Emission spectroscopy has been utilized to provide information about the electron density and temperature in streamers and breakdown arcs in transformer oil. Recorded spectra include strongly broadened hydrogen Balmer-alpha lines and vibration/rotation band profiles of the C-2 molecule. The origin of the observed broadening of hydrogen lines is discussed and it is concluded that it arises mainly f
Monitoring of free gas embedded in scattering media, such as wood, fruits, and synthetic materials, is demonstrated by use of diode laser spectroscopy combined with sensitive modulation techniques. Gas detection is made possible by the contrast of the narrow absorptive feature of the free-gas molecules with the slow wavelength dependence of the absorption and scattering cross sections in solids an
Nyligen har mycket uppmärksamhet ägnats åt studier rörande ickelinjära oscillationer av sfäriska gasbubblor i pulserande tryckfält. Denna lic-avhandlning syftar till att utöka kunskapen kring kavitationsfenomenet. I detta arbete undersöks olika modeller och en förbättrad numerisk modell har utvecklats för att analysera akustiska kavitationsfenomen. Resultaten från den utvecklade modellen innefatta
Abstract The present study is part of a larger project investigating occupational engagement and health in a group of people with schizophrenia. This study was aimed at extending this knowledge base with regard to occupational engagement and sociodemographic factors. Seventy-four outpatients participated in the study. The Profile of Occupational Engagement in People with Schizophrenia, the Lancash
Essay/Understreckare about carnivorism and Melanie Joys new book Varför vi älskar hundar, äter grisar och klär oss i kor.
This study focuses on the embedding of new biotech solutions into three business landscapes - US, China and Taiwan. A "state-of-the-art" chromatography system tuned for operating in the step between laboratory and large-scale production is used as the common point of departure to investigate the supplier-user interfaces involving biotechnology in each of the three countries; the resource interacti
Popular Abstract in Swedish Avhandlingen består av tre separata papper. De är alla empiriska studier som undersöker hur fragmentering av produktionsprocesser och globala utbudskedjor har påverkat internationell handel. Den första studien fokuserar på hur privata standarder i den alltmer globaliserade livsmedelsindustrin påverkar företags importbeteende. Genom att ge en kvalitetsförsäkran kan certThis thesis consists of three separate papers. They are all empirical papers that examine how fragmentation of production processes and global value chains have affected international trade patterns. The first paper focuses on how private standards in the increasingly geographically fragmented food sector affect firm-import behaviour. By providing a quality insurance for the imported good, certif
The presence of various mechanisms of non-genetic inheritance is one of the main problems for current evolutionary theory according to several critics. Sufficient empirical and conceptual reasons exist to take this claim seriously, but there is little consensus on the implications of multiple inheritance systems for evolutionary processes. Here we use the Price Equation as a starting point for a d
When God moves out - deserted churches in the past and the present: A discussion on the fate and future of deserted churches since the Middle Ages in mainly Scandinavia. The article is departuring from the case of Maglarp in Scania, where a church from 1909 was demolished in 2007.
A self-similar, continuous process with stationary increments is considered as an approximation to the surplus process in collective risk theory. This approximation can be seen as the weak limit of risk processes with linear premium income, where the claim sizes show a long-range dependence. It is then proved that the corresponding ruin times converge weakly to the ruin time of the approximation p
AIMS: The sural nerve is the commonest peripheral nerve biopsied to help in the diagnosis of peripheral neuropathy of unknown cause. However, associated complications limit its use. The aim was, as an alternative, to asses biopsy of the terminal branch of the posterior interosseous nerve (PIN) in the forearm. METHODS: PIN pathology was morphometrically quantified in 10 male patients with Type 2 di
Introduction to the films of Swedish artist and filmmaker Claes Söderquist (b. 1937)
In order to investigate the association between leisure time physical activity in the year before pregnancy and pre-eclampsia, stratifying for maternal BMI, a prospective study was carried out from 1996 to 1998. Pregnant women attending their first antenatal care visit, were invited to participate in the study. Inclusion criteria: Danish-speaking, > OR =18 years of age, gestational age <22 weeks,
This paper introduces a novel transmission technique for MIMO broadcasting directional channels, herein called the Angle-of-Departure-Aided Opportunistic Space-Division Multiple Access (AOD-OSDMA) technique. In AOD-OSDMA, the knowledge of angles-of-departure (AODs) at the BS of the strongest signal received by each user is used to design multiple opportunistic beams so that advantage is made of th
