Certain microbial residents from composts are known to possess the ability to suppress soilborne plant pathogens. Trichoderma spp. and Gliocladium spp. are commonly found in composts and are perhaps the most wellknown hyperparasites of fungal pathogens, which may also be naturally present in compost. Trials have many times proven them to be effective against plant diseases caused by soilborne pathogens such as Pythium spp., Phytophthora spp.

The purpose of this essay was to examine how professional social workers work with follow up foster home placements. The study was based on qualitative interviews with ten professional social workers from different municipalities in Skåne in an attempt to answer the following questions:* What routines exist for the follow-up work with foster care?* What factors have an impact on how the follow-up is formed in the particular case?* How can the follow-up affect outcomes of the placement?* In what way could the work with follow-up foster home placements develop?The theories we chose to analyze our material from was the ecology of human development formed by Urie Bronfenbrenner and the theory of civil courage formed by Lennart Lundquist. The interviews were semi-structural which gave the respondents a chance to talk in a free way about the questions we presented.The result of the study showed that there is a difference in the way social workers form the follow-up work of foster care. The greatest difference is in whom the social workers include in their follow-up.

We started out the study with a preconception of culture as something that creates difference between groups of people, which had been verified by our prior research. We also had a sense of culture as a polysemous term. Our assumption is also that there is an opinion within social work practice that Swedish social workers are faced with a cultural barrier when encountering immigrant clients.In this study our aim is to examine constructions of the terms cultural competence and culture. Constructions of the terms ethnicity and ethnic diversity are also observed, although the main reason for this is to show what relation these terms have to the terms cultural competence and culture, and how they may give each other meaning, according to the theory of social construction. In addition to constructions, we also aim to bring out discourses around the terms, upon which we will create a discussion about power and dominance informed by post-colonial theory and critical discourse analysis (CDA).

Abstract The purpose of this work is to investigate children?s perception of Swedish birds. Through qualitative questions there were twelve children interviewed. I showed the pictures for the children of different animals that we discussed but with focus on birds. The children could partly distinguish which of the pictures that represented birds and who did not.

The thesis examines how sex/gender and sexuality are represented through text and images within the Internet community Sylvia whose primary target group is girls. Through an examination of the aesthetics, the member rules and the choices that constitute the framework for the site, the study observes Sylvia as a cultural context. In relation to this setting, the ten most visited member profiles at the time for the study are more closely examined. These profiles are studied from a constructivist view of sex/gender and are analysed from the perspective of feminist and quee r theory as well as in the light of feministic debates concerning sexuality and erotica. The thesis shows how Internet as a forum and the non-heterosexual context Sylvia open up for a constructivist understanding of sex/gender and also leads to a questioning of "masculinity" and "femininity".

Sweden signed, in 1992, the Convention on Biological diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).

In the directive 2008/104/EC on Temporary agency work there is a regulation concerning that there shouldn?t be any restrictions or prohibitions in national legislation if it can not be attributed to the public interest. According to that the purpose of this paper is to investigate whether the Swedish law about reemployment in 25 § LAS is a restriction for temporary work agencies, it?s role on the labor market and also to investigate what consequences a restriction can have from a diversity perspective. To fulfill the purpose I have been using a legal dogmatic method based on determination of the current law.I have by the legal research determined that reemployment is not a restriction for temporary work agencies.

The aim of this dissertation is the production of a landscape management document to protect and improve elements of biological, cultural and economic value found within the site at Tosthult. The study involves both analysis of the current grazing regime, comparison of today?s flora with flora collected in the fifties and a SWOT analysis of inhabitants? views on Tosthult?s landscape and neighbourhood. The resultant landscape management document applies to an area over 134 ha and is valid for thirty years. The proposal contains 26 separate management units, each with necessary information on the area, definition of management goals and the mix of management procedures to undertake.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

This work of examination describes an environmentally oriented product development aimed to develop new packaging with improved environmental and sale aspects of the products from Primus Sweden AB. The report covers the design process from the first collection of facts to the final results with a description of all methods involved in the work. The focus has been on a clear environmental awareness and the report contains a deepening of the concept life cycle assessment (LCA) for product development. In the process, the consumers? opinions of the brand Primus and environmental profiling formed the basis for the packaging to communicate the right values such as quality, technology, environmental awareness and adventurer?s first choice.The deepening of the life cycle analysis shows that composting and other alternative treatment of the biological cycle is not possible to implement in a satisfactory way in the design process.The work results in two final concepts.

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).
