Diffusion of cupric ions in humic gel
Kalina, Michal ; Gregorová,, Eva (referee) ; Klučáková, Martina (advisor)
The bachelor´s thesis deals with the study of non–stationary diffusion of copper (II) ions in humic gel. The objective of the study was to validate that the diffusion is influenced by the volume of cupric ions solution and by the length of tubes filled with humic gel. Diffusion was characterized by the value of diffusion flux and by the copper (II) ionic concentration profiles in humic gel. The data necessary for calculation were obtained by spectrophotometric measuring of the extracts of each slice after diffusion.

Numerické simulace teplotního a vlhkostního pole ve střešních konstrukcích
Šmiták, Jan
In this bachelor thesis are compared different types of roof structures, whose compositions are different in type and thickness of the used materials. Explained is here of thermal transfer and water vapor diffusion of the structures. By using numerical simulation of calculation software which is based on the finite element method, described temperature and moisture field in stable (stationary) conditions in different geometric and boundary conditions.
