description: The article explores the concept of «retail». Peculiarities of retail development in the banking sector of Ukraine are analyzed. It is established that banking technologies are another of the most important factors of successful development in modern conditions of banking retail. Banks create a customer-oriented model of doing business, offering specific types of services to specific groups of customers, trying to implement the prin-ciple of individual customer service. An urgent issue today is to determine the main trends in the development of retail banking. Research on the nature of retail in the banking sector and identified its role in expanding the service sector by introducing the latest innovative services in commercial banks to maximize income and main-tain their liquidity. The development of above-indicated promising areas will allow banking institutions to continue to cover almost all areas of the financial services market.

description: We have investigated the lattice thermal transport across the asymmetric tilt grain boundary between armchair and zigzag graphene by nonequilibrium molecular dynamics (NEMD). We have observed significant temperature drop and ultra-low temperature-dependent thermal boundary resistance. More importantly, we find an unexpected thermal rectification phenomenon. The thermal conductivity and Kapitza conductance is direction-dependent. The effect of thermal rectification could be amplified by increasing the difference of temperature imposed on two sides. Our results propose a promising kind of thermal rectifier and phonon diodes based on polycrystalline graphene without delicate manipulation of the atomic structure.

modern Ukrainian newspaper text.

description: The article analyzes the approaches to distinguishing the categories of newspaper texts, reveals the con-cept of "media linguistics", "media text" taking into account the genre and style features. Particular attention is paid to the journalistic style, which is characterized by high subjectivity and close personal connection be-tween the author of the text, the text itself and the recipient. It is established that information and text are usu-ally not identified, because everyone perceives the information covered in the same text differently. It has been observed that modern mass media are more and more clearly influencing the consciousness of the modern re-cipient. The genre originality of newspaper texts is structured and analyzed by groups: analytical, informa-tional and artistic-journalistic. Pragmalinguistic functions of lexical-syntactic repetition in genre varieties of modern Ukrainian newspapers are determined.

description: A technology-independent, mathematical approach is proposed for the look-up-table based nonlinear modeling of electron devices. The model allows for accurate large-signal performance prediction at high operating frequencies, even in the presence of important parasitic and low-frequency dispersive effects. All the notitinear functions which characterise this black-box model are directly related to conventional measurements which can be carried out with automatic instrumentation. Preliminary experimental results are presented which confirm the validity of the approach.

description: Zielsetzung: In der vorliegenden Arbeit wurden alle 72 Lebendnierenspender die zwischen 1995 und 2007 eine Niere gespendet haben retrospektiv untersucht und ihr Befinden nach der Spende analysiert. Methode: Es erfolgte die Datenerfassung mittels eines Fragebogens sowie Patientenakten. Subjektives Befinden, Narbenschmerz und Arbeitsfähigkeit nach der Spende wurden mit den Variablen Explantationsseite der Niere und der Operationsmethode (offen oder laparoskopisch handassistiert) in Beziehung gesetzt. Ergebnisse: Über 90% der Spender gaben einen guten Gesundheitszustand mit wenig Narbenschmerzen an. Rückblickend würden sich 94% der Spender erneut für eine Spende entscheiden. Der postoperative stationäre Aufenthalt war nach laparoskopischer Operationsmethode signifikant kürzer. Zwischen den OP-Methoden gab es sonst keine signifikanten Unterschiede. Die Rücklaufquote der Fragebögen betrug 78,8%. Schlussfolgerung: Die laparoskopische OP-Methode ist eine sichere Methode mit einem guten Befinden der Lebendnierenspender nach der Spende. Sie wird aufgrund des bestehenden Organmangels weiter an Bedeutung gewinnen.
description: Objective/target: The aim was to analyze the state of health in 72 living kidney donors who donated a kidney between 1995 and 2007. Method: The data was collected with a questionnaire in conjunction with the patient’s hospital records. Subjective condition, scar pain and ability to work after the donation were taken into consideration with relation to the variable site of explantation and the method of operation (open or laparoscopically hand-assisted). Results: Over 90% of the donors stated a good condition of health and little scare pain. Retrospectively, 94% of the donors were satisfied with their decision to donate a kidney and would make the same decision again if asked. The post operational length of hospitalization was significantly shorter after the laparoscopical method of operation. Apart from reduced recovery time, there were no significant differences between the operational methods. The return rate of the questionnaires was 78%. Conclusion: The laparoscopical method of operation is a safe method with a good outcome of health condition after the donation. Due of the general shortage of donor organs, this method will be the main focus of interest in the future.

