Burners for high-temperature industrial applications
Naď, Martin ; Hájek, Zdeněk (referee) ; Bělohradský, Petr (advisor)
The main purpose of the bachelor thesis is the discussion of different types of burners and their components. Emphasis is placed mainly on the combustion process with oxygen content more than 21 % in the combustion air, the so called oxygen-enhanced combustion (OEC). The thesis describes characteristic features, possibilities and appropriateness of its use. Since in handling of oxygen there is a level of risk of injury, the thesis also assesses the safety and risks associated therewith. As the combustion process in terms of OEC is significantly different from the conditions of combustion with the atmospheric air, the thesis analyses the impact of the content of oxygen in atmospheric air on flue gas temperature and fuel consumption.

Oxygen therapy in newborns of nursing perspective
KADLEČKOVÁ, Zuzana
The thesis concerns the treatment of newborns with oxygen from the nursing perspective. Work has part of theoretical and of research. In the theoretical part I focus on the latest European Resuscitation Council best practices in the administration of oxygen as well as longer-term oxygen according to best practices of the Czech neonatology in inpatient Department. First, particular attention devoted to the reconstruction of the fetoplacental circulation of the newborn with subsequent changes in his lung and blood circulation after birth, because it is an integral part of the knowledge in the treatment of oxygen. The next section is devoted to the principles of the first treatment of the newborn, in particular with regard to the assessment of the postnatal adaptation and the decision to open the oxygen therapy by nurse or midwife assistant. The following are mentioned in the work at the same time valid recommendations for the resuscitation of the newborn, again with an emphasis on the question of the use of oxygen. In the next chapter is summarized the most common neonatal pathology, which requires oxygenotherapy. The following chapter covers ways to feed oxygen to newborns as early in the process of adaptation, so when a stay in the neonatal intensive care unit. There are described the proper techniques of monitoring and summarises the complications of treatment with oxygen in its inadequate application. Research section includes the identification of the knowledge of the nursing staff in the treatment of oxygen for newborns and then system in the education of nursing staff in matters of oxygen therapy. For research were established two objectives. The first objective is to map the knowledge of nursing staff in the principles of application of oxygen for newborns in the neonatal intensive care and resuscitation and in the birthing room. And the aim of the second was to determine what form is tutored by the nursing staff in the area of oxygen for newborns. On the basis of these objectives have been laid down 3 research questions. The first question is: What are the main differences between knowledge and best practice version of the nursing staff in the application of oxygen for a newborn? The second question is: Is the education of nursing staff in the resuscitation of the emphasis is on the practical implementation and on the systematic recurrence? And the third question is: How does the education staff in the principles of oxygen therapy beyond resuscitation? For research inquiries, he was elected qualitative research. For data collection have been used individual interviews with 5 children's nurses, who work in a specialized neonatologickém work in the field of neonatal intensive care units and in the field of bithings rooms of the Hospital Department in České Budějovice a.s. The Interviews were subsequently rewritten into a Bachelor's thesis and at the conclusion of the results of a detailed table was created, where results are presented. Of the investigation can be concluded that nursing staff have sufficient knowledges in the field of oxygen therapy in newborns and nursing and best practices in the application of oxygen. As regards education, which relates to the resuscitation of newborns is done regularly, once a year in the Department The results of the work could be used to identify deficiencies in training in the field of application of oxygen in resuscitation with the aim of directing the education of personnel in this area.

Study of photosynthetic response of green algae on presence of selected heavy metals
NOVÁK, Jan
With the world population growth, more and more agricultural areas fall into regions affected by waste products. Therefore it is important to determine their impact on environment toxicity. The aim of this thesis is to evaluate the effect of selected ions of heavy metals (CoSO4, CuSO4, CdSO4, ZnSO4 and K2Cr2O7) on the process of photosynthesis in a selected green algae species (Scenedesmus quadricauda) by means of monitoring of dynamics of oxygen release into solution of nutrient medium. The experiments with individual compounds proceeded by pH 7, temperature 25°C and light 450 ?mol m-2 s-1. Algareact device developed by the company BVT Technologies was used for measuring. Comparison with growth curves Scenedesmus quadricauda by different pH was used for the validation of the method. The method of the measurement of dissolved oxygen in medium is suitable for the measurement of immediate impact of chemical compounds on photosynthetic activity of examined organism. The method is restricted by the fluidity of measured solution. The lowest quantity of oxygen disolved inmedium was measured by CdSO4 in concentration 0,1 M.

