Abstract: The project listed in the acknowledgment focused on monitoring the occurrence of various fungus genera within building constructions of residential, non-residential and historic buildings. Fungoid organisms found on the indoor surface of building constructions create a serious aesthetic and constructional/structural disadvantage with an enormous impact on the interior environments exploitable space [2,3]. They can be found not only in rooms of old buildings, but also in newly built or reconstructed areas, where one would least expect them. Greater amounts of fungoid organisms occurring in artificial environments are harmful to humans. Therefore professional information provided to the public concerning their harmful impact not only on construction materials but also on human health, is very necessary.

Abstract: This work investigates agglomeration process of aerosol particles in presence of acoustic field. It is shown that besides orthokinetic and hydrodynamic interaction mechanisms, tribological interaction occurs in presence of acoustic field. This interaction depends on dynamic viscosity of the gas mixture above the liquid surface. The influence of acoustic field on tribological interaction between the aerosol particles was investigated both numerically and experimentally. The obtained results show the positive influence of acoustic field on agglomeration of aerosol particles.
