description: Report Summary: The quality of carnation blooms stored in 1/2 or 1 percent oxygen atmospheres was better after 4 to 5 weeks of storage than that of blooms held in air. Low-oxygen atmospheres reduced the incidence of decay in storage. However, the low-oxygen atmosphere in storage was only slightly effective in prolonging the display life. The addition of carbon dioxide to the low-oxygen atmospheres did not increase the storage life of the blooms. Carnation blooms held at 32° F. for 4 to 5 weeks developed petal injury. This injury was greatly reduced at 36°. Respiration rates during storage were reduced in low-oxygen atmospheres, but comparable increase in post-storage life of the blooms was not obtained.
Design and optimization of control primitives for simulated characters

description: Physics-based character motion has the potential of achieving realistic motions without laborious work from artists and without needing to use motion capture data. It has potential applications in film, games and humanoid robotics. However, designing a controller for physics motions is a difficult task. It requires expertise in software engineering and understanding of control methods. Researchers typically develop their own dedicated software framework and invent their own sets of control rules to control physics-based characters. This creates an impediment to the non-expert who wants to create interesting motions and others who want to share and revise motions. In this thesis, we demonstrate that a set of motion primitives that have been developed in recent years constitute effective building blocks for authoring physics-based character motions. These motion primitives are made accessible using an expressive and flexible motion scripting language. The motion language allows a motion designer to create controllers in a text file that can be loaded at runtime. This is intended to simplify motion design, debugging, understanding and sharing. We use this framework to create several interesting 2D planar motions. An optimization framework is integrated that allows the hand-designed motion controller to be optimized for more interesting behaviors, such as a fast prone-to-standing motion. We also develop a state-action compatibility model for adaping controllers to new situations. The state-action compatibility model maintains a hypervolume of compatible states (“situations”) and actions (controllers). It allows queries for compatible actions given a state.

description: C-Zell-Hyperplasien (CCH) können zum Teil als Vorläufer für das medulläre Schilddrüsenkarzinom gewertet werden. Für die hereditäre CCH im Rahmen des MEN-Syndroms kann dieses neoplastische Potenzial als gesichert gelten. Ob allerdings die sporadische CCH wie die hereditäre CCH als Präneoplasie zu betrachten ist, gilt als umstritten. Unklar ist bislang, ob anhand morphologischer Kriterien eine Unterscheidung dieser beiden Läsionen möglich ist. Mit der vorliegenden Studie wird der Versuch unternommen, mittels Lichtmikroskop und digitaler Bildanalyse die morphologischen und morphometrischen Eigenschaften von genetisch eindeutig definierten CCH herauszuarbeiten. Es konnte festgestellt werden, dass morphologisch nicht mit Sicherheit zwischen diesen beiden Läsionen unterschieden werden kann. Morphometrisch unterscheidet sich die hereditäre CCH aufgrund qualitativer und quantitativer Kriterien von der sporadischen CCH. Die peritumorale hereditäre CCH besitzt morphologische und morphometrische Eigenschaften, die mit der von DeLellis et al. beschriebenen Hyperplasie-Karzinom-Sequenz zu vereinbaren sind. Weiterhin konnte festgestellt werden, dass ein Zusammenhang zwischen C-Zell-Quantität und Kalzitonin-Wert besteht.
description: In some cases c-cell hyperplasia can be seen as a precursor lesion of medullary thyroid carcinoma. This neoplastic potential seems to be sure in cases of hereditary c-cell hyperplasia in connection with multiple encocrine neoplasia syndrome (MEN2). But it seems unclear if also the sporadic form of c-cell hyperplasia is a neoplastic condition. Furthermore is unknown if there is a morphologic difference between these two lesions. Intention of this survey was to examine the morphologic and morphometric characteristics of genetically exact defined c-cell hyperplasias by light microscope and digital picture analysis. We could find out that it is not possible to distinguish these two lesions by morphologic characteristics in examination by light microscope. A significant difference between sporadic and hereditary c-cell hyperplasia was asserted in characteristics of cells core and cell nodes diameter examined by digital picture analysis. There seems to be a correlation between the morphologic and morphometric properties of peritumoral hereditary c-cell hyperplasia and the hyperplasia-carcinoma-sequence described by DeLellis et al. Furthermore a correlation between c-cell quantity and calcitonin levels in the blood was asserted.

