VYUŽITÍ ALTERNATIVNÍCH TESTŮ BIOTOXICITY PRO STANOVENÍ NEBEZPEČNOSTI STÁVAJÍCÍCH A/NEBO POTENCIÁLNÍCH POLUTANTŮ / UTILIZATION OF ALTERNATIVE TESTS OF BIOTOXICITY FOR DETERMINATION INADVISABILITY OF EXISTING AND/OR POTENTIONAL POLUTANTSVašulková, Lucie January 2008 (has links)
This thesis is focused on attestation of ecotoxicity of octachlorstyrene (OCS), persistent organic pollutant (POP), by biological tests of toxicity. The toxicity of OCS was determined by using two kinds of alternative tests applied on fresh water organisms. First of them, Thamnotoxkit, is based on observation of mobility, immobilization or even killing of crustacean Thamnocephalus platyurus. The second one, Daphnotoxkit, applies crustacean Daphnia magna. For purposes of comparison, a standard test of toxicity – so called test of root growth inhibition of Sinapis alba and two fytotests – test of growth inhibition of Lemna minor and test of root growth inhibition of Allium cepa were performed as well.

Výpočet standartních termodynamických funkcí jednoduchých sloučenin v podmínkách termálního plazmatu / Calculation of Standard Thermodynamic Functions of Simple Compounds under Thermal Plasma ConditionsŽivný, Oldřich January 2011 (has links)
The substance of present work is to provide standard thermodynamic functions (STF) of small size molecules for the calculation of the composition and thermodynamic properties of low-temperature plasma, and also method for such a calculation applying obtained STF under non-ideal plasma conditions. With a view to further application in modelling the phenomena in thermal plasma the range of pressures is limited to the region from 0.01 bar to 100 bar, and that of temperature to 298.15–50 kK. To obtain STF the method of partition function resulting from statistical mechanics was proposed. State of art in the given scientific area and theoretical basis of the statistical mechanics required for establishing of the proposed method together with discussion of partition function divergence problem have been reviewed. For the calculation of STF of diatomic molecules the method of direct summation has been employed, whereas, as for the larger size molecules, the rigid rotor and harmonic oscillator model have been generally adopted. The spectral data required for the calculations have been taken from literature, or, in selected cases, these have been computed by quantum chemistry ab initio techniques. The resulting STF have been included into already existing database system of thermodynamic properties and those can serve as input data for subsequent thermodynamic calculations. A general method has been worked out for the purpose of the computation of thermodynamic properties and composition of non-ideal homogenous plasma system in thermodynamic equilibrium. The method is based on minimizing total Gibbs energy to compute at constant pressure or Helmholtz energy to compute at constant volume. The computation algorithm was implemented into computer program and subsequently applied to the computation of the composition and thermodynamic properties of SF6 dissociation and ionization products using obtained STF.

Efektivní interakce Euler-Heisenbergova typu v modelech kvantové teorie pole / Effective interactions of the Euler-Heisenberg type in models of quantum field theoryPřeučil, Filip January 2014 (has links)
In the present thesis we study light-light scattering, which is a nonlinear effect occurring in quantum electrodynamics. The goal of this thesis is to study the low-energy effective theory (Lagrangians of Euler-Heisenberg type). The first part of the work is devoted to the derivation of the effective Lagrangian in spinor, scalar and vector QED using the amplitude matching of one-loop diagrams. The calculation for the case of vector QED is performed using the unitary gauge, which probably has not been done yet so far by other authors. In the second part, the effective Lagrangian for spinor QED is derived using functional methods. The essential point of the derivation is to calculate the determinant of the Dirac operator in constant background electromagnetic field. Powered by TCPDF (www.tcpdf.org)

Míra stresové zátěže sester na standardních odděleních a jednotkách intenzivní péče. / The rate of stress load on standard nursing wards and intensiv care units.Brzicová, Věra January 2013 (has links)
This thesis deals with the stress, strain and stress level of stress. It examines what more burdens on JIPu sisters and what the standard department, what are the specifics of their work. Compares the work load and nursing department and the standard JIPu. It looks at how the situation affects of stress nurses. It outlines the causes and manifestations of stress effects on the human organism. He is also the burnout that often occurs among workers in the helping professions. The thesis is focused on the shift operation (especially on night shift), relationships at work (sister-sister, sister-doctor), the aggressive behavior of patients, or the lack of sufficient time for patient care. Research method is a questionnaire distributed to the nurses and the internal standard surgical wards and ICU. The evaluation questions of the questionnaire confirms or overthrows the hypothesis that I set at the beginning of research. The hypotheses were confirmed hypotheses 2 and 5 of the hypothesis was not confirmed. It was confirmed that the exchange operation and overload nurses, patient aggression, care of confused patients and bad interpersonal relations a high burden on medical personnel and contributes significantly to the stress load of nurses. In conclusion, I mention that a large role in preventing and...