description: Based on 2D hydrodynanuc energy model which features transient simulation of degenerate hot elec­tron transport in submicron MODFETs, we present a detailed analysis of single quantum well (SQW) AlGaAs/GaAs/AlGaAs MODFETs which are proposed to enhance and optimize the device millimetric performance. The structure have been studied for different QW widths as well as different buffer AlGaAs transport parameters. It is demonstrated that hot electron effects set an upper limit on the maximum available gain and maximum oscillation frequency of the structure.

description: In den zwei dieser Arbeit zu Grunde liegenden psychoakustischen Versuchen werden Aspekte der binauralen Verarbeitung durch das menschliche Gehör bei schmalbandigem Rauschverdecker und zu detektierenden Signalen außerhalb des Frequenzbereichs des Rauschverdeckers untersucht. Im ersten Versuch werden Detektionsschwellen für diotische und dichotische Tonsignale für Signaldauern von 12 und 600 ms in einem Verdeckungsmuster-Versuch ermittelt und mit Simulationsergebnissen desselben Versuchs verglichen. Die Simulationen zeigen, dass der Effekt der Signaldauer auf den binauralen Gewinn im Falle eines spektral nicht im Verdecker liegenden Signals im wesentlichen auf Schwebungen beruht, die nur in der monauralen Detektion bei langen Signaldauern genutzt werden können. Im zweiten Versuch wird die Kombination von binauralen Merkmalen und Modulationsmerkmalen untersucht. Dazu werden Detektionsschwellen für ein durch ein diotisches Schmalbandrauschen verdecktes Schmalbandrauschen gemessen und dabei die Korrelation der Einhüllenden der Rauschen, die interaurale Phasendifferenz des Zielrauschens sowie der Abstand der Mittenfrequenzen der Rauschbänder variiert. Die Differenz der Schwellen zwischen Bedingungen mit komodulierten und unkorrelierte Einhüllenden von Zielrauschen und Verdecker hing weder von der Mittenfrequenz des Zielrauschens noch von der interauralen Korrelation ab. Dies deutet darauf hin, dass binaurale Merkmale und Modulationsmerkmale unabhängig voneinander verarbeitet werden.

Es wurden 6 Selbstbeurteilungsbögen (B-L, SCL-90-R, F-SOZU, Beziehungsfragebogen, SF-36, Fragebogen zur Lebenszufriedenheit) und ein 30-60 minütiges halbstrukturiertes Interview verwendet. Postoperativ kam es zur leichten Zunahme der psychischen und physischen Beschwerden, zur Verschlechterung der Beziehungsqualität und zur Abnahme der sozialen Unterstützung. Die psychosoziale Belastung dagegen nahm postoperativ ab. Die postoperativen Werte waren vergleichbar mit denen der deutschen Normstichprobe.
description: By questioning 23 donor-recipient-pairs before and after a kidney donation, this study examines the effects a living kidney donation has for donors as well as recipients in regard to the physical and psychosocial life, the quality of relationships, self-contentment and quality of life. 6 selfassessment-questionnaires (B-L, SCL-90-R, F-SOZU, questionnaire concerning relationships, SF-36, questionnaire concerning self-contentment) were used and semi-structured-interviews of 30-60 minutes were conducted. Postoperative there was a moderate increase of mental and physical stress, weakening of relationships and decline of social support. In contrast the psychosocial strain decreased. The postoperative data are comparable to the German reference group.