description: Trait mindfulness confers emotional benefits and encourages skillful emotion regulation, in part because it helps people more deliberately attend to internal experiences and external surroundings. Such heightened attentional control might help skillfully deploy one’s attention towards certain kinds of stimuli, which may in turn help regulate emotions, but this remains unknown. Testing how trait mindful people deploy attention when regulating their emotions could help uncover the specific mechanisms of mindfulness that confer its emotional benefits. The present study aimed to determine whether high trait mindfulness is associated with sustained attention biases to (i.e. longer gaze at) emotional scenes, when all participants are given the emotion regulation goal of staying in a positive mood. To measure this, we used eye tracking to assess selective attention to positive, neutral, and negative photographs. Higher trait mindfulness was associated with both a stronger attention bias for positive (vs. neutral and vs. negative) images, as well as greater success staying in a positive mood during viewing. Surprisingly, this attention bias towards the positive images did not mediate the relationship between mindfulness and maintenance of positive mood. Future work should compare visual attention to other emotion regulation strategies that may maximise positive affect for mindful people.

description: This paper tackles the issue of choosing roles in duopoly games. First, it is
shown that the two necessary (and su¢cient, if both satisfied) conditions for sequential play to emerge at equilibrium are that both leader and follower are at least weakly better off than under simultaneous play. Second, by means of a two-stage game of vertical differentiation, it is shown that if firms can commit to their respective timing decisions, there may exists a case where the leader is not necessarily better off than in the simultaneous equilibrium. Finally, in the absence of any commitment devices, it is proved that the timing choice can be time inconsistent if it is taken before firms proceed to play in both stages taking place in real time.

description: Are asymmetric shocks to output less important for industries which are more open to trade and more technology-intensive? Our results, obtained from a correlation analysis between growth rates of value added in thirteen manufacturing industries in eleven European countries between 1979 and 1990, clearly support the hypothesis. This finding suggests that policies which promote trade and technological innovation may help to decrease the importance of the asymmetric components of the business cycle within European countries.

description: Alexithymia, psychological distress, and posttraumatic stress disorder (PTSD) are highly related constructs. The ongoing debate about the nature and relationship between these constructs is perpetuated by an overreliance on cross-sectional research. We examined the longitudinal interactive relationship between alexithymia, psychological distress, and PTSD. We hypothesised that there is an interactive relationship between the three constructs. Military personnel (N = 1871) completed the Toronto Alexithymia Scale, the Kessler 10 and a PTSD Checklist (PCL-C) at pre-deployment, post-deployment, and at 3–4 years following the post-deployment assessment. We initially tested whether psychological distress is either a moderator or mediator in the relationship between alexithymia and PTSD across the time points. General psychological distress was a partial mediator of total PTSD severity and hyperarousal symptomology at all three time points. Psychological distress fully mediated re-experiencing and avoidance symptomology at all three time points. Our results suggest that those with alexithymia are at longitudinal risk of developing more severe PTSD symptomology and experiencing hyperarousal irrespective of temporal proximity to traumatic exposure. Further, vulnerability to the emergence of re-experiencing and avoidance symptomology for those with alexithymia is increased when one experiences greater distress. Our results show that alexithymia is a persistent risk factor for PTSD symptomology.

description: Determining the value of legumes as soil fertility amendments can be challenging, yet this information is required to guide public policy and to incentivise prescribed landmanagement practices such as conservation agriculture. We use a directional input distance function (DIDF) to estimate shadow prices for symbiotic nitrogen and the technical efficiency for mixed maize-legume production systems in Malawi. The shadow prices reflect the trade-off between fertiliser nitrogen and symbiotic nitrogen required to achieve a given quantity of output. Our results reveal considerable technical inefficiency in the production system. The estimated shadow prices vary across farms and are, on average, higher than the reference price for commercial nitrogen. The results suggest that it would be beneficial to redesign the current pricesupport programs that subsidise chemical fertilisers and indirectly crowd-out organic soil amendments such as legumes.

