Nano graphite flakes as lubricant additive
The fundamental method of reducing friction and wear in metal to metal contact manufacturing processes like forging, extrusion, sheet metal forming etc. is based upon surface separation. The separation is usually obtained by adding different types of lubricants to the process. In this work, graphite nano platelets (GNp) powder has been used as a lubrication additive to explore and evaluate the inf
Structural and evolutionary studies of a lipocalin: the alpha1-microglobulin protein and its gene
Popular Abstract in Swedish INTRODUKTION Aminosyror är en grupp små molekyler som finns i våra celler. Totalt finns det tjugo olika aminosyror, vilka kan binda till varandra i långa kedjor varvid de bildar proteiner (äggviteämnen). Proteiner ansvarar för en lång rad funktioner i organismen och varje cell i en organism måste därför kunna syntetisera ett par tusen olika proteiner för att kroppen ska1-microglobulin is a small glycoprotein present in plasma and in tissues surrounding the gastrointestinal and respiratory tracts. a1-microglobulin is a member of the lipocalin protein family and exhibits several of the typical traits of a lipocalin; it binds an unknown ligand which causes the brown color of the protein, it forms complexes with various different proteins and there have been indica
Modeling of intra- and intermolecular potentials
Popular Abstract in Swedish Teoretiska studier av modellering av växelverkan mellan molekyler har utförts med hjälp av NEMO modellen. Modellen är baserad på en uppdelning av växelverkansenergin på Hartree-Fock nivå, i första och andra ordningens störningstermer. Energin är given som en summa av electrostatik-, induktion-, repulsion-, och dispersions-termer. Både intra- och intermolekylära växelverModeling of interactions between molecules is investigated by theoretical means within the NEMO model. The model is based on a partitioning of the interaction energy at the Hartree-Fock level into first- and second-order perturbation theory. The interaction energy is given as a sum of electrostatic, induction, repulsion, and dispersion energies. Both intra- and intermolecular interactions are incl

Food selection and fitness optimisation in insects
Popular Abstract in Swedish Populærvidenskablig sammenfatning på dansk Både løbebiller og springhaler er nyttedyr i det danske landbrugsland. Løbebiller er oftest betragtet som rovdyr, der spiser skadelige insekter i marken og er derved medvirkende i skadedyrsbekæmpelsen. Springhaler er minder insekter, som oftest lever i de øverste jordlag og som hovedsagelig spiser svampehyfer. Svampene nedbrydTo optimise fitness is a continuous process which assists species survival in changing environments. Choosing an optimal diet is an essential part of the optimisation process and a key element of optimal foraging theory. The relationship between food choice and fitness optimisation has been tested on three ground beetles and several collembolan species by using food items naturally occurring in th

Cost Analysis for Crushing and Screening: Development of a Methodology for Determination of Production Cost for Product Fractions
The comminution processes are complex and there has thus far been no, previously published, efficient way to calculate the cost per product and metric ton. The proposed model has been adapted to fit the currently investigated process of crushing and screening (C&S). Deriving from the original model, the proposed new model is presenting the result in cost per metric ton of raw material. It has

Candelaria fibrosoides – a new species from Peru.
The new species Candelaria fibrosoides is described. It is known from one locality in Ayacucho in Peru where it was found growing at high altitudes on shrubs and cacti in open pasture land. The new species is superficially similar to C. fibrosa but differs in having 8-spored asci and a thallus with an ecorticate lower surface.

Growth Intentions and Communicative Practices - Strategic Entrepreneurship in Business Development
Popular Abstract in Swedish Tillväxtintentioner och kommunikativ praktik Strategiskt entreprenörskap vid företagsutveckling Denna avhandling fokuserar på entreprenörers “will and skill”, d.v.s. viljan och den kunskap och färdighet som entreprenören har vid start och utveckling av ett företag. Med vilja avses entreprenörens tillväxtintention och med kunskap och färdighet avses kommunikationen mellThis thesis focuses on the “will and skill” of individuals who take part in activities of running a business. The aspect of “will” is studied in terms of growth intentions and the aspect of “skill” is studied in terms of communicative practices. The overall purpose is to explore how entrepreneurs think and talk about growth and how they act in their communicative practices to express their growth

Optical Studies of InAs Quantum Dots in III-V Semiconductors
I this thesis, optical studies of InAs quantum dots (QDs) in GaAs and InP are presented. The electronic structure of these zero dimensional structures, grown in the Stranski-Krastanow growth mode, was studied by photoluminescence spectroscopy (PL), junction space-charge techniques (JSCT) and photoconductivity (PC) measurements. For the InAs/GaAs system we present single-dot photoluminescence spec

Tibiotalocalcaneal fusion using retrograde intramedullary nails as a salvage procedure for failed total ankle prostheses. Sixteen cases primarily operated on due to rheumaoid arthritis
Between 1996 and 2002, 16 patients with rheumatoid arthritis and failed total ankle prosthesis underwent tibiotalocalcaneal fusion using retrograde intramedullary nails. The functional outcome was evaluated using the AOFAS scoring system and the patients were also asked about their satisfaction. Radiographs were obtained for all 16 cases minimum 1 year after surgery. Thirteen of the 16 ankles wer
