1. 1. Diel vertical migration in marine dinoflagellates

   Författare :Therese Jephson; Enhet akvatisk ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Key words: diel vertical migration; DVM; dinoflagellates; stratification; halocline; thermocline; behavior diel vertical migration; behavior;

   Sammanfattning : Increasing precipitation and surface water temperature due to global change may strengthen stratification in coastal regions, which could influence the behavior of dinoflagellate diel vertical migration (DVM). DVM is a behavioral mechanism by which dinoflagellates can access photosynthetically active radiation near the surface, and nutrients at depth. LÄS MER

4. 3. Storage Stability and Phase Separation Behaviour of Polymer-Modified Bitumen : Characterization and Modelling

   Författare :Jiqing Zhu; Niki Kringos; Dallas Little; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer-modified bitumen; Storage stability; Phase separation; Fluorescence microscopy; Phase-field modelling; Polymermodifierad bitumen; Lagringsstabilitet; Fasseparation; Fluorescensmikroskopi; Fas-fälts modellering; Transportvetenskap; Transport Science;

   Sammanfattning : Polymer-modified bitumen (PMB) is a high-performance material for road construction and maintenance. But its storage stability and phase separation behaviour are still not sufficiently understood and need to be studied toward a more successful and sustainable application of PMB. LÄS MER

5. 4. Neural limits of visual resolution

   Författare :Zoran Popovic; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell separation; cortical magnification; detection; estimated receptive field; high-pass filtered optotypes; nyquist limit; psychophysics; resolution; ganglion cells;

   Sammanfattning : Aims: The aim of this thesis was to formulate a model of retinal neural circuitry in humans based on morphological estimates of retinal cone and ganglion cell populations, to compare results based on this model to psychophysical measurements of visual resolution and identify the retinal neural factors that limit visual resolution.Materials & Methods: Total displacement of central ganglion cells from foveal cones was obtained by estimating the length of fibers of Henle in four human retinas along the nasal or vertical hemi-meridians.

7. 5. Microfluidic Cell and Particle Sorting using Deterministic Lateral Displacement

   Författare :Stefan Holm; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Separation science; Deterministic Lateral Displacement; Cell analysis; Deterministic lateral displacement; Microfluidics; Particle sorting; Droplet microfluidics; trypanosomiasis; red blood cell; Cell sorting; Fysicumarkivet A:2018:Holm;

   Sammanfattning : Microfluidics is a field which has the potential to revolutionize medical diagnostics. The ability to sort and analyse cells by the use of portable handheld devices has the potential to enable sensitive devices for point-of-care diagnostics. LÄS MER