description: We consider the transitions among intragenerational and alternative intergenerational financing and liquidity risk-sharing mechanisms, in an Overlapping Generations model with endogenous levels of long-lived investments. The existence and characterization of a Self-Sustaining Mechanism, stable across generations, are established. The long-run equilibrium outcome, in a Proposal Game across generations, is shown to depend on the risk-aversion and propensity for early liquidity needs of the agents.

description: Scopo di questo lavoro è quello di indagare la relazione fra dinamica della R&S e dinamica delle esportazioni nei quattro principali paesi dell'Unione Europea: Francia, Germania, Italia e Regno Unito. La stima di un modello panel a effetti fissi (Least Squares Dummy Variables) per l'industria manifatturiera nel suo complesso e per quattordici settori all'interno di questa in riferimento al periodo 1981-92 evidenzia una relazione positiva e significativa tra variazione della quota di R&S di ciascun paese considerato sulla R&S totale dei paesi OCSE e variazione della quota di esportazioni di ognuno di essi sulle esportazioni totali dei paesi OCSE. In particolare, questa relazione è più forte nelle industrie dei Mezzi di trasporto, dei Prodotti chimici e farmaceutici, dei Prodotti alimentari, bevande e tabacchi, della Carta, stampa e editoria. La relazione è invece non significativa nel caso dell'industria dei Prodotti, tessili, dell'abbigliamento e delle calzature. Alla luce di questa evidenza, trova conferma l'ipotesi secondo la quale il vantaggio/svantaggio competitivo delle nazioni è associato in gran parte delle industrie alla loro capacità innovativa.
The purpose is to explain the relation between the dynamics of R&D expenditures and that of exports in the four largest EU countries: France, Germany, Italy, and United Kingdom. Estimation of a fixed effects (Least Squares Dummy Variable) panel model for manufacturing as a whole and for fourteen (two digit) industries in manufacturing over the 1981-1992 period points out a positive and significant relation between variation in the share of R&D by each of the relevant countries on total R&D by all OECD countries and variation in the share of export by each of the relevant countries on total exports by OECD countries. In particular, this relation is stronger in Motor vehicles & equipment, Chemicals & pharmaceuticals, Mechanical engineering, Food, beverages & tobacco, paper & printing, whereas it turns out to be of scant significance for Textiles, clothing & footwear. In the light of these findings, further support is forthcoming to the hypothesis that the competitive advantage/disadvantage of nations is strongly connected to their innovative capability.

description: By direct calculations of matrix form of super Jacobi and mixed super Jacobi identities which are obtained from adjoint representation, and using the automorphism supergroup of the gl(1|1) Lie superalgebra, we determine and classify all gl(1|1) Lie superbialgebras. Then, by calculating their classical r-matrices, the gl(1j1) coboundary Lie superbialgebras and their types (triangular, quasi-triangular or factorizable) are determined, furthermore in this way super Poisson structures on the GL(1|1) Lie supergroup are obtained. Also, we classify Drinfeld superdoubles based on the gl(1|1) as a theorem. Afterwards, as a physical application of the coboundary Lie superbialgebras, we construct a new integrable system on the homogeneous superspace OSp(1|2)/U(1). Finally, we make use of the Lyakhovsky and Mudrov formalism in order to build up the deformed gl(1|1) Lie superalgebra related to all gl(1|1) coboundary Lie superbialgebras. For one case, the quantization at the supergroup level is also provided, including its quantum R-matrix.

description: The issue of timing is addressed in a game between managerial firms. The choice over timing can be taken either by managers or by entrepreneurs. It is shown that (i) delegation drastically modifies the owners' preferences concerning the distribution of roles, as compared to the setting where firms act as pure profit-maximizers; and (ii) the ability of moving first in the market game entails that, at least observationally, the owner of the leading firm prefers not to delegate. I show that the choice of the timing by managers entails the same profit owners would achieve by specifying the timing in the delegation contract.

