Amphiphilic Polymers as Additives in Biomedical Polyurethanes. Surface Properties and Morphology

Popular Abstract in Swedish Människor har i alla tider försökt reparera och ersätta skadade vävnader i kroppen. Förr användes naturliga material som t. ex. bomull, silke, tagel och läder. Under 1900-talet har flera syntetiska (konstgjorda) material utvecklats, framförallt olika typer av polymerer (plaster), för användning som ersättning av skadade kroppsvävnader. Beroende på vilken typ av vävnad sThe aim of this work was to achieve surface modification of two biomedical polyurethanes and one poly(urethane urea) through the addition of small amounts of amphiphilic copolymers in solution. The matrix polymers used were the poly(ether urethane)s Pellethane 2363-80AE (P80) and 2363-75D (P75) and a poly(ether urethane urea) similar to Biomer (PUUR). The amphiphilic additives consisted of segment

Floran i Skåne. Arterna och deras utbredning

Detta är det andra fristående bandet av Lunds Botaniska Förenings praktverk om floran i Skåne och utgör resultatet av Projekt Skånes Flora - den inventering av landskapets kärlväxtflora som startade 1990. I Arterna och deras utbredning presenteras de mer än 3600 växter som någon gång påträffats som vildväxande i Skåne. Under Projekt Skånes Flora har 2800 olika växter blivit funna i landskapet och

Emotions in Academia

An old building belonging to the Royal Netherlands Academy of Arts and Sciences, situated on the bank of Amsterdam's Kaisergracht canal, formed the home of a small research department specializing in the study of dialects and Dutch folk culture up until 1988. Excerpts, records, photos and drawings were collected here in these run-down premises. It was a relatively closed setting, not highly ranked

In-group bias control

Popular Abstract in Swedish Många människor förespråkar en egalitär norm. I detta ingår att man ska bemöta människor på lika villkor och inte låta sig påverkas av irrelevanta faktorer som människors etniska ursprung, sexuella läggning eller norska brytning. Forskning visar dock att vi människor tenderar att tänka i termer av kategorier, och detta gäller även hur vi uppfattar andra människor. Vi ärThis thesis explores in-group bias control. It is well-known that people tend to have extra liking for people they identify themselves with. An extra positive in-group attitude may cause discrimination, even in the absence of any negative attitudes towards the out-group. At the same time are many people motivated to behave and present themselves as unbiased. We study whether people attempt to cont

Om konstkritik. Studier av konstkritik i svensk dagspress 1990-2000

The book is a part of the result of a project, funded by HSFR (The Swedish Council for Research in the Humanities and Social Sciences). In general it comprises the art criticism in the Swedish daily press from 1990-2000. The studies have a common focus on the text of the art criticism, in contrast to older research on art criticism, which uses the text primarily as a source of knowledge about the

Electromagnetic Properties of Heterogeneous Material Structures Produced in 3D-Printers

We demonstrate the design, manufacture, and characterization of an X-band waveguide filter using 3D printer technology. The permittivity of the PLA plastic used in the printer is measured to be 2.3 - 0.01j, with about 4% uniaxial anisotropy. The manufactured filter consists of seven dielectric slabs interspace by air. Measured and simulated results agree very well, which shows the possibility of u

The Right to Property and the European Convention on Human Rights. A Nordic Approach.

Popular Abstract in Swedish Avhandlingen behandlar äganderättens skydd enligt Artikel 1 första tilläggsprotokollet till Europakonventionen om de mänskliga rättigheterna.The Nordic constitutions secure the right to property. A fundamental issue under the constitutional provisions guaranteeing the right to property has traditionally been how to distinguish between interference with property rights which come under their scope and those which do not and hence in principle do not enjoy any constitutional protection. This approach has its counterpart in American const

Random errors in antenna technology

This paper deals with far field effects of random errors in antenna applications, for instance due to manufacturing tolerances. The canonical problem is to study expressions that represent the far field power pattern from a collection of sources with far field amplitude. In this paper, the author shows that it is possible to derive quite general results from an arbitrary probability distribution,
