description: The optical counterpart of the neutron star X-ray binary and well known X-ray burster, 4U 1636-53 (= 4U 1636-536 = V801 Ara) has been well studied for three decades. However to date, no infrared studies have been reported. Our aims are to identify and investigate the near-infrared (NIR) counterpart of 4U 1636-53. We present deep, K_s-band (2.2 micron) imaging of the region of 4U 1636-53 taken with the Infrared Spectrometer And Array Camera (ISAAC) on the Very Large Telescope. Archival optical and UV data are used to infer the 0.2-2.2 micron spectral energy distribution (SED). One star is located at coordinates alpha =16:40:55.57, delta =-53:45:05.2 (J2000; 1 sigma positional uncertainty of ~ 0.3 arcsec) which is consistent with the known optical position of 4U 1636-53; its magnitude is K_s = 16.14 +- 0.12. This star is also detected in the 2MASS survey in J-band and has a magnitude of J = 16.65 +- 0.22. Under the assumption that the persistent emission is largely unvarying, the 0.4-2.2 micron de-reddened SED can be described by a power law; F_nu propto nu^(1.5 +- 0.3), with some possible curvature (F_nu propto nu^(<= 1.5)) at 0.2-0.4 microns. The SED can be approximated by a blackbody of temperature ~ 27 000 K. This is typical for an active low-mass X-ray binary, and the emission can be explained by the outer regions of a (likely irradiated) accretion disc. We therefore interpret this K_s-band star as the NIR counterpart.

Perú es el país con más especies endémicas de odonatos en los andes tropicales, siendo Madre de Dios un área de alto endemismo dentro de él. Sin embargo, la mayoría de especies de libélulas conocidas para Perú poseen datos insuficientes para determinar su estado de conservación. El objetivo de este estudio fue determinar si la abundancia de libélulas varía según el porte–herbáceo o arbustivo– de las plantas o con la abundancia de insectos (considerado como fuente de alimento) que se encuentran a las orillas de la cocha Cashu. Se establecieron 21 zonas de muestro (9 de porte arbustivo y 12 de porte herbáceo) en el sector sur de la cocha de manera aleatoria separadas por, al menos, 20 metros. Se reportaron el porte vegetativo del borde del lago, porcentaje de nubosidad, temperatura, abundancia de odonatos y  de insectos. La abundancia de libélulas se determinó mediante conteos visuales durante 15 minutos. Para la de insectos, se colectó con una red aérea por 5 minutos. El periodo de evaluación fue del 23 de octubre al 16 de noviembre del 2017. Se evaluó en tres bloques de tiempo: 09:00-11:00h,  11:00-13:00h y 13:00-15:00h. Se realizó un GLMM [Abundancia de libélula ~ Abundancia de insectos + Porte + Temperatura + %Nubosidad + (1|Tiempo) + (1|Zona)]. No se encontraron diferencias significativas de la abundancia de odonatos entre los tipos de porte vegetativo; mientras que si se presentaron diferencias con la temperatura y la abundancia de insectos. Estas variables presentaron valores similares para ambos tipos de porte vegetativo. Ello explicaría la similitud entre la abundancia de libélulas de las zonas con vegetación arbustiva y herbácea. No obstante, se presentaron diferencias en la abundancia de algunos morfotipos de libélulas, lo que sugeriría que existe un recambio de especies dentro del ensamblaje de las mismas.

description: In 2006, the Earth Institute at Columbia University launched the Millennium Cities Initiative (MCI), an urban counterpart to the Millennium Villages Project (MVP), to assist nine mid-sized cities across subSaharan Africa in achieving the Millennium Development Goals (MDGs). MCI provides research and policy analysis in order to attract foreign direct investment (FDI) to the cities.  Using the investment evaluation framework described in Section I, the authors identified the textile manufacturing sector as having considerable investment potential in Malawi, distinguished by higher impact and feasibility. Investment in this sector is expected to have high positive impacts on employment and productivity, as well as high feasibility measured by demand, supply, enabling market and profitability factors. In addition to textile manufacturing, which is the sole high feasibility-impact sector, the authors identified five medium feasibility-impact sectors. These investment opportunities include the following agricultural value-added products: cassava processing, pigeon pea processing, chili processing, groundnuts processing and macadamia nut processing. Having identified opportunities for investment, the authors also evaluated constraints hampering the growth of each industry and set forth recommendations for MCI with a view to encouraging FDI in the High Feasibility-Impact sectors and alleviating constraints that hamper growth in these sectors.

