Popular Abstract in Swedish De mekaniska egenskaper som torv normalt besitter gör att den lämpar sig dåligt som undergrund för vägkroppar. Det gängse förfaringssättet har därför varit att gräva ur torven och ersätta den med sprängstensmassor. Vid masstabilisering lämnas torven däremot kvar och dess egenskaper förbättras genom inblandning av något kemiskt bindemedel, företrädesvis cement eller olikPeat is badly suited as a base for road and railway embankments due to its geotechnical properties. The usual procedure has been, therefore, to excavate peat and replace it with blasted rock. During mass stabilization, the peat is left behind and its geotechnical properties are improved through mixing with a chemical stabilizer, preferably cement or cement in combination with different by-products

This essay deals with mythologizing as an inherent part of historiography, and as a way to imbue the past with meaningfulness, with focus on the commemoration of the Holocaust, the Nazi genocide on European Jewry.

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 consumption is 9.6mW and the IF qua
