Askåterföring i Jämtland : biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi
Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.
FEM?modeller för expansionsanalys av piplines
REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, afinite element modelling and analysis tool. In an expansion analysis the pipeline is modelledwith thin?walled pipe elements called PIPE20 which allows plastic deformation. However, ina recent analysis the results retrieved from the PIPE20 element were incorrect for strainsabout 1 percent. One main issue was that the PIPE20 element overestimated the strains.The purpose with this Master Thesis was to become familiar with the theories and analysismethods used in pipeline design.
Timeliness cost for agricultural sprayers : weed control in cereal crops
Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.
Muntlig formativ kamratbedömning som kommunikativ praktik : En designbaserad studie i det naturvetenskapliga klassrummet
In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.
Gestaltning och förverkligande av Icehotels utemiljö säsongen 2009/2010
This paper constitutes graduate work at the landscape
architecture program at the Department of Urban
and Rural Development at the Swedish University of
Agricultural Sciences, Uppsala. The main purpose of this
paper is to create a project from an idea to reality. The
place for the project is the environment of Icehotel in
Jukkasjärvi in the north of Sweden. Icehotel is a unique
hotel concept and each winter a hotel, a church and a
bar is built at the area of only ice and snow, and each
spring it all melts down and returns to the Torne river.
During the project a plan for the environment, in ice and
snow, will be made and then a part of it will be built in
January 2010. The purpose is to improve the outdoor
environment with landscape architecture to enhance the
experience of Icehotel and create an exciting entrance to
the area.
Hur uppfattas pcSKOG AB och pcSKOG-gård av privata skogsägare? : en undersökning av en programvara för privatskogsbruket
pcSKOG-gård is a computerised manager plan for private forest owners, developed by the
pcSKOG AB. The program is based on forest stand data, joined with a map of the forest and
GIS-applications. The purpose is to offer a program for private forest owners managing the
forest and with the possibility of updating the actual status of the forest.
The company pcSKOG AB is the leading producer of programs for forest management and
has developed the program since 1997. The program is currently the most common program
used by private forest owners in Sweden.
The aim of this thesis, leading to MSc in forestry, is to investigate the purpose of the private forest owners when purchasing the pcSKOG-gård. The thesis also studies how private forest owners use the program, what they use it for and how the private forest owners state that the program has achieved to fulfil their expectations.
The thesis is also a market research concerning the knowledge and attitudes the private forest owners have about the program and associated services.
The study material has been collected during two phases.
Grafisk skärpa : ett arbete om gaturummet
The streetscape is a complex environment with a lot of different parts and users.
If you look at the streetscapes main parts you have floor, walls, roof and
furniture. The floor in the streetscape, the street, consists of the ground and the
paving. It can be made of a lot of different materials with both architectonic
and practical functions. The walls usually consist of the houses. They have a big
influence on the streetscape depending on architecture, heights and widths.
Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Kvalitetssäkring av hushållsnära avloppsfraktioner : vad kräver livsmedelsbranschen?
On-site sewage systems are common on the countryside of Sweden with approximately one million on-site systems installed. Due to insufficient function, these contribute significantly to the total discharge of phosphorus to rivers and lakes, causing eutrophication.
In order to reduce eutrophication and to fulfil one of the environmental quality objectives, the decision was taken by the Swedish Government in 2005 that 60 % of phosphorous in sewage sludge is to be recycled to arable land before 2015. To make recycling a reality, new solutions have to be found. Federation of Swedish Farmers (LRF) takes an active interest in this issue and has initiated this study.
One problem is that the food industry is sceptical towards recirculation due to the risks that products from sewage systems may contain pathogens, heavy metals and unwanted chemical compounds, e.g.