description: The rapid spread of infectious disease outbreaks, such as the COVID-19 pandemic, once again emphasized the importance of deploying the potentials of biosensing technologies, as a key tool for controlling further transmission. Although the gold standard technique, Polymerase Chain Reaction (PCR), has become swiftly adopted, their limitations ask for more rapid, time-saving, and miniaturized approaches, such as all-in-one portable diagnostic platforms. Depending on the biosensing approach, the sensing element and the fluid-handling segment are considered as the most important elements of such platforms. As for the sensing methods, electrochemical immunosensing proved to have the sensitivity required for detecting the low amount of target proteins, which is favorable for early-disease detection, only if the surface of the sensor is modified to exhibit a high capacity for specific probe immobilization. Hence, introducing highly receptive surfaces is important for enhancing the sensitivity. For utilizing electrochemical immunosensors in point-of-care devices, the challenge of accommodating all of the conventionally lab-centralized sensing processes into one single chip also requires further research and investigation. To this end, the focus of the present thesis was to introduce an ultrasensitive nano-biosensor based on Zinc Oxide (ZnO) and Reduced Graphene Oxide (rGO) nanocomponents, which could successfully create a highly porous and stable sensing surface. The coated electrodes were functionalized with an L-cysteine cross-linker to provide abundant sources of carboxylic acid functional groups, an essential moiety for antibody immobilization. The morphology, physical and chemical characteristics of the sensing surface were thoroughly analyzed using spectroscopy and microscopy techniques. The electrochemical impedance spectroscopy (EIS) experiments confirmed the functionality of the immunosensor for detecting as low as 21 fg/mL SARS-CoV-2 biomarker, the Nucleocapsid (N-) protein, while it was further used for clinically detecting positive clinical swab samples. The integration of the biosensor into a microfluidic testing kit was also been explored, with a novel redox-contained chip automating all steps of immunosensing in one single kit. The platform successfully operated within 15 min for detecting N-proteins of the nasopharyngeal (NP) swab sample. This electrochemical biosensor integrated within the accompanying microfluidic chip provides a promising perspective towards the realization of a point-of-care platform.

description: This article describes the impact of the Italian electoral reforms of 1993 on the structure of political alliances. The reform, which moved Italy from a pure proportional representation system to a mixed largely majoritarian system, was designed to increase transparency, reduce corruption, limit the number of political parties, and create the conditions for a politics of interests, rather than a politics of influence. Paradoxically, moving to a mixed electoral system had the opposite effect. In this article, the authors demonstrate this impact, by modeling the structure of political alliances at multiple levels (municipal, provincial, and regional) of the Italian polity from 1986 to 2001, from data on roughly 441,000 persons elected to serve in almost 3 million positions.

description: Vergangene Naturkatastrophen zeigen, dass Katastrophenbewältigung ohne Berücksichtigung der Zivilbevölkerung nicht mehr denkbar ist. Sogenannte Spontanhelfende organisieren und koordinieren sich und ihre Hilfe dabei weitestgehend selbstständig. Ihr Zustrom an Einsatzorten hat in der Vergangenheit jedoch zu massiven Überlastungen von Einsatzorten geführt, wodurch offizielles Katastrophenpersonal vor Ort in der Bewältigung ihrer Arbeit durch diese zusätzliche Herausforderung behindert wurde. Die Probleme, die durch den Zustrom an Einsatzorten entstanden sind, waren vor allem auf die unvorhersehbare Natur der Spontanhelfenden und das Fehlen von Katastrophenmanagementwerkzeugen zur Planung und Vorbereitung solcher Szenarien zurückzuführen. Unter Verwendung eines designwissenschaftlichen Forschungsansatzes zielt die Dissertation darauf ab, ein Informationssystem zu entwerfen, zu entwickeln und zu evaluieren, das den Zustrom von Spontanhelfenden an Einsatzorten vorhersagen soll.
description: ePast natural disasters showed that disaster management is no longer conceivable without considering civil participation, i.e., spontaneous volunteers, who predominantly organize and coordinate their help efforts on their own. In this regard, spontaneous volunteers led to, e.g., massive overloads of operating sites, causing official on-site disaster staff to be hampered in their work by this additional challenge. The problems caused by their influx at operating sites were primarily due to the unpredictable nature of spontaneous volunteers and a lack of disaster management tools to plan and train for such scenarios. Following a design science research approach, the dissertation aims to design, develop, and evaluate an information system for predicting the influx of spontaneous volunteers at operating sites. engl.

