The article describes some aspects of the activity of the Slovenian liberal magazine “Ljublianski Zvon” in 1899–1914. It was important for the development of Slovenian literature, contributing to the establishment in it of realism and the development of literary criticism. The journal played a major role in acquainting the Slovenian public with Russian culture, primarily with literature.

Otvoritev nove stavbe Deželnega gledališča, ki je luč sveta ugledala v začetku sezone 1892/93, dobrega pol desetletja po uničujočem požaru, je pomenila zgodovinsko prelomnico v slovenski glasbenogledališki poustvarjalnosti. Temeljni kamen operni reprodukciji je slovensko gledališče postavilo sicer že leta 1889, prave pogoje za delo pa je vendarle dobilo šele pod streho novega gledališča, katerega si je delilo skupaj z nemškim vodstvom. Medtem ko so gostujoče nemške družine nadaljevale dolgoletno tradicijo gledaliških predstav, so Slovenci neobremenjeno začeli na samem začetku. Razlika med vodstvi se je pokazala že v prvi sezoni delovanja. Nemci so repertoar prilagajali sposobnostim sezonskih izvajalcev in predvajali največkrat le malo opernih predstav (ali celo nobene), medtem ko so pri oblikovanju sporeda Slovenci dali glavno težo ravno operam. Pričujoče besedilo se osredotoča na prvo dekado delovanja novega Deželnega gledališča. Ločeno sledi najprej nemškemu, nato še slovenskemu glasbenogledališkemu programu. V ospredju zanimanja so operne premiere na eni in drugi strani, pospremljene z odzivi kritik v aktualnih lokalnih časopisih, kot sta Laibacher Zeitung in Ljubljanski zvon. Upoštevajoč tedanje razmere in okoliščine je namen članka podati predvsem strukturni prerez repertoarjev obeh gledališč, ne pa same kvalitete izvedenega, saj so ocene predstav zaradi nacionalnega momenta vprašljivo objektivne in zato med seboj težko primerljive.

The paper is devoted to the language of the Northern Russian lamentations collected and published by E.V. Barsov 150 years ago. The author uses the material of wedding lamentations to study the typical folklore language — composite nominations, i.e. nouns, verbs, and other parts of speech formed on the basis of two (rarely three) lexical units: 1) integral compound words (svet-batiushka, drug-podruzhka, zvon-unylyj), 2) phrases with an application (dusha-devushka, doch’-nevol’nica, idti-shatat’s’a), 3) tautological phrases, i.e. complete or partial reduplications (vol’a-vol’ushka, mesto-mestechko, um-razum, gnevev-gneven) or combinations of synonyms (put’-dorozhen’ka, rod-plem’a, znat’-vedat’, gl’adet’-smotret’, strogo-grozno, zhalko-unylo), 4) constructions with a compositional relationship (gusi-lebedi, zlato-serebro, khleb-sol’, kormit’-poit’, dosyta-dop’ana). The classification is based on the following characteristics: structure (the declination of the components of the phrases), macro-syntax (coordination with both members of the binomial or one of them), micro-syntax (relationship of the components with each other—the subordination or composition) and semantics (whether members of the phrase semantically independent, or one of the members serves as an emotional, evaluative, functional definition, addition, refinement, modification of the other). The specifics of folklore material, and particularly of poetic texts of Northern Russian wedding lamentations, are their structural and syntactic diffuseness, blurring of borders between different types of composite units, the tendency to free syntax of the paratactic type, avoiding explicit means of expressing semantic relations (especially subordinates), the predominance of composition over subordination not only in sentences, but also between components of phrases.

The chemical reduction of nitrate or nitrite species by zero-valent iron nanoparticle (ZVIN) in aqueous solution and related reaction kinetics or mechanisms using fine structure characterization were investigated. Experimentally, ZVIN of this study was prepared by borohydride reduction method at room temperature. The morphology of as-synthesized ZVIN shows that the nearly ball and ultrafine particles ranged of 20–50 nm were observed with FE-SEM analysis. The kinetic model of nitrites or nitrates reductive reaction by ZVIN is proposed as a pseudo-first-order kinetic equation. The nitrite and nitrate removal efficiencies using ZVIN were found 65–83% and 51–68%, respectively, based on three different initial concentrations. By using XRD patterns, the quantitative relationship between nitrite and Fe(III) or Fe(II) becomes similar to the one between nitrate and Fe(III) in the ZVIN study. The possible reason is linked with a faster nitrite reduction by ZVIN. In fact, the occurrence of the relative faster nitrite reductive reaction suggested that the passivation of the ZVIN have a significant contribution to iron corrosion. The XANES spectra show that the nitrites or nitrates reduce to N 2 while oxidizing the ZVIN to Fe 2 O 3 or Fe 3 O 4 electrochemically. It is also very clear that decontamination of nitrate or nitrite species in groundwater via the in-situ remediation with a ZVIN permeable reactive barrier would be environmentally attractive.

