This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

En betydande andel individer med bipolär sjukdom upplever kvarvarande, subkliniska symtom mellan egentliga sjukdomsepisoder. Sådana restsymtom är förenade med sänkt livskvalitet och förhöjd risk för återfall i sjukdomsepisoder. Syftet med föreliggande studie var att undersöka huruvida en kort, internetadministrerad behandling är genomförbar och kan ge en minskning av depressiva restsymtom, genom interventioner riktade mot sömn och emotionsreglering. För detta syfte användes en single-subject design med upprepade mätningar (n=4). Studiens resultat visar att behandlingen är genomförbar och att den, för vissa individer, kan ge en minskning av depressiva restsymtom.

Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

It is more common now to purchase products and services on the Internet. More and more companies choose to sell their services and products this way. Some services and products the customers can get delivered directly to their computers. Therefore, it is important for entrepreneurs to know when they risk a permanent establishment in another country due to their Internet based activity. If the company gets a permanent establishment in the other country, the other country can tax the income which is relatable to the company?s permanent establishment.

In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Some people who recovered from exhaustion disorder report that their lives feel more meaningful after the disease than before, despite residual symptoms and difficulties. This experience of increased meaningfulness has been linked to sense of coherence, SOC. The research question was whether individuals with exhaustion disorder at onset has a weak SOC, and if there is a general increase towards a higher SOC value ??during the recovery process. In a cross-sectional study, data were gathered on the SOC value via the SOC 29 form.

Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.

Background: Charity and other non-profit organizations have traditionally not been subject to any particular regulation enforced by Swedish law. Recently though, accounting standards have been altered which, through the new "Bokföringslagen" as of first of January 2001, have affected accounting standards for non- profit organizations. One of the implications which the new"bokföringslagen"has for non-profit organizations in Sweden is the link which it establishes with other accounting regulations enforced by the "Årsredovisningslagen". This link will, in turn, determine which rules that apply for any particular organization. Purpose: The purpose of this thesis is to examine how accounting regulations are handled by Swedish non-profit organizations.

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

This is an explorative study about subject indexing of a special collection of books, administered by the John Andrén Foundation at the library of Ystad. The study summarises a number of theoretical perspectives as well as some practical instructions on how to carry out the task. Theories have been placed into five different groups according to their various approaches to subject indexing. These have been analysed in regard to their usefulness to the Andrén collection. The authors have tested and evaluated six practical models on a selection of books from the Andrén collection.
