The present paper is dedicated to numerical and experimental study of the hydrodynamic of a non-reactive isothermal pressurized fluidized bed. Experimental data have been obtained using PEPT technique allowing to track a particle trajectory inside a dense fluidized bed. A specific post-processing approach has been developed to compute the Eulerian time-averaged particle velocity field. The comparison with 3-dimensional numerical model predictions shows a good agreement in the core of the fluidized bed. In contrast, in the near wall region the numerical model overestimate the downward particle velocity. The modification of particle phase wall boundary condition improves the numerical predictions.

The paper provides data on the use of nanostructured cobalt sulfate in the production of marmalade as functional food for prophylactic purposes. The particle trajectory analysis method (NTA method) was used to determine the sizes of nanostructured cobalt sulfate. In this case, the smallest size (25.7 nm) is formed only in gellan gum with a “core : shell” ratio of 1:1. When the “core : shell” ratio in gellan gum is 1:3, the average size of nanocapsules is 49.9 nm. This result can be explained by the tighter packing of cobalt sulfate in the capsule. In sodium alginate, the average nanocapsule size is already 191 nm. The polydispersity coefficient in all studied shells and at different “core : shell” ratios are practically equal and amounts to 0.84–1.09, which corresponds to a spherical shape.

This Paper Discusses And Evaluates The Techniques And Technology Available To Reconstruct Shooting Incidents. Reconstruction Typically Involves Movement Of The Shooter(S), Their Gun(S), Victim(S), Vehicles, And Possibly Witnesses. The Analysis Involves Shooting Range Tests, Photogrammetry, 3-Dimensional Computer Modeling, Bullet And Shell Trajectory Analysis, And A Time/Space Computer Animation Analysis. The Bullet Trajectories Are Re-Created In 3-Dimensional Space And Evaluated With The Assistance Of A 3-Dimensional Computer Model Created Through Photogrammetry. Today S Technology Allows Engineers To Reconstruct Entire Shooting Incidents In A 3-Dimensional Time-Space Model Where All The Factors Involved In The Incident Can Be Analyzed. Three Case Studies Will Be Discussed.
