description: Die Methode Photoelektronenbeugung (PED) hat sich in den letzten Jahren zu einer wichtigen und erfolgreichen Methode entwickelt, die die Analyse der Struktur und der chemischen Bindung an Oberflächen und Grenzflächen ermöglicht. Die Erfolge der Methode basieren auf dem engen Wechselspiel von Experiment und Theorie. In der vorliegenden Arbeit werden Beiträge zur winkel- und spinaufgelösten PED vorgestellt, die zum einen aus Fragestellungen im Experiment entstanden und zum anderen neue Erkenntnisse prinzipieller Art darstellen. Die Schwerpunkte der Arbeit sind: (1) Experimentelle und theoretische Entwicklungen der Methode PED. (2) Theorie der Photoelektronenbeugung (Vielfachstreu-Cluster-Modell und Spin-Bahn-Kopplung im Anfangszustand der Elektronen) (3) Strukturbestimmung an Halbleiteroberflächen und Halbleitergrenzflächen. (4) Untersuchungen zum Einfluss von PED auf Spinpolarisation und Dichroismus (Modell der Peakrotation und Symmetriebrechung im zirkularen Dichroismus). (5) PED-Effekte im magnetischer Dichroismus der Winkelverteilung der Photoelektronen.

description: Hintergrund: Wir untersuchten die prophylaktische präoperative Implantation einer intraaortalen Ballonpumpe (IABP) in herzchirurgischen Hochrisikopatienten mit einer additiven EuroSCORE-Summe ≥8. Material und Methoden: Randomisierte Studie mit 104 Patienten, denen prophylaktisch keine IABP (Gruppe A, n=52) oder eine IABP (Gruppe B, n=52) implantiert wurde. Primärer Endpunkt war die 30-Tagessterblichkeit. Ergebnisse: Das mediane Alter der Patienten betrug 74 Jahre und 43% der Patienten waren Frauen. Die 30-Tagessterblichkeit unterschied sich nicht (Gruppe A 17,3% versus Gruppe B 13,4%, p=0,78). Die mediane Klinikaufenthaltsdauer betrug in beiden Gruppen 14 Tage. In Gruppe A benötigten 13 Patienten (21%) intra- und postoperativ eine IABP-Unterstützung. Mediane Beatmungszeit (14 h versus 13 h), medianer Katecholaminbedarf, Häufigkeit eines akuten dialysepflichtigen Nierenversagens (28 versus 18%), kardiale Indizes und Häufigkeit eines „Low-cardiac-output“-Syndroms (26 versus 25%) waren zwischen den Gruppen nicht signifikant verschieden. Schlussfolgerung: Die präoperative prophylaktische IABP-Implantation in EuroSCORE-stratifizierten Patienten ist nicht mit einer reduzierten 30-Tagessterblichkeit assoziiert.
description: Background: We examined the impact of prophylactic IABP insertion in EuroSCORE-stratified high-risk cardiac surgery patients with a score ≥8. Material and methods: A randomized trial with 104 patients either without prophylactic IABP insertion (group A, n=52) or with IABP (group B, n=52) was conducted. The primary endpoint was 30-day mortality. Results: The median age of the patients was 74 years and 43% of participants were females. The 30-day mortality did not differ between group A (17.3%) and group B (13.4%; p=0.78). The median hospital stay was 14 days in both groups. Intra- and postoperative IABP support was required by 13 patients (21%) in group A. The median ventilation time (14 hours versus 13 hours), median catecholamine dose, frequency of dialysis-dependent acute renal failure (28% versus 18%), cardiac indices, and frequency of a low cardiac output syndrome (26% versus 25%) did not significantly differ between groups. Conclusion: Prophylactic preoperative IABP insertion in EuroSCORE-stratified high-risk patients is not associated with decreased 30-day mortality.

