Simultaneous 3D measurement of the translation and rotation of finite size particles and the flow field in a fully developed turbulent water flow [PDF]

open access: yes, 2012
We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles together with the turbulent flow.

Effects of fluid flow rate and viscosity on gravel-pack plugging and the optimization of sand-control wells production

open access: yesPetroleum Exploration and Development, 2019
Series of experiments were performed to simulate the invasion of formation sand into and the plugging process of gravel-pack at different viscosities and flowing rates of fluid. Two types of formation sands with the medium size of 0.10 mm and 0.16 mm and

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]

open access: yes, 2016
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.
