Case Study - Divorce and its conditions
Kopecká, Veronika ; Spirit, Michal (advisor) ; Jansa, Viktor (referee)
This bachelor thesis centers around divorce issues and its circumstances, which is illustratively demostrated on a real life scenario. For meeting my aims, that is to introduce and characterise divorce as a phenomenon with huge amount of negative social-economical and social-psychological results including causes and mechanisms of divorced family and breakup of marriage, I used a literature that examines this area, followed by comparison of acquired data with a case study. In this thesis, an assumption of negative results of a divorce has been comfirmed, but so has the work of a state to effectively separate a married couple. The benefit of this thesis lies in an opportunity to get acquinted with requisities of a divorced marriage and should the reader be in similar situation when a divorce is imminent or planned for, he can take proper steps by familiarizing with circumstances and results of a divorce.

Optical frequency references
Hrabina, Jan
Optical frequency references based on absorption cells represent a traditional and essential tool for frequency locking of precise laser standards. One of the most often used absorption media is a molecular iodine 127I2, which offers a rich atlas of strong and narrow absorption lines across mostly whole visible part of optical spectrum. The main disadvatage of this media can be seen in its high corrosivity and sensitivity to presence of foreign substances. This contribution is oriented to comparison of possible measurement methods for bulk- and also optical fiber- based iodine absorption cells quality and chemical purity testing.\n\n

Cell culture-based model for the evaluation of adhesive properties of probiotic bacteria
Theodorou, Vasiliki ; Havlík, Jaroslav (advisor) ; Tauchen, Jan (referee)
Probiotic microorganisms, defined as living microorganisms which when administered in adequate amounts confer a health benefit to the host, and their adhesion and colonization of intestinal epithelium, are critical factors in maintaining probiotic efficacy. Polyphenols are a large and heterogeneous group of phytochemicals in plant-based foods, such as tea, coffee, wine, cocoa, cereal grains, soy, fruits and berries. In the last decade, there has been much interest in the health benefits of dietary plant polyphenols that arise from their potential ability to promote adhesion of probiotic bacteria to the human intestinal epithelium.
The purpose of this study was to investigate the effect of four polyphenols: isoquercetrin, phloretin, procyanidin B2 and rutin on the adhesion ability of two potentially probiotic strains (Lactobacillus casei, Lactobacillus gasseri) to in vitro human intestinal epithelial model consisting of Caco-2 and mucus-secreting HT29-MTX co-culture.
The adhesion of Lactobacillus casei after treating the co-culture cell lines with isoquercetrin, phloretin, and rutin was increased by 49.76, 72.97, 63.66 % respectively, whereas procyanidin B2 inhibited the adhesion 20.25% compared with the control sample. The adhesion of Lactobacillus gasseri after treatment of the co-culture with isoquercetrin, phloretin, procyanidin B2 and rutin was increased by 35.45, 31.28, 45.69, 25.01 % respectively compared with the control sample.

Evaluation of a management working style
Matejková, Renáta ; Hron, Jan (advisor) ; Fajčíková, Adéla (referee)
This thesis with a focus on "Evaluation of manager's management style" deals with managing styles that have been defined by its typical characteristics and described in the expertise literature. Individual styles of the senior personnel on their subordinate colleagues affect each individual in the team and also the overall outcome and meeting the deadline for completion of tasks. In the first part of the thesis are described specific types of management styles and their characteristics, typology of managers, their role in management and its history.
The second part of the thesis leverages on theoretical knowledge and it evaluates specific control style for the three executives in the company Folklore Garden s.r.o .. These executives manage the same team of subordinates and should reach approximately the same performance results. In the practical part there was used survey with specific questionnaire. This part includes comparison of results referring to the prevailing management style of particular manager in terms of superior and subordinate workers but also from the manager himself. The result is evaluated through a managerial grid model.
In the last part of the thesis there are mentioned opportunities for further qualitative and personal development of individual managers to avoid constant personnel changes that are for the company both financially inefficient and time-consuming.

