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
The catalytic performance of porous silicon (PS) micro enzyme reactors (muIMER) is strongly dependent on the PS matrix morphology for enzyme immobilisation. PS was achieved in the muIMER by anodisation in a HF-ethanol mixture. PS etching of structured silicon surfaces commonly results in an inhomogeneous pore formation. The deep channel microreactors described herein have previously suffered from
An analysis is presented of the first harmonic radar studies of pheromone-plume locating flights of male Agrotis segetum moths over distances of up to 500m. Upon release most moths flew in a direction having a downwind component. The first significant changes in flight orientations occur in the immediate vicinity of a pheromone source. Moths that were initially flying downwind change course and st
The use of water injection in a homogeneous charge compression ignition (HCCI) engine was experimentally investigated. The purpose of this study was to examine whether it is possible to control the ignition timing and slow down the rate of combustion with the use of water injection. The effects of different water flows, air/fuel ratios and inlet pressures were studied for three different fuels, is
This article deals with the situation in Denmark during the Second World War, reviewing the various revisions which have developed to undercut an entirely heroic reading. The article connects the somewhat ambiguous relationship of Danes to Jews in the interwar period to contemporary issues. In Denmark and elsewhere in Scandinavia, prejudice against Muslims and other immigrant has begun to challeng
The in vitro replication of the Torque teno virus (IT virus) tth8 full-length genome and particle formation in a Hodgkin's lymphoma-derived cell line after transfection with cloned viral DNA were demonstrated. Analyses of the transcription patterns of tth8 and tth7 TT virus isolates in a number of lymphoma and T-cell leukemia cell lines indicated differential additional splicing events and intrage
Bland alla kulturskatter i Lunds universitetsbiblioteks samlingar finns breven till Esaias Tegnér. Många forskarhänder har under årens lopp bläddrat bland de drygt 2700 breven. De har slitit och nött på de sköra pappersarken. För att bevara breven och tillgängliggöra dem för framtida forskare har ett digitaliseringsprojekt startat vid Universitetsbiblioteket. I samband med digitaliseringsarbetet f
Popular Abstract in Swedish Hur kommer det sig att liknande reformprogram återfinns i olika länder? Varför väljs vissa idéer framför andra? Avhandlingen syftar till att öka förståelsen av så kallad policydiffusion, spridning av olika typer av policy, och den dynamik som omgärdar spridningen. Detta görs genom att undersöka hur externa, eller utländska, idéer integreras och översätts i en ny omgivniSimilar policies may be found in different countries. This, in turn, is an indication that policies travel. But why are certain policies imitated while others are not? The author seeks to further our understanding of policy diffusion and its dynamics by investigating how foreign ideas are integrated and translated into new contexts, and how these imported ideas influence national policymaking and
Popular Abstract in Swedish Bankerna har under de senaste decennierna konfronterats med och genomgått stora förändringar. En global ekonomi har vuxit fram och konkurrensen inom banksektorn har hårdnat, vilket bl a har resulterat i mindre räntemarginaler på lån och krediter. En konsekvens av detta är att man har tvingats minska resurserna som spenderas på varje enskild kund, vilket i sin tur har leThe competition in the banking industry has during the last decades been intensified resulting in smaller interest margins. As a consequence, the resources spent on each credit customer have had to be decreased, resulting in less interaction and a perceived limited access to valuable information. This has especially been the case in the banks´credit management of small firms. Earlier research app
Approximately 800 genes coding for seven-transmembrane, G-protein-coupled receptors have so far been recognized. In spite of this, many of these receptors are defined by their sequence only, and are therefore classified as orphan receptors. Without knowing what their endogenous ligands are, we lack the information needed to understand their physiological role and hence cannot make use of them as d
