Forsmark 3 ?Ett Framtida Biobränslekraftverk?
Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.
The importance of Yeheb (Cordeauxia edulis) for Somali livestock production and its effects on body tissues when fed to Swedish domestic goats
This master thesis was conducted in order to investigate the effects of the browsing
species Yeheb on animal tissues in Swedish landrace goats and to make a literature
review in order to increase the knowledge of the importance of this plant for livestock
production in Somalia. The evergreen Yeheb bush is a very important feeding source for
grazing and browsing animals in Somalia during the dry period. Yeheb contains
cordeauxiaquinone that stains the bones of the animals red/pink, which has been an
increasing problem when exporting meat to foreign countries. In an experiment, two
goats were fed dry and fresh leaves from the Yeheb bush for one and two months,
respectively. The goats did not feed the intended amount of dry leaves, since the supply
and palatability was not as high as estimated.
Den föränderliga samtidshistorien : En analys av historieläroböckernas beskrivning av orsakerna till Jugoslavienkriget 1991-1995 och Kosovokriget 1998-1999
AbstractThe purpose of this essay is to investigate the views Swedish elementary school teachers produce on the subject of ethics. The teachers? thoughts on selection among ethical notions is described and also how these notions are assessed. The essay proceeds from the central content and the knowledge requirement in the syllabus of religious knowledge.The empirical survey is based on qualitative scientific interviews with four teachers employed in grades 4-6 at different schools.The teachers find ethics in its current state of the syllabus hard to define and they find encounters with parents and pupils difficult in their tasks. The selection of ethics is decided by previously planned basic values education or from conflicts erupting during schools hours.
Bedömning och betygsättning i bildämnet : En kvalitativ studie av elevers och lärares syn på bedömning och betygsättning i bildämnet
The purpose of this paper is to try to understand which negative effects grading and judging in art class can have on the students. The emphasise lies on how the media specific parts of the subject is affected. The goal is to get knowledge how students experience getting judged and graded and how this affects them, hence understanding which factors affects them in a positive or negative way in this process. The literature study starts with a historical survey of the swedish grading system and the art subject in Swedish schools. It countinues to explain the current curriculum with an emphasise on art.
Goat production in Laos and the potential of using Erythrina variegata as a feedstuff
Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.
Den digitala skuggan : En studie om mediekritik och unga mediekonsumenter i ett digitalt nyhetslandskap
The purpose of this study is to examine young peoples' perception of their media criticial competence in relation to digital news. The study is based on quantitative research interviews with young people (15-17 years) and qualitative interviews with people in the same age group as well as teachers and international media professionals.This study's theoretical point of departure is McQuail´s observation that peoples' values and views to a great extent are influenced by the media. Another source of theoretical inspiration was Haberman's ideas about how a diversity of views and arguments increase the citizens' ability to reflect critically on social developments - maybe even more so than in societies with independent media and "neutral" news.The study shows that the young generation of web based news consumers assumes that it is very important to be an aware and critical consumer but also that they do not feel sufficiently equipped with the right tools required to understand the long-term impact and effect of the media reporting online. Young people basically seemed to acquire their knowledge about media by doing and learning on their own. Surprisingly, according to the young people that were interviewed for this project, the schools seemed to play a secondary role in the development of their media critical capacity.
Några biblioteksanvändares syn på bibliotekariers kunskap: En kvalitativ studie av uppfattningar vid ett folkbibliotek
The purpose of this Master?s thesis is to investigate how public library users consider the knowledge of the librarians and to examine what the users expect from the librarians. To begin with, we contemplate our own view of the librarians, their knowledge and what help we expect at the library. Realising that we do not expect particularly much from librarians, although we have studied to become librarians for two years, we assume that the regular library user does not expect much either. This assumption resulted in our decision to investigate this particular question.
Sjuksköterskors kunskap om och attityder till undernärng
ABSTRACTBackground and aims: Nutrition is a part of the medical treatment, and also a part of the nursingcare. In spite of this, malnutrition is a common problem in the health care sector. Studies show thatnurses have too little knowledge about nutrition and malnutrition and that nutrition has low priorityin the daily work. The aim with this study was to find out the nurses self-reported knowledge aboutand their attitudes towards malnutrition, nutrition screening, prevention and treatment of patientswith malnutrition.Methods: A questionnaire was handed out to 65 nurses in two different care units and 36questionnaires were answered.Results: The respondents from the two care units self-reported their knowledge about nutrition andmalnutrition low. Most of the respondents stated to have a big need of education about nutritionscreening and more than half of the respondents stated that they have a need of education forprevention and treatment of malnutrition.
