The implementation of highly magnetostrictive wave-actuator techniques in preform infiltration processes for metal-matrix composite production is described. Metal matrix materials require additional methods to handle the content, shape and position of the ceramic reinforcements, which are not required for metal alloy casting. Commercial fabrication of advanced metal matrix composite products has
Artiodactyla (eved-toed ungulates) and Cetacea (whales) are two mammalian orders that are commonly recognised as sistergroups. Recently it has been suggested that Cetacea originated within Artiodactyla, but the relationships among the different artiodactyl lineages and Cetacea have not been conclusively established. In the present study the mitochondrial genome of the pig (Sus scrofa), the hippopo
In this thesis, three aspects of gene expression data analysis are discussed: Differential gene expression is addressed by a probabilistic method. Gene annotation enrichment analysis is discussed in the context of multiple hypothesis testing and the choice of null hypothesis. The possibility of inferring the activity of cellular signaling pathways from microarray data is explored. The methods deve
Modern theoretical simulations are able to provide significant insight into biochemical problems on a scale which continues to expand. With the aid of computer power and the sophisticated programs of researchers in the field, we have addressed a series of problems related to the so-called tetrapyrrole cofactors found in all living organisms. There have been three major challenges for us, all const
Interstitial laser thermotherapy (ILT) is a method well suited for selective local destruction of malignant tumours. In the present work, a laser thermotherapy system based on feedback temperature control of energy delivery (through computerised feedback system) was developed. Temperature control was excellent in experiments without carbonization and with preserved light penetration, whereas tempe
Sleep-related partial upper airway obstruction may cause increased morbidity and mortality, but diagnosis and treatment of patients is varying and inconsistent. The present studies were aimed to evaluate presently applied indirect methods for assessing respiratory ventilation and to investigate the value and accuracy in estimating upper airway resistance during sleep by measuring intrathoracic pre
Risk societies are made of risk organizations. This dissertation is an ethnographic study of a risk organization, of a nuclear power plant. Risk organizations have larger demands on their organization than traditional companies have. Risk societies, to come or already present, have new political agendas. Within a risk society the major task is to reduce and distribute the negative side effects of

If you are informed about research ethics, you can ask the right questions about what is appropriate or inappropriate in research. Research ethics is about both legislation and rules and good research practice. Ethical reviewAre you planning to do research that involves people or the processing of personal data? If so, you may need to seek ethical approval.More information about ethical reviewThe

Beundran för Maos Kina och inte minst för kulturrevolutionen betydde mycket för vänsteruppsvinget under 1960-talets senare hälft. Den växande konflikten mellan maoismen och sovjetkommunismen kom i hög grad att influera den svenska vänsterns utveckling och till sist sönderfall i olika fraktioner. Mao i Sverige följer den svenska maoismens utveckling steg för steg. Förutom att gå kronologiskt fram l
Friction stir welding (FSW) is a solid-state welding process where metals are joined without melting. Heat is generated by friction between a rotating non-consumable tool and the work-piece material, and by mechanical deformation of the material. The process, invented in 1991, provides several benefits over arc welding and other fusion processes: No filler material has to be added, low energy cons
Under tusentals år trodde människan att detta var Universums mittpunkt. Tack vare vår nyfikenhet, fantasi och lust att upptäcka, vet vi nu att planeter som vår Jord inte är särskilt ovanliga i kosmos. Solen är bara en vanlig stjärna bland hundratals miljoner andra i vår galax, Vintergatan.Med hjälp av världens mest kraftfulla teleskop kan vi utforska mer och mer av Universum. Det vi hittills har uFor thousands of years, mankind thought that this was the centre of the Universe. Thanks to our curiosity, imagination and urge to explore, we now know that planets like our Earth are nothing special in the cosmos. The Sun is just one ordinary star among hundreds of billions in our galaxy, the Milky Way.With the world’s most powerful telescopes, we are able to explore more and more of the Universe
Vi dyker tillsammans ner i tropiska hav och observerar tusentals färgglada fiskar simma förbi oss. Vi reser runt Jorden och undersöker olika typer av korallrev och de djur som där bor. Vi lär oss hur forskare tar fram nya metoder för att skydda och hjälpa Korallrevens Värld överleva nu när havstemperaturen stiger.Under vår resa upptäcker vi hur koraller lever, andas samt hur de förökar sig. KorallDive into a tropical ocean and see thousands of colorful fish flutter by. Travel the globe to explore coral reefs teeming with life and learn how scientists are racing to develop sustainable solutions to protect these vitally important ecosystems for the future. Along the way, discover how corals live, breathe, and reproduce, supporting a quarter of all marine life on Earth and providing critical
Högenergiastrofysik spelar en nyckelroll för vår förståelse av Universum. Den mest energirika strålningen avslöjar heta och våldsamma fenomen. Vi undersöker het gas i galaxhopar, som är de största och tyngsta objekten i Universum. Vi undersöker också het gas som samlas i skivor omkring supermassiva svarta hål i galaxers centra.Men högenergiastrofysik ger oss också viktig information om vår egen gaHigh Energy Astrophysics plays a key role in understanding the universe. These radiations reveal the processes in the hot and violent universe. High Energy Astrophysics probes hot gas in clusters of galaxies, which are the most massive objects in the universe. It also probes hot gas accreting around supermassive black holes in the centers of galaxies.Finally, high energy radiation provides importa
En el presente trabajo se presenta una investigación sobre las dificultades a las que se enfrentan estudiantes suecos de español como lengua extranjera (desde ahora ELE), a la hora de elegir entre los tiempos del pasado imperfecto e indefinido en relación con verbos de estado y de logro. El propósito de este estudio es describir, de manera general, la producción de errores para visualizar en qué m
In this paper I consider whether eudamonism—i.e. the thesis that the ultimate aim of human life and conduct is the attainment of happiness and that the achievement of this goal is closely linked to the acquisition and exercise of moral virtue and tranquillity of the soul—could serve as a framework for a theory of rights. I argue that the eudaimonist’s chances to ground a theory of rights from with
The argument in this paper is that Hobbes’ theory of freedom in Leviathan allows for four ways of being free to act – corporal freedom by nature, freedom from obligation by nature, the freedom to disobey, and the freedom of no-rule – each corresponding to a particular absence, some of which make sense only in the civil state. Contrary to what some have claimed, this complexity does not commit Hobb