description: Traditional tools fail to capture the value of new ventures, such as R&D
projects and start-up companies, because of their dependence on future
events that are uncertain at the time of the initial decision. In the real
options setting the value of these investments is the value of the follow-on
opportunities they may create. Our aim is to study the multicompound
option approach to value sequential investment opportunities taking into

It is revealed that a positive effect in the form of an increase in productivity and reduction of expenses as a result of application of modern sowing complexes of precision sowing of corn is possible when bringing all components of the sowing technology to perfection. Factors of soil preparation for sowing in order to preserve spring moisture in the soil, ensure soil leveling and prepare high-quality seedbed are analyzed. The im-portance of choosing sowing dates in order to obtain simultaneous germination of corn is emphasized. Possi-bilities of modern computerized sowing complexes as an element of precision sowing are clarifired.
Lateral behaviour and direct displacement based design of a novel hybrid structure : cross laminated timber infilled steel moment resisting frames
Creators: name: Bezabeh, Matiyas
Publisher: name: University of British Columbia
Year: 2014

description: Recently, an innovative hybrid structure has been developed as an alternative lateral-load resisting system at The University of British Columbia. The hybrid structure incorporates Cross Laminated Timber (CLT) shear panels as an infill in steel moment resisting frames (SMRFs). In order to increase the applicability of the proposed system, in this thesis, a direct displacement based design methodology has been developed and analytically validated. Initially, a nonlinear time history analysis (NLTHA) was carried out to study the lateral behaviour of the proposed hybrid structure. For this purpose, a total of 162 different hybrid buildings were modeled and analyzed in OpenSees by using twenty earthquake ground motions (2% probability exceedance in 50 years). Post-earthquake performance indicators (Maximum Interstory Drift (MISD) and Residual Interstory Drift (RISD)) were obtained from the analyses. To assist the post-seismic safety assessment of the hybrid buildings, surrogate models for MISD and RISD were developed using Response Surface Methodology and Artificial Neural Network (ANN). By using the ANN surrogate models as fitness functions for the Genetic Algorithm, optimal modeling parameters of the hybrid system were obtained. Secondly, to represent the energy dissipative capacity of the hybrid system, an equivalent viscous damping (EVD) equation was developed. To formulate the EVD equation, 243 single-storey single-bay CLT infilled SMRF models were developed and subjected to monotonic static and semi-static cyclic analysis. The EVD of each model was calculated from the hysteretic responses based on Jacobsen's area based approach and later calibrated using NLTHA. Finally, an iterative direct displacement based design method was developed for the proposed hybrid structure. A detailed description of the proposed methodology is presented with a numerical example. In order to verify the proposed method, hybrid buildings with 3-, 6-, and 9- storey heights were designed. A calibrated EVD-ductility relationship was used to obtain the energy dissipation of the equivalent SDOF system for all case study buildings. Nonlinear time history analysis using twenty ground motion records was used to validate the performance of the proposed design methodology. The results indicate that the proposed design method effectively controls the displacements resulting from the seismic excitation of the hybrid structure.

description: We consider scalar quantum electrodynamics in the Higgs phase and in the presence of Lorentz violation. Spontaneous breaking of the gauge symmetry gives rise to Lorentz-violating gauge field mass terms. These may cause the longitudinal mode of the gauge field to propagate superluminally. The theory may be quantized by the Faddeev-Popov procedure, although the Lagrangian for the ghost fields also needs to be Lorentz violating.

