Opis:: The paper presents results of air movement observations inside a cow barn (Fermbet construction type) adapted for a loose housing system. The conducted experiments made it possible to determine directions and characteristics of ventilated air flux in selected areas of the building as well as mark out areas where air stood still. In addition, the study offers recommendations regarding effective ventilation systems in the occupied zone under no-wind conditions.

Opis:: The paper covers research on physiographic features and anthropogenic factors influence on natural pond water storage. The problem was investigated both at the level of the Dopływ spod Nowej Wsi catchment (27.53 km2) and the smaller spatial unit Bagna Ramuckie natural pond (12.4 ha). Dynamics of physiographic features, changes of hydrographical network and anthropogenic factors including water, land and forest management practices were investigated. The decisive factor modulating processes of water storage rebuilding for investigated spatial units seems to be dynamics and long-term directional changes of air temperature. Rebuilding of pond water storage occurred after a 40-year period of air temperature decrease and the decline of water storage after a 20-year period of air temperature increase. Precipitation had minor significance in modulating pond water storage in long-term periods, because lack of long-term precipitation trends in analysed period. Although in short-term periods precipitation have important modulating impact on a decline of pond storage. The decline occurred after the dry period from 1989 to 1995 as a result of high deficit of climatic water balance. Spectacular rebuilding of pond water storage occurred in Bagna Ramuckie after the cold and wet period from 1956 to 1965. Non-climatic physiographic features and anthropogenic factors did not influence the processes of pond water storage rebuilding and decline because both of these factors seemed to be stationary over at least eight decades of 20th century, while processes of storage rebuilding or decline lasted over the investigated spatial unit.
