Ultrafast accelerator-based sources combined with synchronized femtosecond lasers are currently being developed. The method described here is intended as a jitter monitor at such facilities. We report on the possibility of extracting a time-offset signal between two different synchronized ultrashort light pulses. The method is based on sum-frequency generation in a nonlinear crystal. Aiming at ext
Three experiments were conducted to investigate the impact of affect on moral judgment. Participants read stories describing morally questionable actions and made judgments of wrongness. Judgments were affected by morally irrelevant disgust, and the effect was moderated by individual differences in disgust sensitivity and preferred processing mode. More specifically, the effect was stronger for pa
An extensive research program, dealing with fire growth on combustible wall lining materials, has been ongoing in Sweden over the last decade. Several lining materials were tested in bench-scale fire tests in order to derive basic material flammability parameters. The same materials were also tested in a full scale room test and a 1/3 scale room test for two different scenarios, A and B. Scenario
Popular Abstract in Swedish I de hänvisningar som används i ett stort antal sociala projekt för att målet skall uppnås hittas rättighet och rättvisa som centrala diskursiva enheter i en återkommande använd tankemodell. I flera av dessa projekt blir resultatet, gång efter annan, utebliven framgång. Men den samma rätta tankemodellen förblir en självklar utgångspunkt. De upprepade krigen mot fattigdoIn the references invoked by a large number of social projects to achieve their goals, one can find rights and justice as central discursive units in a frequently recurring thought model. In several of these projects the result, time after time, is lack of success. But the same right thought model continues to be taken for granted as a point of departure. The repeated wars on poverty in the USA ex
The objective was to investigate the relation between serum levels of interferon-alpha (IFN-alpha), the activity of an endogenous IFN-alpha inducing factor (SLE-IIF), clinical and immunological disease activity as well as serum levels of antiretroviral antibodies in SLE. Serum levels of IFN-alpha were measured in serial sera from 30 patients sampled at different stages of disease activity (SLEDAI
Background: Laser photocoagulation is a well-established treatment for diabetic retinopathy but the mechanism behind its effectiveness has not been elucidated. The protein kinase C (PKC) family is a group of enzymes which has been the subject of extensive interest in clinically related research since the advent of its role in the pathogenesis of diabetic retinopathy. With this study we wanted to e
The electrostatic properties of charged surfactant micelles are investigated through titrations of fatty acid probes solubilized in the micelles. The titration process is followed by means of calorimetric measurements and by determining the pH values as a function of added base. This approach yields a complete thermodynamic description of the titration process. In particular, we find that the proc
Popular Abstract in Swedish Avhandlingen består av fem fristående uppsatser som utnyttjar tidsserieanalys för studerande av några olika makroekonomiska frågor. I kapitel två, tre och fyra används s.k. vektorautoregressiva (VAR) modeller för att studera privat konsumtionsbeteende i Sverige. Enligt den permanenta inkomst hypotesen väljer individerna sin konsumtion med hänsyn till sin långsiktiga ellAdvances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate. Chapter two explores the empirical evi
Estimating catchment scale soil loss based on rainfall simulators is often hampered by the difficulty to scale up simulator results. Our objective was to develop and test a method for estimating catchment scale soil loss based on observed rainfall using a variable intensity rainfall simulator in an erosion-sensitive catchment in semiarid Tunisia. A 7-year period, 1992-1999, with observed sedimenta
The ability to identify methicillin-resistant staphylococci by the disc diffusion method was evaluated using discs containing oxacillin (1, 5 and 10 micrograms), methicillin (10 micrograms) and cephalexin (30 micrograms). Strains of Staphylococcus aureus (67 strains) and coagulase-negative staphylococci (72 novobiocin-sensitive and 27 novobiocin-resistant strains) were studied using two inoculum d
Abstract in French Cette étude a été réalisée pour déterminer si les papillomatoses virales du col sont associées à l'utilisation des contraceptifs et aux antécédents de reproduction. Après avoir enregistré les antécédents de contraception et de reproduction de 972 femmes ayant demandé des conseils en matière de contraception, des examens ont été conduits pour dépister toute infection de papillomaThe study was conducted to investigate whether cervical human papillomavirus infections (CHPI) are associated with contraceptive use and reproductive history. The contraceptive and reproductive histories in 972 women seeking contraceptive advice were noted and screening conducted for human papillomavirus infection. The interview included number of pregnancies and childbirths, legal and spontaneous
Complexes of oppositely charged polymers and surfactants (OCPS) in water come in many varieties, including liquid-crystalline materials, soluble complexes, structured nanoparticles, and water-insoluble surface layers. The range of available structures and properties increases even further with the addition of other amphiphilic substances that may enter, or even dissolve, the complexes, depending o
In many organisations a gap exists between IT management and emergency managemement. This paper illustrates how process improvement based on a maturity model can be used to help organisations to evaluate and improve the way they include IT dependability information in their emergency management. This paper presents the IDEM3 (IT Dependability in Emergency Management Maturity Model) process improve
The key step in the reaction mechanism of multicopper oxidases (MCOs)-the cleavage of the O-O bond in O-2-has been investigated using combined quantum mechanical and molecular mechanical (QM/MM) methods. This process represents a reaction pathway from the peroxy intermediate after it accepts one electron from the nearby type-1 Cu site to the experimentally-observed native intermediate, which is th
Background: One key aspect of person-centredness is striving to understand both the patients' experiences and behaviours from their perspective. These aspects are precisely those that staff in dementia care highlight as causing them most difficulty because the people in their care have major problems expressing themselves. There is thus a need to develop a method to help the staff to achieve inter
Popular Abstract in Swedish Senare års forskning har klart och entydigt pekat på njurens viktiga roll i utvecklingen av högt blodtryck. Det är mycket sannolikt att det föreligger flera av varandra oberoende mekanismer som förklarar uppkomsten av högt blodtryck, men det är möjligt att flera av dessa, på en organfysiologisk, cellfysiologisk eller genetisk nivå kan ha gemensamma patofysiologiska länkStudies were conducted to investigate the role of macula densa (MD)-derived nitric oxide (NO) in regulation of the glomerular filtration (GFR) through the tubuloglomerular feedback (TGF) mechanism. Immunocytochemical localization of the neuronal isoform of NO synthase (NOS) in the kidney showed that this isoform was exclusively located in MD cells. Whole kidney clearance measurements of GFR and mi

Subjects and setting: Thirteen healthy subjects volunteered for the first study, and 14 for the second. The tests were performed at Applied Nutrition and Food Chemistry, Lund University, Sweden. Experimental design and te
Popular Abstract in Swedish Olika rapporter har fastslagit att de traditionella svenska folkrörelserna (såsom arbetarrörelsen och frikyrkorörelsen) tappar medlemmar. Istället för att ansluta sig till ett politiskt parti eller en kyrka söker sig politiskt eller religiöst intresserade individer till nya, individualiserade, former av engagemang. Denna avhandling studerar en grupp män och kvinnor somVarious reports have stated that the traditional Swedish popular movements (e.g. the Workers movement and the Free church movement) are loosing ground. Instead of joining a political party or a church, politically or religiously active individuals are said to seek out new and individualized ways of being involved. This thesis studies a number of men and women that persist in being communally invo
In today’s society people are overwhelmed with information about different kinds of heating systems. The purpose of this study is to examine the factors that impact households when they make decisions on heating systems, and also how households value different types of information on the subject. Four Swedish municipalities were chosen for closer examination. Municipal energy advisors and represe
