Lubrication of knee joint replacement
Sadecká, Kateřina ; Horák, Zdeněk (referee) ; Vrbka, Martin (advisor)
The work deals with the lubrication of total knee replacement using fluorescence microscopy method, which allows unique insight into the contact between femoral and tibial component. The aim was to determine the effect of composition of synovial fluid (i.e. albumin, -globulin, hyaluronic acid and phospholipids) on film thickness and protein behaviour in contact, and also to determine changes of contact area during rotation. Since this is the first experimental work dealing with a knee replacement lubrication primarily, only simple rotation and load cycles were applied by the knee simulator. The output of the experiments was fluorescence intensity, which corresponds to dimensionless film thickness, over time. Another important output are the images directly showing the fluorescently labelled proteins in the contact area. The results show, there are fundamental differences in lubrication in different positions of rotation, due to changes of position, shape and behaviour of the contact area. The composition of the lubricant is also essential, since the proteins themselves form a relatively strong lubricating film and their mixture leads to a substantial reduction of film thickness, due to significant formation of clusters. Complex fluid, although it does not form the strongest layer, is able to create a quite continuous film.

Treatment of humeral diaphyseal fractures using Hackethals retrograde elastic nailing - a clinical and experimental verification of this method in contemporary traumatology
Obruba, Petr ; Džupa, Valér (advisor) ; Horák, Zdeněk (referee) ; Paša, Libor (referee)
Hackethal's bundle nailing of diaphyseal humeral fractures was historically reliable and cheap method, used for stabilization of simple humeral shaft fractures. After arrival of solid nails, this technique was successively abandoned, initially in Germany, followed by countries of Central Europe. Several cliniques are at present still using this technique successfully. Goal of this work was to establish, whether the declared stability of this technique is comparable to those of more evolved methods, whether this technique does not cause higher amount of complications, and to describe how the stability of nails bundle depends on number and diameter of used implants. The cost efficiency of different modern osteosynthetic methods used for stabilization of humeral shaft fractures was also analyzed. For verification of determined hypotheses, two clinical and one experimental studies were developed. First clinical study was focused on success rate of osteosynthesis and it's complications. In studied population of 50 patients, 4 of them (8%) developed a non-union, which was in all cases caused by wrong indication or technical error during implantation. Superficial infection was observed once, no deep infection had developed. Nine patients (18%) have healed in rotational or axial malalingement that had no...

The Concept of Marriage Conclusion In the Canon Law Code
Mikulášová, Martina ; Tretera, Jiří Rajmund (advisor) ; Horák, Záboj (referee)
59 THE FORM OF ENTERING INTO MARRIAGE ACCORDING TO THE CODE OF CANON LAW Summary I consider family as one of the most important pillars and foundations of society. A healthy society should be based on family and marriage which is a unique bond between a man and a woman. One way of achieving and enhancing the status of marriage and family in the society is a deeper study of provisions governing marriage. Therefore I take this opportunity to address the institute of marriage viewed upon in terms of Canon law. Canon law could be considered as a part of the European legal culture. Its knowledge is therefore certainly important not only for theologians, but also for lawyers. The conclusion of a marriage in front of the church is also deemed valid and is fully recognized by laws of the Czech Republic. The canonical form is one of the requirements affecting the validity of marriage. Therefore, I find it necessary to give it enough attention. My thesis is divided into four chapters. In the first chapter, I tried to provide the readers with a simple definition of the canonical form of marriage, its historical evolution, and some differences considering the Eastern churches. An enclosed section deals with the current legislation, namely treatment of the issue of canonical form by the Code of Canon Law 1983 and the...

