Russian-Belarusian language interference in Belarus
Kalita, Inna ; Marvan, Jiří (advisor) ; Brandner, Aleš (referee) ; Hentschel, Gerd (referee)
The work is dedicated to the language situation in Belarus at the turn of the 20th and the 21st century. It presents the Belarusian language situation in the context of the East Slavic languages and in a more widespread, postcolonial language continuum which finds itself in a new development phase. The contemporary language situation in Belarus is characterized by historical interferential influence; an emphasis is put on its binary nature which may be found in all spheres, and demonstrates the inevitability of a complex analysis. The work deals with the degrees of the contemporary interference, touches upon the process of mutual influence and its impact on the contemporary East Slavic languages is studied on the example of the adaptation of "cerkovnoslovjanizm" (the language of the Orthodox Church). The aim of the work is to present a common language situation in Belarus which has been developing in the situation of asymmetrical bilingual direction. Anyway, the work doesn't claim to describe all the characteristics concerning language interference in Belarus. The real contemporary bilingual situation is described. The level of speech interference is analyzed in detail. "Trasyanka", as the type of the language used in Belarus, is described in a special chapter and it is focused at summarizing previous...

Growth of human adipose-derived stem cells on Ti-6Al-4V alloy with various surface modifications

Adipose-derived stem cells (ASCs) are of a great importance for bone tissue engineering. We compared ASCs obtained by liposuction under two pressures (-200 mmHg and -700 mmHg). The number and proliferation activity of cells isolated under -700 mmHg (ASC-H) were higher than in cells isolated under -200 mmHg (ASC-L). However, the ASC-L was more active in osteogenic differentiation, as manifested by a higher intensity of fluorescence of alkaline phosphatase and osteocalcin in these cells. The adhesion and growth of ASCs were then studied on Ti-6Al-4V samples either unmodified (K, roughness parameter R-a = 280 nm) or modified by shot blasting and tarnishing A, R-a = 200 nm), vibratory finishing (B, R-a = 100 nm) and vibratory finishing, shot blasting and polishing (C, R-a = 80 nm). All modified samples were more wettable than the K samples. On day 1 after seeding, the size of cell spreading area on some modified samples was lower than on K samples, namely on B samples in ASC-L, on B and C in ASC-H and on A in control MG-63 cells. On day 3, the cell number on some modified samples became higher than on K samples, namely on C samples (ASC-L), on B (ASC-H) and on B and C s (MG-63 cells). On day 7, the numbers of ASC-H and MG-63 cells on all modified samples evened out and became significantly higher than on K samples. On ASC-L samples, the highest cell numbers were obtained on A samples. Thus, all studied modifications of Ti-6Al-4V enhanced growth of ASCs and human osteoblast-like MG-63 cells.

Growth and differentiation of human osteoblast-like cells on TI-6AL-4V alloy modified with anodization

Titanium and its alloys are widely used as hard tissue implants for their high biocompatibility and suitable physical properties. Along with other surface treatment methods, anodization technique is known to enhance osseointegration. The aim of this study is to evaluate the adhesion, growth and osteogenic differentiation of human osteoblast-like SAOS-2 cells on Ti-6Al-4V samples anodized in electrolytes composed of a stable volume of KOH (336.48 g/l) and variable volumes of liquid glass (124.47 g/l, 84,12 g/l and 37.38 g/l; samples s5, s6 and s7, respectively). Non-anodized Ti-6Al-4V samples, cell culture polystyrene (PS) and microscopic glass coverslips served as control materials. On days 2 and 4 after seeding, the cell number did not differ significantly among the tested samples. However, on day 7, the cell number on s6 samples reached the lowest values, which could be attributed to a non-homogeneous TiO2 film on s6 samples formed during anodization. Nevertheless, the osteogenic differentiation, estimated by the intensity of fluorescence of collagen I in cells grown in a differentiation medium, was the highest on s6 samples. On s5 samples, coated with homogeneous TiO2 films, both cell numbers and intensity of fluorescence of collagen I was relatively high. The bone matrix mineralization, evaluated by Alizarin Red staining, was the highest on s5 samples in standard culture medium, and similar on all tested samples in differentiation medium. Thus, the surface modification of s5 samples could be considered the most suitable for application in bone implants.

influence of physical conditions on diffusion processes in humic gels
Marvan, Jan ; Pabst, Willi (referee) ; Klučáková, Martina (advisor)
Diploma thesis is based on diffusion processes of copper (II) ions to humic gels obtained from lignite. Solutions with various concentrations and acidity were exposed to diffusion for exact time 24 hours. After the diffusion was ended the copper (II) ionic concentration profiles of tubular gels were create and calculated total diffusion flux. The experiment showed that the higher acidity of copper (II) solution decrease an amount of immobilized Cu2+ ions to the humic gels. In comparison concentration/pH: concentration of the solution has higher influence on sorption metal ions than change of the pH.

The Bulgarian involvement in NATO (1995-2014)
Marvan, Jiří ; Eichler, Jan (advisor) ; Dubský, Zbyněk (referee)
The thesis deals with the topic of the Bulgarian foreign and security policy in the post-communist era. The theoretical part is focused on the neo-realistic concept of security, as well as the terms security policy and the matters regarding the alliance formation. In the context of European post-socialist countries and their integration with the European and Trans-Atlantic alliances, Bulgaria occupies, due to the traditional historically justified warm relations to Russia, a unique position. Another important component of this unique process is the balkanization of the Bulgarian foreign policy which concentrated on the relations with the neighboring countries -- Greece, Turkey, Romania, Serbia and the Republic of Macedonia -- at the expense of the westernization. Therefore, the attitude towards the neighbors and the relations to them with regard to their respective historical and cultural background are included as well. Only after taking into account the Balkan circumstances it is possible to study the process of the Bulgarian voyage to the full membership in NATO and the revision of the Bulgarian doctrinal documents connected with it. The thesis closes with a thorough analysis of the Bulgarian participation in out-of-area operations in Cambodia, Bosnia and Herzegovina, Kosovo, Afghanistan and Iraq including in addition to general information about these missions themselves.

Penzijní reforma a životní pojištění
Marvan, Jan ; Daňhel, Jaroslav (advisor) ; Radová, Jarmila (referee)
Diplomová práce by měla čtenáři poskytnout popis způsobu důchodového zabezpečení občanů v České republice, analýzu udržitelnosti, resp. neudržitelnosti jeho hlavní komponenty, tj. systému sociálního důchodového pojištění, podstatnou měrou se zaměřuje na příčiny toho, proč se vůbec o penzijní reformě začalo mluvit, a pracuje s životním pojištěním v kontextu penzijní reformy, která představuje víceméně nutnou reakci na současná a zejména pak velmi reálná budoucí rizika, jejichž naplnění by znamenalo ohrožení finanční stability českého důchodového pojištění a potažmo i dlouhodobé vyrovnanosti veřejných financí. Na životní pojištění je zde tedy nahlíženo jako na jeden ze zamýšlených nástrojů financování postaktivní fáze života jedince.
