New calorimetric methods for direct measurement of solubility and solvent activity are presented. The classical role of calorimetry for measurements of enthalpic parameters is abandoned and the technique is instead used for assessing thermodynamic quantities related to the chemical potential of a substance in a solution. Isothermal calorimetry is here employed as a general analytical method where
In this article the problem of explicit description of commuting functions of noncommuting elements satisfying commutation relation of the form AB = BF(A) is considered and connection to periodic points of corresponding dynamical system is established.
The official publication of the International Society for the Study of the Lumbar Spine, this volume is the most authoritative and up-to-date reference on the lumbar spine. This edition provides more balance between basic science and clinical material and has been completely reorganized for easy reference. New chapters cover gene therapy, outcomes assessment, and alternatives to traditional nonop
Total offers have become increasingly common in the aircraft industry during recent years. The total offers bring on challenges as well as possibilities for the providers of engine maintenance. The possibilities, increased profitability and efficiency, are depending on how the organisation copes with the challenges. An important challenge is the transfer of risk that occurs in a fixed price situat
Popular Abstract in Swedish Inom industrin används många olika kemikalier. Många av dessa kan förorsaka mer eller mindre allvarliga hälsoproblem. För att kunna mäta exponeringen och förutsäga riskerna måste bra metoder för övervakningen utvecklas. Idag användes mest olika luftövervakningsmetoder men dessa har brister då upptaget är individuellt och bland annat beror på arbetsbelastningen. DessutomN-methyl-2-pyrrolidone (NMP) is an organic solvent widely used in the industry. Irritation of the eyes and in the respiratory system has been reported after occupational exposure to low air levels of NMP. The EU has also classified it as a developmental toxicant. NMP is easily absorbed in the gastrointestinal tract and airways and through skin. The general aim of this thesis was to develop
Glucosinolates are natural plant products that function in the defense toward herbivores and pathogens. Plant defense is regulated by multiple signal transduction pathways in which salicylic acid (SA), jasmonic acid, and ethylene function as signaling molecules. Glucosinolate content was analyzed in Arabidopsis wild-type plants in response to single or combinatorial treatments with methyljasmonate

This thesis investigates the female novel of development as a specific genre, focusing on Swedish 20th century literature. In the first three chapters, three trilogies are examined, namely Agnes von Krusenstjerna's series about a titled girl (I922-26), Irja Browallius' novels about a foster girl (1957-61), and Ingrid Sjöstrand's series of collective novels about a group of girls from a girls' scho
