This paper examines the continuity, change and adaptation of blat – as a Soviet time, informal, economic transaction network, that existed as a response to a non-functional economy. The analysis is based on 33 in-depth interviews conducted in 2009 during a pilot field study in Ukraine and Belarus. The main focus is on individuals’ descriptions, justifications and explanations of their ongoing info
Several serious problems such as material durability and fouling in the High Temperature Heat Exchanger (HTEH) for Externally Fired Micro Gas Turbines (EFMGT) cause the low thermal efficiency. In this study for increasing the thermal efficiency, a duct around a cylindrical fixed bed combustor which burns wood pellets is proposed and two different designs, empty and porous material filled, are inve
A hot potato: food and meals in families with small children and teenagers. Introduction, with aims and hypothesis The project ‘Konsumenters problemlösningar på livsmedelsmarknadens nya arenor. Matinspiration under tidspress’ [‘Consumers’ problem-solving/solution to the food market’s new arenas: food inspiration against the clock’] initially addressed the following issue: shopping for food and p
Savannas are inherently “disturbed” ecosystems, but the regularly recurring disruptions play such a fundamental ecological role (Scholes and Archer, 1997) that “episodic events” rather than “disturbance” may the more apt terminology. From an atmospheric perspective, fire is the most significant of these episodic events. Fires shape community species composition; tree to grass ratio and nutrient re

Popular Abstract in Swedish Informationsteknologin utvecklas i allt snabbare takt. Däremot tycks utvecklingen ske långsammare när det gäller de modeller, metaforer och metoder som används för att beskriva och förstå hur information sprids och hanteras i organisationer, i kommuner och i samhället i stort. Använder vi egentligen IT på ett effektivt sätt i det dagliga arbetet? I den här avhandlingen New information technology is developing faster than the models, metaphors and methods in use for conceptualizing the sharing and managing of information in organizations, in communities and in society in general. The way we utilize information technology today does not seem to succeed in supporting the everyday work practices through which organizations accomplish their work. In this Ph.D. disser
Varför vet alla med svenska som modersmål att det heter "en intressant bok" och inte "en bok intressant"? Det beror på vår fantastiska, inre grammatik. Insikten om hur man uttrycker sig på modersmålet är något som barnet lär sig under de första levnadsåren, och redan i treårsåldern behärskar barnet huvuddelen av de omedvetna regler och principer som styr hur meningarna i modersmålet är uppbyggda.
Popular Abstract in Swedish Tillväxtintentioner och kommunikativ praktik Strategiskt entreprenörskap vid företagsutveckling Denna avhandling fokuserar på entreprenörers “will and skill”, d.v.s. viljan och den kunskap och färdighet som entreprenören har vid start och utveckling av ett företag. Med vilja avses entreprenörens tillväxtintention och med kunskap och färdighet avses kommunikationen mellThis thesis focuses on the “will and skill” of individuals who take part in activities of running a business. The aspect of “will” is studied in terms of growth intentions and the aspect of “skill” is studied in terms of communicative practices. The overall purpose is to explore how entrepreneurs think and talk about growth and how they act in their communicative practices to express their growth
Popular Abstract in Swedish Den första delen av denna avhandling behandlar teoretiska aspekter på stärkelsens kristallina egenskaper. Vår förståelse av dessa egenskaper är baserad på modeller som erhållits via kristallografiska undersökningar av modifierad amylos. Mycket tyder på att dessa modeller är direkt överförbara till amylopektin som utgör den kristallina komponenten i stärkelse. En stor deThe crystalline properties of starch constitutes a puzzling area of research. Our understanding of the crystalline structure of amylopectin, that is the crystalline component in starch, is based on the observations from investigations on modified amylose. The first part of this thesis includes a discussion of the unit cells (the smallest crystalline units) suggested in the literature. The differen
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Målet med denna avhandling var att undersöka hur cancersjukdomar i barndomen och behandlingen av dessa påverkar olika aspekter av fortplantningsförmågan i vuxen ålder. Glädjande nog har andelen patienter som överlever cancer i barndomen de senaste decennierna ökat stadigt till nivåer som idag ligger på nästan 80%. Ökad överlevnad medfChildhood cancer (CC) survival rate has increased over the last couple of decades, today approaching 80%. Therefore more attention has been paid to late effects. One important issue for CC survivors (CCS) is impaired reproductive function. CC per se and/or its treatment can impair the reproductive ability by affecting sperm production, as well as by damaging sperm DNA. This is a matter of concern,
