Preparation of cochenial carmine
Helceletová, Zuzana ; Hrdličková Kučková, Štěpánka (advisor) ; Čapek Adamec, Martin (referee)
The aim of this study was to prepare a red organic pigment named cochineal carmine. The pigment was made out of dried insect called Coccus cacti using historical recipe. Next goal was to detect carminic acid by infrared spectroscopy with Fourier transform (FTIR) in dried bodies of the mentioned insect, then in the pigment prepared from it and in the pigment that was prepared using extract called carminum rubrum. The other results of this work were the comprehension of the origin and preparation of carmine pigment and the identification of carminic acid in both prepared pigments.

Optimization of photochemical hydrogen peroxide preparation
Mesnerová, Iveta ; Čapek Adamec, Martin (advisor) ; Kotoučová, Hana (referee)
The thesis topic: Optimization of photochemical preparation of hydrogen peroxide for laboratory of inorganic chemistry Abstract: This Bachelor thesis deals with compound of hydrogen and oxygen, hydrogen peroxide. The theoretical part of thesis deals with basic physical and chemical characteristic of hydrogen peroxide, its preparation and last but not the least its production. The practical part of thesis deals with two main laboratoř preparations of hydrogen peroxide. First, from barium peroxide sequential reaction with hydrochloric acid, sulphuric, carbonate leader. Second, from anthraquinone dissolved in toluene by photochemical reduction isopropylalcohol and following oxidation mixture of air oxygen. The aim of thesis is implementation of those two methods, finding out the pros and cons and their comparison mainly from the point of preparation effectivness and possibility of use in laboratories of inorganic chemistry. Keywords: hydrogen peroxide, anthraquinone, photochemical reduction, toluene, isopropylalcohol

History of the Czech fencing since its beginning till 1938
Čapek, Martin ; Waic, Marek (advisor) ; Kolář, František (referee)
Title: History of the Czech fencing since its beginning till 1938. Objectives: Analyze historical development of the Czech fencing since its beginning to 1938. I would like to pay attention to the development of the Czech fencing federation, the most important results, the World fencing championship in Piešťany and also one of the greatest Czech club ČŠK Riegel. Methods: Most of the information I got in the National Archives in Prague. Moreover I got the publications and copies of magazines in the library of fencing club ČŠK Riegel, where they have history of their club in sheets from year to year. I used yearbooks and annual reports, where were reported the most important moments in the history of the federation. I also used the publications received from the Czech fencing association and publications dedicated to the sport of fencing in general. Results: The result is a comprehensive history of the Czech fencing till 1938. Keywords: Fencing, history, Czech fencing federation.

Identification of milk and collagenous binders used in colour layers in art works
Kofroňová, Pavla ; Hrdličková Kučková, Štěpánka (advisor) ; Čapek Adamec, Martin (referee)
The task of this diploma thesis was to investigate the influence of inorganic pigments on the identification of casein oil and animal glue tempera by mass spectrometry MALDI- -TOF MS (Matrix-Assisted Laser Desorption/Ionisation - Time of Flight Mass Spectrometry). First, it was necessary to prepare a set of model colour layers containing casein and animal glue tempera together with ten inorganic pigments. Consequently, the method of peptide mass fingerprinting was used to obtain mass spectra of the samples. Finally, it was possible to compare and determine the characteristic peptide fragments for both proteinaceous binders and find pigments that most affected the identification of casein and rabbit glue temperas. The obtained values of m/z casein oil tempera and animal glue tempera were used to improve and complete reference database of protein binders that is used to identify protein binders in works of art at the Institute of Chemical Technology in Prague.

Copyright and internet-focused on personal data protection on social networks
Čapek, Martin ; Holcová, Irena (advisor) ; Křesťanová, Veronika (referee)
Herein presented thesis focuses on a very complicated relationship between the Internet and selected law areas. Its aim is to emphasize the influence of information technologies on law; specifically it examines challenges which these technologies present to the copyright law and data protection. The thesis is divided into five chapters. The first and the second chapter with respect to the comprehensiveness of the topic, which they describe, do not have ambitions to analyse the issue in detail; they rather present it in broader and more general context. On the other hand chapter three and four discuss specific data protection and social network issue much deeper. The conclusion of the paper is considered as a certain summary and demonstration of author's thoughts and opinions towards analyzed issue. The first chapter aimed to describe specific environment of the Internet including its origin and development. This chapter also deals with law aspects of the Internet while it presents various considerations that characterise the relationship between law and the Internet, their mutual interaction and challenges they have to face in this environment. The second chapter analyses historical transformations of copyright law and put them in context with growing significance that copyright law undoubtedly has...

Segmentace a odhad hustoty ve stehennim kloubu
Horáček, Jan ; Maršálek, Lukáš (advisor) ; Čapek, Martin (referee)
There are two basic ways of surgical treatment of femoral neck fracture - total endoprosthesis or a special metal screw in the bone. In case of a dense enough bone the screws are preferred. But for a too parse bone, the screw may cut through the femoral head, which results in further surgical operations. We present a novel method for femoral head density measurement, which serves as another hint for the doctor's decision, whether to apply a screw or total endoprosthesis. Our approach is based on semi-automatical femoral head segmentation from CT dataset based on finding optimal path through polar coordinates on axial slices. The cost function is based on a combination of corticallis properties, mostly the directional behavior of 3D gradients and their size in 2D slices, where they form typical "channels". The final volume is computed using filling and morphological algorithms and its properties are further measured. The final implementation was experimentally validated on RTG clinic of Bulovka hospital and allows radiologists to intuitively and accurately estimate the femoral head density in approximately 1 to 3 minutes.

Preparation of N-(2-oxazoline-2-yl-phenyle)barbituic acid
Strnadová, Iveta ; Kotoučová, Hana (advisor) ; Čapek Adamec, Martin (referee)
In my bachelor thesis I dealed with preparation of N-(2-oxazoline-2-ylfenyl)barbituic acid by condensation of N-(2-oxazolin-2-ylfenyl) urea with malonic acid in the presence of acetic acid and acetic anhydride and condensation of the N-substituted urea with diethylmalonate in the presence of sodium ethoxide, too. Original substance for the preparation of N-(2-oxazoline-2-ylfenyl) urea was 2-aminophenyle-2-oxazolin, which was prepared from 2-aminobenzonitrile.

Word problems with topics from chemistry
Poulová, Anežka ; Novotná, Jarmila (advisor) ; Čapek Adamec, Martin (referee)
The thesis is focused on verbal tasks within the subject of chemistry and consists of several parts. The introductory chapter contains a definition of the concept of verbal task, including the basic division of tasks, then the stages of solving the general verbal task and the approach to the solving of verbal tasks with chemical issue is mentioned. The second part summarizes the most common verbal tasks with chemical issue, their theoretical chemical and mathematical basis and offers various ways of how these tasks can be solved. The third part of the paper includes tasks that are an extension of the first part and serves as a sample of interesting examples (also in the terms of mathematical procedures) that are solved in chemistry. The author of the paper tries to show and compare different procedures for solutions and their influence on the efficiency and speed of calculation.