The entire circuit was tested on three evangelical church bells in the town Klobouky u Brna.

Kolokol: Spectres of the Russian Bell, submitted by Jason Kaminski in fulfilment of the requirements of PhD (Humanities and Social Sciences) candidature at the University of Technology, Sydney, is an interpretative history of Russian bells (kolokola) and bell music (zvon). As a cultural object and sign, the Russian bell is associated with ideas of transcendence, and ideological and creative ‘vision.’ This interpretation of the signification of the kolokol as a sign arises directly from the perception that the bell is essentially a physical (anthropomorphic) body that is capable of ‘projecting’ or ‘transcending’ itself in the form of a spectrum. This essential ‘spectrality’ defines a history of the Russian bell as an instrument of magical, spiritual and religious ritual, as a cultural artefact associated with changing ideological movements (paganism, Christianity and communism) and as a sign represented synaesthetically in image, sound and text. Ethnographic and campanological studies observe that the kolokol ‘reflects Russian social history like a mirror’, representing the ‘voice of God’ or Logos as an aural or ‘singing’ icon, pointing to the primordial origins of language. This dissertation further investigates the idea that the kolokol acts as an ‘acoustical mirror’ and ‘ideological apparatus’: a medium or spectre through which Russian history and culture is interpellated and reflected. The various logical streams (storytelling, legend, script, text, song, cultural theory, philosophy and ethnography) that contribute to this dissertation form a textual ‘polyphony’ through which the essential meanings and ‘personae’ of the kolokol as a cultural object are interpreted. The bell is regarded as presenting an enigma of signification that must be resolved through investigation and definition. The thesis concludes that the kolokol acts as an iconic sign of the creative ‘Word’ (Logos) and as a symbolic sign that implies a ‘bridge’, copula or psychic ‘hook’, articulating the relationship between the cosmos and consciousness, the material and spiritual, the real and imaginary. Keywords: Russia, Russian History, Russian Arts, Russian Music, Russian Poetry, Russian Political History, Russian Orthodoxy, Russian Revolution, Bell-founding, Bell Music, Bell-ringing, Campanology, Iconology, Kolokol, Zvon.

The diploma thesis is dealing with a topic of hospitality, a natural part of the services sector. Under the conditions of a constant development and ever-increasing competition there is necessary for hospitality industry enterprises to impress upon their customers their unique features and quality. Customers always seek a higher quality of services provided, individualization of services, logically they always look for the highest return of their investments. One of partial aims of this diploma thesis was an analysis of preferences of guests in a context of concept and implementation of a loyalty program. Other partial aim was to analyze indoor and outdoor attributes of the hotel. Marketing and management methods of SWOT analysis, questionnaire etc. have been used to achieve these aims. The main aim of this diploma thesis was to propose an optimal structure of the loyalty program for guests. The program must respect guests{\crq} wishes and needs while remaining financially acceptable for the hotel. A questionnaire has been used to detect the preferences of guests which then formed the basis of proposed loyalty program. Setting the conditions and principles of loyalty program membership was the next step to achieve the main aim. Finally, a detailed calculation of every item and benefit used in the loyalty program was created.

This thesis is about the bells as a culture artefacts. It is divided into four parts. The first part is historica1. It begins with the developement of the bells in the ancient times and continues through the period of the middle ages to the beginning of the bell founding as a craft. It continues with the developement of the bell founding in Bohemia to the present days. The second part treats the technique of the bell manufacturing. It also includes the brief technical description of the bell accessories. The third part treats the bell as a musical instrument and iť s sound. The last fourth part is about legends and stories concerning the bells. This work also mentions well known and famous bells in our country and abroad. The next subject is about orchestral bells which have a little tradition in Czech republic but in the other parts ofthe world is considered as a top ofthe bell founding. The research objective of this work is to show the bell as a multicultural artefact with iť s own history and to describe the bell founding as an original craft. It was very respectful in the past but nowadays it looses iť s importance. One possibility of the future developement in the world are orhcestral bells. Leť shope that this tendence will set up in our country.

