Vibration of faulty bearing depending on the load
Slaninová, Barbora ; Marcián, Petr (referee) ; Krejsa, Jiří (advisor)
The subject of the presented bachelor thesis is an analysis of a bearing vibration during its failure on inner race with varying load. The work aims to create a model simulating the time course of vibrations in the event of a bearing failure depending on the load and speed of the bearing. The work compares the frequency and time model of the rolling bearing error spectrum. A model of bearing error frequencies was also created, which is supplemented by a force action in the next step. To parameterize the model, data were experimentally measured on a bearing that takes on three possible states. The first bearing has a defect on inner race measuring 0.25 mm, the second bearing 0.5 mm and the third is free of defects. The measurement takes place on a test bed in 135 repetitions. Inventor is used to design the bearing with defect. The measured data are processed and visualized with MATLAB. The measured values show that the rate of vibration is not only dependent on the load and speed, but also the size of the defect.

Saint Petersburg in works of A. S. Pushkin and F. M. Dostoevsky
Slaninová, Barbora ; Hříbková, Radka (advisor) ; Hlaváček, Antonín (referee)
The Bachelor Thesis deals with the image of a city in the literature. Specifically, it analyses the conception of Saint Petersburg in a narrative poem The Bronze Horseman written by Alexander Sergeyevich Pushkin and a novel Crime and Punishment by Fyodor Mikhailovich Dostoyevsky. The thesis is divided into two parts - the theoretical and practical ones. The theoretical section focuses on the topic of urbanism in the literature in general. It concerns with the main key motifs, space-time continuum and general character types. Then the brief history of Saint Petersburg with the special concentration on the 19th century is mentioned. In the practical section the analysis of both literary works is accomplished. On its base these two pieces of work are compared finally. The goal of the thesis was to find some facts these two literary works, in which portrait of Saint Petersburg is depicted, have in common and on the other hand to examine some differing points. It turned out, that The Bronze Horseman and Crime and Punishment, works so different for the cursory check, have a lot of facts in common.

Airway management from the perspective of nurses in intensive care
SLANINOVÁ, Barbora
This bachelor work deals with the possibilities of establishing an airway that can perform nurses for intensive care. Breathing is one of the basic and very important life functions necessary for life. In today's advanced medicine is a wide range of opportunities to ensure the airways, or at least encouraged to perform proper function. Securing the airway is a very important part of the pre-hospital emergency care, but also on the wards in the hospital. The theoretical part of my bachelor is engaged a complex provision of the respirátory tract. The first section deals with the short description of the anatomy and physiology of the respiratory breathing. In other chapters describe airway. The following chapters were directly aimed at ensuring the airway, which were distributed to provide the tools, equipment and without indications for collateral. U airway management devices without describing the revision of the oral cavity, head bent backward and triple maneuver, shot in the back and the Heimlich maneuver. The practical part was focused on determining whether the sisters were higher competence in the provision of respiratory and how intensive care nurses provide their throughput. The research was conducted using quantitative research using an anonymous questionnaire at the hospital in České Budějovice a.s. and in the sand. The questionnaire able be completed only by workers who have graduated from specialty anesthesia resuscitation and intensive care. The questionnaire was printed and included 20 questions. Each question was displayed in a graph. The total number of questionnaires that were distributed, 100, 82 of them returned, but only 61 were fully completed and could be used. Research suggests that nurses who studied ARIP received enough informatik and practical experience during their studies. Specializing mostly work on anestesiology and resuscitation wards and intensive care units. At your workplace have aids, such as laryngeal mask airways and endotracheal tube. The vast majority of respondents have difficulty securing and aspirations in securing the airway. Sisters during their practice provide respiratory laryngeal mask and Combitubus, countless assisted by endotracheal intubation, but its remit would not want to have this power, because of its difficulty. Finally, it is important to note that to achieve the set objectives, where it was found that nurses stand to increase their competence, but only with some performance and throughput. Respiratory ensured by the air ducts and laryngeal masks.