description: We present our successful Chandra program designed to identify, with sub-arcsecond accuracy, the X-ray afterglow of the short GRB 111117A, which was discovered by Swift and Fermi. Thanks to our rapid target of opportunity request, Chandra clearly detected the X-ray afterglow, though no optical afterglow was found in deep optical observations. The host galaxy was clearly detected in the optical and near-infrared band, with the best photometric redshift of z=1.31_{-0.23}^{+0.46} (90% confidence), making it one of the highest known short GRB redshifts. Furthermore, we see an offset of 1.0 +- 0.2 arcseconds, which corresponds to 8.4 +- 1.7 kpc, between the host and the afterglow position. We discuss the importance of using Chandra for obtaining sub-arcsecond X-ray localizations of short GRB afterglows to study GRB environments.

description: Das Ziel dieser Arbeit war es, anhand der bundesweiten DRG-Statistik der Jahre 2005 und 2006 bevölkerungsbezogene Humeruskopfprothese (HA) Raten und Totalendoprothese (TSA) Raten zu vergleichen. HA (N=11 435) und TSA (N=5 134) wurden identifiziert und altersspezifische, altersstandardisierte und bundeslandspezifische HA- und TSA-Raten ermittelt. Die altersstandardisierten HA-Raten betrugen 3,6 pro 100 000 Personenjahre (Männer) und 9,3 pro 100 000 Personenjahre (Frauen) und lagen damit deutlich höher als die altersstandardisierten TSA-Raten mit 1,7 pro 100 000 Personenjahre (Männer) und 3,7 pro 100 000 Personenjahre (Frauen). In jedem Altersbereich lagen die HA-Raten über den TSA-Raten. Die bundeslandspezifischen Schulterendoprothesen-Raten zeigten erhebliche Schwankungen vor allem bei der TSA. Die bestehenden zum Teil deutlichen regionalen Unterschiede der Schulterendoprothese-Raten deuten auf eine unterschiedlich starke klinische Etablierung besonders bei der Anwendung der TSA hin.
description: The aim of this study was to provide nationwide hemiarthroplasty (HA) rates and total shoulder arthroplasty (TSA) rates in Germany based on the DRG data of the years 2005 and 2006. We included 11 435 HA and 5 134 TSA and calculated age-specific rates, age-standardised rates and regional-specific (German Federal Land - Bundesland) rates. The age-standardised HA rates were 3.6 per 100,000 person years (men) and 9.3 per 100,000 person years (women) and clearly exceeded the age-standardised TSA rates of 1.7 per 100,000 person years (men) and 3.7 per 100,000 person years (women). The age-specific HA rates topped the corresponding age-specific TSA rates. The regional-specific rates fluctuate extensive, particularly in TSA. The large regional differences in shoulder arthroplasty rates could due to differences in the clinical handling of shoulder arthroplasty, particularly in TSA.

description: Ziel dieser Arbeit war es, ein Schienungskonzept zur Versorgung dentoalveolärer Verletzungen zu erarbeiten. Grundlage waren dabei die aktuellen Erkenntnisse aus der Literatur sowie eigene Untersuchungen. Mit Hilfe einer retrospektiven Auswertung der traumatologischen Patienten unserer Klinik aus dem Zeitraum von 1995-1999 wurde festgestellt, dass durchschnittlich 239 Patienten mit traumatisch bedingten Schäden der Zähne und zahnumgebenden Gewebe im Jahr behandelt wurden. Insgesamt 2232 Verletzungen bedurften einer Schienungstherapie, wobei rigide Schienungsverfahren im Untersuchungszeitraum dominierten. Basierend auf den Erkenntnissen der Literatur wurden eine flexible und eine rigide Draht-Komposit-Schienenvariante entwickelt und in vitro einer Rigiditätsuntersuchung unterzogen. Im Rahmen einer prospektiven klinischen Studie wurden diese beiden Draht-Komposit-Schienen indikationsbezogen für die Behandlung dentoalveolärer Verletzungen eingesetzt. Der Ausgangsbefund sowie das Therapieergebnis wurden durch einen Verletzungs- sowie Heilungsindex, welche auf der Beurteilung der Gewebe Zahnhartsubstanz, Endodont, Parodont, Alveolarknochen und Gingiva basieren, einheitlich bewertet. Der kombinierte Einsatz dieser Indices ermöglichte eine Einschätzung der Prognose sowie der Therapieergebnisse. Die guten Heilungsergebnisse, der Tragekomfort für den Patienten und die leichte Anwendbarkeit empfehlen die vorgestellten Schienungsvarianten sowohl für die studentische Ausbildung, als auch für die zahnärztliche Praxis.
description: The aim of this work was to develop a treatment plan for dentoalveolar trauma, based on the current literature and own investigations. A retrospective evaluation of the traumatological patients of our clinik over the period from 1995 to 1999 was performed. An avarage of 239 patients per year were treated after traumatic injuries of teeth. 2232 dental traumas have required a splinting therapie. Rigid splintig methods were dominating. Two wire-composite-splints were developed and an experimental model was constructed to test the rigidity of this splints. One splint was rigid and the other one was flexibel. In a clinical trial both splintes were used in treatment of dentoalveolar trauma in its spezial indications. To describe the inital condition after tooth injurie and for the assessment of the healing results a scorig system was used. The scoring system diagnoses the tissues involved in anterior tooth trauma independently of each other. This system allowes prognosis for any injured tooth and is used to compare healing results. The good healing results, the comfort for the patients and the better application recommends this two splinting methods and the traetment plan for use in dental practice and for student education.

