One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.

Antioxidanter är kemiska ämnen som är kapabla till att förhindra oxidation av andra molekyler. Dessa ämnen återfinns i djur- och växtriket och tycks ha en skyddande effekt på cellvävnad genom att motverka skadliga oxidativa reaktioner. Antioxidanter används bland annat industriellt som tillsater i livsmedel och andra produkter i syfte att förhindra oxidativ degradering och bibehålla näringsvärdet i livsmedel. I vindruvor återfinns höga koncentrationer av naturliga antioxidanter, främst i form av fenoliska ämnen. På grund av att vinindustrin bidrar till stora mänger avfall, främst i form av druvrester, är det önskevärt att hitta en effektiv metod för att återvinna fenoliska antioxidanter från avfallet.I detta arbete användes lösningsmedel-extraktion för att extrahera fenoliska ämnen från pressrester av röda vindruvor av varianten Tempranillo.

The topic of this essay is the expected effects that can come during and after a mega event and how the local impact may affect the local community and the citizen. This essay concerns a forthcoming mega event, the Olympic Games that will be held in London 2012. The area that the Olympics will be held in is Stratford that is located about twenty minutes from the central of London by the underground. The Olympic Games is one of the largest mega events with its millions of visitors. The purpose of this essay is to study what is expected after the mega event has taken place in London.

This essay is about Abrahams children and its teaching method  the IE- method. The purpose of this essay is to see what four teachers who use the method in their teaching think about it. To get an idea of how these teachers are working with the IE- method, I interviewed them. What are the pros and cons, is it a good way to teach religion? In addition, I look at how the IE- method follows the Lpo94 values and goals.

Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.

My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.

Due to the interest of starting a preschool with a scout profile in my circle of acquaintances I chose to write my report about how the scout method would work in a preschool. I did this by comparing the origin of scouting and preschool. I based my report on the following questions:Are there any similarities or differences with curriculum, education act and the scout method that can make it easier/harder to work with the scout method in the preschool?There are many theorists that have had influence on the preschool. Give some examples of their theories that could affect the scout preschool?What is the difference between a teacher and a scout leader?What would a preschool look like if you included the scout method in the daily activity?With the help of my literature studies I compared the scout method against the laws and rules to make sure that the scout method doesn?t contradict them.

The purpose of this study was to find out what the educators view on the working method Matte på burk in preschool looked like. I also wanted to find out what the educators thought about the working method. My questions are:How does the educators in preschool experience the method Matte på burk?What do the educators in preschool believe that Matte på burk can give the children?The study was carried out through a qualitative interview study with six educators. During the interviews with the educators it became apparent that the method not only focused on mathematical exercises.

The case method is a relatively new pedagogical method in Sweden that is based on students exercising their skills in the analysis of complex situations and problems that are based in reality and that help students to see a broader perspective and context.The purpose of this study has been to investigate, through interviews with students and teachers, the advantages and disadvantages of the case method in teaching geography.The results of the study show that both teachers and students share almost the same opinion. The conclusion is that the case method is a didactic method that is well suited for teaching geography, as it is based on reality and develops the students? ability to analyze, argue and find solutions in several areas within the subject of geography. If a student is strong in these skill areas they can really benefit from the application of the case method in the teaching of geography, but for students who are weaker in these skills, the case method can be a disadvantage.

The purpose of this thesis was to develop and optimize a method of analysis for combustion of organic chemical products, followed by an ion chromatographic quantitative analysis. This was to be achieved with the decomposition equipment IKA AOD 1. The aim was to receive a precise and repeatable method that would be able to be applied to the process of qualification and technical marking of chemical products at the company, OKG AB in Oskarshamn. A complete instruction for the decomposition equipment and the method of analysis was written. A number of parameters were chosen from the general method of the combustion equipment, which then was tested parallel with a simultaneous development of an appropriate ion chromatographic method.

AbstractMy purpose with this study was to learn more about different ways to teach children how to read and to investigate how teachers can use more fiction when they teach.During the years that I have been working in school, I have only met teachers who use a method that is built on sounds. The children learns to read from books where the words is not put in their right purpose; for example; we can se a sun, a dear looks down in a lake.After my teacher-education in literature I became more and more interested in if it could be possible to use more fiction when you teach children how to read. I also wondered if it was possible to find readers where the sentences are put in a meaningful story.I heard of a method called Whole Language, or the kiwi-method and I decided to find out more about that method. I decided to make a comparison between the ?sound-method? and the Whole Language-method.I have been using qualitative interviews with both children and teachers with experience from these different ways of teaching.

The construction industries are relatively conservative type of business that takes a longtime to adjust for new methods and embrace new ideas. It dose not matter if the newmethod seems to be an improved method as long as it is new and untried. Constructioncompanies are reluctant to change form a longtime working method to a relativelyunknown method.The purpose with our report is to perform an evaluation of BeWi construction method.Our goal are to present the generally opinion about BeWi from the contractors that hasbeen in contact/worked with the method. We also want to know from the contractor?spoint of view if BeWi and the method measure up to the standards that are presented byBeWi and if they believe that improvements need to be done.Our progress up to the final report has consisted of three parts[1]Field studies[2]Interviews[3]Literary studiesWe started out with field studies where we took notes and observed all the includedworking phases on the construction site when using the BeWi method.

The purpose of this study is to investigate the teachers? described experiences of advantages as well as disadvantages of Arne Trageton?s write to read-method (?ASL?) in contrast to the code-oriented traditional way of teaching. The aim of this study is furthermore to depict the teachers? opinions on whether they experience that the ASL-method is unfavourable for students in general. This study will also investigate the teachers? standpoint regarding choice of reading and writing method.

The purpose of this study is to examine the importance of a working laboratory in mathematics education, how it influences students? learning and the confidence the teacher has in the laboratory component. Focus has been placed upon the advantages and disadvantages that could follow in the working method.The method used in this essay is qualitative in order to answer all the questions that arise along the way, and in order to use this method in interviews. The interviews that has taken place has been with five class teachers that are currently teaching at a elementary school between the years of 1-5. The purpose of this study has been answered by using its literature and the qualitative method with the class teachers.The results of the research show that teachers express gratitude towards the method in use for mathematics studies.
