Nutritional analysis and optimization of breeding of selected species of edible insects under conditions of the Czech Republic with regard to human health
Adámková, Anna ; Kouřimská, Lenka (advisor)
All over the world, the edible insects are considered a highly nutritious food with high protein and fat content. However, the nutritional value of insect is not constant. It can be affected by species, developmental stage, rearing technology or nutrition.
Therefore, this thesis was aimed at obtaining the selected nutritional value of edible insects. Analyses were focused on the determination of the crude protein content, fat content, fatty acid profile and sterols in selected species of edible insects, which can be commonly reared in the Czech Republic. At the same time we also analysed samples of insects reared on the island of Sumatra to evaluate the influence of the climate on the nutritional value. The main aim of the thesis was the determination of optimal breeding conditions, developmental stages and feed rations for obtaining good production of insects with nutritional properties suitable for human nutrition. The analyses showed a high nutritional value of selected insect species, but also confirmed the significant differences in the content of individual nutrients between different species depending on the climate conditions and developmental stage. Comparing the fat and crude protein content in edible insects and other conventional sources of meat it has been found, that the examined insect is similar to beef concerning the fat and crude protein content. The results obtained are the basis for determining the appropriate rearing conditions and developmental stages for obtaining insect with the desired nutritional properties for human nutrition.

The use of biomass ash
Ochecová, Pavla ; Tlustoš, Pavel (advisor) ; Radim, Radim (referee)
One of the most frequently used sources of renewable energy is biomass, mainly wood biomass. Incineration is the most common technology utilizing the energy from biomass to produce heat. A byproduct of these technologies is ash, whose composition depends on the feedstock composition and the incineration technologies. Due to the high content of valuable nutrients in ash, one of the suitable option for ash utilization seems to be application into agricultural or forestry land. Therefore, it is necessary to test response of soils and plants and look for the most suitable combination of soil additive (biomass ash), and plants. Experimental part of PhD thesis was divided into the incubation experiment and the vegetation pot experiments. The incubation experiment: The efficiency of ash addition at two application rates was tested for nutrients enrichment in different soils within period of 56 days. The vegetation pot experiments: The two plants Triticum aestivum L: (three-year experiment) and Lolium perenne L. (one-year experiment) were planted in the 5L pots. Soils were treated with ash or ash combinated by superphoshate and flue gas desulfurization gypsum. For both plants, we evaluated the plant growth, biomass production and content of macro, micro and toxic elements in the biomass and in the soils.

Frequency stabilized semiconductor laser source for high-resolution interferometry
Řeřucha, Šimon ; Hucl, Václav ; Holá, Miroslava ; Čížek, Martin ; Pham, Minh Tuan ; Pravdová, Lenka ; Lazar, Josef ; Číp, Ondřej
We have assembled an experimental iodine stabilized Distributed Bragg Reflector (DBR) diode based laser system lasing at a wavelength that is in a close proximity to the wavelength of a stabilized He-Ne lasers traditionally used for metrological applications (λ=632.9 nm in vacuum). The aim was to verify whether such a system could be used as an alternative to the He-Ne laser while yielding wider optical frequency tuning range, higher output power and high frequency modulation capability. We have measured the basic characteristics of the laser source and then we have compared the performance of the laser system with that of a traditional frequency stabilized He-Ne laser with a series of experimental arrangements similar to those usually found in laser interferometry and displacement metrology applications. The results indicate that DBR diode laser system provides a good laser source for applications in dimensional (nano)metrology since it provides more output power and advanced tunability options than stabilized He-Ne lasers while maintaining fundamental requirements such as the frequency stability, coherence length and also a defined traceability.\n\n

Stiff Systems Analysis
Šátek, Václav ; Dalík, Josef (referee) ; Horová, Ivana (referee) ; Kunovský, Jiří (advisor)
The solving of stiff systems is still a contemporary sophisticated problem. The basic problem is the absence of precise definition of stiff systems. A question is also how to detect the stiffness in a given system of differential equations. Implicit numerical methods are commonly used for solving stiff systems. The stability domains of these methods are relatively large but the order of them is low. The thesis deals with numerical solution of ordinary differential equations, especially numerical calculations using Taylor series methods. The source of stiffness is analyzed and the possibility how to reduce stiffness in systems of ordinary differential equations (ODEs) is introduced. The possibility of detection stiff systems using explicit Taylor series terms is analyzed. The stability domains of explicit and implicit Taylor series are presented. The solutions of stiff systems using implicit Taylor series method are presented in many examples. The multiple arithmetic must be used in many cases. The new suitable parallel algorithm based on implicit Taylor series method with recurrent calculation of Taylor series terms and Newton iteration method (ITMRN) is proposed.

