High-resolution spectroscopy measurements have been performed using near-infrared diode lasers. Special emphasis was placed upon high accuracy absorption lineshape measurements, which provide the basis for quantitative gas analysis. For this purpose, relevant spectral characteristics of the radiation emitted by diode lasers were studied. High-resolution measurements using newly developed long-wave
The aim of this work was to determine the extent to which soot is formed and if there are any ways of reducing the formation of soot. In order to determine if soot formation will be a critical issue for the reverse flow reforming process modeling of the process was undertaken. The reformer was modeled using a detailed reaction mechanism to describe the kinetics of soot formation.The results of the
Decentralised and scalable conditions for robust stability of networks of heterogenous linear time-invariant (LTI) systems are derived based on integral quadratic constraints. These generalise previous works in the literature with an increased flexibility in the choice of multipliers employed. The results allow for arbitrary interconnection matrices and accommodate multi-input-multi-output systems
Twin and family studies have established that there is a strong genetic basis for autism spectrum disorders. To facilitate the identification of susceptibility genes and to study pathways from gene-brain to cognition a more refined endophenotype-based approach may be useful. The purpose of the present study was to examine the neurocognitive endophenotype of autism, in families with multiple incide
The new injector for MAX-lab is built around two 125 MeV linacs [B. Anderberg, (2000)] equipped with SLED cavities [Z.D. Farkas, (1974)]. The electron beam is recirculated once to reach 500 MeV. A 2.3 MeV thermionic RF gun [B. Anderberg, (2000)] injects into the system. The RF-gun is put into operation and commissioning of the first linac is proceeding. Results from the thermionic RF-gun operation

Popular Abstract in Swedish GENETISK VARIATION OCH SEXUELL REPRODUKTION I EN MOSSA MED DVÄRGHANNAR, KALKLOCKMOSSA Mycket små hannar (dvs. dvärghannar) finns i flera olika djurgrupper men inom landväxterna bara hos mossor. Hos mossor uppstår dvärghannarna ifrån hansporer som landar och gror på honskottet där de inte blir större än några millimeter. Sporerna bildas inuti sporkapseln, som växer ut ifDwarf males occur in many unrelated groups of organisms. Among land plants they are unique to mosses. Moss dwarf males originate from male spores that land and germinate on the female where their final size is restricted to a few mm. Fertilization in mosses occur over short distances with swimming spermatozoids. Having the males growing as tiny epiphytes on the females facilitates fertilization, a
Breast reconstruction is an everyday, apparently non-violent, even benevolent, remaking of the normal and the reasons for why reconstruction is motivated and legitimate are uncontroversial and widely accepted. In this article I will, through Donna Haraway’s way of conceptualizing discourses, analyze what I call “stories without significance”. I have mapped the stories and interpretations women und
Popular Abstract in Swedish Svängningar i antalet individer hos en organismgrupp har under lång tid intresserat forskningen. Men sådana fluktuationer i populationer har inte bara ett vetenskapligt intresse. En ökad förståelse för fenomen som dessa kan hjälpa oss att fatta bättre beslut rörande mänskliga aktiviteter såsom fiske, jakt, skogsbruk och jordbruk och förhoppningsvis leda oss mot ett mer We are interested in the effect of harvesting on population fluctuations and for that purpose we develop and analyze an age-structured model where recruitment is a stochastic process and the adult segment of the population is harvested. When a constant annual harvest is taken the coefficient of variation of the adult population increases for most parameter values due to the age truncation effect,
