In this thesis a method for evaluating investments in small scale hydro power is presented. An analysis of the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented.Hydrolyzer is the name of the Excel tool developed to evaluate investments. The tool requests input data from the user and then evaluates the investment and generates a sensitivity analysis.

This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.

The aim of this thesis is to study the Swedish art field during the 1980s, from the perspective of the artistic production of Lars Nilsson. During this decade he became one of the most well known young artists associated with postmodernism.The thesis is divided into three parts, where the first part examines different influences and aspects of the art of Lars Nilsson, as well as the contexts he was a part of. This is performed through a chronological as well as a categorizing presentation, based upon different exhibitions where Nilsson participated during the 1980s.In the second part the subject is the Swedish art field, and how Lars Nilsson came to be part of a a new established category of a young generation of artists, mostly born in the 1950s, who were associated with youth, postmodernism and contemporaneousness. This part also puts attention to the importance of Lars Nittve, then art critic and curator, in introducing postmodernism, as well as establishing this new categorization of artists in Sweden.The last part of the thesis studies four different group exhibitions, and how they all exemplify how "a younger generation of artists" were to be connected with notions of postmodernism and contemporaneousness through curatorial practice. Lars Nilsson participated at the thirst three of these exhibitions.

Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.

The work presented here aims to give the owners ofChâteau du Grand Val, Roland and Marie Nilssond?Aubigné an integrated creative forest management planin which their goals with the property is heeded, andwhere the plan is so clear that they can follow it withoutmuch difficulty.This work has come about through the normal processesof forest management plans, landscape architecturalproposals as well as through field trips, field andliterature studies, and our combined experience fromour studies. The study visits, both on location in Brittany,France, but also in other places, as for instance Högestad,has provided the background information that formedthe basis of our analysis and the proposal that is derived thereof. Some suggestions, which we consider importantto the overall impression of the property, is provided amore focused and detailed solution, while other parts,which are important but can either benefit from havingdynamics in the design process or will be adapted toadjacent sites, are developed using a more generalapproach. In some cases several possible developmentprinciples are presented.The proposal presents a detailed plan for themanagement of the forest from the experience, wildlifeand forestry economic standpoint.

This exam paper has been a collaboration between the writers and System Anderson AB. The assignment was about completing a client application, running on a PDA, and a server application, running as a web service. The web service handles the communication with System Anderssons existing database. The main goal for the application is that it will be used to increase efficiency in storage management. The client application will hold functions for withdrawal, purchase, delivering and inventory.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

This report is the result of a project in the course Independent Projekt in Molecular Biotechnology at Uppsala University during the spring of 2014. The foremost purpose of the course is to give students the opportunity to carry through exstensive work in a project environment. This project was formed based on a comission from the biotechnology company SweTree Technologies, and the goal has been to compose a summary of the different techniques and methods that exist in the field of mass propagation of trees through the method of somatic embryogenesis.The project group has obtained information about the area mainly throgh reading patents, trying to find key components and bottlenecks in other companies? somatic embryogenesis technologies. This paper is divided into different sections, containing the patents of the automation of different steps in the process.

This final thesis is performed on commission of Hargs Bruk Ltd. Hargs Bruk manages one of Sweden?s largest privately owned forests. A main part of the managed forest is situated in Roslagen in eastern Uppland. Since 1934 felling calculations have been performed within the estate every tenth year.

Social fobi är en av de vanligaste ångestsjukdomarna. Rädsla och oro i sociala situationer och prestationsrelaterade dito är utmärkande för dessa individer. Social fobi tenderar, om den inte behandlas, att bli kronisk och det finns indikatorer på att tillståndet förvärras över tid. Idag finns behandlingar som ger goda utfall direkt efter avslut, men huruvida behandlingseffekterna håller i sig över längre tid är mer höljt i dunkel. Internetadministrerade självhjälpsbehandlingar har en möjlighet att öka tillgängligheten för denna klientgrupp och det är då av vikt att den är av god kvalitet.

Stress and burnout is a common healthproblem among different workcategories today. The aim of this study was to investigate possible presence of stress and burnout among radiographers and if there was a connection to number of years in the profession. Maslach Burnout Inventory was used as an instrument to investigate the possible presence of  burnout, supplemented with questions about stress. The instrument contained a total of 33 questions and was handed out to two hospitals in south of Sweden with a total of 51 respondents. The study showed that the most stressful situations arose due to workload, negative stress, bad working environment and high time pressure.

This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

This bachelor's thesis is an investigation into the public libraries'actions following the debate of Stina Wirséns character LillaHjärtat, featured in picture books and films for young children.The character was accused of being racist, due to its similarity tostereotypes such as pickaninnies. Because of this, the books'existence in public libraries was questioned.The purpose of this study is to investigate how librarians havedealt with these books, and what they have based their decisionson. To explore the background of these decisions we have usedPatrick Wilson's theory of cognitive authority (1983). We haveexamined which cognitive authorities have been used in thedecision-making process of how to handle the books containingLilla Hjärtat, and why these cognitive authorities have beenchosen. The method used in the study is qualitative interviewswith seven librarians working in public libraries throughoutSweden.The results of the interviews show that the librarians? mostprominent cognitive authorities have been authors and illustratorsof children's books.
