description: In 1978, Dhar suggested a model of a lattice gas whose states are partial orders. In this context he raised the question of determining the number of partial orders with a fixed number of comparable pairs. Dhar conjectured that in order to find a good approximation to this number, it should suffice to enumerate families of layer posets. In this paper we prove this conjecture and thereby prepare the ground for a complete answer to the question.

description: We give a new proof for a Ray-Knight representation of Feller's branching diffusion with logistic growth in terms of the local times of a reflected Brownian motion $H$ with a drift that is affine linear in the local time accumulated by $H$ at its current level. In \cite{LPW}, such a representation was obtained by an approximation through Harris paths that code the genealogies of particle systems. The present proof is purely in terms of stochastic analysis, and is inspired by previous work of Norris, Rogers and Williams \cite{NRW}.

description: The stellar kinematics of the spheroids and discs of S0 galaxies contain clues to their formation histories. Unfortunately, it is difficult to disentangle the two components and to recover their stellar kinematics in the faint outer parts of the galaxies using conventional absorption line spectroscopy. This paper therefore presents the stellar kinematics of six S0 galaxies derived from observations of planetary nebulae (PNe), obtained using the Planetary Nebula Spectrograph. To separate the kinematics of the two components, we use a maximum-likelihood method that combines the discrete kinematic data with a photometric component decomposition. The results of this analysis reveal that: the discs of S0 galaxies are rotationally supported; however, the amount of random motion in these discs is systematically higher than in comparable spiral galaxies; and the S0s lie around one magnitude below the Tully--Fisher relation for spiral galaxies, while their spheroids lie nearly one magnitude above the Faber--Jackson relation for ellipticals. All of these findings are consistent with a scenario in which spirals are converted into S0s through a process of mild harassment or "pestering," with their discs somewhat heated and their spheroid somewhat enhanced by the conversion process. In such a scenario, one might expect the properties of S0s to depend on environment. We do not see such an effect in this fairly small sample, although any differences would be diluted by the fact that the current location does not necessarily reflect the environment in which the transformation occurred. Similar observations of larger samples probing a broader range of environments, coupled with more detailed modelling of the transformation process to match the wide range of parameters that we have shown can now be measured, should take us from these first steps to the definitive answer as to how S0 galaxies form.

description: The ethanolic extract from leaves of Rauia resinosa, Rutaceae, provided a new flavone, 5-hydroxy-5’,6,7-trimethoxy-3’,4’-methylenedioxyflavone (1), in addition to four known compounds: 3’,4’,5,5’,7-pentamethoxyflavone (2), 5,7,8-trimethoxy-3’4’-methylenedioxyflavone (3), 3’,4’,5,7,8-pentamethoxyflavone (4) and β-sitosterol (5). The structures of all compounds were established on the basis of spectroscopic methods, mainly 1D and 2D NMR, UPLC-DAD-MS and UPLC-ESI-MS/MS, involving comparison with literature data. Cytotoxicity of leaves and stems extracts, their fractions and compounds (2), (3), (4) and (5) were evaluated against T24 (bladder carcinoma), TOV-21-G (ovarian adenocarcinoma) and HepG2 (liver carcinoma) cell lines.

description: Several species of the Inga genus are used by Amazonian indigenous communities to treat injuries, pain and inflammations, which is directly related to the presence of phenolic compounds in these species. Many studies have addressed the phytochemical relevance of this genus, but they are still few considering the large number of species. Therefore, this study aimed to investigate the chemical composition of Inga stipularis leaves in order to find compounds with potential pharmacological application and economic interest. The developed method allowed the isolation and identification of 8 compounds in the ethanol extract of I. stipularis: eucryphin, neoastilbin, astilbin, neoisoastilbin, isoastilbin, quercitrin, engeletin and isoengeletin. Astilbin stands out for having been isolated directly from the fractionation of the extract by SPE with high yield. This study was a pioneer for I. stipularis and revealed the potential of the species as an abundant source of compounds of pharmacological and economic interest.