description: Peptide und Proteine stehen zunehmend für verschiedene Therapien zur Verfügung. Es müssen jedoch angemessene Arzneimittelverabreichungssysteme entwickelt werden, um eine optimale klinische Anwendung zu ermöglichen. In dieser Arbeit wurde ein in situ bildende Implantat entwickelt, das poly (glycerinadipat)-g-oleat (PGA-g-Ox) verwendet. Nach der Synthese und Charakterisierung wurde ein direkt injizierbares, lösungsmittelfreies System erhalten. Es bildet unmittelbar nach subkutaner Injektion mit einer kurzen, schmalen Kanüle ein Depot, ohne dass eine Gelierzeit benötigt wird. Danach zeigte das mit Leuprolidacetat formulierte viskose Polymer über vier Wochen ein kontrolliertes Wirkstofffreisetzungsprofil. Der In-vitro-Zytotoxizitätstest, der an 3T3-Mausfibroblastenzellen durchgeführt wurde, hat eine gute Biokompatibilität gezeigt. Eine präklinische Studie, die an SKH1-Nacktmäusen durchgeführt wurde und durch nicht-invasive Fluoreszenzbildgebung beobachtet wurde, hat den Einfluss der Viskosität und Form des Implantats auf die Diffusion des Modellsarzneimittels nachgewiesen.
description: Peptides and proteins are increasingly available for different therapies. However, adequate drug delivery systems need to be developed to enable the optimal clinical application. In this study, an in situ forming implant has been developed using poly(glycerol adipate)-g-oleate (PGA-g-Ox). After the synthesis and characterization, a directly injectable, solvent-free system has been obtained. It forms a depot immediately upon subcutaneous injection using a short, narrow cannula, with no need for a gelation time. Following that, the viscous polymer formulated with leuprolide acetate has shown a controlled drug release profile over four weeks. In vitro cytotoxicity assay carried out on 3T3 mouse fibroblast cells have presented good biocompatibility. Finally, a preclinical study, conducted on SKH1 nude mice and observed by non-invasive fluorescence imaging, has evidenced the influence of the viscosity and shape of the implant on the model drug diffusion.

description: We prove explicit, i.e. non-asymptotic, error bounds for Markov chain Monte Carlo methods. The problem is to compute the expectation of a function f with respect to a measure π. Different convergence properties of Markov chains imply different error bounds. For uniformly ergodic and reversible Markov chains we prove a lower and an upper error bound with respect to the L2 -norm of f . If there exists an L2 -spectral gap, which is a weaker convergence property than uniform ergodicity, then we show an upper error bound with respect to the Lp -norm of f for p > 2. Usually a burn-in period is an efficient way to tune the algorithm. We provide and justify a recipe how to choose the burn-in period. The error bounds are applied to the problem of the integration with respect to a possibly unnormalized density. More precise, we consider the integration with respect to log-concave densities and the integration over convex bodies. By the use of the Metropolis algorithm based on a ball walk and the hit-and-run algorithm it is shown that both problems are polynomial tractable.

description: Monolithic integrated circuit switches can be fabricated using either GaAs FETs or with PIN diodes as the active elements. Each offers advantages and disadvantages to the circuit design. It has been shown that because of their higher switching Q1,4 that PIN diodes should exhibit lower loss and higher isolation in the same circuit than a switch made with a FET as the switching element. Conversely, FET based switches offer an advantage of less control power and better DC to RF isolation of the control currents. This paper will discuss a family of MMIC PIN diode based SPDT switches which are designed to give the lowest loss and best isolation from 2-18 GHz. In order to minimize losses from the passive elements such as inductors, capacitors and RF lines, these are built in a GMIC3 circuit (glass microwave circuit). The active elements (PIN diodes) are built on a HETEROLITHIC circuit. In a HETEROLITHIC circuit the PIN switching elements are suspended in a low loss tangent, low dielectric borosilicate glass. This glass reduces the normal loss seen in RF lines on silicon or gallium arsenide. It's smaller dielectric also allows larger conductor lines, without excess capacitance to ground. The GMIC circuit is designed to allow either a silicon PIN or GaAs PIN switch interchangeable as the active element. Several broadband circuits were built with the designed frequency being 2-18 GHz. Electrical results are excellent, with loss (including all circuit elements) being -0.8 dB at 18 GHz and isolation being >35 dB.

