Konsolidering av v?vsp?nda papperstapeter: analys och metodutveckling

Printed and painted wallpaper on a weaved fabric backing was a common way to decorate homes in Sweden during the eighteenth and nineteenth centuries. Not much is written about the craftsmanship in relation to the hanging of these wallpapers and even less about the conservation of the objects. Even so, many wall segments remain in situ and in museums and are more often than not in dire need of conservation such as deacidification and consolidation. These are composite objects, consisting of cellulose materials with different properties along with adhesives and paints. Analysis of the materials is required to ensure safe handling and choice of conservation materials, and to establish a treatment plan which will be executed in several steps. This thesis aims to identify these steps and develop a method for conserving the wall segments with suitable materials, preferably without altering the source material to any significant degree.

Kväve i Östra Mälaren : hur kunskap förvaltas och används i tillståndsprocesser

The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

Uttorkning av lera : Orsaker och följder

When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees.       The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.

Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

En metod i förnyelseplaneringen är så kallad ?riskbaserad förnyelseplanering?. Denna metod syftar till att hitta de ledningar som innebär störst risk.

Känsla för vatten : rekreation i innerstad med fokus på bad

This graduation thesis is about baths and beach like places in city centers. It focuses on recreation and the creation and development of public, social spaces in the city containing water as a visual and useable element. The thesis is divided into three parts; background, inspiration and application. The background examines four factors which we consider important for the occurrence of inner city baths; water, the history of bathing, inner city recreation and social life in public places. A discussion of the (future) importance of inner city baths and beach like places' is then presented. The inspirational part is divided into examples of existing places and examples of types of places. The first is used in an attempt to examine the function and importance of inner city baths and beach like places as well as the opportunities and challenges associated with them. The latter contains a presentation of six categories developed by us to facilitate the planning of inner city baths and beach like places.

Kvickrotsstudier: 1. Kvickrotens reaktion på myllningsdjup, kvävemängd och kväveplacering i konkurrens med gröda. 2. Reducerad glyfosatanvändning på trädad åkermark :

1. Reaction on burial depth and nitrogen availability and placement in competition with a crop In this trial it was investigated how couch grass (Elymus repens) changes its ability to compete in stands of wheat and barley with different burial depth and different amounts and placement of nitrogen. More knowledge in this area can be valuable in the attempt to decrease the use of herbicides and still keep the weeds under control. The trial was carried out in the summer of 2004 as an outdoor pot experiment. The pots contained 15 litres of soil with a surface of 0,06 m2.

"Använder ni samma symboler, det gör ni inte va?" : Ikon, index och symbol: En analys av teckenbruk inom Försvarsmakten, Räddningstjänsten och Polisen.

Institutionen för datavetenskap (IDA) vid Linköpings universitet har tillsammans med försvarsmakten, polisväsendet och räddningsverket i Östergötland startat en projektstudie för att utröna huruvida augmented reality-teknik (AR) kan användas för att förbättra koordinationen mellan civila och militära organisationer, och på sikt även militära och civila organisationers gemensamma stabsarbete mellan nationer. Kunskap om hur militära och civila organisationer - som har ett tätt samarbete vid olika former av samhälleliga kriser - ser på sin organisationsspecifika teckenanvändning kan vara relevant vid införandet av ny teknik. Detta i synnerhet om det går att finna skillnader i de olika organisationernas syn på och användning av tecken.Denna studie har gjorts i anslutning till ovanstående projektstudie och fokuserar på hur företrädare från försvarsmakten, polisen och räddningstjänsten, utifrån en semiotisk inramning, ser på sin teckenanvändning. Syftet är att undersöka ifall betydande skillnader i teckenbruk finns hos dessa organisationer. För att nå en större inblick i hur företrädare för de tre organisationerna ställer sig till den egna teckenanvändningen har utdrag ur ljudinspelat material från två olika sessioner analyserats.

Skydd mot yterosion i slänter av finmorän

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

Utvärdering av Ocular Protection Index

Syfte: Syftet med denna studie är att utvärdera Ocular Protection Index (OPI) för att se om det är en användbar metod vid diagnosticering av torra ögon. En del i utvärderingen är att undersöka korrelationen mellan OPI och resultatet på en symtomenkät, Texas Eye Research and Technology Center Dry Eye Questionnaire (TERTC-DEQ).Metod: Försökspersonerna fick i början av undersökningen fylla i TERTC-DEQ. Därefter observerades försökspersonerna vid läsning på avstånd och nära håll för att mäta deras blinkintervall. Försökspersonernas ögon undersöktes med spaltlampa och Tear Break-Up Time uppmättes för att därefter räkna fram OPI för varje försöksperon.Resultat: Totalt undersöktes 34 personer varav 4 personer exkluderades på grund av att de ej uppfyllde urvalskriterierna. Endast mätningar på höger öga redovisas i resultatet.

Energieffektiviserande åtgärderpå Robertsfors VA-nät : En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Balansering av vindkraft och vattenkraft i norra Sverige

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

'Hen i lådan' : Ett arbete om genusperspektivet på förpackningsdesign

'Hir in the box' is a study about the gender perspective in packaging design and how it is today. The study deals with the product category razors, for both women and men, to examine and compare products with the same function but with different designs. Based on an analysis of how packages are designed for different sexes, information should be given on how gender-neutral packaging can be designed and used in the future to reach the market. The purpose of the study is also to contribute to future research on the subject. To fulfill the purpose of this study, nuanced and in-depth data is collected by means of a small-N-study and a qualitative study in the form of open group interviews where the survey units are reviewed and discussed.
