The Russian modernisation as a conscious policy started with Peter I. It was resumed time after time by a succession of Russian rulers, from Catherine II to Mikhail Gorbachev. The article places this story in the context of historical culture and narration. The paper is not about any history as such. It is a suggestion how to make sense of one dimension of Russia’s history: the St. Petersburg stor
Rättsläget när det gäller att få en godkänd arbetsskada efter utmattningssyndrom är synnerligen oklart, och det är snarare regel än undantag att dessa ärenden avslås. Vi beskriver hur ett sådant ärende bedömts av Försäkringskassan och Länsrätten. Ärendet gick inte vidare till Kammarrätten, eftersom försäkringskassan godtog Länsrättens dom. Därmed är inte domen vägledande rent juridiskt, men utslag
The induction of cyclobutane pyrimidine dimers (CPDs) by ultraviolet-B radiation (UV-B, 280-315 nm) and repair mechanisms were studied in the lichen Cladonia arbuscula ssp. mitis exposed to different temperatures and water status conditions. In addition, the development and repair of CPDs were studied in relation to the different developmental stages of the lichen thallus podetial branches. Air-dr
Abstract in UndeterminedUnless the basic user needs are satisfied in safety helmets, it is difficult to get workers to wear them habitually and for long periods. Hotness, weight and fitting problems are major wearability issues that require improvements. The enormous need for an optimally designed helmet in China prompted a case study on comfort aspects in helmets. The subjective impressions of th
Aims: A study was undertaken to assess the impact of social participation, trust and the miniaturization of community, i.e. high social participation/low trust, on two measures of patient dissatisfaction in primary healthcare. Methods: The Scania 2000 public-health survey is a cross-sectional, postal questionnaire study. A total of 3,456 persons aged 18-80 years who had a regular doctor within the
In this correspondence, we extend the recently introduced one-dimensional Capon-based Magnitude Square Coherence (MSC) spectral estimator, to form two-dimensional Capon- and Amplitude and Phase EStimation (APES)-based MSC spectral estimators. The resulting estimators are found to yield significantly improved estimates as compared to the typical Welch-based estimator. Furthermore,, we introduce a c
Four wastewater samples of different treatment qualities; untreated, alarm, alert and normal, from a Swedish chen-ti-thermo-mechanical pulp mill and pure water were investigated using an amperometric bioelectronic tongue in a batch cell. The aim was to explore enzymatically modified screen-printed amperometric sensors for the discrimination of wastewater quality and to counteract the inherent drif
The focus of this thesis is on modeling and control of the Open Plate Reactor (OPR), a new heat exchange reactor being developed by Alfa Laval AB. It combines intensified mixing with enhanced heat transfer capacity into one operation. With the novel concept, highly exothermic reactions can be produced using more concentrated reactants, thus saving time and energy in the subsequent separation stage
The structure of Kr-72 has been investigated at GASP through the Ca-40(Ca-40,2 alpha) reaction at a beam energy of 160 MeV using the 4 pi ISIS Si-ball for reaction channel selection. The level scheme has been extended up to an excitation energy of approximate to 8.5 MeV. The spins and parities of the observed levels are assigned tentatively. The observed band shows the predicted change from oblate
The major aim of this study was to investigate the CYP3A4 metabolism and polarized transport of ropivacaine and its metabolite 2',6'-pipecoloxylidide (PPX) in tissue specimens from the human small and large intestine. Ropivacaine has been shown to be effective in the treatment of ulcerative colitis in human colon. This study was conducted using a modified Ussing-chamber technique with specimens fr
PURPOSE: The aim of this study was to investigate the outcome of aortic valve replacement (AVR) and the effect on quality of life in patients aged over 85 who had symptomatic aortic stenosis. METHODS: We performed a retrospective analysis of 21 patients, aged 85-91 years (mean age 86.5), who underwent AVR, 10 of whom underwent concomitant coronary artery bypass grafting (CABG) between 1989 and 199
The mechanisms by which glucagon-like peptide 1(7-36)amide (GLP-1[7-36]amide) potentiates insulin secretion were investigated by measurements of whole-cell K+ and Ca2+ currents, membrane potential, the cytoplasmic Ca2+ concentration ([Ca2+]i) and exocytosis in mouse pancreatic B-cells. GLP-1(7-36)amide (10 nM) stimulated glucose-induced (10 mM) electrical activity in intact pancreatic islets. The
The theory and applications of chaotic oscillators in electronic commuication are investigated. A method of random number generation utilising a chaotic double scroll oscillator is proposed and evaluated. The theoretical limits of the randomness of the method is analysed.
