Popular Abstract in Swedish Allt levande består till stor del av proteiner. De bygger upp muskler och hår, transporterar syre i blodet och ser till att kemin i kroppen fungerar som den ska. Men hur tillverkas då dessa proteiner? Jo i alla celler finns ribosomer, proteinfabriker. En bakterieribosom är ungefär 0.02 mikrometer stor. Den är sammansatt av proteiner och RNA-kedjor. RNA utgör den funktioTranslation is a central biological process, that is catalysed by a machinery consisting of RNA and protein. In this thesis three different protein components of the bacterial protein synthesis system have been structurally studied. Ribosome recycling factor (RRF) is essential for the recycling step of the translation cycle, elongation factor SelB is a specialised elongation factor needed for co-t

Popular Abstract in Swedish Kultursemiotiken studerar möten mellan kulturer. Begreppen Kultur, Extra-kultur och Icke-kultur utvecklades av Tartuskolan under 1970-talet, och användes i deras studier av den ryska kulturen och dess relation till Västeuropa. Särskild vikt lades vid Peter den Stores försök att göra Ryssland mer likt Väst. Målet med denna avhandling i kultursemiotik är att vidareutvecklCultural semiotics studies encounters between cultures. Notions such as Culture, Extra-culture and Non-culture were developed in the 1970s by the Tartu school and were used in their studies of Russian culture and its relation to Western Europe, with special focus on Peter the Great's attempt to Westernize Russia in the eighteenth century. The aim of this dissertation in cultural semiotics is to fu

Competition is an integrated part of most civilizations, from sports to education. Often competition arise whether or not it was intended and higher education is no exception from this. Should teachers acknowledge this and try to introduce competition as a part of the course or should they try to prevent competition, even spontaneously arisen competition? In this paper an overview of effects of co

I denna artikel visas hur Laurentiistiftelsen i Lund som studenthem och gudstjänstgemenskap vuxit fram ur och verkat inom och i relation till Svenska kyrkan. Dess historia speglas i Svenska kyrkans. Stiftelsen varit ett tecken (på Kristi närvaro, på tro och på den icke-territoriella gemenskapens möjlighet), ett löfte (om en framtid och ett hopp, om nåd och förlåtelse) och en gåva (till studenterna

The in vitro formed adducts between hexahydrophthalic anhydride (HHPA) and cysteine and lysine were monitored by mass spectrometry. Freshly synthesized N-acetyl-S-hexahydrophthaloyl-L-cysteine was dissolved in dry acetonitrile and added to a solution of N-acetyl-L-lysine in 0.1 M sodium phosphate buffer (pH 7.4) an incubated at 37°C. The reactions were monitored by LC/MS on a triple quadrupole mas

Popular Abstract in Swedish Fåglars flygförmåga I alla tider har vi fascinerats av fåglars förmåga att flyga, och många försök att förstå och efterlikna dem har gjorts. Kanske den förste som på allvar intresserade sig för mekanismerna bakom fåglars flykt var Leonardo da Vinci som runt år 1500 funderade på hur fåglar alstrar lyftkraft. Leonardo skissade också på 100-tals maskiner som var tänkta atI share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. Gliding flight performance of a jackdaw was measured in a wind tunnel and I conclude that the current model for predicting optimum wingspan as a function of forward gliding

Med finansiering från Naturvårdsverket har forskare från IVL, SMHI, Göteborgs Universitet samt SLU genomfört en analys av de ekonomiska värdena av den negativa inverkan av marknära ozon på växtligheten i Sverige vid olika scenarier för ozonbelastning och i relation till föreslagna målvärden vad gäller preciseringen för ozon och växtlighet inom miljömålet Frisk Luft. Arbetet utgör i stor utsträckni

Solid oxide fuel cells (SOFCs) have the attractive feature to be able to make use of hydrocarbon fuels in their operation by reforming the fuel into pure hydrogen, either internally or externally. This can open up for a smoother transition from the existing hydro-carbon economy toward a more renewable hydrogen economy. Since both SOFCs and internal combustion (IC) engines can make use of hydrocarb

In this paper, we discuss the internet low bit rate codec (iLBC) with an emphesis on the frame-independent longterm prediction. The frame-independent long-term prediction is a method to exploit pitch-lag correlations in the encoding of speech without suffering multiple-frame speech degradation in connection with transmission loss. We present mean opinion scores for the iLBC codec and show by means

The subject who understood. The Swedish Reformation discourse and the early modern process of integration The thesis concerns why it in the discourse of the Reformation was so important to repeat statements about the need for Christendom to go back to its true heritage and that the sermon should be understood by everyone, and the statements consequences for the possibility of formulating order, co

In the research on two of the most prominent persons among those who rescued Jews from the Holocaust, Oskar Schindler and Raoul Wallenberg, a reappearing purpose has been to separate mythical, and therefore more or less false, elements in the story from the true, and implicit, academic historical writing. However, during the last decades, it has been obvious that history is not only, and sometimes
