Experiments on two-dimensional soap froth under temperature ramping have been performed. At constant temperatures, the classical linear dependence of the averaged cell area with time is observed at di8'erent temperatures. The rate of change of area depends sensitively on temperature. For froths under constant temperature ramping, in contrast to the classical results, a quadratic evolution of th...

Pyrrhotite-bearing aggregates are a major cause of internal sulphate attack (ISA) in concrete. The concentration pyrrhotite is usually too low to permit direct accurate quantification. Hence, safety restrictions put on expressed terms the total sulphur content. This paper outlines an analytical approach which froth flotation employed produce bulk sulphide concentrate amenable quantification pyr...

Froth flotation is an important mineral concentration technique. Faulty conditions in processes may cause the huge waste of resources and reagents, consequently, lead to deterioration terms benefits plants. In this paper, we propose a computer vision-aided fault detection diagnosis approach for froth flotation. Specifically, joint Gabor texture feature based on Copula model designed describe im...

The present study reports the case of a 43-yr-old very sporty male, who developed shortness of breath and expectorated bloody froth during aqua jogging. Pulmonary oedema was diagnosed clinically and by computed tomography of the chest. The patient made a full recovery and his echocardiography was entirely normal. Pulmonary oedema occurring in healthy scuba-divers and swimmers has been reported ...
