  1. 1. Collective behaviour in suspensions of pushers and pullers

    Master-uppsats, Lunds universitet/Biofysikalisk kemi

    Författare :Shan Anjum; [2019]
    Nyckelord :biophysics; active matter; collective motion; microswimmers; biohydrodynamics; non-equilibrium physics; low reynolds number physics; biophysical chemistry; biofysikalisk kemi; Physics and Astronomy; Chemistry; Technology and Engineering;

    Sammanfattning : Microswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. LÄS MER

  2. 2. Formation of Monolayered Phospholipids using Molecular Dynamics

    Kandidat-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Rebecka Lexelius; [2018]
    Nyckelord :phospholipids; lipids; DPPC; monolayer; molecular dynamics; MD; molecular dynamics simulation; GROMACS; biological membrane; lipid concentration; biophysics;

    Sammanfattning : The very fundamental properties of biological membranes can be understood by studying their formation. This sets a good foundation for research related to how the membranes interact with organic molecules and ions; something of great value in the quest of explaining transport phenomena through cell membranes.

  3. 3. Numerical model of the myosin V molecular motor

    Uppsats för yrkesexamina på avancerad nivå, KTH/Lärande

    Författare :Gustav Sollenberg; [2018]
    Nyckelord :Numerical model; myosin V; simulation; biophysics; didactical engineering; Numerisk modell; myosin V; simulering; biofysik; didaktisk ingenjörskonst;

    Sammanfattning : A variation on a numerical model of the motor protein myosin V presentedin a paper by Craig and Linke (2009) is developed. An alternative potential is proposed. All aspects of the model development arederived in detail and tested. Two model tests are created and used toconfirm the correctness of the developed model. LÄS MER

  4. 4. Handling of long DNA - applications and polymer physics

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Alexandra Kühnlein; [2016]
    Nyckelord :Biophysics; microfluidics; DLD; DNA; sorting; Physics and Astronomy;

    Sammanfattning : This thesis provides a proof of principle that deterministic lateral displacement (DLD) can be used to spatially separate DNA molecules by size. In order to achieve high separation quality, the pressure range, i.e. flow velocity has to be chosen carefully. LÄS MER

  5. 5. Describing radial patterning and leaf polarity in plants using a model of a dynamic shoot apical meristem with primordia initiation

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :André Larsson; [2012]
    Nyckelord :central; peripheral; miRNA; phyllotaxis; gene regulary network; plant; meristem; auxin; PIN1; REVOLUTA; KANADI; computational physics; biophysics; Arabidopsis; radial patterning; leaf; polarity; self-activation; feedback; Physics and Astronomy;

    Sammanfattning : The initiation of leaf and flower primordia in plants occurs in the shoot apical meristem and results in visible large–scale regular patterns of organs. It has previously been proposed that the initiation of new primordia is triggered by the plant hormone auxin by a mechanism that is confined to the outermost epidermal layer of the meristem. LÄS MER