description: Two new cycloartanes, combretic acid C (1) and combretanone I (3), were isolated from the leaves of Combretum quadrangulare Kurz, together with the previously-reported combretic acids A-B (2 and 5) and combretanone A (4). An extensive set of spectroscopic methods were used to elucidate the structures of these compounds. Cytotoxicity against the K562 cancer cell line was evaluated. Compound 1 showed strong activity, with an IC50 value of 9.7 µM. The other compounds showed moderate activity. Alpha-glucosidase inhibition was also evaluated. The isolated compounds showed moderate inhibition, with IC50 values in the range 102.2-194.7 µM.

description: Apicomplexan parasites use Ca2+-regulated exocytosis to secrete essential virulence factors from specialized organelles called micronemes. Ca2+-dependent protein kinases (CDPKs) are required for microneme exocytosis; however, the molecular events that regulate trafficking and fusion of micronemes with the plasma membrane remain unresolved. Here, we combine sub-minute resolution phosphoproteomics and bio-orthogonal labeling of kinase substrates in Toxoplasma gondii to identify 163 proteins phosphorylated in a CDPK1-dependent manner. In addition to known regulators of secretion, we identify uncharacterized targets with predicted functions across signaling, gene expression, trafficking, metabolism, and ion homeostasis. One of the CDPK1 targets is a putative HOOK activating adaptor. In other eukaryotes, HOOK homologs form the FHF complex with FTS and FHIP to activate dynein-mediated trafficking of endosomes along microtubules. We show the FHF complex is partially conserved in T. gondii, consisting of HOOK, an FTS homolog, and two parasite-specific proteins (TGGT1_306920 and TGGT1_316650). CDPK1 kinase activity and HOOK are required for the rapid apical trafficking of micronemes as parasites initiate motility. Moreover, parasites lacking HOOK or FTS display impaired microneme protein secretion, leading to a block in the invasion of host cells. Taken together, our work provides a comprehensive catalog of CDPK1 targets and reveals how vesicular trafficking has been tuned to support a parasitic lifestyle.

description: Virgin Olive Oil (VOO) shelf life is determined by the varietal-specific chemical composition and principally by the of phenolic composition. The aim of this study was to investigate the changes in fatty acid profile, phenolic composition, and quality parameters of nine Italian monovarietal VOOs obtained under the same pedoclimatic, agronomic and technological conditions and stored for 12 months at 15 °C in the dark. The varieties with medium-high concentrations of secoiridoids and balanced values between the individual molecules were those with the highest stability. Orthogonal Projections to Latent Structures (OPLS) regression revealed that oleuropein derivatives and phenolic alcohols had the highest antioxidant activity. OPLS discriminant analysis separated well fresh and stored oils. PV, K270, tyrosol, hydroxytyrosol, and oxidated oleacein were the most effective indicators of VOO ageing. Oleacein and oleocanthal decreased after storage, phenolic alcohols, oleacein and ligstroside aglycon increased.

description: Projects, in which software products, services, systems and solutions are developed, all rely on the right requirements to be established. Software requirements are the expression of user wants or needs that have to be addressed, business objectives that have to be met, as well as capabilities and functionality that has to be developed. Meanwhile, practice shows that very often incorrect, unclear or incomplete requirements are established, which causes major problems for such projects. It could lead to budget overruns, missed deadlines and overall failure in worst-case scenarios. The field of requirements engineering emerged as an answer to these shortcomings, aiming to systematize and streamline the process that establishes requirements. Requirements elicitation is a key component of this process, and one of its starting points. The current thesis attempts to outline best practices in requirements elicitation, as well as what issues, obstacles and challenges are currently faced, and then present this through the lens of national culture. In this way its effects on the practice, if any, could be highlighted and studied further. The way this was achieved was by interviewing practitioners from two nations, which are shown to be culturally different, and then comparing and contrasting the findings. Meanwhile, the validity of those findings was enhanced by comparisons with existing literature. Even though the findings were not compelling enough to form generalizations or concrete conclusions about the effects of national culture on requirements elicitation, these findings revealed patterns that could be worth exploring further. When it comes to requirements elicitation itself, it was observed to benefit from a structured and systematic approach, and be most effective with one-on-one, instead of group interactions. The main pain points of the process stem from the complexity of communication, but are not always obvious. Practitioners are also advised to carefully plan the gathering of requirements, as the source may not have them readily available, and could even be unclear about what exactly is needed. Overall, this thesis research could be considered successful in its goal to shed a modicum of light on the issue at hand from a different, underexplored angle. By following a systematic and methodical approach, this research has also been made easier to expand or replicate.