Understanding how a therapy will impact the injured kidney before being administered would be an asset to the clinical world. The work in this thesis advances the field of mathematical modeling of the kidneys to aid in this cause. The objectives of this work are threefold: 1) to develop and personalize a model to specific patients in different diseased states, via parameter estimation, in order to test therapeutic trajectories, 2) to use parameter estimation to understand the cause of different kidney diseases, differentiate between potential kidney diseases, and facilitate targeted therapies, and 3) to push forward the understanding of kidney physiology via physiology-based mathematical modeling techniques. To accomplish these objectives, we have developed two models of the kidneys: 1) a broad, steady-state, closed-loop model of the entire kidney with human physiologic parameters, and 2) a detailed, dynamic model of the proximal tubule, an important part of kidney, with rat physiologic parameters. To readily aid physicians, a human model would easily fit into the clinical workflow. Since there is a lack of invasive human renal data for validation and parameter estimation, we employ a minimal modeling approach. However, to aid in deeper understanding of renal function for future applications, targeted therapy testing, and potentially replace invasive measures, we develop a more detailed model. The development of such a model requires invasive data for validation and parameter estimation, and hence we model for rodents, where such invasive data are more readily available. The kidneys are composed of approximately one million functional units known as nephrons. The glomerular filtration rate (GFR) is the rate at which the kidney filters blood at the start of the nephron. This filtration rate is highly regulated via several control mechanisms and needs to be maintained within a small range in order to maintain a proper water and electrolyte balance. Hence, fluctuations of GFR are indicative of overall kidney health. In developing the human kidney model, we also sought to understand the relationship between blood pressure and GFR since many therapies affect blood pressure and subsequently GFR. This model describes steady-state conditions of the entire kidney, including renal autoregulation. Model validation is performed with experimental data from healthy subjects and severely hypertensive patients. The baseline model’s GFR simulation for normotensive and the manually tuned model’s GFR simulation for hypertensive intensive care unit patients had low root mean squared errors (RMSE) of 13.5 mL/min and 5 mL/min, respectively. These values are both lower than the error of 18 mL/min in GFR estimates, reported in previous studies. It has been shown that vascular resistance and renal autoregulation parameters are altered in severely hypertensive stages, and hence, a sensitivity analysis is conducted to investigate how changes in these parameters affect GFR. The results of the sensitivity analysis reinforce the fact that vascular resistance is inversely related to GFR and show that changes to either vascular resistance or renal autoregulation cause a significant change in sodium concentration in the descending limb of Henle. This is an important conclusion as it quantifies the mapping between hypertension parameters and two important kidney states, GFR and sodium urine levels. Glomerulonephritis is one of the two major intra-renal kidney diseases, characterized as a breakdown at the site of the glomerulus that affects GFR and subsequently other portions of the nephron. This disease accounts for 15% of all kidney injuries and one-fourth of end-stage renal disease patients. The human kidney model is used to estimate renal parameters of patients with glomerulonephritis. The model is an implicit system and in developing an optimization algorithm to use for parameter estimation, we modify in a novel way, the Levenberg-Marquardt optimization using the implicit function theorem in order to calculate the Jacobian and Hessian matrices needed. We further adapt the optimization algorithm to work for constrained optimization since our parameter values must be physiologically feasible within a certain range. The parameter estimation method we use is a three-step process: 1) manually adjusting parameters for the hypertension comorbidity, 2) iteratively estimating parameters that vary from person to person using no-kidney- injury (NKI) data, and 3) iteratively estimating parameters that are affected by glomerulonephritis using labeled diseased data. Such a process generates a model that is personalized to each given patient. This patient-specific model can then be used to simulate and evaluate outcomes of potential therapies (e.g., vasodilators) on the model in lieu of the patient, and observe how alterations in blood pressure or sodium level affect renal function. Parameter estimation in the presence of glomerulonephritis is a challenging task due to the complexity of the kidney physiology and the number of parameters to estimate. This is further complicated by comorbidities such as hypertension, cardiac arrythmia, and valvular disease, because they alter kidney physiology and hence, increase the number of parameters to estimate. We chose to focus on hypertension since it is very prevalent in hospitals and intensive care units. It was found that over all patients, average model estimates of GFR and urine output rate (UO) were within 9.2 mL/min and 0.71 mL/min for NKI data. These results are expectedly better than those achieved from the non-personalized model since the parameters are now specific to each patient. The results also demonstrate our ability to non-invasively estimate GFR with less error than the 18 mL/min currently possible. The estimations were validated by ensuring that the estimated parameter values were physiologically sound and matched the literature in terms of expected values for different demographic groups. It is vital for a properly functioning kidney to maintain solute transport throughout the nephron. Kidney diseases in the nephron can manifest themselves via the solute transport mechanisms. To understand how these diseases affect the kidney and to simulate transporter- targeting therapies, we have developed a detailed model, starting from the human model previously developed, of one portion of the kidneys, the proximal tubule. The proximal tubule is the site of the most active transport within the nephron and the target for several therapies. Our goal is to study and understand the dynamic behavior of the proximal tubule when solute transporters breakdown and to investigate treatment therapies targeting certain solute transporters. The proposed model is dynamic and includes several solutes’ transport mechanisms, with parameters for rats. We chose to investigate diabetic nephropathy and the associated sodium-transporter alteration (knockout) therapy. Diabetic nephropathy is characterized as kidney damage due to diabetes and affects 30% of diabetics. In terms of reducing hyperfiltration, a potential cause of diabetic nephropathy where an overabundance of solutes and fluid are filtered at the glomerulus, the model demonstrates that knockout of this transporter results in a reduction in sodium and chloride reabsorptions in the proximal tubule, thereby preventing hyperfiltration. Further, we conclude that vital flows for maintaining kidney homeostasis, fluid and ammonium reabsorptions, are corrected to healthy values by a 50% knockout (impairment) of the sodium-hydrogen transporter. Next, we use the dynamic model to detect different diseased states of the proximal tubule transporters. We have accomplished this task by using Bayesian estimation to estimate transporter density parameters (a metric for kidney health) using measured signals from the proximal tubule. This approach is validated with experimental rat data, while further investigations are conducted into the performance of the estimation in the presence of varied input signals, signal resolutions, and noise levels. Estimation accuracy within 20% of true transporter density and within 4% of true fluid and solute reabsorption was achieved for all combinations of diseased transporters. We concluded that including chloride and bicarbonate concentrations improved estimation accuracy, whereas including formic acid did not. This is an important conclusion as it can help physicians determine which blood tests to order for diagnosing kidney disease; to our knowledge, this is a first. It was also found that sodium and glucose proximal tubule concentrations are most affected by changes in the sodium-hydrogen and sodium-bicarbonate transporters. This conclusion provides insight into the interplay between solute transporter density and sodium and glucose concentrations in the proximal tubule. Such knowledge paves the way for new transporter targeted therapies.

