Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water. The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the Growth and number of earthworms (this was evaluated after harvesting). The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture. Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied with 0.8 L per week.

A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning. In this study the distribution of the biomass within lodgepole pine trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.

Porcine circovirus type 2 (PCV2) is a common virus present in most parts of the world. PCV2 has been pointed out as the major causative agent to post weaning multisystemic wasting syndrome (PMWS) that affects pigs after weaning. The clinical symptoms of PMWS are impaired Growth, diarrhoea, respiratory problems and increased mortality. At autopsy enlarged lymph nodes with depletion of lymphocytes are commonly found. Since 1991 PMWS has spread all over the world and was first described among Swedish pigs in 2003. Although PCV2 is widespread, only some pigs develop PCV2-related diseases. Why this is and what other factors that are required in order for the disease to develop is yet unknown. The main theories involve other infections, for example PRRS, and management issues but also genetic differences between pigs and/or virus strains have been suggested.

Under det senaste decenniet har CSR blivit ett alltmer vedertaget begrepp, både inomföretagssektorn men också i samhället. CSR agerar idag verktyg för främjandet av hållbarutveckling och dess allt mer framträdande roll på marknaden tillsammans med företags behovav att förhålla sig till de marknadsanpassade förändringar som sker. Det har skapat ett behovav att företag implementerar, men också förstår vikten av att inneha att engagemang församhällsansvar. Uppsatsen ger en bred teoretisk referensram kring CSRs främsta grundpelarevilka beskrivs ur ett socialt, ekonomiskt och miljömässigt perspektiv där varje område är likaviktigt för ett lyckat CSR-arbete. Idag råder det mindre forskning om CSR inom SMEs, änvad det gör i multinationella företag.

Working as a veterinary nurse includes advising animal owners, helping them to make discisions through well-based facts and experience. Preemptive spaying of the healthy bitch brings many advantages and disadvantages. It leads to cessation of gonadal hormone production, and how the exact extent the surgery affects the dog is not yet fully understood. The sex hormones mainly control the reproductive system, but receptors of these hormones are found in many tissues of the body, and have complex relationships with other hormone systems. Spaying decreases the metabolism although the bitch gets an increased appetite, which enhance the risk of obesity, unless the owner restricts food intake.

Unga tillväxtföretag är svåra att värdera då tillgången till information är bristfällig. En potentiell investerare måste därmed uppskatta det unga tillväxtföretagets framtida utveckling då trender inte kan spåras i historisk data. Osäkerhetsfaktorn, såväl som den höga risken för misslyckande, måste således vägas in. Syftet med uppsatsen är att undersöka hur värderingen av unga tillväxtföretag går till i praktiken samt se hur risk och irrationalitet hanteras i processen. Vårt delsyfte är även att urskilja de faktorer som styr priset på ägarandelen.Vi har valt en kvalitativ ansats för att besvara vår frågeställning och för att få en djupare förståelse för de faktorer som inverkar på värderingen samt få en inblick i det mänskliga beteendet i investeringsprocessen.

Bakgrund: Idag är det inte enbart stora och internationellt etablerade företag som verkar globalt. Fler och fler små och medelstora företag internationaliseras och är numera av stor betydelse för tillväxten i många länder. Dessa företag har visat förmåga att etablera sig internationellt, trots att tillgången till framförallt finansiella resurser kan tyckas begränsa deras internationaliseringsprocess. Snabbväxande företag finns inom alla sektorer, men givetvis finns en förhållandevis större andel tillväxtföretag i branscher och sektorer där marknaden och efterfrågan växer snabbt. Roxtec AB är ett snabbväxande industriföretag som vänder sig till industriella köpare inom tre stora sektorer, telekom, marin & offshore och industri.

