Textilhantverkets betydelse i Uppåkra - en studie av Uppåkra och närliggande agrarboplatser

This survey deals with textile production and how it was carried out during the late Iron Age,with main focus on a central place, Uppåkra. A comparison has been carried out betweenUppåkra and two agrarian settlements, Fosie and V. Karaby, from the nearby landscape toinvestigate whether any variation in production can be detected. The value of textiles has alsobeen investigated to determine whether a potential specialization in production may have ledto a surplus.An analytical and comparative method has been used with focus on the context of thematerial.The results show that the textile production vary at the different sites, and that a need fordifferent types of textiles has existed. At Uppåkra, the possibility to produce fine threads andtextiles existed as demonstated by the findings of small and lightweighted spindle whorls.This suggests that the production may have included both fine and coarse textiles.

Lean i akutsjukvården: Flödeseffektivisering och slöseriminimering ? en fallstudie av Sunderby sjukhus akutmottagning

På grund av en ökad befolkningsmängd och nya tekniker som gör fler sjuka går att bota ställs nya krav på svensk sjukvård. Sjukvården måste möta de nya kraven med ett bättre effektivare resursanvändande och där till krävs nya förbättringsmetoder. Med influenser från industriell tillverkning har sjukvården omarbetat lean production för att skapa ett universellt förbättringsverktyg som lämpar sig för vårdorganisationer. Verktyget kallas lean healthcare och är omdiskuterat och dess effekter tvetydiga. Att undersöka om och hur värdeflöden i en akutmottagnings triage, som innebär en prioritering efter patienters allvarlighetsgrad, kan effektiviseras med hjälp av ett flödesorienterat arbetssätt som lean.

Flödesekonomins dimensioner : supply chain management

It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company.

Utveckling av en ny tillverkningslina

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

Pottaskeframställning och tjärbränning i Femsjö socken från år 1700 till 1900 :

Femsjö is a small parish situated in Hylte municipality, Växjö diocese. The parish has a total area of 8230 ha of which 5000 ha are covered with forest. There have not been any large industries in the parish offering work opportunities for the inhabitants, so they have had to generate income from their land and the forest. Instead of going to the bank to get a bank loan the people of Femsjö parish went out in to the forest and harvested trees for timber and extra cash revenue. Production of pine tar and potash were two other ways that the residents of Femsjö parish could earn extra money for the household in order to keep starvation away.

Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Akka. Ett skrivbord för hemmet anpassat för rullstolsburna.

A woman is dying of cancer, she refuses to use her walking aid. Because she is embarrassed. This means she can?t leave her house, and her last days become very limited.Why do we act like this?Can the view we have of products adapted for disabled be changed by working with colour, texture, form and materials?There are many products adapted for disabled, the products often have a good function and well developed ergonomic aspects but the visual aspect leaves a lot to wish for. There is neither effort nor money put in to the exterior design of most of these products.A lot of the solutions that are invented for adapted products can be used in design of ?regular? products.Why should we then divide products in to adapted and non-adapted.

Hållbarhetsredovisning är frivillig och det finns flertalet organisationer som tagit fram principer och riktlinjer till företagen. En av de större organisationerna är Global Reporting Initiative (GRI) som tagit fram ett ramverk för hållbarhetsredovisning.

Exponera mera : ett arbete om skyltning på bibliotek

This Master s thesis deals with the display of library media, whether it is conceivable and desirable to draw inspiration from the retail business when displaying articles. The questions asked are: are there, in the retail sector, well established display ideas and - if so - what do they look like? Are the similarities in conditions, between the branches, sufficient? In conveying the ideas to libraries, are the potential differences not obstructive? Is there, among librarians, a positive attitude towards further development of library display techniques? The results were achieved by interviewing shop window dressers and librarians. In addition, a survey was sent to the library managers of 65 public libraries in southern Sweden. The results show that there are established ideas and methods of displaying materials, and that the ideas are manifested in frequently used techniques.

Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

Riktlinjer för enskilt avlopp : Underlag för bedömning av normal och hög skyddsnivå i Köpings kommun

In Sweden, the eutrophication of lakes, water courses and the coastal areas is considered the major threat to aquatic ecosystems and therefore actions taken to reduce the nutrient load to aquatic system including the Baltic Sea has high priority. There are many different sources of phosphorous and nitrogen and domestic wastewater is one contributing factor to the high load. Especially waste water from households that is not connected to municipal sewage treatment or a local small scale plant with appropriate nutrient removal efficiency is considered a problem. These types of households are quite common in rural areas in Sweden and in areas where summer houses has been converted to permanent living. Swedish legislation now permit the municipalities to decide in which areas within the municipality higher demands of the local small scale treatment facility should be met by the households (i.e.

Kontraomvändelse - blivandet av en ateist : en religionspsykologisk undersökning av byte från religiöst orienteringssystem till ateistiskt

The purpose of this study in the psychology of religion is to explore the process of an individual?s shift in orienting system, from a religious to an atheistic. The materials used are autobiographical accounts obtained from two books. One that has been used as a primary source and one as a secondary. By using Rambo?s process oriented theory of religious conversion relevant themes and categories were chosen and later subjected to further analysis using Pargament?s theory of religion and coping.

Tolerans eller normkritik? : och en analys av användning av lärarhandledningen Någonstans går gränsen

This study deals with how the Swedish school system handles questions concerning sexuality and normality. It is also an analysis of how the guidance material Någonstans går gränsen from RFSL Stockholm is used and could be used in teaching.The study consists of two parts. The first part is a study of literature that portrays how teaching concerning these issues is performed in schools, what methods that are recommended and what methods are actually used in teaching. The second part consists of interviews with people dealing with these issues in school and in organizations.My results show that schools often use a ?pedagogy of tolerance? while the guidance material and the research and theories concerning sexuality and normality advocate a more ?queer pedagogy?.