description: The vacuum expectation value (VEV) of the energy-momentum tensor for a massive fermionic field is investigated in a (2+1)-dimensional conical spacetime in the presence of a circular boundary and an infinitely thin magnetic flux located at the cone apex. The MIT bag boundary condition is assumed on the circle. At the cone apex we consider a special case of boundary conditions for irregular modes, when the MIT bag boundary condition is imposed at a finite radius, which is then taken to zero. The presence of the magnetic flux leads to the Aharonov-Bohm-like effect on the VEV of the energy-momentum tensor. For both exterior and interior regions, the VEV is decomposed into boundary-free and boundary-induced parts. Both these parts are even periodic functions of the magnetic flux with the period equal to the flux quantum. The boundary-free part in the radial stress is equal to the energy density. Near the circle, the boundary-induced part in the VEV dominates and for a massless field the vacuum energy density is negative inside the circle and positive in the exterior region. Various special cases are considered.

Contracts

description: One of the most vexing public policy issues is the extent to which governments should intervene into private contractual relationships. The purpose of this paper is to explore both theoretically and empirically the extent to which such interventions may enhance efficiency. In the case of employment law, economists have traditionally taken the view that intervention, such as protection against wrongful discharge, simply undoes the original intent of the parties to the agreement. We find that both the good faith and the implied contract exceptions to employment at will may enhance employment in occupations characterized by high levels of investment. These results suggest that under the appropriate conditions courts may enhance the operation of a competitive market by setting appropriate default remedies for breach of contract.

description: Using a Monte Carlo method on a lattice model of a vicinal surface with short-range step-step attraction, we show that, at low temperature and near equilibrium, there is an inhibition of the motion of macro-steps. This inhibition leads to a pinning of steps without defects, adsorbates, or impurities (self-pinning of steps). We show that this inhibition of the macro-step motion is caused by faceted steps, which are macro-steps that have a smooth side surface. The faceted steps result from discontinuities in the anisotropic surface tension (the surface free energy per area). The discontinuities are brought into the surface tension by the short-range step-step attraction. The short-range step-step attraction also originates `step-droplets', which are locally merged steps, at higher temperatures. We derive an analytic equation of the surface stiffness tensor for the vicinal surface around the (001) surface. Using the surface stiffness tensor, we show that step-droplets roughen the vicinal surface. Contrary to what we expected, the step-droplets slow down the step velocity due to the diminishment of kinks in the merged steps (smoothing of the merged steps).

The dual role of the desmosomal regulator Plakophilin 3 in cellular adhesion and cell cycle progression

