In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

From July 2005 on, the new Swedish Corporate Governance Code will be applied gradually by companies listed on the stock exchange or any authorized financial market in Sweden. The Code has been drawn up in order to clarify and to improve the self-regulation in Swedish companies. The need for codified self-regulation standards has been considered as urgent due to negative trends on the market such as the last few years? corporate scandals in domestic and international trade and industry. The sought-after consequence is to clarify the mission framework for corporate directors.Ch.

The goal of this thesis was to explore how real estate investment companies are affected by a weaker world economy. The reason to investigate this was that in the 90s in Sweden, the housing market crashed in conjunction with the bank collapse. Therefore I have looked at how the commercial real estate companies would be affected if we were to have a double dip recession, because it has been confirmed by Gyourko that commercial real estate market and the housing market tend to react in the same way on new fundamental information. This was examined through a sensitivity analysis, one investigated the effect of falling rent income and the second analysis looked at the effect of higher interest costs. I found that IAS 40 rule about unrealized profits of properties affected the results in a significant matter and therefore decided to include the regulation in my thesis.

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.

This thesis concerns agreements for the exchange of information relating to tax matters between Sweden and the previous tax havens Monaco and Liechtenstein. Monaco does not apply any tax on income or capital for individuals and Liechtenstein has strict bank secrecy, both aspects are supposed to be counteracted by similar agreements. The purpose is to investigate whether the entered agreements increases transparency and effective exchange of information in accordance with the OECD´s objectives in the area. Furthermore, is there any regulation in the agreements that can be seen as potentially loopholes to avoid the exchange of information and if so; may these loopholes be justified in any way?OECD believe that the tax havens favorable tax regulation is resulting in harmful tax competition and they identify lack of transparency and lack of effective exchange of information as the main reasons.

Sapa Heat Transfer is a company that produces aluminum heat-exchanger strips for the automotive industry. Sapa Heat Transfer wish to chart their emissions of carbon dioxide in order to meet future demands on carbon dioxide reporting. They also would like to examine the meaning of the term ?green electricity? which is marketed as carbon dioxide free, and the sort of electricity that they purchase. This report includes both direct (liquefied petroleum gas and diesel) and indirect (water, process-water, long distance heating, waste) emissions from their company.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

In this interview study I have examined eleven Swedish advertisers and professional communicators and their view of ethics in the advertising industry. The purpose of the study was to shed light on how they see their ethical responsibilites, as well as trying to understand how they reason in regard to ethics as a whole. The main research questions regard the distinction between business and economic responsibilities towards their clients and societal ethical responsibilities, which ethical questions are of importance to them, and how they believe the industry should be regulated.The theoretical framework of the study uses media ethics, social responsibility theory, media accountability theory, and stockholder and stakeholder theory as its base. The study was performed using a qualitative method through interviews and the interpretation of these. The results of the study finds that the consulted advertisers have set opinions of what they themselves would decline to work with for ethical reasons, and has also been able to identify five main categories of ethical issues that they attach great importance to.

ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.

The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.

According to the arm?s length principle, transactions between associated multinational en-terprises (MNE) shall be based on the same conditions as transactions between unrelated parties. This means that intra-group prices on cross-boarding transactions must be at arm?s length range and consistent with conditions in the open market. The arm?s length principle is expressed in article 9.1 of the OECD Model Tax Convention and Chapter 14 section 19 of the Swedish Income Tax Act.When transfer pricing between associated MNEs is not reflecting the arm?s length princi-ple, states face the possibility of losing tax revenue.

Alkoholberoende och missbruk är ett omfattande problem i såväl Sverige som i övriga delar av världen. Med tanke på de fysiska, psykiska och sociala konsekvenser som missbruket leder till för både missbrukaren, och människor i hans eller hennes omgivning, finns det all anledning att undersöka möjligheter för att åtgärda detta. Syftet med detta examensarbete är att kartlägga olika behandlingsmetoder och att med psykologiska teorier om mänskligt beteende som utgångspunkt komma fram till den behandling en alkoholberoende individ behöver. Resultaten visar på att såväl personlighetsfaktorer som det sociala sammanhang individen befinner sig i har betydelse för om han eller hon missbrukar alkohol eller inte. Den sociala miljön bidrar till stor del till en alkoholberoende individs identitet och beteende.
