The main purpose of this study is to provide marketers with basic guidelines on how brands can benefit from internet social networks such as MySpace, Facebook and Hi5.

Syftet med uppsatsen är att undersöka om en investerare kunnat uppnå en signifikant överavkastning genom att delta i nyemissioner hos företag noterade på Stockholmsbörsen mellan 1997-2008, samt hur denna avkastning påverkas av olika variabler. Uppsatsen har sin utgångspunkt i en buy and hold-studie, vars ansats är deduktiv. Vid datainsamling kommer en kvantitativ metod att används. Observerad avka

In this thesis I investigate the potential trade effects associated with three antidumping cases filed by the U.S. steel industry during the first decade of the 21st century. The analysis consists of a detailed case study, covering everything from the establishment of dumping margins to the final effects. The empirical results are consistent with expected effects, i.e. decreasing imports from targ

Abstract Aid-tying is considered costly and ineffective to recipient countries and it is estimated that costs increases by as much as 30 per cent due to its practice. The Paris Declaration on enhanced aid effectiveness suggested an end to tied aid. The purpose of this paper is to give a review of the development of aid-tying in the European countries in the last thirty years. It will also look at

The aim of the thesis is to examine if the efficient market hypothesis applies to the Swedish mutual fund market, and thereby determine whether actively managed funds in Sweden beat the market or not. In order to do so I constructed a Monte Carlo simulation of the Stockholm stock exchange that produced random portfolios following a set of investment constraints. A series of comparisons between the

A study of a sterilizing flow in a package is done. The study is done with the commercial code Fluent using Large Eddy Simulation and validated with both Laser Induced Fluorescence and Particle Image Velociometry. The velocity field is examined in several ways; with changes in grid size, inlet conditions and sub-grid scale models. The study showed that the most important parameter is the size and

With today’s growing awareness of human caused climate changes there is a big interest to replace fossil fuels with renewable fuel sources, such as biomass fuels. For power production biomass are traditionally combusted in small scale facilities which uses a steam cycle. The electrical efficiencies for such facilities are relatively low. By gasifying the solid biomass to syngas it can be used for

In this study a dynamic model of a solid oxide fuel cell system has been developed. The work has been conducted in cooperation with Modelon AB using the Modelica language and the Dymola modeling and simulation tool. Modelica is an equation based, object oriented modeling language, which promotes flexibility and reuse of code. The objective of the study is to investigate the suitability of the Mode

In this study the possibilities for a new steam boiler and a replacement of the old back pressure turbine at AAK Karlshamn are investigated. AAK is a company that refines vegetable oils and one of the factories is in the town Karlshamn in Sweden. At AAK Karlshamn process steam and electricity is generated in a cogeneration facility whit several boilers and a back pressure turbine. To continue whit

This thesis is a risk assessment of the risk related to ingestion of heavy metals via peaches irrigated with treated wastewater. The studied heavy metals were Cadmium (Cd), Lead (Pb), Zinc (Zn) and Cupper (Cu). The thesis is founded on a case study performed on a peach field in Ouardanine, Tunisia. Analysis of the heavy metal content in the treated wastewater used for irrigation was conducted as w

The aim of this project is to investigate whether scuba diving equipment can be made safer and more attractive for new divers. The thesis shows that most accidents occur because of poor equipment checks and misused equipment. This problem is the main concern of the thesis. The resulting product, 4° (Four Degrees), is a buoyancy compensating vest with a focus on safer diving, non-complex appearance
