Examples of foaming

• In both cases, there was premature foaming, lowered surface tension and elevated rhamnolipid levels.

• The rapid viscosity decrease and rather small hydrogen diffusion coefficient at glass transition temperature result in "foaming" of beryllium hydride in the course of thermolysis.

• On detachment, biofilms were able to reform to former levels and at no time was foaming of the medium observed.

• This was accompanied by visible foaming of the culture medium.

• Foaming is often the result of lowered surface tension forces and is caused by the addition/release of surfactants to the liquid phase.

• Research also was begun on forming hollow polystyrene target shells by foaming filled granules overheated by water.

• The foaming glass of beer, also placed on the pedestal, suggests perhaps the indiscriminate judgement of men, who put beer and women in the same category.

• Except in some isolated circumstances there are now no serious problems of foaming.

• Some can even be caught foaming at the mouth.

• This should help a little to reduce foaming.

• I understand that the manufacturers are still trying to develop substances suitable for industrial use in place of those that mainly cause the foaming.

• Local authorities which try to break down this foaming agent are put to considerable expense.

• The idea that everyone is foaming at the mouth to get regional assemblies misreads the popular mood.

• A higher level of biodegradability would also reduce the likelihood of foaming in rivers, a phenomenon currently under investigation by the water research centre.

• If non-biodegradable substances are put into water, a very unpleasant foaming may occur—for example, at weirs and over patches of rough water.
