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.

Swedish healthcare systems have endured harsh criticism from healthcare professionals because of their inability to understand healthcare processes. These systems have been identified as significant time consumers, and Swedish healthcare is therefore facing a major challenge to assure patient safety. The following paper is based on a workplace study, which aims to examine healthcare systems? impact on physicians? practices. Our findings show that physicians spend substantial amounts of time chasing information, rather than managing information and pursuing healthcare.

När man studerar till sjuksköterska och fördjupar sig inom vårdvetenskapen benämns patienter kategoriskt med just begreppet patient, oavsett var i vårdsystemet denne befinner sig. Begreppet patient har innebörder och värderingar som inte alltid syns och som påverkar relationen mellan vårdgivare och vårdsökande. Begreppsanalys är ett sätt att konkretisera och synliggöra ett begrepps innebörd. Vi valde att använda oss av Walker & Avants modell för begreppsanalys. Denna innebär att man definierar de avgränsande attributen och skiljer dem ifrån de ovidkommande attributen.

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.

Diabetes type 2 is a fast growing illness and a global health problem, often a result from less appropriate standard of living. Lifestyle changes related to diet and physical activity are important lifestyle changes regarding to get control of the self-management and to avoid vascular complications.AimThe aim of this study was to describe patient's experiences of lifestyle changes in diabetes type 2.MethodA literature study was carried through based on 12 qualitative scientific articles.ResultsThe analysis result into two main themes and eight subthemes. Main themes where barriers and motivators for lifestyle changes and the subthemes where struggle, denial, lack of knowledge, alienation, support, motivation, acceptance and knowledge.ConclusionThis study shows that lifestyle changes are experienced different by patient with diabetes and nurses should therefore be aware of the unique and specific demands these patients require. This is important for providing a good diabetic healthcare and to help patients with their self-management.

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.

The aim of this study was to examine the existing discourse of youth robberies from year 2003 to year 2013 in DN and Aftonbladet. By using discourseanalysis as theory and method I have studied newsartikles from these two newspapers.The study shows that the portrayal of youth robberies is focused on the young muggers as a group and not as individuals. The groups that are mentioned are young men and women, children and muggers with another ethnical background than swedish. Girls, children and ethnical background are given more attention in the articles, and are portrayed as more problematic. The youth robberies are described as brutal and are focused on the young muggers as unrestrained, evil individuals with no future.The analysis also shows that a change in the discourse is taking place during the studied period.

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.

Identity includes an individual´s self-image and the consciousness about their self. It is about being the same person despite changes in their life situation. The identity often get´s fragile because of the disease. Beacuse of the individual´s feeling of lost identity there may arise a conflict between the person and people in his or her surroundings. They may no longer see the sick person in the same way as they used to.

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.

Bakgrund: I dagens sjukvård förekommer möten som inte uppfyller de kriterier vilka ligger till grund för ett förtroendefullt möte mellan sjuksköterska och patient. Dessa grundpelare är trovärdighet, kunskap/utbildning, attityder, tid och närvaro. Syfte: Syftet med studien är att belysa förutsättningar och hinder för att förtroende skapas mellan vårdare och patient med långvarig smärta. Metod: Författarna har använt sig av en litteraturstudie med kvalitativ inriktning. Studien är baserad på fyra vetenskapliga artiklar och två avhandlingar. Materialet har analyserats med hjälp av Burnards analysmetod. Resultat: Resultatet visar att patienter med långvarig smärta kan ha svårt att känna förtroende för sjuksköterskan. Slutsats: Ett förtroendefullt möte speglas av många olika samverkande delar..

Varje år insjuknar ca 25-30 000 människor i stroke i Sverige. Sjuksköterskan måste ha i beaktande att dessa patienter kan ha kommunikationssvårigheter av olika grad. Syftet med studien var att undersöka och beskriva hur sjuksköterskan ska gå till väga när hon ska kommunicera med en patient som har fått diagnosen stroke. Resultatet visar att sjuk-sköterskorna ofta saknar kunskap i hur hon ska agera och bete sig när hon kommunicerar med en patient som fått diagnosen stroke. Brist på tid är också ett vanligt förekommande problem som gör att sjuksköterskan helt enkelt inte hinner lägga den tid som krävs för att kommunicera med den individ som insjuknat i stroke.