description: Desmosomes are cell structures specialized for cell-to-cell adhesion and are enriched in tissues that are exposed to high mechanical stress such as the skin. While cell type specific expression of desmosomal proteins including the plakophilins (PKPs) has been known for years, little is known about how PKP isoforms affect desmosomal properties and how desmosomal localization of these isoforms is regulated. This thesis shows that epidermal growth factor signaling is important for phosphorylation of PKP3 and its recruitment to the plasma membrane to facilitate desmosome assembly and stabilization of cell-to-cell adhesion. Furthermore, PKP3 acts as a signaling hub modulating the retinoblastoma pathway to promote cell cycle progression. These data demonstrate how signaling pathways balance PKP functions to regulate adhesive strength and allow desmosomes to adapt to their environment in a context-dependent manner. This supports the accurate balance of proliferation and differentiation which is required to control tissue homeostasis in the epidermis.
description: Desmosomen sind Zellstrukturen, die spezialisiert sind auf die Zell-Zell-Adhäsion. Sie kommen vor allem in Geweben vor, die hohen mechanischen Belastungen ausgesetzt sind, wie z. B. der Haut. Während die zelltypspezifische Expression von desmosomalen Proteinen, einschließlich der Plakophiline (PKPs), seit Jahren bekannt ist, gibt es bisher kaum Erkenntnisse über die Beeinflussung der Desmosomen durch PKP-Isoformen oder wie die desmosomale Lokalisation dieser Isoformen reguliert wird. In dieser Arbeit wird gezeigt, dass der epidermale Wachstumsfaktor wichtig ist für die Phosphorylierung von PKP3 und dessen Rekrutierung an die Plasmamembran, wodurch die Desmosomenbildung und die Stabilisierung der Zell-Zell-Adhäsion erleichtert werden. Zudem fungiert PKP3 als Signalknotenpunkt des Retinoblastoma-Protein-Signalwegs, um die Zellzyklusprogression zu fördern. Diese Daten legen dar, wie Signalwege die adhäsive Funktion der PKPs regulieren und wie sie Desmosomen ermöglichen, sich ihrer Umgebung auf kontextabhängige Weise anzupassen. Dies unterstützt das Gleichgewicht von Proliferation und Differenzierung, das für die Kontrolle der Gewebehomöostase in der Epidermis erforderlich ist.

description: Metapelites (metamorphosed shales and mudstones) are an important rock type for interpreting metamorphism. This thesis examines the influence of bulk rock composition on the metamorphism of pelites using a two-pronged approach: (i) analysis of large datasets compiled from the literature and (ii) detailed study of an exceptional metamorphic sequence, the Whetstone Lake area in southeastern Ontario. A database of 3225 published whole rock geochemical analyses from the literature was collated, an order of magnitude greater than any previous. Whilst metapelites worldwide appear geochemically similar, there are many metapelites whose composition lies outside the main cluster. Analysis reveals a decrease in volatile content with increasing metamorphic grade, whilst the proportion of the major elements remains relatively constant. The average metapelite from this database is (wt%): SiO2 = 62.24, TiO2 = 0.94, Al2O3 = 19.88, FeOtotal = 7.32, MnO = 0.13, MgO = 2.68, CaO = 0.92, Na2O = 1.57, K2O = 4.19, and P2O5 = 0.15; the average (± 1σ) XMg = MgO/(MgO+FeOtotal) in moles = 0.40 ± 0.09, and the average XFe3+ = Fe3+/(Fe2+ + Fe3+) in moles is 0.27 ± 0.17. A database of 785 published XFe3+ analyses in metapelitic minerals was collated. Average (± 1σ) XFe3+ values in biotite, white mica, chlorite, and staurolite are 0.11 ± 0.08, 0.55 ± 0.18, 0.08 ± 0.07, and 0.07 ± 0.06, respectively. Whilst there is little variation in XFe3+ with pressure and temperature, there is an increase in XFe3+ in both white mica and biotite from ilmenite- to magnetite- to hematite-bearing samples. Metapelites at Whetstone Lake showcase a diversity of mineral assemblages over a small range of grade, a result of wide differences in bulk composition. Whole rock XMg and XFe3+ exert the greatest control on mineral assemblages, whilst MnO, K2O, and Al2O3 have a secondary influence. The observed mineral assemblages, modal proportions, and mineral compositions from both the XFe3+ database and Whetstone Lake were compared with the predictions of thermodynamic modelling. There is acceptable agreement between predicted and observed mineral assemblages and modes, but consistent discrepancies are found for mineral compositions. These include the overestimation of XMg in garnet, staurolite, and cordierite, overestimation of Ti in staurolite and biotite, underestimation of Si in biotite, and overestimation of Al and underestimation of Fe3+, Fe2+, and Mg in muscovite.

