The extremely important discovery of Joliot and co-workers (1969) showed that after several minutes dark incubation of unicellular algae suspensions or of isolated chloroplasts, the first flash does not lead to oxygen evolution, and the yields from the succeeding flashes show damping oscillations with a maximum after the third flash and a periodicity of four flashes. These results were used by ...

Because micro-ions accumulate around highly charged colloidal particles in electrolyte solutions, the relevant parameter to compute their interactions is not the bare charge, but an effective ~or renormalized! quantity, whose value is sensitive to the geometry of the colloid, the temperature or the presence of added-salt. This nonlinear screening effect is a central feature in the field of coll...

An articulated vehicle suspension comprising a parallel combination of energy restoring and dissipative elements and a feedback controlled force generator is analyzed using Linear Quadratic Gaussian (LQG) control technique. Ari ideal active suspension scheme is formulated to minimize a quadratic performance measure comprising ride quality, cargo safety, suspension and tire dynamic deflections, ...

We investigate ergodic theory of Poisson suspensions. In the process, we establish close connections between finite and infinite measure preserving ergodic theory. Poisson suspensions thus provide a new approach to infinite measure preserving ergodic theory. Fields investigated here are mixing properties, spectral theory, joinings. We also compare Poisson suspensions to the apparently similar l...

this work investigates the response of two-dimensional, turbulent boundary layer characteristics over a flat plate to the presence of suspended particulate matter. both phases are assumed to be interacting continua. that is, the carrier fluid equations are considered to be coupled with the particle-phase equations. a finite-difference technique with non-uniform grid has been employed for the so...

This paper reports the first study on the large amplitude oscillatory shear flow for magnetic fiber suspensions subject to a magnetic field perpendicular to the flow. The suspensions used in our experiments consisted of cobalt microfibers of the average length of 37 μm and diameter of 4.9 μm, dispersed in a silicon oil. Rheological measurements have been carried out at imposed stress using a co...

This work presents the results of experimental and theoretical study static pull-in tilting actuation executed by a hybrid levitation micro-actuator (HLMA) based on combination inductive electrostatic actuation. A semi-analytical model to such phenomenon is developed, for first time, as result using qualitative technique Lagrangian approach analyze contactless suspensions recent progress in cal...
