Výpadky proudu v Nemocnici Jihlava. / The power outages in the hospital Jihlava.

CHVÁTALOVÁ, Jana January 2014 (has links)
Health - without a doubt - is one of the most precious gifts and it is one of the most important values for each of us. The human body fascinates humanity throughout its existence. Since the beginning of the first medicinal extracts to modern robotic surgery, people strive for the same - to prevent diseases, full recovery of health or to bring closer this state. The whole developed society is interested in our good health. It is necessary to ensure the functional part of the infrastructure, so called critical infrastructure. Unplanned power blackout can have disastrous consequences not only for the patients. Plenty of electrical energy is required for the functioning of hospital. The electrical network in the hospital is very fragile. It is necessary to have alternative sources of electricity in hospital. For each hospital is a priority ability to reliably protect the power grid to avoid damaging consequences of its lack. This thesis entitled "Power blackout in Jihlava hospital" focuses on the question of emergency unscheduled power blackout Hospital Jihlava, also explains the basic concepts related to this topic and describes the functioning of the hospital equipment. The theoretical part consists of several chapters which provide basic information about electricity, the electricity grid, power plants, transmission and distribution systems, principles and functioning of the hospital. There is clear description of the Maslow's pyramid of human needs, in this part is also explanation of the term "blackout" and the incidence of several serious blackouts of electricity in the Czech Republic and worldwide, experience with them and their impact on human society. The practical part is the basic characteristic of Hospital Jihlava, location of alternative sources - diesel power generators, a description of the various sources of electric power, their function and principle of functioning of Hospital Jihlava. The whole research theoretically examined the readiness Hospital Jihlava to power blackout. The basic method of investigation was to collect data that was obtained through a guided interview with the responsible employees, their answers were transcribed into text and then were analyzed risks identified by the method KARS, in order to investigate the size of the impact of the crisis situation on patients. It is assumed that it is sufficiently adequate protection against failure of the power system, that could at power interruptions, endanger patients, staff, expensive diagnostic and surgical instruments actually overall functioning of this important institution. Based on the investigation was identified the need to inform the public, staff, patients and top management. Technicians may well ensure the functioning of important machinery and equipment. Equally important is understanding of this issue by medical staff to be well versed in an emergency situation quickly. The behavior and conduct of staff could help manage the situation without major problems and reduce imminent risk of impact on patiens and expensive instrumentation to a minimum. Also for this purpose could serve the results of this work. The aim of the thesis was to investigate the effects of a power blackout at the Hospital Jihlava on patients and suggest possible measures. The results of the survey show that a sudden power outage Hospital Jihlava presents a serious threat to its functionality, for this reason, in the final part of my thesis are presented the final recommendations, which can not only reduce the risk of impact on patients.

Temperace a chlazení vstřikovacího nástroje

MACHO, Michal January 2018 (has links)
This diploma thesis deals with the design of injection molds, especially it is focused on their temperance and cooling. The aim is to design a beneficial technological process for tempering and cooling the injection mold for critically exposed sites. In the theoretical part I focused on a comprehensive outline of the issue of injection molding and the possibility of tempering and cooling circuits. In the practical part the specified injection was modeled and an injection mold was designed for its implementation. The construction was carried out in the Siemens NX program and the simulation analysis was done in Cadmould 3D - F and Aeroflow software. For the POM material the total shrinkage and warpage of 1.674 [mm] and the flatness of the hem of 0.403 [mm] at a total optimum mold temperature of 80 [°C.] were achieved. For PA material were total shrinkage and warpage 1,745 [mm] and flatness of hem 1,649 [mm]. I researched that the maximum mold temperature at POM injection is 94.862 [° C] and the end temperature at the end of the cycle is 87.259 [°C] at a critical point. The main finding is the possibility to affect the overall shrinkage and warpage along with the flatness of the hem by varying the temperature of the cooling circuits. Based on the detected data, the active cooling circuit is more suitable for installation than the passive cooling element. The results of this work enable shortening of the technological cycle time of the injection mold and selecting of a suitable cooling solution for exposed injection sites.

