Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

The aim of this thesis is to examine the theoretical developments on social entrepreneurship. Our purpose is to create a better understanding of the phenomenon leading to new insights. We have categorized the knowledge of the concept into social economy, social ownership, social innovation and social missions. Drawing from our theoretical review we have chosen four empirical illustrations, Grameen Bank, Wikipedia, Basta Arbetskooperativ, Jörn Hälsogemenskap, and we have shown how these fit into the general description of the social entrepreneur. With help of our illustrations we show that it is complicated to pin point the core of social entrepreneurship as they each have separate structures, innovations, social missions and operate close to different sectors.

Purpose: To examine the governance mechanisms and the competence PE-firms adds to theirholding companies through an active ownership in order to create growth.Methodology: A qualitative study with interviews as its main source of data.Theoretical perspectives: Corporate governance and relevant theories within that subjectsuch as agent theory, board of directors and management. Previous research within the subjectwill also be presented.Empirical foundation: The empirical foundation consists of three conducted interviews anddata collected from the chosen PE-firms as well as six different holding companies.Conclusions: The governance mechanisms used in the PE-firms we have chosen are stronglyrelated to both theories within corporate governance as well as previous research on thesubject. The governance mechanisms being used are an explicit owners agenda and strategy, athorough acquisition process, usage of external competence, active ownership through theboard of directors and the insertion of incentive systems..

This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw materials have been evaluated and the advantages and disadvantages have been weighted against each other. The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed. The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.

Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

This essay discusses how Private Equity companies (PE companies) reason when evaluatingpotential companies to invest in through its investment criteria. Also methods they utilized toenhance companies value during their ownership period is treated.PE-companies invest in companies where they can see a good future development. Theintention is that through various methods to increase the company's value prior to divestment.In the UK and the U.S. in particular, the market for PE has long been great. In Sweden, insteadthe developments in the industry went a little slower.

The purpose of the study is to examine different situations and behaviors for students diagnosed with AD / HD and see if there are times where their diagnosis will be extra visible. This will ultimately see how and where these children may need support in their daily lives, and about the support they receive is relevant to their needs. Questions I intend to examine: Are there situations for students throughout the school day in which ADHD diagnosis becomes extra visible? If so, what situations? How is the diagnosis in these situations?It is estimated that about 3-6 percent of school children have AD/HD. It causes difficulties with concentration as well as impulse and activity control.

This dissertation aims to explore how an investment appraisal differs depending on if it is conducted by a municipal or a private real estate company. Municipal and private real estate companies are not performing on totally equal terms in the property market. A municipal company in Sweden has a public service mission. The consequence due to that mission is that they have limited yield potential but on the other hand the right to certain subsidies. They are also limited by the law of public purchasing (in Swedish: Lag om offentlig upphandling) in the investment process.

Good governance-begreppet introducerades av Världsbanken på slutet av 1980-talet som riktlinjer för hur en stat på bästa sätt skall organiseras och styras för att nå ekonomisk utveckling. Good governance-idealen innefattar bland annat öppenhet, transparens, rättsäkerhet och effektivitet, som sägs uppnås genom åtgärder som liberalisering och decentralisering. Banken har använt sig av konditionalitet då de ställt krav på anpassning till good governance till de länder som ansökt om utvecklingslån. Tidigare har good governance-kriterierna setts som absolut goda och tillämpbara i alla länder, i enlighet med ett best practice-synsätt. Många har kritiserat denna tillsynes förenklade världssyn och hävdat att agendan är alltför ambitiös och att banken bör ta hänsyn till mottagarländernas specifika kontexter för att nå bästa resultat.

Inköpsorganisationen har varit och är föremål för förändring. Vid sidan av denna förändring har Total Cost of Ownership (TCO) utvecklats. TCO sträcker sig bortom inköpspriset och innefattar enligt Degraeve et al. (2005a) alla kostnader relaterade till anskaffningen och kostnaderna användningen av en vara eller tjänst medför genom ett företags hela värdekedja. Utifrån en tillhandahållen förståelse för kostnaderna ett företag ådrar sig utifrån etablerade leverantörsrelationer kan TCO fördelaktigt användas vid valet av leverantörer och till att utvärdera prestandan av leverantörer.

Fusarium graminearum is one of the most important pathogens on cereals and causes major crop losses around the world. The most cultivated cereal in Sweden is winter wheat. F. graminearum produces both sexual and asexual spores for dispersal. Multiple factors affect the production of these spores.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

AbstractMy purpose with this study is to find out if it helps children who have diffuculties with their concentration if they get to practise their motor behaviour knowledge during their day at the school to promote their learning capacity. My purpose is also to find out how schools works with motor behaviour training. To get answers to my questions have I done interviews with four educationalists and I have also used books and internet sites. Motor behaviour is of importance to how children learn things in the school, without a well working motor children gets difficulties to sit still and to concentrate. The children may put their energy at the wrong things in the classroom, when the energy instead should be need to learning things.
