Sign Writing
Václavíková, Jitka ; Okrouhlíková, Lenka (advisor) ; Macurová, Alena (referee)
This bachelor's thesis examines the SignWriting notation system and its application for Czech Sign Language. SignWriting is a notation system that allows for graphical representation of sign languages. Due to the simultaneous articulation in the manual-visual modality of sign languages, sign language notation systems are very different from those used for spoken (audio-oral) languages. Sign languages contain manual and non-manual elements all of which can be represented in SignWriting using pictorial (iconic) symbols. The introductory chapters of this thesis describe the origins and progressive transformation of SignWriting, its basic principles and the method of individual symbol formation. Further, the thesis introduces specific symbols used for the manual components of signs - place of articulation, handshape, movement and body contact, non-manual components of signs - body movement and position, facial expressions and mouthing, and the use of punctuation symbols. The last chapter discusses the use of SignWriting in the Czech Republic and worldwide.

Study of physiological changes in plants under stress by zinc ions
Adam, Rostislav ; Soudek, Petr (advisor) ; Petrová, Šárka (referee)
Heavy metals are part of us life for many centuries. Some of them are for living organism neccessary, but in large amount they have toxic effects. So we should decrease amount of heavy metals in the Environment. We have many way to do it. A relatively new way are the phytoremediation. If we would use the phytoremediation, we should know, what they do in plants. We must use specific plants, which are tolerant to certain heavy metal. If we would select a suitable plant, we have to try, how heavy metals in soil solution are toxic to plants. Zinc is no expection, although it is important part of many proteins. In plants it make rusty leaves and reduct aboveground and root biomass production. In hydroponic experiment I investigated that mallow Malva verticillata was very sensitive to low additon of Zn(NO3)2. The toxic efect appeared in 2 weeks. In sorghum Sorghum bicolor zinc show expressive toxic effect at concentration 1 mmol/l. I studied six cultivars of Sorghum bicolor, DSM 14-535, Expres, Honey Graze BMR, Nutri Honey, Sucrosorgho 506 and Sweet Virginia. According EC50 I as- sessed that the most sensitive was Sucrosorgho 506 and very tolerant were Nutri Honey and Sweet Virginia. Cultivar Nutri Honey was characteristic. It had the highest ratio concentration in shoot to concentration in root. I studied...

Financial analysis of Spanish companies
Exlerová, Lenka ; Marek, Petr (advisor) ; Dufková, Eva (referee)
This thesis focuses on the financial analysis of selected industrial sectors in the Spanish economy. For the purposes of analysis the following indicators are used: return on assets, return on equity, inventory turnover, receivables and payables turnover ratios and trade gap derived from them. Then indicators of current ratio, acid test ratio, cash ratio and working capital are analyzed. Finally the thesis includes indicators of creditor's risk, interest coverage and total cost and expenses per revenues. A further part of the thesis is dedicated to the peculiarities of the Spanish economy and the studies of changes in the unemployment rate and gross domestic product. A significant part is devoted to particular sectors of economy. Spanish exports and imports are presented by means of the balance of payments. After interpretation of all calculated indicators the following conclusion has expressed: the best performing sectors are the manufacture of coke, refined petroleum products and nuclear fuel followed by sector of construction. On the other hand traditional Spanish fishing, fish farming and related service activities were found to be the worst performing sectors.

Gen expresion of high affinity choline transporter in mouse model of Alzheimer's disease
Kurfürst, Helena ; Krištofíková, Zdena (referee) ; Doležal, Vladimír (advisor)
: Choline is being used in all mammalian cells as a precursor for synthesis of a major phospholipide phosphatidylcholine and as a donor of acetyl residues. Cholinergic neurons in addition require choline to synthesize neuromediator acetylcholine. The ability of cells to create choline via de novo synthesis is limited and therefore they need to transport choline from extracellular space. Limited availability of choline in brain leads specifically to diminished function of cholinergic neurons and in general to impaired reparation of biological membranes. Dysfunctions of cholinergic signaling in brain is characteristic for Alzheimer's disease. Aim of this work was to investigate whether gene and protein expression of high- affinity cholinergic transporters is altered in 5-6 months old APPswe/PS1dE9 mouse model of Alzheimer's disease. Expression of specific high-affinity cholinergic transporter CHT1 (responsible for transport of choline to be used for acetylcholine synthesis) and putative high-afinity choline transporter CTL1 (generally present in all cells and related to high affinity choline transport for phospholipide synthesis) in cerebral cortex was measured. Compared to non-trangenic littermates, no changes in the expression of both genes were detected at either mRNA (quantitative PCR) or protein...

Effect of various plasma sources on seed growth. Laboratory experimen in Buckwheat
Šerá, Božena ; Gajdová, Iveta ; Čermák, M. ; Gavril, B. ; Hnatiuc, E. ; Kováčik, D. ; Kříha, V. ; Sláma, J. ; Šerý, M. ; Špatenka, P.
Germination and early growth of buckwheat (Fagopyrum aesculentum) after low-temperature plasma discharge treatment in air gas generated in various apparatus were tested. Three pretreatment times were used: 180 s, 300 s and 600 s. Number of germinating achene, length and weight of sprouts were measured. The data was analysed with two-way ANOVA. A significant influence of the type of plasma apparatus, time of exposure and combination of both factors were found. The positive effect on germination and early growth was observed after application of GlidArc plasma. The opposite effect of PDBV apparatus, which is characterized by plasma with a high power density, was observed. Shorter pre-treatment times for this apparatus must be therefore used.

