Abstract:
Most of the onomastic units mentioned in the written monuments of ancient times are valuable sources in terms of studying the past, language, lifestyle, ethnogenesis, ethnography of our people today. While these monuments are important in terms of clarifying historical realities and shedding light on obscure issues, on the other hand, their study is politically important in modern times. At a time when our hated neighbors are looking at our lands and making historical distortions, the study of onomastic units in ancient monuments – toponyms, anthroponyms, oronyms, hydronyms, etc. – can be a convincing answer to baseless fabrications. It should be noted that we come across information and explanations about each of these hydronyms in scientific and historical sources written from ancient times to the present day, and the core of each of them is of Azerbaijani-Turkish origin. The monument involved in the study names countless water bodies associated with the territory of Azerbaijan. They are also very valuable in terms of studying the lexical and semantic development of our language. We come across information and explanations about each of these hydronyms in scientific and historical sources written from ancient times to the present day. One of the hydronyms directly connected with the territory of Azerbaijan in the source is the Caspian Sea. Books and articles about the Caspian Sea give it different names and etymological-linguistic analysis of the word Caspian. Another hydronym mentioned in the source is Tartar river. The article provides extensive information about the Tartar River in terms of its geographical structure. The hydronym Tartar is given in Arabic, Russian, Georgian and ancient Turkic sources with different phonetic structure. The name of the Urdun River is mentioned several times in the source. However, it should be noted that the Urdun River flows not in the Albanian country, but in the Middle East, and most of it flows in the territory of modern Jordan. Although the explanation of some of the hydronyms included in the ancient Caucasian Albanian territory in the source is convincing, the exact explanation of many ancient hydronyms still remains controversial. One example of such controversial hydronyms is the Urdun River. The last hydronym mentioned in the article is Goycha river. Extensive geographical, historical, etymological interpretations and linguistic analysis of the hydronym are given. Key words: river, morphemes, geographical names, modern areal, hydronyms, onomastic

Abstract:
The paper deals with the verification of several etymological versions, suggested for interpretation of hydronyms (i.e. names of water geographical objects) of ancient Slovakia. Earlier these lexical units were classified as elements of Iranian (Sarmatian and Alanian) substratum in local Slavic historical toponymy. The author compares etymological versions, existing in scientific circulation, and finds out the soft spots in their argumentation and also notes the lack of proof for different contentions. The special attention is given to problematic question of ambiguity of orthography of documented forms hydronyms, because ambiguity all too often gives grounds for several (absolutely different) interpretations of one word. Consequently, here is focused on the problem of choice of a certain variant as more «authoritative» (i. e. maximally closed to primordial, etymological form) for research. Critical assessment of proposed above etymological versions uncovers new resources for genetic interpretation of five viewed hydronyms, which can be surely defined as Celt and Germanic lexical heritage in Slovak hydronymy. Among river names the primordial Germanic hydronym is pointed out; one is extended with Middle Iranian term of geographical nomenclature, which evidences about lexical reception of Germanic toponymy stratum traces in the speech practice of Sarmatian and Alanian population and consequently about both ethnoses lingual interaction. In particular Celtic and Germanic etymologies are suggested for such Slovakian hydronyms: Hasztergan, Hor. Hastrgan, Hor. Hastrgan = *Gaster-gan < Germ. *Gaster ‘stream in ravine’, extended with Iran. *kan ‘sorce, well, spring’; Kubra, Cubra = Celt. *kubr (< adj. *kumb-ro-) ‘stream, current on valley’; Metrbos = Germ. *Mittel-bach, *Mittel Bach or *Mitlpos(sky) ‘between creeks’; Nuduna = Celt. *nau-dun ‘port for boats’, ‘fortification with marina for boats’; Gardubarto, Gardubartu, Karduberka, Chaduwocha = Celt. *kar[r]-dubur = «stone water», «stone stream» + Hung. to [tava, tavat] ‘lake’, ‘pond’.

