This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Background: The need for structured practice has in recent years appeared in connection with the request for a more evidence-based nursing. In psychiatric care with its complex disabilities, it is important to have methods to identify these. Research has demonstrated the importance of patient participation in nursing that has been shown to affect their mental health. It is essential to get to know how patients with mental illness are capable of involvement in their life situation. The ICF emerged as a useful theoretical framework for development of questionnaires of patient participation.Aim: The aim of the present pilotstudy was to develop and test a questionnaire for participation, based on ICF.

Syftet med vår studie var att undersöka, analysera och diskutera lärarens, elevers och föräldrars medvetenhet och engagemang om elevernas progression inom läsinlärningen. Analys och slutsatser byggde vi på våra resultat och modern forskning om barns språkinlärning. Detta gjorde vi med hjälp av en klass bestående av 1 lärare, 19 elever och deras föräldrar. Vi använde oss av kartläggningsmetoderna God Läsutveckling och Ordkedjor, enkäter och intervju. Resultatet av vår studie visade att kartläggningsmetoden var betydelsefull, men metodvalet inte var det avgörande för läsutvecklingen hos eleverna.

The aims of the study were to investigate the prevalence and antibiotic resistance of Campylobacter jejuni and Campylobacter coli in chicken and chicken products, and to investigate farmer awareness of antibiotic resistance development. The study was conducted in the Can Tho province in Vietnam during six weeks in October to November 2008. Ninety-six samples from raw chickens were collected from twelve market places and analysed for the presence of Campylobacter. A total of 96 cloacal swabs from 20 farms were obtained and analysed for the presence of Campylobacter. Farmers were asked to answer eight questions concerning the housing of the chickens, modes of handling sick animals as well as use and knowledge of antibiotics and resistance development to antibiotics.

Additiv tillverkning (AT) eller 3D-utskrivning är en teknologi som har berömts den senaste tiden och förutsägs kommer att förändra hela tillverkningsindustrin.

Background: Energy drinks have been found in everyday-stores since 1997 and their popularity have increased over time. Consumtion of energy drinks takes place because of their ability to increase concentration and to decrease fatigue but also because of the popularity the drinks have got. Target groups for these stimulating beverages are adolescents and young adults. Energy drinks contain caffeine, taurine, glucuronolacton, carbohydrates and B-vitamins and voices have been raised about the eligibility for young people to ingest large quantities of these kinds of substances. Because of the properties of these substances it has become popular to mix energy drinks and alcoholic beverages to make up for the negative effects of alcohol and to be able to drink larger quantaties.Aim: The aim of this literature work was to investigate cognitive effects of the combination of caffeine in terms of energy drinks and alcohol and to determine if these effects could be harmful.Method: This literature work is based on five scientific articles retrieved from PubMed.

The purpose of this essay has been to answer the question of whether or not administrators of economic support perceive that their professional status is ranked lower than that of their coworkers in other fields of the social services.

We also wanted to determine in what way (if any) the comparative status manifests itself and what factors influences it.We?ve utilized method triangulation in order to answer the questions posed in our purpose. The quantitative study was conducted using a questionnaire and the qualitative with three interviews.

The present study is primarily of historiographical type, but also uses comparative method and qualitative text analysis. It mainly aims to explore how Germany and the issue of guilt have been portrayed in Swedish and German nonfiction literature (excluding teaching materials) during the years 1996-2010, in the context of the Holocaust, but also makes a comparison between these two countries' depictions. Furthermore, it also examines whether it is possible to link the various depictions to specific theories, in this case determinism together with the actor and structural perspectives, as well as to other potential factors such as the authors' personal connections to the Holocaust or the millennium. In addition, overall trends is an aspect which is examined. Despite the fact that the Holocaust has been the subject of extensive research, no study with the same selection as this one has been carried out before.

The issue of using citation based indicators in the evaluation of science is widely discussed. Only recently did bibliometric indicators become one out of many means for the allocation of financial resources for scientific research at Swedish universities. The purpose of this thesis is to discuss the issue of using citations when evaluating science. The author studied the issue from the perspective of citers? motives.

After having worked within the preschool and it?s system for a number of years, we have often reflected over the fact that many educators tend to look at children with language difficulties in several different ways, and many of them being conflicting. Something that might contribute to this problem is the fact that the term itself, language difficulties, is defined differently between individuals, who in turn affects the way educators and preschools deal with the problem.The aim of this study is to create an understanding of the problems related to language difficulties, and how it is being dealt with within the preschool environment. To achieve this we have chosen to work within a qualitative research approach, alongside a discourse analysis. The selection of informants we have chosen consists of ten, qualified educators.

The intention of this essay is to study the Swedish General Staff as a learning organisation during the period of 1914-1918 based on the theoretical work developed by the philosopher Bertil Rolf. Previous international research on the Prussian/German General Staff has shown that it is considered to be the first learning organisation in history. The Swedish General Staff was based on the German General Staff model and the focus of this study is to compare the development the tactics in Germany and Sweden regarding defence and attack in trench warfare. The questions are: How were the possibilities for gathering and analysing informa-tion affected by the war? Which conclusions were made for trench warfare in Swedish conditions? What experiences from the war and exercises in Swedish army were implemented in manuals and training?The conclusion of the study is that the Swedish General Staff was functioning as a learning organisation during the WWI through the ability to follow the international development, mainly in the Central Powers, and by modifying the experiences to the prevailing Swedish strategic and tactical conditions.
