Pancreas Transplantation: Development of Successful Preclinical Models

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

Konkurrens, anbudsvärdering och entreprenörernas innovativa agerande inom vägbyggnadssektorn

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

Reactors and biosensors for improved microbial degradation of acetonitrile

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

Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

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

Preussiska anarkister. Ernst Jünger och hans krets under Weimar-republikens krisår

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

Efficiency, gain and Q of antennas

The fundamental limits of the gain, efficiency and Q-value of an antenna put severe restrictions on small antennas. In this paper it is discussed how one can avoid low efficiency and high Q-values in small antennas by examining the far-field pattern of the antenna. The analysis is based on the expansion of the electromagnetic fields in terms of vector spherical harmonics. © 2007 IEEE.