Abstract:
The article discusses the history of the hydronyms Shchugor, Patok, Glubnik, Torgovaya, Volokovka, Pyatidyrka, and Semidyrka, i.e. the names of the Shchugor River and its several tributaries of the first and second orders. Presently, these names mostly have a “Russian” phonetic appearance, however, their historical variants suggest that some of them may be a result of semantic adaptation of pre-Russian names. The authors suggest that the hydronyms Pyatidyrka and Semidyrka originated from Nenets names with a composite determinant -dyrma, expressing recurrence and place of action. In other examples, there is a parallel coexistence of several similar versions of one hydronym belonging to different languages, cf.: Russian Torgovaya, Komi-Zyryan Törgövöy-yu, Nenets Menyaylava. This can be regarded as a testimony to the past and current contacts of the Russian population with indigenous peoples — speakers of Finno-Ugric and Samoyedic languages. In some cases, the older pre-Russian form of a hydronym might be missing, i.e. replaced by a Russian-language variant without any trace of the substrate name. For example, the Komi-Zyryan hydronym Pyzhenyuts (from Komi-Zyryan pyzh ‘boat,’ literally “River on which boats can sail”) was replaced in the Old Russian period by the name Padun and, later, by the name Patok, both of the latter hydronyms being originally Russian. The article also analyzes native Russian names for which the most probable motivation can be established based on geographic data. Incidentally, the traditional interpretation of the name of the river Glubnik as “deep river” or “river with deep places” is called into question, since such an interpretation does not correspond to physical and geographical features of the river, the authors interpret the name as “River flowing from the depths of the taiga.” All linguistic observations and etymological interpretations of hydronyms presented in the article are based on the analysis of a large array of cartographic sources of the 16th–20th centuries; finally examples are given of the distortion of the spelling of the hydronyms of the Shchugorsk area of the Urals on the maps of various times.

Abstract:
The article examines the substrate hydronymy of the middle Oka and the Dnieper regions (ending in -va, -da, etc.) that is typically attributed to the West-Baltic toponymic stratum and associated with the language of the Moschinskaya archaeological culture and the related archaeological sites. The author analyzed its spatial distribution in the East European Plain. The study has found that: 1) the spread of names of waterbodies ending in -va correlates with the distribution scheme of substrate Baltic hydronymy in general and the monuments of the Dnieper-Dvina, Yukhnovskaya, and Late Dyakovo cultures of the Early Iron Age; 2) the spread of hydronyms with zh/z sound variation (including as a distinctive feature) correlates with the Krivich and Radimich culture areas, and the range of Russian dialects with lisping pronunciation which makes no difference between sibilants and hushing sounds; 3) Baltic hydronymy ending in -da is not attested in the area of the Moschinskaya culture and related archaeological sites; 4) among the names with the root ape-/upe- found in the same cultural milieu, only those containing Eastern Baltic variant are verifiable; 5) the hypothesis for East Baltic origination of the names with the root stab- is not inferior to the West Baltic; 6) there are no sufficient grounds for tracing some river names to the Prussian words pannean and sug since most of these hydronyms refer to a later period while the others have more plausible explanations; 7) for some hydronyms (Zerna, Opochinka, Ponya, Sezhikovka, etc.) the substrate origin is not confirmed. Based on the above observations, the hypothesis for the presence of a West-Baltic layer of hydronymy in the middle Oka region and the consequent assumption of the West-Baltic origin of the Moshinskaya culture were disputed.

Abstract:
The article is a study of the origin of Bashkir hydronyms with anlaut L-, (Labau, Lämäz, and a number of others). Against the background of extensive comparisons of similar hydronyms and appellatives from the Turkic, Altaic, and other Eurasian languages. The author considers several versions of the said hydronyms viz possible origin from the Turkic, Altaic, Uralic or Euroasiatic languages at large. The stem and/or root of Bashkir hydronyms of the Lämäz type may be cognate with such hydronims as Laba in Poland > the Elbe in East Germany, -lej ‘a small river’ in the Volga Finnie languages and with a fair number of similar names of water objects in Europe, Asia and beyond. So, convergence with many of the same-root names of water bodies from several dozen languages and/or dialects is proposed. A large amount of material from the dialects and subdialects of the Bashkir language is involved. A conclusion is proposed about the very great antiquity of the hydronyms containing the anlaut L- in the bases of the LVC phonomorphological type. The answer to the question posed in the article’s title can hardly be definitive, as much further research is needed to clarify many points.

