Study of temperature factor in gradient and isocratic HPLC separation
Habart, Miroslav ; Nováková, Lucie (advisor) ; Chocholouš, Petr (referee)
5 Abstract This thesis was focused on the determination of the temparature influence upon analysis of phenolic acids and fluoroquinolone antibiotics using high performance liquid chromatography. Analysis was performed on Zorbax SB C18 (50 x 4.6 mm; 1.8 µm) analytical column using ultra - viollet detection (UV) for both phenolic acids and fluoroquinolon antibiotics. The optimization of separation conditions was carried out for determination of phenolic acids and fluoroquinolone antibiotics. The effect of composition and concentration of aqueous part of mobile phase and especially the effect of temperature was investigated. The gradient elution was used for determination of phenolic acids. The mobile phase was formed by 0.1% formic acid and methanol. The isocratic elution was used for determination of fluoroquinolone antibiotics and the mobile phase was also formed by 0.1% formic acid and methanol. Accelerating of analysis and saving time and used solvents by using higher temperature were the main goals of this thesis. This premise came true in the analysis of phenolic acids. The analysis was faster with good peak resolution. The results for fluoroquinolone antibiotics were not better than basic 25žC measurement. Contrariwise, lower than laboratory temperature was more advantageous for their analysis. System...

The aim of this thesis is to analyze the learning and development system of managers in the company Konštrukta Industry, to evaluate this system and suggest recommendations to solve the problems. The thesis is divided into six chapters. In the first one i speak about human resource development in general, whom to develop, how, in what part and how can we motivate people, how can we make them to want to develop themselves. The second chapter is dedicated to the enterprise educational system, what are its goals, advantages. Then I describe its phases, which are educational needs identification, planning, realization and the last but not least results and efficiency evaluation. The end of this chapter is about several methods of learning and development, which are mentioned in present literature and praxis. The third and the last chapter of the theoretical part contains detailed information about managerial learning and development, where I also describe manager in general, his competences, competence model and then the main approaches and parts of the entire development process of managers. In the firs chapter of the practical part I introduce the company I co-operated with. In the next chapter I describe the system of learning and development of its employees and managers in particular. In the end of this thesis I give them some recommendations, how could they improve in the area of learning and development of their managers.

Arabs in Teplice. Interactions between Czechs and Arabs from the Perspective of Czech Native Speakers
Kantarová, Kateřina ; Nekvapil, Jiří (advisor) ; Čmejrková, Světla (referee) ; Kropáček, Luboš (referee)
The thesis deals with Czech-Arab interactions from the perspective of Czech native speakers, namely with the analysis within the work communication domain. It briefly introduces the situation of the Arab community in Teplice and the specific conditions related to the presence of Arab clients in Teplice Spa. The thesis applies the Language Management Theory which focuses on real interactions as sources of language problems. Interactions between employees of company A and their Arabic communication partners are the objects of the empirical research. Through interaction interviews the stages of language management process are analysed on the language, communication and sociocultural level. The aim of the study is to provide an authentic picture of intercultural interactions and to identify the real problems which the participants solve. Data analysis revealed that Czech native speakers showed a greater degree of tolerance for language deviations and adjustment designs which was due to the application of contact norms. When evaluating and creating plans on the communication and sociocultural level the Czech native speakers applied internal norms which resulted in numerous negative evaluations and mostly zero adjustment designs. The thesis points to the advantages and limitations resulting from the application...

Relaxed rebalancing of binary search trees
Kříž, Martin ; Koubek, Václav (referee) ; Koubková, Alena (advisor)
In standard binary trees the rebalancing is carried out in connection with and immediately folowing the updates. Relaxed balancing allows to separate updates and rebalancing. First advantage of this approach is to keep the tree partially unbalanced and leave rebalancing to the different time when system is idle. Other great benefit of presented relaxed balancing algorithms in concurrent enviroment is necessity of keeping only small constant number of locks for modifying operations and thus allowing more modifying operations in the tree at the same time. The aim of this thesis is to empirically compare standard and relaxed variant of AVL tree in several different scenarios in concurrent enviroment according to number of data compares, number and type of rotations and according to the time requirements.

IFRS 4 Insurance Contracts Phase II - Current Situation and Outlook
Ochman, Daniel ; Bokšová, Jiřina (advisor) ; Kolář, Jakub (referee)
This thesis deals with phase II of IFRS 4 Insurance contracts. The aim of the standard is to establish the principles that an entity should apply to report useful information to users of its financial statements about the nature, amount, timing and uncertainty of cash flows from insurance contracts, so that the financial statements of the entity are comparable with financial statements of other entities. Therefore IASB introduced building blocks measurement model, where an insurance contract is measured based on the present value of expected fulfillment cash flows, risk margin and contractual service margin. The building blocks model is based on making extensive judgments when measuring the insurance contracts. To explain the judgments, the standard requires the entity to disclose details about the judgments in the footnotes to the financial statements. The building blocks model is used mainly for life insurance contracts. For contracts that last one year or less (usually non-life insurance contracts) the standard allows the entities to use a simplified approach for measuring insurance contracts that is similar as the current practice of measuring non-life insurance contracts. Revenues from insurance contracts should depict the transfer of promised services arising from the insurance contract in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those services (this approach is in line with the prepared IFRS 15 Revenue from Contracts with Customers).
