Solvärme för en skola i Lerum. Studier av olika systemalternativ.
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Anaerob psykrofil behandling av hushållsavloppsvatten i UASB : Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten
Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
Mentaliseringsbaserad behandling av patienter med borderline personlighetsstörning : Infallsvinklar från patientgrupp och behandlare

The patients in the survey group were interviewed before and after treatment with regard to specific symptoms of borderline personality disorder and symptoms of other personality disorders with the semi structured interviews ZAN-BPD and SCID-II. Open interview questions that were worked up in a qualitative manner were as well put to the patients that had received the treatment program. A focus group interview with the staff working with the concept within the frame of the MBT-team of Psychiatry southwest in Stockholm was also carried out. The result shows on a group level between the pre and post measuring a reduction of specific borderline symptoms like impulsivity and cognitive symptoms.
Återinläggning av patienter 80 år och äldre på medicin- och kirurgklinik
ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method: Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine. Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.

The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.
Effektivare elanvändning på avfallskraftvärmeverk : Förslag till handlingsplan för minskad elanvändning på Renovas anläggning i Göteborg
This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.
Kan behandling av insomni förbättra komorbid ångest och depression?
This study investigated the efficacy of a multicomponent cognitive?behavioral intervention of insomnia, CBT-I, for patients suffering from an anxiety disorder and/or a major depressive episode together with comorbid insomnia. In particular, the aim of the study was to evaluate whether anxiety and depressive symptoms declined as a function oftreatment for insomnia. After rigorous diagnostic procedures, 8 patients were treated in a multiple baseline design. Patients experienced clinically significant reductions in insomnia-, (57 %) depressive- (75 %) and anxiety symptoms (40 %).
What happens during breakdown and repair of the suspensory ligament and what are different treatments aimed at?
Injuries to the suspensory ligament represent a huge problem in equine veterinary medicine. As many of the affected horses are elite-competition athletes, there are high expectations on veterinarians to make these horses fully functional again. The suspensory ligament has several features which makes the healing process complicated. So far no treatment has shown to optimize the healing process. This has led to the testing of many new treatment methods, in order to find a consensus for the injury.
LAURA: Kognitiv beteendeterapi för kvinnor med psykisk ohälsa till följd av en traumatisk förlossning : En randomiserad kontrollerad studie av internetadministrerad vägledd självhjälpsbehandling
The purpose of this randomized controlled study was to investigate the effect of internet- administered guided self-help for women suffering from psychological problems following traumatic childbirth. The eight-week treatment program consisted of written chapters based on cognitive behavioral therapy. 56 participants were randomly assigned to a treatment group (n = 28) or a waiting list group (n = 28).The results showed that post-traumatic symptoms decreased as a result of the treatment, with large within-group effects measured by both the Traumatic Event Scale (TES) (d = 1.33) and the Impact of Event Scale-Revised (IES-R) (d = 1.3). The difference between the groups was only significant when measured by the IES-R in which case the between-group effect was large (d = 0.97). The proportion of the participants who showed clinically significant improvement was considerably greater in the treatment group than in the waiting list group.
Inventering av processvattenbalans : fastställande av fjärrvärmedistributionens läckage inom Vattenfall Värme Uppsala AB
Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult.
Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed
daily. The project is performed at Vattenfall´s district heating power plant in Uppsala.
Information is gathered through discussions, drawings of the plant and guided tours of the plant.
Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor
The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.
Analys av framtidens system för hantering av avloppsvatten och matavfall i Eskilstuna
Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.
Utveckling av en ny tillverkningslina
This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.
