Behandlingsmetoder mot övervikt och fetma hos barn

Overweight and obesity among children and adolescents is increasing. Diseases which earlier occurred exclusively among adults are now also observed among children. There is an urgent need for new treatments that can change this negative trend. The aim of this study was to describe existing treatments for obesity among children in the age of 6-12 and the effect of those treatments. This descriptive literature study is based on 17 research articles published between 2000 and 2007 from different parts in the world.

Upplevelser av ätstörningsbehandling: en uppföljning av de långsiktiga effekterna av en dagvårdsbehandling.

The aim of this essay is to examine which help a group of women with eating disorders had from thier treatment in daycare in 2004. The aim is to examine how the women have experienced this treatment and how they live today. The central questions are: what was their life situation like before the treatment, what was their experience of the treatment, how could the treatment have been better and how are their lives today? The method is based on qualitative interviews with seven women who were all in the same treatment for eight weeks at Capio AnorexiCenter in Malmö. The women have also redone tests that were done right before and right after the treatment.

Bemötande och inflytande inom äldreomsorgen är ju bra, egentligen. : En kvalitativ studie om bemötande och inflytande ur ett brukarperspektiv

In this study we have investigated how care users in a nursing home experience their possibilities for influence and treatment from the staff. The study was conducted through focus group interviews with six participants who we met on four occasions. Questions the study departs from are: How do users experience their opportunity to influence? How do the users experience the treatment from the staff? The study has a qualitative approach and has been analyzed by means of symbolic interactionism, with an emphasis on the Self. Our results demonstrate that in situations of good treatment there is also a good influence.

Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten

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.

Optimalt ekologiskt : att gestalta praktfulla parker som kan skötas på ett hållbart sätt

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

Om anhöriga och relationers betydelse vid psykossjukdom i det psykoterapeutiska arbetet

The purpose of this study is to better understand patients suffering from psychotic illness along with their family members, and to identify treatment factors that have been helpful for these patients and their families by investigating how their relationships have been affected by treatment. In this way, treatment methods can be put in a theoretical context, treatment efforts can be clearer, and the therapist can develop professionally.The research method used is a semistruktureted interview conducted with tree patients and their families. One conclusion one can draw in the successful treatment with psychotic patients is strongly based on the therapist?s ability to build a safe and secure treatment alliance with both the patient and his family members. Meeting with patients in situations outside of the therapy room have been of great importance for the therapeutic process.Important themes for recovery that come forth during the interviews with the patients are the quality of the therapy session as healing factor.

Simulering av vindkraftverk och närliggande elnät vid Risholmen i Göteborg i SimPowerSystems

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

What works? : Grundläggande komponenter för ett positivt behandlingsutfall på institution med särskilt fokus på Kognitiv beteendeterapi (KBT) och dess tillämpning.

In Sweden there are many kinds of effort given youths with behavioral problems, one is institutional care. International research display a varying kind of results from this type of treatment. The aim of this study is to examine and illustrate which central components that results in positive treatment, but also starighten important components in KBT. On the basis of research results, important components for positive treatment have been illustrated as; the therapeutic relationship, the integrity of treatment, prosocial-contacts, positive climate in treatment, the continual of treatment, how to bring treatment to an end, the responsivity principle-the principle of need-the risk principle, learning and KBT.  Research also aims to investigate whether these components could be identified in the daily work of youth treatment on institution. This through a qualitative approach including six interviews held with staff working in treatment facilities.

Turbinkretspump system - Kraftvärmeverket i Borås

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

The study was based on a questionnaire that was made at the patient clinic. The questionnaire was conducted by the treating dental hygienist student after the treatment. The questionnaire was answered in the waiting room. Collection of the material occurred during the month of March in 2009.

Miljöanpsassad metod för hjultvätt

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

Björkbarksextrakt, BBE : en lönsam lösning på betningsproblematiken?

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

Ekosystemstödjande och multifunktionella växtval i urban miljö : En fallstudie med utgångspunkt i Nacka stadsbildning

This study has investigated how urban vegetation can be used in a multifunctional way to support ecosystem services in urban environments. Nacka municipality is in the start-up phase of building what is to become Nacka city. This provides a unique possibility to study and analyse what role the vegetation play in making the city a healthy living environment and how it needs to be adapted in order to be resilient against changing climate conditions and how the effects of those changes can be regulated. The study further investigates how airborne pollution, caused by urbanization processes, can be regulated or reduced by vegetation or species selection. Methods used in this study were a combination of qualitative interviews and literature studies, seeking to answer the questions: Which specific ecosystem functions are needed in the urban environment and which aspects will influence the ecosystems ability to deliver the functions in demand? And which plant species have the right mechanisms needed to deliver those functions? These questions have been studied and analysed in a local based context where the local conditions ands site specific needs of Nacka define criteria for plant selection.

Energieffektiva maskinval : Hjälpmedel för projektering av pumpar och blåsmaskiner till avloppsreningsverk

Idag fokuserar företag mer och mer på att energieffektivisera sina verksamheter då det finns både ekonomiska och miljömässiga vinster i detta. För att minska energiförbrukningen i samhället är det bra att börja med dess infrastruktur. För att funktionen hos ett avloppsreningsverk ska vara god samtidigt som energikostnaderna hålls nere är bland annat valet av rätt pumpar och blåsmaskiner för den aktuella driftsituationen av största vikt. Att hitta balansen mellan funktion och energieffektivitet hos en kombination av maskiner är dock ett tidskrävande arbete. Genom två fallstudier och matematisk modellering var syftet med detta examensarbete att bestämma huruvida det är möjligt att grovt uppskatta livscykelkostnaden hos olika kombinationer av pumpar och blåsmaskiner i varierande driftsituationer.
