Miljöeffekter av alternativa system för behandling av hushållsavfall i Santiago, Chile : en jämförelse mellan deponering och förbränning med energiutvinning

This report was written by Lisa Bengtson and Hanna Paradis and describes the degree thesis "Environmental impacts of solid waste treatment in the Metropolitan Region, Santiago, Chile ? a comparison between current system and incineration with energy recovery". The purpose of this thesis was to investigate if incineration with energy recovery could be motivated through an environmental perspective as an alternative to landfilling of solid waste in Santiago, Chile. The study was performed with Life Cycle Analysis as a theoretical base. In Santiago, situated in the thirteenth region of Chile, Región Metropolitana, lives 6,5 million inhabitants. The major part of the solid waste produced in the region is landfilled on three different sanitary controlled landfills situated outside the city center.

Analys av planering inom byggproduktion. Hur kan förbättring ske med hjälp av slututvärdering och återkoppling?

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter

In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).

Kemisk karaktärisering samt nedbrytning av process- och avloppsvatten vid SCA Ortvikens pappersbruk

During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

Värdering av tillgångar : En branschpraxis för klädbranschen och byggbranschen

The valuation of an asset is one of the most important thing with accounting, though one of the most difficult thing as well. However, in deciding useful service life for an intangible asset and property, plant and equipment, there are quite a margin for the companies, which creates a difference between companies and industries. When computing the value of the inventories there are a few possibilities available for the companies, which also can generate differencesbetween companies and industries. Although these differences can occur, there might be some similarities in the companies? estimates.

Genusaspekter på föräldraledighet i svenska små och medelstora företag

The main intention with this study was to explore how parents, employed in three Swedish small- and medium-sized companies, experienced their combination of work and parental leave. The investigation was carried out by a questionnaire, and the 21 participants estimated the attitude from and the treatment by mainly the management and the colleagues. The answers were analyzed both from a perspective of gender and in the aspect of high- and low utilizers of parental leave. The results showed that although both men and women generally estimated the attitude from the management and the colleagues towards parental leave to be positive, the parental leave was divided traditionally and unequally between the parents..

?Tänd ett ljus?? : Klientens upplevelse av Marte meo behandling.

The purpose with this study was to investigate the client?s experience of Marte meo treatment and the procedure in the treatment from a responses and relational perspective, since the treatment occur within the social service frame. The theoretical framework consists of some central concepts. The concepts are experience of treatment, responses and relational perspective. The analysis of the empirical material has been carried out with the help of the concepts and earlier research.The method consisted of qualitative, semi-structured interviews with six informants.

Koldioxidsutsläppsbesparing vid biogasproduktion

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

Vård på behandlingshem : -manipulation eller frigörelse?

In this study have I examined how treatment of girls with neuropsychological impairments is functioning? I have looked at the theories and methods of treatment on the base of the care program and how it is put into practice. In addition I have interviewed four girls who have undergone the treatment program.To gain perspective on institutional care as a social phenomenon, I have tried to give a brief historical retrospect in which particular care for women are described. I am also affecting certain gender aspects of institutional care. I have also tried to make a brief account of current research on the treatment.The study is a qualitative study in which I am apart from literature studies used participant observation in depth interviews as a method.My results indicate that a well structured treatment with CBT approach can work well to achieve lasting behavioural changes in students..

?Rent kaos och ren lycka? : ? Några flickors beskrivningar av att ha genomgått behandling för självskadebeteende

The main purpose of this thesis was to take part of girl?s descriptions and experiences of their treatment for deliberate self-harm and to investigate whether they still experience effects of the treatment today. Our main research questions where; how do the girls describe their experiences of the treatment method, do the girls describe that they still experience any effects of the treatment, and finally how do the girls look back on their treatment today? In order to answer these questions, we carried out eight qualitative telephone interviews with girls that had undergone treatment in a specific treatment centre. We chose to analyze the material from the salutogenic theory and the concepts of SOC (sense of coherence) and with a hermeneutic approach.

Uppgradering av biogas med aska från trädbränslen

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

KBT-gruppbehandling av bipolär sjukdom : En pilotstudie

Bipolar disorder is a chronic affective disorder, characterized by episodes of mania and depression. Previous studies have shown beneficial results for CBT in conjunction with pharmacotherapy over pharmacological treatment alone. The aim of the present study was to evaluate a CBT treatment in group for patients with bipolar disorder, run by Norrlands universitetssjukhus. The treatment group consisted of pharmacologically stabilized patients (n=12) who received group CBT. They were compared to a control group (n=5) who received pharmacological treatment only.