description: This paper presents a new simple design of an integrated driver using a multilevel MMIC technology that can be used to operate a NRZ (No Return to Zero of digits) two, four or eight phase shift keying direct modulator. It can be fed by any digital signals featuring any low level (VOutput Low) between 0 V and 0.5 V and a high level (VOutput High) between 2.5 V and 8 V. It therefore provides a full compatibility with most usual logic families. An MMIC featuring a K-band (17.5 to 21.5 GHz) Bi-Phase Shift Keying modulator (BPSK) along with the proposed driver has been designed. The measured performances are : 6° maximum phase error and 1.1 dB maximum amplitude error over the full 4 GHz bandwidth.

description: We experimentally demonstrated an alternative approach of invisibility cloaking that can combine technical advantages of all current major cloaking strategies in a unified manner and thus can solve bottlenecks of individual strategies. A broadband cylindrical invisibility cloak in free space is designed based on scattering cancellation (the approach of previous plasmonic cloaking), and implemented with anisotropic metamaterials (a fundamental property of singular-transformation cloaks). Particularly, non-superluminal propagation of electromagnetic waves, a superior advantage of non-Euclidian-transformation cloaks constructed with complex branch cuts, is inherited in this design, and thus is the reason of its relatively broad bandwidth. This demonstration provides the possibility for future practical implementation of cloaking devices at large scales in free space.

description: Although in late 1918 countries of East Central Europe had different forms of government and military situations, they all faced similar social problems. First, the wartime ethnicization reached its peak during the phase of imperial collapse in Russia and Austria-Hungary. Second, social conflict intensified, taking increasingly violent forms. Consequently, the newly created states were confronted with a massive deficit of legitimacy. Instability lasted until the early 1920s.

Die vorliegende Arbeit untersucht die Vernetzung von Schule und Universität mit dem Schwerpunkt der Förderung von mathematisch interessierten Schülerinnen und Schülern. Dies erfolgte zunächst durch die Entwicklung einer Arbeitsdefinition zur „Vernetzung von Schule und Universität“ und einer Bestandsaufnahme aktueller Vernetzungsansätze von Schule und Universität im Bereich der Mathematik. Auf dieser Basis wurde ein konzeptioneller Vernetzungsansatz von Schule und Universität mit dem Schwerpunkt der Förderung von mathematisch interessierten Schülerinnen und Schülern herausgearbeitet, welcher den Aspekt gegenseitig inspirierender Zusammenarbeit betont und in einer qualitativen Fallstudie über einen längerfristigen Zeitraum exploriert wurde.
description: The concept of networks between schools and universities in mathematics has been particularly promoted during the last decade as a way of promoting students. This dissertation examines networks between schools and universities with a priority focus on promoting mathematically interested students. This was at first carried out by the development of an operational definition of „networks between schools and universities“ and the inventory of current networking approaches of schools and universities in mathematics. On that basis, a conceptual networking approach of schools and universities with a priority focus on promoting mathematically interested students was developed, which emphasises the aspect of mutual inspiration and was explored in a quality case study.

