Does nuclear power plants affect house prices? : a hedonic price model of Forsmark nuclear power plant
Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.
Teoretisk och experimentell utvärdering av Lättelement AB:s takinfästning
Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.
VTA-aggregatet : En undersökning av driftegenskaper och funktion vid slowsteaming.
Turboaggregat med variabel geometri har länge funnit hos automobiler, men det dröjde ända tills 2008 innan det första dök upp på ett fartyg. Syftet med denna undersökning har varit att kontrollera om de fördelar som Man B&W hävdar att VTA-aggregatet skall ha stämmer, samt att undersöka om VTA-aggregatet kan lösa de problem som uppkommer i och med att man kör med reducerad fart, s.k. slowsteaming. För att undersöka detta har jag bedrivit litteraturstudie, med insamling av data mestadels från Internet.Resultatet av undersökningen visar på att ett VTA-aggregat kan minska bränsleförbrukningen och vissa emissioner vid reducerad fart jämfört med en konventionell turbo av samma storlek. Den minskade bränsleförbrukningen leder i sin tur till ekonomiska vinster.
Värdeförändring på butiksfastigheter och makroekonomiska variabler - en ekonometrisk studie av samvariation
The purpose of this Bachelor thesis in Economics at Lund University is to try to establish the correlation between the value change of retail real estate buildings in Sweden and macro economic variables. The principal method is the multiple regression model and it is used to estimate the basic model. The basic model is enhanced by estimating some 30 models and the result is two good models. The difference between the basic model and the two better models are small but important. In the lagged basic model, the same variables are used as in the basic model but with different time lags.
Welfare impairment of lambs around weaning. Play and other behaviour indicative of affective state
The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.
Omvänd aktiesplit : överlevnad eller kosmetik
The shareholder is supposed to be indifferent if one share costs 100 SEK, or 10 shares cost 10 SEK each. In an efficient market, shares should be valued directly to new expectations as a result of the announcement of the reverse split. We investigate whether abnormal returns incur surrounding reverse split and if owner structure change.One reason for the reverse share split is that most companies have plans to imple-ment other company?s specific events in order to survive rather than to change the price range to a more attractive level. We found a negative return in the ex-day at 8,1 per cent.

Varumärkesutvidgningar för Personliga varumärken vs. Företagsvarumärken - Same same, but different
Today, branding is not a phenomenon but rather a prerequisite for a brand to be able to both survive and grow stronger. During the last couple of years, personal branding has come to be an established term, just like corporate branding. With the growth of the social media and the thousands of ways to interact with each other personal brands face great competition. It is more difficult than ever to maintain a strong brand, partly because of this. There are several growth options for brands.
Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.
Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.
Kundrecensioner : ett sätt för researrangörer att marknadsföra sig
Tusentals budskap tävlar om konsumenters uppmärksamhet varje dag och det blir allt svårare för företag att kommunicera sina budskap till potentiella kunder. Användandet av kundrecensioner för teknik- och mediaprodukter har bevisats påverka försäljningen av dessa produkter positivt. Denna uppsats syftar till att ta reda på om kundrecensioner är ett bra marknadsföringsverktyg för resor, som är mer komplexa produkter än de som nämnts ovan. Frågan är om kundrecensioner kan hjälpa researrangörer att särskilja sig från konkurrenter samt hur recensionerna bäst utformas för att öka deras försäljning av resor. Det finns 187 svenska researrangörer som erbjuder paketresor till utländska destinationer. Denna studie inleds med en kartläggning av 37 av dessa researrangörer; de som har kundrecensioner på sina hemsidor.
WTO - spelarena för utvecklingsländer? En studie om avgörande faktorer för utvecklingsländers förmåga att implementera sina regimpreferenser
This Bachelor Thesis is entitled "WTO-spelarena för utvecklingsländer? En studie om avgörande faktorer för utvecklingsländers förmåga att implementera sina regimpreferenser". Through our empirical results in conjunction with realist theories, this Bachelor thesis attempts to answer the questions: (1) How does the decline in American power, the nature of existing institutional structure and Third World unity, influence the ability of developing countries to secure its preferred regimes? (2) What function do informal meetings in the WTO have? (3) How does access to informal meetings influence the ability of developing countries to secure its preferred regimes? The paper makes use of case studies from the Ministerial meetings in the Doha development round.The conclusion is that access to these meetings is an important variable to explain the extent to which the Third World can be able to secure its preferred regimes. The degree to which developing countries can secure their preferred regimes is therefore a function of four variables: the nature of existing institutional structures; Third World unity, the attitude and power of the United States and foremost access to informal meetings..

Akuta effekter av assisterade hopp på kvinnliga idrottares hoppförmåga
Vertical jumping ability is an essential skill in many sports. The aim of this study wasto investigate the acute effects of assisted jumps on subsequent countermovementjump (CMJ) performance by female athletes. Nine healthy, trained female subjectsvolunteered to participate in the study. In a randomized order, they performed oneregular warm up protocol before testing their CMJ baseline value, and one warm upprotocol with an addition of five assisted jumps at 30% body weight reduction beforeanother CMJ test. Elastic cords attached to an overhead pulley system and to aharness around the subjects' upper body were used to reduce the body weight.Significant improvements were noted in jump height, 2.3 cm (7%), positive forceimpulse, 4.7 Ns (2%), vertical take off velocity, 0.1 m/s (3%), countermovement time,0.1 s (12%) and breaking time, 0.1 s (14%), p.
Energieffektivisering av arbetsbodar på byggarbetsplatser
Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.
Ekonomisk frihet och nationers välstånd
This bachelor thesis examines the relation between countries? degree of economic freedom and their economic performance. Economic freedom as a concept is defined as the degree of market economy within a nation.The variable of measure that is used is the Frasier institute Economic freedom of the world index (EFI). The paper is built upon the Solow growth model and is extended by incorporation of additional variables; among which of course economic freedom. The study is performed through regression analysis, based on the neoclassical model both on rich countries, poor countries and on all investigated countries.Two investigations are performed: i) the impact from economic freedom on countries level of GDP per capita and ii) the impact from economic freedom on the growth rate in GDP per capita.The finding is that economic freedom can be seen as a relevant determinant of differences in GDP per capita growth rates between nations.