Abstract:
The article is devoted to the analysis of the Dnieper water bodies nominations on the territory of the Smolensk region. The research is aimed at consideration of the most important onomastic problem at present – variation in the sphere of the proper names, particularly in the hydronymy. Amidst the regional onomastic development, the research in the sphere of toponymy and hydronymy is being actively carried out, toponymic dictionaries are being published. In these dictionaries the variants of the geographical objects are often only marked down. However, more focused attention to the revealing and describing the reasons and methods of their variation allows the researchers to carry out more detailed diachronic analysis of the onyms existence in the different historical periods and define the invariants formation. The most interesting field of research is the toponymy and hydronymy study of the Smolensk region – western border region of Russia. The material of the research is based on the military-topographical map of Smolensk Governorate, large scale maps and an atlas of the Smolensk region, as well as written information sources. The author has analyzed the examples of the orthographical, phonetical, morphological and lexical variants of hydronyms and has tried to reveal the linguistic and extralinguistic reasons of the water bodies nominations variation in this region. It is proved that the hydronyms variants origin is typical for small water currents; it is linked with their shallowing and the loss of their significance in the economic life of the population. The predominance of the phonetical variants is explained by the influence of the general-linguistic process, a local dialect lect, a living colloquial language. The variation on the word formation level is widely represented by diminutive forms as a result of the changes in the water currents physico-geographical parameters. Lexical variation of the hydronyms in the region depends on the nominations de-etymologisation. Moreover, in the analyzed region the author has found out a lot of variants of hydronyms with changes at different language levels. Linguistic and extralinguistic reasons of variation in hydronymy are closely linked. This fact can make it more difficult to determine the method of the new variant creation. The analyzed factual material will be practically used in the «Hydronym’s Dictionary of the Smolensk Region», which will be published soon.

Abstract:
In their article devoted to hydronyms in the oral and handwritten charms of the North Russian, T. A. Agapkina, E. L. Berezovich, and O. D. Surikova comment on the name of a fiery river Apolevta assuming that there may exist two copies of the text. The authors suggest that this river name might either originate from an unestablished Greek word or else, is a case of erroneous usage. The author of the present work argues the existence of one single copy of the text that was published by N. N. Vinogradov in 1910. As regards the hydronym Apolevta, the structure of the original text (particularly, the space organization) testifies to an incorrect interpretation by the scribe: in fact, the text uses a short form of the adjective with a postpositive particle -to which frequently occurs in North Russian dialects. Thus, the hydronym Apolevta is a result of an incorrect reading of the source by V. A. Ivanovsky.

Abstract:
The mass spectral peak observed at 19 amu in residual gas analyzers at very high (<10-6 Torr) and ultrahigh vacuum (<10 -9 Torr) has often been attributed to fluorine. Using Fourier Transform Mass Spectrometry, the hydronium ion, H3O+, has been fully resolved from F+ and its correlation to water vapor concentration was determined to be linear as expected for a gas phase process. The comparison of the mass 19 signals for a conventional quadrupole mass spectrometer and a Fourier transform mass spectrometer on the same vacuum chamber indicated hydronium was the source of mass 19.;The partial pressures of H2O in the very high vacuum range and higher suggest there is sufficient H2O density for the hydronium ions to form through ion-molecule interactions because hydronium formation was found to directly correlate with the H2O partial pressure. However, in a QMS at UHV, formation of H3O+ appears to occur principally by electron stimulated desorption (ESD). Introducing hydrogen into the system from 1 Langmuir exposure to saturation (1 x 10-6 Torr for 8 hours) increased the H3O + ESD yield detected by the QMS by as much as a factor of 10. The initial hydronium ESD cross section from a hydrogen saturated grid was estimated to be sigma ∼ 1 x 10-19, cm2.;TOF-SIMS sputter yields from the stainless steel grid of a quadrupole mass spectrometer also showed small signals of H3O+, as well as its constituents (H+, O+ and OH) and a small amount of fluorine as F-, but no F+ or F+ complexes (HF+, etc.). Using x-ray photoelectron spectroscopy, a small amount (0.4%) of fluorine was found in the surface of stainless steel. Electron bombardment reduces the fluorine bound in surface complexes, but not metal halides found below the surface. However, heating the sample eliminated the F 1s signal entirely, indicating that fluorine is not likely to be the source of mass 19 in residual gas analysis. Also, changes in the spectral shoulders on the O 1s and Cr 2P3/2 peaks show that hydrogen dosing stainless steel and chromium increases the amount of hydroxides at the surface, while heating and electron bombardment reduce them.

