On the Possibilities of Detecting Surface Charges with Second Harmonic Generation and Optical Diagnostics of Polymeric Insulators

Optical second-harmonic generation can be a sensitive probe of atoms and molecules at a surface or interface. For this reason, the method was chosen to study surface charges. Our measurements have been limited by large fluctuations in the frequency-doubled light and the mean value of the signals did not give any consistent changes due to changes in the surface charge. A solid metal constituted the

Matter matters : material communication and the role of book history in the curriculum of publishing studies

Books and other printed matter are media of communication, used to carry and distribute – mediate – "content". A medium, however, is always material, and as such it produces meaning in its own right. So even though content and medium might be separate and distinct entities, they are intimately connected, and in order to be communicated a piece of "content" is always given one or another material f

Uppskattning, kritik och förväntan - i ungdomars berättelser om ett samarbetsprojekt i ungdomsvården

Syftet med denna studie är att analysera hur ungdomar som varit placerade på särskilda ungdomshem upplever, definierar och tolkar ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur de tolkade de i projektet anställda samordnarna. Den personliga aspekten i relationen mellan ungdomar och samordnare framställs som viktig och det verkThe purpose of this study is to analyse the way young people who were institutionalised in so called special youth-homes experienced, defined and iterpreted on the one hand the project “Motverka Våld och Gäng” (meaning: “Counteract Violence and Gangs”), and on the other hand the Coordinators employed in this project. There is a big variation in the perception of the coordinators. One common deno

Studies on Oral Immune Reactions in the Genetically Mercury-Sensitive BN Rat and in the Hyperplastic BN-(BNxLEW) Graft-versus-Host Disease

Mercury (Hg) is known to induce adverse immune reactions in sensitive individuals. e.g. selected inbred animal strains. Such reactions involve oral tissues and may reflect immune phenomena, that may also occur in some human oral diseases. Administration of low doses of HgCl2 to the genetically Hg-sensitive BN rats results in the development of a syndrome with autoimmune features [BN(Hg)]. inolvin
