Cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution, origin of cellulose and properties are importaint in order to design processess so as to produce derivatives with the desired properties. This thesis describes research on newly developed analytical methods for the analysis of

Popular Abstract in Swedish Djurs förmåga att hitta då de förflyttar sig långa sträckor mellan fortplantningsområden och övervintringsområden har fascinerat människor i hundratals år. Det finns flera olika teorier kring hur djur navigerar, till exempel med hjälp av dofter, landmärken, solen, polariserat ljus, stjärnorna eller jordens magnetfält. Att djur skulle kunna använda sig av just jordens maMigration research is a large and diverse field and in my thesis I have focused on the impact of geomagnetic cues on animal orientation, navigation and migratory fuelling. Several animal species from widely different taxa possess the ability to sense and make use of geomagnetic information during migratory or homing events. I used a map showing isolines for magnetic total field intensity and incl

Popular Abstract in Swedish Under de senaste decennierna har det pågått en intensiv kamp om dramapedagogikens innehåll. Den har i betydande utsträckning förts på nordiskt plan. Dramaläraren och lärarutbildaren Viveka Rasmusson visar att denna debatt om dramaämnet och dess utveckling med fördel kan studeras i den nordiska tidskriften Drama. Under större delen av sjuttiotalet var Drama ett gemensamtBased on the Nordic dramapedagogic journal Drama during the period 1965-1995 the thesis analyses Nordic dramapedagogy and the dramatheoretical debate of the subject drama, which entered Nordic school curriculums in the sixties and the seventies. During the period a struggle was fought by predecessors from different aestethic and pedagogical directions concerning the definition of the subject. The

It is shown that the high-resolution laser photoelectron microscope withsubwavelength-spatial resolution can be used for an absolute values ofthe two-photon external photoelectric effect measurements with high (afew nm-scale) localization. The spatial distribution of light intensityin the near field is studied by observing the photoelectron projectionimages of a subwavelength nanoaperture. The ima

Popular Abstract in Swedish Huden och slemhinnor (mukosa) fungerar som kroppens skyddsbarriärer mot yttre angrepp av mikrober, makromolekyler och toxiner och förhindrar dessa att nå inre organ. Trots ett massivt immunskydd sker de flesta infektioner på slemhinnornas ytor. I blodcirkulationen förekommer fem olika typer av vita blodkroppar, alla med olika roller i immunförsvaret. I varje blod finns Mucosal infections trigger an inflammatory response that includes the secretion of cytokines and the recruitment of neutrophils to the infected site. This thesis describes studies examining the molecular mechanisms of neutrophil migration to sites of mucosal bacterial infection. Escherichia coli (E. coli) infection of epithelial cell layers stimulates chemokine secretion and chemokine receptor ex

The basic hypothesis is that mind is an emergent property of the processes that produce natural language expressions. The shape of the mind of a particular person can be discovered through the mechanisms forming the corresponding language space. Although covered by textual surface properties, this space is approachable with VERTEX, which is a new version of Perspective Text Analysis (PTA). Due to

Resistance to antibiotics is a major threat to the effectiveness of modern health care. This study examines if pay-for-performance (P4P) to care providers stimulates the appropriate use of antibiotics; in particular, if P4P can induce a substitution away from broad-spectrum antibiotics, which contribute more to the development of resistance, to less resistance-driving types. In the context of Swed

This article analyses the history of the Swedish welfare state, with a special emphasis on the development of Swedish family policy between 1930 and 1975. It is argued that a coalition between state officials and state-appointed experts was active in the shaping and legitimising of the concept of family as well of family politics. The underlying assumption of the paper is that the concepts of the

Galiellalactone is a fungal metabolite found in the basidiomycetes Galiella rufa and the unidentified strain A111-95. It has been shown to possess promising activities as an inhibitor of the IL-6 mediated STAT3 signaling in HepG2 cells. Targeting this pathway is very important when it comes to understanding intracellular signaling and also for developing drugs for treating diseases associated with
