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. .

Then we want, from different sized companies, analyze and study howthey work with the key properties in creating a good customer relationship and hencecustomer satisfaction.

Resultatet av Formatet- En kvantitativ studie om butiksformats påverkan på en konsuments beteende och attityd

Today's consumer society has led to never-ending choices in terms of brands, products and prices in an endless variety of shops. The retail industry is a very complex industry that includes many different types of sales channels and many different types of products. A consequence of this trend is that brand owners today face difficulties in understanding how their products are being evaluated and difficulties in knowing which final cause that make a consumer willing to by their product is hard to figure out. The industry is very diversified, which means that for a company to really understand their position and their role on the market it requires that the company put a lot of effort and also a lot of money in the process of trying to figure it out. We will with this paper try to explain a small piece of that understanding and we hope to get results, which contribute to the further research in this area.

Telekomspecialisering i Östra Europa - Integrationens betydelse för en produktionsfragmenterad industri

One of the most distinguishing features of contemporary globalisation is production fragmentation, a splitting up of the manufacturing of a good into several different stages. Production fragmentation creates new opportunities through vertical specialization; a country incapable of mastering the entire production process may specialize in the manufacturing of one separate part. The aim of this thesis is to examine to what extent international integration affects a country?s ability to engage in vertical specialization in an industry characterized by production fragmentation. The analysis focuses on the european integration process over the last decade, where countries in eastern Europe with relatively low labour costs have been integrated with more capital abundant western economies.

Hälsoeffekter från trafikbuller vid Bäckegatan

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

Vad ?r en funktion?

The concept of function represents a major part of mathematics and becomes more significant in school during high school. Throughout history, it has been a difficult concept to define and may create challenges for contemporary students. This literature study aims to identify students' difficulties with the concept of function, as well as to account for how the definition of a function has evolved historically. The literature study has been conducted through database searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as through chain searching. The study results in identifying that students' difficulties with the concept of function primarily include the graphical and algebraic forms of representation.

CSR och B2B, olja och vatten? : En undersökning av CSR som konkurrensfördel inom Business-to-Businessmarknaden

The aim of this thesis is to examine how secondary teachers in the subject of history are using the textbook in their teaching. Four questions are being dealt with in this thesis. What importance is being placed on the use of history textbooks by the secondary teachers? What priorities do the secondary teachers have? How do they deal with student interests? And what is the importance of the secondary teachers? work experience? I have interviewed four secondary teachers with different work experience to complete this thesis. A Dictaphone has been used in all the interviews. Research has shown that textbooks now have a central role in teaching and the lack of alternative materials and reduction of teaching hours has made it difficult to replace. The main conclusions of the thesis are that the history textbook has a dual role depending on the teacher you ask, and that the history book is used differently by the teachers.

Läsutveckling utifrån ett sociokulturellt och mångkulturellt perspektiv

The purpose of this investigation is to compare the teaching in reading of three pedagogues in form 2 in three different schools from a second language perspective. Among other things it implies to investigate how the pedagogues think of teaching in reading and the reading field to be compared with if these fields are adjusted to a diverse cultural perspective. This investigation is carried out through observations and interviews. To compare the schools they have been picked out from the number of pupils and the number of second language pupils, that is 15 %, 67 % and 95%. The investigation also includes how the pedagogues weigh the pros and cons within reading and working methods.The further reading is built upon theories and previous research that have an attachment to the view of the sociocultural and the diverse cultural perspectives of teaching.

Statistiska metoder för härledning av indata till säkerhetsanalyser inom kärnkraftsområdet

Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.

Den demokratiska lyxen

Abstract: The fashion industry is perhaps the most unpredictable one where change occurs very rapidly. In order to be attractive and interesting in this competitive industry, a brand must constantly be up to date and differentiated from other brands to attract the consumers. This has given rise to an increasing growth of brands that cooperate for marketing reasons and more specifically, clothing retailers that perform designer collaborations with exclusive designers to create limited collections.Studies describing the effects of those collaborations on the retailers brands are rare and especially from a consumer perspective. Since H&M has been a pioneer in designer collaborations and has done it more times and for more years than any other retailer we have conducted our study on their case. Our intention was to investigate how the designer collaborations have affected the brand equity and image of H&M, if the collaborations have increased the willingness to pay for H&M's other ranges and if they have affected H&M's ability to extend its brand to higher price segments, through an experimental study.

Ställtidsreduktion i montering av kopplingar

VBG Produkter AB is a process-orientated company that develops, manufactures and markets trailer couplings with belonging coupling equipment, protection equipment against skidding and stands for wagon-bridge for heavy vehicles. The company feels that their set-up time in production for couplings is not at an acceptable level. Due to high demands of customer oriented production the intermediate stock level of included products within the assembly of couplings has gradually increased which has resulted in high inventory holding costs. VBG Produkter applies Kanban in their production, therefore it is important to produce exactly the necessary amount and avoid overproduction. The objective of this project is to suggest appropriate solutions so that VBG Produkter is able to reduce their set-up time in assembly of couplings, by identifying internal and external set-up time for the chosen process bushing cell.

Relationship between moose (Alces alces) home range size and crossing wildlife fences

Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.

Spelar geografi roll? : En studie av Bolognaprocessen ur ett policy transferperspektiv

AbstractDoes Geography Matter? A Study of the Bologna Process from a Policy Transfer Perspective.Essay in Political Science (D-level) at Karlstad?s University by Beatrice Högå, Spring 2007Tutor: Susan MartonThe purpose of this essay is to generally see how theories of policy transfer can help us to better understand the process through which the Bologna Process is being spread throughout Europe, and to specially see if geographic placement, i.e. in the heart of Europe, plays a role in how well and how fast the Bologna Process is implemented.To be able to answer the purpose, I have used Evans and Davies theoretical model on policy transfer network to describe the Bologna Process. Furthermore, Sweden and France are the countries being examined when they differ on the independent variable. From there, I have applied an analytical tool, namely process tracing, to examine whether there are differences in the two countries? work with the implementation of the Bologna Process.I have designed six specific research questions:Have France performed more extensive work than Sweden when it comes to implement the two-cycle system?Have France performed this work earlier?Have France performed more extensive work than Sweden when it comes to recognize awards and periods of study?Have France performed this work earlier?Have France performed more extensive work than Sweden when it comes to quality assurance?Have France performed this work earlier?After applying the analytical tool to be able to answers these research questions, the answer to the general question Does geographic placement, i.e.