description: Proteinkinaseinhibitoren spielen eine wichtige Rolle in der modernen Krebstherapie. Ein großes Problem bei der Therapie mit diesen selektiv wirksamen Substanzen stellt die rasche Entwicklung von Resistenzen dar. Eine Möglichkeit der Resistenzentstehung ist die Heterodimerisierung der Proteinkinasen EGFR und IGF-1R. Im Rahmen der vorliegenden Arbeit wurde die Resistenzüberwindung durch duale Inhibition dieser beiden krebsrelevanten Kinasen untersucht. Es wurden mehrere potenziell wirksame Substanzen synthetisiert. Der gemeinsame Grundkörper dieser Verbindungen ist ein 1-Aza-9-oxafluoren bzw. a-Carbolin. Synthesewege und Reaktionsmechanismen werden ausführlich diskutiert. Es wurden 41 Verbindungen in vitro an den beiden Targetproteinen getestet. Struktur-Wirkungs-Beziehungen wurden mithilfe des molekularen Dockings untersucht. Die wirksamsten Substanzen wurden in vitro an mehreren Krebszelllinien getestet. Erste Ergebnisse zeigten den Rückgang des Wachstums einiger dieser Zellen.
description: Protein kinase inhibitors play an important role in modern cancer therapy. One of the main problems in clinical use of these selective compounds is the fast development of resistances. Heterodimerisation between the protein kinases EGFR and IGF-1R is a possible reason for the emergence of resistances. In this work the overcoming of resistance by dual inhibition of these two kinases is investigated. A pool of prospective active substances was synthesised. The common molecular structure of these compounds is a 1-aza-9-oxafluorene or a a-carboline respectively. Synthetic pathways and reaction mechanisms are discussed in detail. In vitro testing at the targeted proteins was performed with 41 compounds. Structure-activity relationships were investigated with the help of molecular modelling. The most active substances were tested in vitro on several cancer cell lines. First results showed a recession of growth in some of these cells.

description: We reexamine the right-handed current effects in $b \to s$ transitions in nonmanifest left-right models. Using the effective Hamiltonian approach including all possible low-energy operators, we obtain especially the B \to K πdecay amplitudes including annihilation contributions, and investigate the right-handed current contributions to CP asymmetries in $B \to K π$ decays. Taking into account the constraints from global analysis of muon decay measurements, |V_{ub}| measurements in inclusive and exclusive B decays, and $B_s^0-\bar{B_s^0}$ mixing measurements, we find the allowed regions of new physics parameters satisfying the current experimental data.

description: Nearly half of the world’s turtle species are endangered or threatened with extinction. Conservation efforts need effective sampling programs that provide high quality life history and population parameters on which to base management decisions. These parameters vary from one population to the next, as well as across a species’ geographic range, and local variation can be high. In this thesis, I investigate conventional trapping methodologies and examine potential biogeographical trends in body size and degree of sexual dimorphism in the painted turtle, Chrysemys picta. Painted turtles in the Okanagan valley of British Columbia, Canada, are nationally listed as Special Concern. Using hoop nets, basking traps, and dip nets, I sampled 13 ponds representing the range of occupied habitats in the valley. My results demonstrate that combining all three trap methods resulted in the highest recapture rates and more precise population estimates than single trap methods alone. Overall, hatchlings and juveniles were best caught by dip netting, and hoop traps performed the worst for adults of both sexes. Capture success of each trap method was not consistent across ponds, and each trap method performed poorly in at least one pond, pointing to the need to combine trap methods to get the most representative sample possible. My thesis research strongly suggests that combining conventional turtle trapping methods in a sampling program can provide stronger inference than a single method alone. I assessed the average body size and the degree of sexual size dimorphism for the turtles at each pond. Painted turtles in the Okanagan are bigger than their southern conspecifics, supporting Bergmann’s rule which asserts an inverse relationship between temperature and body size. There was no trend between latitude and degree of dimorphism. My work shows that local variation in biogeographic analyses suggests previously published biogeographic trends for C. picta may not be accurate. More research on the causes of local variation in size and growth rate will be valuable in the efforts to protect this and other turtle species in British Columbia.

