Background: Surgical complications has been the main cause of medical injuries and deaths worldwide. In 2008 WHO developed the checklist for safe surgery to reduce the number of surgical complications. The objective of the checklist is to strengthen already established safety routines and contribute to better cooperation and communication. Research shows that compliance to the checklist is deficient, which can affect patient safety.Aim: The aim was to study the extent to which theatre nurses participate in the use of the checklist.Method: Observational study was conducted with a descriptive design and quantitative approach. 24 observations were carried out with aid of an observation protocol of two surgical units at a hospital in central Sweden.Result: The results showed that Timeout initiated widely but compliance to all items was considerably lower.

Theft without break-ins has increased significantly in the last year of swimming, sports and leisure facilities in Karlskrona, more precisely 60%. Vandalism in the shape of graffiti is another common crime. The solutions are divided into social and situational crime prevention. Social crime prevention engage in actions that are based on social causes of crime rather than the opposite situational crime prevention, which instead assumes that discourage with the help of technical solutions and has as primary objective to hinder accessibility for example theft friendly goods. The main purpose of this work is to come up with solutions to prevent these crimes, while also being cost-effective and realistic to implement. The work is important in that it creates safety awareness and promotes a healthy safety culture. Moreover, the future goal is to lower these statistics. The goal of the work is in addition to developing our knowledge of crime subject, was also to provide help and solutions for our clients.

This study focuses on the use of animals in social work from the perspective of social workers. The purpose of this study is to examine social workers? experiences of animal assisted social work and how social workers view the integration of animals in various fields of social work. The research is based on a qualitative method and four semi-structured interviews were conducted with social workers. The theories incorporated in the study are Attachment Theory and Sense of Coherence (SOC).The following results are presented: Social workers are considered to have a more comprehensive understanding of clients compared to their associates who do not hold a degree in Social Work.

Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.

Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.

The purpose of this study is to assess the state of health of the individuals living in Löddeköpinge during the middle ages, whose remains were excavated by Chintio, H., 1975-80. The location is thought to have been a trading community that ceased to flourish towards the end of the Viking age. The main focus of the essay is to examine the occurrence of osteoarthritis (sv. artros), trauma, and analysis of stature, in order to understand population health during this time period. Osteoarthritis has never been researched in Löddeköpinge and the analysis showed that, of the 60 skeletons examined, 68,3% demonstrated some change in the skeletal joints, which is much higher than in the comparative material obtained from Lund and Sigtuna.

Det råder bostadsbrist i Stockholm, en lösning är att bygga nya bostäder. En annan lösning är att nyttja befintliga byggnader som inte används som bostäder, genom att bygga om kontor- och industrilokaler till bostäder. Det som händer är att industriområden flyttas längre ut från de attraktiva bostadsområdena. Ombyggnationer av byggnader med olika lokalkategorier kräver omfattande bearbetning och samarbete mellan flera aktörer såsom stadsplanerare, byggherrar, arkitekter, konstruktörer med flera. Det finns många aspekter att ta hänsyn till vid ombyggnationsprojekt och vårt mål är att belysa några av dessa.Den här rapporten studerar först och främst konstruktörens roll, vad en konstruktör ska tänka på vid en ombyggnation.

This study is a value chain analysis for timber in East Africa. It was commissioned by Vi Agroforestry, a nongovernmental organisation registered in Kenya, Rwanda, Uganda and Tanzania engaged in a rural development program that involves promoting tree planting and enterprise development (Vi Agroforestry, 2012). The purpose of the study was to identify and describe common value chains for timber in the countries where Vi Agroforestry operated. Value chain is a concept and a framework describing how to structure information regarding activities included in satisfying a certain customer need, e.g. procurement, logistics, transactions, production and marketing.

The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

Detta examensarbete har gjorts på uppdrag av Skanska Teknik med handledning av Johan Sjödin. Arbetets syfte var att jämföra olika limträförband, utförda av antingen spikningsplåtar eller WT-T skruvar, och komma fram till den bästa lösningen med hänsyn till bärförmåga, kostnad och utförandetid. I ett projekt har de spikningsplåtar, som används vid limträförband, börjat rosta under extremt fuktiga förhållanden fastän spikningsplåtarna är rostfria enligt tillverkaren. En fördel med WT-T skruvar är att de är gömda inne i träet och på så sätt inte i direkt kontakt med den aggressiva miljön, men även skyddad mot brand. Andra fördelar med WT-T är att utförandetiden är kort och kostnaden är lägre än spikningsplåtsalternativet.