description: Die vorliegende Arbeit beschäftigt sich mit der Positionsbestimmung in Innenräumen mittels der Ultra Breitband Technologie, deren Genauigkeit sowie der Positionierung solcher Systeme in relevanten Beleuchtungsmodulen. Im ersten Teil der Arbeit wird die Ultrabreitband Technologie beschrieben, die sich für Ortbarkeit in Innenräumen durch die große Bandbreite, relativ gut eignet. Hierbei wird auf das UWB-Signal, die Regulierung bezüglich Frequenznutzung für Europa und USA sowie auf die UWB-Standards eingegangen. Im weiteren Verlauf der Arbeit werden die gegenwärtigen Positionsbestimmungs Verfahren beschrieben. Beispiele hierfür sind das Time of Flight (ToF), das Time of Arrival sowie nicht funkbasierte Methoden wie z. B. die Inertial Measurement Unit (IMU). Die Positionsbestimmung in der UWB-Technologie wird häufig mittels ToF und ToA bewerkstelligt. Im darauffolgenden Kapitel werden die gegenwärtigen Lokalisierungssysteme erklärt. Real Time Locating Systems (RTLS) kommen in vielen Lebensbereichen zum Einsatz, von Krankenhäusern bis zum Sport. Der zweite Teil der Arbeit besteht aus der Ausarbeitung von verschiedenen Konzepten zur Realisierung eines Demonstrators sowie der Ausarbeitung eines Simulationsmodells für die Positionsbestimmung, mit dem eine Ortungsgenauigkeit von 30 bis 50 cm erreicht werden kann.

description: Copaifera langsdorffii Desf. is recognised as one of most famous medicinal and economic species of Copaiba, occurring in several distinct biomes. An untargeted metabolomic approach was used to evaluate the chemical variability of C. langsdorffii from contrasting climates biomes (Atlantic Rainflorest and the semiarid Cerrado). Metabolomic analysis enabled the identification of 11 compounds, including glycosylated flavonoids and galloylquinic acid derivatives. Multivariate analysis highlighted that Cerrado population had a significantly higher concentrations of galloylquinic acid derivatives in comparison to the rainforest biome. Meanwhile, Atlantic Rainforest populations presented higher content of flavonols. Semiarid biome, reduced the concentration of flavonoids, mainly concerning quercetin and kaempferol derivatives, however, in this biome flavonoids were more diverse. Both chemical classes presented relevance to be used as geographical origin chemical markers by qualitative and quantitative features.

description: Several experiments (e.g., Milagro and IceCube) have reported the presence in the sky of regions with significant excess in the arrival direction distributions of Galactic cosmic rays in the TeV to PeV energy range. Here we study the possibility that these hotspots are a manifestation of the peculiar nature of these cosmic rays, and of the presence of molecular clouds near the sources. We propose that stable quark matter lumps or so-called "strangelets" can be emitted in the course of the transition of a neutron star to a more compact astrophysical object. A fraction of these massive particles would lose their charge by spallation or electron capture in molecular clouds located in the immediate neighborhood of their source, and propagate rectilinearly without decaying further, hence inducing anisotropies of the order of the cloud size. With reasonable astrophysical assumptions regarding the neutron star transition rate, strangelet injection and neutralization rates, we can reproduce successfully the observed hotspot characteristics and their distribution in the sky.