description: It is clear that Australian governments will provide assistance to farmers in drought, which is a rational political judgement supported by recent survey work suggesting strongly the pervasive existence among voters of agrarian sentiment. In this context, a reasonable question relates to what forms of assistance are most equitable for taxpayers and also have desirable properties for farm businesses. In this study it is argued that traditional and current approaches to drought assistance are not equitable and do not provide sufficient protection to farmers from default and thus insolvency risk. But there is an instrument available to government which can be designed to minimise taxpayer subsidies while at the same time delivering insurance for farmers against default: a Revenue Contingent Loan (RCL). Following the principles inherent in the Higher Education Contribution Scheme, a RCL is financial assistance repaid contingent on a farm’s capacity to pay, meaning that loan defaults can be avoided. We model the revenue streams associated with a hypothetical loan of this type and illustrate the advantages for a farm business of these kinds of debt.

description: We characterise the interplay between firms' decisions in product development, be it joint or independent, and their ensuing repeated price behaviour, either collusive or Bertrand-Nash. Firms face a choice between participating in a joint venture inventing a single product, and in independent ventures developing their respective products which can be either horizontally or vertically differentiated. We prove that joint product development and the resulting lack of horizontal product differentiation may destabilise collusion, whilst firms' R&D decisions have no bearings on collusive stability in the vertical differentiation setting. We also discover the non-monotone dependence of firms' venture decisions at the development stage upon their intertemporal preferences, as well as upon consumers' willingness to pay.

description: The endogenous choice of timing is discussed in a vertically differentiated duopoly where quality improvement requires a fixed convex cost. The timing decision concerns the quality stage. Using an extended game with observable delay, it is shown that only simultaneous equilibria can arise. This puts into question the ability of Stackelberg games to describe the entry process.

description: We show that polar actions of cohomogeneity two on simple compact Lie groups of higher rank, endowed with a biinvariant Riemannian metric, are hyperpolar. Combining this with a recent result of the second-named author, we are able to prove that polar actions induced by reductive algebraic subgroups in the isometry group of an irreducible Riemannian symmetric space of higher rank are hyperpolar. In particular, this result affirmatively settles the conjecture that polar actions on irreducible compact symmetric spaces of higher rank are hyperpolar.

description: By restating geometrical optics within the field-theoretical approach, the classical concept of a photon (and, more generally, any elementary excitation) in arbitrary dispersive medium is introduced, and photon properties are calculated unambiguously. In particular, the canonical and kinetic momenta carried by a photon, as well as the two corresponding energy-momentum tensors of a wave, are derived from first principles of Lagrangian mechanics. As an example application of this formalism, the Abraham-Minkowski controversy pertaining to the definitions of these quantities is resolved for linear waves of arbitrary nature, and corrections to the traditional formulas for the photon kinetic energy-momentum are found. Several other applications of axiomatic geometrical optics to electromagnetic waves are also presented.

Le istituzioni sono prodotti di un processo del passato, che però agiscono nel presente e, attraverso le aspettative, influenzano le scelte future. Tra passato presente e futuro agiscono elementi di continuità, che le istituzioni contribuiscono a stabilizzare, ed elementi di rottura che provocano la dinamica ed il cambiamento delle istituzioni stesse. L’armonia ed il conflitto tra regole formali ed informali diventano uno degli aspetti più evidenti di tale dinamismo.