Vývoj metodologické a technologické platformy pro neinvazivní odhad fenolických látek v listech a bobulích
ŠEBELA, David
Plant optical signals can serve as important source of information about biochemical and physiological processes in plants. These signals are influenced by compounds synthesized by plants during primary or secondary metabolism and thus, can also serve as their qualitative and quantitative indicators. Light reaching plant surface (leaf or fruit) can undergo three main pathways- it can be (i) reflected, (ii) absorbed or it can (iii) transmit through plant material. The probability of these three processes depends on particular wavelength of incident irradiation and on the morphological characteristics of plant tissues themselves. As such, plant contains various spectrum of photosynthetic pigments and fluorescent compounds which can either reflect, absorb or pass incident irradiation through at specific wavelengths. Biophysical techniques working with these optical properties of plant pigments and/or other compounds have become universal and common tool in basic and applied research. To quote some example, chlorophyll fluorescence imaging, UV induced fluorescence or spectroscopic techniques are on the top of interest thanks to its non-invasive nature, allowing maintain the integrity of measured cells or the whole plant constituents. The main aim of this thesis is to provide a comprehensive study on the possibility of non-invasive monitoring of phenolic compounds in the leaves and fruits.

The role of a nurse in a prevention and a treatment of intestinal parasites of children
JANDOVÁ, Anna
The best-known intestinal parasites are Pinworms, Roundworms, Tapeworms and the disease called Toxocarosis. The oftenest parasite is, according to sources, the Pinworm. Intestinal parasites affect mostly young children of pre-school age, sometimes even older. The first goal of the thesis was to investigate parents' awareness of the prevention of parasitic diseases in children. There is a hypothesis set to this goal: Parents of children who suffered from parasitic disease are more informed than parents of children who have not had this disease. The second goal was to map the specifics of nursing care for children with parasitic diseases at GPCHA practice. A research question was chosen for this aim: What are the specifics of nursing care at GPCHA in parasitic diseases? In methodology, the empirical part was chosen and it was a qualitative - quantitative research survey. For the quantitative part, the interrogation method and technique of non-standardized questionnaire was used. The research sample of quantitative survey consisted of 223 respondents, it means parents whose child is aged from 0 to 6 years. The questionnaires were distributed on social networking and others in a nursery school in Týn nad Vltavou. At the very beginning, respondents were acquainted with the topic of the thesis. The results of a quantitative survey were processed with the help of a data matrix and were further processed within twenty-arranged bar charts. To verify the hypothesis, we used the Chi- Quadrat test, which in this case is not satisfactory, therefore, there had to be chosen to merge the responses. An interrogation method, technique-depth interview was used in the qualitative part. The research group consisted of five nurses; three nurses working at GPCHA in Týn nad Vltavou and two working at GPCHA in České Budějovice. While processing the interviews, there open coding was used and an analysis of interviews was conducted by using the method of Pencil and Paper Interview. The results of this bachelor thesis will be published in the journal Paediatrics practice.

History of critical and intensive care - past and present
HOVORKOVÁ, Nicole
The title of the bachelor thesis is "History of critical and intensive care - past and present". Its main aim is to describe its origins in order to explore the history of providing critical and intensive care, both in the Czech Republic and in a global context, and also in comparison to the current state of the medical field. This work is focused on the period of development of intensive care, from the 50s to the 80s. It is a theoretical work done by detailed research of secondary and primary sources. It is divided into two parts. The first is dedicated to intensive care and its global development and in the Czech Republic. The second part contains data about intensive care within the hospitals of South Bohemia, which I have gathered during the study of materials provided by the local archives. The first chapter and the second chapter is dedicated to the history of nursing, both worldwide and in the Czech Republic. It serves for better orientation in the next chapter. The third chapter deals with intensive care itself. It is described in many of its aspects and in its historical and global context. The fourth chapter brings us to the second part of the thesis, which is supplemented with information from archival materials found during the research in regional archives. The thesis includes some photos that were captured either during a visit to the Museum of the National Medical Library, or during visits to the archives.