Litteraturförmedling på gymnasienivå : En studie av kanon, beskrivningar och litteratursyn i fyra läromedelspaket för gymnasieskolan
This study examines in which way literature is presented in four schoolbooks for the Swedish senior high school of today, compared to descriptions and selections in Swedish universities. The study covers two basic schoolbook categories used in the teaching of Swedish and comparative literature: anthologies and textbooks.The four anthologies structures and their joined canon are presented, and the text canon of 12 common writers is studied and compared to the corresponding text canon in the universities selection of texts to main courses in comparative literature. The four textbooks are analysed by close reading of the presentations of four different writers and their works, where the textbooks for the Swedish senior high school are viewed through the glass of literary guides used in Swedish universities.The study also analyses what literary perspective is present in the Swedish school principles for education in literature and display, through earlier didactic studies, a sketch of the classroom reality of education in literature.The study finds that the examined schoolbooks for the Swedish senior high school tend to, not only shorten the text length and amount of texts but also, simplify the selection and presentation of the writers production. This leads to certain fixed and, in some cases, almost stereotyped ?roles? that are assigned to the writers and limits their production.
Hur arbetar och resonerar några lärare kring bedömning och hur är detta relaterat till deras syn på olika måltyper?
Syftet med detta arbete har främst varit att lära oss mer om bedömning. Vi har uppmärksammat bedömningens avgörande roll för elevers kunskapsinlärning och intervjuat några lärare om vad de har för uppfattning om bedömning. Fokus har lagts på resonemanget kring relationen mellan de-ras syn på bedömning och olika måltyper. I resultatet redogör vi för de olika lärarnas resonemang kring målen, bedömningssätt och bedöm-ningssituationer. Vi har även uppmärksammat att vissa lärare har en intuitiv kunskap om vad ele-verna kan och detta problematiserar vi i diskussionen, men har även redogjort för, de av oss in-tervjuade lärarnas resonemang kring detta.
Bland smuts och andligt förfall : Svenska Missionsförbundets Kina kring sekelskiftet 1900
The purpose with this thesis is to analyse the image of the Chinese that was constructed and maintained in the materials published in association to the Swedish Mission Covenant Church (SMF) missionary work in China between the years of 1890 to 1914.The analysed material is mainly from the periodical Missionsförbundet, the analyse also include various books, biographies and anthologies. Inspired by Michel Foucault I found my methodological starting point in his discourse term. Frome there, by the help of the texts of Torjer A. Olsen, I constructed a discourse analyses, by which I analysed my materials.The survey showed that the material associated to SMF foremost constructed a negative pictureof the Chinese as unclean, conservative, arrogant, liars, greedy, loud, bad singers and that the woman situation was seen as untenable. A more appreciative picture also emerged and the Chinese was described as polite and strong.
Varför väljer elever det estetiska programmets musikinriktning? : En studie över musikestetelevers tankar kring sitt gymnasieval
During the spring of 2013 we developed a visual identity for Jönköping Bandy, a bandy association in Jönköping, which was founded in 1947.Jönköping Bandy?s main problem was the low interest for the association by the local people. The association also had problems with the economy, which made it hard for them to merchandise themselves.In Jönköping, there were a lot of sport associations, and therefore, it was difficult to find sponsors. One way to help the association, was to create a good visual identity for them. A visual identity that would reflect on the proper values of the association.The intention was: ?Through graphical design, we want to convey Jönköping Bandy to a larger amount of people, and get increased knowledge in graphical idiom.? and was torn apart into these three questions:What core values does Jönköping Bandy have, and how can we convey them through the visual identity?Which visual materials does Jönköping Bandy need?How do other teams in Allsvenskan Södra merchandise themselves through their websites?The work began with a study of relevant theoretical literature, with focus on graphical design.

Djurförbud : en analys av domar enligt 29 § Djurskyddslagen samt definition av resurs- och funktionskrav
The aim of this study is to with the help of my data, conduct statistic analyses about animal welfare mistakes and scarities, as a preventive measure for the public sector point of view and how farmers handle their animals in these cases, when and how these mistakes and scarities are likely to appear and in this way perhaps manage the existing problems. The aim of using judicial decisions of banning ownership and caretaking of animals according to the 29 § is that this judicial decision is the outermost fortification of animal welfare.
In November 1938 the pro tempore investigator handed over a report with a proposition according the animal welfare legislation. Pro tempore proposed that the court should in some cases, be able to order a person guilty of cruelty against animals to a ban of owning or taking care of animals. This proposal unfortunately was turned down. The question about introduce a ban against owning or taking care of animals into the Swedish animal welfare legislation was again discussed in April 1967 at an interpellation debate in the parliaments second chamber.
