SECONDARY PREVENTION PRACTICE AND PROGNOSIS OF PATIENTS AFTER ISCHEMIC STROKE JIŘÍ VANĚK, M.D. 2nd Department of Internal Medicine, Medical Faculty of Charles University and University Hospital, Pilsen, Czech Republic ABSTRACT It is evident that cerebrovascular disease including ischemic stroke belongs to the most common cause of disability or death in the world population. Secondary prevention in poststroke patiens can lead to reduce risk of recurrence or extend lifetime like in coronary heart disease (CHD). The principles of secondary prevention are well implemented in population with CHD, but the situation in poststroke patients is quite different. The assesment of secondary prevention in poststroke patiens and a comparison with patient with CHD was selected for a goal of this study. The study population consisted of Czech patients examined in the framework of well-defined surveys in patients after their first ischemic stroke. Patients represented pooled Czech samples of the project EUROASPIRE Stroke Modul or Stroke Survey in 2007 and in 2013. Better results in acute care were detected. Admissions in stroke unit in 2013 were realized more often than 2007 and fibrinolisis was aplicated more frequently too. On the contrary, arterial hypertension wasn't controlled better than the general population of...
Tooth extractions in patients with coagulation disorder
Houba, Robert ; Houbová, Helena (advisor) ; Vaněk, Jiří (referee) ; Stanko, Peter (referee)
The study deals with the question of minor oral surgery procedures, dental extractions especially, in patients suffering from haemocoagulation disorder. The aim of this study was 1) the clinical attestation of the risk of bleeding that may follow the dental extraction in patients with non-interrupted oral administration of drugs with the anticoagulant and antiplatelet effects and 2) suggestion of the schedules of surgical procedures suitable for this kind of patients and for the realization in the standard dental office. The opening theoretical part analyses the principle of haemocoagulation, the surway of individual inherited and acquired bleeding disorders and the main principles of treatment of bleeding patients in dental offices with the emphasis on the local security of the surgical wound. In the proper study we present the observation and evaluation of bleeding complications after the standard dental extractions in 3 groups of persons (age range, 19 to 93 years). In all patients, one or more extractions were performed. 99 patients were treated with oral anticoagulant therapy without any interruption and underwent 199 extractions. 149 patients, treated with antiplatelet therapy (acetylsalicylic acid) without interruption, underwent 347 extractions. 160 healthy subjects with 316 extractions served as a...

Firts, the object itself is descirbed and it’s energy consumption is detected and the suitable type of FVE is selected. The conclusion of the work consists the financial balance and economic return.
SELECTIVE EMITOR FOR THERMOPHOTOVOLTAIC SYSTEMS
Šimonová, Lucie ; Hrzina,, Pavel (referee) ; Šály,, Vladimír (referee) ; Vaněk, Jiří (advisor)
The work is focused on research and development of a suitable method for creating a selective emitter for the visible and near infrared region so that they are able to work optimally together with silicon photovoltaic cells in a thermophotovoltaic system. The aim of the work was to develop a new method of creating very fine structures outside the current standard, which will increase the emissivity of the base material to meet the needs of a selective emitter for the VID and NIR region. The methods available to us for the creation of structures were chosen, from which we eliminated all unsuitable ones and we introduced the optimal procedure and parameters for their creation for the selected method. In this work, we focused on both ceramic and metallic materials, whose heat resistance and selective properties are key to this work. Part of the development of the emitter structures was also the need for pretreatment of the substrate itself, where great emphasis was placed on the purity of materials and surface roughness. Since ceramic materials cannot achieve a surface roughness so low that the desired structures can be formed, these materials have been purposefully used primarily for the purpose of combining the base material with thin layers of other high temperature material. Their compatibility and suitability were verified in terms of adhesion and subsequent heat resistance. The main material for the formation of fine structures was purposefully chosen tungsten, for which we verified the influence of the formed structure on the emissivity as well as the thermal stability during long-term exposure to high temperatures. The work thus represents not only a new method of creating very fine structures, which are not normally formed in such subtlety, but also opens the way to new possibilities of combining more materials to achieve the required selectivity of the thermophotovoltaic emitter.

Use of a photovoltaic power plant for an integrated rescue system
Jelínek, Richard ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The work deals with the issue of using a mobile photovoltaic power plants in the interventions of the units of the integrated rescue system. It analyzes the theory of solar energy and its conversion into electrical energy and then analyzes the individual elements of the photovoltaic power plant. It tell us what type of pump is used in interventions and what and which type of power plants is used in. He then deals with his own design of a power plant, which serves as an alternative energy source, for internal combustion engines.

The bachelor's thesis deals with the introduction to the components of a photovoltaic system and the creation of a specific photovoltaic system installed in a family house located north of Olomouc. The system is designed to meet the requirements of a family of four. Based on simulations and current market prices, the profitability of the entire system is evaluated. The financial return of the project and the possibility of a subsidy from the state are also considered. In addition, the future possibility of purchasing an electric car is included and the potential impact on the flow of energy within the internal power grid is simulated.
Design of a photovoltaic power plant for a family house near Jihlava
Dvořák, Vít ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
This diploma thesis deals with the design of a photovoltaic solar power station for a specific family house in the Jihlava region. The aim of the work was to get acquainted with technologies about the production of solar systems, evaluate the market in the Czech Republic and create a design of photovoltaic solar power station. Three designs of power stations were created with the help of the PV * SOL design system. Each design uses different photovoltaic cell technology. The result of each power station design is a complete finished project, which is based on many factors such as the efficiency of the entire system in a certain location, financial analysis, return on investment and more. In addition, these projects meet the conditions for the preparation of the subsidy program Nová zelená úsporám. At the end of the work, all three designed power stations are evaluated and with the help of multicriteria analysis, the best and most advantageous power station design for the given locality is determined. In the end, the idea of further development of the project is presented.
