Interferences during analysis of polyphenols in fruit juices

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.

VILKEN STRANDVEGETATION BIDRAR TILL DET ORGANISKA MATERIALET I KUSTN?RA SEDIMENT? Kols?nkor/k?llor, nedbrytbarhet och eDNA sp?rning

Coastal sediments are important carbon sinks, storing organic matter and thereby helping to reduce the amount of greenhouse gases in the atmosphere. However, they can also act as carbon sources if the deposited organic matter decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the Swedish coast, based on coverage data from the ClimScape project (www.climscape.se). For the most dominant species, I investigated the type of organic matter they may contribute to the sediments and based on those results I qualitatively assessed which sites that may function as carbon sinks or sources.

Döden är livsviktig : fem kuratorers bemötande av obotligt sjuka och deras bild av de sjukas upplevelser

Modulbyggd förskola - Framtiden?

In 1999 the childbearing increased, which in combination with the closure of a number ofpreschools led to the shortage and reduced capacity in available places for youngchildren. The lack of places in preschools has led us to try to find a solution to theproblem and in order to solve the problem we have interviewed personnel of preschoolsin Halmstad. The persons we met were asked to list advantages and disadvantages oftheir preschool and also to come up with innovative solutions and new ideas of how todevelop a satisfactory preschool. This was the basis for us when we drew our drawingsand our main objective was to find a new template for the development of pre-fabricatedpreschools.When drawing a new and modern preschool a number of considerations have to be made,first of all the main objective for the children is play and playtime, a second objective issound reduction and laws about sound reduction. Another consideration is how toconstruct the building and which method to be used, for instance should industrialtechniques be considered and pros and cons be listed.The main disappointment amongst the preschool personnel was that they had noinfluence in the planning stage of the new development of the preschool.

Grupperingar i en nysammansatt klass

The purpose of this paper is to try to get an understanding of the underlying causes and reasons that students starting in seventh grade junior high school seek out a particular group, and the extent to which they do so.The work is based on the questions: How do students perceive the meeting with their prospective bench-companion in a new composite class? What should a teacher consider when it comes to bench placement in a new composite class? Do the students change, and if so to what extent, friends when they start high school? What are the factors that affect/have affected the students' choice of friends? How large a role does the school play for pupils relationships? What thoughts and feelings do the students have regarding new encounters?I have conducted in-depth interviews with six adolescents in grade seven as the basis for the understanding of how students relate to group selection and group affiliation, and I have then compared this material with previous research on the subject. Furthermore I have availed myself of literature in social- and group psychology.The conclusion which has emerged is that the most important component of a group-process is the sense of solidarity and security, and the results show that students largely retain their old relationships rather than adding new, when they start high school. Hence the teacher plays an important role in ensuring that any imbalance in the group is offset and make sure that nobody is excluded, but also to help make room for new groups and be aware of the sensitive and responsive phase of life that the young people are in..

Optimering av slutfasstyrning

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

Management of Private Equity Investments: A Study of Swedish Biotech Investment Managers

The Private Equity industry has over the past years been booming and major external environmental changes have made the industry transform rapidly. Increased competition between Private Equity firms is one of the reasons why the industry has been and is being forced to focus more on addition of value through increased operational management. Consequently, the focus of value addition is by some said to be transferred away from deal making and financial skills, and into active operative management. This case study investigates how the portfolio management, and more specifically the measuring and management of performance, is carried out in a number of leading Swedish Private Equity funds with investments in the biotech sector. The biotech sector is characterized by extensive research and development, and many biotech companies often lack income and other measurable financial parameters in the initial phase.

Påverkan från den förväntade klimatförändringen på tillväxten i norra Sveriges skogar : En litteraturanalys

This is a literature review of how the climate change affects the forest growth innorthern Sweden. The temperature will rise about 5 °C with the largest increase in thewinter season (December - February) and the CO2level in the atmosphere is expected tobe doubled. Precipitation patterns will change and increase with 25-35 % and theprecipitation will be in form of rain rather than snow. Today the forests in northernSweden are entirely dominated by coniferous stands. This may shift with the climatechange and results in a larger number of deciduous trees, preferably birch will becomestronger and grow better and faster.

Testbänk för motorbåtsdrev

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

IFRS 9 Fas III: Säkringsredovisning ? Förenkling eller bara förändring?

Den i dagsläget mycket komplicerade IAS 39 som bland annat berör säkringsredovisninghade en del till den stora finanskrisen enligt vissa. Oavsett bakgrund så har utveckling av enny redovisningsstandard för att ersätta och förenkla säkringsredovisning påskyndats. Ettförsta utkast av förslag till förändring för redovisning av säkringar presenterades i december2010. IASB som leder arbetet har redan kritiserats, så hur tar användarna ? företagen emotförändringsförslagen? Genom att ta del av företagens skriftliga åsikter är studiens syfte attundersöka attityderna till förslagen i exposure draft IFRS 9 Fas III Säkringsredovisning.Detta är en kvalitativ studie där datainsamlingen består av comment letters i vilka företag harskrivit sina kommentarer och uttryckt sina attityder i olika frågor om förändringsförslagenställda i exposure draft specifikt skrivna angående IFRS 9 Fas III Säkringsredovisning.

Bättre arbetsberedningar med hjälp av BIM : Hur de kan utformas för implementering av BIM

During the past years Building Information Modelling (BIM), which is a digital way to work, has begun to spread amongst the parts of the construction process. At the construction phase the larger companies has started using the new way to work. This expansion has not been developed amongst smaller companies leading to the purpose of this report, to investigate in which ways the smaller companies can implement BIM by changing their way to work. The thesis is delimited to work preperations with the objective to define how the work preperations should be structured to enable the implementation of BIM. To achieve the objective of the report, information about the subject has been collected by interviews and literature studies.

Bilen - Om samhällsteori och samhällsförändring

The aim of this paper is to empirically examine the ideological trends and positioning of the Swedish liberal party with the Danish social liberal party. This paper also aims to analyze the reasons behind the trends. By examine the development in these two Nordic liberal sisterparties, this paper contributes to our understanding of why and how party change is initiated. The paper commences with an intuitive notion that the Swedish party has in fact, made a lurch towards the right, during the past ten to fifteen years while the Danish party has retained their social-liberal position in the centre of the Danish political spectrum. The questions then asked are: can this hypothesis be verified empirically? If so, how can this phenomenon of divergence, be explained?The method used in this thesis is process-tracing and the empirical material does to a large extent rely on interviews with central agents as they are specified in the theory of each party.