description: Multidrug Resistance-Associated Proteins (MRP) transportieren ein breites Spektrum unterschiedlicher Substrate, daher wurde eine Beteiligung dieser Proteine an der Elimination von Arsenit, Cu(II) und Hg(II) in humanen Lungenzellkulturen untersucht. Zunächst wurde die Eignung von Primärkulturen normaler humaner Bronchialepithelzellen (NHBE-Zellen) als Modellsystem zur Erforschung einer Modulation der Expression von MRP1 - 5 und des Ubiquitously Expressed Mammalian ABC Half-Transporter (UMAT) in Langzeitkulturen geprüft. Sowohl die Ergebnisse von Zytotoxizitätstests (MTT-Assay), als auch von Genotoxizitätstests (Comet-Assay) sprechen für einen Beitrag von MRP-Transportern zum Schutz von H322 Zellen vor Arsenit. In NHBE-Zellen gibt es nach Untersuchung der Expression in Langzeitexperimenten mittels Real-time RT-PCR Hinweise auf eine Modulation besonders von MRP3 durch Arsenit und Hg(II). Die Effekte sind jedoch von Donor und Inkubationszeit abhängig. Im Gegensatz dazu deuten die Ergebnisse nicht auf einen Beitrag der untersuchten MRP-Transporter zur Homöostase von Cu(II) in den untersuchten Lungenzellkulturen hin. Inkubation von NHBE-Zellen für 72 h mit Cd(II), Co(II) und Pb(II) in Konzentrationen in Höhe der im Jahre 2003 für das Biomonitoring exponierter Arbeiter gültigen Grenzwerte, hat signifikante Effekte auf die RNA-Expressionsmuster der Zellen, was mittels Microarray-Analyse gezeigt werden konnte.

description: Die Tuberkulose ist ein weltweites und aktuelles Problem, deren Resistenzsituation sich wegen langen Therapiezeiten und inadäquat geführten Behandlungen weiter zuspitzt. In vorliegender Arbeit wurden bekannte Resistenzmechanismen diskutiert und versucht, durch die Synthese von 48 neuartigen 1,4-Dihydropyridinen (DHP) ein Wiederansprechen von gängigen Wirkstoffen zu ermöglichen. Dabei wurden Transporter-hemmende Eigenschaften an P-GP abgeschätzt und anschließend die antimykobakterielle Aktivität alleine und in Kombination mit Isoniazid, Ethambutol, Rifampicin, Clofazimin und Ciprofloxacin untersucht. Neben eigenen Wachstumshemmungen der DHP am Laborkeim GFP-H37Rv, wurden ebenso Steigerungen der Effektivität von Isoniazid, Clofazimin und Ciprofloxacin durch die DHP festgestellt. Für die Wirkungssteigerung kommen aufgrund der Ergebnisse des P-GP-Essays Effluxpumpen in Frage, wobei konkrete Targetproteine anhand von Vergleich mit Literatur und Proteindatenbanken postuliert werden konnten.
description: Tuberculosis is an worldwide problem whose resistance situation is worsening due to long and inadequately administered treatments. In the present work, known mechanisms of resistance were discussed and attempts were carried out to enable the re-use of established drugs by the synthesis of 48 novel 1,4-dihydropyridines (DHP). First, transporter-inhibiting properties on P-GP were examined, then the antimycobacterial activity was investigated alone and in combination with isoniazid, ethambutol, rifampicin, clofazimine and ciprofloxacin. In addition to growth inhibition in the laboratory germ GFP-H37Rv, which emanated from the DHP alone, also increases in the effectiveness of isoniazid, clofazimine and ciprofloxacin were detected. Due to the results of the P-GP essay, the inhibition of efflux pumps is considered to increase the effect, whereas specific target proteins could be postulated by comparsion with literature and protein databases.

description: Since the beginning of the third millennium, there were two world crises in financial markets: it now appears that a third one is beginning. Underlying the phenomenon are the behaviours of key stakeholder investors, who assumed the role of short- and very short-term "speculators". However, the work of ratings agencies, which sometimes have issued assessments which proved to be totally unreliable, has also to be acknowledged, among the causes of the crisis. This paper will also examine the possible effects of crisis on the economic and financial balance and, consequently, on the financial statement of companies, particularly referred to the Italian one.

