The thick shelled river mussel (Unio crassus) has a fragmented distribution in southern Sweden. It is a threatened and protected species. In both the Swedish red list and the IUCN Red List of Threatened Species Unio crassus is classified as Endangered (EN). Causes for this classification are for instance differentiated bottom substrate and deterioration in water quality. In this study, habitat preferences of Unio crassus were investigated to assist in future restoration work.

Studiens huvudsakliga syfte är att få kunskap kring om och hur elever i skolår 9 stimuleras till reflektion i matematikundervisningen. Den tidigare forskning som presenteras i litteraturgenomgången visar på reflektionens betydelse i lärprocessen och ger riktlinjer för vilka aktiviteter som uppmanar till respektive hämmar elevers reflektion. Genom en kvalitativ fallstudie, med i huvudsak lektionsobservationer som utgångspunkt och med efterföljande lärarintervjuer som stöd, har syftet uppnåtts genom att kartlägga den aktivitet som förekommer i praktiken. Undervisningsaktiviteter som kan uppvisa en positiv respektive negativ effekt på elevers möjlighet till reflektion har vid bearbetning och analys av materialet kunnat urskiljas. Resultatet visar att trots att lärare är positivt inställda till metakognition och ett reflekterande arbetssätt förekommer endast i vissa fall tillfällen då eleven stimuleras till reflektion och denna får ske.

The purpose of this essay is to explore how social media affect the political orientation and commitment of youths. Three scientific questions highlight the purpose from different angles. The didactic perspective is discussed in the initial and closing discussion, and is analyzed in the corresponding chapter. Two methods are involved in the study; one survey and one interview with a focus group. The survey had a total of 98 respondents from four different classes, all in the first grade of upper secondary school.

EU law is superior to Swedish domestic law, and it is on Sweden's responsibility to implement the COJ judgments so that it becomes compatible with EU law. The advantage of the Union being superior is the internal market given the member states.However, problems arise when the Swedish legislature goes further in its interpretation of EU law. Restrictions can be imposed but it must be considered to be strongly motivated so the restriction outweighs the need to maintain the freedoms granted by EU law. In Cadbury Schweppes, the court states that restrictions on freedom of establishment may be done to counter artificial arrangements whose sole purpose is to evade the national tax. Its further stated that an artificial arrangement does not exist in those cases there is a real business, even through the establishment in the low-taxing country is economically justified. The Swedish CFC rules states that the general rule is that if an establishment in a country within the EEA, which have lower corporate tax than 55% of the Swedish tax, the shareholder of this company is taxed on its current share in Sweden. The outcome of Cadbury Schweppes has not been made into a general rule, it became the exception. In addition to that in Sweden it is presumed that the company is an artificial arrangement that expressly are prohibited by the EUD, as well been implemented to supplement the rule, where the Swedish legislature changes the meaning of the term granted by the appeal. The Swedish legislature has amended the original economically motivated establishment, to be commercially motivated. The term is undefined, but applicable elsewhere in the Incometaxlaw and from this one can find that, for an establishment to be considered as commercially motivated the decisions to establish should be taken to promote normal profit-making enterprises based upon commercially motivated decisions..

Syftet med vårt examensarbete är att skapa ett informationsmaterial för nyinflyttade i Västerås kommun som så många som möjligt ska kunna ta del av. Vårt mål är att både lässvaga och lässtarka människor ska känna sig lika betydelsefulla när de läser informationsmaterialet. Vår forskningsfråga är därför: Går det att kombinera principerna för informationsdesign och principerna för lättläst för att nå både en lässvag och en lässtark grupp så att båda känner sig lika viktiga och tar till sig budskapet? Och om det går, hur kan man då gå tillväga?Vår uppdragsgivare är Centrum för lättläst som arbetar med att göra information tillgänglig för dem som har svårt att läsa. De behöver ett utprovat referensmaterial av ett lättillgängligt informationsmaterial som de kan visa upp för olika kommuner i sitt arbete mot ett tillgängligt samhälle.För att besvara vår forskningsfråga använder vi oss av litteraturstudier, samt kvalitativa och kvantitativa studier i form av utprovningar.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

A reforming trend is captured showing that countries are shifting from defined benefit pension systems towards defined contribution systems. The reforms have been justified through predictions that the defined benefit systems will not manage to provide good enough pensions to members in the future. The newer defined contribution pension plans often include individual financial accounts where individuals have the possibility to choose how a part of their pension savings should be invested. Sweden was early to introduce such a system, which at the moment provides more than 800 funds to choose from. The aim of this thesis is to capture the market risk associated with these individual investments and does so by using Monte Carlo simulations for six selected pension funds.

This report is a degree project performed at Freudenberg Household Products AB, (FHP). The degree project comprises measurement and analysis of the power net at FHP Basproduction. The content is divided between one theory-part, one document- part with measurements and also conclusions and a list of measures to be taken. During the project the purpose and restriction change from a quality investigation to only concentrate on harmonics and finding the reason why they exist, and also to find a solution to the problem with harmonics. The measurements shows that the power net contains harmonics of different order and intensity.

The translation of financial records of foreign subsidiaries gives rise to currency translation adjustments that affect total group equity. If unwanted, fluctuations in translation adjustments can be avoided using net investment hedges. This study aims to find the extent of net investment hedging in Sweden today and in a short historical perspective, and find explanations to varying levels of hedging and firms' decisions to hedge. Based on annual reports, we determine Swedish firms' net investment hedging policies and their level of hedging. The 32 largest companies listed on the Stockholm stock exchange in the years 1993, 2004, 2006, and 2009 are studied.

This thesis was conducted to assess how the privatization of Iran Air process managed in last efforts and how should it be in right way. It increases the knowledge about privatization in Iran and the need for it. Iran air as our case study is a flag-carrier airline company that is protected by government regulations and subsidies. We try to find the reasons for failure of privatization in Iran Air and their attempt on privatization.The method used to collect data was a qualitative methodology, consisting of semi-structured interviews with relevant managers, and knowledgeable professors and the official sites and press. In conclusion, we find that privatization is an important need for Iran Air Company and the main problems that are against Iran Air can be categorized to political, financial, and social.

The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production. Globally the quail production is very small, except in China where it is the second largest poultry industry. The production globally is small despite the quail's rapid growth, early sexual maturity and its high feed efficiency. The quail is also used as a laboratory animal and can be reared to be released in hunting areas.

A possible explanation for the inability of the governments of the world to implement necessary environmental policies is that they are worried of being punished by voters for implementing too forceful policies. But do voters actually punish governments that implement more stringent environmental policies? Few studies have explored this question directly. Parts of the literature on environmental policy and public opinion indicate that voters would predominantly reward governments that implement more stringent environmental policies, while other parts indicate that voters would predominantly punish them. It is also possible that voters punish governments that implement more stringent environmental policies in some contexts, but reward them in others.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.
