Popular Abstract in Swedish Denna doktorsavhandling är en delstudie i ett större projekt som syftar till att utveckla Artificiell fotosyntes för att framställa ett värdefullt bränsle, vätgas, från solenergi och vatten. Vår typ av Artificiell Fotosyntes syftar till att framställa syntetiska “superämnen” som kan härma nyckelsteg i den naturliga fotosyntesen. Våra artificiella ”superämnen” skall kunnIn natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. The energy is later stored in form of energy- rich substances formed in reductive biosynthetic reactions. The electron

During the last decades, Ingvar Johansson has made a formidable contribution to the development of philosophy in general and perhaps especially to the development of metaphysics. This volume consists of original papers written by 50 philosophers from all over the world in honour of Ingvar Johansson to celebrate his 70th birthday. The papers cover traditional issues in metaphysics and the philosoph

Within the framework of the Swedish national trial with Intelligent Speed Adaptation (ISA) in urban areas, the effects of large scale use of “active accelerator” were evaluated. 284 cars were equipped with the system for a period of 5-11 months in the city of Lund. The driving data of all equipped vehicles were logged with regard to time and speed, both before and after activating the system. Driv

Abstract in UndeterminedObjective To investigate acute posttraumatic reactions and forms of coping to the September 11 attack. Method A Web TV nationwide, representative sample of individuals 13 years or older (N=3134) was evaluated within three weeks of the attack. Measures included the SASRQ, the brief version of the COPE, and questions about demographics and attitudes toward the attackers. Resu

The general goal of this thesis is to elucidate children’s early understandings of pictorial meanings, and how one can know anything about them. My central aim is to explore how picture comprehension develops during children’s first 3 years of life, through semiotic-theory-derived analyses of meaning relations. In so doing, I hope to contribute to the study of both semiotic theory’s psychological

Popular Abstract in Swedish Efterfrågan på shikimsyra, vilken återfinns i biosyntesvägen för bl.a. de aromatiska aminosyrorna tryptofan, fenylalanin och tyrosin, har under de senare åren ökat. Orsaken till detta är mestadels att den är råmatrial till antiinfluensamedicinen Tamiflu?. Den ökade efterfrågan har drivit fram nya tillverkningsmetoder såsom produktion via E.coli- fermentation. Även om maShikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E.coli strain was made in the current work in order to increase the understanding of shikimic acid production and identify mean

A fully integrated 1.2V 0.25 μm CMOS quadrature frontend for a low or zero IF receiver has been designed and measured. The front-end consists of a common-gate LNA, a quadrature passive mixer, and a quadrature VCO operating at 1.8GHz. The conversion gain is 16dB, the noise figure is 6dB, the CP₁ is -18dBm, the IIP₂ is 27dBm, and the IIP₃ is -6dBm. The total power co

We investigate the bandwidth and distance of codes created by ordinary lowpass filtering of a pulse stream. The encoder is thus a convolution, but over the reals. Performance of these codes is compared to the TCM and PRS code families; despite their simplicity, the new codes perform equally well. Since a simple decoder exists, these are attractive codes.

Changes in evolving software systems are often managed using an issue repository. This repository may contribute to information overload in an organization, but it may also help navigating the software system. Software developers spend much effort on issue triage, a task in which the mere number of issue reports becomes a significant challenge. One specific difficulty is to determine whether a new

The political objectives on national and international levels towards a larger proportion of renewable energy require considerable planning activities on a local level. These activities inevitably must relate to the local community and its various groups; their culture, economy, social activities as well as their views on environmental problems and nature values. This applies to all energy plants.
