Småvatten då och nu : en förändringsstudie av småvatten i Skåne och deras kväveretentionsförmåga

Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.

Testmetodik för vintertestning av el- och hybridfordon

With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

Gröna transportkorridorer

The economic development and competitiveness in Europe is heavily dependent on an efficient transport system. Movement of goods and people is essential for a competitive industry and successful trade. As a result of an intensified transport business, consumption of fossil fuels has increased dramatically. As a consequence, there are increased emissions of dangerous greenhouse gases. Transports are often mentioned as an area with high impact on the environment.

Uppföljning av familjehemsplaceringar: inte bara brandkårsutryckningar

The purpose of this essay was to examine how professional social workers work with follow up foster home placements. The study was based on qualitative interviews with ten professional social workers from different municipalities in Skåne in an attempt to answer the following questions:* What routines exist for the follow-up work with foster care?* What factors have an impact on how the follow-up is formed in the particular case?* How can the follow-up affect outcomes of the placement?* In what way could the work with follow-up foster home placements develop?The theories we chose to analyze our material from was the ecology of human development formed by Urie Bronfenbrenner and the theory of civil courage formed by Lennart Lundquist. The interviews were semi-structural which gave the respondents a chance to talk in a free way about the questions we presented.The result of the study showed that there is a difference in the way social workers form the follow-up work of foster care. The greatest difference is in whom the social workers include in their follow-up.

Balanced Scorecard identifieringens dolda dilemma

The use of balanced scorecards have spread explosively throughout the world during the last decade. This management tool have become very common in a vide spread variety of organisations on all continents. Many balanced scorecard fails though and scorecard theorists often blame the identification- and implementation process as they claim that these lay the foundation for the use of the tool. As my literature study shows, academic research on the area is rare. Particularly the effect on the implementation process from organisational dynamics and organisational structures needs further research.

Grön olja? - En fallstudie av ett oljebolags miljöprofilering

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

Storbankerna på den svenska bankmarknaden : Argument för och emot infrastruktursamarbetet enligt 19 § KL

The retail banking market in Sweden is highly concentrated and oligopolistic. This has been confirmed by numerous reports from different competition authorities within the EU, for example the Swedish competition authority. A considerably high number of different sorts of competition barriers has been pointed out in these reports. The competition barriers are mainly directed to the smaller banks and the potential competition. The retail banking market in Sweden is dominated by four major banks, which together has over 80 percent of all market shares.

Fördröjning och bortfall av nätverkskorrektioner : osäkerhetskällor för nätverks-RTK

Network RTK is a real-time technique for accurate positioning with Global Navigation Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be transferred seamlessly to the user in real time. Commonly the corrections are transferred via mobile phones. The Swedish National Land Survey operates a nationwide Network RTK service, where users can receive correction data via GSM or mobile Internet (GPRS).

Effekt av sederingsrutin och vikt på höftledsröntgen hos hund

The aim of the study was to investigate whether the sedation method had an effect on the screening result for hip dysplasia (HD). Another aspect considered was if the dog?s weight had an impact on the results. This study was a follow up on the results from an earlier study of sedation routines in Swedish dogs. The breeds included in this study were the same as in the earlier one; German shepherd, Bernese mountain dog, Boxer, Newfoundland, Rottweiler, Saint Bernard, Golden and Labrador Retriever.

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

Ett svenskt landskap i Australien : svenska kyrkan i Melbourne

As a Swedish landscape architecture student living in Australia for five years, I have often wondered if my memories and my associations with the landscape and the nature in Sweden, are the same as other Swedish people living in Melbourne. Most of the Swedish people who live here in Melbourne remember and associate Sweden?s nature and landscape with where they grew up or where they used to live. The plants that most of the Swedish people I asked missed from Sweden were associated to special feelings or activities. The general type of landscape people remember from Sweden is that of a landscape covered in forests, which you can walk freely through. With these memories as a foundation and with inspiration from the Swedish landscape architect Thorbjörn Anderson?s way of creating places, by letting a few strong changes play against the existing elements,2 but also with consideration of the climate and the severe shortage of water that is current in Melbourne, will I create a design concept for the garden surrounding the Swedish Church in Melbourne. A design concept that will generate memories and associations to Swedish landscapes..

Beräkning av energianvändning i svenska småhus

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.
