Man spends most part of the day at work and is therefore influenced by it?s ambience. That?s why it?s important that the environment at work is health promoting and can function as a supportive environment. The purpose of this study was to describe job satisfaction among employees and to analyse a possible connection between job satisfaction and employees experiences of SOC.

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

There are a lot of different sounds in our sound saturated time. Noise is an unwishable soundand a high sound level can give short- or lingering problems for both children and adults.The purpose was to find out if and in that case why children and the activity at the pre-schoolaffects by a high soundlevel. Another purpose was to examine what the effects would be if thepedagogues set about the work to get a good sound environment at pre-school.The investigation was accomplished in shape of qualitative interwievs where six pedagoguesfrom different pre-schools answered questions about a high soundlevel.All of them have been educated to hearing pilotes.The result of this investigation shows that some pre-schools have a high sound levels but notall of them. In those cases where there is a high soundlevel are there often too many childrenat the same place on the same time. That makes the soundlevel even higher and both childrenand adults are getting tired.By improving the sound environment at the pre-school both children and adults often gets abetter activity.Keywords: high soundlevel, hearingpilot, noise, affects on children..

The discussion about high culture and popular culture in our society has been going on for decades. In few places is it as loud as within culture journalism and the critics? society, where the question of what is good taste and what is dumb entertainment constantly gets brought to the surface. Film is a particularly vulnerable area, since it is such a universally appealing and rather young medium. In America and England several studies have been performed of the reviewing society and reveiwers? use of high and low art-discourse in their writing.

The purpose of this study was to investigate if preferences for high- and low context communication differed significantly between individuals from individualistic and collectivistic cultures, living in a multicultural environment. A quantitative survey was used as method and the survey was answered by 150 students at Jönköping University and Uppsala University. Two self-assessment scales, obtained from previous studies were used to measure the degree of the two cultural dimensions and communication styles. Two multiple regression analyzes were performed to investigate the connection between collectivist cultures preference for high context communication and individualistic cultures preference for low context communication, that has been found in previous studies. Two ANOVAs were also performed to investigate differences in communication style depending on sex and length of stay in Sweden.

The purpose of this report is to collect, compile and complement the scientific and experience based knowledge concerning high pressure fire fighting today. The goal is to produce a decision data for the Rescue Service concerning the use of high pressure systems for fire fighting. Focus is on hose reel high pressure systems but other systems are discussed too. The report begins by describing the technical properties of the different systems. Then the fire fighting properties are evaluated, including manoeuvrability and safety for users.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

This study will analyze and interpret the performance art piece The Last Strawcreated by the artist group High Heel Sisters. The aim is to search for potentialfeminist strategies in their deconstructive ways of incarnating gender and bodiesusing the notion of performativity and phenomenological theories.My study shows that the diversity of this art performance creates a complex platformwere discussions about gendered corporeality and spatial power relations are beingnegotiated..

The purpose is to analyze if the students have any use of their computer education at a senior high school level or if there is a demand for them to proceed studying. Does the students background have any importance or is it their own motivation that makes the student advance to higher education.In this report we ask ourselves the question, if the students have any use of the knowledge gained at senior high school in computer studies at a higher level. Do the students have any chance for employment based on their senior high school grades in computer studies after graduation?  Do the schools that follow the senior high school guidelines within programming and databases give these students an advantage towards those that have not received the same fundamental education?The method used for the survey is a group questionnaire.  The questionnaire was distributed at one and the same time and then collected to examine the results. The survey results showed that students who seek work based only on their senior high school grades, received only a temporary position for different lengths of time.

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

Our society has become increasingly digitized, and all around us information flows constantly. Knowledge about valuing different sources of information, and not least the information itself, are becoming increasingly important. Media and information have come to play a big role in our society, and knowledge of media and information literacy becomes important to learn in school. High school students are at the beginning of their adult lives as educated citizens.In this study, we measured high school students experience of media and information literacy, during their three years in high school. Students answered a questionnaire, with questions based upon theoretical concepts in media and information literacy.

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.
