The effect of fertilization by nitrogen on leaves of free amino acids in plants
Neuberg, M. ; Pavlík, Milan ; Balík, J. ; Kaliszová, R. ; Pavlíková, D.
The effect of different fertilization systems, especially CULTAN (Controlled Uptake Long Term Ammonium Nutrition), on levels of selected amino acids (alanine, glycine, serine, asparagine and glutamine) was investigated in this study. As modeling plant was used maize (Zea mays L.; hybrid Rivaldo) and levels of amino acid were measured by GC-MS. We found significant difference in the levels of certain amino acids. Concentration of alanine and glutamine was higher by treatment with urea ammonium nitrate solution (DAM 390) compared with individuals treated by ammonium nitrate.

The phosphorus role in plants
Pavlíková, D. ; Pavlík, Milan ; Balík, J.
Phosphorus play very important role in plant metabolism. It is active as energy transporter and important structural component. Phosphate is relatively unavailable to plant roots. Thus plants have evolved several strategies for obtaining P from the soil. They can modify root structure and function, excrete root exudates helping with solubilization of P compounds in root rhizosphere.

Wireless technology Wi-Fi
Chudomelka, Jan ; Pokorný, Pavel (advisor) ; Balík, Jindřich (referee)
This thesis describes a wireless technology Wi-Fi, its history, development and present state, different types of networks, security from the physical point of view and influence of the used frequency on the human organism. Furthermore, the possibility of using this technology commercially and noncommercially, EDUROAM academic network, including its access points in the world and the finding of some hotspots in the Czech Republic.
