The overarching objective of the studies in this thesis is to solve issues associated with the current district heating development in order to improve the efficiency, and thus the environmental performance, of district heating systems. More specifically, the aim is to solve issues related to prosumers and bottlenecks in district heating networks. Prosumers are consumers who also produce district The overarching objective of the studies in this thesis is to solve issues associated with the current district heating development in order to improve the efficiency, and thus the environmental performance, of district heating systems.

This thesis concerns assessment of acoustic comfort in apartment buildings. A new approach is followed, beyond noise annoyance investigation, which was the typical path so far. The latter involved acoustic descriptors, which characterize the structural components, being associated to self-reported noise annoyance.A socio-acoustic survey was conducted in 34 Swedish and Danish structures including 1

This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular info

Popular Science SummaryPolymers are giant molecules consisting of a repetition of many small units (monomers) that are linked together by chemical bonds. If we consider a long necklace as a polymer chain, the beads are the monomers and the part of the thread which connects the beads together is the chemical bond. Polymers are important materials in our everyday life and they can be found e.g., in This thesis incorporates studies on the aqueous systems of two types of thermoresponsive amphiphilic block copolymers; a series of nonionic triblock copolymers comprising blocks of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) denoted as PEO-PPO-PEO block copolymers, and a series of ionic diblock copolymers consisting of one charged block and one block of poly(N-isopropylacrylamide) (

The possibility that structural changes in international trade might impact countries differently has been a matter of great concern for many observers from the 1950s onwards, and the view that the specialisation pattern of a country in international trade matters for its economic performance has been widespread. This paper analyses the structural changes in international trade from the 1960s omwa

We investigate four different methods for background estimation in calcium imaging of the insect brain and evaluate their performance on six data sets consisting of data recorded from two sites in two species of moths. The calcium fluorescence decay curve outside the potential response is estimated using either a low-pass filter or constant, linear or polynomial regression, and is subsequently use

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climate is, however, being questioned. Therefore more and more of these buildings are being built with double skin facades, which can provide: a thermal buffer zone, energy savings, wind protection with open windows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, polluta

Software development organizations are continuously looking for better ways to manage their projects. An emerging approach to achieve this is Inner Source, which refers to the adoption of Open Source development practices within the confines of an organization. With an Inner Source approach, individuals, teams, and departments within an organization can start software projects, very similar to the

The quantification of species along environmental gradients has long been the subject of study regarding natural plant communities and, more recently, ecosystems disturbed by anthropogenic emissions of eutrophying and acidifying substances. We studied 527 sites in southern Swedish deciduous forests divided into two regions, with mean nitrogen depositions of 17 and 9 kg ha(-1) y(-1). The higher dep

The oxygen-atom transfer reaction catalyzed by the mononuclear molybdenum enzyme dimethyl sulfoxide reductase (DMSOR) has attracted considerable attention through both experimental and theoretical studies. We show here that this reaction is more sensitive to details of quantum mechanical calculations than what has previously been appreciated Basis sets of at least triple-zeta quality are needed to

Studies suggest that skin cancer aggregates within families; however, the risk of skin cancer associated with having an affected sibling or parent by subtype, tumor site, and age at diagnosis has not been established. The 2006 update of the Swedish Family-Cancer Database was used to calculate standardized incidence ratios (SIRs), representing the ratio of cancer risk among individuals with affecte

Popular Abstract in English 111-Indium is a radioactive isotope that can be chemically linked to different molecules. When this compound is given to patients is distributed heterogeneously within the structures that build up the testicle. Different parts of the so-called germ cells are sensitive to radiation in different ways. Therefore, if a radioisotope that send out electrons with low energies It is well known that the testicles are among the most radiosensitive tissue, and constitute an important critical target for both external and internal radiation during diagnostic and therapeutic use of radionuclides. In systemic radionuclide therapy where very high activities are administered, the testis may become a dose-limiting organ; often with a complex, non-uniform activity distribution an

Departing from three metaphors—the body as gift, resource, and commodity—the book explores the contemporary exchange of organs, tissues, and cells. Although the gift is the sanctioned metaphor for donating parts of the body, the underlying perspective from the side of states, authorities, and the medical establishment often seems to be that the body shall be understood as a resource. But medicine,

In today society people live longer and along with the rising life expectancy chronic diseases, like dementia, will become more common. The demand on more and better assistive technology, technology that ease the everyday life for the persons with dementia, will increase. The assistive technology currently recommended by occupational therapists are mainly low-technological solutions. There exist

This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E.ON is to have a more precise way to estimate the energization consequences of increasing the transformer size in the grid, since currently is being used a rule of thumb that relates the trans

Abstract (Swedish) Vägföreningen Vikhögs Uddeväg har under lång tid upplevt problem och risker med kusterosion för sin privata väg. Denna studie ämnar utreda vilka förutsättningar som ligger bakom problemen och hur problemen kan utvecklas i framtiden. Studien ämnar också undersöka vilka resurser som finns tillgängliga i samhället för små kustsamhällen att använda sig av för att skydda sin egendom

Mer än 10% av Sveriges befolkning lider av någon fobi och detta projekt studerar möjligheten att lindra akrofobi (höjdskräck) med hjälp av virtual reality (VR). Arbetets syfte är därför att undersöka hur man på bästa sätt kan lindra akrofobi med hjälp av VR. Frågeställningarna som skulle besvaras var: ”Kan man med hjälp av enbart visuell och auditiv feedback skapa en trovärdig miljö för att lindraMore than 10% of Sweden's population suffers from some kind of phobia and this project is studying ways to ease acrophobia (fear of heights) with virtual reality (VR). Therefore, the purpose of the work was to investigate how to best ease acrophobia with help of VR. The research questions to be answered were: "Is it possible with just visual and auditory feedback to create a credible envi
