Small words like ‘yes’ and ‘no’ play an important part in our daily communication, but do we clearly know where they come from? Their origin is rather mysterious. We do not know if we need these words at all, since some languages manage without them. For instance, speakers of Celtic languages answer affirmatively and negatively by repeating verbs. However, functional motivations to have ‘yes’ and

Popular Abstract in Swedish Trots omfattande forskning är förståelsen för diffus hjärnpåverkan efter hjärtkirurgi och dess kliniska betydelse ofullständig. Avhandlingens syfte har varit att kartlägga kognitiv funktion efter kranskärlskirurgi och undersöka de kliniska konsekvenserna därav. Med neuropsykologiska test, intervjuer och frågeformulär har patienters subjektiva och objektiva kognitiva fuDespite considerable research efforts, the incidence and mechanisms of diffuse cognitive impairment after coronary artery bypass surgery are not fully understood. The aim of the dissertation was to describe cognitive changes after coronary artery bypass grafting (CABG) and the predictors and consequences thereof. Neuropsychological tests, interviews and questionnaires were used to assess objectiv

Popular Abstract in Swedish DNA är en molekyl som finns närvarande i stan alla celler och den innehåller den genetiska koden för utvecklingen av alla former av liv. Molekylen är väldigt tunn (2 nanometer i diameter) och lång - mänskligt DNA skulle vara ca en meter lång i utsträckt tillstånd. Inuti cellerna antar DNA en superkompakt struktur för att få plats inuti en cellkärna med bara ca 10 mikromThe structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. The effect is a strong association of DNA with the oppositely charged amphiphile resulting in the form

During the 1980s and the 1990s several researchers have described new organisational features and a new organisational form in multinational enterprises, linked to a variety of theoretical approaches. Can the new organisational features be analysed from a consistent theoretical basis, and can, hereby, a new organisational form be distinguished from earlier forms? The purpose of this dissertation i

The liberalised electricity market in Sweden stresses the fact that the electricity companies must focus on customer satisfaction. Two major customer surveys concentrating on households’ requirements concerning the electricity bill have been carried out in spring 2002. The interest in energy management lies within the fact that the electricity bill can be used as a feedback instrument to influence

Popular Abstract in Swedish Under de senaste tjugo åren har omfattande arbete och resurser lagts ner på basforskning inom termokemisk omvandling av alternativa bränslen och dess tillämpningsområden. De termokemiska omvandlingsprocesserna här avser närmast s k pyrolys- och förgasning-processer vilka till stor del är baserade på teknik hämtad från kolforskningen. Idag görs försök att finna vägar attDuring the past twenty years, considerable efforts have been invested in fundamental research on the thermochemical conversion of alternative solid fuels and on its areas of application. Today, the attempt is being made to develop processes for upgrading those fuels to become easy accessible energy sources of high efficiency. The thesis concerns thermochemical means for utilizing biomass. Light i

This paper investigates the impact of the completion of the liberalized European Internal Electricity Market on Integrated Resource Planning (IRP) and Demand-Side Management (DSM). The results presented are part of the outcomes of a study analyzing the possibilities of IRP and DSM in this new industry environment. The study, finished in May 2000, is based on empirical surveys of both the present a

Small rodents were captured in two regions in western Sweden. One represents an agricultural landscape were captures were made in 19 small habitat islands and in two small forests. The other represents a forest region were captures were made in four sites in a continuous forest. The captures were made for seven years. There were no clear indications of cyclicity. Within both regions, wood mice cap
