Svampar associerade med raps : betydelse för uppkomst och grödetablering
Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems.
This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens.
The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.
Jakten på stoff : Hur historieläraren på grundskolenivå gör sitt stoffurval
No matter what subject or which grade you are active in, the teachers in Sweden have incommon that they are provided with governing documents that states the guidelines and goalsregarding each subject. Along with these governing documents every teacher has to findmaterial that will be used as the foundation of the teaching. This thesis is a study of howSwedish history teachers define what material they are going to use in their teaching, andwhich the factors are that is affecting these choices. The question whether a child?s ethnicaland cultural background is a factor that affects this choice of material is concerned, as well aswhat is current in Sweden and the world.
Hiv/Aids : Vad rör det mig ?
Over 40 miljon people in the world suffer from hiv/aids today. Africa is the continent that is worst affected by hiv/aids but how is the situation in Sweden? Why is it so quiet concerning hiv/aids in Sweden? Our aim with this work was to find out about the hiv/aids situation in Sweden and particulary in Malmö. The result of our research was that hiv/aids have increased since the year 2000 and most of the people had caught the infection in other countries than Sweden. This raised our curiosity concerning how immigrants/refugees are being treated when they arrive in Malmö and what are being done to stop hiv/aids from spreading further.We became very disappointed when we realised how little that is actually being done and how poorly the collaboration between the institutions are working.
Neutralitet med förhinder : En undersökning i hur bilden av Sveriges neutralitetspolitik under andra världskriget har förändrats i läroböcker i historia
Sweden?s role during the Second World War has been a matter that has been under much debate since the war?s end in 1945. The debate has however ebbed and flowed and established a discourse that Sweden was forced to give in to German demands and did so to avoid conflict that would have severely damaged Sweden. However, in 1991 a Swedish journalist Maria-Pia Boëthius published a book known as Heder och Samvete in which she explained that the Swedish concessions to Germany during the war were made out of profit rather than giving in to German demands. This sparked a debate that ended with the establishment that Sweden compromised and even broke its neutrality in favor to gain profit from the war.
Kompetens och ansvar kring hbt och homofobi i skolan : Intervjustudie med lärare i årskurs 7-9
Many reports infer that questions of HBT and homophobia are either poorly addressed or not addressed at all in schools today. This study is based on interviews with teachers of students aged 13 to 15. It is an inquiry to the teacher's thoughts about, knowledge of, and sense of responsibility to inform students of the subjects 'Queer', 'HBT', and 'Homophobia'. Who is responsible for educating the students regarding these subjects and what do teachers think about including these subjects in their curriculum? How do the teachers describe their knowledge of the subjects? Do they require further knowledge themselves in order to educate others in a proper way? The study is grounded in queer theories.
Timing i sångundervisningen
Since my experience is that teachers in singing hardly ever talk about when to sing a tone, I have chosen to examine this fact through interviews and earlier research in this matter. The interviewed singing teachers belong to different genres (classical music, pop/rock, jazz and folk music). I asked them to share their thoughts about the word timing, when it comes to music. I also wanted to know if they have any methods when it comes to teaching students to improve their timing. Further on, I have been discussing the results and the literature in order to make clear in what way singing teachers give priority to when a tone is being sung.
Exosomes as a potential mechanism of intercellular spread of prion protein
Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.
Validation of realtime-PCR of Fusarium avenaceum for detection in wheat
Mould is a common contamination in cereals. The growth of mould can stimulate mycotoxins production andsome of which at critical concentrations cause health problems in humans and animals. Fusarium is one of thefungus species that has been found in crops and can cause major problems for farmers such as reduced harvestand economic losses. A group of Fusarium species, Fusarium avenaceum, Fusarium poae and Fusariumtricinctum express a mycotoxin, enniatin. The limited information available today about enniatin-forming fungiis that they grow out on fields of wheat in colder climates.
Medborgardialog : Ett demokratiexperiment i Örebro kommun
AbstractIn the beginning of 2007 the Swedish municipality Örebro decided to have a democraticexperiment, which ought to go under the name, ?Dialouge for the citizens?. Therepresentative elected politicians in Örebro tried to find ways to involve the people in theprocess of ruling. Why they choose to try this experiment on this very delicate matter, theclosure of several schools in the municipal, is one of the questions this essay is trying toanswer.The purpose of this essay is to find out whether the process was an attempt for the politiciansof the representative democracy to implement deliberative democracy in the structure of thelocal governance.The result of this study is that the politicians didn?t manage to reach to the citizens the waythey formerly had planned..
Hygienisering av torkat bioavfall
The main project Dry preservation of food waste from households includes a new technique concerning drying and storage of dried biowaste as well as a study of the sorting of household waste and further usage of the dried biowaste. A question asked in the project is, can the dried biowaste be used as a soil amendment? If organic waste is used as a soil amendment, precaution concerning hygienic safety risks has to be accounted for. The objective of this M. Sc.
Användning av accelerometrar för detektering av rörelse i Husqvarna ABs gräsklippare Automower
In order to detect movements and vibrations on different appliance, especially robots and self-going devices are used different sensors. One of the most used movement sensors are accelerometers. They are three different types of accelerometers one-axes, two-axes and three-axes. They can be analogue or digital. Husqvarna AB uses an accelerometer to detect movements of their self-going lawnmower Automower.
Att uppnå varumärkesframgång genom dagens designtrender
The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.
Kvinnojourerna och myndighetssverige. Kvinnojourernas ställning i det svenska samhället.
The violence against women is an important matter. In Sweden there are several organisations that takes care of the women and children in need.One of the many organizations you can turn to is women's shelter organizations. They are nonprofit organizations. They depend on the contribution of peoples free time and on the government's awareness of the work that the organization do. The social services has the main responsibility to take care of women and children in need.
Alliansformation - relationen mellan Israel och USA
The special relationship between Israel and the US has been subject to questioning, and good many theories have tried to explain why it is so strong. The most common explanation is rooted in the school of realism, where strategy and national interest decide who one's ally is. This essay aspires to examine another possible reason for allianceformation; identity. Several books, which make for the theoretical backbone of this study, have been written on the subject of sharing beliefs, identifying with others and the consequences of this. The question being asked is whether Israel and the US actually share beliefs and, if so, which ones.
Utvärdering av labpilot - flödesbatteri : Experimentell studie
Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.
