Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

Uppsala University is involved in a large international collaborationto build the Laser heater system for the European Xray Free-electronlaser in Hamburg, Germany. In this thesis I describe a laser incouplingdevice into the vacuum chamber of this laser heater all the way fromthe specifications to a completed design.The laser heater is a very important part of the XFEL and thepart described here is a part of the vacuum system needed to couplean external laser into the electron vacuum system and align it withthe electron bunches in order to heat them. The task was started by studying the literature about the basic theory andthe design of vacuum systems. After this study and collection of ideaswith colleagues I started to prepare different concepts to solve thetask. The ideas can be put into two categories, in one case the couplingmirror is located inside the vacuum chamber and in the second caseoutside.

?Studies have shown that patients receiving mechanical ventilation in an intensive care unit (ICU), who are entirely dependent on the nursing staff, often experience frustration due to a temporary loss of the voice source. Limited communication is an important factor contributing to patient discomfort. Nursing staff also report communication as frustrating and difficult.The aim of the present study is to introduce a neck-type electrolarynx as a communication aid in an ICU, to study the nursing staff experiences of communication with tracheotomized patients receiving mechanical ventilation, and to examine the patient´s experiences regarding communicative abilities. Communication between a ventilator treated, tracheotomized patient and members of the nursing staff was recorded and analyzed according to principles of Conversation Analysis (CA).The results show that several members of the nursing staff experience difficulties communicating with tracheotomized patients receiving mechanical ventilation.

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.

The aim of this study was to investigate factors that ex-criminals believe have been of importance to them when they decided to leave a lifestyle of criminality behind. The study was based on eight semi-structured interviews with informants who had committed various forms of crime. Common to all informants is that they are now members in the Swedish association KRIS (In English: CRIS, Criminals Return Into Society), living a life without crime. The stories of the informants have been analyzed on the theoretical basis of social ties, the exit process, role loss, motivation and the life course perspective. Our study showed that the informants have been affected and motivated by various life events that could be identified and pin-pointed during the interviews.

 ABSTRACT  Nature of essay:                C-level, 15 pointsPage count:                        47Title:                                   The last way out?-A qualitative study of psychiatric staff and service users attitude to electroconvulsive therapy (ECT).Author:                              Hanna Nilsson Purpose: The purpose of this study is to investigate attitudes to electroconvulsive therapy (ECT) of professionals and service users within a user organization ? Riksförbundet för social och mental hälsa. (RSMH)Questions: Does the psychiatric staff believe that there are preconceptions about electroconvulsive therapy? What motivates service user?s choice of electroconvulsive therapy? Do the psychiatric staff and the service users think that the positive effects of ECT can outweigh the possible negative side effects?Method: Qualitative study. The study is based on interviews with psychiatric staffthat works with electroconvulsive therapy (ECT), and with services users who have received electroconvulsive therapy (ECT).Results: The result showed that the psychiatric staff feels that preconceived ideas occur about the treatment of ECT, and that it is affecting their approach to work.Service users motivate their choice by how bad they felt under the depression, and that ECT was their only choice left, that´s why psychiatric staff suggested the treatment.The positive effects of ECT outweighed the possible negative side effects because life is something you value higher than any memory loss and when there is currently no treatment having a similar efficiency.Keywords: Electroconvulsive therapy, Attitudes, Side effects, Experience, Patients, Professionals.

The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable. The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.

The purpose of this study is to examine the change in consumer behaviour regarding the intention towards buying fruit when the layout of the fruit section has been altered. We want to increase the probability of making impulse purchases by altering the layout. In our study we have combined structured quantitative observations with structured quantitative as well as qualitative interviews, with secondary data in the form of sales data from two selected ICA-stores. We chose to use this triangulated approach in order to cross-examine our findings and overcome the limitations of one method by the use of another. Further, the Latin square design was used for the observations as a means to acknowledge the calendar effect during the experiment.

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.

Bakgrund: Audiologisk rehabilitering definieras som interventioner i form av instruktion, counseling, hörapparatutprovning och kommunikationsträning vilka används för att minska hörselnedsättningens påverkan på individens funktion, aktivitet, medverkan och livskvalitet. Audiologisk rehabilitering kan utföras såväl individuellt som i grupp. Grupprehabilitering kan vara kostnadseffektivt. Frågan är om audiologisk grupprehabilitering har några positiva effekter och om detta format kan anses likvärdigt med individuell rehabilitering. Syfte: Syftet med studien är att beskriva audiologisk grupprehabilitering och dess eventuella effekter.

ABSTRACT Tobacco Rattle Virus (TRV) is a soilborne plant virus. It is an important pathogen in potatoes where it causes spraing disease. This disease can lead to significant economical loss for the farmer, so it is imperative to get the proper diagnose before planting. TRV is spread naturally by free-living nematodes (Trichodorus and Paratrichodorus). Transference of TRV to a plant occurs when the virus-carrying nematodes feed on plant roots. The relationship between virus, nematodes and plants is complicated, and has to these days not been fully characterized. The diagnostic methods available today do not work sufficiently.

This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.
