Quantum Coherence for Light Harvesting

Popular Abstract in English The main reason that we humans exist at all is because of photosynthesis. The food we eat, the oxygen we breath, most of the energy that warms our homes and powers our electronics are all products of photosynthesis. Over millions of years, plants, algae and some bacteria have developed biomachinery to harness solar energy and thrive. They do this by fixing carbon into cAlmost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. The reaction center is responsible for trans-membrane charge separation, which generates a proton motive force which drives al

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

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

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

En bonadsmålare och hans värld. Johannes Nilsson i Breared

Popular Abstract in Swedish Studien behandlar den sydsvenske bonadsmålaren Johannes Nilssons måleri. Denne produktive målare levde och verkade i Breareds socken i södra Halland 1757­1827. En analys av hans bonader visar att han i många stycken frångick sina föregångares traditionella, imiterande framställning och begränsade motivkrets. Den övergripande frågan i avhandlingen är: varför målade JohanThe aim of this dissertation is to find relationships between folk art, an artist's personal life and influential factors originating in the context. Christmas wall hangings by the peasant painter Johannes Nilsson (1757­1827) are the focus of the study. The fact that he had a special approach to the painting tradition raises two questions: Why did he paint the way he did? How can his hangings be i
