Methods of study of porosity of granitic rocks in relation to rock fabric
Votavová, Klára ; Přikryl, Richard (advisor) ; Krutilová, Kateřina (referee)
This bachelor thesis focuses on granitic rocks, which are often used as a building material. Granite are generally rocks with very low porosity, which can be modified (augmented) due to e.g. weathering processes. Increase of porosity is accompanied with deterioration of other physical parameters and decrease of durability. The thesis focuses, after introducing basic petrographical and petrogenetic characteristics of granitic rocks, on the definition of porosity as a physical property, and on various methods used for its determination. Next part of the thesis discusses some case studies which underpin the significance of porosity of granitic rocks by either using combination of several methods, or by using unconventional ones. According to available data, study of porosity and its relationship to rock fabric should be performed by combining several methods of study, encompassing simple petrophysical determination of open and bulk porosities, and microscopic methods allowing for visualisation of pore space - mineral grains relationships. These can be accompanied with less common method of multidirectional ultrasonic sounding allowing for determination of spatial distribution of microcracks present in granitic rocks.

Use of quantifying nursing care for acute psychiatric wards of general hospitals.
ŠIMEČKOVÁ, Marie
The bachelor thesis focuses on special nursing care performed by the nurses in the acute psychiatric ward of a selected general hospital. The theoretical part deals with the care provided in these departments, the most common mental disorders, the ward regime, the competencies of the nurses and the eligibility to carry out the performances and the nursing process that is related to the providing of nursing care. The aims of the thesis and the hypotheses: The aim of the bachelor thesis was to inventory special nursing performances, determine their average time demands and determine the duration of total nursing care in selected groups of patients. We have set three aims, one research question and two hypotheses. The research question was established to determine the special nursing care performances that are carried out the most frequently at the given department. The established hypotheses assumed different time requirements for selected nursing performances and nursing care in selected patient groups. Methodology: A quantitative survey was used in the research part using the Method for determining the number and quantification of the attending staff in the standard treatment units for adults from Pochylá and Pochylý (2008). Structured observation using a record sheet was employed. Research file: General nurses and nurses with specialized competencies working at the psychiatric ward of the general hospital. Results: Twenty special nursing performances were inventoried, of which 261 frequencies were recorded. The highest frequency was the submission of per os medication. Hypotheses have been verified. Average time values for individual nursing activities of special nursing care differ. The longest duration was established in patients with schizophrenia and the shortest duration was found in patients with depression. Practical Use: The results of a research survey can be used to update a methodology consistent with current trends.

The use of quantification of nursing care in psychiatric hospitals
STUCHLÍKOVÁ, Jindřiška
Theme of the bachelor thesis is a utilization of quantification of nursing care in psychiatric hospitals. Psychiatry provides a treatment to persons with mental disorder. In most cases there is nobody to help the patient with his problems. So he searches some specialiste, in this case a psychologist or a psychiatrist. The doctor determines hospitalization of the sick man if the patient is not able to visit an ambulant treatment. For these patients there is performed a basic and a special nursing care. The basic nursing care is composed of feeding, hygiene, etc. The special nursing care provides diagnostic, terapeutic and monitoring operations. The thesis has theoretical and scientific parts. The theoretical part deals with discipline of psychiatry, with form and methodes of care, with legislative definition and with education and competences of nurses. The scientific research was realized by methode of quantification of nursing care by Pochylá and Pochylý (2008), it is a qualitative and quantitative methode. The first part deals with collecting of datas and subsequent recording datas to a record sheet. Next step was to determine activities of special nursing care. There were determined averages and standard deviations for operations thereby we gained average periods of all operations. The purpose of the thesis was to determine average time difficulty of all operations and to determine time values of nursing care of selected groups of patients. The research finds that the nursing care is the most used operation for sick men. Nursing care changes in patients according to the current state of health. Other specifics of nursing care include monitoring patients who may endanger themselves or their surroundings. The most often performed operation in psychiatric hospital in medication is per os. We chose 3 goals for the job. The first objective was to inventory special nursing care in psychiatric hospitals. Another objective is to determine the average time values for individual nursing activities of special nursing care in a psychiatric hospital. The final goal was to determine the time values of special nursing care in selected patient groups. Based on the first goal, a research question has been identified: What is the most common performance in a psychiatric hospital? Based on the second objective, the research question was determined: What are the average time values for individual nursing activities of special nursing care in a psychiatric hospital? Based on the third objective, the hypothesis was chosen: The time values of special nursing care are different for selected patient groups.

Detekce a kvantifikace inhibitorů proteáz v klíštěti \kur{Ixodes ricinus} pomocí monoklonálních protilátek
VANÍČKOVÁ, Martina
Inhibitors of proteases in tick saliva play an important role during tick feeding. Tick saliva contains a wide range of bioactive components which are able to modulate host imunity. Therefore, ticks are able to feed for a long time and transfer tick-borne diseases pathogens. The risk of transfer can be significantly reduced by deactivation of theese protease inhibitors. In this study I made monoclonal antibodies for detection and quantification of two serine protease inhibitors in tick saliva and other tick-body parts.