The publication "Stories of Hidden Art" discusses an little known sector of medieval art in Czech countries - decoration of bells. The most important aim of this book is to introduce this unusual and interesting topic to experts as well as the public. Using facts derived from research, this thesis is presented in essay form including pictures allowing the text to be easily read and understood. The topic is discussed in nine chapters, each of them with a story "told by the bell". The reader will gain a step-by-step understanding of the reasons and functions of the bell, its evolution, decoration and wider social-historical facts that mirror the bell's appearance. A large focus is put into international and interfield relationships; in case of the most expanded set of Czech bells' reliefs we can follow its origin back to its creation in the Austrian Judenburg, where we can also find many parallels in contemporary statuary and painting. Similar continuity is to be found comparing other reliefs, often of a very good quality, which can be a valuable method of challenging existing beliefs that the handcrafted arts are inferior to so called "high" art.

The thesis deals with conception of baptism by utraquist priest Jan Bechyňka. At first the figure of the peculiar writer and theologian after being introduced is integrated into historical connections of the jagellonian era. The chapters that follow aim at the particular topic. Bechyňka ́s view of pedobaptism drawn from a long passage about commitment of baptism from his Traktát o viděních a pokušeních zbožného mládence [The Tractate on Visions and Temptations of Devout Youth] is compared with pedobaptism in Chelčický ́s Zprávy o svátostech [Reports of Sacraments] and with baptism in general of another Chečický ́s work - Rozpravy [Disccusions] in Parisian manuscript. At first I had intended finding out paralles between mentioned thinkers, however certain differences have appeared as well, not in essential facts. In the case of Bechyňka ́s tractate O křtu zvonu [On Baptism of the Bell] I give an interpretation to it in the concrete. The last chapter deals with utraquist baptismal praxis in the early modern times and in the present day and in general describes baptismal rites of these times. As a apendix I add Bechyňka ́s tractate O křtu zvonu [On Baptism of the Bell] with a commentary and transcriptional notes. Powered by TCPDF (www.tcpdf.org)
