Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Calculations of net present value are based on a discount rate, which requires knowledge about the company?s cost of debt. A common way to do this is by observing the company?s credit rating, when no credit rating is given it?s possible to use a synthetic rating model based on quantitative data to estimate a credit rating. Thus, the aim of this study is to increase the understanding of which quantitative data, in terms of key figures, that can be used to explain the given credit ratings for companies from the Nordic countries.In developing the model, key figures found significant in previous studies are being tested for whether or not they are applicable for companies from the Nordic countries.

Initiativet till projektet kommer från Nordic gyms ägare Christer Eriksson. Inför det första mötet mellan Christer och Jimmy Kärkkäinen, December 2010, var det egentligen ett annat projekt som var planerat att utföras. Då Christer med stor inlevelse berättade om deras nya produkt för bålträning och dess potential, kände båda parter att detta är det vi skall arbeta vidare med. En lång och spännande resa tog sin början.Nordic gym är ett helsvenskt företag som huvudsakligen utvecklar styrketräningsmaskiner. Nyligen har Nordic gym tagit fram ett nytt träningsredskap (Nidroc) för bålträning.

During the last decade millions of people have migrated to Europe. Parallel to this development, we see that many countries are becoming more hostile towards immigration. The success of radical right-wing parties (RHP) has been accredited to natives within the receiving countries turning to RHP to reduce their perceived threat from immigrants. Paradoxically, the RHP-support has also increased significantly among the immigrant population given the common assumption that immigrants are in solidarity with regards to shared experiences of immigration. In this dissertation, I argue for the importance of considering the increased RHP-support amongst immigrants, something that has been neglected in contemporary research.

Visby is a city that at first glance is of medieval origins. The popular image of scientists today is that the city was formed in the Middle Ages. According to some of the researchers Visby was formed during the Viking Age, it is based on the basis that the area has been used for a long period. Urban development in the Nordic countries is complex and there are different opinions as to why the Nordic cities emerge. It is important to shed light on the underlying process on why cities are emerging to provide clarity as to why Visby city is emerging.

This study uses European researcher Tomas Valasek?s hypothesis about factors required for defence cooperation in order to achieve conditions which can be successfully applied to the Nordic defence cooperation NORDEFCO. The study uses only Norway and Sweden on the grounds that they are the original actors and the driving forces behind the defence cooperation. The factors studied are; the countries' strategic culture, solidarity and trust between countries, similarity in military forces, if similar conditions prevail in the defence industry and if the intentions of cooperation have been clarified.Mainly government documents in the form of propositions, orientations and defence documents are studied, together with previous research in this area and, especially, interviews with representatives of NORDEFCO at military level and policy level as well as outside perspectives from the military attachés in each country. With the intention of studying the extent to which the factors Valasek features may prove to be significant in assessing the conditions for enhanced cooperation in NORDEFCO, the study raises the question of how it is possible to find expressions for the factors.

Charterflygbolaget TUIfly Nordic har haft problem med att utnyttja intervallerna på ett antal planerade underhållsåtgärder för deras Boeing 737-flotta fullt ut på grund av begränsningar i trafikprogrammet samt övriga praktiska begränsningar. De har även under en längre tid misstänkt att många intervaller för återkommande underhåll borde kunna eskaleras något för att möjliggöra en omläggning av trafikprogrammet och därmed effektivisera användningen av underhållsintervallen. Genomförs underhåll på flygplanen oftare än de behöver blir detta också en onödig resursförbrukare och kostnad för bolaget.Detta examensarbete har haft till uppgift att genomföra en granskning av de anmärkningar TUIfly Nordic haft på sin 737-flotta och gallra ut de anmärkningar som haft eller kunde ha haft någon relevans för någon av de underhållsuppgifter vars intervall TUIfly Nordic vill eskalera. Med denna information som underlag har sedan en bedömning gjorts om huruvida varje identifierad underhållsåtgärd är lämplig att utföra en eskalering på eller inte. Detta examensarbete har visat att en majoritet av de underhållsuppgifter som valdes ut för ändamålet anses vara möjliga att utföra den önskade eskaleringen på.

Sexual function in men with Spinal Cord Injury (SCI) is usually affected to a greater or lesser extent, depending on the type of injury and physiological prerequisites. Social contexts and psychological factors are other aspects that affect sexual function. Sexual dysfunction can lead to an impaired quality of life, depression and other illnesses. Aim: To study reported experiences of sexual function in men with SCI who have participated in The Nordic Spinal Injury Registry (NSCIR) five years follow-up. Design: Quantitative method consisting of a register study based on secondary data.