description: Two new alkaloids, phranisines A–B (1–2), along with two known compounds, N-p-Coumaroyl serotonin (3) and N-p-coumaroyl-tryptamine (4), were isolated from the roots of Phragmites australis. The structures of 1–4 were established on the basis of extensive spectroscopic. The absolute configuration of compounds 1–2 were identified through quantum-chemical electronic circular dichroism (ECD) calculation compared with their experimental CD. All the isolated compounds were tested for their cytotoxic activities against HeLa and MCF-7 human cancer cell lines, and compounds 2–4 showed moderate cytotoxic activities against HeLa cell lines with IC50 values ranging from 13.2 to 18.6 μM.
Considering Fluctuation Energy as a Measure of Gyrokinetic Turbulence

description: In gyrokinetic theory there are two quadratic measures of fluctuation energy, left invariant under nonlinear interactions, that constrain the turbulence. The recent work of Plunk and Tatsuno [Phys. Rev. Lett. 106, 165003 (2011)] reported on the novel consequences that this constraint has on the direction and locality of spectral energy transfer. This paper builds on that work. We provide detailed analysis in support of the results of Plunk and Tatsuno but also significantly broaden the scope and use additional methods to address the problem of energy transfer. The perspective taken here is that the fluctuation energies are not merely formal invariants of an idealized model (two-dimensional gyrokinetics) but are general measures of gyrokinetic turbulence, i.e. quantities that can be used to predict the behavior of the turbulence. Though many open questions remain, this paper collects evidence in favor of this perspective by demonstrating in several contexts that constrained spectral energy transfer governs the dynamics.

description: This Geoscience Australia Record 2001/12 is the result of 'The Metallogeny of Australian Proterozoic Granites' project, undertaken by the then Australian Geological Survey Organisation in collaboration with 20 minerals exploration companies. The project was a data driven exercise that asked the simple question: 'Where hydrothermal Au, Cu, Zn, Pb, Sn, W, and Mo mineralisation occurs within 5 kms of the boundaries of Proterozoic Granites, are there any specific characteristics of either the granites and/or their host rocks?' The project compiled data on the mineralogy, geochemistry (~7500 analyses), and age of Proterozoic granites and felsic volcanics, as well as the age and mineralogical composition of sediments within 5 kms of Proterozoic granite boundaries for 20 provinces. The project investigated a spatial association only, and hence it was not considered of major importance if the metals came from the granite or had been leached from the country rock by processes related to granite emplacement. Further, the compilation made every effort to focus on factual data. As the determination of the tectonic setting operating at the time of emplacement of the granites, particularly in rocks as old as Proterozoic, was considered to be highly interpretative, this parameter was not included, due to the data-driven approach of the project. Having compiled the data, a forensic data mining approach was applied. That is, rather than developing a computer derived 'best-fit model' from the data, or taking an existing model and finding areas that matched the prescribed model, a more descriptive approach was tried. Our goal was to investigate the spatial relationship to gain understanding by uncovering patterns and relationships.

description: In summary, a comprehensive investigation of the enzymatic and non-enzymatic oxidative degradation of polyphenols in the presence of amino acids with main focus on the formation of covalent modifications was conducted. A new developed incubation system based on nashi-PPO formed the basis for the successful isolation and structural elucidation of both colorless and colored polyphenol-amino acid intermediates from the enzymatic browning reaction. This system provides a new approach for the investigation of covalent interactions during the enzymatic browning reaction due to its variation possibility of substrates and reaction conditions. The degradation of aspalathin under oxidative conditions delivered new insights to the oxidative degradation pathways of dihydrochalcones, suggesting the intrinsic generation or stabilization of singlet oxygen by phenolic compounds, respectively. All in all, this provides a new approach towards the investigation of structural related phenolic compounds.

Die Etablierung eines neuen enzymatischen Modellinkubationssystems diente als Grundlage für die erfolgreiche Isolierung und Charakterisierung zum Teil farbiger Polyphenol-Aminosäure-Intermediate aus dem Reaktionsverlauf der enzymatischen Bräunungsreaktion und stellt durch die Variationsmöglichkeit der Substrate eine neue Methode zur Untersuchung der kovalenten Interaktionen während der enzymatischen Bräunung dar. Aus dem oxidativen Abbau des Aspalathins wurden Erkenntnisse über einen neuen oxidativen Abbauweg der Dihydrochalkone gewonnen, die auf die mögliche Generierung bzw. Stabilisierung von 1O2 durch Polyphenole schließen lässt und einen neuen Ansatzpunkt für die Untersuchung strukturell ähnlicher Polyphenole bildet.

