This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.

The aim of this report is to create an easily accessible guide to basic hygiene, cleaning and disinfection within the small animal practice. It is based on a literature study, using mainly research from the public health sector, due to the lack of relevant scientific reports within the veterinary field. To prevent the spread of infectious diseases it is important that the staff understands the importance of basic hygiene. Hand hygiene and disinfection and cleaning with water and detergent combined are the most important routines to prevent spreading of disease. In conclusion the differences between the veterinary and the public health sector are small, but some basic differences exist due to the nature of the patient?s needs.

The use of entertainment in various kinds of business events has recently increased in popularity among Swedish firms. Often, stand-up comedians are hired to entertain the employees or customers during these happenings. Generally, the firm invests a considerable amount of money in this service and is furthermore willing to pay a premium for a famous comedian. Although the market for this type of service is fairly large, the knowledge of the motives behind the investments is yet limited.A grounded theory study is carried out exploring the purpose of the entertainment as well as the rationales behind the preference for a famous comedian over an unknown. Two general types of contexts (internal and external) are identified and a number of objectives related to each type are distinguished.

This study intends to explain the problem with the implementation of new Swedish accounting rules called K2. The rules are simplifications of the general accounting rules and the purpose is to make it easier for small companies to account. Despite this, few small companies have adopted the rules. This study seeks to explain the weak response to the K2-rules using institutional theory.The research objects of this study are Burger King, McDonald?s and two audits and accountants.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

The purpose is also to try to examine whether there is a relation between the selected risk, return and fees.

Sammanfattning Studien ämnar ta reda på vilken teori som är mest applicerbar, den Ricardiansak ekvivalensen eller den klassiska Keynesianska teorin.  Studien är kvalitativ och bygger på en enkätstudie riktad mot studenter där de tillfrågade svarat på hur deras inställning till vissa frågor är. Resultatet analyserades genom en kvalitativ analys samt jämfördes med tidigare rapporter inom ämnet för att se om resultaten ligger i gemensam linje. Utifrån resultaten antyder att den Ricardiansak teorin inte efterföljs, något som även stöds av tidigare rapporter inom ämnet.  Statsskulden har ingen påverkan på studenternas konsumtionsbenägenhet utifrån undersökningens resultat..

Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.

This thesis is dealing with the programs of control regarding deceit and quality assurance within the Swedish social insurance administration in Skåne, the years 2002-2005. In 2005 the Swedish National Audit Office released a report regarding the lack of measures towards deceit and fraud, and the lack of quality in the data for decision making within the administration. The questions to be addressed are why the administration does not make up to the demands regarding quality and measures towards deceit that the government and The National Audit Office demands. The main source for data has been interviews with workers within the administration and annual reports from public authorities. To understand and be able to explain the problems within the administration the theory by Michael Lipsky regarding street-level bureaucrats is used.

The report is a result of a bachelor thesis at the department of business administration, School of Business, Economics and Law, Gothenburg University, spring term 2008. The study examines the potential return of Swedish Venture Capital firms? Cleantech investments, carried out in 2006 and 2007, compared to the return on their other investments.The study has identified a number of factors affecting the return. These have been classified within three areas: the characteristics of the Venture Capital investment, the characteristics of the Venture Capital firm and the market potential for Cleantech. The impacts on potential return for these factors are investigated by means of an interview survey with 18 Swedish Venture Capital firm covering 45 investments in Cleantech.Our research indicates a worse potential return on Cleantech investments compared to other investments.

Syftet med uppsatsen är att, i ett kort och längre tidsperspektiv, undersöka effekten, i form av överavkastning, på aktiekursen av rekommendationer gjorda under 2005 och 2006 av de högst rankade analytikerhusen i Sverige. Undersökningen genomförs för en tiodagarsperiod omgivande rekommendationsdagen samt för en, tre respektive sex månader. Syftet är också att studera huruvida överavkastningarna skiljer sig åt mellan den svenska börsens Large-Cap lista kontra Mid- och Small-cap listor. Studien visar att rekommendationer utgivna av analytikerhusen ger effekt på marknaden, mätt som överavkastning, på kort sikt. Effekten skiljer sig åt beroende på vilken lista bolaget är noterat på..

Revisionsberättelsen är ett viktigt verktygför kommunikationen mellan revisorerna och in­tressenterna. Dagensrevisionsberättelse är väldigt standardiserad och i samtliga delar finns detförslag till exakta formuleringar. Enligt tidigare forskning finns det enintressekonflikt mellan intressenterna och revisorerna. Denna konflikt handlarom att intressenterna vill ut­vidga informationsinnehållet irevisionsberättelsen vilket revisorerna är kritiska till eftersom detta skulleinnebära mer ansvar och mer att stå till svars för. För att lösa denna konflikthar revisionsberättelsen debatterats flitigt och i en debatt diskuteras om mankan göra revisions­berättelsen intressantare genom att betygsätta företag iexempelvis intern kontroll och bolagsstyrning.

Inbreeding has become a problem in some horse breeds. Studies show that it may lead to inbreeding depression which affects e.g. reproduction traits. In the wild there are mechanisms that make horses avoid mating with close relatives. When selection is done by humans this mechanism is removed and intensive breeding for a few traits, for example good racing results, can become a problem.