Supportless 3D print by 6-axis robotic arm
Krejčiřík, Petr ; Horák, Zdeněk (referee) ; Škaroupka, David (advisor)
This diploma thesis deals with the solution 3D printing by KUKA robotic arm without realization of supporting structures. The 6-axis KUKA KR 60HA robotic arm allows adjusting 3D printing strategies compared to classical 3D printing concept. The first part of the diploma thesis is about the identification of the current state of knowledge, especially the state of the experimental device for the robotic 3D print. To improve quality of the printed is necessary to modify the printing head and develop the suitable calibration principle. Special printing strategies were designed to rearch the 3D printing overhead volumes without creating support structure. A special alghoritm in the Grasshopper evnironment was developed for generating 3D print trajectory on the body surface. For the quality improvement it is necessary to optimize the process parameters. The final step is experimental 3D printing with the evaluation of surface dimensions, geometric precision and layer coherence in various printing strategies.

Church Subsidies and Their Legal Development in Slovakia and Subcarpathian Ruthenia
Csukás, Adam ; Horák, Záboj (referee)
Church Subsidies and Their Legal Development in Slovakia and Subcarpathian Ruthenia The thesis aims to describe the historical background and legal development of natural church subsidies paid by the members of a parish to their priests in the area of Slovakia and Subcarpathian Ruthenia, with special regard to the late 19th and 20th centuries, up to 1949. Lecticale was a traditional institution of Hungarian customary law, implemented into Czechoslovak law following the declaration of the Czechoslovak Republic in 1918. This legal institution was continuously adapted to the needs of actual legal practice until it was abolished by the communist regime in 1949, a year after the communist coup d'état of February 1948. It was typically adhered to by the Catholic Church and Evangelical Lutheran Church. As the contemporary awareness of lecticale is limited, the author decided to reveal the elements of the researched legal institution one by one, proceeding from very basic information to the most complicated problems of legal practice. Therefore, the beginning of the thesis deals with references to lecticale in numerous Hungarian church law textbooks. The treatise then moves to the 1880s, when the greatest controversies arose regarding the issue. The next part of the thesis deals with the etymology of the word...

The Principles of the Presbyterial-Synodical Ecclesiastical Polity
Csukás, Adam ; Tretera, Jiří Rajmund (advisor) ; Horák, Záboj (referee)
The Principles of Synodical-Presbyterial Church Government This work reflects the principles of the synodical-presbyterial church government, which are referred to in the church constitutions of the Evangelical Church of Czech Brethren and the Reformed Christian Church in Slovakia. The author draws attention to the importance of the principles of church polity in ecclesial life, pointing to their occasional inadequate reflection. In this context, the author points out the introduction of the Führerprinzip in the German Evangelical Church in the 1930s. In addition, he highlights examples of churches that have been able to clearly formulate the principles of church polity, and some of them have even incorporated them into their church law. The author goes on to clarify the basic terminology used in his work, focusing on the naming of Protestant churches in different languages. He deals with the division of churches into families according to the categorization used by the World Council of Churches, paying special attention to the family of United and Uniting churches. He describes five types of these churches, and considering the need to introduce another, a sixth type of United and Uniting churches. Next, he deals with the basic characteristics of Reformed, Presbyterian and Evangelical Lutheran churches. The...

The US Supreme Court, its, formation and first key decisions
Červinková, Zuzana ; Seltenreich, Radim (advisor) ; Horák, Záboj (referee)
These days, the Supreme Court of the United States represents a very important and irreplaceable role in its home land: protection of constitutionality, explanation of federal laws, as well as appellate court of last resort within the framework of American courts. Today there is no doubt about its jurisdiction, but there were doubts. In the beginning of its existence no one was sure if the Court could overcome the initial obstacles which were in the way. This diploma thesis deals with the initial existence of the Supreme Court of the United States, its role within the framework of the US federal power system, and its progressive integration as equal with the legislative branch and executive power - The United States Congress and the President, respectively. The main objective of this thesis is to introduce the federal judiciary of the United States, show its differences from the continental system, and accentuate the importance of precedents. First, I focus on the history of the United States; colonization by British citizens, the American War for Independence, The Declaration of Independence, and the formation of American statehood in the 1780s, which resulted in the acceptance of one of the longest- lasting written constitutions in the world. After the historical excurse, the thesis focuses on...
