Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

This essay puts its focus on examining vendors? underlying decision criterias when choosing an estate agent at the purpose of selling an apartment.

The great debate topic in media and among real estate agents in spring 2011 wasspecially reduced prices. Specially reduced prices means that a property is advertised at a considerably lower price than the evaluated current market value of the property. This is to attract more bidders in a potential bidding. It is in this case not completely established by law what is meant by considerably lower price, why this concept is difficult to interpret. Real estate agents got lot of criticism due to the output prices which were too low compared to the final prices.

This research intends to study the media's representation of unaccompanied refugee children on the basis that the media has a power in the construction of society. The focus is on whether children's vulnerability and needs are presented in the media and whether the children?s voices are heard. It is also of interest to study the agents that speak in the media concerning unaccompanied refugee children. The study is based on a theory that social reality is a construction of interaction between individuals and groups.

The CASA-paradigm, Computers Are Social Actors, was introduced in the book "TheMedia Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have used a virtual agentin order to find out if we are polite to the agents, or still to the computer. Two experimental setups was conducted. The two setups had a common first part that was carried out on onecomputer with one agent.

Adolescence is more and more characterized by messages containing allusions and attitudes through social agents (family, friends, school and media). Therefore the purpose of this study was to investigate what significance the social agents and their messages, concerning sexuality, have in relation to young people's thoughts, questions and socialisation.The study is made from the young people's perspective. Our target group was 15 to 16-year-olds in ninth grade at a compulsory school in Sweden. The quantitative part of the study consisted of an anonymous and voluntary questionnaire among the students. To achieve a greater variety we made an interview as a complementary addition in which nine students participated.We found our main theoretical starting point in Anthony Giddens's theories about social agents, modernity, post modernity and sexuality.The conclusion was that the young people in our study foremost associated sexuality to sex, love, relationships and sexual orientation.

Digitala läromedel blir ett vanligare inslag i skolgången då ny teknologi erbjuder tidigare okända pedagogiska möjligheter. Denna uppsats undersöker hur elever som använder ett digitalt läromedel i form av en virtuell lärmiljö för matematiklärande upplever denna lärmiljö. Dessutom undersöks elevernas prestation i lärmiljöns matematiska uppgifter. Skillnader mellan elever i olika årskurser samt elever som är matematiskt låg- eller högpresterande studeras. Matematisk prestation beskrivs utifrån Goods (1981) passivitetsmodell som innebär att lågpresterande elever är mindre risktagande i klassrumsmiljön.Elevernas upplevelse av digitala läromedel studerades i en virtuell lärmiljö bestående av två moduler, en spelmodul och en modul för skriven dialog.

Services, no matter if they are established on the market or not, are often problematic since they are difficult to define for the customer.

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

This essay reviews the situation for real estate agencies within the Stockholm area. In this essay we assume that costumer loyalty is a requirement for survival on the competitive estate market. Two actors have been compared; A well known national Internet-based agency, Skandia Mäklarna, and a smaller local traditional agent Mäklarfirman Grönberg. These actors have been analyzed up on theories on loyalty, relationship marketing, service marketing, quality and involvement .The conclusion of the essay is that it is possible for small estate agencies to compeed with larger Internet based agencies by building loyal relationships with their customers. This can be achieved if the right strategic decisions are made.

We are working on the development and design of an approach to agents that can reason, react to the environment and are able to update their own knowledge as a result of new incoming information. In the resulting framework, rational, reactive agents can dynamically change their own knowledge bases as well as their own goals. An agent can make observations, learn new facts and new rules from the environment, and then update its knowledge accordingly. The knowledge base of an agent and its updating mechanism has been implemented in Logic Programming. The agent?s framework is implemented in Java.

The number of new estate agent offices is increasing yearly and each year many hundred new estate agents graduate. The comparing of estate agents by sellers has perhaps been most common in larger cities, but as competition has increased even in smaller towns we experience that it has become a common phenomenon even there. We both come from a small town but are not afraid of the idea of moving to a larger city as newly qualified estate agents. We ask ourselves, which are the determining factors in the choice of a estate agent in a large city as opposed to a small town? Can we see any differences? The purpose with this essay is to give us added knowledge about which factors private persons consider to be important in their choice of an estate agent when selling a house.The body of information is based on two parallel surveys, one in Hudiksvall and one in Stockholm, together with interviews of people in this line of business.

Today?s schools agrees that there are students that are in need of special help in school, but how this help best connects to the students can the schools not agree about.That?s why I in this essay have chosen to look closer at four different compulsory schools and they?re teaching of students requiring special help. I choose to look at two community schools and two open schools.The aim with this essay is to see if the teaching of students in need of special help is different or the same on the four schools. One of the theories that I have used is Haug´s theory about segregated and included integration.In my essay I have used qualitative research interview. I have interviewed one person from each school management.The result shows that it is not the way the schools teach the students that is important, instead the schools see the contacts between families and the school and the personals attitude agents the students as the most important factor when they work with this students..

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.