Effect of cancer-associated fibroblasts on the survival, proliferation and invasiveness of cancer cells.
Nováková, Gita ; Anděra, Ladislav (advisor) ; Brábek, Jan (referee)
Tumour microenvironment, in addition to cancer cells themselves, represents important structural and functional part of the tumour. Similarly to the normal organs tumour microenvironment comprises several cell types (fibroblasts, immune cells, endothelial cells etc.) and non-cellular components, particularly extracellular matrix. All of them form favourable conditions for the growth, proliferation, protection from the immune system- mediated destruction and nutrition of cancer cells. Cancer associated fibroblasts (CAFs) represent the most abundant cell type of tumour microenvironment. Their origin can be traced to local normal fibroblasts, endothelial cells or epithelial cells and the transition into the CAFs phenotype is influenced with several factors secreted by cancer cells (particularly TGF-β). In contrast to fibroblasts activated during wound healing newly formed cancer associated fibroblasts expressing α-SMA are not subsequently eliminated from the respektive tissue. They persist and produce a number of pro-tumorigenic factors - SDF-1, HGF, IGF-1, IL-6, VEGF, PDGF-C, TGF-β, MMPs etc. CAFs and their secreted factors target several signalling pathways enhancing basic characteristics of the tumour, so called Hallmarks of Cancer. Cancer associated fibroblasts promote proliferation and invasiveness of...

Old Testament Interpretation and the Postmodern Conditions
Zatroch, Ondrej ; Lukeš, Jiří (advisor) ; Biernot, David (referee)
The task of diploma thesis "Old Testament Interpretation and the Postmodern Conditions" is to critically reflect the course and current issues of Old Testament research. This reflection is based on the analysis of research situation and chosen approaches to the Old Testament. The thesis shows, that the Old Testament interpretation must be based on lively dialogue. It doesn't mean just the dialogue with the biblical texts or the state of current research, but also with the situation of the world often called as "postmodern". The important assumption of this diploma thesis is that the authentic interpretation includes also the constant and deep self-examination of interpreter and his place in the society. It doesn't mean, that the interpretation ought to be the self-presentation of interpreter. On the contrary, it should remain critical and solid, but also enacted in deep solidarity with the neighbour and shared world. The results of this diploma thesis show the importance of keeping the critical grounds of Old Testament research and interpretation. Only the intensive and unappealing criticism could be a basis for the future quality and solidness of the research and upholding its matter in wider research community and society. Another important aspect is the solidarity with the world. It means that...

Important roles of heme as a signal and a gas-sensing site: heme-sensing and gas-sensing proteins
Fojtíková, Veronika ; Martínková, Markéta (advisor) ; Hudeček, Jiří (referee)
Heme-containing sensor proteins are heme proteins, which are divided into two groups: heme-sensing and gas-sensing proteins. The function of heme-sensing proteins is affected by heme availability. Association (or dissociation) of heme moiety of heme-sensing protein regulates various physiological functions, including protein kinase activity, transcription and other important functions essential for cell survival. In gas-sensing proteins, heme acts as the sensing site for binding of gaseous molecules (including O2, NO and CO) and indirectly regulates physiological functions, including protein kinase activity, transcription and other important functions essential for cell survival. The recent studies on heme-containing senzor proteins published in scientific journals are summarized in this thesis. The experimental part of this thesis focused on the specific heme-containing sensor protein - a globin-coupled histidine kinase from Anaeromyxobacter sp. strain Fw 109-5 (AfGcHK). The aim of this thesis was to amplified and isolate plasmid carrying gen for AfGcHK. Consequently the protein was expressed in E.coli BL-21(DE3) and the protein was isolated. Based on the results, the isolation process was optimized. Moreover, the purified preparation of isolated AfGcHK was prepared in more than 99% of homogeneity....

Vavríková, Katarína ; Novák, Radek (advisor) ; Pajmová, Šárka (referee)
Currently, logistics is considered as one of the most dynamic sector and therefore it should be given considerable attention. With the current trend of the globalization, we can expect increasing tendency in the near future. Logistics as we know it today has been really an indispensable part of our daily lives. All these activities are covered by logistics processes, without which we cannot imagine the modern life as we know it today.The aim of my thesis is to describe and analyze services and product lines of DHL Express (Czech Republic) Ltd. I chose this topic because I worked in the company and therefore I know the internal conditions and thus can approach the issue comprehensively. The main focus is on description and assessment of existing services DHL Express in the theoretical part. In the practical part, I would like to analyze the new, introducing the services that DHL recently applied or only will implement in the near future. It is for example the Service Point or modern service on petrol station related with expenditure shipments. Outputs of my final project should be beneficial also for the company itself. They are recommendations which services are most used and on the other hand should be turn down or improved. The arguments and opinions in the thesis are supported also by the questionnaire.
