Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

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.

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.

The Swedish Armed Forces is a public institution and consequently obliged to follow Swedish and international legislation. Thus, they are subjected to contrarious demands from different actors operating in its high-technological and high-institutional environment: to be a legitimate institution and at the same time operate with a high level of efficiency. This thesis is conducted with the aim of investigating whether The Swedish Armed Forces' steering document for gender equality is used to achieve visible and quantifiable results or if the document constitute a medium for reverberating legitimacy. To answer the research question, we applied a critical discourse analysis on the relevant documents and on the conducted semi-constructed interviews with members from different levels and positions in the organizational hierarchy. Subsequently, we came to the conclusion that the Swedish Armed Forces manage the demands for efficiency and legitimacy, which are forced upon them from the technological and institutional environment, by talking about them.

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.

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.

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.

The purpose of the project was to exam steams ability to sterilize carrots infected withLactobacillus plantarum. The project was a cowork with Brämhults Juice AB. They hadobserved an increase of Lactobacillus in the production of carrot juice during the summer. Tokeep the flavour of fresh fruits, the juice is treated carefully with heat. This means that thejuice only stays fresh for a few days, around two weeks for an unopened package and threedays for an opened package.In an attempt to remove the remaining Lactobacillus of the carrots, steam is tested as an extrastep in the production of juice.

This essay aims to investigate how students raised in Jehovah's Witnesses have experienced their career counseling during their middle and high school education. My main objectives are, based on the testimonies of former Jehovah's Witnesses, to investigate how career counselors can find a strategy to approach these students in a non-threatening way. I also try to take into account the contextual elements which are of great importance when counseling students raised as Jehovah's Witnesses. A qualitative study has been carried out with five informants with a background in the movement. The material has then been analyzed using a qualitative, narrative method.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

The concept of corporate social responsibility (CSR) has lately gained popularity throughout the globalized world. Swedish retail industry is no exception. Though increased levels of explicitly claimed responsibilities of companies, a number of other facts points out a development that contradicts this trend. Labour conditions and forms of employment is substantially retrograding, with an increased level of insecurity characterizing the Swedish retail labour market. At the same time, almost all Swedish retail companies explicitly state claims on social responsibility.
