Various methods of soil transfer and inoculation in restoration ecology
Hurychová, Hana ; Frouz, Jan (advisor) ; Roubíčková, Alena (referee)
Soil translocation is a method used in restoration ecology to either salvage habitats threatened by human activity or to restore disturbed habitats. There are various factors affecting the success rate of translocation operations which include the proper selection of a receptor site, method of soil manipulation, soil stockpiling and adequate aftercare. Different methods of soil stripping distinct in their success rates and application for use in habitat restoration, mainly in regards to their effect on the resultant community composition and financial costs. Translocations can result in decrease of biodiversity, but may be a viable option for locations of high conservation value where conservation in situ is not possible, allowing for quick restoration of mature ecosystems. Thorough surveys prior to and after the operation and sufficient allocation of resources are a key factor for successful translocation of soils and the associated biota. Additional research in the fields of invasions, comparison of methods and data analysis of translocation projects may improve the utilization of this technique in the future.

Study of static and dynamic flow properties of pharmaceutical excipients
Hurychová, Hana ; Šklubalová, Zdeňka (advisor) ; Vetchý, David (referee) ; Zámostný, Petr (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department: Pharmaceutical Technology Candidate: Ing. Hana Hurychová Supervisor: doc. PharmDr. Zdeňka Šklubalová, Ph.D. Title of Doctoral Thesis: Study of static and dynamic flow properties of pharmaceutical excipients Flow properties are among the most significant characteristics of pharmaceutical materials. Recent modern technologies allow preparation of particles with modified surface properties and flow behaviour for the conventional as well as new excipients. In this work, the static (compressibility index, Hausner ratio, angle of repose, shear testing) and dynamic (flow rate, avalanche testing) flow properties of a wide variety of excipients, their particle size fractions and selected model mixtures were evaluated. In particular, attention was paid to modelling of the flow rate by the equation prospectively suitable for use in the standardization of flow testing in pharmaceutical technology. The power equation in which the equation parameter is a direct prediction of the flow rate through an orifice having a unit diameter is recommended. The basic granulometric characteristics of particles were completed with the particle fractal dimension (pDF) and the bulk fractal dimension (bDF). Although a relatively strong correlation between the...