Bakgrund: Endast ett fåtal kvinnor i Sverige och övriga nordiska länder väljer en planerad hemförlossning. Organisationen för en planerad hemförlossning varierar mellan de nordiska länderna. Det är inte känt hur nöjda dessa kvinnor är med sin hemförlossning, det är därför av intresse att öka kunskapen om hur nöjda kvinnor i Sverige och Norden är med sin planerade hemförlossning.Syfte: Syftet med denna studie är att beskriva förekomsten av nöjdhet hos kvinnor som genomgått en planerad hemförlossning samt att jämföra förekomsten av nöjdhet hos kvinnor i Sverige med Danmark, Norge och Island.Metod: Studien är en retrospektiv tvärsnittsstudie med kvantitativ ansats. Materialet är insamlat 2010-2013 inom ramen för forskningsnätverket ?Nordic Homebirth? via en enkätformulär på internetsidan www.nordichomebirth.com.

Syftet med undersökningen är att åskådliggöra hur gymnasielärare i matematik samtycker några utvalda förändringar i gymnasiereformen Gy 2011, främst i förhållande till kursen Matematik 1.Vi har undersökt detta genom intervjuer med sex matematiklärare på sex olika gymnasieskolor i Uppsala. Tanken med undersökningen är inte att svara på frågan hur den svenska lärarkåren tänker kring dessa förändringar, utan att få fram en mängd olika åsikter och tankar för att belysa hur det kan se ut. Detta hoppas vi kan fungera som ett avstamp inför framtida forskning. Det framkommer i studien att lärarnas åsikter går isär både sinsemellan och mellan lärare och Skolverket och regeringen, men att man även samtycker på flera punkter bland de förändringar som gjorts i Gy 2011..

The aim of this paper is to illuminate and discuss the political and ideological aspects of Early Medieval Nordic music. Due to shortage of sources, this issue has been overlooked until now. Did Early Medieval Nordic music meet the requirements for political and ideological use? In what ways could music potentially be used politically and ideologically? Was music used as a political and ideological tool? This is examined by a contextual analysis combining music history and historical archaeology. The survey consists of a background account, focusing on the potential of music and some requests for political use, and three case studies, where musical reflections of societal tensions is investigated in folk music lyrics, Icelandic sagas and church art.

The main purpose of the study is to investigate Sweden's four large banks, concerningrisk and return, to see if there are any differences between them. The paper will alsoinvestigate the following sub sections: are there any differences in how the banks havesucceeded in managing geographically targeted funds and if there are any differencesin how funds are performing according to the fund size.The study is based on a quantitative method and has a deductive approach. Theselection consists of all of the four banks Swedish and Nordic funds (according tomorningstar.se 's categories "Sverige" and "Norden"). The study is based on secondarydata gathered from sources such as Morningstar, Affärsvärlden, Dagens Industri andthe Swedish National Banks websites.Swedbank Robur has performed the highest results in the case of Swedish funds.Handelsbanken has performed the highest results in the case of Nordic funds and thetotal of all funds that are in the study. Based on the results of the study it was possibleto distinguish a link between fund size and the annual return. .

I vår uppsats har vi tittat närmre på styrdokumenten för ämnet fysik i den svenska gymnasieskolan. Vi har jämfört innehåll och formuleringar mellan ämnesplan 2011 och kursplan 2000 för att lokalisera och analysera likheter och skillnader dem emellan. En närläsning av både styrdokumenten och didaktisk- och pedagogisk forskning gjorde denna jämförelse och analys möjlig. Vi som blivande pedagoger vill med detta arbete bidra med vår syn på styrdokumenten för fysikämnet i gymnasieskolan. Genom vårt arbete kom vi fram till att vetenskapsteori (Nature of Science) och samhällsfrågor (Socio-Scientific Issues) har fått en mer betydande roll än tidigare.

Energy is an important issue in the current world which significantly affects sustainability and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section which subsequently would be a ground to better management and maintaining a sustainable society. This study which is a bachelor?s project in sustainable energy, deals with estimation of CO2 emission from different types of residential houses in Sweden. An extensive literature review on energy use in Sweden by different residential sectors has been conducted.
