Popular Abstract in Swedish Den första delen av denna avhandling behandlar teoretiska aspekter på stärkelsens kristallina egenskaper. Vår förståelse av dessa egenskaper är baserad på modeller som erhållits via kristallografiska undersökningar av modifierad amylos. Mycket tyder på att dessa modeller är direkt överförbara till amylopektin som utgör den kristallina komponenten i stärkelse. En stor deThe crystalline properties of starch constitutes a puzzling area of research. Our understanding of the crystalline structure of amylopectin, that is the crystalline component in starch, is based on the observations from investigations on modified amylose. The first part of this thesis includes a discussion of the unit cells (the smallest crystalline units) suggested in the literature. The differen

In recent years the market for biopharmaceutical products has been increasing rapidly as a result of an increased demand for new and efficient treatments of various indications. Biopharmaceuticals are distinguished from chemical drugs by being derived from a biological origin and are hence, frequently constituting biological macromolecules. With the emergence of recombinant DNA technology, today m

The subgraph homeomorphism problem is to decide whether there is an injective mapping of the vertices of a pattern graph into vertices of a host graph so that the edges of the pattern graph can be mapped into (internally) vertex-disjoint paths in the host graph. The restriction of subgraph homeomorphism where an injective mapping of the vertices of the pattern graph into vertices of the host graph

Utgångspunkten för denna studie har varit studenten och dennes motivation för att lära och förbereda sig inför ett yrkesliv som civilingenjör. Vi konstaterar att man i planering och genomförande av en kurs bör ta hänsyn till de olika behov som finns hos studenten, läraren, lärarteamet, avdelningen/institutionen, andra kurser, universitetet och dess uppdragsgivare, samt näringslivet och samhället i

Introduction P-32 phosphate was the first therapeutic radioisotope, used in leukaemia about 70 years ago. Since then, many new agents for haematological proliferations have been introduced successfully. Today there remains a distinct subgroup of elderly patients with polycythaemia vera and essential thrombocythaemia for whom P-32 is the most optimal treatment option, an assertion supported by two

The salamander Ensatina eschscholtzii Gray is a classic example of a ring species, or a species that has expanded around a central barrier to form a secondary contact characterized by species-level divergence. In the original formulation of the ring species scenario, an explicit biogeographical model was proposed to account for the occurrence of intraspecific sympatry between two subspecies in sou

Shifting the resource base for chemical production from fossil feedstocks to renewable raw materials provides exciting possibilities for the use of industrial biotechnology-based process tools. This review gives an indication of the current developments in the transition to bio-based production, with a focus on the production of chemicals, and points out some of the challenges that exist in the la