description: The GaAs MESFET is widely used in high speed digital transmission. But the frequency dispersion of both transconductance and output conductance, mainly due to traps, often penalizes the use of these devices in circuit applications (1). In the time domain these parasitic effects lead to a distorsion of the transmitted pulse and to the shift of the logic levels. GaAs P-HEMTs are known to exhibit less distorsion and gate lag effects. InP HFETs are also susceptible to drain/gate lag effects (2). We report on comparative measurements on GaAs MESFET, GaAs P-HEMT and InP HFET in order to gain a better understanding of the role of traps in InP HFETs.
Zum Tat-abhängigen Proteintransport an der Thylakoidmembran - Membraninteraktion, Rezeptorbindung und Translokation des chimären 16/23 Proteins

description: Der Tat-abhängige Proteintransportweg vermittelt die Translokation von gefalteten Proteinen in bzw. über die Thylakoidmembran. Ermöglicht wird dies durch eine membranständige Tat-Translokase, bestehend aus den Proteinen TatA, TatB und TatC. Während TatB und TatC einen Rezeptorkomplex zur Bindung von Tat-Substraten bilden, vermittelt TatA deren Translokation. Mittels des chimären Tat-Substratproteins 16/23 ist es möglich, die Membraninteraktion, die Rezeptorbindung und die Translokation separat voneinander untersuchen. Ziel dieser Arbeit war es weitere Kenntnisse über die zugrunde liegenden Mechanismen dieser Teilschritte zu erlangen. Es zeigte sich, dass an der Membranbindung zwar das 23 kDa Passagierprotein beteiligt ist, dieser Schritt aber nicht essentiell für den Tat-abhängigen Transport des Substratproteins ist. Darüber hinaus wurde deutlich, dass C-terminale Verkürzungen des Passagierproteins einen Einfluss auf die Rezeptorbindung und damit einhergehend auch auf die Transportrate des Substratproteins haben. Zudem war es erstmals möglich den TatA-Bedarf für die Membrantranslokation des 16/23 Proteins zu quantifizieren.
description: The Tat-dependent protein transport pathway promotes the translocation of folded proteins in or across the thylakoid membrane. This is enabled by a membrane-bound Tat-translocase consisting of TatA, TatB, and TatC. While TatB and TatC form a substrate binding receptor complex, TatA promotes translocation of the substrate. Using the chimeric Tat-substrate protein 16/23, the distinct steps of membrane interaction, receptor binding, and translocation can be examined separately of each other. It was the aim of this work to gain further knowledge about the underlying mechanisms of these processes. It turned out that, even though the 23 kDa passenger protein is involved in membrane binding, this step is not essential for Tat-dependent transport of the substrate protein. Furthermore, it was proven that C-terminal truncations of the passenger protein have effects on the receptor binding and thus also on the transport rate of the substrate protein. Moreover, for the first time the amount of TatA, which is required to promote the membrane translocation of the 16/23 protein, could be quantified.

Identification and functional evaluation of abscisic acid UDP-Glucosyltransferase gene candidates in grapevine (vitis vinifera).
Creators: name: Liu, Keyu
Publisher: name: University of British Columbia
Year: 2013

description: In grape and some other fruits used for wine making, abscisic acid (ABA) has been demonstrated to be involved in regulating fruit development. ABA metabolism has been characterized in the model plant Arabidopsis thaliana and shown to involve at least three catabolic pathways that inactivate free ABA. Abscisic acid UDP-Glycosyltransferase (ABA-UGT), a member of Glycosyltransferase (GTs) protein family 1, is a key enzyme in the abscisic acid metabolism which leads to the deactivation of ABA. ABA-UGT catalyzes the glucosylation process from abscisic acid to its conjugated metabolite abscisic acid glucose ester (ABA-GE) in planta. ABA-GE is a terminal product of the ABA metabolic pathway and does not appear to have any biological function. Thus, manipulation of ABA-UGT in wine-making fruits will offer a possibility to control the metabolism of ABA with the potential to optimize the ripening of fruit. In this study, genomic and biochemical approaches were used to attempt to identify ABA-UGT in Vitis vinifera, the European grapevine species most widely used in wine making. The identification of ABA-UGT can be a foundation for further research about how ABA is involved in the fruit development and other processes in grapevine.

