Determination of Fat-Soluble Vitamins in Foods Based on Supercritical Fluid Extraction
Popular Abstract in Swedish De fettlösliga vitaminerna upptäcktes i början av 1900 talet, och indelas i klasserna A, D, E och K. Brist på vitaminer i kroppen kan leda till svåra sjukdomar som nattblindhet, benskörhet och cancer. Även en överdos kan vara mycket allvarlig, och därför finns det bestämmelser om vilka livsmedel som ska vitaminberikas samt med hur mycket av varje vitamin. Dessutom utförSample clean-up methodologies based on supercritical fluid extraction (SFE) have been developed for determination of fat-soluble vitamins in foods. This thesis focuses on method development, stressing important issues concerning sample pre-treatment, extraction conditions and collection parameters. It was demonstrated that by using SFE followed by saponification and determination using RP-HPLC wit
Om Meret Oppenheims visuella världar
This book chapter discusses Meret Oppenheim's art as a central contribution to European modernism, and provides a critique of the male dominated art history writing.
Towards a minimal argument structure
In this paper I give a short presentation of a syntactic approach to argument structure, taking a particular implementation of the minimalist framework (Chomsky (1995, 2001 and later)) as my point of departure. The proposed account allows for only 16 different argument structures, thereby reducing the syntactic variation at this level of syntax considerably. The theory also offers an explanation w

Computer Exercises in Mechanics for Industrial Engineers
THESE EXERCISES SERVE THE PURPOSE OF TRAINING THE UNDERSTANDING OF SEVERAL BASIC CONCEPTS IN ELEMENTARY UNIVERSITY-LEVEL MECHANICS. WHEREAS MECHANICS IS OFTEN TAUGHT AS A COURSE WHERE “PEN AND PAPER” ARE THE ONLY TOOLS, THESE EXERCISES ATTEMPT TO PROVIDE KNOWLEDGE ON HOW THE BASIC THEORY WORKS, ON PRACTICAL PROBLEMS, BY USING A MODERN SIMULATION COMPUTER SOFTWARE. BY SIMULATIONS THE GENERAL PERFOR
Exploring the Possibilities of 14C Bomb-Pulse Dating of Human Tissue Samples
Popular Abstract in Swedish Levande organismer, inklusive människor, har en 14C/12C-kvot som återspeglar miljön. När materialet dör slutar kroppen att fylla på 14C och kroppens 14C börjar sönderfalla till 14N. Detta gav upphov till den klassiska 14C-dateringsmetoden, vilken utvecklades av professor W.F. Libby, 1949 och gav honom Nobelpriset i kemi 1960. 14C-datering används huvudsakligen inom arkeThe testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. living after 1955) material , based on the 14C/ 12C ratio in it. The objective of this work was to evaluate the factors that c

Når läkarutbildningen de resultat som yrkeslivet förväntar? – alumnundersökningar 3 och 7 år efter läkarexamen.
Undersökningens uppläggning Enkäter skickades i maj 2005 till dem som tagit läkarexamen i Lund 2001 och 2002. Frågorna berör både medicinsk och allmän akademisk kompetens. En uppföljningsenkät gick samtidigt till dem som tagit examen 1997 och 1998 och ingått i en tidigare alumnundersökning. Avsikten med uppföljningen är att ge en bild av hur arbetsuppgifterna förändras i den tidiga delen av läkark

Self-calibration from Image Derivatives for Active Vision Systems
In this paper we show how to calibrate a camera, mounted on a robot, with respect to the intrinsic camera parameters when the so-called hand-eye transformation between the robot hand and the camera is unknown. The calibration is based directly on the spatial and temporal derivatives in an image sequence and do not need any matching and tracking of features or a reference object. The calibration is
2nd and 3rd generation electrodes for biosensors and biofuel cells
Popular Abstract in English The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and
Multi-Element PAA Calibration with REV Method
Phased array antenna (PAA) calibration is the process of determining the PAA channel characteristics; these characteristics are used in beam forming algorithms. In "contactless" PAA calibration methods, measurements are made by a stationary probe antenna placed away from the tested antenna, and the channel characteristics are determined from the measured data. Two of these methods are the MTE and

Birger Sjöbergs bilder och Tegnérs
The metaphors in the works of Birger Sjöberg is compared to those of Esaias Tegnér. The comparison is made in the theoretical frame of Riffaterre´s concept of hypogram (clichés, descriptive system) and the tradition of domesticating metaphors. Sjöberg is clearly developing Tegnér's metaphorical technique, thus shaping new ways of expressing the depths of mans psyche and his fate, understood within
Three-terminal ballistic junctions: New building blocks for functional devices in nanoelectronics
Present digital logic gates are primarily built from field effect transistors (FETs) such as complementary metal oxide semiconductors with the gate length in the deep sub-μm regime. As device feature sizes approach the nanometer regime, fundamental physical constraints and increasingly prohibitive economic costs will make further miniaturization in electronic circuits difficult, and this has motiv
