Using Game Mechanics Outside Games
Berlinger, Michal ; KOPECKÝ, Lubor (advisor) ; VLACH, Jiří (referee)
The work is divided into two parts. The first is devoted to theoretical introduction to the use of game mechanics or gamification. The second part describes the design, implementation and evaluation of my practical application of game elements in ARGO association. The results indicate some positive changes in people behavior, but not all parameters were shown utilizable due to the size of the data sample.

Reprodukce a intenzivní chov juvenilních ryb štiky obecné (Esox lucius L.)
BONDARENKO, Volodymyr
Fish hatcheries do not always provide optimal conditions for controlled reproduction and production of high-quality juvenile in northern pike. This study was undertaken to optimize reproduction and intensive juvenile culture of northern pike (Esox lucius L.) under controlled conditions. The efficacy of traditional treatments for induction and synchronization of ovulation in northern pike (carp pituitary or ambient outdoor conditions) was compared to that of sGnRH-a at 50 and 100 ?g kg-1 with or without Freund´s incomplete adjuvant and dopamine inhibitor (metoclopramide, 8 mg kg-1). Ovulation was observed in females treated with carp pituitary (3 mg kg-1) and in those held in ambient conditions. Sperm motility parameters were compared in northern pike and sterlet (Acipenser ruthenus Brandt). Analysis was accomplished via high speed video microscopy complemented with CASA analysis. This work described recently developed methods of recognizing and quantifying sperm quality. The data obtained will lead to more accurate modeling of flagellum behavior during the motility period and provide a deeper understanding of basis of spermatozoa motility. The effect of water temperature on duration of embryo ontogenesis and hatching period; fertilization and development to the gastrula stage; hatching rates; and quality of larvae including larval size, development, and resistance to osmotic stress under controlled conditions for northern pike were investigated. Results indicated that the optimal temperature range for northern pike embryo development under controlled conditions is 6-10oC. Northern pike embryonic development hypothetically ceases at approximately 3.3 °C. In the certified methodology the basic aspects of controlled reproduction of northern pike was described and explained, including optimization of broodstock management. An objective of the certified methodology was to describe methods for producing high quality juveniles.

Reproductive Strategies of Geckos: The Role of Macroevolutionary Novelties and Phenotypic Plasticity
Kubička, Lukáš ; Kratochvíl, Lukáš (advisor) ; Rehák, Ivan (referee) ; Boukal, David (referee)
Presented Ph.D. thesis contains an introduction and four chapters concerning reproductive strategies in geckos. The chapters include four peer-reviewed papers and a submitted manuscript. All geckos share rather exceptional reproductive trait known as invariant clutch size, which is characterised by low and invariable clutch size. The first chapter demonstrates that invariant clutch size probably evolved in geckos under selection for enlargement of investment per offspring. On the other hand, in anoles (a group not related to geckos possessing the same mode of reproduction) invariant clutch size allowed considerable decrease of female reproductive burden. Moreover, the interspecific allometries of egg mass and clutch mass in anoles and geckos are informative for understanding of reproductive allometries in a broader context of squamate reptiles. The second chapter is focused on a trade-off in energy investment among reproduction, growth and fat storage in a gecko Paroedura picta. Surprisingly, there seems to exist a clear hierarchical rule for allocation among particular life-history traits. Effect of temperature on reproductive rate in the same species of gecko is the subject of the third chapter. Observed thermal dependence is in contrast to the general relationship suggested under the so-called...

Investigation of matter transport in porous materials by means of PFG NMR
Peksa, Mikuláš ; Lang, Jan (advisor) ; Hof, Martin (referee)
Title: Investigation of matter transport by means of PFG NMR Author: Mikuláš Peksa Department of low temperature physics Supervisor: doc. RNDr. Jan Lang, Ph.D. Assistant Supervisor: RNDr. Milan Kočiřík, CSc. (ÚFCH JH AV ČR) Abstract: Estimation of transport-structural parameters such as porosity, tortuosity and surface-to-volume ratio of pores in beds of glass beads is the main goal of this study. These parameters were estimated for 5 samples with different distributions of sizes. The second goal is to probe a possibility to use the same approach to describe the self-diffusion in water solution of LiCl confined in two porous materials based on Al2O3 and glass, respectively. The last goal is the measurement of self-diffusion of water molecules in mesoporous geopolymeric material. Its capability of water transport at long scales have been documented. The measurements of apparent self-diffusion coefficients by means of NMR spectroscopy with pulsed field gradients was major methodology of this work. Keywords: porous material, porosity, tortuosity, self-diffusion, NMR

The influence of reducing agent on silver nanoparticles granumetric parameters
Šomodíková, Iva ; Dittrich, Milan (advisor) ; Šnejdrová, Eva (referee)
We report an experimental evidence of a process of silver particles preparation by the Tollens reduction method. Natural non toxic reducing agents, such as various starches and flavonoid plant extracts were used. As the most efficient reducing agents amaranth starch and Paulinia cupana extract were choosen for the following study. The use of starches alone leads to highly polydisperse systems. The mixing of starches with Paulinia cupana extract results in silver nanoparticles with good size-mean and size-distribution parameters. The nucleation and growth phase of the particle preparation process were improved by the microwave irradiation. The synergy of intensified molecular movement in the water phase and the similar and more thermal accented process in the newly formed metal nanoparticles were exploited. This preparation method evidently leads to the higher quality systems usable as biocompatible antimicrobials and preservatives.