description: The presence of sulfur in numerous blockbuster drugs, natural products and other medicinally active molecules necessitates the development of efficient methods for the synthesis of carbon-sulfur bonds. Transition metal approaches towards the construction of CS bonds have largely aided in the synthesis of aryl thioethers and related functionalities. However, few examples of catalytic processes demonstrate a tolerance for less reactive aliphatic thiols, leading to a widespread belief of an incompatibility of these substrates in catalytic C-S bond formation. To this end, our group has demonstrated the first examples of rhodium-catalyzed alkyne hydrothiolation processes for the synthesis of alkyl vinyl sulfides. The work detailed in this thesis encompasses the use of Wilkinson’s catalyst in alkyne hydrothiolation for the selective formation of E-linear alkyl and aryl vinyl sulfides. The substrate scope of this process is quite general, tolerating a variety of useful functional groups capable of undergoing further elaboration. Interestingly, alkyne substrates with adjacent heteroatoms undergo a reversal of regioselectivity, often favouring the branched regioisomer relative to the expected E-linear vinyl sulfide. The use of our catalytic alkyne hydrothiolation methodology was applied to the synthesis of a promising cancer chemotherapeutic agent, ON 01910.Na, which shows broad-spectrum activity towards a large number of cancer cell lines. Additionally, the reactivity of aryl and vinyl sulfides was evaluated within the context of vinylogous thioesters capable of undergoing electrocyclizations. The development of a Sonogashira cross-coupling thio-Michael addition sequence allowed for the synthesis of a variety of heteroaromatic substituted vinylogous thioesters. The treatment of these substrates with excess triflic acid proved optimal in facilitating cyclization to thiaindanone-type products, a motif found in molecules with application towards the treatment of neurologic diseases. The observation of interesting skeletal rearrangements suggests a competition between the expected Nazarov cyclization and an intramolecular Friedel-Crafts acylation. Lastly, a series of sidearm-substituted bisoxazolines were synthesized and a preliminary investigation of their coordination chemistry is reported. The application of these complexes towards a variety of asymmetric transformations, including the Nazarov cyclization, is currently ongoing.

description: We demonstrate 3D microwave projection sideband cooling of trapped, neutral atoms. The technique employs state-dependent potentials that enable microwave photons to drive vibration-number reducing transitions. The particular cooling sequence we employ uses minimal spontaneous emission, and works even for relatively weakly bound atoms. We cool 76% of atoms to their 3D vibrational ground states in a site-resolvable 3D optical lattice.

description: Propaganda, combined with censorship, was indubitably one of the genuinely novel features of the First World War. The control over information assumed unprecedented dimensions and was put into effect by governments having recourse also to techniques belonging to the psychology of communication, borrowed from studies in the domain of advertising. This article is chiefly concerned with measures implemented by the government and by the Italian high commands to manage the informational sphere, although it dwells also upon the particular role of war correspondents.

description: The First World War significantly impacted Latin American intellectuals’ view on the subcontinent’s role in the world. The Great War and its repercussions divided society, reinforcing and shaping a renewed nationalism and a growing anti-imperialism in Latin America. Resistance to what was perceived as outsiders’ meddling in the region’s affairs, whether economic, political or cultural, grew. While political sovereignty and cultural distinctness had increasingly been affirmed in the years before 1914, the war reinforced these preexisting tendencies in a variety of ways.