Syftet med denna studie är att teoretiskt pröva att integrera en etablerad metod för personlig utveckling, The Skilled Helper, med metoden Dynamisk Pedagogik och skapa en ny metod för en specifik tillämpning, personlig utveckling av ledare.Integrationen görs med hjälp av en etablerad metametod för metodutveckling. De bägge ingående metoderna värderas enligt fastställda kriterier. Samma kriterier används sedan för att värdera den nya metod som designas. Med detta har studien uppnått en jämförbarhet mellan de tre metoderna avseende parametrar som är centrala och relevanta för metoder och metodskapande.Studien skall besvara en rad olika frågeställningar såsom: Går det att skapa en integrerad ny metod förpersonlig utveckling baserat på av två befintliga metoder: The Skilled Helper och Dynamisk Pedagogik? Vad händer när man integrerar dem? Blir det konflikter eller synergieffekter mellan de bägge metoderna? Vad är kvar av Dynamisk Pedagogik? Den nya metoden som skapas, faller den inom ramen för etablerad ledarutveckling? Kan den kallas för en metod för ledarutveckling?Resultatet visar att metodintegrationen gick att genomföra då det förelåg en tillräckligt god grundläggande förenlighet mellan de två ursprungsmetoderna på en rad nyckelområden.

Summary Title: Taxes and Human Capital as Determinants of Foreign Direct Investment in EU: The role of Most Favoured Nation treatmentAuthor: Andreas HelmerssonSupervisors: Cecilé Brokelind and Rikard LarssonProblem discussion and problem Formulation: The recent year?s rapid increase in foreign direct investment (FDI) is a clear indication of increasing globalisation. In order to stay competitive companies must take advantage of talented people, new technology and new markets around the world. Not only companies but also countries and regions, such as EU, need to take advantage of globalisation and the advantages that come with the increase in FDI around the world. Studies have shown that FDI does not only make companies more competitive but it also stimulates the economic Growth of the region where the FDI takes place.

Title: Valuing Real Estate FCFE and interest coverage under macroeconomic uncertainty with scenario analysisAuthors: Marcus Ewerstrand, Jakob MattssonAdvisor: Gert SandahlBackground and problem: After the collapse in the Swedish economy in the beginning of the 1990-ties, the company Secerum was launched. Securums objective was to handle unsecured credits from Nordbanken by transferring a large portfolio of properties and to setup a number of companies who would be in charge for the prospects of these assets. One company that was established during this remarkable period was Castellum, in the year of 1994. After a successful process of raising capital to its development of corporate strategies and formation of several affiliated companies which operates locally, Castellum was publish on the Stockholm stock exchange 1997/1998. Now, thirteen years later after its establishment, the credit crunch in the US.

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

The purpose of this thesis is to analyze how the ongoing controversy surrounding the Internet, the phenomena of digitalization and file sharing will affect the music industry in the form of the ?big five? labels. Furthermore the thesis aims to present a recipe of strategies for the companies? survival by studying their situation through a theoretical perspective in conjunction with a comparative analysis with industries facing the digitalization challenge. The theoretical contribution lies in the strategic perspective at an industry level.

A shorter dry period length has in studies abroad showed some positive effects among high yielding dairy cows. Among other things it has been suggested that the periparturient metabolic stress becomes lower, that the fertility is improved and dry off becomes gentler for the udder, due to a lower milk yield. The milk yield is generally reduced during the first period after calving, especially among primiparous cows. The aim of this master thesis was to investigate how Swedish cows were affected by a shortened dry period, regarding milk yield, metabolism, health, body condition and body weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined.

This study is a value chain analysis for timber in East Africa. It was commissioned by Vi Agroforestry, a nongovernmental organisation registered in Kenya, Rwanda, Uganda and Tanzania engaged in a rural development program that involves promoting tree planting and enterprise development (Vi Agroforestry, 2012). The purpose of the study was to identify and describe common value chains for timber in the countries where Vi Agroforestry operated. Value chain is a concept and a framework describing how to structure information regarding activities included in satisfying a certain customer need, e.g. procurement, logistics, transactions, production and marketing.

Title: Music-esthetical productions in the educational work - a case study of the Allvar Gullstrand highschool.Problem: A problem associated with working with project- and thematic studies which result in esthetical productions is that it often demands extra effort and time beyond the schedule to carry the production through. There are no instructions saying that schools are to work with this kind of arrangements, but nevertheless it occurs in most schools, however in a different extent, quality and form. Purpose: The purpose of my study is to elucidate possibilities and limitations in different methods of work and structures, and also examine what motives the teachers and the school management have for working with a music-esthetical production as a goal. Method: I have done a qualitative case study of a Swedish upper secondary school where I interviewed four teachers and one principal, to get a view of reality and examine how teachers with different background look at, and in reality behave in, the work with music-esthetical productions in the education. Conclusions: What I have concluded in this case study is the importance of having a clear goal and that the project works are considered to create meaning and personal Growth.
