Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields
The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.
Solar energy on Swedish pig farms : a sunny story?
In Sweden there is a large interest in renewable energy but the market for solar power is still small compared to other countries such as Germany. Here many farmers produce their own electricity. The Federation of Swedish farmers have acknowledged the potential for Swedish farmer to produce electricity and there is an interest among the farmers. The agricultural branches in Sweden most suitable for solar power are pig production and poultry due to the even electricity need throughout a year. Swedish pig farmers are going through a period of unsteady profitability which makes it interesting to see whether producing their own electricity can affect the economic situation.
Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).
Initial evaluation of the Meritas Troponin I test for measurement of equine cardiac troponin I
Cardiac troponin I (cTnI) is considered a specific and a sensitive biomarker of cardiac disease, and due to a high inter-species sequence homology; human cTnI assays can often be used in veterinary medicine. The main aim of this study was to perform an initial evaluation of a human cTnI test, the Meritas Troponin I test, for measurement of equine plasma cTnI, in order to investigate whether the test could be a possible subject for a more comprehensive validation. The hypothesis was that the test could measure equine cTnI, as there is a good homology between equine cTnI and human cTnI.
The evaluation included a dilution parallelism, an intra-assay precision study and measurement of plasma cTnI healthy horses. In the dilution parallelism and the intra-assay precision study, equine plasma with previously established high cTnI concentration, according to another cTnI assay, was used. In addition, cTnI concentration was measured in plasma, collected from 19 horses, without signs of disease at physical and ECG examinations.
The obtained curve in the dilution parallelism was linear, indicating that the Meritas Troponin I test can be used to measure different concentrations of equine cTnI in plasma.
Spatiella mönster och lager av organiskt klor och klorid i barrskogsjord i sydöstra Sverige
The concentration and storage of organic chlorine and chloride were determined in soil, to a depth of 40 cm, in a coniferous forest in the Stubbetorp catchment area in south-east Sweden. Also, the spatial distribution of the two forms of chlorine was determined. Soil samples were collected at 49 of the nodes in a grid with approximately 105 m between the nodes. The analysis of spatial variability suggested that no spatial autocorrelation was present either within the variable organic chlorine or chloride. This means that no sample was more influenced by another nearby sample, as compared to other samples further away.
Det kulturella arvet- en resurs i omsorgen av de äldre
The essay depicts the opposite views of the director and an actor during the filming of a specific scene in a feature film. The actor feels that he is not being listened to. This leads to unforeseen consequences for the director, as the actor no longer wishes to take part in the marketing of the film prior to its opening night. Everything is seen from the director?s point of view, she is working in a film world dominated by men.Questions are being asked if the director?s instructions are clear enough or if the actor, fearing getting lost, is mixing up his own feelings with those of the character he is portraying? What happens to the collaboration and how does it affect the rest of the team and the completion of the production? The director is also the producer.
Utveckling och visualiseringav arbetet med ständiga förbättringar : För Pfizer, Strängnäs
Today it becomes more and more important to work with continuous improvements to stay ahead of the competitors. Pfizer in Strängsäs started working with continuous improvements in 2010. By the end of 2012, the company?s goal is to reach 24 improvements per employee at the factory.Their project has two main purposes; to examine the need and possibilities for visualization regarding continuous improvements at the production department and to develop a concept for visualisation of the entire factory?s continuous improvements.To attain the information required to examine the needs at the production department, interviews with relevant employees at the department were conducted. Using interviews as a benchmarking instrument was also helpful in getting different points of views.
De blir fria i tanken : En kvalitativ studie om pedagogers tankar om pedagogisk dokumentation
This MA thesis analyzes how the protagonists and the narrative structure relates to ?the Child? as a linguistic/cultural construction in Mare Kandre?s early authorship (1984-1991). A thematic of children portraits defines this period of Kandre?s writing, which consits of the following works: In a Different Country (1984), The Annunciation (1986), Bübin?s Kid (1987), The Burning Tree (1988) and Aliide, Aliide (1991).Linguistic components, such as the word ?child?, the name ?Kid? and a reconstruction of the concept of childhood, holds an actuate position in these narratives when they first appear in direct relation to the protagonists. This suggests how generally accepted categories and concepts consciously are at work in Kandre?s writings.
Fine-Mapping of Equine Multiple Congenital Ocular Anomalies on horse chromosome 6
Multiple Congenital Ocular Anomalities (MCOA) is a genetic disease that affects primarily Silver coloured horses of breeds such as the Rocky and Kentucky mountain horses. In these breeds the Silver dapple colour is very popular leading to an increase of affected horses. The major feature of the disease is ocular cysts of variable size. Large cysts also lead to a variety of secondary syndromes, for example retinal detachment. In previous studies the locus for MCOA has been mapped to an interval of 420 kb on equine chromosome six.

Samband mellan luftföroreningar och klimatfaktorer - en statistisk unersökning
That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.
Elektromyografisk aktivitet och power i en knäböj : en explorativ studie
Syfte Syftet med föreliggande studie var att studera korrelationen mellan EMG-respons och effektutveckling i samband med genomförande av knäböj.MetodFyra manliga testpersoner deltog genom att utföra både knäböj 90° och djupa knäböj i en Smith-maskin som är ansluten till en Linear Encoder som möjliggör beräkning av effektutveckling. Samtidigt registrerades elektromyografisk aktivitet i musklerna Vastus lateralis, Hamstrings och Gluteus maximus. De utförde knäböj på olika relativa belastningsnivåer; 20, 40, 60, 80, 100% av 1RM.ResultatResultaten visade inte en stark korrelation mellan medel-EMG och power, inte heller mellan medel-EMG och hastighet, dock indikerade resultaten mellan de sistnämnda en tendens till att en lägre EMG aktivitet uppstod vid de högre hastigheterna. En starkare korrelation kunde antydas mellan medel-EMG och belastning/kraft. Ingen tydlig skillnad mellan musklerna påträffades i förhållande till resultaten ovan.
