Effect of recombinant toxin Cry3Aa on development of \kur{Spodoptera littoralis}
HUSÁKOVÁ, Jana
This bachelor thesis compares the effect of recombinant and natural Bacillus thuringiensis Cry3Aa toxin upon the development of non-target insect Spodoptera littoralis (Lepidoptera, Noctuidae). Caterpillars of Spodoptera littoralis were fed with Premix artificial diet containing both toxins in 8 ppm concentration. Following characteristics were monitored: weight of larval increments, pupal weight, duration of the 5th, the 6th, prepupal and pupal instar, number of laid eggs and number of hatched larvae. The efficiency of conversion of ingested food (ECI) was calculated and growth curves were constructed. No significant effect of both toxins was recorded.

Moment-tensor inversion of earthquakes in Greece, method ISOLA
Červinková, Dana ; Šílený, Jan (referee) ; Zahradník, Jiří (advisor)
3 Title: Moment-tensor inversion of earthquakes in Greece, method ISOLA Author: Dana Červinková Department: Department of Geophysics Supervisor: Prof. RNDr. Jiří Zahradník, DrSc. Supervisor's e-mail address: jz@karel.troja.mff.cuni.cz Abstract: The possibility of obtaining a reliable moment tensor using a low-frequency waveform inversion from a single seismic station is studied. Deviatoric part of the moment tensor is described in usual way, using its orientation (angles strike, dip, rake), scalar seismic moment M0 and the double-couple percentage (DC%), and also by means of the coefficients of linear combination of elementary mechanisms. We estimate the formal error of the coefficients and study conditionality of the inverse problem. Data from earthquakes Trichonis (Mw = 5.2, April 2007) and Leonidio (Mw = 6.2, January 2008), Greece, are processed using software ISOLA (Sokos and Zahradník). The moment tensor is calculated from many stations and its stability is tested. This reference solution is compared to those independently obtained from single stations. Synthetic tests are performed to understand why the single-station estimates are sufficient for Trichonis, but not for Leonidio, paying attention to the focal depth, station azimuth and epicentral distance. It is found that the depth is crucial at...

The Fruit Beers Popularity in the Czech Republic
Balaštík, Milan ; Maier, Tomáš (advisor) ; Lukáš, Lukáš (referee)
The main topic of this thesis is the popularity of fruit beers in the Czech Republic. It describes a generic distribution of fruit beers, both abroad and in our country. Shows an overview of large and small manufacturers in this category in the domestic market. It focuses on the current situation flavored beer on domestic and foreign markets, according to the latest data. Based on the survey are analyzed consumer preferences in the domestic market. They are then formulated breweries general recommendations arising from the outcomes of the survey. Subsequently, using basic statistical methods detected significant correlation between the consumption of flavored beers and gender and between consumption and age of respondents. If so, then it determines the strength of this dependence. It was found that while significant correlation was demonstrated in sex exists between consumption and age of the respondents. The strength of this dependence was assessed as moderate. It was finally drafted forecast consumption of mixed drinks based on beer in the Czech Republic. The analyzed time series contained the actual annual data maintained by the Czech Beer and Malt Association from 2012 to 2015. The forecast was calculated for the next two years. It was found that consumption of mixed drinks based on beer in the future will continue to decline.

Identification of production indicators important for definition of the selection criteria in cattle breeding.
Michaličková, Monika ; Vostrý, Luboš (advisor) ; Stádník, Luděk (referee)
The aim of the study was to apply all available information (for time period 2011 to 2013) about the dual purpose cattle breeds (Simmental and Pinzgauer) to the program package ECOWEIGHT and to suggest selection criteria for Slovak dairy and cow calf production systems. The main advantages of Ph.D. thesis were the calculation of economic weights with comprehensive consideration and updating of the current farming conditions, as well as the calculation of economic weights for new traits i. e. health and residual feed intake traits. For the calculations, the bio-economic model and the most common marketing strategy for given production system were used. The main comparative advantage of Simmental and Pinzgauer breeds, were the milk yield (dairy system) and proportion of sold calves per 100 cows (cow-calf system), respectively. For the both breeds and production systems the longevity of cows was detected as the weakness. The highest proportion in cost and revenues structure for the feeding and main products was observed, respectively. For both breeds and production systems, the profit (regardless of subsidies including) was not reached. For Simmental breed in dairy and cow calf system, the highest economic importance was observed for milk yield (19.9%) and fertility of cows (22.5%), daily gain of calves till weaning (age of 100 days; 16.1%) and weight of calves at 210 days of age (14.3%) and for the longevity of cows (11.4% and 12.4%), respectively. On the other hand, for SP breed the highest relative importance was observed for daily gain till weaning (100 days of age, 20.3%) and weight of calves at 210 days (100 days of age; 20.3%), milk yield (20.2%) and weight at 120 days of age (14.4%) and for longevity of cows (10.1% and 16.8%) in dairy and cow-calf population, respectively. Based on the results of Ph.D. thesis, it could be recommended to reconsider the current breeding objectives, as well as to redefine the selection indices of dual-purpose cattle breeds in Slovakia. The emphasise should be based to growth and functional traits, with the aim to integrate preferences of consumers (environmental criterion and popularity of animal products), as well as to ensure the sustainability of animal production.

Branch text classification
Čech, Josef ; Spousta, Miroslav (referee) ; Raab, Jan (advisor)
This thesis follows up text categorization. In the first part are described several chosen algorithms for a categorization of documents - the Bayesian model, a categorization with a neural networks and a vector model. Practice part is focused on a algorithm vector model. The vector model is based on idea of two vectors. One vector represents a pattern and second a query. In our case first vector corresponds with a category and the second one with the document. Coordinates of the vector are weights of single words in the text or in the branch depends on, which vector we think about. For comparing are possible to use several procedures like Dice coefficient similarity, Jaccard coefficient or cosine similarity. In my thesis is used cosine similarity. Computing weights is based on frequency of the term in the document and on frequency of documents, which contain the term. Relevant terms are selected on Luhn simple ideas of significance words.
