High-resolution core-level photoemission spectroscopy and temperature-programmed reaction experiments together with density functional theory calculations were used to elucidate on the atomic scale the chlorination mechanism of ruthenium dioxide RuO2(110) by hydrogen chloride exposure. The surface-selective chlorination accounts for the extraordinary stability of the RuO2 catalyst in the Sumitomo
Soot particles strongly absorb radiation in the visible and infrared spectral regions, and the soot interaction with laser light during laser diagnostic interrogation leads to particle heating and often to subsequent sublimation. Consequently, laser-heated particles transfer heat to the ambient gas leading to local gas heating, a process that has received minor attention so far in the diagnostic c
Tungsten particles have been introduced into the National Spherical Torus Experiment (NSTX) in Princeton with the purpose to investigate the effects of tungsten injection on subsequent plasma discharges. An experimental setup for the study of tungsten particle transport is described where the particles are introduced into the tokamak using a modified particle dropper, otherwise used for lithium-po
A number of CCS-technologies are currently being developed for the reduction of CO2 emissions from thermal power stations. One such technology is the oxyfuel process, in which a mixture of CO2 and steam is used as the working medium. The semi-closed oxyfuel combustion combined cycle (SCOC-CC) is an oxyfuel cycle where the working medium mainly consists of CO2 (85-95%). Current practice is to desig
Popular Abstract in Swedish Avhandlingens huvudsyfte är att försöka utreda hur man kommer till förståelse av det historiska huset och att diskutera vilken roll den historiska dokumentationen spelar i restaureringsprojekteringen. I restaurering som i allt annat arbete med arkitektur är förståelse ett nyckelord. Förståelse för de särskilda förutsättningar som ligger i uppgiften, i objektet, i skapanThe principal aim of the thesis is to evaluate the significance of the documentation of a building’s history for the work of restoring it and caring for it. Thus it may be said to address restoration as a hermeneutical problem, besides considering the relationships between the work of documentation; analyses of the resulting data; and the creative process in which the ideology of restoration is im
This paper deals with bandwidth allocation in a Bluetooth scatternet. The proposed assignment of transmission rights provides a controlled traffic transfer between Bluetooth piconets and represents a key component in an ad-hoc wireless Bluetooth network in order to provide with efficient data packet passing within and across piconets. This assignment is obtained by executing a distributed algorith
Gaia is ESA's ambitious space astrometry mission with a foreseen launch date in late 2011. Its main objective is to perform a stellar census of the 1,000 million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec (μas) level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS) - th
Release of glycerol and free fatty acids (FFA) was investigated in human skeletal muscle strips. In the basal state, glycerol and FFA were released at almost equimolar rates (0.3 nmol/ng tissue.90 min). A nonselective beta-adrenoceptor agonist, isoprenaline, caused a concentration-dependent stimulation of glycerol release, whereas FFA release was unaffected. Basal and isoprenaline-induced glycerol
A series of field studies at cold workplaces were initiated. This paper deals with a study at a harbour and the main attention is paid to the thermal responses of the feet and footwear performance. The study was carried out in February. Eight male workers were the subjects. They were selected among volunteers who carried out four different jobs in pairs. The warm winter boots were provided by the
Objectives. To evaluate the incidence of coronary events (CE) and case fatality in relation to common carotid intima-media thickness (IMT) and carotid plaque over a median follow up of 7 years. Subjects. A total of 5163 Swedish middle-aged men and women with no prior myocardial infarction and/or stroke. Methods and results. The associations amongst B-mode ultrasound determined common carotid IMT
We report the weight, stature, body mass index (BMI), and muscular strength of men about 19 years old who have cleft lip, either with or without cleft palate (CLP), or cleft palate only (CP). Data were obtained from the Swedish National Service enrolment register for the years 1991 - 97, and concerned 335 men with CLP and 88 with CP, who were compared with a control group of 272 879 men. The data
Objective. To explore whether infravesical outlet obstruction is associated with alterations in calcium activation of detrusor smooth muscle. Material and methods. Outlet obstruction was created by partial ligature of the urethra in female rats. Western blotting was performed using an antibody against the cytoplasmatic region of the alpha(1c) subunit of the L- type Ca2(+) channel. Intracellular ca
Popular Abstract in Swedish I samband med 1990 års skattereform förändrades den allmänna inkomstskatten i grunden. Bl.a. infördes skilda skatteskalor för arbetsinkomster och kapitalinkomster. Inkomster som genereras av arbete beskattas progressivt med 45-75 % men avkastning av kapital proportionellt med 30 %. Allokering av inkomst till respektive inkomstkategori har därför stor betydelse i skattesSince the tax reform of 1990 the Swedish tax system separates earned income and capital income. On earned income such as "income from business" taxes and fees leads to a total margin tax burden that vary between 45 and 75 %. This margin effect can be compared to the 30 % proportional income tax on capital income. The allocation of income to earned income or capital income is therefore an important
In this paper water and salt mass balances for the Dead Sea were modeled. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production, and brine discharge were included in the models. The mixing time in the Dead Sea was modeled using a single-layer (well-mixed) a two-layer (stratified) system. Using the single-layer approach the water le
Corporate mergers and acquisitions (M&As) have during the last decade established themselves as prominent tools for corporate strategy. Consequently, more and more organizations direct their attention towards the potential benefits of a corporate merger and acquisition (M&A) and the problems of leveraging the potentials. This thesis addresses information systems (IS) integration in the con
This paper presents the first results of analyzing the functions of intonation and word order in Puyuma. Puyuma is an endangered Austronesian language spoken in Taiwan. As other languages of this branch, Puyuma is verb initial and displays variations in word order, so that VOS, SVO and VSO are attested. The aim of our study is to explain these word variations. We investigate the connection between
Popular Abstract in Swedish Den här avhandlingen, vars kontext är staden Jönköping – känd som Smålands Jerusalem – och dess omnejd, vill besvara frågan: Hur utformades och användes berättelsen om missionen i Kina för att åstadkomma och upprätthålla missionsvänskapets hängivenhet? Det var vid skiftet mellan 1880- och 1890-talen, under växande arbetslöshet, bostadsnöd och fattigdom, med konfrontatioThis thesis intends to answer the question: How was the narrative of the mission in China formulated and used to engender and sustain the fervour of the friends of the mission in the 1890s? It was at this time, with growing unemployment, lack of housing, and of poverty – a time when new and challenging ideas emerge – that the interest in the missions to China awoke. The context of the missionary n
Road safety is one of the most important emerging applications envisioned for Vehicular Ad hoc Networks (VANETs). Generally, such applications involve the broadcast of safety messages, consisting of beacons transmitting vehicles' state (e.g. position and velocity) with a regular period, as well as emergency messages warning about unexpected critical events. From the perspective of safety, the appl
