Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore some sort of treatment of the sludge is recommended before use.

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.

This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block experiment, with two blocks comprising 12 vases containing 1 L water and two tomato plantlets, treatment in which, nutrient solution was based on Vortex-treated water was compared with an control using untreated water. All vases were kept in a static aerated culture system in a daylight chamber for four weeks. The results showed that the effect of the two blocks exceeded the effect of vortex treatment in terms of leaf area and weight of fresh and dry matter. Plant height, stem width and internodal length were significantly different in tomato plants grown in Vortex-processed water compared with the untreated control.

Most descriptions of stereotypic behaviours have in common that these repetitive behaviours only has been observed in captive animals and therefore it has been proposed that stereotypies exist because we house animals in environments that are sub-optimal to them. Some scientists claim that performance of stereotypies in itself decreases the animal's welfare due to costs in time, energy and health and a poorer quality of life. Other scientists assert that individuals performing stereotypies may have a better welfare compared to the rest of the animals in the same environment, since these individuals have developed strategies to cope with stress. Studies have estimated the prevalence of abnormal behaviours in horses to 18-30 % of the population. Several studies on cribbing have revealed a prevalence of 4-5 %, although some results indicate that more than 10 % of the horse population performs this stereotypy.

The purpose of this essay is to describe how probation service officers regard their professional role and their liberty of action within the motivational treatment program, MIK, and the probation organization. To answer the purpose three questions were formulated: 1) Does the probation service organization affect the individual discretion for the probation service officers, and in that case how? 2) Does the motivational treatment program, MIK, influence the probation officers? professionalism and their professional role? 3) What advantages and disadvantages do the probation service officers consider MIK being related to? The method conducted in the study was interviews with five probation service officers in Stockholm. The interviews were combined with a theoretical framework based on themes as organization, professional role, professionalism and motivation. The result showed that probation officers consider themselves to have a relatively high discretion within their work.

In the collections of the Vasa Museum, 100 leather objects have exhibited salt precipitations. The objects, that have previously been impregnated with PEG, have become deteriorated and fragmented due to the precipitations. During a previously conducted study it was established that the precipitations consisted of iron and sulphur. However, it was not established whether they occurred in the leather?s inner structure and no treatment plan was developed.

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Aim: The aim is to create a review that examines different forms of massage therapy and their effects on hypertension.Method: Literature review of 10 scientific articles on the subject of massage and its effects on blood pressure. The literature searches were made with PubMed and Cinahl using the keywords "massage therapy", "effects" and "blood pressure".Results: The articles showed that massage had a positive effect in lowering blood pressure. This could be explained by greater extent of relaxation in the participants investigated and an increased activity of parasympaticus and reduced secretion of stress hormones. The articles do not agree on what form of massage therapy is most effective in lowering blood pressure and it is uncertain for how long the effect can remain.Conclusion: Massage is usually seen as a treatment without scientific basis. There is evidence that suggests that massage therapy is an effective treatment for lowering blood pressure.

Background: Atopic eczema has increased in the last decade among children. The nurse can have a major role to prevent the disease. Aim: the aim of this study as to describe the nurses´ work in primary care with prevention to families with atopi with focus on atopic eczema among children. Method: A literature review based on analysis of fifteen scientific articles was done. Results: If the child was breastfed both positive and negative effects were evident.

During the last ten years the cultivation of maize in Sweden has increased and is expected to grow further. Most of the maize in Sweden becomes silage which is used to feed animals at farms. Maize has in other countries been shown to be a substrate for growth of mould and especially Aspergillus spp., Fusarium spp. and Pencillium spp. has been reported.

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Although Sweden is considered to be one of the world?s most equal countries, studies show that social work to a large extent is characterised of stereotype conceptions about men and women. This implies that clients with addiction problems are treated by there gender belongings and not from there individual needs. The purpose of this qualitative study was to examine how aware the social services are regarding gender perspectives and equal opportunities among male and female addicts. The social workers that were interviewed had different opinions about what extent the gender perspective had in the treatment of the clients.

The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.
