The topic of this thesis is the optimal control of transportation networks. The problem studied is a dynamical extension of a classical problem in economics, in which the objective is to distribute goods to maximize welfare, whilst satisfying constraints on production and consumption. The main contribution is to show that for a class of welfare functions and dynamics, the optimal control is highly
In order to identify the importance of different areas for nitrogen retention in the Lagoon of Venice, Italy, undisturbed sediment cores of different origin were collected in late April 1998. The cores were transferred to the laboratory and incubated for denitrification activity using the method of 'nitrogen isotope pairing'. The sampled sediments were collected in a freshwater stream (Stn A)I an
The healthcare sector constitutes a major part of the economy of developed nations and consumes significant quantities of consumables. The Region Scania commissioned IIIEE, Lund University, to develop a management tool for strategic decision-making in order to reduce the climate impact indirectly derived from material, consumption. The tool was streamlined to fit operational conditions at Region S

BACKGROUND: Our aim was to explore the reasoning and experiences of women when offered a self-sampling HPV test.METHODS: This study implemented a qualitative study design and content analysis using an inductive approach. Data consisted of written narratives collected through open-ended questions from a total of 173 women. Women were included if they had been offered a self-sampling device since Se
Using a mixed input–output model, this study examines potential changes in sector output and water requirements in Macedonia arising from climate change. By defining three climate change scenarios and exogenously specifying the warming shocks for five key agricultural sub-sectors, the effects on the economy were quantified. The results indicated that except for cereals and grapes, agricultural pro
Thesis Purpose: The purpose of this study is to explore young consumers' identity creation in the context of nostalgic consumption and marketing. The study seeks to deepen the understanding of how young consumers construct their identities by exploring the impact of two forms of nostalgia, personal and historical. Theoretical Perspective: To analyze the empirical data and gain insight into co
Recently, there has been considerable interest in the internal reforming reactions of solid oxide fuel cells (SOFCs) using methane or natural gas via. The internal reforming and electrochemical reactions appear in the porous anode layer, and may lead to inhomogeneous temperature and gas species distributions according to the reaction kinetics. A three-dimensional calculation method has been furthe

Bioactive compounds were investigated in genotypes (cauliflower 10, white cabbage 10, curly kale 1) and plant parts of the three crops. The content of most of the major glucosinolates glucobrassicin, sinigrin and glucoiberin differed significantly between cultivars. Samples harvested in 2000 had higher amounts of several glucosinolates than samples from 1999. Within cauliflower the buds of the flo
Stomach content analysis showed that Kyphosus sydneyanus collected by spearing from coastal reefs near Leigh, north-east New Zealand, is herbivorous throughout its post-settlement life. All size classes collected consumed a wide range of macroalgae, predominantly the phaeophytes Carpophyllum maschalocarpum and Ecklonia radiata, and the rhodophytes Gigartina macrocarpa and Caulacanthus ustulatus. M
Despite the efforts to reduce its water consumption, the food industry still requires large amounts of water. Membrane processes have established themselves in the food industry at the beginning of the water loop for preparation of the intake water and at the end water loop for recovery and final treatment of the water. The focus of this paper is on two application studies related to water recover
This article scrutinizes the role of structural change and foreign trade in the Nordic countries, except Iceland, in industrialization prior to 1914. Sector contribution to GDP as well as the role of the foreign trade is compared across the countries. The comparison uncovers different paths to industrialization that cannot be explained by reference to received views, such as the shock of free trad
Previous research has consistently found demographic responses to grain price fluctuations in preindustrial Europe, both at macro and micro level. Grain prices serve as a summary measure of the workings of the preindustrial economy, reflecting not only local harvest conditions but trade patterns and market integration. All over preindustrial Europe the manorial estate was an important institution
This chapter traces the main sustainability trends of the five countries analyzed in this book. The starting point is to understand sustainability as main measure of development, diminishing the role of GDP or Income. In order to address these concerns the chapter utilizes mainstream indicators such as NaturalResources Intensity and energy consumption, and adding new comprehensive measures of deve
