Popular Abstract in Swedish Joniserande strålning- en introduktion (Ionizing radiation- Introduction in Swedish) 13.1 Storheter och enheter Effekten av strålningen från ett radioaktivt ämne eller röntgenapparat kallas stråldosen, eller egentligen den effektiva dosen , och anges i enheten sievert (Sv). Aktiviteten av ett radioaktivt ämne anges i enheten becquerel (Bq) och anger antal sönderfallanIn this thesis quantitative analyses of radionuclide concentrations in bioenergy fuels such as peat, wood chips and straw are presented. For comparison a brief description is included of radionuclide concentrations and radiation doses from other sources of power and also from some industrial applications. Radiation is a natural phenomenon and radionuclides occur naturally. The first man-made spre

The paper gives an account of the concept of 'hapiness' and 'felicity' in the discourse of 18th century thought.

Popular Abstract in Swedish Denne populationstudie om kataraktkirurgi strakte sig over en pre- og peroperativ fase med indsamling af data i perioden 1986-1990. Den postoperative dataindsamling i denne redegørelse dækker perioden 1986-1992. Epidemiologiske forhold belyses i det første og syvende arbejde. Anatomiske og især refraktive forhold bliver belyst i den andet og tredje publikation. Det fjerThere has been a striking increase in the number of cataract operations in the referral region of the Lund Health Care District during 1986 through 1990, in 1990 reaching 3.6 per 1000 inhabitants. Different preoperative, intraoperative and postoperative variables and observations were registered and analysed for 5878 consecutive cataract cases operated in the period studied. Women predominate in t

Popular Abstract in Swedish Ekonomisk teori delar ofta in ekonomin i olika tidshorisonter, som till exempel kortsikt, medelfristigsikt och långsikt. Det är ofta enklare att empiriskt studera modeller med många tidshorisonter i frekvensdomänen än i tidsdomänen eftersom varje horisont representeras av en specifik frekvens eller ett band av frekvenser. Denna avhandling använder wavelet analys för attEconomic theory commonly distinguishes between different time horizons such as the short run and the long run. Models with many time horizons are easily studied in the frequency domain, because the various time horizons are associated with a particular frequency or band of frequencies. This dissertation studies wavelet methods to analyze time series. Wavelet transforms combine time and frequency r

Environmental change may affect predator-prey interactions in lakes through deterioration of visual conditions affecting foraging success of visually oriented predators. Environmental change in lakes includes an increase in humic matter causing browner water and reduced visibility, affecting the behavioural performance of both piscivores and prey. We studied diurnal patterns of prey selection in p

We present a new method for manufacturing complex-valued harmonic morphisms from a wide class of Riemannian Lie groups. This yields new solutions from an important family of homogeneous Hadamard manifolds. We also give a new method for constructing left-invariant foliations on a large class of Lie groups producing harmonic morphisms.

Increased red cell distribution width (RDW) has been related to poor prognosis in patients with cardiovascular disease, and is a predictor of cardiovascular mortality in the general population. The purpose of the present study was to investigate if RDW is associated with increased incidence of stroke and its subtypes in individuals from the general population.

Let H be a Hilbert space of analytic functions with multiplier algebra M(H), and let M = {(f, T(1)f, ... ,T(n-1)f) : f is an element of D} be an invariant graph subspace for M(H)((n)). Here n >= 2, D subset of H is a vector-subspace, T-i : D -> H are linear transformations that commute with each multiplication operator M-phi is an element of M(H), and M is closed in H-(n). In this paper we investi

The acquisition of multispectral x-ray images and the treatment of such data are essential for understanding many devices that we encounter in everyday life. Examples include computerized tomography in hospitals and scanners at airports. X-ray devices remain impractical for undergraduate laboratories because of their considerable cost and the risk of exposure to ionizing radiation. One way to acqu

This paper introduces a novel approach to building virtual laboratories of embedded control systems using TrueTime and Easy Java Simulations. TrueTime is a freeware MATLAB/Simulink based tool commonly used to simulate embedded control systems. Easy Java Simulations is a popular authoring tool that facilitates the creation of pedagogical simulations. According to the proposed approach, authors use

Since the 1990s, vigorous debate concerning a number of key issues has taken place within the study of Chinese nationalism. Scholars have tended to differentiate between diverse types of nationalism. For example, many studies distinguish between a malign nationalism on the one hand and a benign patriotism on the other. The strongest evidence for such a distinction can be found in survey research,

The phase behavior of systems containing sodium alkyl polypropylene oxide sulfate with equimolar ratio of polypropylene oxide ammonium chloride was determined as a function of salt concentration and alkane carbon number at ambient temperature. Visual inspection as well as cross polarizers were used to detect anisotropy. Solubilization ratios for oil and brine in the middle phases were measured and