Methods of study of porosity of granitic rocks in relation to rock fabric
Votavová, Klára ; Přikryl, Richard (advisor) ; Krutilová, Kateřina (referee)
This bachelor thesis focuses on the problem of porosity of granites. The introductory part of the thesis describes granites, their origin, and classification. Specific concern is given to granites as building materials; therefore factors influencing the quality and durability of building stone are mentioned. Porosity of granites can be observed by several different methods. However, none of the methods provides accurate information on present pores from all points of view. From the methods used, mercury porosimentry performed under laboratory conditions seems to be one of the most effective methods. Other effective approaches are microscopic techniques, such as a scanning electron microscopy with energy dispersive spectrometry and/or optical microscopy. Generally, it is suggested to combine several methods to combine information on the volume and distribution of pores with their shape and size.

Quantitative properties of Banach spaces
Krulišová, Hana ; Kalenda, Ondřej (advisor) ; Raja Baño, Matias (referee) ; Hamhalter, Jan (referee)
The present thesis consists of four research papers. Each article deals with quan- tifications of certain properties of Banach spaces. The first paper is devoted to the Grothendieck property. The main result is that the space ∞ enjoys its quan- titative version. The second paper investigates quantifications of the Banach- Saks and the weak Banach-Saks property. The relationship of compact, weakly compact, Banach-Saks, and weak Banach-Saks sets is quantified, as well as some characterizatons of weak Banach-Saks sets. In the third article we discuss possible quantifications of Pelczy'nski's property (V), their characterizations and relations to quantitative versions of other properties of Banach spaces. The last paper is a continuation of the third one. We prove that C∗ -algebras have a quantita- tive version of the property (V), which generalizes one of the results obtained in the previous paper. Moreover, we establish a relationship between quantita- tive versions of the property (V) and the Grothendieck property in dual Banach spaces. 1

Morphology of the Abdominal Aortic Aneurysm
Eberlová, Lada ; Valenta, Jiří (advisor) ; Stingl, Josef (referee) ; Šebesta, Pavel (referee)
Dissertation Abstract Abdominalaortic aneurysm (AAA) is a serious disease. Its prevalence is in the developed countries about 3%. As an aneurysm is considered a dilatation of all layers of a vessel wall over 3 cm. Majority of AAA are small and asymptomatic, and although the risk of rupture increases with the size of aneurysm sack, even the small aneurysms rupture. The rupture mortaliry ranges about 70 %. Surgical treatment is indicated in the asymptomatic patients in diameter of AAA over 5 cm. The average speed of growth of AAA is 0.3 cm per year, e.g. in the early diagnosed patients there is a several years interval for a pharmacolocical influencing of the progression of this disease. Knowledge of pathogenesis is essential for any targeted pharmacological treatment. Our prospective, non-randomised studies are based on the application of the stereological methods for the histopathological assessment of the AAA samples. The acquired data enable the statistical analysis, including the null hypothesis testing. In our study analyzing the histopathology of AAA aortae of 65 patients (65 walls and 55 thrombi) and 6 normal abdominal aortae from the organ donors we assessed the following parameters: the area fractions of collagen and elastin, and the length density of elastin in intima and media, the area...

Effect of resolution recovery on image quality in myocardial perfusion SPECT
Skibová, Daniela ; Šámal, Martin (advisor) ; Judas, Libor (referee) ; Zimák, Jaroslav (referee)
Objectives: Resolution recovery algorithms (IR-RR) were recently proposed as tools to improve quality of SPECT images through better resolution. The aim of the presented study was to investigate the effect of IR-RR on myocardial perfusion SPECT studies. Methods: Phantom and clinical studies were performed using SPECT-CT Infinia/Hawkeye (GE Healthcare). NEMA triple line phantom was scanned according to NEMA procedures. Cold sphere and cardiac phantom were scanned under clinical conditions (900 -angled detectors, 60 views and circular orbit) and reconstructed via IR-RR (Evolution for Cardiac, GE, 12 iterations and 10 subsets), OSEM (ordered subset expectation maximization, 2 iterations and 10 subsets) and FBP (filtered back projection). IR-RR and OSEM reconstructions were used with/without attenuation and scatter correction (ACSC). The effect of post-reconstruction filtering was evaluated. In clinical studies two data-sets were used (half-time and full-time). Conventional scan using full-time (20 sec per stress projection and 25 sec per rest projection) was reconstructed via FBP and IR-RR; half-time scan (10 sec stress, 12 sec rest studies) was reconstructed via IR-RR. End-diastolic volume (EDV), end-systolic volume (ESV) and left ventricular ejection fraction (EF) were calculated using two software...

Past Participle in Contemporary Spanish
Mrkvová, Jana ; Čermák, Petr (advisor) ; Zavadil, Bohumil (referee)
v anglickém jazyce: The topic of this dissertation is the past participle and its use in the contemporary Spanish language system. The character of the thesis is both theoretical and empirical. The theoretical part delineates the issue of the Spanish past participle in the context of non-finite verbs and explores the general matters of the past participle connected with its morphological and syntactic- semantical features. The empirical part consists of two case studies of selected past participle constructions, dar por + past participle a una vez + past participle, based on language research within the parallel corpus InterCorp and single language corpus CREA. The aim of the research is to identify the particular past participles forming the core of the above-mentioned constructions and, by way of contrastive analysis, describe the possibilities of expressing these constructions in the Czech language. The individual findings are quantified and documented by examples.