Assess the current state of nutrition of horses in the specific stables and proposal optimal doses according to the their performance
Burcalová, Helena ; Mudřík, Zdeněk (advisor) ; Václav, Václav (referee)
This work deals with calculations of feed rations of selected thoroughbred horses at the High School of Horse Racing in Prague together with an assessment of economic aspects of horse feeding. The school is mainly focused on the education of jockeys, which means that the work with horses has to conform to the school requirements that need not meet the ideal feeding rhythm of the horses.
United Kingdom norms were compared to the selected Czech norms. Focus was mainly on the racing season, which provides direct comparison of the feed rations with the horses results in the races. The racing season has the highest energetic requirements that need to take into account not only the requirements for the races themselves but also for the resting periods. Feed rations were measured and fed in precise time intervals. Main feeds were oats, hay, bran and Spillers feeds.
During the assessment period a negative side - effect of high temperatures during consecutive heat - wave periods was observed. This aspect may prove important in the future and needs to be taken into account not only for feeding but for the entire horse training.
Out of five examined horses, exceedance of digestible energy requirements was observed with two horses and underestimation with one horse. For two of them the anomaly was in norm. However, the horse with the highest exceedance was experiencing difficulties with feeding, always leaving a part of the ration intact. This made it necessary to adapt the rations to a higher figure than calculated.
Economic aspect of horse feeding needs to be taken into account. The feeding expenses can be decreased by a suitable selection of a feeding mix, however the savings in this regard are not fundamental.

Biotransfer of selected risk metals into plants and their accumulation and distribution in plant organs
Le Minh, Phuong ; Lachman, Jaromír (advisor)
Contamination of soils with heavy metals is one of the serious environmental problems threatening human being. Heavy metals are considered as the special hazard of soil pollutants because of the adverse effects on the plant growth, the amount, activity of useful microorganisms in soils and the quality of food. Regard to the persistent and toxicity, the heavy metals are toxic when we consider different kinds of pollutants in soils. In the soil, zinc (Zn), cadmium (Cd), lead (Pb) and mercury (Hg) toxicities frequently occur than the other metals because of their precipitation and sorption by the soil. It is a very dangerous situation because when these metals are taken up by plants, they can be transported to the food web and food chains.
In the present study, the accumulation of four heavy metals (mercury, zinc, lead and cadmium) in the whole grain of spring accessions of emmer, einkorn and common spring wheat cultivars and potato (Solanum tuberosum) is reported. Heavy and essential elements were monitored in potato cultivars in the exact field experiments and in hydroponically grown plants. The elements were determined by methods FAAS, ET AAS, and AMA (Advance Mercury Analysis). Statistical analyses were performed using SPSS 9.0 with the Tukey HSD (Honestly Significant Difference) test (alpha equal to 0.05).
In our study, the concentration of heavy metals decreased in the order zinc (Zn) > lead (Pb) > cadmium (Cd) > mercury (Hg) in the wheat grain. The comparison between three varieties of investigated wheat revealed that the emmer wheat was rich in zinc content (62.12 mg kg-1 dry matter), while the spring wheat had the lowest average concentration of zinc in the grain (40.99 mg kg-1 dry matter). Generally, the values of lead concentration in grain wheat varieties were low (ranging from 0.1268 mg kg-1 dry matter to 0.2950 mg kg-1 dry matter).
The concentrations of mercury in four typical growth stages of wheat (boot stage 10, heading stage 10.2 1/4 of head emerged, leaf-stage 10.2 and stage ripening 11 according to Feekes) were also determined. It has been shown that the concentrations of mercury in different wheat varieties were absorbed differently at different growth stages of plant. Stage 10.2 and leaf stage 10.2 showed the high mercury content (0.0152 mg kg-1 dry matter and 0.0214 mg kg-1 dry matter, respectively). Among individual varieties significant differences were determined.
Amounts of toxic and potentially toxic elements detected in investigated potato tubers are characterized by a large variability within investigated groups. Performing statistical analysis (one way ANOVA) showed that there were no significant differences between two investigated groups of samples (samples from Uhříněves and Valečov in the year 2013 and 2014) considering either one of investigated metals. Measurable levels of mercury were found in smallest amounts in all investigated potato samples comparing to other metals (Cd, Pb).
Plant cells compared to animal cells are characterized by the formation of cell walls. Plasma membrane or cell membrane is a biological active membrane separating the interior of cell from the outside environment. An adjusted method for isolation of protoplasts was developed and adapted for isolation of protoplasts from plant material (potatoes). In our experiment, the plants were grown hydroponically in the Research Institute of Plant Crops Prague-Ruzyně. If we examine the plant membrane, one option is to remove the cell wall by means of special mixture enzymes. Protoplasts were released in the dark at 25 degrees of Celsius for 18 hours. The 70 and 90 microns sieve was used to filter and then centrifugation for 5 minutes at 100 x g. All the steps were carefully carried out to prevent the damage or breakage of protoplasts.

