Pain avoidant behavior is a predictive factor for reduced function in children with persistent pain. A model to explain this is the Fear-Avoidance Model of Pain (FAM). In FAM pain-related fear plays an important role in the development and maintenance of avoidant behavior. The Fear of Pain Questionnaire-Child Report Short Form (FOPQC-SF) was developed to assess pain-related fear in children 8 to 1
We present three-dimensional measurements of particle-size-dependent acoustophoretic motion of micropar- ticles with diameters from 4.8 μm down to 0.5 μm suspended in either homogeneous or inhomogeneous fluids inside a glass-silicon microchannel and exposed to a standing ultrasound wave. To study the crossover from radiation force dominated to streaming dominated motion as the particle size is dec

Denna kurs handlar om fysikaliska frågeställningar inom biologin. Du kommer att lära dig om olika fysiska processer av biologisk betydelse, exempelvis slumpvandring och osmotiskt tryck, och hur de kan beskrivas teoretiskt med begrepp och verktyg som främst hämtas från statistisk mekanik. Kursen inleds med en kort introduktion till cell- och molekylärbiologi, riktad till fysiker och andra som inte

We developed an analytical theory for the many-body potential of mean force (POMF) between N spheres immersed in a continuum chain fluid. The theory is almost exact for a T polymer solution in the protein limit (small particles, long polymers), where N-body effects are important. Polydispersity in polymer length according to a SchulzFlory distribution emerges naturally from our analysis, as does t
Monte Carlo simulations show that charge-regulation alone can cause highly charged zirconium nanoparticles to adsorb to a similarly charged or neutral silica particle and thereby stabilizing the latter. This mechanism, referred to as halo stabilization, is quite general and applicable in a range of systems provided that pH, van der Waals forces, and dissociation constants of the charge-regulating
We use a continuum chain model and develop an analytical theory for the interaction between many spheres immersed in a fluid of ideal polydisperse polymers. Assuming local spherical symmetry of the polymer field about each particle, combined with a local approximation, compact expressions are derived for the many-body interaction between the spheres. We use a mean-field approximation to investigat
The microstructure evolution during cold rolling of commercial purity AA1050 aluminum is investigated through numerical simulations. A finite strain elasto-viscoplastic constitutive model is employed, where the dislocation density and average grain size are taken as variables characterizing the deformed microstructure. Grain size evolution due to dynamic recrystallization is considered and the mic
The pair interaction between two charged colloidal particles, in the presence of a polyelectrolyte as well as simple salt, is analyzed theoretically. Of particular interest is the way in which such a combination of salts can be used to induce a strong, long-range attraction, with at most a minor free energy barrier. We show that the nature of the simple salt is highly relevant, i.e., 2:1, 1:1, and
A direct numerical simulation (DNS) coupling with multi-zone chemistry mapping (MZCM) is presented to simulate flame propagation and auto-ignition in premixed fuel/air mixtures. In the MZCM approach, the physical domain is mapped into a low-dimensional phase domain with a few thermodynamic variables as the independent variables. The approach is based on the fractional step method, in which the flo
This study explores the concept of pasture, looking at how people classify it and the features that determine how an image is classified. The analysis is based on two parallel studies that used the same image material. The first study was a web-based survey in which respondents were asked to make a pairwise comparison of the images they felt best corresponded to pasture. The second study used eye-
Understanding the driving forces governing protein assembly requires the characterization of interactions at molecular level. We focus on two homologous oppositely charged proteins, lysozyme and alpha-lactalbumin, which can assemble into microspheres. The assembly early steps were characterized through the identification of interacting surfaces monitored at residue level by NMR chemical shift pert
This work deals with inverse-motion-based form finding for electroelasticity. The inverse motion problem is formulated for the electroelastic case, and the resulting equations are implemented within a finite element framework. A four-field variational approach is adopted, taking into consideration the typically incompressible behavior of the elastomer materials commonly used in electromechanical a
A fully divergence-free method is proposed for generation of inhomogeneous/anisotropic turbulence with large spatial variation. The method is based on the method of Smirnov et al., which is known to violate the divergence-free constraint when spatial variation of turbulence is present. In the proposed method a vector potential field is introduced; by taking the vector curl of the potential field o
Effective pair potentials between charged colloids, obtained from Monte Carlo simulations of two single colloids in a closed cell at the primitive model level, are shown to reproduce accurately the structure of aqueous salt-free colloidal dispersions, as determined from full primitive model simulations by Linse et al.
