The load response during and after a severe fault is critical for transient stability. This risk increases with the presence of induction motors in the load area. This paper provides analysis of the load voltage characteristic under large voltage variations. Field measurements from a noneffectively earthed system, from phase-to-phase faults at the 50 kV-level in Sweden, have been used. The time-va
This book studies the technognomies of memory in scripto as in texts, lists, dictionaries and databases and less the technognomies of memory in vivo (as in remembering). There are of course some relations between these two kinds of memories, being memory-in-scripto a development parallel to the development of written language. We notice that the historical presentation is built upon both forms of
Aviation fuel is a petroleum product that fulfills the Standard Specification for Aviation Turbine Fuels. Crude oil has been the raw material for production of aviation fuels for many years. Since the availability of crude oil is predicted to be limited in the future, alternative raw materials for aviation fuels are highly desirable. A Swedish company, Oroboros AB, has developed a novel clean synt
Popular Abstract in Swedish Redoxreaktioner är centrala i många livsnödvändiga funktioner såsom anabol och katabol metabolism. Det är därför viktigt att känna av och reglera cellens redoxstatus. En viktig komponent som påverkar detta är tillgången på syre. När syretillgången förändras så förändras den intracellulära redoxstatusen, vilket genererar en stress för cellen. Denna stress leder till ett Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. Transitions between different oxygen concentrations change the redox status and among other things, confer a stress upon the cells. This s
Popular Abstract in Swedish Under de senaste 20 åren har större hänsyn tagits till den enskilde patientens önskningar och behov innan en behandling har påbörjats. Detta har skett parallellt med en snabb teknisk och medicinsk utveckling. Samtidigt som nya behandlingsmetoder tagits fram, har det också blivit angeläget att utvärdera effekten av dessa, vilket även inkluderar hur den enskilde individenFactors determining patient`s and doctor`s delay in diagnosis of bladder cancer were type of initial symptoms, level of health service first consulted and number of steps in the referral system. No correlation was found between psychosocial factors and patient`s delay. In retrospective studies after cystectomy for bladder cancer, patients with continent cutaneous diversion of urine had fewer stoma
This study argues that Vietnamese girls' socialization is inseparable from the symbolic and biological meaning of female and male bodies. Socialization is not so much about "sex" (i.e. biological sex) or "gender" (i.e. social/symbolic sex) as it is about "body". This argument is elaborated theoretically with regard to contemporary research on the body and empirically with respect to a local north
Objective: Evaluate the impotrtance of incomplete gelatinization, food structure and presence of viscous dietary fibre for the postprandial glycaemic and insulinaemic responses to oat and wheat products. Design: Three common breakfast meals were tested, "raw" rolled oats (muesli), boiled rolled oats (oat porridge) and white wheat bread. Boiled intact oat and wheat kernels (kernel porridges) were a
This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. Important functional residues can be identified by mutational analysis. There is a need for rapid methods to study prot
We give a new proof of the Nirenberg-Treves conjecture: that local solvability of principal type pseudodifferential operators is equivalent to condition (Psi). This condition rules out sign changes from - to + of the imaginary part of the principal symbol along the oriented bicharacteristics of the real part. We obtain local solvability by proving a localizable a priori estimate for the adjoint op
