Canonical bases, also called SAGBI bases, for subalgebras of the non-commutative polynomial ring are investigated. The process of subalgebra reduction is defined. Methods, including generalizations of the standard Gröbner bases techniques, are developed for the test whether bases are canonical, and for the completion procedure of constructing canonical bases. The special case of homogeneous subalg

Popular Abstract in Swedish Paternalism i allmänläkarens vardag - om läkarens makt och patientens rätt till självbestämmande. I mitt vardagliga arbete som allmänläkare möter jag patienter med olika symtom och sjukdomar. Hur bör allmänläkaren förhålla sig till en patient som ställer krav på en åtgärd – en speciell undersökning, ett recept på en viss medicin eller ett intyg – som läkaren inte finneThe overall aim of this thesis was to identify and analyse situations raising the question of possible paternalism in everyday general practice in Sweden. Both questionnaires to a random sample of respondents and interviews have been used. The ethical awareness among GPs in Sweden and the variety of ethical issues, suggest that medical ethics is a subject of high relevance in general practice. Th

Popular Abstract in Swedish Utvecklandet av helt nya baspolymerer för tillverkning av massprodukter förväntas i framtiden vara begränsad p.g.a. för höga investeringskostnader. En av de mest tydliga trenderna inom polymerindustrin idag är istället den ökande betydelsen av polymerblandningar. Kombinationer av två eller flera polymerer som bildar fasseparerade strukturer i blandning ger ofta materialOne of the main trends in the polymer industry today is the increasing importance of polymer blends. Combining two or more immiscible polymers in a polymer blend often leads to multi-phase materials with desirable properties. The typical poor morphological stability and low interfacial adhesion in these blends can be eliminated by adding compatibilizing graft copolymers. Well-defined graft copoly

International trade legislation and TRIPS in particulate contain elements of a competition law system. Flexibilities in the system leave substantial discretion to developing countries, which can apply these rules to counterbalance demands imposed on them by the IPR obligations contained in the Agreement. To create a reasonable balance, precise standards regarding competition law interpretation and

Denna bok är ett bibelvetenskapligt bidrag till förståelsen av den mänskliga existensens villkor tiderna igenom. Boken ifrågasätter många av de traditionella tolkningarna och ger ofta alternativa perspektiv på lidandets gåta, inför vilken alla andra frågor kan förefalla oväsentliga. Plötsligt står vi inför smärtan i livet: lidande, sjukdom och död. Varför drabbar olyckan mig och hur är Gud inbland

The purpose of this paper is to investigate the relevancy/feasibility of the postponement strategy in food supply chains. The paper also aims at discussing the windows of opportunities for the growth of use of postponement by identifying the factors/drivers/enablers in the adoption of this strategy. It is out of the scope of this paper to survey a specific market/country, or answer how much or how

Background: A number of trends during the last decade, like globalisation, outsourcing, single sourcing, leanness and agility, have made the supply chain more vulnerable and “supply chain risk management” has become a research area of its own. Objective: To characterize the existing scientific knowledge and scientific knowledge creation within supply chain risk management as it is presented in the