description: This paper is the result of an extensive investigation on the large signal dynamic behaviour (Pulsed I/V) of unipolar GaAs devices, in the overall I/V plane, when varying the incident optical input power. We have observed a hyperbolic dependence with the gate voltage along with a quasi -logarithmic dependence with the optical power. An empirical equation has been developed in order to take into account both effects, and the successive simulations show a very good agreement with the experimental data for different foundries and technological process.
Theory of electron-phonon superconductivity: Does retardation really lead to a small Coulomb pseudopotential?

description: The theory of electron-phonon superconductivity depends on retardation drastically reducing effects of the strong Coulomb repulsion. The standard theory only treats the lowest order diagram, which is an uncontrolled approximation. We study retardation in the Hubbard-Holstein model in a controlled way using perturbation theory and dynamical mean-field theory. We calculate analytically second order results for the pseudopotential $μ^*$ and demonstrate the validity up to intermediate couplings by comparison with non-perturbative results. Retardation effects are still operative, but less efficient, leading to somewhat larger values of $μ^*$. Therefore, our theory can help to understand situations where the standard theory yields overestimates for $T_c$.

description: The influence of local moment magnetism on the boron isotope effect of T$_c$ was studied on single crystals of ErNi$_2$B$_2$C. Values of the partial isotope effect exponent of $α_B$=0.10$\pm$0.02 and $α_B$=0.10$\pm$0.04 were obtained based on two different criteria applied to extract $T_c$. No significant change in the partial isotope effect exponent compared to the ones obtained for LuNi$_2$B$_2$C was observed. Based on this result we conclude that pair-breaking due to the Er local magnetic moment appears to have no detectable influence on boron isotope effect of T$_c$.

Vertical Product Differentiation, Network Competition and Regulation of Connectivity

Subjects: SECS-P/01 Economia politica

description: In this paper competition between two network firms is analysed under two alternative regulatory regimes: a global connectivity regulation (GCR) and an efficient component pricing regulation (ECPRe). Whereas a GCR imposes a full quality of reciprocal interconnection, firms will choose vertical product differentiation in order to lower price competition, while under a ECPRe they will choose the maximum level of services quality and a global degradation of connectivity. Hence firms’ decisions about whether or not vertically differentiate products seems to be, at least partially, related to regulatory rules imposed on the market.

Als Fazit muss die hohe Verantwortung der Gutachter betont werden.
description: The objective of this study was the analysis of the processes associated with the proceedings in dental prosthetics cases, with particular consideration of the influence of expert assessment on judicial decisions. 94 opinions of court-appointed experts were examined along with the corresponding procedural and judgement reports. The Regional Courts were the main bodies ordering expert opinions at 52.1 %. In 89 % of procedures, the experts prepared opinions of deficiency as an assessment of the dental prostheses already installed. 73.4 % of proceedings were instituted by patients, of which 62.3 % were women. Injury awards and compensation were the main causes of action at 46 % and the average length of proceedings was 21.9 months. Most expert opinions (53.3 %) were given on fixed dental prosthetics, followed by combined fixed-removable prosthetics at 38.3 %. The experts assessed planned prosthetics as 80 % faultless, and finished prosthetics as possibly about one-third each as flawless, requiring reworking or to be newly made. With one exception, in their judgements the judges fully followed the experts’ conclusions with respect to the planned or executed prosthetic care. In conclusion, the high degree of responsibility of the experts must be emphasised.
Differential Oligopoly Games where the Closed-Loop Memoryless and Open-Loop Equilibria Coincide
Creators: name: Cellini, Roberto

description: We illustrate two differential oligopoly games using, respectively, the capital accumulation dynamics à la Nerlove-Arrow, and the capital accumulation dynamics à la Ramsey. We prove that these games benefit from the property that closed-loop memoryless solutions degenerate into open-loop solutions, since the best reply of a generic firm is independent of the rivals’ state variables, which entails that the cross effect from rivals’ states to own controls disappears.