description: Meine Masterarbeit beschreibt im Grunde einen Diskussionsprozess eines Begriffs. Es geht um den Versuch einer Kategorisierung und Bestimmung der Illustrationen, also darum, inwiefern Illustrationen kategorisiert werden können und anhand von welchen Merkmalen bestimmt werden kann, ob es sich um eine Illustration handelt. Diese Untersuchung findet in der Designforschung nämlich nur marginal statt. Julius Wiedemann und der Illustrator Raban Ruddigkeit erklären in ihren Büchern zwar, was eine Illustration ausmacht, jedoch wird weder eine Taxonomie bzw. Definition explizit angeführt oder darauf verwiesen, es kann aus dem Text aber ein Verständnis und damit eine implizite Definition explizit gemacht werden. Laut Ruddigkeit sind Illustrationen mehr als bloß ein „Abbild der Wirklichkeit“ (Ruddigkeit 2021, Klappentext), denn eine Illustration „erhellt […] übertreibt […] mischt sich ein […] stößt […] Veränderung an […] interpretiert “ (Ruddigkeit 2021, Klappentext) Wiedemann verfolgt einen anderen Ansatz, denn laut ihm muss eine Illustration im Kontext funktionieren. (Vgl. Wiedemann 2007, 7f.) Die Masterarbeit verfolgt die Methode der relationalen Bestimmung nach Wiesing. (Vgl. Wiesing 2015, Einleitung) Es erfolgt zusätzliche eine Analyse von Literatur, insbesondere liegt der Fokus auf den Theorien unter anderem von Sybille Krämer, Steffen-Peter Ballstaedt, Nelson Goodman, Hartmut Stöckl, Vilem Flusser, Ludwig Wittgenstein und Roland Barthes. Verorten lässt sich die Arbeit in den Bereichen der Bildwissenschaften bzw. der Kategoriensysteme. Ein Begriff wird diskutiert, es wird kein Versuch angestrebt, eine endgültige Lösung zu finden. Die Diskussion wird in einem passenden und übersichtlichen Layout in der Arbeit präsentiert und theoretisch weiter ausgearbeitet, sowie durchdiskutiert. Im besten Fall ergeben sich Vorschläge für eine Definition, eine Möglichkeit zur Kategorisierung bzw. Erhellungen zur Illustration, ohne sie endgültig definieren zu müssen. Wir können von einem Theater der Begriffsbestimmung sprechen, welches am Fallbeispiel der Illustration inszeniert wird. Die Absicht der Masterarbeit ist somit nicht, eine endgültige Taxonomie aufzustellen, sondern die Diskussion zu eröffnen und Einsichten zu liefern. Mittels Überlegungen, Erkenntnissen aus Experimenten bzw. Analysen, Recherche und Forschung durch Design möchte ich versuchen, diesem komplexen Feld näher zu kommen. Diese Erkenntnisse sollen als Basis für weiterführende Forschung betrachtet werden. Fragen werden gestellt, diese müssen jedoch nicht im Zuge dieser Arbeit beantwortet werden. Meine Forschungsfrage lautet somit folgendermaßen: Wie kann der Bestimmungsprozess zu einem Begriff offengelegt werden und zu einem fruchtbaren Ergebnis bzw. einer Einsicht führen, am Beispiel des Begriffs Illustration, ohne eine endgültige Lösung anzupeilen?

description: Power cables play an important role in power grids. Insulation faults in cables can have adverse effects on the operating behaviour. These effects can be assessed through an AC withstand test by using a very-low frequency high voltage generator. This generator produces a sinusoidal voltage waveform at 0.1Hz with high voltage levels up to 65kV peak. During the quality assessment, the power cable is repeatedly charged and discharged. The discharging process is done by a discharging circuit where the energy is dissipated thermally. But to reuse the dissipated energy a novel extension in form of an energy storage system is presented. This thesis, therefore, describes the design process of an energy storage system that allows the temporary storage of the discharge energy. The developed system is composed of a bidirectional DC/DC converter and an aluminium electrolytic capacitor as storage type. Based on the maximum VLF system ratings the energy storage unit is dimensioned and sized. The effective power flow control between the storage system and the available discharge energy is done by a synchronous buck-boost converter. This bidirectional converter works in continuous conduction mode over the complete charging phase. Together with a theoretical analysis of the underlying problem and the use of converter analysis methods the selected synchronous buck-boost converter is dimensioned and sized. In addition, a state space AC modeling of the converter with its electrical uncertainties is conducted. With the converters AC model, the controller is designed. A closed-loop input converter current control scheme based on a proportional-integral controller is implemented. The system assessment is done by a model-based hardware implementation in Matlab Simulink and Plecs Blockset. The system is rated to store discharge energies up to 4.3kJ in a short charging period of 2.5s. The maximum peak power during the charging phase is 2.7kW. The digital proportional-integral controller is implemented through an emulation process of the designed analog controller. Based on a C-code implementation of the digital controller the gap between the real hardware is reduced. During the design process theoretical calculations are made and reveal that designing a capacitor storage unit has a direct impact on the peak system currents and also impose also limitations on permissible DC voltage ranges on electrical components. The developed energy storage system and its power flow control strategy were investigated through simulation studies. The results show proper charging of the energy storage medium. In addition, also a statement of the final technical feasibility is made. In total, this work summarizes a detailed design process of the energy storage system. This proof of concept is intended to further advance the system integration.

description: We present a study of the structural and electronic properties of highly doped topological insulator Bi2Se3 single crystals synthesized by the Bridgman method. Lattice structural characterizations by X-ray diffraction, scanning tunneling microscopy, and Raman spectroscopy confirmed the high quality of the as-grown single crystals. The topological surface states in the electronic band structure were directly re- vealed by angle-resolved photoemission spectroscopy. Transport measurements showed that the conduction was dominated by the bulk carriers and confirmed a previously observed bulk quantum Hall effect in such highly doped Bi2Se3 samples. We briefly discuss several possible strategies of reducing bulk conductance.

description: In today’s world, fiber optic networks for data transmission are an essential technology. This technology provides multiple advantages compared to conventional electrical data transmission. The simultaneous transmission of multiple optical signals in a single fiber is one of the main benefits of fiber optic cable. This is accomplished by directing the different optical signals into a single fibre and splitting them up after the transmission in order to obtain the individual signals. Arrayed Waveguide Gratings (AWGs) are used for this purpose in modern optical networks. Design and evaluation process are two components of AWG development. During the evaluation of several simulated and already manufactured AWGs for telecommunication applications, it was discovered that the channel spacing parameter does not conform telecommunication standards. The correct shift of the geometric parameter ”separation of the output waveguides” leads to the standard-conform channel spacing. According to the current state of the art, no commercial tool is available which calculates the shift of this parameter correctly. The aim of this thesis is the development of a software tool to calculate the accurate shifting of the geometric parameter ”separation of the output waveguides” of an AWG. This tool operates as an interface between the design and evaluation processes and must be able to import the data format of the evaluation process and returns the data in a suitable data format for the design process. The Vorarlberg University of Applied Sciences uses three different methods for the shifting of the geometric parameter ”separation of the output waveguides”. These methods are evaluated and optimised as part of this thesis. Additionally, it has been determined that the shift of the geometric parameter ”separation of the output waveguides” has no significant impact on the performance of the AWG.

description: Three new α-glucosidase inhibitory benzo-isochromenes were isolated from the chloroform fraction of Datura stramonium. Their structures were established with the help of modern spectroscopic techniques and were assigned the names as 1,6,8-triimethoxy-2-methyl-3,4-dihydrobenzoisochromene-5,10-diol, 3,6-dimethoxy-5-hydroxy-4-methylbenzoisochromene-9,11-dione and demethylflavasperon for compounds 1-3 respectively. The α-glucosidase inhibiting activity of compound 2 showed strong inhibition with an IC50 value of 27.5 µM, while compound 1 exhibited moderate activity with IC50 value of 60.2 µM compared to positive control (acarbose).

description: The influence of a magnetic field on the broadening of spectral lines and transition arrays in complex spectra is investigated. The anomalous absorption or emission Zeeman pattern is a superposition of many profiles with different relative strengths, shifts, widths, asymmetries and sharpnesses. The "sigma" and "pi" profiles can be described statistically, using the moments of the Zeeman components. We present two statistical modellings: the first one provides a diagnostic of the magnetic field and the second one can be used to include the effect of a magnetic field on simulated atomic spectra in an approximate way.

description: The following thesis covers the miniaturization and characterization of a pneumatic syringe pump, which is used for applications in low-pressure liquid chromatography. For this purpose, the components of the prototype are dealt with in the first section. These include the membrane pump and the cylinder for pressure and force generation, the syringe used for sample preparation and the construction of the test column. Furthermore, the pressure preparation on the cylinder, the friction losses of the syringe and then the behavior of the syringe in various application scenarios are considered. In the second section, the focus is on the different behaviors when using water and ethanol as a solvent. Tests in normal applications, as well as with air pockets or leaking seals, show the different behavior and the resulting deviations in the test pressure of the column. In addition, the maximum forces that can be applied to the syringe are worked out in several tests and the different maximum pressures, which depend on the solvent contained, are evaluated. These different maximum pressures, which are due to the different sealing behavior in connection with the surface tension of the liquid, will be discussed in conclusion. An outlook follows, up to which test pressures the system can be used and how these can be achieved.

description: A detailed close phytochemical investigation of the fruits of Ternstroemia cherryi led to the isolation and identification of the minor metabolite, ternstroenol F, which possessed the usual barrigenol-like terpenoid backbone. The notable difference was that this minor metabolite had the 2(E)-4(Z)-6(E)-decatrienoic acid forming an ester bond at C-22 of the oleanane backbone. Ternstroenol F was evaluated for its inhibitory effects on NO inhibition, cell viability and TNF- α release in RAW 264.7 macrophages, displaying an IC50 values of 0.23, 0.81 and 1.84 µM respectively.

description: Stachys is a large genus of economically important plants belonging to Lamiaceae family that includes about 300 species as annual or perennial herbs. Several species of this genus are extensively used in various traditional medicines. In the present study the chemical composition of the essential oil from aerial parts of Stachys spreitzenhoferi Heldr., a very rare plant, belonging to Section Candidae, endemic of South Greece and collected in the island of Kythira, was analysed by GC-MS. No one reports have been previously published on this species. The result showed the presence of large quantity of diterpenoids with manoyl oxide (22.1%), as the most abundant component. Other metabolites present in high quantity were trans-nerolidol (18.5%), β-caryophyllene (11.0%) and germacrene D (8.1%). Chemotaxonomic considerations with respect all the other oils of Stachys taxa, belonging to the same section studied so far, were carried out.

description: A new glycoside, recurvataside (1) and six known compounds, quinovic acid (2), quinovic acid 28-O-β-D-glucopyranosyl ester (3), 3-O-β-D-glucopyranosylquinovic acid (4), 3-O-β-D-glucopyranosylquinovic acid 28-O-β-D-glucopyranosyl ester (5), pomolic acid (6), and ursolic acid (7) were isolated from aerial parts of Mussaenda recurvata. The structure of compound 1 was identified from its spectroscopic data and by comparison with the literature. Recurvataside represents the first occurrence of δ-oleanolic acid saponin bearing two D-glucose units at C-3 and C-28 in nature. This is the first time δ-oleanane-type saponin reported in the genus Mussaenda. Compounds 1-7 were evaluated the cytotoxicity against two cancer cell lines MCF-7 and HepG2. Among them, only compound 7 exhibited moderate activity against MCF-7 and HepG2 cell lines with IC50 value of 16.97 ± 1.55 and 20.28 ± 1.00 μM, respectively. Compounds 1–7 were also tested for their inhibitory NO production in LPS-stimulated RAW264.7 cells. Compounds 3, 5, and 7 showed significant reduction of nitrite accumulation in LPS-stimulated RAW 264.7 cells with the IC50 values of 8.81 ± 0.48, 13.42 ± 0.84, and 18.37 ± 0.67 μM, respectively.
