Detta examensarbete har utförts på uppdrag av Johan Lundberg AB som har haft ett behov av att det tas fram en guide vid åtgärder av vattenledningar. Åtgärder kan innebära nyläggning, utbyte eller renovering av en vattenledning. Syftet med rapporten är att ta reda på om ett visst material eller metod kan användas till vattenledningar, få fram för- och nackdelar med dessa material och metoder, både för installationsfasen och för driftsfasen. Detta görs ur ett långsiktigt tekniskt, ekonomiskt och miljömässigt perspektiv. Rapporten innehåller en faktadel med tänkbara material och schaktfria metoder och sju stycken intervjuer med ledningsägare har genomförts och en sammanställning av dessa intervjuer presenteras i kapitel 5.3.

Ronneby Miljö- och hälsoskyddskontor ville genom undersökningen få information om nitrathalter ienskilda dricksvattenbrunnar inom kommunen, med bakgrund av den nya miljökvalitetsnormen.Riktvärdet för nitrat är 50 mg/l. Halter som överstiger detta bör inte ges till barn under ett års ålder pågrund av risk för methemoglobinemi. Jämförelsen skulle ske mellan områden präglade av jordbrukrespektive skogsbruk, samt mellan grävda och borrade brunnar. Jämförelsen skulle även ske över tiden,mellan 1975-1990 till 2005. Urvalet av provtagningspunkter baserades på en sammanställning frånbefintligt arkiv samt efter en annons i dagspressen.

The purpose of this masters´ thesis is to examine the attitudes of public librarians towards easy-to-read literature and see whether a connection between these attitudes and accessibility can be made. The study has been performed with a qualitative approach and consists of four depth interviews with emphasis on how librarians relate to and experience easy-to-read literature and its´ users. As complement to the depth interviews, two micro interviews were made. The study can be seen as a follow up to a survey I made 2005, commissioned by The centre for Easy- to-Read. As analytical tools the cultural sociological theories of Pierre Bourdieu, with his concepts field, cultural capital and habitus, have been used.

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

The purpose of this essay was to find out how violin students apprehend their tuition and if it is possible to achieve good results without negative comparison or competition.The examination is based on eight in-depth interviews with violin students between 8 and19 years of age. All of the students had a strong will to develop and to feel satisfied with their achievements. Almost all of them agree that some degree of comparison and competition between violin students does exist. Although some of the students had seen negative sides of such competition, they agree on comparison as a good thing as long as it´s positive..

Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.

The study aims to investigate the impact of industrialised homebuilding in the creation of the aestheticproperties of the dwelling architecture.The concepts of industrialised homebuilding and the aesthetic properties of the dwelling architecture aredefined by previously developed models. In these models, industrialised homebuilding is described byeight characteristic areas. The aesthetic properties of the dwelling architecture are described by sevenaesthetic qualities.The study was conducted as a qualitative study, and in-depth interviews were conducted. The companyJM AB is the analysed unit that the author of this report has chosen to study. JM employees and by JMhiredarchitects were interviewed.The report concludes that characteristic area planning and control of processes are considered to havepositive impact on the aesthetic qualities if the process is designed in such a way that the creations ofthese are admitted.

In this thesis we propose a conceptual plan for thedevelopment of an Agroforestry Training Centre (ATC)in Musoma, Tanzania. The aim is to make a proposalto support peasant education in agroforestry. How canan ATC in Musoma be developed into a stimulatingand educational park suitable for teaching agroforestrymethods to peasant farmers and other potential users?To answer that a field study was conducted to investigatehow our client Vi Agroforestry Programme (Vi) and thetarget groups of the client can benefit from the site.The thesis begins with a short explanation of thecontext, in which the ATC plays a part followed by amethodology chapter. Next are three chapters presentedwhich introduce the reader to the research conductedbefore starting the proposal, these include: results ofliterature studies, study of precedents, and results of fieldstudy.

Music production software has a strong tradition of two-dimensional graphical user interface (GUI), in which the time line is represented as a flat composition either horizontally (from left to right) or vertically (from top to bottom). In my degree work titled Sequi, I approach music composition from a different angle. Instead of a two-dimensional time line with only two possibly ways of progression (forward or backward) I constructed a three-dimensional GUI with the maximum of four different ways of progression from any given point in a composition. The height axis is used to describe time-intervals (the time between downbeats) and the wide and depth axes are used to describe progression from one sound to another..

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

1 januari, 2004 infördes den nya revisionsstandarden (RS) som är en översättning av ISA, med hänsyn tagen till svensk lagstiftning. RS innebär flertalet nyheter vid genomförandet av revision. Bland annat har revisorns roll förändrats genom att revisorn numera skall granska och uttala sig om fler förhållanden än tidigare.Syftet med denna uppsats är att redogöra för revisorers och företagares syn på införandet av revisionsstandarden. Detta görs i form av en fallstudie med koncentration på tre utvalda RS (RS 402, 501, 570). Öhrlings Price Water House Coopers är representant för revisionsperspektivet och Vattenfall samt E.ON är representanter för företagsperspektivet.

Idag spolar den stora majoriteten av alla invånare i Sverige med dricksvattnen i toaletten. Spolning med regnvatten i WC är något som på flera håll i världen används flitigt främst i områden med någon slags vattenbrist. Men i Sverige har regnanvändande anläggningars popularitet inte riktigt slagit igenom ännu. Orsaken till detta kan härledas till flera faktorer. De viktigaste och de som påverkar mest är; den goda tillgången och således låga priset på dricksvatten i Sverige, samt begränsad konkurrens bland företag och återförsäljare vilket ger ett högt investeringspris på regnanvändande anläggningar för konsumenten. Fokus i detta examensarbete ligger på att göra en grundläggande analys av regnvatten och möjligheterna att genom en regnanvändande anläggning kunna använda regnvatten istället för dricksvatten för att spola i toaletten med. Tillvägagångssättet har varit att genom en studie av olika källor sammanställa information relevant till ämnet regnvatten och regnvattenanvändning till WCspolning, följt av en analys och jämförelse av hur ekonomiskt hållbar en regnanvändande anläggning i ett standardhus beläget i Malmö är, i förhållande till samma standardhus med en traditionell dricksvattenförsörjning för WC-spolning. Resultatet av analysen visar tydligt att en regnvattenanvändande anläggning i fallet med standardhuset i dagsläget inte går att rättfärdiga ur ekonomisk synpunkt, men även att det finns möjlighet till en realistisk ekonomisk förtjänst i andra byggnader eller i framtiden..

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.

Environmental objective 17: Sustainable consumption - An attempt to integrate the global impact of the Swedish consumption with the environmental objectives system The aim of this report was to integrate the global impact of the Swedish consumption withthe environmental objectives system through presenting a suggestion for a seventeenth environmental objective ? Sustainable consumption. How the Swedish consumption pressures the global environment and methods to measure the affects was investigated. The pressure was divided into five main fields: climate, air, water, land and chemicals. The impacton humans and the biodiversity was also discussed, as well as differences between how men and women affect the environment and get affected when the environment changes.
