    Stanovenie teploty vznietenia sena pre účely posudzovania rizík v stredných a malých poľnohospodárskych podnikoch
    (University of Zilina, 2022) Marková, Iveta; Giertlová, Zuzana; Hutár, Marek
    Hot surfaces are an integral part of the technological processes of agricultural crop processing. Hot surfaces' temperature, at critical points, may exceed their minimum ignition temperature. The article aims to experimentally monitor the behaviour of hay in the event of its exposure to radiant heat. The mentioned model is implemented using a hot-plate device. The hot plate has a defined temperature-time curve. Based on the temperature-time curve, the hot surface´s temperature is determined as the minimum ignition temperature of the examined hay sample. At the same time, the temperatures inside the tested material were monitored. The heterogeneity of these samples significantly affected the nature of thermal degradation of biomass samples. The hay ignition temperature (406 ° C) can serve as a tool to assess the risk of fire.

    Possibilities of using unmanned aerial vehicles in forestry and agriculture
    (University of Zilina, 2021) Ďatko, Ondrej; Kandera, Branislav
    This work analyzes the penetration of the aviation, forestry and agriculture sector and aims to present forestry and agricultural activities where there is the possibility of using unmanned aerial vehicles. In the first chapter, the work deals with the characteristics of unmanned aerial vehicles, remote sensing, forestry and agriculture. The second chapter deals with a particular analyzes of scientific papers, articles and internet research, and on the basis of these analyzes presents examples of activities in which unmanned aerial vehicles can be used. The third chapter provides an overview of technological and software equipment needed to perform such activities or aerial work. In the fourth chapter, through the practical part, work focuses on examining the use of the mid-class unmanned aerial vehicle model for the plant health analysis, while providing justifications and findings from the results. As part of the practical part, it also provides practical information for the individual steps during the planning and operation of flight. In the fifth chapter, the work briefly summarizes the information and results collected, from which it suggests some possibilities for the use of unmanned aerial vehicles, such as their use in the vaccination of foxes, and the recommended procedures for operating flights or aerial work.
