Fjärrvärme, vad annars? : Fjärrvärme och dess alternativ

AbstractBackgroundThe Swedish district heat market of today is a subject being discussed regarding the reasonableness of the heat district supplier?s price settings. The issue is currently on a government level where a new investigation is being executed at the time of writing. Many real estate owners are growing tired of the situation where the heat district suppliers are taking advantage of their monopoly position, thus feeling that the price of district heating has been increasing far too much for many years. The market can be described as a natural monopoly because the real estate owner has no possibility to choose another supplier if they are unsatisfied with the present.

Elektrolytlösningar som vätsketerapi hos mjölkkor med löpmagsförskjutning :

Ten cows suffering from displacement of abomasum (DA) were treated with two different electrolytesolutions. The DA cows showed symptoms typical for the disease. Four out of 10 cows had a metabolic alkalosis and two a metabolic acidosis. The cows were mildly hypocalcemic, and 9 out of 10 were mildly to moderately hypokalemic. Six out of 10 cows showed muscle fasciculations.

Ny världsordning, nya utmaningar? En teorianvändande studie om förhållandet mellan USA och Europa sedan Kalla krigets slut

In this thesis I discuss and analyse the relationship between USA and Europe since the end of the Cold War. Many authors claimed that the Soviet threat was the glue that kept the continents together. Now that threat is gone and new challenges have risen. In what way has this relationship been influenced by the new challenges this new era stands for? By doing a case study and by using two quite different theorists, John Mearsheimer an offensive realist and Joseph Nye who is a liberal institutionalist, I?ll try to show how for example September 11, anti-amerikanism and NATO can be explained and understood.

UPPFATTNINGAR AV ETT NYTT RYSSLAND?V?RNKRAFT ELLER STRATEGISK TIMEOUT? Inverkan av Rysslandsuppfattning p? svensk-finsk nedrustning 1995?2009

This study investigates Swedish and Finnish official perception of Russia following the Cold War. This is aimed at categorizing changes in perception of Russia over time and assessing the impact of perception on defense policy. The study uses a comparative method where the contents of three foreign policy reports of Sweden and Finland respectively are analyzed according to dimensions based in image theory. Results show that Swedish and Finnish perceptions of Russia are overall similar between the reports being compared, except for Finnish perception of Russian relative power being significantly greater. Changes in Swedish and Finnish official perception do not clearly correlate with changes in defense policy.

Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Just war teorin och de nya krigen -en möjlig kombination?

In the political world of today the discussion of Just wars are very present, since the international law and the UN Charter provides certain rules about when it is justified to go to war (jus ad bellum) and how a justified war should be conducted (jus im bello). The discussion about jus ad bellum and jus im bello derives from the theory of Just war. Both in international law and the Just war theory, focus is on interstate wars were the actors are two sovereign states. Since the end of the Cold War there has however been a change in the way wars are conducted. From interstate to intrastate warfare, where the government in most cases no longer has the monopoly over the warfare.According to these facts, my conclusion is that the Just war theory has to expand and incorporate a focus on the human rights in order to be able to meet the new standards of the new wars.

Frisk med probiotika? -Skyddar eller lindrar ett dagligt intag av probiotika mot förkylning, feber och influensasymtom?

Bakgrund: I Sverige drabbas vuxna av i genomsnitt en till två förkylningar per år och barnminst dubbelt så ofta. Totalt betalade Försäkringskassan ut 4 656 667 vab-dagar (vård avbarn) under år 2010. Probiotiska bakterier i tarmen konkurrerar med sjukdomsframkallandeorganismer och reducerar dess förekomst i tarmfloran. Om probiotika kan användas för attminska eller åtminstone förkorta sjukdomstiden skulle det vara en enkel metod till en relativtlåg kostnad vilket sparar tid, pengar och lidande för alla parter.Syfte: Syftet med denna systematiska översiktsartikel var att undersöka huruvida ett dagligtintag av probiotika skulle kunna skydda mot eller lindra förkylning, feber ochinfluensasymtom.Sökväg: Litteratursökning i databaserna PubMed och Scopus har genomförts. Sökord somanvändes i olika kombinationer var: probiotics, effect, common cold, fever, flu, influenza,respiratory diseases, lactobacillus och bifidus.Urvalskriterier: Inklusionskriterier vid litteratursökningen var humanstudier i RCT-form därinterventionen varit dagligt bruk av probiotika.

World of Warcraft : En virtuellt social värld

In today?s modern society with high-speed connections covering the globe people are more than ever finding themselves gazing into the cold lights of the computer screen. On the other side a strange and exciting world yet to be explored awaits. Many are those who spend hour after hour running over green hills swimming in vast blue oceans in the lands of Azeroth, the playfield in the MMORPG game World of Warcraft.

Inneklimatundersökning : Hur fungerar ventilationssystemen i två större lokaler och hur ser kommunikationen kring detta ut mellan hyresgäster, hyresvärd och projektör?

This examination paper is a study of the indoor climate in a theatre and a practice room for orchestras placed in Sickla in Stockholm. The designer of the ventilation system wondered if he had managed too make a good environment for the users and he also wondered which of the rooms that had the most desirable climate. The project includes polls for visitors, interviews of people connected to the rooms and measurements of the physical environment. The results show a small dissatisfaction about the thermal indoor climate, it?s a little bit to cold and the air draws.

Induktiv provning av ferritiskt rostfritt stå

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

Utopia Trek : utopibegreppets resa genom Star Trek

Humanity has always dreamed about a better world. These dreams has manifested themselves in the vision of Utopia - the good place, but also the non-existing place. Up until World War II man still wrote optimistic descriptions of this ideal world, and spread the idea through literature. In the aftermath of the atomic bomb and under the influence of the cold war, these publications seized to surface in literary surroundings. Despite this utopia did not die - it has only changed.

EU:s gemensamma utrikes- och säkerhetspolitik - En studie om dess uppkomst och institutionella utformning

This thesis aims to explain the emergence of the Common Foreign and Security Policy of the European Union, and its institutional shaping, by using elements of Neofunctionalism and Liberal Intergovernmentalism.Using Neofunctionalism, the Common Foreign and Security Policy can be explained both as a side-effect of Europe's economic integration, and as a way to maintain the former and the European Union's position as an economic superpower. The institutional shaping is a result of lack of convergence between important national interests. Therefore it rests on a firm intergovernmental base, with rigorously limited use of supranational decision-making.For Liberal Intergovernmentalism, geopolitics and ideology, and to a certain level log-rolling, have played important roles. The reunification of Germany convinced France to form an alliance between the two countries. France, determined to achieve an economic and monetary union, thus offered Germany a political union, including a Common Foreign and Security Policy on intergovernmental terms.

OTEC-Ett energialternativ för enhållbar ö

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