Abstract:
When analysing the etymological layers of Hungarian river names, it becomes soon clear that loan names make up a much larger group than in the group of settlement names, for instance. This fact can be due to the phenomenon that in the case of hydronyms, name-giving and name-usage is driven mainly by communicative needs, while other (e. g. socio-cultural or political) factors only rarely influence name-giving. In my paper, it was my aim to provide an etymological typology of Hungarian hydronyms from the Árpád-era (896 –1350). It seems to be justified to choose the Hungarian hydronyms of the Árpád-era as the corpus of my investigation, for the country was strongly multilingual and multiethnic in this period of time (Hungarian, Slavic, German, Turkish), which also has an effect on the system of water names. The survey of the linguistic layers of river names shows that largely the same semantic content appears in river names originating from different languages. The semantic types appearing in river names belong to the so-called panchronistic feature of the hydronym system, in other words, they show signs of universal human thinking.

Abstract:
Enhancing the heat output of the hydronic central heating system in buildings can play a major role in reducing energy consumption and CO2 emission. The main aim of this PhD research is to investigate the effect of pulsed flow input on the energy consumption of panel radiators in hydronic central heating systems and the user indoor comfort defined by ASHRAE standard 55 and EN ISO 7730. The research covers thermal performance of panel radiator and the indoor comfort. The work was performed using dynamic control modelling, CFD and experimental testing to prove the concept. Results from the mathematical and CFD modelling of the hydronic radiator with pulsed flow using various frequencies and amplitudes showed that 20% to 27% of energy saving can be achieved compared to the constant flow while maintaining the same radiator target surface temperature of 50oC as recommended by the BS EN442. The indoor comfort results were also achieved as recommended by international standards including CO2 concentration at 1000PPM±50PPM, relative humidity at 50±9%, comfort temperature at 20±1.6oC, air velocity of below 0.15m/s and draught risk parameters of less than 15%. The numerical results agreed well with experimental results with maximum deviation of radiator temperature output of ±4.1%, indoor temperature ±2.83% and energy saving of ±1.7%. The energy saved due to the pulsed flow is attributed to the enhancement of the radiator heat transfer performance that leads to higher heat output at lower average mass flow rate of the hot water.