Urea som kvävekälla till växande ungnöt
The purpose of this study was to examine whether urea could be an option as a nitrogen source for young cattle, the study was limited to risks related to feeding, growth and feed efficiency. Microbes in ruminants have the ability to convert nitrogen to protein, this has been highlighted by beef producers as they are in search of cheap protein feed resources. Urea can be a worthy source of nitrogen for growing young animals, because of its high nitrogen content and the low price. Studies have shown that the replacement of a portion of the total protein content by urea in diets with low content of crude protein, like corn silage, may improve animal growth and feed efficiency. Replacement of all the true protein with urea can result in reduced feed intake and microbial growth.
" ...köra lite på intuition" - Sjuksköterskors attityder och kunskaper om intimt partnervåld - en empirisk studie.
Intimate partner violence (IPV) affects both men and women, in homo- as well as heterosexual relationships. The most recognized form of IPV is violence against women. The proposition "Kvinnofrid" was approved by the Swedish parliament in 1998 and proposed an extensive effort to increase knowledge and awareness of IPV among occupational groups, mainly in the health care system. These professionals are also often directly involved in the care of victims of IPV. The main purpose of this study was to investigate attitudes and level of knowledge among nurses about violence in an intimate relationship.
Mer kreativitet med fler patent? En textanalys av förslaget till nytt EU-direktiv Patenterbarhet för datorrelaterade uppfinningar och anslutande dokument.
In February 2002 the European commission put forward a proposal for a new directive on The patentability of computer-implemented inventions, but which during my work on this essay has not been decided on yet. The directive has divided the decision-makers in the union, the commission and parliament, into two different positions regarding by which range computer-implemented inventions should be patentable. The parliament has amended the commissions proposal in a substantial way and the legal process has caused a heated debate both within the unions administration and among various interest groups both in favour of and against a patent on computer-implemented inventions. The loudest protests have come from a group that feels threatened by a possible software patent: Open Source. In this study I examine both the arguments by the decision-makers and by the lobbying for and against the proposal.
Att se sig själv som en del i ett större perspektiv : En analys av skolämnet historia i Lgr 69, Lgr 80 och Lpo 94.
In this essay, I intent to examine history as a school subject in Swedish compulsory school (for children aged 7-16), it contains mostly an analysis of the syllabus for history in the three latest curriculums Lgr 69, Lgr 80 and Lpo 94. The main purpose of the essay is to illuminate the development and the change history as a subject has gone through during this specific time, and my will is also to illustrate the view on knowledge and learning that is revealed in the syllabus for history in today?s curriculum (Lpo 94).The survey shows that in Swedish compulsory school, history as a subject has changed significantly. During the examined years, the contents have been exceptionally broadened and that has lead to increasing demands on the students as it has gone from being directed to the individual and its contiguous history with shorter outlooks on the rest of the world, to requiring the individual to be able to see and understand other parts of the world and different time, on the basis of it?s own history and culture.
Produktivitet vid stubblyftning :
Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.
Förväntad och upplevd kunskap : En enkätstudie bland elever på Hotell- och Restaurangprogrammet
The purpose with my study was primarily to illuminate the students' expectations on gained knowledge during their studies at the upper secondary school Hotel- and Restaurant program, and to what extent these expectations were fulfilled. Secondarily, the purpose was to compare the students' expected and perceived knowledge with the program goals set by the Swedish government and the knowledge requirements expressed in a pilot study made by the Education council of the Hotel and restaurant business (UHR, 2007).I chose a quantative approach and I used an anonymous group enquiry among students at the Hotel- and Restaurant program at two different upper secondary schools to carry out my study.Tendencies in the result suggested that the students at the Hotel- and Restaurant program expected high knowledge level within the competence areas of Guest reception and communication, Cleaning and hygiene, Cooking of cold and hot dishes and Waiting. The expectations were not big within the areas Computers and Internet and Business economics and management.Fulfillment of expected knowledge tended to be high within the areas where the expectations were big. It might therefore be a good investment for schools to work on the student expectations to increase motivation within the low expectation areas.A confrontation of the tendencies in the result with the program goals and the competence requirements expressed in the UHR study, suggested that the upper secondary Hotel- and Restaurant education might focus some more the areas of Guest reception and communication, Beverages and Organization of banquets. Business economics and management should be given much more weight..
Vanans makt : Betydelsen av vana i praktiska verksamheter i naturen
AbstractOur life-experiences and our background form the way we act and the activities we are involved in. The overall purpose in this thesis has been to study what habits are to be found in different activities related to the outdoors and how these habits have been developed. Hopefully this work can contribute to a better understanding of the meaning of habits in our lives and thereby play a part in a further differentiated talk about habits and knowledge in society. The background and my theoretical approach has been three views of habits:In practice these patterns of habits are not separable so this approach should be seen as a way of making the development of habits clearer. Another purpose is to study how the following concepts can be related to habits: Reflection, master-apprentice, episte?me, techne, phronesis, interest and tacit knowledge.
