Reactions of Alkenes Iniciated by Transition Metals Alkyls and Hydrides
Nečas, David ; Kotora, Martin (advisor) ; Jindřich, Jindřich (referee) ; Starý, Ivo (referee) ; Mazal, Ctibor (referee)
l0 5. Conclusion 1) The first and practical catalýic method for smooth deallylation of 2-substituted-2-allylmalonates to 2-substituted malonates via selective cleavage of the C-C bond under mild reaction conditions has been developed' The reaction seems to be general with respect to the transition-metal complexes; however, the comparison of Ru and Ni catalysts indicates considerable differences in their specific activity and selectiviý. Last but not least, the smooth deallylation offers an opportuniý to use the allyl group as an effective protective group for acidic hydrogen of malonic esters. 2) It has been shown that it is possible to re-route the course of the reaction from c{ bond cleavage (deallylation) to c{ bond formation (cyclization) in Ni hydride cataryzed, reactions by a change in the amount of organoaluminium. It proceeded in high yields even in cases where deallylation could compete with cyclization (e.g. diallylmalonate, etc.) in high selectiviý. In addition, generation of Ni hydride species in sinr provides an effective means for fast and selective cyclization of variously substituted 1,6- heptadienes to cyclopentanes. Moreover, it is possible exert certain level of control for the preferential formation of methylidene(methyl)cyclopentanes or cyclopentenes by the appropriate choice of thb...

Brand launch of a feminine fashion brand in the Czech Republic
Šuchmová, Pavla ; Postler, Milan (advisor)
This master thesis "Brand launch of a feminine fashion brand in the Czech Republic" provides a market analysis, which is antecedent to a brand launch. The main goal of this thesis was to answer, whether the particular fashion brand is interesting for Czech female consumers and whether the Czech market is interesting for the brand. The respective brand Friis & Company offers ultra-feminine and latest trends accessories and wants to provide their customers with "a bit of luxury for every day". The target group of the brand are young women in the age of 15 to 35. The master thesis is divided into two main parts -- a theoretical part and a practical part. The theoretical part discusses, among others, the main trends and specifics of the fashion business, specifics of women's purchase decision-making and the relation of women towards fashion. The practical part introduces the brand and provides the following analyses: PEST analysis of the Czech market, analysis of consumer behaviour of young Czech women in relation to fashion accessories, analysis of fashion brands present at the Czech market and a test of the brand's concept on Czech female consumers. A large part of the practical section of the master thesis is based on own survey.

Suffix Array for Large Alphabet
Šesták, Radovan ; Senft, Martin (referee) ; Lánský, Jan (advisor)
Burrows-Wheeler Transform (BWT) [3] is used as the major part in block compression which has good balance of speed and compression ratio. Suffix arrays are used in the coding phase of BWT and we focus on creating them for alphabet larger than 2^8 symbols. The motivation for this work has been software project XBW[4] - an application for compression of large XML files. The role of BWT is to reorder input before applying other algorithms. We describe and implement three families of algorithms for encoding. First is inspired by the work of Sadakane [10] and further improved by Larsson [8]. Second family includes algorithm by Seward [11] and algorithm by Itoh further improved by Kao [5]. Finally we present algorithm by Kärkkäinen and Sanders [6] for constructing suffix arrays in linear time.

Pavlíková, Jana ; Beroušek, Petr (advisor) ; Šikýř, Martin (referee)
The aim of the thesis is to analyze the system of management education in Trial bank, to evaluate this system and recommend the firm some changes in the educational system, which would lead to reduction of pitfalls in this area, eventually, would help to achieve better results from the educational process. First chapter contains general characteristic of managerial work and competencies and the best practice used for creating a competency model. The second part is dedicated to the theoretical knowledge of the educational methods that are commonly used for training of managerial skills. The third part is an overview and evaluation of educational and development activities and its efficiency. The fourth chapter consists of analysis of an educational system of managers in Trial bank, describes company internal policy and offer of the educational programs for its employees. In the last chapter are stated conclusions and recommendations I came to, which could the company apply in order to improve contemporary educational and development system for its employees.

Acquaintanceship of the catholics with the problem of assisted reproduction
Daly, Jana ; Ovečka, Libor (advisor) ; Skoblík, Jiří (referee)
How informed are Catholics about assisted reproduction Infertility is on the increase and alongside this problem thre has been a growth in the number of clinics offering assisted reproduction mainly in the developed world. More and more people who are unable to give birth naturally are deciding on artificial insemination. The goal of this thesis was to find out the standing of the Catholic people with regards to this phenomenon, how much they are aware of it, what is the source of their knowledge and how much they agree with the church's teaching. The first part introduces the techniques of reproductive medicine and, in particular, their negative circumstances. The following part describes the research whose focus was groups of Catholics in Prague, outside Prague and also students at theological colleges. Its results to a large extent answer the questions that the author asks herself in the introduction. KEYWORDS: Assisted Reproduction, Artificial Insemination, Catholics, Embryo, Infertility.

Optimization of costs in transportation company JOLLY trans, s. r. o.
Válek, Libor ; Novák, Radek (advisor) ; Rathouský, Bedřich (referee)
The Master´s Thesis deals with analyze of total costs in transportation company JOLLY trans, s.r.o., where these costs are divided into operational and financial. This thesis is preparing data for a pricing of the transportation. Operational costs are divided into salary for driver, fuel and much more, there are a lot of hidden charges, that affect the final price of transportation. Financial costs are one of the highest costs in company accountancy, because this costs include purchase of a truck and semitrailer. This thesis focus on optimization of this financial costs to save the money. Main goal of this Master´s Thesis is to set the minimal price that transportation company is able to offer to the customer to take profits. And then suggest how to cut the costs to realize higher profit.

Attention is being paid particularly to the method chosen by Sontag of displaying the wartime suffering. The thesis also presents the literary works of Susan Sontag and her relationship to film, and offers an insight into the situation during the Yom Kippur War.

Impact of cryogenic grinding on iodine homogeneity in NIST SRM 1548a Typical Diet
Kameník, Jan ; Kučera, Jan
The reference material NIST SRM 1548a Typical Diet has a certified iodine mass fraction of 0.759±0.103 mg kg-1. The expanded uncertainty is rather large (relative value 13.6 %), thus the material does not provide strict requirements for quality control results. Milling of NIST SRM 1548a at the temperature of liquid nitrogen yielded free-flowing material. Iodine mass fraction in the original and cryo-ground materials was determined by epithermal neutron activation analysis (ENAA) and radiochemical neutron activation analysis (RNAA). The average and standard deviation from both methods was 0.73±0.03 mg kg-1 (20 values). The determined mass fraction was in a close agreement with the certified value of NIST SRM 1548a, thus iodine total content was not influenced by the milling procedure. In comparison to iodine mass fraction determined in the original NIST SRM 1548a 0.72±0.07 mg kg-1 (average ± standard deviation, 14 values), the standard deviation for cryo-ground material was considerably lower. The prepared quality control material sets up more stringent requirements on the validation and quality control procedures of the measurement of iodine mass fraction in such a composite food matrices. We believe that the iodine random inhomogeneity in the original NIST SRM 1548a is due to insufficient mixing of some iodine-rich component in the complex food matrices. Milling at the temperature of liquid nitrogen offers an effective option for production of future reference materials of this kind.
