1. Exocomets in the β Pictoris system
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Comets have been a source of fascination throughout the history of man. In recent years, advances in technology have opened up for the study of extrasolar objects, among them exocomets. The first exocomets were observed in the β Pictoris system almost 50 years ago and the system has been of interest ever since. LÄS MER
2. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.

3. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. LÄS MER
4. Tillväxt av parkslide (Reynoutria japonica Houtt.) vid varierande tillgång på vatten : En experimentell studie av sticklingar och rhizomer
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Invasiva främmande arter (IFA) har negativa effekter på biologisk mångfald och inhemska ekosystem. Parkslide (Reynoutria japonica Houtt.) är en svårutrotad IFA som har fått stor spridning i delar av Europa, och även i södra och mellersta Sverige, framförallt i kustområden. LÄS MER
5. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER
