Abstract:

The name of the river Lambro/Lambrus near Milano (Italy/Roman province Gallia-Transpadana) will be reconstructed as indoeuropean *h1lṇgwhró-s ‘quick’. Compared with other geographic names it will be supposed, that Lambrus is a celtic relict name. The problem is, in which way celtic labiovelars, e.g. /gw/, are integrated in the post-celtic languages.

Abstract:

This thesis resolved the structural ambiguity surrounding ammonium and hydronium ions in the jarosite mineral group. The vibrational spectra of these two minerals were rationalised with their crystal structures for the first time. In doing so, a theory for dealing with orientational disorder in crystals was proposed.

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 pres

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 Árp

Until now, a phenomenon such as this had never been formally quantified.

In particular, the thermal energy used in rooms can be expressed as the efficiencies for emission in a space heating system. This thesis analyzes the efficiencies for emission of a space heati

The marine hydroid Garveia annulata is a small, brightly colored coelenterate whose crude methanol extracts exhibit potent antibacterial and antifungal activity.

Twenty one metabolites have been isolated and their structures were elucidated by using a combination of spectral analysis, chemical interconversions, synthesis and single crystal X-ray diffraction analysis.

Abstract:

In countries with harsh winter climates extensive winter road maintenance is necessary to achieve traffic accessibility and road safety. These measures have high economic and environmental costs as snow free roads and winter road maintenance in Sweden today is achieved by a combination of mechanical snow clearance and the spreading of salt to prevent ice formation. The salt ends up in the roadside environment and has negative effects on groundwater and vegetation. An alternative to traditional winter road maintenance to obtain non-skid winter roads is the use of hydronic pavement(HP) systems.

There are many questions associated with the understanding of the origin and regulation of bioluminescence. A key question underlying this thesis was why coelenterazine evolved as the most common marine luciferin. Another problem addressed was the coelenterazine source of the bioluminescent hydroid Obelia, which is unknown. Coelenterazine is an integral part of Obelia’s photoprotein, triggered by Ca2+. The thesis also investigated the uncertainty over how Ca2+ enters Obelia’s photocytes. Obelia is considered to have four species, but they have been misidentified. Green fluorescent protein (GFP

In the late 1990s a unique technique for quantification of organic trace gas species, proton transfer reaction mass spectrometry (PTR-MS) was developed.

Dans l'objectif d'analyser la dynamique du flux trophique entre le microphytobenthos et le gastéropode Hydrobia ulvae nous avons caractérisé la dynamique et la structure des compartiments étudiés, puis quantifié expérimentalement l'effet de ces facteurs, ainsi que celui des principales variables environnementales, sur le taux d'ingestion de H. Ulvae. La biomasse microphytobenthique oscille entre 40 et 150 mg Chl a m-2 à l'échelle saisonnière. La communauté microalgale se caractérise par la dominance de petites espèces. L'étude de la dynamique de population de H. Ulvae a montré l'influence de m

Abstract:

Industrial and military vehicles, including trucks, tanks and others, employ cooling systems that address passenger cooling and auxiliary cooling loads ranging from a few Watts to 50 kW or more. Such systems are typically powered using vapor-compression cooling systems that either directly supply cold air to the various locations, or cool an intermediate single-phase coolant closed loop, which in turn serves as the coolant for the passenger cabins and auxiliary loads such as electronics modules. Efforts are underway to enhance the performance of such systems, and also to develop more light we

Abstract:

This master’s thesis deals with heating and HVAC in production plant ELMET, spol. s r.o. The first part of the thesis concerns reconstruction of the central heating system, which is outdated and unreliable in the time of the writing of the thesis. The second part deals with cooling of mounting of electronics, where technological requirements are not met due to summer overheating. The third part of the thesis concerns ventilation of metalworking hall using waste heat from production machines.

Abstract:

Understanding the implications of climate change on streamflow regime is complex as changes in climate vary over space and time. However, a better understanding of the impact of climate change is required for identifying how stream ecosystems vulnerable to these changes, and ultimately to guide the development of robust strategies for reducing risk in the face of changing climatic conditions. Here I used physically based hydrologic modeling to improve understanding of how climate change may impact streamflow regimes and advance some of the cyberinfrastructure and GIS methodologies that support

Abstract:

This thesis presents a novel distributed control method which allows a collection of independently mobile robotic units, with two or three dimensional movement, to self-assemble into self-repairing hierarchical structures. The proposed method utilises a simple model of the cellular adhesion mechanisms observed in biological cells, allowing the robotic units to form virtually bonded aggregates which behave as predicted by Steinberg’s differential adhesion hypothesis. Simulated robotic units based on the design of the subaquatic HYDRON module are introduced as a possible platform on which the mo

Abstract:

Neste trabalho, foram efetuados estudos sobre o comportamento eletroforético dos íons hidrônio (H3O+) e hidroxila (OH-) utilizando eletroforese capilar em zona em meio não-tamponado e detecção condutométrica sem contato. Alterações na composição do eletrólito de corrida devido à eletrólise foram evitadas empregando um sistema de eletrólise separada. A determinação de ácidos com pKas menores ou iguais ao pH do eletrólito de corrida foi possível. A possibilidade da análise em bases fortes também foi demonstrada. Eletrólitos de corrida com pH entre 4,5 e 7,0 (para o H3O+) e entre 7,0 e 9,0 (para
