This disquisition explores the possibilities to install a battery storage situated in a gasturbineplant to enable a start up of the gasturbine in the case of a powerfailure. Since powerfailures are rare, the battery will mostly and to a large extent be unused, this creates an economic dilemma. Uniper has taken in and recieved a tender which includes and discribes a battery with a larger storage sy
A divergence in labor productivity growth rates in the services sector has been observed between in particular the euro-area members and the US since the mid-1990’s. The study addresses the question whether deregulation of the telecoms sector contributed to economic development through an elevated effect of ICT capital. The study finds ICT capital to have a positive effect on both real GDP growth
In this thesis we employ the method of eigenfamilies in order to construct explicit examples of complete minimal submanifolds in the classical non-compact Riemannian symmetric spaces $$\SLR n/\SO(n),\ \Sp(n,\R)/\UU(n),\ \SO^*(2n)/\UU(n),\ \SU^*(2n)/\Sp(n).$$ In each case, we produce a multidimensional parametrized family of complete minimal submanifolds of codimension two. The results form a conti
Populärvetenskaplig sammanfattning: Världens hav är av största betydelse för jordens klimat. Totalt är 71 % av jordens yta täckt av vatten. Den mesta av den inkommande solstrålningen, som når jordens yta, upptas av haven. Havens värmekapacitet och cirkulation medför att de både kan lagra och transportera denna värme, innan den återgår till atmosfären och strålar tillbaka ut i rymden. Den termohaThe world ocean is of great importance for the Earth’s climate system, and affects climate in a number of ways. Approximately 71 % of the Earth’s surface is covered by oceans. Most of the solar radiation is received by the ocean. The heat capacity and circulation of the ocean makes it possible to both store and redistribute this heat before it returns to the atmosphere and radiates back into space
Populärvetenskaplig sammanfattning: För att öka tillgången på mat och att generera arbeten och inkomster är det angeläget för utvecklingsländer att öka produktionen inom jordbruket. En förutsättning för detta är att eliminera produktionshinder genom att dels förbättra jordbruksmetoder, dels identifiera olika områden som är lämpliga för olika typer av jordbruk. Denna Minor Field Study (MFS) är utföThe importance of less developed countries to increase the agricultural production, in order to improve food supplies and generate employment and income, requires the removal of resources constraints by improving agricultural practices and identifying land suitable for different agricultural activities. This Minor Field Study (MFS) is made within the present Sida/SAREC-financed research project “R
Strategic alliances can be defined as contractual co-operations between two legally independent companies operating on the same horizontal level of the market and whose purpose is to strengthen the competitiveness of the undertakings concerned through the achievement of strategic competitive advantages. Having its origin in theories of business management, the term has over the last decade become
This paper aims at providing a detailed analysis of the leading indicator properties of corporate bond spreads for real economic activity in the euro area. In- and out-of-sample explanatory power of corporate bond spreads on economic growth is examined along four dimensions: the industry sector – i.e. distinction between financial and non-financial corporations, the bonds‟ credit ratings and their
We prospectively evaluated a combination of fungal biomarkers in adult haematology patients with focus on their clinical utility at different time points during the course of infection. In total, 135 patients were monitored once to twice weekly for serum (1-3)-ß-d-glucan (BG), galactomannan (GM), bis-methyl-gliotoxin and urinary d-arabinitol/l-arabinitol ratio. In all, 13 cases with proven or prob
Objectives To assess the impact of extra-articular spondyloarthritis (SpA) manifestations (anterior uveitis, psoriasis and inflammatory bowel disease (IBD)), and of comorbidities, on tumour necrosis factor alpha inhibitor (TNFi) drug retention in ankylosing spondylitis (AS). Methods We identified all bio-naïve patients with AS starting a first ever TNFi July 2006 to December 2015 from the Swedish
Despite their tiny brains, insects show impressive abilities when navigating over short distances during path integration or during migration over thousands of kilometers across entire continents. Celestial compass cues often play an important role as references during navigation. In contrast to many other insects, South African dung beetles rely exclusively on celestial cues for visual reference
Recent years have proven the benefits of electrifying the road bound vehicle fleet. With new components entering, the general understanding as well as the components as such needs to be improved. Focus in the thesis is on the design of an electric machine based on specifications of requirements for a commercial heavy vehicle such as a truck or a bus. One strict requirement is that the machine has
Research infrastructures play a key role in launching a new generation of integrated long-Term, geographically distributed observation programmes designed to monitor climate change, better understand its impacts on global ecosystems, and evaluate possible mitigation and adaptation strategies. The pan-European Integrated Carbon Observation System combines carbon and greenhouse gas (GHG; CO2, CH4, N
Fastigheter omfattar stora ekonomiska värden och för privatpersoner hör en fastighetsöverlåtelse ofta till en av de stora affärerna man gör i livet. Det är således viktigt att ansvarsfördelningen vid fel och brister i fastigheten blir tydlig så att köparen, säljaren respektive mäklaren vet vilket ansvar som gäller. Detta ansvar regleras i jordabalken och i fastighetsmäklarlagen. För köparen innebäProperties represents great economic value and a property acquisition can be the biggest transaction one will do in a lifetime. Transparence regarding the defect-rules are therefore of great importance. According to the Swedish Land Code the buyer has a duty to examine. This thesis purpose is to define the current legal situation regarding this duty, as well as if a duty to inform exists for the s
Today there are limited theories that consider the research subject relationship creation as a contributing factor to a company’s brand loyalty within an organizational marketing context. The purpose of this thesis is to contribute with knowledge about organizational relationship creation between distributors and retailers, and how these relationships are constructed through communication efforts.
In this project I have studied the effect of gas expulsion on the evolution of stellar clusters. What effect the rate of gas removal and the quantity of gas removed has on the evolution on the cluster will be studied through computer simulations with the NBody6 code and compared to analytical predictions. The rate at which gas is removed has a very significant impact on how the cluster evolves
The role of the artist is influenced by the development of society and is understood in its context hereby. My interest is to study tendencies as they reveal themselves in various ways, in the expressions by different actors in the art education, art community and art fields. My material is articles in media, in magazines, newspapers and also interviews concerning the ideas of the artist role. The
We have measured the land-atmosphere CO2 exchange using the eddy covariance technique in a high Arctic tundra heath in northeast Greenland (Zackenberg). On the basis of 11 years of measurements (2000-2010), it was found that snow cover dynamics was important for the CO2 exchange. The start of CO2 uptake period correlated significantly with timing of snowmelt. Furthermore, for years with deep and l
Background: Photoallergic contact dermatitis (PACD) is an uncommon condition, and there is a lack of validated criteria for its diagnosis. Objective: To identify a set of relevant criteria to be considered when suspecting a diagnosis of PACD and to assess the reproducibility of these criteria. Methods: This was a diagnostic item selection and reliability study performed between July 2012 and Octob
We present extensions to the agent-based agricultural policy simulator (AgriPoliS) model that make it possible to simulate the consequences of agricultural policy reform on farmers' land use decisions and concomitant impacts on landscape mosaic, biodiversity and ecosystem services in a real agricultural region. An observed population of farms is modelled as a multi-agent system where individual fa
