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.

Determination of bisphenols in selected beverages by high-performance liquid chromatography
Marvan, Jiří ; Sobotníková, Jana (advisor) ; Olšovská, Jana (referee)
Bisphenols are chemical compounds with a wide range of uses in the chemical industry. They are used in the production of plastic materials as softeners for polymer materials or epoxy resins, as monomers in the synthesis of polycarbonates, or for the elimination of hydrochloric acid in the production of polyvinyl chloride. This thesis deals with the development, validation, and optimization of an analytical method for the determination of selected bisphenols, specifically bisphenol A, bisphenol B, bisphenol F, bisphenol A diglycidyl ether and bisphenol F diglycidyl ether (BPA, BPB, BPF, BADGE, BFDGE), and their metabolites using the high performance liquid chromatography with mass spectrometry, HPLC/MS, and the application of the method to real samples in selected canned beer samples. The following conditions were optimized for chromatographic separation. The Sigma-Aldrich discovery C18 column (150×2,1 mm, 5µm) was chosen. The mobile phase consisted of a mixture of mobile solvent A, which contained 0,05% ammonium hydroxide, and mobile solvent B, which contained of methanol. The flow rate of the mobile phase was 0,240 ml/min. The total analysis time was 22 minutes, using a 5 μl injection of the sample solution with gradient elution. Next, a partial validation of the method was performed, evaluating...

Numerals as a word class in present Ukrainian language
Poláčková, Jindra ; Lendělová, Věra (advisor) ; Marvan, Jiří (referee)
V této práci bych se chtěla věnovat číslovkám a jejich zařazení v rámci slovních druhů, historickému vývoji, srovnání se slovanskými jazyky, zejména s češtinou a ruštinou, a jejich použití v současné spisovné a hovorové ukrajinštině a jejích dialektech. Nejdříve se chci zaměřit na jednotlivá kritéria, podle kterých lze definovat slovní druh, na základě nichž chci zjistit, je- li možné vymezit číslovku jako autonomní slovní druh či nikoliv. K číslovkám se vyjádřilo bezpočet současných lingvistů a lingvistů 19. a 20. století. Proto bych chtěla zmapovat a prezentovat jejich koncepce a pohledy na číslovku a její existenci jako samostatného slovního druhu. Názory lingvistů se liší podle náhledu na číslovku aje těžké najít jednotný postoj, proto se pokusím představit různé koncepce lingvistů, v nichž představují svůj pohled na vymezení číslovky v rámci slovních druhů. Koncepce budu srovnávat ze synchronního (I. R.Vychovanec, I. K. Kučerenko, K. H. Horodens'ka) a diachronního hlediska (A. A. Potebnja, I. Verchrats'kyj, J. O. Dzendzelivs'kyj, I. P. Pankevič). Budu vycházet z práce Potebni, která je stále aktuální a zasluhuje si pozornost i v dnešní době. Jeho práce obsahuje obrovský ilustrativní materiál, vrací se k němu i současní lingvisté a ověřují platnost jeho postulátů. Pro tuto práci jsem zvolila srovnávací...

The usage of participles and transgressives of the verbs "buti" (to be), "sakyti (to say) in contemporary texts. Their equivalents in Czech and Latvian languages
Durmanová, Lucie ; Lemeškin, Ilja (advisor) ; Marvan, Jiří (referee)
In my thesis "The usage of participles and transgressives of the verbs "bti" (to be), "sakyti" (to say) in contemporary texts. Their equivalents in Czech and Latvian languages" the object of my research is a grammatical phenomenon of indefinite verb forms in the narrow sense of the Lithuanian, Czech and Latvian languages. The subject matter is a treatise of various forms of participles and transgressives (we are not specifically concerned with infinitive in this thesis), chiefly in the Lithuanian language, but in relation to the Czech and Latvian language. Participles and transgressives are regarded as grammatical units, which are an integral part of a modern-day language; however the currency of their usage, in contrast to the past, is fading. We have focused on a summary of existing knowledge of participles and transgressives in the Lithuanian, Latvian and Czech language, pointing out the similarities and differences among them; on collection of actual language materials and the analysis of the usage in the Bibliographic database of Lithuanian newspaper articles (Lith. Bibliografin Lietuvos periodins spaudos straipsni baz; a collection of articles, published in Lithuanian printed media from 1994 to 2002). One of the objectives of my thesis was to compare equivalents of Lithuanian, Latvian and Czech forms,...

Morphology of ankle fractures - its impact on the type of fracture and the outcomes of treatment
Marvan, Jiří ; Krbec, Martin (advisor) ; Čapek, Lukáš (referee) ; Pilný, Jaroslav (referee)
Ankle fractures can be serious and complex injuries with variable prognoses. In our department, ankle fractures are the third most common fracture behind fractures of the distal radius and the proximal femur. Ankle fractures present with considerable variability with regard to the extent of injury to bones and ligaments, with each injured structure requiring appropriate treatment. We analyzed a group of patients that were surgically treated, in the Orthopedics and Traumatology Clinic, 3rd Medical Faculty of Charles University, for ankle fractures, with a particular focus on the epidemiological, clinical, and morphological parameters of the fractures. Our objective was to supplement existing information regarding the morphology of ankle fractures. Furthermore, we wanted to experimentally verify certain aspects related to ankle fractures. Our first step was to focused on the structure of cortical and cancellous bone in the fibula by carrying out a biomechanical study of the distal fibula after treatment with various types of fixation. The structure of fibular cortical bone was analyzed, using superficial sections, from dry preparations of a human fibula. By rubbing Indian ink into polished sections of cortical bone, we were able to visualize both the direction and organization of the central vascular...

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...