description: Perorale Nanopartikel gelangten in den letzten Jahren vermehrt in den Fokus der Wissenschaft. Die Untersuchung des gastrointestinalen Verhaltens und der Einfluss intestinaler Verdausäfte auf diese Partikel sind daher essentiell. In dieser Dissertation wurden Lipidnanopartikel aus Cetylpalmitat und Polymernanopartikel aus PLGA mit der pH-stat Methode sowie Referenzmethoden, wie HPTLC, untersucht und das Ausmaß des enzymatischen Abbaus durch die pankreatische Lipase bestimmt. Im Weiteren wurde der Einfluss von diversen Stabilisatoren auf den Verdau sowie der Verdau der Stabilisatoren selbst untersucht. Zur Beobachtung des in vivo Verhaltens der peroral applizierten Partikel wurde die nicht invasive Fluoreszenzbildgebung im Mausmodell angewendet. Hierbei konnten für die fluoreszenzmarkierten Partikelformulierungen Transit-Zeit-Profile erstellt sowie Aussagen zum Verdau, zur Aufnahme und den Interaktionen mit der Schleimhaut im Gastrointestinaltrakt getroffen werden.
description: In the last decade peroral nanoparticles get more in the focus of research. The knowledge about behavior and fate of nanoparticle formulations in the gastro intestinal tract is of central concern for the rational design of peroral drug delivery systems. In this thesis lipid nanoparticles of cetyl palmitate and polymer nanoparticles of PLGA were investigated in vitro by the pH-stat method and different reference methods like HPTLC. The impact of pancreatic lipase on the particle digestion was determined as well as the influence of various stabilizers. A mouse model for the in vivo monitoring of fluorescence-marked particles was developed by using non-invasive multispectral fluorescence imaging. Thereby transit-time-profiles were recorded and the digestion, the uptake and interaction with mucus of these particles were analyzed in more detail.

description: Let $K$ be an algebraic function field of one variable with constant field $k$ and let $C$ be the Dedekind domain consisting of all those elements of $K$ which are integral outside a fixed place $\infty$ of $K$. When $k$ is finite the group $GL_2(C)$ plays a central role in the theory of Drinfeld modular curves analagous to that played by $SL_2(Z)$ in the classical theory of modular forms. When $k$ is finite (resp. infinite) we refer to a group $GL_2(C)$ as an arithmetic (resp. non-arithmetic) Drinfeld modular group. Associated with $GL_2(C)$ is its Bruhat-Tits tree, $T$. The structure of the group is derived from that of the quotient graph $GL_2(C)\backslash T$. Using an elementary approach which refers explicitly to matrices we determine the structure of all the vertex stabilizers of $T$. This extends results of Serre, Takahashi and the authors. We also determine all possible valencies of the vertices of $GL_2(C)\backslash T$ for the important special case where $\infty$ has degree 1.

description: Zur Untersuchung der Stereochemie von Matairesinol in der Asteraceenspezies Carthamus tinctorius wurde eine CE-Methode zur Enantiomerentrennung entwickelt. Mithilfe dieser Methode konnte sowohl in den Früchten als auch in den Stängeln der Spezies ausschließlich das (-)-Enantiomer nachgewiesen werden. Die Untersuchungen zu den estrogenen, antiestrogenen und antioxidativen Aktivitäten von Lignanen wurden sowohl an den Standards als auch an lignanhaltigen Asteraceenextrakten durchgeführt. Die untersuchten Lignane zeigten im DPPH- und FRAP-Test ein antioxidatives Potential, welches vergleichbar war mit demjenigen von Ascorbinsäure, teilweise sogar höher. Von den untersuchten Extrakten erwiesen sich die aus drei Arctium-Arten als besonders stark antioxidativ. Die wirkbestimmende Komponente waren hier jedoch offensichtlich nicht die Lignane. Mit dem YES-Assay ließ sich für verschiedene pflanzliche und semisynthetische Lignane sowie für die Enterolignane eine agonistische oder antagonistische Aktivität am Estrogenrezeptor α nachweisen. Eine starke estrogene Wirkung zeigte das pflanzliche Lignan Arctigenin.