Oxygen application in nursing care.
ČÁPOVÁ, Michaela
Oxygen therapy or oxygen treatment belongs among the most important non-pharmacological medical treatments and it is applied in all types of establishments. It is indicated to patients with the lack of oxygen and respectively in the oxygen concentration higher than 21%. The aim of the oxygen treatment is to increase the oxygen concentration in the breathed mixture and consequently in the arterial blood in order to prevent from damaging the important tissues and organs. The nurse applies oxygen always according to the doctor´s prescription, who states the potion, the way of application, the length of application and monitoring. The treatment can be applied at spontaneous ventilation and at artificial pulmonary ventilation namely under normobaric or hyperbaric conditions. The basic presumption for the successful oxygen treatment is sufficient ventilation of the patient. Oxygen can be used from different sources such as pressure cylinders, liquid oxygen and oxygen concentrators. The thesis deals with the issue of oxygen application in the process of nursing care. The thesis is divided into two parts ? theoretical and practical. The theoretical part involves history of oxygen application, physiology and pathology of oxygen in the body, indications and contraindications of oxygen applications. Further it contains specifications of nursing care for the patient who is undergoing the oxygen therapy including possibilities of oxygen application, patient´s monitoring, sources and aids for oxygen application. For the practical ? research part of the thesis the data were found out by means of the method of questioning. I used the technique of the questionnaire which was anonymous and the questions were both closed and semi-closed. The observed team were nurses working in the hospital wards in the Písek Hospital, a.s. and in the Strakonice Hospital, a.s. The aim of the thesis was to map out specifications of nursing care for the patient when oxygen is applied and also to find out nurses knowledge of ways of oxygen application in individual wards. The information collected from nurses working in standard wards with those working in intensive care units was compared. Hypothesis no. 1, that nurses know specifications of nursing care, was proved in the research process. Hypothesis no. 2, that nurses know possible complications (risks) when oxygen is applied, was proved. Hypothesis no. 3, that nurses know ways of oxygen application, was proved, too. The aims of the thesis were fulfilled. Results of the research work were used for making the nursing standard whose aim is safe and proper oxygen application in order to prevent from harming the patient. It can be a source of information and a manual for the hospital nurses who do not use this standard yet.

Level of knowledge of midwives and pediatric nurses for oxygen therapy in neonates and infants
JIRÁKOVÁ, Nikol
Abstract The theoretical part of the thesis focuses on oxygen therapy of mature and premature newborns, particularly as a part of resuscitation. The thesis summarizes general findings about postpartum adaptation of individual groups of newborns and about immediate care provided in the delivery room. The theoretical part also deals with a nursing care of newborns and young babies requiring ventilation support in the hospital neonatology ward. The practical part surveyed both theoretical knowledge and practical skills of pediatric nurses and midwives. The survey used quantitative inquiry and observation. Anonymous questionnaires were distributed to midwives and pediatric nurses working at the gynecology-obstetrics and neonatology wards in the hospitals in České Budějovice (Nemocnice České Budějovice, a. s.) and in Benešov (Nemocnice Rudolfa a Stefanie Benešov, a.s.) The observation was conducted during my practice at the neonatology ward in the hospital in České Budějovice. The thesis had one formulated objective and two related hypotheses. The objective was to determine the level of knowledge of midwives and pediatric nurses about the principles of treatment of newborns and young babies with oxygen. The objective has been met. Hypothesis 1: ?I believe that the level of knowledge of midwives and pediatric nurses about the oxygen treatment of newborns and young babies is sufficient? has been confirmed. Hypothesis 2: ?The nursing team in the delivery room is familiar with the current recommendations for application of oxygen during resuscitation of newborns in the delivery room? has been confirmed. This bachelor degree thesis may serve to future students of midwife profession as a study material and source of information. Moreover, the thesis might be used as an educational material for midwives and pediatric nurses working in delivery rooms and at neonatology in-patient wards.

Intenzita záření a teplota vyhasínajícího stejnosměrného výboje v směsi dusík-kyslík
Krčma, F. ; Mazánková, V. ; Soural, I. ; Šimek, Milan
This contribution focuses on the oxygen influence to the pure nitrogen post-discharge. The DC flowing afterglow in Pyrex tube at discharge current of 150 mA and pressure of 1000 Pa was studied by optical emission spectroscopy at decay times in the range of 3 – 45 ms. Band head intensities of 1st and 2nd positive and 1st negative nitrogen spectral systems were observed as a function of oxygen admixture ( 0-5000 ppm). The nitrogen pink afterglow effect was observed in all cases. Temperature during the afterglow was determined by two different ways. The first one was the direct calculation of the rotational temperature of nitrogen 1st positive 2-0 band using numeric simulation. The second way was the strongly temperature-sensitive ratio of band head intensities originating from 11 and 12 vibrational levels of N2 (B 3g) state because these levels were populated during the afterglow mainly by the atomic nitrogen recombination.
