This master thesis deals with service quality monitoring in libraries and it focuses especially on the situation in university libraries. There are foreign tools described in this thesis, namely the American LibQUAL+® which uses user satisfaction surveys, and German Bibliothekxindex which compares libraries according to recieved statistical data. From the Czech environment there is an initiative of the National Library of the Czech Republic described, "Benchmarking of Libraries", which is based on the German Bibliotheksindex but it is not applicable in university libraries. The thesis includes a self made suggestion on how to monitor service quality according to both of the foreign tools which was also applied to a selected university library. The results of this research indicate that these foreign tools are applicable in the Czech Republic and that the selected university library provides services which its users are overall very satisfied with.

Increasing energy demand and various problems associated with fossil fuels such as environmental pollution, global warming and diminishing petroleum reserves have greatly stimulated production of fuels and chemicals from renewable sources. Lignocellulosic biomass has been considered as one of the potential sources for a variety of fuels and industrial chemicals. 5-Hydroxymethylfurfural (HMF) has been identified as an excellent platform molecule because it is a flexible intermediate for the synthesis of bio-renewable fuels and materials. HMF can be easily obtained from acid-catalyzed hydration of biomass-derived carbohydrates (hexoses) in various media. HMF can be converted to energy products such as 2,5-bis(alkoxymethyl)furans (BAMFs), monomers for high-value polymers such as 2,5-bis(hydroxymethyl)furan (BHMF), and valuable intermediates for fine chemicals. Recently, magnetic nanoparticle based catalysts attracted more attention due to their good stability and easy separation from the reaction mixture by a permanent magnet. This unique magnetic separation property makes MNPs more effective than conventional filtration or centrifugation as it prevents loss of the catalyst. This dissertation work focuses on, firstly, studying the effectiveness of silica coated magnetite (Fe3O4) nanoparticles MNPs supported with sulfonic acid groups (Fe3O4@SiO2-SO3H) on the dehydration of glucose to HMF. Secondly, preparing a cost-effective catalytic transfer hydrogenation system for the selective transformation of HMF into BHMF via Meerwein-Ponndorf-Verley (MPV) reaction over the copper iron magnetic catalyst supported on activated carbon in ethanol solvent with the absence of molecular hydrogen. Thirdly, producing alkoxymethylfurans (AMFs) which are considered a potential biofuels by using two-step sequential reactions with cheap heterogeneous zinc-iron oxides magnetic nanocatalyst for the hydrogenation of HMF to furfuryl alcohols in various alcohols solvents in the absence of molecular hydrogen followed by solid Brønsted acid catalyst for the etherification reaction of furfuryl alcohol derivatives. All prepared heterogeneous catalysts were characterized by FTIR, XRD, H2-TPR, XPS, ICP-OES, HRTEM-EDX, and N2 adsorption-desorption isothermal analyses (BET and BJH) and were tested for recyclability. The chemical products were identified by high performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and products quantities were calculated by using calibration curves of chemical standards. Various reaction conditions such as reaction temperature, reaction time, catalyst amount, and alcohol type were optimized.

Entwickelt 1999 von der Bertelsmann Stiftung und dem Deutschen Bibliotheksverband ist der Bibliotheksindex BIX eines der ältesten Leistungsmessungsinstrumente in der bibliothekarischen Welt. Jedes Jahr beteiligen sich rund 250 Bibliotheken am BIX. Sie nutzen die Ergebnisse, um ihre Dienstleistungen zu vergleichen und sich der Öffentlichkeit zu präsentieren. Der BIX ist ein Steuerungsinstrument und dient als Grundlage für Managemententscheidungen und trägt so zur Leistungssteigerung bei, die wiederum allen Bürgerinnen und Bürgern zugutekommt.
