The article summarizes the principles and methods of measurement of beer foaming power including kinetic equations describing foam disintegration. Foaming power a complex quality parameter comprising of several aspects, such as foam stability, its appearance, structure, its capability of clinging to a glass and resistance against negative effects. The foam appearance and structure also depend on the way of foam formation, for example pouring of beer from a bottle or draft. For these reasons, there is no universal method for foaming power measurement and such method should be chosen for the measurement that would give a true picture of the property...

Oceans cover some 3 quarters of the Earth's surface and play an important role in water and mineral element cycling as well as in the global climate change. The main consequences of the recent temperature increase include sea level rise due to both glacier melting and volume expansion. The role of oceans in absorbing considerable part of the CO2 from the atmosphere is also important. Huge amounts of methane hydrates recently found on the seabed could contribute to the energy supply but also to an abrupt atmospheric increase in the concentration of the green house gases. Paradoxically, the potential melting of the Greenland ice sheet could...
