Popular Abstract in Swedish I detta arbeta har reaktionerna 16O(γ,p)15N och 18O(γ,p)17N studerats med hjälp av reella fotoner. Fotonerna med vilka syrekärnorna har bestrålats har varit i energiområdet 50 - 70 MeV. De utgående laddade partiklarna såsom protoner, deuteroner och tritoner har detekterats med hjälp av två ΔE-ΔE-E teleskop placerade i 70o respektive 110o relativt fotonstrålen. De två 0.A measurement of the reactions 16O(γ,p)15N and 18O(γ,p)17N have been made with tagged photons in the energy range Eγ ≈ 50 – 70 MeV. The protons have been detected in ΔE-E telescopes with silicon strip detectors as ΔE detectors and HPGe crystals as E detectors. Two telescopes have been used with an average angle towards the photon beam of 70 and 110 degrees. The silicon strip detectors have been us

Speaker age is a speaker characteristic which is always present in speech. Previous studies have found numerous acoustic features which correlate with speaker age. However, few attempts have been made to establish their relative importance. This study automatically extracted 161 acoustic features from six words produced by 527 speakers of both genders, and used normalised means to directly compare

Popular Abstract in Swedish Denna avhandling riktar fokus mot en paradox: statsmaktens kontroll och social frihet över Internet ökar parallellt i Kina. Studien, som baseras på fältarbete utfört mellan 2002 och 2006 och 48 intervjuer, söker finna svaren på två frågor: 1. Hur kan internetanvändningen bidra till ett öppnande av den publika sfären, på ett sätt som gör den mer oberoende av enpartistateThe aim of this dissertation is to address a paradox: government control and social freedom on China's Internet are growing simultaneously. The study, which is based on fieldwork conducted between 2002 and 2006, and 48 interviews, seeks answers to the following two questions: 1. How can Internet use contribute to an unlocking of the public sphere, making it more independent from party-state contro

Popular Abstract in Swedish Blommor använder färg och doft för att locka till sig pollinatörer. Hur använder sig svärmare av dessa olika signaler för att hitta blomman? För att få svar på denna fråga undersöktes två arter av svärmare, en dagaktiv, Macroglossum stellatarum, och en nattaktiv, Deilephila elpenor. Båda arterna har färgseende och den nattaktiva svärmaren kan skilja på olika färger äveFlowers use different cues to attract pollinators including colour and odour. How do hawkmoths use these cues to find the flowers? This question was investigated in two species of hawkmoth, the diurnal species, Macroglossum stellatarum, and the nocturnal species, Deilephila elpenor. Both species have colour vision and D. elpenor can discriminate colours under very dim light intensities. Both speci

The combination of solar heat and ground-source heat pumps in dwellings gives opportunities for optimising the use of renewable energy sources and minimize the share of bought energy. Solar collectors in the system may give advantages for the operational conditions both for the solar collectors and for the heat pump. The aim of this project was to analyse different variables such as energy demand,

Popular Abstract in Swedish Ett beta-fosfoglukomutas i kolhydrat-metabolismen hos Lactococcus lactisPhosphoglucomutase (PGM) catalyzes the reversible conversion of glucose 1-phosphate to glucose 6-phosphate. Two distinct forms of PGM have been purifed and charactierized in Lactococcus lactis growing on maltose: one specific for the alpha-isomer, and the other specific for the beta-isomer of glucose 1-phosphate. Beta-PGM was purified and polyclonal antisera to the enzyme were generated. Beta-PGM

Lundaprofessorn Sven Nilsson blev under 1800-talet internationellt känd inom så skilda ämnen som geologi, zoologi och arkeologi. Denna kontrasternas man, beskrivs som brilliant men temperamentsfull och snarstucken, med stort självhävdelsebehov, en svaghet för det sensationella men samtidigt mycket känslig för kritik. Hans faunahistoriska forskning var banbrytande och många av resultaten är aktuell

The book is a Finnish version of Terror och tystnad (2005).

In 2006, a prohibition on less favourable treatment of workers related to parental leave was introduced in The Swedish Act on Parental Leave. The prohibition was designed on the basis of the rules on discrimination of pregnant workers and workers on maternity leave in the Equal Treatment directive. The Swedish rules do however separate from the EU rules in one crucial respect. While the European U

This project, aimed to the digital documentation of archaeological sites, artifacts and cultural relics of the Western Han Dynasty, started in 2008. The anticipated outcome will be the creation of a virtual museum, based on collaborative environments, dedicated to the Western Han Dynasty and able to integrate new archaeological datasets coming from fieldwork activities (most part of them unpublish

The throughput of three slot allocation schemes for the downlink of a wireless TDMA system are investigated under the assumption of block-Rayleigh fading. The schemes use the instantaneous SNR at the users in order to take advantage of the independent fading of the channels. In the first scheme, which has been proposed earlier (R. Knopp et al., 1995), the base station transmits to the user that ex