description: The putative scaffold proteins KLCR1 and IQD2 form the basic module of a regulatory multi-protein complex linking the actin- and microtubule cytoskeleton to the plasma membrane. The exact composition and dynamics of this complex, however, remain elusive to date. This thesis aims to characterise the interactions between KLCR1 and IQD2 as well as possible mechanisms of Ca2+-mediated regulation through the archetypal Ca2+-sensor Calmodulin (CaM). It shows for the first time dimerisation of KLCR1 with itself and other KLCRs, and uncovers the modes of interaction between KLCRs and CaMs. Further, KLCR- and CaM-interaction domains in IQD2 are mapped and ternary interactions between KLCR1, IQD2, and CaMs are shown. KLCRs interact with CaMs via the C-terminal helices of their central TPR-domain and likely recruit IQDs through its internal groove. IQD2 binds CaM and KLCRs through its central region. IQD2 putatively recruits KLCRs to CaM for Ca2+-signal transfer at the cytoskeleton-plasma membrane interface.
description: Die mutmaßlichen Gerüstproteine KLCR1 und IQD2 stellen das Kernmodul eines regulatorischen Multiproteinkomplex, der das Aktin- und Miktotubulizytoskelett mit der Plasmamembran verbindet. Die Zusammensetzung und Dynamik dieses Komplexes ist allerdings bislang unbekannt. Diese Arbeit widmet sich der Untersuchung der Interaktionen von KLCR1 und IQD2 sowie möglichen Mechanismen der Ca2+-vermittelten Regulation durch den Ca2+-Sensor Calmodulin (CaM). Die Dimerisierung von KLCR1 mit sich selbst und anderen KLCRs und die Interaktionsmodi von KLCRs mit CaM werden gezeigt. Auch werden Interaktionsdomänen für KLCRs und CaMs in IQD2 kartiert sowie trinäre Interaktionen zwischen KLCR1, IQD2 und CaMs untersucht. KLCRs interagieren mit CaMs durch die C-terminalen Helices ihrer zentralen TPR-Domäne und rekrutieren IQDs vermutlich durch deren innere Krümmung. IQD2 interagiert mit CaM und KLCRs durch seinen zentralen Bereich. Vermutlich rekrutiert IQD2 KLCRs an CaM für Ca2+-Signaltransfer am Übergang zwischen Zytoskelett und Zellmembran.

description: By 1914 the leading states had succumbed to varying degrees of militarism, subordinating other interests to those of the armed forces, yet all were governed by regimes in which the ultimate authority rested with civilian leaders. Civilians led the decisions for war, participated in the development of war aims, and encouraged public attitudes that would accept nothing less than victory. Civilians also accepted wartime restrictions on civil liberties and various versions of martial law. But the general bloodbath ultimately shook public confidence in the military, and in the last half of the war strong civilian leaders emerged to rally the home front in the major Allied countries. Thanks to the ultimate victory of the great powers led by civilians, and the disastrous defeat of a Germany dominated by its leading generals, the war must be judged a victory for civilian over military authority.

description: Die Regeneration des Epithels der Cornea erfolgt über eine Stammzellpopulation im Bereich des Limbus. Um die Stammzellen dort zu lokalisieren und identifizieren sind Stammzellmarker notwendig. Von den bislang untersuchten Markern wird jedoch keiner exklusiv von den limbalen epithelialen Stammzellen exprimiert. Im Rahmen dieser Arbeit sollte der Transkriptionsfaktor IRF8 in einer limbalen epithelialen Zelllinie (hTCEpi) und im Mausauge nachgewiesen werden und erste Hinweise auf dessen mögliche Funktion gewonnen werden. Hierfür wurden histologische, immunhistologische und immunzytochemische Färbungen sowie Tests zur Populationsverdopplungszeit, Differenzierungsversuche und scratch assays durchgeführt. Sowohl im Mausauge als auch in den hTCEpi-Zellen konnte IRF8 nachgewiesen werden. Weiterhin konnte ein möglicher Einfluss von IRF8 auf die Proliferation, der Differenzierung und der Wundheilung gezeigt werden und die Zelllinie als gutes Modell für weitere Untersuchungen etabliert werden.
description: The regeneration of the epithelium of the cornea takes place via a stem cell population in the area of the limbus. In order to localise and identify the stem cells there, stem cell markers are necessary. However, none of the markers investigated so far is exclusively expressed by the limbal epithelial stem cells. In the context of this work, the transcription factor IRF8 should be detected in a limbal epithelial cell line (hTCEpi) and in mouse eyes. Furthermore first indications of its possible function should be obtained. For this purpose, histological, immunohistological and immunocytochemical staining as well as tests for population doubling time, differentiation experiments and scratch assays were performed. IRF8 was detected in the mouse eye as well as in the hTCEpi cells. Furthermore, a possible influence of IRF8 on proliferation, differentiation and wound healing could be shown and the cell line could be established as a good model for further investigations.

description: The heydays of XML have come to a close, and XML finds itself confronted with competitors that represent—in some respects—steps backwards.  In this paper we argue that at this point it is of particular importance to study the history of markup in order to avoid reinventing the wheel, but also to reflect on and possibly re-evaluate design choices in order to advance the state of the art.
