Jakten på kulturplanering. En textanalytisk studie av instrumentell kulturpolitik i Göteborg.

The aim of this study is to explore local cultural policy documents in the municipality of Gothenburg Sweden, and, more specifically, to investigate the concepts of cultural planning and instrumental cultural policy. Cultural planning is in this thesis seen as a result of an instrumental view of cultural policy. The theoretical framework consists of the theories of Danish cultural policy researcher Dorte Skot-Hansen. She describes cultural policy in urban areas as founded in motives such as economy, social issues, entertaining and enlightenment. A qualitative text analysis is performed in order to see if the purpose of the cultural policies is to focus on cultural planning as formulated in the document Kulturpolitisk strategi ? version 1.0, adopted by the city council in 1998.

Redesign of an existing apartment block in Kv Preussen to passive house

Passive houses are a relatively new concept in Sweden and by that it is meant a house without a traditional heating system. The most acknowledged passive house project is the terrace houses in Lindås, Gothenburg, which we have used as a reference. This project concerns a square apartment block. So far, no square apartment block has been built as a passive house in Sweden.The common opinion in the construction industry is that it is not economical to build extremely energy efficient houses. With Peab as commissioner our task was to investigate if that is true, if regarding the construction of a multi storey house as a passive houseMidroc, now owned by Peab, constructed in the block of Preussen in Jönköping during 2004-2005 four houses, with 132 apartments distributed on seven floors.

Automatisk lockmekanism : från idé till prototyp

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

Småskalig säsongslagring av solenergi för uppvärmning av bostäder : Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

Brott och straff under 1600-talets första del : En komparativ undersökning av Sjuhundra härad och Njurunda härad

The aim of the study was to investigate the crimes and punishments that were commonly occurring between the years 1601-1651, and how the distribution was between men and women represented in the court in district Sjuhundra and Njurunda district. To answer these questions, a quantitative examination of court records conducted in which the crimes and punishments have been categorized. The results that have emerged have been the basis for the conclusions issued in the essay. The results showed that the most common target types were various civil and propertycase and the most common punishments were sentenced to fines and settlements. It was predominantly men who were in the court, the proportion of women was between 13-22%.

Kirunametoden-Jämförelse emot en konventionell injusteringsmetod

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

Hur byggnadsdetaljer ändrar fasadens uttryck

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

"Inte mitt arbete...men det hänger på mig" : Hemtjänstpersonalens uppfattningar av sitt arbete i hemsjukvården

The proportion of elderly people in Sweden is increasing. Many of these live at home and as their age increases so does the likelihood of health problems and the need for support, medical attention and care. Personnel working with home help provide a large part of this care, including areas of home-based care that are the responsibility of the district nurse. The purpose of this paper is to describe how home-help personnel perceive their work in the area of home-based care, as their views are an important factor in the ability to provide a care system that funktions successfully. The method employed here is phenomenografic and nine subjects from a home-help group have been interviewed.

Optimalt råvarulager för biobränsleföretaget :

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger District heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large District heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

Utredning av värmepump med fjärrvärmespets

Det här är ett examensarbete som handlar om en fastighet som står på Norra Kungsgatan 37-43 som har både en värmepump och fjärrvärme för uppvärmning. Värmepumpen används i första hand och fjärrvärmen används som spets när värmepumpen inte räcker till. Detta är en ganska ovanlig kombination. Syftet med arbetet är att ta reda på om detta är en bra lösning och om lösningen är lönsam. För att få fram hur stort fastighetens energibehov är så görs beräkningar utifrån fjärrvärmedata från tidigare år samt en gammal värmepump som är utbytt sedan 2011.

Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk

The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.

Företagsstudie om värmeöverföring : Beskrivning av värmeflöden hos en lagerbyggnad

The study took place at a food corporation in Växjö, Sweden. It describes a building that contains four tanks in which glucose syrup is stored. The purpose of the study was to calculate the amount of heat that leaves the building and the amount of heat that is supplied by the installed heating equipment. Before the calculations could be implemented, all the systems that supply the building with heat had to be examined. With a small amount of information from earlier studies, the work to gather all the data necessary for the calculations began.

Distriktssköterskors och sjuksköterskors upplevelse av arbetsmiljö i primärvård och en kartläggning av arbetstidens innehåll

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.

CFD-simulering av kallras från fönster : Konvektorers och nischdjupets inverkan på lufthastigheter i rummet

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.
