Use of LCA (life cycle assessment) in environmental sciences
Francová, Michaela ; Ettler, Vojtěch (advisor) ; Vítková, Martina (referee)
The goal of this bachelor thesis is to describe the analytical method called the Life Cycle Assessment (LCA) and to show its practical applications in case studies especially in waste management. The LCA method consists of four phases. The first phase is the definition of the intention and volume of the study, which includes the subject, the recipient, the place concerned and the purpose of the study together with specifications of the scope of product system. The second phase deals with the life cycle inventory. The investigators collect the accessible data on individual inputs and outputs of the product system, which are consequently embedded into the inventory chart. The third phase applies to the assessment of the life cycle impact on predefined categories using the impact categories indicators. The final phase summarizes the interpretation of the life cycle, its intelligibility for the submitter being mainly considered.

Methodology for separation and isotope analysis of magnesium in selected geomaterials
Francová, Michaela ; Farkaš, Juraj (advisor) ; Chrastný, Vladislav (referee)
An efficient methodology for separation of magnesium from different geomaterials was developed in order to determinate their isotopic composition. This methodology with 100% yield is suitable for high precision analysis of Mg isotopes by multi collector inductively coupled plasma mass spectrometry (MC-ICP-MS). Three separate stages of ion-exchange chromatography were carried out in ultra-trace laboratory equipped with laminar flowbox using cation exchange resin, AG50W-X12 and chemicals of ultrapure quality. Variations in samples 26 Mg/24 Mg and 25 Mg/24 Mg ratios are expressed as δ26 Mg and δ25 Mg units, which are deviations in parts per 103 from the same ratio in DSM3 Mg standard. The robustness of the technique was assessed by replicate analyses of magnesium standards Cambridge 1 versus DSM3. The long term repeatability of the Mg isotope ratio measurements of Cambridge 1 against DSM3 using this technique is -2.577 ± 0.10‰ on δ26 Mg and -1.328 ± 0.06‰ on δ25 Mg at 95% of confidence (2σ). Delta 26 Mg in five natural standard samples was measured in order to validate a quality of measurement in two different laboratories: Czech Geological Survey, Prague, Czech Republic and GFS Potsdam, Research centre for geoscientist, Potsdam, Germany. The results measured in this study (laboratory of CGS) are...

Marketing strategy of the non-profit organization People in Need
Francová, Michaela ; Lhotáková, Markéta (advisor) ; Král, Petr (referee)
The main objective of this bachelor thesis is to propose the improvement of the marketing strategy of the non-profit organization People in Need. This thesis focuses on one specific product that this particular organization offers - the Real Gift. The secondary objective consists of a detailed study of available literature on this topic, including scientific articles that explain non-profit marketing strategies. The theoretical part explains the typical characteristics of non-profit organizations, their financing and marketing activities. Theoretical findings are applied to a specific organization. In the practical part I apply the questionnaire method to determine the current marketing situation and based on the results obtained, I suggest means for improving communication with the target group. The conclusion includes further recommendations for possible improvements based on the research results from the questionnaire.
