Popular Abstract in Swedish Mycket av dagens forskning inom astrofysik handlar på ett eller annat sätt om att förstå hur universum i allmänhet och vår galax i synnerhet fungerar. Var och hur har de grundämnen bildats som finns i stjärnor, planeter, gasmoln, på jorden och i våra kroppar? Det dominerande, och framgångsrika, sättet att ta reda på hur avlägsna astronomiska objekt ser ut och är uppbyggEta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. One such region, the strontium filament, is studied in more detail in this thesis, and the identities of 600 emission lines are reported. Some of these requi

Pancreas transplantation is today a technically successful procedure and provides an alternative to insulin injections for the treatment of Type I diabetes mellitus. This thesis was undertaken while pancreas transplantation was developing and while several fundamental questions were being asked about both endocrine and exocrine drainage of the transplanted pancreas as well as how best to diagnose

The Swedish National Road Administration SNRA is responsible for the long term de-velopment of the road transport system, and spends large sums on road construction and 'operation and maintenance'. Improvements in efficiency which are small in per-centage terms therefore yield relatively large monetary effects. In order to create and maintain a strong and competitive road construction sector and a

Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concent

Popular Abstract in English Popular Science Abstract In our daily routines, we use products and come across applications that involve mixtures of polymers and small amphiphilic molecules in water, for example detergents, pharmaceutics, foodstuffs, shampoos and paints. Polymers are very large molecules formed by smaller units that are repeated and connected. Amphiphilic molecules contain both one pThe research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising m

Boken innehåller en bred skildring av Ernst Jünger och hans närmaste vänkrets under slutfasen av Weimar-republiken. Bland de arbeten av Jünger som diskuteras återfinns "Das abenteuerliche Herz" (1929, "Die totale Mobilmachung" (1930) och "Der Arbeiter" (1932). Till persongalleriet hör Carl Schmitt, Ernst Niekisch, Friedrich Georg Jünger, Friedrich Hielscher med flera. Historien om Ernst Jünger och
