This dissertation discusses head librarians in Swedish public libraries and the stress factors which affect them. The aim is to map out potential stress factors which head librarians come across in their day-to-day work. The purpose of the dissertation is to answer the following question: what stress factors affect library managers in Swedish public libraries? The dissertation was conducted through a literature study, informal interviews and a quantitative questionnaire. The results of the quantitative questionnaires show that the factor that produces the highest level of stress is having too many different tasks.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

I dagens samhälle finns det ett antal arbetstagare som har anställning på begränsad tid. Denna uppsats utreder regleringarna kring visstidsanställningar samt vilket förhållande som finns mellan visstidsanställningar och samhället. Fokus i detta arbete är att undersöka hur visstidsanställningar regleras och hur dessa inverkar på individer i Sverige. För att få full förståelse behandlar uppsatsen vidare EU:s syn på Sveriges reglering av visstidsanställda. Samhällets utveckling behandlas kort för att nå en djupare kännedom om behovet av visstidsanställningar i Sverige.

After the last European Union expansion the east European countries became members of the European Union. This meant that they would become apart of the Schengen agreement and that they would be able to travel, live and work anywhere in Europe. This came as a shock tothe Scandinavian trade unions that were worried that work migration would escalate, and that it would lead to social dumping, which would make the working conditions worse for the native workers. .The Swedish labour market is build up by the principal of negotiations. The evolution of the labour laws comes from the rules and regulations of collective agreements.The Lex Britannia principal was made to regulate the working conditions for guest workers in Sweden, by making it possible for trade unions to take industrial action against foreign companies to make them sign a Swedish collective agreement.Even though Swedish labour law includes an obligation to maintain industrial peace it is not valid for foreign companies.

När ett företag inför decentralisering medför det att det uppstår mer eller mindre självständiga enheter, som ofta handlar internt med varandra. Genom decentralisering vill företagen korta ner tiden för beslutsprocesser och ge ett större ekonomiskt ansvar för varje enhet, man vill med detta nå en effektivisering inom företaget. Problem som kan uppstå vid decentralisering är att samordning och kontroll av enheter försvåras. Dessa problem försöker företag lösa genom att införa ett internprissystem. Internprissystemet byggs på företagets specifika situation och dess syfte med internprissättningen. Internprissättning är ett komplicerat område, men det handlar om att kunna styra, kontrollera och motivera de självständiga enheterna.

Swedens membership in the European Union have resulted in an international characterized labour market. The construction sector is the area who employs most posted workers among the 7400 employees who monthly enters the market. It?s also the sector where a big part of the work-related deaths occurs. The purpose of this study is therefore to contribute to a greater understanding of the regulation regarding posted workers, their work environment and the consequences of it.

As consumers we want to know from whom we buy, what we buy and the impact the company has on our planet. In recent years there been an increasing number of scandals concerning child labour, dangerous chemicals and falsely labelled meat. A good way for companies to communicate their environmental efforts is to establish a sustainability report, where they describe their work and their impact on our environment. By concentrating on H&M?s sustainability report, as well as conducting a rhetorical analysis, we have been able to focus on the following research questions:  ? Why do companies establish CSR reports? ? How do companies gain legitimacy through their rhetorical choices? ? How do companies try to influence recipients? attitudes to the company? We begin by studying the context, which is of importance when using a rhetorical method and thereby attempt to understand in what situation the text is created.

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

The technical evolution has a great influence on the public libraries. Electronic media becomes more and more common. This Master´s thesis is based upon the Swedish Library law 9§ (SFS 1996:1596) which says: Public- and school libraries should pay special attention to children and teenagers by offering books, information technology and other media, adapted to their needs, to encourage development of language and stimulate reading. From this point of view we have examined why the children´s departments in public libraries offer CD-ROM games which are based upon characters from the literature, how they are used in the daily activity and how they can contribute to the development of the children´s department.We have made literary studies and empirical investigations including interviews, observation studies etc. The results from this studies shows that both young and adults appreciate the CD-ROM games.

By doing this thesis I want to open up farmers and tractor drivers mind to see that there is several risks with their work. There is a number of risks that everybody probably already know about, and hopefully I will, with this work, help them to see a lot more risks, to make them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward to.

The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

Companies and organizations need to take care of their employees? creative ability. This report gives some examples of work situations that support or prevent creativity. The purpose with this report is to investigate the link between people at work and creativity.It was necessary to delimitate the area and decide which sources to be investigated and presented in the report. The main topic is on sources of creativity, but as more organizations seem to introduce efficiency thinking according to Börnfelt (2009), the interaction between efficiency and creativity is also presented.In this report theory is compared to industrial designers? opinions on creativity.

Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.

International trade in services has increased over the past 30 years as a result of progress in information and communication technology, increased focus on services from the manufacturing sector and the establishment of trade associations.The international market for healthcare services, also referred to as medical tourism, is growing more and more. Patients increasingly seeking treatment at other countries healthcare systems because of long queues within their own country or because it exists better prices for the same care abroad. However, this type of service exports occurs at a limited extent in Sweden.The purpose of this study is to highlight and analyze the conditions for Swedish service companies to export healthcare services. This, includes the challenges and opportunities that exist to expand the exports of these services.The approach for this study has been in the form of interviews with two market actors and written responses, from the same interview guide, with three market actors. These market participants are the so-called Care companies which export healthcare services in various counties, and the membership organization Swecare who work with export promotion activities for its members in the Swedish healthcare sector.
