Flame Surface Density Measurements and Curvature Statistics for Turbulent Premixed Bunsen Flames
… Flame topography measurements in terms of flame surface density and curvature were calculated based on the flame front detected by the CH PLIF signal. The goal of this work was to investigate turbulent flames with extremely high turbulence intensity using a recently developed HiPilot burner (a …

The Effects of Bisphosphonates on Bone Remodeling: Analysis of Microdamage Targeting by BMUs, BMU Velocity and Crack Surface Density
… and osteonal area while increasing crack surface density in a dose-dependent manner. Thirty-six rib bone samples were obtained from the Indiana University School of Medicine from a three year canine study in which skeletally mature beagles were administered the bisphosphonate Alendronate …

Development of a 20-moment Polydisperse and Polykinetic Spray Model Coupled With a Surface Density Approach for the Modelling of the Dense and Disperse Liquid Spray Regimes
… used to obtain the droplet probability density function (PDF) are either empirically-based algebraic models or DNS-type approaches with very large computational cost. The Sigma-Y model employs an assumption similar to the Kolmogorov hypothesis which assumes that the large and small-scale …

Trafficking motifs in potassium channels
… important potassium ion channels alter their surface density leading to disease. Therefore, it is of fundamental importance to investigate the trafficking mechanisms that regulate the surface density of these channels. Techniques in cell biology, molecular biology and biochemistry were …

Optimizing the Toehold-Mediated Strand Displacement Reaction on the Nanoparticle Surface by Altering the Surface DNA Density for the Design of a microRNA NanoOptical Sensor
… strand-displacement reaction on nanoparticle surfaces. Gold nanoparticles were functionalized with oligonucleotide sequences with varying surface density by incorporating diluent DNA strands. The hybridization of DNA yields aggregates which then disassemble via a strand-displacement reaction …

Fokker-Planck models and globular cluster evolution
… are compared to star-count mass functions and surface density profiles for M71. It is possible to reproduce the tidal boundary and degree of mass segregation using these models but the central density profiles of the fitted models are much steeper than is observed. On the basis of the degree of …

Membrane trafficking of ATP-sensitive potassium channels
… is known how the number of channels at the cell surface is regulated. The number of channels in the plasma membrane could be regulated in two ways; firstly by regulating the overall population of channels within the cells by increasing/decreasing the rates of channel synthesis or degradation, and …

The star formation and dynamics of nearby galaxies
A scaling relation between the surface density of star formation and gas in the disks of galaxies has become the basis of our understanding of extragalactic star formation on scales of hundreds of parsecs and larger. This is an empirical law but star formation is a complex process - the presence of …

Functional analytic treatment of linear transport equations in kinetic theory and neutron transport theory
The temperature-density equation of Kinetic Theory and the conservative neutron transport equation are studied. In both cases a modified version of the Larsen-Habetler resolvent integration technique is applied to obtain full-range and half-range expansions. For the neutron transport equation the …
