The subscribers can use this mobile application to access information regarding their consumption, invoices and active subscriptions. The mobile application that was built consists of a GUI and a web API as middleman between the application and the database.                     .

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

In the following study I probe the social world of hard-rock music. By conducting interviews with four young male enthusiasts of this music I try to develop a general picture of this social world, as well as of the basic elements on which this particular subculture is constructed. The identity of a hard-rocker is based upon a number of factors beyond just a preference for that music. Throughout the interviews I encountered many implicit norms that one must followed in order to be able to see oneself as a true hard-rocker. I also found that from the respondents? perspective, the mainstream culture has, throughout the history of metal music, used various ways to counter the spreading of this genre.

A majority of Swedish consumers have a positive attitude towards organic production and the number of organic products on the market is increasing. Despite these positive trends, there are still relatively few consumers who choose to buy organic produced products. According to statistics, only 3% of the total sales of food consist of organic products. The aim with this essay is to understand what is needed, both from the grocery store and the consumer's point of view, to increase the consumption of organic food. Information has been collected partly through questionnaire with consumers and partly through analysis of sales statistics for a selected numbers of products. Then the empirical material have been analysed in the light of a combination of the Behavioural Perspective Model (Foxell, 1997) and Kotler's Four P:s (Kotler, 2002). Consumer's willingness to buy organic products is influenced by a number of different factors. One important thing is if the grocery store offers a behaviour setting that stimulates the consumers positive attitude and facilitates their possibilities to collect new information. Furthermore, the store needs to offer a broad and well-visualised selection of organic products.

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

Healthy calves are the foundation in order to run a profitable diary production. Being healthy as calf results in a better start in life and good growth is expected to follow. Within dairy production it becomes more common to rear calves in groups and feed them by an automatic milk feeder. The milk feeder enables for the calves in greater extent to ingest milk or milk replacer several times per day and they are also able to perform natural behaviors in greater extent. Group rearing of calves puts higher demands on the animal keepers to localize individual calves in the group pen, showing signs of illness.

The purpose of this study is to evaluate the real aggregated consumption and empirically determine its exogenous variables. A multiplicative analysis is done in the context of government stabilization policy to find out how policymakers can execute a stimulus package that will bring the best multiplicative effect to the economy The conclusion of the study is that real income, net financial assets and real-estate price index are all statistically significant. An effective expansive fiscal policy is a public-financed investment in the private sector. Coordination is going to be crucial when stimulus package is developed due to the fact that leakage in the form of imports will prevent the expected multiplicative effect..

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

The aim of this essay is to find out how students at Malmö University relate to moral responsibility in their private consumption. I am going to test moral theories in order to find out if researchers have a too moral starting point in comparison to everyday use. Through a critical research, free from valuation, I also aim to raise a discussion about moral responsibility which should lead to fair trade in the long run. My essay discusses the subject out of a Swedish city, Malmö - a place where many stores, cafés and restaurant are using moral responsibility as a step in their marketing. The results show that students are interested in morality but their financial conditions are their prior factor..

Recent statistic shows that about 28% of adolescents living in Stockholm drink alcohol at such a high level that their consumption counts as risky drinking. The correct term to use in this matter would be binge drinking adolescents.  In the more wealthy areas of Stockholm this group of binge drinking adolescents counts for as much as a third of the population. In contrast, the adolescents living in exposed areas do not drink nearly as much. Binge drinking adolescents in these areas only counts for 15%, nearly half as much as in the wealthy areas.In light of this the intentions of this study is to investigate which explanatory factors that can clarify the range-rated differences in binge drinking between adolescents in Stockholm.

Food consumption generates externalities such as carbon dioxide emissions, which contribute to global warming. The principal issue is that emissions are not covered by the "polluter pays principle". For this reason, new policy instruments need to be tested and implemented to correct the externalities. In food production, beef and dairy production has the largest environmental impact in terms of carbon emissions. As food is a necessity, simply reducing production will not solve the problem.

Listeriosis, which is caused by Listeria monocytogenes, is a rare food borne disease that primarily affects people whose immune system is weakened. These may be elderly people, pregnant women, new-born infants and individuals on immunosuppressive medication. The most common symptoms are meningitis, septikemia and abortion. The mortality is high, on average 20-30 %. In recent years the number of cases in Sweden has increased.

Turboaggregat med variabel geometri har länge funnit hos automobiler, men det dröjde ända tills 2008 innan det första dök upp på ett fartyg. Syftet med denna undersökning har varit att kontrollera om de fördelar som Man B&W hävdar att VTA-aggregatet skall ha stämmer, samt att undersöka om VTA-aggregatet kan lösa de problem som uppkommer i och med att man kör med reducerad fart, s.k. slowsteaming. För att undersöka detta har jag bedrivit litteraturstudie, med insamling av data mestadels från Internet.Resultatet av undersökningen visar på att ett VTA-aggregat kan minska bränsleförbrukningen och vissa emissioner vid reducerad fart jämfört med en konventionell turbo av samma storlek. Den minskade bränsleförbrukningen leder i sin tur till ekonomiska vinster.

Outdoor advertising is not very often discussed within city planning even though the commercial messages occupy much of public space. The advertising signs affects not only the physical environment but also social life. In this report I would like to acknowledge and question the presence of advertising in our everyday environment. Outdoor advertising is not a new phenomena, technical progress however, results constantly in new expansions in the environment. Today advertising occurs in all sorts of shapes in the cities, both as free standing signs and as signs attached to facades, incorporated in city furniture such as bus shelters and on vehicles moving along the city streets. Grouping advertising into two categories; local and national, reveals that the different categories have different impact on public space.
