  2. 1. Polymer Mediated Surface Forces

    Author : Martin Turesson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte Solutions; Charge Inversion; Monte Carlo Simulations; Depletion Stabilization; Correlation Attraction; Colloid stability;

    Abstract : The issue of controlling the stability between colloidal particles in solution is important, at least for industrial applications, relying on efficient flocculation or stable dispersions. The objective of this thesis is to shed some light on fundamental mechanisms behind the interplay between attractive and repulsive forces, in solutions containing colloids and polymers. READ MORE

  4. 2. Three dimensional mathematical modelling of pronuclei migration for the mouse

    Author : Sofia Tapani; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fertilisation process; pronucleus; dynamical simulation; SDE; correlation; CUSUM; microtubule; confocal microscopy; dynamical simulation;

    Abstract : The main question addressed in this thesis is what happens between the moment when the sperm enters the egg and the fusion of the male and the female pronuclei. Orientation of the apposing pronuclei most likely plays a decisive role in the polarity of the developing embryo. READ MORE

  5. 3. Stochastic modelling and analysis of early mouse development

    Abstract : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. READ MORE

  6. 4. Re-establishment of connectivity for fish populations in regulated rivers

    Author : Olle Calles; Larry Greenberg; Lars Nyberg; David Scruton; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attraction efficiency; Connectivity; Flow regime; Hyporheic water quality; Nature-like fishway; Passage efficiency; Regulated river; Remedial measures; Salmo trutta; Biology; Biologi; Biology; Biologi;

    Abstract : The hydropower industry has altered connectivity in many rivers during the last century. Many fish species depend on both an intact longitudinal connectivity to be able to migrate between spawning, feeding and winter habitats, and vertical connectivity for development and survival of incubating embryos and larvae in the gravel.

  7. 5. Biophysical studies on aggregation processes and amyloid fibrils with focus on Alzheimer's disease

    Author : Niklas Bark; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fluorescence correlation spectroscopy; amyloid fibril formation; Alzheimer s disease;

    Abstract : Alzheimer's disease (AD) is a fatal neurodegenerative disease, and is the most common form of dementia, affecting 1-2% of the population in industrialized countries. It is believed that intermediate species formed during amyloid Bpeptide (AB) polymerization play a key role in the pathogenesis of AD, but it is not known how such toxic effects are exerted. READ MORE
