This is a thesis about interdisciplinarity, scientific integration, and problem solving in sustainability science. Sustainability science is an emerging and highly interdisciplinary field that seeks to integrate vastly differentiated bodies of knowledge in addressing the challenge of transitioning contemporary societies towards sustainability. Interdisciplinarity is paramount. Interdisciplinarity

The aim of this study is to investigate whether the occurrence of lexical tones in a language imposes restrictions on its pitch range. Kammu, a Mon-Khmer language spoken in Northern Laos comprises dialects with and without lexical tones and with no other major phonological differences. We use Kammu spontaneous speech to investigate differences in pitch range in the two dialects. The main finding i

Abstract in Italian Questo progetto di tesi prevede un lavoro di osservazione analisi e costruzione di una struttura comunicativa su Second Life al fine di stimolare, attraverso una serie di contenuti di natura archeologica, l’incontro e la collaborazione di ricercatori studenti e appassionati provenienti da tutte le parti del mondo. Per poter organizzare una struttura comunicativa utile a questo

Attofysik handlar om att öppna ögonen för en värld som vi länge vetat fanns men fram till nu inte har kunnat se – elektronernas värld. En värld av ofattbart små och snabba förlopp och fenomen. Utvecklingen av lasertekniken har kommit så långt att vi faktiskt har möjlighet att studera den världen.

The advent of 2.5 and 3G networks mark the beginning of the mobile Internet. The investments in these technologies will be the largest in the history of telecommunication. However, their success will largely depend on the availability of successful services and initially these will largely constitute existing services. These services all reside in the current IPv4 address space which make them ina

This thesis describes tetrapyrrole synthesis in the aerobic Gram positive bacterium Bacillus sub-tilis. Tetrapyrroles such as heme of a-, b-, c-, d- and o-type can be synthesised in this organism. In addition, there is strong evidence for the presence of the tetrapyrrole siroheme in B. subtilis. Heme b (protoheme IX) and siroheme are synthesised in ten and nine enzymatic steps, respectively, from

An ASIC implementation of the K-best Schnorr-Euchner decoder is presented for a 4/spl times/4 16-QAM MIMO system. There are several low complexity and low power features incorporated in the proposed VLSI architecture. The chip is fabricated in a 0.35-/spl mu/m CMOS technology. The chip core area is 5.76 mm/sup 2/ with 91 K gates. Furthermore, the decoding throughput that the chip can support is up

The rapid development of the technology of today increasingly involves the design and fabrication of devices of smaller and smaller dimensions, down to the atomic length scales. At the nanoscale molecular dynamic (MD) models are often used. For many but the smallest systems, MD models are computationally too expensive, whereas classical continuum mechanics models not accurately can resolve microsc
