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.

I am interested in humans, bodies, movements, directions and how they affect each other. How we move towards each other or away from each other, inside a home or outside. How we relate to each other and to what people say and do. Co-operations between people that occasionally, possibly, do not work; how certain relationships, like certain materials, can have various breaking-points; that materials can be laden with numerous preconceptions, for instance what they should be used for.Beginning from the perspective of a feminist commune, I have explored the concepts of family, belonging, and loneliness. I have interviewed, observed, photographed, and through living in the commune during shorter periods of time, I have taken part in their every-day life.

This essay examine the meaning produced around bodies and body fat in the queer community, but also in the surrounding straight community. The author has interviewed fat activists, and are using queertehory, to examine and analyze the relationship between body fat and the understanding and construction of sexuality and gender. The author concludes that even if norms around body shape and body fat are overlapping between the two contexts to some degree, they also differ. In the straight community, people with larger body shapes and sizes are punished, and encouraged to stay, or become, slim. However, in the queer community, ?fat? or bigger body sizes are not frowned upon in the same degree.

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

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..

Though death and mortality is an inevitable part of our lives it seems like both the society with its culture and the individual in some way repress death. This study was set to explore how and why the individual holds back thoughts on his/her own death and in which way society affect the individual?s repression of death-thoughts. Using a hermeneutic approach I have interviewed five informants about death and thoughts about death in everyday life. Also for the analysis of the empirical material a hermeneutic approach was used, and the works of Bauman, Giddens, Heidegger, Fromm and May served as a theoretical starting point.

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.

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.

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.

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

This Bachelors exam is about young adults and their use of Mobile Social Network System.The use of mobile social media has become more common in today?s society, ranging fromteenagers, the dominating internet users, to the elderly. The traditional purpose of use inmobile phones, the voice communication from one place to another, has in Sweden beendominated by text communication instead. Along with the development of Smartphones andthe mobile interface, the births of mobile social media have increased in the market.Reports have shown that of all the devices with the possibility to connect to social networks,the one kept closest to our bodies is the mobile phone. One of the advantages of using thephone for mobile social media is that you can easily and smoothly update whenever andwherever, within one arm?s reach.