R&D in transport and communication in a Cournot duopoly
Creators: name: Lambertini, Luca

Subjects: SECS-P/01 Economia politica

description: We analyse R&D activity in transport and communication technology (TCRD), in a Cournot duopoly. Transport and communication costs are of the iceberg type, i.e., using up some portion of the product along its path to the final buyer. Firms invest in TCRD to increase the net amount of the product that reaches consumers. A variety of equilibria arise as a result of the different levels of TCRD efficiency. If TCRD’s productivity is high, the game is a prisoner’s dilemma where both firms invest in TCRD. As the efficiency of the TCRD progressively fades we come across first a chicken game and, then, at lower efficiency, a game with an equilibrium in dominant strategies where the profits are at the highest. Social welfare is maximised by market strategies only when TCRD is very efficient.
Advertising in a Differential Game of Spatial Competition

Subjects: SECS-P/01 Economia politica

description: We investigate a dynamic duopoly game with horizontal product differentiation, to show that the standard approach to spatial competition fails to produce a pure strategy equilibrium in prices when treated in a differential game framework. This holds independently of the shape of the transportation cost function. Then, we introduce an endogenous costs associated with the choice of location and characterise the open-loop and closed-loop equilibria of the model, showing that in the closed-loop case firms invest more in product differentiation and less in advertising, than they do in the open-loop setting. This happens because the gains from product differentiation can be more easily internalised than those associated with advertising.
Coherent storage and phase modulation of single hard x-ray photons using nuclear excitons

description: Coherent storage and phase modulation of x-ray single-photon wave packets in resonant scattering of light off nuclei is investigated theoretically. We show that by switching off and on again the magnetic field in the nuclear sample, phase-sensitive storage of photons in the keV regime can be achieved. Corresponding $π$ phase modulation of the stored photon can be accomplished if the retrieving magnetic field is rotated by $180^{\circ}$. The development of such x-ray single-photon control techniques is a first step towards forwarding quantum optics and quantum information to shorter wavelengths and more compact photonic devices.

description: Several mechanical systems are modeled by the static momentum balance for the displacement u coupled with a rate-independent flow rule for some internal variable z. We consider a class of abstract systems of ODEs which have the same structure, albeit in a finite-dimensional setting, and regularize both the static equation and the rate-independent flow rule by adding viscous dissipation terms with coefficients εα and ε, where 00 is a fixed parameter. Therefore for α different from 1 the variables u and z have different relaxation rates. We address the vanishing-viscosity analysis as ε tends to 0 in the viscous system. We prove that, up to a subsequence, (reparameterized) viscous solutions converge to a parameterized curve yielding a Balanced Viscosity solution to the original rate-independent system and providing an accurate description of the system behavior at jumps. We also give a reformulation of the notion of Balanced Viscosity solution in terms of a system of subdifferential inclusions, showing that the viscosity in u and the one in z are involved in the jump dynamics in different ways, according to whether α >1, α=1, or 0

description: Die vorliegende Dissertation beschäftigt sich mit der Reform des deutschen Medizinstudiums 1901. Es werden die Ursachen, die zu den Veränderungen im Medizinstudium führten, erörtert, der Weg der Reform erläutert und die Ergebnisse der Studienreform aufgezeigt. Eine besondere Rolle bei der Durchführung der Studienreform spielte Friedrich Theodor Althoff, der von 1882 bis 1907 im preußischen Kultusministerium für die Hochschulpolitik verantwortlich war. Nach über zehnjähriger Bearbeitungszeit konnte die Reform des deutschen Medizinstudiums am 28.05.1901 abgeschlossen und in Kraft gesetzt werden. Wesentliche Neuerungen, die sich aus der Reform für die Studenten ergaben, waren die Verlängerung des Studiums auf zehn Semester, die Einbeziehung neuer Fachrichtungen in den Studienplan und die Einführung eines Praktischen Jahres. Die Studienzulassung dehnte sich neben Abiturienten der humanistischen Gymnasien auf Abgänger der Realgymnasien aus. Mit der neuen Prüfungsordnung war eine erhebliche Erweiterung des wissenschaftlichen und praktischen Unterrichts an den medizinischen Fakultäten verbunden.