Critical Theory and Dialectics of Contemporary Economics / Critical Theory and Dialectics of Contemporary Economics

Maialeh, Robin January 2017 (has links)
The subject of this dissertation thesis is a confrontation of contemporary economic thought with critical theory. Based on the holistic critique of the production process, the author deals with elementary principles of wealth creation and allocation, mirroring themselves in the issue of economic inequality. An applied transdisciplinary approach leads to dialectical understanding of market mechanism which accentuates an antagonistic character of its actors´ aims and reveals its non-empirical causalities. These abstract connections then become a viable explanatory complement to already advanced empirical apparatus of economic inequality. The goal of the thesis is to formulate an economic model that takes into consideration both empirical findings of contemporary studies on economic inequality and reflection of the critical theory. The value added lies in the fact that the economic model presents an interaction of economic agents and through probabilistic drive towards deepening economic inequalities exposes market mechanism as the diverging factor of social reproduction. Further, the model shows that Pareto-optimization, a frequently used analytically-normative tool of contemporary economics, principally does not suffice in grasping market-based inequalities. The contribution of the thesis is researching particular economic phenomena from the unique perspective which has not been yet fully accomplished in the context of modern economics.

Kořínek, Tomislav January 2014 (has links)
The goal of the dissertation is to find an effective form of optimization of the progress developer projects using IT technology in the point of view of a project manager. The theoretical part of the dissertation is dedicated to the project management's theory and clarification all used terms. After the theoretical part follows the description of progress of a standard developer project of building a department store. The fourth part is dedicated to the freely available software for a project management in perspective of applicability for a project control, a documentation process and sharing comments to be used inside a company in relation to the other external companies. Then follows a description of the concrete developer project in help of the management theory contained in the second part including activities definition, their logical sequence and competence math. Within the seventh part the first is identified a critical path in using CPM method (Critical Path Method) and then there are described the critical parts of the project and a description of solving the optimization of the project management, which provides a selected software product. At the end of the seventh part is appraised how successfully the critical parts of the project were optimized and increased the efficiency of the work of the project team.

Studium vývoje mikrostruktury pokročilých keramických materiálů ve druhé fázi slinování / Study of microstructure evolution during intermediate stage of sintering of advanced ceramic materials

Jemelka, Marek January 2019 (has links)
Hlavním cílem této diplomové práce byl popis závislosti kritické hustoty (tj. hustota, při které se tubulární póry zcela přemění na póry izolované a uzavřené) a průměrné velikosti zrn při této hustotě na rozdílných rychlostech ohřevu během druhého stádia slinovacího procesu. Dosažené výsledky jsou velice důležité, např. pro produkci transparentních balistických pancířů, vysoce výkonných řezných nástrojů či kostních a kloubních implantátů, jelikož poskytují informace pro výběr nejvhodnější slinovací metody, jejímž výsledkem jsou vzorky v předslinutém stavu s minimální velikostí zrn pro následnou metodu izostatického lisování za tepla (post –HIP). Bylo zjištěno, že kritická hustota všech studovaných oxidových materiálů (Al2O3, tetragonální ZrO2 a kubické ZrO2) není významně závislá na rychlosti ohřevu v rozmezí od 2°C/min do 200°C/min a průměrné hodnoty kritických hustot jsou 96.3 %; 92,4 % a 93,0 % pro Al2O3, t- ZrO2 a c-ZrO2. Výsledky z dosavadní literatury prokázali, že kritická hustota není taktéž závislá na mikrostruktuře keramického polotovaru, a tedy je možné usuzovat, že kritická hustota je materiálovou konstantou závislou na dihedrálním úhlu materiálu. Slinovací trajektorie (tj. závislost průměrné velikosti zrn na relativní hustotě) byly vyhodnoceny jak pro všechny tři způsoby slinování lišící se rychlostí ohřevu (2, 10 a 200 °C/min s dobou výdrže 5 min), tak pro takzvaný způsob slinování- long-dwell (nízké slinovací teploty s dobou výdrže 5 – 10 h). Výsledky nepotvrdily, že by některá z alternativních metod slinování vedla ke snížení průměrné velikosti zrn při kritické hustotě materiálu, a tudíž v současnosti nejvyužívanější metoda pro přípravu materiálů v předslinutém stavu, tzv. metoda konvenčního slinování (rychlost ohřevu 10 °C/min, doba výdrže 5 min), zůstává i nadále vhodnou metodou pro přípravu vzorků s optimální mikrostrukturou pro následný post-HIP proces.