description: Difficulties in various cognitive functions are common observations in people experiencing anxiety. However, limited research has investigated the effects of psychotherapy on abnormal cognitive functioning. This study assessed whether psychotherapy-related reductions of anxiety result in improvements of cognitive functioning as well. Fifty-four participants with high self-reported anxiety, divided into two experimental groups (N = 28 and N = 26), and 27 non-anxious control participants (N = 27) completed a battery of memory tasks and anxiety questionnaires in three consecutive time points. In experimental group 1, participants started systemic family therapy immediately after the first time point, while, in experimental group 2, participants begun the same type of therapy three months later at the second time point. The results showed that, compared to control participants, at the beginning of the experiment, participants in the experimental groups had significantly lower memory performance, along with higher anxiety. Psychotherapy had a beneficial effect on anxiety symptoms and cognitive performance, with significant changes occurring only after intervals of treatments. These results show that psychotherapy is effective not only in reducing anxiety symptoms but on cognitive functioning as well. This improvement might be linked to the release of cognitive resources previously absorbed by worrisome thoughts, facilitated by a heightened protection from interference.

description: Intubation und Extubation führen zum Anstieg von Herzfrequenz und Blutdruck sowie steigenden peri- und postoperativen Komplikationen bei kardial vorbelasteten und kardial gesunden Patienten. Die vorliegende systematische Übersichtsarbeit untersucht die Effektivität von Esmolol zur Reduktion von Herzfrequenz- und Blutdruckanstiegen unter Intubation und Extubation. Hierfür wurden 49 randomisierte kontrollierte Studien mit 3386 Patienten im Vergleich von Esmolol gegen ein Placebo oder ein anderes wirksames Medikament eingeschlossen. Hauptzielkriterium war die maximale Änderung des systolischen- oder des mittleren arteriellen Blutdrucks sowie als Nebenzielkriterien die Herzfrequenz, diastolischer- und mittlerer arterieller Blutdruck, das Herzfrequenz-Blutdruck-Produkt und aufgetretene Nebenwirkungen. Esmolol wies im Vergleich zum Placebo einen signifikanten Vorteil auf. Dieser konnte im Vergleich gegen andere wirksame Medikamente nicht in allen Gruppen bestätigt werden. Die Ergebnisse schreiben Esmolol eine effektive Senkung von Herzfrequenz und Blutdruck mit Reduktion der Gefahr einer kardialen Ischämie zu.
description: Intubation and extubation lead to an increase in heart rate and blood pressure as well as rising peri- and postoperative complications for cardiac prestressed and healthy cardiac patients. The present systematic review examined the effectiveness of Esmolol to reduce the increase in heart rate and heart pressure under intubation and extubation. Therefore, 49 randomized controlled trials involving 3386 patients in the comparison of Esmolol versus a placebo or another active drug were included. Primary outcome was the maximum change of systolic- or mean arterial blood pressure, while heart rate, diastolic- and mean arterial blood pressure, the rate-pressure-product and encountered side effects were the secondary outcomes. Compared to placebo, Esmolol showed a significant advantage. This advantage could not be observed in all groups using other effective drugs. These results show how Esmolol effectively reduces heart rate and blood pressure, while decreasing the risk of cardiac ischemia.

description: It is demonstrated that the coordinates of the fcc-bcc-fluid triple point of various model systems are located in a relatively narrow region, when expressed in terms of the two proper variables, characterizing the softness and strength of the interaction force at the mean interparticle separation. This can be regarded as a consequence of the "corresponding states principle" for strongly interacting particle systems we have put forward recently [S. A. Khrapak, M. Chaudhuri, and G. E. Morfill, J. Chem. Phys. {\bf 134}, 241101 (2011)]. The related possibilities to predict the existence and approximate location of the fcc-bcc-fluid triple point for a wide range of pair interactions with variable softness are illustrated. Relation of the obtained results to experimental studies of complex (dusty) plasmas are briefly discussed.

