GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland
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.

Inventering av värmelager för kraftvärmesystem
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.
Global turism och hållbar utveckling : Svenska turisters uppfattningar om destinationspåverkan
De senaste åren har den internationella turismen ökat explosionsartat och den förväntas fortsätta öka på samma vis. Detta medför både positiv och negativ påverkan på destinationen och för lokalbefolkningen. För att turismen skall vara långsiktigt hållbar är det viktigt att inbegripa turisternas perspektiv på destinationspåverkan. Tidigare forskning har främst varit fokuserad på lokalbefolkningens syn på turismen, och därför behövs vidare forskning från turisternas synvinkel.Föreliggande uppsats har som syfte att undersöka hur svenska turister uppfattar destinationspåverkan inom de tre hållbarhetssfärerna ekonomi, sociokultur och ekologi. Vidare syftar uppsatsen till att undersöka eventuella skillnader i upplevelser mellan de två turistgrupperna massturister och alternativturister.Undersökningen har gjorts med hjälp av en enkätundersökning administrerad på Internet.
Käppalaverkets nuvarande och framtida rötningskapacitet : en studie i labskala
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.

Hur den nya revisionsstandarden upplevs av revisorer och företag - en fallstudie av Öhrlings Price Water House Coopers samt E.ON och Vattenfall
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.
WC-spolning med regnvatten
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..
Reviderad Svensk kod för bolagsstyrning: En studie av dess påverkan på svensk bolagsstyrning
The debate about questions concerning corporate governance has intensified in Sweden the last decade. From July 1th 2008, the Swedish Code for Corporate Governance was extended to comprise all Swedish companies listed on the OMX Nordic Exchange Stockholm. Our aim with this master thesis is to examine the effect of the Revised Code on Swedish corporate governance and in particular its contribution to creating value or costs. We do this through a qualitative study of 22 interviews with representatives for different interests. With our study, we have found that the Revised Code in several areas has had considerable influence on Swedish corporate governance.
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.
Miljömål 17: Hållbar konsumtion : Ett försök att integrera den svenska konsumtionens globala miljöpåverkan med miljömålssystemet
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.
Grundvattenmodellering i Badelundaåsen
Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.
Pre-spawning habitat selection of subarctic brown trout (Salmo trutta L.) in the river Vindelälven, Sweden
Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.
Finansiering av nystartade företag : En kvalitativ fallstudie om finansieringslösningar för entreprenörer utan erfarenhet som sträcker sig längre än tre år inom entreprenörskap och restaurangbranschen
This is a qualitative case study that aims to examine the small entrepreneur?s choice of financing solutions and their thoughts on various forms of financing. The authors have chosen to specifically examine entrepreneurs who do not have experience that stretches more than three years in entrepreneurship and the restaurant business. The study used three different companies in the restaurant business in Stockholm and semi-structured interviews were conducted with all owners of the company, corresponding to a total of six respondents. The study's findings show the relationship of entrepreneurs who believe that the experience of the industry and entrepreneurship is valuable also are more prone to giving away some ownership in exchange for a certain expertise and funding..