Popular Abstract in Swedish De ökande kraven på högre datahastigheter inom trådlös kommunikation ställer allt högre krav på både radiosändare och mottagare, då dessa behöver utnyttja fler frekvensband med större bandbredd vid högre frekvenser. Fokus i denna avhandling ligger på högfrekvensdelen av radiomottagaren, som består av lågbrusförstärkare, blandare, och oscillatorer vid mikrovågsfrekvenserThe increasing demand for high data rates in wireless communication systems is increasing the requirements on the transceiver front-ends, as they are pushed to utilize more and wider bands at higher frequencies. The work in this thesis is focused on receiver front-ends composed of Low Noise Amplifiers (LNAs), Mixers, and Voltage Controlled Oscillators (VCOs) operating at microwave frequencies. Tra
Fifty years after the foundation of the Combustion Institute and almost 150 years after Michael Faraday's famous lectures on the combustion of a candle, combustion diagnostics have come a long way from visual inspection of a flame to detailed analysis of a combustion process with a multitude of sophisticated techniques, often using lasers. The extended knowledge on combustion phenomena gained by a
The HELLP (Hemolysis, Elevated Liver enzyme, and Low Platelet) syndrome requires close monitoring of rapid changes in hemostasis. A bedside viscoelastic test--Sonoclot--was used together with coagulation, liver and hemolysis laboratory analyses in three parturients with the HELLP syndrome up to 10 days postpartum. Principal component analysis (PCA) was used to reduce the dimensionality of this mul
Popular Abstract in Swedish Avhandlingen handlar om naturföreställningar i resereklam och bland re-senärer. Syftet var att analysera hur natur framställs i reklambilder för resor, vad reklamens framställning av natur har för betydelse för vad resenärer vill uppleva och upplever i samband med sin resa samt med vilka argument och bilder resenären själv väljer att återskapa upplevelserna av sin resa It is commonly believed that we live in a culture that is increasingly permeated by visual images. One category of images that we encounter everyday in different media, and that constitutes a large and growing part of media content, is advertisements. Advertisements also have a specific purpose and the images represent, make meaning of, and convey sentiments about phenomena. In this dissertation,
Popular Abstract in Swedish Studien presenterar en relationell ansats till förhandlingar, dvs en förhandlingsanalys i vilken relationerna mellan aktörerna står i centrum. Det innebär att istället för att se till enskilda förhandlares strategier etc, läggs tonvikten vid att förstå interaktionen mellan förhandlarna. Således har studier som söker slå fast nationella särdrag eller kulturellt betingadeThis study proposes the relational approach to negotiations to further our understanding of the negotiation relationship. At the center is negotiators' outlook on the other and themselves in East-West cooperation projects. This approach to negotiations is pluralist. Consequently, a number of theories have been utilized. First, using feminist theorizing in philosophy and International Relations, th
Popular Abstract in Swedish Teknikutvecklingen leder till att vi får allt mer avancerade elektroniska medicinska implantat. Dessa spänner idag från den välkända hjärtpacemakern till avancerade hörselimplantat, hjärnstimulatorer och implanterbara medicinpumpar. Med de allt mer avancerade implantaten har också deras behov av att ta emot styrsignaler från utsidan av kroppen, och deras förmåga att sänWith the increased sophistication of medical implants, there is a growing need for flexible high-speed communication with the implant from outside the body. Today the communication is done by an inductive link between the implant and an external coil at a low carrier frequency. Extended range and communication speed are possible to achieve by increasing the carrier frequency and the bandwidth. One
A measure of coherence is said to be truth conducive if and only if a higher degree of coherence (as measured) results in a higher likelihood of truth. Recent impossibility results strongly indicate that there are no (non-trivial) probabilistic coherence measures that are truth conducive. Indeed, this holds even if truth conduciveness is understood in a weak ceteris paribus sense (Bovens & Har
Popular Abstract in Swedish Fasoxidbränsleceller (eng. SOFC) är en keramisk bränslecellstyp som arbetar vid höga temperaturer. Genom att utnyttja energin hos avgaserna från en SOFC i en annan kraftvärmeprocess kan man erhålla ett s.k. hybridsystem som når höga verkningsgrader. Ett koncept som studerats i denna avhandling är en SOFC i kombination med en gasturbincykel (SOFC/GT). Eftersom bränslecelSolid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. The fuel cell, being the more efficient power generator of the two, represents the maj