Assessment of in vitro antioxidant properties of medicinal and edible plant extracts
Tauchen, Jan ; Kokoška, Ladislav (advisor) ; Jaromír , Jaromír (referee)
Identification and characterization of plant-based products with antioxidant and anti-proliferative effects has received much interest over the past few years as possible therapeutic mean for treatment of diseases likely to be associated to oxidative stress (such as atherosclerosis, diabetes, and cancer). This study provides characterization of in vitro antioxidant and/or anti-proliferative potential and phytochemical profile of (i) 39 wine samples of underutilized Georgian grapevine cultivars, (ii) extracts of 22 samples of medicinal plants from Ethiopia and (iii) 23 samples of edible and medicinal plants from Peruvian Amazon. For this purpose, 2,2-diphenyl-1-picrylhydrazyl radical assay (DPPH), oxygen radical absorbance capacity (ORAC) assay, total phenolic content (TPC), and cell viability assay based on metabolization of tetrazolium bromide (MTT) to formazan, together with methods based on high performance liquid chromatography (HPLC-ultra violet/visible spectrometry and HPLC-tandem mass spectrometry) were used. Georgian red wines (particularly Saperavi cultivars) exhibited higher antioxidant capacity (average DPPH and ORAC values at 5.1 and = 10.6 g TE/L wine, respectively) in comparison to Central and West European cultivars [Pinot Noir (DPPH = 3.1 and ORAC = 9.4 g TE/L wine), Cabernet Sauvignon (DPPH = 3.0 and ORAC = 7.3 g TE/L wine) and Cabernet Moravia (DPPH = 2.0 and ORAC = 8.5 g TE/L wine)]. Georgian wines contained significantly greater concentrations of quercetin (between 14.44 and 1.07 ug/mL), kaempferol (between 1.68 and 0.03 ug/mL) and syringic acid (between 12.59 and 4.72 ug/mL), whereas possessed lower quantities of resveratrol (between 5.11 and 0.32 ug/mL) in comparison to Central and West European wines. Amongst edible and medicinal plants from Ethiopia and Peruvian Amazon, only Dodonaea angustifolia (IC50 for DPPH = 22.2 ug/mL, ORAC = 767.6 ug TE/mg extract; IC50 for Hep-G2 = 120.0 ug/mL), Rumex nepalensis (IC50 for DPPH = 5.7 ug/mL, ORAC = 1061.4 ug TE/mg extract; IC50 for Hep-G2 = 50.5 ug/mL), Inga edulis (DPPH and ORAC = 337.0 and 795.7 ug TE/mg extract; IC50 for Hep-G2 and HT-29 = 36.3 and 57.9 ug/mL) and Oenocarpus bataua (DPPH and ORAC = 903.8 and 1024.4 ug TE/mg extract; IC50 for Hep-G2 and HT-29 = 102.6 and 38.8 ug/mL) have demonstrated combinatory antioxidant/anti-proliferative efficacy. Selective anti-proliferative activity was observed for Verbascum sinaiticum (IC50 for Hep-G2 = 80.6 ug/mL) and Annona montana (IC50 for Hep-G2 and HT-29 = 2.7 and 9.0 ug/mL, respectively). Above-mentioned plant material showed only weak or non-toxic effects towards normal cell line. Despite the fact that extracts of Jasminum abyssinicum (IC50 for DPPH = 26.3 ug/mL, ORAC = 1023.7 ug TE/mg extract), Rumex nepalensis (IC50 for DPPH = 5.7 ug/mL, ORAC = 1061.4 ug TE/mg extract), Mauritia flexuosa (DPPH and ORAC = 1062.9 and 645.9 ug TE/mg extract), Myrciaria dubia (DPPH and ORAC = 641.9 and 642.6 ug TE/mg extract) and Theobroma grandiflorum (DPPH and ORAC = 714.8 and 821.9 ug TE/mg extract) have exhibited considerable antioxidant effect, these species were found to possess moderate to low anti-proliferative potential or have shown to be toxic to normal cells line. In all cases it was detected that phenolic compounds content correlated strongly with antioxidant activity, however weakly with anti-proliferative effect. Results suggest above-mentioned species as prospective materials for further development of novel plant-based agents effective against oxidative stress related diseases. However, it is necessary to perform further research which would be focused on detailed characterization of their chemical composition, pharmacological effects and toxicological safety, in order to verify their possible practical use.