Incentive-Based Lending Capacity, Competition and Regulation in Banking
Creators: name: Chiesa, Gabriella
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2000
Subjects: SECS-P/01 Economia politica

description: This paper studies moral hazard in banking due to delegated monitoring in an environment of aggregate risk and examines its implications for credit market equilibrium and regulation, in a model where banks are price competitors for loans and deposits. It provides a rationale for an incentive-based lending capacity positively linked to the bank’s capital and profit margin, for an oligopolistic market structure wherever banks have market power, and for capital requirements. Social-welfare-maximizing capital requirements are lowered in recessions, are higher the more fragmented the banking sector, and are increased when anti-competitive measures are removed. In equilibrium banks earn excessive profits and credit may be rationed.
Dynamic Duopoly with Vertical Differentiation

description: I analyse a differential game where firms, through capital accumulation over time, supply vertically differentiated goods. This proves that several results obtained by the static approach are not robust. I show that (i) the sustainability of the duopoly regime is conditional upon the level of firms’ R&D investments; (ii) there are quality ranges where the low quality firm invests more than the high quality firm; (ii) there are quality ranges where the low quality firm’s profits are larger than the high quality firm’s.

description: Dark matter with mass below about a GeV is essentially unobservable in conventional direct detection experiments. However, newly proposed technology will allow the detection of single electron events in semiconductor materials with significantly lowered thresholds. This would allow detection of dark matter as light as an MeV in mass. Compared to other detection technologies, semiconductors allow enhanced sensitivity because of their low ionization energy around an eV. Such detectors would be particularly sensitive to dark matter with electric and magnetic dipole moments, with a reach many orders of magnitude beyond current bounds. Observable dipole moment interactions can be generated by new particles with masses as great as 1000 TeV, providing a window to scales beyond the reach of current colliders.

12-Hydroxystearic acid-based in situ forming organogels - development and characterization
Creators: name: Windorf, Martin

Subjects: subject: 615

description: In dieser Arbeit wurden innovative In Situ Forming Organogels entwickelt. Diese bestehen zum Großteil aus Erdnussöl sowie einem niedermolekularen Gelbildner (12-Hydroxystearinsäure) und einer geringen Menge eines wassermischbaren, organischen Lösungsmittels (N-Methyl-2-pyrrolidon). Die Formulierung lässt sich mittels schmaler, patientenfreundlicher Kanülen und geringem Kraftaufwand applizieren. Nach Injektion dieser öligen Lösung diffundiert das organische Lösungsmittel in wenigen Stunden in das umliegende wässrige Medium bzw. Gewebe. Folglich präzipitiert der Gelbildner im Öl, geliert dieses und schließt den Wirkstoff mit ein. Je nach Konzentration des Gelbildners wurden die festen Gel-Depots in vitro mittels Lipase innerhalb von 1-3 Monaten schichtweise und rückstandslos abgebaut. Erdnussöl und Gelbildner zeigten keinerlei Zelltoxizität, wohingegen das Lösungsmittel eine konzentrations- und expositionszeitabhängige Beeinträchtigung der Zellen aufwies. In vivo ergaben MRT- und Ultraschall-Untersuchungen einen rückstandlosen Abbau der Depots innerhalb von 3-5 Monaten. Wirkstoff-Therapiestudien an Mäusen zeigten eine gute Verträglichkeit der entwickelten Formulierungen und eine kontrollierte Freisetzung über 5 Monate.
description: In this work, innovative In Situ Forming Organogels have been developed. They consist for the largest part of peanut oil and a low molecular weight organogelator (12-hydroxystearic acid) as well as a small amount of a water-miscible organic solvent (N-methyl-2-pyrrolidone). The formulation can be applied by means of narrow, patient-friendly cannulas and minimal effort. After injection of the oily solution, the organic solvent diffuses into the surrounding aqueous medium or tissue within a few hours. Consequently, the organogelator precipitates and gels the oil and simultaneously imbeds the active pharmaceutical ingredient (API). Depending on the concentration of the organogelator, the solid depots were degraded in vitro by means of lipase within a period of 1-3 months layer-by-layer and without residue. Peanut oil and organogelator showed no cell toxicity, whereas the solvent had a concentration and exposure-time-dependent impairment on the cells. In vivo, MRI and ultrasound examinations have resulted in a complete degradation of the depots within 3-5 months. Drug therapies in mice showed good compatibility of the developed formulations and a controlled release over 5 months.
