COMPARATIVE STUDY OF HYDROLYSIS PERFORMED WITH MODERN MICROWAVE TECHNIQUE AND THE TRADITIONAL METHOD
Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.
TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis
Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .
Värdering och jämförelse av kvalitetsfaktorer för lokal kollektivtrafik i Helsingfors och Göteborg
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Ekologiska VA-system i Hestra Parkstad, Borås.
This thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures. The main objective of this part is to clarify the contrasts between Iranian and Swedish cultural, social, linguistic and family structures, and also the characteristics of the crisis that most immigrants go through on their arrival in the new country. The qualitative method also involves structured telephone interviews with eight highly educated Iranians.This method was supplemented by a quantitative study through questionnaires of the attitudes· of lranian immigrants to libraries and reading. Iranians in Sweden turned out to be frequent Iibrary users.

Skriv kort och få fler att tala - Ett försök med kortskrivande kopplat till samtal
This papper i about trying en educational method called writing connected to dialog. This is tried on adult students studying to work in Swedish day care. The purpose was to see if this method could make a difference in classroom democracy..

Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Utvärdering av mätmetoder för att fastställa lackmängden vid offsettryckning on-line
This project has been made in cooperation with Stora Enso Research Centre Falun (Research). Thebackground of the project is that Research has customers who demand a method to measure the quantityof varnish online in offset printing. The aim with the project is to investigate if any test method correlateswith the quantity of varnish and to improve the understanding of the variables in the varnishingunit. The goal with the project is to develop a functional method. Two printing trials have beenperformed.
Prismodeller för Facilities Management-tjänster
A study has been conducted on how organizations in Sweden administer costs of facilities management services internally. There are three main theoretical methods for administering costs. In the first method, costs are maintained on a central level; in the second method, costs are allocated and in the third method, internal transfer pricing is used. The aim of the study is to identify which methods are applied in practice, to evaluate whether the methods fulfill their intended purposes and to study the relationship between the methods used and the cost level of facilites management services. In practice, a large diversity of methods are used for facilities management costs.

Affärsmetoder, ett undantag ifrån patenterbarhet? -En komparativ studie av USA, Europa och Sverige
There is no commonly accepted definition of a business method. It ought to consist of a method or a process of doing business. Business methods constitutes a broad category of patents, it is hard to tell exactly what can be interpreted in to the term. Most of the world's legal systems have made an exception from patentability for business methods. In the USA the exception was abolished in a case 1998.
Modellbaserad systemutveckling i komplexa verksamheter. En fallstudie av Coremetoden
In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.
