Boundary finding in simulated medical images is performed by optimizing the Fourier coefficients in a parametric surface representation with respect to an objective function. The deformable model is fitted to the data using the brightness gradient component which is normal to the surface. A low order (<10) Fourier series expansion offers a sufficiently accurate representation for many inherently s
Objective: To evaluate under- and overreporting and their determinants in the EPIC :24-hour diet recall (24-HDR) measurements collected in the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: Cross-sectional analysis. 24-HDR measurements were obtained by means of a standardised computerised interview program (EPIC-SOFT). The ratio of reported energy intake (EI) to estim
En undersökning av hur romaner har använts i högskoleutbildning (svenska och litteraturvetenskap), med exemplet Växjö högskola/universitet, under åren 1971-2003. Scheman, litteraturlistor och kursplaner står i fokus för analyserna.
[1] Methane fluxes were measured at five sites representing oligotrophic peatlands along a European transect. Five study plots were subjected to elevated CO2 concentration (560 ppm), and five plots to NH4NO3 (3 or 5 g N yr(-1)). The CH4 emissions from the control plots correlated in most cases with the soil temperatures. The depth of the water table, the pH, and the DOC, N and SO4 concentrations w
Oxidative stress has been ascribed a role in the pathogenesis of diabetes and its complications, and stress proteins have been shown to protect organisms in vitro and in vivo against oxidative stress. To study the putative role of one of the most abundant cytoprotective stress proteins, inducible cytoplasmic 72-kDa-mass heat shock protein (Hsp-72), in the pathogenesis of diabetes, we measured its
The purpose of this project was to help bridge the gap between developers and residents by creating a design criteria checklist for outdoor residential areas and to validate the checklist by means of a post-occupancy evaluation (POE) carried out by the residents in six housing areas. Items addressed in the checklist covered general layout, complexity and coherence, identity and affection, construc
February 22, 1756, exactly 250 years ago, died one of Linnaeus’ apostles, the Swede Pehr Löfling, at the missions of San Antonio de Caroní, Venezuela. He was buried under an orange tree, just 27 years old. Sent by Linnaeus to participate in a Spanish border expedition, led by José de Iturriaga, he had the task to explore the flora and fauna of the New World. After spending more than two years in S
In the present work we study the 1s2s2p3 6S(o) --> 1s2s2p(2)3s6P(e) and 1s2s2p3 6S(o) --> 1s2s2p(2)3d6P(e) transitions energies and probabilities in the boron isoelectronic sequence, including B I, C II, N III, O IV, F V, Mg IX and Al IX. Extending the calculations to Be-, we also confirm the bound character of the excited 1s2s2p3 6S(o) state and predict the electron affinity EA = 1.29783eV for Be
Informed product choices are,a prerequisite for the greening of consumption. Nordic consumers are subject to an ever-growing amount of product-related environmental information that is available in a number of formats. The degree to which they use information is disputed. This paper reviews Nordic research on consumer perceptions, understanding and use of product-related environmental information.
The most economical way to convert truck and bus DI-diesel engines to natural gas operation is to replace the injector with a spark plug and modify the combustion chamber in the piston crown for spark ignition operation. The modification of the piston crown should give a geometry well suited for spark ignition operation with the original swirling inlet port. Ten different geometries were tried on
The expression and activities of constitutive nitric oxide synthase (cNOS) and inducible nitric oxide synthase (iNOS) in relation to insulin and glucagon secretory mechanisms were investigated in islets isolated from rats subjected to total parenteral nutrition (TPN) for 10 d. TPN is known to result in significantly increased levels of plasma lipids during the infusion time. In comparison with isl
Popular Abstract in Swedish Kvinnor mot krig. Aktioner och nätverk för fred 1914-1940. Syftet med avhandlingen är att undersöka varför och på vilket sätt kvinnor skapade fredsaktioner under första världskriget och mellankrigstiden. Jag har studerat hur kvinnor mobiliserades, hur aktionerna genomfördes, vilket motstånd som väcktes och vad som hände efteråt. Utgångspunkten är kollektiva aktioner, soThe aim of this dissertation is to investigate how and why women established peace actions during World War I and the period between the wars. I have examined how women were mobilized, how the actions were carried out, what kind of opposition was awakened, and what happened afterwards. My startingpoint is collective actions based on individual standpoints and temporary mobilizations. Organizations
A 20-l packed-bed reactor filled with foamed glass beads was tested for the treatment of acetonitrile HPLC wastes. Aeration was provided by recirculating a portion of the reactor liquid phase through an aeration tank, where the dissolved oxygen concentration was kept at 6 mg/l. At a feeding rate of 0.77 g acetonitrile l–1 reactor day–1, 99% of the acetonitrile was removed; and 86% of the nitrogen
The angle dependence of the scattered light from pairs and one-dimensional arrays of nanowires was studied. The intensity of the scattered light varied distinctly during rotation of the structure. The results could be theoretically modeled by treating a pair of nanowires as a double slit and an array of nanowires as a grating. The correspondence between theory and experimental results conclusively
