In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

The purpose with our essay was to examine which clients/patients get treatment for alcohol problems from either health care units or social service units. We also wanted to find out how staff in these units considers the importance of social background in the assessment of treatment. The questions we have focused are: How do the clients/patients get in contact with the units? How does staff in these units consider the importance of social background in the assessment of treatment? How is the social background like for the present clients/patients? To fulfil the purpose with our investigation and to get answers to our questions, we performed an explorative examination and applied a qualitative method in the form of a semi-structured interview with six persons. The investigation showed that clients/patients get in contact with the units by looking for treatment by themselves or by relatives and other organisations.

I dagens samhälle har många kundföretag problem med datalagringen vilket beror på att behovet av att lagra data började öka kraftigt under 2000-talet och har fortsatt öka sedan dess. När kundföretagen började använda sig av virtualisering så expanderade även datastorleken. I samband med att datastorleken växte ville företagen att data inte skulle lagras lokalt utan att den skulle vara lagrad på en central plats som en serverhall och vara överskådlig.Studien utfördes på tre sätt, först undersöktes vilka datalagringslösningar som fanns och det skedde genom litteraturstudier. Därefter kontaktades företag som använde olika lösningar för datalagring. Nästa steg var att kontakta de leverantörer som kundföretag använde sig av och som levererade lösningarna.Under arbetets gång upptäcktes olika lösningar på problematiken med ett ökat datalagringsbehov.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

Entrepreneurial failure is probably a subject that is not well understood. This might have to do with the methodological difficulties of screening out failed entrepreneurs. In this thesis a tool is developed for analyzing supposed entrepreneurial failure. In this model entrepreneurs are surrounded by different stake holders. By using the failure deconstruction model to analyze my own entrepreneurial effort I find that it has neither been a successful project nor a disastrous one.

Background: Pain can be a constant problem in many older people's daily life, associated with particular physical and social disability, depression and poor quality of life. Dementia diseases are often associated with old age. Communication difficulties are one of the consequences of the disease, which clarifies the role of nursing staff in detecting and assessing pain. Objective: The aim was to compile knowledge about how nursing staff can identify pain in people with dementia. Method: A systematic literature review, where data were collected through manual and database searches.

AbstractThe purpose of this essay is to investigate the views Swedish elementary school teachers produce on the subject of ethics. The teachers? thoughts on selection among ethical notions is described and also how these notions are assessed. The essay proceeds from the central content and the knowledge requirement in the syllabus of religious knowledge.The empirical survey is based on qualitative scientific interviews with four teachers employed in grades 4-6 at different schools.The teachers find ethics in its current state of the syllabus hard to define and they find encounters with parents and pupils difficult in their tasks. The selection of ethics is decided by previously planned basic values education or from conflicts erupting during schools hours.

The aim of the study was to investigate the performance of postlingually deaf adults on parts of the swedish dysarthria test Dysartribedömningen, and to compare these results with a matched group consisting of normal hearing speakers without any known speech disorder. The group consisted of 17 participants ranging between 42-86 years of age. Participants were assessed focusing on articulation, prosody, intelligibility and through a self-assessment of communicative participation. There was a statistically significant difference between groups on prosody that manifested primarily as a slower speaking rate in the cochlear implant users. No significant differences between groups as to articulation, intelligibility or communicative participation could be found.

This paper examines and analyzes effects of the introduction of a new management control system tool within a Swedish public health organization, the Södra Älvsborg hospital, and its possible effect on organizational change. The new management control system tool, known as the SÄS-model, has been widely criticized for being too costly and with too small positive effects to be shown. Our approach has with that as a background been to examine whether the implementation of the SÄS-model and its balanced scorecard has been able to result in effects regarding organizational change. We have through a case study aimed to analyze how a management control system, much alike one that is typically used within foremost private organizations, can promote organizational change. Our results suggest that the implementation of the SÄS-model and the balanced scorecard has given the organization clearer visions and goals.

When the local authorities establish a plan for land use planning, they have to judge if the influence on the environment could be of such a grade that they have to make a special Environmental Impact Assessment (EIA), following national laws and EU-directives. The laws for the process in Sweden is set by the Swedish Parliament, with advisory given by the central government authority, the National Board of Housing, Building and Planning, Boverket. For EU, the laws is set by the European Parliament and the Council. The laws and directions for this process have been changed for Sweden in recent years, and the aim of this study was to compare the contents of three different Environmental Impact Assess¬ments to see if there has been any change in appearances and content in later years, as well as to see if different municipalities and authors have effect on the EIAs. According to different studies some of the EIA done are without insufficient focus on main environmental issues in the EIA, or even that some information is missing.

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

Detta examensarbete har utförts på Vattenfall Eldistribution AB i Trollhättan och syftar till att beräkna förlustförändringarna i lågspänningsnätet då mikroproduktion i form av solceller ansluts.Genom att ansluta mikroproduktion i lågspänningsnätet kan nätets energiförluster reduceras. Denna reducering samt den energi som inte behöver överföras från överliggande nät anses vara den nätnytta solceller ger upphov till.Samtliga elproducenter som är anslutna till elnätet har rätt till ersättning för nätnytta uppkommen av produktionen. Ersättningen skall baseras på inmatad energi samt vid vilken tidpunkt inmatningen sker. För mikroproducenter är det svårt att motivera att i varje enskilt fall beräkna nätnyttan, varför ett generellt schablonvärde beräknats för Vattenfalls lågspänningsnät. Beräkningen har utförts utifrån uppmätta sol- och lastdata på sex olika lågspänningsnät vilka tillsammans anses representera ett generellt nät.