Abstract:
Doutoramento em Biologia
Os estuários são ambientes complexos, biologicamente diversos e muito importantes no que respeita à produtividade primária. As zonas intertidais destes ecossistemas são ocupadas por organismos que possuem uma elevada capacidade de sobrevivência e adaptação face às variadas e rápidas alterações nos factores ambientais (tais como temperatura, salinidade, conteúdo hídrico, etc.). As cadeias tróficas com origem no ecossistema estuarino bentónico são essencialmente herbívoras, regulando o fluxo de energia desde o fundo sedimentar e através do ecossistema. Nas áreas estuarinas intertidais a produção primária é essencialmente suportada pelo microfitobentos (MPB). Estas comunidades de microalgas bênticas constituem uma importante fonte de matéria orgânica e são por si só a principal fonte alimentar para as populações de Hydrobia. Neste contexto, a interacção MPB - Hydrobia é um modelo-chave na investigação da cadeia trófica estuarina de origem bentónica, actuando como um importante canal de transporte de energia para os níveis tróficos superiores, especialmente se considerarmos que Hydrobia é uma importante presa para peixes, aves e caranguejos. O presente estudo tem por objectivos gerais: i) a investigação do controlo ambiental (particularmente da luz e do teor em água do sedimento) e endógeno na migração vertical do MPB e ii) a identificação e potencial utilização de marcadores tróficos (pigmentos e ácidos gordos) úteis à investigação da interacção MPB – Hydrobia em laboratório e em condições naturais, considerando a existência de uma elevada plasticidade trófica por parte da Hydrobia e a elevada densidade populacional que estes organismos podem apresentar. A primeira fase de investigação resultou na comparação do papel dos estímulos ambientais e do controlo endógeno nos padrões de comportamento migratório vertical do microfitobentos, demonstrando a existência de um controlo essencialmente endógeno na formação e desintegração do biofilme superficial. A regulação e manutenção da biomassa à superfície do sedimento são claramente controladas pela variação dos factores ambientais, em especial da luz, cuja presença é essencial à formação total do biofilme microalgal à superfície do sedimento intertidal. Foi proposta uma nova abordagem metodológica com vista à estimativa nãodestrutiva do teor de água de sedimentos intertidais vasosos , possibilitando o estudo da influência da acção do vento no conteúdo hídrico dos sedimentos e o consequente impacto da dessecação na comunidade microfitobêntica. Observou-se que a dessecação provoca efeitos limitantes não só na biomassa superficial mas também na actividade fotossintética dos biofilmes microfitobênticos, conduzindo à diminuição da produtividade primária. No que respeita à dinâmica trófica da interacção MPB - Hydrobia foi estabelecido o uso do pigmento feoforbide a, quantificado nas partículas fecais da fauna, como marcador trófico que permite estimar a quantidade de biomassa de microalgas (clorofila a) incorporada pelos organismos animais.Para tal foi investigada e comprovada a existência de uma relação significativa entre a concentração de feopigmentos excretados e a concentração de clorofila a ingerida. Estes estudos foram desenvolvidos numa primeira fase à escala diária, considerando os efeitos dos ciclos sazonais, dia-noite e maré, e depois com a validação em condições naturais, numa escala mensal. A taxa de ingestão média de indivíduos de H. ulvae varia ao longo do dia, com o máximo em torno dos períodos diurnos de maré baixa, o que pode estar relacionado com a disponibilidade de MPB. As taxas de ingestão (TI) de H. ulvae variam ainda em função da estação do ano (TI verão > TI primavera) e em função da densidade de indivíduos (> densidade, < ingestão). Verificou-se um efeito negativo na concentração de clorofila disponível após herbívoria independentemente da densidade de indivíduos. Finalmente, a comparação dos perfis de ácidos gordos de H. ulvae provenientes de diferentes habitats com os perfis de potenciais fontes alimentares permitiu demonstrar que os ácidos gordos são ferramentas úteis na identificação do habitat ocupado por estes organismos. No entanto, apesar da ocupação de diferentes habitats e da integração de múltiplas fontes de produção primária na sua dieta foram sempre observados significativos níveis de ácidos gordos específicos de microalgas (em particular diatomáceas), reforçando o papel importante das comunidades de microalgas bênticas na dieta das populações de H. ulvae.
Estuaries are biologically diverse and form complex environments, which play an important role on the global primary productivity of aquatic environments. Intertidal areas of estuaries are inhabited by organisms with a strikingly capability to survive and to be adapted to frequent and fast changes in several environmental factors (such as temperature, salinity, water content, etc.). Grazing food chains are common in intertidal mudflats regulating the flow of nutrients and energy from the bottom throughout the estuarine ecosystem. Within intertidal estuarine areas the primary production was predominantly supported by microphytobenthos (MPB). These benthic microalgae assemblages are an important source of organic matter and are a main food source for Hydrobia populations. The MPB - Hydrobia interaction is a key model for the estuarine grazing food chain, acting as a significantly channel of energy to higher trophic levels, since Hydrobia is an important prey item for fish, birds and crabs. The present work addressed: i) the environmental (namely light and sediment water content) and the endogenous control of the vertical migration by microphytobenthos, and ii) the identification and the potential use of trophic markers (pigments and fatty acids) to establish this relationship under laboratory and natural conditions, considering that H. ulvae showed significant trophic plasticity and that mud snails could reach extremely high densities. The role of exogenous cues and endogenous control of the patterns of vertical migratory behavior of intertidal MPB biofilms were compared, showing that the formation and disintegration of the biofilm is endogenously-controlled. The regulation and maintenance of the microalgal biomass at the sediment surface is dependent on the variation of environmental factors, namely light, which is essential for the full formation of the MPB biofilm. A new methodological approach was proposed to estimate the water content of muddy intertidal sediments, enabling the study of the influence of wind on the hydric level of the sediment and the consequent impact of desiccation on the MPB biomass. This investigation showed that desiccation might be responsible to cause important limiting effects on biomass and photosynthetic activity of intertidal MPB biofilms, reducing the primary productivity. Regarding the trophic dynamics of the interaction MPB - Hydrobia, it was established the use of the pigment pheophorbide a, present on Hydrobia ulvae faecal pellets, as a trophic marker to estimate the amount of microalgal biomass incorporated, as chlorophyll a, by benthic macrofauna. A significant relationship between egested pheopigments and ingested chlorophyll a was investigated and validated. These studies were firstly developed on a daily scale, considering the effects of seasonal, tidal and day-night cycles, followed by a validation under natural conditions, on a monthly scale. The mean ingestion rate of H. ulvae individuals varied along the day, with the maximum around the diurnal low tide periods, which may be related with MPB availability. H. ulvae mean ingestion rate (IR) also varies seasonally (IR summer > IR spring) and depending on mud snails density (> density, < ingestion). There was a negative effect on chlorophyll concentration available after grazing, independently of H. ulvae density. Finally, the comparison of fatty acid profiles of mud snails from different habitats with the ones from potential food sources allowed identifying fatty acids as a useful tool to indicate H. ulvae habitat. Although the occupation of different habitats and the integration of multiple primary food sources on mud snails diet, significant inputs of fatty acids specific of microalgae (namely diatoms) were always found, which reinforce the important role of MPB on the diet of H. ulvae populations.

