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.
Lyssna, Tala, Tänka. Övningsteknik ? en huvudfråga?
This thesis is about practising on a different level to get an insight to what techniques might work for me as a double bass player. It is about discovering how to use your brain into playing at your best level. I practised both talking and singing to myself and read a lot about thinking and hearing not only the music but every note before playing. The thesis idea came from not having a technique that worked for me while practising alone. I wondered why it is such a difference between what we do at the lessons and what I do when practising by myself..
Chewing behaviour of growing cattle
Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.
"Än en fågel, än en blomma" : En tematisk och dialogisk studie av ungmör och skaldinnor i Anna Maria Lenngrens dikter.
Anna Maria Lenngren (1754-1817) is known as one of Stockholms Posten?s sharpest satirists. Over the years many literature researchers have based their analysis and interpretations on biographical facts. This means that we miss important parts of her authorship, as she almost exceptionally has been writing role-poems. In a role-poem, the author takes a role as a fictitious narrative subject and/or another poem character.
Om Eyvind Johnsons Stad i ljus
This is a study of Eyvind Johnson?s novel Stad i ljus from 1928, first published in French as Lettre recommandée, 1927. The purpose has been to prove that motives, themes and narrative techniques characteristic to Johnson?s later writings is present as early as in this novel from the twenties. In the novel as well as in the contemporary short stories Johnson starts to explore the symbiosis between living, traveling and writing and begins to use metafictionality as a method to approach autobiographical material.
Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon
Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques.
The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.
Social behaviour and time budget of breeding bulls
The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.
Om att lära sig prestera under press
I have researched different methods for practicing with the purpose of learning some useful ways to handle my performance anxiety issues, to better understand the phenomenon, and to be able to perform better under pressure. I chose or created nine methods and used each during a decided period of time, each period ending with a performance. Afterwards I analyzed the methods with the help of audio recordings and written concert evaluations to see if it was possible to alter my practicing techniques to be more directly focused on preparing for the concert situation..
Drama & vägledning : Metoder som speglar livet
This study illustrates how drama methods and career counselling might interact. The aim is to investigate whether drama methods can enhance career counselling methods. Drama is here defined as an umbrella term that includes all forms of action methods used in psychology and education.A literature survey was carried out in parallel with qualitative research interviews. Three professional drama leaders were interviewed separately. This was followed by a group interview with five upper secondary school students, who had all taken a course in drama with a focus on personal development.The findings show that there are common and consistent goals and values between drama and career counselling.

Skolutveckling och ledarskap, Specialpedagogisk påbyggnadsutbildning, Lärarutbildningen, Malmö högskola
Syftet med följande studie är att undersöka vilka kompensatoriska hjälpmedel som specialpedagoger arbetar med i grundskolan i årskurserna F-9. De kompensatoriska stödåtgärder vi vill undersöka är de som är inriktade på inlärningsstil, minnesträning och studieteknik. Vi vill med detta examens arbete belysa och beskriva en del av alla de hjälpmedel och metoder som finns för att underlätta skoltiden för elever i svårigheter av olika slag.
Vi har genom en kvalitativ forskningsintervju byggt upp ett samspel mellan två personer, respondenten och intervjuaren.
Studiens resultat visar att många specialpedagoger är väldigt kreativa och engagerade i arbetet med att förbättra elevernas studieteknik och minne.
En studie om möjligheter att stoppa förfalskningar : Spårbarheten i en global värld
The purpose of this study is to describe the traceability of products that protect against counterfeiting and examine how protection against counterfeit products have been developed to date, and to display the opportunity to streamline the protection of products and brands.Nowadays, in the global world, it is getting increasingly more difficult to track the products. Especially for the last link in the chain, which in most cases is the customer and who is constantly exposed to risks. This report deals with the possibilities of preventing and detecting counterfeit products. Fake products are not unusual in an historical perspective. It has been common with counterfeits ever since the Middle Ages continuously until today. Forgers have become more skillful and they are successful in most industries. Many of the fake products are of poor quality and can be downright dangerous to the customer.To answer the question, the author used a qualitative collection method.
Chalmersmodellens applicering på starkt överkonsoliderad lera
In this master?s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi?s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead.
Vibrationsbaserad maskinaktivitetssensor
I detta projekt undersöker vi om man kan bygga en maskinaktivitetssensor medhjälp av en enkretsdator som genom en accelerometer mäter en maskinsvibrationer. Sensorn skall generera en statussignal. Accelerometern ger enmätbar signal baserad på maskinens vibrationer. Enkretsdatorn används för attsampla, transformera och analysera signalen och generera statusinformation.Med LabView kan vi spara, studera och analysera olika signaler och olikatransformer. Vi studerar maskinvibrationer i LabView och beslutar att 5 kHzsampling räcker för att fånga intressanta vibrationer.
Effektmätning i pump
The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.
