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.

Kapitalbindning och lönsamhet på 1980- och 2000-talet

This article is about Abrahams Children foundation and its teaching Method called IE- Method. It?s about how a teacher can use the IE- Method in the religion lesson. There were some questions in this article that had to be answered and the questions are:- How is the form of the religion classes when a teacher uses the IE- Method?- What happens in the class when you study the interaction and the communication?- Does the student?s participation increase when they work with the IE- Method?- What are the advantage and the disadvantage with the IE- Method?- Can the teacher use the IE- Method in other classes?To get to the ?correct? answer I used many Methods like, observation in the class, qualitative interview with the teacher (Lisa Andersson) and with four students (Kim, Erik, Amanda, Patrik) and I also used questionnaire.

Läsundervisning- att följa en metod eller ej? : En jämförande studie om lärares val av metod i arbetet med den tidiga läsinlärningen

This is a study of how four teachers work with pupils? early literacy learning. Interviews were conducted with two teachers who chose to use a specific Method, Writing to Read (WTR), for teaching pupils to read, and with two teachers who had not chosen a specific Method. The aim of the study was to compare how the teachers worked, their motives for their choice of Method, and the ideas the teachers have about early literacy learning. To see whether the teachers? choice of Method was related to the individualization of the teaching and their views of pupils? learning in interaction, Vygotsky?s theories about children?s learning have been used.

The objective of this study was to study the agreement between two Methods of indirect bloodpressure measurement in dogs and cats and to establish the within-Method variation for the Methods. The utility and practicality in the clinical setting were also evaluated for the both Methods. The techniques evaluated were the oscillometric Method and the Doppler ultrasonographic Method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

Styrkor och svagheter med problembaserat lärande-en metastudie

AbstractProblem-based learning (PBL) was from the beginning developed in medical school, but is today used in education in other programmes as well. Investigations about PBL have been conducted in different disciplines and there is also metastudies. In this paper, a metastudy of 8 bachelor degree papers have been conducted. The questions answered were: which Methods were used to investigate PBL in primary, lower secondary and upper secondary school,which advantages were found in working according to the PBL Method, which disadvantages were found in working according to the PBL Method and did teachers and students views about advantages and disadvantages about PBL as a Method differ and if they did, how? The results showed that mostly qualitative Methods were used to investigate the PBL as a Method, mostly abilities of social qualities and independence were trained in working according to PBL, a disadvantage was that working according to the PBL Method was considered more resourse consuming than traditional teaching Methods and teachers and students views about PBL did not differ considerably.

pm3-revision : En välgrundad metodutveckling av metod för revision av förvaltningsstyrning

In the field of maintenance management there are but a few models an organization can use. The one model that has risen to the status of being the de facto standard in Sweden is pm3(på maintenance management model). The aim of this study is to lay the groundwork for a new Method of evaluate the use of pm3within organizations. Today there is no uniform way of performing such an evaluation, which is necessary in order to diagnose the performance of the systems maintenance organizations.In the process of creating our own Method for performing this kind of pm3audit, we further developed the ideas from a study by Lagsten & Nordström (2013) that was performed at the county Region Skåne. The authors of that study had developed ideas about using Method rationale as a basis of creating a Method for pm3auditing.

Diskontinuerliga Galerkinmetoder för initialvärdesproblem och prissättning av optioner

Efficient numerical Methods for option pricing is an active field of research. This project has the goal to examine possible ways to improve an established Method of numerical pricing. The Method is based on an adaptive finite difference Method in price and uses the backwards differentiation formula of order 2, BDF2, in time. The project will focus on improvements to the time integration through implementation of discontinuous Galerkin Methods, dG. Empirical convergence and accuracy results are obtained for equidistant dG-Methods up to order 3 and performance is compared to BDF2.

Jämförelse av metoder för peroxidbestämningar i bränslen : A comparison of methods for determination of peroxide content in fuel

New energy resources that can replace petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine Method, which involves GC-MS analysis has been compared to the standard iodometric Method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric Method worked and also in order to make a calibration curve in GC-MS.

Under parasollen : En komparativ studie utifrån whole language-teorin och LTG-metoden

AbstractThe purpose of this study is to analyse the reading- and writing-approaches: the LTG-Method and the whole language-theory. The attention is to perform a comparative literate-study to distinguish their similarities and differences, and examine which one of the approaches that is most clearly anchored in the syllabus of the subject Swedish. The starting-point of the study is the questions: Which similarities respectively differences have the LTG-Method and the whole language-theory? Which one of these theories is most clearly anchored in the syllabus of the subject Swedish? The study has shown that both the whole language-theory and the LTG-Method can anchor in the syllabus for Swedish. However the whole language-theory has stronger hold in the syllabus, as the whole language emphasises the meaning of literature for reading- and writing-learning, and considers the pupils reflection during their learning-process and conquered knowledge-goal.

Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion

Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC Method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a Method to quantify the pH adjusting components, X and Y were also made. These two Methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a Method for quantification, and HPLC with ELS detection was chosen after a long series of trials.
