This thesis comprises three different topics within the field of tribology. First, design functions for analyses of slider bearings are developed. Second, a lubricant model applied to elastohydrodynamically lubricated (EHL) line contacts considering wall-slip is presented. Finally, an experimental apparatus for investigations of lubricants at high pressures is presented. The design of hydrodynami
Context. Wide hot subdwarf B (sdB) binaries with main-sequence companions are outcomes of stable mass transfer from evolved red giants. The orbits of these binaries show a strong correlation between their orbital periods and mass ratios. The origins of this correlation have, so far, been lacking a conclusive explanation. Aims. We aim to find a binary evolution model which can explain the observed
Aims. The Landé g-factor is an important parameter in astrophysical spectropolarimetry, used to characterize the response of a line to a given value of the magnetic field. The purpose of this paper is to present accurate Landé g-factors for states in B II, C I-IV, Al I-II, Si I-IV, P II, S II, Cl III, Ar IV, Ca I, Ti II, Zr III, and Sn II. Methods. The multiconfiguration Dirac-Hartree-Fock and rel
Introduction: The Assessment of Learning Powered mobility use (ALP) tool including the ALP instrument and facilitating strategies, was developed for Driving to Learn. This therapeutic intervention aims to provide children and adults who have profound cognitive disabilities with opportunities to learn tool use through powered mobility practise. To allow for longer intervention periods, a partnershi
IntroductionPaper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention (PCI). Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. We therefore conducted the SOCCER study to evaluate the effects of O2 therapy in STEMI patients.MethodsPaper I: 560 am
Work environment issues are often divided into the physical work environment, including safety, and the psychosocial work environment. The physical work environment is easier to regulate and monitor. You need to be trained to handle chemicals in a laboratory, we have regular safety rounds and if something happens (like at the nano lab recently), there are routines and procedures in place to limit
Working with sustainability Name: Katarina Crafoord Education: Bachelor's degree in Physical Geography and Ecosystem Science from Lund University. Master's degree in Applied Climate Strategy at Lund University. When you started thinking about university studies, what were you interested in and thought you would work on after graduation? I have always been interested in the environment and sustaina

This thesis concerns assessment of acoustic comfort in apartment buildings. A new approach is followed, beyond noise annoyance investigation, which was the typical path so far. The latter involved acoustic descriptors, which characterize the structural components, being associated to self-reported noise annoyance.A socio-acoustic survey was conducted in 34 Swedish and Danish structures including 1
OBJECTIVES: To describe the long-term perspective regarding prevalence of risk factors, secondary stroke prevention, and lifestyle indices after stroke.METHODS: From a population-based one-year cohort (n = 416), we performed an observational study of 145 survivors at 16 months and 10 years after stroke (age 27-97 years) regarding secondary prevention including reaching acceptable treatment goals;
The rights of women living in societies ruled by laws based on Shari'a constitute a controversial question in the human rights debate in many countries today. Suggestions that these laws are of a divine nature, and as such cannot be overridden by the human rights principles of western origin leads to discussions in several areas, such as the right to religion, the human rights tradition in Mus
Discussion The trend on the mobile phone market indicates that mobiles with advanced texture will be in demand. Sony Ericsson Mobile Communications AB would like to examine what possibilities there are in the field for texturing. In 2006 they introduced the mobile phone W850i with advanced texture on the market and now they want to know more about different techniques for texturing in the future.
The dendritic cell (DC) lineage encompasses a diverse population of cells with unique subtype-specific functions. In peripheral blood, four DC subsets have been identified based on their distinct expression of CD1c, CD141, CD16, and CD123, and these subpopulations exhibit functional properties in immune responses. However, their respective roles in allergic diseases, such as rhinitis, are unclear.
After electrophoresis of an alkaline extract of type 15 group A streptococci, three main precipitation lines were obtained in diffusion experiments against commercial human polyclonal IgG (lines 1, 2 and 3). Nineteen of 23 sera (83%) from apparently healthy human individuals gave line 3, while 6 of them (26%) gave line 1. The sera giving line 1 did also give line 3. Line 2 was obtained with 2 sera
