Quality of honey depending on processing technology
Fejt, Jaroslav ; Bušová, Milena (advisor) ; Luboš, Luboš (referee)
This diploma thesis is aimed at assessing the impact of using multiple technologies or practices on the quality of honey. The theoretical part includes a summary of the main methods currently used for assessing the quality of honey and/or establishing its origin. The suitability of the selected apicultural (beekeeping) technology, apiary placement, handling bee honeycombs and facilities for extraction of honey present the first condition for obtaining quality honey without pesticides, air pollutant microparticles, hazardous elements, microorganisms, volatile pollutants of coating substances, antibiotics, drugs used against varroa destructor parasites and their residues. There are mentioned all the known bactericidal and bacteriostatic properties of honey to help preserve its natural quality features without degrading changes.
In the practical part there are two groups of honey samples collected from own hives in 2015. Those were sent for analysis to the Institute of beekeeping in Dol (Czech Republic). In 2016, ten samples from beekeepers and ten from retail markets were used. Their partial analysis was carried out at the Department of Agricultural Product Quality. The samples were obtained in a conventional manner using modern honey extractors and in the second case by pressing. The above mentioned samples were tested for water content, HMF, conductivity, glucose, fructose, sucrose, starch and caramel colorants, titration factor, Fiehe´s honey violation by starch sugar or sweetener.

Possibility to use Coarse Woody Debris after renaturation
Hapštáková, Barbora ; Zímová, Kateřina (advisor) ; Luboš, Luboš (referee)
The aim of this work was to determine the objective possibilities for eventual utilization of timber felling process, incurred during the planned excavation of the woods before surface mining. The catchment area plan under consideration is located on the northeastern outskirts of the city Duchcov builds on the current mined deposit oxyhumolit in a former quarry Vaclav.
Acquired current knowledge about the usage of dead wood in ecosystems are the basis for the application of the proposal a new method of disposal of residues after deforestation before the actual mining raw material, leaving residues after felling in the area. This method was preferred over chipping or complete removal of material from the site. Total has been so designed three study areas on which will take place targeted gradual decomposition of dead wood, is wearing all issues that this process belongs.
The benefit of this work is the application of the proposed method of disposal of organic residues from logging, especially relatively large therefore based broukoviště Tim settlement habitats different species of invertebrates other species of animals, plants hub.
The proposed method offers the possibility of further long-term exploration of the site.
