The Influence of Polyelectrolytes on the Stability of Colloids

Popular Abstract in Swedish Den här avhandlingen handlar om interaktion mellan två ytor (t.ex. fibrer, lerpartiklar eller proteiner) i en vattenlösning med motjoner, salt och/eller polyelektrolyter. Polyelektrolyter är laddade polymerer. Avhandlingen är fokuserad på elektrostatisk växelverkan och interaktionerna har undersöks med hjälp av Monte Carlo-simuleringar. De kvalitativa resultaten har oftThe interaction between two colloids with grafted polyelectrolytes in aqueous solution is studied within the primitive model by Monte Carlo simulations. For neutral colloids with grafted polyelectrolytes and in absence of salt the interaction is strongly repulsive in absence of salt. The interaction depends on the extension of the polyelectrolytes from the surfaces and the interaction is derived a

Meanings of words : theory and application

This chapter presents a Cognitive Semantics framework for the analysis of words and meaning-making in language, Lexical Meaning as Ontologies and Construals, and the basic socio-sensory-cognitive assumptions on which this framework rests. It demonstrates the repercussions of the basic assumptions of the approach to word meaning, highlighting its usefulness for describing and explaining mean-ing-ma

The Creative Personality in a Gender Perspective

Two empirical investigations of the creative personality, including a gender perspective, are described. In one of them the participants were school children and in the other the group consisted mainly of university students. Creativity is here conceived within a particular theoretical frame which is particularly focussing on individual differences in the perceptual process. Gender was studied fro

New reduced state space BCJR algorithms for the ISI channel

A critical component in detection under intersymbol interference (ISI) and in turbo equalization is the BCJR algorithm. We study two approaches to reducing its computation. First, the state space is reduced by optimizing the receiver's phase-maximizing all pass filter. Then the state space used by the BCJR calculation is reduced by breaking the state into an offset and a main state. These procedur

Search for beyond Standard Model physics with same-sign dileptons

Popular Abstract in Swedish Frågorna som partikelfysiker ställer är samma frågorna som folk har ställt under hela mänsklighetens tid på jorden, nämligen: Var kommer vi från? Vad är det som bygger upp det universum som vi ser? Hur håller allting ihop? Fysiker, historiens stora tänkare och hobbyfilosofen i pubben har alla funderat över de här frågorna (vissa mer än andra). Partikelfysiker försöker hAn introduction into the theory and experimental background of particle physics and the ATLAS detector is given. The transition radiation tracker (TRT) which is vital to the particle tracking and identification is then described giving particular creedence to the calibration. The automation of this calibration is explained. The second half of this thesis and the central part dwells on the analyses

The Context of Paratext: A Bibliometric Study of the Citation Contexts of Gérard Genette’s Texts

Based on two sets of data consisting of research articles from Web of Science, analyses were made on articles citing Genette and articles using the paratext concept. The purpose was to investigate the context in which the paratext concept is used and Genette is cited by analyzing the journals and research fields in which the articles were published, the literature these articles are based on, and

Integrating non-genetic inheritance in evolutionary theory. A primer

Evolutionary biology traditionally equates inheritance with transmission of genes from parents to offspring. However, recent literature calls for considering ‘non-genetic inheritance’ in evolutionary theory. These calls have met with substantial scepticism. What is more, they appear to have caused further confusion both with respect to what inheritance is and what types of inheritance mechanisms a

Carex humilis - a caespitose clonal plant: ramet demography, ring formation, and community interactions

Popular Abstract in Swedish Carex humilis - en ringbildande klonväxt Växter som kan föröka sig asexuellt kallas klonväxter. Det genetiska individet (geneten) består då av flera självständiga plantor (rameter). Exempel på klonväxter är hallon, jordgubbe, kvickrot, potatis, tulpan och vitsippa. Den här avhandlingen handlar om ett centraleuropeiskt klonalt halvgräs, som heter Carex humilis på latin Carex humilis forms rings of densely aggregated ramets in dry grassland vegetation in Central Europe. In the thesis I conclude that ramet demography is important both for analyzing fitness in clonal plants and for understanding how C. humilis rings are formed. I studied the ramet demography of C. humilis from 1993-1998 at the Hexenberg mountain, 300 m.a.s., 60 km east of Vienna, Austria. In total,

Electronic structure of nanometer-sized semiconductor crystals

We report on a theoretical study of the electronic structure of semiconductor nanocrystals, based on a tight-binding method. Both one- and zero-dimensional structures have been studied. Concerning the one-dimensional structures, the effect of the confinement on the band structure of nanowires has been studied. We find that a transition from direct to indirect band gap occurs in the band structure

Grundad teori : Teorigenerering på empirisk grund

Grundad teori är en metod för kvalitativa undersökningar inom samhälls- och beteendevetenskaperna. Den utvecklades på 1960-talet och har blivit allt mer spridd. Det är en induktiv metod, baserad på idén att man växelvis samlar in och analyserar data. På detta sätt kan teorier som är helt grundade i data genereras. Metodens komplexitet, och olika tolkningar av den, har emellertid lett till att det
