The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. We found that titration calorimetry could give quite detailed information about polymer - surfactant interactions. Values for the critical aggregation concentra

We describe a system for automatic annotation of English text in the FrameNet standard. In addition to the conventional annotation of frame elements and their semantic roles, we annotate additional semantic information such as support verbs and prepositions, aspectual markers, copular verbs, null arguments, and slot fillers. As far as we are aware, this is the first system that finds this informat

Popular Abstract in Swedish En betydande del av kemin i naturen och inom industrin äger rum i en omgivning av andra molekyler. Reaktioner, övergångar, interaktioner och andra kemiska processer påverkas nästan alltid utav omgivningen. Dessa modifikationer eller omgivningseffekter beror i grund och botten på växelverkan mellan molekylerna, den så kallade intermolekylära växelverkan. Det speciella faA considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. These modifications or environment effects depend ultimately on the interactions between the molecules, the so called intermolecular interactions. The special case of effects induce

The innocuous place of Hungary’s Jews in the historical culture of the country from 1945 to 2004 is an indication that the Holocaust has not set its stamp on this culture. It is noteworthy that in the last decade of the Kádár regime, there was a strong interest in Hungary in the fate of the Hungarians in the territories that had been lost at Trianon. This interest was an important factor in Hungar

Popular Abstract in Swedish Marknaden för bestrukna tryckpapper har vuxit snabbare än för andra papperskvaliteter och förväntas göra så även i framtiden. Drivkraften bakom denna utveckling är kraven på bra färgåtergivning, framför allt inom reklamsektorn. Bestrukna papper blir en allt viktigare produkt för den svenska pappersindustrin men det är också ett område där konkurrensen och produktkraven This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. The seed latexes used were polystyrene, whose properties had been changed by copolymerization with methacrylic acid (MAA) or divinyl benzene. The second-stage polymers were copol

Popular Abstract in Swedish Växter kan bli attackerade av många olika sorters bakterier, svampar, virus, insekter och betande djur. Därför har växter utvecklat flera olika försvarssystem mot patogener. Bland annat kan de ha skyddande ytskikt, antimikrobiella molekyler och proteiner. Men växter kan också leva i symbios med bakterier och svampar. Baljväxter bildar rotknölar där kvävefixerade bakteriPlants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. In this work, different factors involved in plant-microbe interactions have been

This thesis investigates the connection between open access – the free online availability and distribution of scientific and scholarly publications – and the ‘developing world’ from a post- development perspective. It takes a discourse analytical approach, drawing predominantly on Michel Foucault’s understanding of discourse. It aims to answer the following questions: - Which notions of science,

BACKGROUND: The earliest immune events induced by allergens are poorly understood, yet are likely essential to understanding how allergic inflammation is established. OBJECTIVE: We sought to describe the earliest signaling events activated by allergen and determine their significance to allergic inflammation. METHODS: A fungal-associated allergenic proteinase (FAP) or ovalbumin was administered on
