Amphiphilic polymers consisting of copolymethacrylates carrying about 26 wt % ethylene oxide [(EO)(n)] side chains of different lengths were used as matrices in gel electrolytes. The gel electrolytes were composed of 30 wt % copolymer and 70 wt % 1 M LiPF6 in a mixture of ethylene carbonate and gamma -butyrolactone (2/1 w/w). The coordination of lithium ions by the (EO)(n) side chains in competiti

Interpopulation comparisons of variation in resource availability and in allocation patterns along altitudinal and latitudinal gradients allow insights into the mechanisms shaping the life history of animals. Patterns of between-population differences in female life history traits have been studied intensively across a wide range of taxa, but similar investigations in males have remained scarce. T

This study investigates the impact of rules of origin (ROO) on the Malagasy textile and clothing industry. The ROO of two different preferential trading arrangements for developing countries, the African Growth and Opportunity Act (AGOA) of the US and the Lomé/Cotonou agreement of the EU, are compared and related to Malagasy clothing exports and textile imports. The AGOA ROO are found to be more l

This thesis explores the interactions between tourism development and cultural values in the South Pacific nation of Samoa. As tourism is likely to remain a key strategy for the development of Samoa, this study explores the impact of such development on the cultural component of fa’a Samoa, or Samoa’s way of life, which varies quite significantly from Western, capitalist culture. The aim of the st

Earlier, linguists have treated conceptual metaphor and conceptual blend as two separate phenomena. Recent research, however, has brought more and more attention to similarities between these phenomena. This study intends to shed more light on such similarities in the underlying creation process and aims to detect common preconditions. A corpus-driven analysis, incorporating 50 advertisements repr

Denna uppsats belyser de ökande rättsverkningarna det digitala samhället har på upphovsrätten. Framför allt har principen om konsumtion av upphovsrätt, ett undantag på en författares ensamrätt att sprida sitt arbete, erhållit en ny tolkning. Principen innebär att när en rättighetshavare placerar dennes upphovsrättsskyddade verk på marknaden till försäljning, är spridningsrätten konsumerad, vilket This thesis illustrates the increasing legal effects on copyright by the modern digital environment. In particular, the principle of copyright exhaustion, the exception to an author’s exclusive right to distribute his or her work, has been targeted with a novel interpretation. The principle ensures that when a right holder puts his/her copyrighted work on the market for sale, the distribution righ

Background Today’s diffusion of innovation theories are primarily based on the studies conducted up until 1991, which means that they have not taken the new Internet economies into consideration. When considering the enormous impact the Internet has had since its introduction, it stands to reason that there has also been an impact on how innovations diffuse in the marketplace. Problem definition A

By regressing volatility series of equity returns on macroeconomic variables using data from the Nordic countries, three conditional volatility models are evaluated on their ability to capture effects of long-run volatility shocks. In addition, the same models' short-run forecasting performance is tested by employing a rolling window approach. The results suggest that none of the models are su

Study on value creation for acquiring companies in Sweden in the years 2002-2009. The study is carried out by using both event- and accounting study methodology and the value creation is studied in short, medium and long-term. We find significant positive average abnormal returns of 2.82% at the announcement, which is steady until 5 days post the announcement. We find no significant abnormal chang

This thesis explores the state of regional cooperation, particularly in the field of security, among Denmark, Finland, Iceland, Norway and Sweden (Norden). The author examines correlation between a set of socially constructed factors and the creation of a common Nordic profile in a regional security organization, the OSCE. Formally, Norden is divided in the EU and the non-EU members, but unofficia

Synthetic estrogens that originate mainly from oral contraceptive pills reach our waters through sewage effluent and potentially affect organisms in the natural environment. This study focused on the effects of the synthetic estrogen 17-alpha-ethinylestradiol (EE2) on the foraging and predator avoidance behaviors of the planktivorous fish roach (Rutilus rutilus), a common fish in Swedish lakes and

New high-efficiency power cycles and environmentally friendly cycles have introduced combustion atmospheres that differ from the traditional hydrocarbon-air mixtures. Wet cycles, solid oxide fuel cell with a gas turbine (SOFC-GT), CO₂ separation/capture and biogas combustion are processes that involve high concentrations of inert gases such as H ₂O, CO₂ and N₂

This memo reports on factors that drive and inhibit the digitalization of security systems. The reported factors are as follows: Technology-push factors • Need to lower costs on the end-user side, i.e. replacing labour with technology • Perceived convenience and ease-of-use of digital systems • Digital products can be connected to the current enterprise network; enabling an expanding set of secur

In order to prepare for the potentially negative influence of insertion devices (IDs) on beam lifetime, injection effi- ciency and beam size in the MAX IV 3 GeV storage ring, a strategy for neutralizing the foreseen effects of the IDs has been developed. The strategy involves a local correction of the betatron phase advance by adjusting the strength of the quadrupoles adjacent to the ID as well as

Several contrasting effects are reported in the existing literature concerning the impact assessment of the COVID-19 outbreak on the use of energy in buildings. Following an in-depth literature review, we here propose a GIS-based approach, based on pre-pandemic, partial, and full lockdown scenarios, using a bottom-up engineering model to quantify these impacts. The model has been verified against

The low-temperature combustion (LTC) is an attractive concept that enables the modem combustion engines to move toward sustainability mainly by increasing the efficiency and decreasing the emissions. The modern combustion engines which are working based on the LTC concept have specific fuel requirements. Fuel ϕ-sensitivity is a key factor to be considered for tailoring fuels for these engines. Fue

The Baltic Sea highly susceptible to the proliferation of Phytoplankton blooms. Present work examines the long-term trend and spatio-temporal variability of satellite derived chlorophyll concentration (Chl a) in the Baltic Sea during the period 2004–2021. Furthermore, the influence of water quality and meteorological parameters on Baltic Sea primary productivity has been analyzed using robust Gene
