Posouzení faktorů ovlivňujících koncentraci prachových částic při lisování píce
ŠŤASTNÝ, Vladislav
The objective of this diploma thesis is to assess the factors affecting the concentration of dust particles during forage pressing. For this purpose, five presses for square bales and five presses for round bales were selected. They were harvesting different kinds of straw. Thanks to measurement using an aerosol monitor, the concentration of dust particles during the harvest was detected. The measured values were evaluated and the amount of concentration of the dust particles between the square and round bale presses was compared. There were also set the methodological steps of the measurement procedure.

Ventilation systems for agricultural buildings
ZDENĚK, Jakub
Theoretical part of my bachelor thesis deals with the description of ventilation systems and their certain parts used in agricultural objects. Practical part focuses on the description of post harvest line and possibilities of its ventilation system. Description and alterations were made for post harvest line Pluhův Žďár. The thesis analysis the current filter system and its alteration. There are parameters of both filter systems compared and evaluated in conclusion.

The influence of the ionization on the air dustiness in the pig weaners
MATĚJKOVÁ, Eva
The observation was performed in brick building for the pig weaners. The stabling was created as group litter pens. The porkers was batten on fodder. The aim of the work was evaluationed microclimate of stable and the influence of the ionization on the air dustiness. The temperature, the relative humidity, the rapidity of atmospheric circulation, the cooling-down temperature and dustiness was measured in the pig house. The ionization was practised in stable and than was evaluation the influence of the ionization on the air dustiness. From the measurement was found out, that the ionization of the air was positive affect low particle concentration of dust. Effect of the ionization on the air was the highest during feeding-time.
