Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Att ?sexta? innebär att med textbaserade digitala medier kommunicera med sexuella partners, vilket är en praktik som kan upplevas väldigt intim trots mediets begränsningar av de karaktäristiska dragen av en fysisk interaktion. Denna studie har som syfte att ge en övergripande bild över hur denna typ av interaktion konstrueras och tar sig uttryck, vilket görs i en tredelad undersökning som fokuserar på kommunikationsmönsterna och hur dessa reflekteras över. Det empiriska materialet utgörs av 18 bidrag insamlade via en nätbaserad deltagande observation, 2 kvalitativa intervjuer och 56 svarande på en nätbaserad enkät. Genom ett självselektivt urval avgränsades den studerade gruppen till i huvudsak informanter med en medianålder på 27 år med erfarenheter av heterosexuella relationer.

The aim of this investigation is to explain present and historical differences in the Swedish and Danish unemployment rates between 1976 and 2005 with a broad framework, making use of neoclassical and post-keynesian economic theory. The influence of the rate of investment to GDP, and various institutional factors are assessed in quantitative analysis. It is suggested that the crude answer of the question asked in the title, ?What is it that Denmark does that Sweden does not??, is that Denmark invests. This investigation suggests accordingly that the main reason of the relative labour market success during the 90?s in Denmark was a rising, and rapidly recovering, rate of investment to GDP, and perhaps not primarily its flexible labour market institutions.

The SAB-system (Klassifikationssystem för svenska bibliotek) was created almost a hundred years ago and has often been viewed as insufficient among many academic libraries. KB (Kungliga Biblioteket) has therefore decided to change to DDC (Dewey Decimal Classification) which means that the Swedish libraries are now facing a challenge that involves a change to a new classification system. This is a comparable situation that occured when the SAB-system was created. The aim of this Master?s thesis is to examine the Swedish library sector´s approach to a new classification system, first to the SAB-system and then to DDC.

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.

Alla företag strävar efter att göra en vinst, men frågan är när ett företag faktiskt uppnått detta. Stern Stewart & Co är ett amerikanskt konsultbolag som har arbetat fram ett koncept som de kallar Economic Value Added (EVA). Den stora skillnaden mellan detta och övriga vinstmått är att EVA visar att ingen vinst har uppnåtts förrän även kostnaderna för det egna kapitalet, d.v.s. den avkastning som aktieägarna förväntar sig, är täckta. Stern Stewart & Co har marknadsfört EVA som ett helhetskoncept som ska användas för styrning i hela företaget.

The analysis of regional development and the formation of regional policy have experienced an increasing importance in Europe and in Sweden during the last decades. There is a widespread assumption that the increasing significance of regions is due to the diminishing role of the nationstate in the era of globalization. This essay suggests that there is a hegemonic discourse, heavily relying on the assumptions of New Regionalism, when addressing regional building. Sometimes described as an ideology, New Regionalism, which is derived from research of successful regions, is based on the assumption that regional competitiveness and autonomy creates economic growth. The Committee on Public Sector Responsibilities (Ansvarskommittén) suggests that Sweden requires new regional structure, due to the increasing expenditures facing the welfare state.

The purpose of this essay is to review the Swedish international development cooperation carried out by Sida to control whether the implementation of the international aid is compatible with the policy. There are a lot of different ways to implement the economic aid that are being used by the donors today. The Swedish method has since the 1960s mainly been focused on attempting to diminish the poverty in the world. In the latest time another goal has been added, that is a focus on supporting the civil rights. This essay will be concentrated to aim on what kind of countries receiving aid from Sweden, and exactly why these countries are being chosen.The main question of this essay is: What countries are receiving the international developing aid, and how can this distribution be understood? To answer the main question there are two themes in the essay:? What kind of countries is supposed to receive developing aid from Sweden according to the policy?? What kind of countries is receiving the aid, and how can this be understood?This essay is mainly based on quantitative data obtained from Sida, together with index of corruption and poverty will the different types of Swedish cooperation countries be described.The conclusions of this essay are that there are two objectives of the policy: to fight poverty, and to strengthen the civil rights.

The 3:12-provisions are part of a legal system specified for owners of close corporations (companies owned and managed by a small group of businesspeople), for taxation of capi-tal gains and dividend. The reason for special rules for the taxation of these owners is to prevent them from transforming their income, to only be subject of the lower taxation of capital gains, instead of income of service. Since the rules were put in force, they have been subject to several changes. The most recent changes took effect on the 1 January 2006. They involve a higher importance for the rule of salary-based taxation.

This thesis intends to examine the role of the city, Dublin, in the Irish economic growth during the 1990s. It is a case study where Dublin is compared with current theories on post modern cities as growth machines and increasingly prominent actors in the global context. The study has an interdisciplinary approach but focuses on political science issues such as power distribution, global-local governance and local political organisation. It is a theory driven study that also intends to add aspects to the understanding of the cities of our time. I argue that Dublin has faced a lot of changes during the last decades in accordance with the post modern city.

People are constantly using there friends in order to ask for a favor or to get hold of some information. This is usually done unconsciously and it is just viewed as everyday life behavior. The function and the use of these links definitely have a value, which means that it can be viewed as a form of capital. But this capital is not caught in the traditional theories of physical capital or human capital; it demands it?s on theorization.

På senare år har den finansiella marknaden vuxit enormt mycket. I samband med värdepappershandel utsätts banker och andra finansiella aktörer för risker. För att få en kontroll på lönsamheten och inte utsättas för likviditetsproblem, har insikt om riskkontroller förbättrats. Value at Risk (VaR) är ett mycket erkänt och användbart mått vid riskmätningar. VaR definieras som ?den med viss sannolikhet förväntade förlusten från ogynnsamma marknadsrörelser över en definierad tidsperiod?.

Med intern könssegregering menas att kvinnor och män arbetar inom olika specialiteter av ett yrke. Ett yrke som har en jämn könsfördelning kan därför ändå vara starkt segregerat. Könssegregering kan innebära problem i form av till exempel effektivitetsförluster, privatekonomiska förluster och ojämn maktfördelning. Syftet med studien är att undersöka om intern könssegregering förekommer bland yrken som varit mansdominerade, men som idag har en betydligt jämnare könsfördelning. Hur segregeringen har påverkats av att andelen kvinnor ökat inom yrket och om det finns en koppling mellan lönenivå och andel kvinnor inom en specialitet undersöks.

Sedan Ukrainas självständighetsförklaring 1991 har landet arbetat med att reformera sin ekonomi till ett mer marknadsekonomiskt system. Denna process innefattar en mängd olika aspekter att ta hänsyn till som har stora effekter på ekonomin. I denna uppsats har vi valt att analysera en del av de otaliga reformer som finns, nämligen hur väl Ukraina har lyckats med sina skattereformer i syfte att införa marknadsekonomi i landet. Dessutom ämnar vi besvarafrågan vilka effekter som skattereformerna har haft på landets ekonomi med fokus på hur statens intäkter förändrats samt utvecklingen av den makroekonomiska variabeln inflation ochlandets budgetunderskott. För att kunna besvara den förstnämnda frågan har vi använt oss av befintlig teori om den finanspolitiska transformationsprocessen samt analyserat skattebördan, skattestrukturen samt skattesatserna i Ukraina.

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.