Calculus Bovis effect on blood lipids and the expression of endothelial NO synthesis / / in ApoE-deficient mouse model of atherosclerosis
Studená, Romana ; Nachtigal, Petr (advisor) ; Trejtnar, František (referee)
Calculus Bovis is one of the most precious and commonly-used medicinal materials in China. It is consists predominantly bilirubin and bile acids. In this thesis we focused on possible effects of Calculus Bovis on lipids and atherogenesis in apoE-deficient mice. ApoE-deficient mice were fed standard diet for 2 weeks. At the age of 8 weeks the control group of animals were fed with the western type diet, which contained 21% fat and 0,15% cholesterol for 8 weeks. The same atherogenic diet was used in Calculus Bovis group, where Calculus Bovis was added to the atherogenic diet at the dosage of 50 mg/kg b.wt. Calculus Bovis (Artificial bezoar, Biopharma, Australia) per day. The biochemical analysis of lipid spectrum was done, area of atherosclerotic lesions was determined and imunohistochemical and stereological analysis of eNOS expression was performed as well. Calculus bovis treatment did not affect blood lipids, total cholesterol, VLDL, LDL, HDL and TAG when compared with control mice. Moreover Calculus bovis treatment did not decrease either atherosclerotic plaque area or endothelial expression of eNOS. The failure of Calculus Bovis treatment in this pilot study could be probably related to insufficient dose of Calculus Bovis.

Storing system analyse of chosen subject
SCHACHERLOVÁ, Šárka
The aim of this Bachelor{\crq}s thesis is to analyse store and storing system of company Transforwarding, a.s. As main subject for analysis I chose store České Budějovice, because it was the first store of this company. Next, I analysed store Praha-Horní Počernice, because it is new and the most modern store of whole net. I compared both stores with each other. There are discussed parameters of stores like location, function, construction, flow of goods and size. The communication in and out of company proceeds mostly in frame of EDI system, which makes work fast and easy. The advantage for customers is that they can watch their goods on web sides in on-line store and they can give commands, e.g. store out the goods command. In my thesis I mention also information about store{\crq}s staff, complaints and insurence and other services (completation of goods, transport of goods, colective service, INTRASTAT).

Expenses for Public Green Space as a Function of Various Parameters of Municipalities in the Czech Republik for 2011
Mrkvičková, Ivana ; Vejchodská, Eliška (advisor) ; Ropický, Jan (referee)
Greenery in towns and cities are an important part of our lives and influences us in many positive ways. In the Czech Republic, the establishment, restoration and maintenance of public green areas within the competence of municipalities. As with every other public service there arises a problem with the quantity and quality of its provision. This paper deals with the relationships that developed in 2011 between spending on public greenery and various parameters of the municipalities. These relations are implemented by means of two hypotheses. The first is based on economies of scale, and assumes that the larger the municipality, the smaller expenses should be provided for public green areas per inhabitant. The second hypothesis is based on the work of Carruthers and Úlfarsson (2008) and says that a higher the population density reduces the per capita expenditures of city govenments. The validity assessment of the hypotheses is done by use of the statistical method of regression analysis. This, however, did not confirm the validity of any of them. Thus there is no indirect relationship between the size of the municipality or population density and public expenditures on green areas per capita. The reason why there is no relationship lies primarily in the great freedom of decision-making of individual municipalities, as far as public green is concerned.

Spirulina platensis effects on atherogenesis in mouse model of atherosclerosis.
Hanusová, Kateřina ; Mičuda, Stanislav (referee) ; Nachtigal, Petr (advisor)
Spirulina platensis is a single cell blue-green algae of Cyanobacteria strain. Spirulina belongs among foodstuffs with the highest protein content and contains all essential amino-acids. It is also a source of some non essential amino-acids, important nutrients as for example gamma linol acid, a lot of vitamins (B1, B2, B6, biotin, etc.) and trace elements (e.g. selenium, chrome, iron, calcium). Moreover it contains natural pigments carotenoids, chlorophyll and phycocyanin. The aim of this thesis was to test potential hypolipidemic and anti- inflammatory effects of Spirulina platensis on an experimental animal model of apoE/LDLr deficient mice. Therefore the parameters of lipid spectrum in blood and VCAM-1 expressions in arterial endothelium were monitored. Mice with deficit of apolipoprotein E (apoE-/- ) and LDL receptor were weaned of and for two weeks fed with a standard diet. At the age of eight weeks they started to be fed with atherogenic diet containing 0.15% of cholesterol. This continued for eight weeks (control group). In Spirulina platensis group the mice were fed with the same atherogenic diet with daily addition of 20 mg of Spirulina platensis. Biochemical analysis of lipid spectrum as well as histochemical and imunohistochemical analyses of atherosclerotic plates and VCAM-1...