Postavení a role normové autority v internetových fórech. Analýza korektur na základě Teorie jazykového managementu. / To the Position and Role of the Normative Authority in the Internet Forums. An Analysis of the Corrections in the Context of the Language Management Theory.Šimčíková, Lucie January 2013 (has links)
My thesis deals with the status of German language standard and is based on research in the internet discussion sites (internet forums), that deal with the topic of language. The internet forums that I've chosen offer help in learning a foreign language, in our case German. The help is provided either by proofreading or by answering the specific questions. This thesis is based on Ulrich Ammon's model of four social forces and the theory of language management. Next to the instances, which according to Ammon determine the standard, I included the participants of discussion, who decide what is standard too and thereby affect those for whom isn't German the native language. The analysis will be carried out on the basis of the proofreading of model texts. With the help of the language management theory I will discuss with the proofreader in the comments their selected (or not selected) option. The aim of my work is to observe the behavior of normative authority in relation to the codified norm, whether they know and follow it. Furthermore, I am interested in the social background and language abilities of the participants, which I'll find out by using the questionnaires.

Systémy hodnocení soutěží v tanečním sportu z pohledu porotců / Judging systems of competitions in dancesport from judges point of viewŠťastná, Zuzana January 2019 (has links)
Title: Judging systems of competitions in dance sport from judges point of view Objectives: The main goal of the thesis is to introduce the absolute judging system used on a dances sport competitions 3.0 to a wider public, and to describe differences between absolute judging systems 2.0, 2.1 and 3.0. Next goal is to map opinions, knowledge and attitudes of the TOP judges of the CDSF towards the judging systems of the dance sport. Methods: To obtain the necessary data for the elaboration of the thesis was used a method of electronic questionnaires. For the elaboration of a theoretical part of the thesis were used primary sources, professional literature and experts' own materials. Result: The thesis maps used systems of dance sport in the Czech Republic and abroad and their main progress towards objective and measurable judging. Based on survey, the questionnaire reveals the knowledge, opinions and attitudes of the Czech TOP judges towards System 3.0. In fact, the thesis is a breakthrough, because even though the absolute judging system 3.0 is already used in practice, there is still no Czech written documentation of its work or usage. Keywords: Dance sport, Latin, Ballroom, Dance, Judges, Judging systems, Sport, The questionnaire

The purpose of this thesis is to examine the experience of nurses with burnout syndrome and its prevention. In order to this, I have been examining a number of nurses who have experienced burnout syndrome, the level of intensity they experienced and the nurses' opinion on the prevention of this psychical state. The theoretical part will focus on the nurses' job description and psychological stresses related to their duties. Furthermore I will focus on burnout syndrome - its risk factors, causes, stages and prevention. I will inform as well about daily course and operations at the Intensive Care Unit and the standard inpatient department. The empirical part focuses on comparing the level of burnout syndrome of nurses working in the Intensive Care Unit versus those working in the standard inpatient department. Furthermore I am examining the experience of nurses with the burnout syndrome and its prevention. I will use a questionnaire as the research method.

Modeling of natural catastrophes / Modelování přírodních katastrofZuzák, Jaroslav January 2011 (has links)
This thesis introduces various approaches to natural catastrophe risk assessment in (re)insurance environment. Most emphasis and further elaboration is put on probabilistic models in comparison to the standard model as proposed by Solvency II. The outcomes of natural catastrophe modeling play an important role in the design of proper actuarial models related to catastrophe risk. More specifically it is shown that they can be entirely understood in a wider actuarial context, namely risk theory. Within the Solvency II framework, probabilistic model outcomes are translated by means of the proposed decomposition methodology putting them into a similar language of the standard formula in order to create the ability to compare different results implied by either probabilistic model or standard formula. This enables both comparison of the implied dependence structure of probabilistic model to standardized correlations assumed in Solvency II, and scenario year loss factors of Solvency II to implied damage factors of probabilistic models in defined cresta zones. The introduced decomposition methodology is illustrated by flood and windstorm model outcomes calculated on exposure data of Czech insurance companies and compared to the respective standard formula parameters and outcomes. Finally, other applications of the proposed decomposition methodology are introduced, such as measurement of diversification effect or blending of different results calculated by different models or even approaches to natural catastrophe risk assessment.
