Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.

This report is a degree paper made for the Engineering program in Technical Chemistry at the School of Engineering, Jönköping University.The intention of the project which is described, is to answer whether HV71 might become environmentally certified according to the criteria of "miljödiplomering". The project also included an investigation of which further steps and measures must be undertaken by the enterprise in order to achieve the certificate. The final part was to implement the necessary requirements for the certification.The report starts with a short background where the origin and function of environmental management is briefly explained.The report continues with how the practical work with the environmental certification was done according to requirements of Jönköping municipality. Motivations behind each part of the process are given as well as explanations of how each part of the process was carried out.The final result of the project was that HV71 took the measures needed to live up to the required demands. After a revision made by Miljöstrategen i Jönköping AB, HV71 passed the demands and became thereby an environmentally certified business..

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

This study is a qualitative investigation where surveys where performed on five Swedes from Lebanon. The purpose with the survey was to learn how these persons were affected by the war against Lebanon in the summer 2006, how they reacted to it and what measures they took to overcome their crisis. The result shows that the state of crisis of the interviewed persons was caused by several factors, such as the war being both unexpected and intensive. Other causes was the worry that their children would be hurt by the effects of the war as well as the material and human losses that the war brought.The interviewed persons responded with both negative and positive reactions, which may have affect their recovery process. Some of them where offered physiological support in Sweden by their municipalities.

The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.

The purpose with this study was to systematically examine scientific studies of audiologic group rehabilitation. The definition of audiological rehabilitation was explored, different variables that influence the result and how the outcome measures should be done and its relationship with the goals of audiologic rehabilitation. The method used was a literature study. Pubmed and Cinahl were used for the search of literature. Some articles were searched from scientific studies reference lists and also advice from the supervisor.The result from the different studies shows that the effect of rehabilitation varies as there are many aspects that have an affect on the outcome measure.

Attitudes towards violence were assessed using both implicit (The Single Category Implicit Association Test; Karpinski & Steinman, 2006) and explicit measurements (a Feeling Thermometer). A group of criminals showed more positive explicit and implicit attitudes towards violence than a group of non-criminals. In addition, The Aggression Questionnaire (Buss & Perry, 1992) revealed significant differences in aggression between the groups; criminals' mean scores were higher on all four subscales (physical aggression, verbal aggression, anger and hostility). Furthermore, significant correlations were found between all the measures, including the implicit and explicit attitude measures. The findings support the validity of the SC-IAT as an implicit measure of violent attitudes.

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

Approximately 400 people in Sweden die each year by lung cancer caused by radon gas. Authorities have in recent years invested big resources and organized campaigns to encourage people to take action against high occurrence of radon in residences. With low frequency of applications for radon allowances as the main measure, a lot interprets on a very low commitment. The purpose of this thesis is to investigate the reasons for the low commitment among people. The study is based on a questionnaire survey sent to 444 house owners in Uppsala.

I have conducted a study and examined the significance and extent of bullying. I will also examine whether any students in grade eight have been victims of bullying during the past year and where bullying was carried out in school X. The second objective is to explore what students think about the concept of "taunting". I have used various theories of researchers to get an understanding of what bullying is, where it occurs, causes, and suggestions for measures. To get an answer on the purpose and issue a quantitative method was used in the form of a survey. Target group for the survey consisted of students from grade eight schools in X which is located in a suburb of Stockholm. Two classes of grade eight in School X carried out the survey during the same day.Results showed that bullying occurs at X school, but that the proportion of boys has been more subjected to bullying than girls. The majority of the students in the both classes believed that most cases of bullying occur in school hallways, playground and cafeteria. It may be one reason why school X does not have guards or other members of staff. The majority of students also considered in the survey that the concept of "taunting" is to call each other by words of ?genitalia". I think that the use of foul language has become common in today's schools.  .

The purpose of this essay is to describe and partly explain the migration from a German city, and to illustrate the political difficulty surrounded by the phenomenon.I?ve composed following question issues to fulfill the purpose of the study:1.How does the migration take form in Cottbus?2.Why do the students want to migrate?3. Do the politicians consider the migration as a problem? What kind of measures do they want to introduce to prevent it?The survey has been done with mainly qualitative research methods, but it contains some quantitative elements.I?ve made an opinion poll survey among students in Cottbus, interviews with politicians at the city council and interviews with four students that have already left the city.The results of the study show that the will to migrate is widespread by the students in Cottbus. It?s first and foremost the chance to get a job that drives the students to migrate.The city has a deficit of 180 million Euros in household, which makes the politicians to feel helpless, facing the problem of migration.

This essay is a case study that deals with the integration of Scania into Sweden,which started for over 300 years ago. The purpose is to capture why theintegration of Scania succeeded, what were the main reasons or factors and todiscuss the effects the scanian identity and culture had on the integration. This hasbeen done with the help of different theories that will help sort out main factors tothe successful integration. The result of the study revealed a number of factors, tobegin with the scanian identity appeared not to be such a great obstacle for theintegration that one could believe. The identity developed because of the?swedification?, which were the measures the Swedish government took tointegrate the new territory.

Although women express a desire to be managers and although they constitute the majority of Sweden's newly graduated academics, they are still heavily underrepresented on senior management level in the Swedish private sector, where men hold as much as 95 % of the top positions. Considering the massive waste of resources that this implies, this thesis sets out to investigate the underlying reasons for the skewed gender distribution on senior management level in two Swedish professional services companies - an industry where the described problem has been palpable. Additionally, the thesis explores the effects of actively working for increased gender equality. With a basis in gender and organization theory, a broad theoretical framework has been compiled and applied to a qualitative case study design. The thesis reveals seven distinct impediments, which together create a parable of an obstacles course, that prevent women from advancing the corporate ladder in the same manner as their male colleagues.

This study examined the psychological processes of autonomic arousal and distress, erroneous beliefs about sleep, worry about sleep, selective attention and monitoring and safety behaviours related to sleep, on the subject of daytime impairments associated with insomnia. The psychological processes were evaluated against as follows: sleep measures, anxiety, depression, medical disease and the use of medications. The measure daytime impairments complied with the established research diagnostic criteria. A correlation analysis indicated that psychological process, anxiety, depression and one of the sleep measures are associated with daytime impairments. The results of a multiple regression analysis proved that only erroneous beliefs about sleep, worry about sleep and safety behaviours related to sleep are linked to daytime impairments associated with insomnia.

Every year an avorage of 40 000 Swedes fall ill with different forms of cancer. Chemotheraphy has an effect on the tumour cells as well as the healthy cells in the body, this causes many side effects which can be very problematic for the patient. The study was carried out in order to indicate the care measures that are taken to deal with the side effects i. e stomatit, loss of hair and sickness/vomiting, that are connected with chemotheraphy so that the outpatients will experience a quality of life. The method used was a qualitative interview with six nurses from the South if Sweden, all of whom are working with chemotheraphy patients.
