This thesis describes the physical chemistry of softwood kraft lignin in aqueous alkaline solutions. Both fundamental and applicational aspects are discussed. Kraft lignin originates either from pulp fibres or from black liquor produced by kraft cooking. In wood, the lignin is an anionic macromolecular colloid of relatively high molecular mass that is gradually depolymerised under the kraft cook.
The intention of this study is to question the supposed self-evident connection between sickness and sin in the individual complaint psalms. On the basis of a careful analysis of the psalms which contain the three motifs divine absence, divine wrath, and man’s guilt, the author problematizes this aspect of the exegetical literature’s widespread interpretation of the theological dimension of illnes
We analyze the effects of the increase in China’s import competition on Mexican domestic and international migration. We exploit the variation in exposure to competition from China, following its accession to the WTO in 2001, across Mexican municipalities and estimate the effect of international competition on the individual decision to migrate. Controlling for individual and municipality features
Popular Abstract in Swedish All materia består av atomer. Avhandlingen du just nu läser är uppbyggd av atomer; till och med du själv är uppbyggd av atomer. En kemist är intresserad av vilka atomer som hänger ihop för att bilda molekyler och hur dessa molekyler kan sammanfogas till fasta material. Man kan likna det vid att molekylerna är en byggsten som då de sammanfogas bildar en byggnadskonstruktHow do molecules arrange themselves in a crystal? It is today not possible to definite predict the three-dimensional packing arrangement of molecules in the crystalline solid state. The aim of the work presented in this thesis has been to gain more knowledge of what principles that govern molecular packing. Platinum(II) complexes have been chosen as model system since these compounds are stable,
Om svenska räddningsaktioner under andra världskriget och synen på dem efter 1945.
This article treats the organization and ideology of the Salamullah-movement in Indonesia, a New Religious Movement established in the post-Suharto era. A characteristic feature of the movement is its extensive usage of new technology in the dissemination of its religious ideas.
Popular Abstract in Swedish I Sverige produceras en stor del av elektriciteten i kärnkraftverk och som restprodukt får man ett mycket farligt radioaktivt avfall som måste isoleras från människor i hundratusentals till miljoner år. Svensk Kärnbränslehantering AB (SKB) har i uppdrag att ta hand om detta avfall och har utvecklat metoden KBS-3. I denna placeras det använda kärnbränslet i en kopparkapsBentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. Four field experiments were analyzed (Alternative Buffer Material experiment,
In the debate on the core of Information System (IS), El Sawy identified three faces of IS views: connection, immersion, and fusion. However, no research has further elaborated these concepts. For this task, we adopted the characteristics of the old concept of “emergence” to better describe and explain the shifts in IS from connection to immersion and finally towards fusion. A police organization
Popular Abstract in Swedish För att lungorna ska utvecklas normalt hos ett däggdjursfoster, måste lungorna vara vätskefyllda. Det har länge varit kännt att denna vätska produceras av lungorna själva, genom s k klorid-sekretion. Vid födelsen måste det nyfödda fostret börja andas och därför är det ytterst viktigt att lungorna snabbt töms på vätskan som fanns där under fosterutvecklingen. Detta sker Alveolar fluid clearance is driven by active absorption of Na+ across the alveolar epithelium. Development and hormonal regulation of alveolar fluid clearance over 1 hour was studied by instillation of a protein-containing, isosmolar fluid into lungs of fetal, newborn, and adult guinea pigs. After 1 hour, a sample of remaining alveolar fluid was collected and the change in protein concentration wa
This thesis describes analysis of data from the DELPHI Very Small Angle Tagger (VSAT) calorimeter at LEP1. The VSAT consists of four Silicon-Tungsten calorimeter modules symmetrically positioned 7.7 meters away from the interaction point. It measures elastically scattered electrons and positrons, Bhabha events, within the polar angular region between 5-12 mrad. Trigger efficiency and reconstructio
During recent decades women have made considerable advances in education and the labor market, even in fast-track professions such as law, medicine, and academia. While women have entered high-status professions, the career paths of some jobs have changed little and are still inflexible, which implies that professional gains may be offset by familial losses. We investigate continued childbearing,
Popular Abstract in Swedish Den farligaste formen av hudcancer, melanom, uppkommer genom okontrollerad tillväxt av melanocyter som är celler specialiserade i pigmentproduktion. Dessa celler skyddar oss från den farliga UV-strålingen med hjälp av pigment som omvandlar ljusvågor till värme. I Sverige drabbas drygt 2000 personer per år av sjukdomen. Cirka 80-85 % av dessa botas genom kirurgi men hos Melanoma is an aggressive disease that arises from deregulated signaling events in melanocytes. The KIT receptor tyrosine kinase and the Microphthalmia-associated transcription factor (MITF) are two essential components that are required for the normal physiology of melanocyte development and function. Consequently, aberrant activities of these factors are involved in the development of melanoma.
