This thesis focuses on the opera text enlightened from four different perspectives: the translator, the librettist, the composer and finally the singer, based on the author’s thirty years of professsional practice, in the spirit of Donald A. Schön’s study from 1983: The Reflective Practitioner; How professionals think in action. The method is basically hermeneutic and the esthetics inspired by Umb

Statistical analyses of the health effects of air pollution have increasingly used GIS-based covariates for prediction of ambient air quality in “land-use” regression models. More recently these regression models have accounted for spatial correlation structure in combining monitoring data with land-use covariates. The current paper builds on these concepts to address spatio-temporal prediction of

Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. These organic compounds are often semi-volatile and susceptible to oxidation which makes the organic aerosol a dynamic system, both chemically and physic

A remarkable insight into the life of every species Is it true that Penguins stay with the same partner for life? Why do most penguins keep stones in their stomachs? Why is a fat King Penguin male more attractive to the female? Penguins are fascinating animals: they cannot fly, they are awkward on land, but are as agile as fish under water. Their ability to survive in some of the coldest regions o

Popular Abstract in Swedish Avhandlingen handlar om den aspekt av människans självbild, eller självet, som på engelska kallas possible selves, och som på svenska skulle kunna kallas "möjliga själv" (en etablerad svensk översättning saknas). Detta är framtidsföreställningar eller framtidsbilder där vi ser oss själva i framtida situationer eller tillstånd, och teorin om möjliga själv presenterades fPossible selves are conceptions or images of ourselves in future states or situations. The theory about possible selves used in the present thesis was developed in a social cognitive tradition of research on the self, where the self is seen as a knowledge structure (Markus & Nurius, 1986). Possible selves are parts of this knowledge structure and possible selves are of importance for motivatio

Popular Abstract in Swedish Liksom du och jag, måste växter andas för att kunna leva. Med hjälp av luftens syre förbränns näring i form av bl a kolhydrater och fetter till koldioxid. Den energi som avges vid förbränningen omvandlas till ATP, som är cellens bränsle. Den huvudsakliga produktionen av ATP sker i den del av cellen som kallas mitokondrien, cellens kraftverk. Vän av ordning kliar sig nu In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. Database screening of the Arabidopsis genome identified seven type II NAD(P)H dehydrogenase homologues of which two and four genes were closely related to potato (Solanum tube

In this paper, we derive an Expectation-Maximization algorithm for hidden Markov models (HMMs) with a multivariate Rayleigh mixture model (RMM) in each state. We compare the use of multivariate RMMs to multivariate Gaussian mixture models in the general case where the HMM is a dynamic model and for the special case where it has a single state and reduces to a static model. We evaluate the proposed
