In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

We have ourselves met misunderstandings about the tasks of librarians. The general opinion is that librarians are positioned behind the charging desk or are putting books on shelves. Other tasks are invisible and unknown to the public. The aim for this study is to explore the tasks that a selection of Swedish librarians does. The questions we have answered are: what do the librarians themselves claim to work with, which competences are necessary for this job, what does our study show regarding the librarian as generalist or specialist and finally; can the tasks that we find in our study help to understand the conceptions profession and status in relation to librarians.

The application of the LSS law and how the public organization (Municipality of Hudiksvall) later had to reform their organization to fit the new demands is the foundation to this master's thesis. An internal evaluation was performed due to this reorganisation process within the social care department (LSS unit). The aim was to investigate and evaluate if the reorganization resulted in a better working environment and if the work load (distribution of work) became more evenly divided between the different unit managing directors. The primary empirical information to this master's thesis is collected from that evaluation report. The main aim of this master?s thesis is to answer if the organisational choice between specialised or de-specialised working tasks has an effect (experienced and measured) on the level of stress among the unit managing directors.

This study has focused on testing the following two hypotheses:? Pest resistant plants have higher levels and/or several different kinds of secondary metabolites. ? Induced defensive systems in resistant plants are activated more rapidly than those of susceptible plants. As a background for the test of the hypotheses a short literature study was performed concerning plant defensive mechanisms in Arabidopsis thaliana.

Under mina 10 veckor på Swiss har jag fått ta del av olika projekt som dom har jobbat med. Jag har fått arbeta med nästan alla steg i pipelinen när man framställer reklam för TV samt print. Eftersom jag inte har haft någon huvudsaklig uppgift under denna tid tänkte jag ta reda på hur det är att jobba som generalist för ett mindre företag som jobbar med effekter för reklam och hur det skulle vara att jobba inom ett stort företag som jobbar med långfilm..

A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants. In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.

Ungulates are causing conflicts between stakeholders due to browsing damage on forests and agricultural crops. At the same time there is a big demand of keeping high ungulate densities for sports hunting and recreational purposes. Movement patterns of ungulates are strongly correlated with forage availability. Therefore, measures affecting forage quantity and distribution might be a tool to reduce the economical losses in forestry without decreasing the ungulate densities and thereby decrease the conflict between different interest groups.This study investigated the potential biomass production and utilisation of marrow-stem kale (Brassica oleracea var. medullosa), at game fields in Misterhult, Sweden, as well as browsing effects on adjacent forests.

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

Examensarbetet har gått ut på att självständigt jobba som 3D-generalist och få kunskap och erfarenheter ute på arbetsmarknaden. Jag har jobbat i samarbete med ett TV-företag på en vinjett som kanske skulle användas. Det har varit ett hårt och stressigt arbete. Det har funnits saker som inte gått att slutföra, en deadline som överskridits. Det har funnits ändringar idémässigt samt osäkerhet.

Continuously grazed grasslands have remarkably high plant species diversity. In Sweden this type of habitat has declined for the last two centuries. Changed land use has caused habitat fragmentation and loss of habitat quality. This has caused a great number of plant species to end up on the verge of extinction. To try to save this unique habitat and the species that are tied to it, lots of resources are laid on restoration of abandoned grasslands. In this study, plant species richness of continuously grazed, abandoned and restored grasslands were related to degree of overgrowth, time since overgrowth started and rate of overgrowth.

Herbivore impact on the Swedish forest has under a long time been a common subject of debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).

AbstractA beautiful death ? Manliness in four Japanese samurai moviesThis thesis deals with the samurai and his portrayal in Japanese historic movies and what kind of messages he conveys in form of masculinity to theater audiences. Four movies were chosen, two from the 1960s and two from the 2010s. The reasoning behind this was to look at two eras of samurai movies and if possible try to see differences between them. The history of the samurai, being a man and woman in modern Japan, R.W Connell and famous Japanese authors from different time eras acted as tools to try to answer the questions in hand.

Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties. The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.

Utifrån tidigare forskning om och utvärderingar av musikämnets ställning i lärarutbildningen är syftet med förestående uppsats att ytterligare belysa musikämnets situation i den svenska lärarutbildningen såsom den manifesterar sig i kursplanerna på högskolor och universitet. Föremål för analys är samtliga lärarutbildningars kursplaner i det allmänna utbildningsområdet (AUO), som tillsammans med den nationella kursplanen i musik (Kp2000) utgör underlag för besvarandet av forskningsfrågan ?På vilket sätt förbereds lärarstudenter för musikundervisning enligt Kp2000??. Ur ett hermeneutiskt perspektiv genomförs analysen baserad på fyra sökord; ?Musik?, ?Estetik?, ?Musisk? samt ?Konstnärlig?, ord hämtade ur den presenterade kontexten kring analysobjekten.

The aim of this study was to examine how newly qualified social workers from Linnaeus University in Kalmar feel that the school has prepared them with the professional skills to meet the demands that exist within social work. Social work education is a generalist training that will result in a professional qualification. With a qualitative approach eight newly qualified social workers were interviewed.We used the sociology of knowledge as an overall theoretical approach. We also used experience- based knowledge as a theoretical approach. One of the study's conclusion was that the graduates had difficulty linking theory to practice.
