This report is focusing upon relining from a client?s point of view. Potential buyers are given a presentation of the different methods available today together with a general briefing describing the process. An important part of this report are the interviews that took place with already established customers. Property owners, managers, pipe cleaners, and project managers whom all been in contact with relining have answered the questions given along with their own thoughts and have also given recommendations of other persons to talk to.
Utsläpp av växthusgaser under islossning i små boreala sjöar
Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.
Cleaning process of abattoir wastewater with focus on bacterial pathogens
This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch
reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way.
The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was
analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.
Grundvattnets geokemi vid Gladhammars gruvfält, Västervik. Effekter av äldre tiders kobolt- och kopparbrytning
The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.
Personlig hygien på stycknings- och charkanläggningar : hur personalen på tre anläggningar följer och ser på rutiner för personlig hygien
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.
Amfibier i nyanlagda våtmarker : En fältstudie i Laholms jordbrukslandskap
Many species of amphibians are threatened both in Sweden and globally. The causes are many and a main factor is habitat alterations which often results in populations being isolated. Changes in the agricultural landscape have among other things resulted in small water bodies being filled and dried out and that has severely affected the Swedish amphibians. Swedish amphibians are depended upon small water bodies for their reproduction. Wetlands have been constructed to reduce the impacts of the eutrophication in the Laholm bay.

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.
En storm i ett snapsglas : Slutstriden om det lokala vetot 1917
Min B-uppsats, motsvarande 7,5 högskolepoäng, har titelnEn storm i ett snapsglas ? Slutstriden om det lokala vetot 1917 och har till syfte att, med hjälp av statsvetenskaplig rationalistisk (spel)teori, analysera 1917 års stora alkoholförsäljningsdebatt i andra kammaren, vilken ägde rum den 2 och 9 maj detta år. Som bakgrund till denna studie redogörs först för hur de svenska nykterhetsrörelserna, genom förbudskongresserna och Sveriges nykterhets-sällskaps representantförsamling, förenade sig till en mycket kraftfull folkrörelse kring 1900-talets början. Även om den samlade nykterhetsrörelsen redan från början kunde dra nytta av 1855 års försäljningsförordning, vilken gav kommunerna rätt att bilda systembolag med monopol på brännvinsförsäljningen, ville de radikala nykteristerna gå ett steg längre och lagstiftningsvägen genomdriva ett allmänt rusdrycksförbud via det lokala vetot. Tanken med det lokala vetot var att varje svensk kommun skulle få genomföra egna allmänna folk-omröstningar, om ett lokalt/kommunalt alkoholförsäljningsförbud.Efterrösträttsreformen 1907/09 och "det stora nykterhetsvalet 1911" kom nykteristerna att dominera riksdagens andra kammare, vilket ledde till att ministären under Karl Staaf tillsatte en nykterhetskommitté.
Kostnader vid reparation av vattenläckor i Linköpings kommun
För att minska framtida problem med läckor på våra ledningsnät är det viktigt att man förnyar dessa. Planeringen av denna förnyelse kallas för förnyelseplanering. En metod i förnyelseplaneringen är så kallad ?riskbaserad förnyelseplanering?. Denna metod syftar till att hitta de ledningar som innebär störst risk.
Hur tolkas Warden?
John A. Warden III är en av vår tids mest inflytelserika luftmaktsteoretiker och Wardens teori är vida omskriven och ligger till grund för flertalet undersökningar. Warden redogör själv för att teorin inte skall ses som en mall utan att det snarare är generella idéer och riktlinjer. Det gör att teorin går att applicera på många olika fall men det lämnar också utrymme för tolkning. Syftet med denna uppsatts är att undersöka ifall allmängiltigheten i Wardens teori gör att teorin tolkas olika.
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.
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.
