AN INTRODUCTION TO SURFACE-FREE BEHAVIOUR

Ergonomics, 1964
The motions of the weightless Free-floating worker are discussed. Study techniques include physical analyses of the motions, inflight validation of the analyses, and mathematical projections of probable orbital motions. Sensations arising from these motions are also discussed.

Negative phototactic behaviour of crystals on a glass surface

Chemical Communications, 2019
We demonstrate that visible light irradiation can drive negative phototactic behavior of azobenzene crystals, which have an amoeba-like crawling motion.

Numerical Simulation of Mechanical Behaviour of Textile Surfaces

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000
AbstractThe paper presents a model which can be used for calculations of complex mechanical behaviour of textile surfaces e.g. surfaces obtained from a drapemeter. Fabric is treated an this model as a two‐dimensional continuum. As kinetic and kinematic measures are used these of the Cosserat continuum. Linear elastic, orthotropic constitutive equations

The behaviour of films on sliding surfaces

Wear, 1964
Abstract The ways in which surface films on metals can affect seizure, pressure welding, sintering, friction and boundary lubrication are discussed.

Dynamic Behaviour of Solid Surfaces

1977
The investigation of the kinetics of heterogeneous isotopic exchange in systems like NaI/CH3 * I provides information about the dynamic behaviour of the surface of ionic crystals. The number of surface layers taking part in fast exchange as well as their mobility increases sharply with temperature.

The Boundary Behaviour of Minimal Surfaces

2010
This and the next chapter deal with the main topic of Vol. 2, the boundary behaviour of minimal surfaces, with particular emphasis on the behaviour of stationary surfaces at their free boundaries. This and the following chapter will be the most technical and least geometric parts of our lectures. They can be viewed as a section of the regularity theory

Statistical behaviour of surface profiles

Wear, 1971
Abstract Since the surface profiles obtained by stylus instruments may be considered as a random process, it is possible to represent these profiles by statistical parameters and functions. The usual geometrical parameters from surface profiles used for the specification of roughness do not completely give the nature of the profile.

Foaming behaviour and dynamic surface properties of liquids

Current Opinion in Colloid & Interface Science, 1998
A growing interest has occurred in the physical mechanisms that are involved in the the various aspects of foaming behaviour such as foam making (overrun and bubble size distribution) and foam keeping (drainage, coalescence and Ostwald ripening). It has recently been shown that dynamic surface properties, both close and far from equilibrium, play an ...

Surface forces and colloidal behaviour

2019
The landmark DLVO theory of colloid stability sought to explain the stability of lyophobic colloids in terms of the interplay between attractive dispersion forces, and repulsive electrical (Coulombic) forces between particle surfaces. The net interaction energy between two particles (resulting from these so-called surface forces) as a function of ...
