This master thesis in energy optimization was made during the autumn of 2006 at Käppala wasteWater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

To achieve the goals that the government has put in place for equal opportunities in the labour market, the Swedish law is divided into two separate regulatory frameworks. One is positive action to promote equal opportunities and the other is the prohibition of sexual discrimination. Since males, despite the measures taken so far, still have a great advantage on the labour market, the law concerning equal opportunities has an exception from the prohibition of sexual discrimination, whose purpose is to promote the progress of equal opportunities, also known as preferential treatment. The regulations concerning preferential treatment allow the employer to hire a less qualified person from an underrepresented gender in spite of the presence of higher qualified applicants of the overrepresented gender. The purpose of this paper is to investigate the meaning and the application of preferential treatment as well as to give an insight to the argumentation around its application.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

The purpose of this study is to examine the personnel?s perspective on how the emotions shame and guilt are present in the treatment of female addicts on an LVM institution. Three questions have been designed to meet the objective: How do they work in the treatment with guilt and shame, how important is it to work with these feelings and what significance does genders have in relation to shame, guilt and treatment? A qualitative approach and techniques have been used to obtain the result. The study's theoretical starting point consists of three themes: gender theory, labeling theory and a theoretical approach to the concepts of guilt and shame.

BackgroundAnorexia nervosa is a growing problem in society and it is most common among women. It is a complex disease that affects both the mental and the physical health. The disease expresses itself differently from person to person, therefore, treatment should be individualized. Nurses need to gain insight into how patients feel about the treatment in order to understand their experience. Previous studies use statistical research to evaluate treatment.

The project was initiated by Medipharm which produce microbial inoculants which used as additives to preserve forage. The main goal was to test three inoculants to produce maize silege. The following Medipharm produced inoculants were tested, Milab 393, Lactisil Wolecrop II, Lactisil 300 2. An untreated control was included in the study. The trial was done at Swedish university of Agriculture and Science in Alnarp, Sweden. Eurostar was the cultivar of the maize and was grown on 20, 5 hectares.

The aim of this paper is to spread some light over contract treatment from the perspective of the District Courts, Social Services and Probation Services, and understand the reason for local variation of the number of people sentenced to contractual treatment.Essential questions asked in this paper are; What advantages and disadvantages are known by the cooperating parties regarding contract treatment in comparison to prison? What parameters are considered when the cooperating parties decide upon contract treatment? What impact does the shared responsibility of cost have? What do the respondents think is the reason for the local variation?In order to answer the essential questions a qualitative and descriptive method has been used to highlight the main question of our study; What is the reason for the local variation in number of contract treatment sentences in Halmstad and Ystads district courts?The paper shows that the local variation between the Probation Services districts is dependent on the conditions to propose a contract treatment. In Halmstad it is not conditioned for the Probation Services to have a responsibility agreement with the Social Services to the same extent as for the Probation Services in Ystad..

This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

The purpose of thesis was to investigate and compare how two companies within pharmaceutical industry and nuclear power industry are currently working with quality development regarding continuous improvement and Lessons Learned in business processes. In addition, a simple comparison was made with the automotiveindustry.McNeil AB are improving their processes continuously and are according to the findings of this report performing well in their pursuit of world-class pharmaceutical production. They have a well functioning process regarding improvements proposed in weekly improvement meetings engaging all employees. However, during interviews it was made clear that the functionality of the process which administer improvement proposals generated in addition to, or beside the weekly improvement meetings, were inadequate. McNeil AB is proposed to administer this through an IT solution instead of by paper and e-mail, that simplifies the process of adding, implementing and follow up an improvement proposal.The nuclear power plant Ringhals AB recently made major improvements in their business processes as well as the plant itself.

Aims: To examine how patients with experience of being involuntarily discharged from medication-assisted treatment with methadone or buprenorphine have coped with the consequences following the discharge. The study also aim to examine how the patients cope with the stigma related to their abuse of heroin and how they manage to cope with the rules regarding themedication-assisted treatment. Method: Three patients with experience of involuntary discharge from medication-assisted treatment have been interviewed. All were heroin abusing men living in Stockholm. The interviewees were recruited through the Swedish Drug Users Union and through a shelter for homeless people with drug problems.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

In this thesis an energy analysis of ethanol production at the ethanol plant of Lantmännen Agroetanol in Norrköping has been performed. The ethanol plant has been studied in combination with Händelöverket, the combined heat and power plant which provides the ethanol process with steam. The purpose of this study was to determine the energy consumption for the whole production chain from grain to ethanol. The analysis has included the energy consumption for cultivation of grain, production of chemicals, the production chain for wood chips, the steam production and the ethanol plant. The grain and wood chips are both considered raw materials there for the energy content in these are not included as energy input in the system.
