The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.

This essay analyzes the market for entertainment software by identifying and explain the products typical properties, in addition i clarifies the behavior of consumers and producers. One of the most important property related to software is the ease with which it can be reproduced. When such reproduction is done illicit it´s called piracy. The software industry often claims that piracy leads to big losses for the companies as well as in welfare, the essay clarifies that this doesn´t has to be the case. On the contrary the possibility to cheap production and distribution may lead to an increased welfare.

Nature is in many ways considered a source to both physical and mental health among people. Trends in today?s society reveal that children become more distanced to nature. Seen from the perspective of sustainable development this trend is considered crucial: it is of importance that children in their early ages experience nature positively in order to develop a dedication towards environmental issues as adults.The purpose of this study is to investigate how teachers use outdoor learning as an educational tool. Research data were collected through a series of interviews.

In Sweden today many municipalities and sport clubs chooses to build artificial turfs becauseof the increased period of using the turfs during the year and less maintenance requirementsthan for natural grass fields. What could be problematic with artificial turfs is the rubbergranules used as infill material in the turf matt. The rubber granules are often made fromrecycled tires, which may contain for the human health and the environment, harmful substances.This was the reason why the Swedish Chemicals Agency commissioned a statusreport in 2006 which, among other things, concluded that the environmental and health risksassociated with granules made from recycled tiers in artificial turf fields were small, but thatthere could be a local environmental hazard. The purpose and objective of the risk assessmentwas to identify how artificial turf plans granules can affect recipients in the area closeto the pitches and provide input to reduce the spread of metals and substances harmful forboth human health and the surrounding environment. The work was divided into three parts:(1) the construction of artificial turf pitches and their material content, the spread of granulatesoutside the fields and disposal of artificial turf pitches.

Viktiga aspekter av klimatförändringar som diskuteras är informanternas syn på människans inverkan på klimatet, fördelningen av ansvar och viljan till förändringar och uppoffringar..

There are today large amounts of contaminated sediments in the Baltic Sea. These contaminants are the result of many years industrial activity where the contaminants have not been taken care of and just released out in the water. When ports want to dredge in their fairways and harbor areas the contaminated sediments need to be considered since they are a environmental risk. The development in this area has been slow and new techniques have just recently made its way into dredging operations in the Baltic Sea region. As a result of this there are no clear methods for implementing new techniques today.

Denna kvalitativ intervjustudie, söker en förståelse kring fenomenet sex som självskadebeteende. Självskadebeteende har studerats och definierats, men sex som ett självskadebeteende är inte inkluderat som ett begrepp i dessa vetenskapliga studier (Zetterqvist, 2014; Nock, 2014; Klonsky 2009). Däremot har psykologer, organisationer och andra professionella tolkat och definierat fenomenet som att det existerar (Sjöström, 2012; Landgren 2015; Jonsson och Mattson, 2013; Tjejouren 2015; MUCF, 2013). Genom intervjuer med tre olika personer som kommer i kontakt med sex som självskadebeteende, kombinerat med tidigare forskning, visar denna studie att sex kan användas som självskadebeteende och att det görs i syfte att hantera (coping) ångest och andra negativa känslor. Tidigare trauman och/eller en dysfunktionell familjedynamik kan leda till att en individ utvecklar icke fungerande strategier för att hantera potentiella dåliga känslor. Individerna vänder sig till sexuella destruktiva beteenden som en affektregleringstrategi.

Konsumentbeteende handlar om när, varför, hur och var människor gör ett inköp av en vissprodukt. Konsumenternas demografiska profiler är ett viktigt område inomkonsumentbeteende. När det kommer till frågan om shopping så förknippas ordet i stort settmed kvinnor. Samtidigt beskrivs ofta manligt konsumentbeteende från ett traditionelltperspektiv och skiljer sig från det kvinnliga köpbeteendet. De traditionella stereotyperna förmanligt konsumentbeteende är att män är mer benägna att ta risker när de handlar eftersom deinte brukar fråga personalen om hjälp eller åsikt, de jämför inte olika alternativ med varandra,de brukar inte planerar sina inköp, de är inte villiga att handla i grupp och är ?rädda? för atthandla i kvinnliga butiker.Eftersom könsrollerna kan ändras över tid är det viktigt att inom marknadsföring undersökakring dessa ämnen och inte ta de stereotypa könsrollerna förgivet.

The crucial factor for successful municipal climate work is that there are driving forces. Most importantly is that the senior officials and politicians in the municipality are dedicated to the cause considering that they have the power to influence and make a change. Besides proactive and committed individuals, it is necessary that the work is organized and anchored by clear and concrete documents and control systems. It is also important that the work is continuously monitored and evaluated. To collaborate with other municipalities, authorities or participate in various networks is another factor contributing to the improved climate work in the form of exchange of information, knowledge and experience.A major driving force for municipalities to improve themselves is the distribution of state aid and grants.

On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).

Eco certification of small housesTo construct an environmental friendly building and show that as a company you care for the environment, is presently very attractive in the Swedish real estate market.This degree thesis covers the environmental certification called ?Svanenmärkning? the Swan, witch is the Swedish equivalent to the European standard ?the EU Flower?. It is concentrated on the certification process in small houses that the Swedish institute of standard, SIS, has presented. We have worked together with the company Faluhus witch is a Swedish producer of small family houses.Faluhus is located in the town of Borlänge, Dalarna and has produced family houses since the 1950:s. They have a great heritage born in the old Swedish mining culture, with great wooden mansions and country homes.

The population growth and urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.

Background: Climate changes are a growing concern all over the world today. In June year 2006 the European Union accepted a new strategy for the Unions work against a sustainable development. The concept of taking consideration to all the aspects of an organisations/a company's activity is something that have been in focus during later years. Social and ethical aspects are in focus and questions regarding these aspects are more commonly included in the companies yearly reporting. A sustainability report is characterised by that it takes into account not only environmental aspects, like ordinary environmental reports, but also social and ethical aspects of a company's activity with it's surroundings.

Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.
