Hydrophobically Modified Polymers. Rheology and Molecular Associations
Popular Abstract in Swedish Vattenbaserad målarfärg är ett exempel på en vattenlösning som måste förtjockas för att den skall uppföra sig som vi vill. I en färg med för låg viskositet sjunker alla partiklar snabbt till botten på burken och när man målar kan man bara ta lite färg i penseln om inte färgen skall droppa. För att färgen skall få rätt viskositet tillsätts vattenlösliga polymerer. En braStructure- property relationships and thickening mechanism in aqueous solution of two hydrophobically modified polymers (HM-P) with different architecture have been investigated. The two polymers, hydrophobically modified ethyl hydroxyethyl cellulose (HM-EHEC) and hydrophobically modified polyethylene glycol (HM-PEG), are commonly used as associative thickeners in the paint industry. The strength

Acoustic Energy Generated by Convection: 3-D Numerical Simulations for the Sun
Dissipation of acoustic waves may be an efficient heating mechanism forthe lower and middle chromosphere of the quiet Sun. The basic idea isthat turbulent motions at the top of the solar convection zone generateacoustic waves which propagate upwards and dissipate in the lower andmiddle chromosphere, transporting energy into the higher layers. Butstill the question remains if this amount of energy

Anorexia nervosa 6 years after onset: Part II. Comorbid psychiatric problems
A sample of anorexia nervosa (AN) cases recruited after community screening were contrasted with an age-, sex-, and school-matched comparison (COMP) group with regard to comorbidity at age 21 years, approximately 6 years after the reported onset of the eating disorder. Both groups had originally been examined at age 16 years. Most of the AN cases no longer met criteria for AN, but many continued t
Seaside, Celebration och Windsor: Studier av urbana estetiska regler
Popular Abstract in Swedish Det finns idag en uttalad strävan från samhällets sida att höja den arki-tektoniska kvaliteten i den byggda miljön. Den svenska bygg-lagstiftning-en är sedan ett par år tillbaka ändrad så att hänsyn måste tas också till estetiska kvaliteter när ändringar i den fysiska miljön ska genomföras. I den regerings-proposition som föregick lagändringen pekas arkitektur och desigThis dissertation deals with aesthetic rules in an urban context. The dissertation develops a theoretical framework for understanding the role of aesthetic rules, especially urban design codes, in the process of improving the architectural quality of the built environment. In the context of this framework three case studies of urban design codes are presented. The over-arching aim is hermeneutical
On Analysis and Synthesis of Safe Control Laws
Controller synthesis for nonlinear systems is considered with the following objective: No trajectory starting from a given set of initial states is allowed to enter into a given set of forbidden (unsafe) states. A methodology for safety verification using barrier certificates has recently been proposed. Here it is shown how a safe control law together with a corresponding barrier certificate can b

Enzymatic and Immunological Detection Principles for Environmental and Biological Applications
The aim of the thesis was to develop new analytical detection principles based on enzymatic and immunological reactions for sensitive, selective, cost-effective and high sample through-put detection devices. The thesis presents the basic elements and reaction paths necessary for the construction and development of enzyme based amperometric biosensors and immunoassays. The developed biochemical det

Lyckans betydelse : sekularisering, sensibilisering och individualisering i svenska skillingtryck 1750–1850
This dissertation takes its departure from the methodology of German Begriffsgeschichte and sets out to explore the use of the concept of happiness in Swedish chapbooks (skillingtryck).The period considered, 1750-1850, frames the transition from early modern to modern society, a time that has often been labeled Sattelzeit or Schwellenzeit. The aim of this thesis is to study how the concept of happ

Fungal Lectins. Molecular structure and function of a member of a novel lectin family.
Popular Abstract in Swedish En typisk egenskap för de flesta proteiner är att de kan binda specifikt och reversibelt till olika ämnen. Välkända exempel är enzymer som kan binda till olika substrat och inhibitorer samt antikroppar som binder till antigen. Under min tid som doktorand vid avdelningen för mikrobiologisk ekologi vid Lunds universitet har jag studerat en grupp av proteiner i svamp som kLectins defined as non-enzyme, non-immunoglobulin carbohydrate binding proteins, have been found in a wide variety of viruses, bacteria, fungi, plants and animals. Although lectins have been purified from more than 60 different species of fungi, the structure and biological functions of these proteins are not well known. I examined the molecular structure of a lectin (designated AOL) isolated from
Synthesis of the Monodeoxy Neoglycolipid Analogues of Globotrioside; Development of Some New Methods in Carbohydrate Chemistry.
1. All monodeoxy TMSEt globotriosides (GbO3) and double-chain bis-sulfone GbO3-lipids were synthesised. The alpha-glycosylation with deoxygenated glycosyl donors (fluoride, ethylthio- and thiopyridin-2-yl-) was investigated in the syntheses of the TMSEt 2"-, 3",- 4"- and 6"-deoxy GbO3, and activation of the thiopyridin-2-yl-glycosides with AgOTf gave the best yield and selectivity. Glycosylation w

Rehabiliteringskliniken 1962 -1992
Min berättelse börjar med ett telefonsamtal i början på sommaren 1976, från Chefarbetsterapeuten på Universitetssjukhuset i Lund. Hon frågade om jag ville börja arbeta på Rehabiliteringsklinikens dagavdelning i Lund, med början i augusti. Jag skulle i samma veva just ringa besked till sjukhuset i Boden, där jag varit och tittat på jobb under sommaren. På 1970-talet var det vanligt att sjukhus i No
Linear and Nonlinear Transport in Quantum Nanostructures
Popular Abstract in Swedish Den här avhandlingen beskriver elektrontransport i nanometerstora halvledarstrukturer vid mycket låga temperaturer (1 nanometer = 1 miljondels millimeter). De här strukturerna har helt andra elektriska egenskaper än vanliga ledare. Man ser effekter av enskilda elektroners transport, och av kvantmekaniska fenomen som kvantiserad energi och våginterferens. Området är föreIn this thesis, electron transport in mesoscopic semiconductor nanostructures, in particular so-called electron billiards or quantum dots, is studied. The thesis can be divided into two areas: the linear response regime of transport, and the nonlinear response regime of transport. The classical and quantum mechanical electron dynamics are studied for triangular and square-shaped electron billiard