Abstract:
Hydronic solar systems with copper tube collectors or vacuum glass tube collectors are commonly used thermal-solar systems. These systems run well in residential buildings or in small scales for domestic water heating. These systems can be scaled up and applied to commercial buildings. The solar energy collected by these systems can be used to drive absorption chillers in summer and heat the feed water for boiler in winter. Properly designed and installed systems can save energy by utilizing free solar energy. However, operation and maintenance do have an important impact on whether these systems truly save energy. This paper presents a technical review of a large scale hydronic solar system installed in Carbondale, Illinois and compares this system with a photovoltaic system which was proposed to retrofit the hydronic solar system in energy conversion efficiency, system components, initial cost, operation and maintenance etc.

Abstract:
Energy requirements for heating and cooling of residential, commercial and industrial spaces constitute a major fraction of end use energy consumed. Centralized systems such as hydronic networks are becoming increasingly popular to meet those requirements. Energy efficient operation of such systems requires intelligent energy management strategies, which necessitates an understanding of the complex dynamical interactions among its components from a mathematical and physical perspective. In this work, concepts from linear graph theory are applied to model complex hydronic networks. Further, time-scale decomposition techniques have been employed to obtain a more succinct representation of the overall system dynamics. Lastly, the usefulness of the proposed model for energy efficient operation of the system through advanced control techniques has been discussed.

Abstract:
Polymer electrolyte fuel cells (PEFCs) are highly expected as a next-generation power supply system due to the purity of its exhaust gas, its high power density and high efficiency. The polymer electrolyte membrane is a critical component for the performance of the PEFCs and it is important to understand the nanostructure in the membrane to enhance proton transport. We have performed an atomistic analysis of the vehicular transport of hydronium ions and water molecules in the nanostructure of hydrated Nafion membrane by systematically changing the hydration level which provides insights into a connection between the nanoscopic and mesoscopic structure of ion clusters and the dynamics of hydronium ions and water molecules in the hydrated Nafion membrane. In this study, classical molecular dynamics simulations are implemented using a model of Nafion membrane which is based on DREIDING force field and newly modified and validated by comparing the density, water diffusivity, and Nafion morphology with experimental data. The simulated final density after the annealing procedure agrees with experiment within 1.3 % for various water contents and the trends that density decreases with increasing hydration level are reproduced. In addition to determination of diffusion coefficients of solvent molecules as a function of hydration level (from λ = 1 up to λ = 18), we have also calculated radial distribution functions and static structure factors not only to clarify the structure of water molecules and hydronium ions around the first solvation shell of sulfonate groups but also to validate the mesoscopic periodic structure among water clusters. The diffusion coefficient of water molecules increases with increasing hydration level and is found to be in good agreement with experimental data. The diffusion coefficient of hydronium ions has showed that general trends in the experimental data are reproduced by the simulations although the classical models have the limitation of probing hydronium dynamics. The static structure factors of liquid molecules at low wave length provide insights into the periodic structure of the inter-water clusters. These results are consistent with the Gebel’s model based on small-angle X-ray scattering that considers the dry membrane to be made of isolated spherical ionic clusters of radius ∼7.5 Å that swell with increasing hydration.
