Four juvenile Ross's gulls Rhodostethia rosea were trapped on the New Siberian Islands in the Laptev Sea in early August 1994, allowing data collection on body mass and morphometrics from a poorly known part of the species' annual cycle. The wings of juvenile birds were shorter than those previously reported for adults, but their bill length and tarsus length were similar. Their average body mass
Popular Abstract in Swedish Arkitekten Hans Westman var verksam i Skåne från 1932 till 1983. Hans rika och mångskiftande produktion har satt sin prägel på den moderna skånska arkitekturen, särskilt i Lund där han hade sitt arkitektkontor. Westmans arkitektur spänner över ett brett fält från bostadshus, offentliga byggnader, kraftverk till kyrkor och kloster. Flera verk är välkända, t ex radhusområThis thesis deals with the regional aspects of Swedish modernism exemplified by the architecture of Hans Westman (1905-1991). The main purpose of the dissertation has been to make a survey of what is perceived as particularly regional in Westman's buildings and if we can really talk about modern regional architecture. Modernism's breakthrough brought about the introduction of an architecture which
Popular Abstract in Swedish Syftet med studien har varit att, genom huvudsakligen kvalitativ beskrivning, studera narrativ sekvens, d v s berättelsen, i exolingvala samtal mellan infödd och icke infödd (svensktalande studenter) talare av franska. Den teoretiska ramen sträcker sig från textlingvistik (Revaz, Adam, Bronckart etc.) till konversationsanalys (Labov, Sacks, Norrick, Laforest, Kerbrat-OrThe aim of this study is to examine, through a mainly qualitative description, the narrative in exolingual conversations in French between non-native speakers (NNS) (Swedish students) and native speakers (NS). The theoretical frame ranges from text linguistics (Revaz, Adam, Bronckart etc.) to conversation analysis (Labov, Sacks, Norrick, Laforest, Kerbrat-Orecchioni, Bres, Norrby etc.). The study
Popular Abstract in Swedish Bakgrund - Glutenintolerans (celiaki) är en vanlig kronisk tunntarmssjukdom som drabbar 1% av befolkningen och beror på att man inte tål ämnet gluten som förekommer i vete, korn och råg. Celiaki är delvis ärftligt och förekommer i alla åldrar, men upptäcks framför allt hos barn. Intoleransen mot gluten orsakas av en immunologisk reaktion mot tunntarmens slemhinna som efCeliac disease is a prevalent small bowel disease in children caused by permanent intolerance against gliadin, which is the alcohol-soluble fraction of the cereal protein gluten in wheat, rye and barley. Celiac disease is characterized by an inflammatory infiltrate of CD4+ T lymphocytes in the intestinal mucosa leading to damage of villous structure and loss of absorptive surface. As a consequence
Empirical evaluations in software engineering are important in order to build a body of knowledge of methods that work in different environments. This thesis presents six empirical investigations of two techniques applied to software inspections, namely reading techniques and fault content estimation techniques. The first part of the thesis presents a series of experiments of a novel reading tech
Theories of democracy consider communicative interaction among citizens central, In recent years the idea of deliberative democracy has galvanised elements of political theory with perspectives on communication. This concept emerges to a large extent from the Habermasian trajectory and links currents from theories of civil society and citizenship. It has thus a rather forceful normative dimension.
This paper treats estimation of the Wigner-Ville spectrum (WVS) of Gaussian continuous-time stochastic processes using Cohen's class of time-frequency representations of random signals. We study the minimum mean square error estimation kernel for locally stationary processes in Silverman's sense, and two modifications where we first allow chirp multiplication and then allow nonnegative linear comb
The discrete-time 'analytic' signal finds numerous applications in a wide range of fields, and call be efficiently implemented using the fast Fourier transform (FFT). A computationally efficient sliding window time-update of the discrete-time 'analytic' signal, not requiring the FFT, is proposed.
There is a need for objective and quantitative methods for measuring posture and movement, so that, for instance, exposure-response relationships for work-related musculoskeletal disorders can be established. Inclinometry data have been obtained from triaxial accelerometers based on uniaxial solid-state accelerometers used in conjunction with a computer program to perform co-ordinate transformatio
The proper handling of alarms is crucial to any automated process control. In practice, many alarms are only distractive and do not represent a potentially dangerous situation. This paper presents a methodology and a computerized tool that aims to remove such nuisance alarms, a so-called alarm cleanup. This is a general, systematic approach that takes advantage of the control system's built-in fun
Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. Formation of acetate occurs under anaerobic cond
In prediction (Wiener-, Kalman-) of a random normal process $\{X(t), t \in R\}$ it is normally required that the time $t_0$ from which prediction is made does not depend on the values of the process. If prediction is made only from time points at which the process takes a certain value $u,$ given a priori, ("prediction under panic"), the Wiener-prediction is not necessarily optimal; optimal should
Self-organization in aqueous systems based on ionic surfactants, and their mixtures, can be broadly understood by a balance between the packing properties of the surfactants and double-layer electrostatic interactions. While the equilibrium properties of micellar systems have been extensively studied and are understood, those of bilayer systems are less well characterized. Double-chained and pseud
