I nöjesparkens åkattraktioner är det din egen kropp som upplever krafterna i Newtons lagar, när den accelereras i 1, 2 och 3 dimensioner. Du får uppleva det fria fallets tyngdlöshet - eller känna dig mycket tyngre än vanligt när berg- och dalbanan går igenom en dal. Åkattraktinerna ger mpnga fina exempel på krafter i idealiserade situationer, som till exempel Slänggungan/Kättingflygaren på Liseber
This thesis presents two sources of extreme ultraviolet (XUV) radiation based on high-order harmonic generation (HHG) in gases. The sources were developed for experiments requiring high-flux harmonic beams or HHG pulses at high-repetition rate. These were used experimentally to image nano-scale objects. The high-flux HHG source was used for digital in-line holography, and the high-repetition rate
Huntington's disease (HD) is an inherited neurodegenerative disorder characterized by both neurological and systemic abnormalities. We examined the peripheral immune system and found widespread evidence of innate immune activation detectable in plasma throughout the course of HD. Interleukin 6 levels were increased in HD gene carriers with a mean of 16 years before the predicted onset of clinical
Not only the argument from contingency for the existence of God but also the theistic idea that God is the metaphysical foundation of the world seem to presuppose the intelligibility and validity of the following question: Why is there anything contingent at all? However, it has been argued that, upon closer inspection, this question is a pseudo-question: a question which presupposes illegitimate
Scand J Caring Sci; 2010 Case managers for frail older people; a randomised controlled pilot study Aim: The aim was to test sampling and explore sample characteristics in a pilot study using a case management intervention for older people with functional dependency and repeated contact with the healthcare services as well as to investigate the effects of the intervention on perceived health and de
A novel technique for the noninvasive measurement of tissue optical properties simultaneously at all visible and near-infrared wavelengths is presented. The technique is based on.the time-resolved detection of multicolor diffusely scattered light. Short pulses of white light are/produced by using self-phase modulation by focusing the light from a short-pulsed high-power laser into a cuvette filled
This study explores how French adults and children aged four and six years talk and gesture about voluntary motion, examining (1) how they encode path and manner in speech, (2) how they encode this information in accompanying gestures; and (3) whether gestures are co-expressive with speech or express other information. When path and manner are equally relevant, children’s and adults’ speech and ge
Cancer of unknown primary site (CUP) is a fatal cancer diagnosed through metastases at various organs. Little is known about germline genetics of CUP which appears worth of a search in view of reported familial associations in CUP. In the present study, samples from CUP patients were identified from 2 Swedish biobanks and a German clinical trial, totaling 578 CUP patients and 7628 regionally match
Drugs acting on the central nervous system (CNS) and given to a pregnant woman during the latter part of pregnancy may affect neonatal morbidity of the infant. Little is known on the combined effects of different categories of such drugs. The redeeming of prescriptions for CNS-active drugs during the second or third trimester of pregnancy was studied by linkage between a register of prescribed dru
