Biosensors for Food Analysis: Development and Applications

Reliable analytical methods are increasingly needed in the food and beverage industry for the determination of specific components (e.g. sugars, proteins, vitamins, fats) and for detecting and quantifying chemical contaminants such as pesticides, heavy metals, antibiotics, and pathogenic microorganisms. The need arises from numerous regulatory actions and increased consumer concern about food comp

ON ARTHRODESIS AND REPLACEMENT OF THE HUMAN ANKLE

Of 30 primary ankle fusions in patients with osteoarthrosis, 25 ankles underwent clinical evaluation by two independent observers. In 29 cases, two independent radiologists, unanimously found 26 ankles to be radiographically fused, and three not fused. The consistency between the two orthopaedic surgeons evaluations was somewhat lower. A complete consistency between the evaluations of all four obs

Core-excited smoothly terminating band in Xe-114

High-spin states have been studied in neutron-deficient Xe-114(54), populated through the Ni-58(Ni-58,2p) fusion-evaporation reaction at 230 MeV. The Gammasphere gamma-ray spectrometer has been used in conjunction with the Microball charged-particle detector in order to select evaporation residues of interest. The yrast band has been greatly extended to a tentative spin of 52 (h) over bar and show

Förändringsförsök och identitetsdramatisering. En studie bland nördar och slipsbärare

There is a vast amount of normative literature on change, which primarily focuses on how to manage change in an efficient and successful manner. What actually happens when management attempt to put their plans into practice is more seldomly investigated. Moreover, the prevailing literature on change primarily takes a management perspective. Other organizational members are usually treated as suppo

Self-assembly in Melts of Block copolymer-based Systems Featuring Supramolecular Interactions

Popular Abstract in English From everyday experience we know that water and oil do not mix. In the scientific language we say they phase separate from each other. This happens because a water molecule and an oil molecule are inherently incompatible, the former exhibiting a ‘polar’ character and the latter a ‘non-polar’ one. Water and oil molecules are small, meaning that they are made up of only The subject of this thesis is experimental investigation of self-assembly in solvent-free (ionic) macromolecular systems that contain block copolymer chains as the basic constituent component in combination with low molecular weight amphiphiles. In particular, especial attention is paid to study thoroughly a new class of block copolymer-based ionic supramolecules, named as Linear-b-AmphComb, that

Våldets kön : kulturella föreställningar, funktioner och konsekvenser

Vi möter våld i någon form dagligen, om inte som ”offer” eller ”förövare”, så när vi läser tidningen, tittar på tv eller går på bio. Hela världen kan förefalla organiserad med utgångspunkt i våld. Med våld upprätthålls stater, grupphierarkier och individuella maktpositioner. Merparten av våldsutövarna är män liksom hälften av offren. Den andra hälften av offren är kvinnor och barn. Det här mönstre

Influence of pressure drop in PEM fuel cell stack on the heat and mass balances in 100 KW systems

Proton Exchange Membrane (PEM) fuel cell systems have been studied as the alternatives of the internal combustion engine systems. However, these systems are not appearing in daily life yet, due to the high cost, shortage of infrastructure, technical issues, etc. Concerning technical issues, water/thermal management is a critical one to keep high proton conductivity in the electrolyte membrane for

Bioreduction of Carbonyl Compounds to Chiral Alcohols by Whole Yeast Cells: Process Optimisation, Strain Design and Non-Conventional Yeast Screening.

Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. The aim of this thesis was to develop ef

A non-feedback multiphase clock generator

This paper introduces the design of a new multiphase clock generator with no feedback loop. A single-stage direct interpolation architecture is proposed. A 1/4 frequency divider and a short-circuit current suppression interpolator are developed to achieve the precise interpolation. The circuit has been fabricated in a standard 0.35 μm, 3.3 V CMOS process. The multiphase clock generator can operate

Metaphor, similarity and semantics fields

A variant of the compatrison theory of metaphor is put forward. The main points are (a) a theory of metaphor belongs to semantics, not pragmatics, (b) a metaphorical statement is a similarity statement, usually comparing descriptions of objects, (c) a metaphor is a constellation of words connected by a certain kind of relation - the metaphorical link, (d) metaphors are not necessarily asymmetric,

Environmental value orientation as an explanation of differing motives for conservation of the local biodiversity.

Biological diversity encompasses the genetic diversity within each species, the range of species in a given ecosystem e.g. species diversity and the diversity of ecosystems across an entire region (Primack, 2000). At present 1 per cent of the world’s described species are threatened with extinction. The most pervasive and overriding threat is habitat loss and degradation due to human activity such
