C12E5, C12E8, C10E6, C14E6 and C16E6) have been determined by Atomic Force Microscopy o

Internationalising the Content of Higher Education

Internationalisation of higher education is a current theme in research and politics of higher education. The theme in this paper is related to present developments and concerns of the growing border-crossing activities that take place between nations and their systems of Higher Education. Higher education is expected to be grounded in research, research to be an international activity, and the un

Aktivister

Demonstrationerna i Seattle 1999 mot Världshandels- organisationen satte fokus på ett rörelseengagemang som växt i styrka sedan nittiotalet. Den svenska debatten om denna aktivism tog fart med demonstrationerna vid EU-toppmötet i Göteborg 2001. Genom framväxten av de sociala forumen sedan det första World Social Forum 2001 har den globala rättviserörelsen gått från protest till konkreta förändring

Resonant Tunneling Permeable Base Transistor for RF applications

A technique is developed to embed tungsten inside semiconductors, with the possibility to combine the metallic elements and semiconductor heterostructure with nm-precision. This technique enables to fabricate a very high quality permeable base type of transistor. A resonant tunneling permeable base transistor, RT-PBT is fabricated by directly integrating a tungsten grating 30 nm above a pseudomorp