Mit der vorliegenden systematischen Übersichtsarbeit sollte die Wirksamkeit von Esmolol bei der Behandlung von supraventrikulären Tachyarrhythmien untersucht werden. Dabei lag ein Schwerpunkt auf der antiarrhythmischen bzw. frequenzsenkenden Wirkung von Esmolol. Die Daten von 14 Studien mit 692 Patienten gingen in die Metaanalysen ein. Esmolol ist besser zur Frequenz- als zur Rhythmuskontrolle geeignet. Gegenüber Placebo können eine erhöhte Herzfrequenz und systolischer Blutdruck signifikant gesenkt werden. Im Vergleich zu anderen Medikamenten konnte kein Unterschied zwischen den Gruppen festgestellt werden. Als häufigste Nebenwirkungen unter Esmolol traten Hypotension und Bradykardie auf.
description: Supraventricular tachyarrhythmias, especially atrial fibrillation, are associated with a substantial mortality, morbidity and economic importance. The present systematic review examined the effectiveness of esmolol in the treatment of supraventricular tachyarrhythmias. Altogether 14 trials with 692 patients were included into meta-analysis. Esmolol is more effective to rate control than rhythm control. It has been found that esmolol can effectively reduce increases in heart rate and systolic blood pressure compared to placebo. In comparison to other drugs there were no significant differences. The most prevalent adverse effect during administration of esmolol were hypotension and bradycardia.

description: Using state contingent analysis, we discuss how and why irrigators adapt to alternative water supply signals. Focusing on the timing of water allocations, we explore inherent differences in the demand for water by two key irrigation sectors: annual and perennial producers. The analysis explores the reliability of alternative water property right bundles and how reduced allocations across time influence alternative responses by producers. Our findings are then extended to explore how management strategies could adapt to two possible future drier state types: (i) where an average reduction in water supply is experienced; and (ii) where drought becomes more frequent. The combination of these findings is subsequently used to discuss the role water reform policy plays in dealing with current and future climate scenarios.

description: The purpose of this paper is to show the capabilities of the dual gate transistors for low noise amplification in the millimeter wave range. Single and dual gate 0.12um AlGaAs/InGaAs/GaAs pseudomorphic HEMTs have been designed and realized for this study. On wafer S-parameters have been performed up to 110GHz. The current gain cutoff frequency fT is 70GHz and the maximum available gain is 13dB at 60GHz. A very low minimum noise figure of ldB is obtained with an associated gain of 20dB at 18GHz. Some others good performances are presented.

description: For investigations into the structure of MU, i.e., minimally unsatisfiable clause-sets or conjunctive normal forms, singular DP-reduction is a fundamental tool, applying DP-reduction F -> DP_v(F) in case variable v occurs in one polarity only once. Recall, in general DP_v(F) replaces all clauses containing variable v by their resolvents on v (another name is "variable elimination"). We consider sDP(F), the set of all results of applying singular DP-reduction to F in MU as long as possible, obtaining non-singular F' in MU with the same deficiency, i.e., delta(F') = delta(F). (In general, delta(F) is the difference c(F) - n(F) of the number of clauses and the number of variables.) Our main results are: 1. For all F', F" in sDP(F) we have n(F') = n(F"). 2. If F is saturated (F in SMU), then we have |sDP(F)| = 1. 3. If F is "eventually saturated", that is, sDP(F) <= SMU, then for F', F" in sDP(F) we have F' isomorphic F" (establishing "confluence modulo isomorphism"). The results are obtained by a detailed analysis of singular DP-reduction for F in MU. As an application we obtain that singular DP-reduction for F in MU(2) (i.e., delta(F) = 2) is confluent modulo isomorphism (using the fundamental characterisation of MU(2) by Kleine Buening). The background for these considerations is the general project of the classification of MU in terms of the deficiency.

description: Given the large and increasing bushfire threat to lives and property in Australia, there is a need for economic evaluation of risk mitigation policies that can be implemented by governments and homeowners. Three broad policies applicable for existing at-risk communities are evaluated: expanded use of landscape-scale prescribed fire; home ignition zone treatment (bushfire defence sprinklers); and early evacuation when a bushfire is burning on extreme or catastrophic fire danger days. Early evacuation is the only option that yields net economic benefits relative to existing policy.

description: This paper provides an experimental microwave analysis of performance decrease of interdigitated HEMT's in millimeter wave range as the total gate width increases. The source inductance has been identified as the main reason of the power density decrease for large gate periphery devices. These behaviour has been checked by large signal measurements in Ka band.

