In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

The aim of this study is to analyse how female neopagan practitioners form their identitiesindividually as well as collectively. Using Ernesto Laclau?s and Chantal Mouffe?s discourse theory and Anthony Giddens? descriptions of late modernity and self-identity, I intend toinvestigate my informants? construction and upholding of a meaningful identity and sense ofself. I will also look at how the neopagan movement can be viewed as a phenomenon closely interwoven with the overriding tendencies in our contemporary society. Neopaganism is an umbrella term that is used to describe a number of modern nature religions that take their inspiration from pre-Christian traditions.

The importance of chemical use is enormous for areas such as agriculture, industry and medicine and hence a prerequisite for our modern society. In order to protect humans and the environment from the negative effects of chemical use, chemical regulations have been used at a relatively early stage in our history. The purpose of REACH, the new chemical regulation of the European Union, is to generate new knowledge of chemicals within the European market and to increase the responsibilities of the enterprises when it comes to risk management. Whether the enterprises will implement the regulations or not will be of vital importance for the realization of the law?s intentions.The purpose of this study was to identify possibilities and problems that can occur when a downstream-user SME is about to implement REACH.

Many perceive a boom in nostalgia and what is retro, especially within the marketing discipline. This thesis studies how nostalgia functions in the advertising context and aims to shed light on which effects there are from nostalgia evoking communication, what connections there are with other important factors as well as aspires to develop the understanding of the underlying psychological aspects and the emotional bonds to events (as nostalgia evoking stimuli in the thesis), which pave the ground for nostalgic emotions. Point of origin has been classical measures of communication effects and models of connections and causality and to these important factors have been added. Results show clear connections and correlations between nostalgia and positive communication effects, even with control for other factors that may interfere. However, the results show that some factors have moderating effects that should be important to take into consideration, namely how well the brand and the event in the ad are perceived to fit the advertising context.

Although textbooks are scientifically proven that they are important and central to the school curriculum one should think critically about the content in textbooks - is it really compatible with the curriculum of following the textbook tradition? As a teacher there are different ways to reflect on which textbook to choose. It is important to compare several textbooks with each other and be aware that a textbook should follow the curriculum. A teacher examines many sections/topics in the textbooks, but in this paper only one section will be reviewed among four different textbooks. The section to be compared, in the paper, is the interwar period.

Syftet med denna uppsats är att få en inblick i pedagogers syn på inskolning. Vi ville ta reda på hur pedagogerna praktiserar sina kunskaper och erfarenheter för att barnen ska få en trygg och positiv start när de börjar skolan. Att ta reda på föräldrarnas uppfattning av inskolning är också en del av syftet i och med att de spelar en viktig roll i inskolningsprocessen. Undersökningsmetoden som vi använde oss av är en empirisk studie. Resultatet bygger på intervjuer med sex pedagoger och insamlade enkäter från 76 föräldrar.

Denna uppsats är en pilotstudie för Regionförbundet Östsam. Den syftar till att kritisera och testa en metod som behandlar serviceutbudet i tätorter inom Fjärde storstadsregionen. Denna metod bygger på att kartlägga utbudet, vikta detta enligt en poängmodell och sedan analysera resultatet och söka skapa en ortsklassificering. Metoden är tänkt vara ett verktyg i modern regionalplanering och kunna förbättra serviceutbudet i regionen. I studien har svensk regionalpolitiskt historia, centralorts- och nätverksteori använts för att visa på hur modern regionalplanering söker skapa samarbeten utifrån funktionella omland och inte genom administrativa områden.Det studien visar är att metoden står i förhållande till den politik som förs av dess användare.

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Med en stor central hall på över fyra våningar skiljer sig byggnaden från det klassiska konstmuseet. Rummet ger med sina vita betongväggar och massiva skala inte bara plats åt konsten, utan förstärker den också. Det diffusa ljuset från takfönstret ger en sakral stämning och hallen kan hålla allt från en enskild tavla till enorma statyer, men också filmvisningar och teater. Samtidigt finns möjligheter till mer traditionella utställningar i de mindre omgivande hallarna. I övrigt finns möjlighet till föreläsningar och undervisning i anslutning till entrén och shoppen.     Byggnaden är också mer än bara en konsthall för Uppsala och årummet.

This essay investigates how the chapters of the interwar and the Second World War have changed in the high school history textbooks during the period from 1944 to 2008. In the study eleven history textbooks have been studied, most quantitatively but also qualitatively. For example the number of pages and rows devoted to different subjects and countries are compared in the books over time. The result of the study shows that there are some big changes over time but in most sections there are also big differences between the books, which make it harder to draw general conclusions. There are a lot more names, pictures and dates in the newer books compared to the older ones, although the number of different names is about the same in all the books.

The object of this paper is concerned with the subject youth and politics. The aim of the paper is to study what influence our today modern societies has between two social landscapes, Greece and Sweden and try to give an explanation to why young peoples political engagement is different in the two countries. To fulfil my aim of this paper I have used a few questions, these questions will give me an insight in how young people look at politics, what their interests are and if they feel that they can and ought to act political. The theoretical starting points I?ve used I?ve chosen with reflection to look at the social landscape we live in and its changes over time.

I denna uppsats har jag jämfört mottagandet i dagspressen av Agnes von Krusenstjernas roman Kvinnogatan och Karin Boyes roman Astarte. Syftet med uppsatsen var att analysera och jämföra hur två romaner av författarinnor som är kända för sina moderna och progressiva verk togs emot av en framförallt manlig kritikerkår. För att kunna göra det använde jag två teorier. Den ena är utformad av Gunilla Domellöf och tittar på hur kritiker, framförallt manliga, i allmänhet tog emot kvinnliga författare under det tidiga 1930-talet. Den andra, utformad av Tomas Forser, utgår istället från kritikern och handlar om kritikerns uppgift.

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

To perform a historical record of Beijers Park's development to date is about securing the tracks back in time. The historical record about the park tells not only the history of the park but the city, district, local residents and art of gardening. As the historical story is documented the necessary base for establishment of any care plans in the future and the base for cultural and historical value the park is made. Beijers park can in such work be treated alone or as part of the context of parks that were built during the same era in Malmö's history.Beijers park origin from the era of the late 1800s, when the entire green structure in Malmö changed. The park area today covers 12 hectares and is located in the district Kirseberg.
