Die fünf Aspekte der Scharia und die Menschenrechte : die Auslegung des Koran auf neuen Wegen (2008)

Ömer Özsoy

Auch der Koran ist das Werk seiner Zeit; heute kann er nicht ausgelegt werden, ohne seinen historischen Kontext einzubeziehen. Doch noch dominiert ein starres Verständnis des Koran, das den eigentlichen Charakter des religiösen Textes verkennt. Eine kleine, international etablierte Gruppe von islamischen Theologen postuliert eine zeitgenössische innovative Koranexegese, die berücksichtigt, dass die Worte des Koran als eine lebendige Anrede an seine realen Adressaten in Offenbarungszeit und -ort gerichtet waren, nämlich an den Propheten Muhammad, seine Gefährten, die heidnischen Araber, Juden und Christen. So eröffnet sich ein neuer Blick auf die »heilige Schrift« der Muslime.

The wells, subterranean passage, tunnels and water systems of Hagia Sophia in Istanbul (2006)

Çigdem Özkan-Aygün

In November 2005, a survey was begun of the wells in and around Hagia Sophia Church in Istanbul. The long-term goal of the survey is the understanding of the function of the tunnels and the water systems used for Hagia Sophia and its surroundings during the Byzantine and the Ottoman periods. Alternate research methods, such as geophysical research, will be used in future surveys. The 2005 survey examined the channels that run from under the narthex and continue northwards and the southwards of the building as well as channels that run towards the atrium, hippodrome, and garden in the north. The survey resulted in the first photos of the well-bottoms in the history of Hagia Sophia.

Particle ratios from AGS to RHIC in an interacting hadronic model (2004)

Detlef Zschiesche Gebhard Zeeb Kerstin Paech Horst Stöcker Stefan Schramm

Abstract: The measured particle ratios in central heavy-ion collisions at RHIC-BNL are investigated within a chemical and thermal equilibrium chiral SU(3) Ã É approach. The commonly adopted non-interacting gas calculations yield temperatures close to or above the critical temperature for the chiral phase transition, but without taking into account any interactions. In contrast, the chiral SU(3) model predicts temperature and density dependent effective hadron masses and effective chemical potentials in the medium and a transition to a chirally restored phase at high temperatures or chemical potentials. Three different parametrizations of the model, which show different types of phase transition behaviour, are investigated. We show that if a chiral phase transition occured in those collisions, freezing of the relative hadron abundances in the symmetric phase is excluded by the data. Therefore, either very rapid chemical equilibration must occur in the broken phase, or the measured hadron ratios are the outcome of the dynamical symmetry breaking. Furthermore, the extracted chemical freeze-out parameters differ considerably from those obtained in simple non-interacting gas calculations. In particular, the three models yield up to 35 MeV lower temperatures than the free gas approximation. The inmedium masses turn out to differ up to 150 MeV from their vacuum values.

PaCATB, a secreted catalase protecting Podospora anserina against exogenous oxidative stress (2011)

Sandra Zintel Dominik Bernhardt Adelina Rogowska-Wrzesinska Heinz D. Osiewacz

A differential mass spectrometry analysis of secreted proteins from juvenile and senescentPodospora anserina cultures revealed age-related differences in protein profiles. Among other proteins with decreased abundance in the secretome of senescent cultures a catalase, termed PaCATB, was identified. Genetic modulation of the abundance of PaCATB identified differential effects on the phenotype of the corresponding strains. Deletion of PaCatB resulted in decreased resistance, over-expression in increased resistance against hydrogen peroxide. While the lifespan of the genetically modified strains was found to be unaffected under standard growth conditions, increased exogenous hydrogen peroxide stress in the growth medium markedly reduced the lifespan of the PaCatB deletion strain but extended the lifespan of PaCatB over-expressors. Overall our data identify a component of the secretome of P. anserina as a new effective factor to cope with environmental stress, stress that under natural conditions is constantly applied on organisms and influences aging processes.

A novel, non-invasive, online-monitoring, versatile and easy plant-based probe for measuring leaf water status (2008)

Dirk Zimmermann Randolph Reuss Markus Westhoff Petra Geßner Matthias Wolf Bauer Ernst Bamberg Friedrich-Wilhelm Bentrup Ulrich Zimmermann

A high-precision pressure probe is described which allows non-invasive online-monitoring of the water relations of intact leaves. Real-time recording of the leaf water status occurred by data transfer to an Internet server. The leaf patch clamp pressure probe measures the attenuated pressure, Pp, of a leaf patch in response to a constant clamp pressure, Pclamp. Pp is sensed by a miniaturized silicone pressure sensor integrated into the device. The magnitude of Pp is dictated by the transfer function of the leaf, Tf, which is a function of leaf patch volume and ultimately of cell turgor pressure, Pc, as shown theoretically. The power function Tf=f(Pc) theoretically derived was experimentally confirmed by concomitant Pp and Pc measurements on intact leaflets of the liana Tetrastigma voinierianum under greenhouse conditions. Simultaneous Pp recordings on leaflets up to 10 m height above ground demonstrated that changes in Tf induced by Pc changes due to changes of microclimate and/or of the irrigation regime were sensitively reflected in corresponding changes of Pp. Analysis of the data show that transpirational water loss during the morning hours was associated with a transient rise in turgor pressure gradients within the leaflets. Subsequent recovery of turgescence during the afternoon was much faster than the preceding transpiration-induced water loss if the plants were well irrigated. Our data show the enormous potential of the leaf patch clamp pressure probe for leaf water studies including unravelling of the hydraulic communication between neighbouring leaves and over long distances within tall plants (trees).