description: Let $G$ be a simple algebraic group defined over a finite field of good characteristic, with associated Frobenius endomorphism $F$. In this article we extend an observation of Lusztig, (which gives a numerical relationship between an ordinary character of $G^F$ and its unipotent support), to the case where $Z(G)$ is disconnected. We then use this observation in some applications to the ordinary character theory of $G^F$.

description: Chronische Entzündungen und fibrotische Verkapselung sind Hauptursachen für Implantatversagen. In einem neu entwickelten invitro Makrophagen/ Fibroblasten-Co-Kulturmodell werden pro-inflammatorische und pro-fibrotischen Eigenschaften von Modell-Biomaterialien untersucht. Der zweite Teil der Arbeit zielt darauf ab, die Entzündungsreaktionen von Biomaterialien durch Immobilisierung von Glykosaminoglykanen (GAG) entweder durch physikalische Adsorption unter Verwendung der Layer-by-Layer(LBL) -Technik oder kovalente Bindung mittels der EDC/NHS-Vernetzungschemie zu reduzieren. Es werden drei Arten von GAGs,Hyaluronsäure (HA), Chondroitinsulfat (CS) und Heparin (Hep),verwendet. Die Entzündungsreaktionen sind bei beiden Immobilisierungsmethoden auf jeder GAG-Oberfläche gegenüber den jeweiligen Kontrollen signifikant reduziert. Zudem sind GAG in Multischichten wirksamer als kovalent gebundene GAG, wobei Hep-basierte Multischichten am effektivsten entzündliche Reaktionen reduzieren.
description: Chronic inflammation and fibrotic encapsulation are major causes to implant failure. Therefore, first studies are carried outwith a newly developed invitro macrophage/fibroblast co-culture model to investigate the pro-inflammatory and pro-fibrotic potentials of model biomaterials. The second part of the thesis aims to reduce the inflammatory responses of biomaterials through glycosaminoglycan (GAG) immobilization by either physical adsorption using the layer-by-layer (LBL) technique or covalent bonding using EDC/NHS cross-linking chemistry. Three types of GAGs -hyaluronic acid (HA), chondroitin sulphate (CS), and heparin (Hep)-are used. The inflammatory responses are significantly reduced on each GAG-modified surface at both immobilization techniques in comparison to their respective controls. Additionally, GAG in multilayers are more effective than covalently bound to amino surfaces, with Hep-based multilayers being most effective in resisting all inflammatory reactions.

description: In this paper we present a design methodology for optical receivers based on transimpedance gain stage which reduces the receiver performance sensitivity to the photodiode parameter set. A transimpedance amplifier has been designed following this approach and experimental results are reported which show an improvement in the overall yield of the receiver. The design methodology proposed here has been easily implemented in a microwave simulator.

description: Die vorliegende Dissertation beschreibt die Entwicklung dreidimensionaler Konstrukte (Scaffolds) für die Züchtung von Knochengewebe und deren Charakterisierung. Zwei Schwerpunkte fanden dabei besondere Beachtung. Zum Einen die Einbettung von nanoskaligen Hydroxylapatitpartikeln in eine Matrix aus bioabbaubaren Polymeren und zum Anderen die Etablierung des Benchtop-MRI als Methode für die Evaluation solcher Konstrukte. Verschiedene Strategien der Scaffoldherstellung aus Hydroxylapatit, Kollagen, Chitosan und Polyglykolsäure sind beschrieben. Mittels Röntgenkleinwinkelstreuung und Elektronenmikroskopie konnte deutlich gemacht werden, dass die Scaffolds nanoskaligen Hydroxyl-apatit enthalten. Benchtop-MRI wurde erfolgreich genutzt um (1) Stoffaustauschvorgänge zwischen Scaffolds und umgebenden Kulturmedium zu untersuchen, um (2) die homogene Verteilung der Mineralpartikel in der Matrix zu kontrollieren und (3) die Besiedlung der Konstrukte mit kontrastmittelmarkierten Zellen nichtinvasiv zu verfolgen.
