A Decomposition Approach to Multi-Region Optimal Power Flow in Electricity Networks

We present a decomposition approach to a class of social welfare optimization problems for optimal power flow in multi-region electricity networks. The electricity network is decomposed into multiple regions which decide independently over the amount of power produced within the region and exchanged with neighboring regions. We decompose the overall power flow (or social welfare) optimization into

Evaluation of UHT milk processed by direct steam injection and steam infusion technology

UHT direct steam injection and steam infusion are widely used; however there is no comparison of their impact on milk components. This study evaluates the structural changes at different steps during the UHT processing of whole milk in a full-scale UHT plant by transmission electron microscopy (TEM) and particle size measurements, and follows the enzymatic activity. The results of structural anal

Reel Socialism : Making sense of history in Czech and German cinema since 1989

Popular Abstract in English Reel Socialism considers the representation of the communist past in Czech and German cinema after the end of communist rule. The study offers in-depth analyses of numerous feature films, from Oscar-winning box-office hits to half-forgotten art-house offerings. It takes account of the films’ historical and political contexts and thus provides a comprehensive assessment This thesis is a comparative study of the communist past as depicted in Czech and German feature films since 1989, or ‘reel socialism’. It is the first detailed study of post-1989 Czech history films and the first comparative study of German post-reunification cinema. It demonstrates that cinema has been a vehicle of similar sense-making processes in the two history cultures. Much of the research

Explaining the Adoption of Complex Innovations by Reflexive Agents - A Critical Realist Perspective

The adoption of innovation is a multifaceted and dynamic phenomenon. It occurs as a result of the interplay between structural influences and agents' activities. Although existing studies on innovation have recognised the importance of theories that link the structure, the macro level, and agency, the micro level, in explaining changes over time, few theoretical accounts support the integrations o

Blood pressure, renal functional and structural changes, in normal and preeclamptic pregnancy

Popular Abstract in Swedish Njurarna spelar en central roll i de förändringsprocesser som anpassar kvinnans kropp till en graviditet. Många av de förändringar som sker mot slutet av en normal graviditet, påminner om de förändringar man ser vid preeklampsi, havandeskapsförgiftning, om än mindre uttalade. Preeklampsi är ett allvarligt risktillstånd som kan uppkomma under graviditet och en av de störThe kidneys play a pivotal role in the adaptive physiology of the pregnant woman, presenting some changes at term similar to the changes found in preeclampsia – a state of increased risk of fetal and maternal morbidity and mortality. The aim of these investigations was to explore possible similarities in blood pressure regulation, renal function and structure in normal term and preeclamptic pregna

Fackliga organisationer och medlemmar i dagens Sverige

Bokens baksidestext: Fackligt medlemskap har länge varit självklart i det genomorganiserade Sverige. Så är det inte längre. Under de senaste femton åren har andelen fackligt anslutna fluktuerat betydligt kraftigare än tidigare, även om den svenska organisationsgraden fortfarande är mycket hög. Ett nytt fenomen är att allt fler nöjer sig med att bara tillhöra a-kassan. Utifrån en brett upplagd inte

Handledning som undervisningsform i sjuksköterskeprogrammets praktik : en beskrivning av variation i innebörd

Popular Abstract in Swedish Företeelserna handledning och lärande har en diffus innebörd i vardagliga sammanhang, såväl som i utbildningssammanhang. Individer uppfattar företeelser och ord på olika sätt. Man ger dem en mening utifrån sin erfarenhet eller brist på erfarenhet. Denna studie belyser den mening som en grupp sjuksköterskestuderande och deras handledande sjuksköterskor ger handledning, sSwedish nursing education has its roots within a tradition of vocational training in clinical practice. Supervision is commonly used in the practical parts of the education. The aim of the study was to explore, describe and understand the content and meaning of supervision expressed by student nurses and their supervisors. A complementary aim was to analyse and report on the research process as a

Atmospheric atomic mercury monitoring using differential absorption lidar techniques

Three-dimensional mapping of atmospheric atomic mercury has been performed with lidar techniques, to our knowledge, for the first time. Industrial pollution monitoring, as well as measurements of background concentrations, is reported. High-efficiency frequency doubling of narrowband pulsed dye laser radiation was employed to generate intense radiation at the mercury UV resonance line. Field measu

Oppositely Charged Polyelectrolytes in Solution

This thesis is about the formation of complexes in solutions of oppositely charged polyions. We consider mainly three topics: 1)Monte Carlo simulations of oppositely charged polyelectrolytes with a focus on cluster compositions. To explain the distribution of cluster compositions, we found a minimum set of rules describing the interplay between the energy and entropy. 2)An analytical theory. The
